Vitiligo usually begins in childhood with approximately half of the patients manifesting onset of disease prior to the age of 20 years. 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% of the skin) 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.
Various epidemiologic factors and clinical patterns of atopic dermatitis (AD) were evaluated in 672 children. Of these, 210 were infants (up to 1 year) and 462 were children. Mean age at onset and mean duration of the disease were 4.2 months and 3.3 months, respectively, in the "infantile AD" group. In the "childhood AD" group the corresponding figures were 4.1 years and 1.9 years. In both groups, patients from urban areas significantly outnumbered those from rural backgrounds. In the infantile AD group, the disease was aggravated in winter in 67.14%, in summer in 23.36% and in spring in 9.51% of patients. The corresponding figures in the childhood AD group were 58% in winter, 32.92% in summer, 7.43% in spring, and 1.74% in the rainy season. In the infantile AD group, personal and family history of atopy were seen in 0.91% and 36.19% of patients, respectively. No patient had a history of drug allergy. In the childhood AD group, 15.35% had a personal history of atopy, 36.44% had a family history of atopy, and 7.36% had both a personal and family history of atopy. A history of drug allergy was reported in 3.16% of children. In the infantile AD group, 79% had facial involvement, 42% had flexors affected, and 5.70% had both flexors and extensors affected. The types of eczema seen were acute in 52.72%, subacute in 23.35%, chronic in 23.35%, and follicular in 0.46%. In the childhood AD group, 74.50% had facial involvement, 35.53% had flexural involvement, 56.32% had extensor involvement, and 8.24% had both flexors and extensors involved. Acute eczema was seen in 28.79%, subacute in 23.38%, chronic in 47.40%, and follicular in 0.43% of the children.
SummaryBackground Vitiligo is an acquired disorder of pigmentation caused by loss of epidermal melanocytes. Autologous noncultured epidermal cell suspension (NCES) and autologous noncultured extracted hair follicle outer root sheath cell suspension (NCORSHFS) are important surgical modalities for the treatment of stable vitiligo. Objectives To compare NCES and NCORSHFS for producing repigmentation in stable vitiligo. Methods We randomized 30 patients with 47 stable vitiligo lesions into two groups. Patients in group 1 were treated with NCES, and those in group 2 with NCORSHFS. They were evaluated 16 weeks postsurgery for the extent of repigmentation, colour match, change in Dermatology Life Quality Index (DLQI) score and patient satisfaction. Results The extent of repigmentation was excellent (90-100% repigmentation) in 83% of lesions in the NCES group and 65% of lesions in the NCORSHFS group (P = 0Á154). Repigmentation ! 75% (good repigmentation) was observed in 92% of lesions in the NCES group and 78% of lesions in the NCORSHFS group (P = 0Á425). There was a significant improvement in DLQI score in both the groups, but the mean decrease among groups did not differ significantly (P = 0Á244). However, patients in the NCES group were significantly more satisfied than the patients in the NCORSHFS group. No significant difference was seen in colour match and pattern of repigmentation. Adverse effects were minimal. Conclusions Both NCES and NCORSHFS are safe and effective techniques with comparable efficacy. To the best of our knowledge, this is the first study directly comparing two different cellular techniques.
Background Vitiligo is an acquired depigmentation disorder of great cosmetic importance, affecting 1% of the general population. Photochemotherapy is the most commonly used treatment modality in extensive vitiligo, but is associated with many short-and 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.
NB-UVB performed better in comparison to TMP PUVA in terms of mean total repigmentation when traditionally considered therapy-resistant sites were excluded.
Childhood vitiligo is a common disorder of pigmentation in India. 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 vitiligo. Twenty-five children with vitiligo were treated with topical 0.03% tacrolimus ointment applied twice daily for 12 weeks. Response was noted as marked to complete (> 75% repigmentation), moderate (50-75% repigmentation) and mild (< 50% 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 mean 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 marked to complete in 11 (57.9%), moderate in five (26.3%) and mild in three (15.7%) children. Side effects were minimal, such as the pruritus and burning noted in only three patients. Topical tacrolimus is an effective and well-tolerated treatment modality in Asian children with vitiligo.
Background Although many treatment modalities have been tried for the treatment of vitiligo, none is uniformly effective. Psoralen phototherapy (psoralen ultraviolet A (PUVA)) is established as efficacious treatment for vitiligo. Recently, narrow-band UVB (NBUVB) has been reported to be an effective and safe therapeutic option in patients with vitiligo. Objective To compare the efficacy of PUVA and NBUVB in the treatment of vitiligo. Design and setting Retrospective analysis of 69 patients with vitiligo who were treated either with PUVA or NBUVB at the pigmentary clinic of the Dermatology Department of the Postgraduate Institute of Medical Education and Research, Chandigarh, India. Outcome measures The following variables were compared between the two groups of patients: repigmentation status, number of treatments for marked to complete repigmentation in existing lesions, appearance of new lesions or increase in size of existing lesions, adverse effect of therapy, stability of repigmentation and colour match. Results In PUVA-treated group, 9 patients showed marked to complete repigmentation (23.6%) and 14 patients showed moderate improvement (36.8%), whereas in NBUVB-treated group, 13 patients showed marked to complete repigmentation (41.9%) and 10 patients showed moderate improvement (32.2%). A statistically significantly better stability and colour match of repigmentation with surrounding skin was seen in NBUVB-treated patients. Conclusion We showed that NBUVB is more effective than PUVA and repigmentation induced with NBUVB is statistically significantly more stable.
