摘要
结核分枝杆菌是导致人类结核病最主要的病原体.常见的结核分枝杆菌检测方法主要有抗酸染色、罗氏培养法和γ干扰素释放试验,这些方法用于结核病的诊断耗时长且灵敏度较低,常常导致临床误诊、漏诊及治疗延误.近年来,结合多重聚合酶链反应(multiplex polymerase chain reaction,MPCR)扩增与高通量测序两种技术方法的靶向测序(targeted next-generation sequencing,tNGS)技术以其超广谱性、高灵敏度和高检出率等优点在临床检验领域受到越来越多关注,逐渐成为一种鉴定结核分枝杆菌的重要补充手段.本文报道了深圳市龙华区人民医院1例93岁男性重症肺炎患者,分析该患者治疗过程中的临床及影像学表现、病原体检测及诊疗过程,使用tNGS技术综合分析诊断,确诊为结核分枝杆菌合并多病原体混合感染,借此阐述tNGS在结核病早期诊断、混合感染识别及疾病监测和疗效评估中的潜在应用价值,提升临床对结核分枝杆菌鉴别诊断水平,同时提高临床医务工作者对于tNGS技术在感染性疾病病原鉴定中应用的认识.
Abstract
Mycobacterium tuberculosis is the primary causative agent of human tuberculosis.Conventional detection methods for Mycobacterium tuberculosis,such as acid-fast staining and Roche culture method and Interferon gamma release assay(IGRA),are time-consuming and have low sensitivity in diagnosing tuberculosis,often leading to clinical misdiagnosis,missed diagnosis,and treatment delays.In recent years,the integration of targeted Next-generation sequencing(tNGS)technology with Multiplex polymerase chain reaction(MPCR)amplification and high-throughput sequencing has gained increasing attention in the field of clinical testing due to its advantages of rapidity,ultra-broad spectrum,high sensitivity and high detection rate.It has gradually emerged as an important complementary approach for identifying Mycobacterium tuberculosis.This paper reported a 93-year-old male patient with severe pneumonia in the Longhua District People's Hospital of Shenzhen.The clinical manifestation,imaging examination,pathogen detection and treatment process were analyzed.The patient was finally diagnosed as Mycobacterium tuberculosis complicated with multi-pathogen infection by tNGS.tNGS showed potential value in earlier diagnosis,mixed infection identification,surveillance and therapeutic efficacy evaluation.This not only enhances the clinical differential diagnosis of Mycobacterium tuberculosis but also advances the understanding among healthcare professionals regarding the application of tNGS in pathogen identification for infectious diseases.
