Echinococcosis is a zoonotic disease caused by Echinococcus granulosus sensu lato. The liver and lungs are the most commonly sites of infections, but involvements of other organs were also observed. Recently, the coinfection of pulmonary hydatid cyst with aspergilloma has been reported in the literature. Herein, we report a successful treatment of coinfection of cystic echinoccosis with aspergilloma due to Aspergillus flavus in a 34-year-old female. In vitro antifungal susceptibility tests revealed that the MIC values for antifungals employed in this case were posaconazole (0...

Volatile organic compounds (VOCs) in exhaled breath may identify the presence of invasive pulmonary aspergillosis. We aimed to detect VOC profiles emitted by in vitro cultured, clinical Aspergillus isolates using gas chromatography-mass spectrometry (GC-MS). Three clinical Aspergillus isolates and a reference strain were cultured while conidiation was prevented. Headspace samples were analyzed using a standardized method. Breath samples of patients from which the cultures were obtained were checked for the presence of the VOCs found in vitro...

Bronchiectasis is a chronic irreversible airway abnormality associated with infectious agents that either cause or superinfect the airways. While the role of bacteria is well studied, much remains to be determined about fungi in both cystic fibrosis- and non-cystic fibrosis-related bronchiectasis. The airway is constantly exposed to inhaled ambient moulds of which Aspergillus represent the most ubiquitous. In a normal healthy host, this situation is of little consequence. The presence of anatomical or immunological abnormalities such as those in bronchiectasis leads to a range of fungal-related pathologies from asymptomatic airway colonization to fungal sensitization, allergic bronchopulmonary aspergillosis or chronic pulmonary aspergillosis...

We describe the first rescue procedure in a case of total face allotransplantation. The recipient was a 54-year-old man with severe disfigurement of the entire face following an accidental gunshot injury 5 years previously. The large defect included the maxilla, mandible, and mid-face. Full face procurement was performed from a multiorgan cadaveric donor and was allotransplanted to the recipient. The post-transplant induction immunosuppressive regimen included ATG combined with tacrolimus, mycophenolate mofetil, and prednisone, while maintenance was provided by the last three of these...

BACKGROUND: Invasive aspergillosis is the most common invasive fungal infection in lung transplant recipients. The use of galactomannan testing in bronchoalveolar lavage (BAL) fluid has improved diagnosis of invasive aspergillosis; however, false-positive results can lead to overdiagnosis and unnecessary treatment. The use of proinflammatory markers such as pentraxin 3 (PTX3) may help differentiate between Aspergillus colonization and disease. METHODS: BAL PTX3 concentrations were measured by enzyme-linked immunosorbent assay in 151 lung transplant recipients and 9 healthy control subjects...

BACKGROUND: Triggering receptor expressed on myeloid cell-1 (TREM-1) may play a vital role in mammalian target of rapamycin (mTOR) modulation of CD8+ T-cell differentiation through the transcription factors T-box expressed in T-cells and eomesodermin during the immune response to invasive pulmonary aspergillosis (IPA). This study aimed to investigate whether the mTOR signaling pathway modulates the proliferation and differentiation of CD8+ T-cells during the immune response to IPA and the role TREM-1 plays in this process...

A 67-year-old female with rheumatoid arthritis and asthma-chronic obstructive pulmonary disease overlap syndrome was admitted for drug-induced hypersensitivity syndrome (DIHS) caused by salazosulfapyridine. Human herpes virus 6 (HHV-6) variant B was strongly positive on peripheral blood. Multiple cavities with ground grass opacities rapidly emerged predominantly in the upper and middle lobes. She was diagnosed with invasive pulmonary aspergillosis (IPA), and was treated successfully with antifungal agents. Therapeutic systemic corticosteroids, emphysematous change in the lungs, and the worsening of the patient's general condition due to DIHS were considered major contributing factor leading to IPA...

Allergic bronchopulmonary aspergillosis (ABPA) is a pulmonary disorder that often occurs in patients with asthma or cystic fibrosis (CF) and is characterized by a hypersensitivity response to the allergens of the fungus Aspergillus fumigatus. In patients with CF, growth of A. fumigatus hyphae within the bronchial lumen triggers an immunoglobulin E (IgE)-mediated hypersensitivity response that results in airway inflammation, bronchospasm, and bronchiectasis. In most published studies, the prevalence of ABPA is about 8...

Invasive pulmonary aspergillosis (IPA) is an infection that often occurs in immunocompromised patients and has a high mortality rate. In recent years, the reported incidence of IPA in the context of chronic obstructive pulmonary disease (COPD) has seemingly increased. The combination of factors such as long-term corticosteroid use, increasing rate of bacterial exacerbations over time, lung immune imbalance, and malnutrition are responsible for the emergence of IPA in COPD patients. A diagnosis of IPA in COPD patients is difficult to make, which explains the delay in antifungal therapy and the high mortality rate...

Trehalose biosynthesis is found in fungi but not humans. Proteins involved in trehalose biosynthesis are essential for fungal pathogen virulence in humans and plants through multiple mechanisms. Loss of canonical trehalose biosynthesis genes in the human pathogen Aspergillus fumigatus significantly alters cell wall structure and integrity, though the mechanistic link between these virulence-associated pathways remains enigmatic. Here we characterize genes, called tslA and tslB, which encode proteins that contain domains similar to those corresponding to trehalose-6-phosphate phosphatase but lack critical catalytic residues for phosphatase activity...

Aspergillus fumigatus (A. fumigatus) is one of the most common fungal pathogens of invasive pulmonary aspergillosis (IPA), which may be life threatening in immunocompromised individuals. The dendritic cell-associated C-type lectin receptor (Dectin-1), toll‑like receptor (TLR)-2 and TLR-4 are major pattern recognition receptors in alveolar macrophages that recognize A. fumigatus components. The PU.1 transcription factor is known to be important for the transcriptional control of these three receptors in mature macrophages...

Clinical experience has shown that allergic and non-allergic respiratory, metabolic, mental, and cardiovascular disorders sometimes coexist with bronchial asthma. However, no study has been carried out that calculates the chance of manifestation of these disorders with bronchial asthma in Saarland and Rhineland-Palatinate, Germany. Using ICD10 diagnoses from health care institutions, the present study systematically analyzed the co-prevalence and odds ratios of comorbidities in the asthma population in Germany...

BACKGROUND: Pulmonary infection is the main cause of death in cystic fibrosis (CF). Aspergillus fumigatus (AF) and Pseudomonas aeruginosa (PA) are the most prevalent fungal and bacterial pathogens isolated from the CF airway, respectively. Our aim was to determine the effect of different colonisation profiles of AF and PA on the clinical status of patients with CF. METHODS: A retrospective analysis of data from the Cystic Fibrosis Registry of Ireland from 2013 was performed to determine the effect of intermittent and persistent colonisation with AF or PA or co-colonisation with both microorganisms on clinical outcome measures in patients with CF...

Chronic necrotizing pulmonary aspergillosis (CNPA), a form of chronic pulmonary aspergillosis (CPA), affects immunocompetent or mildly immunocompromised persons with underlying pulmonary disease. These conditions are associated with high morbidity and mortality and often require long-term antifungal treatment. The long-term prognosis for patients with CNPA and the potential complications of CNPA have not been well documented. The aim of this study was to review published papers that report cases of CNPA complications and to highlight risk factors for development of CNPA...
