THE PROGNOSIS of acute glomerulonephritis in children remains controversial. Manyauthors expect only 60%-70% of such patients to recover1-4; whereas others anticipate that 80%-90% will heal.5-8 These discrepancies aredifficult to evaluate because diagnostic criteria may not have been given,9-12 the number of cases may be small,13-16 or the period of followup may be short.2,17-19 A review of our experience at the Childrens Hospital of Los Angeles was undertaken to determine if the causes of these discrepancies could be eliminated or minimized.
