Although the researchers do not yet understand why asthma results from reduced production of sphingolipids, their experiments clearly show a link between loss of these lipids and bronchial hyperreactivity
, a key feature of asthma.
physiological studies which show that some AR patients with no perceived asthma develop bronchial hyperreactivity
(BHR) during AR exacerbation, and these are apparently the patients at risk of developing asthma (4), (9), (10);
For example, alcohol consumption has been associated with increased bronchial hyperreactivity
(6) and increased frequency of severe asthma attacks (i.

The degree of bronchial hyperreactivity
(the tendency of the airways to constrict in response to various stimuli) was another significant risk factor for continuing symptoms.
