We report a case of neonatal allo-immune thrombocytopenia due to fetomaternal human platelet antigen (HPA)-1 incompatibility. Anit-HPA-1b antibodies were detectable in maternal serum. Repeated treatment of the infant with high-dose IgG effectively raised platelet counts transiently, but the patient remained thrombocytopenic for more than 6 weeks. Serological and DNA analysis revealed that the mother was homozygous HPA-1a and the father homozygous HPA-1b.
我们报告一例因母胎人类血小板抗原(HPA)-1不相容导致的新生儿同种免疫性血小板减少症。在母体血清中可检测到抗HPA-1b抗体。用高剂量免疫球蛋白反复治疗婴儿可使血小板计数暂时有效升高,但该患者血小板减少持续超过6周。血清学和DNA分析显示,母亲为HPA-1a纯合子,父亲为HPA-1b纯合子。
