The role of the parasympathetic component in this regard is less clear. Improvement of postprandial vasovagal complaints after <jats:italic>Helicobacter\u00a0pylori<\/jats:italic> eradication in three cases led us to assess autonomic response to feeding in <jats:italic>H.\u00a0pylori<\/jats:italic>\u2010positive patients in search for an exacerbated parasympathetic response.<\/jats:p><jats:p><jats:bold>Material and Methods:\u2002<\/jats:bold> Patients with mild or moderate chronic histologic gastritis were studied. Subjects with the same diagnosis but testing negative for <jats:italic>H.\u00a0pylori<\/jats:italic> were used as controls. Noninvasive cardiovascular tests were applied before and after feeding.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> On sympathetic tests, standing postprandial blood pressure was lower than preprandially in 5\/12\u00a0<jats:italic>H.\u00a0pylori<\/jats:italic>\u2010positive patients and in 0\/9 controls, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.045.

Regarding parasympathetic tests, the 4\u2010s unloaded exercise revealed greater initial heart rate response to unloaded cycling after feeding than preprandially again only in <jats:italic>H.\u00a0pylori<\/jats:italic>\u2010positive patients (1.40 \u00b1 0.20 versus 1.33 \u00b1 0.17, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.0195). On tests influenced by both branches of the autonomic system, a difference was seen in the chronotropic response to handgrip. Postprandial heart rate on effort of <jats:italic>H.\u00a0pylori<\/jats:italic>\u2010positive patients was not higher than preprandially in contrast to controls [intervals between 2 consecutive R waves on electrocardiogram (R\u2010R intervals) of 666 \u00b1 39 versus 685 \u00b1 62\u00a0ms, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.0195], suggesting blunted sympathetic activation in the former.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> Supporting the observations that motivate the study, our findings indicate blunted sympathetic reactivity and exacerbated vagal response to feeding in <jats:italic>H.\u00a0pylori<\/jats:italic>\u2010positive patients.<\/jats:p>","DOI":"10.1111\/j.1523-5378.2006.00397.x","type":"journal-article","created":{"date-parts":[[2006,5,8]],"date-time":"2006-05-08T17:03:40Z","timestamp":1147107820000},"page":"173-180","source":"Crossref","is-referenced-by-count":4,"title":["Cardiovascular Autonomic Response to Food Ingestion in Patients with Gastritis: A Comparison Between <i>Helicobacter pylori<\/i>\u2010Positive and \u2010Negative Patients"],"prefix":"10.1111","volume":"11","author":[{"given":"Jocemir Ronaldo","family":"Lugon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mauro Diniz","family":"Moreira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Mentor Ramos","family":"De Almeida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agostinho Soares","family":"Silva","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eliane Cathala Bordalo","family":"Esberard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kelb Bousquet","family":"Santos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angela Gouv\u00eaa","family":"Carvalho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luciana Claudia","family":"Mendes","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Claudio Lucas","family":"Da Nobrega","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,5,8]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"737","volume-title":"Clinical Autonomic Disorders","author":"Hoeldtke RD.","year":"1997"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-122-4-199502150-00009"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1042\/cs0770623"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0026-0495(80)90078-5"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI114313"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1042\/cs0860159"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.321.7262.659"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra020542"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(02)09711-8"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(03)14547-3"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10286-002-0030-1"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1746.2000.02052.x"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2036.16.s2.27.x"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2036.2000.014s1082.x"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199610000-00001"},{"key":"e_1_2_6_17_2","first-page":"75","article-title":"Testes auton\u00f4micos cardiovasculares.
