Abstract
Machine learning models are increasingly used in the medical domain to study the association between risk factors and diseases to support practitioners in understanding health outcomes. In this paper, we showcase the use of machine-learned staged tree models for investigating complex asymmetric dependence structures in health data. Staged trees are a specific class of generative, probabilistic graphical models that formally model asymmetric conditional independence and non-regular sample spaces. An investigation of the risk factors in invasive fungal infections demonstrates the insights staged trees provide to support medical decision-making.

Performance of rapid on-site evaluation of touch imprints of bronchoscopic biopsies or lung tissue biopsies for the diagnosis of invasive pulmonary filamentous fungi infections in non-neutropenic patients. J Clin Microbiol 2024; 62:e0047924.

Abstract
The diagnosis of invasive pulmonary fungal disease depends on histopathology and mycological culture; there are few studies on touch imprints of bronchoscopic biopsies or lung tissue biopsies for the diagnosis of pulmonary filamentous fungi infections. The purpose of the present study was to explore the detection accuracy of rapid on-site evaluation of touch imprints of bronchoscopic biopsies or lung tissue biopsies for the filamentous fungi, and it aims to provide a basis for initiating antifungal therapy before obtaining microbiological evidence. We retrospectively analyzed the diagnosis and treatment of 44 non-neutropenic patients with invasive pulmonary filamentous fungi confirmed by glactomannan assay, histopathology, and culture from February 2017 to December 2023. The diagnostic positive rate and sensitivity of rapid on-site evaluation for these filamentous fungi identification, including diagnostic turnaround time, were calculated. Compared with the final diagnosis, the sensitivity of rapid on-site evaluation was 81.8%, and the sensitivity of histopathology, culture of bronchoalveolar lavage fluid, and glactomannan assay of bronchoalveolar lavage fluid was 86.4%, 52.3%, and 68.2%, respectively. The average turnaround time of detecting filamentous fungi by rapid on-site evaluation was 0.17 ± 0.03 hours, which was significantly faster than histopathology, glactomannan assay, and mycological culture. A total of 29 (76.3%) patients received earlier antifungal therapy based on ROSE diagnosis and demonstrated clinical improvement. Rapid on-site evaluation showed good sensitivity and accuracy that can be comparable to histopathology in identification of pulmonary filamentous fungi. Importantly, it contributed to the triage of biopsies for further microbial culture or molecular detection based on the preliminary diagnosis, and the decision on early antifungal therapy before microbiological evidence is available.

Abstract
Background Recently, increasing focus on patient input into research and healthcare improvements has fostered expanded patient-centered advocacy efforts. This first pan-fungal disease summit, part of the MYCology Advocacy, Research, & Education effort, brought together patients, caregivers, and mycology experts to better document patient experiences with invasive fungal disease (IFD) and establish priorities for mycology education, advocacy, and research. Methods Patients who had suffered from IFD, their caregivers, clinicians, industry representatives, government officials, and patient advocacy professionals were invited. Patients and caregivers shared their stories and struggles with IFD. Breakout sessions separated mycology experts from patients and caregivers for further discussions to identify commonalities and perceived gaps and to formulate recommendations. The 2 groups then reconvened to develop consensus recommendations. Results IFD patients and their caregivers shared experiences reflecting the typically lengthy prediagnosis, acute treatment, long-term treatment, and posttreatment recovery stages of IFD. They reported substantial physical, psychological, and financial burdens associated with the IFD experience, particularly related to delayed diagnoses. They reaffirmed a need for coordinated patient-centered education, peer support, and advocacy to document the burden of serious fungal infections. Mycology experts discussed strategies to address gaps in the mycology field, such as insufficient training, inadequate workforce support, and a need to partner more with patient groups. Conclusions A summit involving patients with IFD, family caregivers, and mycology experts identified a substantial nonclinical burden of disease associated with IFD. Patients and mycology experts prioritized several goals for education, advocacy, and research to raise awareness of IFD and improve outcomes.

Abstract
Invasive fungal infections (IFIs) are common and life-threatening complications in post-hematopoietic stem cell transplantation (post-HSCT) recipients, Severe IFIs can lead to systemic infection and organ damage, which results in high mortality in HSCT recipients. With the development of the field of fungal infection diagnosis, more and more advanced non-culture diagnostic tools have been developed, such as glip biosensors, metagenomic next-generation sequencing, Magnetic Nanoparticles and Identified Using SERS via AgNPs+ , and artificial intelligence-assisted diagnosis. The advanced diagnostic approaches contribute to the success of HSCT and improve the overall survival of post-HSCT leukemia patients by supporting therapeutical decisions. This review provides an overview of the characteristics of two high-incidence IFIs in post-HSCT recipients and discusses some of the recently developed IFI detection technologies. Additionally, it explores the potential application of cationic conjugated polymer fluorescence resonance energy transfer (CCP-FRET) technology for IFI detection. The aim is to offer insights into selecting appropriate IFI detection methods and gaining an understanding of novel fungal diagnostic approaches in laboratory settings.

Abstract
INTRODUCTION Invasive fungal infections (IFI) are a group of life-threatening diseases associated with significant morbidity, mortality and high healthcare costs. Some modern management programs known as AFS (antifungal stewardship programs) have now been developed. The purpose of this systematic review is to evaluate the different declinations of antifungal stewardship programs (AFPs). METHODS Articles were systematically reviewed using the PRISMA checklist 2020. EMBASE and MEDLINE/PubMED were searched using the term "antifungal stewardship" (2012-2022 data) on 2 January 2023. Eligible studies were those that described an AFS and included an intervention, performance evaluation and outcome measures. RESULTS A total of 22/796 studies were included. Approximately two-thirds (16) were published between 2018 and 2022. 16 (72.7%) stated a minimal complete AFS team. 12 (54.5%) adopted a non-compulsory AFS approach, 6(27.3%) had an Educational AFS and 4(18.2%) a compulsory AFS. Cost analyses of 12 studies showed a decrease for 7 (31.8%) compared to an increase for 5 (22.7%). In terms of outcomes, 18 studies showed a lower (10;45.5%) or the same (8;36.4%) pre-post intervention mortality rate. CONCLUSION AFS programs seem to be related to lower costs and better outcomes and should thus be implemented in tandem with antimicrobial stewardship programs.

Abstract
BACKGROUND The global burden of invasive fungal infections (IFIs) has shown an upsurge in recent years due to the higher load of immunocompromised patients suffering from various diseases. The role of early and accurate diagnosis in the aggressive containment of the fungal infection at the initial stages becomes crucial thus, preventing the development of a life-threatening situation. With the changing demands of clinical mycology, the field of fungal diagnostics has evolved and come a long way from traditional methods of microscopy and culturing to more advanced non-culture-based tools. With the advent of more powerful approaches such as novel PCR assays, T2 Candida, microfluidic chip technology, next generation sequencing, new generation biosensors, nanotechnology-based tools, artificial intelligence-based models, the face of fungal diagnostics is constantly changing for the better. All these advances have been reviewed here giving the latest update to our readers in the most orderly flow. MAIN TEXT A detailed literature survey was conducted by the team followed by data collection, pertinent data extraction, in-depth analysis, and composing the various sub-sections and the final review. The review is unique in its kind as it discusses the advances in molecular methods; advances in serology-based methods; advances in biosensor technology; and advances in machine learning-based models, all under one roof. To the best of our knowledge, there has been no review covering all of these fields (especially biosensor technology and machine learning using artificial intelligence) with relevance to invasive fungal infections. CONCLUSION The review will undoubtedly assist in updating the scientific community's understanding of the most recent advancements that are on the horizon and that may be implemented as adjuncts to the traditional diagnostic algorithms.

Abstract
Vaccines are one of the most effective public health tools to prevent and manage infectious diseases. Since the first clinical use of vaccines in the late 18th century, many vaccines have been successfully developed to combat bacterial and viral infections, including the most recent Coronavirus Disease 2019 (COVID-19) pandemic. However, there remains no vaccine that is clinically available to treat or prevent invasive fungal diseases, including cryptococcal meningoencephalitis. This fungal disease is uniformly fatal without treatment and has a global mortality rate of over 70%. Despite a dire need for an effective cryptococcal vaccine, there are many scientific and economic challenges to overcome prior to making it a reality. Here, we discuss some of these challenges as well as steps that the community is taking for commercialization of effective cryptococcal vaccines.

Abstract
OBJECTIVES Patients with haematologic malignancies are at high risk of developing invasive fungal infections (IFIs). Current guidelines recommend the use of azoles for IFI prophylaxis; however, in many clinical situations, antifungal prophylaxis is used off-label. We conducted a systematic literature review to provide haematologists with the available evidence on the effectiveness and safety of isavuconazole in IFI prophylaxis in interventional and real-world, observational studies. METHODS Embase, MEDLINE and Cochrane Library databases, and relevant conference proceedings and clinical trial registries, were searched for studies on the effectiveness and safety of isavuconazole prophylaxis in adults at high risk of IFIs. Studies were assessed for inclusion and risk of bias. RESULTS Nine studies were eligible for inclusion in the review, eight of which were in haematologic populations (patients undergoing haematopoietic stem cell transplantation or with acute myeloid leukaemia or myelodysplastic syndromes; n = 5) or included haematologic populations (n = 3). Evidence from these studies suggests isavuconazole is effective for IFI prophylaxis in the haematologic setting. However, the studies frequently lacked safety data, most were based on small patient populations from single centres and risk of bias could not be assessed for five studies. DISCUSSION These findings provide evidence for isavuconazole as an alternative azole for prophylaxis in high-risk populations. Limitations include lack of applicability of risk of bias assessment tools, level of filtering applied in the search strategy and focus on English-language publications. CONCLUSION Isavuconazole may be an effective azole for IFI prophylaxis in high-risk haematologic populations, although further studies are needed.

Abstract
Background
Paediatric intensive care units (PICUs) are high-risk settings for healthcare-associated infections. Invasive fungal infection
(IFI) is one of the common causes of healthcare-associated infections.
Objectives
To describe the prevalence and short-term outcomes of children with IFI, and to offer a basis for the efficient prevention and
treatment of IFI.
Methods
A retrospective study was conducted in children under the age of 12 years over a two-year period. Participants were categorised
according to pre-defined microbiology criteria into IFI if they had a positive culture from blood or other sterile sites. Data collected included
demographics, invasive procedures, length of stay and mortality.
Results
One thousand and forty-two children were admitted during the study period. Of the total, 56.8% (n=592) were male. Median
length of stay was 18 days (mean±SE 18.6±8.9). IFI was identified in 35 cases per 1 000 admissions, with 77.7% of these infants under
the age of one year. The mean length of stay was 18.6 days compared with 7.5 days for children with bacterial infections. The in-hospital
mortality for invasive fungal infection was 36% compared with 16% for all admissions. Findings confirmed that colonisation was more
prevalent than IFI.
Conclusion
IFIs are common among infants, and these patients have a higher mortality rate and prolonged hospital stay. Therefore we
recommend early diagnosis and timely treatment with high-performance antifungal drugs to improve the prognosis in children with IFI.

Voriconazole in hematopoietic stem cell transplantation and cellular therapies: Real-world usage and therapeutic level attainment at a major transplant center. Transplant Cell Ther 2022; 28:511.e1-511.e10. [PMID: 35623614 DOI: 10.1016/j.jtct.2022.05.030] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/17/2022] [Accepted: 05/18/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Voriconazole (VCZ) was one of the first mold-active triazoles available; however, its current use among high-risk hematology populations is unknown as the uptake of posaconazole (PCZ) and isavuconazole (ISZ) increases. OBJECTIVES We evaluated the usage and therapeutic level attainment of VCZ in hematopoietic cell transplant (HCT) and chimeric antigen receptor T cell (CAR-T) therapy patients at our cancer center. STUDY DESIGN Electronic medical records for all adult HCT or CAR-T patients with an order for VCZ, PCZ or ISV between January 1, 2018, and June 30, 2020 were extracted. Clinical characteristics, VCZ indication, trough VCZ levels, and frequency of VCZ initiation from 6 months pre- to 6 months post HCT/CAR-T infusion in consecutive HCT/CAR-T recipients within the study period (infusion between July 1, 2018, and January 1, 2020) were assessed. The association between relevant clinical characteristics and the attainment of sub- or supratherapeutic levels was also evaluated. RESULTS Of 468 patients prescribed mold-active triazoles, 256 (54.7%) were prescribed VCZ, 324 (69.2%) PCZ, and 60 (12.8%) ISZ; 152/468 (32.5%) treatment regimens were sequentially modified to alternate mold-active triazoles. Among consecutive HCT and CAR-T recipients at our center, evaluated 6 months pre- or post- HCT/ CAR-T, VCZ was commonly initiated pre- or post-allogeneic HCT (102/381, 26.8%), with most use in the first 30 days post stem cell infusion (40/381, 10.5%); VCZ use was less common in autologous HCT (13/276, 4.7%) and CAR-T (10/153, 6.5%). Of 223 VCZ orders that met inclusion for analysis, indications included empiric treatment in 108/223 (48.4%), directed therapy in 25/223 (11.2%), primary prophylaxis in 69/223 (30.9%) and secondary prophylaxis in 21/223 (9.4%). Of 223 eligible VCZ patients, 144 (64.6%) had at least one VCZ level measured during the study period; 75/144 (52.1%) had a therapeutic VCZ level (1.0-5.5mg/L) at the first measurement (median 2.8mg/L [range 0.1 - 13.5]) at a median of 6 days of therapy, with 26.4% subtherapeutic and 21.5% supratherapeutic; 46/88 (52.3%) were therapeutic at the second measurement (2.1mg/L [0.1 - 9.9]) at a median of 17 days of therapy; and 33/48 (68.8%) at the third (2.3mg/L [0.1 - 7.7]) at a median of 29 days. In multivariable analysis of factors associated with sub- or supratherapeutic levels (body mass index ≥30, concurrent omeprazole use, concurrent letermovir use, indication for VCZ, history/timeframe of HCT), the only significant association was lower odds of a supratherapeutic VCZ level among those undergoing HCT within the previous 30 days compared to those without a history of HCT. CONCLUSIONS VCZ continues to remain an important option in the treatment and prevention of invasive fungal infections in an era when alternative oral mold-active triazoles are available. In spite of long-standing experience with VCZ prescribing, therapeutic level attainment remains a challenge.

Abstract
Severe acute respiratory syndrome coronavirus-2 has caused a devastating pandemic lasting for more than a year. To date, 47 million individuals have been infected and 1.2 million individuals have died worldwide. Some of the most important coinfections in patients with coronavirus disease 2019 (COVID-19) are opportunistic invasive fungal infections (OIFIs), which are sometimes not rapidly diagnosed and are often diagnosed after death. Aspergillosis and candidiasis are the most prevalent OIFIs in patients with COVID-19. Mycormycosis, cryptococcosis, and other fungal diseases have also been documented more rarely. This review aimed to summarize factors affecting COVID-19 transmission, prevalence, morbidity, and mortality in Iran as well as to review common OIFIs in patients with COVID-19. Immunological factors, underlying diseases, and social, cultural, and environmental factors can affect COVID-19 transmission. There is a need to improve diagnostic and therapeutic criteria for OIFIs and to optimize management procedures so that patients with OIFIs can receive treatment as rapidly as possible. Screening of patients with confirmed COVID-19 for OIFIs at the treating physician’s discretion could enable early OIFI diagnosis, treatment, and mortality reduction.

Abstract
Chronic pulmonary aspergillosis (CPA) is an emerging disease in patients with common chronic pulmonary diseases (CPDs). While its prevalence is linked to tuberculosis (TB) in endemic countries, epidemiological and prognostic data are lacking in low TB incidence countries. The aim of this study was to describe these features in CPA patients hospitalised in France between 2009 and 2018.We estimated the prevalence and mortality of hospitalised CPA patients using the French nationwide administrative hospital database. We also assessed the association with CPD, thoracic interventions and malnutrition.From 2009 to 2018, 17 290 patients were hospitalised in France for CPA, with an increasing prevalence during this period. Most patients were male (63.5%) with a median age of 65 years at CPA diagnosis, living in farming regions and large cities. The proportion of underlying chronic obstructive pulmonary disease (COPD) and emphysema during the previous 5 years was 44% and 22%, respectively, whereas it was only 3% for both TB and non-TB mycobacterial (NTM) infections. The mortality rates during the first hospitalisation, at 1 year and at 5 years were 17%, 32% and 45%, respectively. In multivariate analysis, mortality rates were increased in patients aged >65 years, male patients and patients with malnutrition, diabetes or lung cancer history. The risk of mortality in patients with COPD or emphysema was higher than in those with previous mycobacterial lung infection.In France, CPA is an emerging infection commonly associated with non-mycobacterial CPD. This shift in the distribution profile of underlying CPD will likely worsen CPA mortality.

Abstract
PURPOSE OF REVIEW This review aims to summarize available guidelines as well as the emerging evidence for the prevention and treatment of invasive fungal diseases in high-risk haematology patients. RECENT FINDINGS Primary mould-active prophylaxis is the strategy used in many centres to manage the risk of invasive fungal disease in high-risk haematology patients, and posaconazole remains the antifungal of choice for most of these patients. Data on the use of other antifungals for primary prophylaxis, including isavuconazole, are limited. There is considerable interest in identifying a strategy that would limit the use of mould-active agents to the patients who are the most likely to benefit from them. In this regard, a recent trial demonstrated that the preemptive strategy is noninferior to the empiric strategy. For primary treatment of invasive aspergillosis, two randomized trials found isavuconazole and posaconazole to be noninferior to voriconazole. Isavuconazole does not appear to require therapeutic drug monitoring. SUMMARY Prophylaxis and treatment of invasive fungal diseases in high-risk haematology patients is a rapidly evolving field. Critical clinical questions remain unanswered, especially regarding the management of suspected invasive fungal diseases breaking through mould-active prophylaxis, and the duration of antifungal therapy for invasive mould infections.

Abstract
OBJECTIVE To examine treatment patterns of real-world antifungal management of patients at high risk of invasive fungal infections (IFI) and evaluate healthcare resource utilization and costs associated with antifungal management of IFIs in Japan. METHODS This retrospective, observational study extracted data from a hospital-based claims database for patients in Japan who either (a) underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT), or (b) were hospitalized with acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) and received chemotherapy during the study period of January 2010 to January 2019. RESULTS 863 patients were included in the allo-HSCT cohort and 4498 patients were included in the AML/MDS cohort. In the allo-HSCT cohort, 91% received more than one antifungal drug during the index hospitalization. In the AML/MDS cohort, approximately 50% received more than one antifungal drug during the index hospitalization. For both the allo-HSCT and AML/MDS cohorts, about 90% of the total cost was attributed to inpatient costs. Of note, both the total cost (the total inpatient and outpatient cost) and the index hospitalization costs were higher in patients treated with multiple antifungal drugs than in those treated with a single antifungal drug during the index hospitalization. Despite being at high IFI risk, 12% of the patients in the AML/MDS cohort did not receive antifungal drugs during the index hospitalization. CONCLUSIONS Most patients with hematologic malignancy and high IFI risk underwent complicated antifungal management requiring use of multiple drugs, and accounted for high healthcare resource utilization and costs.

Abstract
A series of novel 2-oxo-(1-oxo-2,8-diazaspiro[4.5]decane-8-yl)ethylpiperidine carboxamide derivatives were designed, synthesized and characterized by 1H NMR, 13C NMR and HRMS spectroscopy. All eighteen newly prepared compounds were evaluated for their inhibition against chitin synthase (CHS) and antifungal activities in vitro. The enzyme assay revealed that compound 5h showed excellent inhibitory activity against CHS with IC50 value of 0.10 mM, and the compounds 5b, 5d and 5q showed good inhibition against chitin synthase with IC50 values of 0.13 mM, 0.18 mM and 0.15 mM, respectively, while IC50 value of ployoxin B was 0.08 mM. Meanwhile, the others of these compounds exhibited moderate inhibition potency against chitin synthase. The antifungal assay showed compound 5h had excellent antifungal activity compared with the control drugs fluconazole and polyoxin B against these tested strains including C. albicans, A. fumigatus, C. neoformans and A. flavus. Its excellent antifungal activity was consistent with its excellent chitin synthase inhibition. Compound 5k and 5l against C. albicans were comparable with fluconazole, and they showed strong antifungal potency against A. flavus with MIC values of 0.07 mmol/L and 0.13 mmol/L respectively. Compound 5m had similar MIC value against A. fumigatus to fluconazole. The phenomenon that compounds 5b, 5d and 5q that showed good enzymatic inhibition didn't exert good antifungal activity, while compounds 5k, 5l and 5m that showed moderate chitin synthase inhibition exhibited excellent antifungal activity was discussed. Furthermore, the trial of drug combination showed that compounds had synergistic effects or additive effects with fluconazole against tested fungi which also verified that these designed compounds targeted different targets from that of fluconazole. Additionally, the antibacterial trial showed that all synthesized compounds had little potency against tested bacteria strains. These results indicated that the designed compounds were potential chitin synthase inhibitors and had selectively antifungal activities.

Abstract
Background Invasive fungal disease is a life-threatening condition that can be challenging to treat due to pathogen resistance, drug toxicity, and therapeutic failure secondary to suboptimal drug concentrations. Frequent therapeutic drug monitoring (TDM) is required for some anti-fungal agents to overcome these issues. Unfortunately, TDM at the institutional level is difficult, and samples are often sent to a commercial reference laboratory for analysis. To address this gap, the first paper spray-mass spectrometry assay for the simultaneous quantitation of five triazoles was developed. Methods Calibration curves for fluconazole, posaconazole, itraconazole, hydroxyitraconazole, and voriconazole were created utilizing plasma-based calibrants and four stable isotopic internal standards. No sample preparation was needed. Plasma samples were spotted on a paper substrate in pre-manufactured plastic cartridges, and the dried plasma spots were analyzed directly utilizing paper spray-mass spectrometry (paper spray MS/MS). All experiments were performed on a Thermo Scientific TSQ Vantage triple quadrupole mass spectrometer. Results The calibration curves for the five anti-fungal agents showed good linearity (R2 = 0.98-1.00). The measured assay ranges (lower limit of quantification [LLOQ]-upper limit of quantitation [ULOQ]) for fluconazole, posaconazole, itraconazole, hydroxyitraconazole, and voriconazole were 0.5-50 μg/mL, 0.1-10 μg/mL, 0.1-10 μg/mL, 0.1-10 μg/mL, and 0.1-10 μg/mL, respectively. The inter- and intra-day accuracy and precision were less than 25% over the respective ranges. Conclusions We developed the first rapid paper spray-MS/MS assay for simultaneous quantitation of five triazole anti-fungal agents in plasma. The method may be a powerful tool for near-point-of-care TDM aimed at improving patient care by reducing the turnaround time and for use in clinical research.

Abstract
BACKGROUND Invasive fungal infection is a major source of morbidity and mortality. The usage of microbial cell-free DNA for the detection and identification of invasive fungal infection has been considered as a potential alternative to invasive procedures allowing for rapid results. OBJECTIVE This analysis aimed to assess the budget implications of using the Karius® Test in patients suspected of invasive fungal infection in an average state in the USA from a healthcare payer perspective. METHODS The analysis used a decision tree to capture key stages of the patient pathway, from suspected invasive fungal infection to either receiving treatment for invasive fungal infection or being confirmed as having no invasive fungal infection. The analysis used published costs and resource use from a targeted review of the literature. Because of the paucity of published evidence on the reduction of diagnostic tests displaced by the Karius Test, the analysis used a 50% reduction in the use of bronchoscopy and/or bronchoalveolar lavage. The impact of this reduction was tested in a scenario analysis. RESULTS The results of the analysis show that the introduction of the Karius Test is associated with a cost saving of US$2277 per patient; when multiplied by the estimated number of cases per year, the cost saving is US$17,039,666. The scenario analysis showed that the Karius Test only had an incremental cost of US$87 per patient when there was no reduction in bronchoscopy and bronchoalveolar lavage. CONCLUSIONS The Karius Test may offer a valuable and timely option for the diagnosis of invasive fungal infection through its non-invasive approach and subsequent cost savings.

Abstract
OBJECTIVE To evaluate outcomes, healthcare resource utilization, and costs associated with mucormycosis in inpatient settings in Japan. METHODS We performed a systematic literature review, followed by a retrospective database study using hospital health claims for patients in Japan hospitalized with a diagnosis of mucormycosis between January 2010 and January 2019. Outcomes assessed included duration of index hospitalization; index stay mortality; hospital readmission within 30, 60, and 90 days after index hospitalization discharge; drug/treatment utilization and patterns; number of patients examined for mucormycosis during the index hospitalization; and index stay inpatient costs. RESULTS From our systematic literature review of articles describing 133 patients with mucormycosis, mortality in the index hospitalization was 55.6%. From our database study of 126 patients hospitalized for mucormycosis, mortality during the index hospitalization was 35.7% and mean index stay duration was 94 days. Hematologic malignancies were the most common risk factor in the literature review and the most common comorbidity in the database study. During the index stay, 39 patients (31.0%) received liposomal amphotericin B (L-AMB) treatment and 74 patients (58.7%) received other antifungal treatments. Median total inpatient costs for the index hospitalization were equivalent to approximately US$60,945, including US$29,283 in drug costs. CONCLUSIONS This study investigated the healthcare resource utilization and cost of medical resources caused by mucormycosis in Japan. The drug costs for antifungal treatments comprised about half of total inpatient costs. Mucormycosis leads to high mortality, high healthcare resource utilization, and high costs.

Abstract
BACKGROUND Patients undergoing allogeneic stem cell transplantation (aSCT) are at high risk to develop an invasive fungal disease (IFD). Optimisation of antifungal prophylaxis strategies may improve patient outcomes and reduce treatment costs. OBJECTIVES To analyse the clinical and economical impact of using continuous micafungin as antifungal prophylaxis. PATIENTS/METHODS We performed a single-centre evaluation comparing patients who received either oral posaconazole with micafungin as intravenous bridging as required (POS-MIC) to patients who received only micafungin (MIC) as antifungal prophylaxis after aSCT. Epidemiological, clinical and direct treatment cost data extracted from the Cologne Cohort of Neutropenic Patients (CoCoNut) were analysed. RESULTS Three hundred and thirteen patients (97 and 216 patients in the POS-MIC and MIC groups, respectively) were included into the analysis. In the POS-MIC and MIC groups, median overall length of stay was 42 days (IQR: 35-52 days) vs 40 days (IQR: 35-49 days; p = .296), resulting in median overall costs of €42,964 (IQR: €35,040-€56,348) vs €43,291 (IQR: €37,281 vs €51,848; p = .993), respectively. Probable/proven IFD in the POS-MIC and MIC groups occurred in 5 patients (5%) vs 3 patients (1%; p = .051), respectively. The Kaplan-Meier analysis showed improved outcome of patients in the MIC group at day 100 (p = .037) and day 365 (p < .001) following aSCT. CONCLUSIONS Our study results demonstrate improved outcomes in the MIC group compared with the POS-MIC group, which can in part be explained by a tendency towards less probable/proven IFD. Higher drug acquisition costs of micafungin did not translate into higher overall costs.

Efficacy and safety of posaconazole for the prevention of invasive fungal infections in immunocompromised patients: a systematic review with meta-analysis and trial sequential analysis. Sci Rep 2020; 10:14575. [PMID: 32884060 PMCID: PMC7471265 DOI: 10.1038/s41598-020-71571-0] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Accepted: 08/17/2020] [Indexed: 12/13/2022] Open
Abstract
Invasive fungal infections are a potentially life-threatening complication in immunocompromised patients. The aim of this study was to assess the efficacy and safety of posaconazole as compared with other antifungal agents for preventing invasive fungal infections in immunocompromised patients. Embase, CENTRAL, and MEDLINE were searched for randomized conweekmonthtrolled trials (RCTs) up to June 2020. A systematic review with meta-analysis of RCTs was performed using random-effects model. Trial sequential analysis (TSA) was conducted for the primary outcome to assess random errors. A total of five RCTs with 1,617 participants were included. Posaconazole prophylaxis was associated with a significantly lower risk of IFIs (RR, 0.43 [95% CI 0.28 to 0.66, p = 0.0001]) as compared to other antifungal agents. No heterogeneity was identified between studies (I2 = 0%). No significant associations were observed for the secondary outcomes measured, including risk reduction of invasive aspergillosis and candidiasis, clinical failure, all-cause mortality, and treatment-related adverse events, except for infection-related mortality (RR, 0.31 [95% CI 0.15 to 0.64, p = 0.0001]). Subgroup analysis favoured posaconazole over fluconazole for the prevention of IFIs (RR, 0.44 [95% CI 0.28 to 0.70, p = 0.0004]). TSA confirmed the prophylactic benefit of posaconazole against IFIs. Posaconazole is effective in preventing IFIs among immunocompromised patients, particularly those with hematologic malignancies and recipients of allogenic hematopoietic stem cell transplantation.

A population-based analysis of attributable hospitalisation costs of invasive fungal diseases in haematological malignancy patients using data linkage of state-wide registry and costing databases: 2009-2015. Mycoses 2019; 63:162-171. [PMID: 31715052 DOI: 10.1111/myc.13033] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2019] [Revised: 10/23/2019] [Accepted: 10/26/2019] [Indexed: 12/01/2022]
Abstract
BACKGROUND Invasive fungal diseases (IFD) are associated with significant treatment-related costs in patients with haematological malignancies (HM). OBJECTIVES The objectives of this study were to characterise the gross and attributable hospitalisation costs of a variety of IFD in patients with HM by linking state-wide hospital administrative and costing datasets. PATIENTS/METHODS We linked the Victorian Admitted Episodes Dataset, Victorian Cancer Registry and the Victorian Cost Data Collection from 1 July 2009 to 30 June 2015. IFD cases and uninfected controls were matched 1:1 based on age within ten years, same underlying HM and length of stay prior to IFD diagnosis. The cost difference between surviving cases and controls, indexed to 2019 Australian dollars (AUD) calculated twelve months from IFD diagnosis, was determined using Poisson and negative binomial regression (NBR). RESULTS From 334 matched pairs, the gross hospitalisation cost of cases was AUD$67 277 compared to AUD$51 158 among uninfected controls, associated with an excess median hospitalisation cost of AUD$16 119 (P < .001) attributable to IFD, approximating to USD$11 362 and €10 154 at purchasing power parity. Median attributable costs were highest for patients with invasive aspergillosis (AUD$55 642; P < .001) and mucormycosis (AUD$51 272; P = .043) followed by invasive candidiasis AUD$24 572 (P < .001). No change in median excess attributable costs was observed over the study period (P = .90) Analyses by NBR revealed a 1.36-fold increase (P < .001) in total hospitalisation costs among cases as compared to controls twelve months from IFD diagnosis. CONCLUSION Invasive aspergillosis and mucormycosis have high attributable hospitalisation costs but the overall excess IFD cost of AUD$16 119 is modest, potentially reflecting missed or miscoded fungal episodes arguing for better quality surveillance data at hospital level.

Abstract
BACKGROUND Invasive fungal infection (IFI) is a life-threatening complication of allogeneic hematopoietic stem cell transplantation (HSCT) that is also associated with excess healthcare costs. Current approaches include universal antifungal prophylaxis, preemptive therapy based on biomarker surveillance, and empiric treatment initiated in response to clinical signs/symptoms. However, no study has directly compared the cost-effectiveness of these treatment strategies for an allogeneic HSCT patient population. METHODS We developed a state transition model to study the impact of treatment strategies on outcomes associated with IFIs in the first 100 days following myeloablative allogeneic HSCT. We compared three treatment strategies: empiric voriconazole, preemptive voriconazole (200 mg), or prophylactic posaconazole (300 mg) for the management of IFIs. Preemptive treatment was guided by scheduled laboratory surveillance with galactomannan (GM) testing. Endpoints were cost and survival at 100 days post-HSCT. RESULTS Empiric treatment was the least costly ($147 482) and was equally effective (85.2% survival at 100 days) as the preemptive treatment strategies. Preemptive treatments were slightly more costly than empiric treatment (GM cutoff ≥ 1.0 $147 910 and GM cutoff ≥ 0.5 $148 108). Preemptive therapy with GM cutoff ≥ 1.0 reduced anti-mold therapy by 5% when compared to empiric therapy. Posaconazole prophylaxis was the most effective (86.6% survival at 100 days) and costly ($152 240) treatment strategy with a cost of $352 415 per life saved when compared to empiric therapy. CONCLUSIONS One preemptive treatment strategy reduced overall anti-mold drug exposure but did not reduce overall costs. Prevention of IFI using posaconazole prophylaxis was the most effective treatment strategy and may be cost-effective, depending upon the willingness to pay per life saved.

Abstract
AbstractBackgroundSUper BioAvailability-itraconazole (SUBA®-itraconazole) was introduced into Australia in April 2014 as a substitute for standard itraconazole on the basis of improved bioavailability, tolerance and interpatient variability. Shortly after its introduction, our centre converted to the novel formulation for mould prophylaxis in patients undergoing allogeneic HSCT, autologous HSCT or treatment for haematological malignancies with an intermediate/high risk of invasive fungal infection (IFI).MethodsA single-institution, investigator-initiated retrospective cohort study was conducted between June 2016 and April 2018 to assess therapeutic drug concentrations, safety and tolerability of a standard prophylactic dose of SUBA®-itraconazole.ResultsA total of 74 patients were assessed across 98 admissions with 178 measured itraconazole trough concentrations. The median duration of prophylaxis was 15.5 (1–59) days. No significant correlation was identified between trough concentrations and patient demographics including gender and weight. Drug concentrations were reduced by gastric acid suppression and diarrhoea. Therapeutic itraconazole trough concentrations (≥0.5 mg/L) were achieved at a median of 7 (95% CI = 6–8) days, with 87% of patients achieving therapeutic concentrations at day 14 (expected steady-state). One (1%) proven/probable IFI and 5 (5%) possible breakthrough IFIs were identified. Although adverse events were experienced by 42% of the cohort, only a single event was directly attributable to SUBA®-itraconazole, resulting in change of prophylactic agent.ConclusionsSUBA®-itraconazole achieved rapid therapeutic trough concentrations, was associated with low rates of IFI and was well tolerated in the study population. This formulation should be considered a realistic and safe first-line agent for the prevention of IFIs in those undergoing HSCT and intermediate/high-risk therapy for haematological malignancies.

Abstract
Objectives Voriconazole is the drug of choice for invasive aspergillosis (IA), a leading cause of mortality and morbidity in immunocompromised patients. Prolong intravenous administration of voriconazole is often needed in such patients due to high incidence of oral mucositis and unreliable bioavailability of oral dosage form. Administration of voriconazole through elastomeric pump may facilitate early hospital discharge of clinically stable immunocompromised patients needing prolonged intravenous treatment. Therefore, we investigated the physicochemical stability of voriconazole in one of the commonly used elastomeric pumps at three different temperatures for various time points. Methods A total of 18 elastomeric pumps were prepared and 6 containing 2 mg/mL of voriconazole (3 in 0.9% sodium chloride and 3 in 5% glucose) were stored at either 4°C for 96 hours, 25°C for 4 hours or at 35°C for 4 hours. An aliquot withdrawn immediately before storage (time 0) and at various time points was analysed for chemical stability using high-performance liquid chromatography and for physical stability using visual, pH and microscopic analyses. Results Voriconazole was stable for at least 96 hours, 4 hours and 4 hours at 4°C, 25°C and 35°C, respectively, when admixed with either 0.9% sodium chloride or 5% glucose. No evidence of particle formation, colour change or pH change was observed throughout the study period. Conclusions These findings would allow early hospital discharge using elastomeric intravenous administration of voriconazole in patients in whom oral route of administration is not available.

Abstract
The study presents the echinocandin susceptibility profile of a multi-centre collection of pathogenic yeast isolates from Romanian tertiary hospitals. The 562 isolates were identified using ID32C strips, MALDI-TOF MS and DNA sequencing. Minimal inhibitory concentrations (MICs) of caspofungin (CAS), micafungin (MCA), and anidulafungin (ANI) were assessed and interpreted according to EUCAST guidelines. Minimal fungicidal concentrations (MFC) were determined by plating content from the clear MIC wells. The activity was considered fungicidal at MFC/MIC ≤ 4. The three echinocandins had strongly correlated MICs and high percentages of MIC essential agreement. Most often, MCA had the lowest MICs, followed by CAS and ANI. Against C. parapsilosis and C. kefyr, CAS had the lowest MIC values. The MIC50 values were between 0.03 and 0.25 mg/l, except C. parapsilosis. The MIC90 values were usually one dilution higher. MFCs and MICs were weakly correlated. ANI and MCA had the lowest MFC values. The MFC50 values were between 0.06 and 0.5 mg/l, except C. parapsilosis, C. guilliermondii, and C. dubliniensis. The MFC90 values were usually two dilutions higher. Based on EUCAST breakpoints, 47 isolates (8.4%) were resistant to at least one echinocandin, most often ANI. Most resistant isolates were of C. albicans, C. glabrata, and C. krusei. There were 17 isolates (3%) resistant to echinocandins and fluconazole and most belonged to the same three species. MCA and ANI had the highest rates of fungicidal activity. The high rates of echinocandin resistance and significant multidrug resistance make prophylaxis and empiric therapy difficult.

Abstract
BACKGROUND Identification of an organism is the gold standard for the diagnosis of fungal infection; however, we have previously shown that invasive procedures infrequently lead to a change in management in children with cancer or who have undergone stem cell transplant with suspected respiratory tract invasive fungal infection (RT-IFI). There is also a paucity of data on the cost of RT-IFI in this population. We therefore compared the costs of RT-IFI diagnosed based on CT scan alone versus those who underwent a bronchoalveolar lavage (BAL) or respiratory tract biopsy (RTB). PROCEDURE We collected cost data on patients at a single center undergoing chemotherapy or who were post-hematopoietic stem cell transplant (HSCT) and were suspected of having RT-IFI between 2007 and 2012. Cost data were included for 14 days from the day of their diagnostic CT scan or procedure. RESULTS Cost data were available for 76 patients. Thirty-six patients were diagnosed with suspected RT-IFI based on CT only, and 40 patients underwent BAL or RTB. Costs related to chest X-rays (CXRs), inpatient/intensive care unit (ICU) beds, anesthesia, operating room (OR) time, and procedures were significantly higher in the BAL/RTB group versus CT scan group (all P < 0.01). Costs related to CT scans were significantly higher in the CT scan group (P = 0.0002). Overall costs were significantly higher for patients who underwent BAL or RTB versus CT scan only (P < 0.0001). CONCLUSION Our previous data showed that BAL and RTB infrequently led to a change in management in this population. We now demonstrate that this strategy is costly as well.

Multiplex polymerase chain reaction to diagnose bloodstream infections in patients after cardiothoracic surgery. BMC Anesthesiol 2019; 19:59.

Abstract
Background Sepsis and other infectious complications are major causes of mortality and morbidity in patients after cardiac surgery. Whereas conventional blood culture (BC) suffers from low sensitivity as well as a reporting delay of approximately 48–72 h, real-time multiplex polymerase chain reaction (PCR) based technologies like “SeptiFast” (SF) might offer a fast and reliable alternative for detection of bloodstream infections (BSI). The aim of this study was to compare the performance of SF with BC testing in patients suspected of having BSI after cardiac surgery. Methods Two hundred seventy-nine blood samples from 169 individuals with suspected BSI were analyzed by SF and BC. After excluding results attributable to contaminants, a comparison between the two groups were carried out. Receiver operating characteristic (ROC) curves were generated to determine the accuracy of clinical and laboratory values for the prediction of positive SF results. Results 14.7% (n = 41) of blood samples were positive using SF and 17.2% (n = 49) using BC (n.s. [p > 0.05]). In six samples SF detected more than one pathogen. Among the 47 microorganisms identified by SF, only 11 (23.4%) could be confirmed by BC. SF identified a higher number of Gram-negative bacteria than BC did (28 vs. 12, χ2 = 7.97, p = 0.005). The combination of BC and SF increased the number of detected microorganisms, including fungi, compared to BC alone (86 vs. 49, χ2 = 13.51, p < 0.001). C-reactive protein (CRP) (21.7 ± 11.41 vs. 16.0 ± 16.9 mg/dl, p = 0.009), procalcitonin (28.7 ± 70.9 vs. 11.5 ± 30.4 ng/dl, p = 0.015), and interleukin 6 (IL 6) (932.3 ± 1306.7 vs. 313.3 ± 686.6 pg/ml, p = 0.010) plasma concentrations were higher in patients with a positive SF result. Using ROC analysis, IL-6 (AUC 0.836) and CRP (AUC 0.804) showed the best predictive values for positive SF results. Conclusion The SF test represent a valuable method for rapid etiologic diagnosis of BSI in patients after cardiothoracic surgery. In particular this method applies for individuals with suspected Gram-negative blood stream. Due to the low performance in detecting Gram-positive pathogens and the inability to determine antibiotic susceptibility, it should be used in addition to BC only (Pilarczyk K, et al., Intensive Care Med Exp ,3(Suppl. 1):A884, 2015).

Intravenous and tablet formulation of posaconazole in antifungal therapy and prophylaxis: A retrospective, non-interventional, multicenter analysis of hematological patients treated in tertiary-care hospitals. Int J Infect Dis 2019; 83:130-138. [PMID: 30978465 DOI: 10.1016/j.ijid.2019.04.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 04/03/2019] [Accepted: 04/04/2019] [Indexed: 02/01/2023] Open
Abstract
OBJECTIVES Novel formulations (gastro-resistant tablet and intravenous solution) of posaconazole (POS) have been approved in prophylaxis and therapy of invasive fungal diseases (IFDs). Study aim was to analyze treatment strategies and clinical effectiveness. METHODS We set up a web-based registry on www.ClinicalSurveys.net for documentation of comprehensive data of patients who received novel POS formulations. Data analysis was split into two groups of patients who received novel POS formulations for antifungal prophylaxis (posaconazole prophylaxis group) and antifungal therapy (posaconazole therapy group), respectively. RESULTS Overall, 180 patients (151 in the posaconazole prophylaxis group and 29 in the posaconazole therapy group) from six German tertiary care centers and hospitalized between 05/2014 - 03/2016 were observed. Median age was 58 years (range: 19 - 77 years) and the most common risk factor for IFD was chemotherapy (n = 136; 76%). In the posaconazole prophylaxis group and posaconazole therapy group, median POS serum levels at steady-state were 1,068 μg/L (IQR 573-1,498 μg/L) and 904 μg/L (IQR 728-1,550 μg/L), respectively (P = 0.776). During antifungal prophylaxis with POS, nine (6%) probable/proven fungal breakthroughs were reported and overall survival rate of hospitalization was 86%. The median overall duration of POS therapy was 18 days (IQR: 7 - 23 days). Fourteen patients (48%) had progressive IFD under POS therapy, of these five patients (36%) died related to or likely related to IFD. CONCLUSIONS Our study demonstrates clinical effectiveness of antifungal prophylaxis with novel POS formulations. In patients treated for possible/probable/proven IFD, we observed considerable mortality in patients receiving salvage treatment and with infections due to rare fungal species.

Abstract
Mold infections carry a substantial clinical and economic burden in solid organ transplant (SOT) recipients with a high overall mortality of near 30%. The most important pathogens include Aspergillus, the Zygomycetes, Fusarium, Scedosporium/Pseudallescheria, and the dematiaceous (dark) molds. Risk factors for the infections vary by transplant type but include degree of immune suppression and loss of skin or mucosal integrity. Correct diagnosis usually requires histopathology and/or culture. Management often requires a multidisciplinary team approach with combined antifungal and surgical therapies. This article reviews the epidemiology, risk factors, microbiology, diagnostic, and treatment approach to mold infections in SOT recipients.

Abstract
BACKGROUND Invasive mucormycosis (IM) is a rare invasive fungal infection with a high mortality rate. However, data concerning the clinical and economic burden of IM are scarce. AIM To evaluate the direct treatment costs and additional expenditures of patients with IM. METHODS A retrospective cost-of-illness analysis of cases with IM extracted from FungiScope - Global Registry for Emerging Fungal Infections, accessible through the epidemiological research platform www.ClinicalSurveys.net, was undertaken. Results of patients with IM were compared with those of matched patients with similar underlying conditions based on the German Diagnosis Related Group (G-DRG) coding. FINDINGS Out of 46 patients with probable/proven IM, 31 (67%) patients were male and the median age was 53 years (range 11-88 years). Forty-two patients (92%) had haematological diseases as the most common risk factor. Analysis of cost factors identified antifungal treatment due to IM as the primary cost driver [€22,816, 95% confidence interval (CI) €15,036-32,346], with mean overall direct treatment costs of €53,261 (95% CI €39,660-68,825). Compared with matched patients, patients with IM were treated in hospital for 26.5 additional days (standard deviation 31.8 days; P < 0.001), resulting in mean additional costs of €32,991 (95% CI €21,558-46,613; P < 0.001). Probable IM, as well as absence of chemotherapy, surgical measures due to IM, and antifungal prophylaxis were associated with lower overall costs. Nineteen patients (41.3%) died during hospitalization. CONCLUSION This study demonstrates the considerable healthcare burden of IM. The choice of antifungal agent for treatment of IM had no impact on overall cost.

Abstract
BACKGROUND Invasive fungal infections (IFIs) affect >1.5 million people per year. Nevertheless, IFIs are usually neglected and underdiagnosed. IFIs should be considered as a public-health problem and major actions should be taken to tackle them and their associated costs. Aim To report the incidence of IFIs in four Mexican hospitals, to describe the economic cost associated with IFIs therapy and the impact of adverse events such as acute kidney injury (AKI), liver damage (LD), and ICU stay. METHODS This was a retrospective, transversal study carried-out in four Mexican hospitals. All IFIs occurring during 2016 were included. Incidence rates and estimation of antifungal therapy's expenditure for one year were calculated. Adjustments for costs of AKI were done. An analysis of factors associated with death, AKI, and LD was performed. RESULTS Two-hundred thirty-eight cases were included. Among all cases, AKI was diagnosed in 16%, LD in 25%, 35% required ICU stay, with a 23% overall mortality rate. AKI and LD showed higher mortality rates (39% vs 9% and 44% vs 18%, respectively, p<0.0001). The overall incidence of IFIs was 4.8 cases (95% CI=0.72-8.92) per 1000 discharges and 0.7 cases (95% CI=0.03-1.16) per 1000 patients-days. Invasive candidiasis showed the highest incidence rate (1.93 per 1000 discharges, 95% CI=-1.01 to 2.84), followed by endemic IFIs (1.53 per 1000 discharges 95% CI=-3.36 to 6.4) and IA (1.25 per 1000 discharges, 95% CI=-0.90 to 3.45). AKI increased the cost of antifungal therapy 4.3-fold. The total expenditure in antifungal therapy for all IFIs, adjusting for AKI, was $233,435,536 USD (95% CI $6,224,993 to $773,810,330). CONCLUSIONS IFIs are as frequent as HIV asymptomatic infection and tuberculosis. Costs estimations allow to assess cost-avoidance strategies to increase targeted driven therapy and decrease adverse events and their costs.

Abstract
BACKGROUND/AIM The aim of this article is to study the spectrum, changing prevalence, and predictors for mortality of invasive fungal disease (IFD) in pediatric leukemia in a resource-limited setting. OBSERVATIONS Prevalence was 7% (proven, 69%; probable, 16.4%; possible, 14.6%) and did not differ between acute lymphoblastic leukemia and acute myeloid leukemia. Lungs were frequently involved (46%). Aspergillus was the commonest fungus (47%). Visceral abscesses were frequent with candidiasis as compared with invasive molds (P=0.016). IFD resulted in a prolonged admission (mean, 12.6±2 d; P=0.014) and death (44%) (Aspergillus, 50%; Candida, 50%; Mucor, 34%). Diagnosis of acute myeloid leukemia predicted mortality (P=0.03). CONCLUSIONS IFD was an important cause of treatment related mortality in pediatric leukemia (odds ratio, 8.39). Protocolled use of computed tomography-chest and galactomannan-assay aided diagnosis (P<0.05).

Abstract
Objectives To assess therapeutic levels, safety and tolerability of a novel formulation SUBA-itraconazole (where SUBA stands for SUper BioAvailability) when compared with conventional itraconazole liquid when used as antifungal prophylaxis in patients undergoing allogeneic HSCT or in haematological malignancy patients with an intermediate/high risk of invasive fungal infection (IFI). Methods This was a single-institution, prospective cohort study using a historical control group as the comparator. Results A total of 57 patients were assessed: 27 in the SUBA-itraconazole cohort and 30 in the liquid itraconazole cohort. Therapeutic concentrations were achieved significantly more quickly in the SUBA-itraconazole group: median of 6 (95% CI 5-11) days versus 14 (95% CI 12-21) days in the liquid itraconazole group (P < 0.0001). At day 10, therapeutic concentrations were achieved in 69% (95% CI 44%-81%) of the SUBA-itraconazole group versus 21% (95% CI 7%-33%) of the liquid itraconazole group (P < 0.0001). The mean trough serum concentrations at steady-state of SUBA-itraconazole were significantly higher, with less interpatient variability [1577 ng/mL, coefficient of variation (CV) 35%] versus liquid itraconazole (1218 ng/mL, CV 60%) (P < 0.001). There were two (7.4%) treatment failures in the SUBA-itraconazole group, both due to cessation of therapy for mucositis, compared with seven (23.3%) treatment failures in the liquid itraconazole group, due to subtherapeutic levels (five), mucositis (one) and gastrointestinal intolerance (one) (P = 0.096). Conclusions The use of the SUBA-itraconazole formulation was associated with more rapid attainment of therapeutic levels with less interpatient variability compared with conventional liquid itraconazole when used as IFI prophylaxis in allogeneic HSCT or intermediate-/high-IFI risk haematological malignancy patients.

Abstract
Diagnosis of life-threatening deep-seated infections currently requires invasive sampling of the infected tissue to provide a microbiologic diagnosis. These procedures can lead to high morbidity in patients and add to healthcare costs. Here we describe a novel next-generation sequencing assay that was used to detect pathogen-derived cell-free DNA in peripheral blood of patients with biopsy-proven invasive fungal infections. The noninvasive nature of this approach could provide rapid, actionable treatment information for invasive fungal infections when a biopsy is not possible.

Abstract
Candidemia is a bloodstream fungal infection caused by Candida species and is most commonly observed in hospitalized patients. Even with proper antifungal drug treatment, mortality rates remain high at 40–50%. Therefore, prophylactic or preemptive antifungal medications are currently recommended in order to prevent infections in high-risk patients. Moreover, the majority of women experience at least one episode of vulvovaginal candidiasis (VVC) throughout their lifetime and many of them suffer from recurrent VVC (RVVC) with frequent relapses for the rest of their lives. While there currently exists no definitive cure, the only available treatment for RVVC is again represented by antifungal drug therapy. However, due to the limited number of existing antifungal drugs, their associated side effects and the increasing occurrence of drug resistance, other approaches are greatly needed. An obvious prevention measure for candidemia or RVVC relapse would be to immunize at-risk patients with a vaccine effective against Candida infections. In spite of the advanced and proven techniques successfully applied to the development of antibacterial or antiviral vaccines, however, no antifungal vaccine is still available on the market. In this review, we first summarize various efforts to date in the development of anti-Candida vaccines, highlighting advantages and disadvantages of each strategy. We next unfold and discuss general hurdles encountered along these efforts, such as the existence of large genomic variation and phenotypic plasticity across Candida strains and species, and the difficulty in mounting protective immune responses in immunocompromised or immunosuppressed patients. Lastly, we review the concept of “trained immunity” and discuss how induction of this rapid and nonspecific immune response may potentially open new and alternative preventive strategies against opportunistic infections by Candida species and potentially other pathogens.

Abstract
OBJECTIVES It is not yet established the advantages between amphotericin B lipid complex (ABLC) and liposomal (L-AmB) in patients with invasive fungal infections refractory to usual doses of conventional AmB (d-AmB), previous renal impairment, or unacceptable d-AmB renal toxicity. This systematic review aims to compare ABLC and L-AmB effectiveness and safety outcomes in these subgroups of patients. METHODS The search was performed on Medline, Cochrane Library, EMBASE, and LILACS databases. INCLUSION CRITERIA treatment comparing L-AmB with ABLC; patients who had (i) refractory infection after being treated with d-AmB, (ii) previous renal impairment, or (iii) unacceptable d-AmB toxicity. Two investigators independently screened the search results, assessed trial quality, and extracted data. A total of 1,054 articles were identified in the literature. Among those, eleven were selected for full-text reading and five met the inclusion criteria. RESULTS The five articles included reported on four separate observational studies. Overall, no significant difference was found in clinical relevant outcomes as new-onset dialysis, length of hospital stay, or mortality when comparing both lipid formulations. The studies reported a trend toward lower nephrotoxicity in patients treated with L-AmB. However, the results were imprecise and heterogeneous and the studies presented important methodological biases. CONCLUSIONS The studies included in this systematic review pointed toward less nephrotoxicity events in the L-AmB group. However, due to low quality of evidence and no statistically significant differences in other clinical relevant outcomes, there is no definitive evidence of overall superiority in effectiveness or safety outcomes regarding one lipid formulation or another in this population subgroup.

Abstract
The extensive use of fluconazole (FLC) and other azole drugs has caused the emergence and rise of azole-resistant fungi. The fungistatic nature of FLC in combination with toxicity concerns have resulted in an increased demand for new azole antifungal agents. Herein, we report the synthesis and antifungal activity of novel alkylated piperazines and alkylated piperazine-azole hybrids, their time-kill studies, their hemolytic activity against murine erythrocytes, as well as their cytotoxicity against mammalian cells. Many of these molecules exhibited broad-spectrum activity against all tested fungal strains, with excellent minimum inhibitory concentration (MIC) values against non-albicans Candida and Aspergillus strains. The most promising compounds were found to be less hemolytic than the FDA-approved antifungal agent voriconazole (VOR). Finally, we demonstrate that the synthetic alkylated piperazine-azole hybrids do not function by fungal membrane disruption, but instead by disruption of the ergosterol biosynthetic pathway via inhibition of the 14α-demethylase enzyme present in fungal cells.

Abstract
Diversity in eukaryotic rRNA structure and function offers possibilities of therapeutic targets. Unlike ribosomes of prokaryotes, eukaryotic ribosomes contain species-specific rRNA expansion segments (ESs) with idiosyncratic structures and functions that are essential and specific to some organisms. Here we investigate expansion segment 7 (ES7), one of the largest and most variable expansions of the eukaryotic ribosome. We hypothesize that ES7 of the pathogenic fungi Candida albicans (ES7CA) could be a prototypic drug target. We show that isolated ES7CA folds reversibly to a native-like state. We developed a fluorescence displacement assay using an RNA binding fluorescent probe, F-neo. F-neo binds tightly to ES7CA with a Kd of 2.5 × 10-9 M but binds weakly to ES7 of humans (ES7HS) with a Kd estimated to be greater than 7 μM. The fluorescence displacement assay was used to investigate the affinities of a library of peptidic aminosugar conjugates (PAs) for ES7CA. For conjugates with highest affinities for ES7CA (NeoRH, NeoFH, and NeoYH), the lowest dose needed to induce mortality in C. albicans (minimum inhibitory concentration, MIC) was determined. PAs with the lowest MIC values were tested for cytotoxicity in HEK293T cells. Molecules with high affinity for ES7CA in vitro induce mortality in C. albicans but not in HEK293T cells. The results are consistent with the hypothesis that ESs represent useful targets for chemotherapeutics directed against eukaryotic pathogens.

Cost-Effectiveness of Posaconazole Tablets for Invasive Fungal Infections Prevention in Acute Myelogenous Leukemia or Myelodysplastic Syndrome Patients in Spain. Adv Ther 2017; 34:2104-2119. [PMID: 28808915 PMCID: PMC5599452 DOI: 10.1007/s12325-017-0600-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2017] [Indexed: 01/29/2023]
Abstract
Introduction Posaconazole is superior to fluconazole (FLU) and itraconazole (ITRA) in the prevention of invasive fungal diseases (IFDs) in neutropenic patients with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). A new tablet formulation of posaconazole with improved pharmacokinetic and pharmacodynamic properties compared to posaconazole oral solution has recently been approved. The objective of this study is to estimate the cost-effectiveness of the newly developed posaconazole tablets versus FLU oral suspension or ITRA oral solution for preventing IFDs in high-risk neutropenic patients with AML or MDS and from the perspective of the Spanish National Health System (NHS). Methods A previously validated economic model was used. The probabilities of experiencing an IFD, an IFD-related death or death from other causes over 100 days were based on clinical trial data and input into a decision tree. Surviving patients were entered into a Markov model to calculate total costs, number of IFDs and number of life-years gained per patient over a lifetime horizon in each disease and treatment group. Two health states, alive and dead, were considered. Health effects were discounted using a rate of 3%. Univariate and probabilistic sensitivity analyses were conducted. Results During the first 100 days, posaconazole tablets were associated with a lower risk of IFDs (0.046 vs. 0.111), longer life expectancy (2.92 vs. 2.69 years) and lower total costs (€5906.06 vs. €7847.20 per patient) over the patients’ lifetimes compared to FLU or ITRA treatments. Thus, posaconazole tablets were more effective and less costly than FLU or ITRA. Probabilistic sensitivity analysis indicated that there was a 79.9% probability of posaconazole tablets being cost-saving compared to FLU or ITRA. Conclusion From the Spanish NHS perspective, posaconazole tablets are cost-effective compared to FLU or ITRA in AML or MSD patients with chemotherapy-induced neutropenia and at high risk for IFDs.

Abstract
Patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are at increased risk of invasive fungal infections, especially during the early neutropenic phase and severe graft-versus-host disease. Mold-active prophylaxis should be limited to the highest risk groups. Empiric antifungal therapy for HSCT with persistent febrile neutropenia is associated with unacceptable response rates, unnecessary antifungal therapy, increased risk of toxicity, and inflated costs. Empiric therapy should not be a substitute for detailed work up to identify the cause of fever in such patients. The improved diagnostic performance of serum biomarkers such as galactomannan and β-D-glucan, as well as polymerase chain reaction assays has allowed the development of diagnostic-driven antifungal therapy strategies for high risk patients. Diagnostic-driven approaches have resulted in reduced unnecessary antifungal exposure, improved diagnosis of invasive fungal disease, and reduced costs without increased risk of mortality. The appropriateness of diagnostic-driven antifungal strategy for individual HSCT centers depends on the availability and turnaround times for diagnostics, multidisciplinary expertise, and the local epidemiology of invasive fungal infections. Echinocandins are the treatment of choice for invasive candidiasis in most HSCT recipients. Fluconazole may be used for the treatment of invasive candidiasis in hemodynamically stable patients with no prior azole exposure. The primary treatment of choice for invasive aspergillosis is voriconazole. Alternatives include isavuconazole and lipid formulations of amphotericin. Currently available evidence does not support routine primary combination antifungal therapy for invasive aspergillosis. However, combination salvage antifungal therapy may be considered in selected patients. Therapeutic drug monitoring is recommended for the majority of HSCT recipients on itraconazole, posaconazole, or voriconazole.

Abstract
PURPOSE Overall and specific class trends in systemic antifungal expenditures in various U.S. healthcare settings from 2005 through 2015 were evaluated. METHODS Systemic antifungal expenditures from January 1, 2005, through December 31, 2015, were obtained from the QuintilesIMS National Sales Perspective database, which provides a statistically valid projection of medication purchases from multiple markets throughout the United States. Summary data for total antifungal expenditures over the entire period are reported, as are growth and the percentage change in expenditures from one year to the next. Expenditures were also assessed specifically by year, class, and healthcare setting. Expenditure trends over the study period were assessed using simple linear trend regression models. RESULTS Overall expenditures for the 11-year period were $9.37 billion. The greatest proportion of expenditures occurred in nonfederal hospitals (47.2%) and for triazoles (57.6%). From 2005 through 2015, total expenditures decreased from $1.1 billion to $894 million (-18.8%, p = 0.09); however, expenditures in clinics and retail pharmacies increased (202%, p < 0.01, and 13.8%, p = 0.04, respectively), a trend most pronounced after 2012. Expenditures for flucytosine also increased (968.1%, p < 0.01), particularly in clinics where there was a dramatic 6,640.9% increase (p < 0.01). CONCLUSION From 2005 through 2015, an increase in systemic antifungal expenditures was observed in community settings, despite an overall decrease in total antifungal expenditures in the United States. Large increases in flucytosine expenditures were observed, particularly in the community.

Abstract
INTRODUCTION Inappropriate use of antifungal agents is implicated in the global burden of antifungal resistance, adverse outcomes like persistent infections, unnecessary exposure and increased cost. Data collection from time to time is to be done in order to have a check on the resistance/sensitivity pattern of the commonly prescribed antifungal drugs. AIM To describe the pattern of antifungal drug prescription and administration to patients attending a university hospital in Oman. MATERIALS AND METHODS This was a descriptive, retrospective cross-sectional study conducted at Sultan Qaboos University Hospital (SQUH), a university hospital in Oman that covered the electronic patient's data for a period of one year (January 2013 to December 2013). The study included inpatients and outpatients of all ages and both genders attending SQUH and receiving antifungal medications at the study period. Frequencies and percentages were reported for categorical variables, while the mean and standard deviation were used to summarize the data for continuous variables. RESULTS A total of 1353 antifungal drug prescriptions were prescribed for 244 patients. More than half of all antifungal drug prescriptions were prescribed by haematology, infectious disease and family medicine departments. The majority of patients to whom these drugs were prescribed were diagnosed to have infectious diseases followed by prophylactic use in leukaemias and immunocompromised conditions. Fluconazole was the most commonly prescribed antifungal drug (n=715, 52.8%) followed by nystatin and voriconazole (n=233; 17.2% and n=152; 11.2%, respectively). CONCLUSION This study will help in understanding antifungal prescription practices and help in directing future studies and also in developing local policies for appropriate use of antifungal drugs.

Abstract
Patients undergoing allogeneic haematopoietic stem cell transplantation (alloHSCT) are at risk of developing invasive fungal infections (IFIs). Even with introduction of oral triazole antifungal agents (fluconazole, itraconazole, posaconazole and voriconazole) IFI-associated morbidity and mortality rates and economic burden remain high. Despite their proven efficacy, it is currently unknown which is the most cost-effective antifungal prophylaxis (AFP) agent. To determine the costs and outcomes associated with AFP, a decision-analytic model was used to simulate treatment in a hypothetical cohort of 1000 patients undergoing alloHSCT from the perspective of the Spanish National Health System. Generic itraconazole was the least costly AFP (€162) relative to fluconazole (€500), posaconazole oral suspension (€8628) or voriconazole (€6850). Compared with posaconazole, voriconazole was associated with the lowest number of breakthrough IFIs (36 vs 60); thus, the model predicted fewer deaths from breakthrough IFI for voriconazole (24) than posaconazole (33), and the lowest predicted costs associated with other licensed antifungal treatment and IFI treatment in a cohort of 1000. Voriconazole resulted in cost savings of €4707 per patient compared with posaconazole. Itraconazole demonstrated a high probability of being cost-effective. As primary AFP in alloHSCT patients 180 days posttransplant, voriconazole was more likely to be cost-effective than posaconazole regarding cost per additional IFI and additional death avoided.

Abstract
Isavuconazole, the active moiety of the water-soluble prodrug isavuconazonium sulfate, is a triazole antifungal agent used for the treatment of invasive fungal infections. The objective of this analysis was to develop a population pharmacokinetic (PPK) model to identify covariates that affect isavuconazole pharmacokinetics and to determine the probability of target attainment (PTA) for invasive aspergillosis patients. Data from nine phase 1 studies and one phase 3 clinical trial (SECURE) were pooled to develop the PPK model (NONMEM, version 7.2). Stepwise covariate modeling was performed in Perl-speaks-NONMEM, version 3.7.6. The area under the curve (AUC) at steady state was calculated for 5,000 patients by using Monte Carlo simulations. The PTA using the estimated pharmacodynamic (PD) target value (total AUC/MIC ratio) estimated from in vivo PD studies of invasive aspergillosis over a range of MIC values was calculated using simulated patient AUC values. A two-compartment model with a Weibull absorption function and a first-order elimination process adequately described plasma isavuconazole concentrations. The mean estimate for isavuconazole clearance was 2.360 liters/h (percent coefficient of variation [%CV], 34%), and the mean AUC from 0 to 24 h (AUC0-24) was ∼100 mg·h/liter. Clearance was approximately 36% lower in Asians than in Caucasians. The PTA calculated over a range of MIC values by use of the nonneutropenic murine efficacy index corresponding to 90% survival indicated that adequate isavuconazole exposures were achieved in >90% of simulated patients to treat infections with MICs up to and including 1 mg/liter according to European Committee on Antimicrobial Susceptibility Testing methodology and in >90% of simulated patients for infections with MICs up to and including 0.5 mg/liter according to Clinical and Laboratory Standards Institute methodology. The highest MIC result for PTA was the same for Caucasian and Asian patients.

Abstract
OBJECTIVE In the phase III SECURE trial, isavuconazole was non-inferior to voriconazole for all-cause mortality for the primary treatment of invasive mold disease (IMD) caused by Aspergillus spp. and other filamentous fungi. This analysis assessed whether hospital resource utilization was different between patients treated with isavuconazole vs voriconazole in SECURE. METHODS The analysis population comprised adults with proven/probable/possible IMD enrolled in SECURE. The primary endpoint was hospital length of stay (LOS) in the overall trial population. Patients were also stratified by estimated glomerular filtration rate-modification of diet in renal disease category (< 60 mL/min/1.73 m(2) [moderate-to-severe impairment] and ≥60 mL/min/1.73 m(2) [mild or no impairment]), body mass index (BMI; <25, ≥25-<30, and ≥30 kg/m(2)), and age (≤45, >45-≤65, and >65 years). RESULTS Data from 516 patients (258 per arm) were evaluated. Overall, median LOS was not statistically significantly different between the isavuconazole (15.0 days) and voriconazole (16.0 days; p = 0.607) arms. Median LOS was statistically significantly shorter in patients with moderate-to-severe renal impairment treated with isavuconazole (9.0 days) vs voriconazole (19.0 days; hazard ratio [HR]: 3.44; 95% confidence interval [CI] = 1.51-7.83). Median LOS was shorter, but not significantly, in patients with a BMI ≥30 kg/m(2) (isavuconazole 13.5 days vs voriconazole 22 days; HR = 1.57; 95% CI = 0.70-3.52) or aged >65 years (isavuconazole 15.0 days vs voriconazole 20.0 days; HR = 1.37; 95% CI = 0.87-2.16). LIMITATIONS As the patient subgroups analyzed were small, sub-group findings should be interpreted with caution in light of the lack of statistical significance for each sub-group-by-treatment interaction. CONCLUSIONS Isavuconazole may reduce hospital LOS in certain subgroups of patients with IMD, especially those with moderate-to-severe renal impairment.
