Primary autoimmune thrombocytopenia in pregnancy: maternal and neonatal outcomes

Aim: To evaluate clinical characteristics, maternal and neonatal outcomes among pregnant women with primary autoimmune thrombocytopenia (ITP). Materials and methods: All pregnant women with ITP who had undergone antenatal follow-up and delivery at the Department of Obstetrics and Gynecology at a referral center, between 2011 and 2021, were retrospectively investigated. Patients were evaluated in three groups according to antenatal treatment modality. Results: 42 pregnant women with ITP were included in the study. A total of 29 (%69) pregnant women had been diagnosed with ITP before pregnancy and 13(%31) were diagnosed during pregnancy. 17 (%41) pregnant women did not receive any antenatal treatment, and 25 (%59) pregnant women receieved treatment. Postpartum haemorrhage (%50) was reported more frequently in the steroids+IVIG group. A total of 42 pregnancies, 43 babies (one twin pregnancy, 41 singletons) were liveborn. Three neonates (%7) had thrombocytopenia and one of them had intracranial haemorrhage. Conclusions: In pregnancies complicated with ITP, the platelet count is moderately or severely low, which can have adverse maternal and neonatal outcomes. Postpartum haemorrhage is a significant cause of maternal morbidity in cases with ITP. Therefore, pregnant women with ITP should be delivered in facilities that can adequately manage postpartum haemorrhage.
