CD79A and IgA glomerulonephritis: The above study found some difficulty in differentiating IgA-dominant postinfectious glomerulonephritis when the presentation is atypical from other glomerulonephritis, especially primary IgA nephropathy, which can have similar light microscopy and immunofluorescence manifestations, but the treatment options for the two are different, and the prognosis of patients with IgA-dominant postinfectious glomerulonephritis is often reported worse [15–17].
