Filter by:Individuals with irritable bowel syndrome (IBS) may experience abdominal pain as a result of pain signals in the bowel and how these signals are processed in the brain. Studies using brain imaging (pictures) have shown that IBS patients with more pain diagnoses (i.e. fibromyalgia, migraines, etc.) have greater activity in the regions of the brain responsible for the emotional and thought processing of pain signals. This could possibly make bowel sensations and bowel difficulties feel abnormal or more noticeable, in turn causing more severe IBS symptoms. The purpose of this protocol is to explore the role of pain diagnoses and their affect on brain activity in IBS patients. The investigators will also examine the use of a medication, desipramine, which is known to affect these brain regions, in IBS patients.
Irritable bowel syndrome (IBS) is a very common, chronic disorder that significantly affects quality of life, and results in enormous expenditures each year in the United States. Therapy for IBS is generally unsatisfactory, and takes an additive approach whereby medications are prescribed according to each type of symptom the patient experiences. Accumulating evidence indicates that persons with IBS have a heightened perception of stress, and chronic stress has been shown to have a significant impact on IBS symptomatology. Mindfulness involves the ability to bring attention to the present moment without judgment; this ability is correlated with measures of mental health and decreased stress perception. The clinical literature suggests that mindfulness-based interventions may lead to improvement in many disorders including chronic pain, stress, anxiety, eating disorders and depressive relapse. The purpose of this study is to collect survey pilot data to determine whether an 8-week program of mindfulness-based stress reduction (MBSR) improves symptoms and quality of life for persons with IBS. Patients in the 8-week MBSR program are referred as part of their clinical care, and we seek approval only to collect survey data before and after the MBSR course. This study will evaluate whether there is sufficient evidence of efficacy to warrant a full clinical trial of MBSR.
This research is designed to study the reliability of the results of an AcuGraph in college students and faculty members with reported digestive symptoms
The study will recruit 80 out-patients diagnosed with Irritable Bowel Syndrome from a gastroenterological clinic. The recruitment will be consecutive with all patients receiving the diagnosis being offered to participate. After recruitment and 3 week baseline measure of IBS symptoms they will be randomised to either 10 weeks of internet delivered CBT or waiting list. After treatment IBS-symptoms are measured again to assess treatment effectiveness. All patients on waiting list are offered the same treatment as patients randomised to treatment. All patients are assessed 12 months after completion of treatment. Patients in treatment condition are hypothesized to experience significant reduction IBS symptoms and quality of life compared to patients on waiting list.
Objective: Randomized, double blind, placebo-controlled, crossover, clinical trial to examine the effects of the food additive glutamate (in the form of MSG) on IBS and fibromyalgia. Setting and Subjects: The Fibromyalgia Research Database at OHSU will be utilized to identify and recruit fibromyalgia patients who also have IBS to OHSU study centers. Intervention: Approximately 60 male and female subjects aged 18-75 will be placed on a 1-month glutamate-free elimination diet. Those that respond positively to the diet (we are estimating 30-40 subjects), will then be randomized to receive either a citrus drink containing 5 grams of MSG; or placebo (the citrus drink alone)on three consecutive days one week apart. The investigators are hypothesizing that those who react positively to the elimination diet will have symptom occurrence statistically more frequently when given the glutamate challenge, than when given placebo.
The purpose of the study is to evaluate the safety, tolerability, and effectiveness of LX1031 versus a placebo control in subjects with non-constipating irritable bowel syndrome.
The purpose of this study is: 1. To identify specific set of proteins in the cerebrospinal fluid (fluid surrounding the brain and the spinal cord), that are believed to be seen in Chronic fatigue syndrome (CFS) patients, but not in healthy controls (HC). A similar study that the investigators had conducted before,suggested that significant changes in proteins in the cerebrospinal fluid may be due to the fundamental pathology of this disorder. 2. Increased cerebrospinal fluid pressure (pressure that helps the cerebrospinal fluid to move around the brain and the spinal cord), may be related with certain symptoms like headache, sleep problems, light headedness, increased pain, excessive tiredness (fatigue) even with minimal work and memory problems. 3. Assessment of Autonomic Nervous system function (Sympathetic nervous system)between the CFS and HC. 4. Perform Lung Function Testing or pulmonary function test to estimate the lung capacities and score shortness of breath while performing breathing maneuvers. 5. Dolorimetry (18 tender point test) for assessment of pain threshold. 6. Capsaicin skin test 7. Allergy skin test
Fructo-oligosaccharides are known as prebiotic ingredients to modulate the composition of the intestinal microbiota and particularly to stimulate the growth of Bifidobacteria. Imbalance of the intestinal microbiota such as reduction of Bifidobacteria is implicated in Irritable Bowel Syndrome (IBS). Thus the objective of the study is to evaluate the effect of fructo-oligosaccharides to improve IBS score and to explore which modifications of the microbiota are responsible of this improvement.
Multi-centre, double-blind, randomised, placebo-controlled, parallel group study.
Irritable bowel syndrome (IBS) affects approximately 10-15% of the adult population. This condition is characterized by abdominal pain, altered bowel habit, abdominal bloating and reduced quality of life. Options for treating IBS include pharmacotherapy, psychotherapy, hypnotherapy and cognitive behavior therapy (CBT). Available data on the effectiveness of CBT in IBS patients in Israel are scarce. The aim of the present study is to assess effectiveness of CBT as compared with standard therapy for IBS patients in Israel The course of CBT consisted of up to six 40 min sessions, and included education about IBS and techniques to reduce focusing on symptoms and to manage stress.Standard therapy includs life style modifications. The primary outcome measure was the score on a symptom-severity scale specific to IBS.
