Abstract | BACKGROUND: Eosinophils play an important role in allergic responses. Eotaxin is a CC chemokine that promotes the selective recruitment of eosinophils. This study was performed to investigate the significance of eotaxin in pediatric food allergies. METHODS: RESULTS: Plasma eotaxin-1 levels were 93.6+/-33.4 pg/ml in patients with food allergy, 78.0+/-31.8 pg/ml in patients with atopic dermatitis, and 60.4+/-15.7 pg/ml in controls. Differences between the food allergy and control groups were significant (P<0.001). Circulating eosinophil counts in patients with food allergy were higher than those in controls (5.84+/-9.46x10(9)/l vs. 1.20+/-1.11x10(9)/l, P<0.001). Nevertheless, eotaxin-1 levels in children with food allergy were not correlated with eosinophil counts or serum IgE levels. There were no significant differences in eotaxin-3 levels between the 3 groups. CONCLUSION: Plasma levels of eotaxin-1 were elevated in children with food allergy. The pathophysiological relevance of the increase in eotaxin is discussed.
