Active clinical trials for "Irritable Bowel Syndrome"

The purpose of the study is to determine the efficacy and safety of Rezular (arverapamil) in the treatment of IBS-D.

Hypotheses: Primary null hypothesis: The rate of clinical response, assessed as patient-reported global symptom rating and "adequate relief of IBS symptoms," does not differ between non-depressed IBS patients treated with the SSRI citalopram and patients treated with placebo. Secondary null hypotheses: Changes in disease-related quality of life, assessed with the IBS-QOL instrument, do not differ between patients treated with the SSRI citalopram and patients treated with placebo. Changes in rectosigmoid visceral sensitivity, assessed by barostat balloon distention, do not differ between patients treated with the SSRI citalopram and patients treated with placebo.

Objectives : To investigate the analgesic effects of repeated sessions of unilateral rTMS in patients with chronic pain syndrome due to fibromyalgia, IBS or burning mouth syndrome. Primary outcome will be numerical pain scores. Methods : The study will be randomized and performed in parallel groups and double blind versus sham stimulation, and will include 90 patients (45 patients per treatment arm). The randomization will be computerized and performed for each aetiological group separately. The rTMS will be performed on the left motor cortex, 5 consecutive days , then once a week during 3 weeks then twice a month during 2 months, then once a month during 6 months. Clinical assessment will include an assessment of pain, quality of life, sleep, depression and anxiety, catastrophizing, and a neuropsychological evaluation. Conclusion : this study should allow to determine for the first time the long term efficacy and safety of rTMS in the treatment of dysfunctional or idiopathic chronic pain syndromes which are often refractory to conventional treatments.

This study will examine the efficacy, safety and tolerability of different oral dose of YM060, 5-HT3 receptor antagonist, in patients with d-IBS.

The purpose of this study is to determine whether acupuncture is effective in reducing the symptoms of irritable bowel syndrome (IBS).

The purpose of this study was to determine the dose-ranging efficacy and safety profile of encapsulated Bifidobacterium infantis 35624 in female subjects with irritable bowel syndrome (IBS).

The purpose of this study is 1) to determine whether a comprehensive self-management intervention is effective in a sample that includes men and women with irritable bowel syndrome, and 2) to determine whether the comprehensive self-management intervention is as effective when delivered over the telephone as compared to a face-to-face approach.

The goal of this clinical trial is to compare the efficacy of four different drugs in combination for management of irritable bowel syndrome (IBS)-associated diarrhea. The main question to answer is: Is there a significant difference in effect of different drug combinations in management of irritable bowel syndrome with diarrhea? Participants will be divided into 3 treatment groups. Each group will be given a combination of drugs for 2 weeks At the end of study, efficacy of different drug combinations and their potential side effects will be compared between the treatment groups

Study to asess the effects of Iberogast® (STW5) and Iberogast® N (STW5-II) in intestinal gas transit and abdominal symptoms of patients suffering from irritable bowel syndrome or functional dyspepsia.

This study aims to compare visceral rectal sensitivity and quality of life of 40 Irritable Bowel Syndrome women, with (20) and without sexual dysfunction (20). Both Irritable Bowel Syndrome (IBS) and sexual dysfunction (SD), decrease quality of life (QOL) separately, and only recently we have shown that quality of life decreases even more with both diseases. Thus, there is clinical evidence to search for a biological marker that explains this cumulative effect. Investigators will determine IBS using the Rome IV criteria, SD through the Female Sexual Function Index (FSFI) while and QOL through the Short Form-36 and the IBS-QOL. Visceral sensitivity will be evaluated by a barostat study: A small bag connected to a computer is placed in the rectum. This computer will insufflate air increasing the volume and simultaneously record the pressure inside the rectum; therefore investigators can simulate what happens when the stool reaches the rectum. The patient reports the first sensation, gas sensation, need to defecate and even pain. For patient protection the pressure will never exceed 50 mmHg and/or if any amount of pain is reported. To assess the effect of food on this visceral sensitivity, it is performed in 2 stages, fasting and 30 minutes after a standardized meal. The protocol will be carried out through 3 visits. First patients will be recruited; the diagnosis of IBS, SD, quality of life will be established and basic laboratory tests will be schedule before next visit. Second visit will be on day 7 of the menstrual cycle when investigators will carry out the barostat study and determination of blood´s sex hormones. The last visit is for the second barostat study on day 21 of the menstrual cycle with sex hormones measurement. This protocol will compare: Rectal pressure and volume for tone, first sensation, gas sensation, desire to defecate and pain, measure during fasting and postprandial periods in day 7 and 21 (estrogenic and progesterone phase) of the menstrual cycle. Other variables include (age, marital status, disease history, SF-36, IBS-QOL, etc.). This study aims to find a biological marker to explain the low QOL observed in daily clinical practice. This approach will allow us a more effective diagnosis and perhaps the creation of more effective therapeutic approaches to treat these patients. In the long term, we expect to establish the foundations of a patient-centered medicine with shared decision more effective in the gut brain axis disorders.
