Abstract Postinfectious glomerulonephritis is rarely presented as rapidly progressive glomerulonephritis in children; the prevalence is approximately 1-3 %. [ncbi.nlm.nih.gov]

Ten presented as a nephritic syndrome, seven as a rapidly progressive GN, three as acute renal failure, one as chronic renal failure, and one as a nephrotic-nephritic syndrome. The C3 fraction of complement was low in 21 cases. [pesquisa.bvsalud.org]

• Hematuria

  This disorder equally affected all ages, both genders, and typically presented with hematuria and proteinuria. In both the short and long term, renal function remained stable in the majority of patients with native kidney disease. [ncbi.nlm.nih.gov]

Most children have acute onset of renal failure; initial treatment involves corticosteroids and immunosuppressive therapy. Early diagnosis improves prognosis. [ncbi.nlm.nih.gov]

Early diagnosis improves prognosis. In recent years, an entity known as "C3 glomerulopathies" has been described, presenting characteristics that overlap. [ncbi.nlm.nih.gov]
