EXERCISE-INDUCED ASTHMA: RESEARCHING PREDICTORS IN SUBJECTS WITH MILD ASTHMA

Exercise-induced asthma: the "silent asthma".

Refractoriness to inhaled sodium metabisulphite in subjects with mild asthma.

Refractoriness occurs after challenges causing mediator release in asthma, by a mechanism which may involve inhibitory prostaglandins. Bronchoconstriction due to inhaled sodium metabisulphite is thought to involve neural pathways and to be independent of mediator release; whether it shows refractoriness is uncertain. We have sought evidence of refractoriness to the bronchoconstrictor response t...

Exercise-induced asthma.

A review of exercise-induced asthma is presented which describes work that has been carried out by the authors and by other investigators over recent years. The effect of exericse on lung function in asthmatic and normal subjects is compared. The influence of the type and severity of exercise on the response of the asthmatic is noted and the importance this has for interpretation of results. Th...

[Exercise-induced asthma].

All asthmatics have exercise-induced asthma (EIA). In periods where the asthma spontaneously deteriorate, there will be more exercise-induced asthma. About 3/4 of the asthmatics will have a positive exercise test on the first challenge. Exercise is not the best test to obtain the diagnosis of asthma, as other tests, e.g. inhalation of histamine, is more sensitive and specific. The best pretreat...

Exercise-induced asthma in children.

"If from running, gymnastic exercises, or any other work, the breathing becomes difficult, it is called Asthma (<XmJlCX)". Aretaeus the Cappodician; lst Century AD [1]. Exercise-induced bronchoconstriction (EIB) was long ago recognized as a manifestation of asthma [1], and exercise-induced asthma (EIA) is a common presentation of childhood asthma. BACKER and ULRIK [2] reported that 16% of 494 h...
