Learn About Poststreptococcal Glomerulonephritis

What is the definition of Poststreptococcal Glomerulonephritis?

Poststreptococcal glomerulonephritis (GN) is a kidney disorder that occurs after infection with certain strains of streptococcus bacteria.

What are the alternative names for Poststreptococcal Glomerulonephritis?

Glomerulonephritis - poststreptococcal; Postinfectious glomerulonephritis

What are the causes of Poststreptococcal Glomerulonephritis?

Poststreptococcal GN is a form of glomerulonephritis. It is caused by an infection with a type of streptococcus bacteria. The infection does not occur in the kidneys, but in a different part of the body, such as the skin or throat. The disorder may develop 1 to 2 weeks after an untreated throat infection, or 3 to 4 weeks after a skin infection.

It may occur in people of any age, but it most often occurs in children ages 6 through 10. Although skin and throat infections are common in children, poststreptococcal GN is rarely a complication of these infections. Poststreptococcal GN causes the tiny blood vessels in the filtering units of the kidneys (glomeruli) to become inflamed. This makes the kidneys less able to filter the blood to create urine.

The condition is not common today because infections that can lead to the disorder are treated with antibiotics.

Risk factors include:

  • Strep throat
  • Streptococcal skin infections (such as impetigo)
What are the symptoms of Poststreptococcal Glomerulonephritis?

  • Decreased urine output
  • Rust-colored urine
  • Swelling (edema), general swelling, swelling of the abdomen, swelling of the face or eyes, swelling of the feet, ankles, hands
  • Visible blood in the urine

What are the current treatments for Poststreptococcal Glomerulonephritis?

There is no specific treatment for this disorder. Treatment is focused on relieving symptoms.

  • Antibiotics, such as penicillin, will likely be used to destroy any streptococcal bacteria that remain in the body.
  • Blood pressure medicines and diuretic drugs may be needed to control swelling and high blood pressure.
  • Corticosteroids and other anti-inflammatory medicines are generally not effective.

You may need to limit salt in your diet to control swelling and high blood pressure.

What is the outlook (prognosis) for Poststreptococcal Glomerulonephritis?

Poststreptococcal GN usually goes away by itself after several weeks to months.

In small number of adults, it may get worse and lead to long-term (chronic) kidney failure. Sometimes, it can progress to end-stage kidney disease, which requires dialysis and a kidney transplant.

What are the possible complications of Poststreptococcal Glomerulonephritis?

Health problems that may result from this disorder include:

  • Acute renal failure (rapid loss of kidneys' ability to remove waste and help balance fluids and electrolytes in the body)
  • Chronic glomerulonephritis
  • Chronic kidney disease
  • Heart failure or pulmonary edema (fluid buildup in the lungs)
  • End-stage renal disease
  • Hyperkalemia (abnormally high potassium level in the blood)
  • High blood pressure (hypertension)
  • Nephrotic syndrome (group of symptoms that include protein in the urine, low blood protein levels in the blood, high cholesterol levels, high triglyceride levels, and swelling)
When should I contact a medical professional for Poststreptococcal Glomerulonephritis?

Contact your health care provider if:

  • You have symptoms of poststreptococcal GN
  • You have poststreptococcal GN, and you have decreased urine output or other new symptoms
How do I prevent Poststreptococcal Glomerulonephritis?

Treating known streptococcal infections may help prevent poststreptococcal GN. Also, practicing good hygiene such as washing hands often prevents the spread of the infection.
