Plasma glycosphingolipids in diabetics and normals. 1975

G J Kremer, and W Atzpodien, and E Schnellbacher

In diabetic patients with hyperlipoproteinemia type IV the monohexosyl ceramide concentration in blood plasma is significantly elevated. This augmentation can be attributed to an increased monohexosyl ceramide content of the BLDL plasma fraction. In contrast, the di-, tri-, the tetrahexosyl ceramide levels remain within normal limits. In normolipidemic diabetics of comparable age, sex, and weight classes and of comparable metabolic control no elevations of glycolipid fractions could be found. However, patients with primary hyperlipoproteinemia type IV show an increase of monohexosyl ceramide concentrations in blood plasma. Therefore, the augmentation of monohexosyl ceramide levels in plasma of hyperlipidemic diabetic patients seems rather a metabolic consequence of hyperlipoproteinemia than of diabetes per se. A clearcut explantation for the monohexosyl ceramide elevations in the studied groups cannot be given at present time.

UI MeSH Term Description Entries
D006949 Hyperlipidemias Conditions with excess LIPIDS in the blood. Hyperlipemia,Hyperlipidemia,Lipemia,Lipidemia,Hyperlipemias,Lipemias,Lipidemias
D008079 Lipoproteins, VLDL A class of lipoproteins of very light (0.93-1.006 g/ml) large size (30-80 nm) particles with a core composed mainly of TRIGLYCERIDES and a surface monolayer of PHOSPHOLIPIDS and CHOLESTEROL into which are imbedded the apolipoproteins B, E, and C. VLDL facilitates the transport of endogenously made triglycerides to extrahepatic tissues. As triglycerides and Apo C are removed, VLDL is converted to INTERMEDIATE-DENSITY LIPOPROTEINS, then to LOW-DENSITY LIPOPROTEINS from which cholesterol is delivered to the extrahepatic tissues.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009765 Obesity A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).

D002518 Ceramides Members of the class of neutral glycosphingolipids. They are the basic units of SPHINGOLIPIDS. They are sphingoids attached via their amino groups to a long chain fatty acyl group. They abnormally accumulate in FABRY DISEASE. Ceramide
D003920 Diabetes Mellitus A heterogeneous group of disorders characterized by HYPERGLYCEMIA and GLUCOSE INTOLERANCE.
D005260 Female Females
D006017 Glycolipids Any compound containing one or more monosaccharide residues bound by a glycosidic linkage to a hydrophobic moiety such as an acylglycerol (see GLYCERIDES), a sphingoid, a ceramide (CERAMIDES) (N-acylsphingoid) or a prenyl phosphate. (From IUPAC's webpage) Glycolipid
