ABSTRACT
OBJECTIVE:
This study was designed to determine the serum lipid profile and the activity of paraoxonase (PON1, the lipophilic antioxidant component of high-density lipoprotein [HDL]-cholesterol) in acute pancreatitis.METHODS:
Acute pancreatitis was induced by injection of ethyl alcohol into the common biliary duct. Oxidative stress marker (malonyldialdehyde), lipid profile, and PON1 activity were determined in the serum.RESULTS:
In the acute pancreatitis group, whereas the mean levels of total cholesterol, low-density lipoproteins, and malonyldialdehyde were significantly higher (P < 0.001 for each), HDL level and PON1 activity were found to be significantly lower (P < 0.001 for each).CONCLUSIONS:
Our results suggest that an abnormal lipid profile and decreased PON1 activity may have a role in the pathogenesis of acute pancreatitis in which HDL-associated antioxidant defense is impaired.
