Definition:
Chronic glomerulonephritis is the advanced stage of a group of kidney disorders, resulting in inflammation and slowly worsening destruction of internal kidney structures called glomeruli.
Alternative Names:
Glomerulonephritis - chronic; Chronic nephritis
Causes, incidence, and risk factors:
Chronic glomerulonephritis occurs when there is slow, progressive destruction of the glomeruli of the kidney, with progressive loss of kidney function. In some cases, the cause is found to be a specific attack to the body's immune system, but in most cases, the cause is unknown. Iit is generally thought that a still-unidentified abnormality of the immune system is to blame. Damage to the glomeruli affects the kidney's ability to filter fluids and wastes properly. This leads to blood and protein in the urine. This condition may develop after survival of the acute phase of rapidly progressive glomerulonephritis. In about one-quarter of people with chronic glomerulonephritis there is no prior history of kidney disease, and the disorder first appears as chronic kidney failure. Glomerulonephritis is among the leading causes of chronic kidney failure and end stage kidney disease. Causes include:
