Abstract
BACKGROUND Alcohol liver disease (ALD) may coexist with hepatitis C (HCV) in many transplant recipients (alcoholic cirrhosis with hepatitis C [AHC]). Our objective was to determine whether there were differences in postliver transplantation outcomes of patients with AHC when compared with those with alcoholic cirrhosis (AC) and/or alcoholic hepatitis (AH). METHODS Using UNOS explant data sets (2016-2020), the survival probabilities of AC, AH, and AHC were compared by Kaplan-Meier survival analysis. Cox proportional-hazard regression analysis was used to determine outcomes after adjusting for disease confounders. The outcomes were also compared with predirect antiviral agent (DAA) period. RESULTS During study period, 8369 biopsy-proven ALD liver transplant recipients were identified. Of those, 647 had AHC (HCV + alcohol), 353 had AH, and 7369 had AC. MELD-Na score (28.7 ± 9.5 versus 23.8 ± 10.7, P < 0.001) and presence of ACLF-3 (19% versus 11%, P < 0.001) were higher in AC + AH as compared with AHC. AHC and AC+AH has similar adjusted mortality at 1-y, but 3-y (hazard ratios, 1.76; 95% confidence intervals, 1.32-2.35; P < 0.0001) and 5-y (hazard ratios, 1.64; 95% confidence intervals, 1.24-2.15; P = 0.0004) mortality rates were higher in AHC. Survival improved in the DAA era (2016-2020) compared with 2009 to 2013 in AHC, but remained worse in AHC group versus AC and/or AH. Malignancy-related mortality was higher in AHC (15% versus 9.3% in AC) in the DAA era. CONCLUSIONS AHC was associated with lower 3- and 5-y post-LT survival as compared with ALD without HCV and the worse outcomes in AHC group continued in the DAA era.

Andaloro S, Mancuso F, Miele L, Addolorato G, Gasbarrini A, Ponziani FR. Effect of Low-Dose Alcohol Consumption on Chronic Liver Disease. Nutrients 2024; 16:613. [PMID: 38474740 DOI: 10.3390/nu16050613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Revised: 02/16/2024] [Accepted: 02/18/2024] [Indexed: 03/14/2024] Open
Abstract
Although alcohol is one of the most important etiologic agents in the development of chronic liver disease worldwide, also recognized as a promoter of carcinogenesis, several studies have shown a beneficial effect of moderate consumption in terms of reduced cardiovascular morbidity and mortality. Whether this benefit is also present in patients with liver disease due to other causes (viral, metabolic, and others) is still debated. Although there is no clear evidence emerging from guidelines and scientific literature, total abstention from drinking is usually prescribed in clinical practice. In this review, we highlight the results of the most recent evidence on this controversial topic, in order to understand the effect of mild alcohol use in this category of individuals. The quantification of alcohol intake, the composition of the tested populations, and the discrepancy between different works in relation to the outcomes represent important limitations emerging from the scientific literature. In patients with NAFLD, a beneficial effect is demonstrated only in a few works. Even if there is limited evidence in patients affected by chronic viral hepatitis, a clear deleterious effect of drinking in determining disease progression in a dose-dependent manner emerges. Poor data are available about more uncommon pathologies such as hemochromatosis. Overall, based on available data, it is not possible to establish a safe threshold for alcohol intake in patients with liver disease.

Abstract
Alcohol consumption has been linked to numerous negative health outcomes although it has some beneficial effects on moderate dosages, the most severe of which being alcohol-induced hepatitis. The number of people dying from this liver illness has been shown to climb steadily over time, and its prevalence has been increasing. Researchers have found that alcohol consumption primarily affects the brain, leading to a wide range of neurological and psychological diseases. High-alcohol-consumption addicts not only experienced seizures, but also ataxia, aggression, social anxiety, and variceal hemorrhage that ultimately resulted in death, ascites, and schizophrenia. Drugs treating this liver condition are limited and can cause serious side effects like depression. Serine-threonine kinases, cAMP protein kinases, protein kinase C, ERK, RACK 1, Homer 2, and more have all been observed to have their signaling pathways disrupted by alcohol, and alcohol has also been linked to epigenetic changes. In addition, alcohol consumption induces dysbiosis by changing the composition of the microbiome found in the gastrointestinal tract. Although more studies are needed, those that have been done suggest that probiotics aid in keeping the various microbiota concentrations stable. It has been argued that reducing one's alcohol intake may seem less harmful because excessive drinking is a lifestyle disorder.

Abstract
Hepatocellular carcinoma (HCC) is the most common liver cancer and has a propensity to develop arteriovenous fistulas with the surrounding vasculature, making targeted intravascular treatment more difficult. HCC can oftentimes be accompanied by portal hypertension and liver cirrhosis, which can, in turn, cause recanalization of the umbilical vein. In rare circumstances, arteriovenous fistula formation and shunting into the recanalized and enlarged umbilical vein can occur. In the following presented case of HCC, an arteriovenous shunt between the anterior division of the right hepatic artery and a recanalized umbilical vein is demonstrated. Subsequent successful endovascular coil embolization of the fistula was performed to avoid shunting and non-target embolization of the radiation particles in the umbilical vein territory. Post-embolization angiogram with DynaCT and lack of Tc-99m macroaggregated albumin deposition in the umbilical vein distribution confirmed the resolution of the shunt. The patient then received targeted Y-90 transarterial radioembolization locoregional therapy in combination with systemic therapy.

Abstract
Alcohol-related hepatitis (ARH) is a unique type of alcohol-associated liver disease characterized by acute liver inflammation caused by significant alcohol use. It ranges in severity from mild to severe and carries significant morbidity and mortality. The refinement of scoring systems has enhanced prognostication and guidance of clinical decision-making in the treatment of this complex disease. Although treatment focuses on supportive care, steroids have shown benefit in select circumstances. There has been a recent interest in this disease process, as coronavirus disease 2019 pandemic led to substantial rise in cases. Although much is known regarding the pathogenesis, prognosis remains grim due to limited treatment options. This article summarizes the epidemiology, genetics, pathogenesis, diagnosis and treatment of ARH.

Abstract
OBJECTIVE To investigate whether direct-acting antivirals (DAA) for hepatitis C viral infection (HCV): glecaprevir/pibrentasvir (GLE/PIB), ledipasvir/sofosbuvir (LDV/SOF), and sofosbuvir/velpatasvir (SOF/VEL) are associated with reduced alcohol consumption among veterans with alcohol use disorder (AUD) and co-occurring post-traumatic stress disorder (PTSD). METHODS We measured change in Alcohol Use Disorder Identification Test-Consumption Module (AUDIT-C) scores in a retrospective cohort of veterans with PTSD and AUD receiving DAAs for HCV. RESULTS One thousand two hundred and eleven patients were included (GLE/PIB n = 174, LDV/SOF n = 808, SOF/VEL n = 229). Adjusted frequencies of clinically meaningful improvement were 30.5% for GLE/PIB, 45.5% for LDV/SOF, and 40.5% for SOF/VEL. The frequency was lower for GLE/PIB than for LDV/SOF (OR = 0.59; 95% CI [0.40, 0.87]) or SOF/VEL (OR = 0.66; 95% CI [0.42, 1.04]). CONCLUSIONS DAA treatment for HCV was associated with a substantial reduction in alcohol use in patients with AUD and co-occurring PTSD. Further exploration of the role of DAAs in AUD treatment is warranted.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection and excessive alcohol consumption are leading causes of liver disease worldwide. Direct acting antivirals (DAAs) are well-tolerated treatments for HCV infections with high sustained virologic response (SVR) rates. There are limited data assessing the influence of alcohol use on DAA uptake and cure. METHODS We performed a retrospective analysis of patients followed at The Ottawa Hospital Viral Hepatitis Program between January 2014 and May 2020 to investigate the effect of excessive alcohol use history on DAA uptake and SVR rates. Additionally, we evaluated the incidence of concurrent comorbidities and social determinants of health. Predictors of DAA uptake and SVR were assessed by logistic regression. RESULTS Excessive alcohol use history was reported in 46.0% (733) of patients. Excessive alcohol use did not predict DAA uptake (OR 1.06, 95% CI 0.71 to 1.57), while employment (OR 2.10, 95% CI 1.29 to 3.42) and recreational drug use (OR 0.62, 95% CI 0.40 to 0.94) were predictors. Employment predicted SVR (OR 2.38, 95% CI 1.68 to 3.36) in those starting treatment. Excessive alcohol use history did not predict SVR. CONCLUSIONS History of excessive alcohol use does not influence treatment initiation or SVR. Efforts to improve treatment uptake should shift to focus on the roles of determinants of health such as employment and recreational drug use on treatment initiation.

Abstract
Introduction of effective drugs in the treatment of hepatitis C virus (HCV) infection has prompted the World Health Organization to declare a global eradication target by 2030. Propositions have been made to screen the general population and treat all HCV carriers irrespective of the disease status. A year ago the new severe acute respiratory syndrome coronavirus 2 virus appeared causing a worldwide pandemic of coronavirus disease 2019 disease. Huge financial resources were redirected, and the pandemic became the first priority in every country. In this review, we examined the feasibility of the World Health Organization elimination program and the actual natural course of HCV infection. We also identified and analyzed certain comorbidity factors that may aggravate the progress of HCV and some marginalized subpopulations with characteristics favoring HCV dissemination. Alcohol consumption, HIV coinfection and the presence of components of metabolic syndrome including obesity, hyperuricemia and overt diabetes were comorbidities mostly responsible for increased liver-related morbidity and mortality of HCV. We also examined the significance of special subpopulations like people who inject drugs and males having sex with males. Finally, we proposed a different micro-elimination screening and treatment program that can be implemented in all countries irrespective of income. We suggest that screening and treatment of HCV carriers should be limited only in these particular groups.

Abstract
Drinking alcohol, even in moderation, can affect the immune system. Studies have shown disproportionate effects of alcohol on circulating and tissue-resident myeloid cells (granulocytes, monocytes, macrophages, dendritic cells). These cells orchestrate the body's first line of defense against microbial challenges as well as maintain tissue homeostasis and repair. Alcohol's effects on these cells are dependent on exposure pattern, with acute drinking dampening but chronic drinking enhancing production of inflammatory mediators. Although chronic drinking is associated with heightened systemic inflammation, studies on tissue resident macrophage populations in several organs including the spleen, liver, brain, and lung have also shown compromised functional and metabolic capacities of these cells. Many of these effects are thought to be mediated by oxidative stress caused by alcohol and its metabolites which can directly impact the cellular epigenetic landscapes. In addition, since myeloid cells are relatively short-lived in circulation and are under constant repopulation from the bone marrow compartment, alcohol's effects on bone marrow progenitors and hematopoiesis are important for understanding the impact of alcohol systemically on these myeloid populations. Alcohol-induced disruption of progenitor, circulating, and tissue resident myeloid populations contribute to the increased susceptibility of patients with alcohol use disorders to viral and bacterial infections. In this review, we provide an overview of the impact of chronic alcohol consumption on the function of monocytes and macrophages in host defense, tissue repair and inflammation. We then summarize our current understanding of the mechanisms underlying alcohol-induced disruption and examine changes in transcriptome and epigenome of monocytes and mcrophages. Overall, chronic alcohol consumption leads to hyper-inflammation concomitant with decreased microbial and wound healing responses by monocytes/macrophages due to a rewiring of the epigentic and transcriptional landscape. However, in advanced alcoholic liver disease, myeloid cells become immunosuppressed as a response to the surrounding hyper-inflammatory milieu. Therefore, the effect of chronic alcohol on the inflammatory response depends on disease state and the immune cell population.

Abstract
BACKGROUND Alcohol, insulin resistance (IR), and hepatitis C (HCV) are all significant contributors to adverse outcomes of chronic liver disease. Latinos are disproportionately affected by these risk factors. We investigated the relationship between alcohol use and insulin action in a prospective cohort of Latino individuals with and without HCV. METHODS One hundred fifty-three nondiabetic Latino individuals (60 HCV+, 93 HCV-) underwent clinical evaluation and metabolic testing; 56 had repeat testing over a median follow-up of 1.5 years. Peripheral IR and hepatic IR were measured via steady-state plasma glucose (SSPG) and endogenous glucose production during a two-step, 240-min insulin suppression test. Insulin secretion (IS) was measured using the graded glucose infusion test. Alcohol use was categorized as none, moderate (≤1 drink/day for women and ≤2 drinks/day for men), and heavy (>moderate). Multivariable models including HCV status assessed associations of alcohol use with baseline SSPG, hepatic IR and IS, and changes in these parameters over time. RESULTS Overall, the median age was 44 years, 63.4% were male, 66.7% overweight/ obese, and 31.9% had heavy lifetime alcohol use while 60.4% had moderate lifetime alcohol use. SSPG and IS were similar by levels of alcohol use at baseline and alcohol use was not statistically significantly associated with change in these measures over time. However, lifetime daily heavy alcohol use (vs. not heavy, coef 2.4 μU-mg/kg-min-ml, p = 0.04) and HCV status (coef 4.4 μU-mg/kg-min-ml, p = 0.0003) were independently associated with higher baseline hepatic IR, and current heavy alcohol use was associated with greater change in hepatic IR in follow-up (coef 5.8 μU-mg/kg-min-ml, p = 0.03). CONCLUSIONS In this cohort of Latino individuals, lifetime and current heavy alcohol use influenced hepatic IR and its change over time. Strategies to decrease rates of heavy alcohol use or increase abstinence along with lifestyle modification and anti-HCV therapy to reduce metabolic risk are critical to prevent adverse liver and metabolic outcomes in Latino individuals.

Abstract
Patients with alcohol-associated liver disease may develop severe forms of presentation of acute-on-chronic liver failure, with a high risk for short-term mortality. Alcoholic hepatitis should be suspected among patients with alcohol-associated liver disease who present with acute-on-chronic liver failure. In this review, we discuss the need and feasibility of liver biopsy in the diagnosis of alcoholic hepatitis and predicting its prognosis among decompensated patients with alcohol-associated liver disease and acute-on-chronic liver failure.

Abstract
The liver is the main target organ for hepatitis viruses and the vital organ for alcohol metabolism. These two factors of viral hepatitis and alcohol abuse in combination can exert dual harmful actions, leading to enhanced damage to the liver. Epidemiological studies have revealed a higher prevalence of hepatitis C virus (HCV) infection among alcoholics than the general population. The interaction of alcohol with viral hepatitis [e.g., hepatitis B virus (HBV), HCV] and the underlying mechanisms are not fully understood. The effects of alcohol on viral hepatitis include promoted viral replication, weakened immune response, and increased oxidative stress. Clinically, alcohol abuse is correlated with an increased risk of developing end-stage liver cirrhosis and hepatocellular carcinoma in patients with chronic hepatitis B and C, suggesting that the combination of alcohol and HBV/HCV lead to more severe liver damage. The influence of mild to moderate alcohol drinking on the HBV-induced liver fibrosis, cirrhosis, and hepatocellular carcinoma among patients infected with HBV remains unclear. Unlike HBV infected patients, no safe level of alcohol intake has been established for patients with HCV. Even light to moderate alcohol use can exert a synergistic effect with viral hepatitis, leading to the rapid progression of liver disease. Furthermore, interferon-based therapy is less effective in alcohol drinkers than in control patients, even after abstinence from alcohol for a period of time. Therefore, abstaining from alcohol is highly recommended to protect the liver, especially in individuals with HBV/HCV infection, to improve the clinical efficacy of antiviral treatment and prevent the rapid progression of chronic viral hepatitis.

Associations Between Alcohol Use and Liver-Related Outcomes in a Large National Cohort of Patients With Cirrhosis. Hepatol Commun 2021; 5:2080-2095. [PMID: 34601829 PMCID: PMC8631097 DOI: 10.1002/hep4.1776] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 05/10/2021] [Accepted: 06/13/2021] [Indexed: 11/11/2022] Open
Abstract
Alcohol use can cause hepatic necroinflammation and worsening portal hypertension in patients with cirrhosis. We aimed to evaluate the associations between degree of alcohol use and clinical liver‐related outcomes according to etiology of cirrhosis. In this retrospective cohort analysis, 44,349 U.S. veterans with cirrhosis from alcohol‐associated liver disease (ALD), chronic hepatitis C virus (HCV) infection, or nonalcoholic fatty liver disease were identified who completed the Alcohol Use Disorders Identification Test Consumption questionnaire in 2012. Based on this score, level of alcohol use was categorized as none, low level, or unhealthy. Multivariable Cox proportional hazards regression was used to assess for associations between alcohol use and mortality, cirrhosis decompensation (new ascites, encephalopathy, or variceal bleeding), and hepatocellular carcinoma (HCC). At baseline, 36.4% of patients endorsed alcohol use and 17.1% had unhealthy alcohol use. During a mean 4.9 years of follow‐up, 25,806 (57.9%) patients died, 9,409 (21.4%) developed a new decompensation, and 4,733 (11.1%) developed HCC. In patients with ALD‐cirrhosis and HCV‐cirrhosis, unhealthy alcohol use, compared with no alcohol use, was associated with higher risks of mortality (adjusted hazard ratio [aHR] = 1.13, 95% confidence interval [CI] = 1.07‐1.19 and aHR = 1.14, 95% CI = 1.08‐1.20, respectively) and decompensation (aHR = 1.18, 95% CI = 1.07‐1.30 and aHR = 1.08, 95% CI = 1.00‐1.16, respectively). Alcohol use was not associated with HCC, regardless of cirrhosis etiology. Conclusion: Unhealthy alcohol use was common in patients with cirrhosis and was associated with higher risks of mortality and cirrhosis decompensation in patients with HCV‐cirrhosis and ALD‐cirrhosis. Therefore, health care providers should make every effort to help patients achieve abstinence. The lack of association between alcohol use and HCC merits further investigation.

Abstract
BACKGROUND Liver cirrhosis and hepatocellular carcinoma (HCC) are common diseases in developing countries. HCC is a serious consequence of liver cirrhosis. METHODS A total of 1095 decompensated hepatic cirrhotic patients admitted to our hospital were enrolled from September 2014 to August 2019. We described the components of cirrhotic etiology. We evaluated the impact of alcohol consumption on the incidence of HCC in patients with hepatitis B cirrhosis and hepatitis C cirrhosis. RESULTS Among all cirrhotic patients admitted, the constituent ratios of hepatitis B cirrhosis and alcohol cirrhosis were 31.32% and 30.32%, respectively. The HCC incidence was higher in patients with hepatitis cirrhosis than in those with alcohol cirrhosis (24.2% in hepatitis B, 17.5% in hepatitis C and 3.92% in alcohol, P < 0.05). The HCC incidence in patients with concomitant hepatitis B virus (HBV) and alcohol consumption was higher than that in patients with HBV alone (33.70% vs. 20.72%, P < 0.05). CONCLUSION Hepatitis B and alcohol were major etiologies for cirrhotic patients. Alcohol consumption increased the incidence of HCC in patients with hepatitis B cirrhosis but not in patients with hepatitis C cirrhosis.

Abstract
Background/Aims Multiple meta-analyses and observational studies have reported that alcohol is a risk factor for liver cancer. However, whether there is a safe level of alcohol consumption remains unclear. We performed a systematic review and meta-analysis of the correlation between low-level alcohol consumption and the risk of liver cancer. Methods Nested case-control studies and cohort studies involving the general population published prior to July 2019 were searched. In total, 28 publications (31 cohorts) with 4,899 incident cases and 10,859 liver cancer-related deaths were included. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Results Compared with those with low levels of alcohol consumption, moderate and heavy drinkers (≥1 drink/day for females and ≥2 drinks/day for males) had pooled ORs of 1.418 (95% CI, 1.192 to 1.687; p<0.001) for liver cancer incidence and 1.167 (95% CI, 1.056 to 1.290; p=0.003) for liver cancer mortality. The pooled OR for liver disease-related mortality for those with more than low levels of alcohol consumption was 3.220 (95% CI, 2.116 to 4.898; p<0.001) and that for all-cause mortality was 1.166 (95% CI, 1.065 to 1.278; p=0.001). The sensitivity analysis showed that none of the studies had a strong effect on the pooled OR. The Egger test, Begg rank correlation test, and the funnel plot showed no overt indication of publication bias. Conclusions Continuous consumption of more than a low-level of alcohol (≥1 drink/day for females and ≥2 drinks/day for males) is related to a higher risk of liver cancer.

Abstract
Alcohol-associated hepatitis (AH) is a unique clinical syndrome in patients with excessive and prolonged alcohol consumption, and negatively impacts the patient outcomes. Among patients with asymptomatic alcohol-associated liver disease with elevated liver enzymes and/or steatosis, liver biopsy is required to diagnose AH. Noninvasive assessment should be performed in these patients to determine risk of advanced fibrosis. In symptomatic patients with jaundice, liver biopsy is required when the clinical diagnosis is uncertain. Liver biopsy is not recommended to determine prognosis of patients with AH. Noninvasive biomarkers are emerging for diagnosis of and determining prognosis of patients with AH.

Abstract
Chronic and excessive alcohol abuse cause direct and indirect detrimental effects on a wide range of body organs and systems and accounts for ~4% of deaths worldwide. Many factors influence the harmful effects of alcohol. This concise review presents newer insights into the role of select second hits in influencing the progression of alcohol-induced organ damage by synergistically acting to generate a more dramatic downstream biological defect. This review specifically addresses on how a lifestyle factor of high fat intake exacerbates alcoholic liver injury and its progression. This review also provides the mechanistic insights into how increasing matrix stiffness during liver injury promotes alcohol-induced fibrogenesis. It also discusses how hepatotropic viral (HCV, HBV) infections as well as HIV (which is traditionally not known to be hepatotropic), are potentiated by alcohol exposure to promote hepatotoxicity and fibrosis progression. Finally, this review highlights the impact of reactive aldehydes generated during alcohol and cigarette smoke coexposure impair innate antimicrobial defense and increased susceptibility to infections. This review was inspired by the symposium held at the 17th Congress of the European Society for Biomedical research on Alcoholism in Lille, France entitled 'Second hits in alcohol-related organ damage'.

Abstract
Hepatitis C virus (HCV) infection is the major risk factor for liver cirrhosis and hepatocellular carcinoma (HCC). The mechanisms of HCC initiation, growth, and metastasis appear to be highly complex due to the decade-long interactions between the virus, immune system, and overlapping bystander effects of host metabolic liver disease. The lack of a readily accessible animal model system for HCV is a significant obstacle to understand the mechanisms of viral carcinogenesis. Traditionally, the primary prevention strategy of HCC has been to eliminate infection by antiviral therapy. The success of virus elimination by antiviral treatment is determined by the SVR when the HCV is no longer detectable in serum. Interferon-alpha (IFN-α) and its analogs, pegylated IFN-α (PEG-IFN-α) alone with ribavirin (RBV), have been the primary antiviral treatment of HCV for many years with a low cure rate. The cloning and sequencing of HCV have allowed the development of cell culture models, which accelerated antiviral drug discovery. It resulted in the selection of highly effective direct-acting antiviral (DAA)-based combination therapy that now offers incredible success in curing HCV infection in more than 95% of all patients, including those with cirrhosis. However, several emerging recent publications claim that patients who have liver cirrhosis at the time of DAAs treatment face the risk of HCC occurrence and recurrence after viral cure. This remains a substantial challenge while addressing the long-term benefit of antiviral medicine. The host-related mechanisms that drive the risk of HCC in the absence of the virus are unknown. This review describes the multifaceted mechanisms that create a tumorigenic environment during chronic HCV infection. In addition to the potential oncogenic programming that drives HCC after viral clearance by DAAs, the current status of a biomarker development for early prediction of cirrhosis regression and HCC detection post viral treatment is discussed. Since DAAs treatment does not provide full protection against reinfection or viral transmission to other individuals, the recent studies for a vaccine development are also reviewed.

Abstract
BACKGROUND AND AIMS Although people who inject drugs (PWID) are the core at-risk population in the hepatitis C virus (HCV) epidemic in industrialized countries, few initiate treatment. Alcohol use disorder (AUD), common within this population, has been identified as a barrier to HCV treatment uptake in the general population. We investigated whether the arrival of new and well-tolerated HCV treatments (direct-acting antivirals: DAA) has improved HCV treatment uptake in French PWID compared with former treatments (pegylated interferon-based treatments: Peg-IFN). DESIGN Using discrete-time Cox proportional hazards models based on exhaustive care delivery data, we tested for associations between AUD (defined by AUD-related long-term illness status, diagnosis coding during hospitalization and/or AUD pharmacological treatment) and first HCV treatment delivery, after adjusting for gender, age, complementary universal health cover, liver disease severity and type of opioid agonist therapy (OAT) received. Separate analyses were performed for 2012-13 (Peg-IFN era) and 2014-16 (DAA era). SETTING France. PARTICIPANTS All French people chronically HCV-infected who received OAT at least once during 2012-16 and were covered by the national health insurance (n = 24 831). MEASUREMENTS Incidence rate of HCV treatment uptake, hazard ratios associated with AUD and other covariates. FINDINGS Incidence rate (IR) of HCV treatment uptake per 100 person-years was 6.56, confidence interval (CI) = 6.30-6.84; and IR = 5.70, 95% CI = 5.51-5.89 for Peg-IFN-based treatment (2012-13) and DAA (2014-16), respectively. After multiple adjustment, people with AUD not receiving related medication had 30 and 14% lower Peg-IFN-based treatment and DAA uptake, respectively, than those without AUD [hazard ratio (HR) = 0.70, 95% CI = 0.62-0.80 and HR = 0.86, 95% CI = 0.78-0.94]. No difference was observed between those treated for AUD and those without AUD. CONCLUSIONS Despite the benefits of direct-acting antiviral treatment, untreated alcohol use disorder appears to remain a major barrier to hepatitis C virus treatment access for people who inject drugs in France.

Abstract
INTRODUCTION AND OBJECTIVES The prevalence of alcohol, tobacco, and coffee use and association with liver health among North Americans with Chronic Hepatitis B (CHB) infection has not been well described. MATERIALS AND METHODS The Hepatitis B Research Network includes an observational study of untreated CHB adults enrolled at 21 sites in the United States and Canada. Alcohol use was categorized as none, moderate, and at-risk based on the definition from the National Institute on Alcohol Abuse and Alcoholism; tobacco use as never, current and former; coffee use as none, 1-2 cups/day, and ≥3 cups/day. Linear regression and linear mixed models were used to associate lifestyle behaviors with ALT and FIB-4 values. RESULTS 1330 participants met eligibility: 53% males, 71% Asian and the median age was 42 years (IQR: 34-52). Median ALT was 33U/L (IQR: 22-50), 37% had HBV DNA <103IU/mL, 71% were HBeAg negative, and 65% had a FIB-4 <1.45. At baseline, 8% of participants were at-risk alcohol drinkers, 11% were current smokers and 92% drank <3 cups of coffee/day. Current tobacco and 'at-risk' alcohol use, were significantly associated with elevated ALT levels in univariable analyses, however, these associations were not statistically significant when controlling for sociodemographic and HBV characteristics. CONCLUSIONS In this large diverse cohort of untreated CHB participants, at-risk alcohol use, current tobacco use and limited coffee consumption did not have an association with high ALT and FIB-4 values. In contrast, significant associations were found between the frequency of these lifestyle behaviors and sociodemographic factors.

Abstract
IMPACT STATEMENT There is a rapidly occurring, dynamic change, in the causes of morbidity and mortality in different populations across the globe. More people today are being diagnosed and treated for chronic diseases such as cancer, cardiovascular disease, and diabetes than ever before. Environmental exposures across the lifespan have a profound impact on the outcomes of these chronic diseases. Further, there are more people living today who have survived their therapy from these diagnoses and who are now differentially susceptible to environmental exposures. Collectively, this poses both the challenge and opportunity to the experimental biology and medicine community to build new models that reflect this changing human situation. The extraordinary advances in our understanding of the biology of disease provide extraordinary insights for both therapeutic and prevention strategies. Multidisciplinary teams including biological, physical, engineering and social and behavioral scientists will be needed to address this problem over the next several decades.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is an increasingly dominant cause of liver disease worldwide. The progressive subtype, nonalcoholic steatohepatitis, is a leading indication for liver transplantation and a noteworthy cause of hepatocellular carcinoma. The overall prevalence of NAFLD is on the rise, and even more concerning data modeling predicts that an increasing percentage of those with NAFLD will develop advanced disease. This increased volume of patients with advanced liver disease will impose a significant health care burden in terms of resources and cost. Thus, the identification of patients with established fibrosis or at high risk of developing advanced liver disease is critical to effectively intervene and prevent overall and liver-related morbidity and mortality. Herein, we provide a framework to consider for the identification of patients with NAFLD at high risk of nonalcoholic steatohepatitis with advanced fibrosis and provide a critical assessment of currently accessible diagnostic and treatment modalities.

Abstract
The purpose of this study was to compare quality of life, functioning, and coping among hepatitis C virus (HCV) patients who continued versus ceased alcohol use in the past year. HCV patients (n = 291) were recruited from three liver and infectious disease clinics. Student's t test was used to compare HCV patients who were former and active users of alcohol. The majority of HCV patients were male, African American, and without a high school degree. Compared to former users of alcohol, active users of alcohol self-reported lower ratings on home life, personal leisure, and overall quality of life. In the area of functioning, active users of alcohol self-reported lower ratings on home life, close relationships, sex life, and overall functioning. The two groups did not differ on coping. Most HCV clinicians advise HCV patients to avoid alcohol completely because of its adverse biological effects on the liver. Despite this important advice by their HCV clinicians, most HCV patients continue to use alcohol. HCV clinicians can additionally consider advising these patients that continued alcohol use is associated with lower quality of life and functioning as further evidence to convince these patients to avoid alcohol or to participate in alcohol cessation treatment.

Abstract
Chronic hepatitis C virus (HCV) and alcohol are common causes of chronic liver diseases and both are recognized as major causes of liver disease worldwide. Each poses a major public and economic burden to society, and when the two co-exist they appear to have a synergistic effect in the progression of chronic liver disease. In this research, we developed a SIRS model of transmission of the hepatitis C virus (HCV) under effect of liquoring in six compartments: Susceptible, Low liquoring, High liquoring, Acute, Chronic and Recovered Individuals. The system of non-linear ordinary differential equations is formulated. Basic reproduction number R0 is computed using the next generation matrix approach. The stability of the model is worked out at the equilibrium point. Model analysis shows that the disease-free equilibrium point is both locally and globally asymptotically stable. Sensitivity analysis with respect to key parameters of R0 indicates that control strategies should target reduction of the amount of alcohol use amongst people with HCV as it prevents or delays HCV disease progression. The control in our model is in terms of rehabilitation center which helps people to divert from high liquoring to low liquoring. Numerical simulation has been carried out to show the impact of control on different compartment. This research shows the positive impact of rehabilitation on liquoring habits and subsequently on HCV transmission.

Abstract
BACKGROUND & AIMS Familial aggregation of metabolic traits in NAFLD is well documented. However, relevance of these traits in alcoholic cirrhosis is not well studied. We aimed to explore the association of family history of metabolic traits with age at diagnosis, severity and complications of alcoholic cirrhosis. METHODS In a cross-sectional study, all consecutive patients with alcoholic cirrhosis presenting to our tertiary care centre were included. Family and personal history, demographic characteristics, medical history, anthropometric measurements and laboratory data were recorded. The amount and duration of alcohol consumption were also carefully recorded. RESULTS Out of 1084 alcoholic cirrhotics (age 48.5 ± 10.1 years, all males), family history for metabolic traits was documented in 688 (63.5%) patients. These patients had younger age at diagnosis, increased incidence of jaundice, ascites, variceal bleed and hepatic encephalopathy with consequently higher MELD and CTP score. These patients developed cirrhosis despite shorter median duration (13 years, IQR 7-20 vs 21, IQR 18-25) and lesser amount of alcohol consumption (74 g/d, IQR 24-96 vs 144, IQR 100-148). Patients with both family and personal history of metabolic traits had a higher risk by 3.3 times (95% CI 2.2-4.8) of an early age at diagnosis, 13.2 times (95% CI 8.7-20.1) of progression to cirrhosis with lesser amount of alcohol consumption and 4.6 times (95% CI 3.1-6.9) with lesser duration of alcohol consumption. CONCLUSIONS Positive family and personal history of metabolic traits predispose to alcoholic cirrhosis with an earlier age at onset and more severity despite lesser exposure to alcohol.

Abstract
Aims To provide an overview of published literature on the interaction of alcohol and hepatitis C virus (HCV) in the accelerated progression of liver disease to cirrhosis as relates to decision-making for the management of the liver transplant candidate and recipient. Methods General PubMed search was employed along with expert input to identify the relevant articles on the topic. The authors also utilized both backward and forward citation review of the relevant articles and reviews to identify articles on identified topic. Results In HCV cases, heavy alcohol use has been associated with more severe fibrosis, but even low rates of use may have deleterious effects. Patients with chronic hepatitis C and alcoholic liver disease can be cured of the HCV-theoretically positively impacting outcome and reducing the need for liver transplantation. Current antiviral therapy achieves virologic cure or sustained viral response (SVR) in over 90% of cases. Antiviral therapy is so effective that most liver transplant candidates or recipients can be cured of HCV either prior to or after transplantation. However, despite successful antiviral therapy, liver disease may progress after SVR due to the effects of ongoing alcohol use. Conclusion Antiviral therapy in patients with HCV plus alcohol should improve pre- and post-transplant outcomes, but providers must remain firm in limiting use of alcohol to avoid progression of liver disease post HCV cure. Short Summary Abusive alcohol use and chronic hepatitis C virus (HCV) commonly co-exist and both need to be addressed in liver disease. With high rates of HCV cure with new therapies, attention needs to turn toward ongoing abusive alcohol patterns that may determinately impact liver health both before and after liver transplant.

Abstract
Hepatocellular carcinoma (HCC) is a leading cause of liver-related death worldwide. Hepatitis C virus (HCV) infection is a major cause of advanced hepatic fibrosis and cirrhosis, with significantly increased risk for development of HCC. The morbidity and mortality of HCV-related HCC remains high, as rates of HCV cirrhosis continue to increase. The long-term goal of antiviral therapy for chronic HCV is to reduce complications from cirrhosis, including HCC. The advent of new direct-acting antivirals with high rates of virological clearance has revolutionized cure of HCV infection. While the development of HCC in HCV patients who achieve disease sustained virologic response is reduced, these patients remain at risk for HCC, particularly those patients with advanced fibrosis and cirrhosis. This review outlines the epidemiology of HCC in chronic HCV, various mechanisms, risk factors and pathophysiology that contribute to this disease process, screening recommendations, and the available data on the impact of new direct-acting antiviral treatment on the development on HCC.

Abstract
BACKGROUND AND AIMS Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and its incidence has increased during the past decade. While hepatitis B and C virus infections and alcohol were established risk factors, the impact of smoking on the incidence and mortality of HCC was needed to be confirmed. METHODS We reviewed cohort and case-control studies evaluating the association between cigarette smoking and incidence and mortality of HCC from MEDLINE and Google Scholar. We also checked reference lists of original studies and review articles manually for cross-references up to February 2016. We extracted the relevant information on participant characteristics and study outcomes, as well as information on the methodology of the studies. We also assessed the quality of the included trials using critical appraisal skills program checklists. Meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 81 studies were included in the systematic review. Pooled OR for HCC development with current smokers was 1.55 (95% CI: 1.46 to 1.65; P < 0.00001). Pooled OR for HCC development with former smokers was 1.39 (95% CI: 1.26 to 1.52; P < 0.00001) and pooled OR for HCC development with heavy smokers was 1.90 (95% CI: 1.68 to 2.14; P < 0.00001). Pooled OR for the mortality of current smokers with HCC was 1.29 (95% CI: 1.23 to 1.34; P < 0.00001); and for former smokers with HCC, it was 1.20 (95% CI: 1.00 to 1.42; P = 0.04). CONCLUSIONS Cigarette smoking increases the incidence and mortality of HCC. Further studies are needed to evaluate possible impact of quitting smoking on decreasing this risk.

Abstract
BACKGROUND AND AIMS The risk of hepatocellular cancer (HCC) after sustained virological response (SVR) with direct-acting antivirals (DAA) is unclear. Our aim was to examine the risk and determinants of HCC in patients cured with DAA. METHODS We conducted a retrospective cohort study of hepatitis C virus patients who were treated with DAA in any of the 129 Veterans Health Administration hospitals between January 1, 2015 and December 31, 2015. We calculated the annual incidence rates of HCC by SVR. We used Cox regression models to compare the risk of HCC in patients with vs those without SVR and to identify factors associated with incident HCC among patients with SVR. We reviewed a sample of HCC patients for tumor size and stage at diagnosis. RESULTS Among 22,500 patients treated with DAA (19,518 with SVR; 2982 without SVR), the mean (standard deviation) age was 61.6 (6.1) years, and 39.0% had cirrhosis. There were 271 new cases of HCC, including 183 in patients with SVR. Compared with patients without SVR, those with SVR had a significantly reduced risk of HCC (0.90 vs 3.45 HCC/100 person-years; adjusted hazard ratio, 0.28, 95% CI=0.22-0.36). Patients with cirrhosis had the highest annual incidence of HCC after SVR (1.82 vs 0.34/100 person-years in patients without cirrhosis; adjusted hazard ratio, 4.73. 95% CI, 3.34-6.68). Most (>44.8%) HCC were classified as stage I. Maximum size of the largest lesion was ≤5 cm in over 75% of cases. CONCLUSIONS Among patients treated with DAA, SVR was associated with a considerable reduction in the risk of HCC. We did not find any evidence to suggest that DAAs promote HCC. However, in patients with SVR, the absolute risk of HCC remained high in patients with established cirrhosis. These patients should be considered for ongoing HCC surveillance.

Abstract
Background & objectives: Standard of care for chronic hepatitis C (CHC) in India is peginterferon and ribavirin (RBV). The response to treatment in real life stetting is unclear. The objectives of this study were to evaluate the demographic profile and assess the virological response and predictors of response in CHC patients. Methods: Consecutive patients with CHC were included in this study. Detailed clinical history, risk factors, and predictive factors of response were noted. Patients were treated with peginterferon α2b (1.5 µg/kg/wk) and RBV (12 mg/kg/day) for 6 to 18 months based on response. Results: A total of 211 patients were included in the analysis, mean age 40.6±12.3 yr, 144 (68%) were males and 71 (34%) had compensated cirrhosis. Commonest risk factor for acquiring CHC was previous transfusion and surgery (51%). Genotype 3 (72%) was most common followed by genotype 1 (23%). Overall sustained virologic response (SVR) was 64 per cent [95% CI 57.1%-70.4%]. The SVR was 66.5 per cent [95% CI 58.34-73.89%] for genotype 3 and 61.2 per cent [95% CI 46.23 to 74.80%] for genotype 1. Non-cirrhotics had better SVR rates compared to cirrhotics (76 vs 41%, P<0.001). On multivariate analysis, BMI ≥23 kg/m2, HOMA-IR ≥2, compliance (≤80%), and fibrosis >2 were predictors of low SVR. Interpretation & conclusions: Genotype 3 was the commonest HCV genotype. The commonest source of infection was previous transfusion and surgery. SVR rates for genotypes 3 were better than genotype 1 patients. Predictors of non-response were high BMI, insulin resistance, significant fibrosis and inadequate compliance.

Abstract
Alcohol is a leading cause of liver disease worldwide. Although alcohol abstinence is the crucial therapeutic goal for patients with alcoholic liver disease, these patients have less access to psychosocial, behavioral, and/or pharmacologic treatments for alcohol use disorder. Psychosocial and behavioral therapies include 12-step facilitation, brief interventions, cognitive behavioral therapy, and motivational enhancement therapy. In addition to medications approved by the US Food and Drug Administration for alcohol use disorder (disulfiram, naltrexone, and acamprosate), recent efforts to identify potential new treatments have yielded promising candidate pharmacotherapies. Finally, more efforts are needed to integrate treatments across disciplines toward patient-centered approaches in the management of patients with alcohol use disorder and alcoholic liver disease.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is a leading cause of cancer-related death worldwide. In the United States, HCC is the ninth leading cause of cancer deaths. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Hepatitis B and C are independent risk factors for the development of cirrhosis. Alcohol consumption remains an important additional risk factor in the United States as alcohol abuse is five times higher than hepatitis C. Diagnosis is confirmed without pathologic confirmation. Screening includes both radiologic tests, such as ultrasound, computerized tomography, and magnetic resonance imaging, and serological markers such as α-fetoprotein at 6-month intervals. Multiple treatment modalities exist; however, only orthotopic liver transplantation (OLT) or surgical resection is curative. OLT is available for patients who meet or are downstaged into the Milan or University of San Francisco criteria. Additional treatment modalities include transarterial chemoembolization, radiofrequency ablation, microwave ablation, percutaneous ethanol injection, cryoablation, radiation therapy, systemic chemotherapy, and molecularly targeted therapies. Selection of a treatment modality is based on tumor size, location, extrahepatic spread, and underlying liver function. HCC is an aggressive cancer that occurs in the setting of cirrhosis and commonly presents in advanced stages. HCC can be prevented if there are appropriate measures taken, including hepatitis B virus vaccination, universal screening of blood products, use of safe injection practices, treatment and education of alcoholics and intravenous drug users, and initiation of antiviral therapy. Continued improvement in both surgical and nonsurgical approaches has demonstrated significant benefits in overall survival. While OLT remains the only curative surgical procedure, the shortage of available organs precludes this therapy for many patients with HCC.

Burman BE, Bacchetti P, Khalili M. Moderate Alcohol Use and Insulin Action in Chronic Hepatitis C Infection. Dig Dis Sci 2016; 61:2417-2425. [PMID: 27007134 PMCID: PMC4945365 DOI: 10.1007/s10620-016-4119-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2015] [Accepted: 03/06/2016] [Indexed: 01/06/2023]
Abstract
BACKGROUND AND AIM Chronic hepatitis C (HCV) is associated with metabolic abnormalities including insulin resistance (IR) and diabetes. While moderate alcohol consumption is known to have beneficial metabolic effects in the general population, such potential effects in HCV are unknown. We aimed to assess the association between graded alcohol intake and IR, insulin secretion, and metabolic syndrome in HCV. METHODS Ninety-five non-diabetic HCV-infected patients underwent detailed metabolic testing. IR was directly measured via steady-state plasma glucose (SSPG) during a 240-min insulin suppression test. Total insulin secretion and insulinogenic index were determined by 75-g oral glucose tolerance test. Genotyping of CYP2E1 was performed to detect genetic polymorphisms influencing alcohol metabolism. RESULTS In this cohort, 61 % were abstinent from alcohol for the past 12 months, while 22 % were moderate, and 17 % heavy drinkers. Obesity and nonwhite ethnicity were the strongest predictors of IR. Moderate alcohol intake (vs none) was significantly associated with lower SSPG only among those with normal BMI (coef -72.9, 95 % CI -128.1 to -17.6, p = 0.01). Alcohol use was not associated with insulin secretion parameters when controlling for IR and other factors. Heavy alcohol intake (OR 3.2, 95 % CI 0.86-12.3) and nonwhite ethnicity (OR 7.1, 95 % CI 1.5-33.3) were associated with metabolic syndrome. Among nonwhites, the odds of metabolic syndrome were fivefold higher for heavy drinkers. CONCLUSIONS Moderate alcohol intake is associated with improved insulin sensitivity in HCV, although this benefit was limited to normal-weight individuals. The potential benefit of moderate alcohol on IR and its metabolic consequences in HCV warrants further longitudinal investigation.

Abstract
BACKGROUND Frequency of liver transplantation (LT) is increasing in nonalcoholic steatohepatitis (NASH) with good post-transplant outcomes. Similar data on simultaneous liver kidney (SLK) transplants are limited. METHODS United Network for Organ Sharing database (2002-2011) queried for deceased donor first LT for primary biliary cirrhosis, primary sclerosing cholangitis, or alcoholic cirrhosis (group I), NASH, and cryptogenic cirrhosis with body mass index greater than 30 (group II), and hepatitis C virus with and without alcohol, hepatitis B virus, and hepatocellular carcinoma (group III). RESULTS Of 38 533 LT (9495, 3665, and 25 383 in groups I-III, respectively), about 5.6% (N = 2162) received SLK with 584 (6.2%), 320 (8.7%), and 1258 (5%) in groups I-III, respectively. The SLK performed for group II increased from 6.3% in 2002 to 2003 to 19.2% in 2010 to 2011. Similar trends remained unchanged in group I (26.1 to 26.6%) and decreased in group III (67.6 to 54.5%). Five-year outcomes were similar comparing group II versus group I for liver graft (78 vs 74%, P = 0.14) and patient survival (81 vs 76%, P = 0.07). In contrast, kidney graft outcome was worse for group II (70 vs 79%, P = 0.002). Risk of kidney graft loss was over 1.5-fold higher among group II SLK recipients compared to group I after controlling for recipient characteristics. Estimated glomerular filtration rate remained lower in group II compared with group I at various time points after SLK transplantation. CONCLUSIONS The NASH is the most rapidly growing indication for SLK transplantation with poor renal outcomes. Studies are needed to examine mechanisms of these findings and develop strategies to improve renal outcomes in SLK recipients for NASH.

Alcohol intake alters immune responses and promotes CNS viral persistence in mice. Behav Brain Res 2016; 312:1-8.

Abstract
Chronic hepatitis C virus (HCV) infection leads to progressive liver disease and is associated with a variety of extrahepatic effects, including central nervous system (CNS) damage and neuropsychiatric impairments. Alcohol abuse can exacerbate these adverse effects on brain and behavior, but the molecular mechanisms are not well understood. This study investigated the role of alcohol in regulating viral persistence and CNS immunopathology in mice infected with lymphocytic choriomeningitis virus (LCMV), a model for HCV infections in humans. Female and male BALB/c mice (n=94) were exposed to alcohol (ethanol; EtOH) and water (or water only) using a two-bottle choice paradigm, followed one week later by infection with either LCMV clone 13 (causes chronic infection similar to chronic HCV), LCMV Armstrong (causes acute infection), or vehicle. Mice were monitored for 60days post-infection and continued to receive 24-h access to EtOH and water. Animals infected with LCMV clone 13 drank more EtOH, as compared to those with an acute or no viral infection. Six weeks after infection with LCMV clone 13, mice with EtOH exposure evidenced higher serum viral titers, as compared to mice without EtOH exposure. EtOH intake was also associated with reductions in virus-specific CD8(+) T cell frequencies (particularly CD11a(hi) subsets) and evidence of persistent CNS viremia in chronically infected mice. These findings support the hypothesis that EtOH use and chronic viral infection can result in combined toxic effects accelerating CNS damage and neuropsychiatric dysfunction and suggest that examining the role of EtOH in regulating viral persistence and CNS immunopathology in mice infected with LCMV can lead to a more comprehensive understanding of comorbid alcohol use disorder and chronic viral infection.

Abstract
BACKGROUND Alcoholic cirrhosis (AC) is a common cause of death among individuals abusing alcohol. In the last resort, liver transplantation (LT) is considered the only solution to save the patient's life, generating socioeconomic and public health problems. Clinical and sociodemographic characteristics, rejection frequency, and short- and long-term graft survival are not well known in end-term AC patients undergoing LT. The aim was to determine the sociodemographic and clinical characteristics, their incidence in LT, main pre- and posttransplant complications, and short- and long-term post-transplant graft survival in AC patients in southeastern Spain. METHODS The medical records of 1,026 patients who underwent LT over the last 23 years were retrospectively reviewed, and demographic data and posttransplant survivals were analyzed and compared. Biochemical characteristics, major pre- and posttransplant complications and short- and long-term survivals were analyzed in a total of 398 male patients with AC undergoing LT. RESULTS AC and viral cirrhosis are the main indications for LT in our study. Mostly represented in our study are AC men without associated viral infections with a mean age of 53.06 years. Main pretransplant complications in AC patients are ascites (78.3%) and encephalopathy (43.5%), while acute graft rejection is the most common liver posttransplant complication (26.6%), nevertheless with low graft loss frequency (1.1%). AC and autoimmune cirrhosis show the best posttransplant survival in both the short and long term. Patients with AC included on the waiting list for LT were Child-Pugh class B (52.1%) and Model for End-Stage Liver Disease score of 10 to 19 (71.2%). The highest percentage of AC patient survival was observed at 1 year posttransplant (81.2%) and progressively decreased over time up to 10 years posttransplant (69.6%). Pretransplant complications such as ascites and encephalopathy did not have an influence on the percentage of posttransplant survivals, although better survival rates were observed in nonviral AC patients. CONCLUSIONS AC without viral infections is the main indication for LT in southeastern Spain although its frequency has decreased in last decade. AC is a good indication for LT for its high survival rate and few posttransplant complications. Despite having a high percentage of pretransplant complications (ascites and encephalopathy) but does not appear to influence survivals being observed posttransplant survival rates above those expected. Conversely, viral infections in the patient with AC decrease patient survivals. The main future goals are design new strategies to detect, treat, and reduce AC frequency in our population and know alcoholic recidivism rate posttransplant in our population.

Abstract
In viral proteins, labile Zn-sites, where Zn(2+) is crucial for maintaining the native protein structure but the Zn-bound cysteines are reactive, are promising drug targets. Here, we aim to (i) identify labile Zn-sites in viral proteins using guidelines established from our previous work and (ii) assess if clinically safe Zn-ejecting agents could eject Zn(2+) from the predicted target site and thus inhibit viral replication. As proof-of-concept, we identified a labile Zn-site in the hepatitis C virus (HCV) NS5A protein and showed that the antialcoholism drug, disulfiram, could inhibit HCV replication to a similar extent as the clinically used antiviral agent, ribavirin. The discovery of a novel viral target and a new role for disulfiram in inhibiting HCV replication will enhance the therapeutic armamentarium against HCV. The strategy presented can also be applied to identify labile sites in other bacterial or viral proteins that can be targeted by disulfiram or other clinically safe Zn-ejectors.

Abstract
Most HCV-infected patients regularly consume alcohol. Alcoholic liver disease (ALD) and chronic hepatitis C virus (HCV) infection together are the most common causes of liver disease worldwide. Although both factors independently cause liver disease, they synergistically promote rapid liver disease progression with devastating outcomes for patients. This review focuses on the prevalence, clinical characteristics and molecular pathophysiologic mechanisms of HCV infection associated with alcohol abuse. Recent findings have centred on the synergistic effect of alcohol and HCV on viral replication, hepatocyte apoptosis, oxidative stress, alcohol-induced 'leaky gut', miR-122 and immune dysregulation. Clinical and basic research findings presented here summarize key scientific findings with the aim of highlighting potential areas for new therapies and identifying ways of optimizing current treatments for alcoholics with HCV infection.

Abstract
The aim of this study was to systematically evaluate state Medicaid policies for the treatment of hepatitis C virus (HCV) infection with sofosbuvir in the United States. Medicaid reimbursement criteria for sofosbuvir were evaluated in all 50 states and the District of Columbia. The authors searched state Medicaid Web sites between 23 June and 7 December 2014 and extracted data in duplicate. Any differences were resolved by consensus. Data were extracted on whether sofosbuvir was covered and the criteria for coverage based on the following categories: liver disease stage, HIV co-infection, prescriber type, and drug or alcohol use. Of the 42 states with known Medicaid reimbursement criteria for sofosbuvir, 74% limit sofosbuvir access to persons with advanced fibrosis (Meta-Analysis of Histologic Data in Viral Hepatitis [METAVIR] fibrosis stage F3) or cirrhosis (F4). One quarter of states require persons co-infected with HCV and HIV to be receiving antiretroviral therapy or to have suppressed HIV RNA levels. Two thirds of states have restrictions based on prescriber type, and 88% include drug or alcohol use in their sofosbuvir eligibility criteria, with 50% requiring a period of abstinence and 64% requiring urine drug screening. Heterogeneity is present in Medicaid reimbursement criteria for sofosbuvir with respect to liver disease staging, HIV co-infection, prescriber type, and drug or alcohol use across the United States. Restrictions do not seem to conform with recommendations from professional organizations, such as the Infectious Diseases Society of America and the American Association for the Study of Liver Diseases. Current restrictions seem to violate federal Medicaid law, which requires states to cover drugs consistent with their U.S. Food and Drug Administration labels.

Abstract
PURPOSE Alcohol is a confirmed risk factor of liver cancer. Yet, its dose-response function and synergistic effects with other risk factors remain unclear. METHODS We performed a meta-analysis on publications up to May 2014. A total of 112 publications were identified. The meta-relative risk (mRR) and the dose-response trend were calculated. Tests for heterogeneity, publication bias, and sensitivity analyses were performed. The synergy index (SI) was recorded or calculated, whenever possible. RESULTS Compared to individuals who never drank or drank at very low frequencies, the mRR for ever drinkers was 1.29 (95% confidence interval, CI 1.16-1.42) and 1.46 (95% CI 1.27-1.65) for case-control studies, and 1.07 (95% CI 0.87-1.27) for cohort studies. Being a current drinker was associated with an increased liver cancer risk in case-control studies (mRR = 1.55, 95% CI 0.38-2.73), but not in cohort studies (mRR = 0.86, 95% CI 0.74-0.97). The dose-response relation between alcohol and liver cancer was apparent with RR = 1.08 (95% CI 1.04-1.11) for 12 g/day (~1 drink), 1.54 (95% CI 1.36-1.74) for 50 g/day, 2.14 (95% CI 1.74-2.62) for 75 g/day, 3.21 (95% CI 2.34-4.40) for 100 g/day, and 5.20 (95% CI 3.25-8.29) for 125 g/day of alcohol consumption. There were synergistic effects of alcohol consumption with hepatitis (S = 2.14, 95% CI 1.31-2.98) and with diabetes (S = 3.57, 95% CI 2.29-4.84) on the risk of liver cancer, although this may be subject to publication bias. CONCLUSION Overall, one alcoholic drink per day (~12 g/day) may be associated with a 1.1 times higher liver cancer risk. Further studies on the synergistic effects of alcohol consumption and other major risk factors are warranted.

Abstract
Treating alcohol use disorders (AUD) is critical in individuals suffering from hepatitis C infection (HCV). Aside from psychosocial interventions, pharmacological treatment is effective for decreasing alcohol consumption and promoting abstinence. However, unique factors belonging to HCV-infected individuals, such as baseline hepatic vulnerability and possible ongoing hepatitis C treatment, complicate AUD drug therapy. The goal of this review is to systematically identify, summarize, and evaluate the existing evidence on the pharmacological management of AUD in HCV-infected individuals. MEDLINE, Embase, PsycINFO, and the Cochrane Central Register of Controlled Trials were searched for English- and French-language articles published from 1993 to December 2013. The search criteria focused on clinical trials and observational studies assessing the efficacy and/or safety of pharmacological management of AUD in patients infected with HCV. Of 421 identified studies, three were included for analysis. Two were observational studies assessing the safety of disulfiram. One was a randomized controlled trial assessing the efficacy and safety of baclofen. There is paucity of data regarding the efficacy and safety of pharmacological treatment of AUD in HCV-infected individuals, with studies being small series and showing significant heterogeneity. No strong recommendations can be made based on the current studies as to which pharmacological option should be preferred in this sub-population.

Abstract
Hepatitis C and alcohol are the most widespread causes of liver disease worldwide. Approximately 80% of patients with a history of hepatitis C and alcohol abuse develop chronic liver injury. Alcohol consumption in hepatitis C virus (HCV)-infected patients exacerbates liver disease leading to rapid progression of fibrosis, cirrhosis and even hepatocellular carcinoma. Hepatocytes are the main sites of HCV-infection and ethanol metabolism, both of which generate oxidative stress. Oxidative stress levels affect HCV replication and innate immunity, resulting in a greater susceptibility for HCV-infection and virus spread in the alcoholic patients. In this review paper, we analyze the effects of ethanol metabolism and other factors on HCV replication. In addition, we illustrate the mechanisms of how HCV hijacks innate immunity and how ethanol exposure regulates this process. We also clarify the effects of HCV and ethanol metabolism on interferon signaling-a crucial point for activation of anti-viral genes to protect cells from virus-and the role that HCV- and ethanol-induced impairments play in adaptive immunity which is necessary for recognition of virally-infected hepatocytes. In conclusion, ethanol exposure potentiates the suppressive effects of HCV on innate immunity, which activates viral spread in the liver and finally, leads to impairments in adaptive immunity. The dysregulation of immune response results in impaired elimination of HCV-infected cells, viral persistence, progressive liver damage and establishment of chronic infection that worsens the outcomes of chronic hepatitis C in alcoholic patients.

Abstract
Liver cancers are one of the deadliest known malignancies which are increasingly becoming a major public health problem in both developed and developing countries. Overwhelming evidence suggests a strong role of infection with hepatitis B and C virus (HBV and HCV), alcohol abuse, as well as metabolic diseases such as obesity and diabetes either individually or synergistically to cause or exacerbate the development of liver cancers. Although numerous etiologic mechanisms for liver cancer development have been advanced and well characterized, the lack of definite curative treatments means that gaps in knowledge still exist in identifying key molecular mechanisms and pathways in the pathophysiology of liver cancers. Given the limited success with current therapies and preventive strategies against liver cancer, there is an urgent need to identify new therapeutic options for patients. Targeting HCV and or alcohol-induced signal transduction, or virus-host protein interactions may offer novel therapies for liver cancer. This review summarizes current knowledge on the mechanistic development of liver cancer associated with HCV infection and alcohol abuse as well as highlights potential novel therapeutic strategies.

Abstract
UNLABELLED Alcoholic hepatitis (AH) is a distinct spectrum of alcoholic liver disease (ALD) with intense neutrophilic (polymorphonuclear; PMN) inflammation and high mortality. Although a recent study implicates osteopontin (SPP1) in AH, SPP1 is also shown to have protective effects on experimental ALD. To address this unsettled question, we examined the effects of SPP1 deficiency in male mice given 40% calories derived from ad libitum consumption of the Western diet high in cholesterol and saturated fat and the rest from intragastric feeding of alcohol diet without or with weekly alcohol binge. Weekly binge in this new hybrid feeding model shifts chronic ASH with macrophage inflammation and perisinusoidal and pericellular fibrosis to AH in 57% (15 of 26) of mice, accompanied by inductions of chemokines (Spp1, Cxcl1, and interleukin [Il]-17a), progenitor genes (Cd133, Cd24, Nanog, and epithelial cell adhesion molecule), PMN infiltration, and clinical features of AH, such as hypoalbuminemia, bilirubinemia, and splenomegaly. SPP1 deficiency does not reduce AH incidence and inductions of progenitor and fibrogenic genes, but rather enhances the Il-17a induction and PMN infiltration in some mice. Furthermore, in the absence of SPP1, chronic ASH mice without weekly binge begin to develop AH. CONCLUSION These results suggest that SPP1 has a protective, rather than causal, role for experimental AH reproduced in our model.

Abstract
Alcohol consumption is often associated with viral hepatitis. Although alcohol is known to worsen viral liver disease, the interactions between alcohol and viral hepatitis are not fully understood. Molecular alterations in the liver due to alcohol and viral hepatitis include effects on viral replication, increased oxidative stress, cytotoxicity, and a weakened immune response. Clinically, alcohol enhances disease progression and favors induction of primitive liver neoplasm. The use of new antivirals for hepatitis C and well-established drugs for hepatitis B will determine how viral hepatitis can be controlled in a large percentage of these patients. However, alcohol-related liver disease continues to represent a barrier for access to antivirals, and it remains an unresolved health issue.

Abstract
This paper reviews the role of the catabolism of HCV and signaling proteins in HCV protection and the involvement of ethanol in HCV-proteasome interactions. HCV specifically infects hepatocytes, and intracellularly expressed HCV proteins generate oxidative stress, which is further exacerbated by heavy drinking. The proteasome is the principal proteolytic system in cells, and its activity is sensitive to the level of cellular oxidative stress. Not only host proteins, but some HCV proteins are degraded by the proteasome, which, in turn, controls HCV propagation and is crucial for the elimination of the virus. Ubiquitylation of HCV proteins usually leads to the prevention of HCV propagation, while accumulation of undegraded viral proteins in the nuclear compartment exacerbates infection pathogenesis. Proteasome activity also regulates both innate and adaptive immunity in HCV-infected cells. In addition, the proteasome/immunoproteasome is activated by interferons, which also induce "early" and "late" interferon-sensitive genes (ISGs) with anti-viral properties. Cleaving viral proteins to peptides in professional immune antigen presenting cells and infected ("target") hepatocytes that express the MHC class I-antigenic peptide complex, the proteasome regulates the clearance of infected hepatocytes by the immune system. Alcohol exposure prevents peptide cleavage by generating metabolites that impair proteasome activity, thereby providing escape mechanisms that interfere with efficient viral clearance to promote the persistence of HCV-infection.
