Filter by:Invasive Candida infections are serious complications in immunocompromised patients including those undergoing treatment for cancer but occur also in patients treated in ICUs. Survival rate of invasive candidiasis is associated with early initiation of antifungal therapy (15% mortality rate for candidemic patients with antifungal therapy on day 0 related to the culture date of the first blood sample positive for yeasts compared to 41% for patients who received antifungal therapy on day 3). Up to date, no laboratory method or clinical decision rule is available for correct anticipation of invasive candidiasis which would avoid delays in appropriate antifungal therapy initiation. In clinical practice culture based methods (e.g. blood cultures) miss up to 50% of invasive candidiasis cases. Preemptive antifungal therapy is therefore often initiated in critically ill patients after Candida has been isolated from various non-sterile patient samples even without any sufficient evidence for invasive candidiasis. The disadvantages of this approach include over- and undertreatment of patients (up to 50% of candidemia cases are missed, and on the other hand 89% patients are treated unnecessarily), increased selective pressure for the development of antifungal resistance, potential risk of adverse drug reactions, and increased costs (expenses for antifungal therapy account for half of the antimicrobial medication budget in tertiary care hospitals). In addition, no survival benefit could be demonstrated by this strategy in ICU patients. The aim of this study is to identify biological markers to anticipate or support the diagnosis of invasive candidiasis in ICU patients, to overcome current deficiencies in detection of invasive candidiasis and consequently to differentiate between Candida spp. colonization and invasive Candida infection. The investigators intend to examine time dependent courses of potential host and pathogen derived biomarkers as well as innate or acquired predispositions for invasive candidiasis; e.g. automated (1→3) ß- D- Glucan tests, DNA in serum blood samples, pathogen recognition receptors and serum markers like interleukin (IL)-1, IL-2, IL-6, IL-10, IL-12, IL-17A, IL-17F, IL-22, IL-23, Tryptophan, Kynurenine, composition of indigenous microbiota of gastrointestinal and lower respiratory tract and skin, and risk factors for invasive candidiasis like underlying diseases and treatments. The study should contribute to improved assessment of ICU patients at risk for invasive candidiasis and to improved diagnosis of invasive candidiasis in ICU patients. In clinical practice the reliable differentiation between infection and colonization will allow more targeted antifungal therapy leading to enhanced antifungal treatment initiation on the one hand (in cases of true invasive candidiasis) and to reduction of unnecessary antifungal treatments and treatment costs on the other hand.
The purpose of this study is to determine if intravenous CD101 is safe and effective in the treatment of candidemia and/or invasive candidiasis when compared to caspofungin (followed by oral fluconazole).
Fluconazole is the first-line agent in the treatment of invasive candidiasis. Studies showed inappropriate drug exposure causes high mortality in critically ill patients. Under-dosing and ineffective fluconazole trough serum concentrations were found in a recent retrospective study. Variability in fluconazole exposure can be easily measured with therapeutic drug monitoring. For patient groups who are at risk for drug underexposure, therapeutic drug monitoring can be valuable regards decreasing mortality.
The purpose of the study is to 1) define the operating characteristics of fungal biomarker assays in pediatric patients at high-risk for developing invasive candidiasis, 2) determine the change in fungal biomarker assay results in children who develop invasive candidiasis, and 3) create a biobank of blood samples from pediatric patients at high-risk for invasive candidiasis and those with invasive candidiasis for future testing of fungal biomarker assays and development of new fungal biomarker assays. The study will assemble a prospective cohort of pediatric patients at high-risk for developing invasive candidiasis. Blood samples for biomarker testing will be obtained at the time a patient has a clinical indication for blood culture attainment. Additional blood sampling will be performed on the sub-set of patients that are found to have invasive candidiasis. The sensitivity, specificity, PPV, and NPV of biomarker assays will be determined for each biomarker assay. No PHI will be stored in the database and limits on blood draws (3 ml/kg in an 8 week period) will be adhered to.
Invasive fungal infections (IFIs) are a frequent cause of morbidity and mortality in high-risk patients, such as immunocompromised patients. Candida is currently the predominant fungal pathogen in these patient populations and is associated with significant morbidity and a high mortality. Micafungin (MCF) is a semisynthetic compound belonging to the new class of antifungal agents, the echinocandin lipopeptides, that has potent in vitro and experimental in vivo activity against a variety of pathogenic Candida species and Aspergillus species. Its applied indications are so the treatment and/or the prophylaxis of Candida and Aspergillus infections. MCF is currently licensed for the treatment of candidiasis at doses of either 100 or 150 mg a day. The efficacy of MCF is linked to the area under the concentration-time curve over 24 h in the steady state divided by the MIC (AUC0-24/ MIC ratio). On one hand: - It was demonstrated that 98% of invasive candidiasis patients with a MCF AUC/MIC ratio between 3 and 12 achieve microbiological clearance, as opposed to only 85% of those with an AUC/MIC ratio < 3. In the case of infections by Candida parapsilosis, which exhibits drug MICs that are 50- to100-fold higher, 100% of patients with an AUC/MIC ratio >285 achieve microbiological clearance, as opposed to 82% of those below that exposure level.(1) On the other hand: - It is well known that patients of intensive care units (ICU) are characterized by particular pharmacokinetic parameters with higher apparent volume of distribution (VC/F) and/or higher apparent systemic clearance (CL/F). In a population of healthy volunteers, it was observed that CL/F of MCF presents a high interpatient variability.(2) - Whether most ICUs patients achieve optimal AUC/MIC ratio thresholds at standard doses has not been investigated so far. In particular, lower AUCs might be reached in patients having the highest VC/F values. Such patients would then be at risk of therapy failure and would benefit from individualized-dosing strategies. In this context, the study of the pharmacokinetics of MCF in critically ill patients seems to be necessary.
Invasive Candida infections are burdened with a high mortality rate and is very common in intensive care units. This study aims to evaluate the efficacy of empirical treatment with micafungin in adult patients with suspected invasive candidiasis.
A study of micafungin in ICU versus non-ICU patients showed a significantly lower treatment success in ICU patients compared with non-ICU patients. It is known that in critically ill patients, alterations in function of various organs and body systems can influence the pharmacokinetics and hence the plasma concentration of a drug. The pharmacokinetic parameters of micafungin in critically ill patients are most likely different, but this has not been specifically studied. The pharmacokinetic parameters of micafungin in critically ill patients will be established and plasma concentrations of micafungin will be correlated with disease severity.
