The vast majority of cases of thrombotic thrombocytopenic purpura (TTP) are the result of acquired antibodies which inhibit the activity of the ADAMTS13 enzyme. Acquired TTP is more frequently seen in young females or in individuals with autoimmune disease. The development of antibodies against ADAMTS13 may also result from the administration or consumption of drugs and other substances. However, specific laboratory tests to identify the pathogenic mechanism of a particular drug may not be available, and the role of a potentially implicated drug or other ingested substance may not be clear. In this report we present 2 acquired TTP cases involving the consumption of a large amount of energy drink.
