The Glutathione S-Transferase Activities in the Evaluation Acute Viral Hepatitis B and Chronic Alcoholic Liver Disease | Chapter 04 | New Insights into Disease and Pathogen Research Vol. 3
Glutathione S-Transferase is an
important hepatic detoxifying enzyme. Half-life of GST alpha in plasma is about
1 hr; its concentration follows the changes in the hepatocellular damage more
rapidly than aspartate amino transferase (AST) or alanine amino transferase
(ALT).
Aim and Objectives: To validate
chronic alcoholic liver disease and acute viral hepatitis B could produce any
significant changes in serum glutathione S-transferase activities.
Materials and Methods: A total of
120 samples were used in the present research. 20 hepatitis B patient 40
chronic alcoholic hepatitis patients and 60 age and sex matched control
subjects. Serum GST activity and standard LFT (Liver Function Test) parameters
done.
Results: GST activity showed a
significantly increase (p value< 0.001) in chronic alcoholic liver disease
patients (22.293±4.159 IU/L vs 20.127±4.789 IU/L) and in acute viral hepatitis
(23.685±6.751 IU/L vs 20.127±4.789 IU/L). In multiple logistic regression
analysis when GST measurement was added to a LFT, the diagnostic significance
increased from R2=0.792 to 0.884 in acute viral hepatitis B and from R2= 0.843
to 0.849 in chronic alcoholic cirrhosis. Standard LFT parameters are
significantly different in both groups. Area under ROC (Receiver Operative
Characteristic Curve) is 0.952 for model having albumin+ ALT which is increased
to 0.992 after addition of GST in previous model in acute viral Hepatitis B.
While in alcoholic Hepatitis Area under ROC is 0.966 for model having albumin+
ALT which is increased to 0.974 after addition of GST in previous model.
Conclusion: GST activity may provide
additional LFT measurement to the current battery of tests to differentiate
acute hepatitis B and alcoholic liver disease from normal population and may
improve the evaluation of Hepatitis B virus and alcoholic cirrhosis when added
to routine LFT parameters.
