title: [Different forms of hyperlipoproteinemia in diabetics (author's transl)].
abstract: Plasma lipoprotein patterns currently employed in attempts to identify different forms of hyperlipoproteinemia have been investigated in 113 hospitalized diabetics. For classification two methods have been compared: The first is based on lipid electrophoresis pattern in agarose gel coupled with the measurement of triglycerides and cholesterol. The second is based on plasma lipoprotein pattern obtained by separation of lipoproteins on cellulose acetate and following densitometry combined with estimation of cholesterol and beta-cholesterol and triglycerides in plasma. It could be demonstrated, that the results obtained in agarose system are not convertible to data obtained with the method for quantifying lipoproteins. By quantitative analysis only 4 p.c. of diabetics had type IIa, 4 p.c. type V, the others type IIb or IV. Graphic plots and calculated concentrations of lipoproteins gave differences in lipoprotein profiles between compensated and acidotic diabetics. In diabetes stage 1 most values are in the normal range, in stage 2 prebetalipoproteins increase and betalipoproteins decrease. In some case betalipoproteins are elevated and prebetalipoproteins diminished. In stage 3 with metabolic acidosis we observed an altered lipoprotein profile with confluence of beta- and prebeta-peak. The calculated concentration profile was also different from the others and revealed no certain quantitative information described for other electropherograms containing alpha, beta- and prebeta-bands. This phenomenon was frequently observed in patients with acute viral hepatitis and severe chronic liver disease. The pattern in diabetics is representative for patients with an excess of plasma lipids (the 2.5 fold of normal values in the mean). It is characterised as a broad beta band on the electropherogram similar to type III pattern. Presence of beta migrating lipoproteins in the ultracentrifugal supernatand fraction of d = 1006 could not be demonstrated.
