Teaching points

1.Although acute tubular injury is the most common kidney pathology seen with SARS-CoV-2 infection, ANCA-associated glomerulonephritis can be associated with COVID-19.

2.Patients who developed ANCA glomerulonephritis responded well to immunosuppressive agents including rituximab, and none of these patients had deterioration of SARS-CoV-2−related disease.

3.ANCA vasculitis should be considered as a differential diagnosis of COVID-19−related acute kidney injury, and may be effectively managed with use of immunosuppressants despite underlying infection.

ANCA, antineutrophilic autoantibody; COVID-19, coronavirus disease 2019; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
