title: Celecoxib-induced acute interstitial nephritis.
abstract: Data about the nephrotoxicity of selective cyclooxygenase-2 inhibitors are still evolving. Acute interstitial nephritis is a well-described complication of therapy with nonselective nonsteroidal anti-inflammatory drugs. We report a case of biopsy-proven acute interstitial nephritis in a 73-year-old diabetic woman, who had taken celecoxib for more than 1 year before presentation. She presented with clinical findings of subnephrotic proteinuria and acute renal failure that required dialysis. She recovered renal function with cessation of celecoxib therapy after 2 weeks. Other medications were reintroduced safely, without recurrence of renal failure. A kidney biopsy specimen showed acute interstitial nephritis with a prominent eosinophilic infiltrate in the interstitium. This case documents the occurrence of acute interstitial nephritis with celecoxib and emphasizes the need for continued vigilance and care in use of cyclooxygenase-2 inhibitors in high-risk patients.
