    Abstract:
    Patients suffering from lymphogranulomatosis were studied with respect to cellular immune deficiencies. For this purpose, mononuclear cells from venous blood were separated and subjected to analysis of lymphocyte markers. T-lymphocytes were enumerated by means of the sheep erythrocyte (SE) rosette test. T cell subpopulations were determined using enzyme cytochemical staining for dipeptidyl peptidase IV (DP IV) and unspecific acid alphanaphthylacetate esterase (ANAE). In 18 patients with M. Hodgkin a significant reduction in the T lymphocyte count in peripheral blood was found. This T cell defect is due to a selective decrease in the TM-subpopulation as identified by enzyme cytochemical markers DP IV and ANAE (focal reaction). From these results it is concluded that patients with lymphogranulomatosis have characteristic abnormalities in the immune system in the sense of a disturbed equilibrium of immune regulatory cells.
