The immunologic profile of infants born after maternal immunoglobulin treatment and intrauterine platelet transfusions for fetal/neonatal alloimmune thrombocytopenia

, : The immunologic profile of infants born after maternal immunoglobulin treatment and intrauterine platelet transfusions for fetal/neonatal alloimmune thrombocytopenia. American Journal of Obstetrics and Gynecology 191(3): 815-820

Objective: The purpose of this study was to evaluate whether maternally administered intravenous immunoglobulins (IVIG) 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 mononuclear cells of cord blood of 20 FNAIT newborns was analyzed by flow cytometry and compared with a control group of healthy newborns and a reference group treated with intrauterine erythrocyte transfusions (IUET) for hemolytic disease. Results: The percentage of monocytes, natural killer (NK) cells, ratios of mature and immature T cells and B cells, and resting or activated cells were not significantly different compared to the control group. In addition, the B-cell and T-cell populations showed a normal in vitro antibody production and T-cell proliferation when compared with the control group. Conclusion: Antenatal treatment for FNAIT with maternal IVIG with or without IUPT is not associated with lymphocyte activation or premature maturation of the neonatal immune system.
