Until now, the occurrence of these events has been loosely defined as food intolerance. Instead, these conditions should be more properly defined as adverse food reactions (AFRs), which can consist of the presentation of a wide variety of symptoms which are commonly identified as irritable bowel syndrome (IBS). In addition, systemic manifestations such as neurological, dermatological, joint, and respiratory disorders may also occur in affected patients. Although the etiology and pathogenesis of some of them are already known, others, such as non-celiac gluten sensitivity and adverse reactions to nickel-containing foods, are not yet fully defined. The study aimed to evaluate the relationship between the ingestion of some foods and the appearance of some symptoms and clinical improvements and detectable immunohistochemical alterations after a specific exclusion diet. One hundred and six consecutive patients suffering from meteorism, dyspepsia, and nausea following the ingestion of foods containing gluten or nickel were subjected to the GSRS questionnaire which was modified according to the \u201cSalerno experts\u2019 criteria\u201d. All patients underwent detection of IgA antibodies to tissue transglutaminase, oral mucosal patch tests with gluten and nickel (OMPT), and EGDS, including biopsies. Our data show that GSRS and OMPT, the use of APERIO CS2 software, and the endothelial marker CD34 could be suggested as useful tools in the diagnostic procedure of these new pathologies. Larger, multi-center clinical trials could be helpful in defining these emerging clinical problems.<\/jats:p>","DOI":"10.3390\/nu15102353","type":"journal-article","created":{"date-parts":[[2023,5,18]],"date-time":"2023-05-18T06:32:58Z","timestamp":1684391578000},"page":"2353","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["New Insights and Evidence on \u201cFood Intolerances\u201d: Non-Celiac Gluten Sensitivity and Nickel Allergic Contact Mucositis"],"prefix":"10.3390","volume":"15","author":[{"given":"Nicoletta","family":"Greco","sequence":"first","affiliation":[{"name":"Department of Translational and Precision Medicine, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annalinda","family":"Pisano","sequence":"additional","affiliation":[{"name":"Department of Radiology, Oncology and Pathology, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Mezzatesta","sequence":"additional","affiliation":[{"name":"Department of Radiology, Oncology and Pathology, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta","family":"Pettinelli","sequence":"additional","affiliation":[{"name":"Department of Translational and Precision Medicine, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4989-2797","authenticated-orcid":false,"given":"Arianna","family":"Meacci","sequence":"additional","affiliation":[{"name":"Department of Translational and Precision Medicine, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5493-8772","authenticated-orcid":false,"given":"Maria Gemma","family":"Pignataro","sequence":"additional","affiliation":[{"name":"Department of Radiology, Oncology and Pathology, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3716-4303","authenticated-orcid":false,"given":"Carla","family":"Giordano","sequence":"additional","affiliation":[{"name":"Department of Radiology, Oncology and Pathology, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Picarelli","sequence":"additional","affiliation":[{"name":"Department of Translational and Precision Medicine, Sapienza University of Rome, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Gargano, D., Appanna, R., Santonicola, A., De Bartolomeis, F., Stellato, C., Cianferoni, A., Casolaro, V., and Iovino, P.
