[Streptococcal infection, acute kidney failure and interstitial nephritis].

The relationship between streptococcal infection and renal disease has been object of multiple studies. Streptococcal infection may induce acute glomerulonephritis or interstitial nephritis. We report a patient with a streptococcal infection who developed acute renal failure. The renal biopsy showed an acute interstitial nephritis, with an interstitium infiltrate with a significant number of eosinophils. We review the causes of acute renal failure associated with streptococcal infection, specially acute interstitial nephritis.
