Abstract
- Background and Aims: Modern diets are high in advanced glycation end-products (dAGEs), derived from processing methods, exerting a pivotal role in promoting atherosclerotic risk. In this cross-sectional study we investigate the relationship between dAGE intake, arterial stiffness, inflammatory profile and macronutrient composition, in subjects with type 2 diabetes without overt cardiovascular disease.<br />Methods and Results: Arterial stiffness, carboxy-methyl-lysine, endogenous secretory receptor for AGEs (esRAGE), high sensitivity C reactive protein (hs-CRP), S100A12 and macronutrient intake were evaluated in 85 subjects with type 2 diabetes. The subjects were stratified into two groups according to dAGE consumption: high and low dAGE intake (≥ or <15.000 kU/day, respectively). Subjects with high dAGE intake (n = 45) showed a higher augmentation, augmentation index and pulse wave velocity (PWV) compared with those subjects with low dAGE intake (18 ± 5.4 vs 12.2 ± 6.3 mmHg, P < 0.05; 38.3 ± 5.4 vs 29.3 ± 10%; 9.2 ± 1.4 m/sec vs 7.9 ± 1.7, P < 0.05, respectively). hs-CRP were higher in subjects with high dAGE intake [0.42 (0.18-0.54) vs 0.21 (0.14-0.52) mg/dL, P < 0.05] whereas esRAGE plasma levels were lower [0.16 (0.23-0.81) vs 0.2 (0.14-0.54) ng/dL, P < 0.05]. Simple regression analysis showed a correlation between dAGEs and fat intake. Multivariate analysis showed an independent association between augmentation, systolic blood pressure (BP) and dAGE consumption; BMI and esRAGE were the major determinants of PWV.<br />Conclusions: Our data suggests that a chronic high dAGE diet could lead to a vascular dysfunction and inflammatory activation, contributing to the development of vascular complications in subjects with type 2 diabetes. Testing this hypothesis may represent a direction of future research.<br /> (Copyright © 2017 The Italian Society of Diabetology, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition, and the Department of Clinical Medicine and Surgery, Federico II University.
