title: [Effect of pre-existing hypertension on the prevalence and incidence of microalbuminuria in non insulin-dependent diabetic patients].
abstract: Microalbuminuria predicts increased rate of hypertension and mortality in insulino-dependent diabetics. In non insulin-dependent diabetes, hypertension often exists before onset of diabetes. To study effects of preexisting hypertension on prevalence and occurrence of elevated urinary albumin excretion (UAE), we collected datas from 614 non insulin-dependent diabetics, in a cross sectional survey: age was 60 +/- 10.4 years, (range 40-75 years), body mass index (BMI) 29 +/- 5.8 kg/m2, hemoglobin A1C 8 +/- 1.9%, systolic blood pressure (SBP) 134 +/- 18 mmHg, diastolic blood pressure (DBP) 76 +/- 10 mmHg, and serum creatinine 91 +/- 44 mumol/l. In the whole group, prevalence of hypertension was 59%. Microalbuminuria (EUA 20-200 mg/l) was present in 25.9% of the cases, microalbuminuria (EUA greater than 200 mg/l) in 7.5%. Cases with hypertension existing before or at onset of diabetes were 243 (HT group), cases without hypertension at onset were 371 (non HT group). In HT group, prevalence of microalbuminuria in increasing class of duration of diabetes were: 31% (0-4 years), 25% (5-9 years), 35% (10-14 years), 21% (15-19 years). Prevalence of macroalbuminuria was respectively: 3%, 11%, 15% and 4%. In the non HT group, microalbuminuria was present in 14% of the cases (0-4 years), 24% (5-9 years), 30% (10-14 years), 25% (15-19 years); prevalences of macroalbuminuria were: 1%, 8%, 6%, 15%. Mean values of UAE, compared to values of the class 0-2 years, were significantly higher in class 12-14 years (32.3 +/- 8 vs 14.4 +/- 3.7 mg/l; p = 0.02] in the HT group.(ABSTRACT TRUNCATED AT 250 WORDS)
