Killing Rates of Caspofungin in 50 Percent Serum Correlate with Caspofungin Efficacy Against Candida albicans in a Neutropenic Murine Model

Efficacy of single large doses of caspofungin in a neutropenic murine model against the "psilosis" group.

We compared the in vivo efficacy of single large dose of caspofungin to that of daily smaller caspofungin doses (with same cumulative doses) against C. albicans (echinocandin susceptible and resistant isolates) and the “psilosis� group in a neutropenic murine model. Seven treatment groups were formed for C. orthopsilosis, C. metapsilosis and C. albicans (no treatment, 1, 2 and 3 mg/kg caspo...

Efficacy of caspofungin against invasive Candida or invasive Aspergillus infections in neutropenic patients.

BACKGROUND Neutropenia is an indicator of poor prognosis in patients with fungal infections. All available clinical trial experience from the caspofungin development program was reviewed to ascertain the efficacy of caspofungin in neutropenic patients with documented invasive aspergillosis (IA) or invasive candidiasis (IC). METHODS The review was limited to neutropenic patients with proven IC...

Effect of Fluconazole, Amphotericin B and Caspofungin against Candida albicans

Efficacy of caspofungin combined with amphotericin B against azole-resistant Candida albicans.

The activity of caspofungin (CFG) combined with amphotericin B (AMB) against azole-resistant Candida albicans was evaluated in vitro (chequerboard) and in vivo (murine). CFG+AMB resulted in positive interactive effects in vitro (fractional inhibitory concentration index 0.75). Compared with untreated controls, CFG+AMB prolonged mouse survival (P = 0.006) and compared with AMB alone, CFG+AMB pro...

Comparison of killing activity of caspofungin against Candida parapsilosis, Candida orthopsilosis and Candida metapsilosis.

methods. In the other instance, a BLPAR strain was designated ampicillin-susceptible by Etest (MIC 1⁄4 1 mg/L), ampicillinintermediate by M.I.C.E. (MIC 1⁄4 2 mg/L) and ampicillin-resistant by BMD (MIC 1⁄4 16 mg/L). As stated earlier, the low MICs when gradient methods were used were because of a faint growth within the inhibition zone that was difficult to detect at 24 h. In contrast to the fin...
