Abstract: International audience; Objectives: To determine the epidemiological cut-off values (ECVs) of ten antifungal agents in a wide range of yeasts and Aspergillus spp. using gradient concentration strips.Methods: The minimum inhibitory concentrations for amphotericin B, anidulafungin, caspofungin, micafungin, flucytosine, fluconazole, itraconazole, isavuconazole, posaconazole, and voriconazole, determined with gradient concentration strips at 35 French microbiology laboratories between 2002 and 2020, were retrospectively collected. Then, the ECVs were calculated using the iterative method and a cut-off value of 97.5%.Results: Minimum inhibitory concentrations were available for 17 653 clinical isolates. In total, 48 ECVs (including 32 new ECVs) were determined: 29 ECVs for frequent yeast species (e.g. Candida albicans and itraconazole/flucytosine, and Candida glabrata species complex [SC] and flucytosine) and rare yeast species (e.g. Candida dubliniensis, Candida inconspicua, Saccharomyces cerevisiae, and Cryptococcus neoformans) and 19 ECVs for Aspergillusflavus SC, Aspergillusfumigatus SC, Aspergillusnidulans SC, Aspergillusniger SC, and Aspergillusterreus SC.Conclusions: These ECVs can be added to the already available gradient concentration strip-specific ECVs to facilitate minimum inhibitory concentration interpretation and streamline the identification of nonwild type isolates.

Abstract: International audience; Cryptococcosis is the third most common cause of invasive fungal infection in solid organ transplant recipients and cryptococcal meningitis (CM) its main clinical presentation. CM outcomes, as well as its clinical features and radiological characteristics, have not yet been considered on a large scale in the context of kidney transplantation (KT). We performed a nationwide retrospective study of adult patients diagnosed with cryptococcosis after KT between 2002 and 2020 across 30 clinical centers in France. We sought to describe overall and graft survival based on whether KT patients with cryptococcosis developed CM or not. Clinical indicators of CNS involvement and brain radiological characteristics were assessed. Eighty-eight cases of cryptococcosis were diagnosed during the study period, with 61 (69.3%) cases of CM. Mortality was high (32.8%) at 12 months (M12) but not significantly different whether or not patients presented with CM. Baseline hyponatremia and at least one neurological symptom were independently associated with CM (p < 0.001). Positive serum cryptococcal antigen at diagnosis was also significantly associated with CM (p < 0.001). On magnetic resonance imaging (MRI), three patterns of brain injury were identified: parenchymal, meningeal, and vascular lesions. Although CM does not affect graft function directly, it entails a grim prognosis.

Abstract: International audience; This report is based on proceedings from the Exposure Assessment Tools for Hypersensitivity Pneumonitis (HP) Workshop, sponsored by the American Thoracic Society, that took place on May 18, 2019, in Dallas, Texas. The workshop was initiated by members from the Environmental, Occupational, and Population Health and Clinical Problems Assemblies of the American Thoracic Society. Participants included international experts from pulmonary medicine, occupational medicine, radiology, pathology, and exposure science. The meeting objectives were to 1) define currently available tools for exposure assessment in evaluation of HP, 2) describe the evidence base supporting the role for these exposure assessment tools in HP evaluation, 3) identify limitations and barriers to each tool's implementation in clinical practice, 4) determine which exposure assessment tools demonstrate the best performance characteristics and applicability, and 5) identify research needs for improving exposure assessment tools for HP. Specific discussion topics included history-taking and exposure questionnaires, antigen avoidance, environmental assessment, specific inhalational challenge, serum-specific IgG testing, skin testing, lymphocyte proliferation testing, and a multidisciplinary team approach. Priorities for research in this area were identified.

Abstract: Bird fancier's lung (BFL) is the most prevalent form of hypersensitivity pneumonitis (HP) worldwide. The current techniques used for the serological diagnosis of BFL all use crude extracts from feathers, droppings, and blooms as test antigens, which is associated with a lack of standardization and variability of the results. An antigenic protein, immunoglobulin lambda-like polypeptide-1 (IgLL1), isolated from pigeon droppings, was recently identified to be associated with BFL. We used genetic engineering to produce IgLL1 as a recombinant antigen.We aimed to prospectively validate the use of an automated ELISA based on recombinant IgLL1 protein (r-IgLL1) as the test antigen for the serological diagnosis of BFL.Immunoprecipitation (IP) techniques (immunodiffusion (ID), immunoelectrophoresis (IEP)) and ELISA using r-IgLL1 were performed concomitantly over 10 months on 634 sera from patients with a BFL serodiagnosis request. Questionnaires were sent to obtain details on the avian exposure, clinical data, and final diagnosis. Concordance, sensitivity (Se), and specificity (Sp) of the two techniques were compared.In total, 72 completed questionnaires were returned with 18 cases of BFL diagnosed and 54 of non-BFL. The concordance between the ELISA and ID+IEP precipitation techniques was 71%. The combination of immunoprecipitation techniques showed a Se of 78% and a Sp of 67%. The ELISA using r-IgLL1 showed a Se of 89% and a Sp of 91%. The automated r-IgLL1 ELISA test is sufficiently efficient to be used alone for the diagnosis of patients exposed solely to Columbidae. In cases of other avian exposure, the Se and Sp of the r-IgLL1 ELISA used for screening combined with the immunodiffusion test for confirmation were 89% and 93%, respectively.The automated ELISA using r-IgLL1 is a promising tool for BFL serodiagnosis. Replacing immunodiffusion by the automated ELISA using r-IgLL1 as a screening technique will be the basis of our future strategy for BFL serodiagnosis.

Abstract: Japanese encephalitis (JE) is a rare but severe disease. It is a potential threat for people traveling to endemic areas. The risk of developing JE is low (1%), but the associated case fatality is high (30%). There is no specific treatment for JE, but a vaccine is available. We performed an observational survey to assess practices of French health professionals regarding JE vaccination.Standardized questionnaires were sent by email to a sample of French health professionals practicing in vaccination centers. Participation was on a voluntary and anonymous basis. The questionnaires requested socio-demographic details, and included multiple choice questions.The response rate was 38.5%. Most participating health professionals had been working for more than three years in a vaccination center and declared not to be reluctant to perform JE vaccination. Reluctance was mostly based on the vaccine cost and on the difficulty to properly assess the risk for patients. The rapid protocol was largely preferred except in the overseas regions (P0.05, Fisher's exact test). Traveling to South Asia and backpacking were considered at-risk conditions. Participants proposed the vaccination all year round. Most participants would not have proposed the JE vaccination for the concrete case outlined in the questionnaire.French health professionals are globally favorable to JE vaccination. However, assessing the risk of exposure is difficult in routine practice.

Abstract: Background Early diagnosis and prompt initiation of specific antifungal treatment are essential for improving the prognosis of mucormycosis. We aimed to assess the performance of serum Mucorales quantitative polymerase chain reaction (qPCR) for the early diagnosis and follow-up of mucormycosis. Methods We prospectively enrolled 232 patients with suspicion of invasive mold disease, evaluated using standard imaging and mycological procedures. Thirteen additional patients with proven or probable mucormycosis were included to analyze DNA load kinetics. Serum samples were collected twice-a-week for Mucorales qPCR tests targeting the Mucorales genera Lichtheimia, Rhizomucor, and Mucor/Rhizopus. Results The sensitivity was 85.2%, specificity 89.8%, and positive and negative likelihood ratios 8.3 and 0.17, respectively in this prospective study. The first Mucorales qPCR-positive serum was observed a median of 4 days (interquartile range [IQR], 0–9) before sampling of the first mycological or histological positive specimen and a median of one day (IQR, −2 to 6) before the first imaging was performed. Negativity of Mucorales qPCR within seven days after liposomal-amphotericin B initiation was associated with an 85% lower 30-day mortality rate (adjusted hazard ratio = 0·15, 95% confidence interval [.03–.73], P = .02). Conclusions Our study argues for the inclusion of qPCR for the detection of circulating Mucorales DNA for mucormycosis diagnosis and follow-up after treatment initiation. Positive results should be added to the criteria for the consensual definitions from the European Organization for the Research and Treatment of Cancer/Mycoses Study Group Education and Research Consortium (EORTC/MSGERC), as already done for Aspergillus PCR.

Abstract: Objectives: Coronavirus disease 2019 (COVID-19) -associated pulmonary aspergillosis (CAPA) has emerged as a complication in critically ill COVID-19 patients. The objectives of this multinational study were to determine the prevalence of CAPA in patients with COVID-19 in intensive care units (ICU) and to investigate risk factors for CAPA as well as outcome. Methods: The European Confederation of Medical Mycology (ECMM) conducted a multinational study including 20 centres from nine countries to assess epidemiology, risk factors and outcome of CAPA. CAPA was defined according to the 2020 ECMM/ISHAM consensus definitions. Results: A total of 592 patients were included in this study, including 11 (1.9%) patients with histologically proven CAPA, 80 (13.5%) with probable CAPA, 18 (3%) with possible CAPA and 483 (81.6%) without CAPA. CAPA was diagnosed a median of 8 days (range 0–31 days) after ICU admission predominantly in older patients (adjusted hazard ratio (aHR) 1.04 per year; 95% CI 1.02–1.06) with any form of invasive respiratory support (HR 3.4; 95% CI 1.84–6.25) and receiving tocilizumab (HR 2.45; 95% CI 1.41–4.25). Median prevalence of CAPA per centre was 10.7% (range 1.7%–26.8%). CAPA was associated with significantly lower 90-day ICU survival rate (29% in patients with CAPA versus 57% in patients without CAPA; Mantel–Byar p < 0.001) and remained an independent negative prognostic variable after adjusting for other predictors of survival (HR 2.14; 95% CI 1.59–2.87, p ≤ 0.001). Conclusion: Prevalence of CAPA varied between centres. CAPA was significantly more prevalent among older patients, patients receiving invasive ventilation and patients receiving tocilizumab, and was an independent strong predictor of ICU mortality.

Abstract: International audience; In the non-AIDS group, several underlying conditions and immune defects could lead to different PCP presentations. This study compared PCP presentation and outcome according to the underlying disease. A secondary analysis of a previously published prospective observational study including 544 PCP patients was done. Only non-AIDS patients were included. Underlying disease was defined as chronic lymphocytic leukemia (CLL), organ transplantation, solid cancer, allogeneic hematopoietic stem cell transplant (AHSCT), other hematological diseases, and immunosuppressive treatment. Clinical characteristics and outcomes were compared between groups. Multiple correspondent analyses compared clinical characteristics at diagnosis. Day 30 mortality was analyzed. Three hundred and twenty-one patients were included in the study. The underlying diseases were hematological malignancy (n = 75), AHSCT (n = 14), CLL (n = 19), solid organ transplant (n = 94), solid tumor (n = 39), and immunosuppressive treatment (n = 57). Compared with other underlying diseases, PCP related to CLL was closer to PCP related to AIDS presentation (long duration of symptoms before diagnosis, high level of dyspnea, and low oxygen saturation at diagnosis). Day 30 mortality was associated with underlying disease, oxygen flow, and shock at ICU admission. PCP presentations may vary according to the underlying reason for immunosuppression. Response to treatment and adjuvant steroid therapy should be analyzed regarding this result.

Abstract: BACKGROUND Programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1) immune checkpoint blockade is efficacious in certain cancer therapies. OBJECTIVES The present study aimed to provide a picture about the development of innate and adaptive immune responses upon PD-L1 blockade in treating chronic murine AE. METHODS Immune treatment started at 6 weeks post E. multilocularis-infection, and was maintained for 8 weeks with twice per week anti-PD-L1 administration (intraperitoneal). The study included an outgroup-control with mice perorally medicated with albendazole five days/week, and another one with both treatments combined. Assessment of treatment efficacy was based on determining parasite weight, innate and adaptive immune cell profiles, histopathology, and liver tissue cytokine levels. RESULTS/CONCLUSIONS Findings showed that the parasite load was significantly reduced in response to PD-L1 blockade, and this blockade a) contributed to T cell activity by increasing CD4+ /CD8+ effector T cells, and decreasing Tregs; b) had the capacity to re-store DCs and Kupffer cells/Macrophages; c) suppressed NKT and NK cells; and thus d) lead to an improved control of E. multilocularis infection in mice. This study suggests that the PD-L1 pathway plays an important role by regulating adaptive and innate immune cells against E. multilocularis infection, with significant modulation of tissue inflammation.

Abstract: AIMS Alveolar echinococcosis (AE) is characterized by a chronically progressing hepatic injury caused by Echinococcus multilocularis. Surgery presently remains the best curative option. Currently, biological predictive features derived from the resected specimens are not suitable to assess surgery efficacy. The present study was designed to investigate whether a selection of markers measured on the resected specimens exhibits predictive features related to parasite viability, or to a total elimination of the parasite, in addition to serological markers. METHODS AND RESULTS In a collaboration between two centers, one in France (Besancon), and one in Switzerland (Bern), samples from 40 AE patients were analyzed by microarray and serology techniques, individually. Paired serum samples before and after surgery were obtained for 26 patients. In the sera, a significant decrease of PD-L1 levels was observed after surgery, in addition to anti-Em18 levels. In the liver tissue, low levels of Cluster of Differentiation (CD)-3 were correlated with the absence of serum anti-Em18 after surgery. CONCLUSION This study showed PD-L1 is promising as a potential serological marker, and further confirmed the performance of anti-Em18 serology. Further studies on a larger cohort is needed to confirm the utility of performing systematically microarray on resected liver tissue.

Abstract: Background The classification of invasive pulmonary aspergillosis (IPA) issued by the European Organization for the Research and Treatment of Cancer/Mycoses Study Group Education and Research Consortium (EORTC/MSGERC) is used for immunocompromised patients. An alternative algorithm adapted to the intensive care unit (ICU) population has been proposed (AspICU), but this algorithm did not include microbial biomarkers such as the galactomannan antigen and the Aspergillus quantitative PCR. The objective of the present pilot study was to evaluate a new algorithm that includes fungal biomarkers (BM-AspICU) for the diagnosis of probable IPA in an ICU population. Patients and methods Data from 35 patients with pathology-proven IPA according to European Organization for the Research and Treatment of Cancer/Mycosis Study Group (EORTC/MSGERC)-2008 criteria were extracted from the French multicenter database of the Invasive Fungal Infections Surveillance Network (RESSIF). The patients were investigated according to the AspICU algorithm, and the BM-AspICU algorithm in analyzing the clinical, imaging, and biomarker data available in the records, without taking into account the pathology findings. Results Eight patients had to be excluded because no imaging data were recorded in the database. Among the 27 proven IPAs with complete data, 16 would have been considered as putative IPA with the AspICU algorithm and 24 would have been considered as probable IPA using the new algorithm BM-AspICU. Seven out of the 8 patients with probable BM-AspICU IPA (and not classified with the AspICU algorithm) had no host factors and no Aspergillus-positive broncho-alveolar lavage fluid (BALF) culture. Three patients were non-classifiable with any of the two algorithms, because they did not have any microbial criteria during the course of the infection, and diagnosis of proven aspergillosis was done using autopsy samples. Conclusion Inclusion of biomarkers could be effective to identify probable IPA in the ICU population. A prospective study is needed to validate the routine application of the BM-AspICU algorithm in the ICU population.

Abstract: Aims Following treatment, cystic echinococcosis (CE) exhibits a relatively high relapse rate. Here, we evaluated the value of soluble programmed death-1 (sPD-1), sPD-1 ligand (sPD-L1) and anti-recP29 antibody concentrations, as predictors of early surgical treatment outcome in young CE-affected patients. Methods and results This prospective study included 59 Tunisian children (177 plasmas ), where CE was surgically treated and monitored for 3 post-operative years. Based on CE post-surgical development, patients were clustered into a "No relapsed" CE (NRCE; n = 39) and a "Relapsed" CE (RCE; n = 20) group. Serum levels of sPD-1, sPD-L1 and anti-recP29 IgG were measured using ELISA. In the NRCE group, sPD-1, sPD-L1 and anti-recP29 IgG concentrations were significantly lower at D365 than at D30. By contrast, in the RCE group, no significant difference was observed between D0, D30 and D365.When considering individual variations, the probability to be "relapse-free" was 67% and 73% when anti-recP29 IgG and sPD-L1 level, respectively, decreased between D30 and D365. The probability to be "relapse-free" was 86% when the sPD-1 level decreased between D30 and D365 (p= 0.003; Chi-square test). Conclusion sPD-1 may be a useful biomaker for the early evaluation of surgical procedure efficacy in pediatric CE cases.

Abstract: International audience; Background: Microsporidiosis has been largely reported in patients with acquired immunodeficiency syndrome, but emerged as a cause of persistent diarrhea in solid organ transplant patients.Methods: Through the French Microsporidiosis Network and the Groupe français de recherche en greffe de foie, we collected all microsporidiosis cases identified in liver transplant patients between 1995 and 2020 in France.Results: We identified 24 liver transplant recipients with microsporidiosis. Sex ratio was balanced and median age was 58.8 (3.5-83.5) years (there were 4 children). Microsporidiosis occurred at a median time of 3.9 (0.1-18.9) years post-transplant. Median duration of diarrhea before diagnosis was 22 days (12-45). Therapeutic care included immunosuppressive therapy changes in 20 patients, as follows: stop cyclosporine or tacrolimus (n = 2), dose reduction of cyclosporine or tacrolimus (n = 12), stop MMF (n = 5), and dose reduction of corticosteroids (n = 1). In addition, 15 patients received specific therapy against microsporidiosis: fumagillin (n = 11) or albendazole (n = 4). Median duration of treatment was 14 days (8-45 days). Finally, 7 patients had immunosuppressive treatment tapering only. Microsporidiosis was complicated by renal failure in 15 patients, requiring dialysis in one case. Two patients had infection relapse. No patient presented proven rejection within the 3 months after microsporidiosis. None of the patients died within the 3 months after microsporidiosis.Conclusions: Microsporidiosis is a very rare infection after liver transplantation but can induce severe dehydration and renal failure. Therefore, it must be systematically sought in any case of persistent diarrhea after first line screening of frequent infectious causes.

Abstract: BACKGROUND Trichosporonosis is a rare invasive infection in humans mainly due to Trichosporon asahii, and especially recovered from patients having haematological malignancy. Since 2012, IGS1 region sequencing is used as a genotyping method to distinguish isolates, with high frequency of one haplotype worldwide and a geographic specificity for some haplotypes. OBJECTIVES We compared the IGS1 genotyping method and whole genome sequencing (WGS) to study the relationship between clinical isolates involved in two grouped cases in France. METHODS IGS1 sequencing and antifungal susceptibility testing were performed for 54 clinical isolates. Clinical data for 28 isolates included in surveillance programs were analysed. Whole genome was sequenced for 32 clinical isolates and the type strain. RESULTS All isolates were intrinsically resistant to flucytosine, while voriconazole had the most potent in vitro activity. The majority of the isolates was recovered from patients with haematological malignancies (42.86%), with a high proportion of children (

Abstract: AIMS Alveolar echinococcosis is a severe chronic helminthic infection that mimics a tumour-like disease. This study aimed at investigating in vitro interactions between Echinococcus multilocularis vesicular fluid (VF) and different immune checkpoints (PD-1/PD-L1, CTLA-4, LAG-3 and TIM-3). METHODS AND RESULTS Peripheral blood mononuclear cells (PBMC) from healthy blood donors were isolated by Ficoll. Natural killer (NK) cells were selected. Each type of cell was stimulated individually with E. multilocularis-VF. Expression of the different immune checkpoints was measured by flow cytometry on day 3 and day 6; all supernatants were used for immunoassays. Cells and supernatants from 22 healthy donors were analysed. A significant increase of PD-1, PD-L1, LAG-3 and TIM-3 was observed upon E. multilocularis-VF exposure for NK cells on day 3 (P

Abstract: International audience; A survey of mycology laboratories for antifungal susceptibility testing (AFST) was undertaken in France in 2018, to better understand the difference in practices between the participating centers and to identify the difficulties they may encounter as well as eventual gaps with published standards and guidelines. The survey captured information from 45 mycology laboratories in France on how they perform AFST (number of strains tested, preferred method, technical and quality aspects, interpretation of the MIC values, reading and interpretation difficulties). Results indicated that 86% of respondents used Etest as AFST method, with a combination of one to seven antifungal agents tested. Most of the participating laboratories used similar technical parameters to perform their AFST method and a large majority used, as recommended, internal and external quality assessments. Almost all the participating mycology laboratories (98%) reported difficulties to interpret the MIC values, especially when no clinical breakpoints are available. The survey highlighted that the current AFST practices in France need homogenization, particularly for MIC reading and interpretation.

Abstract: International audience; Tick-borne encephalitis (TBE) cases have been emerging in Europe. The Franche-Comte area, in northeastern France, borders Switzerland, but the two countries differ in their approach to TBE surveillance and prevention. Because family physicians (FPs) are in direct contact with the local population, at-risk of infected tick bites, they need to be well aware of TBE epidemiology and management. An observational survey was performed in 2019 in order to investigate Franche-Comte physicians' knowledge and vaccination practices with regard to TBE. Standardized online questionnaires were sent to a list of FPs practicing in Franche-Comte. The questionnaires included socio-demographic details, questions about TBE knowledge, symptomatology and vaccination. The response rate was 14.7%. FPs practicing in rural areas reported a significantly higher frequency of consultations for tick bites. While 81% of FPs indicated that they had some knowledge about TBE, only 20% were at ease with its clinical symptomatology. Thirty-one % of the FP participants performed TBE vaccinations. A general lack of knowledge about TBE and its clinical symptoms was observed in this survey. FPs play an essential role in screening and preventing TBE, especially those practicing in rural areas and in areas bordering Switzerland.

Abstract: Background Aspergillus spp. of section Usti (A. ustus) represent a rare cause of invasive aspergillosis (IA). This multicenter study describes the epidemiology and outcome of A. ustus infections. Methods Patients with A. ustus isolated from any clinical specimen were retrospectively identified in 22 hospitals from 8 countries. When available, isolates were sent for species identification (BenA/CaM sequencing) and antifungal susceptibility testing. Additional cases were identified by review of the literature. Cases were classified as proven/probable IA or no infection, according to standard international criteria. Results Clinical report forms were obtained for 90 patients, of whom 27 had proven/probable IA. An additional 45 cases were identified from literature review for a total of 72 cases of proven/probable IA. Hematopoietic cell and solid-organ transplant recipients accounted for 47% and 33% cases, respectively. Only 8% patients were neutropenic at time of diagnosis. Ongoing antimold prophylaxis was present in 47% of cases. Pulmonary IA represented 67% of cases. Primary or secondary extrapulmonary sites of infection were observed in 46% of cases, with skin being affected in 28% of cases. Multiple antifungal drugs were used (consecutively or in combination) in 67% of cases. The 24-week mortality rate was 58%. A. calidoustus was the most frequent causal agent. Minimal inhibitory concentrations encompassing 90% isolates (MIC90) were 1, 8, >16, and 4 µg/mL for amphotericin B, voriconazole, posaconazole, and isavuconazole, respectively. Conclusions Aspergillus ustus IA mainly occurred in nonneutropenic transplant patients and was frequently associated with extrapulmonary sites of infection. Mortality rate was high and optimal antifungal therapy remains to be defined.

Abstract: International audience; We present a case of invasive fungal co-infection in a young patient treated for an acute myeloid leukemia and having undergone a twice-haploid matched unrelated donor hematopoietic stem cell transplantation (HSCT) with two different donors. A mucormycosis diagnosis was made shortly after the patient's admission using imagery and specific Mucorales qPCR which was treated with liposomal amphotericin B and posaconazole. Twenty days later, a blood culture was positive for Fusarium solani, and disseminated cutaneous lesions appeared. The antifungal treatment was changed to liposomal amphotericin B and voriconazole. Thanks to a complete hematological reconstitution and despite a co-infection with two aggressive filamentous opportunistic fungi, the patient recovered. We took advantage of this clinical case to test a specific Fusarium solani qPCR, which proved to be promising when performed retrospectively on some of the patient samples.

This case illustrates that HP diagnosis remains challenging, especially in patients with another pulmonary disease, and that serodiagnosis contributes to identifying the precise microorganism involved. It also demonstrates that P. oleovorans is an important secondary aetiological agent in MWF-HP, less known than Mycobacterium immunogenum.

Abstract: Aspergillus fumigatus is the predominant etiological agent of invasive aspergillosis (IA), a difficult-to-manage fungal disease associated with a high case fatality rate. Azole antifungals, particularly voriconazole, have significantly improved the survival rate of patients with IA. However, the clinical advances made possible through the use of medical azoles could be threatened by the emergence of azole-resistant strains which has been reported in an ever-increasing number of countries over the last 10 years. The major resistance mechanism, that combines point mutation(s) in the coding sequence of cyp51A gene and an insertion of a tandem repeat in the promoter region of this gene which leads to its overexpression (TR34/L98H and TR46/Y121F/T289A), is presumed to be of environmental origin. However, the emergence of clinical and environmental azole-resistant strains without the cyp51A gene mutation suggests that other mechanisms could also be responsible for azole resistance (for example, overexpression of efflux pumps). The development of resistance may be linked to either long-term use of azole antifungals in patients with chronic aspergillosis (patient-acquired route) or selection pressure of the fungicides in the environment (environmental route). The fungicide-driven route could be responsible for resistance in azole-naive patients with IA. This literature review aims to summarize recent findings, focusing on the current situation of azole-resistance in A. fumigatus, and provides better understanding of the importance of the environmental route in resistance acquisition.

Abstract: International audience; We propose a strategy for serodiagnosis of hypersensitivity pneumonitis (HP): 1) question patients about their private or occupational activity, or visit him on site; 2) select panels of six somatic specific antigens appropriate for each type of exposure; 3) and use ELISA to test concomitantly two recombinant antigens highly specific to Farmer's lung, Metalworking-fluid HP, and for Bird fancier's lung. The serodiagnosis provides an immunological argument that may complete radiological, functional lung exploration and clinical features; 4) If the serodiagnosis is negative but the suspicion of HP is strong, a microbial analysis of the patient's specific exposure is conducted; 5) "A la carte" antigens are produced from the microorganisms isolated in the patient's environment sample and tested; 6) Finally, the patient may be asked to undergo a specific inhalation challenge with the offending antigens in a safety cabin, or to avoid his usual environment for a few days.

Abstract: International audience; Rapid identification of Candida species is important for appropriate antifungal therapy of fungemia. The matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) system is a useful tool to identify bacteria and yeasts. In this study, we evaluated the feasibility of identifying yeasts after a short-term incubation on a solid medium. We tested 24 strains of eight Candida species. Blood culture bottles were spiked with a calibrated suspension of each Candida strain. Three different culture media, two types of blood culture bottles and three different incubation time points were tested. A multivariable random-effects logistic regression analysis was performed for determining factors independently associated with a successful MALDI-TOF MS identification. One-hundred and thirty-one out of 432 MALDI-TOF MS analyses (30%) exhibited a score ≥ 1.7. The performance of the technique varied across Candida species. Factors associated with a successful identification were the use of a chromogenic Candida medium and the time points 4 and 5 h. Using the factors 'chromogenic Candida medium' and time point 5 h the global performance of identification reached 60% and a mean MALDI-TOF score of 1.78. Identifying yeasts after a short-term incubation on a solid medium seems possible, especially when using a chromogenic Candida medium and respecting at least 5 h of incubation. This assay was a first step and needs to be completed using more strains, various chromogenic Candida medium and maybe also testing a longer culture time such as 6 h.

Abstract: International audience; The growth potential of the tumour-like Echinococcus multilocularis metacestode (causing alveolar echinococcosis, AE) is directly dependent upon the nature/function of the periparasitic adaptive host immune-mediated processes. PD-1/PD-L1 pathway (programmed cell death 1), which inhibits lymphocytic proliferation in tumour development, is over-expressed at the chronic stage of AE. We tested the impact of a PD-1/PD-L1 pathway blockade on the outcome of both chronic AE (intraperitoneal metacestode inoculation, secondary AE and SAE) and acute AE (peroral egg infection, primary AE and PAE). To assess the parasite proliferation potential, we measured parasite mass weight for SAE and liver lesion number for PAE. In both models, the parasite load was significantly decreased in response to anti-PD-L1 antibody treatment. In SAE, anti-PDL1 administration was associated with increased Th1 response parameters and decreased Treg responses, while in PAE anti-PDL1 administration was associated with fewer lesions in the liver and decreased Treg/Th2 responses. Our findings highly suggested that a PD-1/PD-L1 pathway blockade triggered the host immune responses in favour of an immune-mediated control of E. multilocularis proliferation. Based on this, future studies that combine PD-1/PD-L1 blockade with a parasitostatic albendazole medication may yield in a putatively curative therapeutic approach to control alveolar echinococcosis.

Abstract: International audience; Dairy farming is a risk factor for chronic obstructive pulmonary disease (COPD). The aim was to determine predictive markers either in blood samples or in dwelling dust samples by comparing COPD and healthy controls with or without farming activity. Dust was collected and analyzed by real-time quantitative PCR. ELISA and DELFIA® were performed to assay the level of specific IgG and IgE of 10 targeted microorganisms. The dwelling exposure of farmers was higher than in the non-farmers (Especially Eurotium amstelodami and Lichtheimia corymbifera). The IgG response against Wallemia sebi and Saccharopolyspora rectivirgula was more often higher in the farmers than the non-farmers. However, exposure and sensitization to the microorganisms tested cannot explain the occurrence of COPD in the dairy farmers' population. COPD development is probably caused by multiple factors associated with exposure over a period of several years.

Abstract: International audience; Galactomannan antigen (GM) testing has been used for decades to screen immunocompromised patients for invasive aspergillosis (IA). Recent publications suggested that using a higher cut-off value than 0.5 in bronchoalveolar lavage fluid (BALF) could be more discriminant for hematology patients. We retrospectively analyzed the values of GM in BALF over 7 years (from 2010 to 2016). Performance indicators of the GM in BALF, according to three different cut-off values (0.5, 0.8, 1.5), were calculated using Stata 14.1. IA classification for hematology patients was based on European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) criteria, as defined in 2008. A number of 716 GM were performed on BALF from 2010 to 2016 (597 patients) and 66 were positive (> 0.5). Among these 597 patients, 27 IA were diagnosed, 13 with a positive GM in BALF, 9 with a negative GM in BALF, and 5 unclassified IA (ICU patients). The analysis of performance indicators, based on our local data, did not demonstrate any significant difference using a higher cut-off value of GM in BALF. This result may be explained by the local recruitment of patients and by pre-analytic variations during BALF realization.

Abstract: International audience; Cryptosporidiosis is a common disease in children and immunodeficient individuals. In 2006, a national network was set up on the surveillance of human cryptosporidiosis in France. Since January 2015, the 41 tertiary care hospitals and the 3 private laboratories of the French National Network on the surveillance of human cryptosporidiosis have been able to declare confirmed cases of cryptosporidiosis online. Between 2015 and 2017, 210 cases of cryptosporidiosis were declared in immunodeficient patients in France; Cryptosporidium parvum and Cryptosporidium hominis represented 66% and 22% of cases, respectively. A peak was observed in autumn. Cryptosporidiosis occurred mainly in a context of solid organ transplantation (SOT) (49%) and of HIV infection (30%). In SOT recipients, cryptosporidiosis appeared more frequently in the first 6 months post transplantation. Regarding cases declared in SOT recipients, mycophenolate mofetil was used in 68%. A mortality rate of 6% was observed. Present results underline the importance of screening for cryptosporidiosis in immunocompromised patients suffering from diarrhea, especially in the course of major cell mediated immunodeficiency or even systematic screening before SOT. Exclusive Cryptosporidium free water feeding could be suggested during major cell mediated immunodeficiency.

Abstract: International audience; Mucormycosis is an invasive mold infection, frequently fatal in immunocompromised patients. We report the case of a patient with chronic lymphocytic leukemia admitted to the hematology unit for febrile aplasia. Pulmonary lesions suggesting a fungal infection expanded/increased despite a combination of posaconazole and liposomal amphotericin B. The fungal biomarkers performed repeatedly were negative. At D65 after chemotherapy a bronchial biopsy was positive for Cunninghamella bertholletiae. The patient died despite appropriate antifungal management. A qPCR targeting Cunninghamella was developed a posteriori, and a retrospective analysis showed that a sample was positive more than 30 days before culture-based identification could be made.

Abstract: International audience; We present 2 fatal cases of invasive fungal disease with isavuconazole treatment failure in immunocompromised patients: one with a TR34-L98H azole-resistant Aspergillus fumigatus isolate and the other a Rhizomucor-A. fumigatus co-infection. Such patients probably require surveillance by galactomannan antigen detection and quantitative PCRs for A. fumigatus and Mucorales fungi.

Abstract: Early diagnosis and treatment are essential to improving the outcome of mucormycosis. The aim of this retrospective study was to assess the contribution of quantitative PCR detection of Mucorales DNA in bronchoalveolar lavage fluids for early diagnosis of pulmonary mucormycosis. Bronchoalveolar lavage fluid samples (n = 450) from 374 patients with pneumonia and immunosuppressive conditions were analyzed using a combination of 3 quantitative PCR assays targeting the main genera involved in mucormycosis in France (Rhizomucor, Mucor/Rhizopus, and Lichtheimia). Among these 374 patients, 24 patients had at least one bronchoalveolar lavage fluid sample with a positive PCR; 23/24 patients had radiological criteria for invasive fungal infections according to consensual criteria; 10 patients had probable or proven mucormycosis, and 13 additional patients had other invasive fungal infections (4 probable aspergillosis, 1 proven fusariosis, and 8 possible invasive fungal infections). Only 2/24 patients with a positive PCR result on a bronchoalveolar lavage fluid sample had a positive Mucorales culture. PCR was also positive on serum in 17/24 patients. In most cases, a positive PCR result was first detected using sera (15/17). However, a positive PCR on bronchoalveolar lavage fluid was the earliest and/or the only biological test revealing mucormycosis in 4 patients with a final diagnosis of probable or proven mucormycosis, 3 patients with probable aspergillosis, and one patient with a possible invasive fungal infection. Mucorales PCR performed on bronchoalveolar lavage fluid could provide additional support for earlier administration of Mucorales-directed antifungal therapy, thus improving the outcome of lung mucormycosis cases.

Abstract: International audience; Invasive fungal infections (IFIs) play an important role in the mortality of immunocompromised patients. The pediatric hematology department (PHD) at Besançon University Hospital has relocated 3 times: (1) from a building without an air filtration system (B1), (2) to a renovated building with low air pressure (B2), and (3) to a new building with high air pressure and high-efficiency particulate air filters (B3). This study aimed to investigate how these relocations influenced the fungal exposure risk for the PHD's patients.; Air samples were taken monthly in patient rooms and weekly in corridors. The detection of opportunistic fungi species was used to assess IFI risk. Data were analyzed using univariate and multivariate random-effects negative binomial regression.; A total of 1,074 samples from 29 rooms over a 10-year period showed that renovation of an old building with a basic ventilation system did not lead to a significant improvement of air quality (P = .004, multivariate analysis). Among factors linked to higher risk of patient rooms mold contamination was fungal contamination of the corridors (P

Abstract: Introduction Tick bites, which may lead to Lyme disease, often prompt patients to consult their primary care physicians (PCPs). The aim of the present study was to assess how and how often PCPs in the Franche-Comte region of France manage tick bites. Material and methods Standardized questionnaires were sent to a random sample of 400 PCPs in the Franche-Comte region, requesting their voluntary and anonymous participation. The questionnaires collected socio-demographic details and practice-related information about tick-bite prophylaxis, Lyme serology, and tick-borne encephalitis vaccination. Results The crude response rate was 54.5% of the PCPs contacted. Tick-bite prophylaxis was prescribed as per current guidelines. However, Lyme serology seemed to be largely overprescribed for tick bites and in case of erythema migrans. A clear lack of knowledge about tick-borne encephalitis vaccination was also observed. Discussion PCPs provide the first line of care for patients presenting with tick bites. This study showed that although PCPs of the Franche-Comte region manage tick bites as per current guidelines, they need further training on Lyme serology limitations and availability of tick-borne encephalitis vaccination.

Abstract: International audience; Alveolar echinococcosis is a severe chronic helminthic disease that mimics slow-growing liver cancer. The immune evasion strategy of Echinococcus multilocularis Leuckart, 1863 remains poorly understood. The aim of this study was to investigate in vitro the impact of E. multilocularis vesicular fluid (Em-VF) on peripheral blood mononuclear cells (PBMC) and on natural killer (NK) cells. PBMC and NK cells were exposed to Em-VF (1 µg/ml) during six days. The effect of Em-VF was assessed on CD69, viability and proliferation, and on and transforming growth factor β (TGF-β), interferon γ (IFN-γ), interleukin 17 (IL-17) and interleukin 10, using flow cytometry and ELISA, respectively. Exposure to Em-VF had no bearing on PBMC's viability, proliferation and expression of CD69. In contrast, higher levels of IL-17 at day three and of TGF-β at day six were observed in PBMC supernatant after exposure to Em-VF (p < 0.05, Wilcoxon signed-rank test). Exposure to Em-VF induced a significant decrease of CD69 expression of NK cells at day three and a significant decrease of proliferation of NK cells at day six (p < 0.05, Wilcoxon signed-rank test). In contrast, NK cells viability and levels of cytokines did not vary significantly over Em-VF stimulation. Exposure to Em-VF had a significant bearing on activation and proliferation of NK cells. NK cells may play an important role in the immune response of the host against E. multilocularis.

Abstract: International audience; BACKGROUND: Invasive mould infections represent a threat for high-risk patients hospitalized in haematology units. French guidelines recommend that fungal aerocontamination monitoring should be performed quarterly. Since 2002, Besançon University Hospital has expanded to include several new buildings. Consequently, environmental surveys have been re-inforced and are now performed on a weekly basis. AIM: To retrospectively assess the contribution of fungal aerocontamination measurement in haematology corridors and main hospital corridors as a sentinel to assess fungal exposure and risk of invasive mould infections. METHODS: Over a 10-year period, 2706 air samples were taken by impaction every week in the same locations in haematology corridors and main hospital corridors. All fungal species were identified. The Haematology and Hospital Hygiene Departments were alerted systematically whenever a peak of opportunistic species was detected and corrective action was planned. Since 2007, each case of invasive aspergillosis has been reported to the French health authorities. Cuzick's test, Mann-Kendall's trend test, autocorrelation and Spearman's correlation rank test were used for statistical analysis. FINDINGS: Over 10 years of surveillance, 12 peaks of Aspergillus fumigatus (>40colony-forming units/m(3)) were observed in the main hospital corridors, and A. fumigatus contamination was detected up to six times per year in the haematology corridors. In order to limit fungal exposure, the decision was made to perform additional checks on ventilation systems and heating, increase biocleaning and develop clear instructions. CONCLUSION: No significant link was observed between A. fumigatus detection and invasive aspergillosis. Weekly surveys have helped to improve the vigilance of the medical teams. Nevertheless, 58 cases of invasive aspergillosis have been identified since 2007.

Abstract: Contrary to hospital exposure, little is known about the indoor fungal exposure of hematology patients at home. The aim of our study was to investigate the mold exposure of hematology patients both at home and at hospital to assess their invasive aspergillosis (IA) risk. Fungal exposure was assessed by quantifying opportunistic molds at hospital during hospitalization and in homes of 53 hematology patients. IA was diagnosed in 13 of 53 patients and invasive fungal infection (IFI) in one patient. In hospital, no opportunistic species, or low levels of opportunistic species, were found in 98% of weekly controls. Only 2% of hematology intensive care unit (ICU) controls showed a high level of Aspergillus fumigatus spores in corridor air. Five patients IA were hospitalized during these periods. Seven dwellings of 53 (5/14 dwellings of patients with IA/IFI and 2/39 dwellings of non-IA patients) had a percentage of A. fumigatus and Aspergillus flavus to total mold (significant predictor variable of IA/IFI in our study, general linear model, P-value = 0.02) as high as 15%. Maintaining a 'zero Aspergillus' goal at hospital is essential, and establishing specific and individually opportunistic mold monitoring at home could help to further reduce the IA risk through continuous surveillance.This study emphasizes the fact that preventive measures should not be aimed only at the hospital setting: among patients diagnosed with invasive aspergillosis/invasive fungal infection (IA/IFI), 5 of 14 (36%) were exposed to opportunistic fungal species at home exclusively. Moreover, four of these five patients were living in homes having the highest percentage of Aspergillus fumigatus and Aspergillus flavus (15%), one of which had 48% of A. fumigatus. Therefore, our work supports the need for a counselor to carry out an environmental survey in patients’ homes.
