We examined the relationship between the metabolic processes of carbon catabolite repression (CCR), nitrogen catabolite repression (NCR) and virulence in a variety of A. fumigatus clinical isolates. A considerable amount of heterogeneity with respect to the degree of CCR and NCR was observed and a positive correlation between NCR and virulence in a neutropenic mouse model of pulmonary aspergillosis (PA) was found. Isolate Afs35 was selected for further analysis and compared to the reference strain A1163, with both strains presenting the same degree of virulence in a neutropenic mouse model of PA. Afs35 metabolome analysis ...

Conclusion: This prospective multicenter study provides information on the current incidence and outcome of IFD in the real life setting. Practice variation between the centers may help to ultimately improve antifungal management in children at highest risk for IFDs. Introduction Available data on the incidence and outcome of invasive fungal diseases (IFD) in children treated for a hematological malignancy or undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are mostly based on single site, retrospective studies or on studies performed prior to the availability of newer compounds such as broad-sp...

We report that the bifunctional compounds enhance the interactions between primary human neutrophils and A. fumigatus in vitro, using three microfluidic assay platforms. The bifunctional compounds significantly enhance the recruitment of neutrophils, increase hyphae killing by neutrophils in a uniform concentration of drug, and decrease hyphal tip growth velocity in the presence of neutrophils compared to the antifungal targeting moiety alone. We validated that the bifunctional compounds are also effective in vivo, using a zebrafish infection model with neutrophils expressing the appropriate EM receptor. We measured signif...

Authors: Deepak L, Singh Rajput M, Sharma B Abstract Summary: Allergic bronchopulmonary mycosis (ABPM) is a clinical syndrome associated with immune sensitivity to various fungi that colonize the airways. Early diagnosis and treatment with systemic corticosteroids is the key in preventing the progression of the disease to irreversible lung fibrosis. Although Aspergillus has progressively gained recognition as a causative agent in past few decades, other fungi, that have been reported to cause ABPM, are not yet widely evaluated. We studied hundred and two patients with asthma for occurrence of ABPM. Patients were te...

Hedayati, A.A. Velayati, M.T. HedayatiAbstractA 12-year-old boy with cystic fibrosis (CF) and a history of glucocorticoid-dependent allergic bronchopulmonary aspergillosis (ABPA) was referred to our hospital. The ABPA was diagnosed when he was 8 years old and he had been treated with several course of oral glucocorticoids for recurrent exacerbations. He was readmitted when aged 12 with a history of worsening shortness of breath and c...

She was diagnosed as having allergic bronchopulmonary aspergillosis on the basis of clinical symptoms, peripheral blood eosinophilia, elevated total serum immunoglobulin E value, positive results of specific IgE and precipitating antibodies against Aspergillus sp., central bronchiectasis, and mucoid impactio...

We describe the case of an 11-year-old boy, with late initial presentation of CGD, which was revealed by fulminant aspergillus pneumonia. He was successfully treated with an association of high doses of steroids and voriconazole. PMID: 30340947 [PubMed - as supplied by publisher]

Becker, Peter Pickkers, Frank L. van de Veerdonk, Yvonne F. Heijdra, Eva KolwijckAbstractInvasive pulmonary aspergillosis is increasingly described in non-neutropenic patients, such as patients with COPD receiving corticosteroids and the critically ill. Here, we present a case of a lethal pulmonary Aspergillus niger infection in a COPD patient. Immunological tests showed an impaired innate and adaptive immune response to Aspergillus. A history of COPD, unresponsive...

We present a case of a 61-year-old man with hepatocellular carcinoma and a previous history of metabolic and alcoholic cirrhosis who underwent orthotopic liver transplant. The immunosuppression regimen consisted of corticosteroids, calcineurin inhibitor, and mammalian target of rapamycin complex 1 inhibitor. Nine days after surgery, the patient developed leukopenia and skin rash. After confirmation of graft-versus-host disease by chimerism and skin biopsy, etanercept, a novel anti-tumor necrosis factor-alpha drug used for patients with hematologic and rheumatologic disease, was administrated. Unfortunately, no clinical imp...
