OBJECTIVE: To compare the diagnostic value of three tests based in endoscopic gastric biopsies histopathological evaluation with hematoxylin-eosin (H-E) staining, urease rapid test and microbiological culture for detecting Helicobacter pylori active infection, in order to make recommendations for daily clinical practice. METHODS: Gastric biopsies from 115 adult patients (85 female\/30 male) were obtained by upper gastrointestinal endoscopy and studied by histopathological evaluation with H-E (antrum-corpus), urease test in 2 hours (antrum) and microbiological culture (antrum). RESULTS: Helicobacter pylori active infection was diagnosed in 67% of patients. Helicobacter pylori active infection was detected by histopathological evaluation with H-E, urease test and microbiological culture in 87%, 79% and 70% of the positive cases, respectively. There were significant differences when histopathological evaluation with H-E and urease test rapid test when compared with microbiological test (P&lt;0.01). There was no significant difference between histopathological evaluation with H-E and urease test (P = 0.7). The kappa index of agreement for histopathological evaluation with H-E\/urease test was 0.56, histopathological evaluation with H-E\/microbiological culture 0.6, and urease test\/microbiological culture 0.64. CONCLUSIONS: In a hospital setting like the one studied, histopathological evaluation with H-E and urease test are the most recommended tests for diagnosis of Helicobacter pylori active infection based in endoscopic biopsies. If pathological information of gastric lesions will be required, histopathological evaluation with H-E is essential. Urease test is mandatory if a prompt diagnosis is necessary. Microbiological culture can be used in cases of persistent or complicated infection, which may require studies on Helicobacter virulence or antimicrobial susceptibility. Selected cases might demand a combination of several tests. The three tests exhibit a good concordance level for Helicobacter pylori active infection diagnosis.<\/jats:p>","DOI":"10.1590\/s0004-28032011000300007","type":"journal-article","created":{"date-parts":[[2011,9,15]],"date-time":"2011-09-15T20:03:43Z","timestamp":1316117023000},"page":"190-194","source":"Crossref","is-referenced-by-count":5,"title":["Comparison of three methods based on endoscopic gastric biopsies for diagnosis of Helicobacter pylori active infection in a clinical setting"],"prefix":"10.1590","volume":"48","author":[{"given":"Gabriel","family":"Arismendi-Morillo","sequence":"first","affiliation":[{"name":"Instituto de Investigaciones Biol\u00f3gicas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ileana","family":"Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones Biol\u00f3gicas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edgardo","family":"Mengual","sequence":"additional","affiliation":[{"name":"Instituto de Investigaciones Biol\u00f3gicas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alisbeth","family":"Fuenmayor","sequence":"additional","affiliation":[{"name":"Escuela de Bioan\u00e1lisis"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gisela","family":"Romero","sequence":"additional","affiliation":[{"name":"Universidad del Zulia,  Venezuela"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maribel","family":"Lizarz\u00e1bal","sequence":"additional","affiliation":[{"name":"Universidad del Zulia,  Venezuela"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"2232","DOI":"10.3748\/wjg.v9.i10.2232","article-title":"Interobserver variation in histopathological assessment of Helicobacter pylori gastritis","volume":"9","author":"Aydin O","year":"2003","journal-title":"World J Gastroenterol"},{"key":"ref2","first-page":"475","article-title":"Efficacy of four widely used techniques of the diagnosis of Helicobacter pylori infection in gastric ulcer disease","volume":"200","year":"2000","journal-title":"Rev Clin Esp","ISSN":"http:\/\/id.crossref.org\/issn\/0014-2565","issn-type":"print"},{"key":"ref3","first-page":"336","article-title":"How (who: ) and when to test or retest for H.
