Influences of neonatal serum IgE concentration, family history and diet on the incidence of XXXX 's @entity6132 .

@entity1 @entity5419 @entity6132 @entity56 @entity291
Serum IgE concentration was measured on the 5th day of life in 943 @entity1 . All @entity1 were included in a 3 month follow-up study. The frequency of @entity291 's @entity6132 was studied according to either family history, IgE level, or both. Feeding (mother's milk or formula feeding) was taken into account. Manifestations suggestive of @entity5419 were hardly observed in breast-fed babies. In the formula-fed group a positive family history correlated with a 40% incidence of @entity56 manifestations, compared to a 13% incidence (P less than 0.001) in the group with negative family history. A high IgE level (IgE greater than 1.3 U/ml) indicated a 43% risk of developing @entity56 manifestations in formula-fed babies as compared to 15% (P less than 0.001) in the group with normal results of a screening test. Frequency of @entity56 manifestations in a subgroup with a negative family history and a high IgE level (38%) was equal to the frequency in the subgroup with a positive family history and negative screening test results (IgE less than 1.3 U/ml)(36%). The incidence in the subgroup with both positive screening test results and a positive family history was 49%. None of these differences were significant. The frequency in the subgroup with both parameters negative was 8% (P less than 0.001 to 3 other subgroups). Our results indicate that the family history seems to correlate as well with the incidence of @entity56 manifestations as the neonatal serum IgE concentration.(ABSTRACT TRUNCATED AT 250 WORDS)
