Sequential therapy with lamivudine followed by interferon-alfa (IFN-alpha) shows promise for chronic hepatitis B treatment. However, further research is needed to confirm its long-term benefits and viral suppression efficacy.

Area of Science:

Hepatology
Virology
Pharmacology

Background:

Investigating various combination and sequential therapies for chronic hepatitis B using nucleoside/nucleotide analogues (NAs) and interferon-alfa (IFN-alpha).
Evaluating the efficacy of dual NA therapy and combined NA and IFN-alpha therapy in achieving viral suppression.

Discussion:

Combination therapies of two NAs or IFN-alpha and NAs have not yet achieved superior viral suppression.
Sequential therapy, specifically lamivudine followed by IFN-alpha, demonstrates a potentially better sustained virologic response.

Key Insights:

Dual NA therapy and combined NA/IFN-alpha therapy are insufficient for enhanced viral suppression in chronic hepatitis B.
Sequential NA and IFN-alpha treatment, particularly lamivudine then IFN-alpha, offers a promising strategy for sustained virologic response.

Outlook:

Further long-term studies are required to fully define the beneficial effects of sequential lamivudine and IFN-alpha therapy.
Exploring optimal sequencing and duration of antiviral treatments for chronic hepatitis B is crucial for long-term patient outcomes.
