Abstract

Objectives: The long pentraxin PTX3 is a promising marker of disease severity in severely ill patients. In order to identify patients warranting critical care as quickly as possible, we investigated the value of PTX3 as a biomarker for disease severity in patients presenting with fever at the emergency department. Methods: Levels of PTX3 were measured in 211 febrile patients at the emergency and the levels were linked to markers of disease severity including admittance to a special care unit, bloodstream infection and congestive heart failure. Results: In comparison to median baseline levels of 2.30 ng/ml (interquartile range 1.66-3.67 ng/ml), levels of PTX3 were significantly elevated in patients admitted to the intensive/medium care unit (median value 44.4 ng/ml, interquartile range 13.6-105.9 ng/ml) and in patients referred to the ward (median value 14.2 ng/ml, interquartile range 7.01-25.1 ng/ml). In addition, PTX3 was associated with duration of hospital stay and acute congestive heart failure. The levels were predictive for bloodstream infection (AUC = 0.71; 95% CI 0.62-0.81). Conclusions: PTX3 may be a useful marker for differentiation of patients with severe disease in patients presenting with fever to the emergency department.
