Aspergillus fumigatus can cause a variety of pulmonary syndromes including allergic bronchopulmonary aspergillosis (ABPA), chronic pulmonary aspergillosis and invasive pulmonary aspergillosis (IPA). Occurrence of IPA and ABPA in the same patient is rare as the risk factors for ABPA and IPA are different. We describe a 45-year-old male with ABPA treated with oral methylprednisolone and itraconazole, who developed acute respiratory failure secondary to IPA, a month later. The patient subsequently improved after systemic antifungal therapy. Presumably, itraconazole by inhibiting CYP3A4 enzyme caused an increase in plasma methylprednisolone levels. This probably led to a profound immunosuppressed state, which predisposed to the development of IPA. We performed a systematic review and identified nine cases of IPA following ABPA. The disease course is fulminant, and only three of the nine patients survived. Physicians treating ABPA patients should be aware of this potentially fatal overlap. Clinical suspicion and early diagnosis are crucial to improve the patient outcomes.
