Insights

Hepatitis B virus (HBV), Hepatitis C virus (HCV), and adenovirus were detected in infants with biliary atresia. These viral infections may play a role in the condition

Area of Science:

  • Hepatology
  • Virology
  • Neonatal Research

Background:

  • Biliary atresia is a severe neonatal liver disease with incompletely understood pathogenesis.
  • Viral infections are suspected contributors to biliary atresia development and progression.

Purpose of the Study:

  • To investigate the prevalence of specific viral infections (HBV, HCV, HCMV, adenovirus, BK virus) in neonatal biliary atresia.
  • To determine the potential role of these viruses in biliary atresia-related clinical complications.

Main Methods:

  • Retrospective analysis of 34 formalin-fixed paraffin-embedded (FFPE) liver tissue samples from neonates with biliary atresia.
  • Molecular detection of viral genomes using PCR and RT-PCR.
  • Antigenic detection of HBV, HCV, and HCMV using immunohistochemistry (IHC).

Main Results:

  • HBV, HCV, and adenovirus genomes were detected in 9%, 6%, and 6% of samples, respectively.
  • HBV and HCV co-infection was identified in 6% of FFPE samples.
  • No detection of HCMV or BK virus genomes in the studied liver tissues.

Conclusions:

  • The presence of HBV, HCV, and adenovirus in biliary atresia tissues suggests a potential role in the disease's pathogenesis.
  • Further comprehensive studies are warranted to elucidate the exact contribution of these viral infections to biliary atresia.

Viral Hepatitis I: Introduction01:28

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...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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...
Respiratory Syncytial Virus Disease01:29

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
