RESUMO
Neonatal sepsis is one of the major causes of morbidity and mortality in neonates. Proper diagnosis and management of neonatal septicemia can markedly affect prognosis of neonatal sepsis. In sepsis serum pro-Adrenomedullin level [pro-ADM] was known to be increased while Anti thrombin is rapidly depleted as a result of decreased synthesis, increased destruction, and enhanced clearance. The aim of this study was to clarify the prognostic value of serum Pro-ADM and Anti thrombin level in neonatal sepsis. 40 full term neonates with sepsis were enrolled in this study including 20 cases with mild sepsis and 20 cases with severe sepsis. They were admitted to the neonatal intensive care unit, they included 26 males and 14 females with a mean birth weight of 3.2 +/- 0.26 kg. Twenty healthy full term neonates of matched age and sex served as a control group. Serum levels of Pro ADM and Antithrombin were measured in all patients and control group. Serum Pro ADM level was significantly higher in neonates with sepsis than control group, was significantly higher in severe than mild sepsis and was significantly higher in the unsurvived cases. Antithrombin concentrations were significantly lower in neonates with sepsis than control group, significantly lower in severe than mild sepsis and significantly lower in neonates with sepsis who died than who survived. In conclusion, higher pro-ADM and lower initial AT levels in neonatal sepsis are associated with severe disease and increased risk of mortality
