Diagnostic and therapeutic implications of vitamin D deficiency in patients with warts: A case-controlled study.

BACKGROUND

Cutaneous warts are frequent conditions that possess much challenge to treat.

OBJECTIVE

To verify the potential role of vitamin D in the pathogenesis of viral warts by measuring the serum levels of vitamin D in patients diagnosed with viral warts compared to healthy controls and to verify whether oral vitamin D supplementation of those vitamin D-deficient patients would result in wart clearance.

METHODS

To evaluate the serum vitamin D levels, the study recruited 80 subjects, including 40 patients diagnosed with viral warts and 40 age- and sex-matched healthy controls. All patients were subjected to detailed history taking and examination to detect duration and type of warts. Serum vitamin D levels were measured using ELISA.

RESULTS

Thirty-five percent of patients had sufficient vitamin D levels (54-90 nmol/L), and 40% of patients had insufficient levels (50-80 nmol/L), while 25% of them had deficient levels (<50 nmol/L). In healthy group, 30% had sufficient levels, and 45% had insufficient levels, while 25% had deficient levels. There was an insignificantly lower serum level of vitamin D as well as an insignificantly deficient vitamin D status among patients compared to healthy controls.

CONCLUSION

Vitamin D serum levels appear to be lower among viral wart patients, and oral supplementation studies need to be more intensely investigated before elucidating its role; if any, in wart clearance.
