在结核病患病率低的多数国家,患有非活动性结核或纤维灶者定期到结核病或胸科门诊复查。但是,关于复发病人的发现方式的一些报告指出:大多数复发者不是由常规随诊查出的,约2/3系通过其他途径如胸部或别的症状而发现。为了阐明对非活动性结核或纤维灶患者进行每年胸部X线及痰或气管洗涤液细菌学检查的收益如何,特设计本研究,由荷兰Amsterdan(简称A地)Rotterdan(R地)及Utrecht(U地)的结核病门诊部负责,该3地各有居民约80万、70万及50万。凡年在15岁以上而有非活动性结核病或纤维病灶3年以上者为研究对象。
In most countries with a low prevalence of tuberculosis, patients with inactive tuberculosis or fibrosis are regularly referred for tuberculosis or thoracic clinic visits. However, some reports on the way recurrence patients find out indicate that most relapsers are not detected by regular follow-up and about two-thirds are found by other pathways such as chest or other symptoms. In order to elucidate the benefits of annual chest X-ray and bacteriological examination of sputum or tracheal washings in patients with active TB or fibrinolysis, this study was designed by Rotterdan (Netherlands) and Utrecht (Netherlands) U) TB clinics are responsible for the three places each have about 800,000 residents, 700,000 and 500,000. Where the age over 15 years of age and non-active tuberculosis or fibronectin for more than 3 years as the research object.
