Incubation in vitro of lymphocytes from patients with Hodgkin's disease with 40 mug per milliliter of levamisole resulted in a rise in the number of E-rosette-forming cells from 33.6 +/- 12.5 per cent (mean +/- S.D.) to 56.7 +/- 14.6 per cent. The drug had no effect on normal lymphocytes. Ten patients with Hodgkin's disease treated six months previously with levamisole were restudied. The positive skin tests to PPD, candida and mumps persisted. However, the E-rosette-forming cells decreased to the pretreatment levels (34.7 +/- 6.4 per cent). Readministration of 150 mg of levamisole for three days raised the number of E-rosette-forming cells to 54.1 +/- 5.6 per cent. This effect was observed for at least two months. However, the drug had no effect in vitro as long as the in vivo effect persisted. These results demonstrate a clear immunologic effect of levamisole in Hodgkin's disease and indicate that the low number of E-rosette-forming cells is not due to a real T-cell depletion.

Six children suffering from Hodgkin's disease (HD), in different stages and free from chemo- and radiotherapy from at least four weeks, were treated with transfer factor (TF). PPD skin test, PHA-responsiveness, E-rosettes, B-lymphocytes were checked before TF therapy, after 6 and 9 TF doses and compared to the data at the onset of the disease. Two children with HD who did not receive TF, were examined as controls. PPD skin tests, PHA-responsiveness, E-rosettes did not ameliorate following TF treatment, while it has been noticed an increase in B-lymphocytes, both in percentage and absolute number. The Authors conclude that TF might have induced a slight B lymphoproliferation.

Adoptive transfer of delayed hypersensitivity skin test response to tuberculin with 'immune' RNA extracted from the sensitized lymphocytes of a healthy subject or a patient with Hodgkin's disease was successfully demonstrated in previously non-sensitive patients with neoplastic diseases including Hodgkin's disease. 'Non-immune' RNA obtained from non-sensitive man, on the other hand, failed to transfer PPD skin reactivity in non-sensitive recipients. 'Immune' RNA-mediated PPD skin test response remained positive for a considerable period of time, indicating that the effect of 'immune' RNA is systemically active. 'Immune' RNA was found to be RNase-sensitive but DNase-resistant. In vitro adoptive transfer of delayed hypersensitivity with 'immune' RNA, as assayed by lymphocyte transformation test, was unsuccessful.

In vitro lymphocyte response to phytohemagglutinins (PHA), concavalin A (Con A), and pokeweed mitogen (PW) was evaluated in untreated and treated patients with Hodgkin's disease (HD). The responding capacity to PHA was depressed, though not constantly, in the untreated patients compared with the response to lymphocytes from normal individuals. The depression was more evident, at group level, when the cells were stimulated with suboptimal concentrations of PHA. Radiotherapy constantly induced a strong decrease or a complete loss of the responding capacity of the cells which persisted at low levels for many months. Some years after the initial course of treatment, the response was clearly depressed, but it was better in patients in remission than during relapse. Splenectomy did not affect the responding capacity of the cells. The depressive effect induced by chemotherapy was apparently less marked and persistent than that of radiation. Con A- and PW-induced lymphocyte transformation usually paralleled the PHA-induced response. The depressed response to PHA was not due to an inhibitory activity of HD serum. Washed HD lymphocytes in fetal calf serum were not stimulated better than in autologous plasma, nor were HD sera able to depress the response of normal lymphocytes to PHA, Con A, PW, and PPD. Supernatants from HD lymphocytes cultured for 24 h without any stimulant, and extracts of these cells were also unable to affect the response of normal lymphocytes to PHA.

To detect the changes of cellular immunity which occur at the same time as the pathological process and to find out the possible biologic indicators with prognostic value, a study was carried out on 140 patients with Hodgkin's disease (HD) in different clinical periods: onset, under therapy (cytostatics and/or irradiations), remission, after splenectomy and under immunotherapy. The study of cellular immunity included the determination of lymphocytes subpopulations by the rosette tests and their functional estimation by tests of blastic transformation to mitogens and antigens. Though the values obtained presented a wide dispersion, the rosette tests showed variations in correlation with the clinical stage, therefore with the severity of disease. It was observed that therapy and splenectomy change the cellular immunity tests. The only test with a certain prognostic value was found to be the in vitro lymphocyte response to PPD which became positive after therapy, particularly in the group of patients who showed good response to treatment. A dynamic follow-up of the cellular immunity tests might give an indication on the mechanisms of production of the immune deficit in HD.

Serum levels of immunosuppressive acidic protein (IAP) in 105 patients with hematopoietic malignancies, there were 12 cases of acute myeloblastic leukemia, 1 acute monocytic leukemia, 13 myelomonocytic leukemia, 4 acute promyelocytic leukemia, 26 chronic myelogenous leukemia, 22 non-Hodgkin's lymphoma, 5 Hodgkin's disease, 6 adult T-cell leukemia, 5 acute lymphoblastic leukemia, 3 chronic lymphocytic leukemia, and 8 multiple myeloma. High levels of serum IAP were detected in all of the patients except chronic phase of CML, malignant lymphoma in stage I and II, and multiple myeloma. In the cases of malignant lymphoma, serum IAP levels in stage III and IV were higher with statistical significance (p less than 0.01) than those in stage I and II. Serum IAP levels in the patients with CML in blastic crisis were higher than in the chronic phase, so serum IAP levels are useful as one diagnostic parameters in blastic crisis. However, in patients with ANLL in relapse, serum IAP levels showed normal values. Serum IAP levels paralleled those of acute phase reactants such as alpha 1-acid glycoprotein , C-reactive protein, alpha 2-globulin, and alpha 1-antitrypsin, and had inverse correlations with PPD and PHA skin test.

Immunological functions of 9 non-splenectomized and 8 splenectomized patients with Hodgkin's disease were studied before and after treatment. The two groups compared well with regard to age, clinical and immunological findings at diagnosis and observation time. When retested, all patients had enjoyed an unmaintained complete remission for 2 to 5 years following total nodal radiotherapy. After therapy, total lymphocyte and T-lymphocyte counts decreased in non-splenectomized patients but remained unchanged in splenectomized patients. The blood lymphocyte DNA synthesis after activation by concanavalin A or pokeweed mitogen persisted at the same low level after treatment. The delayed skin hypersensitivity and the lymphocyte activation by PPD antigen were restored in several patients in both groups. The IgM concentration decreased after therapy independent of splenectomy. The IgA level was low in non-splenectomized patients. Splenectomy seems to protect from the therapy-induced lymphocytopenia. No alterations of immunoglobulins and blood lymphocyte functions could be ascribed to splenectomy.

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.

Spontaneous and mitogen induced blood lymphocyte DNA synthesis was studied in relation to weight and tumor involvement of the spleen in 33 untreated patients with Hodgkin's Disease. Splenic tumor involvement was found in 14 patients. In this group there was a strong inverse correlation between spleen weight and lymphocyte DNA synthesis induced by PWM, ConA and PPD. In patients with uninvolved spleens the spontaneous blood lymphocyte DNA synthesis increased with spleen weight. No correlation with the mitogen response was observed in this group.

One hundred and twenty seven consecutive and previously untreated patients with Hodgkin's disease (HD) (mean age 47 years) from the Stockholm area admitted to Radiumhemmet, Karolinska Hospital, were studied. The age-matched control group consisted of 167 healthy adults. Incorporation of [14C]-dT was measured on Day 1 in unstimulated monocyte-depleted lymphocyte cultures, and on Day 3 in cultures activated by PWM, ConA and PPD, T and B cells were enumerated by surface markers. The patients had significantly decreased relative and total T-cell counts, and the lymphocyte DNA synthesis induced by mitogens and PPD was severely impaired, whilst the spontaneous DNA synthesis was significantly greater than in controls. At follow-up (mean 4 years) 40 patients have died. Deceased patients showed greater spontaneous lymphocyte activation and less response to mitogen and antigen stimulation than the survivors. The 5-year survival of patients with severe lymphocyte impairment was 20%, compared to 80% for the remainder. The lymphocyte tests added prognostic information to that from clinical staging. Disregarding the lack of knowledge of the mechanisms underlying the lymphocyte impairment, we suggest that these relatively simple immunological tests should be included in the clinical evaluation of HD patients and would guide the choice of therapy.
