Treatment for these underlying infections can potentially lead to improvement in these patients. The Helicobacter Eradication Relief of Dyspeptic Symptoms trial (HEROES) reported eradication effects on symptoms and quality of life of H. pylori-positive patients with FD who met the Rome III International

Consensus criteria [14]. A large single-center randomized double-blind, placebo-controlled trial showed that the antibiotic-treated group of primary care patients with FD significantly benefited from eradication compared with the control group (p = .02). These data should be taken into account by investigators who are presently performing cost–utility studies on the economics of H. pylori eradication in primary care patients with FD. Similar results were reported Src inhibitor in a recent Chinese randomized, single-blind, placebo-controlled study [15] of 195 FD patients with H. pylori infection. The patients were divided into two groups: antibiotic case group and placebo control group. Symptoms of FD, such as postprandial fullness, early satiety, nausea, belching, epigastric pain, and epigastric burning, were assessed 3 months after H. pylori eradication. H. pylori eradication was reported effective in the subgroup of FD patients with epigastric pain syndrome. Yet, symptoms such as postprandial fullness, early satiety, nausea, and belching did not differ from those in the placebo group. A

recent Iranian endoscopy study investigated 217 FD patients with H. pylori infection and

histopathologic changes. Severity Talazoparib in vivo of symptoms was assessed by the Leeds Dyspepsia Questionnaire (LDQ) and its relationship to histopathologic changes. H. pylori infection status was also assessed [16]. Severity of dyspepsia symptoms was not higher in H. pylori-infected patients than noninfected patients, but in the presence of H. pylori infection and microscopic gastritis, microscopic duodenitis significantly worsened the LDQ symptom severity score (p < .001). The odds of experiencing severe symptoms in patients with severe microscopic duodenitis were 2.22 times greater than in individuals with very mild, mild, or moderate duodenitis. Gastroesophageal for reflux disease (GERD) is the most common GI diagnosis recorded in outpatient clinics. The association of H. pylori with GERD is still controversial. A cross-sectional study in Taiwan investigated 594 patients with no reflux symptoms; 14.5% of asymptomatic patients had endoscopic findings of erosive esophagitis [17]. The CLO test for H. pylori was performed during endoscopies. H. pylori infection, male gender, and hiatus hernia were significantly associated with asymptomatic erosive esophagitis (AEE). The study demonstrated that AEE is not a rare condition in the asymptomatic population and that H. pylori is associated with the disease. In contrast, in a Korean case–control study of 5616 H. pylori seropositive subjects, H.
