Abstract
To show whether neonatal eosinophil counts (EC) and eosinophil cationic protein (ECP) can be used in assessing the risk of atopy, alone or in combination with family history of atopy (FHa). A group of 63 newborns was included: 38 with FHa, 25 without FHa. A blood sample was collected on the 4th day of life for EC and ECP evaluation. Clinical follow-up was conducted after 1, 3, 6, 12, 18, 24 and 36 mo. The chi2 test and the Student's t-test were used to compare dichotomic and continuous variables, respectively. Variables shown to be significant by univariate analysis were evaluated with a multivariate regression model and the relative risks (RR) were estimated. Twenty-six newborns (41%) displayed atopic manifestations during the follow-up. Twenty-one (55%) of 38 newborns with FHa displayed atopic symptoms versus 5/25 (20%) without FHa (p 0.012). Neither EC nor serum ECP levels were significantly different between newborns with FHa and newborns without. ECP levels did not differ between newborns with single heredity and newborns with dual heredity. EC did not differ significantly between newborns who developed atopy and those who did not. Instead, serum ECP levels were significantly higher in newborns who developed atopy (mean 27...Continue Reading
