目的总结出入境人员中耐多药肺结核(MDR-TB)患者胸部X线影像学特征,有助于基层体检机构及时发现MDR-TB。方法将2012年1月-2016年5月广东国际旅行卫生保健中心诊断的72例MDR-TB患者纳入MDR-TB组,并按性别、年龄、职业、户籍及病程进行个体匹配,纳入同样数量的非MDR-TB患者作为对照组,比较两组患者X线胸片的影像学特征。结果相对于对照组,MDR-TB组发生双肺中下野病变的患者明显增多,出现斑点状影、空洞和肺内播散的机会大(P<0.05)。结论 MDR-TB患者胸部X线影像学多在双肺中下野出现改变,并以斑点状影、空洞和肺内播散最具有特异性。
OBJECTIVE: To summarize the chest X-ray findings of MDR-TB patients in entry countries and to facilitate the timely detection of MDR-TB by primary health care institutions. Methods 72 patients with MDR-TB diagnosed by Guangdong International Travel Health Care Center from January 2012 to May 2016 were enrolled in the MDR-TB group. Individuals were matched by sex, age, occupation, household registration and duration of disease, and the same number of Non-MDR-TB patients served as a control group, and radiographic characteristics of the two groups were compared. Results Compared with the control group, patients with MDR-TB group had significantly increased bilateral middle and lower lung pathological changes. The chances of speckling, voids and lung dissemination were higher (P <0.05). Conclusions Chest X-ray images of MDR-TB patients mostly change in the middle and lower lungs of the lungs. Speckle speckles, voids and lung dissemination are most specific.
