Abstract：Objective To investigate the temporal predictive value of soluble triggering receptor expressed on myeloid cells-1(sTREM-1),procalcitonin(PCT),and myeloid-related protein 8/14(MRP8/14)for secondary acute respiratory distress syndrome(ARDS)in patients with severe pulmonary tuberculosis.Methods A retro-spective cohort study was conducted among patients with severe pulmonary tuberculosis admitted between January 2021 and December 2024.Patients were randomly assigned in an 8∶2 ratio to a training set(n=148)and a valida-tion set(n=37).Serum sTREM-1,PCT,and MRP8/14 were extracted from the electronic medical record at three time points:on admission(day 0),day 3,and day 7.Multivariable logistic regression was used to identify risk factors,and predictive performance was evaluated using receiver operating characteristic(ROC)curves.Results A total of 185 patients were included.In the training set(n=148),27 developed ARDS and 121 did not;in the validation set(n=37),7 developed ARDS and 30 did not.In the training set,serum sTREM-1,PCT,and MRP8/14 levels showed significant temporal changes(P<0.05).At admission,day 3,and day 7,levels of sTREM-1,PCT,and MRP8/14 were higher in the ARDS group than in the non-ARDS group(all P<0.05).At each time point,sTREM-1,PCT,and MRP8/14 were independently associated with the development of ARDS(P<0.05).In the training set,the combination of sTREM-1,PCT,and MRP8/14 at admission yielded the largest area under the ROC curve[AUC=0.976;95%confidence interval(CI),0.952～1.000],with a sensitivity of 88.9%and a specificity of 98.3%.In the validation set,the same combination achieved an AUC of 0.957(95%CI,0.895～1.000),with a sensitivity of 100.0%and a specificity of 86.7%.Conclusion Dynamic changes in sTREM-1,PCT,and MRP8/14 provide temporal predictive value for ARDS in patients with severe pulmonary tuberculosis,and the combined assessment improves early warning accuracy.
