摘要
Serum paraoxonase (PON1) and antibodies to oxidized-LDL (anti ox-LDL) were measured in chronic renal failure subjects on renal replacement therapy such as hemodialysis (HD) peritoneal dialysis (PD) and transplantation (Txp). Paraoxonase activity was significantly lower in HD and PD group (P<0.001) than in control subjects. In transplant patients, paraoxonase activity was not significantly different from that of controls. Antibodies to ox-LDL was significantly higher in HD, PD and Transplant patients (P<0.0001) compared to control subjects. High titers of antibodies were observed in the HD group compared to the PD and Transplant subjects. A decrease in paraoxonase activity and high titers of Antibodies to ox-LDL in the dialysis group suggest a decreased cardio protective effect of HDL and enhanced risk of premature cardiovascular complications. Whereas in case of transplant subjects, there seems to be restoration of PON1 activity, but elevated levels of anti-oxLDL could still be a potential atherogenic factor. Hence, we propose that estimation of these two parameters can be used as a useful index to measure the cardiac risk in the above patient category.
