Filter by:This study is designed to explore the expression of cell-surface markers in the following seven disease areas: (a) systemic lupus erythematosus, (b) Sjogren's syndrome, (c) multiple sclerosis, (d) systemic sclerosis, (e) Crohn's disease, (f) ulcerative colitis and (g) inflammatory myositis.
BACKGROUND: Previous studies of short-term surgical outcomes after preoperative exposure to anti-TNF therapy in ulcerative colitis (UC) patients who have undergone IPAA have been conflicting. We sought to determine whether preoperative exposure to anti-TNF therapy affects histological measures of fibrosis in the colorectum, which may be a potential factor in adverse anastomosis complications following IPAA surgery. METHODS: Individuals who received infliximab as maintenance therapy and who received their last dose within 180 days of the first stage of IPAA were selected. The control group comprised UC patients who were not exposed to anti-TNF therapy, matched by age, sex, BMI, disease duration, albumin levels, and post-operative leak outcome. Hematoxylin and eosin- (H&E) and trichrome-stained slides from the most distal, well-oriented, full-thickness section of colorectum from each patient's total colectomy specimen were evaluated. Blinded assessment of the degree of fibrosis in the lamina propria, the submucosa, the submucosa immediately adjacent to the muscularis propria, and the subserosa was performed by a single observer using a semi-quantitative pictorial scale.
In Canada and worldwide there is a need for updated independent real-world comparative effectiveness and safety data related to biologic drugs including biosimilar drugs. Biosimilar drugs hold potential to improve access to needed therapies at reduced cost enabling savings to be reallocated to other needs. However updated real-world evidence on comparative effectiveness and safety of biosimilar drugs is lacking. Investigators aim to demonstrate feasibility of creating network of clinical cohorts and other resources to provide real-world information on use of biosimilar drugs in Canada. The core revolves around clinical datasets but investigators will complement with other data sources. Investigators will review data from National Prescription Drug Utilization Information System database that contains prescription claims-level data collected from publicly financed drug benefit programs in different provinces to conduct an environmental scan of the use of biosimilars and respective legacy drugs and other anti-Tumor Necrosis Factor agents covered by provincial drug plans from 2014-2017. Initial analysis will help to confirm that use of biosimilars is lower than corresponding legacy drugs. Biologic drugs are relatively new and expensive drugs; biosimilar medicines are similar to original biologic drugs but cost less. If patients receive biosimilar drugs rather than originator biologics healthcare systems may be able to save money. Those savings can be used for other health care needs to benefit more Canadians. However investigators do not have detailed information on safety and effectiveness of these biosimilar drugs. The aim of study is to compare safety and effectiveness of biosimilar drugs to originator biologic drugs. Investigators will study patients with inflammatory rheumatic diseases (RA and AS) and Inflammatory Bowel Disease (CD and UC) and across Canada on these drugs. Primary focus is on patients without history of biologic drug use but investigators will also study patients switching to biosimilar drug from an originator biologic drug. Investigators will measure how long patients stay on treatment, if patients require new treatment, if the patients' disease control improves and occurrence of side effects such as infection that could be related to these drugs.
Vedolizumab (VDZ) is a monoclonal antibody that binds to the heterodimer α4β7 integrin and which has shown its efficacy in Ulcerative Colitis (UC) by inducing and maintaining clinical response/remission. The French marketing authorization was obtained for Ulcerative Colitis in patients in failure with anti-Tumor Necrosis Factor (anti-TNF) agents. In the pivotal study, correlation between drug levels and clinical response during induction and maintenance therapy were reported. Moreover, in 3.7% of cases, anti-vedolizumab antibodies were reported during the time-course and 1% had samples that were persistently positive. Up to now, data on the pharmacologic VDZ parameters are scarce and the relationships as well as the predictive value of the measurement of VDZ concentrations and VDZ monoclonal antibodies (mAbs) during the induction and maintenance phases remains unknown. It could be of paramount interest to early identify UC patients under VDZ who will be responders to VDZ induction and to identify those who will achieve clinical remission under maintenance therapy with VDZ.
The cause of Inflammatory bowel disease (IBD) is unknown, but intestinal bacteria-involved in the production of molecules that impact health-are widely accepted to play a key role. A significant proportion of IBD patients with pouches (surgically created rectums after the diseased colon is removed) continue to have inflammation similar to their previous disease. Only a few microbes are known to have the capability to modify primary bile acids (PBAs) made by the liver to secondary bile acids (SBAs). SBAs are some of the most common metabolites in the colon and play key roles in several diseases. In this study the investigators will investigate if ursodeoxycholic acid (UDCA) may reduce inflammatory markers and improve quality of life (as assessed by validate survey) in those subjects with active antibiotic refractory or antibiotic dependent pouchitis.
This is a phase I-II study with the herbal formulation (HF2) for treatment of active ulcerative colitis This will be a two-stage study: Stage 1 will comprise an open label single arm exploratory study of 10 active ulcerative colitis (UC) patients investigating oral HF2 therapy for induction of remission in outpatients with active UC. Active disease is defined as (SCCAI) score ≥5 and a score of ≥2 in the modified Mayo endoscopic sub-score. Clinical remission is defined as a SCCAI score of ≤2 The patients will receive HF2 therapy for 4 weeks. Stage 2: If clinical response (defined as a drop of ≥3 points of the SCCAI score ) is achieved in ≥ 3 patients and no significant safety signals will emerge, the investigators will proceed to a prospective pilot randomized placebo-controlled study. Patients will be randomized into one of two arms: HF2 once daily or placebo formulation (2:1 proportion) for 8 weeks. The primary outcome for stage 2 is a co-primary outcome of clinical response (reduction in SCCAI of ≤3 OR achievement of clinical remission defined as SCCAI ≤2) coupled with an objective evidence of response (Mayo score improvement of ≥1 or 50% FcAL reduction) at week 8. Patients clinically responding at week 8, will be eligible to continue in an 8-weeks extension study to receive either placebo or 1.5gr/day curcumin alone until week 16, as per their original allocation. Exploratory analysis of outcomes for the extension study will include the percentage of patients in clinical remission (SCCAI≤2) and the percentage of patients who maintained clinical response (reduction in SCCAI of ≥3 point compared to week 0).
7 patients with active Ulcerative Colitis are treated with 25 multi-donor FMT Capsules daily for 50 days.
The purpose of the study is to confirm that V565 enters inflamed tissue, binds to TNF and reduces inflammation after oral dosing to patients with IBD.
The aim of this study is to assess the ability of miR-320a and other specific microRNAs to follow the disease course in patients with Crohn`s disease (CD) and ulcerative colitis (UC), and to distinguish both entities, infectious colitis and healthy controls. Furthermore, the accuracy of miRNA-320a to distinguish CD or UC from irritable bowel syndrome (IBS) should be evaluated . The study is designed as a single center non-randomised prospective trial.
The purpose of the protocol is to assess the effectiveness of Etiasa® for preventing relapse in Chinese patients with quiescent UC.
