Effect of Aspirin on Disability-free Survival in the Healthy Elderly.

ABSTRACT: BACKGROUND:Information on the use of aspirin to increase healthy independent life span in older persons is limited. Whether 5 years of daily low-dose aspirin therapy would extend disability-free life in healthy seniors is unclear. METHODS:From 2010 through 2014, we enrolled community-dwelling persons in Australia and the United States who were 70 years of age or older (or ?65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or physical disability. Participants were randomly assigned to receive 100 mg per day of enteric-coated aspirin or placebo orally. The primary end point was a composite of death, dementia, or persistent physical disability. Secondary end points reported in this article included the individual components of the primary end point and major hemorrhage. RESULTS:A total of 19,114 persons with a median age of 74 years were enrolled, of whom 9525 were randomly assigned to receive aspirin and 9589 to receive placebo. A total of 56.4% of the participants were women, 8.7% were nonwhite, and 11.0% reported previous regular aspirin use. The trial was terminated at a median of 4.7 years of follow-up after a determination was made that there would be no benefit with continued aspirin use with regard to the primary end point. The rate of the composite of death, dementia, or persistent physical disability was 21.5 events per 1000 person-years in the aspirin group and 21.2 per 1000 person-years in the placebo group (hazard ratio, 1.01; 95% confidence interval [CI], 0.92 to 1.11; P=0.79). The rate of adherence to the assigned intervention was 62.1% in the aspirin group and 64.1% in the placebo group in the final year of trial participation. Differences between the aspirin group and the placebo group were not substantial with regard to the secondary individual end points of death from any cause (12.7 events per 1000 person-years in the aspirin group and 11.1 events per 1000 person-years in the placebo group), dementia, or persistent physical disability. The rate of major hemorrhage was higher in the aspirin group than in the placebo group (3.8% vs. 2.8%; hazard ratio, 1.38; 95% CI, 1.18 to 1.62; P<0.001). CONCLUSIONS:Aspirin use in healthy elderly persons did not prolong disability-free survival over a period of 5 years but led to a higher rate of major hemorrhage than placebo.

Project description:BackgroundIn the primary analysis of the Aspirin in Reducing Events in the Elderly (ASPREE) trial, now published in the Journal, we report that the daily use of aspirin did not provide a benefit with regard to the primary end point of disability-free survival among older adults. A numerically higher rate of the secondary end point of death from any cause was observed with aspirin than with placebo.MethodsFrom 2010 through 2014, we enrolled community-dwelling persons in Australia and the United States who were 70 years of age or older (or ≥65 years of age among blacks and Hispanics in the United States) and did not have cardiovascular disease, dementia, or disability. Participants were randomly assigned to receive 100 mg of enteric-coated aspirin or placebo. Deaths were classified according to the underlying cause by adjudicators who were unaware of trial-group assignments. Hazard ratios were calculated to compare mortality between the aspirin group and the placebo group, and post hoc exploratory analyses of specific causes of death were performed.ResultsOf the 19,114 persons who were enrolled, 9525 were assigned to receive aspirin and 9589 to receive placebo. A total of 1052 deaths occurred during a median of 4.7 years of follow-up. The risk of death from any cause was 12.7 events per 1000 person-years in the aspirin group and 11.1 events per 1000 person-years in the placebo group (hazard ratio, 1.14; 95% confidence interval [CI], 1.01 to 1.29). Cancer was the major contributor to the higher mortality in the aspirin group, accounting for 1.6 excess deaths per 1000 person-years. Cancer-related death occurred in 3.1% of the participants in the aspirin group and in 2.3% of those in the placebo group (hazard ratio, 1.31; 95% CI, 1.10 to 1.56).ConclusionsHigher all-cause mortality was observed among apparently healthy older adults who received daily aspirin than among those who received placebo and was attributed primarily to cancer-related death. In the context of previous studies, this result was unexpected and should be interpreted with caution.

Project description:OBJECTIVES:To examine the prospective association between kidney function and three outcomes: survival to age 85 with functional independence, survival to age 85 with disability, and death before age 85. DESIGN:Prospective study. SETTING:Women's Health Initiative, conducted at 40 U.S. clinical centers. PARTICIPANTS:Postmenopausal women enrolled between 1993 and 1998 with baseline biomarker assessments who had the potential to reach age 85 before September 2013 (N = 7,178). MEASUREMENTS:Kidney function was measured according to estimated glomerular filtration rate (eGFR) calculated from serum creatinine collected at baseline. Outcomes were survival to age 85 with functional independence, survival with disability, or death before age 85. Disability was defined as mobility or activity of daily living limitations measured by questionnaire. RESULTS:eGFR was greater than 90 mL/min per 1.73 m2 in 22.7% of women, 60 to 89 mL/min per 1.73 m2 in 66.5%, 45 to 59 mL/min per 1.73 m2 in 8.7%, and less than 45 mL/min per 1.73 m2 in 2.0%. Median follow-up was 15 years. Of 4,953 survivors, 3,155 reported no physical disability at age 85. Two thousand two hundred twenty-five participants died before age 85. Women with an eGFR of 90 mL/min per 1.73 m2 or greater had 2.71 times greater odds of survival to age 85 with functional independence than of dying before 85 (95% confidence interval (CI) = 1.62-4.51) than those with an eGFR less than 45 mL/min per 1.73 m2 , women with an eGFR of 60 to 89 mL/min per 1.73 m2 had 3.04 times (95% CI = 1.85-5.00) greater odds, and women with an eGFR of 45 to 59 mL/min per 1.73 m2 had 2.22 times (95% CI = 1.31-3.76) greater odds. Similar, but slightly weaker odds were seen for survival to age 85 with disability. Better kidney function was not significantly associated with greater likelihood of survival to age 85 with independent function than of surviving with disability. CONCLUSION:Better kidney function was associated with greater likelihood of survival to age 85 with and without disability.
