Prognostic value of pro-adrenomedullin and NT-proBNP in patients referred from the emergency department with influenza syndrome.

Objectives: To assess the prognostic value of procalcitonin (PTC), C-reactive protein (CRP), N-terminal prohormone of brain natriuretic peptide (NT-proBNP), and mid-regional pro-adrenomedullin (MR-proADM) in patients with influenza syndrome.

Material And Methods: Prospective study in patients admitted from the emergency department with influenza syndrome. Biomarker concentrations were measured in the first 24 h after admission and a test for influenza.
