To Study the Activity of Paraoxonase-1 and High Density Lipoprotein-Cholesterol in Alcoholic Liver Cirrhosis
Journal Title: Journal of Krishna Institute of Medical Sciences University - Year 2017, Vol 6, Issue 1
Abstract
Background: Alcoholic liver cirrhosis is the most common complication of ethanol abuse. Alcoholic fatty liver progresses to alcoholic hepatitis, cirrhosis and liver failure. Lipoproteins are synthesized by the liver and secreted into the circulation. Alcoholic liver cirrhosis causes alteration in lipoprotein metabolism producing liver steatosis and necrosis. Paraoxonase-1 (PON-1) is an enzyme synthesized in liver and has an esterase activity towards lipid peroxides and circulates in plasma bound to High-Density Lipoproteins-cholesterol (HDL-c). Aim and Objectives: To determine the activity of PON-1 and levels of HDL-c in alcoholic liver disease and to correlate PON-1 activity with HDL-c. Materials and Methods: A Cross sectional study done in Department of Biochemistry and Department of Medicine, Belagavi Institute of Medical Sciences, Belagavi, Karnataka, India, from 1st December 2014 to 31st January 2016 Study included 50 males (age range 25-55 years) with alcoholic liver cirrhosis and 50 healthy male participants (age range 25-55 years). PON-1 activity was estimated using spectrophotometric method by the hydrolysis of phenylacetate. HDL-c level was measured by cholesterol oxidase-peroxidase method. Results: The serum PON-1 activity and levels of HDL-c in patients with alcoholic liver cirrhosis were significantly reduced (p<0.001) compared with controls. Conclusion: A significant decrease in PON-1 and HDL-c in alcoholic liver cirrhosis may contribute to the risk of atherosclerosis in alcoholic liver cirrhosis patients.
