This study aims to identify the prevalence and risk factors of dysphagia in a Chinese cohort of Angelman syndrome (AS).
A structured questionnaire was used to assess the status of patients in a Chinese cohort of AS. Swallowing function was evaluated using the Pediatric Eating Assessment Tool-10, with gastrointestinal symptoms quantified via the Six-item Gastrointestinal Severity Index (6-GSI). To identify potential risk factors, univariable and multivariate logistic regression was performed.
Among 490 patients with AS (median 6 years, interquartile range 4 years), the molecular subtypes of 75.7% of cases were deletions of 15q11-q13. The prevalence of dysphagia reached 56.1%. Patients with dysphagia exhibited lower BMI values compared to nondysphagia cases (15.31 ± 2.87 vs. 15.92 ± 2.91 kg/m, p = 0.021). Multivariate logistic regression analysis identified that uniparental paternal disomy (UPD) was associated with lower odds of dysphagia compared with deletions of 15q11-q13 (OR = 0.34, p = 0.016). Comorbid sleep disorders (OR = 1.79, p = 0.007), gastrointestinal disorders (OR = 1.89, p = 0.003), and increased 6-GSI scores (OR = 1.16, p = 0.044) showed associations with higher odds of dysphagia.
Over half of Chinese patients with AS experience dysphagia, with UPD moderating risk and comorbidities amplifying susceptibility.
本研究旨在确定中国天使综合征（AS）队列中吞咽困难的患病率及危险因素。
采用结构化问卷评估中国AS队列中患者的状况。使用儿童饮食评估工具-10评估吞咽功能，通过六项胃肠道严重程度指数（6-GSI）对胃肠道症状进行量化。为确定潜在危险因素，进行单变量和多变量逻辑回归分析。
在490例AS患者中（中位数6岁，四分位间距4岁），75.7%的病例分子亚型为15q11-q13缺失。吞咽困难的患病率达到56.1%。与无吞咽困难的病例相比，吞咽困难患者的BMI值较低（15.31±2.87 vs. 15.92±2.91kg/m²，p=0.021）。多变量逻辑回归分析确定，与15q11-q13缺失相比，单亲二体性（UPD）与吞咽困难的较低几率相关（OR=0.34，p=0.016）。合并睡眠障碍（OR=1.79，p=0.007）、胃肠道疾病（OR=1.89，p=0.003）和6-GSI评分升高（OR=1.16，p=0.044）与吞咽困难的较高几率相关。
超过半数的中国AS患者存在吞咽困难，UPD降低风险，合并症增加易感性。
