Acute Interstitial Nephritis
Acute interstitial nephritis is a kidney disorder in which the kidneys become unable to filter waste materials and fluid properly. This is a potentially serious condition that requires care from your doctor.
Acute interstitial nephritis can be caused by:
- Infections such as:
Particular medications (accounts for 85% of all cases)
- Certain antibiotics
- Anti-ulcer drugs
- Nonsteroidal anti-inflammatory drugs
- Certain diuretics
- Conditions that affect the immune system (eg, ]]>lupus]]> )
A risk factor is something that increases your chance for getting a disease or condition. The following risk factors increase your chance of developing acute interstitial nephritis. If you have any of these risk factors, tell your doctor:
- In adults: drug / medication use
- In children: infection
If you experience any of these symptoms do not assume it is due to acute interstitial nephritis. These symptoms may be caused by other, less serious health conditions. If you experience any one of them, see your physician.
- Decrease in urine output
- Blood in urine
- Loss of appetite
- Aching joints

Talk with your doctor about the best treatment plan for you, which will depend on the cause of your acute interstitial nephritis. Treatment options include the following:
If medications are the cause of your interstitial nephritis, your doctor may have you stop taking medications or prescribe a different one.
Antibiotics are used to treat an infections and drugs such as corticosteroid or cyclophosphamide medications may also be used to help treat interstitial nephritis. Usually a kidney biopsy is done to confirm the diagnosis prior to starting corticosteroid or cyclophosphamide.
Some people with interstitial nephritis need dialysis]]> , in which a machine does the work of your kidneys to purge waste.
