Brief Summary:
The purpose of the study is to investigate the plasma levels of Soluble Urokinase Plasminogen Activator Receptor (suPAR) at the diagnosis and after treatment of sepsis, and to determine whether it has a diagnostic and prognostic value in late-onset neonatal sepsis.

Condition or disease
Neonatal Sepsis

Detailed Description:
Infection is a leading cause of neonatal morbidity and mortality worldwide. The clinical presentation of neonatal infection is subtle and nonspecific. Microbiologic cultures of clinical specimens, the gold standard for diagnosis, have low sensitivity and are not available in time to influence initial therapy. Therefore, reliable and rapid in vitro tests are needed for early diagnosis and management of infection in neonates. suPAR, secreted from the cells (neutrophils, lymphocytes, macrophages, endothelial cells) has recently been reported to be a potential biomarker for several infection diseases. The levels of suPAR have not been studied in newborn infants yet.

Infants having clinical suspected late-onset neonatal sepsis enrolled in the study. Blood samples for suPAR were obtained before initiating antibiotic treatment and at the end of the treatment with other laboratory tests.
Infants without any clinical or hematological septic signs. Blood samples will be taken only once.

Primary Outcome Measures :
  1. Levels of suPAR in late-onset neonatal sepsis [ Time Frame: three weeks ]
    Levels of suPAR will be dosed with suspicion of late-onset sepsis diagnosis at day 0 and at the end of the treatment. The evolution and the best cut-off values will be calculated for the diagnosis. Indices of sensibility, specificity, positive predictive value and negative predictive value will be calculated.

Secondary Outcome Measures :
  1. Level of plasma C-reactive protein [ Time Frame: three weeks ]
    Plasma C-reactive protein levels to confirm the diagnostic usefulness of suPAR measurements at diagnosis and end of the treatment

  2. the white blood cell count [ Time Frame: three weeks ]
    the white blood cell counts to confirm the diagnostic usefulness of suPAR measurements at diagnosis and end of the treatment
