As part 3 of the three chapters on sleep-disordered breathing, this chapter reviews central sleep apnea (CSA). CSA is defined as recurrent apneic events during sleep in the absence of respiratory muscle effort and loss of neuronal output to respiratory muscles. The most common cause of CSA is compromised cardiac function. In patients with CSA whose ejection fraction is less than or equal to 45%, adaptive servo-ventilation (ASV) has been shown to increase mortality. With the abuse of opioids reaching epidemic proportions, it has been estimated that 30 to 75% of patients on chronic opioid therapy have a significant increased incidence of CSA. Opioid-induced sleep-disordered breathing can be treated with ASV. This review contains 1 figure, and 37 references. Key Words: adaptive servo-ventilation, central sleep apnea, Cheyne-Stokes respiration, congenital central hypoventilation syndrome, impaired central ventilatory drive, opioid abuse, PHOX2B gene, supplemental oxygen

Disordered Breathing

Sleep-related breathing disorders encompass a wide range of problems that occur during sleep. The most common sleep-related breathing disorder is obstructive sleep apnea syndrome (OSAS). OSAS is increasingly prevalent, underdiagnosed and can lead to significant daytime sleepiness and disability. Continuous positive airway pressure (CPAP) is the treatment of choice for OSAS but lack of adherence to CPAP is rampant. Supportive care, education, and motivational enhancement programs do show promise in improving compliance. Alternatives to CPAP such as oral appliances, hypoglossal nerve stimulation, and myofunctional therapy have not been proved as efficacious but may provide some benefit. In the future, personalized treatment may be the best way to approach this condition. Central sleep apnea and hypoventilation are other forms of sleep-related breathing disorders. Treatment largely depends on the underlying condition but may require the use of advanced modes of noninvasive ventilation such as adaptive servo-ventilation, bilevel positive airway pressure, and volume-assured pressure support. Treatment of sleep-related breathing disorders is complex and includes seeking patient input, understanding barriers to treatment, and reevaluating patients after treatment is initiated. Successful treatment of sleep-disordered breathing can lead to improvements in daytime function, quality of life, and overall health.

Adaptive servo-ventilation (ASV) is a form of non-invasive positive airway pressure (PAP) therapy that differs from other PAP devices. It includes features to overcome both obstructive and central sleep-disordered breathing (SDB) events. In the Treatment of Sleep-Disordered Breathing with Predominant Central Sleep Apnea by Adaptive Servo-Ventilation in Patients with Heart Failure (SERVE-HF) study, ASV significantly reduced SDB events in patients with systolic heart failure (HF) and predominant central sleep apnoea (CSA), but did not improve outcomes, and there was increased mortality risk in the ASV group. Although the SERVE-HF results represent a paradigm shift for ASV, they are only applicable to a small subset of ASV-treated patients, and there is no evidence suggesting that ASV use should stop altogether. There are a number of other indications and patient groups for whom ASV may be useful, effective and safe, including patients with treatment-emergent CSA, central apnoeas associated with long-term opioid therapy without alveolar hypoventilation, idiopathic Cheyne-Stokes respiration, after ischaemic stroke and those with HF with preserved ejection fraction. Additional research is required to better define the mechanism of increased risk associated with ASV identified in SERVE-HF and to more clearly characterise the specific patient phenotypes who benefit from ASV therapy.

Background: Myasthenia Gravis ( MG) is an autoimmune disease that affects the neuromuscular junction. It typically presents with fluctuating muscle weakness which can affect respiratory muscles. Data about the prevalence of sleep disordered breathing in children with MG and the benefits of non-invasive ventilation outside the setting of MG crisis has not been studied so far. Methods: Eleven children between 3 and 18 years old with confirmed MG were recruited from the The Hospital for Sick Children Neuromuscular clinic in a prospective observational study. Informed consent was obtained and patients underwent PFTs, MIP/MEP, SNIP, FVC and standard polysomnography testing’s. Results: In our study, we found that 2/11 children had abnormal Apnea Hypopnea index (AHI) and were diagnosed with obstructive sleep apnea (OSA). One of them has juvenile ocular MG with mild to moderate OSA and the second child has congenital MG with mild OSA. CPAP therapy was initiated for both patients. Conclusions: In our cohort, obstructive sleep apnea rate was significantly higher in children with MG than the known prevalence in general pediatric population ( 18% vs 2-3% ). Early diagnosis and management of OSA can have great impact on children’s health and quality of life. A larger study is needed to validate our findings.

Objective: To systematically review the various modalities of positive airway pressure (PAP) in the treatment of opioid-related central sleep apnea (CSA).Design: Systematic review.Interventions: MEDLINE, the Cochrane Library, and EMBASE were screened through March 2013 to identify articles which investigated treatment of opioid-related CSA with PAP. Eligible articles were identified in a staged process and were assessed by two investigators independently. The methodological quality of the reporting of eligible articles was assessed using a set of questions addressing both general and statistical methodologies.Results: Five articles met the inclusion criteria for a total of 127 patients. All patients had been on opioids for at least 6 months. The dose ranged from 10 mg to 450 mg daily of morphine equivalent dose. Continuous positive airway pressure (CPAP) was proven mostly ineffective in reducing central apneic events. Bilevel positive airway pressure (BiPAP) with and without supplemental oxygen achieved elimination of central apneas in 62 percent of patients. Adaptive servo ventilation (ASV) yielded conflicting results with 58 percent of participants attaining a central apnea index <10 per hour. The presence of ataxic breathing predicted poor response to PAP.Conclusions: The available evidence on the efficacy of PAP in opioid-related CSA is inconclusive. With the increasing use of opioids, further studies are needed to assess optimal PAP therapy and predictors of success in this group of patients.

Introduction: Sleep-disordered breathing is one of the greatest health problems. It comprises of obstructive sleep apnea, central sleep apnea, periodic breathing, and upper airway resistance syndrome. There are several studies reporting association of uncontrolled blood pressurewith individuals having sleep disordered breathing. Data regarding this were sparse in developing countries. Therefore this study was performed to find out the sleep-disordered breathing among uncontrolled hypertensive patients.Materials and Methods: Study was performed from January, 2014 to January, 2017 in sleep center in Kathmandu, Nepal. Patient with uncontrolled BP were included. Uncontrolled BP was defined as blood pressure>130/80mmHg not on intensive antihypertensive regimen and resistant elevated BP was defined as blood pressure >130/80 mmHg despite intensive antihypertensive regimen. These patients were subjected for polysomnography.Results: Three hundred patients were selected out of which 250 patients with uncontrolled blood pressure were included. They were subjected for overnight polysomnography. Among them, 70patients (28%)were found to have mild obstructive sleep apnea, 20 patients had moderate obstructive sleep apnea (8%)&15 had severe obstructive sleep apnea (6%).Conclusions: This study concludes that those individuals having uncontrolled blood pressure has obstructive sleep apnea and these individuals have to undergo polysomnography.Nepalese Medical Journal, vol.1, No. 1, 2018, page: 36-38
