Abstract

Aim: The purpose of our study is to compare pregnancy outcomes between women with a functioning renal transplant and women with end-stage renal disease (ESRD). Methods: We carried out a population-based retrospective cohort study using the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from 2006 to 2011. Logistic regression analysis was used to estimate the age-adjusted effect of functioning renal transplant vs. ESRD requiring dialysis on pregnancy outcomes. Results: We identified 264 birth records to women with a functional renal transplant and 267 birth records to women with ESRD on dialysis among 5,245,452 births. As compared to women with ESRD on dialysis, renal transplant recipients were less likely to have placental abruption [odds ratio, OR 0.23 (95% confidence interval, CI 0.08–0.70)], to receive blood transfusions [OR 0.17 (95% CI 0.09–0.30)], and to have growth-restricted and small-for-gestational-age babies [OR 0.45 (95% CI 0.23–0.85)]. Renal transplant recipients were more likely to have an instrumental delivery [OR 15.38 (95% CI 1.92–123.3)]. Among renal transplant women, there was a trend towards delivery by cesarean section as compared to patients with ESRD [OR 1.31 (95% CI 0.93–1.85)]. However, these results were not statistically significant. Fetal deaths were less likely to occur in women with a renal transplant [OR 0.41 (95% CI 0.17–0.96)]. There were four maternal deaths among patients with ESRD on dialysis and no maternal deaths among renal transplant patients. Conclusion: Patients with a functional renal graft had an overall lower rate of morbidity and adverse pregnancy complications when compared to patients with ESRD on dialysis.
