Elevated biomarker for blood vessel damage found in all children with SARS-CoV-2

(Children's Hospital of Philadelphia) Researchers at Children's Hospital of Philadelphia (CHOP) have found elevated levels of a biomarker related to blood vessel damage in children with SARS-CoV-2 infection, even if the children had minimal or no symptoms of COVID-19. They also found that a high proportion of children with SARS-CoV-2 infection met clinical and diagnostic criteria for thrombotic microangiopathy (TMA).
