Following the treatment, there was a significant increase in the levels of 25(OH)D3 and a significant decrease in the levels of PTH among patients with vitiligo. The serum concentrations of PTH and 25(OH)D3 were inversely correlated. Of the 16 patients with vitiligo, 14 achieved a repigmentation level ranging from 25% to 75%. Here, PTH is linked to vitiligo.
