To identify potential risk factors for lung disease progression in children with cystic fibrosis (CF), we studied the longitudinal data of all children with CF (aged ≥5 years) registered in the Dutch CF Registry (2009-2014). Lung disease progression was expressed as a decline in lung function (FEV1 %pred) and the pulmonary exacerbation rate (PEx). Potential risk factors at baseline included: sex, age, best FEV1%pred, best forced vital capacity (FVC)%pred, genotype, BMI z-score, pancreatic insufficiency, medication use (proton pump inhibitors [PPI], prophylactic antibiotics, and inhaled corticosteroids), CF-related diabetes, allergic bronchopulmonary aspergillosis, and colonisation with Pseudomonas aeruginosa The data of 545 children were analysed...

BACKGROUND: Several serological tests for specific precipitin or IgG are available to demonstrate type III hypersensitivity reactions to Aspergillus species and are essential for infectious fungal disease diagnosis. These assays are also important for allergic bronchopulmonary aspergillosis (ABPA) diagnosis; however, their concordance in ABPA was not well studied. METHODS: Fifty-two ABPA patients diagnosed based on ISHAM criteria were enrolled. Precipitins and IgG specific to Aspergillusfumigatus, Aspergillusniger, Aspergillusflavus, or Aspergillusterreus were measured using Ouchterlony double immunodiffusion tests and ImmunoCAP method, respectively...

BACKGROUND: Pulmonary non-tuberculous mycobacterial disease (PNTM) is a known risk factor for chronic pulmonary aspergillosis (CPA). However, few studies have focused on the prognosis of PNTM-associated CPA. In the present investigation, we aimed to elucidate the clinical course and prognostic factors of CPA in patients with PNTM. METHODS: We retrospectively investigated the medical records of 62 patients with CPA and a history of PNTM who were admitted to Kinki-chuo Chest Medical Center between 2010 and 2015...

Chronic pulmonary aspergillosis (CPA) complicates underlying lung disease, including treated tuberculosis. Measurement of Aspergillus-specific immunoglobulin G (IgG) is a key diagnostic step. Cutoffs have been proposed based on receiver operating characteristic (ROC) curve analyses comparing CPA cases to healthy controls, but performance in at-risk populations with underlying lung disease is unclear. We evaluated optimal cutoffs for the Siemens Immulite Aspergillus-specific IgG assay for CPA diagnosis in relation to large groups of healthy and diseased controls with treated pulmonary tuberculosis...

Aspergillus fumigatus causes life-threatening lung infections in immunocompromised patients. Mouse models are extensively used in research to assess the in vivo efficacy of antifungals. In recent years, there has been an increasing interest in the use of non-invasive imaging techniques to evaluate experimental infections. However, single imaging modalities have limitations concerning the type of information they can provide. In this study, magnetic resonance imaging and bioluminescence imaging were combined to obtain longitudinal information on the extent of developing lesions and fungal load in a leucopenic mouse model of IPA...

An experimental micellar formulation of amphotericin B (AMB) with sodium deoxycholate (DCH), AMB:DCH 1:1.5, was obtained and characterized to determine its aggregation state and particle size. Biodistribution, nephrotoxicity and efficacy against pulmonary aspergillosis in a murine model were studied and compared to the liposomal commercial amphotericin B after intravenous administration. The administration of 5 mg/kg AMB:DCH 1:1.5 presented 2.8-fold higher lung concentrations (18.125 ± 3.985 μg/g, after 6 daily doses) and lower kidney exposure (0...

Severe combined immunodeficiency syndrome (SCID) is a life-threatening condition leading to early infant death as a result of severe infection, due to impaired cellular and humoral immune systems. Various forms of SCID are classified based on the presence or absence of T cells, B cells and natural killer cells. Patients usually present with recurrent infections and failure to thrive. Definitive treatment is hematopoietic stem cell transplantation. To achieve the best outcome, it should be performed prior to the development of severe infection...

REVIEW
S Moura, L Cerqueira, A Almeida
The fungus Aspergillus fumigatus is the main pathogenic agent responsible for invasive pulmonary aspergillosis. Immunocompromised patients are more likely to develop this pathology due to a decrease in the immune system's defense capacity. Despite of the low occurrence of invasive pulmonary aspergillosis, this pathology presents high rates of mortality, mostly due to late and unspecific diagnosis. Currently, the diagnostic methods used to detect this fungal infection are conventional mycological examination (direct microscopic examination, histological examination, and culture), imaging, non-culture-based tests for the detection of galactomannan, β(1,3)-glucan and an extracellular glycoprotein, and molecular tests based on PCR...

Febrile neutropenia (FN) is associated with substantial morbidity and necessitate empiric broad spectrum antibiotic treatment. We evaluated a risk-guided FN management strategy using empiric piperacillin-tazobactam and carbapenem in a prospective cohort study. The analysis involved 723 FN episodes in hospitalised adult patients, including those with severe sepsis or prior infection/colonisation with extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. Propensity score matching analysis was used to adjust for baseline differences between treatment groups and produced 267 matched pairs...

Background: The prevalence of adrenal insufficiency (AI) in cystic fibrosis (CF) is unknown. The frequent use of glucocorticoids (inhaled or systemic) may induce the long-term suppression of the hypothalamic-pituitary-adrenal axis. Methods: We reviewed the results of adrenocorticotropic hormone (ACTH) stimulation tests done over a 10-year period to evaluate adrenal function in 69 CF patients of the CHUM CF clinic. Clinical characteristics of AI patients were compared to adrenal-sufficient (AS) patients...

REVIEW
Christopher R Thornton
Invasive pulmonary aspergillosis (IPA) is a life-threatening lung disease of immuno-compromised humans caused by the ubiquitous environmental mold Aspergillus . Biomarker tests for the disease lack sensitivity and specificity, and culture of the fungus from invasive lung biopsy is slow, insensitive, and undesirable in critically ill patients. A computed tomogram (CT) of the chest offers a simple non-intrusive diagnostic procedure for rapid decision making, and so is used in many hematology units to drive antifungal treatment...

Background: Establishing rapid diagnoses of invasive aspergillosis (IA) is priority, given poor outcomes of late therapy. Non-culture based tests that detect galactomannan and β-D glucan are available, but are technically cumbersome and rely on invasive sampling (blood or bronchoalveolar lavage). Methods: We optimized a lateral flow dipstick assay using the galactofuranose -specific monoclonal antibody (mAb476), which was previously shown to recognize urine antigens after Aspergillus fumigatus pulmonary infection in an`imals...
