title: [Concentration of C-peptide and insulin in serum of patients with acute virus hepatitis (author's transl)].
abstract: Intravenous glucose tolerance tests were performed in 10 patients with acute virus hepatitis. The assimilation coefficient of glucose and the level of insulin and C-peptide in serum were determined before and in the course of the glucose tolerance tests. In comparison to healthy normal weight persons C-peptide concentration in patients with acute hepatitis increased twice as high whereas the pattern of insulin secretion did not differ significantly. The higher levels of C-peptide indicate an increase of the beta-cell secretion in acute hepatitis. One could suppose an increased hepatic destruction of insulin in acute hepatitis, because there is no significant difference among the insulin levels. More likely, there is a reactive increase of secretion of the beta-cell due to a reduction of insulin sensitivity and this is indicated much better by C-peptide- than insulin levels because of the longer half live of the the C-peptide molecule.
