Assessment of serum vitamin D level in patients with cutaneous warts: a case-control study

Background: The use of vitamin D and its analogues in the treatment of warts has been to be effective and painless without any considerable side effects, unlike some other routine safe and effective therapeutic modalities such as cryotherapy that in some cases is really difficult to perform due to related pain, especially in the children. Owing to a probable relationship between the deficiency of serum vitamin D and warts, this research aimed to find the association between level of serum vitamin D and warts. Methods: This case-control study was conducted on 56 subjects in Rasoul Akram Hospital, Tehran, Iran, for 18 months. The subjects were randomly divided into case and control groups, including 28 age and sex-matched subjects in each of them. The required data were extracted through a questionnaire. Finally, the data were analyzed in the SPSS software V.22 using tests such as Mann-Whitney and Pearson correlation. Results: In this study, 56 people were examined, and 28 subjects were included in both case and control groups. The mean serum level of vitamin D in both case and control groups was 23.564and 31.593, respectively. The association between serum levels of vitamin D in the group with and without wart was not significant in both men and female groups. Serum vitamin D levels were compared in two groups of under 18 years old and between 18 and 50 years old, which were not statistically significant. Conclusion: According to our results, there is no significant relationship between serum vitamin D levels and existence of warts. This relationship is not statistically significant at the level of age and sex variables, and there is no difference in age and gender between the case and control groups.
