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)
OBJECTIVE Antenatal therapy with intravenous immunoglobulin (IVIG) and prednisone has been shown to improve fetal thrombocytopenia and reduce the incidence of intracranial hemorrhage in neonatal alloimmune thrombocytopenia. Optimization of this therapy for individual patients, however, has yet to be achieved. METHODS In these parallel, randomized,(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)
OBJECTIVES Our purposes were to investigate maternal infusions of intravenous gamma-globulin, to prevent intracranial hemorrhage, and to determine whether 1.5 mg dexamethasone and 60 mg prednisone per day add to the effect of intravenous gamma-globulin. STUDY DESIGN Fifty-four women with alloimmune thrombocytopenia and thrombocytopenic fetuses were(More)
OBJECTIVE This report describes the increased risks of cordocentesis in fetuses affected with alloimmune thrombocytopenia. STUDY DESIGN As part of a multicenter treatment study clinical and laboratory data from five pregnancies with alloimmune thrombocytopenia in which there was a fetal or neonatal loss associated with cordocentesis were reviewed. The(More)
OBJECTIVE Neonatal alloimmune thrombocytopenia is caused by platelet antigen incompatibility between the mother and fetus. Affected fetuses may have severe thrombocytopenia leading to intracranial hemorrhage before or at birth. We sought to treat this condition in utero to prevent these hemorrhages. METHODS Eighteen women who had previously delivered(More)
Fetal and neonatal alloimmune thrombocytopenia constitutes the most common cause of severe thrombocytopenia in fetuses and neonates and of intracranial hemorrhage among term newborns. The cornerstone of therapy involves the use of steroids and intravenous immunoglobulins. Despite the risk of potentially devastating consequences to the fetus, fetal blood(More)
Neonatal alloimmune thrombocytopenia results from the formation of a maternal antibody to a paternal antigen on fetal platelets. Intracranial hemorrhage, which may be antenatal, occurs in approximately 15 to 20 percent of infants with this form of thrombocytopenia. In families with an affected infant, 75 percent of subsequent infants are affected. We report(More)
