Prevalence of Diabetic Nephropathy among Patients of Type 2 Diabetes at Tertiary Care Hospital Lahore

Abstract

Background: Diabetic nephropathy is a significant complication of Type 2 Diabetes Mellitus, often leading to chronic kidney disease (CKD) and potentially progressing to End-Stage Renal Disease (ESRD). Approximately 90% of individuals with diabetes and hypertension may develop ESRD in the later stages of the disease. Objective: The study aimed to determine the prevalence of diabetic nephropathy among patients with type 2 diabetes at a tertiary care hospital in Lahore. Methods: This retrospective study included 100 reports from the chemical pathology and microbiology laboratory at Fatima Memorial Hospital, Lahore, covering renal function tests (RFT) such as Urea, Blood Urea Nitrogen (BUN), Creatinine, and estimated Glomerular Filtration Rate (eGFR), as well as HbA1c levels and Albuminuria. Data collection involved accessing electronic medical records (EMRs) to obtain comprehensive clinical data, including patients' medical history, duration of diabetes, glycemic control measurements, blood pressure, and prescribed medications. The study included patients with type 2 diabetes and kidney disease, excluding those without renal disease. Ethical approval was obtained from the Institutional Review Board (IRB) of FMH College of Medicine and Dentistry, adhering to the principles of the Declaration of Helsinki. Data were analyzed using IBM SPSS version 25, with categorical variables expressed as frequencies and percentages and continuous variables as mean ± standard deviation (SD). Correlation analysis was conducted, with a p-value of less than 0.05 indicating statistical significance. Results: The study included 100 participants, with 53% being male and 47% female. The mean age was 59.19 years (SD = 18.812), ranging from 18 to 91 years. Albuminuria was present in 88% of participants. Elevated serum creatinine was observed in 93%, HbA1c levels >6.4% in 68%, high urea levels in 87%, and eGFR <60 in 14%. Correlation analysis showed a significant positive correlation between HbA1c and eGFR (Spearman's rho = 0.432, p < 0.001) and between urea and serum creatinine (Spearman's rho = 0.701, p < 0.001). Conclusion: The high prevalence of albuminuria and elevated renal function markers among individuals with type 2 diabetes underscores the importance of early detection and comprehensive management. Regular screening for urinary albumin, stringent glycemic control, and optimal blood pressure management are crucial for preventing the progression of diabetic nephropathy.
