OBJECTIVES: Helicobacter pylori is a carcinogen; gastric carcinoma involves a multistep process from chronic gastritis to atrophy, intestinal metaplasia, and dysplasia. The aims of this study were to determine the types of mucosa at different gastric sites in H. pylori-infected and uninfected patients, and whether the presence of antral-type mucosa in the incisura, body, and fundus is associated with gastric atrophy and intestinal metaplasia.
METHODS: Two hundred and sixty-eight patients ...

Apoptosis in gastric epithelium induced by helicobacter pylori infection: implications in gastric carcinogenesis
[ PUBLICATION ]
OBJECTIVES: Helicobacter pylori is an identified carcinogen for gastric cancer, however, the underlying mechanisms remain to be defined. In this review, we sought to elucidate the role of apoptosis in gastric carcinogenesis, to determine the influence of H. pylori infection on apoptosis, and finally to provide insights into the mechanisms by which H. pylori may lead to gastric carcinogenesis.
METHODS: A broad-based MEDLINE and Current Contents literature search was performed to identify ...

Background: Patient-rated symptom assessments are needed for evaluating the effectiveness of medical treatments and for monitoring outcomes in gastroparesis. Objective: This paper summarizes the development and psychometric evaluation of a new instrument, the Gastroparesis Cardinal Symptom Index (GCSI), for assessing severity of symptoms associated with gastroparesis. Methods: The GCSI was based on reviews of the medical literature, patient focus groups, and interviews with clinicians. A ...

OBJECTIVES: Helicobacter pylori (H. pylon) infection seems to induce antralization (ie., gastric mucosal transformation from transitional or body type to antral type), which is strongly associated with gastric atrophy and intestinal metaplasia. The aim of this study was to determine the topographic associations of Ki-67 (a protein expressed in proliferative cells), Bax (a pro-apoptotic protein), and Bcl-2 (an antiapoptotic protein) expression with antralization.
METHODS: In each of 104 ...

Small Intestinal Bacterial Overgrowth in Irritable Bowel Syndrome: A Systematic Review and Meta-Analysis of Case-Control Studies.
[ PUBLICATION ]
INTRODUCTION: We conducted a systematic review and meta-analysis to compare the prevalence of small intestinal bacterial overgrowth (SIBO) in patients with irritable bowel syndrome (IBS) and controls.
METHODS: Electronic databases were searched up to December 2018 for studies reporting SIBO prevalence in patients with IBS. Prevalence rates, odds ratios (ORs), and 95% confidence intervals (CIs) of SIBO in patients with IBS and controls were calculated.
RESULTS: We included 25 studies with ...

BACKGROUND: On-demand therapy may offer an effective approach to the long-term management of gastro-oesophageal reflux disease (GORD) without oesophagitis.
AIM: To examine the efficacy of the novel proton pump inhibitor esomeprazole as on-demand therapy in endoscopy-negative GORD.
PATIENTS AND METHODS: Endoscopy-negative GORD patients who achieved complete resolution of heartburn after short-term esomeprazole or omeprazole treatment (n = 721) were randomized to esomeprazole 20 mg (n = ...

BACKGROUND: Disturbed bowel habit, diarrhoea or constipation is a key manifestation of irritable bowel syndrome (IBS). In some patients, diarrhoea and constipation alternate, giving rise to the so-called alternating subtype.
AIMS: To assess IBS subtype breakdown (constipation (C-IBS), diarrhoea (D-IBS) or alternating (A-IBS)) according to the Rome II criteria and patients' self-assessment, the predominance in the alternating subtype (i.e. constipation, diarrhoea or neither), and the ...

Prevention of Ulcers by Esomeprazole in At-Risk Patients Using Non-Selective NSAIDs and COX-2 Inhibitors
[ PUBLICATION ]
OBJECTIVES: Proton pump inhibitors reduce ulcer recurrence in non-steroidal anti-inflammatory drug (NSAID) users, but their impact in at-risk ulcer-free patients using the current spectrum of prescribed agents has not been clearly defined. We assessed esomeprazole for ulcer prevention in at-risk patients (> or = 60 yr and/or ulcer history) taking NSAIDs, including COX-2 inhibitors. Such studies are particularly relevant, given that concerns regarding adverse cardiovascular outcomes among ...

Efficacy of antidepressants and psychological therapies in irritable bowel syndrome: systematic review and meta-analysis
[ PUBLICATION ]
OBJECTIVE: Irritable bowel syndrome (IBS) is a chronic functional gastrointestinal disorder. Evidence for treatment of the condition with antidepressants and psychological therapies is conflicting.
DESIGN: Systematic review and meta-analysis of randomised controlled trials (RCTs). MEDLINE, EMBASE and the Cochrane Controlled Trials Register were searched (up to May 2008).
SETTING: RCTs based in primary, secondary and tertiary care.
PATIENTS: Adults with IBS.
INTERVENTIONS: Antidepressants ...

INTRODUCTION: Motilin-receptor agonists are prokinetics; whether they relieve the symptoms of functional dyspepsia is unknown. We aimed to test the efficacy of the motilin agonist ABT-229 in functional dyspepsia patients with and without delayed gastric emptying.
METHODS: Patients were randomized with postprandial symptoms and documented functional dyspepsia by endoscopy (n=589 in intention-to-treat analysis). Patients were assigned to either the delayed or normal gastric emptying ...

Diagnostic yield of alarm features in irritable bowel syndrome and functional dyspepsia
[ PUBLICATION ]
OBJECTIVE: The diagnostic value of the addition of alarm symptoms in distinguishing functional from organic gastrointestinal disease remains uncertain. We aimed to establish the value of alarm features in differentiating between organic disease and irritable bowel syndrome (IBS) and functional dyspepsia (FD).
METHODS: A total of 568 consecutive patients (63% female; mean age 44.7 years) completed a detailed symptom questionnaire and then received a complete diagnostic workup, as ...

Effect of fibre, antispasmodics, and peppermint oil in the treatment of irritable bowel syndrome: systematic review and meta-analysis
[ PUBLICATION ]
OBJECTIVE: To determine the effect of fibre, antispasmodics, and peppermint oil in the treatment of irritable bowel syndrome.
DESIGN: Systematic review and meta-analysis of randomised controlled trials.
DATA SOURCES: Medline, Embase, and the Cochrane controlled trials register up to April 2008. Review methods Randomised controlled trials comparing fibre, antispasmodics, and peppermint oil with placebo or no treatment in adults with irritable bowel syndrome were eligible for inclusion. ...

BACKGROUND: Irritable bowel syndrome (IBS) prevalence estimates are essential for measuring the importance of the problem and the burden of the illness. However, IBS diagnosis is based on clinical criteria which have changed over time. The aim of this study was to assess how the use of different diagnostic criteria influences estimated IBS prevalence and, in particular, to compare how this prevalence varies using the new Rome II criteria and previous diagnostic criteria.
METHODS: An ...

Initial endoscopy or empirical therapy with or without testing for Helicobacter pylori for dyspepsia: A decision analysis
[ PUBLICATION ]
BACKGROUND & AIMS: Empirical therapy has been proposed for initial management of dyspepsia. The aim of this study was to evaluate initial endoscopy, empirical therapy, and testing for Helicobacter pylori in the management of patients with a new onset of dyspepsia.
METHODS: Decision analysis was used to compare the direct medical charges in the first year after the onset of dyspepsia for patients managed by initial endoscopy or empirical therapy, with or without initial testing for H. ...
