An interventional study of 400ml of Liquid Nutrient Drink in Functional Dyspepsia, sponsored by Nottingham University Hospitals NHS Trust. Completed at 1 site in United Kingdom. Open to participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-01-02.

Dyspeptic symptoms such as abdominal pain, bloating and nausea after a meal are common; however the cause of these problems in many patients is often unclear despite medical investigation. This is because "dyspeptic symptoms" are only rarely related to acid reflux, stomach ulcers or cancer that can be diagnosed by endoscopy. Rather, the cause is abnormal stomach function, so-called "functional dyspepsia", a condition in which the digestive system does not function normally after a meal. Gastric scintigraphy is the standard investigation of stomach function in patients with this condition. It involves eating a small test meal that includes a tiny dose of radioactive material so that the movement of food can be visualised as it empties from the stomach. An important limitation of this approach is that symptoms are rarely caused and delayed emptying after a small meal is present only in a minority of patients and, thus, the ability of this investigation to explain the cause of symptoms or guide medical treatment is limited.
This research project is designed to compare three new investigations of stomach function using a relatively large meal. This information will help to explain the causes of symptoms after a meal. The investigations to be tested include: (1) Nutrient Drink Test, (2) Gastric Scintigraphy and (3) Magnetic Resonance Imaging. All three tests are safe, easy to perform and non-invasive (i.e. do not involve inserting catheters through the nose and into the stomach or taking blood). The results should provide more useful information to doctors looking after patients with dyspeptic symptoms.
This study will compare test results from healthy volunteers, with patients attending clinic for investigation of dyspeptic symptoms. The aim is to document abnormal function of the stomach and intestines and to identify the causes of dyspeptic symptoms after a meal.
The Nutrient Drinking Test will be performed as part of the screening visit to ensure that all patients that consent to participate in the full study are able to complete the imaging studies that require ingestion of 400ml liquid nutrient (Fortisip Vanilla (Nutricia Clinical) diluted 1:1 with water to 0.75kcal/ml, 4.5g fat/100ml).
Subjects will drink one from a series of beakers containing 40ml liquid nutrient every minute. During the drinking test, subjects will score satiety, fullness, bloating, heartburn, nausea and epigastric pain at 5-min intervals using a 100mm visual analogue scale (sample attached). Participants will be instructed to cease intake when they reported maximal satiety or very severe dyspeptic symptoms (defined as VAS score of >90 mm). The total volume ingested will be recorded. Symptoms will be assessed again 15 and 30 min after cessation of intake.
If the subject fulfils the inclusion and exclusion criteria including ingestion of ≥400ml at the drinking test and consents to continue then appointments will be made for gamma scintigraphy and MRI studies according to a prospective randomization plan.
MRI Study Day After eligibility has been confirmed subjects will ingest the paramagnetic contrast labelled liquid nutrient test meal according to a standardized protocol. Subjects will drink one from a series of ten beakers containing 40ml liquid nutrient every minute. During the test meal, subjects will score satiety, fullness, bloating, heartburn, nausea and epigastric pain at baseline, 5 and 10 minute using a visual analogue scale (VAS 0-100 mm). These measurements will be repeated at 30min and at the conclusion of the imaging study (see below).
Studies will be performed using a 1.5T whole MRI system (Intera, Philips, Best, The Netherlands). Six rectangular surface coils (height = 20 cm, width = 10 cm), fixed around the abdomen and connected to independent receive channels were used for signal detection.
Gamma Scintigraphy Study Day After eligibility has been confirmed subjects will ingest the radiolabelled liquid nutrient test meal according to a standardized protocol. Subjects will drink one from a series of ten beakers containing 40ml liquid nutrient every minute. During the test meal, subjects will score satiety, fullness, bloating, heartburn, nausea and epigastric pain at baseline, 5 and 10 min using a visual analogue scale (VAS 0-100 mm).

Exclusion Criteria:
60 healthy volunteers with no functional dyspepsia as defined by the Rome Questionnaire and no more than mild symptoms on maximum 1 days a week on the GSRS, that meet inclusion and exclusion criteria will be recruited. Eligible subjects will be block randomized by sex and age such that 10 men and women in each age group (\<40, 41-60, \>60) are recruited.
Other: 400ml of Liquid Nutrient Drink
20 patients with functional dyspepsia with postprandial distress syndrome as defined by the Rome IV Questionnaire and at least moderate symptom severity on at least 3 days a week that meet the inclusion and exclusion criteria will be recruited to provide pilot data in the local patient population
Other: 400ml of Liquid Nutrient Drink
12MBq Technetium-99m-DTPA will be added as a non-absorbable marker incorporated into liquid nutrient drink Fortisip Vanilla (Nutricia Clinical)
