    Notes: Summary To establish whether additional therapy with 3-hydroxy-3-methylglutaryl (HMG) coenzyme A (CoA) reductase inhibitors enhances the low-density lipoprotein (LDL) cholesterol lowering effect of LDL apheresis with immunoadsorption in the treatment of patients with familial heterozygous hypercholesterolemia and coronary artery disease we studied eight patients initially on immunoadsorption therapy alone for 3 years. The adding of HMG CoA reductase inhibitors decreased pretreatment LDL cholesterol from 6.76±0.98 to 4.97±0.98 mmol/l and posttreatment LDL cholesterol from 2.33±0.80 to 1.94±0.67 mmol/l and increased pre- and posttreatment high-density lipoprotein (HDL) cholesterol by 0.08 and 0.13 mmol/l respectively. The LDL/HDL ratio was reduced from 4.0 to 2.8 (prior to any therapy the ratio was 13.4). The increase in LDL cholesterol between weekly treatments was less steep under the combined therapy. At the same time the treated plasma volume during LDL apheresis could be decreased from 5070±960 to 4370±1200 1200 ml. We conclude that in patients with severe familial heterozygous hypercholesterolemia LDL apheresis should be combined with HMG CoA reductase inhibitors.

    Fenofibrate and colestipol: Effects on serum and lipoprotein lipids and apolipoproteins in familial hypercholesterolaemia (1986)
    Springer
    European journal of clinical pharmacology 30 (1986), S. 191-194 
    Details
    ISSN: 1432-1041
    Keywords: colestipol ; fenofibrate ; familial hypercholesterolaemia ; lipoproteins ; serum lipids

    Notes: Summary Effects on serum lipoproteins were studied in ten patients with familial hypercholesterolaemia (FH) during consecutive eight-week treatment periods with fenofibrate 0.3 g/day, fenofibrate plus colestipol, 15 g/day, and fenofibrate 0.25 g/day plus colestipol. VLDL, LDL, HDL, HDL2, and HDL3 were isolated by ultracentrifugation and precipitation. Lipids and apolipoproteins A–I and B were determined by enzymatic and immunonephelometric techniques, respectively. Administration of fenofibrate alone resulted in decreases in VLDL and LDL cholesterol (−48% and −18%) and in serum apolipoprotein B (−10%), but in increases in HDL, HDL2, and HDL3 (+25%, +26%, and +24%), and in serum apolipoprotein A–I (+6%). Addition of colestipol produced a further reduction in LDL cholesterol (−31%) and in serum apolipoprotein B (−19%). The effects were maintained with less fenofibrate. In FH, an acceptable therapy combines the favourable effects of sufficient lowering of LDL and of a rise in HDL.

    Short- and long-term effects of lovastatin and pravastatin alone and in combination with cholestyramine on serum lipids, lipoproteins and apolipoproteins in primary hypercholesterolaemia (1992)

    Notes: Summary The effects of the HMG CoA reductase inhibitors lovastatin and pravastatin on serum lipids, lipoproteins and apolipoproteins have been studied in 35 patients with primary hypercholesterolaemia. LDL cholesterol was lowered to the same extent by both agents compared on a mg basis of each drug per day. HDL cholesterol was increased by lovastatin but not by pravastatin. The reduction in serum triglycerides, VLDL triglycerides and VLDL cholesterol was more pronounced after lovastatin than pravastatin. After 1 year the effect of combined treatment with 40 mg pravastatin and 8 g cholestyramine on the reduction in LDL cholesterol (−39%) in 13 patients was comparable to that of 80 mg lovastatin plus 8 g cholestyramine (−40%) in 12 patients with identical baseline values. Differences were also found in the effects of the combination therapy with the two drugs on HDL cholesterol, serum triglycerides, VLDL triglycerides, VLDL cholesterol, and apolipoproteins.

    Description / Table of Contents: Zusammenfassung Aus Hypophysen vom Schwein wurde eine als Peptid A bezeichnete Substanz dargestellt, die sich unter den angegebenen Bedingungen als einheitlich in Säulenchromatographie, Acetatfolien- und Acrylamidgelelektrophorese, Ultrazentrifuge sowie im Immunodiffusionstest erwies. Das mit der Ultrazentrifuge bestimmte Molekulargewicht lag bei 5700. Die minimal wirksame Dosis betrug bei Kaninchen in vitro 0,1 Μg/ml. Nach den vorliegenden Untersuchungen ist anzunehmen, daß Peptid A von MSH, ACTH, STH und TSH verschieden ist.
    Notes: Summary A substance called Peptide A was prepared from pig pituitaries. With the conditions used this substance proved to be homogeneous by column chromatography, acetate and acrylamide gel electrophoresis, ultracentrifugation as well as in the immuno diffusion test. By means of the ultracentrifuge a molecular weight of 5700 was determined. The minimum effective dose in rabbits was 0.1 Μg/ml in vitro. According to the information so far available it would seem that Peptide A differs from MSH, ACTH, STH and TSH.

    Description / Table of Contents: Zusammenfassung 2 Std nach Injektion von 500 μg Fraktion H wurden bei Kaninchen in Fettgewebe und Leber neun Schlüsselenzyme untersucht und mit den Befunden bei Kontrolltieren verglichen. Die signifikante Aktivitätsabnahme von Glucose-6-Phosphathehydrogenase (EC.1.1.1.49), Malatdehydrogenase (EC.1.1.1.37) und α-Glycerophosphatdehydrogenase (EC.1.1.1.8) im Fettgewebe wird mit einer herabgesetzten Triglyceridsynthese unter den Bedingungen der akuten Lipolyse in vivo erklärt. Hexokinase (EC.2.7.1.1), Phosphofructokinase (EC.2.7.1.11) und Pyruvatkinase (EC.2.7.1.40) als Schlüsselenzyme der Glycolyse waren im Fettgewebe nicht signifikant verändert. Neben den genannten Enzymen wurden in der Leber zum gleichen Zeitpunkt außerdem die Glycerokinase (EC.2.7.1.30), die Fructose-1,6-Diphosphatase (EC.3.1.3.11) und die Glucose-6-Phosphatase (EC.3.1.3.9) untersucht; keines der in der Leber bestimmten Enzyme zeigte eine signifikante Aktivitätsänderung.
    Notes: Summary Nine key enzymes in adipose tissue and liver of rabbits are investigated 2 hours after subcutanous injection of 500 μg Fraction H; the results are compared to those from normal animals. The activities of glucose-6-phosphate-dehydrogenase (EC.1.1.1.49), malatdehydrogenase (EC.1.1.1.37) and α-glycero-phosphate-dehydrogenase (EC.1.1.1.8) are diminished in adipose tissue suggesting a lowered glycerid-glycerolsynthesis under the conditions of acute lipolysis in vivo. Hexokinase (EC.2.71.1) phosphofructokinase (EC.2.7.1.11) and pyruvatkinase (EC.2.7.1.40) were not affected significantly in adipose tissue. Besides these enzymes glycerokinase (EC.2.7.1.30), fructose-1,6-diphosphatase (EC.3.1.3.11) and glucose-6-phosphatase (EC.3.1.3.9) were investigated in liver; no significant changes could be demonstrated.

    Description / Table of Contents: Zusammenfassung Es wird über die Gewinnung und weitere säulenchromatographische Reinigung einer lipolytisch wirksamen Substanz aus Schweinehypophysen (Fraktion H) berichtet. Auf Grund der untersuchten physikalisch-chemischen Eigenschaften kann gesagt werden, daß diese Substanz mit der vonRudman et al. extrahierten Fraktion H identisch ist. Durch Chromatographie an Sephadex G 50 konnte die Fraktion weiter gereinigt werden; die lipolytische Aktivität pro Gewichtseinheit wurde dadurch von 0,3 Μg auf 0,1 Μg in vitro bzw. von 125 Μg auf 63 Μg in vivo als minimal wirksame Dosen gesteigert, wie Untersuchungen an Meerschweinchen und Kaninchen ergaben. Eine Kontamination mit lipolytisch wirksamen Mengen ACTH wurde durch säulenehromatographische Untersuchungen auf Sephadex G 50 weitgehend ausgeschlossen.
    Notes: Summary The extraction and further purification of a lipolytic substance from hog pituitaries (Fraction H) are reported. This substance has physico-chemical properties identical with Fraction H extracted from pituitaries of pigs byRudman et al. Further purification was achieved by Sephadex-chromatographie. The lipolytic activity in the rabbit was augmented in vitro to 0.1 Μg/ml and in vivo to 63 Μg as minimal effective dose. A contamination with ACTH could be excluded by chromatography on Sephadex G 50.
