Postinfectious Glomerulonephritis (PIGN)
Prognosis for Postinfectious Glomerulonephritis
Normal renal function is retained or regained by 85 to 95% of patients. Glomerular filtration rate (GFR) usually returns to normal over 1 to 3 months, but proteinuria may persist for 6 to 12 months and microscopic hematuria for several years. Transient changes in urinary sediment may recur with minor upper respiratory infections. Renal cellular proliferation disappears within weeks, but residual sclerosis is common. In 10% of adults and 1% of children, postinfectious glomerulonephritis evolves into Rapidly Progressive Glomerulonephritis (RPGN) .
