Sleep Apnea Biomarkers and Adherence to Continuous Positive Airway Pressure (BIOSA)
2026년 8월 26일 업데이트: Bughin Francois, Clinique du Millenaire
Impact of Obstructive Sleep Apnea Biomarkers on Adherence to Continuous Positive Airway Pressure: Role of Pulse Wave Amplitude Drop Index, Hypoxic Burden, and Heart Rate Variability
Obstructive sleep apnea (OSA) is commonly assessed using the apnea-hypopnea index, although this measure does not fully reflect cardiovascular risk or the physiological impact of the disease. Emerging biomarkers, including sleep apnea-specific hypoxic burden, pulse wave amplitude drop index, and heart rate response, may provide additional information on cardiovascular vulnerability.
This prospective multicenter observational study will investigate the association between these biomarkers, measured from the diagnostic sleep study, and adherence to continuous positive airway pressure (CPAP) therapy after three months. Symptoms, quality of life, clinical characteristics, and changes in biomarkers under continuous positive airway pressure will also be evaluated.
연구 개요
상세 설명
This is a prospective, longitudinal, multicenter observational cohort study involving adults with newly diagnosed obstructive sleep apnea for whom continuous positive airway pressure therapy is indicated as part of routine clinical care.
At baseline, demographic and clinical characteristics, medical history, current treatments, symptom questionnaires, and results from diagnostic respiratory polygraphy or polysomnography will be collected. Hypoxic burden, pulse wave amplitude drop index, and heart rate response will be calculated from the initial sleep recording. Continuous positive airway pressure will be prescribed according to standard clinical practice.
At 12 weeks, with a permitted window of plus or minus four weeks, adherence data will be obtained from the continuous positive airway pressure device. Clinical information and questionnaires will be collected again. Participants requiring a follow-up sleep study as part of routine care may undergo respiratory polygraphy or polysomnography while receiving continuous positive airway pressure, allowing assessment of biomarker changes under treatment.
The principal analysis will examine associations between baseline biomarkers and continuous positive airway pressure adherence. Secondary analyses will assess biomarker distributions according to clinical characteristics, associations with symptoms and quality of life, and changes in biomarkers during treatment.

Daytime Sleepiness Assessed by the Epworth Sleepiness Scale
기간: Baseline and 3 months
|
Daytime sleepiness will be assessed using the Epworth Sleepiness Scale at baseline and 3 months after CPAP initiation.
The total score ranges from 0 to 24, with higher scores indicating greater daytime sleepiness and therefore a worse outcome.
The change in total score between baseline and 3 months will be evaluated.

Health-Related Quality of Life Assessed Using the EuroQol 5-Dimension 5-Level Questionnaire
기간: baseline and 3 months
|
Health-related quality of life will be assessed using the EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L) at baseline and 3 months after CPAP initiation.
The EQ-5D-5L evaluates five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.
Each dimension has five response levels, ranging from 1 (no problems) to 5 (extreme problems or inability to perform the activity).
Responses will be converted into an EQ-5D-5L utility index using the French value set.
Index values range from -0.525 to 1, with higher values indicating better health-related quality of life.
The change in the utility index between baseline and 3 months will be evaluated.
