Topical photochemotherapy for alopecia areata - 12/10/17
Résumé |
Twenty-two patients with alopecia areata were treated with a combination of topical 0.1% 8-methoxypsoralen and UVA (PUVA). Eight of the twenty-two patients (36.3%) responded with excellent regrowth (terminal hair in at least 75% of the treated scalp), and two patients (9.1%) showed good regrowth (terminal hair in 50% to 75% of the treated scalp). The mean total UVA exposure and the mean total number of treatments for the entire treatment course for these responders was 171.7 joules/cm2 and 47.4 treatments, respectively. Eight of the nine responders available for follow-up experienced some degree of relapse when PUVA treatments were tapered or during a follow-up period (mean, 8.3 months) after treatment was discontinued. Despite the failure of topical PUVA to change the long-term course of alopecia, the combination of PUVA with other therapeutic modalities may result in the prolongation of the beneficial effect in selected patients. The mechanism of action of PUVA in alopecia areata might involve an immunomodulatory effect.
