ABSTRACT
OBJECTIVE:
Obstructive sleep apnea-hypopnea syndrome (OSAHS) may cause serious morbidities, such as systemic hypertension, diabetes, and cor pulmonale. However, currently no many reports on study of OSAHS in children are available. This study aimed to explore the effects of OSAHS on children's multiple systems.METHOD:
A total of 89 cases of children who came to the Sleep Treatment Center in the authors' hospital from March 2009 to December 2010 with snoring were tested with overnight polysomnography (PSG). They were classified into mild OSAHS group (n = 59, mean age of 5.71, SD = 2.46) and moderate to severe group (n = 30, mean age of 5.30, SD = 2.73) based on the PSG results, and 100 healthy children were selected as the control group (n = 100, mean age of 6 years, SD = 2.98). Data including height, weight, body mass index and blood pressure, peripheral blood routine, blood lipids, glucose and insulin, electrocardiogram and echocardiography were collected. Patients' adenoid face and abnormal occlusion were also recorded. Comparisons of the data were made among those groups.RESULT:
Mild OSAHS and moderate to severe group had significantly higher prevalence of adenoid face (23.7%, 26.7%), and abnormal occlusion (74.6%, 60.0%) than that in control group (0, 40%) (P < 0.05). There were no significant differences in terms of BMI between the OSAHS group and the control group, but the weight (kg) and height (cm) in the mild OSAHS group (23.3 ± 10.1, 114.9 ± 16.2) and moderate to severe group (21.9 ± 8.4, 110.8 ± 13.3) were lower than those of the control group (31.8 ± 10.1, 136.1 ± 15.1) (all P < 0.05). Compared with the control group, the level of HDL-C (mmol/L)and insulin (mU/L) in moderate and severe group decreased [(1.20 ± 0.30) vs. (1.40 ± 0.27), 2.79 (0.84 - 16.16) vs. 4.92 (0.76 - 16.80), P < 0.05], while the LDL-C (mmol/L) increased [(2.61 ± 0.75) vs. (2.32 ± 0.62), P < 0.05]. The red blood cell counts (× 10(12)/L) and the blood platelet counts (× 10(9)/L) in the mild OSAHS (4.93 ± 0.37, 292.92 ± 75.64) and moderate and severe OSAHS group (5.23 ± 0.22, 292.50 ± 63.05) were significantly higher in contrast to the control group (4.70 ± 0.31, 255.60 ± 69.12) (all P < 0.05), systolic blood pressure (mmHg) in mild group (98.54 ± 10.44) and moderate to severe group (99.13 ± 19.13) was significantly higher compared to control group (87.88 ± 11.37), and the heart rate (beats/min) in moderate to severe group (94.43 ± 10.64) was higher than those in control group (87.12 ± 16.20) (all P < 0.05). The mild OSAHS and moderate and severe OSAHS group had decreased right ventricular internal diameter [(14.24 ± 1.64) mm, (13.17 ± 2.07) mm ], increased main pulmonary artery diameter [(17.05 ± 3.33) mm, (16.33 ± 3.14) mm] and the thickness of right ventricular wall [(3.43 ± 0.26) mm, (3.57 ± 0.20) mm] compared to control group [ (16.10 ± 2.96) mm, (14.11 ± 2.52) mm, (3.32 ± 0.25) mm] (all P < 0.05).CONCLUSION:
OSAHS in children may be associated with craniofacial malformations, and may contribute to slow growth and development, elevated blood viscosity and blood pressure, metabolic abnormalities, and change cardiac structure.
