What is Skin Advanced Glycation End-products as Indicators of the Metabolic Profile in Diabetes Mellitus: Correlations with Glycemic Control, Liver Phenotypes and Metabolic Biomarkers about?

## Abstract ## Introduction The production of advanced glycation end-products (AGEs) is a key pathomechanism related to the complications of diabetes mellitus. The measurement of HbA1c as one of the AGEs is widely used in the clinic, but also other proteins undergo glycation in the course of diabetes. Here, we measure skin AGEs (SAGEs) in patients with diabetes type 1 (DM1) and type 2 (DM2) and correlate them with metabolic markers as well as non-invasively measured liver fibrosis and steatosis. ## Patients and methods In this cross-sectional study, a total of 64 patients with either DM1 or DM2 and 28 healthy controls were recruited. SAGEs were measured using autofluorescence (AGE Reader). Liver fibrosis and steatosis were quantified using transient elastography, which determines liver stiffness measurement (LSM) and controlled attenuation parameter (CAP). FGF19, FGF21 and GDF-15 were measured in blood samples using ELISA. ## Results SAGEs were elevated in both groups of patients with diabetes as compared to healthy controls (both __p__ < 0.001) and were higher in patients with DM2 in comparison to DM1 (__p__ = 0.006). SAGEs correlated positively with HbA1c (__r__ = 0.404, __p__ <
