Lixiana Lawsuit: Lymphoma, or an autoimmune disorder in about a third of patients, as well as frequent and long-lasting responses to immunosuppressive therapy. On rare occasions, pure red cell aplasia can occur in a patient treated with recombinant erythropoietin, due to development of an autoantibody that inactivates both the pharmacologic erythropoietin and the patients endogenous erythropoietin.Acute, transient suppression of erythropoiesis can be caused by infection with parvovirus B19, which has specific tropism for erythroid precursor cells. In nor­mal individuals, parvovirus B19 infection causes an erythemic rash (fifth disease) and no more than a modest drop in hemoglobin levels. However, patients with underlying chronic hemolytic anemias such as sickle cell disease develop a sudden and marked drop in hemoglobin, owing to a combination of acute suppression of erythropoiesis and ongoing rapid destruction of circulating red cells.

Diamond-Blackfan anemia is a rare disorder (about five per million births) that is both genetically and clinically heterogeneous. Anemia is usually detected either at birth or within the first year of life but occasionally may appear later in life. Affected babies often have underlying skeletal (particularly thumb [Fig. 4-4B]), renal, cran­iofacial, or cardiac anomalies. Short stature is common. Similar to that in acquired pure red cell aplasia, the bone marrow in Diamond-Blackfan anemia has a paucity of erythroid precursors, whereas myeloid precursors and megakaryocytes are nor­mal, giving rise to normal peripheral white cell and platelet counts. Like children with Fanconi anemia, those with Diamond-Blackfan anemia are at increased risk of developing malignancies. About half of children with the Diamond-Blackfan anemia clinical phenotype are heterozygotes with a mutation in one of the proteins of the small or large ribosome subunit. In addition, red cells of affected individu­als often have markedly increased activity of adenosine deaminase, an enzyme in the purine salvage pathway, which can be used to support the diagnosis. It is not yet clear how either the defect in a ribosomal protein or the enhanced adenosine deaminase activity contributes to the pathogenesis and clinical phenotype. Nor is it clear why most patients respond to steroid therapy.

Patients may develop anemia often accompanied by thrombocytopenia and occasionally leukopenia when the bone marrow space is secondarily invaded by one of several different types of disease processes, a phenomenon referred to as myelophthisis. The most frequent cause of myelophthisic anemia is metastatic cancer. Breast, lung, and prostate carcinomas are particularly frequent culprits. Metastatic cancers not only replace the marrow but also often activate marrow fibroblasts, leading to extensive deposition of collagen. This reactive fibrosis dis­torts the marrow microenvironment, disrupting the production of hematopoietic cells and leading to the release of immature marrow elements. These deleteri­ous effects on marrow function are reflected in peripheral blood films, which generally show prominent tear-drop red cells and the presence of nucleated red cells, sometimes accompanied by immature myeloid forms. The tumor cells often appear in large clumps in marrow aspirates and can usually be readily distin­guished from normal hematopoietic cells. Shows clumps of tumor cells in the marrow of patients with retinoblastoma (A) and bladder carcinoma (B). In some instances the tumor cells cannot be recovered in bone marrow aspirates because of the marrow fibrosis and are seen only in biopsies. At the point at which myelophthisic anemia emerges, cancers have advanced to the point at which ther­apy seldom induces remission.

Lixiana Lawsuit: In all organisms from bacteria to man, iron is by far the most important metal­lic element. Its outer shell of electrons is ideally poised for complex coordination chemistry, enabling the binding of ligands such as oxygen as well as participa­tion in critical oxidation-reduction reactions. Iron is essential not only for the biological activity of heme proteins such as hemoglobin, myoglobin, and cyto­chromes but also as a key cofactor in a number of enzymes spanning a wide range of metabolism. However, because of irons high degree of reactivity, it can catalyze the generation of oxygen free radicals and other toxic species, leading to cellular and tissue injury by way of protein cross-links, lipid peroxidation, and damage to DNA. Therefore, in order for iron to safely fulfill its biological functions, an exqui­site degree of control is required. In this chapter we will review the basic elements of iron homeostasis: absorption, transport, utilization, recycling, and excretion. During the last decade, understanding of these processes has been enormously enhanced by the molecular cloning and characterization of critical genes, some of which were discovered by investigation of mutant mice and zebra fish whose phenotypes suggested perturbed iron metabolism.

Sale and effective transport and utilization of iron are achieved by tight regulation at the level of both individual cells and the organism as a whole. The expression of a number of proteins that play critical roles in iron metabolism is regulated by the intracellular concentration of iron. This is achieved through a consensus stem loop sequence in the messenger ribonucleic acids (mRNAs) that encode these proteins. When iron is scarce, two iron regulatory proteins (IRPs) bind specifically to this stem loop and modify either the stability or rate of translation of the mRNAs, whereas when intracellular iron is abundant, the IRPs assume a conformation that precludes mRNA binding. Systemic iron metabolism is regulated by the circulat­ing polypeptide hormone hcpcidin, which controls both dietary iron absorption from the gut and release of recycled iron from macrophages.

The dietary sources of iron vary considerably according to geographic location, cul­tural tastes, and economic status. Iron in food consists of inorganic salts and organic complexes derived from plants as well as heme from animal sources. Digestion of grains, vegetables, and fruits in the stomach and duodenum results in the release of ferric iron. As depicted in Figure 5-1, normal individuals absorb only 1 to 2 mg of iron per day, primarily at the villous tips of duodenal enterocytes. A ferrireductase at this site reduces the iron to its ferrous form, allowing it to enter the cell through a luminal transmembrane channel, the divalent metal transporter DMT1 (Fig. 5-2). A portion of the iron that has entered the enterocyte may be stored within a porous multimeric protein cage called ferritin. Ferrous iron exits from the cell through the transport protein ferroportin, which is localized within the plasma membrane on the abluminal or basolateral side of the enterocyte. Here the iron is rapidly oxidized to the ferric form that binds transferrin, the plasma protein responsible for iron transport throughout the circulation. The export of iron from the duodenal enterocyte can be suppressed by hepcidin, a small polypeptide hormone produced in the liver. ^r11ie binding of hepcidin to its receptor, ferroportin, triggers the lattcr’s internalization and subsequent degradation. As a result, the rate of egress of iron from the enterocyte is markedly dampened.

Lixiana Lawsuit: The hemoglobin is degraded with the release of its iron into ferritin stores. Similar to the mechanism of its exit from the duodenal enterocyte, iron exits from the macrophage via ferroportin and is bound to transferrin in the plasma. The flux of iron from macrophages back to the bone marrow is about 20 mg per day, a much greater proportion of the daily utilization than the influx of iron from the duodenum (about 1-2 mg/day). Thus in vivo iron homeostasis invests heavily in a high-capacity, high-throughput cycle in which iron derived from senescent red cells is delivered to the bone marrow for incorporation into new red cells.

Because free iron is so toxic to cells and tissues, it is important that whatever iron is not being used for synthesis of heme or for other purposes is sequestered within the cell as a storage depot that can be tapped as needed. The challenge of safe and highly bioavailable dynamic storage of iron is met by ferritin, a protein that assembles into a 24-subunit cage surrounding an inner core of iron hydroxide. The production of ferritin is exquisitely attuned to the cell’s needs. As shown in Figure, when iron is scarce, ferritin production is halted because the binding of IRPs to the stem loop iron in the 5′ end of ferritin mRNA blocks translation. In contrast, when iron is abundant, the IRPs can no longer bind to the stem loop, and translation is unimpeded. With increasing accumulation of cellular iron, some of the ferritin becomes denatured and is converted to hemosiderin, from which iron is less readily mobilized. The preponderance of body iron is stored as ferritin and hemosiderin in two sites shown in Figure 5-1: about 600 mg in reticu­loendothelial macrophages that include hepatic Kupffer cells and about 1000 mg in hepatic parenchymal cells. These estimates pertain to men of all ages. Women in the childbearing age group have less stored iron because of blood loss from menses and iron usurpation by the fetus during pregnancy. Because the accumu­lation of iron stores is a very slow process, children also have low levels of liver and macrophage iron.

Iron deficiency is the most prevalent cause of anemia worldwide. In the vast major­ity of cases, it is due to blood loss. Heavy menstrual blood How (menorrhagia) and pregnancy frequently lead to iron deficiency in women in the childbearing age group. Gastrointestinal bleeding is commonly encountered in males and females of all age groups, owing to a variety of lesions including esophageal varices, gas­tritis, peptic ulcer, diverticula, polyps, cancer, and hemorrhoids. In parts of the world where intestinal parasites such as hookworm are endemic, iron deficiency anemia is particularly widespread and severe. Patients with upper intestinal mal­absorption, such as celiac disease, develop anemia because of impaired uptake of iron from the duodenum. Infants whose diets consist primarily of cow’s milk often become iron deficient. However, the prevalence has been lessened by increased breast feeding and the widespread use of iron-fortified formulas. Although inad­equate diet is an uncommon cause of iron deficiency, adolescents are at risk if their nutrition consists primarily of non-nutritious snack foods. Because the elliciency of iron absorption is enhanced by low gastric pH, elderly people with achlorhydria are at increased risk of becoming iron deficient.

The signs and symptoms of iron deficiency are primarily based on the degree of anemia, as discussed in Chapter 3. However, there are clinical features associated specifically with iron deficiency. Both children and adults may evince pica, a pecu­liar need to chew or gnaw on non-digestible substances such as clay (geophagia) or ice (pagophagia). Much less commonly, patients with severe iron deficiency may have concave nail beds (spoon nails or koilonychia), fissures at the angles of the mouth, or a thin membrane web in the esophagus that can cause dysphagia. There is evidence that iron deficient children may have impairment in cognition and learning that cannot be explained by the degree of anemia. It is less certain whether adults have compromised mental or physical performance due to iron deficiency per se.

The development of iron deficiency can be tracked quite accurately by changes in laboratory results. Incipient iron deficiency is characterized by normal hemoglo­bin, hematocrit, red cell indices, and serum iron level but absence of iron stores in the liver and in macrophages. As the deficiency becomes more severe, the mean red cell volume falls, followed by a decrease in hematocrit and hemoglobin con­centrations. During this time, serum ferritin and iron levels fall, whereas serum iron binding capacity (total transferrin) rises. With further worsening of the defi­ciency, the patient becomes increasingly anemic, and microcytosis is then accom­panied by hypochromia, a decrease in mean red cell hemoglobin concentration. The blood smear reveals small red cells with an increase in central pallor, along with abnormalities in red cell shape, including pencil forms and a wide range in cell size. These morphologic changes arc illustrated in Figure. The white blood cell count is normal, but the platelet count is often elevated for unclear reasons.

Lixiana Lawsuit: Oral administration of iron salts, particularly ferrous sulfate, has been standard therapy for nearly a century. However, most patients have difficulty tolerating oral iron, owing to gastrointestinal symptoms such as heartburn and constipation. Recently developed preparations of soluble iron-carbohydrate complexes have proven to be safe and effective when administered intravenously, and they offer assurance of full iron replacement without dependence on patient compliance. molecular adaptation has provided a number of safeguards to protect the body against oxidative damage from free iron. How­ever, there are both inherited and acquired disorders in which these safeguards are not adequate to prevent morbidity and mortality resulting from excess iron. Irrespective of etiology, patients with significant iron overload share a number of clinical and laboratory features. The target organs vulnerable to damage include the heart, liver, and endocrine glands, particularly pituitary, gonads, and pancre­atic islets. Not surprisingly, laboratory results in disorders of iron overload are the mirror opposite of those in iron deficiency.

Inherited disorders of iron overload involve detects either in hepcidin expression or in its receptor ferroportin. The most commonly encountered form of heredi­tary hemochromatosis is due to a single missense mutation (C282Y¹) in the gene HFE, which encodes a transmembrane protein that is homologous to major histo­compatibility class 1 proteins and, like them, binds to beta-2 microglobulin. This mutation is encountered in about 10% of individuals of European ancestry. Thus, about 1 in 400 people of European lineage are homozygotes. Heterozygotes have no clinical manifestations of hemochromatosis. The penetrance of the defect in homozygotes is low; only about 10% of homozygotes are at risk for developing organ damage from iron overload. In those affected, the signs and symptoms are not apparent until middle age in men and even later in women, owing to iron loss from menstruation and pregnancy. In addition to findings that are a direct conse­quence of damage to the heart, liver, and endocrine glands, patients with heredi­tary hemochromatosis often have increased skin pigmentation and complain of fatigue and arthralgia.

Much less commonly, adult-onset hereditary hemochromatosis can be caused by mutations in transferrin receptor 2 and ferroportin. In addition, there are rare kindreds with juvenile hemochromatosis who develop iron-induced organ damage early in life as a result of mutations in either hepcidin or a protein called hemojuvelin. The molecular pathogenesis of hereditary hemochromatosis has been dramatically clarified by the discovery of hepcidin and its key role in regulating iron homeostasis. HFE, transferrin receptor 2, and hemojuvelin all participate in the up-rcgulation of hepcidin transcription. Thus, inactivating mutations of these genes as well as of hep­cidin deprive cells of this key regulator and result in iron overload due to enhance­ment of absorption from the gut and egress from macrophages.

Serum transferrin saturation is the best screening test for detecting patients with iron overload. The diagnosis of hereditary hemochromatosis often can be validated by demonstration of homozygosity of the C282Y HFE mutation. If this lest is negative, a liver biopsy and/or further genetic analysis may be required. Adults with hereditary hemochromatosis generally respond quite well to reg­ular phlebotomies to lower their iron stores. If begun prior to the development of organ damage, this intervention has proven effective in preventing diabetes, cardiac failure, and cirrhosis.

Lixiana Lawsuit: Heme takes place in mitochondria. In certain congenital and acquired anemias, there is a block in the incorporation of iron into heme in erythroid cells and a buildup of iron in mitochondria. This results in the appearance of ringed sidero- blasts, erythroid precursors with iron-laden mitochondria that can be detected with a Prussian blue stain. Hemoglobin production tends to be defective in sideroblastic anemias, sometimes giving rise to a popula­tion of microcytic red cells. Congenital sideroblastic anemia is very uncommon. Most affected indi­viduals are males who have inherited a mutation in the X-linked gene encoding erythroid-specific 8-aminolevulinic acid synthase, the rate-limiting step in heme biosynthesis. In contrast, acquired sideroblastic anemias are quite often encountered. In some patients there is a transient and reversible dysregulation of erythropoiesis following exposure to a toxic substance, most commonly ethanol but occasionally a drug such as the antibiotic chloramphenicol. Ringed sideroblasts are also fre­quently seen in patients with myelodysplastic syndromes, a relatively common cause of anemia in the elderly.

Flematopoiesis depends upon orderly cell division for the logarithmic expansion of progenitor cells into large numbers of circulating blood cells. In the megaloblastic anemias, DNA synthesis is impaired, leading to slowing or arrest of cellular divi­sion during the DNA synthesis phase of the ccll cycle (S phase). A high fraction of cells suffering from such defects undergo programmed cell death (apoptosis). In the bone marrow, the decreased survival of hematopoietic progenitors leads to reduced production of circulating cells (ineffective hematopoiesis). Because RNA synthesis and cytoplasmic differentiation are relatively unaffected, progenitors and progeny that survive are enlarged (macrocytic). The main cause of megaloblastic anemias is deficiency of either cobalamin (vitamin B_p) or folic acid, vitamins that are essential for DNA replication and repair. In addition, chemotherapeutic drugs that inhibit DNA synthesis can result in findings similar to those seen in cobalamin or folate deficiency. It is not surprising that the clinical phenotype extends to other tissues that rely on continuous and robust cellular proliferation and differentiation, particularly the gastrointestinal tract.

Cobalamin is a complex organic molecule consisting of a tetrapyrole corrin ring, similar in structure to heme except that the divalent metal atom in the center of the ring is cobalt rather than iron. Like heme iron, the cobalt atom in the corrin ring binds to two axial ligands. One is a benzimidazole nucleotide, whereas the other can be either a methyl group (methylcobalamin) or an adenosyl group (adenosylcoba- lamin). Cobalamin is found in all foods of animal origin including meat, fish, and dairy products. Food cobalamin is tightly bound to proteins. Following ingestion, some cobalamin in food is transferred to human haptocorrin in saliva. As depicted in Figure 6-1, the acidic environment of the stomach enables efficient release and transfer of the remaining food cobalamin to haptocorrin in gastric juice. After tran­sit to the duodenum, the increase in pH enables the transfer of cobalamin from haptocorrin to intrinsic factor, a transport protein secreted by gastric parietal cells.

The cobalamin-intrinsic factor complex resists digestion and travels down the gut until it encounters epithelial cells in the distal ileum that express cubilin, a receptor with specificity for this bimolecular complex. The cobalamin that is absorbed in the ileum exits the basolateral side of the mucosal epithelial cell into the plasma where it traverses the portal circulation into the liver. Here cobalamin binds transcobala- min, a plasma transport protein that is functionally analogous to transferrin, the transport protein for iron. As in iron homeostasis, the liver is the principal storage site for cobalamin. The uptake of the circulating transcobalamin-cobalamin complex by receptors on plasma membranes is the principal and probably the only way.

Loryna Class Action Lawsuit News – 2/16/2012: Loryna may be linked to serious negative side effects. If you took Loryna and believe you suffered negative side effects as a result, contact us today so that we can make arrangements for a free consultation with a law firm that is investigating cases related to the side effects of Loryna.

Loryna Class Action Lawsuit: An emerging concept of GP IIb/IIIa inhibition, based on evidence from two trials, is that these agents appear to be able to reduce the size of an evolving non-ST-elevation MI, and potentially prevent the development of myocardial ne­crosis. In the troponin substudy of PRISM-PLUS, patients randomized to tiro- fiban plus heparin and aspirin had a significantly lower peak troponin level as compared with patients who received heparin and aspirin alone. This observation was made among patients who had a negative CK-MB on admis­sion. In PURSUIT, using peak CK-MB as a measure of infarct size, it was observed that infarct size, either the index MI or a recurrent MI, was signifi­cantly smaller in patients treated with eptifibatide. Thus, when using these potent antiplatelet therapies early in the course of treatment, there appears to be an immediate reduction of the severity of the presenting illness, which is similar to the beneficial effect of chronic aspirin use in reducing the severity of the pre­senting acute coronary syndrome.

Thrombolytic therapy has dramatically reduced mortality following acute myo­cardial infarction. Its benefit is due to early achievement of infarct-related artery patency, which limits myocardial infarct size, decreases left ventricular dysfunc­tion, and improves survival. While thrombolytic therapy has proved to be a major advance in the treatment of patients with acute myocardial infarction, current regimens are limited by failure of initial reperfusion, inadequate perfusion with delayed flow (TIMI grade 2 flow), reocclusion, and reinfarction in sig­nificant percentages of patients. Because these problems are associated with increased subsequent mortality, and because platelets play a central role in failed reperfusion, reocclusion, and reinfarction, attention has turned to the promising glycoprotein IIb/IIIa inhibitors.

In the setting of ST-elevation MI, IIb/IIIa inhibition was first used following thrombolysis in the Thrombolysis and Angioplasty in Myocardial Infarction (TAMI)-8 trial using abciximab following tissue plasminogen activator (tPA). A consistent dose-dependent inhibition of platelet aggregation was observed and major bleeding was not increased. Eptifibatide was tested in the Integrilin to Manage Platelet Aggregation and Combat Acute Myocardial Infarction (IMPACT-AMI) trial. In addition to accelerated, full-dose tPA, aspirin, and heparin, patients were randomized to ep­tifibatide, at one of six doses, or placebo. The highest dose of eptifibatide ap­peared to improve the 90-min rate of TIMI grade 3 flow (66 vs. 39% for placebo; p = 0.006). More recently, a pilot study combined full-dose streptokinase (1.5 million U/h) and three doses of eptifibatide (180-^g/kg bolus and either 0.75-, 1.33-, or 2.0-^g/kg/min infusion for 24 h) or placebo. Adding the IIb/IIIa inhibitor led to a modest improvement in early complete reperfusion (TIMI grade flow 3 at 90 min) from 38% with placebo to approximately 50% with eptifibatide. The highest dose of eptifibatide was associated with increased bleeding and was discontinued. Further testing of eptifibatide is planned with reduced-dose thrombolytic agents.

The combination of a reduced-dose fibrinolytic agent and a GP IIb/IIIa inhibitor was tested in the TIMI-14 trial, using tPA, streptokinase, and reteplase; in SPEED (Strategies for Patency Enhancement in the Emergency Department) using rete- plase; and in INTRO-AMI and several ongoing trials. In the TIMI-14 trial dose-ranging phase, 681 patients with ST-segment- elevation MI meeting with standard eligibility criteria were randomized within 12 h of onset of chest pain to receive one of four reperfusion regimens (each with several dose levels): accelerated (full-dose) tPA alone (the control arm); reduced-dose tPA plus abciximab; reduced-dose streptokinase plus abciximab; or abciximab alone. All patients received aspirin and heparin, with the initial heparin dosage being 70-U/kg bolus and a 15-U/kg/h infusion in the tPA control arm, and 60-U/kg bolus and a 7-U/kg/h infusion in the abciximab groups.

Loryna Class Action Lawsuit News: Additional Information and Resources

Loryna Class Action Lawsuit: Abciximab alone was associated with a rate of TIMI grade 3 flow at 90 min of 32% and patency rate of 48% (43). The combination of streptokinase and abciximab produced only slight improvement in 90-min TIMI grade 3 flow: 42% in the 0.5-MU group; 39% in the 0.75-MU group; and 47% in the 1.25-MU group. The 1.5-MU regimen plus abciximab was discontinued after four of six patients developed a major hemorrhage, one of whom had an ICH. Of the various dosing regimens of tPA tested, the best angiographic results were obtained using a 50-mg dose given as a 15-mg bolus and a 35-mg infusion over 60 min. The rate of TIMI grade 3 flow at 90 min was 77% compared with 62% for tPA alone (p = 0.02). Overall patency was achieved in 93% of patients with the combination of abciximab and half-dose tPA compared with 78% for full-dose tPA alone (p = 0.09). An even greater difference was observed at 60 min: accelerated tPA achieved only 43% TIMI grade 3 flow at 60 min compared with 72% for 50-mg tPA plus abciximab (p = 0.0009). Major hemorrhage was similar (approximately 6%) among the tPA plus abciximab and control groups. In-hospital mortality was low in all groups, ranging from 3 to 5%.

The Orbofiban in Patients with Unstable Coronary Syndromes (OPUS-TIMI)-16 trial tested the oral Il/IIIa inhibitor, orbofiban, in patients with acute coronary syndromes. This trial enrolled 10,288 patients at 888 hospitals in 28 countries. The inclusion criteria were onset of an acute coronary syndromes within 72 h, defined as an episode of rest ischemic pain lasting at least 5 min associated with either positive cardiac enzymes (i.e., an acute MI), ECG changes, or a prior his­tory of coronary or vascular disease. Exclusion criteria included renal insuffi­ciency (creatinine >1.6 mg/dL, increased high bleeding risk, or need for oral anticoagulation. All patients received 150 to 162 mg of ASA daily and were randomized, in double-blind fashion, to one of two doses of orbofiban or placebo. In one group, orbofiban was administered as 50 mg twice daily throughout the trial (50/ 50 group); in the other group, 50 mg was given twice daily for the first 30 days (the highest risk period), and was reduced to 30 mg twice daily for the remainder of the trial (50/30 group). Other treatments were at the discretion of the pa­tient’s physician. The primary endpoint was a composite of death, MI, recurrent ischemia leading to rehospitalization or urgent revascularization, or stroke. The planned sample size was 12,000 patients, but the trial was terminated early after an unexpected finding of increased mortality at 30 days in one of the orbofiban groups.

Mortality through 10 months was 3.7% for the placebo group versus 5.1% in the 50/30 group (p = 0.008) and 4.5% in the 50/50 group (p = 0.11). There were no differences in the primary composite endpoint at 10 months (22.9, 23.1, and 22.8%, for the placebo, 50/30, and 50/50 groups, respectively). Major or severe bleeding (but not intracranial hemorrhage) was higher with orbofiban; it occurred in 2.0, 3.7 (p = 0.0004), and 4.5% (p < 0.0001) of patients, respec­tively. Exploratory subgroup analyses did identify that patients who underwent percutaneous coronary intervention had a lower mortality and a significant reduc­tion in the composite endpoint (p = 0.001) with orbofiban. Two substudies from OPUS-TIMI-16 found that orbofiban led to increases in measures of platelet activation, notably P-selectin. These data are con­sistent with observations of other agents, which induced an apparent prothrom- botic effect, with increases in measures of platelet activation and increases in platelet aggregation when drug levels were low. Interestingly, in the TIMI-12 trial, no increase in P-selectin was observed with sibrafiban therapy. Active research is ongoing, but these initial studies suggest that there may be differences among the various oral IIb/IIIa inhibitors with regard to potential prothrombotic effects.

The Evaluation of oral Xemilofiban in Controlling Thrombotic Events (EXCITE) trial studied xemilofiban in 7232 patients undergoing PCI with either stenting or balloon angioplasty without adjunctive intravenous IIb/IIIa inhibition. Patients were randomized in a double-blind fashion to receive one of two doses of xemilofiban or placebo: All the xemilofiban patients received a first 20-mg dose 30 to 90 min prior to PCI, followed by either 10 or 20 mg three times daily for 6 months. The primary endpoint—death, MI, or urgent revascularization at 6 months—occurred in 13.6% of patients in the placebo group, 14.1% of patients in the xemilofiban 10-mg group, and 12.6% of patients in the xemilofiban 20­mg group (p = NS) (78). There was a trend toward fewer periprocedural MIs over the first 48 h following PCI, but this benefit was not sustained at 30 days or 6 months. Mortality at 6 months was 1.0% for placebo, 1.6% for the 10­mg xemilofiban dose group, and 1.1% in the 20-mg dose group. Major bleed­ing was significantly more common in the xemilofiban-treated patients. Thus, xemilofiban did not significantly reduce cardiac events in this patient popu­lation.

Loryna Class Action Lawsuit: The second Symphony trial was terminated prematurely at the time the results from the first Symphony trial were available (and not due to safety issues). It compared the combination of low-dose sibrafiban plus aspirin vs. high-dose si­brafiban (without aspirin) vs. aspirin alone in 6671 patients with stabilized acute coronary syndromes. With an average follow-up of 90 days, the primary endpoint, death, MI, or severe recurrent ischemia, was not different among the three groups: 10.5% in the high-dose sibrafiban group; 9.2% for low-dose sibrafiban plus aspi­rin vs. 9.3% for aspirin alone. In this trial (but not in the larger first Symphony trial), mortality was significantly higher with the high-dose sibrafiban group: 2.4 vs. 1.7% for the low-dose sibrafiban plus aspirin group vs. 1.3% for placebo. Recurrent MI followed a similar pattern: 6.9% for high-dose sibrafiban, 5.3% for the low-dose plus aspirin group, and 5.3% for aspirin. Major bleeding was more common with high-dose sibrafiban (4.6%), and higher still for the combination of low-dose sibrafiban plus aspirin (5.7%) vs. 4.0% for aspirin alone.

It is an exciting time for the practicing physician given the availability of this important new therapy that can significantly reduce death, MI, or refractory ischemia/urgent revascularization. The benefits apply to essentially all patients undergoing PCI, thereby becoming a new standard of care in this setting. For the huge number of patients with unstable angina and non-ST-elevation MI, IIb/ IIIa inhibition will significantly reduce recurrent ischemic events. The trials to date have targeted the higher risk unstable angina patients—those with ECG changes or positive cardiac enzymes, and thus these are the patients in clinical practice who should be targeted for early use of IIb/IIIa inhibitors.

Platelets are integrally involved in the thrombotic complications of atherosclero­sis. Their contribution to thrombosis complicating a ruptured atherosclerotic plaque is well established. Interference with platelet function, therefore, should help to prevent thrombotic occlusion of arteries affected by atherosclerosis. In­deed, numerous studies have demonstrated that antiplatelet agents decrease ad­verse cardiovascular events in patients with atherosclerosis. This chapter will focus on three such antiplatelet agents: aspirin, ticlopidine, and clopidogrel. It will include a brief review of platelet function followed by a discussion of the mechanisms of action of these antiplatelet drugs. Thereafter, clinical evidence supporting the notion that antiplatelet agents reduce adverse cardiovascular events in patients with atherosclerosis will be presented.

The three principal events in the formation of a platelet plug include platelet adhesion, activation, and aggregation. Platelets normally circulate in an inacti­vated state. Vascular injury and disruption of the endothelial lining initiates the process of platelet adhesion, in which platelets are deposited on the intimal surface of blood vessels. Among the most important substances to mediate platelet adhesion to the vascular surface is von Willebrand factor. It binds suben­dothelial collagen to the platelet glycoprotein Ib-IX-V receptor. Binding of plate­lets to the vascular surface prompts an intracellular signaling mechanism, includ­ing the metabolism of arachidonic acid to thromboxane A₂. In addition, the platelets release constituents of their alpha and dense granules such as p-selectin.

Loryna Class Action Lawsuit News: Information and News

Loryna Class Action Lawsuit: Aspirin inhibits arachidonic acid metabolism and prevents the formation of thromboxane A₂ by irreversibly inhibiting cyclooxygenase via acetylation of a serine moiety. Platelet inhibition occurs approximately 60 min following the oral ingestion of aspirin. The inhibitory effects of platelets last the life of a platelet, which is approximately 10 days. Hemostatic recovery following a single dose of aspirin occurs as new platelets are formed and enter the circulation. Both ticlopidine and clopidogrel are thienopyridines. These inhibit the function of platelet ADP receptors and thereby limit conformational changes in the glycoprotein IIb/IIIa receptor. Inhibition of platelet aggregation occurs ap­proximately 1 to 2 days following administration of these drugs, and 40 to 60% inhibition of ADP-induced aggregation is observed 3 to 5 days following inges­tion. Platelet function is restored approximately 3 to 4 days after discontinua­tion of ticlopidine or clopidogrel.

The beneficial effects of aspirin on cardiovascular outcome in patients with ath­erosclerosis is well established. The Antiplatelet Trialists’ Collaboration per­formed a metanalysis of over 73,000 patients with clinical manifestations of ath­erosclerosis such as acute myocardial infarction, prior myocardial infarction, or prior stroke or transient ischemic attack, in which patients were treated with either antiplatelet therapy or a control. The most widely studied antiplatelet drug was aspirin. Overall, antiplatelet therapy was associated with a 25% odds reduc­tion for the aggregate endpoint of stroke, myocardial infarction, or vascular death. The studies included in this metanalysis, as well as some more recent studies, highlight the efficacy of aspirin in reducing cardiovascular morbidity and mortality in patients with atherosclerosis. Some of the larger studies involving patients with coronary artery disease, cerebrovascular disease, or peripheral arte­rial disease are described below.

In the Antiplatelet Trialists’ Collaboration, antiplatelet therapy, primarily aspirin, was associated with a 29% odds reduction for stroke, myocardial, or vascular death among approximately 20,000 patients with acute myocardial infarction and a 25% odds reduction for these adverse events among approximately 20,000 pa­tients with prior myocardial infarction. The largest trial for acute myocardial infarction included in the Antiplatelet Trialists’ Collaboration was the Second International Study of Infarct Survival (ISIS-2), which randomized over 17,000 patients with acute myocardial infarction to aspirin, streptokinase, both, or neither. Compared to placebo, aspirin was associated with a 23% risk reduction for vascular death, a 50% reduction for nonfatal reinfarction, and a 46% reduction for nonfatal stroke 5 weeks after randomization. The combination of streptokinase and aspirin was more effective than either agent alone in reducing vascular death. The efficacy of aspirin in preventing coronary reocclusion follow­ing thrombolysis for acute myocardial infarction is supported by a metanalysis of 32 studies. Reocclusion occurred in 11% of 419 patients treated with aspirin versus 25% of 513 patients not treated with aspirin, and recurrent ischemic events occurred in 25% of 2977 patients treated with aspirin compared to 41% of 721 patients who were not treated with aspirin.

Several large trials have demonstrated the efficacy of aspirin in preventing myocardial infarction and death in patients with unstable angina. A Veterans Administration Cooperative study randomized 1256 men with unstable angina to aspirin or placebo for 12 weeks. The incidence of fatal or nonfatal myocardial infarction was reduced by 51% in the group treated with aspirin compared to the group treated with placebo. A Canadian multicenter trial randomized 555 patients with unstable angina to aspirin, sulfinpyrizone, both, or neither to 24 months of treatment. The incidence of fatal or nonfatal myocardial infarction was 8.6% in the groups receiving aspirin compared to 17% in the groups not receiving aspirin, resulting in a 51% risk reduction with aspirin. Theroux et al. compared the efficacy of aspirin, intravenous heparin, both, or neither in 479 patients with unstable angina. Approximately 6 days following randomization, myocardial infarction had occurred in 11.9% of patients who received neither aspirin nor heparin, in 3.3% who received any aspirin, in 0.8% of those who received only heparin, and in 1.6% of patients who received both aspirin and heparin. The Research Group on Instability in Coronary Artery Disease in Southeast Sweden (R.I.S.C.) randomized 796 men with unstable angina or non-Q-wave myocardial infarction to aspirin or placebo. After 1 year, myocardial infarction occurred in 21.4% of patients treated with placebo and in 11% of patients treated with aspirin. Thus, aspirin treatment reduced the risk of nonfatal or fatal myocardial infarction by 48%.

Loryna Class Action: The findings from the observational studies that hormone users are at generally lower risk from coronary disease do not necessarily imply cause and effect. Women and their physicians decide on estrogen therapy. Often the health status of the woman will have an important influence on this decision and on the results of studies that examine these women. Thus, some have argued that hormone use is merely a marker rather than a cause of good health. Most of the observational studies reviewed here have provided some in­formation bearing on this critical point. The Nurses’ Health Study tried to evalu­ate whether increased medical care of women using postmenopausal hormones might be responsible for the benefit observed. In an analysis limited to women who reported regular physician visits (50% of the cohort), results were sim­ilar to those found in the larger population of all subjects: the relative risk for major coronary heart disease was 0.52 (95% CI, 0.37-0.74) for current hormone use.

Another approach is to examine the risk profile of estrogen users and non­users to determine whether the differences, if any, are sufficient to explain the large decrease in risk among estrogen users. Barrett-Connor observed that, in a cohort of postmenopausal women, those taking estrogens reported more in­tensive health-care behavior, including frequent screening tests such as blood cholesterol measurement and mammograms. An examination of determinants of estrogen therapy in 9704 women participating in a large, multicenter study of osteoporotic fractures found that hormone users tended to be better educated, less obese, and drank alcohol and participated in sports more often than nonusers. Similarly, in a prospective study of randomly selected premenopausal women, observed a better cardiovascular risk factor profile prior to hormone use among the women who subsequently took hormones at menopause than among women who did not.

For hormone users compared to nonusers and, after further adjustment for high blood pressure, history of angina, MI, or stroke, alcohol use, smoking, body mass index, and age at menopause, the relative risk was virtually the same (RR = 0.79; 95% CI, 0.71-0.88), implying an equivalent risk status for users and nonusers. In addition, to further examine this issue, the Nurses’ Health Study conducted an analysis limited to a subgroup of low-risk women (i.e., those with no diagnosis of hypertension, diabetes, or high serum cholesterol who were nonsmokers and had a Quetelet’s Index below 32 kg/m²). Even with such restrictions, the relative risk for coronary disease was almost 40% lower for current hormone users. In summary, to explain the overall benefit of hormone therapy as a result of con­founding by health status, one would have to presume unknown risk factors which are extremely strong predictors of CHD and very closely associated with estrogen use.

LMWHs, like UFH, bind a cofactor called antithrombin to produce their predominant anticoagulant effect. Binding is mediated through a unique pentasac­charide sequence of the mucopolysaccharide that increases by 1000-fold both the interaction between antithrombin and thrombin (factor II_a), and the interaction between antithrombin and factor Xa. However, a minimum chain length of 15 to 18 saccharides (corresponding to a molecular weight of > 5400 daltons) is required to inactivate thrombin. In contrast, inhibition of factor Xa can occur with short polysaccharide chains. Thus, one potentially important distinc­tion between UFH and LMWH, and among LMWHs themselves, is the varying ratio of factor Xa to factor IIa. The factor Xa:IIa activity for UFH is approxi­mately 1.2, while ratios for the various LMWH preparations vary from 2 to 4. Table 1 lists LMWHs in order of anti Xa:IIa ratio.

Loryna Class Action: The ESSENCE study was a double-blind, placebo-controlled trial that ran­domly assigned 3171 patients with angina at rest or non-Q-wave myocardial in­farction to receive 2 to 8 days therapy with either 1 mg/kg of enoxaparin subcuta­neously twice daily or continuous intravenous UFH. At 14 days, the risk of death, myocardial infarction, or recurrent angina was significantly lower in the patients assigned to enoxaparin than in those assigned to UFH (16.6% vs. 19.8%; p = 0.019). At 30 days, the risk of this composite endpoint remained significantly lower in the enoxaparin group (19.8% vs. 23.3%; p = 0.016). The need for revas­cularization procedures at 30 days was also significantly less frequent in the pa­tients assigned to enoxaparin (27.1% vs. 32.2%; p = 0.001). The 30-day inci­dence of major bleeding complications was 6.5% in the enoxaparin group and 7.0% in the unfractionated-heparin group, but the incidence of bleeding overall was significantly higher in the enoxaparin group (18.4% vs. 14.2%; p = 0.001), primarily because of ecchymoses at injection sites. Thus, the ESSENCE trial indicates that enoxaparin plus aspirin is more effective than UFH plus aspirin in reducing the incidence of ischemic events in patients with unstable angina or non-Q-wave myocardial infarction in the early phase. This benefit was associated with an increase in minor, but not major, bleeding.

In TIMI-11B, 3910 patients with unstable angina or non-Q-wave MI were randomized to either intravenous UFH for 3 to 8 days followed by subcutaneous placebo injections, or enoxaparin during both the acute phase (initial 30-mg IV bolus followed by injections of 1.0 mg/kg every 12 h for 3 to 8 days) and outpa­tient phase (injections every 12 h for up to 43 days of 40 mg for patients weighing >65 kg and 60 mg for those weighing <65 kg). The primary endpoint (death, myocardial infarction, or urgent revascularization) occurred by 8 days in 14.5% of patients in the UFH group and 12.4% of patients in the enoxaparin group (OR 0.83 [0.69 to 1.00]; p = 0.048) and by 43 days in 19.7% of the UFH group and 17.3% of the enoxaparin group (OR 0.85 [0.72 to 1.00]; p = 0.048). During the first 72 h and also throughout the entire initial hospitalization, there was no differ­ence in the rate of major hemorrhage in the treatment groups. During the outpa­tient phase, major hemorrhage occurred in 1.5% of the group treated with placebo and 2.9% of the group treated with enoxaparin (p = 0.021). Consistent with the ESSENCE findings described above, the results of the TIMI-11B study demon­strate that enoxaparin is superior to UFH in reducing a composite of death and serious cardiac ischemic events during the acute management of patients present­ing with unstable angina, but does not cause a significant increase in the rate of major hemorrhage.

Last, the FRAXIS trial (29) randomized 3468 patients in a double-blind fashion to one of three treatment regimens: UFH (5000 IU bolus, followed by an infusion for 6 ± 2 days); nadroparin for 6 days (nadroparin 86 anti-Xa IU/kg IV bolus, followed by twice-daily subcutaneous injections for 6 ± 2 days); or nadroparin for 14 days (same dose as the prior group for 14 days). No statistically significant differences were observed among the three treatment regimens with respect to the primary outcome (cardiac death, myocardial infarction, refractory angina, or recurrence of unstable angina at day 14). The absolute differences between the groups in the incidence of the primary outcome were: -0.3% (p = 0.85) for the nadroparin 6-day group vs. the UFH group, and +1.9% (p = 0.24) for the nadro- parin 14-day group vs. the unfractionated heparin group. Furthermore, there were no significant intergroup differences regarding any of the secondary efficacy out­comes. However, there was an increased risk of major hemorrhage in the nadro­parin 14-day group compared with UFH (3.5% vs. 1.6%; p = 0.0035). Thus, similar to the FRISC-I trial findings with dalteparin, treatment with nadroparin for 6 days provides similar efficacy and safety to treatment with UFH for the same period. A prolonged regimen of nadroparin (14 days) does not provide any additional clinical benefit and is associated with an increase risk of major hemorrhage.

The use of LMWH as an adjunct to fibrinolytic therapy is actively under investi­gation (33-37). Preliminary results from the HART-II angiographic study (37) demonstrated slightly higher rates of infarct artery patency (80.1% vs. 75.1%; p = NS) and TIMI grade 3 flow rates (52.9% vs. 47.6%; p = NS) at 90 min among 200 patients receiving tPA and enoxaparin (30 mg IV bolus followed by 1 mg/ kg SQ twice daily for >72 h) compared to tPA and UFH. Clinical event rates were similar and reocclusion among patients with a patent artery at 90 min tended to be less frequent in those randomized to enoxaparin (5.9 vs. 9.8%; p = NS). In another angiographic study (36), dalteparin was compared with placebo in patients receiving streptokinase. TIMI grade 3 flow 20 to 28 h later tended to be higher in patients treated with dalteparin (68% vs. 51%; p = 0.10) and the number of ischemic episodes on continuous ECG monitoring was lower (16% vs. 38%; p = 0.04).

Loryna Class Action: Direct thrombin inhibitors, as indicated by the class name, do not require anti­thrombin or another cofactor to inhibit the function of thrombin. Direct thrombin inhibitors inhibit all the major actions of thrombin, including thrombin-induced generation of fibrin, thrombin-induced platelet activation, as well as thrombin’s autocatalytic reaction. Potential advantages of direct thrombin inhibitors over heparin include: inhibition of clot-bound thrombin lack of inhi­bition by activated platelets; and stable anticoagulant response since no cofactor is required. The prototypic direct thrombin inhibitor is hirudin, a polypeptide consisting of 65 amino acids derived from the leech Hirudo medicinalis. Hirudin selec­tively binds thrombin in a 1:1 fashion at two locations: the carboxy terminus of hirudin binds to the substrate recognition site, the domain of thrombin that recognizes fibrinogen or the platelet and the amino terminus of hirudin binds to the catalytic site of thrombin. Hirudin does not inhibit factor Xa, IX, kallikrein, activated protein C, plasmin, tissue plasminogen activator, or other enzymes in the coagulation or fibrinolytic pathways. Although hirudin does not bind covalently to thrombin, the dissociation rate is extremely slow; thus, hirudin essentially irreversibly inhibits thrombin.

Lepirudin was compared to heparin in the OASIS-2 trial (56). While there were trends toward a reduction in cardiovascular death or MI at 72 h (2.0% vs. 2.6%; p = 0.04) and at 7 days (3.6% vs. 4.2%;p = 0.08), there was an attenuation of this benefit by day 35, in contrast to the sustained superiority of enoxaparin over UFH (30). Furthermore, major bleeding requiring transfusion was more fre­quent with lepirudin (1.2% vs. 0.7% for heparin; p = 0.01). The authors per­formed a metanalysis of all the hirudin trials and observed a modest 10% benefit favoring hirudin, although this was not statistically significant for patients with unstable angina/non-ST-elevation MI at 35 days. The Food and Drug Ad­ministration (FDA) recently reviewed the available clinical data and did not ap­prove hirudin for use in unstable angina/non-ST-elevation MI, citing the lack of sustained benefit and increased risk of bleeding.

In the HIT-3 trial, excess intracranial hemorrhage was observed with lepirudin (0.4 mg/kg bolus, 0.15 mg/kg/h infusion) compared to UFH (3.4% vs. 0%) among 302 patients receiving tPA. In the subsequent HIT-4 trial (71), involv­ing 1208 patients and using a lower dose of lepirudin (0.2 mg/kg bolus, 0.5 mg/ kg subcutaneously b.i.d.) in combination with streptokinase, TIMI flow grade 3 was observed in 40.7% in the lepirudin and in 33.5% in the heparin group (p = 0.16). No difference were seen between lepirudin and heparin in the rate of hemorrhagic stroke (0.2% vs. 0.3%), reinfarction (4.6% vs. 5.1%), or mortality (6.8% vs. 6.4%) at 30 days. Thus, intravenous lepirudin (as administered in HIT- 3) as an adjunct to tPA appears to be unsafe, and lower dose lepirudin in combina­tion with streptokinase does not significantly improve reperfusion or clinical out­comes.

Angiographic trials with other direct thrombin inhibitors in conjunction with fibrinolytic therapy have also been conducted. In a pilot study and the HERO trial, a trend toward improved early (90 to 120 min) TIMI grade 3 flow was observed with the higher dose of Hirulog as compared with heparin in patients receiving streptokinase. Testing with other agents found modest or no improvements compared with heparin. HERO-II, an international phase III trial of approximately 17,000 patients with ST-elevation MI treated with strep­tokinase, is randomizing patients to either Hirulog or UFH and should complete enrollment in the latter half of 2000.

Loryna Class Action: Despite tremendous initial enthusiasm for the direct thrombin inhibitors, their current role in clinical practice is limited to use as an anticoagulant in patients with heparin allergy, or in the treatment of heparin-induced thrombocytopenia and thrombotic syndrome. Ongoing and future research, particularly as adjunctive therapy in patients receiving fibrinolysis or percutaneous coronary intervention, may identify other clinical situations in which these drugs could play a useful role. However, studies to date have identified a narrow therapeutic window, mar­ginal evidence of incremental, sustained efficacy over UFH, and the possibility of a ‘‘rebound’’ effect. These problems represent challenges to this class of anti­thrombotic drugs.

Because approximately 4 million patients each year are admitted to hospitals worldwide with unstable angina or acute myocardial infarction (MI), and nearly 1 million patients annually worldwide undergo percutaneous coronary intervention (PCI), physicians have focused a great deal of attention on developing new treat­ments for these acute coronary syndromes (ACS). The initiating event of these acute coronary syndromes is rupture of an atherosclerotic plaque followed by local thrombosis. Similar pathophysiology is present during PCI, which is essen­tially a ‘‘planned’’ plaque disruption.

The peptide and peptidomimetic inhibitors (e.g., tirofiban and eptifibatide) are competitive inhibitors of the IIb/IIIa receptor, with very rapid half-lives of dissociation from the IIb/IIIa receptor (10-20 s). Thus, the level of plate­let inhibition is directly related to the drug level in the blood. Since both inhibitors have short half-lives, when the drug infusion is stopped the antiplatelet activity reverses after a few hours, which is a potential benefit for avoiding bleed­ing complications. The third group of GP IIb/IIIa inhibitors are the oral agents. Within this group, there are also the two broad types of agents, those that are competitive inhibitors, and those that bind tightly to the receptor. The oral drugs are usually prodrugs, which are absorbed and then converted to active compounds in the blood. The oral agents all have longer half-lives, such that they can be given once, twice, or three times daily in order to achieve relatively steady levels of IIb/IIIa inhibition.

Abciximab was also found to be beneficial when started 24 h prior to a PCI in the c7E3 Fab Antiplatelet Therapy in Unstable Refractory Angina (CAPTURE) trial: death, MI, or urgent revascularization was reduced by abcix­imab from 15.9 to 11.3% (p = 0.012) (27). In the Evaluation of IIb/IIIa inhib­itor for Stenting (EPISTENT) trial (28), compared with stenting with only aspirin and heparin, the rate of death, MI, or urgent revascularization at 30 days was significantly reduced in both abciximab groups—from 10.8 to 5.3% for stent plus abciximab (p < 0.001) and 6.9% for balloon angioplasty with abciximab (p = 0.007) (28). Benefits were maintained at 6 month and 1 year, with a significant reduction in 1 year mortality in patients treated with stent plus abcix- imab compared with stent alone. In addition, a metanalysis of abciximab trials has shown that there is a significant reduction in mortality when GP IIb/ IIIa inhibition is used.

Loryna Lawsuit: Clinical evidence demonstrating anti-inflammatory and plaque-stabilizing effects of statin drugs has only recently become available. The first study to address whether patients with evidence of inflammation benefited from statin therapy was performed within the Cholesterol and Recurrent Events (CARE) trial, a secondary-prevention evaluation of pravastatin. Consistent with studies of primary prevention, participants in the CARE trial with elevated CRP levels were found to have higher risks of recurrent coronary events than those with lower levels of CRP. However, a clinically apparent interaction between statin therapy and inflammation was also observed in that the proportion of recurrent events prevented by pravastatin was 54% among those with inflammation com­pared with 25% among those without inflammation. Moreover, long-term therapy with pravastatin significantly reduced plasma levels of CRP in a manner that was not related to this agent’s effects on LDL cholesterol. In fact, in this hypothesis-generating study, there was no relationship between the change in CRP and the change in LDL cholesterol at the end of the 5-year follow-up period. Thus, these initial data provided clinical evidence that statin therapy may well have anti-inflammatory properties. While the mechanism of this effect is uncertain, the CARE data provide evidence for possible clinical relevance of laboratory observations demonstrating nonlipid effects of the HMG-CoA reductase inhibitors, such as modulation of immune function, antiproliferative effects on vascular smooth muscle, and antithrombotic properties, as well as morphological ef­fects.

Two major studies have now addressed the validity and clinical importance of these observations. The first, the Pravastatin Inflammation/CRP Evaluation (PRINCE) trial, was explicitly designed to address three questions. First, can the effects of pravastatin on CRP observed in the CARE trial be confirmed in a direct hypothesis-testing setting? Second, how quickly does any effect of pravastatin on CRP occur and are the effects of pravastatin on CRP truly inde­pendent of changes in LDLC? And third, are the effects of pravastatin on CRP observed in CARE (a secondary-prevention study) equally present in primary- prevention populations? In total, the PRINCE trial evaluated 2884 patients: 1182 in a secondary- prevention cohort who received pravastatin 40 mg daily, and 1702 in a primary- prevention cohort randomly allocated to either pravastatin 40 mg daily or placebo. Prior use of lipid-lowering therapy within the previous 6 months was not allowed, and those in the primary-prevention arm had to have LDL choles­terol levels greater than 130 mg/dL. Blood samples were collected at baseline.

As ensured by the randomization process, baseline levels of CRP (median 0.20 mg/dL), total cholesterol (231 mg/dL), LDL cholesterol (143 mg/dL), and HDL cholesterol (40 mg/dL) were virtually identical in the two primary- prevention arms of the PRINCE trial. In contrast, compared with those in the primary-prevention cohort, those with a prior history of cardiovascular disease who were enrolled in the secondary-prevention cohort of PRINCE had signifi­cantly increased CRP levels (median 0.26 mg/dL). As would be expected, those in the secondary-prevention cohort were also older and more likely to smoke or have diabetes, and the group had a higher proportion of aspirin users than the primary-prevention cohort. During the course of the study, highly significant re­ductions in total cholesterol, LDL cholesterol, and triglycerides were observed in the pravastatin groups, as was a clinically important increase in HDL choles­terol (all p values <0.001). No change was observed in any of these parameters among those allocated to placebo.

Loryna Lawyer: The main analyses of PRINCE were the effects of statin therapy at both 12 and 24 weeks. In the primary-prevention cohort, pravastatin reduced median CRP levels by 16.9% compared with placebo at the end of the 24-week study period (p < 0.001). This effect was present at 12 weeks (median reduction in CRP with pravastatin 14.7%; p < 0.001). As shown in Figure 7, these effects were observed in all the PRINCE prespecified subgroups, including analyses stratified by age, smoking status, gender, obesity, and lipid levels. As had been hypothesized, virtually no association was observed between CRP and lipid levels either at the study beginning or during follow-up. In fact, in correlational analy­ses, less than 2% of the variance in the change in CRP could be explained by the change in any lipid parameter. Virtually identical effects were also seen in those in the secondary-prevention cohort of the study.

Several decades ago, homocystinuria, a rare pediatric condition, was noted to be associated with musculoskeletal abnormalities and the development of ven­ous thromboembolism and arterial disease in adolescence. The underlying metabolic defect for this condition was shown to be decreased enzymatic activ­ity of cystathionine beta-synthase. This deficiency was associated with in­creased levels of methionine and homocysteine and a decrease in blood levels of cysteine. Later investigations of a patient with elevated homocysteine levels and similar clinical findings, but with a low concentration of methionine in the plasma and evidence of abnormal vitamin B₁₂ metabolism, led to the conclusion that another defect could account for elevated homocysteine levels and vascular disease.

A large variety of factors have been associated with increased levels of homocys­teine, and only the key topics in healthy outpatients will be considered here. Fasting blood homocysteine concentrations are typically greater in the elderly compared with middle-aged adults, and higher in men than in women. Analyses of the Framingham Heart Study and the National Health and Nutrition Examination Survey data have shown that the prevalence of elevated homocyste­ine (>14 |j.mol/L) increases with age in both sexes, and plasma homocysteine levels are inversely correlated with vitamin intake. Vitamins Bj, B₂, B₆, B₁₂, folate, niacin, retinol, vitamin C, and vitamin E have all been studied, but the greatest interest has been shown for vitamins B₆, B₁₂, and folate, as these nutrients act as cofactors for several homocysteine metabolic pathways.

Low vitamin B₁₂ status can also account for elevated homocysteine levels, as this vitamin is a necessary cofactor in several homocysteine metabolic steps. Inadequate production of intrinsic factor in the stomach can result in a severe vitamin B₁₂ deficiency, with substantially elevated homocysteine concentrations, but this etiology is an infrequent cause of low vitamin B₁₂ status. Hypochlorhydria and achlorhydria are more common than inadequate intrinsic factor deficiency, especially in older individuals, and can lead to impaired absorption of vitamin B₁₂ because low pH is needed to dissociate B₁₂ from food.

Loryna Lawyer: There are many genetic causes of elevated homocysteine levels. Enzymatic de­fects and variants have been associated with cystathionine beta-synthetase, meth­ylene tetrahydrofolate reductase (MTHFR), thermolabile and nonthermolabile variants, and methionine synthetase, to name a few. The MTHFR variant 677- C ^ T has gotten the most attention, as it is relatively common and affects 10 to 15% of North Americans and 5 to 25% of Europeans. This MTHFR variant has also been studied for associations with cardiovascular disease, and homo­zygosity has generally been associated with an increased occurrence of disease; however, several studies demonstrated no association between the MTHFR and vascular outcomes. A meta-analysis concluded that a modest association with increased risk for cardiovascular disease was present. The inconsistent asso­ciation between MTHFR variants and vascular disease may be partially explained by population dietary data. Persons homozygous for MTHFR 677-C ^ T and who had suboptimal folate status were especially likely to have elevated homo­cysteine levels.

Other studies have not always corroborated these results. In some instances, the associations with adverse outcomes were demonstrated for nutrient status, but not for homocysteine levels. For instance, higher homocysteine levels were not associated with greater risk in a MRFIT-nested case-control analysis (20); the ARIC study demonstrated higher folate and B₆ intake to be associated with lower CVD risk but associations with higher homocysteine were not significant (21); and the Nurses’ Health Study investigators found that higher folate and B₆ intake was associated with lower cardiovascular risk. Elevated homocysteine concentrations in the plasma may potentiate thrombin generation and may have relevance in the setting of acute coronary syndromes. A study of approximately 100 persons with acute coronary syndromes was found to have positive associa­tions with F1 + 2 and Factor Vila levels. It has been proposed that hyperho- mocysteinemia potentiates a procoagulant state that may adversely affect the en­dothelium and enhance tissue factor activity.

Large-scale interventional data that reduce homocysteine levels and dem­onstrate favorable effects on cardiovascular risk are lacking, but vitamin supple­ments are being included in a variety of ongoing studies and the results should be forthcoming. The minimal daily dose of folic acid that appears to have maximal efficacy to decrease plasma homocysteine is estimated as 0.4 ^g/day, with higher doses not generally being more effective. It is recommended that vitamin B₁₂ deficiency be ruled out prior to initiating folic acid therapy. Alterna­tively, persons on folic acid therapy can be supplemented with a dose of 400 to 1000 |J.g/day of vitamin B₁₂. The dose of vitamin B₆ recommended was 25 to 50 mg/day and there is little risk of developing complications such as sensory neuropathy at this supplement level.

Loryna Lawyer: New factors associated with increased risk for coronary heart disease arouse great interest and enthusiasm, kindling the hope that we may enhance identification of individuals at risk for CHD. Important concerns are that such metabolic factors be biologically plausible, measurable, repeatable, strong, graded, and treatable (37-39). Measurement issues include accuracy and precision for the factor in the laboratory and evidence of low or modest variability in the clinical setting. If the laboratory or biological variability is very large, the utility of the measurement for predictive purposes is seriously reduced. Many years of experience and stan­dardization of measurements are available for some vascular risk factors, and less experience is available for homocysteine. New risk factors may provide clues to pathogenesis and in some instances may improve our ability to predict disease. The ability to predict new vascular disease events should be demonstrated after consideration of the core set of factors that are currently available, including age, sex, blood pressure, cholesterol or LDL cholesterol, HDL cholesterol, smoking, and diabetes mellitus. This criterion is often not met in new investigations and considerable experience and relatively large data sets and follow-up may be nec­essary to assure that new factors, such as homocysteine, prove useful in predicting vascular disease risk.

Elevated homocysteine levels may be accompanied by decreased blood levels and intake of folate, vitamin B₆, or vitamin B₁₂. These vitamins are important cofactors in the metabolism of homocysteine, and border­line deficiencies are relatively common, affecting approximately 30% of the el­derly participants in the Framingham Heart Study. Greater intake of these vitamins in the diet, with supplements in the form of multivitamins, or through fortification of foods, has led to less vitamin deficiency and a decrease in the prevalence of elevated homocysteine levels. Fortification of the food supply in the United States with folate was announced in early 1996 with a mandated enactment date of January 1, 1998. Analyses of homocysteine and folate levels before and after fortification have been undertaken in Framingham Heart Study participants and showed a dramatic decline in the prevalence of low folate levels, a reduction in the prevalence of elevated homocysteine from approximately 20 to 10%, and a modest decrease in mean homocysteine levels from approximately 10 to 9 |J.mol/L.

Lupus anticoagulants or nonspecific inhibitors interfere with the assembly of procoagulant complexes. In vitro, these antibodies are associated with the pro­longation of phospholipid-dependent blood-clotting times. Characteristically, clotting times return to normal with the addition of exogenous phospholipid. Lu­pus anticoagulants may demonstrate specificity for blood-clotting proteins, in particular prothrombin. However, the mechanism by which they promote throm­bosis is unknown. Lupus anticoagulants are likely associated with a high risk of first and recurrent thrombosis as well as recurrent pregnancy loss.

LAC are a heterogeneous group of autoantibodies, which prolong the clot­ting time in a variety of assays and may demonstrate specificity for beta- 2 glycoprotein-1. LAC do not prolong clotting times in assays in which phospholipid is present in excess. This suggests that LAC inhibit in vitro coagula­tion by interfering with the assembly of procoagulant complexes on phospholipid surfaces. This observation also forms the basis for the test for LAC—a prolonged clotting time, in a phospholipid-limited assay system, that normalizes with the addition of excess phospholipid confirms the presence of LAC. Anecdotal experi­ence suggests that lupus anticoagulants are much less common than anticardio- lipin antibodies, that they are infrequently transient, and that they are associated with a high risk of complications, although none of these observations has been adequately studied. Furthermore, laboratory assays for lupus anticoagulants.­

Loryna Settlement: An overview of this selective approach to the use of ACE inhibitors for higher risk myocardial infarction patients indicates that approximately 20 to 30 lives are saved in the first month of treatment and that, with continued therapy, approximately 60 to 80 lives are saved per 1000 patients treated. It is impor­tant to underscore that the benefits of the use of an ACE inhibitor in myocardial infarct patients could be considered as additive to conventional therapy with thrombolytics, beta-blockade, and even aspirin. Therefore, it is fair to conclude that use of an ACE inhibitor in these patient populations results in a new and complementary modality to reduce risk of death and other major cardiovascular events.

The only ‘‘fly in the ointment’’ in the field of ACE inhibitors and acute myocardial infarction was from the CONSENSUS II study, which showed a nega­tive trend when ACE inhibitor therapy was started intravenously in the first day of the infarct and then continued orally for the projected study duration of 6 months. With over 100,000 patients in randomized, placebo-controlled trials of different designs, agents and durations, the consensus of international experts strongly recommends the use of an ACE inhibitor starting early and continued long term for patients at higher risk. These authoritative guidelines do indi­cate that there are sufficient rationale and data for clinicians to adopt a more global approach for the use of ACE inhibitors in an even broader population.

Additional mechanisms to explain the ACE inhibitor influence on coronary events soon came from novel experimental studies that revealed an important interface between the renin-angiotensin system and the balance between throm­bolysis and thrombosis. An infusion of angiotensin-II raised plasminogen activa­tor inhibitor-1 (PAI-1), which would alter the fibrinolytic balance toward throm­bosis. The randomized use of ACE inhibitors in patients with acute myocardial infarction did indeed lower PAI-1 levels and, particularly, the balance of PAI-1 to intrinsic tPA. Augmented PAI-1 levels had been associated with greater risk of infarct and others had speculated that reduced PAI-1 may be an indication of restoration of endothelial function. In the TREND study, the long-term treatment with the ACE inhibitor quinipril led to a better restoration of coronary endothelial function. Along these lines, it has been postulated that lowering angiotensin-II with an ACE inhibitor would reduce superoxide anions, promote nitric oxide, and limit further vascular damage.

In the mid-to-late 1990s, three major trials were initiated to determine whether an ACE inhibitor would reduce atherosclerotic events. The Heart Out­comes Prevention Evaluation (HOPE) study selected patients for clinical evi­dence of vascular disease with prior myocardial infarction, stroke, peripheral vas­cular disease, or diabetes plus another risk factor and randomized to conventional therapy plus placebo or ramipril. Patients with heart failure or known depressed ejection fraction were excluded. The Prevention of Events with Angiotensin Converting Enzyme Inhibition (PEACE) study, specifically designed as a follow- up of SAVE, included patients with documented coronary disease and an ejection fraction over 40% randomized to conventional therapy plus either trandolapril or placebo. The EUropean trial on Reduction Of cardiac events with Perindo­pril in stable coronary Artery disease (EUROPA) randomized patients with coro­nary disease regardless of their ejection fraction to either perindopril or placebo.

Loryna Settlement: HOPE was the first of these major studies to be completed. Randomization to ramipril resulted in a convincingly consistent 20% and greater reduction in ath­erosclerotic events, such as cardiovascular death, myocardial infarction, and stroke. The HOPE study results are based on a substantial number of clinical events and consistent findings were present in all predefined subgroups. Again, the small reduction in blood pressure with the ACE inhibitor in and of itself could not explain the magnitude of the clinical benefits in this patient population. Within the HOPE study, a mechanistic trial evaluating carotid arterial thickness as a surrogate marker of the atherosclerotic process did demonstrate a dose-dependent reduction in ca­rotid thickness with the use of an ACE inhibitor. Other important mechanistic observations such as the reduction in the development of diabetes and diabetic complications may provide additional key insights. Indeed, the hemoglobin A1C levels in the subpopulation evaluated was reduced by chronic therapy with the ACE inhibitor. The HOPE study expands both the patient population who will receive benefits from ACE inhibitor therapy as well as the potential mechanisms that can be evoked to explain these impressive beneficial actions.

With the obvious broad overlap in patients who would benefit from both of these agents, a negative interaction with the concomitant use of these two agents would have major public health implications. At the outset, it must be acknowledged that there is yet to be a two- by-two trial of aspirin and ACE inhibitors as there was of thrombolytics and aspirin in ISIS-2. Indeed, with the now established benefits of both of these agents, such a trial in which patients would have either of these life-saving thera­pies withheld would be deemed unethical. Decisions will have to be based on the experience of prior trials. Since most of the major aspirin trials were con­ducted prior to the knowledge of the survival benefit of ACE inhibitors, there are few data on concomitant use. On the other hand, there is extensive experience in the ACE inhibitor trials with patients on aspirin.

The initial hypothetical question of a possible interaction, whereby the con­comitant use of both drugs offsets the potential benefits of an ACE inhibitor, was proposed by Donald Hall and his colleagues. A mechanistic study of patients with severe heart failure and marked neurohormone activation observed that the vasodilating effect of enalapril was offset by the concomitant use of aspirin. Since one of the important actions of an ACE inhibitor, aside from reducing the production of angiotensin-II, is to impede the breakdown of bradykinin, which also enhances the production of prostaglandins, it was reasoned that an aspirin effect on inhibiting prostaglandin synthesis could offset some of the hemody­namic benefits of administering an ACE inhibitor. Indeed, their work on the he­modynamics of severe heart failure was confirmed by others. This is similar to the use of nonsteroidal anti-inflammatory agents that had long been known to exacerbate signs and symptoms of heart failure, impairing renal function, and even offsetting antihypertensive effects of a variety of therapeutic compounds. Hall provided mechanistic underpinning and focus for important questions regarding a potential for aspirin to offset some of the clinical benefits of ACE inhibitor use in patients with severe heart failure.

Subsequently, a subgroup analysis from the SOLVD studies did indicate that there was a trend for less of a survival benefit in patients randomized to the ACE inhibitor who were reported to be on aspirin at baseline. Proponents of an important negative interaction whereby aspirin offsets some of the benefits of an ACE inhibitor could also turn to the CONSENSUS-II acute myocardial infarction study to bolster these positions. Conversely, subgroup analyses from other large studies appear to refute these observations. With the proven benefits of both of these agents independently and the overlapping clinical profile of pa­tients that should be receiving these therapies simultaneously, this becomes a critical question to resolve.

Loryna Settlement: In the short term, broad-inclusion analysis of 96,712 patients, aspirin was used at baseline in 86,884 (89.4%) and not in 10,228 patients (10.6%). Aspirin use was not randomized and, as it turns out, there was a marked disparity in risk profile with respect to use of aspirin. Patients who did not receive aspirin were less likely to receive thrombolytics or beta-blockers, were older, and were more likely to have had pulmonary congestion as is manifested by Killip Class 2 and 3. Not surprisingly, regardless of ACE inhibitor status, the non-aspirin-treated patients had more than twice the mortality rate (14.4 vs. 6.5%, no aspirin vs. aspirin) in these short-term studies. The test for heterogeneity between the reductions in risk of death produced by randomization to the ACE inhibitor in the presence or absence of aspirin use at baseline was not significantly different. This analysis is inclusive of CONSENSUS-II, which is frequently cited as an example of an aspirin-ACE interaction where no benefit of the ACE inhibitor was observed in the presence of aspirin.

Since we have not had (and are unlikely to have) a direct two-by-two test of these two proven agents, interpretation of the information from the existing studies must suffice to generate our clinical conclusions. Along these lines, it is fortunate that use of ACE inhibitors for reduction of cardiovascular events is an extremely well-studied area. Particularly so in patients with myocardial in­farction, with over 100,000 patients in randomized trials and the majority on aspirin, providing a good data set from which to draw these conclusions. Just as the antiplatelet trialists have formed a collaboration to collectively extract more data from their individual studies, so have the ACE inhibitor myocardial infarction investigators. Representatives from eight major trials have pooled their individual data to provide more precise point estimates and to particularly probe prospective subgroup analyses for both efficacy and safety. The ACE Inhibitor Myocardial Infarction Collaborative group prospectively determined that the broad-inclusion, short-term studies should be analyzed separately from the elec- tive-inclusion, long-term studies. Both of these systematic overviews (metanal- ysis) have been completed and recently published.

Symptomatic arterial occlusive disease generally occurs when the artery lumen is reduced to half normal. Atherosclerosis is by far the most common cause of peripheral arterial occlusive disease. Other etiologies must be considered in individuals who do not have risk factors for atherosclerosis or in those who have an unusual distribution of arterial occlusive disease. These etiologies include Ta­kayasu arteritis and giant cell arteritis. Both of these arteritides may result in stenosis of any extremity vessel, visceral vessels, or the aorta. Other forms of vasculitis also result in symptomatic arterial occlusive disease. Thromboangiitis obliterans should be suspected if the distal arteries of the upper and lower extrem­ities are involved, particularly in those who smoke cigarettes. Acute arterial occlusion occurs as a consequence of embolism or thrombosis in situ. Thrombosis can develop acutely in atherosclerotic arteries or it can occur in locations such as the renal arteries in the presence of antithrombin-III deficiency.

Symptomatic lower extremity atherosclerosis is reported in 3% of those individuals over age 50. In individuals greater than 70, over 25% have evi­dence of peripheral arterial occlusive disease by noninvasive testing. The preva­lence of peripheral arterial disease is threefold greater when determined by nonin­vasive testing for arterial stenosis rather than by questionnaires regarding symptoms, consistent with the observation that two-thirds of affected individuals are asymptomatic by traditional history. Yet, in a recent community screening program, these asymptomatic individuals had lower functional capacity than those without peripheral arterial disease, as well as an increased risk of cardiovas­cular death.

Loryna Settlement News: Information and News

Loryna Settlement: Noninvasive testing for lower extremity arterial occlusive disease provides objec­tive information that, together with the history and physical examination, is used to make decisions regarding further evaluation and treatment. These tests can be used for screening, for physiological assessment of hemodynamically signifi­cant stenosis, and to follow-up after revascularization procedures. The most sim­ple and widely used noninvasive test of extremity arterial occlusive disease is measurement of systolic pressure using a sphygmomanometric cuff and a Doppler device to detect arterial flow. Duplex scanning extends the capabilities of nonin­vasive testing by identifying anatomical and physiological information at the sites of arterial stenoses.

Three-dimensional arterial reconstruction using magnetic resonance im­aging (MRI) arteriography and spiral CT arteriography can provide non­invasive assessment of the distal aorta and iliac vessels, but presently with less clarity than is available with invasive arteriography. Contrast arteriography is necessary to completely evaluate the anatomical extent of disease in the distal aorta and lower extremity arteries. It is generally performed only in order to determine the optimal revascularization procedure because of its invasive nature and risk. The functional significance of the arterial occlusive disease can be confirmed by invasive pressure measurements proximal and distal to the stenosis, and can be determined before and after administration of a vasodilator.

The combination of B-mode ultrasound scanning and pulsed Doppler interrogation allows noninvasive assessment of the anatomy and hemodynamic abnormalities in the arterial segments from the distal aorta to the popliteal trifurcation. For exam­ple, soft plaque and thrombi may have similar acoustic properties to blood and, therefore, may not be detected by B-mode imaging, but they will result in a flow disturbance that can be detected by Doppler evaluation. Equipment for peripheral arterial testing includes a linear array transducer, operating at a gray-scale fre­quency of 4 to 10 MHz, and capable of providing frequencies above 3 MHz for Doppler signal analysis. Gray-scale imaging is used to examine the arteries and the presence of detectable atherosclerotic plaque or thrombus. The pulsed Doppler spectral analysis is used to document the presence of blood flow and to determine blood flow velocity. Normal Doppler waveforms in the lower extremity will be triphasic, with a peak velocity less than 120 cm/s. Color Doppler flow mapping allows for a rapid survey of the arteries in order to identify those sites where more labor-intensive and precise Doppler spectral analysis is needed. Still, full evaluation of the lower extremity arteries takes from 1 to 2 h.

Duplex examination can be combined with exercise testing to detect disproportionate velocity increases with exercise and therefore identify the le­sions responsible for a patient’s symptoms. The duplex scan is potentially supe­rior to angiography in the evaluation of iliac artery, and in determining the hemo­dynamic status of ostial lesions in the profunda and superficial femoral arteries. Peripheral artery bypass grafts can be followed serially with duplex ultrasonogra­phy. The first month after surgery and every 1 to 2 years following surgery are key times to identify early changes consistent with stenosis within the graft. The criteria for discrete stenosis in bypass grafts is similar to that in native ves­sels. In addition, a peak systolic velocity that is decreased to 45 cm/s indicates a dramatically increased likelihood of graft failure and provides a rationale for early intervention. In addition, duplex evaluation is likely to be similarly useful in the follow-up of peripheral arteries following percutaneous revascularization.

Loryna Side Effect News- 2/16/2012: You deserve to be compensated if you took Loryna and suffered side effects that the public was not warned about. Contact us today and we will arrange a free consultation with a lawyer experienced in pharmaceutical and medical device ligation that can advise you of your legal rights.

Loryna Side Effect: Until recently, we only had aspirin, but now a number of new, highly effective medications have been approved to decrease platelet stickiness and prevent the formation of blood clots. The last few years have brought remarkable progress and hope for the stroke survivor. In addition to our good old standby aspirin, the “Grande Dame” of blood clot prevention, we now have multiple medications that also decrease platelet stickiness and clot formation—and go a long way toward preventing anoth­er stroke or vascular death. One has only to turn on the television or open a magazine and you will see advertisements for these medications.

Furthermore, treating a stroke patient’s depression with an­tidepressants also has been found to enhance his physical and cognitive rehabilitation. Each antidepressant has its own side effects, including sleep disturbances, agitation, and sexual dysfunction. Some of the old­er antidepressants interfere with cognition (the ability to “know”) and should be avoided. A clinician must take a patient’s individu­al stroke symptoms into account when determining which medi­cation is best. Our newer antidepressant medications are so effective that frequently the importance of psychology is ignored. However, both medication and counseling are important. Studies have shown that used together the result is superior to either used alone.

When physicians mention the use of a stimulant medication, the first reaction is usually less than enthusiastic. Patients and their families picture children with attention deficit disorders or con­jure up the horrors of amphetamine abuse. But this close-minded thinking may make them miss a very important treatment both in the early and latter phases of stroke rehabilitation. According to experimental evidence, ani­mals treated with amphetamines immediately after their stroke recover to a higher functional level. In other words, stimulants may either have a protective effect on brain cells or assist in their recovery after a stroke. This is still far from common practice in most acute care hospitals, but that can change as more research shows the effectiveness of these medications.

Loryna Side Effect: Like their antidepressant cousins, tranquilizers can help decrease the emotional anxiety that accompanies stroke, which, if left un­checked, could sabotage the rehabilitation process. And this anxiety is very real. The fear of a stroke recurring, the fear that it is still in progress, the overwhelming fear of how their lives will change—all these can create irritability, anxiety, and insomnia. Tranquilizers can help ease the pain of these fears, but, as with antidepressants, they must be closely monitored. They can interfere with cognitive abilities. Their use should be “time lim­ited” to avoid dependence. Side effects include drowsiness, dizziness, and possible addiction.

Yes, stroke survivors can have seizures, but they are not common. If someone you love suffers from seizures as a result of stroke, however, there is help. Anticonvulsants usually will control sei­zures. However, regular blood tests will be required to adjust the dosage. The proper levels must be present in blood in order for this medication to work. Too little and it will not be effec­tive against seizures; too much and there is the danger of side effects—which include nausea, drowsiness, balance problems, and liver abnormalities.

Although not a medication, it seemed best to cover this procedure in this chapter. Carotid endarterectomy is an operation that is performed when too much cholesterol has built up in the carotid artery in the neck. Developing the skills to perform this operation has not been as difficult as deciding which patient is an appropriate candidate. Recently, a large study helped identify which patients would ben­efit most; the findings show that determination should be based on how much the carotid artery is narrowed and whether the per­son is currently experiencing any stroke symptoms.

When injured or in pain, we want to go to the best doctor, the best specialist, for our condition. When it comes to dental work or orthodontics, we want to know we are in good hands. Even outside the world of medicine, the best is something we strive for: a restaurant to celebrate a birthday, a vacation in the sun, a car for our family. We want to try, as much as possible, to get the best quality for our money.

Rehabilitation is no exception. There are good rehabilita­tion facilities and there are bad ones—and which you choose can make all the difference in whether or not your loved one gets the care he needs and deserves. And, believe it or not, there are re­habilitation facilities that are better than others—at the same or lower cost. Further, since studies have shown that the average stroke survivor lives an additional seven and a half years, there is no doubt that doing some “rehabilitation detective work” and finding the right facility can have positive results!

Loryna Side Effect: True, there are certain rules, specific guidelines, that thera­pists must follow. Therapists must be trained and educated very carefully. They are required to receive an advanced degree in their specific area, in addition to hands-on work in the field. In short, by the time you see any of the therapists on your rehabilitation team, they have had a great deal of education and experience. But there is more than expertise at work in rehabilitation. Some people have that extra “something,” a talent that school- books cannot supply. A therapist who interacts with you in a way that makes you feel secure, who motivates your loved one to try her very best, who helps and doesn’t hinder—this is a rehabilita­tion therapist worth seeking out. A good facility will have this type of therapist on staff. It should be the unspoken credo of the entire rehabilitation team.

Although the ads you see for nursing homes make them sound like a dream come true for the elderly—more like resorts or rehabilitation facilities than nursing homes—the reality is that they do not always ensure progress, and they may even hinder ul­timate success. Changing a sign on the building from ABC Home for the Aged to ABC Rehabilitation Center doesn’t change the facts. The statistics speak for themselves: studies have found that patients in inpatient rehabilitation hospitals were three times more likely to be discharged home than those who went to nursing homes.

Do stroke patients do as well in a skilled nursing facility as in a true rehabilitation hospital? Are they as likely to be discharged home and back to the care of their loved ones? The answer to both questions: definitely not! And there are scientific studies to prove it. That’s right: three times more likely to sleep in their own bed, eat with their families, and kiss their grandchildren goodnight. Knowing this, where would you or a loved one want to go if you had a stroke?

The goal of a human being is to be independent and to en­joy a life that is as productive and of good quality as possible. A person who has had a serious illness or injury is no excep­tion. Whether it’s as basic as helping a person who has had a stroke learn bladder and bowel routines so that she can maintain some level of independence and dignity, or as complex as aid­ing a person who has lost her memory, rehabilitation works for your loved one, your family, and you. The highest correlation of self-esteem in a person is the ability to control one’s bladder and bowels. Inpatient rehabilitation facilities have entire programs to focus just on this area.

Loryna Side Effect News: Hospital acute care. This is the place you go to immedi­ately after an accident or a stroke. It is the “emergency room of rehabilitation care” where you’ll find an actual emergency room, an intensive care unit, and operating rooms. In an ideal world, rehabilitation starts here. A medical team performs a variety of diagnostic tests that may include a blood workup, x-rays, or brain scans. A respiratory therapist will ensure that lungs are kept clear. Other members of the rehabilitation team will provide proper po­sitioning and movement to prevent bedsores, weakened muscles, or spasticity.

Day program. Think of a day program as the workplace or a school. In this type of rehabilitation program, you will receive all of the usual therapies and medical treatments with a daily “work” day that may last from four to eight hours. At day’s end, the patients return home to sleep, eat, and be with their families. This is the perfect setting for the patient who still needs multiple therapies but is able to return home at night and on the weekends to be with her family. Transitional living. This is exactly as it sounds: a transi­tional residence that is halfway between a rehabilitation hospital and home, sweet home. It is a place for those who have “gradu­ated” from their rehab program, but are not yet ready to reen­ter their community and live at home. In this supervised setting, people work on such skills as menu preparation, group social skills, and behavior management, while continuing their reha­bilitation program.

Rehabilitation does not take place in a vacuum. Work performed on the lower extremities is not done without coordination of speech and other therapies. It is not a question of three weeks for physical therapy, followed by six weeks for speech, and ending with four weeks for relearning such basic skills as using a knife and fork and getting dressed.

The rehabilitation team works together, implementing and reinforcing this interrelated approach. The speech therapist knows the progress a patient is making in language and cogni­tive therapy. The occupational therapist knows where the patient stands in activities of daily living. Each team member works in concert with the others, in communication with the others, even working side by side with the others. This makes sense: as a pa­tient learns to use a wheelchair, he also might be learning how to make change in a supermarket. As he learns to walk from his bed to the bath, he also is learning how to shower and get dressed.

Elbert County in Denver, CO has a unique asbestos abatement project to tackle – that of a public landfill and trash compactor site. The site has historically been used to dispose of roofing and building materials, much of which was from before the mid 1970’s when buildings were routinely constructed with an abundance of asbestos. The landfill has been the primary dumping site for such rubbish but then it is compacted into bundles and shipped off to another landfill.

Concern about asbestos at the site arose when a backhoe company began excavating the grounds in preparation to remove an old missile silo. Local residents in the area called in complaints to authorities that contaminants were being spread by the excavation. Subsequent soil tests and tests to the debris at the landfill showed the presence of asbestos. No charges were filed because the asbestos had not yet gone airborne, but rather was contained to the landfill site.

Upon learning of the presence of asbestos among other environmental contaminants, the excavating was ceased and the area was covered, pending professional asbestos abatement services.

Cory Stark, director of Elbert County Emergency Management determined that the backhoe company, Backhoe Services, was operating without having tested the soil first and without a formal contract with the city. As reported by the Denver Post, Backhoe Services could not be reached for comment.

Stark asserts that there has been no danger to local residents so far as the toxins have been contained. Still, local residents have remained cautious and concerned. They are now taking their trash and debris to an alternate dump site.

Asbestos diseases such as lung cancer, asbestosis, and mesotheliomaare the unfortunate result of asbestos exposure. If you have been diagnosed with an asbestos-related disease, contact a mesothelioma lawyer at Sokolove Law today for a free consultation.

Asbestos

If you read the last article we posted about asbestos trust funds, you’ll remember the clever hammock analogy used to describe what they are. If you didn’t read it, you can do so here.

Now, the Government Accountability Office (GOA) – a sort of congressional watchdog group that keeps an eye on government spending of taxpayer dollars – has published a report that reveals the somewhat secretive system of asbestos trust fund payouts.

The report looked at 52 asbestos trust funds that have paid out over 3,000,000 claims for a total of about $17.5 billion. The investigation was prompted by the fact that these asbestos trust funds don’t publish details about their activities, yet do make general information available. Attorneys representing asbestos companies or defendants — in asbestos lawsuits filed by mesothelioma victims – raised a stink about the secrecy of the details and implored congress to get involved. The investigation proceeded to determine if, in fact, these asbestos trust funds were keeping details secret.

The investigation revealed only “one trust’s financial report contained claimant names and amounts paid to these individuals.”

The defendants in asbestos lawsuits have been the critics of asbestos trust fund secrecy. They allege that asbestos lawyers and mesothelioma law firms oversee the operation of these asbestos trust funds to prevent them from revealing how much their clients have been paid. This, they further allege, allows some asbestos attorneys to file claims with multiple trusts that could contradict each other.

The GAO report stated that 98% of asbestos trust fund claims go through what is called an expedited review process, which requires a claim form and some documentation that asbestos exposure happened. Perhaps the lawyers representing the asbestos companies want mesothelioma victims to have to go through much more than that to get the compensation they deserve?

According to the report, 65 percent of asbestos trust funds treat claims information as confidential and privileged. Defendants and insurers want the details to be available to them so they can reduce the value of the claims awarded to mesothelioma victims in court.

If you or someone you know has been diagnosed with mesothelioma and suspect it’s due to asbestos exposure, contact a mesothelioma attorneyat Sokolove Law for a free consultation. Also, write to your local congressman about keeping the details of asbestos trust fund settlements confidential and out of the hands of the asbestos companies

In a health study of Taconite Workers in Iron Range, Minnesota, the number of citizens who died of mesothelioma is higher than they reported a year ago – up from 63 to 82. Researchers found the additional nine cases by checking death records of former residents who moved out of state.

The University of Minnesota is responsible for the study, which started in 2008 and will wrap up as early as mid-2012. So far, results indicate that the rate at which residents have contracted mesothelioma is much higher than it should be.

Mesothelioma is a rare and fatal cancer, caused primarily by exposure toasbestos fibers, which often takes 30 years or more after exposure to show up.

Exactly how Iron Range residents have been exposed to asbestos is a mystery. Speculation includes one theory that workers handled asbestos in certain products then carried it home. Another theory is that processing taconite rock (a low-concentrate iron ore that has been mined and processed in Minnesota since the 1950s) releases asbestos fibers from within the rock into the air. The mystery is what provoked the $4.9 million health study, which was approved by state lawmakers in 2008.

Researchers have collected data on people who worked in mining as far back as the 1920’s. So far, the study shows that out of about 46,000 taconite workers who ever worked in the industry, 1,681 developed some sort of lung cancer.

Currently, the results from more than 2,000 air samples taken over the last two years at Minnesota’s six operating taconite plants show safe dust levels. Asbestos levels are extremely low, according to the study. Silica concentration was found to be higher than acceptable in some cases.

Mesothelioma

The International Mesothelioma Program at Brigham and Women’s Hospital and Harvard Medical School in Boston continue to make progress in malignant mesothelioma research. The scientists and doctors involved with the project are looking for information that will lead to better adjuvant therapies for the rare and deadly disease. Adjuvant therapies are treatments given to help boost the effectiveness of other treatments. In the case of malignant mesothelioma, the term “adjuvant therapies” typically refers to treatments that are administered to patients after they have had tumors surgically removed.

In a recent study, scientists used mice to test potential adjuvant therapies. Human mesothelioma cells were introduced into the test mice, allowed to metastasize (to grow), then surgically removed. This procedure turned the mice into workable test subjects for testing ne mesothelioma adjuvant therapies.

One of the therapies researchers studied on the mice was “intracavitary chemotherapy,” which means applying the chemotherapy drug, paclitaxel, into the cavity of the body around the site where the tumor has been removed just prior to closing the incision. The results of this test on the test mice were encouraging.

In a report published in the Annals of Thoracic Surgery, “Paclitaxel-laded Expansile Nanoparticles in a Multimodal Treatment, Model of Malignant Mesothelioma,” the researchers state: “Treatment with [paclitaxel] improved overall survival in the setting of [the surgery], suggesting that [it] merits further evaluation for intracavitary drug delivery following the surgical resection of malignant mesothelioma.” What this means is that this particular adjuvant therapy may be successful in the survival of mesothelioma patients.

Advancements such as these are very important to patients of malignant mesothelioma, as the cancer is serious and fatal.
