Complex sleep apnea syndrome

Dongmei Lu, Nanfang Li, Xiaoguang Yao, Ling Zhou
Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a complex chronic inflammatory respiratory disease with multiple pathogenic factors and high morbidity and mortality. Serum levels of nuclear factor-κB (NF-κB), hypoxia-inducible factor-1 alpha (HIF-1α), and surfactant protein D (SPD) were investigated in OSAHS patients, to determine their clinical significance and correlation with the pathogenesis. Patients were classified into a mild and moderate OSAHS group (n = 25) and severe OSAHS group (n = 33). Twenty healthy patients served as a control group...

Obstructive sleep apnea syndrome (OSAS) is the most common type of sleep disorder which is associated with a series of cardiovascular disorders, including right ventricular (RV) dysfunction. However, it is difficult to assess the RV function systematically using a conventional echocardiography because RV has a complex geometrical shape. A case-control study was performed to assess the regional right ventricular potential dysfunction in patients with OSAS using velocity vector imaging (VVI) from March 2014 to October 2015...

OBJECTIVE: This study aimed to determine association obstructive sleep apnea (OSA) with increased coagulability and reveal possible effects of constant positive airway pressure (CPAP). DESIGN AND METHOD: We included 77 patients with arterial hypertension (duration of AH = 13.8 ± 3.7 years), middle-aged (45.9 ± 10.5 years). 41 (53.2%) of them had severe OSA (AHI = 59.6 ± 26). OSA was diagnosed by means of cardiorespiratory monitoring. In patients with severe OSA blood samples (D-dimer, viscosity of blood, erythrocyte aggregation) were taken at baseline and after 3-4 nights of effective CPAP therapy (AHI < 5)...

Zolpidem-induced sleep-related complex behaviors (SRCB) with anterograde amnesia have been reported. We describe herein a case in which the development of zolpidem-induced sleep-related eating disorder (SRED) and SRCB was strongly suspected. A 71-year-old Korean male was admitted to the Department of Psychiatry due to his repetitive SRED and SRCB with anterograde amnesia, which he reported as having occurred since taking zolpidem. The patient also had restless legs syndrome (RLS) and obstructive sleep apnea (OSA)...

PURPOSE: Quantitative image analysis in previous research in obstructive sleep apnea syndrome (OSAS) has focused on the upper airway or several objects in its immediate vicinity and measures of object size. In this paper, we take a more general approach of considering all major objects in the upper airway region and measures pertaining to their individual morphological properties, their tissue characteristics revealed by image intensities, and the 3D architecture of the object assembly...

Endothelin-1, (ET-1, EDN1) is endogenous polypeptide demonstrates dominant vasoconstriction activity and mitogenic effect, on the heart it has positive inotropic and chronotropic properties, stimulates the sympathetic and the renin-angiotensin-aldosterone systems and modify homeostasis. The human ET-1 gene which consists of 6836 nucleotides located on chromosome 6p23-p24 produces Pre-pro-ET-1, which consequently cleaved to big-ET-1. The mature 21-amino acid ET-1 is generated by subsequent enzymatic cleavage of the big-ET-1...

INTRODUCTION: Obstructive sleep apnea (OSA) is a secondary cause of intracranial hypertension (IH). Decreased jugular venous drainage has been seen in patients with idiopathic IH. CLINICAL PRESENTATION: A complex case of a 48-year-old female whose idiopathic IH was put into remission after counterclockwise maxillomandibular advancement (CC-MMA), despite persistence of her OSA. CONCLUSION: This case highlights the relationship between OSA and IH and points to the significant morbidity that can result from mild OSA and from what are considered borderline intracranial pressures...

BACKGROUND: Physical activity programs are a powerful tool against several diseases including obesity and their comorbidities. Prader-Willi syndrome is the most common genetic disease associated with obesity, and brings with it behavioral and emotional problems that need complex management. Research into the effect of physical activity programs on Prader-Willi syndrome is limited and it is frequently argued that if a physical activity program is too complex, the participants are more likely to drop out...

Obstructive sleep apnea syndrome (OSAS) is a sleep-related breathing disorder characterized by repetitive episodes of airflow cessation, resulting in brief arousals and intermittent hypoxemia. OSAS is associated with a number of adverse health consequences, and cognitive difficulties. The overall pattern of cognitive impairment in OSAS is complex, and research in this field is mixed. On balance, OSAS have negative effects on cognition, most likely in the domain of attention/vigilance, verbal and visual delayed long-term memory, and executive functions...

Alzheimer's disease (AD) is a leading cause of death and disability among older adults. Modifiable vascular risk factors for AD (VRF) include obesity, hypertension, type 2 diabetes mellitus, sleep apnea, and metabolic syndrome. Here, interactions between cerebrovascular function and development of AD are reviewed, as are interventions to improve cerebral blood flow and reduce VRF. Atherosclerosis and small vessel cerebral disease impair metabolic regulation of cerebral blood flow and, along with microvascular rarefaction and altered trans-capillary exchange, create conditions favoring AD development...

Sleep disorders have a profound and well-documented impact on overall health and quality of life in the general population. In patients with chronic disease, sleep disorders are more prevalent, with an additional morbidity and mortality burden. The complex and dynamic relationship between sleep disorders and chronic kidney disease (CKD) remain relatively little investigated. This article presents an overview of sleep disorders in patients with CKD, with emphasis on relevant pathophysiologic underpinnings and clinical presentations...

A number of autoantibodies, some paraneoplastic, are associated with sleep disorders. Morvan syndrome and limbic encephalitis, associated with voltage-gated potassium channel-complex antibodies, principally against CASPR2 and LGI1, can result in profound insomnia and rapid eye movement sleep behavior disorder (RBD). Patients with aquaporin-4 antibodies and neuromyelitis optica may develop narcolepsy in association with other evidence of hypothalamic dysfunction, sometimes as the initial presentation. Central sleep apnea and central neurogenic hypoventilation are found in patients with anti-N-methyl-d-aspartate receptor antibody encephalitis, and obstructive sleep apnea, stridor, and hypoventilation are prominent features of a novel tauopathy associated with IgLON5 antibodies...

A disease trait often can be characterized by multiple phenotypic measurements that can provide complementary information on disease etiology, physiology, or clinical manifestations. Given that multiple phenotypes may be correlated and reflect common underlying genetic mechanisms, the use of multivariate analysis of multiple traits may improve statistical power to detect genes and variants underlying complex traits. The literature, however, has been unclear as to the optimal approach for analyzing multiple correlated traits...

In infants with craniofacial disorders, upper airway obstruction is one of the primary causes for morbidity and mortality in the neonatal period. Infants with craniofacial disorders, including Pierre Robin sequence, are at high risk for obstructive sleep apnea syndrome. Because of the complexity of their care, these neonates are usually followed by a multidisciplinary team to ensure timely evaluation and optimal treatment. In addition to history and physical examination, clinical evaluation may include genetic testing, imaging, endoscopy, and polysomnography...

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) is accompanied by tissue injury to the insular cortices, areas that regulate autonomic pain, dyspnea, and mood, all of which are affected in the syndrome. Presumably, the dysregulation of insular-related functions are mediated by aberrant functional connections with other brain regions; however, the integrity of the functional connectivity (FC) to other sites is undescribed. Our aim was to examine resting-state FC of the insular cortices to other brain areas in OSA, relative to control subjects...

The obstruction of OSAHS patient is not limited to a single level. These blockages of multiple sites trend to influence each other and participate in a complex process. To date, the determination of obstruction is often depends on empirical judgment of clinician. However, it is a key issue to find out which level of obstruction is most significant. The article will focus on the commonly used values in laboratory examinations and their relationship with AHI. Based on the existing work, we decide to make a comprehensive analysis of their predictive value...

BACKGROUND: OSA is a highly prevalent condition that is associated with a wide range of long-term morbidities including metabolic, cardiovascular, and cognitive alterations, possibly via activation of systemic inflammatory and oxidative stress pathways. Implementation of positive airway pressure (PAP) is the first-line treatment for OSA, as well as for obesity hypoventilation syndrome (OHS), its most severe phenotype. However, the molecular and cellular mechanisms underlying OHS-induced morbidities and their response to PAP treatment remain unclear, and could be mediated, in part, by OSA-induced epigenetic changes...

Complex regional pain syndrome (CRPS) is evoked by conditions that may be associated with local and/or systemic inflammation. We present a case of long-standing CRPS in a patient with Ehlers-Danlos syndrome in which prolonged remission was attained by directing therapy toward concomitant small intestinal bacterial overgrowth, obstructive sleep apnea, and potential increased microglia activity. We theorize that cytokine production produced by small intestinal bacterial overgrowth and obstructive sleep apnea may act as stimuli for ongoing CRPS symptoms...

A 75-year-old man complained of excessive daytime sleepiness (EDS), difficulty falling asleep and nocturnal agitation during sleep. Restless legs syndrome (RLS) was diagnosed and treated. Because of persistent EDS, snoring and nycturia, a nocturnal polysomnography (PSG) was performed. PSG showed high sleep fragmentation related to a moderate to severe obstructive sleep apnea syndrome. Continuous positive airway pressure treatment (CPAP) was proposed. Because of the persistence of abnormal nocturnal behaviours, characterized by screaming, punching and falling out of bed, a video-PSG with CPAP treatment was performed...
