Trichosporon asahii is an opportunistic yeastlike fungus commonly associated with systemic infections in immunocompromised patients. Neutropenia is recognized as the main risk factor in infections by T. asahii; however, little is known about the cytokine response during trichosporonosis. Here, we evaluated systemic and local cytokine production and histological damage in immunocompetent mice during systemic infection with T. asahii. We found a significant increased presence of G-CSF, TNF-α, IFN-γ, and IL-6 in sera samples...

Granulocyte transfusions have a long history of being used in patients with neutropenia or neutrophil dysfunction to prevent and treat invasive fungal infections. However, there are limited and conflicting data concerning its clinical effectiveness, considerable variations in current granulocyte transfusion practices, and uncertainties about its benefit as an adjunct to modern antifungal therapy. In this review, we provide an overview on granulocyte transfusions and summarize the evidence on their role in the prevention and treatment of invasive fungal infections...

Invasive aspergillosis (IA) is one of the most difficult to treat and, consequently, one of the most lethal fungal infections known to man. Continued use of immunosuppressive agents during chemotherapy and organ transplantation often leads to the development of neutropenia, the primary risk factor for IA. However, IA is also becoming more appreciated in chronic diseases associated with corticosteroid therapy. The innate immune response to Aspergillus fumigatus, the primary agent in IA, plays a pivotal role in the recognition and elimination of organisms from the pulmonary system...

Interstitial pneumonitis is a classical complication of many drugs. Pulmonary toxicity due to 5-azacytidine, a deoxyribonucleic acid methyltransferase inhibitor and cytotoxic drug, has rarely been reported. We report a 67-year-old female myelodysplastic syndrome patient treated with 5-azacytidine at the conventional dosage of 75 mg/m(2) for 7 days. One week after starting she developed moderate fever along with dry cough and subsequently her temperature rose to 39.5 °C. She was placed under broad-spectrum antibiotics based on the protocol for febrile neutropenia, including ciprofloxacin 750 mg twice daily, ceftazidime 1 g three times daily (tid), and sulfamethoxazole/trimethoprim 400 mg/80 mg tid...

Aspergillus lateral-flow device (LFD) was recently introduced as a practical tool for the diagnosis of invasive aspergillosis (IA). We investigated the performance of Aspergillus-LFD as a point-of-care test for the diagnosis of IA. Serum samples were collected twice weekly from patients who received intensive chemotherapy for acute leukemia, or recepients of allogeneic stem cell transplantation. Aspergillus galactomannan (GM) antigen, 1,3-beta-d-glucan and Aspergillus-LFD tests were carried out according to manufacturers' recommendations...

Saprochaete and Geotrichum spp. are rare emerging fungi causing invasive fungal diseases in immunosuppressed patients and scarce evidence is available for treatment decisions. Among 505 cases of rare IFD from the FungiScope(™) registry, we identified 23 cases of invasive infections caused by these fungi reported from 10 countries over a 12-year period. All cases were adults and previous chemotherapy with associated neutropenia was the most common co-morbidity. Fungaemia was confirmed in 14 (61%) cases and deep organ involvement included lungs, liver, spleen, central nervous system and kidneys...

Despite improvements in diagnosis and treatment, infections are still major cause of morbidity and mortality in children with febrile neutropenia. In majority of febrile episodes, infection source cannot be defined. In this study, we aim to identify the earlier predictors of bacteremia/fungemia and a useful cytokine identify the source of infections and to discriminate the patients with culture-confirmed bacterial/fungal infection. The most sensitive cytokine was IL (Interleukin)-10 and the most specific was IL-8 in predicting culture-confirmed...

COMMENT
Andrea Cortegiani, Vincenzo Russotto, Antonino Giarratano
Clinical Question: Are antifungal agents associated with lower rates of mortality and invasive fungal infections when administered before definitive diagnosis of an invasive fungal infection in critically ill patients without neutropenia? Bottom Line: Antifungal treatment administered prior to diagnosis of an invasive fungal infection is not associated with either higher or lower rates of all-cause mortality. Antifungal treatment in this setting is associated with lower rates of invasive fungal infections compared with placebo or no intervention in critically ill patients without neutropenia, but the quality of the evidence is low...

Recipients of hematopoietic stem cell transplantation (HSCT) are at substantial risk of bacterial, fungal, viral, and parasitic infections depending on the time elapsed since transplantation, presence of graft-versus-host disease (GVHD), and the degree of immunosuppression. Infectious complications in HSCT recipients are associated with high morbidity and mortality. Bacterial infections constitute the major cause of infectious complications, especially in the early post-transplant period. The emergence of antibacterial resistance complicates the management of bacterial infections in this patient group...

Invasive fungal diseases (IFDs) are a leading cause of morbidity and mortality among immunocompromised patients with bone marrow failure syndromes, hematological malignancies, hematopoietic stem cell transplantation (HSCT), those admitted in intensive care units (ICUs) and those with prolonged febrile neutropenia. IFDs occur in a setting of multiple morbidities and are associated with case fatality rates between 30 and 70%. Along with the development of classes and compounds, the last two decades have seen substantial improvements in the prevention and management of these infections and an overall increased use of antifungal agents...
