Abstract:
To evaluate the efficacy of different courses of Narrowband Ultraviolet B phototherapy ( NB-UVB) in the treatment of vitiligo .50 vitiligo patients who had finished 3 courses of phototherapy and met the inclusion criteria were included in our study .Each course contained at least 30 times of phototherapy , and between two courses , there was a rest of 3~6 months .The repigmentation of each vitiligo lesion after every course of phototherapy was recorded .To the same lesion , the efficacy difference between the first course and the second course was not statisti -cally significant.But the efficacy of the first course was better than the third course (P<0.05),while the efficacy of the second course was also better than the third course ( P<0.05 ) .There was no significant difference among the three courses concerning the average single irradiation dose .In conclusion , when using NB-UVB in treating vitili-go, the efficacy of first course was equivalent to the second course , but it reduced in the third course .Whenever a plateform stage occurs , a rest of more than 3 months is long enough for the vitiligo lesion to recover initial light sen-sitivity.
