Active clinical trials for "Irritable Bowel Syndrome"

This is a multicenter cross-sectional study on the prevalence of Irritable Bowel Syndrome and the risk factors associated with it. The Rome IV criteria is used for diagnosing IBS. A questionnaire-guided interview will be applied to all subjects.

Background: The incidence of postinfectious irritable bowel syndrome (PI-IBS) was reported to be in the range of 5-30%, but limited number of long-term follow-up results. Objective: To investigate the long term clinical course of PI-IBS after Shigellosis. Setting: A Shigellosis outbreak in a tertiary referral hospital with about 2,000 employees in Korea at 2001. Patients: A Shigella-exposed cohort of 124 hospital employees who had been infected by Shigella sonnei due to contaminated food in the employee-cafeteria in Gangnam Severance Hospital, Seoul, Korea, at December 2001. A control cohort of age and sex-matched, non-infected 105 contemporary hospital employees. Measurements: Questionnaire survey for bowel symptoms at 1, 3, 5, 8 and 10 years after outbreak.

Objective: To confirm the psychometrics properties of the Intestinal Gas Questionnaire (IGQ) in subjects with Irritable Bowel Syndrome (IBS) diagnosis and General population both complaining of Gas-Related Symptoms (GRS). IGQ has been developed previously simultaneously in UK English, French and Spanish through qualitative research with subject interviews. The conceptual framework of the IGQ assesses both GRS and their impact on daily life. Similar concepts were identified for both subjects with IBS diagnosis and general population and complaining of gas-related symptoms. The IGQ consists of a 24-hour recall symptom diary assessing 7 gas-related symptoms (17 items) and a 7-day recall questionnaire which assesses the impact of those symptoms (26 items)

This is a retrospective study designed to gather outcomes data from existing medical charts from patients who have taken EnteraGam for management of their IBS-D for at least eight weeks. Data from two study periods will be collected: (1) the time during which the Standard of Care (SOC) therapy (i.e., prescribed or over-the-counter as well as FDA-approved or non-approved agents) that is used immediately prior to prescribing EnteraGam; and (2) the time during which EnteraGam is used as therapy.

The primary objective is to obtain stool samples from subjects diagnosed with , and displaying signs and/or symptoms of IBD and/or IBS will be evaluated in this study. Eligible subjects require a diagnostic colonoscopy with possible biopsy and clinical evaluation.

The investigators will conduct a cross-sectional study to discovery the distribution of IBS subtypes who would like to seek TCM treatment and their TCM patterns. At the same time, the investigators will also collect the serum, urine and stool samples of the participants to explore the host-gut microbiota metabolic interactions associated with IBS subtypes.

Observational Prospective Study to Describe Irritable Bowel Syndrome in the Russian Federation

This is a prospective, clinical, multicentre study aimed to collect biological samples and study microbiota from subjects with Clostridium Difficile (CDI), subjects affected by Multi Drug Resistant Organisms (MDRO) infection, subjects with Chronic Inflammatory Bowel Disease (IBD), subjects with Irritable Bowel Syndrome (IBS), subjects with Hepatic Encephalopathy and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological) The study will allow to: Provide biological samples (faeces, saliva, blood, urine) from healthy volunteers and patients to the first Italian microbiota biobank; Study microorganisms using different in vitro and in vivo techniques; Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.

A study to evaluate, by country and overall, the changes from baseline of the irritable bowel syndrome quality of life (IBS QoL) total score after 4 and 8 weeks of treatment with Duspatalin® or Dicetel® in IBS patients.

The prevalence of IBS in the community has been reported in numerous cross-sectional surveys. However, less is known about the incidence of IBS ,mainly due to its slow development and to patients under-reporting. Furthermore, only one study has analyzed data concerning potential risk factors for the diagnosis of IBS. The investigators will examine the incidence of IBS in a large cohort of young adults and will look at the association of socioeconomic, anthropometric and occupational factors with IBS incidence.
