Severe gestational (incidental) thrombocytopenia: To treat or not to treat

Abstract

Thrombocytopenia is common in pregnancy and is diverse in etiology. Immune thrombocytopenic purpura (ITP) may affect both mother and the newborn. Gestational (incidental) thrombocytopenia in an otherwise fit woman, at term is the most frequent type of thrombocytopenia and poses no clinical consequences for mother or infant. We report six women who presented with severe thrombocytopenia during pregnancy. Five were treated in late pregnancy, either with intravenous immunoglobulin (IVIg), or IVIg followed by steroids. There was no response, and four received a platelet transfusion during delivery. The platelet counts in all the infants were normal and the maternal thrombocytopenia resolved spontaneously after delivery in all cases. Our observations suggest that this is a group of patients with a severe form of gestational thrombocytopenia. The severe form of gestational thrombocytopenia appears to be rare, and recognition is important, as it may recur in subsequent pregnancies and does not require any therapeutic intervention.
