Background: Although the level of medical care has been improved in recent years, the probability of patients contracting pathogens has increased greatly, with a rising incidence of invasive fungal infections. Deep-seated fungi have become common pathogens of nosocomial infections.
Objective: This study aims to systematically assess the effectiveness, mortality, survival rate, and adverse reactions (ARs) of high-dose (HD) liposomal amphotericin B (L-AMB) for human diseases.
Methods: Ten articles (1661 patients) of randomized controlled trials (RCTs; whether randomized, single-blind, or double-blind) from January 1, 1960, to December 31, 2020, of HD-L-AMB treatment of diseases were retrieved from the PubMed, Embase, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials databases. The primary outcome measure was the overall therapeutic effect, and the secondary outcome measures were mortality, ≥10-week survival, and ARs. Data were meta-analyzed using RevMan 5.3.
Results: Ten RCTs involving 1661 patients were included. HD-L-AMB did not show a significant therapeutic advantage in anti-infection treatment. In addition, HD-L-AMB treatment of invasive Aspergillus infection led to high mortality and low survival (≥10 weeks, OR = 0.57, 95%CI 0.34-0.94, P = .03). According to subgroup analysis, the incidence of ARs and the incidence of renal dysfunction associated with invasive fungal infection treatment were higher with HD-L-AMB than with regular-dose L-AMB.
Conclusion: HD-L-AMB had no obvious advantage for the treatment of diseases and was accompanied by increased mortality, reduced long-term survival, and increased ARs (including renal insufficiency). Therefore, the use of HD-L-AMB to control infections is recommended with caution only when the preferred treatment is contraindicated.
