What is the Origin of Chronic Inflammatory Burden?

The concept emerged from the recognition that many non-infectious chronic diseases share a common pathway of unresolved, sterile inflammation, a phenomenon termed "inflammaging" in gerontology. The term 'burden' is used to quantify the overall physiological cost and destructive potential of this sustained immune activation on the entire organism. Clinical translation involves identifying specific biochemical markers, such as high-sensitivity C-reactive protein, to assess this underlying state.

What is the Mechanism of Chronic Inflammatory Burden?

The mechanism involves the persistent activation of nuclear factor kappa B (NF-κB) pathways and the inflammasome within various cell types, particularly immune cells and adipocytes. This cascade drives the overproduction of inflammatory mediators like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α). This sustained cytokine exposure directly interferes with insulin receptor sensitivity and thyroid hormone conversion, creating a vicious cycle of metabolic and endocrine disruption that accelerates biological aging.

Chronic Inflammatory Burden

Meaning

Chronic Inflammatory Burden refers to the cumulative, low-grade, persistent activation of the innate immune system that does not resolve efficiently, leading to continuous systemic tissue damage and dysfunction. This state, often subclinical, involves the sustained release of pro-inflammatory cytokines and acute-phase proteins that disrupt normal metabolic and hormonal signaling. It is a critical, measurable risk factor underlying many age-related and chronic diseases, placing a significant demand on the body’s homeostatic mechanisms.
