About this study

Official title: Pilot Study: Assessment of Gastric Motor and Sensory Function to a Mixed Liquid and Solid Test Meal by Gamma Scintigraphy, Magnetic Resonance Imaging and a Nutrient Drink Test in Health and Patients With Disorders of Gastric Function

Dyspeptic symptoms, such as pain after eating, bloating and nausea all have major impact on quality of life and health care costs. When no structural cause is identified, patients are diagnosed with functional dyspepsia. This trial aims to identify objective abnormalities of stomach function that explain patient's symptoms and establish diagnosis. Another group are diabetic patients who can often develop similar symptoms, labelled as diabetic gastroparesis. In some cases this is associated with delayed gastric emptying but not all.

24 patients with functional dyspepsia will be studied and 24 healthy controls (to establish normal ranges) and 24 diabetic patients with symptoms of functional dyspepsia.

The utility of 3 different non-invasive investigations will be assessed. At screening the nutrient drink test (NDT) asks the patient to drink 40ml of milkshake (0.75kcal/ml) every minute and score symptoms every 5 minutes. The patient continues until they reach the maximum tolerated volume.

Participants will then be randomized to undergo non-invasive imaging on two separate test days by magnetic resonance imaging (MRI) and gastric scintigraphy MRI will be completed with the patient ingesting 400ml of milkshake (identical to NDT) and 12 agar beads (no additional calories) of known breaking strength. The emptying of the stomach will be visualised with the MRI alongside symptom recording.

Gamma scintigraphy will ingest the same meal as for the MRI scan but radioactive labelling will allow the rate of liquid and solid meal emptying to be visualised alongside symptom recording.

Additionally, blood sugars will be recorded before nutrient drink test and at 15 and 30 minutes following ingestion of 400ml of milkshake and 12 agar beads.

Data will be analyzed to assess the association of objective abnormalities of gastric function and patient symptoms. Additionally the results of non-invasive imaging by MRI and GS will be compared to assess the optimal measurement of gastric function and emptying in this clinical scenario.

    Measured: study day

  6. Oro-caecal Transit time

    Time taken for 50% gastric contents to enter caecum

    Measured: study day

  7. Sensation threshold volume for fullness, bloating, nausea, heartburn and epigastric pain

    Gastric volume recorded at time of maximum symptom scores

    Measured: study day

  8. Sensation at 200ml and 400ml ingestion of test meal (fullness, bloating, nausea, heartburn, epigastric pain)

    Visual analogue score for each sensation (score up to 100 points)

    Measured: study day

  9. GI Hormone Assessment

    5 ml of blood will be taken at time 0, 30, 60 and 120 min. GI peptide hormones will then be analysed from the samples.

    Measured: Study day

Questions about this trial

What is this clinical trial studying?

A study testing Magnetic Resonance Imaging MRI, Gamma Scintigraphy and Assessment of Gastric motor and sensory function in people with Functional Dyspepsia and Diabetic Gastroparesis, run by Nottingham University Hospitals NHS Trust at 1 site in United Kingdom.

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 9 inclusion and 14 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 Apr 2014. 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 United Kingdom. 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.

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?

Maximum volume ingested at nutrient drink test (ml) (time frame: Study Day). The study lists 5 primary outcomes in all. 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 9 Apr 2014.
