KASL Clinical Practice Guidelines: Management of chronic hepatitis B
Insights
This guideline provides updated strategies for managing chronic hepatitis B (CHB), incorporating new antiviral treatments and addressing antiviral resistance. It offers evidence-based recommendations for diverse patient populations, including special circumstances.
Area of Science:
- Hepatology
- Infectious Diseases
- Clinical Practice Guidelines
Background:
- The Korean Association for the Study of the Liver (KASL) previously issued CHB management guidelines in 2004 and 2007.
- Significant advancements in antiviral therapies and research, particularly concerning antiviral resistance in Korea, necessitate guideline updates.
- New evidence and expert consensus have emerged since the last revision.
Purpose of the Study:
- To present a revised guideline for the management of chronic hepatitis B (CHB).
- To incorporate recent scientific evidence and expert opinions into clinical practice recommendations.
- To address the growing issue of antiviral resistance in CHB management.
Main Methods:
- Development of the guideline based on current evidence and expert consensus.
- Review of recent research findings from Korea and internationally.
- Consideration of specific patient populations and clinical scenarios.
Main Results:
- The guideline targets newly diagnosed and existing CHB patients.
- It provides management guidance for special circumstances including malignancy, transplantation, dialysis, viral coinfections, pregnancy, and pediatric cases.
- Focus on strategies to combat antiviral resistance.
Conclusions:
- The updated KASL guideline offers comprehensive, evidence-based recommendations for CHB management.
- It emphasizes updated strategies for antiviral therapy and resistance.
- Aims to improve patient outcomes in diverse clinical settings.
Unlabelled:
The guideline on the management of chronic hepatitis B (CHB) was first developed in 2004 and revised in 2007 by the Korean Association for the Study of the Liver (KASL). Since then there have been many developments, including the introduction of new antiviral agents and the publications of many novel research results from both Korea and other countries. In particular, a large amount of knowledge on antiviral resistance--which is a serious issue in Korea--has accumulated, which has led to new strategies being suggested. This prompted the new guideline discussed herein to be developed based on recent evidence and expert opinion.
Target Population:
The main targets of this guideline comprise patients who are newly diagnosed with CHB and those who are followed or treated for known CHB. This guideline is also intended to provide guidance for the management of patients under the following special circumstances: malignancy, transplantation, dialysis, coinfection with other viruses, pregnancy, and children.
