Epidemiological patterns of chronic kidney disease in black African elders: a retrospective study in West Africa

Abstract

Chronic kidney disease (CKD) is frequently described in elders. This study describes the epidemiological patterns of patients ≥60 years old admitted in our department during one year. The prevalence of CKD was 10.8% (60/552). The mean age of the patients was 70.5 years (60-84 years) and the sex ratio (male:female) was 1.08. The mean serum creatinine level was 7.10 mg/dL (1.31-25.0 mg/dL) and more than two-third of the patients presented CKD stage 4-5. Causes of CKD were dominated by hypertension (30%) and diabetes (25%). Prevalence of inpatients aged 60-69 years old was higher than in those ≥80 years old but lower than that in patients aged 70-79 years. At admission, 83.3% of the patients were hypertensive, 75% were anemic and 13% presented proteinuria. The main co-morbidities associated with CKD were neoplasms (17% of cases), chronic heart disease (15% of cases) and pneumonia (15% of cases). Furosemide was prescribed in 55% of the patients, calcium channel blockers in 23% of the patients and ACE inhibitors in 20% of the patients. Renal replacement therapy was not performed for any patient. Evolution was favorable in the majority of patients (77%), but 23% died mainly because of uremia and infections.
