However, insufficient data have been obtained regarding underweight GERD patients. Post hoc analysis of a multicenter prospective cohort study was conducted to evaluate subjective symptoms and health\u2010related quality of life (HRQOL) in underweight GERD patients (body mass index [BMI]\u2003&lt;\u200318.5) and to evaluate therapeutic response to proton pump inhibitors.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> A total of 2646 patients who underwent endoscopy were classified by BMI and analyzed. Rabeprazole was administered for 8\u2003weeks. Subjective symptoms and HRQOL were assessed using questionnaires (F\u2010Scale and SF\u20108\u2122).<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> Baseline endoscopy revealed 29.2% of patients had non\u2010erosive reflux disease (NERD). Underweight status was identified in 5.8% of GERD patients, and mean baseline symptoms score and SF\u20108 physical component summary (PCS) score were 18.6 and 42.4, respectively, reflecting greater impairment compared with the values of 15.4 and 45.6 in normal\u2010weight patients (BMI\u2003\u2265\u200322 but &lt;\u200325). Treatment with rabeprazole resulted in a decrease from 18.6 at baseline to 6.7 at week 8 in underweight reflux esophagitis subjects, and from 15.0 to 6.3 in underweight NERD patients. PCS score improved in underweight patients. These changes were about the same as in normal\u2010weight or obese patients.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> Japanese GERD patients are often obese, as reported previously, but some GERD patients are underweight. Baseline symptoms and QOL in underweight GERD patients tended to be more severe than in normal\u2010weight patients, but therapeutic response with proton pump inhibitors was about the same as in normal\u2010weight or obese patients.<\/jats:p>","DOI":"10.1111\/j.1440-1746.2011.07042.x","type":"journal-article","created":{"date-parts":[[2011,12,6]],"date-time":"2011-12-06T11:46:50Z","timestamp":1323172010000},"page":"913-918","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Symptoms and quality of life in underweight gastroesophageal reflux disease patients and therapeutic responses to proton pump inhibitors"],"prefix":"10.1111","volume":"27","author":[{"given":"Michio","family":"Hongo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroto","family":"Miwa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Motoyasu","family":"Kusano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"J\u2010FAST group","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,4,20]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1053\/gast.1997.v112.pm9178669"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/gut.2004.057497"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-143-3-200508020-00006"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1080\/003655299750026326"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.2008.01979.x"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2006.09.016"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00535-007-2128-7"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00535-010-0342-1"},{"key":"e_1_2_7_10_2","unstructured":"WareJE KosinskiM DeweyJE GandekB.How to score and interpret single\u2010item health status measures: a manual for users of the SF\u20108 health survey.
