What is the Origin of Systemic Inflammation Levels?

This concept originates from immunology and pathology, with the clinical term evolving to describe the pathological state of chronic, sterile inflammation. The realization that persistent, low-level immune activation significantly contributes to the aging process led to the coining of "inflammaging." The clinical utility of measuring these levels grew as high-sensitivity assays for markers like hs-CRP became widely available for risk stratification.

What is the Mechanism of Systemic Inflammation Levels?

Chronic systemic inflammation is primarily driven by accumulated cellular damage, senescent cell accumulation, and persistent metabolic stress, such as chronic hyperglycemia or visceral adiposity. These stimuli activate immune cells and trigger the release of pro-inflammatory cytokines into the bloodstream. These circulating mediators then disrupt normal endothelial function, impair insulin signaling, and contribute to tissue damage across distant organs, perpetuating a vicious cycle of physiological decline.

Systemic Inflammation Levels

Meaning

Systemic inflammation levels quantify the concentration of circulating pro-inflammatory biomarkers, such as C-reactive protein (CRP), interleukins, and tumor necrosis factor-alpha (TNF-α), that reflect a low-grade, chronic inflammatory state affecting the entire organism. This state, often termed “inflammaging,” is distinct from acute immune responses and is a key driver of age-related pathology, including cardiovascular disease, insulin resistance, and neurodegeneration. Clinically, measuring these levels is essential for assessing biological age and the overall burden of chronic disease risk.
