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.
To evaluate efficacy, safety and pharmacokinetics of adalimumab in Japanese children with Polyarticular Juvenile Rheumatoid Arthritis
To study Celebrex versus naproxen to see if it decreases symptoms of juvenile arthritis such as pain and swelling.
This study will evaluate the efficacy and safety of RoActemra/Actemra (tocilizumab) in patients with active systemic juvenile idiopathic arthritis (sJIA) who have an inadequate clinical response to NSAIDs and corticosteroids. In Part I of the study patients will be randomized 2:1 to receive iv infusions of RoActemra/Actemra (8mg/kg iv for patients >=30kg, or 12mg/kg for patients <30kg) or placebo, every 2 weeks. Stable NSAIDs and methotrexate will be continued throughout. After 12 weeks of double-blind treatment, all patients will have the option to enter Part II of the study to receive open-label treatment with RoActemra/Actemra for a further 92 weeks, followed by a 3-year continuation of the study in Part III in which, for patients who meet specific criteria, an optional alternative dosing schedule decreasing the study drug administration frequency will be introduced. Anticipated time on study treatment is up to 5 years.
The purpose of this research study is to see if patients with juvenile idiopathic arthritis or seronegative arthritis (and related conditions) mount protective immune responses to the human papillomavirus (HPV) vaccine called Gardasil. The researchers also want to monitor for any increase in disease activity following receipt of the vaccine.
2000 international units (IU) vitamin D, 1 gram (gm) calcium, or both given to children with Juvenile Rheumatoid Arthritis (JRA) may increase percent true calcium absorption, bone mineral turnover and/or bone mineralization.
This study has the following objectives: Primary objective: - To determine the safety and tolerability of oral ITF2357 in patients with active SOJIA with inadequate response or intolerance to standard therapy with oral steroids and methotrexate, with or without previously used biologic agents. Secondary objectives: - to evaluate the effect of ITF2357 on disease activity in patients with active SOJIA - to investigate the possibility of steroid dose tapering in patients with active SOJIA during ITF2357 treatment - to assess the effect of ITF2357 on levels of circulating cytokines - to assess the pharmacokinetic properties of ITF2357
Systemic juvenile idiopathic arthritis (SJIA) is a type of arthritis that typically occurs before 16 years of age. SJIA usually involves heat, pain, swelling, and stiffness in the body's joints. It can also involve fever, rash, anemia, and inflammation in various parts of the body. Rilonacept is a drug that can reduce inflammation. The purpose of this study is to determine whether a rilonacept drug regimen initiated early is more effective than a similar rilonacept drug regimen initiated 4 weeks later when treating children and young adults with SJIA.
Prospective, multi-center clinical study to evaluate the clinical outcomes of the posterior stabilized design of the LCS® Complete Mobile-bearing Total Knee System
This postmarketing surveillance study will evaluate the safety profile of Enbrel (etanercept) in an Indian population. It will provide surveillance on a currently approved indication for Enbrel of reducing symptoms and inhibiting the progression of structural damage in patients with moderately to severely active rheumatoid arthritis.
