Abstract
Introduction: The hemodynamic adjustments during pregnancy play a pivotal role in sustaining the gestation, however, its clinical connotation on midterm renal hyperfiltration and its consequence on maternal and fetal outcomes need a greater appraisal. The present retrospective study looked into the midterm estimated glomerular filtration rate (eGFR) among pregnant females without overt pieces of evidence of chronic kidney disease (CKD) as a surrogate marker for midterm hyperfiltration and its implication on maternal and fetal outcomes. Materials and methods: All pregnancies among females aged 18–50 years with available pregestational baseline serum creatinine were included in the study. Maternal renal hyperfiltration was expressed as the highest eGFR, using the creatinine clearance method. Its association with adverse maternal and fetal outcomes was assessed. Results: A total of 1,045 pregnancies were assessed during the study. According to midterm eGFR, among them, 65% of pregnancies showed midterm eGFR between 120 and 150, however, 4.3% of pregnancies had values more than 150 mL/min per 1.73 m2 . The risk of poor pregnancy outcome was observed for eGFR levels below and above the reference level of 120–150 mL/min per 1.73 m2 (1.97 for values ?150 mL/min per 1.73 m2 , and 1.72 for 90–120 mL/min per 1.73 m2 ). Pregnancies with eGFR between 60 and 90 mL/min per 1.73 m2 had odds ratios (ORs) of 5.64. Conclusion: A distinctive relationship was observed between the midterm eGFR and adverse pregnancy outcomes with the best outcomes for midterm eGFR levels between 120 and 150 mL/min per 1.73 m2 . Despite no apparent functional renal deterioration, a poor maternal hyperfiltration response may play a crucial impact on poor pregnancy outcomes.
