[Microalbuminuria in patients with type 2 diabetes].

OBJECTIVE To identify microalbuminuria in patients with type 2 diabetes. MATERIAL AND METHODS A descriptive cross-section study was made in patients with type 2 diabetes with more than a year of evolution. Microalbuminuria was defined as the presence of 30 to 300 mg of albumin in urine of 24 hours. The socio-demographic characteristics, type of diet, exercise, type of antihypertensive and oral antihyperglycemic agents were analyzed. Basal glycemia after one and two months, and renal state were assessed. RESULTS Of 301 type 2 diabetic patients, 251 had microalbuminuria. The mean age was 57.2 years old. Women predominated over men (1.4:1). The mean for diabetes evolution was nine years. The complication with more frequency was hypertensive cardiopathy 78.1 %. A medium protein diet was present in 49%. 62.2% exercised and 40.2% exercised less than 30 minutes. Mean GFR with creatinine clearance was 83.3 +/- 32 mL/min. 98% of the cases received oral antihyperglycemic agents. Basal glycemia, after one and two months, was, on average, 171.8 mg/dL, 190.1 mg/dL, and 217.4 mg/dL. 74.5% of the patients had hyperglycemia in the first measuring, 79.3% in the second one, and 70.5% in the third one. CONCLUSIONS The prevalence of microalbuminuria was greater than the reported in literature (85.3%). A poor control of glycemia was showed.
