Multilocus sequence typing analysis reveals that Cryptococcus neoformans var. neoformans is a recombinant population.

Cryptococcus neoformans var. neoformans (serotype D) represents about 30% of the clinical isolates in Europe and is present less frequently in the other continents. It is the prevalent etiological agent in primary cutaneous cryptococcosis as well as in cryptococcal skin lesions of disseminated cryptococcosis.

Early diagnosis and monitoring of mucormycosis by detection of circulating DNA in serum: retrospective analysis of 44 cases collected through the French Surveillance Network of Invasive Fungal Infections (RESSIF).

The main objective of this study was to assess the diagnostic performance of a set of three Mucorales quantitative PCR assays in a retrospective multicentre study. Mucormycosis cases were recorded thanks to the French prospective surveillance programme (RESSIF network). The day of sampling of the first histological or mycological positive specimen was defined as day 0 (D0).

Isavuconazole versus voriconazole for primary treatment of invasive mould disease caused by Aspergillus and other filamentous fungi (SECURE): a phase 3, randomised-controlled, non-inferiority trial.

Background: Isavuconazole is a novel triazole with broad-spectrum antifungal activity. The SECURE trial assessed efficacy and safety of isavuconazole versus voriconazole in patients with invasive mould disease.

Methods: This was a phase 3, double-blind, global multicentre, comparative-group study.

[Cryptococcus where they are not expected: Five case reports of extra-cerebral and extra-pulmonary cryptococcosis].

Cryptococcosis is a serious infection, possibly lethal, of worldwide distribution. It mainly affects immunosuppressed patients resulting with pulmonary and/or meningeal involvements or disseminated infections. Due to the rarity of visceral and osseous infections, and to the absence of specific clinical symptoms, this diagnosis is often deferred.

Typing Candida Species Using Microsatellite Length Polymorphism and Multilocus Sequence Typing.

To gain more insight into the epidemiological relationships between isolates of Candida spp. obtained from various origins, several molecular typing techniques have been developed. Two methods have emerged in the 2000s as soon as enough knowledge of the Candida spp.

Opportunistic infections and biologic therapies in immune-mediated inflammatory diseases: consensus recommendations for infection reporting during clinical trials and postmarketing surveillance.

No consensus has previously been formed regarding the types and presentations of infectious pathogens to be considered as 'opportunistic infections' (OIs) within the setting of biologic therapy. We systematically reviewed published literature reporting OIs in the setting of biologic therapy for inflammatory diseases. The review sought to describe the OI definitions used within these studies and the types of OIs reported.

Prospective pilot study of high-dose (10 mg/kg/day) liposomal amphotericin B (L-AMB) for the initial treatment of mucormycosis.

Background: Mucormycosis incidence is increasing and is associated with a high rate of mortality. Although lipid-based formulations of amphotericin B are the recommended first-line treatment, only one prospective trial in a limited number of patients has been performed to evaluate this regimen.

Methods: Patients with proven or probable mucormycosis were included between June 2007 and March 2011.

Relevance of EORTC Criteria for the Diagnosis of Invasive Aspergillosis in HIV-Infected Patients, and Survival Trends Over a 20-Year Period in France.

Background: Before the advent of combination antiretroviral therapy (cART), roughly 50% of cases of invasive aspergillosis (IA) associated with human immunodeficiency virus (HIV) infection involved individuals without classical predisposing host factors, and the median survival time was <4 months after diagnosis. We examined if the situation evolved over time using the revised European Organisation for Research and Treatment of Cancer/National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC) definition and analyzed survival trends after diagnosis over 20 years.

Methods: A data review committee evaluated 342 medical records that mentioned IA in the French Hospital Database on HIV.

New Short Tandem Repeat-Based Molecular Typing Method for Pneumocystis jirovecii Reveals Intrahospital Transmission between Patients from Different Wards.

Pneumocystis pneumonia is a severe opportunistic infection in immunocompromised patients caused by the unusual fungus Pneumocystis jirovecii. Transmission is airborne, with both immunocompromised and immunocompetent individuals acting as a reservoir for the fungus. Numerous reports of outbreaks in renal transplant units demonstrate the need for valid genotyping methods to detect transmission of a given genotype.

Dual Invasive Infection with Phaeoacremonium parasiticum and Paraconiothyrium cyclothyrioides in a Renal Transplant Recipient: Case Report and Comprehensive Review of the Literature of Phaeoacremonium Phaeohyphomycosis.

Despite increasing reports of human infection, data about the optimal care of Phaeoacremonium infections are missing. We report a case of an infection due to Phaeoacremonium parasiticum and Paraconiothyrium cyclothyrioides, initially localized to skin and soft tissue, in a kidney transplant patient. Despite surgical drainage and excision of the lesion and combination antifungal therapy with voriconazole and liposomal amphotericin B, a disseminated infection involving the lungs and brain developed and led to death.

Importance of operational factors in the reproducibility of Aspergillus galactomannan enzyme immune assay.

Background: The Platelia Aspergillus Ag assay (Bio-Rad) is designed for detecting Aspergillus galactomannan (GM) and is widely used for diagnosing invasive aspergillosis but is hampered by variable occurrences of unreproducible positive results. Frequency and origin of these unreproducible results have not been formally studied.

Methods: Different technicians simultaneously performed four tests on 550 consecutive sera from adult patients (Test#1-Test#2 for extraction#1 and Test#3-Test#4 for extraction#2).

Molecular identification of Mucorales in human tissues: contribution of PCR electrospray-ionization mass spectrometry.

Molecular methods are crucial for mucormycosis diagnosis because cultures are frequently negative, even if microscopy suggests the presence of hyphae in tissues. We assessed PCR/electrospray-ionization mass spectrometry (PCR/ESI-MS) for Mucorales identification in 19 unfixed tissue samples from 13 patients with proven or probable mucormycosis and compared the results with culture, quantitative real-time PCR, 16S-23S rRNA gene internal transcribed spacer region (ITS PCR) and 18S PCR sequencing. Concordance with culture identification to both genus and species levels was higher for PCR/ESI-MS than for the other techniques.

Utility of adding Pneumocystis jirovecii DNA detection in nasopharyngeal aspirates in immunocompromised adult patients with febrile pneumonia.

Detection of viral and bacterial DNA in nasopharyngeal aspirates (NPAs) is now a routine practice in emergency cases of febrile pneumonia. We investigated whether Pneumocystis jirovecii DNA could also be detected in these cases by conducting retrospective screening of 324 consecutive NPAs from 324 adult patients (198 or 61% were immunocompromised) admitted with suspected pulmonary infections during the 2012 influenza epidemic season, using a real-time quantitative polymerase chain reaction (PCR) assay (PjqPCR), which targets the P. jirovecii mitochondrial large subunit ribosomal RNA gene.

Lack of 1-3-B-D-glucan detection in adults with bacteraemia.

Bacteraemia was reported to be associated with false-positive 1→3-β-D-glucan (BG) assay results. We thus prospectively assessed the reactivity of the BG (Fungitell) in samples of 21 adults with bacteraemia: . BG was negative in all and is s therefore an unlikely cause of false positive BG in adults.

Imported pythium insidiosum keratitis after a swim in Thailand by a contact lens-wearing traveler.

A 30-year-old woman with a history of contact lens wear and exposure to swimming pool water in Thailand presented with a non-responsive, progressive corneal ulcer of the right eye. Confocal microscopy evidenced septate linear branching structures, raising suspicion of fungal keratitis. She was promptly treated with topical antibiotics and both topical and intravenous caspofungin plus voriconazole.

Invasive mold infections in solid organ transplant recipients.

Invasive mold infections represent an increasing source of morbidity and mortality in solid organ transplant recipients. Whereas there is a large literature regarding invasive molds infections in hematopoietic stem cell transplants, data in solid organ transplants are scarcer. In this comprehensive review, we focused on invasive mold infection in the specific population of solid organ transplant.

Posttraumatic mucormycosis: a nationwide study in France and review of the literature.

Data on clinical, mycologic characteristics, and outcome of posttraumatic mucormycosis are scarce and often limited to case reports. From the French nationwide "RetroZygo" study, we compared posttraumatic mucormycosis cases with other forms of mucormycosis. We also reviewed reports of posttraumatic mucormycosis in the English-language literature from 1993 to 2013.

Last generation triazoles for imported eumycetoma in eleven consecutive adults.

Background: Optimal management of eumycetoma, a severely debilitating chronic progressive fungal infection of skin, disseminating to bone and viscera, remains challenging. Especially, optimal antifungal treatment and duration are ill defined.

Methodology/principal Findings: We conducted a monocentric retrospective study of 11 imported cases of eumycetoma treated by voriconazole or posaconazole for at least 6 months.

Mucormycosis: a new concern in the transplant ward?

Purpose Of Review: This study focuses on the epidemiology and management of mucormycosis in hematopoietic stem cell transplant patients, a life-threatening mold infection whose incidence has increased over the past decades.

Recent Findings: Mucormycosis may occur in hematopoietic stem cell transplant recipients with severe graft-versus-host disease, steroids, neutropenia, iron overload, diabetes, and malnutrition, or those who received antifungals not active against Mucorales. Its incidence in allogeneic hematopoietic stem cell transplant is around 0.

Imported African histoplasmosis in an immunocompetent patient 40 years after staying in a disease-endemic area.

Histoplasmosis caused by Histoplasma capsulatum var. duboisii is a rare disease outside central and western Africa. In Europe, all cases are imported.

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.

Very prolonged liposomal amphotericin B use leading to a lysosomal storage disease.

Amphotericin B is a powerful polyene antifungal drug used for treating systemic fungal infections and is usually administered for a short period. Side effects after prolonged use are unknown in humans. Here we report the case of a 28-year-old man suffering from chronic granulomatous disease (CGD), treated for invasive cerebral aspergillosis with liposomal amphotericin B (L-AmB) for a very long time (8 consecutive years).

Critical importance of long-term adherence to care in HIV infected patients in the cART era: new insights from Pneumocystis jirovecii pneumonia cases over 2004-2011 in the FHDH-ANRS CO4 cohort.

Objective: To describe characteristics and outcomes of HIV-infected patients with Pneumocystis jirovecii pneumonia (PCP) over 2004-2011 in France, in particular in those previously enrolled (PE) in the French Hospital Database on HIV (FHDH).

Methods: PE patients with an incident PCP were compared with patients with an inaugural PCP revealing HIV infection (reference). Adequate adherence to care was defined as a CD4 measurement at least every 6 months.
