BackgroundSuccessful pregnancy outcomes in patients with advanced chronic kidney disease (CKD) are increasingly common in Western countries. However, in Korea, the available literature addressing this clinical issue is scarce.MethodsWe reviewed 5 successful parturitions [1 patient with Stage 5 CKD and 4 with maintenance hemodialysis (HD)] at Seoul St. Mary's Hospital over 3 years and investigated changes in dialysis prescription, anemia management, and the incidence of maternal and neonatal complications.ResultsThere were no maternal or neonatal deaths in this cohort. The mean age at the time of conception and delivery was 35.8 ± 3.7 and 36.2 ± 3.5 years, respectively. Dialysis patients received more frequent and intensified HD during pregnancy, 20.0 ± 5.7 h/wk of HD over 5 visits with the ultrafiltration dose maintained between 1 and 2 kg per session. All patients received erythropoietin-stimulating agents and iron replacement therapy during pregnancy. The mean hematocrit was 33.1 ± 1.9% before pregnancy and was well maintained during gestation (33.9 ± 3.8% at the first trimester, 29.2 ± 4.2% at the second trimester, and 33.6 ± 8.7% at delivery). The mean gestation period was 32.7 ± 4.7 weeks, with 60% of patients experiencing premature delivery. The primary maternal complication was pre-eclampsia; 3 women developed pre-eclampsia and underwent emergency cesarean sections. Most neonatal complications were related to preterm birth.ConclusionDialysis-related care and general clinical management improved the clinical outcome of pregnancy for patients with advanced CKD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
