Abstract

Frailty is the main geriatric syndrome, which is closely associated with age-related diseases and aging in general. Being considered the main pathogenetic mechanism of aging, low-grade chronic inflammation potentially contributes to increased degradation of the essential amino acid tryptophan through the kynurenine pathway. Active metabolites of the kynurenine pathway, when accumulated, implement their immunomodulatory, pro-inflammatory and cytotoxic properties, thereby supporting and enhancing the aging process. Over the past decade, data have been collected on the role of an unbalanced kynurenine pathway in the pathogenesis of frailty and age-related diseases. This review summarizes clinical and experimental data on the importance of kynurenine pathway analysis as a valuable tool for risk stratification and prognosis of frailty and age-related diseases.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
