Background: Morphea and linear scleroderma are characterized by erythe
ma, induration, telangiectasia, and dyspigmentation, There is no unive
rsally effective treatment. Oral calcitriol has been beneficial in the
treatment of localized and extensive morphea/scleroderma, but the use
of topical calcipotriene has not been reported. Objective: The purpos
e of this study was to evaluate the efficacy and safety of topical cal
cipotriene 0.005% ointment in the treatment of localized scleroderma.
Methods: In a 3-month open-label study, 12 patients aged 12 to 38 year
s with biopsy-documented active morphea or linear scleroderma applied
calcipotriene ointment under occlusion twice daily to plaques for 3 mo
nths. The condition of each patient had previously failed to respond t
o potent topical corticosteroids and, for some patients, systemic medi
cations. Efficacy was assessed at baseline, 1 month, and 3 months. Lev
els of serum ionized calcium, intact parathyroid hormone, and 1,25-dih
ydroxyvitamin D and of random urinary calcium excretion were measured.
Results: During the 3-month trial, the condition of all 12 patients s
howed statistically significant improvement in all studied features. N
o adverse effects were reported or detected through laboratory monitor
ing of mineral metabolism. Conclusion: Topical calcipotriene 0.005% oi
ntment may be an effective treatment for localized scleroderma, but do
uble-blind placebo controlled studies are needed for confirmation.
