Skin autofluorescence: a pronounced marker of mortality in hemodialysis patients.

Background: Accelerated formation and tissue accumulation of advanced glycation endproducts (AGEs), reflecting cumulative glycemic and oxidative stress, occur in age-related and chronic diseases like diabetes mellitus (DM) and renal failure, and contribute to vascular damage. Skin autofluorescence (AF), a noninvasive measurement method, reflects tissue accumulation of AGEs. The aim of our study was to determine the predictive value of skin AF on overall and cardiovascular mortality in hemodialysis patients.
