Skin autofluorescence of Advanced Glycation End-products and mortality in older adults: The roles of chronic kidney disease and diabetes. Nutr Metab Cardiovasc Dis 2022; 32:2526-2533. [PMID: 36064683 DOI: 10.1016/j.numecd.2022.08.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 06/27/2022] [Accepted: 08/05/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND AND AIM Advanced glycation end products are involved in age-related multisystem decline. They accumulate in body tissues with age, diabetes and chronic kidney disease (CKD), and can be measured non-invasively by the skin autofluorescence (SAF). We studied the relation between SAF and later mortality in old adults. METHODS AND RESULTS The SAF was measured using an AGE-Reader in 451 individuals from the general population aged over 75 years, and all-cause mortality was assessed during an average follow-up of 6.4 years. The association between SAF and mortality was analyzed using a multivariate Cox survival model, adjusted for age and gender. Analyses were further adjusted for diabetes and stratified on the presence of CKD due to its interaction with SAF for the risk of mortality. Participants were 82 years old on average (SD 4.1). Their mean SAF was 2.8 AU (SD 0.6). One hundred and forty-four individuals (31.9%) died during the follow-up. Adjusted for age and gender, SAF was associated with an increased risk of all-cause mortality (HR 1.44, 95%CI: 1.14-1.82 for a one-AU increase of SAF). The association was no longer significant after adjustment for diabetes. However, after stratification for the presence of CKD, higher SAF was associated with an increased risk of all-cause mortality in the participants with CKD at baseline (HR 1.68, 95%CI: 1.11-2.55), whereas there was no association among participants without CKD (HR 0.95, 95%CI: 0.63-1.44). CONCLUSION Skin autofluorescence is associated with increased all-cause mortality in older adults already suffering from CKD.

BMC Complement Med Ther 2020; 20:130. [PMID: 32345291 PMCID: PMC7189569 DOI: 10.1186/s12906-020-02925-4] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2019] [Accepted: 04/14/2020] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Paeoniae Radix Alba, the root of the plant Paeonia lactiflora Pall, is a common blood-enriching drug in traditional Chinese medicine. Its effectiveness in the clinical treatment of anaemia is remarkable, but its potential pharmacologic mechanism has not been clarified. METHODS In this study, the potential pharmacologic mechanism of Paeoniae Radix Alba in the treatment of iron-deficiency anaemia was preliminarily elucidated through systematic and comprehensive network pharmacology. RESULTS Specifically, we obtained 15 candidate active ingredients from among 146 chemical components in Paeoniae Radix Alba. The ingredients were predicted to target 77 genes associated with iron-deficiency anaemia. In-depth analyses of these targets revealed that they were mostly associated with energy metabolism, cell proliferation, and stress responses, suggesting that Paeoniae Radix Alba helps alleviate iron-deficiency anaemia by affecting these processes. In addition, we conducted a core target analysis and a cluster analysis of protein-protein interaction (PPI) networks. The results showed that four pathways, the p53 signalling pathway, the IL-17 signalling pathway, the TNF signalling pathway and the AGE-RAGE signalling pathway in diabetic complications, may be major pathways associated with the ameliorative effects of Paeoniae Radix Alba on iron-deficiency anaemia. Moreover, molecular docking verified the credibility of the network for molecular target prediction. CONCLUSIONS Overall, this study predicted the functional ingredients in Paeoniae Radix Alba and their targets and uncovered the mechanism of action of this drug, providing new insights for advanced research on Paeoniae Radix Alba and other traditional Chinese medicines.

Abstract
Large artery stiffness is a frequent condition that arises with ageing, and is accelerated by the presence of co-morbidities like hypertension, obesity and diabetes. Although epidemiological studies have indicated an association between arterial stiffness, cognitive impairment and dementia, the precise effects of stiff arteries on the brain remains obscure. This is because, in humans, arterial stiffness is often accompanied by other factors such as age, high blood pressure, atherosclerosis and inflammation, which could themselves damage the brain independently of stiffness. Therefore, the question remains: is arterial stiffness a true risk for cognitive decline? Or, is it a confounding factor? In this review, we provide an overview of arterial stiffness and its impact on brain function based on human and animal studies. We summarize the evidence linking arterial stiffness to cognitive dysfunction and dementia, and discuss the role of new animal models to better understand the mechanisms by which arterial stiffness affects the brain. We close with an overview of treatments to correct stiffness and discuss the challenges to translate them to real patient care. This article is part of the Special Issue "Vascular Dementia".

Abstract
Advanced glycation end products (AGEs) are a family of compounds of diverse chemical nature that are the products of nonenzymatic reactions between reducing sugars and proteins, lipids, or nucleic acids. AGEs bind to one or more of their multiple receptors (RAGE) found on a variety of cell types and elicit an array of biologic responses. In this review, we have summarized the data on the nature of AGEs and issues associated with their measurements, their receptors, and changes in their expression under different physiologic and disease states. Last, we have used this information to prescribe lifestyle choices to modulate AGE-RAGE cycle for better health.

Abstract
INTRODUCTION More than 10% of the aged 65 years and over in the western world suffers anemia and in one third of them the cause of the anemia remains obscure. The unexplained anemia of the elderly (UAE) is considered an exclusion diagnosis, without the existence of a clear consensus to its clinical or experimental approach. There is an association between aging and anemia in studies performed in animals and in humans. OBJECTIVES To determine if there is evidence in the literature that supports hematopoietic stem cells (HSC) exhaustion and the advanced glycation end-products (AGE's) as a cause of UAE. METHOD A total of 32 combined texts (28 for HSC exhaustion and 4 for AGEs) were selected after an intensive review. Conclusions were associated with causes and effects of the HSC exhaustion and circulating AGE's over aging and anemia. RESULTS Only three works try to establish an association between UAE and HSC exhaustion, two of them disagreed in their conclusions, with the third one differing in the type of study. There is a relationship between anemia and AGEs increase and accumulation. CONCLUSIONS There is evidence in the literature that links the aging molecular and cellular mechanisms with the HSC exhaustion and the increase of AGE's. Furthermore; there is some evidence that both conditions determine the emergence of anemia associated with age in animals and in humans. There is little evidence in the literature to clarify the relationship between aging and UAE.

Abstract
Reactive derivatives from nonenzymatic glucose-protein condensation reactions, as well as lipids and nucleic acids exposed to reducing sugars, form a heterogeneous group of irreversible adducts called AGEs (advanced glycation end products). The glycation process begins with the conversion of reversible Schiff base adducts to more stable, covalently bound Amadori rearrangement products. Over the course of days to weeks, these Amadori products undergo further rearrangement and condensation reactions to form irreversibly cross-linked macroprotein derivatives known as AGEs. The formation and accumulation of AGEs have been known to progress in a physiological aging process and at an accelerated rate under hyperglycemic and oxidative stress conditions. There is growing evidence that AGEs play a pathologic role in numerous disorders. Indeed, glycation and/or cross-linking modification of circulating or organic matrix proteins by AGEs the senescence of moieties and deteriorate their physiological function and structural integrity in multiple organ systems. Moreover, AGEs elicit oxidative stress and inflammatory reactions through the interaction with the receptor for advanced glycation products in a variety of cells, thereby contributing to the development and progression of various aging- or diabetes-related disorders, such as cardiovascular disease, chronic kidney disease, insulin resistance, and Alzheimer's disease. Recently, diet has been recognized as a major environmental source of AGEs that could cause proinflammatory reactions and organ damage in vivo. Therefore, this review summarizes the pathophysiological role of dietary AGEs in health and disease, especially focusing on cardiometabolic disorders. We also discuss the potential utility in targeting exogenously derived AGEs for therapeutic intervention.

Abstract
AbstractAdvanced glycation end products (AGEs) and the receptor RAGE interaction is involved in nonalcoholic fatty liver disease (NAFLD). Although exogenously administered soluble RAGE (sRAGE) has been shown to block the harmful effects of AGEs in animal models, there is still controversy about the role of sRAGE in humans. We examined here which anthropometric, metabolic and clinical variables were independent correlates of sRAGE levels in NAFLD patients. The study involved 77 biopsy-proven, unmedictaed NAFLD patients (44 male and 33 female) with a mean age of 43.4±13.0 years old. We examined which anthropometric, metabolic and clinical variables, including liver steatosis and fibrosis markers, are independently associated with serum levels of sRAGE. Mean serum levels of sRAGE were 710.7±290.2 pg/mL. Univariate analysis revealed that waist circumference (inversely), hemoglobin (inversely), number of white blood cells (inversely), total-bilirubin (inversely), free fatty acid (inversely), ferritin (inversely), and HbA1c (inversely) were significantly correlated with serum levels of sRAGE. In multiple stepwise regression analysis, waist circumference (p<0.01, inversely) and hemoglobin (p<0.01, inversely) were independently associated with serum levels of sRAGE (R2=0.176). The present study reveals that low serum levels of sRAGE are independently associated with waist circumference and hemoglobin in patients with NAFLD.

Abstract
OBJECTIVE To assess whether selenium and carboxymethyl-lysine (CML), two biomarkers of oxidative stress, are independent predictors of anemia in older community-dwelling adults. METHODS Plasma levels of selenium, CML, folate, vitamin B12, and testosterone and markers of iron status and inflammation were measured at baseline in 1036 adults at least 65 y old in the Invecchiare in Chianti Study, a population-based cohort study of aging in Tuscany, Italy, and examined in relation to prevalent anemia and incident anemia over 6 y of follow-up. RESULTS At enrollment, 11.6% of participants were anemic. Of 472 participants who were non-anemic at enrollment, 72 (15.3%) developed anemia within 6 y of follow-up. At enrollment, plasma CML in the highest quartile (>425 ng/mL) and plasma selenium in the lowest quartile (<66.6 μg/L) predicted incident anemia (hazard ratio 1.67, 95% confidence interval 1.07-2.59, P = 0.02; hazard ratio 1.55, 95% confidence interval 1.01-2.38, P = 0.05, respectively) in a multivariate Cox proportional hazards model that adjusted for age, education, body mass index, cognition, inflammation, red blood cell distribution width, ferritin, vitamin B12, testosterone, and chronic diseases. CONCLUSION Elevated plasma CML and low plasma selenium are long-term independent predictors of anemia in older community-dwelling adults. These findings support the idea that oxidative stress contributes to the development of anemia.

Abstract
BACKGROUND Advanced glycation end products (AGEs) are thought to cause inflammation through interaction with the receptor for AGEs (RAGE), therefore contributing to adverse aging-related processes. The relationship between AGEs, RAGE, and inflammation has not been well characterized. METHODS We examined the relationship of plasma endogenous secretory RAGE (esRAGE); carboxymethyl-lysine (CML), a circulating AGE; and inflammatory mediators in 1,298 adults, 20-97 years, who participated in the InCHIANTI study in Tuscany, Italy. Blood levels of esRAGE, CML, interleukin-1 receptor antagonist (IL-1RA), IL-1β, tumor necrosis factor-α (TNF-α), IL-6, IL-6 receptor (IL-6R), IL-18, C-reactive protein (CRP), transforming growth factor-β (TGF-β), and fibrinogen were measured. RESULTS Log plasma esRAGE was associated with log IL-1RA (β = -0.069, SE = 0.036, p = .05) and log IL-6 (β = 0.077, SE = 0.035, p = .03), respectively, in separate multivariable linear regression models, adjusting for potential confounders. Log plasma esRAGE was also negatively associated with log TGF-β but did not reach statistical significance (β = -0.091, SE = 0.053, p = .09). Log plasma esRAGE was not significantly associated with log IL-1β, log TNF-α, IL-6R, log IL-18, or CRP. Log plasma CML was not associated with any of the inflammatory mediators except for IL-6R (β = -14.10, SE = 5.94, p = .02) and fibrinogen (β = 13.95, SE = 7.21, p = .05) in separate multivariable models, adjusting for potential confounders. CONCLUSIONS Plasma esRAGE is correlated with higher IL-6 and lower IL-1RA. These findings suggest that plasma esRAGE plays a role in modulating inflammation, although the exact mechanisms remain to be elucidated.

Abstract
BACKGROUND Aging is a complex multifactorial process characterized by accumulation of deleterious changes in cells and tissues, progressive deterioration of structural integrity and physiological function across multiple organ systems, and increased risk of death. METHODS We conducted a review of the scientific literature on the relationship of advanced glycation end products (AGEs) with aging. AGEs are a heterogeneous group of bioactive molecules that are formed by the nonenzymatic glycation of proteins, lipids, and nucleic acids. RESULTS Humans are exposed to AGEs produced in the body, especially in individuals with abnormal glucose metabolism, and AGEs ingested in foods. AGEs cause widespread damage to tissues through upregulation of inflammation and cross-linking of collagen and other proteins. AGEs have been shown to adversely affect virtually all cells, tissues, and organ systems. Recent epidemiological studies demonstrate that elevated circulating AGEs are associated with increased risk of developing many chronic diseases that disproportionally affect older individuals. CONCLUSIONS Based on these data, we propose that accumulation of AGEs accelerate the multisystem functional decline that occurs with aging, and therefore contribute to the aging phenotype. Exposure to AGEs can be reduced by restriction of dietary intake of AGEs and drug treatment with AGE inhibitors and AGE breakers. Modification of intake and circulating levels of AGEs may be a possible strategy to promote health in old age, especially because most Western foods are processed at high temperature and are rich in AGEs.
