Severe fetomaternal alloimmune thrombocytopenia presenting with fetal hydrocephalus.
We report two patients where the finding of isolated fetal hydrocephalus led to the detection of severe fetal thrombocytopenia, using fetal blood sampling. Serological investigation led to the diagnosis of fetomaternal alloimmune thrombocytopenia (FMAIT) due to anti-HPA-1a. Both women had had previous unsuccessful pregnancies probably due to FMAIT; one had had four miscarriages at 17-18 weeks' ...
متن کاملManagement of alloimmune thrombocytopenia: antenatal diagnosis and in utero transfusion of maternal 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. Until recently, we have had no means of detecting and assessing the severity of...
متن کاملAntigen-positive platelet transfusion in neonatal alloimmune thrombocytopenia (NAIT).
Neonatal alloimmune thrombocytopenia (NAIT) is a fetomaternal incompatibility most commonly induced by maternal anti-HPA-1a, IgG alloantibodies against a polymorphic epitope of the glycoprotein IIb/IIIa complex in approximately 97.5% of white patients. Current guidelines recommend transfusion of immunologically compatible platelets to prevent cerebral hemorrhage, the most severe complication in...
متن کاملThe incidence and outcomes of fetomaternal alloimmune thrombocytopenia: a UK national study using three data sources.
Fetomaternal alloimmune thrombocytopenia (FMAIT) is the most common cause of severe neonatal thrombocytopenia in otherwise well, term infants. First pregnancies are often severely affected. This descriptive, population-based national study was undertaken in order to inform the case for antenatal screening. Cases were identified using three sources and capture-recapture techniques used to genera...
