Abstract

Background: Allergic bronchopulmonary aspergillosis occurs in 7-10% of cystic fibrosis (CF) and 1-2% of asthmatic patients. HLA-DR restriction and increased sensitivity to IL-4 stimulation have been proposed as risk factors in these populations.

Objective: We examined for the presence of IL-4 receptor alpha chain (IL-4Ralpha) single nucleotide polymorphisms (SNPs) in ABPA and whether these accounted for increased sensitivity to IL-4 stimulation.

Methods: One extracellular (ile75val) and four cytoplasmic IL-4Ralpha SNPs were analyzed in 40 CF and 22 asthmatic patients and in 56 non-ABPA CF and asthmatic patients. Sensitivity to IL-4 stimulation was measured by induction of CD23 expression on B cells.

Results: IL-4Ralpha SNPs were observed in 95% of ABPA patients. The predominant IL-4Ralpha SNP was the extracellular IL-4Ralpha SNP, ile75val, observed in 80% of ABPA patients.

Conclusion: The presence of IL-4Ralpha SNPs, principally ile75val, appears to be a genetic risk for the development of ABPA.
