Objective The purpose of this study was to evaluate whether maternally administered intravenous immunoglobulins(IV-IG)and intrauterine platelet transfusions(IUPT)for fetal /neonatal alloimmune thrombocytopenia(FNAIT)affect the development of the fetal immune system.Study design The lymphocyte subset distribution of m ononuclear cells of cord blood of 20FNAIT newborns was analyzed by flowcytometry and compared with a control group of healthy newborns and a reference group treated with intra uterine erythrocyte transfusions(IUET)for hemolytic disease.Results The percentage of monocytes,natural ki ller(NK)cells,ratiosof mature and immature T cells and B ce lls,and resting or activated cells were not significan tly different compared to the control group.In addition,the B -cell and Tcell populations showed a normal in vitro antibody production and T -cell proliferation when compared with the control group.Conclusion Antenatal treatm ent for FNAIT with maternal IVIG with or without IUPT is not associated with lymphocyte activation or premature maturation of the neonatal immune system.
