Abstract
Objective
To report pregnancy outcomes for women with kidney transplantation and investigate whether different intervals after transplantation have different effects on pregnancy outcomes.
Methods
A single-center retrospective study was performed. Based on intervals after transplantation, pregnant women with kidney transplantation are divided into two groups: intervals <5 years and ≧5 years. The maternal and neonatal outcomes were compared between the two groups.
Results
No maternal and neonatal deaths occurred. The average age of mothers during pregnancy was 32.3 ± 4.1 years and they had a functioning transplant for 4 (interquartile ranges, 3, 6) years. Preeclampsia occurs in sixteen (16.5 %) pregnancies and gestational diabetes (GDM) occurs in twenty (20.6 %). Eighty-eight newborns (90.7 %) had a gestational age of <37 weeks. The average gestational age for live births was 33.8 ± 2.2 weeks and the average birth weight was 2285.6 ± 581.8 g. Neonatal respiratory distress syndrome (NRDS) occurs in fifty-one babies (52.6 %), intraventricular hemorrhage (ICH) occurs in twenty-nine (29.8 %), atrial septal defects (ASD) occurs in thirty-two (32.9 %) and bronchopulmonary dysplasia (BPD) occurs in seven (7.2 %). Further analysis, pregnancy results, including pre-eclampsia, hypertension or GDM, did not differentiate between the two groups (intervals <5 years vs. ≧5 years). Neonatal outcomes, including premature delivery, low birth weight, mode of birth, small for gestational age (SGA), RDS, ICH, ASD, BPD were not distinguishable between the two groups (intervals <5 years vs. ≧5 years). The level of neonatal blood creatinine after birth was linearly related to high maternal creatinine, and can drop to normal levels within a week.
Conclusions
The incidence of maternal and neonatal complications in pregnancies following kidney transplantation is still high, despite the success of most pregnancies. Various posttransplant intervals had no significant impact on pregnancy outcomes.
期刊介绍：
Established as an authoritative, highly cited voice on early human development, Early Human Development provides a unique opportunity for researchers and clinicians to bridge the communication gap between disciplines. Creating a forum for the productive exchange of ideas concerning early human growth and development, the journal publishes original research and clinical papers with particular emphasis on the continuum between fetal life and the perinatal period; aspects of postnatal growth influenced by early events; and the safeguarding of the quality of human survival.
The first comprehensive and interdisciplinary journal in this area of growing importance, Early Human Development offers pertinent contributions to the following subject areas:
Fetology; perinatology; pediatrics; growth and development; obstetrics; reproduction and fertility; epidemiology; behavioural sciences; nutrition and metabolism; teratology; neurology; brain biology; developmental psychology and screening.
