    Notes: Summary To date, long-term intravenous drug users studied at regional European centers of illicit drug use have had a high number of LAV/HTLV-III infections. Among 200 patients remanded by court or referred from prison to a special clinic in northern Germany for young delinquent drug abusers, 26 (17%) of 157 IV drug abusers were HTLV-III seropositive. With 40% seropositive, female patients showed a significantly higher prevalence of HTLV-III infection than males. The results of longitudinal serological, immunological, and clinical observations over periods of 12 months and 2–3 years indicate that under conditions of continuous medical surveillance, sound preventive counseling, and steady therapeutic care during long-term coeducative residential treatment of drug abusers, neither detectable HTLV-III transmission nor definite progression of HTLV-III induced impairment of immune regulatory functions must ensue.

    Description / Table of Contents: Zusammenfassung Bei Patienten mit Hyperlipoproteinämien (HLP) Typ IIa (n=10), Typ IIb (n=9), Typ IV (n=24) und Typ V (n=11) sind die vier neutralen Glycosphingolipide im Plasma gegenüber einem gesunden Kontrollkollektiv (n=23) erhöht. Die Erhöhung der Monohexosylceramide ist bei allen HLP-Typen am stärksten und in der Varianzanalyse statistisch signifikant (p〈1%). Die Tri- und Tetrahexosylceramide zeigen nur bei einzelnen Typen statistisch auffällige Anstiege, die Zunahme der Dihexosylceramidspiegel ist nicht signifikant. Die prozentuale Verteilung aller Glycosphingolipidfraktionen steigt deutlich an in den VLDL bei HLP Typ IV und Typ IIb, in den LDL bei HLP Typ IIa. Es besteht eine Parallelität zu dem vermehrten Gehalt an Prä-β-Lipoproteinen beziehungsweise an β-Lipoproteinen. Die Untersuchungen führen zur Schlußfolgerung, daß die Erhöhung der Glycosphingolipide im Plasma eine Folge der Fettstoffwechselstörung ist. Weiterhin wird angenommen, daß ein Teil der Glycosphingolipide des Plasmas in der Leber synthetisiert wird entsprechend den VLDL. Die Rolle der Plasmaglycosphingolipide in der Atherogenese wird diskutiert.
    Notes: Summary There are mainly four neutral glycosphingolipids in human blood plasma: Monohexosyl, dihexosyl, trihexosyl and tetrahexosyl ceramide. In patients with hyperlipoproteinemia (hlp) type IIa (n=10), type IIb (n=9), type IV (n=24), and type V (n=11) all four fractions of plasma glycosphingolipids were elevated compared to healthy subjects (n=23). In all types of hlp monohexosyl ceramides were significantly augmented (p〈1%). Trihexosyl and tetrahexosyl ceramides demonstrated only in single types statistically striking elevation. There was no significant elevation of dihexosyl ceramides. In the VLDL the distribution of all glycosphingolipids showed increase in hlp type IV and type IIb. In the LDL the distribution showed increase in type IIa. There exists a strong correlation with the elevated prae-β-lipoproteins respectively β-lipoproteins. It is concluded that the elevation of glycosphingolipid levels in plasma is a metabolic consequence of hyperlipoproteinemia. It is considered that a part of plasma glycosphingolipids is de novo synthezised by the liver like VLDL. The role of plasma glycosphingolipids in atherogenesis is discussed.

    Description / Table of Contents: Zusammenfassung Im menschlichen Blutplasma kommen hauptsächlich vier neutrale Glycosphingolipidfraktionen vor: Monohexosyl-, Dihexosyl-, Trihexosyl- und Tetrahexosylceramid. Bei Patienten mit akuter Hepatitis (n=21) sind in der akuten Phase die vier Glycosphingolipidfraktionen im Plasma gegenüber einem gesunden Kontrollkollektiv (n=23) erhöht. Mit Ausnahme der Trihexosylceramidfraktion läßt sich die Erhöhung statistisch sichern. Gleichzeitig kommt es in der akuten Phase der Hepatitis zu einer statistisch signifikanten Cholesterin- und Triglyceriderhöhung. Es wird gefolgert, daß die Erhöhung der Glycosphingolipide im Plasma bei der akuten Hepatitis im Zusammenhang mit der Fettstoffwechselstörung auftritt und daß ein Teil der Glycosphingolipide des Plasmas in der Leber synthetisiert wird entsprechend den VLDL.
    Notes: Summary There are mainly four neutral glycosphingolipids in human blood plasma: Monohexosyl, dihexosyl, trihexosyl and tetrahexosyl ceramide. In patients with viral hepatitis (n=21) during the acute phase all four fractions of plasma glycosphingolipids were elevated compared to healthy subjects (n=23). With the exception of trihexosyl ceramide all fractions demonstrated statistically striking elevations in the acute phase of viral hepatitis. Simultaneously in the acute phase of hepatitis triglycerides and cholesterol in serum were significantly increased. It is concluded the elevation of glycosphingolipid levels in plasma is a metabolic consequence of hyperlipoproteinemia. Furthermore it is supposed that a part of plasma glycosphingolipids is synthezised de novo by the liver like VLDL.
