Filter by:The overall goal of the study is to investigate the dietary differences between children with well-controlled inflammatory bowel disease (IBD) and those with active disease by using targeted food metabolomics. The utilization of the application of targeted metabolomics allows for the investigation of specific components of foods and their effects in IBD and inflammation, which may inform future dietary recommendations for IBD patients.
In order to seek a more precise and convenient treatment, we made a self-made precise transplant capsule that is effective against diarrhea. Compared with standardized fecal microbiota transplantation transplantation on the treat of diarrhea-type irritable bowel syndrome. To observe the similarities and differences of the effect between the two treatment methods on the disease. and the changes in intestinal bacteria was also observed.
The aim of this project is to investigate the implementation of the Rome criteria in daily primary care clinical practice and adherence of general practitioners (GPs) to recommended diagnostic approaches for IBS.
Evaluating any possible relationship between irritable bowel syndrome occurrence and Helicobacter pylori infection
Significant changes in gut microbiota was noted after the high-volume bowel preparation with PEG before colonoscopy. The dynamic changes were found to be short-term. However, the perturbation pattern of gut microbiota found after bowel preparation may link to metabolic syndrome and obesity. No study had investigated the supplementation of probiotic in this dynamic situation before. Here we proposed this study to fulfill the knowledge gap and also inquiry on the potential therapeutic strategy.1.To test the hypothesis of probiotic supplementation after bowel preparation alters the composition of gut microbiota in a short-term and long-term manner.2.To test the hypothesis of GI tract associated symptoms affected by probiotic supplementation after bowel preparation. 3. To test the hypothesis of clinical events, especially parameters of metabolic syndrome affected by probiotic supplementation after bowel preparation.
Irritable Bowel Syndrome (IBS) is a common functional gastrointestinal (GI) condition which is strongly associated with dietary and psychosocial factors. Management of IBS remains challenging for primary health care. The aim is to perform a comprehensive phenotyping of patients with IBS within the primary health care in Region Örebro County, Sweden. Following this phenotyping, the investigators will perform a prospective randomized controlled trial of two different treatments versus control as described below. Subsequently, the investigators want to evaluate the result of the treatments in order to see whether the presence of a certain phenotype can predict the efficacy of different treatments. Our hypothesis is that the presence of certain baseline symptom characteristics in patients with IBS can predict how effective internet based cognitive behavioral therapy (iCBT) and low FODMAP (low Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) treatment will be for each patient. 200 patients with IBS aged 18-65 years will be recruited from the primary health care in Region Örebro County. The study plan is structured as follows: 1. Phenotyping of IBS patients. Investigation of the correlation between different psychological parameters, IBS symptom severity and Quality of Life. 2. The effect and outcome of 10-weeks internet-based cognitive behavioral therapy (iCBT) versus control in IBS patients. 3. The effect and outcome of 10-weeks low FODMAP diet versus control in IBS patients. 4. Comparison of iCBT and low FODMAP treatment in IBS patients and identification of baseline phenotypic characteristics predicting treatment outcome for both treatments. Stool and blood samples will be taken before and after treatment for analysis of gut microbiota, proteomics and epigenetics and to correlate these with the clinical phenotype. All participants will undergo phenotyping regarding GI symptoms and psychological variables using questionnaires. Participants will afterwards be randomised to either 10 weeks treatment with iCBT (80 participants), low FODMAP (80 participants) or control group (40 participants) (2:2:1 randomization). The control group will wait 10 weeks before being randomised to either iCBT (20 participants) or low FODMAP (20 participants). Significance This study will provide effective and individualized treatment for IBS patients. This may lead to the development of a guideline to improve the effectiveness of treatment and care for patients with IBS.
assess the incidence of the entire spectrum of esophageal disorders and possible theories for overlap in IBS patients using different diagnostic modalities.
This study aims to compare visceral rectal sensitivity and quality of life of 40 Irritable Bowel Syndrome women, with (20) and without sexual dysfunction (20). Both Irritable Bowel Syndrome (IBS) and sexual dysfunction (SD), decrease quality of life (QOL) separately, and only recently we have shown that quality of life decreases even more with both diseases. Thus, there is clinical evidence to search for a biological marker that explains this cumulative effect. Investigators will determine IBS using the Rome IV criteria, SD through the Female Sexual Function Index (FSFI) while and QOL through the Short Form-36 and the IBS-QOL. Visceral sensitivity will be evaluated by a barostat study: A small bag connected to a computer is placed in the rectum. This computer will insufflate air increasing the volume and simultaneously record the pressure inside the rectum; therefore investigators can simulate what happens when the stool reaches the rectum. The patient reports the first sensation, gas sensation, need to defecate and even pain. For patient protection the pressure will never exceed 50 mmHg and/or if any amount of pain is reported. To assess the effect of food on this visceral sensitivity, it is performed in 2 stages, fasting and 30 minutes after a standardized meal. The protocol will be carried out through 3 visits. First patients will be recruited; the diagnosis of IBS, SD, quality of life will be established and basic laboratory tests will be schedule before next visit. Second visit will be on day 7 of the menstrual cycle when investigators will carry out the barostat study and determination of blood´s sex hormones. The last visit is for the second barostat study on day 21 of the menstrual cycle with sex hormones measurement. This protocol will compare: Rectal pressure and volume for tone, first sensation, gas sensation, desire to defecate and pain, measure during fasting and postprandial periods in day 7 and 21 (estrogenic and progesterone phase) of the menstrual cycle. Other variables include (age, marital status, disease history, SF-36, IBS-QOL, etc.). This study aims to find a biological marker to explain the low QOL observed in daily clinical practice. This approach will allow us a more effective diagnosis and perhaps the creation of more effective therapeutic approaches to treat these patients. In the long term, we expect to establish the foundations of a patient-centered medicine with shared decision more effective in the gut brain axis disorders.
The primary objective is to compare the effectiveness of the experimental Intermittent Colonic Exoperistalsis (ICE) treatment with MOWOOT, with the active control of trans-anal irrigation (TAI) as standard-of-care. The secondary objectives are to further compare the ICE treatment with MOWOOT to the TAI standard-of-care clinically and economically.
Irritable bowel syndrome is a functional disorder of the gastrointestinal tract diagnosed with the Rome criteria. The Rome IV criteria are based on abdominal pain symptoms and stool habits including stool frequency and stool forms [1]. They define 3 main subtypes based on symptoms: 1) IBS with diarrhea; 2) IBS with constipation: and 3) mixed symptoms of constipation and diarrhea. The IBS with diarrhea (IBS-D) subtype has the highest prevalence. Currently, treatment of IBS-D includes antidiarrheals, bile acid sequestrants, antispasmodics, tricyclic antidepressants, and FODMAP diet. However, many patients are intolerant or unresponsive to the above treatments. Outside of IBS, chronic diarrhea affects about 5% of adults. We have described a syndrome in a subset of IBS patients presenting with post prandial diarrhea, flushing and dermatographia whose symptoms are prevented by pre-treatment with combined H1 and H2 antihistamines [2]. However, the prevalence of this syndrome among the IBS + D patients is not known nor have the clinical characteristics or predictors of antihistamine responsive IBS + D been defined.
