title: [The diagnostic significance of immunoglobulin determination in chronic liver diseases. I. Differential diagnostic accuracy of immunoglobulin changes and enzyme activities (author's transl)].
abstract: 715 patients with hepatobiliary diseases came for examination, who because of the morphological findings are classified in diagnostic groups. The immunoglobulin measurements of IGG, IGA, IGM were determined and assessed in combination with enzymatic investigations of GOT, GPT, AP and GGTP. Typical group-specific changes were only found in primary biliary liver diseases and toxic cirrhoses of the liver, all acute or chronic inflammatory liver diseases could not be separated and by inference from the final diagnosis showed great errors in classification. Data on the raised mean levels of immunoglobulins in the individual diagnostic groups were demonstrable, but the range limits were so widely scattered that their differential diagnostic valence is of no consequence. Immunoglobulins may appear to be of interest for the observation of the course of liver diseases, but they are unsuitable for diagnostic purposes.
