The value of serum procalcitonin in differential diagnosis of pulmonary embolism and community-acquired pneumonia.
Presence of high fever may cause confusion in differential diagnosis of pulmonary embolism (PE) versus pneumonia. The aim of this study is to investigate the diagnostic value of serum procalcitonin (PCT) in differential diagnosis of PE and community-acquired pneumonia (CAP). A total of 24 patients with proven PE and 22 patients with CAP were included in the study. ⋯ There were no statistically significant reduction in PCT levels by anticoagulation in groups 1 and 2 (P = .262, .119, respectively). Other systemic inflammatory markers including interleukin 6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor α (TNF-α) levels statistically significantly decreased with anticoagulant and antimicrobial therapy. This study suggested that serum PCT level may be valuable for differentiating PE patients with or without fever from patients with CAP.
