Abstract
Antisense oligonucleotides (ASOs) are short, synthetic, single-stranded deoxynucleotide sequences composed of phosphate backbone-connected sugar rings. Designing of those strands is based on Watson-Crick hydrogen bonding mechanism. Thanks to rapidly advancing medicine and technology, evolving of the gene therapy area and ASO approaches gain attention. Considering the genetic basis of diseases, it is promising that gene therapy approaches offer more specific and effective options compared to conventional treatments. The objective of this review is to explain the mechanism of ASOs and discuss the characteristics and safety profiles of therapeutic agents in this field. Pharmacovigilance for gene therapy products is complex, requiring accurate assessment of benefit-risk balance and evaluation of adverse effects.

Endothelial cell activation mediated by cold ischemia-released mitochondria is partially inhibited by defibrotide and impacts on early allograft function following liver transplantation. Biomed Pharmacother 2023; 167:115529.

Abstract
DAMPs (danger-associated molecular patterns) are self-molecules of the organism that appear after damage. The endothelium plays several roles in organ rejection, such as presenting alloantigens to T cells and contributing to the development of inflammation and thrombosis. This study aimed to assess whether DAMPs present in the organ preservation solution (OPS) after cold ischemic storage (CIS) contribute to exacerbating the endothelial response to an inflammatory challenge and whether defibrotide treatment could counteract this effect. The activation of cultured human umbilical vein endothelial cells (HUVECs) was analyzed after challenging with end-ischemic OPS (eiOPS) obtained after CIS. Additionally, transwell assays were performed to study the ability of eiOPS to attract lymphocytes across the endothelium. The study revealed that eiOPS upregulated the expression of MCP-1 and IL-6 in HUVECs. Moreover, eiOPS increased the membrane expression of ICAM-1and HLA-DR, which facilitated leukocyte migration toward a chemokine gradient. Furthermore, eiOPS demonstrated its chemoattractant ability. This activation was mediated by free mitochondria. Defibrotide was found to partially inhibit the eiOPS-mediated activation. Moreover, the eiOPS-mediated activation of endothelial cells (ECs) correlated with early allograft dysfunction in liver transplant patients. Our finding provide support for the hypothesis that mitochondria released during cold ischemia could trigger EC activation, leading to complications in graft outcomes. Therefore, the analysis and quantification of free mitochondria in the eiOPS samples obtained after CIS could provide a predictive value for monitoring the progression of transplantation. Moreover, defibrotide emerges as a promising therapeutic agent to mitigate the damage induced by ischemia in donated organs.

Abstract
Background In adults with medically refractory sinusoidal obstruction syndrome (SOS), a transjugular intrahepatic portosystemic shunt (TIPS) has been used successfully to improve portal hypertension and symptoms such as ascites. There is limited data on the use of TIPS for SOS in pediatric patients. Methods The index case was reviewed retrospectively. PubMed and Medline databases were searched to identify other cases. Results A 4-year-old male with high-risk neuroblastoma, developed SOS after tandem autologous stem cell transplant. He was medically managed with defibrotide, diuretics, and peritoneal drainage, but, due to refractoriness, he underwent TIPS day +54 following bone marrow transplant. Hepatic venous pressure gradient improved from 17 to 8 mm Hg following TIPS placement with significant improvement in the patient's clinical status and ascites. However, 15 months later, his shunt remained patent, and he remains clinically well with stable liver enzymes. A literature review identified 13 pediatric cases of TIPS for SOS due to varied causes. TIPS caused a median hepatic venous pressure gradient of 9 mmHg (range, 2-38 mm Hg). The mortality following the procedure was 15%, with 2 cases who died at 2- and 11-days post-TIPS. At the time of the last follow-up (range 8-25 months), 5 patients were alive, and 8 were lost to follow-up. Conclusion We present here a pediatric case of SOS due to stem cell transplant treated successfully with TIPS with a review of the literature. A timely, individualized application of TIPS can be effective in treating children with medication-refractory SOS.

Incidence of sinusoidal obstruction syndrome/veno-occlusive disease and treatment with defibrotide in allogeneic transplant: A multicentre Australasian registry study. Transplant Cell Ther 2023:S2666-6367(23)01173-9. [PMID: 36934993 DOI: 10.1016/j.jtct.2023.03.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 03/03/2023] [Accepted: 03/13/2023] [Indexed: 03/19/2023]
Abstract
BACKGROUND Sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) is an established complication in patients undergoing allogeneic haemopoietic stem cell transplantation. Defibrotide is an effective and safe pharmacological option for treating diagnosed SOS/VOD. OBJECTIVE By exploring data provided to the Australasian Bone Marrow Transplant Recipient Registry (ABMTRR) by centres from Australia and New Zealand, this study aimed to describe the incidence of SOS/VOD and patterns of defibrotide use from 2016 to 2020. STUDY DESIGN Patients who underwent allogeneic HSCT between 2016 and 2020 were identified from the ABMTRR. Data was extracted for a total of 3346 patients, 2692 from adult centres and 654 from paediatric centres, with a median follow up of 21.5 months and 33.3 months respectively. Descriptive statistics were used to describe the patient population, including the incidence of SOS/VOD and defibrotide use. Comparisons were made between patients not experiencing SOS/VOD, and those with the diagnosis, divided into defibrotide and no-defibrotide cohorts. Associations with overall survival and day 100 survival with variables such as gender, age, disease at transplant, source of stem cells, conditioning agents, SOS/VOD diagnosis and use of defibrotide were determined. RESULTS The reported incidence of SOS/VOD was 4.1% in adult centres and 11.5% in paediatric centres. Defibrotide was administered to 74.8% of adult patients with SOS/VOD and 97.3% of paediatric patients. Significant variability of use, dose and duration of defibrotide was seen across the adult centres. Day 100 survival rate and median overall survival (OS) for patients managed with defibrotide was 51.8% and 103 days respectively for adult patients, and 90.4% and not reached for paediatric patients. In adults, older age at transplant, an HLA matched donor who was a non-sibling relative, and a diagnosis of SOS/VOD treated with defibrotide, were all associated with reduced OS. In paediatrics, the patient and transplant characteristics that were associated with a reduced OS were a diagnosis of SOS/VOD and donor relation as 2 or more HLA mismatched relative. CONCLUSION A collaborative approach across Australasia to diagnose and manage SOS/VOD, in particular with respect to consistent defibrotide use, is recommended.

Abstract
BACKGROUND Hepatic sinusoidal obstruction syndrome (HSOS) is a rare complication in solid organ transplant recipients, especially in liver transplantation recipients. However, the consequences of HSOS occurrence are pernicious, which could result in severe liver or renal failure, and even death. In addition to previously reported azathioprine and acute rejection, tacrolimus is also considered as one predisposing factor to induce HSOS after liver transplantation, although the underlying mechanism remains unclear.
CASE SUMMARY In this study, we reported three cases of tacrolimus-related HSOS after liver transplantation. The diagnosis of HSOS was firstly based on the typical symptoms including ascites, painful hepatomegaly and jaundice. Furthermore, the features of patchy enhancement on portal vein and delayed phase of abdominal enhanced computed tomography were suspected of HSOS and ultimately confirmed by liver biopsy and histological examination in two patients. A significant decrease in ascites and remission of clinical symptoms of abdominal distention and pain were observed after withdrawal of tacrolimus.
CONCLUSION Tacrolimus-induced HSOS is a scarce but severe complication after liver transplantation. It lacks specific symptoms and diagnostic criteria. Timely diagnosis of HSOS is based on clinical symptoms, radiological and histological examinations. Discontinuation of tacrolimus is the only effective treatment. Transplantation physicians should be aware of this rare complication potentially induced by tacrolimus.

Abstract
ABSTRACT Pediatric acute liver failure (PALF) is a rare, rapidly progressive clinical syndrome with significant morbidity and mortality. The phenotype of PALF manifests as abrupt onset liver dysfunction, which can be brought via disparate etiology. Management is reliant upon intensive clinical care and support, often provided by the collaborative efforts of hepatologists, critical care specialists, and liver transplant surgeons. The construction of an age-based diagnostic approach, the identification of a potential underlying cause, and the prompt implementation of appropriate therapy can be lifesaving; however, the dynamic and rapidly progressive nature of PALF also demands that diagnostic inquiries be paired with monitoring strategies for the recognition and treatment of common complications of PALF. Although liver transplantation can provide a potential life-saving therapeutic option, the ability to confidently determine the certainness that liver transplant is needed for an individual child has been hampered by a lack of adequately tested clinical decision support tools and accurate predictive models. Given the accelerated progress in understanding PALF, we will provide clinical guidance to pediatric gastroenterologists and other pediatric providers caring for children with PALF by presenting the most recent advances in diagnosis, management, pathophysiology, and associated outcomes.

Abstract
Hematopoietic stem cell transplantation-associated thrombotic microangiopathy (HSCT-TMA) is a life-threatening syndrome that occurs in adult and pediatric patients after hematopoietic stem cell transplantation. Nonspecific symptoms, heterogeneity within study populations, and variability among current diagnostic criteria contribute to misdiagnosis and underdiagnosis of this syndrome. Hematopoietic stem cell transplantation and associated risk factors precipitate endothelial injury, leading to HSCT-TMA and other endothelial injury syndromes such as hepatic veno-occlusive disease/sinusoidal obstruction syndrome, idiopathic pneumonia syndrome, diffuse alveolar hemorrhage, capillary leak syndrome, and graft-versus-host disease. Endothelial injury can trigger activation of the complement system, promoting inflammation and the development of endothelial injury syndromes, ultimately leading to organ damage and failure. In particular, the lectin pathway of complement is activated by damage-associated molecular patterns (DAMPs) on the surface of injured endothelial cells. Pattern-recognition molecules such as mannose-binding lectin (MBL), collectins, and ficolins—collectively termed lectins—bind to DAMPs on injured host cells, forming activation complexes with MBL-associated serine proteases 1, 2, and 3 (MASP-1, MASP-2, and MASP-3). Activation of the lectin pathway may also trigger the coagulation cascade via MASP-2 cleavage of prothrombin to thrombin. Together, activation of complement and the coagulation cascade lead to a procoagulant state that may result in development of HSCT-TMA. Several complement inhibitors targeting various complement pathways are in clinical trials for the treatment of HSCT-TMA. In this article, we review the role of the complement system in HSCT-TMA pathogenesis, with a focus on the lectin pathway.

Abstract
Allogeneic hematopoietic cell transplantation (alloHCT) is the standard of care for many diseases. However, survivors often present with serious complications resulting from acute and chronic toxicities and it is crucial to increase consciousness from treating physicians. We performed a comprehensive review of the literature and critically examined recent available data, mostly using the PubMed and Medline search engines for original articles published over the last decade. Better understanding of many alloHCT-related disorders has shown that endothelial injury and vascular damage plays a critical role. The most widely studied endothelial injury syndromes (EIS) are veno-occlusive disease/sinusoidal obstruction syndrome (SOS/VOD), graft-versus-host-disease (GVHD), and transplant-associated thrombotic microangiopathy (TA-TMA). TA-TMA, frequently underdiagnosed, needs to be clarified using certain criteria and, as a life-threatening condition, requires immediate and intensive treatment. The first-in-class complement inhibitor eculizumab has significantly improved outcomes in both the pediatric and adult population. Cardiovascular (CV) events are the second major cause of morbidity and mortality of alloHCT survivors, after GVHD. Long-term monitoring and management of CV risk is expected to also incorporate patient stratification with CV risk prediction models, early markers of vascular dysfunction or procoagulant activity, subclinical target organ damage, arterial stiffness, and subclinical atherosclerosis.

Abstract
BACKGROUND In patients with acute liver injury caused by hepatic veno-occlusive disease (HVOD), molecular adsorbent recirculation system (MARS) may be used to improve liver function in conjunction with transjugular intrahepatic portosystemic shunt (TIPS) to reduce portal hypertension. METHODS Twelve patients were admitted to our hospital following treatment for HVOD for 10 to 21 days at other hospitals. All patients were treated with a combination of MARS and TIPS, and they were evaluated clinically including liver function tests. RESULTS After the initial treatment with MARS, liver function improved significantly in all patients. TIPS placement decreased the hepatic venous pressure gradient (HVPG) to 10.17 ± 2.26 mmHg from a pre-TIPS HVPG of 23.58 ± 9.43 mmHg. The outcomes of combination treatment with MARS and TIPS in 12 patients with HVOD were as follows: 1) improvement of various clinical and biological parameters leading to full recovery in 1 year in 6 patients; 2) full recovery following liver transplantation for acute liver failure in three patients; and 3) three patients died due to hepatic failure after TIPS placement. CONCLUSION The combination of MARS and TIPS creation is promising as a potential treatment for acute HVOD, and it showed an improvement in overall survival.

Xiao J, Tu J, Zhang H, Zhang F, Zhang W, Xu H, Yin Q, Yang J, Han H, Wang Y, Zhang B, Peng C, Zou X, Zhang M, Zhuge Y. Risk factors of poor prognosis in patients with pyrrolidine alkaloid-induced hepatic sinusoidal obstruction syndrome after transjugular intrahepatic portosystemic shunt. Hepatol Int 2021; 15:720-729. [PMID: 33507485 DOI: 10.1007/s12072-020-10126-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Accepted: 12/19/2020] [Indexed: 11/09/2022]
Abstract
AIMS Transjugular intrahepatic portosystemic shunt (TIPS) is an effective method in treating patients with severe hepatic sinusoidal obstruction syndrome induced by pyrrolidine alkaloids (PA-HSOS). However, some patients still have poor postoperative prognosis. So, we aim to evaluate the predictors associated with poor outcomes in PA-HSOS patients receiving TIPS. METHODS Patients who were diagnosed as PA-HSOS and received TIPS in our hospital between January 2013 and April 2019 were reviewed retrospectively. Baseline information and clinical data were collected. The hazard ratios (HRs) of factors associated with poor prognosis were analyzed by Cox proportional hazard analysis. The Kaplan-Meier method was used to analyze and compare the cumulative incidence of the poor results and survival rate of patients. RESULTS During a median of 19.25-month follow-up, death occurred in 17 patients. We found that prothrombin time at baseline with an adjusted HR 1.110 (95% confidence interval 1.014-1.216, p = 0.024) and serum total bilirubin of 9 mg/dl 5 days after TIPS with an adjusted HR 1.114 (95% confidence interval 1.042-1.190, p = 0.001) were independent risk factors for death. The 1-year and 5-year survival rate were 86.2% and 82.1%, respectively. The 1-year survival rate in patients with prothrombin time > 17.85 s at baseline and serum total bilirubin > 9 mg/dl at 5 days after TIPS was significantly lower than that of patients below the corresponding threshold, respectively. CONCLUSIONS Prolonged prothrombin time at baseline and increased serum total bilirubin levels 5 days after TIPS are independent risk factors for predicting death after TIPS treatment in PA-HSOS patients.

Targeted-dose of busulfan: Higher risk of sinusoidal obstructive syndrome observed with systemic exposure dose above 5000 µMol⸱min. A historically controlled clinical trial. Hematol Oncol 2020; 38:773-781. [PMID: 32779746 DOI: 10.1002/hon.2789] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2019] [Revised: 07/22/2020] [Accepted: 08/07/2020] [Indexed: 11/12/2022]
Abstract
Busulfan is given in the conditioning regimens preceding hematopoietic stem cell transplantation (HSCT), and plasma levels can be monitored. A targeted, individualized systemic exposure (SE) dose can be achieved by calculating the area under the plasma concentration versus time curve (AUC). The objective of this study was to determine a cutoff value for safety for the AUC for busulfan plasma levels in patients undergoing HSCT. A total of 149 consecutive HSCT patients were studied. After an oral test dose of busulfan, we set target doses of 4000, 5000, or 6000 µMol⸱min/day, and analyzed the AUC of oral or intravenous Bu. These patients were compared with 53 historical control subjects who had received myeloablative conditioning regimen without busulfan pharmacokinetic monitoring. Using a test dose and the administration route had no impact on the sinusoidal obstructive syndrome (SOS) incidence, transplant-related mortality or 1-year overall survival. However, patients receiving busulfan at doses set up at AUC > 5000 had an increased risk to develop SOS after HSCT (hazard ratio 3.39, p = 0.034, 95% CI 1.09-10.52). Adjusting the busulfan dose according to SE levels target dose during conditioning is associated with lower rates of oral severe mucositis and SOS. A cutoff of 5000 µMol⸱min is safe and does not impair survival.

Abstract
Hematologic diseases include a broad range of acquired and congenital disorders, many of which affect plasma proteins that control hemostasis and immune responses. Therapeutic interventions for these disorders include transfusion of plasma, cryoprecipitate, immunoglobulins, or convalescent plasma-containing therapeutic antibodies from patients recovering from infectious diseases, as well as concentrated pro- or anticoagulant factors. This review will focus on recent advances in the uses of plasma and its derivatives for patients with acquired and congenital hematologic disorders.

Abstract
Background Hepatic venous-occlusive disease is blockage of microscopic veins in the liver causing 20–50% mortality. Ingestion of pyrrolizidine alkaloid plant, radiation therapy, and post-bone-marrow-transplant reactions are the commonest causes. In Ethiopia, a venous-occlusive disease outbreak was identified in 2002 in Tahtay Koraro district, Tigray. Suspected due to ingestion of the toxic pyrrolizidine alkaloid plant Ageratum conyzoids, found throughout the district. We aimed to describe the surveillance data of venous-occlusive disease from September 2006 to August 2016 in Tahtay koraro district, Ethiopia, 2017. Methodology We defined a possible Hepatic venous-occlusive disease case as any patient with abdominal pain for at least 2 weeks, abdominal distention, and hepato-splenomegaly during September 2006-August 2016. We reviewed previous district line lists, weekly reports, and clinical records to identify and describe cases. Agricultural interventions were obtained from the agricultural offices of the district. Result We identified 179 possible cases with 83 deaths with a case-fatality rate of 46.3%. Among cases, 110 (61.5%) were males and 113 (63%) were >15 years. In total, 164 (91.6%) cases were from one village (Kelakil). The pick number of cases of VOD in this village was during 2008/09 which was 1076. The highest incidence (86/100,000) occurred in 2008. During the study period, 2,746 years of potential life were lost due to Hepatic venous-occlusive disease. Mechanical removal of the Ageratum started in 2011. Conclusion Hepatic venous-occlusive disease was an ongoing problem in Tahtay Koraro; However, the problem has largely been alleviated by displacing people from the affected area and removing the causative weed. More research is needed to understand why Kelakil village was more affected despite the widespread presence of the weed. Chemical and mechanical removal of the Ageratum could strengthen intervention activities.

Preclinical evaluation of local prolonged release of paclitaxel from gelatin microspheres for the prevention of recurrence of peritoneal carcinomatosis in advanced ovarian cancer. Sci Rep 2019; 9:14881.

Abstract
Patients with advanced ovarian cancer develop recurrence despite initial treatment response to standard treatment of surgery and intravenous/intraperitoneal (IP) chemotherapy, partly due to a limited peritoneal exposure time of chemotherapeutics. Paclitaxel-loaded genipin-crosslinked gelatin microspheres (PTX-GP-MS) are evaluated for the treatment of microscopic peritoneal carcinomatosis and prevention of recurrent disease. The highest drug load (39.2 µg PTX/mg MS) was obtained by immersion of GP-MS in aqueous PTX nanosuspension (PTXnano-GP-MS) instead of ethanolic PTX solution (PTXEtOH-GP-MS). PTX release from PTX-GP-MS was prolonged. PTXnano-GP-MS displayed a more controlled release compared to a biphasic release from PTXEtOH-GP-MS. Anticancer efficacy of IP PTX-GP-MS (PTXEtOH-GP-MS, D = 7.5 mg PTX/kg; PTXnano-GP-MS D = 7.5 and 35 mg PTX/kg), IP nanoparticular albumin-bound PTX (D = 35 mg PTX/kg) and controls (0.9% NaCl, blank GP-MS) was evaluated in a microscopic peritoneal carcinomatosis xenograft mouse model. PTXnano-GP-MS showed superior anticancer efficacy with significant increased survival time, decreased peritoneal carcinomatosis index score and ascites incidence. However, prolonged PTX release over 14 days from PTXnano-GP-MS caused drug-related toxicity in 27% of high-dosed PTXnano-GP-MS-treated mice. Dose simulations for PTXnano-GP-MS demonstrated an optimal survival without drug-induced toxicity in a range of 7.5-15 mg PTX/kg. Low-dosed PTXnano-GP-MS can be a promising IP drug delivery system to prevent recurrent ovarian cancer.

Abstract
Petadolex®, a defined butterbur extract has clinically proven efficacy against migraine attacks. However, spontaneous reports indicate cases of herbal induced liver injury (HILI). While most HILI patients presented mild serum biochemistry changes (<3 ULN, dose range 50 to 225 mg/day; treatment duration 4–730 days) nine developed severe HILI (average time-to-onset 103 days, ALT-range 3–153; AST 2–104-fold ULN). HILI cases resolved after medication withdrawal though two patients required liver transplantation. Liver biopsies revealed an inconsistent injury pattern, i.e. necrosis, macrovesicular steatosis, inflammation, cholestasis, and bile duct proliferation. Causality assessment rated 3 cases likely, 13 possible, 8 unlikely and 24 as unclassifiable/unclassified. Note, 22 patients reported hepatotoxic co-medications especially during periods of pain. A no-observable-adverse-effect-level at 15-fold of the maximal clinical dose (3 mg/kg/day MCD) was established for rats. At >45 and 90-fold MCD bile duct hyperplasia was observed but could not be confirmed in an explorative minipig study at 218-fold MCD. Human hepatocyte studies at 49-fold Cmax serum petasins (=active ingredient) and therapeutic Ibuprofen, Paracetamol and Naratriptan concentrations evidenced liver transaminase and CYP-monooxygenase changes. Collectively, Petadolex® HILI cases are rare, idiosyncratic and frequently confounded by co-medications. A physician-supervised self-medication plan with herbs and pain relief medication is needed to minimize risk for HILI.

Abstract
We previously found that the fifth epidermal growth factor-like domain of thrombomodulin (TME5) exerts cytoprotective and pro-angiogenic functions via G-protein coupled receptor 15 (GPR15). TME5 is comprised of three S-S bonds that divide it into three loops: A (TME5A), B (TME5B), and C (TME5C). Herein we identified the minimum structure of TME5 that produces favorable effects in vascular endothelial cells (ECs). We found that TME5C, composed of 19 amino acids, but not TME5A or TME5B, stimulated the proliferation of human umbilical vein endothelial cells (HUVECs) and human hepatic sinusoidal endothelial cells (HHSECs). Matrigel plug assays showed that TME5C stimulates in vivo angiogenesis. In addition, TME5C counteracted calcineurin inhibitor-induced apoptosis and vascular permeability in HUVECs and HHSECs. Western blot analysis indicated that exposure of either HUVECs or HHSECs to TME5C increased the levels of anti-apoptotic myeloid cell leukemia-1 protein in association with the activation of signal transduction pathways, including extracellular signal-regulated kinase, AKT, and mitogen-activated protein kinase p38. Importantly, TME5C did not affect the coagulation pathway in vitro The cytoprotective function of TME5C was mediated by cell surface-expressed GPR15, as TME5C was not able to protect vascular ECs isolated from Gpr15 knock-out (KO) mice. Strikingly, TME5C successfully ameliorated sinusoidal obstruction syndrome in a murine model by counteracting the reduction of sinusoidal EC numbers. Taken together, the cytoprotective and pro-angiogenetic functions of TM are preserved in TME5C. The use of TME5C may be a promising treatment strategy to prevent or treat lethal complications, such as sinusoidal obstruction syndrome, whose pathogenesis is based on endothelial insults.

Abstract
We retrospectively identified 89 consecutive patients from January 2004 to January 2012 to investigate efficacy of direct intrahepatic portocaval shunt (DIPS) combined with inferior vena cava (IVC) stenting for sinusoidal obstruction syndrome (SOS) associated with hepatotoxicity of pyrrolizidine alkaloids. Indications for treatment were variceal hemorrhage and/or refractory ascites. Patients were treated with DIPS plus IVC stenting (group A, n=68) or DIPS alone (group B, n=21). A technical success rate of 100% was obtained in all 89 patients, and there were no early procedure-related adverse events or 30-day mortality. Mean portosystemic gradient decreased in both groups. Changes in aspartate and alanine aminotransferases and total bilirubin did not differ between the groups. Ascites disappeared in group A but was not obvious in group B until IVC stenting. During follow-up, recurrent bleeding and ascites and incidence of hepatic encephalopathy did not differ between the groups. The 1-, 3-, and 5-year survival rate was 98, 89.59, and 80%, respectively. Satisfactory clinical results were obtained for combined DIPS and IVC stenting for SOS associated with pyrrolizidine-alkaloid-related decompensated cirrhosis.

Abstract
RATIONALE Hepatic vein occlusive disease (HVOD) is a rare complication after liver transplantation, which is characterized by nonthrombotic, fibrous obliteration of the small centrilobular hepatic veins by connective tissue and centrilobular necrosis in zone 3 of the acini. HVOD after solid organ transplantation has been reported; recently, most of these reports with limited cases have documented that acute cell rejection and immunosuppressive agents are the major causative factors. HVOD is relatively a rare complication of liver transplantation with the incidence of approximately 2%. PATIENT CONCERNS A 59-year-old male patient with alcoholic liver cirrhosis underwent liver transplantation in our center. He suffered ascites, renal impairment 3 months after the surgery while liver enzymes were in normal range. DIAGNOSES Imagining and pathology showed no evidence of rejection or vessels complications. HVOD was diagnosed with pathology biopsy. INTERVENTIONS Tacrolimus was withdrawn and the progression of HVOD was reversed. OUTCOMES Now, this patient has been followed up for 6 months after discharge with normal liver graft function. LESSONS The use of tacrolimus in patients after liver transplantation may cause HVOD. Patients with jaundice, body weight gain, and refractory ascites should be strongly suspected of tacrolimus related HVOD.

Abstract
RATIONALE AND OBJECTIVE The computed tomography (CT) features of hepatic veno-occlusive disease (HVOD) could play a role in its diagnosis. We aimed to perform a meta-analysis of studies examining the CT features of HVOD. METHODS Relevant studies published up to May 3, 2017 were searched in major electronic databases. The extracted data included the proportion of various CT features in patients with HVOD. The meta-analysis was conducted using R 3.3.3 with the "meta" package. RESULTS Eleven studies were included. The studies involved 326 patients with a mean age range of 50.2-58.9 years, and the proportion of female patients ranged from 20% to 57.5%. The meta-analysis showed the pooled proportion of CT features: hepatic parenchyma with heterogeneous hypoattenuation (81.05%, 95% confidence interval [CI]: 56.97%-93.25%), patchy enhancement in the portal venous phase (87.09%, 95% CI: 75.15%-93.77%) with or without a narrow or invisible hepatic vein (71.02% 95% CI: 42.09%-89.20%), gallbladder wall edema (65.51%, 95% CI: 28.98%-89.84%), and patchy heterogeneous enhancement in the arterial phase (44.36%, 95% CI: 29.98%-59.76%) with or without slightly enlarged hepatic artery (56.61%, 95% CI: 40.62%-71.33%). CONCLUSION Hepatic parenchyma with heterogeneous hypoattenuation and patchy enhancement with or without narrowing or an invisible hepatic vein in the portal venous or equilibrium phase may be the most important CT feature for diagnosing HVOD.

Abstract
GS2 is a rare autosomal recessive disease characterized by hypopigmentation, variable immunodeficiency with HLH. HSCT is the only curative treatment for GS2. We analyzed the outcome of 10 children with GS2 who underwent HSCT at our center between October 1997 and September 2013. The median age of the patients at transplant was 13.5 months (range, 6-58 months). All of the patients developed HLH before HSCT and received HLH 94 or HLH 2004 protocols. Donors were HLA-identical relatives in 8 patients, HLA-mismatched relatives in 2 patients. Engraftment was achieved in all except one patient. None of the patients developed acute GVHD. Chronic GVHD occurred in one and veno-occlusive disease occurred in four patients. Eight of the patients are under remission without any neurologic sequelae-median time of disease-free survival is 92.4 months. The present study shows successful transplant outcome without long-term neurologic sequelae in patients with GS2 who underwent HSCT from HLA-related donors.

Abstract
PURPOSE Defibrotide is an agent used to treat sinusoidal obstruction syndrome (SOS/VOD) in patients undergoing haemopoietic stem cell transplantation. The aim of this study was to evaluate the effectiveness of defibrotide used within institutional guidelines for the treatment of SOS/VOD in patients undergoing haemopoietic stem cell transplantation (HSCT). METHODS Data for 23 patients was retrospectively reviewed to evaluate the effectiveness of defibrotide and the utility of response criteria to direct therapy as specified within institution guidelines. Patients met institutional criteria for a diagnosis of SOS/VOD based on predominantly Baltimore criteria and received defibrotide. Stabilisation or improvement in symptoms and biochemical markers was required for continuation of therapy with defibrotide. RESULTS Overall, 14 patients responded to therapy. Survival at day 100 post HSCT was 70%. Median serum (total) bilirubin concentrations in all evaluable patients had decreased at days 5 and 10 (p < 0.001). There was a proportional reduction in median weight of 4% by day 5 and 6.6% by day 10 (p < 0.001). On cessation of defibrotide, there was a decrease in the proportion of patients exhibiting hepatomegaly (p = 0.02), ascites (p < 0.01) and requiring oxygen supplementation (p < 0.01), with 70% survival at day 100 post HSCT. CONCLUSION Defibrotide to treat SOS/VOD and continued based on attainment of early response was effective management of this condition. Defibrotide should be considered in any consensus protocol providing guidance on the management of SOS/VOD, with future studies considered to assess appropriate time points for response to therapy during treatment.

Abstract
The aim of this study was to determine usefulness of measurements of maximal systolic velocity of the hepatic artery with Doppler ultrasonography in the diagnosis of venoocclusive disease (VOD) after hematopoietic stem cell transplantation. We prospectively obtained 5 sonograms per patient: pretransplantation, day +1, +7, +14, and +28 on 36 nonconsecutive children who underwent hematopoietic stem cell transplantation. We examined the hepatic artery, the portal, hepatic and splenic veins, the thickness of the gallbladder wall, the presence of ascites, and the liver and spleen size. The diagnosis of VOD was based on clinical and laboratory data. Patients were divided into 2 groups: those with VOD (n=18) and those without VOD (n=18). The variance of 2 groups was analyzed. Vmax of the hepatic artery had a strong correlation with clinical VOD diagnosis (P<0.001). There was no statistically significant difference in the other Doppler parameters. The results of our study showed that the measurement of Vmax of the hepatic artery can provide important support in the diagnosis of VOD and can be useful in the follow-up of treatment response.

Abstract
Hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), represents the most frequent complication in patients in early phase following hematopoietic stem-cell transplantation (HSCT). In its severe form, VOD/SOS can be associated with multiorgan failure and with a mortality rate >80% by day +100. Defibrotide (DF) (a mixture of 90% single-stranded phosphodiester oligonucleotides and 10% double-stranded phosphodiester oligonucleotides derived from controlled depolarization of porcine intestinal mucosal DNA) has been proposed for the treatment of SOS due to its ability to restore thrombo-fibrinolytic balance and protect endothelial cells. The present review highlights why the mechanisms of action of DF allow its successful use in the prevention and treatment of SOS following HSCT.

Abstract
Sinusoidal obstruction syndrome, previously known as veno-occlusive disease (VOD/SOS), is a complication in patients undergoing haemopoietic stem cell transplantation (HSCT). Severe VOD/SOS, including progression to multi-organ failure, has resulted in a mortality of greater than 80%. Defibrotide's varying pharmacological actions, particularly on endothelial cells, make it is a useful agent to consider for prophylaxis and treatment of VOD/SOS. Barriers to its routine use include the high acquisition cost and the fact that neither the oral or parenteral formulations are licensed products in many countries at this time. This review summarises available literature on the use of defibrotide in the management of VOD/SOS. Publications consist predominantly of single centre cohort studies and case series. Available evidence indicates that defibrotide is effective in the management of VOD/SOS. Using defibrotide prophylaxis should also be considered, especially in the paediatric setting, where there are available results from a large, open label, randomized controlled trial. Patient outcome data from the larger studies and compassionate programs can inform consensus recommendations on dosing regimen and criteria for the treatment of VOD/SOS with defibrotide in the adult population. The reviewed literature indicates an effective and safe dose for treatment is 25mg/kg/day, continued for at least 14days or until complete response is achieved. Further studies are required to determine the optimal dose and duration of treatment in both paediatric patients and adults. Recent recommendations and a phase 3 trial using historical controls indicate that defibrotide should be included as a pharmacotherapy option in protocols guiding management of VOD/SOS.

Abstract
Hepatic sinusoidal obstruction syndrome (SOS) is a life-threatening syndrome that generally occurs as a complication after hematopoietic stem cell transplantation or, less commonly, after conventional chemotherapy. Regarding SOS in rhabdomyosarcoma patients who received conventional chemotherapy, the doses of chemotherapeutic agents are associated with the development of SOS. Several cases of SOS in rhabdomyosarcoma patients after receiving chemotherapy with escalated doses of cyclophosphamide have been reported. Here, we report on a 9-year-old female with rhabdomyosarcoma who developed severe SOS after receiving chemotherapy consisting of vincristine, actinomycin-D, and a moderate dose of cyclophosphamide. She was treated successfully with defibrotide without sequelae to the liver.

Abstract
BACKGROUND & AIMS Injury to liver sinusoidal endothelial cells (LSECs) is thought to be the initial factor for Hepatic veno-occlusive disease, a severe complication after haematopoietic stem cell transplantation (HSCT). Endothelial progenitor cells (EPCs) have the capacity to differentiate into endothelial cells and play a critical role in vasculogenesis, tissue regeneration and repair. Whether EPCs infusion ameliorates LSECs injury remains unclear. The aim of this study was to evaluate the effects of EPCs on liver injury in mice after HSCT. METHODS Mice received HSCT without or with EPCs infusion (HSCT + EPCs). Untreated mice were used as control. Liver and whole blood were collected post HSCT and used for the analysis of pathology of liver sinusoidal endothelial cells (LSECs) and hepatocytes, liver ultrastructure, function, level of IL-6, TNF-α and platelet activation. RESULTS Severe LSECs injury, hepatocyte damage, abnormal liver function was observed in HSCT group. In addition, increased P-selectin expression and secretion of IL-6, TNF-α was also found. However, all the above changes were alleviated in HSCT + EPCs at all the time points and normalized at the endpoint. Meanwhile, EPCs-induced repair of LSECs and hepatocytes was totally inhibited by the addition of anti-VE-cadherin antibody. CONCLUSIONS EPCs infusion ameliorated the damage to LSECs and hepatocytes as well as reduced secretion of IL-6, TNF-α and inhibited platelet activation after HSCT, leading to improved liver function, suggesting EPCs might be a new therapeutic strategy in the prophylaxis of liver injury after HSCT.

Abstract
Sinusoidal obstruction syndrome (SOS), previously known as hepatic veno-occlusive disease, is a rare disorder in solid organ transplant patients, and is an uncommon complication after liver transplantation. Severe SOS with hepatic failure causes considerable mortality. Tacrolimus has been reported to be an offending agent, which potentially plays a role in the pathophysiological process of SOS. SOS due to tacrolimus has been reported in lung and pancreatic transplantations, but has never been described in a liver transplant recipient. Herein, we present a case of SOS after liver transplantation, which was possibly related to tacrolimus. A 27-year-old man developed typical symptoms of SOS with painful hepatomegaly, ascites and jaundice after liver transplantation, which regressed following withdrawal of tacrolimus. By excluding other possible predisposing factors, we concluded that tacrolimus was the most likely cause of SOS.

Abstract
The insertion of a transjugular intrahepatic portosystemic shunt (TIPS) is a minimally invasive procedure used to relieve the signs and symptoms of portal hypertension in patients with liver disease. The most common indications for placement are refractory ascites and variceal hemorrhage. In properly selected candidates, TIPS placement can serve as a bridge to liver transplantation. Expertise in TIPS placement after transplantation has significantly increased, which has allowed the procedure to become a viable option for retransplant candidates suffering the consequences of recurrent portal hypertension due to portal vein thrombosis, recurrent liver disease, or hepatic venous outflow obstruction (HVOO). However, TIPSs in liver transplant recipients are associated with a lower clinical response rate and a higher rate of complications in comparison with patients with native liver disease, and they are, therefore, generally reserved for patients with a Model for End-Stage Liver Disease (MELD) score ≤ 15 and ≤ 12 in patients with HCV. The role of TIPS placement in nonliver transplant recipients has been well studied in large trials, and it translates well into clinical applicability to candidates for orthotopic liver transplantation (OLT). However, the experience with OLT recipients is heterogeneous and restricted to small series. Thus, we focus here on reviewing the current literature and discussing the proper use of TIPSs in liver transplant recipients.

Abstract
The present case report describes the diagnosis and treatment of a patient with veno-occlusive disease (VOD) following liver transplantation. Combining the clinical data and relevant literature, the study aimed to consider the causes of VOD following liver transplantation, and the pathogenesis, clinical diagnosis and auxiliary examination features of VOD. A 42-year-old man who had a long history of taking traditional Chinese medicine (essential components unknown) underwent an orthotropic liver transplantation on January 14, 2011, due to small venous occlusion disease of the liver. The patient was treated with tacrolimus as an antirejection therapy following the surgery, and gradually developed right upper quadrant pain and fatigue. The examination results were consistent with the diagnostic standards for VOD. Following treatment with methylprednisolone, the patient was treated with alprostadil and Danhong injections. Forty days later, the patient’s total bilirubin (TBIL) level was observed to have decreased significantly, the liver function had returned to normal and the ascites had decreased, but had not completely disappeared. The patient then underwent a transjugular intrahepatic portosystemic shunt (TIPS) procedure, following which the ascites were shown to have completely disappeared.

In the 25 years since the first TIPS intervention has been performed, technical standards, indications, and contraindications have been set up. The previous considerable problem of shunt failure by thrombosis or intimal proliferation in the stent or in the draining hepatic vein has been reduced considerably by the availability of polytetrafluoroethylene (PTFE)-covered stents resulting in reduced rebleeding and improved survival. Unfortunately, most clinical studies have been performed prior to the release of the covered stent and, therefore, do not represent the present state of the art. In spite of this, TIPS has gained increasing acceptance in the treatment of the various complications of portal hypertension and vascular diseases of the liver.

Abstract
Prothrombotic haematological disorders, in particular myeloproliferative disorders, are identified in a significant proportion of patients with Budd-Chiari syndrome and portal vein thrombosis (PVT). Multiple prothrombotic disorders may coexist. PVT is diagnosed in one fourth of patients with cirrhosis and is more common with advanced liver disease and hepatocellular carcinoma. PVT in cirrhosis can precipitate decompensation. Intrahepatic microthrombosis may play a role in the pathogenesis of hepatic fibrosis. Sinusoidal obstruction syndrome is usually a complication of myeloablative treatment before haematopoietic stem cell transplantation. Post-transplant lymphoproliferative disorders can complicate liver transplantation and are related to Epstein-Barr virus infection. Hepatitis B reactivation in patients receiving chemotherapy for haematological malignancies is very common without pre-emptive treatment, and can lead to liver failure. Liver involvement is common in primary haematological diseases, such as haemolytic anaemias, lymphomas and leukaemia.

Abstract
Backgroud The occurrence of Hepatic veno-occlusive disease (VOD) is rale liver disease. However, severe VOD is often lethal and one of the most common causes of death following stem cell transplantation (SCT). Case Reports: Case 1 was a 30-year-old woman who was diagnosed as Budd-Chiari syndrome with liver failure. She was admitted to our department to undergo liver transplantation. Four days after admission, she underwent liver transplantation. Her liver explant showed VOD. Case 2 was a 74-year-old woman who was admitted to a community hospital for further examination. Her condition continued to deteriorate with liver failure, and she died 39 days after admission. Liver autopsy also showed VOD. Either of the patients had difficulty in diagnose as VOD. Neither of the patients had a history of SCT. Conclusions: VOD should be considered as a cause of acute hepatic failure, even if the patient has no history of SCT.

Abstract
PURPOSE Hematopoietic stem cell transplant (HSCT) recipients are at high risk in the setting of percutaneous liver biopsy as a result of comorbid coagulopathy and ascites, and are commonly referred to undergo transjugular liver biopsy. The present study was performed to assess the safety and utility of transjugular liver biopsy in HSCT recipients and to analyze the correlation between corrected hepatic sinusoidal pressure gradient (CHSPG) and pathologic diagnoses. MATERIALS AND METHODS Data from reports of transjugular liver biopsy procedures, pathology reports, and laboratory values of 141 consecutive HSCT recipients who underwent transjugular liver biopsy with pressure measurement between January 2005 and August 2011 in a single institution were retrospectively reviewed and analyzed. RESULTS A total of 166 biopsy procedures were performed in 141 patients. Technical success rate was 98.8%. Biopsy was diagnostic in 95.7% of patients. There were three major complications (1.8%), including one death. CHSPG in patients with venoocclusive disease (VOD) was significantly higher (P<.001) than in those without VOD (16.2 mm Hg±9.2 vs 5.6 mm Hg±3.7). A CHSPG of 10 mm Hg or higher was 90.8% specific and 77.3% sensitive for VOD. CONCLUSIONS The present data show that transjugular liver biopsy is a relatively safe procedure that provides important information for the clinical management of patients with HSCT. Measurement of CHSPG during the procedure can support the diagnosis of VOD.

Abstract
Hepatic veno-occlusive disease (HVOD) is one of the main complications of hematopoietic stem cell transplantation (HSCT). Its pathogenesis is mainly associated with a local hypercoagulable state, and the main pathological changes are occlusion of terminal hepatic venules and necrosis of liver cells. The diagnosis of HVOD depends on a liver biopsy. Identifying and avoiding the risk factors are main measures to reduce the incidence and mortality of HVOD, since drug prophylaxis lacks exact effect and has significant adverse reactions. Defibrotide is the most effective therapy for HVOD, while the efficacy of other drugs still needs to be verified. In this paper, we will review the current status and future prospects of clinical research of HVOD.

Abstract
AIM We conducted this study to evaluate the role of multidetector computed tomography (MDCT) in diagnosing and differential diagnosis hepatic veno-occlusive disease (HVOD), and as well as assessing the clinical therapeutic effects. METHODS From 2007 to 2010, 10 inpatients with weight increasing, liver pains, ascites, jaundice and history of taking gynura rhizome before hospitalization were scanned with a 64-MDCT. The data were reconstructed every 0.625 mm and reviewed using multiplanar reconstruction (MPR) and liver CT angiography (CTA) on a GE AW4.2 workstation. Patients were re-scanned with MDCT after medication so that the clinical therapeutic effect could be evaluated before the patients discharging from hospital. RESULTS In 10 HVOD patients, the diagnoses of MDCT were coincident with clinical results. All patients had ascites and pleural fluid, hepatomegaly except the caudate lobe in MDCT. Failure to view hepatic veins in hepatic 3 phase scans, but portal veins and inferior vena cava were unobstructed. In portal-phase, hepatic enhancements were non-uniform. Three patients were incorrectly diagnosed before hospital admission. All patients improved significantly after hepato-protection and supporting therapy. No ascites, hydrothorax, hepatomegaly and obstruction of hepatic veins were observed by MDCT before patients were discharged from hospital. CONCLUSION Multidetector computed tomography combined with MPR and liver CTA images are helpful in the diagnosis and differential diagnosis of HVOD and in the evaluation of clinical therapeutic effects.

Abstract
Sinusoidal obstruction syndrome (SOS) is a rare, life-threatening clinical syndrome resulting from sinusoidal congestion, and it is characterized by hepatomegaly, ascites, weight gain, and jaundice. The frequency of this condition after liver transplantation (LT) is low, but when SOS is severe and refractory to medical therapy, the ultimate solution is retransplantation. We describe a patient with SOS after LT who was successfully treated by the placement of a transjugular intrahepatic portosystemic shunt (TIPS). Although information on this approach is scarce because of the low incidence of SOS in LT patients, we review the available literature on treating this condition with a TIPS. On the basis of the reported information and our patient's outcome, we suggest that prompt TIPS placement can be considered for SOS when medical treatment fails. Nonetheless, a formal assessment and prospective studies are needed to confidently indicate TIPS placement in this situation.

Abstract
A 60-year-old man was admitted to Tenri Hospital complaining of erythema and abdominal distention. There were marked liver damage and hypereosinophilia. The patient was suffering from portal hypertension and coagulation disorder. We diagnosed the patient clinically as suffering from veno-occlusive disease, or sinusoidal obstructive syndrome (SOS). The pathological finding of the liver biopsy specimen was compatible with SOS. All of the manifestations, liver function test, and hemodynamics subsided shortly after administration of steroid treatment and ursodeoxycholic acid. The pathogenesis was not identified but some allergic reaction was suspected.

Abstract
Portal hypertension is characterized by an increase in portal pressure (> 10 mmHg) and could be a result of cirrhosis of the liver or of noncirrhotic diseases. When portal hypertension occurs in the absence of liver cirrhosis, noncirrhotic portal hypertension (NCPH) must be considered. The prognosis of this disease is much better than that of cirrhosis. Noncirrhotic diseases are the common cause of portal hypertension in developing countries, especially in Asia. NCPH is a heterogeneous group of diseases that is due to intrahepatic or extrahepatic etiologies. In general, the lesions in NCPH are vascular in nature and can be classified based on the site of resistance to blood flow. In most cases, these disorders can be explained by endothelial cell lesions, intimal thickening, thrombotic obliterations, or scarring of the intrahepatic portal or hepatic venous circulation. Many different conditions can determine NCPH through the association of these various lesions in various degrees. Many clinical manifestations of NCPH result from the secondary effects of portal hypertension. Patients with NCPH present with upper gastrointestinal bleeding, splenomegaly, ascites after gastrointestinal bleeding, features of hypersplenism, growth retardation, and jaundice due to portal hypertensive biliopathy. Other sequelae include hyperdynamic circulation, pulmonary complications, and other effects of portosystemic collateral circulation like portosystemic encephalopathy. At present, pharmacologic and endoscopic treatments are the treatments of choice for portal hypertension. The therapy of all disorders causing NCPH involves the reduction of portal pressure by pharmacotherapy or portosystemic shunting, apart from prevention and treatment of complications of portal hypertension.

Abstract
BACKGROUND AND AIM To investigate the therapeutic effect of ligustrazine on hepatic veno-occlusive disease (HVOD) induced by Gynura segetum and the possible mechanism of it. METHODS Female Kunming mice (115) were randomly divided into four groups, gavaged with 30 g/kg per day Gynura segetum (group A), 30 g/kg per day Gynura segetum + 100 mg/kg per day ligustrazine (group B), 30 g/kg per day Gynura segetum + 200 mg/kg per day ligustrazine (group C) or 30 mL/kg per day phosphate-buffered saline (PBS) (group D). Thirty days later, all of the mice were killed. Blood samples and livers were harvested. Histological changes were evaluated by light microscopy. Liver function was measured, and the expression of tissue factor (TF), early growth response factor-1 (Egr-1) and nuclear factor-KBp65 (NF-KBp65) were determined by reverse transcription-polymerase chain reaction and Western blot. RESULTS A total of 24 mice in group A developed HVOD. Compared with the controls, they had increased liver ratio, serum total bilirubin (TBIL), direct bilirubin (DBIL), transaminase and decreased albumin (ALB) (P < 0.05). Administration of ligustrazine improved the clinical signs and biochemistry parameters in a dose-dependent manner. Compared with group A, the expression of TF, Egr-1 and NF-KB p65 decreased in groups B and C (P < 0.05). CONCLUSION Ligustrazine has a therapeutic effect on HVOD, improving clinical manifestations and liver function. The possible mechanism may be that ligustrazine could reduce the expression of TF by downregulating the expression of transcription factors: Egr-1 and NF-KB p65.

Abstract
Radioembolization (RE), also termed selective internal radiation therapy (SIRT), has been gradually introduced to the clinical arsenal of cytoreductive modalities in recent years. There is growing evidence for efficiency in liver tumors of various entities, with the most prominent ones being hepatocellular carcinoma, colorectal cancer, and neuroendocrine tumors. Hepatic metastases of numerous other tumor entities including breast cancer, cholangiocarcinoma, and pancreatic cancer are treatment-sensitive, even when being refractory to other treatment modalities such as bland-embolization, regional, or systemic chemotherapy. The antitumor effect of SIRT is related to radiation rather than embolization, with extraordinary high local radiation doses obtained selectively at the site of viable tumor and little affection of the surrounding normal liver tissue. Morphologic changes after RE may pose difficulties for interpretation in conventional restaging with regard to tumor viability and true response to treatment. Therefore, functional imaging, that is, metabolic imaging with (18)F fluorodeoxyglucose positron emission tomography (computed tomography) in the majority of treated tumors, is regarded the gold standard in this respect and should be included for pre- and post-SIRT assessment. To prevent serious toxicity to be associated with the potent antitumor efficacy, meticulous pretreatment evaluation is of particular importance. Improvements in predicting dosimetry will help optimize treatment and patient selection. Nuclear medicine procedures are essential for planning, performing, and monitoring of RE. However, the interdisciplinary aspect of patient management has to be emphasized for this particular treatment form. As SIRT is moving forward from the salvage setting indication to the use in earlier stages of hepatic tumor disease and with the advent of new treatment protocols and targeted therapies, embedding SIRT into a multidisciplinary approach will become even more important. This article focuses on procedural and technical aspects for selection, preparation, and performance of treatment as well as post-therapeutic monitoring and response assessment.

Abstract
Here we report a case of administration of defibrotide in an 11 months old infant with hepatic veno-occlusive disease during chemotherapy for nephroblastoma. He presented with abdominal distension, a weight gain of 15%, ascites, hepatomegaly with right upper quadrant pain, thrombocytopenia and hypertransaminasemia. Despite therapy, his clinical conditions aggravated, and, therefore intravenous administration of defibrotide on a compassionate-use basis was started. The dosage was 15 mg/kg/day in 4 divided doses, which was increased gradually (in 3 days) to 40 mg/kg/day in 4 divided doses. Defibrotide proved safe and effective in resolving clinical symptoms and normalizing serological findings in the syndrome.

Abstract
Vascular endothelial cells are an exposed target tissue for immune-mediated injury during graft-versus-host disease (GVHD). However, widespread endothelial death resulting in multi-organ failure similar to that in hyperacute solid-organ transplant rejection is not observed during GVHD. The rather mild endothelial injury seen in histological samples from affected skin biopsies contrasts with severe epithelial injury observed sometimes simultaneously. The elucidation of the mechanisms that influence endothelial susceptibility to immune-mediated injury would explain this paradox and may help to separate GVHD from the beneficial graft-versus-leukaemia effect. Transplant-associated microangiopathy, veno-occlusive disease and accelerated arteriosclerosis are vascular injury syndromes that occur after allogeneic stem-cell transplantation. Biomarkers are needed to identify individuals at risk of developing these complications. Treatments that have been found to be particularly effective for these specific endothelial injury syndromes need to be tested in larger clinical trials.
