Abstract

This case report details the presentation of a 24-year-old male presenting with headache, palpitations, gingival bleeding, and pallor. The ultimate diagnosis of thrombotic thrombocytopenic purpura (TTP) is a rare but life-threatening condition which is typically hallmarked by thrombotic microangiopathy (TMA) and dysfunctional ADAMTS13 enzymatic activity. This patient displayed classically described findings, including marked anemia, thrombocytopenia, and acutely elevated creatinine as well as a brief period of newly onset word-finding difficulty while in the emergency department. His diminished ADAMTS13 activity level (<5%) and the presence of autoantibodies against ADAMTS13 confirmed a diagnosis of TTP. Fortunately, the patient's outcome was favorable after treatment with plasmapheresis, prednisone, and rituximab. This case report provides a review of the clinical presentation, diagnostic criteria, potentially confounding differential diagnosis, and expected course of treatment for patients with TTP.

Topics: Thrombotic thrombocytopenic purpura (TTP), ADAMTS13, anemia.
