摘要
研究目的重叠综合征（OS）是阻塞性睡眠呼吸暂停低通气综合征（OSAHS）和慢性阻塞性肺疾病（COPD）两种常见疾病并存的综合征，本研究旨在探讨间歇性低氧血症和气流受限在多大程度上导致了重叠综合征患者的认知功能障碍：我们对 OSAHS、COPD 或 OS 患者与正常对照组进行了横断面研究，以确定 OSAHS、COPD 或 OS 患者的睡眠呼吸暂停/肺功能相关指标与认知功能障碍之间的关联：结果：共招募了 157 名参与者。与 COPD 组相比，OSAHS 和 OS 的调整后蒙特利尔认知评估（MoCA）得分均较低。此外，与对照组相比，慢性阻塞性肺病组的MoCA得分明显较低。认知障碍的发生率在 OSAHS 组为 57.4%，在 OS 组为 78%，明显高于 COPD 组（29%）和对照组（8.8%）。此外，与 OSAHS 组相比，OS 组受影响的认知领域范围更广。在 OSAHS 和 OS 组中，氧饱和度指数（ODI）和/或呼吸暂停低通气指数（AHI）的升高与埃普沃思睡眠量表（ESS）的升高呈正相关。强迫生命容量（FVC）、1 秒内强迫呼气容积（FEV1）和呼气峰流速（PEF）与 OSAHS 的认知评分呈正相关，但与 OS 的认知评分无关。OS患者血清中的低氧诱导因子-1α（HIF-1α）水平明显更高。逻辑回归发现，ODI是OS患者认知障碍的独立风险因素，而打鼾严重程度和PEF则是OSAHS的独立风险因素：讨论：本研究显示，OS、OSAHS 和 COPD 均存在明显的认知障碍。OS患者的睡眠相关指标可用于认知障碍的检测、鉴别和分级，而OSAHS患者的肺功能可用于认知障碍的检测和早期干预。
Evaluation of nocturnal apnea and airflow limitation as indicators for cognitive dysfunction in patients with chronic obstructive pulmonary disease/obstructive sleep apnea hypopnea syndrome overlap syndrome.
Objective: The aim of this study is to investigate how much intermittent hypoxemia and airflow limitation contribute to cognitive impairment in overlap syndrome (OS), which is the coexistence of two common diseases, obstructive sleep apnea hypopnea syndrome (OSAHS) and chronic obstructive pulmonary disease (COPD).
Methods: We conducted a cross-sectional study of patients with OSAHS, COPD or OS, compared with normal controls, to determine the association between sleep apnea/pulmonary function-related indicators and cognitive dysfunction in individuals with OSAHS, COPD or OS.
Results: A total of 157 participants were recruited. Both OSAHS and OS presented lower adjusted Montreal cognitive assessment (MoCA) scores compared with COPD group. In addition, the MoCA score was significantly lower in COPD group compared with control group. The incidence of cognitive impairment was 57.4% in OSAHS group, and 78% in OS group, which were significantly higher than COPD group (29%) and control group (8.8%). Furthermore, a broader range of cognitive domains were affected in OS group compared with OSAHS group. Elevated levels of oxygen desaturation index (ODI) and/or apnea hypopnea index (AHI) were positively correlated with increased Epworth sleeping scale (ESS) in OSAHS and OS. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and peak expiratory flow (PEF) were positively correlated with cognitive scores in OSAHS but not in OS. Serum level of hypoxia-inducible factor-1α (HIF-1α) was significantly higher in OS. Logistic regression identified ODI as an independent risk factor for cognitive impairment in OS, while severity of snoring and PEF were independent risk factors in OSAHS.
Discussion: This study revealed significant cognitive impairment in OS, OSAHS and COPD. Sleep-related indicators are warranted in OS patients for detection, differentiation and grading of cognitive impairment, whereas pulmonary functions are warranted in OSAHS patients for detection and early intervention of cognitive impairment.
