Neonatal Alloimmune Thrombocytopenia and Neutropenia Associated With Maternal Human Leukocyte Antigen Antibodies PEDIATRIC BLOOD & CANCER Gramatges, M. M., Fani, P., Nadeau, K., Pereira, S., Jeng, M. R. 2009; 53 (1): 97-99

Abstract

Neonatal thrombocytopenia or neutropenia may result from passive transfusion of maternally derived antibodies. Antibodies against platelet antigens are commonly associated with neonatal alloimmune thrombocytopenia (NAIT), and anti-neutrophil antibodies are frequently identified in alloimmune neonatal neutropenia (ANN). Combined alloimmune cytopenias in the newborn are rarely reported; even fewer reports document human leukocyte antigen (HLA) antibodies as a potential cause of neonatal thrombocytopenia or neutropenia. We describe neutropenia and thrombocytopenia in a newborn associated with markedly elevated maternal HLA antibodies in the absence of anti-neutrophil or anti-platelet antibodies to highlight consideration of HLA antibodies in the pathogenesis of ANN and NAIT.
