Abstract:
To explore the relationship between clinical findings and pathological changes of IgA nephropathy (IgAN), 37 children with IgAN were undertaken clinical classification and renal-pathological comparison including glomerulus change, renal tubule-interstitial change and immunopathology. The results showed that there were 18 (49%) cases with hematuria, 14 (38%) cases with nephrotic syndrome, 3(8%) cases with both of hematuria and proteineuria, and 2 (5%) cases with nephritic syndrome in the clinical classification. 54% of cases with glomerulus changes was as class III. No significant relationship was found between clinical classification and glomerulus changes. There were 24 cases with renal-tubule interstitial changes and 7 cases with hematuria. 43% of them were classified as class I and 57% as class II.All cases with nephrotic syn-drome developed renal tubule-interstitial change. 78% (11 cases) of them were as class II and 22% (3 cases) as class III. Besides, 2 of 3 cases with both of hematuria and proteineuria and 1 of 2 cases with nephritic syndrome also manifested renal tubule-interstitial change. There were four phenotypes were observed in immunopathology including 16 cases of them as IgA, 6 cases as IgAG, 10 cases as IgAM and 5 cases as IgAGM, respectively. 66% of cases with hematuria was found as IgA and 50% of cases with nephrotic syndrome as IgAM. It is concluded that hematuria can be a main clinical finding in both of IgAN and nephrotic syndrome. Glomerulus changes is usually not correlated with clinical classification. There is a significant renal tubule-interstitial change in cases with nephrotic syndrome. Hematuria is usually as IgA and nephrotic syndrome as IgAM in immunopathology.
