Negative Effect

The choice of the optimal donor in the absence of an HLA-compatible relative, as well as the analysis of the risks of hematopoietic stem cell transplantation (HSCT), is extremely important, especially in patients with non-cancerous diseases. The article analyzes 99 allogeneic HSCTs from unrelated donors in the bone marrow transplantation department of the Russian Children’s Clinical Hospital. The analysis included patients with acquired and congenital forms of non-malignant diseases. The choice of an optimal unrelated donor in the absence of a compatible relative donor, as well as an analysis of the risks of treatment, requires studying the factors that influence the outcome of treatment in this group of patients. It was shown that the level of 2-year overall survival (OS) was 74 % (standard deviation ± 4.7 %). At the same time, clinical manifestations of the acute graft versus host disease of grade I–IV were recorded in 67 % (n = 66) of patients, and severe forms of grade III–IV in 13 % (n = 13) of children. Chronic graft versus host disease (chGVHD) was observed in 29 % (n = 29) patients. When studying the factors associated with the donor, it was found that the differences in the HLA system have a negative effect on the incidence of chGVHD; in a (9/10) HLA-incompatible donor, it was 29 % higher (p = 0.019). Increasing the age of the donor for every 10 years consistently reduces the OS by 9–11 % (p = 0.117), however, the OS with a donor over 46 years old was 100 % (n = 7). No effect on the agents with respect to the following factors with respect to the recipient was found: by sex, blood group, serostatus for cytomegalovirus (CMV). It was noted that the combination of CMV-positive serostatus of the donor and the negative status of the recipient increases the risk of transplant rejection up to 50 % in comparison with other variants of CMV serostatus (p = 0.001). In general, the possibility of performing HSCT from an unrelated donor for patients with non-malignant diseases and possible ways of selecting the optimal donor was noted. Conflict of interest.

Acute Graft

e19027 Background: Clostridiodes difficile infection (CDI) is reported to occur up to 9-fold higher in allogenic hematopoietic stem cell transplant (HSCT) recipients compared to the general population of hospitalized patients. This is attributed to disruption of gut microbiome by antibiotics, myeloablative regimens, neutropenia, prolonged hospitalization, and immunosuppressive regimens administered to prevent acute graft-versus-host disease (aGVHD). CDI by disruption of the intestinal microbiome may trigger gastrointestinal aGVHD. Previous studies from HSCT centers have reported conflicting data on the relationship between CDI and subsequent development of aGVHD. Methods: The Nationwide Readmissions Database was queried for admissions of adult allogenic HSCT patients between 2016 and 2018. Those with and without CDI during index admission were compared. Multivariable logistic regression was used to evaluate the primary outcome of risk of aGVHD in the index admission or within 100 days post-engraftment. Results: A total of 13518 allogenic HSCT patients were included in the study. Mean age was 52.4 years. 57.2% of patients were female. The most common underlying diagnoses were acute myeloid leukemia (38%), myelodysplastic syndrome (17%) and acute lymphoblastic leukemia (14%). 11.1% of the index admissions were complicated by CDI. Rates of aGVHD during the index admission or 100 days post-engraftment were similar between CDI and non-CDI groups: 13.8% vs. 12.1%, p=0.19 during index admission and 29.2% vs. 26.1%, p=0.09 during 100 days post-engraftment. Nonetheless, patients with CDI had longer length of hospital stay (34.6 vs 29.8 days, p<0.0001), higher hospitalization costs ($608K vs $506K USD) and greater rate of inpatient mortality (7.3% vs 4.6%, p<0.001). In the multivariate regression analysis, CDI during index admission was not associated with risk of development of aGVHD (Adjusted Odds Ratio 1.14, 95% Confidence Interval 0.87-1.48, p=0.34). Age and unrelated donor HSCT were predictive of risk of aGVHD. Conclusions: CDI during index admission was not predictive of aGVHD during the first 100 days post-allogenic HSCT. HSCT patients are frequency colonized with C.difficile. Diarrhea secondary to CDI may resemble gastrointestinal aGVHD. Therefore, overdiagnosis of CDI in this population is a concern. Antimicrobial stewardship and use of clinical decision support tools have been advocated recently to decrease testing of HSCT patients with C.difficile colonization.

Abstract We herein document a complete response of extensive chronic graft-versus-host disease (cGvHD) to a Bruton's tyrosine kinase (BTK) inhibitor, ibrutinib. A 41 years old female with primary refractory MCL underwent mismatched unrelated donor (MMUD) allogeneic hematopoietic stem cell transplantation in December 2011 (conditioning with CY/TBI and alemtuzumab, graft=6.6x 106/kg CD-34+ cells, tacrolimus alone for GVHD prevention). Following engraftment on day 11, she developed grade III acute GvHD involving the skin and gut on day 17 of transplantation that persisted beyond 100 days post-transplant. Her cGvHD was treated with steroids, but remained active and extensive. Despite persistent cGvHD and 100% donor chimerism she relapsed in July 2012. Treatment with radiation and bendamustine with rituximab failed. By December 2013, the patient had extensive cGvHD manifesting as scleromatous skin thickening, oral ulcers and sclerosis of the buccal mucosa, ocular dryness and diarrhea, and was started on ibrutinib1 560 mg once daily for relapsed MCL. After 8 weeks of therapy, cGvHD had begun to improve. Oral steroids were reduced and ultimately stopped after 26 weeks of ibrutinib; after 30 weeks treatment all cGvHD manifestations resolved completely. A complete remission for MCL was documented at 8 weeks of ibrutinib initiation. Currently she continues to be on 560 mg daily ibrutinib without cGvHD exacerbation or MCL relapse for 22 weeks and 52 weeks, respectively. Chronic graft versus host disease (cGvHD) is mediated donor T cells. The role of B cells in the pathogenesis of cGvHD is increasingly recognized. Two murine studies have explored the role of ibrutinib in cGVHD-like syndromes, one in which there is T cell driven sclerodermatous cGvHD and a second in which there is Ab driven multiorgan system cGvHD that includes bronchiolitis obliterans (BO). Administration of ibrutinib decreased the incidence and severity of sclerodermatous, and improved pre-existing lesions and also improved pulmonary fibrosis and reduced BO. Animals lacking BTK and ITK did not develop cGVHD, indicating that these molecules are critical to cGVHD development. Our report provides the evidence that BTK inhibition led to complete resolution of cGvHD and supports exploration of its role in future clinical trials.

Abstract Calcineurin inhibitors form the backbone of graft versus host disease (GVHD) prophylaxis in hematopoietic stem cell transplantation. In the adult literature tacrolimus was demonstrated superior to cyclosporine in preventing grade II–IV acute GVHD in both related and unrelated donor transplants; however, there is no data comparing their efficacy in the pediatric population. In a multi-institutional trial, we prospectively evaluated the clinical data on 102 patients receiving either cyclosporine/methotrexate or tacrolimus/methotrexate based prophylactic regimens for 6/6 matched unrelated donor, transplant. Conditioning regimens were fully ablative; no T-cell depletion was permitted; cord blood donors were excluded. Patients were required to receive either cyclosporine or tacrolimus, but the choice was per investigator preference. The two arms were reasonably balanced: 59.8% of patients received cyclosporine and 40.2% of patients received tacrolimus. Rates for maximum grade II–IV acute GVHD were 37.7% for cyclosporine and 39% for tacrolimus (p = 0.89). Rates for maximum grade III–IV acute GVHD were 19.6% for cyclosporine and 24.4% for tacrolimus (p = 0.57). Incidence of chronic GVHD in 97 evaluable patients was 37.9% in 58 patients who received cyclosporine and 35.8% in 39 patients who received tacrolimus (p = 0.84). Survival at 1 year post-transplant was similar in both groups: 59.2% for cyclosporine and 51.2% for tacrolimus (p= 0.31). Toxicity analysis is ongoing. In pediatric matched unrelated donor transplantation, the efficacy of tacrolimus/methotrexate and cyclosporine/methotrexate based regimens for prophylaxis of GVHD are not significantly different.

Abstract To reduce the morbidity and mortality associated with unrelated donor bone marrow (BM) transplantation and potentially extend the pool of suitable donors, cryopreserved unrelated donor umbilical cord blood was considered as an alternate source of hematopoietic stem cells for transplantation. Patients with leukemia, BM failure syndrome, or inborn error of metabolism were eligible for a phase I clinical trial designed to estimate the risk of graft failure and severe acute graft-versus- host disease after transplantation of umbilical cord blood from unrelated donors. As of December 21, 1995, unrelated donor umbilical cord blood was used to reconstitute hematopoiesis in eighteen patients aged 0.1 to 21.3 years weighing 3.3 to 78.8 kg with acquired or congenital lympho-hematopoietic disorders or metabolic disease. Patients received either HLA-matched (n = 7) or HLA-1 to 3 antigen disparate (n = 11) grafts collected and evaluated by the New York Blood Center (New York, NY). The probability of engraftment after unrelated donor umbilical cord blood transplantation was 100% with no patient having late graft failure to date. The probability of grade III-IV acute graft-versus-host disease at 100 days was 11%. With a median follow-up of 6 months (range, 1.6 to 17 months); the probability of survival at 6 months is 65% in this high risk patient population. We conclude that cryopreserved umbilical cord blood from HLA-matched and mismatched unrelated donors is a sufficient source of transplantable hematopoietic stem cells with high probability of donor derived engraftment and low risk of refractory severe acute graft-versus-host disease. Limitations with regard to recipient size and degree of donor HLA disparity remain to be determined.

Abstract Although graft-versus-host disease (GVHD) is a life-threatening complication of hematopoietic stem-cell transplantation (HSCT), its current diagnosis depends mainly on clinical manifestations and invasive biopsies. Specific biomarkers for GVHD would facilitate early and accurate recognition of this grave condition. Using proteomics, we screened for plasma proteins specific for GVHD in a mouse model. One peak with 8972-Da molecular mass (m/z) retained a discriminatory value in 2 diagnostic groups (GVHD and normal controls) with increased expression in the disease and decreased expression during cyclosporin A treatment, and was barely detectable in syngeneic transplantation. Purification and mass analysis identified this molecule as CCL8, a member of a large chemokine family. In human samples, the serum concentration of CCL8 correlated closely with GVHD severity. All non-GVHD samples contained less than 48 pg/mL (mean ± SE: 22.5 ± 5.5 pg/mL, range: 12.6-48.0 pg/mL, n = 7). In sharp contrast, CCL8 was highly up-regulated in GVHD sera ranging from 52.0 to 333.6 pg/mL (mean ± SE: 165.0 ± 39.8 pg/mL, n = 7). Strikingly, 2 patients with severe fatal GVHD had extremely high levels of CCL8 (333.6 and 290.4 pg/mL. CCL8 is a promising specific serum marker for the early and accurate diagnosis of GVHD.

Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative treatment for different spectrum of diseases. This type of treatment is constantly improving, but HSCT remains a risky procedure with various possible complications, the main is – chronic “graft versus host” disease (cGVHD). сGVHD is immune disregulation, and characterized by a variety of clinical manifestations that reflect the multiple underlying pathophysiology mechanisms. The study of cGVHD has now made great progress, but there’s still a lot of questions. General characteristics, risk-factors of development, clinical manifestations, pathogenesis of cGVHD will be discussed in this article. Clinical case presented in this article explains usage of basic and novel agents for cGVHD treatment, prevention criterions for treatment of cGVHD in children.

Abstract Objective: To investigate the clinical manifestation, pathological features, management and prognosis of chronic graft-versus-host disease (cGVHD)-related membranous nephropathy following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: Clinical and pathological data from 3 patients with nephrotic syndrome following allo-HSCT were retrospectively analyzed. Results: cGVHD-related membranous nephropathy occurred in 3 out of 150 patients (2%) undergoing allo-HSCT in our BMT unit. 3 patients, with two male and one female, median age of 15 years, and median interval of 11 months between diagnosis and post-transplantation, typically presented with full nephrotic syndrome, including heavy proteinuria (median 8.1 g/24h), edema, hypoalbuminemia (median 29.6 g/L), and hypercholesterolemia (median 11.7 mmolL). A major finding of renal biopsy that was consistent with membranous nephropathy in early stage was diffusely thickened glomerular basement membranes (GBMs) with deposits of IgG along it. All patients showed evidence of cGVHD. Two patients responded well to steroid, with gradual improvement of clinical symptoms and disappearance of proteinuria, and are still alive without evidence of relapse. But the other one died of disseminated hemorrhagic varicella one month following immunosuppressive therapy. Conclusion: These findings suggest that the kidney may be the target organ of alloimmunity, and membranous nephropathy may be one of clinical manifestations of cGVHD, which is response to steroid, resulting in disappearance of proteinuria. It is necessary for transplant physicians to keep in mind the possibility of cGVHD-related membranous nephropathy when a case of nephritic syndrome is encountered.

Graft Versus Host

Chronic graft versus host disease (GVHD) is a significant cause of morbidity and mortality in matched unrelated donor hematopoietic stem cell transplantation. Incidence of acute GVHD is a major risk factor for chronic GVHD. Calcineurin inhibitors form the backbone of graft versus host disease (GVHD) prophylaxis in hematopoietic stem cell transplantation. When comparing cyclosporine to tacrolimus for GVHD prophylaxis, we previously reported a trend toward superiority of cyclosporine as prophylaxis against acute GVHD. We now analyze their effect on the incidence and severity of chronic GVHD. In a multi-institutional trial, we prospectively collected the clinical data on 141 evaluable patients receiving either cyclosporine/methotrexate or tacrolimus/methotrexate based prophylactic regimens for 6/6 matched unrelated donor, transplant. Conditioning regimens were fully ablative; no T-cell depletion was permitted; cord blood donors were excluded. Patients were required to receive either cyclosporine or tacrolimus, but the choice was per investigator preference. The two arms were reasonably balanced: 60.1% of patients received cyclosporine and 39.9% of patients received tacrolimus. Rates for acute GVHD were 60.4% for cyclosporine and 73.8% for tacrolimus (p = 0.086). Rates for chronic GVHD were 44.2% for cyclosporine and 47.3% for tacrolimus (p = 0.7). In the 61 patients with chronic GVHD, extensive disease was present in 82.9% of cyclosporine group and 80.8% of the tacrolimus group (p = 1.0) Those graded as moderate or severe comprised 80% of the cyclosporine group and 56% of the tacrolimus group (p = 0.46) and those both extensive and moderate or severe were 71.4% and 52%, respectively (p = 0.12). In pediatric matched unrelated donor transplantation, the incidence and severity of chronic graft versus host disease in patients receiving either tacrolimus/methotrexate or cyclosporine/methotrexate based regimens for prophylaxis of GVHD are not significantly different.

Abstract Ruxolitinib (RUX) is an oral selective Janus-associated kinase 1 (JAK1) and JAK2 inhibitor that is approved by the FDA for the treatment of patients with myeloproliferative neoplasms. JAKs transmit the signaling of ligand binding to inflammatory cytokine receptors into intracellular responses, and inhibition of JAK is effective in the treatment of autoimmune disorders. In MHC-mismatched mouse transplant models, pharmacologic inhibition of IFNγR signaling with RUX reduced graft-versus-host disease (GVHD) and improved survival (Choi et al Blood 2012); and preliminary reports have shown that 13/14 patients with steroid-refractory acute (10) and chronic (4) GVHD responded to RUX therapy. (Sporell et al Blood 2014). Between 09/2014 and 7/2015, 16 patients (12M/4F), with hematological malignancies and recipients of unrelated donor (14), matched sibling (2) blood (15) or marrow (1) transplant developed quiescent (12) or de novo (4) severe (NIH criteria) steroid-dependent cGVHD and received RUX as 2nd (4), 3d (7) 4th (4) or 5th (1) line salvage. 12 had prior grades 1 (3) 2 (6) 3(2) or 4 (1) acute GVHD that affected the skin (12) and gastrointestinal system (GI, 5). Median time of onset of cGVHD was d+130 (range, 90-299), and affected skin (16) eyes (12), mouth (10), GI (8), lungs (4), liver (3) and the musculoskeletal system (3). cGVHD was steroid dependent with recurrences of cGVHD symptoms with steroid tapers that were attempted a median of 4 times(range, 2-10). Median duration of continuous exposure to steroids for cGVHD was 24 months (range, 6-53). RUX was administered at the dose of 5 mg BID. Median weight was 82 kg (range, 56-158). RUX dose was increased to 15 mg/d (4) or 20 mg/d (3) due to physician preference (4), patient weight (1), or flare of cGVHD after initial response due to discontinuation of immunosuppression (1) or temporary perioperative hold of RUX (1). Median duration of RUX therapy was 6 months (range 1-14). All patients were evaluable for response. Complete resolution of clinical manifestations of cGVHD was observed in the following organs: lungs (dyspnea/O2 dependence), mouth (oral ulcerations), skin (non-sclerodermatous erythema), liver (sGOT, sGPT, alkaline phosphatase), musculoskeletal and GI (dysphagia, diarrhea). Subjective improvement was reported in sclerodermatous and ocular cGVHD. Responses were observed early after initiation of RUX (median 14 days). Prednisone was successfully reduced to physiologic doses (n=2) or discontinued (n=10) in 12 (75%), and taper is currently in progress for the 4 patients who started RUX in the past 8 weeks. Median time from initiation of RUX to prednisone discontinuation was 72 days (range, 31-120). With a median follow-up of 4 months (range, 1-12) from prednisone discontinuation/reduction to physiologic doses, 2 patients experienced a transient flare of cGVHD symptoms associated with discontinuation of immunosuppression (1) and temporary hold of RUX. None of the other patients required a restart of prednisone or increased immunosuppression. We conclude that RUX is an effective steroid-sparing agent in steroid-dependent severe cGVHD. Validation of these results in prospective trials is needed. Disclosures Jillella: Seattle Genetics, Inc.: Research Funding.

Purpose HLA-mismatched unrelated donor (MMUD) hematopoietic stem-cell transplantation (HSCT) is associated with increased graft-versus-host disease (GVHD) and impaired survival. In reduced-intensity conditioning (RIC), neither ex vivo nor in vivo T-cell depletion (eg, antithymocyte globulin) convincingly improved outcomes. The proteasome inhibitor bortezomib has immunomodulatory properties potentially beneficial for control of GVHD in T-cell-replete HLA-mismatched transplantation. Patients and Methods We conducted a prospective phase I/II trial of a GVHD prophylaxis regimen of short-course bortezomib, administered once per day on days +1, +4, and +7 after peripheral blood stem-cell infusion plus standard tacrolimus and methotrexate in patients with hematologic malignancies undergoing MMUD RIC HSCT. We report outcomes for 45 study patients: 40 (89%) 1-locus and five (11%) 2-loci mismatches (HLA-A, -B, -C, -DRB1, or -DQB1), with a median of 36.5 months (range, 17.4 to 59.6 months) follow-up. Results The 180-day cumulative incidence of grade 2 to 4 acute GVHD was 22% (95% CI, 11% to 35%). One-year cumulative incidence of chronic GVHD was 29% (95% CI, 16% to 43%). Two-year cumulative incidences of nonrelapse mortality (NRM) and relapse were 11% (95% CI, 4% to 22%) and 38% (95% CI, 24% to 52%), respectively. Two-year progression-free survival and overall survival were 51% (95% CI, 36% to 64%) and 64% (95% CI, 49% to 76%), respectively. Bortezomib-treated HLA-mismatched patients experienced rates of NRM, acute and chronic GVHD, and survival similar to those of contemporaneous HLA-matched RIC HSCT at our institution. Immune recovery, including CD8+ T-cell and natural killer cell reconstitution, was enhanced with bortezomib. Conclusion A novel short-course, bortezomib-based GVHD regimen can abrogate the survival impairment of MMUD RIC HSCT, can enhance early immune reconstitution, and appears to be suitable for prospective randomized evaluation.
