Abstract | UNLABELLED: The HPA-15 platelet (PLT) group was recently described. Severe neonatal thrombocytopenia due to alloimmunization by HPA-15b has very rarely been observed. A 22-year-old mother, gravida 1/para 1, gave birth to a male infant who presented with a severe thrombocytopenia, the PLT count recorded to be 3 x10(9)/L. A few hours after birth, he developed purpura with extensive haematomas but without visceral or intracranial haemorrhage (ICH). Two PLT transfusions were given including one using maternal PLTs. The infant's PLT count was 267 x 10(9)/L on day 6. The maternal platelet group was HPA-15a/a and her infant was HPA-15a/b. Anti-HPA-15b antibodies was found in maternal serum. CONCLUSION:
