Increased lipid peroxidation in the erythrocytes of kidney stone formers.
The level of lipid peroxidation was significantly increased in erythrocytes and erythrocyte membrane in patients with stone disease. Increased activities of catalase and acetylcholinesterase in the erythrocyte membrane were observed, while hemolysate displayed no significant change in superoxide dismutase activity. The amount of phospholipids in the RBC membrane of patients was significantly increased. Peroxidation was stimulated by oxalate in vitro and was further enhanced in the presence of ferrous ion. The changes in lipid peroxidation and antioxidant enzymes are suggestive of chemical alteration of the RBC membrane during urolithiasis.
