Core Tip

Core Tip: Hepatitis B virus (HBV) reactivation poses a substantial clinical challenge, demanding a nuanced understanding of immunological mechanisms for effective management. This comprehensive review navigates the intricate landscape of HBV reactivation, spotlighting the delicate balance between host immune responses and viral factors. Emphasis is placed on the roles of T cells, natural killer cells, and antigen-presenting cells in disease progression, alongside the repercussions on severity, hepatic flares, liver fibrosis, and hepatocellular carcinoma. Critical analysis of management strategies, spanning anti-viral and immunomodulatory approaches, informs evidence-based practices. Prophylactic anti-viral therapy’s role during immunosuppression and the potential of innovative immunotherapies are explored, contributing significantly to informed disease management and improved patient outcomes.
