Sleep Breath 2024; 28:251-260. [PMID: 37563524 DOI: 10.1007/s11325-023-02900-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 07/28/2023] [Accepted: 08/04/2023] [Indexed: 08/12/2023]
Abstract
PURPOSE Children with Down Syndrome (DS) have a high prevalence of obstructive sleep apnea (OSA). We aimed to assess OSA prevalence in a single center cohort of children with DS, identify associated risk factors of obstructive respiratory events, and examine the influence of different sleep stages and body positions on respiratory events distribution. METHODS Single center retrospective study that included children with DS who underwent overnight polysomnogram (PSG). OSA severity was categorized by obstructive apnea-hypopnea index (OAHI) as mild (1.5-4.9 events/h), moderate (5-9.9 events/h), and severe (≥ 10 events/h). A logistic regression analysis was used to examine the association between OSA-related risk factors in normal and abnormal OAHI category and in REM and Non-REM predominant AHI groups. RESULTS PSG data were available for 192 children with a median age of 5 years (IQR 7). OSA prevalence was 82.3% (27.1% mild, 19.8% moderate, and 35.4% severe). A logistic regression model identified BMI and being an African American as significant predictors for OAHI severity. In children with OSA, the median OAHI was 7.6 and obstructive respiratory events were more common in REM sleep and in the supine position. The median REM OAHI was 20 events/h (IQR: 24.4), whereas the median Non-REM OAHI was 5.2 events/h (IQR: 12.6 p < 0.0001). Similarly, supine OAHI was 11.6 (IQR: 19.3) and off supine OAHI was 6.6 (IQR: 11.6, p = 0.0004). Age was a significant predictor (p = 0.012) for Non-REM predominant OSA which was present in 15.2% of children with OSA. CONCLUSION Children with DS have a high prevalence of OSA. Higher BMI and being an African American were significant associated risk factors for higher OAHI. Obstructive respiratory events in children with DS occur predominantly in REM sleep and in the supine position. Non-REM predominant distribution of respiratory events was noted in older children with DS.

Abstract
STUDY OBJECTIVES To examine children with Down syndrome with residual obstructive sleep apnea (OSA) to determine if they are more likely to have positional OSA. METHODS A retrospective chart review of children with Down syndrome who underwent adenotonsillectomy at a single tertiary children's hospital was conducted. Children with Down syndrome who had a postoperative polysomnogram with obstructive apnea-hypopnea index (OAHI) > 1 event/h, following adenotonsillectomy with at least 60 minutes of total sleep time were included. Patients were categorized as mixed sleep (presence of ≥ 30 minutes of both nonsupine and supine sleep), nonsupine sleep, and supine sleep. Positional OSA was defined as an overall OAHI > 1 event/h and a supine OAHI to nonsupine OAHI ratio of ≥ 2. Group differences are tested via Kruskal-Wallis test for continuous variables and Fisher's exact tests for categorical. RESULTS There were 165 children with Down syndrome who met inclusion criteria, of which 130 individuals had mixed sleep. Patients who predominately slept supine had a greater OAHI than mixed and nonsupine sleep (P = .002). Sixty (46%) of the mixed-sleep individuals had positional OSA, of which 29 (48%) had moderate/severe OSA. Sleeping off their backs converted 14 (48%) of these 29 children from moderate/severe OSA to mild OSA. CONCLUSIONS Sleep physicians and otolaryngologists should be cognizant that the OAHI may be an underestimate if it does not include supine sleep. Positional therapy is a potential treatment option for children with residual OSA following adenotonsillectomy and warrants further investigation. CITATION Lackey TG, Tholen K, Pickett K, Friedman N.

Abstract
Sleep is a major concern, especially in people with Down Syndrome (DS). Beyond Obstructive Sleep Apnea, a number of other sleep difficulties have been reported in children with DS, such as delayed sleep onset, night-time awakenings, and early morning awakenings. The detrimental effect of sleep difficulties seems to contribute to and exacerbate the cognitive and behavioral outcomes of DS. Although the screening for sleep disorders is recommended early in age in DS, only a few studies have evaluated the sleep profile in preschool-age children with DS. The aim of the current study was to assess the association between sleep disturbances and behavioral problems in a group of preschool-age children with DS, by means of a feasible and easy-to-administer parent-report questionnaires. Seventy-one preschool-age children with DS, ranging in age from 3 to 5.11 years, were included in this retrospective study. Sleep disturbances were evaluated by means of the Sleep Disturbance Scale for Children, while emotional and behavioral problems by means of the Child Behavior Checklist. Sleep breathing disorders were the most frequent sleep difficulties reported by parents. Moreover, children with clinical scores in total sleep problems exhibited elevation of psychopathological symptoms, namely Total problems, Affective problems, Anxiety problems, Pervasive Developmental Problems, and Attention Deficit/Hyperactivity Problems. The identification of the broader connection between sleep difficulties and emotional and behavioral problems in preschool-age children with DS leads to important considerations for intervention.

Abstract
BACKGROUND Sleep disorders are commonly observed in children with Down syndrome (DS) and can lead to significant behavioral and cognitive morbidities in these individuals. OBJECTIVE To perform a systematic review evaluating sleep disorders in individuals with DS. METHODS Search strategies were based on combinations of keywords: "Down syndrome"; "trisomy 21"; "sleep disorders"; "dyssomnias"; "sleep apnea"; "obstructive"; "sleeplessness"; "insomnia"; "parasomnias"; and "excessive daytime sleepiness". PubMed and Science Direct were used. Only original studies and retrospective reviews in English published between January 2011 and March 2021 were included. RESULTS 52 articles were included, most of them involving children and adolescents under 18 years of age. The main sleep disorder associated with DS was obstructive sleep apnea (OSA). Some studies reported the presence of cognitive dysfunction in patients with DS and sleep-disordered breathing, and few have been found about parasomnia, insomnia, and daytime sleepiness in these patients. Movement disorders and unusual postures during sleep may be related to disordered sleep breathing in DS. The main treatment options for OSA are continuous positive airway pressure therapy (CPAP), surgery, and weight control. Computational modeling associated with MRI has been used to plan surgical interventions in these patients. CONCLUSIONS Individuals with DS are at high risk of developing sleep-related breathing disorders. The main sleep disorder associated with DS was OSA. The presence of sleep-disordered breathing contributes to a worsening of cognitive function in patients with DS.

Abstract
OBJECTIVES To assess sleep positions in children with both Down syndrome (DS) and obstructive sleep apnea (OSA) and determine if there is a preferred sleep position by severity of apnea. METHODS A single-center retrospective review of patients with both DS and OSA was performed. Caregivers reported sleep position utilized greater than 50% of observed sleep time. Accuracy of this report was confirmed through review of hypnograms from polysomnography studies. RESULTS Eighty-two patients met inclusion criteria. Median body mass index (BMI) was 26.6 and 56% of patients had a prior tonsillectomy and/or adenoidectomy. The mean obstructive AHI (OAHI) was 25.33 with 90.4% having severe OSA, 9.6% having moderate OSA, and no patients having mild OSA. Reported sleep positions were skewed towards lateral/decubitus (82.9%) compared to prone (11.0%) and supine (6.1%). This was consistent with hypnogram data where 71% of total sleep time in lateral/decubitus positions compared to prone (13%) and supine (6%). The median changes in sleep position per patient was 5 (IQR: 3-6). Lower BMI (p < 0.001, 95% CI: 0.32-1.13) and tonsillectomy (p < 0.001, 95% CI: 7.7-18.19) were associated with lower OAHI. Sleep position was not associated with age (p = 0.19), sex (p = 0.66), race (p = 0.10), ethnicity (p = 0.68) nor history of tonsillectomy (p = 0.34). Preferred sleep position was not correlated with OAHI (p = 0.78, r = 0.03) or OSA severity (p = 0.72, r = 0.03). CONCLUSIONS This study highlights the possibility that children with DS may have preferential sleep positions that cater to optimized airflow in the context of OSA although further prospective study is needed.

Abstract
AIMS To highlight the contributions of Australian and New Zealand researchers to the identification of the consequences of paediatric sleep disordered breathing (SDB). METHODS A search was conducted in PubMed using the terms "sleep disordered breathing" "child" and "Australia or New Zealand". All abstracts were reviewed and those which focused on the consequences of SDB have been included. RESULTS Australasian research into the consequences of SDB has grown exponentially over the last 35 years. SDB has significant adverse consequences for quality of life, behaviour, neurocognition and the cardiovascular system and the Australasian research studies investigating these are summarised. CONCLUSIONS Australian and New Zealand researchers have played a significant role in understanding the consequences of paediatric SDB and the mechanisms which underpin these. The research conducted "Downunder" has led the world in this field of research and will continue to provide evidence to improve the lives of children not only in Australasia but around the world.

Abstract
Children with cleft and craniofacial conditions commonly present with concurrent airway anomalies, which often manifest as sleep disordered breathing. Craniofacial surgeons and members of the multidisciplinary team involved in the care of these patients should appreciate and understand the scope of airway pathology as well as the proper means of airway assessment. This review article details the prevalence and assessment of sleep disordered breathing in patients with craniofacial anomalies, with emphasis on indications, limitations, and interpretation of polysomnography.

Abstract
STUDY OBJECTIVES Positional obstructive sleep apnea (POSA) is a phenotype of obstructive sleep apnea (OSA) where sleep-related obstructive events occur predominantly in the supine position. Limited knowledge exists regarding the presence of POSA in children with obesity. The study objective was to determine the prevalence of POSA while identifying factors associated with POSA in children with obesity. METHODS This was a cross-sectional study of children with obesity, aged 8 to 18 years, with a diagnostic polysomnogram (PSG) between 2012 to 2019, who were referred for the evaluation of sleep-related breathing. POSA was defined as an overall obstructive apnea-hypopnea index (OAHI) ≥5 events/h and a supine OAHI to nonsupine OAHI ratio of ≥2. Patient demographics, anthropometrics, and PSG data were recorded. RESULTS Of the 112 children with obesity with a diagnostic PSG, 43 (38%) had OSA. Among those with OSA, 25 of 43 (58%) had POSA (mean age: 14.6 ± 2.3 years; mean body mass index: 37.7 ± 7.6 kg/m²; 68% male) and 18 of 43 (42%) had non-POSA (mean age: 13.9 ± 2.8 years; mean body mass index: 37.9 ± 7.2 kg/m²; 78% male). Among those with POSA, 13 of 25 (52%) had mild OSA, 7 of 25 (28%) had moderate OSA, and 5 of 25 (20%) had severe OSA. No significant differences were found in age, sex, and anthropometric measures between POSA and non-POSA groups. Time spent in supine and nonsupine sleep did not differ significantly between groups. CONCLUSIONS In children with obesity and OSA, POSA occurs frequently. Identifying POSA allows for potential targeted positional therapy for children with obesity.

Abstract
OBJECTIVE Positional obstructive sleep apnea (POSA)-defined as obstructive sleep apnea twice as severe supine than nonsupine-may offer clues to the underlying pattern of upper airway collapse in children. We compared drug-induced sleep endoscopy (DISE) findings in children with and without POSA. We hypothesized that children with POSA would have significantly higher obstruction at the gravity-dependent palate and tongue base but not at the adenoid, lateral wall, or supraglottis. STUDY DESIGN Retrospective case series. SETTING Tertiary pediatric hospital. SUBJECTS AND METHODS We included children aged 1 to 12 years with obstructive sleep apnea diagnosed by polysomnography who underwent DISE from July 2014 to February 2019. Scores were dichotomized as ≥50% obstruction (Chan-Parikh 2 or 3) vs <50% obstruction (Chan-Parikh 0 or 1). RESULTS Of 99 children included, 32 (32%) had POSA and 67 (68%) did not. Children with POSA did not differ from children without POSA in age, overall apnea-hypopnea index, sex, race, syndromic diagnoses, obesity, or history of adenotonsillectomy. In logistic regression models, odds of ≥50% obstruction were significantly higher at the tongue base (odds ratio, 2.77; 95% CI, 1.04-7.39) after adjustment for age, sex, obesity, previous adenotonsillectomy, and syndrome. No difference was noted at the adenoid, velum, lateral wall, or supraglottis. CONCLUSION POSA was associated with higher odds of obstruction on DISE at the tongue base but not at other levels.

Abstract
BACKGROUND Sleep problems are common among children with Down syndrome (DS), and they can have a serious impact on children with DS as well as their parents and other family members. Specific aims of this study were to evaluate parent-reported sleep problems in children with DS and to examine the relationship between the sleep behaviour of children with DS and their parents' quality of life (QOL). METHOD A cross-sectional survey was conducted in September and October of 2017. Parents of children with DS were recruited from an online self-support community for parents of children with DS in South Korea. The mean age of the parents and children with DS was 40.40 years (SD = 5.09) and 7.89 years (SD = 3.03), respectively. Children's sleep problems and parents' QOL were assessed using the Children's Sleep Habits Questionnaire and the abbreviated version of the World Health Organization Quality of Life scale, respectively. RESULTS Results revealed that 83% of the parents reported that their child with DS experienced sleep problems. Children with DS had significantly more bedtime resistance, night waking, parasomnias and sleep-disordered breathing than did typically developing children. In addition, their Children's Sleep Habits Questionnaire scores were higher than those of typically developing children. Moreover, being older, being male and having more severe developmental delays were significant risk factors for sleep problems among children with DS. Furthermore, sleep problems in children with DS negatively affected parents' QOL. CONCLUSIONS Sleep problems negatively affect children with DS as well as their parents; therefore, health care providers should be aware of these issues and help parents manage sleep problems proactively.

Obstructive events in children with Prader-Willi syndrome occur predominantly during rapid eye movement sleep. Sleep Med 2018; 54:43-47. [PMID: 30529776 DOI: 10.1016/j.sleep.2018.09.026] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Revised: 09/26/2018] [Accepted: 09/29/2018] [Indexed: 12/11/2022]
Abstract
OBJECTIVE Children with Prader-Willi syndrome (PWS) have a high prevalence of obstructive sleep apnea syndrome (OSAS). In most typically developing children with OSAS, more obstructive apneas and hypopneas occur during rapid eye movement (REM) than during non-REM (NREM) sleep. It was hypothesized that patients with PWS are even more prone to obstructive events in REM sleep than otherwise healthy subjects with OSAS. METHODS Polysomnographic data of patients with PWS and of typically developing children (controls) with OSAS (apnea-hypopnea index [AHI] > 1 episode/h) were analyzed. The two groups were compared regarding obstructive AHI (OAHI), OAHI during NREM sleep (OAHInrem), OAHI during REM sleep (OAHIrem), and the OAHIrem/OAHI ratio (outcome measures). The association between PWS diagnosis and OAHIrem/OAHI was adjusted for confounders using a general linear model. RESULTS Twelve children with PWS (median age 7.1 years [interquartile range 3.5, 12.4 years]) and 53 controls (6.5 years [3.9, 8.7 years]) were studied. Children with PWS and controls were similar regarding OAHI (p = 0.21) and OAHInrem (p = 0.76). However, subjects with PWS had higher OAHIrem (17.6 episodes/h [5.8, 25.8 episodes/h]) and OAHIrem/OAHI (2.3 [1.5, 3.2]) than controls (5 episodes/h [1.5, 8.1 episodes/h]; p = 0.002 and 1 [0.5, 2]; p = 0.003, respectively). The association between PWS diagnosis and higher OAHIrem/OAHI persisted after adjustment for age, gender, and obesity (p = 0.009). CONCLUSION In children with PWS, OAHI calculated for total sleep time does not reflect OSAS severity during REM sleep, which on average can be twice as high. Mild OSAS in patients with PWS demonstrated by polygraphy without sleep staging may correspond to a moderately-to-severely increased OAHIrem.

A nationwide, cross-sectional survey on unusual sleep postures and sleep-disordered breathing-related symptoms in people with Down syndrome. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2017; 61:656-667.

Abstract
BACKGROUND People with Down syndrome (DS) often have sleep-disordered breathing (SDB). Unusual sleep postures, such as leaning forward and sitting, are observed in people with DS. This study aimed to clarify the prevalence of unusual sleep postures and their relationships with SDB-related symptoms (SDB-RSs), such as snoring, witnessed apnoea, nocturnal awakening and excessive daytime sleepiness. METHODS A questionnaire, including demographic characteristics and the presence of unusual sleep postures, as well as SDB-RSs, was completed by 1149 parents of people with DS from Japan. RESULTS Unusual sleep postures were recorded in 483 (42.0%) people with DS. These participants were significantly younger and had a history of low muscle tone more frequently than people without unusual sleep postures. In all ages, the leaning forward posture was more frequent than sitting. People with DS with unusual sleep postures suffered from SDB-RSs. Those who slept in the sitting posture had more frequent SDB-RSs than did those who slept with the leaning forward posture. Snoring, witnessed apnoea and nocturnal awakening were observed in 73.6, 27.2 and 58.2% of participants, respectively. Snoring increased with aging. Witnessed apnoea was more common in males and in those with hypothyroidism than in females and in those without hypothyroidism. CONCLUSIONS Our study shows that there is a close relationship between unusual sleep postures and SDB-RSs. We recommend that all people with DS with unusual sleep postures should be checked for the presence of SDB.

Sleep Apnea and Hypoventilation in Patients with Down Syndrome: Analysis of 144 Polysomnogram Studies. CHILDREN-BASEL 2017; 4:children4070055. [PMID: 28665356 PMCID: PMC5532547 DOI: 10.3390/children4070055] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/16/2017] [Revised: 06/20/2017] [Accepted: 06/27/2017] [Indexed: 12/04/2022]
Abstract
Patients with Down syndrome (DS) are at risk for both obstructive sleep apnea (OSA) and central sleep apnea (CSA); however, it is unclear how these components evolve as patients age and whether patients are also at risk for hypoventilation. A retrospective review of 144 diagnostic polysomnograms (PSG) in a tertiary care facility over 10 years was conducted. Descriptive data and exploratory correlation analyses were performed. Sleep disordered breathing was common (seen in 78% of patients) with an average apnea-hypopnea index (AHI) = 10. The relative amount of obstructive apnea was positively correlated with age and body mass index (BMI). The relative amount of central sleep apnea was associated with younger age in the very youngest group (0–3 years). Hypoventilation was common occurring in more than 22% of patients and there was a positive correlation between the maximum CO2 and BMI. Sleep disordered breathing, including hypoventilation, was common in patients with DS. The obstructive component increased significantly with age and BMI, while the central component occurred most in the very young age group. Due to the high risk of hypoventilation, which has not been previously highlighted, it may be helpful to consider therapies to target both apnea and hypoventilation in this population.

Abstract
Background Airway compromise is a leading cause of death in unconscious trauma patients. Although endotracheal intubation is regarded as the gold standard treatment, most prehospital providers are not trained to perform ETI in such patients. Therefore, various lateral positions are advocated for unconscious patients, but their use remains controversial in trauma patients. We conducted a systematic review to investigate whether the supine position is associated with loss of airway patency compared to the lateral position. Methods The review protocol was published in the PROSPERO database (Reg. no. CRD42012001190). We performed literature searches in PubMed, Medline, EMBASE, Cochrane Library, CINAHL and British Nursing Index and included studies related to airway patency, reduced level of consciousness and patient position. We conducted meta-analyses, where appropriate. We graded the quality of evidence with the GRADE methodology. The search was updated in June 2014. Results We identified 1,306 publications, 39 of which were included for further analysis. Sixteen of these publications were included in meta-analysis. We did not identify any studies reporting direct outcome measures (mortality or morbidity) related to airway compromise caused by the patient position (lateral vs. supine position) in trauma patients or in any other patient group. In studies reporting only indirect outcome measures, we found moderate evidence of reduced airway patency in the supine vs. the lateral position, which was measured by the apnea/hypopnea index (AHI). For other indirect outcomes, we only found low or very low quality evidence. Conclusions Although concerns other than airway patency may influence how a trauma patient is positioned, our systematic review provides evidence supporting the long held recommendation that unconscious trauma patients should be placed in a lateral position.
