Pregnancies following liver transplantation – how safe are they?

Abstract

The number of pregnancies following liver transplantation is increasing due to better patient and graft survival and quality of life. Out of 156 women of a reproductive age, there were 19 pregnancies in 16 women, 12 on CSA and seven on tacrolimus, which occurred between 7/92 and 1/97. The median age of the women was 27.9 yr, median time after transplantation 33 months. There were four spontaneous and two induced abortions in the first trimenon. Ten women delivered ten healthy babies; three newborns had problems (alcoholic embryopathy due to recurrent alcohol abuse of his mother, pneumonia, weight 2000 g). In eight women mostly mild complications were observed, such as hypertension (n = 5), nonspecific elevation of liver enzymes (n = 2), infection (n = 3) and premature labor (n = 1). Mean gestational age was 39 wk and mean birth weight 2900 g. One case of prematurity and three cases of growth retardation occurred. Cesarean sections were performed in 7 patients (54%) for maternal hypertension (n = 2), presumed fetal hypoxia (n = 4) and breech position (n = 1). All children are normally developed, the oldest being 5 yr old. Although experience with tacrolimus is limited, pregnancies following liver transplantation carry an acceptable risk if carefully monitored by an experienced team of transplant surgeons and obstetricians.
