The purpose of this study is to validate presepsin as a biological marker for identifying bacterial fever among febrile syndromes of infants under three months of age. Clearly, our goal is to determine if this marker can help us distinguish a viral infection from a bacterial infection. Indeed, presepsin would be specific for bacterial infection, and rise earlier in the blood during infection than biological markers currently used. Such validation could improve the precocity of the therapeutic management by a better targeted antibiotic therapy, and the limitation of invasive complementary examinations (lumbar puncture), in infants for whom the fear of a bacterial infection leads to examinations and systematic treatments.
An exploratory proof of concept that evaluates an innovative and minimally invasive diagnostic technique, with brief, monocentric longitudinal follow-up, this study aims to validate presepsin as a biomarker for identifying bacterial fever among febrile syndromes of infants under three months of age. Presepsin is thought to be specific for sepsis, and would rise earlier in the blood during sepsis than biomarkers currently used. Such validation could improve the precocity of the therapeutic management by a better targeted antibiotic therapy, and the limitation of invasive complementary examinations (lumbar puncture), in infants for whom the fear of a bacterial infection leads to examinations and systematic treatments.
To do this, we will study the discriminative power (bacterial or viral, verified, a posteriori, by the results of microbiological examinations such as blood cultures, cytobacteriology of urine, lumbar puncture, virological or bacteriological samples of stool and nasopharynx) and prognosis (comparison of initial signs of clinical severity and presepsin levels, length of hospitalization and hospitalization unit) of presepsin by comparing its blood levels to the usual biological markers (CRP, PCT, leukocytes, neutrophils, lymphocytes) in children less than 3 months old with fever. It will also be compared, a posteriori, the rate of presepsin between the group of children treated with antibiotics and the group of untreated children to verify that the rate of presepsin is predictive of the initiation of antibiotic treatment.
If in this study the superiority of presepsin is confirmed, it will also be evaluated, by a medico-economic study, the effect of a decision of care based on the interpretation of the blood presepsin level on downstream health costs and on the speed of care of children under 3 months with fever presenting to the emergency department by the commissioning of a delocalized analyzer. This device is, for the moment, available only in the laboratory.
The study plans to include 160 children under 3 months admitted to pediatric emergencies or pediatric resuscitation at Estaing Hospital in Clermont-Ferrand.
Participation in the study will not require additional venipuncture given the very small amount of blood sufficient for the presepsin assay. The diagnosis of the child will not be made according to the presepsin test, but according to the standard criteria, and its management will not be modified by his participation in the study. Thus, the study presents neither benefit nor risk for the participants.

| Prespesin assay on PATHFAST analyser | Diagnostic Test | Collection of parental non-opposition by the doctor taking care of the child. Addition of an additional 500μl tube to the usual blood sampling as part of the protocol for the management of children under 3 months of age with fever. This blood test contains CRP, PCT, NFS, Hemoculture. There is no additional venipuncture. This blood sample is taken by the nurse after parental non-opposition. Transfer of the sample to the laboratory. In the laboratory, centrifugation of the sample, taking the plasma alone which will be frozen. Delayed assay of presepsin, in series, after thawing of samples. Collection of data and analyzes by the principal investigator in collaboration with the statistician methodologist. The immunoassay of presepsin with PATHFAST is based on chemiluminescence. |
