ABSTRACT
Invasive pulmonary aspergillosis (IPA) usually occurs in severely immunocompromised patients. The expanded use of glucocorticoids (GC) in clinical practice accounts for the increasing number of fungal infections reported in mildly or non-immunocompromised hosts. We report a series of 8 patients with fungal pneumonia in whom long term high dose GC treatment was the only risk factor for opportunistic infections. All patients except one had chronic underlying disorders (asthma, idiopathic fibrosis, chronic obstructive pulmonary disease, COPD). Seven patients were diagnosed with pulmonary aspergillosis. Etiological suspicion of fungal infection was obtained during lifetime in six cases and in one case was confirmed only in the post-mortem examination. In most cases bronchoscopic techniques allowed identification of the microorganism. However, delay in establishing the diagnosis (mean 20 days) precluded a prompt initiation of a specific treatment. The course of the fungal infection was ominous. All but one patient experienced progressive respiratory failure requiring ICU admission and mechanical ventilation support. Despite this, all of them died. The only survivor was a patient receiving early empirical antifungal treatment due to a high clinical suspicion of fungal infection. Based on the present and previous findings, antifungal treatment should be considered in chronic respiratory patients requiring high or repetitive doses of GC when there is clinical evidence of pneumonia and isolation of Aspergillus spp. from respiratory secretions.
