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

Effects of supplementation with essential amino acids on intrahepatic lipid concentrations during fructose overfeeding in humans. No other potential conflicts of interest relevant to this article were reported. Fructose-induced hyperuricemia results in endothelial dysfunction and insulin resistance, and might be a novel causal mechanism of the metabolic syndrome.

The lack of hyperruricemia in galactosemia patients after galactose ingestion may be explained by the observation that galactose is phosphorylated more slowly than fructose. Fructose–unlike other sugars–causes serum uric acid levels to rise rapidly. Ingestion of a high-fructose meal increases blood uric acid UA concentration in healthy subjects 1.

In two patients with hereditary fructose intolerance HFI the peak blood uric acid levels were Animals deficient in endothelial NO develop insulin resistance and other features of the metabolic syndrome.

The serum Pi level decreased 2. The mean blood inorganic phosphate Pi levels were significantly less than the mean fasting value after fructose.

F—F [ PubMed ]. Published online Aug The mean uric acid excretion, expressed as milligrams per fructkse urinary creatinine, was 0.

This study was supported by grant from the Swiss National Foundation for Science and by a grant from Ajinomoto Co. These studies support the hypothesis that fructose-induced hyperuricemia results from degradation of adenosine monophosphate. We recently reported that uric acid reduces levels of endothelial nitric oxide NOa key mediator of insulin action. Journal List Diabetes Care v.

This mechanism may substantially enhance the risk of gout in people who consume high amounts of sugar. It has not been assessed, however, whether UA also increases when fructose is administered as several small drinks instead of one single large load or whether a high-fructose diet HFrD impairs renal UA clearance UAC or fractional excretion UAFE as observed in rats 3.

This article has been cited by other articles in PMC. In addition, we observed that a serum uric acid level above 5. These samples were collected while subjects were participating in two clinical trials clinical trial reg. In two patients with HFI the uric acid excretion increased four- to fivefold after fructose administration; the increased uric acid excretion in HFI exceeded that of normal children.

National Center for Biotechnology InformationU. Allopurinol, rutin, and quercetin attenuate hyperuricemia and renal dysfunction in rats induced by fructose intake: In three patients with galactosemia, increases in blood uric acid levels after galactose ingestion were similar to those in normal children after fructose, but less than those in patients with HFI after fructose.

Because the metabolic hypeuricemia of fructose show significant sex differences, it remains to be assessed whether the same effects are observed in female subjects. NO increases blood flow to skeletal muscle and enhances glucose uptake. These observations suggest that a decreased urinary UA excretion may contribute to fructose-induced hyperuricemia.

This effect appears to be specific for fructose. Although the cumulative fructose load was large 1. Please review our privacy policy. Author information Copyright and License information Disclaimer.

Closed symbols represent data collected after 4—6 days of HFrD. These effects are generally attributed to an increased UA production, as observed after intravenous fructose administration 2. Nutr Metab Lond ; 9: As such, we propose hy;eruricemia the epidemic of the metabolic syndrome is due in part to fructose-induced hyperuricemia that reduces endothelial NO levels and induces insulin resistance.

Consistent with this hypothesis is the observation that changes in mean uric acid levels correlate with the increasing prevalence of metabolic syndrome in the US and developing countries. After the infusion of fructose, 0.

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