Filter by:This is an open-label positron emission tomography/computed tomography ( PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-BNOTA-PRGD2 in rheumatoid arthritis (RA) patients. A single dose of nearly 111 MBq 68Ga-BNOTA-PRGD2 (≤ 40 µg BNOTA-PRGD2) will be intravenously injected into patients with RA. Visual and semiquantitative method will be used to assess the PET/CT images. Whole body 18F-FDG PET/CT will be performed for comparison.
the purpose of the study is to assess the safety and efficacy of commonly used Homeopathic medicine Rhustoxicodendron in 30 potency in the treatment of Rheumatoid arthritis.
The purpose of this study is to evaluate the efficacy of Iguratimod versus placebo on synovial inflammation,bone erosion and bone edema as measured by MRI of wrist and Metacarpophalangeal joints in patients with early Rheumatoid Arthritis (RA).
In recent years, ion channels have emerged as new therapeutic targets for pain. Among these channels, ASICs (Acid Sensing Ion Channels) are of particular interest because they are directly activated by extracellular acidity, which is a major cause of pain. Indeed, many painful conditions such as ischemia, inflammation, tumor development or tissue incision are accompanied by tissue acidification. ASIC are excitatory ion channels that are expressed in neurons, including nociceptive sensory neurons. In humans, the use of amiloride, a nonspecific inhibitor of ASICs, has demonstrated their role in the perception of pain induced by subcutaneous injections of acidic solutions. ASICs thus appear as new candidates capable of mediating pain in humans. A growing number of data suggests that, in addition to protons, ASICs may also be activated by one or more endogenous compounds produced during inflammation. The purpose of this research project is to identify these compounds by testing the effects of human inflammatory exudates on ASICs activity. The discovery of such compounds would definitely validate ASICs as novel therapeutic targets for pain treatment in humans
The purpose of this study is to compare the small and large dose of corticosteroid used in intraarticular injection of wrist.
The purpose of this study is to assess the clinical response to IL-6 inhibition defined as Low Disease Activity (DAS44) <2.4) at the follow-up visit at 12 months and the correlation between the biomarkers and treatment response.
The ACR Rheumatology Clinical Registry (RCR) is a tool developed to assist members in practice improvement, local population management, and efficient, successful participation in national quality programs. RCR integrates evidence-based quality measures aimed at improving care and drug safety for patients with rheumatoid arthritis, osteoarthritis, osteoporosis, gout and juvenile idiopathic arthritis.
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
