Changes in IL-17 serum levels after 3 months supplementation with vitamin D. A significant increase in serum IL-17 was detected at 3 month in the low dose vitamin D group (p = 0.037). Serum IL-17 response to high dose vitamin D was heterogeneous. 3 patients in each dosage group had IL-17 levels below the detection threshold of the ELISA kit at both time points (not shown in the figure).
