Hepatitis C virus (HCV) infection is a worldwide public health problem associated with significant morbidity and mortality. In the context of liver transplantation, the demand for organs continues to exceed the supply, prompting the consideration of using organs from HCV-positive donors in HCV-negative recipients. The introduction of direct-acting antivirals (DAAs), which have demonstrated great efficacy in eradicating the virus, has made transplantation of organs from donors with HCV infection possible. The present article provides a brief review of the current evidence on the use of organs from HCV-infected patients...

BACKGROUND: Treatment of chronic hepatitis C virus (HCV) infection with direct-acting antivirals achieves a sustained virologic response rate higher than 95%. However, virologic failure remains a clinical challenge, and data on retreatment are limited, especially in special populations such as liver transplant (LT) recipients. OBJECTIVES: This study evaluated the sofosbuvir plus glecaprevir-pibrentasvir (GLE/PIB) regimen in LT recipients who had failed to a nonstructural protein 5A (NS5A) inhibitor-based regimen...

Kidney transplantation is the optimal therapy for end-stage kidney disease but limited by the available number of organs. Using HCV+ donors, both in HCV+ and HCV- recipients, is a rational response to the organ shortage. We review the historic experience using HCV+ donors in HCV+ recipients and assess long-term results. We also discuss contemporary practices, including the transplantation of HCV-viremic kidneys into HCV- recipients with different approaches to posttransplant HCV therapy.

Alcohol liver disease is one of the main indications for liver transplantation (LT). Currently, an abstinence period <6 months is required to include a patient with alcohol liver disease on the waiting list, a period that has not been shown to reduce the risk of relapse. Alcoholic hepatitis is characterized by hepatic decompensation secondary to recent, excessive consumption of alcohol, and LT may be the option in a well-selected group of patients who do not respond to medical treatment, but due to established sobriety intervals are excluded, this requires a change in the criteria established by the committees...

BACKGROUND AND RATIONALE: Chronic kidney disease remains an important risk factor for morbidity and mortality among LT recipients, but its exact incidence and risk factors are still unclear. MATERIAL AND METHODS: We carried out a retrospective cohort study of consecutive adults who underwent liver transplant (January 2009-December 2018) and were followed (at least 6 months) at our institution. CKD was defined following the Kidney Disease: Improving Global Outcomes (KDIGO) 2012 Clinical Practice Guidelines...

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare vascular tumor of less malignancy than hemangiosarcoma. In the rare unilobar cases, partial hepatectomy may be indicated with risk of aggressive recurrence; in extensive liver disease, even with extrahepatic involvement, liver transplantation has been performed successfully. Metastases are more common in the lung, peritoneum, lymph nodes, spleen, and nervous system. We present the case of an asymptomatic adolescent with HEHE with lung metastases and abdominal lymph node involvement who received a liver transplant with a favorable outcome...

Hepatocellular carcinoma (HCC) is more frequently manifesting as one of the main complications of cirrhosis of the liver, its principal risk factor. There have been modifications in its incidence over the past decade, related to an epidemiologic transition in the etiology of cirrhosis, with a decrease in the prevalence of hepatitis C and an increase in nonalcoholic fatty liver disease (NAFLD) as a cause, as well as the development of HCC in the non-cirrhotic liver due to NAFLD. Genetic markers associated with the disease have been identified, and surveillance and diagnosis have improved...

The hepatitis-associated aplastic anemia is one of the acquired bone marrow failure syndromes. It is a stereotyped form of presentation of aplastic anemia and accounts for 2 - 5 % of the cases in the West. Its treatment, which does not differ from that of aplastic anemia, consists of immunosuppression when bone marrow transplant is not possible. Nonetheless, during the SARS-CoV-2 pandemic, recommendations restricting the use of antithymocyte globulin to those cases with the highest risk of death have been issued, since the prognosis of CoViD-19 tends to be worse if administered...

Portopulmonary hypertension is an uncommon complication of portal hypertension, running a progressive course with a negative prognosis. Reports in pediatric patients are scarce with short follow up. We describe the case of decompensated cirrhosis who developed PoPH and resolved with liver transplantation, remaining asymptomatic after ten years of follow up.

BACKGROUND: It is not clear whether patients with some degree of immunosuppression have worse outcomes in SARS-CoV-2 infection, compared to healthy people. OBJECTIVE: To carry out a narrative review of the information available on infection by SARS-CoV-2 in immunosuppressed patients, especially patients with cancer, transplanted, neurological diseases, primary and secondary immunodeficiencies. RESULTS: Patients with cancer and recent cancer treatment (chemotherapy or surgery) and SARS-CoV-2 infection have a higher risk of worse outcomes...

BACKGROUND AND RATIONALE: Chronic kidney disease remains an important risk factor for morbidity and mortality among LT recipients, but its exact incidence and risk factors are still unclear. MATERIAL AND METHODS: We carried out a retrospective cohort study of consecutive adults who underwent liver transplant (January 2009-December 2018) and were followed (at least 6 months) at our institution. CKD was defined following the Kidney Disease: Improving Global Outcomes (KDIGO) 2012 Clinical Practice Guidelines...

BACKGROUND AND AIMS: Inflammatory bowel diseases (IBD) are chronic conditions that may be accompanied by autoimmune liver disease (AILD), most commonly primary sclerosing cholangitis (PSC). The objective of this study was to evaluate the behaviour of patients with IBD associated with AILD and compare a PSC group with a non-PSC group. METHODS: Medical records of patients with IBD associated with PSC, autoimmune cholangitis, primary biliary cholangitis, small-duct PSC, autoimmune hepatitis (AIH) and overlapping syndromes were assessed...

BACKGROUND: Ischemic type biliary lesions (ITBLs), a particular subset of non-anastomotic biliary strictures (NAS), are characterized by intra and extrahepatic strictures that occur in the absence of either hepatic artery thrombosis or stenosis. When they occur within the first year after liver transplantation their development is mostly related to ischemia-reperfusion injury (IRI). The indocyanine green plasma disappearance rate (ICG-PDR) might be able to predict the probability of IRI-induced graft damage after liver transplantation...

INTRODUCTION: Non-resectable liver tumors are one of the most frequent indications of pediatric liver transplantation. However, the usefulness of interventional techniques is still to be exploited. This is the case of a patient with a non-resectable liver sarcoma proposed for liver transplantation, which could be avoided as the tumor was fully resected following selective portal embolization combined with chemotherapy treatment. CLINICAL CASE: The patient was a 10-year-old female with a large hepatic mass compatible with undifferentiated PRETEXT III sarcoma treated according to the EpSSG RMS2005 protocol for high-risk tumors, but without achieving any reduction in volume...

ANTECEDENTES: En diciembre de 2019 se identificó en la ciudad de Wuhan, China, un nuevo beta coronavirus, el SARS-CoV-2, como agente causal de neumonía grave, conocida como COVID-19, lo cual ha provocado medidas estrictas de aislamiento, cierre de programas de trasplante hepático y la necesidad de modificar los protocolos de tratamiento. OBJETIVO: Documentar la información publicada sobre el impacto de la COVID-19 en la población con antecedente de trasplante hepático y establecer un protocolo de tratamiento...

OBJECTIVE: To evaluate the results of isolated liver and combined liver and kidney transplantation in a retrospective series of 32 patients with hepatorenal liver and kidney disease. MATERIALS AND METHODS: A retrospective observational study that enrolled patients with polycystic liver disease (PLD) and polycystic liver and kidney disease (PLKD) who were evaluated for transplantation between January 1999 and December 2019 at Hospital Clínic de Barcelona [Clinical Hospital of Barcelona]...

BACKGROUND: Cytomegalovirus (CMV) hepatitis constitutes a challenging diagnostic entity in liver transplant (LT) recipients. AIM: To determine the real incidence of CMV hepatitis using more specific diagnostic tools as those currently used before. METHODS: Retrospective/prospective study conducted in a hepatic transplant unit from 2009 to 2019. LT recipients with CMV specific or suggestive elements in histopathology of hepatic biopsies were included...

BACKGROUND: The Chilean allocation system for liver transplantation (LT) uses the MELD/PELD score to prioritize candidates on the waiting list. AIM: To assess if the Chilean allocation system for LT is equitable for pediatric candidates compared to their adult counterparts. MATERIAL AND METHODS: We used the Public Health Institute's registry between October 2011 and December 2017. We analyzed candidates with chronic hepatic diseases listed for LT...

Whilst prophylaxis of hepatitis B is universally accepted after liver transplantation (LT), national recommendations for the prophylaxis and treatment of hepatitis B virus (HBV) infection after LT are lacking in Spain. The aim of the VII consensus meeting organised by the Spanish Society of Liver Transplantation (SETH) was to set recommendations on the prophylaxis and treatment of hepatitis B after LT. The scientific evidence and strength of recommendations was evaluated by using the "Grading of Recommendations Assessment, Development and Evaluation" (GRADE) system...

INTRODUCTION: several indicators are available to assess liver graft survival, including the American DRI and the European ET-DRI. However, there are significant differences between transplant programs of different countries, and the previously mentioned indicators might be not valid in our setting. OBJECTIVES: the aim of the study was to describe a new national liver graft risk indicator based on the results obtained from the Registro Español de Trasplante Hepático (RETH) and to validate the DRI and ET-DRI indicators...
