Abstract
The financial impact of liver transplantation has been underexplored. We aimed to identify associations between high financial burden (≥10% annual income spent on out-of-pocket medical costs) and work productivity, financial distress (coping behaviors in response to the financial burden), and financial toxicity (health-related quality of life, HRQOL) among adult recipients of liver transplant. Between June 2021 and May 2022, we surveyed 207 adult recipients of liver transplant across 5 US transplant centers. Financial burden and distress were measured by 25 items adapted from national surveys of cancer survivors. Participants also completed the Work Productivity and Activity Impairment and EQ-5D-5L HRQOL questionnaires. In total, 23% of recipients reported high financial burden which was significantly associated with higher daily activity impairment (32.9% vs. 23.3%, p =0.048). In adjusted analyses, the high financial burden was significantly and independently associated with delayed or foregone medical care (adjusted odds ratio, 3.95; 95% CI, 1.85-8.42) and being unable to afford basic necessities (adjusted odds ratio, 5.12; 95% CI: 1.61-16.37). Recipients experiencing high financial burden had significantly lower self-reported HRQOL as measured by the EQ-5D-5L compared to recipients with low financial burden (67.8 vs. 76.1, p =0.008) and an age-matched and sex-matched US general population (67.8 vs. 79.1, p <0.001). In this multicenter cohort study, nearly 1 in 4 adult recipients of liver transplant experienced a high financial burden, which was significantly associated with delayed or foregone medical care and lower self-reported HRQOL. These findings underscore the need to evaluate and address the financial burden in this population before and after transplantation.

Abstract
Elective transjugular intrahepatic portosystemic shunt (TIPS) placement can worsen cognitive dysfunction in hepatic encephalopathy (HE) patients due to toxins, including possible microbial metabolites, entering the systemic circulation. We conducted untargeted metabolomics on a prospective cohort of 22 patients with cirrhosis undergoing elective TIPS placement and followed them up to one year post TIPS for HE development. Here we suggest that pre-existing intrahepatic shunting predicts HE severity post-TIPS. Bile acid levels decrease in the peripheral vein post-TIPS, and the abundances of three specific conjugated di- and tri-hydroxylated bile acids are inversely correlated with HE grade. Bilirubins and glycerophosphocholines undergo chemical modifications pre- to post-TIPS and based on HE grade. Our results suggest that TIPS-induced metabolome changes can impact HE development, and that pre-existing intrahepatic shunting could be used to predict HE severity post-TIPS.

Abstract
Hepatic encephalopathy (HE) is a common complication of advanced liver disease causing brain dysfunction. This is likely due to the accumulation of unfiltered toxins within the bloodstream. A known risk factor for developing or worsening HE is the placement of a transjugular intrahepatic portosystemic shunt (TIPS), which connects the pre-hepatic and post-hepatic circulation allowing some blood to bypass the dysfunctional liver and decreases portal hypertension. To better understand the pathophysiology of post-TIPS HE, we conducted a multi-center prospective cohort study employing metabolomic analyses on hepatic vein and peripheral vein blood samples from participants with cirrhosis undergoing elective TIPS placement, measuring chemical modifications and changes in concentrations of metabolites resulting from TIPS placement. In doing so, we identified numerous alterations in metabolites, including bile acids, glycerophosphocholines, and bilirubins possibly implicated in the development and severity of HE.

Abstract
Immune checkpoint inhibitors (ICI) have been used to treat hepatocellular carcinoma (HCC) since 2017. The safety of ICIs in the setting of solid organ transplantation remains controversial. When used in the post-transplant setting, ICIs have been associated with high allograft rejection rates, but there are few published reports on the use of ICIs prior to transplant. We present the first reported case of rescue liver re-transplantation after loss of the first allograft due to severe acute rejection with extensive hepatic necrosis in the setting of pre-transplant ICI therapy with the PD-1 inhibitor nivolumab. It is likely that the durable immune response triggered by nivolumab contributes to graft rejection, therefore extreme caution should be taken when using ICIs before transplant until further investigation has been conducted on their safety in the pre-transplant setting.

Abstract
BACKGROUND Fontan associated liver disease (FALD) is attributed to the limitations of the Fontan circulation, resulting in congestive hepatopathy. The technique and outcomes of transjugular liver biopsies (TJLB) in Fontan patients warrant definition as part of a rigorous FALD surveillance program. METHOD Four year review of patients with Fontan physiology who underwent a TJLB during surveillance catheterizations. Biopsy site, technique, histology, angiography, hemodynamics, and complications were reviewed to assess correlation of biopsy scores with simultaneously obtained catheterization hemodynamics. RESULTS 125 patients with a TJLB from 10/1/14 to 5/1/18. Median age 17 years (2-50.5). Technical success 100% (125/125), all samples diagnostic. 17% (21) accessed via the left internal jugular vein, secondary to right IJ occlusion or Heterotaxy syndrome. No patients had superior compartment obstruction preventing transjugular approach. 3.2% complication rate (4/125). Complications were early in the experience, including capsular perforation (2), renal hematoma (1) and hemobilia (1), all without long-term effect and all avoidable. After standardized entry/exit angiography was adopted, no further complications noted. There is a significant correlation between the newly described modified Ishak congestive hepatic fibrosis (ICHF) score with mean Fontan pressure, time from Fontan and cardiac index. CONCLUSIONS TJLB is an alternate method for obtaining critical FALD surveillance data, with lower complication rates that traditional techniques. Vascular anomalies in Fontan physiology appear common and warrant pre-biopsy assessment. There is a significant correlation between biopsy score, time from Fontan, mean Fontan pressure and cardiac index.

Abstract
Single ventricle physiology and palliation via the Fontan operation lead to a series of cardiovascular changes. In addition, organs such as the kidneys and liver have been shown to experience insults and subsequent injury. This has led to routine surveillance of patients. We present findings from a small cohort of patients that was deeply phenotyped to illustrate the need for comprehensive evaluation. A cohort of four Fontan patients with fairly high cardiovascular function was recruited 5–10 years post-Fontan. Patients underwent a rigorous clinical work-up after which a research MRI scan was performed during which (I) data were obtained during exercise to evaluate changes in stroke volume during supine exercise and (II) magnetic resonance angiograms with phase-contrast images were obtained for computational modeling of flows through the Fontan circulation at rest. Clinical measures were consistent with a fairly homogeneous high function cohort (peak oxygen consumption >20 mL/kg/min, robust response to exercise, peak ventilatory efficiency below levels associated with heart failure, MR-derived ejection fraction >50%). Liver evaluation did not reveal clear signs of cirrhosis or extensive fibrosis. However, we observed considerable variability (27–162%) in the increase in stroke index with exercise [100%±64% increase, 53.9±17.4 mL/beat m2 (rest), 101.1±20.7 mL/beat m2, (exercise)]. Computational flow modeling at rest in two patients also showed marked differences in flow distribution and shear stress. We report marked differences in both changes in stroke index during an exercise MRI protocol as well as computational flow patterns at rest suggesting different compensation strategies may be associated with high functioning Fontan patients. The observed heterogeneity illustrates the need for deep phenotyping to capture patient-specific adaptive mechanisms.

Abstract
Modern antiretroviral therapy (ART) extends life expectancy for people living with HIV (PLWH). However, most older PLWH (≥50 years) "aged" with HIV and were exposed to historical HIV care practices and older, more toxic ART. In PLWH with exposure to older and multiple ART regimens, the drug interactions between ART frequently used in treatment-experienced persons and commonly used immunosuppressants remain a significant challenge. However, the advent of newer ART classes (eg, integrase non-strand transfer inhibitors) and more advanced HIV genetic resistance testing may allow optimization of ART regimens with minimal drug interactions. Here, we present a case series of three PLWH whose complicated ART interacted (or was at risk for interacting) with their post-liver transplant immunosuppression. After a review of their proviral DNA resistance testing, they successfully transitioned onto safer integrase non-strand transfer inhibitor-containing ART regimens without viral blips or evidence of organ rejection.

Abstract
Aramchol, an oral stearoyl-coenzyme-A-desaturase-1 inhibitor, has been shown to reduce hepatic fat content in patients with primary nonalcoholic fatty liver disease (NAFLD); however, its effect in patients with human immunodeficiency virus (HIV)-associated NAFLD is unknown. The aramchol for HIV-associated NAFLD and lipodystrophy (ARRIVE) trial was a double-blind, randomized, investigator-initiated, placebo-controlled trial to test the efficacy of 12 weeks of treatment with aramchol versus placebo in HIV-associated NAFLD. Fifty patients with HIV-associated NAFLD, defined by magnetic resonance imaging (MRI)-proton density fat fraction (PDFF) ≥5%, were randomized to receive either aramchol 600 mg daily (n = 25) or placebo (n = 25) for 12 weeks. The primary endpoint was a change in hepatic fat as measured by MRI-PDFF in colocalized regions of interest. Secondary endpoints included changes in liver stiffness using magnetic resonance elastography (MRE) and vibration-controlled transient elastography (VCTE), and exploratory endpoints included changes in total-body fat and muscle depots on dual-energy X-ray absorptiometry (DXA), whole-body MRI, and cardiac MRI. The mean (± standard deviation) of age and body mass index were 48.2 ± 10.3 years and 30.7 ± 4.6 kg/m2 , respectively. There was no difference in the reduction in mean MRI-PDFF between the aramchol group at -1.3% (baseline MRI-PDFF 15.6% versus end-of-treatment MRI-PDFF 14.4%, P = 0.24) and the placebo group at -1.4% (baseline MRI-PDFF 13.3% versus end-of-treatment MRI-PDFF 11.9%, P = 0.26). There was no difference in the relative decline in mean MRI-PDFF between the aramchol and placebo groups (6.8% versus 1.1%, P = 0.68). There were no differences in MRE-derived and VCTE-derived liver stiffness and whole-body (fat and muscle) composition analysis by MRI or DXA. Compared to baseline, end-of-treatment aminotransferases were lower in the aramchol group but not in the placebo arm. There were no significant adverse events. Conclusion: Aramchol, over a 12-week period, did not reduce hepatic fat or change body fat and muscle composition by using MRI-based assessment in patients with HIV-associated NAFLD (clinicaltrials.gov ID:NCT02684591).

Abstract
BACKGROUND The risk of advanced fibrosis in first-degree relatives of patients with nonalcoholic fatty liver disease and cirrhosis (NAFLD-cirrhosis) is unknown and needs to be systematically quantified. We aimed to prospectively assess the risk of advanced fibrosis in first-degree relatives of probands with NAFLD-cirrhosis. METHODS This is a cross-sectional analysis of a prospective cohort of 26 probands with NAFLD-cirrhosis and 39 first-degree relatives. The control population included 69 community-dwelling twin, sib-sib, or parent-offspring pairs (n = 138), comprising 69 individuals randomly ascertained to be without evidence of NAFLD and 69 of their first-degree relatives. The primary outcome was presence of advanced fibrosis (stage 3 or 4 fibrosis). NAFLD was assessed clinically and quantified by MRI proton density fat fraction (MRI-PDFF). Advanced fibrosis was diagnosed by liver stiffness greater than 3.63 kPa using magnetic resonance elastography (MRE). RESULTS The prevalence of advanced fibrosis in first-degree relatives of probands with NAFLD-cirrhosis was significantly higher than that in the control population (17.9% vs. 1.4%, P = 0.0032). Compared with controls, the odds of advanced fibrosis among the first-degree relatives of probands with NAFLD-cirrhosis were odds ratio 14.9 (95% CI, 1.8-126.0, P = 0.0133). Even after multivariable adjustment by age, sex, Hispanic ethnicity, BMI, and diabetes status, the risk of advanced fibrosis remained both statistically and clinically significant (multivariable-adjusted odds ratio 12.5; 95% CI, 1.1-146.1, P = 0.0438). CONCLUSION Using a well-phenotyped familial cohort, we demonstrated that first-degree relatives of probands with NAFLD-cirrhosis have a 12 times higher risk of advanced fibrosis. Advanced fibrosis screening may be considered in first-degree relatives of NAFLD-cirrhosis patients. TRIAL REGISTRATION UCSD IRB 140084.

Abstract
Mortality rates on the liver transplant waiting list are increasing. The shortage of organs has resulted in higher utilization of extended criteria donors (ECDs), with centers pushing the limits of what is acceptable for transplantation. Donor quality is more appropriately represented as a continuum of risk, and careful selection and matching of ECD grafts with recipients may lead to excellent outcomes. Although there is no precise definition for what constitutes an ECD liver, this review focuses on frequently cited characteristics, including donor age, steatosis, donation after cardiac death, and donors with increased risk of disease transmission.

Abstract
BACKGROUND There are limited data regarding the clinical, biochemical and liver histological characteristics of patients with HIV-associated nonalcoholic fatty liver disease (NAFLD), and whether this entity differs in presentation and severity from primary NAFLD AIM: To examine the clinical and histological differences between HIV-associated NAFLD and primary NAFLD. METHODS This is a cross-sectional, case-control study comparing patients with HIV-associated NAFLD vs. patients with primary NAFLD. HIV-infected patients were identified from a database of consecutive liver biopsies performed at the University of California at San Diego, over a 13-year period. HIV-infected patients with biopsy-proven NAFLD were selected as cases, after exclusion of other causes of liver disease and hepatic steatosis. Age-sex-matched controls with biopsy-proven primary NAFLD were randomly identified from the same pathology database. All biopsies underwent a standardised, detailed, histological research evaluation by a liver pathologist who was blinded to clinical and case-control status. RESULTS Compared to age-sex-matched patients with primary NAFLD (n = 33), patients with HIV-associated NAFLD (n = 33) had significantly higher mean aspartate aminotransferase (P < 0.001), alanine aminotransferase (P < 0.001), alkaline phosphatase (P = 0.003) and serum triglycerides (P = 0.024). Similarly, compared to age-sex-matched primary NAFLD, patients with HIV-associated NAFLD had significantly higher rates of definite steatohepatitis (37% vs. 63%, P = 0.04), and more features of liver injury, including lobular inflammation (<0.001) and acidophil bodies (<0.001). CONCLUSION Compared to age-sex-matched primary NAFLD, HIV-associated NAFLD has increased severity of liver disease and a higher prevalence of NASH.

Abstract
Hepatitis B virus (HBV) infects over 2 billion people worldwide, with approximately 360 million chronically infected. It results in substantial morbidity and mortality, with an estimated 600,000 deaths per year. In endemic areas, mother to child transmission (MTCT) is the most important source of new infections, but even in areas with low endemicity, over 1/3 of infections can still be attributed to this route. Although very effective active-passive immunoprophylaxis with hepatitis B immune globulin (HBIG) and HBV vaccine is available, even with full compliance, failure can be seen in highly viremic mothers who are positive for hepatitis B e antigen. Potential means of reducing the risk of MTCT include nucleotide/nucleoside antiviral agents, interferon in very select cases, and mode of delivery. Determining the optimal therapy and its timing, and preventing both obstetric and liver related complications remains a challenge, but is also an important opportunity to reduce chronic hepatitis B infection. In this review, we provide an overview of issues associated with hepatitis B and its treatment during pregnancy, and suggest an algorithm for management.
