小儿哮喘病与卡介苗疤痕的相关性研究

The relationship between asthma and BCG scar size in children

目的研究卡介苗疤痕（卡疤）与哮喘的相关性。方法观察200例儿童，年龄6—12岁，其中哮喘患儿100例，正常对照100例，测量卡疤纵横直径，取平均值。结果哮喘患儿中卡疤直径大于5mm者有52例，占52％。正常对照组卡疤直径大于5mm者有72例，占72％，两组相比较，差别有显著性。两组儿童在年龄分布和性别构成上差异无显著性。结论卡疤直径可能是哮喘发作的一个有价值的预报因子。

Objective To investigate the relationship between asthma and BCG Scar Size in children. Methods 200 children aged from 6 to 12 years participated in the study. 100 with asthma and 100 normal controls. The BCG scar was measured as the average of the transverse and longitudinal diameters. Results The data showed that 52% （52/100） of the children with asthma had scars larger than 5 mm but that 72% （72/100） of the nonasthmatic control children had scars larger than 5 mm （P 〈 0.05 ）. There was no difference between both groups regarding age and gender. Conclusion BCG Scar Size is a useful marker for Asthma in children.
