Abstract Background Isavuconazole (ISA) is a newer triazole which has activity against most mold species and has been utilized for prophylaxis as well as treatment in patients with hematologic malignancies (HM) and hematopoietic stem cell transplant (HSCT). However, several studies have documented breakthrough invasive fungal infections (bIFIs). Thus, we conducted a systematic review and meta-analysis to investigate the incidence of bIFIs among...

Isavuconazole is first-line treatment of invasive aspergillosis. Therapeutic drug monitoring (TDM) is deemed not necessary, since most patients reached therapeutic levels (>1 mg/L) in large studies. Low levels were reported in some critically ill patients admitted to the ICU. The aim was to compare isavuconazole levels between critically ill and non-critically ill patients.Retrospective analysis of data from all patients treated with standard-dose isavuconazole between 1 January 2019 and...

Invasive fungal disease (IFD) remains a significant cause of morbidity and mortality in children undergoing transplantation. There is a growing armamentarium of novel antifungal agents recently approved for use or in late stages of clinical development. The overarching goal of this review is to discuss the mechanisms of action, spectrum of activity, stage of development, and pediatric-specific data for the following agents: encochleated amphotericin B deoxycholate, fosmanogepix,...

Invasive fungal infections are a strong contributor to healthcare costs, morbidity and mortality, especially amongst hospitalized patients. Historically, Candida was responsible for approximately 15% of all nosocomial bloodstream infections. In the past 10 years, the epidemiology of Candida species has altered, with increasing prevalence of resistant species. With rising fungal resistance, especially in Candida spp., the demand for novel antifungal therapies has exponentially increased over...

Abstract Background Isavuconazole (ISA) is a newer antifungal used in patients with history of hematologic malignancies and hematopoietic transplant and cellular therapies (HM/TCT). Although it has a more favorable side‐effect profile, breakthrough invasive fungal infections (bIFIs) while on ISA have been reported. Methods In this single‐center retrospective study evaluating HM/TCT patients...

Amphotericin B is the gold standard treatment for severe mycoses. A new orally delivered, less-toxic formulation of amphotericin has been developed.In our randomized clinical trial, we tested oral lipid nanocrystal (LNC) amphotericin B (MAT2203, Matinas Biopharma) vs intravenous (IV) amphotericin for human immunodeficiency virus–associated cryptococcal meningitis in 4 sequential cohorts. Two pilot cohorts assessed safety and tolerability (n = 10 each), and 2 cohorts assessed efficacy...

Background: Appropriate use of antimicrobials for hematologic malignancy, hematopoietic stem cell transplant recipients, and other cellular therapies is vital, with infection causing significant morbidity and mortality in this unique population of immunocompromised hosts. However, often in this population the choice and management of antimicrobial therapy is complex. When selecting an antimicrobial agent, key considerations include the need for dose adjustments due to renal or hepatic...

Antifungal prophylaxis can prevent invasive fungal diseases (IFDs) in high-risk, immunocompromised patients. This study assessed real-world use of mold-active triazoles (MATs) for the prevention of IFDs.This subgroup analysis of a multicenter, observational, prospective registry in the US from March 2017 to April 2020 included patients who received MATs for prophylaxis (isavuconazole, posaconazole, and voriconazole) at study index/enrollment. The primary objective was to describe patient...

Coccidioidomycosis is a fungal infection with a range of clinical manifestations. Currently used antifungal agents exhibit variable efficacy and toxicity profiles necessitating evaluation of additional therapeutic options. Improvement was observed in the majority of patients treated with isavuconazole, with clinical failures observed only in those with coccidioidal meningitis.

Empiric antifungal therapy is considered the standard of care for high-risk neutropenic patients with persistent fever. The impact of a preemptive, diagnostic-driven approach based on galactomannan screening and chest computed tomography scan on demand on survival and on the risk of invasive fungal disease (IFD) during the first weeks of high-risk neutropenia is unknown.Patients with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) and allogeneic hematopoietic cell transplant...

Objectives Voriconazole therapeutic drug monitoring (TDM) is recommended based on retrospective data and limited prospective studies. This study aimed to investigate whether TDM-guided voriconazole treatment is superior to standard treatment for invasive aspergillosis. Methods A multicentre (n = 10), prospective, cluster randomised, crossover clinical trial was performed in haematological patients aged ≥18 years treated with voriconazole. All patients received standard voriconazole dose at...

In recent years, advancements in the treatment landscape for hematological malignancies, such as acute myeloid leukemia and acute lymphoblastic leukemia, have significantly improved disease prognosis and overall survival. However, the treatment landscape is changing and the emergence of targeted oral therapies and immune-based treatments has brought forth new challenges in evaluating and preventing invasive fungal diseases (IFDs). IFD disproportionately affects immunocompromised hosts,...

Decisions to stop antifungal treatment are based on poorly defined treatment responses and immune reconstitution and experts’ opinions. More evidence is needed to determine the optimal duration of treatment of IMI. Well designed, easy to use, and realistic algorithms to help clinicians decide when to stop antifungal treatment are urgently needed.

Background Invasive fungal infections (IFIs) are a common infectious complication during the treatment of acute myeloid leukemia (AML), high-risk myelodysplastic syndrome (MDS) or post hematopoietic cell transplantation (HCT). For these patients, the National Comprehensive Cancer Network recommends posaconazole or voriconazole for IFI prophylaxis. In clinical practice, however, there has been increased use of isavuconazole due to favorable pharmacokinetic and pharmacodynamic parameters...

Posaconazole, a triazole antifungal commonly used for the treatment and prevention of invasive fungal infections, is available in IV, oral suspension and oral delayed-release (DR) tablet formulations.1–3 Of the oral formulations, the DR tablet is favoured owing to its superior bioavailability, once-daily dosing and reliable absorption regardless of gastric acidity.4 Even when dosed appropriately, posaconazole oral solution often does not achieve therapeutic levels.5 This complicates...

A significant proportion of patients with Rhino-orbito-cerebral mucormycosis (ROCM) develop oroantral fistulas. Due to the unclear efficacy of crushed delayed-release posaconazole tablets (DRPT) via nasogastric tube in this group of patients, clinicians often use inferior alternatives like posaconazole suspension. In this prospective study, we report good plasma concentrations (median, 2,639 ng/mL; interquartile range [IQR], 1,690 to 3,575 ng/mL; and range, 1,004 to 4,835ng/mL) and complete...

Most invasive fungal infections are opportunistic in nature but the epidemiology is constantly changing, with new risk groups being identified. Neutropenia is a classical risk factor for fungal infections, while critically ill patients in the ICU are now increasingly at risk of yeast and mould infections. Factors to be considered when choosing antifungal treatment include the emergence of rarer fungal pathogens, the risk of resistance to azoles and echinocandins and the possibility of...
