Presepsin in the Diagnosis of Sepsis in Critically Ill Patients

Overview

Sepsis is one of the most common causes of death worldwide. It is caused by a complex of inadequate host responses to infection. Sepsis remains a major challenge of modern intensive care medicine. Despite recent improvements, the incidence of sepsis in critically ill patients increases steadily (25%) and mortality rates remain unacceptably high (30%). It is difficult to distinguish the sepsis from the non-infectious systemic inflammatory response syndrome. Early identification of the origin of infection can help dramatically to improve outcome and reduce mortality. That is why clinicians need fast, reliable and specific biomarkers for sepsis recognition.

Comparison between the detection of novel early inflammatory biomarker (PSEP) and the others normally used biomarkers (c-reactive protein - CRP, interleukin 6 - IL6, procalcitonin - PCT) in the early diagnosing of sepsis in the critically ill patients A broad range of clinical and laboratory parameters are combined (Surviving sepsis campaign, international guidelines) for early sepsis identification: white blood cells (WBC), C-reactive protein (CRP), interleukin 6 (IL-6), procalcitonin (PCT). An ideal biomarker should be a fast and specific increase in sepsis, short half-life, rapid decrease after administration of an effective therapy and fast (bed-side) method of determination. None of the current biomarkers have all of these characteristics. We investigate the diagnostic accuracy of presepsin compared to other biomarkers (WBC, PCT, IL6, CRP) for infection or sepsis, defined according to Sepsis-3 definition (Singer, JAMA 2016) in adult patients admitted to ICU with suspected sepsis.
