[PMID: 38560467 PMCID: PMC10979740 DOI: 10.7717/peerj.17164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 03/06/2024] [Indexed: 04/04/2024] Open
Abstract
Objective This study aimed to create a predictive model based on machine learning to identify the risk for tracheobronchial tuberculosis (TBTB) occurring alongside Mycoplasma pneumoniae pneumonia in pediatric patients. Methods Clinical data from 212 pediatric patients were examined in this retrospective analysis. This cohort included 42 individuals diagnosed with TBTB and Mycoplasma pneumoniae pneumonia (combined group) and 170 patients diagnosed with lobar pneumonia alone (pneumonia group). Three predictive models, namely XGBoost, decision tree, and logistic regression, were constructed, and their performances were assessed using the receiver's operating characteristic (ROC) curve, precision-recall curve (PR), and decision curve analysis (DCA). The dataset was divided into a 7:3 ratio to test the first and second groups, utilizing them to validate the XGBoost model and to construct the nomogram model. Results The XGBoost highlighted eight significant signatures, while the decision tree and logistic regression models identified six and five signatures, respectively. The ROC analysis revealed an area under the curve (AUC) of 0.996 for XGBoost, significantly outperforming the other models (p < 0.05). Similarly, the PR curve demonstrated the superior predictive capability of XGBoost. DCA further confirmed that XGBoost offered the highest AIC (43.226), the highest average net benefit (0.764), and the best model fit. Validation efforts confirmed the robustness of the findings, with the validation groups 1 and 2 showing ROC and PR curves with AUC of 0.997, indicating a high net benefit. The nomogram model was shown to possess significant clinical value. Conclusion Compared to machine learning approaches, the XGBoost model demonstrated superior predictive efficacy in identifying pediatric patients at risk of concurrent TBTB and Mycoplasma pneumoniae pneumonia. The model's identification of critical signatures provides valuable insights into the pathogenesis of these conditions.

Development, assessment and validation of a novel prediction nomogram model for risk identification of tracheobronchial tuberculosis in patients with pulmonary tuberculosis. BMJ Open Respir Res 2023; 10:e001781. [PMID: 37931979 PMCID: PMC10632898 DOI: 10.1136/bmjresp-2023-001781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Accepted: 10/20/2023] [Indexed: 11/08/2023] Open
Abstract
OBJECTIVE Tracheobronchial tuberculosis (TBTB), a specific subtype of pulmonary tuberculosis (PTB), can lead to bronchial stenosis or bronchial occlusion if not identified early. However, there is currently no available means for predicting the risk of associated TBTB in PTB patients. The objective of this study was to establish a risk prediction nomogram model for estimating the associated TBTB risk in every PTB patient. METHODS A retrospective cohort study was conducted with 2153 PTB patients. Optimised characteristics were selected using least absolute shrinkage and selection operator regression. Multivariate logistic regression was applied to build a predictive nomogram model. Discrimination, calibration and clinical usefulness of the prediction model were assessed using C-statistics, receiver operator characteristic curves, calibration plots and decision analysis. The developed model was validated both internally and externally. RESULTS Among all PTB patients who underwent bronchoscopies (n=2153), 40.36% (n=869) were diagnosed with TBTB. A nomogram model incorporating 11 predictors was developed and displayed good discrimination with a C-statistics of 0.782, a sensitivity of 0.661 and a specificity of 0.762 and good calibration with a calibration-in-the-large of 0.052 and a calibration slope of 0.957. Model's discrimination was favourable in both internal (C-statistics, 0.782) and external (C-statistics, 0.806) validation. External validation showed satisfactory accuracy (sensitivity, 0.690; specificity, 0.804) in independent cohort. Decision curve analysis showed that the model was clinically useful when intervention was decided on at the exacerbation possibility threshold of 2.3%-99.2%. A clinical impact curve demonstrated that our model predicted high-risk estimates and true positives. CONCLUSION We developed a novel and convenient risk prediction nomogram model that enhances the risk assessment of associated TBTB in PTB patients. This nomogram can help identify high-risk PTB patients who may benefit from early bronchoscopy and aggressive treatment to prevent disease progression.

Abstract
OBJECTIVES To study the clinical and bronchoscopic characteristics of tracheobronchial tuberculosis (TBTB) in children and to identify factors influencing residual airway obstruction or stenosis. METHODS The clinical data of children with TBTB were retrospectively collected. The children were divided into two groups based on the last bronchoscopic result within one year of follow-up: a group with residual airway obstruction or stenosis (n=34) and a group without residual airway obstruction or stenosis (n=58). A multivariate logistic regression analysis was used to identify the factors influencing residual airway obstruction or stenosis in children with TBTB. Receiver operating characteristic (ROC) curves were used to analyze the predictive value of the factors influencing residual airway obstruction or stenosis in children with TBTB. RESULTS A total of 92 children with TBTB were included, and the main symptoms were cough (90%) and fever (68%). In children under 1 year old, the incidence rates of dyspnea and wheezing were significantly higher than in other age groups (P<0.008). Chest CT findings included mediastinal or hilar lymph node enlargement (90%) and tracheobronchial stenosis or obstruction (61%). The lymphatic fistula type was the main type of TBTB observed bronchoscopically (77%). All children received interventional treatment, and the effective rate was 84%. During one year of follow-up, 34 children had residual airway obstruction or stenosis. The TBTB diagnostic time and the initiation of interventional treatment were significantly delayed in the group with residual airway obstruction or stenosis compared with the group without residual airway obstruction or stenosis (P<0.05). The multivariate logistic regression analysis showed that the TBTB diagnostic time was closely related to residual airway obstruction or stenosis in children (P<0.05). ROC curve analysis showed that at the cut-off value of 92 days of TBTB diagnostic time, the area under the curve for predicting residual airway obstruction or stenosis in children with TBTB was 0.707, with a sensitivity of 58.8% and a specificity of 75.9%. CONCLUSIONS The clinical manifestations of TBTB are nonspecific, and symptoms are more severe in children under 1 year old. TBTB should be suspected in children with tuberculosis and chest imaging indicating airway involvement. Delayed diagnosis of TBTB is associated with the development of residual airway obstruction or stenosis.

Abstract
Background Tracheobronchial stenosis, particularly central airway stenosis, which frequently results in severe complications such as lung damage, occurs in patients with tracheobronchial tuberculosis (TBTB). Objectives To analyze the clinical characteristics of patients with central airway stenosis due to tuberculosis (CASTB). Methods Retrospective analysis was performed on the clinical features, radiological features, bronchoscopic features and treatment of 157 patients who were diagnosed with CASTB in two tertiary hospitals in Chongqing, China, from May 2020 to May 2022. Results CASTB mostly occurs in young patients and females. Patients with CASTB exhibited different symptoms repeatedly during the disease, especially varying degrees of dyspnea, prompting many patients to undergo bronchoscopic intervention and even surgery. Patients with cicatricial strictures constituted the highest proportion of the TBTB subtype with CASTB and 35.7% of the patients with CASTB were found to have tracheobronchomalacia (TBM) under bronchoscopy. CASTB and TBM mainly involved the left main bronchus. Patients with lower levels of education had higher rates of TBM. Patients with TBM manifested shortness of breath more frequently than patients without TBM. Patients with TBTB who had undergone bronchoscopic interventions have a higher rate of TBM. Conclusions Despite mostly adequate anti-tuberculosis chemotherapy, patients with TBTB can present with CASTB involving severe scarring stenosis, bronchial occlusion, tracheobronchomalacia and even destroyed lung.

Sex-Specific Differences in the Clinical Profile Among Patients with Tracheobronchial Tuberculosis: A Hospital-Based Cross-Sectional Study in Shenzhen, China. Int J Gen Med 2022; 15:5741-5750. [PMID: 35761894 PMCID: PMC9233510 DOI: 10.2147/ijgm.s367070] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 06/01/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose Tracheobronchial tuberculosis (TBTB) has been proposed to occur more commonly in female patients. However, to date, studies that systematically delineate differences between female and male patients with TB infection are lacking. We aimed to comprehensively assess the sex-specific differences in clinical manifestation, bronchoscopy performance, bacteriological examination, and imaging of TBTB in Shenzhen, China. Methods All patients with diagnosed TBTB from August 1, 2018 to July 31, 2021 at The Third People’s Hospital of Shenzhen were enrolled in the present study. Demographic information, clinical manifestations, blood tests, chest computed tomography, and bronchoscopic findings were collected, and assessed their sex-specific differences. Results Of these 331 patients, 238 patients (71.9%) were female, and 93 patients (28.1%) were male, with an overall average age of 37.3 years. The average age of male patients with TBTB was more than 5 years older than that of female patients. The prevalence of lymph fistula and diabetes mellitus was significantly higher in male patients than female patients (8.6% vs 1.7%, P = 0.005; 17.2% vs 2.1%, P < 0.001). The positive proportion of sputum smear was higher in male patients (27.9%) than in female patients (16.7%, P = 0.026). Moreover, the mean monocyte-to-lymphocyte ratio, serum CRP, and IL-6 levels were significantly higher in male patients than in female patients (P < 0.05). Conclusion In summary, in patients with TBTB diagnosis, male sex was associated with a high prevalence of diabetes mellitus, lymph fistula, and smear-positive ratio, as well as high inflammation levels. The management of young female and male patients with diabetes mellitus and high inflammation levels should be strengthened. Furthermore, to reduce the burden of TBTB, we must pay attention to the risk of TBTB in past tuberculosis patients, especially male patients under 45 years old and female patients over 45 years old.
