Aspergillus spp are ubiquitous in the environment, and inhalation of Aspergillus spores is unavoidable. An intact immune system, with normal airway function, protects most people from disease. Globally, however, the toll from aspergillosis is high. The literature has largely focused on invasive aspergillosis, yet the burden in terms of chronicity and prevalence is higher for noninvasive Aspergillus conditions. This article discusses allergic aspergilloses and provides an update on the diagnosis and management of allergic bronchopulmonary aspergillosis, including in patients with cystic fibrosis, and an update on severe asthma with fungal sensitization...

BACKGROUND: Extracorporeal membrane oxygenation is an established life-saving procedure for severe acute respiratory failure due to various causes. In general, the duration of extracorporeal membrane oxygenation ranges from 1 to 2 weeks, with withdrawal recommended if no improvement is noted. We report a successful case of long-term extracorporeal membrane oxygenation management for respiratory failure due to invasive pulmonary Aspergillus infection. CASE PRESENTATION: A 64-year-old Asian man with no previous underlying medical conditions was transferred to our hospital for fever and dyspnea...

WHAT IS KNOWN AND OBJECTIVE: Voriconazole and vincristine are major therapeutics in paediatric haematology. However, the risk-benefit ratio of the treatment of invasive aspergillosis with voriconazole in patients receiving vincristine-based chemotherapy remains unclear. CASE DESCRIPTION: We report severe peripheral and central neurological disorders in a 14-year-old girl with T-cell acute lymphoblastic leukaemia and pulmonary aspergillosis. The case describes a strong exacerbation by voriconazole of the vincristine-induced neuropathic pains...

Von Willebrand factor (VWF) is secreted as an acute phase protein during inflammation. ADAMTS-13 regulates the size and prothrombotic activity of VWF by it's specific proteolytic activity. To determine the relevance of this regulatory pathway for the innate inflammatory response by polymorphonuclear neutrophils (PMN), we employed a mouse model of invasive pulmonary aspergillosis (IPA) where PMN functionality is crucial for fungal clearance and survival. IPA was induced by intratracheal application of Aspergillus fumigatus (A...

Critically ill patients and patients with haematological cancer are HIV-negative populations at high risk of invasive fungal infections. In intensive-care units, candidaemia and intra-abdominal candidiasis predominate, but aspergillosis has emerged as a lethal, under-recognised cause of pneumonia. In patients with haematological malignancies or who have undergone stem-cell transplantations, pulmonary disease due to aspergillus and other mould diseases predominate. In this Series paper, we provide an update on risk assessment, new diagnostic strategies, and therapeutic approaches...

Metal restriction imposed by mammalian hosts during an infection is a common mechanism of defense to reduce or avoid the pathogen infection. Metals are essential for organism survival due to its involvement in several biological processes. Aspergillus fumigatus causes invasive aspergillosis (IA), a disease that typically manifests in immunocompromised patients. A. fumigatus PpzA, the catalytic subunit of protein phosphatase Z (PPZ), has been recently identified as associated with iron assimilation. A. fumigatus has two high affinity mechanisms of iron acquisition during infection: reductive iron assimilation (RIA) and siderophore-mediated iron uptake...

Caspofungin (CAS) which is used as salvage therapy in patients with invasive pulmonary aspergillosis (IPA) inhibits the 1,3-β-D-glucan synthesis in Aspergillus fumigatus. Inhibiting 1,3-β-D-glucan synthesis induces a stress response and in an invertebrate model it was demonstrated that inhibiting this response with geldamycin enhanced the therapeutic efficacy of CAS. Since geldamycin itself is toxic to mammalians, the therapeutic efficacy of combining geldamycin with CAS was not studied in rodent models. Therefore in this study we investigated if the geldamycin derivate 17-(allylamino)-17-demethoxygeldanamycin (17-AAG) was able to enhance the therapeutic efficacy of CAS in vitro and in our IPA model in transiently neutropenic rats...

Combining voriconazole and flucloxacillin is indicated in patient cohorts experiencing both invasive aspergillosis and gram-positive infections (e.g. patients with chronic granulomatous disease or post-influenza pulmonary aspergillosis). We report a highly relevant interaction between voriconazole and flucloxacillin resulting in subtherapeutic voriconazole plasma concentrations in more than 50% of patients, posing a severe threat if not managed properly.

BACKGROUND: The sensitivity of galactomannan (GM) assay is suboptimal for detecting invasive pulmonary aspergillosis (IPA) in serum samples. However, the clinical characteristics, radiologic findings, and outcomes in patients with GM-negative IPA have not been fully elucidated. METHODS: Over a 7-year period, adult patients with proven or probable IPA by the EORTC/MSG definition were retrospectively enrolled. Patients with negative GM results and positive Aspergillus spp...

Aspergillus is described as mould characterised by septate hyphae about 2-4μ in diameter, it is ubiquitous in nature and spreads by inhalation of spores. It causes opportunistic infections in almost six forms namely Allergic bronchopulmonary aspergillosis, Aspergillus sinusitis, Cutaneous aspergillosis, Aspergilloma, Chronic pulmonary aspergillosis, Invasive aspergillosis. Invasive aspergillosis of mediastinum in an immunocompetent patient has rarely been reported. We present a case of a young male who had presented with chest pain, cough and breathleness was later diagnosed as fulminant mediastinal aspergillosis...

Invasive pulmonary aspergillosis (IPA) is an important cause of morbidity and mortality in immunocompromised patients. We hypothesized that simultaneous inhibition of biosynthesis of ergosterol in the fungal cell membrane and (1→3)-β-D-glucan in the cell wall, respectively, by the antifungal triazole isavuconazole and the echinocandin micafungin, may result in improved outcome in experimental IPA in persistently neutropenic rabbits. Treatment groups included isavuconazole (ISA) at 20 (ISA20), 40 (ISA40), and 60 (ISA60) mg/kg/day, micafungin at 2 mg/kg/day (MFG2), or combinations of (ISA20+MFG2), (ISA40+MFG2), (ISA60+MFG2), and untreated rabbits (UC)...

The number of patients with hematological malignancies who develop invasive fungal disease (IFD) has increased dramatically in recent decades. This increase is attributed to impairment of the host immune system due to intensive cytotoxic chemotherapies, use of corticosteroids and profound immunosuppression after hematopoietic stem cell transplantation (HSCT). Additionally, the increasing prevalence of fungal infections caused by emerging and rare pathogens, IFD of mixed etiology or of atypical localization is observed...

Invasive aspergillosis generally occurs during the first 1-6 months after heart transplantation. It has been rarely seen in the first 2 weeks postcardiac transplant. We herein describe a unique case of invasive pulmonary aspergillosis (IPA) diagnosed on day 9 postorthotopic heart transplantation. The known risk factors for IPA in cardiac transplant recipients were not identified in our case. The organ recipients from the same donor did not report Aspergillus infection. Hospital environmental samplings failed to demonstrate Aspergillus spores in the patient's room and his adjacent rooms...

BACKGROUND: Invasive pulmonary aspergillosis (IPA) is an increasingly recognized problem in critically ill patients. Little is known about how intensivists react to a Aspergillus-positive respiratory sample and about the efficacy of antifungals. Our goal was to identify drivers of antifungal therapy (AFT) prescription and diagnostic workup in patients with Aspergillus isolation in respiratory specimens as well as the impact of AFT in these patients. METHODS: ICU patients with a Aspergillus-positive respiratory sample from the database of a previous observational multicenter study were analysed...

Invasive pulmonary aspergillosis (IPA) is one of the major complications in immunocompromised patients. The mainstay of diagnostic imaging is non-enhanced chest-computed-tomography (CT), for which various non-specific signs for IPA have been described. However, contrast-enhanced CT pulmonary angiography (CTPA) has shown promising results, as the vessel occlusion sign (VOS) seems to be more sensitive and specific for IPA in hematologic patients. The aim of this study was to evaluate the diagnostic accuracy of CTPA in a larger cohort including non-hematologic immunocompromised patients...

OBJECTIVES: To assess the risk factors for the development of late-onset invasive pulmonary aspergillosis (IPA) after kidney transplantation (KT). METHODS: We performed a multinational case-control study that retrospectively recruited 112 KT recipients diagnosed with IPA between 2000 and 2013. Controls were matched (1:1 ratio) by center and date of transplantation. Immunosuppression-related events (IREs) included the occurrence of non-ventilator-associated pneumonia, tuberculosis, cytomegalovirus disease and/or de novo malignancy...
