Asthma in Competitive Cross-Country Skiers: A Systematic

Glossary

zileuton). They have Leukotrienes (LTs), including cysteinyl LTs (CysLTs) and LTB4, are potent lipid mediators that are pivotal in the pathophysiology of asthma phenotypes. At Cysteinyl leukotrienes are pro-inflammatory substances that cause asthma by narrowing the airways of the lung. The investigators want to see if subjects with increased fat stores and therefore increased leptin, which is a fat-related protein that regulates leukotrienes, have increased levels of leukotrienes in the blood, lung and urine. Summary Leukotrienes are clearly involved in airway inflammation and certain clinical features of asthma. Evolving evidence indicates that leukotriene B 4 has an important role in the development of asthma and that cysteinyl leukotrienes are key mediators of the airway remodeling process. Clinical studies of asthma phenotypes focusing on the role of the leukotrienes.

The cysteinyl LTs are potent bronchoconstrictors, which have additional effects on blood vessels, mucociliary clearance and eosinophilic inflammation. Leukotrienes play a key role in asthma in three ways: causing inflammation, bronchoconstriction and mucus production. The cysteinyl leukotrienes (LTC 4, LTD 4 and LTE 4) have been shown to be the most potent bronchconstrictors in humans and are believed to play a crucial role in asthmatic airway obstruction. Leukotrienes are thought to play a central role in the bronchoconstriction, edema formation, and increase in mucus production associated with the symptoms of asthma.

While β2‐agonists are often used for short‐term relief of acute bronchospasm, anti‐inflammatory agents are required for th leukotrienes. Leukotrienes play a key role in asthma in three ways: causing inflammation, bronchoconstriction and mucus production. The cysteinyl leukotrienes (LTC 4 , LTD 4 and LTE 4 ) have been shown to be the most potent bronchconstrictors in humans and are believed to play a crucial role in asthmatic airway obstruction. The cysteinyl leukotrienes (CysLT), LTC 4, LTD 4, and LTE 4, have been shown to be essential mediators in asthma, making them obvious targets for therapy.

Leukotrienes have a number of effects that lead to the production of asthma symptoms. First, they promote bronchiole constriction leading to narrowing of the airways.
