Legionnaires' disease and acute renal insufficiency: report of a case and review of the literature.

We report the case of a 73-year-old man, who developed acute renal failure in association with a Legionella pneumophila serotype 1 pneumonia. Renal biopsy revealed a tubulointerstitial nephritis. Treatment with erythromycin, rifampicin and haemodialysis resulted in a clinical resolution of the pulmonary and renal syndromes.
