Abstract

<abstract abstract-type="main" id="joim12238-abs-0001"> <title>Abstract</title> <sec id="joim12238-sec-0001" sec-type="section"> <title>Objective</title> <p>The soluble urokinase plasminogen activator receptor (suPAR) reflects inflammation. However, the prognostic value of suPAR measurements, particularly at the very early onset of systemic inflammatory response syndrome (SIRS), is less well defined.</p> </sec> <sec id="joim12238-sec-0002" sec-type="section"> <title>Methods</title> <p>The prognostic potential of suPAR levels in patients with SIRS was evaluated. From November 2010 until April 2013, 902 adult patients presenting with SIRS were investigated.

AUCs for procalcitonin (0.777, 0.671 and 0.638), interleukin‐6 (0.709, 0.593 and 0.569) and C‐reactive protein (0.66, 0.594 and 0.586) as well as renal function and age were markedly lower. Using multivariable regression analyses, suPAR levels (<italic>P</italic> < 0.001) remained significant predictors of 48‐h mortality, whereas suPAR levels (<italic>P</italic> < 0.001) and bacteraemia (<italic>P</italic> = 0.002 and <italic>P</italic> = 0.001, respectively) remained significant predictors of 30‐ and 90‐day mortality. Using Kaplan–Meier survival plots, patients with suPAR <9.15 ng mL<sup>−1</sup> at SIRS onset had a clear benefit.</p> </sec> <sec id="joim12238-sec-0004" sec-type="section"> <title>Conclusion</title> <p>suPAR plasma level determined at early SIRS is predictive for mortality.</p> </sec> </abstract>
