title: Adalimumab for severe psoriasis and psoriatic arthritis: an open-label study in 30 patients previously treated with other biologics.
abstract: BACKGROUND
  Psoriasis is a chronic, genetically determined, immune-mediated, inflammatory skin disease affecting approximately 2% to 3% of the Caucasian population. Previously reported data demonstrated adalimumab to be an efficacious treatment of psoriatic arthritis and plaque-type psoriasis. Adalimumab is a fully human monoclonal antibody IgG1 against tumor necrosis factor alpha.
  
  
  OBJECTIVE
  To evaluate the efficacy and safety of adalimumab, in the treatment of psoriasis patients whose disease is refractory to treatment with other biologic agents.
  
  
  METHODS
  Thirty patients affected by plaque-type psoriasis with or without psoriatic arthritis, unresponsive to conventional and biologic systemic treatments were enrolled. Adalimumab was administered in monotherapy, at a dosage of 40 mg, subcutaneously, once a week.
  
  
  RESULTS
  At week 12, 26 of 30 patients (87%) achieved Psoriasis Area and Severity Index (PASI) 75; at week 24, 25 of 30 patients (83%) achieved PASI 75. Concerning psoriatic arthritis, at week 24, the mean Health Assessment Questionnaire score improved from 0.99 to 0.2, Ritchie articular index from 10.15 to 2, and Pain Visual Assessment Score from 6.32 to 1.2. Furthermore, therapy with adalimumab considerably enhanced patients' quality of life as assessed by two measures (Dermatology Life Quality Index, Psoriasis Disability Index). Adalimumab was generally safe and well tolerated.
  
  
  CONCLUSIONS
  This is not a randomized placebo-controlled study and is restricted to a small number of patients.
  
  
  CONCLUSIONS
  In our experience, although preliminary, monotherapy with adalimumab 40 mg weekly proved to be an effective and safe treatment for the management of plaque-type psoriasis and psoriatic arthritis, with a rapid onset of action in patients whose disease had been refractory to both conventional and biologic agents.
