Methods: A total of 294 clinical cases of pulmonary tuberculosis (207 patients with APTB and 87 patients with IPTB) were retrospectively collected from January 2022 to February 2024 in The Affiliated Hospital of Hangzhou Normal University, and another 107 healthy medical checkups of the population in our hospital during the same period were collected as controls, and clinical information of the subjects in each group, IGRAs, and peripheral blood of PLT, erythrocyte sedimentation rate (ESR), neutrophils (NEU) were compared, lymphocytes (LY), hsCRP, monocytes (MO), and neutrophil-to-lymphocyte ratio (NLR) laboratory results, and to analyze the discriminatory performance of each index alone or in combination for APTB and IPTB. Results: There was no significant difference in the level of IGRAs in patients in the APTB group compared with the IPTB group;PLT count, ESR, NEU, MO, hsCRP, and NLR in patients in the APTB group were higher than those in the IPTB group;and LY count was lower than those in the IPTB group, and the difference was statistically significant (P < 0.05). The IGRAs in combination with the level of hsCRP and PLT was useful in distinguishing APTB and IPTB with an AUC value of 0.905, sensitivity of 81.2% and specificity of 85.2%. Conclusion: Differences in PLT and some inflammatory markers exist between APTB and IPTB patients, and IGRAs + hsCRP + PLT detection are valuable for differential diagnosis of APTB and IPTB.展开更多
