Objective: Despite rising incidence of diabetes in India, we currently lack country wide data on the prevalence of CKD in T2DM patients. Hence this nationwide study was planned. Methods: This was a nationwide, cross-sectional, observational, multi-centric study to assess prevalence of CKD among T2DM patients. The primary endpoint of the study was to estimate proportion of T2DM patients with CKD (glomerular filtration rate [GFR] <60 ml/min/1.73 m2or albumin creatinine ratio [ACR] ≥ 30 mg/g or ≥ 3 mg/mmol or both). The blood/plasma and urine samples, were collected for estimation of hemoglobin A1c, microalbuminuria, serum creatinine, urine creatinine, and routine urine analysis. Results: Of the 3043 screened subjects, 3000 eligible subjects were enrolled, out of which 46% were females. The mean age was 53.4 (± 11.9) years, with a mean body mass index of 27.3 (± 4.8) kg/m2. Both micro and macro vascular complications were reported. In the studied population with T2DM, 47.8% had mildly decreased, 15.1% had mild to moderately decreased, and 1.8% had severely decreased GFR respectively. As per ACR categorization, 61.3% had normal to mildly increased ACR, 25.6% with moderately increased and 7.2% with severely increased ACR were seen. We observed a significant (p<0.0001) weak negative correlation (-0.23069) between eGFR< 60 mL/ min/1.73 m² and urinary ACR in over six hundred patients. We found 48.4% prevalence of CKD in T2DM patients. The results on analysis of HbA1c goal achievement showed that the patients without CKD had a better success rate to achieve the target <7% goal of HbA1c compared to those who had CKD (29.6% vs. 23.4%). Conclusion: Study reported higher prevalence of CKD which was driven by the ACR levels and majority of the patients had reasonable eGFR. This can be a guide to select drug and dosage of diabetes drug as it depends on kidney function.
