Invasive pulmonary aspergillosis (IPA) is commonly seen in immunocompromised patients, and tracheoesophageal fistula (TEF) induced by IPA is rare and seldom reported. Management of these critically ill patients is challenging and often requires a multidisciplinary approach. The authors reported an adult suffering from aplastic anemia who developed TEF caused by IPA. The diagnosis was confirmed following bronchoscopy and histopathological examination. Antifungal and bronchoscopic intervention provided a cure without any recurrence as yet...

Chronic necrotizing pulmonary aspergillosis (CNPA) is a rare form of pulmonary aspergillosis. The radiological findings in CNPA are very diverse. We present a mildly imunosuppresive, elderly 71-year-old woman with the diagnosis of chronic necrotizing pulmonary aspergillosis presenting as transient migratory thoracic mass.

Allergic bronchopulmonary aspergillosis (ABPA) is a complex pulmonary disorder characterized by recurrent episodes of wheezing, fleeting pulmonary opacities and bronchiectasis. It is the most prevalent of the Aspergillus disorders with an estimated five million cases worldwide. Despite six decades of research, the pathogenesis, diagnosis and treatment of this condition remains controversial. The International Society for Human and Animal Mycology has formed a working group to resolve the controversies around this entity...

INTRODUCTION: Invasive fungal disease (IFD) is an important complication after solid organ transplantation (SOT). A marked geographic variation in the epidemiology of IFD after kidney transplantation (KT) has been suggested by the results of previous studies. Nevertheless, data from Latin American centers are scarce. OBJECTIVE: This study sought to describe the epidemiology of IFD at a Brazilian KT center. METHODS: This study was a retrospective single-center cohort study that included patients who underwent KT between 1998 and 2009 and were followed up until July 2015...

BACKGROUND: Patients treated for hematological malignancies have an increased risk of serious infections. Diagnosis and prompt initiation of therapy are essential. Bronchoalveolar lavage (BAL) is a well-established investigation for identifying the cause of pulmonary infiltrates in immunocompromised patients. The aim of the study was to determine the diagnostic yield of BAL in patients treated for hematological malignancies and how often it contributed to a modification of the anti-infectious therapy...

We describe an interesting case of severe asthma who was not showing satisfactory response to standard treatment. Investigations revealed him to be suffering from allergic bronchopulmonary aspergillosis (ABPA). After starting systemic steroids he showed marked improvement initially only to have recurrent symptoms within a year. He was investigated further and found to have chronic pulmonary aspergillosis in the form of chronic cavitary pulmonary aspergillosis (CCPA) and aspergilloma as also the presence of selective IgA deficiency...

Invasive aspergillosis is predominantly caused by Aspergillus fumigatus and adaptations to stresses experienced within the human host are a prerequisite for the survival and virulence strategies of the pathogen. The central signal transduction pathway operating during hyperosmotic stress is the High Osmolarity Glycerol mitogen-activated protein kinase (MAPK) cascade. A. fumigatus MpkC and SakA, orthologues of the Saccharomyces cerevisiae Hog1p, constitute the primary regulator of the hyperosmotic stress response...

Central nervous system (CNS) aspergillosis is uncommon and considered the most lethal form of aspergillosis. Indeed, current therapeutic strategies such as combination antifungal regimen, neurosurgical resection of infected tissue, and removal of infection source fail to improve the unsatisfactory prognosis of CNS aspergillosis in the majority of the patients. The authors describe a case of chronic pulmonary aspergillosis with concomitant CNS lesions that dramatically responded to antifungal therapy and the CNS lesions resolved in follow-up imaging...

BACKGROUND: Chronic pulmonary aspergillosis (CPA) has substantial impact on quality of life. A subset of patients develops significant pulmonary fibrosis, identified either on biopsy or radiologically. The term chronic fibrosing pulmonary aspergillosis (CFPA) has been suggested. METHODS: We describe 11 patients with CFPA referred to our centre. RESULTS: Mean age was 58.5 years and five were male. In nine, fibrosis was already evident on presentation, while in two it developed 3 and 6 years later...

UNLABELLED: Previous work has shown that environmental and clinical isolates of Aspergillus fumigatus represent a diverse population that occupies a variety of niches, has extensive genetic diversity, and exhibits virulence heterogeneity in a number of animal models of invasive pulmonary aspergillosis (IPA). However, mechanisms explaining differences in virulence among A. fumigatus isolates remain enigmatic. Here, we report a significant difference in virulence of two common lab strains, CEA10 and AF293, in the murine triamcinolone immunosuppression model of IPA, in which we previously identified severe low oxygen microenvironments surrounding fungal lesions...

Culturing strains from clinical samples is the main method to diagnose invasive pulmonary aspergillosis. Detecting the galactomannan antigen in serum samples is an auxiliary examination. The goal of this study was to determine the frequency with which Aspergillus fumigatus was cultured in clinical samples taken from patients hospitalized in the the Infant Jesus Teaching Hospital in Warsaw, Poland, in the period of 2013-2014. Specimens from the respiratory tract and blood were cultured for mycological and serological assessments...

Aspergillus fumigatus causes a range of diseases in human beings, some of which are characterised by fungal persistence. A fumigatus can persist by adapting to the human lung environment through physiological and genomic changes. The physiological changes are based on the large biochemical versatility of the fungus, and the genomic changes are based on the capacity of the fungus to generate genetic diversity by spontaneous mutations or recombination and subsequent selection of the genotypes that are most adapted to the new environment...

We present a case of a patient who following chemotherapy developed semi-invasive pulmonary aspergillosis and an aspergilloma in a lung cavity previously formed by microwave ablation (MWA). A 55-year-old woman presented with cough and shortness of breath after finishing three cycles of chemotherapy for a metastatic nerve sheath tumour. She had been treated by MWA for pulmonary metastases 2 years previously which resulted in a residual right apical lung cavity. Postchemotherapy imaging showed that this cavity had enlarged, developed a thicker wall and contained lobulated soft tissue with a crescent sign on coronal reformats...

Invasive aspergillosis and other fungal infections occur in immunocompromised individuals, including patients who received blood-building stem cell transplants, patients with chronic granulomatous disease (CGD), and others. Production of reactive oxygen species (ROS) by immune cells, which incidentally is defective in CGD patients, is considered to be a fundamental process in inflammation and antifungal immune response. Here we show that the peroxiredoxin Asp f3 of Aspergillus fumigatus inactivates ROS. We report the crystal structure and the catalytic mechanism of Asp f3, a two-cysteine type peroxiredoxin...

BACKGROUND: Spinal artery ischemia is a rare but serious complication of embolization for treatment of hemoptysis. When the spinal artery is visualized at angiography, embolization should not be performed. However, it has been reported that spinal artery feeders are not visible on angiography in patients with developing spinal infarction. CASE REPORT: A 70-year-old man with a history of pulmonary aspergillosis had hemoptysis and underwent contrast-enhanced CT, revealing a pulmonary artery pseudoaneurysm (PAP) in the left upper lobe...
