摘  要:目的评价未经治疗的阻塞性睡眠呼吸暂停(OSA)对2型糖尿病患者反映胰岛功能的指标c肽的影响。方法60例2型糖尿病患者行多导睡眠图(PSG)检查,并抽血检测c肽。根据呼吸暂停-低通气指数(AHI)将受试者分为4组:无OSA组(AHI〈5)20例;轻度OSA组(5≤AHI〈15)21例;中度OSA组(15≤AHI〈30)12例;重度OSA组(AHI≥30)7例。结果校正了年龄、体重指数(BMI)、腰围、空腹血糖、空腹胰岛素、病程及PSG显示的总睡眠时间后,OSA严重程度与c肽水平存在相关性(F=5.16,P=0.009)。与无OSA组相比,轻度OSA组校正后的空腹C肽平均下降0.13nmol/L(F=3.78,P=0.032),中度OSA组校正后的空腹c肽平均下降0.18nmol/L(F=3.16,P=0.048),重度OSA组校正后的空腹c肽平均下降0.25nmol/L(F=5.32,P=0.001)。结论2型糖尿病患者胰岛功能下降与其合并OSA的严重程度相关。Objective To determine the impact of obstructive sleep apnea(OSA) on C-peptide,the major clinical indicator of islet function in patients with type 2 diabetes. Methods Polysomnography was performed and C-peptide was measured in 60 patients with type 2 diabetes. Four groups were separated according to apnea-hyponea index (AHI) :20 patients in group without OSA (AHI 〈 5 ) ,21 patients in mild OSA group ( 5≤AHI 〈 15 ), 12 patients in moderate OSA ( 15≤AHI 〈 30 ) group, 7 patients in severe OSA group (AHI≥30). Results Severity of OSA was associated with C-peptide,after adjusting age,body mass index( BMI ) , waist circumference, fasting plasma glucose, fasting insulin, years of diabetes and total sleep time. Compared with patients without OSA,the adjusted mean C-peptide decreased 0.13 nmo]/L( F = 3.78, P = 0. 032) in mild OSA group, 0.18 nmol/L ( F = 3.16, P = 0. 048 ) in moderate OSA group, and 0.25 nmol/L ( F = 5.32,P = 0.001 ) in severe OSA group. Conclusion In patients with type 2 diabetes, severity of OSA is associated with poorer islet function.
