Thrombotic Microangiopathy Syndrome in a Basic Underwater Demolition/SEAL Student.

Abstract

Thrombotic microangiopathy (TMA) syndromes represent a spectrum of illnesses that share common clinical and pathologic features of microangiopathic hemolytic anemia, thrombocytopenia, and organ injury from pathologic small-vessel thrombosis. At least nine primary TMA syndromes have been described and classified based on common probable etiologies, diagnostic criteria, and treatments. The most recognized of the TMA syndromes include thrombotic thrombocytopenic purpura (TTP) and hemolytic-uremic syndrome (HUS). Advanced laboratory techniques are required to distinguish between these syndromes; however, all patients should initially be treated with plasma exchange for presumed ADAMTS13 deficiency-mediated TMA. The authors present a case of a TMA syndrome in a Navy SEAL (Sea, Air, Land) candidate.
