IL17A and psoriasis: Most patients with moderate-to-severe psoriasis (PASI > 10) and CVD had IL-17A levels below 2.3 (9 vs. 1 patient), whilst patients with moderate-to-severe psoriasis but no CVD had IL-17A levels above 2.3 (10 vs. 3 patients), and an IL-17A level below 2.3 was associated with increased incidence of CVD (odds ratio 24.46, p = 0.0028, 95% confidence interval 2.1–1425.1).
