Clinical Trial Summary

Patients with treatment-naive obstructive sleep apnea (OSA) who need continuous positive airway pressure (CPAP) therapy on clinical basis are included as well as healthy controls without OSA. 15 cc peripheral venous blood is drawn on the date of diagnosis of OSA and 3-6 months after CPAP therapy. Granulocytes are harvested and tested for its function, such as phagocytosis, reactive oxygen species (ROS) production and bacteria-killing ability.


Clinical Trial Description

Patients with treatment-naive obstructive sleep apnea (OSA) who need continuous positive airway pressure (CPAP) therapy on clinical basis are included. Healthy controls without OSA are enrolled, too. 15 cc peripheral venous blood is drawn on the date of diagnosis of OSA and 3-6 months after CPAP therapy (not given to controls). Granulocytes are harvested and tested for its function, such as phagocytosis, reactive oxygen species (ROS) production and bacteria-killing ability. ;
