Abstract
Children with Down syndrome (DS) are at high risk of sleep-disordered breathing (SDB). The American Academy of Pediatrics recommends a polysomnogram (PSG) in children with DS prior to the age of 4. This retrospective study examined the frequency of SDB, gas exchange abnormalities, co-morbidities, and surgical management in children with DS aged 2-4 years old at Seattle Children's Hospital from 2015-2021. A total of 153 children underwent PSG, with 75 meeting the inclusion criteria. The mean age was 3.03 years (SD 0.805), 56% were male, and 54.7% were Caucasian. Comorbidities included (n, %): cardiac (43, 57.3%), dysphagia or aspiration (24, 32.0%), prematurity (17, 22.7%), pulmonary (16, 21.3%), immune dysfunction (2, 2.7%), and hypothyroidism (23, 30.7%). PSG parameter data collected included (mean, SD): obstructive AHI (7.9, 9.4) and central AHI (2.4, 2.4). In total, 94.7% met the criteria for pediatric OSA, 9.5% met the criteria for central apnea, and 9.5% met the criteria for hypoventilation. Only one child met the criteria for hypoxemia. Overall, 60% had surgical intervention, with 88.9% of these being adenotonsillectomy. There was no statistically significant difference in the frequency of OSA at different ages. Children aged 2-4 years with DS have a high frequency of OSA. The most commonly encountered co-morbidities were cardiac and swallowing dysfunction. Among those with OSA, more than half underwent surgical intervention, with improvements in their obstructive apnea hypopnea index, total apnea hypopnea index, oxygen saturation nadir, oxygen desaturation index, total arousal index, and total sleep duration. This highlights the importance of early diagnosis and appropriate treatment. Our study also suggests that adenotonsillar hypertrophy is still a large contributor to upper airway obstruction in this age group.

Abstract
OBJECTIVES Intracapsular tonsillectomy and adenoidectomy (iTA) has become a popular alternative to extracapsular tonsillectomy and adenoidectomy (TT) for the treatment of pediatric obstructive sleep apnea (OSA) due to improved recovery and fewer complications. The objective of this study was to compare surgical recovery and impact on OSA of iTA versus TT in patients with Trisomy 21 (T21). METHODS This is a case series with chart review of all T21 patients who underwent iTA or TT at our institution between July 1, 2015 and August 15, 2022. Data collected included demographics, comorbidities, preoperative sleep studies, intraoperative data, complications and recovery, postoperative sleep studies, and follow-up data. RESULTS There were 62 (21.7%) patients who underwent iTA and 224 (78.3%) patients who underwent TT. The iTA group had significantly lower pain scores (p < 0.001), decreased use of narcotics (p < 0.001), shorter length of stay (p = 0.003), and faster return to oral intake (p = 0.01) during their postoperative hospital admission, and fewer 30-day complications (p = 0.009) compared to the TA group. Both groups showed significant improvements in their sleep studies. For 41 (66.1%) of iTA patients who had follow-up, median follow-up was 1.8 years and for 169 (75.4%) TT patients, median follow-up was 2.6 years. At follow-up, 21 of 41 (51.2%) iTA patients and 83 of 169 (49.1%) TT patients exhibited OSA symptoms (p = 0.084) and tonsillar regrowth was not significantly different between the two groups (p = 0.12). CONCLUSION Patients with T21 experience less pain and fewer postoperative respiratory complications from iTA than from TT. The short-term impact of iTA versus TT on OSA, as measured by poysomnography, does not differ between the two techniques. LEVEL OF EVIDENCE 3 Laryngoscope, 134:2430-2437, 2024.

J Sleep Res 2024; 33:e13946. [PMID: 37226964 DOI: 10.1111/jsr.13946] [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: 04/03/2023] [Revised: 05/05/2023] [Accepted: 05/08/2023] [Indexed: 05/26/2023]
Abstract
Obstructive sleep apnea (OSA) is commonly observed in children with Down syndrome (DS) and may affect their physical and psychological development. Currently, adenotonsillectomy is the first line treatment option for paediatric patients with OSA. However, surgical outcomes for such patients are not satisfactory. In this study, we analysed the efficacy and safety of adenotonsillectomy in the treatment of children with obstructive sleep apnea and Down syndrome. We systematically searched the PubMed, Web of Science, EMBASE, and the Cochrane databases and pooled data from nine relevant studies involving 384 participants. Subsequently, we analysed four outcomes in polysomnography, namely: net postoperative changes in the apnea-hypopnea index (AHI), the minimum oxygen saturation, sleep efficiency, and arousal index. Meta-analysis of the AHI showed a decrease of 7.18 events/h [95% CI (-9.69, -4.67) events/h; p < 0.00001] and an increase in the minimum oxygen saturation of 3.14% [95% CI (1.44, 4.84) %; p = 0.0003]. There was no significant increase in sleep efficiency [MD 1.69%, 95% CI (-0.59, 3.98) %; p = 0.15], but the arousal index significantly decreased by -3.21 events/hour [95% CI (-6.04, -0.38) events/h; p < 0.03]. In addition, the overall success rate was 16% (95% CI, 12%-21%) for postoperative AHI < 1 and 57% (95% CI, 51%-63%) for postoperative AHI <5. The postoperative complications recorded included airway obstruction and bleeding. This study demonstrated the efficacy of adenotonsillectomy as a treatment option for OSA. However, it is important to note that residual OSA and potential postoperative complications require further attention in future studies.

[PMID: 37823584 DOI: 10.1002/lary.31107] [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: 04/03/2023] [Revised: 08/07/2023] [Accepted: 09/28/2023] [Indexed: 10/13/2023]
Abstract
OBJECTIVES The primary aim of this study is to describe a novel surgical technique developed for tongue base suspension (TBS). The second aim of this study is to assess the efficacy of the developed procedure by quantifying preoperative and postoperative polysomnographic outcomes for pediatric patients undergoing fluoroscopic-assisted tongue suspension (FATS) with the Encore System. Our hypothesis is that our FATS technique will provide at least a 50% reduction in the Apnea/Hypopnea Index (AHI), including in the medically complex pediatric population. STUDY DESIGN Retrospective case series. METHODS An electronic medical record review was conducted of patients who underwent FATS by a single surgeon at a tertiary care medical center between December 2019 and June 2022. Inclusion criteria included all patients <18 years old with evidence of OSA or sleep-disordered breathing and who had glossoptosis on sleep endoscopy. Data extracted from the medical record included age, gender, medical comorbidity history, reason for referral, history of airway surgeries, length of hospital stay, surgical complications data, and preoperative and postoperative polysomnographic data. Surgical success was defined by at least a 50% reduction in AHI. RESULTS Thirty patients (53.3% male) with a mean age of 6.3 (±5.3, 0.16-17) years underwent FATS over the study period. Most patients (93%) had an underlying comorbidity: cerebral palsy (37%), chromosomal abnormalities (23%), Down syndrome (13%), Pierre-Robin sequence (10%), and obesity (10%). The majority of patients (77%) were explicitly referred for tracheostomy placement secondary to failed management of OSA. 21 patients completed both preoperative and postoperative polysomnograms. The mean preoperative AHI, obstructive AHI (oAHI), and respiratory disturbance index (RDI) were 28.8 (±19.8), 30.8 (±19.6), and 30.5 (±19.3), respectively. The mean postoperative AHI, oAHI, and RDI were 7.3 (±9.2), 7.5 (±9.1), and 7.9 (±9.3), respectively. The mean change in AHI was -21.5 (±21.4) events/h (p < 0.01, 95% CI -29.0 to -11.4 events/h). The mean percentage decrease in AHI was 74.7%. The mean change in oAHI and RDI were -23.3 (±21.9) events/h (p < 0.01 95% CI- 39.9 to -21.4 events/h) and -22.5 (±21.5) events/h (p < 0.01, 95% CI- 31.5 to -12.4 events/h), respectively. The mean percentage decrease in oAHI and RDI was 75.6% and 73.8%, respectively. Surgical success occurred in 16 of the 21 (76%) patients. Of the 23 patients referred explicitly for tracheostomy placement, 21 (91%) were able to avoid tracheostomy placement secondary to improvements in OSA. CONCLUSIONS Patients undergoing fluoroscopic-assisted TBS revealed statistically significant improvements in AHI, oAHI, and RDI, with an overall surgical success rate of 76%. Complication rates were minimal, despite the complex nature of the study population. FATS should be considered a viable surgical approach in pediatric patients with an identified base of tongue obstruction and OSA. LEVEL OF EVIDENCE 4 Laryngoscope, 134:S1-S9, 2024.

Abstract
In this case study, a 16-year-old male with Down syndrome (DS) faced persistent nocturnal seizures despite anti-seizure medications and treatment for concurrent hypothyroidism. Obstructive sleep apnea (OSA), a common issue in patients with Down syndrome, was revealed as a trigger of the seizures. The implementation of continuous positive airway pressure (CPAP) therapy along with medication adjustments led to a significant decrease in seizure frequency, highlighting the importance of a comprehensive approach to seizure management in patients with complex medical conditions.

Abstract
OBJECTIVE To better understand the long-term health implications of obstructive sleep apnea (OSA) on patients with Trisomy 21 (T21) and the role of sleep surgery as a therapeutic intervention. STUDY DESIGN Retrospective large database review. SETTING The prevalence of OSA is as high as 75% in patients with T21. We sought to examine the cardiovascular, neurological, and endocrinological outcomes of patients with T21 10 years after their diagnosis of OSA. METHODS TriNetX, an electronic medical record database, was queried for health outcomes in patients with T21 after diagnosis of OSA. The group was further analyzed to identify those who underwent sleep surgery, including hypoglossal nerve stimulation, palatopharyngoplasty, or adenotonsillectomy. RESULTS Ten years after diagnosis, patients with OSA and T21 had a significantly higher incidence of death, myocardial infarction, cerebral infarction, heart failure, cardiac arrhythmia, ischemic heart disease, atrial fibrillation, essential hypertension, pulmonary hypertension, diabetes mellitus, and Alzheimer's disease compared to patients with T21 alone. Patients with OSA and T21 who underwent sleep surgery had significantly reduced incidence of adverse health outcomes compared to patients using continuous positive airway pressure. CONCLUSION Our findings suggest that patients with T21 and OSA are at higher risk of poor health outcomes, which may require closer monitoring for earlier diagnosis and management of comorbid conditions. Sleep surgery is a suitable treatment modality for mitigating the risk of adverse outcomes in this population and should be considered in patients who are eligible surgical candidates.

Abstract
BACKGROUND Obstructive sleep apnoea (OSA) is common in children and adolescents with Down syndrome (DS). Clinical guidelines recommend that all children with DS have polysomnography (PSG) for assessment of OSA by the age of 4 years, but access is limited and testing may be burdensome for children and families. METHODS The purpose of this prospective cross-sectional cohort study was to identify a model to predict OSA in this group that could be tested in an external population to triage children and adolescents with DS for PSG. These models were based on a comprehensive set of potential predictive demographic, anthropometric, quality of life and sleep-related variables. RESULTS The results of this study show the predictive power of a model based on the sleep disordered breathing subscale of the Pediatric Sleep Survey Instrument and sleep fragmentation quantified using actigraphy in determining moderate-severe OSA in children and adolescents with DS. This model exhibits high sensitivity (82%), specificity (80%), positive predictive value (75%) and negative predictive value (86%). CONCLUSIONS We demonstrate the utility of a tool containing the sleep disordered breathing subscale of the Pediatric Sleep Survey Instrument and sleep fragmentation quantified using actigraphy in identifying children and adolescents with DS who have moderate/severe OSA.

Abstract
OBJECTIVES Obstructive sleep apnea (OSA) is highly prevalent among individuals with Down syndrome (DS), and the nonphysiological consequences of OSA require examination to inform treatment planning. This study aimed to investigate the association between OSA and aspects of language, executive functioning, behavioral, social abilities, and sleep problems in youth with DS aged 6 to 17 years. METHODS Multivariate analysis of covariance was used to compare 3 groups adjusted for age, participants with DS with untreated OSA (n = 28), participants with DS without OSA (n = 38), and participants with DS with treated OSA (n = 34). To be eligible for the study, participants had to have an estimated mental age of 3 years. No children were excluded based on estimated mental age. RESULTS After adjusting for age, participants with untreated OSA showed a common pattern of lower estimated marginal mean scores than those with treated OSA and those with no OSA in expressive and receptive vocabulary and higher estimated marginal mean scores with executive functions, everyday memory, attention, internalizing and externalizing behavior, social behavior, and sleep problems. However, only the group differences for executive function (emotional regulation) and internalizing behavior were statistically significant. CONCLUSION Study findings corroborate and extend prior findings related to OSA and clinical outcomes for youth with DS. The study highlights the importance of OSA treatment in youth with DS and provides clinical recommendations for this population. Additional studies are necessary to control the effects of health and demographic variables.

Abstract
INTRODUCTION Children with Down Syndrome (DS) are at high risk of sleep disordered breathing (SDB). We aimed to examine the burden of SDB in infants with DS referred to tertiary sleep center. METHODS Infants (≤12 months old) with DS who underwent consecutive polysomnography (PSG) at a single academic sleep center over a 6-year period were included. obstructive sleep apnea (OSA) (obstructive apnea hypopnea index [oAHI]>1/hr), central sleep apnea (central apnea index > 5/h) and the presence of hypoventilation (% time spent with CO2 > 50 mmHg either by end-tidal or transcutaneous> 25% of total sleep time) and hypoxemia (time spent with O2 saturation <88% >5 min) were ascertained. RESULTS A total of 40 infants were included (Mean age 6.6 months, male 66%). PSGs consisted of diagnostic (n = 13) and split night (n = 27, 68%) studies. All met criteria for OSA with mean oAHI 34.6/h (32.3). Central sleep apnea was present in 11 (27.5%) of infants. A total of 11 (27.5%) had hypoxemia. Hypoventilation was present in 10 (25%) infants. CONCLUSION This study highlights the high prevalence of SDB in infants with DS referred to a sleep center, and supports early PSG assessment in this patient population.

Abstract
Background Congenital heart diseases (CHD) are common in Down syndrome patients who will often have additional anomalies, in which the presence of them and their management are expected to impact their quality of life (QoL). There are limited studies trying to evaluate the impact of CHD on the QoL in children with Down syndrome. Methods The present study comprised 97 Down syndrome children. The children's parents responded to phone interviews filling out TNO-AZL (Netherlands Organisation for Applied Scientific Research Academic Medical Centre) Preschool Quality of Life (TAPQOL) and TNO-AZL Child Quality of Life Parent Form (TACQOL-PF) questionnaires. Children were divided into two groups according to their age: group A (one to five years) and group B (six to 15 years). The results were analyzed using Statistical Package for Social Sciences (SPSS) software, version 21 (IBM Corp., Armonk, NY). Results CHD negatively affected motor skills in younger but not older children. All other QoL-related parameters were unaffected by CHD. Conclusion Down syndrome children with CHD demonstrated similar QoL to Down syndrome children without CHD, with the exception of having a lower motor outcome as infants/toddlers. This difference improved with time and did not exist in older children.

Abstract
Background: Children with Down syndrome (DS) are at increased risk of obstructive sleep disordered breathing (SDB), which is associated with intermittent hypoxia and sleep disruption affecting daytime functioning. We aimed to examine the effects of treatment of SDB on sleep quality and daytime functioning in children with DS. Methods: Children with DS and SDB (n = 24) completed a baseline and follow-up overnight polysomnographic (PSG) study 22 ± 7 months (mean ± SD) later. Sleep micro-architecture was assessed using EEG spectral analysis, and parents completed a number of questionnaires assessing sleep, behavior, daytime functioning, and quality of life (QOL). Results: A total of nine children (38%) were treated. At baseline, the treated group had more severe SDB compared to the untreated group. SDB severity was significantly improved from 40.3 ± 46.9 events/h to 17.9 ± 26.9 events/h (p < 0.01) at follow up in children who were treated. There were no significant differences in sleep macro-architecture parameters from baseline to follow up in either the treated or untreated group. Sleep micro-architecture was not different between studies in the treated group, however this tended to improve in the untreated group, particularly in REM sleep. Daytime functioning and behavior were not different between the studies in either group, however, QOL improved after treatment. Conclusions: Our study identified that treatment of SDB improves severity of the disease as defined by PSG, and this was associated with parental reports of improved QOL, despite treatment having no demonstrable impacts on sleep quality, behavior, or daytime functioning.

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
STUDY OBJECTIVES Children with Down syndrome (DS) are at risk of obstructive sleep apnea (OSA), but the access to sleep lab polysomnography (PSG) is limited. Simplified techniques are needed, such as polygraphy coupled with pulse transit time (PTT-PG) that detects respiratory events and the total autonomic arousals index (PTTAI). Our objective was to assess the ability of PTT-PG compared with PSG to diagnose OSA in children with DS. METHODS In this prospective multicenter study, patients with DS underwent a full-night PSG coupled with PTT. Sleep questionnaires (Sleep Disturbance Scale for Children and Pediatric Sleep Questionnaire) were filled by parents. PSG and PTT-PG results were compared to test their sensibility and specificity to diagnose OSA. RESULTS A total of 53 patients with DS were included; their median age was 9.3 years. An obstructive apnea-hypopnea index (OAHI) by PSG > 1 event/h was found in 36 (68%) patients, OAHI was > 1 and < 5 events/h in 18 patients (34%), ≥ 5 and < 10 events/h in 11 patients (21%), and ≥ 10 events/h in 7 patients (13%). OAHI was larger on PSG than on PTT-PG (P = .0005). For OSA diagnosis, the sensitivity was excellent for OAHI by PTT-PG if the added total PTTAI was > 1 event/h (1.0) and the specificity was high for the Pediatric Sleep Questionnaire (0.88) and OAHI > 1 event/h on PTT-PG (1.0). CONCLUSIONS More than two-thirds of children with DS referred for screening by a genetics specialist had OSA diagnosed by PSG. With its excellent sensitivity and specificity, PTT-PG could be a good and simplified alternative to PSG to diagnose OSA in children with DS. CITATION Ioan I, Weick D, Sevin F, et al.

Abstract
BACKGROUND Children with Trisomy 21 (T21) are at an increased risk of sleep-disordered breathing (SDB), which can impact daily functioning and cause other health complications. Accordingly, it is imperative to diagnose and treat SDB in this population. Current guidelines recommend screening polysomnogram by age 4 or sooner if clinically indicated. There are limited published studies describing characteristics of SDB in children with T21, particularly in infants and young children. OBJECTIVE The objective of this study is to characterize SDB and treatment modalities in infants and young children with T21. METHODS This is a retrospective review of a cohort of children (≤60 months of age) with T21 who completed a polysomnogram (PSG) between 2015 and 2020 at a pediatric referral center. Demographic information, relevant medical history, polysomnography parameters, and treatment details of these children were collected from EMR. Descriptive and comparative statistics were calculated for the cohort; additional subgroup analysis was completed by age 0-35 months and 36-60 months. RESULTS Most of the cohort met criteria for sleep apnea (84.1%), and airway surgery was the most common treatment modality (71.4%). The mean AHI was high (21.4 events/hour) with a trend towards hypoventilation (mean EtCO2 = 55.9 mmHg; mean percentage of TST with EtCO2 > 50 mmHg 20.8%). Mean arousal index was elevated (32 events/hour). There were no significant differences in SDB by age when we compared children 0-35 months and 36-60 months. CONCLUSIONS This cohort of referred children with T21 showed high prevalence of SDB with a trend towards hypoventilation and disrupted sleep quality with no significant differences by age. These data highlight the importance of maintaining a high index of suspicion for SDB in young patients with T21 and obtaining PSG testing to characterize sleep and breathing.

Abstract
Children with Down syndrome (DS) are at high risk for developing obstructive sleep apnea (OSA) compared to children without DS. The negative impact of OSA on health, behavior, and cognitive development in children with DS highlights the importance of timely and effective treatment. Due to the higher prevalence of craniofacial and airway abnormalities, obesity, and hypotonia in patients with DS, residual OSA can still occur after exhausting first-line options. While treatment commonly includes adenotonsillectomy (AT) and continuous positive airway pressure (CPAP) therapy, additional therapy such as medical management and/or adjuvant surgical procedures need to be considered in refractory OSA. Given the significant comorbidities secondary to untreated OSA in children with DS, such as cardiovascular and neurobehavioral consequences, more robust randomized trials in this patient population are needed to produce treatment guidelines separate from those for the general pediatric population of otherwise healthy children with OSA. Further studies are also needed to look at desensitization and optimization of CPAP use in patients with DS and OSA.

Abstract
OBJECTIVE To observe the degree of airway collapse at varying levels of continuous positive airway pressure (CPAP) during drug pediatric induced sleep endoscopy. METHODS Using our institutional anesthesia protocol for pediatric DISE procedures, patients were anesthetized followed by evaluation of the nasal airway, nasopharynx, velum, hypopharynx, arytenoids, tongue base, and epiglottis. CPAP titration was performed under vision to evaluate the degree of airway collapse at the level of the velum. Comparison was made with pre-operative polysomnography findings. RESULTS Twelve pediatric patients underwent DISE with intraoperative CPAP titration. In 7/12 patients, DISE observed CPAP titration was beneficial in elucidating areas of obstruction that were observed at pressures beyond those recommended during preoperative sleep study titrations. In 3 patients, DISE observations provided a basis for evaluation in children not compliant with sleep study CPAP titration testing. With regard to regions effected, airway collapse was observed at the velum and oropharynx to a greater degree when compared with the tongue base and epiglottis. CONCLUSION DISE evaluation of the pediatric patient with obstructive sleep apnea may present a source for further patient evaluation with respect to CPAP optimization and severity of OSA assessment, particularly in syndromic patients.

Abstract
BACKGROUND Sanjad Sakati syndrome (SSS) is a rare autosomal recessive genetic disorder caused by mutation in TBCE (tubulin folding cofactor E) gene. Reported cases were almost exclusively of Middle-Eastern and Arabian children of consanguineous parents. We report the clinical manifestations, outcome, and an observed new association of sleep-disordered breathing (SDB) among children with Sanjad Sakati syndrome. METHODS Clinical and routine laboratory data of SSS cases attending Sultan Qaboos University Hospital, Oman, were collected from the electronic patient records or through direct clinic interviews. In-lab polysomnography (PSG) and echocardiography were carried out for all the cases. SDB diagnosis was based on the guidelines of the American Academy of Sleep Medicine. RESULTS Of 12 patients with SSS, 5 males (42%), all of them (100%) had obstructive sleep apnea (OSA) and 4 of them (33%) had additional significant central apnea and sleep-related hypoventilation. Eight patients (67%) had severe SDB with mean apnea-hypopnea index (AHI) of 26.5 events/h. Age at time of diagnosis with SDB ranged from 2 to 17 years with mean of 8.9 [Formula: see text] Two patients had severe pulmonary hypertension as a complication of severe SDB and died from type 2 respiratory failure. CONCLUSIONS Sleep-disordered breathing is prevalent among children with SSS, especially OSA. This is the first study to report SDB in a large cohort of patients with this extremely rare syndrome. The study results encourage the importance of screening affected patients with SSS for sleep-disordered breathing early before developing severe morbidities such as pulmonary hypertension that further compromise their quality of life.

Abstract
BACKGROUND Trisomy 21 (TS21) is a condition with a high risk for sleep apnea. In the pediatric population, the risk also includes central breathing disorders. The aim of this study was to define the clinical and polysomnographic characteristics of central apnea in infants, children, and adolescents with TS21. METHODS Retrospective review of baseline polysomnograms (PSGs) in children with TS21 in the sleep center at Children's National Medical Center in Washington DC. RESULTS We included a total of 158 infants, children, and adolescents (0-18 years) with TS21 in this study. The median age was 4.82 years and 62% were male. The primary findings of the study are that (1) 12% of all pediatric subjects with TS21 included had a central apnea index (CAI) > 2/h; (2) the proportion of TS21 individuals with central breathing abnormalities progressively decreased with age being common in young individuals (≤2 years of age) but rare after 10 years of age; (3) additional sleep breathing disturbances (e.g., OSA and/or hypoxemia) are often present in children with TS21 and central apnea; and (4) the prevalence of central breathing abnormalities in TS21 is influenced by sex, being more likely to persist beyond early childhood (>2 years of age) in females than in males. CONCLUSION Central breathing abnormalities are common in TS21 among young children (≤2 years of age) and in females older than 2 years of age. Central apnea is often associated with concomitant obstructive sleep apnea and/or hypoxemia in children with TS21.

Abstract
OBJECTIVES Given that 30%-50% of children with trisomy 21 have persistent obstructive sleep apnoea (OSA) after adenotonsillectomy, we evaluated whether demographic, clinical and polysomnographic factors predicted persistent OSA and OSA severity after adenotonsillectomy. DESIGN Retrospective study. SETTING Secondary care hospital. PARTICIPANTS Retrospective review of 32 children with the diagnosis of trisomy 21 and OSA by polysomnography who underwent adenotonsillectomy, from January 2010 to December 2018. MAIN OUTCOME AND MEASURE Non-parametric analysis was used to compare pre- and postoperative factors, and regression was used to model persistent OSA and OSA severity. RESULTS Thirty-two children were included (17 males, median age 10.00 ± 8.00 years, median body mass index z-score 0.89 ± 1.25). Overall, adenotonsillectomy resulted in a significant improvement in median obstructive apnoea-hypopnoea index (oAHI) from 7.5 ± 8.95 to 4.40 ± 4.38 events per hour (P < .001) and in median OSA-18 score from 85.00 ± 12.00 to 61.00 ± 37.75 (P < .001). Persistent OSA was found in 56.25% of the children. Univariate regression suggests that postoperative OSA-18 score was associated with persistent OSA after adenotonsillectomy. Preoperative oAHI, preoperative oxygen desaturation index, pre- and postoperative OSA-18 scores correlated with OSA severity after adenotonsillectomy. However, in a multivariate model only the postoperative OSA-18 score correlated with OSA severity after adenotonsillectomy. CONCLUSIONS Although adenotonsillectomy results in a significant improvement of OSA in children with trisomy 21, more than half of the children had persistent OSA. The postoperative OSA-18 score was associated both with persistent OSA and OSA severity after adenotonsillectomy.
