ABSTRACT
To determine serum IL-6, and TNF-alpha and C-reactive protein levels in neonatal sepsis at the time of diagnosis and after therapy, and to show the meaningful on the follow up. This prospective study was performed on newborns who were hospitalized for neonatal sepsis and who were classified as, cultureproven sepsis [n=15], culture-negative sepsis [n=15], healthy newborns [n=15]. At the time of diagnosis, serum IL-6 and TNF-alpha and C-reactive protein levels of culture-proven sepsis were significantly higher than those of the control groups [P<.05]. At the time of diagnosis, IL-6 and TNF-alpha levels of cultureproven sepsis and culture-negative sepsis were significantly higher than levels at the seventh day after antibiotic treatment. Serum IL-6, and TNF-alpha are mediators of inflammation and can be used at the diagnosis and at the evaluation of the therapeutic efficiency in neonatal sepsis
