  Purpose

The overall goal of the proposed protocol is to rigorously test the hypothesis that CPAP treatment has beneficial effects on glycemic control in patients with both type 2 diabetes (T2DM) and obstructive sleep apnea (OSA). If our hypothesis were to be proven, this would imply that CPAP treatment of OSA in patients with T2DM is an essential component of their glycemic control. The proposed work is thus expected to provide additional preventive and therapeutic approaches in the management of millions of patients with T2DM.

Primary Outcome Measures:
  • 24 hour hormonal blood sampling [ Time Frame: after 1 week of CPAP therapy in the laboratory ] [ Designated as safety issue: No ]
    24 hour hormonal blood sampling will include frequent sampling of glucose, insulin, c-peptide levels at baseline and after one week of active or placebo CPAP therapy

  • 48 hours of Continuous Glucose Monitoring [ Time Frame: after 1 week of active or placebo CPAP therapy in the laboratory ] [ Designated as safety issue: No ]
    Continuous Glucose monitoring will provide interstitial glucose levels for 48 hours at baseline and after one week of active or placebo CPAP therapy

  • 24 hours of continuous glucose monitoring [ Time Frame: after 3 months of active CPAP therapy at home ] [ Designated as safety issue: No ]
    Continuous Glucose monitoring will provide interstitial glucose levels for 24 hours after 3 months of active CPAP therapy at home

Intervention Details:
