A new analytical method was developed for the routine Therapeutic Drug Monitoring of 8 antifungals compounds in 50μL of plasma: isavuconazole (ISZ), voriconazole (VRZ), posaconazole (PSZ), fluconazole (FCZ), caspofungin (CSF), flucytosine (5FC), itraconazole (ITZ) and its metabolite OH-itraconazole (OH-ITZ). After adding 50μL of the internal standard, which consisted in a mixture of the deuterated isotopes of the quantified compounds, the sample treatment consisted in a simple protein precipitation with 400μL of acetonitrile. Five microliters of the supernatant were directly injected into the chromatographic system.

is a major pathogenic yeast in humans that is known to rapidly acquire resistance to triazole and echinocandin antifungal drugs. A mutator genotype ( polymorphism) inducing a mismatch repair defect has been recently proposed to be responsible for resistance acquisition in clinical isolates. Our objectives were to evaluate the prevalence of antifungal resistance in a large cohort of patients in Saint-Louis hospital, Paris, France, some of whom were pre-exposed to antifungal drugs, as well as to determine whether polymorphisms are associated with an increased rate of fluconazole or echinocandin resistance.

Chronic disseminated candidiasis (CDC) is a rare and difficult-to-treat invasive fungal disease occurring mainly after prolonged and profound neutropenia. We describe the case of a 59-year-old man successfully treated with thalidomide for CDC recurrences after an autologous transplantation. We add evidence of the effectiveness of immunomodulatory drugs to manage inflammatory reconstitution immune syndrome-related refractory CDC.

Background: Invasive aspergillosis (IA) is a major cause of invasive fungal infection in kidney transplant recipients (KTR), and it has a high mortality rate. However, its impact on patients and graft survival has not been well defined in the current era of voriconazole first-line therapy.

Methods: We retrospectively collected all cases of KTR-associated IA occurring at Necker Enfants Malades Hospital, Paris, from 2003 to 2013.

Pneumocystis jirovecii is an unculturable fungus and the causative agent of Pneumocystis pneumonia, a life-threatening opportunistic infection. Although molecular diagnosis is often based on the detection of mtLSU rRNA mitochondrial gene, the number of copies of mitochondrial genes had not been investigated. We developed and optimized six real-time PCR assays in order to determine the copy number of four mitochondrial genes (mtSSU rRNA, mtLSU rRNA, NAD1, and CYTB) in comparison to nuclear genome (DHPS and HSP70) and tested 84 bronchoalveolar fluids of patients at different stages of the infection.

The 5th European Conference on Infections in Leukaemia (ECIL-5) meeting aimed to establish evidence-based recommendations for the prophylaxis of Pneumocystis jirovecii pneumonia (PCP) in non-HIV-infected patients with an underlying haematological condition, including allogeneic HSCT recipients. Recommendations were based on the grading system of the IDSA. Trimethoprim/sulfamethoxazole given 2-3 times weekly is the drug of choice for the primary prophylaxis of PCP in adults ( A-II: ) and children ( A-I: ) and should be given during the entire period at risk.

The Fifth European Conference on Infections in Leukaemia (ECIL-5) convened a meeting to establish evidence-based recommendations for using tests to diagnose Pneumocystis jirovecii pneumonia (PCP) in adult patients with haematological malignancies. Immunofluorescence assays are recommended as the most sensitive microscopic method (recommendation A-II: ). Real-time PCR is recommended for the routine diagnosis of PCP ( A-II: ).

Background.  Early diagnosis and treatment are crucial in invasive fungal diseases (IFD). Serum (1-3)-β-d-glucan (BG) is believed to be an early IFD marker, but its diagnostic performance has been ambiguous, with insufficient data regarding sensitivity at the time of IFD diagnosis (TOD) and according to outcome.

Pneumocystis jirovecii is an uncultivable fungal pathogen responsible for Pneumocystis pneumonia (PCP) in immunocompromised patients, the physiopathology of which is only partially understood. The diversity of the Pneumocystis strains associated with acute infection has mainly been studied by Sanger sequencing techniques precluding any identification of rare genetic events (< 20% frequency). We used next-generation sequencing to detect minority variants causing infection, and analyzed the complexity of the genomes of infection-causing P.

Incidence of invasive fungal infections increases over time with the rise in at-risk populations; in particular, patients with acquired immunodeficiencies due to immunosuppressive therapies such as anti-tumour necrosis factor-α (TNF-α) treatment, cirrhosis or burns. Some primary immunodeficiencies (PID) can also predispose selectively to invasive fungal diseases. Conversely, some atypical fungal diseases can reveal new PID.

The aim of this study was to assess potential candidate gene regions and corresponding universal primer pairs as secondary DNA barcodes for the fungal kingdom, additional to ITS rDNA as primary barcode. Amplification efficiencies of 14 (partially) universal primer pairs targeting eight genetic markers were tested across > 1 500 species (1 931 strains or specimens) and the outcomes of almost twenty thousand (19 577) polymerase chain reactions were evaluated. We tested several well-known primer pairs that amplify: i) sections of the nuclear ribosomal RNA gene large subunit (D1-D2 domains of 26/28S); ii) the complete internal transcribed spacer region (ITS1/2); iii) partial β -tubulin II (TUB2); iv) γ-actin (ACT); v) translation elongation factor 1-α (TEF1α); and vi) the second largest subunit of RNA-polymerase II (partial RPB2, section 5-6).
