Filter by:Clinical data about psychological impact of quarantine are well studied in transient event or more prolonged situation like jail incarceration. In recent metaanalysis, psychological impact of quarantine was well documented in a specific population during first SARS epidemy. Even after the end of quarantine several patients were still with symptom of avoiding mainly agoraphobia, frequent hand washing and a carefull return to normal life COVID-19 infection is already associated with psychological symptom like anxiety, depression, sleep disorders and symptoms of acute stress However psychological impact of quarantine is on none in chronic painful inflammatory rheumatism in France. The prevalence of rheumatoid arthritis is 0.5% of the population with frequent comorbidity such as anxiety and depression. During the quarantine secondary to COVID-19 pandemic it's possible to evaluated the psychological impact of adult RA patients. The present study is an "emergency" being realize before the end of the quarantine.
Rheumatoid arthritis (RA) is a condition associated with a high incidence of cardiovascular disease (CV), primarily as a result of accelerated atherosclerosis . Patients with RA also have a high prevalence of metabolic syndrome (MS) The state of chronic inflammation in RA patients contributes to increased CV risk. Deregulation of both genetic and serological adipocines, MS biomarkers, and biomarkers of endothelial activation and inflammation also contributes to the increased CV risk in these patients. An increased incidence of abnormal carotid intima-media thickness (cIMT) values and carotid plaques, considered surrogate markers of subclinical atherosclerotic disease, has also been described in patients with RA. Positron emission tomography/computed tomography (PET/CT) is a noninvasive imaging technique useful for the evaluation of inflammation (by 18F-FDG uptake) and mineralization (by 18F-NaF uptake) in carotid atheroma plaque. Atherosclerosis and RA share many common inflammatory pathways, and the mechanisms that lead to synovial inflammation are similar to those seen in atherosclerotic plaque. Interleukin (IL)-6 is a key pro-inflammatory cytokine involved in both the pathophysiology of RA and the development of atherosclerosis. Sarilumab is a human monoclonal antibody against the IL-6 receptor that has been shown to be effective in patients with RA, improving symptoms, as well as at the functional and radiographic levels. Treatment with IL-6 receptor inhibitors has been described to result in a modulation of lipid metabolism, mediated by a reduction in lipoprotein (a) (Lp(a)) and an improvement in the anti-oxidant function of high-density lipoprotein (HDL) . In this regard, Sarilumab may have beneficial effects in RA patients on MS, which is implicated in the development of atherosclerotic disease. Information regarding the beneficial effect of IL-6 receptor blockade on atheroma plaque formation and its effect at the vascular level in RA patients is scarce.
This study is a multicenter, retrospective and prospective, non-controlled, non-randomized post market clinical follow-up study. The objectives of this study are to confirm the long-term safety, performance and clinical benefits the Exception Cementless femoral stem (standard and varized) when used in primary total hip arthroplasty.
This study aims to evaluate the experience of Alberta patients with inflammatory arthritis who participate in the the RAPPORT-ONTRAAC registry during the COVID-19 pandemic, specifically comparing the experience of those taking anti-malarial medications compared to those who do not. This registry includes approximately 2500 northern Alberta patients with inflammatory arthritis who receive highly complex therapies which may be associated with side effects. This program of data collection and research has been evaluating the effectiveness and safety as well as associated health care costs of rheumatoid and psoriatic arthritis patients since 2004. The principle investigators are based at the University of Alberta while the co-investigators are academic rheumatologists at the University of Alberta. The registry has approximately 900 patients taking anti-malarials combined with their complex therapies and ~ 1500 not on anti-malarials in combination with their complex therapies. We aim to perform a case control study evaluating the impact of anti-malarial drugs (eg. hydroxychloroquine and chloroquine) on the development of COVID-19 compared to those patients who are not on anti-malarial drugs over the next 6-12 months. In addition to frequent e-mail surveys screening for the clinical symptoms of COVID-19 and understanding their concomitant arthritis medication use, we will compare the healthcare outcomes of both groups of arthritis patients with and without COVID-19 for the duration of the pandemic. This information will provide critical information beyond an anecdotal level on whether or not anti-malarials truly provide a protective benefit against COVID-19 or reduce the severity of infection. A blood sample from all participants (Covid-19 positive and negative) will be drawn approximately six months into the study for measurement of antibodies to Covid-19 and possible blood types and HLA alleles. Additionally, this study will be linked to another study "Persistence of SARS-Cov2 in immunocompromised patients" which will specifically evaluate COVID-19 serology and nasopharyngeal swab findings in the subset of patients who develop COVID-19.
This epidemiological, transversal, cohort study aims to determine the potential influence of an active long-term hydroxychloroquine intake over the prevalence of a history of symptoms evocative of a COVID-19 infection in patients with a history of systemic lupus erythematosus, rheumatoid arthritis, Sjogren's syndrome or psoriatic arthritis, during the epidemic period in France. The information is gathered using a standardized questionnaire, by phone call.
The objective of this study is to identify a panel of immunological molecular and cellular biomarkers able to predict the success of major dose-reduction or discontinuation of abatacept in rheumatoid arthritis patients
This is a prospective, multicenter clinical study designed to facilitate the collection and evaluation of surgical workflow efficiency, patient pain and function outcome and adverse events data. This study might include Persona, Nexgen and Vanguard product families using the ROSA Total Knee Robotic system or conventional instrumentation. The primary objective is to evaluate the accuracy of implant alignment for ROSA Total Knee robotic instrumentation compared to conventional instrumentation.
The trial is a prospective, observational study aiming to identify risk factors for serious COVID-19 infection by evaluating clinical measures and biomarkers of inflammation in patients with inflammatory rheumatic disease hospitalized with COVID-19 compared with control groups.
This study is to evaluate the efficacy and safety of different doses of JAK1 inhibitor SHR0302 in subjects with moderate to severe active rheumatoid arthritis who had inadequate response to conventional synthetic DMARDs.
Objectives: To elucidate the effects of achieving sustained simple disease activity index (SDAI) remission in the progression of joint space outcomes using high-resolution peripheral quantitative CT (HR-pQCT) in patients with early rheumatoid arthritis (ERA), and what the independent effects of erosion /JSW progression are on patient's function. Hypothesis to be tested: Effective control of inflammation in ERA patients who can achieve sustained SDAI remission will have less progression of joint damage then patients who cannot achieve sustained SDAI remission. Design and subjects: 110 consecutive ERA patients will participate in this 1-year prospective, hospital-based, cohort study. Study instruments Metacarpophalangeal joints 2-4 will be measured using HR-pQCT Interventions All participants will receive 1-year tight-control treatment according to a standardized protocol aiming at SDAI remission. Physical function will be assessed by Health Assessment Questionnaire (HAQ) at each visit. HR-pQCT and radiographs will be performed at baseline, 6 (HR-pQCT only) and 12 months. Quantitative analysis of joint space width (JSW) and volume, erosion number and volume, and marginal osteosclerosis (bone apposition at the base of the erosion) will be evaluated by HR-pQCT. Radiographic progression will be scored using van der Heijde-Sharp (SvdH) score. Outcome measures: The primary outcome is the change in JSW and volume over a period of 12 months. Main secondary outcomes include changes in the i) number and size of erosion, ii) SvdH score and iii) HAQ over a period of 12 months. Expected results: Patients who can achieve sustained SDAI remission will have less joint damage and functional loss compared
