Insights

Hepatitis D virus (HDV) infection significantly increases the risk and severity of chronic hepatitis, severe hepatitis, and liver cirrhosis in patients with hepatitis B (HB). HDV may also inhibit HBV DNA replication and directly harm liver cells.

Area of Science:

  • Hepatology
  • Virology
  • Infectious Diseases

Background:

  • Hepatitis B virus (HBV) infection is a global health concern.
  • Hepatitis D virus (HDV) is a unique satellite virus that requires HBV for replication.
  • Understanding the interplay between HBV and HDV is crucial for managing coinfections.

Purpose of the Study:

  • To investigate the pathogenesis of hepatitis D virus (HDV) infection.
  • To analyze the clinical characteristics and outcomes of patients coinfected with HBV and HDV.
  • To compare the clinical features and laboratory results of HDV-positive and HDV-negative hepatitis B patients.

Main Methods:

  • A comparative analysis of 507 patients with hepatitis B and HDV infection against 213 patients with hepatitis B alone.
  • Evaluation of hepatitis types, prognosis, clinical symptoms, and biochemical markers.
  • Analysis of hepatitis virus serological markers, including HBsAg, HBeAg, and HDAg.

Main Results:

  • HDV coinfection was associated with higher incidence and mortality rates of severe chronic hepatitis, severe hepatitis, and liver cirrhosis.
  • HDV-positive patients exhibited increased rates of bleeding, ascites, hepatic coma, and elevated ALT levels.
  • HDV infection led to a lower detection rate of HBeAg and a higher expression of HDAg, suggesting inhibition of HBV replication.

Conclusions:

  • HDV infection significantly worsens the prognosis of hepatitis B, increasing the risk of severe liver disease.
  • HDV may play a direct cytotoxic role in liver damage and disease progression.
  • HDV coinfection can suppress HBV replication, impacting viral markers like HBeAg.

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...

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...

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency disorders...
