Immune condition in patients with Hodgkin's disease

Abstract

In 40 cases of Hodgkin's disease (24 untreated patients and 16 patients in remission) the immunological humoral and cell-mediated competence was studied using test of hypersensitivity of DNCB and PPD, blastic transformation and the ability of 3H-DNA synthesis in lymphocytes stimulated with PHA and PWM, and in some cases, with PPD. In all patients the concentration of serum immunoglobulins was determined as well. Impairment of immunological reactivity was found in about 40% of patients, on the average, in various stages of the disease and during remissions following treatment with cytostatic agents and radiotherapy. The most frequent abnormality found in 52.5% of cases was impairment of blastic transformation of lymphocytes stimulated with PHA in vitro. In 60% of cases negative results of intradermal test with PPD and in 75% of patients the DNCB test was negative. No correlation could be found between impairment of the immune competence in this disease and the clinical stage and/or type of histological changes in lymph nodes.
