BACKGROUND Transfusion-related acute lung injury (TRALI) is now the leading cause of transfusion-associated mortality, even though it is probably still underdiagnosed and underreported. NATIONAL HEART, LUNG, AND BLOOD INSTITUTE ACTION The National Heart, Lung, and Blood Institute convened a working group to identify areas of research needed in TRALI. The(More)
BACKGROUND Some observational studies have reported that transfusion of red-cell units that have been stored for more than 2 to 3 weeks is associated with serious, even fatal, adverse events. Patients undergoing cardiac surgery may be especially vulnerable to the adverse effects of transfusion. METHODS We conducted a randomized trial at multiple sites(More)
BACKGROUND We conducted a trial of prophylactic platelet transfusions to evaluate the effect of platelet dose on bleeding in patients with hypoproliferative thrombocytopenia. METHODS We randomly assigned hospitalized patients undergoing hematopoietic stem-cell transplantation or chemotherapy for hematologic cancers or solid tumors to receive prophylactic(More)
We describe a case of thrombocytopenia and deep venous thrombosis in a boy who received heparin to maintain patency of a central venous catheter. Measurement of the release of serotonin labeled with carbon 14 confirmed the presence of heparin-induced thrombocytopenia. Children receiving heparin therapy should be monitored for the possibility of(More)
Thrombocytopenia, often severe, occurs in 1% to 2% of patients given the fibrinogen receptor antagonist abciximab, a chimeric Fab fragment containing murine specificity-determining and human framework sequences. The cause of this complication has not yet been defined. Studies of 9 patients who developed profound thrombocytopenia (platelets <10 x 10(9)/L [10(More)
BACKGROUND Vancomycin has only rarely been implicated as a cause of thrombocytopenia, and there is only limited evidence that this complication is caused by immune mechanisms. We conducted a study to determine whether thrombocytopenia is caused by vancomycin-dependent antibodies in patients being treated with vancomycin. METHODS We identified and(More)
Thrombocytopenia developing in the course of chemotherapy for malignant disease is usually attributed to drug-induced marrow suppression and/or marrow replacement by tumor. We describe two patients who developed severe thrombocytopenia and hemorrhagic symptoms while being treated with oxaliplatin, 5-fluorouracil, and leukovorin for metastatic colon cancer(More)
Quinine-induced immune thrombocytopenia with hemolytic uremic syndrome (HUS) is a recently defined clinical entity. In this paper we have attempted to characterize the natural history and laboratory abnormalities typical of quinine-induced immune thrombocytopenia associated with hemolytic uremic syndrome in nine patients experiencing ten episodes of the(More)
OBJECTIVE To evaluate the effectiveness and safety of two antenatal treatment regimens designed to optimally protect fetuses against intracranial hemorrhage resulting from alloimmune thrombocytopenia while minimizing the risks associated with fetal blood sampling. The study was limited to "standard-risk" patients, who were defined as women with documented(More)
