Background: Hyperhomocysteinemia and vitamin D deficiency maybe involved in the pathogenesis of vitiligo. This study comparedthe serum levels of vitamin D, homocysteine, vitamin B12, andfolic acid between vitiligo-affected children and healthy children.Methods: Using a case-control design, 30 children with vitiligoand 30 age and sex-matched healthy children were enrolledfrom April 2018 to August 2020. Serum levels of vitamin D,homocysteine, vitamin B12, and folic acid were analyzed in bothgroups during the same season of the year. Additionally, theassociation between serum levels of these factors with demographicand clinical features of the children (collected by interview andphysical examination) was evaluated. Data were analyzed usingthe independent T-test, Fisher’s exact test, and chi-squared test.Results: The vitiligo group had significantly lower vitamin Dand folic acid serum levels compared with the control group[95% CI -19.87 to -2.96 and -4.15 to -4.18, respectively]. Amongpatients, the vitamin D level was negatively correlated with age(r = -0.459, P = 0.011) and disease duration (r = -0.373, P = 0.042).Moreover, there was a significant association between vitiligoactivity and serum homocysteine levels (P = 0.027).Conclusion: Routine measurement of vitamin D and folic acidserum levels might be suggested, especially in children withlong-standing disease. Monitoring the homocysteine level maybe beneficial, particularly in children with progressive vitiligo.

Background: Basal cell carcinoma (BCC) is the most common form of malignancy in white populations. It has been hypothesized that dietary factors may play a role in BCC development. In this study, serum levels of folic acid and vitamin B12 were evaluated in patients with BCC to investigate the potential role of these vitamins in BCC development.Methods: Forty-five BCC patients and 45 age- and sex-matched healthy controls were enrolled in the study. Patients with a history of radiotherapy in the affected area were excluded. All participants completed a questionnaire including demographic characteristics, and blood samples were taken to evaluate serum levels of folic acid and vitamin B12.Results: There were no significant differences in serum levels of vitamin B12 and folic acid between healthy controls and BCC patients. Serum levels of vitamin B12 were significantly higher in female patients than male patients.Conclusion: It seems that BCC is not related to serum levels of vitamin B12 and folic acid; however, this issue should be studied with larger sample sizes.

Background and Aim: Vitiligo is a hypopigmentation disorder of the skin that is associated with depression and an impaired quality of life. There has been conflicting reports on the association between the disease and the serum levels of homocysteine, vitamin B12, and folic acid.In this study,serum levels of homocysteine, vitamin B12, and folic acid were evaluated in patients with vitiligo.Methods: Thirty patients with vitiligo and 30 age- and sex-matched healthy controls were recruited. Venous blood samples wereobtained from the study subjects and the levels of homocysteine, vitamin B12, and folic acid were measured. Data were analyzedusing non-parametric statistical tests.Results: No significant differences were found in the levels of serum homocysteine, vitamin B12, and folic acid between vitiligo patients and healthy controls. Moreover, there were no associations between these factors and age, body weight, gender,as well as the extent, duration, and type of vitiligo.Conclusion: It seems that vitiligo is not related to serum levels of homocysteine, vitamin B12, and folic acid.
