Methotrexate and Metformin in Rheumatoid Arthritis Patients
ArthritisRheumatoidMethotrexate (MTX) is the anchor drug for patients with rheumatoid arthritis (RA). Despite its marked efficacy and acceptable side effect profile, about 1/3 of patients failed to reach RA remission. Metformin is the first-line therapy for type 2 diabetes. Its antioxidative and anti-inflammatory properties make it a good candidate for the treatment of inflammatory diseases such as rheumatoid arthritis.
The Ondansetron Premedication Trial in Juvenile Idiopathic Arthritis
Juvenile Idiopathic ArthritisFar too many kids and families live in dread over the weekly nausea and vomiting caused by methotrexate - a medicine that controls joint swelling in Juvenile Arthritis patients. If methotrexate is not tolerated, expensive alternative biological medications may be started. This registry-based pragmatic randomized controlled trial will evaluate if routine premedication with the anti-emetic drug Ondansetron, reduces nausea and vomiting and increases the proportion of children able to continue methotrexate. By preventing nausea before it starts, the investigators hope to give kids and families a better quality of life and see a more cost-effective use of medication.

Study on Shoulder Arthritis Treatment With Intra-articular Injections of Autologous Bone Marrow...
Shoulder ArthritisTreatment of isolated osteoarthritis of the glenohumeral joint at the initial stages involves the use of numerous conservative or arthroscopic treatments with uncertain results and, upon their failure, the current solution for the resolution of symptoms is shoulder arthroplasty, an effective procedure but with significant costs and rates of morbidity, especially in young patients. Since the use of intra-articular injections of mesenchymal cells obtained from the bone marrow has proved effective in the treatment of gonarthrosis, our goal is to evaluate the effectiveness of the same therapy in the treatment of glenohumeral arthritis isolated.

BIOTIPRA: BIOmarker-guided Treatment Decisions In Psoriatic and Rheumatoid Arthritis
ArthritisRheumatoidTNFi 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: 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. 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.

Study of Personalized Instrument in Total Shoulder Arthroplasty The P.I.T.S.A. Study
Shoulder ArthritisTotal shoulder arthroplasty is an effective procedure to improve patients function and to relieve shoulder pain in cases of glenohumeral arthritis. The main challenge of this procedure is implanting the glenoid component. Indeed, surgical exposure is difficult and proper visualization of the glenoid is demanding. The current free-hand method is not precise and especially unreliable in glenoids with severe deformity. Inappropriate reaming and glenoid positioning can cause more bone loss during surgery. In anatomic prostheses, glenoid component fixation is demanding and is the first component to present loosening at long term follow-up. When it comes to reverse arthroplasty, the glenoid component, once again, requires the most attention. Malpositioning of the glenosphere can cause notching, loosening, and instability. In order to prevent these complications, precision in glenoid implantation is key. To this end, intraoperative computer navigation would be a helpful tool, but the increased expenses in computer equipment represent massive costs and possibly increases in surgical time. A more affordable option is a personalized guide, for which the only extra expense is the customized guide. These guides are based on precise 3D CT scan templates. Previous studies have evaluated the precision of the guide in vivo and in vitro, but none have measured it in a randomized study. As it represents additional costs, its efficacy needs to be proven before widespread use. This method may also provide secondary benefits, such as decreasing operating time, lowering short- and long-term complications, and improving efficacy. The objective of this study is to evaluate the performance of a patient specific glenoid guide.
