Abstract Objectives Excessive consumption of advanced glycation end products (AGEs) with western-style diet in vogue is increasingly seen as a potential cause of aging and metabolic diseases. Several berries contain appreciable quantities of bioactive phytonutrients, including phenolic compounds, which are potentially good candidates as AGE inhibitors. This parallel double-blind intervention study investigated whether the Vaccinium Myrtillus extract supplement is able to reduce the AGEs levels in humans. (clinicaltrials.gov NCT03316612) Methods Seventy-four healthy subjects were randomly assigned to an intervention group (4 tablets per day, containing 600 mg Vaccinium Myrtillus extract, n = 39) versus placebo group (tablets with the same appearance but without the berry extract, n = 35). We evaluated dietary intake, sleep, exercise, mental state, and anthropometric characteristics over the 3 months of intervention. Plasma soluble receptor for AGE (sRAGE) levels were determined by ELISA (R&D). Plasma protein-bound AGEs, including Nε-(carboxymethyl)lysine (CML) and Nε-(carboxyethyl)lysine (CEL), were determined by ultra-high performance liquid chromatography-tandem mass spectrometry. Results Dietary intake, sleep, exercise, mental state, anthropometric characteristics, and plasma sRAGE levels were not changed during the intervention in two groups. CML levels [1137.5 (918.5–1493.0) vs. 840.9 (757.4–953.8) μg/L, P < 0.001] decreased significantly in the intervention group compared with the placebo group. However, we did not observe a significant change of CEL levels [201.9 (168.5–236.3) vs.176.8 (147.1–212.6) μg/L, P = 0.067] in the intervention group. Conclusions Our results suggest that plasma protein-bound AGEs can be reduced partly by Vaccinium Myrtillus extract supplement. As widely available, safe and nutritious foods, berries with rich phenolic metabolites (particularly anthocyanins) represent a promising dietary intervention worthy of further investigation.

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.

Advanced glycation end-products (AGEs) may promote oxidative stress and inflammation and have been linked to multiple chronic diseases, including cancer. However, the association of AGEs with mortality after colorectal cancer (CRC) diagnosis has not been previously investigated. Multivariable Cox proportional hazards models were used to calculate hazard ratios and corresponding 95% confidence intervals for associations between dietary intake of AGEs with CRC-specific and all-cause mortality among 5801 participant cases diagnosed with CRC in the European Prospective Investigation into Cancer and Nutrition study between 1993 and 2013. Dietary intakes of AGEs were estimated using country-specific dietary questionnaires, linked to an AGE database, that accounted for food preparation and processing. During a median of 58 months of follow-up, 2421 cases died (1841 from CRC). Individually or combined, dietary intakes of AGEs were not associated with all-cause and CRC-specific mortality among cases. However, there was a suggestion for a positive association between AGEs and all-cause or CRC-specific mortality among CRC cases without type II diabetes (all-cause, Pinteraction = 0.05) and CRC cases with the longest follow-up between recruitment and cancer diagnosis (CRC-specific, Pinteraction = 0.003; all-cause, Pinteraction = 0.01). Our study suggests that pre-diagnostic dietary intakes of AGEs were not associated with CRC-specific or all-cause mortality among CRC patients. Further investigations using biomarkers of AGEs and stratifying by sex, diabetes status, and timing of exposure to AGEs are warranted.
