Insights

This study found no link between hepatitis B virus (HBV) genotypes and extrahepatic manifestations in chronic HBV patients. Further research is needed to understand these complex conditions.

Area of Science:

  • Hepatology
  • Virology
  • Immunology

Background:

  • Chronic hepatitis B virus (HBV) infection is a global health concern.
  • Extrahepatic manifestations (EHMs) are common in patients with chronic HBV.
  • The role of HBV genotypes in the development of EHMs remains unclear.

Purpose of the Study:

  • To investigate the correlation between specific hepatitis B virus (HBV) genotypes and the occurrence of extrahepatic manifestations (EHMs) in patients with chronic HBV infection.
  • To identify potential viral or host factors associated with EHMs in this population.

Main Methods:

  • A national, multicenter, retrospective, cross-sectional study was conducted in France.
  • 190 patients with chronic HBV infection (HBsAg-positive for ≥6 months) had their HBV genotypes determined prior to treatment.
  • Clinical and biological extrahepatic manifestations were assessed and correlated with epidemiological, viral, and hepatic factors.

Main Results:

  • Among 190 patients, 16% had clinical EHMs and 15% had biological EHMs. Clinical EHMs were not associated with HBV genotypes but correlated with higher platelet counts.
  • Biological EHMs were associated with anti-HBe antibody positivity and elevated platelet counts.
  • Carriage of precore mutant HBV was linked to an increased risk of biological EHMs.

Conclusions:

  • No association was found between hepatitis B virus (HBV) genotypes and the presence of either clinical or biological extrahepatic manifestations in patients with chronic HBV infection.
  • Platelet count and precore mutant HBV carriage emerged as potential factors associated with EHMs, warranting further investigation.

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...

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...
Genital Herpes01:23

Genital Herpes

Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
