Filter by:The purpose of this study is to determine if RVX-100 is safe and effective in treating acute abdominal pain in patients with irritable bowel syndrome accompanied by diarrhea.
The proposed pilot project for this seed grant focuses on the role of intestinal serine-proteases in the pathogenesis of diarrhea-predominant IBS (D-IBS). In this study we will further assess serine-protease activity in patients with D-IBS and also explore a possible mechanism by which these proteases can lead to alterations in intestinal physiology and symptoms in these patients. The general hypotheses for the proposed research are that (A) the levels of fecal serine-protease in patients with D-IBS are abnormally increased (B) this abnormal serine-protease activity leads to/is associated with an abnormal increase in intestinal permeability and therefore enables (C) chronic stimulation and activation of the mucosal immune system in these patients. In addition, it is aim to determine whither periodontal inflammation is associated with intestinal permeability and serine protease activity.
The research project addresses the following hypotheses (A) the normal balance of beneficial and detrimental commensal intestinal bacteria is deranged in IBS, with selective alterations in clinically defined patient subsets i.e., diarrhea predominant IBS (D-IBS) and post-infectious IBS (PI-IBS); (B) these changes in intestinal microflora are associated with sub-clinical mucosal inflammation and activation of the mucosal immune system; and (C) activation of the mucosal immune system leads to alterations in gastrointestinal (GI) functions (i.e., motility and sensation) and functional symptoms.
Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder haracterised by abdominal pain or discomfort associated with altered bowel habits,while the mechanism is still not understood.Recent advances have conceptualized the faecal supernatants of diarrhoea-predominant IBS have a substantially higher serine protease activity, while in china,almost no studies have reported about protease activity in IBS.
This trial will study the effects of an investigational (not FDA approved) medication, ROSE-010, on the movement of food through the stomach, small intestine and colon in females with constipation predominant irritable bowel syndrome (C-IBS). The study hypothesis is that ROSE-010 will delay gastric emptying of solids and enhances gastric accommodation without retarding colonic transit in female patients with C-IBS.
The study aims to compare two manualized treatments. They are based on cognitive behavior therapy or stress management. Both treatments are delivered via an internet application and the patients' work with the treatments is supported through online contact with a therapist. The treatments last for 10 weeks. Approximately 200 patients will be included in the study and randomized to either condition. The study hypothesis is that CBT will be superior to stress management on the main outcome measure, which is IBS symptom severity measured over 4 weeks.
The specific aim of this proposed pilot study is to compare two standardized processes (paper and electronic) to deliver a customized MedlinePlus health information prescription.
Background: Functional gastrointestinal disorder (FGID) is the most common gastrointestinal disease in daily clinical practice. The disease is symptomatic but has no identifiable cause by standard diagnostic tests such as endoscopy. It is characterized by its frequent relapses and thus the disease causes a significant level of stress and anxiety to patients. Due to the complexity and chronicity of the disease, it is believed that appropriate counseling on the nature and management of the disease is necessary to decrease patient's anxiety level and improve quality of life. Indication: Patients who have symptoms suggestive of FGID including non-erosive gastroesophageal reflux disease (NERD), functional dyspepsia (FD) or irritable bowel syndrome (IBS). Aim: To validate the effectiveness of counseling in patients suffering from FGID. Method: Patients recruited to the study will follow the usual management of patients attending the Gastroenterology specialty clinic in Prince of Wales Hospital. Standard blood tests and endoscopy will be performed. Standard medication will be given to the patients for 8 weeks after endoscopy and the patients will come back to the specialty clinic for a final visit. The patient will be given an "on-demand follow up within 1 year" option at final visit. The patient will decide if he/she wants to come back to our specialty clinic to follow up his/her problem within one year. Follow-up after Final Visit Follow-up questionnaires will be mailed to patients 6 months, 1 and 2 years after Final visit. Randomization: All the patients will be randomized into two groups in First Visit: 1) Control group, and 2) Counseling group. Both groups of patients will follow the above protocol, except that 2 extra counseling sessions will be arranged for the Counseling group immediately after visiting the physician.
In the investigators study, the investigators will focus on the screening of the related proteins and miRNA to IBS in order to reveal the possible clues or molecular mechanism for this disorder.
Patients suffering from Irritable Bowel Syndrome with predominant constipation will be provided with the study medication. The study medication will be evaluated for its efficacy in relieving the symptoms
