Direct-acting antivirals (DAAs) can strongly inhibit the replication of hepatitis C virus (HCV) and effectively clear the infection, but it may cause hepatitis B virus (HBV) reactivation, leading to severe liver damage and fulminate hepatitis in patients with HCV/HBV coinfection. In this review, we summarized the different replication process of HCV and HBV in infected hepatocytes and consequent innate immune response, and then discussed the molecular mechanism and clinical significance of HBV reactivation, and put forward the clinical precaution.

Chronic hepatitis B virus (HBV) infection remains a global health burden. Timely and effective antiviral therapy is beneficial for patients with HBV infection. With existing antiviral drugs, including nucleos(t)ide analogs and interferon-alfa, patients can achieve viral suppression with improved prognosis. However, the rate of hepatitis B surface antigen loss is low. To achieve a functional cure and even complete cure in chronic hepatitis B patients, new antivirals need to be developed. In this review, we summarized the advantages and disadvantages of existing antiviral drugs and focused on new antivirals including direct-acting antiviral drugs and immunotherapeutic approaches.

Chinese Society of Hepatology and Chinese Society of Infectious Diseases, Chinese Medical Association update the guidelines for the prevention and treatment of chronic hepatitis B (version 2022) in 2022. The latest guidelines recommend more extensive screening and more active antiviral treating for hepatitis B virus infection. This article interprets the essential updates in the guidelines to help deepen understanding and better guide the clinical practice.

Hepatitis B virus biomarkers are mainly used in clinical practice to diagnose infection, monitor disease progression, evaluate response to chronic hepatitis B treatment, and evaluate the efficacy of novel antiviral drugs in clinical trials. In combination with the recent research progress of antiviral therapy for chronic hepatitis B and the actual needs of clinical diagnosis and treatment, the expert consensus was formulated by the Cooperative Group of Basic Research and Experimental Diagnosis of Liver Diseases, Chinese Society of Hepatology, Chinese Medical Association. It summarized the evidence and recommended the key points for the clinical application of classic and novel hepatitis B virus related biomarkers in order to guide the standardized and reasonable clinical application for these biomarkers.
