Brief summary in lay language

This study examines a personalized therapy for patients with irritable bowel syndrome. Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders and affects about 5-11% of the adult population worldwide. Symptoms of IBS include recurrent abdominal pain associated with an alteration of bowel habits. The disease is understood as a disturbance of the "microbiota-gut-brain axis", including changes in pain perception, emotional perception or the microbiome. Therapeutic options for IBS range from the use of medication, to dietary measures, to specific psychotherapy manuals. To date, none of the therapies have made a breakthrough in IBS. This may be explained by differences in the patients with IBS, themselves. Research has shown that patients with IBS are a very diverse group, including differences in somatic and psychic patterns and their relationship. To address these differences, this study will test a personalized therapy. For this purpose, patients with IBS will be characterized according to their psycho-somatic profile and subsequently assigned to a therapy. The patients will receive either an optimal personalized therapy, a sub-optimal personalized therapy, or an enhanced standard treatment (i.e., a control). The primary aim of the study is to assess the feasibility of personalized therapy in the treatment of IBS. The secondary aim of the study is to gain an insight into the relative effectiveness of optimal personalized therapy.

Brief summary in scientific language

This study is a pilot RCT-study for a personalized therapy for patients with IBS. The study is planned as a three-arm study: Treatment group A: Optimal personalized therapy Treatment group B: Sub-optimal personalized therapy Control: Enhanced standard treatment A psycho-somatic profile will be constructed for all participating patients using entries in an online diary initiated prior to the start of the study. In addition, somatic parameters including the microbiome, heart rate variability and pain threshold (measured with a blood pressure cuff) will be documented for all participating patients before the start, during and after the study. The primary aim of the study is to assess the feasibility of personalized therapy in the treatment of IBS. The secondary aim of the study is to gain an insight into the relative effectiveness of optimal personalized therapy.

Interventions, Observational Groups

Arm 1:
Treatment group A: Optimal personalized therapy Continuation of ongoing treatment with additional optimal personalized therapy. Depending on and according to the psycho-somatic profile of the individual patient EITHER: Group therapeutic abdominal hypnotherapy weekly for 60 min for 7 weeks OR: Individual therapeutic EMDR treatment (Eye-Movement Desensitization and Reprocessing) weekly 60 min for 7 weeks.
Arm 2:
Treatment group B: Sub-optimal personalized therapy Continuation of ongoing treatment with additional sub-optimal personalized therapy. Depending on and according to the psycho-somatic profile of the individual patient optimal therapies will be reversed. Those deemed best suited to group therapeutic abdominal hypnotherapy will be treated with EMDR. Conversely those deemed best suited to EMDR will be treated with Group therapeutic abdominal hypnotherapy.
Arm 3:
Control: Enhanced standard treatment Continuation of ongoing treatment with additional telephone counselling (once a week, 5-10 min for 7 weeks).

Endpoints

Primary outcome:
Feasibility of the study at the end of treatment The feasibility criterion is considered to be met if a sufficient number of patients agree to participate in the study and if 70% of the original participants remain part of the study until its conclusion.
Secondary outcome:
An insight in the effectiveness of optimized personalized therapy will be gained according to the following: • Simultaneous and time-depended relationships between somatic and psychological parameters during the study and at follow-up, measured according to entries in online diaries. • Reduction of symptom severity and illness anxiety measured by IBS-SSS (irritable bowel syndrome severity scoring system) and WI-7 (whiteley index 7) in pre-post comparison and at follow-up. • Improvement in quality of life, measured according to the FDD-Qol (Functional Digestive Disorders Quality of Life) in pre-post comparison and at follow-up. • Reduction in anxiety and depression-related symptoms, measured according to the PHQ-9 (Patient Health Questionnaire 9) and the GAD-7 (Generalized Anxiety Disorder 7) in pre-post comparison and at follow-up. • Change in somatic parameters (microbiome, heart rate variability, pain threshold) in pre-post comparison and at follow-up.
