Laboratory practices for the diagnosis and management of mucormycosis in France, 2024.

This study investigates the diagnostic practices for mucormycosis among 30 French University Hospital mycology laboratories, in 2024. All laboratories perform both direct examination and culture, with fluorescent brighteners being the most commonly used method for direct examination. While 77 % of the participating laboratories routinely identify Mucorales to the species level, with 70 % having adopted Mucorales-specific quantitative PCR, primarily for the diagnosis of invasive fungal infections.

Invasive fungal diseases in patients with autoimmune diseases: a case series from the French RESSIF network.

Objectives: We aimed to describe patients with autoimmune diseases (AID) developing invasive fungal disease (IFD) and identify factors associated with short-term mortality.

Methods: We analysed cases of IFD associated with AID from the surveillance network of invasive fungal diseases (Réseau de surveillance des infections fongiques invasives, RESSIF) registry of the French national reference centre for invasive mycoses. We studied association of AID-specific treatments with 30-day mortality.

Candida haemulonii complex, an emerging threat from tropical regions?

Background: Candida haemulonii complex-related species are pathogenic yeasts closely related to Candida auris with intrinsic antifungal resistance, but few epidemiological data are available.

Methodology/principal Findings: We analyzed clinical and demographic characteristics of patients with fungemia due to C. haemulonii complex and related species (C.

Active Surveillance Program to Increase Awareness on Invasive Fungal Diseases: the French RESSIF Network (2012 to 2018).

The French National Reference Center for Invasive Mycoses and Antifungals leads an active and sustained nationwide surveillance program on probable and proven invasive fungal diseases (IFDs) to determine their epidemiology in France. Between 2012 and 2018, a total of 10,886 IFDs were recorded. The incidence increased slightly over time (2.

COVID-19-Associated Pulmonary Aspergillosis, Fungemia, and Pneumocystosis in the Intensive Care Unit: a Retrospective Multicenter Observational Cohort during the First French Pandemic Wave.

The aim of this study was to evaluate diagnostic means, host factors, delay of occurrence, and outcome of patients with COVID-19 pneumonia and fungal coinfections in the intensive care unit (ICU). From 1 February to 31 May 2020, we anonymously recorded COVID-19-associated pulmonary aspergillosis (CAPA), fungemia (CA-fungemia), and pneumocystosis (CA-PCP) from 36 centers, including results on fungal biomarkers in respiratory specimens and serum. We collected data from 154 episodes of CAPA, 81 of CA-fungemia, 17 of CA-PCP, and 5 of other mold infections from 244 patients (male/female [M/F] ratio = 3.

Dermatophytic onychia: Effectiveness of rapid immunochromatographic diagnostic testing directly on samples compared to culture.

Background: Until now, definite diagnosis of dermatophytic onychia has been made by taking a nail sample and placing it in culture. The result is usually obtained only after 2 to 3weeks. More recently, diagnosis within a few minutes after sampling has become possible thanks to an immunochromatography technique developed in Japan and now available in France: the Diafactory Tinea Unguium® test strip (Biosynex, France).

Imported schistosomiasis in Paris region of France: A multicenter study of prevalence and diagnostic methods.

Background: There are few data on imported schistosomiasis - especially in children. The objectives of the present study were to estimate the prevalence of imported schistosomiasis in at-risk children in the greater Paris region of France and to compare diagnostic methods.

Method: Children at risk of schistosomiasis who consulted or were hospitalized in four hospitals in the greater Paris region were prospectively included.

Antifungal susceptibility testing practices in mycology laboratories in France, 2018.

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.

Acute paraplegia due to schistosomiasis: an uncommon cause in developed countries.

We present a case of a young African migrant from Guinea-Conakry presented to a French emergency department with burning pain in both feet for 2 days. The symptoms progressed to limb paraparesis with sphincter disorders. A magnetic resonance imaging (MRI) scan showed a hyperintense spinal cord lesion without contrast enhancement extending from the T6 vertebrae to the conus medullaris.

Imported Schistosomiasis in Children: Clinical, Diagnostic Aspects And Outcome in 5 Tertiary Hospitals in France.

The objective of this retrospective study is to describe imported schistosomiasis in children in the Paris region between 2010 and 2015. Forty children with a diagnosis of schistosomiasis were included. Thirty-seven (93%) had a chronic urinary form with hematuria.

in the cystic fibrosis lung: pros and cons of azole therapy.

is the main fungus cultured in the airways of patients with cystic fibrosis (CF). Allergic bronchopulmonary aspergillosis occurs in ~10% of CF patients and is clearly associated with airway damage and lung function decline. The effects of colonization in the absence of allergic bronchopulmonary aspergillosis are less well established.

Pulmonary aspergillosis.

Aspergillosis is a mycotic disease usually caused by Aspergillus fumigatus, a saprophytic and ubiquitous airborne fungus. Aspergillus-related lung diseases are traditionally classified into four different forms, whose occurrence depends on the immunologic status of the host and the existence of an underlying lung disease. Allergic broncho-pulmonary aspergillosis (ABPA) affects patients with asthma or cystic fibrosis.

Late occurrence of Histoplasma duboisii cutaneous and pulmonary infection 18 years after exposure.

We report an imported case of Histoplasma capsulatum var. duboisii (H. duboisii) infection in a white French woman revealed by cutaneous lesions of the scalp, 18 years after her last stay in West and Central Africa.

Longer incubation times for yeast fungemia: importance for presumptive treatment.

Isolation rates of Candida glabrata at ≤2 days were 8.9% and 34.8% at >2 days; for Cryptococcus neoformans, they were 0.

Comparison of real-time PCR with conventional methods to detect dermatophytes in samples from patients with suspected dermatophytosis.

A PCR detecting dermatophytes within a short turnaround time would significantly enhance the management of patients with suspected dermatophytosis. This study aimed at comparing the results of a real-time PCR assay with those of the conventional diagnostic (direct microscopy and culture) performed by a dermatologist working in a medical mycology laboratory for the detection of dermatophytes in nail and skin samples. A total of 112 specimens (54 nail and 58 skin) were collected from 52 patients with one to four suspected dermatophytosis lesions.

Peripheral blood and bone marrow cells cultivated in Novy-Mcneal-Nicolle medium for visceral leishmaniosis diagnosis revealed Rhodotorula fungemia in an AIDS patient with lymphoma.

Rhodotorula is a ubiquitous yeast that can infect immunocompromised patients. Here, we present the case of a 45-year-old patient with AIDS who developed a Rhodotorula mucilaginosa fungemia. The patient had a past history of visceral leishmaniasis (VL) and was hospitalised to receive chemotherapy for a B-cell lymphoma of the sinonasal cavities.

High prevalence of azole-resistant Aspergillus fumigatus in adults with cystic fibrosis exposed to itraconazole.

Aspergillus fumigatus is the most frequent fungus found in the sputum of cystic fibrosis (CF) subjects. Itraconazole is prescribed for allergic bronchopulmonary aspergillosis (ABPA) or Aspergillus bronchitis in CF subjects. We hypothesized that A.
