- Abstract
Background & Aims: Bulevirtide (BLV), a first-in-class entry inhibitor, is approved in Europe for the treatment of chronic hepatitis delta (CHD). BLV monotherapy was superior to delayed treatment at week (W) 48, the primary efficacy endpoint, in the MYR301 study (NCT03852719). Here, we assessed if continued BLV therapy until W96 would improve virologic and biochemical response rates, particularly among patients who did not achieve virologic response at W24., Methods: In this ongoing, open-label, randomized phase III study, patients with CHD (N = 150) were randomized (1:1:1) to treatment with BLV 2 mg/day (n = 49) or 10 mg/day (n = 50), each for 144 weeks, or to delayed treatment for 48 weeks followed by BLV 10 mg/day for 96 weeks (n = 51). Combined response was defined as undetectable hepatitis delta virus (HDV) RNA or a decrease in HDV RNA by ≥2 log
10 IU/ml from baseline and alanine aminotransferase (ALT) normalization. Other endpoints included virologic response, ALT normalization, and change in HDV RNA., Results: Of 150 patients, 143 (95%) completed 96 weeks of the study. Efficacy responses were maintained and/or improved between W48 and W96, with similar combined, virologic, and biochemical response rates between BLV 2 and 10 mg. Of the patients with a suboptimal early virologic response at W24, 43% of non-responders and 82% of partial responders achieved virologic response at W96. Biochemical improvement often occurred independently of virologic response. Adverse events were mostly mild, with no serious adverse events related to BLV., Conclusions: Virologic and biochemical responses were maintained and/or increased with longer term BLV therapy, including in those with suboptimal early virologic response. BLV monotherapy for CHD was safe and well tolerated through W96., Impact and Implications: In July 2023, bulevirtide was fully approved for the treatment of chronic hepatitis delta (CHD) in Europe based on clinical study results from up to 48 weeks of treatment. Understanding the efficacy and safety of bulevirtide over the longer term is important for healthcare providers. In this analysis, we demonstrate that bulevirtide monotherapy for 96 weeks in patients with CHD was associated with continued improvements in combined, virologic, and biochemical responses as well as liver stiffness from week 48 at both the 2 mg and 10 mg doses. Patients with suboptimal virologic responses to bulevirtide at week 24 also benefited from continued therapy, with the majority achieving virologic response or biochemical improvement by week 96., Gov Identifier: NCT03852719., (Copyright © 2024 The Authors.

- Abstract
Background: In a phase 3 trial, bulevirtide monotherapy led to a virologic response in patients with chronic hepatitis D. Pegylated interferon (peginterferon) alfa-2a is recommended by guidelines as an off-label treatment for this disease. The role of combination therapy with bulevirtide and peginterferon alfa-2a, particularly with regard to finite treatment, is unclear., Methods: In this phase 2b, open-label trial, we randomly assigned patients to receive peginterferon alfa-2a alone (180 μg per week) for 48 weeks; bulevirtide at a daily dose of 2 mg or 10 mg plus peginterferon alfa-2a (180 μg per week) for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks; or bulevirtide at a daily dose of 10 mg alone for 96 weeks. All the patients were followed for 48 weeks after the end of treatment. The primary end point was an undetectable level of hepatitis D virus (HDV) RNA at 24 weeks after the end of treatment. The primary comparison was between the 10-mg bulevirtide plus peginterferon alfa-2a group and the 10-mg bulevirtide monotherapy group., Results: A total of 24 patients received peginterferon alfa-2a alone, 50 received 2 mg and 50 received 10 mg of bulevirtide plus peginterferon alfa-2a, and 50 received 10 mg of bulevirtide monotherapy. At 24 weeks after the end of treatment, HDV RNA was undetectable in 17% of the patients in the peginterferon alfa-2a group, in 32% of those in the 2-mg bulevirtide plus peginterferon alfa-2a group, in 46% of those in the 10-mg bulevirtide plus peginterferon alfa-2a group, and in 12% of those in the 10-mg bulevirtide group. For the primary comparison, the between-group difference was 34 percentage points (95% confidence interval, 15 to 50; P<0.001). At 48 weeks after the end of treatment, HDV RNA was undetectable in 25% of the patients in the peginterferon alfa-2a group, in 26% of those in the 2-mg bulevirtide plus peginterferon alfa-2a group, in 46% of those in the 10-mg bulevirtide plus peginterferon alfa-2a group, and in 12% of those in the 10-mg bulevirtide group. The most frequent adverse events were leukopenia, neutropenia, and thrombocytopenia. The majority of adverse events were of grade 1 or 2 in severity., Conclusions: The combination of 10-mg bulevirtide plus peginterferon alfa-2a was superior to bulevirtide monotherapy with regard to an undetectable HDV RNA level at 24 weeks after the end of treatment.

- Abstract
Background: Noninvasive tests (NITs) have been proposed as an alternative to liver biopsy for diagnosing liver cirrhosis. The evidence of NIT performance in patients with chronic hepatitis D (CHD) is limited., Aims: To evaluate the diagnostic performance of liver stiffness measurement (LSM) and other NITs in CHD patients., Methods: We evaluated the diagnostic performance of LSM by transient elastography for the detection of liver cirrhosis in a retrospective, multicentre cohort of 144 CHD patients with paired (±6 months) LSM and liver biopsies., Results: Cirrhosis was diagnosed histologically in 22 patients (15.3%). Mean LSM was significantly higher in patients with cirrhosis compared to those without fibrosis (23.4 vs 10.2 kPa, p < 0.0001) or with intermediate fibrosis (23.4 vs 13.5 kPa, p < 0.0001). In the detection of liver cirrhosis, LSM was superior to other NITs (AUROCs: 0.89 [LSM], 0.87 [D4FS], 0.74 [APRI], 0.73 [FIB-4], and 0.69 [AAR]). The optimal cut-off for identifying patients with liver cirrhosis was ≥15.2 kPa (Se 91%, Sp 84%, PPV 50%, NPV 98%). The ideal cut-off for diagnosing non-advanced liver fibrosis (Metavir ≤2) was <10.2 kPa (Se 55%, Sp 86%, PPV 90%, NPV 45%), correctly identifying 90% of patients. Data were validated in an independent cohort of 132 CHD patients., Conclusions: LSM is a useful tool for identifying patients at risk for liver cirrhosis and is superior to other NITs. The cut-offs of <10.2 and < 15.2 kPa reliably diagnose non-advanced liver fibrosis and exclude cirrhosis in the majority of patients. However, LSM cannot completely replace liver biopsy in CHD patients., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Chronic hepatitis D infection results in the most severe form of chronic viral hepatitis but currently lacks effective treatment options. Therapy with pegylated interferon alpha is recommended for finite treatment duration by major liver societies. Still, it is plagued by low rates of sustained virologic response (SVR) and frequent relapses even if SVR is achieved. Recently, a wave of investigational therapies has come under evaluation, including bulevirtide, lonafarnib, pegylated interferon lambda, and REP-2139 creating excitement with this viral infection. However, there has been significant variability in the endpoints used to evaluate these therapeutics. One of the recently introduced endpoints is characterized by a decline in HDV RNA by 2 logs, with or without achieving an undetectable serum hepatitis D virus (HDV) RNA, as a marker of virologic response. Furthermore, this measure has been combined with alanine aminotransferase normalization, also known as a biochemical response, to formulate the primary endpoint of several late-stage studies. Per recent guidance by the US Food and Drug Administration, these should be surrogate endpoints that will ultimately portend long-term clinical benefits. These clinical benefits may include reducing the risk of progression to cirrhosis, hepatic decompensation, hepatocellular carcinoma, liver transplantation, and mortality. However, the optimal way to measure success in HDV clinical trials remains unknown and will continue to evolve., (Copyright © 2023 American Association for the Study of Liver Diseases.)

- Abstract
Background: Fibrosis impacts long-term outcomes among patients with nonalcoholic fatty liver disease (NAFLD). Due to well-documented flaws associated with liver biopsy, there has been a recent emphasis on prioritizing noninvasive testing over liver biopsy for the assessment of fibrosis., Methods: A comprehensive systematic review and frequentist random effects network meta-analysis was performed among randomized controlled trials reporting pharmacologic intervention in NAFLD. The primary endpoint was the absolute change in liver stiffness measurement (LSM) via elastography. Secondary endpoints included changes in noninvasive serologic tests including APRI, fibrosis-4 index, NAFLD fibrosis score, enhanced liver fibrosis (ELF) and FibroTest (FibroSure in the USA)., Results: Forty-five randomized controlled trials enrolling 6932 patients were identified for this network meta-analysis. Across the primary endpoint, firsocostat, semaglutide, montelukast, cilofexor plus firsocostat, obeticholic acid and diacerein (change in LSM via vibration controlled transient elastography), in addition to lubiprostone and pemafibrate (change in LSM via magnetic resonance elastography) were found to be the most effective and statistically significant treatment interventions. Similarly, the following interventions were determined to be most effective as compared to placebo among secondary endpoints: saroglitazar, lubiprostone, and obeticholic acid (change in APRI); saroglitazar, semaglutide, firsocostat and cilofexor plus firsocostat (change in ELF); obeticholic acid and belapectin [change in FibroTest/FibroSure]., Conclusion: This is the first systematic review and network meta-analysis reporting pharmacologic efficacy in the progression of fibrosis based on noninvasive testing among patients with NAFLD. Semaglutide, obeticholic acid, firsocostat, cilofexor plus firsocostat and lubiprostone were found to be the most effective treatments based on their consistent efficacy reproduced across multiple endpoints, both via elastography and noninvasive blood tests., (Copyright © 2022 Wolters Kluwer Health, Inc.

- Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver cancer whose incidence continues to rise in many parts of the world due to a concomitant rise in many associated risk factors, such as alcohol use and obesity. Although early-stage HCC can be potentially curable through liver resection, liver-directed therapies, or transplantation, patients usually present with intermediate to advanced disease, which continues to be associated with a poor prognosis. This is because HCC is a cancer with significant complexities, including substantial clinical, histopathologic, and genomic heterogeneity. However, the scientific community has made a major effort to better characterize HCC in those aspects via utilizing tissue sampling and histological classification, whole genome sequencing, and developing viable animal models. These efforts ultimately aim to develop clinically relevant biomarkers and discover molecular targets for new therapies. For example, until recently, there was only one approved systemic therapy for advanced or metastatic HCC in the form of sorafenib. Through these efforts, several additional targeted therapies have gained approval in the United States, although much progress remains to be desired. This review will focus on the link between characterizing the pathogenesis of HCC with current and future HCC management., Competing Interests: CONFLICTS OF INTEREST Authors have no conflicts of interest to declare.

- Abstract
Background: Graft macrosteatosis can predispose to a higher risk of graft loss so we sought to redefine acceptable cutoffs for graft steatosis., Methods: Data of 26,103 donors who underwent liver transplantation (LT) between January 2004 and December 2018 from the UNOS-STAR database were utilized. A high-risk steatotic (HRS) graft and a low-risk steatotic (LRS) graft were defined as ≥20% and <20% macrosteatosis, respectively. High-risk steatotic grafts were further classified as grafts with 20-29% (G1S grafts), 30-39% (G2S grafts), and ≥40% steatosis (G3S grafts). Outcomes between groups were compared., Results: LRS grafts had excellent graft (93.3 and 87.7%) and overall survival (95.4 and 90.5%) at 90 days and 1 year. Compared to LRS grafts, G1S, G2S, and G3S grafts had worse graft and overall survival at 90 days and 1-year ( p <0.001). There was no difference in graft or overall survival of G1S or G3S grafts compared to G2S grafts until after adjustment in which G3S grafts were found to be associated with an increased risk of graft loss-aHR 1.27 (1.03-1.57), p = 0.02., Discussion: Liver grafts can be categorized into three categories: (1) <20% or "very low risk", (2) 20-39% or "low-to-moderate risk", and usually acceptable, and (3) ≥40% steatosis or "moderate-to-high risk"., How to Cite This Article: Da BL, Satiya J, Heda RP, et al .

- Abstract
Hepatorenal syndrome (HRS) is a hemodynamically driven process mediated by renal dysregulation and inflammatory response. Albumin, antibiotics, and β-blockers are among therapies that have been studied in HRS prevention. There are no Food and Drug Administration-approved treatments for HRS although multiple liver societies have recommended terlipressin as first-line pharmacotherapy. Renal replacement therapy is the primary modality used to bridge to definitive therapy with orthotopic liver transplant or simultaneous liver-kidney transplant. Advances in our understanding of HRS pathophysiology and emerging therapeutic modalities are needed to change outcomes for this vulnerable population., (Copyright © 2022 Elsevier Inc.

- Abstract
In order to determine the relationship between socioeconomic deprivation and nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH), we retrospectively reviewed the electronic medical records of 1,430 patients in a large tertiary health care network in New York. These patients underwent liver biopsy over a 10-year period and were included in our study if they had evidence of NAFLD/NASH on liver biopsy. Zip codes were used to obtain data necessary to derive the social deprivation index (SDI) from the US Bureau of the Census. The high-SDI group was compared to the low-SDI group. Univariate and multivariate logistic regressions were performed to assess association between socioeconomic factors and NAFLD parameters, including presence of NASH (NAFLD activity score >4), moderate to severe steatosis (>33%), and significant fibrosis (S2-S4). We included 614 patients with NAFLD/NASH; the median SDI was 31.5. Hemoglobin A1c values were higher in the high-SDI group compared to the low-SDI group (6.46 vs. 6.12, P = 0.02). Socioeconomic factors, such as private versus public health care, percentage being foreign born, percentage without a car, percentage with higher needs (<5 years old and >65 years old), and percentage currently living in renter-occupied and crowded housing units, showed statistically significant associations in predicting NASH. After adjusting for patient age, sex, race, body mass index, and diabetes, we saw a significant association between four or more socioeconomic parameters in predicting NASH (odds ratio [OR], 1.71; 95% confidence interval [CI], 1.099-2.856; P = 0.0190) and six or more socioeconomic parameters in predicting severe steatosis (OR, 1.498; 95% CI, 1.031-2.176; P = 0.0338) but no significant correlation between the number of socioeconomic parameters and significant fibrosis. Conclusion: Greater number of socioeconomic determinants (four or more) are associated with greater severity of NASH. Awareness of NAFLD/NASH needs to be raised in communities with high socioeconomic deprivation., (© 2021 The Authors.

- Abstract
Background: Without available curative therapies for delta hepatitis (hepatitis delta virus [HDV]), hepatic decompensation and hepatocellular carcinoma (HCC) among HDV patients often necessitates liver transplantation (LT). The objective of this study was to evaluate outcomes of LT among hepatitis B virus (HBV)/HDV patients in the United States., Methods: We performed the first US-based retrospective study of patients who underwent LT for HDV compared with HBV (monoinfection) in the years 2002-2019. We evaluated posttransplant survival and predictors of survival., Results: We identified a total of 152 HBV/HDV and 5435 HBV patients who underwent LT. HDV patients were younger at transplant (52 versus 55, P < 0.001), less commonly Asian (16% versus 36%, P < 0.001), more likely to be HCV Ab positive (42% versus 28%, P < 0.001), and less likely to be listed for LT with HCC (38% versus 51%, P = 0.001), more likely to have ascites (73% versus 64%, P = 0.019), had worse coagulopathy (mean INR 2.0 versus 1.82, P = 0.04), and were more likely to receive a HCV-positive donor organ (7% versus 3%, P = 0.001). Post-LT overall survival and graft survival were similar between HDV and HBV patients, including among patients with HCC. Older age, HCV coinfection, HCC, and higher model for end-stage liver disease at transplant were associated with higher posttransplant mortality., Conclusions: HDV patients were sicker and more likely to be listed for LT for decompensated disease compared with HBV patients. Post-LT survival was similar between HDV and HBV patients, in contrast to prior international studies that suggested worse post-LT survival in HBV patients due to higher rates of HBV reactivation., Competing Interests: The authors declare no funding or conflicts of interest., (Copyright © 2021 The Author(s).

- Abstract
Background and Aims: The surge in unhealthy alcohol use during the COVID-19 pandemic may have detrimental effects on the rising burden of alcohol-associated liver disease (ALD) on liver transplantation (LT) in the USA. We evaluated the effect of the pandemic on temporal trends for LT including ALD., Approach and Results: Using data from United Network for Organ Sharing, we analyzed wait-list outcomes in the USA through March 1, 2021. In a short-period analysis, patients listed or transplanted between June 1, 2019, and February 29, 2020, were defined as the "pre-COVID" era, and after April 1, 2020, were defined as the "COVID" era. Interrupted time-series analyses using monthly count data from 2016-2020 were constructed to evaluate the rate change for listing and LT before and during the COVID-19 pandemic. Rates for listings (P = 0.19) and LT (P = 0.14) were unchanged during the pandemic despite a significant reduction in the monthly listing rates for HCV (-21.69%, P < 0.001) and NASH (-13.18%; P < 0.001). There was a significant increase in ALD listing (+7.26%; P < 0.001) and LT (10.67%; P < 0.001) during the pandemic. In the COVID era, ALD (40.1%) accounted for more listings than those due to HCV (12.4%) and NASH (23.4%) combined. The greatest increase in ALD occurred in young adults (+33%) and patients with severe alcohol-associated hepatitis (+50%). Patients with ALD presented with a higher acuity of illness, with 30.8% of listings and 44.8% of LT having a Model for End-Stage Liver Disease-Sodium score ≥30., Conclusions: Since the start of COVID-19 pandemic, ALD has become the most common indication for listing and the fastest increasing cause for LT. Collective efforts are urgently needed to stem the rising tide of ALD on health care resources., (© 2021 by the American Association for the Study of Liver Diseases.)

- Abstract
Background: Hepatitis delta virus (HDV) infection is the most aggressive form of chronic viral hepatitis. Response rates to therapy with 1- to 2-year courses of pegylated interferon alpha (peginterferon) treatment are suboptimal., Aims: To evaluate the long-term outcomes of patients with chronic hepatitis D after an extended course of peginterferon., Methods: Patients were followed after completion of trial NCT00023322 and classified based on virological response defined as loss of detectable serum HDV RNA at last follow-up. During extended follow-up, survival and liver-related events were recorded., Results: All 12 patients who received more than 6 months of peginterferon in the original study were included in this analysis. The cohort was mostly white (83%) and male (92%) and ranged in age from 18 to 58 years (mean = 42.6). Most patients had advanced but compensated liver disease at baseline, a median HBV DNA level of 536 IU per mL and median HDV RNA level of 6.86 log
10 genome equivalents per mL. The treatment duration averaged 6.1 years (range 0.8-14.3) with a total follow-up of 8.8 years (range 1.7-17.6). At last follow-up, seven (58%) patients had durable undetectable HDV RNA in serum, and four (33%) cleared HBsAg. Overall, one of seven (14%) responders died or had a liver-related event vs four of five (80%) non-responders., Conclusions: With further follow-up, an extended course of peginterferon therapy was found to result in sustained clearance of HDV RNA and favourable clinical outcomes in more than half of patients and loss of HBsAg in a third., (Published 2021.

Aims: Report the real-world experience of the efficacy and safety of sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) in chronic hepatitis C virus (HCV) infected patients who have previously experienced a direct-acting antiviral (DAA) containing regimen., Methods: Consecutive patients who have previously failed or did not tolerate a DAA containing regimen for chronic HCV who was treated with SOF/VEL/VOX were studied. Baseline clinical and laboratory data including NS5A RAS mutation testing were collected., Results: SOF/VEL/VOX resulted in an end of treatment undetectable HCV viral load in all patients and a sustained virologic response 12 rate of 100% despite the presence of NS5A RAS mutation, HIV infection, and cirrhosis. Treatment with SOF/VEL/VOX was well tolerated and there were no adverse events., Conclusions: SOF/VEL/VOX is well tolerated and effective in treating patients who have been exposed to prior DAA therapy outside of clinical trials. SOF/VEL/VOX should be considered as the first-line regimen in HCV infected patients who have experienced prior DAA failure., (Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Objective: Coronavirus disease 2019 [COVID-19] infection in patients with chronic liver disease [CLD] may precipitate acute-on-chronic liver failure [ACLF]. In a large multi-center cohort of COVID-19-infected patients, we aim to analyze (1) the outcomes of patients with underlying CLD [with and without cirrhosis] and (2) the development and impact of ACLF on in-hospital mortality., Design: We identified 192 adults with CLD from among 10,859 patients with confirmed COVID-19 infection (admitted to any of 12 hospitals in a New York health care system between March 1, 2020 and April 27, 2020). ACLF was defined using the EASL-CLIF Consortium definition. Patient follow-up was through April 30, 2020, or until the date of discharge, transfer, or death., Results: Of the 84 patients with cirrhosis, 32 [38%] developed ACLF, with respiratory failure [39%] and renal failure [26%] being the most common. Hispanic/Latino ethnicity was particularly at higher risk of in-hospital mortality [adjusted HR 4.92, 95% 1.27-19.09, p < 0.02] in cirrhosis despite having lower risk of development of ACLF [HR 0.26, 95% CI 0.08-0.89, p = 0.03]. Hypertension on admission predicted development of ACLF [HR 3.46, 95% CI 1.12-10.75, p = 0.03]. In-hospital mortality was not different between CLD patients with or without cirrhosis [p = 0.24] but was higher in those with cirrhosis who developed ACLF [adjusted HR 9.06, 95% CI 2.63-31.12, p < 0.001] with a trend for increased mortality by grade of ACLF [p = 0.002]. There was no difference in in-hospital mortality between the CLD cohort compared to matched control without CLD (log rank, p = 0.98) and between the cirrhosis cohort compared to matched control without cirrhosis (log rank, p = 0.51)., Conclusion: Development of ACLF is the main driver of increased in-hospital mortality in hospitalized patients with COVID-19 infection and cirrhosis., (© 2021.

Introduction: The American Association for the Study of Liver Diseases recommends hepatitis D virus (HDV) screening in certain high-risk groups; however, the effectiveness is unknown., Methods: A study of North American patients with hepatitis B (HBV) referred to the NIH was performed to identify risk factors associated with HDV infection. Active HDV was "confirmed" by serum HDV RNA or histologic HDV antigen staining., Results: Six hundred fifty-two were studied, of which 91 were HDV "confirmed." Independent risk factors for HDV included: intravenous drug users, HBV-DNA <2,000 IU/mL, alanine aminotransferase >40 U/L, and HDV endemic country of origin., Disussion: North American patients with HBV and significant risk factors should be screened for HDV., (Copyright © 2020 by The American College of Gastroenterology.)

- Abstract
Liver injury is commonly seen in coronavirus disease 2019 (COVID-19); however, the mechanism behind liver injury, particularly in patients with severe and critical COVID-19, remains unclear, and the clinical course is poorly described. We conducted a single-center retrospective cohort study of consecutive patients hospitalized with severe and critical COVID-19 with or without liver injury and who underwent immunologic testing (interleukin [IL]-6, IL-8, tumor necrosis factor alpha [TNF-α], and IL-1β). Liver injury was defined as peak aminotransferases ≥3 times the upper limit of normal (40 U/L) or ≥120 U/L. Patients with liver injury were compared to those who had normal aminotransferases throughout the hospital course. We studied 176 patients: 109 with liver injury and 67 controls. Patients with liver injury were more likely to be men (71.6% vs. 37.3%, P < 0.001). Peak inflammatory markers and IL-6 were higher in the liver injury group: C-reactive protein (CRP), 247 vs. 168 mg/L, P < 0.001; lactate dehydrogenase (LDH), 706 vs. 421 U/L; ferritin, 2,973 vs. 751 ng/mL, P < 0.001; IL-6, 121.0 vs. 71.8 pg/mL, P < 0.001. There was no difference in the levels of IL-8, TNF-α, and IL-1β. The liver injury group had a longer length of stay in the hospital and more severe COVID-19 despite having less diabetes and chronic kidney disease. Conclusion: An exaggerated hyperinflammatory response (cytokine storm) characterized by significantly elevated CRP, LDH, ferritin, and IL-6 levels and increasing severity of COVID-19 appears to be associated with the occurrence of liver injury in patients with severe/critical COVID-19., (© 2020 The Authors.

- Abstract
Importance: Increased utilization of hepatitis C virus (HCV)-positive liver allografts for liver transplant (LT) has been endorsed as one of several ways to combat national organ shortages. However, HCV-positive donors remain poorly characterized, and Organ Procurement and Transplantation Network regional differences in the utilization of HCV-positive liver allografts are unclear., Objective: To characterize HCV-positive donors and the allografts that come from them., Design, Setting, and Participants: In this cross-sectional study, the Scientific Registry of Transplant Recipients database was queried for all donors who underwent HCV testing from June 2015 to December 2018. Clinical and allograft characteristics were evaluated, and utilization across the United States was studied. Patients with positive or negative results for HCV antibody (Ab) and HCV nucleic acid amplification testing (NAT) were included in this study. Donors utilized for living donor transplant and pediatric (age <18 years) recipients were excluded., Main Outcomes and Measures: The primary comparison was between donors who were HCV Ab positive and those who were HCV Ab negative. Regional variations in the utilization of HCV-positive and HCV-negative donors were analyzed., Results: Of 24 500 donors utilized for LT, 1887 (7.7%) were HCV Ab positive; 64.4% of HCV Ab-positive donors were HCV NAT positive. HCV Ab-positive donors were younger (median [interquartile range] age, 35 [29-46] years vs 40 [27-54] years) and had fewer comorbidities, such as diabetes (8.3% vs 12.0%) and hypertension (25.9% vs 35.2%), compared with HCV Ab-negative donors. These findings were even more pronounced in HCV Ab-positive /NAT-positive compared with HCV Ab-positive/NAT-negative donors. Organ Procurement and Transplantation Network regions 2, 3, 10, and 11 had the highest absolute utilization of HCV Ab-positive donors, accounting for 64.4% of all HCV Ab-positive donors used in the United States. Region 1 had the highest relative utilization of HCV Ab-positive donors (18.7%). The use of HCV Ab-positive donors in some regions was associated with the rate of drug overdose, but this was not always the case. Similar utilization results were found with HCV NAT-positive donors., Conclusions and Relevance: In this cross-sectional study, HCV-positive donors were younger and healthier than utilized HCV-negative donors. Significant differences exist in the utilization of HCV-positive donors across the 11 Organ Procurement and Transplantation Network regions, which is not entirely explained by organ demand or by higher availability of HCV-positive livers as per the distribution of the opioid epidemic. Initiatives to increase the use of HCV-positive donors, particularly in regions of high organ demand, should be implemented.

- Abstract
COVID-19 is a global pandemic that started in Wuhan, China. COVID-19 related liver enzyme elevations have been described however the clinical presentation, enzyme kinetics, and associated laboratory abnormalities of these patients have not been well described. Five cases of COVID-19 associated liver enzyme elevations are reported here. We found that COVID-19 related liver enzyme elevations occurred in a hepatocellular pattern and persisted throughout the initial hospitalization in all patients. Abnormalities in lactate dehydrogenase and ferritin levels were seen in all five cases. In conclusion, abnormalities in aminotransferase, lactate dehydrogenase, and ferritin levels are commonly seen in COVID-19 related liver injury. Elevated aminotransferase levels often persist throughout the entire hospitalization. However, the clinical course of COVID-19 related liver injury appears benign.

- Abstract
The coronavirus disease 2019 (COVID-19) pandemic has had a tremendous global impact since it began in November of 2019. However, there are concerns that the COVID-19 pandemic will not affect all equally and that some populations will be particularly vulnerable. Relevant to liver disease, patients with alcohol use disorder (AUD) and alcohol-associated liver disease (ALD) may be among the populations that are the most severely impacted. The reasons for this include being at a higher risk of severe COVID-19 infection due to a depressed immune system and high-risk underlying comorbidities, the injurious effect of COVID-19 on the liver, the inability to attend regular visits with providers, diversion of hospital resources, and social isolation leading to psychological decompensation and increased drinking or relapse. As a result, we fear that there will be a dramatic rising tide of alcohol relapse, admissions for decompensated ALD, and an increase in newly diagnosed patients with AUD/ALD post-COVID-19 pandemic. Providers and their institutions should implement preemptive strategies such as telehealth and aggressive patient outreach programs now to curb this anticipated problem. Liver transplantation (LT) centers should adapt to the pandemic by considering leniency to some LT candidates with ALD who cannot access appropriate alcohol treatment due to the current situation. In conclusion, the COVID-19 pandemic will likely be especially detrimental to patients with AUD/ALD, and actions need to be taken now to limit the scope of this anticipated problem., (© 2020 by the American Association for the Study of Liver Diseases.)

- Abstract
Noninvasive detection of cirrhosis via vibration-controlled transient elastography (VCTE) has revolutionized the management of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. However, VCTE has not been studied in chronic hepatitis D virus (HDV) infection and accuracy remains in question due to the significant hepatic inflammation associated with this infection. Consecutive HBV, HCV and HDV patients who underwent VCTE (2006-2019) were evaluated. Diagnosis of cirrhosis was made via liver biopsy or clinical findings. VCTE was compared with other noninvasive serum fibrosis tests using AUROC curves. The performance of VCTE in HBV/HCV/HDV was also compared. We evaluated 319 patients (HBV-112; HCV-132; HDV-75), 278(87%) patients had histology for evaluation. HDV patients had evidence of higher hepatic inflammation as evidence by aspartate aminotransferase, alanine aminotransferase and histology activity index. Cirrhotic HDV patients had higher mean liver stiffness measurements compared with noncirrhotic patients (29.0 vs 8.3 kPa, P < .0001). VCTE demonstrated excellent diagnostic accuracy for the detection of cirrhosis with an AUROC of 0.90 compared with APRI (0.83), FIB-4 (0.88), AAR (0.73) and RPR (0.85). Performance of VCTE in HDV was comparable with HBV (0.93) and HCV (0.94). At the optimized cut-off value of ≥14.0 kPa for determining cirrhosis in HDV, VCTE had a sensitivity of 0.78, specificity of 0.86, NPV of 0.93 and PPV of 0.64. Hence, VCTE is a useful noninvasive test in HDV for determining cirrhosis despite the presence of significant hepatic inflammation., (Published [2019].

- Abstract
Background: Chronic Hepatitis D virus (HDV) infection results in the most severe form of viral hepatitis with a rapid progression to cirrhosis. However, non-invasive fibrosis tests that can accurately predict cirrhosis have not been adequately validated. We aimed to develop a clinically useful non-invasive score that can accurately detect cirrhosis., Material and Methods: Patients with chronic HDV diagnosed by liver histology or serum PCR were evaluated. Data regarding demographics, laboratory, imaging, vibration-controlled transient elastography (VCTE), and liver biopsy were collected. The total cohort was randomized into a training and validation cohort. The training cohort was used to develop a novel score, the Delta-4 fibrosis score (D4FS) which was then compared to other non-invasive tests in the validation cohort by area under receiver operating characteristics (AUROC)., Results: 77 patients with chronic HDV were evaluated: mean age 42.6 (SD:11.1) years, 59.7% male, and 57.1% Asian. The total cohort was then separated into a training (n = 45) and validation (n = 32) cohort with no significant differences in terms of clinical characteristics between the two. From the training cohort, the D4FS was derived from variables of statistical and clinical interest (gamma-glutamyl transpeptidase (GGT), platelet count, alanine aminotransferase (ALT), and liver stiffness measurement (LSM)). The D4FS demonstrated the best AUROC in the validation cohort (0.94) followed by VCTE (0.90), FIB-4 (0.86), APRI (0.81), and AAR (0.71)., Discussion: The D4FS is a clinically useful non-invasive fibrosis score that can accurately detect cirrhosis in patients with chronic HDV infection. Further studies should be performed to further validate clinical utility., Competing Interests: Declaration of competing interest The authors have no relevant conflicts of interest., (Published by Elsevier B.V.)

Chronic hepatitis D (CHD) results from an infection with the hepatitis B virus and hepatitis D virus (HDV). CHD is the most severe form of human viral hepatitis. Current treatment options consist of interferon alfa, which is effective only in a minority of patients. Study of HDV molecular virology has resulted in new approaches entering clinical trials, with phase-3 studies the most advanced. These include the entry inhibitor bulevirtide, the nucleic acid polymer REP 2139-Ca, the farnesyltransferase inhibitor lonafarnib, and pegylated interferon lambda. This article summarizes the available data on these emerging therapeutics., (Published by Elsevier Inc.)

- Abstract
With the success of hepatitis C virus (HCV) direct-acting antiviral therapies, there has been a shift in research focus to the other major chronic liver diseases (CLDs). The use of social media, specifically Twitter, has become a popular platform for understanding public health trends and for performing health care research. To evaluate this, we studied the areas of public interest and social media trends of the following three major CLDs: hepatitis B virus (HBV), HCV, and nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH). Twitter activity data from January 1, 2013, through January 1, 2019, for HBV, HCV, and NAFLD/NASH were collected using the social media analytic tool Symplur Signals (Symplur LLC) software. Content and regression analyses were performed to understand and predict Twitter activity for each of the CLDs. Over the study period, there were 810,980 tweets generating 4,452,939,516 impressions. HCV tweet activity peaked in 2015 at 243,261 tweets, followed by a decline of 52.4% from 2015 to 2016 with a subsequent plateau through 2018. Meanwhile, NAFLD/NASH and HBV tweet activity has continued to increase, with projections that these two CLDs will surpass HCV by the second half of 2023 and 2024, respectively. Treatment and Management was the most popular content category for HCV and NAFLD/NASH, while Prevention was the most popular content category for HBV. Conclusion: Twitter is a useful social media tool to gauge public interest in liver disease over time. The information provided by Twitter can be used to identify gaps in public knowledge or highlight areas of interest that may need further research. Future studies on the use of Twitter in liver disease are warranted.

33. Hepatitis D infection: from initial discovery to current investigational therapies.

Da BL, Heller T, and Koh C
- Abstract
Hepatitis D is the most severe form of viral hepatitis associated with a more rapid progression to cirrhosis and an increased risk of hepatocellular carcinoma and mortality compared with hepatitis B mono-infection. Although once thought of as a disappearing disease, hepatitis D is now becoming recognized as a serious worldwide issue due to improvement in diagnostic testing and immigration from endemic countries. Despite these concerns, there is currently only one accepted medical therapy (pegylated-interferon-α) for the treatment of hepatitis D with less than desirable efficacy and significant side effects. Due to these reasons, many patients never undergo treatment. However, increasing knowledge about the virus and its life cycle has led to the clinical development of multiple promising new therapies that hope to alter the natural history of this disease and improve patient outcome. In this article, we will review the literature from discovery to the current investigational therapies., (Published by Oxford University Press and Sixth Affiliated Hospital of Sun Yat-sen University.)

- Abstract
Granulocyte-colony-stimulating factors such as filgrastim are currently used for multiple indications, one of which is administration to healthy donors for allogeneic stem cell collection. So far, filgrastim has not been described as a cause of drug-induced liver injury. We report a case of drug-induced liver injury secondary to filgrastim use in a 54-year-old healthy donor. The patient presented with an upsurge of liver enzymes a week from the drug administration with a rapid downtrend over the next few weeks. We wish to highlight the possibility of a similar idiosyncratic adverse drug reaction in other healthy individuals., (© 2019 The Author(s).

- Abstract
Purpose of Review: Noncirrhotic portal hypertension represents a heterogeneous group of liver disorders that is characterized by portal hypertension in the absence of cirrhosis. The purpose of this review is to serve as a guide on how to approach a patient with noncirrhotic portal hypertension with a focus on recent developments., Recent Findings: Recent studies pertaining to noncirrhotic portal hypertension have investigated aetiological causes, mechanisms of disease, noninvasive diagnostic modalities, clinical characteristics in the paediatric population and novel treatment targets., Summary: Noncirrhotic portal hypertension is an underappreciated clinical entity that can be difficult to diagnosis without a healthy suspicion. Diagnosis then relies on a comprehensive understanding of the causes and clinical manifestations of this disease, as well as a careful interpretation of the liver biopsy. Noninvasive approaches to diagnosis may play a significant role moving forward in this disease. Treatment in NCPH remains largely targeted at the individual sequalae of portal hypertension.

- Abstract
Objective: The diagnosis of acute pancreatitis (AP) is defined as a constellation of abnormal pancreatic enzymes, imaging, and characteristic pain. The origin and clinical significance of isolated hyperlipasemia is unclear., Methods: We prospectively evaluated patients with serum lipase level greater than 3 times the upper limit of normal (ULN) admitted to Los Angeles County Hospital from October 2014 to April 2015. Patients were identified by a daily laboratory query used to support an ongoing randomized trial of goal-directed therapy for AP (NCT 01761539). Nonpancreatic hyperlipasemia (NPHL) was defined as a serum lipase level greater than 3 times the ULN without characteristic pain or imaging., Results: Among 221 patients with lipase level greater than 3 times the ULN, 170 met criterion for AP, and 51 did not. The leading etiologies for NPHL were decompensated cirrhosis and renal failure. Patients with NPHL were significantly older and had more comorbidities and lower serum lipase levels (360 ± 36 vs 1453 ± 135 IU/L, P < 0.001). There were no differences in length of hospitalization, intensive care unit admission, or mortality., Conclusions: Elevated serum lipase level has many nonpancreatic origins, with liver and renal failure being the most frequent. Distinct clinical features can help to differentiate between AP and NPHL.

- Abstract
Objective: The aim of this study was to assess the degree of perception of occlusal plane inclination and mandibular deviation in facial esthetics, assessed by laypeople, dentists and orthodontists., Methods: A woman with 5.88° of inclination and 5.54 mm of mandibular deviation was selected and, based on her original photograph, four new images were created correcting the deviations and creating more symmetric faces and smiles. Examiners assessed the images by means of a questionnaire. Their opinions were compared by qualitative and quantitative analyses., Results: A total of 45 laypeople, 27 dentists and 31 orthodontists filled out the questionnaires. All groups were able to perceive the asymmetry; however, orthodontists were more sensitive, identifying asymmetries as from 4.32° of occlusal plane inclination and 4.155 mm of mandibular deviation (p< 0.05). The other categories of evaluators identified asymmetries and assigned significantly lower grades, starting from 5.88° of occlusal plane inclination and 5.54 mm of mandibular deviation (p< 0.05)., Conclusion: Occlusal plane inclination and mandibular deviation were perceived by all groups, but orthodontists presented higher perception of deviations.

- Abstract
Objective: The aim of this study was to assess the regional influence on the perception of facial profile esthetics in Rio de Janeiro state (RJ) and Rio Grande do Sul state (RS), Brazil., Methods: Two Caucasian models, a man and a woman, with balanced facial profiles, had their photographs digitally manipulated so as to produce seven different profiles. First year dental students (laypeople) assessed the images and classified them according to their esthetic preference., Results: The result of the t test for independent samples showed differences among states for certain facial profiles. The female photograph identified with the letter 'G' (mandibular retrusion) received higher scores in RS state (p = 0.006). No differences were found for male photographs (p > 0.007). The evaluators' sex seemed not to influence their esthetic perception (p > 0.007). Considering all evaluators together, ANOVA/Tukey's test showed differences among the profiles (p ≤ 0.05) for both male and female photographs. The female photograph that received the highest score was the one identified with the letter 'F' (dentoalveolar bimaxillary retrusion/ straight profile). For the male profiles, photograph identified with the letter 'E' (dentoalveolar bimaxillary protrusion/ straight profile) received the best score., Conclusion: Regional differences were observed regarding preferences of facial profile esthetics. In Rio de Janeiro state, more prominent lips were preferred while in Rio Grande do Sul state, profiles with straight lips were favored. Class III profiles were considered less attractive.

- Abstract
Objectives: To describe the capability of soccer players to stabilize pelvic position actively in the transverse plane; and, to evaluate the influence of lower limb dominance, length of exposure to soccer practice, and field position on pelvic stabilization capability., Design: Cross-sectional., Participants: Sixty-eight soccer players from under-15 (U-15) and professional categories., Main Outcome Measures: Magnitude and asymmetry of pelvic tilt in the transverse plane, evaluated using the bridge test with unilateral knee extension., Results: The magnitude of pelvic tilt did not differ between dominant and non-dominant sides, suggesting absence of relative asymmetry. However, there was difference between the sides of greater and lesser magnitude of pelvic tilt, indicating presence of absolute asymmetry. Players with shorter length of exposure to soccer practice (U-15 group) had greater pelvic tilt than players with longer length of exposure (professional group). There was no association of field position with the magnitude and asymmetry of pelvic tilt., Conclusion: Soccer players showed asymmetry in pelvic stabilization capability that was unrelated to lower limb dominance or field position. Athletes with longer length of exposure to soccer practice present better capability to stabilize the pelvis in the transverse plane than those with shorter length of exposure to soccer practice., (Copyright © 2013 Elsevier Ltd.

- Abstract
EGCG, a major component of green tea, has a number of properties which includes it being a powerful antioxidant. The purpose of this investigation was to deduce whether inclusion of EGCG in the drinking water of albino rats attenuates the effect of a light insult (2200lx, for 24h) to the retina. TUNEL-positive cells were detected in the outer nuclear layer of the retina, indicating the efficacy of the light insult in inducing photoreceptor degeneration. Moreover, Ret-P1 and the mRNA for rhodopsin located at photoreceptors were also significantly reduced as well as the amplitude of both the a- and b-waves of the electroretinogram was also reduced showing that photoreceptors in particular are affected by light. An increase in protein/mRNA of GFAP located primarily to Müller cells caused by light shows that other retinal components are also influenced by the light insult. However, antigens associated with bipolar (alpha-PKC), ganglion (Thy-1) and amacrine (GABA) cells, in contrast, appeared unaffected. The light insult also caused a change in the content of various proteins (caspase-3, caspase-8, PARP, Bad, and Bcl-2) involved in apoptosis. A number of the changes to the retina caused by a light insult were significantly attenuated when EGCG was in the drinking water. The reduction of the a- and b-waves and photoreceptor specific mRNAs/protein caused by light were significantly less. In addition, EGCG attenuated the changes caused by light to certain apoptotic proteins (especially at after 2 days) but did not appear to significantly influence the light-induced up-regulation of GFAP protein/mRNA. It is concluded that orally administered EGCG blunts the detrimental effect of light to the retina of albino rats where the photoreceptors are primarily affected.
