Psoriasis vulgaris patients with atherosclerosis had higher levels of hs-CRP (median = 1.22; interquartile range—IQR = 0.34–12.11) and IL-17A (median = 1.30; IQR = 0.43–4.28), but a lower level of TNF-α (median = 0.54; IQR = 0.13–3.41) compared to those without atherosclerosis (p < 0.05). Here, TNF is linked to psoriasis vulgaris.
