- Blood pressure medications are often needed to control high blood pressure. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are most commonly prescribed.
- Corticosteroids may relieve symptoms in some cases.
- Medications that suppress the immune system may also be prescribed, depending on the cause of the condition.
- You have disorders that are associated with an increased risk of glomerulonephritis
- You develop symptoms of glomerulonephritis
Glomerulonephritis is a type of kidney disease in which the part of your kidneys that helps filter waste and fluids from the blood is damaged.
Causes, incidence, and risk factors
Glomerulonephritis may be caused by specific problems with the body's immune system. Often, the precise cause of glomerulonephritis is unknown.
Damage to the glomeruli causes blood and protein to be lost in the urine.
The condition may develop quickly, with loss of kidney function occurring over weeks and months (called rapidly progressive glomerulonephritis).
In about a quarter of people with chronic glomerulonephritis there is no history of kidney disease and the disorder first appears as chronic renal failure.
The following increase your risk of developing this condition:
Many conditions are known to cause or increase the risk for glomerulonephritis, including:
Common symptoms of glomerulonephritis are:
Symptoms that may also appear include the following:
Chronic renal failure symptoms may gradually develop.
Other symptoms that may occur with this disease:
Signs and tests
Because symptoms develop gradually, the disorder may be discovered when there is an abnormal urinalysis during a routine physical or examination for unrelated disorders.
Glomerulonephritis can cause high blood pressure. It may only be discovered as a cause of high blood pressure that is difficult to control.
Later, signs of chronic kidney failure may be seen, including swelling (edema), polyneuropathy, and signs of fluid overload, including abnormal heart and lung sounds.
Imaging tests that may be done include:
Urinalysis and other urine tests include:
This disease may also affect the results of the following blood tests:
Treatment varies depending on the cause of the disorder, and the type and severity of symptoms. High blood pressure may be difficult to control, and it is generally the most important aspect of treatment.
Medicines that may be prescribed include:
A procedure called plasmapheresis may be used for some cases of glomerulonephritis due to immune-related causes. The fluid part of the blood containing antibodies is removed and replaced with intravenous fluids or donated plasma (without antibodies). Removing antibodies may reduce inflammation in the kidney tissues.
Dietary restrictions on salt, fluids, protein, and other substances may be recommended.
Persons with this condition should be closely watched for signs that they are developing kidney failure. Dialysis or a kidney transplant may eventually be necessary.
You can often ease the stress of illness by joining support groups where members share common experiences and problems.
If you have nephrotic syndrome and it can be controlled, other symptoms may also be controlled. If it can't be controlled, end-stage kidney disease may result.
Calling your health care provider
Call your health care provider if:
There is no specific way to prevent most cases of glomerulonephritis. Some cases may be prevented by avoiding or limiting exposure to organic solvents, mercury, and nonsteroidal anti-inflammatory drugs (NSAIDs).
