This metadata record and it's attached files make statements about the kinds of data collected as part of this research, and set out policies for governance of that data, now and in the future.

Description: This study was undertaken to understand more about functional dyspepsia, a common condition of recurring symptoms of indigestion that have no obvious cause but can have a profound adverse effect on quality of life. Honey has been used since ancient times to treat or prevent indigestion symptoms. Studies show that mānuka honey has unique natural compounds that could reduce inflammation in the upper gastrointestinal tract. This inflammation is associated with the symptoms of functional dyspepsia and reducing inflammation might improve indigestion symptoms.

Comvita Ltd is a New Zealand owned mānuka honey manufacturer. They have recently identified a unique natural compound in mānuka honey, called Lepteridine™, which has also been shown to have anti-inflammatory properties. There have been no clinical trials investigating the effects of manuka honey or Lepteridine™ on functional dyspepsia symptoms.

In this study we will compare the effects of consuming mānuka honey containing different amounts of Lepteridine™, over six weeks, on functional dyspepsia symptoms, inflammation, and quality of life. This study will also help us to design future studies on the effects of consuming mānuka honey on symptoms of functional dyspepsia to gain a fuller understanding of the benefits of mānuka honey on this condition.

Outcomes of the Study and associated data Primary outcomes - Symptom severity and quality of life indices specific to functional dyspepsia (Nepean Dyspepsia Index score) - Feasibility determined by a composite of the number of participants recruited and attrition rates. Associated data: Nepean Dyspepsia Index score, feasibility score Secondary outcomes - Composite gastrointestinal symptoms score using the Patient-Reported Outcomes Measurement Information System Questionnaire (PROMIS Gastrointestinal) - Anxiety scores using the Patient-Reported Outcomes Measurement Information System Questionnaire (PROMIS Anxiety) - Dyspepsia-related quality of life (Nepean Dyspepsia Index) - Epigastric pain score (Nepean Dyspepsia Index) - Postprandial discomfort score (Nepean Dyspepsia Index) - Stool form and frequency via daily bowel habit diary - Spontaneous symptom resolution (Nepean Dyspepsia Index score) - Faecal metabolome, metagenome, metagenome assemblies, bile and organic acid production - Composite cardiovascular risk profile - Plasma matrix metallopeptidase-9 - Blood immune markers - Blood inflammation markers - Postprandial appearance of manuka honey-derived compounds and metabolites Associated data: PROMIS Gastrointestinal, PROMIS Anxiety, dyspepsia-related quality of life, epigastric pain score, postprandial discomfort score, stool form and frequency, spontaneous symptom resolution, faecal metabolome/metagenome/metagenome assemblies, cardiovascular risk profile, plasma matric metallopeptidase-9, immune markers, inflammation markers, postprandial appearance of manuka honey-derived compounds and metabolites
