PUVA treatment of vitiligo: a retrospective study of Turkish patients

Psoralen plus ultraviolet A (PUVA) is considered to be the treatment of choice for subtotal vitiligo; however, it is time consuming and carries certain health risks for both patients and physicians. This study attempts to evaluate the efficacy of the treatment in Turkish vitiligo patients.

We have performed a retrospective study of 33 patients with vitiligo who received systemic PUVA therapy during the period 1985 to 1997, and have evaluated their response to treatment.

Overall, 28 patients (84%) showed some improvement; 12 patients experienced a repigmentation of 51-75% and six patients achieved greater than 75% repigmentation. Face and trunk lesions showed better repigmentation than other areas, whereas hands, feet, perioral, and periorbital areas were generally refractory to treatment. The age of the patient, age at onset of the disease, sex, disease duration, and degree of depigmentation prior to initiation of therapy had no influence on PUVA-induced repigmentation.

The distribution of vitiliginous skin must be taken into consideration before the initiation of PUVA therapy, as the response to treatment varies greatly with different body sites; hands, feet, perioral, and periorbital regions are particularly treatment resistant.
