Filter by:Background: The safety of vaccination in patients with autoimmune diseases using immune suppressive therapy is often discussed. Previous studies in Juvenile Idiopathic Arthritis (JIA) patients showed no increase in disease activity after immunisation with dead vaccines. The safety of the live attenuated Measles, Mumps, Rubella (MMR) vaccination was assessed retrospectively in JIA patients and no increase in disease activity was found. However, this must be prospectively confirmed. In addition, it is unknown whether vaccination is effective, since the immune response to vaccination may be diminished due to immunosuppressive therapy for the underlying disease. Finally, the influence of MMR vaccination on the immune system of JIA patients has not been studied. Among others, regulatory T-cells (Tregs) should control the immune response and prevent destructive autoimmune responses after environmental triggers such as vaccination. Objective: The aim of the present study is to investigate the safety and efficacy of the MMR booster vaccination and its influence on immune regulatory mechanisms in children with Juvenile Idiopathic Arthritis. Method: JIA patients aged 4 to 8 years and treated by the pediatric rheumatology units from various University Medical Centers in the Netherlands, are asked to participate in a prospective study. In the Netherlands, measles-mumps-rubella (MMR) vaccination is included in the National Vaccination Program and is normally administered at age 9. Included patients will be randomised for early vaccination (age group 4 to 8yr at entry of the study) or at age 9 as is routinely done according to the National Vaccination Program. Prior to and after vaccination the investigators will assess disease activity and collect blood. Outcome: During a 12 month follow-up period the investigators will register disease activity and side-effects at different moments in time to determine safety of vaccination. The efficacy of the vaccine will be studied according to antibody levels and function against measles, mumps and rubella in the blood. Tregs will be isolated and their functionality will be determined using the blood cells collected during follow-up. This enables us to study the role influence of vaccination on regulatory mechanisms in our immune system.
This is a Phase 1 study, involving a 29-day treatment period, designed to evaluate the pharmacokinetics and the effectiveness of investigational study drug ARRY-371797 in treating rheumatoid arthritis in patients receiving stable doses of methotrexate, and to further evaluate the drug's safety. Approximately 30 patients from the US will be enrolled in this study.
The purpose of this study is to evaluate the safety and effectiveness of golimumab in patients with active rheumatoid arthritis despite Methotrexate therapy. Another objective is to evaluate the pharmacokinetics of golimumab.
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.
This is a prospective, open-label, 1-arm, multicenter observational study to determine the average Remicade dosage and time span between 9 infusions in subjects with rheumatoid arthritis (RA)
This is a prospective, open-label, 1-arm, multicenter observational study to determine the dose and time interval of Remicade (Infliximab) infusions in psoriatic arthritis (PsA).
This 14-week study will observe the gene expression of certain immune cells in patients with rheumatoid arthritis who receive etanercept, infliximab, and adalimumab. Patients at the National Institute of Rheumatology and Physiotherapy, Budapest, who are already scheduled to receive an anti-TNF agent will be asked to participate in this study. Patients will receive their treatment (etanercept, infliximab, or adalimumab) as scheduled, and have blood samples collected during the study and analyzed by the laboratory. Patient's response to their treatment will also be studied based on x-rays and other examinations.
This study will gather information on the safety and efficacy of patients with rheumatoid arthritis (RA) who are starting treatment with infliximab for the first time. Patients will be treated in the usual manner according to local guidelines and normal clinical practice.
The primary objective of this study is to evaluate the performance of the Cormet Hip Resurfacing implant system in the post-approval environment.
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.
