Abstract

Cysteinyl leukotriene (CysLTs) plays an important role in airway inflammation and remodeling in asthma. Measurement of urinary leukotriene E(4) (LTE(4)) is a sensitive and noninvasive method of assaying total body CysLTs level. This study aimed to evaluate the clinical significance of urinary leukotriene E(4) (LTE(4)) in childhood asthma. Sixty children with acute asthma were randomly divided into montelukast (leukotriene receptor antagonist) treatment and conventional treatment groups (n = 30 each). Urinary LTE(4) levels were measured using ELISA and the airway resistance Rint was assessed by the lung function instrument at the acute and the convalescence phases. Twenty healthy children were used as the control group. Urinary LTE(4) levels in asthmatic children at the acute and the convalescence phases were significantly higher than those in the control group (p<0.01). The urinary LTE(4) levels at the convalescence phase were significantly reduced compared with those at the acute phase in asthmatic children (p<0.01). More significantly decreased urinary LTE(4) levels were noted in the montelukast treatment group than the conventional treatment group at the convalescence phase (p<0.01). In the acute phase, there was no correlat...Continue Reading

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
