There are limitations on diagnostic methods to differentiate between active and latent tuberculosis (TB), and the prediction of latent progression to TB disease is yet complex. Traditionally, tuberculosis-specific host immune response was visualized using the tuberculin skin test. Nowadays, IFN-γ re
Eumycetoma caused by Madurella mycetomatis is treated surgically and with high doses of ketoconazole. Therapeutic responses are poor, and recurrent infections are common. In search of therapeutic alternatives in the treatment of mycetoma, we determined the in vitro susceptibilities of M. mycetomatis
A high-dose-step-down strategy for caspofungin treatment was evaluated in an experimental model of advanced-stage invasive pulmonary aspergillosis. The therapeutic efficacy of caspofungin in relation to the severity of invasive pulmonary infection caused by Aspergillus fumigatus in transiently neutr
Objectives: Improvement of the efficacy of drug treatment in mycobacterial infection by the development and application of targeted drug delivery. Methods: In disseminated Mycobacterium avium infection in mice, the relative efficacy of the antimycobacterial agents that are currently used in combinat
Objectives: The effect of ceftazidime dosing increments and frequency of dosing on the selection of ceftazidime-resistant Enterobacter cloacae in the intestine was studied in rats, during treatment of a pulmonary infection caused by Klebsiella pneumoniae. Methods: Rats with pulmonary infection (n 5
In common with a proportion of patients with invasive pulmonary aspergillosis (IPA), the efficacy of AmBisome treatment regimens in our rat model remains suboptimal. To investigate whether this might be the result of initially low antifungal activity of amphotericin B at the site
In a previous study in experimental Klebsiella pneumoniae pneumonia, the therapeutic potential of ciprofloxacin was significantly improved by encapsulation in polyethylene glycol-coated ("pegylated") long-circulating (STEALTH) liposomes. Pegylated liposomal ciprofloxacin in high do
Animal and clinical data show that high ratios of the area under the concentration-time curve and the peak concentration in blood to the MIC of fluoroquinolones for a given pathogen are associated with a favorable outcome. The present study investigated whether improvem
Antimicrobial agents may interact synergistically. But to ensure synergy in vivo, the drugs should both be present at the site of infection at sufficiently high concentrations for an adequate period of time. Coencapsulation of the drugs in a drug carrier may ensure para
Liposome-encapsulated amikacin has recently entered clinical trials. The rationale for liposome encapsulation of aminoglycosides is the possibility to increase the therapeutic index of this class of antibiotics by increasing aminoglycoside concentrations at the site of infection an
