Filter by:The Purpose of the study is to determine the efficacy of Kleen Enema® (Phosphate Enema) for bowel preparation in out-patients under going sigmoidoscopy procedure and to evaluate the safety behavior of Kleen Enema® in outpatients requiring sigmoidoscopy
Irritable bowel syndrome is characterized by abdominal discomfort and bowel habit change. It is increasing worldwide. But the pathophysiology of the irritable bowel syndrome is not proven. So, the treatment's target is the relief of the symptoms. Small intestinal bacterial overgrowth considered as the cause of the irritable bowel syndrome. Because, it is related to the postprandial abdominal discomfort and the abdominal discomfort could be relieved after taking antibiotics. There are several diagnostic methods for small intestinal bacterial overgrowth. hydrogen breath test is non-invasive method for diagnosis of the small intestinal bacterial overgrowth. But, there is no standardized cut-off value for the hydrogen breath test. So, we want to compare the hydrogen breath test between the irritable bowel syndrome patients and normal people. And then, we want to analyze the efficacy of hydrogen breath test for the diagnosis of irritable bowel syndrome.
The patients having a syndrome SII would be more intolerant in the fructose than the healthy subjects and would benefit from a fructose diet but also from the fructans which contain some fructose. The intolerance in the fructose is diagnosed thanks to a respiratory test after absorption of fructose. However, the eviction of the fructose is sometimes recommended to the patients without having realized beforehand the test of intolerance.
Ministry of Health and Welfare Department of Chinese Medicine and pharmacy specially subsidizes domestic teaching hospitals to install clinical study centers for Chinese pharmacies, in order to establish the clinical study environment for Chinese pharmacies meeting the international regulations, to assist promoting and performing clinical studies in Chinese pharmacies, and then to improve the nation's health and benefits. This will render Chinese pharmacies competitive in the international market by employing scientific tests and verifications. The new project applications are respectively as follows: A randomized double blind placebo control study of Xiang-Sha-Liu-Jun-Zi-Tang (XSLJZT) in patients with irritable bowel syndrome The main clinical manifestations of irritable bowel syndrome (IBS) are chronic, recurrent abdominal pain or abdominal dyscomfortable associated with the changes of defecation habit, such as constipation and/or diarrhea. Clinical treatment of IBS includes behavioral, and drug treatment, such as anti-diarrheal agent, 5-HT3 receptor antagonist and 5-HT4 receptor agonist, but these treatments relieve partial symptoms only. Xiang-Sha-Liu-Jun-Zi-Tang (XSLJZT) origins from Yizongjinjion, and that uses XSLJZT to treat the patients who has qi deficiency, phlegm-retained fluid, nausea and vomiting, gastrointestinal dysharmony and producing many symptoms. These symptoms of mentioned-above are similar to IBS. Therefore, the purpose of the present study was to investigate the therapeutic effect of XSLJZT on IBS, the investigators designed a randomized double blind placebo control study to assess the effect of XSLJZT on IBS.
Rectal biopsies from IBS patients or healthy subjects will be taken. Biopsies will be used for: 1. the isolation of submucosal plexus to perform: 1.1 live nerve recordings and Calcium imaging; 1.2 immunohistochemistry; 1.3 mRNA (Messenger ribonucleic acids) isolation and real time PCR (Polymerase chain reaction); 2. culturing biopsies On the basis of these observations, the general aim of the study is to move a significant step forward in the current knowledge on human ENS (enteric nervous system) in IBS by establishing a live imaging method to record enteric nerves activity in small intestinal biopsies from humans. This development is unique in its kind as not other research groups have reported successful live recordings with calcium imaging in this preparation. In particular, the investigators aim: 1. to develop and validate the technique to measure activity in human enteric nerves in the submucous plexus isolated from rectal biopsies from healthy subjects and IBS patients; 2. to characterize this nerve activity in healthy subjects and IBS patients using both calcium imaging to evaluate the effect of different neuromodulators, immunohistochemistry and rtPCR to determine receptor expression levels and identify neurons and glial cells in the submucous ganglia; 3. to investigate whether the biopsies of IBS patients secrete more modulators/cytokines compared to healthy subjects and their potential to activate neurons. 4. to evaluate the influence of different food constituents (cow"s milk, wheat, yeast, gluten and soy) on the local reaction of the rectal mucosa and evaluate mast cell activation/degranulation in biopsies of IBS patients compared to healthy subjects. 5. To evaluate the amount of inflammatory mediators/metabolites in urine samples of IBS patients and healthy volunteers by the use of metabolic profiling
This study is a withdrawal randomized clinical trail to evaluate the clinical efficacy and safety of 1.1 chemical drugs N-acetyl glucosamine on Chinese IBS-D patients coming from four centers in chongqing. 180 IBS-D patients in this research are accord with the Rome III diagnostic criteria, screening/import period pain intensity scores of the NRS week mean value are 3.0 plus and the days which at least more than one time a stool type are 6 or 7 type over 2 days/week. Test cycle includes screening/import period (2 weeks), open treatment period (8 weeks), a double-blind placebo-controlled randomized withdrawal period (8 weeks), the main outcome measures are pain intensity (NRS score 11 point scale) and stool type ( Bristol type). And secondary endpoints included overall symptoms sensory scores, defecation frequency, abdominal distension, mucous stool and quality of life parameters (IBS-36 scale). After the end of the treatment period, the participants whose pain intensity and stool type are effective subjects into a randomized withdrawal period, analysis and comparison of the difference between treatment group and placebo group withdrawal rate and curative effect index score reduces.
This study objective is to assess the short and long term effects of partially hydrolyzed guar gum (PHGG) administration on clinical symptoms of IBS and quality of life of these patients.
The investigators will evaluate the efficacy of multi-strain probiotics in adults with diarrhea predominant irritable bowel syndrome.
The study aims to: 1. Determine whether the density of epithelial gaps in terminal ileum of patients with irritable bowel syndrome (IBS) is different from that in inflammatory bowel disease (IBD) patients and normal controls by confocal laser endomicroscopy (CLE). 2. Evaluate the relationship between the density of epithelial gaps and IBS subtypes, and visceral hypersensitivity.
The purpose of this study was to compare the Efficacy and Safety of Tiropramide HCl and Octylonium bromide in the Treatment of Irritable Bowel Syndrome.
