Boyd J, Hayes K, Green D, Angus C, Holmes J. The contribution of health behaviour to socioeconomic inequalities in alcohol harm: Analysis of the UK biobank, a large cohort study with linked health outcomes. SSM Popul Health 2023; 23:101443. [PMID: 37334333 PMCID: PMC10275713 DOI: 10.1016/j.ssmph.2023.101443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 06/02/2023] [Accepted: 06/04/2023] [Indexed: 06/20/2023] Open
Abstract
This is the first study to use the UK Biobank database to: 1) test whether participants of a low socioeconomic position (SEP) are less likely to drink, but more likely to suffer alcohol-related harm, and 2) test the contribution of behavioural factors. The database contains health-related information from 500,000 UK residents that were recruited aged 40-69 between 2006 and 2010. Our analysis focuses on participants resident in England (86% of the total sample). We obtained baseline demographics, survey data regarding alcohol consumption and other behaviours, and linked death and hospital-admission records. The primary outcome was time from study entry to experiencing an alcohol-attributable event (hospital admission or death). The relationship between alcohol-attributable harm and five measures of SEP (area-level deprivation, housing tenure, employment status, household income and qualifications) was investigated using time-to-event analysis. Average weekly alcohol consumption, other drinking behaviours (drinking history and beverage preference), and lifestyle factors (BMI and smoking status) were added incrementally as covariates in nested regression models to investigate whether they could explain the relationship between harm and SEP. 432,722 participants (197,449 men and 235,273 women) were included in the analysis with 3,496,431 person-years of follow-up. Those of a low SEP were most likely to be never/former drinkers or high-risk drinkers. However, alcohol consumption could not explain experiences of alcohol-attributable harm between SEP groups (Hazard Ratio (HR) 1.48; 95% Confidence Interval 1.45-1.51, after adjusting for alcohol consumption). Drinking history, drinking mostly spirits, an unhealthy Body Mass Index and smoking all increased the risk of alcohol-attributable harm. However, these factors only partially explain SEP differences in alcohol harm as the HR for the most deprived vs the least deprived was still 1.28 after adjustment. This suggests that improving wider health behaviour of the most deprived could reduce alcohol-related inequalities. However, a substantial proportion of the variance in alcohol harm remains unexplained.

Fatty Liver Disease-Alcoholic and Non-Alcoholic: Similar but Different. Int J Mol Sci 2022; 23:ijms232416226. [PMID: 36555867 PMCID: PMC9783455 DOI: 10.3390/ijms232416226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 12/12/2022] [Accepted: 12/15/2022] [Indexed: 12/24/2022] Open
Abstract
In alcohol-induced liver disease (ALD) and in non-alcoholic fatty liver disease (NAFLD), there are abnormal accumulations of fat in the liver. This phenomenon may be related to excessive alcohol consumption, as well as the combination of alcohol consumption and medications. There is an evolution from simple steatosis to steatohepatitis, fibrosis and cirrhosis leading to hepatocellular carcinoma (HCC). Hepatic pathology is very similar regarding non-alcoholic fatty liver disease (NAFLD) and ALD. Initially, there is lipid accumulation in parenchyma and progression to lobular inflammation. The morphological changes in the liver mitochondria, perivenular and perisinusoidal fibrosis, and hepatocellular ballooning, apoptosis and necrosis and accumulation of fibrosis may lead to the development of cirrhosis and HCC. Medical history of ethanol consumption, laboratory markers of chronic ethanol intake, AST/ALT ratio on the one hand and features of the metabolic syndrome on the other hand, may help in estimating the contribution of alcohol intake and the metabolic syndrome, respectively, to liver steatosis.

Abstract
Constitutional, environmental, and genetic risk factors influence the development of alcohol-related cirrhosis. The amount of alcohol consumed and whether excessive drinking continues after the identification of pre-cirrhotic liver damage are key risk factors. Female sex, ethnicity, obesity, coffee consumption, cigarette smoking, and exposure to other causes of liver injury also influence the risk of disease development. More recently several genetic loci have been robustly associated with the risk for developing significant alcohol-related liver disease. It remains unclear whether additional risk factors are involved in the development of the clinical syndrome of alcoholic hepatitis, but the genetic evidence is suggestive.

Outcomes of excessive alcohol drinkers without baseline evidence of chronic liver disease after 15 years follow-up: Heavy burden of cancer and liver disease mortality. PLoS One 2021; 16:e0252218.

Abstract
Background Most long-term heavy drinkers do not have clinically evident chronic liver disease (CLD). However, at any time-point, their risk of developing CLD remains unknown. We aimed to evaluate the long-term outcomes of a group of heavy drinkers, without evidence of CLD at baseline. Methods A cohort of 123 long-term heavy drinkers without CLD were prospectively recruited in 2002 and retrospectively followed until 2018. Results At baseline (2002), median alcohol consumption was 271±203g/day during 21.5±20 years, 65% being abstinent during the previous 1.75±5 months. Patients were followed for 14±3 years. During follow-up, 53% reported any alcohol intake. Alcohol consumption during follow-up associated weakly with either 1- or 6-months previous abstinence at baseline. Until 2018, progression to CLD occurred in 6%, associating with years of alcohol intake during follow-up (OR 1.15 [1.01–1.31]) and baseline alkaline-phosphatase (OR 1.05 [1.01–1.10]). During follow-up, being abstinent for at least 1 year positively associated with CLD-free survival. 27% died (55% of cancer–mostly oropharyngeal cancer, 27% of cardiovascular disease, and 9% of liver disease), with a mean age of 71 years [69–74] (10 years less than the expected in the Portuguese population). Achieving abstinence for at least 1 year positively associated with overall survival, while smoking, and hepatic steatosis at baseline associated negatively. Conclusion Long-term heavy drinkers seemed to have a decreased life expectancy compared with the overall Portuguese population. Cancer was the main cause of death. Our results suggest that progression to CLD depends mostly on continued alcohol intake. Alcohol abstinence, even if temporary, seems to decrease the risks of CLD and mortality.

The role of alcohol use in the aetiology and progression of liver disease: A narrative review and a quantification. Drug Alcohol Rev 2021; 40:1377-1386. [PMID: 33783063 PMCID: PMC9389623 DOI: 10.1111/dar.13286] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 12/16/2020] [Accepted: 03/10/2021] [Indexed: 12/16/2022]
Abstract
Issues. Alcohol use has been shown to impact on various forms of liver disease, not restricted to alcoholic liver disease. Approach. We developed a conceptual framework based on a narrative review of the literature to identify causal associations between alcohol use and various forms of liver disease including the complex interactions of alcohol with other major risk factors. Based on this framework, we estimate the identified relations for 2017 for the USA. Key Findings. The following pathways were identified and modelled for the USA for the year 2017. Alcohol use caused 35 200 (95% uncertainty interval 32 800–37 800) incident cases of alcoholic liver cirrhosis. There were 1700 (uncertainty interval 1100–2500) acute hepatitis B and C virus (HBV and HCV) infections attributable to heavy-drinking occasions, and 14 000 (uncertainty interval 5900–19 500) chronic HBV and 1700 (uncertainty interval 700–2400) chronic HCV infections due to heavy alcohol use interfering with spontaneous clearance. Alcohol use and its interactions with other risk factors (HBV, HCV, obesity) led to 54 500 (uncertainty interval 50 900–58 400) new cases of liver cirrhosis. In addition, alcohol use caused 6600 (uncertainty interval 4200–9300) liver cancer deaths and 40 700 (uncertainty interval 36 600–44 600) liver cirrhosis deaths. Implications. Alcohol use causes a substantial number of incident cases and deaths from chronic liver disease, often in interaction with other risk factors. Conclusion. This additional disease burden is not reflected in the current alcoholic liver disease categories. Clinical work and prevention policies need to take this into consideration.

Abstract
This review describes the history of alcoholic liver disease from the beginning of the 1950s until now. It details how the hepatotoxicity of alcohol was discovered by epidemiology and basic research primarily by using new feeding techniques in rodents and primates. The article also recognizes the pioneering work of scientists who contributed to the understanding of the pathophysiology of alcoholic liver disease. In addition, clinical aspects, such as the development of diagnostics and treatment options for alcoholic liver disease, are discussed. Up-to-date knowledge of the mechanism of the disease in 2020 is presented.

Abstract
OBJECTIVES To systematically summarize the risk relationship between different levels of alcohol consumption and incidence of liver cirrhosis. METHODS MEDLINE and Embase were searched up to March 6, 2019, to identify case-control and cohort studies with sex-specific results and more than 2 categories of drinking in relation to the incidence of liver cirrhosis. Study characteristics were extracted and random-effects meta-analyses and meta-regressions were conducted. RESULTS A total of 7 cohort studies and 2 case-control studies met the inclusion criteria, providing data from 2,629,272 participants with 5,505 cases of liver cirrhosis. There was no increased risk for occasional drinkers. Consumption of one drink per day in comparison to long-term abstainers showed an increased risk for liver cirrhosis in women, but not in men. The risk for women was consistently higher compared to men. Drinking ≥5 drinks per day was associated with a substantially increased risk in both women (relative risk [RR] = 12.44, 95% confidence interval [CI]: 6.65-23.27 for 5-6 drinks, and RR = 24.58, 95% CI: 14.77-40.90 for ≥7 drinks) and men (RR = 3.80, 95% CI: 0.85-17.02, and RR = 6.93, 95% CI: 1.07-44.99, respectively). Heterogeneity across studies indicated an additional impact of other risk factors. DISCUSSION Alcohol is a major risk factor for liver cirrhosis with risk increasing exponentially. Women may be at higher risk compared to men even with little alcohol consumption. More high-quality research is necessary to elucidate the role of other risk factors, such as genetic vulnerability, body weight, metabolic risk factors, and drinking patterns over the life course. High alcohol consumption should be avoided, and people drinking at high levels should receive interventions to reduce their intake.

Abstract
The spectrum of alcoholic liver disease (ALD) is broad and includes alcoholic fatty liver, alcoholic steatohepatitis, alcoholic hepatitis, alcoholic fibrosis, alcoholic cirrhosis, and alcoholic hepatocellular carcinoma, best explained as a five-hit sequelae of injurious steps. ALD is not primarily the result of malnutrition as assumed for many decades but due to the ingested alcohol and its metabolic consequences although malnutrition may marginally contribute to disease aggravation. Ethanol is metabolized in the liver to the heavily reactive acetaldehyde via the alcohol dehydrogenase (ADH) and the cytochrome P450 isoform 2E1 of the microsomal ethanol-oxidizing system (MEOS). The resulting disturbances modify not only the liver parenchymal cells but also non-parenchymal cells such as Kupffer cells (KCs), hepatic stellate cells (HSCs), and liver sinusoidal endothelial cells (LSECs). These are activated by acetaldehyde, reactive oxygen species (ROS), and endotoxins, which are produced from bacteria in the gut and reach the liver due to gut leakage. A variety of intrahepatic signaling pathways and innate or acquired immune reactions are under discussion contributing to the pathogenesis of ALD via the five injurious hits responsible for disease aggravation. As some of the mechanistic steps are based on studies with in vitro cell systems or animal models, respective proposals for humans may be considered as tentative. However, sufficient evidence is provided for clinical risk factors that include the amount of alcohol used daily for more than a decade, gender differences with higher susceptibility of women, genetic predisposition, and preexisting liver disease. In essence, efforts within the last years were devoted to shed more light in the pathogenesis of ALD, much has been achieved but issues remain to what extent results obtained from experimental studies can be transferred to humans.

Abstract
Alcoholic liver disease (ALD) represents a spectrum of injury, ranging from simple steatosis to alcoholic hepatitis to cirrhosis. Regular alcohol use results in fatty changes in the liver which can develop into inflammation, fibrosis and ultimately cirrhosis with continued, excessive drinking. Alcoholic hepatitis (AH) is an acute hepatic inflammation associated with significant morbidity and mortality that can occur in patients with steatosis or underlying cirrhosis. The pathogenesis of ALD is multifactorial and in addition to genetic factors, alcohol-induced hepatocyte damage, reactive oxygen species, gut-derived microbial components result in steatosis and inflammatory cell (macrophage and neutrophil leukocyte) recruitment and activation in the liver. Continued alcohol and pro-inflammatory cytokines induce stellate cell activation and result in progressive fibrosis. Other than cessation of alcohol use, medical therapy of AH is limited to prednisolone in a subset of patients. Given the high mortality of AH and the progressive nature of ALD, there is a major need for new therapeutic intervention for this underserved patient population.

Abstract
Low-density lipoprotein receptor-related protein 6 (LRP6) is an important coreceptor in the Wnt/β-catenin upstream signaling pathway. Rs2302685 is a common functional mutation of LRP6 that has been previously associated with reduced alcoholic liver injury among alcoholic liver disease (ALD) patients, and the present research was designed to study the underlying mechanisms of that finding. A total of 107 ALD patients and 138 non-ALD patients were recruited from hospitalized alcoholics in China. Their venous blood samples were collected for DNA extraction and genotyped using Sequenom MassARRAY. We found that the rs2302685 mutation, which impaired the function of LRP6, was present in higher frequency among alcoholics with ALD than those without ALD. We also conducted a mouse model experiment in which LRP6(+/-) knockdown mice and LRP6(+/+) wild-type mice received daily intragastric doses of ethanol (2.4 g/kg) as well as a larger dose of ethanol (4 g/kg) every 7 days for 28 days. The mouse blood and liver specimens were subsequently collected for laboratory analysis, and cell experiments were performed to compare the inhibition, activation, over-expression, and siRNA of LRP6 in the treatment versus the control HL7702 cells. Expression of the targeted molecules was detected by real-time PCR or western blot analysis. Stably transfected cells with pRL3-CYP2E1 vector were used to further study the underlying mechanisms. The total bile acid (TBA), direct bilirubin, total bilirubin (TBIL), aspartate aminotransferase (AST), mitochondrial aspartate aminotransferase, and AST/ALT values were significantly lower in carriers of the rs2302685 mutation than in the wild-type patients, by 63.4, 60.6, 82.1, 44.8, 45.7, and 21.4%, respectively. Compared to the LRP6(+/+) wild-type mice, the LRP6(+/-) knockdown mice had lower ALT, TBIL, TBA, and ALB/GLO values, as well reduced liver tissue damage, in accordance with their reduced expressions of LRP6, β-catenin, and CYP2E1. In HL7702 cells exposed to ethanol, AST, ALT, lipid accumulation, and ROS generation decreased in cells that were treated with LRP6 inhibitors or siRNA but increased in cells treated with LRP6 activators or over-expressed LRP6. TCF1 was the transcriptional factor most likely to connect the LRP6-Wnt/β-catenin signaling pathway to the regulation of CYP2E1. We concluded that the LRP6 functional mutation rs2302685 contributes to individual differences in susceptibility to alcoholic liver injury related to the Wnt/β-catenin-TCF1-CYP2E1 signaling pathway.

Abstract
Alcoholic liver disease (ALD), a disorder caused by excessive alcohol consumption is a global health issue. More than two billion people consume alcohol in the world and about 75 million are classified as having alcohol disorders. ALD embraces a wide spectrum of hepatic lesions including steatosis, alcoholic steatohepatitis (ASH), fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). ALD is a complex disease where environmental, genetic, and epigenetic factors contribute to its pathogenesis and progression. The severity of alcohol-induced liver disease depends on the amount, method of usage and duration of alcohol consumption as well as on age, gender, presence of obesity, and genetic susceptibility. Genome-wide association studies and candidate gene studies have identified genetic modifiers of ALD that can be exploited as non-invasive biomarkers, but which do not completely explain the phenotypic variability. Indeed, ALD development and progression is also modulated by epigenetic factors. The premise of this review is to discuss the role of genetic variants and epigenetic modifications, with particular attention being paid to microRNAs, as pathogenic markers, risk predictors, and therapeutic targets in ALD.

Abstract
Alcoholic liver disease (ALD) is the most prevalent type of chronic liver disease worldwide. ALD can progress from alcoholic fatty liver (AFL) to alcoholic steatohepatitis (ASH), which is characterized by hepatic inflammation. Chronic ASH can eventually lead to fibrosis and cirrhosis and in some cases hepatocellular cancer (HCC). In addition, severe ASH (with or without cirrhosis) can lead to alcoholic hepatitis, which is an acute clinical presentation of ALD that is associated with liver failure and high mortality. Most individuals consuming >40 g of alcohol per day develop AFL; however, only a subset of individuals will develop more advanced disease. Genetic, epigenetic and non-genetic factors might explain the considerable interindividual variation in ALD phenotype. The pathogenesis of ALD includes hepatic steatosis, oxidative stress, acetaldehyde-mediated toxicity and cytokine and chemokine-induced inflammation. Diagnosis of ALD involves assessing patients for alcohol use disorder and signs of advanced liver disease. The degree of AFL and liver fibrosis can be determined by ultrasonography, transient elastography, MRI, measurement of serum biomarkers and liver biopsy histology. Alcohol abstinence achieved by psychosomatic intervention is the best treatment for all stages of ALD. In the case of advanced disease such as cirrhosis or HCC, liver transplantation may be required. Thus, new therapies are urgently needed.

Abstract
We designed a population-based retrospective cohort study to investigate the association between the event of alcohol intoxication and the risk of pyogenic liver abscess. The present study enrolled 245,076 patients with a history of alcohol intoxication from 2000 to 2010 and matched each of them with four comparison patients, with similar mean age and sex ratios. We determined the cumulative incidences and adjusted hazard ratios (aHRs) of liver abscess. A significant association was observed between alcohol intoxication and liver abscess. The incidence density rate of liver abscess was 3.47-fold greater in the alcohol intoxication (AI) cohort than in the non-AI cohort (12.2 vs. 3.43 per 10,000 person-years), with an adjusted HR (aHR) of 2.64 (95% CI = 2.26 to 3.08). This population-based study positively associated the event of alcohol intoxication with increased risk of liver abscess. Our findings warrant further large-scale and in-depth investigations in this area.

Abstract
OBJECTIVE To determine the differences in lifetime alcohol intake (LAI) and drinking patterns between patients with alcoholic liver disease (ALD) and alcohol use disorder (AUD) without notable liver injury and between males and females with ALD. METHODS Alcohol drinking patterns were assessed using the Lifetime Drinking History (LDH) a validated questionnaire, during an outpatient visit. Patients with AUD, currently in addiction treatment, were matched for gender and age (±5 years) with the ALD group. RESULTS A total of 39 patients with ALD (26 males and 13 females; median age 58) and equal number of AUD patients were included (median age 56 years). The onset age for alcohol drinking and duration of alcohol consumption was similar in ALD and AUD. The number of drinking days was higher in women with ALD than in women with AUD: 4075 [(3224-6504) versus 2092 (1296-3661), p = .0253]. The LAI and drinks per drinking day (DDD) were not significantly different between patients with ALD and AUD. Females with ALD had lower LAI than males with ALD: 32,934 (3224-6504) versus 50,923 (30,360-82,195), p = .0385, fewer DDD (p = .0112), and lower proportion of binge drinking as compared to males with ALD (p = .0274). CONCLUSIONS The total LAI was similar in patients with ALD and AUD. The number of drinking days over the lifetime was associated with the development of ALD in females. Females with ALD had significantly lower alcohol consumption than men with ALD despite similar duration in years of alcohol intake which supports the concept of female propensity of ALD.

Abstract
Primary tumors of the liver represent the fifth most common type of cancer in the world and the third leading cause of cancer-related death. Case-control studies from different countries report that chronic ethanol consumption is associated with an approximately 2-fold increased odds ratio for hepatocellular carcinoma (HCC). Despite the substantial epidemiologic data in humans demonstrating that chronic alcohol consumption is a major risk factor for HCC development, the pathways causing alcohol-induced liver cancer are poorly understood. In this overview, we summarize the epidemiological evidence for the association between alcohol and liver cancer, review the genetic, oncogenic, and epigenetic factors that drive HCC development synergistically with ethanol intake and discuss the essential molecular and metabolic pathways involved in alcohol-induced liver tumorigenesis.

Abstract
In this study, liver biopsy sections fixed in formalin and embedded in paraffin (FFPE) from patients with alcoholic hepatitis (AH) were used. The results showed that the expression of the SYK protein was up regulated by RNA-seq and real time PCR analyses in the alcoholic hepatitis patients compared to controls. The results were supported by using the IHC fluorescent antibody staining intensity morphometric quantitation. Morphometric quantification of fluorescent intensity measurement showed a two fold increase in SYK protein in the cytoplasm of the cells forming MDBs compared to surrounding normal hepatocytes. The expression of AKT1 was also analyzed. AKT1 is a serine/threonine-specific protein kinase that plays a key role in multiple cellular processes such as glucose metabolism, apoptosis, cell proliferation, transcription and cell migration. The AKT protein was also increased in hepatocyte balloon cells forming MDBs. This observation demonstrates the role of SYK and its subsequent effect on the internal signaling pathways such as PI3K/AKT as well as p70S6K, as a potential multifunctional target in protein quality control mechanisms of hepatocytes when ER stress is activated.

Abstract
The susceptibility to developing alcohol dependence and significant alcohol-related liver injury is determined by a number of constitutional, environmental and genetic factors, although the nature and level of interplay between them remains unclear. The familiality and heritability of alcohol dependence is well-documented but, to date, no strong candidate genes conferring increased risk have emerged, although variants in alcohol dehydrogenase and acetaldehyde dehydrogenase have been shown to confer protection, predominantly in individuals of East Asian ancestry. Population contamination with confounders such as drug co-dependence and psychiatric and physical co-morbidity may explain the essentially negative genome-wide association studies in this disorder. The familiality and hereditability of alcohol-related cirrhosis is not as well-documented but three strong candidate genes PNPLA3, TM6SF2 and MBOAT7, have been identified. The mechanisms by which variants in these genes confer risk and the nature of the functional interplay between them remains to be determined but, when elucidated, will undoubtedly increase our understanding of the pathophysiology of this disease. The way in which this genetic information could potentially inform patient management has yet to be determined and tested.

Abstract
Mallory-Denk Bodies (MDBs) are prevalent in various liver diseases including alcoholic hepatitis (AH) and are formed in mice livers by feeding DDC. Liver injury from alcohol administration causes balloon hepatocytes and MDB formation impeding liver regeneration. By comparing AH livers where MDBs had formed with normal liver transcriptomes obtained by RNA sequencing (RNA-Seq), there was significant upregulation of BRCA1-mediated signaling and G1/S cell cycle checkpoint pathways. The transcriptional architecture of differentially expressed genes from AH livers reflected step-wise transcriptional changes progressing to AH. Key molecules such as BRCA1, p15 and p21 were significantly upregulated both in AH livers and in the livers of the DDC re-fed mice model where MDBs had formed. The increase of G1/S cell cycle checkpoint inhibitors p15 and p21 results in cell cycle arrest and inhibition of liver regeneration, implying that p15 and p21 could be exploited for the identification of specific targets for the treatment of liver disease. Provided here for the first time is the RNA-Seq data that represents the fully annotated catalogue of the expression of mRNAs. The most prominent alterations observed were the changes in BRCA1-mediated signaling and G1/S cell cycle checkpoint pathways. These new findings expand previous and related knowledge in the search for gene changes that might be critical in the understanding of the underlying progression to the development of AH.

Abstract
BACKGROUND The outcomes of hepatic resection in intrahepatic cholangiocarcinoma (ICC) patients with diabetes mellitus (DM), hypertension (HT), and dyslipidemia (DL) (metabolic components) remain unclear. METHODS The outcomes of 43 ICC patients without known risk factors for ICC who underwent hepatic resection were retrospectively reviewed. These patients were divided into three groups: those followed-up for metabolic components at least every 6 months (follow-up group, n=16), those not followed-up for metabolic components (no follow-up group, n=14), and those without metabolic components (control group, n=13). RESULTS In the follow-up group, 13 (81%) patients were further examined for ICC during follow-up because of abnormal screening results, such as elevated serum gamma-glutamyl transpeptidase and carbohydrate antigen 19-9 (CA19-9) concentrations or detection of hepatic tumor on ultrasonography and/or computed tomography, whereas most patients in the other two groups exhibited ICC-related symptoms. No patient in the follow-up group exhibited lymph node metastasis, whereas 43% of those in the no follow-up group and 46% in the control group had lymph node metastasis (p=0.005 and 0.004 vs. the follow-up group, respectively). All 16 patients in the follow-up group were diagnosed as International Union Against Cancer pathologic stage I or II (early stage). There were no significant differences in the incidence of postoperative recurrence between the three groups; however, the incidence of extrahepatic recurrence was lower in the follow-up group than in the no follow-up group and the control group (13% vs. 78% vs. 63%, p=0.0232). The 1-, 3-, and 5-year overall survivalrates in the follow-up group were better than those in the no follow-up and control groups (93/93/66% vs. 77/34/34% and 85/24/0%, p=0.034 and 0.001, respectively). CONCLUSIONS Routine measurement of serum gamma-glutamyl transpeptidase and/or CA19-9 levels and imaging examinations every 12 months (or 6 months, if possible) are recommended during follow-up for DM, HT, and DL to detect ICC at an early stage.

Cunningham JK, Solomon TA, Muramoto ML. Alcohol use among Native Americans compared to whites: Examining the veracity of the 'Native American elevated alcohol consumption' belief. Drug Alcohol Depend 2016; 160:65-75. [PMID: 26868862 DOI: 10.1016/j.drugalcdep.2015.12.015] [Citation(s) in RCA: 78] [Impact Index Per Article: 9.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2015] [Revised: 12/10/2015] [Accepted: 12/12/2015] [Indexed: 02/07/2023]
Abstract
BACKGROUND This study uses national survey data to examine the veracity of the longstanding belief that, compared to whites, Native Americans (NA) have elevated alcohol consumption. METHODS The primary data source was the National Survey on Drug Use and Health (NSDUH) from 2009 to 2013: whites (n=171,858) and NA (n=4,201). Analyses using logistic regression with demographic covariate adjustment were conducted to assess differences in the odds of NA and whites being alcohol abstinent, light/moderate drinkers (no binge/heavy consumption), binge drinkers (5+ drinks on an occasion 1-4 days), or heavy drinkers (5+ drinks on an occasion 5+ days) in the past month. Complementary alcohol abstinence, light/moderate drinking and excessive drinking analyses were conducted using Behavioral Risk Factor Surveillance System (BRFSS) data from 2011 to 2013: whites (n=1,130,658) and NA (n=21,589). RESULTS In the NSDUH analyses, the majority of NA, 59.9% (95% CI: 56.7-63.1), abstained, whereas a minority of whites, 43.1% (CI: 42.6-43.6), abstained-adjusted odds ratio (AOR): 0.64 (CI: 0.56-0.73). Approximately 14.5% (CI: 12.0-17.4) of NA were light/moderate-only drinkers, versus 32.7% (CI: 32.2-33.2) of whites (AOR: 1.90; CI: 1.51-2.39). NA and white binge drinking estimates were similar-17.3% (CI: 15.0-19.8) and 16.7% (CI: 16.4-17.0), respectively (AOR: 1.00; CI: 0.83-1.20). The two populations' heavy drinking estimates were also similar-8.3% (CI: 6.7-10.2) and 7.5% (CI: 7.3-7.7), respectively (AOR: 1.06; CI: 0.85-1.32). Results from the BRFSS analyses generally corroborated those from NSDUH. CONCLUSIONS In contrast to the 'Native American elevated alcohol consumption' belief, Native Americans compared to whites had lower or comparable rates across the range of alcohol measures examined.

Abstract
Background Though the type of alcohol consumed is not thought to be associated with alcoholic liver disease (ALD), some studies have shown a beverage-specific effect. In the present study, we aim to study the effects of locally brewed alcoholic beverages on the development of liver disease. Patients and methods This cross-sectional study was conducted at the internal medicine department of a university hospital in Nepal. All patients classified as having either alcohol abuse or alcohol dependence by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition were evaluated for the presence of ALD. Results A total of 1,500 patients were screened, of which, 447 patients had ALD. Chronic liver disease (CLD) was detected in 144 patients (9.6%). Most of the patients consumed homemade locally brewed alcohol. On multivariate analysis, the following variables were found to be significantly associated with CLD: male sex (odds ratio [OR]: 1.81; 95% confidence interval [CI]: 1.12–2.94; P=0.02): rakshi consumption ≥30 units (OR: 2.53; 95% CI: 1.07–6.01; P=0.04); and tongba consumption (OR: 3.02; 95% CI: 1.22–7.50; P=0.02). Conclusion There was a significant increase in the risk of developing ALD with the consumption of rakshi and tongba after adjusting for total units consumed. The absence of striking differences between our patients with CLD and non-CLD patients with regards to the amount of alcohol consumed demonstrates that, although alcohol consumption is a prerequisite for the development of ALD, other factors like type of alcoholic beverage consumed may be involved.

PNPLA3 Gene Polymorphism Is Associated With Predisposition to and Severity of Alcoholic Liver Disease. Am J Gastroenterol 2015; 110:846-56. [PMID: 25964223 DOI: 10.1038/ajg.2015.137] [Citation(s) in RCA: 102] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2014] [Accepted: 04/01/2015] [Indexed: 12/11/2022]
Abstract
OBJECTIVES The genetic polymorphism with an isoleucine-to-methionine substitution at position 148 (rs738409 C>G) in the patatin-like phospholipase domain protein 3 (PNPLA3) gene confers risk of steatosis. PNPLA3 polymorphism is shown to be associated with alcoholic liver disease (ALD). We performed a systematic review and meta-analysis to examine association of this genetic polymorphism with ALD spectrum and its severity. METHODS Medline, Embase, and Cochrane Library were searched for studies on association of PNPLA3 polymorphism and ALD spectrum: alcoholic fatty liver (AFL), alcoholic liver injury (ALI), alcoholic cirrhosis (AC), and hepatocellular carcinoma (HCC). Pooled data are reported as odds ratio (OR) with 95% confidence interval. Heterogeneity was assessed using the I(2) statistics and publication bias using Egger's test and Begg and Mazumdar's test. Individual participant data obtained from five studies were used for subgroup analyses. RESULTS Among 10 studies included in this pooled analysis, compared with controls, OR for rs738409 CG and GG among ALI patients was 1.45 (1.24-1.69) and 2.22 (1.50-3.28), respectively, compared with CC. Respective OR among AC patients was 2.09 (1.79-2.44) and 3.37 (2.49-4.58) and among AC patients with HCC was 2.87 (1.61-5.10) and 12.41 (6.99-22.03). Data for AFL were inconsistent. Among ALD patients, OR of CG and GG genotypes was 2.62 (1.73-3.97) and 8.45 (2.52-28.37), respectively, for AC compared with fatty liver (FL) patients. Similar OR for AC compared with ALI was 1.98 (1.24-3.17) and 3.86 (1.18-12.60). The OR for CG and GG genotypes among AC patients for HCC occurrence was 1.43 (0.76-2.72) and 2.81 (1.57-5.01), respectively. Individual participant data analysis showed age to predispose to AC among ALI patients. CONCLUSIONS PNPLA3 genetic polymorphism (rs738409 C>G) is associated with increased risk for the entire spectrum of ALD among drinkers including ALI, AC, and HCC. Studies are needed to clarify association of PNPLA3 polymorphism and steatosis in alcoholics. PNPLA3 gene may potentially be a therapeutic target in ALD.

Moderate alcohol consumption diminishes the development of non-alcoholic fatty liver disease (NAFLD) in ob/ob mice. Eur J Nutr 2015; 55:1153-64.

Abstract
PURPOSE Using ob/ob mice as a model of non-alcoholic fatty liver disease (NAFLD), we investigated the effect of moderate alcohol intake on the development of NAFLD and molecular mechanisms involved. METHODS Ob/ob mice were fed water or ethanol solution (2.5 g/kg body weight/day) for 6 weeks, and markers of liver injury, insulin signalling and adiponectin in visceral adipose tissue were determined. RESULTS Whereas bodyweight and the degree of liver steatosis did not differ among ob/ob mouse groups, those consuming ethanol had markedly less macrovesicular hepatic fat accumulation, inflammatory alterations and significantly lower transaminase levels. Despite similarly elevated protein levels of tumour necrosis factor α, protein concentrations of plasminogen activator inhibitor 1 were significantly lower in livers of ob/ob mice consuming ethanol in comparison with controls. The hepato-protective property of moderate alcohol ingestion in ob/ob mice was associated with an induction of the sirtuin-1/adiponectin-signalling cascade in visceral fat tissue and an activation of Akt in the liver. Similar effects of moderate alcohol exposure were also found in vitro in 3T3-L1 and AML-12 cells. CONCLUSION These data suggest that moderate alcohol intake may diminish the development of NAFLD through sirtuin-1/-adiponectin-dependent signalling cascades.

Abstract
BACKGROUND & AIMS Alcohol is the main contributing factor of alcoholic cirrhosis, but less is known about the significance of drinking pattern. METHODS We investigated the risk of alcoholic cirrhosis among 55,917 participants (aged 50-64 years) in the Danish Cancer, Diet, and Health study (1993-2011). Baseline information on alcohol intake, drinking pattern, and confounders was obtained from a questionnaire. Follow-up information came from national registers. We calculated hazard ratios (HRs) for alcoholic cirrhosis in relation to drinking frequency, lifetime alcohol amount, and beverage type. RESULTS We observed 257 and 85 incident cases of alcoholic cirrhosis among men and women, respectively, none among lifetime abstainers. In men, HR for alcoholic cirrhosis among daily drinkers was 3.65 (95% CI: 2.39; 5.55) compared to drinking 2-4 days/week. Alcohol amount in recent age periods (40-49 and 50-59 years) was associated with an increased risk, whereas the amount in 20-29 and 30-39 years was not. In men drinking 14-28 drinks/week, HR was 7.47 (95% CI: 1.68; 33.12), 3.12 (95% CI: 1.53; 6.39), and 1.69 (95% CI: 0.79; 3.65) in drinkers of little (<1% of weekly amount), some (1-15%), and mostly wine (50-100%), compared to drinking <14 drinks/week. In general, results were similar for women. CONCLUSIONS In men, daily drinking was associated with an increased risk of alcoholic cirrhosis. Recent alcohol consumption rather than earlier in life was associated with risk of alcoholic cirrhosis. Compared to beer and liquor, wine might be associated with a lower risk of alcoholic cirrhosis.

Abstract
OBJECTIVE The precise relationship between alcohol intake and metabolic syndrome (MetS) is still unclear, and the results from previous studies have been inconclusive. Thus, we examined the effect of alcohol intake on the risk of MetS in men in order to gain more information on a potential relationship. METHODS This study included 22,349 men who were divided into four groups according to their average alcohol intake [non-, light (less than 20 g ethanol/day), heavy (equal or more than 20 g and less than 60 g ethanol/day) and very heavy (equal and greater than 60 g ethanol/day) drinkers]. We measured each subject's body mass index (BMI), waist circumference and blood pressure (BP) and conducted a blood test to obtain a complete blood count and biochemical panel. These results were used to obtain the MetS prevalence. Additionally, fatty liver was diagnosed using abdominal ultrasonography. RESULTS Light drinkers had smaller waist circumferences. Heavy and very heavy drinkers had larger waist circumferences, a higher BMI, a higher BP, higher fasting plasma glucose levels, higher triglycerides (TG) levels and higher high-density lipoprotein (HDL) cholesterol levels while they had lower low-density lipoprotein cholesterol levels than nondrinkers. The prevalence of high BP, hyperglycemia and high TG was significantly higher in heavy and very heavy drinkers than in nondrinkers. The prevalence of low HDL cholesterol levels decreased with an increase in alcohol consumption. The prevalence of MetS was significantly lower in light drinkers and higher in very heavy drinkers compared with nondrinkers. CONCLUSION Alcohol intake significantly influences the risk of MetS in men. A significant association was seen between an alcohol intake of 60 g/day or higher and the prevalence of MetS.

Abstract
OBJECTIVES It has been reported that chlorinated organic solvent is a cause of hepatitis. METHODS we investigate clinical and pathological findings of a patient with severe acute hepatitis who was exposed to chlorinated organic solvents. RESULTS A 34-year-old man who was exposed to chlorinated organic solvents including dichloromethane, 1,2-dichloropropane, and trichloroethylene, presented with general fatigue, vomiting, and diarrhea. At admission, his laboratory test results showed extremely elevated aspartate aminotransferase (4,872 IU/l), alanine aminotransferase (3,000 IU/l), and lactate dehydrogenase (11,600 IU/l) levels and a prothrombin level below normal (41%). No encephalopathy was noted. These findings were indicative of severe acute hepatitis. Viral hepatitis, autoimmune hepatitis, alcoholic disease, bile duct disease, and viral infection were excluded as causes of hepatitis by clinical, laboratory, and imaging findings. After diagnosis, the patient was administered fresh frozen plasma and glucagon-insulin therapy. Liver function recovered within a few weeks, and a liver biopsy performed 25 days after admission showed the recovery phase after acute liver damage. CONCLUSIONS These clinical and pathological findings indicate that exposure to chlorinated organic solvents may have induced severe acute hepatitis in this patient.

Abstract
BACKGROUND Alcoholism is a health problem not only in developed countries but also in developing countries. Cirrhosis due to alcohol is a common cause of death among individuals abusing alcohol. A better knowledge of the spectrum of alcoholic liver diseases, its clinical, biochemical and histopathological features could result in early detection and prevention of alcoholic liver diseases before it's catastrophic and life threatening effects. MATERIALS AND METHODS A total of 200 patients with alcoholic liver diseases were studied with respect to alcohol consumption, clinical features, biochemical and histopathological changes. The clinical features, biochemical parameters, and histopathology of liver including Ishak's modified histological activity index (HAI) were correlated with the amount and duration of alcohol consumed. RESULT Majority of the patients were in the age group of 40-49 years and all the cases were males. Majority consumed alcohol of about 75-90 grams per day for a duration of 10-12 years. Anorexia and jaundice were the most common symptom and clinical finding respectively. Hyperbilirubinemia and hypoalbuminemia were the most common abnormalities observed in liver function tests. Advanced HAI stages with features of cirrhosis were most frequent histo-pathological finding noted in this study. Clinico-biochemical profile was significantly correlated with degree of alcohol ingestion as well as with liver histopathology. CONCLUSION The wide prevalence of alcoholic liver disease including cirrhosis among Indian males was noted with significantly lower quantity and duration of alcohol ingestion. The severity of liver damage is directly proportional to the quantity and duration of alcohol consumed. Clinical features and biochemical changes may forecast the liver histopathology among the patients of alcoholic liver disease.

Abstract
The possible protective role of ethanolic extract of A. indica tuber (EEAIT) in hepatotoxicity and apoptosis of liver caused by alcohol in rats was investigated. Treatment of rats with alcohol (3 g ethanol per kg body weight per day for 15 days intraperitoneally) produced marked elevation of liver biomarkers such as serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (γ-GT), and total bilirubin levels which were reduced by EEAIT in a dose-dependent manner. Furthermore, EEAIT improved antioxidant status (MDA, NO, and GSH) and preserved hepatic cell architecture. Simultaneous supplementation with EEAIT significantly restored hepatic catalase (CAT) and superoxide dismutase (SOD) activity levels towards normal. The studies with biochemical markers were strongly supported by the histopathological evaluation of the liver tissue. EEAIT also attenuated apoptosis and necrosis features of liver cell found in immunohistochemical evaluation. HPLC analysis of the extract showed the presence of three major peaks of which peak 2 (RT: 33.33 min) contains the highest area (%) and UV spectrum analysis identified it as flavonoids. It is therefore suggested that EEAIT can provide a definite protective effect against chronic hepatic injury caused by alcohol in rats, which may mainly be associated with its antioxidative effect.

Gender medicine focuses on the patho-physiological, clinical, prevention and treatment differences in diseases that are equally represented in men and women. The purpose of gender medicine is to ensure that each individual man and woman receives the best treatment possible based on scientific evidence. The concept of “gender” includes not only the sexual characteristics of individuals but also physiological and psychological attributes of men and women, including risk factors, protective/aggravating effects of sexual hormones and variances linked to genetics and corporal structures that explain biological and physiological differences between men and women. It is very important to consider all the biological, physiological, functional, psychological, social and cultural characteristics to provide patients with individualized disease management. Herein, we critically analyze the literature regarding gender differences for diseases and acquired conditions of the most representative hepatic pathologies: primary biliary cirrhosis, autoimmune hepatitis, primary sclerosing cholangitis, non alcoholic fatty liver disease and alcoholic liver disease, and viral chronic hepatitis B and C. The last section addresses hemochromatosis, which is a prevalent iron overload disorder in the Caucasian population. This review aims to describe data from the literature concerning viral chronic hepatitis during pregnancy, management during pregnancy and delivery, and new effective drugs for the prevention of maternal infection transmission without significant adverse effects or complications.

Abstract
CONTEXT Tarvada [Cassia auriculata Linn. (Caesalpiniaceae)] is used against liver ailments in Indian folk medicine, but there is a lack of scientific evidence for this traditional claim. OBJECTIVE The present study investigated the protective effect of methanol extract of tarvada (MECA) roots on ethanol and antitubercular drug induced hepatotoxicity in rats. MATERIALS AND METHODS In the therapeutic model, ethanol (40%, 4 g/kg b.w., p.o.) was administered to rats for 21 days and the intoxicated rats were treated with MECA (300 and 600 mg/kg, b.w.) and silymarin (100 mg/kg, b.w.) for next 7 days. In the prophylactic model, MECA and silymarin were administered simultaneously along with a combination of isoniazid (27 mg/kg, b.w.), rifampicin (54 mg/kg, b.w.) and pyrazinamide (135 mg/kg, b.w.) for 30 days. After the study duration, serum levels of AST, ALT, ALP, total bilirubin, total cholesterol, total protein, albumin were estimated along with hepatic catalase (CAT), reduced glutathione (GSH), superoxide dismutase (SOD), malondialdehyde (MDA) and liver histopathology in each group. RESULTS Administration of tarvada root extract significantly (p < 0.01 and p < 0.05) lowered the elevated levels of serum AST, ALT, ALP, total bilirubin, total cholesterol, total protein and restored the abnormal levels of enzymatic antioxidants and MDA in liver due to toxicant administration in a dose-dependent manner. These results were confirmed by histopathological analysis. DISCUSSION AND CONCLUSION Results suggest that tarvada root extract possess potent hepatoprotective activity against ethanol and antitubercular drug-induced hepatotoxicity in rats, which could be due to an inhibition of hepatic metabolizing enzymes and antioxidant activity.

Abstract
Background: Alcoholic cirrhosis is often associated with impaired lipid metabolism. However, there are only a few studies regarding lipid profile in alcoholic cirrhosis that have been undertaken in India. The aim of the study is to assess the degree of alteration of serum lipid profile in alcoholic cirrhotic patients and also to detect its relationship with the age of the patients and the alcohol consumption pattern. Patients and Methods: This cross-sectional study was conducted in a teaching hospital of north-eastern India for 1 year with 100 patients with alcoholic cirrhosis (cases) and 50 healthy individuals (controls) without history of alcohol consumption. A questionnaire of personal characteristics including history of alcoholism was completed for each patient. Serum lipid profile (total, low-density lipoprotein (LDL), high-density lipoprotein (HDL) cholesterol and triglyceride) was recorded for each case and control. t test of significance was applied for statistical analysis. Results: Majority of the cases were in the 41-50 years age group. There was no relationship of cirrhosis with the type of alcoholic beverage, but a definite relationship was observed with the quantity and the duration of alcohol consumption. In patients with cirrhosis, the total serum cholesterol level was decreased. There was a significant decrease in serum HDL and LDL cholesterol compared with the control group ( P < 0.001). However, the serum triglyceride levels were significantly increased in alcoholic cirrhotic patients compared with the control group ( P < 0.001). Conclusion: In this study, we found that there was marked alteration of serum lipid profile values in patients with alcoholic cirrhosis compared with normal, non-cirrhotic individuals. Therefore, a search for lipid profile abnormality should be performed in every cirrhotic patient.

Abstract
Alcoholic hepatitis is a form of severe, cholestatic liver disease that results from consumption of large amount of alcohol during a sustained period of time in a subset of alcoholics. Symptoms could be mild and nonspecific to more severe. The diagnosis of alcoholic hepatitis can be made with a thorough history, physical examination, and review of laboratory results. Liver biopsy is confirmatory but generally not indicated for the diagnosis. Abstinence is the key form of therapeutic intervention. Despite variable results in clinical trials, corticosteroids and pentoxifylline seem to provide moderate survival benefit. Liver transplantation in acute alcoholic hepatitis is contentious.

Abstract
Ethanol abuse and chronic ethanol consumption remains a major public health problem and is responsible for a high rate of morbidity. Alcohol-induced fatty liver generally begins as hepatic steatosis, and if the cause persists, this invariably progresses to steatohepatitis and cirrhosis. The original biochemical explanation for an alcoholic fatty liver centered on the ability of ethanol metabolism to shift the redox state of the liver and inhibit fatty acid oxidation. Subsequent studies found repression of fatty acid oxidation and that the induction of lipogenesis can occur in alcoholic conditions. Ethanol activates sterol regulatory element binding protein 1, inducing a battery of lipogenic enzymes. These effects may be due in part to inhibition of AMP-dependent protein kinase, reduction in plasma adiponectin or increased levels of TNF-α the liver. They in turn activate lipogenic pathways and inhibit fatty acid oxidation. Besides the fatty acid synthesis and oxidation, ethanol also alters lipid droplet (LD, the storage form of triglycerides, TG) metabolism in hepatocytes and very low-density lipoprotein (VLDL) secretion from liver. Because steatosis is now regarded as a significant risk factor for advanced liver pathology, an understanding of the molecular mechanisms in its etiology provides new therapeutic targets to reverse the alcoholic fatty liver.

Abstract
Mallory-Denk Bodies (MDB) are important as investigators, suggesting MDB as an indicator of the histologic severity of chronic hepatitis, causes of which include hepatitis C, primary biliary cirrhosis (PBC), and nonalcoholic fatty liver disease (NAFLD). Matteoni et al scored MDB in patients with NAFLD as none, rare and many, and reported that MDB plays a prominent role in this classification scheme in an earlier classification system. In this study, we evaluated 258 patients with chronic hepatitis due to metabolic, autoimmune and viral etiologies. Liver biopsy samples were evaluated with hematoxylin and eosin, periodic acid-Schiff-diastase, Gordon and Sweet’s reticulin, Masson’s trichrome, and iron stains. Both staging and grading were performed. Additionally, MDB were evaluated and discussed for each disease. We examined patients with nonalcoholic steatohepatitis (NASH; 50 patients), alcoholic hepatitis (10 patients), PBC (50 patients), Wilson disease (WD; 20 patients), hepatitis B (50 patients), hepatitis C (50 patients) and hepatocellular carcinoma (HCC; 30 patients). Frequency of MDB was as follows; NASH: 10 patients with mild in 60% and moderate in 40% and observed in every stage of the disease and frequently seen in zone 3. PBC: 11 patients with mild in 10%, moderate in 70%, and cirrhosis in 20%, and frequently seen in zone 1. WD: 16 patients with moderate and severe in 60% and cirrhosis in 40% and frequently seen in zone 1. Hep B: 3 patients with mild in 66% and severe in 34%. Hep C: 7 patients with mild in 40% and moderate in 60% and observed in every stage. HCC: 3 patients with hep B in 2 patients. We found that there is no relationship between MDB and any form of chronic hepatitis regarding histologic severity such as alcoholic steatohepatitis and NAFLD and variable zone distribution by etiology.

Abstract
GOALS We describe the epidemiology of outpatients newly diagnosed with chronic alcoholic liver disease and describe predictors of cirrhosis and referral for specialty care. BACKGROUND Alcohol is a major cause of liver disease in the United States. Most previous work has described hospitalized patients. STUDY Participants were identified through prospective population-based surveillance in gastroenterology practices Multnomah County, Oregon and New Haven County, Connecticut; and primary care and gastroenterology practices from Kaiser Permanente Northern California in Alameda County during 1999 to 2001. Patients were interviewed, a blood specimen obtained, and their medical record reviewed. RESULTS We identified 82 patients from gastroenterology practices with newly diagnosed alcoholic liver disease. Their median age was 50.0 years. 72.0% were male and 79.3% were White. The median age at initiation of alcohol use was 17.0 years. 43.9% of patients had evidence of cirrhosis at the time of diagnosis. Only 40.2% reported alcohol as the cause of their liver disease. Patients with cirrhosis were more likely to be older, have a higher median number of years of heavy alcohol consumption, and to have been hospitalized for a liver-related complication than noncirrhotic patients. An additional 83 primary care patients were more likely to be older, to be drinking alcohol at study interview, and to not have cirrhosis than patients referred for gastroenterology care. CONCLUSIONS Patients with alcoholic liver disease may present at a late stage and may not identify alcohol as a cause for their liver disease. Improved patient screening and education may limit morbidity and mortality.

Abstract
OBJECTIVE The objectives of this study were to investigate the incidence, aetiology and mortality of liver cirrhosis in Iceland and in Gothenburg in Sweden. Further objectives were prognosis in relation to different aetiologies and to evaluate the relationship between alcohol consumption in these countries and the incidence of alcoholic cirrhosis in recent decades. The incidence and mortality of liver cirrhosis in Iceland has been reported to be the lowest in the Western world. There are very few data on aetiology, incidence and prognosis among cirrhotics in Sweden. MATERIAL AND METHODS All patients diagnosed with liver cirrhosis in Gothenburg (600,000 inhabitants) and Iceland (300,000 inhabitants) during the period 1994-2003 were included. RESULTS A total of 918 patients in Gothenburg and 98 in Iceland were identified. The annual incidence in Gothenburg was 15.3+/-2.4/100,000 compared to 3.3+/-1.2/100,000 in Iceland (p<0.0001). In Gothenburg, 69% were male and in Iceland 52% (p<0.001). In Gothenburg, 50% of the patients had alcoholic cirrhosis compared to 29% in Iceland (p<0.0001). In Gothenburg, the patients had a higher Child-Pugh score (9.0) (SD 2.5) compared to Iceland (7.3) (SD 2.7) (p<0.0001). There was no difference in survival between patients with alcoholic liver disease and those with other aetiologies. CONCLUSIONS The incidence of liver cirrhosis is low in Iceland, i.e. 24% of the incidence in Gothenburg, due to the lower incidence of alcoholic and hepatitis C cirrhosis in Iceland. No increasing trends in the incidence of cirrhosis in these two countries were observed during the study period.

Abstract
AbstractTwo issues are raised. (1) What is the nature of the drug effect Heyman thinks confers value to drugs? (2) What is the evidence that drug use decreases the value of drugs and of conventional incentives over the long-term? There is considerable evidence for the opposite; a persistent increase in the sensitivity of neural systems that mediate drug value.

Abstract
AbstractFor use in applied settings, the melioration model will need to incorporate changes in the shapes of local value functions over time, treat current value as a continuous function of time since previous choices, and take into account discounting of the effects of current behavior on future value. The policy implications of the model for regulating drugs are limited.

Abstract
AbstractHeyman's analysis of addiction in terms of matching to local relative value can be supplemented by stimulus-control processes. Stimulus equivalence can broaden the set of situations that occasion addictive behavior, and the situation-reinforcer correlation can enhance its persistence. The joint effects of stimulus-control and reinforcement processes may complicate treatment.
