摘要
目的:涂阳肺结核患者密切接触者活动性肺结核检出情况。方法:在接受检查的870例密切接触者中,年龄<15岁的儿童进行结核菌素纯蛋白衍生物试验,对结核菌素试验≥15mm或虽<15mm但伴有水疱的强反应者,和年龄≥15岁人群摄X线胸片,对X线胸片提示肺部有异常阴影者进行痰涂片检查。结果:涂阳肺结核患者密切接触者中活动性肺结核患者检出率为2.9%,涂阳肺结核检出率为0.5%;肺部病灶有空洞和排菌量大的患者的密切接触者活动性肺结核检出率高;密切接触者中年龄>60岁组其活动性肺结核的检出率高于其他组。结论:对涂阳肺结核患者的密切接触者进行筛查,有助于肺结核患者的发现,是肺结核病例发现的一种有效手段。
Objective： To investigate active pulmonary tuberculosis situation in exposed to patients with smear positive pulmonary tuberculosis. Methods：Among 870 close contacts, children younger than 15 years of age received Purified Protein Derivative of tuberculin skin test, X - ray was taken for children whose TST was more than 15 mm or less than 15mm with blister and people older than 15 years of age, sputum smear were taken for patients with abnormal lung shadow. Results： Of close contacts exposed to patients with smear positive, the detection rate of patients with active pulmonary tuberculosis and with smear positive were 2.9% and 0. 5%. The detection rate was high in close contacts exposed to patients with pulmonary cavity and high bacterial. The detection rate in group of contacts aged 60 years old was higher than others. Conclusions：It is helpful to discover TB case by screening in close contacts exposed to patients with smear positive. This is an effective means to find new case of pulmonary tuberculosis.
