ABSTRACT
Purpose : Clinical manifestations and pathologic findings of thin glumerular basement membrane disease, recognized as a common underlying disease of benign, familaiar and asymptomatic hematuria has not been reported systemically in Korera. We analyzed clinical and pathologic findings of patients who were diagnosed as thin glomerular basement membrane disease
Methods : We analyzed clinical and pathologic findings of twenty-six patients who were diagnosed as thin glomerular basement membrane disease by renal biopsy among who complained asymptomatic hematuria from 1990 to 2000.
Results : The subjects were aged 9.4${pm}$3.2 (3.0-15.8) years-old at onset of hematuria, and 11.1${pm}$2.2 (4.7-16.3) years-old at renal biopsy. Sexual discrepancy was more common in girls (eight boys and eighteen girls). A family history of hematuria was found in 8 patients(30.7$%$). Major clinical manifestation on admission was microscopic hematuria according to the findings of 3case(11.5$%$) of gross hematuria, 23cases(88.5$%$9) of microscopic hematuria, and 1 case(3.8$%$) of proteinuria. Microscopic hematuria persisted in all cases. Kidney biopsy showed few changes by light microscopy, but IgM, C3 and fibrinogen deposit in mesangium was found by immunofluorescent microscopy in a few cases. Electron microscopic findings have revealed thinning of the glomerular basement membrane varied from 180.9${pm}$35.8nm.
Conclusion : Thin glomerular basement membrane disease might be a common cause of microscopic hematuria of children and family history was revealed in about 30$%$. Clinical progression was good in majorities.(J. Korean Soc Pediatr Nephrol 5 : 1-8, 2001)
