Lymphocyte subpopulations were studied in the peripheral blood, lymph nodes, and spleens in a group of 17 patients with untreated Hodgkin's disease. In 12 of 15 cases, diminished absolute levels of T-lymphocytes in the peripheral blood were found; however, this was correlated with total lymphopenia. No direct relationship between "T-lymphopenia" and diminished cellular immunity, as measured by phytohemagglutinin and pokeweed mitogen blast transformation, and delayed cutaneous hypersensitivity was demonstrated. In eight lymph nodes involved histologically by Hodgkin's disease, a preponderance of T-lymphocytes was found when compared with a group of seven hyperplastic nodes (78.2 +/- 8.9% versus 54.5 +/- 11.0%, P is less than 0.01). These latter data appear to be consistent with the hypothesis that the pathogenesis of Hodgkin's disease involves a cell-mediated immune response to a neoplastic (antigenic) element.

To determine the frequency and clinical characteristics of infection with Coccidioides immitis in immunosuppressed patients at Stanford University Hospital, clinical records of 14 years were examined. Thirteen cases met the diagnostic criteria. Half had Hodgkin's disease. In six the infection was disseminated; five of the six died early in the course of their infectious illness, frequently without diagnosis. Conclusions include: 1. The occurrence of coccidioidomycosis in immunosuppressed patients seen at institutions in or adjacent to the endemic area is not as rare as the literature suggests. 2. Dissemination is frequently explosive and the radiographic appearance of pulmonary involvement may appear late. Widespread pulmonary dissemination may occur within 24 hours after a negative x-ray. 3. Although the skin test loses its diagnostic value, the serology remains valid. Thus immunosuppressed patients with febrile illnesses (with or without radiographically evident pulmonary involvement) who have a history of travel to an endemic area should have serological examinations. 4. Lymphocytopenia correlates with risk of dissemination of coccidioidomycosis. 5. The administration of immunsuppressive chemotherapy correlates with such risk while radiotherapy and the malignant or non-malignant nature of the disease do not.

In vitro cellular immunocompetence was investigated on 35 patients with Hodgkin's disease by studying their in vitro lymphocyte responsiveness to full range stimulation achieved by a spectrum of phytohemagglutinin concentrations. When compared to the normal lymphocyte profile elicited from 35 control subjects, the Hodgkin's patterns of response enabled the identification of a quantifiable lymphocyte defect present in most patients regardless of their clinical status. Increasing severity of this defect was found with progression of the disease and was most pronounced in patients with skin anergy and absolute lymphopenia. The marked abnormality observed in patients restudied after intensive therapy returned towards normal in patients achieving a long lasting, unmaintained complete remission. The data suggest the early presence of an intrinsic functional lymphocyte defect, increasing severity of which may lead to progressive immunoincompetence, reflected to vitro by imparied lymphocyte responsiveness and in vivo by skin anergy and ultimately lymphopenia.

Tumor involvement of the bone marrow in patients with Hodgkin's disease may be suspected in the presence of other manifestations of advanced disease such as fever, lymphopenia, hypoalbuminemia, mixed cellular histologic type, or Stage III or IV disease by other clinical parameters. It occurs more frequently in the older age groups. When anemia, leucopenia, and/or thrombocytopenia are present and are unrelated to recent bone marrow suppressant chemotherapy, marrow involvement is likely to be present. Bone marrow examination, done by multiple trephine biopsies, provides an adequate sampling of tissue and results in a high incidence of detection of involvement by Hodgkin's disease. This manifestation of Hodgkin's disease is associated with a relatively short survival. Aggressive combination chemotherapy is necessary to produce a significant remission.

Forty-one patients with Hodgkin's disease staged as IA(4), IIA/B(4/6) IIIA/B(6/9) and IVA/B(3/9) who had had radiotherapy (subtotal nodal irradiation (STNI) or total nodal irradiation (TNI), or combined one (STNI/TNI plus chemotherapy MOPP or MOPP/ABVD) have been enrolled consequently and randomized to receive thymic hormone (17 patients) or pentapeptide treatment (14 patients) for 3-6 months at the end of the therapeutic regimens. In all patients severe immunodeficiency evaluated either as leukopenia (WBC less than 4000/mm3) or lymphocytopenia (lymphocytes less than 1500/mm3) or CD3 and CD2 cell reduction, or imbalance of helper/suppressor (H/S) ratio have been documented before starting thymic therapy. Different results by immunorestorative therapy have been registered according to the entity of immunodeficiency. In fact in the group of 15 patients with severe lymphopenia (lymphocytes less than 1000/mm3) either the thymic hormone or the synthetic drug produced a significant increase of all subsets examined: CD3-CD2-CD4-CD8 without or with minimal influence on H/S ratio, due to the increase of absolute lymphocytes count. In the remaining patients with mild or no lymphopenia the two drugs resulted ineffective on T cells. Comparing the overall group of patients who received thymic therapy with a control group of patients who did not, an advantage in terms of recruitment of T cell compartment has been observed in the former group when mean values are compared. According to the clinical impact of the immunotherapy with thymic substances on these patients, a significant decrease in incidence of herpes virus infection (HVI) has been observed in patients who had had thymic therapy compared with the incidence of HVI in the control group (18% versus 53.8%).(ABSTRACT TRUNCATED AT 250 WORDS)

Bone marrow biopsies and smears were examined from 70 patients with acquired immunodeficiency syndrome (AIDS) or AIDS related conditions: 32 patients with AIDS; 9, at risk, group patients with B-cell lymphoma; 22 patients with AIDS related complex (ARC) and 7, at risk, group patients with idiopathic thrombocytopenic purpura (ITP). The first three groups showed similarity with respect to frequency of nonspecific findings: hypo and hypercellularity, marrow damage, lymphoid aggregates, histiocytosis, plasmacytosis and features of myelodysplasia. AFB and fungal organisms were present in the biopsies of 17 per cent of AIDS and 18 per cent of ARC patients. The organisms were associated with bone marrow granulomas or histiocytosis, peripheral lymphopenia and anemia. Only one out of 9 biopsies in patients with previous diagnoses of lymphoma showed involvement of the marrow. One case each of Hodgkin's disease and non-Hodgkin's lymphoma were discovered incidentally among the 22 biopsies from ARC patients without a previous diagnosis of lymphoma. Except for those presenting with ITP alone, bone marrow changes are similar in patients with AIDS and AIDS related conditions.

A retrospective study of pre-treatment bone marrow biopsies was undertaken to examine the value of bone marrow staging in Hodgkin's Disease. Bone marrow biopsy revealed infiltration in 40 out of 613 cases, (6.5%). These patients were not significantly different from stage 4 patients without marrow involvement with regard to age, sex, anaemia or survival. Peripheral blood lymphopenia and lymphocyte depleted histopathological type were more common in patients with marrow involvement. Bone marrow biopsy altered individual patient management in less than 1% of 613 patients and can no longer be recommended as part of the routine staging in Hodgkin's Disease.

Systemic lupus erythematosus (SLE) was diagnosed in 31 black Zimbabweans over a six year period. Renal involvement (71%) was more common and photosensitivity (16%) and serositis (23%) less common than in the United States. Lymphopenia (48%) was the commonest haematological abnormality. Unusual complications included subarachnoid haemorrhage, cardiac rhythm disturbance, portal and superior mesenteric vein thrombosis, and a non-Hodgkin lymphoma. Tuberculosis was a common differential diagnosis that was difficult to exclude. Nine patients (29%) died within one year of diagnosis. SLE is being recognised more commonly in Zimbabwe.

The distribution of T-lymphocyte subsets in patients with Hodgkin's disease (HD) at diagnosis and in those disease-free off-therapy for over 5 years, was assessed with OKT monoclonal antibodies. In patients at diagnosis, T-cell subsets appeared substantially balanced with only a moderate reduction in the proportion and absolute number of OKT4 (helper/inducer) positive cells, suggesting that the lymphopenia, constantly associated with HD at diagnosis, is mainly due to a reduction in the helper/inducer T-cell subpopulation. In patients off-therapy, a reduced proportion, but normal absolute number, of OKT4+ cells was constantly accompanied by a significant increase in the proportion and absolute number of OKT8+ cells, compared with patients at diagnosis and normal controls (40% +/- 11 versus 24% +/- 7 and versus 23 +/- 6, respectively). Consequently the OKT4/OKT8 ratio, normal or near normal in patients at diagnosis (1.70 versus 2.00), was significantly reduced in patients off-therapy (0.78 versus 2.00, P less than 0.001). These data suggest that in patients with HD at diagnosis, T-cell subpopulations are substantially normal, while a significant abnormality was observed in patients with HD off-therapy and potentially "cured." Further investigations will better elucidate these findings probably related to the cytotoxic radiotherapy and chemotherapy.

A quantitative analysis of leukocytes in the peripheral blood of 16 patients with lymphogranulomatosis X revealed the following findings: The number of total leukocytes, monocytes, neutrophils, and eosinophils varied considerably and showed no clear common tendency. Blood basophils were found to be clearly increased with a mean value of 0.17 +/- 0.18 X 10(9)/1 as compared to 55 normal donors (0.04 +/- 0.01 X 10(9)/1). Lymphocyte counts were within the normal range. Lymphopenia was seen in 2 patients. Lymphocytes with azure granules which encompass T-suppressors were found to exceed normal values by a factor of 15. In 14 cases a variable number of hyperbasophil cells were present. Lymphogranulomatosis X seems to present with a characteristic blood picture which might be of diagnostic aid.
