Between October 1991 and May 1994, 42 patients were treated with cyclophosphamide, thiotepa, and total body irradiation followed by an allogeneic transplantation of marrow depleted of T cells with soybean agglutinin and E-rosetting. Patients included in this study had acute myelogenous leukemia (13), chronic myelogenous leukemia (12), acute lymphocytic leukemia (nine), Hodgkin's disease or non-Hodgkin's lymphoma (four), multiple myeloma (three), or myelodysplastic syndrome (one). The mean age was 34 (range 8 to 51 years). Nineteen patients had a matched sibling donor and 18 received marrow from 6/6 matched unrelated donors while five received transplants from unrelated donors disparate at one DR locus (5/6 match). Time to granulocyte engraftment (AGC > or = 500/mm3) occurred at a mean of 16.5 days for related and 11.4 days for unrelated transplant recipients, and was related to the increased use of G-CSF in the unrelated population. There was no correlation with number of mononuclear cells, T cells, or CD34-positive cells infused, the rate of engraftment or the incidence of transplant complications. Multivariate analysis determined that G-CSF administration and a diagnosis other than ALL were the only factors associated with a faster rate of engraftment. Patients receiving unrelated donor transplants, those with ALL, or those who had a low T cell number infused (< or = 8.0 x 10(3) cells/kg) experienced delayed hospital discharge. The regimen resulted in excellent rates of engraftment (95.2%) with only one failure to engraft and one graft rejection. The incidence of grade III-IV acute graft-versus-host disease was 0% with sibling and 26.1% with unrelated donors. There were no cases of veno-occlusive disease. Fifty percent of patients are alive with a mean follow-up of 26.4 months. We conclude that this regimen is well tolerated and results in excellent engraftment with a low incidence of severe graft-versus-host disease and few therapy-related toxicities.

In our BMT Unit, we have observed a high frequency of skin rash associated with fever and other clinical findings during engraftment of autologous BM and/or PBSC. Thirty patients with breast cancer and 12 patients with Hodgkin's or non-Hodgkin's lymphoma, treated with the same regimen, were analyzed retrospectively or prospectively to characterize the clinical syndrome, its frequency, and its clinical course, as well as to define the factors affecting its incidence. In patients developing skin rash, the median and range for time to onset of skin rash and for time to increase in WBC after reinfusion of stem cells were identical (8 days, range 5-13) and did not differ significantly (P = 0.533). Twenty-three patients (55%) had skin rash, 18 patients had fever. Other, less frequent manifestations include platelet transfusion refractoriness (PTR), diarrhea, diffuse alveolar hemorrhage, and autoimmune thrombocytopenia or hemolytic anemia. A higher proportion of breast cancer patients developed the syndrome in comparison to lymphoma patients (67% vs 25%, P = 0.051). Acute GVHD grade I-II was established histologically in six patients with the syndrome. Comparison of the incidence of the syndrome by different variables using Fisher's exact test revealed significance for disease category (P = 0.02) and number of previous treatment regimens (P = 0.002) as predictive factors for developing the autoaggression syndrome. In other words, patients with breast cancer and those with only one previous treatment regimen were more likely to develop the syndrome. This study suggests that an autoaggression GVHD-like syndrome accompanies the early phase of autologous engraftment and that a higher frequency of the syndrome might be seen in breast cancer patients undergoing high-dose chemotherapy and autologous stem cell transplantation.

CD30 is a member of the tumor necrosis factor (TNF) receptor family, originally described as a marker for Hodgkin and Reed-Sternberg cells in Hodgkin's disease, which has been found to be preferentially expressed by T cells producing Th2-type cytokines. The presence of CD30 expression was assessed by both immunohistochemistry and reverse transcriptase-polymerase chain reaction in the target organs of patients with Th1- or Th2-dominated disorders. CD30 expression was found in neither the gut of patients with Crohn's disease nor in the gastric antrum of Helicobacter pylori-infected patients, where there was high interferon-gamma (IFN-gamma) expression. In contrast, high CD30 expression in the apparent absence of IFN-gamma expression was observed in the skin of patients with systemic sclerosis or chronic graft versus host disease (GVHD), which can be considered Th2-dominated disorders. Moreover, high levels of soluble CD30 were found in the serum of both systemic sclerosis and GVHD patients but not in the serum of patients suffering from multiple sclerosis, a Th1-dominated disorder. Thus, CD30 expression appears to be preferentially associated with Th2-type responses not only in vitro but also in vivo.

A 32-year-old male received an allogeneic peripheral blood stem cell transplant (alloPBSCT) for myelodysplasia from his one HLA-A antigen mismatched brother. He is alive with trilineage engraftment and without active GVHD 200 days after transplant. In July 1986 he underwent orthotopic cardiac transplantation for viral cardiomyopathy and has received continuous immunosuppressive therapy. A post-transplant lymphoproliferative disorder with Hodgkin-like histopathology was diagnosed in August 1993 and was successfully treated with four cycles of MOPP chemotherapy. Due to persistent pancytopenia he underwent a bone marrow aspiration and biopsy in May 1996 which revealed monosomy 7 and morphologic changes compatible with myelodysplasia. This is the first report of a cardiac transplant recipient receiving an allogeneic hematopoietic stem cell transplant.

lnterleukin-2 (IL-2) is known to cause xerostomia and skin manifestations similar to graft-versus-host disease (GVHD). We therefore evaluated major salivary gland function in patients with hematological malignancies treated with IL-2 and interferon-alpha (IFN-alpha) after ABSCT. Eleven patients (seven male, four female) of median age 40 (24-47) were evaluated, seven with non-Hodgkin lymphoma (NHL); one with Hodgkin's disease (HD) and three with acute myelogenous leukemia (AML). Parotid and submandibular salivary gland function was assessed before, during and after IL-2/IFN-alpha administration by evaluation of the salivary flow rate and the composition of secreted saliva. Significant reductions in both the resting and stimulated parotid and submandibular salivary flow rates were observed during IL-2/IFN-alpha immunotherapy compared with the pre- and post-therapy values (P < 0.01), while no hyposalivation was observed in the control patients who underwent ABSCT and did not received IL-2. Sialochemical evaluation revealed a significant increase in potassium concentration (24.4+/-0.6 mEq/l to 28.9+/-1.4 mEq/l) and a significant decrease in sodium concentration (6.7+/-2.1 mEq/l to 3.3+/-1.0 mEq/l) (P < 0.05) in the stimulated parotid gland saliva secreted during IL-2/IFN-alpha administration. Salivary protein concentrations were not altered by the IL-2/IFN-alpha immunotherapy. Similar changes were previously observed in mice and humans with chronic GVHD. We conclude that IL-2 immunotherapy induces major salivary gland dysfunction in humans, similar to our previous observations in patients with chronic GVHD, which may indicate similar pathophysiologic mechanisms.

The relative benefit of allogeneic bone marrow transplantation (alloBMT) vs autologous BMT (autoBMT) for patients with relapsed or refractory Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) remains uncertain. Toxicity from graft-versus-host disease (GVHD) may diminish the potential benefits both of graft-versus-tumor activity and of receiving uncontaminated donor marrow stem cells. From 1987 to 1995, 27 adults (ages 18-60 years; median 36) underwent alloBMT for lymphoma after failure of standard chemotherapy. Twenty-one had NHL and six had HD (nodular sclerosis). Thirteen patients had primary refractory disease or chemotherapy-resistant relapses; two of these had relapsed after autoBMT. Three patients had untested relapses (one of them had relapsed after autoBMT), and 11 had chemotherapy-sensitive relapses. Twenty-four received HLA-matched bone marrow from a sibling (one twin); three received haploidentical marrow cells. Nine (33%) died from lymphoma. Eleven (41%) died of treatment-related causes. Opportunistic infections were a substantial problem leading to eight of these deaths (30%). Six patients (22%) survive free of lymphoma 17-70 months post-BMT (median, 56 months); four had had sensitive relapses, one had had a resistant relapse, and one had had nontested relapse. Three have chronic GVHD (limited in one; extensive in two). One HD patient who had relapsed after autoBMT remains in remission 19 months after alloBMT. No therapy-related myelodysplasia has been observed. We conclude that alloBMT has substantial morbidity in heavily pretreated lymphoma patients due to acute toxicity, infections and GVHD. However, 22% of our HD/NHL patients have had long-term disease-free survival.

The Bone Marrow Transplantation Program in Belarus was founded in 1992, and in 1993, a Bone Marrow Transplantation Centre was created in Minsk. From February 1994 to April 1996, 19 allogeneic bone marrow, 16 autologous bone marrow and 10 autologous peripheral blood stem cell transplantations were performed. Reasons for transplantation included chronic myeloid leukemia, multiple myeloma, severe aplastic anemia, acute myeloid leukemia, acute lymphoblastic leukemia, progressive myelofibrosis, Hodgkin's disease, non-Hodgkin's lymphoma, and neuroblastoma. Among the patients were two liquidators involved in the Chernobyl cleanup activity, both of whom underwent allogeneic bone marrow transplantation. A variety of ablative preparative regimens were used, and blood progenitor cells were mobilized by treatment with Cytoxan and granulocyte colony-stimulating factor. Therapy-related deaths resulted from graft-versus-host disease, septic shock, veno-occlusive disease bleeding and intestinal pulmonary fibrosis. Because the transplantation procedures were carried out on people who continued to be exposed to low-level irradiation, the post-transplantation period included a conservative strategy for prevention of graft-versus-host disease. There was nothing unusual about the post-transplantation period, although uncertainty about the continuing radiation dose should be taken into account when interpreting these data.

The immune reactivity of allogeneic lymphocytes plays a major role in control of leukemia after bone marrow transplantation. We studies the efficacy of donor leukocyte transfusion (DLT) on acute and chronic leukemia in relapse after bone marrow transplantation in Japan. Sixty nine patients with chronic myelocytic leukemia (N = 17), acute lymphoblastic leukemia (N = 25), acute myelocytic leukemia (N = 26), myelodysplastic syndrome (N = 5), non-Hodgkin lymphoma (N = 2) and rhabdomyosarcoma (N = 1) were treated with transfusions of donor lymphocytes. Therapeutic effects were induced by donor leukocyte transfusion in 20 patients (29%) including 3 patients out of 4 (75%) with CML in cytogenetic and chronic phase relapse, 4 out of 5 (80%) patients with myelodysplastic syndrome, 3 out of 13 (23%) patients with CML in transformed phase, 5 out of 25 (20%) patients with acute myelocytic leukemia, and 4 out of 20 (20%) patients with acute lymphoblasic leukemia. Twenty two patients (30%) developed acute GVHD (> or = 2) and 6 out of 73 (8.2%) patients developed fatal GVHD after donor leukocyte transfusion. Patients relapsed within 6 months after marrow transplantation had a probability of having severe acute GVHD (> or = 2) after DLT. Fourteen out of 24 (58%) patients with GVL response were re-relapsed thereafter. Minimal dose of donor leukocytes infused in successfully treated 9 patients without cytoreductive therapy was 2 x 10(7)/kg in total and minimal dose of that in 6 patients with fatal GVHD was 7 x 10(7)/kg in total. The anti-leukemia effect of donor leukocyte transfusion was strongest against CML in cytogenetic and chronic phase and induce a durable complete remission.

Acute bleeding after bone marrow transplantation (BMT) was investigated in 1,402 patients receiving transplants at Johns Hopkins Hospital between January 1, 1986 and June 30, 1995. Bleeding categorization was based on daily scores of intensity used by the blood transfusion service. Moderate and severe episodes were analyzed for bleeding sites. Analysis of the cause of death and the interval of the bleeding episode to outcome endpoints was recorded. Survival estimates were computed for 1,353 BMT patients. The overall incidence was 34%. Minor bleeding was seen in 10.6%, moderate bleeding was seen in 11.3%, and severe bleeding was seen in 12% of all patients. Fourteen percent of patients had moderate or severe gastrointestinal hemorrhage, 6.4% had moderate or severe hemorrhagic cystitis, 2.8% had pulmonary hemorrhage, and 2% had intracranial hemorrhage. Sixty-one percent had 1 bleeding site and 34.4% had more than 1 site. Moderate and severe bleeding was more prevalent in allogeneic (31%) and unrelated patients (62.5%) compared with autologous patients (18.5%). Significant distribution of incidence was found among the different diagnoses, but not by disease status in acute myeloid leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, Hodgkin's disease, and non-Hodgkin's lymphoma. Bleeding was associated with significantly reduced survival in allogeneic, autologous, and unrelated BMT and in each disease category except multiple myeloma. Survival was correlated with the bleeding intensity, bleeding site, and the number of sites. Although close temporal association was evident to mortality, bleeding was recorded as the cause of death in only the minority of cases compared with other toxicities after BMT (graft-versus-host disease, infections, and preparative regimen toxicity). Acute bleeding is a common complication after BMT that is profoundly associated with morbidity and mortality. Although bleeding was not a direct cause of death in the majority of cases, it has a potential prognostic implication as a predictor of poor outcome in clinical assessment of patients after BMT.

Cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4, CD152) is a molecule expressed on in vitro activated T cells. CTLA-4 shares important sequence homology with CD28 and binds to the same ligands, CD80 (B7-1) and CD86 (B7-2). CTLA-4 probably functions as a negative regulator of T lymphocyte activation in the mouse, although this remains to be proven for human T lymphocytes. We have developed new monoclonal antibodies against human CTLA-4 and have investigated the in situ expression of CTLA-4 in a wide variety of normal and pathological human tissues expressing CD80 and CD86. As revealed in this study, CTLA-4 is expressed on thymocytes in thymic medulla, on a subset of CD4+ T lymphocytes in germinal centers of follicular hyperplasia, on T cells, mainly CD8+, infiltrating skin affected by graft-versus-host disease, and on T cells, mainly CD4+, infiltrating Hodgkin's disease lesions. In immunoelectron microscopy, CTLA-4 was found on the plasma membrane as well as in the hyaloplasm and cytoplasmic vesicles, in agreement with its pattern of expression on in vitro activated T cells. Interestingly, no or at most scarce expression of CTLA-4 was found in granulomatous lymph nodes, T-cell-mediated inflammatory diseases, or non-Hodgkin's lymphomas, regardless of their expression of CD80 or CD86. Thus, expression of CTLA-4 appears to be induced in selective pathological conditions in vivo. The pathways leading to selective induction of CTLA-4 and its role in the pathophysiology of these conditions need to be further investigated.
