Influence of interleukin-10 on Aspergillus fumigatus infection in patients with cystic fibrosis.

Recent evidence suggests that genetic polymorphisms that affect the production of interleukin (IL)-10 may play a role in the response to pathogens in cystic fibrosis (CF). The present study was designed to investigate a possible association between alleles carried at position -1082 in the promoter region of the IL-10 gene and clinical data on 378 patients with CF. After adjustment for potential confounding variables, a significant relationship was found between the -1082GG genotype and both colonization with Aspergillus fumigatus and allergic bronchopulmonary aspergillosis.
