摘要 Background: Combining phototherapy with topical and oral agents allows clinicians to treat recalcitrant psoriasis with reduced number of treatments and cumulative UV exposures. Objective: This study was designed to determine the number of treatments necessary to clear plaque-type psoriasis when narrowband (NB) UVB is administered with methotrexate (MTX) or placebo in a randomized, controlled fashion. Methods: MTX (15 mg/wk) or placebo was administered 3 weeks before standard NB UVB phototherapy was started. Treatments with the oral agent and phototherapy were continued until Psoriasis Area and Severity Index scores were reduced to less than 10% of the original scores or 24 weeks. Followup was performed until lesional scores returned to 50% of the original ones. Results: A total of 24 patients were enrolled and 19 patients completed the study. Kaplan-Meier analysis revealed that the median time to clear psoriasis in the MTX/NB UVB group was 4 weeks, which was significantly less than that for the placebo/NB UVB group. Limitations: Our sample size was relatively small (24 patients) with 5 dropouts. In addition, the study was conducted in skin types III to IV, Asian patients. Follow-up was limited to 4 to 6 months after completion of phototherapy. Conclusion: MTX pretreatment allows physicians to clear psoriasis in fewer phototherapy sessions than when phototherapy is administered alone.
