【摘 要】 目的 通过检测阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者经持续气道正压通气治疗前后的血清瘦素水平,以探究持续气道正压通气治疗对OSAHS患者血清瘦素的影响。 方法 选取30例OSAHS且行持续气道正压通气治疗的患者为观察组,32例同期健康体检患者为对照组。测定观察组患者持续正压通气治疗前后的血清瘦素水平,并与对照组进行比较。结果 OSAHS患者经持续气道正压通气治疗后,且治疗后血清瘦素含量较治疗前显著下降,差异具有统计学意义(P<0.05)。 结论 持续气道正压通气治疗可有效降低血清瘦素水平。

【Abstract】 Objective To provide reference for clinical treatment by exploring effect of continuous positive airway pressure on the serum leptin levels of patients with obstructive sleep apnea hypopnea syndrome (OSAHS), we detected the levels of patients with OSAHS. Methods Thirty patients with OSAHS and then treated with continuous positive airway pressure treatment were selected into the observation group, 32 healthy cases in the same period were selected as control group. Levels of serum leptin were detected between observation group and control group. Results After treated with continuous positive airway pressure, compared with control group, the serum leptin levels were significantly decreased(P<0.05). Conclusion Continuous positive airway pressure treatment can effectively reduce serum leptin levels and slow down the deterioration of OSAHS patients

阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome, OSAHS)是一种由各种原因导致的,患者睡眠状态下反复发生呼吸暂停和(或)低通气,可以引起如低氧血症、高碳酸血症、反复觉醒和睡眠结构紊乱[1]。越来越多的研究表明OSAHS是高血压、充血性心力衰竭、缺血性心脏病、卒中等疾病的重要独立危险因素 [2-3]。而持续正压通气(continuous positive airway pressure, CPAP)是治疗OSAHS的首选方法[4]。近期研究发现OSAHS血清瘦素水平在OSAHS患者呈明显增高的状态[5]。因此,本研究拟初步探讨持续正压通气治疗阻塞性睡眠呼吸暂停低通气综合征患者血清瘦素水平的变化情况,以期为临床治疗提供一定的参考依据。
1 资料与方法
1.1 病例选择
将我院2011年1月至2014年12月收治的30例初次住院的阻塞性睡眠呼吸暂停低通气综合征纳入观察组,并给予持续正压通气治疗;同时选取32例健康体检患者为对照组。OSAHS的诊断标准为[1]:(1)睡眠呼吸暂停,即睡眠中口鼻呼吸气流完全停止>10s;(2)低通气,即呼吸气流强度(幅度)较基础值降低>50%,并伴有血氧饱和度较基础值下降>4%;(3)呼吸暂停和低通气指数(apnea hypopnea index, AHI)≥5次/h。
1.2 观察指标:血清瘦素水平
抽取观察组患者治疗前后、对照组患者清晨空腹静脉血5ml,离心后取其上清,并采用日本生产的OLYMPUS AU5400全自动生化分析仪检测血清瘦素水平。
1.3 统计学方法
采用统计软件SPSS 17.0对数据进行分析,计量资料以均数±标准差表示,两组间比较采用两独立样本t检验,而观察组治疗前后比较则采用配对t检验。计数资料采用χ2检验,以P<0.05表示差异有统计学意义。
2 结果
2.1 一般情况比较
观察组患者30例,男16例,女14例,年龄范围为(46-67)岁,平均年龄为(54.5±5.86)岁;对照组患者32例,男16例,女16例,年龄范围为(43-69)岁,平均年龄为(55.2±5.81)岁。两组患者在性别、年龄、身高方面差异不具有统计学意义(P>0.05)。
2.2 血清瘦素水平比较如表1所示
3 讨论
阻塞性睡眠呼吸暂停低通气综合征(OSAS)是最常见的一种睡眠异常。本研究结果显示OSAHS患者的基础代谢情况如体重指数、呼吸紊乱指数及微觉醒指数较健康体检者明显偏高,而最低SaO2(%)较健康体检者明显偏低,而持续正压通气治疗后基础代谢情况显著改善,提示持续正压通气治疗是OSAHS患者的有效治疗策略之一。瘦素是由脂肪细胞分泌的一种蛋白质类激素,可作用于下丘脑的代谢调节中枢,发挥抑制食欲,抑制脂肪合成的作用,而血清瘦素水平升高与人体脂肪重量成正比,瘦素水平变化可致病态肥胖[6]。OSAHS患者往往过于肥胖,血清瘦素水平异常升高;此外OSAHS患者的交感神经系统持续兴奋,使儿茶酚胺分泌增多引起交感神经持续兴奋,使脂肪动员增加,血清瘦素含量调节紊乱[7]。本研究显示OSAHS患者血清瘦素水平较健康体检者异常升高,而持续正压通气治疗可能通过改善低氧血症,进而改善低氧血症所导致的神经内分泌系统调节异常,从而降低血清瘦素水平,可见血清瘦素水平有望成为评价OSAHS患者病情严重程度和病情控制疗效的指标之一。 综上可见,持续正压通气治疗可有效改善阻塞性睡眠呼吸暂停低通气综合征患者可降低患者的血清瘦素水平。此外,本研究仍存在一定的局限性,本文纳入样本量过小,未来可进一步扩大样本量研究OSAHS患者血清瘦素异常升高的确切机制及持续正压通气治疗可降低OSAHS患者血清瘦素的机制。
