Diffuse podocytopathy, including minimal change disease and primary focal segmental glomerulosclerosis, is a common cause of nephrotic syndrome in adults and children. It is increasingly recognized to be autoimmune-mediated associated with anti-nephrin and other emerging anti-slit diaphragm antibodies, and can recur in the kidney allograft. Immunofluorescence is routinely used in evaluation of kidney biopsies, and updates include those on fibrillar diseases, monoclonal staining, lupus-like staining, and use of antibody KM55 in IgA-dominant glomerulonephritis.
