| Popis: | We studied 57 low-birth-weight premature neonates, of whom 29 suffered from perinatal asphyxia and/or infection, while the remaining 28 did not and served as controls. We measured peripheral nucleated red blood cell (NRBC) absolute numbers as well as interleukin (IL)-1beta, IL-6 and tumour necrosis factor (TNF)-alpha cytokine serum levels at 24 h postnatally and on days 3 and 7 following birth. Fourteen of the asphyxiated/infected neonates and 12 controls had neurologic assessments at the corrected postnatal age of 18 months. We found NRBC absolute numbers and serum IL-1beta and IL-6 cytokine levels at 24 h postnatally to be significantly higher in neonates with perinatal asphyxia/infection than in the controls (p = 0.022, p = 0.036 and p = 0.037, respectively). TNF-alpha levels did not differ. Neurologic examination at the corrected postnatal age of 18 months showed 8 out of the 14 children who had been asphyxiated/infected as neonates to have abnormal findings, while 12 children who were used as controls during their neonatal period were normal. Abnormal neurologic findings correlated with high NRBC counts and IL-1beta and IL-6 levels at 24 h postnatally. In conclusion, increased NRBC counts and proinflammatory cytokine levels in asphyxiated/infected neonates represent early markers for subsequent neurologic impairment. |
