Obstructive sleep apnea syndrome is a common disorder with significant health consequences and is on the rise in consonance with the obesity pandemic. In view of the association between sleep-disordered breathing and pulmonary hypertension as depicted by multiple studies, current clinical practice guidelines categorize obstructive sleep apnea as a risk factor for pulmonary hypertension and recommend an assessment for sleep disordered breathing in evaluating patients with pulmonary hypertension. The dysregulatory mechanisms associated with hypoxemic episodes observed in sleep related breathing disorders contribute to the onset of pulmonary hypertension and identification of these potentially treatable factors might help in the reduction of overall cardiovascular mortality.

The aim of research was to estimate the influence of hormone metabolism and sleep apnea on patients with obesity. 76 patients (37 males and 39 females) with obesity were included in this study. After night polysomnography all patients were divided in two groups comparableby age, sex ratio and BMI. The first group consisted of 41 patients with obstructive sleep apnea syndrome (OSAS), the second (controls) – 35 patients without breath disorders during sleep. OSAS is accompanied by the increase in urinary cortisol during the night, high levels ofbasal insulin, disturbances of hepatic production of IGF-1, dysfunction of the pituitary-gonadal axis. Our results show that sleep-related breathing disorders render markedly and negatively affect on hormonal parameters of patients with obesity. As a reliable difference of basalsecretion of orexin A in obese patients with and without OSAS was not revealed (42,0 [14; 99,5] vs. 18,0 [14,5; 124,5] pg/ml; р=0,9), we were not able to show the existence that the existence of OSAS is followed by any special changes of activity of the orexin system.

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.

Upper airway abnormalities increase the risk of pediatric morbidity in infants. A multidisciplinary approach to obstructive sleep apnea syndrome (OSAS) poses challenges to clinical practice. The incidence and causes of OSA are poorly studied in children under 2 years of age. To fill this gap, we performed this retrospective observational study to determine the causes of obstructive sleep apnea (OSA) in children admitted to our hospital between January 2016 and February 2018, after a brief unexplained event (BRUE) or for OSA. We reviewed the medical charts of 82 patients (39 males; BRUE n = 48; OSAS n = 34) and divided them into two age groups: < 1 year old (1–12 months; n = 59) and >1 year old (>12–24 months; n = 23). Assessment included nap polysomnography, multichannel intraluminal impedance-pH, and nasopharyngoscopy. Sleep disordered breathing was comparable between the two groups. Omega-shaped epiglottis, laryngomalacia, and nasal septum deviation were more frequent in the younger group, and nasal congestion in older group. Tonsillar and adenoidal hypertrophy was more frequent in the older group, while laryngomalacia and gastroesophageal reflux was more frequent in the younger group. Tonsil and adenoid size were associated with grade of apnea-hypopnea index severity in the older group, and laryngomalacia and gastroesophageal reflux in the younger group. The main causes of respiratory sleep disorders differ in children before or after age 1 year. Our findings have potential clinical utility for assessing the pathophysiology of obstructive sleep disordered breathing in patients less than 2 years old.

Abstract Introduction Adenotonsillectomy is the first-line treatment for obstructive sleep apnea secondary to adenotonsillar hypertrophy in children. The physical benefits of this surgery are well known as well as its impact on the quality of life (QoL), mainly according to short-term evaluations. However, the long-term effects of this surgery are still unclear. Objective To evaluate the long-term impact of adenotonsillectomy on the QoL of children with sleep-disordered breathing (SDB). Method This was a prospective non-controlled study. Children between 3 and 13 years of age with symptoms of SDB for whom adenotonsillectomy had been indicated were included. Children with comorbities were excluded. Quality of life was evaluated using the obstructive sleep apnea questionnaire (OSA-18), which was completed prior to, 10 days, 6 months, 12 months and, at least, 18 months after the procedure. For statistical analysis, p-values lower than 0.05 were defined as statistically significant. Results A total of 31 patients were enrolled in the study. The average age was 5.2 years, and 16 patients were male. The OSA-18 scores improved after the procedure in all domains, and this result was maintained until the last evaluation, done 22 ± 3 months after the procedure. Improvement in each domain was not superior to achieved in other domains. No correlation was found between tonsil or adenoid size and OSA-18 scores. Conclusion This is the largest prospective study that evaluated the long-term effects of the surgery on the QoL of children with SDB using the OSA-18. Our results show adenotonsillectomy has a positive impact in children's QoL.

Obstructive Sleep

Sleep-related breathing disorders (SBDs) are characterized by abnormal respiration during sleep. Obstructive sleep apnea (OSA), a common SBD increasingly recognized by physicians, is characterized by recurrent episodes of partial or complete closure of the upper airway resulting in disturbed breathing during sleep. OSA syndrome (OSAS) is associated with decreased patients' quality of life (QoL) and the presence of significant comorbidities, such as daytime sleepiness. Similarly to what seen for OSAS, the prevalence of asthma has been steadily rising in recent years. Interestingly, severe asthma (SA) patients are also affected by poor sleep quality—often attributed to nocturnal worsening of their asthma—and increased daytime sleepiness and snoring compared to the general population. The fact that such symptoms are also found in OSAS, and that these two conditions share common risk factors, such as obesity, rhinitis, and gastroesophageal reflux, has led many to postulate an association between these two conditions. Specifically, it has been proposed a bidirectional correlation between SA and OSAS, with a mutual negative effect in term of disease severity. According to this model, OSAS not only acts as an independent risk factor of asthma exacerbations, but its co-existence can also worsen asthma symptoms, and the same is true for asthma with respect to OSAS. In this comprehensive review, we summarize past and present studies on the interrelationship between OSAS and SA, from endo-phenotype to clinical aspects, highlighting possible implications for clinical practice and future research directions.
