INTRODUCTION: Prenatal cocaine exposure (PCE) is associated with neurobehavioral problems during childhood and adolescence. Early activation of the inflammatory response may contribute to such changes. Our aim was to compare inflammatory markers (IL-6 and IL-10) both in umbilical cord blood and in maternal peripheral blood at delivery between newborns with history of crack/cocaine exposure in utero and non-exposed newborns.
METHODS: In this cross-sectional study, 57 newborns with a history of crack/cocaine exposure in utero (EN) and 99 non-exposed newborns (NEN) were compared for IL-6 and IL-10 levels. Sociodemographic and perinatal data, maternal psychopathology, consumption of nicotine and other substances were systematically collected in cases and controls.
RESULTS: After adjusting for potential confounders, mean IL-6 was significantly higher in EN than in NEN (10,208.54, 95% confidence interval [95%CI] 1,328.54-19,088.55 vs. 2,323.03, 95%CI 1,484.64-3,161.21; p = 0.007; generalized linear model [GLM]). Mean IL-10 was also significantly higher in EN than in NEN (432.22, 95%CI 51.44-812.88 vs. 75.52, 95%CI 5.64-145.39, p = 0.014; GLM). Adjusted postpartum measures of IL-6 were significantly higher in mothers with a history of crack/cocaine use (25,160.05, 95%CI 10,958.15-39,361.99 vs. 8,902.14, 95%CI 5,774.97-12,029.32; p = 0.007; GLM), with no significant differences for IL-10. There was no correlation between maternal and neonatal cytokine levels (Spearman test, p ≥ 0.28 for all measures).
CONCLUSIONS: IL-6 and IL-10 might be early biomarkers of PCE in newborns. These findings could help to elucidate neurobiological pathways underlying neurodevelopmental changes and broaden the range of possibilities for early intervention.
