| dc.description.abstract | Background: Psoriasis is a common chronic disease. It is estimated that between US$1.6 billion and US$3.2 billion is spent per year to treat psoriasis. Objective: To compare psoralen plus UV-A (PUVA) therapy with topical steroids in moderate plaque psoriasis. Methods: In this randomized, clinical trial with cost analysis, 88 patients with moderate plaque psoriasis were recruited in two equal groups to receive either PUVA therapy or topical steroids. The induction phase was applied for 4 months and the patients were followed-up for another 3 months, while the maintenance therapy continued. Outcome, direct cost (related to medications, phototherapy, laboratory tests, and medical consultation), indirect cost (related to transportation and other extra expenditures) and total cost (direct plus indirect costs) were compared between the two groups. Results: The outcome was equally satisfactory in both groups. The indirect cost was significantly higher in the PUVA group, while the direct and total costs as well as the patients' satisfaction rate were comparable. Recurrence was significantly more frequent in the topical group. Conclusion: Although both PUVA therapy and topical steroids are equally efficient and cost-effective in moderate plaque psoriasis, the recurrence rate is higher in the latter group. | |
