Secondary glomerular disease

Secondary glomerular diseases are those with an identifiable underlying or systemic cause, in contrast to primary diseases, where a localized or intrinsic renal pathology is present. Diabetic and hypertensive glomerulopathies are the most common forms of secondary glomerular disease, although kidney biopsy is not usually required for their diagnosis or management. More commonly, biopsy is required in cases of suspected glomerulonephritis, where a variety of histological lesions can be seen, all of which – including podocytopathy, membranous nephropathy and various forms of proliferative glomerulonephritis – have established secondary causes or associations.
