<prompt> The prognosis of rapidly proliferating glomerulonephritis Crescentic GN depends upon which of the following factor?Number of crescentsSize of crescentsShape of crescentsCellularity of crescents  <response>: The prognosis of Crescentic glomerulonephritis can be roughly related to the number of crescents, patients with crescents fewer than 80 of the glomeruli have a slightly better prognosis than those with higher percentage of crescents. Other factors affecting prognosis are: Clinical Pathology Age at onset of disease Extent of crescentic involvement normal glomeruli Infectiousdrug etiology Nature of crescentcellular, fibrocellular, fibrous Renal function at discoveryoliguria, dialysis dependence Extent of glomerulosclerosis SerologyANCA, anti GBM, dual antibody Chronic tubulointerstitial lesions Genetics HLA Disruption of Bowmans capsule Ref: Treatment of Primary Glomerulonephritis edited by Claudio Ponticelli.
