Active clinical trials for "Arthritis"

Rheumatoid arthritis (RA) patients have a higher prevalence of subclinical atherosclerosis than the general population. In addition, RA patients experience higher rates of heart failure with preserved ejection fraction (HFpEF). There is evidence that myocardial mechanics and left ventricular diastolic function are more abnormal in the RA population and these changes occur earlier than in the general population. Recently a study suggested that RA patient have abnormal myocardial inflammation during a disease flare and that this is improved with anti-inflammatory treatment. This study is aimed at describing the prevalence of myocardial inflammation in patients during active RA disease flares and comparing that with RA patients who are in remission. Investigators hope to show that abnormalities in myocardial inflammation on PET imaging correlate with abnormalities in myocardial strain on echocardiography. Coronary CT will be performed to establish the presence of subclinical atherosclerosis and whether its presence affects changes in either myocardial inflammation or myocardial strain. The hypothesis is that patients with evidence of myocardial inflammation during the course of their RA disease are more likely to develop HFpEF during their lifetime. Although the present study will not be of a duration to assess outcome, it will provide descriptive data which may help guide future prospective study of patients with RA which may help guide appropriate cardiovascular testing in this high risk population.

Prospective, global, multicenter study to assess cup position in THA. After written informed consent has been obtained, study evaluations will be collected from the pre-op clinic visit, the operative visit (including discharge), and 6 and 12 weeks postoperatively.

Patients and physicians often differ in their perceptions of rheumatoid arthritis (RA) disease activity, as quantified by the patient's global assessment (PGA) and by the evaluator's global assessment (EGA). The objectives of this study were: to explore the extent and reasons for the discordance between patients and physicians in their perception of RA disease activity to determine if this discordance at baseline is associated with RA outcomes at 1 year (remission, function and structure) in early arthritis (EA) in daily clinical practice. Patients: from the French cohort of early arthritis (EA) ESPOIR³ (at least 2 swollen joints for less than 6 months, DMARD naïve), fulfilling the ACR-EULAR criteria for RA at baseline Analysis: At baseline, agreement between PGA and EGA (Bland-Altman plot) was assessed. Multivariate linear regression was used to determine the patient and EA features independently associated with discordance (calculated as PGA - EGA). Logistic regression was used to analyze discordance as│PGA - EGA│≥20. Multivariate logistic models were used to determine if discordance at baseline is associated with remissions (Boolean, SDAI and DAS28), functional stability (HAQ≤0.5 and deltaHAQ≤0.25) and absence of radiographic progression (delta Sharp score<1) after 1 year of follow-up.

Observational study

The purpose of this study is to evaluate the association of Rheumatoid Arthritis (RA)-related antibodies and periodontal inflammation in subjects at-risk for Rheumatoid Arthritis. Subjects will undergo periodontal and joint examinations, as well as collection of body fluids to measure Rheumatoid Arthritis-related antibodies.

The purpose of this study is to assess hand functions and wrist joint position sense in patients with and without PsA.

Juvenile Idiopathic Arthritis (JIA)is the most common chronic rheumatic disease in childhood. While JIA usually affects the ankle and knee joints, it can also affect hip, cervical spine and shoulder involvement. Secondary problems such as spine involvement or lack of weight transfer may lead to scoliosis. The aim of this study was to perform scoliosis screening in children with JIA and to evaluate families' awareness of scoliosis.

This study will compare rheumatoid arthritis (RA) patients who have been treated in clinical practice with either infliximab or a combination of sulfasalazine and hydroxychloroquine, after having an active disease despite treatment with methotrexate for at least one month. To establish which patients respond to treatment, DAS28-ESR measurements (disease activity score using 28 joints and erythrocyte sedimentation rate) taken at treatment start and nine months thereafter, and the EULAR (European League Against Rheumatism) definition of a "good response" will be employed. The purpose of the study is to verify if the same conclusion could be reached using data from patients treated in real world clinical practice as in a previous randomized controlled trial comparing the two treatment strategies (SWEFOT -- ClinicalTrials.gov Identifier: NCT00764725). Inclusion criteria similar to the ones used in the emulated trial will be applied. In real clinical practice, patients who receive infliximab may have more severe RA and may also differ in other ways from patients receiving sulfasalazine and hydroxychloroquine. To be able to compare the proportions of responders under each treatment in this "real-world" setting, the data will be re-weighted, so that patient characteristics become balanced between treatment groups.

Patients with inflammatory rheumatism very often have residual pain that is not easily relieved by conventional treatments. They can then use non-drug methods, such as physiotherapy, hypnosis or even cannabis. The aim of this study is to assess the percentage of patients who use cannabis to better relieve their pain or anxiety in chronic inflammatory rheumatism.

It is a prospective case-control study with women diagnosed early rheumatoid arthritis. Three therapeutic failures were considered: failure 1 - to the first Disease-modifying antirheumatic drugs (DMARDs) (methotrexate); failure 2 - to the second DMARDs (leflunomide) and failure 3 - to the first immunobiological drugs (adalimumab). Ultrasound was performed bilaterally on the 2nd and 3rd metacarpophalangeal joints (MCFs), proximal interphalangeal joints (IFPs), and wrists (US10). Ultrasound measurements (qualitative and semi-quantitative) evaluated: 1 - inflammatory: synovial and tenosynovial proliferation in gray scale and power Doppler (0-3); 2 - joint damage: bone erosion (qualitative and semi-quantitative) and cartilage damage (qualitative and semi-quantitative). Clinical and laboratory variables were also assessed blindly at baseline and after 12, 24 e 48 weeks.
