目的:探讨阻塞性睡眠呼吸暂停低通气综合征( OSAHS)患者血清炎症指标和认知功能的相关性及持续气道正压通气( CPAP)的疗效。方法纳入自2011年6月至2013年4月在苏州大学附属第二医院睡眠中心行多导睡眠图( PSG)监测并符合本研究入组标准的患者139例,根据呼吸暂停低通气指数( AHI)分为单纯鼾症组18例,轻度OSAHS组23例,中度OSAHS组29例,重度OSAHS组69例。利用蒙特利尔认知评估量表(MoCA)、简易精神状态检查量表(MMSE),Epworth嗜睡量表(ESS)评估认知功能及日间嗜睡程度,检测血清中超敏C反应蛋白(Hs-CRP)、肿瘤坏死因子-α( TNF-α)、瘦素的水平,分析各组患者认知功能评分、血清炎症指标及PSG参数之间的差异及相关性。分析33例接受长期家庭CPAP治疗的重度OSAHS患者(治疗组)治疗前后有关指标的变化。结果重度 OSAHS 组血清 Hs-CRP、TNF-α、瘦素水平分别为(1.77±1.19) mg/L、(21.04±7.78)pmol/L、(15.21±13.26)mmol/L,均显著高于单纯鼾症组的(0.92±0.82)mg/L、(10.30±5.23) pmol/L、(6.35±4.51) mmol/L( P<0.05);校正了年龄、体质指数( BMI)和受教育年限后,MoCA评分与血清TNF-α水平、AHI、氧减指数( ODI )、血氧饱和度<90%的时间比率( TS90%)呈负相关(r=-0.266、-0.236、-0.201、-0.180),与血氧饱和度夜间最低值(LSaO2)呈正相关(r=0.224)(均P<0.05),认知功能损伤主要表现在视空间与执行力、注意及延迟回忆。治疗组治疗时间>6个月,依从性良好,治疗后患者血清中Hs-CRP、TNF-α和瘦素水平分别为(1.20±0.88)mg/L,(14.12±4.34)pmol/L及(7.37±5.30) mmol/L,较治疗前的(2.03±1.58) mg/L,(22.74±6.72) pmol/L 及(13.69±7.17)mmol/L均显著降低,MoCA评分(27.79±1.69)及ESS评分(4.33±3.14)较治疗前(24.76±2.57)及(12.61±5.80)改善(均P<0.01),MoCA量表各子项评分均较治疗前有所改善。结论 OSAHS患者存在认知功能障碍及炎症反应增高,认知功能与血清TNF-α水平及夜间间歇低氧相关,提示炎症反应参与间歇低氧诱导的认知功能障碍的发生;长期CPAP治疗可减轻OSAHS患者血清炎症反应,并改善认知功能损伤。

Objective To explore the association between serum inflammation levels and cognitive function in patients with obstructive sleep apnea-hypopnea syndromes ( OSAHS) and evaluate the effects of continuous positive airway pressure treatment ( CPAP) on serum inflammation levels and cognitive function . Methods A total of 139 eligible patients were monitored by overnight polysomnography ( PSG) at Sleep Center, Second Affiliated Hospital , Soochow University from June 2011 to April 2013.Based on the results of apnea-hypopnea index (AHI), they were divided into 4 groups of primary snoring (n=18), mild OSAHS ( n =23 ) , moderate OSAHS ( n =29 ) and severe OSAHS ( n =69 ) .The questionnaires of Montreal Cognitive Assessment ( MoCA ) , Mini-Mental State Examination ( MMSE ) and Epworth Sleepiness Scale ( ESS ) were administered to assess cognitive function and daytime sleepiness .The serum levels of high-sensitivity C-reactive protein ( Hs-CRP) , leptin and tumor necrosis factor alpha ( TNF-α) were detected to evaluate systemic inflammation.The questionnaire scores , serum levels of Hs-CRP, leptin and TNF-αand PSG parameters were compared among 4 groups.Thirty-three patients in severe OSAHS group ( treatment group) with good adherence were evaluated at baseline and after long-time CPAP treatment. Results Compared to primary snoring group, the serum Hs-CRP ((1.77 ±1.19) vs (0.92 ±0.82) mg/L), leptin ((15.21 ±13.26) vs (6.35 ±4.51) mmol/L) and TNF-α((21.04 ±7.78) vs (10.30 ±5.23) pmol/L) levels increased significantly in severe OSAHS group ( P <0.05 ) .After adjusting for body mass index ( BMI ) , age and education years , MoCA scores showed negative correlations with serum TNF-α, AHI, oxygen reduction index ( ODI) and TS90% ( r=-0.266, -0.236, -0.201, -0.18 respectively, all P<0.05) and positive correlations with minimum oxygen saturation (LSaO2)(r=0.224, P<0.05).The evaluations of MoCA subdomains further revealed selective reductions in visual space , executive function , attention and delayed memory function .The treatment group with good adherence to >6-month continuous positive airway pressure ( CPAP) treatment and after CPAP treatment , the serum levels of Hs-CRP, TNF-αand leptin improved markedly ( ( 1.20 ±0.88 ) vs ( 2.03 ±1.58 ) mg/L, ( 14.12 ±4.34 ) vs ( 22.74 ± 6.72) pmol/L and (7.37 ±5.30) vs (13.69 ±7.17) mmol/L respectively).The scores of MoCA and ESS also improved (27.79 ±1.69 vs 24.76 ±2.57, 4.33 ±3.14 vs 12.61 ±5.80 respectively) (all P<0.01). The score of all MoCA subdomains improved after treatment .Conclusions Cognitive dysfunction and inflammatory reaction are common in OSAHS patients .MoCA scores are correlated significantly with serum level of TNF-αand nocturnal intermittent hypoxia .Systemic inflammation may play an important role in cognitive dysfunction of OSAHS patients .And long-time CPAP treatment can improve systemic inflammatory response and cognitive impairment .
