The efficacy of vitamin D3 supplementation in increasing 25-hydroxyvitamin D levels in childhood vitiligo patients receiving 308-nm-excimer light phototherapy

Abstract

Vitamin D deficiency is a condition often found in various autoimmune diseases, including vitiligo. There were clinical improvements in autoimmune patients who had been given oral vitamin D supplementation, as well as vitiligo patients. This study aimed to analyze the comparison effect of a combination therapy of 308-nmexcimer light phototherapy and vitamin D3 supplementation toward 308-nm-excimer light phototherapy alone to increase of serum 25-(OH)D levels in childhood vitiligo patients. Subjects consisted of 16 childhood vitiligo patients that divided into two groups; group I was given a combination of 308-nm-excimer light phototherapy and 5000 IU of vitamin D3 supplement once daily, while group II was given monotherapy of excimer light. There were highly significant increase of 25-(OH)D serum in both groups which were 324.00±119.066% and 29.84±36.106%, respectively. The very significant result was seen in a comparison of average increased of serum 25-(OH)D levels between both groups. The study concluded that combination of 308-nm-excimer light phototherapy and vitamin D3 supplementation gave a better effect than phototherapy only to increase of serum 25- (OH)D levels in childhood vitiligo patients.
