Filter by:To evaluate the efficacy and safety of 12-week goal-directed therapy in the treatment of refractory inflammatory patients, and to initially explore treatment options. Patients with potential risk factors for recurrence after surgery for Crohn's disease and a serum 25(OH)D concentration <75 nmol/L were prescribed oral liquid vitamin D supplementation over 12 weeks using a specific protocol with dose adjusted 4-weekly to aim for a target level of 100-125 nmol/L.
Inflammatory bowel disease (IBD) is a common disease in Canada, leading to significant morbidity as a result of remitting and relapsing intestinal inflammation. Currently, tumor necrosis factor (TNF) antagonists such as infliximab, make up 30% of the biologic agents available to individuals with IBD. There is a high risk of losing response or having a hypersensitivity reaction to infliximab, necessitating treatment discontinuation. This is due, in part, to the formation of anti-drug antibodies (ADAs). ADA formation can result in loss of response to therapy which may eliminate an intestine-saving therapy and increases their risk of progressing to surgical resection. There are few tools clinicians can implement to minimize the risk of ADA formation. The current approach is to add a second drug (known as combination therapy), specifically an immunomodulator (methotrexate or azathioprine), exposing the patient to additional medication-related risks, intensive monitoring with bi-weekly blood work and potential side effects including infection and malignancy. Preliminary data from our group as well as others suggests that individuals who carry a variant in the class 2 human leukocyte antigen (HLA) gene (HLADQA1*05A>G, rs2097432) are more likely to form ADAs to infliximab. Pre-emptive screening for this variant may allow clinicians to more selectively use combination therapy, recommending it only in IBD patients at high risk of developing ADAs to infliximab. Additionally, this may result in fewer drug-associated adverse events. With this project, we aim to explore the value of prospective HLADQA1*05 screening (pharmacogenomic screening) in IBD patients being considered for treatment with infliximab and using the result to guide the application of combination therapy compared to IBD patients treated with infliximab (with or without a second agent) as per current practice. We will assess the incidence of infliximab ADA formation, as well as the incidence of infliximab loss of response, treatment discontinuation, and adverse drug events. Additionally, we will assess the time to each of these events.
By capturing possible or known risk factors, it will be possible to recognize connections between these risk factors and the disease, thus obtaining valuable insights into the cause of the disease. This in turn facilitates an improved evaluation of the treatment situation as well as influencing future framework conditions for preventive measures and planning treatments. Disease registries are thus crucial for the planning and structuring of health policies. The present registry protocol serves as a basis for the proper implementation of a registry for patients with chronic inflammatory bowel diseases. It describes the study rationale, objectives, design, participant groups, procedures and evaluation methods. Furthermore, it defines the responsibilities of each person involved in maintaining the registry and also forms the basis for decisions regarding evaluation by the Ethics Committee.
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.
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 goal of the study is to assess the impact of treatment with dietary supplement containing Saccharomyces boulardii (used as an addition to standard therapy), on quality of life of patients with mild forms of ulcerative colitis and Crohn disease, as well as those in remission fulfilling criteria for irritable bowel syndrome. Patients included will be randomly assigned in two groups and subsequently administered with formulation containing Saccharomyces boulardii or placebo for 4 weeks. Patient's quality of life will be assessed by questionnaire at the enrolment and 4 weeks after initiating the therapy.
This Phase IIa study is a 16-week, double-blind, placebo-controlled, randomized study aiming at evaluating the safety and the efficacy of ABX464 given once a day (o.d) at 50 mg in subjects with moderate to severe active Crohn's Disease who have inadequate response, loss of response, or intolerance to prior amino-salicylates, immunosuppressant treatment, biologics, and/or corticosteroid treatment, and followed by a 4 weeks period of follow-up after the last study drug intake.
There is currently no standard management to guide the clinicians in treating patients with fibrostenotic disease. European Crohns and Colitis Organization [ECCO] recently developed a topical review on prediction, diagnosis and management of fibrostenosing Crohns disease. The review suggests endoscopic balloon dilation, strictureplasty, and intestinal resection as reasonable treatment options for short strictures based on the low grade of evidence.
Inflammatory Bowel Diseases (IBD) refers to a category of disorders, consisting of Crohn's Disease (CD) and Ulcerative Colitis (UC), where segments of the gastrointestinal tract become inflamed and ulcerated. Canada has among the highest incidence rates of IBD in the world - 16.3 and 12.3 per 100,000 for CD and UC respectively. In the absence of a cure, the current goal of treatment is to manage patients in a milder state of remission. However, maintaining (or even achieving) remission is dependent on timely access to specialist IBD care; which in light of rising incidence rates have proven to be challenging. Moreover, patients often experience flare-ups of their gastrointestinal symptoms, while awaiting access to specialist care. In recent years, there has been increased integration of telemedicine services in gastroenterology practice. This change has been driven by a desire among IBD patients to have more flexible follow-up care, where 'virtual' care is provided as an adjunct to in-person consultations. Within the context of IBD, telemedicine might be effective in delivering routine and timely follow-up care to high-risk patients. The purpose of this study to determine whether telemedicine-based follow-up care can effectively manage the gastrointestinal symptoms of high-risk IBD patients and reduce their need for preventive health care services.
Some studies have shown that rifaximin is effective in the management of Crohn's Disease. Meanwhile, its adverse effect is tolerable. But no study has been conducted to assess its effect on preventing postoperative recurrence. Thus, we conduct a randomised controlled study to assess the effect of rifaximin on preventing postoperative endoscopic recurrence in Crohn's disease. The primary endpoint is the rate of endoscopic recurrence at 6 months.
