Posaconazole for primary antifungal prophylaxis in patients with acute myeloid leukaemia or myelodysplastic syndrome during remission induction chemotherapy: a single-centre retrospective study in Korea and clinical considerations.

Abstract

Posaconazole was introduced as the primary antifungal prophylaxis (PAP) in acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS) patients during remission induction chemotherapy. Data on breakthrough invasive fungal infections (IFIs) from various centres are essential, as there are several considerations in treating IFIs in the posaconazole era. The aim of this study was to evaluate the effectiveness of posaconazole PAP and identify characteristics of IFIs at a single centre in Korea. We retrospectively reviewed consecutive patients with AML/MDS undergoing remission induction chemotherapy between December 2010 and November 2013. Of the 424 patients, 140 received posaconazole and 284 received fluconazole prophylaxis. The incidence of breakthrough proven/probable IFIs (15.5% vs. 2.9%, P < 0.001) and empirical antifungal treatment (EAFT) (45.8% vs. 12.9%, P < 0.001) decreased in the posaconazole group compared to the fluconazole group. In the posaconazole PAP group, two cases of breakthrough mucormycosis were noted among 13 proven/probable/possible IFI cases (15.4%). Overall and IFI-related mortality was 12.1% and 1.9% respectively. Fungus-free survival was significantly higher in the posaconazole group (74.7% vs. 87.1%, P = 0.028). Breakthrough IFIs and EAFT decreased significantly after posaconazole PAP. The benefit in fungus-free survival was noted with posaconazole PAP. Clinicians should be vigilant to identify non-Aspergillus IFIs with active diagnostic effort.
