Gradual Disappearance

The gradual disappearance of host antidonor isohemagglutinins after major ABO-mismatched hematopoietic stem cell (HSC) allografts has been attributed to the gradual destruction of host plasma cells by graft-versus-host effects. To corroborate this hypothesis, we retrospectively analyzed results from 383 major or major/minor ABO-mismatched unrelated and related HSC allografts performed between 1983 and 1998. All patients were conditioned by high-dose pretransplant therapy and given methotrexate/cyclosporine for graft-versus-host disease (GvHD) prophylaxis. Of the 383 patients, 155 had HLA-matched related and 228 had unrelated grafts. We asked whether unrelated recipients experienced a more rapid disappearance of isohemagglutinins than related recipients, and whether, within the groups of related and unrelated recipients, the titer disappeared faster in patients with GvHD than in those without GvHD. The median time to reach undetectable antidonor IgG and IgM titers was significantly shorter in unrelated recipients (46 versus 61 days; P = .016). In addition, related recipients with GvHD had a 2.2-fold increased likelihood (1.12-4.39,95% CI; P = .02) of reaching undetectable titers within 100 days than patients without GvHD. The persistence of antidonor isohemagglutinins led to significantly increased red blood cell (RBC) transfusion requirements in the ABO-mismatched related patients compared with ABO-matched counterparts. However, time to neutrophil and platelet engraftment, incidence of GvHD, and survival were not influenced by ABO incompatibility. In conclusion, our results corroborate the hypothesis that the rate of disappearance of antidonor isohemagglutinins after ABO-mismatched allogeneic HSC grafts is influenced by the degree of genetic disparity between donor and recipient, suggesting a graft-versus-plasma cell effect.

Abstract The increasing clinical indications for hematopoietic stem cell transplantation (HSCT) and improved clinical care throughout and following HSCT have led to not only long-term survival but also to an increasing incidence and prevalence of graft-versus-host disease (GVHD). Chronic GVHD (cGVHD) affects almost 50% of adult patients post-HSCT, with increasing incidence in pediatric patients as well. Oral cGVHD specifically has a reported prevalence ranging from 45% to 83% in patients who develop cGVHD and is more extensive in adult patients than in children. Oral cGVHD affects patients through clinically significant oral symptoms that may lead to significantly decreased caloric intake, oral infections, and increased health service utilization, and may thus affect overall health and survival. The most commonly used therapy for mucosal involvement of oral cGVHD is topical high-dose and ultra-high potency corticosteroids, and calcineurin inhibitors. This review of oral complications of cGVHD presents the clinical significance of oral cGVHD to HSCT survivors, our current understanding of the pathobiology of oral cGVHD and gaps in this evidence, and the global targeted interdisciplinary clinical research efforts, including the National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-versus-Host Disease. Current challenges regarding the management of oral cGVHD and strategies to advance our scientific understanding of this clinically significant chronic oral disease are presented.

OBJECTIVES/SPECIFIC AIMS: Allogeneic hematopoietic stem cell transplantation (allo-HCT) is a curative procedure for hematological malignancies. Chronic graft Versus host disease (cGVHD) is a lethal complication that often develops after allo-HCT. Fli-1 is an aberrantly expressed protein in cancers including erythroleukemia and melanoma, while being implicated in pathogenesis of systemic lupus in mice and humans, a disease with marked similarity to cGVHD. METHODS/STUDY POPULATION: cGVHD was induced using hematopoietic cells from conditional knock-out mice deficient for the fli-1 gene specifically on T cells and progression of cGVHD in murine allo-HCT recipients was monitored using a clinical scoring system, and changes in activation status of hematopoietic cell populations were quantified using flow cytometry. RESULTS/ANTICIPATED RESULTS: Recipients transplanted with fli-1 deficient T cells exhibited reduced cGVHD clinical scores compared with littermate wild-type controls. Donor-grafts containing fli-1 deficient T cells were associated with restrained T-cell responses including reduced Interferon-y cytokine production, PD-1 expression, and differentiation into follicular helper T cells. fli-1 T-cell deficient donor-grafts also improved donor B-cell reconstitution and reduced plasma cells in allo-HCT recipients relative to littermate wild-type control donor-graft recipients. DISCUSSION/SIGNIFICANCE OF IMPACT: Thus, inhibiting Fli-1 represents a promising therapeutic strategy for the goal of preventing cGVHD after allo-HCT while also directly targeting cancers which aberrantly express Fli-1.

Donor Variability

Graft versus host disease (GvHD) is a life-threating complication of allogeneic hematopoietic stem cell transplantation, which is initially treated with high dose corticosteroids. Approximately 50% of acute GvHD cases are resistant to steroid treatment, and two-year mortality rates in those steroid-resistant patients exceed 80%. Chronic GvHD necessitates prolonged corticosteroid use, which is typically associated with limited efficacy and troublesome adverse effects. No agent has yet been established as an optimal second line therapy for either acute or chronic GvHD, but mesenchymal stromal cells (MSCs) have shown substantial promise. MSCs promote an immunosuppressive and immunoregulatory environment via multifactorial mechanisms, including: secretion of proteins/peptides/hormones; transfer of mitochondria; and transfer of exosomes or microvesicles containing RNA and other molecules. A large number of clinical studies have investigated MSCs from various sources as a treatment for acute and/or chronic GvHD. MSCs are generally safe and well tolerated, and most clinical studies have generated encouraging efficacy results, but response rates have varied. Confounding factors include variability in MSC donor types, production methodology and dose regimens, as well as variations in study design. It is well-established that extensive culture expansion of primary donor-derived MSCs leads to marked changes in functionality, and that there is a high level of inter-donor variability in MSC properties. However, recent manufacturing innovations may be capable of overcoming these problems. Further adequately powered prospective studies are required to confirm efficacy and establish the place of MSC therapy in the treatment of this condition.

Acute Graft

Acute graft versus host disease (aGVHD) remains a leading cause of morbidity and mortality in allogeneic hematopoietic stem cell transplant (allo-HSCT). Tacrolimus (TAC), a calcineurin inhibitor that prevents T-cell activation, is commonly used as a GVHD prophylaxis. However, there is variability in the serum concentrations of TAC, and little is known on the impact of early TAC levels on aGVHD. We retrospectively analyzed 673 consecutive patients undergoing allo-HSCT at the Ohio State University between 2002 and 2016. Week 1 TAC was associated with a lower risk of aGVHD II–IV at TAC level ≥10.15 ng/mL (p = 0.03) compared to the lowest quartile. The cumulative incidence of relapse at 1, 3 and 5 years was 33%, 38% and 41%, respectively. TAC levels at week 2, ≥11.55 ng/mL, were associated with an increased risk of relapse (p = 0.01) compared to the lowest quartile. Subset analysis with acute myeloid leukemia and myelodysplastic syndrome patients showed significantly reduced aGVHD with TAC level ≥10.15 ng/mL at week 1 and a higher risk of relapse associated with week 2 TAC level ≥11.55 ng/mL (p = 0.02). Hence, achieving ≥10 ng/mL during the first week of HCT may mitigate the risk of aGVHD. However, levels (>11 ng/mL) beyond the first week may be associated with suppressed graft versus tumor effect and higher relapse.

Graft Versus Host

Allogeneic hematopoietic stem cell transplantation (HSCT) is most commonly a treatment for inborn defects of hematopoiesis or acute leukemias. Widespread use of HSCT, a potentially curative therapy, is hampered by onset of graft-versus-host disease (GVHD), classified as either acute or chronic GVHD. While the pathology of acute GVHD is better understood, factors driving GVHD at the cellular and molecular level are less clear. Mast cells are an arm of the immune system that are known for atopic disease. However, studies have demonstrated that they can play important roles in tissue homeostasis and wound healing, and mast cell dysregulation can lead to fibrotic disease. Interestingly, in chronic GVHD, aberrant wound healing mechanisms lead to pathological fibrosis, but the cellular etiology driving this is not well-understood, although some studies have implicated mast cells. Given this novel role, we here review the literature for studies of mast cell involvement in the context of chronic GVHD. While there are few publications on this topic, the papers excellently characterized a niche for mast cells in chronic GVHD. These findings may be extended to other fibrosing diseases in order to better target mast cells or their mediators for treatment of fibrotic disease.

Abstract Background Some patients with systemic juvenile idiopathic arthritis (SJIA) and severe, refractory disease achieved remission through intensive immunosuppressive treatment followed by autologous hematopoietic stem cell transplantation (HSCT). However, disease relapsed in most cases. More recently selected SJIA patients received allogenic HSCT from a HLA-identical sibling or a HLA matched unrelated donor. While most transplanted patients achieved sustained SJIA remission off-treatment, the procedure-related morbidity was high. Case report A girl presented SJIA with a severe disease course since the age of 15 months. She was refractory to the combination of methotrexate and steroids to anti-interleukin (IL)-1, then anti-IL-6, tumor necrosis factor alpha inhibitors, and thalidomide. Given the high disease burden and important treatment-related toxicity the indication for a haploidentical HSCT from her mother was validated, as no HLA matched donor was available. The patient received a T replete bone marrow graft at the age of 3.7 years. Conditioning regimen contained Rituximab, Alemtuzumab, Busulfan, and Fludarabine. Cyclophosphamide at D + 3 and + 4 post HSCT was used for graft-versus-host-disease prophylaxis, followed by Cyclosporin A and Mycophenolate Mofetil. Post HSCT complications included severe infections, grade 3 intestinal graft-versus-host-disease, autoimmune thyroiditis, and immune thrombocytopenia. Three years after HSCT, the child is alive and well, notwithstanding persistent hypothyroidy requiring substitution. Immune thrombocytopenia had resolved. Most importantly, SJIA was in complete remission, off immunosuppressive drugs. Conclusion Allogenic HSCT may be a therapeutic option, even with a HLA haplo-identical alternative donor, in patients with inflammatory diseases such as SJIA. Despite increased experience with this treatment, the risk of life-threatening complications restrains its indication to selected patients with severe, refractory disease.

Abstract Background Cytomegalovirus (CMV) is a serious complication following Hematopoietic Stem Cell Transplant (HSCT) and can lead to serious organ disease and mortality. This study aimed to investigate the association between absolute lymphocyte count (ALC) and CMV to determine whether ALC could help to identify those at an increased risk of CMV infection and recurrence Methods Adults undergoing HSCT between 2011 and 2016 at Rigshospitalet, Denmark were included. Cox proportional hazards models investigated risk factors, including ALC, for CMV infection in the first year post-transplant and recurrent CMV infection 6 months after clearance and stopping CMV treatment for the first infection. For the primary outcome ALC was investigated as a time-updated risk factor lagged by 7 days, and for recurrent CMV, ALC measured at the time at the time of stopping treatment for the first CMV infection was investigated (+/- 7 days). Results Of the 352 HSCT recipients included, 57% were male, 40% received myeloablative conditioning, 42% had high risk (D-R+) CMV IgG serostatus at transplant and the median age was 56 (IQR 43-63). 143 (40.6%) patients had an episode of CMV DNAemia a median of 47 days after transplant (IQR 35-62). A lower current ALC (≤ 0.3 x109/L) was associated with a higher risk of CMV infection in univariate analysis compared to a high current ALC (> 1 x109/L). However, this association was attenuated after adjustment, particularly for acute graft versus host disease (Figure). 102 HSCT recipients were investigated for risk of recurrent CMV of which 41 (40.2%) had a recurrent CMV episode a median of 27 days (IQR 16-50) after stopping CMV treatment for the first infection. A lower ALC (≤ 0.3 x109/L) at the time of stopping CMV treatment was associated with a significantly higher risk of recurrent CMV after adjustment (Figure). A higher peak viral load (> 1500 IU/ml) during the first episode of CMV infection was also associated with an increased risk of recurrent CMV (aHR 2.47, 95%CI 1.00-6.10 compared to < 750 IU/ml). Association between absolute lymphocyte count (ALC) and risk of CMV infection and recurrent CMV within 6 months. **First CMV infection multivariable model also adjusted for sex, CMV serostatus, age, year of transplant, Charlson Comorbidity Index, Anti-thymocyte globulin (ATG) given, HLA donor-recipient matching, and acute graft versus host disease (time-updated) *Recurrent CMV infection multivariable model also adjusted for conditioning regimen, sex, CMV serostatus, age, year of transplant Anti-thymocyte globulin (ATG) given, HLA donor-recipient matching, and acute graft versus host disease and peak CMV viral load during the first CMV infection Conclusion A lower ALC at the time of stopping treatment for the first CMV infection was associated with an increased risk of recurrent CMV and could be used to help guide decisions for augmented CMV surveillance and clinical awareness of CMV disease symptoms in these patients.

Post Transplant

Post-hematopoietic stem cell transplant secondary solid neoplasms are uncommon and usually host-derived. We describe a 6-year-old female who developed a mixed donor-recipient origin mesenchymal stromal tumor-like lesion in the liver following an unrelated hematopoietic stem cell transplant complicated by severe graft-versus-host disease. This lesion arose early post-transplant in association with hepatic graft-versus-host disease. At 12 years post-transplant, the neoplasm has progressively shrunken in size and the patient remains well with no neoplasm-associated sequelae. This report characterizes a novel lesion of mixed origin post-transplant and offers unique insights into the contribution of bone marrow-derived cells to extra-medullary tissues.
