title: Biologics in children's autoimmune disorders: efficacy and safety.
abstract: Advances in understanding the pathogenesis of rheumatic diseases have led to the discovery of mechanisms of inflammation and autoimmunity and have made possible the invention of new target-specific drugs. Biologic drugs, designed to inhibit specific components of the immune system, such as cytokines, cytokine gene expression, and their complex interactions, have revolutionized the treatment options in pediatric rheumatology. Only three agents are currently available for treating juvenile idiopathic arthritis (JIA): etanercept, at the dose of 0.8 mg/kg once weekly, adalimumab at the dose of 24 mg/m(2) every 2 weeks, and abatacept at the dose of 10 mg/kg at weeks 0, 2, 4, and then every 4 weeks. They are well tolerated and relatively safe in children: Side effects are generally mild and include injection site reactions and infections. Infliximab, rilonacept, and canakinumab are also approved by the Food and Drug Administration for treatment of pediatric autoimmune disorders and are currently investigated in JIA. This review summarizes the current state of biologic drugs, their clinical application, and their efficacy and safety in the pediatric age.
