Filter by:Study objectives 1. Comparison of drug persistency rates between elderly RA patients and young RA patients with biological DMARDs 2. Analysis of discontinuation reasons & influencing factors of drug discontinuation in elderly RA patients and young RA patients 3. Comparison of the occurrence of adverse events & treatment outcomes between elderly RA patients and young RA patients
The purposes of this study 1. to compare the positivity of tuberculin skin test(TST) and QuantiFERON-TB Gold (QFT-G), and determine the level of agreement between two tests in patients with rheumatic diseases 2. to evaluate the difference in the occurrence of active TB in patients who receive both QFT-G and TST compared with those who receive only TST for detecting of Latent tuberculosis infection(LTBI) who are candidates of TNF inhibitors.
B cells are known to play an important role in auto-immune diseases by activating T cells, secreting inflammatory cytokines and autoreactive antibodies. However, a sub-type of B cells named regulatory B cells or Bregs has recently shown capacities to prevent or cure arthritis in mouse models. Bregs have also been identified in humans.
Rheumatoid arthritis (RA) is an autoimmune disease of unknown etiology characterized by peripheral polyarthritis, symmetric, which leads to joint destruction and deformity. It is estimated that the RA reaches about 0.5% of the population. According to data from DATASUS, was responsible for 26,671 hospitalizations, 229 deaths and cost exceeding R$ 20 million in 2005-2007. The main bodily changes are related to joint problems, however, systemic manifestations are also found in organs such as lung and heart. Although cardiovascular diseases are the most responsible of the deaths AR, pulmonary complications are common and account for 10% to 15% of all mortality. Anaya and colleagues point out that the pulmonary involvement contributes significant morbidity and mortality in these patients. Although pulmonary involvement is a frequent manifestation in RA, the prevalence and nature of rheumatoid lung disease has not yet been precisely established. Several lung disorders such as interstitial pulmonary fibrosis, pulmonary nodules and bronchiolitis may ocorrer1. Laitinen et al point out that studies of lung function appear to be a valuable helper for radiography in the evaluation of pulmonary involvement in connective tissue diseases. Previous studies indicate that patients with RA have an increased incidence of abnormal lung function, according to assessments including spirometry, lung volume tests and diffusion capacity of carbon monoxide. Thus, the main objective of this study is to analyze the respiratory mechanics of patients with RA. Specific objectives were to seek to understand whether a relationship exists between duration of rheumatoid disease and lung function in these patients. For this, the investigators used 18 subjects in the control group, free of pulmonary disease and / or heart, all nonsmokers. In the RA group, a total of 72 patients divided into 4 groups of 18 volunteers each, classified according to disease duration (0-5 years, 6-10 years, 11-15 years and> or = 16 years). It is noteworthy that all patients in the RA group will also be non-smokers, since it is already known in the literature that smoking impairs lung function. All individuals will perform the function test with a trained technician and qualified to function. The examinations will be conducted: Forced oscillation technique and spirometry, in that order.
There is a group of patients with rheumatoid arthritis (RA) that suffer from chronically painless synovitis in the hands. The objective of this study is to compare painless synovitis with painful synovitis according to the sonographic (Gray-scale and power Doppler) findings. A sonographic examination (Gray-scale and power Doppler) will be done to evaluate metacarpophalangeal joints of patients without local painful and will be a comparison with patients with local painful.
Measuring lung function (FVC, FEV1, DLCO) before, during and after treatment with rituximab in patients with rheumatoid arthritis or inflammatory myositis.
This study was intended to assess the efficacy and safety of different Disease-Modifying Antirheumatic Drugs cycle combination regimen using the American College of Rheumatology (ACR) criteria of 20% improvement in symptoms (ACR20) in managing active adult rheumatoid arthritis.
The present study aims to evaluate the effect of insoles for foot arthritis.
The biologic drugs targeting TNFa, IL-6, IL-1, T cells, B cells have represented a fundamental discovery to treat rheumatic patients whose disease appears to be refractory to conventional therapy. These biologic drugs have been registered for human therapy from a few years, thereby the investigators miss long-term data for safety and efficacy. Aim of this study is to register all the clinical data of patients with rheumatoid arthritis and spondyloarthritis beginning a treatment with biologic drugs in order to assess the long-term safety and efficacy in the real life.
Resistance exercise plus vascular occlusion may induce greater improvements in strength and muscle mass resistance training alone. The investigators speculate this training strategy could be beneficial in patients with rheumatoid arthritis.
