The investigators will study the effects of methotrexate on blood pressure, arterial stiffness and endothelial function in patients with rheumatoid arthritis.
Tendon pathologies (enthesitis) are a characteristic component of psoriatic arthritis (PsA), and are observed in 35% to 50% of PsA patients. The Achilles tendon is one of the most commonly affected sites. This condition often causes great morbidity and loss of quality of life, and response only suboptimal to current intervention strategies. One of the main obstacles for the development of effective treatment methods is that the disease mechanisms remain poorly understood. To our knowledge, no one has yet ascertained the presence and function of immune-competent cells and inflammatory markers in tendons tissue from PsA patients suffering from Achilles enthesitis.
Juvenile Idiopathic Arthritis (JIA) is a disorder of unknown cause characterized by chronic inflammation of the joints and other organs. It affects about 1 in a 1000 Canadian children and if untreated it can produce lifelong disability. The Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) includes most pediatric rheumatologists in Canada. They have successfully collaborated for the past 20 years producing groundbreaking research on the modern course and outcomes of JIA. The CAPRI JIA Registry is an ongoing universal registry of Canadian children with JIA that collects longitudinal data on disease course, outcomes and adverse events to inform healthcare decisions and to gain new insights into the disease and its treatment.
Rheumatoid arthritis (RA) is the most common inflammatory rheumatoid disease in France, affecting 0.3% of the general population. Without effective treatment, the persistent inflammation causes invalidating pain and joint destruction, leading to major functional disability. Biological agents have been proposed for patients with RA who have the most severe form of the disease and that are inadequate responder patients to conventional synthetic Disease-modifying antirheumatic drugs (csDMARDs). TNF inhibitors (TNFi) are historically proposed as the first biological DAMRD for inadequate responder patients to csDMARDs. A diverse therapeutic arsenal has become available in recent years with the development of non-anti-TNFα drugs whose mechanisms of action are different from the classical TNFi. This new biotherapy class includes tocilizumab and abatacept, two drugs recently available for subcutaneous administration that enables ambulatory care for patients who would otherwise require repeated in-hospital care. The role of these new treatments in the therapeutic strategy has been emphasized by studies that demonstrated their efficacy as first-line treatments. However, in clinical practice, TNFi remain the most common first-line treatment for the majority of patients, non-anti-TNFα biological agents being reserved for inadequate responder patients. In second line, several studies have investigated therapeutic strategies for inadequate responder patients to TNFi. Current data suggest that it could be wise to change the therapeutic target after failure of a first-line treatment with TNFi. Data about the comparative efficacy of different biologics proposed after failure of a first-line treatment with TNFi are in progress. Meta-analyses from registries and academic trials conducted in France and The Netherlands suggest that non-anti-TNFα agents would have equivalent or superior efficacy compared with a second TNFi. This finding suggests clinicians to switch for an alternate therapeutic target after failure of a first-line TNFi. Data comparing different non-anti-TNFα biologics in inadequate responder patients to TNFi are scare. Industrial trials have demonstrated sustained biological efficacy of non-anti-TNFα biologics after failure of a TNFi. However, there is very little solid data on the direct comparison between them.
Prospective, multi-centre, non-comparative, post-market surveillance clinical study
Introduction: The medical treatment of inflammatory rheumatic diseases has improved dramatically during the last decades primarily due to the introduction of biological disease modifying anti-rheumatic drugs (bDMARDs). However, bDMARD treatment failure occurs in 30-40% of patients due to lack of effectiveness or side effects. The tools to predict treatment outcomes in the individual patient are currently limited. The objective of the present study is to identify diagnostic, prognostic and predictive biomarkers, which can be used to 1) diagnose inflammatory rheumatic diseases early in the disease course with high specificity and sensitivity, 2) improve prognostication or 3) predict treatment effectiveness and tolerability for the individual patient. Methods and analysis: Observational and translational open cohort study with prospective collection of clinical data and biological materials in patients with inflammatory rheumatic diseases treated in routine care. Patients contribute one cross-sectional blood sample (i.e. whole blood, serum, EDTA-plasma and -buffy coat, and blood in PAXgene RNA tubes) and/or are enrolled for longitudinal follow-up upon start of new DMARD (blood sampling after 0/3/6/12/24/36/48/60 months' treatment). Demographics, disease characteristics, comorbidities and lifestyle factors are registered at inclusion; DMARD treatment and outcomes are collected repeatedly during follow-up. Currently (June 2017) >5,000 samples from ≈3,000 patients have been collected. Data will be analysed using appropriate statistical analyses. Ethics and dissemination: The protocol is approved by the Danish Ethics Committee and The Danish Data Protection Agency. All participants give written informed consent. Biomarkers will be evaluated and published according to REMARK, STROBE and STARD guidelines. Results will be published in peer-reviewed medical journals and presented at international conferences.
The primary goal of this study is to investigate lung disease, through pulmonary function and high resolution chest CT, in newly diagnosed rheumatoid arthritis (RA) patients. Extra-articular disease occurs in approximately 50% of RA patients, with the lung being a common site of involvement. Investigators goal is to understand the prevalence of lung disease in early RA patients and to better characterize it through questionnaires, imaging, and serum studies. Additionally, the goal is to find novel biomarkers to predict lung disease in RA patients.
This research program aims to comprehensively investigate the clinical, physiological, metabolic, and molecular effects of reducing sedentary behavior in rheumatoid arthritis. To this aim, we will conduct a 4-month parallel-group randomized controlled trial aiming to investigate the feasibility and efficacy of a newly developed personalized intervention focused on replacing sedentary time with light-(or very light-) intensity physical activity in rheumatoid arthritis. Additionally, a sub-sample of patients will complete a randomised cross-over study aiming to unravel potential mechanisms underlying the metabolic, physiological and molecular effects of breaking up sedentary time with light-intensity physical activity versus carrying out the minimum amount of daily exercise at once and then remaining sedentary versus simply remaining sedentary throughout all sessions, in a well-controlled laboratorial condition.
Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory autoimmune disease that results in the destruction of joints, connective tissues, muscle, tendons and fibrous tissue. Effective therapy to manage RA still does not exit at present. Jia Wei Niu Bang Zi pill (NBZP) consists of Chinese herbals which has been widely used in the treatment of RA patients in China for hundreds of years to relieve pain and prevent the affected joints pejorative. However, there is no systematic trials to prove the effect of NBZP for management of RA.
