Seroprevalence of human immunodeficiency virus, hepatitis B and C viruses among haemodialysis patients in two newly opened centres in Cameroon.

INTRODUCTION: Haemodialysis (HD) patients are potentially susceptible to infection with blood borne viral agents especially; Human Immunodeficiency Virus (HIV), hepatitis B (HBV) and hepatitis C Viruses (HCV), compared to the general population. We described their epidemiology in two newly created haemodialysis units in Cameroon: the Buea and Bamenda haemodialysis centres.

METHODS: A cross sectional study: included were patients who had spent at least three months in haemodialysis. HBV, HCV and HIV serologies were determined and patients' characteristics extracted from patient's records.

RESULTS: We included 104 participants (44 in Buea and 60 in Bamenda). Mean age was 48 years and 65.4% were men. Median duration in dialysis was 14 months. One of the three viral markers was present in 40.1% of patients. The hepatitis B surface antigen, anti-HCV and anti-HIV antibody prevalence were respectively 10.6%, 19.2%, 13.5%. A history of sexually transmitted infection was the only variable associated with anti-HIV antibody positivity.

CONCLUSION: The sero-prevalence of HBsAg, HCV and HIV are high in the two centres. HIV prevalence may have reflected its etiology as a cause of ESKD. HCV remains a cause for concern and needs further evaluation. There is urgent need for the implementation of preventive and control measures.
