Abstract
Kidney replacement therapy (KRT) is a common supportive treatment for renal dysfunction, especially acute kidney injury. However, critically ill or immunosuppressed patients with renal dysfunction often have dysfunction in other organs as well. To improve patient outcomes, clinicians began to initiate kidney replacement therapy in situations where nonrenal conditions may lead to acute kidney injury, such as septic shock, hematopoietic stem cell transplantation, veno-occlusive renal disease, cardiopulmonary bypass, chemotherapy, tumor lysis syndrome, hyperammonemia, and various others. In this review, we discuss the use of various modes of kidney replacement therapy in treating renal and nonrenal complications to illustrate why kidney support therapy is a more appropriate terminology than kidney replacement therapy.

Abstract
Hepatic veno-occlusive disease (HVOD) is a life-threatening complication of bone marrow stem cell transplantation. The understanding of this clinical condition is hampered by the lack of suitable animal models. Here, we present a murine (BALB/c-based) model of HVOD induced by allogeneic hematopoietic stem cell transplantation (allo-HSCT). The chimerism rate of bone marrow was measured on days 5 and 10, while the chimerism rate of peripheral blood was measured on day 15 after allo-HSCT. Percentages of peripheral reticulocytes and serum levels of bilirubin and alanine aminotransferase (as liver function tests) were measured on days 5, 10, 15, 20, and 30. Livers were obtained on days 5, 10, 15, 20, and 30, and fixed in formaldehyde or glutaric dialdehyde. Liver slices were processed using the hematoxylin-eosin, Masson's trichrome, or immunohistochemistry staining, and examined by light or transmission electron microscopy. Sinusoidal damages were the earliest pathological changes occurring in the allo-HSCT-induced HVOD, followed by coagulative necrosis of liver cells. The liver cell necrosis was later attenuated and sinusoidal endothelial cell morphology improved. However, on day 30, the edema and necrosis of liver cells became aggravated again. Furthermore, sinusoidal lining cell regeneration and partly attenuated liver cell necrosis were followed by the moderate to severe central vein fibrosis. In conclusion, we have successfully established a murine model of HSCT-HVOD. This model develops moderate to severe HVOD which cannot heal without intervention.

Abstract
Hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome, is a major complication of hematopoietic stem cell transplantation and it carries a high mortality. Prophylaxis for hepatic VOD is commonly given to transplant recipients from the start of conditioning through the early weeks of transplant. However, high quality evidence from randomized controlled trials is scarce with small sample sizes and the trials yielded conflicting results. Although various treatment options for hepatic VOD are available, most have not undergone stringent evaluation with randomized controlled trial and therefore it remains uncertain which treatment offers real benefit. It remains controversial whether VOD prophylaxis should be given, which prophylactic therapy should be given, who should receive prophylaxis, and what treatment should be offered once VOD is established.

Abstract
BACKGROUND AND AIM Hepatic dysfunction is a common cause of morbidity and mortality in bone marrow transplant recipients. During the complex clinical management of these patients, liver biopsies may be obtained during evaluation of abnormal liver tests. The purpose of our study was to assess the safety and use of liver biopsy in this patient population. METHODS In total, 1700 bone marrow transplants were performed at our institution from June 1982 to December 2002. Data from patients who underwent liver biopsy after their transplant were reviewed once they were identified through a computerized medical index system. Impact of the histological diagnosis on subsequent patient management was obtained from clinical records. The histological diagnosis made by dedicated hepatopathologists was used as the 'gold standard' to assess the reliability of clinical diagnosis. RESULTS Sixty-one patients, comprising 39 males and 22 females, had a liver biopsy performed (27 transjugular, 29 percutaneous, four laparoscopic, one not specified). As a result of liver biopsy, management was changed in 37% of patients and included addition of medical therapy in 11 and cessation of therapy in five patients. Complications from the liver biopsy were observed in 15 (25%) patients and involved 10 cases of pain or bleeding at the biopsy site, four subcapsular hemorrhages, and one arrhythmia leading to death. CONCLUSION Liver biopsy, although infrequently obtained during the assessment of hepatic dysfunction in the bone marrow transplant population, can serve as an important diagnostic tool with a significant impact on the clinical management of these patients. Although we observed a higher complication rate, the majority of them were minor.

Abstract
Hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), remains one of the most serious and common complications after myeloablative hematopoietic stem cell transplantation (HSCT). Clinical diagnosis of hepatic VOD is based on the clinical triad of (1) painful hepatomegaly, (2) hyperbilirubinemia and (3) unexplained fluid retention. While milder cases usually resolve spontaneously, severe VOD is associated with a grim prognosis. Defibrotide (DF), a polydisperse mixture of single-stranded oligonucleotide with antithrombotic and fibrinolytic effects on microvascular endothelium, has emerged as an effective and safe therapy for patients with severe VOD. Multiple studies, including a recent large international multicenter phase II clinical trial, have demonstrated 30-60% complete remission rates with DF, even among patients with severe VOD and multiorgan failure. This article will review our current understanding of hepatic VOD, and update the clinical trial experience with DF and other potential therapies for this feared transplant complication.

Abstract
Our goal is to provide a detailed review of veno-occlusive disease (VOD), Budd-Chiari syndrome (BCS), and congestive hepatopathy (CH), all of which results in hepatic venous outflow obstruction. This is the first article in which all three syndromes have been reviewed, enabling the reader to compare the characteristics of these disorders. The histological findings in VOD, BCS, and CH are almost identical: sinusoidal congestion and cell necrosis mostly in perivenular areas of hepatic acini which eventually leads to bridging fibrosis between adjacent central veins. Tender hepatomegaly with jaundice and ascites is common to all three conditions. However, the clinical presentation depends mostly on the extent and rapidity of the outflow obstruction. Although the etiology and treatment are completely different in VOD, BCS, and CH; the similarities in clinical manifestations and liver histology may suggest a common mechanism of hepatic injury and adaptation in response to increased sinusoidal pressure.

Abstract
Hepatic veno-occlusive disease (HVOD) is rarely encountered and easily misjudged as Budd-Chiari syndrome. It is often related to stem cell transplantation in recent years. We report a case of HVOD that is related to ingestion of some palatable local dishes. The diagnosis was confirmed by liver biopsy pathology with specific observation of inflammatory changes and fibrosis of venules intima, dilated sinusoids and central veins. Chronic diarrhea is unique for this case as a result of ingesting harmful stuffs. This case demonstrated that supervision and instruction of food recipe and traditional medicine are crucial, and prompt diagnosis, supportive care and specific treatment are essential to decreasing the morbidity and mortality of HVOD.

Abstract
Hepatic sinusoidal obstruction syndrome is frequently linked to high-dose chemotherapy/total-body irradiation in recipients of haematopoietic stem cell transplantation, long-term use of azathioprine after organ transplantation and other chemotherapeutic agents. The incidence of hepatic sinusoidal obstruction syndrome varies from 0% to 70%, and is decreasing. Disease risk is higher in patients with malignancies, hepatitis C virus infection, those who present late, when norethisterone is used to prevent menstruation, and when broad-spectrum antibiotics and antifungals are used during and after the conditioning therapy. Hepatic sinusoidal obstruction syndrome presents with tender hepatomegaly, hyperbilirubinaemia and ascites, and diagnosis is mainly clinical (Seattle and Baltimore Criteria). Imaging excludes biliary obstruction and malignancy, but cannot establish accurate diagnosis. Hepatic sinusoidal obstruction syndrome may be prevented by avoiding the highest risk regimens, using non-myelo-ablative regimens, and reducing total-body irradiation dose. Treatment is largely symptomatic and supportive, because 70-80% of patients recover spontaneously. Tissue plasminogen activator plus heparin improves outcome in <30% of cases. Defibrotide, a polydeoxyribonucleotide, is showing encouraging results. Transjugular intrahepatic porto-systemic shunt relieves ascites, but does not improve outcome. Liver transplantation may be an option in the absence of malignancy. Prognosis is variable and depends on disease severity, aetiology and associated conditions. Death is most commonly caused by renal or cardiopulmonary failure.

Abstract
Hepatic veno-occlusive disease (VOD), increasingly referred to as sinusoidal obstruction syndrome, is a well-recognized complication of hematopoietic stem cell transplantation and contributes to considerable morbidity and mortality. In the Western Hemisphere, VOD, classified as a conditioning-related toxicity, is most commonly caused by stem cell transplantation. VOD has been described after all types of stem cell transplantation, irrespective of the stem cell source, type of conditioning therapy, or underlying disease. Recognition of this disease in the posttransplantation setting remains a challenge in the absence of specific diagnostic features because many other more common conditions can mimic it. Limited therapeutic or preventive strategies are currently available for the management of VOD. In this review, we provide a comprehensive account of the pathophysiology of this disease as we understand it today, risk factors for its development, and the current state of knowledge regarding preventive and therapeutic options.
