[Acute immuno-allergic tubulo-interstitial nephritis due to amoxicillin confirmed by rechallenge].

Acute kidney injury is a common drug adverse reaction and may concerned antibiotics. We report a case of an acute renal failure due to amoxicillin occurring twice in the same patient. Two mechanisms have been described for amoxicillin, with an immuno-allergic origin observed in our case. The diagnosis, supported by kidney biopsy, was confirmed by rechallenge with this patient.
