Candida albicans biofilms complicate the treatment of infected implanted intravascular devices because of decreased antifungal susceptibility. In our investigation, 48 rabbits with experimental central venous catheter C. albicans infection were equally allocated to a control arm or to receive amphotericin B deoxycholate or caspofungin treatment while undergoing systemic and intraluminal lock therapy for 7 days. C. albicans was cultured from catheters from all control rabbits, from 3 that received amphotericin B, and from 0 that received caspofungin. Differences in colony counts were detected between the control and amphotericin (P<.001) and control and caspofungin (P<.001) arms. Caspofungin may be useful in the treatment of C. albicans biofilm-associated intravascular catheter infections, which warrants further study.

Based on DMR022 [(AEEA-Gly)-AEEA-amphotericin B methyl ester, AEEA is the abbreviation of 8-amino-3,6-dioxaoctanoic acid] and DMR031 [(AEEA)-amphotericin B methyl ester], DMR040 [(AEEA)-amphotericin B methyl ester] was further designed and synthesised. Firstly, DMR040 was assessed for its antifungal activity and haemolytic toxicity with the broth dilution method and sterile defibrinated sheep blood, respectively. The minimal inhibitory concentration (MIC) of DMR040 (2 μg/mL) against Candida albicans ATCC 10231 and ATCC 90028 was reduced by 2 times compared to that of amphotericin B (1 μg/mL).

Amphotericin B (AmB) has been a cornerstone in the treatment of invasive fungal infections for over 6 decades. Compared with conventional amphotericin B deoxycholate (AmB-DOC), liposomal amphotericin B has comparable efficacy but less nephrotoxicity. The main purpose of this study was to investigate the reason why liposomal amphotericin B has similar therapeutic effects but lower toxicity and the differences of distribution in humans between liposomal amphotericin B and AmB-DOC.

Background: Amphotericin B deoxycholate (AmB-D) have potential toxic effects in the treatment of talaromycosis, and high-quality, non-generic liposomal AmB (L-AMB) is still inaccessible in many regions of China. As such, the efficacy and safety of alternative drugs warrant further investigation for the management of talaromycosis. This study aimed to compare the efficacy and safety of Amphotericin B Colloidal Dispersion (ABCD) and AmB-D for the treatment of talaromycosis in a retrospective cohort of HIV-infected patients.

Background: Voriconazole, isavuconazole, and amphotericin (AmB) formulations are currently recommended to treat invasive pulmonary aspergillosis (IPA). We aimed to estimate the efficacy of different antifungal drugs in the initial treatment of IPA.
Methods: We included all available randomized controlled trials (RCTs) evaluating first-line treatments for IPA by searching PubMed, Medline, EMBASE, the Cochrane Library, and the ClinicalTrials.
