B-Zell-gerichtete Therapien bei Kindern und Jugendlichen mit rheumatischen Erkrankungen

摘要

The introduction of cytokine-targeted therapies has significantly improved the treatment options of rheumatic diseases; however, some patients are also refractory to these treatment measures. The B cells play a central role in the pathogenesis of many rheumatic diseases and B-cell targeted therapies are a promising option as second-line medication for treating patients with a refractory disease course. Randomized controlled trials analyzing the efficacy of B-cell directed therapies for childhood rheumatic diseases have not yet been performed. The use of the B-cell depleting antibody rituximab showed positive results in non-controlled case series of juvenile systemic lupus erythematosus (SLE) patients. Patients with a refractory disease course of oligoarticular or polyarticular juvenile idiopathic arthritis might also benefit from B-cell depletion using rituximab. The B cell-targeting therapies for the treatment of childhood rheumatic diseases should be initiated and closely supervised by a pediatric rheumatologist.
