Which type of glomerular damage is seen in Goodpasture syndrome?

• A. Diffuse glomerulosclerosis
• B. Membranous nephropathy
• C. Rapidly progressive glomerulonephritis
• D. Minimal change disease

Answer: (C)

Goodpasture syndrome is characterized by the presence of anti-glomerular basement membrane (anti-GBM) antibodies that lead to specific damage within the kidneys. The type of glomerular damage seen in Goodpasture syndrome is classified as rapidly progressive glomerulonephritis (RPGN). This is due to the rapid and severe inflammation, often resulting in crescent formation in the glomeruli. In RPGN, the damage is acute and severe, leading to a rapid decline in renal function. The infiltration of inflammatory cells and the subsequent crescentic appearance seen in kidney biopsies is a hallmark of this condition. The destruction of the glomerular capillary network occurs so swiftly that it classifies this syndrome as "rapidly progressive." This condition can also affect the lungs, causing pulmonary hemorrhage, which is another critical aspect of Goodpasture syndrome. The presence of both renal and pulmonary symptoms underscores the severity and rapid progression associated with this autoimmune disorder, reinforcing its classification within RPGN.
