Abstract
Haematopoietic stem cell transplantation is a mainstay of therapy for numerous malignant and nonmalignant diseases. Endothelial activation and dysfunction occur after stem cell transplantation, driven by various patient- and transplant-specific factors. This can manifest as one of the relatively uncommon endothelial injury syndromes, such as sinusoidal obstruction syndrome, transplant-associated thrombotic microangiopathy, idiopathic pneumonia syndrome, capillary leak syndrome, engraftment syndrome or posterior reversible encephalopathy syndrome. This review focuses on the pathogenesis, classification and diagnosis of these disorders, as well as provides guidance on risk mitigation and treatment.

Transplant Cell Ther 2022; 28:355.e1-355.e9. [PMID: 35405367 DOI: 10.1016/j.jtct.2022.03.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 12/20/2021] [Accepted: 03/30/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Hematopoietic stem cell transplantation (HSCT) is associated with severe medical complications and variable outcome depending on the recipient's disease stage and health condition. Biomarkers predicting outcome may have therapeutic relevance in pediatric cancer care. Insulin like growth factor 1 (IGF 1) is a mitogenic and anabolic peptide hormone that is expressed in almost all tissues. This hormone is the major growth factor in childhood. As IGF 1 is decreased in conditions that cause catabolic metabolism, it may reflect the degree of physical robustness of the patient and serve as predictive biomarker for transplant outcome. OBJECTIVES AND STUDY DESIGN We evaluated the impact of pre-transplant serum-IGF 1 on both survival and adverse events in 587 pediatric cancer patients, who underwent autologous or allogeneic HSCT between 1987 and 2014 at the University Children's Hospital Tübingen, Germany. Survival probabilities of the entire cohort and of defined subgroups according to pre-transplant serum-IGF-1 were estimated using the Kaplan-Meier method. RESULTS Mean pre-transplant IGF 1 (n = 498) was low: -1.67 SDS (SD, 1.54). Completeness of follow-up three and ten years post HSCT was 96 % and 83 %, respectively. The ten-year overall survival was 44.8 % (95 % confidence interval [CI], 40.6-48.9). With decreasing IGF-1 SDS, there was a significant increase of transplant-related mortality (p = 0.027), sinusoidal obstruction syndrome (quartiles 4 to 1: 3; 1; 12; 12%; p < 0.001) and thrombotic microangiopathy (quartiles 4 to 1: 0: 0: 2; 5%; p = 0.004). IGF 1 decile 1 showed a significantly poorer outcome (p=0.042) with lower median (12 versus 68 months) and ten-year overall survival (37 % versus 52 %) when compared to decile 2-10. CONCLUSIONS This retrospective study suggests pre-transplant serum-IGF 1 as a predictor of survival and selected vascular adverse events that may have diagnostic and therapeutic relevance in pediatric cancer care.

Abstract
Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is one of the most severe and life-threatening complications after hematopoietic stem cell transplantation (HSCT). Defibrotide (DF) is approved for adult and pediatric patients with VOD/SOS with renal or pulmonary dysfunction after HSCT in the United States, and for severe VOD/SOS post-HSCT in patients above 1 month of age in the European Union. Several studies have examined whether DF prophylaxis can reduce the incidence of VOD/SOS in high-risk patients. A total of 334 pediatric allogeneic HSCT were included in this study. All patients received DF at the dose of 25 mg/kg/d, from the first day of the conditioning regimen to the 30th day after transplantation for VOD/SOS prophylaxis. Seventeen patients (5.08%) developed VOD/SOS; 4 of these had moderate, while 13 had mild VOD/SOS. None of the patients were developed severe or very severe VOD/SOS. In conclusion, we showed that prophylactic intervention with DF lowered the incidence of VOD/SOS in high-risk pediatric patients.

Abstract
BACKGROUND Hepatic sinusoidal obstruction syndrome (SOS) is a serious complication of autologous stem cell transplant (ASCT) in children with historically high mortality rates. Defibrotide has shown proven benefit in its treatment and may have a modest role in prevention. We report our experience with SOS in children undergoing autologous transplant. METHODS Case records of 82 consecutive patients undergoing ASCT following high-dose chemotherapy between 2010 and 2017 were reviewed. Defibrotide was used for treatment of all with SOS and prophylactically in patients receiving busulfan-based conditioning until 2014. RESULTS Fourteen of the 82 children (17%) were diagnosed with SOS. The incidence was higher in those receiving busulfan-based conditioning (13/42 vs 1/40, P = 0.008). Mean (±SD) time to diagnosis of SOS was 19 (±5.6) days following stem cell rescue. Bilirubin levels and ultrasound were normal in 7/14 and 3/14 patients. Coagulopathy was noted in 10/14; one child developed multiorgan involvement. Nine children had mild SOS, whereas two and three had moderate and severe SOS, respectively. Intensive care was required for four of five non-mild cases. Patients with SOS had significantly delayed platelet recovery, higher transfusion requirement, and longer hospital stay. Unavailability of defibrotide prophylaxis for 17/42 receiving busulfan did not change the incidence of SOS (7/25 with defibrotide vs 6 /17 without defibrotide, P = 0.74). There was no significant difference in the severity of SOS between these groups. CONCLUSION Hepatic SOS was more commonly seen in children receiving busulfan-based conditioning. Stopping the use of prophylactic defibrotide did not increase incidence or severity of SOS. Overall outcome was excellent with supportive care and timely treatment with defibrotide.

Abstract
Hepatic veno-occlusive disease (VOD) is a serious systemic endothelial complication after stem cell transplantation. Defibrotide is under investigation as a prophylactic agent for VOD; however, high costs limit its utility. We evaluated the prophylactic efficacy of a low-dose defibrotide regimen for VOD. We retrospectively enrolled 147 paediatric patients who underwent autologous haematopoietic stem cell transplantation (HSCT; 69 with defibrotide prophylaxis and 78 historical controls) at the Yonsei Cancer Center in Seoul, Korea, between March 2013 and Feb 2020. Low-dose defibrotide (12.5 mg/kg/day) was administered from D-3 to D+10 after HSCT. The most common diagnosis in the cohort was brain tumour (N = 86). VOD developed in 10 (12.8%) and 3 (4.3%) patients in the control and prophylaxis groups, respectively (P = 0.071). In the second HSCT group, VOD incidence was significantly lower in the prophylaxis group [2.9% (1/35)] than in the control group (28.6%, 6/21, P = 0.005). VOD severity was significantly higher in the control group than in the prophylaxis group (P = 0.006). Three VOD-related mortalities occurred in the control group, whereas no VOD-related mortality occurred in the prophylaxis group. In conclusion, low-dose defibrotide prophylaxis is a promising and economical strategy for preventing VOD, especially in second-round HSCT.

Abstract
Objectives Determine the effectiveness and cost of defibrotide in patients with severe hepatic sinusoidal obstruction syndrome following haematopoietic stem cell transplantation in a tertiary hospital. Methods A retrospective observational study. Adults or children treated with defibrotide at a mean dose of 6.8 mg/kg every 6 hours, until the total bilirubin levels are normalised, were included. Main endpoint was complete response, defined as normalised total serum bilirubin levels and resolution of multiple organ failure. Secondary endpoints were survival by 100 days post-transplant, influence of risks factors in effectiveness and cost of treatment. Results 51 patients (36 adults and 15 children) received defibrotide; median dose of defibrotide administered was 25.19 mg/kg/day (10.0-100.3). Complete response was achieved in 19 (37.3%) patients. By 100 days post-transplant complete response was achieved in 18 (35.3%) patients and the survival rate was 29 (56.9%) patients. There were no significant differences in effectiveness between adults versus paediatrics and between patients who presented risk factors. The mean cost of treatment per patient was €32 916, mean costs in adults was €104 292 and €17 394 in children. Conclusion Regarding the results of our study, it is convenient to identify the patients who will be able to benefit from this treatment according to clinical conditions, medical history and prognosis. Given the great economic impact of defibrotide, we consider that more cost-effectiveness studies are required. Trial registration number EPA-OD, number LBM-DEF-2016-01.

Abstract
Busulphan (Bu) is a myeloablative drug used for conditioning prior to hematopoietic stem cell transplantation. Bu is predominantly metabolized through glutathione conjugation, a reaction that consumes the hepatic glutathione. N-acetyl-l-cysteine (NAC) is a glutathione precursor used in the treatment of acetaminophen hepatotoxicity. NAC does not interfere with the busulphan myeloablative effect. We investigated the effect of NAC concomitant treatment during busulphan conditioning on the liver enzymes as well as the clinical outcome. Prophylactic NAC treatment was given to 54 patients upon the start of busulphan conditioning. These patients were compared with 54 historical matched controls who did not receive NAC treatment. In patients treated with NAC, aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP) were significantly (P < 0.05) decreased after conditioning compared to their start values. Within the NAC-group, liver enzymes were normalized in those patients (30%) who had significantly high start values. No significant decrease in enzyme levels was observed in the control group. Furthermore, NAC affected neither Bu kinetics nor clinical outcome (sinusoidal obstruction syndrome incidence, graft-versus-host disease and/or graft failure). In conclusion: NAC is a potential prophylactic treatment for hepatotoxicity during busulphan conditioning. NAC therapy did not alter busulphan kinetics or affect clinical outcome.

Abstract
OBJECTIVE To review the efficacy and safety of defibrotide as well as its pharmacology, mechanism of action, pharmacokinetics (PK), drug-drug interactions, dosing, cost considerations, and place in therapy. DATA SOURCES A PubMed search was performed through August 2017 using the terms defibrotide, oligonucleotide, hepatic veno-occlusive disease (VOD), sinusoidal obstruction syndrome (SOS), and hematopoietic cell transplantation (HCT). Other data sources were from references of identified studies, review articles, and conference abstracts plus manufacturer product labeling and website, the Food and Drug Administration website, and clinicaltrials.gov. STUDY SELECTION AND DATA EXTRACTION English-language trials that examined defibrotide's pharmacodynamics, mechanism, PK, efficacy, safety, dosing, and cost-effectiveness were included. DATA SYNTHESIS Trials have confirmed the safety and efficacy of defibrotide for treatment of VOD/SOS in adult and pediatric HCT patients, with complete response rates and day +100 overall survival rates ranging from 25.5% to 76% and 35% to 64%, respectively. The British Committee for Standards in Haematology/British Society for Blood and Marrow Transplantation Guidelines recommend defibrotide prophylaxis in pediatric and adult HCT patients with risk factors for VOD/SOS; however, its prophylactic use in the United States is controversial. Although there are efficacy data to support this strategy, cost-effectiveness data have not shown it to be cost-effective. Defibrotide has manageable toxicities, with low rates of grade 3 to 4 adverse effects. CONCLUSIONS Defibrotide is the first medication approved in the United States for the treatment of adults and children with hepatic VOD/SOS, with renal or pulmonary dysfunction following HCT. Data evaluating defibrotide for VOD/SOS prevention are conflicting and have not shown cost-effectiveness.
