Abstract

Frailty is a conglomerated elderly disorder that includes multiple abnormalities, like anemia, an increased titer of catabolic hormones, and compromised physiology of most of the body systems. Many studies have established the biomarkers that correlate with physical function and immune aging; however, people can age differently, so chronological age is not a sufficient marker of susceptibility to disabilities, morbidities, and mortality. The pathophysiology of frailty is not clearly understood, but a critical role of enhanced inflammation in the body is hypothesized. Many factors contribute to the development of frailty syndrome, such as pro-inflammatory cytokines, inflammatory markers, inflammatory cytokines, and secosteroids, like vitamin D. This review aims to highlight the role of inflammatory and cytokine biomarkers and vitamin D in the pathogenesis of Frailty Syndrome.

Keywords: Frailty Syndrome, inflammatory biomarkers, cytokine biomarkers, cytokines, adipocytokines, regulatory T-cells (Tregs), T-cell markers, vitamin D.
