Effect of Narrow- band UVB on serum and tissue vitamin D level in vitiligo

AbstractBackgroundImmunologic background of vitiligo, role of vitamin D on its pathogenesis, role of NB-UVB on its treatment and its stimulatory effect NB-UVB on VDR expression are challenging area of research. The current study will focus on evaluating the effect of NB-UVB on serum and tissue level of vitamin D in vitiligo patients and correlating it with the degree of improvement.Aim of the studyThe aim of the present study is to evaluate and compare the serum and tissue vitamin D level in vitiligo patients before and after NB- UVB therapy and correlate them together and with the degree of improvement.Patients and methodsA case-control study included 16 vitiligo patients and 16 age and sex matched healthy controls. All patients will be examined by one dermatologist (demonstrating the extent of depigmentation according to rule of nines), and photographs will be taken before and after phototherapy to be evaluated by two different dermatologists to document the extent of repigmentation. Estimation of serum level of vitamin D by ELISAResultsFive of the 15 patients achieved more than 55% repigmentation; the mean duration of disease was 13 months. The remaining 10 patients had 30% - 40% repigmentation.
