Role of intrarenal vascular sclerosis in progression of poststreptococcal glomerulonephritis.
A comparison has been made of the percentage of sclerotic glomeruli found in normal subjects and in 31 patients 6 months to 15 years after an episode of acute poststreptococcal glomerulonephritis (PSGN). The findings establish that a greater than expected incidence of glomerular sclerosis occurs in the course of PSGN. The pattern of glomerular sclerosis frequently was that of contracted collapsed tufts, one known to result from ischemia. In the majority of specimens with significant glomerular sclerosis, there was co-existent vascular sclerosis (arterioles and/or prearterioles), and the incidence of both glomerular and vascular sclerosis increased with time from onset of PSGN. Intrarenal vascular sclerosis may thus be of major importance in the genesis and progression of glomerular sclerosis in PSGN.
