The Relation between Fructose-Induced Metabolic Syndrome and Altered Renal Haemodynamic and Excretory Function in the Rat

الملخص EN

This paper explores the possible relationships between dietary fructose and altered neurohumoral regulation of renal haemodynamic and excretory function in this model of metabolic syndrome.

Fructose consumption induces hyperinsulinemia, hypertriglyceridaemia, insulin resistance, and hypertension.

The pathogenesis of fructose-induced hypertension is dubious and involves numerous pathways acting both singly and together.

In addition, hyperinsulinemia and hypertension contribute significantly to progressive renal disease in fructose-fed rats.

Moreover, increased activity of the renin-angiotensin and sympathetic nervous systems leading to downregulation of receptors may be responsible for the blunted vascular sensitivity to angiotensin II and catecholamines, respectively.

Various approaches have been suggested to prevent the development of fructose-induced hypertension and/or metabolic alteration.

In this paper, we address the role played by the renin-angiotensin and sympathetic nervous systems in the haemodynamic alterations that occur due to prolonged consumption of fructose.
