[Prevalence of chronic renal insufficiency in diabetic type 2 patients based on the estimated glomerular filtration rate and relation with cardiovascular risk.]

Abstract

BACKGROUND AND OBJECTIVE: The aim of this study was: to estimate the prevalence of chronic renal insufficiency (CRI) in diabetic type 2 (DM2) patients treated in Primary Care based on the estimated glomerular filtration rate (GF(e)); to determine associated factors with CRI, and to evaluate the relationship of GF rate and risk of cardiovascular disease. PATIENTS AND METHODS: This was a descriptive cross-sectional study. We included 500 medical histories randomly selected in a total of 2,950 DM2 patients. We registered sociodemographic data, comorbidities, cardiovascular risk factors and laboratory data. CRI definition was based on GF(e) rate and classified according to the K/DOQI Clinical Practice Guidelines for Chronic Kidney Disease. RESULTS: The prevalence of CRI was 23.2%. There were 51.6% females and the mean age was 66.2 years; 70,4% had hypertension and 67% dyslipidemia. The presence of CRI was related with older age, females, smoking habit, plasma creatinine value, microalbuminuria, and history of hypertension, dyslipidemia and cardiovascular disease. After analysing the data according to the category of GF rate, only the significant relationship with smoking habit disappeared. Multivariate statistic analysis supports a relation with older age, female gender, dyslipidemia and heart disease. CONCLUSIONS: We confirm a high prevalence of CRI in DM2 patients and their relationship with the presence of cardiovascular disease.
