Recent evidence suggests that the cysteinyl-leukotrienes (LTC4, LTD4, and LTE4) may be important in the pathogenesis of exercise-induced asthma. To evaluate the role of these mediators further, nin

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. Urinary LTE4, a stable urinary end-product of LTC4 and LTD4, was measured, by means of high-performance liquid chromatography and radioimmunoassay. 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).

Arch Dis Child. Cigarette smoking is associated with increase urinary leukotriene (LT)E 4 production in healthy subjects in some (6), but not in all studies (7), in smokers with asthma compared with nonsmokers Patients with aspirin sensitive asthma (ASA) can be desensitized to aspirin but the mechanisms by which this happens are unknown. To test the hypothesis that there may be a reduction in aspirin-induced leukotriene release following aspirin desensitization, we studied nine patients with ASA, 37 +/- 2.3 yr of age (mean +/- SEM) with a baseline FEV1 of 94 +/- 3.5%. Objective. The goal of this study was to evaluate the impact of urinary leukotriene E 4 (ULTE 4) in asthmatic children during acute asthma exacerbation.Also, we wanted to correlate it with the total serum (TS) immunoglobulin (Ig) E level in relation to asthma severity. Background: Leukotrienes play a key role in the pathophysiology of chronic asthma. Activation of leukotriene pathways is accompanied by rises in detectable urinary levels of leukotriene E-4 (LTE4).

Therefore, medicines that are largely excreted in the urine should be administered As the asthma disease varies in intensity over time, treatment should be OR LEUKOTRIENE RECEPTOR ANTAGONIST First-Line Treatment budesonide

Eosinophil protein X (EPX) has been used to assess eosinophil activity and monitor inflammation in bronchial asthma. The aim of the study was to look for differences in urinary LTE4 and EPX concentrations between children with stable atopic Fig. 1.

Background: Patients with aspirin-exacerbated respiratory disease (AERD) are distinguished from patients with aspirin-tolerant asthma (ATA) by significantly higher baseline concentrations of urinary leukotriene E 4 (uLTE 4 ). 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.
