View clinical trials related to Irritable Bowel Syndrome.
Filter by:Irritable Bowel Syndrome (IBS) is a disease associated with changes in bowel habits characterized by unexplained abdominal discomfort or pain. Common symptoms of the disease include gas, bloating, diarrhea, constipation, and common gastrointestinal problems associated with psychosocial problems. IBS makes it difficult for patients to attend school and work, reduce productivity, increase healthcare costs and negatively affect quality of life. Although IBS is not a life-threatening disease, it is a condition that must be tackled throughout life. The disease is clinically managed through dietary interventions and appropriate lifestyle changes, and pharmacological symptom-targeted or psychological treatments. The aim of this study is to determine the effects of different dietary treatment methods on patients 'severity symptom score and quality of life, and the patients' compliance with different dietary treatments.
A cross-sectional study was conducted to collect the relevant data of college students' mobile phone addiction and FGIDs (IBS, FD) in the form of questionnaire, so as to understand the situation of college students' mobile phone addiction and the incidence of FGIDs (IBS and FD), and explore the correlation, so as to provide new ideas and scientific basis for the prevention, diagnosis and treatment of FGIDs among college students.
The purpose of this study is to investigate if the probiotic Bifidobacterium breve Bif195 (Bif195) will result in improvement in clinical outcome in patients with diarrhea-predominant irritable bowel syndrome (IBS).
Rationale: Irritable Bowel Syndrome (IBS) is a disease that affects a large number of people. To date, no adequate treatment is available. This is partially due to the heterogeneity of the patients and the complicated pathology in which not all mechanisms are understood. Based on results of in vitro screening within the IBSQUtrition project, we selected promising dietary supplements for validation of their potential beneficial effects on stool pattern in IBS-Constipation (IBS-C) patients. Objective: The primary objective is to determine the effects of a 4-week intervention with either a prebiotic supplement or a probiotic supplement on stool pattern (including stool frequency, consistency, and volume) in IBS-C patients. The secondary objective is to determine the effects if this intervention on GI complaints and quality of life in IBS-C patients. Study design: A double-blind, randomized, placebo-controlled trial will be conducted with three parallel intervention arms Study population: 180 adult (18-70 yrs) IBS patients with a constipation-predominant subtype Intervention: A 4 week run-in period will be followed by a 4-week intervention period with three parallel arms: 1) prebiotic supplement, 2) probiotic supplement, and 3) Placebo supplement, during which the study participants consume the respective supplement twice per day. Main study parameters/endpoints: The primary study parameter is stool pattern: stool frequency, stool consistency; and stool volume. The secondary study parameters are gastrointestinal complaints, Quality of Life, and HADS. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Study participants have to invest about 14.5 hours of their time in this study mainly to complete several questionnaires (short daily questionnaire, longer questionnaires at three occasions), which is conveniently all possible from home. They have to comply to consume a supplement twice daily for four weeks. At two time points they have to collect their stool for five consecutive days. There are limited risks for the study participants.
Rationale: Irritable Bowel Syndrome (IBS) is functional gastrointestinal disorder that affects a large number of people. To date, no adequate treatment is available. This is partially due to the heterogeneity of the patients and the complicated pathology in which not all mechanisms are understood. Based on results of in vitro screening within the IBSQUtrition project, we selected promising dietary supplements for validation of their potential beneficial effects on the microbiota of IBS patients. Objective: The primary objective is to determine the bifidogenic effects of a 4-week intervention with one of four dietary supplements (Chondroitin sulfate, NOVELOSE® 3490, and Pea Fiber, and Lactium®) in IBS patients. The secondary objective is to determine the effects of the same intervention on fecal microbiota composition and SCFA concentration, IBS-related complaints, Quality of Life, and stool frequency and consistency in IBS patients. Study design: a double-blind, randomized, placebo-controlled trial with five parallel arms. Study population: 70 adult (18-65 yrs) IBS patients Intervention: 4-week intervention period with five parallel arms: 1) Chondroitin sulfate, 2) NOVELOSE® 3490, 3) Pea Fiber, 4) Lactium®, and 5) Placebo supplement (Maltodextrin control), during which the study participants consume the respective supplement twice per day. Main study parameters/endpoints: The main study parameter is the (relative) abundance of fecal Bifidobacterium. The secondary study parameters are fecal microbiota composition and Short-Chain Fatty Acids (SCFAs) concentration, stool frequency and consistency, IBS-related complaints, and Quality of Life (QoL). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Study participants have to invest about 7.4 hours of their time in this study mainly to complete several questionnaires (short daily questionnaire, longer questionnaires at two occasions), which is conveniently all possible from home. On two occasions they have to collect stool (transported via courier to the research facility). They have to comply to consume a commercially available supplement twice daily for four weeks. There are limited risks for the study participants.
This study was designed as a pilot, open-labelled study. We enrolled consecutive IBS-M patients (n=25, 19 females, 46.06 ± 13.11 years) according to Rome IV criteria. Fecal samples were obtained from all patients twice (pre- and post-intervention) and high-throughput 16S rRNA sequencing was performed. Patients were divided into two groups based on age, gender and microbiome matched. Six weeks of AI-based microbiome diet (n=14) for group 1 and standard IBS diet (Control group, n=11) for group 2 were followed. AI-based diet was designed based on optimizing a personalized nutritional strategy by an algorithm regarding individual gut microbiome features. An algorithm assessing an IBS index score using microbiome composition attempted to design the optimized diets based on modulating microbiome towards the healthy scores. Baseline and post-intervention IBS-SSS (symptom severity scale) scores and fecal microbiome analyses were compared.
The aim of the study is to evaluate the effects of a specific Cognitive Behavioral treatment protocol for patients with IBS used in routine care at a gastroenterology unit in Stockholm. The research question is whether the treatment has the same effects in routine care as it has had in efficacy studies. The treatment is given by licenced psychologists (with CBT training) face-to-face in groups of 4-7 participants and lasts for ten sessions (ten weeks, normally).
Intestinal Bacterial Overgrowth (IBO) is a common functional condition due to excessive amounts of bacteria in the gastrointestinal tract. These bacteria ferment ingested food resulting in the production of hydrogen, methane, and carbon dioxide which subsequently can induce GI symptoms including abdominal pain, bloating, distention, diarrhea and constipation. Typically this condition is treated with antibiotics but for a portion of patients symptoms often recur. Recent work suggests that increased methane production may emanate from overgrowth of a specific type of archaebacteria, causing the aforementioned symptoms. However, no current therapies exist to treat this phenomenon. The investigators propose to trial the supplement Atrantil on patients with IMO in order to study the supplements impact on symptoms, quality of life, and methane levels.
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.
