Plasma lipid changes in psoriatic children.

Plasma lipid, lipoprotein and apoprotein concentrations were determined in psoriatic children and in healthy controls. The plasma total cholesterol (TC) was higher than in controls (p = 0.03). The higher cholesterol levels were explained by an almost significant increase in cholesterol associated with high-density lipoproteins and by the tendency towards higher values of cholesterol associated with low-density lipoproteins and very-low-density lipoproteins. No significant changes of plasma triglycerides were observed. Levels of apoproteins (apo) AI and apo B were not significantly different in psoriatic children; however, the levels of apo B were correlated differently with plasma TC in psoriatic children, and the ratio TC/apo B was significantly increased in patients with respect to the controls, suggesting some differences of plasma lipoprotein lipid/apoprotein relationship in psoriasis.
