Background: Hepatistis C virus (HCV) affects approximately 170 million people, and it is the leading cause of the chronic liver disease. The destruction of liver cells is reflected by an increase of different enzyme activities in the serum. These enzymes include alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), which play a significant role in the metabolism of many biological substances and exist mainly in the liver. In this study we investigated the activity of alcohol dehydrogenase and its isoenzymes and the total activity of ALDH in the sera of patients with hepatitis C.
Methods: Serum samples were taken for routine biochemical investigations from 50 patients with hepatitis C and from 50 healthy subjects. The activity of class I and II ADH isoenzymes and ALDH activity were measured by spectrofluorometric methods. For the measurement of total ADH activity and activity of class III and IV isoenzymes, the photometric methods were used.
Results: The analysis of our results shows a statistically significant increase in the activity of ADH I and ADH II (2.5-fold and 2-fold, respectively). Activities of both classes of alcohol dehydrogenase isoenzymes have good correlation with alanine and aspartate aminotransferase. The observed increase in total alcohol dehydrogenase activity was not very high but confirmed the elevation of class I and II isoenzyme activity.
Conclusions: We can state that the activity of class I and II alcohol dehydrogenase isoenzymes in the sera of patients with hepatitis C is increased and it seems to be caused by the release of these isoenzymes from damaged liver cells.
