    摘要:

    目的 探讨阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome, OSAHS)儿童血浆黏附分子水平的变化及意义。方法 选择2009年1月~2011年6月在新疆医科大学第一附属医院诊治的95例OSAHS患儿,并选取同期健康儿童46例作为对照。检测P-选择素(P-selectin)和细胞间黏附分子-1(ICAM-1),测定各组儿童身高、体重及多导睡眠监测(polysomnogram, PSG)。结果 重度OSAHS组的Pselectin浓度值为(127.2±56.3)ng/ml,中度OSAHS组为(91.5±37.8)ng/ml,轻度OSAHS组为(88.2±45.7)ng/ml;对照组为(54.5±30.3)ng/ml,4组比较差异具有统计学意义(F=4.26,P<0.05)。4组血浆ICAM1浓度值比较,差异无统计学意义(F=1.13,P>0.05),肥胖儿童的ICAM1浓度值高于非肥胖儿童[(223.4±46.4)ng/ml vs(137.2± 78.9)ng/ml],两组比较差异具有统计学意义(t=3.041,P<0.05);Pselection与呼吸暂停低通气指数(AHI)、呼吸觉醒指数(RAI)呈正相关(分别为r=0.28,P<0.05;r=0.19,P<0.05);与指脉氧饱和度(SpO2 nadir)呈负相关(r=-0.26,P<0.05)。结论 P-selection在轻、中、重度OSAHS患儿中升高,提示OSAHS能诱发炎性反应的产生,增加儿童患心血管疾患的危险性。ICAM1升高的因素主要归因于肥胖而非OSAHS。 

    Abstract:

    Objective To explore the changes of plasma levels of adhesion molecules in children with obstructive sleep apnea hypopnea syndrome (OSAHS) and the clinical significance. Methods Ninetyfive children with OSAHS in the First Affiliated Hospital of Xinjiang Medical University from Jan. 2009 to Jun. 2011 were selected for the study. Fortysix children were selected as healthy controls. Plasma levels of intercellular adhesion molecule (ICAM)1 and Pselectin were measured by enzymelinked immunosorbent assay. Height, weight were measured and body mass index (BMI) was calculated in these subjects. Polysomnography was performed. Results The Pselectin levels in the severe OSAHS group (127.2±56.3 ng/ml) and moderate OSAHS group (91.5±37.8 ng/ml) were significantly higher than that of the control group (54.5±30.3 ng/mL) (F=4.26, P<0.05). The differences of ICAM1 levels among abovementioned groups were statistically insignificant. However, the ICAM1 level of obese children (223.4±46.4 ng/ml) was significantly higher than that of nonobese ones (137.2±78.9 ng/ml) (t=3.041, P<0.05). Furthermore, the level of P-selectin was related positively with apnea hypopnea index (r=0.28, P<0.05), respiratory arousal index (r=0.19, P<0.05) and negatively with nadir of oxygen saturation as measured by pulse oximetry (r=-0.26, P<0.05). Conclusion Children with moderate to severe OSAHS have plasma elevations of Pselectin, a marker of platelet activation, suggesting that inflammatory processes may be elicited by OSAHS in children, and may contribute to accelerated risk for cardiovascular morbidity. In contrast, elevations in ICAM1 are primarily associated with obesity rather than OSAHS.
