NCT ID: NCT06369753 Not yet recruiting - Clinical trials for Irritable Bowel Syndrome

Visible Abdominal Distension

Start date: September 2024
Phase: N/A
Study type: Interventional

Background. Abdominal distention is produced by an abnormal somatic postural tone. The authors developed an original biofeedback technique. In a randomized, placebo-controlled trial the authors demonstrated the superiority of biofeedback over placebo for the treatment of abdominal distention. However, the technique is technically complex and unpractical. Aim. To prove the efficacy of a noninstrumental biofeedback technique, transmitted by a standard training program, for the treatment of abdominal distension in different centers. Selection criteria. Episodes of visible abdominal distension. Intervention. Patients will be randomized into biofeedback and placebo groups. Three sessions of either biofeedback or placebo intervention will be performed during the first 3 weeks of the intervention period. Biofeedback: Patients will be taught to control abdominal and thoracic muscular activity by providing instructions using an original video support. In each center one operator will receive a standard training on how to deliver the noninstrumental biofeedback treatment. Patients will be instructed to perform the same exercises before and after breakfast, lunch and dinner during the 4-week intervention period. Placebo: Sham measurements of abdominal and thoracic motion will be performed, and a pill of placebo containing 0.21 g glucose will be administered; patients will be instructed to take a pill of placebo before breakfast, lunch and dinner during the 4-week intervention period.

NCT ID: NCT06365801 Not yet recruiting - Clinical trials for Irritable Bowel Syndrome

Investigation of Acupoint in Irritable Bowel Syndrome Based on Biological Characteristics

Start date: April 2024
Phase:
Study type: Observational

Irritable bowel syndrome (IBS) is a common functional disorder of the digestive system characterized by recurrent abdominal pain associated with bowel movements or changes in bowel habits. Although there are reviews and guidelines for treating IBS, the complexity and diversity of IBS manifestations make treatment difficult. By detecting and exploring the biological characteristics presented by the relevant meridian point reaction, this project clarified the specificity and regularity of the connection between the acupoint and the Zangfu reflected by this phenomenon, and conducted correlation analysis based on the intestinal flora, tryptophan metabolite levels and related scales of patients with IBS.

NCT ID: NCT06338189 Recruiting - Clinical trials for Irritable Bowel Syndrome

The 5Ad Diet for Functional Bowel Disorders

Start date: May 8, 2022
Phase: N/A
Study type: Interventional

The goal of this randomised controlled trial (RCT) is to compare the efficacy of the newly developed 5Ad diet against the widely researched low fermentable oligo-, di-, monosaccharide and polyols (FODMAP) diet in reducing gastrointestinal symptoms associated with functional bowel disorders/food intolerances. The primary aims of this RCT are to determine: - Whether the 5Ad diet is at least as effective as the low FODMAP diet in reducing gastrointestinal symptoms associated with FBDs/food intolerances. - Whether either the 5Ad diet or the low FODMAP diet are effective in reducing mental and physical fatigue. To achieve the above aims, an RCT will be conducted with the 5Ad diet in one arm vs the active phase of the low FODMAP diet in the other arm, in a cross-over design with a 7 days washout phase in between. Both dietary protocols will be followed by each participant for 7 days. Researchers will compare the results from the 2 dietary protocols in order to ascertain the superiority of one over the other in regards to 6 gastrointestinal symptoms (abdominal pain, bloating, flatulence, bowel urgency, straining and incomplete defecation), stool form and frequency of defecation.

NCT ID: NCT06325345 Not yet recruiting - Clinical trials for Irritable Bowel Syndrome

RCT of Gut-directed Hypnotherapy in Ehlers-Danlos Syndromes and Generalized Hypermobility Spectrum Disorders

Start date: April 1, 2024
Phase: N/A
Study type: Interventional

This randomized, controlled trial (RCT) will evaluate the effectiveness of gut-directed hypnotherapy for management of Irritable Bowel Syndrome (IBS) in individuals diagnosed with Ehlers-Danlos Syndromes or Generalized Hypermobility Spectrum Disorders (G-HSD). Consenting patients recruited from the Toronto General Hospital GoodHope Ehlers-Danlos Syndrome Clinic will be randomly assigned to one of two groups: (1) standard medical therapy or (2) standard medical therapy plus eight sessions of gut-directed hypnotherapy. The main questions this study will answer are: 1. Is gut-directed hypnotherapy an efficacious treatment for IBS symptoms among individuals with EDS or G-HSD? 2. Does gut-directed hypnotherapy improve other gut symptoms, quality of life, visceral sensitivity, and emotional distress? 3. Is the activity of the parasympathetic nervous system (i.e. the body's "rest and digest" system) associated with IBS symptoms or treatment outcomes among individuals with EDS or G-HSD? All participants will be asked to meet with a gastroenterologist three times as part of the standard medical therapy. At each physician visit, they will undergo electrocardiogram recording and complete self-report measures of gastrointestinal symptoms, quality of life, visceral sensitivity, and emotional distress. Participants randomized to receive gut-directed hypnotherapy will also eight weekly remotely-delivered sessions of gut-directed hypnotherapy delivered by a trained behavioral therapist in between the first and second physician visit. At each session of gut-directed hypnotherapy, a voluntary, pleasant, and dream-like state of deep relaxation will be induced and suggestions made for greater relaxation, abdominal comfort, and normalization of gut function. The first session will also include 30 minutes of education on the nature of the gut-brain axis and hypnotherapy prior to hypnosis. Researchers will compare study groups to see if participants who engaged in gut-directed hypnotherapy had greater improvement in IBS symptoms, other gastrointestinal symptoms, quality of life, visceral sensitivity, and emotional distress. Exploratory analyses will examine the relationships among heart rate variability, an index of parasympathetic nervous system activity, and study outcomes.

NCT ID: NCT06321237 Not yet recruiting - Clinical trials for Irritable Bowel Syndrome

Influence of Ear Vagus Nerve Stimulator on Patients With IBS

Start date: April 1, 2024
Phase: N/A
Study type: Interventional

Irritable bowel syndrome (IBS) is a very common functional digestive disorder characterized by chronic abdominal pain and altered bowel habits in the absence of biological or structural abnormalities. In the field of IBS, effective drug treatments are very limited, and patients are urgently looking for alternatives, including probiotics, hypnotherapy, osteopathy, dietary changes, and fecal microbiota transplants. In recent years, with the continuous elucidation of vagus nerve mechanisms, IBS patients are increasingly interested in bioelectrical regulation, and these patients are often skeptical of traditional drug treatment and believe that drugs are prone to side effects. For several reasons, vagus nerve stimulation (VNS) may be a promising option for improving IBS symptoms. In this experiment, the portable ear nail stimulator produced by Ruishen Medical can accurately stimulate the ear nail, transdermal stimulation of the ear vagus nerve, and give full play to its therapeutic effect. Therefore, the purpose of this clinical trial is to use ear nail stimulator in patients with IBS to explore whether it has therapeutic effects on patients with IBS. To explore the influence of tVNS therapy on irritable bowel syndrome compared with drug therapy, it is hoped that the use of TVNS therapy can reduce the use of related drugs, or even replace drugs. This study intends to recruit a group of patients with irritable bowel syndrome to use the portable ear nail stimulator, (1) to observe whether the symptoms of irritable bowel syndrome patients are improved; (2) To analyze the changes of intestinal microbes in patients with IBS; (3) Verify whether the level of intestinal inflammation is reduced and discover metabolic markers in the intestine.

NCT ID: NCT06318572 Recruiting - Clinical trials for Irritable Bowel Syndrome

Development of Self-administrable Psychological Intervention Programs Supported by New Technologies as a Treatment for Patients With Functional Digestive Disorders.

Start date: March 9, 2023
Phase: N/A
Study type: Interventional

Disorders of gut-brain interaction (DGBI) are produced by disturbances in the interplay between the gut and the central nervous system. Several psychological factors like anxiety, depression and altered coping are over-represented in these disorders. Recent surveys have shown that DGBI affect up to 40 % of the general population. Psychological interventions like cognitive behavioral therapy and hypnosis have been shown to be beneficial for managing these disorders. However, access to psychological interventions is very limited due to lack of resources to treat these very frequent conditions. OBJECTIVE: To determine the effects of psychological interventions using specifically developed therapeutic programs based on virtual reality, for telematic use at home, on symptoms severity, comorbidities, visceral sensitivity and intestinal dysbiosis in patients with DGBI. METHODOLOGY: After development of a program of psycho-education on DGBI using interactive immersion by means of virtual reality (VR) a randomized clinical trial will be developed. Consecutive patients will be randomized 1:1 to active treatment or placebo. In each patient in the active treatment group a session of psychoeducation using specifically developed VR-video leaded by a gastroenterologists, will be followed by telematic weekly group sessions of psycho-education leaded by a psychologist. During the 6 weeks of the treatment period patients will be instructed to perform self-administrable sessions of psychotherapy at home (by means VR). Patients in the placebo group willl take a placebo capsule daily. OUTCOME MEASURES. In all patients, severity of symptoms (primary outcome), QoL, somatic and psychological comorbidities (using specific questionnaires), visceral sensitivity (by means of a barostat) and microbiota analysis, will be performed before and at the end of the treatment period. Symptom severity will be assess also in follow-up phone calls at 3 and 6 months.
