Summary
Hepatitis E, typically reversible, can become chronic and lead to cirrhosis in immunocompromised patients. This review covers recent findings on Hepatitis E virus (HEV) infection in these individuals.
Area of Science:
- Hepatology
- Virology
- Immunology
Context:
- Hepatitis E virus (HEV) infection historically associated with epidemics in tropical/subtropical regions.
- Genotypes I and II caused epidemics; genotypes III and IV linked to sporadic cases in Western countries.
- Previously considered self-limiting, except in pregnant women, with severe outcomes.
Purpose:
- To review recent literature on Hepatitis E in immunocompromised patient populations.
- To highlight the altered disease course and complications of HEV in these individuals.
- To discuss current therapeutic and preventive strategies for Hepatitis E.
Summary:
- Immunosuppression transforms Hepatitis E into a chronic condition, potentially leading to liver cirrhosis.
- HEV infection in immunocompromised hosts can manifest with extrahepatic, often autoimmune, complications.
- Focus on solid organ transplant recipients, HIV-infected individuals, and chemotherapy patients.
Impact:
- Underscores the need for vigilance and tailored management of Hepatitis E in immunocompromised patients.
- Informs clinical practice regarding diagnosis, monitoring, and treatment of chronic HEV.
- Highlights the potential for severe liver disease and extrahepatic manifestations in specific patient groups.

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...
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...
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...
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...
Diseases of the Liver and Gallbladder
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

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...
