Pathogenesis and diagnosis of thrombotic thrombocytopenic purpura

Thrombotic thrombocytopenic purpura (TTP) is a rare and life-threatening thrombotic microangiopathy characterized by microangiopathic hemolytic anemia, consumption thrombocytopenia, and organ injury. TTP pathophysiology is based on a severe ADAMTS13 deficiency, the specific von Willebrand factor (VWF)-cleaving protease. Expert opinion: Differential diagnosis of TTP may be challenging and ADAMTS13 investigations are needed. ADAMTS13 conformation could be a promising parameter for TTP diagnosis and prognosis in the coming years. Plasma therapy remains the first-line treatment of the acute phase of TTP.
