Abstract
Summary. Eight Aspergillus antibody detection assays — three indirect haemagglutination assays (IHA-LD, IHA-Roche, IHA-Fumouze), three enzyme immunoassays (EIA-IgG, EIA-IgM, EIA-IgA, DDV) and two complement fixation tests (CF-metabolic and CF-somatic, Virion — and one latex agglutination test (LAT) for Aspergillus galac-tomannan antigen detection (Sanofi Pasteur) were evaluated in 14 patients with proven invasive aspergillosis (a total of 47 serum samples and one cerebrospinal fluid sample) and in 68 selected control individuals (one selected serum sample each). For the antibody tests, sensitivity ranged from 14% to 36% and specificity from 72% to 99%. The antigen detection test had a sensitivity of 36% and a specificity of 100%. Currently commercially available antibody detection assays for the serodiagnosis of invasive aspergillosis are inadequate. The antigen detection test appears to be highly specific, but lacks sufficient sensitivity. Zusammenfassung. Acht Aspergillus-Antikörpernachweis-Systeme, nämlich drei indirekte Hämagglutinationsteste (IHA-LD, IHA-Roche, IHA-Fumouze), drei Enzymimmunassays (EIA-IgG, EIA-IgM, EIA-IgA, DDV) und zwei Komplementbindungsreaktionen (CF-metabolic und CF-somatic, Virion) sowie ein Latex-Agglutinationstest zum Nachweis von Aspergillus-Galaktomannan-Antigen (Sanofi-Pasteur) wurden an insgesamt 14 Fällen bewiesener invasiver Aspergillose (47 Serumproben und ein Liquor) und einer Kontrollgruppe von 68 Probanden (je eine Serumprobe) bewertet. Bei diesen Antikörper-Nachweisen lag die Sensitivität zwischen 14% und 36% und die Spezifität zwischen 72% und 99%. Der Antigen-Nachweis zeigte eine Sensitivität von 36% und eine Spezifität von 100%. Die derzeit erhältlichen Antikörpernachweis-Systeme zur Serodiagnose der invasiven Aspergillose sind unbefriedigend. Der Antigennachweis ist hochspezifisch, doch ist auch seine Sensitivität unzureichend.Keywords
