BACKGROUND: Biliary strictures (BS) are a common complication of liver transplantation. The standard treatment is sequential insertion of increasing numbers of plastic stents by endoscopic retrograde cholangiopancreatography (ERCP). Despite high success rates, some strictures fail to resolve and require surgery as definitive treatment. GOALS: To identify predictors of response or failure of standard endoscopic treatment, allowing earlier referral to alternative modalities when needed and avoiding unnecessary procedures...

AIM: Congenital portosistemic shunt (CPSS) is an uncommon condition that can cause serious complications such as encephalopathy and liver tumors at risk of malignant degeneration. Occlusion of the shunt by surgery or interventional radiology can prevent and even improve such complications. In some cases, liver transplantation is the only curative option. We describe our experience with this condition. PATIENTS AND METHODS: Between 1992 and 2013, eight children (four male and four female) were diagnosed with CPSS (four extrahepatic and four intrahepatic) in our center, of which seven were diagnosed after 2007...

Activated hepatic stellate cells express cytoplasmic ASMA prior to secreting collagen and consequent liver fibrosis. We hypothesized that quantifying ASMA could predict severity of future fibrosis after LT. For this, 32 pairs of protocol biopsies, that is, "baseline" and "follow-up" biopsies taken at 1- to 2-year intervals from 18 stable pediatric LT recipients, transplanted between 2006 and 2012 were selected. Morphometric quantification of "ASMA-positive area percentage" was performed on the baseline biopsy...

HBoV is an emergent virus, which is frequently detected as a co-infective agent. However, it can cause disease on its own. It is associated with respiratory and diarrhoeal illness in children and adults, whether immunocompetent or immunocompromised. We report HBoV infection in a child post-liver transplantation, who presented with persistent fever and mild tachypnea, 3 weeks after a successful transplant. She recovered spontaneously with no graft dysfunction.

BACKGROUND: We related hepatic gene and serum expression of matrix metalloproteinases (MMP) and their tissue inhibitors (TIMP) to liver histology in pediatric LT recipients. METHODS: Liver biopsies and serum samples were obtained from 52 patients 10.6 years post-LT and age-matched controls for analyses of MMPs and TIMPs. RESULTS: Patients with fibrosis had significantly higher hepatic gene expression of MMP-2, MMP-9, MMP-14, TIMP-1 and TIMP-2 than patients without...

Liver segmentation from abdominal computed tomography (CT) volumes is extremely important for computer-aided liver disease diagnosis and surgical planning of liver transplantation. Due to ambiguous edges, tissue adhesion, and variation in liver intensity and shape across patients, accurate liver segmentation is a challenging task. In this paper, we present an efficient semi-automatic method using intensity, local context, and spatial correlation of adjacent slices for the segmentation of healthy liver regions in CT volumes...

BACKGROUND: The incidence of hepatocellular carcinoma has doubled over the past 2 decades, becoming the fifth most common cancer worldwide. Orthotopic liver transplant is the gold standard treatment for those with hepatocellular carcinoma meeting eligibility criteria, although recurrence rates of hepatocellular carcinoma after orthotopic liver transplant still remain an understudied obstacle. METHODS: We performed a single-center, retrospective, longitudinal study with the aim of determining the predominant baseline and follow-up variables associated with hepatocellular carcinoma recurrence...

BACKGROUND: Hepatitis delta is the most severe form of viral hepatitis. Pegylated interferon alfa (PEG- IFNα) is effective in only 25-30% of patients and is associated with frequent side effects. The aim of this study was to analyze the clinical long-term outcome of hepatitis delta in relation to different antiviral treatment strategies. METHODS: We studied 136 anti-HDV-positive patients who were followed for at least 6 months in a retrospective single-center cohort (mean time of follow up 5...

To investigate the potential oncogene promoting recurrence of hepatocellular carcinoma (HCC) following liver transplantation (LT), throughput RNA sequencing was performed in a subgroup of HCC patients. The up-regulated FAM83D in HCC tissues was found and further verified in 150 patients by real-time PCR and immunohistochemistry. FAM83D overexpression significantly correlated with high HCC recurrence rate following LT and poor HCC characteristics such as high AFP, poor differentiation. Of cancer stem cells (CSCs) markers, CD44 expression was effectively suppressed when FAM83D was knocked down by siRNA...

PURPOSE: This study aimed to evaluate the accuracy of gadoxetic acid-enhanced magnetic resonance imaging (Gd-EOB-MRI) in predicting eligibility for liver transplantation in patients with hepatocellular carcinoma (HCC) based on Milan criteria (MC). MATERIALS AND METHODS: We reviewed Gd-EOB-MRI of 44 patients who underwent liver transplantation for HCC with cirrhosis for the presence/size of HCCs, vascular invasion, and transplant eligibility based on MC. Hepatocellular carcinoma was diagnosed based on conventional radiological hallmarks (arterial enhancement and washout) or the modified criteria...

Chronic Hepatitis C is a major public health problem. The chronicity of the Hepatitis C can lead to advanced liver disease, cirrhosis and even hepatocellular carcinoma. Chronic hepatitis C is the leading indication of for liver transplantation in the United States. Since the introduction of directly acting antiviral agents (DAAs), there have been there have been dramatic advances in treatment of hepatitis C in terms of tolerability, duration of therapy with significant increases in the rates of sustained virology response (SVR)...

BACKGROUND Ischemic type biliary lesions (ITBL) is a troublesome complication after liver transplantation. Little is known about its pathogenesis and there is particularly little data about morphological alterations. Prolonged warm and cold ischemia time and reduced hepatic arterial perfusion are risk factors leading to ITBL. There are only a few animal models described in literature. Therefore, we examined the effects of 3 h of hepatic artery ischemia-reperfusion (3 h I/R) and hepatic arterial ligation (HAL), both combined with ligation of the peribiliary plexus (PBP)...

Rigler sign is a double wall sign suggesting pneumoperitoneum and intestinal perforation, and it needs emergency surgical treatment. Early diagnosis of intestinal perforation by clinical symptoms, presence of Rigler sign in abdominal radiography, and then early surgical treatment can reduce mortality. Here, we report a patient with Crigler-Najjar syndrome who underwent liver transplant and then developed posttransplant lymphoproliferative disease and received chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab...

OBJECTIVE AND IMPORTANCE: Transplantation-mediated alloimmune thrombocytopenia (TMAT) occurs when leukocytes transferred in a donor organ from a patient with immune thrombocytopenia (ITP), mount a response against recipient platelets. We present the first fatal case of TMAT following liver transplantation and review its aetiology and treatment. CLINICAL PRESENTATION: The liver donor had ITP and died from an intracranial haemorrhage. The recipient platelet count fell to 2 × 10(9)/l on post-operative day 2...

BACKGROUND: Dendritic cells (DCs) and regulatory T (Treg) cells are crucial for inducing immune tolerance. However, the suppressive function of infused Treg cells and immature DCs (imDCs) following solid organ transplantation remains unclear. METHODS: ImDCs derived from DA-donor rats and Treg cells isolated from spleens of Lewis rats were prepared. A heterotopic liver transplantation model was established to examine the immune tolerance effects of infusion of Treg-imDCs, imDCs and Treg cells individually...

NAFLD is a common condition linked to obesity, type 2 diabetes, and metabolic syndrome. Simple hepatic steatosis is a risk factor for inflammatory reactions in the liver (NASH), which may lead to cirrhosis. While the mechanism is unclear, NAFLD and NASH are associated with panhypopituitarism, which in the pediatric population often results from craniopharyngioma or pituitary adenoma and the sequelae of treatment, causing hypothyroidism, adrenal insufficiency, hypogonadotropic hypogonadism, and GH deficiency...

Portal hypertension secondary to portal vein obstruction following liver transplant occurs in 5%-10% of children. Jejunal varices are uncommon in this group. We present a case series of children with significant GI blood loss, negative upper endoscopy, and jejunal varices detected by CE. Case series of patients who had CE for chronic GI blood loss following liver transplantation. Three patients who had their initial transplants at a median age of 7 months were identified at our institution presenting at a median age of 8 years (range 7-16 years) with a median Hgb of 2...
