Since the broad implementation of ibrutinib therapy, an increasing number of studies have been reported on invasive fungal infections (IFI) associated with ibrutinib administration. We conducted a retrospective cohort study in three hospitals in south-east Austria in order to assess the local epidemiology of ibrutinib associated IFIs. A total of 113 patients with underlying hematological malignancy were included in the study. During the study period, a single IFI episode was observed, which corresponds to an IFI incidence of 2.3 cases per 100 person years (95% CI: 0.12-11.47). IFIs during ibrutinib therapy seem to be a rare event in case of absent additional risk factors for IFIs.
Keywords: hematologic malignancy, invasive fungal infection; small molecule kinase inhibitor, ibrutinib.
Ibrutinib is an effective drug used to treat a variety of blood cancers, but it might increase risk for life-threatening invasive fungal infections (IFIs). In our study, a low number (1 IFI per 43 patient years) of patients on ibrutinib developed an IFI.
