Aspergillus fumigatus in cystic fibrosis: an update on immune interactions and molecular diagnostics in ABPA

Abstract

A wide spectrum of pathological conditions may result from the interaction of Aspergillus fumigatus and the immune system of its human host. Allergic bronchopulmonary aspergillosis is one of the most severe Aspergillus fumigatus-related diseases due to possible evolution towards pleuropulmonary fibrosis and respiratory failure. Allergic bronchopulmonary aspergillosis occurs almost exclusively in cystic fibrosis or asthmatic patients. An estimated 8 to 10% of cystic fibrosis patients experience this condition. The diagnosis of allergic bronchopulmonary aspergillosis relies on criteria first established in 1977. Progress in the understanding of host-pathogen interactions in Aspergillus fumigatus and cystic fibrosis patients and the ongoing validation of novel laboratory tools concur to update and improve the diagnosis of allergic bronchopulmonary aspergillosis.
