Abstract
Objective: The purpose of this study is to compare the efficacy of three therapies in the treatment of non-segmental vitiligo: a combination of topical calcipotriol, narrowband-ultraviolet B (NB-UVB), and betamethasone therapies; a combination of NB-UVB and topical calcipotriol; and NB-UVB alone. Material and methods: Forty-five patients with non-segmental vitiligo presenting to our Dermatology clinic were recruited to participate in the study. Patients were randomly divided into three groups. For each patient the size of the depigmented areas was assessed according to the rule of nines. The first group was treated with a combination of topical calcipotriol, NB-UVB, and betamethasone therapies. The second group was treated with a combination of NB-UVB and topical calcipotriol and third group was treated with NB-UVB alone. Since the patients' vitiligo lesions had similar phototypes, all patients were started with 0.1 j/cm2, regardless of their skin phototype. The dose of NB-UVB was increased 10% in each session and no further increment was done after reaching 2.5 j/cm2. Treatment effectiveness was evaluated according to the percentage improvement in repigmentation. The quality of life of the patients was measured by the Dermatology Life Quality Index (DLQI). Results: The patients were aged from 13 to 55 years (mean: 25.29). The duration of disease ranged from 3 months to 20 years. Family history was positive for vitiligo in 10 patients (22.2%). The percentage of recovery after treatment was 63.33% ± 7.55 in group 1, 60.67% ± 5.75 in group 2, and 46.67% ± 7.98 in group 3. There was no statistically significant difference between groups 1 and 2, and groups 2 and 3, but there was a statistically significant difference between groups 1 and 3 (p = 0.0048). Conclusions: In conclusion, NB-UVB-alone therapy and the combined therapies are effective treatment options in the treatment of vitiligo. Future studies with larger groups are warranted to confirm our results.
