CRP, Procalcitonin and Pro-BNP as Diagnostic and Prognostic Markers in AECOPD

Acute Exacerbations of Chronic Obstructive Pulmonary Disease (AECOPD) are one of the chief causes for admission to Emergency Department. AECOPD is a significant cause for mortality and morbidity worldwide. Emergency Medicine Physicians frequently manage these patients. Predicting the severity and possible prognosis of AECOPD is an important task for Emergency Medicine Physicians as treatment options and aggressiveness may depend on these predictions. In our study we aimed to compare different biomarkers such as Procalcitonin, Pro-Brain Natriuretic Peptide (Pro-BNP) and C-Reactive Protein (CRP) on their efficacy at predicting the severity and prognosis of AECOPD. We analyzed the data of the selected 196 patients with the diagnosis AECOPD according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2024 guide who were admitted to our Emergency Department between 15/02/2023 and 15/02/2024.
