Filter by:The purpose of this study is to explore and examine endpoints that allow evaluation of the "clinically significant improvements, focusing on the patient's chief complaint and the severity of major IBS symptoms" by this drug in patients with diarrhea-predominant irritable bowel syndrome (IBS).
The study hypothesis is that the naturally occurring bile acid, chenodeoxycholic acid, induces acceleration of colonic transit in health and in patients with constipation-predominant Irritable Bowel Syndrome (IBS-C).
Our hypothesis is that the medication approved for treatment of high blood cholesterol levels, Colesevelam HCl (WELCHOL), decreases colonic transit and permeability in patients with diarrhea due to irritable bowel syndrome. This effect is thought to result from the effect of the medication on bile acids, which can cause diarrhea.
The aim of this study is test the efficacy of a comprehensive self-management therapy to decrease abdominal pain/discomfort and improve quality of life in patients with irritable bowel syndrome (IBS) compared to IBS patients receiving their usual care.
Irritable bowel syndrome (IBS) is a very common chronic functional gastrointestinal disorder characterised by abdominal pain/discomfort, bloating and alterations in bowel function. This condition significantly impairs quality of life and places a large burden on health care resources. Existing therapies for IBS are far from being satisfactory and new therapies are being constantly sought. The pathogenesis of IBS remains unclear. Imbalance in the intestinal microbiota is considered to be one important etiologic factor for IBS. That some probiotics are effective in the prevention and treatment of IBS supports this idea. Progut is a synbiotic: a combination of probiotics and prebiotics. Probiotics are viable beneficial bacteria that are normally present in a healthy digestive tract. Each capsule of Progut contains 9 billion viable bacteria from 8 different strains that are characteristics of a healthy normal gut microflora: Lactobacillus (L. acidophilus, L. casei, L. lactis, and L. bulgaricus); Bifidobacterium (B. longum, B. infantis and B. bifidum); and Streptococcus thermophilus at time of manufacturing. To ensure survival of these bacteria, Progut is encapsulated and enteric-coated. The primary objective is to evaluate the tolerability of Progut treatment 1-3 capsules/day in patients with irritable bowel syndrome under the same conditions as those likely to be encountered in a standard general clinical practice or outpatient clinic. The rationale for this study is to obtain tolerability data in patients with IBS in the Singapore. The secondary objectives are to evaluate the patients' satisfaction and symptom improvement with Progut treatment.
Irritable bowel syndrome (IBS) is the most common digestive disorder that affects more than 5% of population in Hong Kong. However, there is no effective treatment of IBS using Western Medicine. Acupuncture, a traditional therapeutic modality, has been used in China for thousands of years for various pain disorders. In addition to analgesia, acupuncture has also been shown to influence physiology of gastrointestinal tract. The investigators set out to evaluate the therapeutic value of acupuncture in IBS. The investigators will study its effects on rectal sensation and brain activity in patients with IBS. All patients will be evaluated for study eligibility at visit 1 (baseline). Baseline assessment includes individual IBS symptoms (pain/discomfort, bloating, constipation, and diarrhea) as perceived by patients will be scored. The syndrome of IBS patients will also be recorded and analyzed based on the Chinese medicine theories. All patients will then undergo baseline rectal barostat for thresholds of rectal sensation. At visit 2, eligible patients will be randomly assigned to either (1) electroacupuncture or (2) sham electroacupuncture treatment groups. Functional Magnetic Resonance Imaging (fMRI) scanning will be performed before, during and after the electroacupuncture or sham electroacupuncture treatment.
The purpose of this study is to evaluate the efficacy of confocal laser endomicroscopy in assessment of colonic permeability against conventional sugar absorption test.
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
