However, there seems to be little clinical effect of vitamin D3 without UV exposure. In the present study, we evaluated the clinical difference of sun irradiation vs. narrowband UVB in combination with tacalcitol assessing the change of lesion size and color tone by a spectrophotometer. Thirty-three vitiligo patients were composed of 19 treated with sun illumination and 14 treated with narrowband UVB in combination with topical use of tacalcitol. The mean % size reduction was higher in the group of sunbathing than narrowband UVB (29% vs. 23%). Delta L score, which represented the difference of whiteness between lesional and perilesional skin, was significantly improved after treatment in the group of sun irradiation instead of narrowband UVB (p = 0.0023). Therefore, we consider that sun illumination along with tacalcitol may be able to induce natural repigmentation and be an alternative therapeutic option for vitiligo vulgaris.展开更多

Objective: To compare the efficacy and safety of treatment with the two-compound product for 4 weeks followed by calcipotriol for 4 weeks, with that of tacalcitol for 8 weeks in patients with stable psoriasis vulgaris. Methods: 501 patients were randomised to double-blind treatment with the two-compound product followed by calcipotriol 50 μg/g once daily, or to tacalcitol 4 μg/g once daily. Results: Treatment with the two-compound product/calcipotriol was significantly more effective than tacalcitol in terms of mean percentage PASI reduction (65.0 vs. 33.3%at week 4 and 59.0 vs. 38.4%at week 8; P < 0.001 for both). Conclusion: A treatment regimen comprising calcipotriol/betamethasone ointment (Daivobet) for 4 weeks followed by calcipotriol for 4 weeks is superior to tacalcitol ointment for 8 weeks in patients with psoriasis vulgaris.展开更多
