Filter by:Evaluation of the effects of butyrate ( BitirBioma) and palmitoylethanolamide( PEA=PeaBioma) on intestinal permeability and gut microbiota composition in patients with irritable bowel syndrome. Study B/P 3_1 is an interventional study involving the use of food supplements on the market (BitirBioma Plus and PeaBioma Plus), single-center, double-blind, placebo-controlled, crossover, randomized, in n=50 patients with bowel syndrome irritable, diarrheal and mixed variant (IBS-D and IBS-M), lasting for one year. The study has two arms: Group 1: n=25 Treatment A e Group 2: n=25 Treatment B (with - Treatment A: 3 capsules/day of butyrate (625 mg) + 3 capsules/day PEA (200 mg) at a ratio of dosage of 3/1 - Treatment B: Placebo (3+3/day capsules of starch). Eligible subjects with IBS will be randomized in a 1:1 ratio to treatment A or treatment B for six weeks. After the first treatment period, there is a 14-day washout period. Hence, individuals will be treated with B/A treatment for additional six weeks, according to the crossover design. In the two treatment periods, subjects will be required to complete a visual analogue score VAS questionnaire to assess gastrointestinal symptoms and Stool Bristol Scales. During the visit, the subjects will have to record Questionnaire Rome IV to evaluate their quality of life. At the same time, it will be theirs required to provide: - fecal sample for the evaluation of the composition of fecal microbiota (Biomaplan Kit) - a urine sample for the evaluation of intestinal permeability (Gastropack) a capillary blood sample and a serum sample for the detection of Zonulin (Kit Healthy gut and Immundiagnostik AG ) - a capillary blood sample and a serum sample for the detection of Zonulin (Kit Healthy gut and Immundiagnostik AG )
This study measures effects of water filters and filter types on household health in Ciudad Victoria, Mexico.
The research group intends to carry out a case-control study to recruit IBS-D patients with anxiety and depression symptoms, by collecting intestinal mucosa for single-cell transcriptome sequencing, collecting peripheral blood for proteomic analysis, the two groups and patient symptoms are associated, and then discover the characteristics of molecular level changes associated with brain-gut axis dysfunction, explore the pathophysiological mechanism of comorbid anxiety and depression and IBS, and discover potential targets for effective treatment. This project can help to construct the colonic single-cell map of IBS-D patients and explore the differentially expressed genes in the colon of IBS patients and their signaling pathways related to neuroregulation, providing an effective therapeutic target for the treatment of comorbid anxiety and depression and IBS.
This study will assess the long-term safety of oral Eluxadoline administered to pediatric participants with IBS-D who have completed study intervention in the Phase 2 study 3030-202-002 or the Phase 3 study 3030-303-002.
Crohn's disease is an inflammatory disorder that can affect any part of the gastrointestinal (GI) tract. Some patients still experience persistent diarrhea or other symptoms such as abdominal pain even when their Crohn's disease is in remission. Diarrhea and/or abdominal pain that is not responsive to standard therapies can significantly affect a patient's quality of life and ability to work. The purpose of this study is to test the safety and effectiveness of the drug ranolazine in reducing Crohn's disease-associated diarrhea and other symptoms. Ranolazine is approved by the US Food & Drug Administration (FDA) for chronic angina (a heart condition). This study is investigating if ranolazine could be used in the setting of Crohn's disease.
The purpose of this project is to systematically collect clinical and nutritional outcomes information on patients treated for Shigella infection so that physicians and clinical laboratories can better define which Shigella infections are "resistant" to antibiotics and which are "susceptible", focusing on azithromycin a last-line drug to treat drug resistant Shigella
The study is on indefinite HOLD due to the loss of funding that occurred during the pandemic emergency. Subsequently, a key collaborator left our institution, and as a near-term result, the protocol awaits reactivation. Three patient subjects were enrolled, all 3 patients/subjects were cured of the infection, and there were no adverse events or sequelae observed or reported. The aim of the study continues to confirm and extend the work of Trede and Rask-Madsen (Lancet 1989;1:1156-1160) that administration of a defined fecal microbiota will lead to rapid and sustained resolution of C. difficile-associated chronic relapsing diarrhea. FDA required 4 non-geriatric qualified patients to be studied before including the elderly. However, C. difficile-associated chronic relapsing diarrheal illness is predominantly a disease of the elderly, so this requirement GREATLY impeded timely enrollment. No protocol deviations have occurred. The current rationale behind FMT for CDI is that the introduction of microbes from a healthy donor should allow for the restoration of a normal microbial community in the diseased host with consequent suppression of C. difficile colonization and disease pathogenesis. The first modern use of FMT was reported in a 1958 case series of 4 patients with pseudomembranous enterocolitis. The first case of confirmed CDI treated with FMT was reported in 1983; treatment was curative. Until 1989, retention enemas were the most common technique for FMT. Alternative methods for delivering FMT have included fecal infusion via duodenal tube (1991), rectal tube (1994), and colonoscopy (1998). FMT for recurrent CDI has been used successfully, whether administered by nasogastric tube, rectal administration by colonoscopy, or rectal tube, including self-administration at home by enema. FMT has proven to be remarkably effective and remarkably safe without any significant problems (see below and attached reviews and meta-analyses). Increasing interest is emerging regarding the changes in the intestinal microbiota associated with CDI. In 2008 Chang et al. constructed small (< 200 sequences per subject) 16S rRNA gene libraries from the stools of 4 patients with first-time CDI and 3 patients with recurrent CDI. Based on 16S rRNA gene classification, they found that the fecal microbiomes of patients with an initial episode of CDI were similar at the phylum level to healthy subjects (i.e., the majority of sequences belonged to dominant fecal phyla Bacteroidetes and Firmicutes), while a major reduction or loss of Bacteroidetes was observed in patients with recurrent CDI. The loss of the Bacteroidetes was accompanied by the expansion of other phyla, including Proteobacteria and Verrucomicrobia, which are normally minor constituents of the fecal microbiota. Khoruts et al. (2010) compared the microbiota of a patient with recurrent CDI before and after FMT by using terminal-restriction fragment length polymorphism and clone-based 16S rRNA gene sequencing. Before transplantation, the patient's microbiota was deficient in members of Bacteroides and instead was composed of atypical fecal genera such as Veillonella, Clostridium, Lactobacillus, Streptococcus, and unclassified bacteria similar to Erysipelothrix. Two weeks after the infusion of donor fecal suspension, the bacterial composition of her feces approached normal and was dominated by Bacteroides sp. strains. In 1989, Tvede and Rask-Madsen used a combination of nine normal fecal organisms to treat 6 patients with chronic relapsing C. difficile diarrhea. These investigators cultivated 10 strains of bacteria, including Enterococcus (Streptococcus) faecalis (1108-2), Clostridium inoculum (A27-24), Clostridium ramosum (A3I-3), Bacteroides ovatus (A40-4), Bacteroides vulgatus (A33-14), Bacteroides thetaiotaomicron (A33-12), Escherichia coli (1109), E. coli (1108-1), Clostridium bifermentans (A27-6), and Blautia producta (Peptostreptococcus productus) (1108-2) in broth for 48 h to a concentration of approximately 10 to the 9th power bacteria/mL. Two mL from each bacterial culture were admixed with 180 mL saline that had been pretreated in an anaerobic chamber for 24 h; the bacterial suspension was then instilled rectally. This procedure was followed promptly by a decline of C. difficile to undetectable levels by culture and the loss of detectable toxin from the stools. Normal bowel function was restored within 24 hours, and abdominal symptoms disappeared. Stool cultures and toxin assays for C. difficile remained negative during a year of follow-up. It is especially important to note that feces from none of the 6 patients contained Bacteroides sp.
