Filter by:Post-surgical physiotherapy programs following to total hip arthroplasty (THA) show important differences between types and numbers of treatment sessions. Objectives are to investigate effectiveness of Fascial Manipulation when associated to a standard protocol of care.
The primary aim of the study is to evaluate the effects of two local cryotherapy (ice or cold gas) applications on arthritic knees. Evaluation criteria (before/after treatment): - synovial power-Doppler semi-quantitative score - pain VAS (mm) - cytokine levels in synovial fluid - leukocyte count in synovial fluid
This Phase IIIb/IV, two-arm, randomized, double-blind, placebo-controlled, parallel-group, international, multicenter trial compares the change in disease activity (as assessed by Disease Activity Score in 28 joints [DAS28] erythrocyte sedimentation rate [ESR]) from randomization to Week 24 post-randomization, in participants with stable low disease activity [LDA] (DAS28 ESR score less than or equal to [<=] 3.2) who receive tocilizumab, and have been randomized to either continue or taper prednisone in a double-blinded fashion.
Naïve CD4+ helper T (Th) cells, upon encountering their cognate antigens presented on professional antigen-presenting cells, differentiate into different effector cells: - Th1 cells produce Interferon-γ and regulate antigen presentation and immunity against intracellular pathogens; - Th2 cells produce IL-4 (Interleukin-4), IL-5 and IL-13, and mediate humoral responses and immunity against parasites; - Th17 cells produce IL-17, IL-17F and IL-22 and regulate inflammatory responses by tissue cells. An additional TH subset called follicular helper T (Tfh) cells has recently been identified in germinal centers and also in whole blood (circulating Tfh cells). These cells regulate B-cell maturation and immunoglobulin production during normal immune responses. They produce factors essential for B cell selection and maturation into memory B-cells or long-lived antibody-secreting plasma cells. Furthermore, they also seem to favor pathogenic autoantibody production in systemic autoimmunity, and therefore could potentially represent a novel therapeutic target in autoimmune diseases. Indeed, rheumatoid arthritis synovium is characterized by the presence of ectopic lymphoid structures, resembling germinal centers. Potentially, Tfh cells from these nonlymphoid tissues could promote B-cell maturation and synthesis of pathogenic autoantibody production, thus potentiating tissue injury. Interestingly, production of IL-21 by Tfh cells is implicated in B cell activation, and the same cytokine have been associated with rheumatoid arthritis (RA) pathogenesis. IL-6 blocking therapy significantly reduces signs and symptoms as well as radiological progression in RA. However, so far, it has not been determined which of the pleiotropic IL-6 effects impact the observed clinical response. Recently, Samson et al have demonstrated that Tocilizumab (TCZ) corrects the imbalance between Th17 cells and Treg cells in patients with RA. More interestingly, the group of Hans-Peter Tony has reported the impact of TCZ on B cell compartment. They showed a significant reduction in the frequency of peripheral pre-switch and post-switch memory B cells but also a reduction of serum immunoglobulin levels, that could be the reflect of TCZ on Tfh cells development, circulation and/or function. Most of the work studying the role of IL-6 on Tfh cells development has been performed in mice. They showed that optimal Tfh cells formation requires IL-21 and IL-6, and that cytokines alone are insufficient to drive Tfh cells differentiation. To better understand the impact of IL-6 on human Tfh cells, the investigators would like to conduct a prospective study in patients with active RA and investigated the effects of blocking IL-6 with TCZ on circulating Tfh cells levels and Tfh cells subsets over a 12-week study period. Furthermore, the impact of TCZ treatment on Tfh cells generation will be explored in vitro.
This study will evaluate the optimal dose of tofacitinib needed to achieve low disease activity (LDA) or clinical remission as measured by the CDAI score. Once LDA or clinical remission has been achieved, the structural benefit in reducing erosions, synovitis and bone edema as measured by low field MRI will be determined at the same time period by the use of the OMERACT/RAMRIS scoring system
A study comparing the use of the Pre-filled Pen and Pre-filled Syringe of SB5 in Subjects with Rheumatoid Arthritis.
The purpose of this study is to evaluate the use, usability and feasibility of an Application (App) for patients with rheumatoid arthritis with diary functionalities, in patient-physician interaction.
This is a cross-sectional, observational study examining the factors leading to the therapeutic decision to use MabThera (rituximab) in participants with RA. Routine rheumatology clinical practice data of participants who are being or have been treated with rituximab for RA will be collected and analysed in this chart review.
The aims of this study is to compare the results between patients without severe patellofemoral arthritis and patients with severe patellofemoral arthritis after mobile bearing UKA. The investigators prospective compute the results including anterior knee pain, knee society score, pain score, functional score, range of motion, operative time, blood loss, and component alignment.
The purpose of this study is to examine changes in immune cells and proteins in response to treatment with two approved therapies for Rheumatoid arthritis (RA), abatacept versus adalimumab, both given in combination with methotrexate.
