Active clinical trials for "Arthritis, Rheumatoid"

Evaluation of Health Related Quality of Life (HRQL) is of a paramount importance in assessing the impact of rheumatoid arthritis on patients' health status, however when costs associated with rheumatoid arthritis are also taken into account, the information provided may lead to a more balanced view in analyzing the treatment of the disease. In accordance with the above, the main objective this study was to evaluate the impact of adalimumab treatment not only on patients' Health Related Quality of Life but also on the cost of the disease management. In order to accomplish this the study has been focused on: Estimating the direct and indirect cost incurred by adalimumab treatment. Measuring the Health Related Quality of Life of rheumatoid arthritis patients under adalimumab treatment. Exploring the cost-utility relationship of rheumatoid arthritis patients treated with adalimumab by combining the Health Related Quality of Life of rheumatoid arthritis patients and direct as well as indirect costs due to RA. More specifically, data related to patients' Health Related Quality of Life and cost associated with rheumatoid arthritis will be recorded for one-year period, and collected at four subsequent visits: baseline, month 3, 6 and 12. The visit before starting treatment with adalimumab will be considered as baseline. This information was used to compare Health Related Quality of Life and cost data before and after adalimumab initiation and therefore identify the effect of adalimumab treatment in patients with rheumatoid arthritis.

The purpose of the OTIS Autoimmune disease in pregnancy study is to monitor planned and unplanned pregnancies exposed to certain medications, to evaluate the possible teratogenic effect of these medications and to follow live born infants for one year after birth. With respect to fetal outcome, it is important to evaluate the spectrum of outcomes that may be relevant to a medication exposure during pregnancy, and these include both easily recognizable defects that are visible at birth, as well as, more subtle or delayed defects that may not be readily identifiable without special expertise and observation beyond the newborn period.

primary endpoint of this Study is maintenance of "at least good clinical status" for a period of 10 years following initial implantation among Cormet procedures enrolled inthe pre-market IDE.

This study will be performed to evaluate and document the safety and efficacy of infliximab (Remicade®) in the treatment of chronic inflammatory diseases in big cohorts in the daily routine practice of rheumatologists, gastroenterologists, and dermatologists.

The purpose of this study is to develop a registry with safety and efficacy data on the use of etanercept in clinical practice in Taiwan.

This protocol is designed to evaluate the BRADA and ABILHAND questionnaires in rheumatoid arthritis (RA) patients that will be treated with an effective therapy. Patients with moderate to severe RA treated with tocilizumab will be asked to complete the BRADA and ABILHAND questionnaires at screening, baseline, after 12 weeks and after 24 weeks of treatment. All other assessments and questionnaires from daily clinical practice (such as the global assessment of disease activity by the patient, the Health Assessment Questionnaire (HAQ), the SF36 questionnaire, measurement of ESR and CRP and the DAS 28 calculation), will also be used to evaluate these questionnaires.

Polymorphisms occur in several genes encoding key enzymes in the folate pathway may affect drug metabolism in patients with rheumatoid arthritis. Whether these genetic variations contribute to differential responses to antifolate drug in patients with rheumatoid arthritis (RA) remains to be investigated in the Taiwanese population. Objective. The goal of the present study is to investigate the interactions between genetic variations in folate genes and the efficacy/side effects of anti-folate disease-modifying antirheumatic drug in Taiwan. DESIGN. A cross-sectional study involving 100 patients with RA were enrolled from TCVGH. Genotypes in methylenetetrahydrofolate reductase (MTHFR677C>T), tandem repeat polymorphism in thymidylate synthase enhancer region (TSER) and folylpoly-gamma-glutamate synthetase (FPGS1901T>C) were determined by RFLP or pyrosequencing.

The purpose of this observational study was to observe and assess the long term use, safety, and effectiveness of adalimumab in a normal clinical setting.

The objective of the study is to identify and validate predictive markers of infliximab responsiveness in RA patients by 2 approaches: i) measuring biochemical, immunological and bone markers in sera because of their involvement in pathogenic mechanisms; ii) identifying gene-expression signatures in PBMCs by the transcriptomic analysis. Patients with active RA (ACR criteria) were given i.v. 3 mg/kg infliximab associated with metotrexate at weeks 0, 2, 6, and every 8th week. Infliximab efficacy was evaluated at week 14, using the EULAR response criteria. Just before the starting of infliximab treatment, the following parameters were measured in the sera: i) immunological tests: rheumatoid factor (IgA, IgG, IgM), anti-CCP, autoAb recognizing the 27 C-terminal fragment (ACAST-C27) and domain I (ACAST-DI) of calpastatin, anti-G6PI, anti a-enolase, anti-keratin and anti-perinuclear factor; ii) biochemical markers: CRP, MMP-1, MMP-3, TIMP-1, TIMP-2; markers of bone resorption: pyridinolin, deoxypyridinolin, osteoprotegerin, sRANKL, COMP. The predictive value of each parameter for a response/non-response to infliximab was analysed using Fischer's exact, Mann-Whitney and Chi2 tests. A blood sample was collected just before the onset of infliximab treatment and total RNAs were extracted from the peripheral blood mononuclear cells. The [33P] radiolabeled mRNAs were hybridized (duplicate or triplicate) over a set of 10.000 human cDNA probes spotted at a high density on nylon membranes. Data were normalized and filtered to allow the comparison between RNA samples. Statistical analyses were performed with the R software and hierarchical clustering was performed with the Cluster and Tree View softwares.

The special use-results surveillance is conducted in patients who have never been treated with Enbrel and in whom its long-term therapy may be instituted in the actual setting of use after marketing with the following objectives: 1. To examine the safety of long-term use of Enbrel including the occurrence of malignant tumors. 2. To confirm the efficacy of Enbrel in the long-term use.
