1在囊性纤维化患儿中中性粒细胞谷氨酰胺缺乏与基因型的关系显示文摘Pulmonary disease in cystic fibrosis (CF) is characterized by a chronic neutrophil-dominated inflammation of lung tissue. Inasmuch as some amino acids (AA) play a pivotal role in various aspects of neutrophil metabolism,the aim of this study was to investigate a possible alteration of neutrophil AA metabolism and to evaluate its relation (if any) with the genotype. We performed plasma and neutrophil AA analysis in 26 CF patients with known genotype,10 patients with non-CF bronchiectasis,and 20 normal subjects. The CF group showed a significant decrease of free intracellular neutrophil glutamine (Gln) content compared with controls and the non-CF bronchiectasis group. In the latter group,levels of neutrophil Gln were significantly lower compared with the controls. Amino acid plasma concentration in non-CF bronchiectasis showed a decrease of Gln and taurine compared with controls. Neutrophil Gln content showed values significantly lower in CF patients with severe mutations (class I,II,and III mutations) compared with mild mutations (class IV and V mutations). Results of our study add further evidence for intrinsic neutrophil alterations that could play an important role in the pathogenesis of chronic pulmonary disease in CF patients.D'Eufemia P.
