Interleukin-1 receptor antagonist as a biomarker of sepsis in neutropenic haematological patients. EUROPEAN JOURNAL OF HAEMATOLOGY, 101 (5) , 691-698. 10.1111/ejh.13161.
The study aim was to compare the performance of interleukin‐1 receptor antagonist (IL‐1Ra) to C‐reactive protein (CRP) and procalcitonin (PCT) in early prediction of the clinical course of febrile neutropenia.
The study population consisted of 86 consecutive patients with febrile neutropenia who received intensive chemotherapy for haematological malignancy between November 2009 and November 2012 at the adult haematology ward of Kuopio University Hospital. Twenty‐three (27%) patients had acute myeloid leukaemia and 63 (73%) patients were autologous stem cell transplant recipients. IL‐1Ra, CRP and procalcitonin were measured at the onset of fever (d0), on day 1 (d1) and on day 2 (d2).
Eight patients developed severe sepsis, including three patients with septic shock. Eighteen patients had bacteraemia. After the onset of febrile neutropenia Youden´s indices (with their 95% confidence intervals) to identify severe sepsis were for IL‐1Ra on d0 0.57 (0.20‐0.71) and on d1 0.65 (0.28‐0.78), for CRP on d0 0.41 (0.04‐0.61) and on d1 0.47 (0.11‐0.67) and for PCT on d0 0.39 (0.05‐0.66) and on d1 0.52 (0.18‐0.76).
In haematological patients, IL‐1Ra has a comparable capacity with CRP and PCT to predict severe sepsis at the early stages of febrile neutropenia.
