This NA trial investigates Obstructive Sleep Apnea Syndrome and is currently completed. University of Chicago leads this study, which shows 6 recorded versions since 2006 — indicating limited longitudinal coverage. The change history captured here reflects the iterative nature of clinical trial conduct.

Study Description(click to expand)

We will recruit subjects with OSA about to undergo adenotonsillectomy and collect a blood sample and portion of their tonsils after the induction of general anesthesia. The mononuclear cells will be isolated from both these tissues and stimulated with different markers and cytokines assayed and compared. We will also recruit patients with no symptoms of OSA undergoing unrelated elective surgery and ascertain the absence of OSA by having the parents fill out a sleep questionnaire. We will then collect blood samples from these patients after the induction of anesthesia and examine the cytokine secretion profile and compare it to that of the children with OSA.
