The incidence of obesity is rising exponentially. This is having a direct impact on liver transplantation due to an increase in NAFLD disease and numbers of overweight and obese patients requiring transplantation. There is now evidence suggesting that obesity has a negative impact on both graft and patient survival. There remains an imbalance between number of donors available and patients requiring transplantation. We therefore need to ensure we make the best use of the organs available, optimizing graft and patient survival in those fortunate enough to receive an organ...

BACKGROUND: The obesity epidemic has significantly increased the incidence and severity of hepatic steatosis in liver surgery patients and liver donors, potentially impacting postoperative liver regeneration and function. Development of a non-invasive means to quantify hepatic steatosis would facilitate selection of candidates for liver resection and transplant donation. METHODS: An IRB-approved protocol prospectively enrolled 28 patients with liver tumors requiring hepatic resection...

INTRODUCTION: Biliary complications occur in 10-30% of liver transplants. The aim of this study was to compare the incidence of these complications in liver transplants when the T-tube was or was not used during the biliary anastomosis. MATERIAL AND METHODS: Analysis of 2 groups of patients undergoing liver transplantation between 2008 and 2012. Patients were divided considering if the T-tube was used (G1) or if it was not (G2). We sought explanatory models of the occurrence of biliary complications by logistic regression, including the variables identified in the univariate analysis...

BACKGROUND: Despite substantial progress toward measles control are making in China, measles outbreaks in immunocompromised population still pose a challenge to interrupt endemic transmission. This study aimed to investigate the features of measles in pediatric hematology and oncology patients and explore the reasons behind the outbreak. METHODS: We collected demographic, epidemiological, and clinical data of immunocompromised measles children. All suspected measles cases were laboratory-confirmed based on the presence of measles IgM and/or identification of measles RNA...

In liver transplant (LT) recipients, the cause of graft dysfunction in pregnancy is often difficult to ascertain. Moreover, a liver biopsy in late pregnancy is often avoided as a consequence of patient and physician factors. Management of graft dysfunction can be difficult in this setting. We report a 30-year-old female LT recipient who developed acutely deranged liver biochemistry during the third trimester of her first pregnancy. At 29 weeks gestation, her liver function test (LFT) became abnormal; AST peaked at 978 IU/L (normal range 10-50), GGT 25 IU/L (normal range 1-55), bilirubin 1...

BACKGROUND The recipient's pattern of hepatic veins (HVs) drainage into the inferior vena cava (IVC) (drainage pattern, for short) may influence outflow reconstruction and thus hepatic venous outflow obstruction (HVOO) in piggyback liver transplantation (PBLT). However, no previous study has investigated this association. MATERIAL AND METHODS A retrospective analysis of 202 PBLT (2000-2016) was conducted. Based on drainage patterns, the patients were divided into Group A (common trunk of left and middle HVs), Group B (common trunk of right and middle HVs), and Group C (common trunk of 3 HVs)...

BACKGROUND: We prospectively identified B-lines in patients undergoing ultrasound examinations following liver transplants who also had a chest x-ray (CXR) and/or chest CT scan on the same day to determine if an association between the presence of B-lines s from the thorax on ultrasound images correlates with the presence of pulmonary abnormalities on chest radiographs. MATERIALS AND METHODS: Following IRB approval, patients undergoing routine postoperative liver transplant ultrasound examinations and a CXR and/or CT scan on the same day between 1/1/2015 through 7/1/2016 were prospectively identified...

Non-alcoholic fatty liver disease (NAFLD), the most common liver disease, is characterized by accumulation of fat (>5% of the liver tissue), in the absence of alcohol abuse or other chronic liver diseases. It is closely related to the epidemic of obesity, metabolic syndrome or type 2 diabetes mellitus (T2DM). NAFLD can cause liver inflammation and progress to non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis or hepatocellular cancer (HCC). Nevertheless, cardiovascular disease (CVD) is the most common cause of death in NAFLD/NASH patients...

Hepatic angiosarcoma is a rare, aggressive, malignant neoplasm with fewer than 50 cases reported in children. Prognosis is poor, with a minority surviving beyond 2 years after diagnosis. We report eight cases of pediatric hepatic angiosarcoma, diagnosed at a mean age of 3 years. Seven were initially diagnosed with an infantile hepatic hemangioendothelioma (IHHE) or hemangioma and the eighth with a "vascular tumor." Two patients, who received liver transplant, survived. We suggest hepatic hemangiomas can rarely transform into angiosarcomas and a subset of IHHEs (Type II) are actually a low-grade form of angiosarcoma rather than a benign lesion...

BACKGROUND: The natural history of ulcerative colitis (UC) after liver transplantation (LT) for primary sclerosing cholangitis (PSC) remains ill defined. This study aimed to evaluate the course of UC after LT for PSC. METHODS: The course of UC, including the clinical colitis severity index, was evaluated in patients with concomitant PSC and UC who received LT for PSC-induced end-stage liver disease. A total of 167 (55.4%) patients with PSC had concurrent inflammatory bowel disease (IBD)...

BACKGROUND AND AIM: Gastric antral vascular ectasia (GAVE) is an important cause of upper gastrointestinal bleeding and anemia in patients with cirrhosis. The aim of our study was to evaluate the effect of orthotopic liver transplantation (OLT) on GAVE and associated anemia. PATIENTS AND METHODS: We performed a chart review and identified all cirrhotic patients with GAVE who underwent OLT at the University Of Alabama at Birmingham between 2005 and 2013. Population's demographics, etiology of cirrhosis, comorbidities, presentation and treatment modalities of GAVE, endoscopic and histopathologic reports, hemoglobin values before and after transplant, and immunosuppressive regimens were collected...

We investigate the possibility that patients with hepatocellular carcinoma (HCC) listed for liver transplant with tumors just outside Stage T2 size criteria may be inaccurately reported as just meeting the tumor size criteria for transplant. The UNOS/STAR database identified 12,958 patients listed for liver transplants with HCC exception points from 2006-2013, 9,168 of whom were listed with one tumor. A logistic power peak function was fitted to the single-tumor size histogram, with the fitted values representing unbiased expected values...

REVIEW
Katayoun Behnam Sani, Birgit Sawitzki
Ever since its first application in clinical medicine, scientists have urged to induce tolerance towards foreign allogeneic transplants and thus avoid rejection by the recipient's immune system. This would circumvent chronic use of immunosuppressive drugs (IS) and thus avoid development of IS-induced side effects, which are contributing to the still unsatisfactory long-term graft and patient survival after solid organ transplantation. Although manifold strategies of tolerance induction have been described in preclinical models, only three therapeutic approaches have been successfully utilized in a still small number of patients...

Min-Jun Wang, Fei Chen, Joseph T Y Lau, Yi-Ping Hu
A characteristic cellular feature of the mammalian liver is the progressive polyploidization of the hepatocytes, where individual cells acquire more than two sets of chromosomes. Polyploidization results from cytokinesis failure that takes place progressively during the course of postnatal development. The proportion of polyploidy also increases with the aging process or with cellular stress such as surgical resection, toxic stimulation, metabolic overload, or oxidative damage, to involve as much as 90% of the hepatocytes in mice and 40% in humans...

OBJECTIVE: To compare and analyze how allometrically- and linearly-scaled daily doses of cyclosporine could affect the therapeutic drug monitoring concentrations when applied to 8 infants with liver transplants. MATERIALS AND METHODS: Eight infants who underwent liver transplantations were put on twice-daily oral cyclosporine immunosuppressive regimens. After starting therapy, the adjustments of individual daily doses were determined by using therapeutic monitoring of plasma cyclosporine levels by measuring trough concentrations (C0) and concentrations at 2 hours after drug administration (C2)...

BACKGROUND: Primary biliary cholangitis (PBC), formerly known as primary biliary cirrhosis, is a chronic cholestatic liver disease characterized by an immune mediated destruction of intrahepatic bile ducts. Ursodeoxycholic acid (UDCA) has been the primary medication for the treatment of PBC, resulting in improved liver tests, resolution of symptoms and increased transplant free survival. However, not all patients respond to UDCA. The aim of this systematic review is to provide an evidence based assessment of the medications that have been studied in patients who are refractory to UDCA...
