Resumen
La hepatitis crónica inmunomediada en perros se presenta sutilmente, a menudo diagnosticada excluyendo otras causas e identificando la hepatitis de interfaz. El tratamiento inmunosupresor temprano ofrece el mejor pronóstico para la hepatitis canina.
Área de la Ciencia:
- Medicina Veterinaria Interna
- Hepatología canina
- Inmunopatología
Sus antecedentes:
- La hepatitis crónica inmunomediada es una causa frecuente de enfermedad hepática crónica en perros.
- Los signos clínicos, los resultados de laboratorio y las imágenes a menudo no son específicos, y muchos perros son subclínicos desde el principio.
- El diagnóstico requiere excluir otras etiologías hepáticas y reconocer hallazgos histopatológicos específicos.
Objetivo del estudio:
- Revisar el enfoque de diagnóstico de la hepatitis crónica mediada por el sistema inmunológico en perros.
- Discutir las estrategias de tratamiento actuales y sus efectos adversos asociados.
- Hacer hincapié en la importancia del diagnóstico y la intervención tempranos para obtener resultados óptimos.
Principales métodos:
- El trabajo de diagnóstico implica la exclusión de diagnósticos diferenciales como la toxicosis por cobre, la exposición a fármacos/toxinas, las infecciones y la neoplasia.
- El examen histopatológico es crucial, siendo la hepatitis de interfaz una característica clave.
- El tratamiento suele incluir agentes inmunosupresores como la ciclosporina, el micofenolato o los corticosteroides.
Principales resultados:
- Las presentaciones clínicas variables y los hallazgos diagnósticos no específicos complican el reconocimiento temprano de la enfermedad.
- La hepatitis de interfaz en la biopsia de hígado es un sello distintivo de la hepatitis crónica mediada por el sistema inmunológico.
- La terapia inmunosupresora es la piedra angular del tratamiento y requiere una cuidadosa consideración de los efectos secundarios.
Conclusiones:
- El diagnóstico precoz y el tratamiento de la hepatitis crónica inmunomediada en perros conducen a un pronóstico generalmente bueno a excelente.
- El manejo proactivo es esencial para mitigar la progresión de la enfermedad y optimizar los resultados del paciente.
- La investigación en curso sobre nuevos enfoques terapéuticos puede mejorar aún más el tratamiento a largo plazo de la hepatitis canina.

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:24Chronic Pancreatitis I: Introduction
147
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:25Immunodeficiency Diseases
1.2K
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.

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
264
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
