Abstract:
Objective To compare the efficacy and safety of excimer laser 308 nm phototherapy alone and the combination of excimer laser 308 nm and topical application of vitamine D3 alanogue tacalcitol in the treatment of vitiligo. Methods Seventy-eight patients with vitiligo were enrolled in the single-blind clinical trial, treated with excimer laser 308 nm. The lesions were devided into two groups: patients in the experimental group were instructed to use tacalcitol ointment and the control group were applied with placebo ointment. The lesions were evaluated once per month and photos taken for analyses of clinical effects. Results The results in different locations were compared, the effective rates of the experimental group in cephalofacial site, trunk and limbs were 93.51%, 84.16 % and 42.35 %, respectively. The effective rates of control group in opposite and adjacent sites were 90.9 %, 77.45 % and 34.15 %, respectively (P ＜ 0.05). The comparison of results in different types of lesions indicated that the effective rate of the experimental group in vitiligo vulgaris and segmental vitiligo were 73.81% and 84.00 %, respectively. The effective rate of control group in vulgaris and segmental vitiligo were 86.8 %, 77.45 % and 34.15 %, respectively (P ＜0.05 ). The comparison of results in radiation times and doses of phototherapy showed that the radiation time and dose on the time of initial pigment regeneration were (16. 15 ± 3.22)times and (4.40 ± 5.03)J/cm2 in the experimental group, while ( 18.56 ± 3.50) times and ( 6.60 ± 1.01 ) J/cm2 ( P ＜ 0.05 ) in the control group, the time and dose on the time of apparent effect were ( 20. 36 ± 1.50 ) times and ( 7.50 ± 3.54 ) J/cm2 in the experimental group, and (21.68 ± 2.40) times and( 8.80 ± 9.24)J/cm2 (P ＜ 0.05 ) in the control group. Conclusion Application of tacalcitol ointment in combination with twice-weekly 308 nm excimer laser light phototherapy is an effective alternative treatment for patients with generalized vitiligo.
