A review, with 45 references Liver is a frequent target for drug-induced hepatitis. They can be classified in two categories: the hepatitis in which the drug or a metabolite reach a vital target in the cell and the hepatitis in which the drug triggers an adverse immune response directed against the liver. We will discuss essentially this second kind of disease. They have key clin. features such as the low frequency, the dose independence, the delay between the beginning of drug intake and the triggering of the disease, the shortening of the delay upon rechallenge and very often the presence of autoantibodies in the serum of the patients. Such signs were found in hepatitis triggered by drugs such as halothane, tienilic acid, dihydralazine, anticonvulsants. They will be taken as examples to show the recent progress in the understanding of the mechanisms leading to the disease. It has been postulated that the drug is metabolized into a reactive metabolite binding to the enzyme which generated it; therefore the neoantigen might trigger an immune response characterized by the production of antibodies recognizing the native and or the modified protein. Most of these steps were proven in the cases of halothane, tienilic acid and dihydralazine. Several points seem important in the development of the disease: the equilibrium between toxication and detoxication pathways, the nature and amount of neoantigen, the individual immune response. However, many points remain unclear: for instance, the reason for the very low frequency of this kind of disease; the precise mechanism of the adverse immune response; the risk factors for developing such adverse reactions. Efforts should be made to better understand the mechanisms of this kind of disease: for instance, an animal model, tests to identify drugs at risk for such reactions, the role of these drugs in the processing of P450s and the processing of the neoantigens for their presentation to the immune system.
