    Abstract:
    INTRODUCTION: A wide range of treatments are available for psoriasis, including pharmaceuticals and phototherapy. Calcipotriol/betamethasone dipropionate and narrow-band ultraviolet phototherapy (NB-UVB) are both effective monotherapies for psoriasis; however, these two therapies have never been directly compared in a prospective clinical study. In this study, we compared the efficacy of combined calcipotriol/betamethasone dipropionate to NB-UVB in psoriatic patients with Psoriasis Area Severity Index (PASI) 9-10 treated in a routine clinical practice. PATIENTS AND METHODS: This prospective, observational study included 58 consecutive patients (age range, 19-65 years) diagnosed with recurrent chronic small plaque psoriasis. Patients were offered either topical therapy with a two-compound ointment containing calcipotriol (50 μm/g) and betamethasone dipropionate (0.5 mg/g) or NB-UVB (311 nm). Disease severity was assessed at baseline and posttreatment according to PASI and target lesion score (TLS) and by high-frequency (20 MHz) ultrasonography (HF-USG). RESULTS: No statistically significant difference between the groups was observed in baseline or posttreatment PASI scores. Both treatments resulted in substantial reductions in PASI: 85% and 82%, respectively, for the calcipotriol/betamethasone group and the NB-UVB group. Both treatments significantly decreased the subepidermal low echogenic band (SLEB) thickness, with no significant differences between the two groups in terms of the percentage reduction in SLEB. CONCLUSIONS: This study demonstrates, for the first time, that NB-UVB phototherapy and fixed combination calcipotriol/betamethasone ointment are equally effective in treating plaque psoriasis in patients with PASI 9-10 in routine clinical practice. In addition, measurement of SLEB thickness with HF-USG may be a useful objective parameter to assess skin lesions.
