[MIRA study: epidemiology of microalbuminuria in type 2 diabetes patients and associated comorbidities]. / Enquête mira: épidémiologie de la microalbuminurie et des comorbidités associées chez le diabétique de type 2.

UNLABELLED: This is an observational survey screening for microalbuminuria in diabetes patients type 2. This survey takes place during the general practioner (GP) consultation in Rhône-Alpes area. It is preliminary survey. Five hundred and sixty three patients were included, consecutively, during the same week, by 185 GP. They were aged from 18 to 80 years and previously research for microalbuminuria was carried out at least one year ago. A questionnaire collecting data concerning age, weight, height, diabetic vintage and HbA1c, arterial pressure, renal function, associated risk factors as (lipids, tabacco, cardiovascular history personal and family, antihypertensive diabetic and lipid treatments. Microalbuminuria as well as urine creatinine was detected with a dipstick to calculate albumin-creatinine ratio. Patients aged 64.66 +/- 11.23, 55% were male; 51% had a microalbumuniria between 30 mL/L and 300 mL/L, but if one consider the albumin-creatinine ratio 59% had a microalbuminuria. In these patients, the diabetes history is longer and body mass index >30 is more frequent 35 vs 27%. HbA1c is similar in the two groups of patients, but patients with microalbuminuria had more often two treatments. Regarding hypertension, there are no difference between the two groups in term of blood pressure control and there is no correlation between blood pressure and albuminuria level. Nevertheless 68% of the patients were uncontrolled for blood pressure. Renal impairment (creatinine clearance <60 mL/min) was present in 26% of the whole group but more frequent in microalbuminuria patients 30 vs 23%. IN CONCLUSION: prevalence of microalbuminuria seems to be higher in this population compared to data previously reported and linked to the vintage of the diabetes mellitus. Comorbidities as well as risk factors were more frequent in patients with microalbuminuria.
