Febrile neutropenia is a very common complication in patients with hematological malignancies receiving chemotherapy, and is associated with high morbidity and mortality. Infections caused by multidrug-resistant bacteria have become a therapeutic challenge in this high-risk patient population, since inadequate initial empirical treatment can seriously compromise prognosis. However, reducing antimicrobial exposure is one of the most significant cornerstones in the fight against resistance. The objective of these new guidelines is to update recommendations for the initial management of hematological patients who develop febrile neutropenia in this scenario of multidrug resistance. The two participating Societies (the Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica [Spanish Society of Infectious Diseases and Clinical Microbiology] and the Sociedad Española de Hematología y Hemoterapia [Spanish Society of Haematology and Haemotherapy]), designated a panel of experts in the field to provide evidence-based recommendations in response to common clinical questions. This document is primarily focused on bacterial infections. Other aspects related to opportunistic infections, such as those caused by fungi or other microorganisms, especially in hematopoietic stem cell transplantation, are also touched upon., (Copyright © 2019 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Background: The incidence of invasive aspergillosis has increased worldwide. Information regarding the clinical characteristics of patients with extrapulmonary involvement is scarce., Objective: We aimed to describe the pathogenesis, characteristics and outcomes of patients with invasive aspergillosis and extrapulmonary disease., Methods: A retrospective study conducted in a university hospital in Barcelona, Spain (1995-2011)., Results: A total of 12 cases of invasive aspergillosis and extrapulmonary involvement were found. The most common clinical manifestations were invasive sinusitis, early postoperative prosthetic valve endocarditis, fungaemia, postoperative meningitis, multiple brain abscesses and lumbar spondylitis with epidural abscess. Sinusitis occurred frequently in patients without immunosuppression and had invasive brain involvement in one case. Endocarditis was associated with multiple septic metastases. Concomitant lung involvement was documented in 5 cases. The strains isolated were Aspergillus fumigatus (5), Aspergillus flavus (3), and Aspergillus niger (2). The species of Aspergillus was not established for 3 isolates. All patients were treated with antifungals and surgery was performed in 8 cases. Outcome was related with the source of infection; all patients with invasive sinusitis survived, while the remaining patients had a high mortality rate (88%)., Conclusions: Invasive aspergillosis with extrapulmonary involvement is rare. The most common presentation is invasive sinusitis, which has a lower mortality. Other clinical forms with extrapulmonary involvement were associated with severe immunosuppression or previous surgery, and had a poor outcome., (Copyright © 2011 Revista Iberoamericana de Micología.
