Effects of obstructive sleep apnea and its treatment over the erectile function: a systematic review

Effectiveness of continuous positive airway pressure therapy on romantic relationships and intimacy among individuals with obstructive sleep apnea: A systematic review and a meta-analysis

Obstructive sleep apnea is a common yet often overlooked chronic sleep disorder with significant health implications globally. Bedpartners play a vital role in motivating individuals with obstructive sleep apnea to seek medical help, though their sleep quality may suffer, straining the couple's relationship. From September 2023 to January 2024, utilizing PubMed, Scopus, BioMed Central, Cochrane Library, ScienceDirect and www.clinicaltrials.gov databases, this systematic review meticulously examined data from 27 studies to investigate how continuous positive airway pressure therapy, recognized as the gold-standard for treating obstructive sleep apnea, may positively influence psychological dynamics within couples. Additionally, a meta-analysis was conducted on nine studies, to assess the effect of continuous positive airway pressure on erectile function, which is often compromised in patients with obstructive sleep apnea. The PRISMA checklist and specific quality assessments were followed to ensure methodological rigour and transparency. Findings reveal positive changes in conflict resolution for patients with obstructive sleep apnea post- continuous positive airway pressure adaptation (p < 0.05). Emotional functioning (p = 0.002) and social relationships (p < 0.001) also show improvements in bedpartners. While six subjective assessments indicate enhancements in sexual quality of life for patients with obstructive sleep apnea, challenges related to continuous positive airway pressure use as a barrier to intimacy are acknowledged. Focusing on male patients with obstructive sleep apnea, findings demonstrated a substantial improvement in erectile function post-continuous positive airway pressure utilization, with a Z-score of 4.84 (p < 0.00001). Female patients with obstructive sleep apnea using continuous positive airway pressure show no significant improvements in sexual functioning, while female bedpartners report positive changes. These insights emphasize the importance of holistic approaches in addressing the impact of obstructive sleep apnea on both individuals and their relationships.

A sleep clinician's guide to runny noses: evaluation and management of chronic rhinosinusitis to improve sleep apnea care in adults

STUDY OBJECTIVES

The treatment of obstructive sleep apnea is often impeded by intolerance of positive airway pressure therapy, which is frequently attributed to the inability to breathe through the nose. Providers caring for patients with sleep apnea need a working knowledge of nasal passage disease and available treatments to better manage this common comorbidity.

METHODS

This review examines the literature connecting rhinosinusitis to adverse sleep and sleep apnea outcomes. It explores the different types of nasal and sinus diseases a sleep apnea provider might encounter, focusing on the medications used to treat them and indications for referral to otolaryngology.

RESULTS

Chronic rhinosinusitis can be either allergic or nonallergic. Both types can interfere with sleep and sleep apnea therapy. The successful management of chronic rhinosinusitis can improve positive airway pressure tolerance and adherence. A wide range of over-the-counter and prescription pharmacotherapy is available, with data supporting intranasal over oral treatment. Surgical treatment for chronic rhinosinusitis in obstructive sleep apnea addresses nasal obstruction, often with inferior turbinate reduction and septoplasty.

CONCLUSIONS

Sleep specialists should have a working knowledge of the available options to treat chronic rhinosinusitis. These options are often safe, effective, and readily accessible. Otolaryngologists and allergists/immunologists provide additional treatment options for more complicated patients. Providing treatment for chronic rhinosinusitis should be included as part of comprehensive sleep apnea care.

Bariatric surgery reduces sleep apnea in obese patients with obstructive sleep apnea by increasing pharyngeal cross-sectional area during the early postoperative period

OBJECTIVE

Bariatric surgery (BS) is considered one of the most effective treatments for obese individuals with Obstructive Sleep Apnea (OSA). However, otolaryngologists have raised concerns about the structural alterations caused by BS on the upper respiratory tract, especially, on the pharyngeal cavity.

METHODS

In this study, we recruited 42 individuals who underwent BS at our hospital. They were divided into two groups based on apnea-hypopnea index (AHI): mild group (5 ≤ AHI < 15) and moderate-severe group (AHI ≥ 15). The participants were followed up for 12 months and several indicators, including body mass index (BMI), polysomnography (PSG), and acoustic pharyngometry (APh), were assessed repeatedly before surgery and at 3, 6, and 12 months (m) after surgery.

RESULTS

Participants exhibited significant decreases in BMI (F = 128.1, P = 0.001) and total weight loss (F = 176.7, P < 0.001) after BS. The AHI value among obese patients with mild OSA decreased significantly within three months after surgery (0 day vs. 3 months, P < 0.01), and decreased significantly more than 12 months with moderate-to-severe patients (0 day vs. 3 months, 3 months vs. 6 months, 6 months vs. 12 months, P < 0.01). The therapeutic effect of OSA of the mild group was significantly better compared with that of the moderate-severe group at 6 months (mean rank = 28.13 vs. 14.21, P < 0.001) and 12 m (mean rank = 26.75 vs. 15.52, P = 0.001). The APh results revealed that the pharyngeal volume of the two groups increased significantly between 0 day and 6 months after surgery (P < 0.01). The oropharyngeal junction (OPJ) area and the glottal area were increased significantly between 0 day and 6 m after surgery (P < 0.01).

CONCLUSION

BS can relieve apnea and OSA symptoms among obese patients with OSA, especially in the early postoperative period. Moreover, OSA severity was closely associated with OPJ and glottal areas, rather than pharyngeal cavity volume.

The relationship between sleep disorders, quality, and duration and sexual dysfunction: a systematic review and meta-analysis

BACKGROUND

The associations between sexual dysfunction (SD) and sleep disorders, sleep quality, and sleep duration remain unclear.

AIM

To assess the relationship between sleep and SD through a literature review and meta-analysis.

METHODS

The PubMed, Scopus, Embase, Ovid MEDLINE, and Cochrane Library databases were systematically searched from inception to November 10, 2022.

OUTCOMES

Pooled relative risks and 95% CIs were used to examine the association of sleep disorders with SD in longitudinal studies. Pooled odds ratios (ORs) and 95% CIs were used to examine the associations between SD and sleep disorders, sleep quality, and sleep duration in cross-sectional studies.

RESULTS

Forty-three articles, including 11 longitudinal studies and 32 cross-sectional studies, were included in the quantitative analysis. The pooled relative risk of SD in patients with sleep disorders was 1.97 in longitudinal studies (95% CI, 1.46-2.67, P < .001; heterogeneity: I2 = 95.0%, P < .001), while the pooled OR of SD in patients with sleep disorders was 2.05 in cross-sectional studies (95% CI, 1.76-2.39, P < .001; heterogeneity: I2 = 91.4%, P < .001). When compared with controls, subjects with poor sleep quality had a 1.49-fold increased risk of SD (OR, 1.49; 95% CI, 1.31-1.71, P < .001; heterogeneity: I2 = 73.4%, P < .001). In addition, short sleep duration was associated with the risk of SD (OR, 1.14; 95% CI, 1.06-1.22, P < .001; heterogeneity: I2 = 0.0%, P = .849).

CLINICAL IMPLICATIONS

The risk of SD is significantly increased in patients with sleep disorders and poor sleep quality, indicating that clinicians should monitor sleep among patients with SD.

STRENGTHS AND LIMITATIONS

This study is the most comprehensive meta-analysis of the association between sleep and SD to date. However, different sleep disorders may have varying associations with sleep duration and sleep quality; thus, we could not identify the independent effects across the studies.

CONCLUSION

Our systematic review and meta-analysis results suggest that sleep disorders, especially obstructive sleep apnea, increase the risk of SD in men and women. Poor sleep quality is significantly associated with SD. Short sleep duration is associated with an increased risk of SD.

The Impact of Transoral Robotic Surgery on Erectile Dysfunction and Lower Urinary Tract Symptoms in Male Patients with Moderate-to-Severe Obstructive Sleep Apnea

Obstructive sleep apnea (OSA), lower urinary tract symptoms (LUTS), and erectile dysfunction (ED) are chronic conditions that seriously affect middle-aged men. This study aimed to evaluate the changes in the presence of these conditions after transoral robotic surgery (TORS) for OSA. This prospective observational study recruited 48 men with moderate-to-severe OSA (mean age 40.6 ± 8.1 years) who underwent TORS from October 2019 to November 2021 at a tertiary center. Baseline polysomnographic parameters, Epworth Sleepiness Scale (ESS), and demographic characteristics were measured. The evaluations of LUTS and ED were based on self-administered International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF-5) questionnaires, respectively, before TORS. The treatment outcomes were assessed three months postoperatively in the patients undergoing TORS due to moderate-to-severe OSA. There was significant Apnea-Hypopnea Index (AHI) reduction from 53.10 ± 25.77 to 31.66 ± 20.34 three months after undergoing TORS (p < 0.001). There was also a significant decrease in the total IPSS score (5.06 ± 5.42 at baseline to 2.98 ± 2.71 at three months postoperatively, p = 0.001), the storage domain, and the voiding domain (p < 0.05). The ED also improved significantly, as seen in the IIEF score (20.98 ± 3.32 to 22.17± 3.60, p = 0.007). The reduction of AHI was associated with changes in body weight and the lowest oxygen saturation (SpO2) levels during sleep (rho = 0.395, p = 0.005; rho = 0.526, p < 0.001, respectively). However, the reduction in AHI was not significantly associated with improvement in IPSS or IIEF scores (p > 0.05). For men with moderate-to-severe OSA, TORS can significantly improve the polysomnography parameters, sleep-related questionnaire scores, and quality of life, and alleviate ED and LUTS. AHI reduction is not a crucial factor for ED and LUTS improvement after TORS for OSA, especially in ED.

Impaired Human Sexual and Erectile Function Affecting Semen Quality, in Obstructive Sleep Apnea: A Pilot Study

Obstructive sleep apnea (OSA) is a rising problem, with important implications for public health. Recent evidence has revealed a link between OSA and reduced male fertility. We investigated the association between OSA and sexual and erectile function, as well as semen quality, and the effect of treatment by continuous positive airway pressure (CPAP). A total of 41 male subjects, who underwent polysomnography for suspected OSA, participated in the study. Erectile and sexual function were assessed with the 15-item International Index of Erectile Function (IIEF-15) questionnaire, blood samples, and sperm analysis. OSA patients after the initiation of CPAP treatment were followed for a period of 1 year. Thirty-two patients were diagnosed with OSA, and nine subjects without OSA were used as a control group. OSA patients demonstrated significantly impaired erectile function, reduced testosterone levels, and lower semen quality. Multivariable regression analysis showed that BMI and IIEF score were independent determinants of AHI. Sexual function improved after a year of CPAP therapy in OSA patients. This study provides further evidence regarding the association between OSA and erectile function impairment, as well as semen quality. Longitudinal adherence to CPAP treatment has a beneficial effect on erectile function.

Risk of Infertility in Males with Obstructive Sleep Apnea: A Nationwide, Population-Based, Nested Case‒Control Study

Obstructive sleep apnea (OSA) yields intermittent hypoxia, hypercapnia, and sleep fragmentation. OSA is associated with chronic medical conditions such as cardiovascular diseases, metabolic syndrome, and neurocognitive dysfunction. However, the risk of infertility in OSA remains unclear due to limited data and lack of long-term population-based studies. The study aims to assess the risk of infertility in obstructive sleep apnea (OSA) by means of a population-based cohort study. The data was utilized from the Taiwan National Health Insurance Research Database (NHIRD) to conduct a population-based cohort study (1997–2013). Compared with the Non-OSA group, the male with OSA and surgery group has the OR (odds ratio) of infertility of 2.70 (95% CI, 1.46–4.98, p = 0.0015), but no significance exists in females with OSA. When the data was stratified according to age and gender, some associations in the specific subgroups were significant. Respectively, males aged 20–35 years old and aged 35–50 years old with a history of OSA and surgery both had a positive association with infertility. (aOR: 3.19; 95% CI, 1.18–8.66, p = 0.0227; aOR: 2.57; 95% CI, 1.18–5.62 p = 0.0176). Male patients with OSA suffer from reduced fertility, but no significant difference was noted in females with OSA. The identification of OSA as a risk factor for male infertility will aid clinicians to optimize long-term medical care. Furthermore, more studies will be encouraged to clarify the effect of OSA on female fertility.

Quality of life in upper airway resistance syndrome

STUDY OBJECTIVES

To evaluate the health-related quality of life (HRQoL) in patients with upper airway respiratory syndrome (UARS) and obstructive sleep apnea (OSA) compared to the general population (GP) in Lima, Peru, and to explore the variables associated with differences in HRQoL in patients with UARS.

METHODS

This was a retrospective study of medical and polysomnography records from 2009-2014 in a referral sleep medicine center for patients aged 18-64 years. UARS was defined by polysomnography as follows: apnea-hypopnea index < 5 events/h, oxygen saturation ≥ 92%, respiratory effort-related arousal index ≥ 5. HRQoL was assessed using the 36-Item Short Form Survey (version 1) questionnaire validated in Peru. The GP HRQoL was obtained from a population-based survey. Linear and logistic regression analyses were conducted.

RESULTS

We reviewed 1,329 polysomnograms and selected 888. UARS and OSA were diagnosed in 93 and 795 participants, respectively. The GP cohort consisted of 641 participants. Total HRQoL mean scores (95% confidence interval) in patients with UARS, patients with OSA, and the GP were 67.4 (63.7-71.1), 66.9 (65.4-68.4), and 82.9 (81.6-84.3), respectively. Patients with UARS and patients with OSA had a 5.5 times (95% confidence interval, 3.3-9.2) and 6.2 times (95% confidence interval, 4.6-8.4) greater probability of having a low total HRQoL score compared to patients in the GP, respectively. In patients with UARS, muscle pain, use of psychotropic medication, obesity, and depression were negatively correlated with the total HRQoL score.

CONCLUSIONS

The impact of OSA and UARS on HRQoL is similar between disease groups and markedly worse when compared to the impact in the GP. In patients with UARS, the presence of muscle pain, obesity, female sex, depression, and use of psychotropic medication negatively impacted HRQoL.

Combined application of pharyngeal volume and minimal cross-sectional area may be helpful in screening persons suspected of obstructive sleep apnea (OSA)

BACKGROUND

Obstructive sleep apnea (OSA) is a common disease that seriously affects human health and daily life. However, the gold standard for its diagnosis, polysomnography (PSG), is expensive resulting in inadequate diagnosis of this disease in primary clinics. Therefore, a simple and rapid method for initial screening for OSA is needed. Acoustic pharyngometry (APh) is an FDA-approved noninvasive method that is gradually being applied to screening for OSA.

MATERIALS AND METHODS

In this study, we applied analysis with receiver operating characteristic (ROC) curves to explore how APh may play a greater role in the screening of subjects with suspected OSA. Patients admitted into the departments of otolaryngology at our hospital from March 2017 to May 2019 were recruited into the study. All subjects underwent PSG monitor and were separated into two groups according to the apnea-hypopnea index (AHI) from the PSG results: OSA group (AHI ≥ 5) and control group (AHI < 5). APh measurements and other indicators of the subjects, including age, height, and weight; Epworth Sleepiness Scale (ESS) score; and the pharynx examination, including the degree of tonsil enlargement and tongue hypertrophy, were also be recorded.

RESULTS

The t-test results showed that almost all indicators except age and height have significant differences between the OSA group and control group. Subjects with OSA had greater weight, BMI, ESS, higher degree of tonsil enlargement, and tongue hypertrophy, while they had smaller minimal cross-sectional area (mCSA) and pharyngeal volume than the subjects in control group. The correlation analysis revealed that pharyngeal volume and mCSA were two helpful indicators to screen for OSA. Furthermore, we established the ROC curve and calculated the combining predictors (combining predictors = pharyngeal volume + mCSA * (- 2.347)/(- 0.225)). The area under the ROC curve (AUC) of combining predictors was 0.917 (95% CI 0.842-0.991, P < 0.001), which was higher than combinations of other two independent indicators. The cutoff point of combining predictors was found to be 59.84 (AUC = 0.917, sensitivity = 0.80, 1-specificity = 0.06, P < 0.001).

CONCLUSIONS

These findings suggest that APh is a simple, rapid, and economical detection method which may be useful in screening for OSA, especially in communities and primary clinics where PSG cannot be performed.

Erectile Dysfunction and Obstructive Sleep Apnea: A Review

Erectile dysfunction (ED) is a disease with a wide scope of etiologies. Obstructive sleep apnea (OSA) is considered one of the risk factors for ED and is less studied. A growing lot of evidence show an association between OSA and ED. This study provides an updated review of the relationship between ED and OSA and the possible physiological mechanisms of ED in patients with OSA based on the current evidence. In clinical interviews, patients with ED may benefit from a sleep evaluation. However, further clinical investigations and more basic research are needed to illustrate the relationship between ED and OSA.

Surgical treatments for obstructive sleep apnea decrease the risk of erectile dysfunction: A nationwide cohort study

BACKGROUND

It has been reported that the risk of erectile dysfunction (ED) is significantly higher in patients with obstructive sleep apnea (OSA), compared with patients without OSA. However, there is limited evidence on whether surgical treatments in patients with OSA could decrease ED risk.

OBJECTIVES

To assess the impact of surgical treatments for OSA on the risk of ED by analysis of claims data from the Taiwan National Health Insurance Research Database between 1997 and 2012.

MATERIAL AND METHODS

We identified 20,675 male adults with newly diagnosed OSA during the study period; 16,040 patients ever received surgical treatments (treated cohort) and 4635 patients never received surgical treatments (untreated cohort). According to 3:1 propensity score matching, we analyzed 8337 patients in the treated cohort and 2779 controls in the untreated cohort. We estimated the incidence rates (IRs) and hazard ratios (HRs) of incident ED in both cohorts through the end of 2012.

RESULTS

In a total study follow-up of 64,916 person-years, 396 (3.6%) patients developed impotence. The IRs of ED for the treated and untreated cohorts, respectively, were 55.8 (95% confidence interval [CI], 55.6-55.9) and 76.1 (95% CI, 76.0-76.3) per 1000 person-years. Multivariate Cox proportional hazard analysis showed that surgical treatments for OSA patients were associated with a lower risk for ED (adjusted HR, 0.79; 95% CI, 0.64-0.98). Multivariate stratified analysis further verified that significant risk reduction of ED was present in OSA patients without hypertension, diabetes, hyperlipidemia, hyperuricemia, obesity, chronic kidney disease, and chronic liver disease.

CONCLUSIONS

We found that OSA patients who received surgical treatments were associated with a lower risk for developing ED by 21%.

Update of the position paper on arterial hypertension and erectile dysfunction

: Sexual health is an integral part of overall health, and an active and healthy sexual life is an essential aspect of a good life quality. Cardiovascular disease and sexual health share common risk factors (arterial hypertension, diabetes mellitus, dyslipidemia, obesity, and smoking) and common mediating mechanisms (endothelial dysfunction, subclinical inflammation, and atherosclerosis). This generated a shift of thinking about the pathophysiology and subsequently the management of sexual dysfunction. The introduction of phosphodiesterase type 5 inhibitors revolutionized the management of sexual dysfunction in men. This article will focus on erectile dysfunction and its association with arterial hypertension. This update of the position paper was created by the Working Group on Sexual Dysfunction and Arterial Hypertension of the European Society of Hypertension. This working group has been very active during the last years in promoting the familiarization of hypertension specialists and related physicians with erectile dysfunction, through numerous lectures in national and international meetings, a position paper, newsletters, guidelines, and a book specifically addressing erectile dysfunction in hypertensive patients. It was noted that erectile dysfunction precedes the development of coronary artery disease. The artery size hypothesis has been proposed as a potential explanation for this observation. This hypothesis seeks to explain the differing manifestation of the same vascular condition, based on the size of the vessels. Clinical presentations of the atherosclerotic and/or endothelium disease in the penile arteries might precede the corresponding manifestations from larger arteries. Treated hypertensive patients are more likely to have sexual dysfunction compared with untreated ones, suggesting a detrimental role of antihypertensive treatment on erectile function. The occurrence of erectile dysfunction seems to be related to undesirable effects of antihypertensive drugs on the penile tissue. Available information points toward divergent effects of antihypertensive drugs on erectile function, with diuretics and beta-blockers possessing the worst profile and angiotensin receptor blockers and nebivolol the best profile.

Identifying Signs and Symptoms of Obstructive Sleep Apnea in a Men's Health Clinic: The Utility of Home Sleep Apnea Testing During COVID-19

The objective of the study was to identify symptoms of men presenting for an outpatient urology visit that prompted referral for a Home Sleep Apnea Test (HSAT) to assess for obstructive sleep apnea (OSA) by a single provider. To assess the proportion of patients referred for the HSAT who underwent the test and, out of these patients, the proportion of men diagnosed with sleep apnea, we performed a retrospective chart review of men 18-99 years old seen by a single provider in the Department of Urology referred for an HSAT to evaluate for presenting symptoms. Patients with a prior diagnosis of OSA were excluded. Eighteen patients were identified (mean age at time of referral 51 + SD 13 years). Half of patients reported erectile dysfunction/concerns, 56% reported nocturia, 44% had been diagnosed with testosterone deficiency, and 39% reported low libido. Nearly all (89%) of patients snored, all reported fatigue, 56% were over the age of 50, 44% had a BMI >35, and 78% had hypertension. Twelve patients completed the HSAT, all of whom were diagnosed with OSA for which continuous positive airway pressure (CPAP) therapy was initiated. Men presenting with genitourinary concerns to an outpatient urology clinic may also have OSA. About half of included patients reported genitourinary concerns. Hundred percent of patients who completed their sleep study were diagnosed with OSA. Genitourinary concerns, in addition to signs and symptoms commonly associated with OSA, should prompt consideration of sleep apnea evaluation.

Valproate, sexual health, and men: A narrative review

OBJECTIVE

This article explores current evidence about the effects of valproate (VPA) medicines on sexual health in men, how to monitor symptoms, communicate with patients, and improve clinical outcomes. There has been a lot of focus on VPA use in women of childbearing age following recent changes to prescribing regulations owing to the well-established and significant teratogenic risk. Concerns have been raised by patients and clinicians as to the risk of adverse sexual effects of VPA use in men.

RESULTS

The evidence base for the effect of VPA on sexual function compared with other antiepileptic drugs (AEDs) in men is limited with no randomized controlled trials. Sexual function in men with epilepsy is complex, and there is no direct relationship between objective measures of sexual function and sexual satisfaction. Epilepsy, comorbidities, psychosocial factors, and most AEDs including VPA may cause sexual dysfunction in men, including reduced sexual desire, erectile dysfunction, and fertility problems. Sexual and reproductive function should be discussed with men prior to treatment with AEDs including VPA.

CONCLUSION

Early and proactive discussion of sexual and reproductive functioning mitigates, rather than increases, the risk of sexual problems and potentially improves adherence. Sexual dysfunction in men with cognitive impairment [such as intellectual disability (ID) and dementia] may present with behavioral disturbance. Identification of sexual adverse effects of medication could significantly change treatment plans which is of particular importance for individuals with treatment resistance. We provide an information fact sheet for men to help guide prescribing discussions.

Blood Oxygen Accumulation Distribution Area Index Is Associated With Erectile Dysfunction in Patients With Sleep Apnea-Results From a Cross-sectional Study

Introduction

Obstructive sleep apnea (OSA) has been linked with erectile dysfunction (ED), but the relatively independent polysomnography (PSG) outcomes of apnea and nocturnal hypoxia may not effectively assess the physiological impairment of OSA well.

Aim

To propose a new calculation method, the blood oxygen accumulation distribution area index (BOADAI), for evaluating the association between OSA and ED.

Methods

In this study, 502 male participants with suspected OSA were enrolled. Clinical questionnaire, physical measurements, and PSG outcomes were obtained by 2 respiratory physicians. ED was assessed by a urologist using the International Index of Erectile Function-5 (IIEF-5). Whole pulse oxygen saturation curves during the sleep time were compressed into a fixed scale image, and the distribution area of oxygen saturation curves was outlined. We then calculated the value of the outlined area and normalized it by total sleep time. The least absolute shrinkage and selection operator logistic regression model was used for selecting the optimal variable associated with ED and model construction. The clinical net benefit of the BOADAI and its related modules was estimated and compared by decision curve analysis.

Main Outcome Measure

ED and OSA were assessed using the IIEF-5, clinical questionnaire, physical measurements, and PSG outcomes.

Results

The frequency of ED in patients with OSA was significantly greater than that in the no-OSA group. Meanwhile, the new BOADAI was negatively correlated with the IIEF-5 score (r = −0.2525, P = .0000). Moreover, the least absolute shrinkage and selection operator method retained BOADAI but not the other PSG parameters such as respiratory disorder index and lowest SaO2. Finally, logistic regression analysis revealed that older age, lips with cyanochroia, systemic hypertension, and BOADAI were independently associated with ED, and decision curve analysis indicated the clinical usefulness of the BOADAI module.

Conclusion

This study revealed novel evidence that OSA is a risk factor for ED. Meanwhile, the BOADAI could act as a potential clinical characteristic to evaluate ED in patients with OSA and to provide clinical treatment recommendations.

May Dyspnea Sensation Influence the Sexual Function in Men With Obstructive Sleep Apnea Syndrome? A Prospective Control Study

INTRODUCTION

Dyspnea sensation is frequently present in obstructive sleep apnea syndrome (OSA) patients; however, its possible influence on sexual function and body image has not been well analyzed.

AIMS

To evaluate sexual function, the prevalence of sexual dysfunction (SD), and body image during sexual activity and its relationship with dyspnea in men with OSA.

METHODS

129 men were included in the prospective study, with 61 diagnosed with OSA (cases) and 68 age- and BMI-matched healthy control subjects. Patients were assessed for the severity of heart failure by the New York Heart Association scale and dyspnea by the Visual Analogue Scale. OSA was confirmed by in-laboratory polysomnography.

MAIN OUTCOME MEASURES

International Index of Erectile Function (IIEF) was used as a measure of sexual function, body image during sexual activity was assessed by the Body Exposure During Sexual Activity Questionnaire, whereas SD was diagnosed using criteria from the Diagnostic and Statistical Manual of Mental Disorders, 5th edition.

RESULTS

The mean age of the studied population was 57.9 ± 10.8 years. Presence of dyspnea interfered with sexual life in 20% of men diagnosed with OSA and with work performance in 33%. Men with OSA had worse scores in IIEF-15 compared with control subjects and higher frequency of sexual distress compared with men with OSA. There were no differences in the rate of SD according to criteria from the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition. The presence of OSA worsened the perceived body image during sexual activity. The presence of dyspnea was the only negative factor affecting sexual function in general (IIEF-15 score) and 1 of the factors affecting erectile function and orgasmic function.

CONCLUSION

In men with OSA, body image is negatively influenced by the presence of OSA. Furthermore, the presence of dyspnea assessed by the New York Heart Association scale impairs sexual function in that group of men. Skoczyński S, Nowosielski K, Minarowski Ł, et al.

Obstructive sleep apnea: personal, societal, public health, and legal implications

Introduction Obstructive sleep apnea (OSA) is a widely prevalent sleep-related breathing disorder, which leads to several life-threatening diseases. OSA has systemic effects on various organ systems. Untreated OSA is associated with long-term health consequences including hypertension, heart disease, diabetes, depression, metabolic disorders, and stroke. In addition, untreated OSA is reported to be associated with cognitive dysfunction, impaired productivity at the workplace and in an increased risk of motor vehicle accidents (MVAs) resulting in injury and fatality. Other consequences of OSA include, but are not limited to, impaired vigilance, daytime somnolence, performance deficits, morning headaches, mood disturbances, neurobehavioral impairments, and general malaise. Additionally, OSA has become an economic burden on most health systems all over the world. Many driving license regulations have been developed to reduce MVAs among OSA patients. Methods Studies of the personal, societal, public health, and legal aspects of OSA are reviewed. Data were collected through the following databases: MEDLINE, Google Scholar, Scopus, SAGE Research Methods, and ScienceDirect. Conclusion OSA leads to worsening of patients' personal relationships, decreasing work productivity, and increasing occupational accidents as well as MVAs. The costs of undiagnosed and untreated OSA to healthcare organizations are excessive. Thus, proper management of OSA will benefit not only the patient but will also provide widespread benefits to the society as a whole.

Holistic Management of Obstructive Sleep Apnea: Translating Academic Research to Patient Care

A holistic approach is pertinent in managing obstructive sleep apnea (OSA). It goes beyond integrated multidisciplinary assessment and management in the hospital setting. Although clinicians should be aware of different treatment modalities and adjunctive measures, proactive management of OSA is as important. The future of OSA management lies in identifying patients at risk of developing OSA and developing strategy to prevent OSA from taking root. It involves active screening of patients with OSA and treating them and identifying patients with OSA with high risk of preventable serious morbidity and death and intervening early to prevent these from happening.

Obstructive Sleep Apnea and Inflammation: Proof of Concept Based on Two Illustrative Cytokines

Obstructive sleep apnea syndrome (OSAS) is a markedly prevalent condition across the lifespan, particularly in overweight and obese individuals, which has been associated with an independent risk for neurocognitive, behavioral, and mood problems as well as cardiovascular and metabolic morbidities, ultimately fostering increases in overall mortality rates. In adult patients, excessive daytime sleepiness (EDS) is the most frequent symptom leading to clinical referral for evaluation and treatment, but classic EDS features are less likely to be reported in children, particularly among those with normal body-mass index. The cumulative evidence collected over the last two decades supports a conceptual framework, whereby sleep-disordered breathing in general and more particularly OSAS should be viewed as low-grade chronic inflammatory diseases. Accordingly, it is assumed that a proportion of the morbid phenotypic signature in OSAS is causally explained by underlying inflammatory processes inducing end-organ dysfunction. Here, the published links between OSAS and systemic inflammation will be critically reviewed, with special focus on the pro-inflammatory cytokines tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6), since these constitute classical prototypes of the large spectrum of inflammatory molecules that have been explored in OSAS patients.

Erectile dysfunction in obstructive sleep apnea patients: A randomized trial on the effects of Continuous Positive Airway Pressure (CPAP)

OBJECTIVES

Obstructive 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.

METHODS

Cross-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.

RESULTS

ED 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.

CONCLUSIONS

This 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.

Association of Continuous Positive Airway Pressure Treatment With Sexual Quality of Life in Patients With Sleep Apnea: Follow-up Study of a Randomized Clinical Trial

Importance

Obstructive sleep apnea reduces sexual quality of life (QOL) as a result of reduced libido and intimacy, erectile dysfunction, and several other mechanisms. Treatment for obstructive sleep apnea may improve sexual QOL.

Objective

To test the association of long-term continuous positive airway pressure (CPAP) treatment with sexual QOL for patients with obstructive sleep apnea.

Design, Setting, and Participants

Prospective cohort study at a single, tertiary medical center of patients with newly diagnosed obstructive sleep apnea who were prescribed CPAP treatment from September 1, 2007, through June 30, 2010 (follow-up completed June 30, 2011). The statistical analysis was performed from February 1 through December 31, 2017.

Exposures

Use of CPAP treatment objectively measured by the number of hours per night. Users of CPAP were defined as patients who used CPAP treatment for more than 4 hours per night, and nonusers were defined as patients who used CPAP treatment for fewer than 0.5 hours per night.

Main Outcomes and Measures

Data were collected from eligible patients before CPAP treatment was prescribed and 12 months later by using the validated Symptoms of Nocturnal Obstruction and Related Events-25 (SNORE-25) QOL instrument. The 2 sex-specific items used to create the sexual QOL domain were taken from the SNORE-25. The sexual QOL domain was scored in a range from 0 to 5 (higher score is worse). The difference in sexual QOL between CPAP users and nonusers was analyzed using a paired, 2-tailed t test and multivariable linear regression adjusted for potential confounders.

Results

Of the 182 participants in the cohort, 115 (63.2%) were men (mean [SD] age, 47.2 [12.3] years) with severe OSA (mean [SD] apnea-hypopnea index, 32.5 [23.8] events per hour). At the 12-month follow-up, 72 CPAP users (mean [SD] use, 6.4 [1.2] hours per night) had greater improvement than 110 nonusers (0 [0] hours per night) in sexual QOL scores (0.7 [1.2] vs 0.1 [1.1]; difference, 0.54; 95% CI, 0.18-0.90; effect size, 0.47). A moderate treatment association was observed after adjustment for age, sex, race/ethnicity, marital status, income level, educational level, body mass index, apnea-hypopnea index, and the Functional Comorbidity Index (adjusted difference, 0.49; 95% CI, 0.09-0.89; effect size, 0.43). Subgroup analysis revealed a large treatment association for women (adjusted difference, 1.34; 95% CI, 0.50-2.18; effect size, 0.87) but not for men (adjusted difference, 0.16; 95% CI, -0.26 to 0.58; effect size, 0.19).

Conclusions and Relevance

Successful CPAP use may be associated with improved sexual QOL. Subgroup analysis revealed a large improvement in women but no improvement in men. Further study is warranted to test other measures of sexual QOL and other treatments.

Sleep disorders in patients with erectile dysfunction

OBJECTIVE

To assess the prevalence of obstructive sleep apnoea (OSA) in men presenting with erectile dysfunction (ED) at a single centre.

PATIENTS AND METHODS

All men attending a specialised andrology outpatient department with a new diagnosis of ED were included in this prospective study. All patients completed three questionnaires: the International Index of Erectile Function (IIEF) and two sleep questionnaires [the Obstructive Sleep Apnoea Screening questionnaire and the Insomnia Severity Index (ISI)]. Their ED management was subsequently undertaken in accordance with local and European guidelines. An OSA diagnosis was made based on a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire and those patients were referred for specialist management.

RESULTS

Between February and September 2016, 129 patients with ED completed the study questionnaires. In all, 71 patients (55%) had a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire, indicating a need for specialist sleep referral. Men who scored ≥3 on the Obstructive Sleep Apnoea Screening questionnaire were significantly older (61.4 vs 46.5 years; P < 0.001) and had a significantly higher body mass index (29.4 vs 26.7 kg/m² ; P < 0.001) when compared to the control group (OSA score of <3). The sleep apnoea group (OSA score of ≥3) had significantly worse IIEF-ED scores (6.2 vs 9.1; P = 0.018) and ISI scores (7.9 vs 5.5; P = 0.061).

CONCLUSION

Men presenting to the andrology clinic with ED are at significant risk of having undiagnosed sleep disorders. This has serious adverse health consequences, as well as being associated with potential dangers at work and travel. The patient compliance was high with 78% completing all three questionnaires. It is feasible to screen this population for sleep disturbance and this should be part of the ED assessment.
