title: [Screening for microalbuminuria in diabetic patients in the primary health care system].
abstract: In order to detect the prevalence of microalbuminuria, a screening procedure was carried out in 1016 adult (age > 14 years) diabetic patients registered in primary health care system at the 17st district of the capital. The clinical characteristics of patients were investigated and microalbuminuria was measured by immunoturbidimetric method using first void morning urinary samples. In this way, the urinary albumin/creatinine ratio was calculated (abnormal value in men > or = 2.5 mg/mmol, in women > or = 3.5 mg/mmol). Moreover, serum creatinine, blood glucose, serum cholesterol and triglycerides were measured in fasting blood samples. After applying exclusion criteria data of 933 diabetic patients [129 insulin-dependent (IDDM) and 804 non-insulin-dependent (NIDDM) patients; 424 men, 509 women] were analysed. Abnormal urinary albumin/creatinine ratio was found in 315 (33.8%) patients. Microalbuminuria was detected in 32 (24.8%) IDDM and in 201 (25.0%) NIDDM patients. Macroalbuminuria was found in 13 (10.1%) IDDM and in 69 (8.6%) NIDDM patients. Abnormal urinary albumin/creatinine ratio was more often found in men than in women (IDDM men 41.3%, IDDM women 28.8%; NIDDM men 38.0%, NIDDM women 30.0%). Significant difference was found between diabetic patients with (n = 315) and without (n = 618) abnormal urinary albumin/creatinine ratio regarding age (64.3 +/- 0.7 years vs. 61.4 +/- 0.5 years; p < 0.001), duration of diabetes (10.3 +/- 0.5 years vs 7.9 +/- 0.3 years; p < 0.001) systolic blood pressure (151 +/- 1 mmHg vs 146 +/- 1 mmHg; p < 0.01), serum creatinine (99 +/- 2 mumol/l vs 88 +/- 1 mumol/l; p < 0.001) and blood glucose (10.4 +/- 0.2 mmol/l vs 9.4 +/- 0.1 mmol/l; p < 0.001). One third (33.8%) of diabetic patients in primary health care setting exhibited signs or were at risk of renal involvement of diabetes. Diabetic patients with micro- or macroalbuminuria should be carefully controlled in order to prevent or to decrease deterioration of renal function due to diabetic nephropathy.
