Reversible acute renal failure induced by indomethacin

Area of Science:

• Nephrology
• Pharmacology

Background:

• Chronic pyelonephritis is a serious kidney condition.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for pain and inflammation.

Observation:

• A patient with chronic pyelonephritis developed acute renal failure during indomethacin therapy.
• Urinary prostaglandin E2 levels decreased significantly during treatment.

Findings:

• Indomethacin therapy was associated with acute renal failure.
• Discontinuation of indomethacin led to recovery of renal function.
• Urinary prostaglandin E2 levels normalized after drug withdrawal.

Implications:

• Prostaglandins are vital for maintaining normal kidney function.
• NSAIDs, including indomethacin, may harm patients with pre-existing kidney disease.
• Caution is advised when prescribing NSAIDs to individuals with renal impairment.
