Abstract

OBJECTIVES: To investigate whether interleukin‐6 (IL‐6), C‐reactive protein (CRP) and tumor necrosis factor‐alpha (TNF‐α) protein levels predict all‐cause mortality in older persons living in the community. DESIGN: Prospective cohort study. SETTING: Data were from the Aging and Longevity Study in the Sirente Geographic Area, a prospective cohort study. PARTICIPANTS: Individuals aged 80 and older living in an Italian mountain community (N=362). MEASUREMENTS: Participants were classified according to the median value of the three inflammation markers (IL‐6, 2.08 pg/mL; TNF‐α, 1.43 pg/mL; CRP, 3.08 mg/L). A composite summary score of inflammation was also created. The main outcome was risk of death after 4 years of follow‐up. RESULTS: One hundred fifty deaths occurred during 4 years of follow‐up. In the unadjusted model, high levels of each of the three markers were associated with greater mortality. After adjusting for potential confounders, high levels of IL‐6 (hazard ratio (HR)=2.18, 95% confidence interval (CI)=1.29–3.69) and CRP (HR=2.58, 95% CI=1.52–4.40) were associated with a significantly greater risk of death, whereas the association between TNF‐α protein levels and mortality was no longer significant (HR=1.26, 95% CI=0.74–2.15). The composite summary score of inflammation was strongly associated with mortality, with the highest risk estimated for individuals with all three inflammatory markers above the median. CONCLUSION: Low levels of inflammatory markers are associated with better survival in older adults, independent of age and other clinical and functional variables.

  • The most frail older individuals have the highest circulating levels of CRP, IL-6, and IL-8.

    “those older individuals who are most frail have highest levels of circulating CRP, IL-6 and IL-8 (23).”

  • Inflammation strongly predicts frailty.

    “Inflammation is a strong predictor for frailty, and those older individuals who are most frail have highest levels of circulating CRP, IL-6 and IL-8 (23).”

  • Higher inflammatory activity, measured by plasma or serum interleukin (IL)-6, tumour necrosis factor-α (TNF-α) and C-reactive protein (CRP), has also been associated with shorter survival.

    “In addition, higher inflammatory activity, measured by plasma or serum interleukin (IL)-6, tumour necrosis factor-α (TNF-α) and C-reactive protein (CRP), has also been associated with shorter survival (Baune et al. 2011; Bruunsgaard et al. 2003; Giovannini et al. 2011).”

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.
