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.

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.

The sulphidopeptide leukotrienes (LTC 4, LTD 4 and LTEJ comprise the activity previously referred to as the slow reacting substance of anaphylaxis (SRS-A). These Leukotriene E4 (LTE4) and 11-dehydrothromboxane B2 (11DTXB2) values in spot urine were measured in 22 asthmatics with a history of aspirin sensitivity and in 17 without such a history (non-aspirin-sensitive asthma [NASA]) in the outpatient clinic. The urinary LTE4 values were log-normally distributed.

BACKGROUND Urinary leukotriene E4 (LTE4) is a marker of the body's production of cysteinyl LTs, important mediators of airway inflammation. The role of the latter in nocturnal asthma is a topic of increasing interest. OBJECTIVE This investigation was aimed at determining whether nighttime attacks are associated with increased release of LTs, expressed by urinary LTE4, and the relationship Urinary Leukotriene E 4 and Prostaglandin D 2 Metabolites Increase in Adult and Childhood Severe Asthma Characterized by Type 2 Inﬂammation A Clinical Observational Study Johan Kolmert 1,2,3,CristinaG´omez 1,2,3, David Balgoma , Marcus Sj¨odin , Johan Bood1,3,4,JonR.Konradsen3,5,6, Study of urinary leukotriene E4 levels in children with acute asthma Ghada Saad Abd El-Motaleb,1 Alraohaa Ahmed Ahmed Abou Amer,1 Gamal Mohamed Elawa,2 Mohamed Abo Alsood Abd Elfattah3 1Department of Pediatrics, 2Department of Clinical Pathology, Faculty of Medicine, Benha University, Benha, Qalyubia, Egypt; 3Department of Pediatrics, Ministry of Health Hospital, Cairo, Egypt Objective: … Urinary Leukotriene E4 Levels after Allergen and Exercise Challenge in Bronchial Asthma 1- 3 CHRISTINE M.
