A literature search from 1996 to April 2009 identified 19 additional cases of intestinal spirochetosis in patients with HIV infection. Analysis of cases showed that intestinal spirochetosis causes chronic diarrhoea in men who have sex with men (92% of patients with reported HIV infection risk factors) who are not severely immunosuppressed (70% with CD4 lymphocyte cells &gt;200\/\u03bcL). Colonoscopy examination often revealed normal appearance mucosa. Haematoxylin and eosin stain of biopsy samples showed the presence of spirochetes, but Warthin\u2013Starry silver staining makes organisms easier to detect. Patients promptly responded to metronidazole or penicillin therapy. In summary, invasive intestinal spirochetosis should be considered in the differential diagnosis of patients with HIV infection and chronic diarrhoea. <\/jats:p>","DOI":"10.1258\/ijsa.2009.009177","type":"journal-article","created":{"date-parts":[[2009,10,21]],"date-time":"2009-10-21T00:45:29Z","timestamp":1256085929000},"page":"803-805","source":"Crossref","is-referenced-by-count":16,"title":["Intestinal spirochetosis as a cause of chronic diarrhoea in patients with HIV infection: case report and review of the literature"],"prefix":"10.1177","volume":"20","author":[{"given":"J","family":"Ena","sequence":"first","affiliation":[{"name":"HIV Clinic, Department of Internal Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Sim\u00f3n-Ayl\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Pathology, Hospital Marina Baixa, Villajoyosa, Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F","family":"Pasquau","sequence":"additional","affiliation":[{"name":"HIV Clinic, Department of Internal Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,11,1]]},"reference":[{"key":"bibr-IJSA-09-177C1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.2000.03365.x"},{"key":"bibr-IJSA-09-177C2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinmicnews.2005.05.002"},{"key":"bibr-IJSA-09-177C3","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.37.6.2093-2098.1999"},{"key":"bibr-IJSA-09-177C4","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.39.1.347-350.2001"},{"key":"bibr-IJSA-09-177C5","doi-asserted-by":"publisher","DOI":"10.1309\/G7U6BD85W4G3WJ0J"},{"key":"bibr-IJSA-09-177C6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.2003.08251.x"},{"key":"bibr-IJSA-09-177C7","doi-asserted-by":"publisher","DOI":"10.1086\/424461"},{"key":"bibr-IJSA-09-177C8","first-page":"2441","volume":"18","author":"Martinez MW","year":"2004","journal-title":"AIDS"},{"key":"bibr-IJSA-09-177C9","doi-asserted-by":"publisher","DOI":"10.1590\/S0037-86822005000100011"},{"key":"bibr-IJSA-09-177C10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1746.2006.04150.x"},{"key":"bibr-IJSA-09-177C11","doi-asserted-by":"publisher","DOI":"10.1016\/j.diagmicrobio.2007.05.002"},{"key":"bibr-IJSA-09-177C12","first-page":"551","volume":"17","author":"Braza J","year":"2007","journal-title":"AIDS Read"},{"key":"bibr-IJSA-09-177C13","first-page":"128","volume":"78","author":"Peruzzi S","year":"2007","journal-title":"Acta Biomed"},{"key":"bibr-IJSA-09-177C14","doi-asserted-by":"publisher","DOI":"10.1086\/595699"},{"key":"bibr-IJSA-09-177C15","doi-asserted-by":"publisher","DOI":"10.1016\/j.eimc.2008.04.001"},{"key":"bibr-IJSA-09-177C16","doi-asserted-by":"publisher","DOI":"10.1007\/s15010-003-3145-y"},{"key":"bibr-IJSA-09-177C17","doi-asserted-by":"publisher","DOI":"10.1093\/clinids\/21.5.1159"},{"key":"bibr-IJSA-09-177C18","doi-asserted-by":"crossref","unstructured":"Bait-MerabetL, ThilleA, LegrandP, Brun-BuissonC, CattoirV.
