Age-related character of glomerular lesions in IgA nephritis. (2). Histopathological peculiarity in childhood onset.

Abstract

Histopathological analysis was performed in the first renal biopsy specimens of patients over and under 10 yrs of IgA nephritis. They were divided clinically into two groups, the one with remission and the other with prolonged disease state respectively. Increased mesangial sclerosis, frequent occurrence of segmental glomerular lesions and tubulointerstitial change were significantly evident in the group with prolonged disease state. It is suggested that similar glomerular events are progressing in IgA nephritis which is carried over to adult age.
