Background Diabetes is the leading cause of chronic kidney disease worldwide. Diabetic kidney disease is one of the microvascular complications of diabetes and it involves changes in glomerular hemodynamics, interstitial fibrosis, and tubular atrophy. Early detection and management of Diabetic kidney disease (DKD) help to reduce morbidity and mortality. This study aims to assess the prevalence of nephropathy and albuminuria in the diabetic population attending an Irish tertiary care center. Methods Retrospective data collection and analysis of patients diagnosed with Type 1 diabetes mellitus (T1DM) and Type 2 diabetes mellitus (T2DM) through the Development and Integration of Accurate Mathematical Operations in Numerical Data-Processing (DIAMOND) database in a single Irish tertiary care center. An audit tool was used to collect patients' information including gender, age, type of diabetes, serum creatinine, urinary albumin excretion, albumin creatinine ratio (ACR), body mass index, and last available glycated hemoglobin (HbA1c). Results Out of 7394 subjects with T2DM, 3139 (42%) were identified with chronic kidney disease (CKD). There were 1866 subjects with positive ACR out of 3139 subjects with CKD in the T2DM cohort. This shows that 25% of subjects have diabetic kidney disease and 17% have CKD of undetermined etiology. In the T1DM cohort with 1166 subjects, 209 (18%) were identified with CKD. Out of these 209 subjects with CKD, 164 (14%) were ACR-positive. The prevalence of CKD and albuminuria were related to age in both T1DM and T2DM populations. Albuminuria showed a linear relationship with age in subjects with no known CKD, which shows that age causally relates to albuminuria independent of type and duration of diabetes. Conclusion CKD is more prevalent in patients with T2DM as compared to T1DM, whereas the prevalence of albuminuria is higher in the T1DM population.
