Purpura, Thrombotic Thrombocytopenic

Purpura, Thrombotic Thrombocytopenic
0.100 Biomarker disease BEFREE Recent studies on the relationship between UL-vWFMs and vWF-CPase, together with its autoantibody (inhibitor) have brought about a clear discrimination between thrombotic thrombocytopenic purpura and hemolytic uremic syndrome. 11843286 2002
Purpura, Thrombotic Thrombocytopenic
0.100 Biomarker disease BEFREE Recent advances now suggest that deficiency of a specific von Willebrand factor (VWF) cleaving protease promotes tissue injury in TTP. 12172456 2002
Purpura, Thrombotic Thrombocytopenic
0.100 Biomarker disease BEFREE These findings support the view that vWF proteolysis is critical in regulating vWF-platelet interaction and set the stage for improving the diagnosis and treatment of thrombotic thrombocytopenic purpura. 12395148 2002
Purpura, Thrombotic Thrombocytopenic
0.100 Biomarker disease BEFREE This observation led to the recognition that UL vWF multimers precipitate the thrombotic occlusion of arterioles, a feature that characterizes TTP. 12656756 2003
Purpura, Thrombotic Thrombocytopenic
0.100 Biomarker disease BEFREE Thrombotic thrombocytopenic purpura (TTP) is caused by the persistence of the highly reactive high-molecular-weight multimers of von Willebrand factor (VWF) due to deficiency of the specific VWF-cleaving protease (VWF-CP) ADAMTS13, resulting in microangiopathic disease. 12393505 2003
Purpura, Thrombotic Thrombocytopenic
0.100 Biomarker disease BEFREE The metalloprotease ADAMTS-13 cleaves von Willebrand factor (VWF), and is absent or severely reduced in the plasma of patients with thrombotic thrombocytopenia purpura (TTP). 14652658 2003
