[Acute renal damage caused by ampicillin. Description of a case].

Approximately one week after a cycle of antibiotic therapy using ampicillin for pulmonary inflammation, an 82-year-old woman developed symptoms of acute renal insufficiency reminiscent of nephrotic syndrome. Symptoms were completely reversible and normal renal function was recovered (even after 14 months of follow-up). The Authors conclude by attributing this to acute tubulo-interstitial nephropathy due to hypersensitivity to ampicillin.
