What is Rapidly Progressive Glomerulonephritis?

Rapidly Progressive Glomerulonephritis
Renal biopsy findings in a 60-year-old patient with pauci-immune extracapillary-proliferative glomerulonephritis due to IgG kappa multiple myeloma. (A) Biopsy before bortezomib treatment (200×, PAS) showing a proliferating glomerular crescent. The tubulointerstitial space appears to be normal. Polymorphonuclear leucocytes within the glomerular tuft. No infiltrates. (B) Biopsy after bortezomib treatment (200×, PAS) showing sclerosing glomeruli and sclerosing crescents, interstitial fibrosis and tubular atrophy with only scarce inflammatory infiltrates. The majority of glomeruli showed normal appearance. Monoclonal gammopathy-associated pauci-immune extracapillary-proliferative glomerulonephritis successfully treated with bortezomib: Grundmann F, Witthus M, Göbel H, Kisner T, Siewert R, Benzing T, Kurschat CE - Clinical kidney journal (2013).

Rapidly progressive glomerulonephritis is a disease of the glomeruli characterized by rapid loss of function of the kidney.

What is the Pathology of Rapidly Progressive Glomerulonephritis?

The pathology of rapidly progressive glomerulonephritis is:

-Etiology: The cause of rapidly progressive glomerulonephritis is infections, multisystemic disease, drugs and toxic agents.

-Genes involved: Unknown. 

-Pathogenesis: The sequence of events that lead to rapidly progressive glomerulonephritis, the antigen formed against the GBM antibodies lead to increased damage to the kidney.
