Food Allergies May Trigger Life-Threatening Asthma Attacks

Food Allergies May Trigger Life-Threatening Asthma Attacks

Sunday, June 15th 2003

Food allergies may trigger life-threatening asthma attacks, according to results of a case-controlled study published in the July issue of the Journal of Allergy and Clinical Immunology (JACI) and released early on the JACI Web site. Half of children hospitalized for asthma had food allergies, especially to peanuts, compared with 10% of controls.

"This study stresses the importance of detailed allergy investigations in asthmatic children," senior author Gideon Lack, MD, from St. Mary's Hospital in London, U.K., says in a news release. "This should allow pediatricians to identify a group of children at risk for severe reactions and the potential cause for severe asthma in certain children."

The investigators compared a group of 19 children admitted to a pediatric intensive care unit and dependent on ventilators because of respiratory failure after an asthma attack with a group of 38 children with milder asthma. Evaluation included spirometry, skin prick or RAST testing for food allergy, and a questionnaire reviewing exposure to food allergens 24 hours before the asthma attack.

Risk factors for life-threatening asthma were food allergy (odds ratio [OR], 8.58; 95% confidence interval [CI], 1.85 - 39.71), multiple allergic diagnoses (OR, 4.42; 95% CI, 1.17 - 16.7), early onset of asthma (OR, 6.48; 95% CI, 1.36 - 30.85), and frequent hospital admissions (OR, 14.2; 95% CI, 1.77 - 113.59).

Regression analysis revealed that the only independent risk factors for life-threatening asthma were frequent hospital admissions with asthma (OR, 9.85; 95% CI, 1.04 - 93.27) and food allergy (OR, 5.89; 95% CI, 1.06 - 32.61).

Half of the children with life-threatening asthma had food allergies, especially to peanuts, compared with 10% of the children in the control group. The investigators suggest that life-threatening asthma attacks may therefore be triggered by food allergies.

"More intensive management of this group may decrease the morbidity and mortality associated with their asthma," Dr. Lack says.
