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.

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.

regulation in the human lung and measurement of urinary metabolites as biomarkers for. Clinical studies of asthma phenotypes focusing on the role of the leukotrienes vivo stimulation or urinary levels of LTE4 and airway responsiveness to LTD4.

Urinary Leukotriene E-4 and Prostaglandin D-2 Metabolites Increase in Adult and Childhood Severe Asthma Characterized by Type 2 Inflammation A Clinical 

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. BACKGROUND: Urinary leukotriene E4 (ULTE4) may be a biomarker that distinguishes aspirin-intolerant asthma from other asthma subtypes.

Urinary leukotriene asthma

These leukotrienes have received considerable attention for their potential role in asthma and other inflammatory diseases. Jones, K., Wenzel, S. E. (1993) Inactivation of leukotriene C4 in the airways and subsequent urinary leukotriene E4 excretion in normal and …

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.

The aim of this study was to investigate the impact of exercise on the urinary leukotriene profile. 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 (LTE 4).
