Abstract

Atopic asthma is a chronic inflammatory disorder of the airways associated with airway hyperresponsiveness to various bronchoconstrictor stimuli. There are several pharmacologic agents, involved in the inflammatory process, that can produce acute bronchoconstriction, such as metacholine. Heparin possesses multiple noncoagulant properties, including anti-inflammatory actions. The purpose of the present study was to investigate the effect of inhaled heparin on the airway response to metacholine in children with asthma. Fifteen children with mild atopic asthma participated in the study. It was randomized, double-blind, cross-over, placebo controlled study. There were three study visits. At the first visit patients were included into the study and beta-agonists were withheld for at least 12 hours before the next visit (second day). At the second visit provocation test with metacholine, inhalation with single dose of heparin or placebo followed by provocation test with metacholine were performed. After two weeks, tests were performed in the same manner except of that patients instead of heparin inhaled placebo or opposite. Fourteen children completed the study. Single dose of inhaled heparin significantly decreased bronchial hyperre...Continue Reading

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.

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.

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.
