Abstract

The results of efficacy and safety study of abatacept and methotrexate combination therapy (n=12) in comparison with methotrexate monotherapy (n =41) in patients with polyarticular juvenile idiopathic arthritis at the age of 4–17 years old are shown in this article. The duration of the observation was 1 year. Abatacept was introduced at a dose of 10 mg/kg at 1st, 2d and then — every 4th week.
