为探讨肺结核在小儿反复呼吸道感染病因中所起的作用,本文对103例小儿反复呼吸道感染患儿进行了1:1配对病例对照研究,并对其中部分反复呼吸道感染并存肺结核的患儿进行了抗痨治疗后随访观察.结果表明,肺结核是反复呼吸道感染的高危因素,OR为5.57,OR95％CI为3.17～7.97,PAR％为34％。19例病儿抗痨治疗3月至18月后,11例痊愈,6例呼吸道感染次数明显减少.本结果提示肺结核是引起小儿反复呼吸道感染的重要病因之一.
In order to explore the role of tuberculosis in the etiology of recurrent respiratory tract infections in children, 103 cases of children with recurrent respiratory tract infection were studied in a 1: 1 matched case-control study, and some of the children with recurrent respiratory tract infection complicated with pulmonary tuberculosis After treatment, follow-up observation showed that tuberculosis was the risk factor of recurrent respiratory tract infection, OR was 5.57, OR95% CI was 3.17-7.97, PAR% was 34%. Nineteen patients with anti-tuberculosis treatment from March to 18 months, 11 patients recovered, 6 cases of respiratory tract infection was significantly reduced.The results suggest that tuberculosis is one of the important causes of recurrent respiratory tract infections in children.
