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. In addition, higher serum levels of IL‐10 were observed in patients colonized with A. fumigatus. These results suggest that polymorphisms in the promoter region of the IL‐10 gene may influence the host response to A. fumigatus in the context of CF.
