Summary
Hepatitis B virus (HBV) reactivation is a serious risk during immunosuppressive therapy, potentially leading to severe liver damage. Preemptive antiviral treatment significantly lowers this risk, improving patient outcomes.
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Hepatitis B virus (HBV) infection persists lifelong, with replication controlled by the immune system.
- Immunosuppressive therapies can disrupt this control, leading to HBV reactivation and severe liver disease.
- HBV reactivation poses significant morbidity and mortality risks across various patient groups.
Purpose of the Study:
- To review the pathogenesis and clinical implications of HBV reactivation.
- To highlight patient populations at risk for HBV reactivation.
- To discuss the role of preemptive antiviral therapy in preventing HBV reactivation.
Main Methods:
- Literature review of HBV pathogenesis and reactivation.
- Analysis of risk factors associated with immunosuppressive treatments.
- Evaluation of preemptive antiviral strategies and outcomes.
Main Results:
- HBV reactivation is immune-mediated, with immunosuppression triggering viral replication flares.
- Corticosteroids and rituximab pose the highest reactivation risk.
- Preemptive nucleos(t)ide analogue therapy effectively prevents HBV reactivation.
Conclusions:
- Identifying at-risk patients via serological markers is crucial.
- Preemptive antiviral therapy, particularly with newer agents like entecavir and tenofovir, is highly effective.
- Tailored antiviral strategies are necessary based on treatment duration and resistance risk.

Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
