Paraoxonase 1 (PON1) 55 polymorphism, lipid profiles and psoriasis

Abstract

The PON1 55 M allele is a risk factor for psoriasis. Carriers of this allele have high levels of MDA, APOB and LP(a), a high APOB/APOA1 ratio and low ARE activity. These results indicate that oxidative stress, impairment of the antioxidant system and abnormal lipid metabolism may play a role in the pathogenesis and progression of psoriasis and its related complications. These data suggest that patients with psoriasis are more susceptible to vascular diseases.
