ObjectiveTo evaluate the expression level and diagnostic value of lnc-PAPSS2-2 (lnc-PA) in peripheral blood of active pulmonary tuberculosis (PTB) patients.MethodsFrom January 2011 to January 2018, 798 patients with active PTB and 1 650 healthy people undergoing health examination in West China Hospital of Sichuan University and their electronic health records (EHR) were collected. Peripheral blood lnc-PA levels were quantified by quantitative real-time polymerase chain reaction method. The data of lnc-PA and EHR were modeled using nomogram, and the receiver operating characteristic (ROC) curves of lnc-PA, EHR and the combination of lnc-PA and EHR were compared to evaluate the diagnostic value of lnc-PA for active PTB.ResultsThe level of lnc-PA was lower in active PTB patients than that in healthy controls (P<0.001). The areas under ROC curve of lnc-PA, EHR and their combination were 0.619, 0.962, and 0.964 in the training set and 0.626, 0.950, and 0.950 in the validation set, respectively.ConclusionThe diagnostic ability of lnc-PA is poor and that of EHR is good, which indicates that the clinical value of lnc-PA as a biomarker of active PTB remains to be further explored.
