[Repigmentation treatment of vitiligo with L-phenylalanine and UVA irradiation]

20 patients suffering from vitiligo (17 with generalized, 3 with localized type) were treated with L-phenylalanine and UV-A irradiation (PAUVA). The dose of L-phenylalanine was 50 mg/kg per os. In 85% of the patients, this therapy resulted in a follicular and partially confluent repigmentation, which did not exceed 50% of the vitiliginous area.
