• Background Studies among pregnant Asian women with chronic kidney disease (CKD) have not been widely performed; therefore, clinical criteria for these patients have not been well established. Methods We conducted a retrospective study among pregnant women with CKD who received prenatal care at our institution for 8 consecutive years. Primary outcome was the development of severe adverse events (SAEs). We analyzed correlations between primary outcome and CKD parameters [age, body mass index (BMI), estimated glomerular filtration rate (eGFR), urinary protein–creatinine ratio (UP), systolic blood pressure (SBP), diastolic blood pressure (DBP), and not normal blood pressure (non-NBP)] at the time of referral. Secondary outcomes were low birth weight (LBW), preterm delivery (PreD), and small for gestational age (SGA). We divided into two categories, CKD stage G1, and G2 or higher according to eGFR, and proteinuria negative and proteinuria positive according to UP, respectively. Results We observed 89 pregnancies. SAE was observed in 28 pregnancies. In live birth cases, there were 28 PreD, 28 LBW and 13 SGA. Major SAEs included preeclampsia, superimposed preeclampsia, unscheduled cesarean section, neonatal intensive care unit admission, and fetal death. Stepwise logistic regression analysis selected eGFR (OR = 0.847, p  = 0.026), SBP (OR = 1.897, p  = 0.006) and proteinuria positive (OR = 2.96, p  = 0.046) as the significant predictors of SAEs. There were no significant differences among the baseline characteristics stratified by SGA. Conclusions This is the first study to report pregnancy outcomes among Japanese non-disease-oriented patients with CKD. In Asians, especially in the Japanese population, kidney function, blood pressure and proteinuria might affect pregnancy outcomes.
