To evaluate the diagnostic accuracy of tuberculosis RNA (TB-RNA) for the rapid diagnosis of bone and joint tuberculosis (BJTB).
We conducted a retrospective study to evaluate the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the curve (AUC) of TB-RNA and acid-fast bacillus (AFB) smear against the final clinical diagnosis.
A total of 268 patients were included. The overall sensitivity, specificity, PPV, NPV, and AUC of AFB smear for BJTB were 0.7%, 100.0%, 100.0%, 49.3%, and 0.50, respectively, whereas those of TB-RNA were 59.6%, 100.0%, 100.0%, 70.6%, and 0.80, respectively; for cases of confirmed (culture-positive) BJTB, these values were 82.8%, 99.4%, 99.7%, 89.2%, and 0.91, respectively.
The diagnostic accuracy of TB-RNA in the rapid diagnosis of BJTB was relatively good, especially in culture-positive BJTB. The use of TB-RNA could be an effective technique for the rapid diagnosis of BJTB.
评估结核 RNA（TB-RNA）在快速诊断骨与关节结核（BJTB）中的诊断准确性。
我们进行了一项回顾性研究，以评估 TB-RNA 和抗酸杆菌（AFB）涂片相对于最终临床诊断的敏感性、特异性、阳性预测值（PPV）、阴性预测值（NPV）和曲线下面积（AUC）。
共纳入 268 例患者。AFB 涂片对 BJTB 的总体敏感性、特异性、PPV、NPV 和 AUC 分别为 0.7%、100.0%、100.0%、49.3%和 0.50，而 TB-RNA 分别为 59.6%、100.0%、100.0%、70.6%和 0.80；对于确诊（培养阳性）BJTB 病例，这些值分别为 82.8%、99.4%、99.7%、89.2%和 0.91。
TB-RNA 在快速诊断 BJTB 中的诊断准确性相对较好，尤其是在培养阳性的 BJTB 中。TB-RNA 的使用可能是一种快速诊断 BJTB 的有效技术。
