Filter by:The daily requirement of threonine, an essential amino acid, will be evaluated in healthy adult males and in adult males with Crohn's Disease or ulcerative colitis using the indicator amino acid oxidation (IAAO) method. Participants will consume specially formulated diets with varying levels of threonine.
Aim: More insight in pathogenesis of IBS and IBD. Samples are collected in context of an European research project.
The immunogenicity of anti-tumor necrosis factor alpha (anti-TNF) therapy in inflammatory bowel disease (IBD) is an important cause of loss of response to therapy that may lead to escalation of dose or discontinuation of therapy. Antibodies may develop to infliximab (ATI) or to adalimumab (ATA) and cause this loss of response, also known as a secondary loss of response. An alternative approach is the addition of immunomodulator (IM) therapy to counteract the antibody response and regain efficacy of the biologic medication. The investigators' goal is to treat patients' who have lost response to adalimumab or infliximab with an immunomodulator with the goal of eliminating the circulating antibodies to the anti-TNF and restoring efficacy.
This is an open-label, phase IV trial. Adult patients, with moderately to severe, steroid dependent, acute ulcerative colitis not previously exposed to anti-TNF, will receive subcutaneous golimumab treatment, according to EU marketing authorization from baseline through week 14. At week 16, patients achieving clinical and endoscopic remission will continue with Golimumab, 50 mg or 100 mg (depending on body weight) every 4 weeks, through week 52. Patients not achieving clinical and endoscopic remission will be treated with infliximab, according to marketing authorization, and followed through week 52. This is not considered as an interventional arm but, since infliximab in Italy is considered as the first-line treatment for UC patients, as the usual clinical practice.
The purpose of this study is to evaluate the efficacy and safety of ustekinumab as intravenous (IV: into the vein) infusion in induction study in participants with moderately to severely active Ulcerative Colitis (UC) and as subcutaneous (SC) administration in maintenance study in participants with moderately to severely active Ulcerative Colitis (UC) who have demonstrated a clinical response to Induction treatment with IV ustekinumab.
Mucosal immunology during helminth infection
The purpose of this study is to evaluate the effectiveness of Fecal Microbiota Transplant (FMT) for treating patients with mild to moderate Ulcerative Colitis (UC). Even with the expanding choices of medication for UC, physicians and patients are still in search of highly effective and safe medications with minimal side effects. FMT has been approved for the treatment of a bacterial infection called Clostridium difficile. In this setting, FMT has been proven to be an effective and safe alternative therapy with zero reported serious adverse events from patients that have had this treatment. The providers that are conducting this study hypothesize that delivering microbes from a healthy human gut can help treat the damages caused by UC. This is done by "transplanting" fecal material, which contains a highly complex and dense community of healthy microbes, including bacteria, fungi and viruses. This collection of microbes is referred to as a microbiome. Preliminary studies suggest that alteration of the microbiome can help treat UC.
This study aims to investigate the role of non-genetic factors in the pathogenesis of inflammatory bowel disease.An exploratory study to investigate differences between the epigenome, microbiota and functional immunology in twins discordant for inflammatory bowel disease.
The anticipated advantages of 3D laparoscopic visualization for the surgeon are greater accuracy and speed in manual skills, translating to decreased operative time, reduced learning curve, and superior safety.We aimed to determine the feasibility of the laparoscopic approach using 3D visualization in the surgical treatment of ulcerative colitis
This national, observational and multicentre study aims at establishing a picture of real clinical practices management among patients treated with Pentasa®, according to the current therapeutic strategy in proctitis or distal proctosigmoiditis. This study should be able to provide data on patients' health related quality of life, compliance and efficacy in real clinical practice
