Filter by:Fungal infections in immunocompromised patients occuring during construction activities in hospitals have repeatedly been reported. However, the question of a causal relation between construction activities and infections has never been addressed systematically and prospectively. To answer this question, we will monitor our immunosuppressed patients' health status, as well as fine dust and aspergillus spore contents in the air during a three year construction activity period in our hospital.
The purpose of this study is to compare the efficacy and safety of isavuconazole versus voriconazole in the treatment of patients with invasive aspergillosis.
This study investigates the safety and tolerability as well as the efficacy and pharmacokinetics of caspofungin in four escalating dosages in adult patients with hematologic malignancies and proven or probable invasive aspergillosis.
The trial is planned as a multicentric, national, phase II, open-label trial to evaluate safety and tolerance of nebulized Liposomal Amphotericin B (Ambisome) for LMA patients during the induction therapy ,intensification, plus Allogeneic Haematopoietic Progenitor Cell transplant in due course, as well for patients diagnosed of several malignant haematologic diseases and treated with Allogeneic Haematopoietic Progenitor Cell Transplant
We wanted to determine the efficacy and the safety of caspofungin acetate (CANCIDAS®) in the treatment of invader fungal infection (IFI) specifically, Invasive Candidiasis (CI) in adults patients without neutropenia and Invasive Aspergillosis (AI) in adults patients who are refractory to or intolerant of other therapies (i.e., amphotericin B, lipid formulations of amphotericin B, and/or itraconazole).
Chemotherapy lowers the white blood cell count or weakens the immune system for a long time. This puts the patients at a high risk of getting a serious fungal infection of the internal organs or blood. One of these infections is caused by a mold called Aspergillus and can be life threatening. Usually doctors give preventive antifungal therapy to try to lower the risk of this infection. Despite this, patients are still at risk of getting fungal infection. This study is thus designed to test Galactomannan - a component of cell wall of Aspergillus and hence detect and treat fungal infection early.
Combination therapy of caspofungin and amphotericin B could be a useful treatment option in invasive fungal disease, but before it can be routinely recommended; carefully controlled and well-designed randomized clinical trials are needed.
A Phase II/III randomized double-blind study comparing the safety and the efficacy of a weekly administration of 25 mg nebulized AmBisome with nebulized placebo solution to prevent invasive pulmonary aspergillosis in neutropenic hemato-oncologic patients.
A fixed dosage regimen of voriconazole is routinely used for prophylaxis of aspergillosis in lung transplant patients at our institution. We hypothesize that use of a fixed dosage voriconazole regimen leads to large degree of variability in drug exposure among lung transplant patients and consequently, therapeutic failures or toxicity. This is a three part study which will examine plasma and lung voriconazole concentrations achieved with the prophylactic regimen and assess for a correlation between these concentrations with efficacy and toxicity. We aim to conduct an initial pilot study in 12 lung transplant patients to characterize the pharmacokinetic profile of voriconazole with both intravenous and oral doses. The data gathered from the pilot pharmacokinetic study will then be utilized to correlate trough concentrations with total voriconazole drug exposure as measured by area under the plasma concentration versus time curve (AUC). Additionally, trough concentrations will be followed over nine weeks of the prophylactic treatment period in a larger cohort of patients to determine maintenance of consistency in trough concentrations and whether the plasma concentrations are predictive of efficacy and toxicity. Voriconazole lung concentrations will be measured in a pilot study of 12 patients who undergo a bronchoscopy procedure as part of their standard medical care in order to determine the relationship between plasma and lung concentrations. The information obtained from this three phase study will be utilized to characterize the pharmacokinetics of voriconazole in lung transplant patients. Further, it will be used to define an optimal therapeutic voriconazole regimen that will be individualized to target specific concentrations in the lung and plasma to maximize efficacy and minimize toxicity
Aspergillus is a fungus found in soil, on farms and on construction sites. In those whose immune system is impaired it causes severe infection. The people who are particularly at high-risk of infection with Aspergillus (which is called Invasive Aspergillosis)are those with acute leukaemia who are having chemotherapy and those post bone marrow transplantation. Currently 15% of those at high-risk develop Invasive Aspergillosis and 60-90% of those with Invasive Aspergillosis die. The main reason for this high death rate is that our current diagnostic tests are not good at detecting infection or often only detect the infection at advanced stages when treatment is ineffective. Because of the limitations of current diagnostic tests the current practice is to give empiric antifungal therapy (EAFT) early to treat suspected Invasive Aspergillosis. However studies have demonstrated that this therapy has only resulted in a minor reduction in the mortality rates and it also causes significant drug toxicity. It is a suboptimal treatment modality. New tests have recently been developed to diagnose Invasive Aspergillosis. These tests are for the detection of an Aspergillus protein in blood and for the detection of Aspergillus DNA in blood. Available data suggests that these new tests make an early diagnosis and seem to be able to monitor responses to treatment. However no study has been reported to date which demonstrates that the use of these tests can impact on important patient outcomes. This trial is being performed to determine whether the use of the new diagnostic tests to guide antifungal therapy will help improve treatment of Invasive Aspergillosis, reduce drug toxicity and reduce the death rate in the high-risk patients as compared with the current standard method of diagnosis and treatment with EAFT.
