Abstract | OBJECTIVE: We report four cases of neonatal alloimmune thrombocytopenia (NATP) in pregnancies achieved with in vitro fertilization. STUDY DESIGN: Three cases used surrogate carriers, and the fourth a donor egg. Sera from gestational carriers were tested for platelet antibodies by flow cytometry and enzyme-linked immunosorbent assay. Platelet antigen genotyping of biologic mothers, fathers, and surrogates was performed by amplification of DNA by using polymerase chain reaction with sequence-specific primers. RESULTS: In all 4 cases, NATP resulted from an incompatibility between the fetus and gestational carrier for the platelet-specific alloantigen HPA-1a. Four infants were born severely thrombocytopenic (platelets |
