title: Efficacy of etanercept in psoriatic patients previously treated with infliximab.
abstract: BACKGROUND
  There are few data to enable us to ascertain whether switching to another systemic agent is useful in patients with psoriasis who have not responded favorably to a first systemic treatment.
  
  
  OBJECTIVE
  To evaluate the efficacy and safety of etanercept in patients with moderate-to-severe plaque psoriasis previously treated with infliximab.
  
  
  METHODS
  We analyzed data from patients with moderate-to-severe psoriasis and a poor primary or secondary response to infliximab, and who were later treated with etanercept.
  
  
  RESULTS
  Data were collected from 8 patients who were first treated with infliximab. At 54 weeks of therapy, 25% had a psoriasis area and severity index (PASI) of 75. At 24 weeks of therapy with etanercept, 75% had a PASI of 75. Consecutive administration of both therapies did not increase the number of adverse events.
  
  
  CONCLUSIONS
  The data should be regarded with caution due to the scant number of patients.
  
  
  CONCLUSIONS
  Switching from infliximab to etanercept can be useful and safe in nonresponders.
