Synovial and Adipose Tissue Composition in Overweight/Obese Patients With Active Rheumatoid Arthritis...
Rheumatoid ArthritisRheumatoid Arthritis (RA) is a chronic autoimmune disease that affects nearly 1% of the general population worldwide leading to joint inflammation, disability and increate mortality. Several factors are associated with disease activity and treatment outcomes. Among them, overweight/obesity status was demonstrated to be associated with higher risk of RA development and most importantly to different treatment response to biological DMARDs. Moreover, overweight/obese RA patients do show higher degree of synovial inflammation compared to lean RA patients. In this context, adipose tissue accumulation is associated with higher inflammatory burden through the secretion by activated mature adipocytes of adipokines with pro-inflammatory properties on innate and adaptive immune cells. Among them, Leptin is an important adipokine, released by mature adipocytes with multiple activating properties on immune cells as monocytes, macrophages, dendritic cells, T and B lymphocytes acting through the activation of its receptor LEPR via JAK/STAT pathway. In particular, leptin exerts its effects on macrophages populations through the promotion of M1 differentiation with pro-inflammatory phenotype. In our research hypothesis we expect that leptin levels does correlate with immunohistochemical scores of synovial inflammatory cells (CD68+, CD21+, CD20+ and CD3+) and CD31+ synovial vessels. Moreover, we expect that the inhibition of JAK/STAT signal using Tofacitinib may interfere with leptin activation action on resident synovial inflammatory cells expressing LEPR (as CD68+, CD20+ and CD3+) in particular restoring the M1/M2 phenotype ratio within resident macrophages populations. Finally, we expect that the inhibition of JAK/STAT signaling pathway by Tofacitinib will result in a significant reduction of synovitis degree in patients with higher leptin expression due to adipose tissue activation.
Lifestyle Intervention for Rheumatoid Arthritis
Lifestyle Risk ReductionRheumatoid ArthritisThe main purpose of this study is to assess whether adding a multifaceted lifestyle intervention to the standard best practice of care can be more effective than standard best practices alone for treating Rheumatoid Arthritis.

ArthritisRheumatoidThe primary objective of this trial is to evaluate the long-term safety of BI 695500 in adult patients with moderately to severely active rheumatoid arthritis (RA) who have successfully completed treatment in Trial 1301.1.
Brigham and Women's Rheumatoid Arthritis Sequential Study
Rheumatoid ArthritisThe goal of the present study is to establish a prospective observational cohort of Rheumatoid Arthritis patients in order to Determine and validate biomarkers that predict drug response and toxicity in RA. Determine and validate biomarkers that predict disease activity and prognosis in RA. Evaluate the natural history of treated RA in terms of its clinical, functional and economic outcomes.
Namilumab vs Adalimumab in Participants With Moderate to Severe Early Rheumatoid Arthritis Inadequately...
Rheumatoid ArthritisThe purpose of this study is to evaluate the efficacy and safety of namilumab in combination with existing methotrexate (MTX) therapy over 24 weeks in participants with moderate to severe early rheumatoid arthritis (RA), diagnosed within 6 months and inadequately controlled by MTX alone.
Zimmer POLAR Persona - TKA (EMEA Study)
Severe Knee PainSevere Knee Disability4 moreThe primary objective of this study is to obtain implant survivorship and clinical outcomes data for commercially available Persona knee implants used in primary total knee arthroplasty. The assessment will include: Implant survivorship based on removal of a study device. Safety based on incidence and frequency of adverse events. Clinical performance measured by overall pain and function, quality of life data, radiographic parameters and survivorship.
