Juvenile Idiopathic Arthritis
Conditions
Brief summary
The aim of our study is to compare the immune function of patient treated with DMARD (methotrexate), or tumor necrosis factor (TNF)-alpha inhibitor (adalimumab) to healthy children. The study consists of three parts. In each part physical examination and routine laboratory tests are done. At the first examination flow cytometry analysis is performed, after that the participants are immunized with influenza (3Fluart) vaccine. At part two and three further flow cytometry is carried out and seroconversion is measured.
Interventions
Comparing immune function and seroconversion after immunizing healthy children and juvenile idiopathic arthritis (JIA) children treated with different type of medication with influenza vaccine.
