Circulating levels of adiponectin, orexin-A, ghrelin and the antioxidant paraoxonase-1 in metabolic syndrome

Minerva Med. 2012 Aug;103(4):323-9.

Abstract

Aim: Metabolic syndrome (MS) is a disorder consisting of various abnormalities such as dyslipidemia, obesity, hypertension and hyperglycemia. Over the past two decades, the prevalence of MS has greatly increased, and it has become a global health problem. We measured and compared plasma concentrations of adiponectin, orexin-A, ghrelin and the antioxidant paraoxonase-1 (PON1) between patients with metabolic syndrome (MS) and healthy controls.

Methods: A total of 87 patients (46 women, 41 men) with MS and 40 healthy controls (21 women, 19 men) with a BMI less than 25 kg/m2 were enrolled in the study. The plasma concentrations of the adiponectin, orexin-A, ghrelin and PON1 were measured by ELISA.

Results: Plasma concentrations of Orexin-A were significantly higher in patients with MS than controls (P<0.001). However, plasma concentrations of adiponectin, ghrelin and PON1 were significantly lower in patients with MS compared to controls (P<0.001, P<0.001 and P<0.001, respectively).

Conclusion: Our data confirmed the previous findings that plasma concentrations of orexin-A is higher than controls, however plasma concentrations of PON1, ghrelin and adiponectin are lower compared to controls.
