Filter by: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.
Invasive fungal infections (IFI) remain the major cause of death among neutropenic patients receiving chemotherapy for leukemia, or submitted to stem cell transplantation. Patients with a history of invasive fungal infection (IFI) are at high risk of developing relapse and fatal complications. Prompt intensive antifungal therapy, have improved responses and survival, allowing an increase of antifungal treatments, including secondary antifungal prophylaxis. Few studies have addressed the role of previous IFI in the feasibility of stem cell transplant, or the secondary prophylaxis with antifungal drugs in preventing recurrence of infection after transplantation. However, given the lack of prospective studies, the role of secondary antifungal prophylaxis remains unclear. Itraconazole is a wide-spectrum triazole antifungal agent active against Candida albicans, non-albicans, Aspergillus spp., Blastomyces dermatitidis, Blastomyces coccidioides, Cryptococcus neoformans, Sporothrix schenkii, Paracoccidioides brasiliensis, Histoplasma spp. and various kinds of yeast fungi and mycetes. The role of itraconazole IFI prophylaxis treatment has been proved by many interventional studies. In this prospective, multicentric study of secondary prophylaxis, itraconazole will be given at standard dose to patients undergoing allogeneic stem cell transplantation or chemotherapy with prior invasive fungal infection, to assess the efficacy and safety of itraconazole secondary prophylaxis.
Voriconazole, a newer triazole-derivative, has become the drug of choice for many invasive fungal infections, including invasive Aspergillosis. Recently, therapeutic drug monitoring of voriconazole has been issued because of wide variations and unpredictability of voriconazole blood concentration. The objective of this study is 1) to characterize the pharmacokinetics of voriconazole in ICU patients on voriconazole prophylaxis or treatment, and 2) to develop and evaluate the prediction and adjustment models for voriconazole plasma levels.
Multiple factors are associated with a large variability in voriconazole exposure following standard dose administration, such as non-linear saturable pharmacokinetics, drug-drug interactions, liver disease, patient age, and genetic polymorphism of the metabolic enzymes. Voriconazole is extensively metabolized by the human hepatic enzymes, primarily mediated by CYP2C19. The polymorphisms account for a relatively large portion of inter-individual variance observed in voriconazole plasma concentrations. However, there are limited data on the relationships between voriconazole blood levels and clinical outcomes or safety in Asian populations. The purpose of this study is to investigate the relationships of voriconazole blood levels with genetic polymorphism, safety, and clinical outcomes in immunocompromised patients with invasive pulmonary aspergillosis.
The objective of this study proposal is to determine whether pharmacologic optimization of voriconazole by means of therapeutic drug monitoring (TDM) results in improved patient outcomes (efficacy and safety) and is more cost-effective compared to the current standard of care.
The purpose of this study is to assess the cut-off value of GM/G test in Chinese patients after hematopoietic stem cell transplantation, and evaluate GM/G test and real-time PCR for diagnosis of IFI in Chinese patients.
The purpose of this study is to compare the efficacy and safety of isavuconazole versus voriconazole in the treatment of patients with invasive aspergillosis.
