Filter by:In this study the investigators aim to compare the efficacy of neomycin to a combination of rifaximin and neomycin in the treatment of C-IBS subjects with methane on their breath test. This study will be conducted in collaboration with Dr. John DiBaise at the Mayo Clinic in Scottsdale, AZ and Dr. Satish Rao in Georgia Regents University in Augusta, GA.
The objective of this study is to test the efficacy of a symptom management treatment strategy, namely, Acupuncture/Moxibustion (Acu/Moxa) to improve the symptoms associated with Irritable Bowel Syndrome (IBS) in persons between the ages of 18 to 70 years. IBS has been defined as abdominal pain or discomfort in the mid or lower gastrointestinal (GI) tract, associated with defecation or a change in bowel patterns and with features of disordered defecation. Current therapies include dietary modification, psychotherapy and pharmacological therapies. Traditional eastern approaches offer a therapeutic approach to symptom management that is subtle, holistic and holds promise as an intervention for IBS. This study will enroll 171 men and women experiencing IBS with diarrhea (IBS-D) defined by the ROME III criteria. Subjects will be randomized (by chance) to one of three experimental intervention conditions: Condition 1,subjects receive Standard Acu/Moxa; Condition 2, subjects receive Individualized Acu/Moxa and Condition 3, subjects receive Sham Acupuncture/Placebo Moxibustion(control group). Subjects will attend a screening/intake session followed by two treatment sessions per week for 4 weeks, one treatment session per week for 4 weeks, and 2 non-treatment follow-up sessions at weeks 12 and 24. All subjects will be assessed by a diagnostic acupuncturist (blinded to treatment assignments), receive interventions appropriate to their condition assignment by treating acupuncturists, be administered the same instruments, and submit their symptom diaries for data entry and analysis. All subjects will complete a prospective symptom diary for the duration of the study.
The purpose of this study is to determine the safety and efficacy of linaclotide administered to patients with Irritable Bowel Syndrome with Constipation (IBS-C).
Aims: 1. To pilot an randomized, controlled trial (RCT) to assess the effectiveness of the commonly prescribed medications in UK general practice for IBS: mebeverine (anti-spasmodic) and methylcellulose (bulking-agent) and of the patient CBT based self-management website. 2. To assess the level of support needed for patients using the patient CBT based self-management website for IBS (i.e., initial 30 minute telephone support session with a nurse and email support or not).
The purpose of this study is to determine whether the bacteria normally present in the bowels are different in people with constipation and to see what effect the treatment with the Food and Drug Administration (FDA) - approved drug, lubiprostone, has on these bacteria.
The goal of this study is to determine whether the oral administration of the probiotic VSL#3 under randomized, placebo-controlled conditions will improve symptoms of irritable bowel syndrome in children, safely.
The hypothesis was that a one-year experience of choir singing once a week is more beneficial than group discussions to saliva concentration of testosterone.
Brain-derived neurotrophic factor (BDNF), originally known to be a member of the nerve growth factor family, has aroused attention as a modulator in visceral hyperalgesia recently. Visceral hypersensitivity is recognized as a clinical hallmark in IBS patients. So in this study, the investigators will focus on the role of BDNF in colonic hyperalgesia in IBS patients.
Fecal calprotectin is a very sensitive non-invasive inflammation marker in the detection of inflammatory bowel disease and, to a lesser degree, has also proven to be useful in adenomatous polyps, neoplasias, and infectious gastroenteritis. Elevated calprotectin levels can also be found in patients with lesion only in the upper gastrointestinal tract. However, the diagnostic value of calprotectin has never been tested in this setting. The aim of the study is therefore to determine the diagnostic value of fecal calprotectin in patients with diseases of the upper gastrointestinal tract.
Sacral nerve stimulation (SNS) has become a well-established treatment for patients with fecal incontinence since 1995. The mechanism of action of SNS is still not fully understood but recent studies have shown that the motility of the whole colon is modulated during the stimulation. This modulation of the colonic motility could be a potential mechanism of an action to relieve the symptoms in patients with IBS. Twenty eight patients with IBS will be enrolled in the study. They have to meet the ROME III criteria, and also satisfy the criteria for implantation of a neurostimulator. After a post implantation period where the programming of the neurostimulator is optimised, the patient is randomized in a double blinded design to receive either ON-OFF or OFF-ON stimulation in a 2-month period. At the end of each period (ON/OFF) the patient will be examined with Magnet Tracking System (MTS) for motility and with impedance planimetry including thermal stimulation (circulating water)for multimodal sensory testing of the rectum. This is based on the study hypothesis that the motility of the small intestine and the colon is changed in IBS patients according to their subtype (Diarrhoea-IBS, Constipation-IBS and Disordered bowel habit-IBS) compared to healthy persons. And that SNS will affect the motility of the small intestine and the colon in IBS patients as well as SNS will affect the perception of pain/discomfort in the rectum in IBS patients. The effect of ON-OFF-sacral nerve stimulation on the IBS patients and thereby their IBS symptoms will also be evaluated by an IBS score (GSRS-IBS)and on quality of life by an IBS Impact Scale (IBS-IS) as well as the significance of placebo effect in the treatment of patients with IBS with SNS will be evaluated.
