Immune response in fulminant viral hepatitis, type B
Gastroenterology
|October 1, 1976
Summary
In fulminant hepatitis B, declining hepatitis B surface antigen (HBsAg) levels were observed before death. This viral hepatitis study found no detectable antibody to surface antigen (anti-HBs).
Area of Science:
- Hepatology
- Virology
- Immunology
Background:
- Fulminant hepatitis B is a severe form of viral hepatitis B infection.
- Understanding the immune response and viral kinetics in fatal cases is crucial for clinical management.
Observation:
- Serial serum samples from three patients with fatal hepatitis B were analyzed.
- Hepatitis B surface antigen (HBsAg) titers decreased significantly before death.
- Antibody to HBsAg (anti-HBs) was undetectable throughout the fatal course.
Findings:
- The observed HBsAg decline suggests a potential, albeit insufficient, host response.
- Antibody to core antigen (anti-HBc) and "e" antigen/antibody patterns were non-specific.
- A rise in alpha-fetoprotein indicated late, inadequate liver regeneration.
Implications:
- These findings highlight distinct serological profiles in fatal hepatitis B cases.
- The lack of anti-HBs suggests impaired antibody production in fulminant disease.
- Further research into immune evasion strategies in severe hepatitis B is warranted.

B Cell Activation and Differentiation
14.4K
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Immune Response Against Viral Pathogens
2.4K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Hypersensitivity Reactions: Cytolytic Reactions
208
Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...

Hepatitis
86
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.

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...
