Introduction: Chronic kidney failure is an independent risk factor of cardiovascular disease. Its association with carotid atherosclerosis remains controversial. The purpose of our study was to assess the factors associated with carotid atherosclerosis specially the components of chronic kidney disease., Methods: In a cross-sectional study, we enrolled type 1 or type 2 diabetic patients from the endocrinology an diabetology department of the military hospital of Rabat assigned in two groups according to the presence or absence of carotid atherosclerosis. Kidney function was assessed based on albuminuria and the estimated glomerular filtration rate calculated using the "modification of diet in renal disease" equation. A multiple logistic regression analysis was performed to identify independent factors associated with carotid atherosclerosis., Results: One hundred and six diabetic patients were enrolled including 96 type 2 diabetic patients. Age (P<0.001), diabetes duration (P=0.04), hypertension (P=0.002), peripheral arterial disease (P<0.001) and chronic kidney failure (P=0.001) were significantly associated with carotid atherosclerosis. After adjusting for age, hypertension, diabetes duration and peripheral arterial disease, chronic kidney failure was an independent factor associated with carotid atherosclerosis (OR: 5.46; 95%IC: 1.29-23.01; P=0.021)., Conclusion: Our data suggest that chronic kidney failure is associated with carotid atherosclerosis in diabetic patients independently of the common cardiovascular risk factors., (Copyright © 2016 Elsevier Masson SAS.
