In preventing invasive fungal disease (IFD) in patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS), clinical trials demonstrated efficacy of posaconazole over fluconazole and itraconazole. However, effectiveness of posaconazole has not been investigated in the United States in real-world setting outside the environment of controlled clinical trial. We performed a single-center, retrospective cohort study of 130 evaluable patients ≥18 years of age admitted to Duke University Hospital between 2004 and 2010 who received either posaconazole or fluconazole as prophylaxis during first induction or first reinduction chemotherapy for AML or MDS. The primary endpoint was possible, probable, or definite breakthrough IFD. Baseline characteristics were well balanced between groups, except that posaconazole recipients received reinduction chemotherapy and cytarabine more frequently. IFD occurred in 17/65 (27.0%) in the fluconazole group and in 6/65 (9.2%) in the posaconazole group (P = 0.012). Definite/probable IFDs occurred in 7 (10.8%) and 0 patients (0%), respectively (P = 0.0013). In multivariate analysis, fluconazole prophylaxis and duration of neutropenia were predictors of IFD. Mortality was similar between groups. This study demonstrates superior effectiveness of posaconazole over fluconazole as prophylaxis of IFD in AML and MDS patients. Such superiority did not translate to reductions in 100-day all-cause mortality.

Background: The prevention of invasive fungal infections (IFIs) is crucial for paediatric haemato-oncological patients. This study evaluates the clinical efficacy and side-effects of posaconazole and liposomal amphotericin B (L-AmB) as primary prophylaxis.
Materials And Methods: This cohort study included patients aged 3 months to 21 years who received posaconazole or L-AmB (5 mg/kg twice weekly) as prophylaxis from January 2017 to March 2022 at the Hemato-oncological Pediatric Unit, University Hospital of Padua, Italy.

Background: BCL-2 was the first gene identified to have antiapoptotic effects, and venetoclax is an oral selective BCL-2 inhibitor, which has great potential in the treatment of patients with acute myeloid leukemia (AML) who are not candidates for intensive therapy. Notably, posaconazole, an oral antifungal drug, is also a strong factor that can affect blood venetoclax concentrations. To the best of our knowledge, the relationship between BCL-2 expression, posaconazole, and venetoclax, as well as their influence on treatment efficacy and the prognosis of patients with AML, has not been reported.

Background: Mucormycosis is an opportunistic fungal infection which is associated with poor prognosis. Only a few antifungals are available in the arsenal against mucormycosis. The global guidelines for diagnosing and managing mucormycosis recommend high doses of liposomal amphotericin B (LAmB) as the first-line treatment.

Introduction The cushion effect of soft liners serves to distribute the mastication forces and stresses more evenly, along with absorbing energy. Instead, soft liners can act as a nidus for microbial growth, especially Candida species. An accumulation of these fungi is a problem encountered during the clinical use of them, especially in immunocompromised individuals.

species, the leading cause of dermatophytosis globally, are increasingly resistant to antifungal treatments, concerns about effective management strategies. In light of the absence of established resistance criteria for terbinafine and azoles, coupled with a dearth of research on resistance mechanisms in , antifungal susceptibility and drug resistance gene diversity were analyzed across 64 , 65 , and 2 isolates collected in China between 2001 and 2024 and 101 published strains. Analyses of the minimum inhibitory concentrations (MICs) of terbinafine, itraconazole, voriconazole, posaconazole, and isavuconazole revealed a concerning increase in with terbinafine resistance, including two novel isolates from China.
