Pharmacokinetics of Micafungin in Critically Ill Patients
Critical IllnessInvasive CandidiasisA 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.
NOBICS - NOvel BIomarker In Invasive CandidiasiS/Candida Sepsis
Invasive CandidiasisInvasive 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.
Changing Patterns of Candida Infections in Urban Medical Centers
InfectionCandida1 moreThe purpose of this study is to determine the changing patterns of infection caused by Candida species in urban medical centers and its influence on patient outcomes. A retrospective cohort study design will be employed with the main outcome measure being hospital mortality. Secondary outcomes including microbiologic clearance of the infection, duration of hospitalization, and the intensive care unit (ICU) length of stay will also be assessed.
Point-of-care Tests for Bacterial Vaginosis and Candidosis
InfectionBacterial3 moreVaginal infection in early pregnancy is associated with an increased risk of spontaneous preterm delivery and late miscarriage. Most studies presume that vaginal infections are responsible for up to 40% of preterm birth. Although the causative microorganisms of vaginal infections are manifold, the three pathogens most commonly associated with vaginal infections are Gardnerella vaginalis, Candida albicans and Trichomonas vaginalis. The aim of this prospective study is the validation of the point-of-care tests OSOM BVBLUE for bacterial vaginosis and SavvyCheck Vaginal Yeast Test for candidosis in comparison to Gram stain.

Invasive Candidiasis; Treatment With EchinocandinThe study consists in taking 4 tubes of blood at different times over a period of 10 days, via a catheter (central venous or arterial catheter) already in place in the usual therapeutic management. These samples will make it possible to measure blood levels of certain markers specific to invasive candidiasis. PCR will be used to quantify fungal load precisely, that is to say the quantity of yeast present in the blood and to monitor this quantity over time. These samples will be transferred to a specialized unit and stored for a maximum of three years for use at the end of the study.
Antigenic and Antibody Detection of Candida
To Evaluate the Diagnostic Value of Candida Antigen Antibody Detection for Candida InfectionIn this study, a multicenter, prospective, synchronous blind, and controlled study was adopted to set the cut-off values of candida specific IgG, IgM, and Mn with the blood culture results as the gold standard, so as to evaluate the diagnostic value of candida specific IgG, IgM, and Mn levels in candida infection. the cut-off values of serum specific IgG, IgM and Mn of candida sinensis infected population in China were established by comparing the positive results of blood culture of 300 healthy people and 100 patients with positive candida sinensis blood culture as the gold standard and using ROC curve (ROC curve). 100 patients with positive tracheal aspiration culture and 100 patients with positive urine culture were enrolled. Serum levels of candida specific IgG, IgM and Mn were detected, and sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratio of candida specific IgG, IgM and Mn in tracheal aspiration and urine were evaluated. 200 high risk patients with candida infection were enrolled, and the aseptic fluid culture and the simultaneous detection of serum specific IgG, IgM and Mn were adopted to explore the diagnostic value of the detection method. positive candida culture in sputum and positive candida culture in tracheal aspirate were taken as the control group to compare the levels of IgG, IgM and Mn in serum of the two groups, and to explore the diagnostic value of different sampling methods for candida pulmonary infection.
