title: Abatacept for severe anti-tumor necrosis factor alpha refractory juvenile idiopathic arthritis-related uveitis.
abstract: OBJECTIVE
  To evaluate the safety and efficacy of abatacept in patients with severe juvenile idiopathic arthritis (JIA)-related uveitis refractory or intolerant to immunosuppressive and anti-tumor necrosis factor alpha (anti-TNFalpha) agents.
  
  
  METHODS
  Patients with JIA-related uveitis refractory to immunosuppressive and anti-TNFalpha agents were treated with intravenous abatacept (10 mg/kg monthly). Side effects, frequency of uveitis flares, and ocular complications before and after treatment were reported.
  
  
  RESULTS
  Seven patients (6 females and 1 male) with a mean uveitis duration of 11.6 years entered the study. All patients had failed previous immunosuppressive therapy and >or=2 anti-TNFalpha treatments. All patients responded to abatacept and 6 maintained a clinical remission after a mean of 9.2 months of treatment. One patient withdrew from the study with oral mycosis and arthritis flare; no other patients had side effects. The mean frequency of uveitis flares during the 6 months before and after treatment decreased from 3.7 to 0.7 episodes. No new ocular complications or worsening of preexisting ones were reported.
  
  
  CONCLUSIONS
  Abatacept treatment led to sustained improvement in severe anti-TNFalpha-resistant JIA-related uveitis and was well tolerated in all but 1 patient. These results provide new insights into a possible indication of abatacept for the treatment of uveitis.
