Extracellular microRNA: Biomarkers of Endothelial Dysfunction in Obese Adolescents & Adults With Obstructive Sleep Apnea
Extracellular Micro RNA (miR) (Extracellular Vesicle (EV)-Associated & Non-EV-associated miRs) Identify and Mediate Endothelial Dysfunction in Obesity and Obstructive Sleep Apnea in Adolescents & Young Adults
연구 개요
상세 설명
Investigators will randomize 100 OSA patients (age 13-21) to receive either continuous positive airway pressure (CPAP) plus baseline diet/exercise (n=50) or medical management (intensive diet and exercise; n=50). Only children in whom adenotonsillectomy is contraindicated (morbid obesity, history of adenotonsillectomy, lack of adenotonsillar hypertrophy) will be included. Investigators will conduct a randomized prospective comparative effectiveness study to assess the impact of treatment on OSA on endothelial function (peripheral arterial tonometry-EndoPAT). In addition to diagnostic polysomnography and EndoPAT at baseline, EV (extracellular vesicle) and non EV derived miR 92a/miR 210 concentrations, inflammatory cytokines concentrations, and body anthropometry will be measured. Following 3 mos of therapy and after 6mos of therapy, investigators will re-evaluate EndoPAT, EV and non EV derived miR 92a/miR 210 concentrations, inflammatory cytokines, and body anthropometry.
Throughout the study, investigators will maintain weekly telephone contact and monthly face-to-face visits as per standard of care in both groups to ensure ongoing success. In the medical management group (intensive diet and exercise), diet and exercise will be tracked by maintaining weekly telephone contact and monthly face-to-face visits with a registered dietician. For the CPAP group, investigators will also maintain weekly telephone contact and monthly face-to-face visits with a sleep technician to review mask fitting, and adherence reports, to optimize adherence to CPAP therapy.
Following completion at six months, polysomnography will be repeated.

실험적: CPAP
This arm will consist of patients with obstructive sleep apnea who will be asked to use CPAP nightly to treat their OSA for six months
|
This device delivers air pressure non invasively through a mask to stent open the upper airway to prevent obstruction during sleep.
This is an FDA approved device that has been used for several decades to treat OSA.

IPD 계획 설명
Intellectual property and data generated under this project will be administered in accordance with both University and NIH policies, including the NIH Data Sharing Policy and Implementation Guidance of March 5, 2003.
As a part of this application will involve human subjects, investigators believe that the rights and privacy of people who will participate in the research project must be protected at all times. In case other investigators express interest in working with the data, every effort will be made to provide the data to them free of identifiers. However, such endeavors will have to be individually considered and also approved by the University of California (UC) San Diego Human Research Protection Program before any commitments can be made.
