title: Hepatic enzymes' level during chronic use of anticonvulsant drugs.
abstract: We studied retrospectively 894 adult epileptic patients treated during the period from 1983 to 1992. Hepatic enzymes abnormal values were seen in 49% (n = 438). In 22.3% (n = 200), at least 2 enzyme levels in different moments were altered. They were divided in three groups: GI with alterations at transaminases (3%, n = 6), GII with alterations at GGT and AP enzymes (72%, n = 144) and GIII with alterations in both groups (25%, n = 50). No patient developed clinical symptoms of liver disease. The increase of gamma-glutamil-transferase (GGT) and alkaline phosphatase (AP) levels is frequent and not necessarily pathological. Slight increase of transaminases can occur with no clinical correlation. The routine screening of hepatic enzymes level during the chronic use of anticonvulsivant drugs in adults has a questionable value.
