Introduction

AKI in patients with COVID-19 may be due to ATI from hemodynamic instability or inflammatory responses. We present two cases of CSG and ATI in patients admitted for COVID-19

Case Description

Case 1 25-year-old black obese female admitted with fever, cough, dyspnea and serum creatinine of 1.4 mg/dL, discharged next day with home quarantine. Re-admitted 26 days later due to nausea, fatigue, and bilateral foot swelling. Serum creatinine 28 mg/dl and urine protein to creatinine ratio (uPCR) of 10.4 g/g

Case 2 42-year-old black female with hypertension, diabetes mellitus admitted with fever, dyspnea, cough, and diarrhea. Patient found to have diabetic ketoacidosis, serum creatinine 12.7 mg/dl. She developed deep vein thrombosis and pulmonary embolism and uPCR 15.4 g/g. She was started on hemodialysis

Kidney biopsy showed global and segmental capillary collapse with a variable degree of sclerosis and severe renal tubules injury. Electron microscopy showed spherical structures in the podocytes, endothelial cells, and tubular epithelium similar to Coronavirus particles

Discussion

Our experience above is part of a growing literature describing the direct visualization of SARS-CoV-2 in causing ATI and CSG. Pathogenetic pathways remain to be elucidated
