Acute liver failure and encephalopathy (Reye's syndrome?) during salicylate therapy

A case of hepatotoxicity and encephalopathy (Reye's syndrome?) associated with salicylate therapy is presented and the aetiology of this syndrome is discussed. Hepatotoxicity developed with salicylate serum concentrations not exceeding therapeutic serum levels. The importance of controlling serum salicylate concentration and transaminase activity particularly during the first fourteen days of therapy is emphasized.
