Efficacy of treatment of vitiligo patients with the ultrasonic excimer laser
Results of treatment of 25 vitiligo patients with the ultrasonic laser with the wavelength of 308 nm were assessed. The median value of the number of procedures was 28 while the course irradiation dose was 11.7 J/cm2. Repigmentation of over 15% and more than 50% of affected areas was observed in 51 (72.9%) and 26 (37.1%) vitiligo foci, respectively The best results were registered in the affection foci located on the face and neck while foci located on the hands, thighs and feet turned out to be the least sensitive. A positive effect was observed statistically much more often in the group of patients receiving more than 20 procedures per course of treatment vs. the group receiving less than 20 procedures (P=0.003). In the course of two-year follow-up of seven patients after the end of treatment, exacerbation of the disease was observed in three patients (42.9%) while repigmentation in the foci taking place in the course of treatment preserved in all of the patients
