Epidemiological Profile of Chronic Hemodialysis Patients in Ouagadougou

Abstract

Goal: By describing the epidemiology of chronic hemodialysis patients in the single hemodialysis unit of Burkina Faso, we want to contribute to the prevention and improvement of chronic renal failure management (CRF) in this country. Patients and Methods: A descriptive cross-sectional study was conducted in the hemodialysis unit of the University Hospital Center Yalgado Ouedraogo (UHC-YO) during the period from February 12 to May 15, 2015. The patients who started hemodialysis in this unit and were treated for at least three months were included in this study. The sociodemographic and clinical data were collected. The statistical significance was defined for a probability (p ≤ 0.05). Results: One hundred and seventy-two patients (71.2% of the 240 patients of the unit) have been included. The sex ratio was 1.6. The average age was 45.2 ± 12.4 years old. The presumed causes of CRF have been identified in 134 cases (77.9%). The most frequent were hypertensive nephropathy (65 cases; 48.5%), chronic glomerulonephritis (41 cases; 30.6%; including 11 viral origin and 16 with history of recurrent otorhinolaryngologic infections and/or urinary schistosomiasis). Hemodialysis began in an emergency context in 118 cases (68.6%). The average duration of hemodialysis was 29.4 ± 28.4 months. Conclusion: The main suspected causes of CRF were hypertension and chronic glomerulonephritis. The origin of the latter seemed more often infectious. Prevention of CRF in Burkina Faso should be focused on that of hypertension and infectious diseases.
