Objective: To evaluate the efficacy of primary prophylaxis of voriconazole against invasive infection of pulmonary aspergillosis (IPA) during remission-induction chemotherapy (RIC) of patients with acute myeloid leukemia (AML).
Methods: Clinical data of 102 de novo AML patients who received primary anti-IPA prophylaxis during the first induction chemotherapy were analyzed retrospectively. All the cases were divided into voriconazole-treated group and posaconazole-treated group according to the prophylactic agent. The incidences of IPA and systemic antifungal treatment during induction chemotherapy were analyzed for both groups.
Results: Among 102 enrolled cases, 42 cases received voriconazole and other 60 received posaconazole as primary prophylaxis. IPA occurred in 3 cases of voriconazole group (1 probable, 2 possible); IPA occurred in 4 cases of posaconazose group, and all were possible cases. The incidence of IPA during remission-induction chemotherapy in variconazole group equaled to posaconazose group (7.1% vs. 6.7%) (P=0.925). Beside IPA cases, 2 cases in voriconazole group and 4 cases in posaconazole group received intravenous anti aspergillosis drugs preemptive treatment, and no significant difference of prophylactic success rate was observed between two groups (88.1% vs. 86.7%) (P=0.831). Visual disturbance was the most common adverse event occurred in voriconazole group, but no significant differences of incidences of other adverse effects were observed when compared with posaconazole group.
Conclusion: According to similar prophylactic effect with posaconazole, voriconazole appears to be a good alternative for primary prophylaxis of IPA during remission-induction chemotherapy in AML patients.
