Treatment of invasive fungal infections in high-risk haematological patients: what have we learnt in the past 10 years?

Invasive fungal infection (IFI) caused by filamentous fungi remains a very severe infectious complication in patients with onco-haematological diseases. Last advances in the diagnostic and therapeutic fields, today we know that their contributions are limited. Something similar can be said of clinical trials especially in relation to some changes in the characteristics of the host. The development of promising diagnostic techniques and the relative expansion in the number of antifungal agents has been associated with diversification of therapeutic strategies (prophylaxis with extended-spectrum azoles and preemptive antifungal treatment). However, the low sensitivity of AGA testing in some circumstances, and the potential delay in starting treatment due to logistic reasons, has been reflected by a greater mortality in certain type of patients and a significant increase in the days of treatment. All these circumstances has once again focus attention to the empirical approach as a central strategy in high-risk patients. The objective of this article is to review the clinical experience in the treatment of IFI in onco-haematological patients according to data published in the literature in the last decade and to present a set of recommendations.
