Graft Versus Host

Graft-versus-host disease (GVHD) remains a major clinical drawback of allogeneic hematopoietic stem cell transplantation (HSCT). Here, we investigated how the stress responsive heme catabolizing enzyme heme oxygenase-1 (HO-1, encoded by HMOX1) regulates GVHD in response to allogeneic hematopoietic stem cell transplantation in mice and humans. We found that deletion of the Hmox1 allele, specifically in the myeloid compartment of mouse donor bone marrow, promotes the development of aggressive GVHD after allogeneic transplantation. The mechanism driving GVHD in mice transplanted with allogeneic bone marrow lacking HO-1 expression in the myeloid compartment involves enhanced T cell alloreactivity. The clinical relevance of these observations was validated in two independent cohorts of HSCT patients. Individuals transplanted with hematopoietic stem cells from donors carrying a long homozygous (GT)n repeat polymorphism (L/L) in the HMOX1 promoter, which is associated with lower HO-1 expression, were at higher risk of developing severe acute GVHD as compared to donors carrying a short (GT)n repeat (S/L or S/S) polymorphism associated with higher HO-1 expression. In this study, we showed the unique importance of donor-derived myeloid HO-1 in the prevention of lethal experimental GVHD and we corroborated this observation by demonstrating the association between human HMOX1 (GT)n microsatellite polymorphisms and the incidence of severe acute GVHD in two independent HSCT patient cohorts. Donor-derived myeloid HO-1 constitutes a potential therapeutic target for HSCT patients and large-scale prospective studies in HSCT patients are necessary to validate the HO-1 L/L genotype as an independent risk factor for developing severe acute GVHD.

Abstract Beyond disease biology, the success of allogeneic hematopoietic stem cell transplantation (HSCT) in patients with hematological malignancies is mainly determined by the occurrence and extent of graft versus host disease (GVHD). Therefore, prevention of GVHD is the major goal and challenge in clinical HSCT. A calcineurin-inhibitor combined with methotrexate is the standard graft versus host disease (GVHD) prophylaxis after allogeneic hematopoietic stem cell transplantation (HSCT). Everolimus is a derivative of sirolimus, which also seems to mediate anti-leukemia effects. Given the potential synergism and favourable toxicity profile of everolimus and tacrolimus (EVTAC) after allogeneic HSCT we sought to investigate the efficacy of this combination in patients with either myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML). We report a combination of everolimus (days 0–56) and Tacrolimus (from day −1 on) in 24 patients (pts, median age 62 years) with either MDS (n=17) or AML (n=7) undergoing intensive busulfan-based conditioning followed by HSCT from related (n=4) or unrelated matched (n=12) or 1-allele mismatched (n=8) donors. All pts engrafted and only one experienced grade IV mucositis. However, although everolimus was scheduled to be administered up to day 56, patients received the drug a median of 44 days (range 10–56) only. The reason for premature discontinuation (50%) were either occurrence of early-onset (day 6) GVHD associated hyperbilirubinemia CTC grade 4 (n=1), transplantation-associated microangiopathy (TMA, n=3), sinusoidal obstructive syndrome (SOS) of the liver (n=6) or a drop of platelets after engraftment by at least 50% (n=2). Nine pts (37%) developed grade II–IV acute GVHD, however, chronic extensive GVHD was observed in 11 of 17 (64%) evaluable pts. TMA occurred in 7 pts (29%) with two cases of acute renal failure. In five out of seven patients with TMA either tacrolimus (n=4) or everolimus (n=1) blood through levels were slightly above the upper target level at the time of TMA appearance. The study was terminated prematurely because additional 6 pts (25%) developed SOS, which was fatal in two cases. With a median follow-up of 26 months, the 2-year overall survival rate is 47%. In conclusion, although this new combination appears to be effective as prophylactic regimen for acute GVHD, the incidence of TMA and SOS seems to be higher compared to other regimens. As a result this combination cannot be recommended as prophylactic regimen after busulfan-based intensive conditioning. However, studies in the context of TBI-based or reduced-intensity conditioning regimens might come to a different conclusion.

Routine methods to maximize the graft-versus-leukemia (GvL) activity of allogeneic hematopoietic stem cell transplantation (HSCT) without the detrimental effects of graft-versus-host disease (GvHD) are lacking. Depletion or inhibition of alloreactive T cells is partially effective in preventing GvHD, but usually leads to decreased GvL activity. The current model for the pathophysiology of acute GvHD describes a series of immune pathways that lead to activation of donor T cells and inflammatory cytokines responsible for tissue damage in acute GvHD. This model does not account for how allotransplant can lead to GvL effects without GvHD, or how the initial activation of donor immune cells may lead to counter-regulatory effects that limit GvHD. In this review, we will summarize new findings that support a more complex model for the initiation of GvHD and GvL activities in allogeneic HSCT, and discuss the potential of novel strategies to enhance GvL activity of the transplant.

Abstract Fetomaternal microchimerism suggests immunological tolerance between mother and fetus. Thus, we performed primary hematopoietic stem cell transplantation from a mismatched mother to thalassemic patient without an human leukocyte antigen–identical donor. Twenty-two patients with thalassemia major were conditioned with 60 mg/kg hydroxyurea and 3 mg/kg azathioprine from day −59 to −11; 30 mg/m2 fludarabine from day −17 to −11; 14 mg/kg busulfan starting on day −10; and 200 mg/kg cyclophosphamide, 10 mg/kg thiotepa, and 12.5 mg/kg antithymocyte globulin daily from day −5 to −2. Fourteen patients received CD34+-mobilized peripheral blood and bone marrow progenitor cells; 8 patients received marrow graft–selected peripheral blood stem cells CD34+ and bone marrow CD3/CD19-depleted cells. T-cell dose was adjusted to 2 × 105/kg by fresh marrow cell addback at the time of transplantation. Both groups received cyclosporine for graft-versus-host disease prophylaxis for 2 months after transplantation. Two patients died (cerebral Epstein-Barr virus lymphoma or cytomegalovirus pneumonia), 6 patients reject their grafts, and 14 showed full chimerism with functioning grafts at a median follow-up of 40 months. None of the 14 patients who showed full chimerism developed acute or chronic graft-versus-host disease. These results suggest that maternal haploidentical hematopoietic stem cell transplantation is feasible in patients with thalassemia who lack a matched related donor.

Abstract Background Chronic graft-versus-host disease (cGVHD) is the common long-term complication and the leading cause of non-relapse mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT), which has a significant impact on patient quality of life. Currently, mesenchymal stromal cells (MSCs) have been considered as a promising therapy for treating refractory acute/chronic GVHD and engraftment failure (EF) or poor graft function (PGF), but the efficacy of MSCs in the prophylaxis of cGVHD is rarely reported. Methods Eighty-two patients who received MSCs treatment after allo-HSCT were enrolled in our study, including 45 patients with refractory aGVHD, 33 patients with EF or PGF and 4 patients with virus infection. In order to evaluate the influence of bone marrow (BM) derived MSCs for the incidence and severity of cGVHD, 308 consecutive patients who underwent allo-HSCT in the same period but without MSCs treatment were considered as the control group. And no statistical significance was found between the two groups for the demographic and transplant characteristics. MSCs were given at a median dose of 1×106 cells/kg once weekly. Results All eighty-two patients in MSC group received a median of 5 (range:3-12) doses of MSCs per patient. In MSC group, seventeen patients (20.7%) had cGVHD, including 14 patients with limited cGVHD and 3 patients with extensive cGVHD. In the control group, 140 patients (45.5%) had cGVHD, including 95 patients with limited and 45 extensive cGVHD. The 2-year cumulative incidence of cGVHD was 26.7% (95%CI: 16.1%-37.5%) in MSC group and 50.4% (95%CI: 37%-63.8%) in the control group (P=0.037). Furthermore, the extensive cGVHD (3/82) in the MSC group were also significantly lower than those (45/308) in the control group (P=0.021). In addition, at a median follow-up time of 189 (range: 112-1035) days post-transplantation, 4 patients relapsed in MSC group and 13 patients relapsed in the control group. The incidence of tumor relapse was not different between the two groups (P=0.629). No short-term toxic side effects were observed and other secondary tumor occurred after MSCs treatment. Conclusion MSCs derived from BM reduce the incidence and severity of cGVHD after allo-HSCT, but not increase the risk of tumour relapse. Disclosures No relevant conflicts of interest to declare.

AbstractIt is unknown whether the severity, timing, and quality of graft-versus-host disease (GVHD) may be different after nonmyeloablative as compared with myeloablative hematopoietic stem cell transplantation (HSCT). Therefore, GVHD incidence, morbidity of skin, liver, and gut, requirements for immunosuppressive therapy, and survival were retrospectively analyzed in 44 patients who underwent nonablative HSCT and 52 who underwent ablative HSCT (median ages, 56 and 54 years, respectively). The nonablative transplantation regimen consisted of low-dose total body irradiation (TBI), preceded in some patients by fludarabine administration and followed in all patients by immunosuppression with mycophenolate mofetil (MMF) and cyclosporine (CSP). Those who underwent myeloablative HSCT were prepared with different TBI- and non-TBI–containing regimens and received CSP plus methotrexate or MMF for GVHD prophylaxis. The cumulative incidence of grades II-IV acute GVHD was lower after nonablative transplantation (64% vs 85%; P = .001), but there were no differences in the cumulative incidence of chronic GVHD requiring treatment (73% vs 71%; P = .96). Nonablative transplantation was associated with the delayed initiation of steroid treatment for GVHD (0.95 months vs 3.0 months; P < .001) and with the use of fewer systemic immunosuppressants in the first 3 months after transplantation (P ≤ .04). This corresponded to more prevalent skin and more severe gut morbidity 6 to 12 months after nonablative transplantation. Our results show that nonablative HSCT is associated with a syndrome of acute GVHD occurring after day 100 in many patients. This “late-onset acute GVHD” should be taken into consideration in the design of prospective studies comparing GVHD resulting from the two types of transplantation procedures.

Background. Acute graft-versus-host disease (aGVHD) involving skin is one of the most frequent complications of allogeneic hematopoietic stem cell transplantation (alloHSCT), usually diagnosed based on clinical manifestations. So far, skin biopsy with histopathological evaluation is the only method to confirm the diagnosis. Objective. In this prospective study we monitored alloHSCT recipients by dermoscopy in order to assess its utility as an alternative noninvasive tool to early diagnose acute GVHD. Methods. Thirteen consecutive patients who received alloHSCT were examined clinically and dermoscopically towards aGVHD [days 28 (±7), 56 (±7), and 100 (±7)], as well as in each patient who developed cutaneous aGVHD diagnosed according to clinical criteria (Glucksberg scale). Results. Six patients (46%) developed symptoms of cutaneous acute GVHD (grade 1, n=3; grade 2, n=3). Dermoscopic evaluation revealed pinkish or reddish background and well-visible, multiple thin telangiectasias. Conclusion. To our knowledge, this is the first report on the use of dermoscopy to evaluate skin involvement in the course of acute GVHD suggesting its role as a diagnostic tool in follow-up of GVHD, which can be also used before clinical symptoms occur.

Background. Graft-versus-host disease (GVHD) is a serious complication after allogeneic hematopoietic stem cell transplantation (HSCT). We designed a functional assay for assessment of individual risk for acute GVHD.Study Design and Methods. Blood samples were collected from patients and donors before HSCT. Two groups of seven patients each were selected, one in which individuals developed acute GVHD grades II–IV and one in which none showed any clinical signs of GVHD. Peripheral blood mononuclear cells (PBMCs) isolated from donors were incubated in mixed lymphocyte cultures (MLCs) with recipient PBMCs. The cells were characterized by flow cytometry before and after MLC.Results. Samples from donors in the GVHD group contained significantly lower frequencies of naïveγδT-cells and T-cells expressing NK-cell markers CD56 and CD94. Donor samples in this group also exhibited lower frequencies of naïve CD95+T-cells compared to controls. After MLC, there were dissimilarities in the CD4/CD8 T-cell ratio and frequency of CD69+T-cells between the two patient groups, with the non-GVHD group showing higher frequencies of CD8+and CD69+T-cells.Conclusion. We conclude that a thorough flow cytometric analysis of donor cells for phenotype and allogeneic reactivity may be of value when assessing pretransplant risk for severe acute GVHD.

Abstract Disrupted hematopoiesis and delayed immune reconstitution are life-threatening complications of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Although graft-versus-host disease (GVHD) is a major risk factor for the bone marrow (BM) insufficiency, how GVHD impairs BM hematopoiesis has been largely unknown. We hypothesized that BM stromal niche could be a target of GVHD. In major histocompatibility complex (MHC)–mismatched murine models of GVHD, we have demonstrated the early destruction of osteoblasts that especially affected B-cell lineages. The defective B lymphopoiesis was due to the impaired ability of BM stroma and osteoblasts to support the hematopoiesis, as evidenced by the failure of GVHD-affected BM to reconstitute the hematopoietic cells. The administration of anti-CD4 monoclonal antibody (mAb) ameliorated these effects and improved B lymphopoiesis while preserving graft-versus-tumor effects. Genetic ablation of Fas–Fas ligand signaling also partially restored B lymphopoiesis. Our present study provided evidence of BM GVHD, with the identification of osteoblasts as the main target for GVHD in BM. Moreover, our data showed the potential for mAb therapies to enhance immune reconstitution in vivo for patients undergoing allo-HSCT.
