Many studies have been conducted to evaluate the role of pulse steroids in early rheumatoid arthritis (RA) but no consensus exists. The aim of this study is to study the efficacy of various treatment regimens in early RA. Methods: This is a randomized open-labeled trial. Patients were randomised into three groups. In group A, patients were treated with single drug (methotrexate 15 mg/wk). The patients in Group B were treated with a combination of DMARDS (Methotrexate, sulfasalazine and hydroxychloroquine). The patients in Group C received combination therapy as in group B and 3 pulses of methylprednisolone intravenously.
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
This cross-sectional, non-interventional, retrospective chart review will compare the efficacy and safety of biologic monotherapy and biologic and methotrexate combination therapy in patients with rheumatoid arthritis who have had an inadequate response to prior treatment with disease-modifying anti-rheumatic drugs including methotrexate. Data will be collected from patients who have been on first-line biologic treatment for at least 6 months.
By using functional MRI the investigators have recently shown that TNFi elicit rapid changes in brain function linked to the perception of RA [5]. Functional MRI represents a method allowing detecting tiny changes in neuronal activity by measuring alterations of blood flow in the context of neuronal activation. TNFi rapidly reversed the widespread activation of brain centers involved in pain such as the thalamus and the somatosensoric cortex, as well as those involved in the control, of mood and emotions such as the limbic system. Moreover, as small phase I study with 10 patients with RA showed that high brain activity detected in the functional MRI predicts clinical response to Certolizumab Pegol after 1 month, suggesting the central nervous system activity may be used as a tool to predict response to TNFi [8]. The rationale of this study is to test whether response to TNFi can be predicted by using functional MRI.
The purpose of this study is to assess the impact of JNJ-38518168 on rheumatoid arthritis (RA) disease-related biomarkers in synovial biopsy tissue and blood in participants with active RA despite methotrexate (MTX) therapy and to assess the safety and tolerability of JNJ-38518168 over one year.
Prospective open label crossover self controlled study. The study population will randomly be divided into two groups. The study will take place in Lot Spa Hotel at the Dead Sea in two cycles (one of 16 participants and one of 14 participants) and will be comprised of 3 main stages: 1. Initial exposure to treatment for 14 days excluding Friday and Saturday (each of the two groups will have its own treatment protocol) 2. 12-month washout period 3. Crossover of the two groups and second exposure to treatment for 14 days excluding Friday and Saturday (each of the two groups will have its own treatment protocol). The population in the study will be composed of patients diagnosed and treated for rheumatoid arthritis at the Soroka University Medical Center who are 18 and above of age. The patients will be selected by the PI and his team and addressed regarding their willingness to participate in the study.
The purpose of this study is to evaluate the long-term safety and efficacy of CNTO 136 (sirukumab) in participants with rheumatoid arthritis (RA) who are unresponsive to treatment with modifying antirheumatic drugs (DMARDs) or anti-TNF alpha agents.
This randomized, multicenter, double-blind, parallel group study will evaluate the impact of MTX discontinuation on the efficacy of SC TCZ in participants with moderate to severe active rheumatoid arthritis who have an inadequate response to current MTX therapy. Participants will initiate treatment with TCZ weekly or every 2 weeks along with MTX at a stable dose orally in an open-label manner for 24 weeks. Participants with a disease activity score based on 28 joints (DAS28) less than or equal to (</=) 3.2 at Week 24, will be randomized to either continue receiving a stable dose of MTX or to switch to matching placebo up to Week 52. Participants without a DAS28 score </=3.2 at Week 24, will continue the same treatment in a non-randomized open-label manner up to Week 52.
The purpose of this study is to assess the safety, tolerability and pharmacokinetics of ABT-122 in subjects with Rheumatoid Arthritis.
