OBJECTIVE: To investigate the diagnostic efficacy of nanopore sequencing technology in tuberculous meningitis (TBM).
METHODS: Cerebrospinal fluid samples were collected from patients for acid-fast staining microscopy, Mycobacterium tuberculosis solid culture, DNA detection, and nanopore sequencing. Lastly, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the receiver operating characteristic curve (AUC) were calculated and compared among these detection methods.
RESULTS: In this study, 30 TBM patients and 18 non-TBM patients were included. Nanopore sequencing showed higher sensitivity (43.30 %) and AUC (0.661) compared to the other methods. Combining nanopore sequencing and imaging achieved the highest diagnostic performance with sensitivity (60.00 %), specificity (88.90 %), PPV (90.00 %), NPV (57.10 %), and AUC (0.744).
CONCLUSION: Nanopore sequencing demonstrated superior diagnostic accuracy for TBM, outperforming acid-fast staining, Mycobacterium tuberculosis culture, and DNA detection. When combined with imaging, nanopore sequencing significantly enhanced diagnostic sensitivity and accuracy for TBM.
