ABSTRACT: This article presents a comparison of acute glomerular nephritis (AGN) with rapidly progressive glomerular nephritis (RPGN) in patients aged 60 or older. In 7 elderly patients with AGN, the renal disease was preceded by skin infection (4 cases), sore throat (2 cases), or pneumonia (1 case). The 7 patients with RPGN had no history of prior infection. Both AGN and RPGN were manifested clinically as acute renal failure, but the RPGN patients had significantly higher serum creatinine levels and lower hematocrit readings. Hypocomplementemia was a feature only of AGN. The biopsy specimens from patients with RPGN showed crescents in 50–100 percent of the glomeruli, whereas specimens from patients with AGN showed no significant extracapillary proliferation. Six AGN patients recovered and 1 died. Despite dialysis, 4 RPGN patients died and the remaining 3 require maintenance dialysis. It is concluded that AGN in the elderly is more common than previously believed, frequently follows skin infections, and has a reasonably good prognosis. In contrast, RPGN, also not rare in the elderly, has a much worse prognosis.
