Compromised Renal and Hepatic Functions and Unsteady Cellular Redox State during Preeclampsia and Gestational Diabetes Mellitus.

INTRODUCTION:To assess renal and hepatic functions along with the redox state in preeclampsia (PE) and gestational diabetes mellitus (GDM) pregnancies. DESIGN AND METHOD:The study was conducted on 33 PE (mean age = 30 ± 5 years), 33 GDM (mean age = 30 ± 6 years) and age, gravida, parity, and ethnicity matched 25 normal pregnancies (NP). Biomarkers of redox status, renal and hepatic functions; aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), bilirubin, urea, blood urea nitrogen (BUN), creatinine, uric acid, lipid peroxidation (MDA), total thiols (TSH), radical scavenging activities and ferric reducing antioxidant potentials of serum were measured. RESULTS:Higher urea, BUN, uric acid, creatinine and overexpressed AST, ALT, ALP was observed in PE (p <0.03-p<0.001), whereas in GDM elevation in creatinine and ALT activity were only statistically significant (p <0.01) in comparison to NP. Diminished antioxidant/radical scavenging potentials, TSH content and increased MDA were noted in both the diseased pregnancies when compared with NP with statistically significant variables ranged from p <0.04-p <0.0001. CONCLUSION:Our data suggest that PE has detrimental effects on renal and hepatic functions while GDM are prone to malfunctioned liver and kidney performances. Impaired redox state may be one of the reasons of altered physiological process in PE and GDM pregnancies. Results may be used to monitor the efficiency and efficacy of antioxidant supplementation, recently suggested for PE and GDM patients.
