Abstract

Abstract:

Background : Vitiligo is a common pigmentary  disorder with great cosmetic and psychological morbidities . Although many  treatment modalities have been tried for the treatment of vitiligo , none is uniformly effective. PUVA (Psoralen Ultra Violet A) is established as efficacious treatment for vitiligo. Recently, narrow band UVB(NBUVB) has been reported to be an effective and safe therapeutic  option in patients with vitiligo. In this study, patients with vitiligo  divided into two groups that   were treated either with UVB or PUVA therapy modalities and the efficacy ,the time required for repigmentation, stability of repigmentation and adverse effects were compered in two groups.

Methods: A clinical trial has been performed on 60 patients with vitiligo referred to BOUALI hospital  and MEHREGAN laser center in 1392 and  treated with UVB and PUVA therapy methods.

In first group that were  treated with PUVA (30 patients), oral   tablets containing 8-methoxypsoralen at a dose of 25 mg/ m2 were taken 3 hours  before  phototherapy and PUVA therapy was started at a dose of 0.5 J/cm2 twice a week. The phototherapy dose was increased by 20%  in each visit  if tolerated.

In second group( 30 patients) , UVB therapy was administered twice a week  with 311-313 nm wavelength and a dose of 0.1 J/cm2 and we increased the dose 20% in each visit if tolerated .phototherapy sessions in both groups were  15. In patients treated with PUVA , 40% were male (12 patients) and 60% were female(18 patients).In UVB group 43.3% were male (13 patients) and 56.7% were female(17 patients).The mean age in PUVA- treated group is 34 years and in UVB- treated group is 32.1 years. There was no statistically significant difference on comparing mean age in both groups.(p=0.13). Type of vitiligo in patients treated with PUVA was 56.7% generalized, 30% segmental and 13.3 % focal ,and in patients treated with UVB was 56.7 % generalized,33.3% segmental and 10% focal.
