    Notes: Summary Hepatitis B core antigen (HBcAg) synthesized in E. coli was used for determination of immunoglobulin M class-specific antibodies against HBcAg. It was found that 98% of cases with acute hepatitis B surface antigen (HBsAg) positive hepatitis type B were anti-HBc immunoglobulin M (IgM) positive. Atypical hepatitis B was detected in 33% of anti-HBc-positive HBsAg-negative cases with acute hepatitis. Anti-HBc IgM was positive for 6 months in acute resolving hepatitis type B, whereas cases resulting in chronic hepatitis B remained anti-HBc IgM-positive for up to 900 days. Chronic HBsAg carriers with severe liver disease had anti-HBc IgM more often than individuals with minor liver damage; 83% of HBsAg-positive liver cirrhoses, 63% of chronic aggressive hepatitis, 50% of HBsAg-positive liver carcinoma, but only 17% of chronic persistent hepatitis or 7% of healthy blood donors were anti-HBc IgM-positive. Determination of anti-HBc IgM is useful in detecting atypical hepatitis B virus infections without HBsAg in serum and, with some restrictions, in discriminating acute and chronic hepatitis type B.

    Description / Table of Contents: Zusammenfassung. Verschiedene Krankheiten aus dem Kreis der sog. übertragbaren („transmissible“) spongiformen Encephalopathien (TSE) sind beim Menschen und im Tierreich bekannt. Doch erst in jüngster Zeit sind die TSE durch die BSE-Epidemie (BSE = bovine spongiforme Encephalopathie) und die Beschreibung der wahrscheinlich damit zusammenhängenden neuen Variante der Creutzfeldt-Jakob-Krankheit (nvCJK) ins Bewußtsein der (Fach-)Öffentlichkeit gerückt. Über die Natur der zugrundeliegenden Erreger wird nach wie vor gestritten; keines der vorgeschlagenen Konzepte (Prionen, Viren) vermag alle Aspekte befriedigend zu erklären. Fest steht jedoch eine genetische Komponente bei Infektionsempfänglichkeit und Krankheitsentwicklung sowie die Übertragbarkeit auch über Artschranken hinweg. Diese Arbeit gibt einen Überblick über erste Ergebnisse der in letzter Zeit intensiver betriebenen Grundlagenforschung sowie über jüngste Entwicklungen, sowohl was den Stand der (Früh-)Diagnostik in vivo anbelangt als auch den Ausschluß von möglichen (auch iatrogenen) Übertragungswegen.
    Notes: Summary. Different diseases of the transmissible spongiform encephalopathy (TSE) group are known to affect humans and various animals. Owing to the bovine spongiform encephalopathy (BSE) epidemic and the description of the new variant of Creutzfeldt-Jakob disease (nvCJD), which is probably linked to BSE, TSE received much attention. The nature of the causative agent is still disputed; none of the proposed concepts (prions, viruses) can explain all features. It is clear, however, that there is a genetic component in susceptibility to infection and in development of disease and that transmission may cross the species barrier. This paper gives an overview of the first results and latest developments of basic TSE research that has focused on in vivo early diagnosis and the prevention of possible (also iatrogenic) transmission.
