Abstract
Sputum samples from 13 children with cystic fibrosis (CF) were analyzed for leukotrienes (LTs) LTB4, LTC4, LTD4, and LTE4. Distribution of LTB4 appeared to be normal, and of cysteinyl-LTs log normal. Total cysteinyl-LT levels, of which on average 75% was LTE4, were nearly 10 times higher than in earlier studies. Log LTE4 and total cysteinyl-LT levels correlated with the overall severity of pulmonary disease assessed by Chrispin-Norman chest radiograph score (Log LTE4: r = 0.701, r2 = 49.1%, P = 0.008. Log total cysteinyl-LTs: r = 0.715, r2 = 51.1%, P = 0.006). There was no apparent relationship between LTB4 levels and Chrispin-Norman chest radiograph score, nor between the level of any of the LTs and age or organism cultured from sputum. These findings suggest that the cysteinyl-LTs may be involved in the pathophysiology of pulmonary disease in CF.
