Mechanisms of Prediabetic States in Sleep Apnea
The purpose of this study is to better understand how sleep apnea contributes to the development of diabetes.
Substantial evidence indicates that obstructive sleep apnea (OSA) is associated with impaired
glucose metabolism, however, metabolic mechanisms underlying this association remain unclear.
This mechanistic study will determine systemic and cellular metabolic pathways that
contribute to impaired glucose metabolism in obstructive sleep apnea (OSA). Understanding of
how obstructive sleep apnea (OSA) affects glucose metabolism may help identify novel targets
for risk prediction and/or treatment of metabolic impairments beyond continuous positive
airway pressure (CPAP). Obstructive sleep apnea (OSA) patients with prediabetes will be
studied under three in-laboratory conditions in a randomized cross-over design: untreated
condition (obstructive sleep apnea), treated condition (continuous positive airway pressure),
untreated but pharmacologically suppressed lipolysis condition (Niacin). The investigator
will perform whole body and cellular assessments under each study condition.
