简要总结

The investigators plan to recruit 140 patients (35 subjects in each group) over a period of 18 months in a prospective study of matched/paired case-control subjects across the four groups to measure the 5-year risk of developing DM2 in each group and if knowledge of the 5-year risk of developing diabetes will affect continuous positive airway pressure (CPAP) compliance. The study will have four arms: 1) patients who have newly-diagnosed OSA requiring CPAP therapy without diabetes and are given the result of the diabetes risk score; 2) patients who have newly-diagnosed OSA requiring CPAP therapy without diabetes and are not given the result of the diabetes risk score; 3) age, sex, and BMI-matched controls without OSA or diabetes; 4) age, sex, BMI, and OSA severity matched patients on CPAP therapy for OSA. The investigators will document that the patients are compliant with CPAP based on review of SD card data recorded by the CPAP machine. Each patient will have serum drawn for the biomarker panel as well as the standard diagnostic measures of DM2 (oral glucose tolerance test (OGTT) upon enrollment in the study. An Epworth Sleepiness Score, BMI, neck and waist circumference, smoking history, blood pressure, and other standard vital signs will also be collected.

There will be no follow-up of the study subjects in groups 3 and 4 and their participation in this study is completed after Visit 1. Groups 1 and 2 will be followed for 6 months after enrollment to assess whether or not there is any change in CPAP compliance as measured by SD card.

详细描述

A total of 140 subjects will be recruited (35 subjects with newly-diagnosed obstructive sleep apnea (OSA) without diabetes who will be told their 5-year risk of developing diabetes mellitus type 2 (DM2) prior to starting CPAP therapy, 35 subjects with newly-diagnosed OSA without diabetes who will not be told their 5-year risk of developing DM2 prior to starting continuous positive airway pressure (CPAP) therapy, 35 healthy subjects without OSA or diabetes, and 35 subjects with OSA > 12 months on CPAP therapy). The patients who are newly-diagnosed with OSA will need to be assessed to require CPAP therapy by their treating physician. The investigators will use "A" (ex: A001) before the subject numbers of those subjects newly-diagnosed OSA requiring CPAP therapy without diabetes and are given the result of the diabetes risk score (group 1); and "B" (ex: B001) before the subject numbers of those subjects who have newly-diagnosed OSA requiring CPAP therapy without diabetes and are not given the result of the diabetes risk score (group 2). The investigators will use a "C" (ex: C001) before the subject numbers of the healthy subjects (age, sex, and BMI-matched controls) without OSA or diabetes (group 3). The investigators will use a "D" (ex: D001) before the subject numbers of the (age, sex, BMI, and OSA severity matched) patients on CPAP therapy for OSA (group 4).

Screening Visit:

  • Obtain signed Informed Consent document and HIPAA Authorization (research-driven)
  • Women of child bearing potential will have a serum pregnancy test (5-10 milliliters (mls), approximately 1-2 teaspoons of blood) (research-driven).
  • Review of sleep study data and SD card (flash memory card) data as appropriate to assess for good CPAP compliance as defined by average daily use of >= 4 hours for at least 5 days/week for the 30 days preceding enrollment (standard of care)
  • Patients will be told to fast for at least 10 hours prior to Visit 1.
