High-risk pregnancy in beta-thalassemia major women. Report of three cases

Abstract

Reproductive failure is common in beta-thalassemia major patients because of endocrine damage resulting from iron overload. Here 3 full-term pregnancies following spontaneous ovulation in 2 splenectomized beta-thalassemia major women are reported. The main echocardiographic parameters, such as left ventricular end-diastolic and end-systolic diameters, fractional shortening and ejection fraction, were within the normal range before pregnancy, but worsened during gestation, and 1 patient developed pre-congestive heart failure. Deferoxamine therapy was continued throughout 2 pregnancies, while in the other it was stopped after 8 weeks: no abnormalities were noted in the children. Thanks to the currently applied therapies, an increased number of pregnancies may now be expected in beta-thalassemia major women: it is important to find out more about the pregnancy-related problems and their management in these patients.
