1、CPAP治疗OSA前后血清瘦素及胃饥饿素变化临床观察作者:王实,陈雷,刘放,何微,鲁刚,夏书月【摘要】观察OSA患者在CPAP治疗前后血清瘦素和胃饥饿素的变化,评价CPAP对OSA患者瘦素及胃饥饿素的影响。方法:40例OSA患者均接受CPAP治疗。分别在治疗后1周、6个月来院测定PSG。坚持治疗者,6次/周,每晚治疗时间不少于5h为入选。观察期间BMI变化<1.5kg/m2,符合要求者18例;未符合要求者22例。设为对照组。两组分别于CPAP治疗前及后1周、6个月抽取空腹静脉血,测定瘦素、胃饥饿素、空腹血糖(FBG)、真胰岛素(TI)。瘦素和胃饥饿素的测定采用放
2、射免疫法。结果:CPAP治疗一周结果:18例OSAS患者应用CPAP平均压力为(10.8±2.6)cmH20,90%可信限压力为(12.59±1.3)cmH20oAHI从(59.82±7.87)次/h降至(6.58±0.83)次/h。最低SaO2%从60.8±3.9提高到94.86±0.663。血浆胃饥饿素、瘦素有所下降,但FBG和TI无明显变化。CPAP治疗6个月结果:18例OSAS患者其CPAP平均治疗压力为(9.89±1.86)cmH20,平均每天治疗的时间为(6.71±0.5)h,选用90%可信限压力值。患者体重BMI、NC、WHR治疗前后无明显变化。但
3、经CPAP治疗有效地改善睡眠呼吸紊乱及低氧状态,生活质量明显提高。胃饥饿素及瘦素水平在长期的治疗后明显下降。FBG和TI也在治疗后下降。22例对照组上述各项检查无变化。结论:OSA患者血清瘦素变化是由CPAP治疗而影响并独立于BMI。CPAP长期治疗可以改善OSA的糖代谢和胰岛素抵抗。OSA是导致胃饥饿素和瘦素代谢紊乱引起体重增加,导致肥胖原因之一。【关键词】胃饥饿素;阻塞性呼吸睡眠暂停(OSA);持续气道正压通气(CPAP)AbstractObjective:Toevaluatethechangeofghrelinandleptinlevelsinpatien
