Mucorales: A systematic review to inform the World Health Organization priority list of fungal pathogens. Med Mycol 2024; 62:myad130. [PMID: 38935901 PMCID: PMC11210621 DOI: 10.1093/mmy/myad130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Revised: 11/18/2023] [Accepted: 12/11/2023] [Indexed: 06/29/2024] Open
Abstract
The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal priority pathogens list (FPPL). This systematic review aimed to evaluate the epidemiology and impact of invasive fungal disease due to Mucorales. PubMed and Web of Science were searched to identify studies published between January 1, 2011 and February 23, 2021. Studies reporting on mortality, inpatient care, complications and sequelae, antifungal susceptibility, risk factors, preventability, annual incidence, global distribution, and emergence during the study time frames were selected. Overall, 24 studies were included. Mortality rates of up to 80% were reported. Antifungal susceptibility varied across agents and species, with the minimum inhibitory concentrations lowest for amphotericin B and posaconazole. Diabetes mellitus was a common risk factor, detected in 65%-85% of patients with mucormycosis, particularly in those with rhino-orbital disease (86.9%). Break-through infection was detected in 13.6%-100% on azole or echinocandin antifungal prophylaxis. The reported prevalence rates were variable, with some studies reporting stable rates in the USA of 0.094-0.117/10 000 discharges between 2011 and 2014, whereas others reported an increase in Iran from 16.8% to 24% between 2011 and 2015. Carefully designed global surveillance studies, linking laboratory and clinical data, are required to develop clinical breakpoints to guide antifungal therapy and determine accurate estimates of complications and sequelae, annual incidence, trends, and global distribution. These data will provide robust estimates of disease burden to refine interventions and better inform future FPPL.

Abstract
The first patients positive for SARS-CoV-2 were registered in December 2019. In March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a global pandemic, the beginning of a worldwide health crisis that revealed numerous medical challenges for healthcare systems and pandemic emergency strategies.Among these challenges, mucormycosis, a typically rare fungal infection, gained global attention. With an average global incidence of about 2 per 1 million people, mucormycosis is considered a very rare disease, an opportunistic infection mostly affecting the lungs or skin and soft tissues in immunocompromised patients. Poorly controlled diabetes mellitus is one of the leading risk factors for rhino-orbital mucormycosis. Countries with a high prevalence of diabetes and limited healthcare resources have higher mucormycosis rates, with India and Pakistan being among the nations with particularly high incidences.During the second wave of the COVID-19 pandemic in India, mucormycosis rates surged dramatically within a few weeks, with over 47,500 cases of COVID-19-associated mucormycosis (CAM) reported between May and August 2021. Mucormycosis is characterized by a high mortality rate of up to 90%, especially when the diagnosis is delayed, and treatment commences late. There were concerns about a potentially global threat.In this article, we explore the risk factors and mechanisms leading to this viral-fungal coinfection. We present global distribution patterns, clinical presentation, and challenges in the diagnosis and treatment of COVID-19-associated mucormycosis.

Economic impact of managing invasive mold disease with isavuconazole compared with liposomal amphotericin B followed by posaconazole in Spain. Expert Rev Anti Infect Ther 2024:1-8. [PMID: 38494912 DOI: 10.1080/14787210.2024.2327517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Accepted: 02/29/2024] [Indexed: 03/19/2024]
Abstract
BACKGROUND Invasive fungal infections (IFI) are associated with significant morbidity and mortality. The objective of this work was to compare the costs per adult patient, associated with intravenous isavuconazole (ISAV) followed by oral ISAV versus the regimen of liposomal amphotericin B followed by posaconazole (L-AMB→POSA) in the treatment of IFI. The comparison was conducted from the perspective of the Spanish National Health System (SNS). METHODS As indirect comparisons have demonstrated similar efficacy between the comparators, a cost-minimization approach was taken. Drug acquisition, administration, hospitalization, laboratory tests and adverse events costs were evaluated from SNS perspective. Deterministic and probabilistic sensitivity analyzes were performed. RESULTS Total costs per-patient were €24,715.54 with ISAV versus €29,753.53 with L-AMB→POSA, resulting in cost-savings per patient treated with ISAV of €5,037.99 (-16.9%). Treatment costs of IFI remained lower for ISAV than for L-AMB→POSA across all sensitivity analyses (-7,968.89€ to -326.59€), being treatment duration the most influential parameter. CONCLUSION According to the present model, the treatment of IFIs with ISAV would generate savings for the SNS compared to L-AMB→POSA. These savings are attributed to the shorter duration of IV treatment, reduced use of healthcare resources and lower costs associated with managing adverse effects when ISAV was employed.

Abstract
The European Confederation of Medical Mycology (ECMM), formed due to the surge in invasive fungal infections (IFI), initiated the Excellence Centers program in 2016 to guide stakeholders to leading medical mycology sites. This report focuses on the Cologne ECMM Excellence Center, recognized with Diamond status for active global involvement in 2017. The center offers free consultation via email and phone, responding within 24 h for life-threatening IFI, collecting data on origin, pathogens, infection details, and more. Over two years, 189 requests were received globally, predominantly from Germany (85%), mainly involving Aspergillus spp., Mucorales, and Candida spp. Fungal mixed infections occurred in 4% of cases. The center's service effectively addresses IFI challenges, advocating for a comprehensive study encompassing all ECMM Excellence Centers to enhance global mycological care. Proactive expansion of consultancy platforms is crucial, with future analyses needed to assess expert advice's impact on patient outcomes.

Abstract
Background Mucormycosis is a potentially lethal mycosis. We reviewed peer-reviewed publications on mucormycosis to assess therapeutic outcomes. Methods A systematic literature search using the Ovid MEDLINE and EMBASE databases identified manuscripts describing human mucormycosis diagnosed according to European Organization for Research and Treatment of Cancer and the Mycoses Study Group criteria with therapeutic outcomes published from 2000 to 2022. Results In 126 articles, 10 335 patients were described, most from Asia (n = 6632, 66%). Diabetes was the most frequent underlying disease (n = 6188, 60%); 222 (2.1%) patients had no underlying diseases. The dominant clinical form was rhino-orbitocerebral (n = 7159, 69.3%), followed by pulmonary (n = 1062, 10.3%). Of 5364 patients with outcome data, amphotericin B monotherapy (n = 3749, mortality 31.5%) was most frequent, followed by amphotericin B + azole (n = 843, mortality 6.6%; P < .0001), amphotericin B followed by azole (n = 357, mortality 13.7%; P < .0001), posaconazole only (n = 250, mortality 17.2%; P < .0001), and isavuconazole only (n = 65, mortality 24.6%; P = .24). Duration and dose of antifungals varied widely. Documented outcomes from surgical resections in 149 patients found that 47 of 125 died (37.6%), compared with 16 of 24 (66.7%) patients who did not undergo surgery (P = .008). Conclusions Mucormycosis is more frequently reported in Asia than in Europe and is often linked to diabetes. Antifungal therapy, usually with surgery, is frequently effective for mucormycosis.

Lack of surgical resection is associated with increased early mortality in hematological patients complicated with rhino-orbital-cerebral mucormycosis. Ann Hematol 2023; 102:2933-2942.

Abstract
Rhino-orbital-cerebral mucormycosis (ROCM), which is an acute fatal infectious disease with a high mortality rate, is increasingly being diagnosed in patients with hematological diseases worldwide. We aimed to investigate the clinical characteristics, treatment, and prognosis of hematological diseases complicated by ROCM. Our sample comprised a total of 60 ROCM patients with hematological diseases. The most common primary disease was acute lymphoblastic leukemia (ALL) (n=27, 45.0%), while 36 patients (60.0%) were diagnosed with a clear type of pathogen, all belonging to the Mucorales, most commonly Rhizopus (41.7%). Of the 32 patients (53.3%) who died, 19 (59.3%) died of mucormycosis, and 84.2% (n=16) of those died within 1 month. Forty-eight cases (80.0%) received antifungal treatment combined with surgical therapy, 12 of whom (25.0%) died of mucormycosis, amounting to a mortality rate that was significantly lower than in patients who received antifungal therapy alone (n=7, 58.3%) (P=0.012). The median neutrophil value of patients who underwent surgery was 0.58 (0.11-2.80) 103/μL, the median platelet value was 58.00 (17.00-93.00) 103/μL, and no surgery-related deaths were reported. Multivariate analysis showed that patient's advanced age (P=0.012, OR=1.035 (1.008-1.064)) and lack of surgical treatment (P=0.030, OR=4.971 (1.173-21.074)) were independent prognostic factors.In this study, hematological diseases associated with ROCM have a high mortality rate. Lack of surgical treatment is an independent prognostic factor for death from mucormycosis. Surgery may therefore be considered in patients with hematological disease even if their neutrophil and platelet values are lower than normal.

Abstract
The incidence rate of invasive mucormycosis (IM) in patients with hematological malignancies (HMs) is increasing year by year, ranging from 0.07% to 4.29%, and the mortality rate is mostly higher than 50%. With the ongoing pandemic of COVID-19, COVID-19-associated mucormycosis (CAM) also became a global health threat. Patients with high risk factors such as active HMs, relapsed/refractory leukemia, prolonged neutropenia may still develop breakthrough mucormycosis (BT-MCR) even under the prophylaxis of Mucorales-active antifungals, and such patients often have higher mortality. Rhizopus spp. is the most common genus associated with IM, followed by Mucor spp. and Lichtheimia spp. Pulmonary mucormycosis (PM) is the most common form of IM in patients with HMs, followed by rhino-orbital-cerebral mucormycosis (ROCM) and disseminated mucormycosis. The prognosis of IM patients with neutrophil recovery, localized IM and receiving early combined medical-surgical therapy is usually better. As for management of the disease, risk factors should be eliminated firstly. Liposome amphotericin B (L-AmB) combined with surgery is the initial treatment scheme of IM. Those who are intolerant to L-AmB can choose intravenous formulations or tablets of isavuconazole or posaconazole. Patients who are refractory to monotherapy can turn to combined antifungals therapy.

Abstract
Invasive mold diseases are devastating systemic infections which demand meticulous care in selection, dosing, and therapy monitoring of antifungal drugs. Various circumstances regarding PK/PD properties of the applied drug, resistance/tolerance of the causative pathogen or host intolerability can lead to failure of the initial antifungal therapy. This necessitates treatment adaption in the sense of switching antifungal drug class or potentially adding another drug for a combination therapy approach. In the current state of drastically limited options of antifungal drug classes adaption of therapy remains challenging. Current guidelines provide restricted recommendations only and emphasize individual approaches. However, novel antifungals, incorporating innovative mechanisms of action, show promising results in late stage clinical development. These will expand options for salvage therapy in the future potentially as monotherapy or in combination with conventional or other novel antifungals. We outline current recommendations for salvage therapy including PK/PD considerations as well as elucidate possible future treatment options for invasive aspergillosis and mucormycosis.

Abstract
The surge of COVID-19 associated Mucormycosis (CAM) in India during the second wave of COVID-19 led to lack of availability of amphotericin B(AmB). We retrospectively evaluated the outcome in 28 consecutive patients with CAM who received posaconazole (PCZ) or isavuconazole (ISVCZ) as sole or predominant therapy, based on factors like availability, affordability, site of infection or lack of treatment response. Therapeutic drug monitoring was used for PCZ in all cases & for ISVCZ in some cases. Higher trough levels were aimed to ensure therapeutic effect. Overall, 16 patients were cured, 5 patients improved, 6 patients died, of which 2 deaths were attributable to mucormycosis and 1 patient was lost to follow-up. The outcomes and survival were comparable to those reported in the literature. Although wider applicability of these results cannot be assumed, it leads to a speculation that treatment of mucormycosis with PCZ or ISVCZ, without AmB, is possible.

Abstract
BACKGROUND Along with COVID-19 pandemic, India has faced an outbreak of COVID-19-associated mucormycosis (CAM). Due to restricted availability of amphotericin B during this outbreak, clinicians were forced to use posaconazole or isavuconazole preparations as first-line or alternate therapy in many patients. We planned an early monitoring of posaconazole trough level while using delayed release (DR) tablet as first-line or alternate therapy. OBJECTIVES Primary objective of the study was to determine percentage of patients achieving arbitrarily decided therapeutic posaconazole levels (≥1.2 μg/ml) after using standard dosages of posaconazole. Secondary objective was to identify potential factors associated with sub-therapeutic posaconazole levels. METHODS We performed retrospective chart review of the hospitalised patients, who received posaconazole DR tablet as first-line or alternate therapy to treat CAM during outbreak period (March 1 to May 31, 2021). High-performance liquid chromatographic (HPLC) method was used to measure trough level of posaconazole. RESULTS Posaconazole serum levels of 29 patients were analysed, who received posaconazole DR tablet. Majority (n = 23) were male with the median (range) age 53 (24-86) years. The mean (SD) posaconazole level was 1.66 (0.76) μg/ml. Sub-therapeutic posaconazole trough level was observed in 7 (24.1%) patients. Relatively younger patients were associated with lower posaconazole level (p = .046). Except two patients, all the patients tolerated posaconazole well. CONCLUSIONS The study supports the posaconazole trough level measurement on day 4 while using posaconazole DR tablet as first-line or alternate therapy to treat mucormycosis during limited supply of amphotericin B.

Abstract
Invasive fungal disease (IFD) due to moulds other than Aspergillus is a significant cause of mortality in patients with malignancies or post haemopoietic stem cell transplantation. The current guidelines focus on the diagnosis and management of the common non-Aspergillus moulds (NAM), such as Mucorales, Scedosporium species (spp.), Lomentospora prolificans and Fusarium spp. Rare but emerging NAM including Paecilomyces variotii, Purpureocillium lilacinum and Scopulariopsis spp. are also reviewed. Culture and histological examination of tissue biopsy specimens remain the mainstay of diagnosis, but molecular methods are increasingly being used. As NAM frequently disseminate, blood cultures and skin examination with biopsy of any suspicious lesions are critically important. Treatment requires a multidisciplinary approach with surgical debridement as a central component. Other management strategies include control of the underlying disease/predisposing factors, augmentation of the host response and the reduction of immunosuppression. Carefully selected antifungal therapy, guided by susceptibility testing, is critical to cure. We also outline novel antifungal agents still in clinical trial which offer substantial potential for improved outcomes in the future. Paediatric recommendations follow those of adults. Ongoing epidemiological research, improvement in diagnostics and the development of new antifungal agents will continue to improve the poor outcomes that have been traditionally associated with IFD due to NAM.

Abstract
BACKGROUND Mucormycosis (zygomycosis) is an invasive fungal infection that carries a high risk of morbidity and mortality. Uncontrolled diabetes mellitus and other immunocompromising conditions are risk factors for mucormycosis development. We here describe the differences in characteristics and outcomes of mucormycosis among solid organ transplant, hematological malignancy, and diabetes mellitus groups at our institution. METHODS We conducted a retrospective chart review over the period of 2009-2020, with identifying patients using the International Classification of Diseases, Ninth and Tenth Revisions. Clinical, laboratory, and outcome data were collected. RESULTS There were 28 patients identified: 7 solid organ transplant, 3 hematological malignancy, and 18 diabetes mellitus patients were included in the study. Three solid organ transplant patients experienced an episode of rejection, and another 3 had cytomegalovirus infection prior to presenting with mucormycosis. Four of seven solid organ transplant patients had a history of diabetes mellitus, but the median hemoglobin A1C was lower than in the diabetes mellitus group (6.3 vs 11.5; P = .006). The mortality rate difference between solid organ transplant and diabetes mellitus was not statistically significant: 2/7 (28.57%) vs 5/18 (27.78%); P = .66. Patients with bilateral disease (pulmonary or sinus) had significantly higher mortality (80% vs 13%, P = .008). There was no difference in mortality outcomes among the different types of antifungal therapies administered. CONCLUSION A multispecialty approach is imperative in mucormycosis therapy. While the underlying risk factors were different, the outcomes were comparable for the solid organ transplant and diabetes mellitus groups. Future larger and longitudinal studies are recommended.

Abstract
The advent of bone marrow transplant has opened doors to a different approach and
offered a new treatment modality for various hematopoietic stem-cell-related
disorders. Since the first bone marrow transplant in 1957, there has been
significant progress in managing patients who undergo bone marrow transplants.
Plasma-cell disorders, lymphoproliferative disorders, and myelodysplastic
syndrome are the most common indications for hematopoietic stem-cell transplant.
Despite the advances, invasive fungal infections remain a significant cause of
morbidity and mortality in this high-risk population. The overall incidence of
invasive fungal infection in patients with hematopoietic stem-cell transplant is
around 4%, but the mortality in patients with allogeneic stem-cell transplant is
as high as 13% in one study. Type of stem-cell transplant, conditioning regimen,
and development of graft-versus-host disease are some of the
risk factors that impact the risk and outcomes in patients with invasive fungal
infections. Aspergillus and candida remain the two most common organisms causing
invasive fungal infections. Molecular diagnostic methods have replaced some
traditional methods due to their simplicity of use and rapid turnaround time.
Primary prophylaxis has undoubtedly shown to improve outcomes even though
breakthrough infection rates remain high. The directed treatment has seen a
significant shift from amphotericin B to itraconazole, voriconazole, and
echinocandins, which have shown better efficacy and fewer adverse effects. In
this comprehensive review, we aim to detail epidemiology, risk factors,
diagnosis, and management, including prophylaxis, empiric and directed
management of invasive fungal infections in patients with hematopoietic
stem-cell transplant.

In vitro activity of posaconazole and comparators versus opportunistic filamentous fungal pathogens globally collected during 8 years. Diagn Microbiol Infect Dis 2021; 101:115473.

Abstract
The epidemiology of invasive filamentous fungal diseases requires monitoring due to changes in susceptibility patterns of new and established antifungal agents that may affect clinical practices. We evaluated the activity of posaconazole against 2,157 invasive moulds collected worldwide from 2010-2017. The isolates included 1,775 Aspergillus spp. and 382 non-Aspergillus moulds, including 81 Fusarium spp., 62 Mucorales group, and 57 Scedosporium spp. Isolates were tested using the CLSI reference broth microdilution method. Posaconazole showed similar activity to itraconazole and voriconazole against A. fumigatus. Applying published ECV, 98.0% of the A. fumigatus and 97.7% to 100.0% of other common Aspergillus species were wildtype to posaconazole. Categorical agreement between posaconazole and the other azoles tested against A. fumigatus was 98.7%. Notably, most of the Aspergillus spp. isolates recovered from this large collection were wildtype to echinocandins and all azoles. Posaconazole non-wildtype rates of A. fumigatus varied across the different geographic regions, with 2.1% in Europe, 2.2% in North America, 1.8% in Latin America, and 0.7% in the Asia-Pacific region. The frequency of azole non-wildtype A. fumigatus isolates from Europe increased steadily from 2010-2017 for all 3 triazoles (0.0%-5.0%). The azole non-wildtype A. fumigatus rates from the other geographic areas were stable over time. Fusarium and/or Scedosporium spp. isolates were highly resistant to azoles and echinocandins. Posaconazole and amphotericin B were the most active agents against the Mucorales. Posaconazole was very active against most species of Aspergillus and was comparable to itraconazole and voriconazole against the less common moulds. Posaconazole should provide a useful addition to the anti-mould grouping of antifungal agents.

Abstract
OBJECTIVES Pulmonary mucormycosis (PM) is increasingly being reported in immunocompromised patients and has a high mortality. Our aim was to assess the mortality of PM and its trend over time. We also evaluated the role of combined medical-surgical therapy in PM. METHODS We performed a systematic review of Pubmed, Embase, and Cochrane central databases. Studies were eligible if they described at least five confirmed cases of PM and reported mortality. We also assessed the effect of combined medical-surgical therapy versus medical treatment alone on PM mortality. We used a random-effects model to estimate the pooled mortality of PM and compared it across three time periods. The factors influencing mortality were assessed using meta-regression. We evaluated the risk difference (RD) of death in the following: subjects undergoing combined medical-surgical therapy versus medical therapy alone, subjects with isolated PM versus disseminated disease, and PM in diabetes mellitus (DM) versus non-DM as a risk factor. RESULTS We included 79 studies (1544 subjects). The pooled mortality of PM was 57.1% (95% confidence interval [CI] 51.7-62.6%). Mortality improved significantly over time (72.1% versus 58.3% versus 49.8% for studies before 2000, 2000-2009, and 2010-2020, respectively, p 0.00001). This improved survival was confirmed in meta-regression after adjusting for the study design, the country's income level, and the sample size. Combined medical-surgical therapy was associated with a significantly lower RD (95%CI) of death: -0.32 (-0.49 to -0.16). The disseminated disease had a higher risk of death than isolated PM, but DM was not associated with a higher risk of death than other risk factors. CONCLUSIONS While PM is still associated with high mortality, we noted improved survival over time. Combined medical-surgical therapy improved survival compared to medical treatment alone.

Host-Pathogen Molecular Factors Contribute to the Pathogenesis of Rhizopus spp. in Diabetes Mellitus. CURRENT TROPICAL MEDICINE REPORTS 2021; 8:6-17.

Abstract
Purpose of Review Infectious diseases represent up to 12% of all deaths in people with diabetes mellitus (DM). The development and progression of DM generate a chronic inflammatory state with unique characteristics that have been exploited by some pathogens; one of them is Rhizopus spp., a fungus considered the causative agent of mucormycosis. This disease has a poor prognosis with high mortality rates, and the apparition of resistant isolates each year has become a worrying concern. DM is an actual and continuing health problem, and for that reason, it is of foremost importance to study the pathogenesis of mucormycosis to generate new prevention and treatment strategies. Recent Findings The worldwide incidence of mucormycosis has increased in recent years. The pathogenic mechanisms and factors identified in Rhizopus spp. are the cell wall, spore germination, proteins, and enzymes related to iron sequestration, CotH fungal protein, positive regulation of the GRP78 cell receptor, and immune evasion due to survival within phagocytes, among others. The physiopathology of DM offers favorable conditions for the successful replication of Rhizopus spp. Summary The main reason for increase of incidence of mucormycosis caused by Rhizopus spp. has been associated with the rise of worldwide prevalence of DM. Knowing the fungal pathogenic mechanisms as well as the relationships between Rhizopus with the microenvironment found in the human body will undoubtedly help generate better antifungals to enhance treatment outcomes. Nowadays, some strategies to combat the fungus are based on the knowledge of its proteins, cellular interactions, and iron metabolism.

Abstract
Posaconazole is typically used for preventing invasive yeast and mold infections such as invasive aspergillosis in high-risk immunocompromised patients. The oral suspension was the first released formulation and many pharmacokinetic and pharmacodynamic studies of this formulation have been published. Erratic absorption profiles associated with this formulation were widely reported. Posaconazole exposure was found to be significantly influenced by food and many gastrointestinal conditions, including pH and motility. As a result, low posaconazole plasma concentrations were obtained in large groups of patients. These issues of erratic absorption urged the development of the subsequently marketed delayed-release tablet, which proved to be associated with higher and more stable exposure profiles. Shortly thereafter, an intravenous formulation was released for patients who are not able to take oral formulations. Both new formulations require a loading dose on day 1 to achieve high posaconazole concentrations more quickly, which was not possible with the oral suspension. So far, there appears to be no evidence of increased toxicity correlated to the higher posaconazole exposure achieved with the regimen for these formulations. The higher systemic availability of posaconazole for the delayed-release tablet and intravenous formulation have resulted in these two formulations being preferable for both prophylaxis and treatment of invasive fungal disease. This review aimed to integrate the current knowledge on posaconazole pharmacokinetics, pharmacodynamics, major toxicity, existing resistance, clinical experience in special populations, and new therapeutic strategies in order to get a clear understanding of the clinical use of this drug.

Abstract
BACKGROUND Regional differences in the underlying causes, manifestations and treatment of mucormycosis have been noted in studies covering Europe, Asia and South America. OBJECTIVES To review cases of mucormycosis across the Middle East and North Africa (MENA) region in order to identify epidemiological, treatment and outcome trends in this region. PATIENTS/METHODS Cases of proven or probable invasive mucormycosis from the region were identified from the FungiScope® database and the medical literature. For each case, information on underlying condition, site of infection, pathogenic species, therapeutic intervention, type of antifungal therapy and outcome were analysed. RESULTS We identified 310 cases of mucormycosis in the MENA region. The number of reported cases increased by decade from 23 before 1990 to 127 in the 2010s. In this region, the most common underlying conditions associated with mucormycosis were diabetes mellitus (49.7%) and conditions associated with immunosuppression (46.5%). The majority of patients received treatment with antifungals (93.5%), with a large proportion treated with both antifungals and surgery (70.6%). Overall mortality rates decreased from 47.8% before 1990 to 32.3% in the 2010s. CONCLUSIONS The number of reported cases of mucormycosis in the MENA region has risen over the past few decades, in line with increases in the number of patients with underlying conditions associated with this infection. Although the majority of patients received treatment with antifungal therapies and/or surgery, the associated mortality rate remains high and there is a clear need for more effective prevention and treatment strategies in the MENA region.

Abstract
OBJECTIVES Emerging invasive fungal infections (IFI) have become a notable challenge. Apart from the more frequently described fusariosis, lomentosporiosis, mucormycosis, scedosporiosis, and certain dematiaceae or yeasts, little is known about extremely rare IFI. METHODS Extremely rare IFI collected in the FungiScopeⓇ registry were grouped as Dematiaceae, Hypocreales, Saccharomycetales, Eurotiales, Dermatomycetes, Agaricales, and Mucorales. RESULTS Between 2003 and June 2019, 186 extremely rare IFI were documented in FungiScopeⓇ. Dematiaceae (35.5%), Hypocreales (23.1%), Mucorales (11.8%), and Saccharomycetales (11.3%) caused most IFI. Most patients had an underlying malignancy (38.7%) with acute leukemia accounting for 50% of cancers. Dissemination was observed in 26.9% of the patients. Complete or partial clinical response rate was 68.3%, being highest in Eurotiales (82.4%) and in Agaricales (80.0%). Overall mortality rate was 29.3%, ranging from 11.8% in Eurotiales to 50.0% in Mucorales. CONCLUSIONS Physicians are confronted with a complex variety of fungal pathogens, for which treatment recommendations are lacking and successful outcome might be incidental. Through an international consortium of physicians and scientists, these cases of extremely rare IFI can be collected to further investigate their epidemiology and eventually identify effective treatment regimens.

Abstract
INTRODUCTION Mucormycoses represent a rare but very aggressive class of mold infections occurring in patients with hematological malignancies (HMs). In the past, patients at high risk of invasive mucomycosis (IM) were those affected by acute myeloid leukemia but over the last ten years the prophylaxis with a very effective mold-active drug, such as posaconazole, has completely modified the epidemiology. In fact, IM is now observed more frequently in patients with lymphoproliferative disorders who do not receive antifungal prophylaxis. AREAS COVERED The attention was focused on the epidemiology, diagnosis, prophylaxis and treatment of IM in HMs. Authors excluded pediatric patients considering the different epidemiology and differences in treatment given the limitation of the use of azoles in the pediatric field. A systematic literature review was performed using PubMed database listings between February 2014 and February 2020 using the following MeSH terms: leukemia, hematological malignancies, stem cell transplantation, mucormycosis, molds, prophilaxis, treatment. EXPERT OPINION The epidemiology of mucormycosis in HMs is changing in the last years. The availability of drugs more effective than in the past against this infection has reduced the mortality; however, a timely diagnosis remains a relevant problem potentially influencing the outcome of hematologic patients with IM.

Abstract
Purpose of review This review highlights research from the past five years on combat trauma-related invasive fungal wound infections (IFIs) with a focus on risk stratification to aid patient management, microbiology, and diagnostics. Recent Findings A revised classification scheme stratifies wounds into three risk groups: IFI, High Suspicion of IFI, and Low Suspicion of IFI. This stratification is based on persistence of wound necrosis and laboratory fungal evidence, presence of signs/symptoms of deep soft-tissue infections, and the need for antifungals. Use of this classification could allow for prioritization of antifungal therapy. Further, IFIs delay wound healing, particularly when caused by fungi of the order Mucorales. Lastly, molecular sequencing offers promising and complimentary results to the gold standard histopathology. Summary Optimal management of combat-related IFIs depends on early tissue-based diagnosis with aggressive surgical debridement and concomitant dual antifungal therapy. Further research on clinical decision support tools and rapid diagnostics are needed.

Abstract
Mucormycosis are life-threatening fungal infections especially affecting immunocompromised or diabetic patients. Despite treatment, mortality remains high (from 32 to 70% according to organ involvement). This review provides an update on mucormycosis management. The latest recommendations strongly recommend as first-line therapy the use of liposomal amphotericin B (≥5mg/kg) combined with surgery whenever possible. Isavuconazole and intravenous or delayed-release tablet forms of posaconazole have remained second-line. Many molecules are currently in development to fight against invasive fungal diseases but few have demonstrated efficacy against Mucorales. Despite in vitro efficacy, combinations of treatment have failed to demonstrate superiority versus monotherapy. Adjuvant therapies are particularly complex to evaluate without prospective randomized controlled studies, which are complex to perform due to low incidence rate and high mortality of mucormycosis. Perspectives are nonetheless encouraging. New approaches assessing relationships between host, fungi, and antifungal drugs, and new routes of administration such as aerosols could improve mucormycosis treatment.

Abstract
PURPOSE OF REVIEW This article aimed to review animal models of antifungals and identifies human literature to assess if the extrapolation of results is reliable. RECENT FINDINGS Animal studies have helped identify AUC/MIC targets for new drugs and formulations such as isavuconazole and delayed release posaconazole that have translated to successful outcomes in humans. Models have also been influential in the identification of possible combination therapies for the treatment of aspergillosis, such as voriconazole and echinocandins. However, challenges are endured with animal models when it comes to replicating the pharmacokinetics of humans which has been exemplified with the newest itraconazole formulation. Additionally, animal models have displayed a survival benefit with the use of iron chelators and amphotericin for mucormycosis which was not demonstrated in humans. SUMMARY Animal models have been a staple in the development and optimization of antifungal agents. They afford the ability to investigate uncommon diseases, such as invasive fungal infections, that would otherwise take years and many resources to complete. Although there are many benefits of animal models there are also shortcomings. This is why the reliability of extrapolating data from animal models to humans is often scrutinized.

High-dose posaconazole for azole-resistant aspergillosis and other difficult-to-treat mould infections. Mycoses 2019; 63:122-130.

Abstract
Background Oral follow‐up therapy is problematic in moulds with reduced azole‐susceptibility, such as azole‐resistant Aspergillus fumigatus infection. Currently, only intravenous liposomal amphotericin B (L‐AmB) is advocated by guidelines for the treatment of azole‐resistant aspergillosis infections. Preclinical research indicates that high‐dose posaconazole (HD‐POS) might be a feasible option provided that high drug exposure (ie POS serum through levels >3 mg/L) can be achieved and is safe. Objectives To describe our experience with the use of oral HD‐POS as treatment strategies for patients infected with pathogens with a POS MIC close to the clinical breakpoint. Patients/Methods We review evidence supporting the use of HD‐POS and describe our experience on safety and efficacy in 16 patients. In addition, we describe the adverse events (AE) observed in 25 patients with POS concentrations at the higher end of the population distribution during treatment with the licensed dose. Results Sixteen patients were treated intentionally with HD‐POS for voriconazole‐resistant invasive aspergillosis (7/16), mucormycosis (4/16), salvage therapy for IA (4/16) and IA at a sanctuary site (spondylodiscitis) in 1. Grade 3‐4 AEs were observed in 6, and all of them were considered at least possibly related. Grade 3‐4 AEs were observed in 5 of the 25 patients with spontaneous high POS serum through levels considered at least possibly related using Naranjo scale. Conclusions High‐dose posaconazole is a treatment option if strict monitoring for both exposure and for AE is possible.
