BACKGROUND: Recent advances in the pathophysiology of vitiligo have demonstrated defective calcium homeostasis in depigmented skin. 1,25-Dihydroxyvitamin D3 may be involved in the regulation of melanin synthesis, and receptors for 1,25-dihydroxyvitamin D3 have been demonstrated on melanocytes.
OBJECTIVES: We conducted an open study to determine the efficacy and tolerability of calcipotriol cream as monotherapy and in conjunction with psoralen plus ultraviolet A (PUVA) in the treatment of vitiligo.
METHODS: Twenty-six patients with vitiligo affecting 5-40% of their skin were recruited. Twenty-two were treated with twice-daily topical calcipotriol monotherapy (50 microg g(-1)) and four were placed on combination treatment with twice-daily topical calcipotriol 50 microg g(-1) in conjunction with topical or oral 8-methoxypsoralen PUVA three times weekly.
RESULTS: Treatment was well tolerated at all sites and no adverse effects were reported. After a therapy time of 3-9 months (mean 6 months), 77% (17 of 22) of those treated with monotherapy showed 30-100% improvement, and three of the four patients on combination treatment showed good response.
CONCLUSIONS: Topical calcipotriol appears to be an effective and well-tolerated treatment for vitiligo and can be safely used in conjunction with PUVA, but controlled studies are necessary to exclude the possibility of spontaneous repigmentation.
