Keynote Summary: Obstructive sleep apnea(OSA) afflicts up to 1 billion people worldwide. OSA treatment is clearly beneficial yet limited by variable efficacy and/or incomplete adherence to therapy. We have used a mechanistic approach to understand the endotypes underlying OSA with a view towards personalizing treatment based on individual characteristics. Using microRNAs, plasma exosomes, metabolomics and microbiome assessment, we are working to understand basic mechanisms underlying disease to identify which patients are at risk of particular complications, allowing more sophisticated trial designs in the future. We are further using Big Data to assess real world patient outcomes and to implement new technologies to optimize adherence with existing technologies.
