Repigmentation in Vitiligo: PUVA vs. Narrowband UVB

This study clearly demonstrates that for vitiligo repigmentation, NB-UVB is safer and more effective than PUVA. Other randomized, controlled trials have shown at least some efficacy with targeted phototherapy, topical and systemic steroids, topical calcineurin inhibitors, and calcipotriene combined with PUVA. A number of reports show success with surgical repigmentation procedures, as well. Although we are making progress in treating this vexing disease (especially with calcineurin inhibitors and phototherapy), we still have a long way to go. At best, 75% of patients respond, and in most instances, this response is only partial. A breakthrough in the management of this disease would be greatly welcomed by both patients and doctors. An accompanying editorial provides a nice evidence-based review of existing therapies for vitiligo.

UVB311 Folic acid and Vitamin B12

Repigmentation was notable in lesions on the face, neck and throat, lower arm, chest, back and lower legs, whilst repigmentation on the hands, wrists, feet and ankles proved to be minimal. Maximum repigmentation rates did not differ significantly between the UVB group and the UVB+ group. Our study reconfirms that narrow band UVB phototherapy is an effective treatment for vitiligo and shows that co-treatment with vitamin B12 and folic acid does not improve the outcome of treatment of vitiligo with narrow band UVB phototherapy.
