Vitiligo is an acquired depigmentation disorder of great cosmetic importance, affecting 1% of the general population. Photochemotherapy is the most commonly used treatment modalityinextensivevitiligo,butisassociatedwithmanyshortand long-term side-effects. Recently, narrow-band ultraviolet B (NBUVB) therapy has been reported to be an effective and safe therapeutic option in patients with vitiligo. We studied the efficacy and safety of NBUVB (311 nm) therapy in Indian patients with generalized vitiligo. Methods. Fourteen patients (six males and eight females), aged 12- 56 years, with generalized vitiligo, were treated thrice weekly with NBUVB radiation therapy for a maximum period of 1 year. Results. At the end of 1 year, 10 patients (71.4% ) had marked to complete repigmentation and two each (14.3% ) had moderate or mild repigmentation. Repigmentation sites showed an excellent color match. The response to therapy was correlated with the sites of involvement, duration of disease, and compliance to therapy. Adverse events were limited and transient. Conclusion. NBUVB therapy is effective and safe in Indian patients with vitiligo. Long- term follow up is required, however, to establish the stability of repigmentation.展开更多

Treatment options in this age group are few and have disappointing response rates. This study was designed to evaluate the role of narrow-band UVB in the treatment of generalized vitiligo in children. Twenty-six children (aged 5-14 years) with generalized vitiligo (minimal extent of depigmentation of 5%oftheskin)were treated three times per week with narrow-band UVB therapy for a maximum period of 1 year. Of 26 patients, 6 were lost to follow up and 20 (7 males, 13 females) completed the study. At the end of 1 year of therapy, 15 (75%) patients developed marked to complete repigmentation. Moderate and mild repigmentation was noted in four (20%) and one (5%) patients, respectively. An average number of 34 (±2) treatment visits was required to achieve 50%repigmentation. Adverse events were mild and transient. Narrow-band UVB is an effective and well-tolerated treatment option for childhood vitiligo.展开更多

To study the clinical and epidemiological profile of vitiligo in the elderly, we retrospectively analyzed the data of patients with vitiligo having onset of disease after 50 years of age attending the pigmentary clinic of our center. Of the 182 patients, 87 (47.8% ) were males and 95 (52.2% ) were females. The mean age of onset of disease was 55± 2.3 years. Vitiligo vulgaris was the most common (83.5% ) followed by focal (5.5% ), segmental (4.4% ), acrofacial (3.8% ), mucosal (2.2% ), and universal (0.5% ). The most common site of onset was the head and neck (24.2% ) followed by the upper limbs (23% ), trunk (22% ), lower limbs (17.6% ), oral/genital mucosae (7.1% ), and flexures (6% ). Koebner’ s phenomenon was observed in 14.8% while leukotrichia was present in 47.3% of the patients. Halo nevi were observed in 3.8% of patients, and vitiligo was stable in 64.8% . Twenty- nine (15.9% ) patients had family history of vitiligo. Associated autoimmune autoimmune/endocrine disorders were present in 39 (21.4% ) of the patients. Differences in disease characteristics compared with vitiligo in children and young adults are discussed.展开更多

Considering the lack of uniformly effective and safe treatment modalities for children with vitiligo, search for newer therapeutic agents continues. This study was designed to evaluate the role of topical tacrolimus in the treatment of childhood vitili go. Twenty-five children with vitiligo were treated with topical 0.03%tacrolim us ointment applied twice daily for 12 weeks. Response was noted as marked to co mplete ( > 75%repigmentation), moderate (50-75%repigmentation) and mild ( < 5 0%repigmentation). Twenty-two children (9 boys and 13 girls) of mean age 7.2 ±1.4 years completed the study. Twelve (54.5%) children had vitiligo vulgaris, nine (40.9%) had focal vitiligo and one (4.5%) had segmental vitiligo. The me an duration of disease was 8 ±3 months. Nineteen (86.4%) children showed some repigmentation at the end of 3 months and other three had no response. Of these 19 children, repigmentation was markedtocompletein11(57.9%),moderateinfive(26.3 %)and mild in three (15.7%) children. Side effects were minimal, such as the p ruritus and burning noted in only three patients. Topical tacrolimus is an effec tive and well-tolerated treatment modality in Asian children with vitiligo.展开更多
