Serum 25-hydroxyvitamin D status in chinese children with vitiligo: a case-control study

Background. Vitamin D can play a vital role in autoimmune diseases. Epidemiologic evidence demonstrates vitamin D deficiency excited in adult patients with vitiligo. Objectives. To investigate 25-hydroxyvitamin D (25(OH)D) levels in children with vitiligo and explore possible relevant factors. Methods. A total of 114 patients and 100 controls were included in our case-control study. We analyzed the required data collected by the questionnaire and examination to reveal the correlation with 25(OH)D levels. Results. The mean serum 25(OH)D levels in patients and controls were 43.62 ± 19.23 and 67.87 ± 19.45 nmol/L, respectively. The rate of deficient in patients and controls are 14.9% and 2%, respectively. There was significant difference between the 2 groups. Significant differences also existed on different ages comparing serum vitamin D levels of patients with controls ( P < .001). Age was an independent factor affecting 25(OH)D level ( P = .032). Two (1.8%) and 4 (3.5%) of children with vitiligo have comorbid autoimmune diseases and family history, respectively. There was no correlation between sex, duration of disease, type of vitiligo, skin lesion location, stage, family history, and comorbid autoimmune diseases with 25(OH)D levels. Conclusion. Serum vitamin D level was associated with onset vitiligo children. More sunshine and vitamin D fortified foods are necessary among children with age. The rates of children vitiligo with family history has decreased in China.
