An elimination diet for chronic urticaria of childhood.
Twenty-three children with chronic urticaria were treated with an elimination diet for two weeks. Eighteen completed the period of dietary elimination; in seven of the 18 children there was a marked remission of the urticaria during the second week of the diet. The administration of challenge capsules provoked an exacerbation of urticaria in five of the 14 (36%) children given aspirin. The incidence of reactions to tartrazine, sodium benzoate and yeast (7%) was not significantly different from those to the lactose placebo (9%). In selected cases, elimination diets with controlled reintroduction of foods have a role in the management of chronic urticaria in childhood.
