Clinicopathological study of poststreptococcal glomerulonephritis in the elderly

, : Clinicopathological study of poststreptococcal glomerulonephritis in the elderly. Clinical Nephrology 41(5): 265-270

In order to characterize the clinical features in elderly patients with poststreptococcal glomerulonephritis (PSGN), 31 patients, who were both histologically and immunologically proven to be PSGN, were divided up into 3 groups according to age; elderly patients being 55 years or older (n = 7), middle-aged patients being 40 to 54 years old (n = 7) and younger patients being 20 to 39 years old (n = 17). Renal functional impairment as indicated by serum creatinine levels of over 2.0 mg/dl, developed in 4 of the elderly patients and later completely improved at the end of the follow-up period (178.9 +/- 150.7 days). On the other hand, none of the middle-aged and younger patients revealed any renal function impairment. Hypertension was observed more frequently in elderly patients than in younger patients, and was 86% and 6% at the time of admission, respectively. In addition, 43% of elderly patients remained hypertensive at the time of discharge. There was no difference in total protein, ASO, CH50, the degree of proteinuria or proliferative and exudative features in renal histology among the three groups. None of the elderly patients with PSGN died or developed persistent renal failure. In conclusion, elderly patients with PSGN had a high incidence of renal functional impairment and hypertension compared to the younger patients on admission, however, their short-term prognosis seems to be favorable.
