Hemodialysis in the eighth and ninth decades of life.
In a review of 45 patients who started receiving hemodialysis (HD) after the age of 70 years (mean, 75 years), compared with a control of 70 HD patients (mean age, 42 years), the two-year survival for elderly patients was 42% and 58% for controls. In the elderly group, age did not correlate with survival. Nine elderly patients were over 80 years old and had a two-year survival of 41%. The elderly patients had a significantly lower mean predialysis blood pressure (BP) (142/73 +/- 3/1 mm Hg) than the controls (158/88 +/- 2/1 mm Hg) (P less than .001). Only 13% of the elderly patients received antihypertensive medication, compared with 41% of controls (P less than .01). The BP showed a significant negative correlation with age in both elderly ( r - .41, P less than .01) and control (r = .35, P less than .001) patients. Glomerulonephritis was less common in the elderly (9%) than control (31%) groups, and pyelonephritis was more common (29% vs 16%).
