[The effect of polyene phosphatidylcholine administration on lipid metabolism and glucose tolerance in patients with hyperlipoproteinemia IIB].

BACKGROUND

Up to now, clinical and experimental studies have brought only inconsistent data about the effectiveness of polyene phosphatidylcholine (PPC) in treatment of dyslipidemia. The aim of this randomized, double blind study was to verify the effects of the polyene phosphatidylcholine preparation Lipostabil forte R (Rhone-Poulenc-Röhrer, Köln, FRG), given orally in a daily dose 2.7 g for three months to patients with hyperlipoproteinemia type IIB and hypoalfacholesterolemia both on the plasma lipids, lipoproteins, apolipoproteins and the parameters of glucose tolerance.

METHODS AND

RESULTS

Administration of PPC to 30 patients with hyperlipoproteinemia type IIB and hypoalfacholesterolemia led to a significant rise of HDL-cholesterol, HDL3-cholesterol and plasma apolipoprotein A-I concentrations in comparison with the group treated with placebo. At the same time, plasma apolipoprotein B concentration slightly increased. Blood glucose, immunoreactive insulin and non-esterified fatty acid concentrations during the oral glucose tolerance test didn't change significantly after PPC administration.

CONCLUSIONS

It seems PPC could be the appropriate supplement to the treatment of patients with decreased concentrations of HDL-cholesterol and plasma apolipoprotein A-I.
