Because of the limited access to more powerful diagnostic tools, there is a paucity of data regarding the burden of fungal infections in Burkina Faso. The aim of this study was to estimate the incidence and prevalence of serious fungal infections in this sub-Saharan country. We primarily used the national demographic data and performed a PubMed search to retrieve all published papers on fungal infections from Burkina Faso and its surrounding West African countries. Considering the prevalence of HIV infection (0...

OBJECTIVES: In patients with very severe aplastic anemia (VSAA), neutropenia is prolonged and persistent, resulting in refractory overwhelming infections. Hematopoiesis recovery is urgently needed. METHODS: Six patients with de novo VSAA lacking HLA-identical sibling donors and those who experienced refractory infections, underwent haploidentical related donor (HRD) hematopoietic stem cell transplantation (HSCT) as a first-line therapy. The conditioning regimen consisted of busulfan, cyclophosphamide and rabbit antithymocyte globulin...

Neurologic complications after solid-organ transplant reveal a great spectrum of pathologies. Intracranial hemorrhages, cerebral ischemic lesions, infarctions, lymphoproliferative disorders, and infections, including aspergillosis, have been observed after liver transplant. Fungi constitute nearly 5% of all central nervous system infections, mainly occurring in immunocompromised patients. The most common causative agent is Aspergillus species. It presents either as maxillary sinusitis or pulmonary infection...

Invasive pulmonary aspergillosis is an infection seen in patients receiving intensive immunosuppressive regimens, such as transplant recipients. Some risk factors that increase the incidence of infection have been determined, and patients defined as having high risk are recommended to take antifungal prophylaxis and be monitored closely. Here, we present a liver transplant patient with mild respiratory symptoms and a normal chest radiography on day 26 posttransplant. However, he had acute renal failure and underwent hemodialysis, which are both defined to increase significantly the risk of aspergillosis...

Cavities are occasionally encountered on thoracic imaging. Their differential diagnosis is large and includes, among others, various infections, autoimmune conditions and primary and metastatic malignancies. We offer an algorithmic approach to their evaluation by initially excluding mimics of cavities then broadly classifying them according to the duration of clinical symptoms and radiological abnormalities.. An acute or subacute process (<12 weeks) suggests common bacterial and uncommon nocardial and fungal causes of pulmonary abscesses, necrotizing pneumonias, and septic emboli...

Introduction: Invasive' pulmonary aspergillosis (IPA) has been one of the major causes of mortality in immunocompromised patients. The gold standard method for a diagnosis of IPA is histopathological examination of the lung tissue; however, post-procedural bleeding limits the feasibility of lung biopsy. The European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and The National Institute of Allergy and Infectious Disease Mycoses Study Group (EORTC/MSG) defined IPA...

The role of vitamin D in the regulation of lung immune defense and inflammatory response has attracted more and more attention. Vitamin D deficiency is closely related to respiratory tract infections. However, few studies have elucidated the mechanism of vitamin D deficiency on host pulmonary resistance to Aspergillus fumigatus ( A. fumigatus ). In this paper, the role of autophagy and Treg regulation in the treatment of rat models of A. fumigatus infection with vitamin D was investigated. We intratracheally injected the A...

The incidence of invasive fungal infections has risen dramatically in the past decades. Current antifungal drugs are either toxic, likely to interact with other drugs, have a narrow spectrum of activity or induce fungal resistance. Hence, there is a great need for new antifungals, possibly with novel mechanisms of action. Previously our group reported an acylhydrazone called BHBM that targeted the sphingolipid pathway, and showed strong antifungal activity against several fungi. In this study, we screened 19 derivatives of BHBM...

The present study investigated the improvement in the diagnosis of invasive pulmonary aspergillosis (IPA) adding a molecular test on bronchoalveolar lavage (BAL) to the routine diagnostic approach including microscopy, culture and galactomannan (GM) immunoassay. A total of 133 BAL samples were retrospectively tested for the Aspergillus DNA: 112 samples were from immunocompromised patients at risk of invasive fungal infection and 21 were from patients not at risk and without clinical evidence of IPA. The latter samples were used to identify the cut-off of positivity for the molecular test...

OBJECTIVE: Pulmonary mucormycosis is an aggressive opportunistic fungal infection. We set out to evaluate the CT and MRI features of pulmonary mucormycosis. MATERIALS AND METHODS: Through a search of the electronic medical record from 2007 to 2017, we identified 30 patients with definite or probable mucormycosis. Two radiologists reviewed the initial chest CT examinations for the presence of features including the "reverse halo" sign, large ground-glass halo, and peripheral lesion distribution...

Cryptococcus neoformans is a common environmental saprophyte and human fungal pathogen that primarily causes disease in immunocompromised individuals. Similar to many environmentally acquired human fungal pathogens, C. neoformans initiates infection in the lungs. However, the main driver of mortality is invasive cryptococcosis leading to fungal meningitis. After C. neoformans gains a foothold in the lungs, a critical early step in invasion is transversal of the respiratory epithelium. In this review, we summarize current knowledge relating to pulmonary escape...

Mucormycosis is an opportunistic fungal infection that can infect different regions of the body. This entity may present in rhinocerebral, pulmonary, cutaneous, and disseminated forms. Although pulmonary mucormycosis is usually seen as an invasive parenchymal consolidation or cavitation, it may rarely present as an endobronchial mass. We describe a case of endobronchial mucormycosis in which the fungal mass was completely removed via rigid bronchoscopy before medical therapy.

Endemic mycoses are systemic fungal infections. Histoplasmosis is endemic in all temperate areas of the world; coccidioidomycosis and paracoccidioidomycosis are only present in the American continent. These pathogens are not present in Spain, but in the last years there has been an increase of reported cases due to migration and temporary movements. We obtained from the Spanish hospitals records clinical and demographic data of all hospitalized cases between 1997 and 2014. There were 286 cases of histoplasmosis, 94 of Coccidioidomycosis and 25 of paracoccidioidomycosis...

Respiratory diseases, such as pulmonary infections, are an important cause of morbidity and mortality worldwide. Preclinical studies often require invasive techniques to evaluate the extent of infection. Fibered confocal fluorescence microscopy (FCFM) is an emerging optical imaging technique that allows for real-time detection of fluorescently labeled cells within live animals, thereby bridging the gap between in vivo whole-body imaging methods and traditional histological examinations. Previously, the use of FCFM in preclinical lung research was limited to endpoint observations due to the invasive procedures required to access lungs...

With overuse of the broad-spectrum antibiotics, the pulmonary fungal infection increasingly becomes the most common complication associated with senile pulmonary tuberculosis (TB) and attracts intensive attentions from clinicians. Here we presented the retrospective analysis of impact of fluconazole treatment on the clinical outcome and immune response in fungal co-infected tuberculosis patients. A randomized, double-blind, placebo-controlled trial of fluconazole (100 mg per day for consecutive weeks) in fungal-positive senile tuberculosis patients was conducted in our hospital...
