Abstract

Airway inflammation can be studied by obtaining sputum induced by inhalation of 3% saline. The Sensormedics MCT accelerator is an oral asymmetrical high frequency oscillator which safely enhances clearance of airway secretions. The aim of this study was to determine if use of the MCT Accelerator enhances sputum production in non-asthmatic non-atopic, atopic and asthmatic subjects. Fifteen subjects were studied over 3 days. On day 1 skin prick testing to common aeroallergens and methacholine bronchial reactivity were performed. On days 2 and 3, separated by 7 days, sputum was induced by inhalation of 3% saline alone for 30 mins or via the nebulizer port of the MCT Accelerator. The cellular profile and volume of sputum were analysed. The use of the MCT Accelerator did not alter the cellular profile of the induced sputum nor was there an increase in volume. In conclusion the induction of sputum by inhalation of 3% saline was not altered by use of the MCT Accelerator.

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.

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. Discover the latest research on atopic dermatitis 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.
