Tacrolimus as basic immunosuppression in pregnancy after renal transplantation. A single-center experience.

Renal transplantation restores fertility within an average of 6 months, so women of childbearing age are able to consider pregnancy. Successful pregnancies have been reported in recent years under different immunosuppressive regimens, but the optimal treatment to achieve the maximum safety for both the mother and fetus remains unclear. Tacrolimus has been demonstrated to provide long-term immunosuppression and prevent rejection in most renal transplants. It seems safe, but experience is limited compared with cyclosporine. We report our experience highlighting the high rate of successful pregnancies attained in women treated with tacrolimus as the basic immunosuppressant and advised of recommendations to achieve a healthy newborn. Renal function was preserved during the pregnancy. The puerperal period and the rate of gestation-related difficulties appeared similar to that of the general population.
