[The clinical value of unspecific humoral immune parameters. Attempt at an immunogram. 1. Quantitative determination of IgG, IgM, IgA and IgD and demonstration of antibodies against cell and tissue bound antigens in patients with chronic pyelonephritis].

In the serum of patients with chronic pyelonephritis IgG, IgM, IgA, IgD and autoantibodies against organ- and species-specific renal antigens were determined. Clinical questions concerned relations to the activity of the disease and the renal function. The Ig-mean-values lying within the biological norm could be precised by taking into consideration individual biological boundary titres and relative ratio values. Pictures of tendency led to the estimation that increases of IgG and IgD appear in severely restricted renal function in normal or decreased IgM. Increases may be a criterion of activity in diseases with normal or slightly restricted renal function. IgA determinations remained without any evidence.-- Autoantibodies were found in 32,5%, increased titres were a sign of deteriorated renal function. The apparently given possibility of a humoral immunogramme for the chronic pyelonephritis is discussed, in which case a combination with other test parameters seems to be necessary.
