A Case of Neonatal Alloimmune Neutropenia Associated with Anti-Human Neutrophil Antigen-1a (HNA-1a) Antibody
Neonatal alloimmune neutropenia (NAN) is an uncommon disease of the newborn provoked by the maternal production of neutrophil-specific alloantibodies, whereby neutrophil IgG antibodies cross the placenta and induce the destruction of fetal neutrophils. Affected newborns are usually identified by the occurrence of bacterial infections. The most frequent antigens involved in NAN are the human neu...
متن کاملAnti-Human Platelet Antigen-1a Immunoglobulin G Preparation Intended to Prevent Fetal and Neonatal Alloimmune Thrombocytopenia
Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a severe disease that is caused by maternal alloantibodies generated during pregnancy or at delivery as a result of incompatibility between maternal and fetal human platelet antigens (HPAs) inherited from the father. Antibody-mediated immune suppression using anti-HPA-1a immunoglobulins is thought to be able to prevent FNAIT caused by HP...
متن کاملResistance to recombinant human granulocyte colony-stimulating factor in neonatal alloimmune neutropenia associated with anti-human neutrophil antigen-2a (NB1) antibodies.
Neonatal alloimmune neutropenia is the neutrophil counterpart of the erythrocyte disorder of hemolytic disease of the newborn. Fetal neutrophil antigens, which are inherited from the father but foreign to the pregnant mother, provoke the formation of maternal antibodies, which, on transplacental passage, cause fetal/neonatal neutropenia. Because infants with this disorder are at a higher risk o...
متن کاملGranulocyte Antibodies in Korean Neonates with Neutropenia
Neonatal alloimmune neutropenia (NAN) is a disease that can cause severe and prolonged neutropenia in neonates. However, no report is available on the incidence of granulocyte antibody in neonates, the target antigen of this antibody, and the estimated incidence of NAN in Korea. Among a total of 856 neonates admitted to a neonatal intensive care unit (NICU) over a five year period, a total of 1...
متن کاملA Case of Neonatal Neutropenia Due to Anti-Fc Gamma Receptor IIIb Isoantibodies Treated with Recombinant Human Granulocyte Colony Stimulating Factor
Alloimmunization to granulocyte-specific antigens can occur during pregnancy. Maternal antibodies of IgG class can cross the placenta to result in alloimmune neonatal neutropenia. Antibodies to human neutrophil antigens anti-HNA-1a, HNA-1b, and HNA-2a have been most commonly reported to cause alloimmune neonatal neutropenia. Isoantibodies to Fc gamma RIIIb (CD16) if mother is a HNA-null phenoty...
