IL-6 and IL-10 levels in the umbilical cord blood of newborns with a history of crack/cocaine exposure in utero: a comparative study.

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.
