Autoantibodies in Autoimmune Hepatitis
Digestive Diseases (Basel, Switzerland)
|December 8, 2015
Summary
Diagnostic autoantibodies are key for diagnosing autoimmune hepatitis. Detecting these markers, like antinuclear antibodies (ANA), aids in confirming probable or definite cases.
Area of Science:
- Hepatology
- Immunology
- Clinical Diagnostics
Background:
- Autoimmune hepatitis diagnosis traditionally relies on detecting specific autoantibodies.
- Key autoantibodies include antinuclear antibodies (ANA), anti-smooth muscle antibodies (SMA), anti-liver/kidney microsomal type 1 (anti-LKM1), anti-liver cytosol type 1 (anti-LC1), and anti-soluble liver antigen (anti-SLA).
Purpose of the Study:
- To emphasize the pivotal role of diagnostic autoantibodies in autoimmune hepatitis diagnosis.
- To highlight the significance of these markers in achieving diagnostic scores for autoimmune hepatitis.
Main Methods:
- Indirect immunofluorescence techniques.
- Immuno-enzymatic assays utilizing recombinant antigens.
Main Results:
- Detection of one or a combination of diagnostic autoantibodies is crucial.
- These autoantibodies contribute to diagnostic scores for probable or definite autoimmune hepatitis.
Conclusions:
- Diagnostic autoantibodies (ANA, SMA, anti-LKM1, anti-LC1, anti-SLA) are fundamental for diagnosing autoimmune hepatitis.
- Ancillary autoantibodies may have clinical correlations but require assay validation and are often institution-specific.

Gastritis-II: Pathophysiology
1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Hepatitis
34
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.

Autoimmune Disorders
2.2K
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.

Antigens Involved in Adaptive Immunity
1.8K
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.
