Intestinal permeability in irritable bowel syndrome. Effect of diet and sodium cromoglycate administration

Abstract

We studied 14 patients with irritable bowel syndrome for the presence of increased intestinal permeability to food antigens and their responses to diet with and without disodium cromoglycate. After a standardized oral challenge with cow milk, serum beta-lactoglobulin was increased above control values in three patients. This finding did not correlate with response to hypoallergenic diet or treatment with disodium cromoglycate for 3 weeks. However over 50% of patients improved after diet with and without DSCG (2/5 on diet only and 5/7 with disodium cromoglycate of 12 evaluable cases). Since only two patients had elevated serum IgE levels, our results suggest that intolerance rather than hypersensitivity to foods may play a role in the disease. The tests we used to identify immunologic mechanisms could not predict which patients would do better on the diet and/or the drug.

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.

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.
