ABSTRACT

Drug-associated thrombotic thrombocytopenic purpura and hemolytic uremic syndrome (TTP/HUS) has been recognized for several years. The most commonly implicated drugs are mitomycin-C, cyclosporine, quinine, and ticlopidine. As with idiopathic cases of TTP/HUS, basic science discoveries in the late 1990s now suggest that the likely mechanisms by which these agents lead to a thrombotic microangiopathy (TMA) include either an immune-mediated phenomenon involving the ADAMTS13 metalloprotease or direct endothelial toxicity. This article reviews the current understanding of the pathogenesis, the clinical and laboratory features, and the recommended treatments, prognosis, and outcomes of drug-associated TMA.
