Abstract

Objective Periventricular leukomalacia, a common brain white matter lesion in preterm neonates, is a major risk factor for cerebral palsy. Recently, cytokines (i.e., tumor necrosis factor and interleukin-1(beta)) have been implicated as mediators for the development of periventricular leukomalacia. The purpose of this study was to examine the relationship between umbilical cord plasma levels of tumor necrosis factor-alpha, interleukin-1(beta), interleukin-6, and interleukin-1 receptor antagonist and the occurrence of periventricular leukomalacia in preterm neonates.Study design Umbilical cord blood was collected from 172 consecutive preterm births (25 to 36 weeks). Periventricular leukomalacia-associated lesions were diagnosed by brain ultrasonography within the first 3 days of life. Tumor necrosis factor-alpha, interleukin-1(beta) interleukin-6, and interleukin-1 receptor antagonist were measured by sensitive and specific enzyme-linked immunoassay methods. Umbilical cord arterial pH was measured at birth. Statistical analysis was performed with multiple logistic regression and receiver operating characteristic curve analysis.Results Periventricular leukomalacia-associated lesions were present in 14.5% (25/172) of infants. Plasma concentrations of interleukin-6 but not of tumor necrosis factor-alpha, interleukin-1(beta), and interleukin-1 receptor antagonist were significantly higher in neonates with periventricular leukomalacia-associated lesions than in those without these lesions (median 718, range < 226 to 32,000 pg/ml vs median < 226, range < 226 to 43,670 pg/ml; p < 0.0001). An interleukin-6 value > or = 400 pg/ml had a sensitivity of 72% (18/25) and a specificity of 74% (108/147) in the identification of periventricular leukomalacia-associated lesions. Multivariate analysis showed that umbilical cord interleukin-6 was an independent risk factor for periventricular leukomalacia (odds ratio 6.2, p < 0.002) after correction for known confounding variables (i.e., gestational age at birth, umbilical artery pH, chorioamnionitis).Conclusions Interleukin-6 concentrations in umbilical cord plasma are elevated in neonates with periventricular leukomalacia-associated lesions. Our data support the hypothesis that periventricular leukomalacia may be the result of cytokine-mediated brain injury.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
