Background:obstructive sleep apnea (OSA) is associated with high prevalence of arterial hypertension (AH), obesity, violation of carbohydrate metabolism and dyslipidemia. However, the effects of CPAP therapy to improve epicardial fat thickness of the OSA patient with AH the are poorly understood and poorly studied.Study objective:the aim of the study was to investigate 12-month effects of CPAP therapy with auto-adaptation to inhalation and exhalation of the OSA patient with AH and metabolic disorders (A-Flex therapy) on epicardial fat thickness (EFT).Methods:to the prospective single-center study were included 310 patients with OSA and AH (273 male, 45,3 ± 10,4 yr.) with apnea-hypopnea index (AHI) >5 events /hour. The night polygraphy study (PG) was performed to calculate AHI, oxygen desaturation index (ODI), mean nocturnal saturation (SpO 2 ) by the rules of American Academy of Sleep Medicine (AASM). The calculation of the epicardial fat thickness (EFT), the size and volume of the heart cavities, left ventricular mass index (LVMI) were performed by two-dimensional echocardiography. Endothelial functionof blood vessels determined by finger test was measured according to peripheral arterial tone (PAT). The reactive hyperemia index (RHI) and augmentation index (AI) was calculated. Optimal level of A-Flex therapy was adjusted at home. AHI, the level of air leakage, average pressure and compliance to CPAP treatment were established in accordance with international requirements.Results:after 3 months of A-Flex therapy we found a significant decrease of HOMA-IR -1,09 (95% Cl from -1,74 to -0,96; P=0,021), decrease AI -10.8% (95% Cl from -13,70 to -4.6; P=0,001), decrease EFT -1,26 mm (95% Cl from -2,2 to -0,95; P=0,001) in mild OSA patients. After 6 months of A-Flex therapy we found a significant decrease of HOMAIR -2,81 (95% Cl from -3,74 to -1,46; P=0,001), decrease AI -15.6 % (95% Cl from -17,23 to -11,75; P=0,001), decrease EFT -2,15mm (95% Cl from -3,2 to -1,5; P=0,001) in moderate OSA patients. After 12 months of A-Flex therapy we found a significant decrease of HOMA-IR -4,22 (95% Cl from -5,36 to -2,35; P=0,001), decrease AI -21,05 % (95% Cl from -26,5 to -17,4; P=0,001), decrease EFT -4,0 mm (95% Cl from-5,8 to -2,7; P=0,001) in severe OSA patients.Conclusions:The 12-month A-Flex therapy in moderate and severe OSA patients with AH has a significant therapeutic effect of stabilization systolic and diastolic blood pressure, level of blood lipids and epicardial fat thickness, level of endothelial dysfunction. The 12-month A-Flex therapy has to able to reduce the risks of cardiovascular events in moderate and severe OSA patients with acute metabolic manifestations.

Obstructive Sleep

Obstructive sleep apnea (OSA) is a common disease, with approximately 3–7% of men and 2–5% of women worldwide suffering from symptomatic OSA. If OSA is left untreated, hypoxia, microarousals and increased chemoreceptor stimulation can lead to complications like hypertension (HT). Continuous positive airway pressure (CPAP) is the most common treatment for OSA, and it works by generating airway patency, which will counteract the apnea or hypopnea. More than one billion people in the world suffer from HT, and the usual treatment is pharmacological with antihypertensive medication (AHM). The focus of this review will be to investigate whether the CPAP therapy for OSA affects HT.

Obstructive Sleep

Pulmonary barotrauma such as pneumothorax (PTX) is a known complication of invasive mechanical ventilation. However, it is uncommonly reported with the use of noninvasive positive pressure ventilation (NPPV) and CPAP (continuous positive airway pressure) therapy. We present a case of a 66-year-old female who presented with chronic dyspnea on exertion secondary to right-sided diaphragmatic hernia. The patient also underwent a home sleep study which suggested obstructive sleep apnea (OSA) for which she was initiated on CPAP. She then underwent surgical repair of her right diaphragmatic hernia. The patient developed pneumothorax three times over the course of the following several months, once on the right side and twice on the left side. The patient’s incidences of PTX had a temporal association with the CPAP initiation. Her CPAP therapy was discontinued permanently after the third occurrence of PTX. With this case report, we highlight the risk of barotrauma with the use of CPAP for OSA. There are very few reported cases of PTX in association with NPPV therapy for OSA. The lung-protective ventilation strategies and limiting the positive airway pressures can help reduce the risk of pulmonary barotrauma with CPAP.

Objectives Adherence to continuous positive airway pressure (CPAP) devices in patients with obstructive sleep apnea (OSA) determines the effectiveness of the treat- ment. Likewise, the assessment of the control of the disease must consider the infor- mation referred by the patient, among other value-based health measures related to the satisfaction of the intervention. The objectives of this study were a) Determine the factors related to adherence to CPAP devices in subjects with OSA affiliated to an insurance company of the healthcare system in Colombia. b) Assess symptom control associated to the disease from the individual ́s perspective and his/her satisfaction with the treatment received. Materials and Methods 1,501 subjects with OSA were surveyed by telephone to explore: sociodemographic factors, habits and lifestyles, use of CPAP and its adverse events, control of the disease, comorbidities, access to care and therapy satisfaction. Using multilevel logistic regression techniques, the influence of the various factors on adherence to CPAP was analyzed, using Stata 13 software. Results Adherence to CPAP therapy was of 58% and the control of symptoms was of 41.7%. The factors that determined the use of CPAP were knowledge on how the device operates, and the disturbances during sleep due to the mask or nasal pad. The- rapy satisfaction was predominantly very good or good. Conclusion Even with moderate adherence values and a good experience with CPAP therapy, symptomatic control of the disease is poor. Many of the factors that affect the use of CPAP are modifiable with a proper approach by the devices ́ service provider.

Plasma Apelin

Apelin is a peptide hormone with cardiovascular and glucose homeostasis properties, and obstructive sleep apnea (OSA) is complicated by cardiovascular and metabolic comorbidities. Plasma apelin has not been previously assessed in OSA. We investigated the response of plasma apelin to a 2-h 75 g oral glucose tolerance test (OGTT) and the effect of 3 months compliant continuous positive airway pressure (CPAP) therapy in 15 obese males with newly diagnosed OSA. Plasma apelin and serum cortisol were recorded 10 minutely, while serum insulin and glucose were measured 30 minutely. Ten subjects had plasma apelin measured at intervals across a 24-h period to investigate for circadian variation in apelin levels, and this was repeated following 3 months compliant CPAP therapy. Fasting (0.342±0.038 vs 0.288±0.024 ng/ml, P=0.04), 30 min (0.399±0.035 vs 0.312±0.036 ng/ml, P=0.007) and 120 min (0.402±0.030 vs 0.259±0.024 ng/ml, P<0.001) apelin levels were reduced following CPAP. The area under curve for apelin OGTT response was lower post-CPAP (44.1±3.3 vs 35.8±2.3 ng/ml per min, P<0.001). Mean OGTT apelin levels showed a significant treatment effect (P=0.006) and a time effect (P<0.001), and the effect of time was different pre- versus post-CPAP (P=0.005). No significant variability in apelin levels existed across the 24-h period at diagnosis. Lower levels were evident overnight following treatment (P=0.004). Improvements in insulin and glucose parameters and reduced cortisol levels were found post-CPAP. In summary, untreated OSA was associated with elevated plasma apelin levels, altered apelin secretory dynamics in response to oral glucose and lack of an apparent circadian variability, which was restored following CPAP.

Abstract Funding Acknowledgements Type of funding sources: Public Institution(s). Main funding source(s): Ministry of Health Czech Republic; identification of organization 65269705 Background Although continuous positive airway pressure (CPAP) is currently still the gold standard for therapy of moderate to severe obstructive sleep apnea (OSA), another alternative or adjunct effective therapeutic options exist. Lifestyle intervention focused on nutrition and weight reduction, regular exercise, sleep hygiene, smoking and alcohol restriction represents a recommended therapeutic strategy for OSA. Though this intervention represents an effective tool for improving objective and subjective parameters of OSA, it’s effectivity depends on components of the intervention, OSA severity and gender. Comprehensive remotely-supervised cardiac rehabilitation (CR) represents possible training intervention in home conditions using elements of telemedicine. Purpose This prospective study aims to investigate the feasibility and effect of a remotely-supervised CR in patients with newly diagnosed OSA with Apnea-Hypopnea Index greater than 15 episodes per hour. Methods This monocentric study is designed as a prospective, parallel, randomised, controlled trial of remotely-supervised 12-week CR in male patients between 40-60 years old with newly diagnosed OSA indicated to CPAP therapy. The sample size is calculated by 0,05 level of significance and 80% statistical power on 25 participants in each group. The Intervention group will undergo comprehensive remotely-supervised CR in home conditions with teleconsultation (contains telecoaching, telemonitoring) via regular phone calls and e-mails at least 1-2 times a week. The intervention will include nutrition, health-related lifestyle and behavioral changes recommendations, and at least 5 times a week 30 minutes of moderate-intensity aerobic training, 10 minutes of inspiratory and expiratory muscle training with breathing device and 10 minutes of oropharyngeal exercise along with individually titrated CPAP therapy. The control group will undergo individually titrated CPAP therapy only. The participants in both groups will go through the following assessments before and after this study: polysomnography, spirometry, anthropometry and body composition examination, laboratory values examination, quality of life questionnaires, Epworth sleepiness scale, 6-min walking test. Conclusions: Comprehensive remotely-supervised CR, as mentioned in this study, may represent an adjunct therapy with a promising future in patients with OSA. The study is occupied with a current issue and can also bring new possibilities and experiences in remote rehabilitation.
