Summary
Autoimmune hepatitis is an immune disorder affecting the liver, diagnosed by autoantibodies and liver inflammation. Treatment with corticosteroids and azathioprine is effective but often requires long-term management due to high relapse rates.
Area of Science:
- Hepatology
- Immunology
- Internal Medicine
Context:
- Autoimmune hepatitis (AIH) is a chronic liver disease of unknown cause.
- It affects all age groups, with a higher prevalence in females.
- Presentation varies from asymptomatic to acute liver failure.
Purpose:
- To outline the diagnostic criteria for autoimmune hepatitis.
- To describe the classification of AIH based on autoantibody profiles.
- To review current treatment strategies and management challenges.
Summary:
- Diagnosis relies on elevated serum gammaglobulins, specific autoantibodies (ANA, SMA, LKM1), and liver biopsy findings (inflammation, necrosis).
- AIH is classified into Type 1 (ANA/SMA positive) and Type 2 (LKM1 positive), with mixed forms also recognized.
- Standard treatment involves corticosteroids and azathioprine, achieving remission but often leading to relapse upon discontinuation.
Impact:
- Distinguishing AIH from other hepatitis types is crucial for appropriate therapy.
- Long-term management requires careful monitoring due to frequent relapses (80%) and potential side effects.
- Discontinuation of therapy may be considered after achieving sustained remission (≥2 years) with minimal residual inflammation.

01:25Hepatitis
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...

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
01:28Viral 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...
01:29Autoimmune 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.

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
