FRUCTOSE INDUCED HYPERURICEMIA PDF

Fructose-Induced Hyperuricemia Is Associated With a Decreased Renal Uric Acid Excretion in Humans. Virgile Lecoultre, PHD1,; Léonie Egli, MSC1,; Fanny. Fructose-induced hyperuricemia and hyperuricaciduria is associated with a striking increase in the blood lactate concentration, a decrease in erythrocyte. As such, we propose that the epidemic of the metabolic syndrome is due in part to fructose-induced hyperuricemia that reduces endothelial NO levels and.

Fructose-Induced Hyperuricemia Is Associated With a Decreased Renal Uric Acid Excretion in Humans

Author information Copyright infuced License information Disclaimer. Urinary UA excretion rate. Furthermore, high-fructose intake over several days is associated with increased fasting UA concentration 1. NO increases blood flow to skeletal muscle and enhances glucose uptake. Animals deficient in endothelial NO develop insulin resistance and other features of the metabolic syndrome.

Exercise prevents fructose-induced hypertriglyceridemia in healthy young subjects. We recently reported that uric acid reduces levels of endothelial nitric oxide NOa key mediator of insulin action.

Effects of supplementation with essential amino acids on intrahepatic lipid concentrations during fructose overfeeding in humans. This study was supported by grant from the Swiss National Foundation for Science and by a grant from Ajinomoto Co. The lack of hyperruricemia in galactosemia patients after galactose ingestion may be explained by the observation that galactose is phosphorylated more slowly than fructose.

The serum Pi level decreased 2. Although the cumulative fructose load was hyoeruricemia 1. In addition, we observed that a serum uric acid level above 5. Open in a separate window. No other potential conflicts of interest relevant to this article were reported. Blood glucose, lactic acid, and fructose levels were significantly increased after fructose, but serum magnesium levels did not change.

This effect appears to be specific for fructose. Am J Physiol Renal Physiol ; National Center for Biotechnology InformationU. Support Center Support Center. This article has been cited by hyeruricemia articles in PMC. Journal List Diabetes Care v. This mechanism may substantially enhance the risk of gout in people who consume high amounts of sugar.

Nutr Metab Lond ; 9: Consistent with this hypothesis is the observation that changes in mean uric acid levels correlate with the increasing prevalence hyperuricemiz metabolic syndrome in the US and developing countries. Fructose-induced hyperuricemia results in endothelial dysfunction and insulin resistance, and might be a novel causal mechanism of the metabolic syndrome.

As such, we propose that the epidemic of the metabolic syndrome is due in part to fructose-induced hyperuricemia that reduces endothelial NO levels and induces insulin resistance. Published online Aug The increasing incidence of obesity and the metabolic syndrome over the past two hypeeuricemia has coincided with a marked increase in total fructose intake. The mean blood inorganic phosphate Pi levels were significantly less than the mean fasting hyperuricemja after fructose.

These effects are generally attributed to an increased UA production, as observed after intravenous fructose administration 2. Please onduced our privacy policy. Allopurinol, rutin, and quercetin attenuate hyperuricemia and renal dysfunction in rats induced by fructose intake: The serum Pi levels decreased less in galactosemic patients after galactose administration than in patients with HFI after fructose infusion.

Studies in humans should be performed to address whether lowering uric acid levels will help to prevent this condition.

These samples were collected while subjects were participating in two clinical trials clinical trial reg.

Parts of this fructoae were presented in abstract form at Experimental BiologyBoston, Massachusetts, 20—24 April F—F [ PubMed ].

Fructose-Induced Hyperuricemia Is Associated With a Decreased Renal Uric Acid Excretion in Humans

Ingestion of a high-fructose meal increases blood uric acid UA concentration in healthy subjects 1. In two patients with HFI the uric acid excretion increased four- to fivefold after fructose administration; the increased uric acid excretion in HFI exceeded hyperuriecmia of normal children. Am J Clin Nutr ; Fructose–unlike other sugars–causes serum uric acid levels to rise rapidly. In two patients with hereditary fructose intolerance HFI the peak blood uric acid levels were Closed symbols represent data collected after 4—6 days of HFrD.
