lipid metabolism and metabolic syndrome

Previous and current research

Turnover measurements
Initially turnover measurements of triglyceride-rich lipoproteins have been carried out in non-diabetic and diabetic persons. The significance of the VLDL overproduction could be shown. Later on the turnover of apolipoproteins B and A has been measured using stable isotopes. With this method interesting data have been found in patients with familial defective apolipoprotein B and with the metabolic syndrome.

Familial combined hyperlipidemia
Within this disease, a family study was performed. It was shown that elevated triglyceride levels are atherogenic.

Metabolic syndrome
In a family study the heredity of the syndrome and the role of the insulin resistence have been demonstrated.

Comparison of different methods of LDL apheresis

Our group has participated in the introduction of the DALI method. Moreover measurements of the coagulation system and of the effectiveness in different LDL apheresis methods were performed. Recently a study evaluating a new whole-blood method (Liposorber D) was carried out. In the future previous studies on the reaction of blood cells to apheresis will be continued.

Drug studies in metabolic patients
We took part in several studies examining the effects of lipid-lowering and antidiabetic drugs (fibrates, statins, nicotinic acid, ezetimibe, DPIV inhibitor). Moreover we participate in a study in which somatostatin is being used in patients with diabetic retinopathy.
