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.

In addition, we inruced that a serum uric acid level above 5. These studies support the hypothesis that fructose-induced hyperuricemia results from degradation of adenosine monophosphate. Animals deficient in endothelial NO develop insulin resistance and other features of the metabolic syndrome.

Open in a separate window. Blood glucose, lactic acid, and fructose levels were significantly increased after fructose, but serum magnesium levels did not change. F—F [ PubMed ]. Exercise ijduced fructose-induced hypertriglyceridemia in healthy young subjects. This effect appears to be specific for 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.

Effects of supplementation with essential amino acids on intrahepatic lipid concentrations during fructose overfeeding in humans. Urinary UA excretion rate. The serum Pi level decreased 2.

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

The mean blood inorganic phosphate Pi levels were significantly less than the mean fasting value after fructose. In two patients with HFI the uric acid excretion increased four- to insuced after fructose administration; the increased uric acid excretion in HFI exceeded that of normal children.

Nutr Metab Lond ; 9: Am J Clin Nutr ; These effects are generally attributed to an increased UA production, as observed after intravenous fructose administration 2. Acknowledgments This study was supported by grant from the Swiss National Foundation for Science and by a grant from Ajinomoto Co. Parts of this study were presented in abstract form at Inducd BiologyBoston, Massachusetts, 20—24 April Am J Physiol Renal Physiol ; The serum Pi levels decreased less in galactosemic patients after galactose administration than in patients with HFI after fructose infusion.

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 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. Closed symbols represent data collected after 4—6 days of HFrD.

Fructose–unlike other sugars–causes serum uric acid levels to rise rapidly.

Furthermore, high-fructose intake over several days is associated with increased fasting UA concentration 1. National Center for Biotechnology InformationU.

These observations suggest that a decreased urinary UA excretion may contribute to fructose-induced hyperuricemia. Although the cumulative fructose load was large 1.

Journal List Diabetes Care v. No other potential conflicts of interest relevant to this article were reported. Published online Aug 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.

Because the metabolic effects 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. Fructoze in humans should be performed to address whether lowering uric acid levels will help to prevent this condition.

In two patients with hereditary fructose intolerance HFI the peak blood uric acid levels were As such, we propose that the epidemic of the metabolic syndrome is due in part to fructose-induced hyperuricemia that reduces endothelial Hyperuricrmia levels and induces insulin resistance.

Fructose-induced hyperuricemia results in endothelial dysfunction and insulin resistance, and might be a hyperueicemia causal mechanism of the metabolic syndrome.

This mechanism may substantially enhance the risk of gout in people who consume high amounts of sugar. This article has been cited by other articles in PMC.
