[Discriminatory function of serum proteins in liver and biliary tract diseases]

In 104 patients with acute virus hepatitis, chronic hepatitides, cirrhoses, fatty livers and biliary diseases with partial and complete obstructive jaundice, respectively, IgG, IgA, IgD, beta1A- and beta1E-globulin, cholinesterase, total protein, and albumin, in 45 of these patients additionally prealbumin, retinol binding protein, thymol turbidity test were determined as well as an electrophoretic separation of the serum was performed. 11 persons with healthy liver served as control group. According to the results of univariate and multivariate variance analyses with following test of redundance (test for indispensability) and analysis of discriminance with calculations of reclassification IgD, beta1E-globulin and retinol binding protein were identified as not evident or redundant. Electrophoresis and thymol turbidity test give sufficient basis informations and can further be recommended for orienting examinations. Immune globulinogrammes from IgB, IgA and IgM are suitable as so-called mesenchyma tests particularly for controls of the course. Prealbumin and cholinesterase prove to be the most sensitive parameter of synthesis, whereas albumin and beta1A-globulin possess a high prognostic evidence.
