title: Drug-induced liver disease.
abstract: The year 2002 saw a warning from the US Food and Drug Administration not to use the diet agent, Lipokinetix, and brought to light a few new agents as potential hepatotoxins. Numerous other reports confirmed the hepatotoxicity of several previously described agents. Refinements in causality assessment remain an important aspect in defining drug-induced liver disease and proposed new upper limits of normal for alanine aminotransferase that are lower than most laboratories currently report may require rethinking our definition of "normal liver function tests." Chronic viral hepatitis B and C remain important risk factors for antiretroviral-induced liver injury in patients co-infected with the human immunodeficiency virus and in patients receiving antituberculosis therapy. Acetaminophen retains its status as the most common cause of acute drug-induced liver failure in the United States and in many other countries. Several papers addressed the issue of accidental versus intentional overdoses, the role of alcohol consumption as a risk factor, and newer aspects of treating and preventing acetaminophen injury to the liver. Finally, the use of potentially hepatotoxic medications in patients with underlying liver disease continues to be a controversial topic and a rational approach to the use of such drugs in this setting is provided.
