Severity of COVID-19 linked to heparanase activity and heparan sulfate levels

Researchers at Radboud University Medical Center in the Netherlands reported an increase of heparanase activity and heparan sulfate levels in the plasma of patients with coronavirus disease (COVID-19), which was also associated with the severity of the condition – suggesting, in turn, potential treatment utility of low molecular weight heparins. The paper is currently available on the medRxiv* preprint server.
