We investigated the possible link between liver cirrhosis and gallstone risk in chronic hepatitis C (CHC) patients in China.To analyze the association between liver cirrhosis and gallstone development, we compared outcomes of 133 Chinese CHC patients with gallstones and an age-, sex-, and hepatitis C virus RNA level-matched control group of 431 CHC patients without gallstones.We found that liver cirrhosis was more prevalent in gallstone patients (40.6%) than in the control group (24.4%). Logistic regression analyses adjusting for demographic features and other gallstone risk factors revealed that liver cirrhosis increased the risk of gallstone development 2-fold (adjusted odds ratio [AOR]: 2.122; 95% confidence interval [CI]: 1.408-3.198). Moreover, multivariate analyses comparing the risk of gallstone development in liver cirrhosis patients with decompensated or compensated liver cirrhosis yielded an estimated AOR (95% CI) of 2.869 (1.277-6.450) in patients with decompensated liver cirrhosis. Gallstone risk also increased significantly with older age (>60 years) (AOR: 2.019; 95% CI: 1.017-4.009).Liver cirrhosis significantly correlates with increased risk of gallstone development in CHC patients in China. Decompensated liver cirrhosis and older age further heighten this risk in patients diagnosed with hepatitis C-related cirrhosis.

The present study aims to assess the efficacy and safety of ultrasound-guided percutaneous microwave ablation (MWA) for hepatic alveolar echinococcosis (HAE) preliminarily.Seventeen patients diagnosed to HAE and treated with MWA (80 watts, 4 min) were retrospectively analyzed. The upper abdominal computed tomography (CT) was performed at 1, 6, 12 months after the MWA treatment. The complications were evaluated to assess the safety.The diameters of the lesions in the HAE patients ranged from 1.9 to 4.7 cm. The patients included 10 males and 7 females, aged 26 to 70 (45.82 ± 13.36) years, 5 patients infecting with chronic hepatitis viral B and 8 patients with positive hydatid antibody (IgG). The lesions observed in the postoperative CT (1, 6, 12 months) were calcified compared with those observed in the preoperative CT and without relapse. No serious treatment-related complications occurred after treatment.MWA is a novel and effective therapeutic method for HAE with a single lesion (diameter≤=5 cm). Further studies based on prospective random control trials to confirm our findings are necessary.

Protein induced by vitamin K absence-II (PIVKA-II) is a potential screening marker for hepatocellular carcinoma (HCC). Limited data are available about its utility in discriminating neoplastic from regenerative nodules at ultrasonography (US) evaluation in cirrhotic patients. Aim of this study was to investigate the diagnostic utility of PIVKA-II in cases showing liver nodules of uncertain diagnosis at US.Ninety cirrhotics with US evidence of liver nodule(s) were enrolled. All patients underwent blood sampling within 1 week of US and were thereafter followed up. HCC was confirmed in 40/90 cases, and in all cases it was in a very early/early stage. All sera were tested for PIVKA-II and alpha-fetoprotein (AFP) at the end of follow-up. PIVKA-II at a cut off of 60 mAU/mL was significantly associated with HCC at both univariate and multivariate analysis (P = .016 and P = .032, respectively). AFP at a cut off of 6.5 ng/mL was not associated with HCC at univariate analysis (P = .246). ROC curves showed that PIVKA-II had 60% sensitivity, 88% specificity, 80% positive predictive value (PPV), and 73% negative predictive value (NPV), whereas AFP had 67% sensitivity, 68% specificity, 63% PPV, and 72% NPV. AUROC curves showed that the combination of both biomarkers increased the diagnostic accuracy for HCC (AUC 0.76; sensitivity 70%, specificity 94%, PPV 91%, and NPV 79%).In conclusion, PIVKA-II is a useful tool for the diagnostic definition of US-detected liver nodules in cirrhotic patients, and it provides high diagnostic accuracy for HCC when combined with AFP.

An observational study describing the number and type of chronic conditions and medications taken by diabetic patients with NAFLD and identifying characteristics that may impact liver disease severity or clinical management.Adults with type 2 diabetes have a high prevalence of nonalcoholic fatty liver disease (NAFLD) and increased risk of developing advanced liver disease. Appropriate management should consider the characteristics of the diabetic NAFLD population, as comorbid conditions and medications may increase the complexity of treatment strategies.Diabetic patients with NAFLD at risk of clinically significant liver disease (as assessed by the FIB-4 or NAFLD fibrosis scores) were recruited consecutively from the Endocrine clinic or primary care. Medical conditions, medication history, anthropometric measurements, and laboratory tests were obtained during assessment. NAFLD severity was classified by transient elastography and liver ultrasound into "no advanced disease" (LSM < 8.2 kPa) or "clinically significant liver disease" (LSM ≥ 8.2 kPa).The most common coexistent chronic conditions were metabolic syndrome (94%), self-reported "depression" (44%), ischaemic heart disease (32%), and obstructive sleep apnoea (32%). Polypharmacy or hyperpolypharmacy was present in 59% and 31% of patients respectively. Elevated LSM (≥ 8.2 kPa) suggesting significant liver disease was present in 37% of this at-risk cohort. Increasing obesity and abdominal girth were both independently associated with likelihood of having significant liver disease.There is a high burden of multimorbidity and polypharmacy in diabetic NAFLD patients, highlighting the importance of multidisciplinary management to address their complex health care needs and ensure optimal medical treatment.

BACKGROUND & AIMS: Little is known about the absolute risk of hepatocellular carcinoma (HCC) and liver-disease related death, in association with metabolic risk factors, for patients with hepatitis B virus (HBV) infection. METHODS: We collected data from 5373 male Taiwanese civil servants who visited Taiwan's Government Employees' Central Clinics and received routine free physical examinations from 1989 through 1992. We obtained information on liver-related morbidity and mortality in HBV carriers, 40-65 years old (n=1690), with different metabolic risk factors. We compared their medical histories with those of study participants without HBV or HCV infection in the same age range (n=1289). We used patients' baseline data on obesity, diabetes, hypertriglyceridemia, and high blood pressure to assign them to metabolic risk categories. We then performed a case-cohort analysis of the effects of hepatitis B viral factors on risk for HCC, based on metabolic factors and insulin resistance. RESULTS: Over median follow-up period of 19 years, 158 of the 1690 HBV carriers developed HCC and 126 died from liver-related diseases. Among participants without HBV or HCV infection, only 6 developed HCC or died from liver-related disease. HBV carriers with different metabolic risk factors had significant differences in cumulative incidence of HCC and liver-related death. Patients with 3 or more metabolic risk factors had a substantially higher risk for HCC (10-year cumulative incidence, 13.60%) than patients with a low metabolic risk profile (10-year cumulative incidence, 4.83%; adjusted-hazard ratio [aHR], 2.32; 95% CI, 1.18-4.54). Smoking had a significant effect on this association (Pinteraction = .0044). Having 3 or more metabolic risk factors, compared with no factors, significantly increased the risk of HCC (aHR, 5.06; 95% CI, 2.23-11.47) and 10-year cumulative incidence of HCC (25.0% in smokers with 3 or more metabolic risk factors vs 3.87% in smokers with none; P< .0001) in smokers, but did not increase risk of HCC in nonsmokers. Metabolic risk factors and insulin resistance had the largest effect on HCC risk in patients with levels of HBV-DNA <10000 copies/mL. CONCLUSIONS: In a study of men with chronic HBV infection ages 40-65 years in Taiwan, we associated a high burden of metabolic risk factors with increased risk of HCC; smoking has a significant effect on this association.

To estimate the effect of hepatitis C virus (HCV) coinfection on the development of complications and progression of human immunodeficiency virus (HIV) disease among HIV-infected elite controllers.Single-center retrospective cohort. Kaplan-Meier methods, prevalence ratios, and Cox proportional-hazards models were used.In all, 55 HIV-infected elite controllers were included in this study. Among them, 45% were HIV/HCV coinfected and 55% were HIV mono-infected. Median follow-up time for the cohort was 11 years. Twenty-five patients experienced a complication and 16 lost elite controller status during the study period. HCV coinfected patients were 4.78 times (95% confidence interval 1.50-15.28) more likely to develop complications compared with HIV mono-infected patients. There was no association between HCV coinfection status and loss of elite control (hazard ratio 0.75, 95% confidence interval 0.27-2.06).Hepatitis C virus coinfection was significantly associated with the risk of complications even after controlling for sex, injecting drug use, and older age. HCV coinfected patients had higher levels of cellular activation while also having similar levels of lipopolysaccharide and soluble CD14. HCV coinfection was not associated with loss of elite controller status. Taken together, this suggests that HCV coinfection does not directly affect HIV replication dynamics or natural history, but that it may act synergistically with HIV to produce a greater number of associated complications. Continued follow-up will be needed to determine whether HCV cure through the use of direct-acting antivirals among HIV/HCV coinfected elite controllers will make the risk for complications among these patients similar to their HIV mono-infected counterparts.

We evaluated the cost-effectiveness of two alternative DAA treatment policies in a real-life cohort of HCV-infected patients: Policy 1 - "universal": treat all patients, regardless of the fibrosis stage; Policy 2 - treat only "prioritized" patients, delay treatment of the remaining patients until reaching stage F3. A liver disease progression Markov model, which used a lifetime horizon and healthcare system perspective, was applied to the PITER cohort (representative of Italian HCV-infected patients in care). Specifically, 8,125 patients naïve to DAA treatment, without clinical, sociodemographic or insurance restrictions was used to evaluate the policies' cost-effectiveness. The patients' age, fibrosis stage, assumed DAA treatment cost of €15,000/patient and the Italian liver disease costs were used to evaluate Quality-Adjusted Life-Years (QALY) This article is protected by copyright.

OBJECTIVE: The purpose of this study is to evaluate the outcomes of hypovascular hypointense nodules in the hepatobiliary phase of gadoxetic acid-enhanced MRI and the risk factors for the hypervascular transformation of the nodules through a systematic review and meta-analysis. MATERIALS AND METHODS: We searched the Ovid-MEDLINE and EMBASE databases for published studies of hypovascular hypointense nodules in patients with chronic liver disease. The pooled proportions of the overall and cumulative incidence rates at 1, 2, and 3 years for the transformation of hypovascular hypointense nodules into hypervascular hepatocellular carcinomas (HCCs) were assessed by using random-effects modeling. Metaregression analysis was performed. RESULTS: Sixteen eligible studies with 944 patients and 1819 hypovascular hypointense nodules in total were included. The pooled overall rate of hypervascular transformation was 28.2% (95% CI, 22.7-33.6%; I(2) = 87.46%). The pooled 1-, 2-, and 3-year cumulative incidence rates were 18.3% (95% CI, 9.2-27.4%), 25.2% (95% CI, 12.2-38.2%), and 30.3% (95% CI, 18.8-41.9%), respectively. The metaregression analysis revealed that the mean initial nodule size (cutoff value, 9 mm) was a significant factor affecting the heterogeneity of malignant transformation. CONCLUSION: Hypovascular hypointense nodules detected in the hepatobiliary phase of gadoxetic acid-enhanced MRI carry a significant potential of transforming into hypervascular HCCs. The size of nodules is a significant risk factor for hypervascular transformation.

Chronic hepatitis B virus (HBV) infection remains a global problem. Several HBV (sub)genotypes exist with different biology and geographical preponderances. While the future aim of HBV treatment remains virus eradication, current strategies of treatment aim to suppress the virus and prevent the progression of liver disease. Current strategies also involve identification of patients for treatment - those at risk of progressive liver disease. Identification of HBV genotype, HBV mutants and other predictive factors allow for tailored treatments, and also risk-surveillance pathways such as for hepatocellular cancer screening. In the future, these factors may allow stratification of not only treatment decisions, but also identify patients at risk of higher relapse rates when current therapies may be discontinued. Newer technologies, such as next generation sequencing to assess drug-resistant or immune escape variants and quasi-species heterogeneity in patients before and during treatment, may allow for more information-based treatment decisions between the clinician and the patient. This article serves to discuss how HBV (sub-)genotypes and genetic variants play a role in not only the disease course and outcomes, but also in how current treatment strategies can be influenced by them. Adopting a personalized approach per genotype may play a role in future strategies in combatting the disease. This article also discusses new technologies in the battle against HBV that may allow more informed decisions about treatment modifications such as response guided therapy.

OBJECTIVES: The aim of this study was to investigate the quality of ultrasound (US) examinations for hepatocellular carcinoma surveillance under the Korean National Cancer Screening Program and to assess knowledge and experience about liver US of physicians who perform US examinations. METHODS: The investigation about the quality of liver US for hepatocellular carcinoma screening was based on the results of a nationwide quality assurance (QA) evaluation between 2012 and 2014 at all medical institutions participating in the National Cancer Screening Program. The QA evaluation was for personnel, equipment, education, and clinical images. Medical institutions with fewer than 60 of 100 points were considered to have failed the evaluation. Follow-up education in the form of a hands-on workshop was provided for physicians who worked in medical institutions that failed the QA evaluation. A questionnaire about basic knowledge and experience with US was administered during follow-up education. RESULTS: After the QA evaluation, 542 of 685 hospitals and 1340 of 1985 private clinics passed the test. The evaluation of private clinics and hospitals showed substantial differences in the frequency of adequacy or mean scores between the pass and fail groups for all QA items, even requirements. Among 233 participants in the hands-on workshops, 187 physicians (80.2%) responded to the questionnaire. Results revealed that physicians had deficient knowledge and experience about liver US. CONCLUSIONS: The quality of liver US for hepatocellular carcinoma screening remains suboptimal. Education for physicians who perform liver US examinations is unsatisfactory in Korea. We should make an effort to improve the quality of liver US and teach basic US techniques to physicians.

BACKGROUND AND AIMS: HEV has been associated with a number of neurological syndromes, but causality has not yet been established. AIM: to explore the relationship between HEV and neurological illness by prospective HEV-testing of patients presenting with acute non-traumatic neurological injury. METHODS: 464 consecutive patients presenting to hospital with acute non-traumatic neurological illnesses were tested for HEV by serology and PCR from 4 centres in the UK, France and the Netherlands. RESULTS: 11/464 patients (2.4%) had evidence of current/recent HEV infection. Seven had HEV RNA identified in serum and 4 were diagnosed serologically. Neurological cases in which HEV infection was found included neuralgic amyotrophy (n=3, all PCR positive); cerebral ischemia or infarction (n=4); seizure (n=2); encephalitis (n=1); and an acute combined facial and vestibular neuropathy (n=1). None of these cases were clinically jaundiced and median ALT at presentation was 24 IU/L (range 8-145). Cases of HEV-associated neuralgic amyotrophy were found in each of the participating countries: all were middle-aged males with bilateral involvement of the brachial plexus. CONCLUSIONS: In this cohort of patients with non-traumatic neurological injury, 2.4% had evidence of HEV infection. Symptoms of hepatitis were mild or absent and no patients were jaundiced. The cases of HEV associated neuralgic amyotrophy had similarities with other HEV-associated cases described in a large retrospective study. This observation supports a causal relationship between HEV and neuralgic amyotrophy. To further understand the relevance of HEV infection in patients with acute neurological illnesses, case control studies are warranted. LAY SUMMARY: Hepatitis E virus (HEV), as its name suggests, is a hepatropic virus, i.e. it causes damage to the liver (hepatitis). Our findings show that HEV can also be associated with a range of injury to the nervous system.

BACKGROUND AND AIMS: Acute-on-chronic liver failure (ACLF) is the most life-threatening complication of cirrhosis. Prevalence and outcomes of ACLF have been recently described in hospitalized patients with cirrhosis. However, no data is currently available on the prevalence and the risk factors of ACLF in outpatients with cirrhosis. The aim of this study was to evaluate incidence, predictors and outcomes of ACLF in a large cohort of outpatients with cirrhosis. METHODS: 466 patients with cirrhosis consecutively evaluated in a tertiary hospital outpatient clinic were included and followed up until death and/or liver transplantation for a mean of 45±44 months. Data on development of hepatic and extrahepatic organ failures were collected during this period. ACLF was defined and graded according to the EASL-CLIF Consortium definition. RESULTS: During the follow up, 118 patients (25%) developed ACLF: 57 grade-1, 33 grade-2 and 28 grade-3. The probability of developing ACLF was 14%, 29%, and 41% at one year, five years, and ten years, respectively. In the multivariate analysis, baseline mean arterial pressure (HR=0.96; p=0.012), ascites (HR=2.53; p=0.019), MELD score (HR=1.26; p<0.001) and baseline haemoglobin (HR= 0.07; p=0.012) were found to be independent predictors of the development of ACLF at one year. As expected, ACLF was associated with a poor prognosis, with a 3-month probability of transplant-free survival of 56%. CONCLUSIONS: Outpatients with cirrhosis have a high risk of developing ACLF. The degree of liver failure and circulatory dysfunction are associated with the development of ACLF as well as low values of haemoglobin. These simple variables may help to identify patients with high risk of developing ACLF and to plan a close program of surveillance and prevention in these patients. LAY SUMMARY: There is a need to identify predictors of ACLF in patients with cirrhosis in order to identify patients at high risk of developing ACLF and to plan strategies of prevention. In this study, we identified four simple predictors of ACLF: MELD score, ascites, mean arterial pressure and haemoglobin. These variables may help to identify patient with cirrhosis at high risk of developing ACLF that are candidates for new strategies of surveillance and prevention. Anemia is a potential new target for treating these patients.

BACKGROUND AND AIMS: Effective strategies are needed to address dramatic increases in hepatitis C virus (HCV) infection among people who inject drugs (PWID) in rural settings of the United States (US). We determined the required scale-up of HCV treatment with or without scale-up of HCV prevention interventions to achieve a 90% reduction in HCV chronic prevalence or incidence by 2025 and 2030 in a rural US setting. DESIGN: An ordinary differential equation model of HCV transmission calibrated to HCV epidemiological data obtained primarily from a HIV-outbreak investigation in Indiana. SETTING: Scott County, Indiana (population 24,181), USA, a rural setting with negligible baseline interventions, increasing HCV epidemic since 2010, and 55.3% chronic HCV prevalence amongst PWID in 2015 PARTICIPANTS: PWID MEASUREMENTS: Required annual HCV treatments per 1000 PWID (and initial annual percentage of infections treated) to achieve a 90% reduction in HCV chronic prevalence or incidence by 2025/30, either with or without scaling-up syringe service programs (SSPs) and medication-assisted treatment (MAT) to 50% coverage. Sensitivity analyses considered whether this impact could be achieved without retreatment of reinfections, and whether greater intervention scale-up was required due to the increasing epidemic in this setting. FINDINGS: To achieve a 90% reduction in incidence and prevalence by 2030, without MAT and SSP scale-up, 159 per 1000 PWID (initially 25% of infected PWID) need to be HCV-treated annually. However, with MAT and SSP scaled-up, treatment rates are halved (89 per 1000 annually or 15%). To reach the same target by 2025 with MAT and SSP scaled-up, 121 per 1000 PWID (20%) need treatment annually. These treatment requirements are 3-fold higher than if the epidemic was stable, and the impact targets are unattainable without retreatment. CONCLUSIONS: Combined scale-up of hepatitis C virus (HCV) treatment and prevention interventions is needed to decrease the increasing burden of HCV incidence and prevalence in rural Indiana, USA, by 90% by 2025/30.

BACKGROUND: Numerous economic models have been published evaluating treatment of chronic hepatitis C virus (HCV) infection, but none provide a comprehensive comparison among new antiviral agents. OBJECTIVE: Evaluate the cost-effectiveness of all recommended therapies for treatment of genotypes 1 and 4 chronic HCV. METHODS: Using data from clinical trials, observational analyses, and drug pricing databases, Markov decision models were developed for HCV genotypes 1 and 4 to compare all recommended drugs from the perspective of the third-party payer over a 5-, 10-, and 50-year time horizon. A probabilistic sensitivity analysis (PSA) was conducted by assigning distributions for clinical cure, age entering the model, costs for each health state, and quality-adjusted life years (QALYs) for each health state in a Monte Carlo simulation of 10 000 repetitions of the model. RESULTS: In the lifetime model for genotype 1, effects ranged from 18.08 to 18.40 QALYs and total costs ranged from $88 107 to $184 636. The lifetime model of genotype 4 treatments had a range of effects from 18.23 to 18.43 QALYs and total costs ranging from $87 063 to $127 637. Grazoprevir/elbasvir was the optimal strategy followed by velpatasvir/sofosbuvir as the second-best strategy in most simulations for both genotypes 1 and 4, with drug costs and efficacy of grazoprevir/elbasvir as the primary model drivers. CONCLUSIONS: Grazoprevir/elbasvir was cost-effective compared with all strategies for genotypes 1 and 4. Effects for all strategies were similar with cost of drug in the initial year driving the results.

Cell growth and proliferation are tightly coupled to metabolism, and dissecting the signaling molecules which link these processes is an important step towards understanding development, regeneration and cancer. The transcriptional regulator Yes-associated protein 1 (YAP) is a key regulator of liver size, development and function. We now show that YAP can also suppress gluconeogenic gene expression. Yap deletion in primary hepatocytes potentiates the gluconeogenic gene response to glucagon and dexamethasone, whereas constitutively active YAP suppresses it. The effects of YAP are mediated by the transcriptional coactivator peroxisome proliferator-activated receptor gamma coactivator 1 (PGC1α). YAP inhibits the ability of PGC1α to bind to and activate transcription from the promoters of its gluconeogenic targets and the effects of YAP are blunted upon knockdown of PGC1α. In vivo, constitutively active YAP lowers plasma glucose levels and increases liver size. YAP therefore appears to reprogram cellular metabolism, diverting substrates away from the energy consuming process of gluconeogenesis, and towards the anabolic process of growth.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide. The initiation of protein translation is an important rate-limiting step in eukaryotes and is crucial in many viral infections. Eukaryotic translation initiation factors (eIFs) are involved in the initiation step of protein translation and are linked to the phosphatidylinositol-3-kinases PI3K/AKT/mTOR pathway. Therefore we aimed to investigate a potential role of eIFs in HCC. We herein report on the immunohistochemical expression of the various eIF subunits in 235 cases of virus-related human HCC. Additionally, we used immunoblot analysis to investigate the expression of virus-related HCC and non-virus-related HCC in comparison to controls. Mammalian target of rapamycin (or mechanistic target of rapamycin as it is known now (mTOR) and activated mTOR were significantly increased in chronic hepatitis C (HCV)-associated HCC, in HCC without a viral background, in alcoholic liver disease and Wilson disease. pPTEN, phosphatase and tensin homologue (PTEN) and pAKT showed a significant increase in HBV- and HCV-associated HCC, chronic hepatitis B, HCC without a viral background, alcoholic steatohepatitis (ASH) and Wilson disease. Phosphorylated (p)-eIF2α, eIF2α, eiF3B, eIF3D, eIF3J, p-eIF4B, eIF4G and eIF6 were upregulated in HCV-associated HCC. eIF2α, p-eIF4B, eIF5 and various eIF3 subunits were significantly increased in chronic hepatitis B (HBV)-associated HCC. HCC without viral background displayed a significant increase for the eIF subunits p-2α, 3C, 3I, 4E and 4G. We noticed engraved differences in the expression pattern between chronic hepatitis B and C, HBV- and HCV-associated HCC and non-virus-related HCC.

OBJECTIVES: Mortality due to liver disease (of which cirrhosis is the end stage) is increasing more than any other chronic condition in the UK. This study aims to demonstrate that (1) exclusive reliance on mortality rates may not reveal the true burden of liver cirrhosis, and (2) diverse use of diagnostic coding may produce misleading estimates. DESIGN: Observational study. SETTING: The Office for National Statistics death registry was interrogated to investigate liver cirrhosis mortality trends in England and Wales from 1968 to 2011. MAIN OUTCOME: Standardised mortality trends according to three different definitions of liver cirrhosis based on the specificity of diagnostic codes were calculated: 1 (chronic liver diseases), 2 (alcoholic and unspecified cirrhosis only) and 3 (cirrhosis as end-stage liver disease). The mortality trends were compared with incidence rates established in a previous population-based study (based on definition 3), from 1998 to 2009, to investigate discrepancies between these two measures. RESULTS: Over the study period, the overall standardised liver cirrhosis mortality rates were 8.8, 5,1 and 5.4 per 100 000 person-years for definitions 1, 2 and 3, respectively. The mortality rates for definition 3 in 1998 and 2009 were 6.2 and 5.9 per 100 000 person-years, respectively; while the equivalent incidence rates were at least threefold and sixfold higher: 23.4 and 35.9 per 100 000 person-years, respectively. This discrepancy between incidence and mortality rates was also at least threefold in men and women separately and across age groups. CONCLUSION: Mortality rates underestimated the incidence of liver cirrhosis by at least threefold between 1998 and 2009 and varied with differing definitions of disease. Mortality data should not be used exclusively as an indicator for the occurrence of liver cirrhosis in the population. Routinely collected healthcare data are available to measure occurrence of this disease. Careful consideration should be taken when selecting diagnostic codes for cirrhosis.

Autoimmune hepatitis has a variable occurrence, clinical phenotype, and outcome, and the factors contributing to this variability are uncertain. The goals of this review are to examine the global disparities in the occurrence and outcome of autoimmune hepatitis, suggest bases for these disparities, and encourage investigations that extend beyond single-center experiences. Disparities in the incidence and prevalence of autoimmune hepatitis in different age groups, genders, ethnicities, and geographical regions suggest that factors other than genetic predisposition are involved. Age- and gender-related antigen exposures from the external (infections, toxins, and medications) and internal (intestinal microbiome) environment may affect the incidence of the disease, and the timeliness and nature of treatment may influence its prevalence. The increasing incidence of autoimmune hepatitis in Spain, Denmark, and the Netherlands suggests that a new etiological trigger has been introduced or that the susceptible population has changed. Variations in mortality between Western and Asian-Pacific countries may result from differences in disease detection or management, and variations in gender predilection, peak age of onset, frequency of concurrent immune diseases, and serological profile may reflect gender-biased and age-related antigen exposures and genetic predispositions. Global collaborations, population-based epidemiological studies that identify case clustering, and controlled interview-based surveys are mechanisms by which to understand these disparities and improve management. In conclusion, autoimmune hepatitis has a rising incidence in some countries and variable occurrence, phenotype, and outcome between countries and subgroups within countries. These disparities suggest that unrecognized population-based environmental, infectious, or socioeconomic factors are affecting its character.

BACKGROUND AND AIMS: In Scotland, Hepatitis B virus (HBV) vaccination for all prisoners was introduced in 1999; here, we examine the impact of this programme among people who inject drugs (PWID) in the community. This study aimed to compare rates of HBV vaccine uptake before and after implementation of the prison programme and to estimate the determinants of vaccine uptake, the levels of ever/current HBV infection and the associations between vaccine uptake and ever/current HBV infection. DESIGN: Data collected via serial cross-sectional surveys were used to compare the proportion who reported being vaccinated over time. For the 2013-14 survey, rates of ever/current HBV infection were calculated and the associations between vaccine uptake and ever/current HBV infection were examined using logistic regression. SETTING: Services providing injecting equipment and drug treatment, and street sites, in Glasgow (1993-2002) and across Scotland (2008-2014). PARTICIPANTS: More than 10,000 PWID in total were recruited in the surveys. MEASUREMENTS: Participants completed a questionnaire (all years) to ascertain self-reported vaccine uptake and provided a blood spot (in 2013-14), tested for HBV core antibodies (anti-HBc) and surface antigen (HBsAg). FINDINGS: Among recent-onset PWID in Glasgow, vaccine uptake increased from 16-20% in 1993-99 to 52-59% in 2001-2014 (p<0.001). Among all PWID in Scotland, uptake increased further from 71% in 2008-09 to 77% in 2013-14 (p<0.001) and was associated with incarceration (adjusted odds ratio 2·91, 95% CI 2·23-3·79). The prevalence of anti-HBc and HBsAg in Scotland was 2·6% and 0·3%, respectively, among PWID who had commenced injecting in the decade since the programme's introduction. Vaccination was associated with reduced odds of ever (0·60, 0·37-0·97) and current (0·40, 0·16-0·97) HBV infection. CONCLUSIONS: In Scotland, uptake of Hepatitis B virus (HBV) vaccination among people who inject drugs (PWID) in the community has increased since the 1999 introduction of universal prison vaccination, and current levels of HBV infection among PWID are low compared with other European countries.

The Liver Imaging Reporting and Data System (LI-RADS(®)) is an imaging-based diagnostic system applicable in patients at high risk of hepatocellular carcinoma (HCC). In LI-RADS, each liver observation is assigned a category that reflects probability of benignity, HCC, or other malignancy. Familiarity with the LI-RADS diagnostic algorithm is necessary to appropriately implement LI-RADS in clinical practice. This review discusses steps necessary for application of the LI-RADS algorithm and provides examples illustrating each step.
