View clinical trials related to Irritable Bowel Syndrome.
Filter by:Children and adults commonly suffer from recurrent abdominal (stomach) pain. One type is called irritable bowel syndrome (IBS). IBS in adults and children is one of the most common and costly health care problems in the US. Some children have pain frequently (recurrent pain) while others rarely have pain. The investigators are conducting this study to help us answer questions about the causes and treatments, and management of IBS in children. The purpose of this study is to find out if there is more than one type of IBS in children. If there is, this will be important in deciding the best treatments. The investigators also want to learn how children with IBS differ from those who do not have recurrent abdominal (stomach) pain.
The purpose of this study is to test whether disease-related expressive writing is effective in the treatment of Irritable Bowel Syndrome (IBS).
This randomised controlled trial (RCT) aimed at assessing the efficacy of hypnotherapy in group sessions (GHT) with a 12-months follow-up.
The purpose of this study is to determine the daily dose of mesalamine granules that will provide adequate relief from symptoms of IBS with diarrhea.
The Canadian College of Naturopathic Medicine is conducting a research study on Irritable Bowel Syndrome (IBS), a common condition in North America. It is a long term, recurring gastrointestinal disorder that is estimated to affect 30% of the general population. IBS is characterized by abdominal pain and cramps, and bowel dysfunction such as diarrhea and bloating. The medicines that are currently used to help people with IBS are not as effective as we would like them to be. These medicines are usually only prescribed to reduce the pain of IBS and not actually treat the disorder itself. Recently, scientists have found that probiotics (beneficial bacteria that live inside humans) may help reduce the painful symptoms and diarrhea that are part of IBS. This research is being conducted to determine whether this particular combination of three probiotic bacteria (named Lactobacillus gasseri, Bifidobacterium bifidum and Bifidobacterium longum) will reduce the symptoms of IBS.
The aim of this study is to investigate the efficacy of a 10 week Internet-delivered CBT treatment for patients diagnosed with IBS. The patients' work with the treatment and is supported through online contact with a therapist. Approximately 86 patients will be included in the study and randomized to either condition. All included patients are assessed one week before the treatment starts. After 10 weeks (post treatment). Follow-up assessments are conducted at 3 and 12 months follow-up after treatment. Patients in treatment condition are hypothesized to experience significant reduction IBS symptoms, societal costs and quality of life compared to patients on waiting list.
Irritable bowel syndrome (IBS) causes many symptoms, including abdominal pain, irregular bowel movements and bloating. It may be caused by loe degree inflammation of the intestine. The ingredients of coltect which contains green tea, selenium, and curcumin have been proven very safe and have anti inflammatory and anti oxidant activity. The aim of the study is to see whether the use of Coltect can improve symptoms in IBS patients.
The aim of this study is to develop and validate a questionnaire (non-invasive technique) to identify patients who are hypervigilant for noxious visceral sensations and who show a lower threshold to report pain. This questionnaire would be useful in studies investigating the role of visceral pain hypervigilance and pain sensitivity in the comorbidity of IBS with other somatic disorders.
The purpose of this research study is to determine how Lubiprostone, a medication used to treat irritable bowel syndrome with constipation predominant symptoms (IBS-C), works to reduce clinical pain. Lubiprostone acts in the small intestine to cause an increase in the secretion of chloride, water and sodium. The increased fluid causes food residue to move through the bowel more quickly and makes the stools softer. First, we want to test the idea that Lubiprostone works by making a person less sensitive to pain. Second, we want to confirm that Lubiprostone decreases the time it takes fecal matter to travel through your GI tract, referred to as transit time.
Irritable bowel syndrome (IBS) is a common disorder which presents with abdominal pain or discomfort in association with altered bowel habit. IBS is further subcategorized as three types according to the predominant bowel movement pattern: IBS with constipation (IBS-C), IBS with diarrhea (IBS-D), and mixed-IBS (IBS-M). The exact causes of IBS remain incompletely understood, but proposed mechanisms include abnormal motility, visceral hypersensitivity, abnormal brain-gut interactions, psychological distress, and altered GI tract motility. Lubiprostone, a novel drug that works by activating the colonic ClC-2 chloride channel, has been approved for use in patients with chronic idiopathic constipation and recently approved for the treatment of IBS-C in women aged 18 and older. By activating the ClC-2 chloride channel in the colon, lubiprostone allows more fluid secretion into the intestinal lumen which leads to softer stool consistency. In phase III clinical trials, patients with IBS-C receiving lubiprostone have reported improvements in many symptoms such as abdominal pain and constipation. However, there is limited physiologic data to explain how exactly lubiprostone improves IBS-C symptoms. The Smartpill is a novel non-digestible capsule that is capable of measuring intraluminal pH, pressure, and temperature in the gastrointestinal (GI) tract. Smartpill has been shown to accurately measure whole gut as well as regional (i.e. stomach, small bowel, colon) transit time. The primary aim of this study is to determine the effects of lubiprostone on whole GI tract transit, colonic transit, motility, and intraluminal pH in patients with IBS-C through evaluation with the Smartpill. The investigators propose to study the effect of lubiprostone vs. placebo on these parameters, and secondarily to evaluate changes in these parameters with differing doses of lubiprostone. The investigators hypothesize that lubiprostone will increase whole GI and colonic transit compared to placebo in patient with IBS. the investigators do not expect a change in intraluminal pH with lubiprostone compared to placebo.
