An observational study to evaluate LOTRONEX® in women with severe IBS-D in the current clinical practice setting.
The purpose of this study is to investigate the frequency and severity of chronic pelvic pain (CPP) in adult women living in Copenhagen Country and Zealand Country (total population 2,4 million), Denmark, in relation to selected factors, such as basic demographic and clinical factors, health related quality of life, physical activity and abnormal muscular findings in the pelvic area.
Irritable bowel syndrome (IBS) affects about 15% of the U.S. population. There are still no effective and safe medications approved for the treatment of abdominal pain associated with bowel symptoms in IBS. This study will investigate the effects of an approved medication, Dronabinol, on the movement of food through the stomach and colon in subjects with a history of diarrhea-predominant Irritable Bowel Syndrome (D-IBS). Dronabinol is a synthetic medication (a medication made in a laboratory) related to the active ingredient of "cannabinoid or marijuana". Dronabinol is approved by the Food and Drug Administration (FDA) for preventing nausea and vomiting in patients with cancers undergoing chemotherapy. It is also used in AIDS patients with excessive weight loss for improvement in appetite and weight gain. The hypothesis in this study is that dronabinol will slow down the movement of food through the colon, and that this effect is regulated by the genes controlling the body messengers (receptors) that respond to medicinal marijuana or synthetic medicines that work on the same messengers that are present in the gastrointestinal tract and pain nerves.
The purpose of this study is to investigate the association between gut microbiota, immunology and typical pathophysiological factors in patients with IBS (all subtypes) AND to assess the effect of Activia consumption on GI symptoms provoked by a lactulose challenge test in IBS patients.
The primary goal of the study was whether gut focused hypnotherapy, in a group format, was successful in reduction of symptoms in patients with irritable bowel syndrome. The secondary goal was to see if any outcome predictors could be determined.
The purpose of this study is to determine whether alpha-galactosidase enzyme is affective in alleviating the symptoms of irritable bowel syndrome (IBS).
Discriminating irritable bowel syndrome (IBS) from inflammatory bowel disease (IBD), especially with mild disease activity, is common clinical challenge. Most of the patients with suspected IBS have to go invasive procedures (colonoscopy/gastroscopy). In order to avoid invasive investigations, there is a search for noninvasive markers with the capacity to distinguish between IBS and IBD. Dr Hossam Haick (Department of Chemical Engineering, Technion) developed a system that combines nano-metals produced in his laboratory with electrical devices (transistors). The combination between a nanomaterial and an electrical transistor induces a change in its electrical behavior upon exposure to the material being examined; that is, a change in its electrical properties. The change in its electrical behavior is translated into a computerized graphic signal. The electronic nose is composed of an air pump, a filter for filtering external contaminants and an array of sensors. Each sensor transmits a signal according to the materials it "knows" how to identify. Thus, it is possible to characterize most of the substance families characteristic of a certain disease, and the same system is designed for differential diagnosis of different diseases. The purpose of the investigators study is to use the "electronic nose" to find bio-markers that will help to diagnose IBD and IBS without using invasive procedures. The plan is to collect 200 samples (50 IBS' 50 Crohn's disease, 50 ulcerative colitis and 50 controls). The patients included in the study will undergo an evaluation by a gastroenterologist after signing an informed consent and will answer a questionnaire. The samples will analyzed in the laboratory of Dr. Haick.
A study to verify the superiority of ramosetron hydrochloride (Irribow Tablets) to placebo for male patients with diarrhea-predominant irritable bowel syndrome (D-IBS) and to evaluate its safety.
Background: Abdominal bloating is a frequent and bothersome complaint in patients with functional gut disorders without satisfactory treatment to date. Recent data from our laboratory indicate that abdominal distention in these patients is produced by abdomino-phrenic dyssynergia: diaphragmatic contraction associated with abdominal wall relaxation (particularly the internal oblique). In analogy to other clinical situations (e.g. functional outlet obstruction, rumination or aerophagia) behavioral treatment by means of biofeedback might be equally effective in these patients. The investigators hypothesized that abdomino-phrenic coordination and abdominal distention can be controlled by biofeedback techniques. Aim: to prove the efficacy of behavioural treatment using biofeedback techniques for abdominal distension. Randomization: Patients will be randomized into biofeedback and placebo groups. Intervention. Biofeedback: patients will be taught to control abdominothoracic muscular activity by bio-feedback using online electromyography information. Placebo: patients will be given a pill containing placebo medication. Interventions will be delivered in 3 sessions (20 min each) over 10-day period . Measurements: Sensation of abdominal distension will be assessed by means of graphic rating scales graded from 0 (no perception) to 6 (very intense sensation). The activity of the abdomino-thoracic muscles will be recorded. Abdominal distension will be measured by a metric tape fixed to a non-stretch belt placed over the umbilicus. Outcomes: Primary outcome: Change in sensation of abdominal sensation. Secondary outcomes: a) changes in thoraco-abdominal activity of the muscular walls; activity of thoraco-abdominal muscles (intercostals, diaphragm, external oblique, internal oblique, upper rectus, lower rectus) will be measured by electromyography; b) changes in girth; abdominal girth will be measured using a nonstretch belt (48mm wide) that is placed over the umbilicus. The overlapping ends of the belt will be adjusted carefully with two elastic bands to adapt constantly to the abdominal wall.
