Diagnostic value of sepsis biomarkers in hematopoietic stem cell transplant recipients in a condition of high prevalence of gram-negative pathogens
Objective / background: A decision about the need for antimicrobial therapy in a patient with febrile neutropenia after hematopoietic stem cell transplantation (HSCT) is often complicated because of the low frequency of culture isolation and reduced clinical manifestation of infection. Usefulness and choice of sepsis biomarkers to distinguish bloodstream infection (BSI) from other causes of febrile episode is still argued in HSCT recipients in modern epidemiological situations characterized by the emergence of highly resistant gram-negative microorganisms. In this study a comparative analysis of diagnostic values of presepsin, procalcitonin (PCT), and C-reactive protein (CRP) was performed as sepsis biomarkers in adult patients after HSCT in a condition of high prevalence of gram-negative pathogens.
