Methods We assessed clinical parameters and five biomarkers the precursor levels of adrenomedullin ADM endothelin-1 ET1 atrial-natriuretic peptide ANP anti-diuretic hormone copeptin and procalcitonin in patients with LRTI and CAP enrolled in the multicenter ProHOSP study. We compared the prognostic accuracy of these biomarkers with the pneumonia severity index PSI and CURB65 Confusion Urea Respiratory rate Blood pressure Age 65 score to predict serious complications defined as death ICU admission and disease-specific complications using receiver operating curves ROC and reclassification methods. Results During the 30 days of follow-up 134 serious complications occurred in 925 patients with CAP Both PSI and CURB65 overestimated the observed mortality X2 goodness of fit test P and . ProADM or proET1 alone had stronger discriminatory powers than the PSI or CURB65 score or any of either score components to predict serious complications. Adding proADM alone or all five biomarkers jointly to the PSI and CURB65 scores significantly increased the area under the curve AUC for PSI from to and for CURB65 from to P .
