Interstitial nephritis

Alternative Names

Tubulointerstitial nephritis; Nephritis - interstitial; Acute interstitial (allergic) nephritis

Treatment

Treatment focuses on treating underlying causes and relieving symptoms. Avoiding the suspect medications may cause the symptoms to go away quickly.

Dietary restriction of sodium (salt) and fluid may control swelling and hypertension. Dietary restriction of protein may be needed to control azotemia (accumulation of nitrogenous waste products in the blood) associated with acute renal failure.

If dialysis is necessary, it usually is required for only a short time.

Corticosteroids or anti-inflammatory medications may be of benefit in some cases.

Outlook (Prognosis)

Most often, interstitial nephritis is anacute but short-term disorder. On rare occasions it may cause permanent damage including chronic renal failure.

Possible Complications

• Acute renal failure
• Chronic renal failure

When to Contact a Medical Professional

Call your health care provider if symptoms indicate interstitial nephritis may be present.

If you have interstitial nephritis, call if new symptoms develop, especially decreased alertness or decrease in urine output.
