Vitiligo is a non-communicable skin disease, with an average prevalence at 0.4-2.1% of the total population that dips and spikes outside this range in some ethnic subgroups. Its ethiopathogenesis is complex and involves the interplay of multiple factors. Aberrations of melanocytes are responsible for vitiligo onset. Immune system mistakenly identifies these melanocytes as intruders and actively seeks to destroy them.
Nearly half of vitiligo cases have a childhood onset. Three visually different forms are diagnosed, based on the distribution of lesions – non-segmental, segmental and mixed vitiligo, – although difference between the first two is often elusive. They have different treatment approaches, with different therapeutics, timelines and outcome expectations.
Four age psychological categories are often used during a pediatric vitiligo patient evaluation: (a) 0-3 years, (b) 4-8 years, (c) 9-12 years, and (d) 13+ years of age, differentiated by ability to participate in therapy, self-image development and susceptibility to bullying.
Management of pediatric vitiligo should take into account several factors, including location, extension, activity, psychological impact, – in the context of the child’s age, and possible associations with autoimmune diseases among close relatives. The treatment protocol needs to be tailored to individual health condition, in order to avoid negative effects on the overall growth and psychological development of the child.
An early intervention, typically within first 2-3 months of the lesion development, provides better outcomes. The first line of treatment typically includes topical corticosteroids and calcineurin inhibitors of different potency. The second line includes a cautious introduction of UVB phototherapy, based on age and disease severity, in combination with topical treatments. Microsurgery is not recommended in pediatric age. Treatment duration in pediatric age commonly ranges from 3 to 8 months, with nearly 80% success rate. Strict compliance to the protocol greatly improves the outcomes. Screening for co-morbidities – e.g. celiac disease or thyroid disease – may be required to rule out the underlying or borderline conditions.
A life-long supporting skincare is necessary to achieve acceptable and continuous cosmetic results, and to reduce chance for symptomatic recurrence rate after a successful treatment.
