Prevalence of Microalbuminuria in Type 2 Diabetes Mellitus

Objective: The presence of albumin in the urine is a marker of glomerular involvement in type 2 diabetes mellitus (T2DM), depicting diabetic nephropathy. Strict glycemic control can prevent and delay the occurrence of microalbuminuria and other diabetic complications. Therefore, we conducted a study to report the prevalence of microalbuminuria in type 2 diabetics along with its association with diabetic control. Methods: A total of 133 patients with T2DM were consecutively included and their co-morbidities, body mass index, mode of treatment of diabetes (oral hypoglycemic drugs and/or insulin), duration since diagnosis of T2DM, and hemoglobin A1c (HbA1c) levels were recorded. A morning, mid-stream urine sample was collected and a urine spot for albumin:creatinine ratio (UACR) was assessed. Descriptive and analytic statistics were drawn with different variables and UACR values. Results: The mean age of the participants was 54.5 ± 10.3 years which included 60.9% males and 39.1% females. The overall incidence of diabetic nephropathy was 30.1%, with 25.6% having microalbuminuria and 4.5% having macroalbuminuria. Pearson correlation test was used to compare UACR and duration of diabetes (p=0.034) and HbA1c (p=0.001). Conclusion: UACR was higher in patients with uncontrolled T2DM (in terms of higher HbA1c value) and with a longer duration since diagnosis. We recommend that UACR should be inculcated in routine practice, annually, for all patients with T2DM for gauging the development of underlying renal involvement and prompt management.
