Insights
Pregnancies after kidney transplants resulted in many preterm births and lower birth weights. However, children showed no major defects or kidney issues, though breastfeeding was not advised due to medication.
Area of Science:
- Nephrology
- Obstetrics
- Pediatrics
Background:
- Renal transplant recipients face unique challenges during pregnancy.
- Understanding pregnancy outcomes in this population is crucial for maternal and infant health.
Purpose of the Study:
- To evaluate the outcomes of pregnancies in women who have received kidney transplants.
- To assess the health and development of infants born to renal transplant recipients.
Main Methods:
- Retrospective study of 113 pregnancies in 72 renal transplant recipients.
- Analysis of delivery methods, gestational age, birth weight, Apgar scores, and congenital defects.
- Long-term follow-up of children for renal function and development.
Main Results:
- High incidence of preterm delivery (64%) and lower birth weights observed.
- Vaginal delivery in 28%, Cesarean section in 72%.
- Low incidence of congenital defects; no significant renal or developmental issues found in 41 children up to 52 months, despite maternal cyclosporine exposure.
Conclusions:
- While pregnancies in renal transplant recipients often result in preterm birth and low birth weight, infants generally have good outcomes.
- Long-term follow-up indicates no significant renal abnormalities or developmental delays in children exposed to cyclosporine in utero.
- Breastfeeding is not recommended due to the presence of cyclosporine in maternal milk.
Abstract:
We studied 113 pregnancies in 72 renal transplant recipients. The mean duration between the transplant operation and the first pregnancies was 19.9 months (1-72). This paper focuses on the findings in babies and their outcome. The male babies were 34% of the total. 28% of the babies were delivered vaginally and 72% by Caesarian section. It was noted that there was high incidence of preterm delivery in 64% of the pregnancies. The birth weights were also less than that observed in the general population. 84% was under 50th percentile for weight with 19% being under the 10th percentile. (Saudi growth chart, KACST) The mean hospital stay was 18 days (2-44). The Apgar score was less than 7 in only 10% of the cases and 10 in 50.9%. The incidence of congenital defects was low and no different than the general population (we encountered only 4 cases with minor defects). Despite exposure to cyclosporine throughout the pregnancy and having reduced Nephron mass by virtue of their low birth weight we could not find any glomerular or tubular defects, hypertension or prorienuria in 41 children with a mean age of 52 months. We advised against breast feeding in view of the presence of cyclosporine in the mothers' milk.
