Invasive pulmonary aspergillosis is an infection seen in patients receiving intensive immunosuppressive regimens, such as transplant recipients. Some risk factors that increase the incidence of infection have been determined, and patients defined as having high risk are recommended to take antifungal prophylaxis and be monitored closely. Here, we present a liver transplant patient with mild respiratory symptoms and a normal chest radiography on day 26 posttransplant. However, he had acute renal failure and underwent hemodialysis, which are both defined to increase significantly the risk of aspergillosis...

Our work aimed to generate a preliminary estimation of severe and chronic fungal diseases in the Republic of Kazakhstan with a model proposed by LIFE (Leading International Fungal Education). Calculations were carried out on data from 2015. Published results of studies of mycoses in Kazakhstan were identified; in the absence of national data from the scientific literature, the frequency of life-threatening and serious mycoses in defined groups of patients at risk from other countries were taken into account...

Introduction: Invasive' pulmonary aspergillosis (IPA) has been one of the major causes of mortality in immunocompromised patients. The gold standard method for a diagnosis of IPA is histopathological examination of the lung tissue; however, post-procedural bleeding limits the feasibility of lung biopsy. The European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and The National Institute of Allergy and Infectious Disease Mycoses Study Group (EORTC/MSG) defined IPA...

The incidence of invasive fungal infections has risen dramatically in the past decades. Current antifungal drugs are either toxic, likely to interact with other drugs, have a narrow spectrum of activity or induce fungal resistance. Hence, there is a great need for new antifungals, possibly with novel mechanisms of action. Previously our group reported an acylhydrazone called BHBM that targeted the sphingolipid pathway, and showed strong antifungal activity against several fungi. In this study, we screened 19 derivatives of BHBM...

The present study investigated the improvement in the diagnosis of invasive pulmonary aspergillosis (IPA) adding a molecular test on bronchoalveolar lavage (BAL) to the routine diagnostic approach including microscopy, culture and galactomannan (GM) immunoassay. A total of 133 BAL samples were retrospectively tested for the Aspergillus DNA: 112 samples were from immunocompromised patients at risk of invasive fungal infection and 21 were from patients not at risk and without clinical evidence of IPA. The latter samples were used to identify the cut-off of positivity for the molecular test...

Invasive pulmonary aspergillosis (IPA) is a common complication of immunosuppression. Rapid diagnosis using molecular techniques is essential to improve patient survival. PCR techniques are promising in enhancing Aspergillus detection in blood and respiratory samples. Here, we evaluate for the first time the performances of two commercial Real-Time PCR kits, the A. fumigatus® Bio-Evolution and the MycoGENIE® A. fumigatus for the detection of A. fumigatus DNA in broncho-alveolar lavage (BAL) from patients with and without IPA...

The newly developed AspID PCR assay for detection of Aspergillus spp. was evaluated with an interlaboratory quality control program panel and human bronchoalveolar lavage fluid (BALF) samples. With the quality control program, eight out of nine panel members were correctly identified. With the clinical study, 36 BALF samples that had been obtained from 18 patients with invasive pulmonary aspergillosis (IPA) and 18 without IPA were investigated. Sensitivity, specificity, positive and negative likelihood ratio for the AspID assay were 94...

Invasive pulmonary aspergillosis (IPA) is classically considered an illness of severely immunocompromised patients with limited host defenses. However, IPA has been reported in immunocompetent but critically ill patients. This report describes two fatal cases of pathologically confirmed IPA in patients with influenza in the intensive care unit. One patient had influenza B infection, whereas the other had influenza A H1N1. Both patients died despite broad-spectrum antimicrobials, mechanical ventilation, and vasopressor support...

Aspergillus fumigatus is an opportunistic pathogen, the leading cause of invasive and disseminated aspergillosis in systemic immunocompromised patients, and an important cause of mortality. The aim of the present study was to adapt a pulmonary aspergillosis murine model, to determine pathodynamical parameters quantitatively, and to follow the progression of fungal infection in vivo. The nasal inoculation of Aspergillus conidia in mice previously subjected to immunosuppression with cyclophosphamide (CP) turned out to be a more suitable model than that of immunosuppressed with hydrocortisone (HC)...

Non-fumigatus Aspergillus species are the leading cause of Aspergillus infections in the tropical and subtropical regions of the world. In a prospective study between 2015 and 2016, a total of 150 bronchoalveolar (BAL) specimens was collected from patients suspected to pulmonary aspergillosis (PA) underlying immunodeficiencies in Mashhad, Northeastern Iran, located in the Middle East. All Aspergillus strains were phylogenetically identified at the species level by PCR-sequencing of partial β-tubulin gene. Overall, Aspergillus species were isolated from 20 specimens originating from 10 (50%) patients with cancer, 5 (25%) patients receiving corticosteroid therapy, 3 (15%) organ transplant recipients and 2 (10%) patients admitted to intensive care unit (ICU)...

A 67-year old man visited our hospital with complaints of fever and cough. He had a past medical history of renal cell carcinoma and had just started treatment with temsirolimus, a mammalian target of rapamycin (mTOR) inhibitor. A 1-week course of antibiotics did not have any effect on his symptoms. Chest computed tomography (CT) scan showed reversed halo sign (RHS). Organizing pneumonia induced by mTOR inhibitor treatment was initially considered. However, transbronchial biopsy revealed clusters of fungal organisms, suggesting infection with Aspergillus spp...

INTRODUCTION: Few studies have assessed the efficacy and safety of micafungin in patients with proven or probable invasive aspergillosis (IA). This was the aim of the current study, which was conducted in 22 hospitals in China, where micafungin was approved for treatment of IA in 2006. METHODS: This was a non-comparative, phase IV open-label study (NCT02646774). Eligible patient were adults with proven or probable IA. Efficacy endpoints included rates of overall treatment success (primary endpoint) and clinical improvement, fungal clearance, mortality, and the site of Aspergillus infection (all secondary endpoints)...
