Autofluorescence measurements are based on the detection of AGEs in the skin.  High skin autofluorescence is associated with high risk of cardiovascular complications and mortality in people with type 2 diabetes, as well as renal failure. However, whether this non-invasive measurement can be used as a predictive biomarker in the general population has not been elucidated. In this issue, van Waateringe et al (https://doi.org/10.1007/s00125-018-4769-x) examined whether measurement of skin autofluorescence can predict 4 year risk of incident type 2 diabetes, cardiovascular disease (CVD) and mortality in the general population. They report that a higher skin autofluorescence is associated with a higher risk of developing type 2 diabetes and CVD in people free of these diseases at baseline. In addition, they found that baseline skin autofluorescence was elevated in individuals who had died over the follow-up period, compared with individuals who survived. These findings were independent of other important risk factors, such as blood glucose, HbA1c and classical risk factors, including high blood pressure, high cholesterol and smoking. These findings suggest that measurement of skin autofluorescence is of clinical value for screening for future risk of type 2 diabetes, CVD and mortality and can improve risk estimates for these conditions.
