BACKGROUND:The common diagnostic methods for tuberculosis have been showing reduced sensitivity among chronic obstructive pulmonary disease patients. This study was conducted to evaluate and analyse the diagnostic value of an interferon-γ release assay in COPD patients complicated with pulmonary tuberculosis. METHODS:A nested case-control study was conducted on 123 COPD patients hospitalized at the Fifth Hospital of Shijiazhuang, Hebei Province, from January 2019 to June 2021. Thirty-one patients with active pulmonary tuberculosis complicated with COPD composed the observation group (Group A), 31 patients with nonactive pulmonary tuberculosis complicated with COPD composed the COPD control group (Group B), and 31 patients with active pulmonary tuberculosis not complicated with COPD composed the non-COPD control group (Group C). An interferon-γ release assay, a purified protein derivative of tuberculin (PPD) test, an anti-tuberculosis antibody test, a test of Mycobacterium tuberculosis by sputum smear microscopy and a test of Mycobacterium tuberculosis by PCR method were used to test patients in each group. The positive detection rates generated from the five test methods were compared and analysed. RESULTS:In COPD patients complicated with active pulmonary tuberculosis, the differences in the percentage of patients with positive interferon-γ release between the PPD test, anti-tuberculosis antibody test, Mycobacterium tuberculosis by sputum smear microscopy and PCR test results were statistically significant. CONCLUSION:In patients with COPD complicated with active pulmonary tuberculosis, the percentage of patients who were positive according to the interferon-γ release assay was higher than that according to the sputum smear microscopy, PCR detection of Mycobacterium tuberculosis in sputum specimen, and detection of anti-tuberculosis antibodies. COPD-related complications did not affect the T-SPOT; the greater the T-SPOT value was, the greater the likelihood of active TB. For patients who are T-SPOT positive but clinically considered to have inactive tuberculosis, regular follow-ups should be performed to observe changes in the patient's condition.
Abstract Background The diagnosis of tuberculous pleurisy (TP) presents a significant challenge due to the low bacterial load in pleural effusion (PE) samples. Cell-free Mycobacterium tuberculosis DNA (cf-TB) in PE samples is considered an optimal biomarker for diagnosing TP. This study aimed to evaluate the applicability of cf-TB testing across diverse research sites with a relatively large sample size. Methods Patients suspected of TP and presenting with clinical symptoms and radiological evidence of PE were consecutively enrolled by treating physicians from 11 research sites across 6 provinces in China between April 2020 and August 2022. Following centrifugation, sediments obtained from PE were used for Xpert MTB/RIF (Xpert) and mycobacterial culture, while the supernatants were subjected to cf-TB testing. This study employed a composite reference standard to definite TP, which was characterized by any positive result for Mycobacterium tuberculosis (MTB) through either PE culture, PE Xpert, or pleural biopsy. Results A total of 1412 participants underwent screening, and 1344 (95.2%) were subsequently enrolled in this study. Data from 1241 (92.3%) participants were included, comprising 284 with definite TP, 677 with clinically diagnosed TP, and 280 without TP. The sensitivity of cf-TB testing in definite TP was 73.6% (95% CI 68.2–78.4), significantly higher than both Xpert (40.8%, 95% CI 35.3–46.7, P < 0.001) and mycobacterial culture (54.2%, 95% CI 48.4–59.9, P < 0.001). When clinically diagnosed TP was incorporated into the composite reference standard for sensitivity analysis, cf-TB testing showed a sensitivity of 46.8% (450/961, 95% CI 43.7–50.0), significantly higher than both Xpert (116/961, 12.1%, 95% CI 10.2–14.3, P < 0.001) and mycobacterial culture (154/961, 16.0%, 95% CI 13.8–18.5, P < 0.001). The specificities of cf-TB testing, Xpert, and mycobacterial culture were all 100.0%. Conclusions The performance of cf-TB testing is significantly superior to that of Xpert and mycobacterial culture methods, indicating that it can be considered as the primary diagnostic approach for improving TP detection.

Objective To explore the risk factors of pulmonary tuberculosis in patients with chronic obstructive pulmonary disease(COPD) and establish a risk prediction model. Methods COPD patients in our hospital from January 2019 to December 2021were into case group(COPD patients with pulmonary tuberculosis) and control group(COPD patients) according to whether they had pulmonary tuberculosis or not, 40 patients in the case group and 40 patients in the control group were included by 1:1 propensity score matching method, to screen independent predictors of pulmonary tuberculosis in patients with COPD and to construct a risk prediction model. Results Age ≥ 70 years(OR=1.518, 95%CI: 1.230 ~ 2.262), smoking(OR=1.863, 95%CI: 1.461 ~ 2.741), long-term steroid use( > 3 months)(OR=4.314, 95%CI: 3.377 ~ 17.808) and COPD course ≥ 10 years(OR=3.031, 95%CI: 2.932 ~ 8.268)were independent risk factors for COPD complicated with pulmonary tuberculosis(P <0.05), the above four independent risk factors were used to construct the predictive model of COPD patients complicated with pulmonary tuberculosis. The internal and external validation showed that the area under the ROC curve was 0.797(95% CI: 0.699~0.894, P=0.000) and 0.810(95%CI: 0.673 ~ 0.913,P=0.000), respectively; The results of Hosmer-Lemeshow goodness-of-fit test were χ2=5.127(P=0.551) and χ2=5.489(P=0.530),respectively, indicating that the model has good performance and there is no significant difference between the predicted risk and the actual risk. Conclusion Age ≥ 70 years, smoking, long-term steroid use( > 3 months), and COPD course ≥ 10 years were the independent risk factors of COPD patients complicated with pulmonary tuberculosis, the risk prediction model based on this model has clinical application value in the identification of COPD complicated with pulmonary tuberculosis.
This study was designed to evaluate the effect of IL-10 on drug-resistance BCG acting on the production of inducible nitric oxide synthase(iNOS) and lactic acid by macrophages in vitro, providing the theoretical basis on screening the diagnosis and treatment of drug-resistance mycobacteria. The expression of STAT1 and STAT3 in macrophages were detected by Western blotting; the content of iNOS and lactic acid was determined by colorimetry. The levels of STAT1, STAT3, iNOS and lactic acid were also analyzed after knocking down IL-10 with small interfering RNA(si-IL-10). Data showed that under the condition of drug-sensitive BCG(S’and S groups), STAT1 was influenced in the group S’ with si-IL-10 or not, while drug-resistance BCG had weaker ability to induce STAT1 contrast with drug-susceptibility one; and STAT3 in the R’ group was remarkably less than that in the S’ group or R group(P=0.001 8; P=0.004 1). After si-IL-10, both of iNOS and lactic acid were ascended in the R’ group. In conclusion, the capacity of drug-resistance BCG to promote macrophage to differentiate into M2 and produce bactericidal enzymes are depended on IL-10.

On the first day of admission, the detection result of leukocytes, lymphocytes and neutrophils in asymptomatic patients were at normal levels. On the third day after admission, the results increased and continued to stabilize on the twelfth day. The levels of alanine aminotransferase and lactate dehydrogenase were at normal levels during hospitalization, without transient increase or decrease. The level of C-reactive protein reached the highest level on the third day after admission, but it was always in the normal range. D-dimer level was relatively stable during hospitalization. The absolute value of T cell subsets showed that the levels of CD 3+ , CD 4+ , CD 8+ T cells in asymptomatic infection patients were higher than those determined before admission. The average duration of pharyngeal nucleic acid positive detection in asymptomatic patients was 11.88 days. The average cycle threshold of ORF1ab gene and N gene was 36.94 and 35.43 respectively. Conclusions:The inflammatory reaction in patients with asymptomatic 2019-nCoV infection was mild, and the immune function was relatively good.

我国结核性胸腔积液的发病率近年来呈现明显的上升趋势,并且患者但往往就诊较晚,导致胸腔积液包裹或被分割成多个小房,导致常规治疗效果不理想。近年来研究[1,2]显示尿激酶、内科胸腔镜治疗结核性渗出性胸膜炎多房分隔均达到一定的疗效,但是2种治疗方案单独应用,同样存在治疗效果欠佳的局限性,为此本研究采用胸腔镜联合尿激酶对结核性胸膜炎多房分隔的患者进行治疗,现报告如下。
Tuberculosis (TB) is caused by infection of Mycobacterium tuberculosis. Host genetic variability is an important determinant of the risk of developing TB in humans. Although the association between MBL2 polymorphisms and TB has been studied in various populations, the results are controversial. In this study four functional single-nucleotide polymorphisms (SNPs, H/L, X/Y, P/Q and A/B) across the MBL2 gene were genotyped by direct DNA sequencing of PCR products in a case-control population of Chinese Han origin, consisting of 1,020 patients with pulmonary TB and 1,020 controls. We found that individuals carrying variant allele at A/B (namely BB or AB genotypes) was associated with increased susceptibility to TB (odds ratios [OR] = 1.57, 95% confidence interval [CI] 1.30–1.91, P = 1.3 × 10−6). Additionally, LYPB haplotype showed a significant association with increased risk of TB (OR = 1.54, 95% CI 1.27–1.87, P = 4.2 × 10−6; global haplotype association P = 3.5 × 10−5). Furthermore, individuals bearing low- or medium- MBL expression haplotype pairs had an increased risk of TB (OR = 1.56, 95% CI 1.29–1.90, P = 1.4 × 10−6). Thus, the reduced expression of functional MBL secondary to having MBL2 variants may partially mediate the increased susceptibility to TB risk.
