The 2024 updated WHO guidelines for the prevention and management of chronic hepatitis B: Main changes and potential implications for the next major liver society clinical practice guidelines.

Progress towards global elimination of hepatitis B virus (HBV) has been slow and most countries are far from reaching the elimination targets set out by the World Health Organization (WHO). The burden of chronic hepatitis B is mainly borne by resource-limited countries where only a minority of people living with HBV are diagnosed and treated and international guidelines are hardly applicable in real-life. In March 2024, the WHO released its revised guidelines for the prevention and management of chronic hepatitis B. Simplification of care and expansion of treatment criteria represent the core of this revision. Whether and how these updated WHO guidelines will influence the next hepatitis B recommendations from the international liver societies (EASL, AASLD and APASL) remain uncertain. Yet, the European, American and Asian regions encompass multiple low, middle and intermediate-income countries with high HBV endemicity and vulnerable populations that should benefit from simplified clinical algorithms. Here, from an analysis of the WHO guideline development process and its new recommendations, we aimed to identify the anticipated areas of agreement and controversies with the next liver society hepatitis B guidelines, which will have to balance clinical risks and benefits for patients.
