THROMBOTIC MICROANGIOPATHY ASSOCIATED WITH OPANA ER INTRAVENOUS ABUSE A Case Report.

Thrombotic microangiopathy is characterized by endothelial changes and microvascular stenosis. Several entities such as pregnancy, infection, connective tissue diseases, and drugs are associated with secondary thrombotic microangiopathy. Recently, new reformulation of Opana ER had been associated with thrombotic microangiopathy when injected intravenously. Here, we report the case of a 37-year-old man who developed renal failure and hemolytic anemia secondary to Opana ER intravenous abuse. Renal biopsy pathology was consistent with thrombotic microangiopathy likely caused by Opana ER intravenous abuse.
