Complejos inmunológicos circulantes en las hepatitis no A, no B. Posible enmascaramiento del antígeno viral
Lancet (London, England)
|June 16, 1979
Resumen
Se detectaron complejos inmunológicos circulantes en más de la mitad de los pacientes con hepatitis no A, no B asociada a la transfusión. Estos complejos pueden dificultar la detección de antígenos virales, lo que afecta las capacidades de diagnóstico.
Área de la Ciencia:
- Hepatología Hepatología.
- Inmunología Inmunología.
- Virología Virología.
Sus antecedentes:
- La hepatitis no A, no B asociada a la transfusión sigue siendo un desafío de diagnóstico.
- Las técnicas inmunológicas convencionales han enfrentado dificultades en la detección de antígenos virales causantes.
Objetivo del estudio:
- Investigar la presencia y la importancia de los complejos inmunes circulantes en las hepatitis no A, no B.
- Explorar el papel potencial de los complejos inmunes en el enmascaramiento de antígenos virales.
Principales métodos:
- Se analizaron muestras de suero de serie de 22 pacientes y 2 chimpancés.
- Se empleó el radioinmunoensayo de células Raji para detectar complejos inmunes circulantes.
Principales resultados:
- Se identificaron complejos inmunológicos circulantes en el 59% de los pacientes y en 1 chimpancé.
- En los casos crónicos, los niveles complejos fluctuaron con la actividad de la aminotransferasa.
- Los complejos detectados pueden ocultar los antígenos virales, lo que explica las fallas de diagnóstico.
Conclusiones:
- Los complejos inmunes están presentes en una proporción significativa de los casos de hepatitis no A, no B.
- La presencia de complejos inmunes puede ser un factor clave que limita la detección de antígenos virales.
- Se justifica una mayor investigación sobre las interacciones entre el complejo inmunológico y el antígeno viral.

Humoral Immune Responses
Overview
Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

Antibody Actions
Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.

Immune Response Against Viral Pathogens
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...

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...
