Impact of early chronic kidney disease on maternal and fetal outcomes of pregnancy

Background. Elevated serum creatinine is associated with higher maternal and fetal risks; however, the influence of milder degree of renal impairment diagnosed on basis on estimated glomerular filtration rate (eGFR) is less well defined. This study assesses the impact of early chronic kidney disease (CKD) utilizing eGFR in predicting adverse outcomes in women with CKD.Methods. We analyzed outcomes of 98 pregnant women with CKD. Women with CKD stage 1 were used as control.Results. Women with eGFR of 60–89 ml/min were at an increased risk for deterioration of renal function, preeclampsia, and cesarean section. The odd ratios for composite maternal complication of worsening of renal function or preeclampsia were 6.75 (95% confidence interval (CI), 1.84–24.80) in women with eGFR of 60–89. Similarly, women with an eGFR of 60–89 had a significantly increased risk for intrauterine growth restriction (38.5%), preterm birth (31.2%), and intrauterine fetal death (15.8%). The odds for composite fetal adverse outcome...
