Özet

Thrombotic thrombocytopenic purpura (TTP) is a rare, dangerous, life-threatening disease characterized by microangiopathic hemolytic anemia and thrombocytopenia, along with organ dysfunction due to microangiopathy-related ischemia. Plasma exchange and steroids are used for initial treatment, and rituximab is often used in refractive patients. Caplacizumab, cyclophosphamide, and splenectomy are among other treatment options. It has been reported that bortezomib, a proteasome inhibitor, can be used in the management of refractory acquired TTP. Herein, we present a 16-year-old female patient who was monitored for acquired TTP and treated with high-dose steroids, plasma exchange, rituximab, cyclophosphamide, and N-acetylcysteine but developed renal, cardiac, gastrointestinal, and neurologic complications. The girl was then successfully treated with bortezomib, and she has been monitored in remission for 6 months. We consider that bortezomib is a beneficial treatment, especially in patients with refractory TTP.
