“…Biomarkers (C-reactive protein (CRP)) [228,[261][262][263][264], procalcitonin (PCT) [228,263,265,266], D-dimer [267], carboxy-terminal provasopressin (CT-proAVO, copeptin) [268], midregional proatrial natriuretic peptide (MR-pro-ANP) [266,269,270], midregional proadrenomedullin (MR-ADM) [271,272], and triggering receptor expressed on myeloid cells (TREM-1) [273], as well as the adrenal response [274,275], as an alternative or additional tool for the assessment of pneumonia severity, have recently gained much attention.
