An Open-label, Multi-arm, Non-comparative Safety and Tolerability Study of Canakinumab (ACZ885)...
Systemic Juvenile Idiopathic ArthritisThis two-part open-label, multi-arm, non-comparative study will collect long-term safety, efficacy and tolerability data from patients who were responsive to canakinumab from study CACZ885G2301E1 (Cohort 1), and from patients who are treatment naïve to canakinumab (Cohort 2). In addition, the effect of inactivated vaccines in an SJIA patient population will be assessed for the development of adequate (protective) antibody levels following immunization according to respective local vaccination guidelines. Study Part I: All patients will be treated with canakinumab 4 mg/kg every 4 weeks (or 2 mg/kg every 4 weeks for Cohort 1 patients who are receiving that dose in CACZ885G2301E1) until study end unless discontinuation occurs, or until they qualify for Part II of the study. Study Part II: Patients who are eligible will be randomized to receive canakinumab at a reduced dose or prolonged dose interval (see requirements for dose reduction/dose interval prolongation below). Patients in Cohort 1 receiving 2 mg/kg q4wk in CACZ885G2301E1 will not be randomized but will be part of the treatment arm canakinumab dose reduction if they are eligible.
Sarcopenia in Children
SarcopeniaJuvenile Idiopathic ArthritisJuvenile idiopathic arthritis (AJI), is a frequent inflammatory disease in children, characterized by pain, arthritis, and deformities. Chronic inflammation leads to physical inactivity and can be associated with muscle weakness around affected joints, low bone strength, and mass(3). To our knowledge, no study has focused on the prevalence of sarcopenia in JIA and the data on the muscle disorder are lacking. The purpose of the present study is to detect sarcopenia and identify associated factors in children with JIA
Fibrinogen to Albumin Ratio and C-reactive Protein to Albumin Ratio in Juvenile Idiopathic Arthritis...
Juvenile Idiopathic ArthritisThe fibrinogen to albumin ratio (FAR) and C-reactive protein to albumin ratio (CAR) have emerged as useful biomarkers to predict systemic inflammation. The aim here is to investigate the relation between FAR/CAR and Juvenile arthritis disease activity score (JASDAS27) in Juvenile idiopathic arthritis (JIA)
OHRQoL Evaluation After Functional Therapy in JIA Patients
Juvenile Idiopathic ArthritisThe aim of the study was to determine the changes in Oral Health-Related Quality of Life (OHRQoL) in patients with juvenile idiopathic arthritis (JIA) and temporomandibular joint (TMJ) disorders who underwent functional therapy for 24 months to assess the age and sex group in which the functional therapy was most effective.
Comparison of PK and Tolerability of MSB11022 Administered by AI or PFS
Rheumatoid ArthritisPolyarticular Juvenile Idiopathic Arthritis9 moreThe primary objective of this study is to demonstrate equivalence of the pharmacokinetic (PK) profile of MSB11022 administered by either an auto-injector (AI) or a pre-filled syringe (PFS) as single subcutaneous (s.c.) injection of 40 mg.
Using Self-evaluation to Increase Visit Intervals in Juvenile Idiopathic Arthritis
JIASelf-EvaluationIn the THUIS study, JIA patients in clinical remission will skip one 3-monthly hospital control visit and instead monitor their disease activity at home. Outcomes at 6 months will be compared to those from a historical cohort.
Exercise and Body Composition in Juvenile Idiopathic Arthritis
ArthritisJuvenileThis research is being done to see if resistance exercise (RE) is safe and has a positive effect on children and young adults with juvenile idiopathic arthritis (JIA). JIA is an inflammatory autoimmune disease that can cause severe impairment and disability. JIA can cause bone loss and decreased muscle strength. The medications used to treat JIA can also have negative effects on growth and development, strength, and ability to function. RE is performing movements in a slow and controlled fashion (i.e., no speeding up or using force in the lifting and lowering of the weight) to lessen force on the joints and tissues. This study will be using Ren-Ex exercise equipment to perform RE. Currently the American College of Rheumatology recommends exercise for patients with arthritis. This exercise includes range of motion exercise to protect joint mobility as well as low resistance and aerobic exercise (AE) to protect muscle mass, bone health, and fitness. However, a recent study showed no major differences in functionality or quality of life between patients who performed AE and those who did not perform AE. There is a need for more data on the impact of RE on children with JIA. Children and young adults aged 10 to 21 with juvenile idiopathic arthritis may join.
Safety and Efficacy of Measles, Mumps, Rubella Vaccination in Juvenile Idiopathic Arthritis
ArthritisJuvenile RheumatoidBackground: 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.
