Novel therapies for the treatment of juvenile rheumatoid arthritis (juvenile idiopathic arthritis).

The majority of children with juvenile idiopathic arthritis respond well to conventional treatment. However, some children will have a more aggressive disease course and will be resistant to standard management. Over the past 20 years, growth in our understanding of the immunopathogenesis of juvenile idiopathic arthritis and related diseases has facilitated significant therapeutic advances. In this report, recently released antirheumatic drugs, as well as some treatments currently in development, will be discussed. Biological agents, such as antiTNF and other cytokines inhibitors, and unique drugs, such as thalidomide, provide new opportunities to suppress the inflammation found in severe cases of systemic onset juvenile idiopathic arthritis and can obtain a satisfactory outcome.
