Hemolytic Uremic Syndrome Following Taipan Envenomation with Response to Plasmapheresis

We report a case of hemolytic uremic syndrome (HUS) in a 33 year old male who was bitten by a taipan, with apparent massive envenomation. The microangiopathic hemolytic anemia (MAHA) and thrombocytopenic aspects of his HUS appeared to respond to plasmapheresis, but his anuric renal failure persisted. He also had prolonged severe muscular paralysis which gradually began to resolve over the course of two weeks. At this point he suffered a cardiac arrest sustaining severe and subsequently fatal hypoxic brain injury. This case raises the possibility that the taipan venom may have induced HUS by damaging the renal endothelium. His cardiac arrest was not apparently related to his HUS.
