Atypical Hemolytic and Uremic Syndrome Triggered by Infection With SARS-CoV2

Atypical hemolytic and uremic syndrome (aHUS), as a form of thrombotic microangiopathy, (TMA) is characterized by a genetic or acquired dysregulation of complement activation, leading to endothelial cell lesions and thrombosis of the small vessels, hemolysis, thrombocytopenia, and acute kidney injury.S1 Here, we report 2 cases of complement mediated aHUS triggered by infection with SARS-CoV-2.
