Section I. Funding Opportunity Description

The purpose of this FOA is to invite applications that investigate the mechanisms mediating the interactions between sleep and diabetes-related metabolism using deep metabolic phenotyping approaches in healthy human populations and those with metabolic and/or sleep disorders.diabetes

Large, epidemiological studies support an association between disrupted sleep [sleep deprivation, sleep fragmentation, short sleep, and obstructive sleep apnea (OSA)] and dysregulated metabolism, specifically increased body weight and/or glucose intolerance. Small studies conducted primarily in healthy control subjects also indicate that laboratory-induced sleep deprivation impairs insulin sensitivity and may have effects on other metabolic indices that impact insulin sensitivity and glucose tolerance including circulating inflammatory markers, lipid metabolism, autonomic nervous system activity and food intake.  Small studies conducted in clinical populations such as individuals with OSA, also show a relationship between OSA and impaired glucose tolerance or decreased insulin sensitivity relative to matched controls. However, while small studies show treatment of OSA generally seems to improve insulin sensitivity, there are minimal effects on glucose tolerance.

The mechanisms mediating impairment of glucose metabolism and insulin sensitivity by sleep disruption are not known. Current animal models of sleep disruption often do not replicate the human sleep disorders and thus limit translation of findings from rodents into humans. To date, human studies examining the effects of sleep disruption on diabetes related metabolism have not included in-depth metabolic phenotyping that would contribute to elucidating potential mediators or to identifying the tissue site (or sites) associated with disrupted metabolism. Furthermore, the majority of studies on human sleep and glucose metabolism have been conducted in healthy subjects whose sleep has been disrupted by various interventions in a controlled laboratory setting. Few studies have attempted to treat sleep disorders in populations with metabolic or sleep disorders and demonstrate improvements in glucose homeostasis or diabetes-related metabolism. Identifying a population with a known metabolic or sleep disorder and being able to demonstrate that a therapeutic sleep intervention can ameliorate abnormalities in glucose or diabetes-related metabolism would have important clinical implications.

This FOA invites applications which propose in-depth metabolic phenotyping in carefully selected clinical populations to determine how changes in sleep (improvements or disruptions) influence diabetes-related metabolism. Applications should systematically test a physiological model with the goal of elucidating possible mediators of the reported effects of sleep on glucose metabolism. Applications that propose therapeutic interventions to improve sleep and determine the consequences on diabetes-related metabolism must have preliminary data demonstrating that the proposed method for improving sleep is actually efficacious.
