Abstract
BACKGROUND A barrier to hepatitis C virus (HCV) cure is conventional testing. The aim of this study was to evaluate the effect of HCV antibody and RNA point-of-care-testing (POCT) on testing rates, linkage to care, treatment and acceptability of testing in three priority settings in Australia. METHODS Participants were enrolled in an interventional cohort study at a reception prison, inpatient mental health service (MHS), and inpatient alcohol and other drug (AOD) unit-between October 2020 and December 2021. HCV POCT was performed using SD Bioline HCV antibody fingerstick test and a reflexive Xpert® HCV Viral Load Fingerstick test using capillary blood samples. A retrospective audit of HCV testing and treatment data was performed at each site for the preceding 12-month period to generate a historical control. RESULTS 1,549 participants received a HCV antibody test with 17% (264/1,549) receiving a positive result, of which 21% (55/264) tested HCV RNA positive. Across all settings the rate of testing per year significantly increased between the historical controls and the study intervention period by three-fold (RR:2.57 95% CI: 2.32, 2.85) for HCV antibody testing and four-fold (RR:1.62; 95% CI:1.31, 2.01) for RNA testing. Treatment uptake was higher during the POCT intervention (86%, 47/55; P=0.010) compared to the historical controls (61%, 27/44). CONCLUSIONS This study demonstrated across three settings that the use of HCV antibody and RNA POCT increased testing rates, treatment uptake linkage to care. The testing model was highly acceptable for most participants. CLINICAL TRIAL REGISTRATION ACTRN-12621001578897.

Abstract
AIMS Standard curative options for early-stage, solitary hepatocellular carcinoma (HCC) are often unsuitable due to liver dysfunction, comorbidities and/or tumour location. Stereotactic body radiation therapy (SBRT) has shown high rates of local control in HCC; however, limited data exist in the treatment-naïve, curative-intent setting. We report the outcomes of patients with solitary early-stage HCC treated with SBRT as first-line curative-intent therapy. MATERIALS AND METHODS A multi-institutional retrospective study of treatment-naïve patients with Barcelona Clinic Liver Cancer stage 0/A, solitary ≤5 cm HCC, Child-Pugh score (CPS) A liver function who underwent SBRT between 2010 and 2019 as definitive therapy. The primary end point was freedom from local progression. Secondary end points were progression-free survival, overall survival, rate of treatment-related clinical toxicities and change in CPS >1. RESULTS In total, 68 patients were evaluated, with a median follow-up of 20 months (range 3-58). The median age was 68 years (range 50-86); 54 (79%) were men, 62 (91%) had cirrhosis and 50 (74%) were Eastern Cooperative Oncology Group 0. The median HCC diameter was 2.5 cm (range 1.3-5) and the median prescription biologically effective dose with a tumour a/b ratio of 10 Gy (BED10) was 93 Gy (interquartile range 72-100 Gy). Two-year freedom from local progression, progression-free survival and overall survival were 94.3% (95% confidence interval 86.6-100%), 59.5% (95% confidence interval 46.3-76.4%) and 88% (95% confidence interval 79.2-97.6%), respectively. Nine patients (13.2%) experienced grade ≥2 treatment-related clinical toxicities. A rise >1 in CPS was observed in six cirrhotic patients (9.6%). CONCLUSION SBRT is an effective and well-tolerated option to consider in patients with solitary, early-stage HCC. Prospective, randomised comparative studies are warranted to further refine its role as a first-line curative-intent therapy.

Abstract
BACKGROUND AND AIMS Homozygous familial hypercholesterolaemia (FH) causes severe cardiovascular disease from childhood. Conventional drug therapy is usually ineffective; lipoprotein apheresis (LA) is often required. Liver transplantation (LT) can correct the metabolic defect but is considered a treatment of last resort. Newer drugs including lomitapide and evinacumab might reduce the need for apheresis and LT. We sought to determine the long-term outcomes following LT in Australia and New Zealand. METHODS We analysed demographic, biochemical and clinical data from all patients in Australia and New Zealand who have received LT for homozygous FH, identified from the Australia and New Zealand Liver and Intestinal Transplant Registry. RESULTS Nine patients (five female; one deceased; seven aged between 3 and 6 years at the time of LT and two aged 22 and 26 years) were identified. Mean follow-up was 14.1 years (range 4-27). Baseline LDL-cholesterol off all treatment was 23 ± 4.1 mmol/L. Mean LDL-cholesterol on medical therapy (including maximal statin therapy in all patients, ezetimibe in three and LA in five) was 11 ± 5.7 mmol/L (p < 0.001). After LT, mean LDL-cholesterol was 2.6 ± 0.9 mmol/L (p = 0.004) with three patients remaining on statin therapy and none on LA. One patient died from acute myocardial infarction (AMI) three years after LT. Two patients required aortic valve replacement, more than 10 years after LT. The remaining six patients were asymptomatic after eight to 21 years of follow-up. No significant adverse events associated with immunosuppression were reported. CONCLUSIONS LT for homozygous FH was highly effective in achieving substantial long-term reduction in LDL-cholesterol concentrations in all nine patients. LT remains an option for severe cases of homozygous FH where drug therapy combined with apheresis is ineffective or unfeasible.

Abstract
Background and Aim Acute on chronic liver failure (ACLF) is a clinical syndrome described in patients with acute decompensation (AD) of cirrhosis, characterized by organ failures and high mortality. Intensive management, including liver transplantation (LT), has been shown to improve survival. To address the limited Australian data on ACLF, we describe the prevalence, clinical profile, and outcome of ACLF in an Australian cohort of hospitalized patients. Methods A retrospective review of hepatology admissions in a tertiary hospital from 1 January 2017 to 31 December 2019 identified AD and ACLF cohorts, as defined by the European Association for Study of the Liver definition. Patient characteristics, clinical course, survival at 28- and 90-day survival, and feasibility of LT were analyzed. Results Among the 192 admissions with AD, 74 admissions (39%) met ACLF criteria. A prior diagnosis of alcohol-related cirrhosis was highly prevalent in both cohorts. Grade-1 ACLF was the most frequent (60%), with renal failure being the commonest organ failure; 28-day (23% vs 2%, P = <0.001) and 90-day mortality (36% vs 16%, P = 0.002) were higher in ACLF than AD. Due to ongoing alcohol use disorder (AUD), only six patients underwent LT assessment during ACLF admission. Conclusion ACLF was common in our cohort of cirrhosis with AD and was associated with high mortality. AUD despite prior cirrhosis diagnosis was a barrier to LT. Prioritization of ACLF patients for LT after addressing AUD and relaxation of the 6-month abstinence rule may improve ACLF survival and should be addressed in prospective studies.

Abstract
BACKGROUND The epidemiology of chronic liver disease is changing with the introduction of potent antiviral therapies for chronic hepatitis C virus (HCV) and the increasing prevalence of non-alcoholic steatohepatitis (NASH). AIM To establish the impact of this change on the rates and clinical patterns of hepatocellular carcinoma (HCC) in South Australia (SA). METHODS Newly diagnosed HCC patients from January 2014 until December 2019 from four tertiary centres in SA were included. The overall age-standardised incidence rates (ASIR) of HCC were calculated using 2016 SA population as the standard. To assess the trends, Join-Point regression models were used to calculate the average annual percentage change (AAPC). Forecasting of overall and aetiology-specific HCC from 2020 to 2024 was performed using linear regression. RESULTS There were 626 new cases of HCC in SA (males 80%; median age 64 years) during the study period. There was a significant increase in NASH-related HCC (AAPC: +7.0%; P < 0.05) from 2014 to 2019. However, there were no significant differences in the ASIR for overall HCC (AAPC: -4.1%), HCV-related HCC (AAPC: -8.0%) and stage of HCC diagnosis (AAPC: +3.0%; P > 0.05). Forecasting analysis projected the decline and increase in the incidence of HCV and NASH-related HCC, respectively, over the next few years. CONCLUSION Overall ASIR of HCC has plateaued in SA. However, NASH-related HCC has increased significantly and is expected to continue to increase in the near future. Further research and intervention is required to reduce NASH-related HCC, a major contributor to the current and future burden of HCC.

Abstract
Although there are several established international guidelines on the management of hepatocellular carcinoma (HCC), there is limited information detailing specific indicators of good quality care. The aim of this study was to develop a core set of quality indicators (QIs) to underpin the management of HCC. We undertook a modified, two-round, Delphi consensus study comprising a working group and experts involved in the management of HCC as well as consumer representatives. QIs were derived from an extensive review of the literature. The role of the participants was to identify the most important and measurable QIs for inclusion in an HCC clinical quality registry. From an initial 94 QIs, 40 were proposed to the participants. Of these, 23 QIs ultimately met the inclusion criteria and were included in the final set. This included (a) nine related to the initial diagnosis and staging, including timing to diagnosis, required baseline clinical and laboratory assessments, prior surveillance for HCC, diagnostic imaging and pathology, tumor staging, and multidisciplinary care; (b) thirteen related to treatment and management, including role of antiviral therapy, timing to treatment, localized ablation and locoregional therapy, surgery, transplantation, systemic therapy, method of response assessment, and supportive care; and (c) one outcome assessment related to surgical mortality. Conclusion: We identified a core set of nationally agreed measurable QIs for the diagnosis, staging, and management of HCC. The adherence to these best practice QIs may lead to system-level improvement in quality of care and, ultimately, improvement in patient outcomes, including survival.

Abstract
BACKGROUND Chronic hepatitis B (CHB) infection remains a significant public health issue for Indigenous Australians, in particular for remote communities. AIM To evaluate the spectrum of hepatitis B virus (HBV) care provided to a remote Aboriginal community. Measures studied included screening, seroprevalence, vaccination rates and efficacy, and HCC risk and surveillance adherence. METHODS A retrospective audit of HBV care received by all permanent residents currently attending a remote Aboriginal Health service. This study was endorsed by both the local Aboriginal Health service and the Aboriginal Health Council of South Australia. RESULTS A total of 208 patients attended the clinic, of whom 52% (109) were screened for HBV. Of these, 12% (13) had CHB and 20% (22) had evidence of past infection. Similarly, of the 208 attending patients, complete vaccination was documented in 48% (99). Of the 33 patients with post-vaccination serology, 24% (8) had subtherapeutic (<10 IU/mL) levels of HBsAb. Subtherapeutic HBsAb was independently associated with higher Charlson Comorbidity scores (odds ratio = 17.1; 95% confidence interval 1.2-243.3; P = 0.036). Definitive breakthrough infection was identified in 6% (2) patients. One HBsAg positive patient was identified as needing HCC surveillance, but had not undertaken HCC surveillance. CONCLUSION Opportunities to improve the quality of CHB care through increased HBV vaccination, screening and adherence to HCC surveillance were identified. High rates of subtherapeutic vaccine responses and documented breakthrough infection raises concerns about the effectiveness of current CHB vaccines in this population.

Abstract
The prognostic role of cardiac dysfunction in cirrhotic patients is increasingly recognised. We studied its impact on morbidity and mortality before and after liver transplantation (LT) including development of post-transplant cardiovascular disease (CVD). In this retrospective study, cirrhotic patients who underwent LT assessment from January 2010 to December 2020 were reviewed. Demographics, cardiac investigations and clinical course were analysed to identify prevalence of cardiac dysfunction and its role in LT outcomes. Survival analysis was performed using Cox proportional hazard regression modelling, with LT as a time-varying covariate and as an interaction variable with cardiac dysfunction. 308 patients (70% male) were studied. The median (interquartile range) age at LT assessment was 56 (12) years. Cardiac dysfunction was found in 178 (58%) patients (diastolic, 169; systolic, 26; both, 17) and was significantly associated with hepatorenal syndrome/acute kidney injury and peri- and post-transplant morbidity (adjusted odds ratio [aOR] 1.94, 95%CI 1.06-3.52, p < 0.001; aOR 2.01, 95%CI 1.06-3.82, p = 0.033; aOR 1.9, 95%CI 1.01-3.65, p = 0.023, respectively). Cardiac dysfunction was not associated with mortality before (adjusted hazard ratio [aHR] 1.01, 95% CI 0.99-1.01) or after LT (aHR 0.74, 95% CI 0.4-1.05. Post-transplant CVD (61% cardiac failure) occurred in 36 patients and there was no significant association with cardiac dysfunction (p = 0.11). Cardiac dysfunction was common in LT candidates and was significantly associated with morbidity before and after LT. Studies on the role of advanced echocardiographic parameters to improve diagnosis of cardiac dysfunction and optimise LT outcomes are needed. This article is protected by copyright.

Abstract
Introduction of universal access to direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) in Australia and New Zealand on March 1st , 2016, has had a major impact on the number of people with chronic HCV infection, but the impact on liver transplantation rates is unknown. We conducted a retrospective registry study including all adult liver transplantations from the Australia and New Zealand Liver and Intestinal Liver Transplant Registry (ANZLITR) data set. Interrupted time series analysis determined the impact of DAAs in 2016 on the number of HCV liver transplantations per year. Cox regression analysis was used to determine the impact of DAAs on post-liver transplantation survival. Between January 1, 1990, and December 31, 2019 5318 adult liver transplantations were performed, and 29% (1531) were for HCV infection. Prior to the introduction of DAAs, there was a mean increase of 3.5 adult liver transplantations performed for HCV per annum, but between 2016 and 2019 there was a mean decrease of 7.9 adult liver transplantations per annum (P < 0.001). Similarly, the proportion of liver transplantations performed for HCV increased from 9% (1990) to 33% in 2016 and then fell to 23% in 2019 (P < 0.001). The number and proportion of patients with HCV added to the liver transplantation waiting list also fell in 2016 (P < 0.001) when compared with other indications. The introduction of DAAs was associated with a 31% reduction in death after liver transplantation, adjusted for age at transplant and hepatocellular carcinoma (HCC; hazard ratio [HR], 0.69; 95% confidence interval [CI], 0.48-0.99; P = 0.047). The number of adult liver transplantations performed for HCV-related liver cirrhosis and HCC has reduced since the introduction of universal access to DAAs in 2016 in Australia and New Zealand.

Abstract
A nurse-led cirrhosis clinic model for management of stable, compensated cirrhotic patients is practised in our unit since 2013, wherein these patients are reviewed every six months by specialist nurses in community clinics under remote supervision of hepatologists. We evaluated the experiences of patients and healthcare providers involved in the model to understand the acceptability, strengths, and limitations of the model and obtain suggestions to improve. A qualitative design using in-depth interviews was employed, followed by thematic analysis of eight patients, one attending physician both nurse and hospital clinics, four hepatologists, and three experienced specialist nurses running the nurse-led cirrhosis clinic. Patients expressed satisfaction and a good understanding of the nurse-led cirrhosis clinic, preferring it to hospital clinics for better accessibility and the unique nurse-patient relationship. Upskilling and provision of professional care in a holistic manner were appreciated by specialist nurses. The hepatologists expressed confidence and satisfaction, although they acknowledged the difference between the medical training of specialist nurses and hepatologists. The greater availability of hospital clinic time for sick patients was welcomed. Increased specialist nurse staffing, regular forums to promote specialist nurse learning, and formalization of the referral process were suggested. No adverse experiences were reported by patients or staff. The nurse-led cirrhosis clinic model for compensated liver cirrhosis was well received by patients, hepatologists, and specialist nurses. Wider implementation of the model could be considered after further investigations in other settings.

Abstract
AIMS There has been significant evolution in operative and post-transplant therapies following liver transplantation (LT). We sought to study their impact on cardiovascular (CV) mortality, particularly in the longer term. METHODS AND RESULTS A retrospective cohort study was conducted of all adult LTs in Australia and New Zealand across three 11-year eras from 1985 to assess prevalence, modes, and predictors of early (≤30 days) and late (>30 days) CV mortality. A total of 4265 patients were followed-up for 37 409 person-years. Overall, 1328 patients died, and CV mortality accounted for 228 (17.2%) deaths. Both early and late CV mortality fell significantly across the eras (P < 0.001). However, CV aetiologies were consistently the leading cause of early mortality and accounted for ∼40% of early deaths in the contemporary era. Cardiovascular deaths occurred significantly later than non-cardiac aetiologies (8.8 vs. 5.2 years, P < 0.001). On multivariable Cox regression, coronary artery disease [hazard ratio (HR) 4.6, 95% confidence interval (CI) 1.2-21.6; P = 0.04] and era of transplantation (HR 0.44; 95% CI 0.28-0.70; P = 0.01) were predictors of early CV mortality, while advancing age (HR 1.05, 95% CI 1.02-1.10; P = 0.005) was an independent predictors of late CV mortality. Most common modes of CV death were cardiac arrest, cerebrovascular events, and myocardial infarction. CONCLUSION Despite reductions in CV mortality post-LT over 30 years, they still account for a substantial proportion of early and late deaths. The late occurrence of CV deaths highlights the importance of longitudinal follow-up to study the efficacy of targeted risk-reduction strategies in this unique patient population.

Abstract
INTRODUCTION Stereotactic body radiotherapy (SBRT) is an emerging, therapeutic option in the management of hepatocellular carcinoma (HCC). A multicentre Liver Ablative Stereotactic Radiation (LASR) database was established to provide a collaborative platform for Australian institutions to define the practice of liver SBRT for HCC. This study explores the patterns of SBRT practice amongst Australian institutions. METHODS This was a multi-institutional retrospective study of patients treated with SBRT for HCC at 10 institutions between January 2013 and December 2019. Patients' demographics, disease characteristics and SBRT details were evaluated. RESULTS Three hundred and seventeen patients were evaluated with a median age of 67 years (range, 32-90). Liver cirrhosis was present in 88.6%, baseline Child-Pugh score was A5/6 in 85.1% and B7/8 in 13.2%. Median size of HCC treated was 30 mm (range, 10-280). 63.1% had early-stage disease (Barcelona clinic liver cancer (BCLC) stage 0/A) and 36% had intermediate/advanced-stage disease (BCLC B/C). In 2013/2014, six courses of SBRT were delivered, increasing to 108 in 2019. SBRT was prescribed in five fractions for 71.3% of the cohort. The most common dose fractionation schedule was 40 Gy in five fractions (24.3%). Median biologically effective dose (BED10 ) delivered was 85.5 Gy for early-stage and 60 Gy for intermediate/advanced disease, respectively. The most common prescription range was 100-120 Gy BED10 (32.8%). CONCLUSION SBRT utilisation for HCC is increasing in Australia. There was wide variation in size of tumours and disease stages treated, and prescription patterns. Uniform reporting of clinical and dosimetric details are important in refining the role of liver SBRT.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common malignancy worldwide and the third most common cause of cancer-related death. Long-term prognosis remains poor with treatment options frequently limited by advanced tumor stage, tumor location, or underlying liver dysfunction. Stereotactic ablative body radiotherapy (SABR) utilizes technological advances to deliver highly precise, tumoricidal doses of radiation. There is an emerging body of literature on SABR in HCC demonstrating high rates of local control in the order of 80-90% at 3 years. SABR is associated with a low risk of radiation-induced liver disease or decompensation in appropriately selected HCC patients with compensated liver function and is now being incorporated into guidelines as an additional treatment option. This review outlines the emerging role of SABR in the multidisciplinary management of HCC and summarizes the current evidence for its use as an alternative ablative option for early-stage disease, as a bridge to transplant, and as palliation for advanced-stage disease. We outline specific considerations regarding patient selection, toxicities, and response assessment. Finally, we compare current international guidelines and recommendations for the use of SABR and summarize ongoing studies.

Abstract
BACKGROUND & AIMS A unique model of care was adopted in Australia following introduction of universal subsidised direct-acting antiviral (DAA) access in 2016 in order to encourage rapid scale-up of treatment. Community-based medical practitioners and integrated hepatitis nurses initiated DAA treatment with remote hepatitis specialist approval of the planned treatment without physical review. We aimed to evaluate outcomes of community-based treatment of hepatitis C (HCV) through this remote consultation process in the first 12 months of this model of care. METHODS A retrospective chart review of patients undergoing community-based HCV treatment from general practitioners and integrated hepatitis nurse consultants through the remote consultation model in three state jurisdictions in Australia from 1 March 2016 to 28 February 2017. RESULTS SVR12 was confirmed in 383/588 (65.1%) subjects intended for treatment with a median follow-up time of 12 months (IQR 9-14 months). The SVR12 test was not performed in 159/588 (27.0%) and 307/588 (52.2%) did not have liver biochemistry rechecked following treatment. Subjects who completed follow-up exhibited high SVR12 rates (383/392,97.7%). Nurse-led treatment was associated with higher confirmation of SVR12 (73.7% v 62.4%, p = 0.01) and liver biochemistry testing post treatment (57.5% v 45.0%, p = 0.01). CONCLUSIONS Community-based management of HCV through remote specialist consultation may be an effective model of care. Failure to check SVR12, recheck liver biochemistry and appropriate surveillance in patients with cirrhosis may emerge as significant issues requiring further support, education and refinement of the model to maximise effectiveness of future elimination efforts.

Abstract
BACKGROUND In clinical trials, HCV salvage treatment with Sofosbuvir/Velpatasvir/Voxilaprevir (SOF/VEL/VOX) achieved an SVR12 rate of >95% in NS5A-experienced participants. Lower SVR12 rates have been reported in real-world studies, particularly for genotype (GT)3 infection and cirrhosis. We determined the efficacy and safety of SOF/VEL/VOX in a large real-world cohort. METHODS We assessed the efficacy of salvage SOF/VEL/VOX for HCV infection in NS5A-inhibitor experienced participants with cirrhosis and portal hypertension, prior liver transplantation (LT) or severe extra-hepatic manifestations. SOF/VEL/VOX was available via an early access program. The primary outcome was SVR12. Secondary outcome was frequency of adverse events (AE). FINDINGS Ninety-seven participants were included. Median age was 58, 82% were male, 78% had cirrhosis, most with portal hypertension (61%, n=46/76), and 18% had prior-LT. Of the cirrhotic participants, 96% were Child-Turcotte-Pugh class A and 4% were class B. Of the 72% with GT3, 76% were also cirrhotic. By intention-to-treat analysis, SVR12 rate was 85% (n=82/97). Per protocol, the SVR12 rate was 90%, including 91% in GT1 (GT1a n=18/18, GT1b n=2/4), 89% in GT3 (n=59/66) and 100% in GT6 (n=3/3). SVR12 in participants with GT3 and cirrhosis was 90%. No predictors of non-SVR12 were identified. There were four serious AEs including one death and three hepatic decompensation events. NS5A resistance-associated substitutions detected at baseline did not affect SVR12. CONCLUSION This real-world study confirms high efficacy of SOF/VEL/VOX for the treatment of difficult-to-cure NS5A-inhibitor experienced patients, including those with GT3 and cirrhosis. Treatment was well tolerated in most however serious AEs can occur in those with advanced liver disease.

Abstract
BACKGROUND AND AIM Liver cirrhosis is a chronic disease complicated by recurrent hospital admissions. Self-management skills could facilitate optimal disease management. At present there is no validated instrument for measuring self-management in these patients. Hence, we evaluated the internal reliability and construct validity of the Partners in Health (PIH) scale, a chronic condition self-management tool in cirrhotic patients. METHODS In this prospective cohort study, the PIH scale was administered to 133 consenting patients within a Chronic Liver Failure Program of a tertiary hospital from February 2017 to May 2018. A Bayesian confirmatory factor analysis was used to evaluate a priori four-factor structure. Omega coefficients and 95% credible intervals (CrI) were used to assess internal reliability. Known-group validity was assessed in patients receiving active case management (n = 60) versus those without (n = 73). RESULTS The mean (± standard deviation (SD)) age of the participants was 62 (±11) years. Model fit for the hypothesised model was adequate (posterior predictive P-value = 0.073) and all hypothesised factor loadings were substantial (>0.6) and significant (P < 0.001). Omega coefficients (95% CrI) for the PIH subscales of Knowledge, Partnership, Management and Coping were 0.88 (0.82-0.91), 0.68 (0.57-0.76), 0.92 (0.89-0.94) and 0.89 (0.85-0.92) respectively. The mean (±SD) overall PIH score was higher in patients receiving case management compared to those without case management (81 ± 12 vs 73 ± 17, P < 0.001). CONCLUSION The dimensionality, known-group validity and reliability of the PIH scale for measuring self-management in patients with liver cirrhosis were confirmed. Its clinical predictive value requires further assessment.

Abstract
This study investigated the effect of recipient and donor genetic variability on dose-adjusted steady-state tacrolimus concentrations (Css ) and clinical outcomes 3 and 6 months after liver transplant. Twenty-nine recipients and matched donor blood samples were genotyped for 27 single nucleotide polymorphisms including CYP3A5*3 (rs776746), ABCB1 haplotype and immune genes. Associations between genetic variability and clinical parameters and Css and the occurrence of rejection and nephrotoxicity were analysed by multivariate and multinomial logistic regression modelling and Jonckheere-Terpstra tests examined the impact of combined donor/recipient CYP3A5 expression on Css . At 3 months post-transplant modelling revealed an association between tacrolimus Css and recipient CASP1 rs580523 genotype (P = 0.005), accounting for 52% Css variance. Jonckheere-Terpstra tests revealed that as combined donor/recipient CYP3A5 expression increased, Css decreased (P = 0.010 [3 months], 0.018 [6 months]). As this is the first report of CASP1 genetic variability influencing tacrolimus Css , further validation in larger cohorts is required.

Abstract
Screening and treatment for hepatitis C virus (HCV) infection were not prioritised in psychiatric patients due to adverse neuropsychiatric effects of interferon therapy despite reports of high prevalence. However, with the safe new antiviral drugs, HCV eradication has become a reality in these patients. The aim of this study was to report HCV seroprevalence, risk factors and treatment model in an Australian cohort. This prospective study involved patients admitted to four inpatient psychiatric units, from December 2016 to December 2017. After pretest counselling and consent, HCV testing was done; information on risk factors collected. A total of 260 patients (70% male), median age 44 years (IQR 24), were studied. The HCV seroprevalence was 10.8% (28/260) with 95% CI 7-15. Independent predictors of HCV positivity were injection drug use (P < 0.001, OR 44.05, 95% CI 7.9-245.5), exposure to custodial stay (P = 0.011, OR 7.34, 95% CI 1.6-33.9) and age (P = 0.011, OR 1.09, 95% CI 1.02-1.16). Eight of the 16 HCV RNA-positive patients were treated. Hepatitis nurses liaised with community mental health teams for treatment initiation and follow-up under supervision of hepatologists. Seven patients achieved sustained viral response, one achieved end of treatment response. The remaining eight patients were difficult to engage with. In conclusion, HCV prevalence was high in our cohort of psychiatric inpatients. Although treatment uptake was achieved only in 50% patients, it was successfully completed in all, with innovative models of care. These findings highlight the need to integrate HCV screening with treatment linkage in psychiatry practice.

Abstract
BACKGROUND Mycophenolate mofetil is a commonly used salvage therapy for patients with autoimmune hepatitis (AIH). AIM To evaluate the predictors of response to mycophenolate rescue therapy to facilitate clinical decision making. METHODS We performed a retrospective observational cohort study of AIH patients managed in 17 major Australian liver centres who received mycophenolate after an inadequate response or intolerance to corticosteroids with/without thiopurine(s). Baseline demographic, clinical and laboratory variables were compared between responders and nonresponders. A multivariable logistic regression model was developed using forward selection to identify independent predictors of treatment response. RESULTS A total of 105 patients received mycophenolate rescue therapy of whom 63 (60%) achieved biochemical remission. On univariable analysis, older age (P = 0.003), INR < 1.1 (P = 0.02), and lower immunoglobulin gamma (IgG; P < 0.002) levels were associated with treatment response, while no association was found with cirrhosis status (P = 0.07) or treatment indication (P = 0.63). On multivariable analysis, lower pre-treatment serum IgG level (P = 0.01), higher age at commencing mycophenolate (P = 0.01) and higher INR (P = 0.03) were the only significant independent predictors. An IgG level <17 g/L had a positive and negative predictive value for response of 71% and 60% respectively, while age ≥54 years when commencing mycophenolate had a positive and negative predictive value for response of 80% and 59% respectively. CONCLUSION Mycophenolate remains an excellent treatment option for patients with AIH refractory to or intolerant of standard therapy with those most likely to benefit being older and/or having lower pre-treatment IgG levels.

Abstract
The worldwide increase in obesity and diabetes has led to predictions that nonalcoholic steatohepatitis (NASH) will become the leading indication for orthotopic liver transplantation (OLT). Data supporting this prediction from outside the United States are limited. Thus, we aimed to determine trends in the frequency of NASH among adults listed and undergoing OLT in Australia and New Zealand (ANZ) from 1994 to 2017. Data from the ANZ Liver Transplant Registry were analyzed with patients listed for fulminant liver failure, retransplantation, or multivisceral transplants excluded. Nonparametric trend, Spearman rank correlation, and regression analysis were used to assess trends in etiologies of liver disease over time. Of 5016 patient wait-list registrants, a total of 3470 received an OLT. The percentage of patients with NASH activated for OLT increased significantly from 2.0% in 2003 to 10.9% in 2017 (trend analyses; P < 0.001). In 2017, NASH was the third leading cause of chronic liver disease (CLD) among wait-list registrants behind chronic hepatitis C virus (HCV; 29.5%) and alcohol (16.1%). Similarly, significant increases over time in the percentage of patients undergoing OLT were observed for HCV and NASH (all trend analyses; P < 0.001) but with significant reductions in primary sclerosing cholangitis and cryptogenic cirrhosis (both P < 0.05). By 2017, NASH was the third leading cause of liver disease among patients undergoing OLT (12.4%) and behind chronic HCV (30.2%) and alcohol (18.2%). NASH also became the third most frequent etiology of CLD in patients transplanted (13.8%) with concomitant hepatocellular carcinoma by 2017. In conclusion, NASH is increasing as a primary etiology of liver disease requiring listing and liver transplantation in ANZ.

Abstract
In March 2016, the Australian government offered unrestricted access to direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) to the entire population. This included prescription by any medical practitioner in consultation with specialists until sufficient experience was attained. We sought to determine the outcomes and experience over the first twelve months for the entire state of South Australia. We performed a prospective, observational study following outcomes of all treatments associated with the state's four main tertiary centres. A total of 1909 subjects initiating DAA therapy were included, representing an estimated 90% of all treatments in the state. Overall, SVR12 was 80.4% in all subjects intended for treatment and 95.7% in those completing treatment and follow-up. 14.2% were lost to follow-up (LTFU) and did not complete SVR12 testing. LTFU was independently associated with community treatment via remote consultation (OR 1.50, 95% CI 1.04-2.18, P = .03), prison-based treatment (OR 2.02, 95% CI 1.08-3.79, P = .03) and younger age (OR 0.98, 95% CI 0.97-0.99, P = .05). Of the 1534 subjects completing treatment and follow-up, decreased likelihood of SVR12 was associated with genotype 2 (OR 0.23, 95% CI 0.07-0.74, P = .01) and genotype 3 (OR 0.23, 95% CI 0.12-0.43, P ≤ .01). A significant decrease in treatment initiation was observed over the twelve-month period in conjunction with a shift from hospital to community-based treatment. Our findings support the high responses observed in clinical trials; however, a significant gap exists in SVR12 in our real-world cohort due to LTFU. A declining treatment initiation rate and shift to community-based treatment highlight the need to explore additional strategies to identify, treat and follow-up remaining patients in order to achieve elimination targets.

Abstract
Severe alcoholic hepatitis (sAH) is associated with a poor prognosis. There is no proven effective treatment for sAH, which is why early transplantation has been increasingly discussed. Hepatoblastoma-derived C3A cells express anti-inflammatory proteins and growth factors and were tested in an extracorporeal cellular therapy (ELAD) study to establish their effect on survival for subjects with sAH. Adults with sAH, bilirubin ≥8 mg/dL, Maddrey's discriminant function ≥ 32, and Model for End-Stage Liver Disease (MELD) score ≤ 35 were randomized to receive standard of care (SOC) only or 3-5 days of continuous ELAD treatment plus SOC. After a minimum follow-up of 91 days, overall survival (OS) was assessed by using a Kaplan-Meier survival analysis. A total of 203 subjects were enrolled (96 ELAD and 107 SOC) at 40 sites worldwide. Comparison of baseline characteristics showed no significant differences between groups and within subgroups. There was no significant difference in serious adverse events between the 2 groups. In an analysis of the intent-to-treat population, there was no difference in OS (51.0% versus 49.5%). The study failed its primary and secondary end point in a population with sAH and with a MELD ranging from 18 to 35 and no upper age limit. In the prespecified analysis of subjects with MELD < 28 (n = 120), ELAD was associated with a trend toward higher OS at 91 days (68.6% versus 53.6%; P = .08). Regression analysis identified high creatinine and international normalized ratio, but not bilirubin, as the MELD components predicting negative outcomes with ELAD. A new trial investigating a potential benefit of ELAD in younger subjects with sufficient renal function and less severe coagulopathy has been initiated. Liver Transplantation 24 380-393 2018 AASLD.

Abstract
BACKGROUND Antiviral therapy for hepatitis C has the potential to improve liver function in patients with decompensated cirrhosis. AIMS To examine the virological response and effect of viral clearance in patients with decompensated hepatitis C cirrhosis all with MELD scores ≥15 following sofosbuvir/daclatasvir ± ribavirin. METHODS We prospectively collected data on patients who commenced sofosbuvir/daclatasvir for 24-weeks under the Australian patient supply program (TOSCAR) and analysed outcomes including sustained viral response at 12 weeks (SVR12), death and transplant. RESULTS 108 patients (M/F, 79/29; median age 56years; Child-Pugh 10; MELD 16; genotype 1/3, 55/47) received sofosbuvir/daclatasvir and two also received ribavirin. On intention-to-treat, the SVR12 rate was 70% (76/108). Seventy-eight patients completed 24-weeks therapy. SVR12 was achieved in 56 of these patients on per-protocol-analysis (76%). SVR12 was 80% in genotype 1 compared to 69% in genotype 3. Thirty patients failed to complete therapy. In patients achieving SVR12, median MELD and Child-Pugh fell from 16(IQR15-17) to 14(12-17) and 10(9-11) to 8(7-9), respectively (P<.001). In those who died, MELD increased from 16 to 23 at death (P=.036). Patients who required transplantation had a significantly higher baseline MELD (20) compared to those patients completing treatment (16) (P=.0010). The odds ratio for transplant in patients with baseline MELD ≥20 was 13.8(95%CI 2.78-69.04). CONCLUSIONS SVR12 rates with sofosbuvir/daclatasvir in advanced liver disease are lower than in compensated disease. Although treatment improves MELD and Child-Pugh in most patients, a significant proportion will die or require transplantation. In those with MELD ≥20, it may be better to delay treatment until post-transplant.

Abstract
BACKGROUND & AIMS Little is known about outcomes of patients with autoimmune hepatitis (AIH) who have a suboptimal outcome to standard therapy and are then given mycophenolate mofetil as rescue therapy. We evaluated the efficacy and safety of mycophenolate mofetil in patients failed by or intolerant to corticosteroids, with or without azathioprine. METHODS We performed a retrospective study of 105 patients with AIH who received mycophenolate mofetil therapy after an inadequate response or intolerance to standard therapy (98% received combination therapy with corticosteroids plus thiopurines). Patients were recruited from 17 liver clinics via the Australian Liver Association Clinical Research Network. We reviewed records for baseline demographic features and characteristics of liver disease, initial therapy, mycophenolate mofetil indications, treatment outcome, and side effects. The primary outcome was biochemical remission, defined as levels of alanine and aspartate transferase and IgG level within the normal reference range, with or without normal liver histology within the first 2 years of treatment. RESULTS The indication for mycophenolate mofetil therapy was non-response to treatment for 40% of cases and intolerance to therapy for 60%. Overall, 63 patients (60%) achieved biochemical remission following a median 12 weeks treatment with mycophenolate mofetil. The proportion of patients who achieved biochemical remission was similar between patients receiving mycophenolate mofetil for non-response to standard therapy (57%) and patients with intolerance to standard therapy (62%). However, a lower proportion of patients with cirrhosis achieved biochemical remission (47%) than patients without cirrhosis (6%) (P = .07). Serious adverse events occurred in 3 patients (2.7%) including 1 death, and 10 patients (9.2%) discontinued mycophenolate mofetil because of adverse events. CONCLUSION In this retrospective study of patients with AIH who received mycophenolate mofetil as a rescue therapy, we found the drug to be well tolerated and moderately effective, inducing biochemical remission in 60% of subjects. Rates of response are lower and rates of infection are higher in patients with AIH and cirrhosis. Prospective studies of mycophenolate mofetil are warranted for this population.

Abstract
BACKGROUND Hepatitis C (HCV), hepatitis B (HBV), alcohol-related liver disease (ALD), and non-alcohol-related fatty liver disease (NAFLD) are leading indications for adult liver transplantation in Australia and New Zealand. However, these diseases are potentially preventable through effective primary and/or secondary prevention strategies. This study evaluates the relative contribution of potentially preventable liver diseases to liver transplant numbers in Australia and New Zealand over time. METHODS Prospectively recorded clinical, demographic, and outcome data were collected from the Australian and New Zealand Liver Transplant Registry for all primary adult liver transplants performed in Australia and New Zealand from 1 January 1985 until 31 December 2012. Potentially preventable liver disease was defined as HBV, HCV, NAFLD, ALD, and HCC. The etiology of liver disease leading to liver transplantation and the proportion of preventable liver disease-related liver transplantation was compared between Era 1 (1985-1993), Era 2 (1994-2003), and Era 3 (2004-2012). RESULTS Overall, 1252 of 3266 adult primary liver transplants (38.3%) were performed for potentially preventable liver disease. There was a significant increase in the proportion of liver transplants because of preventable liver disease from 21.2% (93 of 439) in Era 1, to 49.8% (623 of 1252) in Era 2 and 63.5% (1000 of 1575) in Era 3 (P < 0.0001). Over time, there was a significant increase in HCV (P < 0.0001), ALD (P = 0.002), and NAFLD (P < 0.0001) as a primary indication for adult liver transplant, whereas HBV has significantly decreased from Era 1 to Era 3 as an indication for transplant (P < 0.0001). The number of transplants performed for HCC also increased across Eras (P < 0.0001), with 84% due to underlying potentially preventable liver disease. CONCLUSION Since 2004, the majority of primary adult liver transplants within Australia and New Zealand have been because of potentially preventable liver diseases and the prevalence of these diseases has increased over time. This finding represents an opportunity for clinicians to make a significant impact on the overall burden of advanced liver disease in Australia and New Zealand by improving primary and secondary prevention measures.

Abstract
AIM: To examined the efficacy and safety of treatment with boceprevir, PEGylated-interferon and ribavirin (PR) in hepatitis C virus genotype 1 (HCVGT1) PR treatment-failures in Asia.
METHODS: The Boceprevir Named-Patient Program provided boceprevir to HCVGT1 PR treatment-failures. Participating physicians were invited to contribute data from their patients: baseline characteristics, on-treatment responses, sustained virological response at week 12 (SVR12), and safety were collected and analysed. Multivariate analysis was performed to determine predictors of response.
RESULTS: 150 patients were enrolled from Australia, Malaysia, Singapore and Thailand (Asians = 86, Caucasians = 63). Overall SVR12 was 61% (Asians = 59.3%, Caucasians = 63.5%). SVR12 was higher in relapsers (78%) compared with non-responders (34%). On-treatment responses predicted SVR, with undetectable HCVRNA at week 4, 8 and 12 leading to SVR12s of 100%, 87%, and 82% respectively, and detectable HCVRNA at week 4, 8 and 12, leading to SVR12s of 58%, 22% and 6% respectively. Asian patients were similar to Caucasian patients with regards to on-treatment responses. Patients with cirrhosis (n = 69) also behaved in the same manner with regards to on-treatment responses. Those with the IL28B CC genotype (80%) had higher SVRs than those with the CT/TT (56%) genotype (P = 0.010). Multivariate analysis showed that TW8 and TW12 responses were independent predictors of SVR. Serious adverse events occurred in 18.6%: sepsis (2%), decompensation (2.7%) and blood transfusion (14%). Discontinuations occurred in 30.7%, with 18.6% fulfilling stopping rules.
CONCLUSION: Boceprevir can be used successfully in PR treatment failures with a SVR12 > 80% if they have good on-treatment responses; however, discontinuations occurred in 30% because of virological failure or adverse events.

Abstract
Despite the widespread use of locoregional therapies [radiofrequency ablation and transarterial chemoembolization (TACE)], there is currently a lack of high-quality evidence supporting their use for hepatocellular carcinoma (HCC) in patients on the liver transplantation (LT) waiting list or requiring down-staging. Radiotherapy has rarely been used in this setting and has usually been in the form of more complex and less accessible techniques such as proton-beam and stereotactic body radiation therapy. Only 1 report describes the use of conventional 3-dimensional conformal external-beam radiotherapy (cEBRT) techniques as neoadjuvant or down-staging therapy for patients who are LT candidates. This report describes the use of cEBRT in a 52-year-old hepatitis C-positive man with cirrhosis. A 40-mm right lobe HCC was treated initially with TACE while he was on the waiting list. The lesion progressed beyond transplant criteria (76 mm). Conventional external-beam radiotherapy (EBRT) was used (54 Gy in 27 fractions) to down-stage the lesion. EBRT was well tolerated and resulted in a complete radiological response with no arterial enhancement of the lesion for a total of 16 months. Subsequent LT and a review of the explant demonstrated complete histological necrosis of the lesion. This report provides the first description of complete histological necrosis of HCC through the use of cEBRT techniques as down-staging/neoadjuvant therapy before LT. Because of its potential efficacy, accessibility, tolerability, noninvasive and outpatient nature, and ability to treat lesions adjacent to vessels and biliary structures, further trials examining the efficacy of cEBRT versus other neoadjuvant techniques are urgently required.

Abstract
The lysosomal cysteine protease cathepsin B has been studied intensely for many years because of its unique characteristics and its potential involvement in disease states. A reproducible, high yield expression system for active recombinant protein is key to biochemical and biophysical studies as well as rational drug design. Although several microbial and mammalian expression systems for recombinant human cathepsin B have been described, these have been limited by low or variable yields. Further, in some of these systems hyper-glycosylation of the enzyme near the active site affects its activity. We describe a baculovirus expression system and purification scheme that solve all of these problems. Yields of active, protected enzyme were reproducibly in excess of 25 mg/L. Since this protein was not hyper-glycosylated, it had greater activity than cathepsin B produced in yeast systems as indicated by a threefold increase in Kcat. In addition, the biophysical properties of the baculovirus-expressed cathepsin B, as measured by dynamic light scattering, were more amenable to crystallographic study since the data indicated proteins of more uniform size. Therefore, this system for the production of recombinant human cathepsin B constitutes a major improvement in both quantity and quality over those previously reported. Further, we demonstrate that the manner of expression and purification of this enzyme has profound effects on its kinetic and physical parameters.
