Filter by:The purpose of this observational study is to assess the safety and effectiveness of biosimilar Infliximab in patients with inflammatory bowel disease (IBD) in Saudi Arabia where no visits or intervention(s) additional to the daily practice will be performed.
Ulcerative colitis (UC) is a chronic inflammatory disorder of the gastrointestinal tract of unknown etiology. UC is characterized by recurring episodes of inflammation limited to mucosal and submucosal layers of the colon. The object of the present study was to determine the prevalence of intestinal protozoa and helminthes in UC patients, and the role of this changes in aetiopathogenesis of diseases. Patients will be examined before and after therapy. Parasites and protozoa prevalence and intensity will be detected by triple coproscopy.Microbiological study will be conducted before therapy for detection pathogenic bacteria only from UC patients infected with B. hominis . If intestinal pathogenic bacteria are found, participants will be excluded from further investigation.
Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) characterized by chronic inflammation limited to colonic mucosa. Its pathogenesis is not still clear, even if a multifactorial aetiology has been advocated. The aim of this study is to evaluate the long-term efficacy of two different doses of VSL#3® added on standard therapy (5-ASA) in maintaining remission in an adult population of patients with UC, compared with the standard therapy (5-ASA) plus placebo. The investigators hypothesized that adding VSL#3® to mesalamine would lead to higher remission rate at long-term evaluation.
The M2iSH laboratory showed with two previous clinical trials that Crohn's Disease (CD) macrophages present i) a defect to control Adherent-Invasive Escherichia coli (AIEC) infection related to polymorphisms associated with CD; ii) a CD - specific cytokine secretion profile after an AIEC infection and intestinal inflammation dependent; iii) a modification of the response of CD macrophages at a basal state and after the AIEC infection. These results consolidate the hypothesis of a defect specific to CD macrophages. That's why, the primary purpose of this study is to realize a proteomic analysis of macrophages of CD patients infected or not with AIEC and to compare them to Ulcerative Colitis (UC) patients and healthy volunteers.
Breastfeeding is beneficial to both mother and baby. However, many breastfeeding women are affected by long-term health conditions and need to take medications. Sometimes, concerns about transfer of drugs to infants via breast milk lead the mothers to either avoid breastfeeding or stop their medication. Inflammatory Bowel Disease (IBD) is a chronic condition that is marked by an abnormal response of the body's immune system, and high levels of certain proteins that cause inflammation (Cytokines like Tumor Necrosis Factor-alpha or TNFα). A group of drugs called "biologics" target and stop these proteins from causing inflammation, and have been successfully used to treat this condition. Inflammatory proteins may be present in breast milk of healthy women in variable levels, and may play a role in development of infant's brain and immune system. This study is being conducted to investigate: - Concentration of some of the inflammatory proteins in breast milk of mothers with IBD and healthy controls - Interaction between these proteins and biologics in breast milk of women with IBD - Potential role of these proteins (and their interaction with biologics) on development of infant learning and memory function It has been presumed that concentrations of TNFα and some other cytokines are higher in breast milk of women with IBD, and the biologics can normalize these high levels. Due to precautions for COVID-19, the study now consists of only two mandatory study visits and two optional study visits. The mandatory visits include two home visits in the first 4 months postpartum to complete a participant questionnaire and collect a small sample of breast milk at each visit. The optional study visits consist of two visits at the Hospital for Sick Children for evaluation of learning and memory function of the infant at the ages of 12 and 18 months. Additionally, mothers will be required to complete for their infant subscales of The Ages and Stages Questionnaires®, Third Edition (ASQ®-3) either in person or over the telephone at the ages of 12 months and 18 months.
TNF inhibitors have improved treatment options for patients with inflammatory bowel disease (IBD) and three TNF inhibitors, infliximab, adalimumab and golimumab are available for treatment of ulcerative colitis in Switzerland. However, these drugs have been tested under ideal conditions in randomized controlled trials. Real-world data are needed to complement this information. It is the aim of our study to test, whether patients with ulcerative colitis can be effectively treated with golimumab in a real world setting in Switzerland. The investigators will use data from the Swiss IBD cohort study (SIBDC) in Switzerland. They will identify all SIBDC patients with UC treated with Golimumab and perform a retrospective chart review. The investigators will acquire patient reported outcomes and objective measures for inflammation at baseline, at 6-10 weeks and at 6 and 12 months after golimumab treatment. Primary endpoint will be clinical response (i.e. meaningful improvement) at 6-10 weeks. Secondary endpoints will be clinical response at 6 and 12 months and clinical remission (i.e. free of symptoms of disease).
The aim of our study is to investigate the efficacy and safety of fecal microbiota transplantation (FMT) in the treatment of antibiotic dependent chronic pouchitis. This is a double-blinded randomized placebo controlled study. 13 patients receive a fecal transplantation from the healthy tested donor and 13 patients in the control group receive their own feces.
This study is an open-label study aiming at evaluating the long-term safety and the efficacy profile of ABX464 given once a day (o.d) at 50 mg in subjects who have been previously enrolled in the ABX464-101 clinical study (induction study) and who are willing to continue their treatment.
Inflammatory Bowel Diseases (IBD) is a heterogeneous group of diseases regarding clinical presentation, disease course and treatment response. Pathogenesis is complex and multifactorial, based on interactions between genetic and environmental factors, gut microbiota and the immune system, leading to intestinal inflammation. As the immune reaction itself causes the intestinal damage, differences in components of this immune mediated inflammatory reaction between IBD patients might explain the heterogeneity in response to different therapy strategies. Identifying immune components that are associated to disease activity and prognosis would enable a more personalized treatment.
Spondyloarthritis and inflammatory bowel diseases are common diseases, frequently met together in overlap syndromes. Their physiopathology remains puzzling. A strong role of gut microbiota has been recently put forward to explain the development of inflammatory bowel diseases, and is suspected to play an important role in rheumatoid diseases. Anti-Tumor Necrosis Factor (anti-TNF) alpha are effective and safe drugs in the treatment of both digestive and rheumatoid inflammatory diseases. The way they work is unclear, and the clinical response to this treatment is variable. A better understanding of the pathophysiology of inflammatory bowel diseases and of the action of anti-TNF alpha is essential to an optimized care. Our hypothesis is that the efficacy of anti-TNF alpha in spondyloarthritis and in inflammatory bowel diseases is at least partly due to its restoring action of homeostasis at the interface between gastrointestinal mucosa and intestinal microbiota, either by primary action on the digestive epithelium, allowing it to regain its control and tolerance functions toward mucosal microbiota, either by direct action on the intestinal microbiota, via an inter-reigns regulation. The main objective of our study is to assess quantitative and qualitative changes in fecal microbiota before (D0) and 3 months after initiation of anti-TNF alpha.
