37 Clinical Trials for Various Conditions
This study was a prospective randomized clinical study. There was interventional treatment for a total of 8 weeks including a 2-week washout period. The subjects attended four appointments in the clinic throughout the duration of the study. Study Primary Objective: • To assess improvement in bloating symptoms Study Secondary Objectives: * To assess safety and tolerability of the formulation * To compare the time taken for perceptual improvement in bloating/distention * Enzyme blood assays * To assess quality of life indices
The researchers are trying to find out more about Gastric Antral Vascular Ectasia (GAVE). This is a condition that affects the blood vessels in the stomach, leading to their enlargement and possible bleeding. It can also cause symptoms such as abdominal pain and nausea. By participating in this study, you will help us learn how often these symptoms occur and how they relate to stomach functioning.
The goal of this observational study is to learn about gastric myoelectric activity in children with GI symptoms. The main question it aims to answer is which patterns or signals are associated with GI symptoms as measured by a body surface gastric mapping (BSGM) device. Participants will have their stomach activity recorded for up to 4 hours using the BSGM device and log real-time symptoms. Researchers will compare the recordings of healthy children and children with GI symptoms to define abnormal GI patterns.
To prescribe oral domperidone for patients with upper GI symptoms who have failed or suffered adverse effects from standard medical therapy.
This study's primary aim is to explore the potential differences in the gut mycobiome of children with autism spectrum disorder compared to otherwise healthy children. The secondary objective of this study is to evaluate whether the presence of specific species of fungi (e.g. Candida tropicalis, C. albicans, or Saccharomyces cerevisiae), in stool: 1) correlates with increased gastrointestinal symptoms; 2) correlates with evidence of increased behavioral problems (as assessed by the Aberrant Behavior Checklist or Social Responsiveness Scale-2); or 3) plays the same role as a constituent of commensal gut microflora as in normal controls. The scale indicates severity of social deficits in the autism spectrum as mild, moderate or severe. Additionally, the study aims to compare the fecal and oral fungi in these children because many fecal mycobiota are felt to originate in the oropharynx.
This study evaluates the effects of combination probiotic, prebiotic, and enzyme supplementation on the colonic microbiome of individuals with GI symptoms (e.g. diarrhea, constipation, increased gas). Half of the participants will receive the placebo while the other half will receive the supplement for 28 days.
The goal of this clinical research study is to learn if probiotics found in yogurt can help to decrease gastrointestinal (GI) symptoms in cancer patients. Probiotics are live bacteria and yeast that help with many of our functions and may help digestive problems. Researchers also want to learn if the bacteria in your stool change as your symptoms change while eating yogurt.
The clinical manifestation of autism spectrum disorder (ASD) is complex, with medical and mental health disruptions that occur with the three core behavioral criteria used for diagnosis (social behavior, communication, restricted interests/repetitive behavior). Co-occurring medical conditions, such as gastrointestinal dysfunction (GID), often are overlooked when designing research strategies to understand the mechanisms underlying the expression of ASD. This study was initially a collaboration between Children's Hospital Los Angeles (CHLA) and the Children's Hospital at Vanderbilt University. The current research project proposes to recruit subject at CHLA and the Center for Autism and Developmental Disorders (CAND), a Children's Hospital of Orange County and University of California Irvine (UCI) Health collaborative program. In Aim 1, the investigators will characterize GID in pediatric populations with ASD. Over a 12 month period, subjects will receive standard of care for their GID, typically functional constipation. The study population will be characterized with a standardized instrument for diagnosing functional GI disorders in children, the Questionnaire on Pediatric Gastrointestinal Symptoms, and with the clinical acumen of an experienced pediatric gastroenterologist. Nutritional information also will be collected to determine whether there are patterns of GIDs that correlate with dietary and nutritional status. The in-depth characterization and treatment of GIDs in children with ASD will provide a unique way of determining if ASD symptom and GID symptom improvement are related to each other. In Aim 2, the investigators will do in-depth assessment of each subjects functional status for social communication, emotional regulation, cognitive function, speech-language, sensory integration, and a biomarker of oxidative stress. The latter will be measured in urine samples over the course of one year. There are no direct interventions for autism symptoms in this study. Rather, subjects will receive standard of care for the GID diagnosis and secondary effects on ASD symptoms will be evaluated. Our power calculation shows that the investigators will be adequately powered with the proposed study design and recruitment targets. As part of the study, the investigators have developed a collaboration with investigators in the University of Southern California (USC) School of Engineering, in which the investigators will work with them to develop computational tools to assist in the characterization of videotaped Autism Diagnostic Observation Schedule (ADOS-2) assessments.
Single site, open label, randomized design in patients with relapsing forms of Multiple Sclerosis. At the Screening Visit, the patient will be given a diary containing the MAGIS scale to be completed once a day for the first two weeks while on Dimethyl Fumarate (DMF), including the titration period. After two weeks or if a patient experiences 3 or more consecutive days of GI symptoms in any category of ≥3.5, the patient will return for a Baseline Visit. The MAGIS diary will be reviewed by the coordinator. Any patient who has reported an average MAGIS score of greater than or equal to 3.5 in at least one of the key categories will be randomized to a standard therapy or treatment arm. Patients who report a MAGIS of less than 3.5 during this period will be terminated from the study at this visit. Patients with an average reported MAGIS of greater than 6.5 at Baseline will be placed in the treatment arm. Patients who are randomized to the treatment arm will be instructed to take 125 mg simethicone and one tablespoon of a high fat food (peanut butter) 10 minutes prior to each DMF dose. If the average MAGIS score is greater than 3.5 in the diarrhea category they will also be instructed to take 2 mg loperamide three times daily. Patients randomized to the standard therapy arm will be instructed to follow the normal dosing regimen for DMF with a food bolus of their choice prior to dosing. If severe symptoms (MAGIS \>6.5) are noted at any time post randomization in any MAGIS category, crossover to the treatment arm will be allowed. Both groups will be asked to rate their GI symptoms over the past 24 hours using the MAGIS scale once daily. Both treatment arms will be observed for 6 weeks. MAGIS will be recorded once daily. Patients will return to the clinic at Week 3 and Week 6/End of Treatment for diary and compliance review. After Week 6, patients will be instructed to return to a standard therapy. MAGIS will be recorded for one more week and collected at Week 7/End of Study.
Exendin-(9,39) has been shown to have effects on beta-cell function, and after gastric bypass, to accelerate gastrointestinal transit. - infused at rates of 300pmol/kg/min. Given that gastrointestinal transit is typically delayed by Glucagon-Like Peptide-1 (GLP-1) and also that this hormone causes decreased food intake through increased satiation, it is reasonable to expect an effect of Exendin-9,39 on appetite. This may help explain the effects of gastric bypass on food intake. To examine the effect of Exendin on food intake we propose a dose-response study to determine whether the compound has effects in a dose-dependent fashion. We will examine the presence of gastrointestinal symptoms as well as food intake in the immediate aftermath of a test meal and the subsequent hours.
Use of an oral topically-active glucocorticoid with limited side effects may control the gastrointestinal inflammatory process of GVHD and minimize glucocorticoid exposure.
Hypothesis: * Daily consumption of yogurt containing probiotic bacteria (Bb12) and inulin will significantly decrease whole gut and intestinal segmental transit time * The effect of accelerating intestinal transit will be associated with other GI physiology parameters including stool frequency and stool consistency.

The aims of the study are to investigate individual, combined and added effects of acupuncture and the relaxation response in reducing gastrointestinal symptoms, improving medication adherence and quality of life among people living with HIV/AIDS. The study will also explore the mechanism of these therapeutic effects of acupuncture and the relaxation response.
The purpose of this research is to evaluate if hypnotherapy delivered digitally will help your GI symptoms.
Commercial probiotics can be delivered in numerous forms. The two most common delivery forms are similar to the two product formats to be tested. It has been demonstrated using in vitro testing that probiotic organisms that are unprotected from gastric exposure may not survive that exposure and therefore may not remain viable throughout the rest of the GIT. (Unpublished studies conducted at SNA research facility, February, 2010.) Similar in vitro testing of Acidophilus Pearls has demonstrated the probiotic organisms in an enteric capsule will survive gastric exposure. It is anticipated that this difference in in vitro gastric survivability will translate to improved digestive tract survivability that can be demonstrated using fecal recovery techniques. The commercial product to be tested in this clinical trial has been in the market for over 17 years. However, it is not known what effect this commercial product has on the commensal probiotic population in the gut and particularly in the lower bowel where much of probiotic benefits are believed to be largely realized. Also, it is not known what effect the commercial product has on the total commensal microbiota or fecal pH. While commercial probiotic products have been largely aimed at benefits related to improved health, they also have the potential to change overall gut microbiota (probiotics as well as all others) composition and activities. Learning what happens to the overall gut microbiota can be a helpful step in establishing the potential health benefits of the probiotic class of organisms in the test products.
