BACKGROUND AND METHODS Thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, fever, central nervous system abnormalities, and renal dysfunction. In early reports the mortality approached 100 percent. A treatment protocol was introduced in 1979 for patients admitted to(More)
BACKGROUND Platelet glycoprotein IIb/IIIa is a membrane receptor for fibrinogen and von Willebrand factor, and it has an important role in platelet aggregation. It is known to be involved in the pathogenesis of acute coronary syndromes. Previously, we found a high frequency of a particular polymorphism, PlA2, of the gene encoding glycoprotein IIIa in(More)
OBJECTIVE Increased circulating levels of hemostatic factors have been associated with arterial and venous thrombosis. Although in vitro evidence suggests that glucocorticoids may activate hemostasis and inhibit thrombolysis, no controlled in vivo studies have examined the effects of glucocorticoids on hemostatic factors. We hypothesized that a 5-day(More)
BACKGROUND Venous thromboembolism (VTE) is a common cause of morbidity and mortality among patients with malignant gliomas. To investigate the pathogenesis of VTE and facilitate targeted prophylaxis strategies, the authors aimed to characterize VTE risk factors in these patients. METHODS The authors conducted a retrospective chart review of 130 adult(More)
Recent studies have focused on the accumulation of cytokines in stored platelet concentrates and the role that these cytokines play in mediating transfusion reactions. To elucidate any additional adverse effects that may be associated with cytokine accumulation, the authors examined whether cytokines, which normally accumulate during routine platelet(More)
BACKGROUND Both inherited predisposition and platelet hyperreactivity have been associated with ischemic coronary events, but mechanisms that support genetic differences among platelets from different subjects are generally lacking. Associations between the platelet Pl(A2) polymorphism of GP IIIa and coronary syndromes raise the question as to whether this(More)
To assess the efficacy of immune globulin in preventing CMV infection, interstitial pneumonia, GVHD and death after BMT, we reviewed and synthesized data from 12 published studies (with 1282 patients) in which immune globulin was used prophylactically in BMT patients, controls were included and clinical outcomes were assessed. Data synthesis indicates that(More)
BACKGROUND Growing evidence suggests that vitamin D deficiency Is associated with clinical coronary artery disease (CAD). The relationship between vitamin D deficiency and subclinical CAD in HIV-infected individuals is not well-characterized. METHODS Computed tomographic (CT) coronary angiography was performed using contrast-enhanced 64-slice(More)
UNLABELLED In alloimmune thrombocytopenia, maternal sensitization to a fetal platelet alloantigen results in fetal thrombocytopenia. Even in primipara, 20% of offspring can suffer intracranial hemorrhage, half of which occur in utero. Ninety percent of subsequent pregnancies will be equally or more severely affected. We describe two patients whose previous(More)
Neonatal alloimmune thrombocytopenia is caused by the transplacental passage of maternal antibodies directed against platelet-specific antigens. Because complications from bleeding may result, prompt institution of therapy may be necessary. Accurate diagnosis by serologic techniques permits appropriate therapy to be administered both prenatally and(More)
