Abstract
BACKGROUND
Autoimmune gastritis (AIG) is a progressive, chronic, immune-mediated inflammatory disease characterized by the destruction of gastric parietal cells leading to hypo/anacidity and loss of intrinsic factor. Gastrointestinal symptoms such as dyspepsia and early satiety are very common, being second in terms of frequency only to anemia, which is the most typical feature of AIG.
AIM
To address both well-established and more innovative information and knowledge about this challenging disorder.
METHODS
An extensive bibliographical search was performed in PubMed to identify guidelines and primary literature (retrospective and prospective studies, systematic reviews, case series) published in the last 10 years.
RESULTS
A total of 125 records were reviewed and 80 were defined as fulfilling the criteria.
CONCLUSION
AIG can cause a range of clinical manifestations, including dyspepsia. The pathophysiology of dyspepsia in AIG is complex and involves changes in acid secretion, gastric motility, hormone signaling, and gut microbiota, among other factors. Managing dyspeptic symptoms of AIG is challenging and there are no specific therapies targeting dyspepsia in AIG. While proton pump inhibitors are commonly used to treat dyspepsia and gastroesophageal reflux disease, they may not be appropriate for AIG. Prokinetic agents, antidepressant drugs, and non-pharmacological treatments may be of help, even if not adequately evidence-based supported. A multidisciplinary approach for the management of dyspepsia in AIG is recommended, and further research is needed to develop and validate more effective therapies for dyspepsia.
Core Tip: The management of dyspepsia in patients with autoimmune gastritis (AIG), a chronic, immune-mediated disease, remains a challenge, as it can overlap with functional dyspepsia and gastroesophageal reflux disease. Currently, there are no specific therapies. A tailored treatment approach based on a better understanding of putative pathogenic mechanisms underlying symptoms is needed. Prokinetic agents, antidepressant drugs, and non-pharmacological treatments may be helpful, although not adequately evidence-based supported. As a future perspective, targeting dyspepsia in AIG based on changes in the microbiota and advanced endoscopic techniques to treat severe dyspeptic symptoms might be an area of ongoing research.
