Outcomes of Liver Transplantation Among Older Recipients With Nonalcoholic Steatohepatitis in a Large Multicenter US Cohort: the Re-Evaluating Age Limits in Transplantation Consortium.

The liver transplantation (LT) population is aging, with the need for transplant being driven by the growing prevalence of nonalcoholic steatohepatitis (NASH). Older LT recipients with NASH may be at an increased risk for adverse outcomes after LT. Our objective is to characterize outcomes in these recipients in a large multicenter cohort.

Intensive Care Management of Acute Liver Failure: Considerations While Awaiting Liver Transplantation.

Acute liver failure is a unique clinical phenomenon characterized by abrupt deterioration in liver function and altered mentation. The development of high-grade encephalopathy and multisystem organ dysfunction herald poor prognosis. Etiologic-specific treatments and supportive measures are routinely employed; however, liver transplantation remains the only chance for cure in those who do not spontaneously recover.

Lymphovascular invasion on explant is associated with presenting tumor characteristics and not direct acting antiviral utilization in hepatitis C candidates undergoing liver transplantation.

Aim Of The Study: Utilization of direct acting antiviral (DAA) therapy in candidates with well-compensated hepatitis C virus (HCV) cirrhosis and hepatocellular carcinoma (HCC) accruing end stage liver disease (MELD) exception points is highly variable among transplant centers based on center location, local organ procurement dynamics, HCV(+) organ availability, and patient preference. The association between DAA utilization prior to transplant and incidence of lymphovascular invasion on explant is unknown.

Material And Methods: Retrospective evaluation from 2013-2017 of patients on a liver transplant (LT) waitlist with HCV-related cirrhosis, MELD-Na < 15, and HCC (within T2/Milan criteria).

Utility of Transjugular Intrahepatic Portosystemic Shunt Placement for Maintaining Portal Vein Patency in Candidates on Wait Lists Who Develop Thrombus.

Objectives: Although no longer a contraindication to liver transplant, portal vein thrombosis may lead to longer operative time and complexities in venous reconstruction. Strategies to maintain preoperative patency include systemic anticoagulation and/or transjugular intrahepatic portosystemic shunt placement. The former may not be ideal in cirrhotic patients prone to luminal gastrointestinal tract bleeding, and factors that predict improvements in portal vein thrombosis with the latter have not been well defined.

Liver transplantation for hepatocellular carcinoma: Management after the transplant.

Hepatocellular carcinoma (HCC) is an increasingly common indication for liver transplantation (LT) in the United States and in many parts of the world. In the last decade, significant work has been done to better understand how to risk stratify LT candidates for recurrence of HCC following transplant using a combination of biomarker and imaging findings. However, despite the high frequency of HCC in the LT population, guidance regarding posttransplant management is lacking.

Immune Reconstitution Syndrome with Initiation of Treatment of HBV/HIV Co-infection: Activity Flare associated with E antigen Seroconversion.

Immune reconstitution syndrome is a recognized complication with initiation of highly active antiretroviral therapy for acquired immune deficiency syndrome patients co-infected with hepatitis B. Hepatitis B flares are seen in 20%-25% of patients after initiation of highly active antiretroviral therapy, an estimated 1%-5% of whom develop clinical hepatitis. We present a case of highly active antiretroviral therapy initiation for HIV that led to a flare of HBV activity despite antiviral therapy directed towards both.

Real-Time Ultrasound-Guided Paracentesis by Radiologists: Near Zero Risk of Hemorrhage without Correction of Coagulopathy.

Purpose: To evaluate the rate and risk factors for hemorrhage in patients undergoing real-time, ultrasound-guided paracentesis by radiologists without correction of coagulopathy.

Materials And Methods: This was a retrospective study of all patients who underwent real-time, ultrasound-guided paracentesis at a single institution over a 2-year period. In total, 3116 paracentesis procedures were performed: 757 (24%) inpatients and 2,359 (76%) outpatients.

Race and Gradient Difference Are Associated with Increased Risk of Hepatic Encephalopathy Hospital Admission After Transjugular Intrahepatic Portosystemic Shunt Placement.

Background/aims: Hepatic encephalopathy (HE) is a well-recognized complication of transjugular intrahepatic portosystemic shunt (TIPS) placement. The aim of this investigation was to evaluate incidence and predictors of post-TIPS HE necessitating hospital admission in a non-clinical trial setting.

Methods: We performed a retrospective cohort study identifying 273 consecutive patients undergoing TIPS from 2010 to 2015 for any indication; 210 met inclusion/exclusion criteria.

Rapid reversal of colonic pneumatosis with restoration of mesenteric arterial supply.

Pneumatosis cystoides intestinalis (PCI) is characterized by gas-filled cystic lesions within the wall of the large intestine and presents along a spectrum of clinical severity ranging from benign to life threatening. Etiopathogenesis is multifactorial and postulated to result from either mechanical or bacterial causes. In this report, we present a patient with chronic abdominal pain evaluated with colonoscopy revealing segmental PCI isolated to the distal colon.

Refractory Hepatic Encephalopathy After Elective Transjugular Intrahepatic Portosystemic Shunt: Risk Factors and Outcomes with Revision.

Background And Aims: Hepatic encephalopathy (HE) is a common complication of elective transjugular intrahepatic portosystemic shunt (TIPS) placement and is often successfully medically managed. Risk factors for refractory hepatic encephalopathy (RHE) necessitating revision of TIPS are not well defined. We evaluated the incidence, predictors, and outcomes of post-TIPS RHE necessitating TIPS revision.

Predictors of intermediate-term survival with destination locoregional therapy of hepatocellular cancer in patients either ineligible or unwilling for liver transplantation.

Intra-arterial or percutaneous locoregional therapies (LRT) are often employed to maintain potential liver transplant (LT) recipients with hepatocellular carcinoma (HCC) within T2/Milan criteria. Predictors of survival when LRT is used as destination therapy in those who are either ineligible or unwilling for LT remain poorly defined. We evaluated predictors of 3-year survival with destination LRT in a population of cirrhotic patients diagnosed with HCC, presenting within T2 criteria, and either ineligible or unwilling for LT.

Rapid Development of De Novo Thoracic Aneurysm After Liver Transplant.

The development of aortic aneurysms in post-transplant patients is a rare but potentially lethal problem. De novo aortic aneurysm formation and rapid growth are postulated to result from an imbalance between pro- and anti-inflammatory vascular endothelial factors after transplant. Here, we present a case of de novo thoracic aneurysm formation within 2 months of orthotopic liver transplant.

Profiling Neutrophil-to-Lymphocyte Ratio Changes in Response to Nucleoside Analog Therapy for Chronic Hepatitis B Infection.

Background/aim: The neutrophil-lymphocyte ratio (NLR) has gained attention as an index of inflammation in patients with chronic hepatitis B virus (HBV); however, changes with nucleoside analog therapy require investigation.

Patients And Methods: We carried out a retrospective study identifying monoinfected HBV patients initiated on therapy with NLR follow-up over 1 year. Biochemistries recorded at treatment initiation and 1 year included alanine aminotransferase (ALT), Model for End Stage Liver Disease (MELD) score, and NLR.

Liver Transplantation in the Obese Cirrhotic Patient.

Despite the rapidly increasing prevalence of obesity in the transplant population, the optimal management of obese liver transplant candidates remains undefined. Setting strict body mass index cutoffs for transplant candidacy remains controversial, with limited data to guide this practice. Body mass index is an imperfect measure of surgical risk in this population, partly due to volume overload and variable visceral adiposity.

25-Vitamin D levels in chronic hepatitis C infection: association with cirrhosis and sustained virologic response.

Background: Low serum 25-Vitamin D levels are associated with advanced fibrosis in hepatitis C infection. Vitamin D supplementation has been hypothesized to augment response rates to interferon-based therapy. To date, no investigation has evaluated vitamin D levels during direct-acting antiviral therapy.

Genotype specific peripheral lipid profile changes with hepatitis C therapy.

Aim: To evaluate magnitude/direction of changes in peripheral lipid profiles in patients undergoing direct acting therapy for hepatitis C by genotype.

Methods: Mono-infected patients with hepatitis C were treated with guideline-based DAAs at a university-based liver clinic. Patient characteristics and laboratory values were collected before and after the treatment period.

Primary Biliary Cholangitis: Disease Pathogenesis and Implications for Established and Novel Therapeutics.

Primary Biliary Cholangitis is a progressive, autoimmune cholestatic liver disorder. Cholestasis with disease progression may lead to dyslipidemia, osteodystrophy and fat-soluble vitamin deficiency. Portal hypertension may develop prior to advanced stages of fibrosis.

Pretransplant Factors and Associations with Postoperative Respiratory Failure, ICU Length of Stay, and Short-Term Survival after Liver Transplantation in a High MELD Population.

Changes in distribution policies have increased median MELD at transplant with recipients requiring increasing intensive care perioperatively. We aimed to evaluate association of preoperative variables with postoperative respiratory failure (PRF)/increased intensive care unit length of stay (ICU LOS)/short-term survival in a high MELD cohort undergoing liver transplant (LT). Retrospective analysis identified cases of PRF and increased ICU LOS with recipient, donor, and surgical variables examined.
