Acute interstitial nephritis associated with loracarbef therapy.

We describe a biopsy-confirmed case of acute interstitial nephritis associated with the use of loracarbef in an 18-month-old boy, which resulted in end-stage renal failure. This complication has been documented with the use of beta-lactam antibiotics, and it seems likely the loracarbef was responsible for acute interstitial nephritis in this patient.
