Active clinical trials for "Arthritis"

Rheumatoid arthritis is a chronic systemic inflammatory and autoimmune disease, characterized by disordered immunity, not regulated cytokines and inflammatory infiltration of the synovial joints. It is the most common inflammatory erosive poly arthritis affecting around 0.5-1% of the worldwide population which leads to joint damage and disability

Background: Patients with inflammatory arthritis (IA), such as spondyloarthritis (axSpA), rheumatoid arthritis (RA) or psoriatic arthritis (PsA) are more prone to physical inactivity but derive specific benefits from regular physical activity. Barriers and facilitators to physical activity (B&F-PA) are key elements and knowledge of their correlation to physical activity is essential for developing interventions to promote physical activity that have a greater likelihood of success. Objectives: primary objective will be to measure the correlation of these B&F-PA to physical activity collected through apps. Secondary objective will be to (I) to quantify physical activity collected through apps in IA patients and (II) to observe the link between physical activity, B&F to physical activity and adherence to treatment. Patients and methods: This is an international, multicentric, cross-sectional study. Patients: From the first of September to the first of February 2020, all patients with definite axSpA, RA or PsA, aged above 18 and able to walk, who have a mobile phone compatible with apps that can track steps, who agree to participate and give his oral informed consent and with ability to read and write in the language of the participating country, seen in outpatient visits in the participating centers, will be asked to participate. The planed inclusion was 200 participants. Data collection: clinical data and information about physical activity and B&F-PA will be entered by rheumatologists during or electronically by patients at the same time point. Questionnaire for B&F-PA: a patient reported questionnaire was recently developed for this study in 2019 based on a systematic review to identify the main B&F-PA. A list of questions was generated from the systematic review reviewed and tested for face validity by 11 experts and confronted to 20 patients with IA through a cognitive debriefing. Physical activity: Physical activity will be measured objectively during the last 7 days by apps already installed by default on the mobile phone of participants and subjectively with the International Physical Activity Questionnaire short version (IPAQ-S). Other outcomes: Stage of exercise behavior change and adherence to treatment will also be collected. Planned analyses: Perceived B&F-PA will be described using frequencies. A score will be calculated for each participant representing the limitations or facilities to perform physical activity. Analysis of the physical activity: The distribution of mean number of steps will be assessed visually for outliers. Univariate analysis will be completed between mean number of steps and gender, age, disease and stages of change. Correlation between mean number of steps and IPAQ-S score will be calculated. Link between physical activity and barriers and facilitators: The link between B&F questionnaire score and mean number of steps will be tested using linear regression. Then multivariate regression including demographic variables, psychological status and disease characteristics will be performed. Outcomes of the study: The expected outcomes of the ImBAIA study are a better understanding of B&F to physical activity in patients with IA and their impact to limit or to favor physical activity. We also expect to observe the level of physical activity of an IA population objectively measured with apps. Finally, a validation was expected to use questionnaire of B&F.

The current situation of Sars-Cov-2 pandemic generates fears in the general population. Among patients receiving long-term immunomodulatory drugs, especially in the context of auto-immune diseases, there may be legitimates interrogations about the appropriateness of continuing treatment, without modification, in the current context. Juvenile Idiopathic Arthritis is concerns by these fears (the patient and their parents). Patients are treated by several classes of immunomodulatory drugs, including non-steroidal anti-inflammatory drugs, corticosteroids and disease modifying anti-rheumatic drugs. The present study will characterize this issue by defining the proportion of patients whose usual treatment of Juvenile Idiopathic Arthritis has been modified in relation to the actual sanitary crisis, and also to return to school.

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic and aggressive polyarthritis. The prevalence of RA in China is about 0.42%. Arthroscopic synovectomy (AS) is an important method to save the function of joint in the treatment of refractory RA. The clinical trial is to study the value of AS combine with DMARDs in the early stage of refractory RA.

The purpose of this study is to determine how interstitial lung disease can be predicted over time in early rheumatoid arthritis. The investigators will study blood and phlegm samples from participants, along with quality of life questionnaires to determine if and how the presence of ILD may impact the participants quality of life over time.

The purpose of this study is to analyze pre- and intra-operative joint aspirates of native joints and joints with suspicion of periprosthetic joint infection (PJI) of the hip, knee and shoulder acquired in clinical routine. Joint aspirates are then analyzed with new diagnostic methods (microcalorimetry, PCR, alpha-defensin, etc.). Diagnostic speed and accuracy of these methods is compared to standard diagnostic methods in clinical routine, such as blood cultures of joint aspirates, cell count/differential, intra-operative tissue culture and histology and sonication.

Rheumatoid arthritis(RA) with a high incidence and high morbidity, the pathogenesis has not been fully elucidated. Fibroblast-like synovial cells excessive proliferation and synovial angiogenesis is the most important cause of RA synovitis and joint destruction. Our study was to find the role of Sonic Hedgehog(SHH) pathway in regulating proliferation of fibroblast-like synovial cells and modulating excess angiogenesis of synovial tissue.

Measuring lung function (FVC, FEV1, DLCO) before, during and after treatment with rituximab in patients with rheumatoid arthritis or inflammatory myositis.

The investigators are doing this study to look at sleep problems, daytime sleepiness, and thinking and behavior patterns in children with arthritis and in children without arthritis. Arthritis is a problem with joints. Some children have arthritis and some children do not have arthritis. Sleep disordered breathing is a sleeping problem in which some children snore and have pauses in their breathing during sleep. It is associated with not enough or fragmented sleep, poor school performance, problems paying attention, and behavior problems. The investigators do not know how many children with arthritis have sleep problems, and how it is linked to daytime sleepiness and children's learning, and behavior patterns compared to children without arthritis. The investigators need to study both children with arthritis and children without arthritis to learn more about these connections and to understand if they are the same or different in children with arthritis and in children without arthritis.

The purpose of this study is to evaluate ultrasound hands in patients with systemic lupus erythematosus.
