Summary
Sulpyrine, a common Japanese medication, may cause acute kidney injury. This case report links sulpyrine use to acute tubulointerstitial nephritis (ATIN) and subsequent renal failure.
Area of Science:
- Nephrology
- Pharmacology
- Toxicology
Background:
- Sulpyrine is a widely prescribed medication in Japan.
- Acute tubulointerstitial nephritis (ATIN) is a significant cause of acute kidney injury.
- Drug-induced ATIN is a critical diagnostic consideration.
Observation:
- A patient developed acute renal failure.
- The patient had been using sulpyrine.
- Renal biopsy revealed features consistent with ATIN.
Findings:
- The clinical presentation and histological findings strongly suggest sulpyrine-induced ATIN.
- This adverse drug reaction led to severe acute kidney injury.
Implications:
- Clinicians should consider sulpyrine as a potential cause of ATIN in patients presenting with acute kidney injury.
- This case highlights the importance of medication history in diagnosing drug-induced renal diseases.
- Further pharmacovigilance may be warranted for sulpyrine regarding renal toxicity.
