Abstract Abstract 1259 Following allogeneic hematopoietic stem cell transplantation (allo-HSCT), EBV reactivation and EBV lymphoprolipherative disease (LPD) are well recognized complications. To date, few data has been reported regarding the features of EBV LPD following RIC allo-HSCT. The aim of this study was to define the incidence and risk factors of EBV reactivation in 175 consecutive adult patients undergoing RIC allo-HSCT between January 2005 and June 2009 in our institution and to assess its impact on clinical outcome. In this series, the median age of recipients was 56 (range 18–71) years. In all, 85 patients (49%) had a myeloid malignancy, whereas 86 (49%) patients were diagnosed with lymphoid malignancies. The remaining 4 patients (2%) were treated for severe aplastic anemia. In total, 165 patients (94%) received peripheral blood stem cells (PBSC) whereas 10 patients (6%) received a bone marrow (BM) graft. 84 grafts (48%) were obtained from HLA identical sibling donors, 80 (46%) from HLA matched unrelated donors and 11 (6%) from 1 Ag HLA mismatched unrelated donors. The conditioning regimen associated fludarabine, busulfan, and ATG in 107 cases (61%), while 37 patients (21%) received fludarabine and low-dose TBI. The remaining 31 patient (18%) received different chemotherapy-based RIC regimens. EBV reactivation was defined as any EBV PCR load above 1000 copies of EBV DNA /105 cells. EBV LPD was defined as biopsy or autopsy proven post-transplantation lymphoma, or reactivation along with computerized tomography nodal or soft tissue abnormalities consistent with LPD. Patients with EBV viral load >1000 copies/105 cells on at least two consecutive occasions were treated with rituximab at a dose of 375 mg/m2 weekly until clearance of viremia. In our series, the median time to neutrophil recovery (absolute neutrophil count >0.5×109/L) was 17 (range, 6–48) days. Clinically significant grade II to IV acute GVHD occurred in 61 of cases (35%) and severe grade III to IV acute GVHD occurred in 37 of cases (21%). The cumulative incidence of EBV reactivation at 6 months after allo-HSCT was 15% (95% CI, 10–21%). EBV reactivation was observed at a median of 58 (range 0–930) days after allo-HSCT, with 27 (79%) of reactivations occurring during the first 6 months. In 141 patients (81%), the EBV load remained less than 1000 EBV copies/105 cells at all time. The remaining 34 patients (19%) experienced at least one EBV reactivation episode. Among these 34 patients, 17 patients had an EBV load superior to 1000/105 cells at a single time point after allo-HSCT. In these 17 cases, there were no concomitant clinical symptoms and the EBV load normalized spontaneously. The 17 patients who had EBV DNA levels exceeding 1000 copies/105 cells on 2 or more occasions were pre-emptively treated with a median number of 3 (range, 1–4) rituximab infusions which resulted in complete clearance of EBV viremia in all, but one patient (97%). This patient was severely immunosupressed, receiving three different immunosupressive agents and experienced both EBV and adenovirus (ADV) infection. This patient had symptoms mainly related to ADV infection, and died of multiorgan failure. Most importantly, none of the patients from this series developed EBV induced LPD. With a median follow-up of 655 (range, 92–1542) days post allo-HSCT among surviving patients, 104 patients (59%) were still alive and the overall survival (OS) was 47% at 4 years. There was no statistically significant difference in terms of OS or transplant related mortality (TRM) between patients who experienced an EBV reactivation and patients who did not (OS: log rank test, p=0.62; TRM: Gray test, p=0.99). In univariate analysis for risk factors associated with EBV reactivation only the use of ATG as part of the RIC regimen prior to allo-HSCT was significantly different between subgroups with and without EBV reactivation (Fisher's exact test, p=0.006). In the multivariate analysis, the use of ATG remained the only independent risk factor associated with EBV reactivation (Fine and Gray test; RR=4.9; 95%CI, 1.1–21.0; p=0.03). In all, we conclude that patients undergoing RIC allo-HSCT using ATG as part of the preparative regimen are at higher risk for EBV reactivation. However, this did not translate into a significant impact on outcome since monitoring of EBV viral load with quantitative PCR and early systematic pre-emptive rituximab therapy allowed for significantly reducing the risk of EBV-related LPD. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction Autoimmune hemolytic anemia (AIHA) is the most commonly reported autoimmune complication following hematopoietic stem cell transplantation (HSCT) with incidence of 2-6%. The risk factors and pathogenesis remain poorly understood. Treatment often requires multiple therapeutic agents with variable efficacy and outcome. However no study to date has shown whether AIHA directly results in increased mortality. In order to better understand the risk factors, mortality and management of post-HSCT AIHA, we carried out a retrospective analysis of 533 allogeneic HSCTs in adult patients performed at King's College Hospital between 2005-2011. Method The median follow-up period after HSCT was 31 months (range 2.9 – 100 months). The primary endpoint was the onset of AIHA, defined by positive direct agglutinin test (DAT) arising after the HSCT, with biochemical markers of hemolysis (raised serum lactate dehydrogenase (LDH), reduced haptoglobin, or spherocytes on the blood film). Hemolysis was considered significant if the drop in hemoglobin was more than 20 g/l. Cases of DAT positivity due to ABO antibodies, as well as those with history of AIHA or positive DAT prior to HSCT were excluded. Potential risk factors for development of AIHA were calculated with univariate followed by multivariate analysis comparisons of incidence of AIHA for each clinical stratum. Kaplan-Meier method was used to compare mortality caused by AIHA against overall mortality (OM), and transplant-related mortality (TRM). AIHA was modelled as a time-dependent variable when estimating mortality. All patients alive at last follow-up who did not develop AIHA were censored. Results We identified 19 cases of AIHA following 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 (p = 0.026; Hazard Ratio = 5.28, 95% CI = 1.22 – 22.9), and concordant sex between HSCT recipients and donors (p = 0.045; Hazard Ratio = 3.52; 95% CI = 1.03 – 12.1). No significant association was observed between AIHA and the following eight factors: recipient gender; primary hematological disease; source of hematopoietic stem cells; conditioning regimen (alemtuzumab/ATG versus non-alemtuzumab/ATG, and reduced intensity versus myeloablative); HLA mismatch between donor/recipient; ABO mismatch; recipient CMV status; and concurrent chronic GvHD. AIHA patients also exhibited high frequency of simultaneous alloimmunization to Rh antigens coinciding with the onset of AIHA, which was not due to difference in transfusion rates, and not observed in the population who tested negative for DAT. Majority of AIHA patients (14/19; 72%) required multiple agents for treatment, but only 9/19 (47%) cases achieved complete resolution of AIHA (1 with intravenous immunoglobulin; 2 with prednisolone alone; 6 with rituximab in combination with other agents). The median survival from onset of AIHA was 487 days (range 26 – 1977 days). We compared the mortality of the AIHA versus non-AIHA population that survived beyond the median time of onset for AIHA (202 days). Patients with post-transplant AIHA had a higher OM (p = 0.006, Hazard Ratio = 2.37, 95% CI = 1.28 – 4.39), 1-year OM of 22% versus 10% (p = 0.04) and 1-year TRM of 18% versus 4% (p = 0.001), respectively (Figure 1). 36% (4/11 cases) of deaths were attributable to AIHA. Conclusion The overall incidence of AIHA following allogeneic HSCT in our study was 3.6%. The risk factors associated with AIHA were receiving HSCT from unrelated donors, and matched gender between the donor/recipient, which has not been previously reported. We observed an association between allo and autoimmunization in the AIHA patients, suggesting a common immune defect underlying both phenomena. The most effective treatment was a combination regimen of rituximab with prednisolone or other immunosuppressive agents. The overall mortality rate for our AIHA patients was high at 53% (10/19 cases), with AIHA as a cause of death in 36% of deceased patients. We have shown that AIHA following HSCTs indeed leads to increased mortality with over 2 fold higher OM in the patients with AIHA. Figure 1 Figure 1. Disclosures McLornan: Novartis: Research Funding.

Abstract Purpose The success of allogeneic hematopoietic stem cell transplantation (HSCT) is compromised by complications such as infection, relapse, and graft-versus-host disease (GVHD). The investigation of non-HLA immunogenetics, particularly of cytokines, could identify predictors of an unfavorable outcome after allogeneic HSCT. In this study, we examined the impact of single nucleotide polymorphisms (SNPs) within the promoter region of interleukin 6 (IL6) on the development of GVHD after pediatric allogeneic HSCT. Methods In this retrospective analysis, we included 320 pediatric patients with a median age of 10 years who underwent an allogeneic HSCT and their respective donors. We used TaqMan real-time polymerase chain reaction to analyze the SNPs IL6-174 (G/C) and IL6-597 (G/A). The IL6-174 polymorphism was examined in 300 recipients and 295 donors. The IL6-597 polymorphism was analyzed in 299 recipients and 296 donors. We investigated the influence of the IL6-174 and IL6-597 polymorphisms on overall survival, event-free survival, relapse incidence, transplant-related mortality, and the occurrence of GVHD. Results G polymorphism at position 174 of the recipient IL6 gene was associated with a higher incidence of acute GVHD (GG vs. GC/CC; P = 0.024). Patients with IL6-597 GG genotype developed acute GVHD more frequently than individuals with an A allele (GG vs. GA vs. AA; P = 0.013). IL6-174 GG homozygous recipients had a more frequent occurrence of chronic GVHD (GG vs. GC/CC; P = 0.049). We observed a significant increased risk of chronic GVHD in recipients with IL6-597 GG genotype (GG vs. GA vs. AA; P = 0.043). Polymorphisms of donors did not affect the incidence of acute GVHD and chronic GVHD. In multivariate analysis, the IL6-174 and IL6-597 SNPs were independent significant risk factors for acute GVHD (P = 0.030; P = 0.007, respectively) as well as for chronic GVHD (P = 0.045; P = 0.015, respectively). In addition, older age at time of transplantation turned out to be a significant risk factor for chronic GVHD (P = 0.003). Conclusion Our study identified the IL6-174 and IL6-597 GG genotypes of pediatric allogeneic HSCT recipients as genetic risk factors for the development of acute GVHD and chronic GVHD. After evaluations in further studies, these findings could implicate the adjustment of prophylactic measures to reduce the occurrence of acute GVHD and chronic GVHD.

Abstract Objectives The early and late complications after hematopoietic stem cell transplantation (HSCT) determine the patients’ prognosis and life quality. We aim to determine the metabolic syndrome development frequency after HSCT in children to find out the risk factors and compare them with healthy adolescents. Methods Thirty-six children who underwent HSCT at least two years ago were analyzed prospectively and cross-sectionally. Our study included 18 healthy children between the ages of 11 and 17 as a control group. All of the cases were assessed in terms of metabolic syndrome (MS) through the use of Modified WHO Criteria. Results The patients’ median age was 10.6 (5.1–17) years, the median time of follow-up after HCST was 4.1 (2–13.5) years and 70% were male. Two cases were diagnosed with MS (5.6%). When considered in terms of the sub-components of MS, 2 cases (5.6%) were found to have obesity, 17 cases (47%) abnormal glucose tolerance, 11 cases (30.7%) dyslipidemia, and 3 cases (8.6%) hypertension. The MS rate was not different when compared with the 11–17 year-old healthy control group (0 vs. 11%, p=0.48). Myeloablative conditioning regimen (65 vs. 20%) and the increased age at which HSCT was performed were considered to be risk factors in terms of insulin resistance (p=0.025 and 0.002). Conclusions Age and conditioning regimens were found to be the risk factors for insulin resistance development. The long-term follow-up of the cases who had undergone HSCT in childhood in terms of MS and its sub-components is important in order to increase life quality.

Abstract Background Mesenchymal stromal cells (MSCs) are an emerging prophylaxis option for graft-versus-host disease (GVHD) in haplo-identical hematopoietic stem cell transplantation (haplo-HSCT) recipients with severe aplastic anemia (SAA), but studies have reported inconsistent results. This systematic review and meta-analysis evaluates the efficacy of MSCs as prophylaxis for GVHD in SAA patients with haplo-HSCT. Methods Studies were retrieved from PubMed, EMBASE, Cochrane, Web of Science, and http://clinicaltrials.gov from establishment to February 2020. Twenty-nine single-arm studies (n = 1456) were included, in which eight (n = 241) studies combined with MSCs and eleven (n = 1215) reports without MSCs in haplo-HSCT for SAA patients. The primary outcomes were the incidences of GVHD. Other outcomes included 2-year overall survival (OS) and the incidence of cytomegalovirus (CMV) infection. Odds ratios (ORs) were calculated to compare the results pooled through random or fixed effects models. Results Between MSCs and no MSCs groups, no significant differences were found in the pooled incidences of acute GVHD (56.0%, 95% CI 48.6–63.5% vs. 47.2%, 95% CI 29.0–65.4%; OR 1.43, 95% CI 0.91–2.25; p = 0.123), grade II–IV acute GVHD (29.8%, 95% CI 24.1–35.5% vs. 30.6%, 95% CI 26.6–34.6%; OR 0.97, 95% CI 0.70–1.32; p = 0.889), and chronic GVHD (25.4%, 95% CI 19.8–31.0% vs. 30.0%, 95% CI 23.3–36.6%; OR 0.79, 95% CI 0.56–1.11; p = 0.187). Furtherly, there was no obvious difference in 2-year OS (OR 0.98, 95% CI 0.60–1.61; p = 1.000) and incidence of CMV infection (OR 0.61, 95% CI 0.40–1.92; p = 0.018). Conclusions Our meta-analysis indicates that the prophylactic use of MSC co-transplantation is not an effective option for SAA patients undergoing haplo-HSCT. Hence, the general co-transplantation of MSCs for SAA haplo-HSCT recipients may lack evidence-based practice.

Abstract Background and Aims The aim of the study is to investigate the incidence and risk factors of hypertension (HT) and chronic kidney disease (CKD) in patients who had hematopoietic stem cell transplantation (HSCT) during their childhood. Method Patients who had HSCT between January 2010-2019 with a minimum follow-up period of 6 months were included in the study. Data regarding renal complications were collected from the medical records of the patients. Guidelines of European Society of Hypertension (ESH) and American Academy of Pediatrics (APA) were used for the evaluation of hypertension. 24-hr ambulatory blood pressure monitoring (ABPM) was performed in children older than 5 years of age (68 patients). Ambulatory hypertension is diagnosed when systolic and/or diastolic blood pressure (BP) load is higher than 25%. Ambulatory prehypertension is diagnosed when mean systolic and/or diastolic BP is less than 95th percentile with systolic and/or diastolic BP load higher than 25%. Results A total of 72 patients (41 males and 31 females) were included in the study. The mean age of the patients at last visit was 10.8±4 years. ABPM revealed ambulatory HT in 6 patients (8.8%) and ambulatory prehypertension in 12 patients (17.6%). Office BP revealed HT in 3 patients (4.2%) and increased BP in four patients (5.6%) according to APA guideline (2017). In cohort, 12 patients with normal office BP (according to APA guideline) had ambulatory prehypertension or hypertension with ABPM. Office BP revealed HT in 1 patient (1.4%) and high-normal BP in 3 patients (4.2%) according to ESH guideline. In cohort, 15 patients with normal office BP (according to ESH guideline) had ambulatory prehypertension or hypertension with ABPM (Table 1). After a mean follow-up period of 4.4±2.5 years, CKD developed in 8 patients (11.1%). Patients with chronic graft-versus-host disease, with HLA-mismatched HSCT and/or transplantation of peripheric or cord blood hematopoietic stem cells had increased risk of CKD (p=0.041, p=0.033 and p=0.002, respectively). Conclusion Patients with HSCT should be regularly followed for the development of HT and ABPM should be used on regular basis. Patients with risk factors should be closely monitored for the development of CKD.
