ABSTRACT
PURPOSE: This study was performed to determine the natural history of histologically confirmed IgA nephropathy in pediatric patients who presented with hematuria and proteinuria. PATIENTS AND METHODS: We reviewed the clinical course of 57 patients diagnosed with IgA nephropathy at the age of 15 years or younger from 1981 to 2000. All patients presented with hematuria or minimal proteinuria( or =40 mg/m2/day), hypertension, and chronic renal failure. RESULTS: The mean age at presentation was 9.5+/-2.8 years(4 to 15 years) and 42(74%) were male. Isolated gross hematuria was observed in 20 patients(35%), microscopic hematuria in 3(5%), minimal proteinuria in 4(7%), both gross hematuria and minimal proteinuria in 15(26 %), and both microscopic hematuria and minimal proteinuria in 15(26%). During a median follow-up of 7.0+/-3.5 years, 38(67%) had complete resolution of hematuria and proteinuria, 12(21%) had persistently abnormal urinalysis without development of adverse events. Only 7(12%) developed adverse events:4(7%) developed severe proteinuria, 1(2%) became hypertensive, and 2(3%) developed impaired renal function. By univariate analysis using the chi-square test, the age at presentation(>10 years)(P<0.01) and poor histological classes of the Lee or Haas classification at onset(P<0.05) were significantly correlated with adverse events, whereas sex and clinical signs at onset were less concordant. CONCLUSION: We can conclude that the prognosis of IgA nephropathy diagnosed in early childhood is better and a good correlation exists between the clinical manifestations of this disease and the histological classes.
