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.

Introduction. The purpose of this preliminary study is to describe the clinical, paraclinical, and evolutionary profiles of gold miner patients with kidney failure hospitalized in the nephrology and haemodialysis service in the Yalgado Ouédraogo University Hospital of Ouagadougou (CHU-YO). Patients and Methods. This was a longitudinal and descriptive study with a retrospective collection of data for the period from February 1, 2013, to March 31, 2018. Included were all gold miner patients who stayed and worked at an artisanal gold mining site for at least three months and who were diagnosed with acute or chronic kidney failure during hospitalization in the nephrology service. We collected sociodemographic, clinical, and paraclinical variables at admission and then three months later. Results. We included 50 patients; all were male and the average age was 29.4 ± 7.7 years. All patients were exposed to mercury and/or cyanide for an average of 4.5 ± 2.8 years. The average consultation/referral time for patients at the CHU-YO was 25.4 ± 14.9 days. The average of creatininemia was 2338.0 ± 791.4 μmol/L. Kidney failure was acute in five cases (10%) and chronic in the remaining 45 cases or 90%. Extrarenal purification was indicated in 43 cases (86%). It was not performed in nine of the 43 cases due to lack of financial resources for patients (six cases) or death prior to the onset of haemodialysis (three cases). Thirty-two of the 50 patients in the study (64% of cases) died. Conclusion. Chronic kidney failure in gold miners appears to be common and late-managed. A prospective study of kidney disease and its causes at gold mining sites and surrounding areas will assess the extent of the problem in the country and better clarify the prevention of these diseases in our country.
