BACKGROUND: Patients with transfusion-dependent β-thalassemia need regular red-cell transfusions. Luspatercept, a recombinant fusion protein that binds to select transforming growth factor β superfamily ligands, may enhance erythroid maturation and reduce the transfusion burden (the total number of red-cell units tran…

This FAIRsharing record describes: The database provides a centralised repository for the data which define the human platelet antigens (HPA). Alloantibodies against human platelet antigens are involved in neonatal alloimmune thrombocytopenia, post-transfusion purpura and refractoriness to random donor platelets.

Neonatal alloimmune thrombocytopenia (NAIT) can cause severe bleeding in the central nervous system (CNS) and death or severe neurologic sequelae. The expression of the PLA1 antigen is detectable as early as 19 weeks of gestation. Alloimmunization can therefore lead to fetal thrombocytopenia very early in pregnancy. U…

Maternal alloimmunization against fetal platelets can cause fetal and neonatal thrombocytopenia (NAIT). The HPA-1a (PIA1, Zwa) antigen is by far the most common antigen implicated in NAIT. However, today another antigen often linked with that affection is HPA-5b (Br(a)). This is a report of 39 cases of NAIT involving…

Platelets from 200 random Dutch blood donors were typed for the human platelet alloantigens HPA-1 to -5 recognized at present and for Naka. Naka is an epitope on glycoprotein IV, not expressed on the platelet of individuals with hereditary GP IV deficiency. Platelet immunofluorescence and monoclonal antibody-specific…

Fetal platelet counts were retrospectively studied in a series of 5,194 consecutive fetal blood samplings (FBS). The mean value was 245 +/- 65 x 10(9)/L, without significant variation between 17 and 41 weeks' gestation. After exclusion of false thrombocytopenia due to contamination with amniotic fluid, 247 fetuses had…

Background. The two most frequent types of microcytic anemia are beta thalassemia trait ( β -TT) and iron deficiency anemia (IDA). We retrospectively evaluated the reliability of various indices for differential diagnosis of microcytosis and β -TT in the same patient groups. Methods. A total of 290 carefully selected…

The protein of human serum, tentatively designated beta(1C)-globulin, was shown to possess serological activity and to be related to the complement system. Another serum protein (beta(1A)-globulin) was identified as the inactivated form of beta(1C)-globulin. Incubation of fresh serum with various immune precipitates o…
