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.

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

No other onduced conflicts of interest relevant to this article were reported. Am J Physiol Renal Physiol ; Because the metabolic effects of fructose show significant sex differences, it remains to be assessed whether the same effects are observed in female subjects.

In addition, we observed that a serum uric acid level above 5. Studies in humans should be performed to address whether lowering uric acid levels will help to prevent this condition.

Ingestion of a high-fructose meal increases blood uric acid UA concentration in healthy subjects 1. Allopurinol, rutin, and quercetin attenuate hyperuricemia and renal dysfunction in rats induced by fructose intake: In two patients with hereditary fructose intolerance HFI the peak blood uric acid levels were The serum Pi levels decreased less in induce patients after galactose administration than in patients with HFI after fructose infusion.

We recently reported that uric acid reduces levels of endothelial nitric oxide NOa key mediator of insulin action.

Furthermore, high-fructose intake over several days is associated with increased fasting UA concentration 1. The mean blood inorganic phosphate Pi levels were significantly less than the mean fasting value after fructose.

Blood glucose, lactic acid, and fructose levels were significantly increased hyperuricrmia fructose, but serum magnesium levels did not change. Readers may use this article as long as the work is properly cited, the use is educational and not for profit, and the work is not altered.

Effects of supplementation with essential amino acids on intrahepatic lipid concentrations during fructose overfeeding in humans. Published online Aug 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. The serum Pi level decreased 2. Parts of this study were presented in abstract form at Experimental BiologyBoston, Massachusetts, 20—24 April Open hperuricemia a separate window.

These studies support the hypothesis that fructose-induced hyperuricemia results from degradation of adenosine monophosphate. Support Center Support Center. The increasing incidence of obesity and the metabolic syndrome over the past two decades has coincided with a marked increase in total fructose intake. These observations suggest that a decreased urinary UA excretion may contribute to fructose-induced hyperuricemia. These indkced are generally attributed to an increased UA production, as observed after intravenous fructose administration 2.

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.

Exercise prevents fructose-induced hypertriglyceridemia in healthy young subjects. In two patients with Hyperuricemiz the uric acid excretion increased four- to fivefold after fructose administration; the increased uric acid excretion in HFI exceeded that of normal children.

Animals deficient in endothelial NO develop insulin resistance and other features of the metabolic syndrome. This article has been cited by other articles in PMC.
