چکیده
the identification of early markers of atopy in cord blood of newborns at delivery may offer prediction of future allergic sensitization. the aim of this study was to evaluate the relationship between cord blood interleukin-13 (il-13) and interferon-gamma (ifn-γ) and development of allergic diseases during the first five years of life. umbilical cord blood samples were collected at the time of delivery from 62 newborns. the families of these newborns were asked to complete a questionnaire about age and education of parents, number of siblings, allergic diseases in family members, cigarette exposure during pregnancy and presence of pets in their house. the same subjects were evaluated when they were five years old. venous blood samples were drawn and epidermal skin prick tests were performed. il-13 and interferon-gamma (ifn-γ) levels were studied from the blood samples which were taken during birth and five years later. there was no significant relationship between gender, type of delivery, educational levels of parents, exposure to cigarette smoke, atopy in parents, presence of pets in the house and il-13 and ifn-γ levels in cord blood and at five years. higher levels of il-13 in newborns and five years olds, were found significantly related to skin prick test positivity (p=0.004 and p<0.0001, respectively) and presence of allergic diseases (p= 0.008 and p= 0.001, respectively). levels of ifn-γ, both in cord blood and five years after, were not related with the future of allergic status of children. higher levels of il-13 in cord blood may be a predictor of future development of allergic sensitization.
