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.

e19002 Background: The presence of measurable residual disease (MRD) preceding hematopoietic stem cell transplantation (HSCT) in acute myeloid leukemia (AML) is increasingly recognized as a risk factor for leukemic relapse and decreased survival. Over many years, attempts have been looking at developing tools to detect MRD; this includes multiparametric flow cytometry, quantitative polymerase chain reaction, and most recently, next-generation sequencing (NGS). NGS offers higher sensitivity and detection rate of disease-related gene mutations, thereby potentially improving disease outcomes. Our study sought to review the scientific literature that included NGS‐detected molecular MRD in patients with AML who underwent bone marrow transplantation. Methods: We performed a systematic search using PubMed, Google Scholar, EMBASE, and SCOPUS up until October 2020. Inclusion criteria included articles that reported the association between pre-HSCT MRD detected by NGS and post HSCT outcome in patients with AML. We extracted hazard ratios for the cumulative incidence of relapse (CIR), overall survival (OS) and leukemia free survival (LFS). A random-effect model was utilized to calculate the hazard ratio (HR) with a 95% confidence interval (CI). Results: Six studies met our inclusion criteria. Our meta-analysis showed that the detection of pre-transplant MRD by NGS was associated with increased risk of cumulative incidence of relapse (hazard ratio=2.5, CI= 1.6-3.9, with p-value <0.001) and decreased overall survival (hazard ratio=1.6, CI= 1.6-2.3, p-value 0.005). LFS was significantly higher in those who had negative MRD detection by NGS before transplantation (HR=1.9, CI= 1.3-2.8 with p-value 0.001). These results were independent of the cytogenetic risk of conditioning intensity. There was heterogeneity between our studies (I2 = 53%, 52%, and 59% for CIR, OS, and LFS, respectively). Conclusions: The application of NGS to detect MRD is a strong predictor of outcome in patients with AML who are undergoing hematopoietic stem cell transplantation. NGS-detected MRD positive status prior to HSCT is indicative of a higher risk of relapse and decreased overall survival in this meta-analysis. Despite the limitations in our study, it demonstrates the value of MRD detection by NGS in HSCT recipients.
