Bath psoralen–UVA photochemotherapy for localized scleroderma: experience from a single institute

SUMMARY

Background
Localized scleroderma (LS) comprises a spectrum of sclerotic autoimmune diseases primarily affecting the dermis. Various treatment modalities have been recommended for the management of LS, but only a few studies exist regarding the efficacy of bath PUVA photochemotherapy in the treatment of LS.

Objectives
To evaluate the efficacy of bath PUVA photochemotherapy in the management of LS in a retrospective study.

Methods
Twenty-eight patients (23 women and five men) with a diagnosis of LS, confirmed by histology, were included in the study. Patients were treated with a thrice-weekly regimen of bath immersion in 0.2 mg/1 water solution of 8-methoxypsoralen, followed by irradiation with UVA.

Results
Eleven patients (39%) showed complete remission (complete softening of the sclerotic plaques with or without postinflammatory hyper- or hypopigmentation) after a mean of 71 treatments (range 33–170) and a mean cumulative dose of 115 J/cm2 (range 11–232). Partial softening and regression of the sclerotic plaques was observed in 14 patients (50%). Three patients (10.7%) showed no effect, and in none of the patients was worsening noted
during treatment.
