TL;DR: These revised definitions of invasive fungal disease are intended to advance clinical and epidemiological research and may serve as a useful model for defining other infections in high-risk patients.
Journal ArticleDOI
Defining Opportunistic Invasive Fungal Infections in Immunocompromised Patients with Cancer and Hematopoietic Stem Cell Transplants: An International Consensus
Sibel Ascioglu,John H. Rex,B.E. de Pauw,John E. Bennett,J. Bille,F. Crokaert,David W. Denning,J.P. Donnelly,J. E. Edwards,Z. Erjavec,D. Fiere,O. Lortholary,Johan Maertens,Jacques F. Meis,Thomas F. Patterson,J. Ritter,D. Selleslag,Palak Shah,David A. Stevens,Thomas J. Walsh +19 more
TL;DR: A set of research-oriented definitions for the IFIs most often seen and studied in immunocompromised patients with cancer is proposed and three levels of probability are proposed: "proven," "probable," and "possible."
Journal ArticleDOI
Bronchoalveolar Lavage Fluid Galactomannan for the Diagnosis of Invasive Pulmonary Aspergillosis in Patients with Hematologic Diseases
Johan Maertens,Vincent Maertens,Koen Theunissen,Wouter Meersseman,Philippe Meersseman,Stef Meers,Eric Verbeken,Gregor Verhoef,Johan Van Eldere,Katrien Lagrou +9 more
TL;DR: BAL GM is a valuable adjunctive diagnostic tool to other conventional microbiologic and radiologic studies and a trend toward decreased sensitivity in patients receiving mold-active prophylaxis was noted.
Journal ArticleDOI
Optimization of the Cutoff Value for the Aspergillus Double-Sandwich Enzyme Immunoassay
Johan Maertens,Rocus R. Klont,Christine Masson,Koen Theunissen,Wouter Meersseman,Katrien Lagrou,Christine Heinen,Brigitte Crépin,Johan Van Eldere,Marc Tabouret,J. Peter Donnelly,Paul E. Verweij +11 more
TL;DR: A cutoff OD index of 0.5--identical to the approved cutoff in the United States--improves the overall performance of the PA-EIA for adult hematology patients.
Journal ArticleDOI
Detection of Galactomannan in Bronchoalveolar Lavage Fluid Samples of Patients at Risk for Invasive Pulmonary Aspergillosis: Analytical and Clinical Validity
Jorien D'Haese,K Theunissen,Edith Vermeulen,Hélène Schoemans,Greet De Vlieger,Liesbet Lammertijn,Philippe Meersseman,Wouter Meersseman,Katrien Lagrou,Johan Maertens +9 more
TL;DR: Invasive pulmonary aspergillosis (IPA) is frequent and often fatal in immunosuppressed patients as mentioned in this paper, and timely diagnosis of IPA improves survival but is difficult to make.
