Early localized vitiligo, a medical emergency: Long-term follow-up study

In spite of multiple therapeutic regimens for vitiligo, disease relapse remains a challenge. Most guidelines consider systemic treatments only in rapidly progressive disease with wider surface areas. This delay in halting the immune attack, may give the chance for further disease progression as well as establishment of resident memory T-cell population predisposing to future relapses. To assess the ability of early systemic therapy of localized (<2% BSA), recent onset (<6 months) vitiligo to control disease activity and minimize the possibility of recurrence. Twenty-five patients with recent onset (<6 months), localized (<2% BSA) vitiligo were included. Patients received pulse dexamethasone therapy for 6 months plus topical treatments and NB-UVB sessions. Patients were followed monthly as regards percent of repigmentation and VIDA score. To detect recurrence, biannual assessment was done for 4 years. Eighty-four percent of patients had acrofacial lesions and 44% had facial lesions. Arrest of activity was achieved after 3.65 ± 2.19 months. Complete repigmentation was achieved in a mean duration of 6.88 ± 0.2 months. At the end of the 4-year follow up, recurrence occurred in 32% of patients. In spite of recurrence, localized disease (<2% BSA) was secured. A significantly higher incidence of recurrence was associated with cases with bilateral distribution of lesions. Early systemic immunomodulation for recent localized vitiligo is a successful approach to achieve early control of disease activity and minimize the incidence of recurrence. Such cases should not be overlooked but managed as early as possible; it is a race against time.
