Abstract

Food allergy (FA) is associated with an increased risk of asthma. To evaluate whether bronchial hyperreactivity (BHR) occurs in children with FA depending on the presence of respiratory symptoms. Fifty-four children with FA and 62 without FA were studied for BHR, defined as a provocation concentration of methacholine that caused a decrease in forced expiratory volume in 1 second of 20% (PC20). The diagnosis of FA was established using questionnaires, clinical criteria, skin prick tests, serum specific IgE antibodies, and a double-blind placebo-controlled food challenge. Among nonasthmatic children, BHR was diagnosed in 15 (47%) with FA and in 7 (17%) without FA (P < .005); BHR was demonstrated in 7 children (41%) with FA alone. All the patients with asthma with or without FA had BHR. The mean (SD) PC20 in children with FA alone was 2.8 [1.38] mg/mL and was significantly higher than that in children with asthma alone (0.88 [1.01] mg/mL) or with asthma and FA (0.96 [0.83] mg/mL) (P < .001). BHR was detected in 5 children (36%) with a mild anaphylactic reaction provoked by food, in 23 (74%) with a moderate reaction, and in all the children with a severe reaction. Children with FA had increased BHR independent of respiratory sympto...Continue Reading

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. Discover the latest research on atopic dermatitis here.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
