Serological Diagnostic Strategies for Autoimmune Metaplastic Atrophic Gastritis
Background:
The clinical manifestations of AMAG are diverse and easily overlooked. The exact diagnostic criteria for AMAG are yet to be standardized, and serological tests lack clinical practices.
Methods:
This case report demonstrates the process of searching for etiologic agents in a patient with PA.
Results:
Serological tests showed positive APCAs, decreased serum pepsinogen (PG)I, decreased PGI/PGII ratio, and increased serum gastrin (GAS). After supplementation with hematopoietic raw materials such as vitamin B12 and folic acid, the patient recovered well.
Conclusions:
This case report demonstrates a better exploration of serological diagnostic strategies for AMAG.
Insights
Autoimmune metaplastic atrophic gastritis (AMAG) diagnosis can be challenging due to varied symptoms. This case highlights serological tests and nutrient supplementation for effective AMAG management.
Area of Science:
- Gastroenterology
- Immunology
- Clinical Diagnostics
Background:
- Autoimmune metaplastic atrophic gastritis (AMAG) presents with diverse and often overlooked clinical features.
- Standardized diagnostic criteria for AMAG are lacking, and current serological tests are not widely implemented in clinical practice.

01:17Gastritis-II: Pathophysiology
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...
