Abstract
The epidemiology of hepatitis B virus (HBV) and hepatitis C virus (HCV) is important for health planners and service providers. A cross‐sectional study was conducted to investigate the seroprevalence and associated risk factors for markers of HBV (HBsAg) and anti‐HCV among hemodialysis patients at the Ahmed Gasim hemodialysis unit, Sudan. Structured questionnaires were used to obtain socio‐demographic data and sera were tested for hepatitis B surface antigen (HBsAg) and antibody to HCV (anti‐HCV). Of the 353 patients enrolled in the study, HBsAg and anti‐HCV were detected in 16 (4.5%) and 30 (8.5%) patients, respectively. None of the patients were co‐infected with HBV and HCV. Multivariate analysis showed that duration of dialysis was significantly associated with anti‐HCV seropositivity [OR = 1.1, 95% CI = 1.2–1.3; P = 0.024]. No other socio‐demographic or clinical characteristics (age, sex, level of education, history of surgery, and number of units of blood transfused) were significantly associated with HBsAg or anti‐HCV seropositivity. The results of this study suggest that HBsAg and anti‐HCV have low prevalence among hemodialysis patients in Khartoum. Longer duration of dialysis was a risk factor for anti‐HCV. J. Med.
