title: Effectiveness and safety of psoralen-UVA (PUVA) topical therapy in palmoplantar psoriasis: a report on 48 patients.
abstract: BACKGROUND
  Palmoplantar psoriasis is an uncommon clinical form of psoriasis. Although localized to the palms and soles, it has a considerable impact on the patient's function and quality of life.
  
  
  OBJECTIVE
  To study the effectiveness and safety of psoralen-UV-A (PUVA) therapy in palmoplantar psoriasis and investigate predictors of clinical response.
  
  
  METHODS
  We performed a retrospective chart review of all patients with palmoplantar psoriasis treated with topical PUVA therapy at our hospital between 2008 and 2011. Data were collected on effectiveness (using physician global assessment [PGA] scores), safety, and a range of clinical, epidemiological, and treatment-related variables.
  
  
  RESULTS
  We studied 48 patients (33 women and 15 men) with a mean age of 51 years. Treatment was considered to be effective (PGA score of 0 or 1) in 63% of cases. In addition to PUVA, systemic therapy was required in 47.9% of patients; the drug most often used was acitretin. Adverse effects were reported for 25% of patients during treatment. The most common effect was mild erythema, present in 18% of cases.
  
  
  CONCLUSIONS
  In our experience, topical PUVA is an appropriate treatment alternative for palmoplantar psoriasis; it offers similar response rates to systemic treatments, but has a better tolerance and safety profile. Associated systemic treatment, with acitretin in most cases, improved the probability of a satisfactory response to PUVA and should be considered in patients who do not respond adequately after 8 to 10 sessions.
