Second attacks of acute glomerulonephritis

The cases of 12 Negro children with two clinically and histologically similar attacks of acute glomerulonephritis are reported. The absence of clinical and histologic evidences of chronic glomerulonephritis during a period of 6 to 108 months of follow-up study is emphasized. Lobular mesangial hyperplasia constituted the major persistent histologic abnormality; focal thickening of Bowman's capsule was less frequently observed.
