    Risk factors for non-Aspergillus mold infection (NAMI) and the impact on transplant outcome are poorly assessed in the current era of antifungal agents. Outcomes of 124 patients receiving allogeneic HCT diagnosed with either mucormycosis [n=72] or fusariosis [n=52] between days 0-365 after HCT are described and compared to a control cohort (n=11856). Patients with NAMI had more advanced disease [mucormycois 25%, fusariosis 23%, controls 18%; p = 0.004] and were more likely to have a KPS<90% at HCT [mucormycosis 42%, fusariosis 38%, controls 28%; p=0.048]. The 1-year survival after HCT was 22% (15–29%) for cases and was significantly inferior compared to controls [65%(64–65%); p < 0.001]. Survival from infection was similarly dismal regardless of mucormycosis [15% (8-25%)] and fusariosis [21% (11-33%)]. In multivariable analysis, NAMI was associated with a 6-fold higher risk of death (p<0.0001) regardless of the site or timing of infection. Risk factors for mucormycosis include preceding acute GVHD, prior aspergillus infection, and older age. For fusariosis, increased risks including receipt of cord blood, prior CMV infection, and transplant prior to May 2002. In conclusion, NAMI occurs infrequently, is associated with high mortality, and appears with similar frequency in the current antifungal era. PMID:26524262

    We have reported a lower incidence of acute graft versus host disease (aGVHD) with a novel conditioning regimen using low dose rabbit anti-thymocyte globulin (TG, Thymoglobulin) with fludarabine and intravenous busulfan (FluBuTG). To assess further this single center experience, we performed a retrospective matched pair analysis comparing outcomes of adult patients transplanted using the FluBuTG conditioning regimen with matched controls from patients reported to the CIBMTR receiving a first allogeneic hematopoietic stem cell transplant (HCT) after standard oral busulfan and cyclophosphamide (BuCy). 120 cases and 215 matched controls were available for comparison. Patients receiving FluBuTG had significantly less treatment related mortality (12% vs 34%, p<0.001) and grades II–IV aGVHD (15% vs 34% p<0.001) compared to BuCy patients. The risk of relapse was higher in the FluBuTG patients (42% vs 20%, p<0.001). The risks of chronic GVHD (cGVHD) and disease free survival (DFS) were similar in the cases and controls. These results suggest that the novel regimen FluBuTG decreases the risk of aGVHD and transplant mortality after HLA-identical sibling HCT, but is associated with an increased risk of relapse, resulting in similar DFS. Whether these conditioning regimens may be more suitable for specific patient populations based on relapse risk requires testing in prospective randomized trials. PMID:18721762

    A second allogeneic hematopoietic cell transplantation (HCT) is the sole salvage option for individuals who develop graft failure after their first HCT. Data on outcomes after second HCT in patients with Fanconi anemia (FA) are scarce. Here we report outcomes after second allogeneic HCT for FA (n = 81). The indication for second HCT was graft failure after the first HCT. Transplantations were performed between 1990 and 2012. The timing of the second HCT predicted subsequent graft failure and survival. Graft failure was high when the second HCT was performed less than 3 months from the first. The 3-month probability of graft failure was 69% when the interval between the first HCT and second HCT was less than 3 months, compared with 23% when the interval was longer (P < .001). Consequently, the 1-year survival rate was substantially lower when the interval between the first and second HCTs was less than 3 months compared with longer (23% vs 58%; P = .001). The corresponding 5-year probability of survival was 16% and 45%, respectively (P = .006). Taken together, these data suggest that fewer than one-half of patients with FA undergoing a second HCT for graft failure are long-term survivors. There is an urgent need to develop strategies to reduce the rate of graft failure after first HCT. PMID:26116087

    Outcomes in patients with acute promyelocytic leukemia have improved; however, a subset of patients relapse despite receiving all-trans-retinoic acid and/or arsenic-based therapies. Among 40 patients with acute promyelocytic leukemia who were treated at our institution (1980–2010), 24 received hematopoietic stem cell transplantation (HCT) (autologous HCT, 7; allogeneic HCT, 14; both, 3); 16 received chemotherapy only. All 3 strategies (autologous HCT, allogeneic HCT, chemotherapy) were feasible in patients with relapsed acute promyelocytic leukemia and result in long-term disease control in selected patients. Background Outcomes in patients with acute promyelocytic leukemia (APL) have improved; however, a significant number of patients still relapse despite receiving all-trans-retinoic acid (ATRA) and arsenic-based therapies. Patients and Methods Outcomes of patients with relapsed APL who were treated at our institution (1980–2010) and who received HCT were compared with those who received chemotherapy (CT) only. Results Among 40 patients, 24 received HCT (autologous [auto] HCT, 7; allogeneic [allo] HCT, 14; both, 3); 16 received CT only. The median age at diagnosis was 36 years (range, 13–50 years), 31 years (range, 16–58 years), and 44 years (range, 24–79 years) for the auto-HCT, allo-HCT, and CT groups, respectively. Ten (100%) patients who received auto-HCT and 12 (71%) who received allo-HCT were in complete remission at the time of the HCT. The median follow-ups in the auto-HCT, allo-HCT, and CT groups were 74 months (range, 26–135 months), 118 months (range, 28–284 months), and 122 months (range, 32–216 months), respectively. Transplantation-related mortality (1 year) after auto-HCT and allo-HCT were 10% and 29%, respectively. The 7-year event-free survival after auto-HCT and allo-HCT was 68.6% and 40.6%, respectively (P = .45). The 7-year overall survival was 85.7%, 49.4%, and 40% in the auto-HCT, allo-HCT, and CT groups, respectively (P

    For diffuse large B-cell lymphoma (DLBCL) patients progressing after autologous haematopoietic cell transplantation (autoHCT), allogeneic HCT (alloHCT) is often considered, although limited information is available to guide patient selection. Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we identified 503 patients who underwent alloHCT after disease progression/relapse following a prior autoHCT. The 3-year probabilities of non-relapse mortality, progression/relapse, progression-free survival (PFS) and overall survival (OS) were 30, 38, 31 and 37% respectively. Factors associated with inferior PFS on multivariate analysis included Karnofsky performance status (KPS) <80, chemoresistance, autoHCT to alloHCT interval <1-year and myeloablative conditioning. Factors associated with worse OS on multivariate analysis included KPS<80, chemoresistance and myeloablative conditioning. Three adverse prognostic factors were used to construct a prognostic model for PFS, including KPS<80 (4 points), autoHCT to alloHCT interval <1-year (2 points) and chemoresistant disease at alloHCT (5 points). This CIBMTR prognostic model classified patients into four groups: low-risk (0 points), intermediate-risk (2-5 points), high-risk (6-9 points) or very high-risk (11 points), predicting 3-year PFS of 40, 32, 11 and 6%, respectively, with 3-year OS probabilities of 43, 39, 19 and 11% respectively. In conclusion, the CIBMTR prognostic model identifies a subgroup of DLBCL patients experiencing long-term survival with alloHCT after a failed prior autoHCT. PMID:26989808

    Non-Hodgkin lymphoma (NHL) constitutes a collection of lymphoproliferative disorders with widely varying biological, histological, and clinical features. For the B cell NHLs, great progress has been made due to the addition of monoclonal antibodies and, more recently, other novel agents including B cell receptor signaling inhibitors, immunomodulatory agents, and proteasome inhibitors. Autologous hematopoietic cell transplantation (auto-HCT) offers the promise of cure or prolonged remission in some NHL patients. For some patients, however, auto-HCT may never be a viable option, whereas in others, the disease may progress despite auto-HCT. In those settings, allogeneic HCT (allo-HCT) offers the potential for cure. Over the past 10 to 15 years, considerable progress has been made in the implementation of allo-HCT, such that this approach now is a highly effective therapy for patients up to (and even beyond) age 75 years. Recent advances in conventional lymphoma therapy, peritransplantation supportive care, patient selection, and donor selection (including the use of alternative hematopoietic cell donors), has allowed broader application of allo-HCT to patients with NHL. As a result, an ever-increasing number of NHL patients over age 60 to 65 years stand to benefit from allo-HCT. In this review, we present data in support of the use of allo-HCT for patients with diffuse large B cell lymphoma, follicular lymphoma, and mantle cell lymphoma. These histologies account for a large majority of allo-HCTs performed for patients over age 60 in the United States. Where possible, we highlight available data in older patients. This body of literature strongly supports the concept that allo-HCT should be offered to fit patients well beyond age 65 and, accordingly, that this treatment should be covered by their insurance carriers.

    Quality of life (QOL) is increasingly recognized as an important clinical outcome of hematopoietic cell transplantation (HCT), but patient education is often overlooked. The goal of the current qualitative study was to examine education regarding post-HCT QOL from the patient’s perspective. Allogeneic HCT recipients participated in one of four focus groups. Participants were asked to recall what they had been told about post-HCT QOL as they were preparing for transplant, how their QOL differed from what they expected, and how to educate future patients about post-HCT QOL. Verbatim transcripts were coded for both a priori and emergent themes using content analysis. A total of 24 patients participated (54% female, mean age 51, range 23-73). Participants frequently expressed the desire for additional education regarding post-HCT QOL, particularly late complications. They noted that late complications were often unexpected, had a profound impact on their QOL, and threatened their ongoing sense of recovery. They emphasized that the timing, content, and format of education regarding QOL should be flexible to meet their diverse needs. Findings from the current study draw attention to the importance of patient education regarding post-HCT QOL as well as additional QOL research designed with patient education in mind. PMID:24121210

    Elderly patients (>60 years) with acute myeloid leukemia have a poor prognosis with a chemotherapy-alone approach. Allogeneic hematopoietic-cell transplantation (HCT) can improve overall survival (OS). However, myeloablative regimens can have unacceptably high transplant-related mortality (TRM) in an unselected group of older patients. Reduced-intensity conditioning (RIC) or nonmyeloablative (NMA) conditioning regimens preserve the graft-versus-leukemia effects but reduce TRM. NMA regimens result in minimal cytopenia and may not require stem cell support for restoring hematopoiesis. RIC regimens, intermediate in intensity between NMA and myeloablative regimens, can cause prolonged myelosuppresion and usually require stem cell support. A few retrospective and prospective studies suggest a possibility of lower risk of relapse with myeloablative HCT in fit older patients with lower HCT comorbidity index; however, RIC and NMA HCTs have an important role in less-fit patients and those with significant comorbidities because of lower TRM. Whether early tapering of immunosuppression, monitoring of minimal residual disease, and post-transplant maintenance therapy can improve the outcomes of RIC and NMA HCT in elderly patients will require prospective trials.

    Allogeneic hematopoietic cell transplantation (HCT) offers curative therapy for many patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). However, post-HCT relapse remains a major problem, particularly in patients with high-risk cytogenetics. In this prospective phase II trial we assessed the efficacy and toxicity of treosulfan, fludarabine and 2 Gy total body irradiation (TBI) as conditioning for allogeneic HCT in patients with MDS or AML. Ninety-six patients with MDS (n=36; 15 RMCD; 10 RAEB-1; 10 RAEB-2; 1 CMML-1) or AML (n=60; 35 CR1; 18 CR2; 3 advanced CR; 4 refractory relapse) were enrolled; median age was 51 (range: 1–60) years. Twelve patients had undergone a prior HCT with high intensity conditioning. Patients received intravenous (IV) treosulfan, 14 g/m2/day on days −6 to −4, IV fludarabine, 30 mg/m2/day on days −6 to −2, and 2 Gy TBI on day 0, followed by infusion of hematopoietic cells from related (n=27) or unrelated (n=69) donors. Graft-vs.-host disease prophylaxis consisted of tacrolimus and methotrexate. With a median follow-up of 30 months, the 2-year overall survival (OS), relapse incidence and non-relapse mortality were 73%, 27% and 8%, respectively. The incidences of grades II–IV (III–IV) acute and chronic graft-versus-host disease were 59% (10%) and 47%, respectively. Two-year OS was not significantly different between MDS patients with poor risk and good/intermediate risk cytogenetics (69% and 85%, respectively), or between AML patients with unfavorable and favorable/intermediate risk cytogenetics (64% and 76%, respectively). In AML patients, minimal residual disease (MRD; n=10) at the time of HCT predicted higher relapse incidence (70% vs. 18%) and lower OS (41% vs. 79%) at 2 years, when compared to patients without MRD. In conclusion, treosulfan, fludarabine and low-dose TBI provided effective conditioning for allogeneic HCT in patients with MDS or AML, and resulted in low relapse incidence, regardless

    Acute myeloid leukemia (AML) relapse after allogeneic hematopoietic cell transplantation (alloHCT) remains a major therapeutic challenge. We studied outcomes of 1788 AML patients relapsing after alloHCT (1990–2010) during first or second complete remission (CR) to identify factors associated with longer post-relapse survival. Median time of post HCT relapse was 7 months (mo; range, 1–177). At relapse, 1231 patients (69%) received intensive therapy, including chemotherapy (CT) alone (n=660), donor lymphocyte infusion (DLI)±CT (n=202; %), or 2nd alloHCT±CT ±DLI (n=369), with subsequent CR rates of 29%. Median follow-up after relapse was 39 mo (range, <1–193). Survival for all patients was 23% at 1 year post-relapse; however, 3-yr overall survival correlated with time from HCT to relapse (4% for relapse during 1–6 mo period, 12% during 6 mo-2 yr, 26% during 2–3 yr, and 38% for ≥3 yr). In multivariable analysis, lower mortality was significantly associated with longer time from alloHCT to relapse (RR 0.55 for 6 mo-2 yr, RR 0.39 for 2–3 yr, and RR 0.28 for ≥3 yr; p<0.0001) and a 1st HCT using reduced-intensity conditioning (RR=0.77; 95% CI 0.66–0.88, p=0.0002). In contrast, inferior survival was associated with age >40 yr (RR=1.42, 95% CI 1.24–1.64; p<0.0001), active GVHD at relapse (RR=1.25, 95% CI 1.13–1.39; p<0.0001), adverse cytogenetics (RR=1.37, 95% CI 1.09–1.71; p=0.0062), mismatched URD (RR=1.61, 95% CI 1.22–2.13; p=0.0008), and use of cord blood for 1st HCT (RR=1.23, 95% CI 1.06–1.42; p=0.0078). AML relapse after alloHCT predicted poor survival; however, patients who relapsed ≥6 mo after their initial alloHCT had better survival and may benefit from intensive therapy such as 2nd alloHCT±DLI.

    Liver injury is a frequent, serious complication of allogeneic hematopoietic cell transplantation (HCT) following myeloablative preparative regimens. We sought to determine the frequency and severity of hepatic injury after nonmyeloablative conditioning and its relationship to outcomes. One hundred ninety-three consecutive patients who received 2 Gy total body irradiation with or without fludarabine were evaluated for end points related to liver injury. Patients with diseases treatable by HCT who were ineligible for conventional myeloablative allogeneic HCT because of advanced age and/or comorbid conditions were included. Fifty-one patients (26%) developed hyperbilirubinemia of 68.4 microM (4 mg/dL) or greater, most commonly resulting from cholestasis due to graft-versus-host disease (GVHD) or sepsis. Pretransplantation factors associated with liver dysfunction were a diagnosis of aggressive malignancy (hazard ratio [HR] 1.9; P =.04) and the inclusion of fludarabine in the conditioning regimen (HR 1.8; P =.07). Overall survival at 1 year was superior for patients who had maximal serum bilirubin levels in the normal (78%) or minimally elevated (22.23-66.69 microM [1.3-3.9 mg/dL]) ranges (69%) compared with those in the 68.4 to 117.99 microM (4-6.9 mg/dL; 20%), 119.7 to 169.29 microM (7.0-9.9 mg/dL; 17%), and 171.0 microM (10 mg/dL; 19%) or greater groups. In summary, significant jaundice occurred in 26% of patients and was predominantly due to cholestasis resulting from GVHD and/or sepsis. Aggressive malignancies (mainly advanced disease) and later development of jaundice after transplantation predicted inferior survival. PMID:12969980

    Brentuximab vedotin induces an overall response rate of 75% in patients with relapsed/refractory Hodgkin lymphoma, but its impact on future allogeneic transplantation (allo-HCT) is not known. We retrospectively examined the records of 18 patients with relapsed/refractory Hodgkin lymphoma who were treated on brentuximab vedotin clinical trials to evaluate the efficacy and safety of subsequent reduced-intensity allo-HCT. Seventeen patients had previous autologous transplant; 6 were in complete remission, and 8 were in partial remission before allo-HCT with 12 grafts from unrelated or mismatched donors. The 1-year overall survival was 100%, progression-free survival was 92.3%, and nonrelapse mortality was 0% (median follow-up, 14 months). The incidence of acute GVHD was 27.8% and chronic GVHD was 56.3%. Brentuximab vedotin before reduced-intensity allo-HCT does not appear to adversely affect engraftment, GVHD, or survival and may provide sufficient disease control to enable reduced-intensity allo-HCT.

    Natural killer (NK) cells can alter the outcome of hematopoietic cell transplantation (HCT) if donor alloreactivity targets the recipient. Since most NK cells express inhibitory killer-immunoglobulin receptors (KIRs), we hypothesized that the susceptibility of recipient cells to donor NK cell–mediated lysis is genetically predetermined by the absence of known KIR ligands. We analyzed data from 2062 patients undergoing unrelated donor HCT for acute myeloid leukemia (AML; n = 556), chronic myeloid leukemia (CML; n = 1224), and myelodysplastic syndrome (MDS; n = 282). Missing 1 or more KIR ligands versus the presence of all ligands protected against relapse in patients with early myeloid leukemia (relative risk [RR] = 0.54; n = 536, 95% confidence interval [CI] 0.30-0.95, P = .03). In the subset of CML patients that received a transplant beyond 1 year from diagnosis (n = 479), missing a KIR ligand independently predicted a greater risk of developing grade 3-4 acute graft-versus-host disease (GVHD; RR = 1.58, 95% CI 1.13-2.22; P = .008). These data support a genetically determined role for NK cells following unrelated HCT in myeloid leukemia. PMID:17317850

    Excess body iron could persist for years after allogeneic hematopoietic cell transplantation (HCT) with possible deleterious sequels. An iron depletive therapy with phlebotomy seems rational. Kinetics of iron removal by phlebotomy without erythropoietin support in non-thalassemic adult patients with iron overload after HCT and the impact of pre- and post-HCT hemochromatosis (HFE) genotype on iron mobilization were investigated. Patients and methods: Phlebotomy was initiated in 61 recipients of allografts due to hematologic malignancies (median age 48 years) after a median of 18 months. The prephlebotomy median serum ferritin (SF) was 1697ng/ml and the median number of blood transfusions 28 units. Alanine aminotransferase (ALT)/aspartate aminotransferase (AST), alkaline phosphates (AP), and bilirubin were elevated in 55.7%, 64% and 11.5% patients respectively. HFE-genotype was elucidated by polymerase chain reaction using hybridization probes and melting curve analysis. Results: Phlebotomy was well-tolerated irrespective of age or conditioning. A negative iron balance in 80% of patients (median SF 1086 ng/ml) and a rise in hemoglobin were observed (p<0.0001). Higher transfusional burden and SF were associated with a greater iron mobilization per session (p=0.02). In 58% of patients, a plateau after an initial steady decline in SF was followed by a second decline under further phlebotomy. The improvement in ALT (p=0.002), AST (p=0.03), AP (p=0.01), and bilirubin (p<0.0001) did not correlate with the decline in SF. Mutant HFE-gene variants were detected in 14/55 (25%) pre-HCT and 22/55 (40%) patients post-HCT. Overall, dissimilar pre- and posttransplantational HFE-genotypes were detected in 20/55 (40%) patients. Posttransplantational mutant HFE variants correlated with a slower decline in SF (p=0.007). Conclusions: Phlebotomy is a convenient therapy of iron overload in survivors of HCT. A negative iron balance and a rise in hemoglobin were observed in the majority of

    Currently, the indications to perform reduced-intensity conditioning allogeneic hematopoietic stem cell transplant (RIC-HCT) are based on data derived mainly from large registry and single-centre retrospective studies. Thus, at the present time, there is limited direct evidence supporting the current practice in selecting patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) for RIC versus myeloablative conditioning (MAC) transplants. To determine the relationship between dose intensity of conditioning regimen and survival outcomes after allografting in AML/ALL patients, we performed a meta-analysis of 23 clinical trials reported between 1990 and 2013 involving 15,258 adult patients that compare survival outcomes after RIC-HCT versus MAC-HCT. RIC-HCT resulted in comparable <2-year and 2-6 year overall survival (OS) rates post-transplantation even though the RIC-HCT recipients were older and had more active disease than MAC-HCT recipients. The 2-6 year progression-free survival (PFS), nonrelapse mortality, acute graft-versus-host disease (GvHD) and chronic GvHD rates were reduced after RIC-HCT, but relapse rate was increased. Similar outcomes were observed regardless of disease type and status at transplantation. Odds ratio for all outcomes remained comparable with or without performing separate analyses for the year of HCT and for retrospective versus prospective studies. Among RIC-HCT recipients, survival rates were superior if patients were in CR at transplantation. Significant inter-study heterogeneity for aGvHD data and publication bias for PFS data were observed. This meta-analysis showed no OS benefit of MAC-HCT over RIC-HCT across the entire cohort of patients suggesting that RIC-HCT could be an effective therapeutic option for AML/ALL patients who are ineligible for MAC-HCT and CR status is preferred before RIC-HCT.

    Purpose TBI plays an important role in patients undergoing HCT, but is associated with significant toxicities. Targeted TBI using helical tomotherapy (HT) results in reduced doses to normal organs, which predict for reduced toxicities compared to standard TBI. Methods and Materials Thirteen patients with multiple myeloma (MM) were treated on an autologous tandem transplant Phase I trial with high dose melphalan, followed 6 weeks later by TMI to skeletal bone. Doses levels were 10, 12, 14, and 16 Gy at 2 Gy QD/BID. On a separate allogeneic HCT trial, 8 patients (5 AML, 1 ALL, 1 NHL, 1 MM) were treated with TMI+TLI + splenic RT to 12 Gy (1.5 Gy BID) combined with fludarabine/melphalan. Results For the 13 patients on the tandem autoHCT trial, median age was 54 (42–66). Median organ doses were 15–65% that of the GTV dose. Grade 1–2 acute toxicities were primarily observed. Six reported no vomiting, 9 no mucositis, 6 no fatigue, and 8 no diarrhea. For the 8 patients on the alloHCT trial, the median age was 52 (24–61). Grade 2–3 nausea, vomiting, mucositis and diarrhea were observed. On both trials no grade 4 non-hematologic toxicity was observed and all patients engrafted successfully. Conclusions This study demonstrates that TMI using HT is clinically feasible. Reduced acute toxicities observed compare favorably to those seen with standard TBI. Initial results are encouraging and warrant further evaluation as a method to dose escalate with acceptable toxicity or to offer TBI containing regimens to patients unable to tolerate standard approaches.

    The prognostic relevance of cytogenetics at diagnosis on the outcome of allogeneic hematopoietic stem cell transplantation (alloHCT) for adult acute lymphoblastic leukemia (ALL) remains unclear. We retrospectively analyzed outcomes of 333 adult ALL patients who underwent alloHCT at our institution over a 10-year period. Patients were classified according to disease status at transplantation (complete response [CR] 1 [n = 202] or > CR1) and according to cytogenetic risk, defined as good (2%), intermediate (42%), poor (46%), or unknown (10%) based on available outcome data for each of the cytogenetic abnormalities. Three-year overall survival (OS), leukemia-free survival (LFS), and relapse incidence (RI) were 55.7%, 47.9% and 27.5%, respectively; 1-year nonrelapse mortality (NRM) was 17.3%. For patients undergoing alloHCT in CR1, 3-year OS, LFS, and RI were 69.8%, 62.3%, and 17.1%, respectively. In multivariable analysis, cytogenetic risk did not impact OS or LFS for the whole cohort or for patients who underwent transplantation in CR1. Disease status at alloHCT was an independent predictor for LFS (CR1 versus others: hazard ratio [HR], 3.17; P < .01) and OS (CR1 versus others: HR, 2.90; P < .01). Graft-versus-host disease prophylaxis with tacrolimus/sirolimus was associated with a low NRM of 11.5% in the alloHCT recipients in CR1. Our data indicate that cytogenetic risk is not an independent predictor of outcomes in alloHCT performed to treat adult ALL. PMID:27044907

    Acute biphenotypic leukemias or mixed phenotype acute leukemias (MPAL) are rare and considered high risk. The optimal treatment and the role of allogeneic hematopoietic stem cell transplantation (alloHCT) are unclear. Most prior case series include only modest numbers of patients who underwent transplantation. We analyzed the outcome of 95 carefully characterized alloHCT patients with MPAL reported to the Center for International Blood and Marrow Transplant Research between 1996 and 2012. The median age was 20 years (range, 1 to 68). Among the 95 patients, 78 were in first complete remission (CR1) and 17 were in second complete remission (CR2). Three-year overall survival (OS) of 67% (95% confidence interval [CI], 57 to 76), leukemia-free survival of 56% (95% CI, 46 to 66), relapse incidence of 29% (95% CI, 20 to 38), and nonrelapse mortality of 15% (95% CI, 9 to 23) were encouraging. OS was best in younger patients (<20 years), but no significant differences were observed between those 20 to 40 years of age and those who were 40 years or older. A matched-pair analysis showed similar outcomes comparing MPAL cases to 375 acute myelogenous leukemia or 359 acute lymphoblastic leukemia cases. MPAL patients had more acute and a trend for more chronic graft-versus-host disease. No difference was observed between patients who underwent transplantation in CR1 versus those who underwent transplantation in CR2. AlloHCT is a promising treatment option for pediatric and adult patients with MPAL with encouraging long-term survival. PMID:26903380

    Purpose To investigate the prognostic value of the Hematopoietic Cell Transplantation–Specific Comorbidity Index (HCT-CI) in patients who received transplantation admitted to the intensive care unit (ICU). Patients and Methods We investigated the association of HCT-CI with inpatient mortality and overall survival (OS) among 377 patients who were admitted to the ICU within 100 days of allogeneic stem-cell transplantation (ASCT) at our institution. HCT-CI scores were collapsed into four groups and were evaluated in univariate and multivariate analyses using logistic regression and Cox proportional hazards models. Results The most common pretransplantation comorbidities were pulmonary and cardiac diseases, and respiratory failure was the primary reason for ICU admission. We observed a strong trend for higher inpatient mortality and shorter OS among patients with HCT-CI values ≥ 2 compared with patients with values of 0 to 1 in all patient subsets studied. Multivariate analysis showed that patients with HCT-CI values ≥ 2 had significantly higher inpatient mortality than patients with values of 0 to 1 and that HCT-CI values ≥ 4 were significantly associated with shorter OS compared with values of 0 to 1 (hazard ratio, 1.74; 95% CI, 1.23 to 2.47). The factors associated with lower inpatient mortality were ICU admission during the ASCT conditioning phase or the use of reduced-intensity conditioning regimens. The overall inpatient mortality rate was 64%, and the 1-year OS rate was 15%. Among patients with HCT-CI scores of 0 to 1, 2, 3, and ≥ 4, the 1-year OS rates were 22%, 17%, 18%, and 9%, respectively. Conclusion HCT-CI is a valuable predictor of mortality and survival in critically ill patients after ASCT. PMID:24127454

    Standard first-line therapy for older patients with high-risk MDS consists of hypomethylating agents such as azacitidine (AZA). However, the only approach with curative potential remains allogeneic hematopoietic cell transplantation (HCT). So far no direct comparison of both strategies has been carried out. The outcomes of two well balanced cohorts of high-risk MDS patients defined by age (60–70 years), performance status (ECOG ≤2) and donor availability (yes/no) were compared including 103 patients undergoing HCT and 75 patients without this option who received AZA. The estimated 2-year overall survival (OS) after the start of treatment was 39% (95% CI, 30% to 50%) for the HCT patients and 23% (95% CI, 14 to 40%) for the AZA patients. In a multivariate Cox regression analysis of all (n=178) patients ECOG score (0 vs. 1 vs. 2, HR: 2.9/3.9, p<0.001), cytogenetics (good vs. intermediate vs. poor, HR: 1.2/1.7, p=0.026) and type of treatment (HCT vs. AZA, HR: 0.3, p=0.007) were associated with OS. This retrospective cohort analysis suggests a survival advantage with allogeneic HCT compared to treatment with AZA in medically fit high-risk MDS patients 60 to 70 years of age, Prospective controlled studies are warranted.

    Allogeneic hematopoietic cell transplantation (allo-HCT) remains the only curative treatment option for myelofibrosis (MF) despite the emergence of novel targeted therapies. To reduce graft rejection and graft-versus-host disease (GvHD), current allo-HCT protocols often include in vivo T lymphocyte depletion using polyclonal anti-thymocyte globulin (ATG). Shortly after ATG administration, an immediate inflammatory response with fever, chills, and laboratory alterations such as cytopenias, elevation of serum C-reactive protein, bilirubin, and transaminases can develop. Here, we explore whether MF patients, who commonly exhibit extramedullary hematopoiesis in the liver, might be particularly susceptible to ATG-induced liver toxicity. To test this hypothesis, we analyzed 130 control and 94 MF patients from three transplant centers treated with or without ATG during the allo-HCT conditioning regimen. Indeed, hyperbilirubinemia was found in nearly every MF patient treated with ATG (MF-ATG 54/60 = 90 %) as compared to non-ATG treated MF (MF-noATG 15/34 = 44.1 %, p < 0.001) and respectively ATG-treated non-MF patients of the control group (control-ATG, 43/77 = 56 %, p < 0.001). In contrast, transaminases were only inconsistently elevated. Hyperbilirubinemia was in most cases self-limiting and not predictive of increased incidence of non-relapse mortality, hepatic sinusoidal obstruction syndrome (SOS) or liver GvHD. In sum, awareness of this stereotypic bilirubin elevation in MF patients treated with ATG provides a relatively benign explanation for hyperbilirubinemia occurring in these patients during the early transplant. However, attention to drug levels of biliary excreted drugs is warranted, since altered bile flow may influence their clearance and enhance toxicity (e.g., busulfan, antifungal agents).

    Cytomegalovirus (CMV) infection is still a major infectious complication after allogeneic hematopoietic cell transplantation (HCT). Recently, CMV reactivation was reported to be associated with a decreased risk of relapse in patients with acute myeloid leukemia (AML). We herein retrospectively evaluated the impact of early CMV reactivation on the incidence of disease relapse after allo-HCT using the database of the Transplant Registry Unified Management Program (TRUMP) at the JSHCT. Patients who underwent their first allo-HCT from HLA-matched related or unrelated donors between 2000 and 2009, and who survived without disease relapse until day 100 after transplantation, were analyzed. CMV reactivation was associated with a decreased cumulative incidence of relapse among patients with AML, but not in patients with other hematological malignancies in our study. However, this benefit was nullified by the increased rate of non-relapse mortality. The underlying mechanism is unclear, but the immunological reaction against CMV reactivation plays an essential role in this association. Thus, immune augmentation treatment options including vaccination and adoptive T-cell transfer might be useful for taking advantage of the efficacy of CMV reactivation while minimizing the increase in non-relapse mortality.

    The role of allogeneic hematopoietic cell transplantation (alloHCT) in HIV-positive patients is not known. Using the CIBMTR database, we retrospectively evaluated 23 HIV-positive patients undergoing matched sibling (n=19) or unrelated (n=4) donor transplants between 1987 and 2003. The median age at alloHCT was 32 years. Indications for alloHCT were diverse and included malignant (n=21) and non-malignant (n=2) hematologic disorders. Nine patients (39%) were transplanted after 1996, the approximate year highly active anti-retroviral therapy became standard. The median time to neutrophil engraftment was 16 days (range 7–30) and the cumulative incidences of grades II – IV acute graft-versus-host disease (GVHD) at 100 days, chronic GVHD and survival at 2 years were 30% (95% C.I. 14-50), 28% (95% C.I. 12-48) and 30% (95% C.I. 14-50), respectively. At a median follow-up of 59 months, 6 patients are alive. Survival appears better among the patients transplanted after 1996: 4 of 9 patients transplanted after 1996 survive compared to 2 of 14 patients transplanted prior to 1996. These data suggest that alloHCT is feasible for selected HIV-positive patients with malignant and non-malignant disorders. Prospective studies are needed in these patients to evaluate the safety and efficacy of this modality in specific diseases. PMID:19539219

    Allogeneic hematopoietic cell transplantation (HCT) is the only curative strategy for patients with myelodysplastic syndrome (MDS) and myeloproliferative disorders (MPD). We report the results of 148 patients (median age = 59 years old) with de novo MDS (n = 40), acute myelogenous leukemia (AML) after antecedent MDS/MPD (n = 49), treatment-related MDS (t-MDS) (n = 25), MPD (n = 27), and chronic myelomonocytic leukemia (CMML) (n = 7) who underwent allogeneic HCT using a conditioning regimen of low-dose total body irradiation (TBI) alone (200 cGy) on day 0 (n = 5) or with the addition of fludarabine (Flu) 30 mg/m(2)/day on days -4 to -2 (n = 143). Postgrafting immunosuppression consisted of cyclosporine and mycophenolate mofetil (MMF). Seventy-five patients (51%) received an allograft from a matched related donor (MRD), and 73 patients (49%) were recipients of unrelated donor (URD) grafts. There was no significant difference in the incidence of acute (gr II-IV) and chronic extensive graft-versus-host disease (aGVHD, cGVHD) between the recipients of related and unrelated donor grafts. By day +28, 75% of patients demonstrated mixed T cell chimerism. Graft rejection was seen in 15% of patients. With a median follow-up of 47 (range: 6-89) months, the 3-year relapse-free survival (RFS) and overall survival (OS) are both 27% for all patients, with a relapse incidence of 41%. The 3-year RFS for the patients with de novo MDS, AML after antecedent MDS/MPD, t-MDS, MPD, and CMML were 22%, 20%, 29%, 37%, and 43%, respectively, and the 3-year OS was 20%, 23%, 27%, 43%, and 43%, respectively. The 3-year nonrelapse mortality (NRM) was 32%. Factors associated with a lower risk of relapse were the development of extensive cGVHD and having a low risk or intermediate-1 risk International Prognostic Score for the de novo MDS patients.

    The impact of Janus kinase (JAK) 1/2 inhibitor therapy before allogeneic hematopoietic cell transplantation (HCT) has not been studied in a large cohort in myelofibrosis (MF). In this retrospective multicenter study, we analyzed outcomes of patients who underwent HCT for MF with prior exposure to JAK1/2 inhibitors. One hundred consecutive patients from participating centers were analyzed, and based on clinical status and response to JAK1/2 inhibitors at the time of HCT, patients were stratified into 5 groups: (1) clinical improvement (n = 23), (2) stable disease (n = 31), (3) new cytopenia/increasing blasts/intolerance (n = 15), (4) progressive disease: splenomegaly (n = 18), and (5) progressive disease: leukemic transformation (LT) (n = 13). Overall survival (OS) at 2 years was 61% (95% confidence interval [CI], 49% to 71%). OS was 91% (95% CI, 69% to 98%) for those who experienced clinical improvement and 32% (95% CI, 8% to 59%) for those who developed LT on JAK1/2 inhibitors. In multivariable analysis, response to JAK1/2 inhibitors (P = .03), dynamic international prognostic scoring system score (P = .003), and donor type (P = .006) were independent predictors of survival. Among the 66 patients who remained on JAK1/2 inhibitors until stopped for HCT, 2 patients developed serious adverse events necessitating delay of HCT and another 8 patients had symptoms with lesser severity. Adverse events were more common in patients who started tapering or abruptly stopped their regular dose ≥6 days before conditioning therapy. We conclude that prior exposure to JAK1/2 inhibitors did not adversely affect post-transplantation outcomes. Our data suggest that JAK1/2 inhibitors should be continued near to the start of conditioning therapy. The favorable outcomes of patients who experienced clinical improvement with JAK1/2 inhibitor therapy before HCT were particularly encouraging, and need further prospective validation. PMID:26493563

    The use of allogeneic hematopoietic cell transplantation (HCT) has expanded progressively, facilitated by the increasing availability of unrelated donors and cord blood, and the inclusion of older patients as transplantation candidates. Indications remain diagnosis-dependent. As novel nontransplantation modalities have been developed concurrently, many patients come to HCT only when no longer responding to such therapy. However, patients with refractory or advanced disease frequently relapse after HCT, even with high-dose conditioning, and more so with reduced-intensity regimens as used for patients of older age or with comorbid conditions. Thus, patients with high-risk malignancies who have substantial comorbidities or are of advanced age are at high risk of both relapse and nonrelapse mortality and should probably not be transplanted. Being in remission or at least having shown responsiveness to pre-HCT therapy is generally associated with increased transplantation success. In addition, to handle the stress associated with HCT, patients need a good social support system and a secure financial net. They must be well informed, not only about the transplantation process, but also about expected or potential post-HCT events, including graft-versus-host disease and delayed effects that may become manifest only years after HCT.

    Purpose We reported encouraging early results of allogeneic hematopoietic cell transplantation (HCT) after nonmyeloablative conditioning in 64 patients who had advanced chronic lymphocytic leukemia (CLL). Here, we have extended the follow-up to a median of 5 years and have included data on an additional 18 patients. Patients and Methods Eighty-two patients, age 42 to 72 years, who had fludarabine-refractory CLL were conditioned with 2 Gy total-body irradiation alone or combined with fludarabine followed by HCT from related (n = 52) or unrelated (n = 30) donors. Results Complete remission (CR) and partial remission were achieved in 55% and 15% of patients, respectively. Higher CR rates were noted after unrelated HCT (67% v 48%). The 5-year incidences of nonrelapse mortality (NRM), progression/relapse, overall survival, and progression-free survival were 23%, 38%, 50%, and 39%, respectively. Among 25 patients initially reported in CR, 8% relapsed and 8% died as a result of NRM, whereas 84% have remained alive and in CR. Among 14 responding patients who were tested and who had molecular eradication of their disease, two died as a result of NRM, two relapsed, and 10 have remained negative. At 5 years, 76% of living patients were entirely well, whereas 24% continued to receive immunosuppression for chronic graft-versus-host disease; the median performance status in each group was 100% and 90%, respectively. Lymphadenopathy ≥ 5 cm, but not cytogenetic abnormalities at HCT, predicted relapse. In a risk-stratification model, patients who had lymphadenopathy less than 5 cm and no comorbidities had a 5-year OS of 71%. Conclusion Nonmyeloablative HCT resulted in a median survival of 5 years for patients who had fludarabine-refractory CLL with sustained remissions and in the continued resolution of chronic graft-versus-host disease in surviving patients.

    The poor survival rates of refractory/relapsed acute myeloid leukemia (AML) patients after haematopoietic cell transplantation (HCT) requires the development of additional immune therapeutic strategies. As the elicitation of tumor-antigen specific cytotoxic T lymphocytes (CTLs) is associated with reduced relapses and enhanced survival, enhanced priming of these CTLs using an anti-AML vaccine may result in long-term immunity against AML. Cord blood (CB), as allogeneic HCT source, may provide a unique setting for such post-HCT vaccination, considering its enhanced graft-versus-leukemia (GvL) effects and population of highly responsive naïve T cells. It is our goal to develop a powerful and safe immune therapeutic strategy composed of CB-HCT followed by vaccination with CB CD34+-derived dendritic cells (DCs) presenting the oncoprotein Wilms Tumor-1 (WT1), which is expressed in AML-blasts in the majority of patients. Here, we describe the optimization of a clinically applicable DC culture protocol. This two-step protocol consisting of an expansion phase followed by the differentiation toward DCs, enables us to generate sufficient cord blood-derived DCs (CBDCs) in the clinical setting. At the end of the culture, the CBDCs exhibit a mature surface phenotype, are able to migrate, express tumor antigen (WT1) after electroporation with mRNA encoding the full-length WT1 protein, and stimulate WT1-specific T cells.

    Allogeneic hematopoietic cell transplantation (allo HCT) is the only curative therapy for the myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN), but treatment toxicity has been a barrier to its more widespread use. The nonmyeloablative regimen of total lymphoid irradiation (TLI) and antithymocyte globulin (ATG) permits the establishment of donor hematopoiesis necessary for the graft-versus-malignancy effect and is protective against acute graft-versus-host disease (aGVHD), but it has minimal direct cytotoxicity against myeloid diseases. We explored the use of TLI-ATG conditioning to treat 61 patients with allo HCT for MDS (n = 32), therapy-related myeloid neoplasms (n = 15), MPN (n = 9), and chronic myelomonocytic leukemia (n = 5). The median age of all patients was 63 years (range, 50 to 73). The cumulative incidence of aGVHD grades II to IV was 14% (95% confidence interval [CI], 4% to 23%) and for grades III to IV, 4% (95% CI, 0 to 9%), and it did not differ between patients who received allografts from related or unrelated donors. The cumulative incidence of nonrelapse mortality (NRM) at 100 days, 12 months, and 36 months was 0%, 7%, and 11%. Overall survival and progression-free survival were 41% (95% CI, 29% to 53%) and 35% (95% CI, 23% to 48%), respectively. The safety and tolerability of TLI-ATG, as exemplified by its low NRM, provides a foundation for further risk-adapted or prophylactic interventions to prevent disease progression. PMID:24607552

    We compared outcomes of 916 diffuse large B cell lymphoma (DLBCL) patients aged >or=18 years undergoing first autologous (n = 837) or myeloablative (MA) allogeneic hematopoietic cell transplant (HCT) (n = 79) between 1995 and 2003 reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). Median follow-up was 81 months for allogeneic HCT versus 60 months for autologous HCT. Allogeneic HCT recipients were more likely to have high-risk disease features including higher stage, more prior chemotherapy regimens, and resistant disease. Allogeneic HCT was associated with a higher 1 year treatment-related mortality (TRM) (relative risk [RR] 4.88, 95% confidence interval [CI], 3.21-7.40, P < .001), treatment failure (RR 2.06, 95% CI, 1.54-2.75, P < .001), and mortality (RR 2.75, 95% CI, 2.03-3.72, P < .001). Risk of disease progression was similar in the 2 groups (RR 1.12, 95% CI, 0.73-1.72, P = .59). In fact, for 1-year survivors, no significant differences were observed for TRM, progression, progression-free (PFS) or overall survival (OS). Increased risks of TRM and mortality were associated with older age (>50 years), lower performance score, chemoresistance, and earlier year of transplant. In a cohort of mainly high-risk DLBCL patients, upfront MA allogeneic HCT, although associated with increased early mortality, was associated with a similar risk of disease progression compared to lower risk patients receiving autologous HCT.

    Cytomegalovirus (CMV) reactivation after allogeneic hematopoietic cell transplant (allo-HCT) has been associated with reduced risk of relapse in patients with acute myeloid leukemia (AML). However the influence of the conditioning regimen on this protective effect of CMV reactivation after allo-HCT is relatively unexplored. To address this, we evaluated the risk of relapse in 264 AML patients who received T cell replete, 6/6 HLA matched sibling or 10/10 HLA matched unrelated donor transplantation at a single institution between 2006 and 2011. Out of these 264 patients, 206 received myeloablative (MA) and 58 received reduced intensity conditioning (RIC) regimens. CMV reactivation was observed in 88 patients with MA conditioning and 37 patients with RIC. At a median follow up of 299 days, CMV reactivation was associated with significantly lower risk of relapse in patients who received MA conditioning both in univariate (P= .01) and multivariate analyses (hazard ratio of 0.5246, P= .006), however CMV reactivation did not significantly affect the risk of relapse in our RIC cohort. These results confirm the protective effect of CMV reactivation on relapse in AML patients after allo-HCT reported by previous studies, however they suggest that this protective effect of CMV reactivation on relapse is influenced by the conditioning regimen used with the transplant.

    Limited data exist regarding health care utilization (HCU) in patients receiving allogeneic hematopoietic cell transplantation (alloHCT) for sickle cell disease. Financial data from 2002 to 2011 were analyzed for 26 alloHCT patients and 48 control subjects (referred but without alloHCT). HCU of alloHCT was determined over 3 time periods: pre-alloHCT, during alloHCT (day 0 to day +365), and post-alloHCT. The median total cost per patient during the alloHCT year was $413,000 inpatient and $18,000 outpatient. Post-alloHCT HCU decreased when compared with pre-alloHCT and control subjects. The median cost of post-alloHCT outpatient visits per patient was significantly less when compared with pre-alloHCT (P = .044). The median cost of post-alloHCT inpatient visits per patient approached significance when compared with those pre-alloHCT (P = .079). Sixteen post-alloHCT patients, 19 control subjects, and 14 unaffected siblings were surveyed using Pediatric Quality of Life Inventory and EuroQOL questionnaires; however, the questionnaire scores across all 3 patient groups were not statistically significant (P = .2638). When adjusted for health-related quality of life, the analysis suggested alloHCT has a positive impact on health-related quality of life over control subjects. These pilot data support our hypothesis that alloHCT in children with sickle cell disease reduces HCU compared with control subjects without alloHCT. PMID:25615608

    The introduction of reduced-intensity conditioning (RIC) regimens made it possible to offer allogeneic hematopoietic cell transplantation (alloHCT) to older patients with myelodysplastic syndromes (MDS). However, the relative risks and benefits of alloHCT compared with novel nontransplant therapies continue to be the source of considerable uncertainty. We will perform a prospective biologic assignment trial to compare RIC alloHCT with nontransplant therapies based on donor availability. Primary outcome is 3-year overall survival. Secondary outcomes include leukemia-free survival, quality of life, and cost-effectiveness. Four hundred patients will be enrolled over roughly 3 years. Planned subgroup analyses will evaluate key biologic questions, such as the impact of age and response to hypomethylating agents on treatment effects. Findings from this study potentially may set a new standard of care for older MDS patients who are considered candidates for alloHCT. PMID:24972249

    Recent studies comparing allogeneic hematopoietic cell transplantation (HCT) using HLA-matched unrelated donors (MUD) versus HLA-haploidentical donors in patients with acute myeloid leukemia (AML) have suggested equivalent outcomes. The graft source used in most studies of haploidentical transplants has been bone marrow. Similar comparisons between MUD and haplo-HCT using peripheral blood as a graft source have not been adequately performed. We reviewed the records of all 52 AML patients who underwent haplo-HCT (using peripheral blood and post-transplantation high-dose cyclophosphamide) between January 2010 and August 2015 at our institution and compared their outcomes with 88 patients who had a MUD transplant in the same time frame and were frequency matched (preanalysis) to the haploidentical group for conditioning intensity. Multivariate analysis found no difference in outcomes between the 2 groups with the exception of slower count recovery after haploidentical allografts (HR, .48; 95% CI, .32 to .74 for platelets, and HR, .47; 95% CI, .32 to .71 for neutrophils; P < .001 for both comparisons). Our retrospective analysis, although limited by the small sample size, suggests largely similar outcomes with peripheral blood haploidentical versus MUD transplants for AML. PMID:27223108

    Risks of secondary solid cancers among allogeneic hematopoietic cell transplant (HCT) recipients who receive conditioning without total body irradiation are not well known. We evaluated the incidence and risk factors for solid cancers after HCT using high-dose busulfan-cyclophosphamide conditioning in 4318 recipients of first allogeneic HCT for acute myeloid leukemia in first complete remission (N = 1742) and chronic myeloid leukemia in first chronic phase (N = 2576). Our cohort represented 22 041 person-years at risk. Sixty-six solid cancers were reported at a median of 6 years after HCT. The cumulative-incidence of solid cancers at 5 and 10 years after HCT was 0.6% and 1.2% among acute myeloid leukemia and 0.9% and 2.4% among chronic myeloid leukemia patients. In comparison to general population incidence rates, HCT recipients had 1.4× higher than expected rate of invasive solid cancers (95% confidence interval, 1.08-1.79, P = .01). Significantly elevated risks were observed for tumors of the oral cavity, esophagus, lung, soft tissue, and brain. Chronic graft-versus-host disease was an independent risk factor for all solid cancers, and especially cancers of the oral cavity. Recipients of allogeneic HCT using busulfan-cyclophosphamide conditioning are at risk for developing solid cancers. Their incidence continues to increase with time, and lifelong cancer surveillance is warranted in this population. PMID:20926773

    Busulfan is a commonly used chemotherapeutic agent in myeloablative conditioning regimens for allogeneic hematopoietic cell transplantation (allo-HCT). It has been associated with sinusoidal-obstructive syndrome(SOS) as a life-threatening complication of myeloablative allo-HCT, yet it has not been found to cause severe hepatocellular injury, even in cases of significant accidental overdose.We report the case of a 31-year-old male with a history of high-risk myelodysplastic syndrome transitioning to acute myeloid leukemia, who in complete remission underwent allo-HCT using myeloablative busulfan–fludarabine conditioning, and who developed hepatic failure. While he met clinical criteria for SOS and was treated with defibrotide,liver biopsy demonstrated severe subacute hepatic necrosis and lacked characteristics of SOS. Further evaluation revealed that the patient was homozygous for the HFE H63D gene mutation, associated with hereditary hemochromatosis.Both Busulfan and iron overload related to HFE H63D homozygosity can cause oxidative stress resulting in cellular injury, and the cumulative effects of these risk factors are possibly responsible for the severe hepatocellular injury in this case, making our patient the first-known case of subacute hepatic necrosis related to busulfan administration.

    Although allogeneic hematopoietic cell transplantation (HCT) is an expensive treatment for hematological disorders, little is known about the financial consequences for the patients who undergo this procedure. We analyzed factors associated with its financial burden and its impact on health behaviors of allogeneic HCT recipients. A questionnaire was retrospectively mailed to 482 patients who underwent allogeneic HCT from January 2006 to June 2012 at the Mayo Clinic, to collect information regarding current financial concerns, household income, employment, insurance, out-of-pocket expenses, and health and functional status. A multivariable logistic regression analysis identified factors associated with financial burden and treatment nonadherence. Of the 268 respondents (56% response rate), 73% reported that their sickness had hurt them financially. All patients for whom the insurance information was available (missing, n = 13) were insured. Forty-seven percent of respondents experienced financial burden, such as household income decreased by >50%, selling/mortgaging home, or withdrawing money from retirement accounts. Three percent declared bankruptcy. Younger age and poor current mental and physical functioning increased the likelihood of financial burden. Thirty-five percent of patients reported deleterious health behaviors because of financial constraints. These patients were likely to be younger, have lower education, and with a longer time since HCT. Being employed decreased the likelihood of experiencing financial burden and treatment nonadherence due to concern about costs. A significant proportion of allogeneic HCT survivors experience financial hardship despite insurance coverage. Future research should investigate potential interventions to help at-risk patients and prevent adverse financial outcomes after this life-saving procedure. PMID:24867778

    Epidermolysis bullosa (EB) is a rare genetic disease that is known for continuous skin blistering caused by minor trauma. The skin blisters and bullae that develop often cause skin defects. There is no definitive treatment for EB, only symptomatic relief. We report our experience with cultured allogenic keratinocyte grafting in a newborn patient with EB simplex who had unhealed raw surfaces and was not a skin grafting candidate. The skin lesions of the patient were covered with cultured allogenic keratinocyte grafts and re-epithelialized quickly with no scarring. Allogenic keratinocyte grafting reduced pain and produced noticeable improvements in the unhealed wounds. We think that allogenic keratinocyte grafting can play an important role in the management of patients with EB simplex. PMID:22346287

    Despite a wide spectrum of treatment options, mantle cell lymphoma (MCL) remains a challenging hematologic malignancy to manage. Advances in front-line therapy, including the monoclonal antibody rituximab and increasing use of cytarabine, have improved remission rates. Autologous hematopoietic cell transplantation (HCT) can effectively consolidate remission of MCL, leading to encouraging survival beyond 5 yr. However, nearly all patients with MCL will relapse and require salvage therapy. Novel agents such as ibrutinib, bortezomib, and lenalidomide have dramatically expanded the options for treating relapsed MCL. In this review, we summarize the clinical evidence supporting the use of allogeneic donor HCT in MCL and make recommendations on indications for its use. Data suggest that allogeneic donor HCT is the only curative therapy for patients with poor prognosis or aggressive MCL. Patient selection, timing, and optimal use remain a matter of scientific debate and given the rapidly changing therapeutic landscape of MCL, the outcomes of allogeneic HCT should be interpreted in the context of novel therapeutics.

    Consensus guidelines recommend various screening examinations for survivors after allogeneic hematopoietic cell transplantation (HCT), but how often these examinations detect abnormal findings is unknown. We reviewed the medical records of 118 patients who received comprehensive, standardized evaluations at 1 year after allogeneic HCT at Fred Hutchinson Cancer Research Center/Seattle Cancer Care Alliance. Abnormal findings were common, including moderate to severe pulmonary dysfunction (16%), fasting hyperlipidemia (56%), osteopenia (52%), osteoporosis (6%), and active chronic graft-versus-host disease (cGVHD) (64%). Recurrent malignancy (4%) and cGVHD (29%) were detected in previously unsuspected cases. Only 3% of patients had no abnormal findings. We conclude that comprehensive evaluation at 1 year after allogeneic HCT detects a high prevalence of medical problems. Longer follow-up is needed to determine whether early detection and intervention affect later morbidity and mortality. PMID:19285628

    Normal karyotype acute myeloid leukemia (NK-AML) with CCAAT/enhancer binding protein α (CEBPA) mutations is known to have a more favorable prognosis. However, direct comparison of the clinical significance according to consolidation therapy has not been widely performed in patients with NK-AML. A total of 404 patients with NK-AML who received intensive induction chemotherapy were included in the present study. Diagnostic samples from the patients were evaluated for CEBPA mutations by direct sequencing. CEBPA single (sm) or double mutation (dm) was observed in 27 (6.7 %) and 51 (12.6 %) patients, respectively. CEBPA (dm) was associated with GATA2 (mut), and it was less frequently associated with FLT3-ITD(pos), NPM1 (mut), and DNMT3A (mut) in comparison with CEBPA (wild) or CEBPA (sm) (all p values <0.05). On multivariate analysis, CEBPA (dm) (p = 0.007, OR 39.593) was an independent risk factor for achievement of complete remission (CR). With a median follow-up of 40.1 months, CEBPA (dm) showed a favorable overall survival (OS), event-free survival (EFS), and lower relapse incidence (RI) in comparison with CEBPA (wild) (all p values <0.005). Comparison of clinical outcome analyses (consolidation chemotherapy vs. allogeneic hematopoietic cell transplantation (HCT)) demonstrated the role of consolidation treatment in patients with CEBPA (dm). Allogeneic HCT was associated with lower EFS and RI and a trend of higher non-relapse mortality. However, there was no statistically significant difference in OS. In conclusion, CEBPA (dm) was associated with other molecular mutations. Consolidation chemotherapy alone may overcome higher relapse rates by reducing the treatment mortality and increasing survival after relapse events in patients with CEBPA (dm) in NK-AML.

    Although typically found in cancers, frameshift mutations in microsatellites have also been detected in chronically inflamed tissues. Allogeneic hematopoietic cell transplantation (HCT) may potentially produce chronic tissue stress through graft-versus-host reactions. We examined non-neoplastic epithelial tissues (colon, buccal) obtained 1 to 5061 days after human allogeneic HCT for the presence of genomic alterations at 3 tetranucleotide and 3 mononucleotide microsatellite loci. Novel bands indicative of microsatellite instability (MSI) at tetranucleotide repeats were detected in laser-microdissected colonic crypts and in buccal smears of 75% and 42% of patients who received an allograft, respectively. In contrast, no MSI was found in similar tissues from control subjects and from patients after intensive chemotherapy or in buccal cells from patients after autologous HCT. The MSI found in colon, which was often affected by graft-versus-host disease, was not due to loss of expression or nitrosylation of DNA repair proteins. MSI in clinically intact oral mucosa was more frequently found at later time points after HCT. MSI was also found in 3 posttransplant squamous cell cancers examined. Our data show that genomic alterations in epithelium regularly occur after allogeneic HCT and may be implicated in the evolution of posttransplantation diseases, including secondary cancer.

    Grade 3 follicular lymphoma (FL) has aggressive clinical behavior. To evaluate the optimal first transplantation approach in relapsed/refractory grade 3 FL patients, we compared the long-term outcomes after allogeneic (allo-) vs autologous hematopoietic cell transplantation (auto-HCT) in the rituximab era. A total of 197 patients undergoing first reduced-intensity conditioning (RIC) allo-HCT or first auto-HCT during 2000-2012 were included. Rituximab-naive patients were excluded. Allo-HCT recipients were younger, more heavily pretreated and had a longer interval between diagnosis and HCT. The 5-year probabilities of non-relapse mortality (NRM), relapse/progression, PFS and overall survival (OS) for auto-HCT vs allo-HCT groups were 4% vs 27% (P<0.001), 61% vs 20% (P<0.001), 36% vs 51% (P=0.07) and 59% vs 54% (P=0.7), respectively. On multivariate analysis, auto-HCT was associated with reduced risk of NRM (relative risk (RR)=0.20; P=0.001). Within the first 11 months post HCT, auto- and allo-HCT had similar risks of relapse/progression and PFS. Beyond 11 months, auto-HCT was associated with higher risk of relapse/progression (RR=21.3; P=0.003) and inferior PFS (RR=3.2; P=0.005). In the first 24 months post HCT, auto-HCT was associated with improved OS (RR=0.42; P=0.005), but in long-time survivors (beyond 24 months) it was associated with inferior OS (RR=3.6; P=0.04). RIC allo-HCT as the first transplant approach can provide improved PFS and OS, in long-term survivors. PMID:26437062

    Grade-3 follicular lymphoma (FL) has aggressive clinical behavior. To evaluate the optimal first transplantation approach in relapsed/refractory grade-3 FL patients, we compared the long-term outcomes after allogeneic (allo-) vs. autologous hematopoietic cell transplantation (auto-HCT) in the rituximab-era. A total of 197 patients undergoing first RIC allo-HCT or first auto-HCT during 2000-2012 were included. Rituximab-naïve patients were excluded. Allo-HCT recipients were younger; more heavily pretreated, and had a longer interval between diagnosis and HCT. The 5-year probabilities of non-relapse mortality (NRM), relapse/progression, progression-free survival (PFS) and overall survival (OS) for auto-HCT vs. allo-HCT groups were 4% vs. 27% (p<0.001); 61% vs. 20% (p<0.001); 36% vs. 51% (p=0.07) and 59% vs. 54% (p=0.7), respectively. On multivariate analysis auto-HCT was associated with reduced risk of NRM (RR=0.20; p=0.001). Within the first 11months post-HCT auto- and allo-HCT had similar risks of relapse/progression and PFS. Beyond 11months, auto-HCT was associated with higher risk of relapse/progression (RR=21.3; p=0.003) and inferior PFS (RR=3.2; p=0.005). In the first 24 months post-HCT, auto-HCT was associated with improved OS (RR=0.42; p=0.005), but in long-time survivors (beyond 24 months) it was associated with inferior OS (RR=3.6; p=0.04). RIC allo-HCT as the first transplant approach can provide improved PFS and OS, in long-term survivors. PMID:26437062

  9. Analysis of the efficiency and costs of antifungal prophylaxis and mycological diagnostics in patients undergoing allogeneic haematopoietic cell transplantation: "real life" evaluation.

    Antifungal prophylaxis/therapy (AP/AT) raises the cost of allogeneic haematopoietic cell transplantation (alloHCT). Its efficacy, different approaches for AP/AT, diagnostic measures and cost-effectiveness must still be evaluated. In 2010, we conducted a prospective study with 106 consecutive patients receiving an alloHCT analysing AP/AT, choice and costs of diagnostics applied including CT scans, galactomannan (Gal) and β-D-glucan (β-D) testing. Antifungal prophylaxis in 91 patients consisted of fluconazole (FLU) or L-AMB (AmBisome™ 1 or 3 mg/kg/day b.w.), and antifungal therapy had to be initiated in 38 % of the FLU/L-AMB-1-mg patients but in none with L-AMB 3 mg. Empirical AT consisted of L-AMB 1 mg/kg (n = 12) and preemptive AT of L-AMB 3 mg/kg (n = 17) and proved very efficacious with no further antifungal drug escalation in 89.6 %. Mean costs of diagnostic measures were 402 €/alloHCT; however, only 22 % of the CT scans, 4 % of β-D and 3 % of galactomannan testing were positive. We detected one proven, 17 probable and 14 possible fungal infections. Due to the German diagnosis-related group system with additional compensation, all our AP/AT strategies were adequately reimbursed. While clinical symptoms and CT scans are the most commonly used, inexpensive decision-making tools for starting AT, the expensive laboratory diagnostic procedures are ineffective; we have therefore discontinued regular GAL/β-D testing and changed our AP in patients at risk.

    Abstract The purpose of this study is to explore the risk factors affecting the postoperative transfusion of allogeneic blood in patients undergoing orthopedics surgery with intraoperative blood salvage (IBS). A retrospective study of 279 patients undergoing orthopedic surgeries with IBS from May 2013 to May 2015 was enrolled. The binary logistic regression was used to find out the risk factors associated with postoperative transfusion of allogeneic blood in orthopedics patients with IBS, and then receiver operating characteristic (ROC) curve was drawn to determine the optimal threshold of the regression model. Single factor analysis showed that age, American Society of Anesthesiologists (ASA) grade, preoperative hemoglobin, operation time, received autologous blood, the laying time of autologous blood, bleeding volume, and postoperative drainage volume had significant effects on postoperative allogeneic blood transfusion. In binary logistic regression analysis, the independent factors predicting orthopedic patients with IBS need to transfuse allogeneic blood after surgeries were age (odds ratio [OR] = 0.415, P = 0.006), ASA grade (OR = 2.393, P = 0.035), preoperative hemoglobin (OR = 0.532, P = 0.022), and postoperative drainage volume (OR = 4.279, P = 0.000). The area under ROC curve was 0.79 and the predicted accuracy rate of the model was 81.58%. After operation, the orthopedic patients with IBS still have a high allogeneic blood transfusion rate, and IBS is not a perfect blood protection method. The logistic regression model of our study provides a reliable prediction for postoperative transfusion of allogeneic blood in orthopedic patients with IBS, which have a certain reference value.

    Engraftment syndrome (ES), characterized by fever, rash, pulmonary edema, weight gain, liver and renal dysfunction, and/or encephalopathy, occurs at the time of neutrophil recovery after hematopoietic cell transplantation (HCT). In this study, we evaluated the incidence, clinical features, risk factors, and outcomes of ES in children and adults undergoing first-time allogeneic HCT. Among 927 patients, 119 (13%) developed ES at a median of 10 days (interquartile range 9 to 12) after HCT. ES patients experienced significantly higher cumulative incidence of grade 2 to 4 acute GVHD at day 100 (75% versus 34%, P < .001) and higher nonrelapse mortality at 2 years (38% versus 19%, P < .001) compared with non-ES patients, resulting in lower overall survival at 2 years (38% versus 54%, P < .001). There was no significant difference in relapse at 2 years (26% versus 31%, P = .772). Suppression of tumorigenicity 2, interleukin 2 receptor alpha, and tumor necrosis factor receptor 1 plasma biomarker levels were significantly elevated in ES patients. Our results illustrate the clinical significance and prognostic impact of ES on allogeneic HCT outcomes. Despite early recognition of the syndrome and prompt institution of corticosteroid therapy, outcomes in ES patients were uniformly poor. This study suggests the need for a prospective approach of collecting clinical features combined with correlative laboratory analyses to better characterize ES. PMID:24892262

    This review discusses the use of prognostic factors, patient and donor selection, choice of conditioning regimens, and timing of transplant. It also describes the management of Philadelphia-positive acute lymphocytic leukemia (ALL) and central nervous system disease. All aggressively treated adults with ALL should be considered for allogeneic transplantation and tissue typed at diagnosis. We further suggest that eligible patients be entered into clinical trials (that incorporate transplantation); these unselected prospective outcome data are essential to evaluate the true value of allogeneic transplantation in adults with ALL.

    Patient-reported outcomes (PROs), including symptoms and health-related quality of life (HRQOL), provide a patient-centered description of hematopoietic cell transplantation (HCT)-related toxicity. These data characterize the patient experience after HCT and may have prognostic usefulness for long-term outcomes after HCT. We conducted a study of 32 patients after HCT (10 autologous HCT recipients, 11 full-intensity conditioning allogeneic HCT recipients, and 11 reduced-intensity conditioning allogeneic HCT recipients) to determine the feasibility of weekly electronic PRO collection from HCT until day (D) + 100. We used questions from the PRO version of the Common Terminology Criteria for Adverse Events to capture symptoms, and the Patient-Reported Outcomes Measurement Information System Global Health scale to measure physical and mental HRQOL. The vast majority (94%) of patients used the electronic PRO system, with only 6% opting for paper-and-pencil only. The median weekly percentage of participants who completed the surveys was 100% in all cohorts through hospital discharge, and remained 100% for the autologous HCT and reduced-intensity allogeneic HCT cohorts through D+100. Patients were satisfied with the electronic system, giving high marks for readability, comfort, and questionnaire length. Symptom severity varied by absolute level and type of symptom across the 3 cohorts, with the full-intensity allogeneic HCT cohort exhibiting the greatest median overall symptom severity, peaking at D+7. Median physical health HRQOL scores decreased with time in the 3 cohorts, and HRQOL was generally correlated with overall symptom severity. Our results demonstrate the feasibility of frequent electronic PROs in the early post-HCT period. Future studies in larger populations to explore predictive models using frequent PRO data for outcomes, including long-term HRQOL and survival, are warranted. PMID:23253558

    PURPOSE To identify favored choice of transplantation in patients with acute promyelocytic leukemia in second complete remission. PATIENTS We studied 294 acute promyelocytic leukemia (APL) patients receiving allogeneic (n=232) or autologous (62) hematopoietic cell transplantation (HCT) in second complete remission (CR2) reported to the Center for International Blood and Marrow Transplantation Research (CIBMTR) from 1995 to 2006 including pre-HCT PML/RAR∝ status in 155 (49% of allogeneic and 66% of autologous). METHODS Patient characteristics and transplant characteristics including treatment related mortality, overall survival, and disease free survival were collected and analyzed for both univariate and multivariate outcomes. RESULTS With median follow-up of 115 (allogeneic) and 72 months (autologous), 5-year disease-free survival (DFS) favored autologous 63% (49-75%) compared to allogeneic 50% (44-57%) (p=0.10) and overall survival (OS) 75% (63-85%) vs. 54% (48-61%) (p=.002) Multivariate analysis showed significantly worse DFS after allogeneic HCT (HR=1.88, 95% CI=1.16-3.06, p=0.011) and age >40 years (HR=2.30, 95% CI 1.44-3.67, p=0.0005). OS was significantly worse after allogeneic HCT (HR=2.66, 95%CI 1.52-4.65, p=0.0006; age >40 (HR=3.29, 95% CI 1.95-5.54, p<0.001) and CR1<12 months (HR=1.56 95% CI 1.07-2.26, p=0.021). Positive pre-HCT PML-RAR∝ status in 17/114 allogeneic and 6/41 autologous transplants did not influence relapse, treatment failure or survival in either group. The survival advantage for autografting was attributable to increased 3 years TRM: allogeneic 30%; autologous 2%, and GVHD. CONCLUSION We conclude that autologous HCT yields superior overall survival for APL in CR2. Long term DFS in autologous recipients, even with MRD+ grafts remains an important subject for further study. PMID:24691221

    This study assessed the incidence of long-term oral complications in 88 survivors of allogeneic haematopoietic cell transplantation (HCT). Patients examined were between 6 months and 6 years post-HCT and aged from 19 to 65 years. Subjects were investigated for both the subjective and objective features of long-term adverse oral effects of HCT. The most common oral symptoms reported were xerostomia (44%, n=39) and reduction in taste (20%, n=18). Only a minority of patients (15%) reported that oral disease had a significant adverse impact upon their quality of life. The majority of patients (53%) had clinical markers of oral chronic GVHD (cGVHD). The most frequently identified feature was salivary hypofunction, with 34% of subjects demonstrating a reduction in stimulated saliva. Oral mucosal changes consistent with cGVHD affected 21% of subjects. Oral cGVHD commonly occurs after allogeneic HCT, often coexists with cutaneous, hepatic or ocular cGVHD and may lead to debilitating symptoms. Transplant type and pre-existing acute GVHD are the major risk factors for oral cGVHD. The identification of risk factors specific for oral cGVHD may allow clinicians some foresight into identifying patients at high risk of developing oral cGVHD and encourage attention to education, regular oral surveillance and rigorous preventative oral health strategies both pre- and post-transplant.

    The incidence of excessive adiposity is increasing worldwide and is associated with numerous adverse health outcomes. We compared outcomes by body mass index (BMI) for adult patients with acute myeloid leukemia (AML) who underwent autologous (auto, n=373), related donor (RD, n=2041), or unrelated donor (URD, n=1801) allogeneic myeloablative hematopoietic cell transplantation (HCT) using marrow or peripheral blood stem cells reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) from 1995-2004. Four weight groups by BMI (kg/m2) were defined: underweight < 18; normal 18 – 25; overweight >25 – 30; and obese > 30. Multivariable analysis referenced to the normal weight group showed an increased risk of death for underweight patients in the RD group (RR, 1.92; 95% CI, 1.28-2.89; P = 0.002) but not in the URD group. There were no other differences in outcomes among the other weight groups within the other HCT groups. Overweight and obese patients enjoyed a modest decrease in relapse incidence, though this did not translate into a survival benefit. Small numbers of patients limit the ability to better characterize the adverse outcomes seen in the underweight RD but not the underweight URD allogeneic HCT patients. Obesity alone should not be considered a barrier to HCT. PMID:20412867

    Purpose Allogeneic hematopoietic cell transplantation (HCT) is curative therapy for chronic myeloid leukemia (CML), but its long-term outcomes are not well described. We studied the long-term outcomes of CML patients in first chronic phase who receive an allogeneic HCT. Patients and Methods Our study included 2,444 patients who received myeloablative HCT for CML in first chronic phase between 1978 and 1998 and survived in continuous complete remission for at least 5 years (median follow-up, 11 years; range, 5 to 25 years). Donor sources were human leukocyte antigen–matched siblings in 1,692 patients, unrelated donors in 639 patients, and other related donors in 113 patients. Results Overall survival rates at 15 years were 88% (95% CI, 86% to 90%) for sibling HCT and 87% (95% CI, 83% to 90%) for unrelated donor HCT. Corresponding cumulative incidences of relapse were 8% (95% CI, 7% to 10%) and 2% (95% CI, 1% to 4%), respectively. The latest relapse was reported 18 years post-HCT. In multivariable analyses, history of chronic graft-versus-host disease increased risks of late overall mortality and nonrelapse mortality but reduced risks of relapse. In comparison with age-, race-, and sex-adjusted normal populations, the mortality of HCT recipients was significantly higher until 14 years post-HCT; thereafter, mortality rates were similar to those of the general population (relative mortality ratio at 15 years, 2.3; 95% CI, 0 to 4.9). Conclusion Recipients of allogeneic HCT for CML in first chronic phase who remain in remission for at least 5 years have favorable subsequent long-term survival, and their mortality rates eventually approach those of the general population.

    Despite the favorable prognosis of most patients with Hodgkin's Lymphoma (HL), 15–20% of patients remain refractory to chemoradiotherapy, and 20–40% experience relapses following autologous stem cell transplantation (SCT) being used as salvage approach in this situation. Long-term survival of only 20% was reported for patients who failed this option. As some authors suggested the presence of a graft versus HL effect, allogeneic SCT was introduced as a further option. Myeloablative strategies were reported to be able to achieve cure in some younger patients, but high nonrelapse mortality remains a problem. Reduced intensity conditioning, in turn, was found to be associated with high posttransplant relapse rates. As there is currently no standard in the management of HL patients who failed autologous SCT, we here review the literature on allogeneic stem cell transplantation in HL patients with a special focus on the outcomes and risk factors being reported in the largest studies.

    Risk stratification is important to identify acute myeloid leukemia (AML) patients that might benefit from allogeneic hematopoietic stem cell transplantation (allo-HCT) in first complete remission (CR1). We retrospectively studied 150 AML patients with diagnostic cytogenetic abnormalities receiving myeloablative allo-HCT in CR1 to determine the prognostic impact of persistent cytogenetic abnormalities at allo-HCT. Three risk groups were identified: First group of patients with favorable/intermediate cytogenetics at diagnosis (n=49) and the second group with unfavorable cytogenetics at diagnosis but without the presence of persistent abnormal clone at allo-HCT (n=83) had similar 3-year leukemia free survival (LFS) of 58%-60% despite increased 3-year relapse incidence (RI) of 32.3% observed in the second risk group versus 16.8% in the first group. Third group of patients with unfavorable cytogenetics at diagnosis and persistence of that clone at allo-HCT (n=15) represented the worst prognostic group with 3-year RI of 57.5% and 3-year LFS of 29.2%. These data suggest that AML patients with unfavorable cytogenetics at diagnosis and persistence of abnormal clone at allo-HCT have high risk of relapse after allo-HCT. These patients should be considered for clinical trials designed to optimize conditioning regimens and/or to use preemptive strategies in the post-transplant setting to decrease the relapse incidence.

    Allogeneic hematopoietic stem cell transplantation (HSCT) represents the only curative treatment for patients with myelodysplastic syndrome (MDS), but involves non-negligible morbidity and mortality. Registry studies have shown that advanced disease stage at transplantation is associated with inferior overall survival. To define the optimal timing of allogeneic HSCT, we carried out a decision analysis by studying 660 patients who received best supportive care and 449 subjects who underwent transplantation. Risk assessment was based on both the International Prognostic Scoring System (IPSS) and the World Health Organization classification-based Prognostic Scoring System (WPSS). We used a continuous-time multistate Markov model to describe the natural history of disease and evaluate the effect of allogeneic HSCT on survival. This model estimated life expectancy from diagnosis according to treatment policy at different risk stages. Relative to supportive care, estimated life expectancy increased when transplantation was delayed from the initial stages until progression to intermediate-1 IPSS-risk or to intermediate WPSS-risk stage, and then decreased for higher risks. Modeling decision analysis on WPSS versus IPSS allowed better estimation of the optimal timing of transplantation. These observations indicate that allogeneic HSCT offers optimal survival benefits when the procedure is performed before MDS patients progress to advanced disease stages. Am. J.

    Even if Chronic lymphocytic leukemia (CLL) often has an indolent behavior with good responsiveness to cytoreductive treatment, about 20% of the patients, so called “poor-risk” patients, show an aggressive course and die within a few years despite early intensive therapies. Criteria for poor-risk disease according to the European Bone Marrow Transplantation (EBMT) CLL Transplant Consensus are: purine analogue refractoriness, early relapse after purine analogue combination therapy, CLL with p53 lesion requiring treatment. Allogeneic transplant has potential curative role in CLL, however burden with very high transplant related mortality (TRM) rates of 38–50%. A major advance in reducing the short-term morbidity and mortality of allogeneic stem cell transplantation (SCT) has been the introduction of non-myeloablative or reduced intensity conditioning (RIC) regimens to allow engraftment of allogeneic stem cells. There is no doubt that the crucial therapeutic principle of allo-SCT in CLL is graft versus leukemia (GVL) activity. The major complications of allogeneic SCT in CLL are: chronic graft-versus-host-disease (GVHD) affecting quality of life, high graft rejection and infection rates correlated with preexisting immunosuppression. Disease relapse remains the major cause of failure after RIC allo-HCT in CLL patients. Sensitive minimal residual disease (MRD) quantification has strong prognostic impact after transplant.

    Reduced-intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (allo-HCT) can cure patients with AML in CR. However, relapse after RIC allo-HCT may indicate heterogeneity in the stringency of CR. Strict definition of CR requires no evidence of leukemia by both morphologic and flow cytometric criteria. We re-evaluated 85 AML patients receiving RIC allo-HCT in CR to test if a strict definition of CR had direct implications for the outcome. These patients had leukemia immunophenotype documented at diagnosis and analyzed at allo-HCT. Eight (9.4%) had persistent leukemia by flow cytometric criteria at allo-HCT. The patients with immunophenotypic persistent leukemia had a significantly increased relapse (hazard ratio (HR): 3.7; 95% confidence interval (CI): 1.3-10.3, P=0.01) and decreased survival (HR: 2.9; 95% CI: 1.3-6.4, P<0.01) versus 77 patients in CR by both morphology and flow cytometry. However, the pre-allo-HCT bone marrow (BM) blast count (that is, 0-4%) was not significantly associated with risks of relapse or survival. These data indicate the presence of leukemic cells, but not the BM blast count affects survival. A strict morphologic and clinical lab flow cytometric definition of CR predicts outcomes after RIC allo-HCT, and therefore is critical to achieve at transplantation. PMID:23933764

    At the most basic level, success of an allogeneic hematopoietic cell transplantation (HCT) procedure relies upon the engraftment of recipients with donor hematopoietic stem cells (HSCs) that will generate blood formation for the life of that individual. The formula to achieve durable HSC engraftment involves multiple factors including the recipient conditioning regimen, the nature of the genetic disparity between donor and recipient, and the content of the hematopoietic graft. Animal and clinical studies have shown that the biology of host resistance is complex, involving both immune and nonimmune elements. In this article, we review the factors that contribute to host resistance, describe emerging concepts on the basic biology of resistance, and discuss hematopoietic resistance as it relates specifically to patients with severe combined immunodeficiencies (SCID)— disorders that bring unique insights into the dynamics of cell replacement by allogeneic HSCs and progenitor cells.

The purpose of this study was to quantify and visualize both the demand and unmet need for HCT. Methods: HCT use for 2012 was described using the Center for International Blood and Marrow Transplant Research registry. Potential demand for HCT was calculated using 2012 SEER data and published literature for HCT-treatable conditions. Point locations of transplant centers were geocoded using geographic information system (GIS) software; Thiessen polygons were created to establish adult (age 20 to 74 years) and pediatric (age 0 to 19 years) market areas. Market-area population estimates were calculated using 2012 population estimates by age aggregated by census block. Results: US market areas for HCTs were identified separately for transplant centers treating adult (n = 62) and pediatric patients (n = 52). Overall HCT demand among adults was 16,096, with an unmet need for HCTs of 10,276 patients. For pediatric patients, the total demand was 4,561, with an unmet need of 3,213 potential recipients. Evaluation of adult and pediatric market areas indicated that the largest unmet needs tended to be in areas with large populations. Conclusion: Market-area maps and statistics developed using GIS will help communicate the unmet need for HCT, inform policy, and assist transplant centers in planning for the anticipated growth in HCT use.

    Peripheral T-cell and NK-cell lymphomas (PT/NKCL) are a heterogeneous group of lymphoid neoplasms with poor outcomes. There is no consensus on the best front line therapy or management of relapsed/refractory disease. The use of autologous and allogeneic hematopoietic cell transplantation (HCT) has been studied in both settings to improve outcomes. Multiple retrospective and several prospective trials were reported. While at first sight the outcomes in the relapsed/refractory setting appear similar in B-cell and T-cell lymphomas when treated with high dose therapy (HDT) and autologous HCT, it is becoming obvious that only specific subtypes of PTCL benefit from this approach (i.e. anaplastic large cell lymphoma [ALCL] and angioimmunoblastic lymphoma [AITL] in second CR). In less favorable histologies, HDT seems to provide limited benefit, with the majority of patients experiencing post-transplant relapse. The use of autologous HCT to consolidate first remission has been evaluated in several prospective trials. Again, the best results were observed in ALCL, but the superiority of this approach over chemotherapy alone needs confirmation in randomized trials. In less favorable histologies, high-dose consolidation resulted in low survival rates comparable to those obtained with chemotherapy alone, and without randomized trials it is hard to recommend this strategy to all patients with newly diagnosed PT/NKCL. Allogeneic HCT might provide potent and potentially curative graft-vs-lymphoma effect and overcome chemotherapy resistance. Only a few studies have been reported to date on allogeneic HCT in PT/NKCL. Based on available data, eligible patients benefit significantly from this approach, with 50% or more patients achieving long-term disease control or cure, although at the expense of significant treatment related mortality (TRM). Reduced-intensity conditioning regimens appear to have lower TRM and might extend this approach to older patients. With the recent approval of

    Allogeneic (allo) hematopoietic cell transplantation (HCT) has evolved into a potent curative treatment option for a variety of malignant and nonmalignant diseases. The occurrence of complications and mortality after allo-HCT is, however, still high and is strongly associated with immune reconstitution (IR). Therefore, detailed information on IR through immunomonitoring is crucial to improve survival chances after HCT. To date, information about the reconstituting immune system after allo-HCT in pediatric patients is mostly derived from routine standard-of-care measurements. More profound knowledge on IR may provide tools to better predict and modulate adverse reactions and, subsequently, improve survival chances. Here, we provide an overview of IR (eg, immune cell subsets and circulating chemokines/cytokines) after allo-HCT in children, taking into account different cell sources and serotherapy, and discuss strategies to enhance immunomonitoring. We conclude that available IR data after allo-HCT contain limited information on immune cell families (mostly only generic T, B, and NK cells), which would improve with more detailed information on reconstituting cell subsets or effector cell functionality at earlier time points (<1 month). In addition, secretome data (eg, multiplex cytokine/chemokine profiles) could add to the understanding of IR mechanisms and cell functionality and may even provide (early) biomarkers for individual disease outcome, such as viral reactivity, graft-versus-host disease, or graft-versus-leukemia. The present data and suggestions for more detailed, standardized, and harmonized immunomonitoring in future (pediatric) allo-HCT studies will pave the path to "precision transplantation:" an individualized HCT approach (including conditioning), based on detailed information on IR and biomarkers, aiming to reduce transplantation related mortality and relapse, and subsequently improve survival chances.

    Autologous hematopoietic stem cell transplantation (auto-HCT) is considered a standard therapy for transplant-eligible patients with multiple myeloma, while allogeneic HCT (allo-HCT) is controversial. We retrospectively analyzed 765 patients with myeloma who underwent tandem transplantation between 1998 and 2012 using Japanese registry data. We evaluated the clinical outcomes of tandem auto-HCT (n = 676) and auto/allo-HCT (n = 89). To adjust for a selection bias, we compared overall survival (OS) between the two groups by a propensity score analysis. The probability of OS at six years was 58.5% for the tandem auto-HCT group and 54.4% for the tandem auto/allo-HCT group (p = 0.47). In a matched-pair analysis based on the propensity score, the difference in survival between the two groups was not statistically significant, although the survival curve appeared to reach a plateau beyond five years in the auto/allo group. Further strategies to reduce treatment-related mortality and enhance a graft-versus-myeloma effect are necessary to improve OS. PMID:26961137

    Both European Group for blood and marrow transplantation risk score (EBMT score modified model) and hematopoietic cell transplantation comorbidity index (HCT-CI) are suitable for evaluating patients undergoing unmanipulated haploidentical blood and marrow transplantation (HBMT), while the predictive capacity of the combined model following haploidentical transplantation is still unknown. In this study, we calculated and validated 322 consecutive unmanipulated HBMT patients. Patients in groups with HCT-CI scores of 0 or 1-2 exhibited similar overall survival (OS), non-relapse mortality (NRM), and relapse rates, independent of their EBMT score modified model. In the group in which patients' HCT-CI scores were ≥3, patients with high EBMT score modified model showed lower OS (p = 0.003) and higher NRM (p = 0.001) than did patients with low EBMT score. In conclusion, this combined model can be used to predict outcomes and may improve the stratification of high-risk patients following unmanipulated HBMT. PMID:26857549

    Purpose: Approximately 5% to 20% of patients who undergo total body irradiation (TBI) in preparation for hematopoietic cell transplantation (HCT) can develop extramedullary (EM) relapse. Whereas total marrow and lymphoid irradiation (TMLI) provides a more conformally targeted radiation therapy for patients, organ sparing has the potential to place the patient at a higher risk for EM relapse than TBI. This study evaluated EM relapse in patients treated with TMLI at our institution. Methods and Materials: Patients eligible for analysis had been enrolled in 1 of 3 prospective TMLI trials between 2006 and 2012. The TMLI targeted bones, major lymph node chains, liver, spleen, testes, and brain, using image-guided tomotherapy with total dose ranging from 12 to 15 Gy. Results: A total of 101 patients with a median age of 47 years were studied. The median follow-up was 12.8 months. Incidence of EM relapse and bone marrow (BM) relapse were 12.9% and 25.7%, respectively. Of the 13 patients who had EM relapse, 4 also had BM relapse, and 7 had EM disease prior to HCT. There were a total of 19 EM relapse sites as the site of initial recurrence: 11 soft tissue, 6 lymph node, 2 skin. Nine of these sites were within the target region and received ≥12 Gy. Ten initial EM relapse sites were outside of the target region: 5 sites received 10.1 to 11.4 Gy while 5 sites received <10 Gy. Pretransplantation EM was the only significant predictor of subsequent EM relapse. The cumulative incidence of EM relapse was 4% at 1 year and 11.4% at 2 years. Conclusions: EM relapse incidence was as frequent in regions receiving ≥10 Gy as those receiving <10 Gy. EM relapse rates following TMLI that included HCT regimens were comparable to published results with regimens including TBI and suggest that TMLI is not associated with an increased EM relapse risk.

    Family caregivers of allogeneic hematopoietic stem cell transplant (HSCT) patients are at risk for experiencing significant psychological distress yet screening caregivers has not been well studied. Objective This analysis explored the psychometric characteristics of the Distress Thermometer (DT) by examining its relationship, sensitivity and specificity relative to the Brief Symptom Inventory 18 (BSI-18) and the Multidimensional Fatigue Symptom Inventory (MFSI) in a sample of allogeneic HSCT caregivers and patients. Methods Longitudinal data were drawn from an ongoing intervention study for HSCT caregivers and patients. Data from one hundred and fifty-six English-speaking adults where patients (n=65) were receiving their first allogeneic HSCT with at least one adult caregiver (n=91) were eligible for this analysis. Study questionnaires were administered at baseline, initial discharge and 6 weeks following discharge. Results Construct validity was supported by significant relationships (p<0.001) between the DT and the BSI-18 GSI and the MFSI-Emotional subscales for caregivers and patients. The diagnostic utility of the DT for patients was good (AUC=.85±.05, p=.001), while for caregivers it was poor (AUC=.61±.08, p=.28). A DT cut point of 5 was supported for patients (sensitivity=1.0, specificity=.68), while for caregivers there was less confidence (sensitivity=.70, specificity=.52). Caregivers and patients reporting a higher number of problems had a greater level of distress (p<0.001). Conclusions These findings support the validity of the DT in screening for distress in HSCT caregivers and patients. Although the diagnostic utility of the DT for HSCT caregivers may be limited, understanding factors associated with distress can guide practice for this understudied population. PMID:21626610

    Engraftment syndrome (ES) encompasses a constellation of symptoms that occur during neutrophil recovery after both autologous and allogeneic hematopoietic stem cell transplantation (HCT). Although it is well characterized after conventional myeloablative procedures, limited data exist on this complication after nonmyeloablative allogeneic HCT. The clinical manifestations, incidence, and risk factors associated with ES were investigated in a consecutive series of patients undergoing cyclophosphamide/fludarabine-based nonmyeloablative allogeneic HCT from a related HLA-compatible donor. Fifteen (10%) of 149 patients (median age, 53 years; range, 27-66 years) developed ES; the onset of symptoms occurred at a median of 10 days (range, 3-14 days), and they consisted of fever (100%), cough (53%), diffuse pulmonary infiltrates (100%), rash (13%), and room air hypoxia (87%). ES was more likely to develop in patients who received empiric amphotericin formulations after transplant conditioning (Fisher exact test; P=.007). In a multivariate analysis, older patient age, female sex, and treatment with amphotericin were predictors for the development of ES. Intravenous methylprednisolone led to the rapid resolution of ES; however, transplant-related mortality was significantly higher (cumulative incidence, 49% versus 16%; P=.0005), and median survival was significantly shorter (168 versus 418 days; P=.005) in patients with ES compared with non-ES patients. In conclusion, ES occurs commonly after cyclophosphamide/fludarabine-based nonmyeloablative transplantation and responds rapidly to corticosteroid treatment, but it is associated with a higher risk of nonrelapse mortality and with shorter overall survival.

    Allogeneic hematopoietic stem cell transplantation (HSCT) is a potentially curative option for patients with myelodysplastic syndrome (MDS). Because MDS predominantly affects an older population, age-associated comorbidities can preclude patients from cure. HSCT is associated with the risk of morbidity and mortality; however, with safer conditioning regimens and improved supportive care, eligible patients with an appropriately matched donor can receive this therapy without exclusion by older age alone. We discuss the role of improved MDS prognostic scoring systems and molecular testing for selection for HSCT, and review the pre-HSCT tolerability assessment required for this advanced aged population.

    Molecular predictors of outcome are increasingly important in determining optimal therapy for myeloid neoplasms. Mutations in the spliceosomal genes (U2AF1 and SRSF2) predict for poor outcomes in myelodysplastic syndromes (MDS) and related diseases. We investigated the effect of hematopoietic cell transplant (HCT) on the negative prognostic impact of U2AF1 and SRSF2 mutations. In total, 122 patients with MDS (30%), acute myeloid leukemia (51%), myeloproliferative neoplasms (MPN) (11%), and MDS/MPN (8%) receiving a HCT from 2003 to 2012 were evaluated for mutations in U2AF1 and SRSF2 by direct sequencing. Median time of follow up was 24 months (range 0.46-110). SRSF2 mutations were detected in 11 (10%) patients and U2AF1 in 3 (3%) patients. There were no significant differences in baseline characteristics between mutated and wild-type (WT) patients. Patients carrying SRSF2 and U2AF1 mutations had similar overall survival (P = 0.84), relapse mortality (P = 0.50), and non-relapse mortality (P = 0.72) compared to WT patients. However, taking into account disease status and cytogenetics in a subset of AML patients, SRSF2 and U2AF1 mutations were associated with worse survival (HR 3.71, P = 0.035). Am. J.

    Background The mouth is a complex biological structure inhabited by diverse bacterial communities. The purpose of this study is to describe the effects of allogeneic stem cell transplantation on the oral microbiota and to examine differences among those patients who acquired respiratory complications after transplantation. Methodology/Principal Findings All patients were consented at the National Institutes of Health, Clinical Center. Bacterial DNA was analyzed from patients' oral specimens using the Human Oral Microbe Identification Microarray. The specimens were collected from four oral sites in 45 allogeneic transplantation patients. Specimens were collected at baseline prior to transplantation, after transplantation at the nadir of the neutrophil count and after myeloid engraftment. If respiratory signs and symptoms developed, additional specimens were obtained. Patients were followed for 100 days post transplantation. Eleven patients' specimens were subjected to further statistical analysis. Many common bacterial genera, such as Streptococcus, Veillonella, Gemella, Granulicatella and Camplyobacter were identified as being present before and after transplantation. Five of 11 patients developed respiratory complications following transplantation and there was preliminary evidence that the oral microbiome changed in their oral specimens. Cluster analysis and principal component analysis revealed this change in the oral microbiota. Conclusions/Significance After allogeneic transplantation, the oral bacterial community's response to a new immune system was not apparent and many of the most common core oral taxa remained unaffected. However, the oral microbiome was affected in patients who developed respiratory signs and symptoms after transplantation. The association related to the change in the oral microbiota and respiratory complications after transplantation will be validated by future studies using high throughput molecular methods.

    Part I of this article included a pertinent review of allogeneic hematopoietic cell transplantation (alloHCT), the role of postgraft immunosuppression in alloHCT, and the pharmacokinetics, pharmacodynamics, and pharmacogenomics of the calcineurin inhibitors and methotrexate. In this article (Part II), we review the pharmacokinetics, pharmacodynamics, and pharmacogenomics of mycophenolic acid (MPA), sirolimus, and the antithymocyte globulins (ATG). We then discuss target concentration intervention (TCI) of these postgraft immunosuppressants in alloHCT patients, with a focus on current evidence for TCI and on how TCI may improve clinical management in these patients. Currently, TCI using trough concentrations is conducted for sirolimus in alloHCT patients. Several studies demonstrate that MPA plasma exposure is associated with clinical outcomes, with an increasing number of alloHCT patients needing TCI of MPA. Compared with MPA, there are fewer pharmacokinetic/dynamic studies of rabbit ATG and horse ATG in alloHCT patients. Future pharmacokinetic/dynamic research of postgraft immunosuppressants should include '-omics'-based tools: pharmacogenomics may be used to gain an improved understanding of the covariates influencing pharmacokinetics as well as proteomics and metabolomics as novel methods to elucidate pharmacodynamic responses.

    Biologic markers of immune tolerance may facilitate tailoring of immune suppression duration after allogeneic hematopoietic cell transplantation (HCT). In a cross-sectional study, peripheral blood samples were obtained from tolerant (n = 15, median 38.5 months post-HCT) and non-tolerant (n = 17, median 39.5 post-HCT) HCT recipients and healthy control subjects (n = 10) for analysis of immune cell subsets and differential gene expression. There were no significant differences in immune subsets across groups. We identified 281 probe sets unique to the tolerant (TOL) group and 122 for non-tolerant (non-TOL). These were enriched for process networks including NK cell cytotoxicity, antigen presentation, lymphocyte proliferation, and cell cycle and apoptosis. Differential gene expression was enriched for CD56, CD66, and CD14 human lineage-specific gene expression. Differential expression of 20 probe sets between groups was sufficient to develop a classifier with > 90% accuracy, correctly classifying 14/15 TOL cases and 15/17 non-TOL cases. These data suggest that differential gene expression can be utilized to accurately classify tolerant patients following HCT. Prospective investigation of immune tolerance biologic markers is warranted. PMID:25774806

    Ibrutinib, a recently approved inhibitor of Bruton's tyrosine kinase (BTK), has shown great efficacy in patients with high-risk CLL. Nevertheless, there are few data regarding its use in patients who relapsed after allogeneic stem cell transplantation (alloSCT). We report clinical data from five CLL patients treated with ibrutinib for relapse after first or even second allogeneic transplantation. Additionally, we performed analyses on cytokine levels and direct measuring of CD4 Th1 and CD4 Th2 cells to evaluate possible clinically relevant immunomodulatory effects of ibrutinib. All patients achieved partial responses including one minimal residual disease (MRD)-negative remission. Within 1 year of follow-up, no relapse was observed. One patient died of severe pneumonia while on ibrutinib treatment. Beside this, no unexpected adverse events were observed. Flow cytometry and analyses of T cell-mediated cytokine levels (IL10 and TNFα) did not reveal substantial changes in T-cell distribution in favor of a CD4 Th1 T-cell shift in our patients. No acute exacerbation of GvHD was reported. In conclusion, these results support further evaluation of ibrutinib in CLL patients relapsing after alloSCT. PMID:26752141

We report on a female patient with MPS I treated by allogeneic bone marrow transplantation (BMT) at the age of 4 years (after a conditioning regimen containing busulfan 16 mg/kg and cyclophosphamide 100 mg/kg) who had four successful pregnancies without any reproductive assistance. Clinical and biological examinations of the children were normal. On the basis of this case, we discuss the fertility counselling of female MPS I patients at the time of BMT. PMID:19280364

    Hematopoietic cell transplantation (HCT) can cure bone marrow failure in patients with Fanconi Anemia (FA), and it is generally accepted that these patients should receive low-intensity conditioning because of the underlying DNA repair defect in their cells. Outcomes for recipients of matched related HCT have generally been favorable, but only a few studies have scrutinized the factors that may affect the eventual outcome of these patients. This retrospective analysis of 94 pediatric patients with FA who underwent related HCT at King Faisal Specialist Hospital & Research Center was carried out to attempt to identify factors that may affect outcome. Results showed overall survival (OS) probabilities of 92.5%, 89%, and 86% at 1, 5, and 10 years, respectively. In univariate analysis, use of higher dose cyclophosphamide (CY) (60 mg/kg) conditioning was associated with a better 10-year OS than lower dose CY (20 mg/kg) conditioning (91% versus 82%, respectively; P = .035), and use of radiation-containing regimens was associated with a significantly lower 10-year OS than nonradiation regimens (76% versus 91%, respectively; P = .005). Of the 4 regimens used in this study, the fludarabine-based regimen was associated with the highest survival (95.2%; P = .034). The use of the higher dose CY (60 mg/kg) was associated with a significantly increased incidence of hemorrhagic cystitis (HC) (20% versus 5.6% respectively; P = .049). Three patients (3%) developed squamous cell carcinoma (2 oropharyngeal and 1 genitourinary), at 9.4, 5.4, and 13.3 years after HCT; 2 of them had radiation-containing conditioning. In conclusion, our data suggest that although using a higher dose CY (60 mg/kg) conditioning regimen may be associated with better survival, it is also associated with a significantly increased risk of HC. The addition of fludarabine to the low-dose CY (20 mg/kg) is associated with the best survival. On the other hand, radiation-containing regimens are associated with

    Purpose of review The optimal post-remission therapy of acute myeloid leukemia (AML) in first complete remission (CR1) is uncertain. This review summarizes the recent developments in the clinical research and therapeutic applications defining the role of allogeneic hematopoietic stem cell transplantation (allo-HCT) in CR1. Recent findings Molecular markers in combinations with cytogenetics have improved the risk stratification and informed decision-making in patients with AML in CR1. In parallel, several important advances in the transplant field, such as better supportive care, improved transplant technology, increased availability of alternative donors, and reduced-intensity conditioning have improved the safety as well as access of allo-HCT for a larger number of patients. Summary The progress in risk stratification and transplant technology dictate that early donor identification search should be initiated for all eligible AML patients in CR1. PMID:21912256

    Mesenchymal stem cells (MSCs) can show osteogenic differentiation capability when implanted in vivo, as well as cultured in vitro; therefore we attempted to use allogeneic MSCs for an 8-month-old patient with hypophosphatasia. MSCs were obtained by culture expansion of fresh marrow from the patient's father. Some of the MSCs were further cultured under osteogenic conditions on a culture dish or porous hydroxyapatite ceramics, resulting in cultured osteoblasts and osteogenic constructs, respectively. The MSCs and osteoblasts were injected into the patient, and the constructs were implanted locally. After traditional bone marrow transplantation, the MSCs, osteoblasts, and osteogenic constructs were used for treatment and to improve the patient's respiratory condition and skeletal abnormality. The condition worsened again, and an MSC booster shot was administered. At the same time, the construct was retrieved. The respiratory condition improved, and the retrieved construct showed de novo bone derived from both donor and patient cells. We demonstrated the importance of allogeneic MSC transplantation for hypophosphatasia and the constructs as an alternative to bone fragments that provided further osteogenic capability in the patient.

    Because a pediatric-inspired Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL) protocol yielded a markedly improved outcome in adults with Philadelphia chromosome-negative ALL, we aimed to reassess the role of allogeneic stem cell transplantation (SCT) in patients treated in the GRAALL-2003 and GRAALL-2005 trials. In all, 522 patients age 15 to 55 years old and presenting with at least 1 conventional high-risk factor were candidates for SCT in first complete remission. Among these, 282 (54%) received a transplant in first complete remission. At 3 years, posttransplant cumulative incidences of relapse, nonrelapse mortality, and relapse-free survival (RFS) were estimated at 19.5%, 15.5%, and 64.7%, respectively. Time-dependent analysis did not reveal a significant difference in RFS between SCT and no-SCT cohorts. However, SCT was associated with longer RFS in patients with postinduction minimal residual disease (MRD) ≥10(-3) (hazard ratio, 0.40) but not in good MRD responders. In B-cell precursor ALL, SCT also benefitted patients with focal IKZF1 gene deletion (hazard ratio, 0.42). This article shows that poor early MRD response, in contrast to conventional ALL risk factors, is an excellent tool to identify patients who may benefit from allogeneic SCT in the context of intensified adult ALL therapy.

    We assessed the long-term outcome of patients with relapsed acute myeloid (n=86) or acute lymphoid leukemia (n=66), undergoing an allogeneic hemopoietic stem cell transplantation in our unit. The median blast count in the marrow was 30%. Conditioning regimen included total body irradiation (TBI) (10-12 Gy) in 115 patients. The donor was a matched donor (n=132) or a family mismatched donor (n=20). Twenty-two patients (15%) survive disease free, with a median follow-up of 14 years: 18 are off medications. The cumulative incidence of transplant related mortality is 40% and the cumulative incidence of relapse related death (RRD) is 45%. In multivariate analysis of survival, favorable predictors were chronic graft-versus-host disease (GvHD) (P=0.0003), donor other than family mismatched (P=0.02), donor age less than 34 years (P=0.02) and blast count less than 30% (P=0.07). Patients with all four favorable predictors had a 54% survival. In multivariate analysis of relapse, protective variables were the use of TBI (P=0.005) and cGvHD (P=0.01). This study confirms that a fraction of relapsed leukemias is cured with an allogeneic transplant: selection of patients with a blast count <30%, identification of young, human leukocyte antigen-matched donors and the use of total body radiation may significantly improve the outcome.

    Purpose Allogeneic hematopoietic cell transplantation (HCT) is curative but is associated with life-threatening complications. Most deaths occur within the first 2 years after transplantation. In this report, we examine long-term survival in 2-year survivors in the largest cohort ever studied. Patients and Methods Records of 10,632 patients worldwide reported to the Center for International Blood and Marrow Transplant Research who were alive and disease free 2 years after receiving a myeloablative allogeneic HCT before 2004 for acute myelogenous or lymphoblastic leukemia, myelodysplastic syndrome, lymphoma, or severe aplastic anemia were reviewed. Results Median follow-up was 9 years, and 3,788 patients had been observed for 10 or more years. The probability of being alive 10 years after HCT was 85%. The chief risk factors for late death included older age and chronic graft-versus-host disease (GVHD). For patients who underwent transplantation for malignancy, relapse was the most common cause of death. The greatest risk factor for late relapse was advanced disease at transplantation. Principal risk factors for nonrelapse deaths were older age and GVHD. When compared with age, sex, and nationality-matched general population, late deaths remained higher than expected for each disease, with the possible exception of lymphoma, although the relative risk generally receded over time. Conclusion The prospect for long-term survival is excellent for 2-year survivors of allogeneic HCT. However, life expectancy remains lower than expected. Performance of HCT earlier in the course of disease, control of GVHD, enhancement of immune reconstitution, less toxic regimens, and prevention and early treatment of late complications are needed.

    Allogeneic hematopoietic cell transplantation (HCT) is a potentially curative approach in patients with multiple myeloma, but its use for consolidation of first remission has not yet been fully explored. Twenty-two myeloma patients with very good partial response (VGPR) or CR received allogeneic peripheral blood grafts as consolidation from HLA-matched donors between 2007 and 2012. Conditioning regimens were fludarabine (30 mg/m(2) i.v. if with bortezomib and 40 mg/m(2) i.v. when without bortezomib, × 4 days) plus melphalan (70 mg/m(2) intravenously × 2 days) with (n=13) or without (n=9) bortezomib (1.3 mg/m(2)). The cumulative incidence of grades II - IV acute GVHD at day 100 was 45% (95% CI: 24-65%) and moderate-to-severe chronic GVHD at 2 years was 46% (95% CI: 19-69%). With a median follow-up of 18 (range, 2-61) months, the 2-year PFS estimate is 74.8% (95% CI: 45-90%), which compares favorably with the 52% (95% CI: 35-66%) after autologous HCT for similar patients (a median follow-up of 30 (range, 9-55) months). We are conducting a phase 2 study to assess the efficacy of allogeneic HCT as post-remission therapy. PMID:23542223

    Optimal therapy for relapsed APL in pediatric patients is controversial. Allogeneic HSCT is an alternative, with event-free survival of 70-75%. We report a pediatric patient with APL who relapsed 28 months after CBT from her sibling and then was treated with BMT from the same donor. Bone marrow was selected for higher cell dose, donor availability, and partial donor chimerism. Persistent molecular remission was achieved, currently at 65 months after BMT. This case suggests the potential role of GVL activity in APL and illustrates the use of different cell sources from the same donor in allogeneic transplantation for pediatric patients. PMID:26849401

    Mycophenolic acid, the active metabolite of mycophenolate mofetil (MMF), inhibits inosine monophosphate dehydrogenase (IMPDH) activity. IMPDH is the rate-limiting enzyme involved in de novo synthesis of guanosine nucleotides and catalyzes the oxidation of inosine 5’- monophosphate (IMP) to xanthosine 5’-monophosphate (XMP). We developed a highly sensitive liquid chromatography–mass spectrometry method to quantitate XMP concentrations in peripheral blood mononuclear cells (PMNC) isolated from the recipient pretransplant and used this method to determine IMPDH activity in 86 nonmyeloablative allogeneic hematopoietic cell transplantation (HCT) patients. The incubation procedure and analytical method yielded acceptable within-sample and within-individual variability. Considerable between-individual variability was observed (12.2-fold). Low recipient pretransplant IMPDH activity was associated with increased day +28 donor T-cell chimerism, more acute graft-versus-host disease (GVHD), lower neutrophil nadirs, and more cytomegalovirus reactivation, but not with chronic GVHD, relapse, non-relapse mortality, or overall mortality. We conclude that quantitation of the recipient’s pretransplant IMPDH activity in PMNC lysate could provide a useful biomarker to evaluate a recipient’s sensitivity to MMF, but confirmatory studies are needed. Further trials should be conducted to confirm our findings and to optimize postgrafting immunosuppression in nonmyeloablative HCT recipients. PMID:24923537

    T315I+ Philadelphia chromosome–positive leukemias are inherently resistant to all licensed tyrosine kinase inhibitors, and therapeutic options remain limited. We report the outcome of allogeneic stem cell transplantation in 64 patients with documented BCR-ABLT315I mutations. Median follow-up was 52 months from mutation detection and 26 months from transplantation. At transplantation, 51.5% of patients with chronic myeloid leukemia were in the chronic phase and 4.5% were in advanced phases. Median overall survival after transplantation was 10.3 months (range 5.7 months to not reached [ie, still alive]) for those with chronic myeloid leukemia in the blast phase and 7.4 months (range 1.4 months to not reached [ie, still alive]) for those with Philadelphia chromosome–positive acute lymphoblastic leukemia but has not yet been reached for those in the chronic and accelerated phases of chronic myeloid leukemia. The occurrence of chronic GVHD had a positive impact on overall survival (P = .047). Transplant-related mortality rates were low. Multivariate analysis identified only blast phase at transplantation (hazard ratio 3.68, P = .0011) and unrelated stem cell donor (hazard ratio 2.98, P = .011) as unfavorable factors. We conclude that allogeneic stem cell transplantation represents a valuable therapeutic tool for eligible patients with BCR-ABLT315I mutation, a tool that may or may not be replaced by third-generation tyrosine kinase inhibitors.

    Here we present a male patient with acute myeloid leukemia (AML) initially diagnosed as M5 and with karyotype 46,XY. After induction therapy, he underwent a HLA-matched allogeneic hematopoietic stem cell transplantation, and six years later he relapsed as AML M1 with an abnormal karyotype //47,XX,+10[2]/47,XX,+11[3]/48,XX,+10,+11[2]/46,XX[13]. Based on this, we tested the possibility of donor cell origin by FISH and molecular STR analysis. We found no evidence of Y chromosome presence by FISH and STR analysis consistent with the success of the allogeneic hematopoietic stem cell transplantation from the female donor. FISH studies confirmed trisomies and no evidence of MLL translocation either p53 or ATM deletion. Additionally 28 fusion common leukemia transcripts were evaluated by multiplex reverse transcriptase-polymerase chain reaction assay and were not rearranged. STR analysis showed a complete donor chimerism. Thus, donor cell leukemia (DCL) was concluded, being essential the use of cytological and molecular approaches. Pediatric DCL is uncommon, our patient seems to be the sixth case and additionally it presented a late donor cell leukemia appearance. Different extrinsic and intrinsic mechanisms have been considered to explain this uncommon finding as well as the implications to the patient. PMID:25674158

    Enzyme-linked immunosorbent assays (ELISAs) have traditionally been used to detect alloantibodies in patient plasma samples post hematopoietic cell transplantation (HCT); however, protein microarrays have the potential to be multiplexed, more sensitive, and higher throughput than ELISAs. Here, we describe the development of a novel and sensitive microarray method for detection of allogeneic antibodies against minor histocompatibility antigens encoded on the Y chromosome, called HY antigens. Six microarray surfaces were tested for their ability to bind recombinant protein and peptide HY antigens. Significant allogeneic immune responses were determined in male patients with female donors by considering normal male donor responses as baseline. HY microarray results were also compared with our previous ELISA results. Our overall goal was to maximize antibody detection for both recombinant protein and peptide epitopes. For detection of HY antigens, the Epoxy (Schott) protein microarray surface was both most sensitive and reliable and has become the standard surface in our microarray platform. PMID:26902899

    We studied surveillance, incidence and outcome of viral infections in children undergoing allogeneic hematopoietic cell transplantation (HCT) in the main pediatric transplant units in Spain. We prospectively collected data from first year post-HCT in every consecutive allogeneic HCT performed during 3 years (N = 215): first HCT = 188 and second HCT = 27; median age = 6.6 years (0.1-20.7). Most patients had acute leukemia (N = 137) and 135 recipients (63%) were CMV seropositive. A total of 46 patients underwent cord blood transplant, 133 patients underwent HCT from alternative donors (62%) and 101 patients received anti-thymocyte globulin. Observational time was completed in 137 patients, whereas the remaining 78 died after a median survival time of 99 days (3-352). CMV was monitored in all patients; adenovirus (ADV) and human herpesvirus 6 (HHV-6) were monitored in 101 and 33 patients, respectively. We found 145 viral infections in 103 patients: CMV (n = 42), ADV (n = 32), HHV-6 (n = 7), polyomavirus (n = 20), EBV (n = 6), VZV (n=17) and others (n = 8). CMV infection was significantly higher in seropositive patients (25 vs 7%) (P = 0.02). Extensive chronic GVHD (cGVHD) was significantly associated with an increased rate of viral infections (12 of 16 patients with cGVHD had infections vs 91 of 199 without GVHD) (P = 0.035). In total, 10 patients (4.6%) died of viral infections (CMV = 5, ADV = 3, respiratory = 2). We found a high incidence of viral infection, but mortality was low. PMID:20228849

    Allogeneic mesenchymal stromal cells (MSCs) are widely used in regenerative medicine, but little is known about their immunogenicity. In this study, we monitored the therapeutic and immunogenic effects of decidual stromal cells (DSCs) from term placentas when used as a therapy for generalized severe junctional epidermolysis bullosa (JEB) (previously termed Herlitz JEB), a lethal condition caused by the lack of functional laminin-332. An 11-month-old JEB patient was treated with five infusions of allogeneic DSCs within a 3-month period. Amniotic membranes (AMs) were applied to severe wounds. After the treatment, wounds started to heal in the middle of the blisters, but the improvements were transient. After two infusions of DSCs, the JEB patient had developed multispecific anti-HLA class-I antibodies. No antibodies to laminin-332 were detected, but the patient had high levels of anti-bovine serum albumin antibodies, which could bind to DSCs. Peripheral blood mononuclear cells (PBMCs) from the patient had a higher proliferative response to DSCs than to third-party PBMCs, which contrasts with the pattern observed in healthy donors. Human DSCs and MSCs induced similar xenoreactivity in mice. Two of 16 allogeneic stem cell-transplanted patients, treated with DSCs for graft-versus-host disease or hemorrhagic cystitis, showed a positive flow cytometric crossmatch test. One patient had anti-HLA antibodies before DSC infusion, whereas the other had no anti-HLA antibodies at any time. AM and DSC infusions may have improved the healing process in the JEB patient, but DSCs appeared to induce anti-HLA antibodies. The risk of alloimmunization by DSCs seems to be low in immunocompromised patients. PMID:25658253

    Acute kidney injury (AKI) is highly prevalent whether the patients undergo myeloablative or non-myeloablative hematopoietic cell transplantation (HCT); however, the pathogenesis and risk factors leading to AKI can differ between the two. The prognosis of AKI in patients receiving HCT is poor. In fact, AKI following HCT is associated not only with increased short- and long-term mortality, but also with progression to chronic kidney disease. Herein, the authors provide a comprehensive and up-to-date review of the definition and diagnosis, as well as of the incidence, pathogenesis and outcome of AKI in patients undergoing HCT, centering on the differences between myeloablative and non-myeloablative regimens.

    Allogeneic hematopoietic cell transplantation (HCT) was originally developed to allow delivery of myeloablative doses of chemotherapy and radiotherapy. With better understanding of disease pathophysiology, the graft vs malignancy (GVM) effect of allogeneic hematopoietic transplantation and toxicities associated with myeloablative conditioning (MAC) regimens, the focus shifted to developing less toxic conditioning regimens to reduce treatment-related morbidity without compromising survival. Although HCT with MAC is preferred to reduced intensity conditioning (RIC) for most patients ≤ 60 years with AML/myelodysplastic syndrome and ALL, RIC and nonmyeloablative (NMA) regimens allow HCT for many otherwise ineligible patients. Reduced intensity preparative regimens have produced high rates of PFS for diagnoses, which are highly sensitive to GVM. Relapse of the malignancy is the major cause of treatment failure with RIC/NMA HCT. Incorporation of novel agents like bortezomib or lenalidomide, addition of cellular immunotherapy and use of targeted radiation therapies could further improve outcome. In this review, we discuss commonly used RIC/NMA regimens and promising novel regimens. PMID:25985053

    With the introduction of nonmyeloablative conditioning, hematopoietic cell transplantation (HCT) has become a viable treatment option for patients who due to age or comorbidities are ineligible for high dose conditioning. However, relapse and toxicities are still major problems in HCT. Radioimmunotherapy (RIT)-based conditioning is a promising approach that has the ability to specifically target radiation to hematopoietic cells. The most widely investigated isotopes are the β-emitters, but because of long path lengths and low linear energy transfer, α-emitters which have more favorable physical characteristics, might prove to be a better alternative. In the current study we have investigated the efficacy and safety of α-emitter based RIT as the only form of conditioning in a preclinical model of canine allogeneic HCT. PMID:22772070

    Infectious complications, particularly viral infections, remain a significant cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (alloHCT). Only a handful of studies in children have analyzed the risks for and impact of viremia on alloHCT-related outcomes. We conducted a retrospective study of 140 pediatric patients undergoing alloHCT to investigate the incidence of and risk factors for cytomegalovirus (CMV), adenovirus (ADV), and Epstein-Barr virus (EBV) viremia and viral disease after alloHCT. Furthermore, we assessed the impact of viremia on days of hospitalization and develop an algorithm for routine monitoring of viremia. Patients were monitored before alloHCT and then weekly for 180 days after alloHCT. Patients were considered to have viremia if CMV were > 600 copies/mL, EBV were > 1000 copies/mL, or ADV were > 1000 copies/mL on 2 consecutive PCRs. The overall incidences of viremia and viral disease in all patients from day 0 to +180 after alloHCT were 41.4% (n = 58) and 17% (n = 24), respectively. The overall survival for patients with viremia and viral disease was significantly lower compared with those without viremia (58% versus 74.2%, P = .03) and viral disease (48.2% versus 71.2%, P = .024). We identified that pretransplantation CMV risk status, pre-alloHCT viremia, and use of alemtuzumab were associated with the risk of post-alloHCT viremia. The average hospitalization days in patients with CMV risk (P = .011), viremia (P = .024), and viral disease (P = .002) were significantly higher. The algorithm developed from our data can potentially reduce viral PCR testing by 50% and is being studied prospectively at our center. Improved preventative treatment strategies for children at risk of viremia after alloHCT are needed. PMID:27252110

    The outcomes of allogeneic hematopoietic cell transplantation (HSCT) in patients with biphenotypic acute leukemia (BAL) remain unclear. We retrospectively analyzed the outcomes of HSCT in BAL patients in Japan in comparison to acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) using the registration data from a nationwide database. The data of 90, 5371, and 3301 patients with BAL, AML, and ALL, respectively, were included in the analysis. The median follow-up period was 1481.5 days (range: 0–5556). The 5-year overall survival (OS) of the BAL, AML, and ALL patients were 39.6, 41.8, and 42.0 %, respectively (BAL vs. AML, P = 0.98 BAL vs. ALL, P = 0.77). A multivariate analysis revealed that, in comparison to BAL, AML with a better-risk karyotype was associated with superior OS. An analysis of the prognostic factors of BAL patients showed that OS was significantly longer in patients who were in their first complete remission in comparison to patients who were not in remission. Our data suggest that HSCT is an effective treatment for BAL patients, regardless of the presence of any known poor prognostic factors other than a non-remission status. PMID:26499506

    The objective was to evaluate the prognostic impact of pre-transplant minimal residual disease (MRD) as determined by real-time quantitative polymerase chain reaction in 67 adult NPM1-mutated acute myeloid leukemia patients receiving allogeneic hematopoietic stem cell transplantation (HSCT). Twenty-eight of the 67 patients had a FLT3-ITD (42%). Median age at transplantation was 54.7 years, median follow-up for survival from time of allografting was 4.9 years. At transplantation, 31 patients were in first, 20 in second complete remission (CR) and 16 had refractory disease (RD). Pre-transplant NPM1 MRD levels were measured in 39 CR patients. Overall survival (OS) for patients transplanted in CR was significantly longer as compared to patients with RD (P=0.004), irrespective of whether the patients were transplanted in first or second CR (P=0.74). There was a highly significant difference in OS after allogeneic HSCT between pre-transplant MRD-positive and MRD-negative patients (estimated 5-year OS rates of 40 vs 89%; P=0.007). Multivariable analyses on time to relapse and OS revealed pre-transplant NPM1 MRD levels >1% as an independent prognostic factor for poor survival after allogeneic HSCT, whereas FLT3-ITD had no impact. Notably, outcome of patients with pre-transplant NPM1 MRD positivity >1% was as poor as that of patients transplanted with RD. PMID:27471865

    The risk of acute graft-versus-host disease (aGVHD) can be reliably estimated by the hematopoietic cell transplantation-specific comorbidity index (HCT-CI), which can be further refined by the incorporation of pre-hematopoietic cell transplantation (HCT) serum levels of inflammatory biomarkers such as ferritin and albumin. β2-Microglobulin (β2-m) is a key component of the MHC class I complex, which is independently associated with mortality and frailty in the general population. We took advantage of our institutional protocol that includes measurement of pre-HCT β2-m serum levels in the most patients to investigate whether pre-transplant β2-m levels were associated with the risk of aGVHD. One hundred three consecutive patients submitted to allogeneic HCT, of which 26 developed grades II to IV aGVHD, were included in the analysis. β2-m was significantly associated with age and HCT-CI. Higher levels of β2-m were observed in patients who developed aGVHD (P = .008). In the multivariate Cox regression model, β2-m and HCT-CI remained independently associated with the risk of developing aGVHD. In conclusion, the association between β2-m and the occurrence of aGVHD suggests that the measurement of this protein before HCT might represent an additional element for risk stratification of aGVHD.

    In contrast to the upfront setting in which the role of high-dose therapy with autologous hematopoietic cell transplantation (HCT) as consolidation of a first remission in patients with multiple myeloma (MM) is well established, the role of high-dose therapy with autologous or allogeneic HCT has not been extensively studied in MM patients relapsing after primary therapy. The International Myeloma Working Group together with the Blood and Marrow Transplant Clinical Trials Network, the American Society of Blood and Marrow Transplantation, and the European Society of Blood and Marrow Transplantation convened a meeting of MM experts to: (1) summarize current knowledge regarding the role of autologous or allogeneic HCT in MM patients progressing after primary therapy, (2) propose guidelines for the use of salvage HCT in MM, (3) identify knowledge gaps, (4) propose a research agenda, and (5) develop a collaborative initiative to move the research agenda forward. After reviewing the available data, the expert committee came to the following consensus statement for salvage autologous HCT: (1) In transplantation-eligible patients relapsing after primary therapy that did NOT include an autologous HCT, high-dose therapy with HCT as part of salvage therapy should be considered standard; (2) High-dose therapy and autologous HCT should be considered appropriate therapy for any patients relapsing after primary therapy that includes an autologous HCT with initial remission duration of more than 18 months; (3) High-dose therapy and autologous HCT can be used as a bridging strategy to allogeneic HCT; (4) The role of postsalvage HCT maintenance needs to be explored in the context of well-designed prospective trials that should include new agents, such as monoclonal antibodies, immune-modulating agents, and oral proteasome inhibitors; (5) Autologous HCT consolidation should be explored as a strategy to develop novel conditioning regimens or post-HCT strategies in patients with short

    It has been demonstrated that physical exercise benefits younger patients undergoing allogeneic haematopoietic stem cell transplantation (allo-HSCT). We designed a prospective pilot study investigating whether elderly patients (>60 years) would also be able to participate in such a programme. It consisted of physiotherapist-supervised alternating endurance and resistance workouts on 6 of 7 days a week. Sixteen consecutive patients undergoing allo-HSCT were enrolled into the study. The median age was 64.5 years. Twelve patients participated in the programme until the time of discharge (75%) from the transplant unit. Therefore, the predefined criteria regarding feasibility were met. The reason for drop out was transplantation associated mortality in all patients (n = 4). Adherence was very good with a median of 85% attended training sessions. No adverse events were recorded. The endurance capacity dropped by 7% and lower extremity strength improved by 2% over time. Quality of life decreased during the study period, with global health being significantly worse at the time of discharge. In conclusion, a combined and intensified strength and endurance exercise programme is feasible and safe in a population of elderly patients undergoing allo-HSCT. Further research should focus on exploring effect sizes of such an intervention by conducting randomised controlled trials. PMID:26526286

    The outcome of allogeneic HSCT varies considerably by the disease and remission status at the time of transplantation. Any retrospective or prospective HSCT study that enrolls patients across disease types must account for this heterogeneity; yet, current methods are neither standardized nor validated. We conducted a retrospective study of 1539 patients who underwent transplantation at Dana-Farber Cancer Institute/Brigham and Women's Hospital from 2000 to 2009. Using multivariable models for overall survival, we created a disease risk index. This tool uses readily available information about disease and disease status to categorize patients into 4 risk groups with significantly different overall survival and progression-free survival on the basis of primarily differences in the relapse risk. This scheme applies regardless of conditioning intensity, is independent of comorbidity index, and was validated in an independent cohort of 672 patients from the Fred Hutchinson Cancer Research Center. This simple and validated scheme could be used to risk-stratify patients in both retrospective and prospective HSCT studies, to calibrate HSCT outcomes across studies and centers, and to promote the design of HSCT clinical trials that enroll patients across diseases and disease states, increasing our ability to study nondisease-specific outcomes in HSCT.

    In order to obtain an additional graft versus leukemia effect (GVL) and rapid engraftment, donor leukocyte infusion (DLI) was added to unseparated, sex-mismatched allogeneic bone marrow transplantation in two male patients (age 21, 26) affected by high risk hematological malignancies (refractory T-ALL, refractory B-LBL in leukemic phase). Graft versus host disease (GVHD) prophylaxis consisted of methotrexate (MTX) alone. DLI were obtained after G-CSF 16 ug/kg/day sc. A total of 2.36 and 5.8 x 10(6)/kg MNC, 5.4 and 11 x 10(6)/kg CD34+ cells, 1.3 and 1.3 x 10(6)/kg CD3+ lymphocytes, respectively, were infused. Hemopoietic recovery occurred promptly. Complete chimerism was detected by cytogenetic examination. One patient developed an extramedullary relapse that first involved the cranial nerves, and then the testes, soft tissue and skin; the other patient developed central nervous system disease and then bilateral paravertebral masses with progressive paraplegia. Despite complete medullary remission with normal female karyotype, both patients died from extramedullary progression of their disease. Our observation shows that, at least in high risk patients, no additional GVHD or GVL effect was evident after donor leukocyte infusion. Extramedullary relapse was not prevented despite good control of medullary disease. PMID:8641654

    Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive disorder caused by mutations in the gene encoding thymidine phosphorylase (TP). Allogeneic hematopoietic stem cell transplantation (HSCT) has been proposed as a treatment for patients with MNGIE and a standardized approach to HSCT in this condition has recently been developed. We report on the transplant course, management and short-term follow-up in two MNGIE patients who underwent HSCT. The source of stem cells was bone marrow taken from an HLA 9/10 allele-matched unrelated donor in the first patient and from an HLA 10/10 allele-matched sibling donor in the second. Both patients achieved full donor chimerism, and we observed restoration of buffy coat TP activity and lowered urine nucleoside concentrations in both of them. The post-transplant clinical follow-up showed improvement in gastrointestinal dysmotility, abdominal cramps and diarrhea. Neurological assessment remained unchanged. However, the first patient died 15 months after HSCT due to gastrointestinal obstruction and shock; the second patient died 8 months after the procedure due to respiratory distress following septic shock. Although HSCT corrects biochemical abnormalities and improves gastrointestinal symptoms, the procedure can be risky in subjects already in poor medical condition as are many MNGIE patients. Since transplant-related morbidity and mortality increases with progression of the disease and number of comorbidities, MNGIE patients should be submitted to HSCT when they are still relatively healthy, in order to minimize the complications of the procedure. Anyway, there is still incomplete knowledge on the natural history of the disease in many affected patients and it is not yet clear when the best time to do a transplant is. Further clues to the therapeutic potential of HSCT could result from a prolonged observation in a greater number of non-transplanted and transplanted patients, which would allow us

    We sought to create a population pharmacokinetic model for total mycophenolic acid (MPA), to study the effects of different covariates on MPA pharmacokinetics, to create a limited sampling schedule (LSS) to characterize MPA exposure (i.e., area under the curve or AUC) with maximum a posteriori Bayesian estimation, and to simulate an optimized dosing scheme for allogeneic hematopoietic cell transplantation (HCT) recipients. 4,496 MPA concentration-time points from 408 HCT recipients were analyzed retrospectively using a nonlinear mixed effects modeling approach. MPA pharmacokinetics was characterized with a two-compartment model with first-order elimination and a time-lagged first-order absorption process. Concomitant cyclosporine and serum albumin were significant covariates. The median MPA clearance and volume of the central compartment were 24.2 L/hr and 36.4 L, respectively, for a 70 kg patient receiving tacrolimus with a serum albumin of 3.4 g/dL. Dosing simulations indicated that higher oral MMF doses are needed with concomitant cyclosporine, which increases MPA clearance by 33.8%. The optimal LSS was immediately before and at 0.25, 1.25, 2, and 4hr after oral MMF administration. MPA AUC in an individual HCT recipient can be accurately estimated using a five-sample LSS and maximum a posteriori Bayesian estimation. PMID:23382105

    Allogeneic hematopoietic SCT (HSCT) has been proposed as a treatment for patients with mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). HSCT has been performed in nine patients using different protocols with varying success. Based on this preliminary experience, participants of the first consensus conference propose a common approach to allogeneic HSCT in MNGIE. Standardization of the transplant protocol and the clinical and biochemical assessments will allow evaluation of the safety and efficacy of HSCT as well as optimization of therapy for patients with MNGIE.

    Allogeneic hematopoietic cell transplantation (HCT) offers the chance of cure for patients with non-transformed follicular lymphoma (FL), but is associated with the risk of non-relapse mortality (NRM). The aim of this study was to identify subgroups of FL patients who benefit from HCT. The European Society for Blood and Marrow Transplantation (EBMT) Minimum-Essential-A Data of 146 consecutive patients who received HCT for FL between 1998 and 2008 were extracted from the database of the German Registry 'DRST'. Diagnosis of FL was verified by contact with the reference pathologists. Estimated 1-, 2- and 5-year overall survivals (OS) were 67%, 60% and 53%, respectively. Day 100 NRM was 15%. Thirteen out of 33 patients (40%) with treatment-refractory disease (RD) at the time of transplantation survived long term. Univariate statistical analysis suggested limited chronic GvHD, donor age ⩽42 years and TBI-based conditioning in treatment refractory patients to correlate with favorable OS. Independent prognostic factors for OS were treatment-sensitive disease and limited chronic GvHD for the whole cohort, and additionally TBI-based conditioning for the treatment refractory subgroup. In contrast, patient age ⩾55 years had no impact on outcome. Thus, HCT for FL is associated with acceptable NRM, and offers a substantial chance of cure for patients with RD or advanced age. Donors ⩽42 years should be preferred if available. PMID:26855152

    Hematopoietic cell transplantation (HCT) offers potentially curative therapy for chronic myelomonocytic leukemia (CMML). We evaluated HCT outcomes in 85 patients with CMML, 1.0-69.1 (median 51.7) years of age, with follow-up extending to 19 years. CMML was considered de novo in 71 and secondary in 14 patients. Conditioning regimens were of various intensities. Thirty-eight patients had related (34 HLA identical), and 47 (39 HLA matched) unrelated donors. The source of stem cells was marrow in 32 and peripheral blood progenitor cells in 53 patients. Acute graft-versus-host disease (aGVHD) grades II-IV occurred in 72% and chronic GVHD (cGVHD) in 26% of patients. Relapse incidence was 27% at 10 years. Relapse correlated with increasing scores by the MD Anderson prognostic score (P = .01). The major causes of death were relapse and infections ±GVHD. Progression-free survival (PFS) was 38% at 10 years. Mortality was negatively correlated with pre-HCT hematocrit (P = .007), and increased with high-risk cytogenetics (P = .02), higher HCT Comorbidity Index (P = .0008), and increased age (P = .02). WHO classification did not statistically significantly affect outcome. Thus, a proportion of patients with CMML have lasting remissions following allogeneic HCT and appear to be cured of their disease. PMID:20932924

    Intestinal dysbiosis has been associated with acute gastrointestinal GvHD and poor outcome following allogeneic stem cell transplantation (ASCT). To assess the effect of a switch in 2012 from ciprofloxacin/metronidazole to rifaximin for gut decontamination on intestinal microbiota composition and ASCT outcome, we retrospectively analyzed 394 patients receiving ASCT from September 2008 through June 2015. In 131 and 90 patients, respectively, urinary 3-indoxyl sulfate levels and intestinal enterococcal load were measured before conditioning and weekly within the first 28 days after ASCT. The use of rifaximin correlated with lower enterococcal positivity (6.9 vs 21.9%, P=0.05) and higher urinary 3-indoxyl sulfate concentrations (10.5 vs 4.6 μmoL/mmoL crea, P<0.001) after ASCT. Patients on rifaximin showed lower 1-year transplant-related mortality (P=0.04) and higher overall survival (P=0.008). Treatment of infectious complications with systemic antibiotics did not abrogate the beneficial effects of rifaximin on intestinal microbiota composition in the early course of ASCT and outcome. The data underscore the importance of maintaining a diverse population of symbiotic and mutualistic bacteria in the gut on ASCT outcome. PMID:26999466

    The outcome of children, adolescents and young adults (CAYA) with poor-risk recurrent/refractory lymphoma is dismal (⩽30%). To overcome this poor prognosis, we designed an approach to maximize an allogeneic graft vs lymphoma effect in the setting of low disease burden. We conducted a multi-center prospective study of myeloablative conditioning (MAC) and autologous stem cell transplantation (AutoSCT), followed by a reduced intensity conditioning (RIC) and allogeneic hematopoietic cell transplantation (AlloHCT) in CAYA, with poor-risk refractory or recurrent lymphoma. Conditioning for MAC AutoSCT consisted of carmustine/etoposide/cyclophosphamide, RIC consisted of busulfan/fludarabine. Thirty patients, 16 Hodgkin lymphoma (HL) and 14 non-Hodgkin lymphoma (NHL), with a median age of 16 years and median follow-up of 5years, were enrolled. Twenty-three patients completed both MAC AutoSCT and RIC AlloHCT. Allogeneic donor sources included unrelated cord blood (n=9), unrelated donor (n=8) and matched siblings (n=6). The incidence of transplant-related mortality following RIC AlloHCT was only 12%. In patients with HL and NHL, 10 year EFS was 59.8% and 70% (P=0.613), respectively. In summary, this approach is safe, and long-term EFS with this approach is encouraging considering the poor-risk patient characteristics and the use of unrelated donors for RIC AlloHCT in the majority of cases.

    Oral mucositis (OM) is a debilitating early adverse effect of allogeneic hematopoietic stem cell transplantation (HSCT). The intensity of the conditioning regimen correlates with the incidence and severity of OM, but no studies have analyzed this relationship among various conditioning regimens. We performed a systematic review on the incidence and outcomes of OM in allogeneic HSCT patients and analyzed this association. A comprehensive search of several databases (Ovid Medline In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Cochrane CRCT, Cochrane DSR, Scopus) from 1990 to 2014 for studies of OM in allogeneic HSCT patients was conducted. Professional societies' meeting abstracts were also searched. Grade of OM was analyzed based on the World Health Organization (WHO) or National Cancer Institutes (NCI) Common Terminology Criteria for Adverse Events scales. Severe mucositis was defined as either grades 2 to 4 or grades 3 and 4, depending on the studies' definition of severity. Cohorts were analyzed based on regimen intensity; ie, reduced-intensity conditioning (RIC) (including nonmyeloablative) and myeloablative (MA). Random effect (RE) and standard logistic models weighted by the number of patients in each cohort were used for comparisons. A total of 624 studies were generated from the search. Of the 395 patients in 8 eligible MA regimen studies, 73.2% experienced any OM, whereas in 245 patients in the 6 eligible RIC regimen studies, 86.5% experienced any OM (chi-square P < .0001; RE, P = .05). Severe (grades 2 to 4) OM occurred among 79.7% of the WHO/NCI-graded MA patients and 71.5% of RIC patients (chi-square, P = .0421; RE, P < .01). In comparing graft-versus-host disease (GVHD) prophylaxis, only 55.4% of patients receiving nonmethotrexate regimens experienced OM; this was lower (chi-square, P < .0001; RE, P = .06) than that found among patients who received methotrexate (83.4%), either standard or reduced dose.

    Allogeneic hematopoietic cell transplantation (alloHCT) with reduced-intensity conditioning is an appealing option for patients with high-risk multiple myeloma (MM). However, progression after alloHCT remains a challenge. Maintenance therapy after alloHCT may offer additional disease control and allow time for a graft-versus-myeloma effect. The primary objective of this clinical trial was to determine the tolerability and safety profile of maintenance lenalidomide (LEN) given on days 1 to 21 of 28 days cycles, with intrapatient dose escalation during 12 months/cycles after alloHCT. Thirty alloHCT recipients (median age, 54 years) with high-risk MM were enrolled at 8 centers between 2009 and 2012. The median time from alloHCT to LEN initiation was 96 days (range, 66 to 171 days). Eleven patients (37%) completed maintenance and 10 mg daily was the most commonly delivered dose (44%). Most common reasons for discontinuation were acute graft-versus-host disease (GVHD) (37%) and disease progression (37%). Cumulative incidence of grades III to IV acute GVHD from time of initiation of LEN was 17%. Outcomes at 18 months after initiation of maintenance were MM progression, 28%; transplantation-related mortality, 11%; and progression-free and overall survival, 63% and 78%, respectively. The use of LEN after alloHCT is feasible at lower doses, although it is associated with a 38% incidence of acute GVHD. Survival outcomes observed in this high-risk MM population warrant further study of this approach. PMID:24769014

    Regionalization of specialized health services can deliver high-quality care but may have an adverse impact on access and outcomes because of distance from the regional centers. In the case of hematopoietic cell transplantation (HCT), the effect of increased distance between the transplantation center and the rural/urban residence is unclear because of conflicting results from the existing studies. We examined the association between distance from primary residence to the transplantation center and rural versus urban residence with clinical outcomes after allogeneic HCT in a large cohort of patients. Overall mortality (OM), nonrelapse mortality (NRM), and relapse in all patients and those who survived for 200 days after HCT were assessed in 2849 patients who received their first allogeneic HCT between 2000 and 2010 at Fred Hutchinson Cancer Research Center (FHCRC)/Seattle Cancer Care Alliance. Median distance from FHCRC was 263 miles (range, 0 to 2740 miles) and 83% of patients were urban residents. The association between distance and the hazard of OM varied according to conditioning intensity: myeloablative (MA) versus nonmyeloablative (NMA). Among MA patients, there was no evidence of an increased risk of mortality with increased distance, but for NMA patients, the results did show a suggestion of increased risk of mortality for some distances, although globally the difference was not statistically significant. In the subgroup of patients who survived 200 days, there was no evidence that the risks of OM, relapse, or NRM were increased with increasing distance. We did not find any association between longer distance from transplantation center and urban/rural residence and outcomes after MA HCT. In patients undergoing NMA transplantations, this relationship and how it is influenced by factors such as age, payers, and comorbidities needs to be further investigated. PMID:27013013

    Clostridium difficile infections (CDI) remain the leading cause of infectious diarrhea among hospitalized patients in this country. Patients with hematologic malignancies, especially those who undergo hematopoietic progenitor cell transplants are particularly at risk for developing CDI. One hundred and forty seven consecutive allogeneic hematopoietic progenitor cell transplants were analyzed for peri-transplant Clostridium difficile infections (PT-CDI). Sixteen patients (11%) developed PT-CDI (Median time = 7 days after transplant). The probability for developing PT-CDI during the peri-transplant period was 12.3%. History of CDI was strongly associated with the development of PT-CDI (P = 0.008) (OR = 5.48) (P = 0.017). These patients also developed PT-CDI much earlier than in those without a history (median 1 day vs. 8 days, P = 0.03). The probability for developing PT-CDI for those with a history was 39%. There was a trend toward significance (P = 0.065) between matched related donor grafts and the development of PT-CDI (OR = 0.245) (P = 0.08). Age, sex, diagnosis, transplant preparative regimens, Graft-versus-host disease (GVHD) prophylaxis, grade 3/4 acute GVHD, or use of antimicrobials within 8 weeks of transplant were not associated with PT-CDI. Non-CDI-related deaths occurred in one patient in the PT-CDI group and nine in the group without PT-CDI. In the remaining 139 patients, the length of hospital stay for those with PT-CDI was significantly longer than those without (mean 27 days vs. 22 days; P = 0.02). PMID:26661725

    Patients undergoing haematopoietic stem cell transplantation (HSCT) are at high risk of severe gastrointestinal bleeding caused by infections, graft versus host disease, and disturbances in haemostasis. BK polyomavirus (BKPyV) is known to cause hemorrhagic cystitis, but there is also evidence of BKV shedding in stool and its association with gastrointestinal disease. We report putative association of BKPyV replication with high plasma viral loads in a pediatric HSCT patient developing hemorrhagic cystitis and severe gastrointestinal bleeding necessitating intensive care. The observation was based on chart review and analysis of BKPyV DNA loads in plasma and urine as well as retrospective BKPyV-specific IgM and IgG measurements in weekly samples until three months post-transplant. The gastrointestinal bleeding was observed after a >100-fold increase in the plasma BKPyV loads and the start of hemorrhagic cystitis. The BKPyV-specific antibody response indicated past infection prior to transplantation, but increasing IgG titers were seen following BKPyV replication. The gastrointestinal biopsies were taken at a late stage of the episode and were no longer informative of BK polyomavirus involvement. In conclusion, gastrointestinal complications with bleeding are a significant problem after allogeneic HSCT to which viral infections including BKPyV may contribute. PMID:25542476

    Candida lipolytica was recovered from the blood and the central venous catheter in a patient receiving allogeneic bone marrow transplantation. Two C. lipolytica strains from different geographical areas and the ATCC 9773 strain of C. lipolytica were used as controls. C. lipolytica was identified by standard methods. MICs indicated antifungal susceptibilities to amphotericin B, fluconazole, and itraconazole for all strains. In vitro testing and scanning electron microscopy showed that C. lipolytica was capable of producing large amounts of viscid slime material in glucose-containing solution, likely responsible for the ability of the yeast to adhere to catheter surfaces. Restriction fragment length polymorphisms revealed an identical profile for all clinical isolates, unrelated to those observed for the control strains. This finding suggested the absence of microevolutionary changes in the population of the infecting strain, despite the length of the sepsis and the potential selective pressure of amphotericin B, which had been administered to the patient for about 20 days. The genomic differences that emerged between the isolates and the control strains were indicative of a certain degree of genetic diversity between C. lipolytica isolates from different geographical areas.

    Allogeneic hematopoietic cell transplantation (alloHCT) extends the lives of thousands of patients who would otherwise succumb to hematopoietic malignancies such as leukemias and lymphomas, aplastic anemia, and disorders of the immune system. In alloHCT, different immune cell types mediate beneficial graft-versus-tumor (GvT) effects, regulate detrimental graft-versus-host disease (GvHD), and are required for protection against infections. Today, the “good” (GvT effector cells and memory cells conferring protection) cannot be easily separated from the “bad” (GvHD-causing cells), and alloHCT remains a hazardous medical modality. The transplantation of hematopoietic stem cells into an immunosuppressed patient creates a delicate environment for the reconstitution of donor blood and immune cells in co-existence with host cells. Immunological reconstitution determines to a large extent the immune status of the allo-transplanted host against infections and the recurrence of cancer, and is critical for long-term protection and survival after clinical alloHCT. Animal models continue to be extremely valuable experimental tools that widen our understanding of, for example, the dynamics of post-transplant hematopoiesis and the complexity of immune reconstitution with multiple ways of interaction between host and donor cells. In this review, we discuss the rat as an experimental model of HCT between allogeneic individuals. We summarize our findings on lymphocyte reconstitution in transplanted rats and illustrate the disease pathology of this particular model. We also introduce the rat skin explant assay, a feasible alternative to in vivo transplantation studies. The skin explant assay can be used to elucidate the biology of graft-versus-host reactions, which are known to have a major impact on immune reconstitution, and to perform genome-wide gene expression studies using controlled combinations of minor and major histocompatibility between the donor and the recipient

    We describe outcomes after allogeneic hematopoietic cell transplantation (HCT) for mycosis fungoides and Sezary syndrome (MF/SS). Outcomes of 129 subjects with MF/SS reported to the Center for the International Blood and Marrow Transplant from 2000-2009. Median time from diagnosis to transplant was 30 (4-206) months and most subjects were with multiply relapsed/ refractory disease. The majority (64%) received non-myeloablative conditioning (NST) or reduced intensity conditioning (RIC). NST/RIC recipients were older in age compared with myeloablative recipients (median age 51 vs 44 years, P=0.005) and transplanted in recent years. Non-relapse mortality (NRM) at 1 and 5 years was 19% (95% confidence interval (CI) 12-27%) and 22% (95% CI 15-31%), respectively. Risk of disease progression was 50% (95% CI 41-60%) at 1 year and 61% (95% CI 50-71%) at 5 years. PFS at 1 and 5 years was 31% (95% CI 22-40%) and 17% (95% CI 9-26%), respectively. OS at 1 and 5 years was 54% (95% CI 45-63%) and 32% (95% CI 22-44%), respectively. Allogeneic HCT in MF/SS results in 5-year survival in approximately one-third of patients and of those, half remain disease-free. PMID:25068422

    Background Invasive fungal infections (IFIs) are chief infectious complications in patients undergoing hematopoietic stem cell transplantation (HSCT). However, the diagnosis of fungal infections is difficult, and often empiric treatment initiates. Since there is no data available on the prevalence of antifungal drugs administration in allogeneic HSCT recipients in Iran, we decided to conduct this study. Methods This study was a retrospective review of records of patients who received allogeneic HSCT in the Hematology-Oncology, Bone Marrow Transplantation center at Shariati Hospital in Tehran, between August 2009 and August 2010. Results Sixty (73.1%) patients consist of 41 men (68.3%) with mean age of 26.3 (± 1.2) years received allogeneic HSCT. Patients received prophylaxis with fulconazole however; in 28 patients (46.7%) it was switched to low dose amphotericin B. Fifteen patients (25%) received treatment with antifungal agents. Amphotericin B was the empiric agent administered. In 3 patients treatment was switched to voriconazole. Neither positive culture nor direct microscopic evidence was available from the obtained specimen. Only in one patient the result of serum galactomannan assay was positive. There were no significant differences in neutropenia duration (P value: 0.54), length of hospital stay (P value: 0.27) and number of patients developed graft versus host disease (P value: 0.07) between patients received antifungal agents with those who did not receive treatment. Conclusion In this study HSCT recipients received antifungal agents for prophylaxis. Twenty five percent of patients received treatment with antifungal agents empirically. Improvement in diagnosis of these infections can be helpful and lead to targeted therapy. We suggest larger prospective trials for better assessment of antifungal agent administration. PMID:24505528

    To analyze the influence of distinct combinations of molecular aberrations on outcome after allogeneic hematopoietic stem cell transplantation (HSCT) for cytogenetically normal acute myeloid leukemia (CN-AML), a retrospective registry analysis was performed on 702 adults undergoing HSCT in first complete remission (CR). Patients were grouped according to presence or absence of NPM1 mutations (NPM1(mut)) and FLT3 internal tandem duplications (FLT3-ITD). Double-negative patients were evaluated for mutations of the CCAAT/enhancer binding protein α gene (CEBPα). The influence of genotypes on relapse, non-relapse mortality, leukemia-free survival (LFS) and overall survival (OS), and a prognostic classification combining NPM1/FLT3-ITD profile and classical risk factors were calculated. Two-year OS from HSCT was 81 ± 5% in NPM1(mut)/FLT3(wt), 75 ± 3% in NPM1(wt)/FLT3(wt), 66 ± 3% in NPM1(mut)/FLT3-ITD, and 54 ± 7% in NPM1(wt)/FLT3-ITD (P = .003). Analysis of CEBPα among patients with NPM1(wt)/FLT3(wt) revealed excellent results both in patients with CEBPα(mut) and with a triple negative genotype (2-year OS: 100%/77 ± 3%). In a Cox-model of predefined variables, age, FLT3-ITD and >1 course of chemotherapy to reach CR were risk factors associated with inferior outcome, regardless of NPM1 mutational status, variations of transplant protocols, or development of graft-versus-host disease. In a prognostic risk classification, 2-year OS/LFS rates were 88 ± 3%/79 ± 4% without any, 77 ± 2%/73 ± 3% with one, and 53 ± 4%/50 ± 4 with ≥2 risk factors (P = .003/.002). PMID:26351297

    Myeloablative allogeneic hematopoietic cell transplantation (HCT) may cure patients with relapsed or refractory Hodgkin Lymphoma (HL), but is associated with a high treatment-related mortality (TRM). Reduced intensity and nonmyeloablative (RIC/NST) conditioning regimens aim to lower TRM. We analyzed the outcomes of 143 patients undergoing unrelated donor RIC/NST HCT for relapsed and refractory HL between 1999 and 2004 reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). Patients were heavily pretreated, including autologous HCT in 89%. With a median follow-up of 25 months, the probability of TRM at day 100 and 2 years was 15% (95% CI 10-21%) and 33% (95% CI 25-41%) respectively. The probabilities of progression free survival (PFS) and overall survival (OS) were 30% and 56% at 1 year and 20% and 37% at 2 years. The presence of extranodal disease and KPS < 90 were significant risk factors for TRM, PFS and OS, whereas chemosensitivity at transplantation was not. Dose intensity of the conditioning regimen (RIC vs NST) did not impact outcomes. Unrelated donor HCT with RIC/NST can salvage some patients with relapsed/refractory HL, but relapse remains a common reason for treatment failure. Clinical studies should be aimed at reducing the incidence of acute Graft-versus-Host Disease and relapse. PMID:19135949

    Early relapsed or refractory follicular lymphoma (FL) warrants consolidation with transplantation, though graft source modality remains controversial. We analysed the outcomes of 44 patients transplanted with either autologous or allogeneic graft sources in the post-rituximab era. No difference in event-free (EFS) or overall survival (OS) was observed between allogeneic (81% and 81%) and autologous transplantation (64% and 70%) at 3 years. There was a significant difference in EFS between allogeneic and autologous transplantation patients with previous remission duration of ≤12 months (80% and 42% at 3 years, P < 0·015). Very early relapsed FL may warrant consideration of allogeneic over autologous transplantation in the appropriate setting. PMID:26847389

    Intensive chemotherapy or chemotherapy plus irradiation and allogeneic stem cell transplantation can be curative for patients with hematologic diseases. Reduced-intensity transplants can also achieve cure and result in less treatment-related mortality but higher relapse rates. Thus, optimizing the conditioning regimens used in allogeneic transplantation remains an important goal. We conducted a phase I/II trial to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of a continuous infusion of busulfan over 90 hours in conjunction with fludarabine followed by allogeneic related or unrelated donor transplant. Fifty-four patients with advanced hematologic malignancies were enrolled on this study. The MTD was identified as a 24-hour area under the curve (AUC) of approximately 7095 μM/min, which represents a 43% increase over the standard total daily AUC dose of 4800 μM/min given by intermittent schedules. DLTs at doses over 8000 μM/min were identified by a desquamative skin rash and mucositis. No dose-related increase in hepatic, pulmonary, or other organ toxicities were seen, whereas efficacy appeared to be improved at higher dose levels. Continuous-infusion busulfan with intermittent fludarabine provides an alternative treatment strategy that is generally well tolerated and permits an increase in total busulfan dose with encouraging efficacy.

    Relapse is least common in patients with indolent B cell (iB) malignancies (ie, iB non-Hodgkin lymphoma [NHL]) who undergo nonmyeloablative allogeneic transplantation (NMAT) in complete remission (CR). However, for the many patients unable to achieve this state, outcomes are poorly described and methods to improve results are unknown. We sought to describe the long-term follow-up and predictive factors for these poor-risk patients unable to achieve CR before NMAT. We identified and evaluated patients with iB-NHL including chronic lymphocytic leukemia treated with fludarabine/total body irradiation-based NMAT that had evidence of persistent disease before NMAT. From December 1998 to April 2009, 89 patients were identified, most commonly with small/chronic lymphocytic lymphoma (n = 62) and follicular lymphoma (n = 24). Pretransplant anti-CD20 radioimmunotherapy (RIT) using standard yttrium-90-ibritumomab tiuxetan was administered to 18 patients (20%) who more frequently had chemoresistant disease (81% versus 39%, P = .003), disease bulk > 5 cm (61% versus 15%, P < .001), thrombocytopenia < 25k/μL (33% versus 7%, P = .002), and Hematopoietic Cell Transplant Comorbidity Index scores ≥ 3 (72% versus 37%, P = .006). After adjusting for these imbalances, RIT-treated patients had improved rates of progression-free survival (PFS) (hazard ratio [HR] = .4; 95% confidence interval [CI], .2 to .9, P = .02) and overall survival (OS) (HR = .3; 95% CI, .1 to .8, P = .008) compared with the non-RIT group. The 3-year adjusted estimates of PFS and OS for the RIT and non-RIT groups were 71% and 87% versus 44% and 59%, respectively. The use of RIT was the only factor independently associated with improved PFS and OS. Rates of nonrelapse mortality and graft-versus-host disease (GVHD) were similar between the 2 groups, although over 70% of patients developed clinically significant acute or chronic GVHD. In conclusion, despite relatively high rates of GVHD, patients with persistent i

    Intracranial hemorrhage (ICH) is one of the most life-threatening neurological complications after allogeneic hematopoietic stem cell transplantation. Although cerebral complications and its causes after allo-HSCT are well documented, assessment of the incidence and risk factors of intracranial hemorrhage following allo-HSCT are less discussed. A nested case-control study was conducted involving 160 subjects drawn from 2169 subjects who underwent HSCT at Peking University People's Hospital between 2004 and 2014. Thirty-two patients (1.5 %) with ICH were identified, and 128 controls were matched for age, gender, transplantation type, and time of transplantation. Intracranial hemorrhage was identified by CT scan and/or MRI by searching hospital records. Among the 32 ICH patients, 27 (82.9 %) developed intraparenchymal hemorrhages (IPH), 2 cases (5.7 %) suffered subdural hematomas (SDH), and 3 cases (8.6 %) had multiple hemorrhage lesions in the brain parenchyma. The median time of appearance for cerebral hemorrhages was 147.5 days. Multivariate analysis showed that systemic infections (hazard ratio 2.882, 95 % confidence interval 1.231-6.746), platelet count (5.894, 1.145-30.339), and fibrinogen levels (3.611, 1.528-8.532) were independent risk factors for intracranial hemorrhage among HSCT patients. The cumulative survival rate in the intracranial hemorrhage and control groups were 43.3 and 74.7 % (P = .001), respectively. Intracranial hemorrhage is associated with high mortality and a decreased overall survival rate. Systemic infections, platelet count, and fibrinogen levels were individual independent risk factors.

    As older patients are eligible for allogeneic hematopoietic cell transplantation (HCT), older siblings are increasingly proposed as donors. We studied the impact of donor age on the tempo of hematopoietic engraftment and donor chimerism, acute and chronic graft-versus-host disease (GVHD), and nonrelapse mortality (NRM) among 1174 consecutive patients undergoing myeloablative and 367 patients undergoing nonmyeloablative HCT from HLA-matched related or unrelated donors with granulocyte colony-stimulating factor-mobilized peripheral blood mononuclear cell allografts. Sustained engraftment rates were 97% and 98% in patients undergoing myeloablative and nonmyeloablative conditioning, respectively, for grafts from donors < 60 years old (younger; n = 1416) and 98% and 100%, respectively, for those from donors ≥ 60 years old (older; n = 125). No significant differences were seen in the tempo of neutrophil and platelet recoveries and donor chimerism except for an average 1.3-day delay in neutrophil recovery among myeloablative patients with older donors (P = .04). CD34(+) cell dose had an independent effect on the tempo of engraftment. Aged stem cells did not convey an increased risk of donor-derived clonal disorders after HCT. Myeloablative and nonmyeloablative recipients with older sibling donors had significantly less grade II to IV acute GVHD than recipients with grafts from younger unrelated donors. Rates of grade III and IV acute GVHD, chronic GVHD, and NRM for recipients with older donors were not significantly different from recipients with younger donors. In conclusion, grafts from donors ≥ 60 years old do not adversely affect outcomes of allogeneic HCT compared with grafts from younger donors. PMID:25278458

    AIM: To investigate the timing, safety and efficacy of prophylactic antiviral therapy in patients with hepatitis B virus (HBV) infection undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: This prospective study recruited a total of 57 patients diagnosed with malignant hematological diseases and HBV infection at the First Affiliated Hospital of Sun Yat-sen University between 2006 and 2013. The patients were classified as hepatitis B surface antigen (HBsAg)-positive or HBsAg-negative/ antiHBc-positive. Patients were treated with chemotherapy followed by antiviral therapy with nucleoside analogues. Patients underwent allo-HSCT when serum HBV DNA was < 103 IU/mL. Following allo-HSCT, antiviral therapy was continued for 1 year after the discontinuation of immunosuppressive therapy. A total of 105 patients who underwent allo-HSCT and had no HBV infection were recruited as controls. The three groups were compared for incidence of graft-vs-host disease (GVHD), drug-induced liver injury, hepatic veno-occlusive disease, death and survival time. RESULTS: A total of 29 of the 41 subjects with chronic GVHD exhibited extensive involvement and 12 exhibited focal involvement. Ten of the 13 subjects with chronic GVHD in the HBsAg(-)/hepatitis B core antibody(+) group exhibited extensive involvement and 3 exhibited focal involvement. Five of the 10 subjects with chronic GVHD in the HBsAg(+) group exhibited extensive involvement and 5 exhibited focal involvement. The non HBV-infected group did not differ significantly from the HBsAg-negative/antiHBc-positive and the HBsAg-positive groups which were treated with nucleoside analogues in the incidence of graft-vs-host disease (acute GVHD; 37.1%, 46.9% and 40%, respectively; P = 0.614; chronic GVHD; 39%, 40.6% and 40%, respectively; P = 0.98), drug-induced liver injury (25.7%, 18.7% and 28%, respectively; P = 0.7), death (37.1%, 40.6% and 52%, respectively; P = 0.4) and survival times (P = 0.516).

    Adolescents and young adults (AYAs, ages 15 to 40 years) with cancer have not experienced survival improvements to the same extent as younger and older patients. We compared changes in survival after myeloablative allogeneic hematopoietic cell transplantation (HCT) for acute lymphoblastic leukemia (ALL) among children (n = 981), AYAs (n = 1218), and older adults (n = 469) who underwent transplantation over 3 time periods: 1990 to 1995, 1996 to 2001, and 2002 to 2007. Five-year survival varied inversely with age group. Survival improved over time in AYAs and paralleled that seen in children; however, overall survival did not change over time for older adults. Survival improvements were primarily related to lower rates of early treatment-related mortality in the most recent era. For all cohorts, relapse rates did not change over time. A subset of 222 AYAs between the ages of 15 and 25 at 46 pediatric or 49 adult centers were also analyzed to describe differences by center type. In this subgroup, there were differences in transplantation practices among pediatric and adult centers, although HCT outcomes did not differ by center type. Survival for AYAs undergoing myeloablative allogeneic HCT for ALL improved at a similar rate as survival for children. PMID:24607554

    To compare the clinical outcomes of older (age ≥ 55 years) non-Hodgkin’s lymphoma (NHL) patients with younger NHL patients (< 55 years) receiving autologous hematopoietic cell transplantation (HCT) while adjusting for patient-, disease-, and treatment-related variables. We compared autologous HCT outcomes in 805 NHL patients age ≥ 55 years to 1,949 NHL patients < 55 years during the years 1990–2000 using data reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). In multivariate analysis, older patients with aggressive histologies were 1.86 times [95% confidence interval (CI) 1.43–2.43, p<0.001] more likely than younger patients to experience treatment-related mortality. Relative death risks were 1.33 times (CI 1.04–1.71, p=0.024) and 1.50 times (CI 1.33–169, p<0.001) higher in older compared to younger patients with follicular grade I/II and aggressive histologies, respectively. Autologous HCT in older NHL patients is feasible but most disease-related outcomes are statistically inferior to younger patients. Studies addressing supportive care particular to older patients who are most likely to benefit from this approach are recommended. PMID:19041053

    There is some preliminary evidence, that veno-occlusive disease prophylaxis with defibrotide (DF) may also have a role in decreasing risk of acute graft-versus-host disease (aGvHD) by preventing tissue damage. In this study, we aimed to investigate the role of DF prophylaxis on the development of aGvHD at D + 180. One hundred ninety-five consecutive adult patients receiving allogeneic HCT were retrospectively evaluated in 3 groups: no DF, DF/post-HCT (DF D + 1 to D + 14) and DF/pre-HCT (DF for 14 days concurrently with conditioning). The total (p: 0.057) and grades III/IV (p: 0.051) aGvHD rates at D + 180 were 46.5%, 40%, 25.5% and 15.5%, 11.2%, 0% in patients on no DF, DF/post-HCT and DF/pre-HCT. DF may have a role in decreasing incidence and severity of aGvHD, especially if used concurrently with conditioning regimen. PMID:26922995

    Purpose Transplantation-related mortality (TRM) is a major barrier to the success of allogeneic hematopoietic cell transplantation (HCT). Patients and Methods We assessed changes in the incidence of TRM and overall survival from 1985 through 2004 in 5,972 patients younger than age 50 years who received myeloablative conditioning and HCT for acute myeloid leukemia (AML) in first complete remission (CR1) or second complete remission (CR2). Results Among HLA-matched sibling donor transplantation recipients, the relative risks (RRs) for TRM were 0.5 and 0.3 for 2000 to 2004 compared with those for 1985 to 1989 in patients in CR1 and CR2, respectively (P < .001). The RRs for all causes of mortality in the latter period were 0.73 (P = .001) and 0.60 (P = .005) for the CR1 and CR2 groups, respectively. Among unrelated donor transplantation recipients, the RRs for TRM were 0.73 (P = .095) and 0.58 (P < .001) for 2000 to 2004 compared with those in 1990 to 1994 in the CR1 and CR2 groups, respectively. Reductions in mortality were observed in the CR2 group (RR, 0.74; P = .03) but not in the CR1 group. Conclusion Our results suggest that innovations in transplantation care since the 1980s and 1990s have reduced the risk of TRM in patients undergoing allogeneic HCT for AML and that this reduction has been accompanied by improvements in overall survival.

    Mucopolysaccharidosis IVA (MPS IVA) is one of the lysosomal storage diseases. It is caused by the deficiency of N-acetylgalactosamine-6-sulfate sulfatase. Deficiency of this enzyme leads to accumulation of the specific glycosaminoglycans keratan sulfate and chondroitin-6-sulfate. This accumulation has a direct impact on cartilage and bone development, resulting in systemic skeletal dysplasia. There is no curative therapy for this skeletal dysplasia. This report describes long-term therapeutic efficacy in a 15-year-old boy with a severe form of MPS IVA who received successful allogeneic bone marrow transplantation (BMT) from his HLA-identical carrier sister. The level of the GALNS enzyme in the recipient’s lymphocytes reached almost half of normal level within two years after BMT. For the successive 9+ years post-BMT, GALNS activity in his lymphocytes maintained the same level as the donor’s, and the level of urinary uronic acid was reduced. Lumbar bone mineral density increased around 50% one year later post-BMT and was kept consistent. Radiographs showed that the figures of trochanter major and minor appeared, while the epiphyseal dysplasia in the femoral cap was almost unchanged. Loud snoring and apnea disappeared. Vital capacity increased to around 20% for the first two years and was maintained. Activity of daily life (ADL) was improved in work/study efficacy, respiratory status, sleep, joint pain, and frequency of infection. In conclusion, the long-term study of hematopoetic stem cell transplantation has shown clinical improvements in respiratory function, radiograph findings, ADL, and biochemical findings, suggesting that it is a potential therapeutic option for patients with MPS IVA.

    The poor prognosis of patients with prolymphocytic leukemia (PLL) has led some clinicians to recommend allogeneic hematopoietic cell transplant (HCT). However, the data to support this approach is limited to case-reports and small case-series. We reviewed the database of the Center for International Blood & Marrow Transplant Research to determine outcomes after allotransplant for patients with PLL. We identified 47 patients with a median age of 54 years (range, 30–75). With a median follow-up of 13 months, progression-free survival was 33% (95% Confidence Interval 20–47%) at 2 years. The most common cause of death was relapse or progression in 49%. The cumulative incidence of treatment-related mortality at 1-year post transplant was 28%. The small patient population prohibited prognostic factor analysis but these data support consideration of allotransplant for PLL. Further study of a larger population of patients is needed to determine which patients are more likely to benefit. PMID:19961946

    Assessment with (18)F-fluorodeoxy glucose (FDG)-positron emission tomography (PET) before hematopoietic cell transplantation (HCT) for lymphoma may be prognostic for outcomes. Patients with chemotherapy-sensitive non-Hodgkin lymphoma (NHL) undergoing allogeneic HCT reported to the Center of International Blood and Marrow Transplantation Registry between 2007 and 2012 were included. Pre-HCT PET status (positive versus negative) was determined by the reporting transplantation centers. We analyzed 336 patients; median age was 55 years and 60% were males. Follicular lymphoma (n = 104) was more common than large cell (n = 85), mantle cell (n = 69), and mature natural killer or T cell lymphoma (n = 78); two thirds of the cohort received reduced-intensity conditioning; one half had unrelated donor grafts. Patients underwent PET scanning a median of 1 month (range, .07 to 2.83 months) before HCT; 159 were PET positive and 177 were PET negative. At 3 years, relapse/progression, progression-free survival (PFS), and overall survival (OS) in PET-positive versus PET-negative groups were 40% versus 26%; P = .007; 43% versus 47%; P = .47; and 58% versus 60%; P = .73, respectively. On multivariate analysis, a positive pretransplantation PET was associated with an increased risk of relapse/progression (risk ratio [RR], 1.86; P = .001) but was not associated with increased mortality (RR, 1.29, 95% confidence interval [CI], .96 to 1.7; P = .08), therapy failure (RR, 1.32; 95% CI, .95 to 1.84; P = .10), or nonrelapse mortality (RR, .75; 95% CI, .48 to 1.18; P = .22). PET status conferred no influence on graft-versus-host disease. A positive PET scan before HCT is associated with increased relapse risk but should not be interpreted as a barrier to a successful allograft. PET status does not appear to predict survival after allogeneic HCT for NHL. PMID:25983043

    We analyzed the outcomes of 248 (61% male) adult recipients of HLA-matched unrelated and HLA-mismatched related donor hematopoietic cell transplantation (HCT) for non-Hodgkin lymphoma (NHL) after reduced or lower intensity conditioning (RIC), reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) from 1997 to 2004. Median age was 52 (range, 18–72 yrs); 31% had a Karnofsky performance score <90. Follicular NHL (43%) was the major histology. Incidence of grades II–IV acute graft-versus-host disease (GVHD) was 43% at 100 days; and chronic GVHD was 44% at three years. Treatment-related mortality (TRM) at 100 days was 24%. Three-year overall survival (OS) and progression-free survival (PFS) were 41% and 32%, respectively. In multivariate analysis, use of anti-thymocyte globulin (ATG) and HLA mismatch were associated with increased TRM. High-grade histology, ATG use and chemotherapy resistance were associated with lower progression-free survival (PFS). Older age, shorter interval from diagnosis to HCT, non-TBI conditioning regimens, ex vivo T-cell depletion and HLA-mismatched unrelated donors were associated with mortality. GVHD did not influence relapse or PFS. Older age, aggressive histology and chemotherapy resistance correlated with poorer survival. For selected patients with NHL, lack of an available sibling donor should not be a barrier to allogeneic HCT. PMID:22155506

    Although the application of Hematopoietic Cell Transplantation-specific Comorbidity Index (HCT-CI) has enabled better prediction of transplant-related mortality (TRM) in allogeneic hematopoietic stem cell transplants (AHSCT), data from developing countries are scarce. This study prospectively evaluated the HCT-CI and the Adult Comorbidity Evaluation (ACE-27), in its original and in a modified version, as predictors of post-transplant complications in adults undergoing a first related or unrelated AHSCT in Brazil. Both bone marrow (BM) and peripheral blood stem cells (PBSC) as graft sources were included. We analyzed the cumulative incidence of granulocyte and platelet recovery, sinusoidal obstructive syndrome, acute and chronic graft-versus-host disease, relapse and transplant-related mortality, and rates of event-free survival and overall survival. Ninety-nine patients were assessed. Median age was 38 years (18–65 years); HCT-CI ≥ 3 accounted for only 8% of cases; hematologic malignancies comprised 75.8% of the indications for AHSCT. There was no association between the HCT-CI or the original or modified ACE-27 with TRM or any other studied outcomes after AHSCT. These results show that, in the population studied, none of the comorbidity indexes seem to be associated with AHSCT outcomes. A significantly low frequency of high-risk (HCT-CI ≥ 3) in this Brazilian population might justify these results. PMID:26394228

    Because the outcome of allogeneic hematopoietic cell transplantation (HCT) is predominantly influenced by disease type and status, it is essential to be able to stratify patients undergoing HCT by disease risk. The Disease Risk Index (DRI) was developed for this purpose. In this study, we analyzed 13,131 patients reported to the Center for International Blood and Marrow Transplant Research who underwent HCT between 2008 and 2010. The DRI stratified patients into 4 groups with 2-year overall survival (OS) ranging from 64% to 24% and was the strongest prognostic factor, regardless of age, conditioning intensity, graft source, or donor type. A randomly selected training subgroup of 9849 patients was used to refine the DRI, using a multivariable regression model for OS. This refined DRI had improved prediction ability for the remaining 3282 patients compared with the original DRI or other existing schemes. This validated and refined DRI can be used as a 4- or 3-group index, depending on the size of the cohort under study, for prognostication; to facilitate the interpretation of single-center, multicenter, or registry studies; to adjust center outcome data; and to stratify patients entering clinical trials that enroll patients across disease categories.

    Disease relapse is the most common cause of treatment failure after allogeneic stem cell transplantation for acute myeloid leukemia and myelodysplastic syndromes, yet treatment options for such patients remain extremely limited. Azacitidine is an important new therapy in high-risk myelodysplastic syndromes and acute myeloid leukemia but its role in patients who relapse post allograft has not been defined. We studied the tolerability and activity of azacitidine in 181 patients who relapsed after an allograft for acute myeloid leukemia (n=116) or myelodysplastic syndromes (n=65). Sixty-nine patients received additional donor lymphocyte infusions. Forty-six of 157 (25%) assessable patients responded to azacitidine therapy: 24 (15%) achieved a complete remission and 22 a partial remission. Response rates were higher in patients transplanted in complete remission (P=0.04) and those transplanted for myelodysplastic syndromes (P=0.023). In patients who achieved a complete remission, the 2-year overall survival was 48% versus 12% for the whole population. Overall survival was determined by time to relapse post transplant more than six months (P=0.001) and percentage of blasts in the bone marrow at time of relapse (P=0.01). The concurrent administration of donor lymphocyte infusion did not improve either response rates or overall survival in patients treated with azacitidine. An azacitidine relapse prognostic score was developed which predicted 2-year overall survival ranging from 3%–37% (P=0.00001). We conclude that azacitidine represents an important new therapy in selected patients with acute myeloid leukemia/myelodysplastic syndromes who relapse after allogeneic stem cell transplantation. Prospective studies to confirm optimal treatment options in this challenging patient population are required. PMID:27081178

    Background. The purpose of this study was to investigate the prognostic importance of functional capacity in patients undergoing allogeneic hematopoietic cell transplantation (HCT) for hematological malignancies. Patients and Methods. Using a retrospective design, 407 patients completed a 6-minute walk distance (6MWD) test to assess functional capacity before HCT; 193 (47%) completed a 6MWD test after hospital discharge. Cox proportional hazards regression was used to estimate the risk of nonrelapse mortality (NRM) and overall survival (OS) according to the 6MWD category (<400 m vs. ≥400 m) and the change in 6MWD (before HCT to discharge) with or without adjustment for Karnofsky performance status (KPS), age, and other prognostic markers. Results. Compared with <400 m, the unadjusted hazard ratio for NRM was 0.65 (95% confidence interval, 0.44–0.96) for a 6MWD ≥400 m. A 6MWD of ≥400 m provided incremental information on the prediction of NRM with adjustment for age (p = .032) but not KPS alone (p = .062) or adjustment for other prognostic markers (p = .099). A significant association was found between the 6MWD and OS (p = .027). A 6MWD of ≥400 m provided incremental information on the prediction of OS with adjustment for age (p = .032) but not for other prognostic markers (p > .05 for all). Patients presenting with a pre-HCT 6MWD of <400 m and experiencing a decline in 6MWD had the highest risk of NRM. Conclusion. The 6MWD is a significant univariate predictor of clinical outcomes but did not provide prognostic information beyond that of traditional prognostic markers in HCT. Implications for Practice: The pretransplant 6-minute walk test is a significant univariate predictor of clinical outcomes in hematological patients beyond age but not beyond that of performance status. On this basis, 6-minute walk distance testing should not be considered part of the standard battery of assessments for risk stratification before hematopoietic cell transplantation

    Aim To investigate the association of adiponectin and resistin levels in patients undergoing hematopoietic stem cell transplantation (HSCT) with the clinical outcome, including the occurrence of acute and chronic graft-vs-host disease (GVHD), non-relapse mortality, and overall survival. Methods We prospectively collected serum samples from 40 patients undergoing either autologous (n = 12; 10 male) or allogeneic (n = 28; 11 male) HSCT for up to 12 months post HSCT and determined adiponectin and resistin serum concentrations using enzyme-linked immunosorbent assay. Results There were no significant differences in adiponectin levels (18.5 vs 9.3 µg/mL, P = 0.071) and adiponectin/BMI ratio (0.82 vs 0.39, P = 0.068) between patients with acute GVHD grades 2-4 and autologous controls. However, resistin values were significantly lower in patients with acute GVHD grades 2-4 than in autologous controls (4.6 vs 7.3 ng/mL, P = 0.030). Adiponectin levels were higher in patients with chronic GVHD (n = 17) than in autologous controls (13.5 vs 7.6 µg/mL, P = 0.051), but the difference was not significant. Adiponectin/BMI ratio was significantly higher in patients with chronic GVHD than in autologous controls (0.59 vs 0.25, P = 0.006). Patients dying from relapse also had significantly lower adiponectin levels (8.2 µg/mL) and adiponectin/BMI ratio (0.3) on admission than surviving allogeneic (15.8 µg/mL, P = 0.030 and 0.7, P = 0.004) and surviving autologous patients (19.2 µg/mL, P = 0.031 and 0.7, P = 0.021). Conclusion Adiponectin and resistin levels were altered in patients with acute and chronic GVHD compared to autologous controls and were associated with overall survival and relapse mortality in patients undergoing allogeneic HSCT.

    We evaluated 26 901 patients who underwent allogeneic hematopoietic cell transplantation (HCT) at 271 centers worldwide to define patterns of posttransplantation lymphoproliferative disorders (PTLDs). PTLDs developed in 127 recipients, with 105 (83%) cases occurring within 1 year after transplantation. In multivariate analyses, we confirmed that PTLD risks were strongly associated (P < .001) with T-cell depletion of the donor marrow, antithymocyte globulin (ATG) use, and unrelated or HLA-mismatched grafts (URD/HLA mismatch). Significant associations were also confirmed for acute and chronic graft-versus-host disease. The increased risk associated with URD/HLA-mismatched donors (RR = 3.8) was limited to patients with T-cell depletion or ATG use (P = .004). New findings were elevated risks for age 50 years or older at transplantation (RR = 5.1; P < .001) and second transplantation (RR = 3.5; P < .001). Lower risks were found for T-cell depletion methods that remove both T and B cells (alemtuzumab and elutriation, RR = 3.1; P = .025) compared with other methods (RR = 9.4; P = .005 for difference). The cumulative incidence of PTLDs was low (0.2%) among 21 686 patients with no major risk factors, but increased to 1.1%, 3.6%, and 8.1% with 1, 2, and more than 3 major risk factors, respectively. Our findings identify subgroups of patients who underwent allogeneic HCT at elevated risk of PTLDs for whom prospective monitoring of Epstein-Barr virus activation and early treatment intervention may be particularly beneficial.

    An elevated ferritin before allogeneic hematopoietic cell transplantation (HCT) is an adverse prognostic factor for overall survival (OS) and non-relapse mortality (NRM). Because ferritin is an imperfect surrogate of iron stores, the prognostic role of iron overload remains unclear. We conducted a patient-level meta-analysis of 4 studies that used magnetic resonance imaging to estimate pre-HCT liver iron content (LIC). An elevated LIC was not associated with a significant increase in mortality: the hazard ratio (HR) for mortality associated with LIC>7 mg/gdw (primary endpoint) was 1.4 (p=0.18). In contrast, ferritin >1000 ng/ml was a significant prognostic factor (HR for mortality 1.7, p=0.036). There was, however, no significant association between ferritin>2500 and mortality. This meta-analysis suggests that iron overload, as assessed by LIC, is not a strong prognostic factor for OS in a general adult HCT population. Our data also suggest that ferritin is an inadequate surrogate for iron overload in HCT. PMID:24769316

    We report cases of three patients of refractory ascites without other fluid retention that occurred around five months after allogeneic hematopoietic stem cell transplantation (allo-HSCT). All three patients expired and postmortem examinations revealed unexpected liver fibrosis lacking histological evidences of graft-versus-host-disease (GVHD). The three patients showed normal hepatic function and size before transplantation. During their clinical courses, serum biochemistry test showed no elevation of hepatic enzymes and bilirubin; however, imaging studies demonstrated hepatic atrophy at the onset of ascites. One of the liver specimens showed bile obstruction, which could be seen in hepatic damage by GVHD. Although ascites resulting from venoocclusive disease in early phase allo-HSCT is well documented, ascites associated with hepatic fibrosis in late phase allo-HCST has not been reported. Further clinico-pathological studies on similar patients should be required to ascertain refractory ascites associated with liver fibrosis after allo-HSCT. PMID:27499838

    Allogeneic hematopoietic stem cell transplantation (SCT) can cure a proportion of patients with myelodysplastic syndromes (MDS). However, treatment related toxicities, graft versus host disease, infectious complications and relapse remain major problems post transplant. Further, recent new developments with innovative drugs including hypomethylating agents (HMA) have extended the therapeutic alternatives for our patients. Nevertheless, with the introduction of reduced-intensity conditioning and thereby reducing early mortality, transplant numbers in MDS patients have significantly increased recently. In the absence of prospective randomized trials emphasis should be put on patient selection and optimization of the pre- and post-transplant treatment in order to achieve long-term disease control and at the same time maintain an adequate quality of life. With better understanding of disease biology and prognosis and with different types of conditioning regimens as well as different graft sources, a transplant strategy should be tailored to the individual host to maximize the benefits of this procedure.

    Patients with classic Hodgkin lymphoma (cHL) that has relapsed after autologous or allogeneic transplant have limited treatment options and a poor prognosis. Immunotherapy with agents that target the PROGRAMMED DEATH 1 (PD-1) receptor have demonstrated clinical activity with durable responses in early-phase clinical trials in this patient population; however, patients with a history of allogeneic stem cell transplantation (SCT) were intentionally excluded from participation in those studies due to concerns for reactivation of graft-versus-host disease (GVHD). We describe the clinical course of two patients with advanced cHL and prior treatment with allogeneic stem cell transplantation (SCT) that were treated with the PD-1 inhibitor pembrolizumab. Both patients had no active graft-versus-host disease (GVHD) at the time initiation of therapy and were maintained on low-dose prednisone. Treatment with pembrolizumab was well tolerated and not associated with reactivation of GVHD. Both patients responded (1 partial, 1 complete) and remain on therapy as of November 30, 2015. This report indicates that immunotherapy targeting the PD-1 pathway can be safely administered to patients with cHL and a history of allogeneic SCT and produce tumor responses. Further studies in this patient population are needed. PMID:26848626

    A 19-year-old woman complaining of fever and a sore throat was diagnosed with very severe aplastic anemia (AA) by bone marrow examination at a local hospital. Despite administration of antibiotics and granulocyte-colony stimulating factor to treat the soft tissue infection in her neck, her neutrophil count showed no increase. Because emergent allogeneic stem cell transplantation (SCT) was necessary, she was referred to our hospital. On admission, computed tomography revealed right-sided severe pharyngitis and lymphadenitis causing tracheal stenosis, and emergent intubation was required the next day. Granulocyte transfusion therapy (GTX) from related donors coupled with broad-spectrum antibiotic administration controlled the otherwise overwhelming infection. The patient received allogeneic peripheral blood SCT using a reduced-intensity conditioning regimen. After allogeneic SCT, successful engraftment was obtained. She was discharged from the hospital 59 days after allogeneic SCT. She remains alive and well, as of the latest follow up. This case clearly demonstrates that GTX is useful for controlling severe infection and enables patients with severe AA to receive allogeneic SCT safely. PMID:27169447

    Prior studies of allogeneic hematopoietic cell transplantation (HCT) therapy for the treatment of malignant or nonmalignant blood disorders assume a 30% likelihood that a patient will find a match among siblings and, therefore, a 70% likelihood of needing an unrelated donor source. This study utilizes birth data and statistical modeling to assess the adequacy of these estimates to describe the probability among US population cohorts segmented by race/ethnicity and age, including ages of greatest HCT utilization. Considerable variation in the likelihood of an HLA-identical sibling was found, ranging from 13% to 51%, depending upon patient age and race/ethnicity. Low sibling match probability, compounded with increased genetic diversity and lower availability among unrelated donors, put the youngest minority patients at the greatest risk for not finding a suitable related or unrelated HCT donor. Furthermore, the present 40-year decline in birth rates is expected to lead to 1.5-fold decrease in access to a matched sibling for today's young adults (18 to 44 years of age) when they reach peak HCT utilization years (near age 61 years) versus their contemporary adult counterparts (44 to 64 years). Understanding the sibling match probability by race/ethnicity and age cohort leads to forecasting the demand for unrelated HCT sources. PMID:26403513

    Allogeneic peripheral blood stem cells transplantation (allo-PBSCT) or allogeneic bone marrow transplantation (allo-BMT) have been widely used to treat patients exhibiting certain severe illnesses. However, previous studies have shown that the biological materials of allo-PBSCT or allo-BMT recipients may not constitute credible materials for personal identification. In the present study, four types of commonly used samples were collected from a male individual following gender-matched allo-BMT. Autosomal short tandem repeat (STR) and Y-STR markers analysis, based on polymerase chain reaction, were used to evaluate the chimerism status. The results showed that the blood sample were all donor type, the buccal swab sample were mixed chimerism, and the sperm and hair follicle samples maintained a recipient origin of 100%. In conclusion, identical results were obtained by the two methods and it was confirmed that DNA extracted from hair follicles and sperm can be used as a reference for the pre-transplant genotype DNA profile of the recipient in the gender-match allo-BMT or -PBSCT.

    The utility of routine chimerism analysis as a prognostic indicator of subsequent outcomes after allogeneic hematopoietic cell transplantation (HCT) with myeloablative conditioning regimens remains controversial. To address this controversy, routine chimerism test results at 2 – 6 months after HCT with myeloablative conditioning regimens were evaluated for association with subsequent risks of chronic graft versus host disease (GVHD), non-relapse mortality (NRM), relapse and overall mortality. Only 70 (5%) of 1304 patients had <95% donor-derived cells in the marrow. Low donor chimerism in the marrow occurred predominantly among patients with low risk disease as compared to higher risk diseases and was significantly associated with a reduced risk of chronic GVHD. Among 673 patients tested, 164 (24%) had <85% donor-derived T cells in the blood. Low donor T cell chimerism occurred predominantly among patients with low risk disease as compared to higher risk diseases, among those who had conditioning with busulfan as compared to TBI, and among those with lower grades of acute GVHD. Low donor T cell chimerism in the blood was significantly associated with a reduced risk of chronic GVHD, but not with the risks of relapse, NRM or overall mortality. Routine testing of chimerism in the marrow and blood at 2 – 6 months after HCT with myeloablative conditioning regimens may be helpful in documenting engraftment in clinical trials but provides only limited prognostic information in clinical practice.

    Allogeneic hematopoietic cell transplantation (alloHCT) may be the only curative option for some older adults with hematologic malignancies, and its associated risks of significant morbidity and mortality warrant a clear, informed decision-making process. As older adults have not been transplanted routinely until recent years, younger people have been the prototypical group around whom the current process has developed. Yet, this process is applied to older adults who have different considerations than younger patients when making their transplant decision. Older adults do not have the open-ended lives of younger patients and are entitled to consider how to spend their remaining time. They also possess maturity and experience, and with proper knowledge, they can make informed choices rather than moving forward in the transplant process unaware. Notably, older patients face similar problems with the informed decision-making process in nephrology. Strategies such as providing education about alloHCT gradually and repeatedly during induction, presenting recent knowledge from the literature in plain language, and utilizing a team approach to patient education may help older adults make the best decision about transplant in light of their situation and values. Understanding when and how older adults decide on alloHCT is an important first step to further exploring this problem. PMID:26457910

    The impact of extramedullary disease (EMD) in AML on the outcomes of allogeneic hematopoietic cell transplantation (alloHCT) is unknown. Using data from the Center for International Blood and Marrow Transplant Research, we compared the outcomes of patients who had EMD of AML at any time before transplant, with a cohort of AML patients without EMD. We reviewed data from 9797 AML patients including 814 with EMD from 310 reporting centers and 44 different countries, who underwent alloHCT between and 1995 and 2010. The primary outcome was overall survival (OS) after alloHCT. Secondary outcomes included leukemia-free survival (LFS), relapse rate and treatment-related mortality (TRM). In a multivariate analysis, the presence of EMD did not affect either OS (hazard ratio 1.00, 95% confidence interval (CI) 0.91-1.09), LFS (0.98, 0.89-1.09), TRM (relative risk 0.92, 95% CI 0.80-1.16, P=0.23) or relapse (relative risk=1.03, 95% CI, 0.92-1.16; P=0.62). Furthermore, the outcome of patients with EMD was not influenced by the location, timing of EMD, or intensity of conditioning regimen. The presence of EMD in AML does not affect transplant outcomes and should not be viewed as an independent adverse prognostic feature. PMID:25915806

    Purpose: We have demonstrated that toxicities are acceptable with total marrow irradiation (TMI) at 16 Gy without chemotherapy or TMI at 12 Gy and the reduced intensity regimen of fludarabine/melphalan in patients undergoing hematopoietic cell transplantation (HCT). This article reports results of a study of TMI combined with higher intensity chemotherapy regimens in 2 phase I trials in patients with advanced acute myelogenous leukemia or acute lymphoblastic leukemia (AML/ALL) who would do poorly on standard intent-to-cure HCT regimens. Methods and Materials: Trial 1 consisted of TMI on Days -10 to -6, etoposide (VP16) on Day -5 (60 mg/kg), and cyclophosphamide (CY) on Day -3 (100 mg/kg). TMI dose was 12 (n=3 patients), 13.5 (n=3 patients), and 15 (n=6 patients) Gy at 1.5 Gy twice daily. Trial 2 consisted of busulfan (BU) on Days -12 to -8 (800 {mu}M min), TMI on Days -8 to -4, and VP16 on Day -3 (30 mg/kg). TMI dose was 12 (n=18) and 13.5 (n=2) Gy at 1.5 Gy twice daily. Results: Trial 1 had 12 patients with a median age of 33 years. Six patients had induction failures (IF), and 6 had first relapses (1RL), 9 with leukemia blast involvement of bone marrow ranging from 10%-98%, 5 with circulating blasts (24%-85%), and 2 with chloromas. No dose-limiting toxicities were observed. Eleven patients achieved complete remission at Day 30. With a median follow-up of 14.75 months, 5 patients remained in complete remission from 13.5-37.7 months. Trial 2 had 20 patients with a median age of 41 years. Thirteen patients had IF, and 5 had 1RL, 2 in second relapse, 19 with marrow blasts (3%-100%) and 13 with peripheral blasts (6%-63%). Grade 4 dose-limiting toxicities were seen at 13.5 Gy (stomatitis and hepatotoxicity). Stomatitis was the most frequent toxicity in both trials. Conclusions: TMI dose escalation to 15 Gy is possible when combined with CY/VP16 and is associated with acceptable toxicities and encouraging outcomes. TMI dose escalation is not possible with BU/VP16 due to

    In patients with relapsed ALL, minimal residual disease (MRD) identified prior to allogeneic hematopoietic cell transplantation (HCT) is a strong predictor of relapse. We report our experience using a combination of reduced-dosing clofarabine, CY and etoposide as a 'bridge' to HCT in eight patients with high risk or relapsed ALL and pre-HCT MRD. All patients had detectable MRD (>0.01%, flow cytometry) at the start of therapy with all eight achieving MRD reduction following one cycle. The regimen was well tolerated with seven grade 3/4 toxicities occurring among four of the eight patients. Five patients (62.5%) are alive, one died from relapse (12.5%) and two from transplant-related mortality (25%). The combination of reduced-dose clofarabine, CY and etoposide as bridging therapy appears to be well tolerated in patients with relapsed ALL and is effective in reducing pre-HCT MRD. PMID:24317126

    Vancomycin-resistant enterococcus (VRE) is a well-known infectious complication among immunocompromised patients. We performed a retrospective analysis to identify risk factors for the development of VRE bacteremia (VRE-B) within 15 months after allogeneic hematopoietic cell transplantation (alloHCT) and to determine its prognostic importance for other post-transplant outcomes. Eight hundred consecutive adult patients who underwent alloHCT for hematologic diseases from 1997 to 2011 were included. Seventy-six (10%) developed VRE-B at a median of 46 days post transplant. Year of transplant, higher HCT comorbidity score, a diagnosis of ALL, unrelated donor and umbilical cord blood donor were all significant risk factors on multivariable analysis for the development of VRE-B. Sixty-seven (88%) died within a median of 1.1 months after VRE-B, but only four (6%) of these deaths were attributable to VRE. VRE-B was significantly associated with worse OS (hazard ratio 4.28, 95% confidence interval 3.23-5.66, P<0.001) in multivariable analysis. We conclude that the incidence of VRE-B after alloHCT has increased over time and is highly associated with mortality, although not usually attributable to VRE infection. Rather than being the cause, this may be a marker for a complicated post-transplant course. Strategies to further enhance immune reconstitution post transplant and strict adherence to infection prevention measures are warranted. PMID:25111516

    To assess the impact of the genetic variation in toll-like receptors (TLR) on outcome after allogeneic myeloablative conditioning hematopoietic cell transplantation (HCT) we have investigated 29 single nucleotide polymorphisms (SNP) across 10 TLRs in 816 patients and donors. Only donor genotype of TLR8 rs3764879, which is located on the X chromosome, was significantly associated with outcome at the Bonferroni corrected level P≤0.001. Male hemizygosity and female homozygosity for the minor allele were significantly associated with disease free survival (DFS) (hazard ratio (HR) 1.47 (95% confidence interval (CI) 1.16–1.85); P=0.001). Further analysis stratified by donor sex due to confounding by sex, was suggestive for associations with overall survival (male donor: HR 1.41 (95% CI 1.09–1.83), P=0.010); female donor: (HR 2.78 (95% CI 1.43–5.41), P=0.003), DFS (male donor: HR 1.45 (95% CI 1.12–1.87), P=0.005; female donor: HR 2.34 (95% CI 1.18–4.65), P=0.015) and treatment related mortality (male donor: HR 1.49 (95% CI 1.09–2.04), P=0.012; female donor: HR 3.12 (95% CI 1.44–6.74), P=0.004). In conclusion our findings suggest that the minor allele of TLR8 rs3764879 of the donor is associated with outcome after myeloablative conditioned allogeneic HCT. PMID:25464115

    Early palliative care (EPC) for patients with metastatic solid tumors is now standard of care, but the effect of EPC in hematopoietic cell transplantation (HCT) is less well understood. We studied the acceptability of pre-HCT EPC as measured by trial participation, changes in patient-reported outcomes, and follow-up with palliative care providers. English-speaking adults (age >17 years) with an HCT comorbidity index of ≥ 3, relapse risk > 25%, or planned HLA-mismatched allogeneic or myeloablative HCT received EPC before HCT admission with monthly or more frequent visits. Twenty-two (69%) of 32 subjects provided consent; 2 were later excluded (HCT cancelled, consent retracted) for a 63% participation rate. Comfort with EPC was high (82% very comfortable). Subjects reported stable or improved mood and sense of hope, without apparent negative effects with a median of 3 visits. Follow-up surveys were returned by 75% of participants at 60 days and by 65% at 90 days. Four (20%) were admitted to the intensive care unit before day 100 and 3 (15%) received life-support measures. Five (25%) died with median follow-up of 14 months. EPC is feasible, acceptable, and has the potential to improve the HCT experience, whether or not the patient survives. EPC for HCT patients should be tested in a randomized trial. PMID:26976242

    Allogeneic stem cell transplantation (alloSCT) represents a curative therapeutic option for patients with myelodysplastic syndrome (MDS), but relapse and non-relapse mortality (NRM) limit treatment efficacy. Based on our previous observation in acute myeloid leukemia we investigated the impact of pre-transplant weight loss on post-transplant outcome in MDS patients. A total of 111 patients diagnosed with MDS according to WHO criteria transplanted between 2000 and 2012 in three different transplant centers were included into the analysis. Data on weight loss were collected from medical records prior to conditioning therapy and 3–6 months earlier. Patient, disease and transplant characteristics did not differ between patients with weight loss (2–5%, n = 17; > 5%, n = 17) and those without (n = 77). In a mixed effect model, weight loss was associated with higher risk MDS (p = 0.046). In multivariable analyses, pre-transplant weight loss exceeding 5% was associated with a higher incidence of relapse (p < 0.001) and NRM (p = 0.007). Pre-transplant weight loss of 2–5% and > 5% were independent predictors of worse disease-free (p = 0.023 and p < 0.001, respectively) and overall survival (p = 0.043 and p < 0.001, respectively). Our retrospective study suggests that MDS patients losing weight prior to alloSCT have an inferior outcome after transplantation. Prospective studies addressing pre-transplant nutritional interventions are highly warranted. PMID:26360778

    Wilms' tumor gene 1 (WT1) is overexpressed in leukemia and WT1-derived CD8(+) T-cell epitopes for immunotherapies targeting WT1 have been defined. Here, we analyzed expression of WT1 in 226 peripheral blood and bone marrow samples from patients with acute myeloid leukemia or myelodysplastic syndrome (AML/MDS) before and after allogeneic stem cell transplantation (SCT). Transcripts were assessed by quantitative polymerase chain reaction, and WT1-specific CD8+ cytotoxic T cells (CTL) were monitored by tetramer staining and enzyme-linked immunospot (ELISPOT) assays. Reduction of WT1 levels correlated with a longer survival (p < 0.01). Increment of WT1 transcripts eventually resulted in relapse and subsequent death of the patients. In patients with longer survival and continuous complete remission (cCR) after SCT, higher and enduring frequencies of WT1-specific CTL than in patients developing a relapse were detected. These cells were effector T cells secreting interferon gamma and granzyme B. In summary, WT1 is a suitable marker for the detection of minimal residual disease after SCT or chemotherapy. A rising WT1 signal correlated with a dismal prognosis of the patients. WT1-specific CD8(+) T cells might contribute to the maintenance of a cCR. Targeting WT-1 by peptide/protein vaccination as well as adoptive transfer of genetically modified T cells are future options in the individualized therapy for AML/MDS patients. PMID:26519872

    The study analyzed outcomes of a consecutive case series of 37 patients with peripheral T-cell non-Hodgkin lymphoma, from related and unrelated donors, using allogeneic hematopoietic cell transplantation (allo-HCT), between the years 2000 and 2007. All patients were pretreated; the majority had either relapsed or progressive disease (n=25, 68%), 13 had cutaneous histologies (CTCL), and all were ineligible for autologous transplant. Fully ablative conditioning regimens were used in 13 patients while 24 patients underwent reduced intensity conditioning (RIC). At five years the overall survival (OS) and progression-free survival (PFS) probabilities were 52.2% and 46.5%, respectively. At the time of analysis, 9 (24.3%) patients had either relapsed (n=6) or progressed (n=3) post allo-HCT. The cumulative incidences of relapse/progression and non-relapse mortality at 5 years were 24.3% and 28.9%. No statistically significant variables for survival or relapse were discovered by univariate Cox-regression analysis of disease and patient characteristics; differences between CTCL and other histologies were not significant. The median follow-up of 64.0 months (range: 16.4–100.4) indicates a mature data-set with probable cure in the survivors. The relapse/progression curves reached and maintained plateaus after 1 year post-transplant, demonstrating that long-term disease control is possible after allo-HCT in PTCL patients with advanced disease.

    Invasive fungal infections are an important cause of morbidity and mortality after allogeneic haematopoietic stem cell transplantation. We evaluated, in our allogeneic stem cell transplant patients, the effect on the incidence of invasive fungal infection during neutropenia of a strategy combining a diagnostic-driven approach with chemoprophylaxis during higher risk periods of graft vs. host disease and prolonged neutropenia, using itraconazole oral solution with parenteral voriconazole bridging. One hundred and thirty patients admitted for allogeneic stem cell transplantation within two predefined 20 month periods were included in the study. Data for all patients were collected prospectively. Implementation of the protocol resulted in the administration of more prophylactic antifungals to more patients. Following implementation, there was a non-significant decrease in the overall number of invasive fungal infections (IFI) [11 of 65 patients (17.2%) vs. 4 of 65 patients (6.2%, P = 0.051)], as well as in the occurrence of invasive mould infections [8 of 65 patients (12.5%) vs. 2 of 65 patients (3.1%, P = 0.054)]. Survival rates at three and 6 months were not significantly affected. A combined diagnostic-driven approach and antifungal prophylaxis with oral itraconazole and an intravenous voriconazole bridging protocol, was associated with a reduced, albeit non-statistically significant, number of IFI in our medical centre.

    Improved diagnostic methods are needed for bronchiolitis obliterans syndrome (BOS), a serious complication after allogeneic hematopoietic cell transplantation (HCT) and lung transplantation. For protein candidate discovery, we compared plasma pools from HCT transplantation recipients with BOS at onset (n = 12), pulmonary infection (n = 16), chronic graft-versus-host disease without pulmonary involvement (n = 15) and no chronic complications after HCT (n = 15). Pools were labeled with different tags (isobaric tags for relative and absolute quantification), and two software tools identified differentially expressed proteins (≥1.5-fold change). Candidate proteins were further selected using a six-step computational biology approach. The diagnostic value of the lead candidate, matrix metalloproteinase 3 (MMP3), was evaluated by enzyme-linked immunosorbent assay in plasma of a verification cohort (n = 112) with and without BOS following HCT (n = 76) or lung transplantation (n = 36). MMP3 plasma concentrations differed significantly between patients with and without BOS (area under the receiver operating characteristic curve 0.77). Consequently, MMP3 represents a potential noninvasive blood test for diagnosis of BOS. PMID:26887344

    Background Most hypomethylating agent (HMA) responders with myelodysplastic syndrome (MDS) eventually need allogeneic stem cell transplantation (SCT) because they often acquire resistance to HMAs within two years of treatment. Considering the nature of MDS and the poor outcomes of SCT when performed after confirming the progression of MDS to acute myeloid leukemia (AML), allogeneic SCT should be performed with caution in patients with low-risk MDS. Methods To address low-risk MDS, the Korean AML/MDS working party group designed a survey for 34 MDS experts in Korea on therapeutic HMA and allogeneic SCT policies for low-risk MDS. The level of consensus was defined as the percentage of agreement among the experts. Results With regard to the optimal time for allogeneic SCT for HMA responders with MDS-RA, 76% experts agreed that allogeneic SCT should be performed when a patient has a low platelet count. With regard to the relapse pattern that was most commonly found during HMA treatment in responding patients with MDS-RA, 54% experts agreed that the most common pattern that indicated HMA failure was the gradual worsening of cytopenia. Conclusion The optimal time to perform allogeneic SCT in RA patients who achieved hematologic complete remission during HMA treatment is when the platelet count decreases. However, these suggestions need to be evaluated in larger future studies. Therefore, careful decisions should be taken at each step of allogeneic SCT to maximize the outcomes for patients with MDS-RA and iron overload. PMID:27104191

    Long-term survival after allogeneic hematopoietic stem cell transplantation requires intact immunosurveillance, which is hampered by lymphoid organ damage associated with conditioning therapy, graft-versus-host disease, and immunosuppression. Our study aimed to identify the mechanisms contributing to sustained low memory B cell numbers after transplantation. Peripheral B and T cell subset recovery and functional marker expression were investigated in 35 acute leukemic patients up to 1 year after transplantation. Apoptosis of B cells after CD40/TLR-9, CD40/BCR, and CD40/BCR/TLR-9-dependent stimulation and drug efflux capacity were analyzed. One half of the patients suffered from infections after day 180. All patients had strongly diminished CD27(+) memory B cells despite already normalized total B cell numbers and fully recovered CD27(-)IgD(-) memory B cells, putatively of extra-follicular origin. Circulating memory follicular helper T cells were reduced in the majority of patients as well. Naïve B cells exhibited a decreased expression of CXCR5, which mediates follicular B cell entry. Additionally, a lower HLA-DR expression was found on naïve B cells, impairing antigen presentation. Upon CD40/TLR-9-dependent activation, B cells underwent significantly increased apoptosis paralleled by an aberrant up-regulation of Fas-L on activated T cells and Fas on resting B cells. Significantly increased B cell apoptosis was also observed after CD40/BCR and CD40/BCR/TLR-9-dependent activation. Drug efflux capacity of naïve B cells was diminished in cyclosporin A-treated patients, additionally contributing to an apoptosis-prone phenotype. We conclude that B cell survival and migration and T cell communication defects are contributing candidates for an impaired germinal center formation of memory B cells after allogeneic hematopoietic stem cell transplantation. Follow-up studies should evaluate effectiveness of revaccinations on the cellular level and should

    Allogeneic stem cell transplantation (SCT) is currently the only curative treatment option for chronic myeloid leukemia (CML) patients with BCR-ABL T315I mutations. We report the outcome of SCT in 22 patients with T315I(+) CML, most (n = 16) from haploidentical family donors (HID-SCT). At the time the mutation was detected, 8 patients were in the chronic phase (CP), 7 in the accelerated phase (AP), and 7 in the blast phase (BP). At the time of SCT 7 were in the CP, 8 in the AP or returning to the CP post-AP (AP/AP-CPn), and 7 in the BP or returning to CP post-BP (BP/BP-CPn). The cumulative incidence of grades III to IV acute graft-versus-host disease was 9.1%. Chronic graft-versus-host disease was observed in 60.0% of patients, including 25.0% who suffered from severe disease. Four patients died of transplant-related complications at a median interval from SCT of 16.3 months. The estimated 2-year leukemia-free survival rate was 80.0%, 72.9%, and 0% in CP, AP/AP-CPn and BP/BP-CPn groups at the time of SCT, respectively. After a median follow-up of 17.3 months from SCT, 14 patients are alive, including 13 in complete molecular response and 1 with an extramedullary relapse. In conclusion, HID-SCT is a potentially curative treatment for T315I + CML patients. For patients in CP/AP, immediate SCT might result in promising survival. The outcome of patients in BP with T315I(+) mutation remains very poor. PMID:26995693

    Although immunosuppressive treatments and target concentration intervention (TCI) have significantly contributed to the success of allogeneic haematopoietic cell transplantation (alloHCT), there is currently no consensus on the best immunosuppressive strategies. Compared with solid organ transplantation, alloHCT is unique because of the potential for bidirectional reactions (i.e. host-versus-graft and graft-versus-host). Postgraft immunosuppression typically includes a calcineurin inhibitor (cyclosporine or tacrolimus) and a short course of methotrexate after high-dose myeloablative conditioning, or a calcineurin inhibitor and mycophenolate mofetil after reduced-intensity conditioning. There are evolving roles for the antithymyocyte globulins (ATGs) and sirolimus as postgraft immunosuppression. A review of the pharmacokinetics and TCI of the main postgraft immunosuppressants is presented in this two-part review. All immunosuppressants are characterized by large intra- and interindividual pharmacokinetic variability and by narrow therapeutic indices. It is essential to understand immunosuppressants' pharmacokinetic properties and how to use them for individualized treatment incorporating TCI to improve outcomes. TCI, which is mandatory for the calcineurin inhibitors and sirolimus, has become an integral part of postgraft immunosuppression. TCI is usually based on trough concentration monitoring, but other approaches include measurement of the area under the concentration-time curve (AUC) over the dosing interval or limited sampling schedules with maximum a posteriori Bayesian personalization approaches. Interpretation of pharmacodynamic results is hindered by the prevalence of studies enrolling only a small number of patients, variability in the allogeneic graft source and variability in postgraft immunosuppression. Given the curative potential of alloHCT, the pharmacodynamics of these immunosuppressants deserves to be explored in depth. Development of

    In recent years, several safety alerts have questioned or restricted the use of some pharmacological alternatives to allogeneic blood transfusion in established indications. In contrast, there seems to be a promotion of other alternatives, based on blood products and/or antifibrinolytic drugs, which lack a solid scientific basis. The Multidisciplinary Autotransfusion Study Group and the Anemia Working Group España convened a multidisciplinary panel of 23 experts belonging to different healthcare areas in a forum for debate to: 1) analyze the different safety alerts referred to certain transfusion alternatives; 2) study the background leading to such alternatives, the evidence supporting them, and their consequences for everyday clinical practice, and 3) issue a weighted statement on the safety of each questioned transfusion alternative, according to its clinical use. The members of the forum maintained telematics contact for the exchange of information and the distribution of tasks, and a joint meeting was held where the conclusions on each of the items examined were presented and discussed. A first version of the document was drafted, and subjected to 4 rounds of review and updating until consensus was reached (unanimously in most cases). We present the final version of the document, approved by all panel members, and hope it will be useful for our colleagues. PMID:26183121

    To better understand the predictive factors and improve clinical outcome of allogeneic transplant for patients with myelodysplastic syndrome (MDS), we retrospectively analyzed the post-transplant outcome of 60 Southeast Asian patients with MDS. Multivariate analysis showed that WHO classification-based Prognostic Scoring System (WPSS) significantly affect overall survival (OS), progression-free survival (PFS), cumulative incidence of relapse (CIR), and cumulative incidence of non-relapse mortality (CINRM). Stratified by WPSS into very low/low, intermediate, high, and very high-risk categories, 3-year OS was 100, 61, 37, and 18% (p = 0.02); PFS was 100, 55, 32, and 18% (p = 0.014); CIR was 12, 24, 38, and 59% (p = 0.024); CINRM was 0, 6, 12, and 26% (p = 0.037), respectively. WHO classification, Revised International Prognostic Scoring System (IPSS-R), IPSS-R-defined cytogenetic risk groups, donor gender, and acute and chronic graft vs host disease (GVHD) also influenced different aspects of transplant outcome. We found that WPSS is a powerful predictor of post-transplant outcome. WPSS provides an important model not only for prognostication but also for exploration of further post-transplant measures such as immunological maneuvers or novel therapy to improve the poor outcome of high-risk patients.

    While allogeneic hematopoietic cell transplantation (HCT) may offer the best chance of cure for patients suffering from aggressive hematological malignancies such as acute myeloid leukemia, acute lymphoblastic leukemia, and myelodysplastic syndrome, successful outcomes for the subgroup of patients with high-risk disease remain disappointing and lag behind those of lower-risk patients. Because relatively high rates of relapse are an important contributor to these poor outcomes, efforts have explored approaches to increase the cytotoxic effects of treatment. Relapse rates have been shown to improve with the addition of increased doses of total body irradiation (TBI) and/or the introduction of additional chemotherapy to a HCT conditioning regimen. However, the increase in TBI dose and/or additional chemotherapy has also been associated with a significant increase in life-threatening toxicities, resulting in no change in overall survival. Radioimmunotherapy (RIT) has been employed as an adjunct to HCT where targeted delivery of radiation may allow for further escalation of therapy to reduce relapse with minimal toxicity. In this review we describe these efforts, including the benefits of escalating the dose of radiation to sites of hematologic disease prior to HCT, the various cellular targets for antibody-mediated delivery of radiation, as well as the rationale for incorporation of various radionuclides such as alpha emitters and beta emitters into the preparative regimen prior to HCT. Lastly, newer novel approaches such as pretargeted RIT (PRIT) are described as a method to further increase delivery of targeted radiation to hematological tissues while sparing noninvolved organs.

    Some studies on the predictive value of determining pulmonary function prior to allogeneic hematopoietic cell transplantation (allo-HCT) have shown a significant association between pulmonary function test (PFT) parameters and pulmonary complications, and mortality. However, the percentage of patients showing abnormalities in pretransplant PFT parameters is low. We comprehensively evaluated the effect of pretransplant PFT parameters, including a marker of small airway disease (ratio of the airflow rate of 50% vital capacity to the airflow rate of 25% vital capacity (V˙50/V˙25), on outcomes in 206 evaluable patients who underwent allo-HCT at our institute. Notable among the significant parameters in a univariable analysis, V˙50/V˙25 was the most powerful indicator of survival following allo-HCT (delta-Akaike information criterion [∆AIC] = 12.47, ∆χ(2)  = 14.47; P = 0.0001). Additionally, a pretransplant lung function score (pLFS) established by applying three parameters with superior predictive values including V˙50/V˙25 represented a better discriminating variable for the prediction of survival. Our data demonstrate that a pLFS incorporating a parameter of small airway disease, rather than the parameters of central airway obstruction, may be useful for predicting patient survival following allo-HCT.

    The impact of extramedullary disease (EMD) in AML on the outcomes of allogeneic hematopoietic cell transplantation (alloHCT) is unknown. Using data from the Center for International Blood and Marrow Transplant Research (CIBMTR) we compared the outcomes of patients who had EMD of AML at any time prior to transplant to a cohort of AML patients without EMD. We reviewed data AML from 9,797 patients including 814 with EMD from 310 reporting centers and 44 different countries who underwent alloHCT between and 1995–2010. The primary outcome was overall survival (OS) after alloHCT. Secondary outcomes included leukemia-free survival (LFS), relapse rate, and treatment-related mortality (TRM). In a multivariate analysis, the presence of EMD did not affect either OS (HR 1.00, 95% CI 0.91–1.09), LFS (0.98, 0.89–1.09), TRM (RR 0.92, 95% CI 0.80–1.16, p=0.23) or relapse (RR =1.03, 95% CI, 0.92–1.16; p=0.62). Furthermore, the outcome of patients with EMD was not influenced by the location, timing of EMD, or intensity of conditioning regimen. The presence of EMD in AML does not affect transplant outcomes and should not be viewed as an independent adverse prognostic feature. PMID:25915806

    Purpose Fludarabine monophosphate (fludarabine) is an integral component of many reduced-intensity conditioning regimens for hematopoietic cell transplantation (HCT). Fludarabine’s metabolite, 9-β-D-arabinofuranosyl-2-fluoroadenine (F-ara-A), undergoes cellular uptake and activation to form the active cytotoxic metabolite fludarabine triphosphate (F-ara-ATP), which inhibits cellular DNA synthesis in CD4+ and CD8+ cells. In this study, we evaluated whether fludarabine-based pharmacologic biomarkers were associated with clinical outcomes in HCT recipients. Methods Participants with hematologic diseases were conditioned with fludarabine and low-dose total body irradiation (TBI) followed by allogeneic HCT and post-grafting immunosuppression. After fludarabine administration, we evaluated pharmacological biomarkers for fludarabine – F-ara-A area under the curve (AUC) and the ratio of circulating CD4+ and CD8+ cells (CD4+/CD8+ ratio) after fludarabine administration – in 102 patients; F-ara-ATP accumulation rate in enriched CD4+ and CD8+ cells was evaluated in 34 and 36 patients, respectively. Results Interpatient variability in the pharmacological biomarkers was high, ranging from 3.7-fold (F-ara-A AUC) to 39-fold (F-ara-ATP in CD8+ cells). Circulating CD8+ cells were more sensitive to fludarabine administration. A population pharmacokinetic-based sampling schedule successfully allowed for estimation of F-ara-A AUC in this outpatient population. There was poor correlation between the F-ara-AUC and the F-ara-ATP accumulation rate in CD4+ (R2=0.01) and CD8+ cells (R2=0.00). No associations were seen between the four biomarkers and clinical outcomes (day +28 donor T-cell chimerism, acute graft-versus-host disease (GVHD), neutrophil nadirs, cytomegalovirus reactivation, chronic GVHD, relapse, non-relapse mortality, or overall mortality). Conclusions Considerable interpatient variability exists in pharmacokinetic and fludarabine-based biomarkers, but these biomarkers

    Diagnosis of adverse events following hematopoietic stem cell transplantation (HSCT) is mainly assigned to clinical symptoms or biopsies and thus rather unspecific and/or invasive. Studies indicate a distinct role of serum ferritin in HSCT and its correlation with adverse events such as graft-versus-host disease (GvHD), veno-occlusive disease (VOD), or infections. However, published data on the relevance of ferritin as a prognostic marker for post-transplant adverse events is rare, especially in pediatric patients. The present study analyzes ferritin plasma concentrations of 138 pediatric patients after HSCT between 2007 and 2010 including the control group (n = 21). Given the initial results regarding ferritin as a significant predictor for acute graft rejection after allogeneic HSCT in 9 of the 138 pediatric patients, serum ferritin of all pediatric patients (n = 27) who experienced graft rejection between 2007 and 2014 was analyzed. In addition, laboratory parameters including C-reactive protein (CRP), lactate dehydrogenase (LDH), fibrinogen, and D-dimer as possible differentiation markers for graft rejection were determined. In 24 (88.9 %) of the 27 pediatric patients with graft rejection, a significant increase of ferritin levels was observed 1 to 7 days prior to (P < 0.0001) and at the time of graft rejection (P < 0.0001). Moreover, there was an increase of D-dimer, CRP, LDH, and fibrinogen 1-7 days before graft rejection. Ferritin increased significantly at time of VOD (P = 0.0067), at time of intestinal (P < 0.0001) and skin GvHD (P < 0.0001), and at time of sepsis (P = 0.0005) and bacteremia (P = 0.0029). Ferritin might serve as a readily available identification marker for differentiation and identification of adverse events after HSCT in combination with other laboratory markers. PMID:26611853

    Most hematological malignancies occur in older patients. Until recently these patients and those with comorbidities were not candidates for treatment with allogeneic hematopoietic transplantation because they were unable to tolerate the heretofore used high-dose conditioning regimens. The finding that many of the cures achieved with allogeneic hematopoietic transplantation were due to graft-versus-tumor effects led to the development of less toxic and well-tolerated reduced intensity and nonmyeloablative regimens. These regimens enabled allogeneic engraftment, thereby setting the stage for graft-versus-tumor effects. This review summarizes the encouraging early results seen with the new regimens and discusses the two hurdles that need to be overcome for achieving even greater success, disease relapse and graft-versus-host disease.

    To reduce the risk of graft rejection after allogeneic hematopoietic cell transplantation (alloHCT) for patients with acquired severe aplastic anemia (SAA), we introduced an intensified preparative regimen consisting of treosulfan 10 g/m2/d on days -7, -6, cyclophosphamide 40 mg/kg/d on days -5, -4, -3, -2 and anti-thymocyte globulin 2 mg/kg/d on days -3, -2, -1. Six patients with the history of multiple transfusions were treated with alloHCT from either HLA-identical sibling (n=3) or an unrelated volunteer (n=3). Each, bone marrow and peripheral blood was used as a source of stem cells in three cases. All patients engrafted and achieved complete donor chimerism. None of the patients experienced severe organ toxicity. No severe acute graft-versus-host-disease (GVHD) was observed; two patients experienced extensive chronic GVHD. At the median follow-up of 14.5 (13-27) months all patients remained alive and disease-free. Our observation indicates that treosulfan + cyclophosphamide + antithymocyte globulin conditioning is well-tolerated and allows stable engraftment in acquired SAA. PMID:17494286

    BK virus (BKV) reactivation has been increasingly associated with the occurrence of late-onset hemorrhagic cystitis (HC) after allogeneic hematopoietic SCT (allo-HSCT) resulting in morbidity and sometimes mortality. We investigated the incidence, risk factors and outcome of BKV-HC in 323 consecutive adult patients undergoing allo-HSCT over a 5-year period. BK viremia values for HC staging were evaluated, as well as the medico-economic impact of the complication. Forty-three patients developed BKV-HC. In univariate analysis, young age (P=0.028), unrelated donor (P=0.0178), stem cell source (P=0.0001), HLA mismatching (P=0.0022) and BU in conditioning regimen (P=0.01) were associated with a higher risk of developing BKV-HC. In multivariate analysis, patients receiving cord blood units (CBUs) (P=0.0005) and peripheral blood stem cells (P=0.011) represented high-risk subgroups for developing BKV-HC. BK viremia was directly correlated to HC severity (P=0.011) with a 3 to 6-log peak being likely associated with grades 3 or 4 HC. No correlation was found between BKV-HC and acute graft versus host disease or mortality rate. Patients with BKV-HC required a significantly longer duration of hospitalization (P<0.0001), more RBC (P=0.0003) and platelet transfusions (P<0.0001). Over the 5-year study period, the financial cost of the complication was evaluated at \\[euro]2 376 076 ($3 088 899). Strategies to prevent the occurrence of late-onset BKV-HC after allo-HSCT are urgently needed, especially in CBU and peripheral blood stem cell recipients. BK viremia correlates with the severity of the disease. Prospective studies are required to test prophylactic approaches. PMID:24488049

    The myeloproliferative neoplasm, myelofibrosis (MF), has only one therapeutic intervention that is potentially curative in these individuals, specifically that of allogeneic stem cell transplantation (ASCT). ASCT has been utilized up to this juncture, primarily in younger individuals with higher risk disease. There is more limited data on outcomes in individuals over the age of 60 years. The choice of an individualized therapeutic intervention for a patient with MF is a very complex issue and is dependent on several factors. The first factor being their overall prognosis with their illness (which can vary from a median of 2 years in high-risk patients to over 10 years in low-risk patients) and the potential impact of a therapeutic intervention not only on survival but also on quality of life. Current available therapies have been strictly palliative for disease-associated anemia and/or splenomegaly. At present, we have a new generation of inhibitors of JAK2 (Ruxolitinib, CYT387, SB1518, TG101348, with others in development), which have been shown to improve splenomegaly, improve symptomatic burden of illness and improve quality of life. In addition, these inhibitors of JAK2 may have an impact on the natural history of MF, but confirmation of the presence and degree of this impact is still pending. Clinical availability of JAK2 inhibitors may alter the timing of transplant in marginal transplant candidates (that is, those over the age of 60), may have a role preceding ASCT to improve spleen size and performance status before transplant and might be frontline therapy in intermediate and high-risk patients who are not candidates for ASCT.

    Nephrotic syndrome (NS) is an extremely rare complication of myeloablative allogeneic haematopoietic cell transplantation (HCT) that usually occurs in association with chronic graft-versus-host disease (C-GVHD). We observed an unexpectedly high incidence of NS in a cohort of 163 consecutive patients undergoing non-myeloablative HCT from a related human leucocyte antigen-compatible donor. Seven patients developed NS at a median 318 d post-transplant (range 119-1203 d; cumulative incidence 6.1%). The median age at onset of NS was 46 years (range 33-59 years); three of the seven patients had no evidence of C-GVHD while four had accompanying limited C-GVHD. At diagnosis, median proteinuria was 16.5 g/24 h (range 3-24 g/24 h). Renal biopsy was performed in four cases and revealed membranous nephropathy. NS was not always associated with other symptoms of C-GVHD, and in contrast to previous reports, usually did not improve with the re-initiation of aggressive immunosuppression, resulting in progressive renal failure necessitating dialysis in three of seven cases. Membranous nephropathy resulting in NS is a previously unrecognised and clinically significant complication of non-myeloablative HCT. PMID:16173966

    Synopsis Myeloproliferative neoplasms (MPN), including primary myelofibrosis (PMF), polycythemia vera (PV), and essential thrombocythemia (ET) are clonal hematopoietic stem cell disorders. While some patients have an indolent course, all, to a lesser or greater extent, are at risk of progressing to severe marrow failure or of transforming into acute leukemia. Allogeneic hematopoietic cell transplantation (allo-HCT) is the only potential curative therapy. If transplantation is being considered and a suitable donor is available, allo-HCT should be carried out before leukemic transformation has occurred, as the prognosis is poor, even with allo-HCT, in patients who have evolved to leukemia. Survival following allo-HCT ranges from 30% to 70% at 5 years. The development of reduced-intensity conditioning regimens has allowed for successful allo-HCT even for older patients and patients with comorbid conditions. Results with high intensity/myeloablative (MAC) and reduced intensity conditioning (RIC) are comparable. Major pre-transplant risk factors for the outcome after allo-HCT are the disease stage of the MPN, the presence of comorbid conditions and the use of HLA non-identical donors. The pre-transplant use of JAK-2 inhibitors, which may be effective in down-staging a patient’s disease and decreasing comorbidities, may improve the outcomes following allo-HCT. Ongoing research is directed at determining the role of novel non-transplant strategies into the overall treatment algorithm. PMID:25459177

    Allogeneic blood transfusion (ABT) has been reported as a major risk factor for surgical site infection (SSI) in patients undergoing colorectal surgery. However, the association of ABT with SSI in patients undergoing abdominoperineal resection (APR) and total pelvic exenteration (TPE) still remains to be evaluated. Here, we aim to elucidate this association. The medical records of all patients undergoing APR and TPE at our institution in the period between January 2000 and December 2012 were reviewed. Patients without SSI (no SSI group) were compared with patients who developed SSI (SSI group), in terms of clinicopathologic features, including ABT. In addition, data for 262 patients who underwent transabdominal rectal resection at our institution in the same period were also enrolled, and their data on differential leukocyte counts were evaluated. Multivariate analysis showed that intraoperative transfusion was an independent predictive factor for SSI after APR and TPE (P = 0.004). In addition, the first-operative day lymphocyte count of patients undergoing APR, TPE, and transabdominal rectal resection was significantly higher in nontransfusion patients compared with transfusion ones (P = 0.026). ABT in the perioperative period of APR and TPE may have an important immunomodulatory effect, leading to an increased incidence of SSI. This fact should be carefully considered, and efforts to avoid allogeneic blood exposure while still achieving adequate patient blood management would be very important for patients undergoing APR and TPE as well.

    Allogeneic (allo) and autologous (auto) hematopoietic cell transplantation (HCT) provide the potential to cure otherwise fatal diseases but they are resource-intense therapies. There is scant literature describing the burden of hospital readmission in the critical 6-month period of immunosuppression after HCT. We report the incidence, causes, and outcomes of readmission in the 6 months after day 0 of HCT and in the 30 days after hospital discharge. This study is an institutional review board-approved retrospective medical record review of children who underwent HCT at a single institution. Between January 1, 2008 and December 31, 2011, 291 children underwent HCT at our institute. Of these, 140 patients were excluded because they were not followed primarily at our institute for the first 6 months after transplantation, 14 patients were excluded because they died during their initial hospitalization, and 1 patient was excluded because the initial hospitalization was longer than 6 months. Of the remaining 136 patients, 63% had at least 1 readmission. Of the patients who underwent allo-HCT, 78% were readmitted, in contrast to 38% of auto-HCT patients (P < .001). For the 206 readmissions, the mean length of hospital stay was 10.7 days (range, 1 to 129). Seventy-two percent of auto-HCT patients were initially readmitted for fever, and 46% ultimately had a source identified. No risk factors for readmission were found in the auto-HCT group. Fifty-two percent of allo-HCT patients were readmitted for fever and 28% of these patients ultimately had an identified source. Gastrointestinal-related problems accounted for 30% of primary readmissions among allo-HCT patients. Patients with an unrelated donor had a trend towards increased rates of 30-day readmission (P = .06) and were more likely to have a second readmission (P = .002). Patients who were cytomegalovirus (CMV) positive before transplantation were more likely to be readmitted (P = .02). The majority of children who

    A 44-year-old man (ASA-PS 1) underwent right lobectomy of the liver under total intravenous anesthesia with propofol, remifentanil, ketamine and rocuronium. In order to evade allogeneic blood transfusion, 1,200 g of the patient's blood was taken and hemodilution was induced for autologous blood transfusion (HAT) after the induction of anesthesia. As intraoperative blood loss amounted to about 4,000 g, Hb level decreased from 13.6 to 6.2 g x dl(-1). However, as intraoperative hemodynamics was relatively stable with crystalloidal and colloidal transfusion with no ischemic change on ECG and no metabolic acidosis, autologous blood transfusion was withheld. After returning the autologous blood, Hb increased to 9.8 g x dl(-1). Any postoperative complications related to the low Hb level were not recognized. HAT is a useful method to evade or at least decrease the amount of allogeneic blood transfusion by anesthesiologists. PMID:24558939

    Pediatric protocols for allogeneic hematopoietic SCT have been altered during the last two decades. To compare the outcomes in children (<18 yr old), who underwent SCT at our center during 1992-2002 (P1) and 2003-2013 (P2). We retrospectively analyzed 188 patients in P1 and 201 patients in P2. The most significant protocol changes during P2 compared with P1 were a decrease in MAC protocols, particularly those containing TBI, an increase in RIC protocols, and altered GvHD prophylaxis. In addition, P2 had more patients with nonmalignant diagnoses (p = 0.002), more mismatched (MM) donors (p = 0.01), and more umbilical CB grafts (p = 0.03). Mesenchymal or DSCs were used for severe acute GvHD during P2. Three-yr OS in P1 was 58%, and in P2, it was 78% (p < 0.001). Improved OS was seen in both malignant disorders (51% vs. 68%; p = 0.05) and nonmalignant disorders (77% vs. 87%; p = 0.04). Multivariate analysis showed that SCT during P2 was associated with reduced mortality (HR = 0.57; p = 0.005), reduced TRM (HR = 0.57; p = 0.03), unchanged relapse rate, similar rate of GF, less chronic GvHD (HR = 0.49; p = 0.01), and more acute GvHD (HR = 1.77, p = 0.007). During recent years, OS has improved at our center, possibly reflecting the introduction of less toxic conditioning regimens and a number of other methodological developments in SCT. PMID:27251184

    Relapse is least common in patients with indolent B-cell malignancies (iB-NHL) who undergo nonmyeloablative allogeneic transplantation (NMAT) in complete remission (CR). However, for the many patients unable to achieve this state, outcomes are poorly described and methods to improve results are unknown. We sought to describe the long-term follow-up and predictive factors for these poor-risk patients unable to achieve CR prior to NMAT. We identified and evaluated patients with iB-NHL including chronic lymphocytic leukemia (CLL) treated with fludarabine/total body irradiation-based NMAT that had evidence of persistent disease prior to NMAT. From December 1998 to April 2009, 89 patients were identified, most commonly with small lymphocytic lymphoma/CLL (N = 62) and follicular lymphoma (N = 24). Pretransplant anti-CD20 radioimmunotherapy (RIT) using standard yttrium-90-ibritumomab tiuxetan was administered to 18 (20%), who more frequently had chemoresistant disease (81% vs 39%, P = 0.003), disease bulk >5 cm (61% vs 15%, P <0.001), thrombocytopenia <25k/µL (33% vs 7%, P = 0.002), and Hematopoietic Cell Transplant Comorbidity Index scores of ≥3 (72% vs 37%, P = 0.006). After adjusting for these imbalances, RIT-treated patients had improved PFS (HR = 0.4, 95% CI: 0.2–0.9, P = 0.02) and OS (HR = 0.3, 95% CI: 0.1–0.8, P = 0.008) compared to the non-RIT group. The 3-year adjusted estimates of PFS and OS for the RIT and non-RIT groups were 71% and 87%, vs 44% and 59% (respectively). The use of RIT was the only factor independently associated with improved PFS and OS. Rates of non-relapse mortality and graft-versus-host disease (GVHD) were similar between the two groups, though over 70% of patients developed clinically-significant acute or chronic GVHD. In conclusion, despite relatively high rates of GVHD, patients with persistent iB-NHL can derive durable benefit from NMAT. PMID:25445025

    Reduced intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (HCT) with alemtuzumab, fludarabine, and melphalan is an effective approach for patients with nonmalignant disorders. Mixed chimerism and graft-versus-host-disease (GVHD) remain limitations on success. We hypothesized that higher levels of alemtuzumab at day 0 would result in a low risk of acute GVHD, a higher risk of mixed chimerism, and delayed early lymphocyte recovery and that alemtuzumab level thresholds for increased risks of these outcomes would be definable. We collected data from 105 patients to examine the influence of peritransplant alemtuzumab levels on acute GVHD, mixed chimerism, and lymphocyte recovery. The cumulative incidences of initial grades I-IV, II-IV, and III-IV acute GVHD in patients with alemtuzumab levels ≤0.15 vs ≥0.16 μg/mL were 68% vs 18% (P < .0001), 47% vs 13% (P = .0002), and 32% vs 8%, respectively (P = .005). The cumulative incidence of mixed chimerism in patients with an alemtuzumab level ≤0.15 μg/mL was 21%, vs 42% with levels of 0.16 to 4.35 μg/mL, and 100% with levels >4.35 μg/mL (P = .003). Patients with alemtuzumab levels ≤0.15 or 0.16 to 0.56 μg/mL had higher lymphocyte counts at day +30 and higher T-cell counts at day +100 compared with patients with levels ≥0.57 μg/mL (all P < .05). We conclude that peritransplant alemtuzumab levels impact acute GVHD, mixed chimerism, and lymphocyte recovery following RIC HCT with alemtuzumab, fludarabine, and melphalan. Precision dosing trials are warranted. We recommend a day 0 therapeutic range of 0.2 to 0.4 μg/mL. PMID:26644451

    Acute graft-versus-host disease (GVHD) results from the attack of host tissues by donor allogeneic T cells and is the most serious limitation of allogeneic hematopoietic cell transplantation (allo-HCT). Host antigen-presenting cells are thought to control the priming of alloreactive T cells and the induction of acute GVHD after allo-HCT. However, whereas the role of host DC in GVHD has been established, the contribution of host macrophages to GVHD has not been clearly addressed. We show that, in contrast to DC, reducing of the host macrophage pool in recipient mice increased donor T cell expansion and aggravated GVHD mortality after allo-HCT. We also show that host macrophages that persist after allo-HCT engulf donor allogeneic T cells and inhibit their proliferation. Conversely, administration of the cytokine CSF-1 before transplant expanded the host macrophage pool, reduced donor T cell expansion, and improved GVHD morbidity and mortality after allo-HCT. This study establishes the unexpected key role of host macrophages in inhibiting GVHD and identifies CSF-1 as a potential prophylactic therapy to limit acute GVHD after allo-HCT in the clinic.

    Although neurocognitive impairment has been established as a major issue among cancer survivors, the real-world consequences of this impairment are unclear. This study investigated the relationship between neurocognitive functioning and medication management ability over time among 58 patients treated with allogeneic hematopoietic stem cell transplantation (HCT). Participants completed a neuropsychological test battery and a simulated medication management task at three time points: pre-transplant (T0), Day 100 (T1) and 6 months post transplant (T2). Neurocognitively impaired participants performed worse on the medication management task than neurocognitively normal participants at each time point, and were more likely to score in the impaired range of medication management ability post transplant (72% vs 20%, P<0.001 at T1; 67% vs 23%, P=0.013 at T2). In multivariate analyses, worse performance in executive functioning/working memory consistently predicted impaired medication management ability, even when controlling for sociodemographic and clinical confounders (odds ratio=0.89, 95% confidence interval (0.80, 0.98), P=0.023). Lower physical symptom distress also predicted impaired medication management ability, but this effect decreased over time. Self-reported cognitive problems were not correlated with medication management ability at any time point. Findings suggest that poor neurocognitive functioning, particularly in the domain of executive functioning/working memory, is associated with worse medication management ability within the first 6 months after allogeneic HCT.

    Patients with chemorefractory non-Hodgkin lymphomas (NHL) generally have a poor prognosis. We used the observational database of the CIBMTR to study the outcome of 533 patients with refractory diffuse large B-cell lymphoma (DLBCL) or grade-III follicular lymphoma (FL-III) who underwent allogeneic transplantation (allo-HCT) using either myeloablative (MA; N=307) or reduced intensity/non-myeloablative conditioning (RIC/NST; N=226), between 1998-2010. We analyzed non-relapse mortality (NRM), relapse/progression, progression-free survival (PFS), and overall survival (OS). Only 45% of the patients at transplant had a Karnofsky performance score of ≥90%. Median follow-up of surviving patients after MA and RIC/NST allo-HCT is 35 months and 30 months, respectively. At 3years, MA allo-HCT was associated with a higher NRM compared to RIC/NST (53% vs. 42%; p=0.03), similar PFS (19% vs. 23%; p=0.40), and lower OS (19% vs. 28%; p=0.02), respectively. On multivariate analysis, FL-III histology was associated with lower NRM (relative-risk [RR]=0.52), reduced risk of relapse/progression (RR=0.42), superior PFS (RR=0.51) and OS (RR=0.53), while MA conditioning was associated with reduced risk of relapse/progression (RR=0.66). Despite a refractory state, a small subset of DLBCL and FL-III patients can attain durable remissions after allo-HCT. Conditioning regimen intensity was not associated with PFS and OS despite a higher risk of relapse/progression with RIC/NST allo-HCT. PMID:23380340

    Hematopoietic stem cell transplantation (HSCT) is curative for hematological manifestations of Fanconi anemia (FA). We performed a retrospective analysis of 22 patients with FA and aplastic anemia, myelodysplastic syndrome or acute myelogenous leukemia who underwent a HSCT at Memorial Sloan Kettering Cancer Center and survived at least 1 year post HSCT. Patients underwent either a TBI- (N=18) or busulfan- (N=4) based cytoreduction followed by T-cell-depleted transplants from alternative donors. Twenty patients were alive at time of the study with a 5- and 10-year overall survival of 100 and 84% and no evidence of chronic GvHD. Among the 18 patients receiving a TBI-based regimen, 11 (61%) had persistent hemochromatosis, 4 (22%) developed hypothyroidism, 7 (39%) had insulin resistance and 5 (27%) developed hypertriglyceridemia after transplant. Eleven of 16 evaluable patients (68%), receiving TBI, developed gonadal dysfunction. Two patients who received a TBI-based regimen died of squamous cell carcinoma. One patient developed hemochromatosis, hypothyroidism and gonadal dysfunction after busulfan-based cytoreduction. TBI appears to be a risk factor for malignant and endocrine late effects in the FA host. Multidisciplinary follow-up of patients with FA (including cancer screening) is essential for early detection and management of late complications, and improving long-term outcomes. PMID:26999465

    CALGB conducted a Phase II study to evaluate the safety and efficacy of a reduced-intensity conditioning regimen with allogeneic transplantation to treat patients with recurrent low grade B cell malignancies. Patients over age 18 with a diagnosis of relapsed, chemotherapy-sensitive disease underwent transplantation with a matched sibling donor and conditioning with cyclophosphamide (1 g/m2/d × 3) and fludarabine phosphate (25 mg/m2/d × 5). GVH prophylaxis included cyclosporine or tacrolimus plus low-dose methotrexate. Forty-four evaluable patients with a median age of 53 and median of two prior regimens were accrued. Sixteen patients had follicular NHL and 28 had histologies including 7 indolent B cell lymphomas, 4 mantle cell, 15 chronic lymphocytic leukemia, and 2 prolymphocytic leukemia pts. The six-month treatment-related mortality (TRM) was 2.4% and three-year TRM was 9%. Three-year event-free and overall survival were.75 and .81 for the follicular patients, .59 and .71 for the CLL/PLL patients, and .55 and .64 for the other histologies. The incidence of grade 2–4 acute graft vs host disease (GVHD) was 29% and extensive chronic GVHD was 18%. This report demonstrates that allogeneic sibling transplantation with a reduced intensity conditioning regimen is safe and efficacious for patients with advanced indolent B cell malignancies enrolled on a Cooperative Group study.

    In this retrospective study, 209 patients with malignant disease were analyzed for levels of T-cell receptor excision circles (TRECs) for the first 24 months after allogeneic stem cell transplantation. CD3(+) cells were separated by direct antibody-coupled magnetic beads, followed by DNA extraction according to a standard protocol. The δRec-ψJα signal joint TREC was measured with real-time quantitative PCR. Patients were grouped based on malignant disease: chronic myeloid leukemia, chronic lymphatic leukemia, acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), and myelodysplastic syndrome (MDS). Patients were further subdivided based on TREC levels below (low-TREC) or above (high-TREC) median at each time point. TREC levels were then correlated to relapse incidence and relapse-free survival (RFS). For patients with AML, low TREC levels 2 months post-transplantation were correlated to high relapse incidence at 5 years (P<0.05). In patients with chronic leukemia, high TREC levels were correlated with improved RFS (P<0.05). For patients with MDS, high TREC levels at 9 months post-transplantation were associated with higher RFS at 5 years (P<0.02) and lower relapse incidence (P<0.02). This study shows the potential use of TREC measurement in blood to predict relapse in patients with AML and MDS after allogeneic hematopoietic stem cell transplantation. PMID:24617310

    To evaluate if WT1 expression may predict relapse after allo-SCT, we analyzed WT1 levels on peripheral blood (PB) and bone marrow (BM) before and after allo-SCT in 24 AML patients with WT1 overexpression at diagnosis. Five copies of WT1/ABL × 104 from PB were identified as the threshold value that correlated with relapse after allo-SCT. The same correlation was not identified when WT1 expression was assessed from bone marrow (BM). Eight out of 11 (73%) patients with a pre-allo-SCT PB-WT1 ≥ 5 and 4/13 (31%) patients with a pre-allo-SCT PB-WT1 < 5 relapsed, respectively (P = 0.04). The incidence of relapse was higher in patients with PB-WT1 ≥ 5 measured after allo-SCT, at the 3rd (56% versus 38%; P = 0.43) and at the 6th month (71% versus 20%; P = 0.03). Patients with pretransplant PB-WT1 < 5 had significantly better 2-year OS and LFS than patients with a PB-WT1 ≥ 5 (81% versus 0% and 63% versus 20%) (P = 0.02). Our data suggest the usefulness of WT1 monitoring from PB to predict the relapse in allotransplanted AML patients and to modulate the intensity of conditioning and/or the posttransplant immunosuppression in an attempt to reduce the posttransplant relapse risk.

    To identify fall risks in patients undergoing hematopoietic stem cell transplantation (HSCT), the authors reviewed retrospective data on inpatients from April 2010 to March 2011. Among 77 HSCT patient records reviewed, the authors found that 35 patients had experienced at least one fall, including near-miss episodes (fallers). The main location of the falls was a corridor, and the main activity at the time of the fall was going to the toilet. To investigate fall risks along the HSCT time trajectory, the authors divided the time into pre- and post-engraftment periods and investigated the unique characteristics of each. PMID:25095291

    We treated patients under age 50 years with 131I-anti-CD45 antibody combined with fludarabine and 2 Gy total body irradiation to create an improved hematopoietic cell transplantation (HCT) strategy for advanced acute myeloid leukemia or high-risk myelodysplastic syndrome patients. Fifteen patients received 332–1,561 mCi of 131I, delivering an average of 27 Gy to bone marrow, 84 Gy to spleen, and 21 Gy to liver. Although a maximum dose of 28 Gy was delivered to the liver, no dose-limiting toxicity was observed. Marrow doses were arbitrarily capped at 43 Gy to avoid radiation-induced stromal damage; however no graft failure or evidence of stromal damage was observed. Twelve patients (80%) developed Grade II graft-versus-host disease (GVHD), one patient developed Grade III GVHD, and no patients developed Grade IV GVHD during the first 100 days after HCT. Of the 12 patients with chronic GVHD data, 10 developed chronic GVHD, generally involving the skin and mouth. Six patients (40%) are surviving after a median of 5.0 years (range, 4.2 to 8.3 years). The estimated survival at 1 year was 73% among the 15 treated patients. Eight patients relapsed, 7 of whom subsequently died. The median time to relapse among these 8 patients was 54 days (range, 26 to 1364 days). No cases of non-relapse mortality were observed in the first year after transplant. However, two patients died in remission from complications of chronic GVHD and cardiomyopathy, at 18 months and 14 months after transplant, respectively. This study suggests that patients may tolerate myeloablative doses >28 Gy delivered to the liver using 131I-anti-CD45 antibody in addition to standard reduced intensity conditioning. Moreover, the arbitrary limit of 43 Gy to the marrow may be unnecessarily conservative, and continued escalation of targeted radioimmunotherapy doses may be feasible to further reduce relapse.

    Posaconazole has been proven to be effective for antifungal prophylaxis in adults after hematopoietic stem cell transplantation (HSCT). Due to low gastrointestinal resorption of posaconazole suspension, bioavailability is impaired. Fatty food improves the uptake of posaconazole, but insufficient data on the pharmacokinetics of posaconazole in pediatric patients are available so far. The single-center analysis investigated 161 posaconazole serum concentrations in 27 pediatric patients after HSCT receiving 12 mg·kg BW(-1)·d(-1) posaconazole suspension depending on age, gender, and intestinal graft-versus-host (iGvHD) disease, and the influence of posaconazole on cyclosporine A plasma concentrations. To improve the uptake of posaconazole, one patient cohort received higher fat nutrition with the drug administration. A comparison of the regular nutrition and higher-fat nutrition groups revealed the following values: 31 (27.4%) versus 8 (16.7%) < 500 ng/ml; 12 (10.6%) versus 7 (14.6%) 500-700 ng/ml; 8 (7.1%) versus 6 (12.5%) 700-1000 ng/ml; 51 (45.1%) versus 21 (43.8%) 1000-2000 ng/ml; and 11 (9.7%) versus 6 (12.5%) > 2000 ng/ml. The mean posaconazole concentrations in patients with regular nutrition was 1123 ± 811 ng/ml and with higher-fat nutrition was 1191 ± 673 ng/ml. Posaconazole levels in patients with iGvHD were significantly lower (P = 0.0003) than in patients without GvHD. The majority of samples showed a sufficient posaconazole concentration above 700 ng/ml. Posaconazole levels were slightly higher in patients with higher-fat nutrition and significantly lower in patients with iGvHD. Cyclosporine A levels were not significantly higher during posaconazole administration. PMID:26483433

    Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative treatment option for myelodysplastic syndromes (MDS). Little is known about the prognostic impact of mutations, for example, in TP53 specifically after allo-HSCT. We here describe the prognostic impact of mutations in a panel of 19 genes analyzed by amplicon-based next-generation-sequencing in a uniformly treated patient cohort. Sixty-two patients with a median age of 61 yr suffered from MDS with 0-20% bone marrow blasts. International Prognostic Score was intermediate 1 (15%) and higher (79%). Conditioning uniformly was performed using a sequential approach in which FLAMSA chemotherapy was followed by Busulfan-based conditioning. Patients mostly were transplanted from an unrelated donor (77%), and 36% of patients received a graft from a mismatched donor. Median number of mutations was 2 (range 0-6). RUNX1, GATA2, TET2, and CEBPA were the genes most frequently found mutated. TP53, a factor previously reported to confer adverse prognostic impact after allogeneic stem cell transplantation, was mutated in samples from eight patients, one of which showed a silent mutation. With an estimated 5-yr overall/disease-free survival of 48 ± 7%/41 ± 7%, none of the mutations analyzed showed a prognostic impact in this analysis of the largest uniformly treated cohort thus far. This especially holds true for patients with a mutation in TP53. PMID:26680262

    From May, 1979 to March, 1981, 76 leukemia patients were prepared for bone marrow transplantation (BMT) with a new hyperfractionated total body irradiation (TBI) regimen (1320 cGy in 11 fractions, 3x/day), followed by cyclophosphamide, 60 mg/kg, for two days. Partial lung shielding was done on each treatment, with supplemental electron beam treatments of the chest wall to compensate, and of the testes, a sanctuary site. This regimen was initiated to potentially reduce fatal interstitial pneumonitis as well as decrease leukemic relapse. Overall actuarial survival at 1 year for acute non-lymphocytic leukemia (ANLL) patients is 63%, while relapse-free survival at 1 year is 53%. On the other hand, for acute lymphocytic leukemia (ALL) patients, there is no significant difference between relapse or remission patients with regard to overall survival or relapse-free survival, when relapse is defined as > 5% blasts in the marrow at the time of cytoreduction. Overall actuarial survival at 1 year for ALL is 61% and relapse-free survival is 45% at 1 year. Fatal interstitial pneumonitis has dropped to 18% compared with 50% in our previous single-dose TBI regimen (1000 cGy), in which the same doses of cyclophosphamide were given prior to TBI. In conclusion, not only has fatal interstitial pneumonitis been reduced by hyperfractionation and partial lung blocking, but there may be a survival advantage in ALL patients in relapse, who have a survival equal to that of remission patients. This may indicate a greater cell kill with the higher dose (1320 cGy) attained with this regimen, in these patients with a higher leukemic cell burden.

    The ideal outcome of allogeneic hematopoietic cell transplantation (allo-HCT) is based on survival that is free of morbidity. The most common causes of treatment failure and morbidity after HCT are relapse, graft-versus-host disease (GVHD), and nonrelapse death. A composite endpoint that measures survival free of clinically significant negative events may be a useful way to determine the success of allo-HCT. We assessed GVHD and relapse-free survival (GRFS) where the events were acute GVHD grades III to IV, chronic GVHD requiring immunosuppression, relapse, or death in 531 consecutive adult patients who received an allo-HCT between 2006 and 2014 at our center. Median follow-up of living patients was 46 months (range, 12 to 123). HLA matched related donor (MRD, n = 198, 37%), matched unrelated donor (MUD, n = 205, 39%), and haploidentical donor with post-transplant cyclophosphamide (HID, n = 128, 24%) were used. Thirty-six percent of patients had a high/very-high Dana Farber disease risk index (DRI). Estimated rates of GRFS at 1 and 2 years after MRD, MUD, and HID transplantations were 34% and 26%, 26% and 17%, and 33% and 31%, respectively, with MRD recipients having a better GRFS than MUD (P < .05). On multivariable analysis, peripheral blood stem cell source (HR, 1.34; P = .04), MUD (HR, 1.41; P = .003), and high/very high DRI (HR, 1.66; P = .001) were all associated with a worse GFRS post-HCT. These data suggest that GRFS can be predicted by patient disease risk, stem cell source, and donor type. Importantly, MUDs produce inferior GRFS to MRDs, whereas HIDs do not. PMID:27095692

    Myelodysplastic syndromes (MDS) comprise a heterogeneous group of clonal hematopoietic stem-cell disorders that result in varying degrees of cytopenia and risk of transformation into acute leukemia. Allogeneic stem-cell transplantation (SCT) is the only known cure for this disease. The treatment is routinely used for younger patients, but only a minority of patients older than the age of 60 undergo this procedure. The overall MDS incidence is 3.3 per 100,000, but the incidence in patients older than age 70 is between 15 and 50 per 100,000. The median age at presentation is 76 years. Medicare-age patients 65 or older represent 80% of the total population receiving an MDS diagnosis. In the United States, one of the obstacles to SCT for older patients with MDS has been lack of third party reimbursement. On August 4, 2010, the Centers for Medicare and Medicaid Services released their Decision Memo for Allogeneic Hematopoietic Stem Cell Transplantation (HSCT) for Myelodysplastic Syndrome. This memo states: “Allogeneic HSCT for MDS is covered by Medicare only for beneficiaries with MDS participating in an approved clinical study that meets the criteria below…. ” In this review, we will summarize what is known regarding the role of allogeneic SCT in older patients as well as other elements that should be included within clinical trials that can provide the evidence necessary to demonstrate that allogeneic SCT should be a covered benefit for Medicare beneficiaries.

    Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment for some hematologic malignancies. As the overall number of survivors continues to increase, studies systematically examining outcomes in long-term survivors are needed. We studied the clinical and quality-of-life outcomes in HSCT recipients surviving 5 or more years from HSCT. Since 1993, 262 patients with hematologic malignancies received a T cell-depleted myeloablative HSCT from an HLA-identical sibling at a single center. Ninety-two survived beyond 5 years from HSCT (median follow-up 9.4 years, range: 5.1-15.3). Median age at transplantation was 35 years (range: 10-56). Twenty-two (24%) received a bone marrow transplant, and 70 (76%) received a peripheral blood HSCT. Of the 92 survivors, 60 completed quality-of-life measures. The main outcomes examined were chronic graft-versus-host-disease, disease relapse, survival, health-related quality-of-life (HRQL) (Functional Assessment of Cancer Therapy-General), physical and mental health (SF-36), and symptom experience (Rotterdam Symptom Checklist). Seventy-five (82%) of 92 survivors no longer required systemic immunosuppressive treatment. Four (4.3%) relapsed with leukemia at a median of 8.5 years (range: 6.2-14.0) after HSCT. Four (4.3%) died between 7.4 and 13.4 years post-HSCT (1 relapse, 1 lung cancer, 1 pneumonia, 1 brain hemorrhage). Most survivors beyond 5 years had an excellent performance status with no difference in physical and mental health and higher HRQL scores (P = .02) compared with population norms. Although physical and psychologic symptom distress was low, those with higher symptom distress experienced inferior HRQL. These results show that 5 or more years after T cell-depleted HSCT for hematologic malignancy most individuals survive disease free with an excellent performance status, preserved physical and psychological health, and excellent HRQL.

    Insulin independence after islet transplantation has been significantly improved by using new steroid-free immunosuppressive protocols and increased islet mass. Only little is known about the influence on the morphology of the liver of intraportally transplanted islets. We describe a case of disseminated periportal fatty degeneration after allogeneic intraportal islet transplantation (ITx). A 35-year-old patient with type-1 diabetes mellitus who was suffering from repeated severe hypoglycemic episodes received two sequential intraportal islet grafts. Liver structure was normal before the first ITx, based upon ultrasound and magnetic resonance imaging (MRI). One week after the first ITx, ultrasound demonstrated normal liver morphology. Four months later, at the second ITx, we detected small, disseminated, and hypodense hepatic lesions (1 to 3 mm) by ultrasound, which were confirmed by MRI and interpreted to be fatty degenerations. Histologically we found focal drop-shaped fatty degenerations with signs of mild periportal chronic inflammation. These liver alterations without clinical symptoms or pathological liver function tests matched the predicted distribution of infused islets. Glucose metabolism markedly improved after the first ITx, namely 58.6% reduction of daily insulin requirements, 1.4% decrease in HbA1c, basal C-peptide of 0.8 to 1.3 ng/dl with no severe hypoglycemia. We interpreted these benign changes in liver morphology as reactions to a local hyperinsulinemia in the neighborhood of the transplanted islets. We hypothesized that a steroid-free immunosuppression with rapamycin and tacrolimus may have contributed to changes in the portal microenvironment. PMID:15194387

    Described herein is a first-in-man attempt to both genetically modify T cells with an imagable suicide gene and track these transduced donor T cells in allogeneic stem cell transplantation recipients using noninvasive positron emission tomography/computerized tomography (PET/CT) imaging. A suicide gene encoding a human CD34-Herpes Simplex Virus-1-thymidine kinase (CD34-TK75) fusion enabled enrichment of retrovirally transduced T cells (TdT), control of graft-versus-host disease and imaging of TdT migration and expansion in vivo in mice and man. Analysis confirmed that CD34-TK75-enriched TdT contained no replication competent γ-retrovirus, were sensitive to ganciclovir, and displayed characteristic retroviral insertion sites (by targeted sequencing). Affinity-purified CD34-TK75+-selected donor T cells (1.0–13 × 105)/kg were infused into eight patients who relapsed after allogeneic stem cell transplantation. Six patients also were administered 9-[4-(18F)fluoro-3-hydroxymethyl-butyl]guanine ([18F]FHBG) to specifically track the genetically modified donor T cells by PET/CT at several time points after infusion. All patients were assessed for graft-versus-host disease, response to ganciclovir, circulating TdT cells (using both quantitative polymerase chain reaction and [18F]FHBG PET/CT imaging), TdT cell clonal expansion, and immune response to the TdT. This phase 1 trial demonstrated that genetically modified T cells and [18F]FHBG can be safely infused in patients with relapsed hematologic malignancies after allogeneic stem cell transplantation.

    Early detection of subclinical lung function decline may help identify allogeneic hematopoietic cell transplant (HCT) recipients who are at increased risk for late noninfectious pulmonary complications, including bronchiolitis obliterans syndrome. We evaluated the use of handheld spirometry in this population. Allogeneic HCT recipients enrolled in a single-center observational trial performed weekly spirometry with a handheld spirometer for 1 year after transplantation. Participants performed pulmonary function tests in an outpatient laboratory setting at 3 time points: before transplantation, at day 80 after transplantation, and at 1 year after transplantation. Correlation between the 2 methods was assessed by Pearson and Spearman correlations; agreement was assessed using Bland-Altman plots. A total of 437 subjects had evaluable pulmonary function tests. Correlation for forced expiratory volume in 1 second (FEV1) was r = .954 (P < .0001) at day 80 and r = .931 (P < .0001) at 1 year when the handheld and laboratory tests were performed within 1 day of each other. Correlation for handheld forced expiratory volume in 6 seconds (FEV6) with laboratory forced vital capacity was r = .914 (P < .0001) at day 80 and r = .826 (P < .0001) at 1 year. The bias, or the mean difference (handheld minus laboratory), for FEV1 at day 80 and 1 year was -.13 L (limits of agreement, -.63 to .37) and -.10 L (limits of agreement, -.77 to .56), respectively. FEV6 showed greater bias at day 80 (-.51 L [limits of agreement, -1.44 to .42]) and 1 year (-.40 L [limits of agreement, -1.81 to 1.01]). Handheld spirometry correlated well with laboratory spirometry after allogeneic HCT and may be useful for self-monitoring of patients for early identification of airflow obstruction.

    Background/Aims BK virus (BKV) has been associated with late-onset hemorrhagic cystitis (HC) in recipients of hematopoietic stem cell transplantation (HSCT). Cidofovir has been used at higher doses (3 to 5 mg/kg/wk) with probenecid prophylaxis; however, cidofovir may result in nephrotoxicity or cytopenia at high doses. Methods Allogeneic HSCT recipients with BKV-associated HC are treated with 1 mg/kg intravenous cidofovir weekly at our institution. A microbiological response was defined as at least a one log reduction in urinary BKV viral load, and a clinical response was defined as improvement in symptoms and stability or reduction in cystitis grade. Results Eight patients received a median of 4 weekly (range, 2 to 11) doses of cidofovir. HC occurred a median 69 days (range, 16 to 311) after allogeneic HSCT. A clinical response was detected in 7/8 patients (86%), and 4/5 (80%) had a measurable microbiological response. One patient died of uncontrolled graft-versus-host disease; therefore, we could not measure the clinical response to HC treatment. One microbiological non-responder had a stable BKV viral load with clinical improvement. Only three patients showed transient grade 2 serum creatinine toxicities, which resolved after completion of concomitant calcineurin inhibitor treatment. Conclusions Weekly intravenous low-dose cidofovir without probenecid appears to be a safe and effective treatment option for patients with BKV-associated HC. PMID:25750563

    Survival of patients ≥40 years of age with Philadelphia-negative acute lymphoblastic leukemia (ALL) remains poor with current therapeutic approaches. It is unknown whether allogeneic hematopoietic stem-cell transplantation (HSCT) in first remission confers a survival benefit compared to a chemotherapy-only approach. We retrospectively compared the outcome of patients >40 years treated with HSCT or chemotherapy alone in first remission (n = 40 in each cohort). Three-year overall survival (OS) and disease-free survival (DFS) were not significantly different between the chemotherapy-only and HSCT groups (OS, 46% [31-68] vs. 40% [27-59], P = 0.35; DFS, 31% [18-52] vs. 40% [27-59], P = 0.98). The 3-year cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) were 61% [41-76] and 9% [2-21] for the chemotherapy-only group and 28% [15-43] and 32% [17-47] for the transplant group (CIR, P = 0.011; NRM, P = 0.014). Allogeneic transplantation for patients ≥40 years with Ph-negative ALL in first remission is associated with a lower CIR, but this benefit is offset by considerable NRM as compared with chemotherapy-only approach. HSCT may be beneficial in patients with high-risk disease features. Am. J. Hematol. 91:793-799, 2016. © 2016 Wiley Periodicals, Inc. PMID:27153389

    In this study we compared the lymphocyte reconstitution in 13 multiple myeloma (MM), nine acute myeloid leukemia (AML) and 10 chronic myeloid leukemia (CML) patients after allogeneic G-CSF-mobilized PBSC transplantation from HLA-identical siblings. Conditioning regimens included standard total body irradiation + cyclophosphamide (CY), or busulphan + CY, whereas VP-16 was added in patients with advanced disease. Overall comparable numbers of mononuclear cells, CD34+ cells and CD3+ T cells were infused in each group. A significantly higher CD3+ T cell number was observed in MM and AML than in CML patients 1 month after transplant. However, MM patients showed a faster and better recovery of CD4+ T cells than both AML and CML patients at 3 months (P = 0.01 and P = 0.01, respectively) and 12 months (P = 0.01 vs AML, while P = NS vs CML) after transplant, and had a CD4:CD8 ratio > 1 with a median CD4+ T cell value > 400/microl 1 year after transplant. Development of acute graft-versus-host disease (GVHD) did not affect CD4:CD8 ratios but patients who experienced acute GVHD > grade I had lower CD4+ and CD8+ T cell numbers at all time points. However, after excluding patients with GVHD > grade I, MM patients still showed a significantly higher CD4+ T cell value than patients with myeloproliferative diseases 1 year after transplant. These findings suggest that although allogeneic PBSC transplantation induces rapid immune reconstitution, different kinetics may occur among patients with hematological malignancies. In particular, the rapid reconstitution of CD4+ T cells in MM patients may contribute to the low transplant-related mortality achieved in this disease. PMID:11223973

    We sought to assess the late mortality risks and causes of death among long-term survivors of allogeneic hematopoietic stem cell transplantation (HCT). The cases of 11,047 relapse-free survivors of a first HCT at least 2 years after HCT were analyzed. Standardized mortality ratios (SMR) were calculated and specific causes of death were compared with those of the Japanese population. Among relapse-free survivors at 2 years, overall survival percentages at 10 and 15 years were 87% and 83%, respectively. The overall risk of mortality was significantly higher compared with that of the general population. The risk of mortality was significantly higher from infection (SMR = 57.0), new hematologic malignancies (SMR = 2.2), other new malignancies (SMR = 3.0), respiratory causes (SMR = 109.3), gastrointestinal causes (SMR = 3.8), liver dysfunction (SMR = 6.1), genitourinary dysfunction (SMR = 17.6), and external or accidental causes (SMR = 2.3). The overall annual mortality rate showed a steep decrease from 2 to 5 years after HCT; however, the decrease rate slowed after 10 years but was still higher than that of the general population at 20 years after HCT. SMRs in the earlier period of 2 to 4 years after HCT and 5 years or longer after HCT were 16.1 and 7.4, respectively. Long-term survivors after allogeneic HCT are at higher risk of mortality from various causes other than the underlying disease that led to HCT. Screening and preventive measures should be given a central role in reducing the morbidity and mortality of HCT recipients on long-term follow-up. PMID:27246369

    In patients with relapsed or refractory (r/r) acute myeloid leukemia (AML), long-term disease control can only be achieved by allogeneic hematopoietic stem cell transplantation (HSCT). We studied the safety and efficacy of clofarabine-based salvage therapy. The study was designed as phase II, multicenter, intent-to-transplant (ITT) study. A total of 84 patients with r/r AML were enrolled. All patients received at least one cycle of CLARA (clofarabine 30 mg/m(2) and cytarabine 1 g/m(2), days 1-5). Chemo-responsive patients with a donor received HSCT in aplasia after first CLARA. Generally, HSCT was performed as soon as possible. The conditioning regimen consisted of clofarabine (4 × 30 mg/m(2)) and melphalan (140 mg/m(2)). The median patient age was 61 years (range 40-75). On day 15 after start of CLARA, 26% of patients were in a morphologically leukemia-free state and 79% exposed a reduction in bone marrow blasts. Overall, 67% of the patients received HSCT within the trial. The primary end point, defined as complete remission after HSCT, was achieved by 60% of the patients. According to the ITT, overall survival at 2 years was 43% (95% confidence interval (CI), 32-54%). The 2-year disease-free survival for transplanted patients was 52% (95% CI, 40-69%). Clofarabine-based salvage therapy combined with allogeneic HSCT in aplasia shows promising results in patients with r/r AML. PMID:26283567

    Allogeneic hematopoietic cell transplantation (HCT) is an effective treatment for adult T-cell leukemia (ATL), raising the question about the role of graft-versus-leukemia effect against ATL. In this study, we retrospectively analyzed the effects of acute and chronic graft-versus-host disease (GVHD) on overall survival, disease-associated mortality, and treatment-related mortality among 294 ATL patients who received allogeneic HCT and survived at least 30 days posttransplant with sustained engraftment. Multivariate analyses treating the occurrence of GVHD as a time-varying covariate demonstrated that the development of grade 1-2 acute GVHD was significantly associated with higher overall survival (hazard ratio [HR] for death, 0.65; P = .018) compared with the absence of acute GVHD. Occurrence of either grade 1-2 or grade 3-4 acute GVHD was associated with lower disease-associated mortality compared with the absence of acute GVHD, whereas grade 3-4 acute GVHD was associated with a higher risk for treatment-related mortality (HR, 3.50; P < .001). The development of extensive chronic GVHD was associated with higher treatment-related mortality (HR, 2.75; P = .006) compared with the absence of chronic GVHD. Collectively, these results indicate that the development of mild-to-moderate acute GVHD confers a lower risk of disease progression and a beneficial influence on survival of allografted patients with ATL.

    Minimal residual disease (MRD) was monitored by Wilms tumor 1 (WT1) expression in 207 patients with acute myeloid leukemia (AML) after an allogeneic hemopoietic stem cell transplantation (HSCT) as a trigger to initiate pre-emptive immunotherapy (IT) with cyclosporin discontinuation and/or donor lymphocyte infusion. The trigger for IT was WT1 ≥ 180 copies/10(4) Abelson cells in marrow cells in the first group of 122 patients (WT1-180) and ≥ 100 copies in a subsequent group of 85 patients (WT1-100). Forty patients received IT. The cumulative incidence (CI) of relapse was 76% in WT1-180 (n = 17) versus 29% in WT1-100 patients (n = 23) receiving IT (P = .006); the leukemia-free survival from MRD positivity was 23% versus 74%, respectively (P = .003). We then looked at the entire AML patient population (n = 207). WT1-180 and WT1-100 patients were comparable for disease phase and age. The overall 4-year CI of transplantation-related mortality was 13% in both groups; the CI of leukemia relapse was 38% in the WT1-180 and 28% in the WT1-100 patients (P = .05) and leukemia-free survival was 56% versus 48%, respectively (P = .07). In conclusion, we suggests that WT1-based pre-emptive immunotherapy is feasible in patients with undergoing an allogeneic HSCT. The protective effect on relapse is greater when IT is triggered at lower levels of WT1. PMID:26970379

    Allogeneic stem cell transplantation is commonly used in the treatment of younger patients with severe hematological diseases, and endothelial cells seem to be important for the development of several posttransplant complications. Capillary leak syndrome is a common early posttransplant complication where endothelial cell dysfunction probably contributes to the pathogenesis. In the present study we investigated whether the pretreatment serum metabolic profile reflects a risk of posttransplant capillary leak syndrome. We investigated the pretransplant serum levels of 766 metabolites for 80 consecutive allotransplant recipients. Patients with later capillary leak syndrome showed increased pretherapy levels of metabolites associated with endothelial dysfunction (homocitrulline, adenosine) altered renal regulation of fluid and/or electrolyte balance (betaine, methoxytyramine, and taurine) and altered vascular function (cytidine, adenosine, and methoxytyramine). Additional bioinformatical analyses showed that capillary leak syndrome was also associated with altered purine/pyrimidine metabolism (i.e., metabolites involved in vascular regulation and endothelial functions), aminoglycosylation (possibly important for endothelial cell functions), and eicosanoid metabolism (also involved in vascular regulation). Our observations are consistent with the hypothesis that the pretransplant metabolic status can be a marker for posttransplant abnormal fluid and/or electrolyte balance. PMID:26609191

    To study the efficacy of sorafenib to prevent relapse in patients with FLT3-ITD mutation positive acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). A total of 7 cases with FLT3-ITD positive AML have received allo-HSCT in our department from May 2013 to January 2015. Six cases were administrated with sorafenib after hematopoietic reconstruction. Another patient relapsed on day 192 past allo-HSCT, then she started to use sorafenib after remission of re-induction regimens. Five patients survived. The median progression free survival was 280(126-366)day. This study suggests that sorafenib might prevent relapse past allo-HSCT and improve survival in patients with FLT3-ITD positive AML.

    Delayed reconstitution of the T cell compartment in recipients of allogeneic stem cell grafts is associated with an increase of reactivation of latent viruses. Thereby, the transplanted T cell repertoire appears to be one of the factors that affect T cell reconstitution. Therefore, we studied the T cell receptor beta (TCRβ) gene rearrangements of flow cytometry–sorted CD4+ and CD8+ T cells from the peripheral blood of 23 allogeneic donors before G-CSF administration and on the day of apheresis. For this purpose, TCRβ rearrangements were amplified by multiplex PCR followed by high-throughput amplicon sequencing. Overall, CD4+ T cells displayed a significantly higher TCRβ diversity compared to CD8+ T cells irrespective of G-CSF administration. In line, no significant impact of G-CSF treatment on the TCR Vβ repertoire usage was found. However, correlation of the donor T cell repertoire with clinical outcomes of the recipient revealed that a higher CD4+ TCRβ diversity after G-CSF treatment is associated with lower reactivation of cytomegalovirus and Epstein–Barr virus. By contrast, no protecting correlation was observed for CD8+ T cells. In essence, our deep TCRβ analysis identifies the importance of the CD4+ T cell compartment for the control of latent viruses after allogeneic stem cell transplantation. PMID:25873100

    HLA-G is a non-classical MHC class I molecule whose suppressive activity on immune effector cells is exerted due to interactions with receptors ILT2, ILT4 and KIR2DL4. These receptors are expressed mainly on NK cells and monocytes, and their intensity of expression changes depending on HLA-G level. HLA-G plays an important role in the development of tolerance following organ transplantations and bone marrow stem cell transplantations. HLA-G also participates in the modulation of the immune response during cancerogenesis. The aim of this study was to assess HLA-G level in blood serum, the percentage of NK cells and monocytes with expression of receptors for HLA-G (ILT2, ILT4, KIR2DL4 and NKG2D) in patients who received allogeneic stem cell transplantations, and their influence on the occurrence of graft-versus-host reaction. The study included 32 patients with bone marrow diseases (acute leukemias, myelodysplastic syndrome, chronic myeloid leukemia, paroxysmal nocturnal hemoglobinuria) who received allogeneic stem cell transplantations. We assessed the expression of receptors ILT2, ILT4, KIR2DL4 and NKG2D on monocytes and NK cells, as well as the level of HLA-G in blood serum in patients before conditioning, in the transplant hematopoietic reconstitution period following allogeneic bone marrow stem cell transplantation. The percentage of NK cells with expression of KIR2DL4, ILT2 and ILT4 receptors was higher in patients with 0-I grade GVHD than in patients with II-IV grade GVHD. The percentage of monocytes with expression of ILT4 and ILT2 receptors was higher in patients with 0-I grade GVHD than in patients with II-IV grade GVHD. The level of HLA-G in patients' blood serum was higher after the stem cell transplantation compared with the period before transplantation. HLA-G level and HLA-G receptors are related to intensity of GVHD and may play the role of a prognostic factor for the development of GVHD and the clinical course of this reaction. PMID:26187179

    We examined the course and the prevalence of a high fear of cancer recurrence (FCR) in patients undergoing allogeneic PBSC transplantation (hematopoietic SCT (HSCT)) before HSCT (N=239), 100 days after (n=150, and 12 months after allogeneic HSCT (n=102). The Fear of Progression Questionnaire-Short Form (FoP-Q-SF), the EORTC Quality of Life Questionnaire, and the Hospital Anxiety and Depression Scale were used. Pre-HSCT 36% of patients, 100 days after HSCT 24% of patients, and 1 year after HSCT 23% of patients fulfilled the criteria for high FCR (FoP-Q-SF cutoff=34). Being married (b=2.76, P=0.026), female gender (b=4.45, P<0.001) and depression (b=4.44, P<0.001) were significantly associated with FCR at baseline. One hundred days after HSCT, depression significantly predicted FCR (b=6.46, P<0.001). One year following HSCT, female gender (b=6.61, P=0.008) and higher depression were (b=4.88, P=0.004) significant predictors for FCR. Over the three assessment points, patients with high FCR had a significantly lower quality of life compared to patients with low FCR in physical functioning (P=0.019), role functioning (P=0.003), emotional functioning (P<0.001), cognitive functioning (P=0.003), social functioning (P<0.001) and global quality of life (P<0.001). Our data provide evidence that FCR is a prevalent problem in patients with hematological malignancies and has a significant adverse impact on health-related quality of life. PMID:25000458

    Although hematopoietic cell transplantation (HCT) is the only curative therapy for many advanced hematologic cancers, little is known about the financial hardship experienced by HCT patients nor the association of hardship with patient-reported outcomes. We mailed a 43-item survey to adult patients approximately 180 days after their first autologous or allogeneic HCT at 3 high-volume centers. We assessed decreases in household income; difficulty with HCT-related costs, such as need to relocate or travel; and 2 types of hardship: hardship_1 (reporting 1 or 2 of the following: dissatisfaction with present finances, difficulty meeting monthly bill payments, or not having enough money at the end of the month) and "hardship_2" (reporting all 3). Patient-reported stress was measured with the Perceived Stress Scale-4, and 7-point scales were provided for perceptions of overall quality of life (QOL) and health. In total, 325 of 499 surveys (65.1%) were received. The median days since HCT was 173; 47% underwent an allogeneic HCT, 60% were male, 51% were > 60 years old, and 92% were white. Overall, 46% reported income decline after HCT, 56% reported hardship_1, and 15% reported hardship_2. In multivariable models controlling for income, those reporting difficulty paying for HCT-related costs were more likely to report financial hardship (odds ratio, 6.9; 95% confidence interval, 3.8 to 12.3). Hardship_1 was associated with QOL below the median (odds ratio, 2.9; 95% confidence interval, 1.7 to 4.9), health status below the median (odds ratio, 2.2; 95% confidence interval, 1.3 to 3.6), and stress above the median (odds ratio, 2.1; 95% confidence interval, 1.3 to 3.5). In this sizable cohort of HCT patients, financial hardship was prevalent and associated with worse QOL and higher levels of perceived stress. Interventions to address patient financial hardship-especially those that ameliorate HCT-specific costs-are likely to improve patient-reported outcomes. PMID:27184627

    Patients with hematological malignancies were conditioned using a rabbit anti-thymocyte globulin based reduced intensity conditioning regimen for allogeneic stem cell transplantation (SCT). Donor-derived CD3+ cell count (ddCD3), a product of CD3+ cell chimerism and absolute CD3+ cell count, when less than 110/μL, eight weeks post-transplant, predicted a high risk of sustained mixed chimerism and relapse. Alternatively, patients with a higher ddCD3 developed GVHD more frequently, and when partially chimeric, had higher rates of conversion to full donor chimerism upon withdrawal of immunosuppression. In conclusion, early data from a small cohort of patients indicates that ddCD3+ cell count at 8 weeks may be used to guide the decision-making process regarding withdrawal of immunosuppression and administration of donor lymphocyte infusion in partially T cell depleted reduced intensity regimens.

    Background Transfusion-dependency affects the natural history of myelodysplastic syndromes. Secondary iron overload may concur to this effect. The relative impact of these factors on the outcome of patients with myelodysplastic syndrome receiving allogeneic stem-cell transplantation remains to be clarified. Design and Methods We retrospectively evaluated the prognostic effect of transfusion history and iron overload on the post-transplantation outcome of 357 patients with myelodysplastic syndrome reported to the Gruppo Italiano Trapianto di Midollo Osseo (GITMO) registry between 1997 and 2007. Results Transfusion-dependency was independently associated with reduced overall survival (hazard ratio=1.48, P=0.017) and increased non-relapse mortality (hazard ratio=1.68, P=0.024). The impact of transfusion-dependency was noted only in patients receiving myeloablative conditioning (overall survival: hazard ratio=1.76, P=0.003; non-relapse mortality: hazard ratio=1.70, P=0.02). There was an inverse relationship between transfusion burden and overall survival after transplantation (P=0.022); the outcome was significantly worse in subjects receiving more than 20 red cell units. In multivariate analysis, transfusion-dependency was found to be a risk factor for acute graft-versus-host disease (P=0.04). Among transfusion-dependent patients undergoing myeloablative allogeneic stem cell transplantation, pre-transplantation serum ferritin level had a significant effect on overall survival (P=0.01) and non-relapse mortality (P=0.03). This effect was maintained after adjusting for transfusion burden and duration, suggesting that the negative effect of transfusion history on outcome might be determined at least in part by iron overload. Conclusions Pre-transplantation transfusion history and serum ferritin have significant prognostic value in patients with myelodysplastic syndrome undergoing myeloablative allogeneic stem cell transplantation, inducing a significant increase of non

    Little is known about how patients undergoing hematopoietic stem cell transplantation (HCT) and their family caregivers (FC) perceive their prognosis. We examined prognostic understanding in patients undergoing HCT and their FC and its relationship with quality of life (QOL) and mood. We conducted a longitudinal study of patients (and FC) hospitalized for HCT. We used a questionnaire to measure participants' prognostic understanding and asked the oncologists to estimate patients' prognosis prior to HCT. We assessed QOL and mood weekly and evaluated the relationship between prognostic understanding, and QOL and mood using multivariable linear mixed models. We enrolled 90 patients undergoing (autologous (n=30), myeloablative (n=30) or reduced intensity allogeneic (n=30)) HCT. About 88.9% of patients and 87.1% of FC reported it is 'extremely' or 'very' important to know about prognosis. However, 77.6% of patients and 71.7% of FC reported a discordance and more optimistic prognostic perception compared to the oncologist (P<0.0001). Patients with a concordant prognostic understanding with their oncologists reported worse QOL (β=-9.4, P=0.01) and greater depression at baseline (β=1.7, P=0.02) and over time ((β=1.2, P<0.0001). Therefore, Interventions are needed to improve prognostic understanding, while providing patients with adequate psychological support. PMID:25961772

    The maximum age of patients receiving allogeneic hematopoietic stem cell transplantation (alloHCT) has been moving up over time. However, the availability of a suitable HLA-matched sibling donor may limit access of this patient population to alloHCT. We retrospectively investigated the outcomes of umbilical cord blood transplantation (UCBT) after reduced-intensity conditioning regimens in patients aged ≥70 years with myelodysplastic syndrome (MDS) and acute myelogenous leukemia (AML) between 2010 and 2014. During this period 70 patients with AML/MDS were referred to our center for alloHCT consideration. Twenty-two patients (33%) received alloHCT: 10 UCBT, 9 HLA full-matched sibling donor transplantation, 2 haploidentical alloHCT, and 1 unrelated donor alloHCT. In UCBT, cumulative incidences of nonrelapse mortality and relapse were 20% and 30% at 2 years, respectively. The cumulative incidence of acute graft-versus-host disease (GVHD) at day +100 and chronic GVHD at 2 years was 10%. Seven patients had viral reactivation/infections. Rates of overall survival and disease-free survival were 60% and 50% at 2 years, respectively. Moreover, these outcomes seemed to be similar to that of patients aged 60 to 69 years receiving UCBT (n = 60) and patients aged ≥70 years receiving HLA full-matched sibling donor transplantation (n = 9). These results suggest that UCBT is feasible in selected AML/MDS patients aged ≥70 years. In fact, UCBT shortens the required time for an unrelated donor search and thus increases the chance of proceeding with alloHCT, which might contribute to higher rates of alloHCT in the referral group. Outcomes of UCBT are promising; however, larger studies with a longer follow-up are needed. PMID:26415559

We enrolled 90 patients undergoing (autologous n=30); myeloablative (n=30) or reduced intensity allogeneic (n=30)) HCT. 88.9% of patients and 87.1% of FC reported it is ‘extremely’ or ‘very’ important to know about prognosis. However, 77.6% of patients and 71.7% of FC reported a discordance and more optimistic prognostic perception compared to the oncologist (P’s < 0.0001). Patients with a concordant prognostic understanding with their oncologists reported worse QOL (β = −9.4, P = 0.01) and greater depression at baseline (β = 1.7, P = 0.02) and over time ((β = 1.2, P < 0.0001). Therefore, Interventions are needed to improve prognostic understanding, while providing patients with adequate psychological support. PMID:25961772

    We examined current outcomes of unrelated donor allogeneic hematopoietic cell transplantation (HCT) to determine the clinical implications of donor-recipient HLA matching. Adult and pediatric patients who had first undergone myeloablative-unrelated bone marrow or peripheral blood HCT for acute myelogenous leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, and myelodysplastic syndrome between 1999 and 2011 were included. All had high-resolution typing for HLA-A, -B, -C, and -DRB1. Of the total (n = 8003), cases were 8/8 (n = 5449), 7/8 (n = 2071), or 6/8 (n = 483) matched. HLA mismatch (6-7/8) conferred significantly increased risk for grades II to IV and III to IV acute graft vs host disease (GVHD), chronic GVHD, transplant-related mortality (TRM), and overall mortality compared with HLA-matched cases (8/8). Type (allele/antigen) and locus (HLA-A, -B, -C, and -DRB1) of mismatch were not associated with overall mortality. Among 8/8 matched cases, HLA-DPB1 and -DQB1 mismatch resulted in increased acute GVHD, and HLA-DPB1 mismatch had decreased relapse. Nonpermissive HLA-DPB1 allele mismatch was associated with higher TRM compared with permissive HLA-DPB1 mismatch or HLA-DPB1 match and increased overall mortality compared with permissive HLA-DPB1 mismatch in 8/8 (and 10/10) matched cases. Full matching at HLA-A, -B, -C, and -DRB1 is required for optimal unrelated donor HCT survival, and avoidance of nonpermissive HLA-DPB1 mismatches in otherwise HLA-matched pairs is indicated.

    The factors that influence utilization of reduced-intensity conditioning (RIC) allogeneic hematopoietic stem cell transplantation (HCT) among medically fit older patients with advanced myelodysplastic syndromes (MDS) are largely unknown. The MDS Transplant-Associated Outcomes (MDS-TAO) study is an ongoing prospective observational study at the Dana-Farber Cancer Institute and Massachusetts General Hospital that enrolls transplant-eligible fit patients aged 60-75 years with advanced MDS and follows them through RIC HCT vs non-HCT treatment. In this analysis of 127 patients enrolled from May 2011 to June 2014, we examined the influence of age, gender, cytogenetics, International Prognostic Scoring System (IPSS) category, performance status, distance from HCT center and baseline patient-reported quality of life (QOL) from the EORTC QLQ-C30 (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire) on the likelihood of receiving RIC HCT using competing risk regression modeling. With a median follow-up of 16 months, 44 patients (35%) had undergone RIC HCT. In multivariable analyses, age (hazard ratio (HR) 0.87 per year, 95% confidence interval (CI): 0.81-0.92, P<0.001) and higher IPSS (intermediate-2/high; HR 2.29, 95% CI: 1.25-4.19, P=0.007) were significantly predictive of receipt of RIC HCT; neither global QOL score nor any QOL subscales scores were predictive. These data suggest that baseline patient-reported QOL has little influence on the decision to undergo RIC HCT for older patients with advanced MDS. PMID:26999469

    Outcomes of patients with acute myeloid leukemia (AML) who are refractory to high-dose Cytarabine (HiDAC)-based induction are dismal. Allogeneic hematopoietic stem cell transplantation (AHSCT) as initial salvage may be effective and potentially superior to conventional salvage chemotherapy. Eighteen percent (285 of 1597) of AML patients were primary refractory to HiDAC-based regimens at the MD Anderson Cancer Center between 1995 and 2009. AHSCT was the initial salvage in 28 cases. These patients were compared against 149 patients who received salvage chemotherapy, but never received AHSCT. Patients receiving salvage chemotherapy were older, had higher bone marrow blasts percentage, and higher incidence of unfavorable cytogenetics (P < 0.001). Median time from induction to AHSCT was 76 days. Objective response was achieved in 23 of 28 patients (82%) undergoing AHSCT. The incidence of grade III/IV acute and chronic graft versus-host-disease was 11% and 29%, respectively. Median follow up for living patients is 80 months. Median overall survival (OS) was 15.7 months and 2.9 months for AHSCT and chemotherapy, respectively (P < 0.001); the 3-year OS rates were 39% and 2%, respectively. ASHCT as initial salvage therapy was identified as an independent prognostic factor for survival in multivariate analysis (HR = 3.03; P < 0.001). Initial salvage therapy with AHSCT in patients with primary HiDAC refractory AML is feasible and may yield superior outcomes to salvage chemotherapy. PMID:24375514

    Cytomegalovirus (CMV) reactivates in >30% of CMV-seropositive patients after allogeneic hematopoietic cell transplantation (HCT). Previously, we reported an increase of natural killer (NK) cells expressing NKG2C, CD57, and inhibitory killer cell immunoglobulin-like receptors (KIRs) in response to CMV reactivation after HCT. These NK cells persist after the resolution of infection and display "adaptive" or memory properties. Despite these findings, the differential impact of persistent/inactive versus reactivated CMV on NK versus T cell maturation after HCT from different graft sources has not been defined. We compared the phenotype of NK and T cells from 292 recipients of allogeneic sibling (n = 118) or umbilical cord blood (UCB; n = 174) grafts based on recipient pretransplantation CMV serostatus and post-HCT CMV reactivation. This cohort was utilized to evaluate CMV-dependent increases in KIR-expressing NK cells exhibiting an adaptive phenotype (NKG2C(+)CD57(+)). Compared with CMV-seronegative recipients, those who reactivated CMV had the highest adaptive cell frequencies, whereas intermediate frequencies were observed in CMV-seropositive recipients harboring persistent/nonreplicating CMV. The same effect was observed in T cells and CD56(+) T cells. These adaptive lymphocyte subsets were increased in CMV-seropositive recipients of sibling but not UCB grafts and were correlated with lower rates of CMV reactivation (sibling 33% versus UCB 51%; P < .01). These data suggest that persistent/nonreplicating recipient CMV induces rapid production of adaptive NK and T cells from mature cells from sibling but not UCB grafts. These adaptive lymphocytes are associated with protection from CMV reactivation. PMID:26055301

    The prevalence of late effects following allogeneic hematopoietic cell transplantation (HCT), a curative treatment for pediatric leukemia, is high: 79% of HCT recipients experience chronic medical conditions. The few extant studies of cognitive late effects have focused on intelligence and are equivocal about HCT neurotoxicity. In an archival study of 30 children (mean transplant age = 6 years), we characterize neuropsychological predictors of academic outcomes. Mean intellectual and academic abilities were average, but evidenced extreme variability, particularly on measures of attention and memory: ∼25% of the sample exhibited borderline performance or lower. Medical predictors of outcome revealed paradoxically better memory associated with more severe acute graft-versus-host disease (GVHD) and associated with steroid treatment. Processing speed and memory accounted for 69% and 61% of variance in mathematics and reading outcomes, respectively. Thus, our findings revealed neurocognitive areas of vulnerability in processing speed and memory following HCT that contribute to subsequent academic difficulties. PMID:26319492

    Targeted busulfan/cyclophosphamide (TBU/CY) for allogeneic hematopoietic cell transplantation (HCT) carries a high risk of sinusoidal obstruction syndrome (SOS) in patients transplanted for myelofibrosis. We tested the hypothesis that reversing the sequence of administration (from TBU/CY to CY/TBU) will reduce SOS and day +100 non-relapse mortality (NRM). We enrolled 51 patients with myelofibrosis (n=20), acute myeloid leukemia (AML, n=20), or myelodysplastic syndrome (MDS, n=11) in a prospective trial of CY/TBU conditioning for HCT. Cyclophosphamide 60 mg/kg/day IV for two days was followed by daily IV BU for four days, targeted to a concentration at steady state (Css) of 800–900 ng/mL. CY/TBU-conditioned patients had higher exposure to CY (p<0.0001) and lower exposure to 4-hydroxyCY (p<0.0001) compared to TBU/CY-conditioned patients. Clinical outcomes were compared with controls (n=271) conditioned with TBU/CY for the same indications. In patients with myelofibrosis, CY/TBU conditioning was associated with a significantly reduced incidence of SOS (0% vs. 30% after TBU/CY, p=0.006), while SOS incidence was low in both cohorts with AML/MDS. Day +100 mortality was significantly lower in the CY/TBU cohort (2% vs. 13%, p=0.01). CY/TBU conditioning markedly impacted CY pharmacokinetics and was associated with significantly lower incidences of SOS and day +100 mortality, suggesting that CY/TBU is superior to TBU/CY as conditioning for patients with myelofibrosis.

    In experimental models, ex vivo induced T-cell rapamycin resistance occurred independent of T helper 1 (Th1)/T helper 2 (Th2) differentiation and yielded allogeneic CD4+ T cells of increased in vivo efficacy that facilitated engraftment and permitted graft-versus-tumor effects while minimizing graft-versus-host disease (GVHD). To translate these findings, we performed a phase 2 multicenter clinical trial of rapamycin-resistant donor CD4+ Th2/Th1 (T-Rapa) cells after allogeneic-matched sibling donor hematopoietic cell transplantation (HCT) for therapy of refractory hematologic malignancy. T-Rapa cell products, which expressed a balanced Th2/Th1 phenotype, were administered as a preemptive donor lymphocyte infusion at day 14 post-HCT. After T-Rapa cell infusion, mixed donor/host chimerism rapidly converted, and there was preferential immune reconstitution with donor CD4+ Th2 and Th1 cells relative to regulatory T cells and CD8+ T cells. The cumulative incidence probability of acute GVHD was 20% and 40% at days 100 and 180 post-HCT, respectively. There was no transplant-related mortality. Eighteen of 40 patients (45%) remain in sustained complete remission (range of follow-up: 42-84 months). These results demonstrate the safety of this low-intensity transplant approach and the feasibility of subsequent randomized studies to compare T-Rapa cell-based therapy with standard transplantation regimens. This trial was registered at www.cancer.gov/clinicaltrials as #NCT 00077480. PMID:23426943

    The mismatched minor histocompatibility antigens present on Y chromosome (H-Y) in male recipients receiving stem cells from female donors may contribute to graft-versus-leukemia effect (GVL) and results in reduce relapse rate especially in patients with high-risk disease. We retrospectively compared the outcomes of male AML patients who received an allogeneic hematopoietic stem cell transplant (HSCT) from female donors (F-M) (174 patients) versus other gender combinations (667 patients). Median age was 50 years (range 18–74 years). For the whole group, the one-year cumulative incidence of relapse was significantly lower in F-M group (34.1% versus 41.3%, p=0.044) while non-relapse mortality (NRM) was higher (23.2% versus 15.7%, p=0.004). For patients younger than 50 years beyond first complete remission, the F-M group was associated with lower relapse rate (42.5% versus 55.2%, p=0.045) whereas NRM was not significantly different (35.8% versus 25.5%, p=0.141). Although survival was not significantly improved, transplantation from a female donor for male recipient was associated with a lower relapse rate. When relapse is most common concern for treatment failure, especially for younger patients, a female donor for a male recipient might be beneficial to decrease relapse rate post-transplant. Future studies are needed to explore how H-Y mismatch may improve survival post-transplant. PMID:25540936

    The optimal conditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute leukemia remains undefined. We evaluated the outcomes in 30 patients with acute leukemia who underwent allo-HSCT from human leukocyte antigen-matched donors after conditioning with busulfan and fludarabine (BuFlu). The regimen comprised injection of busulfan 3.2 mg/kg daily on 4 consecutive days and fludarabine 30 mg/m2 daily for 4 doses. All 30 patients achieved hematopoiesis reconstitution with full donor chimerism confirmed by short tandem repeat DNA analysis. The most common regimen-related toxicity was mucositis (86.7%), followed by cytomegalovirus infection (80%). Serious regimen-related toxicities were rare. Acute graft vs. host disease (aGVHD) was detected in 46.7% of the patients; 33.4% had grade I–II aGVHD and 13.3% had grade III–IV aGVHD. Chronic GVHD (cGVHD) was noted in 20% of the patients. The overall survival and disease-free survival rates were 66.7 and 53%, respectively, with a median follow-up of 25 months for surviving patients. Therefore, BuFlu was an effective conditioning regimen with a low rate of transplant-related adverse effects and increased antileukemic effects in patients with acute leukemia undergoing allo-HSCT.

    Impaired cardiorespiratory fitness is associated with inferior survival in patients preparing to undergo hematopoietic cell transplantation (HCT). Exercise training based on short, higher intensity intervals has the potential to efficiently improve cardiorespiratory fitness. We studied home-based interval exercise training (IET) in 40 patients before autologous (N=20) or allogeneic (N=20) HCT. Each session consisted of five, 3 min intervals of walking, jogging or cycling at 65-95% maximal heart rate (MHR) with 3 min of low-intensity exercise (<65% MHR) between intervals. Participants were asked to perform sessions at least three times weekly. The duration of the intervention was at least 6 weeks, depending on each patient's scheduled transplantation date. Cardiorespiratory fitness was assessed from a peak oxygen consumption test (VO2peak) and a 6 min walk (6MWD) before and after the intervention period. For the autologous HCT cohort, improvements in VO2peak (P=0.12) and 6MWD (P=0.19) were not statistically significant. For the allogeneic cohort, the median VO2peak improvement was 3.7 ml/kg min (P=0.005) and the median 6MWD improvement was 34 m (P=0.006). Home-based IET can be performed before HCT and has the potential to improve cardiorespiratory fitness. PMID:26999467

    Previous studies have repeatedly reported that increasing age is a significant risk factor for worse outcomes after allogeneic hematopoietic stem cell transplantation (allo-HSCT) among patients with acute myeloid leukemia (AML). However, more recent studies reported conflicting results regarding the association between age and outcomes in elderly patients. Therefore, we conducted a large-scale, nationwide retrospective study to examine the impact of age on outcomes of allo-HSCT with reduced intensity conditioning (RIC) for AML patients who were older than 50 years. Of the 757 patients, 89 patients (11.8%) were 50-54, 249 patients (32.9%) were 55-59, 301 patients (39.8%) were 60-64 and 118 patients (15.6%) were ≥65 years old. The 3-year overall survival (OS) (47.8, 45.2, 37.9, and 36.6% for patients aged 50-54, 55-59, 60-64, and ≥65 years, respectively, P = 0.24) and nonrelapse mortality (NRM) (24.0, 22.8, 29.2, and 27.6% for patients aged 50-54, 55-59, 60-64, and ≥65 years, respectively, P = 0.49) were not significantly different among the four age groups. Multivariate analysis revealed that increased age had no significant effect on OS or NRM after adjusting for covariates. These results suggested that advanced patient age is not a contraindication for RIC allo-HSCT in elderly AML patients. PMID:26663096

    Invasive aspergillosis (IA) is a serious complication in patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT), particularly from donors other than HLA-identical sibling. All 306 patients who underwent alternative donor HSCT between 01 January 1999 and 31 December 2006 were studied. Late IA was defined as occurring >or=40 days after HSCT. The median follow-up was 284 days (range, 1-2709). Donors were matched unrelated (n=185), mismatched related (n=69), mismatched unrelated (n=35) and unrelated cord blood (n=17). According to European Organization for Research and Treatment of Cancer/Mycoses Study Group criteria, 2 patients already had IA at HSCT, 23 had early IA and 20 had late IA (IA incidence 15%). Eight patients had proven and 37 probable IA. Multivariate analyses showed that significant predictors of IA were delayed neutrophil engraftment, extensive chronic GVHD (cGVHD), secondary neutropenia and relapse after transplant. Early IA was associated with active malignancy at HSCT, CMV reactivation and delayed lymphocyte engraftment. Late IA was predicted by cGVHD, steroid therapy, secondary neutropenia and relapse after HSCT. IA-related mortality among IA patients was 67% and was influenced by use of anti-thymocyte globulin, steroids, higher levels of creatinine, and lower levels of IgA and platelets. The outcome of IA depends on the severity of immunodeficiency and the status of the underlying disease. PMID:19308042

    Purpose There is currently no standard chemotherapy regimen for patients with lymphoid malignancies being considered for reduced-intensity conditioning allogeneic hematopoietic stem-cell transplantation (RIC-alloHSCT). The ideal regimen would provide disease control and result in lymphocyte depletion to facilitate engraftment. To this end, we developed a novel regimen by adding fludarabine to dose-adjusted continuous-infusion etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin plus with or without rituximab (DA-EPOCH-F/R). Patients and Methods One hundred forty-seven patients with lymphoid malignancy (median age, 50 years) who had heavily pretreated (median prior regimens, three) and chemo-refractory (47%) disease were treated with DA-EPOCH-F/R before RIC-alloHSCT. Patients received one to three consecutive cycles until achieving lymphocyte depletion (CD4+ count < 200/μL) or progressive disease. Results Overall response rate was 41%; 39% of patients had stable disease. Toxicity included grade 4 neutropenia in 65% and thrombocytopenia in 25% of patients. DA-EPOCH-F/R resulted in lymphocyte depletion (P < .001), which was inversely associated with serum interleukin (IL) 7 and IL-15 levels. Of 147 patients, 143 patients proceeded to RIC-alloHSCT. Patients with lower CD3+ (P < .001), CD4+ (P < .001), and CD8+ (P < .001) T-cell counts after DA-EPOCH-F/R were more likely to achieve full donor lymphoid chimerism by day +14 after transplant. Relative to nonresponders to DA-EPOCH-F/R, patients with complete and partial response had increased event-free survival (77.4 v 4.8 months; P < .001) and overall survival (98.5 v 16.2 months; P < .001). Conclusion DA-EPOCH-F/R safely provides tumor cytoreduction and lymphocyte depletion, thereby offering a bridge to RIC-alloHSCT in patients with aggressive lymphoid malignancies. PMID:22312100

    Dental pulp calcification is a common finding associated with localized dental trauma, genetic disorders, and systemic inflammatory diseases. Chronic graft-versus-host disease (cGVHD) is a frequent complication after allogeneic hematopoietic cell transplantation (allo-HCT) characterized by immune-mediated injury to the skin, mouth, eyes, liver, and other tissues, resulting in significant disability and reduced quality of life. We report a patient with sclerodermatous cGVHD who presented with general pulp calcification in all teeth 5 years after allo-HCT. A review of full mouth dental radiographs obtained just before allo-HCT revealed normal-appearing pulp chambers. Based on prior reports of generalized pulp calcification associated with progressive systemic sclerosis, we hypothesized that the etiology was likely related to the presence of cGVHD with associated vascular and fibrotic tissue changes within the pulp vasculature. Clinicians should consider cGVHD in the differential diagnosis of generalized pulp calcification. PMID:26906241

    Purpose To determine the prognostic impact of persistent cytogenetic abnormalities at complete remission (CR) on relapse-free survival (RFS) and overall survival (OS) in patients with acute myeloid leukemia (AML) and to examine the potential role of allogeneic stem-cell transplantation (SCT) in this setting. Patients and Methods Data from 254 adult patients with AML (excluding acute promyelocytic leukemia) who achieved CR after induction chemotherapy on various first-line protocols were examined. Results Median follow-up for surviving patients was 43 months. Patients with cytogenetic abnormalities at CR (n = 71) had significantly shorter RFS (P = .001) and OS (P < .001) compared with patients with normal cytogenetics at CR (n = 183); 3-year RFS was 15% and 45%, and 3-year OS was 15% and 56%, respectively. Among the patients with persistent cytogenetic abnormalities at CR, those who underwent SCT in first CR (CR1; n = 15) had better RFS and OS compared to those without SCT (n = 56; P = .04 and .06, respectively). In multivariate analysis, persistent cytogenetic abnormalities at CR was an independent predictor for RFS (P < .001) and OS (P = .001), but among patients with persistent cytogenetic abnormalities at CR, no significant differences in OS (P = .25) was observed between those who did or did not receive SCT with a trend favoring SCT for RFS (P = .08). Conclusion Persistent cytogenetically abnormal cells at CR predict a significantly shorter RFS and OS. SCT in CR1 may improve the clinical outcome of patients lacking cytogenetic remission after induction although this depends on patient selection. PMID:21555694

    We investigated the efficacy of an antithymocyte globulin/cyclophosphamide preparative regimen prior to allogeneic stem cell transplantation from HLA-identical siblings in patients with severe aplastic anemia. Since 1990, 21 patients, 6 males and 15 females, with a median age of 25 years (range: 7-43) have been enrolled in the protocol consisting of 200 mg/kg cyclophosphamide and 90-120 mg/kg antithymocyte globulin (ATG, rabbit, Fresenius, Bad Homburg, Germany). For further graft-versus-host disease (GVHD) prophylaxis all patients received cyclosporin A and a short course of methotrexate (MTX). Only one patient had a primary graft failure (5%). All other patients engrafted with a leukocyte count >1.0 x 10(9)/l and a platelet count >20 x 10(9)/l after a median of 19 (range: 11-28) and 26 days (range: 13-67), respectively. No late graft failure or relapse was observed. Two patients experienced mild acute GVHD grade I (10%), and one patient developed grade II GVHD (5%). No severe grade III/IV GVHD was observed; 17% of the patients developed limited chronic GVHD. The treatment-related mortality was 14% and mainly due to fungal infection. After a median follow-up of 70 months (range: 2-139), the estimated overall and event-free survival at 10 years for all patients is 86% (95% confidence interval: 70-100%). We conclude that ATG plus cyclophosphamide is an effective conditioning regimen in patients with aplastic anemia undergoing stem cell transplantation with a low treatment-related mortality, resulting in an excellent outcome.

    We evaluated ABO associated outcomes in 1,737 patients who underwent allogeneic hematopoietic cell transplant (allo-HCT) at Stanford University between January 1986 and July 2011. Grafts were 61% ABO matched, 18% major mismatched (MM), 17% minor MM, and 4% bidirectional MM. Median follow-up was 6 years. In multivariate analysis, OS was inferior in minor MM HCT (median 2.1 vs 6.3 years; HR 1.56; 95%CI 1.19-2.05; p=0.001) in comparison with ABO matched grafts. ABO minor MM was associated with an increase in early NRM (18% vs 13%; HR 1.48, 95%CI 1.06-2.06; p=0.02). In an independent Center for International Blood and Marrow Transplant Research (CIBMTR) analysis of 435 lymphoma patients receiving mobilized peripheral blood grafts, impairment of OS (HR 1.55; 95%CI 1.07 – 2.25; p=0.021) and increased NRM (HR 1.72; 95%CI 1.11 – 2.68; p=0.03) was observed in recipients of ABO minor MM grafts. A second independent analysis of a CIBMTR dataset including 5,179 patients with AML and MDS identified a non-significant trend toward decreased OS in recipients of ABO minor MM grafts and also found ABO major MM to be significantly associated with decreased OS (HR 1.19, 95% CI 1.08 – 1.31, p<0.001) and increased NRM (HR 1.23, 95%CI 1.08 – 1.4, p=0.002). ABO minor and major MM are risk factors for worse transplant outcomes, although the associated hazards may not be uniform across different transplant populations. Further study is warranted to determine which patient populations are at greatest risk, and whether this risk can be modified by anti-B-cell therapy or other peri-transplant treatments.

    The impact of pre-transplant serum C-reactive protein (CRP) level on the outcome of reduced-intensity conditioning allogeneic hematopoietic stem cell transplantation (RIC allo-SCT) is unclear. This study retrospectively investigated 78 patients who underwent RIC allo-SCT between 2005 and 2013. The conditioning regimen consisted of fludarabine and melphalan with/without total body irradiation. The 3-year overall survival of high CRP (43.6 % of all patients) patients was significantly worse than that of normal CRP patients in whom CRP was ≤0.3 mg/dl (26.7 vs. 74.1 %, P < 0.001). Both the CRP level before transplantation and disease risk status were independent prognostic factors for overall survival by multivariate analysis. CRP was not a significant predictor of NRM by multivariate analysis (hazard ratio 3.2, 95 % confidence interval 0.8-13.1, P = 0.100). These results suggest that measuring the CRP level before transplantation can be useful to predicting the outcome of RIC allo-SCT. PMID:26791379

    The most frequent form of congenital dyserythropoiesis (CDA) is congenital dyserythropoietic anemia II (CDA II). CDA II is a rare genetic anemia in humans, inherited in an autosomally recessive mode, characterized by hepatosplenomegaly normocytic anemia and hemolytic jaundice. Patients are usually transfusion-independent except in severe type. We are here reporting a case of severe transfusion-dependent type II congenital dyserythropoietic anemia in a 5-year-old patient who has undergone allogeneic hematopoietic stem cell transplantation (HSCT) at our bone marrow transplantation centre. Patient has had up until now more than 14 mL/kg/month of packed cell volume (PCV), which he required every 15 to 20 days to maintain his hemoglobin of 10 gm/dL and hematocrit of 30%. His pre-HSCT serum ferritin was 1500 ng/mL and he was on iron chelating therapy. Donor was HLA identical sibling (younger brother). The preparative regimen used was busulfan, cyclophosphamide, and antithymocyte globulin (Thymoglobulin). Cyclosporine and short-term methotrexate were used for graft versus host disease (GVHD) prophylaxis. Engraftment of donor cells was quick and the posttransplant course was uneventful. The patient is presently alive and doing well and he has been transfusion-independent for the past 33 months after HSCT. PMID:25692053

    Autoimmune hemolytic anemia (AIHA) is a recognized complication of hematopoietic stem cell transplantation (HSCT); it is often refractory to treatment and carries a high mortality. To improve understanding of the incidence, risk factors, and clinical outcome of post-transplantation AIHA, we analyzed 533 patients who received allogeneic HSCT, and we identified 19 cases of AIHA after HSCT (overall incidence, 3.6%). The median time to onset, from HSCT to AIHA, was 202 days. AIHA was associated with HSCT from unrelated donors (hazard ratio [HR], 5.28; 95% confidence interval [CI], 1.22 to 22.9; P = .026). In the majority (14 of 19; 74%) of AIHA patients, multiple agents for treatment were required, with only 9 of 19 (47%) patients achieving complete resolution of AIHA. Patients with post-transplantation AIHA had a higher overall mortality (HR, 2.48; 95% CI, 1.33 to 4.63; P = .004), with 36% (4 of 11 cases) of deaths attributable to AIHA. PMID:25262883

    We report the clinical results of sustainedly integrating imatinib and interferon-α into maintenance therapy in the patients ineligible for allogeneic hematopoietic stem cell transplantation (allo-HSCT). Maintenance therapy lasted for 5 years with imatinib 400 mg daily, interferon-α 3 million units, 2∼3 doses per week, and chemotherapy including vindesine and dexamethasone scheduled monthly in first year, once every 2 months in second year, and once every 3 months in third year. The chemotherapy was discontinued after 3 years and the imatinib and interferon-α continued for another 2 years. For 41 patients without allo-HSCT with a median follow-up of 32 months, the 3-year DFS and OS were 42.7  ± 8.6% and 57.9  ± 8.4%, respectively. Our study suggests that sustaining maintenance with low-dose chemotherapy, imatinib and interferon-α improved survival of adult Philadelphia-positive acute lymphoblastic leukemia (Ph + ALL) patients ineligible for allo-HSCT, and even provided an opportunity for cure. BCR/ABL persistent negativity at 6 and 9 months may have benefit to choose suitable patients for the imatinib/interferon-α maintenance strategy. PMID:26879808

    Despite survival improvement with novel agents and use of autologous hematopoietic stem cell transplantation (HSCT), cure of patients with multiple myeloma (MM) remains anecdotal. Initial observations suggested that chronic GvHD was accompanied by an anti-myeloma effect after myeloablative HSCT, but unfortunately this procedure was hampered by high non-relapse mortality (NRM). To maximize the anti-myeloma effect and minimize NRM, we developed a non-myeloablative (NMA) regimen associated with a high incidence of chronic GvHD and tested its efficacy on patient survival and disease eradication. From 2001 to 2010, 92 patients aged⩽65 years with a compatible sibling donor received autologous HSCT followed by an outpatient NMA allogeneic HSCT using a conditioning of fludarabine and cyclophosphamide. Patient median age was 52 years and 97% presented Durie-Salmon stages II-III disease. After a median follow-up of 8.8 years, probability of 10-year progression free and overall survival were 41% and 62%, respectively. Although the cumulative incidence of extensive chronic GvHD was high (at 79%), the majority of long-term survivors were off immunosuppressive drugs by year 5 and NRM was low (at 10%). Together, our results suggest that potential MM cure can be achieved with NMA transplantation regimens that maximize graft-versus-myeloma effect and minimize NRM. PMID:26691426

    Plasmacytoid dendritic cells (pDCs) bridge innate and adaptive immune responses and have important roles in hematopoietic engraftment, GvHD and graft-versus-leukemia responses following allogeneic hematopoietic cell transplantation (HCT). In addition, pDCs mediate antiviral immunity, particularly as they are the body’s primary cellular source of type I interferon. Given their pleiotropic roles, pDCs have emerged as cells that critically impact transplant outcomes, including overall survival. In this article, we will review the pre-clinical and clinical literature, supporting the crucial roles that pDCs assume as key immune effector cells during HCT. PMID:26642333

    Poor graft function (PGF) is a severe complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The question of whether the bone marrow (BM) immune microenvironment is involved in the pathogenesis of PGF remains unresolved. In total, 10 patients with PGF, 30 matched patients with good graft function after allo-HSCT, and 15 healthy donors were enrolled in this nested case-control study. The Th1, Th2, Tc1, Tc2, and active phenotypes were analyzed by flow cytometry. IFN-γ and IL-4 levels in BM plasma were evaluated using cytometric beads assay. Relative to other subjects, patients with PGF had significantly higher proportions of stimulated CD4(+) and CD8(+) T cells that produced IFN-γ (Th1 and Tc1 cells) but notably decreased proportions of IL-4-producing T cells (Th2 and Tc2 cells), resulting in a shift of the IFN-γ/IL-4 ratio towards a type 1 response and an elevated percentage of activated CD8(+) T cells. Changes in IFN-γ and IL-4 levels in BM plasma were consistent with the cellular results. Our results suggest that dysregulated T cell responses may contribute to the occurrence of PGF after HSCT.

    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.

    Reduced intensity conditioning/non-myeloablative conditioning regimens are increasingly used in allogeneic hematopoietic cell transplantation (HCT). Reports have shown CD34+ dose to be important for transplant-outcome using myeloablative conditioning. The role of CD34+ dose of peripheral blood progenitor cells (PBPC) has not been previously analyzed in a large population undergoing reduced intensity conditioning/non-myeloablative HCT. We studied 1,054 patients aged 45–75 years, with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) transplanted between 2002 and 2011. Results of multivariate analysis showed that PBPC from HLA-matched siblings containing <4 × 106 CD34+/kg were associated with higher non-relapse mortality (HR 2.03, p=0.001), overall mortality (HR 1.48, p=0.008), and lower neutrophil (OR 0.76, p=0.03) and platelet (OR 0.76, p=0.03) recovery. PBPC from unrelated donors with CD34+ dose <6 × 106 CD34+/kg were also associated with higher non-relapse (HR 1.38, p=0.02) and overall mortality (HR 1.20, p=0.05). In contrast to reports after myeloablative HCT, CD34+ dose did not affect relapse or graft-versus-host disease with either donor type. An upper cell dose limit was not associated with adverse outcomes. These data suggest that PBPC CD34+ dose >4 × 106 CD34+/kg and >6 × 106 CD34+/kg are optimal for HLA-matched sibling and unrelated donor HCT, respectively. PMID:24892261

    Next-generation sequencing of the hypervariable V3 region of the 16s rRNA gene isolated from serial stool specimens collected from 31 patients receiving allogeneic stem cell transplantation (SCT) was performed to elucidate variations in the composition of the intestinal microbiome in the course of allogeneic SCT. Metagenomic analysis was complemented by strain-specific enterococcal PCR and indirect assessment of bacterial load by liquid chromatography-tandem mass spectrometry of urinary indoxyl sulfate. At the time of admission, patients showed a predominance of commensal bacteria. After transplantation, a relative shift toward enterococci was observed, which was more pronounced under antibiotic prophylaxis and treatment of neutropenic infections. The shift was particularly prominent in patients that developed subsequently or suffered from active gastrointestinal (GI) graft-versus-host disease (GVHD). The mean proportion of enterococci in post-transplant stool specimens was 21% in patients who did not develop GI GVHD as compared with 46% in those that subsequently developed GI GVHD and 74% at the time of active GVHD. Enterococcal PCR confirmed predominance of Enterococcus faecium or both E. faecium and Enterococcus faecalis in these specimens. As a consequence of the loss of bacterial diversity, mean urinary indoxyl sulfate levels dropped from 42.5 ± 11 µmol/L to 11.8 ± 2.8 µmol/L in all post-transplant samples and to 3.5 ± 3 µmol/L in samples from patients with active GVHD. Our study reveals major microbiome shifts in the course of allogeneic SCT that occur in the period of antibiotic treatment but are more prominent in association with GI GVHD. Our data indicate early microbiome shifts and a loss of diversity of the intestinal microbiome that may affect intestinal inflammation in the setting of allogeneic SCT. PMID:24492144

    Severe oral mucositis is a major cause of morbidity following allogeneic hematopoietic stem cell transplantation (AHSCT). Cryotherapy, that is, the application of ice chips on the mucosa of the oral cavity during the administration of antineoplastic agents, may reduce the incidence and severity of chemotherapy-related oral mucositis. In this multicenter randomized study, we addressed whether cryotherapy during MTX administration is effective in the prevention of severe oral mucositis in patients undergoing myeloablative AHSCT. One hundred and thirty patients undergoing myeloablative AHSCT and MTX-containing GVHD prophylaxis were enrolled and randomized to receive or not receive cryotherapy during MTX administration. The incidence of severe (grade 3-4) oral mucositis, the primary end point of the study, was comparable in patients receiving or not cryotherapy. Moreover, no difference was observed in the incidence of oral mucositis grade 2-4 and the duration of oral mucositis grade 3-4 or 2-4, or in the kinetics of mucositis over time. In univariate and multivariate analysis, severe oral mucositis correlated with TBI in the conditioning regimen and lack of folinic acid rescue following MTX administration. Thus, cryotherapy during MTX administration does not reduce severe oral mucositis in patients undergoing myeloablative allogeneic HSCT. Future studies will assess cryotherapy before allogeneic HSCT.

    Posaconazole oral suspension (PCZ-susp) can display a variable degree of inter and intra-individual absorption. However, there is no agreement on the need of plasma-posaconazole-concentration (PPC) monitoring as a routine practice in patients receiving PCZ-susp. In this prospective, multicenter study we evaluated the variability of PPCs in hematologic patients receiving PCZ-susp prophylaxis with the aim to define conditions at different risk of subtherapeutic PPCs. Overall, 103 acute leukemia (AL) patients submitted to intensive chemotherapy (115 courses) and 46 allogeneic stem cell transplant (allo-SCT) recipients (47 courses) receiving PCZ-susp prophylaxis were considered. The adequacy of PPC pattern after the steady state (≥day 7 of treatment) in courses with two or more PPC measurements was defined as follows: inadequate pattern: PPC < 0.5 mcg/ml at least once; borderline pattern: PPC always ≥0.5mcg/ml but < 0.7 mcg/ml at least once; adequate pattern: PPC always ≥0.7 mcg/ml. The PPC pattern was evaluable in 83 and 37 AL and allo-SCT patients, respectively. It was adequate, borderline and inadequate in 63.9%, 14.5%, and 21.7% of courses, respectively, in AL, and in 62.2%, 10.8%, and 27.0% of courses, respectively, in allo-SCT. In both groups, an inadequate PPC pattern was associated with the development of diarrhea. In absence of diarrhea, the probability of an inadequate PPC pattern was 11.9% in AL and 17.2% in allo-SCT patients. PCZ-susp might be used without stringent need of PPC monitoring in patients without diarrhea. PMID:26868905

    In allogeneic hematopoietic stem-cell transplantation (HSCT) recipients, outcome of human cytomegalovirus (HCMV) infection results from balance between viral load/replication and pathogen-specific T-cell response. Using a cut-off of 30,000 HCMV DNA copies/ml blood for pre-emptive therapy and cut-offs of 1 and 3 virus-specific CD4+ and CD8+ T cells/µl blood for T-cell protection, we conducted in 131 young patients a prospective 3-year study aimed at verifying whether achievement of such immunological cut-offs protects from HCMV disease. In the first three months after transplantation, 55/89 (62%) HCMV-seropositive patients had infection and 36/55 (65%) were treated pre-emptively, whereas only 7/42 (17%) HCMV-seronegative patients developed infection and 3/7 (43%) were treated. After 12 months, 76 HCMV-seropositive and 9 HCMV-seronegative patients (cumulative incidence: 90% and 21%, respectively) displayed protective HCMV-specific immunity. Eighty of these 85 (95%) patients showed spontaneous control of HCMV infection without additional treatment. Five patients after reaching protective T-cell levels needed pre-emptive therapy, because they developed graft-versus-host disease (GvHD). HSCT recipients reconstituting protective levels of HCMV-specific T-cells in the absence of GvHD are no longer at risk for HCMV disease, at least within 3 years after transplantation. The decision to treat HCMV infection in young HSCT recipients may be taken by combining virological and immunological findings. PMID:22848556

    As the number of young long-term survivors of hematopoietic stem cell transplantation (HSCT) for acute leukemia continues to increase, post-transplant infertility is becoming a significant concern. HSCT, particularly with cyclophosphamide and total body irradiation conditioning, is known to cause secondary premature ovarian failure, resulting in infertility. To preserve post-transplant fertility, several methods have been proposed, including in vitro fertilization (IVF) with embryo cryopreservation. Due to the aggressiveness of acute leukemia, however, patients have little chance to undergo egg harvesting and IVF before they must begin receiving chemotherapy. To the best of our knowledge, there have been no detailed reports of successful pregnancy after HSCT using IVF with embryo cryopreservation and transfer in a patient with acute myeloid leukemia. Here, we report the case of a 42-year-old woman with acute myeloid leukemia who became pregnant 2 years and 2 months after allogeneic bone marrow transplantation via IVF-embryo transfer with an egg collected after induction therapy and delivered a full-term healthy infant.

    Positron emission tomography (PET) integrated with computed tomography (PET/CT) has been reported to be useful for screening myelomatous lesions at diagnosis in patients with multiple myeloma (MM) and for monitoring response to autologous stem cell transplantation (auto-SCT). The aim of the study was to evaluate the prognostic significance of PET/CT in MM patients who received allogeneic stem cell transplantation (allo-SCT). Patients who underwent upfront auto-SCT followed by allo-SCT, either as consolidation or salvage treatment, were studied with PET/CT before and/or within 6 months after allo-SCT. The number, the maximum standard uptake value (SUV), and the location (medullary or extramedullary) of focal lesions (FLs) were recorded and investigated as predictors of progression-free survival (PFS) and overall survival (OS) by univariate and multivariate analyses. Fifty-four patients had a PET/CT scan before allo-SCT. Of these, 22 patients (41%) had a negative PET/CT scan, 11 patients (20%) showed 1 to 3 FLs, and 21 patients (39%) had either a diffuse bone marrow involvement or more than 3 FLs. SUV was >4.2 in 21 patients (39%) and extramedullary disease (EMD) was present in 6 patients (11%). Multivariate analysis of prognostic factors before allo-SCT showed that persistence of EMD at transplantation was an independent predictor of poor PFS, whereas OS was negatively influenced by unrelated donor and SUV > 4.2. Fifty-nine patients had a PET/CT scan within 6 months after allo-SCT. Multivariate analysis of post-treatment variables showed that persistence of EMD and failure to obtain complete response or very good partial response after allo-SCT were strongly associated with shorter PFS and OS. Of the 46 patients with evaluable PET/CT scans both before and 6 months after allo-SCT, the 23 patients who maintained or reached a PET complete remission showed a significantly prolonged PFS and OS compared with the 23 patients with persistence of any PET positivity (2-year

    Tyrosine kinase inhibitors (TKIs) and reduced intensity conditioning (RIC)/nonmyeloablative (NMA) conditioning hematopoietic cell transplants (HCTs) have changed the therapeutic strategy for chronic myelogenous leukemia (CML) patients. We analyzed post-HCT outcomes of 306 CML patients reported to the Center for International Blood and Marrow Transplant Research aged 40 years and older undergoing RIC/NMA HCT from 2001 to 2007: 117 (38%) aged 40 to 49 years, 119 (39%) 50 to 59 years, and 70 (23%) 60 years or older. The majority (74%) had treatment with imatinib before HCT. At HCT, most patients aged 40 to 49 years were in chronic phase (CP) 1 (74%), compared with 31% aged 60 years or older. Siblings were donors for 56% aged 40 to 49 years; older cohorts had more unrelated donors. The majority received peripheral blood grafts and RIC across all age groups. 3 year overall survival (54%, 52%, and 41%), day + 100 grade II-IV acute GVHD (26%, 32%, and 32%), chronic GVHD (58%, 51%, and 43%), and 1-year treatment-related mortality (18%, 20%, and 13%) were similar across ages. The 3-year relapse incidence (36%, 43%, and 66%) and disease-free survival (35%, 32%, and 16%) were inferior in the oldest cohort. Importantly, for CP1 patients, relapse and disease-free survival were similar across age cohorts. Allogeneic RIC HCT for older patients with CML can control relapse with acceptable toxicity and survival in TKI-exposed CML, especially if still in CP1. PMID:22408257

    We describe the clinical course of a patient who experienced refractory pure red cell aplasia (PRCA) after undergoing HLA-matched allogeneic peripheral blood stem cell transplantation (allo-PBSCT) for refractory anemia with an excess of blasts in transformation that had evolved from Kostmann syndrome. The treatment for patients with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) developing from Kostmann syndrome has not been standardized. We treated this patient with allo-PBSCT using a regimen combining high-dose cytosine arabinoside with granulocyte colony-stimulating factor, in addition to total body irradiation and cyclophosphamide without preceding intensive chemotherapy. The donor was ABO incompatible. Myeloid and platelet recoveries were achieved rapidly. Erythroid engraftment was not evident, however, and the patient was given a diagnosis of PRCA. Regimen-related toxicity and graft-versus-host disease (GVHD) were limited. The PRCA did not respond to various therapies, including the discontinuation of immunosuppressants for the induction of chronic GVHD, human recombinant erythropoietin, immunosuppressive treatment with steroids, cyclosporin A, and human anti-CD20 antibody (rituximab). The patient received transfusions 48 times until the resolution of his anemia by donor leukocyte infusion (DLI) at 25 months after PBSCT. He is now clinically well (performance status, 100%) with normal blood cell counts at 5 years after SCT. An in vitro study demonstrated that serum from the recipient blocked the differentiation of erythroid cells in the bone marrow. The results indicate that the conditioning regimen we describe seems safe and effective for those who have MDS/AML and that DLI might be a valuable approach for refractory PRCA after ABO-incompatible SCT.

    Allogeneic hematopoietic stem cell transplantation (HSCT) has become an established treatment modality for various hematological diseases. However, in allogeneic HSCT, patients often suffer from severe gastrointestinal complications caused by the conditioning regimen and acute/chronic graft-versus-host disease, which requires support by multidisciplinary nutritional support teams (NST). In addition, pretransplantation nutritional status can affect the clinical outcome after allogeneic HSCT. Therefore, it is important to refer the patient to a NST when becoming aware of nutritional problems before allogeneic HSCT. It is also important to follow nutritional status over the long term, as patients often suffer from various nutritional problems, such as malnutrition and metabolic syndrome, even late after allogeneic HSCT. In summary, NST can contribute to the improvement of nutritional status and possibly prognosis at every stage before and after allogeneic HSCT. Here, we aim to give a comprehensive overview of current understanding about nutritional support in allogeneic HSCT and try to provoke a constructive discussion to stimulate further investigation.

    DNMT3A mutations are frequent in cytogenetically normal acute myeloid leukemia (cn-AML) patients and associated with poor survival. The role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in DNMT3A(mut) cn-AML patients remains unclear. In this study, we retrospectively analyzed the prognostic impact of DNMT3A mutations and explored the role of allo-HSCT in 308 cn-AML patients who received consolidation of intensive chemotherapy or allo-HSCT in our center from March 2005 to May 2014. In the whole cohort, 63 patients (20.5%) were identified with DNMT3A exon 23 mutations and R882H was the most frequent variant. DNMT3A(mut) patients had shorter overall survival (3-year OS: 31.9% vs. 52.0%, P = 0.009) and disease-free survival (3-year DFS: 21.8% vs. 40.1%, P = 0.004) compared with DNMT3A(wt) patients. Based on FLT3/NPM1/CEBPA mutations, 308 cn-AML patients were divided into favorable/intermediate group (n = 262) and unfavorable group (n = 46). There were no significant differences in 3-year OS and 3-year DFS between DNMT3A(mut) and DNMT3A(wt) patients in both favorable/intermediate and unfavorable groups. Additionally, in multivariate analysis, DNMT3A mutation remained an independent adverse prognostic factor for the survival. In the DNMT3A(mut) cohort, 23 complete remission (CR) patients received allo-HSCT consolidation and 32 CR patients received chemotherapy consolidation, dramatic differences were observed in 3-year OS (51.7% vs. 28.9%, P = 0.048) and 3-year DFS (41.6% vs. 14.9%, P = 0.024) between allo-HSCT group and chemotherapy group. Collectively, DNMT3A mutation is a poor prognostic factor for cn-AML patients and allo-HSCT could improve survival of cn-AML patients with DNMT3A mutations. PMID:26223865

    Background Acute myeloid leukemia (AML) patients with mixed lineage leukemia (MLL) gene rearrangements always had a very poor prognosis. In this study, we report the incidence of MLL rearrangements in AML patients using gene analysis, as well as the clinical significance and prognostic features of these rearrangements. Material/Methods This retrospective study took place from April 2008 to November 2011 in the People’s Liberation Army General Hospital. A total 433 AML patients were screened by multiple nested reverse transcription polymerase chain reaction (RT-PCR) to determine the incidence of the 11 MLL gene rearrangements. There were 68 cases of MLL gene rearrangements, for a positive rate of 15.7%. A total of 24 patients underwent allogeneic hematopoietic stem cell transplantation (Allo-HSCT), and 34 patients received at least 4 cycles of chemotherapy. Ten patients were lost to follow-up. Results The median follow-up was 29 months. The complete remission (CR) rate was 85.4%. The overall survival (OS) was 57.4±5.9 months for the Allo-HSCT group and 21.0±2.1 months for the chemotherapy group. The Allo-HSCT group had superior survival compared with the chemotherapy group (5-year OS: 59±17% vs. 13±8%, P<0.01; 5-year disease-free survival [DFS]: 65±10% vs. 40±16%, P>0.05). Multivariate analysis showed that transplantation, platelets >50×109/L at onset, and CR are associated with a better OS in MLL rearranged AML patients. Patients with thrombocytopenia and extramedullary involvement were prone to relapse. Conclusions Our results suggest that Allo-HSCT is superior to chemotherapy alone for treating MLL rearranged AML patients. Patients treated with Allo-HSCT have a better prognosis and a longer survival. CR is an independent prognostic factor for OS, and extramedullary involvement is an independent prognostic factor for DFS. MLL rearranged AML patients with thrombocytopenia at onset <50×109 had very bad OS and DFS. PMID:27373985

    In the tyrosine kinase inhibitor (TKI) era, imatinib is the first-line therapy for patients with chronic myeloid leukemia (CML) in chronic or accelerated phase. Although second-generation TKIs (TKI2), including dasatinib and nilotinib, are appropriate treatment regimens for patients with disease that progressed to accelerated phase following imatinib therapy, allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only curative therapy. This study retrospectively analyzed the efficacy of TKI2 and HSCT for treatment of CML in accelerated phase. Ninety-three patients with CML registered in the Chinese CML alliance database from February 2001 to February 2014 were enrolled and divided into the TKI2 (n = 33) and allo-HSCT (n = 60) groups. In the TKI2 group, 26 and 7 patients received nilotinib and dasatinib, respectively, as initial TKI2 and 11 patients transferred to the alternative TKI2 after failure to one TKI2. In the allo-HSCT group, 22 (36.7%), 35 (58.3%), and 3 (10%) patients underwent allo-HSCT from an HLA-matched sibling donor, HLA mismatched/haploidentical donor, and unrelated donor, respectively. All patients in the HSCT group were engrafted. Overall, 69.7%, 48.5%, and 45.5% of patients presented hematological, cytogenetic, and major molecular responses, respectively, to at least one of TKI2. All 60 patients (100%) achieved CHR and cytogenetic response in the HSCT group. Patients in the TKI2 group exhibited lower 5-year overall survival rate (42.9% vs. 86.4%, P = 0.002), 5-year event-free survival rate (14.3% vs. 76.1%, P < 0.001), and 5-year progression-free survival (28.6% vs. 78.1%, P < 0.001) than those in the allo-HSCT group. Multivariate analysis showed that male sex and TKI2 therapy were predictors of poor overall survival, whereas hemoglobin < 100 g/L and TKI2 therapy were predictors of poor event-free survival and progression-free survival. These results indicated that allo-HSCT may be superior to nilotinib and dasatinib for adult

    After allogeneic hematopoietic stem cell transplantation (allo-HSCT), intestinal bacteria modulate risks of infection and graft-versus-host disease (GVHD). Neutropenic fever is common and treated with a choice of clinically equivalent antibiotics that target obligately anaerobic bacteria (anaerobes) to varying degrees. We retrospectively examined 857 allo-HSCT recipients and found that treatment of neutropenic fever with imipenem-cilastatin and piperacillin-tazobactam was associated with increased GVHD-related mortality at 5 years (21.5% in imipenem-cilastatin-treated patients vs. 13.1% in untreated patients, p=0.025, and 19.8% in piperacillin-tazobactam-treated patients vs. 11.9% in untreated patients, p=0.007). However, two other antibiotics also used to treat neutropenic fever, aztreonam and cefepime, were not associated with GVHD-related mortality (p=0.78 and p=0.98, respectively). Analysis of stool microbiota composition showed that piperacillin-tazobactam administration was associated with increased compositional perturbation. Studies in mouse models demonstrated similar effects of these antibiotics, as well as aggravated GVHD mortality with imipenem-cilastatin or piperacillin-tazobactm compared to aztreonam (p<0.01 and p<0.05, respectively). We found pathological evidence for increased GVHD in the colon of imipenem-cilastatin-treated mice (p<0.05), but no differences in short-chain fatty acid concentrations or regulatory T cells numbers. Notably, imipenem-cilastatin treatment of mice with GVHD led to loss of the protective lining of mucus in the colon (p<0.01) and intestinal barrier function was compromised (p<0.05). Sequencing of mouse stool specimens showed expansion of Akkermansia muciniphila (p<0.001), a commensal bacterium with mucus-degrading capabilities, raising the possibility that mucus degradation can contribute to murine GVHD. We demonstrate an underappreciated risk for antibiotics with activity against anaerobes to exacerbate colonic GVHD after

    Prognosis of leukemia relapse post allogeneic stem cell transplantation (alloSCT) is poor and effective new treatments are urgently needed. T cells are pivotal in eradicating leukemia through a graft versus leukemia (GVL) effect and leukemia relapse is considered a failure of GVL. T-cell exhaustion is a state of T-cell dysfunction mediated by inhibitory molecules including programmed cell death protein 1 (PD-1) and T-cell immunoglobulin domain and mucin domain 3 (TIM-3). To evaluate whether T-cell exhaustion and inhibitory pathways are involved in leukemia relapse post alloSCT, we performed phenotypic and functional studies on T cells from peripheral blood of acute myeloid leukemia patients receiving alloSCT. Here we report that PD-1hiTIM-3+ cells are strongly associated with leukemia relapse post transplantation. Consistent with exhaustion, PD-1hiTIM-3+ T cells are functionally deficient manifested by reduced production of interleukin 2 (IL-2), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ). In addition, these cells demonstrate a phenotype consistent with exhausted antigen-experienced T cells by losing TN and TEMRA subsets. Importantly, increase of PD-1hiTIM-3+ cells occurs before clinical diagnosis of leukemia relapse, suggesting their predictive value. Results of our study provide an early diagnostic approach and a therapeutic target for leukemia relapse post transplantation. PMID:26230954

    We report a case of a 40-year-old female who developed progressive multifocal leukoencephalopathy (PML), which is associated with JC virus reactivation, after allogeneic hematopoietic cell transplantation. As she had been suffering from graft-versus-host disease and lung damage after pneumocystis pneumonia, the administration of calcineurin inhibitor and steroid could not be discontinued. However, she showed a favorable improvement in clinical symptoms and imaging findings after treatment with the anti-malarial drug, mefloquine and a serotonin receptor blocker, mirtazapine. Continuation of the treatment for eight months finally led to the clearance of the JC virus from her cerebrospinal fluid. She currently shows no neurological disturbance and has resumed her daily activities. PML due to the severe immunosuppressive condition has been reported as a fatal complication after allo-SCT. Our case suggests that combination treatment with mefloquine and mirtazapine may be of great value for the treatment for PML patients in the post allo-SCT setting, although it is difficult to say whether the combination treatment alone led to improvement. Further clinical study is needed to clarify the efficacy of these drugs for the treatment of PML. PMID:24264833

    Although reduced intensity (RIC) and nonmyeloablative (NMA) conditioning regimens have been used for over a decade, their relative efficacy versus myeloablative (MA) approaches to allogeneic hematopoietic cell transplantation (HCT) in patients with acute myelogenous leukemia (AML) and myelodysplasia (MDS) is unknown. We compared disease status, donor, graft and recipient characteristics with outcomes of 3731 MA with 1448 RIC/NMA procedures performed at 217 centers between 1997 and 2004. Five year univariate probabilities and multivariate relative risk (RR) outcomes of relapse, transplant related mortality (TRM), disease free survival (DFS) and overall survival (OS) are reported. Adjusted OS at 5 years was 34%, 33%, and 26% for MA, RIC and NMA transplants, respectively. NMA conditioning resulted in inferior DFS and OS but there was no difference in DFS and OS between RIC and MA regimens. Late TRM negates early decreases in toxicity with RIC and NMA regimens. Our data suggest higher regimen intensity may contribute to optimal survival in patients with AML/MDS, suggesting roles for both regimen intensity and graft vs. leukemia in these diseases. Prospective studies comparing regimens are needed to confirm this finding and determine the optimal approach to patients who are eligible for either MA or RIC/NMA conditioning. PMID:21441963

    Current results show that 50% of young patients with ANLL who undergo allogeneic BMT experience prolonged DFS and may be cured. Encouraging results with high-dose chemo/radiotherapy and autologous BMT are likewise being reported. In addition, some studies using intensive postremission treatment without BMT have shown results comparable to many transplant series. As better ways of preventing GVHD are found, the morbidity and mortality of allogeneic BMT should be reduced and the benefits of transplantation for curing patients with ANLL should be increased. However, the applicability of allogeneic BMT will remain limited due to the availability of compatible donors whether related or unrelated. Further studies are needed in the use of postremission intensive therapy with and without autologous bone marrow support. However, results to date should engender the same degree of enthusiastic optimism that followed the early reports of improved outcome with allogeneic BMT when applied to first remission patients.

    Reduced intensity allogeneic stem cell transplantation (RI alloSCT) is a potentially curative treatment approach for patients with myelodysplastic syndrome (MDS). It is currently unclear if older related donors are better than younger unrelated donors for patients with MDS undergoing RI alloSCT. We retrospectively studied 53 consecutive MDS patients who underwent RI alloSCT between April 2007 and June 2014 and evaluated associations between donor type and outcomes with adjustment for significant covariates. 34 patients (median age: 64 years) and 19 patients (median age: 60 years) received allografts from unrelated and related donors, respectively. Unrelated donors were younger than related donors (median age: 32 vs. 60 years, P < 0.0001). There were no significant differences in baseline disease characteristics of patients receiving allografts from related or unrelated donors. Patients who received allografts from unrelated donors had a lower relapse risk (adjusted hazard ratio [aHR] = 0.35, P = 0.012) and improved relapse-free survival (aHR = 0.47, P = 0.018). HLA mismatched unrelated donors were associated with a higher risk of grade 2-4 acute graft versus host disease (GVHD) (HR = 4.64, P = 0.002) without an accompanying increase in the risk of non-relapse mortality (P = 0.56). Unrelated donors provided a higher mean CD8 cell dose (P = 0.014) and were associated with higher median donor T cell chimerism at day 60 (P = 0.003) and day 100 (P = 0.03). In conclusion, patients with MDS who received allografts from unrelated donors had a lower risk of relapse and improved relapse-free survival when compared to patients who received allografts from related donors. These findings should be confirmed in a prospective study. Am. J. Hematol. 91:883-887, 2016. © 2016 Wiley Periodicals, Inc. PMID:27197602

    Cytomegalovirus (CMV)-reactivation is associated with graft-vs-leukemia (GVL) effect by stimulating natural-killer or T-cells, which showed leukemia relapse prevention after hematopoietic stem cell transplantation (HSCT). We enrolled patients with acute myeloid leukemia (n = 197) and acute lymphoid leukemia (n = 192) who underwent allogeneic-HSCT in first remission. We measured RQ-PCR weekly to detect CMV-reactivation and preemptively used ganciclovir (GCV) when the titer increased twice consecutively, but GCV was sometimes delayed in patients without significant graft-vs-host disease (GVHD) by reducing immunosuppressive agents. In the entire group, CMV-reactivation showed poor overall survival (OS). To evaluate subsequent effects of CMV-reactivation, we excluded early relapse and deaths within 100 days, during which most of the CMV-reactivation occurred. Untreated CMV-reactivated group (n = 173) showed superior OS (83.8% vs. 61.7% vs. 74.0%, p < 0.001) with lower relapse rate (10.1% vs 22.1% vs. 25.5%, p = 0.004) compared to GCV-treated CMV-reactivated group (n = 122) and CMV-undetected group (n = 42). After excluding chronic GVHD, untreated CMV-reactivated group still showed lower relapse rate (9.4% vs. 24.1% vs. 30.2%, p = 0.006). Multivariate analysis showed adverse-risk karyotype and patients in other than untreated CMV-reactivated group were independent factors for relapse prediction. Our data showed possible GVL effect of CMV-reactivation and minimizing antiviral therapy may benefit for relapse prevention in acute leukemia. PMID:26883100

    The present study investigated the ability of supernatants collected from cultures of healthy donor-derived peripheral blood mononuclear cells (HD-PBMCs) stimulated with anti-CD3 monoclonal antibody (MAb) (allogeneic CD3 supernatants; ACD3S) to induce, upon brief exposure, tumour-reactive cytotoxic lymphocytes in cancer patients' PBMCs. ACD3S enhanced natural killer (NK) and lymphokine-activated killer (LAK) cell-mediated cytotoxicity. ACD3S contained increased levels of interleukins (IL) 1, 2, 6, 7 and 12, as well as of granulocyte-macrophage colony-stimulating factor (GM-CSF), gamma-interferon (IFN-gamma) and tumour necrosis factor-alpha (TNF-alpha). MAbs against these cytokines significantly reduced the ACD3S-induced cytotoxicity. ACD3S-induced cytotoxicity was not inhibited by anti-CD4, CD8 and MHC class I MAbs, but was markedly reduced in the presence of MAb against CD18. In contrast to HD-PBMC, ACD3S derived from cancer patients' lymphocytes exhibited lower levels of the above-mentioned cytokines and exerted reduced biological activity. In conclusion, ACD3S are able to activate, upon short-term incubation, tumour-reactive lymphocytes from cancer patients' PBMCs that lyse a variety of tumour targets, including autologous tumours. ACD3S contain high levels of certain cytokines that positively influence the induction of autologous tumour-reactive lymphocytes. Such supernatants can be collected easily from healthy donors and stored until use in clinical trials for adoptive cellular therapy of cancer. They may also be indicated in the construction of cytokine cocktails that have the ability to induce anti-tumour cytotoxicity. PMID:9376269

    With increased survival after pediatric allogeneic hematopoietic SCT health-related quality of life (HRQL) has emerged as an essential health outcome. The impact of transplant and chronic GVHD (cGVHD)-associated morbidity remains a major obstacle. In 2005, the National Institutes of Health (NIH) Consensus Conference on Criteria for Clinical Trials in cGVHD recommended HRQL tools as an independent measure of the impact of disease burden. The NIH recommendations did not provide a cGVHD-specific tool for HRQOL measures in children. This report focuses on the development of an SCT-specific instrument to assess HRQL in children and adolescents. For the assessment of generic HRQL we chose the PedsQL (Pediatric Quality of Life Inventory) Generic Cores Scales, which have been used in a large number of healthy, acutely ill and chronically ill children and adolescents. To capture SCT- and, specifically, cGVHD-related problems, we developed the PedsQL Stem Cell Transplant module by reviewing the literature, taking over some items/scales of other PedsQL modules, interviewing patients, parents and members of the health-care team, and applying the PedsQL measurement methods. The final PedsQL Stem Cell Transplant module consists of the HRQL domains: pain and hurt, fatigue/sleeping problems/weakness, nausea, worry/anxiety about disease/treatment, nutritional problems, neurocognitive problems, communication about disease/treatment, loneliness, physical functioning and additional somatic complaints (pruritus, skin inflammation, oral problems, eyes or breathing) including patients' and parents' assessment. It was tested in 35 pediatric patients, who were referred to our SCT Outpatient Clinic about 100 days post SCT. Both the generic PedsQL and the SCT-specific scales showed high internal consistency, with Cronbach alpha levels of ⩾0.70 in almost all scales. Most problems were detected within the HRQL domains of physical functioning and pain. The summary scores of the generic Peds

    The advent of new cell-based immunotherapies for leukemia offers treatment possibilities for certain leukemia subgroups. The wider acceptability of these new technologies in clinical practice will depend on its impact on survival and costs. Due to the small patient groups who have received it, these aspects have remained understudied. This non-randomized single-center study evaluated medical costs and survival for acute myeloid leukemia between 2005 and 2010 in 50 patients: patients treated with induction and consolidation chemotherapy (ICT) alone; patients treated with ICT plus allogeneic hematopoietic stem cell transplantation (HCT), which is the current preferred post-remission therapy in patients with intermediate- and poor-risk AML with few co-morbidities, and patients treated with ICT plus immunotherapy using autologous dendritic cells (DC) engineered to express the Wilms' tumor protein (WT1). Total costs including post- consolidation costs on medical care at the hematology ward and outpatient clinic, pharmaceutical prescriptions, intensive care ward, laboratory tests and medical imaging were analyzed. Survival was markedly better in HCT and DC. HCT and DC were more costly than ICT. The median total costs for HCT and DC were similar. These results need to be confirmed to enable more thorough cost-effectiveness analyses, based on observations from multicenter, randomized clinical trials and preferably using quality-adjusted life-years as an outcome measure.

    The study documents the risk that comes with DNA analysis of materials derived from patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in forensic genetics. DNA chimerism was studied in 30 patients after allo-HSCT, based on techniques applied in contemporary forensic genetics, i.e. real-time PCR and multiplex PCR-STR with the use of autosomal DNA as well as Y-DNA markers. The results revealed that the DNA profile of the recipient's blood was identical with the donor's in the majority of cases. Therefore, blood analysis can lead to false conclusions in personal identification as well as kinship analysis. An investigation of buccal swabs revealed a mixture of DNA in the majority of recipients. Consequently, personal identification on the basis of stain analysis of the same origin may be impossible. The safest (but not ideal) material turned out to be the hair root. Its analysis based on autosomal DNA revealed 100% of the recipient's profile. However, an analysis based on Y-chromosome markers performed in female allo-HSCT recipients with male donors demonstrated the presence of donor DNA in hair cells - similarly to the blood and buccal swabs. In the light of potential risks arising from DNA profiling of biological materials derived from persons after allotransplantation in judicial aspects, certain procedures were proposed to eliminate such dangers. The basic procedures include abandoning the approach based exclusively on blood collection, both for kinship analysis and personal identification; asking persons who are to be tested about their history of allo-HSCT before sample collection and profile entry in the DNA database, and verification of DNA profiling based on hair follicles in uncertain cases.

    Allogeneic (allo) hematopoietic cell transplantation (HCT) can induce long-term remissions in chemosensitive relapsed follicular lymphoma (FL). The Blood and Marrow Transplant Clinical Trials Network conducted a multicenter phase 2 trial to examine the efficacy of alloHCT using reduced-intensity conditioning with rituximab (RTX) in multiply relapsed, chemosensitive FL. The primary endpoint was 2-year progression-free survival (PFS). The conditioning regimen consisted of fludarabine, cyclophosphamide, and high-dose RTX (FCR), in which 3 of the 4 doses of RTX were administered at a dose of 1 gm/m(2). Graft-versus-host disease (GVHD) prophylaxis was with tacrolimus and methotrexate. Sixty-five patients were enrolled and 62 were evaluable. Median age was 55 years (range, 29 to 74). This group was heavily pretreated: 77% had received ≥ 3 prior regimens, 32% had received ≥ 5 prior regimens, and 11% had received prior autologous HCT. Donors were HLA-matched siblings (n = 33) or HLA-matched unrelated adults (n = 29). No graft failures occurred. The overall response rate after HCT was 94% with 90% in complete remission (CR), including 24 patients not in CR before alloHCT. With a median follow-up of 47 months (range, 30 to 73), 3-year PFS and overall survival rates were 71% (95% confidence interval, 58% to 81%) and 82% (95% confidence interval, 70% to 90%), respectively. Three-year cumulative incidences of relapse/progression and nonrelapse mortality were 13% and 16%, respectively. Two-year cumulative incidences of grades 2 to 4 and grades 3 or 4 acute GVHD were 27% and 10%, respectively, and extensive chronic GVHD incidence was 55%. Serum RTX concentrations peaked at day +28 and remained detectable as late as 1 year in 59% of patients with available data. In conclusion, alloHCT with FCR conditioning confers high CR rates, a low incidence of relapse/progression, and excellent survival probabilities in heavily pretreated FL patients. PMID:27118571

    Hematopoietic stem cell transplantation (HSCT) and consolidation chemotherapy have been used to treat intermediate-risk acute myeloid leukemia (AML) patients in first complete remission (CR1). However, it is still unclear which treatments are most effective for these patients. The aim of our study was to analyze the relapse-free survival (RFS) and overall survival (OS) benefit of allogeneic HSCT (alloHSCT) for intermediate-risk AML patients in CR1. A meta-analysis of prospective trials comparing alloHSCT to non-alloHSCT (autologous HSCT [autoHSCT] and/or chemotherapy) was undertaken. We systematically searched PubMed, Embase, and the Cochrane Library though October 2014, using keywords and relative MeSH or Emtree terms, ‘allogeneic’; ‘acut*’ and ‘leukem*/aml/leukaem*/leucem*/leucaem*’; and ‘nonlympho*’ or ‘myelo*’. A total of 7053 articles were accessed. The primary outcomes were RFS and OS, while the secondary outcomes were treatment-related mortality (TRM) and relapse rate (RR). Hazard ratios (HR) and 95% confidence intervals (CI) were calculated for each outcome. The primary outcomes were RFS and OS, while the secondary outcomes were TRM and RR. We included 9 prospective controlled studies including 1950 adult patients. Patients with intermediate-risk AML in CR1 who received either alloHSCT or non-alloHSCT were considered eligible. AlloHSCT was found to be associated with significantly better RFS, OS, and RR than non-alloHSCT (HR, 0.684 [95% CI: 0.48, 0.95]; HR, 0.76 [95% CI: 0.61, 0.95]; and HR, 0.58 [95% CI: 0.45, 0.75], respectively). TRM was significantly higher following alloHSCT than non-alloHSCT (HR, 3.09 [95% CI: 1.38, 6.92]). However, subgroup analysis showed no OS benefit for alloHSCT over autoHSCT (HR, 0.99 [95% CI: 0.70, 1.39]). In conclusion, alloHSCT is associated with more favorable RFS, OS, and RR benefits (but not TRM outcomes) than non-alloHSCT generally, but does not have an OS advantage over autoHSCT specifically, in

    Severe steroid-refractory acute graft-versus-host disease (aGVHD) is related to significant mortality and morbidity after allogeneic stem cell transplantation. Early clinical trials of therapy with human mesenchymal stem cells (hMSCs) in pediatric patients with severe aGVHD resistant to multiple immunosuppressive agents showed promising results. In this study, we evaluated the risk/benefit profile of remestemcel-L (Prochymal), a third-party, off-the-shelf source of hMSCs, as a rescue agent for treatment-resistant aGVHD in pediatric patients. Children with grade B-D aGVHD failing steroids and, in most cases, other immunosuppressive agents were eligible for enrollment. Patients received 8 biweekly i.v. infusions of 2 × 10(6) hMSCs/kg for 4 weeks, with an additional 4 weekly infusions after day +28 for patients who achieved either a partial or mixed response. The enrolled patients compose a very challenging population with severe disease that was nonresponsive to the standard of care, with 88% of the patients experiencing severe aGVHD (grade C or D). Seventy-five patients (median age, 8 yr; 58.7% male; and 61.3% Caucasian) were treated in this study. Sixty-four patients (85.3%) had received an unrelated hematopoietic stem cell graft, and 28 patients (37.3%) had received a cord blood graft. At baseline, the distribution of aGVHD grades B, C, and D was 12.0%, 28.0%, and 60.0%, respectively. The median duration of aGVHD before enrollment was 30 d (range, 2 to 1639 d), and patients failed a median of 3 immunosuppressive agents. Organ involvement at baseline was 86.7% gastrointestinal, 54.7% skin, and 36.0% liver. Thirty-six patients (48.0%) had 2 organs involved, and 11 patients (14.7%) had all 3 organs involved. When stratified by aGVHD grade at baseline, the rate of overall response (complete and partial response) at day +28 was 66.7% for aGVHD grade B, 76.2% for grade C, and 53.3% for grade D. Overall response for individual organs at day +28 was 58.5% for

    Allogeneic hematopoietic cell transplantation (HCT) is the only treatment able to prevent progressive neurodegenerative disease in a selected group of mucopolysaccharidosis (MPS) disorders. However, its use was historically limited by the high risk of graft failure and transplantation-related morbidity and mortality. Therefore, since 2005 new international HCT guidelines for MPS disorders were proposed. The survival and graft outcomes of MPS patients receiving HCT according to these guidelines in 2 European centers of expertise were evaluated. Two consecutive conditioning regimens were used, busulfan/cyclophosphamide or fludarabine/busulfan-based, both with exposure-targeted i.v. busulfan. A noncarrier matched sibling donor (MSD), matched unrelated cord blood (UCB), or matched unrelated donor (MUD) were considered to be preferred donors. If not available, a mismatched UCB donor was used. Participants were 62 MPS patients (56 MPS type I-Hurler, 2 MPS type II, 2 MPS type III, and 2 MPS type VI) receiving HCT at median age 13.5 months (range, 3 to 44). Forty-one patients received a UCB donor, 17 MSD, and 4 MUD. High overall survival (95.2%) and event-free survival (90.3%) were achieved with only low toxicity: 13.3% acute graft-versus-host disease aGVHD) grades II to IV and 14.8% chronic GVHD (1.9% extensive). A mismatched donor predicted for lower event-free survival (P = .04). A higher age at HCT was a predictor for both aGVHD (P = .001) and chronic GVHD (P = .01). The use of a mismatched donor was a predictor for aGVHD (P = .01). Higher rates of full-donor chimerism were achieved in successfully transplanted UCB recipients compared with MSD/MUD (P = .002). If complying with the international HCT guidelines, HCT in MPS patients results in high safety and efficacy. This allows extension of HCT to more attenuated MPS types. Because a younger age at HCT is associated with reduction of HCT-related toxicity, newborn screening may further increase safety. PMID

    Patients previously infected with hepatitis B virus (HBV) undergoing an allograft and recipients from HBV carrier donors are at risk of posttransplant viral reactivation. The role of prophylaxis with lamivudine remains unclear. One hundred seventeen patients, with a median age of 52 years (20-67 years), with various hematologic malignancies transplanted between 1999 and 2007 entered the study. Eighty-seven recipients negative for HBV surface antigen (HBsAg), antihepatitis B core antigen antibodies (anti-HBc), and HBV-DNA with HBsAg and HBV-DNA negative donors were defined as at low risk of HBV reactivation, whereas all the remaining 30 patients were defined as at high risk. Patients at high risk transplanted in 2005 or after received lamivudine to prevent HBV reactivation as per the Italian guidelines by the Associazione Italiana per lo Studio del Fegato (AISF). Patients at low risk did not experience HBV reactivation/hepatitis. Among the recipients at high risk, 11 of 25 anti-HBc positive, those HBsAg positive (2 of 2) or negative but transplanted from HBsAg positive donors (3 of 3) were treated with lamivudine. None of these developed HBV reactivation/hepatitis after a median follow-up of 40 months (17-55 months). Hepatitis developed in 3 anti-HBc positive untreated patients conditioned with a reduced-intensity regimen. Hepatitis B was not observed in recipients at low risk, transplanted from HBsAg negative/anti-HBc positive or negative donors. Lamivudine was effective in controlling reactivation in: HBsAg positive recipients, in patients transplanted from HBsAg positive donors and in HBsAg negative/antiHBc positive recipients, who showed a significant risk of reactivation if not given prophylaxis (NCT 00876148).

    During allogeneic hematopoietic cell transplantation (alloHCT), nonhematopoietic cell interleukin-33 (IL-33) is augmented and released by recipient conditioning to promote type 1 alloimmunity and lethal acute graft-versus-host disease (GVHD). Yet, IL-33 is highly pleiotropic and exhibits potent immunoregulatory properties in the absence of coincident proinflammatory stimuli. We tested whether peri-alloHCT IL-33 delivery can protect against development of GVHD by augmenting IL-33-associated regulatory mechanisms. IL-33 administration augmented the frequency of regulatory T cells (Tregs) expressing the IL-33 receptor, suppression of tumorigenicity-2 (ST2), which persist following total body irradiation. ST2 expression is not exclusive to Tregs and IL-33 expands innate immune cells with regulatory or reparative properties. However, selective depletion of recipient Foxp3(+) cells concurrent with peri-alloHCT IL-33 administration accelerated acute GVHD lethality. IL-33-expanded Tregs protected recipients from GVHD by controlling macrophage activation and preventing accumulation of effector T cells in GVHD-target tissue. IL-33 stimulation of ST2 on Tregs activates p38 MAPK, which drives expansion of the ST2(+) Treg subset. Associated mechanistic studies revealed that proliferating Tregs exhibit IL-33-independent upregulation of ST2 and the adoptive transfer of st2(+) but not st2(-) Tregs mediated GVHD protection. In total, these data demonstrate the protective capacity of peri-alloHCT administration of IL-33 and IL-33-responsive Tregs in mouse models of acute GVHD. These findings provide strong support that the immunoregulatory relationship between IL-33 and Tregs can be harnessed therapeutically to prevent GVHD after alloHCT for treatment of malignancy or as a means for tolerance induction in solid organ transplantation.

    Purpose: Total-body irradiation (TBI) has an important role in patients undergoing hematopoietic cell transplantation (HCT), but is associated with significant toxicities. Targeted TBI using helical tomotherapy results in reduced doses to normal organs, which predicts for reduced toxicities compared with standard TBI. Methods and Materials: Thirteen patients with multiple myeloma were treated in an autologous tandem transplantation Phase I trial with high-dose melphalan, followed 6 weeks later by total-marrow irradiation (TMI) to skeletal bone. Dose levels were 10, 12, 14, and 16 Gy at 2 Gy daily/twice daily. In a separate allogeneic HCT trial, 8 patients (5 with acute myelogenous leukemia, 1 with acute lymphoblastic leukemia, 1 with non-Hodgkin's lymphoma, and 1 with multiple myeloma) were treated with TMI plus total lymphoid irradiation plus splenic radiotherapy to 12 Gy (1.5 Gy twice daily) combined with fludarabine/melphalan. Results: For the 13 patients in the tandem autologous HCT trial, median age was 54 years (range, 42-66 years). Median organ doses were 15-65% that of the gross target volume dose. Primarily Grades 1-2 acute toxicities were observed. Six patients reported no vomiting; 9 patients, no mucositis; 6 patients, no fatigue; and 8 patients, no diarrhea. For the 8 patients in the allogeneic HCT trial, median age was 52 years (range, 24-61 years). Grades 2-3 nausea, vomiting, mucositis, and diarrhea were observed. In both trials, no Grade 4 nonhematologic toxicity was observed, and all patients underwent successful engraftment. Conclusions: This study shows that TMI using helical tomotherapy is clinically feasible. The reduced acute toxicities observed compare favorably with those seen with standard TBI. Initial results are encouraging and warrant further evaluation as a method to dose escalate with acceptable toxicity or to offer TBI-containing regimens to patients unable to tolerate standard approaches.

    A major hypothesis to explain the immunodeficiency associated with bone marrow transplantation states that thymic epithelial damage due to graft-versus-host disease (GVHD) abrogates or delays the recovery of normal immunologic function. This study evaluated the thymus glands of 36 human bone marrow transplant recipients dying between 4 and 1742 days after transplant using histology, histochemistry, and immunohistology. The observations lead to a model of thymic damage by irradiation, chemotherapy, and GVHD in which early injury by all three of these agents results in profound thymic atrophy followed by long-delayed restitution. Patients undergoing total body irradiation showed more severe damage to thymic cortical and medullary epithelium than did patients undergoing chemotherapy alone as preparation for transplantation. Patients with GVHD showed additional damage in the form of individual thymic epithelial cell death and showed HLA-DR surface protein expression on thymic epithelium during GVHD. Longer-term survivors showed a profoundly delayed restitution of normal thymic epithelium and delayed evidence of restored lymphopoiesis. A few patients dying late after transplant showed evidence of reconstitution of normal thymic structure or nodules of lymphopoiesis in focal areas of epithelial-cell reconstitution. Evidence of such lymphopoiesis was seen at times ranging between 90 and 1742 days after grafting. The data are consistent with a model of long-standing thymic damage caused by GVHD which is reversible after the development of tolerance.

    In 1998, the Tunisian team of the 'Centre National de Greffe de Moelle Osseuse' initiated allogeneic hematopoietic SCT (AHSCT) in Tunisia. As of June 2007, information was collected about 299 patients with a first AHSCT and 12 additional retransplants. The median age was 19 years (range 2-49 years). The main indications were aplastic anemia (n=106, 36%), leukemia and nonmalignant disorders (n=153, 51%), Fanconi anemia (n=26, 9%) and other nonmalignant disorders (n=14, 4%). Preparative regimens depended on indication. All donors were HLA geno-identical. The stem cell sources were BM (87%) and PBSCs (13%). At the time of analysis, 200 patients (67%) were alive after a median follow-up of 42 months (range 3-112 months). The overall TRM rate was 17%. Outcome depended on indication. According to our results, allogeneic HSCT is potentially curative for hematological diseases, but it is a toxic approach for malignant disorders. PMID:18724288

    Systems that evolve over time and follow mathematical laws as they evolve are called dynamical systems. Lymphocyte recovery and clinical outcomes in 41 allograft recipients conditioned using antithymocyte globulin (ATG) and 4.5-Gy total body irradiation were studied to determine if immune reconstitution could be described as a dynamical system. Survival, relapse, and graft-versus-host disease (GVHD) were not significantly different in 2 cohorts of patients receiving different doses of ATG. However, donor-derived CD3(+) cell reconstitution was superior in the lower ATG dose cohort, and there were fewer instances of donor lymphocyte infusion (DLI). Lymphoid recovery was plotted in each individual over time and demonstrated 1 of 3 sigmoid growth patterns: Pattern A (n = 15) had rapid growth with high lymphocyte counts, pattern B (n = 14) had slower growth with intermediate recovery, and pattern C (n = 10) had poor lymphocyte reconstitution. There was a significant association between lymphocyte recovery patterns and both the rate of change of donor-derived CD3(+) at day 30 after stem cell transplantation (SCT) and clinical outcomes. GVHD was observed more frequently with pattern A, relapse and DLI more so with pattern C, with a consequent survival advantage in patients with patterns A and B. We conclude that evaluating immune reconstitution after SCT as a dynamical system may differentiate patients at risk of adverse outcomes and allow early intervention to modulate that risk.

    Despite the overall benefit from allogeneic hematopoietic stem cell transplantation observed in patients with poor cytogenetic risk acute myeloid leukemia in first complete remission, the precise effect of this procedure for different poor-risk subtypes has not been fully analyzed. This retrospective analysis was performed to investigate whether allogeneic hematopoietic stem cell transplantation performed in first complete remission in patients with monosomal karyotype can overcome the adverse prognosis associated with these patients. Of the 4635 patients included in the study, 189 (4%) harbored a monosomal karyotype. The presence of a monosomal karyotype was associated with a worse outcome, with an inferior leukemia-free survival and overall survival (5-year leukemia-free survival and overall survival: 24±3% and 26±3% vs. 53±1% and 57±1% in monosomal-karyotype and non-monosomal-karyotype, respectively; P<0.0001) and higher relapse risk after transplantation (cumulative incidence of relapse at 5 years: 56±4% in monosomal-karyotype vs. 28±1% in non-monosomal-karyotype; P<0.0001). The adverse negative impact of monosomal karyotype cytogenetics was confirmed in the entire cohort in a multivariate analysis [Hazard Ratio (HR): 1.88, 95% Confidence Interval (CI):1.29–2.73, P=0.001 for relapse incidence; HR:1.71, 95%CI:1.27–2.32, P<0.0001 for leukemia-free survival; HR:1.81, 95%CI:1.32–2.48, P=0.0002 for overall survival], and was independent of the presence of other poor-risk cytogenetic subtypes. In summary, monosomal karyotype arises as a strong negative prognostic feature in acute myeloid leukemia also in patients who undergo allogeneic hematopoietic stem cell transplantation in first complete remission, stressing the need to develop additional pre- and post-transplantation strategies aimed at improving overall results. Nonetheless, allogeneic hematopoietic stem cell transplantation in early phase is currently the best therapy for this very poor-risk acute

    Allogeneic hematopoietic stem cell transplantation (HCT) is a well-established treatment for many malignant and non-malignant hematological disorders. As frequent complication in up to 50 % of all patients, graft-versus-host disease (GVHD) is still the main cause for morbidity and non-relapse mortality. Diagnosis of GVHD is usually done clinically, even though confirmation by pathology is often used to support the clinical findings. Effective treatment requires intensified immunosuppression as early as possible. Although several promising biomarkers have been proposed for an early diagnosis, no internationally recognized consensus has yet been established. Here, microRNAs (miRs) represent an interesting tool since miRs have been recently reported to be an important regulator of various cells, including immune cells such as T cells. Therefore, we could assume that miRs play a key role in the pathogenesis of acute GVHD, and their detection might be an interesting possibility in the early diagnosis and monitoring of acute GVHD. Recent studies additionally demonstrated the implication of miRs in the pathogenesis of acute GVHD. In this review, we aim to summarize the previous reports of miRs, focusing on the pathogenesis of acute GVHD and possible implications in diagnostic approaches. PMID:25900787

    Non-Hodgkin lymphomas (NHL) disproportionately affect older patients who uncommonly receive allogeneic hematopoietic cell transplantation (HCT). We analyzed CIBMTR data on 1248 patients ≥40 years receiving reduced-intensity conditioning (RIC) or non-myeloablative (NMA) HCT for aggressive (n=668) and indolent (n=580) NHL. Aggressive lymphoma was more frequent in the oldest cohort [(age 40–54) 49% vs. (55–64) 57% vs. (≥65) 67% p=0.0008]; fewer patients ≥65 had prior autografting [26% vs. 24% vs. 9%; p=0.002)]. Rates of relapse, acute and chronic GVHD and non-relapse mortality (NRM) at one year were similar [22%, 95% confidence interval (CI) 19–26%; 27%, 95% CI 23–31%; 34%, 95% CI 24–44%]. Progression-free (PFS) and overall (OS) survival at 3 years was slightly lower in older cohorts [OS:54%, 95% CI 50–58%; 40%, 95% CI 36–44%; 39%, 95% CI 28–50%; p<0.0001]. Multivariate analysis revealed no significant effect of age on acute or chronic GVHD or relapse. Age ≥55 years, Karnofsky performance status <80, and HLA-mismatch adversely impacted NRM, PFS, and OS. Disease status at HCT, but not histologic subtype, worsened NRM, relapse, PFS and OS. Even for patients ≥55 years, OS still approached 40% at 3 years suggesting HCT effects long-term remissions and remains underutilized in qualified older patients with NHL. PMID:24641829

    Summary Graft-versus-host disease (GVHD) is partly mediated by host antigen presenting cells (APCs) that activate donor T-cells. Extracorporeal photopheresis (ECP) can modulate APC function and benefit some patients with GVHD. We report the results of a study using ECP administered prior to a standard myeloablative preparative regimen intended to prevent GVHD. Grade II-IV aGVHD developed in 9 (30%) of 30 recipients of HLA-matched related transplants and 13 (42%) of 31 recipients of HLA-matched unrelated or HLA-mismatched related donor transplants. Actuarial estimates of overall survival (OS) at day 100 and 1 year post transplant were 89% (95% CI, 78%-94%) and 77% (95% CI, 64%-86%), respectively. There were no unexpected adverse effects of ECP. Historical controls receiving similar conditioning and GVHD prophylaxis regimens but no ECP were identified from the database of the Center for International Blood and Marrow Transplant Research and multivariate analysis indicated a lower risk of grade II-IV aGVHD in patients receiving ECP (p=0.04). Adjusted OS at one year was 83% in the ECP study group and 67% in the historical control group (relative risk 0.44, 95% CI, 0.24-0.80) (p= 0.007). These preliminary data may indicate a potential survival advantage with ECP for transplant recipients undergoing standard myeloablative hematopoietic cell transplantation. PMID:19915634

    Mycosis Fungoides is typically an indolent disease in early stages. However, approximately 30% of patients have advanced staged disease at presentation and 20% will develop it at some time. These patients have a poorer prognosis with a median survival of 2-4 years. The only curative option for mycosis fungoides may be hematopoietic allogeneic stem cell transplantation. We report the case of a patient with mycosis fungoides in an advanced stage (IIB), refractory to treatment options. She underwent allogeneic hematopoietic stem-cell transplantation (allo-HSCT). The patient remains in complete remission nineteen months after allo-HSCT. Allogeneic transplantation can alter the natural history of mycosis fungoides and should be considered in patients who have refractory disease or short-lived responses with standard therapies.

    The prognostic significance of molecular mutations (FLT3-ITD, NPM1, and CEBPA mutations) was examined in patients with normal-karyotype acute myeloid leukaemia (NK-AML) after allogeneic haematopoietic cell transplantation (HCT). In total, 115 patients received allogeneic HCT for NK-AML and were evaluated for FLT3-ITD, NPM1, and CEBPA mutations in diagnostic samples and for long-term outcomes following HCT, retrospectively. The prevalences of FLT3-ITD(pos), NPM1 (mut), and CEBPA (dm) (double mutations) were 32.2, 43.5, and 24.6 %, respectively. The triple-negative group (NPM1 (wild)/FLT3-ITD(neg)/non-CEBPA (dm)) showed a similar transplant outcome to those in the favourable European LeukemiaNet (ELN) risk group for overall survival (OS) (60.9 vs. 63.7 %; p = 0.810), but a more favourable OS than others in the intermediate-I risk group (40.0 %; p = 0.034). Also, the triple-negative group showed a similar relapse rate at 5 years compared with those in the favourable risk group (9.7 vs. 15.5 %; p = 0.499), but a lower rate of relapse than the others in the intermediate-I risk group (15.5 vs. 48.6 %; p = 0.004). The 5-year relapse incidences were 4.0 % (NPM1 (mut)/FLT3-ITD(neg)), 14.7 % (CEBPA (dm)), 15.5 % (NPM1 (wild)/FLT3-ITD(neg)/non-CEBPA (dm)), 39.1 % (NPM1 (mut)/FLT3-ITD(pos)/non-CEBPA (dm)), and 66.7 % (NPM1 (wild)/FLT3-ITD(pos)/non-CEBPA (dm)). Thus, the triple-negative (NPM1 (wild)/FLT3-ITD(neg)/non-CEBPA (dm)) group showed favourable long-term outcomes after allogeneic HCT in NK-AML, similar to those of the favourable risk group by the ELN risk classification.

    Myeloid sarcoma is a solid, extramedullary tumor comprising of immature myeloid cells. It may occur in any organ; however, the invasion of peripheral nervous system is rare. Herein, we report the case of myeloid sarcoma on the brachial plexus. A 37-year-old woman with acute myelogenous leukemia achieved complete remission after chemotherapy. One year later, she presented right shoulder pain, progressive weakness in the right upper extremity and hypesthesia. Based on magnetic resonance images (MRI) and electrophysiologic study, a provisional diagnosis of brachial plexus neuritis was done and hence steroid pulse therapy was carried out. Three months later the patient presented epigastric pain. After upper gastrointestinal endoscopy, myeloid sarcoma of gastrointestinal tract was confirmed pathologically. Moreover, 18-fluoride fluorodeoxyglucose positron emission tomography showed a fusiform shaped mass lesion at the brachial plexus overlapping with previous high signal lesion on the MRI. Therefore, we concluded the final diagnosis as brachial plexopathy due to myeloid sarcoma. PMID:23705126

    The multikinase inhibitor sorafenib has shown a strong anti-leukemic effect in FMS-like tyrosine kinase 3 (FLT3)-mutated acute myeloid leukemia (AML); however, remission is often transient. To better understand the role of sorafenib, we performed a retrospective analysis of all patients who received sorafenib in combination with allogeneic hematopoietic stem cell transplantation (HSCT) at our center. Seventeen patients with FLT3-ITD positive AML were treated with sorafenib in combination with allogeneic HSCT. Seven patients received sorafenib therapy pre- and posttransplant, and 10 patients were given sorafenib only posttransplant. Median duration of sorafenib treatment was 13 months (range 1-42); median dose was 600 mg (range 100-1200). Fourteen patients (82 %) achieved a complete remission (CR), while 5 patients (29 %) eventually developed progressive disease. Developing chronic graft-versus-host disease (GvHD) had a strong protective influence on the risk of sorafenib resistance (p = 0.028, HR 0.08, 95 % CI 0.01-0.76). In a total of 8 patients, sorafenib had to be stopped, paused or dose-reduced due to toxicity. In 5 patients with pronounced toxicity, we switched to an alternating dosing schedule with 1 month on/1 month off sorafenib. These patients subsequently remained in sustained complete molecular remission, with a median follow-up of 20 months. Our data indicate that sorafenib can achieve high rates of sustained remission in high-risk patients treated in combination with HSCT. PMID:26233683

    Frailty is a syndrome associated with reduced physiological reserves that increases an individual's vulnerability for developing increased morbidity and/or mortality. While most clinical trials have focused on exercise, nutrition, pharmacologic agents, or a multifactorial approach for the prevention and attenuation of frailty, none have studied the use of cell-based therapies. We hypothesize that the application of allogeneic human mesenchymal stem cells (allo-hMSCs) as a therapeutic agent for individuals with frailty is safe and efficacious. The CRATUS trial comprises an initial non-blinded phase I study, followed by a blinded, randomized phase I/II study (with an optional follow-up phase) that will address the safety and pre-specified beneficial effects in patients with the aging frailty syndrome. In the initial phase I protocol, allo-hMSCs will be administered in escalating doses via peripheral intravenous infusion (n=15) to patients allocated to three treatment groups: Group 1 (n=5, 20 million allo-hMSCs), Group 2 (n=5, 100 million allo-hMSCs), and Group 3 (n=5, 200 million allo-hMSCs). Subsequently, in the randomized phase, allo-hMSCs or matched placebo will be administered to patients (n=30) randomly allocated in a 1:1:1 ratio to one of two doses of MSCs versus placebo: Group A (n=10, 100 million allo-hMSCs), Group B (n=10, 200 million allo-hMSCs), and Group C (n=10, placebo). Primary and secondary objectives are, respectively, to demonstrate the safety and efficacy of allo-hMSCs administered in frail older individuals. This study will determine the safety of intravenous infusion of stem cells and compare phenotypic outcomes in patients with aging frailty. PMID:26933813

    Myeloproliferative neoplasms (MPN) are chronic marrow disorders with variable prognoses. Most patients with polycythemia vera, essential thrombocythemia, or even primary myelofibrosis (PMF) are successfully treated with conservative strategies for years or even decades, and recent data suggest that even in patients with high-risk disease, in particular those with PMF, life expectancy can be extended by treatment with janus kinase (JAK2) inhibitors. However, none of those modalities are curative, and after marrow failure develops, the disease "accelerates," or transforms to acute leukemia, the only option able to effectively treat and, in fact, cure MPN is allogeneic hematopoietic cell transplantation (HCT). Outcome is superior if HCT is performed before leukemic transformation occurs. Several reports document survival in unmaintained remission beyond 10 years. The most recent analyses show reduced regimen-related mortality (less than 10% or even 5% at day 100) and progressively improved survival with both HLA-identical sibling and unrelated donors. The development of low/reduced-intensity conditioning regimens has contributed to the improved success rate and has allowed successful HCT in patients in their seventh and even eighth decade of life. We propose, therefore, that HCT should be offered to fit patients in these age groups and should be covered by their respective insurance carriers. PMID:26371371

    We conducted a phase 2 study to determine the efficacy of HLA-haploidentical related donor natural killer (NK) cells after cyclophosphamide-based lymphodepletion in patients with relapsed or progressive acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS) following allogeneic hematopoietic cell transplantation (HCT). Eight patients (2 with MDS and 6 with AML) were treated with cyclophosphamide 50 mg/kg on day -3 and day -2 before infusion of NK cells isolated from a haploidentical related donor. One patient also received fludarabine 25 mg/m(2)/day for 4 days. Six doses of 1 million units of interleukin-2 (IL-2) were administered on alternating days beginning on day -1. The median number of NK cells infused was 10.6 × 10(6)/kg (range, 4.3 to 22.4 × 10(6)/kg), and the median number of CD3 cells infused was 2.1 × 10(3)/kg (range, 1.9 to 40 × 10(3)/kg). NK infusions were well tolerated, with a median time to neutrophil recovery of 19 days (range, 7 days to not achieved) and no incidence of graft-versus-host disease after NK infusion. One patient with AML and 1 patient with MDS achieved a complete response, but relapsed at 1.7 and 1.8 months, respectively. One patient with MDS experienced resolution of dysplastic features but persistence of clonal karyotype abnormalities; this patient was stable at 65 months after NK cell therapy. The median duration of survival was 12.9 months (range, 0.8 to 65.3 months). Chimerism analysis of CD3(-)/CD56(+) peripheral blood cells did not detect any circulating haploidentical NK cells after infusion. NK phenotyping was performed in 7 patients during and after IL-2 infusion. We found a slight trend toward greater expression of KIR2DL2/2DL3/2DS2 (5% versus 28%; P = .03) at 14 days in patients who survived longer than 6 months from NK cell infusion (n = 4) compared with those who died within 6 months of NK cell therapy (n = 3).

    Human recombinant granulocyte colony-stimulating factor (G-CSF), filgrastim (Neupogen; Amgen, Thousand Oaks, CA, USA), has been widely used for the mobilization of CD34(+) hematopoietic stem cells (HSC) from healthy donors. The experience with biosimilar G-CSF agents in this area is limited. We performed a prospective study assessing Tevagrastim (biosimilar filgrastim, XMO2; Teva, Israel) for mobilization of CD34(+) peripheral blood HSC in HLA-matched healthy sibling donors for transplantation in 24 patients with acute myelogenous leukemia (AML) and high-risk myelodysplastic syndromes (MDS) (NCT01542944). Results were compared to a historical control group of sibling donors who received filgrastim for stem cell mobilization for allogeneic stem cell transplantations in patients with AML and MDS. The healthy donors received Tevagrastim or filgrastim in a dose of 10 μg/kg body weight (BW) subcutaneously for 4 days. The target yields of CD34(+) cells was 5 × 10(6) CD34(+) cells/kg BW of the recipient. A median 10.2 × 10(6) (range, 2.52 to 35.4) and 9.35 × 10(6) (range, 3.7 to 30.6) CD34(+) cells per kg BW were collected in the Tevagrastim and filgrastim groups, respectively. All patients promptly engrafted with a median day of absolute neutrophil count (ANC) of >.5 × 10(9)/L and >1 × 10(9)/L of 13 days (range, 10 to 21) and 13.5 days (range, 10 to 22), respectively in the Tevagrastim group and 12 days (range, 10 to 18) and 13 days (range, 10 to 18) in the filgrastim group, respectively. Platelets reached counts of >20 × 10(9)/L and >50 × 10(9)/L within a median of 14 days (range, 11 to 33) and 17 days (range, 12 to 33) in the Tevagrastim group and 13 (range, 10 to 29) and 15 (range, 10 to 32) days in the filgrastim group, respectively. The donors developed only mild and transient side effects, which were not different between the Tevagrastim study group and the filgrastim historical control group. Similarly, the transplantation-related toxicities

    Allogenic bone screws are new to the fixation market and have yet to be tested against current fixation materials. An in vitro comparison of the same sizes of stainless steel, bioabsorbable, and allogenic bone screws was undertaken to assess screw resistance to the forces of bending, pullout, and shear. Using aluminum plates to support the screws, forces up to 1000 Newtons were applied to six to eight samples of each type of screw. During each test, stainless steel screws withstood the maximum force that could be exerted by the testing apparatus without failing (bending, 113.9 +/- 11.8 N mean +/- SE; pullout 999.1 +/- 33.7 N; and shear, 997.5 +/- 108.8 N). In each test, compared to bioabsorbable screws, allogenic bone screws failed faster (pullout, allogenic: 12.4 +/- 1.1 seconds vs. bioabsorbable, 120.6 +/- 13.8 seconds; p = .001; bending, allogenic: 53.4 +/- 4.8 seconds vs. bioabsorbable, 201.9 +/- 11.1 seconds; p = .001; shear, allogenic 13.5 +/- 1.4 seconds vs. bioabsorbable, 43.8 +/- 0.9 seconds; p = .001) under equivalent (pullout: bioabsorbable, 385.0 +/- 18.4 N vs. allogenic, 401.0 +/- 35.9 N; p = .001) or lower (bending, allogenic: 4.7 +/- 0.2 N vs. bioabsorbable, 11.0 +/- 0.9 N; p = .675; shear, allogenic: 312.1 +/- 15.5 N vs. bioabsorbable 680.9 +/- 8.5 N; p = .001) loads, and in a highly variable fashion. Overall, the bioabsorbable screws withstood the forces of bending, pullout, and shear better than the allogenic screws, and stainless steel screws outperformed both bioabsorbable and allogenic screws. Despite these results, allogenic screws could still be useful in compliant patients who would benefit from their osteoconductive properties. PMID:11858609

    The safety and efficacy of a 4-day myeloablative conditioning (MAC) regimen consisting of Bu 3.2 mg/kg and fludarabine 40 mg/m(2)/day for HLA-identical sibling allogeneic hematopoietic cell transplantation (HCT) in myeloid malignancies was investigated in 133 patients (median age, 47 years; range 19-74 years) with de novo AML (60%), secondary AML (20%) or myelodysplastic syndrome (20%). All patients engrafted. Hepatic veno-occlusive disease occurred in five patients (4%), and severe toxicities, mostly mucositis, occurred in twenty-three (17%) patients. The non-relapse mortality (NRM) at 100 days was 1.5%. The incidences of acute GVHD grade 2-4 and grade 3-4 were 32 and 13%, respectively. At a median follow-up of 38 months, the cumulative incidence of chronic GVHD was 67%. The relapse incidence was 30% (27 and 31%, respectively, in patients with early- and late-stage disease), and the overall NRM was 15%. The actuarial 4-year disease-free survival (DFS) and overall survival (OS) were 54 and 62%, respectively. Patients aged <50 years had better outcomes compared with older patients (DFS 64 vs 42%, P=0.006; OS 73 vs 47%, P<0.001, respectively). PMID:26950372

    We reported that IL-2 activated autologous NK cells can induce, but not maintain durable remissions in lymphoma patients. We hypothesized that allogeneic NK cells may overcome class I MHC-mediated inhibition of NK cell killing. In a pilot study we evaluated infusion of haploidentical donor NK cells for anti-tumor efficacy. Six patients with advanced B-cell non-Hodgkin lymphoma (NHL) received rituximab, cyclophosphamide, and fludarabine as immunosupression to permit homeostatic NK cell expansion, followed by CD3-depleted NK cell enriched cell products followed by subcutaneous IL-2 administration (10×106 units every other day × 6 doses). At 2 months, four patients showed an objective clinical response. We observed early donor cell persistence in 2 patients (blood and in tumor-bearing node), but this was not detectable beyond 7 days. All patients demonstrated substantial increases in host regulatory T cells (Treg) after NK cell and IL-2 therapy (180±80 cells/μl vs baseline: 58±24 cells/μl, p=0.04) which may have limited donor cell expansion in vivo. These findings suggest safety and feasibility of allogeneic NK cell therapy in patients with lymphoma; however host Treg and inadequate immunodepletion may contribute to a hostile milieu for NK cell survival and expansion. Cell therapy trials should incorporate novel strategies to limit Treg expansion. PMID:20680271

    Transplant recipients have been reported to have an increased risk of solid cancers but most studies are small and have limited ability to evaluate the interaction of host, disease, and treatment-related factors. In the largest study to date to evaluate risk factors for solid cancers, we studied a multi-institutional cohort of 28 874 allogeneic transplant recipients with 189 solid malignancies. Overall, patients developed new solid cancers at twice the rate expected based on general population rates (observed-to-expected ratio 2.1; 95% confidence interval 1.8-2.5), with the risk increasing over time (P trend < .001); the risk reached 3-fold among patients followed for 15 years or more after transplantation. New findings showed that the risk of developing a non–squamous cell carcinoma (non-SCC) following conditioning radiation was highly dependent on age at exposure. Among patients irradiated at ages under 30 years, the relative risk of non-SCC was 9 times that of nonirradiated patients, while the comparable risk for older patients was 1.1 (P interaction < .01). Chronic graft-versus-host disease and male sex were the main determinants for risk of SCC. These data indicate that allogeneic transplant survivors, particularly those irradiated at young ages, face increased risks of solid cancers, supporting strategies to promote lifelong surveillance among these patients.

    We have recently described a specialized subset of human natural killer (NK) cells with a CD56(dim)CD57(+)NKG2C(+) phenotype that expand specifically in response to cytomegalovirus (CMV) reactivation in hematopoietic cell transplant (HCT) recipients and exhibit properties characteristic of adaptive immunity. We hypothesize that these cells mediate relapse protection and improve post-HCT outcomes. In 674 allogeneic HCT recipients, we found that those who reactivated CMV had lower leukemia relapse (26% (17-35%), P=0.05) and superior disease-free survival (DFS) (55% (45-65%) P=0.04) 1 year after reduced intensity conditioning (RIC) compared with CMV seronegative recipients who experienced higher relapse rates (35% (27-43%)) and lower DFS (46% (38-54%)). This protective effect was independent of age and graft-vs-host disease and was not observed in recipients who received myeloablative regimens. Analysis of the reconstituting NK cells demonstrated that CMV reactivation is associated with both higher frequencies and greater absolute numbers of CD56(dim)CD57(+)NKG2C(+) NK cells, particularly after RIC HCT. Furthermore, expansion of these cells at 6 months posttransplant independently trended toward a lower 2-year relapse risk. Together, our data suggest that the protective effect of CMV reactivation on posttransplant relapse is in part driven by adaptive NK cell responses. PMID:26416461

    Allogeneic hematopoietic stem-cell transplantation (HSCT) is the most effective approach for many patients with hematologic malignancies. Unfortunately, relapse remains the most common cause of death after allogeneic HSCT, and the prognosis of relapsed disease is poor for most patients. Induction of a graft-versus-leukemia (GVL), or graft-versus-tumor, effect through the use of donor leukocyte infusion (DLI), or donor lymphocyte infusion, has been remarkably successful for relapsed chronic myelogenous leukemia. Unfortunately, response to DLI in other hematologic malignancies is much less common and depends on many factors including histology, pace and extent of relapse, and time from HSCT to relapse. Furthermore, graft-versus-host disease (GVHD) is common after DLI and often limits successful immunotherapy. Ultimately, manipulations to minimize GVHD while preserving or enhancing GVL are necessary to improve outcomes for relapse after allogeneic HSCT. PMID:23556106

    The reactivation of human herpesvirus-6B (HHV-6B) is common after allogeneic hematopoietic cell transplantation (allo-HCT), and it is sporadically associated with the development of HHV-6 encephalitis. HHV-6 encephalitis typically develops around 2-6 weeks after allo-HCT, and it is characterized by short-term memory loss. Magnetic resonance imaging typically shows bilateral signal abnormalities in the limbic system. The incidence of HHV-6 encephalitis is reportedly 0-11.6% after bone marrow or peripheral blood stem cell transplantation and 4.9-21.4% after cord blood transplantation. The mortality of HHV-6 encephalitis is high, and survivors are often left with serious sequelae. Antiviral therapy using foscarnet or ganciclovir is recommended for the treatment of HHV-6 encephalitis, but the efficacy of the currently available treatment is insufficient once HHV-6 encephalitis has developed. The elucidation of the pathogenesis of HHV-6 encephalitis and the establishment of preventative therapy are needed to overcome this disease. PMID:26160819

    Objective We sought to determine if serum citrulline (CIT), an amino acid produced by small bowel enterocytes, was associated with clinical and biochemical markers of gastrointestinal function in children undergoing hematopoietic cell transplantation (HCT). Methods We conducted a multi-center, prospective cohort study of 26 children to define time-related changes in serum CIT over the course of HCT. Markers of gastrointestinal function including oral energy intake, emesis, stool volume, presence of graft-versus-host disease (GVHD), oral mucositis severity, and cytokine and neurohormone levels were measured. Weekly serum CIT concentrations were obtained from 10 days prior until 30 days after HCT. Results Mean baseline CIT concentration was 22.7 µmol/L (95% CI 17.7 – 27.6) on day −10, which decreased to a nadir of 7.5 µmol/L (95% CI 3.1 – 18.0, p = 0.017) on day +8 following HCT before returning to baseline by day 30. After adjustment for IL-6 level (1.0% lower CIT per 10% increase in IL-6, p=0.004), presence of acute graft-versus-host disease (GVHD), (27% lower CIT, p=0.025) and oral energy intake (2.1% lower CIT per 10% decrease in energy intake, p=0.018), the nadir shifted to day +10, when mean CIT concentration was lower in patients with severe oral mucositis (6.7 µmol/L, 95% CI 3.4–13.1) than in those without severe mucositis (11.9 µmol/L, 95% CI 5.8–24.4, p=0.003). Change in CIT was not correlated with stool volume, C-reactive protein, TNF-alpha, leptin, or ghrelin. Conclusion In children undergoing HCT, serum CIT correlates with measures of gastrointestinal function (oral mucositis severity, dietary intake, acute GVHD) and may reflect mucosal injury to the gastrointestinal tract.

    A 15-year-old girl with acute lymphoblastic leukemia received allogeneic dendritic cell vaccination, pulsed with Wilms tumor 1 (WT1) peptide, after her third hematopoietic stem cell transplantation (HSCT). The vaccines were generated from the third HSCT donor, who was her younger sister, age 12 years. The patient received 14 vaccines and had no graft-versus-host disease or systemic adverse effect, aside from grade 2 skin reaction at the injection site. WT1-specific immune responses were detected after vaccination by both WT1-tetramer analysis and enzyme-linked immunosorbent spot assay. This strategy may be safe, tolerable and even feasible for patients with a relapse after HSCT. PMID:25484308

    Oral mucositis is an important side effect of hematopoietic stem cell transplantation (HCST), mainly due to toxicity of conditioning regimens. It produces significant pain and morbidity. The present study reports a prospective, randomized, non-blinded study testing the efficacy of a new mouthwash, called Baxidil Onco® (Sanitas Farmaceutici Srl, Tortona, Italy) in 60 hematologic patients undergoing HCST (28 autologous, 32 allogeneic). Baxidil Onco®, used three times a day from Day -1 to Day +30, in addition to standard prophylactic schedules, was administered to 14 patients undergoing autologous and 14 patients undergoing allogeneic HCST. The remaining 32 patients (14 autologous and 18 HCST) were treated only with standard prophylactic schedules and served as control. In our study, the overall incidence of oral mucositis, measured according to the World Health Organization 0-4 scale, was 50% in the Baxidl Onco® group versus 82% in the control group (P=0.022). In addition, a significant reduction in scale 2-4 oral mucositis was observed in the Baxidil Onco® group (25% vs 56.2%; P=0.0029). The results obtained indicate that incidence, severity and duration of oral mucositis induced by conditioning regimens for HCST can be significantly reduced by oral rinsing with Baxidil Onco®, in addition to the standard prophylaxis scheme. Since Camelia Sinensin extract, which is used to produce green tea, is the main agent in this mouthwash, we hypothesize that the anti-oxidative properties of polyphenolic compounds of tea might exert protective effects on oral mucosa.

    Clofarabine has potent antileukemia activity and its inclusion in reduced-intensity conditioning (RIC) allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia could potentially improve outcomes. We conducted a phase II study of busulfan (.8 mg/kg i.v. twice daily on days -5, -4, -3, and -2) with clofarabine (40 mg/m(2) i.v. daily on days -5, -4, -3, and -2) conditioning before allogeneic 8/8 HLA-matched related or unrelated HSCT. The primary endpoint was donor neutrophil engraftment by day +40. Secondary endpoints included nonrelapse mortality (NRM), acute and chronic graft-versus-host disease (GVHD), progression-free survival (PFS), and overall survival (OS). Thirty-four patients (acute myeloid leukemia [AML], n = 25; myelodysplastic syndromes, n = 5; and acute lymphoid leukemia, n = 4) were enrolled. Day 40+ engraftment with donor chimerism was achieved in 33 of 34 patients with 1 patient dying before count recovery. Day 100 and 1-year NRM were 5.9% (95% confidence interval [CI], 1.0 to 17.4) and 24% (95% CI, 11 to 39), respectively. The 2-year relapse rate was 26% (95% CI, 13 to 42). Cumulative incidences of acute and chronic GVHD were 21% and 44%, respectively. The 2-year PFS was 50% (95% CI, 32 to 65) and OS was 56% (95% CI, 38 to 71). For patients with AML in first complete remission, 2-year PFS and OS were both 82% (95% CI, 55 to 94). RIC with busulfan and clofarabine leads to successful engraftment with acceptable rates of NRM and GVHD. PMID:26260679

    The effects of imatinib plus chemotherapy were assessed in 87 patients with newly diagnosed Philadelphia chromosome-positive (Ph(+) ) acute lymphoblastic leukemia (ALL). Imatinib was administered continuously, starting from the eighth day of remission induction chemotherapy, then through five courses of consolidation or until allogeneic hematopoietic cell transplantation (HCT). Patients who were not transplanted were maintained on imatinib for 2 years. Eighty-two patients (94.3%) achieved complete remission (CR). Among these 82 CR patients, 40 experienced recurrence of leukemia. The 5-year relapse free survival (RFS) rate and overall survival (OS) rates were 39.0% and 33.4%, respectively. In total, 56 patients underwent allogeneic HCT in first CR. The 5-year cumulative incidence of relapse and OS rate of them were 59.1% and 52.6%, respectively. Six of seven patients who were maintained on imatinib after completion of consolidation relapsed and the median time of RFS was 40.7 months. In total patient, cumulative molecular CR rate was 88.5% and median time of molecular CR duration was 13 months. Initial imatinib dose intensity was significantly associated with median CR duration (P < 0.0001), and overall survival (P = 0.002). During the initial phase of treatment of patients with Ph(+) ALL, it is important to maintain imatinib dose intensity. PMID:26228525

    Natural killer (NK) cells mediate GVL effects after allogeneic hematopoietic cell transplantation (allo-HCT) by the production of inflammatory cytokines and by direct target lysis. The acquisition of both functions was presumed to be developmentally linked, but this linkage remained unstudied after allo-HCT. We tested the cytokine production and degranulation of reconstituting NK cells after adult unrelated donor or umbilical cord blood grafting. Recipients of T cell-depleted transplants, receiving no immune suppression, showed diminished NK cell degranulation. In contrast, degranulation was normal or increased after T-cell replete transplants given with immune suppression. Strikingly, target cell-induced IFNγ production was markedly diminished in all transplant settings, especially with T cell-depleted or naive T cell-containing umbilical cord blood grafts, suggesting a role for T cells in NK education. Although degranulation was similar in the KIR(+) and KIR(-) populations that coexpressed NKG2A, target cell-induced IFNγ production was limited to the subset of NK cells expressing KIR inhibited by self-ligands. Thus, cytokine production and cytotoxic function do not consistently coexist in NK cells reconstituting after allo-HCT. Exposure to IL-15 rapidly increased target-inducible IFNγ production, indicative of IL-15's potential as a therapeutic tool to enhance NK cell function to protect against infection and relapse after allo-HCT.

    Infectious complications after allogeneic haematopoietic stem cell transplantation (allo-HCT) remain a clinical challenge. This is a guideline provided by the AGIHO (Infectious Diseases Working Group) of the DGHO (German Society for Hematology and Medical Oncology). A core group of experts prepared a preliminary guideline, which was discussed, reviewed, and approved by the entire working group. The guideline provides clinical recommendations for the preventive management including prophylactic treatment of viral, bacterial, parasitic, and fungal diseases. The guideline focuses on antimicrobial agents but includes recommendations on the use of vaccinations. This is the updated version of the AGHIO guideline in the field of allogeneic haematopoietic stem cell transplantation utilizing methods according to evidence-based medicine criteria. PMID:27339055

    Purpose Acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS) primarily afflict older individuals. Hematopoietic cell transplantation (HCT) is generally not offered because of concerns of excess morbidity and mortality. Reduced-intensity conditioning (RIC) regimens allow increased use of allogeneic HCT for older patients. To define prognostic factors impacting long-term outcomes of RIC regimens in patients older than age 40 years with AML in first complete remission or MDS and to determine the impact of age, we analyzed data from the Center for International Blood and Marrow Transplant Research (CIBMTR). Patients and Methods We reviewed data reported to the CIBMTR (1995 to 2005) on 1,080 patients undergoing RIC HCT. Outcomes analyzed included neutrophil recovery, incidence of acute or chronic graft-versus-host disease (GVHD), nonrelapse mortality (NRM), relapse, disease-free survival (DFS), and overall survival (OS). Results Univariate analyses demonstrated no age group differences in NRM, grade 2 to 4 acute GVHD, chronic GVHD, or relapse. Patients age 40 to 54, 55 to 59, 60 to 64, and ≥ 65 years had 2-year survival rates as follows: 44% (95% CI, 37% to 52%), 50% (95% CI, 41% to 59%), 34% (95% CI, 25% to 43%), and 36% (95% CI, 24% to 49%), respectively, for patients with AML (P = .06); and 42% (95% CI, 35% to 49%), 35% (95% CI, 27% to 43%), 45% (95% CI, 36% to 54%), and 38% (95% CI, 25% to 51%), respectively, for patients with MDS (P = .37). Multivariate analysis revealed no significant impact of age on NRM, relapse, DFS, or OS (all P > .3). Greater HLA disparity adversely affected 2-year NRM, DFS, and OS. Unfavorable cytogenetics adversely impacted relapse, DFS, and OS. Better pre-HCT performance status predicted improved 2-year OS. Conclusion With these similar outcomes observed in older patients, we conclude that older age alone should not be considered a contraindication to HCT. PMID:20212255

    Intensive chemotherapy followed by allogeneic stem cell transplantation (alloSCT) can cure AML. Most studies on alloSCT in elderly AML report results of highly selected patient cohorts. Hardly any data exist on the effectiveness of prospective strategies intended to bring as many patients as possible to transplant. Between 2006 and 2011 we implemented a treatment algorithm for all newly diagnosed AML patients aged 61-75 years, consisting of intensive chemotherapy cycles to induce complete remission, followed by alloSCT. 44 of 60 (73%) newly diagnosed elderly AML patients started with chemotherapy. By meticulously following our algorithm in almost all patients, we could induce complete remission (CR) in 66% of patients starting with chemotherapy, and transplant 32% of these patients in continuous CR. Main reasons for failure were early relapse (16%), early death (14%), primary refractory disease (9%), and patient or physician decision to stop treatment (16%). Patients in continuous CR after first induction benefit most with 36% long-term survival. Patients not in CR after first induction benefit less; although additional chemotherapy induces CR in 45% of these patients, only 23% are transplanted and no long-term survival is observed, mainly due to relapse. Long-term survival in the group of 44 patients is 9% (median 4.5 years after alloSCT). Considering that 27% of patients do not start with chemotherapy and 64% of patients starting with chemotherapy do not reach alloSCT, the reasons for failure presented here should be used as a guide to develop new treatment algorithms to improve long-term survival in elderly AML patients.

    Graft-versus-host-disease (GVHD) is a major obstacle to successful allogeneic hematopoietic cell transplantation (alloHCT). Cannabidiol (CBD), a nonpsychotropic ingredient of Cannabis sativa, possesses potent anti-inflammatory and immunosuppressive properties. We hypothesized that CBD may decrease GVHD incidence and severity after alloHCT. We conducted a phase II study. GVHD prophylaxis consisted of cyclosporine and a short course of methotrexate. Patients transplanted from an unrelated donor were given low-dose anti-T cell globulin. CBD 300 mg/day was given orally starting 7 days before transplantation until day 30. Forty-eight consecutive adult patients undergoing alloHCT were enrolled. Thirty-eight patients (79%) had acute leukemia or myelodysplastic syndrome and 35 patients (73%) were given myeloablative conditioning. The donor was either an HLA-identical sibling (n = 28), a 10/10 matched unrelated donor (n = 16), or a 1-antigen-mismatched unrelated donor (n = 4). The median follow-up was 16 months (range, 7 to 23). No grades 3 to 4 toxicities were attributed to CBD. None of the patients developed acute GVHD while consuming CBD. In an intention-to-treat analysis, we found that the cumulative incidence rates of grades II to IV and grades III to IV acute GVHD by day 100 were 12.1% and 5%, respectively. Compared with 101 historical control subjects given standard GVHD prophylaxis, the hazard ratio of developing grades II to IV acute GVHD among subjects treated with CBD plus standard GVHD prophylaxis was .3 (P = .0002). Rates of nonrelapse mortality at 100 days and at 1 year after transplantation were 8.6% and 13.4%, respectively. Among patients surviving more than 100 days, the cumulative incidences of moderate-to-severe chronic GVHD at 12 and 18 months were 20% and 33%, respectively. The combination of CBD with standard GVHD prophylaxis is a safe and promising strategy to reduce the incidence of acute GVHD. A randomized double-blind controlled study is warranted

    Infections of the central nervous system (CNS) are infrequently diagnosed in immunocompetent patients, but they do occur in a significant proportion of patients with hematological disorders. In particular, patients undergoing allogeneic hematopoietic stem-cell transplantation carry a high risk for CNS infections of up to 15%. Fungi and Toxoplasma gondii are the predominant causative agents. The diagnosis of CNS infections is based on neuroimaging, cerebrospinal fluid examination and biopsy of suspicious lesions in selected patients. However, identification of CNS infections in immunocompromised patients could represent a major challenge since metabolic disturbances, side-effects of antineoplastic or immunosuppressive drugs and CNS involvement of the underlying hematological disorder may mimic symptoms of a CNS infection. The prognosis of CNS infections is generally poor in these patients, albeit the introduction of novel substances (e.g. voriconazole) has improved the outcome in distinct patient subgroups. This guideline has been developed by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO) with the contribution of a panel of 14 experts certified in internal medicine, hematology/oncology, infectious diseases, intensive care, neurology and neuroradiology. Grades of recommendation and levels of evidence were categorized by using novel criteria, as recently published by the European Society of Clinical Microbiology and Infectious Diseases.

    If regular artificial tears are ineffective for treatment of ocular surface disorders (including extreme dry eye syndrome), serum eye drops (SEDs) may provide a way to relieve the symptoms. However, not all patients are eligible to donate blood to produce autologous SEDs. Therefore, the use of allogeneic SEDs (obtained from voluntary blood donors) should be explored as an alternative for autologous SEDs. The Dutch blood bank organization is currently looking into the possibilities to provide allogeneic SEDs, as (GMP) regulations become stricter, making it for hospitals more difficult to provide autologous SEDs. To demonstrate effectiveness of both autologous and allogeneic SEDs, a clinical trial is planned. The current status of SEDs in The Netherlands is described. This paper is based on summary of the presentation given at the DGTI meeting in Dresden. PMID:26138910

    Single nucleotide polymorphisms (SNPs) in genes involved in the activation or regulation of innate and adaptive immune responses may modulate the susceptibility to and the natural history of certain chronic viral infections. The current study aimed to investigate whether donor and recipient SNPs in the chemokine receptor 5 (rs1800023), monocyte chemoattractant protein 1 (rs13900), interleukin-10 (rs1878672), and Toll-like receptor 9 (rs352140) genes would exert any influence on the rate of incidence and features of CMV DNAemia in the allogeneic stem cell transplantation setting. This was a retrospective observational multicenter study. The cohort consisted of 102 non-consecutive allogeneic stem cell transplant recipients. SNP genotyping was performed by allele-specific real-time PCR. CMV surveillance was performed by the pp65 antigenemia assay/and or by real-time PCR. Seventy-three patients developed CMV DNAemia within the first 100 days after transplantation (71.5%). Neither donor nor recipient SNPs were associated significantly with the rate of incidence of active CMV infection, nor with the need for pre-emptive antiviral therapy. Both the duration of CMV DNAemia and the plasma CMV DNA peak load during episodes were significantly higher in patients harboring the donor (but not the recipient) chemokine receptor 5 A/A genotype, than in their A/G and G/G counterparts (P = 0.022 and P = 0.045, respectively). The data reported suggest that SNPs in chemokine receptor 5 may influence the dynamics of CMV infection in the Allo-SCT setting. PMID:25132583

    Non-Hodgkin lymphoma (NHL) disproportionately affects older patients, who do not often undergo allogeneic hematopoietic cell transplantation (HCT). We analyzed Center for International Blood and Marrow Transplant Research data on 1248 patients age ≥40 years receiving reduced-intensity conditioning (RIC) or nonmyeloablative (NMA) conditioning HCT for aggressive (n = 668) or indolent (n = 580) NHL. Aggressive lymphoma was more frequent in the oldest cohort 49% for age 40 to 54 versus 57% for age 55 to 64 versus 67% for age ≥65; P = .0008). Fewer patients aged ≥65 had previous autografting (26% versus 24% versus 9%; P = .002). Rates of relapse, acute and chronic GVHD, and nonrelapse mortality (NRM) at 1 year post-HCT were similar in the 3 age cohorts (22% [95% confidence interval (CI), 19% to 26%] for age 40 to 54, 27% [95% CI, 23% to 31%] for age 55 to 64, and 34% [95% CI, 24% to 44%] for age ≥65. Progression-free survival (PFS) and overall survival (OS) at 3 years was slightly lower in the older cohorts (OS: 54% [95% CI, 50% to 58%] for age 40 to 54; 40% [95% CI, 36% to 44%] for age 55 to 64, and 39% [95% CI, 28% to 50%] for age ≥65; P < .0001). Multivariate analysis revealed no significant effect of age on the incidence of acute or chronic GVHD or relapse. Age ≥55 years, Karnofsky Performance Status <80, and HLA mismatch adversely affected NRM, PFS, and OS. Disease status at HCT, but not histological subtype, was associated with worse NRM, relapse, PFS, and OS. Even for patients age ≥55 years, OS still approached 40% at 3 years, suggesting that HCT affects long-term remission and remains underused in qualified older patients with NHL. PMID:24641829

    Pretransplant values of serum ferritin, albumin, and peripheral blood counts were previously suggested to provide prognostic information about hematopoietic cell transplantation (HCT) outcomes. Whether these "biomarkers" have prognostic value independent of each other and the HCT-comorbidity index (HCT-CI) is unknown. We analyzed data from 3917 allogeneic HCT recipients at multiple sites in the United States and Italy using multivariate models including each biomarker and the HCT-CI. Data from all sites were then randomly divided into a training set (n = 2352) to develop weights for the relevant biomarkers to be added to the HCT-CI scores and a validation set (n = 1407) to validate an augmented HCT-CI compared with the original index. Multivariate analysis with data from one site showed that ferritin, albumin, and platelets-not neutrophils or hemoglobin-were independently associated with increased nonrelapse mortality (NRM) and decreased overall survival. Findings were validated in data from the other sites. Subsequently, in a training set from all sites, ferritin >2500 mg/dL (hazard ratio [HR], 1.69); albumin 3 to 3.5 g/dL (HR, 1.61) and <3.0 g/dL (HR, 2.27); and platelets 50 to <100,000 (HR, 1.28), 20 to <50,000 (HR, 1.29), and <20,000 (HR, 1.55) were statistically significantly associated with NRM. Weights were assigned to these laboratory values following the same equation used to design the original index. In the validation set, the addition of the biomarkers to the original index to develop an augmented HCT-CI resulted in a statistically significant increase in a higher c-statistic estimate for prediction of NRM (P = .0007). Ferritin, albumin, and platelet counts are important prognostic markers that further refine the discriminative power of the HCT-CI for transplant outcomes. PMID:25862589

    Between 1982 and 2000, 172 patients with acute myelogenous leukaemia (AML) received haematopoietic stem cell transplants (SCT) from related (n = 132) or unrelated (n = 40) donors at four Austrian transplant centres and their results were reported to the Austrian Stem Cell Transplantation Registry. Conditioning for SCT consisted of cyclophosphamide and total body irradiation in 156 (91%) patients. Graft-versus-host disease (GVHD) prophylaxis was with standard cyclosporine and methotrexate in 95 (55%) patients. Median post-transplant follow-up was 5.6 years (range, 0.2--16.7). Multivariate analysis of transplant-related mortality (TRM) identified four variables associated with a lower risk: disease status of first complete remission (CR) at SCT, patient age of 45 years and younger, transplant performed during or after 1995, and lack of acute GVHD. Variables associated with significantly improved leukaemia-free survival were: bone marrow as the stem cell source, disease status of first CR at SCT, and occurrence of chronic GVHD. In multivariate analysis, transplantation performed during or after 1995, first CR at SCT, occurrence of limited chronic GVHD and lack of acute GVHD grades III to IV were associated with increased overall survival. Based on these analyses, options for the improvement of results obtained with allogeneic SCT in patients with AML could be defined. PMID:12060131

    We conducted a study to estimate the maximum tolerated dose (MTD) of I-131-anti-CD45 antibody (Ab; BC8) that can be combined with a standard reduced-intensity conditioning regimen before allogeneic hematopoietic cell transplantation. Fifty-eight patients older than 50 years with advanced acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS) were treated with (131)I-BC8 Ab and fludarabine plus 2 Gy total body irradiation. Eighty-six percent of patients had AML or MDS with greater than 5% marrow blasts at the time of transplantation. Treatment produced a complete remission in all patients, and all had 100% donor-derived CD3(+) and CD33(+) cells in the blood by day 28 after the transplantation. The MTD of I-131-BC8 Ab delivered to liver was estimated to be 24 Gy. Seven patients (12%) died of nonrelapse causes by day 100. The estimated probability of recurrent malignancy at 1 year is 40%, and the 1-year survival estimate is 41%. These results show that CD45-targeted radiotherapy can be safely combined with a reduced-intensity conditioning regimen to yield encouraging overall survival for older, high-risk patients with AML or MDS.

    To better understand predictive factors and improve the clinical outcome of allogeneic transplant for patients with Philadelphia positive acute lymphoblastic leukemia, we analyzed 67 Southeast Asian patients transplanted in our institutions. Multivariate analysis showed that disease status before transplant, year of transplant and, interestingly, French-American-British (FAB) subtype had a significant impact on overall survival (OS) and non-relapse mortality. Patients who were minimal residual disease (MRD) negative at transplant had a 3-year OS of 73% compared to those who were MRD positive (45%) and refractory (0%). The 3-year cumulative incidence of relapse was 18% and 36% for the MRD negative and positive groups, respectively. FAB L1 subtype had a significantly superior 3-year OS of 63% vs. 29% for L2 subtype. Pre-transplant use of a tyrosine kinase inhibitor significantly improved outcomes in univariate but not multivariate analysis, as it served to induce more patients into MRD negativity, which was the factor that directly improved transplant outcome.

    A novel approach to personalizing postgrafting immunosuppression in hematopoietic cell transplant (HCT) recipients is evaluating inosine monophosphate dehydrogenase (IMPDH) activity as a drug-specific biomarker of mycophenolic acid (MPA)-induced immunosuppression. This prospective study evaluated total MPA, unbound MPA, and total MPA glucuronide plasma concentrations and IMPDH activity in peripheral blood mononuclear cells (PMNC) at five time points after the morning dose of oral mycophenolate mofetil (MMF) on day +21 in 56 nonmyeloablative HCT recipients. Substantial interpatient variability in the pharmacokinetics and pharmacodynamics was observed and accurately characterized by the population pharmacokinetic/dynamic model. IMPDH activity decreased with increasing MPA plasma concentration, with maximum inhibition coinciding with maximum MPA concentration in most patients. The overall relationship between MPA concentration and IMPDH activity was described by a direct inhibitory Emax model with an IC50 = 3.23 mg/L total MPA and 57.3 ng/mL unbound MPA. The day +21 IMPDH area under the effect curve (AUEC) was associated with cytomegalovirus reactivation, non-relapse mortality, and overall mortality. In conclusion, a pharmacokinetic/dynamic model was developed that relates plasma MPA concentrations with PMNC IMPDH activity after an MMF dose in HCT recipients. Future studies should validate this model and confirm that day +21 IMPDH AUEC is a predictive biomarker. PMID:24727337

    Myeloid sarcoma of the breast is a rare manifestation of acute myeloid leukaemia (AML). This report describes a patient who was diagnosed with AML FAB M2. Molecular analysis showed evidence of an NPM1 mutation (subtype A) and internal tandem duplications of the FLT3 gene (FLT3-ITD). Eight months after allogeneic stem cell transplantation, the patient developed a palpable mass in the left breast initially suspected as breast carcinoma. Core needle biopsy of the lesion resulted in diagnosis of myeloid sarcoma. Molecular analysis of formalin-fixed specimens of the breast tumour confirmed the known FLT3 and NPM1 gene mutations. Immunohistochemically, an aberrant cytoplasmic staining pattern for NPM1 and overexpression of FLT3 were demonstrated. The myeloid sarcoma showed complete transient resolution following treatment with the kinase inhibitor sorafenib. However, the patient developed bone marrow relapse and died in fatal cerebral haemorrhage 1 year after initial diagnosis of AML. In summary, combined molecular and immunohistochemical examination of NPM1 and FLT3 is helpful in the diagnosis of extramedullary manifestations of AML in core needle biopsies. PMID:20360144

    Central nervous system (CNS) involvement is a severe complication of BCR-ABL-positive leukemia after allogenic stem cell transplantation (alloSCT) associated with fatal outcome. Although second-generation tyrosine-kinase inhibitors (TKI) such as nilotinib have shown activity in systemic BCR-ABL+ disease, little data exists on their penetration and efficacy within the CNS. Four patients (3 male, 1 female; age 15–49) with meningeal relapse after alloSCT and subsequent treatment with nilotinib were identified. A total of 17 cerebrospinal fluid (csf) and serum samples were assessed for nilotinib concentration and patient outcome was recorded. Nilotinib concentrations showed a low median csf/plasma ratio of 0.53% (range 0.23–1.5%), yet pronounced clinical efficacy was observed with long-lasting responses (>1 year) in three patients. Comparison with historical data showed a trend towards superior efficacy of nilotinib versus imatinib. Despite poor csf penetration, nilotinib showed significant clinical activity in CNS relapse of BCR-ABL+ leukemias. As nilotinib has a high protein-binding affinity, the low-protein concentration in csf could translate into a relatively higher amount of free and therefore active nilotinib in csf as compared to blood, possibly explaining the observed efficacy. Thus, treatment with a 2nd generation TKI warrants further investigation and should be considered in cases of CNS relapse of BCR-ABL-positive leukemia after alloSCT. PMID:25025064

    Epidemiology and prognosis of complications related to allogeneic hematopoietic stem cell transplant (HSCT) recipients requiring admission to intensive care unit (ICU) have not been reassessed precisely in the past few years. We performed a retrospective single-center study on 318 consecutive HSCT patients (2009-2013), analyzing outcome and factors prognostic of ICU admission. Among these patients, 73 were admitted to the ICU. In all, 32 patients (40.3%) died in ICU, 46 at hospital discharge (63%) and 61 (83.6%) 1 year later. Survivors had a significantly lower sequential organ failure assessment (SOFA) score, serum lactate and bilirubin upon ICU admission. Catecholamine support, mechanical ventilation (MV) and/or renal replacement therapy during ICU stay, a delayed organ support and an active graft versus host disease (GvHD) significantly worsen the outcome. By multivariate analysis, the worsening of SOFA score from days 1 to 3, the need for MV and the occurrence of an active GvHD were predictive of mortality. In conclusion, the incidence of HSCT-related complications requiring an admission to an ICU was at 22%, with an ICU mortality rate of 44%, and 84% 1 year later. A degradation of SOFA score at day 3 of ICU, need of MV and occurrence of an active GvHD are main predictive factors of mortality. PMID:26569092

    Background Concerns regarding the safety of transfused blood have prompted reconsideration of the use of allogeneic (from an unrelated donor) red blood cell (RBC) transfusion, and a range of techniques to minimise transfusion requirements. Objectives To examine the evidence for the efficacy of cell salvage in reducing allogeneic blood transfusion and the evidence for any effect on clinical outcomes. Search methods We identified studies by searching CENTRAL (The Cochrane Library 2009, Issue 2), MEDLINE (1950 to June 2009), EMBASE (1980 to June 2009), the internet (to August 2009) and bibliographies of published articles. Selection criteria Randomised controlled trials with a concurrent control group in which adult patients, scheduled for non-urgent surgery, were randomised to cell salvage (autotransfusion) or to a control group who did not receive the intervention. Data collection and analysis Data were independently extracted and the risk of bias assessed. Relative risks (RR) and weighted mean differences (WMD) with 95% confidence intervals (CIs) were calculated. Data were pooled using a random-effects model. The primary outcomes were the number of patients exposed to allogeneic red cell transfusion and the amount of blood transfused. Other clinical outcomes are detailed in the review. Main results A total of 75 trials were included. Overall, the use of cell salvage reduced the rate of exposure to allogeneic RBC transfusion by a relative 38% (RR 0.62; 95% CI 0.55 to 0.70). The absolute reduction in risk (ARR) of receiving an allogeneic RBC transfusion was 21% (95% CI 15% to 26%). In orthopaedic procedures the RR of exposure to RBC transfusion was 0.46 (95% CI 0.37 to 0.57) compared to 0.77 (95% CI 0.69 to 0.86) for cardiac procedures. The use of cell salvage resulted in an average saving of 0.68 units of allogeneic RBC per patient (WMD −0.68; 95% CI −0.88 to −0.49). Cell salvage did not appear to impact adversely on clinical outcomes. Authors’ conclusions

    Stem cell (SC)-based therapies are a developing mean to repair, restore, maintain, or enhance organ functioning through life span. They are in particular a fast track to restore function in failing heart. Various types of SCs have been used in experimental and clinical studies showing the potential of these cells to revolutionize the treatment of heart diseases. Autologous cells have been privileged to overpass immunological barriers. The field has progressed tremendously and the hurdles, which have been largely overlooked in the excitement over the expected benefit the immunogenicity, have been revealed. Also, manufacturing of patient-specific clinical grade SC product, whether adult stem or reprogrammed induced pluripotent SCs, and the availability of these cells in sufficient amounts and status when needed is questionable. In contrast, adult SCs derived from healthy donors, thus allogeneic, have the advantage to be immediately available as an 'off-the-shelf' therapeutic product. The challenge is to overcome the immunological barriers to their transplantation. Recent research provided new insights into the mode of action and immune behavior of SCs in autologous as well as allogeneic settings. Lessons are learned and immune paradigms are changing: allogenicity, if balanced could be part of the dynamic and durable mechanisms that are critical to sustain cardiac regeneration and repair. We discuss the hurdles, lessons, and advances accomplished in the field through the progressive journey of cardiac-derived stem/progenitor cells toward allogeneic cardiac regenerative/reparative therapy.

    Cytoreduction before allogeneic stem cell transplantation (allo-SCT) for patients with myelodysplastic syndromes remains a debatable issue. After excluding patients who had received preconditioning induction chemotherapy, we analyzed 128 consecutive patients with myelodysplastic syndrome who received reduced-intensity or nonmyeloablative conditioning (RIC/NMA) allo-SCT. Among them, 40 received azacitidine (AZA) before transplant (AZA group) and 88 were transplanted up front (best supportive care [BSC] group). At diagnosis, 55 patients had intermediate 2 or high-risk scores per the International Prognostic Scoring System and 33 had a high cytogenetic risk score. Progression to a more advanced disease before allo-SCT was recorded in 22 patients. Source of stem cells were blood (n = 112) or marrow (n = 16) from sibling (n = 78) or HLA-matched unrelated (n = 50) donors. With a median follow-up of 60 months, 3-year overall survival, relapse-free survival, cumulative incidence of relapse, and nonrelapse mortality were, respectively, 53% versus 53% (P = .69), 37% versus 42% (P = .78), 35% versus 36% (P = .99), and 20% versus 23% (P = .74), for the AZA group and BSC group, respectively. Multivariate analysis confirmed the absence of statistical differences in outcome between the AZA and BSC groups, after adjusting for potential confounders using the propensity score approach. The absence of cytoreduction before RIC/NMA allo-SCT did not seem to alter the outcome. However, our results emphasize the need to perform prospective protocols to delineate the role of debulking strategy and to identify subsets of patients who may benefit from this approach.

    We evaluated the outcomes and associated prognostic factors in 233 patients undergoing allogeneic hematopoietic cell transplantation (HCT) for primary myelofibrosis (MF) using reduced intensity conditioning (RIC). Median age at HCT was 55 years. Donors were: matched sibling donor (MSD), 34%; HLA-well-matched unrelated donors (URD), 45%; and partially/mismatched URD, 21%. Risk stratification according to Dynamic International Prognostic Scoring System (DIPSS): low, 12%; intermediate-1, 49%; intermediate-2, 37%; and high, 1%. The probability of survival at 5-years was 47% (95% CI 40–53). In a multivariate analysis, donor type was the only independent factor associated with survival. Adjusted probabilities of survival at 5-years for MSD, well matched URD and partially matched/mismatched URD were 56% (95% CI 44–67), 48% (95% CI 37–58), and 34% (95% CI 21–47), respectively (p=0.002). Relative risks (RR) for NRM for well-matched URD and partially matched/mismatched URD were 3.92 (p=0.006) and 9.37 (p<0.0001), respectively. A trend towards increased NRM (RR 1.7, p=0.07) and inferior survival (RR 1.37, p=0.10) was observed in DIPSS-intermediate-2/high-risk patients compared to DIPSS-low/intermediate-1 risk patients. RIC HCT is a potentially curative option for patients with MF, and donor type is the most important factor influencing survival in these patients. PMID:24161923

    The prognosis after hematopoietic cell transplantation (HCT) for the treatment of leukemia or lymphoma in humans is influenced by donor-derived natural killer (NK) cells, which enhance the graft-versus-leukemia (GVL) effect. Such alloreactive killer cells can be generated in vivo after HCT if the donor expresses killer cell immunoglobulin-like receptors (KIRs), such as KIR2DL1, KIR2DL2/3, or KIR3DL1, for which the recipient lacks HLA class I ligands. We studied effector cells from 22 KIR/HLA-ligand mismatched and 14 KIR/HLA-ligand matched, primarily HLA-matched patient-donor pairs after allogeneic HCT. A novel 8-color flow cytometry panel allowed us to characterize effector-cell populations without "broadly reactive" inhibitory receptors such as CD94/NKG2A or LIR1. The numbers of such NKG2A(-) LIR1(-) NK cells increased following HCT in patients transplanted by KIR/HLA-ligand mismatched grafts, compared to KIR/HLA-ligand matched grafts, and in patients transplanted from donors of the A/B, compared to A/A, KIR haplotypes. NKG2A(-)LIR1(-) NK cells expressing only those inhibitory KIRs for which the patient had no HLA class I ligands could be stimulated by HLA class I-deficient cells to express CD107a. Thus, NKG2A(-)LIR1(-) NK cells may be important GVL effector cells following HCT, even in patients transplanted from HLA-matched donors. PMID:20044012

    Clinical research on allogeneic cultured dermal substitute (CDS), which was newly developed at the R&D Center for Artificial Skin of Kitasato University, has been carried out in medical centers across Japan with the support of the Millennium Project of the Ministry of Health, Labor and Welfare of Japan. Allogeneic CDS was prepared by cultivation of fibroblasts on a two-layered spongy matrix of hyaluronic acid and atelo-collagen. This paper reports the clinical results of application of allogeneic CDS in 12 patients with full-thickness skin defects after surgical resection of skin tumors. In 9 of 10 patients, healthy granulation tissue developed immediately, allowing us to perform split-thickness skin grafts at an early stage. In two cases, allogeneic CDS was used to cover an expanded mesh skin graft that had been applied to treat a large ulcer, and rapid epithelization was observed. No patient developed local infection nor local tumor recurrence after treatment with CDS. The spongy matrix itself as well as the vascular endothelial growth factor (VEGF) released by the allogeneic CDS seemed to be beneficial for the treatment of intractable skin ulcers. Allogeneic CDS functions as an excellent biological dressing, and could dramatically change the treatment of intractable skin ulcers. PMID:15246944

    Summary Prior therapy with rituximab might attenuate disparate histocompatibility antigen presentation by B cells, thus decreased the risk of acute graft-versus-host disease (GVHD) and improved survival. We tested this hypothesis by comparing the outcomes of 435 B-cell lymphoma patients who received allogeneic transplantation from 1999 to 2004 in the Center for International Blood and Marrow Transplant Research database: 179 subjects who received rituximab within 6 months prior to transplantation (RTX cohort) and 256 subjects who did not receive RTX within 6 months prior to transplantation (No-RTX cohort). The RTX cohort had a significantly lower incidence of treatment-related mortality (TRM) (relative risk [RR] = 0.68; 95% confidence interval [CI], 0.47 - 1.0; P = 0.05), lower acute grade II-IV (RR = 0.72; 95% CI, 0.53 - 0.97; P = 0.03) and III-IV GVHD (RR = 0.55; 95% CI, 0.34 - 0.91; P = 0.02). There was no difference in the risk of chronic GVHD, disease progression or relapse. Progression-free survival (PFS) (RR = 0.68; 95% CI 0.50 - 0.92; P = 0.01) and overall survival (OS) (RR = 0.63; 95% CI, 0.46 - 0.86; P = 0.004) were significantly better in the RTX cohort. Prior RTX therapy correlated with less acute GVHD, similar chronic GVHD, less TRM, better PFS and OS. PMID:19344418

    Minimal residual disease (MRD) of 30 adult AML patients was monitored by multiparameter flow cytometry (MFC) and WT1 expression before and after allogeneic stem cell transplantation (allo-SCT). Diagnostic performance of pre-transplant MRD measured by MFC was higher than that obtained by WT1 expression. Comparable results were displayed at day +30 post-transplant, while better values by WT1 compared to MFC were found at day +90. Positive MRD by MFC predicted a shorter disease free survival (DFS) before and 1 month after transplant (p=0.006 and p=0.005), while only high WT1 levels at 1 month from the transplant significantly impacted on DFS (p=0.010). Our results support the idea that MRD monitoring by MFC should be suggested before and 30 days after the transplant, while WT1 expression should be preferred after this procedure. The assessment of MRD at day +30 from allo-SCT is recommended as post transplant check-point for the predictive role displayed, independently of the method used. PMID:25498507

    Acute myeloid leukemia is a clonal neoplasm derived from myeloid progenitor cells with a varying outcome. The initial goal of treatment is the achievement of complete remission, defined for over 40 years by morphology. However, without additional post-remission treatment the majority of patients relapse. In many cases of acute myeloid leukemia, allogeneic stem cell transplantation offers the best prospects of cure. In 2013, 5608 stem cell transplantations in acute myeloid leukemia were performed in Europe (5228 allogeneic and 380 autologous stem cell transplantations). Most stem cell transplantations are performed in first complete remission. However, despite a considerable reduction in the chance of relapse, in most studies, overall survival benefit of allogeneic stem cell transplantation is modest due to substantial non-relapse mortality. Here we discuss the many factors related to the risk of relapse after allogeneic stem cell transplantation. PMID:26721801

    As part of a pharmacogenetic study, paired blood and oral fluid samples were tested for the IL28B polymorphism (rs12979860) before and after hematopoietic cell transplantation (HCT) to evaluate changes in the genotype and investigate the utility of genotyping in oral fluid in HCT recipients. In 54 patients with leukemia >18 years of age, samples were collected approximately 7 days before HCT and 60 days after HCT. IL28B polymorphism testing was performed using real-time PCR with allele-specific probes. Twenty-four patients had the same genotype as their donors. In 30 patients, the genotype was different from that of the donor. In the oral fluid samples, 4 retained the recipient's genotype, and 18 had a genotype that matched that of the donor. In the remaining 8 patients, the results could not be characterized and appeared to be a combination of both, suggesting mixed proportions of donor and recipient cells. The assumption was that the sloughed epithelial cells of the mouth are of recipient origin. However, oral fluid is a mixture that contains varying numbers of cells of the recipient and immunomodulatory cells from the donor. Therefore, the use of oral fluid after HCT for clinical pharmacogenetics purposes needs further investigation. PMID:27371869

    To evaluate the prognostic value of the expression of the mixed lineage leukemia (MLL) gene for predicting the relapse of patients with MLL-rearranged acute leukemia (AL) after allogeneic hematopoietic stem cell transplantation (allo-HSCT), the levels of MLL transcripts in bone marrow (BM) specimens were monitored serially by real-time quantitative polymerase chain reaction (RQ-PCR) at predetermined time points in 40 patients with MLL-rearranged AL who were treated with allo-HSCT. These patients were followed for a median of 24.5 months (range, 8 to 60 months). A total of 236 BM samples were collected and analyzed. Of these, 230 were monitored concurrently for minimal residual disease (MRD) by flow cytometry (FCM) for leukemia-associated aberrant immune phenotypes and by RQ-PCR for the expression of the Wilms tumor (WT1) gene. The 3-year cumulative incidence of relapse in patients who experienced MLL-positive patients (MLL > .0000%) (n = 9) after HSCT was 93.5% (95% confidence interval [CI], 87% to 100%) compared with 12.5% (95% CI, 5.6% to 19.4%) for MLL-negative patients (n = 31) (P < .001). For these 2 patient groups, the 3-year overall survival (OS) was 12.5% (95% CI, .8% to 24.2%) and 77.8% (95% CI, 68.4% to 87.2%) (P < .001), respectively, and the 3-year leukemia-free survival (LFS) was 0% and 72.2% (95% CI, 61.1% to 83.3%), respectively (P < .001). MLL positivity was associated with a higher rate of relapse (hazard ratio [HR], 18.643; 95% CI, 3.449 to 57.025; P = .001), lower LFS (HR, 7.267; 95% CI, 2.038 to 25.916; P = .002), and lower OS (HR, 8.259; 95% CI, 2.109 to 32.336; P = .002), as determined by Cox multivariate analysis. The expression of the MLL gene had a higher specificity and sensitivity than WT1 or MRD monitored by FCM for predicting the relapse of the patients with MLL + AL. Our results suggest that monitoring the expression of the MLL gene may help to identify patients with MLL + AL who are at high risk of relapse after allo-HSCT and may

    The benefit of survival at the expense of new GVHD after DLI for acute leukemia following human allogeneic hematopoietic cell transplantation (allo-HCT) remains a matter of controversy. The detection of biological markers predicting this outcome would be an enormous breakthrough. The purpose of this study was the analysis of CT60 single-nucleotide polymorphism (SNP) of the CTLA-4 T-regulatory gene as a surrogate marker for DLI outcome in this difficult setting. Using Pyrosequencing, we genotyped the alleles of the CT60 SNP of 79 DLI donors and correlated them with the post-DLI outcome of their matching recipients. The presence of a donor 'AA' or 'AG' CT60 genotype vs a 'GG' genotype was an independent factor for remaining in complete chimerism/remission post-DLI (odds ratio (OR) 2.61 vs 0.42, respectively, P=0.05). Further, in cases with evident post-DLI allo-reactivity the importance of an 'AA' or 'AG' vs a 'GG' genotype gained significance for ongoing complete chimerism (OR 4.35 vs 0.32, P=0.03). Neither alterations in cumulative DLI dose nor any other clinical parameter significantly weakened the importance of CT60 SNP. Our results provide evidence for the necessity of genotyping CT60 SNP prior to DLI administration in patients with acute leukemia. PMID:21552305

    Nitronaproxen [AZD 3582, HCT 3012, naproxen nitroxybutylester, NO-naproxen] is a naproxen derivative with similar anti-inflammatory activity to the parent compound, but with less gastrointestinal toxicity. It is the first of a new class of analgesic and anti-inflammatory drugs known as cyclo-oxygenase-inhibiting nitric oxide donators (CINODs), which are under development by NicOx. The better gastrointestinal tolerability of nitronaproxen appears to be due to its release of nitric oxide (NO) and the consequent maintenance of tissue perfusion and integrity. Nitronaproxen is in phase III clinical development for the treatment of osteoarthritis and is available for licensing. AstraZeneca had been a worldwide licensee for nitronaproxen and other CINODs. However, the results of phase II clinical trials of nitronaproxen did not fulfill AstraZeneca's strategic commercial criteria for further investment and NicOx reacquired rights following AstraZeneca's decision to discontinue its involvement in 2003. NicOx was surprised by AstraZeneca's decision, and remained fully convinced of the potential of nitronaproxen. NicOx is seeking new partners for development of compounds of the CINOD class. Nitronaproxen is in a phase III clinical trial for the treatment of osteoarthritis (OA) of the knee. The 13-week trial completed enrolment of 820 patients from 120 clinical sites in the US in May 2006. The study is designed to confirm that nitronaproxen is superior to placebo and is as effective as naproxen in relieving signs and symptoms of OA. The study will also seek to show that nitronaproxen has no adverse effect on blood pressure.

    Background Crohn's disease (CD) is associated with defective sensing of pathogens in genetically susceptible individuals. Nucleotide-binding oligomerization domain containing 2 (NOD2) mutations in coding regions are strongly linked to CD pathogenesis. Our laboratory has reported that microRNAs (miRNAs) are differentially expressed in CD. However, miRNA regulation of NOD2 remains unknown. This study was designed to determine whether miRNAs regulate NOD2 expression as well as downstream nuclear factor kappaB activation and inflammatory responses in colonic epithelial HCT116 cells. Methods NOD2 and miRNA expression in stimulated HCT116 cells were assessed by quantitative reverse transcription–polymerase chain reaction. Regulation of NOD2 expression by miRNAs was determined by luciferase reporter construct assays and transfection of specific miRNA mimics. Regulation of NOD2 signaling and immune response by miRNAs was assessed by transfection of mimics followed by muramyl dipeptide stimulation. Results Muramyl dipeptide-induced increases in NOD2, interleukin-8, and CXCL3 expression were inversely associated with miRNA expression. Overexpression of miR-192, miR-495, miR-512, and miR-671 suppressed NOD2 expression, muramyl dipeptide-mediated NF-κB activation, and messenger RNA expressions of interleukin-8 and CXCL3 in HCT116 cells. A single-nucleotide polymorphism (rs3135500) located in the NOD2 3′-untranslated region significantly reduced miR-192 effects on NOD2 gene expression. Conclusions To our knowledge, this is the first report demonstrating that miRNAs regulate NOD2 and its signaling pathway. Four miRNAs downregulate NOD2 expression, suppress NF-κB activity, and inhibit interleukin-8 and CXCL3 messenger RNA expression. Treatment of CD with miRNAs may represent a potential anti-inflammatory therapeutic strategy in CD patients with and without NOD2 gene mutations. PMID:24297055

    The intensity of conditioning regimen is highly correlated with outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT). We have previously reported that idarubicin (IDA) intensified BUCY2 regimen could reduce relapse and improve survival for high-risk hematological malignancies undergoing allo-HSCT. However, there is no published study comparing the efficacy of IDA-BUCY2 regimen for high-risk acute myeloid leukemia (AML) versus acute lymphocytic leukemia (ALL). We further retrospectively compared therapeutic outcomes of intensified conditioning regimen on 140 high-risk AML and ALL patients in the data analyses. IDA 15mg/m(2)/d was administered by continuous infusion from day -11 to -9, followed by intravenous injection of busulfan (BU) (3.2mg/kg/d) from day -6 to -4, and intravenous injection of cyclophosphamide (CY) (1.8g/m(2)/d) from day -3 to -2 in IDA-BUCY2 regimen. For high-risk AML, cumulative probabilities of 3-year relapse rates in IDA-BUCY2 and traditional BUCY2 regimens were 16.9%, 43.3% (P=0.016). Cumulative probabilities of 3-year overall survival (OS) and disease-free survival (DFS) were 69.2% vs 44.0% (P=0.024), and 66.9% vs 38.2% (P=0.01). However, two regimens showed no significant differences for high-risk ALL. Multivariate analysis also indicated that IDA intensified BUCY2 conditioning was the favorable variable to reduce relapse and elevate survival for high-risk AML patients. In conclusion, IDA-BUCY2 regimen reduces relapse and improves survival for high-risk AML undergoing allo-HSCT, but not presenting uniform therapeutic effects for high-risk ALL. PMID:27131062

    Purpose: Hematopoietic stem cell transplantation (HSCT) is the mainstay of treatment for adults with acute leukemia. Total body irradiation (TBI) remains an important part of the conditioning regimen for HCST. For those patients unable to tolerate myeloablative TBI (mTBI), reduced intensity TBI (riTBI) is commonly used. In this study we compared outcomes of patients undergoing mTBI with those of patients undergoing riTBI in our institution. Methods and Materials: We performed a retrospective review of all patients with acute leukemia who underwent TBI-based conditioning, using a prospectively acquired database of HSCT patients treated at our institution. Patient data including details of the transplantation procedure, disease status, Karnofsky performance status (KPS), response rates, toxicity, survival time, and time to progression were extracted. Patient outcomes for various radiation therapy regimens were examined. Descriptive statistical analysis was performed. Results: Between June 1985 and July 2012, 226 patients with acute leukemia underwent TBI as conditioning for HSCT. Of those patients, 180 had full radiation therapy data available; 83 had acute lymphoblastic leukemia and 94 had acute myelogenous leukemia; 45 patients received riTBI, and 135 received mTBI. Median overall survival (OS) was 13.7 months. Median relapse-free survival (RFS) for all patients was 10.2 months. Controlling for age, sex, KPS, disease status, and diagnosis, there were no significant differences in OS or RFS between patients who underwent riTBI and those who underwent mTBI (P=.402, P=.499, respectively). Median length of hospital stay was shorter for patients who received riTBI than for those who received mTBI (16 days vs 23 days, respectively; P<.001), and intensive care unit admissions were less frequent following riTBI than mTBI (2.22% vs 12.69%, respectively, P=.043). Nonrelapse survival rates were also similar (P=.186). Conclusions: No differences in OS or RFS were seen between

    In an attempt to improve outcomes for patients with acute myeloid leukemia (AML) after allogeneic hematopoietic cell transplantation (HCT), we conducted a Phase I/II study in which targeted irradiation delivered by 131I-anti-CD45 antibody was combined with targeted busulfan (BU; area-under-curve, 600-900 ng/ml) and cyclophosphamide (CY; 120 mg/kg). Fifty-two of 59 patients (88%) receiving a trace 131I-labeled dose of 0.5 mg/kg anti-CD45 murine antibody had higher estimated absorbed radiation in bone marrow and spleen than in any other organ. Forty-six patients were treated with 102-298 mCi 131I delivering an estimated 5.3-19 (mean 11.3) Gy to marrow, 17-72 (mean 29.7) Gy to spleen, and 3.5 Gy (n=4) to 5.25 Gy (n=42) to the liver. The estimated 3-year non-relapse mortality and disease-free survival (DFS) were 21% and 61%, respectively. These results were compared to those from 509 similar International Bone Marrow Transplant Registry patients transplanted using BU/CY alone. After adjusting for differences in age and cytogenetics-risk, the hazard of mortality among all antibody-treated patients was 0.65 times that of the Registry patients (95% CI 0.39-1.08; p=.09). The addition of targeted hematopoietic irradiation to conventional BU/CY is feasible and well tolerated, and Phase II results are sufficiently encouraging to warrant further study.

    Background: The large-scale utilization of allogenic blood transfusion and its associated outcomes have been described in critically ill patients and those undergoing high-risk cardiac surgery but not in patients undergoing elective total hip arthroplasty. The objective of this study was to determine the trends in utilization and outcomes of allogenic blood transfusion in patients undergoing primary total hip arthroplasty in the United States from 2000 to 2009. Methods: An observational cohort of 2,087,423 patients who underwent primary total hip arthroplasty from 2000 to 2009 was identified in the Nationwide Inpatient Sample. International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes 99.03 and 99.04 were used to identify patients who received allogenic blood products during their hospital stay. Risk factors for allogenic transfusions were identified with use of multivariable logistic regression models. We used propensity score matching to estimate the adjusted association between transfusion and surgical outcomes. Results: The rate of allogenic blood transfusion increased from 11.8% in 2000 to 19.0% in 2009. Patient-related risk factors for receiving an allogenic blood transfusion include an older age, female sex, black race, and Medicaid insurance. Hospital-related risk factors include rural location, smaller size, and non-academic status. After adjusting for confounders, allogenic blood transfusion was associated with a longer hospital stay (0.58 ± 0.02 day; p < 0.001), increased costs ($1731 ± $49 [in 2009 U.S. dollars]; p < 0.001), increased rate of discharge to an inpatient facility (odds ratio, 1.28; 95% confidence interval, 1.26 to 1.31), and worse surgical and medical outcomes. In-hospital mortality was not affected by allogenic blood transfusion (odds ratio, 0.97; 95% confidence interval, 0.77 to 1.21). Conclusions: The increase in allogenic blood transfusion among total hip arthroplasty patients is concerning

    Blood transfusion is usually meant to lower morbidity and mortality rates. Allogenous blood transfusion implies certain risks that can be avoided by autologous blood transfusions techniques including: preoperatory autologous blood donation, acute normovolemic hemodilution, intraoperatory and postoperatory blood salvage. Preoperatory blood donation and acute normovolemic hemodilution are used for planned interventions with an estimated blood loss higher than 20% of blood volume. These methods imply Erythropoietin and iron treatment. Intraoperatory and postoperatory blood salvage is performed by personnel trained in blood donation, handling and storage. Autologous blood transfusions are used for certain surgical procedures that commonly require transfusions: orthopedic surgery, radical prostatectomy, cardiovascular surgery, organ transplantation. An alternative to allogenous blood transfusion is the use of artificial oxygen transporters: human or animal hemoglobin solutions or pefluorocarbonate solutions. These solutions do not require cross reactions, do not carry diseases and are generally well tolerated and easily stored in the operating room, ambulance and other transport means. They have however a slight degree of toxicity. PMID:21495338

    The purpose of this investigation was to define the maximum tolerated dose (MTD) of unshielded total body irradiation (TBI) delivered from dual {sup 60}C sources at an exposure rate of 0.08 Gy/min and given in thrice daily fractions of 1.2 Gy in patients with advanced lymphoid malignancies. Forty-four patients with a median age of 28 (range 6-48) years were entered into a Phase I/II study. All patients received cyclophosphamide (Cy), 120 mg/kg administered over 2 days before TBI. Marrow from human leukocyte antigen (HLA) identical siblings was infused following the last dose of TBI. An escalation-deescalation schema designed to not exceed an incidence of 25% of Grade 3-4 regimen-related toxicities (RRTs) was used. The first dose level tested was 13.2 Gy followed by 14.4 Gy. None of the four patients at the dose level of 13.2 Gy developed Grade 3-4 RRT. Two of the first eight patients receiving 14.4 Gy developed Grade 3-4 RRT, establishing this as the MTD. An additional 32 patients were evaluated at the 14.4 Gy level to confirm these initial observations. Of 40 patients receiving 14.4 Gy, 13 (32.5%) developed Grade 3-4 RRTs; 46% in adults and 12% in children. The primary dose limiting toxicity was Grade 3-4 hepatic toxicity, which occurred in 12.5% of patients. Noninfectious Grade 3-4 interstitial pneumonia syndrome occurred in 5% of patients. The actuarial probabilities of event-free survival, relapse, and nonrelapse mortality at 2 years were 0.10, 0.81, and 0.47, respectively, for patients who received 14.4 Gy of TBI. The outcome for patients receiving 14.4 Gy of TBI was not different from previous studies of other CY and TBI regimens in patients with advanced lymphoid malignancies. These data showed that the incidence of Grade 3-4 RRTs in adults was greater than the 25% maximum set as the goal of this study, suggesting that 13.2 Gy is a more appropriate dose of TBI for adults, while 14.4 Gy is an appropriate dose for children. 36 refs., 1 fig., 3 tabs.

    Haematopoietic stem cell transplantation has been proposed as treatment for mitochondrial neurogastrointestinal encephalomyopathy, a rare fatal autosomal recessive disease due to TYMP mutations that result in thymidine phosphorylase deficiency. We conducted a retrospective analysis of all known patients suffering from mitochondrial neurogastrointestinal encephalomyopathy who underwent allogeneic haematopoietic stem cell transplantation between 2005 and 2011. Twenty-four patients, 11 males and 13 females, median age 25 years (range 10-41 years) treated with haematopoietic stem cell transplantation from related (n = 9) or unrelated donors (n = 15) in 15 institutions worldwide were analysed for outcome and its associated factors. Overall, 9 of 24 patients (37.5%) were alive at last follow-up with a median follow-up of these surviving patients of 1430 days. Deaths were attributed to transplant in nine (including two after a second transplant due to graft failure), and to mitochondrial neurogastrointestinal encephalomyopathy in six patients. Thymidine phosphorylase activity rose from undetectable to normal levels (median 697 nmol/h/mg protein, range 262-1285) in all survivors. Seven patients (29%) who were engrafted and living more than 2 years after transplantation, showed improvement of body mass index, gastrointestinal manifestations, and peripheral neuropathy. Univariate statistical analysis demonstrated that survival was associated with two defined pre-transplant characteristics: human leukocyte antigen match (10/10 versus <10/10) and disease characteristics (liver disease, history of gastrointestinal pseudo-obstruction or both). Allogeneic haematopoietic stem cell transplantation can restore thymidine phosphorylase enzyme function in patients with mitochondrial neurogastrointestinal encephalomyopathy and improve clinical manifestations of mitochondrial neurogastrointestinal encephalomyopathy in the long term.

    Human Natural Killer (NK) cells require at least two signals to trigger tumor cell lysis. Absence of ligands providing either signal 1 or 2 provides NK resistance. We manufactured a lysate of a tumour cell line which provides signal 1 to resting NK cells without signal 2. The tumor-primed NK cells (TpNK) lyse NK resistant Acute Myeloid Leukemia (AML) blasts expressing signal 2 ligands. We conducted a clinical trial to determine the toxicity of TpNK cell infusions from haploidentical donors. 15 patients with high risk AML were screened, 13 enrolled and 7 patients treated. The remaining 6 either failed to respond to re-induction chemotherapy or the donor refused to undergo peripheral blood apheresis. The conditioning consisted of fludarabine and total body irradiation. This was the first UK trial of a cell therapy regulated as a medicine. The complexity of Good Clinical Practice compliance was underestimated and led to failures requiring retrospective independent data review. The lessons learned are an important aspect of this report. There was no evidence of infusional toxicity. Profound myelosuppression was seen in the majority (median neutrophil recovery day 55). At six months follow-up, three patients treated in Complete Remission (CR) remained in remission, one patient infused in Partial Remission had achieved CR1, two had relapsed and one had died. One year post-treatment one patient remained in CR. Four patients remained in CR after treatment for longer than their most recent previous CR. During the 2 year follow-up six of seven patients died; median overall survival was 400 days post infusion (range 141–910). This is the first clinical trial of an NK therapy in the absence of IL-2 or other cytokine support. The HLA-mismatched NK cells survived and expanded in vivo without on-going host immunosuppression and appeared to exert an anti-leukemia effect in 4/7 patients treated.

The patient presented 30 days post HSCT with fever and lymphadenitis. Lymph node, blood, and gastric aspirates were positive for M. bovis. The patient received a prolonged treatment course with a combination of isoniazid, levofloxacin, and ethambutol. Her course was further complicated by granulomatous lymphadenitis and otitis media associated with M. bovis that developed during immune suppression taper and immune reconstitution. Ultimately, the patient recovered fully, in association with restoration of immune function, and has completed 12 months of therapy. PMID:24995715

    Relapse after allogeneic blood or marrow transplantation carries a very poor prognosis. Current strategies for management that include donor lymphocyte infusions (DLIs) and salvage chemotherapies are usually toxic and ineffective. Here we report the outcome of 10 patients with myeloid malignancies that received 5-azacytidine after a failed allogeneic bone marrow transplant. Of the 10 patients, 6 achieved a complete remission, 1 had stable disease, and 3 progressed after a median of 6 cycles administered. Only 1 patient has died (of disease progression), and no flares of graft-versus-host disease (GVHD) were observed with 5-azacytidine. As of latest follow-up, the median overall survival (OS) for the group was 422.5 days (127–1411). These results further suggest that 5-azacytidine is an active agent after failing an allogeneic bone marrow transplant, and prospective studies are warranted. PMID:20951817

    Heart failure is a life-limiting condition affecting over 40 million patients worldwide. Ischemic cardiomyopathy (ICM) is the most common cause. This study investigates in situ cardiac regeneration utilizing precision delivery of a novel mesenchymal precursor cell type (iMP) during coronary artery bypass surgery (CABG) in patients with ischemic cardiomyopathy (LVEF < 40 %). The phase IIa safety study was designed to enroll 11 patients. Preoperative scintigraphy imaging (SPECT) was used to identify hibernating myocardium not suitable for conventional myocardial revascularization for iMP implantation. iMP cells were implanted intramyocardially in predefined viable peri-infarct areas that showed poor perfusion, which could not be grafted due to poor target vessel quality. Postoperatively, SPECT was then used to identify changes in scar area. Intramyocardial implantation of iMP cells with CABG was safe with preliminary evidence of efficacy of improved myocardial contractility and perfusion of nonrevascularized territories resulting in a significant reduction in left ventricular scar area at 12 months after treatment. Clinical improvement was associated with a significant improvement in quality of life at 6 months posttreatment in all patients. The results suggest the potential for in situ myocardial regeneration in ischemic heart failure by delivery of iMP cells. PMID:27037806

    Hematopoietic stem cell transplantation (HSCT) is a highly effective procedure enabling long-term survival for patients with hematologic malignancy or heritable defects. Although there has been a dramatic increase in the success rate of HSCT over the last two decades, HSCT can result in serious, sometimes untreatable disease due to toxic conditioning regimens and Graft-versus-Host-Disease. Studies utilizing germline knockout mice have discovered several candidate genes that could be targeted pharmacologically to create a more favorable environment for transplant success. SHIP1 deficiency permits improved engraftment of hematopoietic stem-progenitor cells (HS-PCs) and produces an immunosuppressive microenvironment ideal for incoming allogeneic grafts. The recent development of small molecule SHIP1 inhibitors has opened a different therapeutic approach by creating transient SHIP1-deficiency. Here we show that SHIP1 inhibition (SHIPi) mobilizes functional HS-PC, accelerates hematologic recovery, and enhances donor HS-PC engraftment in both allogeneic and autologous transplant settings. We also observed the expansion of key cell populations known to suppress host-reactive cells formed during engraftment. Therefore, SHIPi represents a non-toxic, new therapeutic that has significant potential to improve the success and safety of therapies that utilize autologous and allogeneic HSCT. PMID:26052545

    Rejection after allogeneic bone marrow transplantation for Fanconi anemia (FA) is a complication with a high risk of mortality. We describe a patient who, following a second episode of rejection after a second allogeneic stem cell transplantation, was successfully treated with antilymphocyte globulin, followed by donor lymphocyte infusion. At three and a half years after donor lymphocyte infusion, she is alive with a Karnofsky score of 90%. Her molecular chimerism is of donor origin. Thus, donor lymphocyte infusion can be considered as a therapy option for rejection after allogeneic bone marrow transplantation for FA. PMID:14671621

    Only a few studies in children have evaluated the efficacy of prophylactic regimens using tacrolimus on acute graft-versus-host disease (aGVHD). As a result, optimal tacrolimus levels in children after matched sibling donor allogeneic hematopoietic cell transplantation (alloHCT) are not well defined. We measured the association between subtherapeutic levels (<10 ng/mL) during weeks 1 to 4 after alloHCT and the cumulative incidence of grades II to IV aGVHD in children. Additionally, we identified optimal lower cutoff levels for tacrolimus. Sixty patients (median age, 8 years) received tacrolimus/mycophenolate mofetil between March 2003 and September 2012. Twenty-three had a malignant disease and 37 nonmalignant disorders. The stem cell source included peripheral blood stem cells (n = 12) and bone marrow or cord blood (n = 48). Conditioning regimen varied. Specifically, 38.3% received a myeloablative regimen, 36.7% receiving a reduced-toxicity regimen, and 25% receiving a reduced-intensity regimen. Tacrolimus was initiated at .03 mg/kg/day via continuous i.v. infusion or .12 mg/kg/day orally. The dose was adjusted to maintain daily steady state concentrations within a range of 10 to 20 ng/mL. The overall incidence of grades II to IV aGVHD was 33.3%. On multivariate analysis, a mean tacrolimus level < 10 ng/mL during week 3 (P = .042; 95% confidence interval, 1.051 to 14.28) was significantly associated with increased incidence of grades II to IV aGVHD. Using weekly receiver operator curves, the optimal lower cutoff for tacrolimus levels was 10 to 11.2 ng/mL. Further prospective studies are warranted to study the incidence of aGVHD comparing the conventional tacrolimus levels of 5 to 15 versus 10 to 15 ng/mL. PMID:25536217

    Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a multisystemic autosomal recessive disease due to primary thymidine phosphorylase (TP) deficiency. To restore TP activity, we performed reduced intensity allogeneic stem cell transplantations (alloSCTs) in two patients. In the first, alloSCT failed to engraft, but the second achieved mixed donor chimerism, which partially restored buffy coat TP activity and lowered plasma nucleosides. Thus, alloSCT can correct biochemical abnormalities in the blood of patients with MNGIE, but clinical efficacy remains unproven. PMID:16971696

    Within the concept of reduced-intensity stem cell transplantation (RIST) there is a wide range of different regimens used, and little information is available on the clinical impact of chimerism status in patients conditioned with a busulfan-containing regimen. Therefore, we retrospectively reviewed lineage-specific chimerism and the subsequent clinical outcome in 117 patients (median age, 55 years; range: 29-68) who underwent busulfan-containing RIST. The conditioning regimen consisted of busulfan (oral 8 mg/kg or i.v. 6.4 mg/kg) and fludarabine (180 mg/m(2), n = 64) or cladribine (0.66 mg/kg, n = 53), with or without 2-4 Gy total-body irridiation (TBI) (n = 26) or antihuman T-lymphocyte immunoglobulin (ATG; 5-10 mg/kg; n = 31). Chimerism was evaluated with peripheral blood samples taken on days 30, 60, and 90 after transplantation by polymerase chain reaction (PCR)-based amplification of polymorphic short tandem repeat regions. The median follow-up of surviving patients was 1039 days (153-2535). The percent donor-chimerism was significantly higher in granulocyte than T cell fraction throughout the entire course, and the median (mean) values were, respectively, 100% (96%) versus 95% (83%), 100% (98%) versus 100% (89%), and 100% (98%) versus 100% (91%) at days 30, 60, and 90 after RIST. In a multivariate analysis, having received <2 types of chemotherapy regimens before RIST was the only factor that was significantly associated with low donor T cell chimerism (<60%) at day 30 (hazard ratio [HR]: 6.1; 95% confidence interval [CI], 2.1-18.4; P < .01). The median percentage of donor T cell chimerism at day 30 was 9% (0%-63%) in 5 patients who experienced graft failure, which was significantly lower than that (97%; 15%-100%) in the rest of the patients (P < .01). No correlation was found between the kinetics of T cell chimerism and the occurrence of acute or chronic GVHD (aGVHD, cGVHD).

    HHV-6 is an evolving pathogen in the field of AlloHCT. However, the impact of HHV-6 on AlloHCT outcomes remains to be elucidated. We studied the incidence and clinical impact of HHV-6 viremia in children following AlloHCT. One hundred consecutive children were monitored weekly by plasma PCR for the first 180 days following AlloHCT for HHV-6, CMV, EBV, and ADV. HHV-6 viremia was defined as plasma PCR >1000 viral copies/mL. The median age was nine yr. Following AlloHCT, 19% (95% CI 11.3-26.7%) of patients had HHV-6 viremia, with the highest incidence of reactivation (14/19, 73%) occurring during day +15-day +98. The proportion of platelet engraftment by day +180 was lower in patients with HHV-6 viremia (58%) than in those without HHV-6 viremia (82%), p = 0.028. Delay in neutrophil and platelet engraftment was not associated with HHV-6 viremia in multivariate analysis. Similarly, HHV-6 viremia was not associated with TRM in multivariate analysis (p = 0.15). In summary, HHV-6 viremia is prevalent in pediatric AlloHCT recipients. Based on our study results, we recommend that HHV-6 PCR should only be performed on clinical suspicion. PMID:26329541

    Iodine-131-metaiodiobenzylguanidine (131I-MIBG) therapy combined with allogeneic cord blood stem cell transplantation (SCT) was used to treat a 4-year-old girl with recurrent neuroblastoma. The patient experienced relapse 2 years after receiving first-line therapies, which included chemotherapy, surgical resection, irradiation, and autologous peripheral SCT. Although 131I-MIBG treatment did not achieve complete remission, the size of the tumor was reduced after treatment. Based on our findings, we suggest that 131I-MIBG treatment with myeloablative allogeneic SCT should be considered as first-line therapy for high-risk neuroblastoma patients when possible.

    Multiple Sclerosis (MS) is a frequent demyelinating immune-mediated disease of the central nervous system (CNS) that affects principally young adults and leads to severe physical and cognitive impairment. The current standard treatment makes use of the immune modulators beta-interferon, glatiramer acetate and natalizumab, or immunosuppressants such as mitoxantrone. However, these agents are only partially effective and in a number of patients fail to achieve satisfactory disease control. Autologous hematopoietic stem cell transplantation (HSCT) is being explored in the treatment of severe MS as a means of delivering high-dose immunosuppression followed by 'rescue' of the immuno-hematopoietic system with autologous HSC. The potential therapeutic benefit is based on the concept of so-called 'resetting' the immune system. The use of allogeneic HSCT as a possible therapeutic approach for severe MS is inspired by case reports of MS patients that underwent allogeneic HSCT for a concomitant hematological malignancy, and subsequently is supported by data from rodent models of MS. Allogeneic HSCT may offer specific therapeutic effects, such as the replacement of the autoreactive immune compartment by healthy allogeneic cells and the development of a graft-versus-autoimmunity (GVA) effect. Here, we review the currently available experimental and clinical evidence to support the role of autologous and allogeneic HSCT in MS. PMID:18541311

    Sickle cell disease is an inherited hematologic disorder that in its severe form can result in substantial morbidity and early mortality. Patients with this disorder can suffer from severe pain, lung disease, and strokes, resulting in chronic debilitating conditions, end organ dysfunction, and organ failure. The health care costs of caring for these chronically ill patients are substantial. Allogeneic transplantation is a modality that has the potential to cure these patients. To date, matched sibling donor transplantation is widely accepted as a standard of care for pediatric patients. Utilizing alternative donors for transplant is still under investigation, as is transplant for adult patients with sickle cell disease. This review focuses on the most recent data for hematopoietic cell transplantation for patients with sickle cell disease. PMID:26352583

    T-cells play an important role in the remission-maintenance in AML-patients (pts) after SCT, however the role of LAA- (WT1, PR1, PRAME) or minor-histocompatibility (mHag, HA1) antigen-specific CD4(+) and CD8(+)T-cells is not defined. A LAA/HA1-peptide/protein stimulation, cloning and monitoring strategy for specific CD8(+)/CD4(+)T-cells in AML-pts after SCT is given. Our results show that (1) LAA-peptide-specific CD8+T-cells are detectable in every AML-pt after SCT. CD8(+)T-cells, recognizing two different antigens detectable in 5 of 7 cases correlate with long-lasting remissions. Clonal TCR-Vβ-restriction exemplarily proven by spectratyping in PRAME-specific CD8(+)T-cells; high PRAME-peptide-reactivity was CD4(+)-associated, as shown by IFN-γ-release. (2) Two types of antigen-presenting cells (APCs) were tested for presentation of LAA/HA1-proteins to CD4(+)T-cells: miniEBV-transduced lymphoblastoid cells (B-cell-source) and CD4-depleted MNC (source for B-cell/monocyte/DC). We provide a refined cloning-system for proliferating, CD40L(+)CD4(+)T-cells after LAA/HA1-stimulation. CD4(+)T-cells produced cytokines (GM-CSF, IFN-γ) upon exposure to LAA/HA1-stimulation until after at least 7 restimulations and demonstrated cytotoxic activity against naive blasts, but not fibroblasts. Antileukemic activity of unstimulated, stimulated or cloned CD4(+)T-cells correlated with defined T-cell-subtypes and the clinical course of the disease. In conclusion we provide immunological tools to enrich and monitor LAA/HA1-CD4(+)- and CD8(+)T-cells in AML-pts after SCT and generate data with relevant prognostic value. We were able to demonstrate the presence of LAA-peptide-specific CD8(+)T-cell clones in AML-pts after SCT. In addition, we were also able to enrich specific antileukemic reactive CD4(+)T-cells without GvH-reactivity upon repeated LAA/HA1-protein stimulation and limiting dilution cloning. PMID:24315637

    Here we report a case of aggressive neuroendocrine tumor (NET), which is an extremely rare secondary solid tumor that occurs after allogeneic hematopoietic cell transplantation (allo-HSCT). A patient with chronic active Epstein-Barr virus infection received allo-HSCT from an HLA-DR two allele-mismatched unrelated donor. Four years later, he developed NET with multiple metastases. He received thoraco-abdominal irradiation as a conditioning regimen, and developed repeated episodes of intestinal graft-versus-host disease, for which he received long-term immunosuppressive therapy. Although these factors may be potential contributing factors to the development of secondary NET, the exact pathogenesis remains unclear. PMID:26711919

    Spinal fluid lymphocytes from multiple sclerosis (MS) patients and controls were stimulated with either autologous non-T cells or with allogeneic non-T cells followed by stimulation with autologous non-T lymphocytes. Cells responding to these stimuli were cloned and their proliferative responses to autologous and allogeneic MS and normal non-T cells were measured. Large numbers of clones with specific patterns of reaction to both autologous and allogeneic cells were obtained from lymphocytes in MS cerebrospinal fluid (CSF), but only occasionally from cells in control CSF. Patterns of responses among clones from a particular CSF were similar and often identical, which suggested that cells in MS CSF were relatively restricted in their specificities. Surface antigen phenotyping of the clones showed them to be predominantly OKT4+, with 13% OKT8+ and 11% OKT4+8+. Peripheral T cells that were stimulated and cultured in parallel with CSF cells were different in that they usually did not give rise to as many clones nor were their patterns of response similar. Many CSF clones were heteroclitic, that is they responded to particular allogeneic cells but not autologous cells. Lymphocytes in MS CSF thus appear to represent a selected population of cells with a high frequency of responsiveness to autologous and allogeneic antigens. Such responses may be evidence for immune regulation within the central nervous system or could represent responses to altered-self antigens. PMID:6237121

    Purpose Fludarabine monophosphate (fludarabine) is frequently administered to patients receiving a reduced-intensity conditioning regimen for allogeneic hematopoietic cell transplant (HCT) in an ambulatory care setting. These patients experience significant interpatient variability in clinical outcomes, potentially due to pharmacokinetic variability in 2-fluoroadenine (F-ara-A) plasma concentrations. To test such hypotheses, patient compliance with the blood sampling should be optimized by the development of a minimally intrusive limited sampling schedule (LSS) to characterize F-ara-A pharmacokinetics. To this end, we sought to create the first F-ara-A population pharmacokinetic model and subsequently a LSS. Experimental Design A retrospective evaluation of F-ara-A pharmacokinetics was conducted after one or more doses of daily IV fludarabine in 42 adult HCT recipients. NONMEM software was used to estimate the population pharmacokinetic parameters and compute the area under the concentration-time curve (AUC). Results A two compartment model best fit the data. A LSS was constructed using a simulation approach, seeking to minimize the scaled mean square error (sMSE) for the AUC for each simulated individual. The LSS times chosen were: 0.583 hour (hr), 1.5 hr, 6.5 hr and 24 hr after the start of the 30 minute fludarabine infusion. Conclusion The pharmacokinetics of F-ara-A in an individual HCT patient can be accurately estimated by obtaining 4 blood samples (using the LSS) and maximum a posteriori (MAP) Bayesian estimation. Conclusions These are essential tools for prospective pharmacodynamic studies seeking to determine if clinical outcomes are related to F-ara-A pharmacokinetics in patients receiving IV fludarabine in the ambulatory clinic.

    Stem cell transplantation is a generic term covering different techniques. However there is argument over the pros and cons of autologous and allogeneic transplants of mesenchymal stem cells (MSCs) for regenerative therapy. Given that the MSCs have already been proven to be safe in patients, we hypothesize that allogeneic transplantation could be more effective and cost-effective as compared to autologous transplantation specifically in older subjects who are the likely victims of degenerative diseases. This analysis is based on the scientific logic that allogeneic stem cells extracted in large numbers from young and healthy donors could be physiologically, metabolically and genetically more stable. Therefore stem cells from young donors may be expected to exhibit higher vigor in secreting trophic factors leading to activation of host tissue-specific stem cells and also be more efficient in remodeling the micro-environmental niche of damaged tissue.

    Acute lymphoblastic leukemia (ALL) persisting or relapsing following bone marrow transplantation (BMT) has a dismal prognosis. Success with chimeric antigen receptor (CAR) T cells offers an opportunity to treat these patients with leukemia-redirected donor-derived T cells, which may be more functional than T cells derived from patients with leukemia but have the potential to mediate graft-versus-host disease (GVHD). We, together with others, have previously demonstrated tumor-specific T-cell dysfunction in the allogeneic environment. Here, we studied CAR T-cell function following BMT using an immunocompetent murine model of minor mismatched allogeneic transplantation followed by donor-derived CD19-CAR T cells. Allogeneic donor-derived CD19-CAR T cells eliminated residual ALL with equal potency to those administered after syngeneic BMT. Surprisingly, allogeneic CAR T cells mediated lethal acute GVHD with early mortality, which is atypical for this minor mismatch model. We demonstrated that both allogeneic and syngeneic CAR T cells show initial expansion as effector T cells, with a higher peak but rapid deletion of allogeneic CAR T cells. Interestingly, CAR-mediated acute GVHD was only seen in the presence of leukemia, suggesting CAR-target interactions induced GVHD. Indeed, serum interleukin (IL)-6 was elevated only in the presence of both leukemia and CAR T cells, and IL-6 neutralization ameliorated the severity of GVHD in a delayed donor lymphocyte infusion model. Finally, allogeneic CD4(+) CAR T cells were responsible for GVHD, which correlated with their ability to produce IL-6 upon CAR stimulation. Altogether, we demonstrate that donor-derived allogeneic CAR T cells are active but have the capacity to drive GVHD. PMID:26660684

    The role of HLA amino acid (AA) polymorphism for the outcome of hematopoietic cell transplantation (HCT) is controversial, in particular for HLA class II. Here, we investigated this question in nonpermissive HLA-DPB1 T-cell epitope (TCE) mismatches reflected by numerical functional distance (FD) scores, assignable to all HLA-DPB1 alleles based on the combined impact of 12 polymorphic AAs. We calculated the difference in FD scores (ΔFD) of mismatched HLA-DPB1 alleles in patients and their 10/10 HLA-matched unrelated donors of 379 HCTs performed at our center for acute leukemia or myelodysplastic syndrome. Receiver-operator curve-based stratification into 2 ΔFD subgroups showed a significantly higher percentage of nonpermissive TCE mismatches for ΔFD >2.665, compared with ΔFD ≤2.665 (88% vs 25%, P < .0001). In multivariate analysis, ΔFD >2.665 was significantly associated with overall survival (hazard ratio [HR], 1.40; 95% confidence interval [CI], 1.05-1.87; P < .021) and event-free survival (HR, 1.39; 95% CI, 1.05-1.82; P < .021), compared with ΔFD ≤2.665. These associations were stronger than those observed for TCE mismatches. There was a marked but not statistically significant increase in the hazards of relapse and nonrelapse mortality in the high ΔFD subgroup, whereas no differences were observed for acute and chronic graft-versus-host disease. Seven nonconservative AA substitutions in peptide-binding positions had a significantly stronger impact on ΔFD compared with 5 others (P = .0025), demonstrating qualitative differences in the relative impact of AA polymorphism in HLA-DPB1. The novel concept of ΔFD sheds new light onto nonpermissive HLA-DPB1 mismatches in unrelated HCT. PMID:27162243

    Allogeneic cell therapy (allo-CT) is emerging as an effective treatment for patients relapsing after allogeneic bone marrow transplantation (BMT), indicating that tumor cells resisting chemoradiotherapy may still respond to immunocompetent allogeneic lymphocytes. We investigated possible graft-versus-tumor (GVT) effects in six patients with metastatic breast cancer that would be comparable to the graft-versus-leukemia (GVL) phenomenon occurring after allogeneic BMT in hematologic malignancies. The patients were cytoreduced with high-dose chemotherapy and autologous stem cell transplantation (ASCT), and were treated ambulatory with allo-CT consisting of adoptive transfer of HLA-matched donor peripheral blood lymphocytes (PBL) activated in vivo with human recombinant interleukin-2 (rIL-2). If no graft-versus-host disease (GVHD) developed, allo-CT was augmented with infusion of donor PBL, preactivated in vitro with rIL-2. Treatment was well tolerated, with low therapy-related toxicity in all patients. Two patients developed signs and symptoms compatible with GVHD grade I-II, one of whom shows no evidence of disease at more than 34 months out. In the remaining patients, progression-free survival following allo-CT ranged between 7 and 13 months. Allogeneic cell-mediated, cytokine-activated immunotherapy might be utilized for induction of GVT in metastatic breast cancer. A search for techniques to boost chimerism without severe GVHD is indicated. PMID:9557210

    Psychological issues following Hematopoietic Cell Transplantation (HCT) are unfortunately common. Literature specific to the transplant experience for the needs of adolescents and young adults (AYA) is lacking. The purpose of this article is to 1) describe the allogeneic transplant experience for AYA transplant patients during the first year following transplantation including demographic and treatment characteristics, 2) present AYA data obtained during and following a six-part post transplant discharge study, 3) illustrate typical AYA experiences using case studies and 4) propose AYA intervention strategies within Erickson’s Stages of Psychosocial Development. A Quality of Life (QOL) model provided both the research conceptual framework, and the content analysis framework for the qualitative research. Themes that emerged within each domain were the following: sexuality/fertility, fatigue, depression/poor coping/habits, adherence issues, use of technology, dependency issues, changes in roles/relationships, issues with school/education, financial issues, family problems/issues, miscellaneous, religion/spirituality, fear of future, uncertainty, life, death, more life appreciation. These data guide us for providing targeted interventions for the needs of this AYA population. This paper has presented literature and developmental theory, qualitative and qualitative data from an intervention study, and clinical cases in order to propose a developmental treatment model for AYA transplant patients. A coordinated and multidisciplinary approach is needed for the HCT patient who is an AYA. PMID:21966725

    The recognition by the immune system of nonself determinants on cells, tissues, or organs transplanted between genetically disparate members of the same species can lead to a potent allogeneic response that is responsible for rejection. We review here fundamental concepts that underlie the origins and biology of allorecognition in the mammalian immune system. We examine why and how T cells are alloreactive and discuss emerging evidence of allorecognition by innate immune cells. The nature of T cells (naïve vs. memory) and the alloantigen presentation pathways (direct, indirect, and semidirect) that initiate the allogeneic response are outlined. PMID:23906882

    Reticulated platelets (RP) are the youngest forms of platelets in blood and reflect the rate of bone marrow platelet production. In the present study, we used flow cytometric analysis to determine the percentage of RPs in patients undergoing allogeneic stem cell transplantation. We investigated 10 patients after transplantation from HLA identical siblings: five with acute myeloid leukemia (AML), four with chronic myeloid leukemia (CML), and one patient with myelodysplastic syndrome (MDS). Of the patients examined, four patients underwent allogeneic bone marrow transplantation and six patients underwent peripheral blood stem cell transplantation. It was observed that the initially reduced percentage of RPs (2.9 +/- 1.7%; mean +/- SD) was significantly higher (P = 0.0109) in all patients (13.6 +/- 6.4%) in the following 10-26 days. The RP percentage peak preceded the recovery of peripheral platelet count up to 45.6 x 10(9)/l on average by 3 days. We found no difference in RP% between the AML and CML patients but we did observe that in CML patients the RP percentage increased on average 7 days earlier than in AML patients. The elevated RP percentage reflects increased bone marrow regeneration and can be considered an additional marker of thrombopoietic recovery in the patients undergoing allogeneic stem cell transplantation.

    Fourteen cases of severe acyclovir-resistant herpes simplex virus type 1 (HSV-1) infection, 7 of which showed resistance to foscarnet, were diagnosed among 196 allogeneic stem cell transplant recipients within a 29-month period. Recipients of unrelated stem cell transplants were at higher risk. All patients received foscarnet; 8 subsequently received cidofovir. Strains were initially foscarnet-resistant in 3 patients and secondarily so in 4 patients. In vitro resistance to acyclovir or foscarnet was associated with clinical failure of these drugs; however, in vitro susceptibility to foscarnet was associated with complete response in only 5 of 7 patients. No strain from any of the 7 patients was resistant in vitro to cidofovir; however, only 3 of 7 patients achieved complete response. Therefore, acyclovir- and/or foscarnet-resistant HSV-1 infections after allogeneic stem cell transplantation have become a concern; current strategies need to be reassessed and new strategies must be evaluated in this setting.

    Background and Objectives Dipeptidyl peptidase-4 (DPP4) inhibition is a potential strategy to increase the engraftment rate of hematopoietic stem/progenitor cells. A recent clinical trial using sitagliptin, a DPP4 inhibitor approved for type 2 diabetes mellitus, has shown to be a promising approach in adults with hematological malignancies after umbilical cord blood (UCB) hematopoietic cell transplant (HCT). Based on data from this clinical trial, a semi-mechanistic model was developed to simultaneously describe DPP4 activity after multiple doses of sitagliptin in subjects with hematological malignancies after a single-unit UCB HCT. Methods The clinical study included 24 patients that received myeloablative conditioning followed by 4 oral sitagliptin 600mg with single-unit UCB HCT. Using a nonlinear mixed effects approach, a semi-mechanistic pharmacokinetic/pharmacodynamic model was developed to describe DPP4 activity from this trial data using NONMEM 7.2. The model was used to drive Monte-Carlo simulations to probe various dosage schedules and the attendant DPP4 response. Results The disposition of sitagliptin in plasma was best described by a 2-compartment model. The relationship between sitagliptin concentration and DPP4 activity was best described by an indirect response model with a negative feedback loop. Simulations showed that twice a day or three times a day dosage schedules were superior to once daily schedule for maximal DPP4 inhibition at the lowest sitagliptin exposure. Conclusion This study provides the first pharmacokinetic/pharmacodynamic model of sitagliptin in the context of HCT, and provides a valuable tool for exploration of optimal dosing regimens, critical for improving time to engraftment in patients after UCB HCT.

    Comparisons without hematopoietic cell transplantation (HCT) to myeloablative (MAC) or reduced-intensity HCT (RIC) for adults with acute lymphoblastic leukemia (ALL) in first minimal-residual-disease negative remission (MRD(Neg) CR1) are limited. Further, the importance of MRD(Neg) following salvage therapy (MRD(Neg) CR2+) is unknown. We evaluated 89 patients in MRD(Neg) CR1 after adult-inspired treatment: 33 received MAC (12 Philadelphia chromosome [Ph]+), 17 received RIC (13 Ph+), and 39 Deferred HCT (3 Ph+). Three-year overall survival (OS) estimates for MAC, RIC, and Deferred HCT were 71%, 69%, and 68%, while 3-year event-free survival (EFS) estimates were 65%, 54%, and 28%, respectively. Further, HCT in MRD(Neg) CR1 performed similarly to MRD(Neg) CR2+: 3-year OS estimates were 70% and 69%, and 3-year EFS estimates were 62% and 62%, respectively. In conclusion, adults with ALL in MRD(Neg) CR1 following adult-inspired therapy had similar OS with or without HCT, and HCT in MRD(Neg) CR2 + can yield long-term survival. PMID:27002921

    Early and late endocrine disorders are among the most common complications in survivors after hematopoietic allogeneic- (allo-) and autologous- (auto-) stem cell transplant (HSCT). This review summarizes main endocrine disorders reported in literature and observed in our center as consequence of auto- and allo-HSCT and outlines current options for their management. Gonadal impairment has been found early in approximately two-thirds of auto- and allo-HSCT patients: 90-99% of women and 60-90% of men. Dysfunctions of the hypothalamus-pituitary-growth hormone/insulin growth factor-I axis, hypothalamus-pituitary-thyroid axis, and hypothalamus-pituitary-adrenal axis were documented as later complicances, occurring in about 10, 30, and 40-50% of transplanted patients, respectively. Moreover, overt or subclinical thyroid complications (including persistent low-T3 syndrome, chronic thyroiditis, subclinical hypo- or hyperthyroidism, and thyroid carcinoma), gonadal failure, and adrenal insufficiency may persist many years after HSCT. Our analysis further provides evidence that main recognized risk factors for endocrine complications after HSCT are the underlying disease, previous pretransplant therapies, the age at HSCT, gender, total body irradiation, posttransplant derangement of immune system, and in the allogeneic setting, the presence of graft-versus-host disease requiring prolonged steroid treatment. Early identification of endocrine complications can greatly improve the quality of life of long-term survivors after HSCT. PMID:24883377

    A high resolution spectrometer for the 2m Himalayan Chandra Telescope (HCT) at Indian Astronomical Observatory (IAO) Hanle, is being built to meet the observational requirement of many advanced areas in astronomy requiring high spectral resolution. This instrument is based upon a modern design using a white pupil concept which has been adopted in several contemporary high resolution spectrometers. This design is known to reduce light losses due to vignetting and also provides the full spectral coverage (350nm-1000nm) in a single CCD frame. This design also incorporates additional features like image-slicer which would result in very high light efficiency. A peak throughput of 20% in visual range and throughput of 8% is expected at extreme blue and red wavelengths. The spectrometer would give resolutions of 60,000 and 30,000 in two resolution modes. In this contribution we describe the instrument and its environment and give an update on its development and science programs we propose to undertake.

    Purpose To determine CD133+ cells defined as cancer stem cells (CSCs) in colon cancer, we examined whether CD133+ clones in HCT116 demonstrate known features of CSCs like sphere-forming ability, chemodrug-resistance, and metastatic potential. Methods Magnetic cell isolation and cell separation demonstrated that <1% of HCT116 cells expressed CD133, with the remaining cells being CD133- clones. In colon cancer cells, radioresistance is also considered a CSC characteristic. We performed clonogenic assay using 0.4 Gy γ-irradiation. Results Interestingly, there were no differences between HCT116 parental and HCT116 CD133+ clones when the cells comprised 0.5% of the total cells, and CD133- clone demonstrated radiosensitive changes compared with parental and CD133+ clones. Comparing gene expression profiles between sphere-forming and nonforming culture conditions of HCT116 subclones by whole RNA sequencing failed to obtain specific genes expressed in CD133+ clones. Conclusion Despite no differences of gene expression profiles in monolayer attached culture conditions of each clone, sphere-forming conditions of whole HCT116 subclones, parental, CD133+, and CD133- increased 1,761 coding genes and downregulated 1,384 genes related to CSCs self-renewal and survival. Thus, spheroid cultures of HCT116 cells could be useful to expand colorectal CSCs rather than clonal expansion depending on CD133 expressions. PMID:27073788

  7. [Medication of the month. Exforge HCT: combination of amlodipine besylate, valsartan and hydrochlorothiazide in a single tablet].

    Because of the multifactorial nature of hypertension, most patients require combination therapy to achieve blood pressure control. Very often the antihypertensive regimen includes a renin-angiotensin system blocker, a calcium channel blocker, and a diuretic. Currently, several associations combining two antihypertensive agents with complementary mechanisms of action are available. These combination therapies are more efficient to control blood pressure through synergistic and additive effects, can reach target blood pressure more quickly, are likely to attenuate the side effects of each molecule, and could improve patient adherence. Exforge HCT is the first fixed-dose combination of three antihypertensive drugs including amlodipine besylate, valsartan and hydrochlorothiazide (HCTZ) in a single pill. The association of these three drugs improves, with an equal tolerance, blood pressure control compared to dual therapies (valsartan/HCTZ, amlodipine/valsartan, or HCTZ/amlodipine). This triple therapy attenuates the diuretic-induced hypokalemia. The benefits of triple therapy over dual therapy are observed regardless of age, sex, race, ethnicity, or baseline mean sitting systolic blood pressure. Exforge HCT is currently indicated for the treatment of essential hypertension, as replacement therapy for adult patients whose blood pressure is adequately controlled by the combination of amlodipine, valsartan and HCTZ.

    A lung computed tomography (CT) scan is essential for diagnosing lung diseases in hematopoietic stem cell transplantation (HSCT) recipients. As a result, lung CT scans are increasingly prescribed in the early phase after allogeneic HSCT, with no assessment of the added value for global patient management. Among 250 patients who underwent allogeneic HSCT in our center over a 2-year period, we evaluated 68 patients who had at least 1 lung CT scan within the first 30 days post-transplantation. The median interval between allogeneic HSCT and lung CT scan was 8.5 days. Patients who underwent an early lung CT scan were more immunocompromised and had a more severe course. Fever was the main indication for the CT scan (78%). The lung CT scan was abnormal in 52 patients, including 17 patients who had an abnormal pre-HSCT CT scan. A therapeutic change was noted in 37 patients (54%) within 24 hours after the lung CT scan. The main changes included the introduction of corticosteroids (n = 23; 62%), especially in patients with a normal CT scan (89%). In univariate models, we found that a normal pretransplantation CT scan (P = .002), the absence of either dyspnea (P = .029) or hypoxemia (P = .015), and a serum C-reactive protein level <10 mg/L (P = .004) were associated with a normal post-HSCT lung CT scan. We found that the association of these variables could predict the normality of early post-HSCT lung CT scans. Pretransplantation lung CT scans are useful for the interpretation of subsequent lung CT scans following allogeneic HSCT, which are frequently abnormal. Early post-HSCT lung CT scans are helpful in patient management, but prescriptions could be more targeted. PMID:27189110

    Chronic myeloid leukemia (CML) in children and young adults is uncommon. Young patients have long life expectancies and low morbidity with hematopoietic cell transplantation (HCT). Prolonged tyrosine kinase inhibitor (TKI) use may cause significant morbidity. In addition, indication for HCT in patients in the first chronic phase is not established. We hence retrospectively evaluated outcomes in 449 CML patients with early disease receiving myeloablative HCT reported to the CIBMTR. We analyzed various factors affecting outcome, specifically the effect of age and pre-HCT TKI in pediatric patients (age < 18 years, n = 177) and young adults (age 18 to 29 years, n = 272) with the goal of identifying prognostic factors. Post-HCT probability rates of 5-year overall survival (OS) and leukemia-free survival (LFS) were 75% and 59%, respectively. Rates of OS and LFS were 76% and 57% in <18-year and 74% and 60% in 18- to 29-year group, respectively, by univariate analysis (P = .1 and = .6). Five-year rates of OS for HLA matched sibling donor (MSD) and bone marrow (BM) stem cell source were 83% and 80%, respectively. In multivariate analysis there was no effect of age (<18 versus 18 to 29) or pre-HCT TKI therapy on OS, LFS, transplant related mortality, or relapse. Favorable factors for OS were MSD (P < .001) and recent HCT (2003 to 2010; P = .04). LFS was superior with MSD (P < .001), BM as graft source (P = .001), and performance scores > 90 (P = .03) compared with unrelated or mismatched peripheral blood stem cells donors and recipients with lower performance scores. Older age was associated with increased incidence of chronic graft-versus-host disease (P = .0002). In the current era, HCT outcomes are similar in young patients and children with early CML, and best outcomes are achieved with BM grafts and MSD. PMID:26964698

    The role of allogeneic stem cell transplant in advanced acute promyelocytic leukemia patients who received standard first- and second-line therapy is still unknown. We report the outcome of 31 acute promyelocytic leukemia patients (median age 39 years) who underwent allogeneic transplant in second remission (n=15) or beyond (n=16). Sixteen patients were real-time polymerase chain reaction positive and 15 negative for PML/RARA pre-transplant. The 4-year overall survival was 62% and 31% for patients transplanted in second remission and beyond, respectively (P=0.05), and 64% and 27% for patients with pre-transplant negative and positive real-time polymerase chain reaction, respectively (P=0.03). The 4-year cumulative incidence of relapse was 32% and 44% for patients transplanted in second remission and beyond, respectively (P=0.37), and 30% and 47% for patients transplanted with negative and positive real-time polymerase chain reaction, respectively (P=0.30). Transplant-related mortality was 19.6%. In conclusion, allogeneic transplant is effective in advanced acute promyelocytic leukemia in the all-trans-retinoic acid and arsenic trioxide era, and should be considered once relapse is diagnosed.

    Bullous pemphigoid (BP) is an autoimmune skin disorder characterized by subepidermal blisters due to deposit of autoantibody against dermal basement membrane protein. It has been reported that BP can occur after allogeneic hematopoietic stem cell transplantation (HSCT). We describe a patient with BP having autoantibody against BP180 after unrelated-donor HSCT against T lymphoblastic leukemia. The patient was treated with steroid leading to complete resolution of BP, but T lymphoblastic leukemia progressed rapidly after steroid hormone treatment. Given that immunosuppressant may reduce graft-versus-tumor effect, immunomodulatory agents such as nicotinamide and tetracycline, erythromycin, and immunoglobulin may be appropriate as soon as typical blister lesions are seen after HSCT.

    In the present study we describe the incidence, clinical course, and management of avascular necrosis of bone following allogeneic bone marrow transplantation, and identify risk factors related to its development. All patients developing avascular necrosis of bone after allogeneic bone marrow transplantation between January 1974 and September 1992 were included in the analysis and were studied using the Hôpital Saint Louis Bone Marrow Transplant Database and hospital records. 27/727 allogeneic transplant recipients developed avascular necrosis leading to an 8.1% incidence at 5 years, by product limit estimate, ranging from 5% to 11.2%. Symptoms developed 119-1747 d (median 398 d) after transplantation. In these 27 patients a total of 52 joints were affected (mean 1.92 per patient, range 1-7). The hip joint was most often affected (69% of patients). All patients had joint pain that led to diagnosis by means of standard radiographs with or without the help of technetium-99 scans and/or magnetic resonance imaging. All but three patients received steroid therapy for acute graft-versus-host disease. Among 10 factors tested, three were shown to be significantly linked to an increased risk for developing avascular necrosis by multivariate analysis: male gender (relative risk (RR) 4.72, P = 0.002), age older than 16 (RR = 3.87, P = 0.004), and acute graft-versus-host disease requiring steroid therapy (RR = 6.30, P = 0.0002). 10 patients (37%) required joint replacement within 19 months (range 2-42) following diagnosis of avascular necrosis. In conclusion, avascular necrosis of bone is a frequent late complication of allogeneic bone marrow transplantation causing significant morbidity and requiring replacement surgery in one-third of affected patients. In this 18-year single-centre survey, older age, male gender and steroid therapy given for acute graft-versus-host disease were shown to independently increase the risk of avascular necrosis of bone.

    Voriconazole is an established first-line agent for treatment of invasive fungal infections in patients undergoing allogeneic stem cell transplantation (ASCT). It is associated with the uncommon complication of periostitis. We report this complication in a 58-year-old female undergoing HSCT. She was treated with corticosteroids with minimal improvement. The symptoms related to periostitis can mimic chronic graft-versus-host disease in patients undergoing HSCT and clinicians should differentiate this from other diagnoses and promptly discontinue therapy.

    Prospective validation of the hematopoietic cell transplantation-comorbidity index (HCT-CI) using contemporary patients treated with HCT across the Unites States is necessary to confirm its widespread applicability. We performed a prospective observational study including all patients (8115 recipients of allogeneic and 11,652 recipients of autologous HCT) who underwent first HCT that was reported to the CIBMTR between 2007 and 2009. In proportional hazards models, increased HCT-CI scores were independently associated with increases in hazard ratios for NRM (p<0.0001) and overall mortality (p<0.0001) among recipients of allogeneic HCT. HCT-CI Scores of ≥3 were uniformly associated with higher risks for outcomes in both allogeneic and autologous HCT, and all subgroups regardless of diagnoses, age, and conditioning intensity. Recipients of allogeneic HCT with scores of 1–2 who were aged <18 or were treated with lower intensity conditioning regimens had similar outcomes compared to those with score 0. Higher risks for overall mortality, but not for NRM, were observed among recipients of autologous HCT with scores of 1–2 versus 0. Our results confirm the validity the HCT-CI in both allogeneic and autologous HCT. The index should be used as a valid standard-of-care health measure in counseling patients for HCT, in clinical trial design, and in adjusting outcome analyses. PMID:25862591
