Comparative efficacy and safety of pegylated interferon-alpha monotherapy vs combination therapies with entecavir or tenofovir in chronic hepatitis B patients

This study investigates how different treatments for chronic hepatitis B (CHB), a widespread liver infection, compare in effectiveness and safety. By evaluating the use of pegylated interferon-alpha alone and in combination with two other drugs, entecavir and tenofovir disoproxil fumarate (TDF), researchers found that TDF offers better viral suppression but also comes with more side effects. For patients receiving TDF combined with PEG-IFN therapy, low HBsAg levels, elevated alanine aminotransferase levels, and lower APRI scores were associated with a higher likelihood of achieving HBsAg loss. Consistent with previous findings, this study confirms the benefits of nucleos(t)ide analog plus PEG-IFN therapy for CHB treatment and further explores which patients are more likely to benefit from combination therapy. Furthermore, this study underscores the importance of further monitoring adverse events in patients receiving combination therapy.
