Background: Survivors of hematopoietic stem cell transplantation (HSCT) are 2 to 4 times more likely to develop cardiovascular diseases, accounting for 2-11% of mortality among long-term survivors. Early diagnosis and treatment of modifiable risk factors, such as arterial hypertension, are imperative in this group of patients. The aim of this study is to evaluate the prevalence and associated factors for arterial hypertension following HSCT in a Colombian population. Methods: A retrospective study was conducted in 220 consecutive adult HSCT recipients who underwent transplantation between 2009 and 2017 at a third level referral center in Colombia. Blood pressure data, from two different measures, were collected at 7 time points: day of mobilization for autologous HSCT (auto-HSCT) and day 0 before infusion for allogeneic HSCT (allo-HSCT), day 7, and months 1, 3, 6 and 12 post-HSCT. Arterial hypertension was defined as a systolic blood pressure 140mmHg and/or a diastolic blood pressure 90 mmHg. Patients with history of arterial hypertension were excluded. Descriptive statistics were used to analyze patient's demographic data. Bivariate and multivariate analyses were performed to assess the association between clinical characteristics and arterial hypertension. Results: One hundred and seventy-one patients were included, with a median age of 45 years (range 18-71). Eighty-nine patients (52.1%) were male. One hundred and fifteen patients (67.3%) underwent auto-HSCT and 56 (32.7%) allo-HSCT. The most common indication for HSCT were lymphomas (39.8%), followed by leukemia (28.6%) and multiple myeloma (23.4%). Thirty-six patients (21.1%) developed arterial hypertension by the end of the first year of follow-up. Prevalence of hypertension at each time point was 2.3% on day 7 post-HSCT, 4.7%, 5.3%, 5.5% and 8.1% at 1, 3, 6 and 12 months respectively. Allo-HSCT (P<0.001), diagnosis of leukemia (P<0.001) or lymphoma (P<0.05), therapy with calcineurin inhibitors (P=0.004), prophylactic treatment for GvHD with mycophenolate (P<0.05) and acute GvHD (P<0.001) were significantly associated with the development of arterial hypertension. After performing multivariate regression analysis to identify arterial hypertension associated factors, patients with allo-HSCT were found to be 3 times more likely to develop arterial hypertension than patients with auto-HSCT (95% CI 1.85-8.60, P=0.000). Conclusions: Screening for arterial hypertension is warranted in HSCT survivors since it is a modifiable cardiovascular risk factor. Similar to previously reported findings, we found an association between post-HSCT arterial hypertension and allo-HSCT, use of calcineurin inhibitors and mycophenolate, and development of acute GvHD. Patients undergoing allo-HSCT are at increased risk of developing hypertension. Disclosures Sandoval-Sus: Seattle Genetics: Membership on an entity's Board of Directors or advisory committees.

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.

Abstract Objective: We assessed the impact of high-resolution genotypic results of human leukocyte antigen (HLA) for all major class I and II loci between donors and recipients in the outcome of unrelated hematopoietic stem cell transplantation (HSCT). Method: Between 1999 and 2005, high-resolution genotyping for HLA-A, -B, -C and -DRB1 was performed for 23 unrelated HSCT. All the patients were typed as HLA identical by serologic technique and then they were also typed HLA identical by high resolution technique. Unrelated bone marrow transplantation using DNA-based high resolution HLA compatibilities were considered in the analyses of clinical outcomes such as hematopoietic engraftment, acute GVHD, and survival. And then, we compared with patients who received related HSCT (same institute, same duration) and also unrelated HSCT data from IBMTR. Results: Median follow up duration was 9 months (1–51). Fifteen patients were male and 8 were female. Median age was 22 years (range 6–52). Median time from diagnosis to transplantation was 7 months (range 4–63). Eight patients of acute myeloid leukemia (AML), 6 of chronic myeloid leukemia (CML, 2 of 6 were in blast crisis), 4 of acute lymphoid leukemia (ALL), 3 of severe aplastic anemia and each case of juvenile myelomonocytic leukemia and myelodysplastic syndrome were enrolled. Median value of total nucleated cell and CD34 positive cell count was 3.51 (1.06–20.7) x 108/kg and 4.88 (1.33–46.9) x 106/kg, respectively. The conditioning regimen and prophylaxis for graft versus host disease (GVHD) were not different from conventional HSCT except one case of non-myeloablative transplantation. Median value of granulocytic (absolute granulocyte count > 500/mm3) and platelet (> 20,000/mm3) engraftment were D + 16, D + 17, respectively. Grade II acute GVHD developed in 4 patients (2 patients subsequently proceded to chronic GVHD). Treatment related mortality was 2 out of 23 patients (8.7%). Median value of overall survival duration was 30 months. For AML patients, 3-year survival rate was 72.9 %. Conclusions: Our survival data for unrelated HSCT based on high resolution genotyped HLA matching was superior to unrelated HSCT. Although the sample size is small, the survival data of AML patients (CR1 at transplant) was superior to the survivals of related HSCT, as well as that of unrelated HSCT. The findings were that transplantation using unrelated donors selected by high-resolution genotype identity improves the transplantation outcomes similar degree to the result of the related HSCT.

Abstract Abstract 3461 Expansion of CD3+ large granular lymphocytes (T-LGL) can be observed in situations such as viral infection, autoimmune disease, malignant neoplasm, and following allogeneic hematopoietic stem cell transplantation (HSCT). We sought to evaluate in patients treated with allogeneic HSCT incidence, characteristics, and clinical significance of persistent post-transplant T-LGL expansion. In this single center retrospective cohort study, we included all patients seen between January/08 and December/09 in our out-patient clinic for their regular follow-up. In patients with persistent lymphocytosis (>3 G/l for >3months) and an abnormal CD4/CD8 ratio, an extensive immunophenotyping was assessed; in case of an abnormal expansion of T-LGL cells a TCR gene rearrangement was performed. In 14 (7%) out of 215 evaluated patients a T-LGL expansion was diagnosed. Patients' characteristics with and without T-LGL expansion are summarized in Table 1. The median time between HSCT and diagnosis of lymphocytosis was 12 months (1-58). The median lymphocyte count was 4.24 G/l (3.0-26.5). The median duration of lymphocytosis was 29 (4-176) months. In 13/14 cases there was a CD3+/CD8+ immunophenotype, in 1 case was CD3+CD4+. In 5/14 patients a clonal TCR-gene rearrangement was observed. None of the patients presented neutropenia. Mild anemia was observed in 8/14 patients (57%), and thrombocytopenia in 2/14 patients; both changes were most probably not related with the T-LGL expansion. None of the patients had typical clinical signs of a T-LGL leukemia. In the univariate analysis acute GvHD and CMV reactivation were the only variables associated with T-LGL expansion, In the multivariate the relative risk (RR) of CMV reactivation was 5.063 (95%CI: 1.586–16.160; p=0.006) and the RR of acute GvHD grade 2–4 was 2.831 (95%CI: 0.831–9.648; p=0.096). Conclusion: we detected a T-LGL expansion in 7% of patients after HSCT. No symptoms or clinical signs related to T-LGL leukemia were observed. The T-LGL expansions, even when monoclonal, showed a chronic but indolent course. They have to be considered rather as an expression a chronic stimulation, triggered by causes such CMV reactivation or acute GvHD rather than as a malignant transformation. The question whether a T-LGL expansion plays a GvL role could not be answered in this study due to the small number of patients and the study design.

Abstract 839FN2 Many patients who require allogeneic hematopoietic stem cell transplantation (allo-HSCT) lack a human leukocyte antigen (HLA)-matched donor. Recently, we developed a new strategy named GIAC protocol for HLA-mismatched/haploidentical transplantation from family donors that combines granulocyte-colony stimulating factor (G-CSF) primed bone marrow (G-BM) and peripheral blood stem cells (PBSC) without in vitro T-cell depletion (TCD). For the past nine years, promising results for HLA-mismatched allo-HSCT without in vitro TCD have been achieved at our institute using this protocol. From May 2002 to December 2010, 820 patients, including 206 in high-risk group, underwent transplantation from haploidentical family donors. Eight-hundred and eleven patients (99%) achieved sustained, full donor chimerism. The incidence of grade 2–4 acute graft-versus-host disease (GVHD) was 42.9%, and that of grades 3 and 4 was 14.0% which was not associated with the extent of HLA disparity.Figure 1Cumulative incidence of acute GVHD grade 2–4 according to HLA disparity.Figure 1.
