Abstract
Purpose
Inflammation and oxidative stress play important roles in the pathogenesis of obstructive sleep apnoea syndrome (OSAS). Omentin is expressed in visceral adipose tissue and is associated with the inflammatory response. The aim of this study was to assess the relationship between OSAS and omentin based on a comparison of its serum levels at baseline and after 3 months of continuous positive airway pressure (CPAP) therapy.
Methods
Ninety-six newly diagnosed OSAS patients and 31 non-apnoeic controls were enrolled in this study. Blood samples were obtained in the morning after polysomnography. Within the OSAS group, 30 patients were started on CPAP therapy and then reassessed clinically, including a blood test for serum omentin and other biochemical analysis, at 3 months.
Results
Serum omentin levels were significantly lower in the OSAS group than in the control group (27.7 ± 7.6 and 42.5 ± 5.2 ng/mL, P < 0.001). In the subgroup analysis, omentin concentrations were significantly lower in patients with severe OSAS than in those with mild/moderate OSAS (P < 0.001). Circulating omentin levels were significantly correlated with the apnoea–hypopnoea index (AHI), mean SaO2, oxygen desaturation index, and serum C-reactive protein levels. Treatment with CPAP resulted in a significant increase in circulating omentin levels after 3 months, from 22.7 ± 1.4 to 41.2 ± 3.3 ng/mL (P < 0.001).
Conclusions
OSAS is associated with low serum omentin levels, and these levels can be reversed by effective CPAP treatment.

Comments
Obesity is a problem commonly associated with people diagnosed with obstructive sleep apnoea syndrome (OSAS). It is known that omentin expressed in visceral adipose tissue is associated with the inflammatory response, which in turn has role in the pathogenesis of OSAS. The results of this study which included 30 patients with moderate-severe OSAS treated with CPAP suggest that the therapy can positively influence serum omentin levels and thus have the potential to benefit vascular health, which is at risk in people with OSAS.
