    With the exception of cardiovascular diseases, no other medical condition causes more serious dysfunction or premature deaths than alcohol-related problems. Research results indicate that alcohol dependent individuals present an exceptionally poor level of quality of life. This is an outcome that highlights the necessity of planning and implementing preventive interventions on biological, psychological or social level, to be provided to individuals who make alcohol abuse, as well as to their families. Preventive interventions can be considered on three levels of prevention: (a) primary prevention, which is focused on the protection of healthy individuals from alcohol abuse and dependence, and may be provided on a universal, selective or indicated level, (b) secondary prevention, which aims at the prevention of deterioration regarding alcoholic dependence and relapse, in the cases of individuals already diagnosed with the condition and (c) tertiary prevention, which is focused at minimizing deterioration of functioning in chronically sufferers from alcoholic dependence. The term "quaternary prevention" can be used for the prevention of relapse. As for primary prevention, interventions focus on assessing the risk of falling into problematic use, enhancing protective factors and providing information and health education in general. These interventions can be delivered in schools or in places of work and recreation for young people. In this context, various programs have been applied in different countries, including Greece with positive results (Preventure, Alcolocks, LST, SFP, Alcohol Ignition Interlock Device). Secondary prevention includes counseling and structured help with the delivery of programs in schools and in high risk groups for alcohol dependence (SAP, LST). These programs aim at the development of alcohol refusal skills and behaviors, the adoption of models of behaviors resisting alcohol use, as well as reinforcement of general social skills. In the

    Insomnia during acute alcohol withdrawal (AWD) as well as persisting insomnia during post-acute withdrawal is associated with relapse. Rates of insomnia in clinical samples of alcohol-dependent patients range from 36 to 91%, but the prevalence of AWD-related insomnia in the general population is unknown. The purpose of this study was to describe the prevalence of insomnia as a symptom of acute AWD and its correlates in a general population of alcohol-dependent individuals. Data were analyzed ...

    Continued excessive alcohol consumption can lead to the development of dependence that is associated with a withdrawal syndrome when alcohol consumption is ceased or substantially reduced. This syndrome comprises physical signs as well as psychological symptoms that contribute to distress and psychological discomfort. For some people the fear of withdrawal symptoms may help perpetuate alcohol abuse; moreover, the presence of withdrawal symptoms may contribute to relapse after periods of absti...

    Researchers are using various strategies to identify the genes that may be associated with alcoholism. The initial efforts primarily relied on candidate gene and linkage studies; more recently, however, modern advances in genotyping have resulted in widespread use of genome-wide association studies for alcohol dependence. The key findings of the earlier studies were that variations (i.e., polymorphisms) in the DNA sequences of the genes encoding alcohol dehydrogenase 1B (i.e., the ADH1B gene)...

    1994-12-01

    The vending machines which sell alcohol beverages (AVM) can be found quite easily in front of shops or on the roadside in this country. Although it is easily supposed that these vending machines might have badly influenced on developing alcohol dependence syndrome, no scientific study has been reported in this regard so far. In this study, we analyzed the present status of alcoholics (n = 759) and their family members (n = 512) and of ordinary people (n = 334) in terms of their "relation" and "attitudes" to the vending machines by a questionnaire method. The results obtained show as follows: The majority of alcoholics (60%) had used AVM a couple of times or more often in a week, and 18% of alcoholics had not used AVM at all. It was found that the natures of AVM such as "machine," "long time operation," "easy accessibility," are closely related to the development of their alcohol seeking behavior, resulting in forming unfavorable drinking patterns such as concealed drinking, gulping, early morning drinking or binge drinking. Unusual patterns of using AVM were also noticed among them, such as, go to AVM before 5 a.m. and wait until it starts to work, go to a far away AVM deliberately, or, visiting AVM one after another. It was noticed that these drinking habits affected seriously not only the alcoholics but their families also. The number of the family members who insisted that AVM affected badly on the course of alcohol dependence syndrome is larger than that of alcoholics who admit the same thing. As for the future abolition of AVM, 91% of the family members, 70% of alcoholics and 39% of ordinary persons agreed with. The rate of "agreed with abolition" is higher than that of "disagreed with abolition" among ordinary persons. PMID:7695515

    1995-06-01

    While psychological conflict about dependency needs of alcoholic and obese persons has been widely observed, few studies have examined differences in dependency characteristics between these clinical groups. The Interpersonal Dependency Inventory was administered to 22 alcoholic and 8 morbidly obese men in intensive treatment for alcohol and obesity. The original hypothesis that alcoholic and obese men would show similar dependency needs was supported. Dependency correlates of personality may serve as useful predictor variables in the clinical treatment of alcoholic and obese persons.

    The genetic determinants of alcoholism still are largely unknown, hindering effective treatment and prevention. Systematic approaches to gene discovery are critical if novel genes and mechanisms involved in alcohol dependence are to be identified. Although no animal model can duplicate all aspects of alcoholism in humans, robust animal models for specific alcohol-related traits, including physiological alcohol dependence and associated withdrawal, have been invaluable resources.

    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.

  17. A heuristic model of alcohol dependence.

    Zhen Qi

    Full Text Available BACKGROUND: Substance dependence poses a critical health problem. Sadly, its neurobiological mechanisms are still unclear, and this lack of real understanding is reflected in insufficient treatment options. It has been hypothesized that alcohol effects are due to an imbalance between neuroexcitatory and neuroinhibitory amino acids. However, glutamate and GABA interact with other neurotransmitters, which form a complicated network whose functioning evades intuition and should be investigated systemically with methods of biomedical systems analysis. METHODS AND RESULTS: We present a heuristic model of neurotransmitters that combines a neurochemical interaction matrix at the biochemical level with a mobile describing the balances between pairs of neurotransmitters at the physiological and behavioral level. We investigate the effects of alcohol on the integrated neurotransmitter systems at both levels. The model simulation results are consistent with clinical and experimental observations. The model demonstrates that the drug diazepam for symptoms of alcohol withdrawal effectively reduces the imbalances between neurotransmitters. Moreover, the acetylcholine signal is suggested as a novel target for treatment of symptoms associated with alcohol withdrawal. CONCLUSIONS: Efficient means of integrating clinical symptoms across multiple levels are still scarce and difficult to establish. We present a heuristic model of systemic neurotransmitter functionality that permits the assessment of genetic, biochemical, and pharmacological perturbations. The model can serve as a tool to represent clinical and biological observations and explore various scenarios associated with alcohol dependence and its treatments. It also is very well suited for educational purposes.

    Full Text Available Alcohol dependence is a global concern. Baclofen has shown promise as an anti-craving agent but its efficiency remains to be settled. We reviewed 549 male cases diagnosed with alcohol dependence who received Acamprosate (201 or Baclofen (348. ′Time to first drink′ was compared between two groups and multiple regression analysis was done in baclofen group to identify correlates of effectiveness. There was a significant difference in outcome measure between Baclofen (M = 4.44, SD = 3.75 and Acamprosate group (M = 3.73, SD = 2.19; t (547 = 2.45, P = 0.01. Initial regression analysis with six predictor variables (average daily alcohol units, current age, age at onset of dependence, family history, duration of dependence and dose of baclofen in mg/day showed significant correlation of outcome variable with only two predictor variables - dose of baclofen and average daily intake. Using the hierarchical method it was found that ′dose of baclofen′ and ′average alcohol intake′ explain a significant amount of variance in ′time to first drink′. [F (1, 345 = 182.8, P < 0.001, R2 = 0.52, R2 adjusted = 0.51]. This information can be used to select patients in long term longitudinal studies and may explain variable results seen in clinical trials of baclofen done earlier.

    Full Text Available Objective: Alcohol addiction too often remains insufficiently treated. It shows the same profile as severe chronic diseases, but no comparable, effective basic treatment has been established up to now. Especially patients with repeated relapses, despite all therapeutic approaches, and patients who are not able to attain an essential abstinence to alcohol, need a basic medication. It seems necessary to acknowledge that parts of them need any agonistic substance, for years, possibly lifelong. For >14 years, we have prescribed such substances with own addictive character for these patients.Methods: We present a documented best possible practice, no designed study. Since 1997, we prescribed Dihydrocodeine (DHC to 102 heavily alcohol addict-ed patients, later, also Buprenorphine, Clomethiazole (>6 weeks, Baclofen and in one case Amphetamine, each on individual indication. This paper focuses on the data with DH, especially. The Clomethiazole-data has been submitted to a German journal. The number of treatments with the other substances is still low. Results: The 102 patients with the DHC-treatment had 1367 medically assisted detoxifications and specialized therapies before! The 4 years-retention rate was 26.4%, including 2.8% successfully terminated treatments. In our 12-step scale on clinical impression, we noticed a significant improvement from mean 3.7 to 8.4 after 2 years. The demand for medically assisted detoxifications in the 2 years remaining patients was reduced by 65.5%. Mean GGT improved from 206.6 U/l at baseline to 66.8 U/l after 2 years. Experiences with the other substances are similar but different in details.Conclusions: Similar to the Italian studies with GHB and Baclofen, we present a new approach, not only with new substances, but also with a new setting and much more trusting attitude. We observe a huge improvement, reaching an almost optimal, stable, long term status in around ¼ of the patients already. Many further

    Previous findings have shown that rumination predicts alcohol abuse independently of depression. However, the literature does not inform about the relationships between alcohol dependence and functional and dysfunctional rumination. It has indeed been suggested that there exist a functional form of rumination(concrete thinking) and a dysfunctional form of rumination (abstract thinking). In this study, our aim is to evaluate if alcohol dependence is similarly associated with functional/constru...

    Full Text Available Alcohol abuse and alcoholism are the leading causes of worse health and increased mortality rates. Excessive alcohol consumption is the third leading cause of the global burden of diseases and a leading factor for lower lifespan and higher mortality. Alcohol abuse decreases working capacity and efficiency and requires the increased cost of the treatment of alcohol-induced disorders, which entails serious economic losses. The unfavorable medical and social consequences of excessive alcohol use determine the importance of effective treatment for alcoholism. The goals of rational pharmacotherapy of alcohol dependence are to enhance GABA neurotransmission, to suppress glutamate neurotransmission, to act on serotonin neurotransmission, to correct water-electrolyte balance, and to compensate for thiamine deficiency. Alcoholism treatment consists of two steps: 1 the prevention and treatment of alcohol withdrawal syndrome and its complications (withdrawal convulsions and delirium alcoholicum; 2 antirecurrent (maintenance therapy. Benzodiazepines are the drugs of choice in alleviating alcohol withdrawal and preventing its convulsive attacks and delirium alcoholicum. Diazepam and chlordiazepoxide are most commonly used for this purpose; the safer drugs oxazepam and lorazepam are given to the elderly and patients with severe liver lesions. Anticonvulsants having normothymic properties, such as carbamazepine, valproic acid, topiramate, and lamotrigine, are a definite alternative to benzodiazepines. The traditional Russian clinical practice (clearance detoxification has not a scientific base or significant impact on alcohol withdrawal-related states in addicts. Relapse prevention and maintenance therapy for alcohol dependence are performed using disulfiram, acamprosate, and naltrexone; since 2013 the European Union member countries have been using, besides these agents, nalmefene that is being registered in Russia.

    Full Text Available Background: Alcohol-dependent patients are traditionally believed to have insecure attachment styles, higher anger expression, and lower self-esteem. There is a need to study them together. Aim: To understand the relationships amongst various of the socio-emotional factors. Materials and Methods: Forty male patients with Alcohol dependence syndrome and 40 matched healthy controls (General Health Questionnaire-12 score <3 were compared on attachment styles (on Relationship Scale Questionnaire, anger domains (on State Trait Anger Expression Inventory, and self-esteem (on Rosenberg Self-esteem Scale. Statistics and Analysis: Comparison using independent samples t test and chi square test; correlation using Pearson′s correlation coefficient. Results: Patients had significantly higher anger expression, ′anger in′ and ′anger out,′ and lower self-esteem than healthy controls. Severity of alcohol dependence had significant correlation with ′anger out,′ and self-esteem had significant negative correlation with anger expression. Conclusion: The present study suggests that the socio-emotional factors studied are developmentally linked to each other.

    Full Text Available Alcohol misuse is generally not detected in hospital settings. The goal of this study was to estimate the prevalence of alcohol abuse and dependence in hospitalized patients in a university hospital in Sao Paulo (Brazil. Patients were randomly selected from all hospital admissions. The final sample consisted of 169 adult inpatients. Two screening tools were used: the Short Alcohol Dependence Data (SADD and the CAGE questionnaires. In this sample, 25.4% of patients could be considered alcohol dependent according to the CAGE questionnaire, whereas 32.9% of patients fulfilled the criteria according to the SADD. The only predictor of alcohol dependence was gender; male inpatients were 3.2 times more prone to alcohol dependence with female inpatients. All inpatients should be systematically screened for alcohol use disorders. The choice of the screening tool will depend on whether the goal is to identify inpatients with hazardous drinking behaviors or with established alcohol-related problems. To maximize proper case identification, the CAGE questionnaire should be used as a first-step screening tool, and patients who screen positive on this scale should be subsequently administered the SADD questionnaire to assess the severity of the condition.

    Full Text Available BACKGROUND Gambling has been a part of human behaviour since prehistory. Past global studies show that rates of pathologic gambling are 4 to 10 times higher for substance abusers than for the general population. Alcohol dependence is also more common among parents of pathologic gamblers. Studies from India have been very few on this subject. OBJECTIVES The objectives were to analyse the prevalence of gambling behaviour in alcohol dependent individuals, to assess whether alcohol influence had effect on gambling behaviour, to analyse if gambling behaviour was associated with personality traits, to explore the possibility whether alcohol use & gambling behaviour in parents had influence on the gamblers. METHODS A sample of 100 consecutive male patients attending de-addiction OPD of a Government Tertiary Care Hospital in Chennai was selected. Those who had a diagnosis of alcohol dependence were screened for gambling and assessed using the South Oaks Gambling Screen (SOGS and Eysenck’s Personality Questionnaire. History of gambling behaviour and alcohol use in parents were correlated. RESULTS A high incidence of gambling related problems in alcohol dependent individuals was found. Among them, 24% had gambling related problems, of which 11% amounted to pathologic gambling. Age, Marital status, Residential locality, Economic status, Educational levels, or being under the influence of alcohol did not correlate with the gambling behaviour. Extrovert personality, alcohol dependence in father, and family history of gambling were more common in problem/pathologic gamblers.

This common genetic liability, which also extends to antisocial behavior, has been conceptualized as a general predisposition toward a variety of forms of psychopathology charac...

    About 85% of the adult population in the Netherlands regularly drinks alcohol. Chronic excessive alcohol intake in alcohol-dependent individuals is known to have damaging effects on brain structure and function. Relatives of alcohol-dependent individuals display differences in brain function that are similar to those found in alcoholics, even if they have never been drinking alcohol. This suggests that brain damage in alcohol-dependent individuals is at least partly related to genetic factors...

    Nalmefene is the first available drug approved in the E.U. to reduce alcohol use in alcohol-dependent patients. Reduction in alcohol use in heavy drinkers diminishes mortality risk and socio-economic burden. Nalmefene has shown efficacy at 6 months in alcohol-dependent patients with high or very high drinking risk levels in reducing total alcohol consumption (-7.6 g/day [95% confidence interval (CI): -11.6 to -3.5]; P = 0.0003), heavy drinking days (-2.00 days/month [95% CI: -3.00 to -1.00]; P ⟨ 0.00001) and other secondary outcome measures such as γ-glutamyl transferase, alanine aminotransferase, drinking risk level and Clinical Global Impression. It is generally well tolerated and has limited contraindications and interactions. As-needed dosage is a novel concept in the addictions field, which may overcome limitations of traditional regimens. In the pivotal trials, nalmefene was taken 52% of the days and compliance with the as-needed treatment regimen was good (above 80% of the days) in 68% of the nalmefene-treated patients. A new pharmacological approach combined with a brief psychosocial intervention for alcoholism is available and appears to be feasible, safe and efficacious. PMID:24918835

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

    Full Text Available François Paille, Hervé Martini Department of Addiction Treatment, University Hospital, Vandœuvre-lès-Nancy, France Abstract: Reduction of alcohol consumption is not yet a widely accepted treatment objective for alcohol-dependent patients, as abstinence is often considered to be the only possible objective in this situation. However, various studies have demonstrated the value of proposing these two options to such patients. Firstly, reduction of alcohol consumption very significantly reduces the risk of alcohol-related damage, and also modifies the patient's and the doctor's perception of the disease, resulting in improved access to care and better patient adherence with the proposed treatment objective and consequently better clinical results. Recent studies have shown that some medicinal products can help patients reduce their alcohol consumption. One such product, nalmefene, has been granted European marketing authorization and is now being released onto the market in various countries. The ESENSE 1 and 2 studies in alcohol-dependent patients showed that, in combination with BRENDA, a psychosocial intervention focusing on reinforcement of motivation and treatment adherence, nalmefene significantly reduced the number of heavy drinking days and mean daily total alcohol consumption versus placebo. This reduction was more marked in the marketing authorization target population, ie, patients with a high or very high drinking risk level according to World Health Organization criteria. Another original feature of this molecule is that it can be used as needed if the patient perceives a risk of drinking, which is a more flexible approach and more likely to ensure the patient's active involvement in the treatment of his/her disease. This molecule opens up interesting and original therapeutic prospects in the treatment of alcohol dependence.

    Background and Objectives The ways in which homeless individuals cope with stress may differ from those relied upon by the members of the general population and these differences may either be the result or the cause of their living conditions. The aim of the study was to determine the preferred coping style among the homeless and its relationship with alcohol dependence. Methods The study included 78 homeless individuals and involved the collection of demographic, sociological, psychological and medical data from each participant. Coping styles relied upon when dealing with stressful situations were assessed using a Polish adaptation of the Coping Inventory for Stressful Situations. Alcohol dependence was assessed using the Michigan Alcoholism Screening Test (MAST) and a quantitative analysis of alcohol consumption. Results Men accounted for 91.93% of the study population. Nearly 75% of the subjects met the alcohol dependence criterion. Significant relationships were observed between the individual's age, preferred coping style and alcohol consumption level. As an individual’s age increased, the use of emotion-oriented coping styles decreased, while an increase in alcohol consumption was associated with a more frequent use of emotion- and avoidance-oriented strategies. Conclusions The findings of this study, similarly to those of many other studies of homeless individuals but investigating other areas (e.g. epidemiology of tuberculosis and traumatic injuries), are an exaggerated representation of associations observed in the general population. The results describe a group of people living on the margins of the society, often suffering from extremely advanced alcoholism, with clear evident psychodegradation. The presence of specific ways of coping with stress related to excessive alcohol consumption in this group of individuals may interfere with active participation in support programmes provided for the homeless and may further exacerbate their problems.

    2009-12-01

    Full Text Available Alcohol dependence is a heavy burden on patients, their families, and society. Epidemiological studies indicate that alcohol dependence will affect many individuals at some time in their lives, with men affected more frequently than women. Since alcohol-dependent patients often exhibit a lack of social skills and suffer from interpersonal problems, the aim of this study is to elucidate whether men and women experience the same interpersonal problems. Eighty-five alcohol-dependent patients (48 men; 37 women after detoxification and 62 healthy controls (35 men; 27 women were recruited. Interpersonal problems were measured with the Inventory of Interpersonal Problems (IIP-64. Additionally, alcohol-dependent patients were interviewed with the Alcohol Use Disorders Identification Test (AUDIT and were subtyped according to Lesch’s Alcohol Typology (LAT. There were no significant gender differences in the AUDIT and LAT between alcohol-dependent men and women. Interpersonal problems of alcohol-dependent men differed significantly in one out of eight dimensions from controls; alcohol-dependent men perceive themselves as colder than male controls. Alcohol-dependent women differed in four out of eight interpersonal dimensions from female controls. Alcohol-dependent women rated themselves as significantly more vindictive, more introverted, more overly accommodating and more intrusive than female controls. Results suggest that alcohol-dependent men and women suffer from different interpersonal problems and furthermore alcohol-dependent women perceive more interpersonal problems, whereas the severity of alcohol dependence did not differ between the groups. Our findings indicate that alcohol-dependent women may profit more from a gender-specific treatment approach aimed at improving treatment outcome than alcohol-dependent men.

    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.

  5. Cue reactivity is associated with duration and severity of alcohol dependence: an FMRI study.

    Directory of Open Access Journals (Sweden)

    Zsuzsika Sjoerds

    Full Text Available INTRODUCTION: With the progression of substance dependence, drug cue-related brain activation is thought to shift from motivational towards habit pathways. However, a direct association between cue-induced brain activation and dependence duration has not yet been shown. We therefore examined the relationship between alcohol cue-reactivity in the brain, cue-induced subjective craving and alcohol dependence duration and severity. Since alcohol dependence is highly comorbid with depression/anxiety, which may modulate brain responses to alcohol cues, we also examined the relation between comorbid depression/anxiety and cue-reactivity. METHODS: We compared 30 alcohol dependent patients with 15 healthy controls and 15 depression/anxiety patients during a visual alcohol cue-reactivity task using functional magnetic resonance imaging blood oxygenated level-dependent responses and subjective craving as outcomes. Within the alcohol dependent group we correlated cue-reactivity with alcohol dependence severity and duration, with cue-induced craving and with depression/anxiety levels. RESULTS: Alcohol dependent patients showed greater cue-reactivity in motivational brain pathways and stronger subjective craving than depression/anxiety patients and healthy controls. Depression/anxiety was not associated with cue-reactivity, but depression severity in alcohol dependent patients was positively associated with craving. Within alcohol dependence, longer duration of alcohol dependence was associated with stronger cue-related activation of the posterior putamen, a structure involved in habits, whereas higher alcohol dependence severity was associated with lower cue-reactivity in the anterior putamen, an area implicated in goal-directed behavior preceding habit formation. CONCLUSION: Cue-reactivity in alcohol dependence is not modulated by comorbid depression or anxiety. More importantly, the current data confirm the hypothesis of a ventral to dorsal striatal shift

    Alcoholism is a complex genetically influenced disorder which refers to alcohol abuse and alcohol dependence. There are controversial results on the role of gene polymorphisms in alcohol dependence in the literature. Differences in population groups and selective inclusion criteria for alcohol dependence may affect results. In this study, we investigated the role of ADH1B Arg48His (rs1229984) and, ADH1C Ile350Val (rs698) gene polymorphisms in Turkish population. 100 healthy volunteers and 75 patients who were admitted to Ege University Alcohol Dependence Unit enrolled in the study. We found significant increase both in ADH1B (Arg48His) polymorphism Arg allele and Arg/Arg genotype frequency in patients. No profound connection between alcohol dependence and ADH1C Ile350Val gene polymorphism was detected. Alcohol dependence is an important health problem that depends on many genetic and environmental factors but we think that it is possible to interpret genetic risk for developing early diagnostic methods and treatment strategies by comprehensive linkage and association studies.

    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.

    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

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. Results 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. Conclusion 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.

    Chronic alcohol abuse is often co-morbid with depression symptoms and in many cases it appears to induce major depressive disorder. Structural and functional neuroimaging has provided evidence supporting some degree of neuropathological convergence of alcoholism and mood disorders. In order to understand the cellular neuropathology of alcohol dependence and mood disorders, postmortem morphometric studies have tested the possibility of alterations in the number and size of cells in the prefron...

    Full Text Available 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 ADH2FNx012 (0.50, ADH3FNx011 (0.67 and ALSH2FNx012 (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.

    Association between Y chromosome haplotype variation and alcohol dependence and related personality traits was investigated in a large sample of psychiatrically diagnosed Finnish males. Haplotypes were constructed for 359 individuals using alleles at eight loci (seven microsatellite loci and a nucleotide substitution in the DYZ3 alphoid satellite locus). A cladogram linking the 102 observed haplotype configurations was constructed by using parsimony with a single-step mutation model. Then, a series of contingency tables nested according to the cladogram hierarchy were used to test for association between Y haplotype and alcohol dependence. Finally, using only alcohol-dependent subjects, we tested for association between Y haplotype and personality variables postulated to define subtypes of alcoholism-antisocial personality disorder, novelty seeking, harm avoidance, and reward dependence. Significant association with alcohol dependence was observed at three Y haplotype clades, with significance levels of P = 0.002, P = 0.020, and P = 0.010. Within alcohol-dependent subjects, no relationship was revealed between Y haplotype and antisocial personality disorder, novelty seeking, harm avoidance, or reward dependence. These results demonstrate, by using a fully objective association design, that differences among Y chromosomes contribute to variation in vulnerability to alcohol dependence. However, they do not demonstrate an association between Y haplotype and the personality variables thought to underlie the subtypes of alcoholism.

    Background 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. Methods 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. Findings 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. Conclusions 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.

    Full Text Available Abstract Background In France outpatient centres for the care of alcoholics are healthcare establishments providing medical, psychological and social support. Although they meet the practical needs of these patients, their degree of use in each of these domains and the respective mobilisation of different skills by the care team are not well understood. Our aim was therefore to determine in detail the management involved as a function of the severity of alcohol dependence. For this purpose, all the procedures involved were compiled in a thesaurus describing its type (psychological, medical, social, reception, its scheduled or unscheduled nature, its method (face-to-face, telephone, letter and its duration. The severity of dependence was evaluated using the Addiction Severity Index (ASI. Results 45 patients were included and followed-up during 291 ± 114 days. The mean initial ASI scores (± SD were: medical (M = 0.39 ± 0.3, working-income (ER = 0.5 ± 0.3, alcohol (A = 0.51 ± 0.2, illicit drugs (D = 0.07 ± 0.08, legal (L = 0.06 ± 0.13, familial and social environment (FS = 0.34 ± 0.26, psychological (P = 0.39 ± 0.22. The total number of procedures was 1341 (29.8 per patient corresponding to 754.4 hours (16.7 per patient. The intensity of management peaked during the first month of treatment, and then declined rapidly; the maximum incidence of abstinence was observed during the 3rd month of management. Interviews with patients, group therapy and staff meetings represented 68.7%, 9.9% and 13.9% of all procedures, respectively. In patients with severe dependence, as compared to moderate, management was twice as intense in the psychological and social domains, but not in the medical domain. The ASI questionnaire was completed a second time by 24 patients, after an average of 3.2 months. The improvement was significant in the M, A, D and P domains only. Conclusion This study provided an overview of the methods employed in managing a sample of

Materials and Methods: The study was conducted in De-Addiction Clinic of the Department of Psychiatry, Mamata Medical College, Khammam, Andhra Pradesh from July 2008 to February 2009. Patient who fulfills criteria for alcohol dependence, according to diagnostic and statistical manual of mental disorders, fourth edition were included. Results: Mean age (standard deviation at first drink was 18.93 (3.81 years and at onset of Alcohol dependence was 28.28 (6.55 years. The most common reason being given by the patients was financial strain (70% of the patients due to alcohol use and its consequences. Educational qualification of 12th standard or above was seen only in 7.5%. Alcohol dependence syndrome was more common in unemployed, unskilled and semi-skilled patients. Majority of patients (80% belonged to lower socio-economic class. Conclusion: Alcohol dependence syndrome and its related co morbidities can be minimized to a great extent if the educational and socio-economic standards are improved in countries like India where there is increase in alcohol consumption as a life style choice.

    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 (=18) and alcohol-dependents (=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.

    Full Text Available ABSTRACT Objectives High rates of comorbidity between social anxiety disorder (SAD and alcohol use disorders have been reported, but the predictors of this comorbidity are poorly known and most studies involve primary SAD samples. The aims were to estimate the prevalence and severity of SAD symptoms among alcohol-dependent patients and to investigate sociodemographic and clinical factors associated with SAD comorbidity, including suicidal behaviors. Methods A cross-sectional study with 53 adults who were in treatment for alcohol dependence at a Brazilian public university outpatient service. Assessment instruments Social Phobia Inventory (SPIN, Short Alcohol Dependence Data and Beck Depression Inventory. Bivariate analyses between the categorical outcome (Probable SAD: SPIN ≥ 19 and explanatory variables were conducted. Correlates of SPIN total and subscales scores (dimensional outcomes were also investigated. Results The diagnosis and treatment of alcohol dependence occurred, on average, 30 years after the onset of alcohol use and 39.6% of the 53 patients (37 men and 16 women reported alleviation of social anxiety symptoms with alcohol use. Twenty-four (45.3% patients presented probable SAD. These patients differed from non-SAD alcohol-dependent individuals by having lower income and higher frequency of depression, suicidal ideation, suicide plans and attempts. The SPIN subscales mostly associated with suicidal behaviors were social inadequacy and social inferiority. Conclusions SAD symptoms are common among help-seeking alcohol-dependent individuals and should be directly investigated and treated, since depression and suicidality are associated with this comorbidity. Prospective studies are needed to assess the impact of SAD treatment on the clinical course of alcohol dependence.

The present research aimed to study the prevalence of MS and its correlates among the alcohol-dependent men at a deaddiction center in Northern India. Materials and Methods: A cross-sectional analysis was done for consecutive male subjects who met the diagnosis of alcohol-dependence syndrome currently using alcohol according to the International Clinical Diagnostic criteria- tenth revision mental and behavioral disorder- Clinical description and diagnostic guidelines criteria (ICD-10. The subjects were evaluated for alcohol consumption and the components of MS as per the International Diabetic Federation (IDF and National Cholesterol Education Program Adult Treatment Panel-III (NCEP ATP-III. Results: A total of 200 male subjects were studied: 100 subjects meeting ICD-10 criteria for alcohol dependence currently using alcohol; 50 each of genetically related controls and nongenetically related healthy controls. As per the IDF (with ethnicity specific modifications for waist circumference and NCEP ATP- III definitions, respectively, MS was found to be less prevalent in alcohol-dependent subjects (27% and 18% in comparison the healthy controls (30% and 20%. Conclusion: Findings of the study suggest that irrespective of the amount the current alcohol intake is associated with a lower prevalence of MS and a favorable effect on serum high density lipoproteins and waist circumference. However, the cross-sectional nature of our study does not allow any definitive causal inference.

    Chronic alcohol abuse has been traditionally associated with impaired cognitive abilities. The deficits are most evident in higher order cognitive functions, such as abstract reasoning, problem solving and visuospatial processing. The present study sought to increase current understanding of the neuropsychological basis of poor abstract reasoning abilities in alcohol-dependent subjects using functional magnetic resonance imaging (fMRI). An abstract reasoning task-based fMRI study was carried out on alcohol-dependent subjects (n = 18) and healthy controls (n = 18) to examine neural activation pattern. The study was carried out using a 3-T whole-body magnetic resonance scanner. Preprocessing and post processing was performed using SPM 8 software. Behavioral data indicated that alcohol-dependent subjects took more time than controls for performing the task but there was no significant difference in their response accuracy. Analysis of the fMRI data indicated that for solving abstract reasoning-based problems, alcohol-dependent subjects showed enhanced right frontoparietal neural activation involving inferior frontal gyrus, post central gyrus, superior parietal lobule, and occipito-temporal gyrus. The extensive activation observed in alcohol dependents as compared to controls suggests that alcohol dependents recruit additional brain areas to meet the behavioral demands for equivalent task performance. The results are consistent with previous fMRI studies suggesting decreased neural efficiency of relevant brain networks or compensatory mechanisms for the execution of task for showing an equivalent performance.

    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.

    Heart rate variability (HRV) is an objective and sensitive measure of integrated physiological functioning reflective of heart rhythm responsivity to internal and external demands. Reduced HRV is associated with vulnerability to stress and deterioration of medical and/or psychiatric conditions, while increased HRV is associated with a favorable treatment response and recovery from various medical and/or psychiatric conditions. Our previous review found that acute alcohol consumption caused decreased parasympathetic and increased sympathetic HRV effects in both nonalcoholic and chronic alcohol users. This review investigates the effects of chronic alcohol consumption on HRV in alcohol-dependent subjects and nondependent users. MEDLINE, Scopus, and PubMed were searched for human experimental and clinical trials that measured the effects of chronic alcohol use on HRV. Only publications that included a description of their study designs and clearly stated methodologies for data collections, and outcome measures were reviewed. We have reviewed a total of 24 articles. In nondependent users, low dose (approximating the recommended daily amount of 1 standard drink in women and 2 in men) use is associated with increased HRV parameters compared to those who drink less frequently or abstain altogether. A further increase in consumption is associated with decreased HRV compared to both abstainers and more moderate drinkers. HRV changes during withdrawal generally follow the same negative direction but are more complex and less understood. In dependent subjects, an improvement in HRV was seen following abstinence but remained reduced compared to nonalcoholic controls. This review demonstrates that HRV changes associated with chronic use follow a J-shaped curve. It supports recommendations that limit daily alcohol intake to no more than 2 drinks for men and 1 drink for women. Future studies should investigate HRV as a biomarker of alcoholism development and treatment response as

    Full Text Available There are limited numbers of studies which have evaluated the sexual dysfunction (SD in patients with alcohol and opioids dependence. This article reviews the existing literature. Electronic searches were carried out using the PubMed, Google Scholar, and ScienceDirect to locate the relevant literature. Subjects addicted to heroin or on methadone maintenance treatment (MMT or buprenorphine maintenance treatment (BMT show higher rates of SD in comparison to the general population. SD rates have ranged 34-85% for heroin addicts, 14-81% for MMT, 36-83% for BMT, and 90% for naltrexone maintenance. The rates of SD in alcohol-dependent population have ranged 40-95.2%, with rates being consistently much higher in alcohol-dependent population than in the healthy controls or social drinkers. The common SDs reported have been erectile dysfunction followed by premature ejaculation, retarded ejaculation and decreased sexual desire among men, and dyspareunia and vaginal dryness among women. This review suggests that long-term use of alcohol and opioids are associated with SD in almost all domains of sexual functioning. There is a need to increase the awareness of clinicians about this association as many times SD in patients with substance abuse lead to poor treatment compliance and relapse. Further, there is a need to carry out more number of studies to understand the relationship in a better way.

    Karina Łukasik

    2010-10-01

    Full Text Available The lack of satisfactory results of alcohol dependence treatment has necessitated the search for new directions of studies. One of them is connected with glutamatergic transmission. The influence of alcohol on this transmission is very complex and relates to changes including at the molecular level. However, the diversity of glutamatergic receptors creates a new possibility of modulation of its activity. It leads to decrease of alcohol reward abilities, prolongs abstinence time and reduces the incidence of acute alcohol intoxication in alcohol addicts. The use of acamprosate – a glutamatergic transmission modulator drug – and naltrexone (an opioid receptor antagonist improves therapy effectiveness of acamprosate alone. Satisfactory results were achieved in the studies of topiramate – an antagonist of AMPA and KA receptors. Its effectiveness was proved in clinical studies. Topiramate reduced alcohol craving and prolonged abstinence time, which decreased the probability of relapse. There are promising preclinical results of groups I and II metabotropic receptor antagonists. However, further studies are necessary to elucidate precisely their role in alcohol dependence.

    Background 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. Methods 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. Results 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. Conclusions These findings suggest that chronic alcohol dependence could cause a complex neural changes linked to abnormal impulsivity. PMID:27575491

    2013-09-01

    Alcohol dependence is a severe, chronic illness. Even the best-assessed drugs used to maintain abstinence are poorly effective. Some patients remain dependent after several treatment attempts. Baclofen has been tested for its capacity to reduce craving for alcohol. We reviewed the data available as of early 2013, using the standard Prescrire methodology, in order to assess the harm-benefit balance of baclofen in maintaining abstinence or moderation in alcohol-dependent patients. Two double-blind, randomised, placebo-controlled trials conducted by the same team tested baclofen 30 mg/day in 123 alcohol-dependent patients referred to alcohol treatment centres. After 1 or 3 months of followup, more patients remained abstinent in the baclofen group than in the placebo group. In another double-blind, randomised trial, baclofen 30 mg/day was not more effective than placebo in 80 alcohol-dependent patients recruited through advertisements, many of whom were seeking treatment for the first time. Three uncontrolled retrospective series reported the results obtained in 300 alcohol-dependent patients, most of whom were in treatment failure. They were treated with high, escalating doses of baclofen (on average about 150 mg per day, up to 400 mg per day) with the intention of reducing their craving for alcohol. After 3 to 24 months of follow-up, about half of the patients reported moderate or zero alcohol consumption. At moderate doses, baclofen has been used since the 1970s in the treatment of certain forms of muscle spasticity. The main adverse effects reported in this setting were drowsiness (especially early during treatment) and various neuropsychiatric disorders such as dizziness, euphoria, depression, headache, paraesthesias, speech disorders, ataxia and insomnia. The adverse effects of high-dose baclofen are mainly based on monitoring of hundreds of alcohol-dependent patients, 69 reports to French pharmacovigilance centres in 2011, and cases of overdose or accidental

    Full Text Available Background: Treatment of postabstinence syndrome of alcohol is one of the major strategies of alcoholism treatment. Exercise can be modulated major brain pathways such as a reward system and pain perception centers. The aim of this study was to evaluation the effects of forced exercise in the management of alcohol dependence and pain perception alteration which induced by alcoholism. Methods: 72 adult male rats were divided into 2 major groups: (1 40 of them was divided into groups of positive control (alcohol dependent negative control and alcohol dependent groups under treatment by forced exercise, diazepam (0.4 mg/kg and forced exercise in combination with diazepam and alcohol withdrawal signs, and blood cortisols, were measured in this groups. (2 32 rats were divided into control, alcohol dependent (without treatment, and alcohol-dependent groups under treatment by forced exercise or indometacin (5 mg/kg and then pain perception was assessed by using writhing test, tail-flick and hot plate test. Results: Forced exercise, diazepam, and their combinations significantly attenuates withdrawal syndrome to 20 ± 2, 22 ± 1.3 and 16 ± 2 and blood cortisol level to 6.8 ± 1.3,7.9 ± 1.2 and 5.8 ± 1.1, respectively, in comparison with the positive control group (P < 0.05 and P < 0.001. In alcohol dependent animal under treatment by forced exercise, pain response significantly inhibited with 37%, 57% and 38% decreases in writhing test, hot plate, and tail-flick test, respectively, in comparison with alcohol dependent (without treatment group (P < 0.05. Conclusions: This study suggested that forced exercise can be useful as adjunct therapy in alcoholism patient and also can be effective in modulation of pain threshold reduction that was induced by alcohol dependency.

    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 increase 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 of 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.

    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.

    The quinone-dependent alcohol dehydrogenase (PQQ-ADH, E.C. 1.1.5.2) from the Gram-negative bacterium Pseudogluconobacter saccharoketogenes IFO 14464 oxidizes primary alcohols (e.g. ethanol, butanol), secondary alcohols (monosaccharides), as well as aldehydes, polysaccharides, and cyclodextrins. The recombinant protein, expressed in Pichia pastoris, was crystallized, and three-dimensional (3D) structures of the native form, with PQQ and a Ca(2+) ion, and of the enzyme in complex with a Zn(2+) ion and a bound substrate mimic were determined at 1.72 Å and 1.84 Å resolution, respectively. PQQ-ADH displays an eight-bladed β-propeller fold, characteristic of Type I quinone-dependent methanol dehydrogenases. However, three of the four ligands of the Ca(2+) ion differ from those of related dehydrogenases and they come from different parts of the polypeptide chain. These differences result in a more open, easily accessible active site, which explains why PQQ-ADH can oxidize a broad range of substrates. The bound substrate mimic suggests Asp333 as the catalytic base. Remarkably, no vicinal disulfide bridge is present near the PQQ, which in other PQQ-dependent alcohol dehydrogenases has been proposed to be necessary for electron transfer. Instead an associated cytochrome c can approach the PQQ for direct electron transfer.

    This study investigates the associations of recent criminal justice involvement with perceived need for alcohol treatment and alcohol treatment utilization, adjusting for demographic and clinical characteristics. We examined a national sample of adults with alcohol use disorders (AUD, N=4,390) from the 2006 National Survey on Drug Use and Health (NSDUH). Almost 15% reported criminal justice involvement in the past year. Generalized logit models regressed perceived need for alcohol or drug treatment and past year treatment utilization (versus neither) on past year legal involvement, demographic, and clinical information. In general, results found stronger associations between frequency of criminal justice involvement for treatment utilization compared to perceived need for treatment alone. Treatment utilization was also associated with being on probation, arrests for drug possession/sale and DUI but perceived need was not. Study results suggest opportunities for interventions to increase treatment rates or treatment need, a major correlate of treatment utilization. PMID:22954511

    Salivary lactoferrin is a glycoprotein involved in the elimination of pathogens and the prevention of massive overgrowth of microorganisms that affect oral and general health. A high concentration of lactoferrin in saliva is often considered to be a marker of damage to the salivary glands, gingivitis, or leakage through inflamed or damaged oral mucosa, infiltrated particularly by neutrophils. We conducted a study to determine the effect of chronic alcohol intoxication on salivary lactoferrin concentration and output. The study included 30 volunteers consisting of ten non-smoking male patients after chronic alcohol intoxication (group A, and 20 control nonsmoking male social drinkers (group C with no history of alcohol abuse. Resting whole saliva was collected 24 to 48 hours after a chronic alcohol intoxication period. Lactoferrin was assessed by enzyme-linked immunosorbent assay. For all participants, the DMFT index (decayed, missing, or filled teeth, gingival index (GI and papilla bleeding index (PBI were assessed. The differences between groups were evaluated using the Mann–Whitney U test. We noticed significantly decreased salivary flow (SF in alcohol dependent patients after chronic alcohol intoxication (A, compared to the control group (C. Although there was no significant difference in salivary lactoferrin concentration between the alcohol dependent group A and the control group C, we found significantly decreased lactoferrin output in group A compared to group C. We found a significant correlation between the amount of daily alcohol use and a decrease in lactoferrin output. There was a significant increase in GI and a tendency of PBI to increase in group A compared to group C. We demonstrated that chronic alcohol intoxication decreases SF and lactoferrin output. The decreased lactoferrin output in persons chronically intoxicated by alcohol may be the result of lactoferrin exhaustion during drinking (due to its alcohol-related lower

    Full Text Available Much of the evolution of human behavior remains a mystery, including how certain disadvantageous behaviors are so prevalent. Nicotine addiction is one such phenotype. Several loci have been implicated in nicotine related phenotypes including the nicotinic receptor gene clusters (CHRNs on chromosomes 8 and 15. Here we use 1000 Genomes sequence data from 3 populations (Africans, Asians and Europeans to examine whether natural selection has occurred at these loci. We used Tajima's D and the integrated haplotype score (iHS to test for evidence of natural selection. Our results provide evidence for strong selection in the nicotinic receptor gene cluster on chromosome 8, previously found to be significantly associated with both nicotine and cocaine dependence, as well as evidence selection acting on the region containing the CHRNA5 nicotinic receptor gene on chromosome 15, that is genome wide significant for risk for nicotine dependence. To examine the possibility that this selection is related to memory and learning, we utilized genetic data from the Collaborative Studies on the Genetics of Alcoholism (COGA to test variants within these regions with three tests of memory and learning, the Wechsler Adult Intelligence Scale (WAIS Block Design, WAIS Digit Symbol and WAIS Information tests. Of the 17 SNPs genotyped in COGA in this region, we find one significantly associated with WAIS digit symbol test results. This test captures aspects of reaction time and memory, suggesting that a phenotype relating to memory and learning may have been the driving force behind selection at these loci. This study could begin to explain why these seemingly deleterious SNPs are present at their current frequencies.

    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.

    A review of the literature pertinent to cue exposure treatment in alcohol dependence is presented. Psychological models of relapse, based on conditioning and social learning theories, are critically evaluated. In particular, attention is drawn to the potential implications for cue exposure research and treatment of an interaction between Pavlovian and operant conditioning, problems with the application of the concepts of arousal and craving and the importance of a systems model to understand physiological responses. It is concluded that no study has so far demonstrated a link between conditioned responses to alcohol-related cues and relapse, an assumption on which cue exposure treatment is based. Further, the evidence for the effectiveness of cue exposure as a treatment is lacking. Promising research directions are identified.

    2011-01-01

    Emerging evidence indicates that ethanol-induced alterations in hepatic methionine metabolism play a central role in the pathogenesis of alcoholic liver disease (ALD). Because malnutrition is a universal clinical finding in this disease and hepatic methionine metabolism is dependent upon dietary folate and vitamins B-6 and B-12, ALD can be considered an induced nutritional disorder that is conditioned by alcohol abuse. The present review describes the etiologies of these 3 vitamin deficiencies in ALD and how they interact with chronic ethanol exposure to alter hepatic methionine metabolism. Subsequent sections focus on molecular mechanisms for the interactions of aberrant methionine metabolism with ethanol in the pathogenesis of ALD, in particular the role of S-adenosylmethionine (SAM) in regulating the epigenetic expressions of genes relevant to pathways of liver injury. The review will conclude with descriptions of studies on the efficacy of SAM in the treatment of ALD and with discussion of potentially fruitful future avenues of research. PMID:22332083

    Chronic intermittent alcohol (CIA) exposure produces altered motivational states characterized by anxiety and escalated alcohol consumption during withdrawal. The endocannabinoid (ECB) system contributes to these symptoms, and sex differences in alcohol dependence, as well as bidirectional interactions between ECBs and gonadal hormones have been documented. Thus, we evaluated sex differences in alcohol consumption, anxiety-like behavior, and ECB mRNA expression in the nucleus accumbens (NAc) of alcohol-dependent rats during acute withdrawal. Male rats exposed to six weeks of CIA showed escalated alcohol consumption during acute withdrawal and reductions in NAc N-acyl phosphatidylethanolamine phospholipase D (NAPEPLD), DAG lipase alpha (DAGLα), and monoacylglycerol lipase (MAGL) mRNA. Intact alcohol-dependent female rats also escalated their consumption, but notably, this effect was also present in non-dependent females. No differences in NAc ECB mRNA were observed between CIA- and air-exposed females during acute withdrawal. However, when these data were analyzed according to estrous stage, significant differences in NAPEPLD and MAGL mRNA expression emerged in the NAc of air-exposed control rats, which were absent in alcohol-dependent females. We subsequently measured alcohol consumption and NAc ECB mRNA in ovariectomized (OVX) females with or without estradiol (E2) replacement during withdrawal. Neither E2 nor CIA altered alcohol consumption in OVX females. However, E2 reduced both DAGLα and MAGL mRNA, suggesting that E2 may influence the biosynthesis and degradation of 2-arachidonoylglycerol (2-AG) in the NAc. Collectively, these studies indicate sexual dimorphism in alcohol consumption in non-dependent rats and suggest that E2-mediated alterations in NAc ECB mRNA expression during withdrawal may be a mechanism by which sex differences in alcohol dependence emerge.

    Full Text Available Abstract Background Several studies have indicated that early emotional traumas (EET are highly prevalent in alcohol-dependent individuals, and that these traumas work as risk factors for the development of this disorder. Objective The aim of the current study is to evaluate the EET associations and predictive value regarding active alcohol dependence among male individuals from a developing country. Methods The sample consisted of two groups. The first was composed by adult male individuals diagnosed as alcohol dependents (AG, N = 110, and the second with no alcohol abuse and/or dependence diagnosis (CG, N = 110. Both groups were evaluated using Structured Clinical Interview based on the Diagnostic and Statistical Manual of Mental Disorders; Early Emotional Trauma Inventory; and a sociodemographic questionnaire. Results All trauma subtypes (general, physical, emotional and sexual were more prevalent among AG than CG. However, only traumas categorized as general and emotional worked as risk factor for alcoholism development and they increased the chances to develop this disorder by 1.45 and 1.23 times, respectively. Discussion EETs are important factors that should be taken into account in interventions that aim to prevent, minimize and/or treat this clinical condition and its impact and/or severity, especially in countries such as Brazil.

    Full Text Available Although there are numerous ideas on the management of alcohol dependence, ranging from various schemes of pharmacologic treatment to specific psychotherapeutic approaches, the reviews and meta-analyses reveal only modest effects of these approaches. Another approach regarding the problem of alcohol is based on the behavioral biology, specifying that consumption of alcohol is actually a type of behavior, a way of life. The results presented in this report provide evidence to support the idea that the systemic, ethological approach of alcohol-related and complex problems brings additional value when complementing the standard medicinal therapy, both in terms of achieving and maintaining abstinence, as well as in improving the quality of life for the patients.

  7. Are the effects of gamma-hydroxybutyrate (GHB) treatment partly physiological in alcohol dependence?

    Science.gov (United States)

    Ameisen, Olivier

    2008-01-01

    It has been hypothesized that the therapeutic effects of Gamma-hydroxybutyrate (GHB) in alcohol dependence could be related to ethanol-mimicking action of the drug and that GHB could reduce alcohol craving, intake and withdrawal by acting as a "substitute" of the alcohol in the central nervous system. Nevertheless, alcohol being the strongest trigger of craving and intake, it is difficult to ascribe reduction of craving and intake to ethanol-mimicking activity of GHB. I have recently proposed that alcohol/substance dependence could result from a GHB-deficiency-related dysphoric syndrome in which alcohol/substances would be sought to "substitute" for insufficient GHB effect. GHB is the sole identified naturally occurring gamma-aminobutyric acid B (GABA (B)) receptor agonist. Here, I propose that exogenous GHB might in fact "substitute" for deficient endogeneous GHB and represent true substitutive treatment for GHB-deficiency. And that baclofen and GHB could both compensate for deficient effect of the physiological GABA (B) receptor agonist(s).

    Full Text Available Alcohol use disorder (AUD is a worldwide public health problem and a polygenetic disorder displaying substantial individual variation. This work aimed to study individual differences in behavior and its association to voluntary alcohol intake and subsequent response to naltrexone in a seamless heterogenic group of animals. Thus, by this approach the aim was to more accurately recapitulate the existing heterogeneity within the human population. Male Wistar rats from three different suppliers (Harlan Laboratories B.V., RccHanTM:WI; Taconic Farms A/S, HanTac:WH; and Charles River GmbH, Crl:WI were used to create a heterogenic group for studies of individual differences in behavior, associations to intermittent voluntary alcohol intake and subsequent response to naltrexone. The rats were tested in the open field prior to the Y-maze and then given voluntary intermittent access to alcohol or water in the home cage for six weeks, where after, naltrexone in three different doses or saline was administered in a Latin square design over four weeks and alcohol intake and preference was measured. However, supplier-dependent differences and concomitant skew subgroup formations, primarily in open field behavior and intermittent alcohol intake, resulted in a shifted focus to instead study voluntary alcohol intake and preference, and the ensuing response to naltrexone in Wistar rats from three different suppliers. The results showed that outbred Wistar rats are diverse with regard to voluntary alcohol intake and preference in a supplier-dependent manner; higher in RccHanTM:WI relative to HanTac:WH and Crl:WI. The results also revealed supplier-dependent differences in the effect of naltrexone that were dose- and time-dependent; evident differences in high-drinking RccHanTM:WI rats relative to HanTac:WH and Crl:WI rats. Overall these findings render RccHanTM:WI rats more suitable for studies of individual differences in voluntary alcohol intake and response to

Neuropsychological functions in these children have been the focus of attention over the last decade. AIM: Aim of this study was to compare the nature and extent of behavioral and cognitive problems in children of men with and without alcohol dependence. MATERIALS AND METHODS: Children of patients with Alcohol Dependence Syndrome, with no known psychiatric illness; aged between 5 and 10 years (B oth male & female; with mother having GHQ scores less than 4, formed the study group and control group formed by the children of normal. 108 such Children (54 in Study group and 54 in Control group were evaluated for psychopathology, neuro development and cognitive functioning. Tools used were: DSM IV criteria for diagnosis of Alcohol Dependence Syndrome, Severity of Alcohol Dependence Questionnaire, General Health Questionnaire (GHQ - 28, and Socio - demographic data sheet, Child Behavior Checklist (CBCL, Wechsler Intelligence Scale for Children – IV (WISC - IV, Trail Making Test (TMT and Neurodevelopment Scale. RESULTS: Behavioral, emotional difficulties and Neuro developmental deficits are commonly seen in children of alcohol - dependent parents as they scored statistically significant high scores on Neurodevelopmental Scale, Externalizing subscale and a marginal high score on Internalizing Subscale of CBCL. On the WISC - IV , there was a statistically significant difference in various subtests and indices including verbal comprehension, perceptual reasoning, working memory, processing speed and total intellectual quotient ; indicating a global dysfunction. On the TMT, children of alcohol - dependent parents took as much time to do the task as the control group but tended to make more errors and this difference is

    Full Text Available Background: Use of tobacco among alcohol dependent population is quite frequent. This co-morbidity increases the risk for various diseases. Understanding the pattern of tobacco use with co-morbid alcohol use may help in planning appropriate prevention/treatment strategies. The study aimed at examining the profile and pattern of nicotine use among alcohol dependent patients visiting a tertiary care treatment center in North India. Materials and Methods: Male patients fulfilling diagnostics and statistical manual of mental disorder fourth edition, criteria for nicotine and alcohol diagnostics and statistical dependence, attending the out-patient department of the tertiary care treatment center were recruited after obtaining informed consent. The socio-demographic profile, drug use history, nicotine associated health problems and general health problem were recorded. Motivation to stop tobacco use was assessed qualitatively using the direct questions about their interest and intentions to quit. Results: A total of 150 subjects were included in the study. The mean age of the study sample was 37.6 ± 10.44 years. Tobacco was reported as the gateway drug in 90% of the cases. Exclusive bidi use reported in 42% of the subjects. Mean duration of bidi and co-morbid alcohol use was higher than cigarette or smokeless tobacco use. Self-reported health problems associated with nicotine use and general health was reported by 41% and 39% of the subjects. Unsuccessful past quit attempts was present in 85% cases. More than 90% of subjects remained interested in quitting the tobacco use. An increased liver enzyme (aspartate transaminase, alanine transaminase and gamma-glutamyl transferase were observed in 43, 32 and 47% of the cases. Conclusion: The results suggest the nicotine and alcohol dependent patients represent a separate population requiring higher attention from the treating physician.

    Full Text Available Abstract Background Evidence for a high degree of heritability of EEG alpha phenotypes has been demonstrated in twin and family studies in a number of populations. However, information on linkage of this phenotype to specific chromosome locations is still limited. This study's aims were to map loci linked to EEG alpha phenotypes and to determine if there was overlap with loci previously mapped for alcohol dependence in an American Indian community at high risk for substance dependence. Methods Each participant gave a blood sample and completed a structured diagnostic interview using the Semi Structured Assessment for the Genetics of Alcoholism. Bipolar EEGs were collected and spectral power determined in the alpha (7.5-12.0 Hz frequency band for two composite scalp locations previously identified by principal components analyses (bilateral fronto-central and bilateral centro-parietal-occipital. Genotypes were determined for a panel of 791 micro-satellite polymorphisms in 410 members of multiplex families using SOLAR. Results Sixty percent of this study population had a lifetime diagnosis of alcohol dependence. Analyses of multipoint variance component LOD scores, for the EEG alpha power phenotype, revealed two loci that had a LOD score of 3.0 or above for the fronto-central scalp region on chromosomes 1 and 6. Additionally, 4 locations were identified with LOD scores above 2.0 on chromosomes 4, 11, 14, 16 for the fronto-central location and one on chromosome 2 for the centro-parietal-occipital location. Conclusion These results corroborate the importance of regions on chromosome 4 and 6 highlighted in prior segregation studies in this and other populations for alcohol dependence-related phenotypes, as well as other areas that overlap with other substance dependence phenotypes identified in previous linkage studies in other populations. These studies additionally support the construct that EEG alpha recorded from fronto-central scalp areas may

    Full Text Available Abstract Background We carried out a three months follow-up study on the efficacy of metadoxine in a cohort of alcoholics admitted to the Alcohol misuse Long-term Treatment (ALT Unit – University of Pisa (Italy. We analyzed the clinical data, psychometric tests and blood tests of 160 alcoholics on admission and after 3 months of treatment. We compared 58 pts treated with metadoxine (MET with 102 pts who did not receive (NULL any drug as an adjunct to the psycho-educational interventions provided by the ALT Unit. Results At follow-up, the patients in treatment with metadoxine showed a significant improvement in the rate of complete abstinence (44.8% vs. 21.6%; chi square: 8.45, df = 1, p Conclusion Our findings support the use of metadoxine in the management of alcohol dependence. However, randomized clinical trials are necessary to confirm and replicate them. This study raises the importance of identifying new pharmacological compounds effective on the outcome of alcoholism in order to help patients to best adhere to treatment programs and to prevent the development of mental and physical complications due to chronic and heavy use of alcohol.

    Background: The genes coding for ethanol metabolism enzymes [alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH)] have been widely studied for their influence on the risk to develop alcohol dependence (AD). However, the relation between polymorphisms of these metabolism genes and AD in Caucasian subjects has not been clearly established. The present study examined evidence for the association of alcohol metabolism genes with AD in the Irish Affected Sib Pair Study of alcohol dependence. Methods: We conducted a case–control association study with 575 independent subjects who met Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, AD diagnosis and 530 controls. A total of 77 single nucleotide polymorphisms (SNPs) in the seven ADH (ADH1-7) and two ALDH genes (ALDH1A1 and ALDH2) were genotyped using the Illumina GoldenGate protocols. Several statistical procedures were implemented to control for false discoveries. Results: All markers with minor allele frequency greater than 0.01 were in Hardy–Weinberg equilibrium. Numerous SNPs in ADH genes showed association with AD, including one marker in the coding region of ADH1C (rs1693482 in exon6, Ile271Gln). Haplotypic association was observed in the ADH5 and ADH1C genes, and in a long haplotype block formed by the ADH1A and ADH1B loci. We detected two significant interactions between pairs of markers in intron 6 of ADH6 and intron 12 of ALDH2 (p = 5 × 10−5), and 5′ of both ADH4 and ADH1A (p = 2 × 10−4). Conclusion: We found evidence for the association of several ADH genes with AD in a sample of Western European origin. The significant interaction effects between markers in ADH and ALDH genes suggest possible epistatic roles between alcohol metabolic enzymes in the risk for AD. PMID:18331377

    The relationship between alcohol dependency and disorders such as liver disease and cancer has been thoroughly researched. However, the effects of alcohol on cardiometabolic health remain controversial. Several reports found low to moderate alcohol consumption to be associated with a lower risk for cardiometabolic disorders. In contrast, excessive alcohol consumption has been related to an increased risk. Most of these studies were performed in non-clinical populations, therefore limiting the explanatory power to non-dependent patients. Only a few studies examined cardiovascular disorders and cardiovascular risk factors, in particular the metabolic syndrome (MetS), in alcohol dependent patients. We here present a narrative review of studies performed so far on the MetS in alcohol dependency, and provide current hypotheses on the association of alcohol dependency, appetite regulation and the development of the MetS.

    2016-06-01

    Full Text Available BACKGROUND A potentially powerful predictor of progression to alcohol-related harm is age at first use. Evidence suggests that the earlier the age at which young people take their first drink of alcohol, the greater the risk of abusive consumption and the development of alcohol related disorders. Equally important is the family history of alcoholism, which is associated with early age of drinking. AIM This study specifically aims to explore the relationship between severity of alcohol dependence with family history of alcoholism and age of onset of alcohol use. MATERIALS AND METHODS For a period of six months, we conducted a cross sectional study among 200 male subjects aged between 20–50 years who reported the alcohol and drug dependence clinic of a tertiary care hospital in Chennai, Tamilnadu State with problem drinking in the past one year. We used Alcohol Use Disorder Identification Test (AUDIT, Clinical Institute Withdrawal Assessment for Alcohol (CIWA-AD, Severity of Alcohol Dependence Questionnaire (SADQ, Family History Method, and Schedule for Clinical Assessment in Neuropsychiatry (SCAN for assessment. 123 subjects were Family History Positive (FHP and 77 were family history negative (FHN. The data was analysed using a computerized Statistical Software programme (SPSS version 20.0 for windows. Descriptive statistics was used to describe the socio-demographic variables. Student t-test was used to compare between ordinal groups. Pearson’s correlation was used for assessing the correlation between the variables. RESULTS The mean severity scores were significantly different between the early age of onset and late age of onset groups. The mean current age in the FHP was 38.61±8.59 and 42.12±6.90 in FHN. The Mean AOO in the FHP was 22.89±4.61 and in the FHN was 26.51±26.51 and was significantly different from each other (P<0.000. The Mean SADQ score were 44.59±10.79 in FHP and 38.96±11.50 in the FHN.

    Previous studies have shown associations between SNPs in GABRA2 and adolescent conduct disorder (CD) and alcohol dependence in adulthood, but not adolescent alcohol dependence. The present study was intended as a replication and extension of this work, focusing on adolescent CD, adolescent alcohol abuse and dependence (AAD), and adult AAD. Family based association tests were run using Hispanics and non-Hispanic European American subjects from two independent longitudinal samples. Although the analysis provided nominal support for an association with rs9291283 and AAD in adulthood and CD in adolescence, the current study failed to replicate previous associations between two well replicated GABRA2 NPs and CD and alcohol dependence. Overall, these results emphasize the utility of including an independent replication sample in the study design, so that the results from an individual sample can be weighted in the context of its reproducibility.

    The aim of this study was to analyse the occurrence of alcohol dependence and abuse in relation to variables reflecting social network and leisure time, social class, education, occupation and family conditions. The study was based on the second wave of interviews performed within the longitudinal study of Women and Alcohol in Göteborg. In this present study we analysed 416 face-to-face interviews performed in 1995 96. Women with only one or no friends for support had higher rates of alcohol dependence and abuse than did women with more friends. Women with high rates of alcohol dependence or abuse did not take part in cultural events as much as women with low rates of alcohol dependence and abuse. Women with homemaking skills and gardening as leisure time interests had lower prevalences of alcohol dependence and abuse. In general, women with diagnoses of alcohol dependence and abuse in this population-based sample were not alone and without a social network. However, their pattern of activity differed slightly from those without such diagnoses. The association between women with alcohol dependence and abuse and leisure time activities is probably circular: a poor social network and low participation in social activities increase the risk of alcohol dependence and abuse, and alcohol dependence and abuse lead to low participation in social activities.

    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.

It is known that nerve-growth factor (NGF, one of the neurotrophins, is related to the growth and differentiation of nerve cells, as well as to a decline in cognitive function. The purpose of this study was to investigate the relationship between decreased NGF levels and cognitive decline in alcohol-dependent patients. The serum concentration of NGF was measured in 38 patients with chronic alcohol dependence, and several neuropsychological tests were also performed for cognitive function assessment. The results indicated a significant correlation between serum NGF level and the trail-making test part B, which evaluates executive function, but did not show a significant correlation with other cognitive function tests. An increased serum level of NGF was associated with a decreased completion time in the trail-making test B, and this finding indicates that a high serum level of NGF is related to greater executive function. This finding may imply a protective role of NGF in preventing neuron damage among patients with alcohol dependence. Larger controlled studies will be necessary in the future to investigate this issue further. Keywords: nerve-growth factor, alcohol dependence, executive function, trail-making test

    Full Text Available Abstract Background Despite the importance of heavy drinking and alcohol dependence among patients with opiate and cocaine dependence, few studies have evaluated specific interventions within this group. The aim of the present study was to evaluate the impact of screening with the Alcohol Use Disorders Identification Test (AUDIT and of brief intervention (BI on alcohol use in a sample of patients treated for opioid or cocaine dependence in a specialized outpatient clinic. Methods Adult outpatients treated for opioid or cocaine dependence in Switzerland were screened for excessive alcohol drinking and dependence with the AUDIT. Patients with AUDIT scores that indicated excessive drinking or dependence were randomized into two groups--treatment as usual or treatment as usual together with BI--and assessed at 3 months and 9 months. Results Findings revealed a high rate (44% of problematic alcohol use (excessive drinking and dependence among patients with opiate and cocaine dependence. The number of drinks per week decreased significantly between T0 (inclusion and T3 (month 3. A decrease in average AUDIT scores was observed between T0 and T3 and between T0 and T9 (month 9. No statistically significant difference between treatment groups was observed. Conclusions In a substance abuse specialized setting, screening for alcohol use with the AUDIT, followed by feedback on the score, and use of alcohol BI are both possibly useful strategies to induce changes in problematic alcohol use. Definitive conclusions cannot, however, be drawn from the study because of limitations such as lack of a naturalistic group. An important result of the study is the excellent internal consistency of AUDIT in a population treated for opiate or cocaine dependence.

    Full Text Available Background: Alcohol dependents have high percentage of nonfatal suicidal behaviors. There is no substantial data on anger and personality correlates of suicidal behaviors among alcohol users. The present work explored the relationship of anger and personality with suicidal behaviors among alcohol-dependent individuals. Materials and Methods: Sociodemographic data sheet, State Trait Anger Expression Inventory (STAXI, and Neo Five-Factor Inventory (NFFI were administered on 30 subjects who had lifetime history of suicidal attempt. Results: A total of 80% attempted suicide in the intoxicated states, 56.7% were high on trait anger, and 60% were high on anger expression outward. A significant negative correlation was found between expressing feelings (verbally/physically openness, conscientiousness, and agreeableness. A significant positive correlation was found between anger expression inward and neuroticism. Conclusions: It helped in understanding the psychological variables associated with suicidal behavior among alcohol-dependent individuals and has implications for addressing neuroticism openness, conscientiousness, and agreeableness for bringing change in anger expression.

    Full Text Available Background Both alcohol and other substances are utilized for emotional and cognitive regulation. Objectives The purpose of the present study was to compare metacognitive styles and distress intolerance in patients with alcohol and other substance dependence. Patients and Methods According to DSM-IV TR criteria, 45 patients with alcohol dependence (AD, 44 patients with substance dependence (SD, and 43 volunteers without AD or SD (control group were enrolled. Socio-demographic information form, Distress Tolerance Scale (DTS, and metacognitive questionaire-30 (MCQ-30 were used to evaluate the participants. Results Patients with AD had significantly lower “tolerance” subscale and total DTS scores than those with SD and control group(P = 0.008 for SD sample and P = 0.004 for control group. Patients with SD had significantly higher scores in “appraisal” subscale DTS than control group (P = 0.005. Patients of both AD and SD groups had significantly higher scores in “positive beliefs” subscale of MCQ-30 than control group (P = 0.012 for AD group and P = 0. 001 for SD group. There was no significant difference between AD and SD groups in any MCQ-30 subscale and total scores (P = 0.440. Conclusions Metacognitive regulation strategies are more considerable prediction than emotional regulation strategies in SD group than in AD group. Individuals with AD use alcohol as a means of both cognitive and emotional regulation strategy.

This AB can be evaluated by the alcohol Stroop test (AST. The AST is a modified Stroop task in which participants have to name the color of an alcohol-related word or a neutral word. AB is the response-time difference between these two types of words. The goal of the current study was to examine modification of AB during specialized hospitalization for alcohol dependence, with the suppression of a training bias that could be present in within-subject design. Methods: Individuals with alcohol-dependence disorders (Diagnostic and Statistical Manual of Mental Disorders, 4th edition and admitted for withdrawal in the addiction unit of the University Hospital of Clermont-Ferrand (test group, n = 42 and persons with no alcohol or psychiatric disorder (control group, n = 16, recruited among colleagues and friends of the staff, performed the AST. A subgroup of the test group performed the AST in admission (admission group, n = 19, and another subgroup undertook the test immediately before discharge (discharge group, n = 23. Results: Results showed an AB only for patients seen at admission (F[1,55] = 3.283, P = 0.075. Moreover, we observed that the AB in the admission group (mean = 34 ms, standard deviation [SD] = 70.06 was greater than the AB in the control group (mean = 23 ms, SD = 93.42, itself greater than the AB in the discharge group (mean = −12 ms, SD = 93.55 (t[55] = −1.71; P = 0.09.

    Eighty-two hospitalized alcoholics receiving pharmacological aversion therapy (PAT) over a 10-day treatment interval completed cognitive, behavioral, and psychophysiological measures evaluating conditioned aversion to alcohol. Pre-post assessments provided convergent support for the efficacy of PAT vis-à-vis production of conditioned aversion to alcohol. Positive alcohol-related outcome expectancies were significantly reduced, whereas confidence that drinking could be avoided in various high-risk situations for consumption was increased following PAT. Behavioral and cardiac rate assessments revealed significant changes following PAT that were specific to alcoholic beverages and potentially reflective of conditioned alcohol aversion. Patients with more extensive pretreatment experiences with alcohol-associated nausea and greater involvement in antisocial conduct appeared to be less susceptible to the PAT conditioning protocol.

The CV results provided Tafel slopes for alcohols in the range of 200-400 mV dec-1 which indicated a difference in the rate determining step. The decrease in Tafel slope was only observed in the case of methanol for the Ru-modified Pt electrode. This indicates that Ru improves the rate of determining step for methanol while hindering it for the other alcohols. The electrochemical impedance spectroscopy was also used to evaluate the electro-oxidation mechanism of alcohols on these electrodes. The simulated EIS results provided two important parameters: charge transfer resistance () and inductance (). The $R^{-1}_{ct}$ and -1 represent the rate of alcohol electro-oxidation and rate of desorption of intermediate species, respectively. These values increased with the increasing of temperature. The results from two techniques were well agreed that the electro-oxidation of methanol was improved by raising the temperature and ruthenium modification.

    Full Text Available Internet addiction disorder (IAD should belong to a kind of behavioral addiction. Previous studies indicated that there are many similarities in the neurobiology of behavior and substance addictions. Up to date, although individuals with IAD have difficulty suppressing their excessive online behaviors in real life, little is known about the patho-physiological and cognitive mechanisms responsible for IAD. Neuropsychological test studies have contributed significantly to our understanding of the effect of IAD on the cognitive function. The purpose of the present study was to examine whether Internet addictive individuals share impulsivity and executive dysfunction with alcohol-dependent individuals. Participants include 22 Internet addictive individuals, 22 alcohol-dependent patients (AD and 22 normal controls (NC. All participants were measured with BIS- 11, go/no-go task, WCST and Digit span task under the same experimental condition. Results showed that BIS-11 scores, false alarm rate, the total response errors, perseverative errors, failure to maintain set of IAD and AD group were significantly higher than that of NC group, and hit rate, percentage of conceptual level responses, the number of categories completed, forwards scores and backwards scores of IAD and AD group were significantly lower than that of NC group, however, no differences in above variables between IAD group and AD group were observed. These results revealed that the existence of impulsivity, deficiencies in executive function and working memory in an IAD and an AD sample, namely, Internet addictive individuals share impulsivity and executive dysfunction with alcohol-dependent patients.

    Alcohol dependence (AD) is a complex disorder with environmental and genetic origins. The role of two genetic variants in ALDH2 and ADH1B in AD risk has been extensively investigated. This study tested for associations between nine polymorphisms in ALDH2 and 41 in the seven ADH genes, and alcohol-related flushing, alcohol use and dependence symptom scores in 4597 Australian twins. The vast majority (4296) had consumed alcohol in the previous year, with 547 meeting DSM-IIIR criteria for AD. There were study-wide significant associations (P < 2.3 × 10−4) between ADH1B-Arg48His (rs1229984) and flushing and consumption, but only nominally significant associations (P < 0.01) with dependence. Individuals carrying the rs1229984 G-allele (48Arg) reported a lower prevalence of flushing after alcohol (P = 8.2 × 10−7), consumed alcohol on more occasions (P = 2.7 × 10−6), had a higher maximum number of alcoholic drinks in a single day (P = 2.7 × 10−6) and a higher overall alcohol consumption (P = 8.9 × 10−8) in the previous year than those with the less common A-allele (48His). After controlling for rs1229984, an independent association was observed between rs1042026 (ADH1B) and alcohol intake (P = 4.7 × 10−5) and suggestive associations (P < 0.001) between alcohol consumption phenotypes and rs1693482 (ADH1C), rs1230165 (ADH5) and rs3762894 (ADH4). ALDH2 variation was not associated with flushing or alcohol consumption, but was weakly associated with AD measures. These results bridge the gap between DNA sequence variation and alcohol-related behavior, confirming that the ADH1B-Arg48His polymorphism affects both alcohol-related flushing in Europeans and alcohol intake. The absence of study-wide significant effects on AD results from the low P-value required when testing multiple single nucleotide polymorphisms and phenotypes. PMID:18996923

    A complex relationship exists between alcohol-drinking behavior and stress. Alcohol has anxiety-reducing properties and can relieve stress, while at the same time acting as a stressor and activating the body’s stress response systems. In particular, chronic alcohol exposure and withdrawal can profoundly disturb the function of the body’s neuroendocrine stress response system, the hypothalamic–pituitary–adrenocortical (HPA) axis. A hormone, corticotropin-releasing factor (CRF), which is produc...

    2011-07-01

    Based on Wells and Matthews' (1994) theory of psychological dysfunction and prior empirical studies, it was hypothesized that negative emotion would mediate the relationship between maladaptive metacognition and alcohol dependence, and maladaptive metacognition would moderate the relationship between negative emotion and alcohol dependence. A sample of 300 British college students completed the Alcohol Use Disorders Identification Test, Hospital Anxiety and Depression Scale, and Meta-Cognitions Questionnaire 30. Metacognitive traits, emotions, and alcohol dependence were positively intercorrelated. Moderated mediation modeling indicated that metacognition fosters emotion and moderates the relationship between emotion and alcohol dependence in such a way that emotion and dependence are positively associated for high metacognition and are negatively associated for low metacognition. The implications of the findings are discussed.

    Chronic alcohol abuse damages nearly every organ in the body. The harmful effects of ethanol on thebrain, the liver and the pancreas are well documented. Although chronic alcohol consumption causes serious impairments also in the gastrointestinal tract like altered motility, mucosal damage, impaired absorption of nu-trients and inflammation, the effects of chronically consumed ethanol on the enteric nervous system are less detailed. While the nitrergic myenteric neurons play an essential role in the regulation of gastrointestinal peristalsis, it was hypothesised, that these neurons are the first targets of consumed ethanol or its metabolites generated in the different gastrointestinal segments. To reinforce this hypothesis the effects of ethanol on the gastrointestinal tract was investigated in different rodent models with quantitative immunohistochemistry, in vivo and in vitro motility measurements, western blot analysis, evaluation of nitric oxide synthase enzyme activity and bio-imaging of nitric oxide synthesis. These results suggest that chronic alcohol consumption did not result significant neural loss, but primarily impaired the nitrergic pathways in gut region-dependent way leading to disturbed gastrointestinal motility. The gut segment-specific differences in the effects of chronic alcohol consumption highlight the significance the ethanol-induced neuronal microenvironment involving oxidative stress and intestinal microbiota.

    Background Ethanol is metabolized by two rate limiting reactions: alcohol dehydrogenases (ADH) convert ethanol to acetaldehyde, subsequently metabolized to acetate by aldehyde dehydrogenases (ALDH). Approximately 50% of East Asians have genetic variants that significantly impair this pathway and influence alcohol dependence (AD) vulnerability. We investigated whether variation in alcohol metabolism genes might alter the AD risk in four non-East Asian populations by performing systematic haplotype association analyses in order to maximize the chances of capturing functional variation. Methods Haplotype-tagging SNPs were genotyped using the Illumina GoldenGate platform. Genotypes were available for 40 SNPs across the ADH genes cluster and 24 SNPs across the two ALDH genes in four diverse samples that included cases (lifetime AD) and controls (no Axis 1 disorders). The case, control sample sizes were: Finnish Caucasians: 232, 194; African Americans: 267, 422; Plains American Indians: 226, 110; Southwestern American (SW) Indians: 317, 72. Results In all four populations, as well as HapMap populations, five haplotype blocks were identified across the ADH gene cluster: (1) ADH5-ADH4; (2) ADH6-ADH1A-ADH1B; (3) ADH1C; (4) intergenic; (5) ADH7. The ALDH1A1 gene was defined by four blocks and ALDH2 by one block. No haplotype or SNP association results were significant after correction for multiple comparisons; however several results, particularly for ALDH1A1 and ADH4, replicated earlier findings. There was an ALDH1A1 block 1 and 2 (extending from intron 5 to the 3′ UTR) yin yang haplotype (haplotypes that have opposite allelic configuration) association with AD in the Finns driven by SNPs rs3764435 and rs2303317 respectively, and an ALDH1A1 block 3 (including the promoter region) yin yang haplotype association in SW Indians driven by 5 SNPs, all in allelic identity. The ADH4 SNP rs3762894 was associated with AD in Plains Indians. Conclusions The systematic evaluation of

  14. Fractional amplitude analysis of low frequency fluctuation in alcohol dependent individuals: a resting state functional MRI study

    International Nuclear Information System (INIS)

    Objective: To explore brain activity features during the resting state in alcohol dependent individuals, and study the relationship between the brain activity features and alcohol dependent individuals' clinical symptoms. Methods: Twenty-four alcohol dependent individuals and 22 healthy control subjects, well matched in gender, age, education and handedness, were enrolled as the alcohol dependent group and control group respectively. A GE 3.0 T MR scanner was used to acquire all the subjects' resting state data. DPARSF software was used to process resting functional MRI data, and then the whole brain fractional amplitudes of low frequency fluctuation (fALFF) data were acquired. Two-sample t test statistical analysis was made to access fALFF difference between the two groups. Results: In comparison with the control group, the alcohol dependent group showed reduced fALFF in bilateral medial prefrontal gyrus, right inferior occipital gyrus, left precuneus,left inferior temporal gyrus, and left posterior lobe of cerebellum (0.64-1.69 vs. 0.87-1.78, t=-4.23- -2.79, P<0.05). fALFF was increased in the alcohol dependent group at the anterior cingulate,bilateral inferior frontal gyrus,right middle frontal gyrus,bilateral insular lobe,bilateral dorsal thalamus (0.86-1.82 vs. 0.76-1.58, t=3.56-3.96, P<0.05). Conclusion: Alcohol dependent individuals had abnormal activity at the bilateral prefrontal lobe,anterior cingulate, bilateral dorsal thalamus, bilateral insular lobe, left posterior lobe of cerebellum et al, during the resting state, and these abnormal activities might be related with clinical manifestation and pathophysiology.

    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.

    Full Text Available 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.

    The ratio of the lengths of the second and fourth finger (2D∶4D) has been described as reflecting the degree of prenatal androgen exposure in humans. 2D∶4D is smaller for males than females and is associated with traits such as left-handedness, physical aggression, attention-deficit-hyperactivity disorder and a genetic polymorphism of the androgen receptor. All of these traits are known to be correlated to the vulnerability for alcohol dependency. We therefore hypothesized low 2D∶4D in patients with alcohol dependency. In the present study on 131 patients suffering from alcohol dependency and 185 healthy volunteers, we found that alcohol dependent patients had smaller 2D∶4D ratios compared to controls with preserved sexual dimorphism but with reduced right-left differences. The detection of alcohol dependency based on 2D∶4D ratios was most accurate using the right hand of males (ROC-analysis: AUC 0.725, sensitivity 0.667, specificity 0.723). These findings provide novel insights into the role of prenatal androgen exposure in the development of alcohol dependency and for the use of 2D∶4D as a possible trait marker in identifying patients with alcohol dependency.

Research suggests that not only can it be useful in promoting maintenance of alcohol abstinence but also it may play a key role in decreasing alcohol cravings and anxiety often associated with alcohol dependence. To assess the benefit of baclofen for alcohol dependence, a review of the literature was conducted to identify published data investigating this off-label treatment. Four randomized controlled trials to date have been published and were included in this review. Although primary outcomes differ between studies, patients randomized to baclofen experience higher rates of abstinence from alcohol than those taking placebo in two of the trials. Secondary analyses indicate that baclofen is safe in patients with alcohol dependence, including those with moderate to severe liver cirrhosis, and may provide beneficial anxiolytic effects. Despite some positive data, the largest available randomized controlled trial failed to find any differences between baclofen and placebo. In all studies, individuals with severe medical comorbidities, seizure disorders, and psychiatric disorders were excluded from trials, which may limit external validity. In summary, there may be beneficial effects from using baclofen for the treatment of alcohol dependence; however, limited conclusions can be drawn from the small number of studies

  1. Neuropeptide Y (NPY) in the extended amygdala is recruited during the transition to alcohol dependence.

    2012-12-01

    Neuropeptide Y (NPY) is abundant in the extended amygdala, a conceptual macrostructure in the basal forebrain important for regulation of negative affective states. NPY has been attributed a central role in anxiety-like behavior, fear, nociception, and reward in rodents. Deletion of the NPY gene in mice produces a high-anxiety high-alcohol-drinking phenotype. NPY infused into the brains of rats selectively bred to consume high quantities of alcohol suppresses alcohol drinking by those animals, an effect that is mediated by central amygdala (CeA). Likewise, alcohol-preferring rats exhibit basal NPY deficits in CeA. NPY infused into the brains of alcohol-dependent rats blocks excessive alcohol drinking by those animals, an effect that also has been localized to the CeA. NPY in CeA may rescue dependence-induced increases in anxiety and alcohol drinking via inhibition of downstream effector regions that receive GABAergic inputs from CeA. It is hypothesized here that NPY modulates anxiety-like behavior via Y2R regulation of NPY release, whereas NPY modulation of alcohol-drinking behavior in alcohol-dependent animals occurs via Y2R regulation of GABA release.

  2. SOME PERSONALITY FEATURES AS PREDICTIVE FACTORS OF DRUG AND ALCOHOL ABUSE AND DEPENDENCY

    Full Text Available Similar to other behavioural disorders, models of drug and alcohol abuse stem from interaction of several factors such as social settings, biological and psychological configuration, individual’s personality dimensions as well as psychoactive effect of drug. To-date research predominantly targeted consequences of drug and alcohol abuse, treatment, rehabilitation and the explanation of dependent person’s behaviour. Much less effort and research addressed the issue of personality as a potent predisposition risk factor and its effect on this phenomenon. Although personality does not develop as a separate entity, drug abuse, amongst other factors, is initiated by different personality traits, cognitive processes, person’s expectancies and psychopathology. In the light of that, this article contains results of psychological research which indicate risk factors and their interactive relationships within general personality construct. These findings therefore relevantly contribute to the development of effective prevention programmes, risk groups identification and early treatment interventions.

  3. Alcoholic cardiomyopathy : The result of dosage and individual predisposition.

    The individual amount of alcohol consumed acutely or chronically decides on harm or benefit to a person's health. Available data suggest that one to two drinks in men and one drink in women will benefit the cardiovascular system over time, one drink being 17.6 ml 100 % alcohol. Moderate drinking can reduce the incidence and mortality of coronary artery disease, heart failure, diabetes, ischemic and hemorrhagic stroke. More than this amount can lead to alcoholic cardiomyopathy, which is defined as alcohol toxicity to the heart muscle itself by ethanol and its metabolites. Historical examples of interest are the Munich beer heart and the Tübingen wine heart. Associated with chronic alcohol abuse but having different etiologies are beriberi heart disease (vitamin B1 deficiency) and cardiac cirrhosis as hyperdynamic cardiomyopathies, arsenic poising in the Manchester beer epidemic, and cobalt intoxication in Quebec beer drinker's disease. Chronic heavy alcohol abuse will also increase blood pressure and cause a downregulation of the immune system that could lead to increased susceptibility to infections, which in turn could add to the development of heart failure. Myocardial tissue analysis resembles idiopathic cardiomyopathy or chronic myocarditis. In the diagnostic work-up of alcoholic cardiomyopathy, the confirmation of alcohol abuse by carbohydrate deficient transferrin (CDT) and increased liver enzymes, and the involvement of the heart by markers of heart failure (e.g., NT-proBNP) and of necrosis (e.g., troponins or CKMb) is mandatory. Treatment of alcoholic cardiomyopathy consists of alcohol abstinence and heart failure medication. PMID:27582365

  4. On the relationship between emotional state and abnormal unfairness sensitivity in alcohol dependence

    Full Text Available Recent empirical findings suggest that alcohol dependence is characterized by heightened sensitivity to unfairness during social transactions. The present study went a step further and aimed to ascertain whether this abnormal level of sensitivity to unfairness is underlined by an increased emotional reactivity. Twenty-six recently abstinent alcohol-dependent individuals (AD and 32 controls performed an Ultimatum Game (UG, in which participants had to respond to take-it-or-leave-it offers, ranging from fair to unfair and made by a fictive proposer. Emotional state was recorded during UG offers presentation and was indexed by the amplitude of skin conductance response (SCR. Results showed that AD decided to reject unfair offers more frequently than their controls, confirming previous data. The proportion of rejected unfair UG offers was correlated with SCR, in the AD but not in the control group. This finding suggests that deciding to accept or reject unfair UG offers is influenced by arousal-affective activity in AD, but not in controls. Heightened emotional reactivity may have driven AD to punish the proposer rather than acting as a rational economic agent. An implication of present findings is that AD might have difficult to cope with unfair situations triggered by social interactions. Future studies are needed are needed in order to examine whether - emotional and behavioral - reactivity to unfairness during the UG could impact alcohol consumption and relapse in AD.

The present study went a step further and aimed to ascertain whether this abnormal level of sensitivity to unfairness is underlined by an increased emotional reactivity. Twenty-six recently abstinent alcohol-dependent (AD) individuals and 32 controls performed an ultimatum game (UG), in which participants had to respond to take-it-or-leave-it offers, ranging from fair to unfair and made by a fictive proposer. Emotional state was recorded during UG offers presentation and was indexed by the amplitude of skin conductance response (SCR). Results showed that AD decided to reject unfair offers more frequently than their controls, confirming previous data. The proportion of rejected unfair UG offers was correlated with SCR, in the AD but not in the control group. This finding suggests that deciding to accept or reject unfair UG offers is influenced by arousal-affective activity in AD, but not in controls. Heightened emotional reactivity may have driven AD to punish the proposer rather than acting as a rational economic agent. An implication of present findings is that AD might have difficult to cope with unfair situations triggered by social interactions. Future studies are needed in order to examine whether—emotional and behavioral—reactivity to unfairness during the UG could impact alcohol consumption and relapse in AD. PMID:26217293

    The hypothesis that dependency conflict is associated with higher levels of alcohol consumption when dependency needs are threatened or thwarted was tested with a sample of 672 middle-aged, married adults with college-age children. The subjects' current level of alcohol consumption was predicted based on the present level of threat to the marital relationship (assessed by reports from several family members) and on indices of dependency need and inhibition of dependent behavior estimated from sibship size, sibship density, and sibling position. A multiple regression analysis yielded a significant two-way interaction (p less than .05) between marital threat and subject sex, and a significant three-way interaction of dependency need, inhibition of dependent behavior, and marital threat. High marital threat was associated with higher levels of alcohol consumption in men and slightly lower levels of alcohol consumption in women. Additionally, when dependency need was high, alcohol consumption was generally low, except when both inhibition of dependent behavior and marital threat were high. However, when dependency need was low, the highest alcohol consumption score occurred when marital threat was low and inhibition was high.

    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.

    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.

    Full Text Available Co-occurrence of alcohol dependence with other mental disorders is very common, being important cause of diagnostic and therapeutic difficulties. There is a lack of systemic solutions in mental health care dedicated to the patients with dual diagnosis. The literature on the topic of treatment of patients with dual diagnosis is limited. While comorbidity of alcohol dependence with mental disorders is prevalent, there is rising interest among researchers on that issue. In this paper we present current hypotheses on pathogenesis of dual diagnosis as well as recommendations for its treatment. The role of disturbances in functioning of hypothalamic-pituitary-adrenal axis in pathogenesis of co-occurrence of alcohol dependence with anxiety and affective disorders is presented. Researchers studying dual diagnosis underline the fact that simultaneous treatment of alcohol dependence and co-occurring psychiatric disorders increases the chance to improve patients` functioning. Inappropriate treatment without complete management of all existing problems may make full recovery impossible.

    Full Text Available Co - morbidity is “the occurrence of 2 or more distinct psychiatric disorders at the same time”. Clinical and general population studies show that alcohol abuse or dependence and major depression often coexist. The presenc e of co - morbid conditions, such as alcohol dependence (AD and major depression, has important implications for patient functioning and prognosis, including difficulties in case identification, treatment effectiveness and compliance, altered pharmacokineti cs, and increased chronicity of both conditions. Although depression and alcohol dependence commonly coexist in community and treatment - seeking populations, there is no clear consensus on appropriate assessment and treatment of patients who present with sy mptoms of both disorders. To make appropriate treatment decisions, clinicians must know the likely effects of depression on drinking outcomes. This article reviews the relation between co - morbid depression and alcohol dependence.

    2008-01-01

    The aim of this study was to investigate the relationship of self-mutilative behavior with dissociative experiences among men who are alcohol dependent. Participants were 176 inpatients consecutively admitted to an alcohol dependency treatment center. Dissociative Experiences Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, Symptom Checklist-Revised, and Michigan Alcoholism Screening Test were conducted to all participants. A sizable proportion of patients (29.0%) reported self-mutilation (SM). Childhood abuse, younger age, early onset of alcoholism, and dissociative taxon membership predicted SM. The overall severity of clinical condition and the frequency of suicide attempts among those who reported SM were higher than those of the remaining patients. The Dissociative Experiences Scale-Taxon item "auditory verbal hallucinations" and the Symptom Checklist-Revised dimension "hostility" were predictors of SM. There is a complex relationship between dissociation, alcohol use, and SM. Increased awareness among clinicians on this relationship may increase the effectiveness of treatment interventions.

    Full Text Available Katie Witkiewitz, Kimber Saville, Kacie HamreusDepartment of Psychology, Washington State University Vancouver, Vancouver, WA, USAAbstract: Acamprosate, or N-acetyl homotaurine, is an N-methyl-D-aspartate receptor modulator approved by the Food and Drug Administration (FDA as a pharmacological treatment for alcohol dependence. The exact mechanism of action of acamprosate is still under investigation, but the drug appears to work by promoting a balance between the excitatory and inhibitory neurotransmitters, glutamate and gamma-aminobutyric acid, respectively, and it may help individuals with alcohol dependence by reducing withdrawal-associated distress. Acamprosate has low bioavailability, but also has an excellent tolerability and safety profile. In comparison with naltrexone and disulfiram, which are the other FDA-approved treatments for alcohol dependence, acamprosate is unique in that it is not metabolized by the liver and is also not impacted by alcohol use, so can be administered to patients with hepatitis or liver disease (a common comorbid condition among individuals with alcohol dependence and to patients who continue drinking alcohol. Acamprosate has demonstrated its efficacy in more than 25 placebo-controlled, double-blind trials for individuals with alcohol dependence, and has generally been found to be more efficacious than placebo in significantly reducing the risk of returning to any drinking and increasing the cumulative duration of abstinence. However, acamprosate appears to be no more efficacious than placebo in reducing heavy drinking days. Numerous trials have found that acamprosate is not significantly more efficacious than naltrexone or disulfiram, and the efficacy of acamprosate does not appear to be improved by combining acamprosate with other active medications (eg, naltrexone or with psychosocial treatment (eg, cognitive-behavioral therapy.

    Full Text Available The paper analyzes the psychological characteristics of alcohol-dependent women, including the particularities of subjective psychological symptomatic status, psychological well-being, motivation, social desirability and self-esteem. We tested the hypothesis that: 1 alcohol-dependent women expressed less motivation of social desirability and expressed more subjectively perceived symptoms in comparison with normal; 2 alcohol-dependent women have lower levels of well-being, self-esteem and level of aspiration in comparison with the conventional norm. The experimental group consisted of 46 women (mean age 45 years who are dependent on alcohol. The comparison group included 33 women with normal behavior who are not dependent on alcohol (the average age 33 years. We have found that a statistically significant contribution to the classification of women in a group of alcohol-dependent is made by low self-esteem, high levels of anxiety, low real self-evaluation of their success in business, willpower and mental health, low ideal self-evaluation in terms of the happiness and mind, achievable self-evaluation in terms of the happiness and visual attractiveness, the average level of the personal growth as basic component of well-being.

    Full Text Available Abstract Background Most people being treated for alcoholism are unable to successfully quit drinking within their treatment programs. In few cases do we know the full picture of how abstinence is achieved in Taiwan. We tracked processes of abstinence in alcohol-dependency disorders, based on study evidence and results. This research explores the process of recovery from the viewpoint of the alcohol-dependent. Methods Semi-structured interviews were conducted in two different settings, using purpose sampling, during 2003-2004. The data were analyzed using content analysis. Participants were 32 adults, purposefully selected from an Alcoholics Anonymous group and a psychiatric hospital in North Taiwan. Results We found that the abstinence process is an ongoing process, in which the alcohol-dependent free themselves of addiction progressively. This process never ends or resolves in complete recovery. We have identified three stages in the struggle against alcoholism: the Indulgence, Ambivalence and Attempt (IAA cycle, in which the sufferer is trapped in a cycle of attempting to give up and failing; the Turning Point, in which a Personal Nadir is reached, and the Ongoing Process of abstinence, in which a constant effort is made to remain sober through willpower and with the help of support groups. We also discuss Influencing Factors that can derail abstinence attempts, pushing the sufferer back into the IAA cycle. Conclusion This study provides important points of reference for alcohol and drug service workers and community healthcare professionals in Taiwan, casting light on the abstinence process and providing a basis for intervention or rehabilitation services.

    2010-01-01

    Full Text Available The psychopharmacology of alcohol dependence is today poised at interesting crossroads. Three major drugs Naltrexone, Disulfiram and Acamprosate have been tried and tested in various trials and have many meta-analyses each to support them. While Naltrexone may reduce craving, Acamprosate scores on cost effectiveness worldwide with Disulfiram being an alcohol deterrent drug. Studies support, refute and criticize the use of each of these drugs. Combining one or more of them is also a trend seen. The most important factor in efficacy has been the combination of psychosocial treatment with medication. Studies from the early 1970s to date have been reviewed and the findings presented in a manner useful for the busy clinician to judge the best pharmacological option in the management of alcohol dependence. The role of depot disulfiram, naltrexone, and medications like Topiramate and SSRIs under research for alcohol dependence, are also addressed.

    Alcohol dependence (AD) is a complex and heterogeneous disorder. The identification of more homogeneous subgroups of individuals with drinking problems and the refinement of the diagnostic criteria are inter-related research goals. They have the potential to improve our knowledge of etiology and treatment effects, and to assist in the identification of risk factors or specific genetic factors. Mixture modeling has advantages over traditional modeling that focuses on either the dimensional or categorical latent structure. The mixture modeling combines both latent class and latent trait models, but has not been widely applied in substance use research. The goal of the present study is to assess whether the AD criteria in the population could be better characterized by a continuous dimension, a few discrete subgroups, or a combination of the two. More than seven thousand participants were recruited from the population-based Virginia Twin Registry, and were interviewed to obtain DSM-IV (Diagnostic and Statistical Manual of Mental Disorder, version IV) symptoms and diagnosis of AD. We applied factor analysis, latent class analysis, and factor mixture models for symptom items based on the DSM-IV criteria. Our results showed that a mixture model with 1 factor and 3 classes for both genders fit well. The 3 classes were a non-problem drinking group and severe and moderate drinking problem groups. By contrast, models constrained to conform to DSM-IV diagnostic criteria were rejected by model fitting indices providing empirical evidence for heterogeneity in the AD diagnosis. Classification analysis showed different characteristics across subgroups, including alcohol-caused behavioral problems, comorbid disorders, age at onset for alcohol-related milestones, and personality. Clinically, the expanded classification of AD may aid in identifying suitable treatments, interventions and additional sources of comorbidity based on these more homogenous subgroups of alcohol use

    Previous research has linked emotional instability with problematic alcohol use. This may be a function of increased "hot" information processing (which is relatively automatic in nature and highly influenced by emotional states) for individuals with more emotional instability. According to dual-process models, cognitive control may attenuate the impact of emotional instability by preventing an overreliance on hot information processing. It was hypothesized that emotional instability would be positively associated with alcohol-related consequences, but that cognitive control would moderate this association. Participants were undergraduate students (n = 80) who endorsed drinking at moderate levels. Participants completed laboratory assessments of emotional instability, alcohol use and its consequences, and cognitive control. An observed variable path model examined the association between emotional instability and alcohol problems. Consistent with hypotheses, emotional instability was positively associated with alcohol consequences, and this relationship was moderated by cognitive control, at least for dependence symptoms. At low levels of cognitive control, there was a positive association between emotional instability and dependence symptoms (β = 0.514, p Emotional instability may promote alcohol dependence via an overreliance on hot information processing. Consistent with dual-process theory, this relationship is diminished among individuals with more cognitive control. Interventions focusing on increasing cognitive control may be effective in reducing alcohol pathology associated with emotional instability. (PsycINFO Database Record

Family harmony was rated by mothers and fathers in adolescence, and young adults' substance dependence diagnoses were obtained through structured interviews. Higher FHD predicted lower adolescent family harmony, which in turn increased young adults' odds of being diagnosed with drug dependence (with and without alcohol dependence) compared to no diagnoses or to alcohol dependence only. Family harmony also interacted with FHD such that the protective effect of family harmony on young adults' drug dependence with or without alcohol dependence decreased as FHD rose, and was nonsignificant at high levels of FHD. The findings suggest the importance of distinguishing among alcohol and drug dependence disorders and examining their differential etiological pathways, and also suggest that the protective effects of harmonious family environments on substance dependence may be limited at high levels of FHD.

    2014-01-01

    Background: Koob's allostatic model of addiction emphasizes the transition from positive reinforcement to negative reinforcement as dependence develops. This study seeks to extend this well-established neurobiological model to humans by examining subjective response to alcohol (SR) as a biobehavioral marker of alcohol reinforcement. Specifically, this study examines (a) differential SR in heavy drinkers (HDs) vs. alcohol dependent individuals (ADs) and (b) whether HDs and ADs differ in terms ...

    Full Text Available These analyses of the COMBINE Study examined the effects of naltrexone among non-abstainers. Given that one of the most well-established mechanisms of action of naltrexone involves blunting of alcohol reward, it is hypothesized that naltrexone should be more effective among individuals who drank during treatment. Participants were 952 (78% of the total COMBINE Study sample treatment-seeking alcohol dependent men and women who received pharmacotherapy for alcoholism and drank at least once during the 16-week trial. Mixed model analyses revealed that individuals who drank more regularly during the trial seemed to benefit most from naltrexone and the effects of naltrexone on heavy drinking was significant in treatment months 2 through 4 among individuals who reported drinking on 81, 68, and 60% or more of days, respectively. Those drinking frequencies were observed in 11, 15, and 19% of the sample. Similar effects were not observed for drinks per drinking day. These results suggest that a small subgroup of non-abstainers, composed primarily of very regular drinkers, appears to benefit from naltrexone in reducing heavy drinking days. Naltrexone may be effective in the context of controlled drinking approaches, even among very frequent drinkers.

    2011-01-01

    A retrospective patient record review was conducted to examine comorbid psychiatric diagnoses, and comorbid substance use, among 465 patients below 45 years of age, presenting to a national alcohol addiction treatment unit in Dublin, between 1995 and 2006. Rates were high for depressive disorder (25.3%) particularly among females (35.4%). Lifetime reported use of substances other than alcohol was 39.2%, and further analysis showed significantly higher rates of deliberate self-harm among this group. Lifetime reported use of ecstasy was also significantly associated with depression in this alcohol-dependent population using logistic regression analysis. Implications and limitations of the findings are discussed.

    This study had three objectives: (1) to assess the relationship between the single nucleotide polymorphism (SNP) rs1789891 in the alcohol dehydrogenase gene cluster and alcohol dependence and affective disorders; (2) to assess the differences in the Regulative Theory of Temperament (RTT) traits between an alcohol dependent group, an affective disorders group, and a healthy group; and (3) to assess the relationship between rs1789891 and temperament traits in a healthy group, taking into account the interaction of genotype and sex. The SNP rs1789891 was genotyped in a group of 194 alcohol dependent men, aged 21 to 71 years; 137 patients with affective disorders, including 51 males and 86 females, aged 19 to 85 years; and a group of 207 healthy individuals, including 89 males and 118 females, aged 18 to 71 years. Temperament traits (briskness, perseveration, sensory sensitivity, emotional reactivity, endurance, and activity) were assessed in all groups using the Formal Characteristics of Behaviour-Temperament Inventory. The comparative analysis of genotypic frequencies showed no significant differences between patients with alcoholism or affective disorders and those in the control group. Alcohol dependent men and the affective disorder group were characterised by higher levels of emotional reactivity (p-value 1.4e-5 and 9.84e-7, respectively) and lower levels of briskness, sensory sensitivity, endurance, and activity (p-value from 3.76e-8 to 0.012) when compared to the healthy group. The rs1789891 polymorphism was associated with briskness (p = 0.02), sensory sensitivity (p = 0.036), and activity (p = 0.049). None of the results were statistically significant after Bonferroni correction.

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

    Alcohol use disorders (AUDs), and alcohol dependence (AD) in particular, are prevalent and associated with a large burden of disability and mortality. The aim of this study was to estimate prevalence of AD in the European Union (EU), Iceland, Norway, and Switzerland for the year 2010, and to investigate potential influencing factors. The 1-year prevalence of AD in the EU was estimated at 3.4% among people 18-64 years of age in Europe (women 1.7%, men 5.2%), resulting in close to 11 million affected people. Taking into account all people of all ages, AD, abuse and harmful use resulted in an estimate of 23 million affected people. Prevalence of AD varied widely between European countries, and was significantly impacted by drinking cultures and social norms. Correlations with level of drinking and other drinking variables and with major known outcomes of heavy drinking, such as liver cirrhosis or injury, were moderate. These results suggest a need to rethink the definition of AUDs.

    Full Text Available Background and Objectives: The objective of the present study was to obtain information about the prevalence of addiction disorders in ADHD patients in a German study population, to compare the prevalence of addiction disorders in ADHD patients to that in the normal population according to the German Epidemiological Addiction Survey, and to determine which drugs are consumed most by ADHD patients. Participants: The sample consisted of 61 patients (average age 35.11 ± 9.33 years from our ADHD consultation who were consecutively included in our study over a period of 12 months. Measurements: We diagnosed ADHD according to DSM-IV-R and by assessing the WURS-k, CAARS and BROWN ADD scales. For diagnosing addiction we conducted the EuropASI, the IDCL, the QOD and the FTNA. For differential diagnosis we assessed the SCL-K. Results: About half of our study population of ADHD patients were diagnosed with a dependence disorder (50.8%, n = 31. Twenty one dot three percent (n = 13 were suffering from an alcohol dependence, 13.1% (n = 8 from a substance use disorder (SUD and 18% (n = 11 from a combination of both addictions. The drug consumed most commonly by ADHD patients was cannabis. Alcohol and substance abuse commenced significantly earlier in patients with ADHD than in patients with addiction disorders without comorbid ADHD. Conclusions: Our data show that the risk of developing a dependence disorder is elevated in ADHD patients. Clinicians should bear in mind that the characteristics of a dependence in ADHD patients are clinically more pronounced and that an addiction in ADHD patients starts earlier than usually expected.

  10. Thought suppression, impaired regulation of urges, and Addiction-Stroop predict affect-modulated cue-reactivity among alcohol dependent adults.

    Abstinent alcohol dependent individuals commonly employ thought suppression to cope with stress and intrusive cognitions about alcohol. This strategy may inadvertently bias attention towards 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 × 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

  11. Comparison of breath-alcohol screening test results with venous blood alcohol concentration in suspected drunken drivers.

    Hand-held electronic breath-alcohol analyzers are widely used by police authorities in their efforts to detect drunken drivers and to improve road-traffic safety. Over a three month period, the results of roadside breath-alcohol tests of drivers apprehended in Finland were compared with venous blood alcohol concentration (BAC). The mean (median) time between sampling blood and breath was 0.71h (0.58h) with a range from 0 to 6h. Some hand-held instruments gave results as the concentration of alcohol in breath and were converted into BAC assuming a blood-breath alcohol ratio (BBR) of 2260. The mean venous BAC (1.82g/kg) in traffic offenders was higher than the result predicted by the hand-held breath analyzers (1.72g/kg). In 1875 roadside tests, the relationship between venous BAC (x) and BrAC (y) was defined by the regression equation y=0.18+0.85x. The coefficients show both a constant bias (y-intercept 0.18g/kg) and a proportional bias (slope=0.85). The residual standard deviation (SD), an indicator of random variation, was ±0.40g/kg. After BAC results were corrected for the time elapsed between sampling blood and breath, the y-intercept decreased to 0.10g/kg and 0.004g/kg, respectively, when low (0.1g/kg/h) and high (0.25g/kg/h) rates of alcohol elimination were used. The proportional bias of 0.85 shows that the breath-alcohol test result reads lower than the actual BAC by 15% on average. This suggests that the BBR of 2260 used for calibration should be increased by about 15% to give closer agreement between BAC and BrAC. Because of the large random variation (SD±0.40g/kg), there is considerable uncertainty if and when results from the roadside screening test are used to estimate venous BAC. The roadside breath-alcohol screening instruments worked well for the purpose of selecting drivers above the statutory limit of 0.50g/kg.

    We investigated relationships between drinking, other drug use, and drug craving, using ecological momentary assessment (EMA), in a sample of polydrug users who were not heavy drinkers. In a prospective longitudinal cohort study, 114 heroin and cocaine users on methadone-maintenance treatment carried handheld electronic diaries during waking hours and were screened for drug and alcohol use for up to 25 weeks. Individuals who fulfilled the Diagnostic and Statistical Manual of Mental Disorders criteria for alcohol abuse or dependence were excluded. Participants responded to 2-5 random prompts per day to report on their moods, cravings, and activities and initiated entries when they used or acutely craved heroin or cocaine. Drinking alcohol was assessed in both types of entries. Breath alcohol was measured three times weekly. Participants reported drinking alcohol in 1.6% of random-prompt entries, 3.7% of event-contingent entries when craving cocaine and/or heroin, and 11.6% of event-contingent entries when using cocaine and/or heroin. Alcohol drinking was also associated with higher craving ratings and prestudy alcohol use. More drinking was detected by ambulatory self-report than by in-clinic breath testing. Even though we had screened out heavy drinkers from our sample of polydrug users, drinking was associated with heroin and cocaine craving and actual use. PMID:27579810

    Impulsivity is a risk factor for alcoholism, and long-term alcohol exposure may further impair impulse control in a manner that propels problematic alcohol use. The present study employed the rat 5-choice serial reaction time task (5-CSRTT) to measure behavioral inhibition and attentional capacity during abstinence from repeated 5-day cycles of alcohol liquid diet consumption. Task performance was not disrupted following the first cycle of alcohol exposure; however, evidence of impaired behavioral inhibition emerged following the third cycle of alcohol exposure. In comparison with controls, alcoholic rats exhibited deficits in inhibitory control during cognitively challenging 5-CSRTT tests employing variable intertrial interval (varITI). This behavioral disruption was not present during early abstinence (3 days) but was evident by 7 days of abstinence and persisted for at least 34 days. Interestingly, renewed alcohol consumption ameliorated these disruptions in impulse control, although deficient behavioral inhibition re-emerged during subsequent abstinence. Indices of increased impulsivity were no longer present in tests conducted after 49 days of abstinence. Alcohol-related impairments in impulse control were not evident in sessions employing highly familiar task parameters regardless of the abstinence period, and control experiments confirmed that performance deficits during the challenge sessions were unlikely to result from alcohol-related disruption in the adaptation to repeated varITI testing. Together, the current findings demonstrate that chronic intermittent alcohol consumption results in decreased behavioral inhibition in rats that is temporally similar to clinical observations of disrupted impulsive control in abstinent alcoholics performing tasks of behavioral inhibition.

    Several authors have shown that alexithymia, emotional and perceptual dependency characterize patients suffering from substance abuse. The aim of the study is to test the hypothesis that the emotional and cognitive components of alexithymia are associated with dependency in alcoholics. Three groups were investigated: 60 inpatients meeting the DSM-IV criteria for alcohol dependence, 57 healthy subjects, 144 university students. All subjects completed the following rating scales: The 20-item Toronto Alexithymia Scale (TAS-20), the Interpersonal Dependency Inventory (IDI), the Beck Depression Inventory (BDI), and the Embedded Figures Test (EFT). Partial correlations, using the BDI score as constant, were calculated. In normal subjects, the 'Emotion' subscale of the TAS-20 correlated with the 'Lack of social self-confidence' subscale of the IDI and the 'Cognitive' subscale of the TAS-20 did not correlate with the EFT score. In alcoholics, the 'Cognitive' subscale of the TAS-20 correlated with the 'Lack of social self-confidence' subscale, with the EFT score and with the 'Affirmation of autonomy' subscale. A particular cognitive style characterized by externally oriented thinking, affirmation of autonomy as denial of emotional dependency and field dependence could characterize alcoholics.

    2011-05-01

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

    Full Text Available Abstract Background Cognitive factors associated with drinking behavior such as positive alcohol expectancies, self-efficacy, perception of impaired control over drinking and perception of drinking problems are considered to have a significant influence on treatment effects and outcome in alcohol-dependent patients. However, the development of a rating scale on lack of perception or denial of drinking problems and impaired control over drinking has not been substantial, even though these are important factors in patients under abstinence-oriented treatment as well as participants in self-help groups such as Alcoholics Anonymous (AA. The Drinking-Related Cognitions Scale (DRCS is a new self-reported rating scale developed to briefly measure cognitive factors associated with drinking behavior in alcohol-dependent patients under abstinence-oriented treatment, including positive alcohol expectancies, abstinence self-efficacy, perception of impaired control over drinking, and perception of drinking problems. Here, we conducted a prospective cohort study to explore the predictive validity of DRCS. Methods Participants in this study were 175 middle-aged and elderly Japanese male patients who met the DSM-IV Diagnostic Criteria for Alcohol Dependence. DRCS scores were recorded before and after the inpatient abstinence-oriented treatment program, and treatment outcome was evaluated one year after discharge. Results Of the 175 participants, 30 were not available for follow-up; thus the number of subjects for analysis in this study was 145. When the total DRCS score and subscale scores were compared before and after inpatient treatment, a significant increase was seen for both scores. Both the total DRCS score and each subscale score were significantly related to total abstinence, percentage of abstinent days, and the first drinking occasion during the one-year post-treatment period. Therefore, good treatment outcome was significantly predicted by low

  19. The effect of alcohols on red blood cell mechanical properties and membrane fluidity depends on their molecular size.

    Directory of Open Access Journals (Sweden)

    Melda Sonmez

    Full Text Available The role of membrane fluidity in determining red blood cell (RBC deformability has been suggested by a number of studies. The present investigation evaluated alterations of RBC membrane fluidity, deformability and stability in the presence of four linear alcohols (methanol, ethanol, propanol and butanol using ektacytometry and electron paramagnetic resonance (EPR spectroscopy. All alcohols had a biphasic effect on deformability such that it increased then decreased with increasing concentration; the critical concentration for reversal was an inverse function of molecular size. EPR results showed biphasic changes of near-surface fluidity (i.e., increase then decrease and a decreased fluidity of the lipid core; rank order of effectiveness was butanol > propanol > ethanol > methanol, with a significant correlation between near-surface fluidity and deformability (r = 0.697; p<0.01. The presence of alcohol enhanced the impairment of RBC deformability caused by subjecting cells to 100 Pa shear stress for 300 s, with significant differences from control being observed at higher concentrations of all four alcohols. The level of hemolysis was dependent on molecular size and concentration, whereas echinocytic shape transformation (i.e., biconcave disc to crenated morphology was observed only for ethanol and propanol. These results are in accordance with available data obtained on model membranes. They document the presence of mechanical links between RBC deformability and near-surface membrane fluidity, chain length-dependence of the ability of alcohols to alter RBC mechanical behavior, and the biphasic response of RBC deformability and near-surface membrane fluidity to increasing alcohol concentrations.

    Isopropanol (IPA) is an important solvent used in industrial activity often found in hospitals as antiseptic alcohol rub. Also, IPA may have the potential to be a biomarker of diabetic ketoacidosis. In this study, an optical biosensor using NADH-dependent secondary alcohol dehydrogenase (S-ADH) for IPA measurement was constructed and evaluated. An ultraviolet light emitting diode (UV-LED, λ=340nm) was employed as the excitation light to excite nicotinamide adenine dinucleotide (NADH). A photomultiplier tube (PMT) was connected to a two-way branch optical fiber for measuring the fluorescence emitted from the NADH. S-ADH was immobilized on the membrane to catalyze IPA to acetone and reduce NAD(+) to be NADH. This IPA biosensor shows highly sensitivity and selectivity, the calibration range is from 500 nmol L(-1) to 1mmolL(-1). The optimization of buffer pH, temperature, and the enzyme-immobilized method were also evaluated. The detection of IPA in nail related cosmetic using our IPA biosensor was also carried out. The results showed that large amounts of IPA were used in these kinds of cosmetics. This IPA biosensor comes with the advantages of rapid reaction, good reproducibility, and wide dynamic range, and is also expected to use for clinical IPA detections in serum or other medical and health related applications.

    There are many negative health consequences associated with alcohol dependency. Fractures of the proximal femur carry significant morbidity and mortality. This study examines the outcomes in patients with alcohol dependency, who sustain a fracture of the proximal femur. Twenty-eight consecutive alcohol dependent patients who suffered a fracture of the proximal femur were identified over a three year period. Data were collected on demographics, co-morbidity, surgical factors, mobility and mortality. The median age of patients was 61 years. The median weekly alcohol intake was 158 units. Thirteen patients sustained an extra-capsular fracture and 15 an intra-capsular proximal femoral fracture. Twenty-two fractures were treated with internal fixation and six with arthroplasty. The overall mortality rate was 29% at a median of 15 months post fracture. The failure rate of intra-capsular fractures fixed with cannulated screws was 56% at a median time of 43 days. All patients had a reduction in mobility compared to their pre-operative function. The reduction in mobility was greatest in patients with intra-capsular fractures treated with cannulated screw fixation. Alcohol dependent patients sustaining a fracture of the proximal femur are significantly younger than non-alcohol dependent patients sustaining the same injury. Despite the younger age at presentation the one year mortality rate of this group was high (29%). The high rate of complications with fracture fixation and high one year mortality suggest that hemiarthroplasty may be the best treatment option for intra-capsular fractures in this patient group.

    Neuroimaging studies have dramatically advanced our understanding of the neurochemical basis of alcohol dependence, a major public health issue. In this paper, we review the research generated from neurochemical specific imaging modalities including magnetic resonance spectroscopy, positron emission tomography, and single-photon emission computed tomography in studies of alcohol dependence and withdrawal. We focus on studies interrogating γ-aminobutyric acid (GABA), glutamate, and dopamine, as these are prominent neurotransmitter systems implicated in alcohol dependence. Highlighted findings include diminished dopaminergic functioning and modulation of the GABA system by tobacco smoking during alcohol withdrawal. Then, we consider how these findings impact the clinical treatment of alcohol dependence and discuss directions for future experiments to address existing gaps in the literature, for example, sex differences and smoking comorbidity. These and other considerations provide opportunities to build upon the current neurochemistry imaging literature of alcohol dependence and withdrawal, which may usher in improved therapeutic and relapse prevention strategies.

    Full Text Available SummaryIntroduction:alcohol is a psychotropic depressant of the central nervous system (CNS that promotes simultaneous changes in several neuronal pathways, exerting a profound neurological impact that leads to various behavioral and biological alterations.Objectives:to describe the effects of alcohol on the CNS, identifying the signaling pathways that are modified and the biological effects resulting from its consumption.Methods:a literature review was conducted and articles published in different languages over the last 15 years were retrieved.Results:the studies reviewed describe the direct effect of alcohol on several neurotransmitter receptors (gamma-aminobutyric acid [GABA], glutamate, endocannabinoids AEA and 2-AG, among others, the indirect effect of alcohol on the limbic and opioid systems, and the effect on calcium and potassium channels and on proteins regulated by GABA in the hippocampus.Discussion and conclusion:the multiple actions of alcohol on the CNS result in a general effect of psychomotor depression, difficulties in information storage and logical reasoning and motor incoordination, in addition to stimulating the reward system, a fact that may explain the development of addiction. Knowledge on the neuronal signaling pathways that are altered by alcohol allows the identification of effectors which could reduce its central action, thus, offering new therapeutic perspectives for the rehabilitation of alcohol addicts.

  10. Disulfiram efficacy in the treatment of alcohol dependence: a meta-analysis.

    Marilyn D Skinner

    Full Text Available BACKGROUND: Despite its success with compliant or supervised patients, disulfiram has been a controversial medication in the treatment of alcoholism. Often, study designs did not recognize a pivotal factor in disulfiram research, the importance of an open-label design. Our objectives are: (1 to analyze the efficacy and safety of disulfiram in RCTs in supporting abstinence and (2 to compare blind versus open-label studies, hypothesizing that blinded studies would show no difference between disulfiram and control groups because the threat would be evenly spread across all groups. METHODS AND FINDINGS: We searched PubMed, EMBASE and the Cochrane Central Register for RCTs on disulfiram use with alcoholics in comparison to any alcoholic control group. The primary outcome was defined by the authors of each trial. Additional analyses included: blind vs. open-label, with or without supervision, cocaine study or not, and type of control. Overall, the 22 included studies showed a higher success rate of disulfiram compared to controls Hedges'g = .58 (95%CI = .35-.82. When comparing blind and open-label RCTs, only open-label trials showed a significant superiority over controls g = .70 (95%CI = .46-.93. RCTs with blind designs showed no efficacy of disulfiram compared to controls. Disulfiram was also more effective than the control condition when compared to naltrexone g = .77, 95%CI = .52-1.02, to acamprosate g = .76, 95%CI = .04-1.48, and to the no disulfiram groups g = .43, 95%CI = .17-.69. LIMITS INCLUDE: (1 a population of 89% male subjects and (2 a high but unavoidable heterogeneity of the studies with a substantial I-square in most subgroups of studies. CONCLUSIONS: Blinded studies were incapable of distinguishing a difference between treatment groups and thus are incompatible with disulfiram research. Based on results with open-label studies, disulfiram is a safe and efficacious treatment compared to other abstinence supportive

    preventivas de identificación de riesgos para la dependencia, control y acompañamiento específicos al grupo de adolescentes dependientes.OBJECTIVE: To identify risk factors for alcohol dependence during adolescence. METHODS: Integrative review of 21 articles published between 2000 and 2009, captured in the LILACS, BVS, MEDLINE, COCHRANE and IBECS databases, with keywords: adolescence, risk for dependence, and alcohol . RESULTS: There is evidence that alcohol is the most consumed drug by adolescents, with initiation between 14 and 16 years. Risk factors for dependency are related to early onset of use, media influence, troubled relationship with parents, use by family member, sexual abuse, domestic violence, low self-esteem, curiosity, and peer pressure, among others. The articles pointed to genetic vulnerability to alcohol dependence and controversies in relation to gender and social class. CONCLUSION: Health services should incorporate preventive strategies for identifying risk for dependency, control and monitoring specific to the group of dependent adolescents.

    Full Text Available Olfaction research deeply renewed the knowledge of the pathophysiological mechanisms involved in various psychopathological states and showed that olfactory deficits might constitute an onset or trait marker in psychiatry. However, while alcohol-dependence is the most wide spread psychiatric disorder and while olfaction might be involved in its development and maintenance, olfactory abilities have been little explored in this population. The central aim of this paper is thus to underline the usefulness of olfaction research in alcohol-dependence. After reviewing the few olfaction studies available, a research agenda will be proposed, identifying the major challenges for future research, and particularly: (1 the identification of the origin, extent and cerebral correlates of olfaction deficits; (2 the links between olfaction and emotional-cognitive deficits, and the use of olfaction to understand the pathomechanisms of alcohol-dependence; (3 the interactions between olfaction and other sensory modalities; (4 the use of olfaction to predict the appearance and intensity of cognitive impairments; (5 the impact of olfaction deficits on everyday life in alcohol-dependence.

    Separation is a central step in the process of stigmatizing persons with mental disorders. We examine whether belief in a continuum of symptoms from mental health to mental illness is associated with less stigmatizing attitudes. In a representative population survey in Germany (n=3642), using case-vignettes of persons suffering from schizophrenia, depression or alcohol dependence, we measured belief in a continuity of symptoms, emotional reactions and desire for social distance related to the person described in the vignette. While 42% of respondents agreed in symptom continuity for depression, this percentage was 26% for schizophrenia and 27% for alcohol dependence. Continuum beliefs were associated in general with more positive emotional reactions and less desire for social distance. This relationship was strongest for schizophrenia, followed by alcohol dependence. Continuum beliefs thus seem to be associated with less stigmatizing attitudes, particularly regarding schizophrenia and alcohol dependence. Educational information on the continuous nature of most psychopathological phenomena could usefully be integrated in anti-stigma messages.

    To identify sequence variants in genes that may have roles in neuronal responses to alcohol, we resequenced the 5′ region of NTRK2 and determined linkage disequilibrium (LD) values, haplotype structure, and performed association analyses using 43 single nucleotide polymorphisms (SNPs) covering the entire NTRK2 region in a Finnish Caucasian sample of 229 alcohol dependent subjects with antisocial personality disorder and 287 healthy controls. Individually, three SNPs were associated with alcohol dependence and alcohol abuse (AD)(P-value from 0.0019 to 0.0059, significance level was set at P ≤ 0.01 corrected for multiple testing), while a common eighteen-locus haplotype within the largest LD block of NTRK2, a 119 kb region containing the 5′ flanking region and exons 1 through 15, was marginally overrepresented in control subjects compared to AD individuals (global P = 0.057). Taken together, these results support a role for the NTRK2 gene in addiction in a Caucasian population with AD and a subtype of antisocial personality disorder. PMID:17200667

    The aim of the present study is to describe and understand the meaning of living with alcohol dependency (AD) as a man. Studies point out a high prevalence of AD in men and the reasons for, and consequences of, that are complex. However, today there is a lack of knowledge about men's lived experiences of having AD. In-depth interviews were conducted with 15 alcohol dependent men and analyzed using a phenomenological-hermeneutic approach. In the comprehensive understanding, findings from the naïve understanding and the structural analysis were interpreted with help from both gender and caring theoretical perspectives. "A Fallible Man" and "A Man with Powerfulness" were disclosed as two main gender formations influencing senses of well-being. A Fallible Man involved varying experiences of restrictions, being in control, and meaninglessness. Being in control promoted a sense of well-being. A Man with Powerfulness involved energetic activity, and the development and maintaining of interests as well as risk-taking. Being powerful diminished feelings of meaninglessness, cravings, and social alienation. The results show, among other things, that the men live an incompatible life and, because of that, need support and guidance to find a more meaningful life. This can be accomplished if caregivers allow men to be in focus and involved in planning their own care. To avoid limiting the men while they are in treatment, the health care professionals also need to focus on the men's everyday life. This focus involves acknowledging the men's individual experiences of what enriches and limits their everyday lives.

    Full Text Available Abstract Background Chronic medical diseases require regular and longitudinal care and self-management for effective treatment. When chronic diseases include substance use disorders, care and treatment of both the medical and addiction disorders may affect access to care and the ability to focus on both conditions. The objective of this paper is to evaluate the association between the presence of chronic medical disease and recent addiction treatment utilization among adults with substance dependence. Methods Cross-sectional secondary data analysis of self-reported baseline data from alcohol and/or drug-dependent adults enrolled in a randomized clinical trial of a disease management program for substance dependence in primary care. The main independent variable was chronic medical disease status, categorized using the Katz Comorbidity Score as none, single condition of lower severity, or higher severity (multiple conditions or single higher severity condition, based on comorbidity scores determined from self-report.

    Research has demonstrated the positive association between alcohol craving and alcohol use and has identified craving as a central component of alcohol use disorders (AUD). Despite potential clinical implications, few studies have examined the relationship between craving and alcohol use in individuals with AUD and common psychiatric comorbidities or explored possible moderators of the craving-alcohol use relationship. The current study used daily monitoring data to: 1) replicate previous findings detecting a positive relationship between craving and alcohol use in individuals with AUD and co-occurring posttraumatic stress disorder (PTSD) and 2) extend these findings by examining the influence of initial change motivation on the craving-use relationship and within-day associations among craving, efforts to control craving, and alcohol consumption. Participants were 84 individuals with alcohol dependence and PTSD enrolled in an intervention study. Generalized estimating equations using pre-treatment baseline daily data revealed significant main effects for craving, craving control, and motivation to change alcohol use. Daily craving was positively related to alcohol use. Greater change motivation and craving control (i.e., efforts to resist craving, avoidance of thoughts and feelings related to craving) were negatively related to alcohol use. A significant interaction was detected between baseline change motivation and daily craving indicating that the association between craving and alcohol use was significantly stronger for those with low baseline change motivation. A significant interaction was also detected between craving control and daily craving, suggesting that participants were more likely to consume alcohol when experiencing high levels of craving if they reported low levels of craving control. Findings bolster the idea that efforts to prevent or ameliorate craving are critical to treatment success for individuals with AUD and PTSD who are seeking to

    Full Text Available Background: To investigate the improvement in quality of life (QoL of alcohol-dependent patients during a 3-week inpatient withdrawal programme, and to identify the sociodemographic, clinical and alcohol-related variables associated with baseline QoL on admission and with improvement of QoL during residential treatment. Methods: This prospective, observational study included 414 alcohol-dependent patients, hospitalised for a period of 3 weeks. QoL was measured on admission and at discharge using the French version of the Medical Outcome Study SF-36. The mean scores for each dimension and for the Physical and Mental Component Summary scores were calculated. Results: The mean scores per dimension and the mean Physical and Mental Component Summary scores were significantly lower on admission than at discharge; the lowest scores being observed for social functioning and role limitations due to emotional problems. At discharge, the mean scores per dimension were similar to those observed in the French general population. Female gender, age >45 years, living alone, working as a labourer or employee, somatic comorbidity, and the existence of at least five criteria for alcohol dependence according to the DSM-IV classification were associated with a low Physical Component Summary score on admission; psychiatric comorbidity, the presence of at least five DSM-IV dependence criteria, smoking and suicidality were associated with a low Mental Component Summary score on admission. The increase in Physical and Mental Component Summary scores during hospitalisation was more marked when the initial scores were low. Apart from the initial score, the greatest improvement in Physical Component Summary score was seen in patients with a high alcohol intake and in those without a somatic comorbidity; the increase in Mental Component Summary score was greatest in patients without psychotic symptoms and in those who abused or were dependent on illegal drugs.

    Background Alcohol dependence (AD) is a serious and common public health problem.The identification of genes that contribute to the AD variation will improve our understanding of the genetic mechanism underlying this complex disease.Previous genome-wide association studies (GWAS) and candidate gene genetic association studies identified individual genes as candidates for alcohol phenotypes,but efforts to generate an integrated view of accumulative genetic variants and pathways under alcohol drinking are lacking.Methods We applied enrichment gene set analysis to existing genetic association results to identify pertinent pathways to AD in this study.A total of 1 438 SNPs (P <1.0×10-3) associated to alcohol drinking related traits have been collected from 31 studies (10 candidate gene association studies,19 GWAS of SNPs,and 2 GWAS of copy number variants).Results Among all of the KEGG pathways,the calcium signaling pathway (hsa04020) showed the most significant enrichment of associations (21 genes) to alcohol consumption phenotypes (P=5.4×10-5).Furthermore,the calcium signaling pathway is the only pathway that turned out to be significant after multiple test adjustments,achieving Bonferroni P value of 0.8×10-3 and FDR value of 0.6×10-2,respectively.Interestingly,the calcium signaling pathway was previously found to be essential to regulate brain function,and genes in this pathway link to a depressive effect of alcohol consumption on the body.Conclusions Our findings,together with previous biological evidence,suggest the importance of gene polymorphisms of calcium signaling pathway to AD susceptibility.Still,further investigations are warranted to uncover the role of this pathway in AD and related traits.

    The expression of dopamine receptor (DRD), Nurr1 transcription factor (NR4A2), and α-sinucleine (SNCA) genes in peripheral blood lymphocytes is evaluated. The results indicate that alcohol dependence is associated with high expression of SNCA and DRD4 (signifi cantly higher than in the control group) and is not associated with changes in the work of NR4A2 and DRD3 genes. The levels of DRD3 and DRD4 mRNA form a positive linear correlation (p≤0.05). The expression of SNCA and DRD4 genes can serve as an important peripheral marker of alcohol dependence development, which is essential for antipsychotic therapy. PMID:26621272

    This article reports two longitudinal prospective studies conducted sequentially to describe participants' maintenance of abstinence experiences up to 36 months posttreatment. Study 1 reports responses of 102 subjects who maintained alcohol abstinence following treatment and who were assessed for duration and intensity of symptoms associated with postacute withdrawal at baseline, 3, 6, and 12 months. A decreasing linear trend of symptoms was found as time of alcohol abstinence increased. Study 2 obtained interview and survey data from 23 successful abstainers from Study 1 at 12, 18, and 36 months posttreatment to describe coping strategies, perceptions of relapse risk, extent and duration of "aftercare," and substitute addictions as these phenomena developed and changed over time. Multiple occasions of data collection supported the description of three phases of maintenance: symptom stabilization/management accompanied by a cognitive paradigm shift, distancing self from alcohol-dependent behavior, and normalization of life processes.

    Biological endophenotypes are more proximal to gene function than psychiatric diagnosis, providing a powerful strategy in searching for genes in psychiatric disorders. These intermediate phenotypes identify both affected and unaffected members of an affected family, including offspring at risk, providing a more direct connection with underlying biological vulnerability. The Collaborative Study on the Genetics of Alcoholism (COGA) has employed heritable neurophysiological features (i.e., brain oscillations) as endophenotypes, making it possible to identify susceptibility genes that may be difficult to detect with diagnosis alone. We found significant linkage and association between brain oscillations and genes involved with inhibitory neural networks (e.g., GABRA2, CHRM2), including frontal networks that are deficient in individuals with alcohol dependence, impulsivity, and related disinhibitory disorders. We reported significant linkage and linkage disequilibrium for the beta frequency of the EEG and GABRA2, a GABAA receptor gene on chromosome 4, which we found is also associated with diagnosis of alcohol dependence and related disorders. More recently, we found significant linkage and association with GABRA2 and interhemispheric theta coherence. We also reported significant linkage and linkage disequilibrium between the theta and delta event-related oscillations underlying P3 to target stimuli and CHRM2, a cholinergic muscarinic receptor gene on chromosome 7, which we found is also associated with diagnosis of alcohol dependence and related disorders. Thus, the identification of genes important for the expression of the endophenotypes (brain oscillations) helps when identifying genes that increase the susceptibility for risk of alcohol dependence and related disorders. These findings underscore the utility of quantitative neurophysiological endophenotypes in the study of the genetics of complex disorders. We will present our recent genetic findings related to

    Alcohol addiction is a chronic relapsing disorder that presents a substantial public health problem, and is frequently co-morbid 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. The present study compares two methods for induction of craving via stress and alcohol cues in individuals with co-morbid 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. Subjects were 52 individuals diagnosed with co-morbid AD and PTSD seeking treatment at the National Institute on Alcohol Abuse and Alcoholism inpatient research facility. They participated in a 4-week inpatient study of the efficacy of a neurokinin 1 antagonist to treat co-morbid AD and PTSD, and which included the two challenge procedures. 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 adrenocorticotropic hormone and cortisol, while the Scripts did not. 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 versus alcohol cues, as well as to understand the impact of co-morbid PTSD and AD on craving.

    Alcohol dependence is associated with a dysregulated dopamine system modulating reward, craving and cognition. The monoamine stabilizer (-)-OSU6162 (OSU6162) can counteract both hyper- and hypo-dopaminergic states and we recently demonstrated that it attenuates alcohol-mediated behaviors in long-term drinking rats. The present Phase II exploratory human laboratory study investigated to our knowledge for the first time the effects of OSU6162 on cue- and priming-induced craving in alcohol dependent individuals. Fifty-six alcohol dependent individuals were randomized to a 14-day-treatment period of OSU6162 or placebo after their baseline impulsivity levels had been determined using the Stop Signal Task. On Day 15, participants were subjected to a laboratory alcohol craving test comprised of craving sessions induced by: i) active - alcohol specific cues, ii) neutral stimuli and iii) priming - intake of an alcoholic beverage (0.20g ethanol/kg bodyweight). Subjective ratings of alcohol craving were assessed using the shortened version of the Desire for Alcohol Questionnaire and visual analog scales (VAS). OSU6162 treatment had no significant effect on cue-induced alcohol craving, but significantly attenuated priming-induced craving. Exploratory analysis revealed that this effect was driven by the individuals with high baseline impulsivity. In addition, OSU6162 significantly blunted the subjective liking of the consumed alcohol (VAS). Although the present 14-day-treatment period, showed that OSU6162 was safe and well tolerated, this exploratory human laboratory study was not designed to evaluate the efficacy of OSU6162 to affect alcohol consumption. Thus a larger placebo-controlled efficacyclinical trial is needed to further investigate the potential of OSU6162 as a novel medication for alcohol dependence.

    Full Text Available Aim: To assess personality disorder (PD, emotional intelligence (EI, and locus of control of alcohol dependent (AD patients and its comparison with normal controls. Materials and Methods: Based on purposive sampling technique, 33 AD patients were selected from the De-Addiction Ward of Ranchi Institute of Neuro-Psychiatry and Allied Sciences (RINPAS and 33 matched normal subjects were selected from Ranchi and nearby places. Both the groups were matched on various sociodemographic parameters, that is, age, gender, and socioeconomic level. All participants were assessed with Millon Clinical Multiaxial Inventory-III, Mangal EI Inventory, and Locus of Control scale. Obtained responses were scored by using standard scoring procedures and subsequently statistically analyzed by using Chi-square test. Results: AD patients have more comorbid pathological personality traits and disorders in comparison to their normal counterparts. Depressive, narcissistic, and paranoid PDs were prominent among AD group; followed by schizotypal, antisocial, negativistic, dependent, schizoid, sadistic, masochistic, and borderline PD. In comparison to normal participants, AD patients were significantly deficient in almost all the areas of EI and their locus of control was externally oriented. Conclusion: Patients with AD have significantly higher PDs, low EI, and an external orientation on the locus of control. Identification and management of these comorbid conditions are likely to improve the management and outcome of AD.

    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.

    Emotional visual perception deficits constitute a major problem in alcohol-dependence. Indeed, the ability to assess the affective content of external cues is a key adaptive function, as it allows on the one hand the processing of potentially threatening or advantageous stimuli, and on the other hand the establishment of appropriate social interactions (by enabling rapid decoding of the affective state of others from their facial expressions).

We collected data from a representative sample of community participants (N = 1,630; ages 54 – 65 years) and their informants (N = 1,462). Measures employed were the substance use disorder sections...

  19. Are visual impairments responsible for emotion decoding deficits in alcohol-dependence?

    Full Text Available Emotional visual perception deficits constitute a major problem in alcohol-dependence. Indeed, the ability to assess the affective content of external cues is a key adaptive function, as it allows on the one hand the processing of potentially threatening or advantageous stimuli, and on the other hand the establishment of appropriate social interactions (by enabling rapid decoding of the affective state of others from their facial expressions. While such deficits have been classically considered as reflecting a genuine emotion decoding impairment in alcohol-dependence, converging evidence suggests that underlying visual deficits might play a role in emotional alterations. This hypothesis appears to be relevant especially as data from healthy populations indicate that a coarse but fast analysis of visual inputs would allow emotional processing to arise from early stages of perception. After reviewing those findings and the associated models, the present paper underlines data showing that rapid interactions between emotion and vision could be impaired in alcohol-dependence and provides new research avenues that may ultimately offer a better understanding of the roots of emotional deficits in this pathological state.

    Full Text Available Introduction: Beta-galactosidase (GAL is a lysosomal exoglycosidase involved in the catabolism of glycoconjugates through the sequential release of beta-linked terminal galactosyl residues. The stimulation of activity of exoglycosidases and other degradative enzymes has been noted in cancers as well as in alcohol and nicotine addiction separately. This is the first study to evaluate the activity of the serum senescence marker GAL in colon cancer patients with a history of alcohol and nicotine dependence, as a potential factor of worse cancer prognosis.Material and Methods: The material was serum of 18 colon cancer patients and 10 healthy volunteers. Ten colon cancer patients met alcohol and nicotine dependence criteria. The activity of beta-galactosidase (pkat/ml was determined by the colorimetric method. Comparisons between groups were made using the Kruskal-Wallis analysis and differences evaluated using the Mann-Whitney U test. Spearman’s rank correlation coefficient was used to measure the statistical dependence between two variables.Results: The activity of serum GAL was significantly higher in colon cancer patients with a history of alcohol and nicotine dependence, in comparison to colon cancer patients without a history of drinking/smoking (p=0.015; 46�0increase, and the controls (p=0.0002; 81�0increase. The activity of serum GAL in colon cancer patients without a history of alcohol/nicotine dependence was higher than the activity in the controls (p = 0.043; 24�0increase.Discussion/Conclusion: Higher activity of beta-galactosidase may potentially reflect the accelerated growth of the cancer, invasion, metastases, and maturation, when alcohol and nicotine dependence coincide with colon cancer. For a better prognosis of colon cancer, alcohol and nicotine withdrawal seems to be required.

  1. A randomised controlled trial of extended brief intervention for alcohol dependent patients in an acute hospital setting (ADPAC

    Full Text Available Abstract Background Alcohol dependence affects approximately 3% of the English population, and accounts for significant medical and psychiatric morbidity. Only 5.6% of alcohol-dependent individuals ever access specialist treatment and only a small percentage ever seek treatment. As people who are alcohol dependent are more likely to have experienced health problems leading to frequent attendance at acute hospitals it would seem both sensible and practical to ensure that this setting is utilised as a major access point for treatment, and to test the effectiveness of these treatments. Methods/Design This is a randomised controlled trial with a primary hypothesis that extended brief interventions (EBI delivered to alcohol-dependent patients in a hospital setting by an Alcohol Specialist Nurse (ASN will be effective when compared to usual care in reducing overall alcohol consumption and improving on the standard measures of alcohol dependence. Consecutive patients will be screened for alcohol misuse in the Emergency Department (ED of a district general hospital. On identification of an alcohol-related problem, following informed written consent, we aim to randomize 130 patients per group. The ASN will discharge to usual clinical care all control group patients, and plan a programme of EBI for treatment group patients. Follow-up interview will be undertaken by a researcher blinded to the intervention at 12 and 24 weeks. The primary outcome measure is level of alcohol dependence as determined by the Severity of Alcohol Dependence Questionnaire (SADQ score. Secondary outcome measures include; Alcohol Use Disorders Identification Test (AUDIT score, quantity and frequency of alcohol consumption, health-related quality of life measures, service utilisation, and patient experience. The trial will also allow an assessment of the cost-effectiveness of EBI in an acute hospital setting. In addition, patient experience will be assessed using qualitative methods

    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.

    Two-part random effects models (Olsen and Schafer,(1) Tooze et al.(2)) have been applied to repeated measures of semi-continuous data, characterized by a mixture of a substantial proportion of zero values and a skewed distribution of positive values. In the original formulation of this model, the natural logarithm of the positive values is assumed to follow a normal distribution with a constant variance parameter. In this article, we review and consider three extensions of this model, allowing the positive values to follow (a) a generalized gamma distribution, (b) a log-skew-normal distribution, and (c) a normal distribution after the Box-Cox transformation. We allow for the possibility of heteroscedasticity. Maximum likelihood estimation is shown to be conveniently implemented in SAS Proc NLMIXED. The performance of the methods is compared through applications to daily drinking records in a secondary data analysis from a randomized controlled trial of topiramate for alcohol dependence treatment. We find that all three models provide a significantly better fit than the log-normal model, and there exists strong evidence for heteroscedasticity. We also compare the three models by the likelihood ratio tests for non-nested hypotheses (Vuong(3)). The results suggest that the generalized gamma distribution provides the best fit, though no statistically significant differences are found in pairwise model comparisons.

    Full Text Available Abstract Background Alcohol dependence comorbid with major depressive disorder poses a major challenge in the clinical setting. The results in the treatment with selective serotonin re-uptake inhibitors have been conflicting. Thus, we compared in alcohol-dependent patients with co-morbid major depressive disorder the selective serotonin re-uptake inhibitor escitalopram to a compound that acts on different transporter system and may reduce craving, the glutamate receptor antagonist memantine. Methods Eighty alcohol-dependent patients comorbid with major depressive disorder in municipal alcohol clinics were randomized 1:1 to receive memantine 20 mg or escitalopram 20 mg in a double-blind manner. During the 26-week study period patients continued their routine treatment at the clinics. Abstinence was not required but encouraged. The patients attended visits weekly during the first month, and then at 3 and at 6 months. Outcome measures were Alcohol Use Disorders Identification Test (AUDIT, Obsessive Compulsive Drinking Scale (OCDS and Drinking Diary. Results The completion rate was high in both groups, especially among the patients who had been abstinent at the beginning of the study. However, among those patients who were not abstinent at baseline, 47% in both groups discontinued the study. Numbers of abstinent days were high in both groups throughout the study. Alcohol consumption measured by the AUDIT QF (quantity-frequency score was significantly reduced in both groups, as was the craving for alcohol measured by the OCDS. Early age at first alcohol intoxication predicted poor treatment outcomes in patients treated with escitalopram, and the same was seen with the early onset of the first depressive episode. The same predictive effects were not found in patients treated with memantine. Conclusion Our results indicate that both memantine and escitalopram are useful adjunct medications for the treatment of alcohol dependence co-morbid with major

    Background and Aims 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. Methods 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). Results 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. Discussion 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. PMID:26690622

    Full Text Available Objective: In this study, it is aimed to evaluate the validity and reliability of the Beliefs About Substance Use Questionnaire (BSU which was originally developed by Wright (1993. Method: Seventy alcohol addicted inpatients, who were admitted to Ankara Dışkapı Yıldırım Beyazıt Education and Research Hospital Psychiatry Clinic, 31 healthy volunteers who had never used alcohol and 33 social drinkers were evaluated. For all groups, BSU and Craving Beliefs Questionnaire (CBQ, for the patient groups, Beck Anxiety Inventory (BAI, Clinical Institute Withdrawal Assessment (CIWA, Dysfunctional Attitudes Questionnaire (DAS and Automatic Thoughts Questionnaire (ATQ were used as the assessment tools. The correlations and differences between the questionnaires were studied. Results: Mean age of the addicted patients, healthy controls and social drinkers were 42,3± 7,0, 33,5± 9,9 and 33,2± 8,9, respectively. In patient group, mean BSU score was 46,4 ± 21,2. For alcohol addicts, internal reliability of BSU was found to be adequate (Cronbach alfa=0.91 and item-total score correlations were between 0.33 and 0.69. Basic component analysis showed one basic factor. A positive correlation has been found between BSU and CBQ, and ATQ scores. No correlations have been found between total and subscale scores of DAS and total scores of CIWA, BAI and BSU. In evaluation of validity, BSU mean scores of alcohol addicts were found to be significantly higher than healthy controls and social drinkers. Conclusion: Our findings support that Turkish version of BSU is an adequate tool that can be used to evaluate alcohol addicted patients` cognitive believes about alcohol use

  14. Dendritic spine changes in the development of alcohol addiction regulated by α-calcium/calmodulin-dependent protein kinase II

    Full Text Available Introduction Alcohol has many adverse effects on the brain. Among them are dendritic spine morphology alterations, which are believed to be the basis of alcohol addiction. Autophosphorylation of α-calcium/calmodulin-dependent protein kinase II (αCaMKII has been shown to regulate spine morphology in vitro. Here we show that αCaMKII can also regulate addiction related behaviour and dendritic spine morphology changes caused by alcohol consumption in vivo. Method 12 αCaMKII-autophosphorylation deficient female mice (T286A and 12 wild type littermates were used in the study. T286A strain was created by Giese et al. (1998. Mice were housed and tested in two IntelliCages from NewBehavior (www.newbehavior.com. IntelliCage is an automated learning system. After 95 days of alcohol drinking interrupted by tests for motivation, persistence in alcohol seeking and probability of relapse, mice were ascribed to ‘high’ or ‘low’ drinkers group according to their performance in the tests. Additional criterion was the amount of alcohol consumed during the whole experiment. Result of each test was evaluated separately. 1/3 of the mice that scored highest in each criterion were considered ‘positive’ for this trait. ‘Positive’ animals were given 1 point, negative 0 points. Mice that were positive in at least 2 criteria were ascribed to ‘high’ drinkers (‘+’ group. Remaining mice – to ‘low’ drinkers (‘–‘. This method of behavioral phenotyping, developed by Radwanska and Kaczmarek (2012, is inspired by DSM-IV. Since the results of this evaluation are discrete (i.e. by definition all the animals score between 0 to +4, we developed also a continuous method of addiction rating, which we call ‘addiction index’. The result of the second method is a sum of the standardized (z-score results of the above mentioned tests. We use it to examine the correlations between addiction-like behavior and spine parameters.

    The alcohol dependence section of the Mini International Neuropsychiatric Interview questionnaire (MINI) has not been evaluated in young Africans. We applied the MINI in a cross-sectional study of 202 alcohol users from northern-Tanzania, aged 18-24 years (103 male casual workers and 99 students), and validated it against phophatidylethanol (PEth) at a cut-off suggesting heavy chronic alcohol use (≥0.30 µmol/L). Blood was assayed for PEth (16:0/18:1-subform) by liquid chromatography-tandem mass spectrometry. The MINI dependence criteria (≥3 positive responses) were met by 39% participants although their PEth levels were low. Contrary, many young people with high PEth levels were not classified as dependent. The sensitivity of the MINI ranged from 0% to 69% (female students and male workers, respectively) and specificity from 52% to 85% (workers and female students, respectively). The highest AUROC (0.68) occurred with a cut-off of ≥4 positive responses. A modified MINI with three affirmative responses to five questions increased specificity to 92%-97%; however, sensitivity remained low. The performance of the MINI in detecting dependence among young people from northern-Tanzania is unsatisfactory. Specificity was improved using a modified version but sensitivity remained low. An accurate tool for the diagnosis of alcohol dependence is needed for epidemiological and clinical purposes. PMID:26529004

    Studies show high rates of co-morbid post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) but there is no consensus on the causal direction of the relationship. Some theories suggest AUD develops as a coping mechanism to manage PTSD symptoms and others that AUD is a vulnerability factor for PTSD. A third hypothesis posits independent developmental pathways stemming from a shared etiology, such as the trauma exposure itself. We examined these hypotheses using longitudinal data on 922 National Guard soldiers, representing a subsample (56%) of a larger pre- and post-deployment cross-sectional study of New Jersey National Guard soldiers deployed to Iraq. Measures included the PTSD Checklist (PCL), DSM-IV-based measures of alcohol use/misuse from the National Household Survey of Drug Use and Health and other concurrent mental health, military and demographic measures. Results showed no effect of pre-deployment alcohol status on subsequent positive screens for new onset PTSD. However, in multivariate models, baseline PTSD symptoms significantly increased the risk of screening positive for new onset alcohol dependence (AD), which rose 5% with each unit increase in PCL score (AOR = 1.05; 95% CI = 1.02-1.07). Results also supported the shared etiology hypothesis, with the risk of a positive screen for AD increasing by 9% for every unit increase in combat exposure after controlling for baseline PTSD status (AOR = 1.09; 95% CI = 1.03-1.15) and, in a subsample with PCL scores <34, by 17% for each unit increase in exposure (AOR = 1.17; 95% CI = 1.05-1.31). These findings have implications for prevention, treatment and compensation policies governing co-morbidity in military veterans.

    The central element of the "qualified withdrawal treatment" of alcohol dependence is - in addition to physical withdrawal treatment - psychotherapy. The treatment of the underlying addictive disorder that is displayed by intoxication, harmful behaviour and withdrawal symptoms is only possible with a combination of somatic and psychotherapeutic treatment elements. The successfully established multimodal therapy of the "qualified alcohol withdrawal treatment", postulated in the current S3-Treatment Guidelines, requires a multi-disciplinary treatment team with psychotherapeutic competence. The aim of the present work is to calculate the normative staff requirement of a guideline-based 21-day qualified withdrawal treatment and to compare the result with the staffing regulations of the German Institute for Hospital Reimbursement. The present data support the hypothesis that even in the case of a hundred per cent implementation of these data, adequate therapy of alcohol-related disorders, according to the guidelines, is not feasible. This has to be considered when further developing the finance compensation system based on the described superseded elements of the German Institute for Hospital Reimbursement. PMID:26842899

    Full Text Available The author briefly interprets the research – results, referring to the phenomenon of children of alcoholics, especially the psychological and psychopathological characteristics of children of alcoholics in adolescence and young adulthood. The author presents a screening study of adolescents. The sample contains 200 high school students at age 18. The aim of the survey was to discover the relationship between alcohol consumption of parents, PTSD - related psychopathological symptoms and reported life quality of their children. The study confirmed the hypothesis about a substantial correlation between high alcohol consumption of parents, higher psychopathological symptom - expression and lower reported life quality score of their children. Higher PTSD-related symptomatology in children of alcoholics is probably resulted by home violence, which is very often present in family of alcoholics. The article also evaluated the results regarding suicide ideation of children of alcoholics, which is definitely more frequent and more intense than in their peers living in non alcoholdependent families.

    Riding a motorcycle under the influence of alcohol is a dangerous activity, especially considering the high vulnerability of motorcyclists. The present research investigates the factors that affect the declared frequency of drink-riding among motorcyclists in Europe and explores regional differences. Data were collected from the SARTRE-4 (Social Attitudes to Road Traffic Risk in Europe) survey, which was conducted in 19 countries. A total sample of 4483 motorcyclists was interviewed by using a face-to-face questionnaire. The data were analyzed by means of multilevel ordered logit models. The results revealed significant regional differences (between Northern, Eastern and Southern European countries) in drink-riding frequencies in Europe. In general, declared drinking and riding were positively associated with gender (males), increased exposure, underestimation of risk, friends' behaviour, past accidents and alcohol ticket experience. On the other hand, it was negatively associated with underestimation of the amount of alcohol allowed before driving, and support for more severe penalties.

Data were collected from the SARTRE-4 (Social Attitudes to Road Traffic Risk in Europe) survey, which was conducted in 19 countries. A total sample of 4483 motorcyclists was interviewed by using a face-to-face questionnaire. The data were analyzed by means of multilevel ordered logit models. The results revealed significant regional differences (between Northern, Eastern and Southern European countries) in drink-riding frequencies in Europe. In general, declared drinking and riding were positively associated with gender (males), increased exposure, underestimation of risk, friends' behaviour, past accidents and alcohol ticket experience. On the other hand, it was negatively associated with underestimation of the amount of alcohol allowed before driving, and support for more severe penalties. PMID:24713220

    Alcohol dependence (AD) is an important contributory factor to the global burden of disease. The etiology of AD involves both environmental and genetic factors, and the disorder has a heritability of around 50%. The aim of the present study was to identify susceptibility genes for AD by performing a genome-wide association study (GWAS). The sample comprised 1333 male in-patients with severe AD according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and 2168 controls. These included 487 patients and 1358 controls from a previous GWAS study by our group. All individuals were of German descent. Single-marker tests and a polygenic score-based analysis to assess the combined contribution of multiple markers with small effects were performed. The single nucleotide polymorphism (SNP) rs1789891, which is located between the ADH1B and ADH1C genes, achieved genome-wide significance [P = 1.27E-8, odds ratio (OR) = 1.46]. Other markers from this region were also associated with AD, and conditional analyses indicated that these made a partially independent contribution. The SNP rs1789891 is in complete linkage disequilibrium with the functional Arg272Gln variant (P = 1.24E-7, OR = 1.31) of the ADH1C gene, which has been reported to modify the rate of ethanol oxidation to acetaldehyde in vitro. A polygenic score-based approach produced a significant result (P = 9.66E-9). This is the first GWAS of AD to provide genome-wide significant support for the role of the ADH gene cluster and to suggest a polygenic component to the etiology of AD. The latter result may indicate that many more AD susceptibility genes still await identification.

  5. A case report on varenicline induced delirium in an alcohol and nicotine dependent patient

    Full Text Available Varenicline is a smoking cessation agent. Varenicline acts as a partial agonist of α4β2 neuronal nicotinic acetylcholine receptor and prevents nicotine binding to the same. It also causes dopamine (DA stimulation that decreases craving and symptoms of dependence. A 40-year-old male diagnosed with alcohol and nicotine dependence syndrome was treated with 1 mg of varenicline for 3 days. Patient developed episodes of transient delirium within 15-30 min after administration of varenicline. Patient was disoriented and did not respond relevantly. Patient would have disorientation and would respond irrelevantly and was unable to recall the event completely. There were no features suggestive of seizures. The episodes resolved after the medication was stopped. Varenicline, with its partial agonistic effect on nicotinergic receptors, stimulates the release of multiple neurotransmitters including DA. DA dysregulation is probably responsible for the development of neuropsychiatric adverse reactions due to varenicline. This is the first case report to the best of our knowledge reporting varenicline induced dilirium. In this case, the adverse event was found in an alcohol and nicotine dependent patient undergoing treatment. It is essential to monitor uncommon adverse effects as this can cause significant morbidity.

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

    Full Text Available Cross-modal 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 cross-modal 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 cross-modal processes in psychiatry. We will illustrate this proposal by means of the recent data obtained in the cross-modal 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 cross-modal 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 cross-modal 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.

    Full Text Available Abstract Background This study investigates the relationship between parental drinking and school adjustment in a total population sample of adolescents, with independent reports from mothers, fathers, and adolescents. As a group, children of alcohol abusers have previously been found to exhibit lowered academic achievement. However, few studies address which parts of school adjustment that may be impaired. Both a genetic approach and social strains predict elevated problem scores in these children. Previous research has had limitations such as only recruiting cases from clinics, relying on single responders for all measures, or incomplete control for comorbid psychopathology. The specific effects of maternal and paternal alcohol use are also understudied. Methods In a Norwegian county, 88% of the population aged 13-19 years participated in a health survey (N = 8984. Among other variables, adolescents reported on four dimensions of school adjustment, while mothers and fathers reported their own drinking behaviour. Mental distress and other control variables were adjusted for. Multivariate analysis including generalized estimation equations was applied to investigate associations. Results Compared to children of light drinkers, children of alcohol abusers had moderately elevated attention and conduct problem scores. Maternal alcohol abuse was particularly predictive of such problems. Children of abstainers did significantly better than children of light drinkers. Controlling for adolescent mental distress reduced the association between maternal abuse and attention problems. The associations between parental reported drinking and school adjustment were further reduced when controlling for the children's report of seeing their parents drunk, which itself predicted school adjustment. Controlling for parental mental distress did not reduce the associations. Conclusions Parental alcohol abuse is an independent risk factor for attention and conduct

    酒精依赖是一种常见的精神疾病,社会危害大,疾病负担重。目前致力于酒精依赖的预防和治疗的研究取得的成果比较有限。为了进一步完善酒精依赖的治疗和预防措施,有必要对酒精依赖潜在的生物学机制进行深入探究。迄今为止,针对酒精依赖错综复杂的病因学的研究,大部分聚焦于多巴胺系统的关键作用。本综述总结了目前国内外对饮酒行为与多巴胺能系统之间关系的研究,发现研究结果并不一致,甚至相互矛盾,可能是由于方法学的差异、非线性的剂量效应、样本的选取差异以及多巴胺系统与其它神经递质系统之间可能存在交互作用等因素造成。%Summary:Alcohol dependence is a common mental disorder that is associated with substantial disease burden. Current efforts at preveniton and treatment of alcohol dependence are of very limited effecitveness. A better understanding of the biological mechanisms underlying dependence is essenital to improving the outcomes of treatment and preveniton iniitaitves. To date, most of the efforts have focused on the key role of the dopamine system in the complex eitological network of alcohol dependence. This review summarizes current research about the relaitonships between alcohol consumpiton and the dopaminergic system. We ifnd that many of the currently available studies have contradictory results, presumably due to differences in methodology, non-linear dosage effects, use of different samples, and the possible confounding effects of other neurotransmitter systems.

  11. [Sexual addiction in alcohol abuse and dependence. Clinical, nosologic and psychoanalytic aspects].

    Science.gov (United States)

    Roth, K

    1992-03-01

    DSM-III-R names sexual addiction for the first time as a sexual disorder. In this study a group of alcoholics was examined who described their own sexual behavior as being addictive and self-destructive. In this nearly all male patient group sexual addiction manifested itself mostly in excessive masturbation and obsessional sexual fantasies often in combination with use of pornography. Promiscuity, prostitute contacts and excessive sexual demands on a steady partner and sexually deviant behavior, were less often reported in this population. The addictive sexual behavior was said to be usually provoked by emotional distress and unresolved conflicts. More than 80% of these patients were dependent upon at least one other substance beside alcohol. Two-thirds considered their sexual addictive behavior to be their primary and earliest dependency. The nosology of this disorder seems to be unspecific, since a number of forms of neurosis and personality disorder are diagnosed. A psychodynamic interpretation of sexual addiction points to defence mechanisms against inner psychic conflicts, as seen both in addiction and sexual perversion. Aspects of differential diagnosis and classification are also discussed. PMID:1579173

In the present paper, we provide some complements to the recent systematic literature review published by Donadon and de Lima Osório on this crucial topic. We also suggest research avenues that must be, in our opinion, considered in the coming years. More precisely, we propose, first, that a battery integrating a set of emotional tasks relating to different processes should be developed to better systemize EFE decoding measures in alcohol-dependence. Second, we propose to go below EFE recognition deficits and to seek for the roots of those alterations, particularly by investigating the putative role played by early visual processing and vision–emotion interactions in the emotional impairment observed in alcohol-dependence. Third, we insist on the need to go beyond EFE recognition deficits by suggesting that they only constitute a part of wider emotional deficits in alcohol-dependence. Importantly, since the efficient decoding of emotions is a crucial ability for the development and maintenance of satisfactory interpersonal relationships, we suggest that disruption of this ability in alcohol-dependent individuals may have adverse consequences for their social integration. One way to achieve this research agenda would be to develop the field of affective and social neuroscience of alcohol-dependence, which could ultimately lead to major advances at both theoretical

    Full Text Available 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.

  15. Neuronal extracellular signal-regulated kinase (ERK activity as marker and mediator of alcohol and opioid dependence

    Directory of Open Access Journals (Sweden)

    Eva R. Zamora-Martinez

    2014-03-01

    Full Text Available Early pioneering work in the field of biochemistry identified phosphorylation as a crucial post-translational modification of proteins with the ability to both indicate and arbitrate complex physiological processes. More recent investigations have functionally linked phosphorylation of extracellular signal-regulated kinase (ERK to a variety of neurophysiological mechanisms ranging from acute neurotransmitter action to long-term gene expression. ERK phosphorylation serves as an intracellular bridging mechanism that facilitates neuronal communication and plasticity. Drugs of abuse, including alcohol and opioids, act as artificial yet powerful rewards that impinge upon natural reinforcement processes critical for survival. The graded progression from initial exposure to addiction (or substance dependence is believed to result from drug- and drug context-induced adaptations in neuronal signaling processes across brain reward and stress circuits following excessive drug use. In this regard, commonly abused drugs as well as drug-associated experiences are capable of modifying the phosphorylation of ERK within central reinforcement systems. In addition, chronic drug and alcohol exposure may drive ERK-regulated epigenetic and structural alterations that underlie a long-term propensity for escalating drug use. Under the influence of such a neurobiological vulnerability, encountering drug-associated cues and contexts can produce subsequent alterations in ERK signaling that drive relapse to drug and alcohol seeking. Current studies are determining precisely which molecular and regional ERK phosphorylation-associated events contribute to the addiction process, as well as which neuroadaptations need to be targeted in order to return dependent individuals to a healthy state.

  16. Neurosteroid Binding Sites on the GABAA Receptor Complex as Novel Targets for Therapeutics to Reduce Alcohol Abuse and Dependence

    Directory of Open Access Journals (Sweden)

    Mary W. Hulin

    2011-01-01

    Full Text Available Despite the prevalence of alcohol abuse and dependence in the US and Europe, there are only five approved pharmacotherapies for alcohol dependence. Moreover, these pharmacotherapeutic options have limited clinical utility. The purpose of this paper is to present pertinent literature suggesting that both alcohol and the neurosteroids interact at the GABAA receptor complex and that the neurosteroid sites on this receptor complex could serve as new targets for the development of novel therapeutics for alcohol abuse. This paper will also present data collected by our laboratory showing that one neurosteroid in particular, dehydroepiandrosterone (DHEA, decreases ethanol intake in rats under a variety of conditions. In the process, we will also mention relevant studies from the literature suggesting that both particular subtypes and subunits of the GABAA receptor play an important role in mediating the interaction of neurosteroids and ethanol.

    The purpose of the present study was to identify child and adult correlates that differentiate (a) individuals with persistent alcohol dependence from individuals with developmentally-limited alcohol dependence and (b) individuals with adult-onset alcohol dependence from individuals who never diagnose. Participants are 1,037 members of the Dunedin longitudinal study, a birth cohort followed prospectively from birth until age 32. Past-year DSM-IV alcohol dependence diagnoses were ascertained with structured diagnostic interviews at ages 18, 21, 26, and 32. Individuals were classified as developmentally-limited, persistent, or adult-onset subtypes based on their time-ordered pattern of diagnoses. The persistent subtype generally exhibited the worst scores on all correlates, including family psychiatric history, adolescent and adult externalizing and internalizing problems, adolescent and adult substance use, adult quality of life, and coping strategies. The prospective predictors that distinguished them from the developmentally-limited subtype involved family liability, adolescent negative affectivity, daily alcohol use, and frequent marijuana use. Furthermore, young people who developed the persistent subtype of alcohol dependence were distinguished from the developmentally-limited subtype by an inability to reduce drinking and by continued use despite problems, already by age 18. The adult-onset group members were virtually indistinguishable from ordinary cohort members as children or adolescents, but, in adulthood, adult-onset cases were distinguished by problems with depression, substance use, stress, and strategies for coping with stress. Information about age-of-onset and developmental course is fundamental for identifying subtypes of alcohol dependence. Subtype-specific etiologies point to targeted prevention and intervention efforts based on characteristics of each subtype. PMID:23880392

    Full Text Available BACKGROUND AND METHODOLOGY: A low ankle-to-brachial index (ABI is a strong correlate of cardiovascular disease and subsequent mortality. The relationship between ABI and alcohol consumption remains unclear. Data are from the Cardiovascular Risk Survey (CRS, a multiple-ethnic, community-based, cross-sectional study of 14,618 Chinese people (5757 Hans, 4767 Uygurs, and 4094 Kazakhs aged 35 years and over at baseline from Oct. 2007 to March 2010. The relationship between alcohol intake and ABI was determined by use of analysis of covariance and multivariable regressions. PRINCIPAL FINDINGS: In men, alcohol consumption was significantly associated with ABI (P60.0 g/d [OR = 3.857, (95% CI: 2.555-5.824; OR = 2.797, (95% CI: 1.106-3.129; OR = 2.878, (95% CI: 1.215-4.018; respectively] and was significantly lower in men who consumed 20.1-40.0 g/d [OR= 0.330, (95% CI: 0.181-0.599; OR = 0.484, (95% CI: 0.065-0.894; OR = 0.478, (95% CI: 0.243-1.534; respectively] and 40.1-60.0 g/d [OR= 0.306, (95% CI: 0.096-0.969; OR = 0.267, (95% CI: 0.087-0.886; OR = 0.203, (95% CI: 0.113-0.754; respectively] compared with never drinking, respectively (all P0.05 in women. Similarly, PAD was not correlated with alcohol intake in women (all P>0.05. CONCLUSIONS/SIGNIFICANCE: Our results indicated that in Chinese men, alcohol consumption was associated with peripheral artery disease, and consumption of less than 60 g/d had an inverse association with peripheral atherosclerosis whereas consumption of 60 g/d or more had a positive association.

    We developed a novel Pareto regression model with an unknown shape parameter to analyze extreme drinking in patients with Alcohol Dependence (AD). We used the generalized linear model (GLM) framework and the log-link to include the covariate information through the scale parameter of the generalized Pareto distribution. We proposed a Bayesian method based on Ridge prior and Zellner's g-prior for the regression coefficients. Simulation study indicated that the proposed Bayesian method performs better than the existing likelihood-based inference for the Pareto regression.We examined two issues of importance in the study of AD. First, we tested whether a single nucleotide polymorphism within GABRA2 gene, which encodes a subunit of the GABA(A) receptor, and that has been associated with AD, influences 'extreme' alcohol intake and second, the efficacy of three psychotherapies for alcoholism in treating extreme drinking behavior. We found an association between extreme drinking behavior and GABRA2. We also found that, at baseline, men with a high-risk GABRA2 allele had a significantly higher probability of extreme drinking than men with no high-risk allele. However, men with a high-risk allele responded to the therapy better than those with two copies of the low-risk allele. Women with high-risk alleles also responded to the therapy better than those with two copies of the low-risk allele, while women who received the cognitive behavioral therapy had better outcomes than those receiving either of the other two therapies. Among men, motivational enhancement therapy was the best for the treatment of the extreme drinking behavior.

    2013-06-01

    Full Text Available The development of alcohol dependence involves elevated anxiety, low mood, and increased sensitivity to stress, collectively labeled negative affect. Particularly interesting is the recent accumulating evidence that sensitized extrahypothalamic stress systems (e.g., hyperglutamatergic activity, blunted hypothalamic-pituitary-adrenal [HPA] hormonal levels, altered corticotropin-releasing factor signaling, and altered glucocorticoid receptor signaling in the extended amygdala are evident in withdrawn dependent rats, supporting the hypothesis that pathological neuroadaptations in the extended amygdala contribute to the negative affective state. Notably, hippocampal neurotoxicity observed as aberrant dentate gyrus (DG neurogenesis (neurogenesis is a process where neural stem cells in the adult hippocampal subgranular zone generate DG granule cell neurons and DG neurodegeneration are observed in withdrawn dependent rats. These correlations between withdrawal and aberrant neurogenesis in dependent rats suggest that alterations in the DG could be hypothesized to be due to compromised HPA axis activity and associated hyperglutamatergic activity originating from the basolateral amygdala in withdrawn dependent rats. This review discusses a possible link between the neuroadaptations in the extended amygdala stress systems and the resulting pathological plasticity that could facilitate recruitment of new emotional memory circuits in the hippocampus as a function of aberrant DG neurogenesis.

    Full Text Available Background The results of numerous studies indicate strong associations of personality with the occurrence, and also with the treatment, of alcohol dependence. However, there is no agreement regarding the role of particular dimensions of temperament and character in the course of, and for the results of, alcohol rehabilitation therapy. The objective of the present research was to investigate the relationships between the dimensions of temperament and character as they are presented by Robert Cloninger and motivation for maintaining abstinence in the case of male alcohol-dependent individuals concluding the therapy. Participants and procedure Eighty-nine male alcohol-dependent individuals, concluding alcohol rehabilitation therapy in an outpatient setting, were studied. The following research tools were applied: the Temperament and Character Inventory (TCI of R. Clo­ninger in the Polish adaptation of E. Hornowska (2003, and the Motivation for Maintaining Abstinence Inventory, the author of which is M. Ziółkowski. Results Two clusters, differing in the aspect of motivation for maintaining abstinence after the conclusion of the treatment, were distinguished: of individuals manifesting weaker motivation (n = 39 and those manifesting stronger motivation (n = 50. The patients with stronger motivation manifested the following major features: a lower level of harm avoidance, a higher level of reward dependence, and a higher level of cooperativeness. Conclusions Personality as it is presented by Cloninger manifests connections with motivation for maintaining abstinence. The research confirms the need for diagnosing addicted patients in the scope of temperament and character traits.

    Full Text Available Objective: To demonstrate the usefulness of the Addiction Severity Index Japanese Version (ASI-J in Japanese alcohol-dependent individuals. The ASI is a frequently used clinical and research instrument that measures severities in seven functional domains in people with substance abuse disorders. Methods: A total of 370 male inpatients with a history of alcohol dependence participated in the study. Forty-nine participants were excluded in the final analysis due to lack of reliability (i.e., patient misrepresentation or inability to understand. We used the ASI-J and a series of indexes that determined patient states during and post-treatment. Results: The correlations between ASI Composite Scores (CSs, which were calculated through a weighted formula and indicated the severity of each problem area, were significant but low in eight relations and not significant in 13 relations, indicating substantial independence of the problem areas. Significant differences were found in Family/Social CSs between abstinent and relapsed alcohol-dependent individuals. The questions of undesirable attitude were significantly related to the CSs of Employment, Drug use, Family/Social, and Psychiatric sections. Significant differences were observed in patient demographics, CS, and ASI Severity Rating (SR and interviewer’s subjective scoring between alcohol-dependent individuals and drug abusers. CSs in Japanese alcohol-dependent individuals were generally similar to corresponding CSs in individuals from other countries, with the exception of The Netherlands. Conclusions: This study demonstrated that the ASI-J is useful for understanding individual profiles of problems for each patient and planning customized treatment. The ASI-J served as a predictive tool for relapse and compliance to treatment afterward and was shown to be useful as a comparison tool in clarifying similarities and differences between substance abuser groups.

    Alcohol use during adolescence leads to increased risk of developing an alcohol use disorder (AUD) during adulthood. Converging evidence suggests that this period of enhanced vulnerability for developing an AUD may be due to the adolescent’s unique sensitivity and response to alcohol. Adolescent rats have been shown to be less sensitive to alcohol intoxication and withdrawal susceptibility; however age differences in ethanol pharmacokinetics may underlie these effects. Therefore, this study i...

    Treatment approaches which are used in the context of inpatient alcoholism treatment are frequently neither theoretically justified nor empirically examined. In view of the enormous method variety the necessity exists for the development of treatment guidelines in order to offer indicators of promising treatment achievement for practitioners and pension funds. In a first step, it must be examined which treatments are effective, which are ineffective and which are possibly even counter-productive. This article aims to give a comprehensive review of randomized-controlled studies/meta-analysis on the efficacy of different treatment approaches. This article reporting the literature review is part of a larger programme to develop clinical practice guidelines for rehabilitation which is supported in form, content and finance by the German Pension Institute for Salaried Employees (Bundesversicherungsanstalt für Angestellte, BfA). Summing up, treatment is effective compared to no treatment. Cognitive behavioural therapy included in a multimodal treatment program is effective. There are a number of treatment protocols for which controlled research has consistently found positive results like social skills training, community reinforcement approaches, behaviour contracting, motivation-enhancing treatment, and family/marital therapy. There is also a number of commonly used treatment approaches that brought neither a positive result or were counter productive like relapse prevention, non-behavioural marital therapy, and insight psychotherapy, confrontational counseling, education, relaxation training, and milieu therapy. Support for matching to a specific treatment is weak, but interventions against alcohol problems should be differentiated according to the severity of the alcohol problem. Since treatment evaluation is mainly accomplished in the US and supplying structures with respect to the US and Germany are substantially different, a generalized transmission of US

  10. Alcohol Dependence and Altered Engagement of Neural Networks in Risky Decisions

    Full Text Available Alcohol dependence is associated with heightened risk tolerance and altered decision- making. This raises the question as to whether alcohol dependent patients (ADP are incapable of proper risk assessment. We investigated how healthy controls (HC and ADP engage neural networks to cope with the increased cognitive demands of risky decisions. We collected fMRI data while 34 HC and 16 ADP played a game that included safe and risky trials. In safe trials, participants accrued money at no risk of a penalty. In risky trials, reward and risk simultaneously increased as participants were instructed to decide when to stop a reward accrual period. If the participant failed to stop before an undisclosed time, the trial would bust and participants would not earn the money from that trial. Independent Component Analysis was used to identify networks engaged during the anticipation and the decision execution of risky compared with safe trials. Like HC, ADP demonstrated distinct network engagement for safe and risky trials at anticipation. However, at decision execution, ADP exhibited severely reduced discrimination in network engagement between safe and risky trials. Although ADP behaviorally responded to risk they failed to appropriately modify network engagement as the decision continued, leading ADP to assume similar network engagement regardless of risk prospects. This may reflect disorganized network switching and a facile response strategy uniformly adopted by ADP across risk conditions. We propose that aberrant salience network (SN engagement in ADP might contribute to ineffective network switching and that the role of the SN in risky decisions warrants further investigation.

    There is expedient evidence showing that differences in adolescent alcohol consumption and other risk-behaviour depend on both family structure and family member drunkenness exposure. Data were obtained among adolescents (N = 12,115, mean age 14.9 ± 0.89) in Austria, Estonia, France, Germany, Hungary, Ireland, Israel, Italy, Romania, Slovenia and Spain within the European Union’s 7th Framework Programme funded project, ‘Saving and Empowering Young Lives in Europe (SEYLE)’. The current study reveals how adolescents’ alcohol consumption patterns are related to their family structure and having seen their family member drunk. The results revealed statistically significant differences in adolescent alcohol consumption depending on whether the adolescent lives in a family with both birth parents, in a single-parent family or in a family with one birth parent and one step-parent. The study also revealed that the abstaining from alcohol percentage among adolescents was greater in families with both birth parents compared to other family types. The study also showed that the more often adolescents see their family member drunk the more they drink themselves. There is no difference in adolescent drinking patterns whether they see their family member drunk once a month or once a week. This study gives an insight on which subgroups of adolescents are at heightened risk of alcohol abuse and that decrease of family member drunkenness may have positive effects on the drinking habits of their children.

    Anxiety disorders commonly co-occur with alcohol use disorders and reliably mark a poor response to substance abuse treatment. However, treating a co-occurring anxiety disorder does not reliably improve substance abuse treatment outcomes. Failure to account for individual differences in the functional dynamic between anxiety symptoms and drinking behavior might impede the progress and clarity of this research program. For example, while both theory and research point to the moderating role of...

    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.

    Aging is accompanied by changes in the redox balance that is additionally modified by alcohol. Ethanol metabolism is connected with generation of free radicals which can damage cell components especially when antioxidant mechanisms are not able to neutralize them. In connection with the necessity of prevention against oxidative consequences, natural antioxidants are looked for. A natural and commonly used component of the diets with antioxidant properties are teas, especially the black tea. This study provides evidence of the role of black tea in the protection of rat plasma proteins and lipids against oxidative stress caused by aging and ethanol intoxication. For 5 weeks, the rats (2-, 12-, and 24-months old) used for the experiment received a black tea beverage (3 g/l) without or with alcohol (given for 4 weeks). The decrease in antioxidant abilities determined as total antioxidant status during aging and ethanol intoxication resulted in enhanced lipid and protein oxidation (determined as malondialdehyde, carbonyl groups, dityrosine, tryptophan and sulfhydryl groups level). In consequence the decrease in anti-proteases (alpha-1-antitrypsin, alpha-2-macroglobulin) activity and the increase in proteases (elastase and cathepsin G) activity were observed. Black tea protected the plasma antioxidants and prevented oxidative modifications of lipid and protein observed during aging as well as ethanol intoxication. The results indicate that a shift into plasma proteolytic activity results from a decrease in antioxidant abilities, so the use of black tea appears to be beneficial in reducing oxidative stress caused by ethanol and/or aging.

    Recent large-scale disasters have made middle-ranked fire defense officers responsible for routine fire fighting activities, and a tendency of alcohol dependence associated with other stressful problems is noted in Japan. We assessed the alcohol dependence tendency with the alcohol use disorders identification test (AUDIT) in firefighters. Occupational stress, depression and other factors were evaluated with the brief job stress questionnaire, Center for Epidemiologic Studies depression scale, K10 and a face sheet. Subjects were 294 male personnel in a local fire defense headquarters, and 246 of them (83.4%) answered effectively. Data were analyzed first with univariate analysis between the AUDIT score and other items, and then with multivariate analysis of the AUDIT score as a dependent variable and other items as independent variables. The AUDIT score (mean ± SD) in the 246 respondents classified by age ranges was 7.9 ± 5.4 points (the lowest, 0 points; the highest, 27 points). The multivariate analysis showed significant correlations of the AUDIT score with the workplace environment (P = 0.003) and the rank of work (P = 0.019). The present survey was cross-sectional, and we could not clarify the subjects’ past drinking states and applicability of the results to the whole Japan personnel. It is necessary to further investigate the relationship between alcoholism and depression in the present subjects. As a pilot study, we first clarified the state of alcohol dependence in personnel in a Japanese local fire fighting organization, and examined related factors. PMID:24031141

    Aim Familial loading for alcohol dependence (AD) and variation in genes reported to be associated with AD or BMI were tested in a longitudinal study. Materials & methods Growth curve analyses of BMI data collected at approximately yearly intervals and obesity status (BMI > 30) were examined. Results High-risk males were found to have higher BMI than low-risk males, beginning at age 15 years (2.0 kg / m2 difference; p = 0.046), persisting through age 19 years (3.3 kg/m2 difference; p = 0.005). CHRM2 genotypic variance predicted longitudinal BMI and obesity status. Interactions with risk status and sex were also observed for DRD2 and FTO gene variation. Conclusion Variation at loci implicated in addiction may be influential in determining susceptibility to increased BMI in childhood and adolescence. PMID:25155933

    Theoretical and experimental studies on (3)J(C2H6eq) NMR spin-spin coupling constants in both the 2-X-4-t-butyl-cyclohexanone (X = H, CH(3), F, Cl, and Br) and in their alcohol derivatives series are reported. Results thus found are rationalized in terms of the transmission of the Fermi contact contribution to such couplings. To this end, dependencies of (3)J(C2H6eq) couplings versus the C(2)-C(1)-C(6) angle are compared in both series for equatorial and axial X orientations. The main trend is described in terms of the rear lobes interaction. Besides, for X = halogen atom in equatorial orientation a rather strong interaction between oxygen and halogen lone pairs is observed, and its influence on (3)J(C2H6eq) couplings is discussed and rationalized in terms of different Fermi contact transmission pathways.

    Corticotropin-releasing hormone (CRH) and its receptor, CRH receptor-1 (CRHR1), have a key role in alcoholism. Especially, post-dependent and stress-induced alcohol intake involve CRH/CRHR1 signaling within extra-hypothalamic structures, but a contribution of the hypothalamic-pituitary-adrenal (HPA......, a conditional brain-specific Crhr1-knockout (Crhr1(NestinCre)) and a global knockout mouse line were studied for basal alcohol drinking, stress-induced alcohol consumption, deprivation-induced intake, and escalated alcohol consumption in the post-dependent state. In a second set of experiments, we tested CRHR1...... antagonists in the ADE model. Stress-induced augmentation of alcohol intake was lower in Crhr1(NestinCre) mice as compared with control animals. Crhr1(NestinCre) mice were also resistant to escalation of alcohol intake in the post-dependent state. Contrarily, global Crhr1 knockouts showed enhanced stress...

  4. Dissociable patterns in the control of emotional interference in adults with attention-deficit/hyperactivity disorder (ADHD and in adults with alcohol dependence.

    Full Text Available OBJECTIVES: To effectively manage current task demands, attention must be focused on task-relevant information while task-irrelevant information is rejected. However, in everyday life, people must cope with emotions, which may interfere with actual task demands and may challenge functional attention allocation. Control of interfering emotions has been associated with the proper functioning of the dorsolateral prefrontal cortex (DLPFC. As DLPFC dysfunction is evident in subjects with ADHD and in subjects with alcohol dependence, the current study sought to examine the bottom-up effect of emotional distraction on task performance in both disorders. METHODS: Male adults with ADHD (n = 22, male adults with alcohol dependence (n = 16, and healthy controls (n = 30 performed an emotional working memory task (n-back task. In the background of the task, we presented neutral and negative stimuli that varied in emotional saliency. RESULTS: In both clinical groups, a working memory deficit was evident. Moreover, both clinical groups displayed deficient emotional interference control. The n-back performance of the controls was not affected by the emotional distractors, whereas that of subjects with ADHD deteriorated in the presence of low salient distractors, and that of alcoholics did not deteriorate until high salient distractors were presented. Subsequent to task performance, subjects with ADHD accurately recognized more distractors than did alcoholics and controls. In alcoholics, picture recognition accuracy was negatively associated with n-back performance, suggesting a functional association between the ability to suppress emotional distractors and successful task performance. In subjects with ADHD, performance accuracy was negatively associated with ADHD inattentive symptoms, suggesting that inattention contributes to the performance deficit. CONCLUSIONS: Subjects with ADHD and alcoholics both display an emotional interference control

    Background In Japan, the three chief traditional guidelines for sobriety (3CGS) are regular medical checkups, participation in self-help groups, and pharmacotherapy with antidipsotropics. However, the official record of the origins of 3CGS is not clear. The aim of this current study was to assess 3CGS by an examination of the prognosis of patients with alcohol dependence 2 years after their discharge from a residential treatment program. Subjects and methods The association between subjects’ abstinence from alcohol and their regular medical checkups, participation in self-help groups, and treatment with antidipsotropics were prospectively examined. Two years after discharge, the relationship between the 3CGS compliance and abstinence rates was investigated as the primary outcome. In addition, the following were examined as secondary outcomes: the time taken till the first drink after discharge, whether the participants were readmitted to residential treatment, the number of days to readmission, the number of heavy drinking days, and recovery. Results A total of 98 patients participated. The perfect and partial abstinence rates for patients who followed all the principles of 3CGS were significantly higher than those for patients who followed no guidelines (P<0.05 and P<0.01, respectively). The perfect abstinence rates for patients who had continued attending checkup sessions (P<0.001) and who were taking antidipsotropics (P<0.05) were significantly higher than those for patients who did not follow these components of 3CGS. However, the perfect abstinence rates were not higher for patients who had continued to participate in self-help groups. In addition, the perfect abstinence rate was statistically associated with regular medical checkups (adjusted odds ratio =5.33, 95% confidence interval =1.35–21.0) and participation in self-help groups (adjusted odds ratio =3.79, 95% confidence interval =1.17–12.3). Conclusion This study, reports the effectiveness of 3CGS

    The aim of the present study was to evaluate the effect of 15% alcohol dependence on ligature-induced alveolar bone loss and TNF-α secretion in Wistar rats. Thirty-three male Wistar rats aged 45-60 days (mean weight=253 g) were randomly allocated test or control groups. Test group (n=18) received 15% alcohol as liquid intake and control group (n=15) received water during the experimental period. TNF-α was analyzed by ELISA assay in 11 animals per group. After 14 days of alcohol/water intake, alcohol dependency was assessed and silk ligatures were placed around the left second upper molars. Ligature presence and body weight were checked weekly. After 40 days, animals were sacrificed and the maxillae were defleshed for morphometric analysis using standardized images. All animals in the test group displayed signs of alcohol dependency at day 14. No statistically significant differences in final body weight (334.83±21.38 vs. 322.48±30.65 g, p=0.20) were observed between groups. In relation to alveolar bone loss, no statistically significant difference was observed among test and control groups both for ligated teeth (0.76±0.06 vs. 0.74±0.10 mm, p=0.60) and unligated teeth (0.41±0.16 vs. 0.35±0.05 mm, p=0.22). The TNF-α secretion also did not display statistically significant differences between test and control groups (10.78±1.84 vs. 12.13±2.11 pg/mL, p=0.12). It may be concluded that 15% alcohol dependency was not capable to alter alveolar bone loss and TNF-α secretion in Wistar rats.

    Full Text Available ABSTRACT Objective The objective of this study was to replicate Babor's Typology and to explore clinical features related to personality traits that may underlie this classification, in order to improve its therapeutic possibilities. Methods Observational prospective study on a group of 273 male alcoholics. After a replication of Babor's variables, Cluster Analysis, Chi-Square – applied on clinical variables related to a Lappda Tipology – and Kappa tests were performed. Results The study identified two distinct clusters that held similar features to those described for the Type A/Type B classification. Besides presenting a lower socio-economic situation, Cluster 2 patients were associated with higher vulnerability and severe clinical features and also differed from Cluster 1 in their response to treatment. These replicated clusters retained connections and also differences in relation to the variables derived from the Lappda Typology. Conclusion Considering that each of the two replicated clusters seem to be associated to different personality traits – according to their correlations to the affective, cognitive and behavioral dimensions brought forward by the Lappda Typology – it is acceptable that this study may contribute to the development of more comprehensive and effective therapeutic strategies specifically tailored to target more specific personality traits of these subgroups of alcoholic patients.

    In 46 alcoholic patients the association of wedged-to-free hepatic-vein pressure with other variables (clinical, histologic, hemodynamic, and liver function data) was studied by means of multiple regression analysis, taking the wedged-to-free hepatic-vein pressure as the dependent variable. Four...... variables showed significant independent association with the wedged-to-free hepatic-vein pressure: indocyanine green clearance (p = 0.031), degree of necrosis (p = 0.023), degree of hepatic architectural destruction (graded as: preserved architecture, nodules alternating with preserved architecture......, totally destroyed architecture) (p = 2.3 X 10(-6) and sex (p = 0.0024), male sex being associated with higher wedged-to-free hepatic-vein pressure. The multiple coefficient of determination (R2) was 0.63; thus, 63% of the variation in the wedged-to-free hepatic-vein pressure was 'explained' by variation...

    Full Text Available The brain histaminergic system is one of the diffuse modulatory neurotransmitter systems which regulate neuronal activity in many brain areas. Studies on both rats and mice indicate that histamine H3 receptor antagonists decrease alcohol drinking in several models, like operant alcohol administration and drinking in the dark paradigm. Alcohol-induced place preference is also affected by these drugs. Moreover, mice lacking H3R do not drink alcohol like their wild type littermates, and they do not show alcohol-induced place preference. Although the mechanisms of these behaviors are still being investigated, we propose that H3R antagonists are promising candidates for use in human alcoholics, as these drugs are already tested for treatment of other disorders like narcolepsy and sleep disorders.

    Impairment of executive functions (EFs) mediated by the prefrontal lobe is regarded as a cognitive endophenotype of alcohol dependence, being observed both in probands and in healthy offspring. Given its impact on the anatomy of the prefrontal cortex, the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism may well be involved in this specific endophenotype. Forty-six healthy adult children of alcoholics (HACA) and 82 healthy controls (HC) took part in the study. All the participants were assessed with the Diagnostic Interview for Genetic Studies, and their family histories of alcohol and substance use were assessed with the Family Informant Schedule and Criteria. The Trail Making Test, Arithmetic Switching Task, Stroop Color-Word Test and Wisconsin Card Sorting Test were administered to assess EFs. An overall executive factor score was calculated using factorial analyses. Genotyping of the BDNF Val66Met polymorphism was performed using the TaqMan® allelic discrimination assay. HACA had significantly lower EFs performance than HC. Genetic analysis showed that BDNF genotype distributions were in Hardy-Weinberg equilibrium in the HACA and HC. Genotype and allele distributions did not differ significantly between the two groups. Participants with the Met allele performed significantly more poorly than participants with the Val allele, and a group by allele interaction was observed, the BDNF Met allele being associated with a poorer executive factor score in the HACA group. These results suggest that the BDNF Val66Met polymorphism may contribute to alcohol dependence vulnerability via lower EFs performance.

    Carbohydrate-deficient transferrin (CDT) was analyzed by a modified radioimmunoassay test in a random population sample of 400 individuals, and results were compared with reported alcohol intake derived from a structured questionnaire. Among the 180 men, the test was found to be acceptable...... with respect to detecting harmful alcohol intake (> 35 beverages/week) and alcohol intake above the recommended level (21 beverages/week), although the positive predictive values were low. Among the 220 women, the test was invalid with low predictive values. CDT was compared with other known markers of high...... alcohol intake, and it was observed that CDT had higher sensitivity and specificity than AST and short Michigan Alcoholism Screening Test (sMAST) in men, whereas the positive and negative predictive values were low in all tests. A combination of CDT and AST proved to be a better marker of both harmful...

    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 ma...

    2014-02-01

    In-situ monitoring of silver nanoparticle formation was studied in thin films of polyvinyl alcohol and silver nitrate. We proposed the observation of surface-enhanced Raman spectroscopy (SERS) as a novel and simple technique to record the growth of silver nanoparticles in polyvinyl alcohol thin films. Observed enhancement in the Raman bands of polyvinyl alcohol is explained through the localized surface plasmon resonance of silver nanoparticles. Influence of temperature generated by silver nanoparticles on the formation of nanoparticles is also discussed.

    Full Text Available Abstract Background Alcohol misuse has been linked to intimate partner violence (IPV. However, this association is not usually examined in Russia. Moreover, more investigation is required as to whether specific drinking contexts are also associated with IPV. The objectives of this study are: to investigate whether alcohol misuse is associated with IPV and to further examine whether specific drinking contexts among drinkers are associated with IPV. Methods A questionnaire was used to collect information on demographics, health status, alcohol use, and violence involving sexual partners among 440 participants who were recruited from an STI (sexually transmitted infection clinic center in St. Petersburg, Russia for a cross-sectional study from 2008 to 2009. Multivariate logistic regression was used for analysis. Results Overall, 47.0% participants were classified as misusing alcohol and 7.2% participants perpetrated IPV in the past three months. Participants with alcohol misuse were 3.28 times (OR: 3.28; 95% CI: 1.34-8.04 as likely as those without alcohol misuse to perpetrate IPV. Among participants who had consumed alcohol in the past three months, those who usually drank on the streets or in parks (OR: 5.62; 95% CI: 1.67-18.90 were more likely to perpetrate IPV. Conclusions Both alcohol misuse and certain drinking contexts (e.g., drinking on the streets or at parks were associated with IPV. The association between drinking contexts and IPV needs further investigation, as do the underlying mechanisms for this association. IPV prevention initiatives might benefit from reducing alcohol misuse. Drinking contexts such as drinking on the streets or at parks as well as the factors related to the use of alcohol in these contexts may also need to be addressed.

    Thermoplastic polyurethane (TPU) is a rubber like material with outstanding properties, e.g. for seal applications. TPU basically provides high strength, low frictional behavior and excellent wear resistance. Though, due to segmented structure of TPU, which is composed of hard segments (HSs) and soft segments (SSs), physical properties depend strongly on the morphological arrangement of the phase separated HSs at a certain ratio of HSs to SSs. It is obvious that the TPU deforms differently depending on its bulk morphology. Basically, the morphology can either consist of HSs segregated into small domains, which are well dispersed in the SS matrix or of few strongly phase separated large size HS domains embedded in the SS matrix. The morphology development is hardly ruled by the melt processing conditions of the TPU. Depending on the morphology, TPU provides quite different physical properties with respect to strength, deformation behavior, thermal stability, creep resistance and tribological performance. The paper deals with the influence of important melt processing parameters, such as temperature, pressure and shear conditions, on the resulting physical properties tested by tensile and relaxation experiments. Furthermore the morphology is studied employing differential scanning calorimeter (DSC), transmission light microscopy (TLM), scanning electron beam microscopy (SEM) and transmission electron beam microscopy (TEM) investigations. Correlations between processing conditions and resulting TPU material properties are elaborated. Flow and shear simulations contribute to the understanding of thermal and flow induced morphology development.

    Alcohol use and abuse profoundly influences a variety of behaviors, including social interactions. In some cases, it erodes social relationships; in others, it facilitates sociality. Here, we show that voluntary alcohol consumption can inhibit male partner preference (PP) formation (a laboratory proxy for pair bonding) in socially monogamous prairie voles (Microtus ochrogaster). Conversely, female PP is not inhibited, and may be facilitated by alcohol. Behavior and neurochemical analysis suggests that the effects of alcohol on social bonding are mediated by neural mechanisms regulating pair bond formation and not alcohol's effects on mating, locomotor, or aggressive behaviors. Several neuropeptide systems involved in the regulation of social behavior (especially neuropeptide Y and corticotropin-releasing factor) are modulated by alcohol drinking during cohabitation. These findings provide the first evidence to our knowledge that alcohol has a direct impact on the neural systems involved in social bonding in a sex-specific manner, providing an opportunity to explore the mechanisms by which alcohol affects social relationships.

    Event-related brain oscillations (EROs) represent highly heritable neuroelectrical correlates of human perception and cognitive performance that exhibit marked deficits in patients with various psychiatric disorders. We report the results of the first genome-wide association study (GWAS) of an ERO endophenotype-frontal theta ERO evoked by visual oddball targets during P300 response in 1,064 unrelated individuals drawn from a study of alcohol dependence. Forty-two SNPs of the Illumina HumanHap 1 M microarray were selected from the theta ERO GWAS for replication in family-based samples (N = 1,095), with four markers revealing nominally significant association. The most significant marker from the two-stage study is rs4907240 located within ARID protein 5A gene (ARID5A) on chromosome 2q11 (unadjusted, Fisher's combined P = 3.68 × 10⁻⁶). However, the most intriguing association to emerge is with rs7916403 in serotonin receptor gene HTR7 on chromosome 10q23 (combined P = 1.53 × 10⁻⁴), implicating the serotonergic system in the neurophysiological underpinnings of theta EROs. Moreover, promising SNPs were tested for association with diagnoses of alcohol dependence (DSM-IV), revealing a significant relationship with the HTR7 polymorphism among GWAS case-controls (P = 0.008). Significant recessive genetic effects were also detected for alcohol dependence in both case-control and family-based samples (P = 0.031 and 0.042, respectively), with the HTR7 risk allele corresponding to theta ERO reductions among homozygotes. These results suggest a role of the serotonergic system in the biological basis of alcohol dependence and underscore the utility of analyzing brain oscillations as a powerful approach to understanding complex genetic psychiatric disorders.

    Full Text Available The purpose of this study was to conduct a literature review of cost-benefit studies on pharmacotherapy and psychotherapy treatments of alcohol dependence (AD. A literature search was performed in multiple electronic bibliographic databases. The search identified seven psychotherapy studies from the USA and two pharmacotherapy studies from Europe. In the psychotherapy studies, major benefits are typically seen within the first six months of treatment. The benefit-cost ratio ranged from 1.89 to 39.0. Treatment with acamprosate was found to accrue a net benefit of 21,301 BEF (528 € per patient over a 24-month period in Belgium and lifetime benefit for each patient in Spain was estimated to be Pta. 3,914,680 (23,528 €. To date, only a few studies exist that have examined the cost-benefit of psychotherapy or pharmacotherapy treatment of AD. Most of the available treatment options for AD appear to produce marked economic benefits.

    Pathological gambling (PG) shares clinical characteristics such as craving and loss of control with substance use disorders and is thus considered a behavioral addiction. While functional alterations in the mesolimbic reward system have been correlated with craving and relapse in substance use disorders, only a few studies have examined this brain circuit in PG, and no direct comparison has been conducted so far. Thus, we investigated the neuronal correlates of reward processing in PG in contrast to alcohol-dependent (AD) patients and healthy subjects. Eighteen PG patients, 15 AD patients and 17 controls were investigated with a monetary incentive delay task, in which visual cues predict the consequence (monetary gain, avoidance of loss, none) of a fast response to a subsequent target stimulus. Functional magnetic resonance imaging data were analyzed to account for possible confounding factors such as local gray matter volume. Activity in the right ventral striatum during loss anticipation was increased in PG patients compared with controls and AD patients. Moreover, PG patients showed decreased activation in the right ventral striatum and right medial prefrontal cortex during successful loss avoidance compared with controls, which was inversely associated with severity of gambling behavior. Thus, despite neurobiological similarities to substance use disorders in reward processing, as reported by previous studies, we found relevant differences with respect to the anticipation of loss as well as its avoidance (negative reinforcement), which further contributes to the understanding of PG.

    There is preliminary evidence that approach avoid training can shift implicit alcohol associations and improve treatment outcomes. We sought to replicate and extend those findings in US undergraduate social drinkers (Study 1) and at-risk drinkers (Study 2). Three adaptations of the approach avoid task (AAT) were tested. The first adaptation - the approach avoid training - was a replication and targeted implicit alcohol approach associations. The remaining two adaptations - the general identity and personalized identity trainings - targeted implicit drinking identity associations, which are robust predictors of hazardous drinking in US undergraduates. Study 1 included 300 undergraduate social drinkers. They were randomly assigned to real or sham training conditions for one of the three training adaptations, and completed two training sessions, spaced one week apart. Study 2 included 288 undergraduates at risk for alcohol use disorders. The same training procedures were used, but the two training sessions occurred within a single week. Results were not as expected. Across both studies, the approach avoid training yielded no evidence of training effects on implicit alcohol associations or alcohol outcomes. The general identity training also yielded no evidence of training effects on implicit alcohol associations or alcohol outcomes with one exception; individuals who completed real training demonstrated no changes in drinking refusal self-efficacy whereas individuals who completed sham training had reductions in self-efficacy. Finally, across both studies, the personalized identity training yielded no evidence of training effects on implicit alcohol associations or alcohol outcomes. Despite having relatively large samples and using a well-validated training task, study results indicated all three training adaptations were ineffective at this dose in US undergraduates. These findings are important because training studies are costly and labor-intensive. Future research

    primary health care services for other reasons. The aim of the present study is to describe the differential characteristics of AD patients in primary care, distinguishing between those who receive treatment and those who do not, and their reasons for not seeking it. In a cross-sectional study patients were evaluated by their general practitioner (GP) and interviewed by a member of the research team. Sociodemographic, diagnostic and clinical data were collected. From 1,372 patients interviewed in Catalonia, 118 (8.6%) were diagnosed as AD. These patients showed a lower socioeconomic status (48.3% vs 33.3%, odds ratio 2.02), higher unemployment rates (32.2% vs 19.2 %, odds ratio 2.11), and greater psychological distress and disability. Patients with AD receiving treatment (16.9%), were older (44 vs 36 years of age), reported higher unemployment rates (66% vs 25.5%, odds ratio 6.32) and higher daily alcohol consumption (61.5 vs 23.7 grams), suggesting a more advanced disease. Patients with AD in general showed a higher degree of comorbidity compared to other patients, with patients in treatment showing the most elevated level. The main reasons given for not seeking treatment were shame, fear of giving up drinking and barriers to treatment. Taken together, the data suggest the need to implement earlier strategies for the detection and treatment of AD. PMID:26990264

    The hormone glucagon-like peptide-1 (GLP-1) regulates appetite and food intake. GLP-1 receptor (GLP-1R) activation also attenuates the reinforcing properties of alcohol in rodents. The present translational study is based on four human genetic association studies and one preclinical study providing data that support the hypothesis that GLP-1R may have a role in the pathophysiology of alcohol use disorder (AUD). Case-control analysis (N = 908) was performed on a sample of individuals enrolled in the National Institute on Alcohol Abuse and Alcoholism (NIAAA) intramural research program. The Study of Addiction: Genetics and Environment (SAGE) sample (N = 3803) was used for confirmation purposes. Post hoc analyses were carried out on data from a human laboratory study of intravenous alcohol self-administration (IV-ASA; N = 81) in social drinkers and from a functional magnetic resonance imaging study in alcohol-dependent individuals (N = 22) subjected to a Monetary Incentive Delay task. In the preclinical study, a GLP-1R agonist was evaluated in a mouse model of alcohol dependence to demonstrate the role of GLP-1R for alcohol consumption. The previously reported functional allele 168Ser (rs6923761) was nominally associated with AUD (P = 0.004) in the NIAAA sample, which was partially replicated in males of the SAGE sample (P = 0.033). The 168 Ser/Ser genotype was further associated with increased alcohol administration and breath alcohol measures in the IV-ASA experiment and with higher BOLD response in the right globus pallidus when receiving notification of outcome for high monetary reward. Finally, GLP-1R agonism significantly reduced alcohol consumption in a mouse model of alcohol dependence. These convergent findings suggest that the GLP-1R may be an attractive target for personalized pharmacotherapy treatment of AUD.

  1. Gamma Hydroxybutyric Acid (GHB for the Treatment of Alcohol Dependence: A Review

    Directory of Open Access Journals (Sweden)

    Mauro Bernardi

    2009-06-01

    Full Text Available Gamma-hydroxybutyric acid (GHB is a short-chain fatty acid structurally similar to the inhibitory neurotransmitter γ-aminobutyric acid. Clinical trials have demonstrated that 50-100 mg/kg of GHB fractioned into three or six daily doses is able to suppress alcohol withdrawal symptoms and facilitates the maintenance of abstinence from alcohol. These studies have also shown that GHB craving episodes are a very limited phenomenon (about 10-15%. Thus, physicians with access should consider the clinical efficacy of GHB as a valid pharmacological tool for the treatment of alcohol addiction.

    Full Text Available The main point of the paper is to investigate how much the modeled ring current depends on the representations of magnetic and electric fields and boundary conditions used in simulations. Two storm events, one moderate (SymH minimum of −120 nT on 6–7 November 1997 and one intense (SymH minimum of −230 nT on 21–22 October 1999, are modeled. A rather simple ring current model is employed, namely, the Inner Magnetosphere Particle Transport and Acceleration model (IMPTAM, in order to make the results most evident. Four different magnetic field and two electric field representations and four boundary conditions are used. We find that different combinations of the magnetic and electric field configurations and boundary conditions result in very different modeled ring current, and, therefore, the physical conclusions based on simulation results can differ significantly. A time-dependent boundary outside of 6.6 RE gives a possibility to take into account the particles in the transition region (between dipole and stretched field lines forming partial ring current and near-Earth tail current in that region. Calculating the model SymH* by Biot-Savart's law instead of the widely used Dessler-Parker-Sckopke (DPS relation gives larger and more realistic values, since the currents are calculated in the regions with nondipolar magnetic field. Therefore, the boundary location and the method of SymH* calculation are of key importance for ring current data-model comparisons to be correctly interpreted.

    Full Text Available We assessed a set of biological (HDL, LDL, SGOT,SGPT, GGT, HTc, Hb and T levels and psychometric variables (investigated through HAM-D, HAM-A, GAS, Liebowitz Social Anxiety Scale, Mark & Mathews Scale, Leyton scale, and Pilowski scale in a sample of 64 alcohol dependent patients, at baseline and after a detoxification treatment. Moreover, we recruited 47 non-consanguineous relatives who did not suffer alcohol related disorders and underwent the same tests. In both groups we genotyped 11 genetic variations (rs1800587; rs3087258; rs1799724; 5-HTTLPR; rs1386493; rs1386494; rs1487275; rs1843809; rs4570625; rs2129575; rs6313 located in genes whose impact on alcohol related behaviors and disorders has been hypothesized (IL1A, IL1B, TNF, 5-HTTLPR, TPH2 and HTR2A. We analyzed the epistasis of these genetic variations upon the biological and psychological dimensions in the cases and their relatives. Further on, we analyzed the effects of the combined genetic variations on the short – term detoxification treatment efficacy. Finally, being the only not yet investigated variation within this sample, we analyzed the impact of the rs6313 alone on baseline assessment and treatment efficacy. We detected the following results: the couple rs6313 + rs2129575 affected the Leyton -Trait at admission (p = 0.01 (obsessive-compulsive trait, whilst rs1800587 + 5-HTTLPR impacted the Pilowski test at admission (p = 0.01 (hypochondriac symptoms. These results did not survive Bonferroni correction (p ≤ 0.004. This lack of association may depend on the incomplete gene coverage or on the small sample size which limited the power of the study. On the other hand, it may reflect a substantial absence of relevance of the genotype variants toward the alcohol related investigated dimensions. Nonetheless, the marginal significance we detected could witness an informative correlation worth investigating in larger samples.

  12. Long-term misuse of zopiclone in an alcohol dependent woman with a history of anorexia nervosa: a case report

    2010-12-01

    Full Text Available Abstract Introduction The Z-drugs, zaleplon, zopiclone and zolpidem, are short-acting hypnotics which act at the same receptor as the benzodiazepines, but seemingly without the potential for misuse and the development of dependence of the older benzodiazepines. However, with increased prescribing of Z-drugs, reports of misuse and possible dependence began to appear in the literature, particularly in people with a history of substance misuse and comorbid psychiatric illness. Here we report the case of a woman with a history of chronic zopiclone use and anorexia nervosa, admitted for alcohol detoxification. Case presentation A 31-year old Caucasian British woman with a history of long-term zopiclone use and anorexia nervosa was admitted as an inpatient for a ten-day alcohol detoxification. Her weekly (four days out of seven intake of alcohol was 180 units and her daily intake of zopiclone, 30 mg. Apart from a short period five years ago, she had been taking zopiclone for 13 years at daily doses of up to 90 mg. She admitted to using 'on top' of her prescribed medication, purchasing extra tablets from friends or receiving them gratis from her partner. After detoxification from alcohol and zopiclone, she was prescribed diazepam which she found ineffectual and voiced her intention of returning to zopiclone on leaving the hospital. Conclusion Zopiclone is generally regarded as safer than benzodiazepines, however, this particular individual, who was using high doses of zopiclone over many years, may provide further evidence of a risk of dependency when this drug is prescribed for substance users with a comorbid psychiatric illness.

    Alcohol dependence is a severe disorder contributing substantially to the global burden of disease. Despite the detrimental consequences of chronic alcohol abuse and dependence, effective prevention strategies as well as treatment options are largely missing to date. Accumulating evidence suggests that gene-environment interactions, including epigenetic mechanisms, play a role in the etiology of alcohol dependence. A recent epigenome-wide study reported widespread alterations of DNA methylation patterns in alcohol dependent patients compared to control individuals. In the present study, we validate and replicate one of the top findings from this previous investigation in an independent cohort: the hypomethylation of GDAP1 in patients. To our knowledge, this is the first independent replication of an epigenome-wide finding in alcohol dependence. Furthermore, the AUDIT as well as the GSI score were negatively associated with GDAP1 methylation and we found a trend toward a negative association between GDAP1 methylation and the years of alcohol dependency, pointing toward a potential role of GDAP1 hypomethylation as biomarker for disease severity. In addition, we show that the hypomethylation of GDAP1 in patients reverses during a short-term alcohol treatment program, suggesting that GDAP1 DNA methylation could also serve as a potential biomarker for treatment outcome. Our data add to the growing body of knowledge on epigenetic effects in alcohol dependence and support GDAP1 as a novel candidate gene implicated in this disorder. As the role of GDAP1 in alcohol dependence is unknown, this novel candidate gene should be followed up in future studies.

    The present study examined the association between personality pathology (PP) and alcohol dependence (AD; both lifetime and in the past 12 months) among middle-aged to older adults incorporating three sources of assessment, specifically, diagnostic interviews as well as self- and informant reports. We collected data from a representative sample of community participants (N = 1,630; ages 54-65 years) and their informants (N = 1,462). Measures employed were the substance use disorder sections of the Mini-International Neuropsychiatric Interview Schedule for Mental Disorders, the Structured Interview for DSM-IV Personality (American Psychiatric Association, 2000, Diagnostic and Statistical Manual of Mental Disorders, 4th ed., text rev.; DSM-IV-TR SIDP) and the NEO-Personality Inventory-Revised (Costa, P. T., & McCrae, R. R., Revised NEO-Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI) manual, 1992, Odessa, FL, Psychological Assessment Resources; self-report and informant versions). To complement the diagnostic interview for personality disorders (PDs), we utilized a PD-count technique derived from the five-factor model (FFM), which provided an index of PP liability. Factors representing lifetime and past-12 month AD were regressed on each of the 10 PP factors constructed from the SIDP interview, as well as self-report and informant FFM-count scores. Lifetime diagnosis of AD was positively associated with higher scores on several PP measures, including paranoid, schizotypal, antisocial, borderline, histrionic, and narcissistic PP. There was an inverse relation between lifetime AD and the factor score for obsessive-compulsive PP. With regard to AD in the past 12 months, antisocial, borderline, histrionic, and narcissistic PP factors were significantly associated with increased risk for AD, whereas the obsessive-compulsive and schizoid PP factors were associated with decreased risk for AD.

    Full Text Available Este artigo procura examinar a questão da herdabilidade na dependência do álcool. Através da revisão de estudos em famílias, em gêmeos e de adoção, encontramos evidências para afirmar a importância dos fatores genéticos na transmissão da vulnerabilidade a esta dependência. Essa transmissão pode ser melhor compreendida através de um modelo epigenético de desenvolvimento do transtorno, no qual condições biológicas hereditárias associem-se a situações ambientais ao longo da vida para a produção da dependência. Neste artigo, apresentamos essas condições biológicas intermediárias vinculadas ao alto risco para dependência do álcool. Por fim, descrevemos os estudos moleculares que vêm estabelecendo associações entre polimorfismos e a dependência do álcool, com relevo para o sistema dopaminérgico.In this article we examined the heritability of alcohol dependence. A review of family, twin and adoption studies, allowed us to support the thesis of an important genetic component in this dependence. The transmission of this heritability occurs through a biological vulnerability associated to environmental factors, in a model called epigenetic. We also discussed the relationship between biological vulnerability and high-risk phenotypes for alcohol dependence. In the end, we briefly comment on the molecular genetic studies associated with this disorder.

    2013-07-01

    Our previous observation that NADP-dependent secondary alcohol dehydrogenase (ADH-1) is down-regulated in metronidazole-resistant Trichomonas vaginalis isolates prompted us to further characterise the enzyme. In addition to its canonical enzyme activity as a secondary alcohol dehydrogenase, a pronounced, so far unknown, background NADPH-oxidising activity in absence of any added substrate was observed when the recombinant enzyme or T. vaginalis extract were used. This activity was strongly enhanced at low oxygen concentrations. Unexpectedly, all functions of ADH-1 were efficiently inhibited by coenzyme A which is a cofactor of a number of key enzymes in T. vaginalis metabolism, i.e. pyruvate:ferredoxin oxidoreductase (PFOR). These observations could be extended to Entamoeba histolytica and Tritrichomonas foetus, both of which have a homologue of ADH-1, but not to Giardia lamblia which lacks an NADP-dependent secondary alcohol dehydrogenase. Although we could not identify the substrate of the observed background activity, we propose that ADH-1 functions as a major sink for NADPH in microaerophilic parasites at low oxygen tension.

    The neurotrophin brain-derived neurotrophic factor (BDNF) has been suggested to be involved in the development and maintenance of addictive and other psychiatric disorders. Also, interactions of γ-aminobutyric acid (GABA)-ergic compounds and BDNF have been reported. The objective of this study was to investigate serum levels of BDNF over time in alcohol-dependent patients receiving individually titrated high-dose treatment (30-270mg/d) with the GABA-B receptor agonist baclofen or placebo for up to 20 weeks. Serum levels of BDNF were measured in patients of the baclofen/placebo group at baseline (t0), 2 weeks after reaching individual high-dose of baclofen/placebo treatment (t1) and after termination of study medication (t2) in comparison to carefully matched healthy controls. No significant differences in serum levels of BDNF between the baclofen and the placebo group or healthy controls were found at t0, t1, or at t2. Based on these findings, it seems unlikely that baclofen exerts a direct effect on serum levels of BDNF in alcohol-dependent patients. Future studies are needed to further explore the mechanism of action of baclofen and its possible relationship to BDNF in alcohol use disorders. PMID:27107672

    The specific features of alcohol behavior were studied in MR and MNRA rats that exhibit an opposite reaction to emotional stress. We evaluated the effect of a dipeptide anxiolytic GB-115 (N-phenyl-hexanoyl-glycyl-L-tryptophan amide, neuropeptide cholecystokinin-4 analogue with antagonistic activity) on alcohol motivation in rats, which was formed over 12 months. High-emotionality MR rats were more sensitive to the anxiolytic effect of ethanol in the conflict situation test than low-emotionality MNRA rats. MNRA rats consumed a greater amount of ethanol under a free-choice condition with 15% ethanol solution and water (as in comparison with MR rats). However, the behavior of MR rats was transformed due to a significant increase in alcohol motivation from the 5th month of long-term free access to ethanol. An anxiolytic GB-115 (0.025 mg/kg intraperitoneally for 14 days) with selective activity in high-emotionality rats was shown to reduce significantly the average daily consumption and alcohol-deprivation effect in MR rats, but did not modulate ethanol addiction in MNRA rats.

    Objective To determine if salivary biomarkers demonstrate utility for identifying aspects of myocardial necrosis. Methods Twenty-one patients undergoing alcohol septal ablation (ASA) for treatment of hypertrophic cardiomyopathy provided serum and unstimulated whole saliva at baseline and incremental time points post-ASA. Samples were analyzed for seven biomarkers related to myocardial damage, inflammation and tissue remodeling using immunosorbent assays. Levels were compared to baseline and levels observed in 97 healthy controls. Results Biomarkers of myocardial damage and inflammation (i.e., troponin I, creatine kinase-MB, myoglobin, C-reactive protein) rose in serum 2 to 812-fold after ASA (p<0.01). Significant elevations of 2 to 3.5-fold were observed with C-reactive protein and troponin I in saliva (p<0.02). Significant correlations between levels in serum and saliva were observed for C-reactive protein, matrix metalloproteinase-9, and myeloperoxidase (p < 0.001). Conclusions Select salivary biomarkers reflect changes that occur during, and subsequent to, myocardial necrosis caused by ASA. PMID:23021916

    Alcohol use disorders (AUD) cause significant morbidity and mortality worldwide, but pharmacological treatments for them are underused, despite evidence of efficacy. Acamprosate, naltrexone, nalmefene and disulfiram are all approved in one or more region for the treatment of AUD. Baclofen currently has a temporary indication in France. Safety considerations for using psychopharmacological treatments in this patient group include the impact of concurrent alcohol consumption at high levels; multiple physical comorbidities that may interfere with pharmacological effects, distribution and metabolism; and concomitant medication for the treatment of comorbid physical and psychiatric conditions. The five drugs, including an extended-release injectable suspension of naltrexone, have different safety profiles that need to be balanced with the treatment objective (initiation or continuation of abstinence, or reduction of drinking), individual patient preferences and comorbid conditions. Appropriate treatment will be based on the unique risk-benefit profile in each case. PMID:27023898

    Enzymes operate in a densely packed cellular environment that rarely matches the dilute conditions under which they are studied. To better understand the ramifications of this crowding, the Michaelis-Menten kinetics of yeast alcohol dehydrogenase (YADH) were monitored spectrophotometrically in the presence of high concentrations of dextran. Crowding decreased the maximal rate of the reaction by 40% for assays with ethanol, the primary substrate of YADH. This observation was attributed to slowed release of the reduced β-nicotinamide adenine dinucleotide product, which is rate-limiting. In contrast, when larger alcohols were used as the YADH substrate, the rate-limiting step becomes hydride transfer and crowding instead increased the maximal rate of the reaction by 20-40%. This work reveals the importance of considering enzyme mechanism when evaluating the ways in which crowding can alter kinetics.

    Objective Previously, we reported that the 5′-HTTLPR-LL and rs1042173-TT (SLC6A4-LL/TT) genotypes in the serotonin transporter gene predicted a significant reduction in the severity of alcohol consumption among alcoholics receiving the 5-HT3 antagonist ondansetron. In this study, we explored additional markers of ondansetron treatment response in alcoholics by examining polymorphisms in the HTR3A and HTR3B genes, which regulate directly the function and binding of 5-HT3 receptors to ondansetron. Method We genotyped 1 rare and 18 common single-nucleotide polymorphisms in HTR3A and HTR3B in the same sample that we had genotyped for SLC6A4-LL/TT in the previous randomized, double-blind, 11-week clinical trial. Participants were 283 European Americans who received oral ondansetron (4 μg/kg twice daily) or placebo along with weekly cognitive behavioral therapy. Associations of individual and combined genotypes with treatment response on drinking outcomes were analyzed. Results Individuals carrying one or more of genotypes rs1150226-AG and rs1176713-GG in HTR3A and rs17614942-AC in HTR3B showed a significant overall mean difference between ondansetron and placebo in drinks per drinking day (−2.50; effect size (ES)=0.867), percentage of heavy drinking days (−20.58%; ES=0.780), and percentage of days abstinent (18.18%; ES=0.683). Combining these HTR3A/HTR3B and SLC6A4-LL/TT genotypes increased the target cohort from approaching 20% (identified in our previous study) to 34%. Conclusions We present initial evidence suggesting that a combined 5-marker genotype panel can be used to predict the outcome of treatment of alcohol dependence with ondansetron. Additional, larger pharmacogenetic studies would help to validate our results. PMID:23897038

  17. Alcohol-Induced Blackout

    Dai Jin Kim

    2009-11-01

    Full Text Available For a long time, alcohol was thought to exert a general depressant effect on the central nervous system (CNS. However, currently the consensus is that specific regions of the brain are selectively vulnerable to the acute effects of alcohol. An alcohol-induced blackout is the classic example; the subject is temporarily unable to form new long-term memories while relatively maintaining other skills such as talking or even driving. A recent study showed that alcohol can cause retrograde memory impairment, that is, blackouts due to retrieval impairments as well as those due to deficits in encoding. Alcoholic blackouts may be complete (en bloc or partial (fragmentary depending on severity of memory impairment. In fragmentary blackouts, cueing often aids recall. Memory impairment during acute intoxication involves dysfunction of episodic memory, a type of memory encoded with spatial and social context. Recent studies have shown that there are multiple memory systems supported by discrete brain regions, and the acute effects of alcohol on learning and memory may result from alteration of the hippocampus and related structures on a cellular level. A rapid increase in blood alcohol concentration (BAC is most consistently associated with the likelihood of a blackout. However, not all subjects experience blackouts, implying that genetic factors play a role in determining CNS vulnerability to the effects of alcohol. This factor may predispose an individual to alcoholism, as altered memory function during intoxication may affect an individual‟s alcohol expectancy; one may perceive positive aspects of intoxication while unintentionally ignoring the negative aspects. Extensive research on memory and learning as well as findings related to the acute effects of alcohol on the brain may elucidate the mechanisms and impact associated with the alcohol- induced blackout.

    Aocoholism in the elderly determines tne protracted nature or tne pathological craving for etnanol in post-abstinence syndrome period, restricts arsenal of active pharmacotherapy and updates the search for new pharmacological therapeutic strategies. The results showed that the inclusion of the drug "Remaxol" in the treatment of clinical manifestations of craving for ethanol in post-abstinence syndrome period of associated forms of alcoholism in the elderly provides better in relation to conventional therapy dynamics of reduction of somatovegetative and neurological manifestations of alcohol withdrawal syndrome, as well as the main components of craving for alcohol, will increase the efficiency of outpatient treatment at the stage of remission. The duration of remission of mental and behavioral disorders caused by alcohol use in elderly patients is, apart from pharmacotherapy, due to such social and psychological factors and akmeological features as education, leadership potential, high social activity, a high level of social intelligence and its implementation, lack of intense intrapersonal conflict, high ductility and activity.

As drogas anticonvulsivantes clássicas são raramente empregadas como alternativa por causa dos seus efeitos colaterais, mas a sua última geração pode ser útil. Os anticonvulsivantes podem ser uma alternativa aos benzodiazepínicos (BZD e a outros tratamentos farmacológicos na prevenção de complicações na desintoxicação por apresentarem ausência de propriedades aditivas e um melhor perfil de efeitos adversos do que os anticonvulsivantes clássicos. Anticonvulsivantes como carbamazepina, ácido valpróico, gabapentina e topiramato demonstraram-se excelentes tratamentos para síndrome de abstinência do álcool e prevenção de recaídas. Embora nenhum desses agentes tenha sido aprovado pela FDA, existe uma crescente evidência na literatura que apóia o seu uso.Currently three medications (disulfiram, naltrexone and acamprosate are approved by the FDA to treat alcohol dependence by the FDA. The classical anticonvulsive drugs are rarely employed as an alternative because of their side effects, but the latest generation of anticonvulsants could be useful. The anticonvulsants can be a alternative to BZD and other pharmacological treatments in the prevention of complications during the detoxification therapy, because of the absence of addictive properties and a better adverse effects profile than classical anticonvulsant drugs. Anticonvulsants such as carbamazepine, valproic acid, gabapentin and topiramate have shown to be excellent treatment for alcohol withdrawal and for the prevention of alcohol relapse. Although none of these agents have been approved by the FDA yet, there is growing evidence in the literature to support their use.

  4. The Impact of Accelerated Right Prefrontal High-Frequency Repetitive Transcranial Magnetic Stimulation (rTMS on Cue-Reactivity: An fMRI Study on Craving in Recently Detoxified Alcohol-Dependent Patients.

    Full Text Available In alcohol-dependent patients craving is a difficult-to-treat phenomenon. It has been suggested that high-frequency (HF repetitive transcranial magnetic stimulation (rTMS may have beneficial effects. However, exactly how this application exerts its effect on the underlying craving neurocircuit is currently unclear. In an effort to induce alcohol craving and to maximize detection of HF-rTMS effects to cue-induced alcohol craving, patients were exposed to a block and event-related alcohol cue-reactivity paradigm while being scanned with fMRI. Hence, we assessed the effect of right dorsolateral prefrontal cortex (DLPFC stimulation on cue-induced and general alcohol craving, and the related craving neurocircuit. Twenty-six recently detoxified alcohol-dependent patients were included. First, we evaluated the impact of one sham-controlled stimulation session. Second, we examined the effect of accelerated right DLPFC HF-rTMS treatment: here patients received 15 sessions in an open label accelerated design, spread over 4 consecutive days. General craving significantly decreased after 15 active HF-rTMS sessions. However, cue-induced alcohol craving was not altered. Our brain imaging results did not show that the cue-exposure affected the underlying craving neurocircuit after both one and fifteen active HF-rTMS sessions. Yet, brain activation changes after one and 15 HF-rTMS sessions, respectively, were observed in regions associated with the extended reward system and the default mode network, but only during the presentation of the event-related paradigm. Our findings indicate that accelerated HF-rTMS applied to the right DLPFC does not manifestly affect the craving neurocircuit during an alcohol-related cue-exposure, but instead it may influence the attentional network.

    Background The few genetically informative studies to examine post-traumatic stress disorder (PTSD) and alcohol dependence (AD), all of which are based on a male veteran sample, suggest that the co-morbidity between PTSD and AD may be attributable in part to overlapping genetic influences, but this issue has yet to be addressed in females. Method Data were derived from an all-female twin sample (n=3768) ranging in age from 18 to 29 years. A trivariate genetic model that included trauma exposure as a separate phenotype was fitted to estimate genetic and environmental contributions to PTSD and the degree to which they overlap with those that contribute to AD, after accounting for potential confounding effects of heritable influences on trauma exposure. Results Additive genetic influences (A) accounted for 72 % of the variance in PTSD ; individual-specific environmental (E) factors accounted for the remainder. An AE model also provided the best fit for AD, for which heritability was estimated to be 71 %. The genetic correlation between PTSD and AD was 0.54. Conclusions The heritability estimate for PTSD in our sample is higher than estimates reported in earlier studies based almost exclusively on an all-male sample in which combat exposure was the precipitating traumatic event. However, our findings are consistent with the absence of evidence for shared environmental influences on PTSD and, most importantly, the substantial overlap in genetic influences on PTSD and AD reported in these investigations. Additional research addressing potential distinctions by gender in the relative contributions of genetic and environmental influences on PTSD is merited. PMID:21054919

    Alcohol dependence (AD) is a multifactorial and polygenic disorder involving complex gene-to-gene and gene-to-environment interactions. Several genome-wide association studies have reported numerous risk factors for AD, but replication results following these studies have been controversial. To identify new candidate genes, the present study used GWAS and replication studies in a Korean cohort with AD. Genome-wide association analysis revealed that two chromosome regions on Chr. 4q22-q23 (ADH gene cluster, including ADH5, ADH4, ADH6, ADH1A, ADH1B, and ADH7) and Chr. 12q24 (ALDH2) showed multiple association signals for the risk of AD. To investigate detailed genetic effects of these ADH genes on AD, a follow-up study of the ADH gene cluster on 4q22-q23 was performed. A total of 90 SNPs, including ADH1B rs1229984 (H47R), were genotyped in an additional 975 Korean subjects. In case-control analysis, ADH1B rs1229984 (H47R) showed the most significant association with the risk of AD (p = 2.63 × 10(-21), OR = 2.35). Moreover, subsequent conditional analyses revealed that all positive associations of other ADH genes in the cluster disappeared, which suggested that ADH1B rs1229984 (H47R) might be the sole functional genetic marker across the ADH gene cluster. Our findings could provide additional information on the ADH gene cluster regarding the risk of AD, as well as a new and important insight into the genetic factors associated with AD.

    2013-01-01

    The Balloon Analogue Risk Task (BART) is an experimental measure of risk taking that has commonly been employed to measure the risk taking behavior of nonclinical populations. Previous research has indicated that the task measures a unique aspect of behavioral disinhibition, but there has not as yet been focus upon the possible impact of other aspects of cognitive processing on performance. The current study investigated the cognitive factors related to performance of the BART in an alcohol-using sample. Seventeen individuals with long-term alcohol use were matched for age and education to a group of 17 nonusing participants. The results indicated that the alcohol-using group pumped the balloons on the BART to a lesser extent than did the nonusing group across all trials on the task. The results indicate that the alcohol-using group made less "optimal" decisions on the BART most notably due to neuropsychological impairment in the domains of immediate memory and executive functioning.

    Full Text Available Objective: To examine the factors influencing the pattern and extent of anti-craving medication adherence and drinking outcomes in alcohol-dependent patients. Materials and Methods: Demographic data from 102 inpatients were collected at discharge from hospital. The pattern of anti-craving medication, extent of adherence, and drinking outcome was collected at 1 st , 3 rd , 8 th , and 12 th week follow-up. Patients′ self-reported adherence, medication diary, and simplified medication adherence questionnaire were used and data were analyzed using SPSS. Results: Majority (99% were male patients with a mean age of 41.17 ± 9.86 years and 70% belonged to middle socioeconomic status. There was a decrease in the number of patients coming for follow-up over time from 99.01% to 77.45% on day 90. Acamprosate was used in 74% and naltrexone and disulfiram in 7% of patients each. A significant reduction in adherence to acamprosate and naltrexone (P < 0.001 was associated with simultaneous decrease in days to alcohol abstinence and increase in relapse rate compared to adherent group (P < 0.001. Main barriers to adherence included younger age (odds ratio = 1.05 95% [1.01-1.09]; P < 0.01, self-decision, emotional factors, and adverse effects. Conclusions: The study demonstrated the need for safer therapeutic options along with suitable intervention at "grass root level" for sustenance of adherence to anti-craving medication among young adults to prevent relapse and achieve near-complete abstinence from alcohol dependence.

    The purpose of this exploratory study was to examine the interaction of 5-HTTLPR and DRD4 exon III polymorphisms with gender in non-treatment seeking alcohol dependent (AD) individuals while alternately taking ondansetron and sertraline. Evidence suggests that alcohol dependence may be influenced by a genetic interaction that may be gender specific with temporal changes making pharmacological treatment with serotonergic drugs complex. The main trial was a within-subject double-blind placebo-controlled human laboratory study with 77 non-treatment-seeking AD individuals randomized (55 completed, 49 complete data) to receive 200mg/day of sertraline or 0.5mg/day of ondansetron for 3-weeks followed by an alcohol self-administration experiment (ASAE), then placebo for three weeks followed by a second ASAE, then receive the alternate drug, in a counterbalanced order, for three weeks followed by a third ASAE. Results for men were not significant. Women with the LL 5-HTTLPR genotype receiving ondansetron and SS/SL 5-HTTLPR genotypes receiving sertraline (matched), drank significantly fewer drinks per drinking day (DDD) during the 7-days prior to the first and third ASAEs than women receiving the mismatched medication (i.e. sertraline to LL and ondansetron to SS/SL). In a three-way interaction, 5-HTTLPR alleles by DRD4 alleles by medications, women with the LL genotype who received ondansetron and had DRD4 ≥7 exon III repeats drank significantly fewer DDD as did SS/SL women who received sertraline but conversely had DRD4 <7-repeats in the 7-day period leading up to the first and third ASAEs. Consistent with these data was a significant reduction of milliliters consumed ad lib during these same ASAEs. These exploratory findings add possible support to gender and genetic differences among AD individuals in response to serotonergic pharmacotherapies. Future trials should be powerful enough to take into account that endophenotypes and a targeting of serotonergic interactions

  18. The Combination of Marketed Antagonists of α1b-Adrenergic and 5-HT2A Receptors Inhibits Behavioral Sensitization and Preference to Alcohol in Mice: A Promising Approach for the Treatment of Alcohol Dependence.

    Fabrice Trovero

    Full Text Available Alcohol-dependence is a chronic disease with a dramatic and expensive social impact. Previous studies have indicated that the blockade of two monoaminergic receptors, α1b-adrenergic and 5-HT2A, could inhibit the development of behavioral sensitization to drugs of abuse, a hallmark of drug-seeking and drug-taking behaviors in rodents. Here, in order to develop a potential therapeutic treatment of alcohol dependence in humans, we have blocked these two monoaminergic receptors by a combination of antagonists already approved by Health Agencies. We show that the association of ifenprodil (1 mg/kg and cyproheptadine (1 mg/kg (α1-adrenergic and 5-HT2 receptor antagonists marketed as Vadilex ® and Periactine ® in France, respectively blocks behavioral sensitization to amphetamine in C57Bl6 mice and to alcohol in DBA2 mice. Moreover, this combination of antagonists inhibits alcohol intake in mice habituated to alcohol (10% v/v and reverses their alcohol preference. Finally, in order to verify that the effect of ifenprodil was not due to its anti-NMDA receptors property, we have shown that a combination of prazosin (0.5 mg/kg, an α1b-adrenergic antagonist, Mini-Press ® in France and cyproheptadine (1 mg/kg could also reverse alcohol preference. Altogether these findings strongly suggest that combined prazosin and cyproheptadine could be efficient as a therapy to treat alcoholism in humans. Finally, because α1b-adrenergic and 5-HT2A receptors blockade also inhibits behavioral sensitization to psychostimulants, opioids and tobacco, it cannot be excluded that this combination will exhibit some efficacy in the treatment of addiction to other abused drugs.

    Conflicting reports exist on the direction of the relationship between social anxiety (SA) and alcohol/cigarette use (AU/CU) and alcohol/nicotine dependence (AD/ND), with both positive and negative associations reported. A prospective, longitudinal sample of Finnish twins (n = 1,906) was used to test potential explanations for these discrepancies. Specifically, this study used peer, parent, and teacher ratings of SA, and a clinical interview screening item for social anxiety disorder (SAD-Sc) to examine associations between SA and AU/CU and AD/ND from early adolescence into young adulthood. Peer-rated SA was negatively associated with AU, CU, and AD from age 14 through age 22, implying a protective effect (β = -0.01 to -.03). Teacher- and parent-rated SA associations were in the same directions but weaker or nonsignificant, indicating that aspects of SA that are recognizable by peers may be most relevant to AU/CU. Self-reported SAD-Sc was also negatively associated with AU, but positively associated with AD symptoms in young adulthood (β = 0.38). Our findings partially support the existence of different associations between SA and AU versus AD, but only in the context of SAD-Sc rather than trait SA. Neither trait SA nor SAD-Sc significantly predicted ND symptoms, although SAD-Sc was associated with both cigarette abstinence and daily smoking. These findings suggest that adolescent SA is modestly associated with lower AU/CU, although there may be some individuals with more severe SA who develop alcohol problems later in life. There was little evidence of a common underlying liability contributing to both SA and alcohol/cigarette use. (PsycINFO Database Record PMID:27322804

    International audience Objectives: Craving plays an important role in the development and maintenance of alcohol dependence and in relapse after periods of abstinence. Anti-craving compounds, such as acamprosate, naltrexone or serotonergic compounds, are found to be only moderately effective. These moderate effects might be due to inadequate matching of specific patients to specific treatments. In 1999, Verheul et al. proposed a three-pathway model of craving in alcoholics, which hypothesi...

    Alcohol is widely consumed, but excessive use creates serious physical, psychological and social problems and contributes to many diseases. Alcoholism (alcohol dependence, alcohol use disorders) is a maladaptive pattern of excessive drinking leading to serious problems. Abundant evidence indicates that alcoholism is a complex genetic disease, with variations in a large number of genes affecting risk. Some of these genes have been identified, including two genes of alcohol me...

    The set of alcohol-metabolizing enzymes has considerable genetic and functional complexity. The relationships between some alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) genes and alcohol dependence (AD) have long been studied in many populations, but not comprehensively. In the present study, we genotyped 16 markers within the ADH gene cluster (including the ADH1A, ADH1B, ADH1C, ADH5, ADH6, and ADH7 genes), 4 markers within the ALDH2 gene, and 38 unlinked ancestry-informative markers in a case-control sample of 801 individuals. Associations between markers and disease were analyzed by a Hardy-Weinberg equilibrium (HWE) test, a conventional case-control comparison, a structured association analysis, and a novel diplotype trend regression (DTR) analysis. Finally, the disease alleles were fine mapped by a Hardy-Weinberg disequilibrium (HWD) measure (J). All markers were found to be in HWE in controls, but some markers showed HWD in cases. Genotypes of many markers were associated with AD. DTR analysis showed that ADH5 genotypes and diplotypes of ADH1A, ADH1B, ADH7, and ALDH2 were associated with AD in European Americans and/or African Americans. The risk-influencing alleles were fine mapped from among the markers studied and were found to coincide with some well-known functional variants. We demonstrated that DTR was more powerful than many other conventional association methods. We also found that several ADH genes and the ALDH2 gene were susceptibility loci for AD, and the associations were best explained by several independent risk genes. PMID:16685648

    Alexithymia is a multifaceted personality trait that involves difficulties in identifying and describing feelings to others, a poor fantasy life and an externally oriented cognitive style. Alexithymia has been described as a vulnerability factor for mental and physical diseases. We investigated in a group of 158 alcohol-dependent patients (103 men, 55 women) the association between depression and craving for alcohol when these patients were starting a detoxification program, and the moderating impact of gender and alexithymia on this relation. We first found an interaction between depression and gender in the prediction of craving in the sense that only for women an increase in depressive mood was related to an increase in total craving. When examining gender separately, we found that alexithymia factors acted as moderators. For women, the link between depression and craving was strengthened for the ones scoring higher on "difficulties describing feelings". But for men, the link between depression and craving was reduced for the ones scoring higher on "externally-oriented thinking". These findings suggest that in some cases that need to be identified more systematically in the future, the "externally-oriented thinking" alexithymia factor can exert - at least in the short term - some protective effects.

    The majority of people with alcohol use disorders do not seek formal treatment. Research on barriers to help-seeking have only recently focused on ethnic minority populations. The present study investigated the extent to which an adult American Indian (AI) sample experienced similar and/or unique barriers to help-seeking as have been reported in the literature. Using both qualitative and quantitative methods, 56 (54% male) AIs with lifetime alcohol dependence completed a semistructured face-to-face interview and a self-administered written survey. Interviews were tape recorded, transcribed, and coded for four major themes: personal barriers, pragmatic barriers, concerns about seeking help, and social network barriers. Quantitative data provided percentage endorsing each survey item and strength of each barrier, which were categorized according to the four major themes. In previous research, most barriers questionnaires have not queried for cultural concerns or how the specific type of help may be a mismatch from the client's perspective. Given the rapidly changing racial/ethnic demography in the United States, further research addressing cultural and spiritual concerns as well as more common barriers is indicated.

    Full Text Available Abstract Background There is increasing recognition that perinatal common mental disorders (PCMDs are prevalent in women in low and lower-middle income countries and emerging evidence that PCMDs and alcohol abuse occur in men in these settings. Domestic violence is associated with PCMDs in both women and men. The aim of this study was to examine the relationships among PCMDs, alcohol abuse and domestic violence in couples in a rural, low-income setting. Methods A cross-sectional, population-based study was undertaken in randomly selected communes in Ha Nam and Hanoi, Vietnam. All women in the selected study sites who were at least 28 weeks pregnant or were mothers of 4 – 6 week old babies in the recruitment period were eligible. The husbands of the women who consented to join the study were also invited to participate. Data sources were study-specific questions and standardised measures: PCMDs were assessed by psychiatrist-administered Structured Clinical Interviews for DSM IV disorders, and alcohol dependence (AD by the CAGE questionnaire (cut-off of ≥ 2. Structural Equation Modeling was used to test direct, indirect and mutual relationships simultaneously in the hypothesised model. Results In total 364/392 (93% eligible women agreed to participate. Of these, 360 were married, and 230 (64% of their husbands also participated to yield a sample of 230 couples for analyses. Overall, in 7.4% (95% CI: 4.6-11.6 of couples both wife and husband were diagnosed with a PCMD; and 41.2% (95% CI: 35.1-47.8 of couples at least one member had a PCMD. Comorbid PCMD and AD were observed in 6.9% (95% CI: 4.3-11.0 of men, but did not occur in women. After controlling for other psychosocial risk factors comorbid PCMD and AD in husbands increased by 4.7 times the probability of PCMDS in their wives via intimate partner violence. PCMDS in wives did not increase the probability of PCMDS or AD in husbands. Conclusions These data provide evidence that comorbid

    The purpose of this study was to compare the cost-effectiveness of conventional outpatient treatment for alcoholic patients (CT) with this same conventional treatment plus home visits (HV), a new proposal for intervention within the Brazilian outpatient treatment system. A cost-effectiveness evaluation alongside a 12-week randomized clinical trial was performed. We identified the resources utilized by each intervention, as well as the cost according to National Health System (SUS), Brazilian Medical Association (AMB) tables of fees, and others based on 2005 data. The incremental cost-effectiveness ratio (ICER) was estimated as the main outcome measure - abstinent cases at the end of treatment. There were 51.8% abstinent cases for HV and 43.1% for CT, a clinically relevant finding. Other outcome measures, such as quality of life, also showed significant improvements that favored HV. The baseline scenario presented an ICER of USD 1,852. Sensitivity analysis showed an ICER of USD 689 (scenario favoring HV) and USD 2,334 (scenario favoring CT). The HV treatment was found to be cost-effective according to the WHO Commission on Macroeconomics and Health. PMID:20029212

    This paper reports an evaluation of a community-based approach to prevent underage sales of alcohol. The interventions focused on (a) enforcement of underage sales laws, (b) responsible beverage service (RBS) training and (c) media advocacy. The interventions were implemented in three experimental communities located in California and South Carolina. Purchase survey data were obtained before and after the interventions in each experimental community and in three matched comparison communities. Logistic regression analyses of the purchase survey data for the individual community pairs and for the combined communities showed that sales to apparent minors were significantly reduced in the experimental sites. The findings indicate that these environmental interventions are promising prevention tools for communities that seek to reduce underage drinking. PMID:9231448

    Full Text Available The aim of the article was to assess how the perception of alcohol craving, which is one of the symptoms of alcohol dependence, evolved, as well as how it was reflected in the diagnostic classifications. The purpose of this article was also a discussion of the models of the origins of craving, explaining the etiology of this phenomenon and the tools for measuring this concept. The concept of craving, defined as a strong need or compulsion to drink alcohol, functioned for many years, not only in the clinical practice but also as a concept inherently associated with alcohol dependence. However, among experts and researchers, there was no consensus about the etiology of this phenomenon and its development. Some emphasize the emotional – motivational aspect of it, while in the literature also its cognitive – behavioral nature is highlighted. Craving as a symptom has been recognized as a diagnostic criterion of alcohol dependence in the International Statistical Classification of Diseases and Related Health Problems – ICD 10. In the year 2013, it was also indicated as a symptom of disorder resulting from alcohol abuse in the Diagnostic and Statistical Manual of Mental Disorders – DSM 5. It seems to be significant also to discuss the tools used to measure craving, both in clinical trials and therapeutic practice, among them: the Alcohol Specific Role Play Test, Obsessive Compulsive Drinking Scale (OCDS Lubeck Craving Scale (LCRR and Alcohol Urge Questionnaire (AUQ.

    Background One hypothesis suggests that the differential response to ondansetron and serotonin specific re-uptake inhibitors (SSRIs) may be due to a functional polymorphism of the 5′-HTTLPR promoter region in SLC6A4, the gene that codes for the serotonin transporter (5-HTT). The LL 5′-HTTLPR genotype is postulated to be specifically sensitive to the effects of ondansetron with SS/SL 5′-HTTLPR genotypes sensitive to SSRIs. This study tests this hypothesis by matching non-treatment seeking alcohol dependent (AD) individuals with LL genotype to ondansetron and SS/SL genotypes to the SSRI sertraline, and mis-matching them assessing naturalistic and bar-laboratory alcohol drinking. Methods Seventy-seven AD individuals were randomized to one of two counterbalanced arms to receive sertraline 200mg/day or ondansetron 0.5 mg/day for three weeks followed by an alcohol self-administration experiment (ASAE), then received placebo for three weeks followed by a second ASAE. Individuals then received the alternate drug for three weeks followed by a third ASAE. Drinks per drinking day (DDD with drinks in SDUs) for 7 days prior to each ASAE and milliliters consumed during each ASAE were the primary outcomes. Results Fifty-five participants completed the study. The genotype x order interaction was significant [F(1,47) = 8.42, p = .006] for DDD. Three ANCOVAs were conducted for DDD during the week before each ASAE. Ondansetron compared to sertraline resulted in a significant reduction in DDD during the week before the first [F(1,47) = 7.64, p = .008] but not the third ASAE. There was no difference in milliliters consumed during each ASAE. Conclusion This study modestly supports the hypothesis that ondansetron may reduce DDD in AD individuals with the LL genotype as measured naturalistically. By contrast there was no support that ondansetron reduces drinking during the ASAEs or that sertraline reduces alcohol use in individuals who have SS/SL genotypes. We provide limited

    Recent studies have shown that smoking and alcoholism may be associated with altered DNA methylation and that alcohol consumption might induce changes in DNA methylation by altering homocysteine metabolism. In this monocenter study, we included 363 consecutive patients referred for hospitalization for alcohol detoxification treatment. Blood samples were obtained on treatment days 1, 3, and 7 for measurement of global DNA methylation in leukocytes by liquid chromatography tandem mass spectrometry. Genomic DNA was used for genotyping the following seven genetic variants of homocysteine metabolism: cystathionine beta-synthase (CBS) c.844_855ins68, dihydrofolate-reductase (DHFR) c.594 + 59del19bp, methylenetetrahydrofolate-reductase (MTHFR) c.677C > T and c.1298A > C, methyltetrahydrofolate-transferase (MTR) c.2756A > G, reduced folate carrier 1 (RFC1) c.80G > A, and transcobalamin 2 c.776C > G. Multivariate linear regression showed a positive correlation of global DNA methylation with alcohol consumption and smoking on day 1 of hospitalization. DNA methylation was not correlated with homocysteine or vitamin plasma levels, nor with the tested genetic variants of homocysteine metabolism. This suggests a direct effect of alcohol consumption and smoking on DNA methylation, which is not mediated by effects of alcohol on homocysteine metabolism.

    Alcohol addiction may increase the risk of obesity due to shared genetic components. The Copine V (CPNE5) gene is involved in Ca(2+) binding and may play an important role in the development of the central nervous system. This study tested the genetic associations of 77 single-nucleotide polymorphisms (SNPs) within the CPNE5 gene with alcohol dependence (AD) and obesity using a Caucasian sample - The Study of Addiction - Genetics and Environment (SAGE) sample (1066 AD cases and 1278 non-AD controls, 422 obese cases and 1395 non-obese controls). The Marshfield sample (1442 obese cases and 2122 non-obese controls) was used for replication of obesity. Multiple logistic regression analysis was performed using the PLINK software. In the SAGE sample, we identified 10 SNPs associated with AD and 17 SNPs associated with obesity (p obesity (OR = 0.77, 0.77, 0.78, 0.77, 0.68 and 1.18, respectively; p = 2.74 × 10(-3), 2.69 × 10(-3), 2.45 × 10(-3), 1.01 × 10(-3), 5.18 × 10(-3) and 3.85 × 10(-2), respectively). In the Marshfield sample, rs3752480 was associated with obesity (p = 0.0379). In addition, four SNPs (rs9986517, rs10456444, rs7763347 and rs4714010) showed associations with obesity in the meta-analysis using both samples (p = 0.00493, 0.0274, 0.00346, and 0.0141, respectively). These findings provide the first evidence of common genetic variants in the CPNE5 gene influencing both the AD and obesity; and will serve as a resource for replication in other populations.

    Objective We identify drinking styles that place teens at greatest risk of later alcohol use disorders (AUD). Design Population-based cohort study. Setting Victoria, Australia. Participants A representative sample of 1943 adolescents living in Victoria in 1992. Outcome measures Teen drinking was assessed at 6 monthly intervals (5 waves) between mean ages 14.9 and 17.4 years and summarised across waves as none, one, or two or more waves of: (1) frequent drinking (3+ days in the past week), (2) loss of control over drinking (difficulty stopping, amnesia), (3) binge drinking (5+ standard drinks in a day) and (4) heavy binge drinking (20+ and 11+ standard drinks in a day for males and females, respectively). Young Adult Alcohol Use Disorder (AUD) was assessed at 3 yearly intervals (3 waves) across the 20s (mean ages 20.7 through 29.1 years). Results We show that patterns of teen drinking characterised by loss of control increase risk for AUD across young adulthood: loss of control over drinking (one wave OR 1.4, 95% CI 1.1 to 1.8; two or more waves OR 1.9, CI 1.4 to 2.7); binge drinking (one wave OR 1.7, CI 1.3 to 2.3; two or more waves OR 2.0, CI 1.5 to 2.6), and heavy binge drinking (one wave OR 2.0, CI 1.4 to 2.8; two or more waves OR 2.3, CI 1.6 to 3.4). This is not so for frequent drinking, which was unrelated to later AUD. Although drinking was more common in males, there was no evidence of sex differences in risk relationships. Conclusions Our results extend previous work by showing that patterns of drinking that represent loss of control over alcohol consumption (however expressed) are important targets for intervention. In addition to current policies that may reduce overall consumption, emphasising prevention of more extreme teenage bouts of alcohol consumption appears warranted. PMID:26868948

    Episodic mood disorders are often associated with alcohol dependence. Few studies have explored the contribution of episodic mood disorders to length of stay among those hospitalized with alcohol dependence syndrome. Filling this research gap could improve care for patients while minimizing hospital utilization costs. This study was a cross-sectional analysis of the National Hospital Discharge Survey. ICD-9-CM diagnosis codes were used to identify those admitted to a private or non-profit hospital with alcohol dependence syndrome, and a co-morbid diagnosis of an episodic mood disorder (n=358). Descriptive statistics were used to highlight differences in key demographic and hospital variables between those with and without episodic mood disorders. Negative binomial regression was used to associate episodic mood disorders with hospital length of stay. Incidence rate ratios were calculated. Co-morbid episodic mood disorders (β=0.31, P=0.001), referral to a hospital by a physician (β=0.35, P=0.014), and increasing age (β= 0.01, P=0.001) were associated with longer hospital stays. Hospital patients with an admitting diagnosis of alcohol dependence syndrome were 36% more likely to have a longer hospital stay if they also had a co-morbid diagnosis of an episodic mood disorder (IRR=1.36, CI=1.14-1.62). Patients admitted to a hospital with alcohol dependence syndrome should be routinely screened for episodic mood disorders. Opportunities exist for enhanced transitional care between acute, ambulatory, and community-based care settings to lower hospital utilization.

    Full Text Available The production of monoacylglycerol rich in polyunsaturated fatty acids (PUFA via enzymatic glycerolysis of sardine oil in a homogeneous system was evaluated. Reactions were conducted in two different tert-alcohols. Based on the phase equilibrium data, the amount of solvent added to create a homogeneous system has been calculated and optimized. The immobilized lipase used in this work was Lipozyme RM IM from Rhizomucor miehei, a water dependent lipase. The amount of water added as well as other reaction parameters were studied to evaluate the optimum conditions for monoacylglycerol obtencion. An initial reactant mole ratio glycerol to sardine oil 3:1, 12 wt% of water based on glycerol content and 10 wt% of lipase loading (based on weight of reactants, achieved a MAG yield of around 70%, with nearly 28 wt% PUFA, with low free fatty acid content (lower than 18 wt%.En este trabajo se ha estudiado la producción de monoacilglicéridos, ricos en ácidos grasos poliinsaturados (AGPI, mediante glicerolisis enzimática de aceite de sardina.

    2006-01-01

    The gas phase reactions of metal plasma with alcohol clusters were studied by time of flight mass spectrometry(TOFMS) using laser ablation-molecular beam (LAMB) method. The significant dependence of the product cluster ions on the molecular beam conditions was observed. When the plasma acted on the low density parts of the pulsed molecular beam, the metal-alcohol complexes M+An (M=Cu, Al, Mg, Ni and A=C2H5OH, CH3OH) were the dominant products, and the sizes of product ion clusters were smaller. While the plasma acted on the high density part of the beam, however, the main products turned to be protonated alcohol clusters H+An and, as the reactions of plasma with methanol were concerned, the protonated water-methanol complexes H3O+(CH3OH)n with a larger size(n≤ 12 for ethanol and n≤24 for methanol). Similarly, as the pressure of the carrier helium gas was varied from1 × 105 to 5 × 105 Pa, the main products were changed from M+An to H+An and the sizes of the clusters also increased. The changes in the product clusters were attributed to the different formation mechanism of the output ions,that is, the M+An ions came from the reaction of metal ion with alcohol clusters, while H+An mainly from collisional reaction of electron with alcohol clusters.

    Full Text Available Although the introduction of alcohol based products have increased compliance with hand hygiene in intensive care units (ICU, no comparative studies with other products in the same unit and in the same period have been conducted. We performed a two-month-observational prospective study comparing three units in an adult ICU, according to hand hygiene practices (chlorhexidine alone-unit A, both chlorhexidine and alcohol gel-unit B, and alcohol gel alone-unit C, respectively. Opportunities for hand hygiene were considered according to an institutional guideline. Patients were randomly allocated in the 3 units and data on hand hygiene compliance was collected without the knowledge of the health care staff. TISS score (used for measuring patient complexity was similar between the three different units. Overall compliance with hand hygiene was 46.7% (659/1410. Compliance was significantly higher after patient care in unit A when compared to units B and C. On the other hand, compliance was significantly higher only between units A (32.1% and C (23.1% before patient care (p=0.02. Higher compliance rates were observed for general opportunities for hand hygiene (patient bathing, vital sign controls, etc, while very low compliance rates were observed for opportunities related to skin and gastroenteral care. One of the reasons for not using alcohol gel according to health care workers was the necessity for water contact (35.3%, 12/20. Although the use of alcohol based products is now the standard practice for hand hygiene the abrupt abolition of hand hygiene with traditional products may not be recommended for specific services.

    2016-09-01

    The effects of alcohol on induction of arrhythmias is dose-dependent, independent of preexisting cardiovascular diseases or heart failure and can affect otherwise healthy subjects. While the probability of atrial fibrillation increases with the alcohol dosage, events of sudden cardiac death are less frequent with low and moderate consumption but occur more often in heavy drinkers with alcoholic cardiomyopathy. Men are first affected at higher dosages of alcohol but women can suffer from arrhythmias at lower dosages. Thromboembolisms and ischemic stroke can occur less often at lower dosages of alcohol; however, hemorrhagic stroke and subarachnoid hemorrhage are increased with higher alcohol dosages. Recognizable protective mechanisms of alcohol with respect to cardiovascular diseases only occur with lower amounts of alcohol of less than 10 g per day. Underlying mechanisms explain these controversial effects. Specific therapeutic options for alcohol-related arrhythmias apart from abstinence from alcohol consumption are not known. PMID:27582366

    2012-01-01

    Objective To investigate the association of metabotropic glutamate receptor 3 (CRM3) gene polymorphisms and alcohol dependence in a Han Chinese population in northern China. Methods Polymerase chain reaction (PCR) and ligase detection reaction (LDR) were used to detect 3 single-nucleotide polymorphisms (SNPs) rsl468412, rs917071 and rsl989796 on metabotropic glutamate receptor 3 gene in 100 patients with alcohol dependence and 100 controls. Results There was no significant difference between the alcohol dependence group and the control group in the allele frequency and genotype distribution of those three SNPs. Haplotype TIT constructed by those three SNPs loci rs1468412-rs917071-rsl989796 was positively associated with the incidence of alcohol dependence (AD group 6%, control group 1%, OR = 5.17, P < 0.05). The possibility of alcohol dependence was higher in the patients carrying TIT genotype than in the controls. Conclusion The present study has not revealed any association between each SNP (rsl468412, rs917071, and rsl989796) of the GRM3 gene and alcohol dependence in this northern Chinese Han population. However, The haplotype TIT constructed by the three SNPs is positively associated with alcohol dependence, indicating that GRM3 may be a susceptible factor of alcohol dependence in northern Chinese Han population.%目的 探讨中国北方汉族人群代谢型谷氨酸受体3 (GRM3)基因多态性与酒依赖的相关性.方法 采用聚合酶链反应(Polymerase Chain Reaction,PCR)和连接酶检测反应(Ligase Detection Reaction,LDR)方法,检测100例酒依赖患者和100例正常对照的GRM3基因上3个位点rs1468412、rs917071和rs1989796的基因多态性.结果 酒依赖组和对照组之间GRM3基因rs1468412、rs917071以及rs1989796位点的等位基因频率和基因型分布的差异均无统计学意义(P>0.05),但酒依赖组中rs1468412、rs917071和rs19897963个位点所构建的单倍型TTT的频率明显高于对照组(6% vs.1%,OR=5

    Alcohol dependence (AD) is among the most common and costly public health problems contributing to morbidity and mortality throughout the world. In this study, we investigate the genetic basis of AD in a Dutch population using data from the Netherlands Twin Register (NTR) and the Netherlands Study of Depression and Anxiety (NESDA). The presence of AD was ascertained via the Alcohol Use Disorders Identification Test (AUDIT) applying cut-offs with good specificity and sensitivity in identifying those at risk for AD. Twin-based heritability of AD-AUDIT was estimated using structural equation modeling of data in 7,694 MZ and DZ twin pairs. Variance in AD-AUDIT explained by all SNPs was estimated with genome-wide complex trait analysis (GCTA). A genome-wide association study (GWAS) was performed in 7,842 subjects. GWAS SNP effect concordance analysis was performed between our GWAS and a recent AD GWAS using DSM-IV diagnosis. The twin-based heritability of AD-AUDIT was estimated at 60% (55-69%). GCTA showed that common SNPs jointly capture 33% (SE = 0.12, P = 0.002) of this heritability. In the GWAS, the top hits were positioned within four regions (4q31.1, 2p16.1, 6q25.1, 7p14.1) with the strongest association detected for rs55768019 (P = 7.58 × 10(-7) ). This first GWAS of AD using the AUDIT measure found results consistent with previous genetic studies using DSM diagnosis: concordance in heritability estimates and direction of SNPs effect and overlap with top hits from previous GWAS. Thus, the use of appropriate questionnaires may represent cost-effective strategies to phenotype samples in large-scale biobanks or other population-based datasets. PMID:26365420

    Full Text Available OBJECTIVE: To determine prevalence rates and identify patient characteristics associated with depression, alcohol use disorders and nicotine dependence among individuals admitted to a general teaching hospital. METHOD: Using the Hospital Anxiety and Depression Scale and Alcohol Use Disorder Identification Test, we assessed 4,352 consecutive medical and surgical patients admitted over a 13-month period. The patients were also asked to report their daily cigarette smoking habits during the last month. Multiple logistic regression analyses were performed, and odds ratios (ORs were calculated. RESULTS: The mean age of the sample was 49.3 years, and 56.6% were male. Prevalence rates of depression, alcohol use disorders and nicotine dependence were, respectively, 14%, 9.8% and 16.9%. In the multivariate analysis, depression was associated with previous suicide attempts (OR = 8.7, lower level of education (OR = 3.6, prior use of psychotropic medications (OR = 3.1, cancer (OR = 1.7 and pain (OR = 1.7. Alcohol use disorders were associated with male sex (OR = 6.3, smoking (OR = 3.5, admission for an external cause of injury, such as a traffic accident (OR = 2.4, and previous suicide attempts (OR = 2.3. Nicotine dependence was associated with alcohol use disorders (OR = 3.4, young adulthood (OR = 2.3, widowhood (OR = 2.2 and previous suicide attempts (OR = 1.8. CONCLUSION: This is the largest sample of medical and surgical patients ever surveyed with standardized screening instruments in a general hospital in Brazil. The high prevalence rates of psychiatric disorders and the profiles of the patients evaluated in this study underscore the need to develop methods that are more effective for detecting and managing such disorders. Hospital admission should be considered a major opportunity for the detection of psychiatric disorders and the subsequent implementation of the appropriate specific treatment strategies.OBJETIVO: Identificar taxas de prevalência e

    Full Text Available Objective:to describe the causes and severities of trauma in patients who met the criteria for alcohol abuse or dependence according to Mini International Neuropsychiatric Interview, and to display the pattern of alcohol consumption and subsequent changes one year after trauma.Methods:a transversal and longitudinal quantitative study carried out between November 2012 and September 2013 in the ED. Medical and nursing students collected blood samples, applied the J section of the Mini International Neuropsychiatric Interview (MINI and submitted alcohol abusers and dependents to BI. One year after admission, patients were contacted and asked about their patterns of alcohol use and their reasons for any changes.Results:from a sample of 507 patients admitted to the ED for trauma, 348 responded to MINI, 90 (25.9% being abusers and 36 (10.3% dependent on alcohol. Among the abusers, the most frequent cause of injury was motorcycle accident (35.6% and among the dependents it was predominantly interpersonal violence (22.2%. Positive blood samples for alcohol were identified in 31.7% of the abusers and 53.1% of the dependents. One year after trauma, 66 abusers and 31 dependents were contacted, and it was ascertained that 36.4% of the abusers and 19.4% of the dependents had decreased alcohol consumption. The main reported reason for the reduction was the experienced trauma.Conclusion:the motorcycle accident was the most common cause of injury. The detection of problematic alcohol use and implementation of BI are important strategies in the ED, however for alcohol abusers and dependents, BI was not the most reported reason for any changes in patterns of alcohol use.

    We examined predictors for age at onset of first alcohol use and onset of heaviest alcohol use among men (n = 43) and women (n = 46) with alcohol dependence and PTSD, PTSD only, alcohol dependence only, and controls, with a particular focus on individuals with child versus adult trauma. Using analysis of variance procedures, results showed differences in onset of first alcohol use and heaviest drinking between childhood and adulthood trauma victims. These preliminary results indicate that behavioral mechanisms associated with alcohol use patterns between individuals with childhood and adulthood trauma are dissimilar, suggesting greater psychopathological consequences for individuals with childhood trauma.

    Dielectric and conductivity behaviors of nano ZnO doped polyvinyl alcohol (PVA) composites for various concentrations of dopant were investigated using impedance spectroscopy for a wide range of temperatures (303 K-423 K) and frequencies (5 Hz-30 MHZ). The dielectric properties of host polymer matrix have been improved by the addition of nano ZnO and are found to be highly temperature dependent. Anomalous dielectric behavior was observed in the frequency range of 2.5 MHz-5 MHz. Increase in dielectric permittivity and dielectric loss was observed with respect to temperature. The Cole-Cole plot could be modeled by low resistance regions in a high resistance matrix and the lowest resistance was observed for the 10 mol. % films. The imaginary part of the electric modulus showed asymmetric peaks with the relaxation following Debye nature below and non-Debye nature above the peaks. The ac conductivity is found to obey Jonscher's power law, whereas the variation of dc conductivity with temperature was found to follow Arrhenius behavior. Two different activation energy values were obtained from Arrhenius plot indicating that two conduction mechanisms are involved in the composite films. Fitting the ac conductivity data to Jonscher's law indicates that large polaron assisted tunneling is the most likely conduction mechanism in the composites. Maximum conductivity is observed at 423 K for all the samples and it is optimum for 10 mol. % ZnO doped PVA composite film. Significant increase in dc and ac conductivities in these composite films makes them a potential candidate for application in electronic devices.

This study aimed at determining the prevalence of alcohol consumption in a southern Brazilian municipality and at investigating associated factors. METHODS: A cross-sectional population-based survey was carried out in the municipality of Rio Grande, southern Brazil, with a sample of 1,044 people, both male and female, aged 12 to 75 years. Alcohol dependence was defined according to the CAGE questionnaire, and alcohol abuse was defined as the daily consumption of at least 30 grams of alcohol for men and 24 grams for women. Potential confounding factors were controlled in the multivariate analysis (logistic regression. RESULTS: Alcohol abuse was found in 5.5% of the sample, and dependence in 2.5%. After adjusting for confounding factors, a significant association was observed between alcohol consumption and the following variables: male gender (odd ratio - OR = 6.28, smoking (OR = 5.42, and social class E (OR = 5.37. CONCLUSION: Our results revealed the difficulties involved in the performance of a population-based study to assess alcohol consumption and showed that men who smoke and come from lower-income groups have greater chances of presenting alcohol-related problems.

  16. Long-lasting alterations in membrane properties, K+ currents and glutamatergic synaptic currents of nucleus accumbens medium spiny neurons in a rat model of alcohol dependence

    Full Text Available Chronic alcohol exposure causes marked changes in reinforcement mechanisms and motivational state that are thought to contribute to the development of cravings and relapse during protracted withdrawal. The nucleus accumbens (NAcc is a key structure of the mesolimbic dopaminergic reward system. Although the NAcc plays an important role in mediating alcohol-seeking behaviors, little is known about the molecular mechanisms underlying alcohol-induced neuroadaptive changes in NAcc function. The aim of this study was to investigate the effects of chronic intermittent ethanol (CIE treatment, a rat model of alcohol withdrawal and dependence, on intrinsic electrical membrane properties and glutamatergic synaptic transmission of medium spiny neurons (MSNs in the NAcc core during protracted withdrawal. We show that CIE treatment followed by prolonged withdrawal increased the inward rectification of MSNs observed at hyperpolarized potentials. In addition, MSNs from CIE-treated animals displayed a lower input resistance, faster action potentials (APs and larger fast afterhyperpolarizations (fAHPs than MSNs from vehicle-treated animals, all suggestive of increases in K+-channel conductances. Significant increases in the Cs+-sensitive inwardly-rectifying K+-current accounted for the increased input resistance, while increases in the A-type K+-current accounted for the faster APs and increased fAHPs in MSNs from CIE rats. We also show that the amplitude and the conductance of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR-mediated mEPSCs were enhanced in CIE-treated animals due to an increase in a small fraction of functional postsynaptic GluA2-lacking AMPARs. These long-lasting modifications of excitability and excitatory synaptic receptor function of MSNs in the NAcc core could play a critical role in the neuroadaptive changes underlying alcohol withdrawal and dependence.

    Oxidative stress is induced by the accumulation of free radicals, resulting in an imbalanced cellular redox state, which has been implicated in a variety of human diseases. Dehydrodiconiferyl alcohol (DHCA), a lignan compound isolated from Cucurbita moschata, has previously been reported to contain anti-adipogenic and anti-lipogenic effects on 3T3-L1 cells and primary MEFs (Abraham and Kappas, 2008). In this study, it was tested whether DHCA could affect the expression of HO-1, using Raw264.7 mouse macrophage cell line. DHCA increased the protein and RNA levels of HO-1 and upregulated its promoter activity. Data from transient transfection assays indicated that ARE located in the E1 region of the HO-1 promoter are important in this DHCA-mediated induction of HO-1 expression. DHCA was also shown to enhance the nuclear translocation and binding of Nrf2 to the respective DNA sequences. The upregulation of HO-1 expression by DHCA was also observed in primary macrophages derived from wild type animals, but not in those from Nrf2 KO mice. Effects of DHCA on HO-1 and Nrf2 were reduced when cells were treated with an AMPK inhibitor, Compound C, but not by PI3K/Akt or MAPK inhibitors. Data from an experiment using a specific siRNA or chemical inhibitor for HO-1 suggested that the DHCA-mediated induction of the HO-1 protein could suppress the LPS-stimulated production of NO. Taken together, our data suggest that DHCA induces the expression of HO-1 by controlling its promoter activity through the AMPK–Nrf2 pathway, eventually leading to the reduction of NO production, and may thus have potential as an effective antioxidant. - Highlights: • Dehydrodiconiferyl alcohol (DHCA) induced the expression of heme oxygenase (HO)-1. • The AMPK–Nrf2 pathway is critically involved in the DHCA-mediated induction of HO-1. • DHCA increased the expression of HO-1, Gclc and Gclm in primary macrophages. • DHCA-mediated induction of HO-1 contributed to the suppression of NO production.

    An association between chronic pain conditions and alcohol dependence has been revealed in numerous studies with episodes of alcohol abuse antedating chronic pain in some people and alcohol dependence emerging after the onset of chronic pain in others. Alcohol dependence and chronic pain share common neural circuits giving rise to the possibility that chronic pain states could significantly affect alcohol use patterns and that alcohol dependence could influence pain sensitivity. The reward an...

    Objectives: To compare physical activity (PA) and exercise dependence (ED) in 267 weight-loss maintainers (WLM) and 213 normal-weight (NW) controls. Methods: PA and ED assessed via accelerometery and the Exercise Dependence Questionnaire. Results: WLM had higher PA levels and ED scores than those of NW (P less than 0.0001). WLM status (P = 0.006)…

    The aim of the present study was to explore and illuminate the meaning of advanced nursing caring for men with alcohol dependency, as narrated by the men themselves. Ten male patients were interviewed in-depth and data were subjected to a phenomenological-hermeneutic analysis. Caring meant having the opportunity to rest in a safe haven together with professional caregivers, to struggle for liberation from dependency, and to expand the life-sphere by starting to accept oneself and broaden social participation. The findings illuminate various patterns of masculinity and point to the importance for caregivers to be open to challenging stereotypical gender assumptions.
