Background Infection is a common problem in emergency departments ( ED s) and is associated with high mortality, morbidity and costs. Identifying infection in ED patients can be challenging. Biomarkers can facilitate its diagnosis, enabling an early management and improving outcomes. In the critical care setting, two emerging biomarkers, pancreatic stone protein ( PSP ) and soluble CD 25 ( sCD 25), have demonstrated to be useful for diagnosis of sepsis. We aimed to assess the diagnostic value of these biomarkers, in comparison with procalcitonin ( PCT ), for infection and sepsis in an ED population with suspected infection. Materials and methods Through a prospective, observational study, we investigated the utility of serum PCT , PSP and sCD 25 levels, measured on admission, for diagnosis of infection and sepsis, defined according to the recently updated for sepsis (Sepsis‐3), in patients presenting to the ED for suspected infection. Diagnostic accuracy was evaluated by using receiver operating characteristic curves ( ROC ) analysis. Results Of the 152 patients enrolled in this study, 129 had a final diagnosis of infection, including 82 with noncomplicated infection and 47 with sepsis. Median PCT , PSP and sCD 25 levels were significantly higher in patients with infection and sepsis. The ROC curve analysis revealed a similar diagnostic accuracy for infection ( ROC area under the curve ( AUC ) PCT : 0·904; sCD 25: 0·869 and PSP : 0·839) and for sepsis ( ROC AUC : PCT : 0·820; sCD 25: 0·835 and PSP : 0·872). Conclusions Pancreatic stone protein and sCD 25 perform well as infection and sepsis biomarkers, with a similar performance than PCT , in ED patients with suspected infection. Further larger studies investigating use of PSP and sCD 25 are needed.
