RESUMO
Total 193 diabetic patients were investigated to assess the prevalence of microalbuminuria. Urinary albumin excretion rate (UAER) was measured by radioimmunoassay (RIA) on 3 hours urine samples. The prevalence of microalbuminuria (UAER) > 15 micrograms/min was 41%. Microalbuminuria was commonly observed in patients having diabetes for more than 5 years. A significant correlation was found between duration of diabetes and microalbuminuria (p < 0.01). Glycemic control (fasting and postprandial blood sugar) did not show any correlation with UAER, whereas blood urea (r.39, p < 0.01), creatinine (r.26, p < 0.05) and chloride (r.24, p < 0.05) were positively correlated. A significant correlation was found between raised blood pressure and UAER (p < 0.01).
