福州城镇男性阻塞性睡眠呼吸暂停低通气综合征患者睾酮水平研究

目的 研究福州城镇男性阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者的血清睾酮水平及经鼻持续气道正压通气(nCPAP)治疗对OSAHS患者血清睾酮水平的影响.方法 182例入选者经多导睡眠监测,按年龄分25～45岁、46～65岁两层,再按睡眠呼吸紊乱严重程度进行分组:分别为正常对照组(20例、21例)、单纯性鼾症组(14例、13例)、轻度OSAHS组(21例、17例)、中度OSAHS组(19例、19例)、重度OSAHS组(18例、20例).在多导睡眠监测次晨抽取外周静脉血用电化学发光法测定血清睾酮.对比正常对照组、单纯性鼾症组、OSAHS组间睾酮水平的差异,分析睾酮水平与睡眠呼吸紊乱指数(AHI)、体质量指数(BMI)之间的相关性.开展nCPAP干预实验,对接受/未接受nCPAP治疗的中重度OSANS患者随访3个月,复查多导睡眠监测及血清睾酮指标.结果 ①正常对照组与单纯性鼾症组2组间血清睾酮差异无统计学意义(P值均＞0.05).OSAHS组血清睾酮较正常对照组及单纯性鼾症组低.②睾酮与AHI、BMI、年龄均呈负相关(r=-0.589,P＜0.01;r=-0.225;P＜0.05;r=-0.454,P＜0.01),睾酮与最低SaO2呈正相关(r=0.459,P＜0.01).③中重度OSAHS患者中,接受nCPAP治疗者随访3个月后,血清睾酮水平升高(P＜0.01).未接受nCPAP治疗者随访3个月后,血清睾酮水平无明显变化(P＞0.05).结论 ①OSAHS患者血清睾酮水平低,血清睾酮水平与AHI、BMI呈负相关.②OSAHS患者血清睾酮水平随年龄增加而降低.③nCPAP治疗可改善OSAHS患者血清睾酮水平.

Abstract：

Objective To explore the testosterone levels in Fuzhou urban male patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and impact of nasal continuous positive airway pressure (nCPAP) treatment. Methods Following polysomnographic examination, 182 sbjucts were assigned to 25-45years and 46-65years two groups. Each group consist of:control group(20,21 case), simple snores(14,13case), mild OSAHS(21,17case) ,moderate OSAHS(19,19 case),and severe OSAHS (18,20case). The serum level of testosterone was measured after sleep at the polysomnographic examination night. Of 76 patients with moderate or severe OSAHS, 29 patients who underwent nCPAP therapy were set as "nCPAP group" ,47 patients who did not undergo nCPAP therapy were set as "control group". 10 patients were excluded from further follow-up. The assessment protocol was then repeated after 3 months follow-up. Results ①There were no statistically significant differences of the serum level of testosterone between simple snores and control group. The serum level of testosterone was significantly lower in OSAHS patient. ② Liner regression analysis showed the serum level of testosterone was negatively correlated with AHI, BMI, year( r = -0.589, P ＜0. 01; r = -0.225, P ＜0.05; r = - 0.454, P＜0. 01), testosterone was correlated with SaO2 ( r =0.459, P ＜0.01). ③After 3 months nCPAP therapy in OSAHS patients, the serum level of testosterone was significantly increased ( P ＜ 0.01). While there were no similar changes in OSAHS patients without nCPAP therapy( P >0. 05). Conclusions ①OSAHS patients have lower level of testosterone. The serum level of testosterone was negatively correlated with AHI,BMI. ②As the age older,the serum level of testosterone lower in OSAHS patients. ③The serum level of testosterone could be improved by nCPAP therapy in OSAHS patients.
