Amongthese products are the lipid media-tors cysteinyl leukotrienes (leukotriene C4 (LTC4), leukotriene D4 (LTD4), and leukotriene E4 (LTE4)), which abundant evi-dence implicates in airflow obstruction in asthma.2 They are potent inducers of bron-choconstriction,3 mucus hypersecretion,4 and airwayoedema.5LTE4concentrations, usedas

However, an overlap between the individual values of the groups exists. Objective: The objective of this study was to estimate the discriminative value of uLTE 4 concentration in differentiating between patients with AERD and patients with ATA and evaluate the Urinary LTE4, was extracted using C18 solid phase column and measured by radioimmunoassay. There was no significant difference in urinary LTE4 levels among asthmatics with different severity or between atopic and non-atopic asthmatics. Urinary LTE4 levels were significantly elevated in asthmatics compared with normal controls (p < 0.05). While leukotrienes play an important role in chronic asthma, activation of the leukotriene pathway in acute asthma is less well defined.

Keywords: Asthma / Physiopathology Board Subjects: Child ,Bronchial Hyperreactivity ,Leukotriene E4 ,Urine ,Respiratory Function Tests ,Prognosis , Urinary leukotriene E[4]in asthmatic children with and without nocturnal exacerbations, J. Pediatr. Club Background Aspirin challenge of aspirin‐intolerant asthma (AIA) patients causes a significant increase in leukotriene E 4 (LTE 4) concentration in urine. However, knowledge on leukotriene B 4 (LTB 4 ) generation in patients with AIA is insufficient. The leukotrienes LTC4, D4, and E4 are potent bronchoconstrictor agents and are thought to have an important role in asthma.

The relationship between urinary LTE 4 levels and factors associated with acute asthma has not been determined. Methods: Adults aged 15–54 years presenting with moderate to severe acute asthma were evaluated at emergency departments in 16 US sites. Urinary LTE4, was extracted using C18 solid phase column and measured by radioimmunoassay. There was no significant difference in urinary LTE4 levels among asthmatics with different severity or between atopic and non-atopic asthmatics. Urinary LTE4 levels were significantly elevated in asthmatics compared with normal controls (p < 0.05).

LTE4 excretion followed a log-normal distribution in twenty-nine healthy controls, with a geometric mean of 23·8 (95% Fig. 1. Time course of allergen-induced early- and late-phase bronchoconstriction (top) and urinary excretion of LTE 4 in 12 subjects with atopic asthma (bottom).Pulmonary function is expressed as percentage of post-diluent FEV 1 and urinary LTE 4 is expressed as nanograms per millimole of creatinine, and both were monitored up to 24 h after allergen inhalation. Plasma cysteinyl leukotrienes were low or undetectable, but urinary leukotriene E4 (LTE4) was higher in the asthmatics during an acute episode (210 pmol/mmol creatinine, 101 to 454) and at follow up (179 pmol/mmol, 110 to 293), compared with the normal children (98 pmol/mmol, 81 to 118, n = 41). Urinary leukotriene excretion profile in children with exercise-induced asthma compared with controls: A preliminary study. Allergologia et Immunopathologia, 2012. J. … Recent evidence suggests that the cysteinyl-leukotrienes (LTC4, LTD4, and LTE4) may be important in the pathogenesis of exercise-induced asthma.
