Harmful use of alcohol is one of the top five risks for burden of disease globally and in Europe; in 2012, 3.3 million net deaths (approximately 6% of all global deaths) were attributable to this risk factor. It is also linked to the development of a wide spectrum of alcohol use disorders, ranging from mild manifestations to a severe disease known as alcohol dependence. Alcohol dependence is a progressive, chronic, and relapsing brain disease resulting from the prolonged effects of alcohol on the brain. Alcohol dependence imposes a significant societal burden, with indirect societal costs reaching up to 0.64% of European countries׳ annual gross domestic product. With these facts in mind, it is important to recognize and manage alcohol dependence. Although the biological mechanisms behind the development of alcohol dependence are not fully known, factors that have been shown to influence its development include genetic predisposition, psychological problems, and social interactions. Alcohol use has also been linked to the development of hypertension, liver cirrhosis, chronic pancreatitis, multiple types of cancer, and psychiatric comorbidities such as depression and anxiety disorders. With such severe effects on both individuals and society, it is important to recognize the characteristic signs and symptoms of alcohol dependence and explore new ways to better manage patients with this brain disease. Effective treatment approaches for alcohol dependence include biological, behavioral, and social components addressing the multiple aspects of this disease. Comprehensive, educational platforms in which to explore the many facets of this disease such as the Progress in Mind: Focus on Alcohol Use Disorders Resource Centre, will provide clinicians with the tools necessary for recognizing patients with alcohol dependence and managing their disease along with related comorbidities.

Acamprosate: A prototypic neuromodulator in the treatment of alcohol dependence
Heyser, Charles J.
2010-01-01
Alcoholism is one of the most prevalent substance dependence disorders in the world. Advances in research in the neurobiological mechanisms underlying alcohol dependence have identified specific neurotransmitter targets for the development of pharmacological treatments. Acamprosate, marketed under the brand name Campral, is an orally administered drug available by prescription in the U.S. and throughout much of the world for treating alcohol dependence. Its safety and efficacy have been demonstrated in numerous clinical trials worldwide. Here we provide an overview of acamprosate in the context of the neurobiological underpinnings of alcohol dependence. We propose that unlike previously available pharmacotherapies, acamprosate represents a prototype of a neuromodulatory approach in the treatment of alcohol dependence. A neuromodulatory approach seeks to restore the disrupted changes in neurobiology resulting from chronic alcohol intake. It is our opinion that a neuromodulatory approach will provide a heuristic framework for developing more effective pharmacotherapies for alcohol dependence. PMID:20201812

This study examined the influences of parental divorce and maternal-paternal histories of alcohol problems on adult offspring lifetime alcohol dependence using data from the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC). Parental divorce and maternal-paternal alcohol problems interacted to differentially influence the likelihood of offspring lifetime alcohol dependence. Experiencing parental divorce and either maternal or paternal alcohol problems doubled the likelihood of alcohol dependence. Divorce and history of alcohol problems for both parents tripled the likelihood. Offspring of parental divorce may be more vulnerable to developing alcohol dependence, particularly when one or both parents have alcohol problems.

The objective of this study is to examine the effect of fetal alcohol exposure on later substance dependence using an adoption study method. One hundred ninety-seven adoptees were interviewed for substance abuse disorders, including nicotine, alcohol, and drug dependence. Twenty-one adoptees had mothers who drank during pregnancy. Adoptees with fetal alcohol exposure were compared with those without fetal alcohol exposure for symptoms of adult nicotine, alcohol, and drug dependence. Adoptee symptom counts for alcohol, drug, and nicotine dependence were higher for those exposed to alcohol in utero. The effect of fetal alcohol exposure remained after controlling for gender, biological parent alcohol dependence diagnosis, birth weight, gestational age and other environmental variables. Fetal alcohol exposure may produce increased risk for later nicotine, alcohol, and drug dependence. Possible effects of fetal alcohol exposure on development of adult substance use patterns needs attention in genetic studies of substance abuse.
Current hypotheses on the mechanisms of alcoholism.
Vetreno, R P; Crews, F T
2014-01-01
Chronic use of alcohol results in progressive changes to brain and behavior that often lead to the development of alcohol dependence and alcoholism. Although the mechanisms underlying the development of alcoholism remain to be fully elucidated, diminished executive functioning due to hypoactive prefrontal cortex executive control and hyperactive limbic system anxiety and negative emotion might contribute mechanistically to the shift from experimental use to alcoholism and dependence. In the chapter that follows, behavioral deficits associated with cortical dysfunction and neurodegeneration will be related to the behavioral characteristics of alcoholism (e.g., diminished executive function, impulsivity, altered limbic modulation). We will provide evidence that alterations in cyclic AMP-responsive element binding protein (CREB: neurotrophic) and NF-κB (neuroimmune) signaling contribute to the development and persistence of alcoholism. In addition, genetic predispositions and an earlier age of drinking onset will be discussed as contributing factors to the development of alcohol dependence and alcoholism. Overall chronic ethanol-induced neuroimmune gene induction is proposed to alter limbic and frontal neuronal networks contributing to the development and persistence of alcoholism. © 2014 Elsevier B.V.

The aims of this study were to develop a bilingual version of the Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA) in English and Samoan and determine the reliability of assessments of alcohol dependence in American Samoa. The study consisted of development and reliability-testing phases. In the development phase, the SSADDA alcohol module was translated and the translation was evaluated through cognitive interviews. In the reliability-testing phase, the bilingual SSADDA was administered to 40 ethnic Samoans, including a sub-sample of 26 individuals who were retested. Cognitive interviews indicated the initial translation was culturally and linguistically appropriate except items pertaining to alcohol tolerance, which were modified to reflect Samoan concepts. SSADDA reliability testing indicated diagnoses of DSM-III-R and DSM-IV alcohol dependence were reliable. Reliability varied by language of administration. The English/Samoan version of the SSADDA is appropriate for the diagnosis of DSM-III-R alcohol dependence, which may be useful in advancing research and public health efforts to address alcohol problems in American Samoa and the Western Pacific. The translation methods may inform researchers translating diagnostic and assessment tools into different languages and cultures. © The Author 2014.

Herein, we have reviewed the role of glutamate, the major excitatory neurotransmitter in the brain, in a number of neurochemical, -physiological, and -behavioral processes mediating the development of alcohol dependence. The findings discussed include results from both preclinical as well as neuroimaging and postmortem clinical studies. Expression levels for a number of glutamate-associated genes and/or proteins are modulated by alcohol abuse and dependence. These changes in expression include metabotropic receptors and ionotropic receptor subunits as well as different glutamate transporters. Moreover, these changes in gene expression parallel the pharmacologic manipulation of these same receptors and transporters. Some of these gene expression changes may have predated alcohol abuse and dependence because a number of glutamate-associated polymorphisms are related to a genetic predisposition to develop alcohol dependence. Other glutamate-associated polymorphisms are linked to age at the onset of alcohol-dependence and initial level of response/sensitivity to alcohol. Finally, findings of innate and/or ethanol-induced glutamate-associated gene expression differences/changes observed in a genetic animal model of alcoholism, the P rat, are summarized. Overall, the existing literature indicates that changes in glutamate receptors, transporters, enzymes, and scaffolding proteins are crucial for the development of alcohol dependence and there is a substantial genetic component to these effects. This indicates that continued research into the genetic underpinnings of these glutamate-associated effects will provide important novel molecular targets for treating alcohol abuse and dependence.

The purpose of this review paper is to present evidence that rat animal models of alcoholism provide an ideal platform for developing and screening medications that target alcohol abuse and dependence. The focus is on the 5 oldest international rat lines that have been selectively bred for a high alcohol-consumption phenotype. The behavioral and neurochemical phenotypes of these rat lines are reviewed and placed in the context of the clinical literature. The paper presents behavioral models for assessing the efficacy of pharmaceuticals for the treatment of alcohol abuse and dependence in rodents, with particular emphasis on rats. Drugs that have been tested for their effectiveness in reducing alcohol/ethanol consumption and/or self-administration by these rat lines and their putative site of action are summarized. The paper also presents some current and future directions for developing pharmacological treatments targeting alcohol abuse and dependence. PMID:22841890
[Creation of a scale for evaluating attitudes of partners toward alcohol dependency].

The aim of this study was to develop a scale to evaluate characteristics of how alcohol-dependent people perceive the attitudes of their partners toward alcohol dependency. Based on previous research, we created the "Attitudes of partners toward alcohol dependency" scale, from the perspective of the alcohol dependent individual. Using the new scale, 71 alcohol-dependent people (52 men, 19 women) were surveyed after obtaining their consent, and the reliability and validity of the scale were tested. The results identified 3 factors, "indifference", "acceptance" and "hypersensitivity", and factorial validity was verified. Relatively high reliability was obtained on each sub-scale (alpha = .60-.82). Furthermore, correlations were obtained with the alcohol-dependency "Denial and Awareness Scale (for alcohol-dependent people)" and with the 13-item "Usefulness of heterosexual love relations for recovery from alcohol dependency" questionnaire, which includes content on "beneficial" or "obstructive" to recovery, and with the satisfaction and the importance of relations. This demonstrates that the "Attitudes of partners toward alcohol dependency" scale has reliability and criterion-related validity. The scale facilitates evaluation of types of attitudes of partners toward alcohol dependency, and may thus be useful as one tool for investigating the influence of partners in heterosexual love relationships for recovery, and for providing advice.

Both a family history of alcoholism and migration-related factors like US v. foreign nativity increase the risk for developing alcohol use disorders in Hispanic Americans. For this study, we integrated these two lines of research to test whether the relationship between familial alcoholism and alcohol dependence changes with successive generations in the United States. Data were from the waves 1 and 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Subjects self-identified Hispanic ethnicity (N = 4122; n = 1784 first, n = 1169 second, and n = 1169 third or later generation) and reported ever consuming ⩾12 drinks in a 1-year period. A family history of alcoholism was assessed in first- and second-degree relatives. Analyses predicting the number of alcohol dependence symptoms were path models. Alcohol dependence symptoms were associated with a stronger family history of alcoholism and later generational status. There was a significant interaction effect between familial alcoholism and generational status; the relationship of familial alcoholism with alcohol dependence symptoms increased significantly with successive generations in the United States, more strongly in women than men. Acculturation partially mediated the interaction effect between familial alcoholism and generational status on alcohol dependence, although not in the expected direction. Familial alcoholism interacted with generational status in predicting alcohol dependence symptoms in US Hispanic drinkers. This relationship suggests that heritability for alcoholism is influenced by a higher-order environmental factor, likely characterized by a relaxing of social restrictions on drinking.

Estimates of the prevalence of alcohol dependence among Americans approach 14% (Read, Kahler, & Stevenson, 2001). Alcohol dependence was once considered among the most recalcitrant of problem behaviors, with only 20% to 30% attaining sustained abstinence (Hunt Barnett & Branch 1971). Although current definitions of treatment success now consider…
Impulsivity Moderates Subjective Responses to Alcohol in Alcohol-Dependent Individuals.
Westman, Jonathan G; Bujarski, Spencer; Ray, Lara A
2017-03-09
Studies of social drinkers indicate that subjective response (SR) to alcohol and impulsivity are risk factors for the development of alcohol use disorder which may be related. It is unclear, however, whether there are significant relationships between SR and impulsivity among individuals with alcohol dependence. Using data from an intravenous (IV) alcohol challenge study, the present study is the first to explore the relationship between impulsivity and SR during alcohol administration among alcohol-dependent individuals. Non-treatment-seeking, alcohol-dependent individuals (N = 42) completed the Delay Discounting Task to measure impulsivity and then completed two counterbalanced, placebo-controlled IV alcohol administration sessions, which included assessments of SR at breath alcohol concentration (BrAC) levels of 0.00, 0.02, 0.04 and 0.06 g/dl. Analyses revealed that more impulsive participants experienced higher subjective stimulation and positive mood in response to rising BrACs as compared to less impulsive individuals. More impulsive participants also experienced increased sedation over time regardless of condition (i.e. alcohol vs. saline). These findings suggest that among alcohol-dependent individuals, impulsivity is positively associated with the hedonic effects of alcohol as compared to placebo. High impulsivity may characterize a subset of alcohol-dependent individuals who drink to experience the rewarding effects of alcohol. © The Author 2016.

Background The associations between depressive symptoms and alcohol-related disorders, drinking patterns and other characteristics of alcohol use are important public health issues worldwide. This study aims to study these associations in an upper middle-income country, Brazil, and search for related socio-demographic correlations in men and women. Methods A cross-sectional study was conducted between November 2005 and April 2006. The sample of 3,007 participants, selected using a multistage probabilistic sampling method, represents the Brazilian population aged 14 and older. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale and alcohol dependence was assessed using the Composite International Diagnostic Interview. Associations assessed using bi-variate analysis were tested using Rao-Scott measures. Gender specific multinomial logistic regression models were developed. Results Among the participants with alcohol dependence, 46% had depressive symptoms (17.2% mild/moderate and 28.8% major/severe; p < 0.01); 35.8% (p = 0.08) of those with alcohol abuse and 23.9% (p < 0.01) of those with a binge-drinking pattern also had depressive symptoms. Alcohol abstainers and infrequent drinkers had the highest prevalence of major/severe depressive symptoms, whereas frequent heavy drinkers had the lowest prevalence of major/severe depressive symptoms. In women, alcohol dependence and the presence of one or more problems related to alcohol consumption were associated with higher risks of major/severe depressive symptoms. Among men, alcohol dependence and being ≥45 years old were associated with higher risks of major/severe depressive symptoms. Conclusions In Brazil, the prevalence of depressive symptoms is strongly related to alcohol dependence; the strongest association was between major/severe depressive symptoms and alcohol dependence in women. This survey supports the possible association of biopsychosocial distress, alcohol consumption and the prevalence of depressive symptoms in Brazil. Investing in education, social programs, and care for those with alcohol dependence and major/severe depressive symptoms, especially for such women, and the development of alcohol prevention policies may be components of a strategic plan to reduce the prevalence of depression and alcohol problems in Brazil. Such a plan may also promote the socio-economic development of Brazil and other middle-income countries. PMID:25027830
Gender differences in the effects of ADH1B and ALDH2 polymorphisms on alcoholism.

Gender differences are known to exist in the prevalence, characteristics, and course of alcohol dependence. Elucidating gender differences in the characteristics of alcohol dependence is important in gender-based medicine and may improve treatment outcomes. Many studies have shown that genetic factors are associated with the risk of alcohol dependence in both genders. Polymorphisms of alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) are strong genetic determinants of alcohol dependence. This study aimed to clarify gender differences in the effects of ADH1B and ALDH2 polymorphism on the development of alcohol dependence. Subjects were 200 female alcoholics and 415 male alcoholics hospitalized in Kurihama Alcoholism Center. Clinical information and background data were obtained by chart review. ALDH2 and ADH1B genotyping was performed by the polymerase chain reaction-restriction fragment length polymorphism method. The onset age of female alcoholics with inactive ALDH2 genotype was significantly lower than those with active ALDH2 genotype, but the onset age did not differ between the inactive and active ALDH2 group in male alcoholics. The difference in onset age between the ADH1B genotype groups did not reach significant levels. The prevalence of comorbid psychiatric disorders, including major depression, eating disorder, panic disorder, and borderline personality disorder, was significantly higher in female alcoholics with inactive ALDH2 or superactive ADH1B than in those with active ALDH2 or normal ADH1B. ALDH2 polymorphism appears to have contrasting effects on the development of alcoholism in women and men. One possible reason for this gender difference may be the high prevalence of psychiatric comorbidities in female alcoholics with inactive ALDH2.

Mounting evidence over the last 40 years clearly indicates that alcoholism (alcohol dependence) is a disorder of the brain. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) has taken significant steps to advance research into the neuroscience of alcohol. The Division of Neuroscience and Behavior (DNB) was formed within NIAAA in 2002 to oversee, fund, and direct all research areas that examine the effects of alcohol on the brain, the genetic underpinnings of alcohol dependence, the neuroadaptations resulting from excessive alcohol consumption, advanced behavioral models of the various stages of the addiction cycle, and preclinical medications development. This research portfolio has produced important discoveries in the etiology, treatment, and prevention of alcohol abuse and dependence. Several of these salient discoveries are highlighted and future areas of neuroscience research on alcohol are presented. © 2014 Elsevier B.V. All rights reserved.

In the following study we tested the stress response dampening (SRD) model which postulates that stress responses are more likely to be attenuated by alcohol in individuals at risk for alcohol dependence than in persons without that risk. In a laboratory experiment we examined a) if SRD effects exist for both sons and healthy daughters of alcohol dependent fathers, and b) if SRD effects exist for siblings of alcohol dependent males. We recruited 104 subjects at risk and 51 matched control subjects. In a laboratory experiment, study subjects received alcohol in one of two laboratory sessions and a stress paradigm served to elicit heart rate stress responses. Heart rate stress responses were attenuated by alcohol in female family history positive (FHP) and female family history negative (FHN) subjects, however not in males. A multiple regression analysis revealed "Heart Rate Stress Response in the Non-Alcohol Condition" and "Blood Alcohol Level" as significant predictors of SRD. According to our findings, females carry a distinct risk for developing alcohol dependence, regardless of their family history and regardless of their degree of familial relationship. This is an important issue for devising models concerning the development and maintenance of alcohol dependence in females. The study extends the current research literature, which mainly focuses on male subjects at risk, by including female subjects at risk, as well as siblings at risk of both genders.

Alcohol use is commonly reported as a short-term criminal risk factor; however there is minimal research on the effects of alcohol dependence on crime. Canadian Aboriginal offenders exhibit both disproportionate crime and alcohol disorder prevalence. This study aims to examine the impact of diagnosed alcohol dependence on Aboriginal ethnicity and criminal sentencing in British Columbia. We used an administrative linkage database of social, health and justice system variables to develop a retrospective cohort of 70,035 offenders sentenced through courts in British Columbia from 2001-2010. We used a coefficient difference mediation analysis to evaluate the mediating effect of alcohol dependence on the association between self-reported Aboriginal status and sentencing rate. Aboriginal offenders had 1.92 (95% C.I.: 1.79,2.06) times higher odds of alcohol dependence than Caucasian offenders. Adjustment for health, social and demographic factors resulted in a 27% (95% Confidence Interval (CI): 15%, 33%) reduction in the association of Aboriginal ethnicity on sentencing. Adjustment for alcohol dependence resulted in only a further reduction of 2% (95% CI: -12%, 15%). Although alcohol dependence was associated both with Aboriginal ethnicity and sentencing, it did not have a significant mediating impact on sentencing rate. Alcohol dependence was not a mediator for the relationship between sentencing rate and Aboriginal ethnicity. However, due to the proportion of offenders diagnosed with alcohol dependence, these results support alcohol misuse as an important public health policy target in this population.

Alcohol-Induced Blackouts and Other Negative Outcomes During the Transition Out of College
Wilhite, Emily R.; Fromme, Kim

Objective: There is considerable debate about the prospective association between alcohol-dependence symptoms and alcohol-related blackouts. The goal of this study was to examine the associations among alcohol-dependence symptoms, blackouts, and social and emotional consequences during the transition out of college. Method: Participants (N = 829; 66% female) were part of a 6-year longitudinal study designed to explore alcohol use and risky behaviors during and after college. Data for these analyses were from Years 4 and 5 of data collection, which most closely corresponded to the transition out of college. Using cross-lagged models, we tested the prospective associations of alcohol-dependence symptoms, blackout frequency, and social and emotional consequences. Results: Alcohol-dependence symptoms in Year 4 predicted increased frequency of blackouts and social and emotional consequences during the subsequent year. Blackouts during Year 4 also significantly predicted increased alcohol-related social and emotional consequences, but not dependence symptoms, in Year 5. Conclusions: Although blackouts do not predict the development of alcohol-dependence symptoms, they increase the risk for less severe alcohol-related consequences during the transition out of college. This may result from the cognitive reconciliation of negative behaviors that occur during these episodes of amnesia. PMID:26098026

Abusive alcohol use has well-established health risks including causing liver disease (ALD) characterized by alcoholic steatosis (AS), steatohepatitis (AH), fibrosis, cirrhosis (AC) and hepatocellular carcinoma (HCC). Strikingly, a significant number of individuals who abuse alcohol also use Cannabis, which has seen increased legalization globally. While cannabis has demonstrated anti-inflammatory properties, its combined use with alcohol and the development of liver disease remain unclear. The aim of this study was to determine the effects of cannabis use on the incidence of liver disease in individuals who abuse alcohol. We analysed the 2014 Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (NIS) discharge records of patients 18 years and older, who had a past or current history of abusive alcohol use (n = 319 514). Using the International Classification of Disease, Ninth Edition codes, we studied the four distinct phases of progressive ALD with respect to three cannabis exposure groups: non-cannabis users (90.39%), non-dependent cannabis users (8.26%) and dependent cannabis users (1.36%). We accounted for the complex survey sampling methodology and estimated the adjusted odds ratio (AOR) for developing AS, AH, AC and HCC with respect to cannabis use (SAS 9.4). Our study revealed that among alcohol users, individuals who additionally use cannabis (dependent and non-dependent cannabis use) showed significantly lower odds of developing AS, AH, AC and HCC (AOR: 0.55 [0.48-0.64], 0.57 [0.53-0.61], 0.45 [0.43-0.48] and 0.62 [0.51-0.76]). Furthermore, dependent users had significantly lower odds than non-dependent users for developing liver disease. Our findings suggest that cannabis use is associated with a reduced incidence of liver disease in alcoholics. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Abstinence from alcohol is associated with the recruitment of neurons in the central nucleus of the amygdala (CeA) in nondependent rats that binge drink alcohol and in alcohol-dependent rats. However, whether the recruitment of this neuronal ensemble in the CeA is causally related to excessive alcohol drinking or if it represents a consequence of excessive drinking remains unknown. We tested the hypothesis that the recruitment of a neuronal ensemble in the CeA during abstinence is required for excessive alcohol drinking in nondependent rats that binge drink alcohol and in alcohol-dependent rats. We found that inactivation of the CeA neuronal ensemble during abstinence significantly decreased alcohol drinking in both groups. In nondependent rats, the decrease in alcohol intake was transient and returned to normal the day after the injection. In dependent rats, inactivation of the neuronal ensemble with Daun02 produced a long-term decrease in alcohol drinking. Moreover, we observed a significant reduction of somatic withdrawal signs in dependent animals that were injected with Daun02 in the CeA. These results indicate that the recruitment of a neuronal ensemble in the CeA during abstinence from alcohol is causally related to excessive alcohol drinking in alcohol-dependent rats, whereas a similar neuronal ensemble only partially contributed to alcohol-binge-like drinking in nondependent rats. These results identify a critical neurobiological mechanism that may be required for the transition to alcohol dependence, suggesting that focusing on the neuronal ensemble in the CeA may lead to a better understanding of the etiology of alcohol use disorders and improve medication development. Alcohol dependence recruits neurons in the central nucleus of the amygdala (CeA). Here, we found that inactivation of a specific dependence-induced neuronal ensemble in the CeA reversed excessive alcohol drinking and somatic signs of alcohol dependence in rats. These results identify a critical neurobiological mechanism that is required for alcohol dependence, suggesting that targeting dependence neuronal ensembles may lead to a better understanding of the etiology of alcohol use disorders, with implications for diagnosis, prevention, and treatment.

The concern that alcohol advertising can have detrimental effects on vulnerable viewers has prompted the development of codes of responsible advertising practices. This paper evaluates critically the concept of vulnerability as it applies to (1) susceptibility to alcohol-related harm and (2) susceptibility to the effects of marketing, and describes its implications for the regulation of alcohol marketing. We describe the findings of key published studies, review papers and expert reports to determine whether these two types of vulnerability apply to population groups defined by (1) age and developmental history; (2) personality characteristics; (3) family history of alcoholism; (4) female sex and pregnancy risk; and (5) history of alcohol dependence and recovery status. Developmental theory and research suggest that groups defined by younger age, incomplete neurocognitive development and a history of alcohol dependence may be particularly vulnerable because of the disproportionate harm they experience from alcohol and their increased susceptibility to alcohol marketing. Children may be more susceptible to media imagery because they do not have the ability to compensate for biases in advertising portrayals and glamorized media imagery. Young people and people with a history of alcohol dependence appear to be especially vulnerable to alcohol marketing, warranting the development of new content and exposure guidelines focused on protecting those groups to improve current self-regulation codes promoted by the alcohol industry. If adequate protections cannot be implemented through this mechanism, statutory regulations should be considered. © 2016 Society for the Study of Addiction.

It has previously been shown that the inhibition of L-type calcium channels (LTCCs) decreases alcohol consumption, although the contribution of the central LTCC subtypes Cav1.2 and Cav1.3 remains unknown. Here, we determined changes in Cav1.2 (Cacna1c) and Cav1.3 (Cacna1d) mRNA and protein expression in alcohol-dependent rats during protracted abstinence and naive controls using in situ hybridization and western blot analysis. Functional validation was obtained by electrophysiological recordings of calcium currents in dissociated hippocampal pyramidal neurons. We then measured alcohol self-administration and cue-induced reinstatement of alcohol seeking in dependent and nondependent rats after intracerebroventricular (i.c.v.) injection of the LTCC antagonist verapamil, as well as in mice with an inducible knockout (KO) of Cav1.2 in Ca2+/calmodulin-dependent protein kinase IIα (CaMKIIα)-expressing neurons. Our results show that Cacna1c mRNA concentration was increased in the amygdala and hippocampus of alcohol-dependent rats after 21 days of abstinence, with no changes in Cacna1d mRNA. This was associated with increased Cav1.2 protein concentration and L-type calcium current amplitudes. Further analysis of Cacna1c mRNA in the CA1, basolateral amygdala (BLA), and central amygdala (CeA) revealed a dynamic regulation over time during the development of alcohol dependence. The inhibition of central LTCCs via i.c.v. administration of verapamil prevented cue-induced reinstatement of alcohol seeking in alcohol-dependent rats. Further studies in conditional Cav1.2-KO mice showed a lack of dependence-induced increase of alcohol-seeking behavior. Together, our data indicate that central Cav1.2 channels, rather than Cav1.3, mediate alcohol-seeking behavior. This finding may be of interest for the development of new antirelapse medications.

Prenatal exposures to alcohol, cigarettes, and other drugs of abuse are associated with numerous adverse consequences for affected offspring, including increased risk for substance use and abuse. However, maternal substance use during pregnancy appears to occur more often in those with a family history of alcohol dependence. Utilizing a sample that is enriched for familial alcohol dependence and includes controls selected for virtual absence of familial alcohol dependence could provide important information on the relative contribution of familial risk and prenatal exposures to offspring substance use. A sample of multigenerational families specifically ascertained to be at either high or low risk for developing alcohol dependence (AD) provided biological offspring for a longitudinal prospective study. High-risk families were selected based on the presence of 2 alcohol-dependent sisters. Low-risk families were selected on the basis of minimal first and second-degree relatives with AD. High-risk (HR = 99) and Low-risk offspring (LR = 110) were assessed annually during childhood and biennially in young adulthood regarding their alcohol, drug, and cigarette use. At the first childhood visit, mothers were interviewed concerning their prenatal use of substances. High-risk mothers were more likely to use alcohol, cigarettes, and other drugs during pregnancy than low-risk control mothers, and to consume these substances in greater quantities. Across the sample, prenatal exposure to alcohol was associated with increased risk for both offspring cigarette use and substance use disorders (SUD), and prenatal cigarette exposure was associated with increased risk for offspring cigarette use. Controlling for risk status by examining patterns within the HR sample, prenatal cigarette exposure remained a specific predictor of offspring cigarette use, and prenatal alcohol exposure was specifically associated with increased risk for offspring SUD. Women with a family history of SUD are at increased risk for substance use during pregnancy. Both familial loading for alcohol dependence and prenatal exposure to alcohol or cigarettes are important risk factors in the development of offspring substance use. An inadequate assessment of family history may obscure important interactions between familial risk and prenatal exposures on offspring outcomes.

We investigated the differential influence of family dysfunction on alcohol and methamphetamine dependence in Japan using the Addiction Severity Index (ASI), a useful instrument that multilaterally measures the severity of substance dependence. The participants in this study were 321 male patients with alcohol dependence and 68 male patients with methamphetamine dependence. We conducted semi-structured interviews with each patient using the ASI, which is designed to assess problem severity in seven functional domains: Medical, Employment/Support, Alcohol use, Drug use, Legal, Family/Social relationships, and Psychiatric. In patients with alcohol dependence, bad relationships with parents, brothers and sisters, and friends in their lives were related to current severe psychiatric problems. Bad relationships with brothers and sisters and partners in their lives were related to current severe employment/support problems, and bad relationships with partners in their lives were related to current severe family/social problems. The current severity of psychiatric problems was related to the current severity of drug use and family/social problems in patients with alcohol dependence. Patients with methamphetamine dependence had difficulty developing good relationships with their father. Furthermore, the current severity of psychiatric problems was related to the current severity of medical, employment/support, and family/social problems in patients with methamphetamine dependence. The results of this study suggest that family dysfunction differentially affects alcohol and methamphetamine dependence. Additionally, family relationships may be particularly related to psychiatric problems in these patients, although the ASI was developed to independently evaluate each of seven problem areas.

Applicability of Type A/B alcohol dependence in the general population.
Tam, Tammy W; Mulia, Nina; Schmidt, Laura A
2014-05-01
This study examined the concurrent and predictive validity of Type A/B alcohol dependence in the general population-a typology developed in clinical populations to gauge severity of dependence. Data were drawn from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The sample included 1,172 alcohol-dependent drinkers at baseline who were reinterviewed three years later. Latent class analysis was used to derive Type A/B classification using variables replicating the original Type A/B typology. Predictive validity of the Type A/B classification was assessed by multivariable linear and logistic regressions. A two-class solution consistent with Babor's original Type A/B typology adequately fit the data. Type B alcoholics in the general population, compared to Type As, had higher alcohol severity and more co-occurring drug, mental, and physical health problems. In the absence of treatment services utilization, Type B drinkers had two times the odds of being alcohol dependent three years later. Among those who utilized alcohol treatment services, Type B membership was predictive of heavy drinking and drug dependence, but not alcohol dependence, three years later. Findings suggest that Type A/B classification is both generalizable to, and valid within, the US general population of alcohol dependent drinkers. Results highlight the value of treatment for mitigating the persistence of dependence among Type B alcoholics in the general population. Screening for markers of vulnerability to Type B dependence could be of clinical value for health care providers to determine appropriate intervention. Copyright © 2014 Elsevier Ireland Ltd.

DEVELOPMENT OF MOTIVATION SCALE - CLINICAL VALIDATION WITH ALCOHOL DEPENDENTS
Neeliyara, Teresa; Nagalakshmi, S.V.
1994-01-01
This study focusses on the development of a comprehensive multi-dimensional scale for assessing motivation for change in the alcohol dependent population. After establishing face validity, the items evolved were administered to a normal sample of 600 male subjects in whom psychiatric illness was ruled out. The data thus obtained was subjected to factor analysis. Six factors were obtained which accounted for 55.2% of variance. These together formed a 80 item five point scale and norms were established on a sample of 600 normal subjects. Further clinical validation was established on 30 alcohol dependent subjects and 30 normals. The status of motivation was found to be inadequate in alcohol dependent individuals as compared to the normals. Split-half reliability was carried out and the tool was found to be highly reliable.

Glutamatergic plasticity and alcohol dependence-induced alterations in reward, affect and cognition.
Burnett, Elizabeth J; Chandler, L Judson; Trantham-Davidson, Heather
2016-02-04
Alcohol dependence is characterized by a reduction in reward threshold, development of a negative affective state, and significant cognitive impairments. Dependence-induced glutamatergic neuroadaptations in the neurocircuitry mediating reward, affect and cognitive function are thought to underlie the neural mechanism for these alterations. These changes serve to promote increased craving for alcohol and facilitate the development of maladaptive behaviors that promote relapse to alcohol drinking during periods of abstinence. To review the extant literature on the effects of chronic alcohol exposure on glutamatergic neurotransmission and its impact on reward, affect and cognition. Evidence from a diverse set of studies demonstrates significant enhancement of glutamatergic activity following chronic alcohol exposure. In particular, up-regulation of GluN2B-containing NMDA receptor expression and function is a commonly observed phenomenon that likely reflects activity-dependent adaptive homeostatic plasticity. However, this observation as well as other glutamatergic neuroadaptations are often circuit and cell-type specific. Dependence-induced alterations in glutamate signaling contribute to many of the symptoms experienced in addicted individuals and can persist well into abstinence. This suggests that they play an important role in the development of behaviors that increase the probability for relapse. As our understanding of the complexity of the neurocircuitry involved in the addictive process has advanced, it has become increasingly clear that investigations of cell-type and circuit-specific effects are required to gain a more comprehensive understanding of the glutamatergic adaptations and their functional consequences in alcohol addiction. While pharmacological treatments for alcohol dependence and relapse targeting the glutamatergic system have shown great promise in preclinical models, more research is needed to uncover novel, possibly circuit-specific, therapeutic targets that exhibit improved efficacy and reduced side effects.

Alcohol dependence/addiction is mediated by complex neural mechanisms that involve multiple brain circuits and neuroadaptive changes in a variety of neurotransmitter and neuropeptide systems. Although recent studies have provided substantial information on the neurobiological mechanisms that drive alcohol drinking behavior, significant challenges remain in understanding how alcohol-induced neuroadaptations occur and how different neurocircuits and pathways cross-talk. This review article highlights recent progress in understanding neural mechanisms of alcohol addiction from the perspectives of the development and maintenance of alcohol dependence. It provides insights on cross talks of different mechanisms and reviews the latest studies on metaplasticity, structural plasticity, interface of reward and stress pathways, and cross-talk of different neural signaling systems involved in binge-like drinking and alcohol dependence.

Cognitive processing of drug-related stimuli: the role of memory and attention.
Weinstein, Aviv; Cox, W Miles
2006-11-01
Recent studies have investigated the role of attentional biases and memory in alcohol and other drugs of dependence and the relationship between the motivation to use alcohol or other drugs and vigilance for relevant stimuli in alcohol and drug dependence. Based on this research, we describe relationships among motivation, memory, and attentional biases in order to enable better understanding of their multiple and interacting roles in the maintenance and development of alcohol and other drug dependence. We argue that memory and attentional processes are critical in the development and maintenance of addiction processes. Furthermore, we assume that attentional bias is not simply a by-product of an addiction disorder but plays a vital role in its development and maintenance, and it serves to enhance actual drug use. Finally, we predict that the motivation to use alcohol or other drugs will increase vigilance for substance-related stimuli, which in turn can lead to actual use. Future research is needed to ll gaps in our knowledge and lead to a more defined and articulated cognitive-behavioural model of drug dependence.
Alcoholism risk moderation by a socio-religious dimension.
Haber, Jon Randolph; Jacob, Theodore
2007-11-01
Religious affiliation is inversely associated with the development of alcohol-dependence symptoms in adolescents, but the mechanisms of this effect are unclear. The degree to which religious affiliations accommodate to or differentiate from cultural values may influence attitudes about alcohol use. We hypothesized that, given permissive cultural norms about alcohol in the United States, if a religious affiliation differentiates itself from cultural norms, then high-risk adolescents (those with parents having a history of alcoholism) would exhibit fewer alcohol-dependence symptoms compared with other affiliations and nonreligious adolescents. A sample of female adolescent offspring (N = 3,582) in Missouri was selected. Parental alcoholism and religious affiliation and their interaction were examined as predictors of offspring alcohol-dependence symptoms. Findings indicated that (1) parental alcohol history robustly predicted increased offspring alcohol-dependence symptoms, (2) religious rearing appeared protective (offspring exhibited fewer alcohol-dependence symptoms), (3) religious differentiation accounted for most of the protective effect, (4) other religious variables did not account for the differentiation effect, and (5) black religious adolescents were more frequently raised with differentiating affiliations and exhibited greater protective effects. Results demonstrate that religious differentiation accounts for most of the protective influence of religious affiliation. This may be because religious differences from cultural norms (that include permissive alcohol norms) counteract these social influences given alternative "higher" religious ideals.
Combined alcohol and energy drink use: hedonistic motives, adenosine, and alcohol dependence.
Marczinski, Cecile A
2014-07-01
Consumption of alcohol mixed with energy drinks (AmED) has been associated with both short- and long-term risks beyond those observed with alcohol alone. AmED use has been associated with heavy episodic (binge) drinking, risky behaviors, and risk of alcohol dependence. Laboratory research has demonstrated that AmED beverages lead to greater motivation to drink versus the same amount of alcohol consumed alone. However, the reason consumers find AmED beverages particularly appealing has been unclear. A recent report by Droste and colleagues (Alcohol Clin Exp Res 2014; 38:2087-2095) is the first study to investigate motivations related to AmED consumption and to determine which motives predict AmED consumption patterns, experience of drinking-related harms, and risk of alcohol dependence. The findings of this study significantly enhance our understanding of why AmED consumption is related to the risk of alcohol dependence and change our understanding of why consumers choose AmED beverages. The authors report that hedonistic motives strongly predicted AmED use and the harms associated with use. While intoxication-reduction motives predicted self-reported accidents and injuries, these motives did not predict AmED consumption patterns and risk of dependence. The risk of alcohol dependence may arise from repeated experiences when drinking alcohol is more pleasurable when energy drinks are consumed with the alcohol. This commentary will focus on why energy drinks might increase the rewarding properties of alcohol in social drinkers. In addition, discussion is provided explaining why more research on the neurotransmitter, adenosine, may actually inform us about the mechanisms contributing to the development of alcohol dependence.

Alcohol is the most consumed substance among young people, and the onset of its use is starting at an earlier age, raising the risks of future dependence. The use of alcohol in adolescence is associated with a series of risk behaviors, besides raising the risk of involvement in accidents, sexual violence, and participating in gangs. Alcohol use by adolescents is strongly associated with violent death, poor academic performance, learning difficulties and damage in the development and structuring of cognitive-behavioral and emotional abilities. Alcohol consumption causes neurochemical modifications, with damage in memory, learning and impulse control. Professionals who deal with adolescents must be prepared for a thorough evaluation regarding the possible abusive use or dependence of alcohol in this age group. However, it is important to emphasize that the criteria utilized by some diagnostic tools for abuse and dependence were developed for adults, and must be applied with caution in adolescents. Thus, it is fundamental that these professionals be aware of the characteristics and peculiarities of adolescence and chemical dependence in this age-group.

Emotional and interpersonal impairments have been largely reported in alcohol-dependence, and their role in its development and maintenance is widely established. However, earlier studies have exclusively focused on group comparisons between healthy controls and alcohol-dependent individuals, considering them as a homogeneous population. The variability of socio-emotional profiles in this disorder thus remains totally unexplored. The present study used a cluster analytic approach to explore the heterogeneity of affective and social disorders in alcohol-dependent individuals. 296 recently-detoxified alcohol-dependent patients were first compared with 246 matched healthy controls regarding self-reported emotional (i.e. alexithymia) and social (i.e. interpersonal problems) difficulties. Then, a cluster analysis was performed, focusing on the alcohol-dependent sample, to explore the presence of differential patterns of socio-emotional deficits and their links with demographic, psychopathological and alcohol-related variables. The group comparison between alcohol-dependent individuals and controls clearly confirmed that emotional and interpersonal difficulties constitute a key factor in alcohol-dependence. However, the cluster analysis identified five subgroups of alcohol-dependent individuals, presenting distinct combinations of alexithymia and interpersonal problems ranging from a total absence of reported impairment to generalized socio-emotional difficulties. Alcohol-dependent individuals should no more be considered as constituting a unitary group regarding their affective and interpersonal difficulties, but rather as a population encompassing a wide variety of socio-emotional profiles. Future experimental studies on emotional and social variables should thus go beyond mere group comparisons to explore this heterogeneity, and prevention programs proposing an individualized evaluation and rehabilitation of these deficits should be promoted.

FRONTO-STRIATAL FUNCTIONAL CONNECTIVITY DURING RESPONSE INHIBITION IN ALCOHOL DEPENDENCE
Courtney, Kelly E.; Ghahremani, Dara G.; Ray, Lara A.
2013-01-01
Poor response inhibition has been implicated in the development of alcohol dependence, yet little is known about how neural pathways underlying cognitive control are affected in this disorder. Moreover, endogenous opioid levels may impact the functionality of inhibitory control pathways. This study investigated the relationship between alcohol dependence severity and functional connectivity of fronto-striatal networks during response inhibition in an alcohol dependent sample. A secondary aim of this study was to test the moderating effect of a functional polymorphism (A118G) of the µ-opioid receptor (OPRM1) gene. Twenty individuals with alcohol dependence (6 females; 90% Caucasian; mean age = 29.4) who were prospectively genotyped on the OPRM1 gene underwent blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) while performing a Stop Signal Task (SST). The relationship between alcohol dependence severity and functional connectivity within fronto-striatal networks important for response inhibition was assessed using psychophysiological interaction (PPI) analyses. Analyses revealed greater alcohol dependence severity associated with weaker functional connectivity between the putamen and prefrontal regions (e.g., the anterior insula, anterior cingulate, and medial prefrontal cortex) during response inhibition. Further, the OPRM1 genotype was associated with differential response inhibition-related functional connectivity. This study demonstrates that individuals with more severe alcohol dependence exhibit less frontal connectivity with the striatum, a component of cognitive control networks important for response inhibition. These findings suggest that the fronto-striatal pathway underlying response inhibition is weakened as alcoholism progresses. PMID:23240858

Background A low level of response to alcohol is a major risk factor for the development of alcohol dependence, but neural correlates of this marker are unclear. Method Ten healthy volunteers were classified by median split on level of response to alcohol and underwent 2 sessions of functional magnetic resonance imaging following ingestion of a moderate dose of alcohol and a placebo. The blood oxygen level–dependent activation to an event-related visual working memory test was examined. Results The subjects exhibited longer response latencies and more errors as a function of increasing working memory load and showed a load-dependent increase in activation in dorsolateral prefrontal cortex, posterior parietal cortex, and visual cortex. Alcohol did not affect performance (errors or response latency), but attenuated the working memory load–dependent activation in the dorsolateral prefrontal cortex. During the placebo condition, individuals with a low level of response to alcohol showed greater activation in dorsolateral prefrontal cortex and posterior parietal cortex than those with a high level of response to alcohol. During the alcohol condition, groups showed similar attenuation of load-dependent brain activation in these regions. Conclusion Low-level responders relative to high-level responders exhibited an increased working memory load–dependent activation in dorsolateral prefrontal cortex and posterior parietal cortex when not exposed to alcohol. This increase in brain response was attenuated in low-level responders after ingesting a moderate dose of alcohol. PMID:16899039
Genetic overlap between impulsivity and alcohol dependence: a large-scale national twin study.
Khemiri, L; Kuja-Halkola, R; Larsson, H; Jayaram-Lindström, N
2016-04-01
Alcohol dependence is associated with increased levels of impulsivity, but the genetic and environmental underpinnings of this overlap remain unclear. The purpose of the current study was to investigate the degree to which genetic and environmental factors contribute to the overlap between alcohol dependence and impulsivity. Univariate and bivariate twin model fitting was conducted for alcohol dependence and impulsivity in a national sample of 16 819 twins born in Sweden from 1959 to 1985. The heritability estimate for alcohol dependence was 44% [95% confidence interval (CI) 31-57%] for males and 62% (95% CI 52-72%) for females. For impulsivity, the heritability was 33% (95% CI 30-36%) in males and females. The bivariate twin analysis indicated a statistically significant genetic correlation between alcohol dependence and impulsivity of 0.40 (95% CI 0.23-0.58) in males and 0.20 (95% CI 0.07-0.33) in females. The phenotypic correlation between alcohol dependence and impulsivity was 0.20 and 0.17 for males and females, respectively, and the bivariate heritability was 80% (95% CI 47-117%) for males and 53% (95% CI 19-86%) for females. The remaining variance in all models was accounted for by non-shared environmental factors. The association between alcohol dependence and impulsivity can be partially accounted for by shared genetic factors. The genetic correlation was greater in men compared with women, which may indicate different pathways to the development of alcohol dependence between sexes. The observed genetic overlap has clinical implications regarding treatment and prevention, and partially explains the substantial co-morbidity between alcohol dependence and psychiatric disorders characterized by impulsive behaviour.

Background: The etiology of alcohol dependence is a complex interplay of biopsychosocial factors. The genes for alcohol-metabolizing enzymes: Alcohol dehydrogenase (ADH2 and ADH3) and aldehyde dehydrogenase (ALDH2) exhibit functional polymorphisms. Vulnerability of alcohol dependence may also be in part due to heritable personality traits. Aim: To determine whether any association exists between polymorphisms of ADH2, ADH3 and ALDH2 and alcohol dependence syndrome in a group of Asian Indians. In addition, the personality of these patients was assessed to identify traits predisposing to alcoholism. Materials and Methods: In this study, 100 consecutive males with alcohol dependence syndrome attending the psychiatric outpatient department of a tertiary care service hospital and an equal number of matched healthy controls were included with their consent. Blood samples of all the study cases and controls were collected and genotyped for the ADH2, ADH3 and ALDH2 loci. Personality was evaluated using the neuroticism, extraversion, openness (NEO) personality inventory and sensation seeking scale. Results: Allele frequencies of ADH2*2 (0.50), ADH3*1 (0.67) and ALSH2*2 (0.09) were significantly low in the alcohol dependent subjects. Personality traits of NEO personality inventory and sensation seeking were significantly higher when compared to controls. Conclusions: The functional polymorphisms of genes coding for alcohol metabolizing enzymes and personality traits of NEO and sensation seeking may affect the propensity to develop dependence.

Animal models of alcoholism: neurobiology of high alcohol-drinking behavior in rodents.
McBride, W J; Li, T K
1998-01-01
This review discusses efforts to develop rodent models for the study of neurobiological mechanisms underlying chronic alcohol drinking, alcoholism, and abnormal alcohol-seeking behavior. Selective breeding has produced stable lines of rats that reliably exhibit high and (for comparison purposes) low voluntary alcohol consumption. In addition, animal models of chronic ethanol self-administration have been developed in rodents, who do not have a genetic predisposition for high alcohol-seeking behavior, to explore environmental influences in ethanol drinking and the effects of physical dependence on alcohol self-administration. The selectively bred high-preference animals reliably self-administer ethanol by free-choice drinking and operantly respond for oral ethanol in amounts that produce pharmacologically meaningful blood alcohol concentrations (50 to 200 mg% and higher). In addition, the alcohol-preferring rats will self-administer ethanol by intragastric infusion. With chronic free-choice drinking, the high alcohol-preferring rats develop tolerance to the high-dose effects of ethanol and show signs of physical dependence after the withdrawal of alcohol. Compared with nonpreferring animals, the alcohol-preferring rats are less sensitive to the sedative-hypnotic effects of ethanol and develop tolerance more quickly to high-dose ethanol. Nonselected common stock rats can be trained to chronically self-administer ethanol following its initial presentation in a palatable sucrose or saccharin solution, and the gradual replacement of the sucrose or saccharin with ethanol (the sucrose/saccharin-fade technique). Moreover, rats that are trained in this manner and then made dependent by ethanol-vapor inhalation or liquid diet increase their ethanol self-administration during the withdrawal period. Both the selectively bred rats and common-stock rats demonstrate "relapse" and an alcohol deprivation effect following 2 or more weeks of abstinence. Systemic administration of agents that (1) increase synaptic levels of serotonin (5-HT) or dopamine (DA); (2) activate 5-HT1A, 5-HT2, D2, D3, or GABA(A) receptors; or (3) block opioid and 5-HT3 receptors decrease ethanol intake in most animal models. Neurochemical, neuroanatomical, and neuropharmacological studies indicate innate differences exist between the high alcohol-consuming and low alcohol-consuming rodents in various CNS limbic structures. In addition, reduced mesolimbic DA and 5-HT function have been observed during alcohol withdrawal in common stock rats. Depending on the animal model under study, abnormalities in the mesolimbic dopamine pathway, and/or the serotonin, opioid, and GABA systems that regulate this pathway may underlie vulnerability to the abnormal alcohol-seeking behavior in the genetic animal models.
Does retigabine affect the development of alcohol dependence?--A pharmaco-EEG study.
Zwierzyńska, Ewa; Andrzejczak, Dariusz; Pietrzak, Bogusława
2016-01-12
New antiepileptic drugs have been investigated for their potential role in the treatment of alcohol dependence. One of these drugs is retigabine and this study examines the effect of retigabine co-administered with ethanol on the development of alcohol dependence and the course of acute withdrawal syndrome. A pharmaco-EEG method was used to examine this impact in selected brain structures of rabbits (midbrain reticular formation, hippocampus and frontal cortex). Retigabine was administered p.o. at a dose of 5mg/kg/day with ethanol ad libitum for 6 weeks and then alone for 2 weeks during an abstinence period. Changes in bioelectric activity, which demonstrated the inhibitory effect of alcohol on the brain structures, were already visible after 2 weeks of ethanol administration. In the abstinence period, changes were of a different nature and significant neuronal hyperactivity was observed, particularly in the midbrain reticular formation and the hippocampus. This findings reveal that retigabine decreased ethanol-induced changes during both alcohol administration and abstinence periods. In particular, the modulatory effect of retigabine on the hippocampus may be a significant element of its mechanism of action in alcohol dependence therapy. Copyright © 2015 Elsevier Ireland Ltd.

Childhood and Adolescent Predictors of Alcohol Abuse and Dependence in Young Adulthood*

2007-01-01
Objective To provide a comprehensive examination of childhood and adolescent predictors of alcohol abuse and dependence at age 21, theoretically guided by the social development model. Method Data were taken from an ethnically diverse urban sample of 808 students [51% male), surveyed at age 10 and followed prospectively to age 21 in 1996. Potential predictors of alcohol abuse and dependence at age 21 were measured at ages 10, 14 and 16. Relationships between these predictors and alcohol abuse and dependence were examined at each age, to assess changes in their patterns of prediction over time. Results Strong bonding to school, close parental monitoring of children and clearly defined family rules for behavior, appropriate parental rewards for good behaviors, high level of refusal skills and strong belief in the moral order predicted a lower risk for alcohol abuse and dependence at age 21. Of these, strong bonding to school consistently predicted lower alcohol abuse and dependence from all three ages (10, 14 and 16). By contrast, youths who had a higher risk of alcohol abuse and dependence at age 21 engaged in more problem behaviors, had more opportunities to be involved with antisocial individuals and spent more time with and were more bonded to those individuals, viewed fewer negative consequences from antisocial behaviors and held more favorable views on alcohol use. Of these, prior problem behaviors and antisocial opportunities and involvements at ages 10, 14 and 16 consistently predicted alcohol abuse and dependence at age 21. Conclusions These important malleable predictors, identifiable as early as age 10, provide potential intervention targets for the prevention of alcohol abuse and dependence in early adulthood.

Although negative affect is a common precipitant of alcohol relapse, there are few interventions for alcohol dependence that specifically target negative affect. In this Stage 1a/1b treatment development study, several affect regulation strategies (e.g., mindfulness, prolonged exposure, distress tolerance) were combined to create a new treatment supplement called Affect Regulation Training (ART), which could be added to enhance Cognitive-Behavioral Therapy (CBT) for alcohol dependence. A draft therapy manual was given to therapists and treatment experts before being administered to several patients who also provided input. After two rounds of manual development (Stage 1a), a pilot randomized clinical trial (N = 77) of alcohol-dependent outpatients who reported drinking often in negative affect situations was conducted (Stage 1b). Participants received 12-weekly, 90-minute sessions of either CBT for alcohol dependence plus ART (CBT + ART) or CBT plus a healthy lifestyles control condition (CBT + HLS). Baseline, end-of-treatment, and 3- and 6-month posttreatment interviews were conducted. For both treatment conditions, participant ratings of treatment satisfaction were high, with CBT + ART rated significantly higher. Drinking outcome results indicated greater reductions in alcohol use for CBT + ART when compared to CBT + HLS, with moderate effect sizes for percent days abstinent, drinks per day, drinks per drinking day, and percent heavy drinking days. Overall, findings support further research on affect regulation interventions for negative affect drinkers. PMID:23876455

Current pharmacological treatments for alcohol dependence have focused on reducing alcohol consumption, but to date there are few treatments that also address the negative affective symptoms during acute and protracted alcohol withdrawal which are often exacerbated in people with comorbid anxiety and depression. Selective serotonin reuptake inhibitors (SSRIs) are sometimes prescribed to ameliorate these symptoms but can exacerbate anxiety and cravings in a select group of patients. In this critical review, we discuss recent literature describing an association between alcohol dependence, the SERT linked polymorphic region (5-HTTLPR), and pharmacological response to SSRIs. Given the heterogeneity in responsiveness to serotonergic drugs across the spectrum of alcoholic subtypes, we assess the contribution of specific 5-HT circuits to discrete endophenotypes of alcohol dependence. 5-HT circuits play a distinctive role in reward, stress, and executive function which may account for the variation in response to serotonergic drugs. New optogenetic and chemogenetic methods for dissecting 5-HT circuits in alcohol dependence may provide clues leading to more effective pharmacotherapies. Although our current understanding of the role of 5-HT systems in alcohol dependence is incomplete, there is some evidence to suggest that 5-HT3 receptor antagonists are effective in people with the L/L genotype of the 5-HTTLPR polymorphism while SSRIs may be more beneficial to people with the S/L or S/S genotype. Studies that assess the impact of serotonin transporter polymorphisms on 5-HT circuit function and the subsequent development of alcohol use disorders will be an important step forward in treating alcohol dependence.

Previous findings have demonstrated that variants in nicotinic receptor genes are associated with nicotine, alcohol and cocaine dependence. Because of the substantial comorbidity, it has often been unclear whether a variant is associated with multiple substances or whether the association is actually with a single substance. To investigate the possible contribution of rare variants to the development of substance dependencies other than nicotine dependence, specifically alcohol and cocaine dependence, we undertook pooled sequencing of the coding regions and flanking sequence of CHRNA5, CHRNA3, CHRNB4, CHRNA6 and CHRNB3 in 287 African American and 1028 European American individuals from the Collaborative Study of the Genetics of Alcoholism (COGA). All members of families for whom any individual was sequenced (2504 African Americans and 7318 European Americans) were then genotyped for all variants identified by sequencing. For each gene, we then tested for association using FamSKAT. For European Americans, we find increased DSM-IV cocaine dependence symptoms (FamSKAT P = 2 × 10(-4)) and increased DSM-IV alcohol dependence symptoms (FamSKAT P = 5 × 10(-4)) among carriers of missense variants in CHRNB3. Additionally, one variant (rs149775276; H329Y) shows association with both cocaine dependence symptoms (P = 7.4 × 10(-5), β = 2.04) and alcohol dependence symptoms (P = 2.6 × 10(-4), β = 2.04). For African Americans, we find decreased cocaine dependence symptoms among carriers of missense variants in CHRNA3 (FamSKAT P = 0.005). Replication in an independent sample supports the role of rare variants in CHRNB3 and alcohol dependence (P = 0.006). These are the first results to implicate rare variants in CHRNB3 or CHRNA3 in risk for alcohol dependence or cocaine dependence.

Pavlovian processes are thought to play an important role in the development, maintenance and relapse of alcohol dependence, possibly by influencing and usurping ongoing thought and behavior. The influence of pavlovian stimuli on ongoing behavior is paradigmatically measured by pavlovian-to-instrumental transfer (PIT) tasks. These involve multiple stages and are complex. Whether increased PIT is involved in human alcohol dependence is uncertain. We therefore aimed to establish and validate a modified PIT paradigm that would be robust, consistent and tolerated by healthy controls as well as by patients suffering from alcohol dependence, and to explore whether alcohol dependence is associated with enhanced PIT. Thirty-two recently detoxified alcohol-dependent patients and 32 age- and gender-matched healthy controls performed a PIT task with instrumental go/no-go approach behaviors. The task involved both pavlovian stimuli associated with monetary rewards and losses, and images of drinks. Both patients and healthy controls showed a robust and temporally stable PIT effect. Strengths of PIT effects to drug-related and monetary conditioned stimuli were highly correlated. Patients more frequently showed a PIT effect, and the effect was stronger in response to aversively conditioned CSs (conditioned suppression), but there was no group difference in response to appetitive CSs. The implementation of PIT has favorably robust properties in chronic alcohol-dependent patients and in healthy controls. It shows internal consistency between monetary and drug-related cues. The findings support an association of alcohol dependence with an increased propensity towards PIT. © 2014 S. Karger AG, Basel.
Impact of Exposure to Childhood Maltreatment on Transitions to Alcohol Dependence in Women and Men.

Childhood maltreatment decreases age of first use and speeds the transition from first use to dependence (i.e., telescoping) for alcohol use, however, it is currently unknown whether this influence is the same for men and women. Analyses were conducted with the National Epidemiologic Survey on Alcohol and Related Conditions (n = 34,653). Outcome variables included age of alcohol initiation and time to onset of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition alcohol dependence. Predictor variables included gender and childhood maltreatment. Linear and Poisson regression analyses were conducted. Results demonstrated that in regard to age of drinking initiation, individuals who experienced childhood maltreatment initiated 1 year earlier than those without maltreatment, however, there was no interaction of this relationship with gender. Regarding the time to dependence, it was found that women who experienced childhood maltreatment demonstrated telescoping (shorter time between onset and dependence) compared to women without maltreatment and men (both with and without maltreatment). Women with a history of childhood maltreatment are particularly vulnerable to an accelerated time from initiation of alcohol use until dependence, a pattern indicative of increased negative alcohol-related outcomes. Findings highlight the need for development of gender-specific prevention efforts and behavioral treatments to aid in early intervention of problematic alcohol use in women. © The Author(s) 2015.
[Alcohol dependence in homeless men. Incidence, development and determinants].

Against the background of the complex relationship of alcoholism and homelessness, we investigated the question of whether homeless alcoholics and those with homes differed regarding biographical and clinical variables. Therefore, 49 of 72 (68.1%) homeless male visitors to a city kitchen in the center of Berlin, who had fulfilled the ICD-10 criteria for the alcohol-dependence syndrome, were compared with 141 outpatients of the addiction research unit of the Department of Psychiatry of the Free University of Berlin. It was found that homeless alcoholics had more psychosocial disadvantages than other alcoholics. They had been raised more frequently in families with an alcoholic father or mother and a higher number of children. The level of education and job qualification was lower in the homeless alcoholics. Early homelessness was predicted by a lack of sexual behavior (no partnership experienced) and a family history of alcoholism. In the interview, homeless alcoholics reported fewer symptoms of alcohol-dependence syndrome than other alcoholics; however, the first symptoms had been experienced earlier. Alcohol-related somatic and psychological consequences were reported more frequently in alcoholics with homes, whereas social problems were more common in the homeless subjects. The results are discussed in the light of methodological limitations and other reports on the topic.

To compare the performance of competing and complementary interventions for prevention or treatment of problem drinking and alcohol dependence. To provide an example of how health maximising decision-makers might use performance measures such as cost per quality adjusted life year (QALY) league tables to formulate an optimal package of interventions for problem drinking and alcohol dependence. A time-dependent state-transition model was used to estimate QALYs gained per person for each intervention as compared to usual care in the relevant target population. Cost per QALY estimates for each of the interventions fall below any putative funding threshold for developed economies. Interventions for problem drinkers appear to offer better value than interventions targeted at those with a history of severe physical dependence. Formularies such as Australia's Medicare should include a comprehensive package of interventions for problem drinking and alcohol dependence.

Background and Aims Problematic Internet use and excessive alcohol consumption have been associated with a host of maladaptive outcomes. Further, low (blunted) cardiovascular and stress hormone (e.g. cortisol) reactions to acute psychological stress are a feature of individuals with a range of adverse health and behavioural characteristics, including dependencies such as tobacco and alcohol addiction. The present study extended this research by examining whether behavioural dependencies, namely problematic Internet use, excessive alcohol consumption, and their comorbidity would also be associated with blunted stress reactivity. Methods A large sample of university students (N = 2313) were screened using Internet and alcohol dependency questionnaires to select four groups for laboratory testing: comorbid Internet and alcohol dependence (N = 17), Internet dependence (N = 17), alcohol dependence (N = 28), and non-dependent controls (N = 26). Cardiovascular activity and salivary cortisol were measured at rest and in response to a psychological stress protocol comprising of mental arithmetic and public speaking tasks. Results Neither problematic Internet behaviour nor excessive alcohol consumption, either individually or in combination, were associated with blunted cardiovascular or cortisol stress reactions. Discussion It is possible that problematic Internet behaviour and excessive alcohol consumption in a student population were not related to physiological reactivity as they may not reflect ingrained addictions but rather an impulse control disorder and binging tendency. Conclusions The present results serve to indicate some of the limits of the developing hypothesis that blunted stress reactivity is a peripheral marker of the central motivational dysregulation in the brain underpinning a wide range of health and behavioural problems.

Previous studies have documented that heightened impulsivity likely contributes to the development and maintenance of alcohol use disorders. However, there is still a lack of studies that comprehensively detected the brain changes associated with abnormal impulsivity in alcohol addicts. This study was designed to investigate the alterations in brain structure and functional connectivity associated with abnormal impulsivity in alcohol dependent patients. Brain structural and functional magnetic resonance imaging data as well as impulsive behavior data were collected from 20 alcohol dependent patients and 20 age- and sex-matched healthy controls respectively. Voxel-based morphometry was used to investigate the differences of grey matter volume, and tract-based spatial statistics was used to detect abnormal white matter regions between alcohol dependent patients and healthy controls. The alterations in resting-state functional connectivity in alcohol dependent patients were examined using selected brain areas with gray matter deficits as seed regions. Compared with healthy controls, alcohol dependent patients had significantly reduced gray matter volume in the mesocorticolimbic system including the dorsal posterior cingulate cortex, the dorsal anterior cingulate cortex, the medial prefrontal cortex, the orbitofrontal cortex and the putamen, decreased fractional anisotropy in the regions connecting the damaged grey matter areas driven by higher radial diffusivity value in the same areas and decreased resting-state functional connectivity within the reward network. Moreover, the gray matter volume of the left medial prefrontal cortex exhibited negative correlations with various impulse indices. These findings suggest that chronic alcohol dependence could cause a complex neural changes linked to abnormal impulsivity.

This article represents one of five contributions focusing on the topic “Plasticity and neuroadaptive responses within the extended amygdala in response to chronic or excessive alcohol exposure” that were developed by awardees participating in the Young Investigator Award Symposium at the “Alcoholism and Stress: A Framework for Future Treatment Strategies” conference in Volterra, Italy on May 3–6, 2011 that was organized/chaired by Drs. Antonio Noronha and Fulton Crews and sponsored by the National Institute on Alcohol Abuse and Alcoholism. This review discusses the dependence-induced neuroadaptations in affective systems that provide a basis for negative reinforcement learning and presents evidence demonstrating that escalated alcohol consumption during withdrawal is a learned, plasticity-dependent process. The review concludes by identifying changes within extended amygdala dynorphin/kappa-opioid receptor systems that could serve as the foundation for the occurrence of negative reinforcement processes. While some evidence contained herein may be specific to alcohol dependence-related learning and plasticity, much of the information will be of relevance to any addictive disorder involving negative reinforcement mechanisms. Collectively, the information presented within this review provides a framework to assess the negative reinforcing effects of alcohol in a manner that distinguishes neuroadaptations produced by chronic alcohol exposure from the actual plasticity that is associated with negative reinforcement learning in dependent organisms.

Small-conductance Ca(2+)-activated K(+) (KCa2) channels control neuronal excitability and synaptic plasticity, and have been implicated in substance abuse. However, it is unknown if genes that encode KCa2 channels (KCNN1-3) influence alcohol and drug addiction. In the present study, an integrative functional genomics approach shows that genetic datasets for alcohol, nicotine, and illicit drugs contain the family of KCNN genes. Alcohol preference and dependence QTLs contain KCNN2 and KCNN3, and Kcnn3 transcript levels in the nucleus accumbens (NAc) of genetically diverse BXD strains of mice predicted voluntary alcohol consumption. Transcript levels of Kcnn3 in the NAc negatively correlated with alcohol intake levels in BXD strains, and alcohol dependence enhanced the strength of this association. Microinjections of the KCa2 channel inhibitor apamin into the NAc increased alcohol intake in control C57BL/6J mice, while spontaneous seizures developed in alcohol-dependent mice following apamin injection. Consistent with this finding, alcohol dependence enhanced the intrinsic excitability of medium spiny neurons in the NAc core and reduced the function and protein expression of KCa2 channels in the NAc. Altogether, these data implicate the family of KCNN genes in alcohol, nicotine, and drug addiction, and identify KCNN3 as a mediator of voluntary and excessive alcohol consumption. KCa2.3 channels represent a promising novel target in the pharmacogenetic treatment of alcohol and drug addiction.
Alcohol use disorders and current pharmacological therapies: the role of GABAA receptors
Liang, Jing; Olsen, Richard W

Alcohol use disorders (AUD) are defined as alcohol abuse and alcohol dependence, which create large problems both for society and for the drinkers themselves. To date, no therapeutic can effectively solve these problems. Understanding the underlying mechanisms leading to AUD is critically important for developing effective and safe pharmacological therapies. Benzodiazepines (BZs) are used to reduce the symptoms of alcohol withdrawal syndrome. However, frequent use of BZs causes cross-tolerance, dependence, and cross-addiction to alcohol. The FDA-approved naltrexone and acamprosate have shown mixed results in clinical trials. Naltrexone is effective to treat alcohol dependence (decreased length and frequency of drinking bouts), but its severe side effects, including withdrawal symptoms, are difficult to overcome. Acamprosate showed efficacy for treating alcohol dependence in European trials, but two large US trials have failed to confirm the efficacy. Another FDA-approved medication, disulfiram, does not diminish craving, and it causes a peripheral neuropathy. Kudzu is the only natural medication mentioned by the National Institute on Alcohol Abuse and Alcoholism, but its mechanisms of action are not yet established. It has been recently shown that dihydromyricetin, a flavonoid purified from Hovenia, has unique effects on GABAA receptors and blocks ethanol intoxication and withdrawal in alcoholic animal models. In this article, we review the role of GABAA receptors in the treatment of AUD and currently available and potentially novel pharmacological agents. PMID:25066321

The family of patient suffering from alcoholism was investigated form the standpoints of systemic analysis, that allowed revealing the leading personal characteristics of married couples. The men suffering from alcoholism are characterized by weak will, inclination to dependence, disregard of behavioral social norms, increased excitability and tendency to frustration in combination with high level of aggressiveness against the background of decreased masculine and prevailing feminine characteristics. Co-dependent wives of men suffering from alcoholism are characterized by predominance, observance of social norms, pronounced autoagression and orientation to masculine characteristics against the background of high indices of both femininity and masculinity. Such combination of married couples' personal characteristics forms the basis for development of dysfunctional relations in a family of man suffering from alcoholism. The families where husband and wife had no alcohol dependence, with harmonic functional relations served as the control group.

This paper proposes a novel hypothetical model integrating formerly discrete theories of stress appraisal, neurobiological allostasis, automatic cognitive processing, and addictive behavior to elucidate how alcohol misuse and dependence are maintained and re-activated by stress. We outline a risk chain in which psychosocial stress initiates physiological arousal, perseverative cognition, and negative affect that, in turn, triggers automatized schema to compel alcohol consumption. This implicit cognitive process then leads to attentional biases toward alcohol, subjective experiences of craving, paradoxical increases in arousal and alcohol-related cognitions due to urge suppression, and palliative coping through drinking. When palliative coping relieves distress, it results in negative reinforcement conditioning that perpetuates the cycle by further sensitizing the system to future stressful encounters. This model has implications for development and implementation of innovative behavioral interventions (such as mindfulness training) that disrupt cognitive-affective mechanisms underpinning stress-precipitated dependence on alcohol.

This review represents the focus of a symposium that was presented at the “Alcoholism and Stress: A Framework for Future Treatment Strategies” conference in Volterra, Italy on May 3–6, 2011 and organized / chaired by Dr. Brendan M. Walker. The primary goal of the symposium was to evaluate and disseminate contemporary findings regarding the emerging role of kappa-opioid receptors (KORs) and their endogenous ligands dynorphins (DYNs) in the regulation of escalated alcohol consumption, negative affect and cognitive dysfunction associated with alcohol dependence, as well as DYN / KOR mediation of the effects of chronic stress on alcohol reward and seeking behaviors. Dr. Glenn Valdez described a role for KORs in the anxiogenic effects of alcohol withdrawal. Dr. Jay McLaughlin focused on the role of KORs in repeated stress-induced potentiation of alcohol reward and increased alcohol consumption. Dr. Brendan Walker presented data characterizing the effects of KOR antagonism within the extended amygdala on withdrawal-induced escalation of alcohol self-administration in dependent animals. Dr. Georgy Bakalkin concluded with data indicative of altered DYNs and KORs in the prefrontal cortex of alcohol dependent humans that could underlie diminished cognitive performance. Collectively, the data presented within this symposium identified the multifaceted contribution of KORs to the characteristics of acute and chronic alcohol-induced behavioral dysregulation and provided a foundation for the development of pharmacotherapeutic strategies to treat certain aspects of alcohol use disorders.

Reducing Underage and Young Adult Drinking
Windle, Michael; Zucker, Robert A.
2010-01-01
Forty years ago, when the National Institute on Alcohol Abuse and Alcoholism (NIAAA) was founded, alcoholism was considered an adult disease driven principally by physiological determinants. As NIAAA expanded its research portfolio, new data and insights were obtained that led to an increased focus on underage and young adult drinking. Fostered by interdisciplinary research, etiologic models were developed that recognized the multiplicity of relevant genetic and environmental influences. This shift in conceptualizing alcohol use disorders also was based on findings from large-scale, national studies indicating that late adolescence and early young adulthood were peak periods for the development of alcohol dependence and that early initiation of alcohol use (i.e., before age 15) was associated with a fourfold increase in the probability of subsequently developing alcohol dependence. In recent years, developmental studies and models of the initiation, escalation, and adverse consequences of underage and early young adult drinking have helped us to understand how alcohol use may influence, and be influenced by, developmental transitions or turning points. Major risk and protective factors are being identified and integrated into screening, prevention, and treatment programs to optimize interventions designed to reduce drinking problems among adolescents and young adults. In addition, regulatory policies, such as the minimum drinking age and zero-tolerance laws, are being implemented and evaluated for their impact on public health. PMID:23579934

Alcohol dependence is a disorder ascribable to multiple factors and leads to cognitive impairment. Given that insulin dysregulation can cause cognitive impairment, patients with alcohol dependence are likely to develop insulin dysregulation such as that in diabetes. The purposes of this study are to identify an association between cognitive functioning and insulin and to investigate insulin as the biomarker of cognitive functioning in alcohol-dependent patients. Serum insulin levels were measured and cognitive functions were assessed in 45 patients with chronic alcoholism. The Korean version of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K), a battery of cognitive function tests, was used to assess cognitive functioning. Serum insulin levels were not significantly correlated with most CERAD-K scores, but there was a significant negative correlation with scores on the Trail Making Test B, which is designed to measure executive functioning. Lower serum insulin levels were associated with slower executive functioning responses on the Trail Making Test B, suggesting that executive functioning may be in proportion to serum insulin levels. Thus, in patients with alcohol dependence, insulin level is associated with cognitive functioning. In addition, the present findings suggest that insulin level is a potential biomarker for determining cognitive functioning.
Alcoholism: recent advances in epidemiology, biochemistry and genetics.

Countries traditionally consuming beer and wine have high alcohol consumption as compared to East Asia, where the fact of low alcoholism prevalence can be attributed to a defect in metabolic degradation of ethanol. Dependence on alcohol is multifactorial and is related to a complex interplay of metabolic, genetic, social and environmental factors. Repetitive alcohol ingestion and its resulting dependence is associated with false euphoria triggered by an inhibition of glutamate receptors and other brain neurotransmitters, namely dopamine and serotonine. Genetic polymorphisms of genes encoding the alcohol metabolism enzymes and neurotransmitter signaling molecules in dopamine, gamma aminobutyric acid, opioid and serotonin systems, are involved in individual variations for susceptibility to alcohol dependence. Prominent progress has been achieved toward identification of genes related to alcoholism. Six genes were described on chromosomes 4, 7, 8, 11, 15 and 20, which are known to have influence on neuronal signal transfer and generation of dopamine receptors. It is suggested that such genes carry the risk for alcoholism. In the last years, the role of (GABA) receptors in the development of alcoholism is studied in detail. In future it may be possible to separate the genetic, enzymatic and environmental factors that are responsible for increased vulnerability of some individuals to alcohol abuse (Fig. 2, Tab. 1, Ref. 19).

Acylethanolamides are a family of endogenous lipid mediators that are involved in physiological and behavioral processes associated with addiction. Recently, oleoylethanolamide (OEA) has been reported to reduce alcohol intake and relapse in rodents but the contribution of OEA and other acylethanolamides in alcohol addiction in humans is unknown. The present study is aimed to characterize the plasma acylethanolamides in alcohol dependence. Seventy-nine abstinent alcohol-dependent subjects (27 women) recruited from outpatient treatment programs and age-/sex-/body mass-matched healthy volunteers (28 women) were clinically assessed with the diagnostic interview PRISM according to the DSM-IV-TR after blood extraction for quantification of acylethanolamide concentrations in the plasma. Our results indicate that all acylethanolamides were significantly increased in alcohol-dependent patients compared with control subjects (p < 0.001). A logistic model based on these acylethanolamides was developed to distinguish alcohol-dependent patients from controls and included OEA, arachidonoylethanolamide (AEA) and docosatetraenoylethanolamide (DEA), providing a high discriminatory power according to area under the curve [AUC = 0.92 (95%CI: 0.87-0.96), p < 0.001]. Additionally, we found a significant effect of the duration of alcohol abstinence on the concentrations of OEA, AEA and DEA using a regression model (p < 0.05, p < 0.01 and p < 0.001, respectively), which was confirmed by a negative correlation (rho = -0.31, -0.40 and -0.44, respectively). However, acylethanolamides were not influenced by the addiction alcohol severity, duration of problematic alcohol use or diagnosis of psychiatric comorbidity. Our results support the preclinical studies and suggest that OEA, AEA and DEA are altered in alcohol-dependence during abstinence and that might act as potential markers for predicting length of alcohol abstinence. © 2016 Society for the Study of Addiction.

The aim of this study was to analyze the connection between alcohol dependence and criminal behavior by an integrated genetic-environmental approach. The research, structured as a case-control study, examined 186 alcohol-dependent males; group 1 (N = 47 convicted subjects) was compared with group 2 (N = 139 no previous criminal records). Genetic results were innovative, highlighting differences in genotype distribution (p = 0.0067) in group 1 for single-nucleotide polymorphism rs 3780428, located in the intronic region of subunit 2 of the GABA B receptor gene (GABBR2). Some environmental factors (e.g., grade repetition) were associated with criminal behavior; others (e.g., attendance at Alcoholics Anonymous) were inversely related to convictions. The concomitant presence of the genetic and environmental factors found to be associated with the condition of alcohol-dependent inmate showed a 4-fold increase in the risk of antisocial behavior. The results need to be replicated on a larger population to develop new preventive and therapeutic proposals. © 2013 American Academy of Forensic Sciences.
Acute impact of caffeinated alcoholic beverages on cognition: A systematic review.
Lalanne, Laurence; Lutz, Pierre-Eric; Paille, François
2017-06-02
Energy drinks are popular beverages that are supposed to counteract sleepiness, increase energy, maintain alertness and reduce symptoms of hangover. Cognitive enhancing seems to be related to many compounds such as caffeine, taurine and vitamins. Currently, users mostly combine psychostimulant effects of energy drinks to counteract sedative effects of alcohol. However, recent literature suggests that this combination conducts to feel less intoxicated but still impaired. The goal of the present article is to review cognitive impact and subjective awareness in case of caffeinated alcoholic beverage (CAB) intoxication. PubMed (January 1960 to March 2016) database was searched using the following terms: cognitive impairments, alcohol, energy drinks; cognition, alcohol, caffeine. 99 papers were found but only 12 randomized controlled studies which explored cognitive disorders and subjective awareness associated with acute CAB or AED (alcohol associated with energy drinks) intoxication were included. The present literature review confirmed that energy drinks might counteract some cognitive deficits and adverse effects of alcohol i.e. dry mouth, fatigue, headache, weakness, and perception of intoxication due to alcohol alone. This effect depends on alcohol limb but disappears when the complexity of the task increases, when driving for example. Moreover, studies clearly showed that CAB/AEDs increase impulsivity which conducts to an overconsumption of alcohol and enhanced motivation to drink compared to alcohol alone, potentiating the risk of developing addictive behaviors. This is a huge problem in adolescents with high impulsivity and immature decision making processes. Although energy drinks counteract some cognitive deficits due to alcohol alone, their association promotes the risk of developing alcohol addiction. As a consequence, it is necessary to better understand the neurobiological mechanisms underlying these interactions in order to better prevent the development of alcohol dependence.

Although several studies have explored craving for certain drugs, there is limited data describing the relationship between alcohol and nicotine craving from a multidimensional perspective among individuals with comorbid nicotine dependence (ND) and alcohol dependence (AD). We compared a group of male patients diagnosed with ND and AD (n = 160) to a group of male patients diagnosed with ND only (n = 235). Smoking- and drinking-related clinical features were measured, including craving levels and the Nicotine Dependence Syndrome Scale (NDSS), which is a multidimensional questionnaire measuring ND. Subsequently, we studied factors that influenced smoking and alcohol craving in the ND and AD group. Regarding the NDSS, the sum, priority and tolerance scores were significantly higher in the ND and AD group compared with the ND only group (P < 0.000, P < 0.000 and P = 0.001, respectively). In the comorbid group, regression analyses revealed that alcohol craving and Fagerstrom Test for Nicotine Dependence (FTND) scores contributed to nicotine craving (beta coefficient = 0.37, P = 0.005 and beta coefficient = 0.35, P = 0.026, respectively) and these two factors explained 36% of the variance). Nicotine craving appeared to be the only factor that contributed to alcohol craving (beta coefficient = 0.35, P = 0.002), and nicotine craving explained 16% of the variance. This study may help clarify the clinical relationship between comorbid alcohol and nicotine dependence and help guide the development of effective treatment strategies for ND and AD patients.

Offspring from families with multiple cases of alcohol dependence have a greater likelihood of developing alcohol dependence (AD) and related substance use disorders. Greater susceptibility for developing these disorders may be related to structural differences in brain circuits that influence the salience of rewards or modify the efficiency of information processing and AD susceptibility. We examined the cerebellum of 71 adolescent/young adult high-risk (HR) offspring from families with multiple cases of alcohol dependence (multiplex families), and 60 low-risk (LR) controls with no family history of alcohol or drug dependence who were matched for age, gender, socioeconomic status and IQ, with attention given to possible effects of personal use of substances and maternal use during pregnancy. Magnetic resonance images were acquired on a General Electric 1.5-Tesla scanner and manually traced (BRAINS2) blind to clinical information. GABRA2 and BDNF variation were tested for their association with cerebellar volumes. High-risk offspring from multiplex AD families showed greater total volume of the cerebellum and total gray matter (GM), in comparison with LR controls. An interaction between allelic variation in GABRA2 and BDNF genes was associated with GM volumes, suggesting that inherited variation in these genes may promote early developmental differences in neuronal proliferation of the cerebellum.

Mobile phone use has increased dramatically and concurrent with rapid developments in mobile phone-based health interventions. The integration of text messaging interventions promises to optimise the delivery of care for persons with substance dependence with minimal disruption to clinical workflows. We conducted a systematic review to assess the acceptability, feasibility and clinical impact of text messaging interventions for persons with illicit drug and alcohol dependence. Studies were required to evaluate the use of text messaging as an intervention for persons who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition criterion for a diagnosis of illicit drug and/or alcohol dependence. Authors searched for articles published to date in MEDLINE (pubmed.gov), the Cochrane Library, EMBASE, CINAHL, Google Scholar and PsychINFO. Eleven articles met the search criteria for this review and support the acceptability and feasibility of text messaging interventions for addressing illicit drug and alcohol dependence. Most studies demonstrated improved clinical outcomes, medication adherence and engagement with peer support groups. Text messaging interventions also intervened on multiple therapeutic targets such as appointment attendance, motivation, self-efficacy, relapse prevention and social support. Suggestions for future research are described, including intervention design features, clinician contact, privacy measures and integration of behaviour change theories. Text messaging interventions offer a feasible platform to address a range of substances (i.e. alcohol, methamphetamine, heroin and alcohol), and there is increasing evidence supporting further larger-scale studies.

Understanding the temporal sequencing of alcohol use disorders (AUDs) and comorbid mood and anxiety disorders may help to disentangle the etiological underpinnings of comorbidity. Methodological limitations of previous studies, however, may have led to inconsistent or inconclusive findings. To describe the temporal sequencing of the onset of AUDs relative to the onset of specific comorbid mood and anxiety disorders using a large, nationally representative survey. AUD onset tended to follow the onset of 2 of the 9 mood and anxiety disorders (specific and social phobia). The onset of alcohol abuse tended to precede the onset of 5 of the 9 mood and anxiety disorders (GAD, panic, panic with agoraphobia, major depression, and dysthymia), whereas the onset of alcohol dependence tended to precede the onset of only 2 of the 9 mood and anxiety disorders (GAD and panic). Lag times between primary and subsequent disorders generally ranged from 7 to 16 years. Comorbid individuals whose alcohol dependence came after panic with agoraphobia, hypomania, and GAD had increased risk of persistent alcohol dependence. Alcohol abuse, but not dependence, precedes many mood and anxiety disorders. If the primary disorder does in fact play a causative or contributing role in the development of the subsequent disorder, this role can best be described as "temporally distal." However, in assessing the risk for persistent alcohol dependence, clinicians should not only consider the type of comorbid mood/anxiety disorder, but also the temporal ordering of these disorders.

It is unclear how temperament is related to alcohol-related behavior in large population studies. We have used the Affective and Emotional Composite Temperament Scale (AFECTS) model to evaluate how emotional traits and affective temperaments are associated with alcohol use, abuse, and dependence in the general population. Data from 10,603 subjects (mean age=28.0±7.8 years, 70.3% females) was collected anonymously by the Internet in Brazil using the AFECTS model and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). Alcohol use was stratified into control, low use, abuse, and dependence groups. The analysis of dimensional traits showed that Volition and Coping were lower, and Sensitivity was higher, in the abuse and dependence groups, with no differences between the Control and the Low Use groups. Alcohol consumption was also associated with lower Control, Stability, and Caution, and higher with Anger, Anxiety, and Desire, with significant differences between all groups. Regarding affective temperament types, alcohol abuse and dependence were associated with euphoric and cyclothymic temperaments in both genders, which was mirrored by a lower frequency of both euthymic and hyperthymic types. Only hyperthymics were overrepresented in the Control group for both genders. Data was collected by Internet only. A global dysfunction of emotional traits and a predominance of cyclothymic and euphoric temperaments were associated with alcohol-related behavior. Prevention and treatment strategies may be developed more effectively if these traits are taken into account. Copyright © 2014 Elsevier B.V. All rights reserved.

Alcohol relapse after liver transplant heightens concern about recurrent disease, nonadherence to the immunosuppression regimen, and death. To develop a scoring system to stratify risk of alcohol relapse after liver transplant. Retrospective medical record review. All adult liver transplants performed from May 2002 to February 2011 at a single center in the United States. The incidence of return to any alcohol consumption after liver transplant. Thirty-four percent (40/118) of patients with a history of alcohol abuse/dependency relapsed to use of any alcohol after liver transplant. Nine of 25 hypothesized risk factors were predictive of alcohol relapse after liver transplant: absence of hepatocellular carcinoma, tobacco dependence, continued alcohol use after liver disease diagnosis, low motivation for alcohol treatment, poor stress management skills, no rehabilitation relationship, limited social support, lack of nonmedical behavioral consequences, and continued engagement in social activities with alcohol present. Each independent predictor was assigned an Alcohol Relapse Risk Assessment (ARRA) risk value of 1 point, and patients were classified into 1 of 4 groups by ARRA score: ARRA I = 0, ARRA II = 1 to 3, ARRA III = 4 to 6, and ARRA IV = 7 to 9. Patients in the 2 higher ARRA classifications had significantly higher rates of alcohol relapse and were more likely to return to pretransplant levels of drinking. Alcohol relapse rates are moderately high after liver transplant. The ARRA is a valid and practical tool for identifying pretransplant patients with alcohol abuse or dependency at elevated risk of any alcohol use after liver transplant.

Microglia are involved in various homeostatic processes in the brain, including phagocytosis, apoptosis, and synaptic pruning. Sex differences in microglia colonization of the developing brain have been reported, but have not been established following alcohol insult. Developmental alcohol exposure represents a neuroimmune challenge that may contribute to cognitive dysfunction prevalent in humans with Fetal Alcohol Spectrum Disorders (FASD) and in rodent models of FASD. Most studies have investigated neuroimmune activation following adult alcohol exposure or following multiple exposures. The current study uses a single day binge alcohol exposure model (postnatal day [PD] 4) to examine sex differences in the neuroimmune response in the developing rat hippocampus on PD5 and 8. The neuroimmune response was evaluated through measurement of microglial number and cytokine gene expression at both time points. Male pups had higher microglial number compared to females in many hippocampal subregions on PD5, but this difference disappeared by PD8, unless exposed to alcohol. Expression of pro-inflammatory marker CD11b was higher on PD5 in alcohol-exposed (AE) females compared to AE males. After alcohol exposure, C-C motif chemokine ligand 4 (CCL4) was significantly increased in female AE pups on PD5 and PD8. Tumor necrosis factor-α (TNF-α) levels were also upregulated by AE in males on PD8. The results demonstrate a clear difference between the male and female neuroimmune response to an AE challenge, which also occurs in a time-dependent manner. These findings are significant as they add to our knowledge of specific sex-dependent effects of alcohol exposure on microglia within the developing brain.

Nurses are often the first point of contact for patients hospitalized due to alcohol-related causes. Alcohol dependence is highly stigmatized and as a result healthcare professionals often have low behavioural intentions, meaning low willingness to care for these patients. This can have a direct influence on quality of care. The purpose of this study was to explore enrolled nursing students' intention to care for patients with alcohol dependence and the antecedents, preliminary factors, that predict this within the Theory of Planned Behaviour; specifically attitudes, subjective norms, self-efficacy and controllability. The study was a cross-sectional survey using the Theory of Planned Behaviour. Two Technical and Further Education South Australia campuses across metropolitan Adelaide. n=86 enrolled nursing students completed the survey (62% response rate). Enrolled nursing students' intention, attitudes, subjective norms, self-efficacy and controllability were measured using a Theory of Planned Behaviour Questionnaire. The Short Alcohol and Alcohol Problems Perception Questionnaire investigated attitudes in more detail and a short knowledge scale assessed alcohol-related knowledge. Subjective norms and attitudes had a significant, positive effect on intention to care within the final model, accounting for 22.6% of the variance, F2,83=12.12, p<0.001. Subjective norms were the strongest predictor. External factors such as age, previous alcohol training and alcohol-related knowledge held direct paths to antecedents of intention. Subjective norms were the strongest predictor of intention to care for patients with alcohol dependence, followed by attitudes. The study provides an understanding of enrolled nursing students' intention to care for alcohol dependent patients. These findings can assist in developing tailored alcohol training for students, to increase attitudes and foster behavioural change, in order to improve the quality of care for these patients.

Component processes of memory in alcoholism: pattern of compromise and neural substrates.
Pitel, Anne-Lise; Eustache, Francis; Beaunieux, Helene
2014-01-01
Initially, alcohol-related memory deficits were considered only through the prism of Korsakoff's syndrome (KS). It is now clear, however, that chronic alcohol consumption results in memory disorders in alcoholics without ostensible neurologic complications, such as Wernicke's encephalopathy and KS. Most of the principal memory components are affected, including working memory, episodic memory, semantic memory, perceptual memory, and procedural memory. The extent of those cognitive impairments depends on several factors, such as age, gender, nutritional status, and psychiatric comorbidity. While memory disorders, especially episodic memory deficits, are largely definitive in patients with KS, recovery of memory abilities has been described with abstinence in uncomplicated alcoholics. Neuropsychologic impairments, and especially memory disorders, must be evaluated at alcohol treatment entry because they could impede patients from benefiting fully from cognitive and behavioral treatment approaches for alcohol dependence. Screening of memory deficits could also enable clinicians to detect, among alcoholics without ostensible neurologic complications, those at risk of developing permanent and debilitating amnesia that features KS. © 2014 Elsevier B.V.

The purpose of this study was to develop an evaluation method for animal-assisted intervention (AAI) programs involving Mood Check List-Short form.2 (MCL-S.2) and the State-Trait Anxiety Inventory (STAI) for psychiatric daycare of Japanese alcohol. dependents. A total of 36 alcohol dependents completed the study and questionnaires assessing their state. A single session of AAI reduced both subjective and physiological measures of state anxiety (A-State); and this program induced a significant reduction in the anxiety after an AAI program session with the dogs and cats involved in the intervention (p = 0.001). The Wilcoxon t-test showed that there were also significant differences in the "anxiety", "pleasantness", and "relaxation". scores for MCL-S.2 among the alcohol dependents, before and after AAI; a significantly decreased "anxiety" score (p = 0.006), and increased "pleasantness" (p = 0.002) and "relaxation" (p=0.012) scores for MCL-S.2 after AAI. The results of this study indicated that alcohol dependents who experienced a group AAI session-program exhibited significant improvements in their feeling; decreased anxiety, and increased pleasantness and relaxation.

Both alcohol-specific genetic factors and genetic factors related to externalizing behavior influence problematic alcohol use. Little is known, however, about the etiologic role of these 2 components of genetic risk on alcohol-related behaviors across development. Prior studies conducted in a male cohort of twins suggest that externalizing genetic factors are important for predicting heavy alcohol use in adolescence, whereas alcohol-specific genetic factors increase in importance during the transition to adulthood. In this report, we studied twin brothers and sisters and brother-sister twin pairs to examine such developmental trajectories and investigate whether sex and cotwin sex effects modify these genetic influences. We used prospective, longitudinal twin data collected between ages 12 and 22 within the population-based FinnTwin12 cohort study (analytic n = 1,864). Our dependent measures of alcohol use behaviors included alcohol initiation (age 12), intoxication frequency (ages 14 and 17), and alcohol dependence criteria (age 22). Each individual's genetic risk of alcohol use disorders (AUD-GR) was indexed by his/her parents' and cotwin's DSM-IV Alcohol Dependence (AD) criterion counts. Likewise, each individual's genetic risk of externalizing disorders (EXT-GR) was indexed with a composite measure of parents' and cotwin's DSM-IV Conduct Disorder and Antisocial Personality Disorder criterion counts. EXT-GR was most strongly related to alcohol use behaviors during adolescence, while AUD-GR was most strongly related to alcohol problems in young adulthood. Further, sex of the twin and sex of the cotwin significantly moderated the associations between genetic risk and alcohol use behaviors across development: AUD-GR influenced early adolescent alcohol use behaviors in females more than in males, and EXT-GR influenced age 22 AD more in males than in females. In addition, the associations of AUD-GR and EXT-GR with intoxication frequency were greater among 14- and 17-year-old females with twin brothers. We found divergent developmental trajectories for alcohol-specific and externalizing behavior-related genetic influences on alcohol use behaviors; in early adolescence, genetic influences on alcohol use behaviors are largely nonspecific, and later in adolescence and young adulthood, alcohol-specific genetic influences on alcohol use are more influential. Importantly, within these overall trajectories, several interesting sex differences emerged. We found that the relationship between genetic risk and problematic drinking across development is moderated by the individual's sex and his/her cotwin's sex. AUD-GR influenced adolescent alcohol outcomes in females more than in males and by age 22, EXT-GR influenced AD criteria more for males than females. In addition, the association between genetic risk and intoxication frequency was greater among 14- and 17-year-old females with male cotwins. Copyright © 2014 by the Research Society on Alcoholism.

Low monoamine oxidase (MAO) activity and the neurotransmitter dopamine are 2 important factors in the development of alcohol dependence. MAO is an important enzyme associated with the metabolism of biogenic amines. Therefore, the present study investigates whether the association between the dopamine D2 receptor (DRD2) gene and alcoholism is affected by different polymorphisms of the MAO type A (MAOA) gene. A total of 427 Han Chinese men in Taiwan (201 control subjects and 226 with alcoholism) were recruited for the study. Of the subjects with alcoholism, 108 had pure alcohol dependence (ALC) and 118 had both alcohol dependence and anxiety, depression or both (ANX/DEP ALC). All subjects were assessed with the Chinese Version of the Modified Schedule of Affective Disorders and Schizophrenia-Lifetime. Alcohol dependence, anxiety and major depressive disorders were diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria. The genetic variant of the DRD2 gene was only associated with the ANX/DEP ALC phenotype, and the genetic variant of the MAOA gene was associated with pure ALC. Subjects carrying the MAOA 3-repeat allele and genotype A1/A1 of the DRD2 were 3.48 times (95% confidence interval = 1.47-8.25) more likely to be ANX/DEP ALC than the subjects carrying the MAOA 3-repeat allele and DRD2 A2/A2 genotype. The MAOA gene may modify the association between the DRD2 gene and ANX/DEP ALC phenotype.

Substance-related and addictive disorders are chronic relapsing conditions that substantially impact public health. Effective treatments for these disorders require addressing substance use/dependence comprehensively as well as other associated comorbidities. Comprehensive addressing of substance use in a medical setting involves screening for substance use, addressing substance use directly with the patient, and formulating an appropriate intervention. For alcohol dependence and opioid dependence, pharmacotherapies are available that are safe and effective when utilized in a comprehensive treatment paradigm, such as medication assisted treatment. In primary care, substance use disorders involving alcohol, illicit opioids, and prescription opioid abuse are common among patients who seek primary care services. Primary care providers report low levels of preparedness and confidence in identifying substance-related and addictive disorders and providing appropriate care and treatment. However, new models of service delivery in primary care for individuals with substance-related and addictive disorders are being developed to promote screening, care and treatment, and relapse prevention. The education and training of primary care providers utilizing approved medications for the treatment of alcohol use disorders and opioid dependence in a primary care setting would have important public health impact and reduce the burden of alcohol abuse and opioid dependence.

Substance use disorder is a serious health problem that tends to manifest in late adolescence. Attempting to influence targetable risk and protective factors holds promise for prevention and treatment. Survey data from 1,253 college students (48.5% male, 26.9% non-White) were used to investigate the independent and combined effects of two prominent factors, sensation seeking and parental monitoring, on the probability of alcohol and/or cannabis dependence during the first year of college. In multivariate analyses that controlled for high school use, gender, race, mother’s education, and importance of religion, retrospective reports by the student of parental behavior during the last year of high school indicated that higher levels of parental monitoring had a direct effect on reducing risk for alcohol dependence during the first year of college, but not on cannabis dependence. High levels of sensation seeking were associated with increased risk for both alcohol and cannabis dependence. No interaction effects were found. The results extend prior findings by highlighting influences of pre-college parental monitoring and sensation seeking on the probability of alcohol and/or cannabis dependence during the first year of college. The findings also suggest that these two factors are useful in identifying college students at high risk for alcohol and/or cannabis dependence. PMID:23017733
Alcohol and the sleeping brain.
Colrain, Ian M; Nicholas, Christian L; Baker, Fiona C

Alcohol acts as a sedative that interacts with several neurotransmitter systems important in the regulation of sleep. Acute administration of large amounts of alcohol prior to sleep leads to decreased sleep-onset latency and changes in sleep architecture early in the night, when blood alcohol levels are high, with subsequent disrupted, poor-quality sleep later in the night. Alcohol abuse and dependence are associated with chronic sleep disturbance, lower slow-wave sleep, and more rapid-eye-movement sleep than normal, that last long into periods of abstinence and may play a role in relapse. This chapter outlines the evidence for acute and chronic alcohol effects on sleep architecture and sleep electroencephalogram, evidence for tolerance with repeated administration, and possible underlying neurochemical mechanisms for alcohol's effects on sleep. Also discussed are sex differences as well as effects of alcohol on sleep homeostasis and circadian regulation. Evidence for the role of sleep disruption as a risk factor for developing alcohol dependence is discussed in the context of research conducted in adolescents. The utility of sleep-evoked potentials in the assessment of the effects of alcoholism on sleep and the brain and in abstinence-mediated recovery is also outlined. The chapter concludes with a series of questions that need to be answered to determine the role of sleep and sleep disturbance in the development and maintenance of problem drinking and the potential beneficial effects of the treatment of sleep disorders for maintenance of abstinence in alcoholism. © 2014 Elsevier B.V.

Alcohol-Induced Histone Acetylation Reveals a Gene Network Involved in Alcohol Tolerance

Sustained or repeated exposure to sedating drugs, such as alcohol, triggers homeostatic adaptations in the brain that lead to the development of drug tolerance and dependence. These adaptations involve long-term changes in the transcription of drug-responsive genes as well as an epigenetic restructuring of chromosomal regions that is thought to signal and maintain the altered transcriptional state. Alcohol-induced epigenetic changes have been shown to be important in the long-term adaptation that leads to alcohol tolerance and dependence endophenotypes. A major constraint impeding progress is that alcohol produces a surfeit of changes in gene expression, most of which may not make any meaningful contribution to the ethanol response under study. Here we used a novel genomic epigenetic approach to find genes relevant for functional alcohol tolerance by exploiting the commonalities of two chemically distinct alcohols. In Drosophila melanogaster, ethanol and benzyl alcohol induce mutual cross-tolerance, indicating that they share a common mechanism for producing tolerance. We surveyed the genome-wide changes in histone acetylation that occur in response to these drugs. Each drug induces modifications in a large number of genes. The genes that respond similarly to either treatment, however, represent a subgroup enriched for genes important for the common tolerance response. Genes were functionally tested for behavioral tolerance to the sedative effects of ethanol and benzyl alcohol using mutant and inducible RNAi stocks. We identified a network of genes that are essential for the development of tolerance to sedation by alcohol. PMID:24348266

This study used a case-control female sample to test psychiatric mediators and genetic moderators of the effect of sexual abuse on later alcohol dependence. The study also tested differences between alcohol dependent women with or without a history of sexual abuse on variables that might affect treatment planning. A case-control design compared 192 treatment-seeking alcohol dependent women with 177 healthy population controls. All participants were assessed for alcohol-related behaviors, sexual abuse history, psychiatric problems, and personality functioning. Markers were genotyped in the CRHR1, MAO-A and OPRM1 genes. The association of sexual abuse with alcohol dependence was limited to the most severe category of sexual abuse involving anal or vaginal penetration. Of the five psychiatric disorders tested, anxiety, anorexia nervosa, and bulimia met criteria as potential mediators of the abuse-alcohol dependence association. Severe sexual abuse continued to have an independent effect on alcohol dependence status even after accounting for these potential mediators. None of the candidate genetic markers moderated the association between sexual abuse and alcohol dependence. Of alcohol dependent participants, those with a history of severe abuse rated higher on alcoholism severity, and psychiatric comorbidities. Sexual abuse is associated with later alcohol problems directly as well as through its effect on psychiatric problems. Treatment-seeking alcohol dependent women with a history of abuse have distinct features as compared to other alcohol dependent women. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Modulation of alcohol preference by NMDA antagonists in male rats.
Lamblin, F; Deuceuninck, D; De Witte, P
1993-11-01
Chronic alcoholization by alcohol inhalation was used to study the properties of magnesium, a non-competitive NMDA receptor antagonist, and CGP 39551, a competitive NMDA receptor antagonist, on behavioural dependence as estimated by the free-choice paradigm [alcohol 10% (v/v) vs. water], on the hypermotility after alcohol withdrawal, and finally on the cortical vascularization. The first experimental group received the drugs per os during the whole alcoholization period. Magnesium (20 mg/kg/day) decreased the alcohol dependence while CGP 39551 (5 and 10 mg/kg/day) increased, in a dose-dependent manner, the dependence to alcohol. A second group of animals received the same drugs at the same dosages, not simultaneously during chronic alcoholization, but immediately after alcoholization in one shot i.p. injection. In this case, rats receiving 5 mg/kg CGP 39551 never showed any dependence towards alcohol, while 10 mg/kg CGP 39551 or 20 mg/kg magnesium prolonged the number of days of alcohol dependence. These results thus indicate the close interaction between NMDA receptor function and dependence for alcohol. Magnesium had no effects on hypermotility, while CGP 39551-treated animals presented a decrease in the hypermotility observed after alcohol withdrawal. Neither drug affected the hypervascularization accompanying the chronic alcoholization.

In this paper, an evaluation of Cloninger's typology of alcohol abuse in personality, psychopathology and personality disorders is carried out. The sample consisted of 158 alcoholics in treatment (56 Type I alcohol-dependent patients and 102 Type II alcohol-dependent patients). All subjects were assessed with diverse assessment tools related to personality (Impulsiveness Scale, Sensation Seeking Scale and STAI), psychopathology (SCL-90-R, BDI and Inadaptation Scale) and personality disorders (IPDE). The main findings were that Type II alcohol-dependent patients were more impulsive and sensation-seeking and they displayed more hostility and emotional distress than Type I alcohol-dependent patients. Personality disorders were not so prevalent in the case of Type I alcohol-dependent patients. The most specific personality disorders for Type II alcohol-dependent patients were narcissistic and paranoid. The implications of this study for further research are commented on.
Obtaining the Optimal Dose in Alcohol Dependence Studies

In alcohol dependence studies, the treatment effect at different dose levels remains to be ascertained. Establishing this effect would aid us in identifying the best dose that has satisfactory efficacy while minimizing the rate of adverse events. We advocate the use of dose-finding methodology that has been successfully implemented in the cancer and HIV settings to identify the optimal dose in a cost-effective way. Specifically, we describe the continual reassessment method (CRM), an adaptive design proposed for cancer trials to reconcile the needs of dose-finding experiments with the ethical demands of established medical practice. We are applying adaptive designs for identifying the optimal dose of medications for the first time in the context of pharmacotherapy research in alcoholism. We provide an example of a topiramate trial as an illustration of how adaptive designs can be used to locate the optimal dose in alcohol treatment trials. It is believed that the introduction of adaptive design methods will enable the development of medications for the treatment of alcohol dependence to be accelerated. PMID:23189064
Recent Advances in Nicotinic Receptor Signaling in Alcohol Abuse and Alcoholism.
Rahman, Shafiqur; Engleman, Eric A; Bell, Richard L
2016-01-01
Alcohol is the most commonly abused legal substance and alcoholism is a serious public health problem. It is a leading cause of preventable death in the world. The cellular and molecular mechanisms of alcohol reward and addiction are still not well understood. Emerging evidence indicates that unlike other drugs of abuse, such as nicotine, cocaine, or opioids, alcohol targets numerous channel proteins, receptor molecules, and signaling pathways in the brain. Previously, research has identified brain nicotinic acetylcholine receptors (nAChRs), a heterogeneous family of pentameric ligand-gated cation channels expressed in the mammalian brain, as critical molecular targets for alcohol abuse and dependence. Genetic variations encoding nAChR subunits have been shown to increase the vulnerability to develop alcohol dependence. Here, we review recent insights into the rewarding effects of alcohol, as they pertain to different nAChR subtypes, associated signaling molecules, and pathways that contribute to the molecular mechanisms of alcoholism and/or comorbid brain disorders. Understanding these cellular changes and molecular underpinnings may be useful for the advancement of brain nicotinic-cholinergic mechanisms, and will lead to a better translational and therapeutic outcome for alcoholism and/or comorbid conditions.

Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) are the principal enzymes responsible for metabolism of ethanol. Both ADH and ALDH exhibit genetic polymorphisms among racial populations. Functional variant alleles ADH1B*2 and ALDH2*2 have been consistently replicated to show protection against developing alcohol dependence. Multiple logistic regression analyses suggest that ADH1B*2 and ALDH2*2 may independently influence the risk for alcoholism. It has been well documented that homozygosity of ALDH2*2 almost fully protects against developing alcoholism and that the heterozygosity only affords a partial protection to varying degrees. Correlations of blood ethanol and acetaldehyde concentrations, cardiovascular hemodynamic responses, and subjective perceptions have been investigated in men with different combinatorial ADH1B and ALDH2 genotypes following challenge with ethanol for a period of 130 min. The pharmacokinetic and pharmacodynamic consequences indicate that acetaldehyde, rather than ethanol, is primarily responsible for the observed alcohol sensitivity reactions, suggesting that the full protection by ALDH2*2/*2 can be ascribed to the intense unpleasant physiological and psychological reactions caused by persistently elevated blood acetaldehyde after ingesting a small amount of alcohol and that the partial protection by ALDH2*1/*2 can be attributed to a faster elimination of acetaldehyde and the lower accumulation in circulation. ADH1B polymorphism does not significantly contribute to buildup of the blood acetaldehyde. Physiological tolerance or innate insensitivity to acetaldehyde may be crucial for development of alcohol dependence in alcoholics carrying ALDH2*2.

Hazardous alcohol consumption is a pattern of consumption that leads to a higher risk of harmful consequences either for the user or for others. This pattern of alcohol consumption has been linked to risky behaviors, accidents, and injuries. Individuals with hazardous alcohol consumption do not necessarily present alcohol dependence; thus, a study of particular neurophysiological correlates of this alcohol consumption pattern needs to be carried out in nondependent individuals. Here, we carried out a quantitative electroencephalography analysis in health sciences university students with hazardous alcohol consumption, but not alcohol dependence (HAC), and control participants without hazardous alcohol consumption or alcohol dependence (NHAC). We analyzed Absolute Power (AP), Relative Power (RP), and Mean Frequency (MF) for beta and theta frequency bands under both eyes closed and eyes open conditions. We found that participants in the HAC group presented higher beta AP at centroparietal region, as well as lower beta MF at frontal and centroparietal regions in the eyes closed condition. Interestingly, participants did not present any change in theta activity (AP, RP, or MF), whereas previous reports indicate an increase in theta AP in alcohol-dependent individuals. Our results partially resemble those found in alcohol-dependent individuals, although are not completely identical, suggesting a possible difference in the underlying neuronal mechanism behind alcohol dependence and hazardous alcohol consumption. Similarities could be explained considering that both hazardous alcohol consumption and alcohol dependence are manifestations of behavioral disinhibition.

Background Alcohol problems are a major health issue in Nepal and remain under diagnosed. Increase in consumption are due to many factors, including advertising, pricing and availability, but accurate information is lacking on the prevalence of current alcohol use disorders. The AUDIT (Alcohol Use Disorder Identification Test) questionnaire developed by WHO identifies individuals along the full spectrum of alcohol misuse and hence provides an opportunity for early intervention in non-specialty settings. This study aims to validate a Nepali version of AUDIT among patients attending a university hospital and assess the prevalence of alcohol use disorders along the full spectrum of alcohol misuse. Methods This cross-sectional study was conducted in patients attending the medicine out-patient department of a university hospital. DSM-IV diagnostic categories (alcohol abuse and alcohol dependence) were used as the gold standard to calculate the diagnostic parameters of the AUDIT. Hazardous drinking was defined as self reported consumption of ≥21 standard drink units per week for males and ≥14 standard drink units per week for females. Results A total of 1068 individuals successfully completed the study. According to DSM-IV, drinkers were classified as follows: No alcohol problem (n=562; 59.5%), alcohol abusers (n= 78; 8.3%) and alcohol dependent (n=304; 32.2%). The prevalence of hazardous drinker was 67.1%. The Nepali version of AUDIT is a reliable and valid screening tool to identify individuals with alcohol use disorders in the Nepalese population. AUDIT showed a good capacity to discriminate dependent patients (with AUDIT ≥11 for both the gender) and hazardous drinkers (with AUDIT ≥5 for males and ≥4 for females). For alcohol dependence/abuse the cut off values was ≥9 for both males and females. Conclusion The AUDIT questionnaire is a good screening instrument for detecting alcohol use disorders in patients attending a university hospital. This study also reveals a very high prevalence of alcohol use disorders in Nepal. PMID:23039711

The highest consumption levels of alcohol are found in the developed world, mostly the Northern Hemisphere. After a slight decrease at the beginning of the 1990s, alcohol use in the European Region increased with an average adult per capita consumption amounting to 12.5 litres of pure alcohol per capita for the year 2009. In France, adult consumption was 12.7 litres of pure alcohol per capita for the year 2009, and it is estimated that 1.5 to 2 million of adults are alcohol-dependent (4-5% of the adult population) and 5 million are excessive drinkers. The harmful use of alcohol is one of the world's leading health risks. Alcohol is the direct cause of more than 30 diseases and a causal factor in more than 60 major types of diseases and injuries, resulting in approximately 2.5 million deaths each year. Approximately 4% of all deaths worldwide and 4.5% (7.4% for men and 1.4% for women) of the global burden of disease and injury are attributable to alcohol. In 2004 in the EU, 15.2% of all disability-adjusted life years (DALYs) in men and 3.9% of all DALYs in women were lost due to alcohol. While the impact of alcohol consumption and dependence on mortality and disease is substantial, there are also many psychosocial consequences, including violence, family problems, child neglect and abuse, absenteeism and lost productivity in the workplace. This means that alcohol consumption and dependence have sizable impacts on many people other than the drinker. These effects add up to a staggering number of alcohol-attributable social costs, which can be estimated at € 155.8 billion a year in Europe. Despite all these consequences, many individuals with alcohol use disorders remain untreated although effective treatments exist. From 37 community-based psychiatric epidemiology studies that used standardized diagnostic instruments and included data on the percentage of individuals receiving care for alcohol abuse or dependence, the median rate of untreated cases of these disorders was calculated across the studies. Alcohol abuse and dependence had the widest treatment gap at 78.1% worldwide, and 92% in Europe. In this context, healthcare systems must adapt to meet the needs of patients who currently do not receive specialized care. Copyright © 2014 L’Encéphale, Paris. Published by Elsevier Masson SAS.

Glutamate decarboxylase (GAD), the rate-limiting enzyme in the synthesis of gamma-aminobutyric acid (GABA), may be involved in the development of alcoholism. This study examined the possible roles of the genes that code for 2 forms of GAD (GAD1 and GAD2) in the development of alcoholism. An association study was conducted among 140 male alcoholic subjects meeting the DSM-III-R criteria for alcohol dependence and 146 controls recruited from the Han Taiwanese in community and clinical settings. Psychiatric assessment of drinking conditions was conducted using a Chinese version of the Schedules for Clinical Assessment in Neuropsychiatry. The SHEsis and Haploview programs were used in statistical analyses. Nine single-nucleotide polymorphisms (SNPs) at the GAD1 gene were valid for further statistics. Between alcoholic subjects and controls, significant differences were found in genotype distributions of SNP1 (p=0.000), SNP2 (p=0.015), SNP4 (p=0.015), SNP5 (p=0.031), SNP6 (p=0.012), and SNP8 (p=0.004) and in allele distributions of SNP1 (p=0.001), SNP2 (p=0.009), and SNP8 (p=0.009). Permutation tests of SNP1, SNP2, and SNP8 demonstrated significant differences in allele frequencies but not in 2 major haplotype blocks. Three valid SNPs at the GAD2 gene demonstrated no associations with alcoholism. Further permutation tests in the only 1 haplotype block or individual SNPs demonstrated no significant differences. This is the first report indicating a possible significant role of the GAD1 gene in the development of alcohol dependence and/or the course of alcohol withdrawal and outcome of alcoholism.

Individuals with alcohol-dependent parents show an elevated risk of developing alcohol-related problems themselves. Modulations of the mesolimbic reward circuit have been postulated as a pre-existing marker of alcoholism. We tested whether a positive family history of alcoholism is correlated with ventral striatum functionality during a reward task. All participants performed a modified version of the monetary incentive delay task while their brain responses were measured with functional magnetic resonance imaging. We compared 206 healthy adolescents (aged 13-15) who had any first- or second-degree relative with alcoholism to 206 matched controls with no biological relative with alcoholism. Reward anticipation as well as feedback of win recruited the ventral striatum in all participants, but adolescents with a positive family history of alcoholism did not differ from their matched peers. Also we did not find any correlation between family history density and reward anticipation or feedback of win. This finding of no differences did not change when we analyzed a subsample of 77 adolescents with at least one parent with alcohol use disorder and their matched controls. Because this result is in line with another study reporting no differences between children with alcohol-dependent parents and controls at young age, but contrasts with studies of older individuals, one might conclude that at younger age the effect of family history has not yet exerted its influence on the still developing mesolimbic reward circuit. © 2014 Society for the Study of Addiction.
Drinking correlates of DSM-IV alcohol use disorder diagnostic orphans in college students.
Hagman, Brett T; Cohn, Amy M
2012-01-01
One major limitation of the DSM-IV criteria for alcohol abuse and dependence is that a cluster of individuals who endorse a subthreshold number of dependence criteria and no abuse criteria do not receive a formal diagnosis; despite elevated risk for alcohol-related problems relative to those with an abuse diagnosis. These individuals have been referred to as diagnostic orphans. The primary aim of this study was to examine alcohol use correlates of a group of diagnostic orphans in a sample of 396 nontreatment seeking college students who reported drinking on at least one occasion in the last 90 days. DSM-IV criteria were assessed using a modified version of the Composite International Diagnostic Interview-Substance Abuse Module (CIDI-SAM). Diagnostic orphans represented 34.1% (n = 135) of the original sample who did not receive a formal diagnosis; with the most frequently endorsed dependence criteria being tolerance and drinking larger/longer amounts than intended. Diagnostic orphans reported a range of alcohol-related negative consequences and reported greater frequencies of social and enhancement drinking motives in comparison to coping motives. They were similar to alcohol abusers and dissimilar to those with dependence or those without a diagnosis on alcohol consumption, alcohol problem severity, drinking motives and restraint variables. The present findings indicate that diagnostic orphans in college students represent a distinct group of drinkers who may be at risk for the development of alcohol use disorders and may be in need of intervention, given their similarity to those with an abuse diagnosis. Prevention and intervention efforts across college campuses should target this group to prevent escalation of alcohol problem severity. Copyright © American Academy of Addiction Psychiatry.

PURPOSE Alcohol dependence, frequently seen in medical settings, is a major problem that affects the health and well-being of many individuals and their families. The purpose of this study was to examine the relationship between treatment outcomes and patient and clinician factors specifically associated with a medically oriented intervention given for the treatment of alcohol dependence. The intervention was developed for the National Institute on Alcohol Abuse and Alcoholism–sponsored COMBINE Study, a randomized controlled trial combining 2 medications, naltrexone and acamprosate, with Medical Management, with or without specialty alcohol treatment. METHODS We examined the effect of patient adherence to treatment (number of Medical Management visits, total minutes in treatment, alliance or therapeutic relationship with the clinician, patient satisfaction with treatment, and clinician adherence to the Medical Management protocol) on abstinence from alcohol, amount of heavy drinking, and clinical improvement during treatment. RESULTS More Medical Management visits attended and less total time spent in Medical Management treatment was associated with more days of abstinence from alcohol, reductions in heavy alcohol drinking, and a higher likelihood of clinical improvement. The patients’ positive perceptions of their alliance with their clinician and their satisfaction with treatment was significantly associated with more days of abstinence from alcohol during treatment. Two clinician factors clinician confidence in the Medical Management treatment and flexibility in delivering Medical Management were also associated with better patient outcomes. CONCLUSIONS Medically trained clinicians with minimal specialty training in alcohol dependence treatments were able to deliver a brief and effective medication management intervention that was designed to be consistent with primary care practice.

[Maternal alcoholism and its impact on child health].
Sivolap, Y P
2015-01-01
Maternal alcoholism hinders the normal development of child and threatens his mental and physical health due to three factors: the hereditary transmission of predisposition to alcohol abuse; alcohol consumption during pregnancy; adverse family environment. The children of mothers suffering from alcoholism revealed are characterized by increased risk of depression, anxiety and other mental disorders, including alcohol and substance dependence. The adverse impact of maternal alcoholism (or, to speak more widely, parents' alcoholism) on the child health requires special preventive and treatment programs for both parents and children. Separation from the mother (even if the mother is addicted to alcohol) seriously injures the child, and therefore treatment programs for alcohol abusing women should be focused on the possible continuation of the parental rights of patients.

Epidemiological data show that in women, alcohol has a beneficial effect by increasing insulin sensitivity but also a deleterious effect by increasing breast cancer risk. These effects have not been shown concurrently in an animal model of breast cancer. Our objective is to identify a mouse model of breast cancer whereby alcohol increases insulin sensitivity and promotes mammary tumorigenesis. Our results from the glucose tolerance test and the homeostasis model assessment show that alcohol consumption improved insulin sensitivity. However, alcohol-consuming mice developed larger mammary tumors and developed them earlier than water-consuming mice. In vitro results showed that alcohol exposure increased the invasiveness of breast cancer cells in a dose-dependent manner. Thus, this animal model, an in vitro model of breast cancer, may be used to elucidate the mechanism(s) by which alcohol affects breast cancer. PMID:20202743

To examine the association between work characteristics and the risk of alcohol dependence across different employment types and occupations, including the pattern of alcohol consumption in the form of energy drinks and its association with alcohol dependence. A total of 13,501 men and 8584 women participated in a national survey in Taiwan. Alcohol dependence was defined as ≥2 points in the CAGE questionnaire. A self-administered questionnaire recorded drinking behaviors, consumption of alcoholic energy drinks, employment type, occupation and a number of psychosocial work stressors, namely job demands, job control, employment security and workplace justice. Of the total, 9.4% of men and 0.8% of women were CAGE-positive, and 6.0% of men and 0.7% of women regularly consumed alcoholic energy drinks. In male and female regular consumers of alcoholic energy drinks, 38.7 and 23.3%, respectively, were alcohol-dependent. Multivariate regression analyses showed that male employees in manual skilled occupations, with lower workplace justice, having weekly working hours <40 h and on piece-rated or time-based pay systems were at higher risks of alcohol dependence. Certain occupational groups and workers with adverse psychosocial work characteristics should be targets for prevention of alcohol dependence. Alcoholic energy drink consumption should be taken into consideration while studying alcohol dependence in the work population in Taiwan.

Ethnic and cultural differences in patterns of alcohol use disorders must be understood in order to address improvement in prevention of such disorders and accessibility to health care services. The purpose of this study was to evaluate factors that influence the utilization of medical and mental health services among alcohol-dependent and non-alcohol-dependent African Americans. A cohort of 454 African Americans was evaluated. Alcohol-dependent participants were recruited from various inpatient treatment facilities in the Washington, DC, metropolitan area and through advertisement and word of mouth. Non-alcohol-dependent participants were recruited by advertisements. Each participant was administered the Semi-Structured Assessment for the Genetics of Alcoholism to assess alcohol dependency and the Family History Assessment module to access family history of alcoholism. Xl Test and analysis of variance were used to analyze the data. Alcohol dependence was more prevalent among men, those with lower income, those with less education, and they utilized mental health counseling as opposed to medical-based therapy. Increased reports of medical conditions such as migraine (p<.001), loss of consciousness (p=.001), and sexually transmitted diseases: (p<.001) were also associated with alcohol dependency. Other factors, including visits to inpatient treatment programs, were directly related to incidence of alcohol dependency regardless of gender status (p<.001). This study suggests an association exists among alcohol dependence, medical conditions, health care, and mental care utilization among African Americans. Future research may benefit from investigating if an association exists between alcohol use disorders and health care utilization for other ethnic groups.

Extensive evidence suggests the role of oxidative stress in autism and other neurodevelopmental disorders. In this study, we investigated whether methylmercury (MeHg) and/or alcohol exposure has deleterious effects in Drosophila melanogaster (fruit flies). A diet containing different concentrations of MeHg in Drosophila induced free radical generation and increased lipid peroxidation (markers of oxidative stress) in a dose-dependent manner. This effect of MeHg on oxidative stress was enhanced by further exposure to alcohol. It was observed that alcohol alone could also induce free radical generation in flies. After alcohol exposure, MeHg did not affect the immobilization of flies, but it increased the recovery time in a concentration-dependent manner. MeHg significantly inhibited the activity of alcohol dehydrogenase (ADH) in a dose-dependent manner. Linear regression analysis showed a significant negative correlation between ADH activity and recovery time upon alcohol exposure in the flies fed a diet with MeHg. This relationship between ADH activity and recovery time after alcohol exposure was confirmed by adding 4-methyl pyrazole (an inhibitor of ADH) to the diet for the flies. These results suggest that consumption of alcohol by pregnant mothers who are exposed to MeHg may lead to increased oxidative stress and to increased length of time for alcohol clearance, which may have a direct impact on the development of the fetus, thereby increasing the risk of neurodevelopmental disorders.

To observe the relationship between alcohol dependence and new detected hypertension in adult residents of Xuzhou city. Participants were sampled by stratified multi-stage randomly cluster sampling method from February 2013 to June 2013 among permanent residents aged 18 and more in Xuzhou city. The alcohol dependence was defined with Michigan Alcoholism Screening Test (MAST). Other information was obtained by questionnaire. Spearman correlation analysis and multivariate logistic regression analysis were performed to identify the relationship between alcohol dependence and new detected hypertension. The alcohol dependence rate was 11.56% on the whole cohort (n=36 157), and 22.02%(3 854/17 501) for male and 1.74%(324/18 656) for female(P<0.01). The new detected hypertension rate was 9.46%(3 422/36 157) in the whole cohort. The new detected hypertension rate increased in proportion with the severity of alcohol dependence (P<0.01). Spearman correlation analysis showed that alcohol dependence was positively correlated with systemic blood pressure(r=0.071, P<0.01) and diastolic blood pressure (r=0.077, P<0.01). After adjusting for gender, age, marital status, body mass index, smoking status, physical activity level, educational level, income level and region, multivariate logistic regression analysis showed that alcohol dependence was an independent risk factor for hypertension (low alcohol dependence: OR=1.44, 95%CI 1.14-1.81, P<0.01; light alcohol dependence: OR=1.35, 95%CI 1.11-1.64, P<0.01; medium alcohol dependence: OR=1.83, 95%CI 1.40-2.41, P<0.01). The alcohol dependence is an independent risk factor for new detected hypertension in adult residents of Xuzhou city. Intensive hypertension prevention and treatment strategies should be performed on this population based on our results.

The continuous two bottle choice test is the most common measure of alcohol consumption but there is remarkably little information about the development of tolerance or dependence with this procedure. We showed that C57BL/6JxFVB/NJ and FVB/NJxC57BL/6J F1 hybrid mice demonstrate greater preference for and consumption of alcohol than either parental strain. In order to test the ability of this genetic model of high alcohol consumption to produce neuroadaptation, we examined development of alcohol tolerance and dependence after chronic self-administration using a continuous access two-bottle choice paradigm. Ethanol-experienced mice stably consumed about 16–18 g/kg/day of ethanol. Ethanol-induced withdrawal severity was assessed (after 59 days of drinking) by scoring handling-induced convulsions; withdrawal severity was minimal and did not differ between ethanol-experienced and -naïve mice. After 71 days of drinking, the rate of ethanol clearance was similar for ethanol-experienced and -naïve mice. After 77 days of drinking, ethanol-induced loss of righting reflex (LORR) was tested daily for 5 days. Ethanol-experienced mice had a shorter duration of LORR. For both ethanol-experienced and -naïve mice, blood ethanol concentrations taken at gain of righting reflex were greater on day 5 than on day 1, indicative of tolerance. After 98 days of drinking, ethanol-induced hypothermia was assessed daily for 3 days. Both ethanol-experienced and –naïve mice developed rapid and chronic tolerance to ethanol-induced hypothermia, with significant group differences on the first day of testing. In summary, chronic, high levels of alcohol consumption in F1 hybrid mice produced rapid and chronic tolerance to both the sedative/hypnotic and hypothermic effects of ethanol; additionally, a small degree of metabolic tolerance developed. The development of tolerance supports the validity of using this model of high alcohol consumption in genetic studies of alcoholism. PMID:23313769

Objective The lifetime prevalence of alcohol dependence in South Korea remains higher than other countries. The aim of our study is to identify factors associated with remission from alcohol dependence. Methods Data from the Korean Epidemiological Catchment Area-Replication (KECA-R) study were used in our study. The Korean version of the Composite International Diagnostic Interview 2.1 (K-CIDI 2.1) was administered. Remission was defined as having no symptom of alcohol dependence for 12 months or longer at the time of the interview. Demographic and clinical variables putatively associated with remission from alcohol dependence were examined by t-test, chi-square-test and logistic regression analysis. Results The lifetime prevalence rate of alcohol dependence was 7.0%. Among them, 3.2% of the subjects were diagnosed with active alcohol dependence in the previous 12 months, and 3.8% were found to be in remission. Subjects in 35- to 44-year-old group, not living with partner group, and lower level of educational attainment group were more likely to be in the active alcohol dependence state. Of the comorbid mental disorders, dysthymia, anxiety disorder, nicotine use, and nicotine dependence were more common among the actively alcohol-dependent subjects. Conclusion There is considerable level of recovery from alcohol dependence. Attention to factors associated with remission from alcohol dependence may be important in designing more effective treatment and prevention programs in this high-risk population. PMID:26207123
Alcohol Dependence, Mortality, and Chronic Health Conditions in a Rural Population in Korea

To determine the effects of excessive drinking and alcohol dependency on mortality and chronic health problems in a rural community in South Korea, this study represents a nested case-control study. In 1998, we conducted the Alcohol Dependence Survey (ADS), a population survey of a village in Korea. To measure the effects of alcohol on chronic health conditions and mortality over time, in 2004, we identified 290 adults from the ADS sample (N=1,058) for follow-up. Of those selected, 145 were adults who had alcohol problems, either alcohol dependence as assessed in the ADS by the Severity of Alcohol Dependence Questionnaire (N=59), or excessive drinking without dependency (N=86). Further 145 nondrinkers were identified, matching those with alcohol problems in age and sex. We revisited the village in 2004 and completed personal interviews with them. In multivariate logistic regressions, the rates of mortality and morbidity of chronic health conditions were three times greater for alcohol dependents compared with the rate for nondrinkers. Importantly, however, excessive drinking without dependency was not associated with the rates of either mortality or morbidity. Future investigations would benefit by attending more specifically to measures for alcohol dependence as well as measures for alcohol consumption. PMID:18303191

Disturbed sleep and a family history of alcohol dependence (AD) are risk factors for developing AD, yet the underlying relationship between them is unclear among individuals with AD. Understanding these inherited associations will help us not only identify risk for development of these comorbid disorders, but also individualize treatment at this interface. We evaluated whether a first-degree family history of AD (FH+) was a risk factor for sleep continuity disturbance in patients with AD. We also evaluated whether alcohol use or mood disturbance moderated the relationship between FH and sleep. We analyzed cross-sectional baseline data from an alcohol clinical trial in a sample of individuals with AD (N = 280). Their family history of AD among nuclear family members, sleep complaints, alcohol use (over the last 90 days), and mood disturbance were assessed using the Family History Interview for Substance and Mood Disorders, Medical Outcomes Study Sleep Scale, Time Line Follow-Back Interview, and Profile of Mood States-Short Form, respectively. A FH + status (65% of subjects) was significantly associated with lower model estimated mean sleep adequacy (β = - 7.05, p = 0.02) and sleep duration (β = - 0.38, p = 0.04) scale scores. FH was not associated with sleep disturbance scale. No significant moderating effect involving alcohol use or mood disturbance was seen. Family history of AD is a unique risk factor for sleep complaints in AD. Non-restorative sleep and sleep duration may be noteworthy phenotypes to help probe for underlying genotypic polymorphisms in these comorbid disorders. Published by Elsevier B.V.

Substance use disorder is a serious health problem that tends to manifest in late adolescence. Attempting to influence targetable risk and protective factors holds promise for prevention and treatment. Survey data from 1253 college students (48.5% male, 26.9% non-White) were used to investigate the independent and combined effects of two prominent factors, sensation seeking and parental monitoring, on the probability of alcohol and/or cannabis dependence during the first year of college. In multivariate analyses that controlled for high school use, gender, race, mother's education, and importance of religion, retrospective reports by the student of parental behavior during the last year of high school indicated that higher levels of parental monitoring had a direct effect on reducing risk for alcohol dependence during the first year of college, but not on cannabis dependence. High levels of sensation seeking were associated with increased risk for both alcohol and cannabis dependence. No interaction effects were found. The results extend prior findings by highlighting influences of pre-college parental monitoring and sensation seeking on the probability of alcohol and/or cannabis dependence during the first year of college. The findings also suggest that these two factors are useful in identifying college students at high risk for alcohol and/or cannabis dependence. Copyright © 2012 Elsevier Ltd. All rights reserved.

Animal studies support the role of the dopamine D3 receptor (DRD3) in alcohol reinforcement or liking. Sustained voluntary alcohol drinking in rats has been associated with an upregulation of striatal DRD3 gene expression and selective blockade of DRD3 reduces ethanol preference, consumption, and cue-induced reinstatement. In vivo measurement of DRD3 in the living human brain has not been possible until recently owing to a lack of suitable tools. In this study, DRD3 status was assessed for the first time in human alcohol addiction. Brain DRD3 availability was compared between 16 male abstinent alcohol-dependent patients and 13 healthy non-dependent age-matched males using the DRD3-preferring agonist positron emission tomography (PET) radioligand [11C]PHNO with and without blockade with a selective DRD3 antagonist (GSK598809 60 mg p.o.). In striatal regions of interest, where the [11C]PHNO PET signal represents primarily DRD2 binding, no differences were seen in [11C]PHNO binding between the groups at baseline. However, baseline [11C]PHNO binding was higher in alcohol-dependent patients in hypothalamus (VT: 16.5±4 vs 13.7±2.9, p=0.040), a region in which the [11C]PHNO signal almost entirely reflects DRD3 availability. The reductions in regional receptor binding (VT) following a single oral dose of GSK598809 (60 mg) were consistent with those observed in previous studies across all regions. There were no differences in regional changes in VT following DRD3 blockade between the two groups, indicating that the regional fractions of DRD3 are similar in the two groups, and the increased [11C]PHNO binding in the hypothalamus in alcohol-dependent patients is explained by elevated DRD3 in this group. Although we found no difference between alcohol-dependent patients and controls in striatal DRD3 levels, increased DRD3 binding in the hypothalamus of alcohol-dependent patients was observed. This may be relevant to the development of future therapeutic strategies to treat alcohol abuse. PMID:24469594

Objective Ethnic and cultural differences in patterns of alcohol use disorders must be understood in order to address improvement in prevention of such disorders and accessibility to health care services. The purpose of this study was to evaluate factors that influence the utilization of medical and mental health services among alcohol-dependent and non alcohol–dependent African Americans. Method A cohort of 454 African Americans was evaluated. Alcohol-dependent participants were recruited from various inpatient treatment facilities in the Washington, DC, metropolitan area and through advertisement and word of mouth. Non–alcohol-dependent participants were recruited by advertisements. Each participant was administered the Semi-Structured Assessment for the Genetics of Alcoholism to assess alcohol dependency and the Family History Assessment module to access family history of alcoholism. χ2 Test and analysis of variance were used to analyze the data. Results Alcohol dependence was more prevalent among men, those with lower income, those with less education, and they utilized mental health counseling as opposed to medical-based therapy. Increased reports of medical conditions such as migraine (p < .001), loss of consciousness (p = .001), and sexually transmitted diseases (p < .001) were also associated with alcohol dependency. Other factors, including visits to inpatient treatment programs, were directly related to incidence of alcohol dependency regardless of gender status (p < .001). Conclusions This study suggests an association exists among alcohol dependence, medical conditions, health care, and mental care utilization among African Americans. Future research may benefit from investigating if an association exists between alcohol use disorders and health care utilization for other ethnic groups. PMID:23862295

Behavioral studies have shown an alcohol-approach bias in alcohol-dependent patients: the automatic tendency to faster approach than avoid alcohol compared with neutral cues, which has been associated with craving and relapse. Although this is a well-studied psychological phenomenon, little is known about the brain processes underlying automatic action tendencies in addiction. We examined 20 alcohol-dependent patients and 17 healthy controls with functional magnetic resonance imaging (fMRI), while performing an implicit approach-avoidance task. Participants pushed and pulled pictorial cues of alcohol and soft-drink beverages, according to a content-irrelevant feature of the cue (landscape/portrait). The critical fMRI contrast regarding the alcohol-approach bias was defined as (approach alcohol>avoid alcohol)>(approach soft drink>avoid soft drink). This was reversed for the avoid-alcohol contrast: (avoid alcohol>approach alcohol)>(avoid soft drink>approach soft drink). In comparison with healthy controls, alcohol-dependent patients had stronger behavioral approach tendencies for alcohol cues than for soft-drink cues. In the approach, alcohol fMRI contrast patients showed larger blood-oxygen-level-dependent responses in the nucleus accumbens and medial prefrontal cortex, regions involved in reward and motivational processing. In alcohol-dependent patients, alcohol-craving scores were positively correlated with activity in the amygdala for the approach-alcohol contrast. The dorsolateral prefrontal cortex was not activated in the avoid-alcohol contrast in patients vs controls. Our data suggest that brain regions that have a key role in reward and motivation are associated with the automatic alcohol-approach bias in alcohol-dependent patients.

Alcohol intake is strongly associated with hyperuricemia, which may cause gout. This study evaluated the risk of gout in patients with alcohol-related diseases and alcohol dependence syndrome. We used the Taiwan National Health Insurance Research Database (NHIRD) to conduct a nationwide population-based cohort study to assess the risk of gout and gout incidence in patients with alcohol-related diseases and alcohol dependence syndrome (as defined by the International Classification of Diseases, Ninth Revision). In the NHIRD records from 1998 to 2008, we identified 11,675 cases of alcohol-related diseases. The control group comprised 23,350 cases without alcohol-related diseases propensity score-matched (1 case: 2 controls) for age, age group, and sex. The results revealed that alcohol-related diseases were significantly associated with gout risk (adjusted hazard ratio 1.88; P<0.0001). Of the alcohol-related disease cases, 34.1% of the patients had alcohol dependence syndrome (males 34.8%; females 32.4%), and alcohol dependence was independently associated with gout occurrence (relative risk [RR] 2.01; P<0.0001). Severe alcohol-dependent patients (who were also the heavy benzodiazepines users), were associated with an increased risk of gout (RR 1.71 to 4.21, P≤0.0182). Physicians should be aware of the association between alcohol dependence syndrome and gout occurrence, and alcohol use assessment and measures to prevent alcohol dependence should be implemented in the integrative care for patients with gout.

Patients with a double diagnosis of alcohol dependence and phobic disorders are a common phenomenon in both alcohol and anxiety disorder clinics. If we are to provide optimum treatment we need to know more about the clinical characteristics of this group of comorbid patients. To answer the following questions. (1). What are the clinical characteristics of treatment-seeking alcohol-dependent patients with a comorbid phobic disorder? (2). Are alcohol dependence and other clinical characteristics of comorbid patients different from those of 'pure' alcohol-dependent patients? (3). Are the anxiety symptoms and other clinical characteristics of comorbid patients different from those of 'pure' phobic patients? Three groups of treatment-seeking patients were compared on demographic and clinical characteristics: alcohol dependent patients with a comorbid phobic disorder (n = 110), alcohol-dependent patients (n = 148) and patients with social phobia or agoraphobia (n = 106). In order to diagnose the comorbid disorders validly, the assessment took place at least 6 weeks after detoxification. Comorbid patients have high scores on depressive symptoms and general psychopathology: 25% of patients have a current and 52% a lifetime depressive disorder. The majority have no partner and are unemployed, they have a high incidence of other substance use (benzodiazepine, cocaine, cannabis) and a substantial proportion of comorbid patients have been emotionally, physically and sexually abused. They do not have a more severe, or different type of alcohol dependence or anxiety disorder than 'pure' alcohol-dependent patients and phobic patients respectively. Comorbid patients constitute a complex part of the treatment-seeking population in alcohol clinics and psychiatric hospitals. These findings should be taken into account when diagnosing and treating alcohol-dependent patients with a comorbid phobic disorder.

Background During the transition to alcohol and drug addiction, neuromodulator systems in the extended amygdala are recruited to mediate aspects of withdrawal and relapse via convergence on inhibitory GABA neurons in central amygdala (CeA). Methods This study investigated the role of neuropeptide Y (NPY) in excessive alcohol drinking by making rats dependent on alcohol via alcohol vapor inhalation. This study also utilized intracellular and whole-cell recording techniques to determine the effects of NPY on GABAergic inhibitory transmission in CeA, synaptic mechanisms involved in these NPY effects, and NPY interactions with alcohol in the CeA of alcohol-naïve and alcohol-dependent rats. Results Chronic NPY treatment blocked excessive operant alcohol-reinforced responding associated with alcohol dependence, as well as gradual increases in alcohol responding by intermittently tested non-dependent controls. NPY decreased baseline GABAergic transmission and reversed alcohol-induced enhancement of inhibitory transmission in CeA by suppressing GABA release via actions at presynaptic Y2 receptors. Conclusions These results highlight NPY modulation of GABAergic signaling in central amygdala as a promising pharmacotheraputic target for the treatment of alcoholism. GABA neurons in the CeA likely constitute a major point of convergence for neuromodulator systems recruited during the transition to alcohol dependence. PMID:21459365

Background Prazosin (PRZ, an α1-adrenergic receptor antagonist) and naltrexone (NTX, a non-specific opioid receptor antagonist) each decrease alcohol drinking when administered to rats selectively-bred for high voluntary alcohol drinking (alcohol-preferring, or “P”), and the combination of PRZ+NTX decreases alcohol drinking more effectively than does either drug alone. Since drug responsiveness can depend on history of alcohol drinking and dependence, we investigated whether various schedules of PRZ and NTX administration, alone or in combination, are effective in decreasing alcohol drinking in male P rats with a history of protracted voluntary alcohol drinking, dependence and repeated withdrawals closely resembling human alcoholism. Methods Male P rats became alcohol-dependent during 1 year of ad libitum 24 h/day access to food, water and 20% alcohol with repetitive temporary alcohol withdrawals. Four sequential studies then addressed effects of oral PRZ (2 mg/kg) and NTX (10 mg/kg), alone or together, on alcohol drinking during: 1) daily alcohol access with daily drug treatment, 2) intermittent alcohol access with daily drug treatment, 3) intermittent alcohol access with occasional drug treatment, and 4) post-deprivation reinstatement of alcohol access. Results The combination of PRZ+NTX consistently suppressed alcohol drinking during daily or intermittent alcohol access conditions and when drug treatment was either daily or occasional. PRZ+NTX was consistently more effective than either drug alone. The reduction in alcohol drinking was not due to sedation, motor effects or malaise. Conclusions Both daily and “as-needed” treatment with PRZ+NTX are highly effective in suppressing daily, intermittent and post-deprivation alcohol drinking in male P rats with a protracted history of alcohol dependence and repeated withdrawals. This drug combination may be especially effective for treating individuals with long histories of heavy alcohol abuse, dependence and repeated relapse, as commonly encountered in clinical practice.

Objective: Alcohol use problems are common during adolescence and can predict serious negative outcomes in adulthood, including substance dependence and psychopathology. The current study examines the notion that alcohol use problems are driven by polygenic influences and that genetic influences may indirectly affect alcohol use problems through multiple pathways of risk, including variations in personality. Method: We used a genome-wide approach to examine associations between genetic risk for alcohol use problems, personality dimensions, and adolescent alcohol use problems in two separate longitudinal population-based samples, the Finnish Twin Cohort (FinnTwin12) and the Avon Longitudinal Study of Parents and Children (ALSPAC). Participants were 1,035 young adults from FinnTwin12 and 3,160 adolescents from ALSPAC. Polygenic risk scores (PRS) were calculated for ALSPAC using genome-wide association results (on alcohol dependence symptoms as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) from FinnTwin12. A parallel multiple mediator model was tested to examine whether the association between PRS and alcohol use problems assessed at age 16 could be explained by variations in personality dimensions assessed at age 13, including sensation seeking and negative emotionality. Results: PRS were marginally predictive of age 16 alcohol use problems; this association was partially mediated by sensation seeking. Polygenic variation underlying risk for alcohol use problems may directly influence the effects of sensation seeking, which in turn influence the development of alcohol use problems in later adolescence. Conclusions: These findings contribute to the increasing evidence regarding the salience of sensation seeking during early adolescence as a potential constituent in the risk pathway underlying the development of alcohol use problems.

Background Interventions requiring abstinence from alcohol are neither preferred by nor shown to be highly effective with many homeless individuals with alcohol dependence. It is therefore important to develop lower-threshold, patient-centered interventions for this multimorbid and high-utilizing population. Harm-reduction counseling requires neither abstinence nor use reduction and pairs a compassionate style with patient-driven goal-setting. Extended-release naltrexone (XR-NTX), a monthly injectable formulation of an opioid receptor antagonist, reduces craving and may support achievement of harm-reduction goals. Together, harm-reduction counseling and XR-NTX may support alcohol harm reduction and quality-of-life improvement. Aims Study aims include testing: a) the relative efficacy of XR-NTX and harm-reduction counseling compared to a community-based, supportive-services-as-usual control, b) theory-based mediators of treatment effects, and c) treatment effects on publicly funded service costs. Methods This RCT involves four arms: a) XR-NTX+harm-reduction counseling, b) placebo+harm-reduction counseling, c) harm-reduction counseling only, and d) community-based, supportive-services-as-usual control conditions. Participants are currently/formerly homeless, alcohol dependent individuals (N=300). Outcomes include alcohol variables (i.e., craving, quantity/frequency, problems and biomarkers), health-related quality of life, and publicly funded service utilization and associated costs. Mediators include 10-point motivation rulers and the Penn Alcohol Craving Scale. XR-NTX and harm-reduction counseling are administered every 4 weeks over the 12-week treatment course. Follow-up assessments are conducted at weeks 24 and 36. Discussion If found efficacious, XR-NTX and harm-reduction counseling will be well-positioned to support reductions in alcohol-related harm, decreases in costs associated with publicly funded service utilization, and increases in quality of life among homeless, alcohol-dependent individuals.

Multiple dopamine receptors in the dopaminergic system may be prime candidates for genetic influence on alcohol abuse and dependence due to their involvement in reward and reinforcing mechanisms. Genetic polymorphisms in dopamine receptor genes are believed to influence the development and/or severity of alcoholism. To examine the genetic effects of the Dopamine Receptor D1 (DRD) gene family (DRD1-DRD5) in the Korean population, 11 polymorphisms in the DRD gene family were genotyped and analyzed in 535 alcohol-dependent subjects and 273 population controls. Although none of the polymorphisms of DRD1-5 genes were found to be associated with the risk of alcoholism, one 5' UTR polymorphism in the DRD1 (DRD1-48A>G) gene was significantly associated with severity of alcohol-related problem, as measured by the Alcohol Use Disorders Identification Test (AUDIT) in a gene dose-dependent manner, i.e., 24.37 (+/-8.19) among patients with -48A/A genotype, 22.37 (+/-9.49) among those with -48A/G genotype, and 17.38 (+/-8.28) among those with -48G/G genotype (P=0.002). The genetic effects of DRD1-48A>G were further analyzed with other phenotypes among alcohol-dependent subjects. Interestingly, the DRD1-48A>A genotype was also found to be associated with novelty seeking (NC), harm avoidance (HA), and persistence (P) (P =0.01, 0.02, and 0.003, respectively). The information derived from this study could be valuable for understanding the genetic factors involved in alcoholic phenotypes and genetic distribution of the DRD gene family, and could facilitate further investigation in other ethnic groups.

Excessive alcohol consumption has been linked to structural and functional brain changes associated with cognitive, emotional, and behavioral impairments. It has been suggested that neural processing in the reward system is also affected by alcoholism. The present study aimed at further investigating reward-based associative learning and reversal learning in detoxified alcohol-dependent patients. Twenty-one detoxified alcohol-dependent patients and 26 healthy control subjects participated in a probabilistic learning task using monetary and alcohol-associated rewards as feedback stimuli indicating correct responses. Performance during acquisition and reversal learning in the different feedback conditions was analyzed. Alcohol-dependent patients and healthy control subjects showed an increase in learning performance over learning blocks during acquisition, with learning performance being significantly lower in alcohol-dependent patients. After changing the contingencies, alcohol-dependent patients exhibited impaired reversal learning and showed, in contrast to healthy controls, different learning curves for different types of rewards with no increase in performance for high monetary and alcohol-associated feedback. The present findings provide evidence that dysfunctional processing in the reward system in alcohol-dependent patients leads to alterations in reward-based learning resulting in a generally reduced performance. In addition, the results suggest that alcohol-dependent patients are, in particular, more impaired in changing an established behavior originally reinforced by high rewards.

Past research has highlighted an important role of the autonomic nervous system in alcohol dependence and capacity for self-regulation. While previous studies have examined alcohol dependent inpatients, it remains unclear whether resting-state HRV, a potential psychophysiological marker of ones capacity for self-regulation, is related to craving in patients who currently consume alcohol. Thus, the aim of the present study was to determine whether HRV predicts alcohol craving in dependent individuals in the community. Resting-state HRV and alcohol craving, as indexed by the obsessive compulsive drinking scale, were assessed in 26 alcohol dependent outpatients. Results supported hypotheses indicating that HRV accounts for an additional 12.1% of the variance in craving after controlling for age, anxiety and levels of alcohol consumption. Here we show for the first time that resting-state HRV predicts craving in alcohol dependent outpatients. Results provide important new evidence for a role of the autonomic nervous system in the maintenance of dependence disorders. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Alcohol dependence causes physical, social, and moral harms and currently represents an important public health concern. According to the World Health Organization (WHO), alcoholism is the third leading cause of death worldwide, after tobacco consumption and hypertension. Recent epidemiologic studies have shown a growing trend in alcohol abuse among adolescents, characterized by the consumption of large doses of alcohol over a short time period. Since brain development is an ongoing process during adolescence, short- and long-term brain damage associated with drinking behavior could lead to serious consequences for health and wellbeing. Accumulating evidence indicates that alcohol impairs the function of different components of the melanocortin system, a major player involved in the consolidation of addictive behaviors during adolescence and adulthood. Here, we hypothesize the possible implications of melanocortins and glial cells in the onset and progression of alcohol addiction. In particular, we propose that alcohol-induced decrease in α-MSH levels may trigger a cascade of glial inflammatory pathways that culminate in altered gliotransmission in the ventral tegmental area and nucleus accumbens (NAc). The latter might potentiate dopaminergic drive in the NAc, contributing to increase the vulnerability to alcohol dependence and addiction in the adolescence and adulthood.

The genetic basis for the predisposition to alcoholic liver cirrhosis (ALC) remains unknown. Increasing evidence supports a role for the nuclear factor (NF)-kappaB, the NF-kappaB inhibitor alpha (NFKBIA), and the peroxisome proliferator-activated receptor (PPAR)-gamma in the pathogenesis of alcoholic liver disease, raising the possibility that common polymorphisms in genes encoding these molecules may confer susceptibility to ALC. The objective of this study was to analyze the relationship between common polymorphisms in NFKB1, NFKBIA, and PPARG2 genes and the presence of ALC. A total of 258 male alcoholics (161 without liver disease and 97 with ALC) and 101 healthy controls were genotyped for the -94ins/delATTG NFKB1, 3'-UTR+126G>A NFKBIA, and 34C>G PPARG2 polymorphisms. The association of these genetic variants with ALC was tested in alcoholic patients with alcohol abuse and alcohol dependence. A logistic regression analysis was further performed to analyze the model of inheritance. We found an association between the presence of the deletion allele in NFKB1 polymorphism and ALC in patients with alcohol dependence. We found no association between NFKBIA and PPARG2 polymorphisms and the presence of ALC. The deletion allele of the -94ins/del NFKB1 polymorphism could be associated with a higher risk of developing ALC through an increase in inflammation, as supported by previous data.
Preclinical studies of alcohol binge drinking

Binge drinking is prevalent and has serious biomedical consequences. In children, adolescents, and young adults, it is a prominent risk factor for later development of alcohol-use disorders. Many preclinical models have been employed to study the genetic risks for and biomedical consequences of alcohol drinking. However, these models historically did not result in blood-alcohol concentrations (BACs) exceding 80 mg%; this relatively modest level is the threshold that currently defines a binge session, according to the NIAAA and CDC. Nevertheless, in alcohol-dependent rodents, binge drinking has been well documented. Key neurobiological substrates localized to brain reward and stress systems have been identified. Studies of newer models of binge drinking without dependence are reviewed here. In these models, rodents, non-human primates, and flies will drink enough to reach high BACs. They often display observable signs of intoxication. The neurobiological consequences of these episodes of binge drinking without dependence are reviewed, preliminary evidence for roles for GABA, glutamate, opioid peptides, and corticotropin releasing factor are discussed, as is the need for more work to identify the antecedents and consequences of binge drinking in both animal models and humans.

Cognitive impairments in individuals with alcohol dependence may interfere with the progress of treatment and contribute to the progression of the disease. This study aimed to determine whether cognitive remediation (CR) therapy applied during treatment for alcohol dependence improves cognitive functioning in alcohol-dependent inpatients. A secondary aim was to evaluate whether the benefits of CR generalize to noncognitive clinically meaningful outcomes at the end of inpatient treatment. Forty-one alcohol-dependent patients entering inpatient treatment for alcohol dependence were randomly assigned to receive conventional treatment (n = 21) or an additional 12 sessions of computer-assisted CR focusing on cognitive enhancement in attention/executive function and memory domains (n = 20). Assessments of cognitive abilities in these domains as well as of psychological well-being and alcohol craving were conducted at baseline (at the beginning of inpatient treatment) and after CR (at the end of treatment). Results indicated that, relative to patients completing conventional treatment, those who received supplemental CR showed significant improvement in attention/executive function and memory domains, particularly in attention (alertness, divided attention), working memory, and delayed memory (recall). In addition, patients receiving CR during alcohol-dependence treatment showed significantly greater improvements in psychological well-being (Symptom Checklist-90-Revised) and in the compulsion aspect of craving (Obsessive Compulsive Drinking Scale-German version). CR during inpatient treatment for alcohol dependence is effective in improving cognitive impairments in alcohol-dependent patients. The benefits generalize to noncognitive outcomes, demonstrating that CR may be an efficacious adjunctive intervention for the treatment of alcohol dependence.

Genome-wide association studies (GWAS) have revealed many single nucleotide polymorphisms (SNPs) associated with complex traits. Although these studies frequently fail to identify statistically significant associations, the top association signals from GWAS may be enriched for true associations. We therefore investigated the association of alcohol dependence with 43 SNPs selected from association signals in the first two published GWAS of alcoholism. Our analysis of 808 alcohol-dependent cases and 1,248 controls provided evidence of association of alcohol dependence with SNP rs1614972 in the ADH1C gene (unadjusted p = 0.0017). Because the GWAS study that originally reported association of alcohol dependence with this SNP [1] included only men, we also performed analyses in sex-specific strata. The results suggest that this SNP has a similar effect in both sexes (men: OR (95%CI) = 0.80 (0.66, 0.95); women: OR (95%CI) = 0.83 (0.66, 1.03)). We also observed marginal evidence of association of the rs1614972 minor allele with lower alcohol consumption in the non-alcoholic controls (p = 0.081), and independently in the alcohol-dependent cases (p = 0.046). Despite a number of potential differences between the samples investigated by the prior GWAS and the current study, data presented here provide additional support for the association of SNP rs1614972 in ADH1C with alcohol dependence and extend this finding by demonstrating association with consumption levels in both non-alcoholic and alcohol-dependent populations. Further studies should investigate the association of other polymorphisms in this gene with alcohol dependence and related alcohol-use phenotypes. PMID:23516558

As executive dysfunctions frequently accompany alcohol dependence, we suggest that reports of executive dysfunction in alcoholics are actually due, in some case to a maternal history of alcohol misuse (MHA+). A history of maternal alcohol dependence increases the risk for prenatal alcohol exposure to unborn children. These exposures likely contribute to executive dysfunction in adult alcoholics. To assess this problem, we propose a case-comparison study of alcohol-dependent subjects with and without a MHA. Ten alcohol-dependent subjects, with a maternal history of alcoholism (MHA) and paternal history of alcoholism (PHA), were matched with 10 alcohol-dependent people with only a paternal history of alcoholism (PHA). Executive functions (cancellation, Stroop, and trail-making A and B tests) and the presence of a history of three mental disorders (attention deficit hyperactivity disorder, violent behavior while intoxicated, and suicidal behavior) were evaluated in both populations. Alcohol-dependent subjects with MHA showed a significant alteration in executive functions and significantly more disorders related to these functions than PHA subjects. The major measures of executive functioning deficit are duration on task accomplishment in all tests. Rates of ADHD and suicidality were found to be higher in MHA patients compared to the controls. A history of MHA, because of the high risk of PAE (in spite of the potential confounding factors such as environment) must be scrupulously documented when evaluating mental and cognitive disorders in a general population of alcoholics to ensure a better identification of these disorders. It would be helpful to replicate the study with more subjects.

Craving for alcohol and food has been studied in association with alcohol dependence and eating disorders, respectively. One subclass of the gamma-aminobutyric acid (GABA) receptor, 1519T>C GABA(A)alpha6 has been reported to be associated with both alcohol dependence and weight gain. In this study, we hypothesized that patients being treated for alcohol dependence would report decreased craving for alcohol, but an increased craving for food during a 4-week treatment period. We further hypothesized that the T allele of the 1519T>C GABA(A)alpha6 gene would modulate the extent of changes in craving for alcohol and food. This study included 98 male inpatients being treated for alcohol dependence. A 7-point visual analog scale was applied to evaluate relative levels of alcohol and food craving at baseline and again 4 weeks later. Body weight was also checked at the same periods. Genotyping of the 1519T>C SNP in GABA(A)alpha6 was carried out by restriction fragment length polymorphism. There were significant changes in craving for alcohol and food in all patients with alcohol dependence. During the treatment period, body weight increased in all patients with alcohol dependence. Changes in alcohol and food craving in T-allele carriers (CT + TT) of 1519T>C GABA(A)alpha6 were greater than those observed in CC homozygotes. In T-allele carriers, body weight significantly increased and the changes in weight showed a negative correlation with the change in the craving for alcohol and a positive correlation with the changes in craving for food. The current results suggest that in T-allele carriers the change in craving for alcohol during treatment for alcohol dependence is negatively associated with changes in craving for food. The T allele of the 1519T>C GABA(A)alpha6 gene may be one of the modulating factors associated with changes in craving for alcohol and food during treatment of patients with alcohol dependence.

Background Multiple studies have shown that genetic variation in the α-2 subunit of the GABA-A receptor (GABRA2) is associated with risk for alcohol dependence. Recent reports have suggested that GABRA2 may exert its influence on dependence through factors such as sensitivity to alcohol's intoxicating effects and that GABRA2 may also contribute to a common underlying genetic vulnerability to both alcohol and drug dependence. The present study tested for association between GABRA2 and alcohol dependence, smoking and illicit drug use within the Australian population. Methods We genotyped 11 single nucleotide polymorphisms within or flanking GABRA2 in 4597 subjects (34.6% males) from 2618 families comprising 814 monozygotic pairs, 1177 dizygotic pairs and 627 twins whose co-twin did not participate. Family-based association tests were conducted for binary and quantitative measures of alcohol dependence, smoking, cannabis and other illicit drug use. Results We observed evidence of association (p < 0.05) between multiple GABRA2 SNPs and quantitative measures of alcohol dependence, including symptom scores and principal component factor scores from the 9 criteria for DSM-IV alcohol dependence, in the opposite direction to that previously reported. In contrast, GABRA2 was not associated overall with dichotomous measure of alcohol dependence, nor with smoking, cannabis or illicit drug use. Conclusions The GABRA2 allelic associations found in clinical case-control studies have detectable but minor effects on DSM-defined alcohol dependence in the general community. Systematic comparisons of allelic effects on alcohol dependence in clinical cases and in the general community are required. PMID:18727688

This study examined whether the experiences of childhood or adolescent parental divorce/separation and parental alcohol problems affected the likelihood of offspring DSM-IV lifetime alcohol dependence, controlling for parental history of drug, depression, and antisocial behavior problems. Data were drawn from the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC), a nationally representative United States survey of 43,093 civilian non-institutionalized participants aged 18 and older, interviewed in person. Logistic regression models were used to calculate the main and interaction effects of childhood or adolescent parental divorce/separation and parental history of alcohol problems on offspring lifetime alcohol dependence, after adjusting for parental history of drug, depression, and antisocial behavior problems. Childhood or adolescent parental divorce/separation and parental history of alcohol problems were significantly related to offspring lifetime alcohol dependence, after adjusting for parental history of drug, depression, and antisocial behavior problems. Experiencing parental divorce/separation during childhood, even in the absence of parental history of alcohol problems, remained a significant predictor of lifetime alcohol dependence. Experiencing both childhood or adolescent parental divorce/separation and parental alcohol problems had a significantly stronger impact on the risk for DSM-IV alcohol dependence than the risk incurred by either parental risk factor alone. Further research is needed to better identify the factors that increase the risk for lifetime alcohol dependence among those who experience childhood or adolescent parental divorce/separation.

This paper introduces the Special Section: Pharmacotherapies for the Treatment of Alcohol Abuse and Dependence and provides a summary of patents targeting neurotransmitter systems not covered in the other four chapters. The World Health Organization notes that alcoholic-type drinking results in 2.5 million deaths per year, and these deaths occur to a disproportionately greater extent among adolescents and young adults. Developing a pharmacological treatment targeting alcohol abuse and dependence is complicated by (a) the heterogeneous nature of the disease(s), (b) alcohol affecting multiple neurotransmitter and neuromodulator systems, and (c) alcohol affecting multiple organ systems which in turn influence the function of the central nervous system. Presently, the USA Federal Drug Administration has approved three pharmacotherapies for alcoholism: disulfiram, naltrexone, and acamprosate. This chapter provides a summary of the following systems, which are not covered in the accompanying chapters; alcohol and acetaldehyde metabolism, opioid, glycinergic, GABA-A, neurosteroid, dopaminergic, serotonergic, and endocannabinoid, as well as patents targeting these systems for the treatment of alcoholism. Finally, an overview is presented on the use of pharmacogenetics and pharmacogenomics in tailoring treatments for certain subpopulations of alcoholics, which is expected to continue in the future.

Adolescents ages 10–15 experience dramatic changes in their biological, cognitive, emotional, and social development as well as in their physical and social environments. These include the physiological and psychological changes associated with puberty; further development of the brain; changes in family, peer, and romantic relationships; and exposure to new societal and cultural influences. During this period, many adolescents also begin to use alcohol. Alcohol use during adolescence has adverse effects on the body and increases the risk of alcohol dependence later in life. To better understand why some children drink whereas others do not, researchers are examining nonspecific and alcohol-specific factors that put adolescents at risk for, or which protect them from, early alcohol use and its associated problems. Nonspecific risk factors include certain temperamental and personality traits, family factors, and nonnormative development. Examples of nonspecific protective factors include certain temperamental characteristics, religiosity, and parenting factors (e.g., parental nurturance and monitoring). Among the most influential alcohol-specific risk and protective factors are a family history of alcoholism and the influences of siblings and peers, all of which shape an adolescent’s expectancies about the effects of alcohol, which in turn help determine alcohol use behaviors.

Alcohol dependence: international policy implications for prison populations.
Jones, Gail Yvonne; Hoffmann, Norman G

In light of the emphasis on drug abuse, this study explored the relative prevalence of substance use disorders among United Kingdom (UK) prison inmates in the context of findings from a general inmate population in the United States (US). The lead author of the report conducted a structured diagnostic interview with 155 new admissions to one of two prisons in the UK using the CAAPE (Comprehensive Addiction And Psychological Evaluation), a structured diagnostic interview, to ensure consistent assessments. The US sample consisted of 6,881 male inmates in a state prison system evaluated with an automated version of the SUDDS-IV (Substance Use Disorder Diagnostic Schedule-IV) interview. Alcohol dependence emerged as the most prevalent substance use disorder in both UK prisons and in the US sample. Relative frequencies of abuse and dependence for alcohol and other drugs revealed that dependence on a given substance was more prevalent than abuse ad defined by the current diagnostic criteria. Despite the emphasis on drugs in correctional populations, alcohol dependence appears to be the most prominent substance use disorder among the incarcerated in both the US and UK and must be considered in developing treatment programs and policy priorities.

When alcohol-dependent individuals are exposed to drinking-related cues, they exhibit psychophysiological reactivity such as changes in heart rate variability (HRV) and skin temperature. Moreover, such alcohol cue-reactivity may co-occur with attentional bias (AB) toward alcohol cues. In turn, stress may promote appetitive responses by exacerbating these autonomic and attentional factors. Although cue-reactivity paradigms have been used for decades to probe such automatic appetitive processes in persons with alcohol-use disorders, less is known about the attentional correlates of alcohol cue-reactivity. In this study, alcohol-dependent adults (N = 58) recruited from a residential treatment facility completed a spatial cueing task as a measure of alcohol AB and affect-modulated cue-reactivity protocol. Multiple linear regression analyses revealed that alcohol AB was significantly positively associated with parasympathetically mediated HRV and finger temperature slope and inversely associated with sympathetically mediated HRV during stress-primed alcohol cue-exposure, independent of alcohol dependence severity, time in treatment, alcohol craving, and perceived stress. Study findings suggest that alcohol AB is linked with physiological cue-reactivity and that different attentional strategies are associated with distinct profiles of autonomic responses that may ultimately index or confer additional risk for alcohol dependence.

Alcohol and nicotine dependence are associated with considerable morbidity and mortality, especially when cases are persistent. The risk for alcohol and nicotine dependence is increased by childhood maltreatment. However, the influence of childhood maltreatment on dependence course is unknown, and is evaluated in the current study. Physical, sexual and emotional abuse, and physical and emotional neglect, were evaluated as predictors of persistent alcohol and nicotine dependence over 3 years of follow-up, with and without control for other childhood adversities. National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). NESARC participants completing baseline and follow-up who met criteria at baseline for past-year alcohol dependence (n = 1172) and nicotine dependence (n = 4017). Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS) measures of alcohol/nicotine dependence, childhood maltreatment and other adverse childhood experiences (e.g. parental divorce). Controlling for demographics only, physical, sexual and emotional abuse and physical neglect predicted 3-year persistence of alcohol dependence [adjusted odds ratio (AOR) = 1.50-2.99; 95% CI = 1.04-4.68] and nicotine dependence (AOR = 1.37-1.74; 95% CI = 1.13-2.11). With other childhood adversities also controlled, maltreatment types remained predictive for alcohol persistence (AOR = 1.53-3.02; 95% CI = 1.07-4.71) and nicotine persistence (AOR = 1.35-1.72; 95% CI = 1.11-2.09). Further, a greater number of maltreatment types incrementally influenced persistence risk (AOR = 1.19-1.36; 95% CI = 1.11-1.56). A history of childhood maltreatment predicts persistent adult alcohol and nicotine dependence. This association, robust to control for other childhood adversities, suggests that maltreatment (rather than a generally difficult childhood) affects the course of dependence. © 2014 Society for the Study of Addiction.

The association between two functional polymorphisms in alcohol dehydrogenase (ADH2/ADH1B) and aldehyde dehydrogenase (ALDH2) genes and alcohol dependence was examined in 182 Chinese and Indian patients undergoing treatment for alcohol dependence and 184 screened control subjects from Singapore. All subjects were screened by the Alcohol Use Disorders Identification Test (AUDIT). Patients were also administered the Severity of Alcohol Dependence Questionnaire (SADQ). Polymorphisms were genotyped by allele-specific polymerase chain reaction and selected genotypes confirmed by DNA sequencing or restriction fragment length polymorphism. Our results showed that frequencies of ADH1B*2 and ALDH2*2 were higher in controls compared to alcohol-dependent subjects for both Chinese and Indians. Frequencies of these two alleles were also higher in the 104 Chinese controls compared to the 80 Indian controls. None of the eight Chinese who were homozygous for both protective alleles was alcohol dependent. The higher frequencies of the protective alleles could explain the lower rate of alcohol dependence in Chinese.
Stimulus augmenting and field dependence in children of alcoholic fathers.
Hennecke, L
1984-11-01
The relationship between paternal alcoholism and two perceptual characteristics, stimulus augmenting and field dependence, was tested in boys and girls aged 10-12. Thirty children of alcoholic fathers, presumed at high risk for the disease because of its familial-genetic component, were compared with 30 children of nonalcoholic parents. Stimulus augmenting was measured by the Kinesthetic Figural After-Effect (KFA) test and field dependence by the Embedded Figures Test (EFT). It was reasoned that the consistent findings of field dependence in alcoholics could be a manifestation of brain damage and the consequent cognitive deficits often found in alcoholics. Thus it was proposed that field dependence would not differentiate the children of alcoholic fathers from those of nonalcoholics. No difference in field dependence was found between the groups, which supports other evidence that alcoholism can lead to field dependence. Since KFA scores revealed a significantly higher incidence of stimulus augmenters in the children of alcoholic fathers, it is proposed that stimulus augmenting is premorbid to alcoholism. It remains unclear, however, whether this phenomenon is due to an environmental or genetic factor.

A comprehensive review of cost drivers associated with alcohol abuse, heavy drinking, and alcohol dependence for high-income countries was conducted. The data from 14 identified cost studies were tabulated according to the potential direct and indirect cost drivers. The costs associated with alcohol abuse, alcohol dependence, and heavy drinking were calculated. The weighted average of the total societal cost due to alcohol abuse as percent gross domestic product (GDP)--purchasing power parity (PPP)--was 1.58%. The cost due to heavy drinking and/or alcohol dependence as percent GDP (PPP) was estimated to be 0.96%. On average, the alcohol-attributable indirect cost due to loss of productivity is more than the alcohol-attributable direct cost. Most of the countries seem to incur 1% or more of their GDP (PPP) as alcohol-attributable costs, which is a high toll for a single factor and an enormous burden on public health. The majority of alcohol-attributable costs incurred as a consequence of heavy drinking and/or alcohol dependence. Effective prevention and treatment measures should be implemented to reduce these costs.

Smoking tobacco, drinking alcohol, and chewing betel quid are health-risk behaviors for several diseases, such as cancer, cardiovascular disease, and diabetes, with severe impacts on health. However, health care providers often have limited time to assess clients' behaviors regarding smoking tobacco, drinking alcohol, and chewing betel quid and intervene, if needed. The objective of this study was to develop a Web-based survey system; determine the rates of tobacco-smoking, alcohol-drinking, and betel-quid-chewing behaviors; and estimate the efficiency of the system (time to complete the survey). Patients and their family members or friends were recruited from gastrointestinal medical-surgical, otolaryngology, orthopedics, and rehabilitation clinics or wards at a medical center in northern Taiwan. Data for this descriptive, cross-sectional study were extracted from a large series of research studies. A Web-based survey system was developed using a Linux, Apache, MySQL, PHP stack solution. The Web survey was set up to include four questionnaires: the Chinese-version Fagerstrom Tolerance Questionnaire, the Chinese-version Alcohol Use Disorders Identification Test, the Betel Nut Dependency Scale, and a sociodemographic form with several chronic diseases. After the participants completed the survey, the system automatically calculated their score, categorized their risk level for each behavior, and immediately presented and explained their results. The system also recorded the time each participant took to complete the survey. Of 782 patient participants, 29.6% were addicted to nicotine, 13.3% were hazardous, harmful, or dependent alcohol drinkers, and 1.5% were dependent on chewing betel quid. Of 425 family or friend participants, 19.8% were addicted to nicotine, 5.6% were hazardous, harmful, or dependent alcohol drinkers, and 0.9% were dependent on chewing betel quid. Regarding the mean time to complete the survey, patients took 7.9 minutes (SD 3.0; range 3-20) and family members or friends took 7.7 minutes (SD 2.8; range 3-18). Most of the participants completed the survey within 5-10 minutes. The Web-based survey was easy to self-administer. Health care providers can use this Web-based survey system to save time in assessing these risk behaviors in clinical settings. All smokers had mild-to-severe nicotine addiction, and 5.6%-12.3% of patients and their family members or friends were at risk of alcohol dependence. Considering that these three behaviors, particularly in combination, dramatically increase the risk of esophageal cancer, appropriate and convenient interventions are necessary for preserving public health in Taiwan. ©Kuo-Yao Hsu, Yun-Fang Tsai, Chu-Ching Huang, Wen-Ling Yeh, Kai-Ping Chang, Chen-Chun Lin, Ching-Yen Chen, Hsiu-Lan Lee.

Polymorphisms in the genes encoding alcohol metabolizing enzymes are associated with alcohol dependence. To evaluate the association between the alcohol dehydrogenase 1C (ADH1C) Ile350Val and aldehyde dehydrogenase 2 (ALDH2) Glu504Lys polymorphisms and alcohol dependence in a Turkish sample. 235 individuals (115 alcohol-dependent patients and 120 controls) were genotyped for ADH1C and ALDH2 with PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism). Association between the polymorphisms and family history, daily and maximum amount of alcohol consumed was investigated. The associations between alcohol dependence, severity of consumption and family history and the polymorphisms were analyzed by chi-square or Fisher's exact test where necessary. Relationship between genotypes and dependence related features was evaluated using analysis of variance (ANOVA). The -350Val allele for ADH1C (ADH1C*2) was increased in alcohol-dependent patients (P = 0.05). In individuals with a positive family history, the genotype distribution differed significantly (P = 0.031) and more patients carried the Val allele compared with controls (P = 0.025). Genotyping of 162 participants did not reveal the -504Lys allele in ALDH2. These findings suggest that ADH1C*2 is associated with alcohol dependence in the Turkish population displaying a dominant inheritance model. ADH1C*2 allele may contribute to the variance in heritability of alcohol dependence. The ALDH2 -504Lys/Lys or Glu/Lys genotypes were not present in alcohol-dependent patients, similar to that seen in European populations and in contrast to the findings in the Asian populations.

The study of personality is critical to enhance current knowledge of the psychological characteristics of alcohol dependence. Recent evidence shows that mindfulness-oriented meditation positively influences healthy individuals' character. Here, it was assessed whether 8-week mindfulness-oriented meditation promotes similar changes in a group of alcohol-dependent individuals. A control group with alcohol dependence was also tested. Mindfulness-oriented meditation participants showed an increase in the character scores of the temperament and character inventory together with reduced risks of relapse. These longitudinal data highlight the importance of assessing personality in alcohol-dependent individuals and support the utility of therapeutic interventions for alcohol dependence aimed at enhancing individuals' character.

The aim of this study was to evaluate the importance of alcohol-dependent patients' emotional expressivity, alcohol-related expectations and socio-demographic factors for prediction of motivation to refuse alcohol consumption. The study sample consisted of 136 alcohol-dependent patients (100 men and 36 women) undergoing treatment in Kaunas center for addictive disorders. Only higher expression of negative alcohol-related expectations (std. beta=0.192, P=0.023), higher emotional impulse intensity (std. beta=0.229, P=0.021) and higher expression of positive emotional expressiveness (std. beta=0.021, P=0.020) as well as gender (std. beta=0.180, P=0.049), education (std. beta=-0.137, P=0.038) and alcohol dependency treatment conditions (members of support group after rehabilitation program) (std. beta=0.288, P=0.001; std. beta=0.608, P=0.001) were significant factors for predicting the different level of alcohol-dependent patients motivation to refuse alcohol consumption. Negative alcohol-related expectations, emotional impulse intensity and positive emotional expressiveness were significant even though quite weak triggers for alcohol-dependent patients' different level of motivation to refuse alcohol consumption. An assumption could be made that by changing these triggers it is possible to change addictive behavior. Copyright © 2014 Lithuanian University of Health Sciences.

This study examines comorbidity of alcohol abuse and alcohol dependence as well as its risk indicators among anxious and/or depressed persons, also considering temporal sequencing of disorders. Baseline data from the Netherlands Study of Depression and Anxiety (NESDA) were used, including 2329 persons with lifetime DSM-IV anxiety (social phobia, generalized anxiety disorder, panic disorder, and agoraphobia) and/or depressive (major depressive disorder and dysthymia) disorders and 652 controls. Lifetime diagnoses of DSM-IV alcohol abuse and dependence were established, as well as information about socio-demographic, vulnerability, addiction-related and anxiety/depression-related characteristics. Temporal sequencing of disorders was established retrospectively, using age of onset. Of persons with combined anxiety/depression 20.3% showed alcohol dependence versus 5.5% of controls. Prevalence of alcohol abuse was similar across groups (± 12%). Independent risk indicators for alcohol dependence among anxious and/or depressed persons were male gender, vulnerability factors (family history of alcohol dependence, family history of anxiety/depression, openness to experience, low conscientiousness, being single, and childhood trauma), addiction-related factors (smoking and illicit drug use) and early anxiety/depression onset. Persons with secondary alcohol dependence were more neurotic, more often single and lonelier, while persons with primary alcohol dependence were more often male and more extravert. Alcohol dependence, but not abuse, is more prevalent in anxious and/or depressed persons. Persons with comorbid alcohol dependence constitute a distinct subgroup of anxious and/or depressed persons, characterized by addiction-related habits and vulnerability. However, considerable variation in characteristics exists depending on temporal sequencing of disorders. This knowledge may improve identification and treatment of those anxious and/or depressed patients who are additionally suffering from alcohol dependence. Copyright © 2010 Elsevier B.V.

Background The role of cognitive appraisal of the threat of alcohol relapse has received little attention. A previous instrument, the Relapse Situation Appraisal Questionnaire (RSAQ), was developed to assess cocaine users’ primary appraisal of the threat of situations posing a high risk for cocaine relapse. The purpose of the present study was to modify the RSAQ in order to measure primary appraisal in situations involving a high risk for alcohol relapse. Methods The development and psychometric properties of this instrument, the Alcohol Relapse Situation Appraisal Questionnaire (A-RSAQ), were examined with two samples of abstinent adults with alcohol abuse or dependence. Factor structure and validity were examined in Study 1 (N=104). Confirmation of the factor structure and predictive validity were assessed in Study 2 (N=161). Results Results demonstrated construct, discriminant and predictive validity and reliability of the A-RSAQ. Discussion Results support the important role of primary appraisal of degree of risk in alcohol relapse situations. PMID:21237586

This study investigated the patterns of alcohol disorder comorbidity with other psychiatric disorders, using Korean nationwide epidemiological data. By two-stage cluster sampling, 5,176 adult household residents of Korea were interviewed using the Korean version of the Diagnostic Interview Schedule. Psychiatric disorders strongly associated with alcohol disorders were, other drug abuse or dependence, major depression, simple phobia, antisocial personality disorder, tobacco dependence, and pathological gambling. Male alcoholics had a tendency to begin with tobacco dependence, and some male pathological gamblers first had alcohol disorders. The presence of comorbid psychiatric disorders was associated with a more severe form and the later onset of alcohol disorders, and associated with help-seeking for alcohol abuse/dependence.

Identifying novel treatments that facilitate extinction learning could enhance cue-exposure therapy and reduce high relapse rates in alcoholics. Activation of mGlu5 receptors in the infralimbic prefrontal cortex (IL-PFC) facilitates learning during extinction of cue-conditioned alcohol-seeking behavior. Small-conductance calcium-activated potassium (KCa2) channels have also been implicated in extinction learning of fear memories, and mGlu5 receptor activation can reduce KCa2 channel function. Using a combination of electrophysiological, pharmacological, and behavioral approaches, this study examined KCa2 channels as a novel target to facilitate extinction of alcohol-seeking behavior in rats. This study also explored related neuronal and synaptic mechanisms within the IL-PFC that underlie mGlu5-dependent enhancement of extinction learning. Using whole-cell patch-clamp electrophysiology, activation of mGlu5 in ex vivo slices significantly reduced KCa2 channel currents in layer V IL-PFC pyramidal neurons, confirming functional downregulation of KCa2 channel activity by mGlu5 receptors. Additionally, positive modulation of KCa2 channels prevented mGlu5 receptor-dependent facilitation of long-term potentiation in the IL-PFC. Systemic and intra-IL-PFC treatment with apamin (KCa2 channel allosteric inhibitor) significantly enhanced extinction of alcohol-seeking behavior across multiple extinction sessions, an effect that persisted for 3 weeks, but was not observed after apamin microinfusions into the prelimbic PFC. Positive modulation of IL-PFC KCa2 channels significantly attenuated mGlu5-dependent facilitation of alcohol cue-conditioned extinction learning. These data suggest that mGlu5-dependent facilitation of extinction learning and synaptic plasticity in the IL-PFC involves functional inhibition of KCa2 channels. Moreover, these findings demonstrate that KCa2 channels are a novel target to facilitate long-lasting extinction of alcohol-seeking behavior. SIGNIFICANCE STATEMENT Alcohol use disorder is a chronic relapsing disorder that is associated with compulsive alcohol-seeking behavior. One of the main causes of alcohol relapse is the craving caused by environmental cues that are associated with alcohol. These cues are formed by normal learning and memory principles, and the understanding of the brain mechanisms that help form these associations can lead to the development of drugs and/or behavior therapies that reduce the impact that these cues have on relapse in alcoholics.

Introduction Prenatal alcohol exposure via maternal liquid diet consumption by C57BL/6 (B6) mice causes conspicuous midline neural tube deficit (dysraphia) and disruption of genesis and development of serotonin (5-HT) neurons in the raphe nuclei, together with brain growth retardation. The current study tested the hypothesis that concurrent treatment with either an activity-dependent neurotrophic factor (ADNF) agonist peptide [SALLRSIPA, (SAL)] or an activity-dependent neurotrophic protein (ADNP) agonist peptide [NAPVSIPQ, (NAP)] would protect against these alcohol-induced deficits in brain development. Methods Timed-pregnant B6 dams consumed alcohol from embryonic day 7 (E7, before the onset of neurulation) until E15. Fetuses were obtained on E15 and brain sections processed for 5-HT immunocytochemistry, for evaluation of morphologic development of the brainstem raphe and its 5-HT neurons. Additional groups were treated either with SAL or NAP daily from E7 to E15 to assess the potential protective effects of these peptides. Measures of incomplete occlusion of the ventral canal and the frequency and extent of the openings in the rhombencephalon were obtained to assess fetal dysraphia. Counts of 5-HT-immunostained neurons were also obtained in the rostral and caudal raphe. Results Prenatal alcohol exposure resulted in abnormal openings along the midline and delayed closure of ventral canal in the brainstem. This dysraphia was associated with reductions in the number of 5-HT neurons both in the rostral raphe nuclei (that gives rise to ascending 5-HT projections) and in the caudal raphe (that gives rise to the descending 5-HT projections). Concurrent treatment of the alcohol-consuming dams with SAL prevented dysraphia and protected against the alcohol-induced reductions in 5-HT neurons in both the rostral and caudal raphe. NAP was less effective in protecting against dysraphia and did not protect against 5-HT loss in the rostral raphe, but did protect against loss in the caudal raphe. Conclusions These findings further support the potential usefulness of these peptides for therapeutic interventions in pregnancies at risk for alcohol-induced developmental deficits. Notably, the ascending 5-HT projections of the rostral raphe have profound effects in regulating forebrain development and function, and the descending 5-HT projections of the caudal raphe are critical for regulating respiration. Protection of the rostral 5-HT-system may help prevent structural and functional deficits linked to abnormal forebrain development, and protection of the caudal systems may also reduce the increased risk for sudden infant death syndrome associated with prenatal alcohol exposure.

Posttraumatic Stress Disorder (PTSD) changes the way people think about themselves, others, and the safety of the world. These cognitions may play a role in alcohol dependence, where alcohol dependence is maintained as an attempt to manage posttraumatic anxiety. The current study examined black-white differences in various PTSD cognitions and their relationship to symptoms of alcohol dependence in a dually diagnosed sample (N=167). Analyses revealed racial differences in trauma cognitions and their impact on symptoms of alcohol dependence, suggesting that trauma cognitions are more strongly associated with adverse consequences of drinking and alcohol craving severity among African Americans than European Americans. Additional relationships between ethnic identification and trauma-related cognitions are described and theoretical and clinical implications of these findings are discussed. PMID:21930346
Physical dependence on nitrous oxide in mice: resemblance to alcohol but not to opiate withdrawal.
Milne, B; Cervenko, F W; Jhamandas, K H
1981-01-01
Mice of two strains, Crl:CD-1(1CR)Br and C57BL6, were exposed to nitrous oxide at concentrations of 50, 65 and 80 per cent for 34 or 68 hours. Cessation of nitrous oxide resulted in characteristic convulsions similar to those seen in alcohol withdrawal in all mice. These peaked in severity within 2-3 minutes after removal from nitrous oxide and declined over 6 hours. The severity and duration of these convulsions were related to the nitrous oxide concentration and duration of exposure. Naloxone or naltrexone produced no significant increase in severity of convulsions. The narcotic antagonists did not precipitate acute weight loss or characteristic jumping behaviour seen in animals dependent on opiates. These results demonstrate that chronic exposure to nitrous oxide results in development of physical dependence which resembles alcohol and not opiate dependence. Analgesia and physical dependence produced by nitrous oxide appear to be mediated through separate mechanisms.
Postdependent state in rats as a model for medication development in alcoholism.
Meinhardt, Marcus W; Sommer, Wolfgang H
2015-01-01
Rational development of novel therapeutic strategies for alcoholism requires understanding of its underlying neurobiology and pathophysiology. Obtaining this knowledge largely relies on animal studies. Thus, choosing the appropriate animal model is one of the most critical steps in pre-clinical medication development. Among the range of animal models that have been used to investigate excessive alcohol consumption in rodents, the postdependent model stands out. It was specifically developed to test the role of negative affect as a key driving force in a perpetuating addiction cycle for alcoholism. Here, we will describe our approach to make rats dependent via chronic intermittent exposure to alcohol, discuss the validity of this model, and compare it with other commonly used animal models of alcoholism. We will summarize evidence that postdependent rats fulfill several criteria of a 'Diagnostic and Statistical Manual of Mental Disorders IV/V-like' diagnostic system. Importantly, these animals show long-lasting excessive consumption of and increased motivation for alcohol, and evidence for loss of control over alcohol intake. Our conclusion that postdependent rats are an excellent model for medication development for alcoholism is underscored by a summary of more than two dozen pharmacological tests aimed at reversing these abnormal alcohol responses. We will end with open questions on the use of this model. In the tradition of the Sanchis-Segura and Spanagel review, we provide comic strips that illustrate the postdependent procedure and relevant phenotypes in this review. © 2014 Society for the Study of Addiction.

To understand the molecular and neural mechanisms underlying alcohol addiction, many models ranging from vertebrates to invertebrates have been developed. In Drosophila melanogaster, behavioral paradigms from assaying acute responses to alcohol, to behaviors more closely modeling addiction, have emerged in recent years. However, both the CAFÉ assay, similar to a 2-bottle choice consumption assay, as well as conditioned odor preference, where ethanol is used as the reinforcer, are labor intensive and have low throughput. To address this limitation, we have established a novel ethanol consumption preference assay, called FRAPPÉ, which allows for fast, high throughput measurement of consumption in individual flies, using a fluorescence plate reader. We show that naïve flies do not prefer to consume ethanol, but various pre-exposures, such as ethanol vapor or voluntary ethanol consumption, induce ethanol preference. This ethanol-primed preference is long lasting and is not driven by calories contained in ethanol during the consumption choice. Our novel experience-dependent model of ethanol preference in Drosophila – a highly genetically tractable organism – therefore recapitulates salient features of human alcohol abuse and will facilitate the molecular understanding of the development of alcohol preference.

This study was conducted to assess the association of "diagnostic orphans" at baseline and subsequent development of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol use disorders (AUDs) 5 years later. A sample of 8,534 respondents was drawn from the National Longitudinal Survey of Youth for the years 1989 and 1994. Diagnostic orphans were defined as respondents who met one or two alcohol dependence symptom criteria but did not meet the criteria for a diagnosis of alcohol abuse or dependence. Using multinomial logistic regression analysis, 1994 assessments of DSM-IV AUD were regressed on 1989 baseline assessments of diagnostic orphan status and DSM-IV AUD. In addition to demographic characteristics, other background variables included heavy episodic drinking at baseline and early problem behaviors (antisocial behaviors, illicit substance use, and age at onset of alcohol use). Findings from this 5-year prospective study indicate that diagnostic orphan status at baseline was predictive of DSM-IV AUD at follow-up. These associations remained significant when other early behavioral problems were included in the models. The present findings have important diagnostic implications for the proposed DSM-V, particularly for a dimensional diagnosis incorporating less severe forms of alcohol dependence.

To understand current awareness of, and views on, treatment of alcohol dependence in Japan. (a) Nationwide internet-based survey of 520 individuals, consisting of 52 diagnosed alcohol-dependent (AD) persons, 154 potentially alcohol-dependent (ADP) persons, 104 family members and 106 friends/colleagues of AD persons, and 104 general individuals, derived from a consumer panel where the response rate was 64.3%. We enquired into awareness about the treatment of alcohol dependence and patient pathways through the healthcare network. (b) Nationwide internet-based survey of physicians (response rate 10.1% (2395/23,695) to ask 200 physicians about their management of alcohol use disorders). We deduced that 10% of alcohol-dependent Japanese persons had ever been diagnosed with alcohol dependence, with only 3% ever treated. Regarding putative treatment goals, 20-25% of the AD and ADP persons would prefer to attempt to abstain, while 60-75% preferred 'reduced drinking.' A half of the responding physicians considered abstinence as the primary treatment goal in alcohol dependence, while 76% considered reduced drinking as an acceptable goal. AD and ADP persons in Japan have low 'disease awareness' defined as 'understanding of signs, symptoms and consequences of alcohol use disorders,' which is in line with the overseas situation. The Japanese drinking culture and stigma toward alcohol dependence may contribute to such low disease awareness and current challenging treatment environment. While abstinence remains the preferred treatment goal among physicians, reduced drinking seems to be an acceptable alternative treatment goal to many persons and physicians in Japan. © The Author 2014.

To examine among alcohol-dependent out-patient clients the concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) total score and 'zones' suggested by the World Health Organization for defining levels of severity of alcohol use problems. Participants were classified into AUDIT zones (AUDIT total score = 8-15, 16-19, 20-40) and compared on measures of demographics, treatment goals, alcohol consumption, alcohol-related consequences, severity of dependence, physiological dependence, tolerance, withdrawal and biomarkers of alcohol use. Eleven out-patient academic clinical research centers across the United States. Participants Alcohol dependent individuals (n = 1335) entering out-patient treatment in the Combined Pharmacotherapies and Behavioral Interventions (COMBINE) study. The AUDIT was administered as part of an initial screening. Baseline measures used for concurrent validation included the Structured Clinical Interview for Diagnostic and Statistical Manual, 4th edition (DSM-IV) Disorders, the Alcohol Dependence Scale, the Drinker Inventory of Consequences, the Obsessive-Compulsive Drinking Scale, the University of Rhode Island Change Assessment, the Thoughts about Abstinence Scale, the Form-90, %carbohydrate-deficient transferrin and gamma-glutamyl transferase. Findings Indicators of severity of dependence and alcohol-related problems increased linearly with total score and differed significantly across AUDIT zones. The highest zone, with scores of 20 and above, was markedly different with respect to severity from the other two zones and members of this group endorsed an abstinence goal more strongly. The AUDIT total score is a brief measure that appears to provide an index of severity of dependence in a sample of alcohol-dependent individuals seeking out-patient treatment, extending its potential utility beyond its more traditional role as a screening instrument in general populations.

Alcohol dependence causes physical, social, and moral harms and currently represents an important public health concern. According to the World Health Organization (WHO), alcoholism is the third leading cause of death worldwide, after tobacco consumption and hypertension. Recent epidemiologic studies have shown a growing trend in alcohol abuse among adolescents, characterized by the consumption of large doses of alcohol over a short time period. Since brain development is an ongoing process during adolescence, short- and long-term brain damage associated with drinking behavior could lead to serious consequences for health and wellbeing. Accumulating evidence indicates that alcohol impairs the function of different components of the melanocortin system, a major player involved in the consolidation of addictive behaviors during adolescence and adulthood. Here, we hypothesize the possible implications of melanocortins and glial cells in the onset and progression of alcohol addiction. In particular, we propose that alcohol-induced decrease in α-MSH levels may trigger a cascade of glial inflammatory pathways that culminate in altered gliotransmission in the ventral tegmental area and nucleus accumbens (NAc). The latter might potentiate dopaminergic drive in the NAc, contributing to increase the vulnerability to alcohol dependence and addiction in the adolescence and adulthood. PMID:28424592

Alcohol dependence is more prevalent in men than in women. The evidence for how prenatal and adult androgens influence alcohol dependence is limited. We investigated the effects of prenatal and adult androgen activity on alcohol dependence. Moreover, we studied how the behaviours of pregnant women affect their children's prenatal androgen load. We quantified prenatal androgen markers (e.g., second-to-fourth finger length ratio [2D : 4D]) and blood androgens in 200 early-abstinent alcohol-dependent in-patients and 240 controls (2013-2015, including a 12-month follow-up). We also surveyed 134 women during pregnancy (2005-2007) and measured the 2D : 4D of their children (2013-2016). The prenatal androgen loads were higher in the male alcohol-dependent patients compared to the controls (lower 2D : 4D, P = 0.004) and correlated positively with the patients' liver transaminase activities (P < 0.001) and alcohol withdrawal severity (P = 0.019). Higher prenatal androgen loads and increasing androgen levels during withdrawal predicted earlier and more frequent 12-month hospital readmission in alcohol-dependent patients (P < 0.005). Moreover, stress levels (P = 0.002), alcohol (P = 0.010) and tobacco consumption (P = 0.017), and lifetime stressors (P = 0.019) of women during pregnancy related positively to their children's prenatal androgen loads (lower 2D : 4D). Androgen activities in alcohol-dependent patients and behaviours of pregnant women represent novel preventive and therapeutic targets of alcohol dependence. © 2017 John Wiley & Sons A/S.

The increased susceptibility for developing alcohol dependence seen in offspring from families with alcohol dependence may be related to structural and functional differences in brain circuits that influence emotional processing. Early childhood environment, genetic variation in the serotonin transporter-linked polymorphic region (5-HTTLPR) of the SLCA4 gene and allelic variation in the Brain Derived Neurotrophic Factor (BDNF) gene have each been reported to be related to volumetric differences in the temporal lobe especially the amygdala. Magnetic resonance imaging was used to obtain amygdala volumes for 129 adolescent/young adult individuals who were either High-Risk (HR) offspring from families with multiple cases of alcohol dependence (N=71) or Low-Risk (LR) controls (N=58). Childhood family environment was measured prospectively using age-appropriate versions of the Family Environment Scale during a longitudinal follow-up study. The subjects were genotyped for Brain-Derived Neurotrophic Factor (BDNF) Val66Met and the serotonin transporter polymorphism (5-HTTLPR). Two family environment scale scores (Cohesion and Conflict), genotypic variation, and their interaction were tested for their association with amygdala volumes. Personal and prenatal exposure to alcohol and drugs were considered in statistical analyses in order to more accurately determine the effects of familial risk group differences. Amygdala volume was reduced in offspring from families with multiple alcohol dependent members in comparison to offspring from control families. High-Risk offspring who were carriers of the S variant of the 5-HTTLPR polymorphism had reduced amygdala volume in comparison to those with an LL genotype. Larger amygdala volume was associated with greater family cohesion but only in Low-Risk control offspring. Familial risk for alcohol dependence is an important predictor of amygdala volume even when removing cases with significant personal exposure and covarying for prenatal exposure effects. The present study provides new evidence that amygdala volume is modified by 5-HTTLPR variation in High-Risk families.
Contribution of Dynorphin and Orexin Neuropeptide Systems to the Motivational Effects of Alcohol.
Anderson, Rachel I; Moorman, David E; Becker, Howard C
2018-03-11
Understanding the neural systems that drive alcohol motivation and are disrupted in alcohol use disorders is of critical importance in developing novel treatments. The dynorphin and orexin/hypocretin neuropeptide systems are particularly relevant with respect to alcohol use and misuse. Both systems are strongly associated with alcohol-seeking behaviors, particularly in cases of high levels of alcohol use as seen in dependence. Furthermore, both systems also play a role in stress and anxiety, indicating that disruption of these systems may underlie long-term homeostatic dysregulation seen in alcohol use disorders. These systems are also closely interrelated with one another - dynorphin/kappa opioid receptors and orexin/hypocretin receptors are found in similar regions and hypocretin/orexin neurons also express dynorphin - suggesting that these two systems may work together in the regulation of alcohol seeking and may be mutually disrupted in alcohol use disorders. This chapter reviews studies demonstrating a role for each of these systems in motivated behavior, with a focus on their roles in regulating alcohol-seeking and self-administration behaviors. Consideration is also given to evidence indicating that these neuropeptide systems may be viable targets for the development of potential treatments for alcohol use disorders.

Little is known about the correlates of comorbid drug and alcohol dependence in people with schizophrenia outside the USA. We tested hypotheses that dependence on alcohol/drugs would be associated with more severe symptoms, and poorer psychosocial functioning and quality of life. The EuroSC Cohort study (N=1204), based in France, Germany and the UK, used semi-structured clinical interviews for diagnoses, and standardized tools to assess correlates. We used mixed models to compare outcomes between past-year comorbid dependence on alcohol/drugs, controlling for covariates and modelling both subject and country-level effects. Participants dependent on alcohol or drugs had fewer negative symptoms on PANSS than their non-dependent counterparts. However, those dependent on alcohol scored higher on PANSS general psychopathology than those who were not, or dependent only on drugs. People with schizophrenia dependent on drugs had poorer quality of life, more extrapyramidal side effects, and scored worse on Global Assessment of Functioning (GAF) than those without dependence. People with alcohol dependence reported more reasons for non-compliance with medication, and poorer functioning on GAF, though not on Global Assessment of Relational Functioning. In people with schizophrenia, comorbid dependence on alcohol or drugs is associated with impaired clinical and psychosocial adjustment, and poorer quality of life.

Heritability of MMPI-2 scales in the UCSF Family Alcoholism Study

2009-01-01
The present study evaluated the heritability of personality traits and psychopathology symptoms assessed by the Minnesota Multiphasic Personality Interview 2nd edition (MMPI-2) in a family-based sample selected for alcohol dependence. Participants included 950 probands and 1204 first-degree relatives recruited for the UCSF Family Alcoholism Study. Heritability estimates (h2) for MMPI-2 scales ranged from .25–.49. When alcohol dependence was used as a covariate, heritability estimates remained significant but generally declined. However, when the MMPI-2 scales were used as covariates to estimate the heritability of alcohol dependence, scales measuring antisocial behavior (ASP), depressive symptoms (DEP), and addictive behavior (MAC-R) led to moderate increases in the heritability of alcohol dependence. This suggests that the ASP, DEP, and MAC-R scales may explain some of the non-genetic variance in the alcohol dependence diagnosis in this population when utilized as covariates, and thus may serve to produce a more homogeneous and heritable alcohol dependence phenotype.

Alcohol dependence as a chronic pain disorder
Egli, Mark; Koob, George F.; Edwards, Scott
2013-01-01
Dysregulation of pain neurocircuitry and neurochemistry has been increasingly recognized as playing a critical role in a diverse spectrum of diseases including migraine, fibromyalgia, depression, and PTSD. Evidence presented here supports the hypothesis that alcohol dependence is among the pathologies arising from aberrant neurobiological substrates of pain. In this review, we explore the possible influence of alcohol analgesia and hyperalgesia in promoting alcohol misuse and dependence. We examine evidence that neuroanatomical sites involved in the negative emotional states of alcohol dependence also play an important role in pain transmission and may be functionally altered under chronic pain conditions. We also consider possible genetic links between pain transmission and alcohol dependence. We propose an allostatic load model in which episodes of alcohol intoxication and withdrawal, traumatic stressors, and injury are each capable of dysregulating an overlapping set of neural substrates to engender sensory and affective pain states that are integral to alcohol dependence and comorbid conditions such as anxiety, depression, and chronic pain.

Most studies have demonstrated that alcohol consumption is associated with decreased fertility. The aim of this study was to investigate the effects of alcohol on pre-implantation embryo transport and/or early embryo development in the oviduct. We reported here that ethanol concentration-dependently suppressed the spontaneous motility of isolated human oviduct strips (EC50 50±6mM), which was largely attenuated in the present of L-NAME, a classical nitric oxide synthase(NOS) competitive inhibitor. Notably, either acute or chronic alcohol intake delayed egg transport and retarded early development of the embryo in the mouse oviduct, which was largely rescued by co-administration of L-NAME in a acute alcohol intake group but not in chronic alcohol intake group. It is worth mentioning that the oviductal epithelium destruction was verified by scanning electron microscope (SEM) observations in chronic alcohol intake group. In conclusion, alcohol intake delayed egg transport and retarded early development of the embryo in the oviduct by suppressing the spontaneous motility of oviduct and/or impairing oviductal epithelium. These findings suggested that alcohol abuse increases the incident of ectopic pregnancy. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

High alcohol consumption is associated with an increased risk of severe liver disease. Current recommendations suggest it is safe for men to consume 30 grams of alcohol per day. We investigated the association between alcohol consumption early in life and later development of severe liver disease. We used data on alcohol consumption at conscription to military service from 43,296 men (18-20 years) in Sweden between 1969 and 1970. Outcomes were defined as incident diagnoses of severe liver disease from systematic national registration of clinical events until the end of 2009. A Cox regression model adjusted for body mass index, smoking, use of narcotics, cognitive ability and cardiovascular capacity was applied. During a mean follow-up of 37.8 years, 383 men developed severe liver disease. Alcohol consumption was associated with an increased risk of development of severe liver disease in a dose-response pattern (adjusted hazard ratio for every one gram/day increase 1.02; 95% CI 1.01-1.02). No evidence of a threshold effect was found. Importantly, a clear trend pointed towards an increased risk of severe liver disease in men who consumed less than 30 grams of alcohol per day. Alcohol consumption in young men is associated with an increased risk of severe liver disease, up to 39 years later in life. The risk was dose-dependent, with no sign of a threshold effect. Current guidelines for safe alcohol intake in men might have to be revised. We investigated more than 43,000 Swedish men in their late teens enlisted for conscription in 1969-1970. After almost 40 years of follow-up, we found that alcohol consumption was a significant risk factor for developing severe liver disease, independent of confounders. This risk was dose-dependent, and was most pronounced in men consuming two drinks per day or more. Copyright © 2017 European Association for the Study of the Liver. Published by Elsevier B.V.

This study assessed personality disorders (PDs) in 158 alcohol-dependent outpatients (62 manifesting cocaine abuse and 96 without cocaine abuse) with the International Personality Disorders Examination interview between 2003 and 2006. Thirty-nine alcohol-dependent/cocaine abusers (62.9% of this group) and 51 only alcohol-dependent patients (53.1% of this group) manifested at least one PD. There were no statistically significant differences between groups in the overall prevalence rate of PDs. The most prevalent PDs, among the alcohol-dependent/cocaine abusers, were antisocial (21%), narcissistic (14.5%), and borderline (11.3%) PDs. The most frequently diagnosed PDs among the only alcohol-dependent patients were obsessive-compulsive (20.8%), paranoid (10.4%), and dependent (9.4%) PDs. There were significant differences between the groups. The study limitations are discussed.

Alcohol dependence is among the most severely stigmatized mental disorders. We examine whether negative stereotypes and illness beliefs related to alcohol dependence have changed between 1990 and 2011. We used data from two population surveys with identical methodology that were conducted among German citizens aged ≥18 years, living in the 'old' German states. They were conducted in 1990 and 2011, respectively. In random subsamples (1990: n = 1,022, and 2011: n = 1,167), identical questions elicited agreement with statements regarding alcohol dependence, particularly with regard to the illness definition of alcohol dependence and blame. Overall, agreement with negative stereotypes did not change in the course of 2 decades. About 55% of the respondents agreed that alcohol dependence is an illness like any other, >40% stated that it was a weakness of character and 30% endorsed that those affected are themselves to blame for their problems. It is apparent that promoting an illness concept of alcohol dependence has not been an easy solution to the problem of stigma. We discuss how the normative functions of alcohol dependence stigma might have prevented a reduction of negative stereotypes. © 2014 S. Karger AG, Basel.

There is a considerable body of literature demonstrating that adolescence is a unique age period, which includes rapid and dramatic maturation of behavioral, cognitive, hormonal and neurobiological systems. Most notably, adolescence is also a period of unique responsiveness to alcohol effects, with both hyposensitivity and hypersensitivity observed to the various effects of alcohol. Multiple neurotransmitter systems are undergoing fine-tuning during this critical period of brain development, including those that contribute to the rewarding effects of drugs of abuse. The role of developmental maturation of the γ-amino-butyric acid (GABA) system, however, has received less attention in contributing to age-specific alcohol sensitivities. This review integrates GABA findings from human magnetic resonance spectroscopy studies as they may translate to understanding adolescent-specific responsiveness to alcohol effects. Better understanding of the vulnerability of the GABA system both during adolescent development, and in psychiatric conditions that include alcohol dependence, could point to a putative mechanism, boosting brain GABA, that may have increased effectiveness for treating alcohol abuse disorders.

Chronic alcohol consumption causes a spectrum of liver diseases, but the pathogenic mechanisms driving the onset and progression of disease are not clearly defined. We show that chronic alcohol feeding sensitizes rat hepatocytes to Ca 2+ -mobilizing hormones resulting in a leftward shift in the concentration-response relationship and the transition from oscillatory to more sustained and prolonged Ca 2+ increases. Our data demonstrate that alcohol-dependent adaptation in the Ca 2+ signalling pathway occurs at the level of hormone-induced inositol 1,4,5 trisphosphate (IP 3 ) production and does not involve changes in the sensitivity of the IP 3 receptor or size of internal Ca 2+ stores. We suggest that prolonged and aberrant hormone-evoked Ca 2+ increases may stimulate the production of mitochondrial reactive oxygen species and contribute to alcohol-induced hepatocyte injury. ABSTRACT: 'Adaptive' responses of the liver to chronic alcohol consumption may underlie the development of cell and tissue injury. Alcohol administration can perturb multiple signalling pathways including phosphoinositide-dependent cytosolic calcium ([Ca 2+ ] i ) increases, which can adversely affect mitochondrial Ca 2+ levels, reactive oxygen species production and energy metabolism. Our data indicate that chronic alcohol feeding induces a leftward shift in the dose-response for Ca 2+ -mobilizing hormones resulting in more sustained and prolonged [Ca 2+ ] i increases in both cultured hepatocytes and hepatocytes within the intact perfused liver. Ca 2+ increases were initiated at lower hormone concentrations, and intercellular calcium wave propagation rates were faster in alcoholics compared to controls. Acute alcohol treatment (25 mm) completely inhibited hormone-induced calcium increases in control livers, but not after chronic alcohol-feeding, suggesting desensitization to the inhibitory actions of ethanol. Hormone-induced inositol 1,4,5 trisphosphate (IP 3 ) accumulation and phospholipase C (PLC) activity were significantly potentiated in hepatocytes from alcohol-fed rats compared to controls. Removal of extracellular calcium, or chelation of intracellular calcium did not normalize the differences in hormone-stimulated PLC activity, indicating calcium-dependent PLCs are not upregulated by alcohol. We propose that the liver 'adapts' to chronic alcohol exposure by increasing hormone-dependent IP 3 formation, leading to aberrant calcium increases, which may contribute to hepatocyte injury. © 2017 The Authors.

As programs for screening, brief intervention, and referral to treatment (SBIRT) for unhealthy alcohol use disseminate, evidence-based approaches for identifying patients with unhealthy alcohol use and alcohol dependence (AD) are needed. While the National Institute on Alcohol Abuse and Alcoholism Clinician Guide suggests use of a single alcohol screening question (SASQ) for screening and Diagnostic and Statistical Manual checklists for assessment, many SBIRT programs use alcohol use disorders identification test (AUDIT) "zones" for screening and assessment. Validation data for these zones are limited. This study used primary care data from a bi-ethnic southern U.S. population to examine the ability of the AUDIT zones and other AUDIT-based approaches to identify unhealthy alcohol use and dependence. Existing data were analyzed from interviews with 625 female and male adult drinkers presenting to 5 southeastern primary care practices. Timeline follow-back was used to identify at-risk drinking, and diagnostic interview schedule was used to identify alcohol abuse and dependence. Validity measures compared performance of AUDIT, AUDIT-C, and AUDIT dependence domains scores, with and without a 30-day binge drinking measure, for detecting unhealthy alcohol use and dependence. Optimal AUDIT scores for detecting unhealthy alcohol use were lower than current commonly used cutoffs (5 for men, 3 for women). Improved performance was obtained by combining AUDIT cutoffs of 6 for men and 4 for women with a 30-day binge drinking measure. AUDIT scores of 15 for men and 13 for women detected AD with 100% specificity but low sensitivity (20 and 18%, respectively). AUDIT dependence subscale scores of 2 or more showed similar specificity (99%) and slightly higher sensitivity (31% for men, 24% for women). Combining lower AUDIT cutoff scores and binge drinking measures may increase the detection of unhealthy alcohol use in primary care. Use of lower cutoff scores and dependence subscale scores may increase diagnosis of AD; however, better measures for detecting dependence are needed.

Objective: The current study examines the relation between peer descriptive norms for alcohol involvement and alcohol-dependence symptomatology and whether this relation differs as a function of sexual self-concept ambiguity (SSA). This study also examines the associations among peer descriptive norms for alcohol involvement, alcohol-dependence symptomatology, and lifetime HIV risk-taking behavior and how these relations are influenced by SSA. Method: Women between ages 18 and 30 years (N = 351; M = 20.96, SD = 2.92) completed an online survey assessing sexual self-concept, peer descriptive norms, alcohol-dependence symptomatology, and HIV risk-taking behaviors. Structural equation modeling was used to test hypotheses of interest. Results: There was a significant latent variable interaction between SSA and descriptive norms for peer alcohol use. There was a stronger positive relationship between peer descriptive norms for alcohol and alcohol-dependence symptomatology when SSA was higher compared with when SSA was lower. Both latent variables exhibited positive simple associations with alcohol-dependence symptoms. Peer descriptive norms for alcohol involvement directly and indirectly influenced HIV risk-taking behaviors, and the indirect influence was conditional based on SSA. Conclusions: The current findings illustrate complex, nuanced associations between perceived norms, identity-related self-concepts, and risky health behaviors from various domains. Future intervention efforts may be warranted to address both problem alcohol use and HIV-risk engagement among individuals with greater sexual self-concept ambiguity. PMID:25343661

Background Binge drinking during adolescence is associated with increased risk for developing alcohol use disorders (AUDs); however, the neural mechanisms underlying this liability are unclear. In this study, we sought to determine if binge-drinking alters expression or phosphorylation of two molecular mechanisms of neuroplasticity, calcium/calmodulin dependent kinase II alpha (CaMKIIα) and the GluA1 subunit of AMPA receptors (AMPAR) in addiction-associated brain regions. We also asked if activation of CaMKIIα-dependent AMPAR activity escalates binge-like drinking. Methods To address these questions, CaMKIIαT286 and GluA1S831 protein phosphorylation and expression were assessed in the amygdala and striatum of adolescent and adult male C57BL/6J mice immediately after voluntary binge-like alcohol drinking (blood alcohol > 80mg/dL). In separate mice, effects of the CaMKIIα-dependent pGluA1S831-enhancing drug tianeptine were tested on binge-like alcohol consumption in both age groups. Results Binge-like drinking decreased CaMKIIαT286 phosphorylation (pCaMKIIαT286) selectively in adolescent amygdala with no effect in adults. Alcohol also produced a trend for reduced pGluA1S831 expression in adolescent amygdala but differentially increased pGluA1S831 in adult amygdala. No effects were observed in the nucleus accumbens or dorsal striatum. Tianeptine increased binge-like alcohol consumption in adolescents but decreased alcohol consumption in adults. Sucrose consumption was similarly decreased by tianeptine pretreatment in both ages. Conclusions These data show that the adolescent and adult amygdalae are differentially sensitive to effects of binge-like alcohol drinking on plasticity-linked glutamate signaling molecules. Tianeptine-induced increases in binge-like drinking only in adolescents suggest that differential CaMKIIα-dependent AMPAR activation may underlie age-related escalation of binge drinking.

The authors aimed to explore the relation between nicotine dependence and the severity of aggression among Turkish male alcohol-dependent inpatients who smoked cigarettes, as well as the effect of aggression in these groups. Participants were 126 male alcohol-dependent inpatients who were given the Structured Clinical Interview for DSM-IV, Substance Use Disorder Module (A. Corapcioglu, O. Aydemir, & M. Yildiz, 1999; M. B. First, R. L. Spitzer, & J. B. W. Williams, 1997), the Fagerstrom Test for Nicotine Dependence (K. O. Fagerstrom, 1978), and the Overt Aggression Scale (OAS; S. C. Yudofsky, J. M. Silver, W. Jackson, J. Endicott, & D. Williams, 1986). The authors found differences between male alcohol-dependent inpatients with nicotine dependence (n = 94) and those with nondependence (n = 32) in OAS subtypes. The authors' findings showed that smoking cigarettes-an addiction frequently observed with alcoholism-was positively correlated with aggressive behaviors. The authors suggest that smoking cigarettes may cause aggression or aggression may cause smoking. Observing and evaluating how aggression and smoking cigarettes are associated with alcohol dependence may help relapse prevention and improve effectiveness of treatment interventions in alcoholism.

Aims: To understand current awareness of, and views on, treatment of alcohol dependence in Japan. Methods: (a) Nationwide internet-based survey of 520 individuals, consisting of 52 diagnosed alcohol-dependent (AD) persons, 154 potentially alcohol-dependent (ADP) persons, 104 family members and 106 friends/colleagues of AD persons, and 104 general individuals, derived from a consumer panel where the response rate was 64.3%. We enquired into awareness about the treatment of alcohol dependence and patient pathways through the healthcare network. (b) Nationwide internet-based survey of physicians (response rate 10.1% (2395/23,695) to ask 200 physicians about their management of alcohol use disorders). Results: We deduced that 10% of alcohol-dependent Japanese persons had ever been diagnosed with alcohol dependence, with only 3% ever treated. Regarding putative treatment goals, 20–25% of the AD and ADP persons would prefer to attempt to abstain, while 60–75% preferred ‘reduced drinking.’ A half of the responding physicians considered abstinence as the primary treatment goal in alcohol dependence, while 76% considered reduced drinking as an acceptable goal. Conclusion: AD and ADP persons in Japan have low ‘disease awareness’ defined as ‘understanding of signs, symptoms and consequences of alcohol use disorders,’ which is in line with the overseas situation. The Japanese drinking culture and stigma toward alcohol dependence may contribute to such low disease awareness and current challenging treatment environment. While abstinence remains the preferred treatment goal among physicians, reduced drinking seems to be an acceptable alternative treatment goal to many persons and physicians in Japan. PMID:24893604

The problem of coping with stress is an important one in the context of development and persistence of alcohol dependence. In the literature to date very little attention has been paid to coping patterns construed as a configuration of specific coping styles, particularly as regards the functioning of addicted individuals. The aim of the study was to verify whether individuals with alcohol dependence characterized by different coping patterns differ with respect to the severity of psychopathological symptoms, defense mechanisms and time perspectives. Participants were given a battery of psychological tests-Coping Inventory for Stresfull Situations (CISS), Defense Style Questionnaire (DSQ 40), Syndrom Checklist (SCL-90) and Short Zimbardo Time Perspective Inventory (SZPTI-PL). The sample comprised 112 individuals with alcohol dependence, aged 20 to 63 years old, the average age was 37.86; 78 percent were men. There were identified three sub-groups of individuals characterized by a distinctive patterns of coping with stress -"emotional-avoidant", "task oriented" and a "mixed one". Individuals with the predominant emotional-avoidant coping pattern are characterized by significantly higher severity of psychopathological symptoms, less mature defense mechanisms and past time perspectives. Subjects reliant on task-oriented coping pattern were characterized by the highest level of adaptation and the most constructive way of functioning in the face of difficulties. It is worth regarding the examination of patterns of coping as an indispensable element of collecting medical history from alcohol dependent individuals.

Objectives To determine whether nalmefene combined with psychosocial support is cost-effective compared with psychosocial support alone for reducing alcohol consumption in alcohol-dependent patients with high/very high drinking risk levels (DRLs) as defined by the WHO, and to evaluate the public health benefit of reducing harmful alcohol-attributable diseases, injuries and deaths. Design Decision modelling using Markov chains compared costs and effects over 5 years. Setting The analysis was from the perspective of the National Health Service (NHS) in England and Wales. Participants The model considered the licensed population for nalmefene, specifically adults with both alcohol dependence and high/very high DRLs, who do not require immediate detoxification and who continue to have high/very high DRLs after initial assessment. Data sources We modelled treatment effect using data from three clinical trials for nalmefene (ESENSE 1 (NCT00811720), ESENSE 2 (NCT00812461) and SENSE (NCT00811941)). Baseline characteristics of the model population, treatment resource utilisation and utilities were from these trials. We estimated the number of alcohol-attributable events occurring at different levels of alcohol consumption based on published epidemiological risk-relation studies. Health-related costs were from UK sources. Main outcome measures We measured incremental cost per quality-adjusted life year (QALY) gained and number of alcohol-attributable harmful events avoided. Results Nalmefene in combination with psychosocial support had an incremental cost-effectiveness ratio (ICER) of £5204 per QALY gained, and was therefore cost-effective at the £20 000 per QALY gained decision threshold. Sensitivity analyses showed that the conclusion was robust. Nalmefene plus psychosocial support led to the avoidance of 7179 alcohol-attributable diseases/injuries and 309 deaths per 100 000 patients compared to psychosocial support alone over the course of 5 years. Conclusions Nalmefene can be seen as a cost-effective treatment for alcohol dependence, with substantial public health benefits. Trial registration numbers This cost-effectiveness analysis was developed based on data from three randomised clinical trials: ESENSE 1 (NCT00811720), ESENSE 2 (NCT00812461) and SENSE (NCT00811941).

Sterile inflammation resulting in alcoholic hepatitis (AH) occurs unpredictably after many years of excess alcohol intake. The factors responsible for the development of AH are not known but mitochondrial damage with loss of mitochondrial function are common features. Hcar2 is a G-protein coupled receptor which is activated by β-hydroxybutyrate (BHB). We aimed to determine the relevance of the BHB-Hcar2 pathway in alcoholic liver disease. We tested if loss of BHB production can result in increased liver inflammation. We further tested if BHB supplementation is protective in AH through interaction with Hcar2, and analyzed the immune and cellular basis for protection. Humans with AH have reduced hepatic BHB, and inhibition of BHB production in mice aggravated ethanol-induced AH, with higher plasma alanine aminotransferase levels, increased steatosis and greater neutrophil influx. Conversely supplementation of BHB had the opposite effects with reduced alanine aminotransferase levels, reduced steatosis and neutrophil influx. This therapeutic effect of BHB is dependent on the receptor Hcar2. BHB treatment increased liver Il10 transcripts, and promoted the M2 phenotype of intrahepatic macrophages. BHB also increased the transcriptional level of M2 related genes in vitro bone marrow derived macrophages. This skewing towards M2 related genes is dependent on lower mitochondrial membrane potential (Δψ) induced by BHB. Collectively, our data shows that BHB production during excess alcohol consumption has an anti-inflammatory and hepatoprotective role through an Hcar2 dependent pathway. This introduces the concept of metabolite-based therapy for AH. Alcoholic hepatitis is a life-threatening condition with no approved therapy that occurs unexpectedly in people who consume excess alcohol. The liver makes many metabolites, and we demonstrate that loss of one such metabolite β-hydroxybutyrate occurs in patients with alcoholic hepatitis. This loss can increase alcohol-induced liver injury, and β-hydroxybutyrate can protect from alcohol-induced liver injury via a receptor on liver macrophages. This opens the possibility of metabolite-based therapy for alcoholic hepatitis. Copyright © 2018 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

The present study examined familial risk and protective factors as moderators of parents allowing their adolescent children to drink at home on longitudinal alcohol involvement trajectories. A total of 772 community adolescents and their parents provided data beginning in 1989 and at four subsequent time points over 15 years; Black adolescents were intentionally oversampled (50% at baseline). Outcomes related to allowing adolescents to drink at home depended on family structure: Adolescents from intact families who were allowed to drink at home showed the lowest levels of alcohol use and problems over time, whereas those from nonintact families who were allowed to drink at home showed the highest levels of involvement. These results controlled for family history of alcohol problems, consistent parenting styles, and demographic characteristics. Results suggest that allowing adolescents to drink at home is neither inherently protective nor risky but depends on the family context. Implications for the development of adolescent alcohol involvement are discussed.
Commonalities and distinctions among mechanisms of addiction to alcohol and other drugs

Alcohol abuse is comorbid with abuse of many other drugs, some with similar pharmacology and others quite different. This leads to the hypothesis of an underlying, unitary dysfunctional neurobiological basis for substance abuse risk and consequences. In this review, we discuss commonalities and distinctions of addiction to alcohol and other drugs. We focus on recent advances in pre-clinical studies using rodent models of drug self-administration. While there are specific behavioral and molecular manifestations common to alcohol, psychostimulant, opioid, and nicotine dependence, attempts to propose a unifying theory of the addictions inevitably face details where distinctions are found among classes of drugs. For alcohol, versus other drugs of abuse, we discuss and compare advances in: 1) neurocircuitry important for the different stages of drug dependence; 2) transcriptomics and genetical genomics; and 3) enduring effects. We note in particular the contributions of behavioral genetics and animal models: discussions of progress specifically relevant to treatment development can be found in the accompanying review (Karoly et al, this issue).

Animal studies suggest that the gut-brain peptide ghrelin plays an important role in the neurobiology of alcohol dependence (AD). Human studies show an effect of alcohol on ghrelin levels and a correlation between ghrelin levels and alcohol craving in alcoholics. This investigation consisted of two studies. Study 1 was a 12-week study with alcohol-dependent subjects, where plasma ghrelin determinations were assessed four times (T0-T3) and related to alcohol intake and craving [Penn Alcohol Craving Score (PACS) and Obsessive Compulsive Drinking Scale (OCDS)]. Serum growth hormone (GH) levels and assessment of the nutritional/metabolic status were also performed. Study 2 was a pilot case-control study to assess ghrelin gene polymorphisms (Arg51Gln and Leu72Met) in alcohol-dependent individuals. Study 1 showed no significant differences in ghrelin levels in the whole sample, while there was a statistical difference for ghrelin between non-abstinent and abstinent subjects. Baseline ghrelin levels were significantly and positively correlated with the PACS score at T1 and with all craving scores both at T2 and T3 (PACS, OCDS, obsessive and compulsive OCDS subscores). In Study 2, although there was a higher frequency of the Leu72Met ghrelin gene polymorphism in alcohol-dependent individuals, the distribution between healthy controls and alcohol dependent individuals was not statistically significant. This investigation suggests that ghrelin is potentially able to affect alcohol-seeking behaviors, such as alcohol drinking and craving, representing a new potential neuropharmacological target for AD.

Acute withdrawal, protracted abstinence and negative affect in alcoholism: Are they linked?
Heilig, M.; Egli, M.; Crabbe, J.C.; Becker, H.C.
2012-01-01
The role of withdrawal-related phenomena in development and maintenance of alcohol addiction remains under debate. A “self-medication” framework postulates that emotional changes are induced by a history of alcohol use, persist into abstinence, and are a major factor in maintaining alcoholism. This view initially focused on negative emotional states during early withdrawal: these are pronounced, occur in the vast majority of alcohol dependent patients, and are characterized by depressed mood and elevated anxiety. This concept lost popularity with the realization that, in most patients, these symptoms abate over 3 – 6 weeks of abstinence, while relapse risk persists long beyond this period. More recently, animal data have established that a prolonged history of alcohol dependence induces more subtle neuroadaptations. These confer altered emotional processing that persists long into protracted abstinence. The resulting behavioral phenotype is characterized by excessive voluntary alcohol intake and increased behavioral sensitivity to stress. Emerging human data support the clinical relevance of negative emotionality for protracted abstinence and relapse. These developments prompt a series of research questions: 1) Are processes observed during acute withdrawal, while transient in nature, mechanistically related to those that remain during protracted abstinence? 2) Is susceptibility to negative emotionality in acute withdrawal in part due to heritable factors, similar to what animal models have indicated for susceptibility to physical aspects of withdrawal? 3) To what extent is susceptibility to negative affect that persists into protracted abstinence heritable?

Impulsivity and alcohol drinking are both considered as important predictors of unintentional as well as intentional injuries. However, relationships of impulsivity with risky behaviors and a history of accidents have not been investigated in alcohol dependence. The aim of this study was to analyze relationships between the frequency of risky behaviors and level of behavioral as well as cognitive impulsivity in alcohol-dependent patients. By means of Barratt’s Impulsiveness Scale (BIS) and stop-signal task, the levels of cognitive and behavioral impulsivity among 304 alcohol-dependent patients were measured. Also, patients were asked to answer questions from the Short Inventory of Problems applying to risky behaviors and accidents after alcohol drinking. In addition participants completed a questionnaire to assess frequency of other behaviors from the analyzed spectrum (use of other drugs, driving or aggressive behavior after alcohol drinking). The statistical analysis revealed a significant association between impulsivity and frequency of risky behaviors in alcohol-dependent patients. Individuals with higher scores in BIS behaved more frequently in a risky way and had significantly more accidents after alcohol drinking. The association with risky behaviors was strongest for non-planning and attentional impulsivity subscales, whereas frequency of accidents was particularly associated with motor impulsivity. A multivariate analysis revealed that impulsivity was the most important predictor of risky behaviors, but did not significantly predict a history of accidents. Our study confirms that impulsivity is an important correlate of risky behaviors in alcohol-dependent individuals, along with global psychopathology and severity of alcohol dependence. PMID:23246707
Paternal alcoholism and offspring ADHD problems: a children of twins design.

2009-02-01
A recent Children-of-Female-Twin design suggests that the association between maternal alcohol use disorder and offspring ADHD is due to a combination of genetic and environmental factors, such as prenatal nicotine exposure. We present here a complementary analysis using a Children-of-Male-Twin design examining the association between paternal alcoholism and offspring attention deficit hyperactivity problems (ADHP). Children-of-twins design: offspring were classified into 4 groups of varying genetic and environmental risk based on father and co-twin's alcohol dependence status. Univariate results are suggestive of a genetic association between paternal alcohol dependence and broadly defined offspring ADHP. Specifically, offspring of male twins with a history of DSM-III-R alcohol dependence, as well as offspring of non-alcohol dependent monozygotic twins whose co-twin was alcohol dependent, were significantly more likely to exhibit ADHP than control offspring. However, multivariate models show maternal variables independently predicting increased risk for offspring ADHP and significantly decreased support for a genetic mechanism of parent-to-child transmission. In support of earlier work, maternal variables (i.e., maternal ADHD and prenatal exposure) were strongly associated with child ADHP; however, the role of paternal alcohol dependence influences was not definitive. While genetic transmission may be important, the association between paternal alcohol dependence and child ADHP is more likely to be indirect and a result of several pathways.

The aim of this study was to evaluate the potential contributing factors such as alexithymia, emotion regulation and difficulties in emotion regulation, positive/negative affects and clinical factors including severity of alcohol dependence and depression connected to high suicidality in alcohol-dependent outpatients. 205 alcohol-dependent outpatients and 100 normal controls completed the demographic questionnaire, the Persian version of the Toronto Alexithymia Scale (FTAS-20), the Difficulties in Emotion Regulation Scale (DERS), the Emotion Regulation Questionnaire (ERQ), the Positive/Negative Affect Scales, the Alcohol Use Disorders Identification Test (AUDIT), and the Beck Depression Inventory-II (BDI-II). The suicidal risk was assessed using the Scale for Suicide Ideation (SSI) and history taking. Alcohol-dependent outpatients showed higher means in alexithymia, difficulties in emotion regulation, suppression subscale, negative affect, and suicide ideation than normal controls. Logistic regression analysis revealed that negative affect, duration of alcohol use, externally-oriented thinking, and severity of alcohol dependence explained lifetime suicide attempts. Depression, impulsivity, severity of alcohol dependence, reappraisal (reversely), externally-oriented thinking, difficulties engaging in goal-directed behaviors, and negative affect significantly predicted the suicidal risk. The findings may constitute useful evidence of the relevancies of alexithymia, emotion regulation, emotion regulation difficulties, and affects to suicidality in alcoholic patients.

Objective: Variations in the genes encoding alcohol dehydrogenase (ADH) enzymes are associated with both alcohol consumption and dependence in multiple populations. Additionally, some environmental factors have been recognized as modifiers of these relationships. This study examined the modifying effect of religious involvement on relationships between ADH gene variants and alcohol consumption–related phenotypes. Method: Subjects were African American, European American, and Hispanic American adults with lifetime exposure to alcohol (N = 7,716; 53% female) from the Collaborative Study on the Genetics of Alcoholism. Genetic markers included ADH1B-rs1229984, ADH1B-rs2066702, ADH1C-rs698, ADH4-rs1042364, and ADH4-rs1800759. Phenotypes were maximum drinks consumed in a 24-hour period and total number of alcohol dependence symptoms according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Religious involvement was defined by self-reported religious services attendance. Results: Both religious involvement and ADH1B-rs1229984 were negatively associated with the number of maximum drinks consumed and the number of lifetime alcohol dependence symptoms endorsed. The interactions of religious involvement with ADH1B-rs2066702, ADH1C-rs698, and ADH4-rs1042364 were significantly associated with maximum drinks and alcohol dependence symptoms. Risk variants had weaker associations with maximum drinks and alcohol dependence symptoms as a function of increasing religious involvement. Conclusions: This study provided initial evidence of a modifying effect for religious involvement on relationships between ADH variants and maximum drinks and alcohol dependence symptoms.

Objective. To verify the association between violence and alcohol dependence syndrome in sample populations. Method. Population-wide survey with multistage probabilistic sample. 3,744 individuals of both genders, aged from 15 to 75 years, were interviewed from the cities of São Paulo and Rio de Janeiro using the Composite International Diagnostic Interview (CIDI 2.1). Results. In both cities, alcohol dependence was associated with the male gender, having suffered violence related to criminality, and having suffered familial violence. In both cities, urban violence, in more than 50% of cases, and familial violence, in more than 90% of cases, preceded alcohol dependence. The reoccurrence of traumatic events occurred in more than half of individuals dependent on alcohol. In São Paulo, having been diagnosed with PTSD is associated with violence revictimization (P = 0.014; Odds = 3.33). Conclusion. Alcohol dependence syndrome is complexly related to urban and familial violence in the general population. Violence frequently precedes alcoholism, but this relationship is dependent on residence and traumatic events. This vicious cycle contributes to perpetuating the high rates of alcoholism and violence in the cities. Politicians ordering the reduction of violence in the large metropolises can, potentially, reduce alcoholism and contribute to the break of this cycle. PMID:26000304

Eighty males with alcohol dependence were examined using the Hindi version of Diagnostic Interview for Genetic Studies, the International Classification of Disease-10 th Edition Personality Disorder Examination, Alcohol Use Disorder Identification Test for alcohol use, global assessment of functioning, blood sampling electrocardiogram, and ultrasonogram. Eighty-seven percent had a comorbid Axis I or an Axis II psychiatric disorder, over 78% had nicotine dependence, and 56% had comorbid Axis II disorder, antisocial personality being the most common. Gamma glutamyl transpeptidase levels were significantly associated with comorbidity. High comorbidity of Axis I psychiatric disorders was found among persons with alcohol dependence. Axis II disorders were also present.

Research on alcohol use depends heavily on the validity of self-reported drinking. The present paper presents data from 647 days of self-monitoring with a transdermal alcohol sensor by 60 young adults. We utilized a biochemical measure, transdermal alcohol assessment with the WrisTAS, to examine the convergent validity of three approaches to collecting daily self-report drinking data: experience sampling, daily morning reports of the previous night, and 1-week timeline follow-back (TLFB) assessments. We tested associations between three pharmacokinetic indices (peak concentration, area under the curve (AUC), and time to reach peak concentration) derived from the transdermal alcohol signal and within- and between- person variation in alcohol dependence symptoms. The WrisTAS data corroborated 85.74% of self-reported drinking days based on the experience sampling data. The TLFB assessment and combined experience sampling and morning reports agreed on 87.27% of drinking days. Drinks per drinking day did not vary as a function of wearing or not wearing the sensor; this indicates that participants provided consistent reports of their drinking regardless of biochemical verification. In respect to self-reported alcohol dependence symptoms, the AUC of the WrisTAS alcohol signal was associated with dependence symptoms at both the within- and between- person level. Furthermore, alcohol dependence symptoms at baseline predicted drinking episodes characterized in biochemical data by both higher peak alcohol concentration and faster time to reach peak concentration. The results support the validity of self-report alcohol data, provide empirical data useful for optimal design of daily process sampling, and provide an initial demonstration of the use of transdermal alcohol assessment to characterize drinking dynamics associated with risk for alcohol dependence.

Background The dynorphin (DYN)/κ-opioid receptor (KOR) system undergoes neuroadaptations following chronic alcohol exposure that promote excessive operant self-administration and negative affective-like states; however, the exact mechanisms are unknown. The present studies tested the hypothesis that an upregulated DYN/KOR system mediates excessive alcohol self-administration that occurs during withdrawal in alcohol-dependent rats by assessing DYN A peptide expression and KOR function, in combination with site-specific pharmacological manipulations. Methods Male Wistar rats were trained to self-administer alcohol using operant behavioral strategies and subjected to intermittent alcohol vapor- or air-exposure. Changes in self-administration were assessed by pharmacological challenges during acute withdrawal. In addition, 22-kHz ultrasonic vocalizations were utilized to measure negative affective-like states. Immunohistochemical techniques assessed DYN A peptide expression and [35S]GTPγS coupling assays were performed to assess KOR function. Results Alcohol-dependent rats displayed increased alcohol self-administration, negative affective-like behavior, DYN A-like immunoreactivity and KOR signaling in the amygdala compared to non-dependent controls. Site-specific infusions of a KOR antagonist selectively attenuated self-administration in dependent rats whereas, a MOR/DOR antagonist cocktail selectively reduced self-administration in non-dependent rats. A MOR antagonist/partial KOR agonist attenuated self-administration in both cohorts. Conclusion Increased DYN A and increased KOR signaling could set the stage for a `one-two punch' during withdrawal that drives excessive alcohol consumption in alcohol-dependence. Importantly, intra-CeA pharmacological challenges functionally confirmed a DYN/KOR system involvement in the escalated alcohol self-administration. Together, the DYN/KOR system is heavily dysregulated in alcohol dependence and contributes to the excessive alcohol consumption during withdrawal. PMID:23611261

Persistent cases of alcohol and nicotine dependence are associated with considerable morbidity and mortality, and are predicted by childhood maltreatment and personality disorders. Our aim was to test whether personality disorders (individually or conjointly) mediate the relationship between childhood maltreatment and the persistence of dependence. Personality disorders, modeled dimensionally, were tested as mediators of the relationship between childhood maltreatment and the 3-year persistence of alcohol and nicotine dependence in participants in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) who had current alcohol and nicotine dependence in their baseline interview. Individual personality disorders were assessed in separate models. Then, those that were significant were examined jointly in multiple mediator models to determine their total and unique effects. A large, nationally representative US survey. Participants ≥ 18 years who completed baseline and 3-year follow-up NESARC interviews who had baseline alcohol dependence (n = 1172; 68% male) or nicotine dependence (n = 4017; 52.9% male). Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS-IV) measures of childhood maltreatment, personality disorders and alcohol/nicotine dependence. Individual models indicated that many personality disorders mediated the relationship between childhood maltreatment and the 3-year persistence of alcohol and nicotine dependence (each explaining 6-46% of the total effect, Ps < 0.05). In multiple mediator models, borderline and antisocial symptoms remained significant mediators, each explaining 20-37% of the total effect (Ps < 0.01). Personality disorder symptoms (especially borderline and antisocial) help explain the association between childhood maltreatment and persistent alcohol and nicotine dependence. © 2016 Society for the Study of Addiction.

Emerging evidence indicates that dysfunctional glutamate neurotransmission is critical in the initiation and development of alcohol and drug dependence. Alcohol consumption induced downregulation of glutamate transporter 1 (GLT-1) as reported in previous studies from our laboratory. Glutamate is the major excitatory neurotransmitter in the brain, which acts via interactions with several glutamate receptors. Alcohol consumption interferes with the glutamatergic signal transmission by altering the functions of these receptors. Among the glutamatergic receptors involved in alcohol-drinking behavior are the metabotropic receptors such as mGluR1/5, mGluR2/3, and mGluR7, as well as the ionotropic receptors, NMDA and AMPA. Preclinical studies using agonists and antagonists implicate these glutamatergic receptors in the development of alcohol use disorder (AUD). Therefore, the purpose of this review is to discuss the neurocircuitry involving glutamate transmission in animals exposed to alcohol and further outline the role of metabotropic and ionotropic receptors in the regulation of alcohol-drinking behavior. This review provides ample information about the potential therapeutic role of glutamatergic receptors for the treatment of AUD. PMID:28242339
The Epigenetic Landscape of Alcoholism

Alcoholism is a complex psychiatric disorder that has a multifactorial etiology. Epigenetic mechanisms are uniquely capable of accounting for the multifactorial nature of the disease in that they are highly stable and are affected by environmental factors, including alcohol itself. Chromatin remodeling causes changes in gene expression in specific brain regions contributing to the endophenotypes of alcoholism such as tolerance and dependence. The epigenetic mechanisms that regulate changes in gene expression observed in addictive behaviors respond not only to alcohol exposure, but also to comorbid psychopathology such as the presence of anxiety and stress. This review summarizes recent developments in epigenetic research that may play a role in alcoholism. We propose that pharmacologically manipulating epigenetic targets, as demonstrated in various preclinical models, holds great therapeutic potential in the treatment and prevention of alcoholism.

The Lesch alcoholism typology – psychiatric and psychosocial treatment approaches
Schlaff, Golda; Walter, Henriette; Lesch, Otto Michael
2011-01-01
In the past three decades, researchers have been attempting to replace the obsolete concept of homogeneity of alcohol dependence, by classifying these patients into specific heterogeneous subtypes. Based on 30 years of experience and research, the Lesch Typology has proved to be very useful in clinical daily routine. The aim of the Lesch Typology is to provide targeted subtype-specific treatments to patients, thereby increasing their probability of long-term abstinence and hence improving their prognosis. The Lesch Typology is based on data from a longitudinal prospective study (with follow ups even 19 years later) on alcohol dependent patients (n=436). By observing the long term development of these patients, four distinct courses could be identified. In the meantime, a computerized version of the Lesch Typology had been created and translated into many languages, and is currently being employed in numerous psychiatric institutions while assisting clinicians in quickly determining a patient’s subtype (www.lat-online.at). Based on the patients’ drinking patterns and origin of substance craving, hence according to the Lesch Typology, four subtypes of alcohol dependent patients can be distinguished: 1. the “allergy model” (craving caused by alcohol); 2. the “conflict resolution and anxiety model” (craving caused by stress); 3. the “depressive model” (craving caused by mood); and 4. the “conditioning model” (craving caused by compulsion). Pharmacological treatments are not always the most effective way of preventing relapses in alcohol dependent patients. Many times, a combination with psychosocial as well as psychotherapeutic approaches is necessary and essential for helping patients to stay sober. Depending on the patient’s Lesch Type, certain therapeutic approaches are more appropriate and subsequently lead to better results and higher chances of lasting abstinence. PMID:24713718

Alcohol-dependence (AD) is a ravaging public health and social problem. AD diagnosis depends on questionnaires and some biomarkers, which lack specificity and sensitivity, however, often leading to less precise diagnosis, as well as delaying treatment. This represents a great burden, not only on AD individuals but also on their families. Metabolomics using nuclear magnetic resonance spectroscopy (NMR) can provide novel techniques for the identification of novel biomarkers of AD. These putative biomarkers can facilitate early diagnosis of AD. To identify novel biomarkers able to discriminate between alcohol-dependent, non-AD alcohol drinkers and controls using metabolomics. Urine samples were collected from 30 alcohol-dependent persons who did not yet start AD treatment, 54 social drinkers and 60 controls, who were then analysed using NMR. Data analysis was done using multivariate analysis including principal component analysis (PCA) and orthogonal partial least square-discriminate analysis (OPLS-DA), followed by univariate and multivariate logistic regression to develop the discriminatory model. The reproducibility was done using intraclass correlation coefficient (ICC). The OPLS-DA revealed significant discrimination between AD and other groups with sensitivity 86.21%, specificity 97.25% and accuracy 94.93%. Six biomarkers were significantly associated with AD in the multivariate logistic regression model. These biomarkers were cis-aconitic acid, citric acid, alanine, lactic acid, 1,2-propanediol and 2-hydroxyisovaleric acid. The reproducibility of all biomarkers was excellent (0.81-1.0). This study revealed that metabolomics analysis of urine using NMR identified AD novel biomarkers which can discriminate AD from social drinkers and controls with high accuracy.

Chronic and excessive alcohol drinking lead to alcohol dependence and loss of control over alcohol consumption, with serious detrimental health consequences. Chronic alcohol exposure followed by protracted withdrawal causes profound alterations in the brain reward system that leads to marked changes in reinforcement mechanisms and motivational state. These long-lasting neuroadaptations are thought to contribute to the development of cravings and relapse. The nucleus accumbens (NAcc), a central component of the brain reward system, plays a critical role in alcohol-induced neuroadaptive changes underlying alcohol-seeking behaviors. Here we review the findings that chronic alcohol exposure produces long-lasting neuroadaptive changes in various ion channels that govern intrinsic membrane properties and neuronal excitability, as well as excitatory and inhibitory synaptic transmission in the NAcc that underlie alcohol-seeking behavior during protracted withdrawal.

Several studies have correlated the use of one drug with that of another drug; however, whether dependence on one drug is associated with dependence on another drug, independent of any use/use association, is unclear. We asked 196 randomly-selected subjects the DSM-IV criteria for dependence as applied to alcohol, caffeine, and nicotine. Among ever users, the severity of alcohol vs nicotine dependence and alcohol vs caffeine dependence was related, but this relationship was weak (r = .22 & .31). Nicotine and caffeine dependence were not correlated. These results fail to confirm theories of commonality that hypothesize dependence on one drug predisposes to dependence on another drug.

Neuronal activity dependent pentraxin (Narp) interacts with α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA) glutamate receptors to facilitate excitatory synapse formation by aggregating them at established synapses. Alcohol is well-characterized to influence central glutamatergic transmission, including AMPA receptor function. Herein, we examined the influence of injected and ingested alcohol upon Narp protein expression, as well as basal Narp expression in mouse lines selectively bred for high blood alcohol concentrations under limited access conditions. Alcohol up-regulated accumbens Narp levels, concomitant with increases in levels of the GluR1 AMPA receptor subunit. However, accumbens Narp or GluR1 levels did not vary as a function of selectively bred genotype. We next employed a Narp knock-out (KO) strategy to begin to understand the behavioral relevance of alcohol-induced changes in protein expression in several assays of alcohol reward. Compared to wild-type mice, Narp KO animals: fail to escalate daily intake of high alcohol concentrations under free-access conditions; shift their preference away from high alcohol concentrations with repeated alcohol experience; exhibit a conditioned place-aversion in response to the repeated pairing of 3 g/kg alcohol with a distinct environment and fail to exhibit alcohol-induced locomotor hyperactivity following repeated alcohol treatment. Narp deletion did not influence the daily intake of either food or water, nor did it alter any aspect of spontaneous or alcohol-induced motor activity, including the development of tolerance to its motor-impairing effects with repeated treatment. Taken together, these data indicate that Narp induction, and presumably subsequent aggregation of AMPA receptors, may be important for neuroplasticity within limbic subcircuits mediating or maintaining the rewarding properties of alcohol.

Pathways from alcoholism to recovery are documented; less often are those from drug addiction to alcoholism. Biographical approaches allow analyzing how people change their uses and talk about their trajectories of recovery. Three hundred and forty-one people (34% women) in the Paris area were questioned on their trajectories with a biographical questionnaire. Some open questions were aimed to understand the connection they made between events in their lives, how recovered they felt and what they considered strengths or obstacles. All the participants had stopped at least one product. Their mean age was 43, and 26% were over 50. How can the differences between one substance addicts and dual abusers be explained? Can we hypothesize a better result for the patients with a single dependence to alcohol in their lives for the following two reasons? (1) They could really be taken in charge for their alcoholism whereas the dual abusers mostly receive cared for their illicit drug problems with an under estimation of their problem with alcohol. In this case, they turn to alcohol after weaning themselves from their drug dependence so as to return to a social consumption, especially when they are given an opiate treatment. (2) Conversely could we suggest that the dual substance abusers had different trajectories from their childhood (more adverse events, more social difficulties, mental health problems), and that this accumulation explains their skipping from one substance or behaviour to another without any real recovery for decades? All respondents were polydrug users. Eighty-two had been dependent mainly on alcohol. One hundred and twenty-one people had been drug addicts (mostly heroin), which they had stopped on average ten years before the survey. The last group included 138 persons who had been heroin or cocaine addicts and alcoholics in their lives, a third of whom had been dependent on alcohol before their drug addiction (35%), a tenth on both at the same time (10%) and more than half of the users (55%) had turned from drug addiction to alcoholism. The group concerning alcohol dependence includes the oldest participants, on average 49.7, and 55% of them were abstinent at the survey. Conversely, the group "with no alcohol dependence" had mainly turned to opiate treatments. Their histories in dependence and in various social statuses also showed a longer duration out of employment, in sickness or invalidity, or in prison, for the drug dependents as opposed to the "mainly" alcoholics. The population with dual substance abuse experienced twice as many adverse childhood events as the others (P<0.005): it was the case for 19.5% in "mainly alcohol" dependence compared to 38.4% in dual abuse. The recovery capital gave a mean score of 7.56±2.35 (median 7). A score below 6 was considered low. The score was significantly different according to the dependence groups: while 7.3% of "mainly alcohol" dependents had a score below 6, this was the case for 30.4% of the dual group (with alcohol and drugs), and 19% for the "mainly drug dependence" group. Controlling ages, sexes and groups of dependence in a logistic regression, the risk of having a recovery capital below six was more than four times higher for the dual dependents as opposed to the "mainly alcohol" dependents. Some people stay for decades in drug addiction centers switching from one dependence to another. Their alcohol drinking should be addressed earlier to prevent them from turning to drinking excessively in order to wean themselves from their drug addiction. Copyright © 2016 L'Encéphale, Paris.

The human dopamine receptor 2 gene DRD2 plays a central role in susceptibility to Alcohol Dependence Syndrome (ADS). The aim of this study was to evaluate 3 single nucleotide polymorphisms: D2 (rs1076560), Tag1D (rs1800498), Tag1B (rs1079597) located in dopamine receptor 2 DRD2 gene and its role in alcohol dependence. DNA was provided from alcohol dependent (AD) patients (n=171) and healthy control subjects (n=160) all of Polish descent. The history of alcoholism was obtained using the Polish version of the SSAGA (Semi-Structured Assessment for the Genetics of Alcoholism). We conducted case-control association study and transmission disequilibrium test (TDT). Samples were genotyped using real-time PCR method. We did not confirm the association between studied polymorphisms and alcohol dependence syndrome. TDT reveled an adequate transmission of both alleles in the group of alcohol families. The lack of association of studied polymorphisms and ADS does not preclude its participation in the pathogenesis. Further research is needed to determine the actual contribution of DRD2 gene in the pathogenesis of alcoholism.

Bipolar disorder (BD), especially BD-II, is frequently comorbid with alcohol dependence. Because BD-II and alcohol dependence are neurodegenerative disorders, agents with anti-inflammatory and neurotrophic effects might provide effective therapy. We investigated whether add-on memantine to regular valproic acid treatment ameliorated clinical symptoms, reduced alcohol use, and cytokine levels, and increased plasma brain-derived neurotrophic factor (BDNF) in BD-II patients with comorbid alcohol dependence. In a single-arm 12-week clinical trial, BD-II patients with comorbid alcohol dependence (n = 45) undergoing regular valproic acid treatments were given add-on memantine (5 mg/d). Symptom severity, alcohol use, cytokine (plasma tumor necrosis factor-α and C-reactive protein [CRP], transforming growth factor-β1 [TGF-β1], interleukin-8 [IL-8], IL-10), and plasma BDNF levels were regularly assessed. Mean within-group decreases in Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) scores, alcohol use, CRP, BDNF, and IL-8 levels were significantly different from baseline after 12 weeks of treatment. We found no significant correlation between alcohol use levels and changes in HDRS or YMRS scores. The correlation between reduced alcohol use and reduced TGF-β1 level was significant (B = 0.003, p = 0.019). BD-II comorbid with alcohol dependence might benefit from add-on memantine treatment, which significantly reduced clinical severity, alcohol use, and plasma cytokine levels, and increased BDNF levels.

To explore the abnormal intrinsic functional hubs in alcohol dependence using voxelwise degree centrality analysis approach, and their relationships with clinical features. Twenty-four male alcohol dependence subjects free of medicine (mean age, 50.21±9.62 years) and 24 age- and education-matched male healthy controls (mean age, 50.29±8.92 years) were recruited. The alcohol use disorders identification test and the severity of alcohol dependence questionnaire (SADQ) were administered to assess the severity of alcohol craving. Voxelwise degree centrality approach was used to assess the abnormal intrinsic functional hubs features in alcohol dependence. Simple linear regression analysis was performed to investigate the relationships between the clinical features and abnormal intrinsic functional hubs. Compared with healthy controls, alcohol dependence subjects exhibited significantly different degree centrality values in widespread left lateralization brain areas, including higher degree centrality values in the left precentral gyrus (BA 6), right hippocampus (BA 35, 36), and left orbitofrontal cortex (BA 11) and lower degree centrality values in the left cerebellum posterior lobe, bilateral secondary visual network (BA 18), and left precuneus (BA 7, 19). SADQ revealed a negative linear correlation with the degree centrality value in the left precentral gyrus ( R 2 =0.296, P =0.006). The specific abnormal intrinsic functional hubs appear to be disrupted by alcohol intoxication, which implicates at least three principal neural systems: including cerebellar, executive control, and visual cortex, which may further affect the normal motor behavior such as an explicit type of impaired driving behavior. These findings expand our understanding of the functional characteristics of alcohol dependence and may provide a new insight into the understanding of the dysfunction and pathophysiology of alcohol dependence.

Identifying novel treatments that facilitate extinction learning could enhance cue-exposure therapy and reduce high relapse rates in alcoholics. Activation of mGlu 5 receptors in the infralimbic prefrontal cortex (IL-PFC) facilitates learning during extinction of cue-conditioned alcohol-seeking behavior. Small-conductance calcium-activated potassium (K Ca 2) channels have also been implicated in extinction learning of fear memories, and mGlu 5 receptor activation can reduce K Ca 2 channel function. Using a combination of electrophysiological, pharmacological, and behavioral approaches, this study examined K Ca 2 channels as a novel target to facilitate extinction of alcohol-seeking behavior in rats. This study also explored related neuronal and synaptic mechanisms within the IL-PFC that underlie mGlu 5 -dependent enhancement of extinction learning. Using whole-cell patch-clamp electrophysiology, activation of mGlu 5 in ex vivo slices significantly reduced K Ca 2 channel currents in layer V IL-PFC pyramidal neurons, confirming functional downregulation of K Ca 2 channel activity by mGlu 5 receptors. Additionally, positive modulation of K Ca 2 channels prevented mGlu 5 receptor-dependent facilitation of long-term potentiation in the IL-PFC. Systemic and intra-IL-PFC treatment with apamin (K Ca 2 channel allosteric inhibitor) significantly enhanced extinction of alcohol-seeking behavior across multiple extinction sessions, an effect that persisted for 3 weeks, but was not observed after apamin microinfusions into the prelimbic PFC. Positive modulation of IL-PFC K Ca 2 channels significantly attenuated mGlu 5 -dependent facilitation of alcohol cue-conditioned extinction learning. These data suggest that mGlu 5 -dependent facilitation of extinction learning and synaptic plasticity in the IL-PFC involves functional inhibition of K Ca 2 channels. Moreover, these findings demonstrate that K Ca 2 channels are a novel target to facilitate long-lasting extinction of alcohol-seeking behavior. SIGNIFICANCE STATEMENT Alcohol use disorder is a chronic relapsing disorder that is associated with compulsive alcohol-seeking behavior. One of the main causes of alcohol relapse is the craving caused by environmental cues that are associated with alcohol. These cues are formed by normal learning and memory principles, and the understanding of the brain mechanisms that help form these associations can lead to the development of drugs and/or behavior therapies that reduce the impact that these cues have on relapse in alcoholics.

[Addictive behavior in the elderly].

Alcohol and drug abuse are the two main addictions in the elderly subject. Prevalence of alcohol dependency is 14% in those over 65 years of age and 17% in elderly psychiatric patients. The distribution of alcoholism between the sexes becomes equal with age. After 65 years of age, the sex-ratio is 1 female to 1.3 male subjects. The elderly alcoholic population consists of both subjects having become alcoholics at a young age and those in whom alcoholic behaviour appeared at a late age. In one third of elderly alcoholics such dependency appeared after 60 years of age. The main risk factors for alcoholism in the elderly subject are lonliness, death of the spouse and the presence of an invalid or bedridden spouse. In the elderly, tolerance to and dependence on alcohol are rare and appear late. Somatic complications are particularly severe (cirrhosis, liver cancer, gastritis, acute pancreatitis and myocardial involvement). Psychiatric complications include anxiety, depression and especially suicide. Alcoholism is the third most frequent cause of organic cerebral dementia, following Alzheimer disease and vascular dementia. Drug dependency is very often linked to alcoholism and consists of tranquillizers and less often of antalgics.

This study examined the association between alcohol use problem severity, defined by number of DSM-IV alcohol Abuse and Dependence symptoms and frequency of alcohol use, and problem behavior engagement among Mexican students. A confidential survey was administered to 1229 students in grades 7–12 at two schools in a northern border city in Mexico. Youths were categorized into five groups based on their alcohol use frequency and symptoms of DSM-IV alcohol Abuse and Dependence, specifically: no lifetime alcohol use, lifetime alcohol use but none in the past year, past year alcohol use, one or two alcohol Abuse or Dependence symptoms, and three or more alcohol Abuse or Dependence symptoms. The association between five levels of alcohol use problem severity and three problem behaviors, lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble, was examined using chi-square or Fisher’s exact tests. Several alcohol use problem severity categories were significantly different with respect to rates of lifetime marijuana use, lifetime sexual intercourse, and past year arrest/law trouble. Higher alcohol use problem severity was associated with greater endorsement of problem behaviors. Knowing about variations in adolescent alcohol use and alcohol problems may be instrumental in determining if youths are also engaging in a range of other risk behaviors. Considering varying levels of alcohol use and alcohol problems is important for effective targeted prevention and treatment interventions. PMID:22840814

The purpose of this paper is to supply a narrative review of the concepts, history, functions, methods, development and theoretical bases for the use of halfway houses for patients with mental disorders, and their correlations, for the net construction of chemical dependence model. This theme, in spite of its relevance, is still infrequently explored in the national literature. The authors report international and national uses of this model and discuss its applicability for the continuity of services for alcohol dependents. The results suggest that this area is in need of more attention and interest for future research. PMID:19061008
In Utero Alcohol Exposure, Epigenetic Changes, and Their Consequences
Ungerer, Michelle; Knezovich, Jaysen; Ramsay, Michele

Exposure to alcohol has serious consequences for the developing fetus, leading to a range of conditions collectively known as fetal alcohol spectrum disorders (FASD). Most importantly, alcohol exposure affects the development of the brain during critical periods of differentiation and growth, leading to cognitive and behavioral deficits. The molecular mechanisms and processes underlying the teratogenic effects of alcohol exposure remain poorly understood and are complex, because the specific effects depend on the timing, amount, and duration of exposure as well as genetic susceptibility. Accumulating evidence from studies on DNA methylation and histone modification that affect chromatin structure, as well as on the role of microRNAs in regulating mRNA levels supports the contribution of epigenetic mechanisms to the development of FASD. These epigenetic effects are difficult to study, however, because they often are cell-type specific and transient in nature. Rodent models play an important role in FASD research. Although recent studies using these models have yielded some insight into epigenetic mechanisms affecting brain development, they have generated more questions than they have provided definitive answers. Researchers are just beginning to explore the intertwined roles of different epigenetic mechanisms in neurogenesis and how this process is affected by exposure to alcohol, causing FASD. PMID:24313163

To examine in the Navajo population: (1) the importance of childhood abuse as a risk factor for conduct disorder; (2) the importance of each form of abuse and conduct disorder as risk factors for alcohol dependence; and (3) the relative importance of each form of abuse, conduct disorder, and alcohol dependence as risk factors for being a perpetrator and/or victim of domestic violence. The study is based on a case-control design. Cases (204 men and 148 women) between the ages of 21 and 65 were interviewed in alcohol treatment program and matched to community controls. There were two groups of controls: alcohol dependent (374 men, 60 women) and nonalcohol dependent (157 men, 143 women). When adjusted for stratification by age, community of residence, and sex, the combined control groups comprise a representative sample of the Navajo male and female population 21-65 years of age. The prevalence of physical and sexual abuse before age 15 is within limits observed in other populations. Each form of abuse is a risk factor for conduct disorder. Along with conduct disorder, physical abuse is a risk factor for alcohol dependence. Physical abuse and alcohol dependence are independent risk factors for being involved in domestic violence as both perpetrator and victim. There appears to have been no secular trend in the incidence of childhood abuse over the past several generations, but there is suggestive evidence that domestic violence has become more common. Physical abuse is a significant risk factor for alcohol dependence as well as for domestic violence independent of the effects of alcohol abuse. The effects of sexual abuse with regard to both domestic violence and alcohol dependence do not appear to be significant.

In detoxified alcohol-dependent patients, alcohol-related stimuli can promote relapse. However, to date, the mechanisms by which contextual stimuli promote relapse have not been elucidated in detail. One hypothesis is that such contextual stimuli directly stimulate the motivation to drink via associated brain regions like the ventral striatum and thus promote alcohol seeking, intake and relapse. Pavlovian-to-Instrumental-Transfer (PIT) may be one of those behavioral phenomena contributing to relapse, capturing how Pavlovian conditioned (contextual) cues determine instrumental behavior (e.g. alcohol seeking and intake). We used a PIT paradigm during functional magnetic resonance imaging to examine the effects of classically conditioned Pavlovian stimuli on instrumental choices in n = 31 detoxified patients diagnosed with alcohol dependence and n = 24 healthy controls matched for age and gender. Patients were followed up over a period of 3 months. We observed that (1) there was a significant behavioral PIT effect for all participants, which was significantly more pronounced in alcohol-dependent patients; (2) PIT was significantly associated with blood oxygen level-dependent (BOLD) signals in the nucleus accumbens (NAcc) in subsequent relapsers only; and (3) PIT-related NAcc activation was associated with, and predictive of, critical outcomes (amount of alcohol intake and relapse during a 3 months follow-up period) in alcohol-dependent patients. These observations show for the first time that PIT-related BOLD signals, as a measure of the influence of Pavlovian cues on instrumental behavior, predict alcohol intake and relapse in alcohol dependence. © 2015 Society for the Study of Addiction.

Relapse is common in alcohol-dependent individuals and can be triggered by alcohol-related cues in the environment. It has been suggested that these individuals develop cognitive biases, in which cues automatically capture attention and elicit an approach action tendency that promotes alcohol seeking. The study aim was to examine whether cognitive bias modification (CBM) training targeting approach bias could be delivered during residential alcohol detoxification and improve treatment outcomes. Using a 2-group parallel-block (ratio 1:1) randomized controlled trial with allocation concealed to the outcome assessor, 83 alcohol-dependent inpatients received either 4 sessions of CBM training where participants were implicitly trained to make avoidance movements in response to pictures of alcoholic beverages and approach movements in response to pictures of nonalcoholic beverages, or 4 sessions of sham training (controls) delivered over 4 consecutive days during the 7-day detoxification program. The primary outcome measure was continuous abstinence at 2 weeks postdischarge. Secondary outcomes included time to relapse, frequency and quantity of alcohol consumption, and craving. Outcomes were assessed in a telephonic follow-up interview. Seventy-one (85%) participants were successfully followed up, of whom 61 completed all 4 training sessions. With an intention-to-treat approach, there was a trend for higher abstinence rates in the CBM group relative to controls (69 vs. 47%, p = 0.07); however, a per-protocol analysis revealed significantly higher abstinence rates among participants completing 4 sessions of CBM relative to controls (75 vs. 45%, p = 0.02). Craving score, time to relapse, mean drinking days, and mean standard drinks per drinking day did not differ significantly between the groups. This is the first trial demonstrating the feasibility of CBM delivered during alcohol detoxification and supports earlier research suggesting it may be a useful, low-cost adjunctive treatment to improve treatment outcomes for alcohol-dependent patients.

This article reviews the results of studies concerning particular classes of biological phenotypes that may have relevance for alcohol dependence. Broadly defined, these classes include brain neurotransmitter systems and neuroelectric potentials. Evidence is presented concerning genotypic variation in alcoholics and high-risk relatives suggesting that the etiology of alcoholism and other addictive diseases is mediated in part through suboptimal neurotransmitter functioning. Research opportunities are offered with respect to specific candidate genes that have been cloned from these neurotransmitter systems that could be most fully utilized in family-based genetic analyses. Additional evidence is offered, suggesting that characteristics of particular neuroelectric potentials (e.g. the amplitude of the P300 component of the event-related potential) may provide another dimension of potential markers that could be used to identify children at risk. Finally, methodological considerations specific to high risk studies are discussed. Among these are the need to include a plan for studying more severe cases of alcohol dependence that are relatively uncomplicated by other major psychiatric disorders. Plans for long-term follow-up of children at highest risk for developing the disorder should also be included. Multiple domains of inquiry should not be viewed as "unfocused" but rather as an economical means for utilizing highly characterized samples of individuals meeting rigorous research criteria.

The nucleus accumbens (NAc) is a central component of the mesocorticolimbic reward system. Increasing evidence strongly implicates long-term synaptic neuroadaptations in glutamatergic excitatory activity of the NAc shell and/or core medium spiny neurons in response to chronic drug and alcohol exposure. Such neuroadaptations likely play a critical role in the development and expression of drug-seeking behaviors. We have observed unique cell-type-specific bidirectional changes in NAc synaptic plasticity (metaplasticity) following acute and chronic intermittent ethanol exposure. Other investigators have also previously observed similar metaplasticity in the NAc following exposure to psychostimulants, opiates, and amazingly, even following an anhedonia-inducing experience. Considering that the proteome of the postsynaptic density likely contains hundreds of biochemicals, proteins and other components and regulators, we believe that there is a large number of potential molecular sites through which accumbal metaplasticity may be involved in chronic alcohol abuse. Many of our companion laboratories are now engaged in identifying and screening medications targeting candidate genes and its products previously linked to maladaptive alcohol phenotypes. We hypothesize that if manipulation of such target genes and their products change NAc plasticity, then that observation constitutes an important validation step for the development of novel therapeutics to treat alcohol dependence. © 2016 Elsevier Inc.

Worldwide, alcohol is the second most-used psychotropic substance and the third risk factor for early death and disability. Its noxious use is a world public health problem given its personal, labor, family, economic and social impact. 70 % of people under risk of having alcohol problems go undetected in medical practice, a fact that underlines the need for specific screening measures allowing early detection leading to timely treatment. This article presents evidence gathered by alcohol abuse and dependence screening as well as by risk factor identification and screening. It also presents evidence concerning withdrawal symptoms, delirium tremens and Wernicke's encephalopathy in order to promote early detection and timely treatment. Systematic revision of the evidence available together with an evaluation of pertinent guidelines found in literature so as to decide whether to adopt or adapt the existing recommendation for each question or to develop de novo recommendations. For de novo recommendations as well as those adapted, it was carried out an evidence synthesis, together with evidence tables and formulation of recommendations based on the evidence. Evidence was found and recommendations were made for the pertinent screening and search of risk factors, in order to perform a diagnosis and carry out a timely management of alcohol abuse, dependence and ensuing complications: withdrawal syndrome, delirium tremens and Wernicke's encephalopathy.

Paternal alcoholism and offspring conduct disorder: evidence for the 'common genes' hypothesis.
Haber, Jon R; Jacob, Theodore; Heath, Andrew C
2005-04-01
Not only are alcoholism and externalizing disorders frequently comorbid, they often co-occur in families across generations; for example, paternal alcoholism predicts offspring conduct disorder just as it does offspring alcoholism. To clarify this relationship, the current study examined the 'common genes' hypothesis utilizing a children-of-twins research design. Participants were male monozygotic (MZ) and dizygotic (DZ) twins from the Vietnam Era Twin Registry who were concordant or discordant for alcohol dependence together with their offspring and the mothers of those offspring. All participants were conducted through a structured psychiatric interview. Offspring risk of conduct disorder was examined as a function of alcoholism genetic risk (due to paternal and co-twin alcohol dependence) and alcoholism environmental risk (due to being reared by a father with an alcohol dependence diagnosis). After controlling for potentially confounding variables, the offspring of alcohol-dependent fathers were significantly more likely to exhibit conduct disorder diagnoses than were offspring of nonalcohol-dependent fathers, thus indicating diagnostic crossover in generational family transmission. Comparing offspring at high genetic and high environmental risk with offspring at high genetic and low environmental risk indicated that genetic factors were most likely responsible for the alcoholism-conduct disorder association. The observed diagnostic crossover (from paternal alcoholism to offspring conduct disorder) across generations in the context of both high and low environmental risk (while genetic risk remained high) supported the common genes hypothesis.
Korsakoff minus Wernicke syndrome.
Blansjaar, B A; Van Dijk, J G
1992-07-01
It is commonly believed that Korsakoff's amnesic state in alcoholics is characteristically the sequel to Wernicke's disease. However, in a study of 44 Korsakoff patients it was found that 33 had developed serious memory impairment without having had alarming neurological symptoms. This insidious nature of the onset of the disease indicates that all alcohol-dependent patients should be treated with vitamin B.

Alcohol dependence causes multiple problems not only for the person suffering dependence but also for others. In this study, the contingent valuation method is proposed to measure the intangible effects of alcohol dependence from the perspective of the persons directly involved: the patients and their relatives. Interviews were conducted with 145 patients and 61 relatives. Intangible effects of alcohol dependence were determined based on willingness to pay for a hypothetical treatment for dependence, with different success scenarios (100% and 50%). The mean monthly willingness to pay among the alcohol-dependent population was €129 and €168, respectively, for the treatments with 100% and 50% success. The willingness to pay of relatives was greater in both scenarios (€307 and €420, respectively), which could be explained by their greater perception of the family, labour, and health problems resulting from alcohol dependence. Regression analysis showed that patients' willingness to pay is positively related to treatment efficacy, personal income and moderate health deterioration, and negatively related to feeling discouraged and depressed. The results from this study can be applied to economic valuation studies that aim to measure the benefits of programs intended to reduce the prevalence of alcohol dependence. The intangible costs estimated can be added to the direct and indirect costs commonly used.
Molecular basis of alcoholism.
Most, Dana; Ferguson, Laura; Harris, R Adron
2014-01-01
Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy. © 2014 Elsevier B.V.

Caffeinated Alcoholic Beverages – An Emerging Trend in Alcohol Abuse
Franklin, Kelle M; Hauser, Sheketha R; Bell, Richard L.; Engleman, Eric A
2014-01-01
Alcohol use disorders are pervasive in society and their impact affects quality of life, morbidity and mortality, as well as individual productivity. Alcohol has detrimental effects on an individual’s physiology and nervous system, and is associated with disorders of many organ and endocrine systems impacting an individual’s health, behavior, and ability to interact with others. Youth are particularly affected. Unfortunately, adolescent usage also increases the probability for a progression to dependence. Several areas of research indicate that the deleterious effects of alcohol abuse may be exacerbated by mixing caffeine with alcohol. Some behavioral evidence suggests that caffeine increases alcohol drinking and binge drinking episodes, which in turn can foster the development of alcohol dependence. As a relatively new public health concern, the epidemiological focus has been to establish a need for investigating the effects of caffeinated alcohol. While the trend of co-consuming these substances is growing, knowledge of the central mechanisms associated with caffeinated ethanol has been lacking. Research suggests that caffeine and ethanol can have additive or synergistic pharmacological actions and neuroadaptations, with the adenosine and dopamine systems in particular implicated. However, the limited literature on the central effects of caffeinated ethanol provides an impetus to increase our knowledge of the neuroadaptive effects of this combination and their impact on cognition and behavior. Research from our laboratories indicates that an established rodent animal model of alcoholism can be extended to investigate the acute and chronic effects of caffeinated ethanol. PMID:25419478

Alcohol dependence is characterized by conflict between approach and avoidance motivational orientations for alcohol that operate in automatic and controlled processes. This article describes the first study to investigate the predictive validity of these motivational orientations for relapse to drinking after discharge from alcohol detoxification treatment in alcohol-dependent patients. One hundred twenty alcohol-dependent patients who were nearing the end of inpatient detoxification treatment completed measures of self-reported (Approach and Avoidance of Alcohol Questionnaire; AAAQ) and automatic (modified Stimulus-Response Compatibility task) approach and avoidance motivational orientations for alcohol. Their drinking behavior was assessed via telephone follow-ups at 2, 4, and 6 months after discharge from treatment. Results indicated that, after controlling for the severity of alcohol dependence, strong automatic avoidance tendencies for alcohol cues were predictive of higher percentage of heavy drinking days (PHDD) at 4-month (β = 0.22, 95% CI [0.07, 0.43]) and 6-month (β = 0.22, 95% CI [0.01, 0.42]) follow-ups. We failed to replicate previous demonstrations of the predictive validity of approach subscales of the AAAQ for relapse to drinking, and there were no significant predictors of PHDD at 2-month follow-up. In conclusion, strong automatic avoidance tendencies predicted relapse to drinking after inpatient detoxification treatment, but automatic approach tendencies and self-reported approach and avoidance tendencies were not predictive in this study. Our results extend previous findings and help to resolve ambiguities with earlier studies that investigated the roles of automatic and controlled cognitive processes in recovery from alcohol dependence.

Is it time to ban alcohol advertising?
Anderson, Peter
2009-04-01
Children and adolescents are particularly vulnerable to the harmful effects of alcohol, with heavy drinking risking impaired brain development and future alcohol dependence. Advertisements increase expectancies about alcohol, leading to a greater likelihood of drinking. A systematic review of 13 longitudinal studies of over 38,000 young people found convincing evidence of an impact of media exposure and alcohol advertising on subsequent alcohol use, including initiation of drinking and heavier drinking among existing drinkers. All European countries, with the exception of the UK, have a ban on one or more types of advertising. Since self-regulation is reported as failing to prevent marketing which has an impact on younger people, and since advertising commonly crosses country borders, there is an argument to approximate advertising rules across Europe banning alcohol advertising targeted at young people, a highly cost-effective measure to reduce harmful alcohol use, and one supported by European citizens and case law.

According to prevailing neurobiological theories of addiction, altered function in neural reward circuitry is a central mechanism of alcohol dependence. Growing evidence postulates that the ventral striatum (VS), as well as areas of the prefrontal cortex, contribute to the increased incentive salience of alcohol-associated cues, diminished motivation to pursue non-drug rewards and weakened strength of inhibitory cognitive control, which are central to addiction. The present study aims to investigate the neural response and functional connectivity underlying monetary, non-drug reward processing in alcohol dependence. We utilized a reward paradigm to investigate the anticipation of monetary reward in 32 alcohol-dependent inpatients and 35 healthy controls. Functional magnetic resonance imaging was used to measure task-related brain activation and connectivity. Alcohol-dependent patients showed increased activation of the VS during anticipation of monetary gain compared with healthy controls. Generalized psychophysiological interaction analyses revealed decreased functional connectivity between the VS and the dorsolateral prefrontal cortex in alcohol dependent patients relative to controls. Increased activation of the VS and reduced frontostriatal connectivity were associated with increased craving. These findings provide evidence that alcohol dependence is rather associated with disrupted integration of striatal and prefrontal processes than with a global reward anticipation deficit. © 2016 Society for the Study of Addiction.
The epigenetic landscape of alcoholism.
Krishnan, Harish R; Sakharkar, Amul J; Teppen, Tara L; Berkel, Tiffani D M; Pandey, Subhash C

Alcoholism is a complex psychiatric disorder that has a multifactorial etiology. Epigenetic mechanisms are uniquely capable of accounting for the multifactorial nature of the disease in that they are highly stable and are affected by environmental factors, including alcohol itself. Chromatin remodeling causes changes in gene expression in specific brain regions contributing to the endophenotypes of alcoholism such as tolerance and dependence. The epigenetic mechanisms that regulate changes in gene expression observed in addictive behaviors respond not only to alcohol exposure but also to comorbid psychopathology such as the presence of anxiety and stress. This review summarizes recent developments in epigenetic research that may play a role in alcoholism. We propose that pharmacologically manipulating epigenetic targets, as demonstrated in various preclinical models, hold great therapeutic potential in the treatment and prevention of alcoholism. © 2014 Elsevier Inc.

Individuals in recovery from alcohol use disorders (AUDs) frequently continue to smoke cigarettes. The purpose of this study was to examine the relationship between cigarette smoking status and risk of AUD relapse in adults with remitted AUDs among adults in the United States. Data were drawn from Wave 1 (2001 to 2002) and Wave 2 (2004 to 2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Analyses included the subsample of respondents who completed both waves of data collection reported a history of alcohol abuse and/or dependence prior to Wave 1 (N = 9,134). Relationships between Wave 1 cigarette smoking status (nonsmoker, daily cigarette smoker, and nondaily cigarette smoker) and Wave 2 alcohol use, abuse, and dependence were examined using logistic regression analyses. Analyses were adjusted for Wave 1 demographics; mood, anxiety, and substance use disorders; nicotine dependence; and AUD severity. Both daily and nondaily cigarette smoking at Wave 1 were significantly associated with a lower likelihood of alcohol use and a greater likelihood of alcohol abuse and dependence at Wave 2 compared to Wave 1 nonsmoking. These relationships remained significant after adjusting for demographics, psychiatric disorders, substance use disorders, AUD severity, and nicotine dependence. Among adults with remitted AUDs, daily and nondaily use of cigarettes was associated with significantly decreased likelihood of alcohol use and increased likelihood of alcohol abuse and alcohol dependence 3 years later. Concurrent treatment of cigarette smoking when treating AUDs may help improve long-term alcohol outcomes and reduce the negative consequences of both substances.

This study tested the hypothesis that abnormalities in components of the serotonin (5HT) system in the prefrontal cortex are associated with suicide in alcohol-dependent subjects. Second, we assessed the relationship of lifetime impulsivity and mood symptoms with prefrontal cortex 5-HT measures. Tissue was obtained from Brodmann's areas (BA) 9 and 24 in postmortem samples of individuals who were alcohol dependent with suicide (n = 5), alcohol dependent without suicide (n = 9) and normal controls (n = 5). Serotonin receptor (5HT) and serotonin reuptake transporter (SERT) mRNA were measured. Interviews with next of kin estimated lifetime impulsivity and mood symptoms in the last week of life. Serotonin receptor 1A (5HT1A) mRNA in BA 9 was elevated in the alcohol dependence without suicide group compared with controls. In the alcohol dependence with suicide group, anxiety symptoms were associated with decreased BA 24 SERT mRNA and depressive symptoms with BA 9 5HT1A mRNA expression. In the alcohol dependent only group impulsivity is correlated with increased BA 9, and BA 24 serotonin receptor 2A mRNA. Our data suggest region-specific change, rather than global serotonin blunting is involved in alcohol dependence and suicide. It also suggests that symptoms are differentially influenced by prefrontal cortex serotonin receptor mRNA levels. © 2011 John Wiley & Sons A/S.

To explore the association between male adult alcohol dependence and their adverse childhood experiences as well as ecological executive function. The questionnaires of Adverse Childhood Experiences (ACEs) and Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) were adopted for the assessments of 102 alcohol dependent patients who were diagnosed according to the criteria defined by the International Classification of diseases and related health problems (ICD-10) and 106 healthy volunteers, and the differences between patients and healthy volunteers were analyzed. The percentage of adverse childhood experiences in alcohol dependent patients was significantly higher than that in healthy volunteers (χ(2)=17.28, P<0.01); and the incidences of emotional abuse, physical neglect, violence witness, and substance abuse were significantly higher in alcohol dependent patients than those in healthy volunteers (χ(2)=4.59, 4.46, 10.51, and 44.09 respectively; P<0.05). The ecological executive function analysis showed that the BRIEF total score and scores for each item were all significantly higher in alcohol dependent patients than those of healthy volunteers (P<0.01). The adult alcohol dependence was associated with their adverse childhood experiences and ecological executive function. Then physical neglect and substance abuse of parents in childhood, and emotional control defect in the ecological executive function showed strong association with adult alcohol dependence.

Adolescents with attention-deficit/hyperactivity disorder (ADHD) are known to be at significantly greater risk for the development of substance use disorders (SUD) compared to peers. Impulsivity, which could lead to higher levels of drug use, is a known symptom of ADHD and likely accounts, in part, for this relationship. Other factors, such as a biologically increased susceptibility to substance dependence (addiction), may also play a role. This report further examines the relationships between childhood ADHD, adolescent- onset SUD, and substance abuse and substance dependence in adulthood. Individuals with childhood ADHD and non-ADHD controls from the same population-based birth cohort were invited to participate in a prospective outcome study. Participants completed a structured neuropsychiatric interview with modules for SUD and a psychosocial questionnaire. Information on adolescent SUD was obtained retrospectively, in a previous study, from medical and school records. Associations were summarized using odds ratios (OR) and 95% CIs estimated from logistic regression models adjusted for age and gender. A total of 232 ADHD cases and 335 non-ADHD controls participated (mean age, 27.0 and 28.6 years, respectively). ADHD cases were more likely than controls to have a SUD diagnosed in adolescence and were more likely to have alcohol (adjusted OR 14.38, 95% CI 1.49-138.88) and drug (adjusted OR 3.48, 95% CI 1.38-8.79) dependence in adulthood. The subgroup of participating ADHD cases who did not have SUD during adolescence were no more likely than controls to develop new onset alcohol dependence as adults, although they were significantly more likely to develop new onset drug dependence. Our study found preliminary evidence that adults with childhood ADHD are more susceptible than peers to developing drug dependence, a disorder associated with neurological changes in the brain. The relationship between ADHD and alcohol dependence appears to be more complex.

Adolescent Alcohol Exposure Persistently Impacts Adult Neurobiology and Behavior
Vetreno, Ryan P.; Broadwater, Margaret A.; Robinson, Donita L.
2016-01-01
Adolescence is a developmental period when physical and cognitive abilities are optimized, when social skills are consolidated, and when sexuality, adolescent behaviors, and frontal cortical functions mature to adult levels. Adolescents also have unique responses to alcohol compared with adults, being less sensitive to ethanol sedative–motor responses that most likely contribute to binge drinking and blackouts. Population studies find that an early age of drinking onset correlates with increased lifetime risks for the development of alcohol dependence, violence, and injuries. Brain synapses, myelination, and neural circuits mature in adolescence to adult levels in parallel with increased reflection on the consequence of actions and reduced impulsivity and thrill seeking. Alcohol binge drinking could alter human development, but variations in genetics, peer groups, family structure, early life experiences, and the emergence of psychopathology in humans confound studies. As adolescence is common to mammalian species, preclinical models of binge drinking provide insight into the direct impact of alcohol on adolescent development. This review relates human findings to basic science studies, particularly the preclinical studies of the Neurobiology of Adolescent Drinking in Adulthood (NADIA) Consortium. These studies focus on persistent adult changes in neurobiology and behavior following adolescent intermittent ethanol (AIE), a model of underage drinking. NADIA studies and others find that AIE results in the following: increases in adult alcohol drinking, disinhibition, and social anxiety; altered adult synapses, cognition, and sleep; reduced adult neurogenesis, cholinergic, and serotonergic neurons; and increased neuroimmune gene expression and epigenetic modifiers of gene expression. Many of these effects are specific to adolescents and not found in parallel adult studies. AIE can cause a persistence of adolescent-like synaptic physiology, behavior, and sensitivity to alcohol into adulthood. Together, these findings support the hypothesis that adolescent binge drinking leads to long-lasting changes in the adult brain that increase risks of adult psychopathology, particularly for alcohol dependence.

Mexican Americans comprise one of the most rapidly growing populations in the United States, and within this population, trauma and post-traumatic stress disorder (PTSD) are associated with physical and mental health problems. Therefore, efforts to delineate factors that may uniquely contribute to increased likelihood of trauma, PTSD, and substance use disorders over the lifetime in Mexican Americans are important to address health disparities and to develop treatment and prevention programs. Six hundred fourteen young adults (age 18–30 yrs) of Mexican American heritage, largely second generation, were recruited from the community and assessed with the Semi-Structured Assessment for the Genetics of Alcoholism and an acculturation stress scale. More males (51.2%) reported experiencing traumas than females (41.1%), however, a larger proportion of females received a PTSD diagnosis (15%) than males (8%). Alcohol dependence and affective disorders, but not anxiety disorders, antisocial disorders, nicotine, marijuana, or stimulant dependence, were significantly comorbid with PTSD. Endorsing higher levels of acculturation stress was also significantly associated with both trauma exposure and a diagnosis of PTSD. Logistic regression revealed that female gender, having an affective disorder, alcohol dependence, higher levels of acculturation stress, and lower levels of education were all predictors of PTSD status. Additionally, alcohol dependence generally occurred after the PTSD diagnosis in early adulthood in this high-risk population. These studies suggest that treatment and prevention efforts should particularly focus on young adult second generation Mexican American women with higher levels of acculturation stress, who may be at higher risk for PTSD, affective disorder, and alcohol dependence following trauma exposure.

Obsessive-compulsive aspects of craving: development of the Obsessive Compulsive Drinking Scale.
Anton, R F
2000-08-01
"Craving" for alcohol needs improved definition and measurement. This review provides a rationale for considering at least certain aspects of craving as having obsessive and compulsive features. As such, there may be phenomenological, but not necessarily etiological, overlap with obsessive-compulsive disorder. There are increasing data that suggest a neuroanatomical overlap between addiction/craving and obsessive-compulsive symptoms. The self-rated Obsessive Compulsive Drinking Scale (OCDS), based on the Yale-Brown Obsessive Compulsive Scale for heavy drinking interview (YBOCS-hd), was developed to assist in the examination of certain aspects of "craving" in alcoholics. The development, reliability, face validity, congruent validity and predictive validity of the OCDS are presented and discussed in this paper. The utility of the OCDS as a measurement tool in cognitive-behavioral and pharmacological alcoholism treatment research is highlighted. The potential of this instrument as a research and clinical tool for the understanding and evaluation of alcohol dependence needs further evaluation.

The frequency ADH2-2 allele in the Moscow urban population and a correlation between the ADH2-2 allele, alcoholic dependence without cirrhosis, symptomatic alcoholic cirrhosis and status on hepatitis B and C infection have been studied. One hundred and twenty-three inhabitants of Moscow (50 healthy donors, 36 patients with alcoholic cirrhosis (subdivided into infected and uninfected by HBV and/or HCV) and 37 patients with alcoholic dependence) of a similar age/sex and drinking pattern have been analysed. The frequency of 41% for ADH2-2 allele is characteristic for an urban Moscow population. This value is intermediate between that found for Asian peoples and for Central and Western Europe. There is a negative correlation between the ADH2-2 allele and alcohol misuse (both alcoholic dependence and alcoholic cirrhosis). This correlation is expressed more in alcoholic dependence. In spite of the possession of the ADH2-2 allele (or genotype ADH2-1/2), alcohol misuse increases the risk of cirrhosis. At the same time, positive status for active hepatitis B, C or combined infection B + C (replication markers HBV-DNA or HCV-RNA) increases the risk for symptomatic alcoholic cirrhosis in alcohol abusing patients, independently of ADH2 genotype.
The Role of GABAA Receptors in the Development of Alcoholism
Enoch, Mary-Anne
2008-01-01
Alcoholism is a common, heritable, chronic relapsing disorder. GABAA receptors undergo allosteric modulation by ethanol, anesthetics, benzodiazepines and neurosteroids and have been implicated in the acute as well as the chronic effects of ethanol including tolerance, dependence and withdrawal. Medications targeting GABAA receptors ameliorate the symptoms of acute withdrawal. Ethanol induces plasticity in GABAA receptors: tolerance is associated with generally decreased GABAA receptor activation and differentially altered subunit expression. The dopamine (DA) mesolimbic reward pathway originating in the ventral tegmental area (VTA), and interacting stress circuitry play an important role in the development of addiction. VTA GABAergic interneurons are the primary inhibitory regulators of DA neurons and a subset of VTA GABAA receptors may be implicated in the switch from heavy drinking to dependence. GABAA receptors modulate anxiety and response to stress; important elements of sustained drinking and relapse. The GABAA receptor subunit genes clustered on chromosome 4 are highly expressed in the reward pathway. Several recent studies have provided strong evidence that one of these genes, GABRA2, is implicated in alcoholism in humans. The influence of the interaction between ethanol and GABAA receptors in the reward pathway on the development of alcoholism together with genetic and epigenetic vulnerabilities will be explored in this review.

Dynorphins are critically involved in the development, maintenance and relapse of alcoholism. Alcohol-induced changes in the prodynorphin gene expression may be influenced by both gene polymorphisms and epigenetic modifications. The present study of human alcoholics aims to evaluate DNA methylation patterns in the prodynorphin gene (PDYN) promoter and to identify single nucleotide polymorphisms (SNPs) associated with alcohol dependence and with altered DNA methylation. Genomic DNA was isolated from peripheral blood cells of alcoholics and healthy controls, and DNA methylation was studied in the PDYN promoter by bisulfite pyrosequencing. In alcoholics, DNA methylation increased in three of the seven CpG sites investigated, as well as in the average of the seven CpG sites. Data stratification showed lower increase in DNA methylation levels in individuals reporting craving and with higher levels of alcohol consumption. Association with alcoholism was observed for rs2235751 and the presence of the minor allele G was associated with reduced DNA methylation at PDYN promoter in females and younger subjects. Genetic and epigenetic factors within PDYN are related to risk for alcoholism, providing further evidence of its involvement on ethanol effects. These results might be of relevance for developing new biomarkers to predict disease trajectories and therapeutic outcome. Copyright © 2017 Elsevier Inc. All rights reserved.

The central amygdala is a critical brain region for many aspects of alcohol dependence. Much of the work examining the mechanisms by which the central amygdala mediates the development of alcohol dependence has focused on the interaction of acute and chronic ethanol with central amygdala corticotropin releasing factor signaling. This work has led to a great deal of success in furthering the general understanding of central amygdala neurocircuitry and its role in alcohol dependence. Much of this work has primarily focused on the hypothesis that ethanol utilizes endogenous corticotropin releasing factor signaling to upregulate inhibitory GABAergic transmission in the central amygdala. Work that is more recent suggests that corticotropin releasing factor also plays an important role in mediating anxiety-like behaviors via the enhancement of central amygdala glutamatergic transmission, implying that ethanol/corticotropin releasing factor interactions may modulate excitatory neurotransmission in this brain region. In addition, a number of studies utilizing optogenetic strategies or transgenic mouse lines have begun to examine specific central amygdala neurocircuit dynamics and neuronal subpopulations to better understand overall central amygdala neurocircuitry and the role of neuronal subtypes in mediating anxiety-like behaviors. This review will provide a brief update on this literature and describe some potential future directions that may be important for the development of better treatments for alcohol addiction.

Energy drink consumption and increased risk for alcohol dependence
Arria, Amelia M.; Caldeira, Kimberly M.; Kasperski, Sarah J.; Vincent, Kathryn B.; Griffiths, Roland R.; O'Grady, Kevin E.
2010-01-01
Background Energy drinks are highly caffeinated beverages that are increasingly consumed by young adults. Prior research has established associations between energy drink use and heavier drinking and alcohol-related problems among college students. This study investigated the extent to which energy drink use might pose additional risk for alcohol dependence over and above that from known risk factors. Methods Data were collected via personal interview from 1,097 fourth-year college students sampled from one large public university as part of an ongoing longitudinal study. Alcohol dependence was measured with DSM-IV criteria. Results After adjustment for the sampling design, 51.3%wt of students were classified as “low-frequency” energy drink users (1 to 51 days in the past year) and 10.1%wt as “high-frequency” users (≥52 days). Typical caffeine consumption varied widely depending on the brand consumed. Compared to the low-frequency group, high-frequency users drank alcohol more frequently (141.6 vs. 103.1 days) and in higher quantities (6.15 vs. 4.64 drinks/typical drinking day). High-frequency users were at significantly greater risk for alcohol dependence relative to both non-users (AOR=2.40, 95% CI=1.27-4.56, p=.007) and low-frequency users (AOR=1.86, 95% CI=1.10, 3.14, p=.020), even after holding constant demographics, typical alcohol consumption, fraternity/sorority involvement, depressive symptoms, parental history of alcohol/drug problems, and childhood conduct problems. Low-frequency energy drink users did not differ from non-users on their risk for alcohol dependence. Conclusions Weekly or daily energy drink consumption is strongly associated with alcohol dependence. Further research is warranted to understand the possible mechanisms underlying this association. College students who frequently consume energy drinks represent an important target population for alcohol prevention. PMID:21073486

To evaluate the prevalence of alcohol abuse and/or dependence in a population-based sample of young adults and assess the prevalence of comorbid mood disorders, anxiety, and suicide risk in this population. This cross-sectional, population-based study enrolled 1,953 young adults aged 18-35 years. The CAGE questionnaire was used to screen for alcohol abuse and/or dependence, with CAGE scores ≥ 2 considered positive. Psychiatric disorders were investigated through the structured Mini International Neuropsychiatric Interview (MINI). Alcohol abuse and/or dependence was identified in 187 (9.60%) individuals (5.10% among women and 15.20% among men). Alcohol abuse and/or dependence were more prevalent among men than women, as well as among those who used tobacco, illicit drugs or presented with anxiety disorder, mood disorder, and suicide risk. These findings suggest that alcohol abuse and/or dependence are consistently associated with a higher prevalence of psychiatric comorbidities, could be considered important predictors of other psychiatric disorders, and deserve greater public heath attention, pointing to the need for alcohol abuse prevention programs.

In recent years, we have come to recognize that a multitude of in utero exposures have the capacity to induce the development of congenital and metabolic defects. As most of these encounters manifest their effects beyond the window of exposure, deciphering the mechanisms of teratogenesis is incredibly difficult. For many agents, altered epigenetic programming has become suspect in transmitting the lasting signature of exposure leading to dysgenesis. However, while several chemicals can perturb chromatin structure acutely, for many agents (particularly alcohol) it remains unclear if these modifications represent transient responses to exposure or heritable lesions leading to pathology. Here, we report that mice encountering an acute exposure to alcohol on gestational Day-7 exhibit significant alterations in chromatin structure (histone 3 lysine 9 dimethylation, lysine 9 acetylation, and lysine 27 trimethylation) at Day-17, and that these changes strongly correlate with the development of craniofacial and central nervous system defects. Using a neural cortical stem cell model, we find that the epigenetic changes arising as a consequence of alcohol exposure are heavily dependent on the gene under investigation, the dose of alcohol encountered, and that the signatures arising acutely differ significantly from those observed after a 4-day recovery period. Importantly, the changes observed post-recovery are consistent with those modeled in vivo, and associate with alterations in transcripts encoding multiple homeobox genes directing neurogenesis. Unexpectedly, we do not observe a correlation between alcohol-induced changes in chromatin structure and alterations in transcription. Interestingly, the majority of epigenetic changes observed occur in marks associated with repressive chromatin structure, and we identify correlative disruptions in transcripts encoding Dnmt1, Eed, Ehmt2 (G9a), EzH2, Kdm1a, Kdm4c, Setdb1, Sod3, Tet1 and Uhrf1. These observations suggest that the immediate and long-term impacts of alcohol exposure on chromatin structure are distinct, and hint at the existence of a possible coordinated epigenetic response to ethanol during development. Collectively, our results indicate that alcohol-induced modifications to chromatin structure persist beyond the window of exposure, and likely contribute to the development of fetal alcohol syndrome-associated congenital abnormalities.

Objective. Emotional intelligence might play an important role in the onset and persistence of different psychopathologies. This study investigated the relationship between emotional intelligence and alcohol dependence. Methods. In this case-control study, participants included alcohol dependent individuals and mentally healthy inpatients. Each group consisted of 40 individuals (male/female: 1). The diagnosis was based on the criteria of the DSM-IV-TR using the Structured Clinical Interview for DSM-IV (SCID-IV). All the participants completed Bar-On emotional intelligence test. Results. 20 males and 20 females were included in each group. Mean age of alcohol dependent participants and controls was 31.28 ± 7.82 and 34.93 ± 9.83 years in that order. The analyses showed that the alcohol dependent individuals had a significant difference compared with the control group and received lower scores in empathy, responsibility, impulse control, self-esteem, optimism, emotional consciousness, stress tolerance, autonomy, problem-solving, and total score of emotional intelligence components. Conclusion. Patients with alcohol dependence have deficits in components of emotional intelligence. Identifying and targeted training of the individuals with lower scores in components of emotional intelligence may be effective in prevention of alcohol dependence. PMID:25893214

Alcohol dependence is a severely stigmatized disorder. Perceived stigma may deter help-seeking and is associated with higher co-morbidity and self-stigma in persons with alcohol dependence. We assess changes in the perception of alcohol-related stigma over 21 years in the general population. Two representative population surveys using identical methodology were conducted in Germany in 1990 and 2011 (n=1022 and n=967), eliciting the perceived discrimination and devaluation of someone with a history of alcohol problems as measured with an adoption of Link's Perceived Discrimination and Devaluation Scale (aPDDS), and perceived negative stereotypes of an "alcoholic." Both on item level and using factor scores, attitudes changed significantly between 1990 and 2011. Perceived discrimination and devaluation of someone with a history of alcohol dependence decreased considerably by 0.44 standard deviations (SD). Perceived negative stereotypes related to unpredictability of an "alcoholic" increased slightly by 0.15 SD, while perceived stereotypes related to strangeness decreased (-0.23 SD). Our findings suggest that particularly the image of someone who has received treatment for alcohol dependence has improved in Germany. This parallels increasing acceptance of professional treatment for alcohol dependence among the general population over the last twenty years, and contrasts with overall unchanged negative attitudes toward persons who actually suffer from alcohol problems.

Are the binary typology models of alcoholism valid in polydrug abusers?
Pombo, Samuel; da Costa, Nuno F; Figueira, Maria L

To evaluate the dichotomy of type I/II and type A/B alcoholism typologies in opiate-dependent patients with a comorbid alcohol dependence problem (ODP-AP). The validity assessment process comprised the information regarding the history of alcohol use (internal validity), cognitive-behavioral variables regarding substance use (external validity), and indicators of treatment during 6-month follow-up (predictive validity). ODP-AP subjects classified as type II/B presented an early and much more severe drinking problem and a worse clinical prognosis when considering opiate treatment variables as compared with ODP-AP subjects defined as type I/A. Furthermore, type II/B patients endorse more general positive beliefs and expectancies related to the effect of alcohol and tend to drink heavily across several intra- and interpersonal situations as compared with type I/A patients. These findings confirm two different forms of alcohol dependence, recognized as a low-severity/vulnerability subgroup and a high-severity/vulnerability subgroup, in an opiate-dependent population with a lifetime diagnosis of alcohol dependence.

Increased susceptibility for developing alcohol dependence (AD) may be related to structural and functional differences in brain circuits that influence social cognition and more specifically, theory of mind (ToM). Alcohol dependent individuals have a greater likelihood of having deficits in social skills and greater social alienation. These characteristics may be related to inherited differences in the neuroanatomical network that comprises the social brain. Adolescent/young adult participants from multiplex AD families and controls (n = 16) were matched for gender, age, IQ, education, and handedness and administered the Eyes Task of Baron-Cohen during functional magnetic resonance imaging (fMRI). High-risk (HR) subjects showed significantly diminished blood oxygen level dependent (BOLD) response in comparison with low-risk control young adults in the right middle temporal gyrus (RMTG) and the left inferior frontal gyrus (LIFG), areas that have previously been implicated in ToM tasks. Offspring from multiplex families for AD may manifest one aspect of their genetic susceptibility by having a diminished BOLD response in brain regions associated with performance of ToM tasks. These results suggest that those at risk for developing AD may have reduced ability to empathize with others' state of mind, possibly resulting in diminished social skill.

Using insights from Ecological Systems Theory and Reinforcement Sensitivity Theory, the current study assessed the utility of a series of hypothetical role-based alcohol-consumption scenarios that varied in their presentation of rewarding and punishing information. The scenarios, along with measures of impulsive sensation seeking and a self-report of weekly alcohol consumption, were administered to a sample of alcohol-dependent and non-alcohol-dependent college-age individuals (N = 170). The results showed scenario attendance decisions were largely unaffected by alcohol-dependence status and variations in contextual reward and punishment information. In contrast to the attendance findings, the results for the alcohol-consumption decisions showed alcohol-dependent individuals reported a greater frequency of deciding to drink, as well as indicating greater alcohol consumption in the contexts of complementary rewarding or nonpunishing information. Regression results provided evidence for the criterion-related validity of scenario outcomes in an account of diagnostic alcohol problems. The results are discussed in terms of the conceptual and predictive gains associated with an assessment approach to alcohol-consumption decision making that combines situational information organized and balanced through the frameworks of Ecological Systems Theory and Reinforcement Sensitivity Theory.

To explore the relationship between alcohol abuse/dependence with burnout and other forms of distress among a national cohort of medical students. In 2012, the authors completed a national survey of medical students from the American Medical Association's Physician Masterfile containing validated items assessing alcohol abuse/dependence, burnout, depression, suicidality, quality of life (QOL), and fatigue. Descriptive and comparative statistical analyses were computed, including chi-square and multivariate logistic regression, to determine relationships between variables. Of the 12,500 students, 4,402 (35.2%) responded. Of these, 1,411 (32.4%) met diagnostic criteria for alcohol abuse/dependence. Students who were burned out (P = .01), depressed (P = .01), or reported low mental (P =.03) or emotional (P = .016) QOL were more likely to have alcohol abuse/dependence. Emotional exhaustion and depersonalization domains of burnout were strongly associated with alcohol abuse/dependence. On multivariate analysis, burnout (OR 1.20; 95% CI 1.05-1.37; P < .01), having $50,000 to $100,000 (OR 1.21 versus < $50,000; CI 1.02-1.44; P < .05) or > $100,000 (OR 1.27 versus < $50,000; CI 1.08-1.48; P < .01) of educational debt, being unmarried (OR 1.89; CI 1.57-2.27; P < .001), and being younger (for every five years, OR 1.15; CI 1.02-1.28; P = .01) were independently associated with increased risk for alcohol abuse/dependence. Burnout was strongly related to alcohol abuse/dependence among sampled medical students and increased educational debt predicted a higher risk. A multifaceted approach addressing burnout, medical education costs, and alcohol use is needed.

Little is known about to what extent treatment-seeking behavior varies across individuals with alcohol abuse, alcohol dependence, drug abuse, and drug dependence. The sample included respondents from the Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) who reported a lifetime diagnosis alcohol abuse, alcohol dependence, drug abuse, or drug dependence. Unadjusted and adjusted hazard ratios are presented for time to first treatment contact by sociodemographic characteristics and comorbid psychiatric disorders. Individuals were censored from the analyses if their condition remitted prior to seeking treatment. In the first year after disorder onset, rates of treatment-seeking were 13% for drug dependence, 5% for alcohol dependence, 2% for drug abuse, and 1% for alcohol abuse. The lifetime probability of seeking treatment among individuals who did not remit was also highest for drug dependence (90%), followed by drug abuse (60%), alcohol dependence (54%), and alcohol abuse (16%). Having had previous treatment contact for a substance use disorder (SUD) increased the probability of seeking treatment for another SUD. By contrast, an early age of SUD onset, belonging to an older cohort, and a higher level of education decreased the lifetime probability of treatment contact for SUD. The role of comorbid mental disorders was more complex, with some disorders increasing and other decreasing the probability of seeking treatment. Given high rates of SUD and their substantial health and economic burden, these patterns suggest the need for innovative approaches to increase treatment access for individuals with SUD.

To examine the genetic and environmental influences of parental alcoholism on offspring disinhibited behavior. We compared the effect of parental alcoholism history on offspring in adoptive and non-adoptive families. In families with a history of parental alcohol dependence, we examined the effect of exposure to parental alcoholism symptoms during the life-time of the adolescent. Setting Assessments occurred at the University of Minnesota from 1998 to 2004. Adolescents adopted in infancy were ascertained systematically from records of three private Minnesota adoption agencies; non-adopted adolescents were ascertained from Minnesota birth records. Adolescents and their rearing parents participated in in-person assessments. For adolescents, measures included self- reports of delinquency, deviant peers, substance use, antisocial attitudes and personality. For parents, we conducted DSM-IV clinical assessments of alcohol abuse and dependence. A history of parental alcohol dependence was associated with higher levels of disinhibition only when adolescents were related biologically to their rearing parents. Within families with a history of parental alcoholism, exposure to parental alcohol misuse during the life-time of the adolescent was associated with increased odds of using alcohol in adopted adolescents only. These findings suggest that the association between a history of parental alcohol dependence and adolescent offspring behavioral disinhibition is attributable largely to genetic rather than environmental transmission. We also obtained some evidence for parental alcohol misuse as a shared environmental risk factor in adoptive families.

The aim of the present study was to evaluate the prevalence of lifetime posttraumatic stress disorder (PTSD) in Turkish male alcohol-dependent inpatients, and to investigate the relationship of lifetime PTSD diagnosis with anxiety, depression, hopelessness, erectile dysfunction and psychosocial problems related with alcohol dependency. Eighty-two male inpatients who met DSM-IV criteria for alcohol dependence and 48 subjects without substance use disorder as a control group were included in the study. Subjects were applied the Hamilton Depression Rating Scale (HAM-D), the Hamilton Anxiety Rating Scale (HAM-A), the Michigan Alcoholism Screening Test (MAST), the Beck Hopelessness Scale (BHS) and the International Index of Erectile Function (IIEF). Rate of lifetime PTSD diagnosis was found to be 26.8% among alcohol-dependent inpatients. The mean age of patients with lifetime PTSD was lower than in patients without this diagnosis, while there were no significant differences between these two groups in terms of age of first alcohol use, lifetime major depression, current depression, presence and severity of erectile dysfunction. Mean scores of HAM-D, HAM-A, BHS and MAST in the group with lifetime PTSD were significantly higher than the group without this diagnosis. There was a positive relationship between lifetime PTSD diagnosis and depression, anxiety, hopelessness and severity of psychosocial problems related to alcohol dependency, while there was no relationship between lifetime PTSD comorbidity and erectile dysfunction in alcohol-dependent patients.

Objective Little research has been done on alcohol use and dependence among rural residents in China, a sub-population that might be under increased stress due to the rapid modernization and urbanization processes. We aimed to assess rural residents’ levels of stress, negative emotions, resilience, alcohol use/dependence and the complex relationships among them. Methods Survey data from a large random sample (n = 1145, mean age = 35.9, SD = 7.7, 50.7% male) of rural residents in Wuhan, China were collected using Audio Computer-Assisted Self-Interview. Results The sample had high prevalence of frequently perceived stress (47%) and high prevalence of ever (54.4%), past 30-day (40.4%), and binge drinking (13.8%). Approximately 11% met the criterion for intermediate to severe alcohol dependence. Mediation analysis indicated that the association between perceived stress (predictor) and alcohol dependence (outcome) was fully mediated by anxiety (indirect effect = .203, p < .01) and depression (indict effect =.158, p < .05); moderation analysis indicated that association between stress and two negative emotions (mediators) was significantly modified by resilience (moderator); an integrative moderated mediation analysis indicated that the indirect effect from stress to alcohol dependence through negative emotions was also moderated by resilience. Conclusions Negative emotions play a key role in bridging stress and alcohol dependence, while resilience significantly buffers the impact of stress on depression, reducing the risk of alcohol dependence. Resilience training may be an effective component for alcohol intervention in rural China. PMID:26342628

Most screening questionnaires are developed in clinical settings and there are few data on their performance in the general population. This study provides data on the area under the receiver-operating characteristic (ROC) curve, sensitivity, specificity, and internal consistency of the Alcohol Use Disorders Identification Test (AUDIT), the consumption questions of the AUDIT (AUDIT-C) and the Lübeck Alcohol Dependence and Abuse Screening Test (LAST) among current drinkers (n = 3551) of a general population sample in northern Germany. Alcohol dependence and misuse according to DSM-IV and at-risk drinking served as gold standards to assess sensitivity and specificity and were assessed with the Munich-Composite Diagnostic Interview (M-CIDI). AUDIT and LAST showed insufficient sensitivity for at-risk drinking and alcohol misuse using standard cut-off scores, but satisfactory detection rates for alcohol dependence. The AUDIT-C showed low specificity in all criterion groups with standard cut-off. Adjusted cut-points are recommended. Among a subsample of individuals with previous general hospital admission in the last year, all questionnaires showed higher internal consistency suggesting lower reliability in non-clinical samples. In logistic regression analyses, having had a hospital admission increased the sensitivity in detecting any criterion group of the LAST, and the number of recent general practice visits increased the sensitivity of the AUDIT in detecting alcohol misuse. Women showed lower scores and larger areas under the ROC curves. It is concluded that setting specific instruments (e.g. primary care or general population) or adjusted cut-offs should be used.

The aim of this study was to determine the effects of life-time tobacco, alcohol, and substance use on psychological and behavioral variables among 10th grade students in Istanbul/Turkey. This study employed a cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul. The questionnaire featured a section about use of substances, including tobacco, alcohol, and drugs. The depression, anxiety, anger, assertiveness, sensation seeking and impulsiveness subscales of the Psychological Screening Test for Adolescents (PSTA) were used. The analyses were conducted based on 4957 subjects. Logistic regression analyses were conducted with each school with the related and behavioral variables as the dependent variables. Gender, tobacco, alcohol, and drug use being the independent variables. All four independent variables predicted the dependent variables. Lifetime tobacco and drug use had significant effects on all the subscale score, whereas lifetime alcohol use had significant effects on all the subscale scores other than lack of assertiveness, and male gender was a significant covariant for all the subscale scores. Drug use showed the highest effect on dependent variables. Interaction was found between effects of tobacco and alcohol on anxiety, whereas interactions were found between effects of tobacco and drugs on lack of assertiveness and impulsiveness. The findings suggested that male students with lifetime tobacco, alcohol or drug use have particularly high risk of psychological and behavioral problems. The unique effects of substance clusters on these problems may be useful in developing secondary preventive practices for substance use and abuse problems in Istanbul.

Neuropsychological impairments of the executive functions, memory, attention, intelligence quotient, and empathy have been found in perpetrators of domestic violence (intimate partner violence). These impairments could be partially explained by alcohol abuse, dependence, or traumatic brain injuries. This study reviews the neuropsychological deficits of perpetrators of intimate partner violence. At the same it seeks to integrate and relate these main points with their neuroanatomical correlates. We have also established the relationship between alcohol abuse, dependence, brain damage (including traumatic brain injuries) and those deficits. Scientific literature has been reviewed by means of Google Scholar, PsycINFO, PubMed, Medline and ISI Web of Knowledge. Perpetrators of domestic violence present high mental rigidity, as well as low levels of inhibition, processing speed, verbal and attention skills, and abstract reasoning. Additionally, perpetrators show working and long play memory impairments. Moreover, those deficits could be impaired by traumatic brain injuries and alcohol abuse and/or dependence. Nonetheless, these both variables are not enough to explain the deficits. Functional abnormalities on the prefrontal and occipital cortex, fusiform gyrus, posterior cingulate gyrus, hippocampus, thalamus and amygdala could be associated with these impairments. An analysis of these mechanisms may assist in the development of neuropsychological rehabilitation programmes that could help improve current therapies.

Through the establishment of electronic health records, health education and measures such as regional information sharing platform, we explored the management of patients with alcohol dependence living in communities and established a medical information resource sharing model between mental hospital-community to strengthen the supportive intervention management of patients with alcohol dependence, improve the effect of intervention and reduce the rate of compound drink. To design the questionnaire of health state for patients with alcohol dependence. After data collection. We should establish electronic health records and community support intervention, make medical health card with terminal configuration card reader in both mental hospitals and community, develop information platform, establish a variety of supporting interventions and the service function modules, unblock information sharing between hospitals and community to make full use of the platform to carry out health education and health intervention management. The effectives of community supportive intervention are improved, rehabilitation rate of patients is reduced greatly, bad ways of life behavior are better. Establishing electronic health records is an important mean of community supportive interventions which is good for Real-time, dynamic management and promoting self-management skills making the dream of medical information resource between hospital-community sharing come true.

Emerging evidence indicates that dysfunctional glutamate neurotransmission is critical in the initiation and development of alcohol and drug dependence. Alcohol consumption induced downregulation of glutamate transporter 1 (GLT-1) as reported in previous studies from our laboratory. Glutamate is the major excitatory neurotransmitter in the brain, which acts via interactions with several glutamate receptors. Alcohol consumption interferes with the glutamatergic signal transmission by altering the functions of these receptors. Among the glutamate receptors involved in alcohol-drinking behavior are the metabotropic receptors such as mGluR1/5, mGluR2/3, and mGluR7, as well as the ionotropic receptors, NMDA and AMPA. Preclinical studies using agonists and antagonists implicate these glutamatergic receptors in the development of alcohol use disorder (AUD). Therefore, the purpose of this review is to discuss the neurocircuitry involving glutamate transmission in animals exposed to alcohol and further outline the role of metabotropic and ionotropic receptors in the regulation of alcohol-drinking behavior. This review provides ample information about the potential therapeutic role of glutamatergic receptors for the treatment of AUD. Copyright © 2017 Elsevier Ltd. All rights reserved.

Alcohol dependence is characterized as a multi-factorial disorder caused by a complex interaction between genetic and environmental liabilities across development. A variety of neurocognitive deficits/dysfunctions involving impairments in different brain regions and/or neural circuitries have been associated with chronic alcoholism, as well as with a predisposition to develop alcoholism. Several neurobiological and neurobehavioral approaches and methods of analyses have been used to understand the nature of these neurocognitive impairments/deficits in alcoholism. In the present review, we have examined relatively novel methods of analyses of the brain signals that are collectively referred to as event-related oscillations (EROs) and show promise to further our understanding of human brain dynamics while performing various tasks. These new measures of dynamic brain processes have exquisite temporal resolution and allow the study of neural networks underlying responses to sensory and cognitive events, thus providing a closer link to the physiology underlying them. Here, we have reviewed EROs in the study of alcoholism, their usefulness in understanding dynamical brain functions/dysfunctions associated with alcoholism as well as their utility as effective endophenotypes to identify and understand genes associated with both brain oscillations and alcoholism.

Alcohol is a teratogen that has diverse effects on brain and craniofacial development, leading to a constellation of developmental disorders referred to as fetal alcohol spectrum disorder (FASD). The molecular basis of ethanol insult remains poorly understood, as does the relationship between molecular and behavioral changes as a consequence of prenatal ethanol exposure. Zebrafish embryos were exposed to a range of ethanol concentrations (0.5–5.0%) during defined developmental stages, and examined for morphological phenotypes characteristic of FASD. Embryos were also analyzed by in situ hybridization for changes in expression of defined cell markers for neural cell types that are sonic hedgehog-dependent. We show that transient binge-like ethanol exposures during defined developmental stages, such as early gastrulation and early neurulation, result in a range of phenotypes and changes in expression of Shh-dependent genes. The severity of fetal alcohol syndrome (FAS) morphological phenotypes, such as microphthalmia, depends on the embryonic stage and concentration of alcohol exposure, as does diminution of retinal Pax6a or forebrain and hindbrain GAD1 gene expression. We also show that changes in eye and brain morphology correlate with changes in Pax6a and GAD1 gene expression. Our results therefore show that transient binge-like ethanol exposures in zebrafish embryos produce the stereotypical morphological phenotypes of FAS, with the severity of phenotypes depending on the developmental stage and alcohol concentration of exposure.

To investigate genetic and environmental influences on the development of specific alcohol dependence symptoms. A classical twin study of 3372 male-male twin pairs in the Vietnam Era Twin (VET) Registry based on telephone interviews about alcohol use. The nine diagnostic symptoms according to the Diagnostic and Statistical Manual of Mental Disorder, version III (revised) (DSM-III-R) definition of alcohol dependence. Symptoms were grouped into those based on impaired control, biological effects and social consequences (Beresford's classification) or early versus late symptoms (Nelson's classification). Survival models with random effects were used to examine the age of onset of each symptom. Approximately 38% of the variation in age of onset of each symptom group based on Beresford's classification is due to additive genetic factors. The age of onset of late symptoms from Nelson's classification appears to be most affected by genetic factors. Estimates of genetic effects for impaired control symptoms are greatly decreased when twins with comorbid psychiatric disorders are excluded. Our results support the heritability of age of onset of DSM-III-R-defined symptoms for alcohol dependence. However, no symptom group in Beresford's classification could be identified as more heritable than other symptom groups. A strong association between genetic vulnerability and co-occurring diseases for symptoms indicative of impaired control could be found. In addition, our findings show that the late symptom group could be a good candidate for subsequent genetic research.

Taking a step beyond prior alcohol research on pregnancy trimesters, we produced pregnancy month-specific drinking estimates for women in the United States in order to shed light on time variations of alcohol drinking during pregnancy, as might be determined by alcohol dependence. We posited that (a) pregnancy might prompt cessation of drinking soon after pregnancy status is discovered, a finding obscured in trimester-specific estimates, and (b) a possible alcohol-dependence effect on drinking persistence among pregnant women might be observed via the monthly approach. Data are from the 2002-2011 National Surveys on Drug Use and Health (Restricted-Data Analysis System [R-DAS]), with large nationally representative samples of U.S. civilians, including 12- to 44-year-old females stratified by pregnancy status and month of pregnancy, and with assessment of recent alcohol dependence as well as heavy episodic drinking (HED). Pregnancy's possibly protective constraints on drinking can be seen as early as Month 2. We observed considerable variability of drinking prevalence (%) before Trimester 1 ended, with no appreciable variation across Months 4-9. A possible alcohol-dependence effect on drinking persistence is seen when the contrast is made in relation to expected values for pregnant women without alcohol dependence. We detected a possibly ameliorative pregnancy effect on alcohol use and HED, with variation in drinking prevalence across the months of the first trimester. Alcohol dependence might be affecting drinking persistence among pregnant women, but this effect cannot account for the drinking persistence observed here.

A major barrier to successful treatment in alcohol dependence is psychiatric comorbidity. During treatment, the time to relapse is shorter, the drop-out rate is increased, and long-term alcohol consumption is greater for those with comorbid major depression or anxiety disorder than those with an alcohol use disorder with no comorbid mental disorder. The treatment of alcohol dependence and psychological disorders is often the responsibility of different services, and this can hinder the treatment process. Accordingly, there is a need for an effective integrated treatment for alcohol dependence and comorbid anxiety and/or depression. We aim to assess the effectiveness of a specialized, integrated intervention for alcohol dependence with comorbid anxiety and/or mood disorder using a randomized design in an outpatient hospital setting. Following a three-week stabilization period (abstinence or significantly reduced consumption), participants will undergo complete formal assessment for anxiety and depression. Those patients with a diagnosis of an anxiety and/or depressive disorder will be randomized to either 1) integrated intervention (cognitive behavioral therapy) for alcohol, anxiety, and/or depression; or 2) usual counseling care for alcohol problems. Patients will then be followed up at weeks 12, 16, and 24. The primary outcome measure is alcohol consumption (total abstinence, time to lapse, and time to relapse). Secondary outcome measures include changes in alcohol dependence severity, depression, or anxiety symptoms and changes in clinician-rated severity of anxiety and depression. The study findings will have potential implications for clinical practice by evaluating the implementation of specialized integrated treatment for comorbid anxiety and/or depression in an alcohol outpatient service.

Alcohol dependence is characterized by conflict between approach and avoidance motivational orientations for alcohol that operate in automatic and controlled processes. This article describes the first study to investigate the predictive validity of these motivational orientations for relapse to drinking after discharge from alcohol detoxification treatment in alcohol-dependent patients. One hundred twenty alcohol-dependent patients who were nearing the end of inpatient detoxification treatment completed measures of self-reported (Approach and Avoidance of Alcohol Questionnaire; AAAQ) and automatic (modified Stimulus-Response Compatibility task) approach and avoidance motivational orientations for alcohol. Their drinking behavior was assessed via telephone follow-ups at 2, 4, and 6 months after discharge from treatment. Results indicated that, after controlling for the severity of alcohol dependence, strong automatic avoidance tendencies for alcohol cues were predictive of higher percentage of heavy drinking days (PHDD) at 4-month (β = 0.22, 95% CI [0.07, 0.43]) and 6-month (β = 0.22, 95% CI [0.01, 0.42]) follow-ups. We failed to replicate previous demonstrations of the predictive validity of approach subscales of the AAAQ for relapse to drinking, and there were no significant predictors of PHDD at 2-month follow-up. In conclusion, strong automatic avoidance tendencies predicted relapse to drinking after inpatient detoxification treatment, but automatic approach tendencies and self-reported approach and avoidance tendencies were not predictive in this study. Our results extend previous findings and help to resolve ambiguities with earlier studies that investigated the roles of automatic and controlled cognitive processes in recovery from alcohol dependence.

Alcohol dependence (AD) is often accompanied by comorbid depression. Recent clinical evidence supports the benefit of subtype-specific pharmacotherapy in treating the population of alcohol-dependent subjects with comorbid major depressive disorder (MDD). However, in many alcohol-dependent subjects, depression is a reactive response to chronic alcohol use and withdrawal and abates with a period of abstinence. Genetic markers may distinguish alcohol-dependent subjects with MDD not tied chronologically and etiologically to their alcohol consumption. In this work, we investigated the association of adenylyl cyclase genes (ADCY1-9), which are implicated in both AD and mood disorders, with alcoholism and comorbid depression. Subjects from Vienna, Austria (n = 323) were genotyped, and single nucleotide polymorphisms (1,152) encompassing the genetic locations of the 9 ADCY genes were examined. The Vienna cohort contained alcohol-dependent subjects differentiated using the Lesch Alcoholism Typology. In this typology, subjects are segregated into 4 types. Type III alcoholism is distinguished by co-occurrence of symptoms of depression and by affecting predominantly females. We identified 4 haplotypes associated with the phenotype of Type III alcoholism in females. One haplotype was in a genomic area in proximity to ADCY2, but actually within a lincRNA gene, 2 haplotypes were within ADCY5, and 1 haplotype was within the coding region of ADCY8. Three of the 4 haplotypes contributed independently to Type III alcoholism and together generated a positive predictive value of 72% and a negative predictive value of 78% for distinguishing women with a Lesch Type III diagnosis versus women designated as Type I or II alcoholics. Polymorphisms in ADCY8 and ADCY5 and within a lincRNA are associated with an alcohol-dependent phenotype in females, which is distinguished by comorbid signs of depression. Each of these genetic locations can rationally contribute to the polygenic etiology of the alcoholism/depression phenotype, and the use of these genetic markers may aid in choosing appropriate and beneficial treatment strategies.

To determine whether nalmefene combined with psychosocial support is cost-effective compared with psychosocial support alone for reducing alcohol consumption in alcohol-dependent patients with high/very high drinking risk levels (DRLs) as defined by the WHO, and to evaluate the public health benefit of reducing harmful alcohol-attributable diseases, injuries and deaths. Decision modelling using Markov chains compared costs and effects over 5 years. The analysis was from the perspective of the National Health Service (NHS) in England and Wales. The model considered the licensed population for nalmefene, specifically adults with both alcohol dependence and high/very high DRLs, who do not require immediate detoxification and who continue to have high/very high DRLs after initial assessment. We modelled treatment effect using data from three clinical trials for nalmefene (ESENSE 1 (NCT00811720), ESENSE 2 (NCT00812461) and SENSE (NCT00811941)). Baseline characteristics of the model population, treatment resource utilisation and utilities were from these trials. We estimated the number of alcohol-attributable events occurring at different levels of alcohol consumption based on published epidemiological risk-relation studies. Health-related costs were from UK sources. We measured incremental cost per quality-adjusted life year (QALY) gained and number of alcohol-attributable harmful events avoided. Nalmefene in combination with psychosocial support had an incremental cost-effectiveness ratio (ICER) of £5204 per QALY gained, and was therefore cost-effective at the £20,000 per QALY gained decision threshold. Sensitivity analyses showed that the conclusion was robust. Nalmefene plus psychosocial support led to the avoidance of 7179 alcohol-attributable diseases/injuries and 309 deaths per 100,000 patients compared to psychosocial support alone over the course of 5 years. Nalmefene can be seen as a cost-effective treatment for alcohol dependence, with substantial public health benefits. This cost-effectiveness analysis was developed based on data from three randomised clinical trials: ESENSE 1 (NCT00811720), ESENSE 2 (NCT00812461) and SENSE (NCT00811941).

Crossmodal processing (i.e., the construction of a unified representation stemming from distinct sensorial modalities inputs) constitutes a crucial ability in humans' everyday life. It has been extensively explored at cognitive and cerebral levels during the last decade among healthy controls. Paradoxically however, and while difficulties to perform this integrative process have been suggested in a large range of psychopathological states (e.g., schizophrenia and autism), these crossmodal paradigms have been very rarely used in the exploration of psychiatric populations. The main aim of the present paper is thus to underline the experimental and clinical usefulness of exploring crossmodal processes in psychiatry. We will illustrate this proposal by means of the recent data obtained in the crossmodal exploration of emotional alterations in alcohol-dependence. Indeed, emotional decoding impairments might have a role in the development and maintenance of alcohol-dependence, and have been extensively investigated by means of experiments using separated visual or auditory stimulations. Besides these unimodal explorations, we have recently conducted several studies using audio-visual crossmodal paradigms, which has allowed us to improve the ecological validity of the unimodal experimental designs and to offer new insights on the emotional alterations among alcohol-dependent individuals. We will show how these preliminary results can be extended to develop a coherent and ambitious research program using crossmodal designs in various psychiatric populations and sensory modalities. We will finally end the paper by underlining the various potential clinical applications and the fundamental implications that can be raised by this emerging project. PMID:23898250

Alcohol dependence (AD) is one of the major elements that significantly influence drinking pattern that provoke the alcohol-induced organ damage. The structural and neurophysiologic abnormalities in the frontal lobes of chronic alcoholics were revealed by magnetic resonance imaging scans. It is well known that candidate genes involved in dopaminergic pathway are of immense interest to the researchers engaged in a wide range of addictive disorders. Dopaminergic pathway gene polymorphisms are being extensively studied with respect to addictive and behavioral disorders. From the broad literature available, the current review summarizes the specific polymorphisms of dopaminergic genes that play a role in alcohol dependence. No evidence indicating any strong association between AD and polymorphisms of dopamine pathway genes has emerged from the literature. Further studies are warranted, considering a range of alcohol-related traits to determine the genes that influence alcohol dependence.

A full account of two recently developed nickel-catalyzed coupling reactions of alkenes, aldehydes and silyl triflates is presented. These reactions provide either allylic alcohol or homoallylic alcohol derivatives selectively, depending on the ligand employed. These processes are believed to be mechanistically distinct from Lewis acid-catalyzed carbonyl-ene reactions, and several lines of evidence supporting this hypothesis are discussed. PMID:16939275

We recently demonstrated that moderate alcohol consumption is associated with a considerable reduction in the risk of autoimmune hypothyroidism, similar to findings in other autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. We aimed to study a possible association between alcohol intake and autoimmune Graves' hyperthyroidism. This is a population-based, case-control study. In a well-defined Danish population (2,027,208 person-years of observation), we prospectively identified patients with new overt thyroid dysfunction and studied 272 patients with Graves' hyperthyroidism. For each patient, we recruited four age-gender-region-matched controls with normal thyroid function (n = 1088). Participants gave detailed information on current and previous alcohol intake as well as other factors to be used for analyses. The association between alcohol intake and development of hyperthyroidism was analysed in conditional multivariate Cox regression models. Graves' patients had a lower reported alcohol consumption than controls (median units of alcohol (12 g) per week: 2 vs 4, P < 0·001). In a multivariate regression model, alcohol consumption was associated with a dose-dependent reduction in risk for development of overt Graves' hyperthyroidism. Odds ratios (95% confidence interval) compared with the reference group with a recent (last year) consumption of 1-2 units of alcohol per week were as follows: 0 units/week 1·73 (1·17-2·56), 3-10 units/week 0·56 (0·39-0·79), 11-20 units/week 0·37 (0·21-0·65), ≥21 units/week 0·22 (0·08-0·60). Similar results were found for maximum previous alcohol consumption during a calendar year. No interaction was found with the type of alcohol consumed (wine vs beer), smoking habit, age, gender or region of inhabitancy. Moderate alcohol consumption is associated with a considerable reduction in the risk of Graves' disease with hyperthyroidism--irrespective of age and gender. Autoimmune thyroid disease seems to be much more dependent on environmental factors than hitherto anticipated. © 2012 John Wiley & Sons Ltd.
Impaired decision-making under risk in individuals with alcohol dependence

Background Alcohol dependence is associated with poor decision-making under ambiguity, that is, when decisions are to be made in the absence of known probabilities of reward and loss. However, little is known regarding decisions made by individuals with alcohol dependence in the context of known probabilities (decision under risk). In this study, we investigated the relative contribution of these distinct aspects of decision making to alcohol dependence. Methods Thirty recently detoxified and sober asymptomatic alcohol-dependent individuals, and thirty healthy control participants were tested for decision-making under ambiguity (using the Iowa Gambling Task), and decision-making under-risk (using the Cups Task and Coin Flipping Task). We also tested their capacities for working memory storage (Digit-span Forward), and dual-tasking (Operation-span Task). Results Compared to healthy control participants, alcohol-dependent individuals made disadvantageous decisions on the Iowa Gambling Task, reflecting poor decisions under ambiguity. They also made more risky choices on the Cups and Coin Flipping Tasks reflecting poor decision-making under risk. In addition, alcohol-dependent participants showed some working memory impairments, as measured by the dual tasking, and the degree of this impairment correlated with high-risk decision-making, thus suggesting a relationship between processes sub-serving working memory and risky decisions. Conclusion These results suggest that alcohol dependent individuals are impaired in their ability to decide optimally in multiple facets of uncertainty (i.e., both risk and ambiguity), and that at least some aspects of these deficits are linked to poor working memory processes.

The present study investigated the nature of physiological cue reactivity and craving in response to alcohol cues among alcohol-dependent patients (N = 80) who were enrolled in detoxification treatment. Further, the predictive value with regard to future drinking of both the magnitude of the physiological and craving response to alcohol cues while in treatment and the degree of alcohol-cue exposure in patients' natural environment was assessed. Physiological reactivity and craving in response to experimental exposure to alcohol and soft drink advertisements were measured during detoxification treatment using heart rate variability and subjective rating of craving. Following discharge, patients monitored exposure to alcohol advertisements for five consecutive weeks with a diary and were followed up with an assessment of relapse at 5 weeks and 3 months post-discharge. The results indicated that the presence of alcohol cues such as the portrayal of the drug and drinking behaviour induced physiological cue reactivity and craving. Additionally, cue reactivity and craving were positively correlated, and cue reactivity was larger for patients with shorter histories of alcohol dependence. Further, patients reported a substantial daily exposure to alcohol cues. The magnitude of cue reactivity and the craving response to alcohol cues at baseline and degree of exposure to alcohol cues in patients' natural environment did not predict relapse. It is concluded that the presence of alcohol cues such as portrayal of alcoholic beverages and drinking behaviour induces cue reactivity and craving in alcohol dependence through a conditioned appetitive response.

Energy drinks are highly caffeinated beverages that are increasingly consumed by young adults. Prior research has established associations between energy drink use and heavier drinking and alcohol-related problems among college students. This study investigated the extent to which energy drink use might pose additional risk for alcohol dependence over and above that from known risk factors. Data were collected via personal interview from 1,097 fourth-year college students sampled from 1 large public university as part of an ongoing longitudinal study. Alcohol dependence was assessed according to DSM-IV criteria. After adjustment for the sampling design, 51.3%(wt) of students were classified as "low-frequency" energy drink users (1 to 51 days in the past year) and 10.1%(wt) as "high-frequency" users (≥52 days). Typical caffeine consumption varied widely depending on the brand consumed. Compared to the low-frequency group, high-frequency users drank alcohol more frequently (141.6 vs. 103.1 days) and in higher quantities (6.15 vs. 4.64 drinks/typical drinking day). High-frequency users were at significantly greater risk for alcohol dependence relative to both nonusers (AOR = 2.40, 95% CI = 1.27 to 4.56, p = 0.007) and low-frequency users (AOR = 1.86, 95% CI = 1.10, 3.14, p = 0.020), even after holding constant demographics, typical alcohol consumption, fraternity/sorority involvement, depressive symptoms, parental history of alcohol/drug problems, and childhood conduct problems. Low-frequency energy drink users did not differ from nonusers on their risk for alcohol dependence. Weekly or daily energy drink consumption is strongly associated with alcohol dependence. Further research is warranted to understand the possible mechanisms underlying this association. College students who frequently consume energy drinks represent an important target population for alcohol prevention. Copyright © 2010 by the Research Society on Alcoholism.

Previous studies on acetaldehyde dehydrogenase 2 (ALDH2) focused on drinking behavior or alcoholism because the ALDH2*2 allele protects against the risk of developing alcoholism. The mechanism provides that the ALDH2 gene's protective effect is also involved in dopamine metabolism. The interaction of the ALDH2 gene with neurotransmitters, such as dopamine, is suggested to be related to alcoholism. Because alcoholism is often co-morbid with antisocial personality disorder (ASPD), previous association studies on antisocial alcoholism cannot differentiate whether those genes relate to ASPD with alcoholism or ASPD only. This study examined the influence of the interaction effect of the ALDH2*1*1, *1*2 or *2*2 polymorphisms with the dopamine 2 receptor (DRD2) Taq I polymorphism on ASPD. Our 541 Han Chinese male participants were classified into three groups: antisocial alcoholism (ASPD co-morbid with alcohol dependence, antisocial ALC; n = 133), ASPD without alcoholism (ASPD not co-morbid with alcohol dependence, antisocial non-ALC; n = 164) and community controls (healthy volunteers from the community; n = 244). Compared with healthy controls, individuals with the DRD2 A1/A1 and the ALDH2*1/*1 genotypes were at a 5.39 times greater risk for antisocial non-ALC than were those with other genotypes. Our results suggest that the DRD2/ANKK1 and ALDH2 genes interacted in the antisocial non-ALC group; a connection neglected in previous studies caused by not separating antisocial ALC from ASPD. Our study made this distinction and showed that these two genes may be associated ASPD without co-morbid alcoholism. © 2010 The Authors, Addiction Biology © 2010 Society for the Study of Addiction.

Alcoholism is a chronic psychiatric disorder affecting neural pathways that regulate motivation, stress, reward and arousal. Brain-derived neurotrophic factor (BDNF) regulates mood, response to stress and interacts with neurotransmitters and stress systems involved in reward pathways and addiction. Aim of the study was to evaluate the association between a single nucleotide polymorphism (BDNF Val66Met or rs6265) and alcohol related phenotypes in Caucasian patients. In ethnically homogenous Caucasian subjects of the Croatian origin, the BDNF Val66Met genotype distribution was determined in 549 male and 126 female patients with alcohol dependence and in 655 male and 259 female healthy non-alcoholic control subjects. Based on the structured clinical interview, additional detailed clinical interview, the Brown-Goodwin Scale, the Hamilton Rating Scale for Depression and the Clinical Global Impression scores, alcoholic patients were subdivided into those with or without comorbid depression, aggression, delirium tremens, withdrawal syndrome, early/late onset of alcohol abuse, prior suicidal attempt during lifetime, current suicidal behavior, and severity of alcohol dependence. The results showed no significant association between BDNF Val66Met variants and alcohol dependence and/or any of the alcohol related phenotypes in either Caucasian women, or men, with alcohol dependence. There are few limitations of the study. The overall study sample size was large (N=1589) but not well-powered to detect differences in BDNF Val66Met genotype distribution between studied groups. Healthy control women were older than female alcoholic patients. Only one BDNF polymorphism (rs6265) was studied. In conclusion, these data do not support the view that BDNF Val66Met polymorphism correlates with the specific alcohol related phenotypes in ethnically homogenous medication-free Caucasian subjects with alcohol dependence.

This article assesses the ability of the economic outcome measures in the Economic Form 90 to detect differences across levels of alcohol dependence as measured by the Alcohol Dependence Scale. We used baseline data from the Combining Medications and Behavioral Interventions (COMBINE) Study, a large, multisite clinical trial, to assess the extent to which the economic items on the Economic Form 90 instrument can detect differences across levels of alcohol dependence. After adjusting for differences in demographic characteristics, the Economic Form 90 can detect significant differences across a range of dependence severity levels for the economic outcomes of inpatient medical care, emergency-department medical care, behavioral health care, being on parole or probation, and missed workdays, conditional on being employed. We did not detect significant differences across dependence severity for employment status, outpatient medical care, other criminal justice involvement, or motor vehicle accidents. The Economic Form 90 can identify differences in many economic outcomes associated with differing levels of alcohol dependence. This suggests that the Economic Form 90 may be useful in assessing changes in economic outcomes that result from changes in alcohol dependence.
Genetic and epigenetic insights into fetal alcohol spectrum disorders
2010-01-01
The magnitude of the detrimental effects following in utero alcohol exposure, including fetal alcohol syndrome and other fetal alcohol spectrum disorders (FASD), is globally underestimated. The effects include irreversible cognitive and behavioral disabilities as a result of abnormal brain development, pre- and postnatal growth retardation and facial dysmorphism. Parental alcohol exposure and its effect on offspring has been recognized for centuries, but only recently have we begun to gain molecular insight into the mechanisms involved in alcohol teratogenesis. Genetic attributes (susceptibility and protective alleles) of the mother and the fetus contribute to the risk of developing FASD and specific additional environmental conditions, including malnutrition, have an important role. The severity of FASD depends on the level of alcohol exposure, the developmental stage at which exposure occurs and the nature of the exposure (chronic or acute), and although the most vulnerable period is during the first trimester, damage can occur throughout gestation. Preconception alcohol exposure can also have a detrimental effect on the offspring. Several developmental pathways are affected in FASD, including nervous system development, growth and remodeling of tissues, as well as metabolic pathways that regulate glucocorticoid signaling and balanced levels of retinol, insulin and nitric oxide. A body of knowledge has accumulated to support the role of environmentally induced epigenetic remodeling during gametogenesis and after conception as a key mechanism for the teratogenic effects of FASD that persist into adulthood. Transgenerational effects are likely to contribute to the global burden of alcohol-related disease. FASD results in lifelong disability and preventative programs should include both maternal alcohol abstention and preconception alcohol avoidance. PMID:20423530

This article highlights the research presentations at the satellite symposium on "Brain Pathways to Recovery from Alcohol Dependence" held at the 2013 Society for Neuroscience Annual Meeting. The purpose of this symposium was to provide an up to date overview of research efforts focusing on understanding brain mechanisms that contribute to recovery from alcohol dependence. A panel of scientists from the alcohol and addiction research field presented their insights and perspectives on brain mechanisms that may underlie both recovery and lack of recovery from alcohol dependence. The four sessions of the symposium encompassed multilevel studies exploring mechanisms underlying relapse and craving associated with sustained alcohol abstinence, cognitive function deficit and recovery, and translational studies on preventing relapse and promoting recovery. Gaps in our knowledge and research opportunities were also discussed. Published by Elsevier Inc.

The adverse effects of alcohol on brain function result, in part, from inflammatory processes. The sex-specific neuropsychiatric consequences and inflammatory status of active alcohol dependence and early remission from dependence have not been investigated. Neuropsychiatric symptoms, inflammatory factors, and liver enzymes were compared in a prospective cohort study of adults with (n=51) or without (n=31) a current or recent history of alcohol dependence. Neuropsychiatric profiles were similar in adults with current or recent alcohol dependence regardless of sex. In male and female participants measures of depression (female p<0.05, male p<0.001), anxiety (female p<0.001, male p<0.001), and memory complaints (female p<0.001, male p<0.05) were elevated, relative to non-dependent controls. Significant sex×alcohol dependence history interactions were observed for plasma levels of tissue inhibitor of metalloproteinase 1 (TIMP-1) and brain derived neurotrophic factor (BDNF), with women in the alcohol dependent group exhibiting increased levels of both analytes (p<0.05) relative to controls. Positive correlations between TIMP-1 levels and measures of depression (r 2 =0.35, p<0.01), anxiety (r 2 =0.24, p<0.05) and memory complaints (r 2 =0.44, p<0.01) were found in female, but not male, participants. Though neuropsychiatric profiles were similar for men and women with current or recent alcohol dependence, plasma factors associated with increases in depression, anxiety, and memory impairment differed and support the need to tailor treatments based on sex.

Neurotoxic Effects of Alcohol in Adolescence
Jacobus, Joanna; Tapert, Susan F.
2013-01-01
This review examines neuroimaging and neurocognitive findings on alcohol-related toxicity in adolescents. Teens who meet criteria for alcohol use disorders, as well as those who engage in subdiagnostic binge drinking behaviors, often show poorer neurocognitive performance, alterations in gray and white matter brain structure, and discrepant functional brain activation patterns when compared to nonusing and demographically matched controls. Abnormalities are also observed in teens with a family history of alcoholism, and such differences in neuromaturation may leave youths at increased risk for the development of an alcohol use disorder or increased substance use severity. More prospective investigations are needed, and future work should focus on disentangling preexisting differences from dose-dependent effects of alcohol on neurodevelopment. Intervention strategies that utilize neuroimag-ing findings (e.g., identified weaknesses in particular neural substrates and behavioral correlates) may be helpful in both prevention and intervention campaigns for teens both pre- and postinitiation of alcohol use.

Globally, alcohol-abuse is a major cause of mortality and morbidity. Consumption of alcohol has increased in India in the recent decades. It is imperative to know the patterns of alcohol consumption among different types of consumers to launch a well-planned nationwide programme for the prevention and control of this devastating social pathology. This community-based, cross-sectional study was undertaken to identify the patterns of alcohol intake among different types of alcohol consumers and to assess the clinical signs of chronic harmful alcohol-use. A predesigned, pretested, semi-structured alcohol-use disorders identification test (AUDIT) questionnaire was used for interviewing males, aged >18 years, selected by random sampling from an updated household list of a randomly-selected sector of the service area of the Urban Health Centre in Chetla, Kolkata, West Bengal, India. Written informed consents were obtained from all the respondents. Relevant clinical examination for chronic harmful alcohol-use was done according to the AUDIT clinical screening procedures. The results revealed that 65.8% (150/228) were current consumers of alcohol; 14% were alcohol-dependents; 8% were hazardous or harmful consumers, and 78% were non-hazardous non-harmful consumers. The mean age of the respondents at the initiation of drinking alcohol was 20.8+5.9 years. Eighty-six percent of dependents (n=21) took both Indian-made foreign liquor and locally-made alcoholic beverages. The proportions of alcohol consumers who drank alone among alcohol-dependents, hazardous or harmful consumers, and non-hazardous non-harmful consumers were 71.4%, 50%, and 7.7% respectively, and the difference was significant (p<0.01). Forty-one percent of the consumers drank at public places and workplaces, which may be socially harmful. About 38% of the dependents purchased alcohol from unlicensed liquor shops. Only 16% expressed concerns for their drinking habit mainly to the past illness. The proportion of the concerned respondents was higher in the hazardous and harmful drinking patterns than in the non-hazardous non-harmful drinking pattern, and the difference was significant (p<0.05). About 62% of the dependents had clinical signs of chronic alcohol consumption. The presence of a considerable proportion of alcohol-dependents, the low mean age at initiation of drinking alcohol, and the habit of drinking in public places and workplaces are the main areas that need special emphasis by intervention programmes.

Central ghrelin signaling is required for the rewarding effects of alcohol in mice. Because ghrelin is implied in other addictive behaviors such as eating disorders and smoking, and because there is co-morbidity between these disorders and alcohol dependence, the ghrelin signaling system could be involved in mediating reward in general. Furthermore, in humans, single nucleotide polymorphisms (SNPs) and haplotypes of the pro-ghrelin gene (GHRL) and the ghrelin receptor gene (GHSR) have previously been associated with increased alcohol consumption and increased body weight. Known gender differences in plasma ghrelin levels prompted us to investigate genetic variation of the ghrelin signaling system in females with severe alcohol dependence (n = 113) and in a selected control sample of female low-consumers of alcohol from a large cohort study in southwest Sweden (n = 212). Six tag SNPs in the GHRL (rs696217, rs3491141, rs4684677, rs35680, rs42451, and rs26802) and four tag SNPs in the GHSR (rs495225, rs2232165, rs572169, and rs2948694) were genotyped in all individuals. We found that one GHRL haplotype was associated with reports of paternal alcohol dependence as well as with reports of withdrawal symptoms in the female alcohol-dependent group. Associations with 2 GHSR haplotypes and smoking were also shown. One of these haplotypes was also negatively associated with BMI in controls, while another haplotype was associated with having the early-onset, more heredity-driven, type 2 form of alcohol dependence in the patient group. Taken together, the genes encoding the ghrelin signaling system cannot be regarded as major susceptibility genes for female alcohol dependence, but is, however, involved in paternal heritability and may affect other reward- and energy-related factors such as smoking and BMI.

The burden of alcohol misuse is unknown among shipboard U.S. Navy and Marine Corps military personnel immediately prior to deployment and may be elevated. Anonymous survey data on hazardous, dependent, and binge alcohol misuse and involuntary drug consumption were collected during 2012-2014 among shipboard personnel within approximately 2 weeks of deployment. Using the Alcohol Use Disorders Identification Test Consumption (AUDIT-C), hazardous alcohol misuse was defined using two cut-point scoring criteria: (1) ≥3 for women and ≥4 for men; and (2) ≥4 for women and ≥5 for men; binge drinking as ≥4 drinks for women and ≥5 drinks for men on a typical day in past 30 days; and dependent alcohol misuse as an AUDIT-C score of ≥8. Demographic- and sex-stratified self-reported alcohol misuse prevalence was reported for analysis conducted during 2014-2015. Among 2,351 male and female shipboard personnel, 39%-54% screened positive for hazardous, 27% for binge, and 15% for dependent alcohol use. Seven percent reported involuntary drug consumption history. A larger proportion of those aged 17-20 years screened positive for dependent alcohol use compared with the overall study population prevalence. A large proportion of shipboard personnel screened positive for hazardous and dependent alcohol use (18% among those aged <21 years) at deployment onset. These data can inform interventions targeting shipboard personnel engaging in hazardous use before progression to dependent use and enable early identification and care for dependent users. Future studies should include more comprehensive assessment of factors associated with involuntary drug consumption. Copyright © 2016 American Journal of Preventive Medicine. All rights reserved.

Clinicians caring for patients seeking alcohol detoxification face many challenges, including lack of evidence-based guidelines for treatment and high recidivism rates. To develop a standardized protocol for determining which alcohol dependent patients seeking detoxification need inpatient versus outpatient treatment, and to study the protocol's implementation. Review of best evidence by ad hoc task force and subsequent creation of standardized protocol. Prospective observational evaluation of initial protocol implementation. Patients presenting for alcohol detoxification. Development and implementation of a protocol for evaluation and treatment of patients requesting alcohol detoxification. Number of admissions per month with primary alcohol related diagnosis (DRG), 30-day readmission rate, and length of stay, all measured before and after protocol implementation. We identified one randomized clinical trial and three cohort studies to inform the choice of inpatient versus outpatient detoxification, along with one prior protocol in this population, and combined that data with clinical experience to create an institutional protocol. After implementation, the average number of alcohol related admissions was 15.9 per month, compared with 18.9 per month before implementation (p = 0.037). There was no difference in readmission rate or length of stay. Creation and utilization of a protocol led to standardization of care for patients requesting detoxification from alcohol. Initial evaluation of protocol implementation showed a decrease in number of admissions.

Objective This study identifies and compares outcomes in young adulthood associated with longitudinal patterns of alcohol and marijuana use during adolescence among urban youth. Method Data come from a cohort of 678 urban, predominantly Black children followed from ages 6–25 (1993–2012). Analyses are based on the 608 children who participated over time (53.6% male). Longitudinal patterning of alcohol and marijuana use were based on annual frequency reports from grades 8–12 and estimated through latent profile analysis. Results We identified four classes of alcohol and marijuana use including Non-Use (47%), Moderate Alcohol Use (28%), Moderate Alcohol/Increasing Marijuana Use (12%) and High Dual Use (13%). A marijuana only class was not identified. Analyses show negative outcomes in adulthood associated with all three adolescent substance use classes. Compared to the non-use class, all use classes had statistically significantly higher rates of substance dependence. Those in the ‘High Dual Use’ class had the lowest rate of high school graduation. Comparing classes with similar alcohol but different marijuana patterns, the ‘Moderate Alcohol/Increasing Marijuana Use’ class had a statistically significant increased risk of having a criminal justice record and developing substance use dependence in adulthood. Conclusion Among urban youth, heterogeneous patterns of alcohol and marijuana use across adolescence are evident, and these patterns are associated with distinct outcomes in adulthood. These findings suggest a need for targeted education and intervention efforts to address the needs of youth using both marijuana and alcohol, as well as the importance of universal early preventive intervention efforts.

Baclofen has been suggested as a potential pharmacotherapy for alcohol use disorder, but the clinical data are conflicting. Here we investigated the biobehavioral effects of baclofen in a sample of anxious alcohol-dependent individuals. This was a randomized, double-blind, placebo-controlled, human laboratory study in non-treatment seeking alcohol-dependent individuals with high trait anxiety (N=34). Participants received baclofen (30 mg per day) or placebo for at least 8 days, then performed an experimental session consisting of alcohol cue-reactivity followed by alcohol administration procedure (alcohol priming, then alcohol self-administration). Total amount of alcohol self-administered was the primary outcome; alcohol craving, subjective/physiological responses and mood/anxiety symptoms were also evaluated. There was no significant medication effect on the total amount of alcohol consumed during the alcohol self-administration (P=0.76). Baclofen blunted the positive association between maximum breath alcohol concentration during priming and the amount of alcohol consumption (significant interaction, P=0.03). Ratings of feeling intoxicated were significantly higher in the baclofen group after consuming the priming drink (P=0.006). During the self-administration session, baclofen significantly increased ratings of feeling high (P=0.01) and intoxicated (P=0.01). A significant reduction in heart rate (P<0.001) and a trend-level increase in diastolic blood pressure (P=0.06) were also detected in the baclofen group during the alcohol laboratory session. In conclusion, baclofen was shown to affect subjective and physiological responses to alcohol drinking in anxious alcohol-dependent individuals. These results do not support an anti-craving or anti-reinforcing effect of baclofen, but rather suggest that baclofen may act as a substitution medication for alcohol use disorder. PMID:28440812

This study tested the hypothesis that adolescent-onset alcohol abuse (AOAA) would both mediate and moderate the effect of childhood conduct disorder on antisocial behaviour in late adolescence and early adulthood. A sample comprising 504 young men and women strategically recruited from the community were grouped using the criteria of the Diagnostic and Statistical Manual (DSM-IV, American Psychiatric Association. (1994). Diagnostic and statistical manual of mental disorders (4th ed.). Washington, DC: APA), as follows: neither childhood conduct disorder (CCD) nor alcohol abuse/dependence; CCD but no alcohol abuse or dependence; alcohol abuse/dependence but no CCD; both CCD and alcohol abuse/dependence. The outcome measure was the sum of positive responses to 55 interview items capturing a variety of antisocial behaviours engaged in since age 15. Severity of lifetime alcohol-related and CCD problems served as predictor variables in regression analysis. Antisocial behaviour problems were greatest in individuals with a history of co-occurring conduct disorder (CD) and alcohol abuse/dependence. While CCD was strongly predictive of adult antisocial behaviour, this effect was both mediated and moderated (exacerbated) by AOAA.

Objective: Using insights from Ecological Systems Theory and Reinforcement Sensitivity Theory, the current study assessed the utility of a series of hypothetical role-based alcohol-consumption scenarios that varied in their presentation of rewarding and punishing information. Method: The scenarios, along with measures of impulsive sensation seeking and a self-report of weekly alcohol consumption, were administered to a sample of alcohol-dependent and non-alcohol-dependent college-age individuals (N = 170). Results: The results showed scenario attendance decisions were largely unaffected by alcohol-dependence status and variations in contextual reward and punishment information. In contrast to the attendance findings, the results for the alcohol-consumption decisions showed alcohol-dependent individuals reported a greater frequency of deciding to drink, as well as indicating greater alcohol consumption in the contexts of complementary rewarding or nonpunishing information. Regression results provided evidence for the criterion-related validity of scenario outcomes in an account of diagnostic alcohol problems. Conclusions: The results are discussed in terms of the conceptual and predictive gains associated with an assessment approach to alcohol-consumption decision making that combines situational information organized and balanced through the frameworks of Ecological Systems Theory and Reinforcement Sensitivity Theory.

Little research has been done on alcohol use and dependence among rural residents in China, a sub-population that might be under increased stress due to the rapid modernization and urbanization processes. We aimed to assess rural residents' levels of stress, negative emotions, resilience, alcohol use/dependence and the complex relationships among them. Survey data from a large random sample (n=1145, mean age=35.9, SD=7.7, 50.7% male) of rural residents in Wuhan, China were collected using Audio Computer-Assisted Self-Interview. The sample had high prevalence of frequently perceived stress (47%) and high prevalence of ever (54.4%), past 30-day (40.4%), and binge drinking (13.8%). Approximately 11% met the criterion for intermediate to severe alcohol dependence. Mediation analysis indicated that the association between perceived stress (predictor) and alcohol dependence (outcome) was fully mediated by anxiety (indirect effect=.203, p<.01) and depression (indict effect=.158, p<.05); moderation analysis indicated that association between stress and two negative emotions (mediators) was significantly modified by resilience (moderator); an integrative moderated mediation analysis indicated that the indirect effect from stress to alcohol dependence through negative emotions was also moderated by resilience. Negative emotions play a key role in bridging stress and alcohol dependence, while resilience significantly buffers the impact of stress on depression, reducing the risk of alcohol dependence. Resilience training may be an effective component for alcohol intervention in rural China. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.
Tobacco smoking interferes with GABAA receptor neuroadaptations during prolonged alcohol withdrawal

Understanding the effects of tobacco smoking on neuroadaptations in GABAA receptor levels over alcohol withdrawal will provide critical insights for the treatment of comorbid alcohol and nicotine dependence. We conducted parallel studies in human subjects and nonhuman primates to investigate the differential effects of tobacco smoking and nicotine on changes in GABAA receptor availability during acute and prolonged alcohol withdrawal. We report that alcohol withdrawal with or without concurrent tobacco smoking/nicotine consumption resulted in significant and robust elevations in GABAA receptor levels over the first week of withdrawal. Over prolonged withdrawal, GABAA receptors returned to control levels in alcohol-dependent nonsmokers, but alcohol-dependent smokers had significant and sustained elevations in GABAA receptors that were associated with craving for alcohol and cigarettes. In nonhuman primates, GABAA receptor levels normalized by 1 mo of abstinence in both groups—that is, those that consumed alcohol alone or the combination of alcohol and nicotine. These data suggest that constituents in tobacco smoke other than nicotine block the recovery of GABAA receptor systems during sustained alcohol abstinence, contributing to alcohol relapse and the perpetuation of smoking.

Stress has long been suggested to be an important correlate of uncontrolled drinking and relapse. An important hormonal response system to stress—the hypothalamic–pituitary–adrenal (HPA) axis—may be involved in this process, particularly stress hormones known as glucocorticoids and primarily cortisol. The actions of this hormone system normally are tightly regulated to ensure that the body can respond quickly to stressful events and return to a normal state just as rapidly. The main determinants of HPA axis activity are genetic background, early-life environment, and current life stress. Alterations in HPA axis regulation are associated with problematic alcohol use and dependence; however, the nature of this dysregulation appears to vary with respect to stage of alcohol dependence. Much of this research has focused specifically on the role of cortisol in the risk for, development of, and relapse to chronic alcohol use. These studies found that cortisol can interact with the brain’s reward system, which may contribute to alcohol’s reinforcing effects. Cortisol also can influence a person’s cognitive processes, promoting habit-based learning, which may contribute to habit formation and risk of relapse. Finally, cortisol levels during abstinence may be useful clinical indicators of relapse vulnerability in alcohol-dependent people. PMID:23584113

Addiction is supposedly characterized by a shift from goal-directed to habitual decision making, thus facilitating automatic drug intake. The two-step task allows distinguishing between these mechanisms by computationally modeling goal-directed and habitual behavior as model-based and model-free control. In addicted patients, decision making may also strongly depend upon drug-associated expectations. Therefore, we investigated model-based versus model-free decision making and its neural correlates as well as alcohol expectancies in alcohol-dependent patients and healthy controls and assessed treatment outcome in patients. Ninety detoxified, medication-free, alcohol-dependent patients and 96 age- and gender-matched control subjects underwent functional magnetic resonance imaging during the two-step task. Alcohol expectancies were measured with the Alcohol Expectancy Questionnaire. Over a follow-up period of 48 weeks, 37 patients remained abstinent and 53 patients relapsed as indicated by the Alcohol Timeline Followback method. Patients who relapsed displayed reduced medial prefrontal cortex activation during model-based decision making. Furthermore, high alcohol expectancies were associated with low model-based control in relapsers, while the opposite was observed in abstainers and healthy control subjects. However, reduced model-based control per se was not associated with subsequent relapse. These findings suggest that poor treatment outcome in alcohol dependence does not simply result from a shift from model-based to model-free control but is instead dependent on the interaction between high drug expectancies and low model-based decision making. Reduced model-based medial prefrontal cortex signatures in those who relapse point to a neural correlate of relapse risk. These observations suggest that therapeutic interventions should target subjective alcohol expectancies. Copyright © 2017 Society of Biological Psychiatry. Published by Elsevier Inc.

Nicotine Dependence and Alcohol Problems from Adolescence to Young Adulthood.
Dierker, Lisa; Selya, Arielle; Rose, Jennifer; Hedeker, Donald; Mermelstein, Robin
Despite the highly replicated relationship between symptoms associated with both alcohol and nicotine, little is known about this association across time and exposure to both drinking and smoking. In the present study, we evaluate if problems associated with alcohol use are related to emerging nicotine dependence symptoms and whether this relationship varies from adolescence to young adulthood, after accounting for both alcohol and nicotine exposure. The sample was drawn from the Social and Emotional Contexts of Adolescent Smoking Patterns Study which measured smoking, nicotine dependence, alcohol use and alcohol related problems over 6 assessment waves spanning 6 years. Analyses were based on repeated assessment of 864 participants reporting some smoking and drinking 30 days prior to individual assessment waves. Mixed-effects regression models were estimated to examine potential time, smoking and/or alcohol varying effects in the association between alcohol problems and nicotine dependence. Inter-individual differences in mean levels of alcohol problems and within subject changes in alcohol problems from adolescence to young adulthood were each significantly associated with nicotine dependence symptoms over and above levels of smoking and drinking behaviour. This association was consistent across both time and increasing levels of smoking and drinking. Alcohol related problems are a consistent risk factor for nicotine dependence over and above measures of drinking and smoking and this association can be demonstrated from the earliest experiences with smoking in adolescents, through the establishment of more regular smoking patterns across the transition to young adulthood. These findings add to accumulating evidence suggesting that smoking and drinking may be related through a mechanism that cannot be wholly accounted for by exposure to either substance.

Our aim was to describe alcohol consumption behavior of male Latino migrant farmworkers, compare their alcohol consumption behavior with that of other male Latino immigrants, and determine factors associated with risk for alcohol dependence among Latino immigrant workers. Cross-sectional data were drawn from baseline interviews conducted as part of a larger community-based participatory research project examining the cognitive and neurological outcomes of pesticide exposure. A total of 235 farmworkers and 212 nonfarmworkers completed interviews between May and August 2012. Although 17.5% of the North Carolina Latino farmworkers report never having drunk alcohol, and a total of 34.5% report not having drunk alcohol in the previous 3 months, 48.5% engaged in heavy episodic drinking (HED) in the previous 3 months, and 23.8% frequently engaged in HED during this period. Farmworkers and nonfarmworkers did not differ significantly in alcohol consumption behavior. Farmworkers and nonfarmworkers did differ significantly in each component of the CAGE scale, with 37.9% of farmworkers and 16.0% of nonfarmworkers being at risk for alcohol dependence (p < 0.0001). Significant factors for being at risk for alcohol dependence were stress (odds ratio 1.06, 95% confidence interval 1.03, 1.09) and being a farmworker (odds ratio 3.58, 95% confidence interval 2.12, 6.06). Being married reduced the risk of alcohol dependence (odds ratio 0.45, 95% confidence interval 0.23, 0.87). Latino farmworkers and nonfarmworkers consume relatively large amounts of alcohol and engage in HED at relatively high rates. Latino farmworkers have very high rates of risk for alcohol dependence. Policy changes and public health interventions are needed to address these concerns for a population that is vital to the agricultural economy. Copyright © 2016 by the Research Society on Alcoholism.
Gender and Impulsivity: Effects on Cue-Induced Alcohol Craving.

2016-05-01
Numerous studies have demonstrated that trait impulsivity is linked to increased risk of developing alcohol-use disorders and other substance abuse. Impulsivity has also been shown in some studies to potentiate cue-induced drug cravings. Despite considerable evidence of gender differences in impulsivity and drug craving among individuals suffering from alcohol dependence and other drug use, little research has focused on these processes in healthy young men and women who may be at risk for developing alcohol-use disorders. The objective of this study was to investigate the relationship between impulsivity and cue-induced craving, as well as possible gender differences in these effects among healthy young adults. To that end, female (n = 22) and male (n = 14) social drinkers aged 18 to 25, recruited from an urban university campus, completed the Barratt Impulsiveness Scale and reported their alcohol cravings immediately before and after laboratory exposure to alcohol cues. Findings indicated that exposure to cues elicited increased alcohol cravings, but these effects did not differ by gender. Interestingly, a significant interaction of impulsivity and gender revealed that impulsivity predicted significantly higher cue-induced cravings in women, but not men. Findings underscore the importance of better understanding the interaction of situational factors (e.g., exposure to alcohol cues) and dispositional factors (e.g., impulsivity) as potential contributors to drinking motivation. Future prospective research is needed to identify gender-specific risk factors for the development of problem drinking. Copyright © 2016 by the Research Society on Alcoholism.

Previous research has documented a relationship between child sexual abuse and alcohol dependence. This paper extends that work by providing a comprehensive description of past year and lifetime alcohol consumption patterns, consequences, and dependence among women reporting either physical and sexual abuse in a national sample. This study used survey data from 3,680 women who participated in the 2005 U.S. National Alcohol Survey. Information on physical and sexual child abuse and its characteristics were assessed in relation to 8 past year and lifetime alcohol consumption measures. Child physical or sexual abuse was significantly associated with past year and lifetime alcohol consumption measures. In multivariate analyses, controlling for age, marital status, employment status, education, ethnicity, and parental alcoholism or problem drinking, women reporting child sexual abuse vs. no abuse were more likely to report past year heavy episodic drinking (OR(adj) = 1.7; 95% CI 1.0 to 2.9), alcohol dependence (OR(adj) = 7.2; 95% CI 3.2 to 16.5), and alcohol consequences (OR(adj) = 3.6; 95% CI 1.8 to 7.3). Sexual abuse (vs. no abuse) was associated with a greater number of past year drinks (124 vs. 74 drinks, respectively, p = 0.002). Sexual child abuse was also associated with lifetime alcohol-related consequences (OR(adj) = 3.5; 95% CI 2.6 to 4.8) and dependence (OR(adj) = 3.7; 95% CI 2.6 to 5.3). Physical child abuse was associated with 4 of 8 alcohol measures in multivariate models. Both physical and sexual child abuse were associated with getting into fights, health, legal, work, and family alcohol-related consequences. Alcohol-related consequences and dependence were more common for women reporting sexual abuse compared to physical abuse, 2 or more physical abuse perpetrators, nonparental and nonfamily physical abuse perpetrators, and women reporting injury related to the abuse. Both child physical and sexual abuse were associated with many alcohol outcomes in adult women, even when controlling for parental alcohol problems. The study results point to the need to screen for and treat underlying issues related to child abuse, particularly in an alcohol treatment setting.

Discrete time survival analysis (DTSA) was used to assess the age-specific association of event related oscillations (EROs) and CHRM2 gene variants on the onset of regular alcohol use and alcohol dependence. The subjects were 2938 adolescents and young adults ages 12 to 25. Results showed that the CHRM2 gene variants and ERO risk factors had hazards which varied considerably with age. The bulk of the significant age-specific associations occurred in those whose age of onset was under 16. These associations were concentrated in those subjects who at some time took an illicit drug. These results are consistent with studies which associate greater rates of alcohol dependence among those who begin drinking at an early age. The age specificity of the genetic and neurophysiological factors is consistent with recent studies of adolescent brain development, which locate an interval of heightened vulnerability to substance use disorders in the early to mid teens.

Alcohol concentration dependences of photoinduced charge separation (CS) reaction of zinc tetraphenyl-porphyrin (ZnTPP) and duroquinone (DQ) were investigated in benzonitrile by a nanosecond laser flash photolysis technique. The photoinduced CS reaction was accelerated by the addition of alcohols, whereas the addition of acetonitrile caused little effect on the CS reactions. The simple theory was developed to calculate an increase in reorganization energies induced by the hydrogen bonding interactions between DQ and alcohols using the chemical equilibrium constants for the hydrogen bonding complexes through the concerted pathway and the stepwise one. The experimental results were analyzed by using the Marcus equation where we took into account the hydrogen bonding effects on the reorganization energy and the reaction free energy for the CS reaction. The observed alcohol concentration dependence of the CS reaction rates was well explained by the formation of the hydrogen bonding complexes through the concerted pathway, demonstrating the increase in the reorganization energy by the hydrogen bonding interactions.

To investigate the characteristics of alcohol use among Japanese adults and prevalence of alcohol dependence in Japan, we conducted a nationwide survey on alcohol drinking behavior and alcohol dependence among Japanese adults using a representative sampling method. We sampled 3500 adults from throughout the entire country using a stratified random sampling method with two-step stratification, and carried out a home visit interview survey. A total of 2547 people (72.8%) responded to the survey. The survey period was June, 2003. The questionnaire contained questions about the frequency and quantity of alcohol use, 'hazardous use of alcohol' and 'alcohol dependence' according to the ICD-10 definition, several screening scales on problem use of alcohol (CAGE, KAST, AUDIT), life-time prevalence of 24 alcohol related diseases, smoking status, dysgryphia, and nightcap drinking. The number of respondents was, 1184 males, and 1363 females. Lifetime alcohol drinking, and weekly drinking, and daily drinking rates were 95.1%, 64.4%, and 36.2% for males, 79.0%, 27.5%, and 7.5% for females, respectively. Average daily alcohol consumption was 3.7 units for males, and 2.0 units for females (1 unit = 10 g pure alcohol). The proportion of drinkers who drank alcohol 4 units or more daily was 28.9% for males, and 7.6% for females, and that for 6 units or more was 12.7% for males, and 3.4% for females. The proportion of flasher was 41.2% for males, and 35.0% for females. Among screening questions, problem drinking was most frequently identified using AUDIT (score 12 points or more, 150 persons), followed by KAST (2 points or more, 100 persons) and CAGE (2 points or more, 98 persons). The number of subjects who met the ICD-10 criteria for alcohol dependence was 24, while the number who engaged in hazardous alcohol use was 64. This study revealed that problem drinking and alcohol dependence are a serious problem in Japanese general population. The problem of females drinking may be growing. The government should emphasize the prevention of alcohol drinking problems in adults and continue the conduct of nationwide prevalence surveys to monitor the problem.

Alcoholism is associated with changes in brain reward and control systems, including the prefrontal cortex. In prefrontal areas, the orbitofrontal cortex (OFC) has been suggested to have an important role in the development of alcohol-abuse disorders and studies from this laboratory demonstrate that OFC-mediated behaviors are impaired in alcohol-dependent animals. However, it is not known whether chronic alcohol (ethanol) exposure alters the fundamental properties of OFC neurons. In this study, mice were exposed to repeated cycles of chronic intermittent ethanol (CIE) exposure to induce dependence and whole-cell patch-clamp electrophysiology was used to examine the effects of CIE treatment on lateral OFC (lOFC) neuron excitability, synaptic transmission, and plasticity. Repeated cycles of CIE exposure and withdrawal enhanced current-evoked action potential (AP) spiking and this was accompanied by a reduction in the after-hyperpolarization and a decrease in the functional activity of SK channels. CIE mice also showed an increase in the AMPA/NMDA ratio, and this was associated with an increase in GluA1/GluA2 AMPA receptor expression and a decrease in GluN2B NMDA receptor subunits. Following CIE treatment, lOFC neurons displayed a persistent long-term potentiation of glutamatergic synaptic transmission following a spike-timing-dependent protocol. Lastly, CIE treatment diminished the inhibitory effect of acute ethanol on AP spiking of lOFC neurons and reduced expression of the GlyT1 transporter. Taken together, these results suggest that chronic exposure to ethanol leads to enhanced intrinsic excitability and glutamatergic synaptic signaling of lOFC neurons. These alterations may contribute to the impairment of OFC-dependent behaviors in alcohol-dependent individuals. PMID:26286839

Summary Alcohol abuse and dependence are multifaceted disorders with neurobiological, psychological, and environmental components. Research on other complex neuropsychiatric diseases suggests that genetically influenced intermediate characteristics affect the risk for heavy alcohol consumption and its consequences. Diverse therapeutic interventions can be developed through identification of reliable biomarkers for this disorder and new pharmacological targets for its treatment. Advances in the fields of genomics and proteomics offer a number of possible targets for the development of new therapeutic approaches. This brain-focused review highlights studies identifying neurobiological systems associated with these targets and possible pharmacotherapies, summarizing evidence from clinically relevant animal and human studies, as well as sketching improvements and challenges facing the fields of proteomics and genomics. Concluding thoughts on using results from these profiling technologies for medication development are also presented. PMID:21199775
Delayed matching to sample and concurrent learning in nonamnesic humans with alcohol dependence.

Small samples of alcohol-dependent subjects who showed no clinical signs of Wernicke-Korsakoff syndrome were compared with nonalcohol-dependent controls on two animal memory tests which are performed poorly by human amnesics. Compared to the control subjects, the alcohol-dependent subjects' performance was impaired on a version of the delayed matching to sample task. On concurrent discrimination learning the overall group difference just failed to reach significance. The results are interpreted as suggesting that behavioural impairment may occur in alcohol-dependent subjects who are not clinically amnesic, and that the impairment is similar in type to that observed in cases of severe Wernicke-Korsakoff syndrome.

Chronic alcohol use has widespread effects on brain morphometry. Alcohol dependent individuals are often diagnosed with comorbid substance use disorders. Alterations in brain morphometry may be different in individuals that are dependent on alcohol alone and individuals dependent on alcohol and other substances. We examined subcortical brain volumes in 37 individuals with alcohol dependence only (ADO), 37 individuals with polysubstance use disorder (PS) and 37 healthy control participants (HC). Participants underwent a structural MR scan and a model-based segmentation tool was used to measure the volume of 14 subcortical regions (bilateral thalamus, caudate, putamen, globus pallidus, hippocampus, amygdala and nucleus accumbens). Compared to HC, ADO had smaller volume in the bilateral hippocampus, right nucleus accumbens and right thalamus. PS only had volume reductions in the bilateral thalamus compared to HC. PS had a larger right caudate compared to ADO. Subcortical volume was negatively associated with drinking measures only in the ADO group. This study confirms the association between alcohol dependence and reductions in subcortical brain volume. It also suggests that polysubstance use interacts with alcohol use to produce limited subcortical volume reduction and at least one region of subcortical volume increase. These findings indicate that additional substance use may mask damage through inflammation or may function in a protective manner, shielding subcortical regions from alcohol-induced damage.

Alcohol abuse has deleterious effects on human health by disrupting the functions of many organs and systems. Gut microbiota has been implicated in the pathogenesis of alcohol-related liver diseases, with its composition manifesting expressed dysbiosis in patients suffering from alcoholic dependence. Due to its inherent plasticity, gut microbiota is an important target for prevention and treatment of these diseases. Identification of the impact of alcohol abuse with associated psychiatric symptoms on the gut community structure is confounded by the liver dysfunction. In order to differentiate the effects of these two factors, we conducted a comparative "shotgun" metagenomic survey of 99 patients with the alcohol dependence syndrome represented by two cohorts-with and without liver cirrhosis. The taxonomic and functional composition of the gut microbiota was subjected to a multifactor analysis including comparison with the external control group. Alcoholic dependence and liver cirrhosis were associated with profound shifts in gut community structures and metabolic potential across the patients. The specific effects on species-level community composition were remarkably different between cohorts with and without liver cirrhosis. In both cases, the commensal microbiota was found to be depleted. Alcoholic dependence was inversely associated with the levels of butyrate-producing species from the Clostridiales order, while the cirrhosis-with multiple members of the Bacteroidales order. The opportunist pathogens linked to alcoholic dependence included pro-inflammatory Enterobacteriaceae, while the hallmarks of cirrhosis included an increase of oral microbes in the gut and more frequent occurrence of abnormal community structures. Interestingly, each of the two factors was associated with the expressed enrichment in many Bifidobacterium and Lactobacillus-but the exact set of the species was different between alcoholic dependence and liver cirrhosis. At the level of functional potential, the patients showed different patterns of increase in functions related to alcohol metabolism and virulence factors, as well as pathways related to inflammation. Multiple shifts in the community structure and metabolic potential suggest strong negative influence of alcohol dependence and associated liver dysfunction on gut microbiota. The identified differences in patterns of impact between these two factors are important for planning of personalized treatment and prevention of these pathologies via microbiota modulation. Particularly, the expansion of Bifidobacterium and Lactobacillus suggests that probiotic interventions for patients with alcohol-related disorders using representatives of the same taxa should be considered with caution. Taxonomic and functional analysis shows an increased propensity of the gut microbiota to synthesis of the toxic acetaldehyde, suggesting higher risk of colorectal cancer and other pathologies in alcoholics.

Chronic liver disease with cirrhosis is the 12th leading cause of death in the United States, and alcoholic liver disease accounts for approximately half of all cirrhosis deaths. Chronic alcohol consumption is associated with intestinal bacterial dysbiosis, yet we understand little about the contribution of intestinal fungi, or mycobiota, to alcoholic liver disease. Here we have demonstrated that chronic alcohol administration increases mycobiota populations and translocation of fungal β-glucan into systemic circulation in mice. Treating mice with antifungal agents reduced intestinal fungal overgrowth, decreased β-glucan translocation, and ameliorated ethanol-induced liver disease. Using bone marrow chimeric mice, we found that β-glucan induces liver inflammation via the C-type lectin-like receptor CLEC7A on Kupffer cells and possibly other bone marrow-derived cells. Subsequent increases in IL-1β expression and secretion contributed to hepatocyte damage and promoted development of ethanol-induced liver disease. We observed that alcohol-dependent patients displayed reduced intestinal fungal diversity and Candida overgrowth. Compared with healthy individuals and patients with non-alcohol-related cirrhosis, alcoholic cirrhosis patients had increased systemic exposure and immune response to mycobiota. Moreover, the levels of extraintestinal exposure and immune response correlated with mortality. Thus, chronic alcohol consumption is associated with an altered mycobiota and translocation of fungal products. Manipulating the intestinal mycobiome might be an effective strategy for attenuating alcohol-related liver disease.

Alcohol is the most commonly abused substance among adolescents, promoting the development of substance use disorders and compromised decision-making in adulthood. We have previously demonstrated, with a preclinical model in rodents, that adolescent alcohol use results in adult risk-taking behavior that positively correlates with phasic dopamine transmission in response to risky options, but the underlying mechanisms remain unknown. Here, we show that adolescent alcohol use may produce maladaptive decision-making through a disruption in dopamine network dynamics via increased GABAergic transmission within the ventral tegmental area (VTA). Indeed, we find that increased phasic dopamine signaling after adolescent alcohol use is attributable to a midbrain circuit, including the input from the pedunculopontine tegmentum to the VTA. Moreover, we demonstrate that VTA dopamine neurons from adult rats exhibit enhanced IPSCs after adolescent alcohol exposure corresponding to decreased basal dopamine levels in adulthood that negatively correlate with risk-taking. Building on these findings, we develop a model where increased inhibitory tone on dopamine neurons leads to a persistent decrease in tonic dopamine levels and results in a potentiation of stimulus-evoked phasic dopamine release that may drive risky choice behavior. Based on this model, we take a pharmacological approach to the reversal of risk-taking behavior through normalization of this pattern in dopamine transmission. These results isolate the underlying circuitry involved in alcohol-induced maladaptive decision-making and identify a novel therapeutic target. SIGNIFICANCE STATEMENT One of the primary problems resulting from chronic alcohol use is persistent, maladaptive decision-making that is associated with ongoing addiction vulnerability and relapse. Indeed, studies with the Iowa Gambling Task, a standard measure of risk-based decision-making, have reliably shown that alcohol-dependent individuals make riskier, more maladaptive choices than nondependent individuals, even after periods of prolonged abstinence. Using a preclinical model, in the current work, we identify a selective disruption in dopamine network dynamics that may promote maladaptive decision-making after chronic adolescent alcohol use and demonstrate its pharmacological reversal in adulthood. Together, these results highlight a novel neural mechanism underlying heightened risk-taking behavior in alcohol-dependent individuals and provide a potential therapeutic target for further investigation.

Neurobiological Signatures of Alcohol Dependence Revealed by Protein Profiling
Gorini, Giorgio; Roberts, Amanda J.; Mayfield, R. Dayne
2013-01-01
Alcohol abuse causes dramatic neuroadaptations in the brain, which contribute to tolerance, dependence, and behavioral modifications. Previous proteomic studies in human alcoholics and animal models have identified candidate alcoholism-related proteins. However, recent evidences suggest that alcohol dependence is caused by changes in co-regulation that are invisible to single protein-based analysis. Here, we analyze global proteomics data to integrate differential expression, co-expression networks, and gene annotations to unveil key neurobiological rearrangements associated with the transition to alcohol dependence modeled by a Chronic Intermittent Ethanol (CIE), two-bottle choice (2BC) paradigm. We analyzed cerebral cortices (CTX) and midbrains (MB) from male C57BL/6J mice subjected to a CIE, 2BC paradigm, which induces heavy drinking and represents one of the best available animal models for alcohol dependence and relapse drinking. CIE induced significant changes in protein levels in dependent mice compared with their non-dependent controls. Multiple protein isoforms showed region-specific differential regulation as a result of post-translational modifications. Our integrative analysis identified modules of co-expressed proteins that were highly correlated with CIE treatment. We found that modules most related to the effects of CIE treatment coordinate molecular imbalances in endocytic- and energy-related pathways, with specific proteins involved, such as dynamin-1. The qRT-PCR experiments validated both differential and co-expression analyses, and the correspondence among our data and previous genomic and proteomic studies in humans and rodents substantiates our findings. The changes identified above may play a key role in the escalation of ethanol consumption associated with dependence. Our approach to alcohol addiction will advance knowledge of brain remodeling mechanisms and adaptive changes in response to drug abuse, contribute to understanding of organizational principles of CTX and MB proteomes, and define potential new molecular targets for treating alcohol addiction. The integrative analysis employed here highlight the advantages of systems approaches in studying the neurobiology of alcohol addiction. PMID:24358215

The prevalence of female alcohol and substance abusers has markedly increased. The main objective of this research was to explore personality profiles among females who had alcohol and opiate dependence. The aim of the study is to analyse if there is differences in personality profiles of females addicted to alcohol and opiates. We hypothesized that there might be significant differences in personality profiles among subgroups of women who present with alcohol and opiate use disorders. Of 157 consecutive women with diagnosis of alcohol/opiate addiction, 62 fulfilled following inclusion criteria: age 19-45 years, abstinence from alcohol and opiates for at least 10 days prior to enrollment. Alcohol-dependent group consisted of 30 females, while opiate-dependent group consisted of 32 females. The control group involved 30 age-matched randomly chosen healthy women. The data were collected using the Revised NEO Personality Inventory (NEO-PI-R). The multiple stepwise discriminant analysis was used to determine relations between personality traits and the probability of belonging to one of the study groups. Significant differences in the NEO-PI-R scores were observed between groups for all main personality traits except for Openness to Experience. Compared with controls, substance-dependent women scored significantly higher on Neuroticism and lower on Conscientiousness. Opiate-dependent females scored the highest on Neuroticism and on Extraversion and lowest on Agreeableness and on Conscientiousness. Alcohol-dependent females scored higher on Conscientiousness and lower on Neuroticism compared to opiate-dependent women. The results of our study confirmed significant characteristics in personality profiles among females with alcohol and opiate dependence, as well as the difference between these two groups of substance abusers and their healthy controls. The distinct personality characteristics among different groups of substance addicted women should be taken into account when creating the most effective program of prevention and therapeutic approaches in this specific cohort.

Key points Chronic alcohol consumption causes a spectrum of liver diseases, but the pathogenic mechanisms driving the onset and progression of disease are not clearly defined.We show that chronic alcohol feeding sensitizes rat hepatocytes to Ca2+‐mobilizing hormones resulting in a leftward shift in the concentration–response relationship and the transition from oscillatory to more sustained and prolonged Ca2+ increases.Our data demonstrate that alcohol‐dependent adaptation in the Ca2+ signalling pathway occurs at the level of hormone‐induced inositol 1,4,5 trisphosphate (IP3) production and does not involve changes in the sensitivity of the IP3 receptor or size of internal Ca2+ stores.We suggest that prolonged and aberrant hormone‐evoked Ca2+ increases may stimulate the production of mitochondrial reactive oxygen species and contribute to alcohol‐induced hepatocyte injury. Abstract ‘Adaptive’ responses of the liver to chronic alcohol consumption may underlie the development of cell and tissue injury. Alcohol administration can perturb multiple signalling pathways including phosphoinositide‐dependent cytosolic calcium ([Ca2+]i) increases, which can adversely affect mitochondrial Ca2+ levels, reactive oxygen species production and energy metabolism. Our data indicate that chronic alcohol feeding induces a leftward shift in the dose–response for Ca2+‐mobilizing hormones resulting in more sustained and prolonged [Ca2+]i increases in both cultured hepatocytes and hepatocytes within the intact perfused liver. Ca2+ increases were initiated at lower hormone concentrations, and intercellular calcium wave propagation rates were faster in alcoholics compared to controls. Acute alcohol treatment (25 mm) completely inhibited hormone‐induced calcium increases in control livers, but not after chronic alcohol‐feeding, suggesting desensitization to the inhibitory actions of ethanol. Hormone‐induced inositol 1,4,5 trisphosphate (IP3) accumulation and phospholipase C (PLC) activity were significantly potentiated in hepatocytes from alcohol‐fed rats compared to controls. Removal of extracellular calcium, or chelation of intracellular calcium did not normalize the differences in hormone‐stimulated PLC activity, indicating calcium‐dependent PLCs are not upregulated by alcohol. We propose that the liver ‘adapts’ to chronic alcohol exposure by increasing hormone‐dependent IP3 formation, leading to aberrant calcium increases, which may contribute to hepatocyte injury.

Abstract Background and aims Nalmefene has been approved in Europe for the treatment of alcohol dependence and subsequently recommended by the UK National Institute for Health and Care Excellence (NICE). This study examines critically the evidence base underpinning both decisions and the issues arising. Methods Published studies of nalmefene were identified through a systematic search, with documents from the European Medicines Agency, the NICE appraisal and public clinical trial registries also examined to identify methodological issues. Results Efficacy data used to support the licensing of nalmefene suffer from risk of bias due to lack of specification of a priori outcome measures and sensitivity analyses, use of post‐hoc sample refinement and the use of inappropriate comparators. Despite this, evidence for the efficacy of nalmefene in reducing alcohol consumption in those with alcohol dependence is, at best, modest, and of uncertain significance to individual patients. The relevance of existing trial data to routine primary care practice is doubtful. Conclusions Problems with the registration, design, analysis and reporting of clinical trials of nalmefene did not prevent it being licensed and recommended for treating alcohol dependence. This creates dilemmas for primary care clinicians and commissioning organisations where nalmefene has been heavily promoted, and poses wider questions about the effectiveness of the medicines regulation system and how to develop the alcohol treatment evidence base.

The genes encoding the gamma-aminobutyric acid(A) (GABA(A)) receptor have been the focus of several recent studies investigating the genetic etiology of alcohol dependence. Analyses of multiplex families found a particular gene, GABRA2, to be highly associated with alcohol dependence, using within-family association tests and other methods. Results were confirmed in three case-control studies. The objective of this study was to investigate the GABRA2 gene in another collection of multiplex families. Analyses were based on phenotypic and genotypic data available for 330 individuals from 65 bigenerational pedigrees with a total of 232 alcohol-dependent subjects. A proband pair of same-sex siblings meeting Diagnostic and Statistical Manual of Mental Disorders, Third Edition, criteria for alcohol dependence was required for entry of a family into the study. One member of the proband pair was identified while in treatment for alcohol dependence. Linkage and association of GABRA2 and alcohol dependence were evaluated using SIBPAL (a nonparametric linkage package) and both the Pedigree Disequilibrium Test and the Family-Based Association Test, respectively. We find no evidence of a relationship between GABRA2 and alcohol dependence. Linkage analyses exhibited no linkage using affected/affected, affected/unaffected, and unaffected/unaffected sib pairs (all p's < .13). There was no evidence of a within-family association (all p's > .39). Comorbidity may explain why our results differ from those in the literature. The presence of primary drug dependence and/or other psychiatric disorders is minimal in our pedigrees, although several of the other previously published multiplex family analyses exhibit a greater degree of comorbidity.

Objective: The aim of this study was to examine psychometric properties of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), diagnostics criteria for alcohol and marijuana dependences among 462 alcohol users and 311 marijuana users enrolled in two multisite trials of the National Drug Abuse Treatment Clinical Trials Network. Method: Diagnostic questions were assessed by the DSM-IV checklist. Data were analyzed by the item response theory and the multiple indicators–multiple causes method procedures. Results: Criterion symptoms of alcohol and marijuana dependences exhibited a high level of internal consistency. All individual symptoms showed good discrimination in distinguishing alcohol or marijuana users between high and low severity levels of the continuum. In both groups, “withdrawal” appeared to measure the most severe symptom of the dependence continuum. There was little evidence of measurement nonequivalence in assessing symptoms of dependence by gender, age, race/ethnicity, and educational level. Conclusions: These findings highlight the clinical utility of the DSM-IV checklist in assessing alcohol- and marijuana-dependence syndromes among treatment-seeking substance users. PMID:19371493

Given the clinical and public health significance of substance disorders and the need to identify their early risk factors, we examined the association of childhood attention-deficit/hyperactivity disorder (ADHD) with substance use (e.g., nicotine, alcohol) and abuse/dependence outcomes (nicotine, alcohol, marijuana, cocaine, other). To strengthen a potential causal inference, we meta-analyzed longitudinal studies that prospectively followed children with and without ADHD into adolescence or adulthood. Children with ADHD were significantly more likely to have ever used nicotine and other substances, but not alcohol. Children with ADHD were also more likely to develop disorders of abuse/dependence for nicotine, alcohol, marijuana, cocaine, and other substances (i.e., unspecified). Sex, age, race, publication year, sample source, and version of the Diagnostic and Statistical Manual of Mental Disorders (DSM) used to diagnose ADHD did not significantly moderate the associations with substance outcomes that yielded heterogeneous effect sizes. These findings suggest that children with ADHD are significantly more likely to develop substance use disorders than children without ADHD and that this increased risk is robust to demographic and methodological differences that varied across the studies. Finally, few studies addressed ADHD and comorbid disruptive behavior disorders (DBD), thus preventing a formal meta-analytic review. However, we qualitatively summarize the results of these studies and conclude that comorbid DBD complicates inferences about the specificity of ADHD effects on substance use outcomes. PMID:21382538

Unhealthy alcohol use, highly prevalent in the Russian Federation (Russia), is associated with HIV risk behaviors among people living with HIV (PLWH). HIV stigma contributes to the HIV risk environment in Russia. To examine HIV stigma among Russian PLWH and to explore its association with unhealthy alcohol use, we conducted a longitudinal analysis of 700 PLWH in St. Petersburg, Russia. We assessed the association between alcohol dependence and HIV stigma measured at baseline and 12 months follow-up. Participants with alcohol dependence (n = 446) reported significantly higher HIV stigma scores over time than those without dependence (n = 254) (adjusted mean difference 0.60, 95% CI 0.03–1.17; p = 0.04). In secondary analyses, we examined recent risky alcohol use and did not detect an association with HIV stigma. Alcohol dependence is associated with high HIV stigma among Russian PLWH but the nature of the association is conjectural. HIV prevention efforts in Russia that address alcohol use disorders hold potential to mitigate HIV-related stigma and its possible adverse effects among PLWH. PMID:28600603

Alcohol-dependent individuals (ALC) simultaneously present decreased inhibitory control and increased attention towards alcohol-related cues. The dual-process models have proposed that these symptoms reflect an imbalance between prefrontal/reflective and limbic/automatic systems, respectively leading to cognitive dysfunctions in executive processes and to alcohol-related bias. However, most previous research has focused on a separate exploration of these systems among ALC, and the direct measure of their interactions remains to be conducted. Moreover, no study has explored the evolution of this imbalance across the successive stages of alcohol-related disorders, and particularly in Korsakoff syndrome (KS), the most frequent neurological complication of alcohol-dependence. Ten KS, 14 ALC, and 14 matched control participants performed a modified Flanker task, the "Alcohol Flanker Task," based on congruent, incongruent, and neutral conditions with alcohol-related stimuli. This task required inhibitory processing on alcohol-related stimuli and evaluated, through a behavioral approach, the interaction between reflective and automatic systems, as well as its evolution between ALC and KS. ALC and KS both presented high reactivity towards alcohol-related stimuli, confirming the presence of alcohol-related bias. KS showed increased omission rates (related to distractor interference) while ALC showed higher false-alarm rates (related to prepotent response inhibition). These results suggest that different inhibitory subcomponents might be altered at the successive stages of the pathology, and experimentally confirms the crucial role of the interaction between reflective and automatic processes in alcohol-use disorders. The present results reinforce the proposal that alcohol-related cues significantly impact inhibitory control in alcohol-related disorders. However, ALC and KS present different patterns of deficits depending on task complexity (i.e., executive load), thus suggesting a dissociation in inhibitory functions when processing alcohol-related cues.

This study was conducted to assess the interaction between alcohol cues and social pressure in the induction of alcohol craving. Fourteen male patients with alcohol dependence and 14 age-matched social drinkers completed a virtual reality coping skill training program composed of four blocks according to the presence of alcohol cues (x2) and social pressure (x2). Before and after each block, the craving levels were measured using a visual analogue scale. Patients with alcohol dependence reported extremely high levels of craving immediately upon exposure to a virtual environment with alcohol cues, regardless of social pressure. In contrast, the craving levels of social drinkers were influenced by social pressure from virtual avatars. Our findings imply that an alcohol cue-laden environment should interfere with the ability to use coping skills against social pressure in real-life situations.

The purpose of the study was to examine whether caffeine dependence and a family history of alcoholism are associated with continued use of caffeine during pregnancy. Forty-four women seeking obstetrical care in an office-based practice completed questionnaires and provided saliva samples at three prenatal visits occurring 2-3, 3-4, and 7 months postconception. On visit 1, the patients received the physician's instructions to stop using caffeine. Structured interviews were used to assign a diagnosis of caffeine dependence (lifetime) and to identify family history of alcoholism. Outcome measures included self-reported levels of caffeine use and saliva caffeine levels at the three prenatal visits. Although most women eliminated or substantially reduced their caffeine consumption between pregnancy awareness and prenatal visit 1, those with a lifetime diagnosis of caffeine dependence and a family history of alcoholism had higher levels of caffeine use and lower rates of abstinence throughout pregnancy. Saliva caffeine levels confirmed these effects. Withdrawal symptoms, functional impairment, and craving were cited as reasons they failed to eliminate or cut back on caffeine use. Fifty percent of the women with both a lifetime diagnosis of caffeine dependence and a family history of alcoholism continued to use caffeine in amounts (>300 mg/day) greater than those considered safe during pregnancy, compared to none of the women without caffeine dependence and a family history of alcoholism. Women with a lifetime diagnosis of caffeine dependence and a family history of alcoholism also reported higher rates of past cigarette smoking and problematic alcohol use. Caffeine-dependent women with a family history of alcoholism were not able to follow their physician's advice to reduce or eliminate caffeine consumption during pregnancy, despite their wanting to do so. This subgroup may require more intensive intervention to ensure caffeine abstinence and may be at greater risk for abuse of or dependence on other drugs.

Drug addiction and alcoholism involve a complex etiopathogenesis with a variable degree of risk contributions from the host (person), environment, and addictive substances. In this work, temperament and character features of individuals addicted to opiates or alcohol are compared with normal controls to study personality factors in the overall risk for drug addiction. The study was done in a permissive environment, with easy access to alcohol and heroin, which facilitated analyses of personality factors in drug choice. Participants included 412 consecutive patients (312 opiate addicts, 100 alcohol addicts) treated at the Specialized Hospital for Chemical Dependency in Belgrade, Serbia, and a community sample of 346 controls. Opiate addicts manifested antisocial temperament configuration (high Novelty Seeking, low Reward Dependence) coupled with high Self-transcendence (ie, susceptibility to fantasy and imagination). Alcohol addicts manifested sensitive temperament configuration (high Novelty Seeking coexisting with high Harm Avoidance). Immature personality was observed far more frequently in opiate addicts than in alcoholics or normals. Novelty Seeking appears to be a general risk factor for drug addiction. High Harm Avoidance appears to channel individuals with high Novelty Seeking towards alcoholism. Immature character traits and probable Personality Disorder increase the risk of illegal drugs. Based on equivalent research in nonpermissive environments, at least a portion of our opiate addicts could have developed alcoholism instead in environments with more limited access to opiates. Personality factors provide useful guidelines for preventive work with young individuals with personality risk factors for drug addiction. Copyright © American Academy of Addiction Psychiatry.

Literature reports particularities in certain psychological dimensions, such as personality traits, early maladaptive schemas and attachment styles among patients dependent on alcohol. Several international studies have also emphasized significant gender differences in psychological profiles. However, in France, only a few studies have dealt with this subject. Our aim was on the one hand to study the characteristics of alcohol-dependent patients in these variables, and on the other hand to search for gender differences. The personality dimensions were assessed with the French Big Five Inventory (Fr-BFI), the attachment style with Bartholomew's Relationship Scales Questionnaire (RSQ), and early maladaptive schemas with the short version of Young's questionnaire (YSQ-S1). Seventy-three subjects were included: 39 alcohol-dependent patients (19 men and 20 women) and 34 healthy control subjects (17 men and 17 women). The scores of alcohol-dependent patients were compared with those of a healthy control group (n=34, 17 men, 17 women) and available standards. We also compared the scores of men and women with alcohol dependence between them, and we compared the scores of men and women to those of the control group and those of the reference sample of the same sex. This is an ongoing study and we publish here the first results. Compared with control subjects, and the reference sample, alcohol-dependent patients showed significantly higher levels of neuroticism and lower levels of extraversion. Furthermore, differences in attachment styles were observed compared to the control group: alcohol-dependent patients presented a less secure attachment, seemed more fearful and detached, but the results remained within the normal standards. Compared to the control subjects, alcohol-dependent patients showed a significant increase in scores regarding many schemas: emotional deprivation, abandonment, abuse/mistrust, isolation, imperfection, dependence, symbiotic relationship, subjugation, and emotional inhibition. Men and women with alcohol dependence did not show a significant difference between them concerning the dimensions of personality, the schemas, and attachment styles. In addition, the comparison of each sub-group (male/female) with the control group of the same sex and standards available showed specific features: for dimensions of personality, alcohol-dependent men presented a high level of neuroticism and a low level of extraversion, while the women showed no specific features. Concerning attachment, both men and women differed from the control group. Their attachment was more fearful and men showed a less secure and more detached attachment. As for patterns, three are higher among men and women with alcohol dependence compared to controls of the same sex: emotional deprivation, abuse/mistrust, and imperfection. In addition, these schemas seem to be more specific according to gender: alcoholic women differed from controls of the same sex at the subjugation schema, which was not the case for men, while only men differed from men of the control group by higher scores in insufficient self-control, dependency and symbiotic relationship. This study shows not only particularities in patients with alcohol dependence concerning personality dimensions, styles of attachment and early maladaptive schemas, but also gender differences when comparing each subgroup (men and women) with controls of the same sex. Even if these results need to be confirmed by using a larger sample, the particularities deserve consideration, especially gender differences in view of appropriate psychotherapeutic strategies.

Background Identifying factors that modify responsiveness to pharmacotherapies for alcohol dependence is important for treatment planning. Cigarette smoking predicts more severe alcohol dependence and poorer treatment response in general. Nevertheless, there is limited research on cigarette smoking as a potential predictor of differential response to pharmacological treatment of alcoholism. Methods We examined the association between cigarette smoking and drinking outcomes in the COMBINE study, a randomized, double-blind placebo-controlled 16-week trial comparing combinations of medications (i.e., acamprosate and naltrexone) and behavioral interventions (i.e., medical management (MM), combined behavioral therapy (CBI)) in 1383 alcohol dependent individuals. Results Smokers (i.e., more than half the sample) significantly differed from nonsmokers on several demographic and drinking-related variables at baseline and generally had poorer treatment outcomes than nonsmokers. However, smokers who received naltrexone had better drinking outcomes than smokers who received placebo, whereas alcohol use among nonsmokers did not vary by naltrexone assignment. This pattern of findings occurred independent of whether patients received CBI or MM and remained after controlling for alcoholism typology and baseline demographic differences. Approximately 9% of smokers quit smoking and an additional 10% reduced their cigarette intake during treatment. Reductions in smoking did not vary by treatment assignment. Conclusions These results suggest that naltrexone may be particularly beneficial for improving alcohol use outcomes in alcohol dependent smokers.

Neuropsychological studies have shown that alcohol dependence is associated with neurocognitive deficits in tasks requiring memory, perceptual motor skills, abstraction and problem solving, whereas language skills are relatively spared in alcoholics despite structural abnormalities in the language-related brain regions. To investigate the preserved mechanisms of language processing in alcohol-dependents, functional brain imaging was undertaken in healthy controls (n=18) and alcohol-dependents (n=16) while completing a lexical semantic judgment task in a 3 T MR scanner. Behavioural data indicated that alcohol-dependents took more time than controls for performing the task but there was no significant difference in their response accuracy. fMRI data analysis revealed that while performing the task, the alcoholics showed enhanced activations in left supramarginal gyrus, precuneus bilaterally, left angular gyrus, and left middle temporal gyrus as compared to control subjects. The extensive activations observed in alcoholics as compared to controls suggest that alcoholics recruit additional brain areas to meet the behavioural demands for equivalent task performance. The results are consistent with previous fMRI studies suggesting compensatory mechanisms for the execution of task for showing an equivalent performance or decreased neural efficiency of relevant brain networks. However, on direct comparison of the two groups, the results did not survive correction for multiple comparisons; therefore, the present findings need further exploration.

Aims To describe alcohol consumption behavior of male Latino migrant farmworkers, compare their alcohol consumption behavior with that of other male Latino immigrants, and determine factors associated with risk for alcohol dependence among Latino immigrant workers. Methods Cross-sectional data were drawn from baseline interviews conducted as part of a larger community-based participatory research project examining the cognitive and neurological outcomes of pesticide exposure. A total of 235 farmworkers and 212 non-farmworkers completed interviews between May and August, 2012. Results Although 17.5% of the North Carolina Latino farmworkers report never having drunk alcohol, and a total of 34.5% report not having drunk alcohol in the previous three months, 48.5% engaged in heavy episodic drinking (HED) in the previous 3 months, and 23.8% frequently engaged in HED during this period. Farmworkers and non-farmworkers did not differ significantly in alcohol consumption behavior. Farmworkers and non-farmworkers did differ significantly in each component of the CAGE scale, with 37.9% of farmworkers and 16.0% of non-farmworkers being at risk for alcohol dependence (p<0.0001). Significant factors for being at risk for alcohol dependence were stress (Odds Ratio 1.06, 95% Confidence Interval 1.03, 1.09) and being a farmworker (Odds Ratio 3.58, 95% Confidence Interval 2.12, 6.06). Being married reduced the risk of alcohol dependence (Odds Ratio 0.45, 95% Confidence Interval 0.39, 0.87). Conclusions Latino farmworkers and non-farmworkers consume relatively large amounts of alcohol and engage in heavy episodic drinking at relatively high rates. Latino farmworkers have very high rates of risk for alcohol dependence. Policy changes and public health interventions are needed to address these concerns for a population that is vital to the agricultural economy. PMID:26842256

We have used a translational Convergent Functional Genomics (CFG) approach to discover genes involved in alcoholism, by gene-level integration of genome-wide association study (GWAS) data from a German alcohol dependence cohort with other genetic and gene expression data, from human and animal model studies, similar to our previous work in bipolar disorder and schizophrenia. A panel of all the nominally significant P-value SNPs in the top candidate genes discovered by CFG (n=135 genes, 713 SNPs) was used to generate a genetic risk prediction score (GRPS), which showed a trend towards significance (P=0.053) in separating alcohol dependent individuals from controls in an independent German test cohort. We then validated and prioritized our top findings from this discovery work, and subsequently tested them in three independent cohorts, from two continents. A panel of all the nominally significant P-value single-nucleotide length polymorphisms (SNPs) in the top candidate genes discovered by CFG (n=135 genes, 713 SNPs) were used to generate a Genetic Risk Prediction Score (GRPS), which showed a trend towards significance (P=0.053) in separating alcohol-dependent individuals from controls in an independent German test cohort. In order to validate and prioritize the key genes that drive behavior without some of the pleiotropic environmental confounds present in humans, we used a stress-reactive animal model of alcoholism developed by our group, the D-box binding protein (DBP) knockout mouse, consistent with the surfeit of stress theory of addiction proposed by Koob and colleagues. A much smaller panel (n=11 genes, 66 SNPs) of the top CFG-discovered genes for alcoholism, cross-validated and prioritized by this stress-reactive animal model showed better predictive ability in the independent German test cohort (P=0.041). The top CFG scoring gene for alcoholism from the initial discovery step, synuclein alpha (SNCA) remained the top gene after the stress-reactive animal model cross-validation. We also tested this small panel of genes in two other independent test cohorts from the United States, one with alcohol dependence (P=0.00012) and one with alcohol abuse (a less severe form of alcoholism; P=0.0094). SNCA by itself was able to separate alcoholics from controls in the alcohol-dependent cohort (P=0.000013) and the alcohol abuse cohort (P=0.023). So did eight other genes from the panel of 11 genes taken individually, albeit to a lesser extent and/or less broadly across cohorts. SNCA, GRM3 and MBP survived strict Bonferroni correction for multiple comparisons. Taken together, these results suggest that our stress-reactive DBP animal model helped to validate and prioritize from the CFG-discovered genes some of the key behaviorally relevant genes for alcoholism. These genes fall into a series of biological pathways involved in signal transduction, transmission of nerve impulse (including myelination) and cocaine addiction. Overall, our work provides leads towards a better understanding of illness, diagnostics and therapeutics, including treatment with omega-3 fatty acids. We also examined the overlap between the top candidate genes for alcoholism from this work and the top candidate genes for bipolar disorder, schizophrenia, anxiety from previous CFG analyses conducted by us, as well as cross-tested genetic risk predictions. This revealed the significant genetic overlap with other major psychiatric disorder domains, providing a basis for comorbidity and dual diagnosis, and placing alcohol use in the broader context of modulating the mental landscape.

Item response theory (IRT) was used to determine whether the DSM-IV diagnostic criteria for alcohol abuse and dependence are arrayed along a continuum of severity. Data came from a large nationally representative sample of the US population, 18 years and older. A two-parameter logistic IRT model was used to determine the severity and discrimination of each DSM-IV criterion. Differential criterion functioning (DCF) was also assessed across subgroups of the population defined by sex, age and race-ethnicity. All DSM-IV alcohol abuse and dependence criteria, except alcohol-related legal problems, formed a continuum of alcohol use disorder severity. Abuse and dependence criteria did not consistently tap the mildest or more severe end of the continuum respectively, and several criteria were identified as potentially redundant. The drinking in larger amounts or for longer than intended dependence criterion had the greatest discrimination and lowest severity than any other criterion. Although several criteria were found to function differentially between subgroups defined in terms of sex and age, there was evidence that the generalizability and validity of the criterion forming the continuum remained intact at the test score level. DSM-IV diagnostic criteria for alcohol abuse and dependence form a continuum of severity, calling into question the abuse-dependence distinction in the DSM-IV and the interpretation of abuse as a milder disorder than dependence. The criteria tapped the more severe end of the alcohol use disorder continuum, highlighting the need to identify other criteria capturing the mild to intermediate range of the severity. The drinking larger amounts or longer than intended dependence criterion may be a bridging criterion between drinking patterns that incur risk of alcohol use disorder at the milder end of the continuum, with tolerance, withdrawal, impaired control and serious social and occupational dysfunction at the more severe end of the alcohol use disorder continuum. Future IRT and other dimensional analyses hold great promise in informing revisions to categorical classifications and constructing new dimensional classifications of alcohol use disorders based on the DSM and the ICD.

Excessive alcohol use among the homeless may contribute to their high rates of emergency department use. Survey-based studies have provided some information on the relation between alcohol and emergency department use among the homeless. This study used an intensive schedule of random breath collections and self-report assessments to examine the relation between emergency department utilization and alcohol use in homeless alcohol-dependent adults. Data were from homeless alcohol-dependent adults (N=116) who were participating in a therapeutic workplace that provided job-skills training every weekday for 26 weeks. Breath-sample collections and assessments of self-reported alcohol use were scheduled each week, an average of twice per week per participant, at random times between 9:00 A.M. and 5:00 P.M. Participants received $35 for each breath sample collected. Self-reports of emergency department use were assessed throughout the study. Thirty-four percent of participants reported attending an emergency department and reported an average of 2.2 emergency department visits (range 1-10 visits). Alcohol intoxication was the most common reason for emergency department use. Participants who used the emergency department had significantly more alcohol-positive breath samples and more self-reported heavy alcohol use than participants who did not use the emergency department. This study provided a rare intensive assessment of alcohol and emergency department use in homeless alcohol-dependent adults over an extended period. Emergency department use was high and was significantly related to indices of alcohol use. Copyright © 2017 Elsevier B.V. All rights reserved.

Objective The ratio of 2nd to 4th digit length (2D:4D) is a sexually dimorphic trait. Men have a relatively shorter second digit than fourth digit. This ratio is thought to be influenced by higher prenatal testosterone level or greater sensitivity to androgen. The purpose of this study is to investigate the relationship between alcohol dependence and 2D:4D in a Korean sample and whether 2D:4D can be a biologic marker in alcohol dependence. Methods In this study, we recruited 87 male patients with alcohol dependence from the alcohol center of one psychiatric hospital and 52 healthy male volunteers who were all employees in the same hospital as controls. We captured images of the right and left hands of patients and controls using a scanner and extracted data with a graphics program. We measured the 2D:4D of each hand and compared the alcohol dependence group with the control group. We analyzed these ratios using an independent-samples t-test. Results The mean 2D:4D of patients was 0.934 (right hand) and 0.942 (left hand), while the mean 2D:4D of controls was 0.956 (right hand) and 0.958 (left hand). Values for both hands were significantly lower for patients than controls (p<0.001, right hand; p=0.004, left hand). Conclusion Patients who are alcohol dependent have a significantly lower 2D:4D than controls, similar to the results of previous studies, which suggest that a higher prenatal testosterone level in the gonadal period is related to alcoholism. Furthermore, 2D:4D is a possible predictive marker of alcohol dependence. PMID:27121425

Values for both hands were significantly lower for patients than controls (p<0.001, right hand; p=0.004, left hand). Patients who are alcohol dependent have a significantly lower 2D:4D than controls, similar to the results of previous studies, which suggest that a higher prenatal testosterone level in the gonadal period is related to alcoholism. Furthermore, 2D:4D is a possible predictive marker of alcohol dependence.
Epigenetics—Beyond the Genome in Alcoholism

Genetic and environmental factors play a role in the development of alcoholism. Whole-genome expression profiling has highlighted the importance of several genes that may contribute to alcohol abuse disorders. In addition, more recent findings have added yet another layer of complexity to the overall molecular mechanisms involved in a predisposition to alcoholism and addiction by demonstrating that processes related to genetic factors that do not manifest as DNA sequence changes (i.e., epigenetic processes) play a role. Both acute and chronic ethanol exposure can alter gene expression levels in specific neuronal circuits that govern the behavioral consequences related to tolerance and dependence. The unremitting cycle of alcohol consumption often includes satiation and self-medication with alcohol, followed by excruciating withdrawal symptoms and the resultant relapse, which reflects both the positive and negative affective states of alcohol addiction. Recent studies have indicated that behavioral changes induced by acute and chronic ethanol exposure may involve chromatin remodeling resulting from covalent histone modifications and DNA methylation in the neuronal circuits involving a brain region called the amygdala. These findings have helped identify enzymes involved in epigenetic mechanisms, such as the histone deacetylase, histone acetyltransferase, and DNA methyltransferase enzymes, as novel therapeutic targets for the development of future pharmacotherapies for the treatment of alcoholism.

Despite claims that comorbid anxiety disorders tend to lead to a poor outcome in the treatment of alcohol dependence, the few studies on this topic show conflicting results. To test whether the outcome of treatment-seeking alcohol-dependent patients with a comorbid phobic disorder is worse than that of similar patients without a comorbid phobic disorder. The probabilities of starting to drink again and of relapsing into regular heavy drinking in (i) a group of 81 alcohol-dependent patients with comorbid social phobia or agoraphobia were compared with those in (ii) a group of 88 alcohol-dependent patients without anxiety disorders in a naturalistic follow-up using Cox regression analysis. Adjusted for initial group differences, the hazard ratio for the association of phobic disorders with resumption of drinking was 1.05 (95% CI, 0.85-1.30, P = 0.66) and the adjusted hazard ratio for the association of phobic disorders with a relapse into regular heavy drinking was 1.02 (95% CI, 0.78-1.33, P = 0.89). The findings of this study do not confirm the idea that alcohol-dependent patients who have undergone alcohol-dependence treatment are at greater risk of a relapse if they have a comorbid anxiety disorder. No differences were found in abstinence duration or time to relapse into regular heavy drinking between patients with and without comorbid phobic disorders.
Prone to feel guilty: Self-evaluative emotions in alcohol-dependence.

Prior research has repeatedly shown that alcohol-dependence is associated with interpersonal difficulties. However, guilt and shame, two crucial self-evaluative emotions triggered by the transgression of social norms, have not been explored among alcohol-dependent individuals despite their important role in psychiatric disorders. The present study thus aimed to investigate whether alcohol-dependence is associated with greater proneness to negatively evaluate one's own behaviors (guilt) or the entire self (shame). 25 alcohol-dependent individuals (ADI) and 25 matched healthy individuals completed a scenario-based inventory (TOSCA-3), requiring from participants to rate the extent they will react to each scenario in terms of (contextualized) guilt and shame. Participants also completed a list of adjectives related to the frequency at which they generally experience (uncontextualized) guilt and shame (PFQ-2). When controlling for possible confounds (i.e., depression and anxiety), ADI reported greater proneness to experience guilt at the TOSCA-3 (η 2 =.22) compared to healthy individuals. This study is the first to show that alcohol-dependence is associated with greater contextualized guilt-proneness, i.e., negative evaluation of one's own behaviors that transgress social norms. Therefore, these results reinforce the relevance of social disorders in alcohol-dependence and indicate that ADI may benefit of therapeutic programs to avoid a generalization of guilt towards shame.

Fatty liver is an important clinical feature not only in alcoholic and non-alcoholic fatty liver diseases, but in other chronic liver diseases as well. Our aim was to elucidate the effect and relationship between habitual alcohol intake and obesity in the development of fatty liver disease. We enrolled 8,029 subjects undergoing abdominal ultrasonography with general medical examinations, and analyzed the factors associated with fatty liver based on daily alcohol intake, body mass index (BMI), and waist circumference. For fatty liver, BMI, waist circumference, total cholesterol, triglycerides, and fasting plasma glucose were significant and independent risk factors. Heavy alcohol intake (50 g/day) was a significant risk factor for fatty liver in women (odds ratio [OR], 3.35). Analysis based on the presence or absence of obesity revealed that moderate alcohol intake was a significant negative risk factor for fatty liver in both male and female obese (BMI ≥25 kg/m(2)) subjects (OR, 0.74 for non-obese and 0.39 for obese patients, respectively). Heavy alcohol intake was also a significant negative risk factor in obese males (0.62). In contrast, heavy alcohol intake was a risk factor in non-obese males (OR, 1.29) and in all females (OR, 2.22 for non-obese and 6.6 for obese patients, respectively). The influence of alcohol intake on fatty liver differed depending on the level of alcohol consumption, gender, and the presence of obesity, and showed biphasic effects.

Some salivary markers of alcohol abuse/dependence have been proposed so far: aminotransferases, gamma-glutamyltransferase, ethanol, ethyl glucuronide, ethyl sulfate, sialic acid, β-hexosaminidase A, oral peroxidase, methanol, diethylene/ethylene glycol, α-amylase, clusterin, haptoglobin, heavy/light chains of immunoglobulins and transferrin. To investigate the effect of chronic alcohol drinking and smoking on the activity (pKat/ml) and output (pKat/min) of salivary lysosomal exoglycosidases: α-fucosidase (FUC), α-mannosidase (MAN), β-galactosidase (GAL), and β-glucuronidase (GLU), and their applicability as markers of alcohol dependence. The activity of FUC, MAN, GAL and GLU was measured colorimetrically in the saliva of healthy social drinkers, alcohol-dependent non-smokers and alcohol-dependent smokers. We observed an increased salivary activity of FUC, GAL, GLU and MAN, as well as an increased output of GAL and GLU, in comparison with controls. The highest increase in the activity/output was found in salivary GLU and MAN (GLU, even 7- to 18-fold), and the least in GAL. We found an excellent sensitivity and specificity and a high accuracy (measured by the area under the ROC curve) for salivary FUC, GLU and MAN activities. The salivary GLU activity positively correlated with the number of days of last alcohol intoxication. Salivary activity of FUC, GAL and MAN, but not GLU, positively correlated with the periodontal parameters such as gingival index and papilla bleeding index. Although we found an excellent sensitivity and specificity as well as a high accuracy for the salivary activity of FUC, GLU and MAN, the GLU activity seems to be mostly applicable as a marker of chronic alcohol drinking (alcohol dependence). © The Author 2014.

Contemporary research has shown that a high number of alcohol-dependent and other drug-dependent individuals have a sweet preference, specifically for foods with a high sucrose concentration. Moreover, both human and animal studies have demonstrated that in some brains the consumption of sugar-rich foods or drinks primes the release of euphoric endorphins and dopamine within the nucleus accumbens, in a manner similar to some drugs of abuse. The neurobiological pathways of drug and "sugar addiction" involve similar neural receptors, neurotransmitters, and hedonic regions in the brain. Craving, tolerance, withdrawal and sensitization have been documented in both human and animal studies. In addition, there appears to be cross sensitization between sugar addiction and narcotic dependence in some individuals. It has also been observed that the biological children of alcoholic parents, particularly alcoholic fathers, are at greater risk to have a strong sweet preference, and this may manifest in some with an eating disorder. In the last two decades research has noted that specific genes may underlie the sweet preference in alcohol- and drug-dependent individuals, as well as in biological children of paternal alcoholics. There also appears to be some common genetic markers between alcohol dependence, bulimia, and obesity, such as the A1 allele gene and the dopamine 2 receptor gene.

Basic experiments support the impact of hypocretin on hyperarousal and motivated state required for increasing drug craving. Our aim was to assess the frequencies of smoking, alcohol and drug use, abuse and dependence in narcolepsy type 1 (NT1, hypocretin-deficient), narcolepsy type 2 (NT2), idiopathic hypersomnia (IH) (non-hypocretin-deficient conditions), in comparison to controls. We hypothesized that NT1 patients would be less vulnerable to drug abuse and addiction compared to other hypersomniac patients and controls from general population. We performed a cross-sectional study in French reference centres for rare hypersomnia diseases and included 450 adult patients (median age 35 years; 41.3% men) with NT1 (n = 243), NT2 (n = 116), IH (n = 91), and 710 adult controls. All participants were evaluated for alcohol consumption, smoking habits, and substance (alcohol and illicit drug) abuse and dependence diagnosis during the past year using the Mini International Neuropsychiatric Interview. An increased proportion of both tobacco and heavy tobacco smokers was found in NT1 compared to controls and other hypersomniacs, despite adjustments for potential confounders. We reported an increased regular and frequent alcohol drinking habit in NT1 versus controls but not compared to other hypersomniacs in adjusted models. In contrast, heavy drinkers were significantly reduced in NT1 versus controls but not compared to other hypersomniacs. The proportion of patients with excessive drug use (codeine, cocaine, and cannabis), substance dependence, or abuse was low in all subgroups, without significant differences between either hypersomnia disorder categories or compared with controls. We first described a low frequency of illicit drug use, dependence, or abuse in patients with central hypersomnia, whether Hcrt-deficient or not, and whether drug-free or medicated, in the same range as in controls. Conversely, heavy drinkers were rare in NT1 compared to controls but not to other hypersomniacs, without any change in alcohol dependence or abuse frequency. Although disruption of hypocretin signaling in rodents reduces drug-seeking behaviors, our results do not support that hypocretin deficiency constitutes a protective factor against the development of drug addiction in humans. © 2016 Associated Professional Sleep Societies, LLC.
[Cognitive impairments in alcohol dependence: From screening to treatment improvements].

Alcohol-related cognitive impairments are largely underestimated in clinical practice, even though they could limit the benefit of alcohol treatment and hamper the patient's ability to remain abstinent or to respect his/her therapeutic contract. These neuropsychological deficits can impact the management of patients well before the development of the well-known Korsakoff's syndrome. Indeed, even in the absence of ostensible neurological complications, excessive and chronic alcohol consumption results in damage of brain structure and function. The frontocerebellar circuit and the circuit of Papez, respectively involved in motor and executive abilities and episodic memory, are mainly affected. Those brain dysfunctions are associated with neuropsychological deficits, including deficits of executive functions, episodic memory, social cognition, as well as visuospatial and motor abilities. Such cognitive disorders can interfere with the motivation process to abandon maladjusted drinking behavior in favor of a healthier lifestyle (such as abstinence or controlled alcohol consumption). They can also limit the patient's capacity to fully benefit from treatment (notably psychoeducation and cognitive-behavioural treatments) currently widely proposed in French Addiction departments. In addition, they may contribute to relapse which is multi-determinated. A neuropsychological assessment appears therefore crucial to take relevant clinical decisions. However, very few addiction departments have the human and financial resources to conduct an extensive neuropsychological examination of all patients with alcohol dependence. Some brief screening tools can be used, notably the MOntreal Cognitive Assessment and the Brief Evaluation of Alcohol-Related Neuropsychological Impairments, which has been especially designed to assess cognitive and motor deficits in alcoholism. These tools can be used by non-psychologist clinicians to detect alcohol-related cognitive deficits, which require an extensive cognitive examination conducted by a neuropsychologist. The presence of cognitive dysfunctions in patients early in abstinence should encourage clinicians to adjust the modalities of the treatment. The fact to favor recovery of cognitive functions and brain volumes with abstinence or drastic reduction of alcohol consumption could be a first way to make it possible for patients to be cognitively able to benefit from treatment. Further studies are required to determine whether specifically designed cognitive remediation could boost (accelerate or increase) the recovery of brain functioning. Additionally, a potential effect of thiamine to limit alcohol-related cognitive deficits before the development of neurological complications remains to be determined. In this review, we presented the pattern of structural brain damage and the associated cognitive and motor impairments in alcohol-dependent patients. We then emphasized the harmful effects of neuropsychological deficits in the management of these patients. We also pointed how relevant it is to screen patients with neuropsychological impairments and we focused on the presentation of two brief screening tools for cognitive impairments, especially designed for alcohol-related deficits or not. Finally, we reported how these neuropsychological impairments could be taken into consideration the treatment of alcohol addiction by adjusting its timing and modalities.

Peroxidase is the most important antioxidant enzyme in saliva. Through peroxidation of thiocyanate in the presence of H₂O₂, peroxidase catalyses the formation of bacteriocidic compounds such as hypothiocyanate.The purpose of this study was to evaluate the effect of chronic alcohol intoxication and smoking on the activity of oral peroxidase (OPO). A total of 37 volunteers participated in the study. This cohort consisted of 17 male alcohol-dependent smoking patients after chronic alcohol intoxication (AS group, alcohol + smoking) (mean age: 42 years; range: 26-55) (100-700 g/day of alcohol; 10-20 cigarettes/day) and 20 control male social drinkers(CNS group, control non-smokers) with no history of alcohol abuse or smoking (mean age: 42 years; range:30-53). Salivary peroxidase activity was measured by the colorimetric method. The differences between groups were evaluated using the Mann-Whitney U test. There was significantly higher activity of OPO (p = 0.00001)and significantly lower salivary flow (SF) (p = 0.007) in alcohol-dependent smokers after chronic alcohol intoxication compared to the control group. OPO activity significantly correlated with the number of days of alcohol intoxication, but not with smoking. Gingival index (GI) was significantly higher in smoking alcohol-dependent persons than in the control group, and correlated with OPO activity. The sensitivity of the OPO test was 70% in smoking alcoholics, while specificity was 95%. The increased activity of OPO suggests chronic oxidative stress is more likely due to ethanol action than to smoking. Smoking alcohol-dependent persons have a worse periodontal status than controls. OPO activity as a marker of chronic alcohol abuse may help in the diagnosis of alcoholism.
Engineering redox homeostasis to develop efficient alcohol-producing microbial cell factories.

The biosynthetic pathways of most alcohols are linked to intracellular redox homeostasis, which is crucial for life. This crucial balance is primarily controlled by the generation of reducing equivalents, as well as the (reduction)-oxidation metabolic cycle and the thiol redox homeostasis system. As a main oxidation pathway of reducing equivalents, the biosynthesis of most alcohols includes redox reactions, which are dependent on cofactors such as NADH or NADPH. Thus, when engineering alcohol-producing strains, the availability of cofactors and redox homeostasis must be considered. In this review, recent advances on the engineering of cellular redox homeostasis systems to accelerate alcohol biosynthesis are summarized. Recent approaches include improving cofactor availability, manipulating the affinity of redox enzymes to specific cofactors, as well as globally controlling redox reactions, indicating the power of these approaches, and opening a path towards improving the production of a number of different industrially-relevant alcohols in the near future.

A clinical trial demonstrated that a therapeutic workplace could promote alcohol abstinence in homeless, alcohol-dependent adults. This secondary-data analysis examined rates of homelessness and their relation to the therapeutic workplace intervention and alcohol use during the trial. In the trial, homeless, alcohol-dependent adults could work in a therapeutic workplace for 6 months and were randomly assigned to Unpaid Training, Paid Training, or Contingent Paid Training groups. Unpaid Training participants were not paid for working. Paid Training participants were paid for working. Contingent Paid Training participants were paid for working if they provided alcohol-negative breath samples. Rates of homelessness during the study were calculated for each participant and the three groups were compared. Mixed-effects regression models were conducted to examine the relation between alcohol use (i.e., heavy drinking, drinks per drinking day, and days of alcohol abstinence) and homelessness. Unpaid Training, Paid Training, and Contingent Paid Training participants did not differ in the percentage of study days spent homeless (31%, 28%, 17%; respectively; F(2,94)=1.732, p=0.183). However, participants with more heavy drinking days (b=0.350, p<0.001), more drinks per drinking day (b=0.267, p<0.001), and fewer days of alcohol abstinence (b=-0.285, p<0.001) spent more time homeless. Reducing heavy drinking and alcohol use may help homeless, alcohol-dependent adults transition out of homelessness. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.
UPDATE ON NEUROPHARMACOLOGICAL TREATMENTS FOR ALCOHOLISM: SCIENTIFIC BASIS AND CLINICAL FINDINGS
JOHNSON, BANKOLE A.
2008-01-01
The past decade has seen an expansion of research and knowledge on pharmacotherapy for the treatment of alcohol dependence. The Food and Drug Administration (FDA)–approved medications naltrexone and acamprosate have shown mixed results in clinical trials. Oral naltrexone and naltrexone depot formulations have generally demonstrated efficacy at treating alcohol dependence, but their treatment effect size is small, and more research is needed to compare the effects of different doses on drinking outcome. Acamprosate has demonstrated efficacy for treating alcohol dependence in European trials, but with a small effect size. In U.S. trials, acamprosate has not proved to be efficacious. Research continues to explore which types of alcohol-dependent individual would benefit the most from treatment with naltrexone or acamprosate. The combination of the two medications demonstrated efficacy for treating alcohol dependence in one European study but not in a multi-site U.S. study. Another FDA-approved medication, disulfiram, is an aversive agent that does not diminish craving for alcohol. Disulfiram is most effective when given to those who are highly compliant or who are receiving their medication under supervision. Of the non-approved medications, topiramate is among the most promising, with a medium effect size in clinical trials. Another promising medication, baclofen, has shown efficacy in small trials. Serotonergic agents such as selective serotonin reuptake inhibitors and the serotonin-3 receptor antagonist, ondansetron, appear to be efficacious only among certain genetic subtypes of alcoholic. As neuroscientific research progresses, other promising medications, as well as medication combinations, for treating alcohol dependence continue to be explored. PMID:17880925

Prior research in substance dependence has suggested potential anti-craving effects of repetitive transcranial magnetic stimulation (rTMS) when applied to the dorsolateral prefrontal cortex (DLPFC). However, no single sham-controlled session studies applied to the right DLPFC have been carried-out in recently detoxified alcohol-dependent patients. Furthermore, no studies examined the effect of a single HF-rTMS session on craving in these patients' natural habitat. To further investigate the effect of high-frequency (HF)-rTMS of the right DLPFC on alcohol craving, we performed a prospective, single-blind, sham-controlled study involving 36 hospitalized patients with alcohol dependence syndrome. After successful detoxification, patients were allocated receiving one active or one sham HF-rTMS session. The obsessive-compulsive drinking scale (OCDS) was administered to evaluate the extent of craving just before and after the HF-rTMS session (on Friday), on Saturday and Sunday during the weekend at home, and on Monday when the patient returned to the hospital. One single blind sham-controlled HF-rTMS session applied to the right DLPFC did not result in changes in craving (neither immediately after the stimulation session, nor in patients' natural environment during the weekend). One HF-rTMS stimulation session applied to the right DLPFC had no significant effects on alcohol craving in alcohol dependent patients. One such session could have been too short to alter alcohol craving in a sample of alcohol dependent patients. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Background: The aim of this study was to examine the association between the MAOA-uVNTR gene polymorphism in a homogeneous subgroups of patients with alcohol dependence categorized according to Lesch’s typology. Methods: DNA was provided from alcohol dependent (AD) patients (n = 370) and healthy control subjects (n = 168) all of Polish descent. The history of alcoholism was obtained using the Polish version of the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA). Samples were genotyped using PCR methods. Results: We found no association between alcohol dependence and MAOA gene polymorphism. Conclusions: Lesch typology is a clinical consequence of the disease and its phenotypic description is too complex for a simple genetic analysis. PMID:25809512

Previous randomized, placebo-controlled trials (RCTs) assessing the efficacy of the selective γ-aminobutyric acid (GABA)-B receptor agonist baclofen in the treatment of alcohol dependence have reported divergent results, possibly related to the low to medium dosages of baclofen used in these studies (30-80mg/d). Based on preclinical observations of a dose-dependent effect and positive case reports in alcohol-dependent patients, the present RCT aimed to assess the efficacy and safety of individually titrated high-dose baclofen for the treatment of alcohol dependence. Out of 93 alcohol-dependent patients initially screened, 56 were randomly assigned to a double-blind treatment with individually titrated baclofen or placebo using dosages of 30-270mg/d. The multiple primary outcome measures were (1) total abstinence and (2) cumulative abstinence duration during a 12-week high-dose phase. More patients of the baclofen group maintained total abstinence during the high-dose phase than those receiving placebo (15/22, 68.2% vs. 5/21, 23.8%, p=0.014). Cumulative abstinence duration was significantly higher in patients given baclofen compared to patients of the placebo group (mean 67.8 (SD 30) vs. 51.8 (SD 29.6) days, p=0.047). No drug-related serious adverse events were observed during the trial. Individually titrated high-dose baclofen effectively supported alcohol-dependent patients in maintaining alcohol abstinence and showed a high tolerability, even in the event of relapse. These results provide further evidence for the potential of baclofen, thereby possibly extending the current pharmacological treatment options in alcohol dependence.

To illuminate the meaning of living with alcohol dependency as a woman. The number of women suffering from alcohol dependency is increasing. Today there are shortcomings in knowledge about the lived experiences of being a woman with alcohol dependency; knowledge which might be of importance for meeting these women's specific needs of care. The study has a qualitative design. Fourteen women with alcohol dependency participated in open in-depth interviews. Data were analysed according to a phenomenological-hermeneutic method, and interpreted by help from gender and caring perspectives as well as results from previous research of alcohol dependency. In relation to the women's senses of well-being, four main gender formations were found; An unstable self involving continual and rapid swings between emotional and bodily reactions. Ambivalence - meaning ambiguous feelings towards themselves as human beings and how they lead their lives. Introspectiveness - involving reflections, pondering and being introverted. Attempts to perform normality - covering - dealing with life through various strategies and facades to live up to the expectations of how to behave as a woman. Living with alcohol dependency as a woman constitutes of a rapid shifting everyday life resulting in senses of alienation as well as private introspection leading to self-degradation, and to a lesser extent meaningfulness and hope. It also constitutes of managing to perform normality. When supporting women with alcohol dependency towards wellbeing, professionals need to work towards approaching the woman's inner thoughts, share them and reflect over them together. To support these women to find balance in life, caregivers need to cooperate with the women to find out how best to live a life adjusted to the woman's abilities and wishes. © 2012 Blackwell Publishing Ltd.

Much is still unclear about the role of personality in the structure of common psychiatric disorders such as depressive/anxiety disorders and alcohol dependence. This study will therefore examine whether various traits of negative emotionality and impulsivity showed shared or specific associations with these disorders. Method Cross-sectional data were used from the Netherlands Study of Depression and Anxiety (NESDA), including individuals with no DSM-IV psychiatric disorder (n = 460), depressive/anxiety disorder only (i.e. depressive and/or anxiety disorder; n = 1398), alcohol dependence only (n = 32) and co-morbid depressive/anxiety disorder plus alcohol dependence (n = 358). Aspects of negative emotionality were neuroticism, hopelessness, rumination, worry and anxiety sensitivity, whereas aspects of impulsivity included disinhibition, thrill/adventure seeking, experience seeking and boredom susceptibility. Aspects of negative emotionality formed a homogeneous dimension, which was unrelated to the more heterogeneous construct of impulsivity. Although all aspects of negative emotionality were associated with alcohol dependence only, associations were much stronger for depressive/anxiety disorder only and co-morbid depressive/anxiety disorder with alcohol dependence. The results for impulsivity traits were less profound and more variable, with disinhibition and boredom susceptibility showing modest associations with both depressive/anxiety disorder and alcohol dependence, whereas low thrill/adventure seeking and high disinhibition were more strongly related with the first and the latter, respectively. Our results suggest that depressive/anxiety disorder and alcohol dependence result from shared as well as specific aetiological pathways as they showed the same associations with all aspects of negative emotionality, disinhibition and boredom susceptibility as well as specific associations with thrill/adventure seeking and disinhibition.

Community-dwelling respondents from nationally representative US samples (n = 33,231) were interviewed in 2000–2001 and 2004–2005. Past-year disordered gambling at baseline was associated with the subsequent occurrence of any Axis I psychiatric disorder, any mood disorder, bipolar disorder, generalized anxiety disorder, posttraumatic stress disorder, any substance use disorder, alcohol use disorders, and alcohol dependence disorder after adjustment for sociodemographic variables. After simultaneous adjustment for medical conditions, health-related quality of life, and recent stressful life events, disordered gambling remained significantly related to any mood disorder, generalized anxiety disorder, posttraumatic stress disorder, alcohol use disorders, and alcohol dependence. The clinical implications of these findings are that treatment providers need to screen gambling patients for mood, anxiety, and substance use problems and monitor the possible development of later comorbid conditions.

Little is known about the perceived barriers to quitting smoking among alcohol abusers. In addition to the usual barriers perceived by smokers, alcohol dependent smokers may have a few barriers unique to their addictive lifestyle. The Barriers to Quitting Smoking in Substance Abuse Treatment (BQS-SAT) was administered to 96 alcohol dependent smokers in residential substance abuse treatment. The BQS-SAT is designed to assess perceived barriers to quitting smoking among alcohol abusers using eleven true-false items. One open-ended item was included to gather information about potential additional barriers. The majority of respondents reported withdrawal-related barriers such as expecting to feel irritable, anxious, restless, and about half expected intolerable urges to smoke if they were to quit smoking, as most smokers do. However, concerns about effects on sobriety and needing cigarettes to cope with feeling down were also endorsed by almost half of the patients. Total number of perceived barriers was significantly related to smoking history, expected effects from smoking, and smoking temptation but was not associated with severity of alcohol use or dependence on admission. Providing corrective feedback about these barriers could be useful when addressing smoking with patients who have alcohol abuse or dependence.

Objective While prior studies have reported racial/ethnic disparities in alcohol-related problems at a given level of heavy drinking, particularly lower levels, it is unclear whether these occur in both genders and are an artifact of racial/ethnic differences in drink alcohol content. Such information is important to understanding disparities and developing specific, targeted interventions. This study addresses these questions and examines disparities in specific types of alcohol problems across racial-gender groups. Method Using 2005 and 2010 National Alcohol Survey data (N=7,249 current drinkers), gender-stratified regression analyses were conducted to assess black-white and Hispanic-white disparities in alcohol dependence and negative drinking consequences at equivalent levels of heavy drinking. Heavy drinking was measured using a gender-specific, composite drinking-patterns variable derived through factor analysis. Analyses were replicated using adjusted-alcohol consumption variables that account for group differences in drink alcohol content based on race/ethnicity, gender, age and alcoholic beverage. Results Compared to white men, black and Hispanic men had higher rates of injuries/accidents/health and social consequences, and marginally greater work/legal consequences (p< .10). Hispanic women had marginally higher rates of social consequences. In main effects models controlling for demographics, light drinking and heavy drinking, only black women and men had greater odds of alcohol-related problems relative to whites. Interaction models indicated that compared to whites, black women had greater odds of dependence at all levels of heavy drinking, while both black and Hispanic men had elevated risk of alcohol problems only at lower levels of heavy drinking. Drink alcohol content adjustments did not significantly alter findings for either gender. Conclusions This study highlights the gender-specific nature of racial/ethnic disparities. Interventions focused on reducing heavy drinking might not address disparities in alcohol-related problems that exist at low levels of heavy drinking. Future research should consider the potential role of environmental and genetic factors in these disparities. PMID:24730475

Alcohol is the most commonly used and abused substance worldwide. The emergence of alcohol use disorders, and alcohol dependence in particular, is accompanied by functional changes in brain reward and stress systems, which contribute to escalated alcohol drinking and seeking. Corticotropin-releasing factor (CRF) systems have been critically implied in the transition toward problematic alcohol drinking and alcohol dependence. This review will discuss how dysregulation of CRF function contributes to the vulnerability for escalated alcohol drinking and other consequences of alcohol consumption, based on preclinical evidence. CRF signaling, mostly via CRF1 receptors, seems to be particularly important in conditions of excessive alcohol taking and seeking, including during early and protracted withdrawal, relapse, as well as during withdrawal-induced anxiety and escalated aggression promoted by alcohol. Modulation of CRF1 function seems to exert a less prominent role over low to moderate alcohol intake, or to species-typical behaviors. While CRF mechanisms in the hypothalamic–pituitary–adrenal axis have some contribution to the neurobiology of alcohol abuse and dependence, a pivotal role for extra-hypothalamic CRF pathways, particularly in the extended amygdala, is well characterized. More recent studies further suggest a direct modulation of brain reward function by CRF signaling in the ventral tegmental area, nucleus accumbens, and the prefrontal cortex, among other structures. This review will further discuss a putative role for other components of the CRF system that contribute for the overall balance of CRF function in reward and stress pathways, including CRF2 receptors, CRF-binding protein, and urocortins, a family of CRF-related peptides.

A randomized controlled trial for an innovative alcohol-adapted anger management treatment (AM) for outpatient alcohol dependent individuals scoring moderate or above on anger is described. AM treatment outcomes were compared to those of an empirically-supported intervention, Alcoholics Anonymous Facilitation treatment (AAF). Clients in AM, relative to clients in AAF, were hypothesized to have greater improvement in anger and anger-related cognitions and lesser AA involvement during the 6-month follow-up. Anger-related variables were hypothesized to be stronger predictors of improved alcohol outcomes in the AM treatment condition and AA involvement was hypothesized to be a stronger predictor of alcohol outcomes in the AAF treatment group. Seventy-six alcohol dependent men and women were randomly assigned to treatment condition and followed for 6 months after treatment end. Both AM and AAF treatments were followed by significant reductions in heavy drinking days, alcohol consequences, anger, and maladaptive anger-related thoughts and increases in abstinence and self-confidence regarding not drinking to anger-related triggers. Treatment with AAF was associated with greater AA involvement relative to treatment with AM. Changes in anger and AA involvement were predictive of posttreatment alcohol outcomes for both treatments. Change in trait anger was a stronger predictor of posttreatment alcohol consequences for AM than for AAF clients; during-treatment AA meeting attendance was a stronger predictor of posttreatment heavy drinking and alcohol consequences for AAF than for AM clients. Anger-related constructs and drinking triggers should be foci in treatment of alcohol dependence for anger-involved clients. Copyright © 2015 Elsevier Inc. All rights reserved.

Harmful use of alcohol is one of the globally recognized causes of health hazards. There are no data on alcohol consumption from Andaman and Nicobar Islands. The objective of the study was to assess the prevalence and pattern of alcohol use among the population of Andaman and Nicobar Islands, India. A representative sample of 18,018 individuals aged ≥14 years were chosen by multistage random sampling and administered a structured instrument, a modified version of the Gender, Alcohol, and Culture: An International Study (GENACIS) which included sociodemographic details and Alcohol Use Disorders Identification Test (AUDIT). The overall prevalence of alcohol consumption was 35% among males and over 6.0% in females, aged 14 and above. Two out of every five alcohol users fit into a category of hazardous drinkers. One-fourth of the total users (23%) are alcohol dependents. Both the hazardous drinking and dependent use are high among males compared to females. Almost 18.0% of male drinkers and 12.0% of female drinkers reported heavy drinking on typical drinking occasions. The predominant beverages consumed were in the category of homebrews such as toddy and handia. The present study highlights the magnitude of hazardous drinking and alcohol dependence in Andaman and Nicobar Islands, India and the complex sociocultural differences in the pattern of alcohol use. Based on the AUDIT data, among the population of Andaman and Nicobar Islands (aged 14 and above), one out of ten requires active interventions to manage the harmful impact of alcohol misuse.

Abstinent alcohol dependent individuals commonly employ thought suppression to cope with stress and intrusive cognitions about alcohol. This strategy may inadvertently bias attention toward alcohol-related stimuli while depleting neurocognitive resources needed to regulate urges, manifested as decreased heart rate variability (HRV) responsivity to alcohol cues. The present study tested the hypothesis that trait and state thought suppression, impaired regulation of urges, and alcohol attentional bias as measured by the Addiction-Stroop would have significant effects on the HRV responsivity of 58 adults in residential treatment for alcohol dependence (mean age = 39.6 ± 9.4, 81% female) who participated in an affect-modulated cue-reactivity protocol. Regression analyses controlling for age, level of pre-treatment alcohol consumption, and baseline HRV indicated that higher levels of trait thought suppression, impaired regulation of alcohol urges, and attentional fixation on alcohol cues were associated with lower HRV responsivity during stress-primed alcohol cue-exposure. Moreover, there was a significant state X trait suppression interaction on HRV cue-responsivity, such that alcohol dependent persons reporting high levels of state and trait suppression exhibited less HRV during cue-exposure than persons reporting low levels of state and trait suppression. Results suggest that chronic thought suppression taxes regulatory resources reflected in reduced HRV responsivity, an effect that is particularly evident when high trait suppressors engage in intensive suppression of drinking-related thoughts under conditions of stress. Treatment approaches that offer effective alternatives to the maladaptive strategy of suppressing alcohol urges may be crucial for relapse prevention. PMID:21967855

Chronic alcoholism is associated with the development of cardiac and peripheral autonomic nervous system (ANS) pathology. The aim of the present study was to evaluate the extent to which recovery in ANS function could be demonstrated over the first 4 months of abstinence. Fifteen alcoholics (7 women) were studied on three occasions: within a month of detoxification, at approximately 2 months post-detox, and at 4 months post-detox. Thirteen control subjects (6 women) were also studied on three occasions with inter-study intervals matching those of the alcoholics. Six alcoholics relapsed, 48.7 ± 27.9 days following the initial PSG session. ANS function was assessed in the first part of stable non-rapid eye movement sleep. Frequency-domain power spectral analysis of heart rate variability (HRV) produced variables including: heart rate (HR), total power (TP; an index representing total HR variability), High Frequency power (HFa; an index reflecting cardiac vagal modulation), HF proportion of total power (HFprop sympathovagal balance), and HF peak frequency (HFpf; an index reflecting respiration rate). Overall, high total and high frequency variability and low sympathovagal balance and myocardial contractility are considered as desired conditions to promote cardiovascular health. At initial assessment, alcoholics had a higher HR (p < 0.001) and respiratory rate (p < 0.01), and lower vagal activity (HFa; p < 0.01) than controls. Alcoholics showed evidence of recovery in HR (p = 0.039) and HFa (p = 0.031) with 4 months of abstinence. Alcoholics with higher TP at the initial visit showed a greater improvement in TP from the initial to the 4 month follow-up session (r = 0.75, p < 0.05). Alcoholics showed substantial recovery in HR and vagal modulation of HRV with 4 months of abstinence, with evidence that the extent of recovery in HRV may be partially determined by the extent of alcohol dependence-related insult to the cardiac ANS system. These data support other studies showing recovery in a number of ANS, central nervous system, and behavioral domains with abstinence, even in those with long-term dependence.

Emotional and interpersonal deficits play a crucial role in alcohol-related disorders as they predict alcohol consumption and relapse. Recent models of emotion regulation in psychopathology postulate that these deficits are centrally related to increased abstract/analytic repetitive thinking, combined with reduced concrete/experiential repetitive thinking. As this assumption has not been tested in addictions, this study aimed at investigating repetitive thinking modes in a large sample of alcohol-dependent individuals. One hundred recently detoxified alcohol-dependent individuals (29 females; mean age = 49.51-years-old) recruited during the 3rd week of their treatment in a detoxification center were compared to 100 healthy controls (29 females; mean age = 48.51-years-old) recruited in the experimenters' social network, matched at the group level for age, gender, and educational level. All participants completed the Mini Cambridge Exeter Repetitive Thought Scale measuring abstract/analytic and concrete/experiential repetitive thinking modes as well as complementary psychopathological measures (Beck Depression Inventory and State/Trait Anxiety Inventory). Alcohol-dependent individuals have similar levels of concrete repetitive thinking as controls but report significantly higher levels of abstract repetitive thinking (p < 0.001; d = 1.28). This effect remains significant after controlling for depression and anxiety. Relative to healthy controls, alcohol-dependent patients report more frequent use of abstract/analytic repetitive thinking, with preserved concrete/experiential thinking. Despite the cross-sectional nature of the study, the frequent use of abstract repetitive thinking thus appears to constitute a main feature of alcohol-dependence.

Though studies have examined attentional bias for alcohol-related information among alcohol-dependent individuals, few have examined memory bias. This study examined attention and recognition memory biases for alcohol-related information among patients recently admitted to residential alcohol treatment (n=100; 40% female). Participants completed a computerized attentional task wherein they classified a centrally-presented digit as odd or even. On some trials, an alcohol word, neutral word, or anagram was presented along with the digit. On these dual trials participants first classified the digit and then classified the other stimulus as a word or nonword. Participants took longer to classify digits that appeared with alcohol words compared to neutral words; suggesting the alcohol words distracted them from processing the digit. In a subsequent recognition memory test, participants showed significantly higher hit rates (i.e., correctly classifying an old item as old) and false alarm rates (i.e., incorrectly classifying a new item as old) to the alcohol words compared to the neutral words, and they also showed a more liberal response bias to alcohol words. The findings suggest that alcohol-dependent individuals exhibit both attention and memory bias for alcohol-related information. Copyright © 2012 Elsevier Ltd. All rights reserved.

Background and Objectives Childhood maltreatment is related to alcohol use as well as psychological distress in young adulthood. Few studies have examined whether psychological distress mediates the relationship between child maltreatment and alcohol use. We examined the role of psychological distress in linking child maltreatment subtypes (ie, emotional abuse, physical abuse, sexual abuse, neglect) to four patterns of alcohol use, including frequency of alcohol use, binge drinking, alcohol-related problems, and alcohol dependence. Methods We used a community sample of young adults (N=337), who completed an interview assessing exposure to childhood maltreatment, current psychological distress, and drinking behaviors. Results Emotional abuse was associated with psychological distress, whereas psychological distress was related to more pathological drinking behaviors such as alcohol-related problems and alcohol dependence. Subsequent analyses indicated significant mediated effects between emotional abuse and alcohol-related problems and alcohol dependence via psychological distress, even after controlling for demographic factors, other maltreatment subtypes, parental alcoholism, and peer alcohol use. Conclusions and Scientific Significance Findings suggest that among four types of childhood maltreatment, emotional abuse might be the major driver of pathological drinking among child maltreatment victims. Interventions aimed at negative emotionality may be useful in preventing and treating problematic drinking among the victims of childhood emotional abuse. PMID:26346173

Several studies support an association between electroencephalogram (EEG) voltage and alcohol dependence. However, the distribution of EEG variants also appears to differ depending on an individual's ethnic heritage, suggesting significant genetic stratification of this EEG phenotype. The present study's aims were to investigate the incidence of EEG alpha variants and spectral power in the alpha frequency range in Mexican American young adults based on gender, and personal and family history of alcohol dependence. Clinical ratings (high-, medium-, and low alpha voltage variants) and spectral characteristics of the EEG in the alpha frequency range (7.5-12 Hz) were investigated in young adult (age 18-25 years) Mexican American men (n=98) and women (n=138) who were recruited from the community. Nineteen percent (n=45) of the participants had a low-voltage alpha EEG variant, 18% had a high-voltage variant, and 63% had a medium-voltage variant. There were no significant differences in the distribution of the EEG variants based on family history of alcohol dependence. There was a significant relationship between gender and the three alpha variants (chi2=9.7; df=2; P<.008), and there were no male participants with alcohol dependence with high alpha variants (chi2=5.8; df=2; P<.056). Alcohol dependence, but not a family history of alcohol dependence, was associated with lower spectral power in the alpha frequency range in the right (F=4.4; df=1,96; P<.04) and left (F=5.3; df=1.96; P<.02) occipital areas in the men but not in the women. In conclusion, in this select population of Mexican American young adults, male gender and alcohol dependence are associated with an absence of high-voltage alpha variants and lower alpha power in the EEG. These data suggest that EEG low voltage, a highly heritable trait, may represent an important endophenotype in male Mexican Americans that may aid in linking brain function with genetic factors underlying alcohol dependence in this ethnic group.
Experiences of alcohol dependence: a qualitative study.

Despite the increasing incidence of alcohol misuse and the costs it incurs, British society continues to hold equivocal and ambiguous attitudes towards drinking, and understanding of the nature of alcohol dependence and related issues is limited. This qualitative study aimed to investigate the experiences of individuals with alcohol dependence to enhance understanding of the illness, identify key issues and common themes and provide insight into the experiences of the participants during their alcohol dependent period and recovery. A qualitative approach, using narrative method, was used. Eight participants, all members of Alcoholics Anonymous (AA), were interviewed by the researchers. Using a grounded theory approach and content analysis, the in-depth narratives of the eight participants were systematically analysed. While participants continued to deny the existence of a problem to those around them, their behaviours indicated that they were aware of the problem but were afraid to admit it openly through fear of other people's reactions. Participants generally regarded GPs as helpful but other health professionals less so, especially nurses and Accident and Emergency staff. Participants considered that the success of treatment depended on their own motivation and willingness to engage in radical behaviour change. They considered that reaching this stage represented a turning point in their illness. The point at which this stage was reached appeared to be different for each participant. This systematic analysis of a small sample of alcohol dependent individuals gives insight into their experiences during alcohol dependency and the journey to recovery. The findings suggest that denial of the problem to the outside world occurs simultaneously with individuals being aware of their problem. Participants felt the illness carries a stigma and their negative experiences of health professionals other than GPs suggests that nurses and other health workers need to revise their understanding of alcohol dependence and their approach to it. AA was a significant factor in recovery for these participants.

Aims: Some of the well-known functional alcohol dehydrogenase (ADH) gene variants (e.g. ADH1B*2, ADH1B*3 and ADH1C*2) that significantly affect the risk of alcohol dependence are rare variants in most populations. In the present study, we comprehensively examined the associations between rare ADH variants [minor allele frequency (MAF) <0.05] and alcohol dependence, with several other neuropsychiatric and neurological disorders as reference. Methods: A total of 49,358 subjects in 22 independent cohorts with 11 different neuropsychiatric and neurological disorders were analyzed, including 3 cohorts with alcohol dependence. The entire ADH gene cluster (ADH7–ADH1C–ADH1B–ADH1A–ADH6–ADH4–ADH5 at Chr4) was imputed in all samples using the same reference panels that included whole-genome sequencing data. We stringently cleaned the phenotype and genotype data to obtain a total of 870 single nucleotide polymorphisms with 0< MAF <0.05 for association analysis. Results: We found that a rare variant constellation across the entire ADH gene cluster was significantly associated with alcohol dependence in European-Americans (Fp1: simulated global P = 0.045), European-Australians (Fp5: global P = 0.027; collapsing: P = 0.038) and African-Americans (Fp5: global P = 0.050; collapsing: P = 0.038), but not with any other neuropsychiatric disease. Association signals in this region came principally from ADH6, ADH7, ADH1B and ADH1C. In particular, a rare ADH6 variant constellation showed a replicable association with alcohol dependence across these three independent cohorts. No individual rare variants were statistically significantly associated with any disease examined after group- and region-wide correction for multiple comparisons. Conclusion: We conclude that rare ADH variants are specific for alcohol dependence. The ADH gene cluster may harbor a causal variant(s) for alcohol dependence. PMID:23019235

Background Transactional sex is a risk factor for HIV infection. Alcohol use may increase the risk of transactional sex. No nationally-representative studies have examined the relationship between multiple dimensions of alcohol use and transactional sex in women in South Africa. The aim of the study was to examine the relationship between alcohol dependence, binge drinking and frequency of drinking in the past month and transactional sex in adult women in South Africa. Methods A cross-sectional study using multi-stage, cluster sampling collected data from a nationally representative sample of 5,969 women aged 16–55 years in 2012. The analysis conducted for this paper was restricted to women reporting sexual activity in the past 12 months (n = 3,594). Transactional sex was defined as having received money/gifts in exchange for sex with any sex partner in the past year. Alcohol use measures included: alcohol dependence (≥2 positive responses to the CAGE questionnaire); binge drinking (≥4 drinks for women on one occasion); and drinking frequency in the previous month. Logistic regression models were built to test the hypotheses that each dimension of alcohol use was associated with transactional sex. Results About 6.3% (n = 225) of sexually active women reported transactional sex. Almost a third (30.6%) of sexually active women had ever drunk alcohol, and 19.2% were current (past month) drinkers. Among lifetime drinkers, 28.0% were alcohol dependent and 56.6% were binge drinkers. Alcohol dependent women were twice as likely to report transactional sex (AOR 2.0, 95% CI 1.1–4.3, p<0.05) than those not alcohol dependent. Binge drinkers were 3.1 times more likely to have had transactional sex (95% CI 1.5–6.6, p<0.01) than non-binge drinkers. There was no significant relationship between frequency of drinking in the past month and transactional sex. Conclusion Alcohol dependency and binge drinking are significantly associated with transactional sex in South African women. HIV prevention programmes need to target these women, and address both their alcohol use, as well as the HIV risks associated with transactional sex. PMID:26683812

The effective treatment of depression has been reported to reduce the severity of alcohol use, potentially reflecting improvements in common brain reward circuits. We hypothesized that augmentation therapy of escitalopram with aripiprazole would improve depressive symptoms as well as reduce craving for alcohol and cue-induced brain activity in patients with co-morbid alcohol dependence and major depressive disorder, compared with treatment with escitalopram alone. Thirty-five subjects with major depressive disorder and alcohol dependence were recruited and randomly assigned into 17 aripiprazole + escitalopram and 18 escitalopram only groups. At baseline and following six weeks of treatment, symptoms of depression, craving for alcohol and brain activity were evaluated. During the six week treatment period, Beck Depression Inventory and clinical global index-severity (CGI-S) scores decreased in both the aripiprazole + escitalopram and escitalopram only groups. In addition, following the treatment period, the Korean alcohol urge questionnaire scores in the aripiprazole + escitalopram group were reduced from 23.3±8.4 to 14.3±4.9, compared with those of the escitalopram group of from 21.6±8.4 to 19.3±7.1 (F=13.1, p<0.01). The activity within the anterior cingulate was increased in response to the presentation of alcohol drinking scenes following treatment in the aripiprazole + escitalopram group. The change of brain activity within the left anterior cingulate gyrus in all patients with co-morbid alcohol dependence and major depressive disorder was negatively correlated with the change in craving for alcohol. These findings suggest that the effects of aripiprazole on anterior cingulate cortex might mediate the successful treatment of alcohol dependence in patients with major depressive disorder.

Chronically homeless individuals with alcohol dependence experience severe alcohol-related consequences. It is therefore important to identify factors that might be associated with reduced alcohol-related harm, such as the use of safer-drinking strategies. Whereas effectiveness of safer-drinking strategies has been well-documented among young adults, no studies have explored this topic among more severely affected populations, such as chronically homeless individuals with alcohol dependence. The aims of this study were thus to qualitatively and quantitatively document safer-drinking strategies used in this population. Participants (N=31) were currently or formerly chronically homeless individuals with alcohol dependence participating in a pilot study of extended-release naltrexone and harm-reduction counseling. At weeks 0 and 8, research staff provided a list of safer-drinking strategies for participants to endorse. Implementation of endorsed safer-drinking strategies was recorded at the next appointment. At both time points, strategies to buffer the effects of alcohol on the body (e.g., eating prior to and during drinking) were most highly endorsed, followed by changing the manner in which one drinks (e.g., spacing drinks), and reducing alcohol consumption. Quantitative analyses indicated that all participants endorsed safer-drinking strategies, and nearly all strategies were implemented (80–90% at weeks 0 and 8, respectively). These preliminary findings indicate that chronically homeless people with alcohol dependence use strategies to reduce harm associated with their drinking. Larger randomized controlled trials are needed to test whether interventions that teach safer-drinking strategies may reduce overall alcohol-related harm in this population. PMID:25690515

Nalmefene is a µ and δ opioid receptor antagonist, κ opioid receptor partial agonist that has recently been approved in Europe for treating alcohol dependence. It offers a treatment approach for alcohol-dependent individuals with "high-risk drinking levels" to reduce their alcohol consumption. However, the neurobiological mechanism underpinning its effects on alcohol consumption remains to be determined. Using a randomized, double-blind, placebo-controlled, within-subject crossover design we aimed to determine the effect of a single dose of nalmefene on striatal blood oxygen level-dependent (BOLD) signal change during anticipation of monetary reward using the monetary incentive delay task following alcohol challenge. Twenty-two currently heavy-drinking, non-treatment-seeking alcohol-dependent males were recruited. The effect of single dose nalmefene (18 mg) on changes in a priori defined striatal region of interest BOLD signal change during reward anticipation compared with placebo was investigated using functional magnetic resonance imaging. Both conditions were performed under intravenous alcohol administration (6% vol/vol infusion to achieve a target level of 80 mg/dL). Datasets from 18 participants were available and showed that in the presence of the alcohol infusion, nalmefene significantly reduced the BOLD response in the striatal region of interest compared with placebo. Nalmefene did not alter brain perfusion. Nalmefene blunts BOLD response in the mesolimbic system during anticipation of monetary reward and an alcohol infusion. This is consistent with nalmefene's actions on opioid receptors, which modulate the mesolimbic dopaminergic system, and provides a neurobiological basis for its efficacy.

Meta-analyses were conducted to determine the magnitude of relationships between polymorphisms in 2 genes, ALDH2 and ADH1B, with alcohol dependence in Asians. For each gene, possession of 1 variant [asterisk]2 allele was protective against alcohol dependence, and possession of a 2nd [asterisk]2 allele did not offer significant additional…

The neurotransmitter serotonin is understood to control mood and drug response. Carrying a genetic variant in the serotonin transporter gene (5HTT) may increase the risk of major depressive disorder and alcohol dependence. Previous estimates of the association of the S allele of 5HTTLPR polymorphism with major depressive disorder and alcohol dependence have been inconsistent. For the systematic review, we used PubMed MEDLINE and Discovery of The University of Melbourne to search for all relevant case-control studies investigating the associations of 5HTTLPR polymorphism with major depressive disorder and alcohol dependence. Summary odds ratios (OR) and their 95% confidence intervals (CI) were estimated. To investigate whether year of publication, study population or diagnostic criteria used were potential sources of heterogeneity, we performed meta-regression analyses. Publication bias was assessed using Funnel plots and Egger's statistical tests. We included 23 studies of major depressive disorder without alcohol dependence containing 3392 cases and 5093 controls, and 11 studies of alcohol dependence without major depressive disorder containing 2079 cases and 2273 controls. The summary OR for homozygote carriers of the S allele of 5HTTLPR polymorphism compared with heterozygote and non-carriers combined (SS vs SL+LL genotype) was 1.33 (95% CI = [1.19, 1.48]) for major depressive disorder and 1.18 (95% CI = [1.01, 1.38]) for alcohol dependence. The summary OR per S allele of 5HTTLPR polymorphism was 1.16 (95% CI = [1.08, 1.23]) for major depressive disorder and 1.12 (95% CI = [1.01, 1.23]) for alcohol dependence. Meta-regression models showed that the associations did not substantially change after adjusting for year of publication, study population and diagnostic criteria used. There was no evidence for publication bias of the studies included in our meta-analysis. Our meta-analysis confirms that individuals with the homozygous S allele of 5HTTLPR polymorphism are at increased risks of major depressive disorder as well as alcohol dependence. Further studies are required to investigate the association between 5HTTLPR polymorphism and the comorbidity of major depressive disorder and alcohol dependence as well as gene × environmental interactions. © The Royal Australian and New Zealand College of Psychiatrists 2016.

The objective of the present study was the retrospective analysis of the materials collected by the Republican Bureau of Forensic Medical Expertise, Ministry of Health and Social Development of Chuvash Republic, during the period from 1997 till 2002 for the elucidation of the chronological patterns of sudden cardiac death (SCD) associated with alcohol consumption depending on the sex and age of the victims, days of the week and months of the year as well as weather conditions. It was shown that the peak of mortality among men and women taking no alcohol fell on Monday. It was highest in May and decreased by February. The alcohol consumption significantly changes the chronological patterns of mortality from cardiovascular pathology. It was highest among the women abusing alcohol in August and October. The study has demonstrated a weak negative correlation between the frequency of sudden cardiac death among non-consumers of alcohol and dew-point temperature among the persons having alcohol in blood.
Episodic Future Thinking: Expansion of the Temporal Window in Individuals with Alcohol Dependence.
Snider, Sarah E; LaConte, Stephen M; Bickel, Warren K
2016-07-01
Episodic future thinking (EFT) requires an individual to vividly pre-experience a realistic future event. Inspired by previous reports of reducing delay discounting following EFT in other populations, we examined the effects of engaging alcohol-dependent individuals in EFT or episodic recent thinking (ERT; control) to examine its effects on delay discounting and alcohol purchasing. Participants (n = 50) with alcohol dependence were allocated into EFT or ERT groups and asked to generate positive future or recent past events for each of 5 time points. Participants then completed a delay-discounting task, during which event cues were displayed, and a hypothetical alcohol purchase task. EFT significantly increased valuation of future monetary rewards, while decreasing initial consumption (Q0 ) of alcoholic drinks indicative of lower demand intensity. Two additional findings suggest potential moderators of this effect. EFT more readily influenced individuals with lower Alcohol Use Disorders Identification Test scores, and self-reported cue valence differed between groups. Together, these results suggest a widening of alcohol-dependent individuals' temporal window following engagement of EFT. While our data suggest that EFT may be moderated by certain susceptibility criteria, exercises such as EFT could be easily adaptable as a potential therapeutic tool for use in rehabilitation programs.

Background While some argue that social network ties of individuals with alcohol use disorders (AUD) are robust, there is evidence to suggest that individuals with AUDs have few social network ties, which are a known risk factor for health and wellness. Objectives Social network ties to friends, family, co-workers and communities of individuals are compared among individuals with a past-year diagnosis of alcohol dependence or alcohol abuse to individuals with no lifetime diagnosis of AUD. Method Respondents from Wave 2 of the National Epidemiologic Survey on Alcohol Related Conditions (NESARC) were assessed for the presence of past-year alcohol dependence or past-year alcohol abuse, social network ties, sociodemographics and clinical characteristics. Results Bivariate analyses showed that both social network size and social network diversity was significantly smaller among individuals with alcohol dependence, compared to individuals with alcohol abuse or no AUD. When social and clinical factors related to AUD status were controlled, multinomial logistic models showed that social network diversity remained a significant predictor of AUD status, while social network size did not differ among AUD groups. Conclusion Social networks of individuals with AUD may be different than individuals with no AUD, but this claim is dependent on specific AUD diagnosis and how social networks are measured.

Alcohol-dependent patients in early abstinence show an impairment of cognitive functions which can be seen in poor implementation of newly learned skills for avoiding relapse. Executive dysfunction may persist during abstinence in alcohol-dependent persons, thus mitigating long-term abstinence. This study assessed visual memory function and choice of organizational strategies in alcoholics, as these are major factors necessary to implement ongoing behavior changes which are required for maintaining abstinence. We investigated 25 severely alcohol-dependent male patients between days 7 to 10 of abstinence, immediately after clinical withdrawal symptoms have ceased, compared to 15 healthy age, sex, and education matched controls. Pharmacological therapy had been terminated at least four half-lifes before inclusion into the study. Visual perceptual learning and organizational strategies were assessed with the Rey-Osterrieth Complex Figure Test (R-OCF). There were no group differences in copying or recalling the figure, but time differences occurred. Alcoholics and healthy controls performed worse in recalling than in copying. But, alcoholics used less effective organizational strategies. There was a deficit in choice of organizational strategy in newly abstinent and unmedicated alcohol-dependent patients. Due to the imperfect organizational strategies, alcoholics might need auxiliary therapeutic care to strengthen their cognitive ability.

Background Abnormalities of the hypothalamic-pituitary-thyroid (HPT) axis have been reported in alcoholism, however, there is no definitive agreement on the specific thyroid abnormalities and their underlying mechanisms in alcohol dependence (AD). The biological activity of thyroid hormones or the availability of T3 is regulated by the three deiodinase enzymes D1, D2 and D3. In the context of alcohol use, functionally significant single nucleotide polymorphisms (SNP’s) of these deiodinase genes may play a role in HPT dysfunction. Methods The present study explored the effect of three functionally significant SNP’s (D1: rs2235544, D2: rs225014 and rs12885300) of deiodinase genes on drinking behavior and thyroid stimulating hormone (TSH) levels in alcohol dependent (N=521) and control subjects (N=228). Results Rs225014 was associated with significant differences in the amount of naturalistic alcohol drinking assessed by the Timeline Follow-Back (TLFB). Alcohol-dependent subjects had significantly higher thyroid stimulating hormone levels compared to controls; however, there was no effect of genotype on TSH levels for either group. Conclusions These findings extend previous studies on thyroid dysfunction in alcoholism and provide novel, albeit preliminary, information by linking functionally significant genetic polymorphisms of the deiodinase enzymes with alcohol drinking behavior.

Since alcohol use disorders are among the most prevalent and destructive mental disorders, it is critical to address factors contributing to their development and maintenance. Drinking motives are relevant driving factors for consumption. Identifying groups of drinkers with similar motivations may help to specialize intervention components and make treatment more effective and efficient. We aimed to identify and describe distinct motive types of drinkers in dependent males from two diverse cultures (Uganda and Germany) and to explore potential differences and similarities in addiction-related measures. Moreover, we investigated specific links between motive types and childhood maltreatment, traumatic experiences, and symptoms of comorbid psychopathologies. To determine distinct drinking motive types, we conducted latent class analyses concerning drinking motives (Drinking Motive Scale) in samples of treatment-seeking alcohol-dependent men ( N = 75). Subsequently we compared the identified motive types concerning their alcohol consumption and alcohol-related symptoms (Alcohol Use Disorders Identification Test), history of childhood maltreatment (Childhood Trauma Questionnaire), trauma exposure (Violence, War and Abduction Exposure Scale), psychopathology (Posttraumatic Stress Diagnostic Scale, Depression-section of the Hopkins Symptom Checklist, and Brief Symptom Inventory) and deficits in emotion regulation (Difficulties in Emotion Regulation Scale). We found two congruent drinking motive types in both contexts. Reward-oriented drinking motives like the generation of positive feelings and enhancing performance were endorsed almost equally by both motive types, whereas high relief motive endorsement characterized one group, but not the other. The relief motive type drank to overcome aversive feelings, withdrawal, and daily hassles and was characterized by higher adversity in general. Emotional maltreatment in childhood and psychopathological symptoms were reported to a significantly greater extent by relief drinkers (effect sizes of comparisons ranging from r = 0.25 to r = 0.48). However, the motive types did not differ significantly on alcohol consumption or alcohol-related symptoms and traumatic experiences apart from childhood maltreatment. The chronology of addiction development and patterns of drinking motivation seem to be similar across cultures, i.e., that motive targeting interventions might be applicable cross-culturally. Addressing comorbid symptomatology should be a key treatment component for relief drinkers, whereas finding alternatives for the creation of positive feelings and ways to counteract boredom and inactivity should be a general treatment element.

Hispanics are heterogeneous in national origin, evidenced by wide ranges of alcohol abuse and dependence rates across different Hispanic national groups. This paper examines associations between 12-month rates of DSM-IV alcohol abuse and dependence with birthplace and acculturation. The 2006 Hispanic Americans Baseline Alcohol Survey, using a multistage cluster sample design, interviewed 5224 adults (18+ years) in five selected U.S. metropolitan areas: Miami, New York, Philadelphia, Houston, and Los Angeles. Comprehensive data on drinking behavior were collected and the analyses include bivariate and multivariate regression techniques. Alcohol abuse and dependence rates were higher among U.S.-born Puerto Ricans and South/Central Americans compared to their foreign-born counterparts, while no such differences were found for Cuban and Mexican Americans. Overall, those with higher acculturation report higher rates of abuse and dependence (statistically significant only for abuse among Puerto Ricans). Risk factors for abuse include being male and being in the high acculturation group. Risk factors for dependence include being male, being Puerto Rican or Mexican American, having less than a college education, and being U.S.-born. Hispanics were found to share several common risk factors with the larger U.S. population for abuse and dependence, such as male gender, lower education, and lower income.

To compare the discriminant validity of the DSM-IV and the ICD-10 classification of alcohol use disorders (AUD) with an alternative classification, the craving withdrawal model (CWM). CWM requires craving and withdrawal for the diagnosis of alcohol dependence and raises the alcohol abuse threshold to two DSM-IV AUD criteria. Data were derived from The Netherlands Mental Health Survey and Incidence Study, a large representative sample of the general Dutch population. In the present study, only non-abstinent subjects were included (n=6041). Three diagnostic systems (DSM-IV, ICD-10, and CWM) were compared using the following discriminant variables: alcohol intake, psychiatric comorbidity, functional status, familial alcohol problems, and treatment sought. The year prevalence of CWM alcohol dependence was lower than the prevalence of ICD-10 and DSM-IV dependence (0.3% vs 1.4% and 1.4%). The year prevalence of abuse was similar for CWM and DSM-IV (4.7 and 4.9%), but lower for ICD-10 harmful use (1.7%). DSM-IV resulted in a poor distinction between normality and abuse and ICD-10 resulted in a poor distinction between harmful use and dependence. In contrast, the CWM distinctions between normality and abuse, and between abuse, and dependence were significant for most of the discriminant variables. This study indicates that CWM improves the discriminant validity of AUD diagnoses. The predictive validity of the CWM for alcohol and other substance use disorders remain to be studied.

Long-term changes in brain gene expression have been identified in alcohol dependence, but underlying mechanisms remain unknown. Here, we examined the potential role of microRNAs for persistent gene expression changes in the rat medial prefrontal cortex after a history of alcohol dependence. Two-bottle free-choice alcohol consumption increased following 7-week exposure to intermittent alcohol intoxication. A bioinformatic approach using microarray analysis, qPCR, bioinformatic analysis, and microRNA-mRNA integrative analysis identified expression patterns indicative of a disruption in synaptic processes and neuroplasticity. 41 rat-microRNAs and 165 mRNAs in the medial prefrontal cortex were significantly altered after chronic alcohol exposure. A subset of the microRNAs and mRNAs was confirmed by qPCR. Gene ontology categories of differential expression pointed to functional processes commonly associated with neurotransmission, neuroadaptation, and synaptic plasticity. microRNA-mRNA expression pairing identified 33 microRNAs putatively targeting 89 mRNAs suggesting transcriptional networks involved in axonal guidance and neurotransmitter signaling. Our results demonstrate a significant shift in microRNA expression patterns in the medial prefrontal cortex following a history of dependence. Due to their global regulation of multiple downstream target transcripts, microRNAs may play a pivotal role in the reorganization of synaptic connections and long term neuroadaptations in alcohol dependence. microRNA-mediated alterations of transcriptional networks may be involved in disrupted prefrontal control over alcohol-drinking observed in alcoholic patients.

Background Alcohol use disorders are well recognized to be common, debilitating, and the risk of developing them is influenced by family history. The subjective response to alcohol may be determined familialy and related to the risk of developing alcoholism. The aim of this study was to evaluate differences between family history positive (FHP) and family history negative (FHN) individuals in their response to alcohol within the domains of subjective, coordination, and cognitive effects using an IV clamping method of alcohol administration. Methods Two groups of healthy subjects, those with a FHP (n=65) vs. those who were FHN (n=115), between the ages of 21-30, participated in three test days. Subjects were scheduled to receive placebo, low dose ethanol (target BrAC=40mg%), and high dose ethanol (target BrAC=100mg%) on three separate test days at least three days apart in a randomized order under double-blind conditions. Outcome measures included subjective effects, measures of coordination and cognitive function. Results Both low and high dose alcohol led to dose-related stimulant and sedative subjective effects as measured the Biphasic Alcohol Effects Scale (BAES) and subjective measures of “high” and “drowsy” measured on a visual analog scale (VAS) However, there were no effects of family history. Similar dose-related effects were observed on cognitive and coordination related outcomes, but were not moderated family history. Conclusions Results from this study showed that healthy individuals responded to an IV alcohol challenge in a dose-related manner; however, there were no significant differences on subjective response, or on ethanol-induced impairment of coordination or cognition, between individuals with a positive family history for alcoholism and those with a negative family history. Results suggest that FH may not be a specific enough marker of risk, particularly in individuals who are beyond the age where alcohol use disorders often develop. PMID:23895557
Traumas and other adverse life events in adolescents with alcohol abuse and dependence.

Clinical observation suggests that adolescents with alcohol use disorders often have complex histories that include childhood maltreatment and other traumas. The aim of this study was to determine the relationships among adolescent alcohol use disorders and a broad range of traumas and adverse life events. The subjects were 132 adolescents with alcohol dependence, 51 adolescents with alcohol abuse, and 73 adolescents recruited from the community as a control group. Trauma history was assessed by a semistructured interview and other adverse life events by questionnaire. Traumatic events reflecting interpersonal violence had occurred in many of the adolescents with alcohol dependence and abuse and few of the control adolescents. Adolescents with alcohol abuse or dependence, compared with control subjects, were 6 to 12 times more likely to have a physical abuse history and 18 to 21 times more likely to have a sexual abuse history. Sexual abuse was more common in females, and victimization by other violent acts was more common in males. Many other adverse life events were also significantly more common in the alcohol use disorder groups than in the control group, including having a close friend die, arguments within the family, and legal difficulties. These results demonstrate that trauma and other adverse life events are strongly associated with alcohol use disorders in adolescents. Clinical screening of adolescents with alcohol use disorders for a range of traumatic events is recommended.

A substantial body of literature suggests that gamma-aminobutyric acid (GABA) may be involved in the neurochemical pathways contributing to alcohol use and related disorders. Chromosome 5 contains a cluster of GABA(A) receptor genes, GABRA1, GABRA6, GABRB2, and GABRG2, which have been among the most extensively studied in relation to alcohol use. These studies have yielded mixed results. Using data from large, multiplex alcoholic families collected as part of the Collaborative Study on the Genetics of Alcoholism (COGA), we sought to provide more conclusive evidence regarding the role of the GABA(A) receptor genes on chromosome 5. Multiple single nucleotide polymorphisms (SNPs) were tested in each of the four chromosome 5q GABA(A) receptor genes, and we conducted both classic trio-based association analyzes and extended pedigree analyzes. We found no consistent evidence of association with alcohol dependence or alcohol dependence comorbid with antisocial personality disorder (ASPD) for any of the regions tested in the chromosome 5 GABA(A) receptor genes. These analyses suggest that the GABA(A) receptor genes on chromosome 5 do not play a strong role in alcohol dependence. Future studies are planned to test whether these genes are more important in influencing behavioral endophenotypes related to the risk of alcohol dependence. Copyright 2004 Wiley-Liss, Inc.

Background Most physiological studies interested in alcohol-dependence examined ethanol as a pharmacological agent rather than a nutrient. We conducted two studies, which assessed the metabolic and endocrine factors involved in the regulation of alcohol and nutrient intake in alcohol-dependent (AD) subjects. We also examined the potential role of a disruption in energy balance in alcohol-dependence. Methods and Results In Study-1, quantitative dietetic interviews of eating and drinking habits were conducted with 97 AD subjects. The population was split around a median alcohol intake value of 12.5 kcal/kg/day. The results showed that the “low alcohol” drinking AD subjects had high Body Mass Index (BMI) and Fat Mass (FM) and alcohol intake was compensated for by a decrease in non-alcoholic intakes. “High alcohol” drinking AD subjects, on the other hand, had low BMI and FM and the total caloric intakes were largely above norms. In Study-2, 24 AD inpatients were submitted to dietetic interviews, calorimetry and blood samplings for the measurement of biomarkers of the regulation of metabolism and satiety, on day 2, 5 and 16 of abstinence. These patients were compared with 20 controls matched for age and gender. We observed in AD patients an increase in cortisol, leptin and PYY plasma levels and a decrease in ghrelin, which might explain the observed decrease in non-alcoholic intakes. However, alcoholic and non-alcoholic intakes correlated positively with basal metabolism and negatively with leptin and leptin/BMI. Conclusion For individuals consuming below12.5 kcal/kg/day of alcohol, alcohol intake is compensated for by a decrease in non-alcoholic nutrient intakes, probably due to changes in metabolic and satiety factors. For individuals consuming above 12.5 kcal/kg/day of alcohol, alcohol accelerates metabolism and decreases fat mass and leptin levels, and the total caloric intake largely exceeds norms. A dual model for regulation of energy intake in AD subjects is proposed. PMID:22808013

Study Objectives: Basic experiments support the impact of hypocretin on hyperarousal and motivated state required for increasing drug craving. Our aim was to assess the frequencies of smoking, alcohol and drug use, abuse and dependence in narcolepsy type 1 (NT1, hypocretin-deficient), narcolepsy type 2 (NT2), idiopathic hypersomnia (IH) (non-hypocretin-deficient conditions), in comparison to controls. We hypothesized that NT1 patients would be less vulnerable to drug abuse and addiction compared to other hypersomniac patients and controls from general population. Methods: We performed a cross-sectional study in French reference centres for rare hypersomnia diseases and included 450 adult patients (median age 35 years; 41.3% men) with NT1 (n = 243), NT2 (n = 116), IH (n = 91), and 710 adult controls. All participants were evaluated for alcohol consumption, smoking habits, and substance (alcohol and illicit drug) abuse and dependence diagnosis during the past year using the Mini International Neuropsychiatric Interview. Results: An increased proportion of both tobacco and heavy tobacco smokers was found in NT1 compared to controls and other hypersomniacs, despite adjustments for potential confounders. We reported an increased regular and frequent alcohol drinking habit in NT1 versus controls but not compared to other hypersomniacs in adjusted models. In contrast, heavy drinkers were significantly reduced in NT1 versus controls but not compared to other hypersomniacs. The proportion of patients with excessive drug use (codeine, cocaine, and cannabis), substance dependence, or abuse was low in all subgroups, without significant differences between either hypersomnia disorder categories or compared with controls. Conclusions: We first described a low frequency of illicit drug use, dependence, or abuse in patients with central hypersomnia, whether Hcrt-deficient or not, and whether drug-free or medicated, in the same range as in controls. Conversely, heavy drinkers were rare in NT1 compared to controls but not to other hypersomniacs, without any change in alcohol dependence or abuse frequency. Although disruption of hypocretin signaling in rodents reduces drug-seeking behaviors, our results do not support that hypocretin deficiency constitutes a protective factor against the development of drug addiction in humans.

The present study evaluated the possible alcohol dependence and related problems among adolescents and determined possible associations with socioeconomic factors and gender. A cross-sectional study was conducted with a representative sample of 936 adolescents aged 15 to 19 years enrolled at public and private schools in the city of Belo Horizonte, Brazil. Data related to alcohol consumption and associated problems were collected using the Alcohol Use Disorder Identification Test (AUDIT). The Social Vulnerability Index (SVI), mother's schooling and type of school were used to assess socioeconomic factors. Statistical analysis involved the chi-square test (p < 0.05) and Poisson regression. The prevalence of possible dependence was 16.4%, 52.1% reported concern of a family member regarding the adolescent's alcohol consumption. Female adolescents were less likely to exhibit possible dependence in comparison to males. Participants with living in a low vulnerability area were more likely to consume alcohol in comparison to those living in underprivileged areas. The results of the present study demonstrate that possible dependence was significantly associated with the male gender and low social vulnerability.
The role of salsolinol in alcohol intake and withdrawal.

We studied the urinary excretion of the tetrahydroisoquinoline (TIQ) salsolinol, formed from acetaldehyde and dopamine, in both severely and moderately dependent alcoholics during withdrawal from alcohol and subsequent challenge with an acute dose of alcohol and L-dopa, and compared these results with controls. Plasma acetaldehyde and alcohol levels in a sub-population of severely dependent withdrawn alcoholic and control subjects following an acute dose of alcohol were also determined. Salsolinol excretion during the first 4 days of alcohol withdrawal was variable but 10 out of 14 alcoholics showed an increasing trend from day 1 to day 3 and 4 of alcohol withdrawal. L-dopa administration raised salsolinol excretion in controls and withdrawn alcoholics to a uniform extent. Loading of the withdrawn alcoholics with an acute dose of alcohol did not cause an increase in urinary salsolinol concentration (despite increased plasma acetaldehyde). Indeed, 24 h following acute alcohol administration, salsolinol excretion rates were depressed in the alcoholics but not in the controls.

This study investigates the impact of social phobia on adherence to and outcomes 6 months following standard alcohol treatment and Alcoholics Anonymous (AA) group meetings among alcohol-dependent patients with and without social phobia. In a cohort study, 300 detoxified alcohol-dependent individuals in Porto Alegre, Brazil, were interviewed during, as well as 3 and 6 months after hospital detoxification. At both follow-up points, treatment adherence was low and relapse rates were high among patients with and without social phobia, and no significant differences were seen between the two groups of patients in relapse, adherence to AA, or adherence to psychotherapy. Findings from this sample suggest that although alcohol-dependent patients with social phobia showed a tendency for less adherence at AA and felt less integrated with their AA group, social phobia comorbidity was not a significant risk factor for alcohol use relapse or for nonadherence to AA or psychotherapy.

Alcohol is widely consumed; however, excessive use creates serious physical, psychological and social problems and contributes to the pathogenesis of many diseases. Alcohol use disorders (that is, alcohol dependence and alcohol abuse) are maladaptive patterns of excessive drinking that lead to serious problems. Abundant evidence indicates that alcohol dependence (alcoholism) is a complex genetic disease, with variations in a large number of genes affecting a person's risk of alcoholism. Some of these genes have been identified, including two genes involved in the metabolism of alcohol (ADH1B and ALDH2) that have the strongest known affects on the risk of alcoholism. Studies continue to reveal other genes in which variants affect the risk of alcoholism or related traits, including GABRA2, CHRM2, KCNJ6 and AUTS2. As more variants are analysed and studies are combined for meta-analysis to achieve increased sample sizes, an improved picture of the many genes and pathways that affect the risk of alcoholism will be possible.

Ending homelessness is a major priority of the Department of Veteran Affairs (VA), and alcohol use can be a barrier to stable housing. Clinical trials suggest that depot extended-release naltrexone (XR-NTX) is efficacious in reducing alcohol consumption among alcohol-dependent subjects. An open-label, randomized pilot study sought to examine the feasibility and effectiveness of XR-NTX versus oral naltrexone to improve alcohol consumption and housing stability among homeless, alcohol-dependent veterans at the Providence Veteran Affairs Medical Center. Of 215 potential candidates approached over a 16-month recruitment period, only 15 agreed to consider study entry and 7 were randomized. The primary reasons given for refusal were not wanting an injection; fear of needles; and not wanting to change drinking habits. Only 1 participant in the XR-NTX group returned after the first injection. Three participants in the oral naltrexone group attended all 7 visits and had good outcomes. Although XR-NTX has demonstrated efficacy in reducing heavy drinking, limited acceptance of the injection might reduce its effectiveness among homeless, alcohol-dependent patients.

Motivational interviewing (MI) for the treatment of alcohol and drug problems is typically conducted over 1 to 3 sessions. The current work evaluates an intensive 9-session version of MI (Intensive MI) compared to a standard single MI session (Standard MI) using 163 methamphetamine (MA) dependent individuals. The primary purpose of this paper is to report the unexpected finding that women with co-occurring alcohol problems in the Intensive MI condition reduced the severity of their alcohol problems significantly more than women in the Standard MI condition at the 6-month follow-up. Stronger perceived alliance with the therapist was inversely associated with alcohol problem severity scores. Findings indicate that Intensive MI is a beneficial treatment for alcohol problems among women with MA dependence. © 2013.

This article highlights the research presentations at the satellite symposium on “Brain Pathways to Recovery from Alcohol Dependence” held at the 2013 Society for Neuroscience Annual Meeting. The purpose of this symposium was to provide an up to date overview of research efforts focusing on understanding brain mechanisms that contribute to recovery from alcohol dependence. A panel of scientists from the alcohol and addiction research field presented their insights and perspectives on brain mechanisms that may underlie both recovery and lack of recovery from alcohol dependence. The four sessions of the symposium encompassed multilevel studies exploring mechanisms underlying relapse and craving associated with sustained alcohol abstinence, cognitive function deficit and recovery, and translational studies on preventing relapse and promoting recovery. Gaps in our knowledge and research opportunities were also discussed. PMID:26074423
[Motivational interviewing with alcohol-dependent patients].

Motivational interviewing with alcohol-dependent patients Alcohol-dependent patients do not need to be motivated from the outside. They are mostly ambivalent, and the inner voice, which already speaks for change (change talk), is heard through motivational interviewing, carefully strengthened and developed together with the patient. The practitioner has to deal with the human spirit of motivational interviewing and should be able to communicate with empathy, respect, congruence, and openness. The patient's autonomy should always be maintained. Advice is only given upon request. The conversation style is directive-guiding instead of authoritariansteering. OARS and the EPE principle are the motivational interviewing basics, which are consistently applied over 4 processes of motivational interviewing: engaging, focusing, evocing, and planning. The likelihood of change talk increases as soon as discrepancies between life goals and alcohol consumption emerge. An increased rate of change talk makes a change in behavior more likely. If a patient argues against change (sustain talk), one should not confront, but should consistently work with reflections, reframing, and an emphasis on autonomy. Motivational interviewing can be applied in different settings and populations, should be learned by the entire team (best professional guidance) in teamwork, and be subjected to a critical and constant evaluation.

The neurotrophin brain-derived neurotrophic factor (BDNF) has been suggested to be involved in the development and maintenance of addictive and other psychiatric disorders. Also, interactions of γ-aminobutyric acid (GABA)-ergic compounds and BDNF have been reported. The objective of this study was to investigate serum levels of BDNF over time in alcohol-dependent patients receiving individually titrated high-dose treatment (30-270mg/d) with the GABA-B receptor agonist baclofen or placebo for up to 20 weeks. Serum levels of BDNF were measured in patients of the baclofen/placebo group at baseline (t0), 2 weeks after reaching individual high-dose of baclofen/placebo treatment (t1) and after termination of study medication (t2) in comparison to carefully matched healthy controls. No significant differences in serum levels of BDNF between the baclofen and the placebo group or healthy controls were found at t0, t1, or at t2. Based on these findings, it seems unlikely that baclofen exerts a direct effect on serum levels of BDNF in alcohol-dependent patients. Future studies are needed to further explore the mechanism of action of baclofen and its possible relationship to BDNF in alcohol use disorders. Copyright © 2016 Elsevier Ireland Ltd.

Surrogate alcohol containing methanol, social deprivation and public health in Novosibirsk, Russia.

2016-11-01
Surrogate alcohol, i.e. alcohol not intended or not officially intended for human consumption, continues to play an important role in alcohol consumption in Russia, especially for people with alcohol dependence. Among the different types of surrogate alcohol, there are windshield washer antifreeze liquids; these products are the cheapest kinds of non-beverage alcohol available and thus likely to be used by the most deprived and marginalised groups such as homeless people with alcohol dependence. Although it is well known, that non-beverage alcohol is used for consumption by various groups in Russia, and although there are laws to prohibit the use of methanol as part of windshield washer antifreeze liquids for the very reason that such products could be used as surrogate alcohol, we detected products in retail sale which were a mix of water and methanol only. Methanol poses serious health threats including blindness and death, and there had been repeated methanol deaths from surrogate alcohol in Russia over the last years. If law-enforcement does not change for surrogate products, we can expect more methanol-resulting deaths in the most deprived and marginalized groups of people with alcohol dependence in Russia. In addition, ingredients with questionable safety profiles such as formic acid should also be prohibited in non-beverage alcohol products that are likely to be consumed as surrogate alcohol.

BACKGROUND Despite worldwide consumption of moderate amounts of alcohol, the neural mechanisms that mediate the transition from use to abuse are not fully understood. METHODS Here, we conducted a high-through put screen of the amygdala proteome in mice after moderate alcohol drinking (n = 12/group) followed by behavioral studies (n = 6–8/group) to uncover novel molecular mechanisms of the positive reinforcing properties of alcohol that strongly influence the development of addiction. RESULTS Two-dimensional difference in-gel electrophoresis with matrix assisted laser desorption ionization tandem time-of-flight identified 29 differentially expressed proteins in the amygdala of nondependent C57BL/6J mice following 24 days of alcohol drinking. Alcohol-sensitive proteins included calcium/calmodulin-dependent protein kinase II alpha (CaMKIIα) and a network of functionally linked proteins that regulate neural plasticity and glutamate-mediated synaptic activity. Accordingly, alcohol drinking increased α-amino-3-hydroxy-5-methyl-4-isooxazole receptor (AMPAR) in central amygdala (CeA) and phosphorylation of AMPAR GluA1 subunit at a CaMKII locus (GluA1-Ser831) in CeA and lateral amygdala. Further, CaMKIIα-Thr286 and GluA1-Ser831 phosphorylation was increased in CeA and lateral amygdala of mice that lever-pressed for alcohol versus the nondrug reinforcer sucrose. Mechanistic studies showed that targeted pharmacologic inhibition of amygdala CaMKII or AMPAR activity specifically inhibited the positive reinforcing properties of alcohol but not sucrose. CONCLUSIONS Moderate alcohol drinking increases the activity and function of plasticity-linked protein networks in the amygdala that regulate the positive reinforcing effects of the drug. Given the prominence of positive reinforcement in the etiology of addiction, we propose that alcohol-induced adaptations in CaMKIIα and AMPAR signaling in the amygdala may serve as a molecular gateway from use to abuse.

Nationwide surveys to clarify the characteristics and trends of the drinking behavior of Japanese adults were carried out in 2003, 2008, and 2013. These were periodical cross-sectional surveys. Subjects were chosen through a stratified two-stage random sampling method. The surveys included drinking frequency and amount, ICD-10 alcoholism diagnostic standards, questionnaire for the determination of harmful alcohol use ( Alcohol Use Disorders Identification Test). In 2003, the surveys obtained responses from 2547 people (73% response rate); in 2008, 4123 people (55% response rate); and in 2013, 4153 people (59% response rate). The proportion of lifetime experience of alcohol dependence diagnosed by ICD-10 was 1.9% for male and 0.2% for female, and the estimated number of patients was 1.07 million. The declining trends were observed in the percentage of daily drinkers and the amount of alcohol consumed per week for male. The lowering of the age for consuming their first alcoholic drink and their first drunken experience was observed among female. The gender difference of prevalence of problem drinking is getting smaller. The binge drinking and heavy episodic drinking were observed especially younger generation. The only small proportion of patients with alcohol dependence had received specialized medical care, whereas the many of these visited medical institutions and health screening. The survey observed many hidden alcoholic patients, and showed the possibility that the healthcare facilities and health screening became the place of screening and intervention for alcohol dependence. © The Author 2016.

Animal research supports a central role for corticotropin releasing factor (CRF) in actions of ethanol on brain function. An examination of alcohol consumption in adolescents reported a significant genotype × environment (G × E) interaction involving rs1876831, a CRHR1 polymorphism, and negative events. CRHR1 and at least 4 other genes are located at 17q21.31 in an extremely large block of high linkage disequilibrium resulting from a local chromosomal inversion; the minor allele of rs1876831 is contained within the H2 haplotype. Here we examine whether G × E interactions involving this haplotype and childhood sexual abuse (CSA) are associated with risk for alcohol consumption and dependence in Australian participants (N=1128 respondents from 476 families) of the Nicotine Addiction Genetics project. Telephone interviews provided data on DSM-IV alcohol dependence diagnosis and CSA and enabled calculation of lifetime alcohol consumption factor score (ACFS) from 4 indices of alcohol consumption. Individuals reporting a history of CSA had significantly higher ACFS and increased risk for alcohol dependence. A significant G × E interaction was found for ACFS involving the H2 haplotype and CSA (p<0.017). A similar G × E interaction was associated with protective effects against alcohol dependence risk (odds ratio 0.42; 95%CI 0.20 – 0.89). For each outcome, no significant CSA-associated risk was observed in H2 haplotype carriers. These findings support conducting further investigation of the H2 haplotype to determine the gene(s) responsible. Our results also suggest that severe early trauma may prove to be an important clinical covariate in the treatment of alcohol dependence. PMID:19878140

We conducted a systematic literature review on substance misuse, abuse, and dependence in women veterans, including National Guard/reserve members. We identified 837 articles published between 1980 and 2013. Of 56 included studies, 32 reported rates of alcohol misuse, binge drinking, or other unhealthy alcohol use not meeting diagnostic criteria for abuse or dependence, and 33 reported rates of drug misuse or diagnosed alcohol or drug use disorders. Rates ranged from 4% to 37% for alcohol misuse and from 7% to 25% for binge drinking; among Veterans Health Administration (VA) health-care system outpatients, rates ranged from 3% to 16% for substance use disorder. Studies comparing women veterans and civilians reported no clear differences in binge or heavy drinking. Substance misuse rates were generally lower among women veterans than men veterans. Substance misuse was associated with higher rates of trauma, psychiatric and medical conditions, and increased mortality and suicide rates. Most studies included only VA patients, and many used only VA medical record data; therefore, the reported substance misuse rates likely do not reflect true prevalence. Rates also varied by assessment method, source of data, and the subgroups studied. Further efforts to develop epidemiologically valid prevalence estimates are needed to capture the true health burden of substance misuse in women veterans, particularly those not using VA care.

Alcoholic Beverage Consumption and Chronic Diseases

Epidemiological and experimental studies have consistently linked alcoholic beverage consumption with the development of several chronic disorders, such as cancer, cardiovascular diseases, diabetes mellitus and obesity. The impact of drinking is usually dose-dependent, and light to moderate drinking tends to lower risks of certain diseases, while heavy drinking tends to increase the risks. Besides, other factors such as drinking frequency, genetic susceptibility, smoking, diet, and hormone status can modify the association. The amount of ethanol in alcoholic beverages is the determining factor in most cases, and beverage types could also make an influence. This review summarizes recent studies on alcoholic beverage consumption and several chronic diseases, trying to assess the effects of different drinking patterns, beverage types, interaction with other risk factors, and provide mechanistic explanations.

The objective of this study was to determine whether there are gender-specific associations between trauma exposure and alcohol or drug relapse in alcohol-dependent adults. Participants were 51 men (n = 24) and women (n = 27) with alcohol dependence, 22 (43.1%) of whom relapsed during study participation. Severity of childhood trauma; number of lifetime events evoking fear, helplessness, or horror; and current trauma symptoms all predicted relapse in women, but not in men. These findings highlight the importance of assessing trauma history and providing treatment of trauma-related symptoms for individuals with alcohol and drug dependence, and for women in particular. © American Academy of Addiction Psychiatry.

We estimate the prevalence of alcohol, tobacco and illegal substance use in a national representative sample of adolescents. We also estimate how socio demographic characteristics, household environment and mental health are associated with substance misuse. This is a cross-sectional study using data from the first Brazilian National Alcohol Survey, which gathered information on the use of psychoactive substances in 761 participants aged 14 to 19 years old. Weighted logistic regression was used to calculate adjusted odds ratios. More than half of the adolescents interviewed were regular alcohol users and one out of ten were abusers and/or dependents. Older male adolescents living in urban areas were more likely to present alcohol related disorders and to smoke. Age had an inverse association with illegal substance use. Smokers and those using illegal substances were more likely to report domestic violence while those with alcohol abuse/dependence were more likely to have depression. The high prevalence of alcohol, tobacco and illicit substance consumption among Brazilian adolescents is staggering. Young males with mood disorders from urban areas are more at risk of developing alcohol disorders while illegal drug use is highly associated to household dysfunction in early life. Brazilian growing economy will possibly lead to increased levels of substance use among adolescents if new prevention measures are not implemented. The intensification of law enforcement strategies to reduce psychotropic substances access is required. Copyright © 2012 Elsevier Ltd. All rights reserved.
Deep brain stimulation surgery for alcohol addiction.
Voges, Juergen; Müller, Ulf; Bogerts, Bernhard; Münte, Thomas; Heinze, Hans-Jochen
2013-01-01
The consequences of chronic alcohol dependence cause important health and economic burdens worldwide. Relapse rates after standard treatment (medication and psychotherapy) are high. There is evidence from in vivo investigations and from studies in patients that the brain's reward system is critically involved in the development and maintenance of addictive behavior, suggesting that modification of this system could significantly improve the prognosis of addictive patients. Motivated by an accidental observation, we used the nucleus accumbens (NAc), which has a central position in the dopaminergic reward system for deep brain stimulation (DBS) of alcohol addiction. We report our first experiences with NAc DBS for alcohol dependence and review the literature addressing the mechanisms leading to addiction. Five patients were treated off-label with bilateral NAc DBS for severe alcohol addiction (average follow-up 38 months). All patients experienced significant and ongoing improvement of craving. Two patients remained completely abstinent for more than 4 years. NAc stimulation was tolerated without permanent side effects. Simultaneous recording of local field potentials from the target area and surface electroencephalography while patients performed neuropsychological tasks gave a hint on the pivotal role of the NAc in processing alcohol-related cues. To our knowledge, the data presented here reflect the first attempt to treat alcohol-addicted patients with NAc DBS. Electrical NAc stimulation probably counterbalances the effect of drug-related stimuli triggering involuntarily drug-seeking behavior. Meanwhile, two prospective clinical studies using randomized, double-blind, and crossover stimulation protocols for DBS are underway to corroborate these preliminary results.

For more than a century transition metal sulfides (TMS) have been the anchor of hydro-processing fuels and upgrading bitumen and coal in refineries worldwide. As oil supplies dwindle and environmental laws become more stringent, there is a greater need for cleaner alternative fuels and/or synthetic fuels. The depletion of oil reserves and a rapidly increasing energy demand worldwide, together with the interest to reduce dependence on foreign oil makes alcohol production for fuels and chemicals via the Fischer Tropsch synthesis (FTS) very attractive. The original Fischer-Tropsch (FT) reaction is the heart of all gas-to-liquid technologies; it creates higher alcohols and hydrocarbons from CO/H2 using a metal catalyst. This research focuses on the development of alkali promoted MoS2-based catalysts to investigate an optimal synthesis for their assistance in the production of long chain alcohols (via FTS) for their use as synthetic transportation liquid fuels. Properties of catalytic material are strongly affected by every step of the preparation together with the quality of the raw materials. The choice of a laboratory method for preparing a given catalyst depends on the physical and chemical characteristics desired in the final composition. Characterization methods of K0.3/Cs0.3-MoS2 and K0.3 /Cs0.3-Co0.5MoS2 catalysts have been carried out through Scanning Electron Microscopy (SEM), BET porosity and surface analysis, Transmission Electron Microscopy (TEM) and X-Ray Diffraction (XRD). Various characterization methods have been deployed to correlate FTS products versus crystal and morphological properties of these heterogeneous catalysts. A lab scale gas to liquid system has been developed to evaluate its efficiency in testing FT catalysts for their production of alcohols.

Research has highlighted the significant alcohol symptoms and mental health problems experienced by diagnostic orphans - individuals who experience 1-2 criteria of DSM-IV alcohol dependence but do not meet the criteria for a DSM-IV alcohol use disorder. This study used a sub-sample (n=34827) from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), and formed mutually exclusive groups to compare the self-report retrospective course of diagnostic orphans to individuals with DSM-IV abuse and dependence. Multinomial logistic regressions were conducted to examine the associations between the groups and a range of demographic and clinical variables. Collectively, the findings demonstrate that diagnostic orphans shared similar characteristics to the abuse and dependence groups, but appeared to experience specific comorbid mental health problems. Orphan status has the potential to be a persistent condition and may result in significant dysfunction. In conclusion, diagnostic orphans represent a distinct group that may benefit from cost-effective treatment or intervention, designed to prevent the escalation of alcohol symptoms.

Alcohol continues to occupy a leading position in Europe as a popular substance of abuse. According to WHO sources together with cigarette smoking and obesity, alcohol is a major cause of preventable diseases. Harmful use of alcohol is one of the main factors contributing to premature deaths and disability and has a major impact on public health. The consequences of alcohol use on human health are enormous. Additionally, alcohol use can have harmful effects that do not directly affect person who consumes alcohol (e.g., fetal alcohol syndrome violations that are related to alcohol use, etc.). It is well known that the harmful effects and consequences of alcohol use (e.g., acute and chronic illness, injuries in fights, at the workplace, in traffic, violent behavior, and death) create a great burden for the economic development of society. Persons who have been diagnosed with alcoholism and currently drinking have a less chance to achieve a life insurance cover. On the contrary, recovering alcoholic with a significant abstinent period can get a good life insurance quote. The abstinence of a year or 2 is usually enough for a person to get an average price of life insurance. Furthermore, new consequent relapses could also be considered as potential aggravating factor to accomplish this kind of financial benefits. So far, the research (and interventions) focused on the effects on the population level, such as the increase in taxes, advertising bans, and the implementation of laws that prevent the use of alcohol in traffic. However, it seems that the problem may be viewed at the individual level. The models of the treatment should be designed according to the needs of the individual. These models should incorporate not only the reduction of alcohol intake but also the path to abstinence. The plan should take into account the different (individual) needs for treatment, with regard to the degree of alcohol dependence and health status and also include the needs of the family, community, and broader society.

Rural youth have higher rates of alcohol and tobacco use compared to their urban counterparts. However, the economic dependence of rural communities may differentially influence risk behaviors. While research has shown that adults working in mining have elevated rates of alcohol and tobacco use, the influence of living in a mining community on early adolescent substance use is unknown. Using data from a representative sample of 4,535 middle school students in a state with heavy reliance on mining, we conducted weighted logistic regression to investigate whether community-level mining economic dependence influences rural-urban differences in adolescent alcohol and tobacco use. All models adjusted for sociodemographics, military family involvement, parental monitoring, and length of residence. Over one quarter of the sampled students lived in rural counties and approximately half of these counties met the USDA mining economic typology. After stratifying rural counties by mining and nonmining economic dependence, students in rural mining counties had significantly higher odds of all measures of alcohol use (AORs ranged from 1.83 to 3.99) and tobacco use (AORs ranged from 1.61 to 5.05) compared to students in urban counties. Only use of smokeless tobacco was higher among students in rural nonmining counties. Our findings demonstrate rural-urban disparities in adolescent substance use that are particularly pronounced among youth living in counties with economic dependence on mining. Future research on this subject should include a wider range of community-level factors that may have specific relevance in rural settings to inform the development of population-level interventions. © 2018 National Rural Health Association.
Management of alcohol misuse in Scotland: the role of A&E nurses.
Anderson, S; Eadie, D R; MacKintosh, A M; Haw, S
2001-04-01
Despite national targets to reduce excessive drinking in Scotland, rates have increased dramatically since the mid-eighties. The role of Accident and Emergency (A&E) departments in the management of alcohol misuse is much debated. This postal survey was conducted with senior medical and nursing staff in A&E departments and minor injury units throughout Scotland to examine the prevalence of alcohol-related attendances and staff's attitudes towards identifying and responding to alcohol-related attendances. A 57% response rate was achieved, representing 87% of all A&E institutions in Scotland (n = 84). The results reveal an estimated 1 in 7 attendances in A&E in Scotland are alcohol-related, and 1 in 5 of these result in admission. However, over two-fifths of departments do not routinely screen for, or keep records of, patients who attend with alcohol problems. Intervention is normally limited to a brief dialogue and referral to the patient's GP. Despite considerable barriers, A&E nursing staff express a willingness to assume a preventive role, but acknowledge lack of appropriate training and sources of support. It is concluded that there is scope for developing identification and brief intervention services within A&E. However, such developments are dependent upon alcohol issues assuming a higher priority among senior A&E staff.
Alcohol, appetite and energy balance: is alcohol intake a risk factor for obesity?
Yeomans, Martin R
2010-04-26
The increased recognition that the worldwide increase in incidence of obesity is due to a positive energy balance has lead to a focus on lifestyle choices that may contribute to excess energy intake, including the widespread belief that alcohol intake is a significant risk factor for development of obesity. This brief review examines this issue by contrasting short-term laboratory-based studies of the effects of alcohol on appetite and energy balance and longer-term epidemiological data exploring the relationship between alcohol intake and body weight. Current research clearly shows that energy consumed as alcohol is additive to that from other dietary sources, leading to short-term passive over-consumption of energy when alcohol is consumed. Indeed, alcohol consumed before or with meals tends to increase food intake, probably through enhancing the short-term rewarding effects of food. However, while these data might suggest that alcohol is a risk factor for obesity, epidemiological data suggests that moderate alcohol intake may protect against obesity, particularly in women. In contrast, higher intakes of alcohol in the absence of alcohol dependence may increase the risk of obesity, as may binge-drinking, however these effects may be secondary to personality and habitual beverage preferences.

Genetic research: who is at risk for alcoholism.
Foroud, Tatiana; Edenberg, Howard J; Crabbe, John C
2010-01-01
The National Institute on Alcohol Abuse and Alcoholism (NIAAA) was founded 40 years ago to help elucidate the biological underpinnings of alcohol dependence, including the potential contribution of genetic factors. Twin, adoption, and family studies conclusively demonstrated that genetic factors account for 50 to 60 percent of the variance in risk for developing alcoholism. Case-control studies and linkage analyses have helped identify DNA variants that contribute to increased risk, and the NIAAA-sponsored Collaborative Studies on Genetics of Alcoholism (COGA) has the expressed goal of identifying contributing genes using state-of-the-art genetic technologies. These efforts have ascertained several genes that may contribute to an increased risk of alcoholism, including certain variants encoding alcohol-metabolizing enzymes and neurotransmitter receptors. Genome-wide association studies allowing the analysis of millions of genetic markers located throughout the genome will enable discovery of further candidate genes. In addition to these human studies, genetic animal models of alcohol's effects and alcohol use have greatly advanced our understanding of the genetic basis of alcoholism, resulting in the identification of quantitative trait loci and allowing for targeted manipulation of candidate genes. Novel research approaches-for example, into epigenetic mechanisms of gene regulation-also are under way and undoubtedly will further clarify the genetic basis of alcoholism.
Effects of ALDH2*2 on Alcohol Problem Trajectories of Asian American College Students
Luczak, Susan E.; Yarnell, Lisa M.; Prescott, Carol A.; Myers, Mark G.; Liang, Tiebing; Wall, Tamara L.
2014-01-01
The variant aldehyde dehydrogenase allele, ALDH2*2, consistently has been associated with protection against alcohol dependence, but the mechanism underlying this process is not known. This study examined growth trajectories of alcohol consumption (frequency, average quantity, binge drinking, maximum drinks) and problems over the college years and then tested whether the ALDH2 genotype mediated or moderated the relationship between alcohol consumption and problems. Asian American college students (N = 433) reported on their drinking behavior in their first year of college and then annually for 3 consecutive years. Alcohol consumption and problems increased over the college years for both those with and without ALDH2*2, but having an ALDH2*2 allele was associated with less of an increase in problems over time. A mediation model was supported, with ALDH2*2 group differences in problems fully accounted for by differences in frequency of binge drinking. Findings also supported a moderation hypothesis: All four alcohol consumption variables were significant predictors of subsequent alcohol problems, but these relationships were not as strong in those with ALDH2*2 as in those without ALDH2*2. Our findings suggest that the interplay between ALDH2*2 and drinking-related problems is complex, involving both mediation and moderation processes that reduce the likelihood of developing problems via reduction of heavy drinking as well as by altering the relationship between alcohol consumption and problems. Results of this longitudinal study provide evidence that what seems like a relatively straightforward effect of a diminished ability to metabolize alcohol on drinking behavior is actually dependent on behavior and developmental stage.

Growing evidence supports a role for the central nervous system (CNS) neurotransmitter L-glutamate and its metabotropic receptors (mGluRs) in drug addiction in general and alcohol-use disorders in particular. Alcohol dependence, for instance, has a genetic component, and the recent discovery that variations in the gene coding for mGluR7 modulate alcohol consumption further validates involvement of the L-glutamate system. Consequently, increasing interest emerges in developing L-glutamatergic therapies for the treatment of alcohol abuse and dependence. To this end, we performed a detailed behavioral pharmacology study to investigate the regulation of alcohol consumption and preference following administration of the mGluR7-selective drugs N,N'-dibenzyhydryl-ethane-1,2-diamine dihydrochloride (AMN082) and 6-(4-Methoxyphenyl)-5-methyl-3-(4-pyridinyl)-isoxazolo[4,5-c]pyridin-4(5H)-one hydrochloride (MMPIP). Upon administration of the allosteric agonist AMN082 (10 mg/kg, i.p.) in rats, there was a significant decrease in ethanol consumption and preference, without affecting ethanol blood metabolism. In contrast, mGluR7 blockade with MMPIP (10 mg/kg, i.p.) showed an increase in alcohol intake and reversed AMN082's effect on ethanol consumption and preference. Both mGluR7-directed pharmacological tools had no effect on total fluid intake, taste preference, or on spontaneous locomotor activity. In conclusion, these findings support a specific regulatory role for mGluR7 on alcohol drinking and preference and provide evidence for the use of AMN082-type drugs as potential new treatments for alcohol-use disorders in man. © 2011 The Authors, Addiction Biology © 2011 Society for the Study of Addiction.

Dating aggression has been identified as a priority public health concern. Although alcohol use is a known robust risk factor for dating aggression involvement, such usage is neither necessary nor sufficient for dating aggression involvement. As such, a growing topic of interest is a better understanding of when, and for whom, alcohol use increases risk. A theoretical moderator model posits that associations between alcohol use and dating aggression involvement vary depending on both background (e.g., psychopathology) and situational (e.g., relationship characteristics) risk factors. Alcohol use is thought to be more strongly associated with dating aggression in the context of these other risk factors. Using an intensive longitudinal design, we collected six waves of data spanning 6 months from 120 participants (60 females; M age W1 = 22.44). Alcohol use and relationship risk were both associated with increases in dating aggression involvement. Consistent with a moderator model, interactions emerged between alcohol use and relationship risk for subsequent dating aggression involvement. The findings underscore the importance of alcohol use and relationship risk for the development of intervention and prevention programs.

Fetal Alcohol Syndrome (FAS) refers to the broad spectrum of developmental and behavioral effects caused due to prenatal alcohol exposure (PAE). Wide range of abnormalities vary depending on the amount of alcohol consumed and the period of consumption during gestation. PAE during early stages of pregnancy is very common. However a large number of women continue to consume alcohol even during the second trimester, a critical period for fetal neurogenesis and angiogenesis. Optical coherence tomography (OCT) has shown to be extremely useful in embryonic imaging. Our previous work showed that OCT is capable of quantitative assessment of ventriculomegaly caused by maternal alcohol consumption. Although structural changes and changes in blood flow in the fetal brain after maternal alcohol consumption have been studied, acute vasculature changes are not well documented. Speckle variance OCT (SVOCT), is a functional extension of OCT that has been used to study vasculature development in embryos. We use SVOCT, to detect vasculature changes in the embryonic brain in utero, minutes after maternal alcohol consumption.

To understand the mental health status of Central American migrant men travelling through Mexico to the U.S., we analysed the association between migration-related circumstances/stressors and psychological disorders. In-person interviews and a psychiatric assessment were conducted in 2010 and 2014 with 360 primarily Honduran transmigrant young adult males. The interviews were conducted at three Casas del Migrante (or migrant safe houses) in the migration-corridor cities of Monterrey, and Guadalupe, Nuevo Leon; and Saltillo, Coahuila. The results indicated high levels of migration-related stressors including abuse and a high prevalence of major depressive episodes (MDEs), alcohol dependency, and alcohol abuse. Nested logistic regression models were used to separately predict MDEs, alcohol dependency, and alcohol abuse, assessing their association with migration experiences and socio-demographic characteristics. Logistic regression models showed that characteristics surrounding migration (experiencing abuse, migration duration, and attempts) are predictive of depression. Alcohol dependency and abuse were both associated with marital status and having family/friends in the intended U.S. destination, while the number of migration attempts also predicted alcohol dependency. The results provide needed information on the association between transit migration through Mexico to the U.S. among unauthorised Central American men and major depressive disorder and alcohol abuse and dependency.

To examine the effect of physical activity on risk of developing alcohol use disorders in a large prospective cohort study with focus on leisure-time physical activity. Data came from the four examinations of the Copenhagen City Heart Study (CCHS), performed in 1976-1978, 1981-1983, 1991-1994 and 2001-2003. Information on physical activity (classified as Moderate/high, low or sedentary) and covariates was obtained through self-administered questionnaires, and information on alcohol use disorders was obtained from the Danish Hospital Discharge Register, the Danish Psychiatric Central Research Register and the Winalco database. In total, 18,359 people participated in the study, a mean follow-up time of 20.9 years. Cox proportional hazards model with delayed entry was used. Models were adjusted for available covariates (age, smoking habits, alcohol intake, education, income and cohabitation status) including updated time-dependent variables whenever possible. A low or moderate/high leisure-time physical activity was associated with almost half the risk of developing alcohol use disorder compared with a sedentary leisure-time physical activity. This translates into a 1.5- to 2-fold increased risk of developing alcohol use disorder (Hazard ratios for men 1.64; 95% CI 1.29-2.10 and women 1.45; 1.01-2.09) in individuals with a sedentary leisure-time physical activity, compared with a moderate to high level. However, when stratifying by presence of other psychiatric disorders, no association was observed in women with psychiatric comorbidity. Residual confounding may have been present in this study, especially according to rough measures of income and education. In both men and women, being sedentary in leisure time was a risk factor for developing an alcohol use disorder. © The Author 2014. Medical Council on Alcohol and Oxford University Press.

Endogenous opioids are implicated in the mechanism of action of alcohol and alcohol affects opioids in a number of brain areas, although little is known about alcohol's effects on opioids in the adolescent brain. One concern, in particular when studying young animals, is that alcohol intake models often are based on single housing that may result in alcohol effects confounded by the lack of social interactions. The aim of this study was to investigate short- and long-term alcohol effects on opioids and the influence of housing conditions on these effects. In the first part, opioid peptide levels were measured after one 24-hour session of single housing and 2-hour voluntary alcohol intake in adolescent and adult rats. In the second part, a model with a cage divider inserted during 2-hour drinking sessions was tested and the effects on opioids were examined after 6 weeks of adolescent voluntary intake in single-and pair-housed rats, respectively. The effects of single housing were age specific and affected Met-enkephalin-Arg(6) Phe(7) (MEAP) in particular. In adolescent rats, it was difficult to distinguish between effects induced by alcohol and single housing, whereas alcohol-specific effects were seen in dynorphin B (DYNB), beta-endorphin (BEND), and MEAP levels in adults. Voluntary drinking affected several brain areas and the majority of alcohol-induced effects were not dependent on housing. However, alcohol effects on DYNB and BEND in the amygdala were dependent on housing. Housing alone affected MEAP in the cingulate cortex. Age-specific housing- and alcohol-induced effects on opioids were found. In addition, prolonged voluntary alcohol intake under different housing conditions produced several alcohol-induced effects independent of housing. However, housing-dependent effects were found in areas implicated in stress, emotionality, and alcohol use disorder. Housing condition and age may therefore affect the reasons and underlying mechanisms for drinking and could potentially affect the outcome of a number of end points in research on alcohol intake.

Dual diagnosis is the coexistence of an addictive disorder and another mental disorder. The objective is to estimate cravings and self-reported quality of life in a sample of patients with alcoholic dependence, with or without dual pathology, who attend an outpatient treatment centre. A cross-sectional study of 112 patients (56 dual and 56 non-dual), diagnosed with alcohol dependence according to DSM-IV-TR. The presence of cravings is determined by the Multidimensional Alcohol Craving Scale and quality of life through the SF-36 Health Questionnaire. There are no statistically significant differences in cravings in either subgroup; the latter tend to refer to lower alcohol cravings than non-dual patients. The dual patients have a worse quality of life in all categories evaluated, highlighting a worse quality of life in the categories: social function, emotional role, vitality and general health. Females present a lower quality of life emphasising those of social function and emotional role. No differences were detected in relation to cravings between the 2 groups. In order to perform a correct clinical and therapeutic approach for patients with alcohol dependence, we should consider focusing on the evaluation of cravings and quality of life. In order to perform a correct clinical and therapeutic approach for patients with alcohol dependence, it is necessary to consider cravings and quality of life, since these parameters are important for the evaluation of patients with alcohol dependence.

Cognitive control dysfunction has been identified in dependent alcohol users and implicated in the transition from abuse to dependence, although evidence of dyscontrol in chronic but non-dependent 'harmful' alcohol abusers is mixed. The current study examined harmful alcohol users response inhibition over rewarding stimuli in the presence of monetary reward and punishment, to determine whether changes in sensitivity to these factors, noted in imaging studies of dependent users, influences impulse control. Harmful (n=30) and non-hazardous (n=55) alcohol users were administered a Monetary Incentive Go/No-go task that required participants to inhibit a prepotent motor response associated with reward. Harmful alcohol users showed a significantly poorer ability to withhold their impulse for a rewarding stimulus in the presence of immediate monetary punishment for failure, while retaining equivalent response inhibition performance under neutral conditions (associated with neither monetary loss or gain), and significantly better performance under delayed reward conditions. The results of the present study suggest that non-dependent alcohol abusers have altered sensitivity to reward and punishment that influences their impulse control for reward, in the absence of gross dyscontrol that is consistent with past findings in which such performance contingencies were not used. The ability of delayed monetary reward, but not punishment, to increase sustained impulse control in this sample has implications for the mechanism that might underlie the transition from alcohol abuse to dependence, as well as intervention strategies aimed at preventing this transition.

We have used a translational Convergent Functional Genomics (CFG) approach to discover genes involved in alcoholism, by gene-level integration of genome-wide association study (GWAS) data from a German alcohol dependence cohort with other genetic and gene expression data, from human and animal model studies, similar to our previous work in bipolar disorder and schizophrenia. A panel of all the nominally significant P-value SNPs in the top candidate genes discovered by CFG (n=135 genes, 713 SNPs) was used to generate a genetic risk prediction score (GRPS), which showed a trend towards significance (P=0.053) in separating alcohol dependent individuals from controls in an independent German test cohort. We then validated and prioritized our top findings from this discovery work, and subsequently tested them in three independent cohorts, from two continents. In order to validate and prioritize the key genes that drive behavior without some of the pleiotropic environmental confounds present in humans, we used a stress-reactive animal model of alcoholism developed by our group, the D-box binding protein (DBP) knockout mouse, consistent with the surfeit of stress theory of addiction proposed by Koob and colleagues. A much smaller panel (n=11 genes, 66 SNPs) of the top CFG-discovered genes for alcoholism, cross-validated and prioritized by this stress-reactive animal model showed better predictive ability in the independent German test cohort (P=0.041). The top CFG scoring gene for alcoholism from the initial discovery step, synuclein alpha (SNCA) remained the top gene after the stress-reactive animal model cross-validation. We also tested this small panel of genes in two other independent test cohorts from the United States, one with alcohol dependence (P=0.00012) and one with alcohol abuse (a less severe form of alcoholism; P=0.0094). SNCA by itself was able to separate alcoholics from controls in the alcohol-dependent cohort (P=0.000013) and the alcohol abuse cohort (P=0.023). So did eight other genes from the panel of 11 genes taken individually, albeit to a lesser extent and/or less broadly across cohorts. SNCA, GRM3 and MBP survived strict Bonferroni correction for multiple comparisons. Taken together, these results suggest that our stress-reactive DBP animal model helped to validate and prioritize from the CFG-discovered genes some of the key behaviorally relevant genes for alcoholism. These genes fall into a series of biological pathways involved in signal transduction, transmission of nerve impulse (including myelination) and cocaine addiction. Overall, our work provides leads towards a better understanding of illness, diagnostics and therapeutics, including treatment with omega-3 fatty acids. We also examined the overlap between the top candidate genes for alcoholism from this work and the top candidate genes for bipolar disorder, schizophrenia, anxiety from previous CFG analyses conducted by us, as well as cross-tested genetic risk predictions. This revealed the significant genetic overlap with other major psychiatric disorder domains, providing a basis for comorbidity and dual diagnosis, and placing alcohol use in the broader context of modulating the mental landscape.

Chronic consumption of alcohol represents one of the greatest health and socioeconomic problems worldwide. We report on a 54-year-old patient with a severe anxiety disorder and secondary depressive disorder in whom bilateral deep brain stimulation (DBS) of the nucleus accumbens was carried out. Despite the absence of desired improvement in his primary disorder, we observed a remarkable although not primarily intended alleviation of the patient’s comorbid alcohol dependency. Our case report demonstrates the extremely effective treatment of alcohol dependency by means of DBS of the nucleus accumbens and may reveal new prospects in overcoming therapy resistance in dependencies in general.

Hepatitis C virus (HCV) and alcoholic liver disease (ALD), either alone or in combination, count for more than two thirds of all liver diseases in the Western world. There is no safe level of drinking in HCV-infected patients and the most effective goal for these patients is total abstinence. Baclofen, a GABAB receptor agonist, represents a promising pharmacotherapy for alcohol dependence (AD). Previously, we performed a randomized clinical trial (RCT), which demonstrated the safety and efficacy of baclofen in patients affected by AD and cirrhosis. The goal of this post-hoc analysis was to explore baclofen's effect in a subgroup of alcohol-dependent HCV-infected cirrhotic patients. Any patient with HCV infection was selected for this analysis. Among the 84 subjects randomized in the main trial, 24 alcohol-dependent cirrhotic patients had a HCV infection; 12 received baclofen 10mg t.i.d. and 12 received placebo for 12-weeks. With respect to the placebo group (3/12, 25.0%), a significantly higher number of patients who achieved and maintained total alcohol abstinence was found in the baclofen group (10/12, 83.3%; p=0.0123). Furthermore, in the baclofen group, compared to placebo, there was a significantly higher increase in albumin values from baseline (p=0.0132) and a trend toward a significant reduction in INR levels from baseline (p=0.0716). In conclusion, baclofen was safe and significantly more effective than placebo in promoting alcohol abstinence, and improving some LFTs (i.e. albumin, INR) in alcohol-dependent HCV-infected cirrhotic patients. Baclofen may represent a clinically relevant alcohol pharmacotherapy for these patients. PMID:22244707

Although substance use is associated with reduced educational attainment, this association may be owing to common risk factors such as socioeconomic disadvantage. We tested whether alcohol, nicotine, and illicit drug use and dependence were associated with lifetime educational attainment after controlling for familial background characteristics. Data were from a 1987 questionnaire and a 1992 telephone diagnostic interview of 6,242 male twins (n = 3,121 pairs; mean age = 41.9 years in 1992) who served in the U.S. military during the Vietnam era and therefore, were eligible for educational benefits after military service. Reduced educational attainment (<16 years) was examined in twin pairs discordant for substance use history. Substance use and dependence risk factors assessed were early alcohol and cannabis use, daily nicotine use, lifetime cannabis use, and alcohol, nicotine, cannabis, and any illicit drug dependence. Three significant differences were observed between at-risk twins and their cotwins: Compared to their low-risk cotwins, likelihood of completing <16 years of education was significantly increased for the following: (i) twins who used alcohol before age 18 (adjusted OR = 1.44; 95% CI: 1.02 to 2.05), (ii) twins with a lifetime alcohol dependence diagnosis (adjusted OR = 1.76; 95% CI: 1.27 to 2.44), and (iii) twins who had used nicotine daily for 30 or more days (adjusted OR = 2.54, 95% CI: 1.55 to 4.17). However, no differences in education were observed among twin pairs discordant for cannabis initiation, early cannabis use, or cannabis, nicotine, or any illicit drug dependence. Even in a veteran population with access to military educational benefits, early alcohol use, alcohol dependence, and daily nicotine use remained significantly associated with years of education after controlling for shared familial contributions to educational attainment. The association between other substances and educational attainment was explained by familial factors common to these substance use phenotypes and adult educational attainment.

Factors related to comorbid versus only substance disorders are essential to understanding and treating these complex problems. Medical records of sixty-nine inpatients at a private rehabilitation hospital in Southern California were reviewed to determine the associations between personal history factors and (1) comorbid psychiatric and substance abuse disorders and (2) participant's self-assessed progress in treatment. Results revealed significant differences between dual diagnosis patients (alcohol abuse/dependence and an affective disorder) and alcohol abuse/dependence only in regard to gender, previous diagnosis, length of illness, suicide attempts, psychotropic medication history, maternal emotional, physical and sexual abuse, paternal abuse, legal difficulties, and psychosocial stressors. No significant differences between substance abusing patients and dually diagnosed patients were found in terms of self-assessment of progress in treatment. Significant correlations were found between self-assessed progress in treatment and major depression (versus bipolar disorder), use of psychotropic medication, and less abuse from mother or primary caretaker. Identification of these personal history factors may be useful in developing and implementing treatment plans.

Using the quantum chemical semi-empirical PM3 method it is shown that aliphatic alcohols favor the spontaneous clusterization of vaporous alkanes at the water surface due to the change of adsorption from the barrier to non-barrier mechanism. A theoretical model of the non-barrier mechanism for monolayer formation is developed. In the framework of this model alcohols (or any other surfactants) act as 'floats', which interact with alkane molecules of the vapor phase using their hydrophobic part, whereas the hydrophilic part is immersed into the water phase. This results in a significant increase of contact effectiveness of alkanes with the interface during the adsorption and film formation. The obtained results are in good agreement with the existing experimental data. To test the model the thermodynamic and structural parameters of formation and clusterization are calculated for vaporous alkanes C(n)H(2n+2) (n(CH3) = 6-16) at the water surface in the presence of aliphatic alcohols C(n)H(2n+1)OH (n(OH) = 8-16) at 298 K. It is shown that the values of clusterization enthalpy, entropy and Gibbs' energy per one monomer of the cluster depend on the chain lengths of corresponding alcohols and alkanes, the alcohol molar fraction in the monolayers formed, and the shift of the alkane molecules with respect to the alcohol molecules Δn. Two possible competitive structures of mixed 2D film alkane-alcohol are considered: 2D films 1 with single alcohol molecules enclosed by alkane molecules (the alcohols do not form domains) and 2D films 2 that contain alcohol domains enclosed by alkane molecules. The formation of the alkane films of the first type is nearly independent of the surfactant type present at the interface, but depends on their molar fraction in the monolayer formed and the chain length of the compounds participating in the clusterization, whereas for the formation of the films of the second type the interaction between the hydrophilic parts of the surfactant is essential and different for various types of amphiphilic compounds. The energetic preference of the film formation of both types depends significantly on the chain length of compounds. The surfactant concentration (in the range of X = 0-10%) exerts a slight influence on the process of film formation.

We previously demonstrated that prodynorphin (PDYN) haplotypes and single nucleotide polymorphism (SNP) rs2281285 are associated with alcohol dependence and the propensity to drink in negative emotional states, and recent studies suggest that PDYN gene effects on substance dependence risk may be sex-related. We examined sex-dependent associations of PDYN variation with alcohol dependence and related phenotypes, including negative craving, time until relapse after treatment and the length of sobriety episodes before seeking treatment, in discovery and validation cohorts of European ancestry. We found a significant haplotype-by-sex interaction (p = 0.03), suggesting association with alcohol dependence in males (p = 1E-4) but not females. The rs2281285 G allele increased risk for alcohol dependence in males in the discovery cohort (OR = 1.49, p = 0.002), with a similar trend in the validation cohort (OR = 1.35, p = 0.086). However, rs2281285 showed a trend towards association with increased negative craving in females in both the discovery (beta = 10.16, p = 0.045) and validation samples (OR = 7.11, p = 0.066). In the discovery cohort, rs2281285 was associated with time until relapse after treatment in females (HR = 1.72, p = 0.037); in the validation cohort, it was associated with increased length of sobriety episodes before treatment in males (beta = 13.49, p = 0.001). Our findings suggest that sex-dependent effects of PDYN variants in alcohol dependence are phenotype-specific. PMID:26502829

Background Previous studies have shown cultural variations in normative drinking and furthermore, in the quantity and frequency of drinking related to alcohol use disorders. Aim The main goal of this study is to characterize alcohol drinking patterns in Argentinean Emergency Department patients, and secondly, to explore the association between those drinking patterns and DSM-IV alcohol use disorders. Method Data were collected from a probability sample of patients admitted to the Emergency Department of a large public hospital in Mar del Plata, Argentina. Data analyzed here pertain to those who reported consuming at least one drink during the last twelve months (n=529). A factor analysis of multiple correspondences and a hierarchic classification were performed. For the factor analysis, usual quantity and frequency of drinking (for the last 12 months) were considered active variables; number of DSM-IV dependence criteria met, positive or negative diagnostic status for abuse, positive or negative diagnostic status for dependence (both for the last 12 months), and socio-demographic characteristics (age, gender and economic level) were considered illustrative variables. Results The first five factorial axes were retained, accounting for 88% of the total variance. Hierarchic classification resulted in six distinctive classes of drinking patterns. Two patterns were associated with a positive diagnosis of abuse and dependence, respectively. One, drinking between 4 and 6 drinks per occasion mostly on a weekly basis, was associated with a diagnosis of abuse; this pattern was also associated with meeting one or two dependence criteria (dependence orphans). The other, drinking 7 or more drinks per occasion, was associated with a diagnosis of dependence, and also with a diagnostic orphan condition. This class, composed primarily of males, was not characterized by any particular frequency of drinking. The other four drinking patterns were not associated with a positive diagnosis of an alcohol use disorder. Two of them were characterized by drinking low quantities with a low frequency (either monthly or yearly). Participants in both of these classes tended to be female. The other two patterns were characterized by drinking less than 3 drinks per occasion, either daily or weekly: the former associated with being older than 35 years, and the later with no distinctive socio-demographic characteristics. Conclusions Results demonstrated six distinct drinking patterns, two of them related to a positive diagnosis of an alcohol use disorder. Our findings support previous research indicating that dependence orphans share some characteristics with abuse and dependence cases. Given the lack of similar studies in the region, these findings, although descriptive, enrich the knowledge of alcohol use disorders in the regional context. Furthermore, they may contribute to the development of local drinking guidelines and prevention strategies. PMID:22984352

Problems associated with alcohol abuse are recognised by the World Health Organization as a major health issue, which according to most recent estimations is responsible for 1.4% of the total world burden of morbidity and has been proven to increase mortality risk by 50%. Because of the size and severity of the problem, early detection is very important. This requires easy to use and specific tools. One of these is the Alcohol Use Disorders Identification Test (AUDIT). This study aims to standardise the questionnaire in a Greek population. AUDIT was translated and back-translated from its original language by two English-speaking psychiatrists. The tool contains 10 questions. A score >or= 11 is an indication of serious abuse/dependence. In the study, 218 subjects took part: 128 were males and 90 females. The average age was 40.71 years (+/- 11.34). From the 218 individuals, 109 (75 male, 34 female) fulfilled the criteria for alcohol dependence according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), and presented requesting admission; 109 subjects (53 male, 56 female) were healthy controls. Internal reliability (Cronbach alpha) was 0.80 for the controls and 0.80 for the alcohol-dependent individuals. Controls had significantly lower average scores (t test P < 0.001) when compared to the alcoholics. The questionnaire's sensitivity for scores >8 was 0.98 and its specificity was 0.94 for the same score. For the alcohol-dependent sample 3% scored as false negatives and from the control group 1.8% scored false positives. In the alcohol-dependent sample there was no difference between males and females in their average scores (t test P > 0.05). The Greek version of AUDIT has increased internal reliability and validity. It detects 97% of the alcohol-dependent individuals and has a high sensitivity and specificity. AUDIT is easy to use, quick and reliable and can be very useful in detection alcohol problems in sensitive populations.

Better knowledge of the factors that have an impact on pathways to mental health care may contribute greatly to organizing optimum health-care delivery. However, surveillance systems concerning alcohol problems in the French general population are suboptimal. The objectives of this study were to investigate: 1) the prevalence of mental health-care seeking in individuals with alcohol abuse/dependence in France, 2) which category of medical practitioner was consulted, and 3) psychological and socio-environmental factors associated with mental health-care seeking. A total sample of 22,138 individuals was interviewed in a telephone survey. Individual data on alcohol dependence/abuse and other mental health disorders were collected using the Composite International Diagnosis Interview - short form. Mental health-care seeking was assessed, together with data on living conditions, deprivation, and self-reported drinking problems. Only respondents meeting criteria for alcohol dependence/abuse were included in analyses. Less than half of the 722 respondents with alcohol abuse/dependence had sought mental health care in the preceding 12 months, of whom 90.5% consulted their general practitioner (GP) (56.1%), or both a general practitioner and a psychiatrist (34.4%). Mental health-care seeking was associated with female sex, previous alcohol discussion with a doctor, and the presence of psychiatric comorbidities arising in the preceding 12 months. Living environment, socio-economic status, or self-reported drinking problems had no influence. A minority of people with alcohol abuse/dependence sought mental health care, mainly in relation to psychiatric comorbidities. In addition, most people consulting a GP were not referred to a psychiatrist. However, social deprivation and living in rural areas did not hinder mental health-care seeking among respondents. Adequate protocols to treat alcohol disorders could be implemented among private health-care providers to improve management of alcohol problems in France. Copyright © 2016 Elsevier Inc.

Factors that confer predisposition and vulnerability for alcoholism and other substance abuse disorders may be described usefully within the gene-environment interplay framework. Thus, it is postulated that heritability provides a major contribution not only to alcohol but also to other substances of abuse. Studies of evoked potential amplitude reduction have provided a highly suitable and testable method for the assessment of both environmentally-determined and heritable characteristics pertaining to substance use and dependence. The different personal attributes that may co-exist with parental influence or exist in a shared, monozygotic relationship contribute to the final expression of addiction. In this connection, it appears that personality disorders are highly prevalent co-morbid conditions among addicted individuals, and, this co-morbidity is likely to be accounted for by multiple complex etiological relationships, not least in adolescent individuals. Co-morbidity associated with deficient executive functioning may be observed too in alcohol-related aggressiveness and crimes of violence. The successful intervention into alcohol dependence and craving brought about by baclofen in both human and animal studies elucidates glutamatergic mechanisms in alcoholism whereas the role of the dopamine transporter, in conjunction with both the noradrenergic and serotonergic transporters, are implicated in cocaine dependence and craving. The role of the cannabinoids in ontogeny through an influence upon the expression of key genes for the development of neurotransmitter systems must be considered. Finally, the particular form of behaviour/characteristic outcome due to childhood circumstance may lie with biological, gene-based determinants, for example individual characteristics of monoamine oxidase (MAO) activity levels, thereby rendering simple predictive measures both redundant and misguiding.

Impaired inhibitory control contributes to the development, maintenance, and relapse of alcohol-dependence, but the neural correlates of this deficit are still unclear. Because inhibitory control has been labeled as an executive function, most studies have focused on prefrontal areas, overlooking the contribution of more "primary" structures, such as the motor system. Yet, appropriate neural inhibition of the motor output pathway has emerged as a central aspect of healthy behavior. Here, we tested the hypothesis that this motor inhibition is altered in alcohol-dependence. Neural inhibitory measures of motor activity were obtained in 20 detoxified alcohol-dependent (AD) patients and 20 matched healthy subjects, using a standard transcranial magnetic stimulation procedure whereby motor-evoked potentials (MEPs) are elicited in a choice reaction time task. Moreover, behavioral inhibition and trait impulsivity were evaluated in all participants. Finally, the relapse status of patients was assessed 1 year after the experiment. As expected, AD patients displayed poorer behavioral inhibition and higher trait impulsivity than controls. More importantly, the MEP data revealed a considerable shortage of neural motor inhibition in AD patients. Interestingly, this neural defect was strongest in the patients who ended up relapsing during the year following the experiment. Our data suggest a strong motor component in the neural correlates of altered inhibitory control in AD patients. They also highlight an intriguing relationship with relapse and the perspective of a new biomarker to follow strategies aiming at reducing relapse in AD patients.

Several studies have identified genes associated with alcohol use disorders, but the variation in each of these genes explains only a small portion of the genetic vulnerability. The goal of the present study was to perform a genome-wide association study (GWAS) in extended families from the Collaborative Study on the Genetics of Alcoholism (COGA) to identify novel genes affecting risk for alcohol dependence. To maximize the power of the extended family design we used a quantitative endophenotype, measured in all individuals: number of alcohol dependence symptoms endorsed (symptom count). Secondary analyses were performed to determine if the single nucleotide polymorphisms (SNPs) associated with symptom count were also associated with the dichotomous phenotype, DSM-IV alcohol dependence. This family-based GWAS identified SNPs in C15orf53 that are strongly associated with DSM-IV alcohol (p=4.5×10−8, inflation corrected p=9.4×10−7). Results with DSM-IV alcohol dependence in the regions of interest support our findings with symptom count, though the associations were less significant. Attempted replications of the most promising association results were conducted in two independent samples: non-overlapping subjects from the Study of Addiction: Genes and Environment (SAGE) and the Australian twin-family study of alcohol use disorders (OZALC). Nominal association of C15orf53 with symptom count was observed in SAGE. The variant that showed strongest association with symptom count, rs12912251 and its highly correlated variants (D′=1, r2≥ 0.95), has previously been associated with risk for bipolar disorder.

In this study, we aimed to search cognitive, behavioral and psychopathological differences between children of fathers with alcohol dependency and children of fathers without alcohol dependency. Forty-six children of 34 alcoholic fathers and 36 children of 34 non-alcoholic fathers, between the ages of 6 and 16 years were evaluated. Two groups were matched with each other on the basis of socioeconomic level of family, age and gender of children. All children were screened for psychiatric disorders according to DSM-IV criterias by using the Schedule for Affective Disorders and Schizophrenia for School Aged Children, Present and Lifetime Version (K-SADS-PL). The mothers and teachers completed the Child Behavior Checklist, Teacher Report Form and Conners Parents/Teachers Rating Scales. Furthermore, Wecshler Inteligence Scale for Children-Revised (WISC-R) and Bender Gestalt Visual Motor Coordination test were applied to all children. The mothers completed Symptom Checklist-90-Revised (SCL-90-R). The findings of this research indicated that children of alcoholic fathers had a higher incidence of psychopathology. Teacher Report Form and Conners Teachers Rating Scale scores were higher in research group. It was also found that mothers in research group had higher level of psychiatric symptoms in SCL-90-R. Alcohol dependent patients are an easily available group for clinicians. It can be more realistic to treat alcohol dependency as a family disease because of associated psychiatric problems in children and mothers. In addition to alcohol dependent fathers, including mothers and children in the psychiatric assessment and treatment plans may become a preventive step for the child.

Rationale Quetiapine has been shown to be a promising medication for the treatment of alcoholism. As an atypical antipsychotic medication with antagonist activity at D1 and D2, 5-HT1A and 5-HT2A, H1 and α1 and α2 receptors, quetiapine has been found to decrease impulsivity in other psychiatric disorders but its effects on impulsivity have not been studied in alcohol dependent patients. Objective This study seeks to test the effects of quetiapine on a specific dimension of impulsivity, namely response inhibition. This pilot study seeks to further elucidate the mechanisms of action of quetiapine for alcohol use disorders. Method A total of 20 non-treatment seeking alcohol dependent individuals were randomized to one of the following conditions in a double-blind, placebo-controlled design: (1) quetiapine (400 mg/day); or (2) matched placebo. Participants completed two counterbalanced intravenous placebo-alcohol administration sessions as well as behavioral measure of response inhibition (i.e. stop signal task) pre and post placebo-alcohol administration sessions. Results Analyses revealed a significant effect of quetiapine in improving response inhibition as measured by the stop signal task. These results provide preliminary evidence suggesting that quetiapine improves response inhibition in alcohol dependent patients, as compared to placebo. Conclusion This pilot study contributes a novel putative mechanism of action of quetiapine in alcoholism, namely an improvement in response inhibition. PMID:22037407

Aims: Growing data reveals deficits in perception, understanding and regulation of emotions in alcohol dependence (AD). The study objective was to explore the relationships between emotional processing, drinking history and relapse in a clinical sample of alcohol-dependent patients. Methods: A group of 80 inpatients entering an alcohol treatment program in Warsaw, Poland was recruited and assessed at baseline and follow-up after 12 months. Baseline information about demographics, psychopathological symptoms, personality and severity of alcohol problems was obtained. The Schutte Self-Report Emotional Intelligence (EI) Test and Toronto Alexithymia Scale (TAS) were utilized for emotional processing assessment. Follow-up information contained data on drinking alcohol during the last month. Results: At baseline assessment, the duration of alcohol drinking was associated with lower ability to utilize emotions. Patients reporting more difficulties with describing feelings drank more during their last episode of heavy drinking, and had a longer duration of intensive alcohol use. A longer duration of the last episode of heavy drinking was associated with more problems identifying and regulating emotions. Poor utilization of emotions and high severity of depressive symptoms contributed to higher rates of drinking at follow-up. Conclusions: These results underline the importance of systematic identification of discrete emotional problems and dynamics related to AD. This knowledge has implications for treatment. Psychotherapeutic interventions to improve emotional skills could be utilized in treatment of alcohol-dependent patients. PMID:25543129

Background Peripheral immune system cytokines may play an integral role in underlying sensitized stress response and alcohol craving during early withdrawal. To date, the nature of these immune changes during early abstinence have not been examined. Methods Thirty-nine early abstinent, treatment-seeking alcohol dependent individuals and 46 socially drinking controls were exposed to three guided imageries: stress, alcohol cue and neutral. These were presented randomly across consecutive days. Plasma measures of tumor necrosis factor alpha (TNFα), tumor necrosis factor receptor 1 (TNFR1), interleukin-6 (IL-6), and interleukin-10 (IL-10), were collected at baseline, immediately after imagery and at various recovery time-points. Ratings of alcohol craving, negative mood and anxiety were also obtained at the same time-points. Results The alcohol group demonstrated decreased basal IL-10 compared with controls particularly following exposure to alcohol cue. They also showed a dampened TNFα and TNFR1 response to stress and cue, respectively, and a generalized suppression of IL-6. In the alcohol group, these immune system adaptations occurred alongside significant elevations in anxiety, negative mood and alcohol craving. Conclusions Findings demonstrate that broad immuno-suppression is still observed in alcohol dependent individuals after three weeks of abstinence and may be linked to motivation for alcohol.

Trait Mindfulness Predicts Attentional and Autonomic Regulation of Alcohol Cue-Reactivity
Garland, Eric L.
2013-01-01
Background The trait of mindfulness varies among meditation-naïve individuals and is associated with attentional and autonomic regulation, two neurocognitive functions that become impaired in addiction. It was hypothesized that alcohol dependent inpatients with comparatively high levels of trait mindfulness would exhibit significant autonomic recovery from stress-primed alcohol cues mediated by greater attentional disengagement from such cues. Methods 58 alcohol dependent inpatients participated in affect-modulated psychophysiological cue-reactivity protocol and a spatial cueing task designed to assess alcohol attentional bias (AB). Associations between trait mindfulness, alcohol AB, and an index of autonomic activity, high-frequency heart rate variability (HFHRV), were examined via multivariate path analysis. Results Higher trait mindfulness was significantly associated with less difficulty resisting the urge to drink and greater HFHRV recovery from stress-primed alcohol cues. After statistically controlling for the correlation of mindfulness and perceived difficulty resisting drinking urges, the association between mindfulness and HFHRV recovery was partially mediated by attentional disengagement from alcohol cues (model R2 = .30). Discussion Alcohol dependent inpatients higher in mindfulness are better able to disengage attention from alcohol cues, which in turn predicts the degree of HFHRV recovery from such cues. Trait mindfulness may index cognitive control over appetitive responses reflected in superior attentional and autonomic regulation of stress-primed alcohol cue-reactivity. PMID:23976814

Impulsivity is a hallmark of addictive behaviors. Addicts' weakened inhibition of irrelevant prepotent responses is commonly thought to explain this association. However, inhibition is not a unitary mechanism. This study investigated the efficiency of overcoming competition due to irrelevant responses (i.e., inhibition of a prepotent response) and overcoming competition in memory (i.e., resistance to proactive interference) in sober and recently detoxified alcohol-dependent individuals. Three cognitive tasks assessing the inhibition of a prepotent response (Hayling task, anti-saccade task and Stroop task) and two tasks tapping into the capacity to resist proactive interference (cued recall, Brown-Peterson variant) were administered to 30 non-amnesic recently detoxified alcohol-dependent individuals and 30 matched healthy participants without alcohol dependency. In addition, possible confounds such as verbal updating in working memory was assessed. Alcohol-dependent subjects performed worse than healthy participants on the three cognitive tasks assessing the inhibition of irrelevant prepotent responses but group performance was similar in the tasks assessing overcoming proactive interference in memory, updating of working memory and abstract reasoning. These findings suggest that alcohol-dependence is mainly associated with impaired capacity to intentionally suppress irrelevant prepotent response information. Control of proactive interference from memory is preserved. Theoretical and clinical implications are discussed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Hispanics are heterogeneous in national origin, evidenced by wide ranges of alcohol abuse and dependence rates across different Hispanic national groups. This paper examines associations between 12-month rates of DSM-IV alcohol abuse and dependence with birthplace and acculturation. The 2006 Hispanic Americans Baseline Alcohol Survey, using a multistage cluster sample design, interviewed 5,224 adults (18+ years) in five selected U.S. metropolitan areas: Miami, New York, Philadelphia, Houston, and Los Angeles. Comprehensive data on drinking behavior were collected and the analyses include bivariate and multivariate regression techniques. Alcohol abuse and dependence rates were higher among U.S.-born Puerto Ricans and South/Central Americans compared to their foreign-born counterparts, while no such differences were found for Cuban and Mexican Americans. Overall, those with higher acculturation report higher rates of abuse and dependence (statistically significant only for abuse among Puerto Ricans). Risk factors for abuse include being male and being in the high acculturation group. Risk factors for dependence include being male, being Puerto Rican or Mexican American, having less than a college education, and being U.S.-born. Hispanics were found to share several common risk factors with the larger U.S. population for abuse and dependence, such as male gender, lower education, and lower income. PMID:18945554

Alcohol-related cues acquire incentive salience through Pavlovian conditioning and then can markedly affect instrumental behavior of alcohol-dependent patients to promote relapse. However, it is unclear whether similar effects occur with alcohol-unrelated cues. We tested 116 early-abstinent alcohol-dependent patients and 91 healthy controls who completed a delay discounting task to assess choice impulsivity, and a Pavlovian-to-instrumental transfer (PIT) paradigm employing both alcohol-unrelated and alcohol-related stimuli. To modify instrumental choice behavior, we tiled the background of the computer screen either with conditioned stimuli (CS) previously generated by pairing abstract pictures with pictures indicating monetary gains or losses, or with pictures displaying alcohol or water beverages. CS paired to money gains and losses affected instrumental choices differently. This PIT effect was significantly more pronounced in patients compared to controls, and the group difference was mainly driven by highly impulsive patients. The PIT effect was particularly strong in trials in which the instrumental stimulus required inhibition of instrumental response behavior and the background CS was associated to monetary gains. Under that condition, patients performed inappropriate approach behavior, contrary to their previously formed behavioral intention. Surprisingly, the effect of alcohol and water pictures as background stimuli resembled that of aversive and appetitive CS, respectively. These findings suggest that positively valenced background CS can provoke dysfunctional instrumental approach behavior in impulsive alcohol-dependent patients. Consequently, in real life they might be easily seduced by environmental cues to engage in actions thwarting their long-term goals. Such behaviors may include, but are not limited to, approaching alcohol.

Gabapentin, a drug used in the treatment of epileptic seizures and neuropathic pain, has shown efficacy in the treatment of alcohol dependence. Moreover, given that gabapentin is used in the general population (e.g., non-dependent individuals, social drinkers), we sought to utilize preclinical assessments to examine the effects of gabapentin on sensitivity to moderate alcohol doses and alcohol self-administration in rats with a history of moderate drinking. To this end, we assessed whether gabapentin (0, 10, 30, 120 mg/kg, IG) pretreatment alters sensitivity to experimenter- and self-administered alcohol, and whether gabapentin alone has alcohol-like discriminative stimulus effects in rats trained to discriminate a moderate alcohol dose (1 g/kg, IG) vs. water. Second, we assessed whether gabapentin (0, 10, 30, 60 mg/kg, IG) would alter alcohol self-administration in rats with a history of moderate alcohol consumption. Gabapentin pretreatment potentiated the interoceptive effects of both experimenter-administered and self-administered alcohol in discrimination-trained rats. Additionally, the highest gabapentin doses tested (30 and 120 mg/kg) were found to have partial alcohol-like discriminative stimulus effects when administered alone (e.g., without alcohol). In the self-administration trained rats, gabapentin pretreatment (60 mg/kg) resulted in an escalation in alcohol self-administration. Given the importance of interoceptive drug cues in priming and maintaining self-administration, these data define a specific behavioral mechanism (i.e., potentiation of alcohol effects) by which gabapentin may increase alcohol self-administration in non-dependent populations.

In young (4-week-old) male and female spontaneously hypertensive (SH) rats, ethanol metabolic rate in vivo and hepatic alcohol dehydrogenase activity in vitro are high and not different in the two sexes. In males, ethanol metabolic rate falls markedly between 4 and 10 weeks of age, which coincides with the time of development of sexual maturity in the rat. Alcohol dehydrogenase activity is also markedly diminished in the male SH rat and correlates well with the changes in ethanol metabolism. There is virtually no influence of age on ethanol metabolic rate and alcohol dehydrogenase activity in the female SH rat. Castration of male SH rats prevents the marked decrease in ethanol metabolic rate and alcohol dehydrogenase activity, whereas ovariectomy has no effect on these parameters in female SH rats. Chronic administration of testosterone to castrated male SH rats and to female SH rats decreases ethanol metabolic rate and alcohol dehydrogenase activity to values similar to those found in mature males. Chronic administration of oestradiol-17β to male SH rats results in marked stimulation of ethanol metabolic rate and alcohol dehydrogenase activity to values similar to those found in female SH rats. Chronic administration of ethanol to male SH rats from 4 to 11 weeks of age prevents the marked age-dependent decreases in ethanol metabolic rate and alcohol dehydrogenase activity, but has virtually no effect in castrated rats. In the intoxicated chronically ethanol-fed male SH rats, serum testosterone concentrations are significantly depressed. In vitro, testosterone has no effect on hepatic alcohol dehydrogenase activity of young male and female SH rats. In conclusion, in the male SH rat, ethanol metabolic rate appears to be limited by alcohol dehydrogenase activity and is modulated by testosterone. Testosterone has an inhibitory effect and oestradiol has a testosterone-dependent stimulatory effect on alcohol dehydrogenase activity and ethanol metabolic rate in these animals. PMID:6990919

Many persons who drink excessively remain unidentified and do not receive interventions. Screening and intervention using the World Wide Web could make such services more accessible and therefore more widely used. To evaluate the use of a novel alcohol screening and brief intervention Web site. A Web site was developed, posted, and its use was evaluated. We analyzed a sample of visitors who completed alcohol screening over a 14-month period to describe their alcohol use, and their use of portions of the Web site that provide information and referral resources. The Internet. Web site visitors, with a focus on visitors who completed an alcohol-screening questionnaire about their own drinking. Brief intervention via the Web site, consisting mainly of feedback, advice, and a menu of change options and referral information. Self-reported drinking amounts and alcohol screening test scores, and utilization of Web site components. Visitors completed online alcohol screening questionnaires at a rate of 50,711/year of 115,925 visitors/year. In a 14-month period, 39,842 adults completed the questionnaire about their own drinking habits; 66% were men, 90% reported drinking hazardous amounts (per occasion or typical weekly amounts), 88% reported binge (per occasion) drinking, and 55% reported typically exceeding weekly risky drinking limits. Most (65%) had alcohol screening test results (AUDIT > or = 8) consistent with alcohol abuse or dependence; similar proportions of women and men were hazardous drinkers. One-fifth of visitors visited portions of the Web site that provided additional information about alcohol use and referrals. Visitors with possible alcohol abuse or dependence were more likely than those without these disorders to visit a part of the Web site designed for those seeking additional help (33% vs. 8%, P < 0.0001). A well-publicized, easily accessible, research-based screening and intervention Web site can attract many users, most of whom are drinking excessively, and many of whom avail themselves of referral information after receiving individualized feedback.

Stress is known to play an important role in alcohol abuse while binge drinking may increase individuals’ susceptibility to development of alcohol dependence. We set out to investigate whether binge drinkers (BD) compared to non-binge drinkers (NBD) are at a greater risk of increasing their desire for alcohol following experimental stress-induction (modified Trier Social Stress Test) (Experiment 1) and to explore the biological mechanisms underlying such an effect (Experiment 2). Pre-clinical evidence suggests that serotonin may mediate stress-induced reinstatement of alcohol intake. We therefore tested whether dietary tryptophan enhancement would modulate stress-induced desire for alcohol and whether it would affect the two populations (BD/NBD) differently. In Experiment 1 (14 NBD, 10 BD subjects; mean weekly alcohol intake 50.64 units) stress-induction selectively increased Strong Desire for alcohol (SD) compared to the non-stressful condition in BDs. Throughout the experiment, BDs reported greater Negative Reinforcement type of craving than NBDs but also a higher expectancy of alcohol-induced negative effects. In Experiment 2, forty-one subjects (22 NBD, 19 BD; mean alcohol intake 38.81 units) were given either the tryptophan-rich (TRP+; 9BD, 11NBD) or the control (CTR; 10BD, 11NBD) diet before undergoing stress-induction. In BDs, TRP+ diet prevented the stress-induced increase in SD that was observed in individuals receiving the CTR diet. In NBDs, TRP+ diet appeared to facilitate an increase in SD. These findings suggest that BDs may indeed be at a greater risk than NBDs of increasing their craving for alcohol when stressed. Furthermore, while enhancement of 5-HT function may moderate the impact of stress on craving in BDs, it seems to facilitate stress-induced craving in NBDs, suggesting that the serotonergic system may be differentially involved depending on individuals’ binge drinking status.

Men from a clinical treatment setting suffering from alcohol dependence, and randomly selected men from the community diagnosed as having alcohol abuse and/or dependence, completed the Parental Bonding Instrument. The men from the alcohol treatment setting perceived both parents as having been uncaring and overprotective. In the general population sample, an uncaring and overprotective parental style was strongly associated with childhood conduct disorder, but not with alcohol disorder symptoms. This discrepancy in perceived parenting highlights the difficulties in extrapolating findings about aetiological factors for alcohol disorders from clinical samples. It also suggests that childhood conduct disorder and adult antisocial behaviour could influence which men with alcohol disorders receive inpatient treatment.

To help clinicians to identify the severity of alcohol use disorders (AUDs) from optimal thresholds found for recommended scales. Especially, taking account of the high prevalence of alcohol dependence among patients admitted to the emergency department (ED) for acute alcohol intoxication (AAI), we propose to define thresholds of severity of dependence based on the AUDIT score. All patients admitted to the ED with AAI (blood alcohol level >0.8 g/L), in a 2-month period, were assessed using the CAGE, RAPS-QF, and AUDIT, with the alcohol dependence/abuse section of the mini international neuropsychiatric interview (MINI) used as the gold standard. To explore the relation between the AUDIT and the MINI the sum of the positive items on the MINI (dependence) as a quantitative variable and as an ordinal parameter were analyzed. From the threshold score found for each scale we proposed intervals of severity of AUDs. The mean age of the sample (122 males, 42 females) was 46 years. Approximately 12% of the patients were identified with alcohol abuse and 78% with dependence (DSM-IV). Cut points were determined for the AUDIT in order to distinguish mild and moderate dependence from severe dependence. A strategy of intervention based on levels of severity of AUD was proposed. Different thresholds proposed for the CAGE, RAPS4-QF, and AUDIT could be used to guide the choice of intervention for a patient: brief intervention, brief negotiation interviewing, or longer more intensive motivational intervention.

Alcohol dependence is a progressive chronic disorder characterized by narrowing of the drinking repertoire, salience of drinking, tolerance and withdrawal phenomenon, compulsion to drink, and frequent relapses. Baclofen has been shown to promote abstinence, to reduce craving, and to reduce anxiety in alcohol-dependent individuals, and it promises to be a useful agent, although clinical data are limited at present. The current study aimed to test the utility of baclofen, a GABA agonist, in improving the relapse rates in alcohol-dependent subjects. A total of 122 alcohol-dependent subjects were randomized into two groups. Groups were administered baclofen (30 mg/day) or benfothiamine (a nutritional supplement) using an open label design. Both groups received brief motivational intervention. Subjects were assessed at 0, 2, 4, 8, and 12 weeks for the primary outcome measures: time to first relapse, heavy drinking days, cumulative abstinence duration, and craving (measured by the Obsessive Compulsive Drinking Scale (OCDS)). Seventy-two participants received baclofen, and 50 received benfothiamine. Participants receiving baclofen remained abstinent for significantly more days than the benfothiamine group (p < 0.05). The percentage of heavy drinking days was significantly lower in the baclofen group (p = 0.001). Craving and anxiety scores (Hamilton Anxiety Rating Scale) were also significantly decreased in the baclofen group relative to the control group (p = 0.001). Time to first relapse was similar in both groups. In this open-label trial, alcohol-dependent participants receiving baclofen showed significant improvements in drinking outcomes compared with participants receiving benfothiamine. This study provides further evidence that baclofen is useful for the treatment of alcohol dependence.

Although access to and consideration of pharmacological treatments for alcohol dependence are consensus standards of care, receipt of these medications by patients is generally rare and highly variable across treatment settings. The goal of the present project was to survey and interview the clinicians, managers, and pharmacists affiliated with addiction treatment programs within Veterans Health Administration (VHA) facilities to learn about their perceptions of barriers and facilitators regarding greater and more reliable consideration of pharmacological treatments for alcohol dependence. Fifty-nine participants from 19 high-adopting and 11 low-adopting facilities completed the survey (facility-level response rate = 50%) and 23 participated in a structured interview. The top 4 barriers to increased consideration and use of pharmacotherapy for alcohol dependence were consistent across high- and low-adopting facilities and included perceived low patient demand, pharmacy procedures or formulary restrictions, lack of provider skills or knowledge regarding pharmacotherapy for alcohol dependence, and lack of confidence in treatment effectiveness. Low patient demand was rated as the most important barrier for oral naltrexone and disulfiram, whereas pharmacy or formulary restrictions were rated as the most important barrier for acamprosate and extended-release naltrexone. The 4 strategies rated across low- and high-adopting facilities as most likely to facilitate consideration and use of pharmacotherapy for alcohol dependence were more education to patients about existing medications, more education to health care providers about medications, increased involvement of physicians in treatment for alcohol dependence, and more compelling research on existing medications. This knowledge provides a foundation for designing, deploying, and evaluating targeted implementation efforts.

Background Alcohol dependence is a significant and costly problem in the UK yet only 6% of people a year receive treatment. Current service provision based on the treatment of acute episodes of illness and emphasising personal choice and motivation results in a small proportion of these patients engaging with alcohol treatment. There is a need for interventions targeted at the population of alcohol dependent patients who are hard to engage in conventional treatment. Assertive Community Treatment (ACT), a model of care based on assertive outreach, has been used for treating patients with severe mental illnesses and presents a promising avenue for engaging patients with primary alcohol dependence. So far there has been little research on this. Methods/Design In this single blind exploratory randomised controlled trial, a total of 90 alcohol dependent participants will be recruited from community addiction services. After completing a baseline assessment, they will be assigned to one of two conditions: (1) ACT plus care as usual, or (2) care as usual. Those allocated to the ACT plus care as usual will receive the same treatment that is routinely provided by services, plus a trained key worker who will provide ACT. ACT comprises intensive and assertive contact at least once a week, over 50% of contacts in the participant's home or local community, and comprehensive case management across social and health care, for a period of one year. All participants will be followed up at 6 months and 12 months to assess outcome post randomisation. The primary outcome measures will be alcohol consumption: mean drinks per drinking day and percentage of days abstinent measured by the Time Line Follow Back interview. Secondary outcome measures will include severity of alcohol dependence, alcohol related problems, motivation to change, social network involvement, quality of life, therapeutic relationship and service use. Other outcome variables are treatment engagement including completion of assessment, detoxification and aftercare. Discussion Results of this trial will help clarify the potential beneficial effects of ACT for people with alcohol dependence and provide information to design a definitive trial.

Alcohol consumption with its addictive potential may lead to physical and psychological dependence as well as systemic toxicity all of which have serious detrimental health outcomes in terms of morbimortality. Despite the harmful potential of alcohol use disorders, the disease is often not properly managed, especially in ambulatory care. Psychiatric and general practitioners in ambulatory care are first in line to detect and manage patients with excessive alcohol consumption. However, this is still often regarded as an acute medical condition and its management is generally considered only over the short-term. On the contrary, alcohol dependence has been defined as a primary chronic disease of the brain reward, motivation, memory and related circuitry, involving the signalling pathway of neurotransmitters such as dopamine, opioid peptides, and gamma-aminobutyric acid. Thus, it should be regarded in terms of long-term management as are other chronic diseases. To propose a standard pathway for the management of alcohol dependence in ambulatory care in terms of duration of treatment and follow-up. Given the lack of official recommendations from health authorities which may help ambulatory care physicians in long-term management of patients with alcohol dependence, we performed a review and analysis of the most recent literature regarding the long-term management of other chronic diseases (diabetes, bipolar disorders, and depression) drawing a parallel with alcohol dependence. Alcohol dependence shares many characteristics with other chronic diseases, including a prolonged duration, intermittent acute and chronic exacerbations, and need for prolonged and often-lifelong care. In all cases, this requires sustained psychosocial changes from the patient. Patient motivation is also a major issue and should always be taken into consideration by psychiatric and general practitioners in ambulatory care. In chronic diseases, such as diabetes, bipolar disorders, or depression, psychosocial and motivational interventions have been effective to improve the patient's emotional functioning and to prevent or delay relapses. Such interventions help patients to accept their disease and to promote long-term therapeutic plans based on treatment adherence, behavioural changes, self-management and self-efficacy. The management of alcohol-dependence in ambulatory care should be addressed similarly. Therapeutic monitoring may be initiated to manage alcohol use disorders, including alcohol dependence, especially when the patient is unwilling or unready for alcohol withdrawal (i.e. using the strategy of reduction of alcohol consumption, which is considered a possible intermediate step toward abstinence). Alcohol dependence needs long-term medical supervision, and the therapeutic success depends on the initiation of sustained monitoring at the time of diagnosis (initiating phase with several consultations over 2-4 weeks) with psychosocial and motivational interventions in order to address all the patient uncertainties, to involve him/her in a proactive disease management plan, and to insure adherence to treatment, behavioural changes and new lifestyle. A close monitoring (once a month during the first 6 months) during a consolidation phase is necessary. Finally, a regular monitoring should be maintained overtime after 6-12 months in order to insure that the patient maintains a minimal consumption during the first year, to consolidate the patient's motivation, to abstain in at risk situations, and to maintain a controlled consumption or abstinence.

This study investigated the association of academic outcomes, romantic relationships, and substance use (tobacco, marijuana, cocaine) with alcohol dependence in a sample of Latino (N = 1,143) college students. Secondary data analysis was conducted on measures of grade point average in college, relationship satisfaction, drug use, and alcohol dependence. Latino college students who reported alcohol dependency had significant relational dissatisfaction and poor academic outcomes. Thus, lower grade point average and relationship dissatisfaction were associated with alcohol dependence. By focusing specifically on a Mexican American population, this study adds important information to current research regarding the commonality and differences across cultural groups regarding drug use and dependence and further clarifies the risk factors associated with substance use and dependency in a population that is vulnerable for at-risk behaviors. This study also offers insight into potential targets of treatment and intervention for this cultural group.

The present study examined the effects of protracted alcohol withdrawal on affectivity, craving, selective attention and executive functions (EFs) in alcohol-dependent patients. Selective attention (The D2 Cancellation Test), flexibility (Trail Making Test), inhibition (Stroop Task), decision making (Iowa Gambling Task), craving (Obsessive-Compulsive Drinking Scale) and state affectivity (Positive and Negative Affectivity Schedule) were assessed in alcohol-dependent patients (DSM-IV, n = 35) matched to non-alcohol-dependent participants (n = 22) at the onset (T1: day 1 or 2) and at the end (T2: days 14-18) of protracted withdrawal during rehab. Alcohol-dependent patients' abilities to focus their attention on relevant information, to switch from one pattern to another, to inhibit irrelevant information and to make advantageous choices were lower than those of control participants during both times of a withdrawal cure. No effect of time emerged from analyses for selective attention and EF deficits. Conversely, significant differences between T1 and T2 were observed for craving and affect scores indicating a weakening of alcohol craving and negative affect as well as an improvement of positive affect among patients from onset to the end of cure. Control functions of the Supervisory Attentional System (Norman and Shallice, 1986) were impaired and did not improve during a 3-week withdrawal cure, whereas alcohol craving and negative state affectivity significantly improved in parallel during this period. Implications for understanding the clinical processes of withdrawal are discussed.

Suicidal behavior has been recognized as an increasing problem among alcohol-dependent subjects. The aim of the study was to identify correlates of impulsive and non-impulsive suicide attempts among a treated population of alcohol-dependent patients. A total of 154 patients with alcohol dependence consecutively admitted for addiction treatment participated in the study. Suicidal behavior was assessed together with severity of alcohol dependence, childhood abuse, impulsivity, and family history. A stop-signal procedure was used as a behavioral measure of impulsivity. Lifetime suicide attempts were reported by 43% of patients in alcohol treatment; of which 62% were impulsive. Compared to patients without a suicide attempt, those with a non-impulsive attempt were more likely to have a history of sexual abuse (OR=7.17), a family history of suicide (OR=4.09), and higher scores on a personality measure of impulsiveness (OR=2.27). The only significant factor that distinguished patients with impulsive suicide attempts from patients without a suicide attempt and from patients with a non-impulsive suicide attempt was a higher level of behavioral impulsivity (OR=1.84-2.42). Retrospective self-report of suicide attempts and family history. Lack of diagnostic measure.

Case reports indicate that deep-brain stimulation in the nucleus accumbens may be beneficial to alcohol-dependent patients. The lack of clinical trials and our limited knowledge of deep-brain stimulation call for translational experiments to validate these reports. To mimic the human situation, we used a chronic-continuous brain-stimulation paradigm targeting the nucleus accumbens and other brain sites in alcohol-dependent rats. To determine the network effects of deep-brain stimulation in alcohol-dependent rats, we combined electrical stimulation of the nucleus accumbens with functional magnetic resonance imaging (fMRI), and studied neurotransmitter levels in nucleus accumbens-stimulated versus sham-stimulated rats. Surprisingly, we report here that electrical stimulation of the nucleus accumbens led to augmented relapse behavior in alcohol-dependent rats. Our associated fMRI data revealed some activated areas, including the medial prefrontal cortex and caudate putamen. However, when we applied stimulation to these areas, relapse behavior was not affected, confirming that the nucleus accumbens is critical for generating this paradoxical effect. Neurochemical analysis of the major activated brain sites of the network revealed that the effect of stimulation may depend on accumbal dopamine levels. This was supported by the finding that brain-stimulation-treated rats exhibited augmented alcohol-induced dopamine release compared with sham-stimulated animals. Our data suggest that deep-brain stimulation in the nucleus accumbens enhances alcohol-liking probably via augmented dopamine release and can thereby promote relapse. PMID:27327255

Prior research has repeatedly shown that alcohol dependence is associated with a large range of impairments in psychological processes, which could lead to interpersonal deficits. Specifically, it has been suggested that these interpersonal difficulties are underpinned by reduced recognition and sharing of others' emotional states. However, this pattern of deficits remains to be clarified. This study thus aimed to investigate whether alcohol dependence is associated with impaired abilities in decoding contextual complex emotions and with altered sharing of others' emotions. Forty-one alcohol-dependent individuals (ADI) and 37 matched healthy individuals completed the Multifaceted Empathy Test, in which they were instructed to identify complex emotional states expressed by individuals in contextual scenes and to state to what extent they shared them. Compared to healthy individuals, ADI were impaired in identifying negative (Cohen's d = 0.75) and positive (Cohen's d = 0.46) emotional states but, conversely, presented preserved abilities in sharing others' emotional states. This study shows that alcohol dependence is characterized by an impaired ability to decode complex emotional states (both positive and negative), despite the presence of complementary contextual cues, but by preserved emotion-sharing. Therefore, these results extend earlier data describing an impaired ability to decode noncontextualized emotions toward contextualized and ecologically valid emotional states. They also indicate that some essential emotional competences such as emotion-sharing are preserved in alcohol dependence, thereby offering potential therapeutic levers.
