Abstract
7608 Background: Autologous stem cell transplantation (ASCT) using melphalan 200 mg/m2 is a standard part of inital therapy in younger multiple myeloma (MM) patients (pts). We have previously reported an augmented regimen of melphalan 280 mg/m2 with the cytoprotectant agent amifostine (AF) to try to improve the anti-tumor response without increased mucosal toxicity (The Hematol J 2003; 4[suppl]: S207). We now update our experience with this regimen. Methods: Pts without disease progression and adequate organ function (creatinine clearance at least 60 cc/min) were eligible. Pts were treated as part of phase I-II trials approved by each center’s institutional review board. AF 740 mg/m2 was given IV over 5–15 min 24 hr and 15 min prior to melphalan 280 mg/m2 (infused over 15 min). Blood stem cells were reinfused 24 hrs later. The primary endpoint was response rate at day 100. Regimen-related toxicity using the Seattle criteria, progression-free (PFS) and overall survival (OS) were also assessed. Results: 24 pts were transplanted between 5/99–7/02. Median age was 50 (32–65) yrs; 1 pt had primary amyloidosis; median beta2-microglobulin level at diagnosis was 1.98 (0.88–11.80) mg/L. Prior therapy included VAD in 14, dexamethasone alone in 7 plus other regimens in 7. Day 100 responses compared with with pre-ASCT values included CR in 11, near CR (immunofixation positivity only) in 1, VGPR (greater than 90% reduction in serum M protein) in 3, PR in 5 and stable disease in 3. Maximum grade of mucositis was 2 (5 pts); no grade 3 or 4 toxicity was seen. The median day of ANC recovery to 0.5 x 109/L and median day of last platelet transfusion were 11 (6–16) and 10 (7–32), respectively. 4 received thalidomide (1 briefly), while 1 was treated with maintenance alpha interferon after day 100. Median follow-up is 52 (9–72) mos. 7 pts are alive without progression, including 5 in CR and 2 in PR. 16 have progressed at a median of 15 (7–36) mos post-ASCT. 8 have died from MM (7) or lung cancer (1). The 4 yr actuarial PFS is 28% (95% C.I. 34–76%) and OS 58% (95% C.I.11–47%). Conclusions: 1) Melphalan 280 mg/m2 with AF is well-tolerated; 2) the CR + nCR + VGPR rate of 62% warrants further evaluation, perhaps as part of tandem transplants or in conjuction with novel agents.

Abstract
The immunogenicity of adenovirus (Ad) vectors is enhanced by virus-specific memory immune responses present in most individuals as a result of past exposure to these ubiquitous pathogens. We previously identified the first human T-cell epitope from the major capsid protein hexon, H910-924, and found that it is highly conserved among different Ad serotypes. Memory/effector T-cell responses to H910-924 were detected in 14 of 18 (78%) healthy adults by an interferon-gamma ELISPOT assay. Hexon peptide-specific CD4 T-cell lines were generated from three HLA-typed donors and analyzed using a panel of HLA homozygous B-cell lines and monoclonal antibodies to HLA class II loci. These studies reveal that the hexon epitope is restricted by HLA DP4, a class II allele present in 75% of the population. Analysis of overlapping peptides and peptides with single residue mutations identified a HLA DP4-binding motif. Additionally, antibodies to the hexon peptide were detected in all donor sera by dot blot assay and ELISA. Therefore, most individuals exhibit both memory B- and T-cell responses to this highly conserved epitope on hexon, an obligate component of all Ad vectors, including 'gutted' vectors. These data suggest that current strategies for the use of Ad gene therapy vectors will not evade memory immune responses to Ad.

Abstract
This study was conducted to define a new maximum tolerated dose and the dose-limiting toxicity (DLT) of melphalan and autologous hematopoietic stem cell transplantation (AHSCT) when used with the cytoprotective agent amifostine. Fifty-eight patients with various types of malignancy who were ineligible for higher-priority AHSCT protocols were entered on a phase I study of escalating doses of melphalan beginning at 220 mg/m(2) and advancing by 20 mg/m(2) increments in planned cohorts of 4 to 8 patients until severe regimen-related toxicity (RRT) was encountered. In all patients, amifostine 740 mg/m(2) was given on 2 occasions before the first melphalan dose (ie, 24 hours before and again 15 minutes before). AHSCT was given 24 hours after the first melphalan dose. Melphalan was given in doses up to and including 300 mg/m(2). Hematologic depression was profound, although it was rapidly and equally reversible at all melphalan doses. Although mucosal RRT was substantial, it was not the DLT, and some patients given the highest melphalan doses (ie, 300 mg/m(2)) did not develop mucosal RRT. The DLT was not clearly defined. Cardiac toxicity in the form of atrial fibrillation occurred in 3 of 36 patients treated with melphalan doses >/=280 mg/m(2) and was deemed fatal in 1 patient given melphalan 300 mg/m(2). (Another patient with a known cardiomyopathy was given melphalan 220 mg/m(2) and died as a result of heart failure but did not have atrial fibrillation.) Another patient given melphalan 300 mg/m(2) died of hepatic necrosis. The maximum tolerated dose of melphalan in this setting was thus considered to be 280 mg/m(2), and 27 patients were given this dose without severe RRT. Moreover, 38 patients were evaluable for delayed toxicity related to RRT; none was noted. Tumor responses have been noted at all melphalan doses and in all diagnostic groups, and 21 patients are alive at median day +1121 (range, day +136 to day +1923), including 16 without evidence of disease progression at median day +1075 (range, day +509 to day +1638). Amifostine and AHSCT permit the safe use of melphalan 280 mg/m(2), an apparent increase over the dose of melphalan that can be safely administered with AHSCT but without amifostine. Further studies are needed not only to confirm these findings, but also to define the antitumor efficacy of this regimen. Finally, it may be possible to evaluate additional methods of further dose escalation of melphalan in this setting.

Abstract
High-dose chemotherapy using melphalan (HDMEL) is an important component of many conditioning regimens that are given before autologous hematopoietic stem cell transplantation (AHSCT). In contrast to the situation in myeloma, and to a lesser degree acute leukemia, only a very limited published experience exists with the use of HDMEL conditioning as a single agent in doses requiring AHSCT for lymphoma, both Hodgkin lymphoma (HL) and especially non-Hodgkin lymphoma (NHL). Thus, we report results of treating 26 lymphoma patients (22 with NHL and four with HL) with HDMEL 220-300 mg/m(2) plus amifostine (AF) cytoprotection and AHSCT as part of a phase I-II trial. Median age was 51 years (range 24-62 years); NHL histology was varied, but was aggressive (including transformed from indolent) in 19 patients, indolent in two patients and mantle cell in one. All 26 patients had been extensively treated; 11 were refractory to the immediate prior therapy on protocol entry and two had undergone prior AHSCT. All were deemed ineligible for other, 'first-line' AHSCT regimens. Of these 26 patients, 22 survived to initial tumor evaluation on D +100. At this time, 13 were in complete remission, including four patients who were in second CR before HDMEL+AF+AHSCT. Responses occurred at all HDMEL doses. Currently, seven patients are alive, including five without progression, with a median follow-up in these latter patients of D +1163 (range D +824 to D +1630); one of these patients had a nonmyeloablative allograft as consolidation on D +106. Conversely, 14 patients relapsed or progressed, including five who had previously achieved CR with the AHSCT procedure. Two patients, both with HL, remain alive after progression; one is in CR following salvage radiotherapy. Six patients died due to nonrelapse causes, including two NHL patients who died while in CR. We conclude that HDMEL+AF+AHSCT has significant single-agent activity in relapsed or refractory NHL and HL. This experience may be used as a starting point for subsequent dose escalation of HDMEL (probably with AF) in established combination regimens.

Abstract
Nonmyeloablative pretransplantation conditioning regimens have resulted in durable engraftment of allogeneic hematopoietic stem cells. In contrast to conventional fully myeloablative approaches, nonmyeloablative regimens are associated with a marked reduction of morbidity and mortality in the early posttransplantation period. Consequently, such reduced-intensity transplantation approaches can be used in older and frailer patients who would not tolerate fully ablative regimens. However, it is currently unclear how this radically different transplantation strategy affects immunological reconstitution. To address this important issue, we used T-cell receptor Vbeta spectratype analysis to examine the distribution of complementarity-determining region 3 (CDR3)-size bands as a measure of the complexity of the redeveloping T-cell repertoire. For this study, we evaluated the T-cell repertoire of 9 patients receiving T-cell replete, matched unrelated donor transplants following fully ablative or nonmyeloablative conditioning regimens. All 4 of the myeloablative and 2 of the nonmyeloablative patients received bone marrow, whereas 3 other nonmyeloablative patients received peripheral blood stem cells. The results of the spectratype analysis demonstrated that the patients who received nonmyeloablative conditioning together with either bone marrow or peripheral blood stem cells exhibited more rapid reconstitution of T-cell repertoire complexity.

Abstract
Hematopoietic progenitor cell transplantation is often associated with severe mucosal toxicity. The need for parenteral analgesics and parenteral nutrition are evidence of the severity of the problem in individual patients. However, the increased risk for systemic infection related to bacteremia associated with the breakdown of mucosal barriers is a significant cause of morbidity and mortality as well. There is a multitude of grading scales, demonstrating the lack of consensus among clinicians in this area. Multiple agents have been used prophylactically and therapeutically to address mucositis. While efforts have been less successful in the past, the advent of newer agents including amifostine, keratinocyte growth factor, transforming growth factor beta and interleukin-11 provides hope that this toxicity will be significantly decreased in the near future.

Abstract
T cell depletion using the murine monoclonal antibody (moAb) T10B9 is unique in that the T cell receptor (TCR)gamma delta bearing subset is relatively spared compared to the TCR alpha beta + subset. We evaluated the probabilities of engraftment, acute and chronic graft-versus-host disease (GVHD), relapse, and survival in 273 recipients of marrow T cell depleted using T10B9. Sixty-two patients received marrow from an HLA-identical sibling, 54 patients received partially matched related donor marrow and 157 patients received unrelated donor marrow. Limiting dilution analysis (LDA) was used to estimate total clonable T cell dose in all patients and a modified LDA using moAb-coated immunomagnetic beads was used to estimate TCR alpha beta +, CD4+, and CD8+ T cells in a subset of patients. TCR gamma delta + cell dose was estimated by flow cytometry. Cox proportional hazards regression models were used to assess the impact of T cell subset dose/kg of body weight on outcome. We found a significant association of TCR gamma delta + T cell dose (P = 0.004), but not TCR alpha beta + T cell dose or total clonable T cell dose, with the probability of engraftment. TCR alpha beta +, CD4+, CD8+ and total clonable T cell dose were significantly associated (P < 0.001) with the risks of grade 2-4 acute GVHD in recipients of marrow from related donors but not in recipients of marrow from unrelated donors. Neither total clonable T cell dose nor any T cell subset dose was found to be significantly associated with chronic GVHD, relapse or survival. The results confirm preclinical studies showing TCR gamma delta + T cells promote engraftment. TCR gamma delta + T cells are not associated with an increased risk of acute GVHD while TCR alpha beta T cells are associated with acute GVHD but not engraftment in recipients of marrow grafts T cell depleted using T10B9. These findings support the hypothesis that T cell subsets differentially contribute to alloengraftment and GVHD.

Abstract
PURPOSE To compare outcomes of bone marrow transplants for leukemia from HLA-identical siblings, haploidentical HLA-mismatched relatives, and HLA-matched and mismatched unrelated donors. PATIENTS A total of 2,055 recipients of allogeneic bone marrow transplants for chronic myelogenous leukemia (CML), acute myelogenous leukemia (AML), and acute lymphoblastic leukemia (ALL) were entered onto the study. Transplants were performed between 1985 and 1991 and reported to the International Bone Marrow Transplant Registry (IBMTR). Donors were HLA-identical siblings (n = 1,224); haploidentical relatives mismatched for one (n = 238) or two (n = 102) HLA-A, -B, or -DR antigens; or unrelated persons who were HLA-matched (n = 383) or mismatched for one HLA-A, -B, or -DR antigen (n = 108). HLA typing was performed using serologic techniques. RESULTS Transplant-related mortality was significantly higher after alternative donor transplants than after HLA-identical sibling transplants. Among patients with early leukemia (CML in chronic phase or acute leukemia in first remission), 3-year transplant-related mortality (+/-SE) was 21% +/- 2% after HLA-identical sibling transplants and greater than 50% after all types of alternative donor transplants studied. Among patients with early leukemia, relative risks of treatment failure (inverse of leukemia-free survival), using HLA-identical sibling transplants as the reference group, were 2.43 (P < .0001) with 1-HLA-antigen-mismatched related donors, 3.79 (P < .0001) with 2-HLA-antigen-mismatched related donors, 2.11 (P < .0001) with HLA-matched unrelated donors, and 3.33 (P < .0001) with 1-HLA-antigen-mismatched unrelated donors. For patients with more advanced leukemia, differences in treatment failure were less striking: 1-HLA-antigen-mismatched relatives, 1.22 (P = not significant [NS]); 2-HLA-antigen-mismatched relatives, 1.81 (P < .0001); HLA-matched unrelated donors, 1.39 (P = .002); and 1-HLA-antigen-mismatched unrelated donors, 1.63 (P = .002). CONCLUSION Although transplants from alternative donors are effective in some patients with leukemia, treatment failure is higher than after HLA-identical sibling transplants. Outcome depends on leukemia state, donor-recipient relationship, and degree of HLA matching. In early leukemia, alternative donor transplants have a more than twofold increased risk of treatment failure compared with HLA-identical sibling transplants. This difference is less in advanced leukemia.

Abstract
Recipients of marrow from alternative donors (unrelated or HLA-mismatched related donors) have a higher incidence of post-transplant complications compared to recipients of marrow from HLA-identical siblings. HLA disparity undetected by routine typing techniques has been suggested as one cause for the increased complications observed. Limiting dilution analysis (LDA) of donor-derived, host-reactive T cell precursor frequency prior to transplant has been proposed as a surrogate indicator of underlying HLA disparity which might be used to predict transplant outcome and aid in donor selection. We compared results of LDA of host-reactive IL-2 producing helper T lymphocytes (HTLp) and/or cytolytic T lymphocytes (CTLp) in 77 alternative marrow donor/recipient pairs with transplant outcome using univariate and multivariate analysis. All donor grafts were depleted ex vivo of mature T cells. Median patient age was 15 years (1-53). Donor selection was based on serologic typing for HLA class I and high resolution oligotyping for HLA-DRB1-DRB5, and HLA-DQB1. HLA-A and HLA-B locus antigens were retrospectively defined by one dimensional isoelectric focusing (IEF). Cox proportional hazards regression models were used to assess the impact of frequency and estimated cell dose of CTLp and HTLp on outcome. The CTLp assay was most sensitive to HLA-A and HLA-B locus disparity detected by serology or IEF. The HTLp assay detected class I disparity but was most strongly reactive in the presence of HLA-DRB1 disparity. Univariate analysis indicated a significant association of CTLp frequency and dose with severe (grades 3-4) acute graft-versus-host disease (GVHD), and of CTLp dose with chronic GVHD. Both assays were associated with survival and neither assay was associated with relapse. After adjustment for other significant covariables including known HLA disparity, the association of CTLp with acute GVHD was lost, however, CTLp frequency and CTLp dose remained associated with survival and HTLp frequency was associated with chronic GVHD. These data support the hypothesis that post-BMT complications may be influenced not only by T cell dose but by the alloreactive potential of the cells infused. LDA of alloreactive potential was useful in detecting disparity and in predicting survival or chronic GVHD in recipients of alternative donor TCD marrow grafts.

Abstract
T cell depletion (TCD) has been achieved using techniques that cause the inactivation, lysis, or physical removal of T cells from the donor marrow. The clinical results of TCD reflect, in part, the degree of TCD achieved and the subsets that are removed. To better evaluate TCD using the monoclonal antibody (mAb) T10B9, we have performed a series of flow cytometry and mAb blocking studies and have developed a new limiting dilution assay (LDA) that allows the detection of T cell subsets that survive treatment. T cell growth was stimulated with PHA, rIL-2, and irradiated feeder PBMC in a total well volume of 20 microliters. Growth was scored by microscopic examination on days 14-16 of incubation. Immunomagnetic beads coated with mAb were added to the growing wells and incubated, then the plates were fixed to a template of samarium cobalt magnets before washing away nonadherent cells. Wells in which > 50 cells bound > or = 2 beads were scored as positive. Flow cytometry indicated that T10B9 recognized all T cells, but complement-mediated lysis spared a significant proportion of the TCR gamma delta + subset. The epitope recognized by T10B9 on TCR gamma delta + cells appears to be differentially expressed compared with TCR alpha beta + T cells based on antibody blocking studies. In contrast to antibodies to CD3 epsilon, T10B9 binds less well to TCR gamma delta + cells, possibly resulting in incomplete complement-mediated lysis of this subset. The relative sparing of TCR gamma delta + cells was found in marrow and peripheral blood. Subset LDA confirmed that the TCR gamma delta + cells detected by flow cytometry were capable of growth and further showed that OKT3 did not spare TCR gamma delta + cells. The subset LDA should prove useful in helping to assess the role of T cell subsets in clinical events post-TCD bone marrow transplantation.

Abstract
Alternative donor bone marrow transplantation (BMT) to treat severe aplastic anaemia (SAA) in children and young adults has been complicated by high rates of graft rejection and severe graft-versus-host disease (GVHD). We hypothesized that increased immunosuppression combined with T-cell depletion of the marrow graft would enable successful use of unrelated donor BMT in this disease. Preconditioning consisted of cytosine arabinoside, cyclophosphamide, and total body irradiation (TBI). T-cell depletion was with the anti-CD3 antibody T10B9. GVHD prophylaxis consisted of cyclosporine A. 28 previously transfused patients were transplanted. Nine donor/recipient pairs were HLA matched. As of 1 January 1996, 15/28 (54%) patients are alive, transfusion independent and well with a range of follow-up of 13 months to 8 years (median 2.75 years). Fatalities include all three patients with nonengraftment and all three patients with grade III/IV GVHD. Other fatalities were due to infections or therapy-related toxicity. The incidence >or= grade II acute GVHD was 28%. These data show that in children with SAA who have failed immunosuppression, unrelated donor BMT offers a reasonable hope of long-term survival.

Abstract
The effect of donor/recipient histocompatibility on relapse in patients receiving T-cell-depleted (TCD) grafts for chronic myelogenous leukemia (CML) was evaluated. Specifically, we sought to determine whether TCD results in an attenuation of the graft-versus-leukemia (GVL) effect on recipients of unrelated marrow grafts similar to that observed in HLA-identical sibling marrow transplantations. This question was addressed by comparative analysis of the relapse rates in marrow grafts who otherwise received identical preparative regimens and graft-versus-host disease (GVHD) prophylaxis schedules (T-cell depletion with T10B9 monoclonal antibody and complement plus posttransplant cyclosporine) and by serial molecular analyses using the polymerase chain reaction (PCR) to detect the bcr/abl RNA transcript in patients transplanted with unrelated donor grafts. Patients transplanted with advanced disease (accelerated phase or blast crisis) had equally high relapse rates, regardless of whether they received HLA-identical sibling (56%;95% confidence interval [CI], 29% to 82%) or unrelated marrow grafts (8%; 95% CI, 0% to 28%) had a significantly lower incidence of relapse than did patients transplanted with HLA-identical marrow grafts (47%; 95% CI, 23% to 71%; P = .002). Because all patients were similarly treated, these data indicate that the lower relapse rate in these unrelated patients was caused by an augmented GVL effect that was most likely attributable to increased HLA disparity between donor and recipient. The probability of developing both acute and chronic GVHD was significantly increased in chronic-phase recipients of unrelated marrow grafts, suggesting that the enhanced GVL effect was at least partly GVHD-associated. The lack of such a finding in advanced disease patient receiving unrelated marrow grafts raises the possibility that clinically significant GVL effect after TCD marrow transplantation was limited and confined to patients with more indolent disease. Serial PCR analyses for the presence of the bcr/abl RNA transcript showed that the vast majority of patients transplanted in chronic phase with unrelated marrow grafts were persistently PCR-negative, indicating that the GVL effect was durable in these patients. Most of these patients were observed to become PCR negative within 1 to 2 months after transplantation, showing that early eradication of leukemia was possible with TCD marrow grafts. This study shows that the use of unrelated marrow grafts compensates for reduced GVL reactivity associated with TCD in patients transplanted for CML. Furthermore, these data indicate that, in selected patient populations with CML, TCD can be used to reduce GVHD without a commensurate compromise in the GVL effect.

Abstract
A series of human CD8 transgenic (hCD8 Tg) mice with differential expression in the thymus and periphery were produced to investigate CD8 coreceptor regulation of repertoire selection and T cell responses. Expression of hCD8 markedly enhanced responses to both HLA class I molecules and hybrid A2/Kb molecules providing functional evidence for a second interaction site, outside of the alpha 3 domain, which is essential for optimal coreceptor function. Peripheral T cell expression of hCD8 was sufficient to augment responsiveness to HLA class I, as hCD8 Tg mice which lacked thymic expression responded as well as mice expressing hCD8 in the thymus and periphery. Both murine CD8+ and CD4+ T cells expressing hCD8 transgenes exhibited markedly enhanced responses to foreign HLA class I, revealing the ability of T cell receptor repertoires selected on either murine class I or class II to recognize human class I major histocompatibility complex (MHC). In contrast to recognition of foreign class I, thymic expression of hCD8 transgenes was absolutely required to enhance recognition of antigenic peptide restricted by self-HLA class I. Thus, our studies revealed disparate requirements for CD8 coreceptor expression in the thymus for selection of a T cell repertoire responsive to foreign MHC and to antigenic peptides bound to self-MHC, providing a novel demonstration of positive selection that is dependent on human CD8.

Abstract
Recognition of thrombotic thrombocytopenic purpura (TTP)/hemolytic uremic syndrome (HUS) following BMT has increased in recent years. The pathogenesis and etiology may be related to endothelial cell damage secondary to irradiation and/or CsA. Optimal management of this condition remains unclear. Due to similarity between this syndrome and classical TTP, patients with TTP/HUS following BMT are commonly treated with therapeutic plasma exchange (TPE). We describe our experience with 9 such patients who were treated with TPE (8 cases) and immunoadsorption with a Staphylococcal Protein A column (1 case). The exchanges were done with fresh frozen plasma and/or cryoprecipitate-depleted frozen plasma. Out of 8 patients treated with TPE, 6 died within 2 months of TPE due to secondary infections, metabolic disturbances and progression of TTP/HUS. Of these 6 patients, 5 had no hematological response, while 1 had hematological improvement. Two patients are alive 4 and 3 years later, however, they had shown only minimal hematological response at the end of 28 and 20 TPE, respectively. Their renal function remains stable but severely reduced. The ninth patient who received Staphylococcal Protein A column treatment died within 5 days of treatment without hematological improvement. Thus, in contrast to its effectiveness in classical TTP, TPE does not appear to be as effective in the management of well established TTP/HUS following BMT.

Abstract
Preliminary studies in allogeneic BMT suggest that recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) is well tolerated. This is a prospective, multicenter, randomized, double-blind, placebo-controlled trial. Yeast-derived rhGM-CSF 250 micrograms/m2/day or placebo was administered by 4-hour i.v. infusion starting on the day of marrow infusion (day 0) to day 20. All patients received HLA-identical sibling marrow and cyclosporine and prednisone for GVHD prophylaxis. Fifty three patients received rhGM-CSF and 56 received placebo. Comparison of demographics revealed no differences. The time to achieve an absolute neutrophil count of > 0.5 x 10(9) cells/l was shortened in rhGM-CSF treated patients (day 13 vs. 17, P = 0.0001). The incidences of grade III-IV mucositis and infection were significantly reduced (P = 0.005, P = 0.001, respectively) and duration of hospitalization was modestly shortened by 1 day (P = 0.02) in rhGM-CSF treated patients. No differences in platelet recovery, erythrocyte recovery, incidence of veno-occlusive disease, GVHD severity, relapse or survival were observed. In conclusion, rhGM-CSF is well tolerated and reduces post-transplant morbidity in patients undergoing HLA-identical allogeneic BMT.

Abstract
It has been suggested that cord blood T cells may be less able to mediate GVHD than marrow-derived T cells due to their naive status. A decreased potential for GVHD may be advantageous for allogeneic transplant, but this benefit might be counteracted by loss of the GVHD associated graft-versus-leukemia (GVL) effect. The GVL potential of cord blood could be doubly compromised since cord blood NK cell activity is also decreased. To assess these issues we have performed extensive comparative functional and immunophenotypic evaluations of cord and adult mononuclear cells. We found a somewhat reduced alloproliferative, allostimulatory and allocytolytic capacity of cord blood mononuclear cells in bulk assays but not by limiting dilution assays. Immunophenotyping revealed no significant differences in the proportion of major lymphocyte subsets with the exception of the previously recognized predominance of CD45RA+ cells in both CD4 and CD8 cord blood T cells. Cord blood T cells expressed normal percentages of the cellular adhesion molecules, CD11a, CD18 and LFA-3; however, the antigen density of each of these molecules was less than that found on adult T cells. Fewer resting cord blood T cells expressed CD54, the ligand for LFA-1. Cord blood B cells and monocytes expressed normal levels of HLA-class I and HLA class II DR, DP and DQ antigens, suggesting that the decreased expression of cellular adhesion molecules or their receptors rather than a decrease in expression of HLA might have contributed to the lower alloreactivity of cord blood. Although the percentages of NK cells and NK cell subsets in adult and cord blood were similar our data confirmed that cord blood has very low NK lytic activity. In contrast, LAK activity was much more readily induced in cord blood compared with adult PBMC, a finding which could be explained in part by a higher frequency of LAK precursors and a more rapid expansion of NK cells in response to culture with medium containing of NK cells in response to culture with medium containing IL-2. Cord blood LAK cells were readily able to lyse fresh leukemia targets from patients with ALL, AML and CML. The data indicate that although the alloreactive potential of cord blood cells may be somewhat decreased, it is not absent and must be considered a factor in cord blood transplants. LAKp with the potential to lyse leukemia are present in increased numbers in cord blood and might contribute to the GVL effect of a cord blood transplant.

Abstract
PURPOSE To assess the immunosuppressive capacity of hyperfractionated total lymphoid irradiation and cyclophosphamide for transplantation of unmodified allogeneic marrow in sensitized aplastic anemia patients. METHODS AND MATERIALS From February 1983 to September 1990, 23 multiply transfused aplastic anemia patients underwent unmodified bone marrow transplantation from HLA genotypically identical sibling donors following preparation with 6 Gy hyperfractionated total lymphoid irradiation and 160 mg/kg cyclophosphamide. Graft-versus-host disease prophylaxis included steroids in one patient, methotrexate in four, cyclosporine in seven, and methotrexate/cyclosporine in 12. There were 17 males and 6 females with a median age of 13 (range: 2.5-32). RESULTS One patient died early before engraftment of bacterial sepsis. Twenty-two patients were evaluable for engraftment. Three experienced graft failure including one primary, and two late graft failures associated with cyclosporine withdrawal. Acute graft-versus-host disease occurred in 7/22 (> or = grade II in 6), and chronic graft-versus-host disease in 3/17 patients. Except for a patient who received total body irradiation for a second transplant, no patient in this series developed interstitial pneumonia. Fifteen patients are alive with follow-up of 38-125 months (median 68). The overall actuarial survival at 5 years is 69%, at 8 years it is 60%, with one late death. The survival of adult patients was similar to that of younger patients (> or = 16 years old: 63%, < 16 years old: 55%). The development of acute graft-versus-host disease adversely influenced survival (88% with Grade 0-I, 17% with grade II-IV; p = 0.002). No hypothyroidism or secondary malignancies have been documented in this series. CONCLUSION Pretransplant immunosuppression with 6 Gy of hyperfractionated total lymphoid irradiation and 160 mg/kg CY reduces but does not eliminate the incidence of graft failure in sensitized aplastic anemia patients. The dose and the mode of administration of total lymphoid irradiation in this trial may be associated with a lower incidence of late side effects. Survival is comparable to that obtained using preparative regimens without radiation.

Abstract
The analysis of the T cell repertoires involved in local or systemic immune responses is beginning to play an important role in many clinical situations. These include autoimmunity, response to viral or bacterial superantigens, alloimmunity including allograft rejection, and tumor immunity. Here we analyze circulating T cell repertoires by determining TCR beta-chain gene complexity using a modification of V beta family-specific PCR. This approach, called CDR3 size spectratyping, uses the size heterogeneity of the CDR3 as a further source of specificity in TCR analysis. It has been used here to analyze the complexity and stability of circulating T cell repertoires in normal adults, including bone marrow donors, and bone marrow transplant recipients. Normal spectratypes are both complex and stable. The repertoire complexity of marrow recipients correlates with their state of immune function. Contractions and gaps in repertoires are revealed in individuals suffering from recurrent infections associated with T cell impairment. Spectratype analysis is applicable to other studies of specific repertoire skewing such as may be associated with immunodeficiency or found at sites of immune activity.

Abstract
The analysis of the T cell repertoires involved in local or systemic immune responses is beginning to play an important role in many clinical situations. These include autoimmunity, response to viral or bacterial superantigens, alloimmunity including allograft rejection, and tumor immunity. Here we analyze circulating T cell repertoires by determining TCR beta-chain gene complexity using a modification of V beta family-specific PCR. This approach, called CDR3 size spectratyping, uses the size heterogeneity of the CDR3 as a further source of specificity in TCR analysis. It has been used here to analyze the complexity and stability of circulating T cell repertoires in normal adults, including bone marrow donors, and bone marrow transplant recipients. Normal spectratypes are both complex and stable. The repertoire complexity of marrow recipients correlates with their state of immune function. Contractions and gaps in repertoires are revealed in individuals suffering from recurrent infections associated with T cell impairment. Spectratype analysis is applicable to other studies of specific repertoire skewing such as may be associated with immunodeficiency or found at sites of immune activity.

Abstract
Sixteen adults were studied for the first 100 days after allogeneic bone marrow transplant to assess the pathogenic role of human herpesvirus-6 (HHV-6) infection in patients with unexplained febrile illnesses. HHV-6 was directly isolated from the blood of 6 patients. Analysis of the clinical courses of these 16 patients revealed otherwise unexplained posttransplant marrow suppression in 5 patients. Idiopathic marrow suppression occurred more frequently in patients with concurrent HHV-6 viremia (4/6) than in those from whom HHV-6 was not isolated from peripheral blood (1/10, P < .05). An etiologic role for the virus was also supported by isolation of HHV-6 from the bone marrow of all 4 patients at the time of marrow suppression and by in vitro colony-forming unit (cfu) assays that demonstrated that HHV-6 could inhibit cfu-granulocyte-macrophage and burst-forming unit-erythroid growth from human bone marrow. By restriction enzyme mapping, all clinical isolates were type B, suggesting that bone marrow transplant recipients may be preferentially infected with and reactivate this HHV-6 subtype. This study implicates HHV-6 as a novel cause of bone marrow suppression in marrow transplant recipients.

Abstract
In order to understand the structural organization of the human CD8 beta locus, genomic clones containing CD8 beta sequences were isolated and analyzed. Physical linkage of these clones with the CD8 alpha locus using pulsed-field electrophoresis revealed a duplication of the CD8 beta locus. CD8B-1 lies 35 kb upstream from the CD8 alpha locus and contains eight exons, including four alternatively spliced cytoplasmic exons. The CD8B-2 gene contains six exons and is at present unlinked to CD8B-1. Analysis of sequences upstream to the leader exon of the CD8B-1 and CD8B-2 genes revealed a GC-rich promoter which lacks canonical "CCAAT" and "TATA" motifs, but which has sites for multiple transcriptional activators and three additional elements which are conserved in the murine CD8 beta promoter. Seven unique CD8 beta cDNA isoforms were isolated and characterized, which derive from alternative splicing of the transmembrane and/or cytoplasmic exons. Three cDNA are membrane spanning, while the remaining four isoforms lack a transmembrane region and are potentially secreted. These transcripts are differentially expressed in the thymus and in the periphery. Transfection experiments in murine fibroblasts confirmed that the membrane CD8 beta isoforms could be expressed as heterodimers with the CD8 alpha chain. The regulated expression of multiple CD8 beta cytoplasmic isoforms and their potential role in T lymphocyte signal transduction is discussed.

Abstract
Some in vitro-generated allospecific T-cell clones can kill target cells bearing specific antigen, whereas others can only proliferate in response to that antigen. The mechanism of target lysis by clones that exhibit antigen-specific cytotoxicity is thought to involve the exocytosis of lytic granules, which contain the pore-forming protein perforin. Here, CD4+, CD8+, and CD4-8- T-cell clones, positive for CD3 and the alpha/beta T-cell receptor, were tested for their ability to lyse the mouse-anti-human CD3 hybridoma OKT3; this hybridoma has been shown to trigger the cytolytic mechanism in cytotoxic T cells regardless of their clonal specificity. We found that all in vitro-generated allospecific T-cell clones can efficiently lyse the OKT3 targets whether or not they can kill alloantigen-bearing lymphoblastoid B-cell line targets. Furthermore, all tested clones contained perforin. The OKT3 hybridoma was not lysed by perforin-negative, CD3+ leukemic T-cell lines or by CD3- NK clones. Thus, the presence of perforin in T-cell clones correlated with their ability to lyse OKT3 targets, but not with their ability to lyse alloantigen-bearing targets. These results demonstrate that T-cell clones that are nonlytic when activated by specific antigen nevertheless contain a complete lytic mechanism and also support the proposed central role in perforin in that mechanism.

Abstract
In this study, we have evaluated 14 large granular lymphocyte (LGL) expansions, 11 of which were CD8+. Analysis of the membrane expression of the alpha and beta chains of the CD8 antigen, using specific monoclonal antibodies (MoAbs), has shown that LGL expansions with the CD3+, CD4+, CD8+, CD57+ T-cell receptor (TcR) alpha beta phenotype bear the CD8 alpha/alpha isoform, while the CD3+, CD4-, CD8+, CD57+ TcR alpha beta samples were positive for both the CD8 alpha and CD8 beta chains. These data were confirmed also by messenger RNA analysis. One additional case, with a peculiar phenotype (CD3-, CD2-, CD4-, CD8+, CD57-) and a germline configuration of the TcR beta and gamma chain genes, expressed only the CD8 alpha chain. After additional phenotypic analysis with a wider panel of MoAbs, it was found that the beta chain of the interleukin-2 receptor was constitutively expressed on the majority of the samples tested, and that most of the monoclonal samples coexpressed CD45RA/R0 antigens. Using MoAbs directed against the variable regions of the TcR beta chain, we could show a preferential V beta region restriction in the CD8+ monoclonal cases. This more extensive characterization of CD8+ LGL expansions has further documented the marked heterogeneity within this rare condition and allowed a better phenotypic dissection between the monoclonal and polyclonal cases.

Abstract
PURPOSE To increase the hematologic tolerance of interferon-alpha (IFN alpha) and zidovudine combination therapy by the addition of granulocyte-macrophage colony-stimulating factor (GM-CSF), and to evaluate the safety, tolerance, and potential efficacy of the combination in patients with Kaposi's sarcoma and AIDS. PATIENTS AND METHODS Seventeen patients with Kaposi's sarcoma associated with AIDS received zidovudine 200 mg orally every 4 hours and GM-CSF 5 micrograms/kg/d subcutaneously. Successive cohorts received IFN-alpha 2b at a daily subcutaneous dose of 5, 10, or 20 million units. The dose of GM-CSF was titrated to maintain the neutrophil count between 1 and 5 x 10(9) cells/L. Doses of all three drugs were reduced, as required, for nonhematologic toxicities. RESULTS GM-CSF induced leukocytosis in all patients. On average, a dose of 1.25 micrograms/kg/d was sufficient to maintain the neutrophil count within the desired range. The combination of 20 million units of IFN-alpha with zidovudine and GM-CSF induced dose-limiting toxicity in four of six patients. The major side effects were constitutional symptoms, which included malaise, anorexia, fatigue, fever, and were dose-limiting in three patients. Severe anemia and/or thrombocytopenia developed in three patients. Seven patients (41%; 95% confidence interval [CI], 18% to 64%) showed objective tumor regression that persisted for a median of 51 weeks. A rapid decrease in free-serum p24 antigen levels was observed in seven patients who had measurable levels at baseline; the mean time required to isolate human immunodeficiency virus (HIV-1) from peripheral-blood cells was increased by 7 days. The number and percentage of CD4-positive lymphocytes showed no significant change. CONCLUSIONS GM-CSF prevents neutropenia induced by the IFN-alpha and zidovudine combination and induced no adverse effects on immune function or HIV activity. However, nonhematologic toxicity precluded a major increase in the maximum-tolerated doses of IFN-alpha and zidovudine.

Abstract
We prospectively evaluated the efficacy of T-cell-depleted bone marrow transplantation (BMT) in adults with de novo acute nonlymphocytic leukemia (ANLL) in first complete remission (CR), with regard to relapse-free survival and incidence of graft-versus-host disease (GvHD). Thirty-one patients older than 16 years (range, 16.5 to 43.2) received T-cell-depleted grafts for this purpose from related HLA/MLC-compatible donors. Twelve of the patients were older than 30 years at the time of transplantation. Patients were prepared with hyperfractionated total body irradiation (HFTBI; 1,375 to 1,500 cGy) and high-dose cyclophosphamide (120 mg/kg). T cells were removed from the marrow grafts by a two-step soybean lectin agglutination and sheep red blood cell (sRBC)-rosette procedure, achieving a 2.5- to 3-log depletion of clonable T lymphocytes. No additional prophylaxis against GvHD was administered. The median age at transplantation was 28.8 years; the median interval from diagnosis to transplantation was 3.8 months, and from CR was 2.7 months. Seventy-four percent received consolidation after remission induction therapy. The product-limit estimate of disease-free survival (DFS) at 3 years is 45% (95% confidence interval [CI], 24% to 66%), and the cause-specific probability of relapse is 13%. The median follow-up of the survivors is 72 months (range, 34.5 to 95.6). Median time to achieve a sustained absolute neutrophil count of 500 or greater was 16 days, and to maintain an untransfused platelet count of 20,000 or greater was 20 days. Five patients suffered immune-mediated graft rejection. Three patients developed grade I to II acute GvHD limited to the skin, which resolved promptly with brief courses of systemic steroids. None of the patients has developed clinically apparent chronic GvHD or a secondary lymphoproliferative disorder, and no patient is receiving immunosuppressive therapy. T-cell-depleted BMT by the method reported here is a favorable option as postremission therapy for adults with de novo ANLL in first remission who have an HLA/MLC-compatible related donor, and it is not associated with an increased risk of relapse posttransplant.

Abstract
The CD8 glycoprotein is a lymphocyte differentiation antigen comprised of two distinct polypeptide chains, alpha and beta, which have the capacity to form homodimeric (CD8 alpha/alpha) or heterodimeric (CD8 alpha/beta) cell surface complexes. The majority of monoclonal antibodies which recognize the human CD8 antigen react with the CD8 alpha chain, while a single mAb, referred to as T8/2T8-5H7 (or 2ST8-5H7), has been identified which binds to the CD8 alpha/beta heterodimer. In order to generate antibodies specific for CD8 beta, murine fibroblast transfectants were constructed which express the human CD8 beta chain in combination with either the human CD8 alpha chain or the murine CD8 alpha homologue, the Lyt-2 molecule. These transfectants were used to raise polyclonal heteroantisera in mice. Transfectants expressing human CD8 alpha/beta heterodimers induced moderate anti-CD8 alpha titers, but were weakly effective in generating anti-CD8 beta titers, despite high level cell surface expression of this protein. In contrast, transfectants expressing mixed-species CD8 heterodimers (murine CD8 alpha and human CD8 beta) induced high anti-CD8 beta titers in immunized mice. Following fusion of splenocytes from mice immunized with mixed-species CD8 transfectants, the mAb 5F2 was isolated which specifically recognizes the human CD8 beta chain. Unlike T8/2T8-5H7, the mAb 5F2 can bind the CD8 beta chain irrespective of its pairing partner, and can immunoprecipitate the CD8 beta protein from cells transfected with the CD8 beta gene in the absence of the human or mouse CD8 alpha gene product. Anti-CD8 beta antibodies should help elucidate the extent of biochemical heterogeneity of the CD8 beta protein, and will also be useful in defining the role of the CD8 beta protein in thymocyte and lymphocyte development, recognition and activation.

Abstract
We investigated whether elevated serum levels of beta 2-microglobulin and neopterin were related to the abnormal in vivo production of interferon described in patients with human immunodeficiency virus (HIV) infection, and whether these factors might add to measurements of CD4+ T cells in predicting survival and tumor regression in patients with Kaposi sarcoma associated with AIDS. beta 2-Microglobulin and neopterin levels were strongly correlated (r = 0.82), and were each significantly higher in patients with detectable serum interferon-alpha activity. Inverse correlations were observed between prognosis and levels of these serum products. Prediction by CD4+ T-cell count of tumor regression after treatment with interferon-alpha and zidovudine was improved by each of two factors: (a) the presence or absence of endogenous interferon-alpha activity, and (b) a combined variable reflecting relative levels of the interferon-inducible products, beta 2-microglobulin and neopterin. The level of beta 2-microglobulin was the single best predictor of survival. When beta 2-microglobulin was not considered, the endogenous interferon-alpha variable was the best predictor of survival, and the prediction was enhanced by addition of the combined variable, or the neopterin value alone. We conclude that serologic markers, which directly or indirectly reflect activation of the endogenous interferon system, may be valuable adjuncts to CD4+ T-cell counts in assessing prognosis and selecting and evaluating treatments for patients with Kaposi sarcoma and AIDS.

Abstract
The circulating lymphocytes of 88 consecutive patients following autologous, conventional, or T-cell depleted bone marrow transplantation were serially analyzed for B-cell surface antigen expression and function. In the majority of patients, except for those who developed chronic graft-versus-host disease, the number of circulating CD20+ B cell normalized by the fourth posttransplant month. The earliest detectable B cells normally expressed HLA-DR, CD19, surface immunoglobulin (slg), CD21, Leu-8, and lacked expression of CD10 (CALLA). In addition, the circulating B cells expressed CD1c, CD38, CD5, and CD23 for the first year following transplant, antigens that are normally expressed on a small percentage of circulating B cells in normal adults, but highly expressed on cord blood B cells. Similar to cord blood B cells, patient B cells isolated during the first year following transplant, proliferated normally to Staphylococcus aureus Cowan strain I (SAC), and produced IgM, but minimal or no IgG when stimulated with pokeweed mitogen and SAC, unlike normal adult B cells that produce both. The similar phenotype and function of posttransplant and cord blood B cells, and their similar rate of decline in patients and normal children adds further evidence to support the hypothesis that B-cell differentiation posttransplant is recapitulating normal B-cell ontogeny.

Abstract
Patients who have become split lymphoid chimeras (T cells of donor origin, B cells and monocytes of host origin) following transplantation of HLA-haploidentical marrow for the treatment of severe combined immunodeficiency disease provide a unique model for the study of tolerance. One such patient, UPN 345, was transplanted with maternal marrow and was found to have antidonor proliferative reactivity without detectable donor-directed cytotoxicity when tested at 18, 23, and 66 mos following bone marrow transplantation. In bulk culture, the proliferation to donor cells could be blocked by monoclonal antibodies to HLA-DR and -DQ. Nine clones with antidonor reactivity were established by limiting dilution techniques from a mixed lymphocyte culture between engrafted T cells and irradiated donor E rosette-negative cells. All of the clones were of maternal donor origin, and all were CD3+CD4+CD8-. The clones were tested for proliferative and cytotoxic activity toward donor, host, and paternal B-lymphoblastoid cell lines (B-LCL). Six clones proliferated strongly to maternal B-LCL but not to host B-LCL. Six clones were found to exclusively lyse maternal B-LCL. Four of the clones had both antidonor cytotoxic and antidonor proliferative reactivity. Monoclonal antibody blocking studies were performed on five of the six clones with cytotoxic activity. The antidonor cytotoxicity was not inhibited by monoclonal antibodies to class I determinants; however, three clones were inhibited in the presence of monoclonal antibody to DR, one clone was inhibited by anti-DQ monoclonal antibody, and one clone was inhibited by anti-DP monoclonal antibody. The cytotoxicity of all five clones was inhibited by monoclonal antibody to CD4. These data indicate that antidonor reactivity may also include a cytotoxic component which is not apparent in bulk cultures and which, based on our limiting dilution studies, is probably controlled by regulatory cells. Both the antidonor cytotoxicity and the antidonor proliferation appear to be directed primarily toward donor HLA class II antigens that are not shared with the patient.

Abstract
Thymulin, a peptide secreted by human thymic epithelial cells, circulates in peripheral blood. Levels of plasma thymulin (FTS-Zn) activity were analyzed in 21 patients with lethal combined immunodeficiency disorders who were treated with transplantation of HLA-haplotype-mismatched parental bone marrow depleted of T cells by differential agglutination with soybean agglutinin and E-rosetting (SBA-E-BMT). Among these 21 infants, 15 were patients with severe combined immunodeficiency (SCID) and 6 had combined immunodeficiency (CID) with Omenn's syndrome or CID with T cell predominance (CIDTP). In contrast to normal infants who possess high levels of plasma thymulin activity, 20 of the 21 patients demonstrated undetectable or low plasma thymulin levels for their age at admission prior to transplantation. Following SBA-E-BMT, however, thymulin became detectable in the plasma of 17 of 18 evaluable patients and reached normal or near-normal levels between 21 and 125 days posttransplant. In patients in whom the timing of engraftment could be established by emergence of donor lymphocytes, thymulin appeared in the plasma at approximately the same time as lymphoid chimerism was detected, and in all patients who were engrafted and immunologically reconstituted, the increment in thymulin levels preceded development of immune functions. These studies support the concept that normal marrow-derived cells in the graft can provide a stimulus necessary for induction of thymic epithelial secretory function in patients with thymic dysplasia. Further, immunologic reconstitution in these patients was not seen following SBA-E-BMT unless and until recovery of thymus function had been observed.

Abstract
OBJECTIVE To evaluate safety, tolerance, and potential efficacy of interferon-alpha and zidovudine combination therapy in patients with Kaposi sarcoma and the acquired immunodeficiency syndrome (AIDS). DESIGN Open, phase-I study with randomization between two preparations of interferon-alpha. SETTING Outpatient clinic of a cancer research center. PATIENTS Forty-three patients with Kaposi sarcoma associated with AIDS. INTERVENTIONS Patients were treated with interferon-alpha, 4.5, 9, or 18 million U/d, and zidovudine, 100 or 200 mg orally every 4 hours. MEASUREMENTS AND MAIN RESULTS Neutropenia was the major dose-limiting toxicity. Fatigue, liver enzyme elevation, anemia, and thrombocytopenia were dose-limiting in some patients. Maximum tolerated dosages for interferon-alpha 2a with zidovudine, respectively, were 4.5 million U/d with 200 mg every 4 hours or 18 million U/d with 100 mg every 4 hours. An interferon-alpha n1 [corrected] dosage of 9 million U/d with zidovudine dosages of either 100 or 200 mg every 4 hours induced dose-limiting toxicity in most patients. Of 37 evaluable patients, 17 (46%; 95% CI, 30% to 62%) showed complete or partial tumor regression. Antitumor effects occurred more frequently in patients with baseline CD4 counts above 200 x 10(6) cells/L (65%) than in patients with lower baseline counts (30%, P = 0.05). Effects on CD4 cells were related to both initial CD4 count and interferon dose. Increased skin test reactivity and decreased serum human immunodeficiency virus (HIV) p24 antigen and virus recovery from blood cells were seen. CONCLUSIONS Combined therapy with interferon-alpha and zidovudine can be safely administered to patients with AIDS and Kaposi sarcoma. The observed effects on tumor growth, HIV replication, and immune function support further studies of the combination in patients at various stages of HIV infection.
