Atorvastatin in Active Vitiligo

Atorvastatin in Active Vitiligo: a Bicentric Prospective Randomized Trial

Condition:

Non segmental and active vitiligo of adulthood.

Main objective:

To evaluate the efficacy of a daily treatment with atorvastatin 80mg/d combined to UVB compared to UVB alone in active vitiligo after 6 months of treatment.

Methods:

Prospective interventional bicentric study with evaluation blinded to the treatment received.

Inclusion criteria:

Patients from 18 to 75 year-old with active non segmental vitiligo. Active is defined by the apparition or the modification of vitiligo lesions with the past 3 months and under Wood's lamp examination hypochromic borders and/or spotty depigmentation.

Interventions:

After central randomization

• Arm A : atorvastatin 40mg/d for 1 months then 80mg/d for 5 months combined with twice weekly narrowband UVB treatment for 6 months.
• Arm B: with twice weekly narrowband UVB treatment for 6 months.

Evaluation:

Main criteria: Decrease of VASI score expressed in percentage Secondary criteria: Decrease of VETF score expressed in percentage. Variation of PGA and DLQI scores. Clinical and biological tolerance. Variation of CXCL10 levels in the serum.

Length of the study:

Inclusion period: 12 months. Length of treatment: 6 months. Statistical analyses and drafting the article: 6 months. Total length: 24 months.

Inclusion Criteria:

• Active non-segmental vitiligo defined by

  • Non- segmental vitiligo with new patches or extension of old lesions during the last 3 months AND
