title: A clinical and pathological study on the characteristics and factors influencing the prognosis of crescentic glomerulonephritis using a cluster analysis.
abstract: Crescentic glomerulonephritis (CrGN) is expressed by a rapidly progressive lesion. However, there is no unanimous view on the factors that affect the prognosis. We carried out a follow-up study of 109 CrGN patients consisting of 54 males (age 55.3 +/- 15.7) and 55 females (age 54.0 +/- 16.3) by a cluster analysis using pathomorphological parameters at the time of biopsy, and thus found two categories which were significantly different regarding the speed of progress (P = 0.0249). The component factors of rapidly progressive CrGN included a combination of several factors such as: (i) a high frequency of crescents; (ii) frequent sclerosis and hyalinosis in the glomeruli with crescents; (iii) extensive tubulo-interstitial damage (cellular, fibrocellular and fibrous) in the renal cortex; (iv) hyperproteinuria; (v) high mean blood pressure; and (vi) anemia. Thus, the prognosis of CrGN is regulated by no single factor but instead by a complex combination of mutually associated factors.
