Insights
New guidelines aim to eliminate chronic hepatitis B (HBV) in Latin America by simplifying diagnosis and expanding treatment. These updates focus on improving vaccination and screening to reduce liver disease and cancer rates.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Chronic hepatitis B virus (HBV) infection is a leading cause of cirrhosis and liver cancer globally, particularly in Latin America.
- Despite effective vaccines, HBV remains underdiagnosed and undertreated in the region due to healthcare access challenges.
Purpose of the Study:
- To present updated Latin American Association for the Study of the Liver (ALEH) guidelines for HBV elimination, aligning with WHO targets.
- To simplify HBV diagnosis, broaden treatment eligibility, and enhance vaccination strategies in Latin America.
Main Methods:
- Recommending rapid diagnostic tests and reflex HBV DNA testing to improve access.
- Promoting non-invasive methods for assessing liver disease severity.
- Expanding antiviral therapy criteria to include patients with significant fibrosis, elevated HBV DNA, and co-infections.
Main Results:
- Guidelines emphasize preventing mother-to-child transmission via universal screening, maternal prophylaxis, and neonatal vaccination.
- Universal testing for hepatitis delta virus (HDV) in HBV-infected individuals is advised.
- The recommendations support broader access to antivirals like TDF, TAF, and ETV.
Conclusions:
- Updated ALEH guidelines call for decentralization, simplification, and equity in HBV management.
- These strategies are crucial for achieving HBV elimination goals in Latin America by 2030.
- Addressing diagnostic and treatment barriers is essential for public health in the region.
Abstract:
Chronic hepatitis B virus (HBV) infection remains a major cause of cirrhosis and hepatocellular carcinoma worldwide, with substantial public health implications in Latin America. Despite the availability of an effective vaccine, HBV continues to be underdiagnosed and undertreated across the region, where healthcare access is often limited and heterogeneous. In alignment with the World Health Organization's 2024 strategy for HBV elimination, the Latin American Association for the Study of the Liver (ALEH) presents updated regional guidelines to simplify diagnosis, expand treatment eligibility, and improve vaccination coverage. The recommendations emphasize the use of rapid diagnostic tests and reflex HBV DNA testing to overcome barriers to laboratory access, while promoting non-invasive methods to assess liver disease severity. Expanded treatment criteria include patients with significant fibrosis, elevated HBV DNA levels, co-infections, and other risk factors, ensuring broader access to antiviral therapy with tenofovir disoproxil fumarate (TDF), tenofovir alafenamide (TAF), or entecavir (ETV). Preventing mother-to-child transmission through universal screening, maternal prophylaxis, and timely neonatal vaccination is prioritized. Additionally, universal HDV testing in HBV-infected patients is recommended. These guidelines highlight the urgent need for decentralization, simplification, and equity in HBV management to achieve elimination goals in Latin America by 2030.
