Objective: To investigate the efficacy and safety of liposomal amphotericin B (L-AmB) for the salvage treatment of invasive fungal disease (IFD) in patients with hematological diseases. Methods: Data were retrospectively collected from 80 patients with hematological issues treated with L-AmB between June 2023 and December 2023 after failure of previous antifungal therapy. Baseline patient information, clinical efficacy, and factors affecting the efficacy of L-AmB were analyzed by logistic regression. Moreover, adverse effects associated with L-AmB were evaluated. Results: Among the 80 patients, 9 (11.2%) had proven IFD, 43 (53.8%) had probable IFD, and 28 (35.0%) had possible IFD. The efficacy rate of L-AmB salvage therapy for IFD was 77.5%, with a median daily dose of 3 (range: 1-5) mg·kg(-1)·d(-1) and a median dosing course of 14 (range: 8-25) days. Multivariate logistic regression analysis showed that the disease remission status ( OR =4.337, 95% CI 1.167-16.122, P =0.029) and duration of medication ( OR =1.127, 95% CI 1.029-1.234, P =0.010) were independent factors affecting the efficacy of L-AmB. The incidence of infusion reactions associated with L-AmB, including fever and chills, was 5.0%. The incidence of hypokalemia was 28.8% (predominantly grades 1-2), and the incidence of nephrotoxicity was 11.3% (predominantly grades 1-2) . Conclusion: L-AmB is safe and effective in the treatment of patients with IFD who are intolerant to or who have experienced no effect of previous antifungal therapy, with a low rate of adverse reactions.
