OUTCOME OF TWIN PREGNANCY IN A RENAL TRANSPLANT RECIPIENT TREATED WITH TACROLIMUS

Abstract

Our report describes the outcome of a twin pregnancy in a woman who was maintained on tacrolimus after a living related renal transplant. Both babies born at 32 weeks of gestation developed severe respiratory distress requiring ventilator assistance and went on to develop congestive heart failure. Echocardiograms on both babies showed dilated heart chambers. Twin A succumbed to complications, but twin B, who was treated more aggressively with vasopressors, recovered. Autopsy findings on twin A revealed a thrombotic cardiomyopathy with degeneration of cardiac muscle. We believe that the unusual outcome in this set of twins may have been a result of cardiomyopathy secondary to tacrolimus used by the mother during her pregnancy.
