Filter by:Metformin has been used clinically for over 50 years, as a glucose lowering agent. Direct and indirect anti-inflammatory effects of metformin have been reported in animal and clinical studies, and this effect is independent of its hypoglycemic effect. Animal studies showed that metformin decreased serum C-reactive protein (CRP) level in atherogenic rabbits and decreased proinflammatory cytokines (interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF-α) in obese mice . Moreover, metformin also suppressed osteoclastogenesis ; this may partially result from decreased expression of inflammatory cytokines that promote osteoclastogenesis in the arthritic joint. The objective of this study is to evaluate the efficacy and safety of addition of metformin to standard disease modifying anti-rheumatic drugs (DMARDs) in patients with rheumatoid arthritis.
This study is a randomized, open-label, fasted, single dose, crossover study to evaluate the pharmacokinetic profiles and safety of CKD-374 5 mg in healthy volunteers.
The aim of this trial is an evaluation of the effectiveness of fasting and a subsequent diagnosis-specific diet change in patients with rheumatoid arthritis in respect to improving rheumatic symptoms and further to investigate possible mechanisms of this improvement.
This study is designed to observed prospectively the efficacy and safety of 6 months treatment of iguratimod alone, or with methotrexate (MTX), hydroxychloroquine (HCQ) and prednisone step by step on Chinese rheumatoid arthritis (RA) and early rheumatoid arthritis (ERA) patients who were naïve or shown insufficiency response or intolerance to DMARDs. If volunteered, patients who completed the 6-month study can continue to follow our plans for 24 months.
TNFi drugs remain the most prescribed first-line biologics for patients with rheumatoid arthritis (RA). However, up to 40% of RA patients fail to respond to TNFi treatment. One explanation of non-response is the development of anti-drug antibodies and low drug levels. Studies have consistently shown that: 1. Serum drug levels of monoclonal antibodies (such as adalimumab, certolizumab, infliximab) and the presence of anti-drug antibodies in samples taken at 3 and 6 months correlate with subsequent response at 12 months. 2. Non-responders and those who develop anti-drug antibodies are less likely to receive concomitant methotrexate or, if they do receive it, are on lower doses than responder groups. However, it has not been proven that knowing that a patient had low drug levels or anti-drug antibodies would have improved the outcome; neither has it been shown that introducing or increasing the dose of methotrexate would reduce the formation of anti-drug antibodies, thereby improving outcome. Observational data has revealed that RA non-responders, who exhibit adequate serum drug levels and no detectable anti-drug antibodies, have lower probability of response to another agent with the same mechanism of action (MOA), and may benefit in switching to a drug with a different MOA (12). RA non-responders, who have low detectable serum trough levels and detectable anti-drug antibodies, may benefit in switching to a less immunogenic drug (13, 14). These patients may have a predisposition of developing immunogenicity against the introduced foreign protein (12). Neutralising anti-drug antibodies against the TNFi etanercept or the T-cell co-stimulation inhibitor abatacept have not been detected (10, 12, 15). Furthermore whilst the use and dose of methotrexate at initiation of TNFi, has been associated with lower levels of anti-drug antibodies in our work and others (10, 16), it is not known if increasing the MTX dose once immunogenicity has developed reduces anti-drug antibodies and leads to improved treatment response. Whilst algorithms have been proposed based on these tests (4, 17, 18), they have not been confirmed in a randomised controlled trial setting to show that the intervention (testing) is effective. Based on our preliminary work in an observational dataset, this feasibility study will allow us to design a definitive study to answer the important issue of whether pharmacological testing can be utilised as robust biomarkers to optimise future patient outcomes. The next essential step, therefore, is to prove that introducing these tests improves clinical outcome. It is very important to do so because some clinicians are already requesting that their immunology laboratories introduce such tests; yet the tests themselves are expensive and have not yet shown efficacy (19). Conducting a clinical feasibility trial is one of the essential first steps in development of a full clinical trial to undertake process evaluation and assess the proposed study design, required number of participants and ensure optimum project completion. The proposed trial is a clinical feasibility trial with the aim to ensure a realistic assessment and capability to conduct the full clinical trial. Participants with RA, commencing adalimumab or certolizumab will be randomised to determine whether providing test results on adalimumab/certolizumab drug levels and anti-drug antibodies at 4 weeks, 3 and 6 months to clinicians caring for patients with RA (n=15 patients) starting on treatment with adalimumab/certolizumab, improves the course of disease activity, compared to standard care (n=15 patients). Clinicians will be provided with feedback and a treatment algorithm. The feasibility of the study will be assessed by a number of factors including evaluation of recruitment, attrition, data completeness and process evaluation. The results will be used to inform the number of participants required to fully evaluate the intervention.
Methotrexate is a key treatment for inflammatory rheumatism. Therapeutic compliance with methotrexate is difficult to measure because of a lack of objective testing; however, therapeutic compliance is essential for the proper management of a patient. The objective is to characterize the kinetics of elimination of methotrexate and its main metabolite7-OH-methotrexate for observant patients according to treatment (dosage, administration) and patient characteristics. Once this kinetics is characterized, it will be considered as a comparison reference to identify non-observant patients that is to say having concentrations lower than the lower bound of the confidence interval of the observed concentrations.
Rheumatoid arthritis is a common type of autoimmune arthritis that is characterized by inflammation of the synovial membranes. Even though any joint can be affected by the disease, cervical spine is often affected, and cervical pain is reported by 40-88% of RA patients, Cervical spine involvement is a feature of long-lasting disease, where atlantoaxial impaction with odontoid process vertical subluxation through the foramen magnum being one of the greatest and dangerous complications
By forming the foundation of a delivery system that integrates primary care (PC) and rheumatology, this initiative strives to strengthen the roles of both primary care and rheumatology practices as they co-manage patients in a quality care delivery system. Importantly, it strives to fill an unmet need, the rapid evaluation by Primary Care providers; the appropriate and timely referral of inflammatory disease patients to a rheumatologist; and the implementation of early aggressive therapy in the management of patients with rheumatoid arthritis (RA) with tight control. Given the call for improved quality, value, and demonstration of results[1], this initiative uses the tenets of National Center for Quality Assurance's Patient Centered Specialty Program[1] (PCSP) and it successfully masters and streamlines coordination of care.
MRI has been shown to be helpful in identifying patients who present with undifferentiated inflammatory arthritis who will develop RA within a one year follow up period. The absence of other clinically apparent symptoms often causes delays in diagnosis of RA. The use of the MRI in conjunction with the physical examination has the potential to reduce diagnostic delay. Earlier diagnosis would allow for earlier treatment implementation for better patient outcomes.
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterised by polyarthritis and erosive synovitis. Articular and extraarticular sympthoms are mostly seen in patients with RA. Additionally, extra complaints such as depression, fatigue, kinesiophobia and physical inactivity may accompany. Positive effects of physical activity and exercise are known. In some studies, effects of pilates exercises have been investigated on many different diseases such as Multiple Sclerosis, Ankylosing Spondylitis and breast cancer. The aim of this study is to investigate effects of clinical pilates exercises on fatigue, depression, aerobic capacity, pain, quality of life, disease activity and sleep quality.
