Abstract

Study objectives: Catathrenia has been classified as a sleep-related breathing disorder variant in the third edition of the International Classification of Sleep Disorders, but its validity remains unverified. We analyzed the clinical descriptive variables and polysomnographic findings of catathrenia and discussed the similarities and differences to those of obstructive sleep apnea (OSA), non-REM parasomnias, and sleep bruxism (SB).

Methods: A retrospective analysis was conducted on 47 patients diagnosed with nocturnal groaning through polysomnography. We examined sex, body mass index, age at symptom onset, weekly symptom frequency, and presence/absence of comorbidities, including OSA, periodic limb movement disorder, non-REM parasomnia, and SB. The groaning event (GE) index was calculated according to sleep position and sleep stage.

Results: The distribution of patients with catathrenia did not show sex difference (male/female = 20:27), body mass index was 20.6 ± 3.0 kg/m2, and age of onset was 18.2 ± 7.4 years. The GE index was higher in stages N1 and R than in stage N3 and in the supine position than in the lateral position. There were no cases complicated with non-REM parasomnia, but the complication of SB was observed in 30% of the participants, and SB events appeared immediately before or during the interictal period of the GE episodes in these cases.

Conclusions: Given the clinical background, posture- and sleep stage-dependent appearance of GEs, and the relatively high complication rate of SB, catathrenia pathogenesis may be heterogeneous or comprise elements of different sleep disorders.

catathrenia 的临床描述性变量和多导睡眠图检查结果的特征。
研究目的:卡他性睡眠呼吸暂停症在《国际睡眠障碍分类》第三版中被归类为睡眠相关呼吸障碍变异体,但其有效性仍未得到证实。我们分析了 Catathrenia 的临床描述性变量和多导睡眠图结果,并讨论了其与阻塞性睡眠呼吸暂停(OSA)、非快速眼动寄生虫和睡眠磨牙症(SB)的异同:我们对通过多导睡眠图诊断出的 47 名夜间呻吟患者进行了回顾性分析。我们研究了患者的性别、体重指数、发病年龄、每周症状出现频率以及是否存在合并症,其中包括 OSA、周期性肢体运动障碍、非 REM 辅助性失眠和 SB。根据睡眠姿势和睡眠阶段计算呻吟事件(GE)指数:结果:呻吟症患者的分布无性别差异(男性/女性=20:27),体重指数为(20.6±3.0)kg/m2,发病年龄为(18.2±7.4)岁。N1和R期的GE指数高于N3期,仰卧位高于侧卧位。没有并发非快速动眼期寄生虫性失眠的病例,但有30%的参与者出现了SB并发症,在这些病例中,SB事件紧接在GE发作前或发作间期出现:鉴于GE的临床背景、姿势和睡眠阶段依赖性以及相对较高的SB并发症发生率,白内障的发病机制可能是异质性的,或包含不同睡眠障碍的因素。
