The Relationship

Abstract Objectives Advanced Glycation End Products, (AGEs) and their soluble receptor (sRAGE) have been implicated in the development of complications and mortality among individuals with type 2 diabetes (T2D). There is limited information on the relationship between AGEs and sRAGE and risk of cardiovascular diseases (CVD) in minority groups, who have a higher burden of T2D. The relationship between AGEs and sRAGE and CVD risks in adults with T2D and vitamin D insufficiency/deficiency was assessed in a minority population. Methods A cross sectional study of Hispanics and African Americans with T2D (n = 64, 41 women and 23 men, mean age = 54 ± 9) recruited from two clinics in Miami Dade. Systolic (SBP) and diastolic blood pressure (DBP), weight and height measurement and serum lipid profile were completed. ELISA kits were used to assess serum levels of AGEs (Biotang Inc/TSZ Elisa, Waltham, MA, USA) and sRAGE (Biotang Inc/TSZ Elisa, Waltham, MA, USA). Multiple linear regression was used to assess association between AGEs, sRAGE and CVD risks. Results A negative and significant association between AGEs and high-density lipoprotein cholesterol (HDL-C)(B = −0.551, P = 0.029) was found. The relationship between AGEs and HDL-C persisted after adjusting for covariates (P < 0.05). sRAGE was significantly associated with SBP (B = 0.015, P = 0.025) and diastolic blood pressure DBP (B = 0.0271, P = 0.037). Results loss significance when association between sRAGE and DBP and SBP were adjusted for covariates such as age, body mass index (BMI), smoking and alcohol intake. Conclusions Our results suggest that AGEs and sRAGE are related to markers of cardiovascular risk such as HDL-C, SBP and DBP in the study population of African Americans and Hispanics with T2D and vitamin D insufficiency/deficiency. Measures on reducing serum levels of AGEs and improving sRAGE and vitamin D are warranted in these populations for risk reduction of CVD. Funding Sources Partial funding for this research was provided through an NIH/NIDDK sponsored grant.

Objectives. This study investigated the association between polymorphisms in the receptor for advanced glycation end products (RAGE) gene and the susceptibility to diabetic retinopathy (DR) in a Chinese population and identified a correlation between serum-soluble RAGE (sRAGE) levels and DR risk.Materials and Methods. We enrolled 1040 patients with type 2 diabetes mellitus: 372 patients with DR and 668 without retinopathy (NDR). All polymorphisms were genotyped by time-of-flight mass spectrometry. Serum levels of sRAGE were assayed by enzyme-linked immunosorbent assays. The interaction of SNPs was analyzed by multifactor dimensionality reduction (MDR).Results. The frequency of the SS genotype for the G82S polymorphism was 12.4% in the DR group and 6.6% in the NDR group; this difference was significant. G82S was associated with sRAGE levels. Specifically, after adjustments for age, sex, duration, and glucose metabolism, serum sRAGE levels were significantly higher in DR subjects with the S/S genotype than in NDR subjects in general. In the DR group, subjects with the G/S genotype had lower sRAGE levels than subjects with the G/G or S/S genotype (P<0.01). The best multilocus genetic interaction model was assessed using the MDR method; 2184A/G, 1704G/T, G82S, and −429T/C were identified.Conclusions. The findings suggest that the G82S polymorphism in theRAGEgene is associated with DR risk, and G82S was associated with circulating levels of sRAGE. The mechanism by which G82S polymorphism modulates the sRAGE levels remains to be elucidated.

Abstract Background 1,5-anhydroglucitol is a reduction product of 1,5-anhydrofructose. Circulating 1,5-anhydroglucitol is usually excreted by the kidneys and is reabsorbed via sodium-glucose co-transporter 4 in the renal tubules. In patients on hemodialysis, serum levels of 1,5-anhydroglucitol have been reported to be low; however, the underlying mechanism remains unclear. Methods We measured inter-dialysis changes in the levels of serum 1,5-anhydroglucitol and 1,5-anhydrofructose-derived advanced glycation end products (AGEs) in 78 patients on hemodialysis. Serum levels of 1,5-anhydrofructose-derived AGEs were also determined using a polyclonal antibody. Results The serum 1,5-anhydroglucitol level was decreased to as low as 2.0 μg/mL in the regular hemodialysis group; however, we could not verify changes in the serum 1,5-anhydroglucitol level during inter-dialysis days because of undetectable levels in 29 patients. The measured serum level of 1,5-anhydrofructose-derived AGEs was significantly increased in both patient groups. In addition, the 1,5-anhydrofructose-derived AGEs/1,5-anhydroglucitol ratio was higher in patients on hemodialysis than in controls. Conclusions Accelerated glycation of 1,5-anhydrofructose is one possible mechanism by which serum 1,5-anhydroglucitol levels are lowered in patients on HD, and we propose that the 1,5-anhydrofructose-derived AGEs/1,5-anhydroglucitol ratio should be measured in clinical settings in which patients have low serum levels of 1,5-AG.
