About this study

Longitudinal Investigation of intestinal microbiome, fecal inflammation markers, stress and psychological variables in patients with irritable bowel syndrome and inflammatory bowel disease undergoing gut-directed hypnotherapy (GHT).

Read the detailed description

Study design is a within-subject design with assessment at 4 points in time. Data will be collected 3-1 month before first GHT session (T1), immediately before first session (T2), at the last session (T3), and 3-6 months after last session (T4).

Study patients will be recruited consecutively at the special outpatient-clinic for psychosomatics at the division of Gastroenterology and Hepatology, department for Internal Medicine III, University Hospital Vienna.

Patients undergo GHT in group setting, which has been shown to reduce irritable bowel syndrome (IBS) symptoms and to increase psychological wellbeing. The GHT protocol used will be the Manchester protocol of gut-directed hypnotherapy and consists of 10 weekly sessions (45 minutes) with six up to eight patients per group over a treatment period of 12 weeks.

The following variables will be assessed using standardized questionnaires: anxiety and depression (HADS-D), perceived stress (PSQ), resilience (CDRISC), and quality of life (visual analogue scales). IBS symptoms will be captured by the IBS Severity Scoring System (IBS-SSS), inflammatory bowel disease (IBD) disease activity via Harvey-Bradshaw-Index. Additionally, medication intake and food supplements will be assessed.

Microbiome data will be gained by frozen stool samples, collected by patients at home. Patients will be provided with a delivery kit to keep the samples frozen. Patients are asked to collect the first stool of the day and not to change diet, medication and intake of pre/probiotics during the hole study period, if possible (documented). At each time point (T1-T4) patients are ask to bring two immediately frozen (stored in their home freezer) double samples (2 stool samples within 1 week) to the hospital to be immediately stored at minus 20 degree Celsius. If patients do not have a home freezer, stool will be collected and frozen at the hospital.

Planned analyses comprise longitudinal and cross-sectional comparisons Intestinal colonization will enter in the analyses according to an algorithm assigning values for an increase or reduction of dysbiosis. Dysbiosis is hereby defined by the following markers: reduction of fecal biodiversity, lowered occurrence of the species Bifidobacterium, Lactobacillus and Faecalibacterium prausnitzi, increased occurrence of Enterobacteriaceae, and a higher quotient Firmicutes:Bacteroidetes.

Questions about this trial

What is this clinical trial studying?

A study testing Gut-directed hypnotherapy in people with IBS and IBD, run by Medical University of Vienna at 1 site in Austria.

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 2 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 5 Oct 2016. 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 Austria. 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?

Changes in gut microbiome as assessed through analyzing fecal samples (time frame: 7 days). The study lists 3 primary outcomes in all. 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 NCT02536131, 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 5 Oct 2016.
