Prevalence of hepatitis B surface antigen among hemodialysis patients from Middle Eastern countries: a systematic review and meta-analysis

Abstract

Aim: The aim of this study was to determine the overall prevalence of hepatitis B surface antigen (HBsAg) among hemodialysis patients reported from the Eastern Mediterranean Regional Office of the WHO (EMRO) countries and the Middle East. Methods: Several databases such as PubMed, ISI Web of Science, MEDLINE and Scopus were searched for publications reporting HBsAg prevalence among hemodialysis patients up to December 2016. Results: From all the samples, the pooled prevalence of HBsAg was estimated (95% CI) to be 4.4% (4.4–4.5%). Conclusion: The prevalence of HBsAg in hemodialysis units in the Middle Eastern countries is decreasing over the recent years. Nevertheless, it is important to conduct more studies in these regions to achieve more representative results.
