Pre-treatment vitamin B12, folate, ferritin, and vitamin D serum levels in patients with warts: a retrospective study.

Aim: To compare the serum levels of 25-hydroxyvitamin D, ferritin, folate, vitamin B12, zinc, and thyroid stimulating hormone between patients with warts and healthy individuals.

Methods: This retrospective study enrolled 40 patients with warts and 40 healthy individuals treated at the Ufuk University Hospital, Ankara, between July and December 2017. Serum levels of 25-hydroxyvitamin D, ferritin, folate, vitamin B12, zinc, and thyroid stimulating hormone status were evaluated retrospectively.

Results: Participants with and without warts had similar mean serum 25-hydroxyvitamin D, ferritin, folate, zinc, and thyroid stimulating hormone levels. However, patients with warts had significantly lower mean serum vitamin B12 level (P=0.010). Patients with warts non-significantly more frequently had decreased serum levels of 25-hydroxyvitamin D, ferritin, and folate (P=0.330, P=0.200, P=0.070, respectively).

Conclusion: Patients with warts may require evaluation of serum levels of vitamin B12, folate, ferritin, and vitamin D.
