持续正压通气治疗对阻塞性睡眠呼吸暂停低通气综合征患者血清白细胞介素-23及C反应蛋白的影响

Effect of continuous positive airway pressure therapy on serum IL-23 and CRP levels in patients with obstructive sleep apnea hypopnea syndrome

目的通过检测阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者应用持续气道正压通气(CPAP治疗前后血清白细胞介素-23(IL-23)及C反应蛋白(CRP)浓度的变化,探讨OSAHS患者的发病机制及治疗。方法选择经多导睡眠图确诊为中重度OSAHS的58例患者为试验组,选择匹配试验组患者年龄、性别及体重指数的门诊健康体检者57例为对照组。检测对照组血清IL-23及CRP浓度水平,检测试验组应用呼吸机前及应用CPAP 3个月后血清IL-23及CRP浓度。结果 OSAHS患者CPAP治疗前血清IL-23及CRP浓度水平高于对照组,差异有统计学意义(均P<0.05)。OSAHS患者应用CPAP治疗3个月后的血清IL-23及CRP浓度水平显著低于应用CPAP前(均P<0.05)。OSAHS患者血清IL-23及CRP浓度与呼吸暂停低通气指数呈正相关(r值分别为0.756、0.345,均P<0.05),与平均氧饱和度呈负相关(r值分别为–0.715、–0.334,均P<0.05)。结论血清IL-23及CRP水平与OSAHS的严重程度呈正相关,经CPAP治疗后IL-23及CRP水平下降,提示CPAP可能通过降低OSAHS患者的炎症反应进而纠正缺氧,从而发挥治疗作用。

Objective To investigate the pathogenesis and treatment of obstructive sleep apnea hypopnea syndrome(OSAHS) by detecting the changes of serum interleukin-23(IL-23) and C-reactive protein(CRP) levels of the OSAHS patients before and after treatment with continuous positive airway pressure(CPAP). Methods Fifty-eight patients with moderate to severe OSAHS diagnosed by polysomnography were recruited as an experimental group,57 out-patient healthy subjects with matched age, sex and body mass index of the experimental group were enrolled as a control group. The serum concentrations of IL-23 and CRP in the experimental group were detected and compared before and after CPAP application for 3 months. The serum concentrations of IL-23 and CRP in the control group were also measured. Results The serum levels of IL-23 and CRP in the OSAHS patients were significantly higher than those in the normal control subjects(P<0.05). The serum levels of IL-23 and CRP in the OSAHS patients after CPAP treatment were significantly lower than those before CPAP treatment(P<0.05). The serum concentrations of IL-23 and CRP were positively correlated with apnea hypopnea index(r=0.756, r=0.345, P<0.05, respectively), and negatively correlated with mean oxygen saturation(r=–0.715, r=–0.334, P<0.05, respectively). Conclusions The serum levels of IL-23 and CRP are positively correlated with the severity of OSAHS. After CPAP treatment, the levels of IL-23 and CRP decrease, which indicates that CPAP treatment may reduce the inflammatory reaction and correct anoxia of OSAHS patients.
