Abstract
A variety of medicinal drugs, with a molecular weight of less than 1,000 dalton, can elicit systemic hypersensitivity reactions and autoimmune disorders in susceptible individuals at low incidence. Attempts to induce autoimmune disorders with drugs in experimental animals have often been unsuccessful, but a few reproducible models of drug-induced autoimmune disease are available. The induction of autoimmune reaction is, however, highly strain-specific, both in rats and mice, and is clearly determined by the immunogenetic background. A major challenge for the development of predictive toxicity testing methods and risk assessment represents the analysis of the contribution of individual factors to the development of disease. Therefore, it will be difficult to develop assays for regulatory purposes which allow hazard identification of autoimmunity-inducing drugs.
