Abstract
Objective: To investigate the difference of serum vitamin B12 levels between patients with non-segmental vitiligo compared with healthy people, and the relationships of serum vitamin B12 levels with clinical characteristics of these patients. Subject and method: A comparative cross-sectional descriptive study on patients with non-segmental vitiligo and healthy people at Ho Chi Minh city Hospital of Dermatology and Venereology. Diagnosis was based on clinical and Wood's lamp examination. Quantitative assay of serum vitamin B12 levels were measured by two-step immunoassay using chemiluminescent microparticle technology. Result: 46 patients with non-segmental vitiligo and 44 healthy people were included. The serum vitamin B12 concentration in the group of patients with non-segmental vitiligo was significantly lower than that of the control group ([553.15 (382.2-783.6) pg/mL vs. 612.55 (525-792.3) pg/mL, p<0.05]). The progressive vitiligo group had statistically significant lower serum levels of vitamin B12 than the control group [441.60 (290.50-620.00) and 612.55 (525.00-792.30) pg/mL, p<0.05], this was not observed in the stable group compared with the control group (p>0.05) and between the progressive and stable group (p>0.05). Conclusion: Serum levels of vitamin B12 in the group of patients with non-segmental vitiligo were significantly lower than that in the healthy group. There was the reduction in serum vitamin B12 levels in the group of patients with progressive non-segmental vitiligo compared with the control group. There was no decrease in serum vitamin B12 levels in the stable group compared with the control group as well as between the progressive and stable group.
