Aspergillus fumigatusand Aspergillosis

Abstract: SUMMARY Aspergillus fumigatus is one of the most ubiquitous of the airborne saprophytic fungi. Humans and animals constantly inhale numerous conidia of this fungus. The conidia are normally eliminated in the immunocompetent host by innate immune mechanisms, and aspergilloma and allergic bronchopulmonary aspergillosis, uncommon clinical syndromes, are the only infections observed in such hosts. Thus, A. fumigatus was considered for years to be a weak pathogen. With increases in the number of i… Show more

“…Our patients were receiving high doses of corticosteroids and broad-spectrum antibiotics when IPA was diagnosed. Steroids are increasingly recognized as a major risk factor for the development of IPA [15,32,33]. Indeed, corticosteroids depress both macrophage and polymorphonuclear function [11,12], cells that form the most important line of protection against fungi [34].…”

“…Anti-IL-18 treatment was associated with significantly decreased neutrophil accumulation in the BAL at 3 days after conidia challenge in A. fumigatus-sensitized mice. Since neutrophils have been shown to be intimately involved in the clearance of conidia from the lungs [26], decreased neutrophil migration into the airways of anti-IL-18-treated mice probably allowed the retention of conidia.…”

“…Der relative Rückgang der invasiven Candidamykosen, der auch außerhalb Europas registriert wurde [4,7], wurde auf den breiten, auch prophylaktischen Einsatz des Triazol-Antimykotikums Fluconazol zurückgeführt, das gegen Aspergillen leider kaum wirkt. Das erneuerte Interesse an Aspergillosen hat seinen Niederschlag in einer Reihe von Übersichts-artikeln gefunden, in denen die Aspekte dieser wohl meistgefürchteten Infektionskrankheit der immunsupprimierten Patienten behandelt werden [3,4,8,9,10]. Die hohe Letalität von hämatologi-schen Patienten mit invasiven pulmonalen Aspergillosen, die unbehandelt über 90% beträgt [11], stellt deshalb eine Herausforderung hinsichtlich der Entwicklung neuer antimykotischer Therapien dar, auf die am Ende dieser Übersicht eingegangen werden soll.…”

“…Unter den rund 160 Aspergillusarten ist A. fumigatus mit Abstand die pathogenste. Diese Besonderheit beruht vermutlich auf der ungewöhnlichen Thermotoleranz des Pilzes (maximal 55°C) und auf der geringen Größe der Konidien (Durchmesser 2,5-3 µ), die bis in die Lungenbläs-chen (Alveolen) vordringen können [10]. Konidien von Aspergillen finden sich unter den Schwebstoffen in der Luft; ihre Konzentration schwankt jah-…”
