Obstructive sleep apnea in patients with Down syndrome: current perspectives

Area of Science:

• Medical Science
• Genetics
• Sleep Medicine

Background:

• Obstructive sleep apnea (OSA) is a frequent and severe comorbidity in individuals with Down syndrome (DS).
• Anatomic abnormalities, hypotonia, and obesity contribute to increased OSA prevalence and severity in DS.
• Clinical signs and symptoms of OSA in DS often do not correlate with disease presence, necessitating routine screening.

Purpose of the Study:

• To highlight the significance of obstructive sleep apnea (OSA) in individuals with Down syndrome (DS).
• To emphasize the need for early diagnosis and tailored treatment strategies for OSA in the DS population.
• To discuss current and emerging therapeutic options for OSA in DS.

Main Methods:

• Polysomnography remains the gold standard for diagnosing OSA in individuals with DS.
• Evaluation often includes drug-induced sleep endoscopy (DISE) to identify specific sites of airway obstruction.
• Treatment approaches encompass surgical interventions (adenotonsillectomy, advanced airway surgery) and continuous positive airway pressure (CPAP).

Main Results:

• Individuals with DS are more susceptible to cardiovascular and neurocognitive complications from OSA.
• Adenotonsillectomy is a primary surgical option, but residual OSA is common, requiring further investigation.
• Novel therapies like hypoglossal nerve stimulation show promise for refractory OSA.

Conclusions:

• Routine screening for OSA is essential for all individuals with Down syndrome.
• Personalized treatment plans are necessary due to the heterogeneity within the DS population.
• Further research is needed on risk factors, diagnostic methods, and outcome analysis for OSA in DS.
