title: [Plasma lipids, insulin, C-peptide, and glucagon levels in cirrhosis: personal observations].
abstract: The authors report preliminary data on the behavior of some lipid fractions in cirrhosis of the liver and correlate them with the changes in the insulin, glucagon and C-peptide levels. Elevated FFA (Free Fatty Acids) and normal cholesterol, triglyceride and total lipid values indicate a prevalent insulin induced effect and a reduction of liver metabolism of these fractions. This hypothesis is supported by the fact that L-carnitine, which reestablishes the carnitine-dependent intracellular transport system, reduces the levels of all the lipid fractions studied. The normal C-peptide values in these patients with liver cirrhosis show that hyperinsulinemia is caused by impaired metabolism of this hormone and not by hyperincretion. This hyperinsulinemia seems to react positively to the improvement of the intracellular transport systems. A fall in the hyperglucagonemia follows the decreased hyperinsulinemia leading to a hormone balance with lower values and a consequent reduction of the hormonal stimuli on the lipid metabolism. The possibility of administering drugs, which can act on the metabolic pathways responsible for the high FFA plasma levels, which seem to play a role in the physiopathology of encephalopathies and hepatic coma is clinically interesting.
