Incidence of acute kidney disease after receiving hematopoietic stem cell transplantation: a single-center retrospective study.

ABSTRACT: Background:Previous reports have shown that acute kidney injury (AKI) is common after hematopoietic stem cell transplantation (HSCT), which is a crucial treatment for patients with hematological disorders. AKI could increase mortality and induce adverse effects including the development of chronic kidney disease. The incidence of AKI in association with HSCT reportedly varies significantly because several definitions of AKI have been adopted. Acute kidney disease (AKD) is a new concept that can clinically define both AKI and persistent decreases in glomerular filtration rate (GFR) state. We conducted a retrospective cohort study to determine the incidence of AKD after HSCT. Methods:This study included 108 patients aged between 16 and 70 years undergoing HSCT. In this study, AKD included clinical condition of AKI or subacute decreases in GFR. AKI was defined according to the Kidney Disease: Improving Global Outcomes guidelines based on serum creatinine. However, urine output data were not included to define AKI because the database lacked some of these data. Comparisons were made between groups using the Mann-Whitney U test. Results:Acute kidney disease occurred in 17 patients (15.7%). There were significant differences between the AKD and non-AKD with respect to ABO-incompatible HSCT (p = 0.001) and incidence of acute graft versus host disease (GVHD) after HSCT (p < 0.001). The 100-day overall survival of patients with AKD and without AKD after HSCT was 70.6% and 79.8%, respectively (p = 0.409). Discussion:ABO-incompatible HSCT and acute GVHD after HSCT were risk factors for the incidence of AKD. However, we could not find a significant association between AKD after HSCT and mortality.

Project description:BackgroundBronchiolitis obliterans (BO) is one of the most common late non-infectious pulmonary complications after hematopoietic stem cell transplantation (HSCT). Lung transplantation (LT) is the only cure for patients with end-stage BO, but the overall efficacy is rarely reported. Our study aims to conclude and elucidate the clinical experience of our single center and provide a reference for the current selection of treatment.MethodsWe retrospectively analyzed the medical records of six patients with post-HSCT BO who received LT in our center from 2015 to 2019. The collected information included demographic data, surgery-related conditions, and postoperative follow-up data, which covered blood tests, infection status assessment, lung function assessment, anesthesia assessment, function assessment of other organs and so on. All patients were regularly followed up after discharge, which in the first year, was performed every 3 months. Over the next 2 years, patients were assessed every 6 months, and after 3 years, the frequency was once annually.ResultsThe mean age of patients at LT time was 28±13 years, with an interval of 72±48 months from HSCT. All patients developed hypercapnia with an average carbon dioxide partial pressure (pCO2) of 71.1±20.8 mmHg. Preoperative pulmonary function tests showed the mean actual forced expiratory volume in 1 second (FEV1) was 16.7%±5.9% of the predicted value in four patients. After assessment, four patients adopted sequential bilateral LT and two adopted right-sided LT. Due to hemodynamic instability, five patients adopted intraoperative assistance of extracorporeal membrane oxygenation (ECMO). One patient died of septic shock 9 days after surgery, and the other five survived healthy for 53±23 months. The actual value of FEV1 at 3 months postoperatively accounted for 57.9%±15.3% of the predicted value. No patients had recurrence of BO.ConclusionsLT may be a treatment worthy of consideration in patients with post-HSCT end-stage BO because it can improve lung function, quality of life and prolong survival of these selected patients.

Project description:BackgroundMucosal-associated invariant T (MAIT) cells are innate-like T cells, some studies have reported that the number of circulating MAIT cells reduced in patients with acute graft-versus-host-disease (aGVHD) development. However, the role of donor MAIT cells on aGVHD development and subsequent functional change still remain unclear.MethodsThe study recruited 86 patients with hematological malignancies who underwent allogeneic hematopoietic cell transplantation (HCT) from May 1, 2018 to June 30, 2019. MAIT cells, their subset, and cytokine levels were measured by flow cytometry. Gray's test was used to assess the impact of graft MAIT cell proportion and number on aGVHD incidence. The Cox proportional hazard model was used in the multivariate analysis. The comparison for continuous variables was assessed using Mann-Whitney analysis. RNA-sequencing was performed to investigate the possible molecular pathway changes.ResultsOur study showed that the proportion of MAIT cells in grafts was not different from normal controls, but the CD4/8 subsets were altered. Taking the median of the proportion and number of MAIT cells in the graft as the threshold, the results showed that the incidence of grade B-D aGVHD in patients with MAIT cell proportion ≥ 3.03% was significantly higher than that in patients with MAIT cell proportion < 3.03% (56.3%, 95% CI 37.1-71.2 versus 23.1%, 95% CI 13.8-46.2; P = 0.038).The number of MAIT cells in the graft was not associated with aGVHD development (P = 0.173), however, when the graft contained more CD4 positive, CD8 positive, and CD4/CD8 double-positive MAIT cells, the incidence of aGVHD was significantly increased (P = 0.019, P = 0.035 and P = 0.027, respectively). Besides, reduced frequencies and counts of circulating MAIT cells were observed in patients with aGVHD when compared to patients without aGVHD, accompanied by enhanced production of Tumor necrosis factor-α, Interferon-γ and upregulated programmed death-1, CXC Chemokine Receptor-6 (CXCR6) and CD38 expression. Gene set enrichment analysis of MAIT cell RNA-seq data showed interferon-α response pathway upregulated in aGVHD patients when compared with patients without aGVHD and healthy controls.ConclusionsOur study shows that MAIT cells in grafts and peripheral blood are both closely related to the aGVHD development post allogeneic HCT. Interferon-α response pathway perhaps is a critical regulation mechanism for the MAIT cell involvement in aGVHD development.

Project description:Background and objectivesAKI is a major complication of allogeneic hematopoietic stem cell transplantation, increasing risk of nonrelapse mortality. AKI etiology is often ambiguous due to heterogeneity of conditioning/graft versus host disease regimens. To date, graft versus host disease and calcineurin inhibitor effects on AKI are not well defined. We aimed to describe AKI and assess pre-/post-hematopoietic transplant risk factors in a large recent cohort.Design, setting, participants, & measurementsWe performed a single-center, retrospective study of 616 allogeneic hematopoietic cell transplant recipients from 2014 to 2017. We defined AKI and CKD based on Kidney Disease Improving Global Outcomes (KDIGO) criteria and estimated GFR using the Chronic Kidney Disease Epidemiology Collaboration equation. We assessed AKI pre-/post-hematopoietic transplant risk factors using cause-specific Cox regression and association of AKI with CKD outcomes using chi-squared test. AKI was treated as a time-dependent variable in relation to nonrelapse mortality.ResultsIncidence of AKI by day 100 was 64%. Exposure to tacrolimus and other nephrotoxins conferred a higher risk of AKI, but tacrolimus levels were not associated with severity. Reduced-intensity conditioning carried higher AKI risk compared with myeloablative conditioning. Most stage 3 AKIs were due to ischemic acute tubular necrosis and calcineurin inhibitor nephrotoxicity. KRT was initiated in 21 out of 616 patients (3%); of these 21 patients, nine (43%) recovered and five (24%) survived to hospital discharge. T cell-depleted transplants, higher baseline serum albumin, and non-Hispanic ethnicity were associated with lower risk of AKI. CKD developed in 21% (73 of 345) of patients after 12 months. Nonrelapse mortality was higher in those with AKI (hazard ratio, 2.77; 95% confidence interval, 1.8 to 4.27).ConclusionsAKI post-hematopoietic cell transplant remains a major concern. Risk of AKI was higher with exposure to calcineurin inhibitors. T cell-depleted hematopoietic cell transplants and higher serum albumin had lower risk of AKI. Of the patients requiring KRT, 43% recovered kidney function.PodcastThis article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2021_09_07_CJN19801220.mp3.

Project description:Viral reactivation occurs frequently in the context of immunodeficiency and immunosuppression after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and can cause severe complications. The aim of this single-center retrospective analysis was to characterize viral infections in the first year after HSCT, to investigate risk factors and to study the impact of viral infections on transplantation outcome. This will facilitate the identification of at-risk patients and the development of new preventive strategies. 107 pediatric allo-HSCT from January 2005 through December 2015 were analyzed for infections with Epstein-Barr virus (EBV), cytomegalovirus (CMV), human herpesvirus 6 (HHV-6), adenovirus (ADV), herpes simplex virus (HSV) and varicella zoster virus (VZV). Viral infections were detected after 68.2% of transplantations. The viruses most commonly encountered were HHV-6 (36/107) and EBV (30/107). Severe viral disease was rare (7/107) and none of the patients died as result of viral reactivation. Important risk factors for viral infections were higher age at HSCT, donor type and occurrence of acute graft-versus-host disease (aGvHD). Especially for EBV, transplant from an unrelated donor and in-vivo T-cell depletion (TCD) had a significant effect on infection rates, whereas for CMV the strongest effect was seen by donor and recipient serostatus with recipient seropositivity most predictive for reactivation. The occurrence of severe aGvHD was associated with EBV and ADV infections. For HSV, the recipient serostatus was identified as prognostic factor for HSV infections, while we found higher age at time of HSCT as risk factor for VZV infections. The overall survival of patients with or without viral infections did not differ significantly. Interestingly, when looking at the 85 patients in our cohort who had received an HSCT for a malignant disease, a tendency towards lower relapse rates was seen in patients affected by viral infections (HR 0.51, 95% CI 0.25 - 1.06, p = 0.072). Viral reactivations are common after pediatric allo-HSCT, though severe complications were rare in our collective. Determining risk factors for viral reactivations may help to identify patients in need of intensified monitoring and to individualize preventive strategies.
