Posaconazole vs Standard Azole (FLU/ITRA) Therapy for Prophylaxis of Invasive Fungal Infections (IFIs) among High-Risk Neutropenic Patients: Results …

2005

Abstract Background: Patients with severe and prolonged neutropenia are at high-risk of developing life-threatening IFIs. Despite current treatment option, IFIs are difficult to treat and frequently associated with high mortality rates. Antifungal prophylaxis has shown benefits in high-risk populations and is a standard practice in many institutions. We compared Posaconazole (POS), a new broad-spectrum triazole, vs Standard Azoles for the prevention of IFIs in patients with a new diagnosis or first relapse of acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) being treated with intensive chemotherapy. Methods: Patients in this randomized, evaluator-blinded, active controlled…

Amphotericin B Penetrates into the Central Nervous System through Focal Disruption of the Blood-Brain Barrier in Experimental Hematogenous Candida Me…

2019

Hematogenous Candida meningoencephalitis (HCME) is a life-threatening complication of neonates and immunocompromised children. Amphotericin B (AmB) shows poor permeability and low cerebrospinal fluid (CSF) concentrations, but is effective in treatment of HCME. In order to better understand the mechanism of CNS penetration of AmB, we hypothesized that AmB may achieve focally higher concentrations in infected CNS lesions. An in vitro BBB model was serially infected with C. albicans. Liposomal AmB (LAMB) or deoxycholate AmB (DAMB) at 5 μg/ml were then provided, vascular and CNS compartments were sampled 4h later. For in vivo correlation, rabbits with experimental HCME received a single dose of…

Posaconazole vs. Fluconazole or Itraconazole Prophylaxis in Patients with Neutropenia

2007

Patients with neutropenia resulting from chemotherapy for acute myelogenous leukemia or the myelodysplastic syndrome are at high risk for difficult-to-treat and often fatal invasive fungal infections.In this randomized, multicenter study involving evaluators who were unaware of treatment assignments, we compared the efficacy and safety of posaconazole with those of fluconazole or itraconazole as prophylaxis for patients with prolonged neutropenia. Patients received prophylaxis with each cycle of chemotherapy until recovery from neutropenia and complete remission, until occurrence of an invasive fungal infection, or for up to 12 weeks, whichever came first. We compared the incidence of prove…

Fungal Infections of the Central Nervous System in Children.

2017

Although uncommon in children, fungal infections of the central nervous system can be devastating and difficult to treat. A better understanding of basic mycologic, immunologic, and pharmacologic processes has led to important advances in the diagnosis and management of these diseases, but their mortality rates remain unacceptably high. In this focused review, we examine the epidemiology and clinical features of the most common fungal pathogens of the central nervous system in children and explore recent advances in diagnosis and antifungal therapy.
