Achieving a cure for chronic hepatitis B virus (HBV) infection is challenging due to the virus's resilience and weak immune responses. New antiviral strategies aim to improve treatment efficacy and achieve a durable cure.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Chronic hepatitis B virus (HBV) infection is a significant global health concern.
- Current treatments often fail to eradicate HBV due to challenges in disrupting viral DNA and insufficient immune responses.
- Novel therapeutic approaches are essential for achieving a functional cure.
Purpose of the Study:
- To review current and emerging treatment regimens for chronic hepatitis B.
- To highlight strategies targeting the HBV lifecycle and host immune system.
- To discuss the potential for finite treatment durations and durable cures.
Main Methods:
- Literature review of available and investigational antiviral agents.
- Analysis of treatment strengths, limitations, and mechanisms of action.
- Exploration of immunomodulatory strategies.
Main Results:
- Current first-line treatments rarely achieve complete HBV eradication.
- New agents target various stages of the HBV lifecycle.
- Combination therapies and immunomodulation show promise.
Conclusions:
- Developing new antiviral agents is crucial for effective chronic hepatitis B treatment.
- Targeting both the virus and the host immune response is key.
- Future strategies aim for a finite treatment course and a functional, durable cure.
