title: Use of biological agents in patients with moderate to severe psoriasis: a cohort-based perspective.
abstract: OBJECTIVE
  To compare characteristics of patients enrolled in a long-term multicenter cohort trial who had used biological therapies for treatment of psoriasis with those who had not used these agents.
  
  
  METHODS
  Retrospective analysis of users vs nonusers of biological therapies.
  
  
  METHODS
  Database from the PUVA Follow-up Study, a multicenter, 30-year study of patients originally treated with psoralen UV-A (PUVA) for moderate to severe psoriasis. Patients A total of 521 patients who completed the last cycle of follow-up of the PUVA Follow-up Study.
  
  
  METHODS
  Demographic data, severity data (physician global assessment), type of biological therapy used, patients' opinions about their therapy, and their best treatment.
  
  
  RESULTS
  Seventy-four of 521 patients (14%) used biological therapies: 65% etanercept (n = 48), 22% infliximab (n = 16), 11% efalizumab (n = 8), and 8% alefacept (n = 6). Users of biological therapies were younger, had more formal education, and were more likely to have had a greater extent of psoriasis at entry than the other cohort members. In 1998, those who used biological treatments were more likely than other cohort members to have been assessed as having severe psoriasis. In 2004, no significant difference was noted. Users of etanercept considered this agent to be as effective as methotrexate and more effective in clearing their skin and having fewer adverse effects than PUVA or UV-B. The proportion of patients originally enrolled in the 16 centers who had used biological agents varied greatly (0%-33%).
  
  
  CONCLUSIONS
  After short durations of therapy, patients' opinions about biological agents tended to be positive.
