title: Combination of PUVAsol and topical calcipotriol in vitiligo.
abstract: BACKGROUND
  A large variety of therapeutic agents are being tried for the treatment of vitiligo, but psoralens continue to be mainstay of treatment although they are not uniformly effective. Recent advances in pathophysiology have established a perturbed calcium homeostasis in affected skin, and melanocytes were shown to express vitamin D3 receptors.
  
  
  OBJECTIVE
  The purpose of present study was to determine the efficacy of the combination of PUVAsol with topical calcipotriol in the treatment of vitiligo.
  
  
  METHODS
  Nineteen patients with essentially bilateral symmetrical lesions were enrolled in a randomized, double-blind, right/left comparative study of 18 months duration. An oral dose of 0.6 mg/kg 8-methoxypsoralen was given 2 h before exposure to sunlight thrice weekly to all patients. The patients were advised to apply calcipotriol (50 microgram/g) on one side of the body and placebo ointment over the lesions on the other side twice daily.
  
  
  RESULTS
  At the end of 6 months, 12 patients (70%) showed marked to complete improvement on calcipotriol-treated sides as compared to 6 patients (35%) showing similar improvement on placebo-treated sides (p <0.05). At the end of treatment, 13 patients (76%) showed marked improvement in calcipotriol-treated lesions whereas 9 patients (53%) showed moderate to marked improvement in placebo-treated lesions. The repigmentation of hands and feet was much better with the combination of PUVAsol and calcipotriol.
  
  
  CONCLUSIONS
  The combination of PUVA and calcipotriol is highly effective and works faster and may be used for shortening the therapy with PUVA in the treatment of vitiligo.
