Brief Summary:
LIAISON® PTX3 is an in vitro chemiluminescent immunoassay (CLIA) intended for the quantitative determination of Long Pentraxin 3 (PTX3) in human plasma samples.
LIAISON® PTX3, in conjunction with clinical evaluation and other laboratory findings, may serve as an aid in the determination of disease severity and prognosis of patients with community-acquired (CAP) and hospital-acquired pneumonia (HAP), including ventilator-associated pneumonia (VAP).
Detailed Description:
Long Pentraxin 3 (PTX3) is an essential protein of innate immunity, produced by myeloid cells, endothelial cells and respiratory epithelial cells, and involved in resistance to selected pathogens and in inflammation. In different pathological conditions (infections of bacterial and viral origin, sepsis, and cardiovascular diseases) and in patients requiring admission to intensive care units (ICUs), PTX3 was detected in high concentrations in the circulation and was associated with disease severity and mortality.
PTX3 plasma concentration was found to be an independent prognostic indicator of short-term mortality (28 days) in hospitalized patients with Coronavirus Disease 2019 (COVID- 19) and higher PTX3 levels were found in ICU patients compared to ward patients. Moreover, PTX3 significantly correlated with the inflammatory molecules C-reactive protein (CRP), procalcitonin (PCT), and interleukin (IL)-6.
Given the association between PTX3 and inflammatory conditions, especially in the context of lung infections, the study aims to investigate the potential of PTX3 to be used as a severity marker and a prognostic predictor for outcome in patients with community-acquired (CAP) and hospital-acquired pneumonia (HAP), including ventilator-associated pneumonia (VAP).
