Prophylaxis for aspergillosis in patients with haematological malignancies: pros and cons.

INTRODUCTION: Along with new diagnostic options, comes the recent development of novel antifungal agents that expanded the spectrum of activity over traditional treatments contributing to the successful management of fungal diseases. Nevertheless, invasive fungal infections (IFI) represent a major hindrance to the favorable outcome of patients with hematologic malignancies. According to these observations, an appropriate prevention of IFI occurring in hematologic patients should be considered of paramount importance. However, the wide use of antifungal agents may facilitate the emergence of resistance and may be associated to the occurrence of severe adverse events and eventually may significantly increase the cost of therapeutic procedures. Areas covered: The aim of present review is to analyze advantages and disadvantages of primary antifungal prophylaxis (PAP) in hematologic patients. Expert commentary: Patients with AML/MDS undergoing intensive chemotherapy and patients receiving stem cell transplantation are at high risk of IFI, and therefore may benefit form PAP, although several additional factors should be carefully evaluated in our decision-making approach, including the local epidemiology and the prompt availability of diagnostic facilities. The advent of new treatment options for hematologic patients such as target therapies might facilitate the rise of new risk categories so far underestimated.
