Hepatitis B remains a significant yet preventable health issue in South Africa. The introduction of the hepatitis B vaccine into the country some 18 years ago has demonstrated benefit, but the exposure to, and prevalence of chronic HBsAg positivity remain unacceptably high. Those with chronic hepatitis B virus infection have an elevated risk of developing cirrhosis with end-stage liver disease and a markedly elevated risk of hepatocellular carcinoma, independent of the presence of cirrhosis. The challenge in South Africa remains prevention through the universal vaccination coverage of all children and the identification of those with chronic hepatitis B virus infection. Over the last decade our understanding of hepatitis B and its behaviour and natural history in those with chronic infection has significantly improved. This understanding is key to identifying those who warrant further evaluation and therapy. A number of global societies have updated their guidelines in recent years. This document draws on these guidelines and serves to contextualise, for South Africa, practice guidelines for the management of chronic hepatitis B.
乙型肝炎在南非仍然是一个重大但可预防的健康问题。18 年前,乙型肝炎疫苗在该国的引入证明了其益处,但慢性 HBsAg 阳性的暴露和流行仍然高得不可接受。慢性乙型肝炎病毒感染者发生肝硬化和终末期肝病的风险增加,且发生肝细胞癌的风险明显增加,而与肝硬化的存在无关。南非面临的挑战仍然是通过为所有儿童普遍接种疫苗和发现慢性乙型肝炎病毒感染者来预防。在过去的十年中,我们对乙型肝炎及其在慢性感染者中的行为和自然史的理解有了显著提高。这种理解是确定需要进一步评估和治疗的人的关键。近年来,许多全球协会都更新了他们的指南。本文借鉴了这些指南,并为南非的慢性乙型肝炎管理实践指南提供了背景。
