Background Definition and classification Inflammation of the glomeruli. This page discusses primary glomerulonephritides, but glomerular disease can also be secondary to diabetes and multi-system autoimmune or infiltrative diseases. Can be classified by whether they typically present with nephrotic syndrome – minimal change disease, membranous GN, membranoproliferative GN, FSGS – or haematuria/nephritic syndrome – IgA nephropathy, post-streptococcal GN, rapidly progressive GN. However, presentation is often non-specific and asymptomatic. Presentation Can be an incidental finding in an asymptomatic individual e.g. with hypertension, proteinuria or haematuria on dipstick, abnormal renal function test, anaemia. Symptomatic presentations include oedema (nephrotic syndrome), frank haematuria, or generally unwell (uraemia, anaemia). Management See  chronic kidney disease (CKD)  and/or  acute kidney injury (AKI)  for general management of renal impairment. BP control (SBP ...
