About this study

Official title: Impact of Bread Diet on Intestinal Dysbiosis and Irritable Bowel Syndrome Symptoms in Quiescent Ulcerative Colitis: A Pilot Study

The present study aimed to compare the in vivo prebiotic properties of bread produced by traditional breadmaking techniques with that made using a modern breadmaking method on Irritable Bowel Syndrome-like symptoms in patients with quiescent Ulcerative Colitis. The expected outcome of the differential effects was a change in the faecal microbiome composition, which may indicate changes in the mucosa-associated microbiota.

What is being measured

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

  1. Changes in IBS-like symptomatology

    Changes in IBS-like symptomatology were tested by IBS-Symptom Severity Score. The overall IBS-SSS score was calculated by totalling the punctuation of its five items. Each ranged from 0 to 100: (i) abdominal pain, (ii) number of days of abdominal pain during the last 10 days (number of days with abdominal pain x10), (ii) abdominal distension, (iv) satisfaction of defecatory behaviour, (v) interference of IBS symptoms in life. The possible range was then 0-500.

    Measured: Measurements were assessed at baseline (T0) and eight weeks (T1)

Secondary outcomes (1)
  1. Changes in the abundance of bacterial markers

    Shifts of abundance of Eubacteria (EUB), A. municiphila (AKK), M. smithii (MSM), Bacteroidetes (BAC), Ruminococcus sp. (RUM), F. prausnitzii (FPRA) and E. coli (ECO) levels will be measured prior (T0) and after the intervention (T1). Results will be expressed as 16S gene copies of microbes per gram of faeces

    Measured: Measurements were assessed at baseline (T0) and eight weeks (T1)

Questions about this trial

What is this clinical trial studying?

A study of Ulcerative Colitis in Remission, run by Institut d'Investigació Biomèdica de Girona Dr. Josep Trueta at 1 site in Spain.

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 20 Dec 2022. 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 Spain. 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. Some participants in this study may receive a placebo. 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?

Changes in IBS-like symptomatology (time frame: Measurements were assessed at baseline (T0) and eight weeks (T1)). 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 NCT05656391, which also lists 1 linked publication.

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 20 Dec 2022.
