Abstract

Hepatitis B virus (HBV) reactivation poses a significant clinical challenge, especially in patients undergoing immunosuppressive therapies, including monoclonal antibody treatments. This manuscript briefly explores the complex relationship between monoclonal antibody therapy and HBV reactivation, drawing upon current literature and clinical case studies. It delves into the mechanisms underlying this phenomenon, highlighting the importance of risk assessment, monitoring, and prophylactic measures for patients at risk. The manuscript aims to enhance the understanding of HBV reactivation in the context of monoclonal antibody therapy, ultimately facilitating informed clinical decision-making and improved patient care. This paper will also briefly review the definition of HBV activation, assess the risks of reactivation, especially in patients treated with monoclonal antibodies, and consider management for patients with regard to screening, prophylaxis, and treatment. A better understanding of patients at risk can help clinicians provide optimum management to ensure successful patient outcomes and prevent morbidity.

Keywords: Hepatitis B virus, Reactivation, Acute infection, Chronic infection, Monoclonal antibodies

Core Tip: Reactivation of hepatitis B (HBV) induces a rapid and acute increase in viral replication in a patient with chronic HBV infection or prior HBV exposure. There is also an increased risk of HBV reactivation in patients treated with monoclonal antibodies. Organ damage can be due to various mechanisms and risk factors that activate the cascade of inflammatory responses, such as direct infection. It is of clinical importance to diagnose, manage, and treat individuals, especially those at risk. Patient outcomes, success of therapy, prevention of complications, and management of existing comorbidities depend on the correct multidisciplinary management in patients at risk.
