The authors tried to clarify relations between autoimmune gastritis and isolated atrophic corpus gastritis by bioptic corporal and antral examinations from 150 probands as well as examinations of gastrin in serum and parietal cell antibody tests. Only 30% of all patients examined with isolated atrophic gastritis of the corpus part revealed criteria of an autoimmune gastritis. Therefore investigations of antibodies against parietal cells are necessary to mark off both clinical pictures. This differentiation seems to be necessary regarding the high risk of gastric cancer following an autoimmune gastritis.

Introduction: Cobalamin deficiency (CD) due to pernicious anemia (PA) leads to hyperhomocystinemia, a risk factor for thrombosis. However, the clinical presentations and outcomes of hyperhomocystinemia-associated thrombosis (HAT) are not fully understood.
Methods: We undertook a literature search using PUBMED, SCOPUS and WEB OF SCIENCE databases for the terms "pernicious anemia AND thrombosis", "pernicious anemia AND embolism", "pernicious anemia AND thromboembolism", "autoimmune gastritis AND thrombosis", "autoimmune gastritis AND embolism", "autoimmune gastritis AND thromboembolism" through January 2024 and reviewed the published literature.

Autoimmune gastritis (AIG) is a chronic inflammatory condition characterized by immune-mediated destruction of gastric parietal cells, leading to oxyntic atrophy, achlorhydria, and hypergastrinemia. While AIG was historically linked to gastric adenocarcinoma and type I neuroendocrine tumors (NETs), recent evidence suggests the risk of adenocarcinoma in AIG is lower than previously believed, particularly in Helicobacter pylori (H. pylori)-negative patients.

Autoimmune gastritis (AIG) is a chronic condition in which the body's immune system mistakenly attacks the stomach lining, specifically targeting parietal cells that produce stomach acid and intrinsic factors. After the infection was eradicated, AIG developed in an elderly woman with symptoms of the disease. 1.

Gastrointestinal T cells (GI-T) play a critical role in mucosal immunity, balancing tolerance and pathogen defence. T cells recognize antigens via T cell receptors (TCRs). Next-generation sequencing (NGS) is utilized to analyse TCR repertoires in contexts such as health, haematological diseases, autoimmunity, and inflammation.

Autoimmune polyglandular syndromes (APS) are characterized by associations of two or more autoimmune diseases (AID). APS type 3 is characterized by the presence of autoimmune thyroid disease associated with other AID, excluding adrenal gland involvement. Here we report a case of a 64-year-old male, with history of type 1 diabetes mellitus (T1DM), diagnosed at the age of 32, who was referred to a Diabetes consultation in 2014 due to poor metabolic control.
