Trial summary

Although all PPIs are effective, there are some differences in their clinical performance, particularly in terms of the degree and speed of gastric acid suppression. Few data are also available about their effect of the pathophysiological mechanisms of gastritis and peptic ulcer disease. Read more about this study

About this study

Official title: A Clinical Study of the Efficacy of Esomeprazole or Rabeprazole on the Pattern of Release of Pro- and Anti-inflammatory Cytokines From Gastric Mucosa of Patients With Peptic Ulcer Disease

Although all PPIs are effective, there are some differences in their clinical performance, particularly in terms of the degree and speed of gastric acid suppression. Few data are also available about their effect of the pathophysiological mechanisms of gastritis and peptic ulcer disease. Aim of the present study is to investigate the effect of therapy with esomeprazole or rabeprazole on the mechanism of pathogenesis of gastritis and particularly on the pattern of release of pro- and anti- inflammatory cytokines associated to peptic ulcerative process by the gastric mucosa.

Although all PPIs are effective, there are some differences in their clinical performance, particularly in terms of the degree and speed of gastric acid suppression. Few data are also available about their effect of the pathophysiological mechanisms of gastritis and peptic ulcer disease.

Triggering receptor expressed on myeloid cells (TREM)-1 is a recently discovered receptor expressed on the surface of neutrophils and monocytes. Engagement of TREM-1 has been reported to trigger the synthesis of proinflammatory cytokines. A soluble form of TREM-1, named sTREM-1, was observed and identified at significant levels in serum samples from patients with disease of the gastrointestinal tract inflammatory bowel disease. rendering interest about the implication of sTREM-1 in their pathogenesis.

sTREM-1 was also found elevated in the gastric juice of patients with peptic ulcer disease being correlated to the degree of the infiltration of the gastric mucosa by neutrophils.

Published data of our group elicit that sTREM-1 secretion is a crucial parameter for evolution from chronic gastritis to peptic ulcer disease. Samples of biopsies of gastric mucosa were cultured in the absence/presence of endotoxins showing that the inflamed mucosa was a potent secretor of sTREM-1 whatever ceased to exist post-antisecretory treatment.

Aim of the present study is to investigate the effect of therapy with esomeprazole or rabeprazole on the mechanism of pathogenesis of gastritis and particularly on the pattern of release of pro- and anti- inflammatory cytokines associated to peptic ulcerative process by the gastric mucosa.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Endoscopy of upper GI tractProcedure or surgery

    Also called Gastroscopy

    Upper GI endoscopy, one time on diagnosis and a second time 15 days after the end of the treatment. Gastric juice will be aspirated immediately after the entrance of the endoscope into the gastric lumen. Four biopsy specimens will be obtained from adjacent areas of the gastric antrum. Each biopsy will be used for in vitro culture. Blood will be sampled from one antecubital vein under aseptic conditions.

    Each patient will be given antisecretory treatment and - if necessary- eradication treatment of H. pylori according to international guidelines.

Study groups in NCT00534443
Study groupRoleWhat they receive
1ExperimentalA total of 130 patients with peptic ulcer disease and /or chronic gastritis will be enrolled in the study after written informed consent. Patients will be prescribed oral treatment with rabeprazole or esomeprazole according to standard guidelines. Rabeprazole is administered 20mg twice daily and esomeprazole 10 mg once daily. Selection of rabeprazole or esomeprazole is at the discretion of the attending physicians. The drug is administered for four weeks in patients with duodenal ulcers, for eight weeks in patients with gastric ulcers and for four weeks in patients with chronic gastritis.
Receives: Procedure: Endoscopy of upper GI tract

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Endoscopy of upper GI tract in people with Peptic Ulcer, run by University of Athens at 1 site in Greece.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Greece. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of treatment on changes of cytokines levels in serum of patients (time frame: Baseline and 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00534443, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Aug 2011.
