Abstract
Hepatitis B virus (HBV) reactivation is a clinically significant challenge in disease management. This review explores the immunological mechanisms underlying HBV reactivation, emphasizing disease progression and management. It delves into host immune responses and reactivation’s delicate balance, spanning innate and adaptive immunity. Viral factors’ disruption of this balance, as are interactions between viral antigens, immune cells, cytokine networks, and immune checkpoint pathways, are examined. Notably, the roles of T cells, natural killer cells, and antigen-presenting cells are discussed, highlighting their influence on disease progression. HBV reactivation’s impact on disease severity, hepatic flares, liver fibrosis progression, and hepatocellular carcinoma is detailed. Management strategies, including anti-viral and immunomodulatory approaches, are critically analyzed. The role of prophylactic anti-viral therapy during immunosuppressive treatments is explored alongside novel immunotherapeutic interventions to restore immune control and prevent reactivation. In conclusion, this comprehensive review furnishes a holistic view of the immunological mechanisms that propel HBV reactivation. With a dedicated focus on understanding its implications for disease progression and the prospects of efficient management strategies, this article contributes significantly to the knowledge base. The more profound insights into the intricate interactions between viral elements and the immune system will inform evidence-based approaches, ultimately enhancing disease management and elevating patient outcomes. The dynamic landscape of management strategies is critically scrutinized, spanning anti-viral and immunomodulatory approaches. The role of prophylactic anti-viral therapy in preventing reactivation during immunosuppressive treatments and the potential of innovative immunotherapeutic interventions to restore immune control and proactively deter reactivation.
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.
