Objective: This study was performed to investigate serum concentration of procalcitonin during neonatal sepsis in the first month of life and to evaluate the usefulness of procalcitonin as a diagnostic and prognostic test for neonatal infections. And to compare procalcitonin with C Reactive Protein (CRP), Tumor Necrosis Factor-a (TNF-a), Interleukin-6 (IL-6) and Interleukin-8 (IL-8).

Materials: 26 patients with neonatal sepsis and 29 sex, gestational age, postnatal age and weight matched healthy control subjects were admitted to the study. Serum levels of procalcitonin, IL-6, IL-8, (TNF-a), CRP and immature/total neutrophil ratio were measured in early and late neonatal sepsis and single sample in healthy control subjects.

Results: Plasma procalcitonin, CRP, IL-6, IL-8, (TNF-a) concentrations in the patients group were significantly higher than the control groups. There was no significant difference in the serum IL-6, IL-8, (TNF-a) procalcitonin levels with blood culture positive patients and clinical sepsis. With the establishment of antibiotherapy, a significant decrease in plasma procalcitonin, IL-6, IL-8, (TNF-a), immature/matur neutrophil ratio concentrations was observed in the survival group. However nonsignificant decrease in plasma CRP concentration was observed in this group. With the establishment of therapy, a significant increase in plasma procalcitonin, IL-6, IL-8, (TNF-a), immature/matter neutrophil ratio was observed in the nonsurvival group. Serum procalcitonin level *0.3 ng/ml and TNF-* level *10 pg/ml had a sensitivity and specifity of up to %100 in the diagnosis of neonatal sepsis.

Conclusion: Procalcitonin seems to be an early and specific marker of neonatal sepsis and it is much more sensitive and specific than CRP, IL-6, IL-8, immatur/matur neutrophil ratio to establish neonatal sepsis.
