Purpose:

Aging is associated with a variety of changes in the immune system. These changes result in a less effective immune response, which places the elderly at a greater risk for infection and disease. Respiratory infections cause a great number of morbidity and mortality in the elderly population. Vitamin E has been known to improve the immune response of the elderly and has been suggested for use in preventative strategies for this population. The purpose of this study is to examine the effect of one year vitamin supplementation on respiratory infection in the elderly population residing in nursing homes. This study was conducted using a randomized, double blind, placebo controlled clinical trial at 33 long-term care facilities in the greater Boston area. A total of 617 subjects over the age of 65 were enrolled in the study, with 451 completers. The participants were supplemented wit either 200 IU of vitamin E per day or placebo. The primary outcomes consisted of respiratory tract infection, number of sick days, and antibiotic use. The study involved use of questionnaires, standard anthropometrics measurements, non-invasive body composition, blood and urine sample collection, and delayed type test (DTH) using the Mantoux method. This study has been closed since August 2000 and is in the stage of data analysis only.
