Objective To investigate the value of five testing techniques in the clinical diagnosis of pneumoconiosis combined pulmonary tuberculosis,including sputum smear,Xpert Mycobacterium tuberculosis/rifampicin(Xpert MTB/RIF),identification of Mycobacterium species,sputum acid-fast bacilli culture and tuberculosis-interferon-gamma release assays(TB-IGRA).Methods Patients with pneumoconiosis combined with tuberculosis who were hospitalized in the First Hospital of Xiamen University from July 2016 to May 2021 were included in the study.The patients were divided into the pneumoconiosis group(156 cases)and pneumoconiosis combined with tuberculosis group(111 cases)according to whether the pneumoconiosis patients were combined with tuberculosis or not.The general data of the patients in the two groups were compared with respect to gender,age,and dust exposure time,and the results of sputum smears,Xpert MTB/RIF,identification of Mycobacterium species,sputum acid-fast bacilli culture and TB-IGRA were collected to analyze the differences and the diagnostic value in the five testing techniques of the positivity rates for patients who have pneumoconiosis combined with pulmonary tuberculosis.Results In the group with pneumoconiosis combined with tuberculosis,the positive detection rate of TB-IGRA was the highest(81.1%),which was higher than other 4 testing methods(P<0.01).Combined testing in pairs suggested that the testing method of Xpert MTB/RIF and TB-IGRA combination was the highest(96.4%),significantly higher than the other 9 combinations(P<0.01).Conclusions TB-IGRA has higher positive detection rate for patients with pneumoconiosis combined with tuberculosis,and diagnostic efficiency can be further improved by combining Xpert MTB/RIF assay testing,which is of great clinical diagnostic value for the early diagnosis of pneumoconiosis combined with tuberculosis.
脊柱结核是脊柱感染性疾病中最为常见的类型。本文综述了脊柱结核外科治疗的现状及最新进展。在早期治疗阶段,规范化的抗结核药物治疗能够有效缓解疼痛,改善患者生活质量。但对于中后期,特别是椎旁脓肿较大,椎体骨质破坏较大而导致脊柱不稳定的患者,手术治疗往往是必要且必需的辅助手段,手术可以最大限度清除病变的椎间盘、椎体和脓肿,也应该最大限度保留健康的骨质。其主要原则包括病灶彻底清除、脊髓充分减压、脊柱稳定性重建等步骤。在手术治疗中,一期前路手术作为经典入路已经得到广泛应用,而单纯后路手术治疗也逐渐受到重视。近年来,随着微创手术技术的发展,其在脊柱结核治疗中的应用越来越广泛。微创手术的优势在于术中创伤更小、恢复更快,为患者带来了更好的治疗体验和临床效果。然而,对于手术的选择,临床医师需要综合考虑患者的个体差异性、临床表现及特征、影像学资料和手术适应证等多种因素,以确定最合适的治疗方案。只有充分考虑各种治疗手段的优劣,采取个性化、综合性的治疗方案,才能更好地提高患者的生活质量和治疗效果。
Spinal tuberculosis is the most common types of infectious diseases affecting the spine.This article reviews the current status and progress of surgical treatment for spinal tuberculosis.In the early and initial stages,standardized anti-tuberculosis drug therapy can effectively alleviate pain and improve patients' quality of life.However,for more complex cases in the middle and late stages,surgical treatment is needed,including thorough lesion clearance,adequate spinal cord decompression,and reconstruction of spinal stability.In surgical treatment,anterior approach surgery,as a classical method,has been widely applied,and posterior approach surgery alone has gradually gained attention.In recent years,with the development of minimally invasive surgical techniques,their application in the treatment of spinal tuberculosis has become increasingly widespread.The advantages of minimally invasive surgery lie in smaller intraoperative trauma and faster recovery,providing patients with better treatment experience and clinical outcomes.However,for the selection of surgery,clinicians need to consider multiple factors such as individual differences,clinical manifestations and characteristics,imaging data and surgical indications to determine the most suitable treatment plan.Only by fully considering the advantages and disadvantages of various treatment modalities and adopting personalized,comprehensive treatment plans can the quality of life and treatment outcomes of patients be effectively improved.
目的 分析对比肺部受累的惠普尔病与初治菌阴肺结核患者的临床特征,提高对肺部受累的惠普尔病的认识、诊断及鉴别水平。方法 回顾性收集20例肺部受累的惠普尔病为病例组,并随机选取同期56例初治菌阴肺结核患者为对照组进行对比,探讨肺部受累的惠普尔病的临床特征。结果 病例组中老年(>37岁)、急性或亚急性的病程比例高于对照组(P<0.05)。CT影像学中,从病灶分布来看,病例组的病灶分布在下叶的病例比例高于对照组(P<0.05),病灶分布在上叶的病例比例低于对照组(P<0.05);从形态上看,病例组中表现为网状病灶、间质性肺炎的比例高于对照组(P<0.05),病例组中表现为空洞、纤维条索、实性影、结节影、树芽征、肺门淋巴结肿大的比例低于对照组(P<0.05),而性别、合并免疫力低下疾病、咳嗽、咳痰、发热、咳血、关节痛、腹泻等在组间比较差异均无统计学意义。病例组全部病例的肺泡灌洗液宏基因测序结果显示:惠普尔养障体是唯一菌19例(95.0%)或主要菌1例(5.00%,合并结核菌1序列),而对照组肺泡灌洗液宏基因测序结果显示:21例(37.5%)检测出结核分枝杆菌(TB)复合群是唯一菌或主要致病菌,18例TB-RNA(+),15例TB-LAMP(+)。结论 惠普尔病在临床可表现为急性或亚急性病程,好发中老年男性,以发热和(或)呼吸道症状为主,可伴或不伴有腹泻、关节痛;肺部影像学以下肺网状、间质性肺炎改变为主,可以单独累及肺部;与初治菌阴肺结核患者临床症状极其相似。应尽快完善支气管镜检查,肺泡灌洗液的宏基因检测对早期、快速诊断此病尤为重要。
Objective To analyze and compare the clinical features of patients with pulmonary involvement of Whipple disease and primary treated bacteriological negative pulmonary tuberculosis,so as to improve the recognition,diagnosis and differentiation ability of pulmonary involvement of Whipple disease.Methods Clinical features of Whipple disease with pulmonary involvement were investigated by retrospectively collecting 20 cases as a case group,comparing with 56 randomly selected patients with primary treated bacteriological negative pulmonary tuberculosis as a control group during the same period.Results The case group had a significantly higher proportion of older patients(>37 years),acute or subacute disease courses than the control group (P<0.05).On CT imaging,in terms of lesion distribution,the proportion of cases with lesions in the lower lobe was significantly more in the case group than in the control group(P<0.05),and the ratio of cases with lesions in the upper lobe was considerably less than in the control group(P<0.05).Regarding morphology,significantly more of the case group showed reticular lesions and interstitial pneumonia than the control group(P<0.05).Significantly fewer of the case group showed cavities,fibrous bands,solid shadows,nodular shadows,tree-bud signs,and enlarged hilar lymph nodes than the control group(P<0.05).No statistically significant differences existed between the two groups in gender,combined immunocompromising diseases,cough,sputum,fever,coughing up blood,arthralgia or diarrhea. At the same time,the differences of gender,combined immunocompromised disease,cough,sputum,fever,coughing up blood,arthralgia,and diarrhea were not statistically significant.The metagenomic sequencing of alveolar lavage fluid in the case group revealed Tropheryma whipplei as the sole pathogenic bacteria in 19 cases(95%)or the primary pathogenic bacteria in 1 case(5.00%,combined TB 1 sequence).In contrast,metagenomic sequencing of alveolar lavage fluid in the control group detected Mycobacterium tuberculosis complex as the sole or primary pathogenic bacteria in 21 cases(37.5%),TB-RNA(+)in 18 cases and TB-LAMP(+)in 15 cases.Conclusions Clinical presentation in Whipple disease can be of an acute or subacute course,preferably in middle-aged and older men,with fever or/and respiratory symptoms,either with or without diarrhea and arthralgia.Its pulmonary imaging dominates with reticular,interstitial pneumonia changes in the lower lungs,which can involve the lungs alone in the disease.At the same time,the clinical symptoms are highly similar to those patients with primary treated bacteriological negative pulmonary tuberculosis.Therefore,it is vital to complete bronchoscopy and metagenomic sequencing of alveolar lavage fluid as soon as possible for early and rapid diagnosis of this Whipple disease.Treatment with sensitive antibacterial drugs can result in significant improvement and save patients' lives.

Objective To investigate the changes in the diversity and abundance of intestinal flora during the intensive period of anti-tuberculosis treatment. Methods Stool specimens from 20 patients with newly treated bacteria-positive pulmonary tuberculosis in Guangzhou Chest Hospital, which were treated with the intensive treatment for 1 week and whole intensive treatment, were collected. All the specimens were subjected to 16S rDNA sequencing and bioinformatics analysis. Results The Alpha diversity index Chao1 and observed_otus index of the treatment group with whole process were (97.8±28.3) and (97.6±28.2) respectively, which were higher than (81±34.7) and (81±34.7) of the 1-week treatment group, which had statistical differences (P=0.04;P=0.038). PCoA analysis based on weighted and unweighted Unifrac distance showed that there was no significant difference in the overall flora community structure between the two groups. Among the bacteria families with higher relative abundance, the relative abundance of Bacteroidaceae,Enterococcaceae,Enterobacteriaceae,Erysipelotrichaceae,Porphyromonadaceae and Bifidobacteriaceae in the treatment group with whole process decreased, the relative abundance content of Lachnodoiraceae,Fusobacteriaceae,Prevotellaceae, Rumincoccaceae, and Veillonellaceae increased. By using linear discriminant analysis effect size (LEfse) to analyze the two sets of data, it was found that at the genus level,Rumincoccaceae of Firmicutes and Lactobacillus;Collinsella of Actinobacteria were significantly different species between the groups. Conclusion Compared with 1 week of treatment, the diversity of intestinal flora increased at the end of intensive treatment, but there was no significant difference in the community structure of intestinal flora. The abundance of intestinal Bacteroidaceae decreased, and the abundance of Lachnodoiraceae increased.
目的 探索两种常用免疫学指标—结核菌素试验(purified protein derivative skin test, PPD皮试)与结核分枝杆菌γ-干扰素释放试验(tuberculosis-interferon gamma release assay,TB-IGRA)对结核病的辅助诊断价值。方法 收集2017年1月—2021年1月于我中心门诊部就诊的疑似结核病患者资料,共171例,所有病例均行PPD皮试和外周血TB-IGRA。将病例分为结核病组(TB组)和非结核病组(非TB组)。TB组共98例,非TB组共73例。比较两组病例PPD皮试、TB-IGRA对结核病诊断的准确度、敏感度、特异度。结果 TB-IGRA对结核病诊断的准确度、敏感度和特异度分别为94.2%、93.9%和90.4%,PPD皮试对结核病诊断的准确度、敏感度和特异度分别为77.2%、84.7%和76.7%。TB-IGRA的准确度和特异度与PPD皮试比较差异有统计学意义(分别为χ2=20.034,P<0.05和χ2=5.176,P<0.05);TB-IGRA的敏感度高于PPD皮试,但两者比较差异无统计学意义(χ2=0.948,P>0.05)。2组间TB-IGRA结果、PPD皮试结果比较差异均具有统计学意义(分别为χ2=132.77,P<0.01和χ2=47.963 5,P<0.01)。结论 TB-IGRA和PPD皮试均具有良好的结核病辅助诊断价值;TB-IGRA的引进大大提高了诊断试验的准确度和特异度,但仍需要进一步探索其诊断标准以更好地为临床使用。
Objective To explore the auxiliary diagnosis value of two commonly used immunological indicators for tuberculosis, purified protein derivative skin test (PPD test) and tuberculosis-interferon gamma release assay (TB-IGRA). Methods A total of 171 cases of suspected tuberculosis patients who were treated in the outpatient department of our center from January 2017 to January 2021 were collected. All cases underwent PPD test and peripheral blood TB-IGRA. The cases were divided into tuberculosis groups (TB group) and non-tuberculosis group (non-TB group). There were 98 cases in the TB group and 73 cases in the non-TB group. The accuracy, sensitivity, and specificity of PPD test and TB-IGRA for tuberculosis diagnosis were compared between the two groups. Results The accuracy, sensitivity, and specificity of TB-IGRA for tuberculosis diagnosis were 94.2%, 93.9% and 90.4% respectively, which of PPD test for tuberculosis diagnosis were 77.2%, 84.7% and 76.7% respectively. The accuracy and specificity of TB-IGRA were statistically different from those of PPD test (χ2=20.034,P<0.05 and χ2=5.176,P<0.05, respectively). The sensitivity of TB-IGRA was higher than that of PPD test, but the difference was not statistically significant (χ2=0.948,P>0.05). The differences of TB-IGRA and PPD test results between the two groups were statistically significant (χ2=132.77,P<0.01 and χ2=47.9635,P<0.01). Conclusion Both TB-IGRA and PPD test had good auxiliary diagnostic value for tuberculosis; the introduction of TB-IGRA had greatly improved the accuracy and specificity of the diagnostic test, but it is still necessary to further explore its diagnostic criteria to better serve the clinical use.
