Background The epidermal accumulation of hydrogen peroxide (H2O2) has been documented in vitiligo. Aim To assess the effect on disease cessation and repigmentation of the reduction/removal of H2O2 using low-dose, narrow-band, ultraviolet-B (UV-B)-activated pseudocatalase PC-KUS in 71 children with vitiligo. Methods This uncontrolled and retrospective study included 45 girls and 26 boys (mean age, 10.3 years) who applied topical PC-KUS twice daily to the entire body surface without narrow-band UV-B dose increments. The affected body areas were documented by special photography at the first visit and after 8,12 months. The response was evaluated by two independent physicians as > 75% vs. < 75% total repigmentation of the face/neck, trunk, extremities, and hands/feet. Generalized (n = 61) and segmental (n = 10) vitiligo were evaluated as different entities. The effect of total-body, low-dose, narrow-band UV-B (0.15 mJ/cm2) monotherapy once daily without any increments and without application of PC-KUS was tested over 6 months in 10 children with vitiligo vulgaris (mean age, 8.4 years). Results One hundred per cent cessation was observed in 70 of the 71 children. More than 75% repigmentation was achieved in 66 of 71 patients on the face/neck, 48 of 61 on the trunk, and 40 of 55 on the extremities; however, repigmentation on the hands/feet was disappointing (five of 53). The response was independent of skin color, age of onset, duration of disease, other demographic features, and previous treatments. The follow-up after narrow-band UV-B monotherapy showed no significant repigmentation in all areas. Seven of 10 patients showed progression of their vitiligo. Conclusion A reduction in epidermal H2O2 using low-dose, narrow-band UV-B-activated pseudocatalase PC-KUS is an effective treatment for childhood vitiligo which can be safely performed at home.

Vitiligo Treatment in Childhood: A State of the Art Review

PEDIATRIC DERMATOLOGY, Issue 5 2010

Approximately half of the affected individuals develop the disease before adulthood. Etiologic hypotheses for vitiligo include biochemical, neural and autoimmune mechanisms. The most compelling of these suggests a combination of genetic and immunologic factors that result in an autoimmune melanocyte destruction. We reviewed studies carried out on various treatment modalities used in childhood vitiligo. Topical corticosteroids were found to have excellent repigmentation rates, whereas calcineurin inhibitors have comparable efficacy and a better safety profile compared with topical corticosteroids. These two groups of topical medications are good first-line treatment modalities for localized vitiligo. For the treatment of generalized vitiligo, phototherapy has excellent efficacy. Narrow-band ultraviolet B (UVB) has better overall repigmentation rates and safety profile than either topical or oral psoralens and ultraviolet A (PUVA). Other treatment modalities may be considered depending on a patient's specific condition, such as surgical options and depigmentation. With adequate sun protection, the option of no treatment with or without corrective camouflage, is an innocuous alternative to any of these treatment modalities. [source]

Impact of childhood vitiligo on adult life

BRITISH JOURNAL OF DERMATOLOGY, Issue 4 2008

Summary Background, The onset of vitiligo occurs before the age of 20 years in 50% of patients. Having a chronic disease in childhood can impede a child's health-related quality of life (HRQL). Objectives, Firstly, to compare the social and psychosexual development and current HRQL of young adult patients with childhood vitiligo with those of a group of healthy controls. Secondly, to compare these outcomes in patients reporting negative childhood experiences with those of patients not reporting negative childhood experiences. Methods, Eligible patients were mailed questionnaires on (i) sociodemographic and clinical characteristics, (ii) social and psychosexual development, (iii) generic and dermatology-specific HRQL, (iv) presence of negative childhood experiences related to vitiligo, (v) specification of these negative experiences and (vi) patients' recommendations for further care. Results, A total of 232 patients with vitiligo completed the questionnaires. Social and psychosexual development and generic HRQL in young adult patients with childhood vitiligo were not different from those of healthy controls. However, patients reporting negative childhood experiences reported significantly more problems in social development than those not reporting negative experiences. Furthermore, negative childhood experiences were significantly associated with more HRQL impairment in early adulthood. Conclusions, Reporting negative experiences from childhood vitiligo appears to be associated with HRQL impairment in young adults with vitiligo. [source]
