Filter by:To determine whether a lacto-ovo vegetarian diet is effective in improving gastrointestinal symptoms, quality-of-life, intestinal inflammation and gut microbiota composition in mild-to-moderate IBD compared to a standard omnivorous diet.
This is an interventional randomized ope-label two-arm trial on the peri-operative use of immunonutrition in Crohn's Disease (CD) patients undergoing colorectal elective surgery.The aim of the trial is to assess the effectiveness of immunonutrition therapy in decreasing the rate of post-operative infective complications and 6 months endoscopic disease recurrence.
The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.

Search for mechanisms of the effect of fecal transplantation on a healthy organism and various nosological forms.
Autologous ADSVF constitutes an innovative therapeutic strategy that concentrates various types of regenerative stem cells and paracrine factors able to promote angiogenesis and tissue repair. Together with the ease of collection from a minimally manipulated lipoaspirate, the unique properties of ADSVF offer new opportunities for fistulas' healing in patients with CD. The use of ADSVF is currently developed in many clinical fields based on safety and efficacy data. Our ADICROHN pilot study evaluating safety and tolerance of local administration of autologous ADSVF with microfat in CD patients with complex perianal fistula refractory to conventional medical and surgical therapy showed that this novel therapeutic approach appears feasible and safe. However the therapeutic potential of local this combined treatment in healing refractory perianal Crohn's fistulas still remains to be demonstrated. The main objective of this study is to assess the efficacy of local injection of autologous ADSVF and microfat versus placebo for the treatment of complex refractory perianal Crohn's fistulas at week 24. The efficacy will be assessed on clinical assessment of closure of all the external openings that were drained at baseline, and MRI confirmation of absence of collections > 2 cm of the treated perianal fistulas at week 24.
The purpose of this survey is to evaluate the long-term safety and effectiveness of vedolizumab for intravenous (IV) infusion 300 milligrams (mg) in Crohn's disease (CD) patients in the routine clinical setting.
The purpose of this study is to determine if vitamin D as an adjuvant therapy can improve the outcome (i.e. fewer relapses) and the quality of life, including levels of physical activity, in children diagnosed Crohn's disease (CD).
Inflammatory bowel disease (IBD) is a term that defines a chronic disease characterized by inflammation of the intestine. It includes ulcerative colitis (UC) and Crohn's disease (CD). The objective of the study was to administer a treatment based on a group adaptation of the BMGIM in patients with inflammatory bowel disease (IBD) and assess its impact on state of mind, quality of life, anxiety, depression, immunocompetence as a marker of well-being, and levels of acute and chronic stress. To achieve the objectives a quasi-experimental, quantitative, qualitative, analytical, and prospective study was performed. 41 patients with IBD divided into a test group (24 patients), who received 8 sessions over 8 weeks, and a control group (17 patients). A saliva sample was taken from each patient before and after each session to determine cortisol levels (acute stress) and IgA (immunocompetence) using ELISA. A series of questionnaires were completed as follows: HADS (perceived anxiety), MOOD (state of mind), and CCVEII (quality of life). Similarly, a hair sample was taken before the first and after the last session to determine the cumulative cortisol level (chronic stress) using ELISA.
Crohn's disease (CD) is a chronic relapsing-remitting systemic inflammatory disease, affecting any part of the gastrointestinal tract. Biological therapy with anti-tumor necrosis factor (TNF) alpha is the established treatment of choice for the management of moderate to severe Crohn's disease. However, its efficacy in an individual patient is the unpredictable and long-term outcome is still suboptimal. Identifying biomarkers which can predict treatment response is thus of utmost importance and can allow personalized management. In inflammatory bowel disease (IBD), altered fecal microbiota signatures have been consistently reported. Moreover, overall bacterial diversity is consistently decreased during intestinal inflammation. Fecal calprotectin (FC) is a calcium and zinc binding protein largely confined to the neutrophil granulocytes and macrophages and is a very sensitive marker for detection of inflammation in the gastrointestinal tract. C reactive protein (CRP) is an acute phase reactant. CD Patients with elevated baseline CRP levels responded to infliximab treatment better and early normalisation of CRP correlated with sustained long-term response to infliximab therapy. The investigators hypothesize that faecal microbial signatures in conjunction with faecal calprotectin and CRP may have a role in predicting response to biological therapy in CD patients.
