Clinical Characteristics Of Bronchoalveolar Lavage Fluid X-Pert MTB/RIF And Smear Negative Pulmonary Tuberculosis

OBJECTIVE:This study aims to explore the clinical analysis between Xpert MTB/RIF results using bronchoalveolar lavage fluid as a sample and the clinical features of smear-negative pulmonary tuberculosis.Methods:Retrospective analysis of patients diagnosed with tuberculosis,bronchoscopy and alveolar lavage,these patients were hospitalized in the Respiratory and Critical Care Center of Shine Medical University Affiliated Hospital from November 2018 to October 2020.Collected clinical data and data.The content includes general clinical data submitted for X-Pert MTB/RIF test results,clinical symptoms,lung CT features,bronchoscopy and bronchoalveolar lavage fluid.Results:205 eligible patients underwent retrospective screening,including 107 males and 98 females aged 16-90,with an average age(54.902±16.574).The results showed that smear-negative tuberculosis with a positive Xpert test has a high risk of chest tightness,hemoptysis,and fever,a high risk of cavitation and calcification in diagnostic imaging,and a relatively high risk of bilateral lung lobes.Participation,I proved it.Things like changes or pleurisy.In addition,bronchoscopy is more likely to detect caseous necrosis,ulcers and white pseudomembranes of the tracheal mucosa.Conclusion:1.The results of Xpert MTB/RIF examination with bronchoalveolar lavage fluid as the specimen have high clinical application value in the clinical diagnosis of smear-negative pulmonary tuberculosis.2.Xpert have certain differences in pulmonary tuberculosis patients with different clinical characteristics.3.Smear-negative pulmonary tuberculosis is a type of disease that is difficult to diagnose for pulmonary tuberculosis.The combination of multiple diagnostic methods is the future way out for a clear diagnosis.
