Active clinical trials for "Invasive Fungal Infections"

In this trial, our goal is to determine the pharmacokinetics of micafungin in a non-selected cohort of patients with suspected or proven invasive fungal infections. Patients will receive micafungin for the period necessary to achieve clinical and / or mycological cure. An attempt will be made to have 2 PK curves, one full and one limited sampling on days 3 (n=9) and 7 (n=5). Furthermore, we will be able to determine intra-individual variability. On non-PK days, trough samples will be taken to determine the time to steady state. All samples will be taken just prior to the morning dose of micafungin. All infusion rates will be according to the SPC label information. Patients are considered to be evaluable if at least the first PK curve has been completed. Two moments of PK analysis will enable us to determine whether there is an increase over time in exposure if steady state has not been reached.

The pharmacokinetics of fluconazole are expected to be different in ICU patients compared to non-ICU patients. The investigators will determine fluconazole and free fluconazole concentrations in 20 ICU patients, who will get intravenous fluconazole as standard care. Switching to oral/enteral fluconazol is allowed after day 3. A full pharmacokinetic curve will be taken on day 3 of iv therapy and limited pharmacokinetic curves on day 7 of iv therapy and/or on day 3 of oral therapy; trough levels will be taken daily after intravenous therapy.

In the context of screening for infectious fungal diseases in patients with malignant haemopathy, and particularly patients with acute leukaemia, the investigator aims to evaluate the performance of an already commercialized but little used serum screening test (Fungitell® test) and to determine its place in the management strategy for invasive aspergillosis.

Voriconazole is an effective antifungal agent and may decrease morbidity and mortality for patients with invasive fungal infections. It is metabolized via liver enzymes. However, these enzymes exhibit different activities in individual patient (genetic polymorphism). Higher proportions of Asians metabolize voriconazole slower than Caucasians and African Americans do. Slower metabolizers may experience dose-associated adverse events more frequently, such as visual disturbances, liver function test abnormalities, and neurological complications. On the other hand, extensive metabolizer or other physiologic conditions may lead to lower blood levels of voriconazole, which may result in treatment failure. We plan to enroll patient who take voriconazole and examine their liver enzyme activities and blood samples for peak and trough drug levels. We will collect potential factors affecting voriconazole levels, and correlate the levels with the dosing regimen, activity of liver enzyme, occurrence of adverse events, and treatment outcomes. The goal of this study is to determine if monitoring of voriconazole blood levels is necessary in Taiwan.

This was a prospective clinical study that all voriconazole-treated adult Chinese patients with invasive pulmonary infection admitted to Zhengzhou Central Hospital affiliated to Zhengzhou University from March 2018 to April 2020.

This study is to evaluate safety and prophylaxis effect of micafungin after hematopoietic stem cell transplantation. Micafungin is administered until confirmation of neutrophil engraftment or treatment failure.

The pharmacokinetics of caspofungin are expected to be different in ICU patients compared to non-ICU patients. The investigators will determine caspofungin concentrations in 20 ICU patients, who will get caspofungin as standard care. Full PK curves will be taken on day 3 and a limited PK curve on day 7, trough levels will be taken daily.

The purpose of this program is to determine the frequency of the use of Posaconazole in immunocompromised patients refractory to first line therapy receiving therapeutic treatment based on different pathogens in comparison to other antifungal therapy. A further objective is to determine the frequency of the use of Posaconazole in immunocompromised patients receiving prophylactic treatment in comparison to other antifungal prophylaxis.

Caspofungin (CAS) is used to prevent and treat invasive fungal infections patients older than 3 months. However, the optimal dosing strategy of CAS is lacking in adolescents from 12 to 17 years old, especially those undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT), who are vulnertable to fungal infections. The study aimed to establish a population pharmacokinetic (PPK) model and assess the dosing schemes of CAS in adolescents with allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Invasive fungal disease in the critically ill patient is a serious complication that increases hospitalization times, morbidity and mortality, and healthcare costs. Our team proposes a retrospective observational study of patients from the resuscitation unit of the Hospital la Fe who during the years 2016-2019 presented invasive candidiasis. The investigators intend to detect if there are possible specific risk factors that favor the development of invasive candidiasis in colonized patients and if these associated risk factors could be considered as 'triggers' or alerts for the implementation of specific care in these patients. To do this, the investigators intend to study the blood samples taken from patients, taking into account different types of perioperative variables from them, which will be statistically analyzed, so that evidence-based inferences can be drawn to demonstrate our hypothesis.
