Patients with BM and low-grade dysplasia were excluded from this study because of the uncertainty in differentiating low-grade dysplasia from regenerative epithelium. A total of 712 patients with non-ulcer dyspepsia (NUD; average age 40.0 \u00b1 16.1 years; m:f 0.3:1) served as a control group. &lt;i&gt;Results:&lt;\/i&gt; The percentage of Hp infection did not differ between patients with GORD with (53.3%)\/without BM (51.4%) and neoplasia (47.8%), but is statistically significantly lower than in patients with NUD (65.7%). &lt;i&gt;Conclusion:&lt;\/i&gt; Our analysis shows that patients with GORD and Hp infection have no increased risk for the development of BM or neoplasia in BM. Since Hp infection is significantly less frequent in GORD than in NUD patients, a protective effect of the Hp infection is a possibility worth discussing.<\/jats:p>","DOI":"10.1159\/000007820","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T15:42:49Z","timestamp":1050421369000},"page":"225-231","source":"Crossref","is-referenced-by-count":37,"title":["&lt;i&gt;Helicobacter pylori&lt;\/i&gt; Infection: Protection against Barrett\u2019s Mucosa and Neoplasia?"],"prefix":"10.1159","volume":"62","author":[{"given":"M.","family":"Vieth","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Masoud","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Meining","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Stolte","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2000,10,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/0140-6736(93)90938-D"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1006\/bbrc.1997.7485"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0142(19980901)83:5<876::AID-CNCR11>3.0.CO;2-S"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199610000-00001"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199903183401101"}],"container-title":["Digestion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/7820","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/7820","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:41:56Z","timestamp":1745469716000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000007820"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000]]},"references-count":5,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2000,7,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000007820","archive":["Portico"],"relation":{},"ISSN":["0012-2823","1421-9867"],"issn-type":[{"value":"0012-2823","type":"print"},{"value":"1421-9867","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000]]}}}
