2. Do You Use CPAP For Sleep Apnea?

Researchers at Johns Hopkins are looking for looking for people who regularly use CPAP for sleep apnea to study differences in metabolism, both on and off therapy. During one visit, you will wear CPAP all night, and on another visit you will wear a nasal dilator strip instead of CPAP. We are studying changes in glucose and fat levels in the blood, and if nasal dilator strips can improve sleep apnea or metabolism.

You may be eligible to participate in this study if you:

  • Are 20-75 years old
  • Have obstructive sleep apnea (breathing pauses more than 20 times per hour)
  • Are used to sleeping comfortably with CPAP and willing to switch to nasal dilator strips for a few days
  • Do NOT have uncontrolled high blood pressure
  • Do NOT have diabetes that requires use of insulin
  • Do NOT take certain medications such as niacin or clonidine
  • Are NOT pregnant

The study includes:

  • Two overnight sleep studies in the laboratory, stopping CPAP for a few nights
  • Completion of interviews and questionnaires
  • IV placement and blood samples
  • Diabetes tests, a urine sample and a bone scan

Participants can earn up to $400. To find out if you are eligible, please contact us at 410-550-1816 and ask about the “MIIC Study."
