About this study

Official title: A Comparative Study of Epigastric Pain Syndrome and Postprandial Distress Syndrome in Personality, Helicobacter Pylori Infection, Gastric Emptying and Response to Lansoprazole Treatment

The purpose of this study is to compare postprandial distress syndrome and epigastric pain syndrome in demographics psychological features, infection of Helicobacter pylori, gastric emptying and therapeutic response to lansoprazole.

Read the detailed description

Functional dyspepsia is a common clinical disorder with significant impact on quality of life and with enormous social cost. Previous studies have revealed that functional dyspepsia is not a homogenous disease but a heterogenous symptom complex. Because of heterogeneity in etiology and pathogenesis, no specific treatment is appropriate for all patients with functional dyspepsia. Currently available treatments demonstrated efficacy only in subsets of patients.

Appropriate subgrouping of functional dyspepsia, which categorizes more homogenous patients into the same group, will correlate better with specific etiologic factors and pathogenetic mechanisms. Consequently patients may have appropriate specific treatment based on more directed pathologenesis and subgrouping. To this end, American Gastroenterology Association launched new edition of clinical guide for functional gastrointestinal disorder, the Rome III in May 2006. The new diagnostic criteria of Rome III de-emphasized functional dyspepsia as an entity and recommended sub-classification into two conditions: postprandial distress syndrome and epigastric pain syndrome. However whether this new diagnostic criteria and systems are effective and clinically relevant remains unknown.

Aims:

We aim to compare postprandial distress syndrome and epigastric pain syndrome in demographics psychological features, infection of Helicobacter pylori, gastric emptying and therapeutic response to lansoprazole.

What participants receive

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

  • gastric scintigraphyRadiation

    Also called gastric emptying time

    All tests start after overnight fast. Test meals consists of 120g scrambled egg, two slices of toasted bread, 30g of strawberry jam and 120ml of water. 12MBg (0.33mCi) of 99mTc sulfur colloid is mixed with egg thoroughly before the mixture cooked in a microwave oven for 2 minutes. All meals are prepared on the morning of examination and consumed within 20 minutes.

    Anterior and posterior images of the gastric region are taken within one minute after completion of test meals. Subsequent images are taken every 2 minutes in the first 60 minutes and at 120 minutes and 180 minutes. One-min images of gastric region at upright position are taken in the 140keV 99mTc peak with a 20% window.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary end point of the study is to compare the gastric emptying time in epigastric pain syndrome and that in postprandial distress syndrome

    Measured: After four-week treatment of lansoprazole

Secondary outcomes (1)
  1. Psychiatric distress, personality traits, infection of H. pylori and symptom improvement to lansoprazole

    Measured: after four-week treatment of lansoprazole

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing gastric scintigraphy in people with Functional Dyspepsia and Epigastric Pain Syndrome, run by National Taiwan University Hospital at 1 site in Taiwan.

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 2 inclusion and 8 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: withdrawn, as of the sponsor's last update on 10 Mar 2010. 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 Taiwan. 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 was withdrawn before enrolling participants, so there are no results.

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?

Primary end point of the study is to compare the gastric emptying time in epigastric pain syndrome and that in postprandial distress syndrome (time frame: After four-week treatment of lansoprazole). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 Mar 2010.
