摘要
BACKGROUND: Tuberculosis (TB), primarily caused by Mycobacterium tuberculosis, remains a significant global health concern. Targeted Next-Generation Sequencing (tNGS) has emerged as a rapid and comprehensive diagnostic tool for tuberculosis, offering advantages over traditional methods and serving as an effective alternative for drug susceptibility testing and the detection of drug-resistant tuberculosis. OBJECTIVE: This study aimed to retrospectively analyze the clinical characteristics of pulmonary tuberculosis patients. After explore the application value of targeted next-generation sequencing technology in this patient population, providing valuable insights for clinical diagnosis and treatment. METHODS: In this retrospective study, we analyzed data from 65 patients with laboratory-confirmed tuberculosis admitted to Tianjin Baodi Hospital from November 14, 2020, to February 1, 2023. Patients underwent bronchoalveolar lavage fluid (BALF) testing, including acid-fast staining, culture, and tNGS. Biopsies and histopathological examinations were performed on some patients, along with comprehensive radiological assessments for all. RESULTS: Among the 65 pulmonary tuberculosis patients, targeted next-generation sequencing detected pathogens in bronchoalveolar lavage fluid with a positivity rate of 93.8%, significantly higher than traditional methods such as acid-fast staining, culture, and pathology. Compared to bronchoalveolar lavage fluid smear, targeted next-generation sequencing demonstrated significantly higher diagnostic sensitivity (98.46% vs. 26.15%) and accuracy (98.46% vs. 26.15%). CONCLUSION: Targeted next-generation sequencing, with its high sensitivity and specificity compared to traditional methods, provides unique advantages in detecting pathogens among these patients, highlighting its importance in disease management.
