CAT and psoriasis: A study by Nemati et al. [44] conducted in a group of 100 psoriasis patients revealed that elevated lipid and lipoprotein levels (particularly TC, LDL, Lp(a), and ApoB) as well as reduced levels of antioxidants (SOD, CAT, PON1) may cause accumulation of ox-LDL and ROS in psoriasis patients, which in turn may play an important role in the context of immunological inflammatory states causing skin cell damage or arterial atherosclerosis in psoriasis patients.
