ABSTRACT
<p><b>OBJECTIVE</b>Impulse oscillometry (IOS) is a novel technique for the evaluation of pulmonary function. Soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) are definitive indicators for the severity of asthma. This study aimed to explore the relationship of IOS pulmonary function with sICAM-1 and sVCAM-1, and their values in childhood asthma.</p><p><b>METHODS</b>IOS via Master Screen System for pulmonary function was performed in 40 children with acute asthma and 25 healthy children. Twenty-three of 40 children with acute asthma were re-tested for IOS pulmonary function at remission. sICAM-1 and sVCAM-1 levels were measured in 23 children with acute asthma, 20 asthmatic children at remission and 16 healthy children.</p><p><b>RESULTS</b>The parameters of IOS pulmonary function, R5, R20, R5-R20, X5, Fres and Zrs in children with acute asthma were significantly higher than in asthmatic children at remission and in normal controls (q= 2.91-15.61, P < 0.01 or 0.05). There were significant differences in R5, R5-R20, Fres and Zrs between the asthmatic children at remission and normal controls (q= 3.08- 9.19, P < 0.01 or 0.05). sICAM-1 and sVCAM-1 levels in children with acute asthma were significantly higher than in asthmatic children at remission and in normal controls (q= 6.23-26.15, P < 0.01). The asthmatic children at remission had higher levels of sICAM-1 and sVCAM-1 than the normal controls (q=16.86, 12.46, P < 0.01). R5-R20 positively correlated with sICAM-1 and sVCAM-1 in children with acute asthma (r=0.45, 0.57, P <0.05).</p><p><b>CONCLUSIONS</b>IOS for pulmonary function and sICAM-1 and sVCAM-1 may be used to evaluate the severity and therapeutic effects of childhood asthma. A correlation exists between IOS pulmonary function and sICAM-1 and sVCAM-1.</p>
