Bozic J, et al. - In patients with moderate and severe obstructive sleep apnea (OSA) vs healthy controls, researchers assessed plasma adropin, systemic inflammation biomarker levels, and glucose metabolism parameters. Participants in the study were 50 male patients with OSA and 25 age- and sex-matched controls. Researchers reported that plasma adropin concentrations are significantly associated with indices of disease severity in patients with OSA. Findings from the present study suggested that adropin potentially plays an important role in the complex pathophysiology of the disease.
