Autoimmune Liver and Gastric Diseases
A complete solution for the diagnosis of gastric and liver autoimmune diseases.
Autoimmune liver and gastric diseases involve the immune system attacking components of the gastrointestinal (GI) tract, leading to chronic inflammation and tissue damage. These disorders can affect different organs, including the intestines, liver, pancreas, and biliary system. Common examples include , autoimmune hepatitis, primary biliary cholangitis, autoimmune atrophic gastritis and inflammatory bowel diseases. Persistent inflammation may lead to complications including fibrosis, strictures, malabsorption, and organ dysfunction. Diagnosis typically combines clinical evaluation, imaging, histology, and detection of disease-specific circulating autoantibodies.
What are the most prevalent Gastric and Liver Autoimmune pathologies?
The identification and the discrimination of autoantibodies against parietal cells (APCA), mitochondria (AMA), liver-kidney microsome type 1 (LKM-1), and smooth muscle (ASMA), ensure highly valuable medical insights in a cost-efficient manner.
The combination of gastroscopy and determination of specific autoantibodies is needed for the diagnosis of gastric and hepatic autoimmune diseases:
- Autoimmune gastritis is characterized by progressive atrophy of the gastric mucosa, reduced gastric acid secretion, and impaired production of intrinsic factor. APCA is an advantageous tool for screening for autoimmune atrophic gastritis (AAG) and pernicious anemia (PA). PA is a direct consequence of vitamin B12 defective absorption in the small intestine, leading to reduced red blood cell production and enlarged, immature erythrocytes.
- AMA are the typical biomarkers of primary biliary cholangitis (PBC), being present in 90–95% of patients. PBC is a chronic autoimmune liver disease characterized by progressive destruction of the small intrahepatic bile ducts, leading to cholestasis and eventual liver damage.
- ASMA are a specific diagnostic marker for Autoimmune Hepatitis Type 1 (AIH-1), being present in almost 70% of the patients.
- LKM-1 are directed against the enzyme cytochrome P450 2D6, most commonly associated with Autoimmune Hepatitis Type 2 (AIH-2 ) and occasionally detected in some cases of chronic hepatitis C infections.
Autoimmune hepatitis is a leading cause of chronic liver inflammation that can progress to liver cirrhosis and liver failure if left untreated.
1.3
million people worldwide are estimated to live with AIH
1.5
million people worldwide are estimated to live with PBC
90%
of the cases of pernicious anemia are linked to AAG
