Asterixis.

Adams and Foley described asterixis in the 1940s in patients with hepatic encephalopathy, but it has since been associated with a wide range of potential causes, both in neurology and general medicine. Here, we review the history, characteristics and clinical significance of this important clinical sign.

Major variation in hepatocellular carcinoma treatment and outcomes in England: a retrospective cohort study.

Objective: Hepatocellular carcinoma (HCC) is increasingly incident in England, while survival remains poor with regional disparities. We aimed to explore the differences in HCC treatment across different geographical regions and to examine the impact on cancer survival. Methods: Incident HCC cases and treatment were identified from the English Hospital Episode Statistics (2016-2017) and then a subset by National Health Service (NHS) regions. Treatment was grouped into curative, palliative and untreated. Median survival was estimated to date of death in the national statistics. Results: The median observed survival was 8.6 months (95% CI 7.5 to 9.9) across all 2160 HCC cases, 52.1 months (CI 50.5, not reached) in 449 (20.8%) treated with curative intent, 21.0 months (CI 18.5 to 24.5) after other cancer-specific treatment in 449 (20.8%), and 2.3 months (CI 2.1 to 2.6) in 1262 (58.4%) untreated. Across NHS regions, <50% of cases received treatment (30.4%-49.6%), while between 14.2% and 27.7% had curative treatment. The 3-year survival was similar (23.5%-29.7%), except in the London region (40.0%). Conclusion: Majority of HCC cases in England are untreated and survival remains low, with variation in outcomes in regions with similar incident rates. A deeper exploration of regional treatments and screening practice is required to improve early detection and survival.

Outcomes of National Survey of the Practice of Hepatocellular Carcinoma Surveillance.

Background & Aim: HCC has significantly improved outcomes when detected early. Guidelines recommend biannual surveillance with ultrasound (US) and/or AFP in at-risk individuals. This survey aimed to describe HCC surveillance adherence/practices amongst the NHS hospitals in the UK. Methods: An electronic survey was sent to 79 NHS hospitals via the British Association for the Study of the Liver distribution list. The responses were captured from July 2021 to January 2022. Centres were divided into hepato-pancreato-biliary (HPB) and non-HPB centres, depending on whether the hospital undertakes major liver surgeries. Results: A total of 39 (49.3%) centres responded: 15 HPB and 24 non-HPB centres from across the UK. HCC surveillance eligibility criteria were universally applied, but heterogeneous approaches occur outside these criteria. Eighty per cent of patients undergoing surveillance were estimated to have cirrhosis. Eighty-five per cent of centres do 6-monthly US and AFP requested by clinicians and liver clinical nurse specialists. Compliance was estimated at 80% but not routinely audited. In most centres, general sonographers and/or radiologists perform surveillance US scans without a standard reporting template, although structured reporting was viewed as desirable by the majority. Poor views on US are approached heterogeneously, with patients variably offered ongoing US, CT, or MRI with different protocols. Conclusion: Most responding NHS hospitals follow 6-monthly HCC surveillance guidance. Data recording is variable, with limited routine data collection regarding compliance, yield, and quality. Surveillance US is mostly performed by non-HPB specialists without standardised reporting. There is an inconsistent approach to poor views with US surveillance. Even in a universal healthcare system such as NHS, which is free at the point of care, delivery of HCC surveillance has not improved over the last decade and remains variable.

Cost of hepatocellular carcinoma to the national health service in England: a registry-based analysis.

OBJECTIVE: Hepatocellular carcinoma (HCC) incidence in the UK trebled between 1997 and 2017. With increasing numbers requiring treatment, understanding the likely impact on healthcare budgets can inform service planning and commissioning. The aim of this analysis was to use existing registry data to describe the direct healthcare costs of current treatments for HCC and estimate the impact on National Health Service (NHS) budgets. DESIGN: A retrospective data analysis based on the National Cancer Registration and Analysis Service cancer registry informed a decision-analytic model for England comparing patients by cirrhosis compensation status and those on palliative or curative treatment pathways. Potential cost drivers were investigated by undertaking a series of one-way sensitivity analyses. RESULTS: Between 1 January 2010 and 31 December 2016, 15 684 patients were diagnosed with HCC. The median cost per patient over 2 years was £9065 (IQR: £1965 to £20 491), 66% did not receive active therapy. The cost of HCC treatment for England over 5 years was estimated to be £245 million. CONCLUSION: The National Cancer Registration Dataset and linked data sets have enabled a comprehensive analysis of the resource use and costs of secondary and tertiary healthcare for HCC, providing an overview of the economic impact to the NHS England of treating HCC.

Digital image analysis of liver collagen predicts clinical outcome of recurrent hepatitis C virus 1 year after liver transplantation.

Clinical outcomes of recurrent hepatitis C virus after liver transplantation are difficult to predict. We evaluated collagen proportionate area (CPA), a quantitative histological index, at 1 year with respect to the first episode of clinical decompensation. Patients with biopsies at 1 year after liver transplantation were evaluated by Ishak stage/grade, and biopsy samples stained with Sirius red for digital image analysis were evaluated for CPA. Cox regression was used to evaluate variables associated with first appearance of clinical decompensation. Receiver operating characteristic (ROC) curves were also used. A total of 135 patients with median follow-up of 76 months were evaluated. At 1 year, median CPA was 4.6% (0.2%-36%) and Ishak stage was 0-2 in 101 patients, 3-4 in 23 patients, and 5-6 in 11 patients. Decompensation occurred in 26 (19.3%) at a median of 61 months (15-138). Univariately, CPA, tacrolimus monotherapy, and Ishak stage/grade at 1 year were associated with decompensation; upon multivariate analysis, only CPA was associated with decompensation (P = 0.010; Exp(B) = 1.169; 95%CI, 1.037-1.317). Area under the ROC curve was 0.97 (95%CI, 0.94-0.99). A cutoff value of 6% of CPA had 82% sensitivity and 95% specificity for decompensation. In the 89 patients with hepatic venous pressure gradient (HVPG) measurement, similar results were obtained. When both cutoffs of CPA > 6% and HVPG ≥ 6 mm Hg were used, all patients decompensated. Thus, CPA at 1-year biopsy after liver transplantation was highly predictive of clinical outcome in patients infected with hepatitis C virus who underwent transplantation, better than Ishak stage or HVPG.

Halting the haematochezia.

An elderly gentleman with primary sclerosing cholangitis (PSC) was admitted with rectal bleeding, shown on flexible sigmoidoscopy to be arising from rectal varices, which bled despite endoscopic therapy with histoacryl glue. Therapeutic options were limited with surgery and transjugular intrahepatic portosystemic shunt deemed too high risk, and endovascular embolisation through interventional radiology was sought. Coil-assisted retrograde transvenous obliteration was used to good effect. This rare approach has advantages over balloon occlusion, avoiding long indwelling balloon time and risk of rupture or infection, as well as time efficiency.

Primary liver cancer in the UK: Incidence, incidence-based mortality, and survival by subtype, sex, and nation.

BACKGROUND & AIMS: The incidence of primary liver cancer (PLC) is increasing in Western Europe. To understand trends over time and the current burden in the UK, a detailed analysis of the epidemiology of PLC and its subtypes was conducted. METHODS: Data on PLCs diagnosed during 1997-2017 were obtained from population-based, nationwide registries in the UK. European age-standardised incidence (ASR) and incidence-based mortality rates (ASMR) per 100,000 person-years were calculated overall and by sex and UK-nation. Annual percentage change in rates was estimated using Joinpoint regression. One-, 2-, and 5-year age-standardised net survival was estimated. RESULTS: A total of 82,024 PLCs were diagnosed. Both hepatocellular carcinoma (HCC) incidence and mortality rates trebled (ASR 1.8-5.5 per 100,000, ASMR 1.3-4.0). The rate of increase appeared to plateau around 2014/2015. Scottish men consistently had the highest HCC incidence rates. PLC survival increased, driven by a substantial increase in the proportion that are HCC (as prognosis is better than other PLCs) and in HCC survival (change in 1-year survival 24-47%). Intrahepatic cholangiocarcinoma was the most common PLC in women and 1-year survival improved from 22.6% to 30.5%. CONCLUSIONS: PLC incidence has been increasing rapidly but, as most risk factors are modifiable, it is largely a preventable cancer. This rate of increase has slowed in recent years, possibly attributable to effective treatment for hepatitis C. As other risk factors such as obesity and diabetes remain prevalent in the UK, it is unlikely the considerable burden of this disease will abate. While improvements in survival have been made, over half of patients are not alive after 1 year, therefore further progress in prevention, early detection, and treatment innovation are needed. LAY SUMMARY: Many more people are getting liver cancer, particularly the subtype hepatocellular carcinoma, than 20 years ago. Men in Scotland are most likely to get liver cancer and to die from it. Survival after liver cancer diagnosis is getting longer but still less than half are alive after 1 year.

Hepatic dysfunction in sickle cell disease: a new system of classification based on global assessment.

BACKGROUND & AIMS: Hepatic dysfunction in adults with sickle cell disease varies in character and severity from self-limited cholestasis to life-threatening acute liver failure and cirrhosis. Because previous attempts to describe patterns of liver disease have not reflected clinical experience, we aimed to characterize the presentation, clinicopathologic findings, and natural history of such patients. METHODS: We reviewed the clinical, laboratory, radiographic, and histologic features with the natural history of 38 patients (mean age, 33 years) with Hb SS, SC, or S-beta thalassemia referred to a tertiary liver center for assessment. RESULTS: Distinct disease patterns were identified that comprised massive hepatocellular necrosis (5%), acute severe sequestration and cholestasis in the context of sepsis (18%), cirrhosis (18%), chronic, fluctuating sequestration without cholestasis (21%), mechanical biliary obstruction (8%), siderosis without cirrhosis (8%), generalized cholangiopathy (8%), venous outflow obstruction (3%), and miscellaneous (11%). Of the 20 who required emergency admission, 8 did not survive their index admission, and 3 patients died during follow-up admissions (4 months-4 years later). There were 3 instances of hemorrhage related to liver biopsy. One patient underwent transplantation but died. Hematologic and biochemical markers did not discriminate well between survivors and nonsurvivors. The incidence of a second hepatic pathology (ie, viral hepatitis, autoimmune disease, transfusional siderosis) was 37% and was associated with the finding of more advanced histologic fibrosis. CONCLUSIONS: Patterns of hepatic dysfunction in sickle cell disease are diverse and demand clear characterization for each individual; however, groups with a poor prognosis can be identified after collation of clinical, laboratory, and radiologic data. Findings at biopsy (which is associated with higher risk of bleeding in this group) might be anticipated by noninvasive test results.
