[Prevalence of microalbuminuria in French type 2 diabetics followed by their general practitioner].
Microalbuminuria is a risk marker for cardiovascular morbidity and mortality in Type 2 diabetes. We studied microalbuminuria among French Type 2 diabetic patients in general practice, because we set-up a trial using cardiovascular events as end-points. Two thousand twenty four volunteer patients were studied for Urinary Albumin Concentration (UAC) during outpatient visit to general practitioners. The UAC was measured on first samples. If UAC was positive (> or = 20 mg/l), a second sample was requested. If UAC was positive two times, persistently elevated UAC was identified (micro or macroalbuminuria). Clinical characteristic, cardiovascular antecedents and risk factors were studied. One hundred five first samples were excluded due to urinary infection; 1,217 others displayed normal UAC (< 20 mg/l); 63.4%; group N), 557 microalbuminuria (20-200 mg/l; 29.0%, group mu), and 145 others macroalbuminuria (> 200 mg/l; 7.6%; group M). Among subjects with positive first sample, 26.5% had persistent albuminuria. There was no intergroup difference for age, but males were more frequent in groups mu or M than N (p < 10(-4)). Blood pressure and body mass index varied between groups. Smokers and alcoholic subjects were more frequent in groups mu and M than N (p = 0.037 and p = 0.0003 respectively), as were cases with myocardial infarction (p = 0.0026), lower limb arteritis (p < 10(-4)), and laser-treated diabetic retinopathy (p = 0.0002). Antihypertensive treatments were taken by 61% of the subjects. Elevated UAC (micro or macroalbuminuria) is frequent among french Type 2 diabetic patients cared by their general practitioners, and is associated with a high cardiovascular risk profile.(ABSTRACT TRUNCATED AT 250 WORDS)
