Autoimmune gastritis

Diagnosis of autoimmune gastritis (AIG) is often challenging because of the absence of typical symptoms. Clinical guidelines are lacking, which results in inadequate treatment and poor cancer screening. This work presents an overview of current management options and aims at raising awareness for this disease. The paper also describes a clinical case of the full-scale course of AIG with all its complications. Autoimmune gastritis is mostly considered as a disease of elderly with vitamin B12 deficiency and pernicious anaemia. Today it is recognized that AIG is found with a similar prevalence in all age groups, with iron deficiency being a frequent symptom. Conventional therapy consists of adequate iron and vitamin B12 supplementation, as well as symptomatic approaches. The associated risk for gastric adenocarcinoma and gastric neuroendocrine tumours requires regular endoscopic follow-up. New treatments aiming to reduce gastric atrophy and cancer risk are currently under development. Thus, treatment of autoimmune gastritis should focus on optimizing supplementation of vitamin and macronutrient deficiencies, symptomatic therapy that improves quality of life, and include cancer prevention measures. Clinical studies should address the possibility to arrest the inflammation process and to prevent progression of AIG. The author of the article suggests that itopride hydrochloride and rebamipide will be used for symptomatic and pathogenetic therapy. The problem facing gastroenterologists today is to develop domestic guidelines for the management and screening endoscopic intervals of patients with AIG.
