BACKGROUND: Accurate diagnosis of invasive mold diseases (IMD) remains challenging. Here, the performance of panfungal PCR, Aspergillus and Mucorales PCR in bronchoalveolar lavage (BAL) was evaluated. METHODS: We conducted a single-center study including 167 hematologic patients at risk for IMD with BAL performed 2011-2014. Diagnostic performance of single tests (Aspergillus-, Mucorales-and panfungal PCR, galactomannan (GM)≥0.5 and ≥1, culture/cytology) or in combination was calculated for predicting IMD comparing proven/probable or proven/probable/possible IMD versus no IMD, respectively...

Severely immunocompromised patients are at increased risk for uncommon infectious diseases with atypical presentations. Fusarium sp., has been reported in patients with hematological malignancies and prompt diagnosis is necessary due to high mortality. We report a myelodysplastic syndrome (MDS) patient who presented Fusarium solani infection associated with granulocytic sarcoma as an initial presentation of acute myeloid leukemia (AML) transformation. We performed histological examination, immunohistochemistry analysis, culture of the biopsy tissue and DNA sequencing to make a conclusive diagnosis of F...

Background : Deoxynivalenol (DON) and zearalenone (ZEN) are common food contaminants produced by Fusarium sp. Mycotoxins are a potential health hazard because of their toxicological effects on both humans and farmed animals. Methods: We analyzed three groups of pigs: a control group (fed a standard diet), and the DON and ZEN groups, fed a diet containing 8 mg/kg DON and 0.8 mg/kg ZEN respectively, for four weeks. Results : DON and ZEN exposure decreased body weight (BW), average daily feed intake (ADFI), food conversion rate (FCR), and the serum levels of immunoglobulin (Ig)G and IgM...

Deoxynivalenol (DON) is a toxic fungal secondary metabolite produced by molds of the Fusarium genus, and it is known to cause a spectrum of diseases both in humans and animals, such as emesis, diarrhea, anorexia, immunotoxicity, hematological disorders, impairment of maternal reproduction, and fetal development. The recently revealed teratogenic potential of DON has received much attention. In various animal models, it has been shown that DON led to skeletal deformities of the fetus. However, the underlying mechanisms are not yet fully understood, and toxicological data are also scarce...

Fusarium infection is a severe fungal infection caused by fungi of the genus Fusarium. It most commonly occurs in immunocompromised patients with malignant hematological comorbidities or secondary to hematopoietic stem cell transplant. The classical route of contamination is through inhalation but infection may also occur through contiguity with a skin lesion. This report describes the case of a 24-year-old woman who developed graft-vs.-host disease (GVHD) at 220 days after receiving an allogeneic stem cell transplant from a sibling donor for Hodgkin disease...

Over the last few decades, the number of patients susceptible to invasive filamentous fungal infections has steadily increased, especially in populations suffering from hematological diseases. The pathogens responsible for such mycoses are now quite well characterized, such as Aspergillus spp. - the most commonly isolated mold -, Mucorales, Fusarium spp., Scedosporium spp. or melanized fungi. An increase in the incidence of this category of 'emerging' fungi has been recently highlighted, evoking a shift in fungal ecology...

Invasive fungal disease (IFD) has high mortality rate, especially in the growing population of immunocompromised patients. In spite of introduction of novel diagnostic approaches, the intravital recognition of IFD is challenging. Autopsy studies remain a key tool for assessment of epidemiology of visceral mycoses. We aimed to determine species distribution and trends of IFD over the last 10 years in unselected autopsy series from a large university hospital. Forty-five cases of visceral mycoses, confirmed by histopathology and panfungal PCR, were found in 587 consecutive autopsies...

BACKGROUND AIMS: Invasive fungal diseases caused by filamentous fungi and yeasts are significant causes of morbidity and mortality in immunosuppressed hematology patients. We previously published a method to expand Aspergillus fumigatus-specific T cells for clinical cell therapy. In the present study, we investigated expansion of T cells specific for other fungal pathogens and creation of a broadly reactive panfungal T-cell product. METHODS: Fungal strains selected were those frequently observed in the clinical hematology setting and included Aspergillus, Candida, Fusarium, Rhizopus and Lomentospora/Scedosporium...

BACKGROUND: Invasive fusariosis is an infection with Fusarium spp. that primarily affects patients with hematologic malignancies and hematopoietic cell transplant recipients. Wounds, digital ulcers, onychomycosis, and paronychia are the typical cutaneous portals of entry. Early management of mycotic nails in immunocompromised and diabetic hosts is crucial to prevent life-threatening disease. OBJECTIVES: We report nine cases of Fusarium onychomycosis (F. dimerum, n = 5; F...

Mould species represent the pathogens most commonly associated with invasive fungal disease in patients with haematological malignancies and patients of haemopoietic stem cell transplants. Invasive mould infections in these patient populations, particularly in the setting of neutropenia, are associated with high morbidity and mortality, and significantly increase the complexity of management. While Aspergillus species remain the most prevalent cause of invasive mould infections, Scedosporium and Fusarium species and the Mucormycetes continue to place a significant burden on the immunocompromised host...

Fusarium is a filamentous opportunistic pathogenic fungus responsible for superficial as well as invasive infection in immunocompromized hosts. Net state of immunosuppression and cytomegalovirus (CMV) infection appear to predispose to this disease which is life-threatening when disseminated. Though infections with Fusarium have been widely described in hematological malignancies and hematopoietic stem cell transplant cases, they have been reported to be rare in solid organ transplant recipients, are often localized and carry a favorable prognosis...

Invasive fungal infections are important causes of morbidity and attributable mortality in neutropenic patients with hematological malignancies, myelodysplasia, and aplastic anemia. Successful risk-based strategies can be implemented for prophylaxis, empirical therapy, and preemptive therapy for the prevention and early treatment of invasive fungal infections in neutropenic hosts. The use of echinocandins for invasive candidiasis and voriconazole for invasive aspergillosis has significantly improved outcome...

The frequency of breakthrough invasive fungal diseases (IFDs) during echinocandin therapy is unclear. We retrospectively analyzed 534 hematologic patients treated with echinocandin (caspofungin, N = 55; micafungin, N = 306; anidulafungin, N = 173). Four proven IFDs were found, caused by Candida parapsilosis (N = 2), C. parapsilosis and Candida glabrata (N = 1), and Fusarium species (N = 1). Four cases of possible IFDs were observed, all showing pulmonary infection. One case showed features suggestive of hepatosplenic candidiasis...

Mycotoxin mitigation is of major interest as ingestion of mycotoxins results in poor animal health, decreased productivity, as well as substantial economic losses. A feed additive (FA) consisting of a combination of bacteria (Eubacterium BBSH797) and enzyme (fumonisin esterase FumD) was tested in pigs for its ability to neutralize the effects of mono- and co-contaminated diets with deoxynivalenol (DON) and fumonisins (FB) on hematology, biochemistry, tissue morphology, and immune response. Forty-eight animals, allocated into eight groups, received one of eight diets for 35 days: a control diet, a diet contaminated with either DON (3 mg/kg) or FB (6 mg/kg), or both toxins, and the same four diets with FA...
