PCR monitoring of response to liposomal amphotericin B treatment of systemic candidiasis in neutropenic mice.

چکیده
When a diagnosis of invasive candidiasis has been made, treatment with toxic fungicidal agents is inevitable. The crucial decision of when to stop such treatment is difficult to make, because cultures are often negative despite ongoing invasive candidiasis and can therefore not be used as a reliable parameter of effective therapy. In the present study, the use of PCR in monitoring the therapeutic efficacy of antifungal treatment with liposomal amphotericin B was evaluated by using neutropenic mice with systemic candidiasis. Blood cultures of infected mice treated with different doses of liposomal amphotericin B were only positive at the early onset of the infection process and became sterile within 3 days; this was true even with mice treated with 1 mg of liposomal amphotericin B per kg of body weight that experienced a relapse of infection 14 days later. A significant correlation between presence of Candida albicans in the kidneys and PCR results obtained with blood was demonstrated. Thus, PCR results obtained with blood samples correlated well with the therapeutic efficacy of antifungal treatment.

Micafungin versus liposomal amphotericin B for pediatric patients with invasive candidiasis: substudy of a randomized double-blind trial.
BACKGROUND Invasive candidiasis is increasingly prevalent in premature infants and seriously ill children, and pediatric data on available antifungal therapies are lacking. METHODS We conducted a pediatric substudy as part of a double-blind, randomized, multinational trial to compare micafungin (2 mg/kg) with liposomal amphotericin B (3 mg/kg) as first-line treatment of invasive candidiasis. ...
متن کاملEfficacy of liposome-intercalated amphotericin B in the treatment of systemic candidiasis in mice.
We developed a liposome-intercalated preparation of amphotericin B by using small, unilamellar vesicles 0.06 to 0.1 micron in diameter. In contrast to previously described liposomal preparations of amphotericin B, these vesicles have the advantage that they are small enough to be filter sterilized. We compared the efficacy of liposomal amphotericin B with that of the commercial drug given as an...
متن کاملNew developments in the diagnosis and management of invasive fungal infections.
Invasive fungal infections in cancer patients are on the increase. Candidemia is now the fourth leading cause of bloodstream infections in many intensive care units (ICUs). Although a number of risk factors have been identified, antifungal therapy should not be started in non-neutropenic patients until a diagnosis of invasive candidiasis or candidemia is made or presumed in order to avoid the d...
متن کاملAnidulafungin pharmacokinetics and microbial response in neutropenic mice with disseminated candidiasis.
Candidemia is often fatal, especially in patients with persistent neutropenia. New therapies are needed. We performed 24-h pharmacodynamic studies to compare the efficacies of anidulafungin, fluconazole, and amphotericin B in neutropenic mice with disseminated candidiasis caused by one of three strains of Candida glabrata. Anidulafungin produced a maximal fungal kill (E(max)) of 1.4 to 1.9 log(...

Background: Systemic candidiasis is a major complication in neutropenic cancer patients undergoing treatment. Most systemic fungal infections emerge from endogenous microflora so the aim of the present study was to identify Candida species isolated from the different regions of body in neutropenic patients in compare with the control group. Methods: A total of 309 neutropenic can...
