Postinfectious glomerulonephritis is the most common cause of nephritic syndrome and acute renal failure in children. This condition usually results from a recent group A streptococcal infection and the diagnosis is based on clinical suspicion and laboratory data. This case describes a child with new onset hypertension and a past history of untreated streptococcal pharyngitis. Treatment is supportive and recent reviews demonstrate that antibiotic therapy directed at the infection does not modify the course of glomerulonephritis.
