Medications for Obstructive Sleep Apnea to Improve Cognition in Children With Down Syndrome

Obstructive Sleep ApneaDown Syndrome

This is an open-label study of the combination of atomoxetine and oxybutynin (ato-oxy) in children with Down syndrome and obstructive sleep apnea (OSA) documented by polysomnography (PSG). Participants will receive ato-oxy for 6 months. Ato-oxy dose will be 5 mg oxybutynin and 0.5mg/kg/day (max 40 mg) atomoxetine. Dosing of the study treatment will occur approximately 30 minutes prior to bedtime. Participants who withdraw from the study will not be replaced. Study participants will undergo eligibility screening that will include an initial screening to determine whether non- PSG enrollment criteria are met, followed by a 1 night in-lab PSG and health-related quality of life (HRQOL) and cognitive assessment for participants who qualify based on non-PSG criteria. For participants who are eligible and enroll in the study, the screening PSG night will serve as the baseline measure for apnea hypopnea index (AHI) and other PSG endpoints. On the final night of dosing for ato-oxy participants will return for inpatient PSG and health-related quality of life assessment and cognitive assessment. The primary efficacy endpoint is the change in obstructive AHI from baseline.

Blood Flow and Blood Pressure Investigation in Down Syndrome

Down Syndrome

Down syndrome (DS) is a chromosomal condition that occurs in approximately 1 in 800 births worldwide, and causes impairments in physical function, including a reduced work capacity (as measured by VO2peak or aerobic capacity). Work capacity is important for activities of daily living, in order to live longer, healthier lives. Reduced work capacity stems in large part from autonomic dysfunction, which has been described in individuals with DS. Individuals with DS experience reduced sympathetic and parasympathetic control, which results in alterations in resting heart rate, blood pressure, and attenuated responses to sympathoexcitatory stimuli. Autonomic dysfunction may impair the ability to regulate blood flow and blood pressure to working muscles during exercise, which may cause a mismatch between oxygen supply and demand, further compromising the already reduced work capacity observed in individuals with DS. Utilization of a large muscle mass exercise, such as lower-limb dynamic exercise (similar to walking), requires a large shift in blood flow to match metabolic demand and allows the opportunity to evaluate blood flow regulation. Conversely, examination of the large changes in pressure in response to isometric exercise (i.e., a sustained contraction), allows for examination of the exercise pressor reflex as evoked by the isometric contraction. Thus, by comprehensively evaluating blood flow and blood pressure regulation, our work will further elucidate the mechanisms that underlay the reduced work capacity in individuals with DS. Improvement of overall work capacity for a population with reduced work capacity will guide future studies and exercise interventions aimed at helping to improve independence and quality of life, ultimately allowing individuals with DS to live longer, healthier lives. Aim 1 (Dynamic Exercise): To examine the effects of an acute bout of dynamic leg kicking at both relative and absolute intensity workloads on femoral blood flow to both exercising and non-exercising muscle, in individuals with and without DS. Aim 2 (Isometric Exercise): To examine the exercise pressor response to lower limb isometric exercise in individuals with and without DS.

Treatment of Obstructive Sleep Apnea With Personalized Surgery in Children With Down Syndrome (TOPS-DS)...

Obstructive Sleep ApneaDown Syndrome

The overall objective of this randomized clinical trial is to test the effectiveness of a personalized approach to the surgical treatment of OSA in children with Down syndrome (DS).The estimated prevalence of obstructive sleep apnea (OSA) in children with DS ranges from 45-83%, compared to 1-6% in the general pediatric population. Untreated OSA in children has been associated with daytime sleepiness, cognitive or behavioral problems, and cardiovascular complications, all which are common in children with DS. Adenotonsillectomy (AT) is the first line treatment for OSA in children, however, most large studies of AT outcomes have excluded children with DS. Available evidence demonstrates that AT is far less effective in children with DS than in the general pediatric population, with 48 to 95% of children with DS having persistent OSA after AT. Medical treatments such as positive airway pressure (PAP) therapy are frequently inadequate or poorly tolerated in this population, so many children with DS and OSA remain untreated. Drug-induced sleep endoscopy (DISE) enables direct observation of the sites and patterns of obstruction during sedated sleep using a flexible endoscope passed through the nose into the pharynx. DISE was developed to guide surgical decisions in adult OSA, and in recent years has also been used to design personalized surgical interventions in children. Using this DISE Rating Scale, the investigators have demonstrated that children with DS are more prone to tongue base and supraglottic obstruction than non-DS children, suggesting the need for more personalized surgical treatments that are tailored to the common sources of obstruction in this population. Several small case series demonstrate that DISE-directed surgery can be effective in treating OSA in children with DS. However, because there have been few prospective studies and no randomized trials comparing different treatment options in this population, there remains uncertainty about whether such a personalized approach leads to superior outcomes compared to the first line AT. It is the investigators' hypothesis that personalized DISE-directed surgery that uses existing procedures to address specific fixed and dynamic anatomic features causing obstruction in each child with DS will be superior to the current first line approach of AT. This novel approach may improve OSA outcomes and reduce the burden of unnecessary AT or secondary surgery for persistent OSA after an ineffective AT.

Oxygen Uptake Kinetics During Submaximal Exercise in Adults With Down Syndrome

Down Syndrome

This study aims to compare the rate at which oxygen uptake adapts to submaximal, moderate intensity exercise (oxygen uptake kinetics) between adults with and without Down syndrome, to determine the contribution of oxygen uptake kinetics to exercise intolerance of adults with Down syndrome. Additionally, the study will investigate the role of oxygen delivery (by the cardiovascular circuit) and oxygen utilization (in the mitochondria) on the oxygen uptake kinetics of adults with Down syndrome to identify specific areas which adults with Down syndrome could benefit from targeting during exercise training. Overall, this study aims to contribute to the knowledge on the exercise capacity of adults with Down syndrome, in order to improve the way adults with Down syndrome participate in and benefit from exercise. Participants will perform a maximal exercise test on a treadmill, and walk on a treadmill at a submaximal, moderate intensity speed and incline, during which oxygen uptake at the lungs, cardiac output, and oxygen utilization in the muscle will be measured.

Parent-Infant Inter(X)Action Intervention (PIXI)

Fragile X SyndromeAngelman Syndrome12 more

The objective is to develop and test, through an iterative process, an intervention to address and support the development of infants with a confirmed diagnosis of neurogenetic disorders that leave individuals at risk for developmental delays or intellectual and developmental disabilities. The proposed project will capitalize and expand upon existing empirically based interventions designed to improve outcomes for infants with suspected developmental delays. Participants will be infants with a confirmed diagnosis of a neurogenetic disorder (e.g., fragile X, Angelman, Prader-Willi, Dup15q, Phelan-McDermid, Rhett, Smith Magenis, Williams, Turner, Kleinfelter, Down syndromes, Duchenne muscular dystrophy) within the first year of life and their parents/caregivers. The intervention, called Parent-infant Inter(X)action Intervention (PIXI) is a comprehensive program inclusive of parent education about early infant development and the neurogenetic disorder for which they were diagnosed, direct parent coaching around parent-child interaction, and family/parent well-being support. The protocol includes repeated comprehensive assessments of family and child functioning, along with an examination of feasibility and acceptability of the program.
