OBJECTIVES: We determined whether initial antithrombin (AT) levels help in diagnosis and prognosis of neonatal sepsis. METHODS: Sepsis was diagnosed according to clinical and laboratory findings and positive culture results in 34 of the 54 newborns who presented to the hospital with suspected sepsis. Between AT levels and hematological parameters (fibrinogen levels, prothrombin time (PT), activated partial thromboplastin time (aPTT) and liver function tests), these were correlated each other and with outcome of the babies. RESULTS: Initial AT and fibrinogen levels were significantly lower in newborns with sepsis compared to control (P < 0.05). Initial AT levels were lower in the ones who developed disseminated intravascular coagulation (DIC) compared to those without DIC (P < 0.05). Initial AT levels were significantly lower in newborns who died as compared to survivors (P < 0.05). Sensitivity of AT was highest at 15 mg/dL for prognosis in neonatal sepsis (sensitivity:92.3%, specificity:61.9%, positive predictive value : 61.9 %; negative predictive value: 61.9%;). CONCLUSION: Lower initial AT levels in neonatal sepsis are associated with a severe disease and increased mortality. It may be useful in predicting clinical outcome in neonatal sepsis.
