A Randomized Comparison of Acitretin-narrow-band TL-01 Phototherapy and Acitretin-Psoralen plus Ultraviolet A for Psoriasis

Abstract

The combination of retinoids with phototherapy enhances the efficacy of phototherapy and reduces the cumulative ultraviolet dose and duration of the therapy needed to treat chronic plaque psoriasis. Although TL-01 phototherapy has been used widely, there are few data about the effectiveness of the combination of acitretin with TL-01 in treatment of the disease. The aim of this study was to compare acitretin-narrow-band TL-01 phototherapy with acitretin-psoralen plus ultraviolet A (acitretin-PUVA) in psoriasis. We studied 60 patients with moderate to severe plaque psoriasis who were randomly allocated to three times weekly treatment acitretin-narrow-band TL-01 or acitretin-PUVA. The efficacy of treatments was assessed using the Psoriasis Area and Severity Index by a blinded observer. Clearance of psoriasis was achieved in 56.6% of patients treated with acitretin-narrow-band TL-01 and in 63.3% of those treated with acitretin-PUVA. All of these patients remained clear of psoriasis 3 months after finishing the treatments. Mucocutaneous side-effects, such as dry lips and mouth, were the most common complaints in both groups. In conclusion, acitretin-narrow-band TL-01 is an effective and well-tolerated treatment for moderate to severe plaque psoriasis, with a therapeutic effect equal to that of acitretin-PUVA.
