FIGURE 3

A 45-year-old male presents with cough, shortness of breath and fevers. He also complains of significant new lower extremity swelling and foamy urine. SARS-CoV-2 infection is confirmed and a 24-h urine reveals 15 g of proteinuria. His serum creatinine is 4.2 mg/dL. He is found to be positive for high-risk APOL1 genotype G1/G1. All serological workup is negative. A kidney biopsy reveals CG with ATI. This image reveals proliferation of glomerular epithelial cells over the collapsed segments of the capillary tuft . Some epithelial cells contain prominent intracytoplasmic protein reabsorption droplets (Jones methenamine silver stain, ×400).
