The aim of this report is to evaluate whether pregnancy is a risk factor for poor outcome of infection with hepatitis C virus or for allograft deterioration among kidney transplant recipients. The first case was in a 41-year-old pregnant kidney transplant recipient with hypercreatinemia and a history of toxic hepatitis. The second case was treated with interferon before transplant. Tacrolimus-based immunosuppressive regimens were used during the pregnancies. Hypertension complicated both pregnancies, and the pregnancies ended with cesarean delivery at preterm and term with healthy but low-weight newborns. The first patient became positive for hepatitis C virus RNA after pregnancy without a flare in transaminase level. Antibodies to hepatitis C virus were negative in the newborns. In conclusion, pregnancy should be promoted for kidney recipients infected with hepatitis C virus who have stable graft and liver function.
