Effect of pregnancy on graft function and graft survival in renal cadaver transplant patients

Variable experience is documented for pregnancy in renal transplant patients. Furthermore, little information is available that compares graft function and graft survival of cadaver transplant patients who undergo pregnancy with those of a similar group of patients who do not undergo pregnancy. From 1970 to 1979, 30 patients of childbearing age were identified who were first-time recipients of cadaver-donor kidneys. Long-term follow-up was from 32 to 136 months. Five patients have undergone seven pregnancies that resulted in six viable infants and one therapeutic termination. Pregnancy complications included severe preeclampsia, spontaneous premature rupture of membranes, and proteinuria. One infant was small for gestational age. There were no neonatal problems, and no congenital anomalies. Rejection episodes were more common in the postpartum than in the antepartum period (four of six versus one of six). Chronic rejection that led to graft loss occurred in two patients. Ten patients who did not undergo pregnancy were identified for comparison of graft function and graft survival. Late graft rejections occurred in four patients, two of whom eventually suffered graft loss. Survival rates of the grafts by actuarial analysis for the two groups were not significantly different.
