Clinical Trial Summary

It was aimed to investigate the effect of expiratory muscle strength training (EMST) applied at different intensities on systemic inflammation and oxidative stress in patients with moderate obstructive sleep apnea syndrome (OSAS). In the study, 32 male patients diagnosed with moderate OSAS will be included in the study. Participants will then be divided into 2 groups by block randomization. In the three-blind planned study; the first group will receive high-intensity %60 maximum expiratory pressure (MEP) EMST training, and the second group will be given low-intensity 30% of MEP, EMST training for 12 weeks. Disease-related symptoms, disease severity apnea-hypopnea index (AHI), oxidative stress index (OSI) and systemic inflammation level, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and fatigue severity will be evaluated before and after the study.

Description:

Primary outcome measures are; disease severity, oxidative stress index and systemic inflammation. Secondary outcome measurements are; disease-related symptoms, exercise capacity, respiratory muscle strength, sleep quality, daytime sleepiness, and severity of fatigue.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Disease severity	Polysomnography recordings will be taken especially sleep efficiency and apnea-hypopnea index (AHI). Higher sleep efficiency and lower AHI values shows that patient have better status and lower disease severity	2 days
Primary	Oxidative stress-1	TAS:Venous blood sample will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning after an overnight fast and will be analyzed with a colorimetric kit.	5 days
Primary	Systemic inflammation-1	CRP:biochemistry laboratory will work on the Abbott Architect C4000 (USA) clinical chemistry autoanalyzer.	5 days
Primary	Systemic inflammation-2	TNF-a:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.	5 days
Primary	Systemic inflammation-3	IL10:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.	5 days
Primary	Systemic inflammation-4	IL-6:After an overnight fast, venous blood samples will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning and analyzed with the ELISA kit.	5 days
Primary	Oxidative stress-2	TOS:Venous blood sample will be taken from the forearms of the patients in a 5 mL gel biochemistry tube with serum separator between 8.00-11.00 in the morning after an overnight fast and will be analyzed with a colorimetric kit.	5 days
Secondary	Exercise capacity	6 minute walking testing (6MWT):The primary outcome is the distance covered in meters or converted measure (such as feet) over 6 minutes. To measure functional aerobic capacity or general fitness, this test may be used in conjunction with VO2 testing.	2 days
Secondary	Maximal inspiratory and expiratory muscle strength	Maximal inspiratory and expiratory muscle strength will be evaluated with mouth pressure device.	2 days
Secondary	Daytime sleepiness	Epworth Sleepiness Scale . Minimum and maximum scores: 0-24. The higher Epworth Sleepiness Scale score means the higher that person's average sleep propensity in daily life , or their 'daytime sleepiness'	2 days
Secondary	Fatigue severity.	Fatigue Severity Scale (FSS)Minimum and maximum scores: 0-7. FSS scores higher than 4 shows high intensity fatigue perception	2 days
Secondary	Sleep quality	The Pittsburgh Sleep Quality Index (PSQI). Minimum and maximum scores: 0-21. Higher PSQI scores show worse sleep quality.	2 days
