Collapsing glomerulopathy in a COVID-19 patient

The first available reports indicate that renal involvement is relatively frequent in patients with novel coronavirus disease 2019 (COVID-19) due to the emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Up to 43% of patients present with proteinuria (including 10% with heavy proteinuria), 11% with hematuria, and 3.5% to 5% with acute kidney injury.1,2 Both proteinuria and acute kidney injury are associated with increased mortality.1 However, the exact mechanisms underlying renal injury in patients with COVID-19 are unclear as renal pathology data are lacking.
