Anti-psoriatic therapy recovers high-density lipoprotein composition and function.

ABSTRACT: Psoriasis is a chronic inflammatory disorder associated with increased cardiovascular mortality. Psoriasis affects high-density lipoprotein (HDL) composition, generating dysfunctional HDL particles. However, data regarding the impact of anti-psoriatic therapy on HDL composition and function are not available. HDL was isolated from 15 psoriatic patients at baseline and after effective topical and/or systemic anti-psoriatic therapy and from 15 age- and sex-matched healthy controls. HDL from psoriatic patients showed a significantly impaired capability to mobilize cholesterol from macrophages (6.4 vs. 8.0% [(3)H]cholesterol efflux, P<0.001), low paraoxonase (217 vs. 350 μM(-1) minute(-1) mg(-1) protein, P=0.011) and increased Lp-PLA2 activities (19.9 vs. 12.1 nM(-1) minute(-1) mg(-1) protein,
