Filter by:The purpose of this study is to obtain biologic materials from the blood, airways and/or urine of normal individuals and individuals with lung disease. The normal are used to establish a set of normal ranges for various parameters. These provide control information when compared to individuals with various pulmonary diseases, and will help in understanding of the etiology and pathogenesis of various lung diseases. The underlying hypothesis is that the pathologic morphological changes in the airway epithelium must be preceded by changes in the gene expression pattern of the airway epithelium and potentially in macrophages.
1. Investigate Gleno-Humeral Joint (GHJ) by anterior approach: A - Measurement of GHJ thickness at 3 points and average value calculation on body supine position and with arm supinated, maximal externally rotated with elbow angle 90 degrees - By longitudinal access with transducer position laterally to coracoids along to the GHJ line, located as diagonal form lower to forward and lateral direction with demonstration the joint cartilage posteriorly and subscapular tendon anteriorly (Fig.4) - By transversal access with 90 degrees to longitudinal and at 3 points: upper with coracoids visualization, middle and lower (Fig.5-7). B - Measurement of rotator interval with assessment of width and higher. 2. Comparison of the data with results of classic values have been received by posterior and inferior (axillar) approach. 3. Comparison of the results between patients with Rheumatoid Arthritis (RA) and healthy controls
Compare the efficacy of adding small doses of prednisolone (10 mg) daily to the efficacy of adding one of the available anti TNF in the treatment of methotrexate inadequate responder rheumatoid arthritis patient. Hypothesis: Methotrexate + Prednisolone vs. Methotrexate + anti TNF
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
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 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.
