    Journal: Allergy; 2005 Jan; 60(1):86-9. PubMed ID: 15575936.
    Abstract:
    BACKGROUND: Leukotrienes are thought to play a role in the pathogenesis of atopic eczema/dermatitis syndrome (AEDS). Urinary leukotriene E4 (U-LTE4) is a marker of whole-body cysteinyl-leukotriene production. AIMS OF THE STUDY: To evaluate the role of leukotrienes in children with AEDS by measuring levels of U-LTE4, and to evaluate whether levels of U-LTE4 may reflect disease activity and allergic sensitization in AEDS. METHODS: U-LTE4 was measured by enzyme-linked immunosorbent assay in 87 children with mild (n=32), moderate (n=34) and severe (n=21) AEDS, as well as in 72 nonatopic healthy controls. Fifty-eight of the children with AEDS were sensitized to common allergens, and 29 were not. RESULTS: Levels of U-LTE4 were higher in children with severe AEDS (140; 66-166 microg/mmol creatinine, median; quartiles) than in controls (52; 30-90, P <0.05), whereas levels of U-LTE4 in moderate and mild disease were similar to controls. U-LTE4 levels were similar in children with or without sensitization to common allergens, but severe AEDS children with sensitization had higher levels of U-LTE4 than those without sensitization. CONCLUSION: The results suggest a role for leukotrienes in the pathogenesis of severe AEDS, and may support a role for leukotriene-antagonists in the treatment of this disorder. Levels of U-LTE4 may reflect the disease severity and sensitization to allergens in AEDS.
