The aim of this cross-sectional study was to investigate the relationship between soluble form of receptor for advanced glycation end products (sRAGE), obesity, and metabolic syndrome (MetS) in adolescents. A total of 522 male and 561 female adolescents were enrolled into the final analyses. Anthropometric parameters, blood pressure, blood biochemistry, fasting insulin, and plasma sRAGE levels were measured. In males, sRAGE was significantly and inversely correlated with waist circumference (WC), body mass index (BMI), systolic blood pressure, triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and homeostasis model assessment-insulin resistance (HOMA-IR). Only WC and BMI were significantly and inversely correlated with sRAGE in females. Using linear regression analysis adjusting for age and gender, significant association was found between sRAGE and WC, BMI, TG, LDL-C, and HOMA-IR in adolescents of either gender (P<0.05). This association was abolished when further adjusting BMI. In addition, sRAGE was significantly and inversely correlated with the increasing number of components of MetS in males (Pfor trend = 0.006) but not in females (Pfor trend = 0.422). In conclusion, plasma sRAGE is associated with obesity and MetS among adolescents. BMI may be the most important determinant of sRAGE levels in adolescents.

Background: Consumption of dietary advanced glycation end products is linked to metabolic syndrome. The objective was to describe the association between dietary advanced glycation end products intake and metabolic syndrome in young Mexican adults. Methods: The present was a cross-sectional study in 126 Mexican adults 18–35 years old evaluating metabolic syndrome through the harmonized criteria. Macronutrients and dietary advanced glycation end products intake were estimated through three 24-hour dietary recalls and food composition tables. Association between metabolic syndrome and high advanced glycation end products intake (≥10,000 kU/day) was evaluated through three logistic regression models adjusted by sex, age, family history of cardiometabolic diseases and energy intake. Results: Subjects with a higher advanced glycation end products intake were more likely to have impaired fasting glucose (OR: 4.91, 95% CI 1.29–18.60, p < 0.05) and metabolic syndrome (OR: 2.67, 95% CI 0.96–7.44, p = 0.059) than those participants with low consumption of these products after adjustment of sex, age, family history of cardiovascular disease and energy intake. Conclusions: High intake of dietary advanced glycation end products was significantly associated with impaired fasting glucose and marginally with metabolic syndrome in young Mexican adults regardless of sex, age, family history of cardiovascular disease and energy intake.

Aortic Stiffening

Aging is associated with stiffening of the large elastic arteries and consequent increases in systolic blood pressure (SBP), which together increase cardiovascular disease risk; however, the upstream mechanisms are incompletely understood. Using complementary translational approaches in mice and humans, we investigated the role of the gut microbiome-derived metabolite trimethylamine N-oxide (TMAO) in age-related aortic stiffening and increased SBP. Aortic stiffness was measured using carotid-femoral or aortic pulse wave velocity (PWV) in humans and mice, respectively. Study 1: Plasma TMAO concentrations were elevated ( P <0.001) in healthy middle-aged to older (6.3±5.8 µmol/L) versus young (1.8±1.4 µmol/L) humans and positively related to carotid-femoral PWV ( r 2 =0.15, P <0.0001) and SBP ( r 2 =0.09, P <0.001), independent of traditional cardiovascular risk factors. Study 2: Dietary supplementation with TMAO increased aPWV in young mice and exacerbated the already elevated aPWV of old mice, accompanied by increases in SBP of ≈10 mm Hg in both groups. TMAO-supplemented versus control-fed mice also had higher intrinsic mechanical stiffness of the aorta (stress-strain testing) associated with higher aortic abundance of advanced glycation end-products, which form crosslinks between structural proteins to promote aortic stiffening. Study 3: Ex vivo incubation of aortic rings with TMAO increased intrinsic stiffness, which was attenuated by the advanced glycation end-products crosslink breaker alagebrium and prevented by inhibition of superoxide signaling. TMAO induces aortic stiffening and increases SBP via formation of advanced glycation end-products and superoxide-stimulated oxidative stress, which together increase intrinsic wall stiffness. Increases in circulating TMAO with aging represent a novel therapeutic target for reducing risk of aortic stiffening-related clinical disorders.

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.

The synergistic effect of the co-morbidities that comprise metabolic syndrome (MetS) is increasingly being recognised as an important contributor in the pathology of a broad spectrum of seemingly disparate conditions. However, in terms of male reproductive function, beyond erectile dysfunction, little is known about the influence of this cohort (collectively or separately) on spermatogenesis and sperm quality. The aims of this study were to assess the reproductive tract of a MetS animal model for detrimental changes, to determine whether a group of compounds (advanced glycation end products and their receptor) known to cause cell dysfunction and DNA damage was present and assess whether hypogonadotropic hypogonadism was the main contributing factor for the changes seen. Animals fed a high-fat diet were found to have significantly increased cholesterol, triglycerides, blood glucose, mean arterial pressure and visceral fat levels. Although serum testosterone was decreased, no changes were seen in either testicular or epididymal histology. Immunolocalisation ofNϵ-carboxymethyl-lysine and the receptor for advanced glycation end products was found in the testes, epididymides and sperm of the two treated groups of animals; however, ELISA did not show any difference in protein levels. Similarly, assessment of sperm nuclear DNA (nDNA) fragmentation by acridine orange test did not find significant differences in nDNA integrity. We conclude that the minimal effect on spermatogenesis and sperm quality seen in our model is probably due to the moderate increase of blood glucose rather than the hypogonadism.

Combined Administration

This study was designed to investigate the effects of combined administration of lipoic acid and pyridoxine on albuminuria, oxidative stress, blood pressure, serum advanced glycation end-products, nitric oxide (NO), and endothelin-1 in patients with diabetic nephropathy. Thirty-four patients were randomly assigned to either a supplement group or a placebo group. The patients in the supplement group received 800 mg lipoic acid and 80 mg pyridoxine daily for 12 weeks, whereas the placebo group received corresponding placebos. Urinary albumin, serum malondialdehyde (MDA), and systolic blood pressure decreased significantly in the supplement group compared to the placebo group (p < 0.05). Serum NO increased in the supplement group compared to the placebo group (p < 0.05). Serum pentosidine and carboxymethyl lysine decreased significantly in the supplement group at the end of week 12 compared to baseline (p < 0.05). No statistically significant differences were observed between the two groups in mean changes of serum endothelin-1, glucose, and diastolic blood pressure. The present study indicates that combined administration of lipoic acid and pyridoxine improves albuminuria in patients with diabetic nephropathy by reducing oxidative stress, advanced glycation end-products, and systolic blood pressure. The reduction in microalbuminuria may be of benefit in retarding the progression of diabetic nephropathy.
