Analysis of the Influence of Interleukin-1β Gene Polymorphism on Gastric Inflammatory Response and Precancerous Lesions Development in Patients with Functional Dyspepsia.

The present study aimed to evaluate the influence of the 31C/T polymorphism on gastric inflammatory response and precancerous lesions development - atrophic gastritis (AG) and intestinal metaplasia (IM) - in patients positive for infection with functional dyspepsia (FD). The diagnosis of FD followed the Rome III criteria, and the infection was evaluated by urease test and histological examination of gastric biopsies (corpus, antrum, and incisura). The severity of chronic inflammation and inflammatory activity, as well as the presence of precancerous lesions were evaluated accordingly to the updated Sydney System.

Potential roles of Helicobacter pylori treatment, body mass index and waist circumference in the causation of erosive esophagitis: a randomized clinical trial (HEROES-GERD).

Background: In recent decades, the prevalence of gastroesophageal reflux disease (GERD) and obesity has been increasing while Helicobacter pylori infection has been decreasing.

Objective: To evaluate if H. pylori treatment, excess body weight and other anthropometric measurements are associated with incident erosive esophagitis, as a secondary objective of a trial which tested the efficacy of treatment of H.

Prevalence of celiac disease in a large cohort of young patients with type 1 diabetes.

Background: Serological screening for celiac disease (CD) allows the identification of individuals genetically predisposed, as type 1 diabetes mellitus (T1DM). However, the diagnosis is confirmed by intestinal biopsy. The aim was to determine the prevalence of immunoglobulin-A anti-tissue transglutaminase antibodies (IgA-tTG) and CD in a large cohort of young T1DM patients.

Clinical outcomes of eradication of Helicobacter pylori in nonulcer dyspepsia in a population with a high prevalence of infection: results of a 12-month randomized, double blind, placebo-controlled study.

Ninety-one Helicobacter pylori-positive patients with nonulcer dyspepsia were randomized to receive either lansoprazole, amoxicillin, and clarithromycin or lansoprazole and placebo. A validated questionnaire assessed dyspeptic symptoms at baseline and at 3, 6, and 12 months. Endoscopies and biopsies were performed at baseline and at 3 and 12 months.

Development and validation of a cross-cultural questionnaire to evaluate nonulcer dyspepsia: the Porto Alegre Dyspeptic Symptoms Questionnaire (PADYQ).

Despite its high prevalence, nonulcer dyspepsia is still difficult to study, due to the lack of adequate tools to measure significant outcomes. The objective of this study was to develop and validate a symptom-focused, disease-specific questionnaire to evaluate patients with nonulcer dyspepsia. For that, the questionnaire was carefully written following widely accepted terminology, so as to facilitate translation and validation in other languages and cultures.
