Abstract

Background Aging is accompanied by low-grade inflammation. Tumor necrosis factor (TNF) alpha initiates the cytokine cascade, and high levels are associated with dementia and atherosclerosis in persons aged 100 years. We hypothesized that TNF-alpha was also a prognostic marker for all-cause mortality in these persons.Methods We enrolled 126 subjects at or around the time of their 100th birthday. Plasma levels of TNF-alpha, interleukin (IL)-6, IL-8, and C-reactive protein were measured at baseline, and we determined the associations between the markers of inflammation and mortality during the subsequent 5 years.Results Only 9 subjects were alive after 5 years. Elevated levels of TNF-alpha were associated with mortality in both men and women (hazard ratio = 1.34 per SD of 2.81 pg/mL; 95% confidence interval: 1.12 to 1.60, P = 0.001). Levels of IL-6 and IL-8 did not affect survival; levels of C-reactive protein were not associated with mortality when levels of TNF-alpha were included in the analysis. Dementia and cardiovascular diseases represented the major causes of comorbid conditions at baseline. TNF-alpha was still associated with mortality in multivariate models that included these parameters as confounders.Conclusion TNF-alpha was an independent prognostic marker for mortality in persons aged 100 years, suggesting that it has specific biological effects and is a marker of frailty in the very elderly.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
