Narrow-band LTVB treatment of vitiligo in Chinese

Narrow-band ultraviolet B (NBLTVB) phototherapy has recently been reported to be an effective and safe treatment modality for vitiligo. In the present report, we evaluated the efficacy and safety of NBLTVB therapy for vitiligo in Chinese patients. Seventy-two vitiligo patients treated from 2000 to 2003, were included retrospectively (male: female=33:39, mean age: 38.5). Among them, 61 were non-segmental type and 11 the segmental type. Treatments were given two to three times a week for a maximum period of one year with an initial dose of 0.2 J/cm(2) and a 0-20% increment each session (mean accumulation dose: 155.3 J/cm(2)). Computer image analysis by Supervise classification was used to estimate the area of vitiligo involvement before and after treatment. An excellent response (75-100% area of repigmentation) was obtained in 9 patients (12.5%) and a good response (50-75%) in 24 (33.3%), a moderate response (25-50%) in 20 (27.8%), and a poor response (0-25%) in 19 (26.4%). In summary, 45.8% of our patients had more than 50% repigmentation. Burns were a side effect in 5 patients (7%) and transient erythema with itching or xerosis was noted in 5 patients (7%). These results indicate that NBLTVB phototherapy is an effective and safe treatment choice for generalized vitiligo.
