<h4>Background</h4>Obstructive sleep apnoea syndrome (OSAS) is associated with several chronic diseases, including erectile dysfunction (ED). The association of OSAS and ED is far more common than might be found by chance; the treatment of OSAS with non-invasive positive airway pressure therapy is associated with improvement of respiratory symptoms, and may contribute to the improvement of associated conditions, such as ED.<h4>Objectives</h4>To assess the effectiveness and acceptability of non-i ...[more]

Project description:ObjectivesObstructive sleep apnea (OSA) is among the least studied risk factors for erectile dysfunction (ED). We aimed to determine ED prevalence in newly-diagnosed OSA patients, describe their main characteristics and assess continuous positive airway pressure (CPAP) effects on ED.MethodsCross-sectional study assessing ED prevalence in OSA patients and open-label, parallel, prospective randomized controlled trial evaluating 3-month CPAP treatment effects on sexual function, satisfaction, and psychological, hormonal and biochemical profiles. Male patients newly diagnosed with moderate/severe OSA (apnea-hypopnea index >20 events·h-1), aged 18-70 years, attending the sleep unit of a Spanish hospital during 2013-2016 were considered. A total of 150 patients were recruited (75 randomized ED patients). ED was defined as scores <25 on International Index Erectile Function 15 test. Wilcoxon's matched-pairs signed-ranks and rank-sum tests were used.ResultsED prevalence was 51%. Patients with ED were older (p<0.001), had greater waist-to-hip ratios (p<0.001), were more frequently undergoing pharmacological treatment (p<0.001) and had higher glucose levels (p = 0.024) than non-ED patients. Although significant increases in erectile function (mean(SD) change: +4.6(7.9); p = 0.002), overall satisfaction (+1(2.2); p = 0.035), and sexual satisfaction (+2.1(4.3); p = 0.003) were found after CPAP treatment, only differences in sexual satisfaction (p = 0.027) and erectile function (p = 0.060) were found between study arms. CPAP treatment did not impact psychological, hormonal or biochemical profiles.ConclusionsThis study confirmed the relationship between OSA and ED, suggesting the potential usefulness of ED screening in OSA patients, but could not determine conclusively whether CPAP is an effective stand-alone ED treatment, regardless of positive results on sexual satisfaction.Trial registrationClinicalTrials.gov NCT03086122.

Project description:Obstructive sleep apnoea (OSA) is a common disease that can be treated with continuous positive airway pressure (CPAP). CPAP tolerance may be associated with its compliance. Even though there are several predictors for good CPAP compliance, there are limited data available on the correlation between CPAP compliance and OSA symptoms. This study aimed to evaluate this correlation. We conducted a cross-sectional study and enrolled adult patients diagnosed with OSA through polysomnography who had experience using a CPAP machine. A self-report questionnaire was used to evaluate CPAP compliance and study variables. Predictors of CPAP compliance were analysed using stepwise multivariate logistic regression analysis. There were 68 patients with OSA who completed the questionnaire during the study period. Of those, 14 (20.59%) exhibited good CPAP compliance. Only fatigue as a symptom was an independent factor associated with good CPAP compliance, with an adjusted odds ratio of 5.380 (95% CI 1.274–22.719). In conclusion, fatigue was the only symptom associated with good CPAP compliance in patients with OSA. Fatigue improves CPAP compliance in OSA patientshttps://bit.ly/2R635zR

Project description:Obstructive sleep apnoea (OSA) syndrome is characterised by the presence of apnoea or obstructive hypopnoea during sleep, accompanied by hypoxia. It is estimated that the syndrome affects approximately 10% of men and 15% of women. Diagnosis and treatment rates have increased in recent years, but the condition remains undiagnosed in a high percentage of patients. Recent evidence suggests that OSA may increase the risk of cardiovascular disease. The relationship between OSA and cardiovascular disease can be explained, at least in part, by the coexistence of cardiovascular risk factors in the two pathologies, such as age, overweight, smoking and sedentary lifestyle. However, OSA has been independently associated with the risk of developing hypertension, cerebrovascular disease, ischaemic heart disease, heart failure and arrhythmias. Clinical trials that have evaluated the efficacy of continuous positive airway pressure (CPAP) treatment in primary and secondary cardiovascular prevention have not demonstrated a significant reduction in the incidence or recurrence of cardiovascular events. This article analyses the relationship between OSA and cardiovascular risk and discusses recent clinical trials on the efficacy of CPAP in primary and secondary cardiovascular prevention.

Project description:A subgroup of children with obstructive sleep apnoea (OSA) requires treatment with continuous positive airway pressure (CPAP). This study's aims were: 1) to determine if the optimal CPAP for the treatment of OSA in children correlates with body mass index (BMI); 2) to determine the correlation between polysomnographic variables and optimal CPAP in children with OSA; and 3) to develop a CPAP predictive equation for children with OSA. This was a retrospective study of children with OSA who underwent CPAP titration studies. Patients with craniofacial abnormalities (except Down syndrome) and neuromuscular diseases were excluded. Polysomnograms were done using Sandman Elite. Correlations between optimal CPAP, clinical and polysomnographic variables were analysed. A multivariable linear regression model for optimal CPAP was developed. 198 children (mean±sd age 13.1±3.6 years) were studied. Optimal CPAP had a significant positive correlation with age (rho=0.216, p=0.002), obstructive apnoea-hypopnoea index (rho=0.421, p<0.001), 3% oxygen desaturation index (rho=0.417, p<0.001), rapid eye movement respiratory disturbance index (rho=0.378, p<0.001) and BMI z-score (rho=0.160, p=0.024); and a significant negative correlation with arterial oxygen saturation measured by pulse oximetry nadir (rho= -0.333, p<0.001). The predictive equation derived was:Optimal CPAP (cmH2O)=6.486+0.273·age (years)-0.664·adenotonsillectomy(no=1, yes=0)+2.120·Down syndrome (yes=1, no=0)+0.280·BMI z-score. The equation developed may help to predict optimal CPAP in children with OSA. Further studies are required to validate this equation and to determine its applicability in different populations.

Project description:BackgroundLittle is known about the treatment burden experienced by patients with obstructive sleep apnoea (OSA) who use continuous positive airway pressure (CPAP) therapy.Participants18 patients (33.3% males, mean age 59.7±11.8 years) with OSA who use CPAP therapy were interviewed.MethodsPatients treated with CPAP for OSA at a tertiary hospital outpatient clinic in Sydney, Australia, were invited to participate in an interview in person or via phone. Semi-structured interviews were used to explore the treatment burden associated with using CPAP. The interviews were recorded, transcribed, and analysed using NVivo 12 qualitative analysis software.ResultsFour categories of OSA-specific treatment burden were identified: healthcare tasks, consequences of healthcare tasks, exacerbating and alleviating factors of treatment burden. Participants reported a significant burden associated with using CPAP, independently of how frequently they used their device. Common sources of their treatment burden included attending healthcare appointments, the financial cost of treatment, lifestyle changes, treatment-related side effects and general discomfort.ConclusionsThis study demonstrated that there is a significant treatment burden associated with the use of CPAP, and that treatment non-adherence is not the only consequence of treatment burden. Other consequences include relationship burden, stigma and financial burden. It is important for physicians to identify other negative impacts of treatment burden in order to optimise the patient experience.

Project description:ObjectivesTo evaluate the effect of obstructive sleep apnoea syndrome (OSAS) and continuous positive airway pressure (CPAP) therapy on choroidal structural changes and choroidal vascularity index (CVI) in patients with OSAS.MethodsChoroidal structural changes in patients with OSAS immediately after diagnosis and 12 months after CPAP treatment were evaluated and compared with healthy controls. The choroidal images on enhanced depth imaging optical coherence tomography (EDI-OCT) were binarized into luminal area (LA) and stromal area (SA) using the ImageJ software. CVI was calculated as the ratio of LA to total choroid area (TCA). The correlations between the results of polysomnography (PSG) and choroidal parameters were evaluated.ResultsA total of 48 eyes of 48 patients (22 patients with OSAS, and 26 controls) were included. The mean age of the patients was 47.21 ± 8.82 (range, 30-63) years. The mean CVI values were 68.10 ± 1.80% in the OSAS group before CPAP therapy, and 69.22 ± 1.40% in the control group (p < 0.05). After 12 months of regular CPAP therapy, the mean CVI value increased significantly to 69.15 ± 1.77%, and SA decreased significantly from 0.51 ± 0.07 mm2 to 0.48 ± 0.07 mm2 in the OSAS group (p < 0.05). No statistically significant correlation was found between the results of PSG and choroidal structural parameters.ConclusionAccording to our results, OSAS was associated with increased stromal oedema in the choroid, which improved after 12 months of regular CPAP therapy. CVI can be an important parameter for the follow-up of patients with OSAS.

Project description:Study aimSevere obstructive sleep apnoea (OSA) can lead to neurocognitive alterations, including gait impairments. The beneficial effects of continuous positive airway pressure (CPAP) on improving excessive daytime sleepiness and daily functioning have been documented. However, a demonstration of CPAP treatment efficacy on gait control is still lacking. This study aims to test the hypothesis that CPAP improves gait control in severe OSA patients.Material and methodsIn this prospective controlled study, twelve severe OSA patients (age = 57.2±8.9 years, body mass index = 27.4±3.1 kg·m-2, apnoea-hypopnoea index = 46.3±11.7 events·h-1) and 10 healthy matched subjects were included. Overground gait parameters were recorded at spontaneous speed and stride time variability, a clinical marker of gait control, was calculated. To assess the role of executive functions in gait and postural control, a dual-task paradigm was applied using a Stroop test as secondary cognitive task. All assessments were performed before and after 8 weeks of CPAP treatment.ResultsBefore CPAP treatment, OSA patients had significantly larger stride time variability (3.1±1.1% vs 2.1±0.5%) and lower cognitive performances under dual task compared to controls. After CPAP treatment, stride time variability was significantly improved and no longer different compared to controls. Cognitive performance under dual task also improved after CPAP treatment.ConclusionEight weeks of CPAP treatment improves gait control of severe OSA patients, suggesting morphological and functional cerebral improvements. Our data provide a rationale for further mechanistic studies and the use of gait as a biomarker of OSA brain consequences.

Project description:ObjectivesRapid eye movement behaviour disorder (RBD) is a parasomnia in which there is loss of muscle atonia during rapid eye movement (REM) sleep, resulting in dream enactment. The aims of this study were to determine the prevalence of obstructive sleep apnoea (OSA) in RBD patients and determine whether continuous positive airway pressure (CPAP) therapy improved RBD symptoms in patients with concomitant RBD and OSA.MethodsA questionnaire was mailed to 120 patients identified from a tertiary sleep centre with RBD meeting full International Classification for Sleep Disorders-3 (ICSD-3) criteria. Patients were diagnosed as having OSA if they had an apnoea-hypopnea index (AHI) ≥ 5. The questionnaire focused on CPAP-use, compliance and complications. Standard statistical analysis was undertaken using SPSS (v.21, IBM).ResultsOne hundred and seven of the potential participants (89.2%) had an OSA diagnosis. Out of 72 who responded to the questionnaire, (60%) 27 patients were using CPAP therapy. CPAP therapy improved RBD symptoms in 45.8% of this group. Despite this positive response to treatment in nearly half of CPAP-users, there was no significant difference in subjective or objective CPAP compliance between those who reported RBD improvement and those who did not. Subjective compliance with CPAP was over-reported, with mean usage being 7.17 ± 1.7 h per night compared to objective mean compliance of 5.71 ± 1.7.ConclusionsOSA is a very common co-morbidity of RBD. CPAP therapy might improve self-reported RBD symptoms further, in addition to standard RBD treatment. However, further research into its topic is necessary.

Project description:IntroductionObstructive sleep apnoea (OSA) is common among older surgical patients, and delirium is a frequent and serious postoperative complication. Emerging evidence suggests that OSA increases the risk for postoperative delirium. We hypothesise that OSA is an independent risk factor for postoperative delirium, and that in patients with OSA, perioperative adherence to positive airway pressure (PAP) therapy decreases the incidence of postoperative delirium and its sequelae. The proposed retrospective cohort analysis study will use existing datasets to: (i) describe and compare the incidence of postoperative delirium in surgical patients based on OSA diagnosis and treatment with PAP; (ii) assess whether preoperatively untreated OSA is independently associated with postoperative delirium; and (iii) explore whether preoperatively untreated OSA is independently associated with worse postoperative quality of life (QoL). The findings of this study will inform on the potential utility and approach of an interventional trial aimed at preventing postoperative delirium in patients with diagnosed and undiagnosed OSA.Methods and analysisObservational data from existing electronic databases will be used, including over 100 000 surgical patients and ~10 000 intensive care unit (ICU) admissions. We will obtain the incidence of postoperative delirium in adults admitted postoperatively to the ICU who underwent structured preoperative assessment, including OSA diagnosis and screening. We will use doubly robust propensity score methods to assess whether untreated OSA independently predicts postoperative delirium. Using similar methodology, we will assess if untreated OSA independently predicts worse postoperative QoL.Ethics and disseminationThis study has been approved by the Human Research Protection Office at Washington University School of Medicine. We will publish the results in a peer-reviewed venue. Because the data are secondary and high risk for reidentification, we will not publicly share the data. Data will be destroyed after 1 year of completion of active Institutional Review Board (IRB) approved projects.

Project description:ContextErectile function is important for life satisfaction and often impaired in men with obstructive sleep apnea (OSA). Uncontrolled studies show that treating OSA with continuous positive airway pressure (CPAP) improves erectile function. Phosphodiesterase type 5 inhibitors (e.g., vardenafil) are the first-line therapy for erectile dysfunction (ED), but may worsen OSA.ObjectiveTo assess the effects of CPAP and vardenafil on ED.DesignSixty-one men with moderate-to-severe OSA and ED were randomized to 12 weeks of CPAP or sham CPAP, and 10 mg daily vardenafil or placebo in a two-by-two factorial design.Main outcome measuresInternational Index of Erectile Function (primary end point), treatment and relationship satisfaction, sleep-related erections, sexual function, endothelial function, arterial stiffness, quality of life, and sleep-disordered breathing.ResultsCPAP increased the frequency of sleep-related erections, overall sexual satisfaction, and arterial stiffness but did not change erectile function or treatment or relationship satisfaction. Vardenafil did not alter erectile function, endothelial function, arterial stiffness, or sleep-disordered breathing, but did improve overall self-esteem and relationship satisfaction, other aspects of sexual function, and treatment satisfaction. Adherent CPAP improved erectile function, sexual desire, overall sexual, self-esteem, relationship, and treatment satisfaction, as well as sleepiness, and quality of life. Adherent vardenafil use did not consistently change nocturnal erection quality.ConclusionCPAP improves overall sexual satisfaction, sleep-related erections, and arterial stiffness. Low-dose daily vardenafil improves certain aspects of sexual function and did not worsen OSA. Adherent CPAP or vardenafil use further improves ED and quality of life.
