Tocilizumab in the treatment of systemic juvenile idiopathic arthritis
نویسندگان
چکیده
Systemic juvenile idiopathic arthritis is one of the common rheumatic diseases in childhood and characterized by spiking fever, evanescent skin rash, lymphadenopathy, hepatosplenomegaly, and serositis, in addition to arthritis. Children with systemic juvenile idiopathic arthritis often show growth retardation and developmental abnormality, as well as macrophage activation syndrome, a life-threatening complication. Overproduction of interleukin-6 is pathologically responsible for the systemic inflammatory manifestations and abnormal laboratory results with systemic juvenile idiopathic arthritis. Thus, tocilizumab, a humanized antihuman interleukin-6 receptor antibody, has been developed as a therapeutic agent for the disease. A series of clinical studies have demonstrated the excellent efficacy and safety of tocilizumab for patients with active disease. Tocilizumab was approved for systemic juvenile idiopathic arthritis in Japan in 2008 and in the European Union and the United States in 2011.

With the recent approval of tocilizumab as the first biologic for the treatment of systemic juvenile idiopathic arthritis (sJIA), an important unmet medical need for this historically challenging disease has now been met. The purpose of this review article is to revisit the established therapeutic options for sJIA, to summarize the history of the clinical trials with tocilizumab, and to discuss...
متن کاملThe correlations of serum interleukin-6 (il-6) levels and serum soluble il-6 receptor levels with disease activity in systemic juvenile idiopathic arthritis patients with and without tocilizumab treatment
Introduction Interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) have been demonstrated to play a significant role as inflammatory mediators in systemic juvenile idiopathic arthritis (SJIA). Tocilizumab, a humanized anti-IL-6 receptor antibody, becomes a new biologic treatment for SJIA nowadays but the correlation of serum IL-6 levels and serum sIL-6R levels with disease activity in SJIA wi...
متن کاملTocilizumab (TCZ) may be an effective treatment for poly-juvenile idiopathic arthritis (pJIA) as for rheumatoid arthritis (RA)
Purpose TNF inhibitors are established treatment for poly-juvenile idiopathic arthritis (pJIA), but there are needs of alternative therapy for refractory patients. Tocilizumab (TCZ) has been widely used for rheumatoid arthritis (RA) in adults, and the effectiveness for systemic JIA has been well-documented. However, the experience on pJIA is limited. We compared the clinical courses of our pati...
متن کاملMacrophage activation syndrome in patients with systemic juvenile idiopathic arthritis treated with tocilizumab
Introduction Macrophage activation syndrome (MAS) is a severe, potentially fatal complication of systemic juvenile idiopathic arthritis (sJIA). Changes in therapies, including biologics, have been associated with the onset of MAS. Interleukin-6 (IL-6) plays a major pathogenic role in sJIA; data in animals suggest that high IL-6 levels contribute to the triggering of MAS [1]. Treatment with the ...

Tocilizumab (TCZ) is the first FDA- approved treatment for systemic juvenile idiopathic arthritis (sJIA). We report 3 cases of cytopenias in children with sJIA treated with TCZ. Two of the children who developed significant cytopenias shortly after initiation of TCZ had a history of macrophage activation syndrome. We raise the possibility that patients with a tendency towards MAS have an increa...
