Serum Biochemical Changes among Chronic Kidney Disease Patients in a Rural Cohort of Odisha, India: A Cross-sectional Study

Introduction: Chronic Kidney Disease (CKD) is one of the fastest-growing causes of death worldwide. Monitoring biochemical parameters such as liver function tests, kidney function tests, and lipid profiles is crucial for early identification of health complications, prevention, and prompt management in CKD patients. Aim: To investigate the association of sociodemographic factors and serum biochemical indicators with Glomerular Filtration Rate (GFR) among CKD patients in rural Odisha, India. Materials and Methods: A cross-sectional study was conducted in a rural cohort of the Model Rural Health Research Unit (MRHRU) established in Cuttack district, Odisha, India, from March 2021 to April 2021. A total of 530 registered CKD patients were enrolled in the study. Sociodemographic data and blood samples were collected for lipid profile, kidney function, and liver function analysis. The data were analysed using STATA 15.1 and RStudio 2021.09.0+351. Results: The mean age of the study participants was 51.2±14.1 years, with 330 (62.26%) being male. A total of 74% of the participants showed abnormal Estimated Glomerular Filtration Rate (eGFR). Abnormal eGFR was found to be more common among the older age group (>45 years), those who were literate, and those in private jobs, compared to their counterparts. Both lipid profile and liver function abnormalities were significantly associated with individuals having normal eGFR. Conclusion: The positive association of eGFR with lipid profile and liver function enzymes highlights the importance of regular screening of these parameters among CKD patients for early prevention and control of future complications.
