17 18 Several studies in adults and children have reported increased levels of leukotrienes in acute asthma that fall as the attack resolves. 16 While existing studies have focused on the use of the LTRAs in chronic asthma, the findings in the paper by Dockhorn et al raise the possibility that leukotriene inhibition may also be beneficial in acute asthma. Blood levels of leukotrienes (LTC4, D4, E4, B4) in asthmatic patients during attack and remission. To assess the contribution of the leukotrienes, LTC4, D4, E4 and B4 during bronchial asthma attacks, simultaneous determination was made of their levels in venous blood. 25 patients with bronchial asthma (15 atopic types, 10 non-atopic types) mediators in asthma, making them obvious targets for therapy. These cysteinyl leukotrienes, previously known as the slow-reacting substance of anaphylaxis (SRS-A), mediate many of the features of asthma, including bronchial constriction, bronchial hyperreactivity, edema, and eo-sinophilia.

The relationship between leukotrienes and asthma is one of cause and effect. Antigens, foreign substances like dust and pollen, usually bring on asthma attacks. It is leukotrienes, however, that trigger the biological response that sets in motion an asthma attack.

2021-04-23 · The results indicate that in symptomatic asthma there is a continual generation of cysteinyl-leukotrienes within the airway and this has been further supported by studies with zileuton, which again demonstrated that when administered acutely, there is an improvement in pulmonary function within 1 h of ingestion (10). Leukotrienes are very important agents in the inflammatory response. Some such as LTB 4 have a chemotactic effect on migrating neutrophils, and as such help to bring the necessary cells to the tissue. Leukotrienes also have a powerful effect in bronchoconstriction and increase vascular permeability.
