Glomerulonephritis

Glomerulonephritis (GN) is often part of a multisystem disorder.

Edema and hypertension are signs of severe or chronic disease.

A kidney biopsy is the test for definitive diagnosis, although it is not required in all patients.

Treating the underlying disorder and managing hypertension and proteinuria is the mainstay of therapy.

Some patients may eventually need dialysis or transplant.

Regular, and sometimes frequent, monitoring of renal function is critical.

GN denotes glomerular injury and applies to a group of diseases that are generally, but not always, characterized by inflammatory changes in the glomerular capillaries and the glomerular basement membrane (GBM). The injury can involve a part or all of the glomeruli or the glomerular tuft. The most common GNs are immune-mediated.[1]Kidney Disease: Improving Global Outcomes (KDIGO) Glomerular Diseases Work Group.
