A highly sensitive, selective, and precise ultra-performance liquid chromatography tandem mass spectrometry method was developed and validated for simultaneous quantification of itraconazole and hydroxy itraconazole in human plasma by a single liquid-liquid extraction step. The precursor to product ion transitions of m/z 705.3/392.3, m/z 721.2/408.3 and m/z 708.2/435.4 were used to detect and q...
BACKGROUND Itraconazole has been proved therapeutically effective against a variety of human cancers. This study assessed the effect of itraconazole on the Hedgehog (Hh) pathway and proliferation of human gastric cancer cells. METHODS CCK-8 assay and colony formation assay were used to assess the effects of itraconazole on proliferation of gastric cancer cells. The expression of Hh signaling ...
AIMS To compare the serum concentrations of itraconazole and hydroxyitraconazole after treatment with itraconazole cyclodextrin solution and itraconazole capsules in human immunodeficiency virus (HIV) positive patients with oral candidosis. METHODS The pharmacokinetics of itraconazole and its active metabolite hydroxy-itraconazole were assessed on days 1 and 7 of therapy in acquired immunodef...
OBJECTIVE The therapeutic activities of cyclodextrin-associated itraconazole oral solution (itraconazole OS) by two administration routes in experimental oral and oesophageal candidiasis in mice were examined and compared. METHODS Using experimental oral and oesophageal candidiasis models in ICR mice, we investigated the efficacy of oral and intragastric administration of itraconazole OS and ...
phaeohyphomycosis is an amalgam of clinical diseases caused by a wide variety of dematiaceous fungi. we are reporting on a 16 year-old patient from amol with subcutaneous cervical nodes and nasopharyngeal lesions of phaeohypho mycosis that were confirmed by pathological examination, direct smear, and culture. after treatment with an oral triazole (itraconazole) for 4 months, all nodes and lesio...
OBJECTIVE To study the main molecular mechanisms responsible for itraconazole resistance in clinical isolates of Candida krusei. METHODS The 14α-demethylases encoded by ERG11 gene in the 16 C.krusei clinical isolates were amplified by polymerase chain reaction (PCR), and their nucleotide sequences were determined to detect point mutations. Meanwhile, ERG11 and efflux transporters (ABC1 and AB...
OBJECTIVES To examine whether in vitro antifungal susceptibility test results correlate with in vivo efficacy of two cyclodextrin-solubilized itraconazole formulations (intravenous and oral) against Candida in a murine model of invasive infection. METHODS A selected set of 12 Candida spp. strains with various itraconazole susceptibilities were tested. We studied the efficacy of intravenous an...
Microbroth dilution tests in vitro showed the same IC(50) values for itraconazole and hydroxy-itraconazole, within a mode +/- one dilution range of experimental error, for 90% of 1481 isolates of pathogenic fungi, representing 48 genera. Some 10-15% of Candida glabrata and Trichophyton mentagrophytes isolates were more susceptible to itraconazole than hydroxy-itraconazole. Replicate tests with ...
This is the first report of a detailed relationship between triazole treatment history and triazole MICs for 154 Aspergillus fumigatus clinical isolates. The duration of itraconazole dosage increased as the itraconazole MIC increased, and a positive correlation was observed (r = 0.5700, P < 0.0001). The number of itraconazole-naïve isolates dramatically decreased as the itraconazole MIC increas...
Prophylactic fluconazole prevents candidiasis; however, this drug has no activity against molds. We performed a randomized trial to determine whether prophylactic itraconazole prevents invasive mold infections (IMIs). A total of 304 patients receiving allogeneic stem cell transplants (SCT) were randomized to receive fluconazole (400 mg/d) or itraconazole (oral solution 2.5 mg/kg 3 times daily, ...
