Prevalence and risk factors of chronic kidney disease in Cote D'Ivoire: An analytic study conducted in the department of internal medicine

Chronic kidney disease (CKD) has become a public health problem because of its increasing prevalence. The objective of this study was to describe the current profile of CKD in our working conditions. This is a descriptive retrospective study of patients admitted for CKD during the period from January 2010 to December 2014 in the Internal Medicine Department of the university hospital of Treichville in Abidjan. CKD was defined by a glomerular filtration rate below 60 mL/min lasting for at least three months. We collected 252 cases of CKD out of 3573 patients recorded during the study period, yielding a prevalence of 7%. The mean age was 39.6 ± 14 years (15–83 years). We observed a male predominance (sex ratio 1.2:1). Of the CKD patients studied, 67.1% were hypertensive, 7.9% were diabetic, and 8.7% were positive for human immunodeficiency (HIV) virus. The CKD was Stage 3 in 2.4%, Stage 4 in 3.2%, and Stage 5 in 94.4% of the patients. The etiology of CKD was hypertension in 59.9% of cases, followed by chronic glomerulonephritis (25%), HIV infection (9.1%), and diabetes (4.8%). On bivariate analysis, hypertension was the cause of CKD in 48.8% of patients under 35 years, 66.4% in patients between 35 and 64 years, and 85.4% in patients ≥65 years (P = 0.001). Chronic glomerulonephritis was the cause of CKD in 40.2% of patients under 35 years, in 14.3% between 35 and 64 years, and in 4.8% of patients ≥65 years (P = 0.0001). CKD is a common cause of hospitalization in our department. Patients generally consulted at the late stage of the disease. Risk factors are mainly hypertension, HIV infection, and diabetes
