Assessing the Risk of Developing Type II Diabetes Using Serum Biomarkers in Patients Diagnosed With Obstructive Sleep Apnea

Completed · Not applicable

Conditions studied: Obstructive Sleep Apnea, Diabetes Mellitus

In brief

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.
