As a consequence, in autoimmune atrophic gastritis, gastric acid secretion is irreversibly impaired, and the resulting hypochlorhydria leads to the main clinical manifestations and is linked, directly or indirectly, to the long-term neoplastic complications of this disease. In the last few years, autoimmune atrophic gastritis has gained growing interest leading to the acquisition of new knowledge on different aspects of this disorder. Although reliable serological biomarkers are available and gastrointestinal endoscopy techniques have substantially evolved, the diagnosis of autoimmune atrophic gastritis is still affected by a considerable delay and relies on histopathological assessment of gastric biopsies. One of the reasons for the diagnostic delay is that the clinical presentations of autoimmune atrophic gastritis giving rise to clinical suspicion are very different, ranging from hematological to neurological\u2013psychiatric up to gastrointestinal and less commonly to gynecological\u2013obstetric symptoms or signs. Therefore, patients with autoimmune atrophic gastritis often seek advice from physicians of other medical specialties than gastroenterologists, thus underlining the need for increased awareness of this disease in a broad medical and scientific community.<\/jats:p>","DOI":"10.3390\/ijms25136818","type":"journal-article","created":{"date-parts":[[2024,6,21]],"date-time":"2024-06-21T05:33:28Z","timestamp":1718948008000},"page":"6818","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Autoimmune Gastritis and Hypochlorhydria: Known Concepts from a New Perspective"],"prefix":"10.3390","volume":"25","author":[{"given":"Marica","family":"Vavallo","sequence":"first","affiliation":[{"name":"Gastroenterology Unit, Sant\u2019Andrea University Hospital, Department of Medical-Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophia","family":"Cingolani","sequence":"additional","affiliation":[{"name":"Gastroenterology Unit, Sant\u2019Andrea University Hospital, Department of Medical-Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8123-6416","authenticated-orcid":false,"given":"Giulio","family":"Cozza","sequence":"additional","affiliation":[{"name":"Gastroenterology Unit, Sant\u2019Andrea University Hospital, Department of Medical-Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesco P.","family":"Schiavone","sequence":"additional","affiliation":[{"name":"Gastroenterology Unit, Sant\u2019Andrea University Hospital, Department of Medical-Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8178-2273","authenticated-orcid":false,"given":"Ludovica","family":"Dottori","sequence":"additional","affiliation":[{"name":"Gastroenterology Unit, Sant\u2019Andrea University Hospital, Department of Medical-Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Palumbo","sequence":"additional","affiliation":[{"name":"Gastroenterology Unit, Sant\u2019Andrea University Hospital, Department of Medical-Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9503-8639","authenticated-orcid":false,"given":"Edith","family":"Lahner","sequence":"additional","affiliation":[{"name":"Gastroenterology Unit, Sant\u2019Andrea University Hospital, Department of Medical-Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Castellana, C., Eusebi, L.H., Dajti, E., Iascone, V., Vestito, A., Fusaroli, P., Fuccio, L., D\u2019Errico, A., and Zagari, R.M.
