AbstractBackground and objectives: The aim of the current study was to assess the use of determinations of total alcohol dehydrogenase and the activity of its isoenzymes as well as aldehyde dehydrogenase in the serum of patients with alcohol liver disease. Materials and Methods: The testing was performed on the serum of 38 patients with alcoholic fatty liver (26 males and 12 females aged 31-75). The total activity of ADH was determined by the colorimetric method. The activity of ADH I and ADH II, as well as ALDH, was determined by the spectrofluorometric method using fluorogenic specific substrates. The activity of isoenzymes of other classes was determined by spectrophotometric methods using substrates. Results: A statistically significantly higher ADH I activity was noted in the serum of patients with alcoholic fatty liver (4.45 mIU/L) compared to the control group (2.04 mIU/L). A statistically significant increase in the activity was also noted for the class II alcohol dehydrogenase isoenzyme (29.21 mIU/L, control group: 15.56 mIU/L) and the total ADH (1.41 IU/L, control group: 0.63 IU/L). Conclusions: The obtained results imply the diagnostic usefulness of the determination of AHD total, ADH I, and ADH II activity in the serum of patients with alcoholic fatty liver.
