¿Es la cirrosis biliar primaria una enfermedad del complejo inmunológico?
Lancet (London, England)
|December 17, 1977
Resumen
Los grandes complejos inmunes activan el complemento en la cirrosis biliar primaria, causando potencialmente daño tisular. Estos complejos pueden vincular la enfermedad hepática con otras afecciones sistémicas.
Área de la Ciencia:
- Inmunología Inmunología.
- Hepatología Hepatología.
- Patología Patología Patología.
Sus antecedentes:
- La cirrosis biliar primaria (CBP) se caracteriza por la destrucción de los conductos biliares mediada por el sistema inmunológico.
- Se detectan grandes complejos inmunes en la circulación de los pacientes con CBP.
- Estos complejos activan la vía clásica del complemento.
Objetivo del estudio:
- Para investigar el papel de los grandes complejos inmunes en la patogénesis de la cirrosis biliar primaria.
- Explorar el vínculo potencial entre la formación del complejo inmune intrahepático y las manifestaciones extrahepáticas de la CBP.
Principales métodos:
- Análisis de la presencia y el tamaño del complejo inmunológico en la circulación del paciente.
- Evaluación de las vías de activación del complemento.
- Examen histopatológico del tejido hepático para la deposición del complejo inmunológico y las lesiones asociadas.
- Correlación de los hallazgos intrahepáticos con las enfermedades autoinmunes extrahepáticas.
Principales resultados:
- Se confirman grandes complejos inmunológicos en la circulación de los pacientes con CBP.
- La evidencia sugiere que estos complejos activan la vía clásica del complemento.
- La histopatología revela lesiones granulomatosas alrededor de los conductos biliares y vasculitis consistente con lesión del complejo inmunológico.
- Las afecciones asociadas como la artritis reumatoide están potencialmente relacionadas con los complejos inmunológicos sistémicos.
Conclusiones:
- Los grandes complejos inmunes están implicados en la patogénesis de la cirrosis biliar primaria.
- Se postula la formación de complejos inmunes cerca de los conductos biliares, posiblemente de antígenos absorbidos.
- Los complejos inmunológicos sistémicos pueden contribuir a las enfermedades extrahepáticas asociadas con la CBP.

Autoimmune Disorders
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

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...

Cirrhosis I: Introduction
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Chronic Pancreatitis II: Pathophysiology
Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
