Role of Plasminogen-Activator Inhibitor Type 1 in the Pathogenesis and Outcome of the Hemolytic Uremic Syndrome

Abstract

Our studies suggest that PAI-1 is the circulating inhibitor of fibrinolysis in the hemolytic uremic syndrome. Normalization of plasma PAI-1 levels (e.g., by peritoneal dialysis) is correlated with improvement in renal function. However, the possibility that increased plasma levels of PAI-1 are either causes or effects of the hemolytic uremic syndrome is not unequivocally established by these studies.
