[Pregnancy in patients with renal transplantation].
From 1969 to 1987, 35 pregnancies occurred in 31 women with renal transplant. Four of them were still pregnant when this study was concluded. There was one ectopic pregnancy. All patients received azathioprine and prednisone. In the majority of patients the glomerular filtration rate increased in a way similar to normal pregnant women. In five cases there was a progressive loss in renal function. In four of them this was attributed to preexistent renal damage. No toxemia occurred. Anemia developed during 11 pregnancies and blood transfusion was required for five women. Four patients had urinary tract infection which was easily controlled with antibiotics. One patient had severe arterial hypertension, secondary to chronic rejection. One patient developed jaundice reverted with reduction in azathioprine doses. One woman died of septicemia secondary to fetal death, during the 6th month of pregnancy. Twenty children were born with no abnormalities, although many of them were underweighted. Two thirds of pregnancies were delivered by cesarean section. No harm to the pelvic allograft occurred in vaginal deliveries. There have been 4 abortions (2 of them were induced with no medical indication). Four pregnancies (26 to 39 gestational weeks) ended in stillborn babies: the mothers had impaired renal function associated with hypertension and proteinuria. One newborn died of pulmonary infection two days after delivery. Another was born with microcephaly and polydactilia and survived 6 years. No breast feeding was allowed.
