Renal dysfunction resulting from NSAIDs

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a common cause of acute renal failure. The clinical presentation differs from that of interstitial nephritis due to antibiotic use: proteinuria is much more common in NSAID-induced nephritis, while eosinophilia, eosinophiluria, fever and rash are more common in antibiotic-related nephritis. Tubulointerstitial disease associated with NSAID use is more common in women than in men and is more frequently seen in the elderly. Because no prospective study of treatment for NSAID-induced acute tubulointerstitial nephritis has been performed, the efficacy of steroid therapy remains uncertain.
