Abstract

Uveitis is one of the most serious manifestations of Juvenile Idiopathic Arthritis (JIA), with the potential to cause severe sight-threatening ocular complications. The first line treatment consists of topical and oral steroids with DMARDs therapy for more severe cases, including immunosuppressive and anti-TNFα agents. Abatacept (CTLA-4 immunoglobulin) is a soluble, fully human fusion protein that consists of the extracellular domain of CTLA-4, linked to a modified Fc portion of the human immunoglobulin IgG1, which does not activate the complement. The drug is approved for the treatment of polyarticular JIA.

Highlights

  • Uveitis is one of the most serious manifestations of Juvenile Idiopathic Arthritis (JIA), with the potential to cause severe sight-threatening ocular complications

  • We evaluated the efficacy and safety of Abatacept in a series of young patients with sight-threatening JIArelated and idiopathic uveitis refractory to previous antiTNFa agents

  • We performed a monocenter collection of data of 12 patients affected by uveitis (10 JIA-related and 2 idiopathic) which resulted refractory to both classic immunosuppressive and anti-TNFa treatments and who started a therapy with Abatacept at a monthly dosage of 10 mg/kg, administered intravenously
