Acute post streptococcal interstitial nephritis in an adult and review of the literature.

While glomerular lesions are a recognized sequel to infection with group A beta haemolytic streptococci, literature on primary tubular lesions, as remote effects of streptococcal infection, is scanty. A case of interstitial nephritis in a 29-year-old woman following streptococcal sore throat is described. This adult admitted with tonsillitis developed acute renal failure from acute interstitial nephritis and subsequently had full recovery of renal function. Acute interstitial nephritis should be included in the differential diagnosis of patients with streptococcal infections who develop acute renal failure.
