Microalbuminuria in NIDDM patients in south India.
Urinary albumin excretion (UAE) was estimated by radioimmunoassay in 316 non-insulin dependent diabetic patients (NIDDM), with diabetes for 10 or more years and proteinuria less than 150 mg/24 h. Albuminuria was determined in 24 h collection of urine in 259 patients but in the other 57, a random sample was used. The mean UAE was 23 +/- 45.3 (SD) micrograms/mg creatinine in the patients against 4.4 +/- 2.7 micrograms/mg in the controls (30). Ninety patients (28.5%) had microalbuminuria i.e., the UAE exceeded, 20 micrograms/mg creatinine. A higher percentage (31.7%) of men had microalbuminuria than women (23.6%). The presence of microalbuminuria was similar in the insulin-treated and in oral drug-treated patients (29.6% and 26.5% respectively). Stepwise multiple regression analysis using albumin/creatinine ratio as the dependent variable showed that factors such as blood pressure, blood glucose, HbA1, body mass index, sex, age, duration of diabetes and the association of vascular complications of diabetes did not have significant correlation to microalbuminuria. Creatinine clearance showed a significant inverse correlation to the albumin/creatinine ratio. Although the prevalence of microalbuminuria in NIDDM in this study is not significantly different from those reported from other countries, the morbidity index due to kidney disease could be high due to the large absolute number involved in our country. This underscores the need for early detection of the disease and institution of preventive measures to arrest its progression.
