The Heiner syndrome serves as a model of milk-protein induced pneumonitis associated with hemosiderosis. They suggested a Type III mechanism and reviewed the alveolitis in celiac disease. Chronic coughs may mean allergic bronchitis with or without asthma. Food allergy patients are often given antibiotics repeatedly, since allergic symptoms and infection symptoms are similar. Antibiotics may offer no benefits and may increase the risk of further allergic reactions.
Many patients report long-term deterioration after repeated or prolonged antibiotic use.
This apparent adverse effect of antibiotics has been blamed on yeast overgrowth in GIT, but the real reason is probably more complex. Food allergens travel from the digestive tract to the lungs. Food allergens may be found in the blood stream in circulating immune complexes that trigger the release of immune mediators in the bloodstream. Airflow is reduced in the narrowed tubes. Air has a harder time leaving the lungs than entering-the result is prolonged noisy expiration.
