Abstract
In the field of frailty, there is an underlying hypothesis that chronic low-grade inflammation contributes to bad outcomes in response to a stressor. The host response to an Escherichia coli infection was assessed in 24 month old male rats exhibiting a chronic low-grade inflammation and in non-inflamed control rats. Mortality, weight loss and sarcopenia were the main outcomes measured. The presence of chronic low-grade inflammation did not affect post-infection mortality, body weight loss and tissue mass decreases. Infection-induced modifications of plasma acute phase proteins concentrations were not higher in low-grade inflamed than non-inflamed rats. Absolute synthesis rates of tissue proteins were independent of the initial inflammatory status, except for liver 10 days after infection. Altogether, age-associated chronic low-grade inflammation in male rats did not worsen the body response to bacterial infection. These results suggest that chronic low-grade inflammation is not an aggravating factor of the spiraling process leading to frailty.
