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.

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

Support Center Support Center. These observations suggest that a decreased urinary UA excretion may contribute to fructose-induced hyperuricemia. Allopurinol, rutin, and quercetin attenuate hyperuricemia and renal dysfunction in rats induced by fructose fryctose NO increases blood flow to skeletal muscle and enhances glucose uptake. 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.

Exercise prevents fructose-induced hypertriglyceridemia in healthy young subjects.

These samples were collected hperuricemia subjects were participating in two clinical trials clinical trial reg. After the infusion of fructose, 0.

In three patients with galactosemia, increases induce 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. The increasing incidence of obesity and the metabolic syndrome over the past two decades has coincided with a marked increase in total fructose intake.

The serum Pi levels decreased less in galactosemic patients after galactose administration than in patients with HFI after fructose infusion.

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. Acknowledgments This study was supported by grant from the Swiss National Foundation for Science and by a grant from Ajinomoto Co.

Although the cumulative fructose load was large 1. These effects are generally attributed to an increased UA production, as observed after intravenous fructose administration 2. The mean uric acid excretion, expressed as milligrams per mg urinary creatinine, was 0. Fructose–unlike other sugars–causes serum uric acid levels to rise rapidly. Effects of supplementation with essential amino acids on intrahepatic lipid concentrations during fructose overfeeding in humans.

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 mean blood inorganic phosphate Pi levels were significantly less than the mean fasting value after fructose. This study was supported by grant from the Swiss National Foundation for Science and by a grant from Ajinomoto Co.

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

Parts of this study were presented in abstract form at Hyperuricwmia BiologyBoston, Massachusetts, 20—24 April No other potential conflicts of interest relevant to this article were reported. Nutr Metab Lond ; 9: Ingestion of a high-fructose meal increases blood uric acid UA concentration in healthy subjects 1.

Animals deficient in endothelial NO develop insulin resistance and other features of the metabolic syndrome. In two patients with hereditary fructose intolerance HFI the peak blood uric acid levels were These studies support the hypothesis hyperuriceemia fructose-induced hyperuricemia results from degradation of adenosine monophosphate.

Published online Aug Journal List Diabetes Care v. 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. In addition, we observed that a serum uric acid level above 5. F—F [ PubMed ]. Closed symbols represent data collected after 4—6 days of HFrD.

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

The serum Pi level decreased 2. This mechanism may substantially enhance the risk of gout in people who consume high amounts of sugar. Readers may use this article as long as the fructowe is properly cited, the use is educational and not for profit, and the work is not altered.

Open in a separate window. Because the metabolic effects of fructose show significant sex differences, it remains to be assessed whether the same effects are observed in female subjects. 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.
