<p>The aim of this study was to evaluate the predictive value of resistin and visfatin in neonatal sepsis, and to compare these adipocytokines with C-reactive protein (CRP), procalcitonin and interleukin 6 (IL-6).</p><p>A total of 62 term or near term infants with sepsis proven by positivity of blood culture, and 43 healthy infants were included in this study.</p><p>There were no statistically significant differences between the two groups as regards birthweight and gestational age. White blood cell count (p= 0.039), CRP levels (p=0.01), procalcitonin levels (p=0.01), IL-6 levels (p= 0.01), visfatin levels (p=0.01) and resistin levels (p=0.01) were significantly higher in septic infants. There was a positive correlation between visfatin, resistin and other markers (WBC, CRP, procalcitonin and IL-6). A cut-off value of 10 ng/mL for visfatin, showed 92% sensitivity and 94% specificity, and a cut-off value of 8 ng/mL for resistin showed 93% sensitivity and 95% specificity for neonatal sepsis.</p><p>In the light of these results, visfatin and resistin can be used as a diagnostic marker similar to CRP, procalcitonin and IL-6 in neonatal sepsis. Further studies are needed to better understand the role and predictive value of these molecules in neonatal sepsis.</p>
