Is this trial a fit for you?

Likely a good fit

Women aged 18-40 with PMOS, diagnosed sleep apnea (AHI >5) by home sleep testing, and BMI under 50.

Probably not a fit

Individuals without PMOS or without sleep apnea, or those with conditions contraindicating CPAP or muscle biopsy may not benefit.

What this trial studies

This pilot interventional study examines how obstructive sleep apnea affects cellular metabolism in PMOS by measuring mitochondrial function in skeletal muscle. Participants will have CPAP therapy applied to assess changes in muscle bioenergetics using high resolution respirometry on muscle biopsies taken with and without CPAP. The study focuses on women aged 18-40 with PMOS and a diagnosed sleep apnea, aiming to generate early data on metabolic responses to CPAP in this multi-systemic condition. Outcomes will inform whether treating sleep apnea could impact the metabolic aspects of PMOS.

Why it matters

Potential benefit: If CPAP improves mitochondrial function, participants may experience better muscle metabolism and overall metabolic health related to PMOS.

How similar studies have gone: Prior studies in related metabolic disorders show CPAP can influence metabolic function, but data in PMOS-specific, CPAP-centered mitochondrial outcomes are limited.
