Background: Generalized vitiligo is characterized by autoimmunedestruction of melanocytes, which results in patches of thedepigmented skin and the overlying hair. Vitamin D is an essentialhormone synthesized in the skin and is responsible for skinpigmentation. Low vitamin D levels have been noted in patientswith a variety of autoimmune diseases. A recent study showedthat low vitamin D levels may be associated with vitiligo. Theaim of this study was to compare 25-hydroxyvitamin D (25[OH]D) levels in Iranian patients with vitiligo with normal controls.Method: In this case-control study, we studied 30 newly diagnosedpatients with vitiligo and 30 healthy controls through a casecontrol design. Two groups were matched for gender, age, andthe season in which the serum levels of 25-hydroxy vitamin Dwere measured. The serum levels were categorized as sufficient,insufficient and deficient.Result: The mean serum level of vitamin D was 10.24±1.27 ng/mL in patients compared to 18.31±7.39 ng/mL in the controlgroup. Male patients had lower levels of vitamin D compared tocontrols (7.25 ng/mL vs. 13.31ng/mL, P=0.03), while no significantdifference was observed between females and controls (14.12 ng/mL vs. 16.25 ng/mL, P=0.51).Conclusion: The present study demonstrated that there may be anassociation between low levels of Vitamin D3 and vitiligo in men.

Background: Different modalities have been tried in order totreat stable vitiligo. Culturing melanocytes is time consumingand expensive. Therefore, new methods using autologousmelanocytes are sought. We aimed to compare the mixed nonculturedautologous melanocytes of the outer root sheath andthe bulge area of hair follicle transplantation plus dermabrasionwith dermabrasion alone in stable generalized vitiligo patchesrepigmentation.Method: Eight patients with stable generalized vitiligo wererecruited. Two patches were selected and assigned to one of thestudy groups: one was treated with dermabrasion alone, andthe other was treated with dermabrasion and transplantation.Uncultured melanocytes were extracted from the patients’ hairfollicle outer root sheath and bulge. The patches were assessedmonthly for the next six months. The primary outcome was todetermine the percentage changes of the depigmented patchesfrom the baseline.Result: Although the repigmentation changes were statisticallysignificant in transplantation patches, there was only one patchwith good and another with fair pigmentation. Furthermore,seven patches without and one patch with poor pigmentationwere observed as control lesions. The transplanted patchesdemonstrated a significantly better repigmentation rate in contrastto their controls (p=0.03).Conclusion: Although this method is fast and economic, theclinical response was not satisfactory.
