Abstract

A group of forty-two steroid-dependent perennial asthmatics was studied over a 13-week period incuding the 8 weeks of a double-blind controlled trial of oral sodium cromoglycate. Given at a dose of 200 mg four times per day the drug provided no significant benefit to the patients when compared with results for those on placebo. Blood from eleven patients consistently failed to release more than 25% of the total cellular histamine when challenged with a range of concentrations of antibody to IgE. All six of the cryptogenic (intrinsic) asthmatics in the trial fell within this group, together with 2/12 asthmatics with negative skin tests but suggestive clinical histories implicating common alergens, and 3/24 extrinsic asthmastics with positive skin prick tests. There was no correlation between drug usage and histamine release in response to challenge with antibody to IgE.

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.
