    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.

    Therapeutic success in the treatment of alcohol use disorders highly depends on an appropriate diagnosis. The Substance Dependence Severity Scale –SDSS- is a scale that assesses substance dependence in dimensional terms and that follows the diagnostic criteria established by the international classification systems. The aim of this study is to provide validity evidence for the severity dimension of the alcohol dependence scale of the SDSS comparing it with the Mini International Neuropsychiatric Interview –MINI-, and others variables related to substance use included in the EuropASI. A total of 109 patients admitted for treatment in the Drug Abuse Center Services of Huelva who had used alcohol in the month previous to the interview participated. The SDSS, MINI and EuropASI were administered. The diagnostic capacity of the SDSS was assessed by Receiver Operating Characteristic (ROC) curve analysis, taking the MINI dependence diagnosis as standard. The area under the ROC curve (AUC) was 0.917 (CI=0.867-0.968). The trade-off between parameters was detected for a score of 9, with suitable values of sensitivity and specificity (83.58% and 83.72%). The results support the use of the SDSS for the diagnosis of alcohol dependence and for assessment the severity of dependence. Administration of this scale makes it possible to obtain information, with a single score, on how severe the disorder is and whether the dependence criteria have been met.

    Baclofen is often prescribed in high doses to fight cravings experienced by alcohol-dependent patients. Such an increase in the availability of baclofen is concerning. This study aimed to determine the change in number and profile of self-poisoning with baclofen over time, as baclofen has become increasingly popular, in order to describe the severity of self-poisoning with baclofen and to focus on co-existing alcohol use disorders, and psychiatric illnesses determine predictors of severity. This was a retrospective study of self-poisoning with baclofen as reported by the western France Poison Control Center (PCC), which represents a population of more than 12 million people from January 2008 to March 2014. One hundred and eleven cases of self-poisoning with baclofen were reported to the western France PCC (62 males and 49 females; average age 39 ± 12). Poisoning severities were as follows: 'null' (nine cases), 'minor' (37 cases), 'moderate' (19 cases) and 'high' (46 cases, including four deaths). The most frequently reported symptoms were neurological (45%) and cardiovascular (27%). The severity was significantly associated with psychiatric disorders (OR = 2.9; p = 0.03). Baclofen, prescribed in high doses, may lead to severe poisoning, particularly in patients with psychiatric illnesses. Authorities should put forward a new policy for prescribing the drug as a treatment for alcohol dependence. © 2017 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    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.

    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.

    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

    Illness severity and self-efficacy are two constructs of growing interest as predictors of clinical response in alcoholism. Using alternative measures of illness severity (DSM-IV symptom count, Alcohol Dependence Scale, and Addiction Severity Index) and self-efficacy (brief version of the Situational Confidence Questionnaire) rigorously controlled for theoretically important background variables, we studied their unique contribution to multiple indices of relapse, relapse latency, and use of alternative coping behaviors in a large, heterogeneous clinical sample. The Alcohol Dependence Scale contributed to the prediction of 4 of 5 relapse indicators. The SCQ failed to predict relapse behavior or its precursor, coping response. The findings emphasize the predictive validity of severity of dependence as a course specifier and underline the need for more sensitive and externally valid measures of cognitive processes such as self-efficacy for application in future studies of posttreatment behavior.

    Brief alcohol screening questionnaires are increasingly used to identify alcohol misuse in routine care, but clinicians also need to assess the level of consumption and the severity of misuse so that appropriate intervention can be offered. Information provided by a patient's alcohol screening score might provide a practical tool for assessing the level of consumption and severity of misuse. This post hoc analysis of data from the 2001 to 2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) included 26,546 U.S. adults who reported drinking in the past year and answered additional questions about their consumption, including Alcohol Use Disorders Identification Test-Consumption questionnaire (AUDIT-C) alcohol screening. Linear or logistic regression models and postestimation methods were used to estimate mean daily drinking, the number of endorsed alcohol use disorder (AUD) criteria ("AUD severity"), and the probability of alcohol dependence associated with each individual AUDIT-C score (1 to 12), after testing for effect modification by gender and age. Among eligible past-year drinkers, mean daily drinking, AUD severity, and the probability of alcohol dependence increased exponentially across increasing AUDIT-C scores. Mean daily drinking ranged from < 0.1 to 18.0 drinks/d, AUD severity ranged from < 0.1 to 5.1 endorsed AUD criteria, and probability of alcohol dependence ranged from < 1 to 65% across scores 1 to 12. AUD severity increased more steeply across AUDIT-C scores among women than men. Both AUD severity and mean daily drinking increased more steeply across AUDIT-C scores among younger versus older age groups. Results of this study could be used to estimate patient-specific consumption and severity based on age, gender, and alcohol screening score. This information could be integrated into electronic decision support systems to help providers estimate and provide feedback about patient-specific risks and identify those patients most

    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

    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

    Preclinical data implicate the reinforcing effects of alcohol to be mediated by interaction between the opioid and dopamine systems of the brain. Specifically, alcohol-induced release of β-endorphins stimulates μ-opioid receptors (MORs), which is believed to cause dopamine release in the brain reward system. Individual differences in opioid or dopamine neurotransmission have been suggested to be responsible for enhanced liability to abuse alcohol. In the present study, a single dose of the MOR agonist remifentanil was administered in detoxified alcohol-dependent patients and healthy control subjects to mimic the β-endorphin-releasing properties of ethanol and to assess the effects of direct MOR stimulation on dopamine release in the mesolimbic reward system. Availability of D(2/3) receptors was assessed before and after single-dose administration of the MOR agonist remifentanil in 11 detoxified alcohol-dependent patients and 11 healthy control subjects with positron emission tomography with the radiotracer [(18)F]fallypride. Severity of dependence as assessed with the Alcohol Use Disorders Identification Test was compared with remifentanil-induced percentage change in [(18)F]fallypride binding (Δ%BP(ND)). The [(18)F]fallypride binding potentials (BP(ND)s) were significantly reduced in the ventral striatum, dorsal putamen, and amygdala after remifentanil application in both patients and control subjects. In the patient group, ventral striatum Δ%BP(ND) was correlated with the Alcohol Use Disorders Identification Test score. The data provide evidence for a MOR-mediated interaction between the opioid and the dopamine system, supporting the assumption that one way by which alcohol unfolds its rewarding effects is via a MOR-(γ-aminobutyric acid)-dopamine pathway. No difference in dopamine release was found between patients and control subjects, but evidence for a patient-specific association between sensitivity to MOR stimulation and severity of alcohol dependence

    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.

    There is inconsistent evidence that alcohol-specific coping is a mechanism of change in cognitive-behavioral therapy (CBT) for alcohol use disorder (AUD). Our primary aim was to test whether baseline dependence severity moderates the mediational effect of CBT on drinking outcomes via coping. Secondary data analysis of Project MATCH , a multi-site alcohol treatment trial in which participants, recruited in out-patient and aftercare arms, were randomized to three treatments: CBT, motivational enhancement therapy (MET) and Twelve-Step facilitation (TSF). Nine research sites in the United States. A total of 1063 adults with AUD. The primary outcomes were percentage days abstinent and percentage heavy drinking days at the 1-year follow-up. Coping was assessed with the Processes of Change Questionnaire . Dependence severity was measured with the Alcohol Dependence Scale . Among the full available sample (across treatment arms), there were no significant moderated mediation effects. Double moderated mediation analyses indicated that several moderated mediation effects were moderated by treatment arm (all P < 0.05). In the out-patient arm, there were several significant moderated mediation effects (all P < 0.05), but no significant moderated mediation effects in the aftercare arm. For out-patient clients with high baseline dependence severity, end-of-treatment coping mediated the positive treatment effects of CBT, compared with both MET and TSF, on 1-year drinking outcomes (all P < 0.05). Coping did not mediate treatment effects of CBT among those with low or moderate dependence severity. In the Project MATCH out-patient sample, whether or not coping mediated the effects of cognitive-behavioral therapy for alcohol use disorder was conditional on dependence severity. End-of-treatment coping mediated the positive treatment effects of cognitive-behavioral therapy on 1-year drinking outcomes among out-patient clients when dependence severity was high, but not when

    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.

    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.

    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 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.

  1. Is dependence on one drug associated with dependence on other drugs? The cases of alcohol, caffeine and nicotine.

    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.

    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.

    The literature on symptoms of obsessive-compulsive disorder (OCD) in alcoholic patients is scarce and such symptoms can go unnoticed, worsening the prognosis of alcoholism. The objectives were to estimate the prevalence and severity of obsessive-compulsive symptoms in alcoholics undergoing outpatient treatment and to assess sociodemographic and clinical correlates, including suicidal behaviors. The instruments used in this cross-sectional study were the Obsessive-Compulsive Inventory - Revised (OCI-R), the Short Alcohol Dependence Data and the Beck Depression Inventory. After descriptive analyses, bivariate analyses between the categorical ("probable OCD": OCI-R≥27) and dimensional (OCI-R total and subscales scores) outcomes and all explanatory variables were conducted. Eleven (20.4%) of the 54 alcoholic patients (37 men and 17 women) presented "probable OCD", which was associated with lower income, more severe dependence, depression, lifetime suicidal thoughts and plans and suicide attempts. OCI-R severity (mean 16.0) was associated with the same predictors and with psychiatric hospitalization. Suicidal behaviors were mainly associated with the Obsession, Hoarding and Washing subscales. It is essential to investigate and treat OCD symptoms in alcoholics, as they are associated with greater severity of dependence, depression and suicidal behaviors. Longitudinal studies are required to assess the impact of OCD treatment on the clinical course of alcoholism. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  4. Automatic Avoidance Tendencies for Alcohol Cues Predict Drinking After Detoxification Treatment in Alcohol Dependence

    PubMed Central

    2016-01-01

    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.

    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.

    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

    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.

    Modulation of alcohol craving induced by challenge stimuli may predict the efficacy of new pharmacotherapies for alcoholism. We evaluated two pharmacological challenges, the α2-adrenergic antagonist yohimbine, which reinstates alcohol seeking in rats, and the serotonergic compound meta-chlorophenylpiperazine (mCPP), previously reported to increase alcohol craving in alcoholics. To assess the predictive validity of this approach, the approved alcoholism medication acamprosate was evaluated for its ability to modulate challenge-induced cravings. A total of 35 treatment seeking alcohol dependent inpatients in early abstinence were randomized to placebo or acamprosate (2997 mg daily). Following two weeks of medication, subjects underwent three challenge sessions with yohimbine, mCPP or saline infusion under double blind conditions, carried out in counterbalanced order, and separated by at least 5 days. Ratings of cravings and anxiety, as well as biochemical measures were obtained. In all, 25 subjects completed all three sessions and were included in the analysis. Cravings were modestly, but significantly higher following both yohimbine and mCPP challenge compared with saline infusion. The mCPP, but not yohimbine significantly increased anxiety ratings. Both challenges produced robust ACTH, cortisol and prolactin responses. There was a significant correlation between craving and the degree of alcoholism severity. Acamprosate administration did not influence craving. Both yohimbine and mCPP challenges lead to elevated alcohol craving in a clinical population of alcoholics, and these cravings correlate with alcoholism severity. Under the experimental conditions used, alcohol cravings induced by these two stimuli are not sensitive to acamprosate at clinically used doses. PMID:21289601

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.

    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.

    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.

    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

    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.

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.

    The Addiction Severity Index (ASI) was evaluated for its psychometric qualities in a Dutch alcoholic population admitted to an addiction treatment center in The Netherlands. Its factorial structure in this population was found to be consistent with the established six factor structure of the ASI. Reliability analysis revealed that the homogeneity of the subscales was acceptable with the exception of the Alcohol Scale. The six subscales were not highly intercorrelated. The results of this study indicate that the ASI is a useful instrument for the assessment of several problems associated with alcoholism. However, the Alcohol Scale appears to be limited as a diagnostic and research instrument in the field of inpatient treatment of alcohol dependence in The Netherlands.

    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

    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

    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.

    The aims of this study were to examine the level of dissociative symptoms in patients with different substance related disorders (alcohol dependence, drug dependence, and combined alcohol and drug dependence), and to investigate the influence of potentially traumatic events in childhood, age, gender, and posttraumatic stress disorder on the relationship between dissociative symptoms and type of substance abuse. Of the 459 participants (59.7% male) 182 (39.7%) were alcohol-dependent (A), 154 (33.6%) were drug-dependent (D), and 123 (26.8%) were dependent on both, alcohol and drugs (AD) based on the DSM-IV criteria for a current diagnosis. Participants completed the Childhood Trauma Questionnaire (CTQ) and the Dissociative Experiences Scale (DES). The International Diagnostics Checklist (IDCL) was administered to diagnose PTSD. Higher levels of dissociation were observed in patients with drug dependence as compared to patients with mere alcohol dependence (mean DES group A: 9.9+/-8.8; group D: 12.9+/-11.7; group AD: 15.1+/-11.3). However, when severity of potentially traumatic events in childhood, PTSD, age and gender were included in the analysis, the influence of the type of substance abuse did not prove to be statistically significant. The variable most strongly related to dissociative symptoms was severity of potentially traumatic events in childhood, in particular emotional abuse, even after controlling for PTSD and other potential confounders. It seems appropriate to screen SUD patients for dissociative symptoms, especially those with a more complex risk profile including (additional) drug abuse, female gender, younger age and most importantly a history of childhood trauma.

    The present study examined a range of injunctive norms for alcohol use and related consequences from less severe behaviors (e.g., drinking with friends) to more severe behaviors (e.g., drinking enough alcohol to pass out), and their relationship with alcohol consumption and alcohol-related negative consequences among college students. In addition, this research aimed to determine if these relationships between injunctive norms and consequences were moderated by alcohol consumption and level of identification with the typical same-sex college student. A random sample (N = 1,002) of undergraduates (56.9% female) completed a Web–based survey that was comprised of measures of drinking behavior, perceived approval of drinking behaviors that ranged in severity (i.e., injunctive norms), and level of identification with the typical same-sex college student. Results suggest that the association between negative consequences and injunctive drinking norms depend on one's own drinking behavior, identification with other students, and the severity of the alcohol use and related consequences for which injunctive norms are assessed. Findings are discussed in terms of false consensus and false uniqueness effects, and deviance regulation perspectives. Implications for preventative interventions are discussed. PMID:20565144

  4. Combined alcohol and energy drink use: hedonistic motives, adenosine, and alcohol dependence.

    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.

  5. Alcohol dependence as a chronic pain disorder

    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.

    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.

    Aims Alcohol dependence is associated with high rates of co-occurring disorders which impact health-related quality of life (HRQoL) and add to the cost-of-illness. This study investigated the burden of alcohol dependence and associated co-occurring conditions on health and productivity. Methods A cross-sectional survey was conducted in eight European countries. Physicians (Psychiatrists and General Practitioners) completed patient record forms, which included assessment of co-occurring conditions, and patients completed matching self-completion forms. Drinking risk level (DRL) was calculated and the relationship between DRL, co-occurring conditions, work productivity, hospitalisations and rehabilitation stays was explored. Results Data were collected for 2979 alcohol-dependent patients (mean age 48.8 ± 13.6 years; 70% male). In total, 77% of patients suffered from moderate-to-severe co-occurring psychiatric and/or somatic conditions. High DRL was significantly associated with depression, greater work productivity losses, increased hospitalisations and rehabilitation stays. Co-occurring conditions were significantly associated with poorer HRQoL and decreased work productivity, with a statistical trend towards an increased frequency of rehabilitation stays. Conclusions Alcohol-dependent patients manifest high rates of co-occurring psychiatric and somatic conditions, which are associated with impaired work productivity and HRQoL. The continued burden of illness observed in these already-diagnosed patients suggests an unmet need in both primary and secondary care. PMID:26246514

    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.

    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.

    The Allostatic Model proposes that Alcohol Use Disorder (AUD) is associated with a transition in the motivational structure of alcohol drinking: from positive reinforcement in early-stage drinking to negative reinforcement in late-stage dependence. However, direct empirical support for this preclinical model from human experiments is limited. This study tests predictions derived from the Allostatic Model in humans. Specifically, this study tested whether alcohol use severity (1) independently predicts subjective responses to alcohol (SR; comprised of stimulation/hedonia, negative affect, sedation and craving domains), and alcohol self-administration and 2) moderates associations between domains of SR and alcohol self-administration. Heavy drinking participants ranging in severity of alcohol use and problems (N = 67) completed an intravenous alcohol administration paradigm combining an alcohol challenge (target BrAC = 60 mg%), with progressive ratio self-administration. Alcohol use severity was associated with greater baseline negative affect, sedation, and craving but did not predict changes in any SR domain during the alcohol challenge. Alcohol use severity also predicted greater self-administration. Craving during the alcohol challenge strongly predicted self-administration and sedation predicted lower self-administration. Neither stimulation, nor negative affect predicted self-administration. This study represents a novel approach to translating preclinical neuroscientific theories to the human laboratory. As expected, craving predicted self-administration and sedation was protective. Contrary to the predictions of the Allostatic Model, however, these results were inconsistent with a transition from positively to negatively reinforced alcohol consumption in severe AUD. Future studies that assess negative reinforcement in the context of an acute stressor are warranted.

  11. Avoidance of alcohol-related stimuli in alcohol-dependent inpatients.

    Previous research has shown an attentional bias toward drug-related stimuli in heavy social drinkers. Attentional orientation to drug-related cues may lead to increased craving and preoccupation with the drug and impaired ability to focus attention on nondrug-related activities, resulting in renewed drug taking or relapse from drug abstinence. The aim of this study was to investigate whether alcohol-dependent inpatients would differ in their selective attention toward alcohol-related stimuli in comparison with a group of social drinking controls. Thirty-five alcohol-dependent inpatients were compared with a group of 39 social drinking controls matched for age, sex, and verbal IQ. Attentional bias was assessed using alcohol-related pictures in a dot probe detection task. Questionnaires were used to examine outcome expectancies after alcohol consumption, anxiety, mood, and craving. The alcoholic inpatients showed a bias away from the alcohol-related stimuli, scored higher on alcohol outcome expectancies, and on anxiety measures (both state and trait). They also presented with more negative mood compared with the control group. Craving was higher in the alcoholic group for the factor "loss of control over drinking." Alcoholic inpatients undergoing treatment based on the 12-step treatment of Alcoholics Anonymous (Minnesota model), which includes counseling, and intensive group, individual, and family psychotherapy, show an avoidance for drug-related stimuli and a perception of loss of control over drinking. We suggest that their increased perception of loss of control over drinking produces the avoidance from the drug-related stimuli.

    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.

    Anxiety-related characteristics, including anxiety sensitivity and trait anxiety, are elevated in individuals with alcohol and nicotine dependence and associated with greater difficulties with quitting smoking. However, little is known about how anxiety-related characteristics are related to smoking cessation outcomes in alcohol-dependent smokers. The present study, part of a larger smoking cessation clinical trial, examined associations between anxiety sensitivity, trait anxiety, nicotine withdrawal symptoms, smoking urges, and smoking cessation outcomes in a sample of 83 alcohol-dependent smokers. Participants were enrolled in concurrent alcohol and tobacco treatment as part of a substance-abuse intensive outpatient program. Smoking cessation treatment was administered in a 3-week cognitive-behavioral format that included 8 weeks of open-label nicotine patch treatment. Information on nicotine withdrawal, smoking urges, and CO-confirmed smoking consumption rates was collected at baseline, quit date, end of behavioral treatment, and at a 1-month follow-up. Higher levels of anxiety sensitivity were associated with more smoking urges due to anticipation of negative affect relief at quit date. Higher levels of trait anxiety were associated with more smoking urges due to positive reinforcement and anticipation of relief of negative affect at quit date, as well as more severe nicotine withdrawal symptoms at the end of treatment. Levels of anxiety sensitivity and trait anxiety were not associated with Cox regression survival times to relapse. These results indicate that for alcohol-dependent smokers, levels of anxiety sensitivity and trait anxiety are important to consider in the assessment and treatment of nicotine dependence.

    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.

    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.

    Alcoholism is a highly stigmatized condition, with both alcohol-dependent individuals and family members of the afflicted experiencing stigmatization. This study examined the severity of a parent's alcoholism and family topic avoidance about alcohol as two factors that are associated with family members' perceptions of stigma. Three dimensions of stigma were considered: discrimination stigma, disclosure stigma, and positive aspect stigma. In addition, this study assessed associations between perceived stigmatization and individuals' experiences of depressive symptoms, self-esteem, and resilience. Adult children of alcoholics (N = 622) were surveyed about family conditions, perceived stigma, and their emotional and psychological well-being. Regression analyses revealed that the severity of a parent's alcoholism predicted all three types of stigma for females, but not for males. In addition, family topic avoidance about alcohol predicted all types of stigma for males and discrimination stigma and positive aspect stigma for females. With few exceptions, the three types of stigma predicted depressive symptoms, self-esteem, and resilience for both male and female adult children of alcoholics. The results are discussed in terms of their implications for promoting a family environment that mitigates stigma and encourages emotional and psychological well-being. In 2012, approximately 3.3 million deaths worldwide were due to the harmful use of alcohol (World Health Organization [WHO], 2014). Individuals who abuse alcohol are susceptible to a variety of negative health outcomes (Rehm et al., 2009) and display inappropriate social behaviors (Klingemann, 2001; Schomerus et al., 2011a). General societal perceptions tend to characterize alcohol-dependent individuals as irresponsible and lacking in self-control (Schomerus et al., 2011b). Research in the United Kingdom found that 54% of the population believes alcohol-dependent individuals are personally to blame for their own

    This cohort study examined how predictors of alcohol dependence treatment outcomes work together over time by comparing pretreatment and posttreatment predictors. A sample of 274 alcohol-dependent patients was recruited and assessed at baseline, 6 months after treatment initiation (end of the active intervention phase), and 18 months after treatment initiation (end of the 12-month research follow-up phase). At each assessment point, the participants completed a battery of standardized tests [European Addiction Severity Index (EuropASI), Obsessive Compulsive Drinking Scale (OCDS), Alcohol Timeline Followback (TLFB), Fagerström, and International Personality Disorder Examination (IPDE)] that measured symptom severity and consequences; biological markers of alcohol consumption were also tested at each assessment point. A sequential strategy with univariate and multivariate analyses was used to identify how pretreatment and posttreatment predictors influence outcomes up to 1 year after treatment. Pretreatment variables had less predictive power than posttreatment ones. OCDS scores and biological markers of alcohol consumption were the most significant variables for the prediction of posttreatment outcomes. Prior pharmacotherapy treatment and relapse prevention interventions were also associated with posttreatment outcomes. The findings highlight the positive impact of pharmacotherapy during the first 6 months after treatment initiation and of relapse prevention during the first year after treatment and how posttreatment predictors are more important than pretreatment predictors.

    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.

    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 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.

    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.

    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.

    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

    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.

    Severe alcoholism can be associated with significant nutritional and vitamin deficiency, especially vitamin B1 (thiamine) which is associated with neurological deficits impacting mood and cognition. Alcohol consumption was reduced among female but not male alcoholics after supplementation with the high potency thiamine analog benfotiamine (BF). We examined the relationship between lifetime alcoholism severity, psychiatric symptoms and response to BF among the alcohol dependent men from this cohort. Eighty-five adult men (mean age=48±8 years) meeting DSM-IV-TR criteria for a current alcohol use disorder who were abstinent <30days participated in a randomized, double-blind, placebo-controlled trial of 600mg BF vs placebo (PL) for 6 months. Psychometric testing included a derived Lifetime Alcoholism Severity Score (AS), Symptom Checklist 90R (SCL-90R), and the Barratt Impulsivity Scale (BIS) at baseline and at 6 months. Baseline SCL-90-R scale scores for men with high alcoholism severity (AS≥24; N=46 HAS) were significantly greater than for men with low alcoholism severity (AS<24; N=39 LAS), but BIS scores did not differ. MANOVA modeling at follow-up (N=50 completed subjects) identified a significant treatment effect (F=2.5, df=10, p<0.03) and treatment×alcoholism severity level interaction (F=2.5, dfnum=10, dfden=30, p<0.03) indicating reduced SCL-90-R scores among BF treated, HAS males. Above normal plasma thiamine levels at follow-up predicted reduced depression scores in a BF-treated subset (F=3.2, p<0.09, N=26). BF appears to reduce psychiatric distress and may facilitate recovery in severely affected males with a lifetime alcohol use disorder and should be considered for adjuvant therapy in alcohol rehabilitation. #NCT00680121 High Dose Vitamin B1 to Reduce Abusive Alcohol Use.

    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.

    The high occurrence of childhood trauma in individuals with alcohol dependence is well-recognized. Nevertheless, researchers have rarely studied which types of childhood trauma often co-occur and how these combinations of different types and severities of childhood trauma are related to the patients' current addiction-related problems. We aimed to identify childhood trauma profiles in patients with alcohol dependence and examined relations of these trauma profiles with the patients' current addiction-related problems. In 347 alcohol-dependent patients, 5 types of childhood trauma (sexual abuse, physical abuse, emotional abuse, emotional neglect, and physical neglect) were measured using the Childhood Trauma Questionnaire. Childhood trauma profiles were identified using cluster analysis. The patients' current severity of addiction-related problems was assessed using the European Addiction Severity Index. We identified 6 profiles that comprised different types and severities of childhood trauma. The patients' trauma profiles predicted the severity of addiction-related problems in the domains of psychiatric symptoms, family relationships, social relationships, and drug use. Childhood trauma profiles may provide more useful information about the patient's risk of current addiction-related problems than the common distinction between traumatized versus nontraumatized patients.

    The main aim of this study was to investigate, in alcohol-dependent (AD) patients, the use of the 5 emotion regulation strategies specified in Gross's (1998, Rev Gen Psychol, 2, 271) process model of emotion regulation with the use of a semi-structured interview allowing a detailed and high-quality assessment of emotion regulation strategies. A secondary aim was to examine the possible influence of protracted abstinence and detoxification on emotion dysregulation. Finally, the association between the level of craving and the types of regulation strategies was investigated. Forty-four treatment-seeking AD patients with varying time spent in rehabilitation, and 26 healthy controls were interviewed using a version of the Emotion Regulation Interview (Werner et al., 2011, J Psychopathol Behav Assess, 33, 346) adapted to alcohol dependence. Compared to controls, AD patients reported significantly greater use of response modulation and attentional deployment, but lesser use of cognitive change. Among patients, (1) rehabilitation duration was positively correlated with the use of cognitive change and (2) the use of response modulation was positively associated with the level of craving. These findings clarify the specific pattern of emotion dysregulation associated with alcohol dependence. They also suggest that (1) abstinence is associated with a shift toward more adaptive emotion regulation patterns and that (2) inefficient regulation strategies may lead to craving and the maintenance of alcohol use. If these findings are confirmed through longitudinal and mediation designs, they will have important clinical implications. Copyright © 2015 by the Research Society on Alcoholism.

    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.

    The present study was designed to examine the influence of suicidality on relapse in alcohol-dependent patients. Specifically, a lifetime suicide attempt at baseline was used to predict relapse in the year after treatment. Also, the unique contribution of impulsive suicide attempts was examined. A total of 154 patients with alcohol dependence, consecutively admitted to four addiction treatment facilities in Warsaw, Poland participated in the study. Of the 154 eligible patients, 118 (76.6%) completed a standardized follow-up assessment at 12 months. Previous suicide attempts were common in adults treated for alcohol dependence with 43% patients in the present sample reporting an attempt at some point during their lifetime. Additionally, more than 62% of those with a lifetime suicide attempt reported making an impulsive attempt. Lifetime suicide attempts were not associated with post-treatment relapse (chi-square=2.37, d.f.=1, p=0.124). However, impulsive suicide attempts strongly predicted relapse (OR=2.81, 95% CI=1.13-6.95, p=0.026) and time to relapse (OR=2.10, 95% CI=1.18-3.74, p=0.012) even after adjusting for other measures of baseline psychopathology, depression, impulsivity, hopelessness and alcohol use severity. This study is the first to document the relationship between pre-treatment impulsive suicide attempts and higher likelihood of post-treatment relapse in alcohol-dependent patents. Clinicians should routinely conduct an assessment for previous suicide attempts in patients with alcohol use disorders, and when impulsive suicidality is reported, they should recognize the increased risk for relapse and formulate their patients' treatment plans accordingly with the goals of reducing both alcoholic relapse and suicide rates.

    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.

    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.

    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 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.

    Context Identification of genes contributing to alcohol dependence will improve our understanding of the mechanisms underlying this disorder. Objective To identify susceptibility genes for alcohol dependence through a genome-wide association study (GWAS) and follow-up study in a population of German male inpatients with an early age at onset. Design The GWAS included 487 male inpatients with DSM-IV alcohol dependence with an age at onset below 28 years and 1,358 population based control individuals. The follow-up study included 1,024 male inpatients and 996 age-matched male controls. All subjects were of German descent. The GWAS tested 524,396 single nucleotide polymorphisms (SNPs). All SNPs with p<10-4 were subjected to the follow-up study. In addition, nominally significant SNPs from those genes that had also shown expression changes in rat brains after chronic alcohol consumption were selected for the follow-up step. Results The GWAS produced 121 SNPs with nominal p<10-4. These, together with 19 additional SNPs from homologs of rat genes showing differential expression, were genotyped in the follow-up sample. Fifteen SNPs showed significant association with the same allele as in the GWAS. In the combined analysis, two closely linked intergenic SNPs met genome-wide significance (rs7590720 p=9.72×10-9; rs1344694 p=1.69×10-8). They are located on chromosome 2q35, a region which has been implicated in linkage studies for alcohol phenotypes. Nine SNPs were located in genes, including CDH13 and ADH1C genes which have been reported to be associated with alcohol dependence. Conclusion This is the first GWAS and follow-up study to identify a genome-wide significant association in alcohol dependence. Further independent studies are required to confirm these findings.

    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

Random allocation to a year of treatment with naltrexone (50 mg/day) or acamprosate (1665-1998 mg/day) was made in 157 recently detoxified alcohol-dependent men with moderate dependence (evaluated using the Addictions Severity Index and Severity of Alcohol Dependence Scale). All were patients whom a member of the family would accompany regularly to appointments. Alcohol consumption, craving and adverse events were recorded weekly for the first 3 months, and then bi-weekly, by the treating psychiatrist who was not blinded. At 3-monthly intervals, investigators who were blinded to the treatment documented patients' alcohol consumption based on patients' accounts, information given by the psychiatrists when necessary, and reports from patients' families. Serum gamma-glutamyltransferase (GGT) was also measured. Efforts were made to sustain the blindness of the investigators. The same investigator did not assess the same patient twice. The integrity of the blindness was not checked. There was no difference between treatments in mean time to first drink (naltrexone 44 days, acamprosate 39 days) but the time to first relapse (five or more drinks in a day) was 63 days (naltrexone) versus 42 days (acamprosate) (P = 0.02). At the end of 1 year, 41% receiving naltrexone and 17% receiving acamprosate had not relapsed (P = 0.0009). The cumulative number of days of abstinence was significantly greater, and the number of drinks consumed at one time and severity of craving were significantly less, in the naltrexone group compared to the acamprosate group, as was the percentage of heavy drinking days (P = 0.038). More patients in the acamprosate than the naltrexone group were commenced on disulfiram during the study. Naltrexone patients

  2. Assertive Community Treatment for alcohol dependence (ACTAD): study protocol for a randomised controlled trial

    PubMed Central

    2012-01-01

    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

    anticonvulsants reduced drinks/drinking days (11 studies, 1126 participants, mean difference (MD) -1.49, 95% Cl -2.32 to -0.65) and heavy drinking (12 studies, 1129 participants, standardised mean difference (SMD) -0.35, 95% Cl -0.51 to -0.19). Moreover, withdrawal for medical reasons (12 studies, 1410 participants, RR 1.22, 95% Cl 0.58 to 2.56, moderate-quality evidence) showed no evidence of difference, but for specific adverse effects (nine studies, 1164 participants), two of 18 adverse event outcomes favoured placebo. The direction of results was confirmed by subgroup analyses for topiramate and partially for gabapentin and valproate.Anticonvulsants versus naltrexone: No evidence of difference was shown in dropout rates (five studies, 528 participants, RR 0.74, 95% CI 0.52 to 1.06), severe relapse rates (four studies, 427 participants, RR 0.69, 95% Cl 0.44 to 1.07) and continuous abstinence rates (five studies, 528 participants, RR 1.21, 95% Cl 0.99 to 1.49); anticonvulsants were associated with fewer heavy drinking days (three studies, 308 participants, MD -5.21, 95% Cl -8.58 to -1.83), more days to severe relapse (three studies, 244 participants, MD 11.88, 95% Cl 3.29 to 20.46) and lower withdrawal for medical reasons (three studies, 245 participants, RR 0.13, 95% Cl 0.03 to 0.58). At the current stage of research, randomised evidence supporting the clinical use of anticonvulsants to treat alcohol dependence is insufficient. Results are conditioned by heterogeneity and by the low number and quality of studies comparing anticonvulsants with other medications. The uncertainty associated with these results leaves to clinicians the need to balance possible benefits/risks of treatment with anticonvulsants versus other medications as supported by evidence of efficacy.

    Item response theory analyses were used to examine alcohol abuse and dependence symptoms and diagnoses in adolescents. Previous research suggests that the DSM-IV alcohol use disorder (AUD) symptoms in adolescents may be characterized by a single dimension. The present study extends prior research with a larger and more comprehensive sample and an examination of an alternative diagnostic algorithm for AUDs. Approximately 5,587 adolescents between the ages of 12 and 18 years from adjudicated, clinical, and community samples were administered structured clinical interviews. Analyses were conducted to examine the severity of alcohol abuse and dependence symptoms and the severity of alcohol use problems (AUDs) within the diagnostic categories created by the DSM-IV. Although the DSM-IV diagnostic categories differ in severity of AUDs, there is substantial overlap and inconsistency in AUD severity of persons across these categories. Item Response Theory-based AUD severity estimates suggest that many persons diagnosed with abuse have AUD severity greater than persons with dependence. Similarly, many persons who endorse some symptoms but do not qualify for a diagnosis (i.e., diagnostic orphans) have more severe AUDs than persons with an abuse diagnosis. Additionally, two dependence items, "tolerance" and "larger/longer," show differences in severity between samples. The distinction between DSM-IV abuse and dependence based on severity can be improved using an alternative diagnostic algorithm that considers all of the alcohol abuse and dependence symptoms conjointly.

  5. Stimulus augmenting and field dependence in children of alcoholic fathers.

    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.

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.

    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

    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.

    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.

  10. A pilot study of oxcarbazepine versus acamprosate in alcohol-dependent patients.

    This pilot study has been designed to collect preliminary data on the use of a new antiepileptic drug in the management of alcoholic patients. Oxcarbazepine (OXC) blocks voltage-sensitive sodium channels. Its metabolite reduces high-voltage-activated calcium currents in striatal and cortical neurons, thus reducing glutamatergic transmission at corticostriatal synapses. This reduction is of interest in the treatment of alcohol dependence, as acamprosate (ACP) modulates NMDA receptors, resulting in an inhibition of glutamatergic transmission. Furthermore, OXC has revealed a mood-stabilizing effect in bipolar affective disorders. We have compared OXC with ACP in relapse prevention in recently withdrawn alcohol-dependent patients. We investigated the efficacy and safety of OXC (vs ACP) by conducting a 24-week randomized, parallel-group, open-label, clinical trial on 30 acutely detoxified alcoholic patients. Survival analyses (Kaplan-Meier) were performed to look for evidence of a longer "survival" of patients receiving OXC. We assessed time to first severe relapse and additional secondary endpoints. After withdrawal, time to severe relapse and time to first consumption of any ethanol by OXC patients were not longer than for ACP patients. Abstinent patients in both study groups showed a significantly lower obsessive compulsive drinking scale-German version (OCDS-G) than relapsed patients. No undesired effects occurred when OXC patients consumed alcohol. Our findings indicate that it could be worthwhile to test relapse prevention using OXC in an adequate sample. While the current sample size clearly limits further conclusions from this pilot study, it is noteworthy that OXC is well tolerated, even when alcohol is on board. Thus, in medication-based relapse prevention, OXC could be a promising alternative for alcoholic patients unable to benefit from ACP or naltrexone or those who have affective liability. OXC certainly merits a larger placebo-controlled trial.

    Interactive voice response (IVR), a computer-based interviewing technique, can be used within a computer-assisted telephone interview (CATI) survey to increase privacy and the accuracy of reports of sensitive attitudes and behaviours. Previous research using the 2005 National Alcohol Survey indicated no overall significant differences between IVR and CATI responses to alcohol-related problems and alcohol dependence. To determine if this result holds for demographic subgroups that could respond differently to modes of data collection, this study compares the prevalence rates of lifetime and last-year alcohol-related problems by gender, ethnicity, age and income subgroups obtained by IVR versus continuous CATI interviewing. As part of the 2005 National Alcohol Survey, subsamples of English-speaking respondents were randomly assigned to an IVR group that received an embedded IVR module on alcohol-related problems (n = 450 lifetime drinkers) and a control group that were asked identical alcohol-related problem items using continuous CATI (n = 432 lifetime drinkers). Overall, there were few significant associations. Among lifetime drinkers, higher rates of legal problems were found for white and higher income respondents in the IVR group. For last-year drinkers, a higher percentage of indicators of alcohol dependence was found for Hispanic respondents and women respondents in the CATI group. Data on alcohol problems collected by CATI provide largely comparable results to those from an embedded IVR module. Thus, incorporation of IVR technology in a CATI interview does not appear strongly indicated even for several key subgroups.

    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

    A considerable economic burden has been repeatedly associated with alcohol dependence (AD) - mostly calculated using aggregate data and alcohol-attributable fractions (top-down approach). However, this approach is limited by a number of assumptions, which are hard to test. Thus, cost estimates should ideally be validated with studies using individual data to estimate the same costs (bottom-up approach). However, bottom-up studies on the economic burden associated with AD are lacking. Our study aimed to fill this gap using the bottom-up approach to examine costs for AD, and also stratified the results by the following subgroups: sex, age, diagnostic approach and severity of AD, as relevant variations could be expected by these factors. 1356 primary health care patients, representative for two German regions. AD was diagnosed by a standardized instrument and treating physicians. Individual costs were calculated by combining resource use and productivity data representing a period of six months prior to the time of interview, with unit costs derived from the literature or official statistics. The economic burden associated with AD was determined via excess costs by comparing utilization of various health care resources and impaired productivity between people with and without AD, controlling for relevant confounders. Additional analyses for several AD characteristics were performed. Mean costs among alcohol dependent patients were 50 % higher compared to the remaining patients, resulting in 1836 € excess costs per alcohol dependent patient in 6 months. More than half of these excess costs incurred through increased productivity loss among alcohol dependent patients. Treatment for alcohol problems represents only 6 % of these costs. The economic burden associated with AD incurred mainly among males and among 30 to 49 year old patients. Both diagnostic approaches were significantly related to the economic burden, while costs increased with alcohol use disorder

    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.

    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.

    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.

    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.

    2014-01-01

    Background 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. Methods 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. Results The effects of single housing were age specific and affected Met-enkephalin-Arg6Phe7 (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. Conclusions 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

    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.

    Alcohol is responsible for a proportion of emergency admissions to hospital, with acute alcohol intoxication and chronic alcohol dependency (CAD) implicated. This study aims to quantify the proportion of hospital admissions through our emergency department (ED) which were thought by the admitting doctor to be (largely or partially) a result of alcohol consumption. ED of a UK tertiary referral hospital. All ED admissions occurring over 14 weeks from 1 September to 8 December 2012. Data obtained for 5497 of 5746 admissions (95.67%). Proportion of emergency admissions related to alcohol as defined by the admitting ED clinician. Proportion of emergency admissions due to alcohol diagnosed with acute alcohol intoxication or CAD according to ICD-10 criteria. 1152 (21.0%, 95% CI 19.9% to 22.0%) of emergency admissions were thought to be due to alcohol. 74.6% of patients admitted due to alcohol had CAD, and significantly greater than the 26.4% with 'Severe' or 'Very Severe' acute alcohol intoxication (p<0.001). Admissions due to alcohol differed to admissions not due to alcohol being on average younger (45 vs 56 years, p<0.001) more often male (73.4% vs 45.1% males, p<0.001) and more likely to have a diagnosis synonymous with alcohol or related to recreational drug use, pancreatitis, deliberate self-harm, head injury, gastritis, suicidal ideation, upper gastrointestinal bleeds or seizures (p<0.001). An increase in admissions due to alcohol on Saturdays reflects a surge in admissions with acute alcohol intoxication above the weekly average (p=0.003). Alcohol was thought to be implicated in 21% of emergency admissions in this cohort. CAD is responsible for a significantly greater proportion of admissions due to alcohol than acute intoxication. Interventions designed to reduce alcohol-related admissions must incorporate measures to tackle CAD. Published by the BMJ Publishing Group Limited.

    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

    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

    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.

    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.

    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

  8. Increased startle potentiation to unpredictable stressors in alcohol dependence: Possible stress neuroadaptation in humans

    2017-01-01

    Stress plays a key role in addiction etiology and relapse. Rodent models posit that following repeated periods of alcohol and other drug intoxication, compensatory allostatic changes occur in the central nervous system (CNS) circuits involved in behavioral and emotional response to stressors. We examine a predicted manifestation of this neuroadaptation in recently abstinent alcohol dependent humans. Participants completed a translational laboratory task that uses startle potentiation to unpredictable (vs. predictable) stressors implicated in the putative CNS mechanisms that mediate this neuroadaptation. Alcohol dependent participants displayed significantly greater startle potentiation to unpredictable than predictable stressors relative to non-alcoholic controls. The size of this effect covaried with alcohol-related problems and degree of withdrawal syndrome. This supports the rodent model thesis of a sensitized stress response in abstinent alcoholics. However, this effect could also represent pre-morbid risk or mark more severe and/or comorbid psychopathology. Regardless, pharmacotherapy and psychological interventions may target unpredictable stressor response to reduce stress-induced relapse. PMID:28394145

    Most studies that have examined alcohol use immediately prior to intimate partner violence (IPV) have been limited to male-to-female partner violence (MFPV) and are subject to a number of methodological limitations. We add new information concerning the relationship between alcohol involvement and severity of IPV, MFPV, and female-to-male partner violence (FMPV). We analyzed data from a 1995 U.S. national population-based survey of couples > or = 18 years old. We examined 436 couples who reported IPV and had information on alcohol involvement with IPV. We measured IPV using a revised Conflict Tactics Scale, Form R that asked respondents about 11 violent behaviors in the past year. Respondents were classified into mutually exclusive categories as having experienced mild only or mild + severe ("severe") IPV, MFPV or FMPV. Respondents were also asked if they or their partner were drinking at the time the violent behavior occurred and were classified as exposed to IPV with or without alcohol involvement. We estimated proportions, odds ratios, 95% confidence intervals, and p-values of the proposed associations, accounting for the complex survey design. Overall, 30.2% of couples who reported IPV reported alcohol involved IPV; 69.8% reported no alcohol involvement. In adjusted analyses, those reporting severe (vs. mild only) IPV were more than twice as likely to report alcohol involvement. In adjusted analyses, those reporting severe (vs. mild) MFPV or FMPV were more likely to report female but not male alcohol involvement. Though estimates were positive and strong, most confidence intervals were compatible with a wide range of estimates including no association. Our findings suggest alcohol involvement of either or both in the couple increases the risk of severe IPV. Our findings also suggest female alcohol use may play an important role in determining the severity of IPV, MFPV or FMPV.

    Background Ascertaining agreement between DSM-IV and DSM-5 is important to determine the applicability of treatments for DSM-IV conditions to persons diagnosed according to the proposed DSM-5. Methods Data from a nationally representative sample of US adults were used to compare concordance of past-year DSM-IV Opioid, Cannabis, Cocaine and Alcohol Dependence with past-year DSM-5 disorders at thresholds of 3+, 4+ 5+ and 6+ positive DSM-5 criteria among past-year users of opioids (n=264), cannabis (n=1,622), cocaine (n=271) and alcohol (n=23,013). Substance-specific 2×2 tables yielded overall concordance (kappa), sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV). Results For DSM-IV Alcohol, Cocaine and Opioid Dependence, optimal concordance occurred when 4+ DSM-5 criteria were endorsed, corresponding to the threshold for moderate DSM-5 Alcohol, Cocaine and Opioid Use Disorders. Maximal concordance of DSM-IV Cannabis Dependence and DSM-5 Cannabis Use Disorder occurred when 6+ criteria were endorsed, corresponding to the threshold for severe DSM-5 Cannabis Use Disorder. At these optimal thresholds, sensitivity, specificity, PPV and NPV generally exceeded 85% (>75% for cannabis). Conclusions Overall, excellent correspondence of DSM-IV Dependence with DSM-5 Substance Use Disorders was documented in this general population sample of alcohol, cannabis, cocaine and opioid users. Applicability of treatments tested for DSM-IV Dependence is supported by these results for those with a DSM-5 Alcohol, Cocaine or Opioid Use Disorder of at least moderate severity or Severe Cannabis Use Disorder. Further research is needed to provide evidence for applicability of treatments for persons with milder substance use disorders. PMID:23642316

    Resilience and recovery are of increasing importance in the field of alcohol dependence (AD). This paper describes how imaging studies in man can be used to assess the neurobiological correlates of resilience and, if longitudinal, of disease trajectories, progression rates and markers for recovery to inform treatment and prevention options. Original articles on recovery and resilience in alcohol addiction and its neurobiological correlates were identified from 'PubMed' and have been analyzed and condensed within a systematic literature review. Findings deriving from (f)MRI and PET studies have identified links between increased resilience and less task-elicited neural activation within the basal ganglia, and benefits of heightened neural prefrontal cortex (PFC) engagement regarding resilience in a broader sense, namely resilience against relapse in early abstinence of AD. Furthermore, findings consistently propose at least partial recovery of brain glucose metabolism and executive and general cognitive functioning, as well as structural plasticity effects throughout the brain of alcohol-dependent patients during the course of short, medium and long-term abstinence, even when patients only lowered their alcohol consumption to a moderate level. Additionally, specific factors were found that appear to influence these observed brain recovery processes in AD, e.g. genotype-dependent neuronal (re)growth, gender-specific neural recovery effects, critical interfering effects of psychiatric comorbidities, additional smoking or marijuana influences, or adolescent alcohol abuse. Neuroimaging research has uncovered neurobiological markers that appear to be linked to resilience and improved recovery capacities that are furthermore influenced by various factors such as gender or genetics. Consequently, future system-oriented approaches may help to establish a broad neuroscience-based research framework for alcohol dependence. This article is protected by copyright. All rights

  12. Alcohol-induced changes in opioid peptide levels in adolescent rats are dependent on housing conditions.

    2014-12-01

    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

    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.

    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

    In accounting for the consistent finding that alcoholics are more field dependent than other groups, research generally supports the predisposition rather than the consequence hypothesis. In this study 32 alcoholics were tested for field dependence with Embedded Figures on admission to and at discharge from a 60-d treatment program. A large and significant drop in the field dependence measure was found, supporting the consequence hypothesis. The pre-posttime period not controlled in other studies, allowing for clearing acute effects and improved nutrition, health, and test motivation, amy account for this change.

    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.

    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.

    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.

    Chronic excessive alcohol consumption induces multiple brain damages. Secondary cognitive disorders include executive functions, episodic memory and visuospatial capacities. The severity of these alcohol induced disorders may vary between sub-clinical manifestations (that may, nevertheless, interfere with medical management) and more important ones like Korsakoff syndrome or dementia. The latter are usually irreversible but many of these manifestations are potentially reversible with persistent abstinence. It therefore appears of particular importance to clearly define neuropsychological management in order to identify and evaluate the type and severity of alcohol-related cognitive disorders. The patients may then be offered rehabilitation for these cognitive impairments. This is the first step of a complete addiction program based especially on cognitive behavioral therapies.

    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.

    This study examined the validity of classifying substance abusers based on temperament and dependence severity, and expanded the scope of typology differences to proximal determinants of use (e.g., expectancies, motives). Patients were interviewed about substance use, depression, and family history of alcohol and drug abuse. Self-report instruments measuring temperament, expectancies, and motives were completed. Participants were 147 male veterans admitted to inpatient substance abuse treatment at a U.S. Department of Veterans Affairs medical center. Cluster analysis identified four types of users with two high substance problem severity and two low substance problem severity groups. Two, high problem severity, early onset groups differed only on the cluster variable of negative affectivity (NA), but showed differences on antisocial personality characteristics, hypochondriasis, and coping motives for alcohol. The two low problem severity groups were distinguished by age of onset and positive affectivity (PA). The late onset, low PA group had a higher incidence of depression, a greater tendency to use substances in solitary contexts, and lower enhancement motives for alcohol compared to the early onset, high PA cluster. The four-cluster solution yielded more distinctions on external criteria than the two-cluster solution. Such temperament variation within both high and low severity substance abusers may be important for treatment planning.

    Congeners are substances, other than ethanol, that are produced during fermentation. Previous research found that the consumption of congener-rich drinks contributes to the severity of alcohol hangover. Methanol is such a congener that has been related to alcohol hangover. Therefore, the aim of this study was to examine the relationship between urine methanol concentration and alcohol hangover severity. N = 36 healthy social drinkers (22 females, 14 males), aged 18-30 years old, participated in a naturalistic study, comprising a hangover day and a control day (no alcohol consumed the previous day). N = 18 of them had regular hangovers (the hangover group), while the other N = 18 claimed to be hangover-immune (hangover-immune group). Overall hangover severity was assessed, and that of 23 individual hangover symptoms. Urine methanol concentrations on the hangover and control days were compared, and correlated to hangover (symptom) severity. Urine methanol concentration was significantly higher on hangover days compared to control days (p = 0.0001). No significant differences in urine methanol concentration were found between the hangover group and hangover-immune group. However, urine methanol concentration did not significantly correlate with overall hangover severity (r = -0.011, p = 0.948), nor with any of the individual hangover symptoms. These findings were observed also when analyzing the data separately for the hangover-immune group. In the hangover group, a significant correlation with urine methanol concentration was found only with vomiting (r = 0.489, p = 0.037). No significant correlation was observed between urine methanol concentration and hangover severity, nor with individual core hangover symptoms. Copyright © 2016 Elsevier Inc. All rights reserved.

    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.

    Understanding for whom moderated drinking is a viable, achievable, and sustainable goal among those with a range of alcohol use disorders (AUD) remains an important public health question. Despite common acceptance as severe risk factors, there is little empirical evidence to conclude whether co-occurring mental health disorders or drug dependence contribute to an individual’s inability to successfully moderate his drinking. Utilizing secondary data analysis, the purpose of this study was to identify predictors of moderation among both treatment seeking and non-treatment seeking, primarily alcohol dependent, problem drinking men who have sex with men (MSM), with an emphasis on the high risk factors psychiatric comorbidity and drug dependence. Problem drinkers (N=187) were assessed, provided feedback about their drinking, given the option to receive brief AUD treatment or change their drinking on their own, and then followed for 15 months. Findings revealed that neither psychiatric comorbidity or drug dependence predicted ability to achieve moderation when controlling for alcohol dependence severity. Those who were younger, more highly educated, and had more mild alcohol dependence were more likely to achieve moderated drinking. Impact of treatment on predictors is explored. Limitations of this study and arenas for future research are discussed. PMID:22201219

    The aim of this study was to identify groups of alcohol-dependent individuals differing in the severity of childhood physical, emotional and sexual abuse and to find the personality variables that discriminate between those groups. The study included 90 individuals dependent on alcohol. The following questionnaires were used: the Temperament and Character Inventory (TCI), the Coping Inventory (COPE), the Buss and Perry Aggression Questionnaire (BPAQ), Cattell's IPAT Anxiety Scale, and the Early Trauma Inventory (ETI). Two groups of subjects addicted to alcohol were identified: group 1 with high and group 2 with low childhood physical, emotional and sexual abuse indices. The subjects in Group 1 had significantly higher scores than the subjects in Group 2 on the TCI Temperament scales of NS and HA and lower scores on the TCI character scales of SD, C2 and C4. Group 1 subjects were significantly more likely than those from Group 2 to use avoidant coping strategies; they were also less likely to use problem-focused strategies and had significantly higher scores on general anxiety, overt anxiety, latent anxiety, level of aggression, physical aggression, hostility and anger. The higher severity of childhood physical, emotional and sexual abuse in alcoholics is associated with those personality traits that seem to be crucial for maintaining abstinence and the quality of cooperation in therapy.

    The COMBINE (combined pharmacotherapies and behavioral intervention) clinical trial recently evaluated the efficacy of pharmacotherapies, behavioral therapies, and their combinations for the treatment of alcohol dependence. Previously, the cost and cost-effectiveness of COMBINE have been studied. Policy makers, patients, and nonalcohol-dependent individuals may be concerned not only with alcohol treatment costs but also with the effect of alcohol interventions on broader social costs and outcomes. To estimate the sum of treatment costs plus the costs of health care utilization, arrests, and motor vehicle accidents for the 9 treatments in COMBINE 3 years postrandomization. A cost study based on a randomized controlled clinical trial. : The study involved 786 participants 3 years postrandomization. Multivariate results show no significant differences in mean costs between any of the treatment arms as compared with medical management (MM) + placebo for the 3-year postrandomization sample. The median costs of MM + acamprosate, MM + naltrexone, MM + acamprosate + naltrexone, and MM + acamprosate + combined behavioral intervention were significantly lower than the median cost for MM + placebo. The results show that social cost savings are generated relative to MM + placebo by 3 years postrandomization, and the magnitude of these cost savings is greater than the costs of the COMBINE treatment received 3 years prior. Our study suggests that several alcohol treatments may indeed lead to reduced median social costs associated with health care, arrests, and motor vehicle accidents.

    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.

    Background Both a family history of alcoholism and migration-related factors like U.S. versus 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 U.S. Methods Data were from the wave 1 and wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Subjects self-identified Hispanic ethnicity (N = 4,122; n = 1,784 first, n = 1,169 second, and n = 1,169 third or later generation) and reported ever consuming 12 or more drinks in a one-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. Results 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 U.S., 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. Conclusions Familial alcoholism interacted with generational status in predicting alcohol dependence symptoms in U.S. 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. PMID:27681653

    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. All rights

    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.

  11. Amphetamine Dependence and Co-Morbid Alcohol Abuse: Associations to Brain Cortical Thickness

    PubMed Central

    2010-01-01

    Background Long-term amphetamine and methamphetamine dependence has been linked to cerebral blood perfusion, metabolic, and white matter abnormalities. Several studies have linked methamphetamine abuse to cortical grey matter reduction, though with divergent findings. Few publications investigate unmethylated amphetamine's potential effects on cortical grey matter. This work investigated if amphetamine dependent patients showed reduced cortical grey matter thickness. Subjects were 40 amphetamine dependent subjects and 40 healthy controls. While all subjects were recruited to be free of alcohol dependence, structured clinical interviews revealed significant patterns of alcohol use in the patients. Structural magnetic resonance brain images were obtained from the subjects using a 1.5 Tesla GE Signa machine. Brain cortical thickness was measured with submillimeter precision at multiple finely spaced cortical locations using semi-automated post-processing (FreeSurfer). Contrast analysis of a general linear model was used to test for differences between the two groups at each cortical location. In addition to contrasting patients with controls, a number of analyses sought to identify possible confounding effects from alcohol. Results No significant cortical thickness differences were observed between the full patient group and controls, nor between non-drinking patients and controls. Patients with a history of co-morbid heavy alcohol use (n = 29) showed reductions in the superior-frontal right hemisphere and pre-central left hemisphere when compared to healthy controls (n = 40). Conclusions Amphetamine usage was associated with reduced cortical thickness only in patients co-morbid for heavy alcohol use. Since cortical thickness is but one measure of brain structure and does not capture brain function, further studies of brain structure and function in amphetamine dependence are warranted.

    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.

    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. 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. 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. 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.

    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.

Our results do not support the hypothesis.

    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.

    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.

    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.

    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.

    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.

    Several lines of evidence suggest that classic (5HT2A agonist) hallucinogens have clinically relevant effects in alcohol and drug addiction. Although recent studies have investigated the effects of psilocybin in various populations, there have been no studies on the efficacy of psilocybin for alcohol dependence. We conducted a single-group proof-of-concept study to quantify acute effects of psilocybin in alcohol-dependent participants and to provide preliminary outcome and safety data. Ten volunteers with DSM-IV alcohol dependence received orally administered psilocybin in one or two supervised sessions in addition to Motivational Enhancement Therapy and therapy sessions devoted to preparation for and debriefing from the psilocybin sessions. Participants' responses to psilocybin were qualitatively similar to those described in other populations. Abstinence did not increase significantly in the first 4 weeks of treatment (when participants had not yet received psilocybin), but increased significantly following psilocybin administration (p < 0.05). Gains were largely maintained at follow-up to 36 weeks. The intensity of effects in the first psilocybin session (at week 4) strongly predicted change in drinking during weeks 5-8 (r = 0.76 to r = 0.89) and also predicted decreases in craving and increases in abstinence self-efficacy during week 5. There were no significant treatment-related adverse events. These preliminary findings provide a strong rationale for controlled trials with larger samples to investigate efficacy and mechanisms.

    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

    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

    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.

    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.

    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.

    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

    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.

    To propose methods for the inclusion of within-family external effects in clinical and economic evaluations. To demonstrate the extent of bias due to the exclusion of within-family external effects when measuring the relative performance of interventions for problem drinking and alcohol dependence. The timing and magnitude of treatment effects are modified to accommodate the external health-related quality of life impact of having a problem or dependent drinker in the family home. The inclusion of within-family external effects reduces cost per QALY estimates of interventions for problem drinking and alcohol dependence thereby improving the performance of all evaluated interventions. In addition, the inclusion of within-family external effects improves the relative performance of interventions targeted at those with moderate-to-severe alcohol dependence as compared to interventions targeted at less severe alcohol problems. Failure to take account of external effects in clinical and economic evaluations results in an uneven playing field. Interventions with readily quantifiable health benefits (where social costs and benefits are predominantly comprised of private costs and benefits) are at a distinct advantage when competing for public funding against interventions with quantitatively important external effects.

    Ethanol blocks N-methyl-d-aspartic acid (NMDA) glutamate receptors. Increased NMDA receptor function may contribute to motivational disturbances that contribute to alcoholism. The authors assessed whether the NMDA receptor antagonist memantine reduces cue-induced alcohol craving and produces ethanol-like subjective effects. Thirty-eight alcohol-dependent inpatients participated in three daylong testing sessions in a randomized order under double-blind conditions. On each test day, subjects received 20 mg of memantine, 40 mg of memantine, or placebo, and subjective responses to treatment were assessed. The level of alcohol craving was assessed before and after exposure to an alcohol cue. Memantine did not stimulate alcohol craving before exposure to an alcohol cue, and it attenuated alcohol cue-induced craving in a dose-related fashion. It produced dose-related ethanol-like effects without adverse cognitive or behavioral effects. These data support further exploration of whether well-tolerated NMDA receptor antagonists might have a role in the treatment of alcoholism.

  13. Life stress in adolescence predicts early adult reward-related brain function and alcohol dependence

    Stressful life events increase vulnerability to problematic alcohol use, and they may do this by disrupting reward-related neural circuitry. This is particularly relevant for adolescents because alcohol use rises sharply after mid-adolescence and alcohol abuse peaks at age 20. Adolescents also report more stressors compared with children, and neural reward circuitry may be especially vulnerable to stressors during adolescence because of prefrontal cortex remodeling. Using a large sample of male participants in a longitudinal functional magnetic resonance imaging study (N = 157), we evaluated whether cumulative stressful life events between the ages of 15 and 18 were associated with reward-related brain function and problematic alcohol use at age 20 years. Higher cumulative stressful life events during adolescence were associated with decreased response in the medial prefrontal cortex (mPFC) during monetary reward anticipation and following the receipt of monetary rewards. Stress-related decreases in mPFC response during reward anticipation and following rewarding outcomes were associated with the severity of alcohol dependence. Furthermore, mPFC response mediated the association between stressful life events and later symptoms of alcohol dependence. These data are consistent with neurobiological models of addiction that propose that stressors during adolescence increase risk for problematic alcohol use by disrupting reward circuit function.

    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.

    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.

    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.

    To investigate the current purchasing behaviours of a group of dependent drinkers and their potential response to future increases in the price of alcohol. 115 clients undergoing medical detoxification completed an anonymous survey about their daily alcohol consumption, its cost, their response to potential price increases and strategies previously used when unable to afford alcohol. Mean and median number of standard drinks consumed per day was 24, at a median cost of $25 NZD (95%CI $22, $30). Thirty-six per cent (95%CI 26%, 46%) of the group bought alcohol at $1 or less per standard drink, and the median number of drinks consumed per day (30) by this group was significantly higher (p=0.0028) than the rest of the sample (22.5). The most common strategy used if no money was available to purchase alcohol was to forgo essentials. If facing a potential price rise, 77% (95%CI 69%, 85%) would switch wholly or partially to a cheaper product and 13% (95%CI 8%, 21%) would cut down their drinking. Although the majority of our group would be financially impacted by an increase in the minimum price per standard drink, any potential impacts would be most significant in those buying the cheapest alcohol (who also drink the most), suggesting that minimum pricing may be an important harm minimisation strategy in this group. A minimum price per standard drink would limit the possibility of switching to an alternate cheaper product and likely result in an overall reduction in alcohol consumption in this group. Stealing alcohol, or the use of non-beverage alcohol, were seldom reported as previous strategies used in response to unaffordable alcohol and fears of such are not valid reasons for rejecting minimum pricing to reduce general population consumption.

    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.

    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

    Most treatment programs for alcohol dependence have prioritized alcohol abstinence as the primary treatment goal. However, abstinence-based goals are not always considered desirable or attainable by more severely affected populations, such as chronically homeless people with alcohol dependence. Because these individuals comprise a multimorbid and high-utilizing population, they are in need of more focused research attention that elucidates their preferred treatment goals. The aim of this secondary study was therefore to qualitatively and quantitatively document participant-generated treatment goals. Participants were currently or formerly chronically homeless individuals (N=31) with alcohol dependence who participated in a pilot of extended-release naltrexone and harm-reduction counseling. Throughout the treatment period, study interventionists elicited participants’ goals and recorded them on an open-ended grid. In subsequent weeks, progress towards and achievement of goals was obtained via self-report and recorded by study interventionists. Conventional content analysis was performed to classify participant-generated treatment goals. Representation of the three top categories remained stable over the course of treatment. In the order of their frequency, they included drinking-related goals, quality-of-life goals and health-related goals. Within the category of drinking-related goals, participants consistently endorsed reducing drinking and alcohol-related consequences ahead of abstinence-based goals. Quantitative analyses indicated participants generated an increasing number of goals over the course of treatment. Proportions of goals achieved and progressed toward kept pace with this increase. Findings confirmed hypotheses that chronically homeless people with alcohol dependence can independently generate and achieve treatment goals toward alcohol harm reduction and quality-of-life improvement.

    Background The frequency of alcoholic liver disease (ALD), including alcoholic steatosis, hepatitis and cirrhosis, varies significantly by ethnicity. Methods With the goal to assess the role of ethnicity in determining the age of onset and severity of ALD and to compare the risk factors for its progression among ethnic groups, we conducted a retrospective chart review of all patients with ALD who were admitted or were followed as outpatients at University of California Davis Medical Center between 2002 and 2010. After excluding HBsAg and HIV positive subjects, we reviewed the charts of 791 ALD patients including 130 with alcoholic fatty liver, 154 with alcoholic hepatitis, and 507 with alcoholic cirrhosis. Results When controlling for all variables in the model, Hispanic patients presented at significantly 4-10 years younger ages than White/Caucasian patients, in each of the three disease severity categories and the results were confirmed after excluding HCV Ab/RNA positive subjects. There were more obese Hispanic patients than White/Caucasian patients, whereas the proportion of patients with hepatitis C was significantly greater in African/American subjects with alcoholic hepatitis and the proportion of patients with diabetes mellitus was significantly lower in White/Caucasian subjects than in Hispanic subjects with cirrhosis. The proportion of subjects with severe alcoholic hepatitis was similar in Hispanic and White/Caucasian patients, but lower in African/American subjects. Conclusion Ethnicity is a major factor affecting the age and severity of presentation of different subtypes of ALD. PMID:25702770

    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.

    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.

    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.

    The present study investigated the genetic contribution to alcohol dependence (AD) using genome-wide association data from three German samples. These comprised patients with: (i) AD; (ii) chronic alcoholic pancreatitis (ACP); and (iii) alcohol-related liver cirrhosis (ALC). Single marker, gene-based, and pathway analyses were conducted. A significant association was detected for the ADH1B locus in a gene-based approach (puncorrected = 1.2 × 10−6; pcorrected = 0.020). This was driven by the AD subsample. No association with ADH1B was found in the combined ACP + ALC sample. On first inspection, this seems surprising, since ADH1B is a robustly replicated risk gene for AD and may therefore be expected to be associated also with subgroups of AD patients. The negative finding in the ACP + ALC sample, however, may reflect genetic stratification as well as random fluctuation of allele frequencies in the cases and controls, demonstrating the importance of large samples in which the phenotype is well assessed.

    The influence of Pavlovian conditioned stimuli on ongoing behavior may contribute to explaining how alcohol cues stimulate drug seeking and intake. Using a Pavlovian-instrumental transfer task, we investigated the effects of alcohol-related cues on approach behavior (i.e., instrumental response behavior) and its neural correlates, and related both to the relapse after detoxification in alcohol-dependent patients. Thirty-one recently detoxified alcohol-dependent patients and 24 healthy controls underwent instrumental training, where approach or non-approach towards initially neutral stimuli was reinforced by monetary incentives. Approach behavior was tested during extinction with either alcohol-related or neutral stimuli (as Pavlovian cues) presented in the background during functional magnetic resonance imaging (fMRI). Patients were subsequently followed up for 6 months. We observed that alcohol-related background stimuli inhibited the approach behavior in detoxified alcohol-dependent patients (t = - 3.86, p < .001), but not in healthy controls (t = - 0.92, p = .36). This behavioral inhibition was associated with neural activation in the nucleus accumbens (NAcc) (t (30)  = 2.06, p < .05). Interestingly, both the effects were only present in subsequent abstainers, but not relapsers and in those with mild but not severe dependence. Our data show that alcohol-related cues can acquire inhibitory behavioral features typical of aversive stimuli despite being accompanied by a stronger NAcc activation, suggesting salience attribution. The fact that these findings are restricted to abstinence and milder illness suggests that they may be potential resilience factors. LeAD study, http://www.lead-studie.de , NCT01679145.

    The purpose of this study was to examine relationships between genetic markers of central serotonin (5-HT) and dopamine function, and risk for post-treatment relapse, in a sample of alcohol-dependent patients. The study included 154 patients from addiction treatment programs in Poland, who met DSM-IV criteria for alcohol dependence. After assessing demographics, severity of alcohol use, suicidality, impulsivity, depression, hopelessness, and severity of alcohol use at baseline, patients were followed for approximately 1 year to evaluate treatment outcomes. Genetic polymorphisms in several genes (TPH2, SLC6A4, HTR1A, HTR2A, COMT, and BDNF) were tested as predictors of relapse (defined as any drinking during follow-up) while controlling for baseline measures. Of 154 eligible patients, 123 (80%) completed follow-up and 48% (n = 59) of these individuals relapsed. Patients with the Val allele in the Val66Met BDNF polymorphism and the Met allele in the Val158Met COMT polymorphism were more likely to relapse. Only the BDNF Val/Val genotype predicted post-treatment relapse [odds ratio (OR) = 2.62; p = 0.019], and time to relapse (OR = 2.57; p = 0.002), after adjusting for baseline measures and other significant genetic markers. When the analysis was restricted to patients with a family history of alcohol dependence (n = 73), the associations between the BDNF Val/Val genotype and relapse (OR = 5.76, p = 0.0045) and time to relapse (hazard ratio = 4.93, p = 0.001) were even stronger. The Val66Met BDNF gene polymorphism was associated with a higher risk and earlier occurrence of relapse among patients treated for alcohol dependence. The study suggests a relationship between genetic markers and treatment outcomes in alcohol dependence. Because a large number of statistical tests were conducted for this study and the literature on genetics and relapse is so novel, the results should be considered as hypothesis generating and need to be replicated in independent studies.

    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.

    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.

    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.

    Increasing attention to the importance of saliva testing is not surprising because smoking and alcohol drinking act synergistically on oral tissues, and their metabolite levels, e.g., acetaldehyde, are much higher in saliva than in blood. The activity of salivary alcohol dehydrogenase (ADH) comes from oral microbiota, mucosa, and salivary glands. The purpose of this study was to investigate the involvement of ADH in the oral health pathology of smoking (AS) and non-smoking (ANS) alcohol-dependent males. The results indicated that the AS group had a more significant and longer duration (until the 30th day of alcohol abstinence) decrease in ADH activity and output than the ANS group (until the 15th day of alcohol abstinence) compared to controls (social drinkers; C). The decreased salivary flow (SF) in alcoholics was observed longer in the ANS group (until the 30th day of alcohol abstinence), whereas in the AS group SF normalized at the 15th day, probably due to the irritating effect of tobacco smoke on the oral mucosa. Because saliva was centrifuged to remove cells and debris (including microbial cells), the detected salivary ADH activity was derived from salivary glands and/or oral mucosa. A more profound and longer decrease in ADH activity/output in smoking than non-smoking alcoholics was likely due to the damaged salivary glands and/or oral mucosa, caused by the synergistic effect of alcohol drinking and smoking. The lower values of salivary ADH in smoking than non-smoking alcoholics might also be partly due to the reversed/inhibited ADH reaction by high levels of accumulated acetaldehyde.

    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.

    The purpose of this study was to evaluate the effect of chronic alcohol intoxication and smoking on the concentration and output of salivary lysozyme. Thirty seven men participated in the study, including 17 male smoking alcohol-dependent patients after chronic alcohol intoxication (AS), and 20 control non-smoking male social drinkers (CNS) with no history of alcohol abuse or smoking. The level of lysozyme was assessed by the radial immunodiffusion method. Significantly lower lysozyme output in the AS group compared to the CNS group was found. Moreover, gingival index was significantly higher in AS than in the CNS group. It appeared that the reduced salivary lysozyme output was more likely the result of ethanol action than smoking. In conclusion, persons addicted to alcohol and nicotine have a poorer periodontal status than non-smoking social drinkers, which may partially be due to the diminished protective effects of lysozyme present in the saliva.

    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

    We examined the effect of the quality of primary care-based chronic disease management (CDM) for alcohol and/or other drug (AOD) dependence on addiction outcomes. We assessed quality using (1) a visit frequency based measure and (2) a self-reported assessment measuring alignment with the chronic care model. The visit frequency based measure had no significant association with addiction outcomes. The self-reported measure of care-when care was at a CDM clinic-was associated with lower drug addiction severity. The self-reported assessment of care from any healthcare source (CDM clinic or elsewhere) was associated with lower alcohol addiction severity and abstinence. These findings suggest that high quality CDM for AOD dependence may improve addiction outcomes. Quality measures based upon alignment with the chronic care model may better capture features of effective CDM care than a visit frequency measure. Copyright © 2012 Elsevier Inc.

    To improve the results of treatment of children with severe alcohol poisoning as a result of investigation of water sectors of the body. The study included 54 patients aged from 13 to 15 years with a diagnosis of acute severe alcohol poisoning. All patients were divided into three groups. At the initial examination was determined the concentration of alcohol in saliva using Express-test "Alkoskan." Bioimpedance analysis was performed; water sectors of the body were investigated by analyzer of the balance of water sectors ABC-01 "Medass." The study was conducted at the time of admission, after 12, 24 and 48 hours. In severe alcohol poisoning at the time of admission, it was revealed a reduction of the fluid in all studied sectors. The most effective compensation of liquid was observed in groups, where was used combination therapy included intravenous fluids based 4.0 ml/kg/hour. The treatment of severe alcohol poisoning should include fluid resuscitation about 4 ml/kg/hour. This capacity of medical care give the ability to correct adequately the water-sectoral disturbances already in the first 12 hours of hospitalization, and the inclusion to the basic therapy reamberine can contribute more effective replenishment of water sectors.

    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.

    Background: Alcohol and hypertriglyceridemia (HTG) are among the most common causes of acute pancreatitis (AP) after gallstones. However, differences in severity at the time of presentation and outcomes have not been well-studied. Objective: The aim of this study is to assess the differences between severity at presentation and outcomes of AP of hypertriglyceridemic and alcoholic origins. Materials and Methods: A retrospective review of 177 patients who were discharged with diagnosis of AP was performed. Severity at presentation was identified by the presence of systemic inflammatory response syndrome, bedside index for severity in AP (BISAP) score, and Balthazar index. Outcomes were measured by the length of stay, intensive care unit care, surgical intervention, and mortality. Results: We found 147 patients with alcoholic pancreatitis and 30 patients with hypertriglyceridemic pancreatitis. A larger percentage of hypertriglyceridemic pancreatitis patients (23.33%) had a BISAP score of ≥2 compared to the alcoholic group (12.24%). Only 32.65% of the patients with alcoholic pancreatitis but 60% of the patients with hypertriglyceridemic pancreatitis had the presence of systemic inflammatory response syndrome (SIRS) at admission (P = 0.0067). There were 73.34% hypertriglyceridemic pancreatits patients and only 40.28% alcoholic pancreatitis patients with Balthazar index C or greater, suggesting a higher disease burden at admission for hypertriglyceridemic pancreatitis patients (P = 0.0047). There was a statistically significant difference in the relative number of hypertriglyceridemic and alcoholic pancreatitis patients receiving intensive care (P = 0.00030) and in receiving surgical interventions related to pancreatitis (P = 0.016). Conclusion: Our study found that patients with hypertriglyceridemic pancreatitis have a greater severity of disease and they experience less favorable outcomes than patients with alcoholic pancreatitis.

    The relationship between the use of alcohol and aggression is complex and represents major public health issues. Delving into the nature of this association is vital, since various underlying factors may contribute to the expression of aggression. This study examined trait aggression by assessing correlates and, subsequently, the unique contribution of alcohol craving, and dysfunctional impulsivity, by means of correlational and mediational analyses. Forty inpatient detoxified alcohol-dependent patients were recruited. These participants completed the Desire for Alcohol Questionnaire (DAQ), Dickman Impulsivity Inventory (DII), and the Aggression Questionnaire (AQ). The findings indicated that aggression, dysfunctional impulsivity, and alcohol craving were all positively intercorrelated. The association between dysfunctional impulsivity and aggression was robust. The mediational analyses yielded that craving partially mediated this relationship, although not very substantial. It was shown that impulsivity, as a personality characteristic, is strongly associated with aggressive behaviors, whereby the impact of craving on the relationship between impulsivity and trait aggression in alcohol-dependent inpatients was weak. Since it has been posited that factors such as impulsivity and craving may contribute to the lucid association between substance use and aggression, these findings mirror previous research on stimulant users and, subsequently, substantiates that craving exerts only a minor weight on the strong impulsivity-aggression relationship.

The study was performed in two stages: an initial screening (n = 8335) for alcohol consumption, followed by a structured psychiatric interview (n = 1054). The Masculinity/Femininity-Questionnaire was used as an indicator of gender identity. The final study group included 836 women. Leadership, caring, self-assertiveness and emotionality were dimensions of gender identity found in a factor analysis. Low self-assertiveness, high emotionality and to some extent low leadership were associated with increased odds for having bipolar disorders, severe anxiety disorders and alcohol dependence and misuse. Low self-assertiveness and high emotionality were not only associated with alcohol dependence and misuse, but also with high episodic drinking. There was an association between some of the dimensions of gender identity and psychiatric disorders and alcohol consumption. Further attention is needed in both clinical work and research.

    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.

    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.

    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.

    Data in gender differences in aggression among alcohol and drug dependent subjects are lacking, and no published data are available about gender differences among various subtypes of substance using populations. The goal of this cross-sectional study was to investigate gender differences with regard to types of trait aggression in substance dependent young populations (age: 20-35 years) compared to the general population. Subjects were selected from two clinical samples with a diagnosis of alcohol and drug dependence as well as from a representative sample of the general population. Trait aggression was measured by the four individual subscales of the Buss Perry Aggression Questionnaire (physical-PA, verbal aggression-VA, hostility-H and anger AN) whereas alcohol and drug use were characterized by the AUDIT and EuroADAD scales, respectively. Alcohol and drug dependent subjects showed higher severity on all four subscales of trait aggression compared to the general population. The male-female difference was the highest in the cannabis group. General Linear Model analysis for PA indicated a significant main effect of gender (higher PA for males, p=0.034) with no interaction between substance dependence and gender. For VA, no main effect or interaction for gender was found. Effect sizes for gender difference indicated that while males and females were similar in the control group in the severity in H and A, the level of H and AN was substantially higher in females than in males in the clinical group. These differences between the two genders reached statistical significance in the marijuana group, where female subjects showed a significantly higher severity in these two domains. Compared to the normal sample chronic substance use is associated with higher scores on certain factors of trait aggression, including hostility and anger, in females than in males. Our data suggest that aggression in substance dependent females is more provocable by chronic use of alcohol and

    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

    Patients' personal investment and readiness to change have proved to be a prerequisite for the successful treatment of alcohol addiction. The aim of this study was to determine the contribution of cognitive functions to the motivation process to abandon maladjusted behavior in favor of a healthier lifestyle. An adapted version of the "readiness to change" questionnaire was completed by 31 alcohol-dependent patients after detoxification and at alcohol treatment entry. This tool is designed to assess the 3 main stages of motivation to change regarding alcohol consumption: precontemplation (substance abuse and no intention to stop drinking), contemplation (strong intention to change habits but ambivalent behavior), and action (cessation of excessive alcohol consumption and behavioral changes for healthier habits) stages. Patients and 37 healthy controls also underwent an extensive neuropsychological battery including episodic memory, metamemory, executive functions, and decision-making assessment. When alcohol-dependent patients were considered as a group, the mean score on the action subscale was significantly higher than the precontemplation and contemplation ones. Nevertheless, when the stage of change reached by each patient was considered individually, we found that some alcohol-dependent patients were still in the earlier precontemplation and contemplation stages. Stepwise regression analysis revealed links between impaired memory and executive functions and low motivation, and between good decision-making skills and high motivation. Our results suggest that a set of complementary cognitive abilities is needed to achieve awareness and resolve ambivalence toward alcohol addiction, which is essential for activating the desire to change problematic behavior.

    2017-05-01

    Defense mechanisms have been seen to greatly change over time and across different definitions made by different theoretical currents. Recently with the definition provided by the DSM IV, defense mechanisms have integrated the concept of coping as a defensive factor. These mechanisms are no longer considered just through a psychodynamic approach but also through a cognitive and behavioral one. In recent years, new theories have therefore integrated these two components of the defensive operation. According to Chabrol and Callahan (2013), defense mechanisms precede coping strategies. In individuals with psychopathological disorders, these authors indicate a relative stability of these mechanisms. Also, we asked about the presence of unique characteristics among people with alcohol dependence. Indeed, studies conducted with people with alcohol dependence highlight the presence of a neurotic defense style and some highly immature defenses (projection, acting out, splitting and somatization). In terms of coping strategies, persons with alcohol dependence preferentially use avoidant strategies and strategies focused on emotion. However, although several studies have been conducted to assess coping strategies and defense styles within a population of individuals with an alcohol problem, at the present time none of them has taken into account all these aspects of defense mechanisms. The aim of this study is therefore to study the defenses and defense styles and coping strategies in an alcohol-dependent population. This multicenter study (3 CHU, 1 center of supportive care and prevention in addiction and 1 clinic) received a favorable opinion of an Institutional Review Board (IRB Registration #: 00001072). Eighty alcohol-dependent individuals responded to a questionnaire assessing sociodemographic characteristics and elements related to the course of consumption. Coping strategies were assessed by means of a questionnaire validated in French: the Brief Cope. The Defense

    Sleep-related complaints are widely prevalent in those with alcohol dependence (AD). AD is associated not only with insomnia, but also with multiple sleep-related disorders as a growing body of literature has demonstrated. This article will review the various aspects of insomnia associated with AD. In addition, the association of AD with other sleep-related disorders will be briefly reviewed. The association of AD with insomnia is bidirectional in nature. The etiopathogenesis of insomnia has demonstrated multiple associations and is an active focus of research. Treatment with cognitive behavioral therapy for insomnia is showing promise as an optimal intervention. In addition, AD may be associated with circadian abnormalities, short sleep duration, obstructive sleep apnea, and sleep-related movement disorder. The burgeoning knowledge on insomnia associated with moderate-to-severe alcohol use disorder has expanded our understanding of its underlying neurobiology, clinical features, and treatment options.

    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

    Objectives The present study sought to: (a) categorize youths into groups based on their level of alcohol use and number of symptoms of alcohol abuse and dependence defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), and (b) examine whether these categories were associated with other problem behaviors in which youths engage (marijuana use, sexual intercourse, and having been arrested or having trouble with the law). Methods The study is based on a cross-sectional survey administered to 972 school-based youths from one middle school and one high school in San Juan, Puerto Rico. Youths were categorized based on their alcohol use and alcohol problems. These categories were then examined for associations with lifetime marijuana use, lifetime sexual intercourse, and having been arrested or having had trouble with the law in the past year. The original eight categories of alcohol use were collapsed into six categories based on the results. Results For virtually every group characterized by higher severity of alcohol use and alcohol problems, researchers found an increasing prevalence of marijuana use in their lifetimes, increasing odds of sexual intercourse in their lifetimes, and having had trouble with the law in the past year. Conclusions Knowing about variations in alcohol use and alcohol problems may be instrumental in measuring the degree to which youths may also be engaging in a range of other elevated risk behaviors and a progression to more serious forms of alcohol and drug use.

    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.

    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.

    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.

To determine if gabapentin, a widely prescribed generic calcium channel/γ-aminobutyric acid-modulating medication, increases rates of sustained abstinence and no heavy drinking and decreases alcohol-related insomnia, dysphoria, and craving, in a dose-dependent manner. A 12-week, double-blind, placebo-controlled, randomized dose-ranging trial of 150 men and women older than 18 years with current alcohol dependence, conducted from 2004 through 2010 at a single-site, outpatient clinical research facility adjoining a general medical hospital. Oral gabapentin (dosages of 0 [placebo], 900 mg, or 1800 mg/d) and concomitant manual-guided counseling. Rates of complete abstinence and no heavy drinking (coprimary) and changes in mood, sleep, and craving (secondary) over the 12-week study. RESULTS Gabapentin significantly improved the rates of abstinence and no heavy drinking. The abstinence rate was 4.1% (95% CI, 1.1%-13.7%) in the placebo group, 11.1% (95% CI, 5.2%-22.2%) in the 900-mg group, and 17.0% (95% CI, 8.9%-30.1%) in the 1800-mg group (P = .04 for linear dose effect; number needed to treat [NNT] = 8 for 1800 mg). The no heavy drinking rate was 22.5% (95% CI, 13.6%-37.2%) in the placebo group, 29.6% (95% CI, 19.1%-42.8%) in the 900-mg group, and 44.7% (95% CI, 31.4%-58.8%) in the 1800-mg group (P = .02 for linear dose effect; NNT = 5 for 1800 mg). Similar linear dose effects were obtained with measures of mood (F2 = 7.37; P = .001), sleep (F2 = 136; P < .001), and craving (F2 = 3.56; P = .03). There were no serious drug-related adverse events, and terminations owing to adverse events (9 of 150 participants), time in the study (mean [SD], 9.1 [3.8] weeks), and rate of study completion (85 of 150 participants) did not differ among groups. Gabapentin (particularly the 1800-mg dosage) was effective in treating alcohol dependence and relapse-related symptoms of insomnia

    High-dose baclofen, i.e., 300 mg/d or more, has recently emerged as a strategy for treating alcohol dependence. The impact that the co-exposure of large amounts of alcohol and baclofen has on sedation is unclear. In a prospective cohort of 253 subjects with alcohol dependence, we collected daily alcohol and baclofen doses across the first year of baclofen treatment and the monthly maximum subjective sedation experienced by each patient (0-10 visual analog scale). For each patient-month, we determined the average weekly alcohol consumption (AWAC; standard-drinks/week) and the maximum daily dose of baclofen (DDB; mg/d). The occurrence of an episode of major sedation (EMS) during a patient-month was defined as a sedation score ≥7. The relationship between the EMS occurrence and the concurrent AWAC and DDB was investigated using a generalized estimating equation model. In total, 1528 patient-months were compiled (70 with an EMS). Univariate analyses demonstrated that the rate of patient-month to EMS increased gradually with AWAC (p<0.001), from 0.9% for AWAC=0 to 9.4% for AWAC >35. There was also a significant gradual risk for EMS associated with DDB (<0.001). Multivariate analysis demonstrated a significant interaction between DDB and AWAC on EMS risk (p=0.047). Each 20mg/d increase in DDB was associated with an OR of EMS in AWAC >35 of 1.22 (95%CI, 1.08-1.38) versus 1.11 (95%CI, 0.96-1.29) in AWAC=1-35, and 0.95 (95%CI, 0.76-1.19) in AWAC=0. The level of sedation observed in patients using baclofen for alcohol dependence appears to directly depend on the immediate doses of both the baclofen and the alcohol.

    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.

    Background Rate of nicotine metabolism is an important factor influencing cigarette smoking behavior, dependence, and efficacy of nicotine replacement therapy. The current study examined the hypothesis that chronic alcohol abuse can accelerate the rate of nicotine metabolism. Nicotine metabolite ratio (NMR, a biomarker for rate of nicotine metabolism) and patterns of nicotine metabolites were assessed at three time points after alcohol cessation. Methods Participants were 22 Caucasian men randomly selected from a sample of 165 smokers entering a 7-week alcohol dependence treatment program in Poland. Data were collected at three time points: baseline (week 1, after acute alcohol detoxification), week 4, and week 7. Urine was analyzed for nicotine and metabolites and used to determine the nicotine metabolite ratio (NMR, a biomarker for rate of nicotine metabolism), and total nicotine equivalents (TNE, a biomarker for total daily nicotine exposure). Results and conclusions There was a significant decrease in urine NMR over the 7 weeks after alcohol abstinence (F(2,42)=18.83, p<0.001), indicating a decrease in rate of nicotine metabolism. On average NMR decreased 50.0% from baseline to week 7 (9.6 ± 1.3 vs. 4.1 ± 0.6). There was no change in urine TNE across the three sessions, indicating no change daily nicotine intake. The results support the idea that chronic alcohol abuse may increases the rate of nicotine metabolism, which then decreases over time after alcohol cessation. This information may help to inform future smoking cessation interventions in this population. PMID:27107849

    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.

    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.

    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

    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

    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. 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. 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. 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.

    The location of the hydroxyl group in monohydroxy alcohols greatly affects the temperature dependence of the liquid structure due to hydrogen bonding. Temperature-dependent self-diffusion coefficients, fluidity (the inverse of viscosity), dielectric constant, and density have been measured for several 1-alcohols and 3-alcohols with varying alkyl chain lengths. The data are modeled using the compensated Arrhenius formalism (CAF). The CAF follows a modified transition state theory using an Arrhenius-like expression to describe the transport property, which consists of a Boltzmann factor containing an energy of activation, Ea, and an exponential prefactor containing the temperature-dependent solution dielectric constant, εs(T). Both 1- and 3-alcohols show the Ea of diffusion coefficients (approximately 43 kJ mol(-1)) is higher than the Ea of fluidity (approximately 35 kJ mol(-1)). The temperature dependence of the exponential prefactor in these associated liquids is explained using the dielectric constant and the Kirkwood-Frölich correlation factor, gk. It is argued that the dielectric constant must be used to account for the additional temperature dependence due to variations in the liquid structure (e.g., hydrogen bonding) for the CAF to accurately model the transport property.

    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

    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.

    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.

    Unhealthy alcohol use predisposes to multiple conditions that frequently result in critical illness and is present in up to one-third of patients admitted to a medical intensive care unit (ICU). We sought to determine the baseline readiness to change in medical ICU patients with unhealthy alcohol use and hypothesized that the severity of acute illness would be independently associated with higher scores on readiness to change scales. We further sought to determine whether this effect is modified by the severity of unhealthy alcohol use. We performed a cross-sectional observational study of current regular drinkers in 3 medical ICUs. The Alcohol Use Disorders Identification Test was used to differentiate low-risk and unhealthy alcohol use and further categorize patients into risky alcohol use or an alcohol use disorder. The severity of a patient's acute illness was assessed by calculating the Acute Physiologic and Chronic Health Evaluation II (APACHE II) score at the time of admission to the medical ICU. Readiness to change was assessed using standardized questionnaires. Of 101 medical ICU patients who were enrolled, 65 met the criteria for unhealthy alcohol use. The association between the severity of acute illness and readiness to change depended on the instrument used. A higher severity of illness measured by APACHE II score was an independent predictor of readiness to change as assessed by the Stages of Change Readiness and Treatment Eagerness Scale (Taking Action scale; p < 0.01). When a visual analog scale was used to assess readiness to change, there was a significant association with severity of acute illness (p < 0.01) that was modified by the severity of unhealthy alcohol use (p = 0.04 for interaction term). Medical ICU patients represent a population where brief interventions require further study. Studies of brief intervention should account for the severity of acute illness and the severity of unhealthy alcohol use as potential effect modifiers

    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.

    Medication for the treatment of alcoholism is currently not particularly robust. Neuroimaging techniques might predict which medications could be useful in the treatment of alcohol dependence. To explore the effect of naltrexone, ondansetron hydrochloride, or the combination of these medications on cue-induced craving and ventral striatum activation. Functional brain imaging was conducted during alcohol cue presentation. Participants were recruited from the general community following media advertisement. Experimental procedures were performed in the magnetic resonance imaging suite of a major training hospital and medical research institute. Ninety non-treatment-seeking alcohol-dependent (by DSM-IV criteria) and 17 social drinking (< 14 drinks per week) paid volunteers recruited through advertisements at an academic center. A taste of alcohol and a series of alcohol-related pictures, neutral beverage pictures, and visual control images were provided to volunteers after 7 days of double-blind randomly assigned daily dosing with 50 mg of naltrexone (n = 23), 0.50 mg of ondansetron hydrochloride (n = 23), the combination of the 2 medications (n = 20), or matching placebos (n = 24). Difference in brain blood oxygen level-dependent magnetic resonance when viewing alcohol pictures vs neutral beverage pictures with a particular focus on ventral striatum activity comparison across medication groups. Self-ratings of alcohol craving. The combination treatment decreased craving for alcohol. Naltrexone with (P = .02) or without (P = .049) ondansetron decreased alcohol cue-induced activation of the ventral striatum. Ondansetron by itself was similar to naltrexone and the combination in the overall analysis but intermediate in a region-specific analysis. Consistent with animal data that suggest that both naltrexone and ondansetron reduce alcohol-stimulated dopamine output in the ventral striatum, the current study found evidence that these medications, alone or in combination

    The physician's duty to preserve patient confidentiality is challenged when doing so may endanger third parties. We present the case of a bus driver whose alcohol dependence raised concerns of a risk not only to his own health and safety, but to public safety as well. We first examine the legal and ethical obligations to report his alcohol use to his employer and then stress the importance of weighing the potential harm of violating patient-physician confidentiality against the severity of risk to the general public.

    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

    Introduction Unhealthy alcohol use predisposes to multiple conditions that frequently result in critical illness and is present in up to one-third of patients admitted to a medical intensive care unit (ICU). We sought to determine the baseline readiness to change in medical ICU patients with unhealthy alcohol use and hypothesized that the severity of acute illness would be independently associated with higher scores on readiness to change scales. We further sought to determine whether this effect is modified by the severity of unhealthy alcohol use. Materials and Methods We performed a cross-sectional observational study of current regular drinkers in three medical ICUs. The Alcohol Use Disorders Identification Test was used to differentiate low risk and unhealthy alcohol use and further categorize patients into risky alcohol use or an alcohol use disorder. The severity of a patient’s acute illness was assessed by calculating the Acute Physiology and Chronic Healthy Evaluation II score at the time of admission to the medical ICU. Readiness to change was assessed using standardized questionnaires. Results Of 101 medical ICU patients who were enrolled, 65 met the criteria for unhealthy alcohol use. The association between the severity of acute illness and readiness to change depended on the instrument used. A higher severity of illness measured by APACHEII score was an independent predictor of readiness to change as assessed by the Stages of Change Readiness and Treatment Eagerness Scale (Taking Action scale) (p< 0.01). When a visual analog scale was used to assess readiness to change, there was a significant association with severity of acute illness (p < 0.01) that was modified by the severity of unhealthy alcohol use (p = 0.04 for interaction term). Conclusion Medical ICU patients represent a population where brief interventions require further study. Studies of brief intervention should account for the severity of acute illness and the severity of unhealthy

    People who suffer from severe mental illness often present with histories of abuse during childhood. Alcohol use disorders is a common co-morbidity of survivors of childhood abuse and neglect. This study analyzes the effects of stressful childhood experiences, a proxy for trauma, on the frequency of alcohol consumption and the utilization of health care services in a population of people with severe mental illness. There were 111 men (mean age: 35 years) and 72 women (mean age: 40.0 years) with severe mental illness that were recruited from psychiatric outpatient clinics in New York City. The analysis focused on lifetime prevalence of stressful childhood experiences, alcohol consumption, and utilization of health care services over time. The longitudinal data were analyzed over 12 months with a level-2 model (multilevel modeling). Out of the participants, 41.5% reported a history of more than four types of abusive experiences. There were 33.3% that had a DSM-IV diagnosis of alcohol abuse and 27.3% qualified for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of alcohol dependence throughout their lives. Stressful childhood experiences predicted an increased frequency of alcohol consumption over time. People with histories of childhood abuse had more often been to outpatient clinics and 12-step programs, but at the same time showed lower frequency rates of psychiatrist visits and visits to outpatient clinics. Childhood abuse is prevalent in people with severe mental illness and is related to an increased alcohol consumption. Despite an increased need of health care services, affected persons might encounter more barriers to access them.

    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.

    The purpose of this study was to explore the concepts and processes for successful abstinence from alcohol for Taiwanese Alcoholics Anonymous members. Attempting to identify the psychological and social influences upon alcohol consumption remission outside of alcoholism treatment could help professionals to engage in a broad array of community interventions in an informed fashion. Grounded theory method was utilized in this study. The study chose nine participants who had succeeded in abstinence, using theoretical sampling and conducted in-depth interviews by an open-ended questionnaire. The results of this study indicated that the core of the process during which alcoholic individuals succeeded in abstaining from further alcohol consumption was an empowerment process for the involved individual. Alcoholics felt that their family, interpersonal relationships, jobs and personal finances all had been at 'rock-bottom' level following a long period of alcohol dependence. This feeling caused the individual to experience an emotion of a loss of control and provoked the arousal of an alcoholic's inner consciousness levels, this then resulting in the generation of a driving force for abstinence from alcohol for these individuals. The expansion of an individual's internal awakening power helps the individual to obtain assistance and to resist the temptation of further alcohol consumption. Therefore, the power derived by individuals from the stages of repositioning, releasing, active sharing, resistance and assistance are the maintenance factors for an individual's empowerment process that help maintain the successful recovery from alcohol for the involved individual. A good comprehension of the recovery processes for alcoholics, we believe, will trigger clinical professionals to pay appropriate attention to the specific problems and needs of alcoholic individuals, to build an effective resource network for treatment and to help solve alcoholics' physical and psychosocial

    Although marijuana dependence is prevalent, most individuals with marijuana dependence do not seek treatment. There are few data characterizing treatment seeking marijuana-dependent patients compared to patients presenting for treatment of other drugs regarding the severity of illness and motivation for treatment. Forty-two marijuana-dependent individuals were compared to 58 cocaine-dependent individuals seeking treatment. Compared to cocaine-dependent patients, those with marijuana dependence were younger and less likely to be dependent on alcohol or other drugs. Both groups had similar rates of comorbid anxiety and affective disorders. Marijuana-dependent individuals had lower total number of dependence symptoms but had a higher percentage of individuals endorsing withdrawal symptoms. Although marijuana-dependent individuals had less outpatient treatment exposure, the difference between the two groups was not significant and motivation for change, based on the University of Rhode Island Change Assessment, was similar for both groups of treatment seekers. However, the Circumstances, Motivation, Readiness for Treatment Scale suggested that cocaine-dependent individuals were more motivated for treatment. Taken together, these data suggest that treatment seeking marijuana-dependent individuals have substantial withdrawal dependence symptomatology although it is less clear if they are as motivated to seek out treatment as cocaine-dependent treatment seekers.

    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

    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.

    Most young adult women who smoke marijuana also drink alcohol. Marijuana-related problems are associated with marijuana use frequency. We hypothesized that increased alcohol use frequency potentiates the association between frequency of marijuana use and marijuana-related problem severity. We recruited women aged 18 to 24 who smoked marijuana at least monthly and were not treatment seeking. Marijuana and alcohol use were measured using the timeline follow-back method. Problems associated with marijuana use were assessed using the Marijuana Problems Scale. Participants (n = 332) averaged 20.5 ± 1.8 years of age, were 66.7% non-Hispanic White, and reported using marijuana on 51.5 ± 30.6 and alcohol on 18.9 ± 16.8 of the 90 previous days. Controlling for education, ethnicity, years of marijuana use, and other drug use, frequency of marijuana use (b = .22; p < .01) and frequency of alcohol use (b = 0.13; p < .05) had significant, positive effects on marijuana problem severity. In a separate multivariate model, the linear by linear interaction of marijuana by alcohol use frequency was significant (b = 0.18; p < .01), consistent with the hypothesis. Concurrent alcohol use impacts the experience of negative consequences from marijuana use in a community sample of young women. Discussions of marijuana use in young adults should consider the possible potentiating effects of alcohol use. Copyright © 2014 Jacobs Institute of Women's Health. Published by Elsevier Inc.

    People with substance dependence have health consequences, high health care utilization, and frequent comorbidity but often receive poor-quality care. Chronic care management (CCM) has been proposed as an approach to improve care and outcomes. To determine whether CCM for alcohol and other drug dependence improves substance use outcomes compared with usual primary care. The AHEAD study, a randomized trial conducted among 563 people with alcohol and other drug dependence at a Boston, Massachusetts, hospital-based primary care practice. Participants were recruited from September 2006 to September 2008 from a freestanding residential detoxification unit and referrals from an urban teaching hospital and advertisements; 95% completed 12-month follow-up. Participants were randomized to receive CCM (n=282) or no CCM (n=281). Chronic care management included longitudinal care coordinated with a primary care clinician; motivational enhancement therapy; relapse prevention counseling; and on-site medical, addiction, and psychiatric treatment, social work assistance, and referrals (including mutual help). The no CCM (control) group received a primary care appointment and a list of treatment resources including a telephone number to arrange counseling. The primary outcome was self-reported abstinence from opioids, stimulants, or heavy drinking. Biomarkers were secondary outcomes. There was no significant difference in abstinence from opioids, stimulants, or heavy drinking between the CCM (44%) and control (42%) groups (adjusted odds ratio, 0.84; 95% CI, 0.65-1.10; P=.21). No significant differences were found for secondary outcomes of addiction severity, health-related quality of life, or drug problems. No subgroup effects were found except among those with alcohol dependence, in whom CCM was associated with fewer alcohol problems (mean score, 10 vs 13; incidence rate ratio, 0.85; 95% CI, 0.72-1.00; P=.048). Among persons with alcohol and other drug dependence, CCM compared

    It is well known that Complementary Medicine (CM) is extensively used in western countries for the treatment of many afflictions. CM has been recently promoted in addiction treatment. To evaluate CM use in alcohol dependence we planned a mail questionnaire for Italian alcohol services. We sent out 612 questionnaires. Health services that were unable to respond to the questionnaire within a 20-day limit period were contacted by phone and if we obtained agreement to participate in the study the questionnaire was sent by fax. We obtained 312 (51.82%) completed questionnaires. Only 16.50% of Italian services use CM for alcohol dependence treatment and acupuncture is utilized more frequently than other methods (phytotherapy, homeopathy, etc.). In Italian alcohol services CM is identified as an instrument incorporated into traditional alcohol treatments (self-help groups, drug treatment, etc.) and not an alternative method. In fact, health services that use it as a principal method of treatment were a rare event in our study (1%). CM plays an integrated role with traditional forms of alcohol treatment in Italian alcohol services and this utilization could be useful to reduce drop-outs and improve alcohol treatment compliance.

    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.

    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.

    To compare the efficacy of acamprosate and naltrexone in the treatment of alcohol dependence. A double-blind, placebo-controlled trial. Three treatment centres in Australia. A total of 169 alcohol dependent subjects were given naltrexone (50 mg/day), acamprosate (1998 mg/day) or placebo for 12 weeks. All subjects were offered manualized compliance therapy, a brief intervention that targets problems that may affect treatment compliance such as ambivalence and misperceptions about medication. Time to the first drink, time to first relapse, drinks per drinking day and cumulative abstinence. In intention-to-treat analyses, there were no differences between groups on outcome measures of drinking, craving or biochemical markers. Similarly, analyses of the 94 subjects that completed the study in full and demonstrated 80% compliance, revealed no significant treatment effects. Differential treatment effects were identified after stratification according to scores on the Alcohol Dependence Scale (ADS) and Depression Anxiety and Stress Scale (DASS). A significant beneficial treatment effect on time to first relapse was revealed for subjects with 'no depression' allocated to naltrexone (n = 56; P < 0.01). In addition, a significant beneficial treatment effect was revealed in subjects with 'low dependence' allocated to naltrexone (n = 34; P < 0.05). The results of this study support the efficacy of naltrexone in the relapse prevention of alcoholism amongst those with low levels of clinical depression and alcohol dependence severity. No effect of acamprosate was found in our sample.

    A major hypothesis in addiction research is that alcohol induces neuroadaptations in the mesolimbic dopamine (DA) system and that these neuroadaptations represent a key neurochemical event in compulsive drug use and relapse. Whether these neuroadaptations lead to a hypo- or hyperdopaminergic state during abstinence is a long-standing, unresolved debate among addiction researchers. The answer is of critical importance for understanding the neurobiological mechanism of addictive behavior. Here we set out to study systematically the neuroadaptive changes in the DA system during the addiction cycle in alcohol-dependent patients and rats. In postmortem brain samples from human alcoholics we found a strong down-regulation of the D1 receptor- and DA transporter (DAT)-binding sites, but D2-like receptor binding was unaffected. To gain insight into the time course of these neuroadaptations, we compared the human data with that from alcohol-dependent rats at several time points during abstinence. We found a dynamic regulation of D1 and DAT during 3 wk of abstinence. After the third week the rat data mirrored our human data. This time point was characterized by elevated extracellular DA levels, lack of synaptic response to D1 stimulation, and augmented motor activity. Further functional evidence is given by a genetic rat model for hyperdopaminergia that resembles a phenocopy of alcohol-dependent rats during protracted abstinence. In summary, we provide a new dynamic model of abstinence-related changes in the striatal DA system; in this model a hyperdopaminergic state during protracted abstinence is associated with vulnerability for relapse.

    Alcohol dependence is a devastating illness affecting a large population, and new pharmacological treatments with good efficacy are greatly needed. One potential candidate is varenicline, a smoking cessation agent with partial agonist action at α4 β2 nicotinic acetylcholine receptors. A total of 160 subjects, 30 to 70 years of age, fulfilling DSM-IV criteria for alcohol dependence without any serious physical or mental disorders, were recruited through advertisement at 3 university clinics in Sweden during March 2009 to January 2011. After a 2-week placebo run-in period, subjects received 2 mg varenicline daily (titrated from 0.5 mg during first week) or placebo for 12 weeks in a double-blind manner. The primary outcome was the proportion of heavy drinking days, measured by self-reported alcohol consumption. Primary and secondary outcomes were calculated as a mean over the 10-week steady-state active treatment period. In the primary outcome analysis, no effect of varenicline over placebo was found (p = 0.73 for the intention to treat [ITT] and 0.92 for per protocol [PP]). Secondary outcome analysis found a significant reduction of specific alcohol marker phosphatidylethanol (PEth) in the blood in the varenicline group compared to placebo (p = 0.02 ITT). Craving (p = 0.048 PP) and Alcohol Use Disorders Identification Test (AUDIT) scores (p = 0.015 ITT) were also reduced in the active treatment group. PEth more strongly correlated with self-reported alcohol consumption than carbohydrate-deficient ttransferrin and γ-glutamyl transferase, and correlation coefficients were higher in the varenicline group than in the placebo group for all markers. Although the results of the main outcome of this study did not support an effect of varenicline in alcohol-dependent individuals, the secondary analyses of PEth, craving and AUDIT score support an effect of varenicline on alcohol consumption.

    Individuals with alcohol use disorders have been shown to be at increased risk for suicidal behaviors and chronic pain. The aim of this study was to conduct initial analyses of the association between current physical pain and the likelihood of suicidal behavior history in alcohol-dependent patients entering treatment in Poland. A sample of 366 (73.5% men and 26.5% women) participants were recruited from alcohol treatment centers in Warsaw, Poland. Information was obtained about a history of lifetime suicidal behavior, past 4-week pain level, demographics, social functioning, childhood abuse, depressive symptoms, severity of alcohol and sleep problems. A total of 118 individuals (32.2%) reported at least one suicidal behavior during their lifetime. In unadjusted analyses, there was a significant association between a history of lifetime suicidal behavior and a moderate or greater experience of physical pain during the last four weeks. Other variables that were significantly associated with suicidal behaviors were: younger age, history of childhood abuse, depressive symptoms, sleep problems, consequences of drinking, and lower social support. In the multivariate logistic regression analysis, only experience of moderate or greater pain, age, and depressive symptoms remained significantly associated with a history of suicidal behavior. The experience of physical pain is significantly associated with a lifetime history of suicidal behavior in alcohol-dependent patients. Clinicians should be aware of these associations when conducting assessments and treating alcohol use disorders.

    Alcohol-related motor vehicle collisions are a major cause of mortality in trauma patients. This prospective observational study investigated the influence of antecedent alcohol use on outcomes in trauma patients who survived to reach the hospital. From 2005 to 2011, all patients who were older than 18 years and were admitted as a result of motor vehicle crashes were included. Blood alcohol concentration (BAC) was routinely measured for each patient on admission. Patients were divided into four groups based on their BAC level, which included nondrinking, BAC less than 100, BAC 100 to 200, and BAC 200 mg/dL or greater. Patient demographics, physical status and injury severity on admission, length of hospital stay, and outcome were compared between the groups. Odds ratios of having a severe injury, prolonged hospital stay, and mortality were estimated. Patients with a positive BAC had an increased risk of sustaining craniofacial and thoracoabdominal injuries. Odds ratios of having severe injuries (Injury Severity Score [ISS] 16 or greater) and a prolonged hospital stay were also increased. However, for those patients whose ISS was 16 or greater and who also had a brain injury, risk of fatality was significantly reduced if they were intoxicated (BAC 200 mg/dL or greater) before injury. Alcohol consumption does not protect patients from sustaining severe injuries nor does it shorten the length of hospital stay. However, there were potential survival benefits related to alcohol consumption for patients with brain injuries but not for those without brain injuries. Additional research is required to investigate the mechanism of this association further.

    Conventional meta-analysis based on genetic markers may be less powerful for heterogeneous samples. In this study, we introduced a new meta-analysis for 4 genomewide association studies on alcohol dependence that integrated the information of putative causal variants. A total of 12,481 subjects in 4 independent cohorts were analyzed, including 1 European American cohort (1,409 cases with alcohol dependence and 1,518 controls), 1 European Australian cohort (a total of 6,438 family subjects with 1,645 probands), 1 African American cohort from SAGE + COGA (681 cases and 508 controls), and 1 African American cohort from Yale (1,429 cases and 498 controls). The genomewide association analysis was conducted for each cohort, and then, a new meta-analysis was performed to derive the combined p-values. cis-Acting expression of quantitative locus (cis-eQTL) analysis of each risk variant in human tissues and RNA expression analysis of each risk gene in rat brain served as functional validation. In meta-analysis of European American and European Australian cohorts, we found 10 top-ranked single nucleotide polymorphisms (SNPs) (p < 10(-6) ) that were associated with alcohol dependence. They included 6 at SERINC2 (3.1 × 10(-8) ≤ p ≤ 9.6 × 10(-8) ), 1 at STK40 (p = 1.3 × 10(-7) ), 2 at KIAA0040 (3.3 × 10(-7) ≤ p ≤ 5.2 × 10(-7) ), and 1 at IPO11 (p = 6.9 × 10(-7) ). In meta-analysis of 2 African American cohorts, we found 2 top-ranked SNPs including 1 at SLC6A11 (p = 2.7 × 10(-7) ) and 1 at CBLN2 (p = 7.4 × 10(-7) ). In meta-analysis of all 4 cohorts, we found 2 top-ranked SNPs in PTP4A1-PHF3 locus (6.0 × 10(-7) ≤ p ≤ 7.2 × 10(-7) ). In an African American cohort only, we found 1 top-ranked SNP at PLD1 (p = 8.3 × 10(-7) ; OR = 1.56). Many risk SNPs had positive cis-eQTL signals, and all these risk genes except KIAA0040 were found to express in both rat and mouse brains. We found multiple genes that were significantly or suggestively associated with alcohol

    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

    Neurocognitive deficits in chronic alcoholic men are well documented. Impairments include memory, visual-spatial processing, problem solving and executive function. The cause of impairment could include direct effects of alcohol toxicity, pre-existing cognitive deficits that predispose towards substance abuse, comorbid psychiatric disorders and abuse of substances other than alcohol. Cigarette smoking occurs at higher rates in alcoholism and has been linked to poor cognitive performance, yet the effects of smoking on cognitive function in alcoholism are often ignored. We examined whether chronic alcoholism and chronic smoking have effects on executive function. Alcoholism and smoking were examined in a community-recruited sample of alcoholic and non-alcoholic men (n = 240) using standard neuropsychological and reaction-time measures of executive function. Alcoholism was measured as the average level of alcoholism diagnoses across the study duration (12 years). Smoking was measured in pack-years. Both alcoholism and smoking were correlated negatively with a composite executive function score. For component measures, alcoholism was correlated negatively with a broad range of measures, whereas smoking was correlated negatively with measures that emphasize response speed. In regression analyses, both smoking and alcoholism were significant predictors of executive function composite. However, when IQ is included in the regression analyses, alcoholism severity is no longer significant. Both smoking and alcoholism were related to executive function. However, the effect of alcoholism was not independent of IQ, suggesting a generalized effect, perhaps affecting a wide range of cognitive abilities of which executive function is a component. On the other hand, the effect of smoking on measures relying on response speed were independent of IQ, suggesting a more specific processing speed deficit associated with chronic smoking.

    While not well known in the West, Taiwan has a substantial indigenous population, and this population has rapidly developed alcohol problems. This study examined the level of insight into alcohol-related problems and its associations with the severity of alcohol consumption, mental health status, race, and the level of acculturation among indigenous populations with alcohol problems in southern Taiwan. A total of 332 indigenes, whose total Alcohol Use Disorders Identification Test (AUDIT) score was equal to 8 or higher, were interviewed. The associations between the level of insight into alcohol-related problems and the severity of alcohol drinking on the AUDIT, mental health status on the Chinese Health Questionnaire-12 (>or= 4 vs. < 4), race (Bunun vs. non-Bunun), and the level of acculturation on the Taiwan Aboriginal Acculturation Scale were examined using logistic regression models. The results of this study found that 72.6% of the participants had poor insight into alcohol-related problems and no participant had good insight. Participants who had more severe alcohol drinking or poor mental health were more likely to have a higher level of insight into alcohol-related problems. Participants who were non-Bunun were also more likely to have a higher level of insight into alcohol-related problems, but the level of acculturation was not associated with the level of insight into alcohol-related problems. These findings suggest that most alcoholic indigenes in southern Taiwan have poor insight into their own alcohol-related problems. Cultural specific interventions targeting and improving the indigenes' insight into alcohol-related problems are needed.

    To investigate the underlying neurobiology between alcohol use, misuse and dependence and cognitive impairment, particularly Alzheimer's disease (AD). Review of the literature using searches of Medline, Pubmed, EMBASE, PsycInfo, and meeting abstracts and presentations. The role of alcohol as a risk factor and contributor for cognitive decline associated with AD has received little attention. This is despite the high prevalence of alcohol use, the potential reversibility of a degree of cognitive impairment and the global burden of AD. Until now the focus has largely been on the toxic effects of alcohol, neuronal loss and the role of thiamine. We propose alcohol adds to the cognitive burden seen in dementia through additional mechanisms to neurodegenerative processes or may contribute at various mechanistic points in the genesis and sustenance of AD pathology via neuroinflammation. We describe the common underlying neurobiology in alcohol and AD, and examine ways alcohol likely contributes to neuroinflammation directly via stimulation of Toll-like receptors and indirectly from small bowel changes, hepatic changes, withdrawal and traumatic brain injury to the pathogenesis of AD. Alcohol use, misuse and dependence cause cognitive impairment. We propose alcohol adds to the cognitive burden seen in dementia through additional mechanisms to neurodegenerative processes or may contribute at various mechanistic points in the genesis and sustenance of AD pathology via neuroinflammation. © The Author 2016.

    An effort has been mounted to understand the mechanisms of alcohol dependence in a way that may allow for greater efficacy in treatment. It has long been suggested that drugs of abuse seize fundamental reward pathways and disrupt homeostasis to produce compulsive drug seeking behaviors. Ghrelin, an endogenous hormone that affects hunger state and release of growth hormone, has been shown to increased alcohol intake following administration, while antagonists decrease intake. Using rodent models of dependence, the current study examined the effects of two ghrelin receptor antagonists, [DLys3]-GHRP-6 (DLys) and JMV2959, on dependence-induced alcohol self-administration. In two experiments adult male C57BL/6J mice and Wistar rats were made dependent via intermittent ethanol vapor exposure. In another experiment, adult male C57BL/6J mice were made dependent using the intragastric alcohol consumption (IGAC) procedure. Ghrelin receptor antagonists were given prior to voluntary ethanol drinking. Ghrelin antagonists reduced ethanol intake, preference, and operant self-administration of ethanol and sucrose across these models, but did not decrease food consumption in mice. In experiments 1 and 2, voluntary drinking was reduced by ghrelin receptor antagonists, however this reduction did not persist across days. Despite the transient effects to ghrelin antagonists, the drugs had renewed effectiveness following a break in administration as seen in experiment 1. The results show the ghrelin system as a potential target for studies of alcohol abuse. Further research is needed to determine the central mechanisms of these drugs and their influence on addiction in order to design effective pharmacotherapies. PMID:26051399

    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

    Substance use and smoking co-occur at high rates and substance abusers smoke more and have greater difficulty quitting smoking compared to the general population. Methods of increasing smoking cessation among alcoholics are needed to improve their health. This study investigated predictors of motivation to quit smoking among patients early in residential treatment for substance abuse. The 198 alcohol dependent patients were participating is a larger smoking study at an inner-city residential substance abuse treatment program. Motivation was measured by the Contemplation Ladder. A hierarchical multiple regression was conducted to assess whether perceived barriers to smoking cessation and self-efficacy about quitting were associated with motivation to quit smoking independent of the influence of degree of tobacco involvement, substance use, and comorbid depressive symptoms. Motivation was higher with longer previous smoking abstinence, fewer barriers to quitting, and greater self-efficacy but was not influenced by smoking rate, dependence, or gender. While the combination of alcohol and drug use, alcohol and drug problem severity, and depressive symptoms predicted motivation, no one of these variables was significant. Since barriers to change and self-efficacy are potentially modifiable in treatment, these could be salient targets for intervention efforts. This could be integrated into treatment by assessing barriers and providing corrective information about consequences and methods of overcoming barriers and by providing coping skills to increase confidence in one’s ability to quit smoking.

    This randomized, double-blind, placebo-controlled study compared the effects of high-dose (100 mg/d) naltrexone versus placebo in a sample of 87 randomized subjects with both cocaine and alcohol dependence. Medication conditions were crossed with two behavioral therapy platforms that examined whether adding contingency management (CM) that targeted cocaine abstinence would enhance naltrexone effects compared to cognitive behavioral therapy (CBT) without CM. Primary outcome measures for cocaine (urine screens) and alcohol use (timeline followback) were collected thrice-weekly during 12 weeks of treatment. Retention in treatment and medication compliance rates were low. Rates of cocaine use and drinks per day did not differ between treatment groups; however naltrexone did reduce frequency of heavy drinking days, as did CBT without CM. Notably, adding CM to CBT did not enhance treatment outcomes. These weak findings suggest that pharmacological and behavioral interventions that have shown efficacy in the treatment of a single drug dependence disorder may not provide the coverage needed when targeting dual drug dependence.

We used the Total Army Injury and Health Outcomes Database (TAIHOD) to conduct cross-sectional analyses of the association between alcohol comorbidity and the cause, type and severity of soldiers' non-combat injuries requiring hospitalization. Subjects were active-duty US army soldiers (n = 211 790) hospitalized with a primary diagnosis of injury between 1980 and 2002. Alcohol comorbidity was positively associated with hospitalized injuries resulting from fights and falls and negatively associated with sports injuries; positively associated with hospitalized cases of head injury, open wounds and poisonings and negatively associated with musculoskeletal injury; and, overall, associated with shorter length of stay. Controlling for demographic factors did not moderate the association between alcohol and cause, type or severity of injury. Alcohol comorbidity is specifically associated with injuries related to impairment and antisocial behavior.

    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.

    The balance between inhibitory (gamma aminobutyric acid; GABAergic) and excitatory (glutamatergic) neurotransmission is thought to be associated with craving for alcohol and food. The anticraving effect of acamprosate is thought to be mediated through modifying the balance of GABA and glutamate. Recent studies in animals have suggested that acamprosate may have non-selective effects on craving for both alcohol and food. The influence of acamprosate for reducing craving for alcohol and food was assessed in 204 in-patients with alcohol dependence (96 patients treated with acamprosate, PWA; 108 patients were not treated PNA) was assessed at baseline and following 1, 2, and 4 weeks of treatment. There was a significant reduction in craving for alcohol over 4 weeks of treatment in both PWA and PNA groups, but without significant group differences. In contrast, a reduction in food craving was observed only in the PWA group. In addition, there was a significant increase of body mass index (BMI) in the PNA group but not the PWA group over the 4-week period. These results demonstrate acamprosate nonselective effects on craving for drinking and eating in alcoholic patients.

    This study examined (a) the direct association of family cohesion on alcohol use severity among adult Hispanic immigrants; (b) the indirect association of family cohesion on alcohol use severity via social support; and (c) if gender moderates the direct and indirect associations between family cohesion and alcohol use severity. Mediation and moderation analyses were conducted on a cross-sectional sample of 411 (men = 222, women = 189) participants from Miami-Dade, Florida. Findings indicate that higher family cohesion was directly associated with higher social support and lower alcohol use severity. Higher social support was also directly associated with lower alcohol use severity. Additionally, family cohesion had an indirect association with alcohol use severity via social support. Moderation analyses indicated that gender moderated the direct association between family cohesion and alcohol use severity, but did not moderate the indirect association. Some potential clinical implications may be that strengthening family cohesion may enhance levels of social support, and in turn, lower alcohol use severity among adult Hispanic immigrants. Furthermore, strengthening family cohesion may be especially beneficial to men in efforts to lower levels of alcohol use severity.

    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

    Ethanol is a renewable biofuel, and it can be produced from lignocellulosic biomass. The biomass is usually converted to hydrolysates that consist of sugar and sugar derivatives, such as furfural. Yeast ferments sugar to ethanol, but furfural higher than 3 mM is inhibitory. It can take several days for yeast cells to reduce furfural to non-inhibitory furfuryl alcohol before producing ethanol. Bioreduction of furfural to furfuryl alcohol before fermentation may relieve yeast from furfural toxicity. We observed that Cupriavidus necator JMP134, a strict aerobe, rapidly reduced 17 mM furfural to less than 3 mM within 14 min with cell turbidity of 1.0 at 600 nm at 50°C. The rapid reduction consumed ethanol. The "furfural reductase" (FurX) was purified, and it oxidized ethanol to acetaldehyde and reduced furfural to furfuryl alcohol with NAD(+) as the cofactor. The protein was identified with mass spectrometry fingerprinting to be a hypothetical protein belonging to Zn-dependent alcohol dehydrogenase family. The furX-inactivation mutant of C. necator JMP134 lost the ability to rapidly reduce furfural, and Escherichia coli producing recombinant FurX gained the ability. Thus, an alcohol dehydrogenase enabled bacteria to rapidly reduce furfural with ethanol as the reducing power.

    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.

    The aim of this exploratory archival study was to discern the utility of the Iowa Gambling Task (IGT) in identifying adaptive decision-making capacities among pilots with a history of alcohol dependence both with and without Cluster B personality features. Participants included 18 male airmen at the rank of captain with a history of receiving alcohol dependence treatment and subsequent referral for a fitness-for-duty evaluation. Data from prior comprehensive neuropsychological evaluations conducted in a private practice setting at the mandate of the FAA utilizing criteria outlined in the HIMS program was used. ANOVA was conducted to compare pilots with (N = 4) and without Cluster B personality features (N = 14) on measures of decisionmaking capacities, intelligence, and executive functioning. Pilots with Cluster B personality features were found to have a significantly lower Total Net T-Score on IGT (M = 35.00, SD = 9.27) than pilots without features of Cluster B (M = 56.36, SD = 9.55). Furthermore, with the exception of the first 20 cards (i.e., Net 1); the groups significantly differed in their Net scores. No statistically significant difference was found on airmen's intelligence and executive functioning. The present study found that alcohol-dependent airmen with Cluster B personality features evidenced significantly poorer decisionmaking capacities as measured by the ICT in comparison to alcohol dependent airman without Cluster B personality features. Implications and limitations of the study are discussed.

Among alternative therapies, the therapeutic potential of the non-competitive N-methyl-D-aspartate receptor antagonist memantine has been suggested. Despite promising results, its efficiency in the treatment of alcoholism remains controversial. Currently, there is no pre-clinical data regarding its effects on the motivation for ethanol in post-dependent (PD) animals exposed to intermittent ethanol vapor, a validated model of alcoholism. Thus, the objectives of this study were to evaluate the effects of acute injections of memantine (0, 12.5, 25 and 50 mg/kg) on operant ethanol self-administration in non-dependent (ND) and PD rats tested either during acute withdrawal or relapse after protracted abstinence. Our results showed that memantine (25 mg/kg) abolished ethanol self-administration in ND rats and reduced by half the one of PD rats during acute withdrawal. While this effect was observed only 6 hours after treatment in ND rats, it was long lasting in PD rats (at least 30 hours after injection). Furthermore, our results indicated that memantine did not modify the breaking point for ethanol. This suggests that memantine probably act by potentiating the pharmacological effect of ethanol but not by reducing motivation for ethanol. Finally, memantine was also ineffective in reducing relapse after protracted abstinence. Altogether, our pre-clinical results highlighted a potential therapeutic use of memantine that may be used as a replacement therapy drug but not as relapse-preventing drug. © 2014 Society for the Study of Addiction.

    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.

    Background In alcohol dependence, markers of inflammation are associated with increases in rapid eye movement (REM) sleep, which is thought to be a prognostic indicator of alcohol relapse. This study was undertaken to test whether blockade of biologically active tumor necrosis factor-α (TNF-α) normalizes REM sleep in alcohol-dependent adults. Methods In a randomized, placebo-controlled, double-blind, crossover trial, 18 abstinent alcohol-dependent male adults received a single dose of etanercept (25 mg) versus placebo in a counterbalanced order. Polysomnographic sleep was measured at baseline and for 3 nights after the acute dose of etanercept or placebo. Results Compared with placebo, administration of etanercept produced significant decreases in the amount and percentage of REM sleep. Decreases in REM sleep were robust and approached low levels typically found in age-comparable control subjects. Individual differences in biologically active drug as indexed by circulating levels of soluble tumor necrosis factor receptor II negatively correlated with the percentage of REM sleep. Conclusions Pharmacologic neutralization of TNF-α activity is associated with significant reductions in REM sleep in abstinent alcohol-dependent patients. These data suggest that circulating levels of TNF-α may have a physiologic role in the regulation of REM sleep in humans. PMID:19185287

    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.

  1. Episodic Future Thinking: Expansion of the Temporal Window in Individuals with Alcohol Dependence.

    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.

    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.

    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.

    Interventions targeting physical activity may be valuable as an adjunct to alcohol treatment, but have been relative untested. In the current study, alcohol dependent, physically sedentary patients were randomized to: a 12-week moderate-intensity, group aerobic exercise intervention (AE; n = 25) or a brief advice to exercise intervention (BA-E; n=23). Results showed that individuals in AE reported significantly fewer drinking and heavy drinking days, relative to BA-E during treatment. Furthermore adherence to AE strengthened the beneficial effect of intervention on alcohol use outcomes. While high levels of moderate-intensity exercise appeared to facilitate alcohol recovery regardless of intervention arm, attending the group-based AE intervention seemed to further enhance the positive effects of exercise on alcohol use. Study findings indicate that a moderate intensity, group aerobic exercise intervention is an efficacious adjunct to alcohol treatment. Improving adherence to the intervention may enhance its beneficial effects on alcohol use. PMID:24666811

    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

    Many real-world eyewitnesses are under the influence of alcohol either at the time of the crime, the interview, or both. Only recently has empirical research begun to examine the effects of alcohol on witness memory, yielding mixed results. The present study tested the importance of state-dependent memory in the context of alcohol's effects on encoding versus retrieval of a witnessed event, while simultaneously informing real-world investigative practices: Should witnesses sober up before an interview? Participants (N = 249) were randomized to a control, placebo, or alcohol condition at encoding and to either an immediate retrieval condition (in the same state) or a 1-week delay control, placebo, or alcohol retrieval condition. They recalled a witnessed mock crime using open ended and cued recall formats. After a delay, witnesses intoxicated at both encoding and retrieval provided less accurate information than witnesses in sober or placebo groups at both times. There was no advantage of state-dependent memory but intoxicated witnesses were best when recalling immediately compared to 1 week later (sober, placebo, or reintoxicated). Findings have direct implications for the timing of intoxicated witnesses' interviews such that moderately intoxicated witnesses may not benefit from a sobering delay but rather, should be interviewed immediately.

  10. Biochemical characterization of ethanol-dependent reduction of furfural by alcohol dehydrogenases.

    PubMed

    Lignocellulosic biomass is usually converted to hydrolysates, which consist of sugars and sugar derivatives, such as furfural. Before yeast ferments sugars to ethanol, it reduces toxic furfural to non-inhibitory furfuryl alcohol in a prolonged lag phase. Bioreduction of furfural may shorten the lag phase. Cupriavidus necator JMP134 rapidly reduces furfural with a Zn-dependent alcohol dehydrogenase (FurX) at the expense of ethanol (Li et al. 2011). The mechanism of the ethanol-dependent reduction of furfural by FurX and three homologous alcohol dehydrogenases was investigated. The reduction consisted of two individual reactions: ethanol-dependent reduction of NAD(+) to NADH and then NADH-dependent reduction of furfural to furfuryl alcohol. The kinetic parameters of the coupled reaction and the individual reactions were determined for the four enzymes. The data indicated that limited NADH was released in the coupled reaction. The enzymes had high affinities for NADH (e.g., K ( d ) of 0.043 μM for the FurX-NADH complex) and relatively low affinities for NAD(+) (e.g., K ( d ) of 87 μM for FurX-NAD(+)). The kinetic data suggest that the four enzymes are efficient "furfural reductases" with either ethanol or NADH as the reducing power. The standard free energy change (ΔG°') for ethanol-dependent reduction of furfural was determined to be -1.1 kJ mol(-1). The physiological benefit for ethanol-dependent reduction of furfural is likely to replace toxic and recalcitrant furfural with less toxic and more biodegradable acetaldehyde.

    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.

    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.

    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.

    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.

    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.

    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.

    Recombinant pyridine nucleotide transhydrogenase (PNT) from Escherichia coli has been used to regenerate NAD+ and NADPH. The pnta and pntb genes encoding for the alpha- and beta-subunits were cloned and co-expressed with NADP+-dependent alcohol dehydrogenase (ADH) from Lactobacillus kefir and NAD+-dependent formate dehydrogenase (FDH) from Candida boidinii. Using this whole-cell biocatalyst, efficient conversion of prochiral ketones to chiral alcohols was achieved: 66% acetophenone was reduced to (R)-phenylethanol over 12 h, whereas only 19% (R)-phenylethanol was formed under the same conditions with cells containing ADH and FDH genes but without PNT genes. Cells that were permeabilized with toluene showed ketone reduction only if both cofactors were present.

    The aim of this study was to determine the association between alcohol dependence and altitude of residence in 11 villages in two high altitude areas of Peru. An analytical cross-sectional study was performed using a survey conducted by physicians in primary health care in 11 villages until 2013, that were divided into low altitude (≤2500m asl (above sea level)), and high altitude (>2500m asl) areas. The CAGE test for alcoholism (cut point, ≥2) was applied to those who responded positively when asked if they consumed alcohol. Statistical associations were obtained with generalised linear models Of the 737 participants, 51% were women and the median age was 36 years [interquartile range, 25-50], 334 (45%) lived at low altitude, and 113 (15%) had alcohol dependence. The highest frequency of alcoholism was positively associated with being a village considered extremely poor (Likelihood Ratio (LP)=2.42; 95%CI, 1.40-4.19), while being female (LP=0.44; 95%CI, 0.23-0.89) and residing at high altitude (LP=0.15; 95%CI, 0.07-0.31) were negatively associated. These were adjusted for nine socio-occupational and pathological variables. According to these data, there is a higher frequency of alcohol dependence in being, male, extremely poor, and residing at low altitude. These results should be taken into account by professionals who work in primary care and those involved in mental health care, because of their implications in society.

    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

    Emotion regulation difficulties are a potentially key mechanism underlying the association between childhood maltreatment and alcohol use in adulthood. The current study examined the mediating role of emotion regulation difficulties in the association between childhood maltreatment severity (i.e., Childhood Trauma Questionnaire total score) and past-month alcohol use severity, including alcohol consumption frequency and alcohol-related problems (i.e., number of days of alcohol problems, ratings of "bother" caused by alcohol problems, ratings of treatment importance for alcohol problems). Participants included 111 acute-care psychiatric inpatients (45.0% female; Mage=33.5, SD=10.6), who reported at least one DSM-5 posttraumatic stress disorder Criterion A traumatic event, indexed via the Life Events Checklist for DSM-5. Participants completed questionnaires regarding childhood maltreatment, emotion regulation difficulties, and alcohol use. A significant indirect effect of childhood maltreatment severity via emotion regulation difficulties in relation to alcohol use severity (β=0.07, SE=0.04, 99% CI [0.01, 0.21]) was documented. Specifically, significant indirect effects were found for childhood maltreatment severity via emotion regulation difficulties in relation to alcohol problems (β's between 0.05 and 0.12; all 99% bootstrapped CIs with 10,000 resamples did not include 0) but not alcohol consumption. Emotion regulation difficulties may play a significant role in the association between childhood maltreatment severity and alcohol outcomes. Clinical implications are discussed.

    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.

    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.

    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

    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.

    Naltrexone has been identified as a promising psychopharmacological treatment for alcohol dependence. Previous studies have suggested that its efficacy may vary based on ethnic background. The current study examined the efficacy of naltrexone in the treatment of alcohol dependence in Latino adults, a previously unexplored population. This was a secondary analysis of the Combined Pharmacotherapies and Behavioral Interventions for Alcohol Dependence (COMBINE) Study. The overall COMBINE sample consisted of 1,383 adult participants who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for alcohol dependence, including 155 Latinos, who are the focus of this report. Consistent with the main trial, primary drinking outcomes, including percentage of days abstinent (PDA) and time to first heavy drinking day (TTHD), were examined. In addition, we examined the effects of naltrexone on a clinically relevant secondary outcome measure, global clinical outcome of alcohol consumption and alcohol-related problems. As seen with the subsample of African Americans from the COMBINE Study, results of the present analysis indicated that there were no significant effects of naltrexone on PDA and TTHD despite these significant effects in the original study. However, contrary to findings in the African American subsample, for Latino participants naltrexone was a significant predictor of a good global clinical outcome (i.e., abstinence or moderate drinking without problems). Naltrexone was not significantly associated with improvements in the primary drinking outcomes of PDA or TTHD at the end of treatment or at follow-up. However, Latinos appeared to benefit from naltrexone as demonstrated by improved ratings of global clinical outcome. These results indicate mixed findings for the efficacy of naltrexone among Latinos in the COMBINE Study.

    Growing evidence suggests that the consumption of caffeinated alcoholic beverages (CAB) may be riskier than alcohol alone. Efforts to identify patterns of CAB use and the correlates of such drinking patterns could further our conceptualization of and intervention for this health issue. Consequently, the current study aimed to (1) identify distinct classes of CAB users, (2) examine differences between classes on measures of alcohol and caffeine problems, and (3) compare distinct classes of CAB users on caffeine and alcohol outcome expectancies. Participants were 583 (31% men) undergraduate students from a psychology research pool. Latent profile analysis models were derived using four indicators: CAB use quantity, CAB use frequency, alcohol use quantity, and alcohol use frequency. Finding revealed four classes of drinkers: High Alcohol/High CAB (6.00%), High Alcohol/Moderate CAB (5.15%), High Alcohol/Low CAB (22.99%), and Low Alcohol/Low CAB (65.87%). The Low Alcohol/Low CAB class reported the lowest relative levels of caffeine dependence symptoms, caffeine withdrawal, alcohol use problems, and heavy episodic drinking frequency. Further, results indicated differential expectancy endorsement based on use profiles. CAB users in the High Alcohol/Low CAB class endorsed more positive alcohol expectancies than the Low Alcohol/Low CAB group. Those in the High Alcohol/High CAB class endorsed stronger withdrawal symptoms caffeine expectancies than all other classes. Inclusion of substance-specific expectancies into larger theoretical frameworks in future work of CAB use may be beneficial. Findings may inform intervention efforts for those at greatest risk related to CAB consumption. PMID:24210683

A combination of random probability and simple quota sampling to conduct monthly cross-sectional household computer-assisted interviews between March 2014 and August 2017. The general population in all nine regions of England. Participants in the Alcohol Toolkit Study (ATS), a monthly household survey of alcohol consumption among people aged 16 years and over in England (n = 69 826). The mean age was 47 years [standard deviation (SD) = 18.78; 95% confidence interval (CI) = 46.8-47] and 51% (n = 35 560) were female. χ 2 tests were used to investigate associations with demographic variables, motivation to quit drinking, attempts to quit drinking, general practitioner (GP) engagement and types of support accessed in the last 12 months across AUDIT risk zones. A total of 0.6% were classified as people with probable alcohol dependence (95% CI = 0.5-0.7). Motivation to quit (χ 2  = 1692.27, P < 0.001), current attempts (χ 2  = 473.94, P < 0.001) and past-year attempts (χ 2  = 593.67, P < 0.001) differed by AUDIT risk zone. People with probable dependence were more likely than other ATS participants to have a past-year attempt to cut down or quit (51.8%) and have received a specialist referral from their GP about drinking (13.7%), and less likely to report no motivation to reduce their drinking (26.2%). Those with probable dependence had higher use of self-help books and mobile applications (apps) than other ATS participants; however, 27.7% did not access any resources during their most recent attempt to cut down. Adults in England with probable alcohol dependence, measured through the Alcohol Use Disorders Identification Test, demonstrate higher

    In recent years, some new processes have been proposed to explain how alcohol may influence behavior, psychological symptoms and alcohol seeking in alcohol-dependent subjects. In addition to its important effect on brain and neurotransmitters equilibrium, alcohol abuse also affects peripheral organs including the gut. By yet incompletely understood mechanisms, chronic alcohol abuse increases intestinal permeability and alters the composition of the gut microbiota, allowing bacterial components from the gut lumen to reach the systemic circulation. These gut-derived bacterial products are recognized by immune cells circulating in the blood or residing in target organs, which consequently synthesize and release pro-inflammatory cytokines. Circulating cytokines are considered important mediators of the gut–brain communication, as they can reach the central nervous system and induce neuroinflammation that is associated with change in mood, cognition and drinking behavior. These observations support the possibility that targeting the gut microbiota, by the use of probiotics or prebiotics, could restore the gut barrier function, reduce systemic inflammation and may have beneficial effect in treating alcohol dependence and in reducing alcohol relapse.

    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.

    Scientific literature suggests a large number of symptoms that may be present the day after excessive alcohol consumption. The purpose of this study was to explore the presence and severity of hangover symptoms, and determine their interrelationship. A survey was conducted among n = 1410 Dutch students examining their drinking behavior and latest alcohol hangover. The severity of 47 presumed hangover symptoms were scored on a 10-point scale ranging from 0 (absent) to 10 (maximal). Factor analysis was conducted to summarize the data into groups of associated symptoms that contribute significantly to the alcohol hangover and symptoms that do not. About half of the participants (56.1%, n = 791) reported having had a hangover during the past month. Most commonly reported and most severe hangover symptoms were fatigue (95.5%) and thirst (89.1%). Factor analysis revealed 11 factors that together account for 62% of variance. The most prominent factor 'drowsiness' (explained variance 28.8%) included symptoms such as drowsiness, fatigue, sleepiness and weakness. The second factor 'cognitive problems' (explained variance 5.9%) included symptoms such as reduced alertness, memory and concentration problems. Other factors, including the factor 'disturbed water balance' comprising frequently reported symptoms such as 'dry mouth' and 'thirst', contributed much less to the overall hangover (explained variance <5%). Drowsiness and impaired cognitive functioning are the two dominant features of alcohol hangover.

    Although the precise drug mechanism of action of acamprosate remains unclear, its antidipsotropic effect is mediated in part through glutamatergic neurotransmission. We evaluated the effect of 4 weeks of acamprosate treatment in a cohort of 13 subjects with alcohol dependence (confirmed by a structured interview, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) on proton magnetic resonance spectroscopy glutamate levels in the midline anterior cingulate cortex (MACC). We compared levels of metabolites with a group of 16 healthy controls. The Pennsylvania Alcohol Craving Scale was used to assess craving intensity. At baseline, before treatment, the mean cerebrospinal fluid-corrected MACC glutamate (Glu) level was significantly elevated in subjects with alcohol dependence compared with controls (P = 0.004). Four weeks of acamprosate treatment reduced glutamate levels (P = 0.025), an effect that was not observed in subjects who did not take acamprosate. At baseline, there was a significant positive correlation between cravings, measured by the Pennsylvania Alcohol Craving Scale, and MACC (Glu) levels (P = 0.019). Overall, these data would suggest a normalizing effect of acamprosate on a hyperglutamatergic state observed in recently withdrawn patients with alcohol dependence and a positive association between MACC glutamate levels and craving intensity in early abstinence. Further research is needed to evaluate the use of these findings for clinical practice, including monitoring of craving intensity and individualized selection of treatment with antidipsotropic medications in subjects with alcohol dependence.

    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.

    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

    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.

    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.

    The aim of this study was to investigate the effects of t'ai chi on blood serotonin levels, nicotine dependence, depression, and anger in hospitalized alcohol-dependent patients. This study followed an experimental and nonequivalent control group in a non-synchronized design. It was performed in a hospital located in Young Ju city, Korea, from April to August 2013. Thirty-eight patients who were hospitalized with alcohol dependence were included. They were randomly divided into an experimental and a control group, with 19 patients in each group. Patients in the experimental group practiced the 24-posture yang style t'ai chi for 50 min three times per week for 8 weeks as part of the routine hospital rehabilitation program, and those in the control group followed only the routine hospital rehabilitation program. The effect of treatment was measured using blood serotonin levels and a questionnaire on nicotine dependence, depression, and anger. Both measurements were performed before and after 8 weeks of intervention. Data were analyzed using the t-test, chi-square test, and paired t-tests. The experimental group showed a significantly increased blood serotonin level (p = 0.001) and significantly reduced nicotine dependence, depression, and anger (p = 0.001) than the control group did after 8 weeks of treatment. T'ai chi was shown to be an effective nursing intervention in hospitalized alcohol-dependent patients.

    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

    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. 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. 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). 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.

    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

    Proposed International Classification of Diseases, 11th edition (ICD-11), criteria for substance use disorder (SUD) radically simplify the algorithm used to diagnose substance dependence. Major differences in case identification across DSM and ICD impact determinations of treatment need and conceptualizations of substance dependence. This study compared the draft algorithm for ICD-11 SUD against DSM-IV, DSM-5, and ICD-10, for alcohol and cannabis. Adolescents (n = 339, ages 14 to 18) admitted to intensive outpatient addictions treatment completed, as part of a research study, a Structured Clinical Interview for DSM SUDs adapted for use with adolescents and which has been used to assess DSM and ICD SUD diagnoses. Analyses examined prevalence across classification systems, diagnostic concordance, and sources of diagnostic disagreement. Prevalence of any past-year proposed ICD-11 alcohol or cannabis use disorder was significantly lower compared to DSM-IV and DSM-5 (ps < 0.01). However, prevalence of proposed ICD-11 alcohol and cannabis dependence diagnoses was significantly higher compared to DSM-IV, DSM-5, and ICD-10 (ps < 0.01). ICD-11 and DSM-5 SUD diagnoses showed only moderate concordance. For both alcohol and cannabis, youth typically met criteria for an ICD-11 dependence diagnosis by reporting tolerance and much time spent using or recovering from the substance, rather than symptoms indicating impaired control over use. The proposed ICD-11 dependence algorithm appears to "overdiagnose" dependence on alcohol and cannabis relative to DSM-IV and ICD-10 dependence, and DSM-5 moderate/severe use disorder, generating potential "false-positive" cases of dependence. Among youth who met criteria for proposed ICD-11 dependence, few reported impaired control over substance use, highlighting ongoing issues in the conceptualization and diagnosis of SUD.

    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

    Alcohol-induced intestinal dysbiosis is central to the development of the severe alcoholic liver disease. We present the first study to compare outcomes in patients of severe alcoholic hepatitis (SAH) on nutritional therapy, corticosteroids, pentoxifylline, and healthy donor fecal transplantation (FMT) and discuss distinct microbial community and microbiome metabolic functional changes after FMT. Out of 1271 liver disease patients, 809 (63.7%) were diagnosed to have the alcoholic liver disease, of which 51 patients (8 treated with corticosteroids, 17 with nutritional support only, 10 with pentoxifylline, 16 receiving FMT) were included. Clinical, biochemical parameters, liver disease, and alcoholic hepatitis severity scores at baseline and mortality at the end of 1 and 3 months were analyzed between groups. Stool microbiota (SM) analysis was performed for healthy controls (HC) and respective recipients after FMT. All the patients were male. The proportions of patients surviving at the end of 1 and 3 months in the steroids, nutrition, pentoxifylline, and FMT group were 63%, 47%, 40% and 75% [p = 0.179] and 38%, 29%, 30%, and 75% [p = 0.036], respectively. When compared with FMT, relative risk and hazard ratios for death were higher in all the other groups. Following FMT, distinct and beneficial modulation of SM and pathways of dysregulated metabolism, infections, inflammation, and oxidative stress in SAH patients were noted in tandem with improved clinical outcomes. Healthy donor FMT for SAH improves survival beyond what is offered by current therapies and can function as a cost-effective bridge to liver transplant (LT) or for improving transplant-free survival. Larger studies and randomized trials are unmet needs.

    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.

    The authors make an introduction where they describe several problems found in the alcoholic diseases researches. The most important of them are related to the "alcoholic case" concept. After this the authors report several epidemiological facts about the alcoholic diseases and disorders in Castilla-León and Madrid. Then a retrospective analysis of inpatients psychiatric records from the Psychiatry Department of Valladolid's University Hospital between 1980 to 1984 (N = 1.259) is made. 252 (20.01%) of them suffered an alcoholic disorders, following the I.C.D.-9th criteria psychoses alcoholic were 102 (8.10%) and they were excluded. However "Alcohol dependence" with 128 cases (10.17%) and "Alcohol Abuse Syndromes" with 22 cases (1.75%) were studied deeply, being 150 cases--120 males (80%) and 30 females (20%)--evaluated. Every diagnostic group was analysed in a distinct way through 41 epidemiological, clinical, diagnostic and medical care variables. These two groups and their differences and similarities between them are reported. The main profile is a male patient, 43 years old, married, urban life, blue collar worker, unskilled work, primary studies, bad economic level, marriage and working maladapted, clinical admitted through the Emergency Service, with an alcoholism 24 years old and intake of 234 grs. alcohol/day, with former treatment of minor tranquilizers (B.D.Z.) and at last is readmitted by alcoholic disease of disorder or a different psychiatric disease or disorders (I.C.D.-9.a or D.S.M.-III) in a 37.5% and 16.41% respectively.

    Blockade of the μ-opioid receptor (MOR) by naltrexone reduces relapse risk in a subpopulation of alcohol-dependent patients. Previous positron-emission-tomography (PET) studies using the MOR ligand [11C]carfentanil have found increased MOR availability in abstinent alcoholics, which may reflect either increased MOR expression or lower endogenous ligand concentration. To differentiate between both effects, we investigated two cohorts of alcoholic subjects using either post-mortem or clinical PET analysis. Post-mortem brain tissue of alcohol-dependent subjects and controls (N=43/group) was quantitatively analyzed for MOR ([3H]DAMGO)-binding sites and OPRM1 mRNA in striatal regions. [11C]carfentanil PET was performed in detoxified, medication free alcohol-dependent patients (N=38), followed by a randomized controlled study of naltrexone versus placebo and follow-up for 1 year (clinical trial number: NCT00317031). Because the functional OPRM1 variant rs1799971:A>G affects the ligand binding, allele carrier status was considered in the analyses. MOR-binding sites were reduced by 23–51% in post-mortem striatal tissue of alcoholics. In the PET study, a significant interaction of OPRM1 genotype, binding potential (BPND) for [11C]carfentanil in the ventral striatum, and relapse risk was found. Particularly in G-allele carriers, lower striatal BPND was associated with a higher relapse risk. Interestingly, this effect was more pronounced in the naltrexone treatment group. Reduced MOR is interpreted as a neuroadaptation to an alcohol-induced release of endogenous ligands in patients with severe alcoholism. Low MOR availability may explain the ineffectiveness of naltrexone treatment in this subpopulation. Finally, low MOR-binding sites are proposed as a molecular marker for a negative disease course.

    With the increasing legalization of cannabis, understanding the consequences of cannabis use is particularly timely. We examined the association between cannabis use and dependence, prospectively assessed between ages 18–38, and economic and social problems at age 38. We studied participants in the Dunedin Longitudinal Study, a cohort (n=1,037) followed from birth to age 38. Study members with regular cannabis use and persistent dependence experienced downward socioeconomic mobility, more financial difficulties, workplace problems, and relationship conflict in early midlife. Cannabis dependence was not linked to traffic-related convictions. Associations were not explained by socioeconomic adversity, childhood psychopathology, achievement orientation, or family structure; cannabis-related criminal convictions; early onset of cannabis dependence; or comorbid substance dependence. Cannabis dependence was associated with more financial difficulties than alcohol dependence; no difference was found in risks for other economic or social problems. Cannabis dependence is not associated with fewer harmful economic and social problems than alcohol dependence. PMID:28008372

    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

    Several lines of evidence suggest that fluctuations in endogenous levels of the γ-aminobutyric acid (GABA)ergic neurosteroid allopregnanolone (ALLO) represent one mechanism for regulation of GABAergic inhibitory tone in the brain, with an ultimate impact on behavior. Consistent with this idea, there was an inverse relationship between ALLO levels and symptoms of anxiety and depression in humans and convulsive activity in rodents during alcohol withdrawal. Our recent studies examined the activity and expression of 5α-reductase (Srd5a1), the rate-limiting enzyme in the biosynthesis of ALLO, during alcohol withdrawal in mice selectively bred for high chronic alcohol withdrawal (Withdrawal Seizure-Prone [WSP]) and found that Srd5a1 was downregulated in the cortex and hippocampus over the time course of dependence and withdrawal. The purpose of the present studies was to extend these findings and more discretely map the regions of Srd5a1 expression in mouse brain using radioactive in situ hybridization in WSP mice that were ethanol naïve, following exposure to 72h ethanol vapor (dependent) or during peak withdrawal. In naïve animals, expression of Srd5a1 was widely distributed throughout the mouse brain, with highest expression in specific regions of the cerebral cortex, hippocampus, thalamus, hypothalamus, and amygdala. In dependent animals and during withdrawal, there was no change in Srd5a1 expression in cortex or hippocampus, which differed from our recent findings in dissected tissues. These results suggest that local Srd5a1 mRNA expression in WSP brain may not change in parallel with local ALLO content or withdrawal severity. Published by Elsevier Inc.

    Despite real-world implications, the pattern of delay discounting in alcohol users when the commodities now and later differ has not been well characterized. In this study, 60 participants on Amazon's Mechanical Turk completed the Alcohol Use Disorder Identification Test (AUDIT) to assess severity of use and completed four delay discounting tasks between hypothetical, equivalent amounts of alcohol and money available at five delays. The tasks included two cross-commodity (alcohol now-money later and money now-alcohol later) and two same-commodity (money now-money later and alcohol now-alcohol later) conditions. Delay discounting was significantly associated with clinical cutoffs of the AUDIT for both of the cross-commodity conditions but not for either of the same-commodity delay discounting tasks. The cross-commodity discounting conditions were related to severity of use wherein heavy users discounted future alcohol less and future money more. The change in direction of the discounting effect was dependent on the commodity that was distally available suggesting a distinctive pattern of discounting across commodities when comparing light and heavy alcohol users.

    Chronic alcohol abuse is characterized by impaired cognitive abilities with a more severe deficit in visual than in verbal functions. Neuropathologically, it is associated with widespread brain structural compromise marked by gray matter shrinkage, ventricular enlargement, and white matter degradation. The present study sought to increase current understanding of the impairment of visual processing abilities in alcohol-dependent subjects, and its correlation with white matter microstructural alterations, using diffusion tensor imaging (DTI). To that end, a DTI study was carried out on 35 alcohol-dependent subjects and 30 healthy male control subjects. Neuropsychological tests were assessed for visual processing skills and deficits were reported as raw dysfunction scores (rDyS). Reduced FA (fractional anisotropy) and increased MD (mean diffusivity) were observed bilaterally in inferior and superior fronto-occipital fasciculus (FOF) fiber bundles. A significant inverse correlation in rDyS and FA values was observed in these fiber tracts whereas a positive correlation of these scores was found with the MD values. Our results suggest that FOF fiber bundles linking the frontal lobe to occipital lobe might be related to visual processing skills. This is the first report of an alteration of the white matter microstructure of FOF fiber bundles that might have functional consequences for visual processing in alcohol-dependent subjects who exhibit no neurological complications.

    Substance dependence is characterized by compulsive drug-taking despite negative consequences. Animal research suggests an underlying imbalance between goal-directed and habitual action control with chronic drug use. However, this imbalance, and its associated neurophysiological mechanisms, has not yet been experimentally investigated in human drug abusers. The aim of the present study therefore was to assess the balance between goal-directed and habit-based learning and its neural correlates in abstinent alcohol-dependent (AD) patients. A total of 31 AD patients and 19 age, gender and education matched healthy controls (HC) underwent functional magnetic resonance imaging (fMRI) during completion of an instrumental learning task designed to study the balance between goal-directed and habit learning. Task performance and task-related blood oxygen level-dependent activations in the brain were compared between AD patients and healthy matched controls. Findings were additionally associated with duration and severity of alcohol dependence. The results of this study provide evidence for an overreliance on stimulus-response habit learning in AD compared with HC, which was accompanied by decreased engagement of brain areas implicated in goal-directed action (ventromedial prefrontal cortex and anterior putamen) and increased recruitment of brain areas implicated in habit learning (posterior putamen) in AD patients. In conclusion, this is the first human study to provide experimental evidence for a disturbed balance between goal-directed and habitual control by use of an instrumental learning task, and to directly implicate cortical dysfunction to overreliance on inflexible habits in AD patients.

Secondary analysis of the database of the first Mental Health Population Survey conducted in the city of Medellin in 2011 and 2012 based on the methodology of the World Mental Health Survey guidelines and coordinated by WHO-HARVARD. The lifetime prevalence of abuse and dependence in people with social phobia was 24.1% and 11.2%, respectively. For people with social phobia the prevalence was 13% for abuse and 4.4% for dependence (OR=2.11 for abuse, OR=2.46 for dependence). Annual prevalence of people with social phobia who abused or were dependent on alcohol was 7.8% and 5.9%, respectively, compared to those who do not suffer from this disorder, with a prevalence of 3.4% and 1.7%, respectively (OR=2.39 for abuse and OR=3.57 for dependence). There was significant correlation in the annual and lifetime prevalence between social phobia and the pathological consumption of alcohol. Statistically significant relationships were found for the variables associated with social phobia, however, more work is needed to confirm or refute these associations.

    Introduction Little is known about how alcohol treatment rates vary across age or years since onset of an alcohol use disorder (AUD). We examined past-year treatment prevalence and associations across these important time metrics. Method Data on 22,278 adults ages 18–50 were from the National Epidemiologic Survey on Alcohol and Related Conditions-III (2012–2013). We examined the age-varying prevalence of alcohol treatment and associations of past-year AUD severity, MDD status, and DUD status with treatment. Additionally, for individuals with a lifetime AUD (N=7,089), we examined associations of severity, MDD, and DUD across years since AUD onset. Results Individuals with Moderate/Severe past-year AUD had significantly higher treatment rates at nearly all ages, compared to those with Mild or no AUD. For those with Moderate/Severe AUD, treatment rates were highest during late adolescence and middle adulthood and lowest during early adulthood. Mental health comorbidities were positively associated with treatment at certain age ranges in mid-adulthood. Among individuals with a lifetime AUD, those with Moderate/Severe past-year AUD had significantly higher past-year treatment rates across all years since onset. MDD and DUD were both positively associated with treatment at nearly all years since AUD onset. Conclusions Alcohol treatment rates varied notably by age and, to a lesser extent, by years since AUD onset. Greater AUD severity was consistently associated with higher rates of treatment, whereas Mild AUD had a much weaker relationship. MDD and DUD showed similar patterns of positive association with treatment. Our results highlight important subgroups where unmet treatment needs are highest. PMID:27475284

    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.

    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.

    Background Alcohol-dependent (ALC) subjects exhibit glial and neuronal pathology in the prefrontal cortex (PFC). However, in many patients, neurophysiological disturbances are not associated with catastrophic cell depletion despite prolonged alcohol abuse. It is still unclear how some relevant markers of a cell’s propensity to degenerate or proliferate are changed in the PFC of ALC subjects without major neurological disorders. Methods Levels of pro-apoptotic caspase 8 (C8), X-linked inhibitor of apoptosis protein (XIAP), direct IAP binding protein with low pI (DIABLO), proliferating cell nuclear antigen (PCNA), and density of cells immunoreactive (-IR) for proliferation marker Ki-67 were measured postmortem in the left orbitofrontal cortex (OFC) of 29 subjects with alcohol dependence and 23 non-psychiatric comparison subjects. Results ALC subjects had significantly higher levels of the 14kDa C8 fragment (C8-14), an indicator of C8 activation. However, there was no change in the levels of DIABLO, XIAP or in the DIABLO/XIAP ratio. PCNA protein level and density of Ki-67-IR cells were not significantly changed in alcoholics, although PCNA levels were increased in older ALC subjects as compared to controls. Conclusions Significant increase of a C8 activation indicator was found in alcoholism, but without significant changes in XIAP level, DIABLO/XIAP ratio, or Ki-67 labeling. These results would help to explain the absence of catastrophic cell loss in the PFC of many alcohol dependent subjects, while still being consistent with an alcoholism-related vulnerability to slow decline in glial cells and neurons in the OFC of alcoholics.

    Alcohol and nicotine are among the top causes of preventable death in the United States. Unfortunately, people who are dependent on alcohol are more likely to smoke than individuals in the general population. Similarly, smokers are more likely to abuse alcohol. Alcohol and nicotine codependence affects health in many ways and leads to poorer treatment outcomes in subjects who want to quit. This study examined the interaction of alcohol and nicotine during withdrawal and compared abstinence symptoms during withdrawal from one of the two drugs only vs both. Our results indicate that simultaneous withdrawal from alcohol and nicotine produces physical symptoms that are more severe and last longer than those experienced during withdrawal from one of the two drugs alone. In animals experiencing withdrawal after chronic ethanol treatment, acute nicotine exposure was sufficient to prevent abstinence symptoms. Similarly, symptoms were prevented when alcohol was injected acutely in mice undergoing nicotine withdrawal. These experiments provide evidence for the involvement of the nicotinic cholinergic system in alcohol withdrawal. Furthermore, the outcomes of intracranial microinfusions of mecamylamine, a nonselective nicotinic receptor antagonist, highlight a major role for the nicotinic receptors expressed in medial habenula and interpeduncular nucleus during withdrawal. Overall, the data support the notion that modulating the nicotinic cholinergic system might help to maintain long-term abstinence from alcohol.

    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.

    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.

    Alcohol use and misuse is known to involve structural brain changes. Numerous imaging studies have examined changes in gray matter (GM) volumes in dependent drinkers, but there is little information on whether non-dependent drinking is associated with structural changes and whether these changes are related to psychological factors – such as alcohol expectancy – that influence drinking behavior. We used voxel based morphometry (VBM) to examine whether the global positive scale of alcohol expectancy, as measured by the Alcohol Expectancy Questionnaire AEQ-3, is associated with specific structural markers and whether such markers are associated with drinking behavior in 113 adult non-dependent drinkers (66 women). Alcohol expectancy is positively correlated with GM volume of left precentrral gyrus (PCG) in men and women combined and bilateral superior frontal gyri (SFG) in women, and negatively correlated with GM volume of the right ventral putamen in men. Furthermore, mediation analyses showed that the GM volume of PCG mediate the correlation of alcohol expectancy and the average number of drinks consumed per occasion and monthly total number of drinks in the past year. When recent drinking was directly accounted for in multiple regressions, GM volume of bilateral dorsolateral prefrontal cortices (DLPFC) correlated positively with alcohol expectancy in the combined sample. To our knowledge, these results are the first to identify the structural brain correlates of alcohol expectancy and its mediation of drinking behaviors. These findings suggest that more studies are needed to investigate increased GM volume in the frontal cortices as a neural correlate of alcohol expectancy. PMID:23461484

  9. Impulsivity in Alcohol-Dependent Patients with and without ADHD: The Role of Atomoxetine.

    Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of hyperactivity, inattention, and impulsivity. As shown in the literature, this disorder is frequently associated with alcohol and drug abuse. Patients affected by ADHD show high levels of impulsivity and sensation seeking. These characteristics can significantly increase the risk of alcohol abuse, which is itself a clinical condition associated with high levels of impulsivity. Clinical studies suggest that atomoxetine is effective and safe in patients affected by both ADHD and alcohol dependence; however, information focused specifically on impulsivity is very limited. In an open-label study, we evaluated the difference in impulsivity level between alcohol-dependent patients with and without a diagnosis of ADHD. Furthermore, we hypothesized that, in patients with ADHD, atomoxetine could reduce the impulsivity trait.

    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.

  11. Review of adjunctive dexmedetomidine in the management of severe acute alcohol withdrawal syndrome.

    The primary management of alcohol withdrawal involves the administration of a γ-aminobutyric acid agonist, such as benzodiazepines, for management of symptoms and to prevent further progression to seizure or delirium tremens. Despite escalating doses of benzodiazepines, published literature indicates that some patient's alcohol withdrawal syndrome symptoms do not respond, and that the use of adjunctive agents may be beneficial in these patients. Dexmedetomidine, an α2-agonist, serves as a potential adjunctive agent through management of associated autonomic symptoms. Understanding of recent literature evaluating its use is necessary for appropriate selection. To review available literature supporting the use of adjunctive dexmedetomidine for management of severe alcohol withdrawal syndrome. A total of 13 published articles evaluating the efficacy and safety of dexmedetomidine as an adjunctive agent for the treatment of alcohol withdrawal in adult patients were identified from a MEDLINE search using the key words alcohol withdrawal, delirium tremens and dexmedetomidine. Evaluation of the literature indicates that dexmedetomidine is associated with a decrease in short-term benzodiazepine requirements after initiation, and improvement in hemodynamic parameters in relation to the adrenergic drive present in alcohol withdrawal. The use of dexmedetomidine in the management of severe alcohol withdrawal should be considered as an adjunctive agent. Dexmedetomidine appears to be well tolerated, with an expected decrease in blood pressure and heart rate. Seizures have occurred in patients with alcohol withdrawal despite the use of dexmedetomidine, with and without benzodiazepines, due to lack of γ-aminobutyric acid agonist administration.

    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.

    Quality of life must be one of the main purposes for the treatment of drug users, requiring a better understanding of the association between the quality of life and the severity of dependency. This study aimed to investigate the correlation between severity of substance use in various areas of human functioning and quality of life of illicit drug users in a psychosocial care center for alcohol and drugs. This cross-sectional study included 60 participants - illicit drug users - treated at a psychosocial care center for alcohol and drugs. Participants were evaluated with the short version of World Health Organization Quality of Life (WHOQOL-Bref) instrument to measure the quality of life, the 6th version of Addiction Severity Index (ASI-6) to assess the severity of dependence in several areas and the Mini International Neuropsychiatric Interview (MINI) to identify the presence of psychiatric disorders. Pearson and Spearman correlation tests and linear regression were applied to verify the association between the severity of dependence and the quality of life, and Student's t-test to compare the mean quality of life between individuals with and without psychiatric comorbidities. Negative correlation was found between the severity of dependence on the drugs dimensions: alcohol, psychiatric, medical, legal, family/social support and family/social problems of ASI-6, and the quality of life domains measured by the WHOQOL-Bref. The evidence was strongest in the psychiatric and medical dimensions. There was a significant difference in the quality of life mean among participants presenting or not presenting psychiatric comorbidities, for the psychological domain in anxiety disorders, and for the physical and psychological domains in mood disorders. The quality of life decreased as the severity of dependence increased, with different results in the various areas of the participant's life. This result emphasizes the need for training the professional team which works in the

    Aim: To conduct a double-blind, placebo-controlled randomized clinical trial of baclofen in the treatment of alcohol dependence. Methods: Out of 69 participants consecutively screened, 42 alcohol-dependent patients were randomized to receive placebo, baclofen 30 mg/day or baclofen 60 mg/day for 12 weeks. All subjects were offered BRENDA, a structured psychosocial therapy for alcohol dependence that seeks to improve motivation for change, enhance strategies to prevent relapse and encourage compliance with treatment. Results: Intention-to-treat analyses revealed that alcohol consumption (heavy drinking days, drinks per drinking day) significantly reduced across all three groups during the treatment period. There were no statistically significant advantages to treatment on time to first heavy drinking day (relapse) (P = 0.08), nor time to first drink (lapse) (P = 0.18). A post hoc analysis stratifying according to whether there had been a comorbid anxiety disorder, revealed a beneficial effect of baclofen 30 mg/day versus placebo on time to lapse and relapse (P < 0.05). There was also a beneficial effect for baclofen 60 mg/day relative to placebo on time to relapse in this comorbid group (P < 0.05). Both doses of baclofen were well tolerated. There were no serious adverse events. Conclusions: In spite of the small sample for a 3-arm clinical trial, this study suggests a specific role of baclofen in alcohol-dependent individuals with comorbid anxiety. Replication in larger, fully-powered studies is required. PMID:25246489

    Personality traits have been found as strong predictors for treatment response in different psychiatric disorders. We administered the Tridimensional Personality Questionnaire, which measures the three personality dimensions: novelty seeking, harm avoidance (HA), and reward dependence, as introduced by Cloninger in a multicenter study (11 centers in the United Kingdom, Eire, Switzerland, and Austria) with detoxified alcohol-dependent patients (n = 521). The objective of this study was to evaluate a possible predictive value of these three dimensions on relapse over 1 -year follow up. A logistic regression analysis showed that novelty seeking is a strong predictor for relapse in detoxified male alcoholics (p = 0.0007; p values adjusted for treatment), but not in females. In both sexes, HA and reward dependence were of no predictive value. However, we found a trend for significance of HA for predicting "early" relapse (4 weeks) in females (p = 0.074). Our results show that Tridimensional Personality Questionnaire personality traits have direct clinical applications for prediction of relapse in detoxified alcohol dependents and indicate the necessity of additional therapeutic treatment in risk groups.

Gender, social support, and an allelic variant in the gene encoding the serotonin transporter (5-HTTLPR) were examined as moderators of this relationship. The Semi-Structured Assessment for the Genetics of Alcoholism - Version II (SSAGA-II) was used to assess DSM-IV diagnoses and cigarette smoking characteristics as well as traumatic life events and social support during childhood in 256 AD men (n=149) and women (n=107). An increase in number of adverse childhood events was associated with heightened risk of cigarette use and nicotine dependence. 5-HTTLPR genotype, gender, and social support did not significantly moderate the relationships among childhood adversity and ever-smoking or nicotine dependence. Results extend previous findings to suggest that childhood adversity is strongly related to risk for ever-smoking and nicotine dependence in AD individuals. Additional research is needed to examine other potential genetic and environmental moderators and mediators of the relationships among smoking, alcohol use, and childhood trauma.

    Abstract Background and aims Sleep disturbance is a prominent complaint in cocaine and alcohol dependence. This controlled study evaluated differences of polysomnographic (PSG) sleep in cocaine‐ and alcohol‐dependent subjects, and examined whether substance dependence interacts with age to alter slow wave sleep and rapid eye movement (REM) sleep. Design Cross‐sectional comparison. Setting Los Angeles and San Diego, CA, USA. Participants Abstinent cocaine‐dependent subjects (n = 32), abstinent alcohol‐dependent subjects (n = 73) and controls (n = 108); mean age 40.3 years recruited 2005–12. Measurements PSG measures of sleep continuity and sleep architecture primary outcomes of Stage 3 sleep and REM sleep. Covariates included age, ethnicity, education, smoking, body mass index and depressive symptoms. Findings Compared with controls, both groups of substance dependent subjects showed loss of Stage 3 sleep (P < 0.001). A substance dependence × age interaction was found in which both cocaine‐ and alcohol‐dependent groups showed loss of Stage 3 sleep at an earlier age than controls (P < 0.05 for all), and cocaine‐dependent subjects showed loss of Stage 3 sleep at an earlier age than alcoholics (P < 0.05). Compared with controls, REM sleep was increased in both substance‐dependent groups (P < 0.001), and cocaine and alcohol dependence were associated with earlier age‐related increase in REM sleep (P < 0.05 for all). Conclusions Cocaine and alcohol dependence appear to be associated with marked disturbances of sleep architecture, including increased rapid eye movement sleep and accelerated age‐related loss of slow wave, Stage 3 sleep.

    The aims of the current study were to examine the associations among behavioral economic measures of alcohol value derived from three distinct measurement approaches, and to evaluate their respective relations with traditional indicators of alcohol problem severity in college drinkers. Five behavioral economic metrics were derived from hypothetical demand curves that quantify reward value by plotting consumption and expenditures as a function of price, another metric measured proportional behavioral allocation and enjoyment related to alcohol versus other activities, and a final metric measured relative discretionary expenditures on alcohol. The sample included 207 heavy drinking college students (53% female) who were recruited through an on-campus health center or university courses. Factor analysis revealed that the alcohol valuation construct comprises two factors: one factor that reflects participants’ levels of alcohol price sensitivity (demand persistence), and a second factor that reflects participants’ maximum consumption and monetary and behavioral allocation towards alcohol (amplitude of demand). The demand persistence and behavioral allocation metrics demonstrated the strongest and most consistent multivariate relations with alcohol-related problems, even when controlling for other well-established predictors. The results suggest that behavioral economic indices of reward value show meaningful relations with alcohol problem severity in young adults. Despite the presence of some gender differences, these measures appear to be useful problem indicators for men and women. PMID:24749779

    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.

    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).

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).

    Autobiographical memory (AM) enables the storage and retrieval of life experiences that allow individuals to build their sense of identity. Several AM impairments have been described in patients with alcohol abuse disorders without assessing whether such deficits can be recovered. This cross-sectional study aimed to identify whether the semantic (SAM) and episodic (EAM) dimensions of AM are affected in individuals with alcohol dependence after short-term abstinence (STA) or long-term abstinence (LTA). A second aim of this study was to examine the factors that could disrupt the efficiency of semantic and episodic AM (the impact of depression severity, cognitive functions, recent or early traumatic events, and drinking history variables). After clinical and cognitive evaluations (alcohol consumption, depression, anxiety, IQ, memory performance), AM was assessed with the Autobiographical Memory Interview in patients with recent (between 4 and 6 weeks) and longer (at least 6 months) abstinence. Participants were asked to retrieve the number and nature of traumatic or painful life experiences in recent or early life periods (using the Childhood Traumatic Events Scale). The 2 abstinent groups had lower global EAM and SAM scores than the control group. These scores were comparable for both abstinent groups. For childhood events, no significant differences were observed in SAM for both groups compared with control participants. For early adulthood and recent events, both STA and LTA groups had lower scores on both SAM and EAM. Moreover, there was a negative correlation between the length of substance consumption and SAM scores. This study highlighted a specific AM disorder in both episodic and semantic dimensions. These deficits remained after 6 months of abstinence. This AM impairment may be explained by compromised encoding and consolidation of memories during bouts of drinking.

    The present invention relates to microorganisms and polypeptides for detoxifying aldehydes associated with industrial fermentations. In particular, a heat-stable, NADPH- and iron-dependent alcohol dehydrogenase was cloned from Thermoanaerobacter pseudethanolicus 39E and displayed activity against a number of aldehydes including inhibitory compounds that are produced during the dilute-acid pretreatment process of lignocellulosic biomass before fermentation to biofuels. Methods to use the microorganisms and polypeptides of the invention for improved conversion of bio mass to biofuel are provided as well as use of the enzyme in metabolic engineering strategies for producing longer-chain alcohols from sugars using thermophilic, fermentative microorganisms.

    Alcohol craving is a major cause of relapse in alcohol-dependent (AD) patients. It is closely related to the high depression and anxiety symptoms that are frequently observed at the early stages of abstinence, and these comorbid symptoms might thus constitute a relapse factor when they persist after detoxification. As these negative affects are known to evolve during the detoxification process, the aim of this study was to investigate the course of the relation between affects and craving during detoxification, with a particular attention given to gender in light of the known differences in affects between AD men and women. AD patients (n = 256) undergoing a detoxification program were evaluated for positive (PA) and negative affectivity (NA), depression and anxiety symptoms, and craving, twice within a 3-week interval (on the first [T1] and the eighteenth day [T2] of abstinence). Detoxification course was associated with improvements regarding NA, depression and anxiety symptoms, and craving. Moreover, these negative affects were related to craving intensity. However, for men, the relation was only present at the beginning of detoxification, while, for women, it persisted at the end of detoxification as did high levels of depression. Furthermore, only with women was the level of craving at T2 proportional to negative affects reported at T1, and depression symptoms experienced at T1 were reliable predictors of craving at T2. Given the importance of craving in relapse, special care should be given to improve depressive symptoms in AD women to promote long-term abstinence. Also, the remaining portion of AD women who still exhibit substantial symptoms of anxiety and depression at the end of detoxification could benefit from an integrated treatment simultaneously tackling mood and alcohol-dependence disorders.

    Recognizing others' emotions is a fundamental social skill, widely impaired in psychiatric populations. These emotional dysfunctions are involved in the development and maintenance of alcohol-related disorders, but their differential intensity across emotions and their modifications during disease evolution remain underexplored. Affective prosody decoding was assessed through a vocalization task using six emotions, among 17 patients with severe alcohol use disorder, 16 Korsakoff syndrome patients (diagnosed following DSM-V criteria) and 19 controls. Significant disturbances in emotional decoding, particularly for negative emotions, were found in alcohol-related disorders. These impairments, identical for both experimental groups, constitute a core deficit in excessive alcohol use. Copyright © 2018 Elsevier B.V. All rights reserved.

  10. The effects of drug and alcohol consumption on driver injury severities in single-vehicle crashes.

    It is well known that alcohol and drugs influence driving behavior by affecting the central nervous system, awareness, vision, and perception/reaction times, but the resulting effect on driver injuries in car crashes is not fully understood. The purpose of this study was to identify factors affecting the injury severities of unimpaired, alcohol-impaired, and drug-impaired drivers. The current article applies a random parameters logit model to study the differences in injury severities among unimpaired, alcohol-impaired, and drug-impaired drivers. Using data from single-vehicle crashes in Cook County, Illinois, over a 9-year period from January 1, 2004, to December 31, 2012, separate models for unimpaired, alcohol-impaired, and drug-impaired drivers were estimated. A wide range of variables potentially affecting driver injury severity was considered, including roadway and environmental conditions, driver attributes, time and location of the crash, and crash-specific factors. The estimation results show significant differences in the determinants of driver injury severities across groups of unimpaired, alcohol-impaired, and drug-impaired drivers. The findings also show that unimpaired drivers are understandably more responsive to variations in lighting, adverse weather, and road conditions, but these drivers also tend to have much more heterogeneity in their behavioral responses to these conditions, relative to impaired drivers. In addition, age and gender were found to be important determinants of injury severity, but the effects varied significantly across all drivers, particularly among alcohol-impaired drivers. The model estimation results show that statistically significant differences exist in driver injury severities among the unimpaired, alcohol-impaired, and drug-impaired driver groups considered. Specifically, we find that unimpaired drivers tend to have more heterogeneity in their injury outcomes in the presence potentially adverse weather and road surface

    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.

    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.

  13. Sweet preference, sugar addiction and the familial history of alcohol dependence: shared neural pathways and genes.

    PubMed

    Fortuna, Jeffrey L

    2010-06-01

    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.

    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

    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.

    To analyse the possible associations between sweet preference and the efficacy of naltrexone treatment of alcohol dependence. The preference for different concentrations of sucrose was evaluated in 78 participants diagnosed with alcohol dependence after treatment for 32 weeks with naltrexone or placebo without prior detoxification. A significant difference between naltrexone and placebo groups was found in the association between the preference for higher sucrose concentrations and relapses to heavy drinking. Higher sweet preference was significantly related to successful treatment measures in the naltrexone group but not in the placebo group. Sweet preference has a strong correlation to treatment outcomes with naltrexone, and sweet preference might be used as a predictor for better treatment results in alcoholics. Our study offers one possible new explanation of the clinical observation that naltrexone is not effective for every patient.

    Objectives Alcohol is responsible for a proportion of emergency admissions to hospital, with acute alcohol intoxication and chronic alcohol dependency (CAD) implicated. This study aims to quantify the proportion of hospital admissions through our emergency department (ED) which were thought by the admitting doctor to be (largely or partially) a result of alcohol consumption. Setting ED of a UK tertiary referral hospital. Participants All ED admissions occurring over 14 weeks from 1 September to 8 December 2012. Data obtained for 5497 of 5746 admissions (95.67%). Primary outcome measures Proportion of emergency admissions related to alcohol as defined by the admitting ED clinician. Secondary outcome measures Proportion of emergency admissions due to alcohol diagnosed with acute alcohol intoxication or CAD according to ICD-10 criteria. Results 1152 (21.0%, 95% CI 19.9% to 22.0%) of emergency admissions were thought to be due to alcohol. 74.6% of patients admitted due to alcohol had CAD, and significantly greater than the 26.4% with ‘Severe’ or ‘Very Severe’ acute alcohol intoxication (p<0.001). Admissions due to alcohol differed to admissions not due to alcohol being on average younger (45 vs 56 years, p<0.001) more often male (73.4% vs 45.1% males, p<0.001) and more likely to have a diagnosis synonymous with alcohol or related to recreational drug use, pancreatitis, deliberate self-harm, head injury, gastritis, suicidal ideation, upper gastrointestinal bleeds or seizures (p<0.001). An increase in admissions due to alcohol on Saturdays reflects a surge in admissions with acute alcohol intoxication above the weekly average (p=0.003). Conclusions Alcohol was thought to be implicated in 21% of emergency admissions in this cohort. CAD is responsible for a significantly greater proportion of admissions due to alcohol than acute intoxication. Interventions designed to reduce alcohol-related admissions must incorporate measures to tackle CAD. PMID:27324707

    The aim of this study was to evaluate possible interactions between childhood trauma, temperament, character, and psychopathology among alcohol-dependent men. Participants were 156 alcohol-dependent men consecutively admitted to a dependency treatment unit. The Childhood Abuse and Neglect Questionnaire, the Temperament and Character Inventory, and the Symptom Checklist-Revised were administered to all participants. Childhood abuse and neglect did not have any effect on temperament and character scores in multivariate analysis. Whereas childhood abuse had a significant main effect on all types of clinical psychopathology except depression and psychoticism scores, childhood neglect only had a significant main effect on depression scores. There was no interaction between childhood abuse and neglect on these analyses. Among alcohol-dependent men, childhood abuse and neglect contribute to general psychopathology through distinct clinical consequences, independently of temperamental and characterological features.

    Our aim was to examine lifetime criteria profiles and correlates of severity (mild, moderate, severe) of DSM-5 alcohol use disorders (AUD) in Puerto Rico. Data are from a household random sample of individuals 18 to 64 years of age in San Juan, Puerto Rico. The survey response rate was 83%. DSM-5 AUD was identified with the Spanish version of the World Health Organization's Composite International Diagnostic Interview. The analyses also identify correlates of each severity level using an ordered logistic regression model. The prevalence of lifetime DSM-5 AUD among men and women was 38 and 16%, respectively. Mild lifetime DSM-5 AUD was the most prevalent severity level among both men (18%) and women (9%). The most common criteria, independent of gender and severity level, were drinking larger quantities and for longer than planned (men range: 80 to 97%; women range: 78 to 91%) and hazardous use (men range: 56 to 91%; women range: 42 to 74%). Results from ordered logistic regression showed that the adjusted odds ratio for weekly drinking frequency, greater volume of alcohol consumed per drinking occasion, positive attitudes about drinking, drinking norms, and male gender invariantly increased risks across all DSM-5 AUD severity levels (mild, moderate, severe). Greater negative attitudes about drinking, low family cohesion, and Protestant religion were related to greater risks at higher AUD severity levels. AUD prevalence is high in San Juan, Puerto Rico.

    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.

    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

    Chronic alcohol abuse is associated with changes in stress and reward pathways that could alter vulnerability to emotional stress and alcohol craving. This study examines whether chronic alcohol abuse is associated with altered stress and alcohol craving responses. Treatment-engaged, 28-day abstinent alcohol-dependent individuals (ADs; 6F/22M), and social drinkers (SDs; 10F/18M) were exposed to a brief guided imagery of a personalized stressful, alcohol-related and neutral-relaxing situation, one imagery condition per session, presented in random order across 3 days. Alcohol craving, anxiety and emotion ratings, behavioral distress responses, heart rate, blood pressure, and salivary cortisol measures were assessed. Alcohol patients showed significantly elevated basal heart rate and salivary cortisol levels. Stress and alcohol cue exposure each produced a significantly enhanced and persistent craving state in alcohol patients that was marked by increased anxiety, negative emotion, systolic blood pressure responses, and, in the case of alcohol cue, behavioral distress responses, as compared to SDs. Blunted stress-induced cortisol responses were observed in the AD compared to the SD group. These data are the first to document that stress and cue exposure induce a persistent negative emotion-related alcohol craving state in abstinent alcoholics accompanied by dysregulated HPA and physiological arousal responses. As laboratory models of stress and negative mood-induced alcohol craving are predictive of relapse outcomes, one implication of the current data is that treatments targeting decreases in stress and alcohol cue-induced craving and regulation of stress responses could be of benefit in improving alcohol relapse outcomes.

    Alcohol use disorders are frequently associated with self-intoxication in attempted suicide. In France since 2008, the off-label use of baclofen for treatment of alcohol dependence has greatly increased, leading to temporary regulation of use of the drug. At the request of the national authorities, the French Poison Control Centers carried out a retrospective survey to give an overview of baclofen exposure in this population. A retrospective study was carried out from January 2008 to December 2013, focusing on baclofen exposures in alcohol-dependent patients managed by the nine national French Poison Control Centers. 294 observations of baclofen exposures in alcohol-dependent patients were identified in our database. Of these, 220 were suicide attempts by self-poisoning and 74 were unintentional. The mean age of patients was 41.7 years, with a sex-ratio of 1.6. Patients attempting suicide with baclofen were younger than those with unintentional exposures, and 43.6% of them were women (vs 22.9%, p < 0.01). The mean supposed ingested dose was higher (480.7 mg) in patients who attempted suicide (vs 192.5 mg, p < 0.0001). 21.8% of intentional exposures involved baclofen alone. Psychiatric comorbidity (50.4%) was more frequent in the group of self-poisoning (p < 0.001). 132 patients were coded as severely exposed (60.0%). Nine victims died, but the causal link between self-poisoning with baclofen and fatal outcome should be interpreted with particular caution. Baclofen self-poisoning by alcohol-dependent patients is a serious concern for the French health authorities. Our results are similar to those previously published, suggesting that most patients with baclofen overdose should be admitted to an intermediate or intensive care unit as the clinical course requires close monitoring. Because suicidal ideation and suicide attempts are more prevalent in people with substance use disorders than in the general population, and because of the lack of

    Substance dependence is characterized by compulsive drug-taking despite negative consequences. Animal research suggests an underlying imbalance between goal-directed and habitual action control with chronic drug use. However, this imbalance, and its associated neurophysiological mechanisms, has not yet been experimentally investigated in human drug abusers. The aim of the present study therefore was to assess the balance between goal-directed and habit-based learning and its neural correlates in abstinent alcohol-dependent (AD) patients. A total of 31 AD patients and 19 age, gender and education matched healthy controls (HC) underwent functional magnetic resonance imaging (fMRI) during completion of an instrumental learning task designed to study the balance between goal-directed and habit learning. Task performance and task-related blood oxygen level-dependent activations in the brain were compared between AD patients and healthy matched controls. Findings were additionally associated with duration and severity of alcohol dependence. The results of this study provide evidence for an overreliance on stimulus-response habit learning in AD compared with HC, which was accompanied by decreased engagement of brain areas implicated in goal-directed action (ventromedial prefrontal cortex and anterior putamen) and increased recruitment of brain areas implicated in habit learning (posterior putamen) in AD patients. In conclusion, this is the first human study to provide experimental evidence for a disturbed balance between goal-directed and habitual control by use of an instrumental learning task, and to directly implicate cortical dysfunction to overreliance on inflexible habits in AD patients.

    Adolescent alcohol drinking increases the risk for alcohol-use disorder in adulthood. Yet, the changes in adult neural function resulting from adolescent alcohol drinking remain poorly understood. We hypothesized that adolescent alcohol drinking alters basolateral amygdala (BLA) function, making alcohol drinking BLA-dependent in adulthood. Male, Long Evans rats were given voluntary, intermittent access to alcohol (20% ethanol) or a bitter, isocaloric control solution, across adolescence. Half of the rats in each group received neurotoxic BLA lesions. In adulthood, all rats were given voluntary, intermittent access to alcohol. BLA lesions reduced adult alcohol drinking in rats receiving adolescent access to alcohol, but not in rats receiving adolescent access to the control solution. The effect of the BLA lesion was most apparent in high alcohol drinking adolescent rats. The BLA is essential for fear learning and is hyper-active in anxiety disorders. The results are consistent with adolescent heavy alcohol drinking inducing BLA hyper-activity, providing a neural mechanism for comorbid alcohol use disorder and anxiety disorders. PMID:29135933

    Alcohol is a significant component of the diet with dose-dependent risks and benefits. High doses of alcohol damage the liver and early symptoms of liver disease include changes in routinely assessed liver enzymes. Less is known regarding the mechanisms responsible for the benefits of moderate alcohol consumption, including their effects on the liver. The objectives of this study were to examine alcohol’s dose-dependent effects on markers of liver function (alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), and bilirubin), as well as to compare the different methods of assessing alcohol intake using NHANES 2001–2010 adultmore » data (N =24,807). Three methods were used to estimate alcohol intake from all volunteers: 24-h recall; the National Cancer Institute (NCI) method of usual intake; and a specific alcohol intake questionnaire. Mean alcohol intake by 24-h recall, NCI method and questionnaire was 41.0 ± 0.8 g/d, 10.9 ± 0.2 g/d and 11.0 ± 0.2 g/d, respectively. Alcohol consumers had significantly lower levels of ALP and higher levels of AST, GGT and bilirubin compared to non-consumers (P < 0.01) and activities of ALT, AST, and GGT increased and of ALP decreased as alcohol intake increased, regardless of intake assessment method used. The most sensitive measure of alcohol consumption was GGT. Since alcohol had a graded linear effect on several liver enzymes, including at low and moderate doses, benefits as well as risks of alcohol intake may be related to liver function. In conclusion, since the NCI method and alcohol questionnaire yielded very similar alcohol intake estimates, this study cross-validated these methods and demonstrated the robustness of the NCI method for estimating intake of irregularly consumed foods.« less

    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.

    To measure the effect of community nurse follow-up on abstinence and retention rates in the outpatient treatment of alcohol-dependent patients treated with acamprosate. Recently detoxified alcohol-dependent patients were prescribed acamprosate for 26 weeks and randomized to either physician-only follow-up, or physician plus regular visits from a community nurse. Drinking behaviour in the next 26 weeks was assessed at monthly visits to non-blind clinicians. The cumulative abstinence duration proportion (CADP) was significantly longer in (P=0.03) the subjects who had received community nurse support (0.57) than in those who had not (0.39). This might, in part, be an artefact of the higher retention rate among those followed up by the nurse, in that, the method of calculating CADP allocates 100% days of drinking for the month before a failed attendance. Differences favouring nurse in the follow-up were seen for time to first drink, and clinical global impression. For recently detoxified alcohol-dependent patients treated with acamprosate, follow-up by a community nurse improves patient retention and probably also improves the 6-month drinking outcome.

    The aim of this study was to examine the correlations between the severity of alprazolam dependence and socio-demographic characteristics, the characteristics of alprazolam use, psychiatric comorbidity, and beliefs toward alprazolam use among long-term alprazolam users in Taiwan. A total of 148 long-term alprazolam users participated in this study. The Chinese version of the Severity of Dependence Scale was used to assess participants' severity of alprazolam dependence in the preceding month. Their socio-demographic characteristics, family function characteristics, dosage of prescribed alprazolam, duration of alprazolam use, alcohol use pattern, pain reliever and cigarette use pattern, severity of depressive symptoms, psychiatric diagnosis, and belief toward alprazolam use were investigated. The results of multiple regression analysis indicated that a longer duration of alprazolam use, severe depressive symptoms, a high level of belief in the necessity of alprazolam treatment, and a high level of concern about the potential adverse consequences of alprazolam use were significantly associated with more severe alprazolam dependence. Doctors should closely monitor the severity of alprazolam dependence among long-term users, especially patients' levels of depression, beliefs in the necessity of alprazolam treatment, and their concerns over the adverse consequences of continued treatment with alprazolam.

    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.

    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 current study had two goals. The first goal was to test the mediational role of young adult personality in the relation between parental alcoholism and young adult alcoholism. The second was to examine the associations between personality and alcohol use motives and reasons to limit drinking in order to explore possible mechanisms by which personality may influence alcohol abuse/dependence. Multilevel modeling techniques were used to analyze data obtained from a community sample of young adult children of alcoholics and demographically matched controls. Results revealed that young adult neuroticism and agreeableness each, in part, mediated the effect of parental alcoholism on young adult alcoholism. Moreover, individuals high in neuloticism reported stronger coping motives to use alcohol, individuals low in agreeableness reported stronger coping motives and weaker upbringing reasons to limit drinking, and individuals low in conscientiousness reported stronger coping and enhancement motives to use alcohol, and weaker performance reasons to limit drinking.

    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

    Background and Objectives The aim of this study was to investigate potential gender differences in situations associated with heavy alcohol drinking Methods Data from 395 alcohol dependent patients participating in the Mayo Clinic Intensive Addiction Program were evaluated. Each participant completed the Inventory of Drug Taking Situations (IDTS), Penn Alcohol Craving Scale (PACS), Patient Health Questionnaire (PHQ-9), and/ or Beck Depression Inventory (BDI). Gender differences in IDTS scores representing three domains (negative, positive, and temptation) of situations associated with heavy alcohol use were examined. Results Women with alcohol dependence report a higher frequency of heavy drinking in unpleasant emotional (IDTS negative scores mean ± SD women vs. men: 52.3 ± 22.1 vs. 43.8 ± 21.8; p = 0.0006), and as a result of temptation (IDTS temptation scores mean ± SD women vs. men: 40.4 ± 23.0 vs. 35.3 ± 20.8; p = 0.035). Upon admission, women also scored significantly higher on depressive symptoms as measured by the BDI (23.4± 11.4 vs. 18.2± 9.8, p <.001). After controlling for depressive symptom severity as a covariate, the IDTS gender differences were no longer significant. Conclusion and Scientific Significance Our results suggest that unpleasant or temptation based emotional situations are a vulnerability risk factor for heavy drinking particularly in females. This risk appears to be at least partially driven by depressive symptom burden. Future research is needed to further investigate this finding. PMID:23952888

    Background Over 50 years of evidence from research has established that the central dopaminergic reward pathway is likely involved in alcohol dependence (AD). Additional evidence supports a role for dopamine (DA) in other disinhibitory psychopathology, which is often comorbid with AD. Family and twin studies demonstrate that a common genetic component accounts for most of the genetic variance in these traits. Thus, DA-related genes represent putative candidates for the genetic risk that underlies not only AD but also behavioral disinhibition. Many linkage and association studies have examined these relationships with inconsistent results, possibly because of low power, poor marker coverage, and/or an inappropriate correction for multiple testing. Methods We conducted an association study on the products encoded by 10 DA-related genes (DRD1-D5, SLC18A2, SLC6A3, DDC, TH, COMT) using a large, ethnically homogeneous sample with severe AD (n = 545) and screened controls (n = 509). We collected genotypes from linkage disequilibrium (LD)-tagging single nucleotide polymorphisms (SNPs) and employed a gene-based method of correction. We tested for association with AD diagnosis in cases and controls and with a variety of alcohol-related traits (including age-at-onset, initial sensitivity, tolerance, maximum daily drinks, and a withdrawal factor score), disinhibitory symptoms, and a disinhibitory factor score in cases only. A total of 135 SNPs were genotyped using the Illumina GoldenGate and Taqman Assays-on-Demand protocols. Results Of the 101 SNPs entered into standard analysis, 6 independent SNPs from 5 DA genes were associated with AD or a quantitative alcohol-related trait. Two SNPs across 2 genes were associated with a disinhibitory symptom count, while 1 SNP in DRD5 was positive for association with the general disinhibitory factor score. Conclusions Our study provides evidence of modest associations between a small number of DA-related genes and AD as well as a range

    A significant proportion of college students are adult children of an alcoholic parent (ACoA), which can confer greater risk of depression, poor self-esteem, alcohol and drug problems, and greater levels of college attrition. However, some ACoA are resilient to these negative outcomes. The goal of this study was to better understand the psychobiological factors that distinguish resilient and vulnerable college-aged ACoAs. To do so, scholastic performance and psychological health were measured in ACoA college students not engaged in hazardous alcohol use (resilient) and those currently engaged in hazardous alcohol use (vulnerable). Neural activity (as measured by functional magnetic resonance imaging) in response to performing working memory and emotion-based tasks were assessed. Furthermore, the frequency of polymorphisms in candidate genes associated with substance use, risk taking and stress reactivity were compared between the two ACoA groups. College ACoAs currently engaged in hazardous alcohol use reported more anxiety, depression and posttraumatic stress symptoms, and increased risky nicotine and marijuana use as compared to ACoAs resistant to problem alcohol use. ACoA college students with current problem alcohol showed greater activity of the middle frontal gyrus and reduced activation of the posterior cingulate in response to visual working memory and emotional processing tasks, which may relate to increased anxiety and problem alcohol and drug behaviors. Furthermore, polymorphisms of cholinergic receptor and the serotonin transporter genes also appear to contribute a role in problem alcohol use in ACoAs. Overall, findings point to several important psychobiological variables that distinguish ACoAs based on their current alcohol use that may be used in the future for early intervention.

    Chronic alcohol consumption results in brain damage potentially reversible with abstinence. It is however difficult to gauge the degree of recovery of brain tissues with abstinence since changes are subtle and a significant portion of patients relapse. State-of-the-art morphometric methods are increasingly used in neuroimaging studies to detect subtle brain changes at a voxel level. Our aim was to use the most refined morphometric methods to observe in alcohol dependence the relationship between volumetric changes and interim drinking over a 6-month follow-up. Overall, 19 patients with alcohol dependence received volumetric T1-weighted magnetic resonance imaging (MRI) after detoxification. A 6-month follow-up study was then conducted, during which 11 of them received a second MRI scan. First, correlations were conducted between gray matter (GM) and white matter (WM) volumes of patients at alcohol treatment entry and the amount of alcohol consumed between treatment entry and follow-up. Second, longitudinal analyses were performed from pairs of MRI scans using tensor-based morphometry in the 11 patients, and correlations were computed between the resultant Jacobian maps of GM and WM and interim drinking. Our preliminary results showed that, among others, alcoholics with smaller thalamus at alcohol treatment entry tended to resume with heavy alcohol consumption (p < 0.005 uncorrected [unc.]). Our longitudinal study revealed an overall inverse relationship between recovery of brain structures like the cerebellum, striatum, and cingulate gyrus, and the amount of alcohol consumed over the 6-month follow-up (p < 0.005 unc.). The recovery could be observed not only with strict abstinence but also in cases of moderate resumption of alcohol consumption, when there had been no drastic relapse into alcohol dependence. Those preliminary findings indicate that the volume of the thalamus at treatment entry may have an influence on subsequent interim drinking. There is

    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.

    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.

    Purpose Suicide rates among military service members have risen dramatically, while drivers remain poorly understood. We aimed to examine the relationship between coincident alcohol dependence and depression in shaping subsequent risk of suicidal ideation among National Guard forces. Methods We performed a longitudinal analysis using a randomly selected, population-based sample of Ohio Army National Guard soldiers. Telephone-based surveys of 1582 soldiers who participated in both wave 1 (data collected 2008–2009) and wave 2 (data collected 2009– 2010) were analyzed. Results Incident suicidal ideation was present among 2.47% of soldiers at follow-up. Odds ratios (ORs) for suicidal ideation among those with vs. without alcohol dependence were similar among non-depressed [OR=3.85 (95% Confidence Intervals(CI) = 1.18–12.52)] and depressed individuals [OR = 3.13 (95% CI = 0.88–11.14)]; a logistic model cross-product term confirmed an absence of multiplicative interaction (beta coefficient=−0.21, p=0.82). In contrast, the risk differences (RD) for suicidal ideation among those with vs. without alcohol dependence diverged for those without depression [RD = 0.04 (95% CI = 0.02–0.07)] compared to those with depression [RD 0.11(95% CI=0.06–0.18)]; strong evidence of additive interaction was observed - [Relative Excess Risk of Interaction (RERI) = 5.978(95% CI=0.364–11.591)]. Conclusions We found that alcohol dependence and depression worked together to shape risk for incident suicidal ideation among Army National Guard service members. Because coincident alcohol dependence and depression is relatively rare, a high-risk prevention approach is recommended. Population-based screening for suicidality among patients with alcohol dependence, depression, and particularly those with both conditions is warranted in military populations. PMID:28139369

    2014-01-01

    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

    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.

    To determine whether naltrexone is beneficial in the treatment of alcohol dependence in the absence of obligatory psychosocial intervention. Multicentre, randomised, double-blind, placebo-controlled trial. Hospital-based drug and alcohol clinics, 18 March 1998 - 22 October 1999. 107 patients (mean age, 45 years) fulfilling Diagnostic and statistical manual of mental disorders (4th edition) criteria for alcohol dependence. Patients with alcohol dependence were randomly allocated to naltrexone (50 mg/day) or placebo for 12 weeks. They were medically assessed, reviewed and advised by one physician, and encouraged to strive for abstinence and attend counselling and/or Alcoholics Anonymous, but this was not obligatory. Relapse rate; time to first relapse; side effects. On an intention-to-treat basis, the Kaplan-Meier survival curve showed a clear advantage in relapse rates for naltrexone over placebo (log-rank test, chi(2)(1) = 4.15; P = 0.042). This treatment effect was most marked in the first 6 weeks of the trial. The median time to relapse was 90 days for naltrexone, compared with 42 days for placebo. In absolute numbers, 19 of 56 patients (33.9%) taking naltrexone relapsed, compared with 27 of 51 patients (52.9%) taking placebo (P = 0.047). Naltrexone was well tolerated. Unlike previous studies, we have shown that naltrexone with adjunctive medical advice is effective in the treatment of alcohol dependence irrespective of whether it is accompanied by psychosocial interventions.

    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.

    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.

    The prevalence rate of potential and pathological gambling was examined among Native American and Caucasian patients (n = 85) being treated for alcohol dependence. Previous studies with alcohol-dependent (mainly Caucasian) populations revealed 10-15% to have gambling problems. This study, the first to measure pathological gambling among a Native American population, utilized the South Oaks Gambling Screen and was administered in a group setting, between 1/91 and 4/91 on the alcohol treatment ward of the Ft. Meade Veterans Administration Hospital. Results showed that 22% of the Native Americans studied (compared to 7.3% Caucasian), scored in a range indicating a probable pathological gambling addiction. Furthermore, 41% of the Native Americans studied (compared to 21.3% Caucasian) admitted to some difficulty with gambling. Education and treatment is encouraged to help stem projected radical increases in pathological gambling and related problems among this cultural group as Native American gambling becomes widespread.

    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.

    An inpatient 28-day rehabilitation program for alcohol dependence is focused on detoxification, enhancing motivation to change, and coping strategies for the management of emotional distress and temptation to drink. The aims of the present study were to investigate 1) changes over time in motivation to change, anxiety, and depression in individuals undergoing residential rehabilitation treatment for alcohol addiction, and 2) which pretreatment factors are associated with posttreatment temptation to drink. We assessed 432 patients diagnosed with alcohol dependence based on the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) consecutively recruited from seven residential rehabilitation centers in Northern Italy. Patients were assessed by means of self-report questionnaires at the beginning of rehabilitation (pretreatment) and before their hospital discharge (posttreatment) regarding motivation to change and self-efficacy (motivation assessment of change - alcoholism version), readiness to change and temptation to drink (visual analog scales), and depression and anxiety (cognitive behavioral assessment - outcome evaluation). Results showed an overall improvement in motivation to change and a significant reduction over time in depression and anxiety levels for the total sample, particularly patients with low baseline level of temptation to drink. Multivariate linear regression analysis revealed that significant predictors of posttreatment temptation to drink were polysubstance dependence ( p <0.001), readiness to change ( p =0.01), and self-efficacy ( p =0.05). Inpatients' rehabilitation for alcohol dependence is associated with an overall improvement in motivation to change and a significant reduction of psychological distress. Treatments for alcohol-dependent patients should focus on motivation to change, negative moods, and relapse prevention strategies for the management of craving.

    2015-01-01

    Alcohol dependence is an increasing and pervasive problem. Alcohol withdrawal symptoms are a part of alcohol dependence syndrome and are commonly encountered in general hospital settings, in most of the departments. Alcohol withdrawal syndrome ranges from mild to severe. The severe complicated alcohol withdrawal may present with hallucinations, seizures or delirium tremens. Benzodiazepines have the largest and the best evidence base in the treatment of alcohol withdrawal, and are considered the gold standard. Others, such as anticonvulsants, barbiturates, adrenergic drugs, and GABA agonists have been tried and have evidence. Supportive care and use of vitamins is essential in the management. Symptom triggered regime is favoured over fixed tapering dose regime, although monitoring through scales is cumbersome. This article aims to review the evidence base for appropriate clinical management of the alcohol withdrawal syndrome. We searched Pubmed for articles published in English on ‘Alcohol withdrawal syndrome’ in humans during the last 10 years. A total of 1182 articles came up. Articles not relevant to clinical utility and management were excluded based on the titles and abstract available. Full text articles, meta-analyses, systematic reviews and randomized controlled trials were obtained from this list and were considered for review. PMID:26500991

    In alcohol-dependent patients, brain atrophy and functional brain activation elicited by alcohol-associated stimuli may predict relapse. However, to date, the interaction between both factors has not been studied. To determine whether results from structural and functional magnetic resonance imaging are associated with relapse in detoxified alcohol-dependent patients. A cue-reactivity functional magnetic resonance experiment with alcohol-associated and neutral stimuli. After a follow-up period of 3 months, the group of 46 detoxified alcohol-dependent patients was subdivided into 16 abstainers and 30 relapsers. Faculty for Clinical Medicine Mannheim at the University of Heidelberg, Germany. A total of 46 detoxified alcohol-dependent patients and 46 age- and sex-matched healthy control subjects Local gray matter volume, local stimulus-related functional magnetic resonance imaging activation, joint analyses of structural and functional data with Biological Parametric Mapping, and connectivity analyses adopting the psychophysiological interaction approach. Subsequent relapsers showed pronounced atrophy in the bilateral orbitofrontal cortex and in the right medial prefrontal and anterior cingulate cortex, compared with healthy controls and patients who remained abstinent. The local gray matter volume-corrected brain response elicited by alcohol-associated vs neutral stimuli in the left medial prefrontal cortex was enhanced for subsequent relapsers, whereas abstainers displayed an increased neural response in the midbrain (the ventral tegmental area extending into the subthalamic nucleus) and ventral striatum. For alcohol-associated vs neutral stimuli in abstainers compared with relapsers, the analyses of the psychophysiological interaction showed a stronger functional connectivity between the midbrain and the left amygdala and between the midbrain and the left orbitofrontal cortex. Subsequent relapsers displayed increased brain atrophy in brain areas associated with

    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

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.

    The association between parental history of alcoholism and the nature of alcoholism was assessed using a more reliable measure of family history (Family Tree Questionnaire) and a more comprehensive inventory of alcoholism (Alcohol Use Inventory) than used in earlier studies. Parental alcoholism was associated with more severe alcoholism on most parameters of alcohol use (age of onset, quantity, frequency, preoccupation, and sustained use) and alcohol-related problems (social, vocational, physical, cognitive, and loss of control). The association between parental history of alcoholism and more severe alcoholism in the probands was independent of age of onset of alcoholism, current age, socioeconomic background, and marital status. Parental history positive (PH+) alcoholics were more reliant on alcohol to manage their moods but did not differ significantly from parental history negative (PH-) alcoholics in the use of alcohol to improve sociability or mental functioning or to cope with marital problems. Surprisingly, the degree of concern, guilt, and worry over the negative consequences of drinking was not significantly different for PH+ alcoholics although the negative consequences were clearly much more severe for this group. While the data are inconclusive about the reasons for more severe alcoholism in PH+ alcoholics, greater reliance on ethanol to manage moods and a relative insensitivity to negative consequences could theoretically account for the vulnerability to more severe alcoholism found in PH+ alcoholics.

    To test the total consumption model claiming that alcohol-related ill health can best be diminished by a policy of severe restrictions and high price. The associations between an index measuring the severity of the alcohol policy, total alcohol consumption and number of disability-adjusted life years (DALYs) lost due to alcohol were compared in 30 OECD countries in 2005. No significant correlations were found between alcohol policy index, alcohol consumption and the number of DALYs due to alcohol use. In regression analysis, alcohol policy index and alcohol consumption were not related to alcohol-related DALYs. Excise tax rate was not related to alcohol-related DALYs (25 countries with tax rate data). These findings suggest that the total consumption model fails. Alcohol-related ill health seems to be mainly due to alcohol dependence, both clinical and subclinical, not to moderate drinking. © The Author 2015.

    Objective To date, little research exists defining bio-behavioral adaptations associated with both marijuana abuse and risk of craving and relapse to other drugs of abuse during early abstinence. Method Fifty-nine treatment-seeking individuals dependent on alcohol and cocaine were recruited. Thirty of these individuals were also marijuana (MJ) dependent; 29 were not. Twenty-six socially drinking healthy controls were also recruited. All participants were exposed to three 5-min guided imagery conditions (stress, alcohol/cocaine cue and relaxing), presented randomly, one per day across three consecutive days. Measures of craving, anxiety, heart rate, blood pressure, plasma adrenocorticotrophic hormone and cortisol were collected at baseline and subsequent recovery time points. Results The MJ-dependent group showed increased basal anxiety ratings and cardiovascular output alongside enhanced alcohol craving and cocaine craving, and dampened cardiovascular response to stress and cue. They also demonstrated elevated cue-induced anxiety and stress-induced cortisol and adrenocorticotrophic hormone levels, which were not observed in the non-MJ-dependent group or controls. Cue-related alcohol craving and anxiety were both predictive of a shorter number of days to marijuana relapse following discharge from inpatient treatment. Conclusions Findings provide some support for drug cross-sensitization in terms of motivational processes associated with stress-related and cue-related craving and relapse. PMID:23280514

    Alcohol dependence is usually comorbid with anxiety disorder, depressive disorder, or both; this comorbidity may increase drinking behavior. We previously hypothesized that anxiety-depressive alcohol dependence (ANX/DEP ALC) was a genetically specific subtype of alcohol dependence. ANX/DEP ALC may be related to dopamine and serotonin, which are catalyzed by monoamine oxidase A (MAOA) and acetaldehyde dehydrogenase 2 (ALDH2). The aim of this study was to determine whether the interaction between the MAOA and the ALDH2 genes is associated with ANX/DEP ALC. We recruited 383 Han Chinese men in Taiwan: 143 ANX/DEP ALC and 240 healthy controls. The diagnosis of ANX/DEP ALC (alcohol dependence with a past or current history of anxiety, depressive disorder, or both) was made using DSM-IV criteria. Genotypes of ALDH2 and MAOA-uVNTR (variable number of tandem repeat located upstream) were determined using PCR-RFLP. The ALDH2, but not the MAOA-uVNTR, polymorphism was associated with ANX/DEP ALC. After stratifying the MAOA-uVNTR polymorphism, we found a stronger association between the ALDH2*1/*2 and *2/*2 genotypes and the controls in the MAOA-uVNTR 4-repeat subgroup. Logistic regression significantly associated the interaction between ALDH2 and MAOA variants with ANX/DEP ALC. We conclude that the MAOA and ALDH2 genes interact in ANX/DEP ALC. Although the MAOA gene alone is not associated with ANX/DEP ALC, we hypothesize that different variants of MAOA-uVNTR polymorphisms modify the protective effects of the ALDH2*2 allele on ANX/DEP ALC in Han Chinese in Taiwan.

    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.

    Cocaine abuse has been reported as leading to impaired cognitive function. However, cocaine abusers commonly also abuse alcohol, which can itself produce cognitive impairment. This study, therefore, aimed to examine the potential confounding effect of alcohol abuse on neuropsychological test performance in cocaine and alcohol abusing individuals, comparing them with individuals who abused alcohol alone and non-abusing controls. Nineteen cocaine abusers who also met DSM-IV criteria for alcohol abuse/dependence (14 m, 5f; mean age 38.65 ± 3.83) and 20 matched individuals who met criteria for alcohol abuse/dependence alone (12 m, 8f; mean age 38.19 ± 4.82) were administered a battery of neuropsychological tests covering executive function, memory, language and visual/visuospatial function after two to four weeks of abstinence. Nineteen matched healthy controls (8 m, 11f; mean age 37.01 ± 5.98) were also tested. Both the cocaine + alcohol group and the alcohol group performed significantly more poorly than the healthy controls on the executive (ESs 2.13 and 2.57) and memory tests (ESs 0.58 and 1.06). The findings were similar for language (ESs 0.92 and 1.69), where the cocaine + alcohol abusers additionally performed significantly better than the alcohol abusers. Both patient groups were impaired on two of the five tests of visual/visuospatial function, with better performance by the cocaine + alcohol group on one of them. Chronic cocaine abuse does not appear from this study to be associated with cognitive impairment over and above that which can be attributed to co-existent alcohol abuse.

    This study examined whether depressed mood, frequency of alcohol use, and their combination differentiated non-suicidal adolescents from those with suicidal ideation and adolescents with suicidal ideation from those who have made a suicide attempt. Hierarchical logistic regressions indicated that frequency of alcohol use did not differentiate non-suicidal adolescents from those with current suicidal ideation, but severity of depressed mood did so. In contrast, alcohol use was a significant differentiating factor between adolescents who had attempted suicide compared to those with suicidal ideation only, with severity of depressed mood not being significant. However, there was also a significant interaction effect such that for adolescents with suicidal ideation and low levels of depression, increased frequency of alcohol use was associated with increased odds of a suicide attempt. These findings suggest that alcohol use may hasten the transition from suicidal ideation to suicide attempt in adolescents with low levels of depressed mood. PMID:23889515

    Despite alcohol being the most often used addictive substance among addicted patients, use of other substances such as cocaine has increased over recent years, and the combination of both drugs aggravates health impairment and complicates clinical assessment. The aim of this study is to identify and characterize heterogeneous subgroups of cocaine- and alcohol-addicted patients with common characteristics based on substance use disorders, psychiatric comorbidity and impulsivity. A total of 214 subjects with cocaine and/or alcohol use disorders were recruited from outpatient treatment programs and clinically assessed. A latent class analysis was used to establish phenotypic categories according to diagnosis of cocaine and alcohol use disorders, mental disorders, and impulsivity scores. Relevant variables were examined in the latent classes (LCs) using correlation and analyses of variance and covariance. Four LCs of addicted patients were identified: Class 1 (45.3%) formed by alcohol-dependent patients exhibiting lifetime mood disorder diagnosis and mild impulsivity; Class 2 (14%) formed mainly by lifetime cocaine use disorder patients with low probability of comorbid mental disorders and mild impulsivity; Class 3 (10.7%) formed by cocaine use disorder patients with elevated probability to course with lifetime anxiety, early and personality disorders, and greater impulsivity scores; and Class 4 (29.9%) formed mainly by patients with alcohol and cocaine use disorders, with elevated probability in early and personality disorders and elevated impulsivity. Furthermore, there were significant differences among classes in terms of Diagnostic and Statistical Manual of Mental Disorders-4th Edition-Text Revision criteria for abuse and dependence: Class 3 showed more criteria for cocaine use disorders than other classes, while Class 1 and Class 4 showed more criteria for alcohol use disorders.

    The study of 85 patients with alcohol dependence appointed to forensic psychiatric expertise in the Serbsky research center of social and forensic psychiatry revealed the manifestation of polymorphic psychiatric and behavioral disorders (ICD-10 diagnosis F10.7--residual and late-onset psychotic disorders) after stopping the intoxication, withdrawal and post-withdralwal disorders. Taking into account the multifactor etiology of psychiatric disorders which are observed after ending of the direct effect of alcohol, a possibility of including other ICD-10 items to extend their diagnostics and thus provide the more accurate clinical verification of these states, is discussed.

    Pavlovian conditioning models have led to cue-exposure treatments for drug abuse. However, conditioned responding to drug stimuli can return (be renewed) following treatment. Animal research and a previous study of social drinkers indicated that extinction is highly context dependent but that renewal could be reduced by the inclusion of a cue from the extinction context. This study extends this research to a clinical sample. Alcohol-dependent outpatients (N = 143) completed an extinction trial to reduce craving and salivation responses to alcohol cues. They were then randomized to renewal tests in either the same context as extinction, a different context, the different context containing an extinction cue, or the different context with cue plus a manipulation to increase the salience of the cue. Contrary to predictions, the different context did not produce the expected renewal effect. Although the generalization of extinction effects beyond the cue-exposure context is a positive clinical finding, it is inconsistent with basic research findings on the context dependence of extinction. Possible explanations for this inconsistency are discussed. PMID:17563145

    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.

    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.

    Carriage of rs738409:G in PNPLA3 is associated with an increased risk of developing alcohol-related cirrhosis and has a significant negative effect on survival. Short-term mortality in patients with severe alcoholic hepatitis is high; drinking behaviour is a major determinant of outcome in survivors. The aim of this study was to determine whether carriage of rs738409:G has an additional detrimental effect on survival in this patient group. Genotyping was undertaken in 898 cases with severe alcoholic hepatitis, recruited through the UK Steroids or Pentoxifylline for Alcoholic Hepatitis (STOPAH) trial, and 1188 White British/Irish alcohol dependent controls with no liver injury, recruited via University College London. Subsequent drinking behaviour was classified, in cases surviving ≥90days, as abstinent or drinking. The relationship between rs738409 genotype, drinking behaviour and survival was explored. The frequency of rs738409:G was significantly higher in cases than controls (29.5% vs. 18.9%; p=2.15×10 -15 ; odds ratio 1.80 [95% confidence interval (CI) 1.55-2.08]). Case-mortality at days 28, 90 and 450 was 16%, 25% and 41% respectively. There was no association between rs738409:G and 28-day mortality. Mortality in the 90 to 450-day period was higher in survivors who subsequently resumed drinking (hazard ratio [HR] 2.77, 95% CI 1.79-4.29; p<0.0001) and in individuals homozygous for rs738409:G (HR 1.69, 95% CI 1.02-2.81, p=0.04). Homozygosity for rs738409:G in PNPLA3 confers significant additional risk of medium-term mortality in patients with severe alcoholic hepatitis. Rs738409 genotype may be taken into account when considering treatment options for these patients. Individuals misusing alcohol who carry a particular variant of the gene PNPLA3 are more at risk of developing severe alcoholic hepatitis, a condition with a poor chance of survival. The longer-term outcome in people with this condition who survive the initial illness is strongly influenced by

    Recent studies have linked alcoholism with a dysfunctional neural reward system. Although several electrophysiological studies have explored reward processing in healthy individuals, such studies in alcohol-dependent individuals are quite rare. The present study examines theta oscillations during reward processing in abstinent alcoholics. The electroencephalogram (EEG) was recorded in 38 abstinent alcoholics and 38 healthy controls as they performed a single outcome gambling task, which involved outcomes of either loss or gain of an amount (10 or 50¢) that was bet. Event-related theta band (3.0-7.0 Hz) power following each outcome stimulus was computed using the S-transform method. Theta power at the time window of the outcome-related negativity (ORN) and positivity (ORP) (200-500 ms) was compared across groups and outcome conditions. Additionally, behavioral data of impulsivity and task performance were analyzed. The alcoholic group showed significantly decreased theta power during reward processing compared to controls. Current source density (CSD) maps of alcoholics revealed weaker and diffuse source activity for all conditions and weaker bilateral prefrontal sources during the Loss 50 condition when compared with controls who manifested stronger and focused midline sources. Furthermore, alcoholics exhibited increased impulsivity and risk-taking on the behavioral measures. A strong association between reduced anterior theta power and impulsive task-performance was observed. It is suggested that decreased power and weaker and diffuse CSD in alcoholics may be due to dysfunctional neural reward circuitry. The relationship among alcoholism, theta oscillations, reward processing, and impulsivity could offer clues to understand brain circuitries that mediate reward processing and inhibitory control.

    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.

    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

    The authors present a model for incorporating multifamily therapy in the treatment of chemical dependency and investigate the association of family participation in multifamily therapy group with treatment retention in a sample of 164 alcohol- and/or cocaine-dependent outpatients. Results indicate that level of family attendance at a multifamily group strongly predicted completion of short-term and long-term out-patient treatment. Effects were greater for cocaine-dependent than for alcohol-dependent subjects in analyses of short-term treatment retention. Multifamily therapy may be a powerful method to engage patients families in treatment and promote treatment retention, especially in the early, intensive phases of treatment for cocaine dependency.

    According to the self-medication hypothesis, individuals with depression and anxiety disorders use alcohol to control their symptoms and subsequently become dependent. Conversely, alcohol dependence disorder (ADD) can cause or exacerbate psychiatric disorders. This study analyzed the characteristics of depression and social phobia secondary to ADD. (1) What is their functional impact? (2) Are they independent or associated conditions? (3) Do they completely remit in abstinent individuals? (4) Is the remission of one disorder associated with the remission of the other disorder? Sixty-four inpatients with ADD were evaluated with depression and anxiety disorder scales upon admission to hospital and after 5 weeks of detoxification. Baseline comparisons differentiated patients with a Hamilton Rating Scale for Depression (HDRS) score > 35 (n = 50; 78%) from those with an HDRS score < or = 35 by higher levels of generalized anxiety and lower global functioning. Patients with generalized social phobia [Leibowitz Social Anxiety Scale (LSAS) score > 60: n = 20; 31.2%] were not distinguishable from those with an LSAS score < or = 60 by depressive and anxiety disorder symptoms. In postdetoxification assessment, patients who remitted from depression (HDRS score < 7: n = 35; 54.6%) had a lower generalized anxiety and marginally higher levels of hypochondriasis compared to nonremitter subjects (HDRS score > or = 7). Patients who remitted from social phobia (LSAS score < 30: n = 32; 50%) did not significantly differ from nonremitter subjects in depressive and anxiety disorder symptoms. Generalized anxiety (Hamilton Rating Scale for Anxiety) and hypochondriasis (Whiteley Index) were the significant predictors of global functioning (Global Assessment Scale). Depression and social phobia secondary to ADD are independent conditions that do not completely remit after cessation of drinking.

    To characterize the profile of patients seeking baclofen treatment for alcohol dependence in France. We compared retrospectively baclofen seekers and baclofen non-seekers within a cohort of consecutive outpatients with alcohol dependence who attended a first appointment for alcohol treatment at two French addiction centres between September 2012 and March 2014. We documented socio-demographic characteristics; comorbid psychiatric, addiction, alcohol dependence features; patients' initial drinking goal, and referral status; and treatment retention at 6 and 12 months. Of the 289 patients identified, 107 were baclofen seekers and 182 were baclofen non-seekers. The only parameters significantly associated with baclofen seekers in multivariate analyses were a greater baseline alcohol consumption (β = 15.4, 95% CI: 0.18-30.65, P = 0.05), a controlled-drinking initial goal (OR = 14.9, 95% CI: 7.7-29, P < 0.0001) and self-referral (OR = 6.6, 95% CI: 3.7-12, P < 0.0001), baclofen seekers being eight times more likely to be self-referred and treatment-naïve (OR = 8.8, 95% CI: 4.1-18.9, P < 0.0001). Baclofen seekers were more likely to be retained in treatment at 6 months (OR = 3.5, 95% CI: 1.8-6.7, P < 0.0001) and 12 months (OR = 1.9, 95% CI: 1.1-3.2, P = 0.019). In France, the perspective of controlled drinking offered by baclofen treatment may have attracted more self-referred patients, including those without previous alcohol treatment, to attend treatment, than the usual treatment options. These findings raise the question as to whether future public health strategies on alcohol should more prominently promote some aspects of alcohol treatment, such as patient's preference and treatment options, in order to reduce the treatment gap in alcohol dependence. © The Author 2016.

    Background Recent clinical trials and case-reports indicate that baclofen, a GABAB agonist, may have efficacy for alcohol dependence. Baclofen has been shown to enhance abstinence, to reduce drinking quantity, to reduce craving, and to reduce anxiety in alcohol dependent individuals in two placebo-controlled trials in Italy. However, the clinical trial data with baclofen is limited. The purpose of the present study was to test the efficacy and tolerability of baclofen in alcohol dependence in the United States. Methods The study was a double-blind, placebo-controlled, randomized study comparing 30 mg per day of baclofen to placebo over 12 weeks of treatment and utilizing eight sessions of BRENDA, a low-intensity psychosocial intervention. 121 subjects were screened to yield 80 randomized subjects (44 male) with randomization balanced for gender. Percent heavy drinking days was the primary outcome measure with other drinking outcomes, anxiety levels, and craving as secondary outcomes. Tolerability was examined. Results 76% of subjects completed the study. No difference by drug condition was seen in % heavy drinking days where on-average rates were 25.5% (± 23.6%) for placebo and 25.9% (± 23.2%) for baclofen during treatment (t(73)=0.59, p=0.56). Similarly, no differences were seen by drug condition in % days abstinent, time to first drink, or time to relapse to heavy drinking. Baclofen was associated with a significant reduction in state anxiety (F(1,73)=5.39, p=0.02). Baclofen was well tolerated with only two individuals stopping baclofen because of adverse events. There were no serious adverse events. Conclusions Baclofen, a GABAB agonist, represents a possible new pharmacotherapeutic approach to alcohol dependence. Despite encouraging preclinical data and prior positive clinical trials with baclofen in Italy, the current trial did not find evidence that baclofen is superior to placebo in the treatment of alcohol dependence.

    Patients with severe alcoholic hepatitis (SAH) have high mortality in the presence of steroid unresponsiveness in the absence of clear treatment recommendations. Liver transplantation is the curative option in such cases but is controversial in the wake of severe infections, post-transplant recidivism and long waiting on deceased donor listing. Animal and human studies have shed light on the beneficial effects of gut microbiota modulation in alcoholic liver disease. We present the first report of faecal microbiota transplantation (FMT) in a steroid non-responder in whom, clinical, biochemical and liver disease severity scores improved post-FMT and demonstrate distinct bacterial population changes pre-FMT and post-FMT. Healthy donor FMT could be safe and efficacious in SAH not responding to corticosteroid treatment, as a bridge to liver transplantation (LT) or in candidates who are unwilling or not ideal for LT for improvement in short-term transplant free survival. Larger controlled studies are required for confirmation. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    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.

    The relationship between risk-taking behavior and substance dependence has proven to be complex, particularly when examining across participants expressing a range of substance use problem severity. While main indices of risk-taking in the Balloon Analogue Risk Task (BART) positively associate with problematic alcohol use in adolescent populations (e.g., MacPherson, Magidson, Reynolds, Kahler, & Lejuez, 2010), several studies have observed a negative relationship when examining behavior within adult substance using populations (Ashenhurst, Jentsch, & Ray, 2011; Campbell, Samartgis, & Crowe, 2013). To examine potential mechanisms that underlie this negative relationship, we implemented multilevel regression models on trial-by-trial BART data gathered from 295 adult problem drinkers. These models accounted for participant behavior on trials following balloon bursts or cash outs as indices of loss and reward reactivity, respectively, and included control variables including age, IQ, and individual delay discounting rate. Results revealed that individual trial pumping was significantly predicted by trial number, and by whether or not the previous trial was a big burst or a big cash out (i.e., large magnitude of potential gains) in a manner consistent with a "near-miss" effect. Furthermore, severity of alcohol problems moderated the effect of a previous trial big burst, but not of a big cash out, on subsequent trial behavior such that those with greater severity demonstrated relative insensitivity to this "near-miss" effect. These results extend previous studies suggesting that alcohol abusers are less risky on the BART by specifying a mechanism underlying this pattern, namely, diminished reactivity to large magnitude losses.

    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.

    Rationale Alcohol addiction is a chronic relapsing disorder that presents a substantial public health problem, and is frequently comorbid with posttraumatic stress disorder (PTSD). Craving for alcohol is a predictor of relapse to alcohol use, and is triggered by cues associated with alcohol and trauma. Identification of reliable and valid laboratory methods for craving induction is an important objective for alcoholism and PTSD research. Objectives The present study compares two methods for induction of craving via stress and alcohol cues in individuals with comorbid alcohol dependence (AD) and PTSD: the combined Trier Social Stress Test and cue reactivity paradigm (Trier/CR), and a guided imagery (Scripts) paradigm. Outcomes include self-reported measures of craving, stress, and anxiety as well as endocrine measures. Methods Subjects were 52 individuals diagnosed with comorbid AD and PTSD seeking treatment at the NIAAA inpatient research facility. They participated in a four week inpatient study of the efficacy of a NK1 antagonist to treat comorbid AD and PTSD, and which included the two challenge procedures. Results Both the Trier/CR and Scripts induced craving for alcohol, as well as elevated levels of subjective distress and anxiety. The Trier/CR yielded significant increases in ACTH and cortisol, while the Scripts did not. Conclusions Both paradigms are effective laboratory means of inducing craving for alcohol. Further research is warranted to better understand the mechanisms behind craving induced by stress vs. alcohol cues, as well as to understand the impact of comorbid PTSD and AD on craving.

To investigate whether this relation extends to alcohol use disorder and clarify whether this association is non-linear. This is a cross-sectional, correlational population-based study of US adults (N = 34,653). The Alcohol Use Disorder and Associated Disabilities Interview Schedule was used to classify past-year DSM-IV alcohol use disorder and self-reported federal government-recommended weekly physical activity cutoffs. After statistically controlling for confounds, alcohol abuse but not dependence was associated with greater prevalence of physical activity. Number of alcohol use disorder symptoms exhibited a curvilinear relationship with meeting physical activity requirements, such that the positive association degraded with high symptom counts. There is a positive association between physical activity and less severe forms of alcohol use disorder in US adults. More severe forms of alcohol use disorder are not associated with physical activity.

    This study tested the hypothesis that syndromal adult antisocial behaviour (AABS) co-morbid with borderline personality disorder (BPD) is a syndrome that emerges from severe conduct disorder (CD) in childhood and adolescence and is strongly associated, in adulthood, with both violence and substance dependence. In a sample of 8 580 community-resident adults screened for the presence of personality disorders, the following predictions arising from this hypothesis were tested: first, that those with AABS co-morbid with BPD would, in comparison with those showing AABS or BPD only, show a high level of antisocial outcomes, including violence; second, that adjusting for co-morbid alcohol dependence would attenuate group differences in many of the antisocial outcomes, and violence in particular; and third, that the AABS/BPD group would show both a high prevalence and a high severity of CD, and that adjusting for co-morbid CD would attenuate any association found between AABS/BPD co-morbidity and violence. Results confirmed these predictions, suggesting that AABS/BPD co-morbidity mediates the relationship between childhood CD and a predisposition to adult violence. The triad of AABS/BPD co-morbidity, alcohol dependence and severe CD is likely associated with the risk of criminal recidivism in offenders with personality disorder following release into the community.

    This study focuses on the predictive and comparative significance of ethyl glucuronide measured in head hair (hEtG) for estimating risks associated with alcohol-impaired driving offenders. Earlier work compared different alcohol biomarkers for estimating rates of failed blood alcohol concentration (BAC) tests logged during 8 months of interlock participation. These analyses evaluate the comparative performance of several alcohol markers including hEtG and other markers, past driver records, and psychometric assessment predictors for the detection of 4 criteria: new driving under the influence (DUI) recidivism, alcohol dependence, and interlock record variables including fail rates and maximal interlock BACs logged. Drivers charged with alcohol impairment (DUI) in Alberta, Canada (n = 534; 64% first offenders, 36% multiple offenders) installed ignition interlock devices and consented to participate in research to evaluate blood-, hair-, and urine-derived alcohol biomarkers; sit for interviews; take psychometric assessments; and permit analyses of driving records and interlock log files. Subject variables included demographics, alcohol dependence at program entry, preprogram prior DUI convictions, postenrollment new DUI convictions, self-reported drinking assessments, morning and overall rates of failed interlock BAC tests, and maximal interlock BAC readings. Recidivism, dependence, high BAC, and combined fail rates were set as criteria; other variables were set as predictors. Area under the receiver operating characteristics (ROC) curve (A') estimates of sensitivity and specificity were calculated. Additional analyses were conducted on baseline hEtG levels. Driver performance and drinking indicators were evaluated against the standard hEtG cutoff for excessive drinking at (30 pg/mg) and a higher criterion of 50 pg/mg. HEtG splits were evaluated with the Mann-Whitney rank statistic. HEtG emerged as a top overall predictor for discriminating new recidivism events that

    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

    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.

    The aim of this study was to examine the relationship between urine ethanol concentration and alcohol hangover severity. N = 36 healthy social drinkers participated in a naturalistic study, comprising a hangover day and a control day. N = 18 of them have regular hangovers (the hangover group), while the other N = 18 claim to be hangover immune (hangover-immune group). On each test day at 9.30 am, urine samples were collected. Participants rated their overall hangover severity on a scale from 0 (absent) to 10 (extreme), as well as 18 individual hangover symptoms. Urine ethanol concentration was significantly higher on the hangover day when compared to the control day (p = 0.006). On the hangover day, urine ethanol concentration was significantly lower in the hangover-immune group when compared to the hangover group (p = 0.027). In the hangover-immune group, none of the correlations of urine ethanol concentration with individual hangover symptoms was significant. In contrast, in the hangover group, significant correlations were found with a variety of hangover symptoms, including nausea, concentration problems, sleepiness, weakness, apathy, sweating, stomach pain, thirst, heart racing, anxiety, and sleep problems. Urine ethanol levels are significantly associated with the presence and severity of several hangover symptoms.

    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

    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

    Research using the conditioned taste aversion procedure has reported that a cocaine/alcohol combination induces a significantly stronger taste aversion than either cocaine or alcohol alone. These findings suggest that the co-administration of alcohol intensifies the aversive effects of cocaine. Although the behavioral interaction of cocaine and alcohol is well established, little is known about how the effects of this drug combination might be modulated by a variety of subject variables. The current investigation addressed this by assessing if the ability of alcohol to potentiate cocaine-induced taste aversions is dependent upon the strain and/or sex of the subject. In this series of studies, male and female rats of Long-Evans (Experiment 1) and Sprague-Dawley (Experiment 2) descent were given limited access to a novel saccharin solution to drink and were then injected with either vehicle, cocaine (20 mg/kg), alcohol (0.56 g/kg) or the alcohol/cocaine combination. This procedure was repeated every fourth day for a total of four conditioning trials. All subjects were then compared on an Aversion Test that followed the fourth conditioning cycle. In three of the groups tested (male Long-Evans; male and female Sprague-Dawley), cocaine induced a significant taste aversion that was unaffected by the co-administration of alcohol. However, in female Long-Evans subjects, the addition of alcohol significantly strengthened the avoidance of the saccharin solution. Although the effects of alcohol on cocaine-induced taste aversions are dependent upon an interaction of sex and strain, the basis for this SexxStrain interaction is not known. That such an interaction is evident suggests that attention to such factors in assessing the effects of drug combinations is important to understanding the likelihood of the use and abuse of such drugs.

    Components of the brain reward system, i.e. the mesolimbic dopamine, laterodorsal cholinergic and ghrelin signaling systems, have been implicated in alcohol reward in preclinical studies. Genetic variants of these systems have previously been linked to alcohol dependence. Here, we genotyped 31 single nucleotide polymorphisms (SNPs): 1 SNP in the dopamine D₂ receptor (DRD2) gene, 20 SNPs in 5 different nicotinic acetylcholine receptor subunit (CHRN*) genes, and 10 SNPs in the genes encoding pro-ghrelin (GHRL) and its receptor (GHSR), in a pilot study of type 1 alcoholics (n = 84) and healthy controls (n = 32). These individuals were characterized using the Temperament and Character Inventory. None of the SNPs were associated with risk of alcohol dependence in this population. The GG genotype of SNP rs13261190 in the CHRNB3 was associated with increased novelty seeking, while SNPs of the ghrelin signaling system were associated with decreased self-directedness (AA of rs495225, GHSR) and alterations in self-transcendence (AA of both rs42451 and rs35680, GHRL). In conclusion, this pilot study suggests that reward-related genes are associated with altered personality scores in type 1 alcohol dependence, which warrants future studies of these associations in larger study samples.

    Blonanserin (BNS) is used for treatment of both positive and negative symptoms of schizophrenia in Japan and Korea. Because BNS has weak α1 receptor blocking activities and is almost devoid of histamine H1 and muscarinic M1 antagonist activity, BNS is better tolerated than other atypical antipsychotics. A high degree of D₃ receptor blockage is reported to be predictive of drug abuse and alcoholism, and BNS has strong D₃ receptor antagonism. Thus, BNS may be useful in the treatment of alcoholism. We present a case in which BNS ameliorated alcohol dependence.

    Although alcohol consumption is a common lifestyle behavior with previous studies reporting positive effects of alcohol on chronic pain and rheumatoid arthritis, no studies to this date have examined alcohol consumption in patients with fibromyalgia. We examined the association between alcohol consumption and symptom severity and quality of life (QOL) in patients with fibromyalgia. Data on self-reported alcohol consumption from 946 patients were analyzed. Subjects were grouped by level of alcohol consumption (number of drinks/week): none, low (≤ 3), moderate (>3 to 7), and heavy (>7). Five hundred and forty-six subjects (58%) did not consume alcohol. Low, moderate, and heavy levels of alcohol consumption were reported for 338 (36%), 31 (3%), and 31 patients (3%), respectively. Employment status (P <0.001), education level (P = 0.009), body mass index (P = 0.002) and opioid use (P = 0.002) differed significantly among groups with drinkers having higher education, a lower BMI, and a lower frequency of unemployment and opioid use than nondrinkers. After adjusting for these differences, the measures including the number of tender points (P = 0.01), FIQ total score (P = 0.01), physical function (P <0.001), work missed (P = 0.005), job ability (P = 0.03), and pain (P = 0.001) differed across groups, as did the SF-36 subscales of physical functioning (P <0.001), pain index (P = 0.002), general health perception (P = 0.02), social functioning (P = 0.02), and the physical component summary (P <0.001). Pairwise comparison among the 4 groups showed that the moderate and low alcohol drinkers had lower severity of fibromyalgia symptoms and better physical QOL than nondrinkers. Our study demonstrates that low and moderate alcohol consumption was associated with lower fibromyalgia symptoms and better QOL compared to no alcohol consumption. The reasons for these results are unclear. Since recent studies have demonstrated that γ-Aminobutyric Acid (GABA) levels are low in

The visit frequency based measure had no significant association with addiction outcomes. Theself-reported measure of care - when care was at a CDM clinic - was associated with lower drug addiction severity.The self-reported assessment of care from any healthcare source (CDM clinic or elsewhere)was associated with lower alcoholaddiction severity and abstinence.These findings suggest that high quality CDM for AOD dependence may improve addiction outcomes.Quality measuresbased upon alignment with the chronic care model may better capture features of effective CDM care than a visitfrequency measure.

    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.

    Gamma-aminobutyric acid (GABA)-benzodiazepine receptor function is hypothesised to be reduced in alcohol dependence. We used positron emission tomography (PET) with [11C]flumazenil, a non-selective tracer for brain GABA-benzodiazepine (GABA-BDZ) receptor binding, to determine in vivo the relationship between BDZ receptor occupancy by an agonist, midazolam, and its functional effects. Abstinent male alcohol dependent subjects underwent [11C]flumazenil PET to measure occupancy of BDZ receptors by midazolam whilst recording its pharmacodynamic effects on behavioural and physiological measures. Rate constants describing the exchange of [11C]flumazenil between the plasma and brain compartments were derived from time activity curves. A 50% reduction in electroencephalography (EEG)-measured sleep time was seen in the alcohol dependent group despite the same degree of occupancy by midazolam as seen in the control group. The effects of midazolam on other measures of benzodiazepine receptor function, increasing EEG beta1 power and slowing of saccadic eye movements, were similar in the two groups. No differences in midazolam or flumazenil metabolism were found between the groups. In summary, our study suggests that alcohol dependence in man is associated with a reduced EEG sleep response to the benzodiazepine agonist, midazolam, which is not explained by reduced BDZ receptor occupancy, and is consistent with reduced sensitivity in this measure of GABA-BDZ receptor function in alcohol dependence. The lack of change in other functional measures may reflect a differential involvement of particular subtypes of the GABA-BDZ receptor.

    We examined whether alcohol-dependent individuals with sustained substance use or psychiatric problems after completing treatment were more likely to experience low social status and whether continued help-seeking would improve outcomes. Ongoing alcohol, drug and psychiatric problems after completing treatment were associated with increased odds of low social status (unemployment, unstable housing and/or living in high-poverty neighborhood) over 7 years. The impact of drug problems declined over time, and there were small, delayed benefits of AA attendance on social status. Alcohol-dependent individuals sampled from public and private treatment programs (N = 491; 62% male) in Northern California were interviewed at treatment entry and 1, 3, 5 and 7 years later. Random effects models tested relationships between problem severity (alcohol, drug and psychiatric problems) and help-seeking (attending specialty alcohol/drug treatment and Alcoholics Anonymous, AA) with low social status (unemployment, unstable housing and/or living in a high-poverty neighborhood) over time. The proportion of participants experiencing none of the indicators of low social status increased between baseline and the 1-year follow-up and remained stable thereafter. Higher alcohol problem scores and having any drug and/or psychiatric problems in the years after treatment were associated with increased odds of low social status over time. An interaction of drug problems with time indicated the impact of drug problems on social status declined over the 7-year period. Both treatment-seeking and AA attendance were associated with increased odds of low social status, although lagged models suggested there were small, delayed benefits of AA attendance on improved social status over time. Specialty addiction treatment alone was not sufficient to have positive long-term impacts on social status and social integration of most alcohol-dependent people.

    Prior research has documented associations between mental health and alcohol use, mental health and insomnia, and insomnia and alcohol use. This study examined insomnia severity as a mediator of the association between mental health and alcohol-related outcomes in young adult veterans. Veterans aged 18-34 years (N=622, 83% male) who reported drinking in the past year completed assessments at baseline and one-month follow-up as part of a larger intervention trial. Participants reported symptoms of depression and posttraumatic stress disorder (PTSD) at baseline, insomnia severity at one month, and alcohol use and related consequences at baseline and one month. Mediation analyses using bootstrapped confidence intervals were used to examine the indirect effects of baseline mental health symptoms on alcohol-related outcomes at one month via insomnia severity. Insomnia severity was associated with both drinking quantity and alcohol-related consequences. Greater depressive (but not PTSD) symptoms were associated directly with more alcohol-related consequences. Neither depressive nor PTSD symptoms had direct effects on drinking quantity when controlling for the other mental health symptoms (e.g., depressive symptoms did not predict drinking quantity when controlling for symptoms of PTSD). However, symptoms of depression and PTSD predicted drinks per week and alcohol-related consequences indirectly through insomnia severity. Symptoms of depression and PTSD increase risk for alcohol use and related consequences in part by increasing symptoms of insomnia. Findings suggest that insomnia may be an appropriate target for prevention and intervention efforts among heavy-drinking Veterans reporting symptoms of depression or PTSD.

    Genetic studies of alcohol dependence (AD) have identified several candidate loci and genes, but most observed effects are small and difficult to reproduce. A plausible explanation for inconsistent findings may be a violation of the assumption that genetic factors contributing to each of the seven DSM-IV criteria point to a single underlying dimension of risk. Given that recent twin studies suggest that the genetic architecture of AD is complex and probably involves multiple discrete genetic factors, the current study employed common single nucleotide polymorphisms in two multivariate genetic models to examine the assumption that the genetic risk underlying DSM-IV AD is unitary. AD symptoms and genome-wide single nucleotide polymorphism (SNP) data from 2596 individuals of European descent from the Study of Addiction: Genetics and Environment were analyzed using genomic-relatedness-matrix restricted maximum likelihood. DSM-IV AD symptom covariance was described using two multivariate genetic factor models. Common SNPs explained 30% (standard error=0.136, P=0.012) of the variance in AD diagnosis. Additive genetic effects varied across AD symptoms. The common pathway model approach suggested that symptoms could be described by a single latent variable that had a SNP heritability of 31% (0.130, P=0.008). Similarly, the exploratory genetic factor model approach suggested that the genetic variance/covariance across symptoms could be represented by a single genetic factor that accounted for at least 60% of the genetic variance in any one symptom. Additive genetic effects on DSM-IV alcohol dependence criteria overlap. The assumption of common genetic effects across alcohol dependence symptoms appears to be a valid assumption. © 2015 Society for the Study of Addiction.

    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

    Alcohol use is a pervasive and costly public health problem in the United States. Relapse rates from alcohol use disorders are high. Although exercise has been proposed as a strategy to prevent relapse, lifestyle modification is the least studied aspect of relapse prevention programs, especially among racial/ethnic minority populations. The current study assessed whether being physically active was associated with remission from alcohol abuse or dependence among Black (African American and Afro Caribbean) adults in the U.S. We utilized data on Black adult participants (n = 4,828) from the nationally representative National Survey of American Life (NSAL) conducted in 2001-2003. Logistic regression models were estimated to assess the odds of being in 12-month remission or currently meeting DSM-IV criteria for alcohol abuse or dependence based on level of physical activity, adjusting for socio-demographic and neighborhood characteristics. People who endorsed being physically active had higher odds of being in 12-month remission from alcohol use problems (OR: 1.67, 95% CI: 1.28, 2.17) than people who were physically inactive, adjusting for individual- and neighborhood-level characteristics. People who were physically active did not differ significantly from those who were inactive with respect to odds of currently meeting DSM-IV criteria for alcohol abuse or dependence. Conclusions/Importance: Physical activity was positively associated with being in 12-month remission from alcohol use problems. Longitudinal studies are needed to establish temporal ordering and to explore exercise as a potential relapse prevention strategy for alcohol use problems.

    To evaluate the nutritional status and the impact of an educational intervention on nutritional behaviour in alcohol-dependent patients. A pre-and post-intervention questionnaire and a follow-up interview were administered to 58 patients of a residential alcohol treatment service. Females were at lower risk of being overweight than males, even after adjusting for amount and preferred type of alcohol beverage. Before intervention, 19% consumed 3 meals/day. Following the educational intervention, 22.2% of participants improved their knowledge. After 6 months, when 45 patients agreed to a telephone interview of whom 80% reported continued abstinence, 70.7% reported eating more than 3 meals/day. Nutritional behaviour of alcohol patients after residential treatments improved during follow-up, and it is possible that an educational intervention to increase knowledge on healthy nutrition style may have contributed.

  10. Experimental and clinical usefulness of crossmodal paradigms in psychiatry: an illustration from emotional processing in alcohol-dependence

    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

    Severe periodontitis leading to tooth loss is found in 5-15% of most populations worldwide. The applicability of salivary β -hexosaminidase (β-HEX A%, percentage of β-HEX A isoenzyme to total β-HEX) and β-HEX B% (β-HEX B/β-HEX) indexes was investigated as a possible marker of periodontitis. Thirty three alcohol-dependent smokers (AS) and 32 healthy controls (C) were enrolled in the study. The activity of β-HEX was measured spectrophotometrically. β-HEX A% was significantly higher and β-HEX B% was lower in AS than in C group. We found a significant correlation between β-HEX A% and gingival index (GI) and an inverse correlation between β-HEX A% and salivary flow (SF), in all groups. Salivary β-HEX A% index in smoking alcoholics at 0.23 had excellent sensitivity (96%) and specificity (91%); the AUC for β-HEX A% was high (0.937). There were no correlations between amount/duration-time of alcohol drinking/smoking and β-HEX A% or β-HEX B%. We found significant correlations between the time period of denture wearing and GI, papilla bleeding index (PBI), and decayed missing filled teeth index (DMFT) and between GI and the amount of smoked cigarettes per day. Bad periodontal state was most likely due to the nicotine dependence. Salivary β-HEX A% is a promising excellent marker for the diagnosis of periodontitis.

    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

    The prevalence of alcohol use disorders in Asia is increasing and relapse among treated populations remains the norm, not the exception. The extent to which cognitive impairment influences clinical outcome remains unclear, with research dominated by studies of Caucasian populations. This study examines behavioral and self-reported cognitive functioning in detoxified alcohol-dependent (AD) patients in Singapore and its association with outcome. The cognitive performance of 30 recently-detoxified AD inpatients and 30 demographically-matched controls was compared using visuospatial memory, working memory, set-shifting, planning and reflection impulsivity tests of the CANTAB®, and self-reported dysexecutive symptoms and everyday cognitive difficulties. Patients' alcohol use and self-reported cognitive functioning were reassessed 3-months post-discharge. Compared to matched controls, AD inpatients exhibited significantly poorer fluid intelligence, visuospatial memory, working memory, set-shifting flexibility and planning/organization, but not reflection impulsivity. In support of Western studies, a significant proportion (three-quarters) were "clinically impaired" on subtests. Significant reductions were observed in alcohol units, frequency and dependency scores at follow-up, though improvements in self-reported cognitive functioning were limited to abstainers. Baseline cognitive performance did not differentiate those who had abstained from alcohol and relapsed at follow-up. Memory and executive functioning impairments were evident among Asian AD patients alongside self-reported cognitive difficulties, thus cognitively demanding psychological interventions may have limited impact during early detoxification. Future studies can build on these findings, with larger samples and measurement of moderating and mediating factors to extend our understanding of how cognitive impairment influences outcome.

    2012-08-01

    From the biomedical point of view alcohol is a Janus-faced dietary component with a dose-dependent effect varying from cardiovascular protection to cytotoxicity. Alcohol is absorbed in the upper gastrointestinal tract by passive diffusion, is quickly distributed throughout body water and is mostly eliminated through oxidation. The enzymatically-catalyzed oxidative degradation to acetaldehyde and further to acetate is primarily localized in the liver. In case of a low blood alcohol concentration (<0.5 per thousand) alcohol is predominantely metabolized by the enzyme aldehyde dehydrogenase; higher blood concentrations (>0.5 per thousand) are increasingly oxidized by the microsomal ethanoloxidizing system (MEOS). Alcohol consumption induces several metabolic reactions as well as acute effects on the central nervous system. Chronic alcohol consumption to some extent irreparably damages nearly every organ with the liver being particularly concerned. There are three stages of alcohol-induced liver disease (fatty liver, alcohol hepatitis, liver cirrhosis) and the liver damages mainly result from reaction products of alcohol degradation (acetaldehyde, NADH and reactive oxygen species). An especially dreaded clinical complication of the alcohol-induced liver disease is the hepatic encephalopathy. Its pathogenesis is a multifactorial and self-perpetuating process with the swelling of astrocytes being a crucial point. Swollen astrocytes induce several reactions such as oxidative/nitrosative stress, impaired signal transduction, protein modifications and a modified gene expression profile. The swelling of astrocytes and the change in neuronal activity are attributed to several neurotoxins, especially ammonia and aromatic amino acids. In alcohol addicted subjects multiple micronutrient deficiencies are common. The status of folic acid, thiamine, pyridoxine and zinc is especially critical.

    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.

    Attention biases may be an important treatment target for both alcohol dependence and social anxiety. This is the first ABM trial to investigate two (vs. one) targets of attention bias within a sample with co-occurring symptoms of social anxiety and alcohol dependence. Additionally, we used trial-level bias scores (TL-BS) to capture the phenomena of attention bias in a more ecologically valid, dynamic way compared to traditional attention bias scores. Adult participants (N = 86; 41% Female; 52% African American; 40% White) with elevated social anxiety symptoms and alcohol dependence were randomly assigned to an 8-session training condition in this 2 (Social Anxiety ABM vs. Social Anxiety Control) by 2 (Alcohol ABM vs. Alcohol Control) design. Symptoms of social anxiety, alcohol dependence, and attention bias were assessed across time. Multilevel models estimated the trajectories for each measure within individuals, and tested whether these trajectories differed according to the randomized training conditions. Across time, there were significant or trending decreases in all attention TL-BS parameters (but not traditional attention bias scores) and most symptom measures. However, there were not significant differences in the trajectories of change between any ABM and control conditions for any symptom measures. These findings add to previous evidence questioning the robustness of ABM and point to the need to extend the effects of ABM to samples that are racially diverse and/or have co-occurring psychopathology. The results also illustrate the potential importance of calculating trial-level attention bias scores rather than only including traditional bias scores. Copyright © 2016 Elsevier Ltd.

The results also illustrate the potential importance of calculating trial-level attention bias scores rather than only including traditional bias scores. PMID:27591918

    Among the histological lesions seen in chronic hepatitis C (CHC), the presence of steatosis, bile duct lesions and lymphoid aggregates are characteristic. Recent reports suggest that steatosis is an independent risk factor for liver fibrosis in CHC. The aim of our study was to determine the relative contribution of steatosis and moderate alcohol consumption to the severity of liver fibrosis in patients infected with genotype 1 hepatitis C virus. We evaluated the patients with biopsy proven CHC and no or only moderate alcohol intake (<40 g/day). The demographical parameters of the study population, the indices of alcohol consumption: erythrocyte median corpuscular volume (MCV), gamma-glutamyl transpeptidase (GGT), the histological characteristics were noted and a statistical analysis was performed in order to determine the factors independently associated with severe fibrosis and with severe steatosis. From the 200 patients included in the study, 82 were males and 118 females, with a mean age of 47.75+/-10.42 years. At univariate analysis, advanced (grade 2, 3) fibrosis correlated with: the age at the time of biopsy, increased inflammatory activity (HAI), moderate/severe steatosis, alcohol intake, elevated GGT and MCV values. After multivariate logistic regression only age, HAI and steatosis were independently associated with advanced fibrosis stage. Regarding hepatic steatosis, from the factors found to correlate with severe steatosis at univariate analysis (alcohol intake, elevated GGT and MCV levels, severe fibrosis), after multivariate logistic regression only the elevated level of GGT was an independent prognostic factor for severe steatosis. Steatosis is an important risk factor for the severity of liver disease in CHC patients. Among patients with genotype 1 hepatitis C virus infection and moderate alcohol intake, those with serum levels of GGT over two times the normal value are at high risk for severe steatosis.

    Excessive alcohol use is common among people living with HIV. Given the growing prevalence of older HIV+ adults and observations indicating higher risk for neurocognitive impairment in older adults with either HIV infection or alcoholism, an increased understanding of their combined impact in the context of this increasingly aged population is crucial. We conducted comprehensive neurocognitive assessment in 112 older HIV+ individuals aged 50 to 69 years. Regression analyses were conducted to examine the interaction between age and the presence of lifetime alcohol dependence on neurocognitive measures, controlling for years of education, hepatitis C serostatus, and lifetime non-alcohol substance use disorder. Significant interactions of age and alcohol dependence history were found for global neurocognitive function, which was driven by the domains of executive function, processing speed, and semantic memory. Follow-up analyses indicated adverse effects of alcohol use history on neurocognitive measures that were evident only in HIV+ individuals 60 years and older. While mounting evidence in younger cohorts indicates adverse synergistic HIV/alcohol effects on neurocognitive function, our novel preliminary findings in this elderly HIV+ cohort demonstrated the importance of even a relatively distant alcohol use history on the expression of HIV-associated neurocognitive disorders that may not become apparent until much later in life.

    There is evidence that low-risk drinking is possible during the course of alcohol treatment and can be maintained following treatment. Our aim was to identify characteristics associated with low-risk drinking during treatment in a large sample of individuals as they received treatment for alcohol dependence. Integrated analysis of data from the Combined Pharmacotherapies and Behavioral Intervention (COMBINE) study, Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity) and the United Kingdom Alcohol Treatment Trial (UKATT) using repeated-measures latent class analysis to identify patterns of drinking and predictors of low-risk drinking patterns during treatment. United States and United Kingdom. Patients (n = 3589) with alcohol dependence receiving treatment in an alcohol clinical trial were primarily male (73.0%), white (82.0%) and non-married (41.7%), with an average age of 42.0 (standard deviation = 10.7). Self-reported weekly alcohol consumption during treatment was assessed using the Form-90 and validated with biological verification or collateral informants. Seven patterns of drinking during treatment were identified: persistent heavy drinking (18.7% of the sample), increasing heavy drinking (9.6%), heavy and low-risk drinking (6.7%), heavy drinking alternating with abstinence (7.9%), low-risk drinking (6.8%), increasing low-risk drinking (10.5%) and abstinence (39.8%). Lower alcohol dependence severity and fewer drinks per day at baseline significantly predicted low-risk drinking patterns [e.g. each additional drink prior to baseline predicted a 27% increase in the odds of expected classification in heavy drinking versus low-risk drinking patterns; odds ratio = 1.27 (95% confidence interval (CI) = 1.10, 1.47, P = 0.002]. Greater negative mood and more heavy drinkers in the social network were significant predictors of expected membership in heavier drinking patterns.

    We examined whether motivation to change mediated the relationships between gender and baseline alcohol severity with drinking outcome at 12-month follow-up in a longitudinal community sample. Data were from baseline and 12-month interviews from the Rural Alcohol Study, a probability sample of rural and urban at-risk drinkers (N = 733) from six southern states. At-risk drinkers were identified through a telephone-screening interview. Measures of motivation (problem recognition and taking action) were the resultant two factors derived from the Stages of Change Readiness and Treatment Eagerness Scale. Items on social consequences of drinking measured alcohol severity. Structural equation models examined relationships between baseline alcohol severity and motivation with drinks per drinking day at 12 months. We identified significant, direct paths between drinking at 12 months and alcohol severity and taking action with an unstandardized estimate of 0.116 (p < .05), alcohol severity and problem recognition (0.423, p < .01), and each of the two "motivation" latent constructs-problem recognition (1.846, p < .01) and taking action (-0.660, p < .01). Finally, the combined direct and negative effect of gender on alcohol consumption at 12-month follow-up was statistically significant, with an unstandardized estimate of -0.970 (p < .01). The current study offers evidence for motivation to change as a viable mechanism through which alcohol severity is associated with subsequent drinking outcomes. More research is needed to further explore the persistence of motivation to change on drinking outcomes over time.

    Teen binge drinking is associated with low frontal white matter integrity and increased risk of alcoholism in adulthood. This neuropathology may result from alcohol exposure or reflect a pre-existing condition in people prone to addiction. Here we used rodent models with documented clinical relevance to adolescent binge drinking and alcoholism in humans to test whether alcohol damages myelinated axons of the prefrontal cortex. In Experiment 1, outbred male Wistar rats self-administered sweetened alcohol or sweetened water intermittently for 2 weeks during early adolescence. In adulthood, drinking behavior was tested under nondependent conditions or after dependence induced by 1 month of alcohol vapor intoxication/withdrawal cycles, and prefrontal myelin was examined 1 month into abstinence. Adolescent binge drinking or adult dependence induction reduced the size of the anterior branches of the corpus callosum, i.e., forceps minor (CCFM), and this neuropathology correlated with higher relapse-like drinking in adulthood. Degraded myelin basic protein in the gray matter medial to the CCFM of binge rats indicated myelin was damaged on axons in the mPFC. In follow-up studies we found that binge drinking reduced myelin density in the mPFC in adolescent rats (Experiment 2) and heavier drinking predicted worse performance on the T-maze working memory task in adulthood (Experiment 3). These findings establish a causal role of voluntary alcohol on myelin and give insight into specific prefrontal axons that are both sensitive to alcohol and could contribute to the behavioral and cognitive impairments associated with early onset drinking and alcoholism.

    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.

    Empathy can be defined as the ability to understand the other's thoughts and feelings. It contains both cognitive and emotional components. The aim of this study was to investigate the empathy ability of patients with alcohol dependency in association with cognitive and emotional functions, after acute detoxification and during long-term abstinence. Thirty-three alcohol dependent inpatients that completed a detoxification process and stayed abstinent throughout the study, and 33 healthy comparison subjects that matched the patients for age, gender, and education level were included in the study. All the participants were administered the Facial Emotion Identification Test (FEIT), Facial Emotion Discrimination Test (FEDT), Trail Making Test (TMT), Digit Span Test (DST), Auditory Consonant Trigram Test (ACT), and Empathy Quotient Scale (EQS). All the tests were repeated after 3 months of abstinence. At the first evaluation conducted after detoxification, patients performed significantly worse than healthy comparisons in almost all tests. At the second evaluation, which was conducted after 3 months of abstinence, the patients improved significantly in all measures, and no significant differences were detected between the patient and comparison groups. There were significant correlations between the test scores and EQS score. Alcohol dependency has deleterious effects on empathy ability, and cognitive and emotional functions. Those impairments can improve with abstinence. Empathy ability has strong relationships with cognitive and emotional functions.

    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.

    Despite recognition of the harms related to alcohol misuse and its potential to interfere substantially with sustained recovery from drug dependency, research evaluating drug treatment outcomes has not addressed the issue comprehensively. It has been overlooked possibly because treatment research has been framed according to the primary drug of choice, rather than investigating the interactions between different combinations of drugs and/or alcohol use. This paper reports on a systematic review investigating whether concurrent alcohol use could impede recovery from illicit drug use in two potential ways: first, alcohol could become a substitute addiction and/or secondly, alcohol misuse post-treatment may place an individual at risk for relapse to their primary drug problem. A systematic search of four relevant databases was undertaken to identify peer-reviewed, quantitative drug treatment outcome studies that reported alcohol use pre-, post-treatment and follow-up. The search revealed 567 papers, of which 13 were assessed as fulfilling the key inclusion criteria.The review indicated inconsistent and therefore inconclusive support for the substitution hypothesis. However, the data revealed consistent support for the hypothesis that alcohol use increases relapse to drug use. (i) The potential negative impact of alcohol misuse on drug treatment outcomes remains under-researched and overlooked; (ii) alcohol consumption post-drug treatment may increase the likelihood that an individual will relapse to their primary drug; (ii) existing evidence regarding the substitution hypothesis is inconclusive, although there was an indication that a subgroup of participants will be vulnerable to alcohol becoming the primary addiction instead of drugs. We argue that future drug treatment outcome studies need to include detailed analysis of the influence of alcohol use pre- and post-drug treatment. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    The rate of relapse and involuntary hospitalization among clients with alcohol use disorder exceeds 40% in South Korea. As a result, family members of clients experience considerable stress and require the assistance of professional services. This empirical study investigates levels of perceived stress and stress coping styles among family members of clients with severe alcohol use disorder and examines the correlations among these variables. Data were collected from three inpatient alcohol rehabilitation centers and five psychiatric hospitals in South Korea. Family stress levels and stress coping styles for 133 respondents were evaluated using the Hospital Stress Rating Scale for Family Members and the Stress Coping Style Checklist. There were significant differences in stress levels according to whether participants had attended a family educational program in the past or were doing so presently. Furthermore, significant differences in stress were observed among participants who were using the stress coping style of easing strained emotions during the client's hospitalization but who had never attended an educational program. Among the subcategories, stress levels had especially strong relationships with easing strained emotions, seeking advice, and solving problems. The results showed that families with severe alcohol use disorder experience stress from the client's hospitalization and seek advice from neighbors to deal with worries, privacy concerns, and economic problems. Family interventions are needed to provide family members with strategies to cope with stress, which can support recovery of clients with severe alcohol use disorder.

    Studies on the homeostasis of magnesium in alcohol-dependent patients have often been characterized by low hypomagnesemia detection rates. This may be due to the fact that the content of magnesium in blood serum constitutes only 1% of the average magnesium level within the human body. However, the concentration of ionized magnesium is more physiologically important and makes up 67% of the total magnesium within a human organism. There are no data concerning the determination of the ionized fraction of magnesium in patients addicted to alcohol and its influence on mental health status. This study included 100 alcohol-dependent patients and 50 healthy subjects. The free magnesium fraction was determined using the potentiometric method by means of using ion-selective electrodes. The total magnesium level was determined by using a biochemical Indiko Plus analyzer. In this study, different psychometric scales were applied. Our results confirm the usefulness of ionized magnesium concentrations in erythrocytes and plasma as a diagnostic parameter of low magnesium status in alcohol-dependent patients. The lower the concentration of ionized magnesium, the worse the quality of life an alcohol-dependent person might experience. In the case of total magnesium, no such correlation was determined.

    Alcohol intake is associated with increased circulating concentrations of sex hormones, which in turn may increase hormone-dependent cancer risk. This association may be modulated by dietary fiber intake, which has been shown to decrease steroid hormone bioavailability (decreased blood concentration and increased sex hormone-binding globulin concentration). However, this potential modulation has not been investigated in any prospective cohort. Our objectives were to study the relation between alcohol intake and the risk of hormone-dependent cancers (breast, prostate, ovarian, endometrial, and testicular) and to investigate whether dietary fiber intake modulated these associations. This prospective observational analysis included 3771 women and 2771 men who participated in the Supplémentation en Vitamines et Minéraux Antioxydants study (1994-2007) and completed at least 6 valid 24-h dietary records during the first 2 y of follow-up. After a median follow-up of 12.1 y, 297 incident hormone-dependent cancer cases, including 158 breast and 123 prostate cancers, were diagnosed. Associations were tested via multivariate Cox proportional hazards models. Overall, alcohol intake was directly associated with the risk of hormone-dependent cancers (tertile 3 vs. tertile 1: HR: 1.36; 95% CI: 1.00, 1.84; P-trend = 0.02) and breast cancer (HR: 1.70; 95% CI: 1.11, 2.61; P-trend = 0.04) but not prostate cancer (P-trend = 0.3). In stratified analyses (by sex-specific median of dietary fiber intake), alcohol intake was directly associated with hormone-dependent cancer (tertile 3 vs. tertile 1: HR: 1.76; 95% CI: 1.10, 2.82; P-trend = 0.002), breast cancer (HR: 2.53; 95% CI: 1.30, 4.95; P-trend = 0.02), and prostate cancer (HR: 1.37; 95% CI: 0.65, 2.89; P-trend = 0.02) risk among individuals with low dietary fiber intake but not among their counterparts with higher dietary fiber intake (P-trend = 0.9, 0.8, and 0.6, respectively).

    An open prospective cohort study was performed in Germany in order to evaluate the costs of treating alcohol dependence under real-world conditions. Eight hundred and fourteen recently detoxified alcohol-dependent patients were provided with psychosocial rehabilitation support. In addition, 540 alcohol-dependent patients treated with adjuvant acamprosate therapy were compared with 274 patients without pharmacotherapy. Real costs were assessed over a period of one year. Of the patients who were treated with acamprosate, 33.6% remained abstinent compared to only 21.1% in the standard cohort. The mean total costs per patient treated with acamprosate were EUR 1,631.49 per year. In the standard cohort, total costs were EUR 2,068.83. This difference is highly significant (p = 0.012). Direct costs amounted to 76.9% of the total costs, with a 27% difference between the cohorts (p < 0.001). There was no difference in indirect costs between the two groups (p = 0.324). This real-cost study confirms the favourable cost-effectiveness of acamprosate previously suggested by pharmaco-economic modelling studies. Copyright 2003 S. Karger AG, Basel

    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

    Alcohol dependence is common among patients attending acute hospitals. It can be the major reason for attendance or a significant cofactor. Assessment of these patients in the acute setting can be challenging owing to the multidisciplinary approach required. Doctors in acute hospitals are often inexperienced in managing dependence, a mental health problem. They might focus on the physical harms or the withdrawal, a consequence of the dependence. For this reason, assessment of dependence and prevention and management of acute alcohol withdrawal are often suboptimal. There is little existing guidance on how to manage this patient population, especially in non-specialist settings. With recently published National Institute for Health and Clinical Excellence (NICE) guidance on the management of dependence and withdrawal, now is the perfect time to produce concise guidelines in the hope that a more succinct suite of guidance can reach a larger audience.

    Previous genomewide association studies (GWASs) have identified a number of putative risk loci for alcohol dependence (AD). However, only a few loci have replicated and these replicated variants only explain a small proportion of AD risk. Using an innovative approach, the goal of this study was to generate hypotheses about potentially causal variants for AD that can be explored further through functional studies. We employed targeted capture of 71 candidate loci and flanking regions followed by next-generation deep sequencing (mean coverage 78X) in 806 European Americans. Regions included in our targeted capture library were genes identified through published GWAS of alcohol, all human alcohol and aldehyde dehydrogenases, reward system genes including dopaminergic and opioid receptors, prioritized candidate genes based on previous associations, and genes involved in the absorption, distribution, metabolism, and excretion of drugs. We performed single-locus tests to determine if any single variant was associated with AD symptom count. Sets of variants that overlapped with biologically meaningful annotations were tested for association in aggregate. No single, common variant was significantly associated with AD in our study. We did, however, find evidence for association with several variant sets. Two variant sets were significant at the q-value <0.10 level: a genic enhancer for ADHFE1 (p = 1.47 × 10 -5 ; q = 0.019), an alcohol dehydrogenase, and ADORA1 (p = 5.29 × 10 -5 ; q = 0.035), an adenosine receptor that belongs to a G-protein-coupled receptor gene family. To our knowledge, this is the first sequencing study of AD to examine variants in entire genes, including flanking and regulatory regions. We found that in addition to protein coding variant sets, regulatory variant sets may play a role in AD. From these findings, we have generated initial functional hypotheses about how these sets may influence AD. Copyright © 2017 by the Research Society on

    Alcohol dependence is a major public health issue with a need for new pharmacological treatments. The ALPADIR study assessed the efficacy and safety of baclofen at the target dose of 180 mg/day for the maintenance of abstinence and the reduction in alcohol consumption in alcohol-dependent patients. Three hundred and twenty adult patients (158 baclofen and 162 placebo) were randomized after alcohol detoxification. After a 7-week titration, the maintenance dose was provided for 17 weeks, then progressively decreased over 2 weeks before stopping. The percentage of abstinent patients during 20 consecutive weeks (primary endpoint) was low (baclofen: 11.9%; placebo: 10.5%) and not significantly different between groups (OR 1.20; 95%CI: 0.58 to 2.50; P = 0.618). A reduction in alcohol consumption was observed from month 1 in both groups, but the difference of 10.9 g/day at month 6 between groups, in favour of baclofen, was not statistically significant (P = 0.095). In a subgroup of patients with high drinking risk level at baseline, the reduction was greater with a difference at month 6 of 15.6 g/day between groups in favour of baclofen (P = 0.089). The craving assessed with Obsessive-Compulsive Drinking Scale significantly decreased in the baclofen group (P = 0.017). No major safety concern was observed. This study did not demonstrate the superiority of baclofen in the maintenance of abstinence at the target dose of 180 mg/day. A tendency towards a reduction in alcohol consumption and a significantly decreased craving were observed in favour of baclofen. Baclofen was assessed versus placebo for maintenance of abstinence and reduction in alcohol consumption in alcohol-dependent patients. This study did not demonstrate the superiority of baclofen in the maintenance of abstinence. A tendency towards a reduction in alcohol consumption and a significantly decreased craving were observed in favour of baclofen. © The Author 2017. Medical Council on Alcohol and Oxford

    Offspring with a family history of alcohol dependence (AD) have been shown to have altered structural and functional integrity of corticolimbic brain structures. Similarly, prenatal exposure to alcohol is associated with a variety of structural and functional brain changes. The goal of this study was to differentiate the brain gray matter volumetric differences associated with familial risk and prenatal exposure to alcohol among offspring while controlling for lifetime personal exposures to alcohol and drugs. A total of 52 high-risk (HR) offspring from maternal multiplex families with a high proportion of AD were studied along with 55 low-risk (LR) offspring. Voxel-based morphometric analysis was performed using statistical parametric mapping (SPM8) software using 3T structural images from these offspring to identify gray matter volume differences associated with familial risk and prenatal exposure. Significant familial risk group differences were seen with HR males showing reduced volume of the left inferior temporal, left fusiform, and left and right insula regions relative to LR males, controlling for prenatal exposure to alcohol drugs and cigarettes. HR females showed a reduction in the right fusiform but also showed a reduction in volume in portions of the cerebellum (left crus I and left lobe 8). Prenatal alcohol exposure effects, assessed within the familial HR group, was associated with reduced right middle cingulum and left middle temporal volume. Even low exposure resulting from mothers drinking in amounts less than the median of those who drank (53 drinks or less over the course of the pregnancy) showed a reduction in volume in the right anterior cingulum and in the left cerebellum (lobes 4 and 5). Familial risk for AD and prenatal exposure to alcohol and other drugs show independent effects on brain morphology. Copyright © 2017 by the Research Society on Alcoholism.

    Objective: This study builds on previous work delineating a hierarchical model of family environmental risk in relation to a hierarchical model of externalizing disorders (EXTs) by evaluating for gene–environment interplay in these relationships. The associations between parent–child relationship quality (conflict, bonding, and management) and substance-specific adolescent family environments (parental/sibling tobacco/alcohol use) in relation to young adult EXTs (age ∼22 years nicotine, alcohol, and other drug dependence; antisocial and risky sexual behavior) were evaluated. Method: The sample included 533 adopted offspring and 323 biological offspring. Because adopted youth do not share genes with their parents, a significant association between parent–child relationship quality and EXTs would provide evidence against passive gene–environment correlation (rGE). Significant associations between parental tobacco/alcohol use in relation to offspring nicotine/alcohol dependence in the adopted offspring support common environmental influence. Significant associations detected for the biological offspring only suggest common genetic influence. Results: For both adoptive and biological offspring, there was a significant association between parent–child relationship quality and EXTs. Parental tobacco/alcohol use was unrelated to EXTs. Sibling tobacco/alcohol use was related to EXTs, but only for the biological siblings. Parental tobacco use was associated with the residual variance in nicotine dependence in adopted offspring. Conclusions: Findings replicate a long-term influence of adolescent parent–child relationship quality on adult EXTs. Findings extend previous research by providing evidence against passive rGE in this association. The association between parental tobacco use and adult nicotine dependence appears to be environmentally mediated, but caution is warranted as we found this relationship only for adopted youth.

    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.

    Exercise dependence (EXD) is considered a behavioral addiction that is often associated with eating disorders. To date, only few studies examined the potential overlap between EXD and other addictive behaviors. Therefore, the present study aimed at investigating the relationship of EXD with pathological buying, pathological video gaming (offline and online), hypersexual behavior, and alcohol use disorder in a sample of clients of fitness centers. The following questionnaires were answered by 128 individuals (age M = 26.5, SD = 6.7 years; 71.7% men, 74.2% university students): Exercise Dependence Scale, Eating Disorder Examination-Questionnaire, Compulsive Buying Scale, Pathological Computer-Gaming Scale, Hypersexual Behavior Inventory, and Alcohol Use Disorders Identification Test (AUDIT). 7.8% of the sample were at-risk for EXD, 10.9% reported eating disorder pathology, 2.3% pathological buying, 3.1% hypersexual behavior, and none of the participants suffered from pathological video gaming. The criteria for severe alcohol disorder pathology (AUDIT ≥ 16) were fulfilled by 10.2%. With regard to continuous symptom scores, EXD symptoms were positively correlated with both eating disorder pathology and pathological buying but not with pathological video gaming, hypersexuality or alcohol use disorder. It is noteworthy that more symptoms of pathological buying corresponded with more symptoms of hypersexual behavior. The correlation pattern did not differ by gender. The co-occurrence of EXD, pathological buying and hypersexual behavior on a subclinical level or in the early stage of the disorders should be taken into account when assessing and treating patients. More research is warranted in order to investigate possible interactions between these conditions.

    Following recent advances in neuromodulation therapy for mental disorders, we treated one patient with severe alcohol addiction with deep brain stimulation (DBS) of the nucleus accumbens (NAc). Before and one year following the surgery, we assessed the effects of DBS within the NAc on the addiction as well as on psychometric scores and electrophysiological measures of cognitive control. In our patient, DBS achieved normalization of addictive behavior and craving. An electrophysiological marker of error processing (the error-related negativity) linked to anterior mid-cingulate cortex (aMCC) functioning was altered through DBS, an effect that could be reversed by periods without stimulation. Thus, this case supports the hypothesis that DBS of the NAc could have a positive effect on addiction trough a normalization of craving associated with aMCC dysfunction. © 2011 The Authors, Addiction Biology © 2011 Society for the Study of Addiction.

    Alcohol is a known risk factor for TBI, yet little is known about how rates of alcohol use at time of injury differ across demographics and the stability of alcohol-related injury over time. Further, findings examining the relationship between alcohol and outcome are mixed. This study aimed to examine changes in alcohol-positive moderate-to-severe traumatic brain injury (+aTBI) over two decades with focus on demographic factors, changes in +aTBI frequency over time, mortality and acute outcome. This retrospective study examined data collected from 1992-2009 by the Pennsylvania Trauma Outcome Study (PTOS). Results reveal that the proportion of +aTBI has been generally stable across years. However, there is an interaction of +aTBI incidence with mechanism of injury and age, with a downward trend in +aTBI within MVA and fall and individuals 18-30 and 71+ years. Further, consistent with several findings in the literature, alcohol was associated with higher rates of survival and better FSD scores during acute recovery. This study discusses findings in the context of a greater literature on TBI-related alcohol and outcome. The injury-alcohol profiles highlighted could be used to inform future allocation of resources toward prevention of, intervention for and care of individuals who sustain TBI.

  4. Alcohol and the pancreas.

    Alcoholic pancreatitis may be one of the most serious adverse consequences of alcohol abuse. Its diagnosis, as it has for many years, depends primarily on clinical acumen in interpreting properly the symptoms and signs of abdominal distress, buttressed by elevated pancreatic enzymes (amylase and lipase). More recently, the use of computerized tomography (CT) in selected situations has been both of confirmatory and prognostic value. Severity of abnormality by CT correlates reasonably well with a variety of clinical-laboratory clusters (APACHE system, Ranson's criteria, etc.) and aids in therapy. The pathogenesis of alcoholic pancreatitis is not fully defined. The ultimate picture is one of tissue autolysis by activated proteolytic enzymes. The triggers for such activation, however, are still not known. They are represented by three main theories: (1) large duct obstruction and/or increased permeability relative to pancreatic secretion, (2) small duct obstruction due to proteinaceous precipitates, and (3) a direct toxic-metabolic effect of ethanol on pancreatic acinar cells. While not mutually exclusive, we favor the last hypothesis as being most consistent with the effects of ethanol on other organ systems. The direct effects of ethanol and/or its metabolites may be mediated, at least in part, via oxidative stress or the generation of fatty acid ethyl esters. Autolysis (regardless of proximate mechanism(s)) leads to inflammation likely mediated via release of various cytokines. It also should be appreciated that "acute" pancreatitis (the topic of this chapter) likely represents an acute process within a chronic pancreatic exposure and injury from alcoholic abuse. The key question of why pancreatitis develops in only a small number of alcohol abusers is not resolved. Therapy depends on the severity of alcoholic pancreatitis, which is defined by clinical-laboratory and often CT criteria. Mild pancreatitis usually resolves acutely with alcohol abstention and supportive

    Alcohol use is a risk factor for severe injury in pedestrians struck by motor vehicles. Our objective was to investigate alcohol use by bicyclists and its effects on riding behaviors, medical management, injury severity, and mortality within a congested urban setting. A hospital-based, observational study of injured bicyclists presenting to a Level I regional trauma center in New York City was conducted. Data were collected prospectively from 2012 to 2014 by interviewing all bicyclists presenting within 24 h of injury and supplemented with medical record review. Variables included demographic characteristics, scene-related data, Glasgow Coma Scale (GCS), computed tomography (CT) scans, and clinical outcomes. Alcohol use at the time of injury was determined by history or blood alcohol level (BAL) >0.01 g/dL. Of 689 bicyclists, 585 (84.9%) were male with a mean age of 35.2. One hundred four (15.1%) bicyclists had consumed alcohol prior to injury. Alcohol use was inversely associated with helmet use (16.5% [9.9–25.1] vs. 43.2% [39.1–47.3]). Alcohol-consuming bicyclists were more likely to fall from their bicycles (42.0% [32.2–52.3] vs. 24.2% [20.8–27.9]) and less likely to be injured by collision with a motor vehicle (52.0% [41.7–62.1] vs. 67.5% [63.5–71.3]). 80% of alcohol-consuming bicyclists underwent CT imaging at presentation compared with 51.5% of non-users. Mortality was higher among injured bicyclists who had used alcohol (2.9% [0.6–8.2] vs. 0.0% [0.0–0.6]). Adjusted multivariable analysis revealed that alcohol use was independently associated with more severe injury (Adjusted Odds Ratio 2.27, p = 0.001, 95% Confidence Interval 1.40–3.68). Within a dense urban environment, alcohol use by bicyclists was associated with more severe injury, greater hospital resource use, and higher mortality. As bicycling continues to increase in popularity internationally, it is important to heighten awareness about the risks and consequences of bicycling while

    The molecular mechanisms underlying alcohol dependence involve different neurochemical systems and are brain region-dependent. Chronic Intermittent Ethanol (CIE) procedure, combined with a Two-Bottle Choice voluntary drinking paradigm, represents one of the best available animal models for alcohol dependence and relapse drinking. MicroRNAs, master regulators of the cellular transcriptome and proteome, can regulate their targets in a cooperative, combinatorial fashion, ensuring fine tuning and control over a large number of cellular functions. We analyzed cortex and midbrain microRNA expression levels using an integrative approach to combine and relate data to previous protein profiling from the same CIE-subjected samples, and examined the significance of the data in terms of relative contribution to alcohol consumption and dependence. MicroRNA levels were significantly altered in CIE-exposed dependent mice compared with their non-dependent controls. More importantly, our integrative analysis identified modules of coexpressed microRNAs that were highly correlated with CIE effects and predicted target genes encoding differentially expressed proteins. Coexpressed CIE-relevant proteins, in turn, were often negatively correlated with specific microRNA modules. Our results provide evidence that microRNA-orchestrated translational imbalances are driving the behavioral transition from alcohol consumption to dependence. This study represents the first attempt to combine ex vivo microRNA and protein expression on a global scale from the same mammalian brain samples. The integrative systems approach used here will improve our understanding of brain adaptive changes in response to drug abuse and suggests the potential therapeutic use of microRNAs as tools to prevent or compensate multiple neuroadaptations underlying addictive behavior.

    In alcohol-dependent patients, alcohol-associated cues elicit brain activation in mesocorticolimbic networks involved in relapse mechanisms. Cue-exposure based extinction training (CET) has been shown to be efficacious in the treatment of alcoholism; however, it has remained unexplored whether CET mediates its therapeutic effects via changes of activity in mesolimbic networks in response to alcohol cues. In this study, we assessed CET treatment effects on cue-induced responses using functional magnetic resonance imaging (fMRI). In a randomized controlled trial, abstinent alcohol-dependent patients were randomly assigned to a CET group (n = 15) or a control group (n = 15). All patients underwent an extended detoxification treatment comprising medically supervised detoxification, health education, and supportive therapy. The CET patients additionally received nine CET sessions over 3 weeks, exposing the patient to his/her preferred alcoholic beverage. Cue-induced fMRI activation to alcohol cues was measured at pretreatment and posttreatment. Compared with pretreatment, fMRI cue-reactivity reduction was greater in the CET relative to the control group, especially in the anterior cingulate gyrus and the insula, as well as limbic and frontal regions. Before treatment, increased cue-induced fMRI activation was found in limbic and reward-related brain regions and in visual areas. After treatment, the CET group showed less activation than the control group in the left ventral striatum. The study provides first evidence that an exposure-based psychotherapeutic intervention in the treatment of alcoholism impacts on brain areas relevant for addiction memory and attentional focus to alcohol-associated cues and affects mesocorticolimbic reward pathways suggested to be pathophysiologically involved in addiction.

    Individual scale characteristics and the inventory structure of the Personality Assessment Inventory (PAI; Morey, 1991) were examined by conducting internal consistency and factor analyses of item and scale score data from a large group (N = 301) of alcohol-dependent patients. Alpha coefficients, mean inter-item correlations, and corrected item-total scale correlations for the sample paralleled values reported by Morey for a large clinical sample. Minor differences in the scale factor structure of the inventory from Morey's clinical sample were found. Overall, the findings support the use of the PAI in the assessment of personality and psychopathology of alcohol-dependent patients.

  10. Association between alcohol consumption and symptom severity and quality of life in patients with fibromyalgia

    Introduction Although alcohol consumption is a common lifestyle behavior with previous studies reporting positive effects of alcohol on chronic pain and rheumatoid arthritis, no studies to this date have examined alcohol consumption in patients with fibromyalgia. We examined the association between alcohol consumption and symptom severity and quality of life (QOL) in patients with fibromyalgia. Methods Data on self-reported alcohol consumption from 946 patients were analyzed. Subjects were grouped by level of alcohol consumption (number of drinks/week): none, low (≤3), moderate (>3 to 7), and heavy (>7). Univariate analyses were used to find potential confounders, and analysis of covariance was used to adjust for these confounders. Tukey HSD pairwise comparisons were used to determine differences between alcohol groups. Results Five hundred and forty-six subjects (58%) did not consume alcohol. Low, moderate, and heavy levels of alcohol consumption were reported for 338 (36%), 31 (3%), and 31 patients (3%), respectively. Employment status (P <0.001), education level (P = 0.009), body mass index (P = 0.002) and opioid use (P = 0.002) differed significantly among groups with drinkers having higher education, a lower BMI, and a lower frequency of unemployment and opioid use than nondrinkers. After adjusting for these differences, the measures including the number of tender points (P = 0.01), FIQ total score (P = 0.01), physical function (P <0.001), work missed (P = 0.005), job ability (P = 0.03), and pain (P = 0.001) differed across groups, as did the SF-36 subscales of physical functioning (P <0.001), pain index (P = 0.002), general health perception (P = 0.02), social functioning (P = 0.02), and the physical component summary (P <0.001). Pairwise comparison among the 4 groups showed that the moderate and low alcohol drinkers had lower severity of fibromyalgia symptoms and better physical QOL than nondrinkers. Conclusions Our study demonstrates that low and moderate

    The excited state intramolecular charge transfer reaction of 4-(1-azetidinyl)benzonitrile (P4C) has been studied in water-tertiary butanol (TBA) mixtures at different alcohol mole fractions by using steady state and time-resolved fluorescence spectroscopy. The ratio between the areas under the locally excited (LE) and charge transferred (CT) emission bands is found to exhibit a sharp rise at alcohol mole fraction approximately 0.04, a value at which several thermodynamic properties of this mixture is known to show anomalous change due to the enhancement of H-bonding network. The radiative rate associated with the LE emission also shows a maximum at this TBA mole fraction. Although the structural transition from the water-like tetrahedral network to the alcohol-like chain is reflected in the red shift of the absorption spectrum up to TBA mole fraction approximately 0.10, the emission bands (both LE and CT) show the typical nonideal alcohol mole fraction dependence at all TBA mole fractions. Quantum yield, CT radiative rate as well as transition moments also exhibit a nonideal alcohol mole fraction dependence. The time-resolved emission decay of P4C has been found to be biexponential at all TBA mole fractions, regardless of emission collection around either the LE or the CT bands. The time constant associated with the slow component (tau(slow)) shows a minimum at TBA mole fraction approximately 0.04, whereas such a minimum for the fast time constant, tau(fast) (representing the rate of LE --> CT conversion reaction) is not observed. The nonobservation of the minimum in tau(fast) might be due to the limited time resolution employed in our experiments.

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.

    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.

    DSM-IV criteria for illicit drug abuse and dependence are largely based on criteria developed for alcohol use disorders and there is a lack of research evidence on the psychometric properties of these symptoms when applied to illicit drugs. This study utilizes data on abuse/dependence criteria for cannabis, cocaine, stimulants, sedatives, tranquilizers, opiates, hallucinogens and inhalants from the National Epidemiological Survey on Alcohol and Related Conditions (NESARC, n=43 093). Analyses included factor analysis to explore the dimensionality of illicit drug abuse and dependence criteria, calculation of item difficulty and discrimination within an item response framework and a descriptive analysis of 'diagnostic orphans': individuals meeting criteria for 1-2 dependence symptoms but not abuse. Rates of psychiatric disorders were compared across groups. Results favor a uni-dimensional construct for abuse/dependence on each of the eight drug classes. Factor loadings, item difficulty and discrimination were remarkably consistent across drug categories. For each drug category, between 29% and 51% of all individuals meeting criteria for at least one symptom did not receive a formal diagnosis of either abuse or dependence and were therefore classified as 'orphans'. Mean rates of disorder in these individuals suggested that illicit drug use disorders may be more adequately described along a spectrum of severity. While there were remarkable similarities across categories of illicit drugs, consideration of item difficulty suggested that some alterations to DSM regarding the relevant severity of specific abuse and dependence criteria may be warranted.

    Objectives. We studied housing retention and its predictors in the single-site Housing First model. Methods. Participants (n = 111) were chronically homeless people with severe alcohol problems who lived in a single-site Housing First program and participated in a larger nonrandomized controlled trial (2005–2008) conducted in Seattle, Washington. At baseline, participants responded to self-report questionnaires assessing demographic, illness burden, alcohol and other drug use, and psychiatric variables. Housing status was recorded over 2 years. Results. Participants were interested in housing, although a sizable minority did not believe they would be able to maintain abstinence-based housing. Only 23% of participants returned to homelessness during the 2-year follow-up. Commonly cited risk factors—alcohol and other drug use, illness burden, psychiatric symptoms, and homelessness history—did not predict resumed homelessness. Active drinkers were more likely to stay in this housing project than nondrinkers. Conclusions. We found that single-site Housing First programming fills a gap in housing options for chronically homeless people with severe alcohol problems. PMID:24148063

    Background. Severe periodontitis leading to tooth loss is found in 5–15% of most populations worldwide. Aim. The applicability of salivary β-hexosaminidase (β-HEX A%, percentage of β-HEX A isoenzyme to total β-HEX) and β-HEX B% (β-HEX B/β-HEX) indexes was investigated as a possible marker of periodontitis. Methods. Thirty three alcohol-dependent smokers (AS) and 32 healthy controls (C) were enrolled in the study. The activity of β-HEX was measured spectrophotometrically. Results. β-HEX A% was significantly higher and β-HEX B% was lower in AS than in C group. We found a significant correlation between β-HEX A% and gingival index (GI) and an inverse correlation between β-HEX A% and salivary flow (SF), in all groups. Salivary β-HEX A% index in smoking alcoholics at 0.23 had excellent sensitivity (96%) and specificity (91%); the AUC for β-HEX A% was high (0.937). There were no correlations between amount/duration-time of alcohol drinking/smoking and β-HEX A% or β-HEX B%. We found significant correlations between the time period of denture wearing and GI, papilla bleeding index (PBI), and decayed missing filled teeth index (DMFT) and between GI and the amount of smoked cigarettes per day. Conclusion. Bad periodontal state was most likely due to the nicotine dependence. Salivary β-HEX A% is a promising excellent marker for the diagnosis of periodontitis. PMID:24288426

    Many studies have reported medication effects on alcohol cue-elicited brain activation or associations between such activation and subsequent drinking. However, few have combined the methodological rigor of a randomized clinical trial (RCT) with follow-up assessments to determine whether cue-elicited activation predicts relapse during treatment, the crux of alcoholism. This study analyzed functional magnetic resonance imaging (fMRI) data from 48 alcohol-dependent subjects enrolled in a 6-week RCT of an investigational pharmacotherapy. Subjects were randomized, based on their level of alcohol withdrawal (AW) at study entry, to receive either a combination of gabapentin (GBP; up to 1,200 mg for 39 days) and flumazenil (FMZ) infusions (2 days) or two placebos. Midway through the RCT, subjects were administered an fMRI alcohol cue reactivity task. There were no main effects of medication or initial AW status on cue-elicited activation, but these factors interacted, such that the GBP/FMZ/higher AW and placebo/lower AW groups, which had previously been shown to have relatively reduced drinking, demonstrated greater dorsal anterior cingulate cortex (dACC) activation to alcohol cues. Further analysis suggested that this finding represented differences in task-related deactivation and was associated with greater control over alcohol-related thoughts. Among study completers, regardless of medication or AW status, greater left dorsolateral prefrontal cortex (DLPFC) activation predicted more post-scan heavy drinking. These data suggest that alterations in task-related deactivation of dACC, a component of the default mode network, may predict better alcohol treatment response, while activation of DLPFC, an area associated with selective attention, may predict relapse drinking.

    Oral naltrexone reduces heavy drinking, but is less consistent as an abstinence promoter, whereas once-monthly extended-release naltrexone (XR-NTX) also maintains abstinence. The present study sought to determine if alcohol cue reactivity is attenuated by XR-NTX. Twenty-eight detoxified alcohol-dependent adult male and female volunteers received a single i.m. injection of either XR-NTX or placebo under double-blind conditions. An fMRI/cue reactivity procedure was conducted immediately before and two weeks after injection. At baseline, alcohol-related visual and olfactory cues elicited significant increases in orbital and cingulate gyri, inferior frontal and middle frontal gyri. Subsequently, brain activation was significantly altered in XR-NTX-treated individuals. These affected brain regions are associated with the integration of emotion, cognition, reward, punishment, and learning/memory, suggesting that XR-NTX attenuates the salience of alcohol-related cues. Such an effect on brain function may interrupt the processes associated with "slips" and relapse, which may account for XR-NTX's ability to maintain abstinence. Copyright © 2013 Elsevier Inc.
