Abstract
The serum aspartate transaminase, 2 h post-prandial bile acids and the aminopyrine breath test were measured in 14 alcoholics with histologically proved minimal liver damage. A raised aspartate transaminase value was found in 64% (9/14) of the patients and was the commonest abnormality found. In 3 patients all 3 tests were normal. Six patients stopped abusing alcohol and, when reassessed a mean of 33 days later, showed significant changes in the mean aspartate transaminase value and the mean value for the aminopyrine breath test. There was no significant change in the mean post-prandial bile acids value. The remaining 8 patients continued to drink alcohol and, when reassessed at a mean of 118 days, showed no significant change in any of these indices. Of the methods assessed, the serum aspartate transaminase appeared to be the most useful for detecting and monitoring patients with minimal alcoholic liver disease. All 3 tests failed to detect an unacceptably high percentage of the patients, and liver biopsy therefore remains a more certain diagnostic method.
