BACKGROUND: The addition of calcipotriol ointment to PUVA therapy for psoriasis vulgaris results in a lower total UVA dose and a faster onset of response. The addition of calcipotriol cream to PUVA, however, has not been studied. OBJECTIVE: To investigate whether combining calcipotriol cream with PUVA therapy has a UVA sparing effect. METHODS: We performed a randomized, multicentre, vehicle-controlled, double-blind, 12-week comparative study including 120 patients with psoriasis covering 20-50% body surface area. The study consisted of a washout phase followed by a 10-week treatment phase. PUVA therapy three times weekly was added within 1 week after randomization. Efficacy was assessed by the Psoriasis Area and Severity Index (PASI). RESULTS: At baseline the mean PASI scores were 17.5 and 19.2 in the calcipotriol and vehicle (placebo) groups, respectively. At the end of treatment, the mean PASI scores were 2.65 and 7.03 (p<0.01), respectively. A reduction in PASI score >90% was observed in 69% of the patients in the calcipotriol-treated group and in 36.4% of the patients in the vehicle group (p<0.01). CONCLUSION:Calcipotriol cream plus PUVA clearly reduces the cumulative dose of UVA and improves the response of psoriasis vulgaris to PUVA.
