Effect of allergen avoidance on development of allergic disorders in infancy
There is much evidence that the development of allergic disorders may be related to early exposure of allergens , including those in breastmilk . We have tried to find out whether avoidance of food and inhaled allergens in infancy protects against the development of  allergic disorders in high-risk infants . In a prenatally r and omised , controlled study 120 infants with family history of atopy and high ( greater than 0.5 kU/l ) cord-blood concentrations of total IgE were allocated r and omly to prophylactic and control groups . In the prophylactic group ( n = 58 ) , lactating mothers  avoided allergenic foods ( milk , egg , fish , and nuts ) and avoided feeding their infants these foods and soya , wheat , and orange  up to the age of 12 months ; the infants ' bedrooms and living rooms were treated with an acaricidal powder and foam every 3 months , and concentrations of Dermatophagoides pteronyssinus antigen(Der p l ) in dust sample s were measured by enzyme-linked immunosorbent assay . In the control group ( n = 62 ) , the diet of mothers and infants was unrestricted ; no acaricidal treatment was done and Der p l concentrations were measured at birth and at 9 months . A paediatric allergy specialist unaware of group assignment examined the infants for allergic disorders at 10 - 12 months . Odds ratios were calculated by logistic regression analysis for various factors with control for other confounding variables . At 12 months , allergic disorders had developed in 25 ( 40 % ) control infants and in 8 ( 13 % ) of the prophylactic group ( odds ratio 6.34 , 95 % confidence intervals 2.0 - 20.1 ) . The prevalences at 12 months of asthma ( 4.13 , 1.1 - 15.5 ) and eczema ( 3.6 , 1.0 - 12.5 ) were also significantly greater in the control group .  Parental smoking was a significant risk factor for total allergy at 12 months whether only one parent smoked ( 3.97 , 1.2 - 13.6 ) or both parents smoked ( 4.72 , 1.2 - 18.2 )
