    Abstract:
    In a retrospective analytical study involving 98 children with primary glomerulonephritis who were seen by us at our hospital during a 2-year period from 1984 through 1985 and who had renal biopsy performed previously, attempts were made to correlate pathological findings with both clinical findings and prognosis. The results are summarized as follows: 1) Of 87 patients with asymptomatic chronic glomerulonephritis, glomerular findings were those of minimal change lesion, mesangial proliferative nephritis, MPGN, membranous nephropathy and FGS or sclerosing nephritis in 29.9%, 51.7%, 13.8%, 1.1% and 3.5%, respectively. Among the other 11 patients in whom the diagnosis was made after manifesting the nephritic symptoms, minimal change was noted less frequently and MPGN was detected more frequently than in the aforementioned asymptomatic group. IgA nephropathy was estimated to account for 44.2% of cases of asymptomatic chronic nephritis. 2) Mild mesangial proliferation was observed relatively frequently and severe mesangial proliferation or MPGN rather infrequently in hematuria cases without proteinuria while in those with severe proteinuria minimal change lesion was uncommon and severe mesangial proliferative changes, MPGN or FGS were relatively frequent. 3) In 22 patients with IgA nephropathy and 11 with non-IgA nephritis the severity of glomerular changes was related to the intensity of proteinuria at the time of renal biopsy. 4) A 3 to 5 years' follow-up study of patients with mesangial proliferative nephritis inclusive of IgA nephropathy disclosed that 26-28% of patients became free from urinary abnormalities, 27-37% had persistent hematuria without proteinuria and 24-32% still had proteinuria of 2 plus or above. Patients with milder glomerular changes had a definitely better prognosis than those with severe glomerular lesions.
