Summary
Sensitisation to fungi has been reported to play an important role in a particular phenotype of severe asthma, the so-called severe asthma with fungal sensitisation, characterised by high levels of total IgE, which may be an obstacle to anti-IgE therapy. We describe here the case of a polysensitised woman with refractory asthma, sensitised to Aspergillus fumigatus with high total IgE values (1793 kUA/l), but without the diagnostic criteria for allergic bronchopulmonary aspergillosis. Additional therapy with itraconazole leads to the decrease of total IgE to the limits recommended for proper omalizumab dosing (30–1500 kUA/l). Itraconazole, used as bridge therapy, provided us the opportunity to start anti-IgE treatment in a patient with high levels of total IgE, beyond the upper limits recommended for proper prescription of omalizumab.
