In allergic disorders, measurement of immune mediators in the urine has expanded our understanding of pathogenesis, as exemplified by the report of O'Sullivan et al . in this issue of the BACKGROUND: Urinary leukotriene E4 (ULTE4) may be a biomarker that distinguishes aspirin-intolerant asthma from other asthma subtypes. OBJECTIVE: To estimate the diagnostic testing accuracy of ULTE4 as a marker of aspirin intolerance in patients with asthma using previously published studies. A group of 17 patients with allergic asthma was challenged with aerosolized antigen, and the excretion of the peptidoleukotriene metabolite leukotriene (LT) E4 in the urine was determined as an index of leukotriene synthesis. The allergen challenge caused a drop in FEV1 of 25 to 59% within the first 2 h in all patients.

Activation of leukotriene pathways is accompanied by rises in detectable urinary levels of leukotriene E 4 (LTE 4). The relationship between urinary LTE 4 levels and factors associated with acute asthma has not been determined. 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). Results: The mean urinary LTE4 excretion rate was 83.8 +/- 38.2 pg/mg creatinine (mean +/- SD) in normal subjects; in patients with asthma, the urinary LTE4 excretion rate (110.0 +/- 59.2 pg/mg creatinine) was significantly higher than that in normal subjects (p < 0.05). The urinary histamine excretion rate was not different between normal subjects (24.0 +/- 12.5 ng/mg creatinine) and patients with asthma (31.5 +/- 25.8 ng/mg creatinine).

Their release by alIergen or other challenge has been demonstrated in the lungs of asthmatic subjects, and measurement of urinary leukotriene concentrations The use of leukotriene receptor antagonists (LTRAs) as complementary therapy in asthma.

Thus measurement of urinary LTE4 may predict the degree of airflow obstruction in asthmatic children. Urinary LTE4 and EPX are useful markers of airway inflammation and can be helpful in guiding asthma management. study of urinary leukotriene e 4 levels in children with acute asthma Ghada saad abd el-Motaleb1 alraohaa ahmed ahmed abou amer1 Gamal Mohamed elawa2 Mohamed abo alsood abd elfattah3 BACKGROUND Urinary leukotriene E4 (LTE4) is a marker of the body's production of cysteinyl LTs, important mediators of airway inflammation.

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.

The aim of the study was to look for differences in urinary LTE4 and EPX concentrations between children with stable atopic 2019-04-18 Urinary LTE 4 levels had a circadian variation in patients with nocturnal asthma; however, this was not the case in patients with nonnocturnal asthma, suggesting that LTs might be important in the pathogenesis of nocturnal asthma. Circadian rhythm of urinary 11-dehydro-TXB 2 with morning acrophase was observed in both nocturnal and nonnocturnal Study of urinary leukotriene E4 levels in children with acute asthma . In this study, 63 children with acute asthma exacerbation (group I) and 25 healthy children as the control (group II) were included. Their ages ranged between 3–14 years.
