  1. Alcohol withdrawal syndrome--an auto-immune disease? A neuroimmunologic model for pathogenesis of alcohol withdrawal symptoms.

    PubMed

    Schubert, S

    1990-08-01

    A neuroimmunologic model of alcohol withdrawal symptoms is developed according to which these may be considered as an idiopathic auto-immune disease. During the alcohol abuse period of non-addicts, homeostasis may alter pathologically by gradual adaptation of the organism: auto-sensitisation develops and finally leads to the breakdown of auto-immune tolerance of the structural modifications set by alcohol withdrawal. The immunosystem regards the existing assimilation of alcohol as self, the withdrawal of alcohol as non-self. Alcohol withdrawal may be considered as an acknowledged physical stressor, and physical stressors as potential triggers of auto-immune diseases. Some so-called alcohol-induced diseases may originate in the pathogenic effects of preceding auto-immune responses to repeated alcohol withdrawals. Neuroimmunologic preconditions of potential auto-immune diseases exactly fit the alcohol withdrawal situation. Neuroimmunologic diseases themselves show close analogies respectively to alcohol withdrawal symptoms as well as to some alcohol-induced diseases. The myelin basis protein is assumed to be a potential auto-allergen. Finally withdrawal symptoms being the expression of physical dependence on alcohol, the model may highlight the very nature of physical dependence.

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

    Treatments for physical dependence and associated withdrawal symptoms following the abrupt discontinuation of prescription drugs (such as opioids and benzodiazepines), nicotine, alcohol, and cannabinoids are available, but there is still a need for new and more effective therapies. This review examines evidence supporting the potential use of pregabalin, an α2δ voltage-gated calcium channel subunit ligand, for the treatment of physical dependence and associated withdrawal symptoms. A literature search of the MEDLINE and Cochrane Library databases up to and including 11 December 2015 was conducted. The search term used was '(dependence OR withdrawal) AND pregabalin'. No other date limits were set and no language restrictions were applied. Works cited in identified articles were cross-referenced and personal archives of references also searched. Articles were included based on the expert opinions of the authors. There is limited evidence supporting the role of pregabalin for the treatment of physical dependence and accompanying withdrawal symptoms associated with opioids, benzodiazepines, nicotine, cannabinoids, and alcohol, although data from randomized controlled studies are sparse. However, the current evidence is promising and provides a platform for future studies, including appropriate randomized, placebo- and/or comparator-controlled studies, to further explore the efficacy and safety of pregabalin for the treatment of withdrawal symptoms. Given the potential for pregabalin misuse or abuse, particularly in individuals with a previous history of substance abuse, clinicians should exercise caution when using pregabalin in this patient population.

  5. Investigation of allyphenyline efficacy in the treatment of alcohol withdrawal symptoms.

    We have recently demonstrated that allyphenyline, behaving as α2C-adrenoceptor/serotonin 5-HT1A receptor agonist and α2A-adrenoceptor antagonist, in mice enhanced morphine analgesia, attenuated morphine withdrawal symptoms, showed significant antidepressant-like activity and was devoid of sedative side effects. Opioid and alcohol withdrawal shares several common neurobiological and molecular mechanisms. Therefore, in this study we expanded our analysis of the pharmacological properties of allyphenyline by investigating its ability to prevent the expression of somatic withdrawal signs, anxiety-like behavior and hyperlocomotion associated with chronic ethanol intoxication. Rats were subjected to induction of ethanol dependence via repeated daily intragastric ethanol (20%) administration for 4 consecutive days. Twelve hours after the last alcohol administration, somatic alcohol withdrawal signs were scored. Results revealed a significant expression of physical withdrawal signs that were not affected by intraperitoneal (i.p.) administration of allyphenyline at the doses of 0.05, 0.275 and 0.5 mg/kg. In contrast, allyphenyline (0.05 and 0.275 mg/kg i.p.) significantly reduced hyperanxiety-like behavior observed 6 days after alcohol intoxication as measured using the defensive burying test. Allyphenyline also reduced open field hyperlocomotor activity associated with alcohol withdrawal. Notably, the anxiolytic effect of the compound, as well as the already reported antidepressant action, was observed at very low doses, suggesting the involvement of its α2C-adrenoceptor/serotonin 5-HT1A receptor agonism. Therefore, the present investigation suggests that allyphenyline might represent an interesting pharmacological tool to investigate the potential of compounds exhibiting α2C-adrenoceptor/serotonin 5-HT1A receptor agonism and α2A-adrenoceptor antagonism in the treatment of hyperanxiety and hyperlocomotion occurring during alcohol withdrawal in dependent subjects.

    Improved treatment of alcohol dependence is a high priority, including defining subtypes that might respond differently. We evaluated a medication combination of intravenous flumazenil (FMZ) and oral gabapentin (GBP) in alcoholics who did and did not exhibit pretreatment alcohol withdrawal (AW) symptoms. Sixty alcohol-dependent individuals (44 with low AW and 16 with high AW) were randomized to receive FMZ (2 mg of incremental bolus for 20 minutes for 2 consecutive days) and GBP (up to 1200 mg nightly for 39 days) or their inactive placebos. Alcohol withdrawal was measured for the first 2 days, and drinking, sleep parameters, and adverse events were monitored during weekly evaluations, along with behavioral counseling sessions. Percent days abstinent (PDA) during treatment and time to first heavy drinking (TFHD) day were primary outcome variables. There was an interaction between the pretreatment AW status and the medication group on PDA (P = 0.0006) and TFHD (P = 0.06). Those in the high AW group had more PDA and more TFHD if treated with active medications, whereas those in the low AW group had more PDA and more TFHD if treated with placebo. This interaction remained for those totally abstinent (P = 0.03) and was confirmed by percent carbohydrate-deficient transferrin values. In addition, the pattern of response remained up to 8 weeks after treatment. In addition, in those with high AW, greater improvement in AW symptoms was observed in the active medication group compared with the placebo group. These results suggest a differential response to FMZ/GBP treatment, depending on pretreatment AW status that should be taken into account during future treatment trials.

    A 55-year-old man was admitted for a femur fracture; an alcohol fetor was noted on admission. The following day, the patient began to experience tremors and nervousness. Intravenous haloperidol was administered. Shortly afterwards, the patient experienced two generalized seizures and then began to experience delirium and uncontrollable agitation. The patient was diagnosed with alcohol withdrawal syndrome; high doses of intravenous midazolam were prescribed and infused. A few hours later, the patient presented signs of respiratory depression, requiring a transfer to the intensive care unit. After a review of the medical history, it was determined that the patient had been admitted on 3 previous occasions due to alcohol withdrawal and had progressed to delirium tremens after experiencing seizures. Can the risk of alcohol withdrawal syndrome and the need for prophylactic treatment be assessed on admission? Were appropriate monitoring and treatment measures employed? Would it have been possible to change his outcome?

    Gabapentin is an anticonvulsant agent, also effective in the treatment of mood disorders and anxiety disorders. Three cases of alcohol withdrawal treated with gabapentin are presented. All patients received gabapentin 400 mg tid for 3 days, 400 mg bid for 1 day, and finally 400 mg for 1 day. Withdrawal symptoms subsided and no adverse effects were observed. The possible effectiveness of gabapentin in the treatment of alcohol withdrawal warrants further investigation by systematic and well-designed studies.

    Symptoms of alcohol withdrawal syndrome may develop within 6–24 hours after the abrupt discontinuation or decrease of alcohol consumption. Symptoms can vary from autonomic hyperactivity and agitation to delirium tremens. The gold-standard treatment for alcohol withdrawal syndrome is represented by benzodiazepines. Among them, different agents (i.e., long-acting or short-acting) and different regimens (front-loading, fixed dose or symptom-triggered) may be chosen on the basis of patient characteristics. Severe withdrawal could require ICU admission and the use of barbiturates or propofol. Other drugs, such as alpha2-agonists (clonidine and dexmetedomidine) and beta-blockers can be used as adjunctive treatments to control neuroautonomic hyperactivity. Furthermore, neuroleptics can help control hallucinations. Finally, other medications for the treatment for alcohol withdrawal syndrome have been investigated with promising results. These include carbamazepine, valproate, sodium oxybate, baclofen, gabapentin, and topiramate. The usefulness of these agents will be discussed in the text. PMID:25666543

  11. Alcohol Withdrawal and Cerebellar Mitochondria.

    Jung, Marianna E

    2015-08-01

    Cerebellar disorders trigger the symptoms of movement problems, imbalance, incoordination, and frequent fall. Cerebellar disorders are shown in various CNS illnesses including a drinking disorder called alcoholism. Alcoholism is manifested as an inability to control drinking in spite of adverse consequences. Human and animal studies have shown that cerebellar symptoms persist even after complete abstinence from drinking. In particular, the abrupt termination (ethanol withdrawal) of long-term excessive ethanol consumption has shown to provoke a variety of neuronal and mitochondrial damage to the cerebellum. Upon ethanol withdrawal, excitatory neurotransmitter molecules such as glutamate are overly released in brain areas including cerebellum. This is particularly relevant to the cerebellar neuronal network as glutamate signals are projected to Purkinje neurons through granular cells that are the most populated neuronal type in CNS. This excitatory neuronal signal may be elevated by ethanol withdrawal stress, which promotes an increase in intracellular Ca(2+) level and a decrease in a Ca(2+)-binding protein, both of which result in the excessive entry of Ca(2+) to the mitochondria. Subsequently, mitochondria undergo a prolonged opening of mitochondrial permeability transition pore and the overproduction of harmful free radicals, impeding adenosine triphosphate (ATP)-generating function. This in turn provokes the leakage of mitochondrial molecule cytochrome c to the cytosol, which triggers a cascade of adverse cytosol reactions. Upstream to this pathway, cerebellum under the condition of ethanol withdrawal has shown aberrant gene modifications through altered DNA methylation, histone acetylation, or microRNA expression. Interplay between these events and molecules may result in functional damage to cerebellar mitochondria and consequent neuronal degeneration, thereby contributing to motoric deficit. Mitochondria-targeting research may help develop a powerful new

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

    Approximately 2% to 9% of patients seen in a family physician's office have alcohol dependence. These patients are at risk of developing alcohol withdrawal syndrome if they abruptly abstain from alcohol use. Alcohol withdrawal syndrome begins six to 24 hours after the last intake of alcohol, and the signs and symptoms include tremors, agitation, nausea, sweating, vomiting, hallucinations, insomnia, tachycardia, hypertension, delirium, and seizures. Treatment aims to minimize symptoms, prevent complications, and facilitate continued abstinence from alcohol. Patients with mild or moderate alcohol withdrawal syndrome can be treated as outpatients, which minimizes expense and allows for less interruption of work and family life. Patients with severe symptoms or who are at high risk of complications should receive inpatient treatment. In addition to supportive therapy, benzodiazepines, either in a fixed-dose or symptom-triggered schedule, are recommended. Medication should be given at the onset of symptoms and continued until symptoms subside. Other medications, including carbamazepine, oxcarbazepine, valproic acid, and gabapentin, have less abuse potential but do not prevent seizures. Typically, physicians should see these patients daily until symptoms subside. Although effective treatment is an initial step in recovery, long-term success depends on facilitating the patient's entry into ongoing treatment.

    Alcohol withdrawal is a common condition encountered in the hospital setting after abrupt discontinuation of alcohol in an alcohol-dependent individual. Patients may present with mild symptoms of tremulousness and agitation or more severe symptoms including withdrawal seizures and delirium tremens. Management revolves around early identification of at-risk individuals and symptom assessment using a validated tool such as the revised Clinical Institute Withdrawal Assessment for Alcohol score. Benzodiazepines remain the mainstay of treatment and can be administered using a front-loading, fixed-dose, or symptom-triggered approach. Long-acting benzodiazepines such as chlordiazepoxide or diazepam are commonly used and may provide a smoother withdrawal than shorter-acting benzodiazepines, but there are no data to support superiority of one benzodiazepine over another. Elderly patients or those with significant liver disease may have increased accumulation and decreased clearance of the long-acting benzodiazepines, and lorazepam or oxazepam may be preferred in these patients. Patients with symptoms refractory to high doses of benzodiazepines may require addition of a rescue medication such as phenobarbital, propofol or dexmedetomidine. Anticonvulsants (carbamazepine, valproate, gabapentin) may have a role in the management of mild to moderate withdrawal. Other medications such as β-antagonists or neuroleptics may offer additional benefit in select patients but should not be used a monotherapy.

    As an addictive drug, alcohol produces withdrawal symptoms if discontinued abruptly after chronic use. Clonidine (CLN), a partial α2 -adrenergic agonist, and mirtazapine (MRT), an antagonist of α2 -adrenoceptor, both clinically aid alcohol withdrawal. Considering different mechanisms of action of the two drugs, this study was designed to see how far these two mechanistically different drugs differ in their ability to decrease the severity of ethanol withdrawal syndrome. The effect of CLN and MRT on ethanol withdrawal-induced anxiety, depression and memory impairment was analysed using EPM, FST and PAR tests, respectively. Animals received distilled water, ethanol and/or either of the drugs (CLN and MRT) in different doses. Relapse to alcohol use was analysed by CPP test. Animals received ethanol as a conditioning drug and distilled water, CLN or MRT as test drug. CLN and MRT both alleviated anxiety in a dose-dependent manner. MRT (4 mg/kg) was more effective than CLN (0.1 mg/kg) in ameliorating the anxiogenic effect of alcohol withdrawal. However, CLN treatment increased depression. It significantly decreased swimming time and increased immobility time, whereas MRT treatment decreased immobility time and increased climbing and swimming time during abstinence. The effect was dose dependent for both drugs. The results of PAR test show that CLN treatment worsens working memory. Significant increase in SDE and TSZ and decrease in SDL were observed in CLN-treated animals. MRT treatment, on the other hand, improved working memory at both doses. Further, both CLN and MRT alleviated craving. A significant decrease in time spent in the ethanol-paired chamber was seen. MRT treatment at both doses showed better effect than CLN in preventing the development of preference in CPP test. These findings indicate a potential therapeutic use and better profile of mirtazapine over clonidine in improving memory, as well as in alleviating depression, anxiety and craving associated

    Symptoms of alcohol withdrawal syndrome (AWS) may develop within 6-24 h after the abrupt discontinuation or decrease of alcohol consumption. Symptoms can vary from autonomic hyperactivity and agitation to delirium tremens. The gold-standard treatment for AWS is with benzodiazepines (BZDs). Among the BZDs, different agents (i.e., long-acting or short-acting) and different regimens (front-loading, fixed-dose or symptom-triggered) may be chosen on the basis of patient characteristics. Severe withdrawal could require ICU admission and the use of barbiturates or propofol. Other drugs, such as α2-agonists (clonidine and dexmetedomidine) and β-blockers can be used as adjunctive treatments to control neuroautonomic hyperactivity. Furthermore, neuroleptic agents can help control hallucinations. Finally, other medications for the treatment for AWS have been investigated with promising results. These include carbamazepine, valproate, sodium oxybate, baclofen, gabapentin and topiramate. The usefulness of these agents are discussed.

    Methadone is a synthetic opioid that binds to the κ-opioid receptor with a low affinity. This study tested the hypotheses that the genetic polymorphisms in the κ-opioid receptor 1 (OPRK1) gene region are associated with methadone treatment responses in a Taiwan methadone maintenance treatment (MMT) cohort. Seventeen single nucleotide polymorphisms (SNPs) in OPRK1 were selected and genotyped on DNA of 366 MMT patients. Six SNPs from rs7843965 to rs1051660 (intron 2 to exon 2) were significantly associated with body weight (P < 0.007). A haplotype of 4 SNPs rs7832417-rs16918853-rs702764-rs7817710 (exon 4 to intron 3) was associated with bone or joint aches (P ≤ 0.004) and with the amount of alcohol use (standard drinks per day; global P < 0.0001). The haplotype rs10958350-rs7016778-rs12675595 was associated with gooseflesh skin (global P < 0.0001), yawning (global P = 0.0001), and restlessness (global P < 0.0001) withdrawal symptoms. The findings suggest that genetic polymorphisms in OPRK1 were associated with the body weight, alcohol use, and opioid withdrawal symptoms in MMT patients.

    We experienced a case showing various psychotic symptoms following cessation of alcohol consumption. The symptoms included depressive state, delusion, confusion, psychomotor excitement and delirium, all of which disappeared in about two months. At first, we regarded all the symptoms as alcoholic hallucinosis, by a clinical standpoint, in spite of no auditory hallucination in this case. However, taking the overall clinical course into consideration, withdrawal syndrome could have been affected by some factors. One of the possibilities is that delusion might have been induced by aripiprazole. There still may be some other unknown influential factors on withdrawal, which are indicated by previous papers.

    Four in-patients with moderate alcohol-withdrawal syndromes benefited from treatment with gabapentin administered in an add-on fashion to clomethiazole. In comparison with the amount of clomethiazole required as estimated using a specially developed score during previous detoxifications of these patients at our hospital, gabapentin (400 mg q.i.d.) clearly reduced the amount of clomethiazole needed now Gabapentin, an anticonvulsant with favorable pharmacokinetic properties and tolerability, and with no known risk of dependence, may therefore be a useful new drug in the treatment of alcohol withdrawal. We believe that the potential value of gabapentin in alcohol withdrawal deserves further controlled studies.

    The purpose of the present study was to observe the psychosocial characteristics of withdrawal from cigarette smoking in comparison with those from caffeine (CAF) and alcoholic (ALC) beverage withdrawal. Twenty-seven healthy volunteers at a medial level of dependence on both cigarettes (nicotine, NCT) and either CAF or ALC, as judged by the DSM-IV-TR criteria for substance dependence, participated in this study. The participants were required to abstain from smoking and either CAF or ALC for 7 days, each one after another, with a 7-day interval. The order of abstinence was counterbalanced among the participants. Psychosocial parameters, including a desire for substances, social activity function, well-being, withdrawal symptoms, and vital signs, were assessed during the withdrawal periods. The study protocol was approved by the Jikei University Review Board. The results indicated that there were no differences in the maximum level of desire for a substance and the influence on social activity function between NCT and other substances during the withdrawal periods. As for withdrawal symptoms, NCT caused a more intensive degree of irritability than CAF or ALC, and a more intensive degree of difficulty concentrating and restlessness than did withdrawal from ALC. However, the subjective well-being questionnaire indicated no differences in these symptoms between NCT and other substances. The present results suggest that there are no significant differences in psychosocial manifestations regarding the difficulty in abstaining from NCT, CAF, and ALC.

    The present study represents an open-label clinical trial comparing treatment with a benzodiazepine (lorazepam) to divalproex in 11 inpatients with uncomplicated alcohol withdrawal syndrome. The trial used the Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) scale. There were no significant differences in demographics or substance use parameters between the divalproex group (n = 6) or the lorazepam group (n = 5). A significant Group x CIWA-Ar score interaction [F(8,72) = 2.57, p < or = .01] was confirmed and further substantiated by a quadratic trend component for the interaction [F(1,9) = 24.9, p < or = .001].

    Gabapentin was compared with phenobarbital for the treatment of alcohol withdrawal in a randomized, open-label, controlled trial in 27 inpatients. There were no significant differences in the proportion of treatment completers between treatment groups or the proportion of patients in each group requiring rescue medication for breakthrough signs and symptoms of alcohol withdrawal. There were no significant treatment differences in withdrawal symptoms or psychological distress, nor were there serious adverse events. These findings suggest that gabapentin may be as effective as phenobarbital in the treatment of alcohol withdrawal. Given gabapentin's favorable pharmacokinetic profile, further study of its effectiveness in treating alcohol withdrawal is warranted.

    2016-01-01

    Chronic intermittent alcohol vapor exposure leads to increased dynorphin (DYN) A-like peptide expression and heightened kappa-opioid receptor (KOR) signaling in the central nucleus of the amygdala (CeA) and these neuroadaptive responses differentiate alcohol-dependent from non-dependent phenotypes. Important for therapeutic development efforts is understanding the nature of the stimulus that drives dependence-like phenotypes such as escalated alcohol self-administration. Accordingly, the present study examined the impact of intra-CeA KOR antagonism on escalated operant alcohol self-administration and physiological withdrawal symptoms during acute withdrawal and protracted abstinence in rats previously exposed to chronic intermittent alcohol vapor. Following operant training, rats were implanted with intra-CeA guide cannula and exposed to long-term intermittent alcohol vapor exposure that resulted in escalated alcohol self-administration and elevated physiological withdrawal signs during acute withdrawal. Animals received intra-CeA infusions of the KOR antagonist nor-binaltorphimine (nor-BNI; 0, 2, 4, or 6 μg) prior to operant alcohol self-administration sessions and physiological withdrawal assessment during acute withdrawal and protracted abstinence. The results indicated that site-specific KOR antagonism in the CeA ameliorated escalated alcohol self-administration during both acute withdrawal and protracted abstinence test sessions, whereas KOR antagonism had no effect on physiological withdrawal scores at either time point. These results dissociate escalated alcohol self-administration from physiological withdrawal symptoms in relation to KOR signaling in the CeA and help clarify the nature of the stimulus that drives escalated alcohol self-administration during acute withdrawal and protracted abstinence.

    Elevations of serum homocysteine levels are a consistent finding in alcohol addiction. Serum S100B levels are altered in different neuropsychiatric disorders but not well investigated in alcohol withdrawal syndromes. Because of the close connection of S100B to ACTH and glutamate secretion that both are involved in neurodegeneration and symptoms of alcoholism the relationship of S100B and homocysteine to acute withdrawal variables has been examined. A total of 22 male and 9 female inpatients (mean age 46.9 ± 9.7 years) with an ICD-10 diagnosis of alcohol addiction without relevant affective comorbidity were examined on admission and after 24, 48, and 120 h during withdrawal. S100B and homocysteine levels in serum were collected, and severity of withdrawal symptoms (AWS-scale), applied withdrawal medication, initial serum ethanol levels and duration of addiction were recorded. Serum S100B and homocysteine levels declined significantly (P < .05) over time. Both levels declined with withdrawal syndrome severity. Females showed a trend to a more intense decline in serum S100B levels compared to males at day 5 (P = .06). Homocysteine levels displayed a negative relationship to applied amount of clomethiazole (P < .05) and correlated with age of onset of addiction. No withdrawal seizures were recorded during the trial. As it is known for homocysteine, S100B revealed to decline rapidly over withdrawal treatment in alcoholism. This effect is more pronounced in female patients. S100B could be of relevance in the neurobiology of alcohol withdrawal syndromes. It may be indirectly related to the level of stress level or glutamatergic activity during alcohol withdrawal.

    Central pontine myelinolysis (CPM) and extrapontine myelinolysis (EPM) are osmotic demyelination syndrome. A 45-year-old man with a history of alcoholism visited the ER with dysarthria and dysphagia for 2 days. These symptoms occurred 3 days after he had stopped drinking alcohol. The neurological symptoms progressed to anarthria, pseudobulbar palsy and gait disturbance. During admission, the electrolyte studies were within the normal range. Diffusion-weighted images revealed high signal intensities in the pons, thalamus and basal ganglia. Apparent diffusion coefficient image showed low signal intensities in the pontine lesion, but isosignal intensities in the extrapontine lesion. The symptoms gradually improved after 1 month with only conservative treatment. The 1 month-follow-up MRI showed significant reduction of the previous extrapontine lesions. These findings suggest that cytotoxic edema is central to the pathogenesis of CPM, but vasogenic edema plays an important role in the pathogenesis of EPM occurring during alcohol withdrawal.

  12. Acute coronary ischemia during alcohol withdrawal: a case report

    PubMed Central

    2011-01-01

    Introduction The potential of alcohol withdrawal to cause acute coronary events is an area that needs the urgent attention of clinicians and researchers. Case presentation We report the case of a 52-year-old heavy-alcohol-using Sri Lankan man who developed electocardiogram changes suggestive of an acute coronary event during alcohol withdrawal. Despite the patient being asymptomatic, subsequent echocardiogram showed evidence of ischemic myocardial dysfunction. We review the literature on precipitation of myocardial ischemia during alcohol withdrawal and propose possible mechanisms. Conclusions Alcohol withdrawal is a commonly observed phenomenon in hospitals. However, the number of cases reported in the literature of acute coronary events occurring during withdrawal is few. Many cases of acute ischemia or sudden cardiac deaths may be attributed to other well known complications of delirium tremens. This is an area needing the urgent attention of clinicians and epidemiologists. PMID:21838872

  13. Sodium oxybate: a review of its use in alcohol withdrawal syndrome and in the maintenance of abstinence in alcohol dependence.

    PubMed

    Keating, Gillian M

    2014-01-01

    A liquid formulation of sodium oxybate (Alcover(®)), the sodium salt of γ-hydroxybutyric acid (GHB), is approved in Italy and Austria for use in alcohol withdrawal syndrome and for the maintenance of abstinence in alcohol dependence. This article reviews the efficacy and tolerability of sodium oxybate in alcohol withdrawal syndrome and in the maintenance of abstinence in alcohol dependence, as well as summarizing its pharmacological properties. Results of randomized controlled trials indicate that sodium oxybate was at least as effective as diazepam and clomethiazole in patients with alcohol withdrawal syndrome, rapidly alleviating symptoms, and was at least as effective as naltrexone or disulfiram in the maintenance of abstinence in alcohol-dependent patients. Sodium oxybate was generally well tolerated. The risk of sodium oxybate abuse is generally low when it is administered to alcohol-dependent patients at its approved dosage, under the supervision of a designated family member and with continuous strict medical surveillance. However, certain patient groups, such as patients with alcohol dependence and borderline personality disorder or who are in remission from heroin or cocaine addiction, may not be suitable candidates for sodium oxybate therapy because of an increased risk of abuse. In conclusion, sodium oxybate is a useful option for the treatment of alcohol withdrawal syndrome and for the maintenance of abstinence in alcohol dependence.

  14. K(Ca)2 channels: novel therapeutic targets for treating alcohol withdrawal and escalation of alcohol consumption.

    2012-06-01

    Small-conductance, calcium-activated potassium (K(Ca)2) channels influence neuronal firing properties, intrinsic excitability, and NMDA receptor-dependent synaptic responses and plasticity. In this mini-review, we discuss new evidence that chronic alcohol-associated plasticity critically involves K(Ca)2 channels in hippocampus, ventral tegmental area, and nucleus accumbens. K(Ca)2 channel activity can modulate the magnitude of excitation of midbrain dopamine neurons induced by acute alcohol exposure. Emerging evidence indicates that K(Ca)2 channels regulate neuroadaptations to chronic alcohol that contribute to withdrawal hyperexcitability and escalation of voluntary alcohol consumption. Restoring K(Ca)2 channel activity can attenuate the severity of the alcohol withdrawal syndrome in vivo and withdrawal-associated neurotoxicity in vitro. Pharmacological modulation of K(Ca)2 channels can bi-directionally influence drinking behavior in rat and mouse models of voluntary alcohol consumption. Collectively, these studies using various rodent models have clearly indicated a central role for K(Ca)2 channels in the neuroplasticity of chronic alcohol exposure. In addition, accumulating evidence suggests that K(Ca)2 channels are a novel therapeutic target to alleviate the symptoms of alcohol withdrawal and reduce high amounts of alcohol drinking.

  15. Cocaine withdrawal symptoms identify "Type B" cocaine-dependent patients.

    Recent studies of substance dependence typologies briefly show that multivariate systems originally developed for identifying subtypes of alcoholics, such as Babor's Type A and B system, may also be valid in abusers of other substances, such as cocaine. Type B patients are characterized by an earlier onset of addiction and more severe symptoms of their addiction, psychopathology, and impulsivity. The Type B classification has also been associated with deficits in serotonergic function. We have found that patients who exhibit more severe cocaine withdrawal symptoms, as measured by scores on the Cocaine Selective Severity Assessment (CSSA), have poor treatment outcome and share many characteristics with "Type B" patients. In this paper, we review baseline characteristics of cocaine-dependent patients from several recently completed outpatient cocaine dependence treatment trials to assess the association of cocaine withdrawal symptom severity and the Type B profile. Identifying subtypes of cocaine-dependent patients may improve our ability to treat cocaine dependence by targeting treatments for specific subtypes of patients. We examined the ability of the CSSA scores to capture Type B characteristics in cocaine dependence by analyzing a series of cocaine medication trials that included 255 cocaine-dependent subjects. High CSSA scores at baseline were associated with a history of violent behavior, a family history of substance abuse, antisocial personality disorder, higher addiction severity, and co-morbid psychiatric diseases. Patients with high CSSA scores are also more likely to meet criteria for Type B (Type II) cocaine dependence. Identifying Type B cocaine-dependent patients may help to develop targeted psychosocial or pharmacological treatments for these difficult-to-treat patients.

  16. Withdrawal symptoms in internet gaming disorder: A systematic review.

    2016-02-01

    Internet gaming disorder (IGD) is currently positioned in the appendix of the DSM-5 as a condition requiring further study. The aim of this review was to examine the state of current knowledge of gaming withdrawal symptomatology, given the importance of withdrawal in positioning the disorder as a behavioral addiction. A total of 34 studies, including 10 qualitative studies, 17 research reports on psychometric instruments, and 7 treatment studies, were evaluated. The results indicated that the available evidence on Internet gaming withdrawal is very underdeveloped. Internet gaming withdrawal is most consistently referred to as 'irritability' and 'restlessness' following cessation of the activity. There exists a concerning paucity of qualitative studies that provide detailed clinical descriptions of symptoms arising from cessation of internet gaming. This has arguably compromised efforts to quantify withdrawal symptoms in empirical studies of gaming populations. Treatment studies have not reported on the natural course of withdrawal and/or withdrawal symptom trajectory following intervention. It is concluded that many more qualitative clinical studies are needed, and should be prioritised, to develop our understanding of gaming withdrawal. This should improve clinical descriptions of problematic internet gaming and in turn improve the quantification of IGD withdrawal and thus treatments for harmful internet gaming.

    This study examined the relationship between cocaine withdrawal and lifetime history of depression (major depression, dysthymia). Participants with a history of regular cocaine use (n = 146) were administered the Structured Clinical Interview for the DSM-IV (SCID) and were asked to recall whether they experienced any of the six DSM-IV cocaine withdrawal symptoms. Results of bivariate analyses demonstrated that those meeting criteria for the cocaine withdrawal syndrome (dysphoria plus two or more other symptoms), in comparison to those who did not, were significantly (P<.001) more likely to have a lifetime history of depression. Lifetime history of depression was also more common in those individuals reporting the withdrawal symptoms of "dysphoria" (P<.001), "insomnia/hypersomnia" (P<.05), "vivid unpleasant dreams" (P<.01), and "psychomotor agitation/retardation" (P<.01). These relationships remained significant after controlling for demographics, severity of addiction, and the presence of opiate, alcohol and cannabis dependence or abuse. The withdrawal symptoms of "fatigue" and "increased appetite" were not associated with mood history. Results suggest that lifetime history of depression is strongly related to whether or not a cocaine abuser self-reports withdrawal symptoms. Several competing hypotheses regarding the nature of this relationship are discussed.

    Introduction Some anticonvulsants ameliorate signs and symptoms of alcohol withdrawal, but have an unacceptable side effect burden. Among the advantages of using anticonvulsant agents in this capacity is their purported lack of interaction with alcohol that could increase psychomotor deficits, increase cognitive impairment, or increase intoxication. The aim of the current study was to evaluate alcohol use and symptom reduction of gabapentin as compared to lorazepam in the treatment of alcohol withdrawal in a double-blinded randomized clinical trial. Methods One hundred individuals seeking outpatient treatment of alcohol withdrawal with Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) ratings ≥10 were randomized to double-blind treatment with two doses of gabapentin (900 mg tapering to 600 mg or 1200 tapering to 800 mg) or lorazepam (6 mg tapering to 4 mg) for four days. Severity of alcohol withdrawal was measured by the CIWA-Ar on days 1-4 of treatment and on days 5, 7 and 12 post-treatment and alcohol use monitored by verbal report and breath alcohol levels Results CIWA-Ar scores decreased over time in all groups; high-dose gabapentin was statistically superior but clinically similar to lorazepam (p=0.009). During treatment, lorazepam-treated participants had higher probabilities of drinking on the first day of dose decrease (day 2) and the second day off medication (day 6) as compared to gabapentin-treated participants (p=.0002). Post-treatment, gabapentin-treated participants had less probability of drinking during the follow-up post-treatment period (probability=.2 for 900 mg and probability=.3 for 1200mg) compared to the lorazepam-treated participants (probability=.55). The gabapentin groups also had less craving, anxiety, and sedation compared to lorazepam. Conclusions Gabapentin was well tolerated and effectively diminished the symptoms of alcohol withdrawal in our population especially at the higher target dose (1200mg) used in this

    This paper evaluates the relation between Alcohol Withdrawal Syndrome tremors in the left and right hands of patients. By analyzing 122 recordings from 61 patients in emergency departments, we found a weak relationship between the left and right hand tremor frequencies (correlation coefficient of 0.63). We found a much stronger relationship between the expert physician tremor ratings (on CIWA-Ar 0-7 scale) of the two hands, with a correlation coefficient of 0.923. Next, using a smartphone to collect the tremor data and using a previously developed model for obtaining estimated tremor ratings, we also found a strong correlation (correlation coefficient of 0.852) between the estimates of each hand. Finally, we evaluated different methods of combining the data from the two hands for obtaining a single tremor rating estimate, and found that simply averaging the tremor ratings of the two hands results in the lowest tremor estimate error (an RMSE of 0.977). Looking at the frequency dependence of this error, we found that higher frequency tremors had a much lower estimation error (an RMSE of 1.102 for tremors with frequencies in the 3-6Hz range as compared to 0.625 for tremors with frequencies in the 7-10Hz range).

  20. Acute withdrawal, protracted abstinence and negative affect in alcoholism: Are they linked?

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

    Background The current study examined tobacco withdrawal symptoms and withdrawal-related discomfort and relapse in smokers with and without current mood disorders, anxiety disorders, alcohol use disorders (AUD), and substance use disorders (SUD). Methods The subsample of current daily smokers (n=8,213) from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, Wave 1, 2001–2002, full sample n=43,093) were included in these analyses. Cross-sectional data compared smokers with and without current psychiatric disorders on withdrawal symptoms using logistic regression models. The effects of having a co-morbid psychiatric disorder and AUD/SUD compared to a psychiatric disorder alone on nicotine withdrawal were also examined. Results Participants with a current mood disorder, anxiety disorder, AUD, or SUD were more likely to report withdrawal symptoms and reported more withdrawal symptoms than those without current disorders. Having a current mood disorder, anxiety disorder, and SUD was also associated with increased likelihood of withdrawal-related discomfort and relapse. There were no significant interactions between psychiatric disorders and AUDs/SUDs on withdrawal symptoms or behavior. Conclusions Participants with a current Axis I disorder were more likely to experience tobacco withdrawal symptoms and withdrawal-related discomfort and relapse. Having a co-morbid psychiatric disorder and AUD/SUD did not synergistically increase the experience of withdrawal-related symptoms or relapse. It is important to identify Axis I disorders in smokers and provide these smokers with more intensive and/or longer treatments to help them cope with withdrawal symptoms and prevent relapse.

    Chronic alcohol abuse depresses the nervous system and, upon cessation, rebound hyperexcitability can result in withdrawal seizure. Withdrawal symptoms, including seizures, may drive individuals to relapse, thus representing a significant barrier to recovery. Our lab previously identified an upregulation of the thalamic T-type calcium (T channel) isoform CaV3.2 as a potential contributor to the generation and propagation of seizures in a model of withdrawal. In the present study, we examined whether ethosuximide (ETX), a T-channel antagonist, could decrease the severity of ethanol withdrawal seizures by evaluating electrographical and behavioral correlates of seizure activity. DBA/2J mice were exposed to an intermittent ethanol exposure paradigm. Mice were treated with saline or ETX in each withdrawal period, and cortical EEG activity was recorded to determine seizure severity. We observed a progression in seizure activity with each successive withdrawal period. Treatment with ETX reduced ethanol withdrawal-induced spike and wave discharges (SWDs), in terms of absolute number, duration of events, and contribution to EEG power reduction in the 6–10 Hz frequency range. We also evaluated the effects of ETX on handling-induced convulsions. Overall, we observed a decrease in handling-induced convulsion severity in mice treated with ETX. Our findings suggest that ETX may be a useful pharmacological agent for studies of alcohol withdrawal and treatment of resulting seizures. PMID:24933286

    2015-01-01

    Withdrawal-based theories of addiction hypothesize that motivation to reinstate drug use following acute abstinence is mediated by withdrawal symptoms. Experimental tests of this hypothesis in the tobacco literature are scant and may be subject to methodological limitations. This study utilized a robust within-subject laboratory experimental design to investigate the extent to which composite tobacco withdrawal symptomatology level and three unique withdrawal components (i.e., low positive affect, negative affect, and urge to smoke) mediated the effect of smoking abstinence on motivation to reinstate smoking. Smokers (10≥cig/day; N=286) attended two counterbalanced sessions at which abstinence duration was differentially manipulated (1-hour vs. 17-hours). At both sessions, participants reported current withdrawal symptoms and subsequently completed a task in which they were monetarily rewarded proportional to the length of time they delayed initiating smoking, with shorter latency reflecting stronger motivation to reinstate smoking. Abstinence reduced latency to smoking initiation and positive affect and increased composite withdrawal symptom level, urge, and negative affect. Abstinence-induced reductions in latency to initiating smoking were mediated by each withdrawal component, with stronger effects operating through urge. Combined analyses suggested that urge, negative affect, and low positive affect operate through empirically-unique mediational pathways. Secondary analyses suggested similar effects on smoking quantity, few differences among specific urge and affect subtypes, and that dependence amplifies some abstinence effects. This study provides the first experimental evidence that within-person variation in abstinence impacts motivation to reinstate drug use through withdrawal. Urge, negative affect, and low positive affect may reflect unique withdrawal-mediated mechanisms underlying tobacco addiction. PMID:25961814

    An antiparkinson drug (APK) withdrawal study was carried out in 34 schizophrenic outpatients on maintenance neuroleptics. Sixty-five percent of patients were without major complaints after 2 weeks of APK discontinuation, while 35% reported adverse effects including extrapyramidal, autonomic, and behavioral symptoms. Male patients and those on higher diethazine doses before withdrawal reported more complaints. Ratings showed significant increases of parkinsonism, as well as dyskinesia following APK withdrawal. No clinical evidence was obtained in support of the notion of cholinergic hypersensitivity in patients showing "tremors" at baseline.

    Negative affect promotes dysregulated alcohol consumption in non-dependent and alcohol-dependent animals, and cues associated with negative affective states induce withdrawal-like symptoms in rats. This study was designed to test the hypotheses that: (1) the kappa-opioid receptor (KOR) system mediates phenotypes related to alcohol withdrawal and withdrawal-like negative affective states and (2) cues associated with negative affective states would result in dysregulated alcohol consumption when subsequently presented alone. To accomplish these goals, intracerebroventricular infusion of the KOR antagonist nor-binaltorphimine (nor-BNI) was assessed for the ability to attenuate the increase in 22-kHz ultrasonic vocalizations (USVs) associated with alcohol withdrawal and KOR activation in adult male wistar rats. Furthermore, cues associated with a KOR agonist-induced negative affective state were assessed for the ability to dysregulate alcohol consumption and the efficacy of intracerebroventricular KOR antagonism to reduce such dysregulation was evaluated. KOR antagonism blocked the increased number of 22-kHz USVs observed during acute alcohol withdrawal and a KOR agonist (U50,488) resulted in a nor-BNI reversible increase in 22-kHz USVs (mimicking an alcohol-dependent state). Additionally, cues associated with negative affective states resulted in escalated alcohol self-administration, an effect that was nor-BNI sensitive. Taken together, this study implicates negative affective states induced by both alcohol withdrawal and conditioned stimuli as being produced, in part, by activity of the DYN/KOR system.

     A 70-year-old woman, residing in a nursing home, was admitted to our hospital because of cerebral hemorrhage. She had excessive sweating, a temperature above 37°C, and intermittent muscle spasm such as myoclonus, since the time of admission. We suspected that these symptoms were related to side effects caused by the milnacipran she was taking for depression, prior to hospitalization. After we discontinued milnacipran, the patient began exhibiting withdrawal symptoms such as excitement and insomnia. When we substituted milnacipran with mianserin, the withdrawal symptoms diminished and the excessive sweating and involuntary movement disappeared. Serotonin-norepinephrine reuptake inhibitor (SNRI) and selective serotonin reuptake inhibitor (SSRI) have been widely utilized in the clinic to treat depression; serious side effects such as serotonin syndrome and withdrawal syndrome associated with their discontinuation, have been reported. However, it is unlikely that serotonin syndrome and withdrawal syndrome due to a precedent use of milnacipran would have been reported. This case was suspected to be related to serotonin syndrome and withdrawal syndrome from the course of treatment. This case provides valuable information for addressing new similar cases caused by milnacipran.

    1996-01-01

    Craving is an integral element in the understanding of alcohol dependence. Recent human and animal research implicates the serotonergic and dopaminergic systems in the mediation of excessive alcohol consumption. In this study, a cue-based approach was used to qualify and quantify craving occurring during acute withdrawal from alcohol. Fifty alcoholics were given either placebo, bromocriptine or fluoxetine in a randomised double-blind fashion and craving was sequentially measured over the next 15 days. Both fluoxetine and bromocriptine significantly attenuated total craving scores without similarly affecting withdrawal symptoms. The results suggest the importance of neurotransmitters in mediating craving. The significance of these data in the light of various behavioural and neurochemical models have been discussed.

    Chronic alcohol intoxication is accompanied by metabolic abnormalities. Evolution during the early withdrawal period has been poorly investigated. The aim of this study was to determine the evolution of metabolic parameters during alcohol withdrawal. Patients and Methods. Thirty-three patients admitted in our department for alcohol withdrawal were prospectively included. Results. Baseline hypophosphatemia was found in 24% of cases. FEPO4 was reduced from 14.2 ± 9% at baseline to 7.3 ± 4.2% at day 3 (P < 0.01). FEPO4 inversely correlated with albuminemia (rs = −0.41, P = 0.01). CPK level was 124 ± 104 IU/L in men and 145 ± 85 IU/L in women (nl < 308 and <192 IU/L, resp.), 7% and 28% of patients having a CPK level >nl, respectively. No correlation was found between the sodium and CPK levels (P = 0.75) nor between the CPK level and the amount of alcohol ingested (rs = 0.084, P = 0.097). Baseline urate level was elevated and returned to normal after three days. Baseline magnesium concentration was normal and stable over time. Conclusion. Chronic alcohol intoxication was accompanied by phosphaturia, rapidly reversible after alcohol withdrawal and inversely correlated with albuminemia, slight hyponatremia, low levels of 25 hydroxy vitamin D, elevated CPK level in about 30% of women, and hyperuricemia with rapid normalization.

    Objectives: Benzodiazepines (BZDs) are the first-line drugs in alcohol-withdrawal syndrome (AWS). Baclofen, a gamma-aminobutyric acidB (GABAB) agonist, controls withdrawal symptoms without causing significant adverse effects. The objective of this study was to compare the cost-effectiveness of baclofen and chlordiazepoxide in the management of uncomplicated AWS. Materials and Methods: This was a randomized, open label, standard controlled, parallel group study of cost-effectiveness analysis (CEA) of baclofen and chlordiazepoxide in 60 participants with uncomplicated AWS. Clinical efficacy was measured by the Clinical Institute Withdrawal Assessment for alcohol (CIWA-Ar) scores. Lorazepam was used as supplement medication if withdrawal symptoms could not be controlled effectively by the study drugs alone. Both direct and indirect medical costs were considered and the CEA was analyzed in both patient's perspective and third-party perspective. Results: The average cost-effectiveness ratio (ACER) in patient's perspective of baclofen and chlordiazepoxide was Rs. 5,308.61 and Rs. 2,951.95 per symptom-free day, respectively. The ACER in third-party perspective of baclofen and chlordiazepoxide was Rs. 895.01 and Rs. 476.29 per symptom-free day, respectively. Participants on chlordiazepoxide had more number of symptom-free days when compared with the baclofen group on analysis by Mann-Whitney test (U = 253.50, P = 0.03). Conclusion: Both study drugs provided relief of withdrawal symptoms. Chlordiazepoxide was more cost-effective than baclofen. Baclofen was relatively less effective and more expensive than chlordiazepoxide. PMID:25097273

    Demyelination is a hallmark of central pontine myelinolysis (CPM). Neuropsychiatric manifestations of this condition include weakness, quadriplegia, pseudobulbar palsy, mood changes, psychosis, and cognitive disturbances. These psychiatric symptoms are also associated with schizophrenia and alcohol withdrawal. Thus, it is clinically relevant to differentiate between CPM, schizophrenia, and alcohol withdrawal as the treatment and prognostic outcomes for each diagnosis are distinct. We present a series of events that led to a misdiagnosis of a patient admitted to the medical emergency center presenting with confusion, psychomotor agitation, and delirium who was first diagnosed with schizophrenia and alcohol withdrawal by emergency medical physicians and later discovered by the psychiatric consult team to have CPM. With a thorough psychiatric evaluation, a review of the laboratory results first showing mild hyponatremia (127 mmol/L), subsequent hypernatremia (154 mmol/L), and magnetic resonance brain imaging, psychiatrists concluded that CPM was the primary diagnosis underlying the observed neuropsychopathology. This patient has mild impairments in mood, cognition, and motor skills that remain 12 months after her emergency-center admission. This case report reminds emergency clinicians that abnormal sodium metabolism can have long-term and devastating psychopathological and neurological consequences. Differentiating between CPM, schizophrenia, and alcohol withdrawal using neuroimaging techniques and preventing the risks for CPM using slow sodium correction are paramount. PMID:22347796

    Heterogeneity in the clinical symptoms of alcohol abuse was examined in 243 men and 305 women from families of hospitalized alcoholics, who had demonstrated different patterns of inheritance of susceptibility to alcoholism. Discriminant analysis was utilized to identify nine alcoholic symptoms that distinguished male relatives of alcoholic men from those of alcoholic women. Inability to abstain from alcohol, fighting and reckless driving while intoxicated, and alcohol treatment other than Alcoholics Anonymous were more prevalent in families of male probands. Male relatives of female probands experienced later onset of loss of control over drinking associated with benders, and cirrhosis and feelings of guilt. Female relatives of alcoholic men and women showed a marked predominance of the latter (Type 1) features, whereas male relatives had different clinical features, depending on the associated mode of inheritance.

  15. Central Pontine Myelinolysis Induced by Alcohol Withdrawal: A Case Report

    PubMed Central

    2017-01-01

    Central pontine myelinolysis (CPM) is a demyelinating disorder characterized by the loss of myelin in the center of the basis pons, and is mainly caused by the rapid correction of hyponatremia. We report the case of a young woman who presented with gait disturbance and alcohol withdrawal, and who was eventually diagnosed with CPM. Generally, the cause and pathogenesis of CPM in chronic alcoholics remain unclear. In this cases, the CPM may be unrelated to hyponatremia or its correction. However, it is possible that the osmotic pressure changes due to refeeding syndrome after alcohol withdrawal was the likely cause in this case. This case illustrates the need for avoiding hasty, and possibly incomplete diagnoses, and performing more intensive test procedures to ensure a correct diagnosis. PMID:28289647

    This is a report of a 6-year follow-up of a male patient's semen parameters during heavy chronic alcohol intoxication and after withdrawal. A slowly progressive negative impact of alcohol could be observed: isolated moderate teratozoospermia was firstly noted followed by oligoasthenoteratospermia. Then a severe worsening resulted in cryptozoospermia and ultimately in azoospermia. At this moment, the histological analysis of a testicular biopsy revealed a maturation arrest of the germinal cells at the pachytene stage with no mature sperm cells. Alcohol withdrawal was then obtained, allowing a very fast and drastic improvement of semen characteristics; strictly normal semen parameters were observed after no more than 3 months. Taking into consideration these data, patients should be questioned about their alcohol intake before assisted reproductive technology and should be informed about this adverse effect. Moreover, this case report emphasizes how quickly benefits can be obtained after withdrawal, even in the case of heavy chronic alcohol intake.

    Background Alcohol use disorders (AUDs) frequently co-occur with and exacerbate schizophrenia, yet the specific relationships between schizophrenia symptoms and alcohol use remain unclear. Methods PANSS scores were correlated with measures of alcohol and other substance use in patients with schizophrenia-spectrum disorders and AUDs entering a trial of monitored naltrexone treatment. Data were analyzed from the first 80 participants; 55% had schizophrenia and 45% had schizoaffective disorder. All had AUDs; 95% had alcohol dependence and 5% alcohol abuse; 34% also had cannabis abuse/dependence and 31% cocaine abuse/dependence. Results PANSS Negative scores were inversely correlated with Addiction Severity Index alcohol composite score, alcohol craving, quality of alcohol “high” (euphoria), and with frequency of cannabis use. An exploratory analysis indicated that the negative symptoms that may most strongly correlate with less alcohol use, craving or euphoria were passive/apathetic social withdrawal, blunted affect, difficulty in abstract thinking, and stereotyped thinking. Higher PANSS Composite scores, indicating the predominance of positive over negative PANSS symptoms, correlated with more alcohol craving and cannabis use. Higher PANSS General scores were associated with more alcohol craving. Conclusions These findings extend previous reports of the association of negative schizophrenia symptoms with less alcohol and substance use to patients with AUDs and indicate that this relationship also includes less alcohol craving and less alcohol euphoria. The findings may also provide some initial evidence that specific negative symptoms may be key to these relationships. PMID:18701256

    Stress (Takotsubo) cardiomyopathy is a form of reversible left ventricular dysfunction with a heightened risk of ventricular arrhythmia thought to be caused by high circulating catecholamines. We report a case of stress cardiomyopathy that developed during severe alcohol withdrawal successfully treated with dexmedetomidine. The case involves a 53-year-old man with a significant history of alcohol abuse who presented to a teaching hospital with new-onset seizures. His symptoms of acute alcohol withdrawal were initially treated with benzodiazepines, but the patient later developed hypotension, and stress cardiomyopathy was suspected based on ECG and echocardiographic findings. Adjunctive treatment with the alpha-2-adrenergic agonist, dexmedetomidine, was initiated to curtail excessive sympathetic outflow of the withdrawal syndrome, thereby targeting the presumed pathophysiology of the cardiomyopathy. Significant clinical improvement was observed within one day of initiation of dexmedetomidine. These findings are consistent with other reports suggesting that sympathetic dysregulation during alcohol withdrawal produces ideal pathobiology for stress cardiomyopathy and leads to ventricular arrhythmogenicity. Stress cardiomyopathy should be recognized as a complication of alcohol withdrawal that significantly increases cardiac-related mortality. By helping to correct autonomic dysregulation of the withdrawal syndrome, dexmedetomidine may be useful in the treatment of stress-induced cardiomyopathy. PMID:27006838

    As the inhibitory neurotransmitter gamma aminobutyric acid (GABA) modulates ethanol consumption, alcohol withdrawal symptoms and seizure generation by interacting with the GABAB receptor, the genes encoding for the GABAB receptor can be considered as candidate genes for alcoholism and alcohol withdrawal seizures (AWS). As the polymorphism GABABR1 T1974C[rs29230] of the GABAB receptor gene had been associated with alcoholism and EEG abnormalities in prior studies, the present examination investigated if the polymorphism is associated with the diagnosis of alcoholism or AWS. After genotyping the allele and genotype frequencies of a group of alcoholics with a history of AWS (n = 69) were compared with the results of a group of alcoholics with only mild withdrawal symptoms (n = 97). Additionally a group of healthy controls (n = 101) was compared with individuals with the diagnosis of alcoholism (n = 220). As no significant differences were found between the compared groups, this study gave no further evidence for GABABR1 T1974C[rs29230] as a candidate for alcoholism or AWS.

  2. Clinical Evolution of Central Pontine Myelinolysis in a Patient with Alcohol Withdrawal: A Blurred Clinical Horizon

    2016-01-01

    Central pontine myelinolysis (CPM), a potentially fatal and debilitating neurological condition, was first described in 1959 in a study on alcoholic and malnourished patients. It is a condition most frequently related to rapid correction of hyponatremia. Chronic alcoholism associated CPM tends to be benign with a favorable prognosis compared to CPM secondary to rapid correction of hyponatremia. We describe a normonatremic, alcoholic patient who presented with CPM after a rapid rise in his sodium levels. Our case illustrates the fact that CPM can manifest even in patients who are normonatremic at baseline. Rapid rises in sodium levels should be promptly reversed before clinical symptoms manifest in patient with risk factors for CPM irrespective of their baseline sodium levels. Furthermore, clinical evolution of CPM can be difficult to discern from the natural course of alcohol withdrawal delirium, requiring astuteness and maintenance of a high degree of clinical suspicion on the part of the physician.

    Discontinuation of clozapine and an attempt to change his medication to sertindol has led to serious psychotic and somatic symptoms in an schizophrenic patient treated with clozapine for five years, however after readministration of clozapine these symptoms rapidly disappeared. To further analyse the case we have developed an HPLC method for the measurement of plasma levels of clozapine and its main metabolite N-desmethyl clozapine in order to monitor the plasma levels of clozapine and to correlate with the clinical symptoms. The present results confirmed that after discontinuation of clozapine no measurable amount of drug or its main metabolite were present in the plasma of the patient. The correlation between the plasma levels of clozapine and the changes in the clinical state of the patient confirmed that the patient's severe psychotic and somatic symptoms were the result of discontinuation of clozapine treatment. The clozapine plasma concentration of the patient reported here was low (100 ng/ml) compared to the generally accepted plasma levels for antipsychotic action of clozapine (350 ng/ml), however the somatic and psychotic clozapine withdrawal symptoms rapidly and completely disappeared.

    Rationale Once dependent on alcohol or opioids, negative affect may accompany withdrawal. Dependent individuals are hypothesized to “self-medicate” in order to cope with withdrawal, which promotes escalated drug or alcohol use. Objectives The current study aimed to develop a reliable animal model to assess symptoms that occur during spontaneous alcohol and opioid withdrawal. Methods Dependence was induced using intermittent alcohol exposure or pulsatile heroin delivery and assessed for the presence of withdrawal symptoms during acute withdrawal by measuring somatic signs, behavior in the forced swim test (FST) and air-puff induced 22-kHz ultrasonic vocalizations (USVs). Additional animals subjected to eight weeks of alcohol vapor exposure were evaluated for altered somatic signs, operant alcohol self-administration and 22-kHz USV production, as well as performance in the elevated plus-maze (EPM). Results During spontaneous withdrawal from pulsatile heroin or intermittent alcohol vapor, animals displayed increased somatic withdrawal signs, FST immobility and 22-kHz USV production, but did not show any behavioral change in the EPM unless the duration of exposure was extended to four weeks. Following eight weeks of alcohol vapor exposure, animals displayed somatic withdrawal signs, escalated alcohol self-administration and increased 22-kHz USVs. Conclusions These paradigms provide consistent methods to evaluate the behavioral ramifications, and neurobiological substrates, of alcohol and opioid dependence during spontaneous withdrawal. As immobility in the FST and percent open-arm time in the EPM were dissociable, with 22-kHz USVs paralleling immobility in the FST, assessment of air-puff induced 22-kHz USVs could provide an ethologically-valid alternative to the FST.

    Over 300,000 individuals enter treatment for cannabis-use disorders (CUDs) in the United States annually. Cannabis withdrawal is associated with poor CUD-treatment outcomes, but no prior studies have examined sex differences in withdrawal among treatment-seeking cannabis users. Treatment-seeking cannabis users (45 women and 91 men) completed a Marijuana Withdrawal Checklist (Budney, Novy, & Hughes, 1999, Budney, Moore, Vandrey, & Hughes, 2003) at treatment intake to retrospectively characterize withdrawal symptoms experienced during their most recent quit attempt. Scores from the 14-item Composite Withdrawal Discomfort Scale (WDS), a subset of the Marijuana Withdrawal Checklist that corresponds to valid cannabis withdrawal symptoms described in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; APA, 2013) were calculated. Demographic and substance-use characteristics, overall WDS scores, and scores on individual WDS symptoms were compared between women and men. Women had higher overall WDS scores than men, and women had higher scores than men on 6 individual symptoms in 2 domains, mood symptoms (i.e., irritability, restlessness, increased anger, violent outbursts), and gastrointestinal symptoms (i.e., nausea, stomach pain). Follow-up analyses isolating the incidence and severity of WDS symptoms demonstrated that women generally reported a higher number of individual withdrawal symptoms than men, and that they reported experiencing some symptoms as more severe. This is the first report to demonstrate that women seeking treatment for CUDs may experience more withdrawal then men during quit attempts. Prospective studies of sex differences in cannabis withdrawal are warranted.

    Adolescents higher in temperamental withdrawal are at risk for anxiety and depressive symptoms; however, not all youth higher in withdrawal exhibit internalizing symptoms, suggesting that contextual factors may influence these relationships. We examined whether youth withdrawal moderates the relationships between neighborhood processes (crime, social cohesion) and internalizing symptoms and whether findings were consistent with diathesis-stress or differential susceptibility hypotheses. Participants were 775 adolescents (M=15.50 ± 0.56 years, 72% male, 76% White). Adolescents higher in withdrawal manifested higher internalizing symptoms in the context of lower neighborhood crime and lower neighborhood social cohesion than youth lower in withdrawal, supporting diathesis-stress. These findings elucidate neighborhood processes associated with internalizing symptoms, which can inform models of risk and resilience for these symptoms among children who differ in temperamental withdrawal.

    Alcoholic patients suffer from harmful allostatic neuroplastic changes in the brain causing an acute withdrawal syndrome upon cessation of drinking followed by a protracted abstinence syndrome and an increased risk of relapse to heavy drinking. Benzodiazepines have long been the treatment of choice for detoxifying patients and managing alcohol withdrawal syndrome (AWS). Non-benzodiazepine anticonvulsants (NBACs) are increasingly being used both for alcohol withdrawal management and for ongoing outpatient treatment of alcohol dependence, with the goal of either abstinence or harm reduction. This expert narrative review summarizes the scientific basis and clinical evidence supporting the use of NBACs in treating AWS and for reducing harmful drinking patterns. There is less evidence in support of NBAC therapy for AWS, with few placebo-controlled trials. Carbamazepine and gabapentin appear to be the most promising adjunctive treatments for AWS, and they may be useful as monotherapy in select cases, especially in outpatient settings and for the treatment of mild-to-moderate low-risk patients with the AWS. The body of evidence supporting the use of the NBACs for reducing harmful drinking in the outpatient setting is stronger. Topiramate appears to have a robust effect on reducing harmful drinking in alcoholics. Gabapentin is a potentially efficacious treatment for reducing the risk of relapse to harmful drinking patterns in outpatient management of alcoholism. Gabapentin's ease of use, rapid titration, good tolerability, and efficacy in both the withdrawal and chronic phases of treatment make it particularly appealing. In summary, several NBACs appear to be beneficial in treating AWS and alcohol use disorders.

    Increasingly, addicted inmates admitted to jail in New Mexico are in the process of opiate withdrawal. While the standard for opiate detoxification is a narcotic taper, correctional policy restricts opiate use for safety reasons. An alternative for withdrawal is a supportive intervention with clonidine, a non-opiate. Could clonidine be beneficial for acute opiate withdrawal symptoms in this population? Fifty-five inmates (37 male and 18 female) volunteered to participate in assessing clonidine for the reduction of withdrawal symptoms. Symptoms were assessed with the Subjective Opiate Withdrawal Scale and treated with a standard clonidine protocol. Clonidine significantly decreased the mean scores at 1 and 4 hours after medication use. Clonidine for opiate withdrawal reduces symptoms when opiate-assisted detoxification is not available.

    Alcohol withdrawal is associated with hypothalamic–pituitary–adrenal (HPA) axis dysfunction. The FKBP5 gene codes for a co-chaperone, FK506-binding protein 5, that exerts negative feedback on HPA axis function. This study aimed to examine the effects of single-nucleotide polymorphisms (SNPs) of the FKBP5 gene in humans and the effect of Fkbp5 gene deletion in mice on alcohol withdrawal severity. We genotyped six FKBP5 SNPs (rs3800373, rs9296158, rs3777747, rs9380524, rs1360780, and rs9470080) in 399 alcohol-dependent inpatients with alcohol consumption 48 h before admission and recorded scores from the Clinical Institute Withdrawal Assessment-Alcohol revised (CIWA-Ar). Fkbp5 gene knockout (KO) and wild-type (WT) mice were assessed for alcohol withdrawal using handling-induced convulsions (HICs) following both acute and chronic alcohol exposure. We found the minor alleles of rs3800373 (G), rs9296158 (A), rs1360780 (T), and rs9470080 (T) were significantly associated with lower CIWA-Ar scores whereas the minor alleles of rs3777747 (G) and rs9380524 (A) were associated with higher scores. The haplotype-based analyses also showed an association with alcohol withdrawal severity. Fkbp5 KO mice showed significantly greater HICs during withdrawal from chronic alcohol exposure compared with WT controls. This study is the first to show a genetic effect of FKBP5 on the severity of alcohol withdrawal syndrome. In mice, the absence of the Fkbp5 gene enhances sensitivity to alcohol withdrawal. We suggest that FKBP5 variants may trigger different adaptive changes in HPA axis regulation during alcohol withdrawal with concomitant effects on withdrawal severity. PMID:24603855

    A few case reports and data from animal experiments point to a possible efficacy of gabapentin (GP) in the treatment of alcohol withdrawal syndrome (AWS). Because of ethical considerations, the efficacy of GP in acute AWS was tested in an add-on fashion to clomethiazole (CLO). Given that the symptom-triggered amount of CLO required to limit AWS within the first 24 hours is related to the severity of AWS, we tested this amount of CLO during placebo (P) or GP (400 mg qid) under double blind, randomized conditions. Sixty-one patients (P = 29/GP = 32) suffering from alcohol dependence (ICD-10) and without any other psychiatric condition or psychotropic medication were included. The groups were not significantly different in baseline characteristics (eg, demographic data, severity of AWS). Both ITT and completer analyses revealed no significant differences between the groups considering the primary effectiveness measure: amount of CLO required in the first 24 hours (P = 6.1 +/- 5.4/GP = 6.2 +/- 4.7 capsules). In addition, premature discontinuations (P = 3/GP = 2) and decreases in Mainz Alcohol Withdrawal Scores were not significantly different in the first 48 hours of AWS (secondary effectiveness measures). Tolerability of combined CLO/GP was studied throughout the whole treatment comprising a 5-day lasting reduction part subsequent to the first 48 hours. Throughout the whole 7-day treatment a total of 5 and 2 patients dropped out and 6 and 5 patients reported adverse clinical events in the P and GP groups, respectively. All together, GP (400 mg qid) was no better than P in saving initial consumption of CLO or decreasing initial Mainz Alcohol Withdrawal Scores suggesting that GP was ineffective in the management of acute AWS in this model. The combination of GP and CLO was safe.

    Preclinical and clinical studies suggest that individual drug withdrawal symptoms may have differential effects on addictive behaviors. The goals of this study were (1) to explore the dimensions of DSM-IV cocaine withdrawal symptoms and (2) to examine the association of these dimension and individual withdrawal symptoms with problems related to drug dependence in male and female cocaine users. The results of the principal components analyses of withdrawal symptoms supported a two factor model. The first one is labeled the depressive symptoms factor and included symptoms of depressed mood, psychomotor agitation, psychomotor retardation, craving for cocaine, insomnia, and vivid, unpleasant dreams. The second factor labeled the somatic symptoms factor included symptoms of increased appetite, hypersomnia, and fatigue. The depressive symptoms factor, in comparison to the somatic symptoms factor, was associated with more frequent reporting of having chemical dependency treatment, having depressed mood for longer than 2 weeks, and trading cocaine for sex. When the individual withdrawal symptoms were examined, depressed mood, psychomotor agitation, vivid, unpleasant dreams, and fatigue were associated with more frequent reporting of some of these outcomes. Our findings support two dimensions in cocaine withdrawal symptoms with differential effects on cocaine dependence outcomes.

    Rationale Disrupted social behavior, including occasional aggressive outbursts, is characteristic of withdrawal from long-term alcohol (EtOH) use. Heavy EtOH use and exaggerated responses during withdrawal may be treated using glutamatergic N-methyl-D-aspartate receptor (NMDAR) antagonists. Objectives The current experiments explore aggression and medial prefrontal cortex (mPFC) glutamate as consequences of withdrawal from intermittent access to EtOH, and changes in aggression and mPFC glutamate caused by NMDAR antagonists memantine and ketamine. Methods Swiss male mice underwent withdrawal following 1-8 weeks of intermittent access to 20% EtOH. Aggressive and non-aggressive behaviors with a conspecific were measured 6-8 h into EtOH withdrawal after memantine or ketamine (0-30 mg/kg, i.p.) administration. In separate mice, extracellular mPFC glutamate after memantine was measured during withdrawal using in vivo microdialysis. Results At 6-8 h withdrawal from EtOH, mice exhibited more convulsions and aggression, and decreased social contact compared to age-matched water controls. Memantine, but not ketamine, increased withdrawal aggression at the 5 mg/kg dose in mice with a history of 8 weeks EtOH but not 1 or 4 weeks of EtOH or in water drinkers. Tonic mPFC glutamate was higher during withdrawal after 8 weeks EtOH compared to 1 week EtOH or 8 weeks water. Five mg/kg memantine increased glutamate in 8 week EtOH mice, but also in 1 week EtOH and water drinkers. Conclusions These studies reveal aggressive behavior as a novel symptom of EtOH withdrawal in outbred mice and confirm a role of NMDARs during withdrawal aggression and for disrupted social behavior.

    In this paper, we propose a signal processing method of assessing the severity tremors caused by alcohol withdrawal (AW) syndrome. We have developed an iOS application to calculate the Clinical Institute Withdrawal Assessment (CIWA) score which captures iPod movements using the built-in accelerometer in order to reliably estimate the tremor severity component of the score. We report on the characteristics of AW tremor, the accuracy of electronic assessment of tremor compared to expert clinician assessment, and the potential for using signal processing assessment to differentiate factitious from real tremor in patients seen in the emergency department, as well as in nurses mimicking a tremor. Our preliminary results are based on 84 recordings from 61 subjects (49 patients, 12 nurses). In general we found a linear relationship between energy measured by the accelerometer (in the 4.4-10 Hz range) and the expert rating of tremor severity. Additionally, we demonstrate that 75% of the recordings from patients with actual AW syndrome had a mean peak frequency higher than 7 Hz whereas only 17% of the nurses' factitious tremors were above 7 Hz, suggesting that tremor above 7 Hz could be a potential discriminator of real versus factitious tremors.

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

    Electronic cigarette (e-cigarette) use is becoming increasing popular among smokers, and there is a plethora of devices available. Nicotine delivery is clearly important for reducing tobacco craving and withdrawal symptoms, but other sensorimotor aspects of e-cigarettes (such as visual appearance) may contribute to this effect. This study explored whether it is important for an e-cigarette to visually resemble a tobacco cigarette in order to reduce craving and withdrawal symptoms. Sixty-three cigarette smokers (40% female, aged 18-65 years) who were not current e-cigarette users were randomly allocated to take ten 3-s puffs from either a white or a red first-generation e-cigarette following overnight abstinence. Current craving (urge to smoke) and nicotine withdrawal symptoms (using the Mood and Physical Symptoms Scale [MPSS]) were measured before and 10 min after use. Linear regression revealed higher craving and withdrawal symptoms in the red condition versus the white condition, but only among those who were e-cigarette naive (craving: B = .76, p = .009; withdrawal symptoms: B = 2.18, p = .009), not among those with e-cigarette experience (craving: B = -.08, p = .89; withdrawal symptoms: B = .24, p = .81), and these effects differed between groups (p = .04 and 0.01 for craving and withdrawal symptoms, respectively). In conclusion, cigarette-like appearance was associated with lower craving and withdrawal symptoms, but only for those with no prior e-cigarette experience. This effect, putatively mediated via classical conditioning or expectancies, may aid understanding of smokers' initial preferences for "cigalike" e-cigarette devices.

    Genetic factors significantly affect vulnerability to alcohol dependence (alcoholism). We previously identified quantitative trait loci on distal mouse chromosome 1 with large effects on predisposition to alcohol physiological dependence and associated withdrawal following both chronic and acute alcohol exposure in mice (Alcdp1 and Alcw1, respectively). We fine-mapped these loci to a 1.1–1.7 Mb interval syntenic with human 1q23.2-23.3. Alcw1/Alcdp1 interval genes show remarkable genetic variation among mice derived from the C57BL/6J and DBA/2J strains, the two most widely studied genetic animal models for alcohol-related traits. Here, we report the creation of a novel recombinant Alcw1/Alcdp1 congenic model (R2) in which the Alcw1/Alcdp1 interval from a donor C57BL/6J strain is introgressed onto a uniform, inbred DBA/2J genetic background. As expected, R2 mice demonstrate significantly less severe alcohol withdrawal compared to wild-type littermates. Additionally, comparing R2 and background strain animals, as well as reciprocal congenic (R8) and appropriate background strain animals, we assessed Alcw1/Alcdp1 dependent brain gene expression using microarray and quantitative PCR analyses. To our knowledge this includes the first Weighted Gene Co-expression Network Analysis using reciprocal congenic models. Importantly, this allows detection of co-expression patterns limited to one or common to both genetic backgrounds with high or low predisposition to alcohol withdrawal severity. The gene expression patterns (modules) in common contain genes related to oxidative phosphorylation, building upon human and animal model studies that implicate involvement of oxidative phosphorylation in alcohol use disorders (AUDs). Finally, we demonstrate that administration of N-acetylcysteine, an FDA-approved antioxidant, significantly reduces symptoms of alcohol withdrawal (convulsions) in mice, thus validating a phenotypic role for this network. Taken together, these studies

    Chronic intermittent access to alcohol leads to the escalation of alcohol intake, similar to binge drinking in humans. Converging lines of evidence suggest that impairment of medial prefrontal cortex (mPFC) cognitive function and overactivation of the central nucleus of the amygdala (CeA) are key factors that lead to excessive drinking in dependence. However, the role of the mPFC and CeA in the escalation of alcohol intake in rats with a history of binge drinking without dependence is currently unknown. To address this issue, we examined FBJ murine osteosarcoma viral oncogene homolog (Fos) expression in the mPFC, CeA, hippocampus, and nucleus accumbens and evaluated working memory and anxiety-like behavior in rats given continuous (24 h/d for 7 d/wk) or intermittent (3 d/wk) access to alcohol (20% vol/vol) using a two-bottle choice paradigm. The results showed that abstinence from alcohol in rats with a history of escalation of alcohol intake specifically recruited GABA and corticotropin-releasing factor (CRF) neurons in the mPFC and produced working memory impairments associated with excessive alcohol drinking during acute (24–72 h) but not protracted (16 –68 d) abstinence. Moreover, abstinence from alcohol was associated with a functional disconnection of the mPFC and CeA but not mPFC and nucleus accumbens. These results show that recruitment of a subset of GABA and CRF neurons in the mPFC during withdrawal and disconnection of the PFC–CeA pathway may be critical for impaired executive control over motivated behavior, suggesting that dysregulation of mPFC interneurons may be an early index of neuroadaptation in alcohol dependence.

    Association studies implicate the multiple PDZ domain protein (MUPP1/MPDZ) gene in risk for alcoholism in humans and alcohol withdrawal in mice. Although manipulation of the Mpdz gene by homologous recombination and bacterial artificial chromosome transgenesis has suggested that its expression affects alcohol withdrawal risk, the potential confounding effects of linked genes and developmental compensation currently limit interpretation. Here, using RNA interference, we directly test the impact of Mpdz expression on alcohol withdrawal severity and provide brain regional mechanistic information. Lentiviral-mediated delivery of Mpdz short hairpin RNA (shRNA) to the caudolateral substantia nigra pars reticulata significantly reduces Mpdz expression and exacerbates alcohol withdrawal convulsions compared to control mice delivered a scrambled shRNA. Neither baseline nor pentylenetetrazol enhanced convulsions differed between Mpdz shRNA and control animals, indicating that Mpdz expression in the caudolateral substantia nigra pars reticulata does not generally affect seizure susceptibility. To our knowledge, these represent the first in vivo Mpdz RNA interference analyses, and provide the first direct evidence that Mpdz expression impacts behavior. Our results confirm that Mpdz is a quantitative trait gene for alcohol withdrawal and demonstrate that its expression in the caudolateral substantia nigra pars reticulata is crucially involved in risk for alcohol withdrawal.

    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 spectrometry (MRS), positron emission tomography (PET), and single photon emission computed tomography (SPECT) in studies of alcohol dependence and withdrawal. We focus on studies interrogating γ-aminobutryic 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, e.g., 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.

    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 investigated alcohol intoxication behavior and withdrawal severity using a modified Majchrowicz model of alcohol dependence that has been shown to result in similar blood ethanol concentrations (BECs) despite age differences. Adolescent (postnatal day, PND, 35) and adult rats (PND 70+) received ethanol according to this 4-day binge paradigm and were observed for withdrawal behavior for 17h. As expected, adolescents showed decreased sensitivity to alcohol-induced CNS depression as evidenced by significantly lower intoxication scores. Thus, adolescents received significantly more ethanol each day (12.3+/-0.1g/kg/day) than adults (9.2+/-0.2g/kg/day). Despite greater ethanol dosing in adolescent rats, both adolescent and adult groups had comparable peak BECs (344.5+/-10.2 and 338.5+/-7.8mg/dL, respectively). Strikingly, withdrawal severity was similar quantitatively and qualitatively between adolescent and adult rats. Further, this is the first time that withdrawal behavior has been reported for adolescent rats using this model of alcohol dependence. A second experiment confirmed the similarity in BECs at various time points across the binge. These results demonstrate that after consideration of ethanol pharmacokinetics between adults and adolescents by using a model that produces similar BECs, withdrawal severity is nearly identical. This study, in combination with previous reports on ethanol withdrawal in adolescents and adults, suggests only a BEC-dependent effect of ethanol on

    OBJECTIVE--To investigate the prevalence of arrhythmias in alcoholic men during detoxification and its relation to neuroendocrine activation and electrolyte disturbances. DESIGN--Consecutive case-control study. SETTING--Primary and secondary care, detoxification ward. PATIENTS AND CONTROLS--19 otherwise healthy alcoholic men (DSM-III-R) with withdrawal symptoms necessitating detoxification in hospital. 19 age matched, healthy non-alcoholic men as controls for Holter recordings. INTERVENTIONS--Treatment with chlomethiazole; additional treatment with carbamazepine in patients with previous seizures. MAIN OUTCOME MEASURES--Computer based analyses of mean heart rate and arrhythmias from 24 hour Holter recordings, 24 hour urinary excretion of adrenaline and noradrenaline, magnesium retention measured by means of intravenous loading test, and serum concentrations of electrolytes. RESULTS--The 24 hour mean heart rate was higher in the alcoholic men (97.4 beats/minute, 95% confidence interval (CI) 91.2 to 103.6) than in the controls (69.6 beats/minute, 95% CI 65.4 to 73.8, P < 0.001). However, there was no difference in diurnal heart rate variation. The prevalence of premature supraventricular depolarisations was lower in the alcoholic men (P < 0.05). Neither atrial fibrillation nor malignant ventricular arrhythmias occurred. The sinus tachycardia in the alcoholic men correlated with the concomitant urinary excretion of catecholamines (P < 0.05). The mean serum magnesium concentration was 0.78 mmol/l (95% CI 0.73 to 0.83) in the alcoholic men and 0.83 mmol/l (95% CI 0.81 to 0.85) in a reference population of 55 men aged 40. Magnesium depletion (defined as magnesium retention > 30%) was detected in 10 alcoholic men (53%). Three alcoholic men had serum potassium concentrations < or = 3.3 mmol/l on admission. CONCLUSION--Increased adrenergic activity, magnesium depletion, and hypokalaemia are often seen after heavy drinking, but in alcoholic men without clinical heart disease

    In the present study, we examined the effects of acamprosate for its ability to reduce handling induced convulsions (HICs) during alcohol withdrawal. Diazepam was used as a positive control. Swiss Webster male mice received three daily IP injections of alcohol (2.5 g/kg) or alcohol (2.5 g/kg)+methylpyrazole (4-MP) (9 mg/kg). (4-MP, being an alcohol dehydrogenase inhibitor slows down the breakdown of alcohol. 4-MP in combination with alcohol exhibits a dramatic increase in blood alcohol level compared to alcohol alone). Ten hours following the last alcohol injection, the mice were picked up by the tail and examined for their seizure susceptibility (HICs). Diazepam, a benzodiazepine known to reduce seizures during alcohol withdrawal, significantly reduced these HICs at doses of 0.25, 0.5 and 1 mg/kg (p's<0.001). Acamprosate, an anti-relapse compound used clinically in newly abstinent alcoholics, also reduced these HICs at doses of 100, 200 and 300 mg/kg (p's<0.05). This study supports the use of acamprosate during periods of alcohol withdrawal as well as during abstinence.

    Gamma-hydroxybutyrate (GHB) is a short chain fatty acid endogenously produced within the central nervous system (CNS) and acts as a precursor and metabolite of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). Although, it is an illegal recreational drug of abuse, its sodium salt (sodium oxybate) has been utilized as a medication for a number of medical conditions. The first aim of this review was to focus on current applications of sodium oxybate for the treatment of narcolepsy, with a particular emphasis on the key symptoms of this disorder: cataplexy and excessive daytime sleepiness (EDS). Secondly, the effectiveness of sodium oxybate therapy for the treatment of alcohol withdrawal syndrome (AWS) and the maintenance of alcohol abstinence has been assessed. Nowadays, sodium oxybate is the first-line treatment for narcolepsy and it is highly effective in meliorating sleep architecture, decreasing EDS and the frequency of cataplexy attacks in narcoleptic patients. Sodium oxybate currently finds also application in the treatment of AWS and the maintenance of alcohol abstinence in alcoholics. Most of the studies evaluating the efficacy of GHB in the treatment of AWS use a dosage of 50 mg/kg divided in three or four administrations per day. Human studies showed that GHB (dose of 50 mg/kg, divided in three administrations per day) is capable to increase the number of abstinent days, reduce alcohol craving and decrease the number of drinks per day. However, there is limited randomized evidence and, thus, GHB cannot be reliably compared to clomethiazole or benzodiazepines. Some randomized data suggest that GHB is better than naltrexone and disulfiram regarding abstinence maintenance and prevention of craving in the medium term i.e. 3-12 months. It is recommended that GHB should be used only under strict medical supervision, since concerns about the abuse/misuse of the drug and the addiction potential have been arisen.

    Dopaminergic transmission has been suggested to be a main mechanism mediating reinforcement, withdrawal and craving in alcohol dependency. Dopamine is associated with prolactin secretion, acting as a prolactin inhibitor. The aim of the present study was to investigate whether there is an association between altered prolactin levels and craving during early and late alcohol withdrawal. Therefore, we examined 145 patients suffering from alcohol dependency after admission to the detoxification unit, assessing craving with the Obsessive Compulsive Drinking Scale (OCDS) and measuring prolactin serum levels during early withdrawal (-EW: day 0 or day 1) and late withdrawal (-LW: day 7-day 10). We observed a significant influence of the alteration of prolactin during withdrawal on craving in female patients (Spearman's rho, OCDS-EW: r=-0.607, p=0.001; OCDS-LW: r=-0.730, p<0.001; n=26). The association between prolactin alteration in percentage and craving in females was confirmed with general linear models (OCDS-EW: F=15.819, p=0.001, r(2)=0.530; OCDS-LW: F=17.091, p<0.001, r(2)=0.535). In male patients we did not find any significant results. Our findings support the previously described role of the hypothalamic-pituitary-adrenal (HPA) axis in the neurobiology of alcohol craving and show evidence of an association between increased prolactin serum levels and lower craving during alcohol withdrawal in female patients.

    Bupropion's (Zyban(®) SR) effectiveness to treat symptoms experienced in marihuana withdrawal was tested in a double-blind, placebo-controlled study with chronic, heavy marihuana users. Participants maintained their usual marihuana intake until Quit Day after which they were required to cease intake of THC products for 14 days. A Withdrawal Discomfort Score revealed that for 7 days immediately following cessation, placebo-treated subjects reported more symptoms than bupropion-treated subjects. Self-reported craving for marihuana increased for the placebo-treated group but not for those treated with bupropion. Measures of sleep and cognitive performance were not different between the two groups. Participants in the bupropion treatment arm were more likely to complete the study than those randomized to the placebo arm (50% completion for bupropion vs. 33% completion for placebo). These results suggest that bupropion may be useful for alleviating marihuana withdrawal symptoms and be useful in subject retention during long-term cessation programs.

    This study was designed to assess the effect of controlled deep breathing on smoking withdrawal symptoms. In two laboratory sessions, dependent smokers refrained from smoking for 4 h. During a deep breathing session, participants were instructed to take a series of deep breaths every 30 min. During a control session, participants sat quietly. Controlled deep breathing significantly reduced smoking withdrawal symptoms, including craving for cigarettes and negative affect (tense, irritable), while resulting in the maintenance of baseline arousal (wide awake, able to concentrate) levels. Furthermore, a history of heavy smoking was associated with greater increases in arousal during the deep breathing session. The results of this preliminary study suggest that controlled deep breathing may be useful for relieving symptoms of smoking withdrawal.

    Relieving withdrawal and post-abstinence syndrome of alcoholism is one of the major strategies in the treatment of alcohol addicted patients. Diazepam, chlordiazepoxide, and topiramate are the approved medications that were used for this object. To assess the role of non-pharmacologic therapy in the management of alcohol withdrawal syndrome, we analyzed effects of forced exercise by treadmill on alcohol dependent mice as an animal model. A total of 60 adult male mice were divided into 5 groups, from which 4 groups became dependent to alcohol (2 g/kg/day) for 15 days. From day 16, treatment groups were treated by diazepam (0.5mg/kg), forced exercise, and diazepam (0.5 mg/kg) concurrent with forced exercise for two weeks; And the positive control group received same dose of alcohol (2 g/kg/day) for two weeks. The negative control group received normal saline for four weeks. Finally, on day 31, all animals were observed for withdrawal signs, and Alcohol Total Withdrawal Score (ATWS) was determined. Blood cortisol levels were measured in non-fasting situations as well. Present findings showed that ATWS significantly decrease in all treatment groups in comparison with positive control group (P<0.05 for groups received diazepam and treated by forced exercise and P<0.001 for group under treatment diazepam + forced exercise). Moreover, blood cortisol level significantly decreased in all treatment groups (P<0.001). This study suggested that forced exercise and physical activity can be useful as adjunct therapy in alcoholism and can ameliorate side effects and stress situation of withdrawal syndrome periods.

    Based on the knowledge that alcohol misuse causes a multitude of diseases and increased mortality, this systematic review examines whether a reduction of the individual alcohol consumption can contribute to a minimization of health risks within a harm reduction approach. In fact, the reviewed 63 studies indicate that interventions aiming at alcohol reduction (including total abstinence as one possible therapeutic aim) indeed resulted in or were associated with positive effects in harmful, hazardous or alcohol-dependent drinkers. Major benefits were observed for reducing alcohol-associated injuries, recovery of ventricular heart function in alcoholic cardiomyopathy, blood pressure lowering, normalization of biochemical parameter, body weight reduction, histological improvement in pre-cirrhotic alcohol-related liver disease and slowed progression of an already existing alcohol-attributable liver fibrosis. Furthermore, reduced withdrawal symptoms, prevalence of psychiatric episodes and duration of in-patient hospital days, improvement of anxiety and depression symptoms, self-confidence, physical and mental quality of life, fewer alcohol-related adverse consequences as well as lower psychosocial stress levels and better social functioning can result from reduced alcohol intake. The reviewed literature demonstrated remarkable socioeconomic cost benefits in areas such as the medical health-care system or workforce productivity. Individuals with heightened vulnerability further benefit significantly from alcohol reduction (e.g. hypertension, hepatitis C, psychiatric co-morbidities, pregnancy, but also among adolescents and young adults). Concluding, the reviewed studies strongly support and emphasize the importance and benefits of early initial screening for problematic alcohol use followed by brief and other interventions in first contact medical health-care facilities to reduce alcohol intake.

    The study aims at investigating the relationship between hypothalamic-pituitary-adrenal (HPA) axis alterations and aggression level in alcoholic patients during early and late alcohol withdrawal. Serum levels of basal cortisol and dehydroepiandrosterone sulphate (DHEAS) were measured three times, and cortisol and DHEAS response to dexamethasone twice during the early and late withdrawal periods in alcohol dependent males (n=30) and once in healthy control males (n=20). Abnormal cortisol non-suppression response to dexamethasone in dexamethasone suppression test (DST) was observed in some proportion of the patients in early withdrawal, which normalized in late withdrawal. The study revealed reduced basal DHEAS levels and reduced DHEAS response to dexamethasone in late withdrawal. When the patients were assessed in two separate groups as high- and low-aggressives, in the high-aggression group abnormality in DST was observed during both early and late withdrawal periods, in the low-aggression group it was observed only in early withdrawal. While basal DHEAS levels were low in the high-aggression group only in early withdrawal, it was reduced in the low-aggression group during late withdrawal period. Some alterations of the HPA axis during alcohol withdrawal might be associated not only with alcohol use per se but also with aggressivity tendency of alcoholic patients.

  13. Pharmacological evaluation of alcohol withdrawal-induced inhibition of exploratory behaviour and supersensitivity to harmine-induced tremor.

    PubMed

    1994-01-01

    Rats given a liquid diet containing 10% (v/v) alcohol consume high quantities of alcohol. Within 8 hr after cessation of the alcohol intake, the animals will show alcohol-withdrawal reactions including a supersensitivity to harmine-induced tremor and an inhibition of exploratory behaviour in a neutral environment. Several drugs can overcome one or more of these alcohol-withdrawal reactions. A reduction of the alcohol withdrawal-induced inhibition of exploration, in terms of both the number of transits into the open field and the time spent in the open field, was obtained with chlordiazepoxide, ritanserin, mianserin and propranolol. Of these four compounds, propranolol and mianserin were also active against the supersensitivity to both 5.00 and 10.00 mg/kg harmine-induced tremor. Chlordiazepoxide and ritanserin were only active against 5.00 mg/kg harmine. Other compounds that reversed the supersensitivity to harmine-induced tremor during alcohol withdrawal included buspirone, fluoxetine, haloperidol, clonidine, flunarizine and baclofen. Very limited effects on both alcohol-withdrawal reactions were observed with ondansetron, nimodipine and MK-801. Risperidone and SCH 23390 were inactive. These results demonstrate that some alcohol withdrawal reactions can be studied in a systematic way and that various pharmacological agents can differentially interact with these alcohol withdrawal reactions.

    Yulangsan polysaccharide (YLSP) has been utilized as a phytomedicine to managing nervous dysfunction in China. Thus, this study aimed to evaluate the potential YLSP-mediated detoxification role against morphine dependence in rats. The results indicated that the morphine dependence model significantly increased withdrawal symptoms, levels of NO and NOS (P<0.05). Furthermore, monoaminergic neurotransmitters, including DA and NE, were detected at elevated levels in the ventral tegmental area (VTA), hippocampus (HIP) and prefrontal cortex (PFC), respectively, while the level of DA was decreased and NE was increased in the nucleus accumbens (NAc). Conversely, YLSP administration significantly reversed naloxone-induced withdrawal symptoms, expression of brain NO and NOS, and monoaminergic neurotransmitters (P<0.05). Interestingly, YLSP shows an even more effective trend in attenuating withdrawal symptoms than does clonidine, although without a significant difference. These findings indicate that YLSP attenuation of the naloxone-induced withdrawal symptoms of morphine dependence may be mediated by regulation of the NO pathway and modulation of monoaminergic neurotransmitters.

    Cannabis is the most widely used illicit drug in the United States, yet the role of genetics in individual symptoms associated with cannabis use disorders has not been evaluated. The purpose of the present set of analyses was to describe the symptomatology and estimate the heritability of DSM-IV criteria/symptoms of cannabis dependence in a large sample of families. Participants were 2524 adults, participating in the University of California San Francisco (UCSF) Family Study of alcoholism. Seventy percent of the sample had ever used cannabis and 13.9% met DSM-IV criteria for cannabis dependence. Younger age at first cannabis use was found to be significantly associated with a shortened survival to becoming cannabis dependent. Although a greater percentage of men met criteria for cannabis dependence, women were found to demonstrate “telescoping” as indexed by a shorter survival time from initial use to dependence as compared to men. A cannabis withdrawal syndrome was identified in users, the primary symptoms of which were nervousness, appetite change, and sleep disturbance. Cannabis use (h2 = 0.31) and dependence (h2 = 0.20), age at first use, individual DSM-IV criteria for dependence, and cannabis-use associated symptoms of depression, trouble concentrating and paranoia were all found to be heritable. These findings suggest that within this population that cannabis use and dependence, as well as individual cannabis dependence symptoms have a significant heritable component, that cannabis dependence is more likely to occur when use begins during adolescence, and that the cannabis dependence syndrome includes a number of heritable untoward psychiatric side effects including withdrawal.

  16. Environmental enrichment may protect against neural and behavioural damage caused by withdrawal from chronic alcohol intake.

    Exposure to stress and prolonged exposure to alcohol leads to neuronal damages in several brain regions, being the medial prefrontal cortex (mPFC) one of the most affected. These changes presumably reduce the ability of the organism to cope with these stimuli and may underlie a series of maladaptive behaviours among which include drug addiction and withdrawal. Drug-addicted individuals show a pattern of behavior similar to patients with lesions of the mPFC. This impairment in the decision-making could be one of the mechanisms responsible for the transition from the casual to compulsive drug use. The environmental enrichment (EE) has a protective effect on the neural and cognitive impairments induced by psychoactive drugs, including ethyl alcohol. The present study aims to determine the influence of withdrawal from intermittent long-term alcohol exposure on alcohol preference, emotional reactivity and neural aspects of early isolated or grouped reared rats kept under standard or complex environments and the influence of social isolation on these measures, as well. Our results point out new insights on this matter showing that the EE can attenuate the adverse effects of withdrawal and social isolation on rat's behavior. This effect is probably due to its protective action on the mPFC integrity, including the cingulate area 1 (Cg1), and the prelimbic (PrL) and infralimbic cortex (IL), what could account for the absence of changes in the emotional reactivity in EE alcohol withdrawal rats. We argue that morphological changes at these cortical levels can afford the emotional, cognitive and behavioural dysregulations verified following withdrawal from chronic alcohol intake.

    This study was designed to examine the effect of environmental enrichment during METH administration on the behavioral withdrawal symptoms after drug abstinence in rats. Rats reared in standard (SE) or enriched environment (EE) during induction of METH dependence with bi-daily injections of METH (2mg/kg, at 12-h. intervals) for 14 days. Then, rats were evaluated for behavioral withdrawal symptoms, and also for anxiety (elevated plus maze-EPM) and depression (Forced swim test-FST) over a ten day period of abstinence. The results showed that stereotypic behaviors score and the number of rearing were significantly lower in METH/EE rats compared to the SE group during 1-4 days. Also, The METH/EE group exhibited more weight gain during 6-10 days of abstinence. The METH/EE rats exhibited lower levels of immobility after METH abstinence than control group in the FST. EE had no effect on anxiety-like behavior. This study showed that exposure to EE diminished the severity of withdrawal symptoms and depressive-like behavior during spontaneous withdrawal from METH.

    We examined heterogeneity in risk for externalizing symptoms in children of alcoholic parents as it may inform the search for entry points into an antisocial pathway to alcoholism. Specifically, we tested whether the number of alcoholic parents in a family, the comorbid subtype of parent alcoholism, and the gender of the child predicted trajectories of externalizing symptoms over the early life course as assessed in high-risk samples of children of alcoholic parents and matched controls. Through integrative analyses of two independent, longitudinal studies, we showed that children with either antisocial alcoholic parents or two alcoholic parents were at greatest risk for externalizing symptoms. Moreover, children with a depressed alcoholic parent did not differ from those with an antisocial alcoholic parent in reported symptoms. These findings were generally consistent across mother-, father- and adolescent-reports of symptoms, child gender and child age (ages 2 through 17), and the two independent studies examined. Multi-alcoholic and comorbid-alcoholic families may thus convey a genetic susceptibility to dysregulation along with environments that both exacerbate this susceptibility and provide few supports to offset it.

    This study utilized a life history approach to describe clients' psychological experiences of the alcohol withdrawal process while voluntarily residing in a specialist alcohol withdrawal facility. Reflection on the past and anticipation of the future frequently occupied the thoughts of participants as they sought insight in to their lives. These insights were associated with a range of emotions that included embarrassment, shame, optimism, feelings of support and a sense of loss of control. The findings provide additional information on the human experience of alcohol withdrawal and, thus, increase empathy, understanding and knowledge. This increased understanding can be utilized to improve the quality of nursing care provided to this complex client group.

    Animal experiments suggest that endogenous substances that could result from the interaction between neurotransmitters (dopamine and indoleamines) and ethanol and its metabolite acetaldehyde might be involved in the pathogenesis and maintenance of alcohol dependence. Therefore, aromatic beta-carbolines (norharman and harman) were investigated repeatedly in 24-hr urine of 13 male severe alcoholics without any psychiatric comorbidity during a controlled inpatient abstention program of up to 8 weeks. Harman excretion was approximately 2-fold above levels in control subjects, with a steady decline after 3 weeks of abstinence and lower levels in patients with a longer duration of alcohol dependence. Severity of withdrawal symptoms and actual feelings of anxiety/depression were negatively associated with urinary harman excretion. Positive associations could be established with daily ethanol consumption the month before admission and the score on the scale "reward dependence" according to Cloninger's Tridimensional Personality Questionnaire. Moreover, patients without alcohol-dependent first-degree relatives and higher "reward dependence" exhibited an increased excretion of harman. Therefore, harman levels might characterize a distinct subgroup of alcoholic patients, who in part resemble the so-called type l alcoholics of Cloninger. However, this awaits further study in a larger number of individuals. In contrast, norharman excretion was elevated up to 6-fold, compared with nonalcoholics over 6 to 8 weeks of controlled abstention. No correlations to demographic or clinical variables could be observed. Therefore, increased norharman levels might be proposed as a "residual marker" or a trait variable. Whether the observed changes are specific markers of at least certain aspects of alcoholism or dependence remain to be elucidated.

    Bupropion’s (Zyban® SR) effectiveness to treat symptoms experienced in marihuana withdrawal was tested in a double-blind, placebo-controlled study with chronic, heavy marihuana users. Participants maintained their usual marihuana intake until Quit Day after which they were required to cease intake of THC products for 14 days. A Withdrawal Discomfort Score revealed that for 7 days immediately following cessation, placebo-treated subjects reported more symptoms than bupropion-treated subjects. Self-reported craving for marihuana increased for the placebo-treated group but not for those treated with bupropion. Measures of sleep and cognitive performance were not different between the two groups. Participants in the bupropion treatment arm were more likely to complete the study than those randomized to the placebo arm (50% completion for bupropion vs. 33% completion for placebo). These results suggest that bupropion may be useful for alleviating marihuana withdrawal symptoms and be useful in subject retention during long-term cessation programs. PMID:22879754

  2. Altered voltage-gated calcium channels in rat inferior colliculus neurons contribute to alcohol withdrawal seizures.

    We have previously reported that enhanced susceptibility to alcohol withdrawal seizures (AWS) parallels the enhancement of the current density of high-threshold voltage-gated Ca(2+) (CaV) channels in rat inferior colliculus (IC) neurons. However, whether this increased current density is a cause or consequence of AWS is unclear. Here, I report changes in the current density of CaV channels in IC neurons during the course of alcohol withdrawal and the potential anticonvulsant effect of intra-IC infusions of L- and P-type CaV channel antagonists. Whole-cell currents were activated by depolarizing pulses using barium as the charge carrier. Currents and seizure susceptibility were evaluated in control animals 3h after alcohol intoxication, as well as 3h (before AWS), 24h (when AWS susceptibility is maximal), and 48h (when AWS susceptibility is no longer present) after alcohol withdrawal. Nifedipine, nimodipine (L-type antagonists) or ω-agatoxin TK (P-type antagonist) were infused intra-IC to probe the role of CaV channels in the pathogenesis of AWS. CaV current density and conductance in IC neurons were significantly increased 3 and 24h after alcohol withdrawal compared with the control group or the group tested 3h following ethanol intoxication. Blockade of L-type CaV channels within the IC completely suppressed AWS, and inhibition of P-type channels reduced AWS severity. These findings suggest that the enhancement of CaV currents in IC neurons occurs prior to AWS onset and that alterations in L- and P-type CaV channels in these neurons may underlie the pathogenesis of AWS.

    Humans diagnosed with alcohol use disorder are more sensitive to painful stimuli during withdrawal, which suggests that excessive alcohol drinking worsens pain outcomes. Alcohol-dependent rats exhibit increases in nociceptive sensitivity during withdrawal. Data from animal models suggest that brain melanocortin-4 receptors (MC4Rs) mediate alcohol drinking and nociception. Here we tested: (1) the effect of alcohol dependence on thermal nociception in rats, and (2) the ability of acute alcohol and (3) MC4R antagonists to reverse hyperalgesia during withdrawal in alcohol-dependent rats. Rats were trained to self-administer operant alcohol and were tested for baseline thermal nociception. Half of the rats were made dependent on alcohol, then all rats were cannulated in the lateral ventricle. We tested the effects of acute alcohol drinking, acute fixed-dose alcohol, intra-ventricular agouti-related protein (endogenous MC4R antagonist), intra-ventricular HS014 (synthetic MC4R antagonist) and intra-nasal HS014 on hyperalgesia during withdrawal in alcohol-dependent rats, relative to non-dependent drinkers and alcohol-naïve controls. Alcohol-dependent rats exhibit thermal hyperalgesia that is abolished by alcohol drinking, bolus alcohol and intra-ventricular and intra-nasal MC4R antagonists. These manipulations did not affect thermal nociception in non-dependent drinkers and alcohol-naïve controls, suggesting that alcohol dependence produces neuroadaptations in brain MC4R systems. These results suggest that brain MC4R systems may be an effective therapeutic target for reducing nociception in the alcohol-dependent organism.

    Negative symptoms (e.g., asociality and anhedonia) are a distinct symptomatic domain that has been found to significantly affect the quality of life in patients diagnosed with schizophrenia. Additionally, the primary negative symptom of asociality (i.e., withdrawal from social contact that derives from indifference or lack of desire to have social contact) is a major contributor to poor psychosocial functioning and has been found to play an important role in the course of the disorder. Nonetheless, the pathophysiology underlying these symptoms is unknown and currently available treatment options (e.g., antipsychotics and cognitive-behavioral therapy) fail to reliably produce efficacious benefits. Utilizing rodent paradigms that measure social behaviors (e.g., social withdrawal) to elucidate the neurobiological substrates that underlie social dysfunction and to identify novel therapeutic targets may be highly informative and useful to understand more about the negative symptoms of schizophrenia. Accordingly, the purpose of this review is to provide an overview of the behavioral tasks for assessing social functioning that may be translationally relevant for investigating negative symptoms associated with schizophrenia.

  7. Excitability of jcBNST neurons is reduced in alcohol-dependent animals during protracted alcohol withdrawal.

    Alcohol dependence and withdrawal has been shown to cause neuroadaptive changes at multiple levels of the nervous system. At the neuron level, adaptations of synaptic connections have been extensively studied in a number of brain areas and accumulating evidence also shows the importance of alcohol dependence-related changes in the intrinsic cellular properties of neurons. At the same time, it is still largely unknown how such neural adaptations impact the firing and integrative properties of neurons. To address these problems, here, we analyze physiological properties of neurons in the bed nucleus of stria terminalis (jcBNST) in animals with a history of alcohol dependence. As a comprehensive approach, first we measure passive and active membrane properties of neurons using conventional current clamp protocols and then analyze their firing responses under the action of simulated synaptic bombardment via dynamic clamp. We find that most physiological properties as measured by DC current injection are barely affected during protracted withdrawal. However, neuronal excitability as measured from firing responses under simulated synaptic inputs with the dynamic clamp is markedly reduced in all 3 types of jcBNST neurons. These results support the importance of studying the effects of alcohol and drugs of abuse on the firing properties of neurons with dynamic clamp protocols designed to bring the neurons into a high conductance state. Since the jcBNST integrates excitatory inputs from the basolateral amygdala (BLA) and cortical inputs from the infralimbic and the insular cortices and in turn is believed to contribute to the inhibitory input to the central nucleus of the amygdala (CeA) the reduced excitability of the jcBNST during protracted withdrawal in alcohol-dependent animals will likely affect ability of the jcBNST to shape the activity and output of the CeA.

    Background Ethanol (EtOH) binge drinking is an increasingly common behavior among teenagers that induces long-lasting neurobehavioral alterations in adulthood. An early history of EtOH abuse during adolescence is highly correlated with cocaine addiction in adulthood. Abstinence of cocaine abuse can cause psychiatric symptoms, such as anxiety, psychosis, depression, and cognitive impairments. This study assessed the consequences of adolescent exposure to EtOH on the behavioral alterations promoted by cocaine withdrawal in adulthood. Methods We pretreated juvenile (34–47 days old) or adult (68–81 days old) mice with EtOH (1.25 g/kg) following a binge-drinking pattern. Then, after a three-week period without drug delivery, they were subjected to a chronic cocaine treatment in adulthood and tested under cocaine withdrawal by the ensuing paradigms: open field, elevated plus maze, prepulse inhibition, tail suspension test, and object recognition. Another set of mice were treated with the same EtOH binge-drinking procedure during adolescence and were tested immediately afterwards under the same behavioral paradigms. Results Adolescent EtOH pretreatment undermined the anxiogenic effects observed after cocaine abstinence, reduced prepulse inhibition, and increased immobility scores in the tail suspension test following cocaine withdrawal. Moreover, the memory deficits evoked by these substances when given separately were enhanced in cocaine-withdrawn mice exposed to EtOH during adolescence. EtOH binge drinking during adolescence also induced anxiety, depressive symptoms, and memory impairments when measured immediately afterwards. In contrast, neither EtOH nor cocaine alone or in combination altered any of these behaviors when given in adulthood. Conclusions EtOH binge drinking induces short- and long-term behavioral alterations and modulates cocaine withdrawal symptoms when given in adolescent mice. PMID:28291777

    Electronic cigarettes (e-cigarettes) are battery operated devices that deliver nicotine via inhaled vapour. Few studies have evaluated acute effects on craving and mood, and none have explored effects on cognition. This study aimed to explore the effects of the White Super e-cigarette on desire to smoke, nicotine withdrawal symptoms, attention and working memory. Eighty-six smokers were randomly allocated to either: 18 mg nicotine e-cigarette (nicotine), 0mg e-cigarette (placebo), or just hold the e-cigarette (just hold) conditions. Participants rated their desire to smoke and withdrawal symptoms at baseline (T1), and five (T2) and twenty (T3) minutes after using the e-cigarette ad libitum for 5 min. A subset of participants completed the Letter Cancellation and Brown-Peterson Working Memory Tasks. After 20 min, compared with the just hold group, desire to smoke and some aspects of nicotine withdrawal were significantly reduced in the nicotine and placebo group; the nicotine e-cigarette was superior to placebo in males but not in females. The nicotine e-cigarette also improved working memory performance compared with placebo at the longer interference intervals. There was no effect of nicotine on Letter Cancellation performance. To conclude, the White Super e-cigarette alleviated desire to smoke and withdrawal symptoms 20 min after use although the nicotine content was more important for males. This study also demonstrated for the first time that the nicotine e-cigarette can enhance working memory performance. Further evaluation of the cognitive effects of the e-cigarette and its efficacy as a cessation tool is merited.

    We designed a study to evaluate the use of benzodiazepines and ethanol in patients being assessed for alcohol withdrawal and compare outcomes between the two agents. This is a retrospective chart review of patients admitted to neurocritical care or neurosurgical services who were at risk for ethanol withdrawal between June 2011 and September 2015. Patients were divided into two groups based on the first medication administered for alcohol withdrawal management, either benzodiazepine (n=50) or enteral ethanol (n=50). The primary endpoint was the maximum change in Clinical Institute Withdrawal Assessment of Alcohol scale (CIWA) score within the first 24hours. Secondary endpoints included maximum and minimum CIWA score in 5days, length of stay, and change in Glasgow Coma Scale. Study groups differed by mortality risk, level of coma at admission, and other clinical characteristics, with the ethanol group appearing less severely ill. There was no significant difference between the two groups in the maximum change in CIWA score at 24hours (-0.97, 95%CI: -3.21 to 1.27, p=0.39). Hospital and intensive care unit length of stay was 6.5 days and 1 day shorter for the ethanol group (p=0.03 and p=0.02, respectively). In summary, enteral ethanol was preferentially used in patients who are more likely to be capable of tolerating oral intake. We found that the change from baseline in CIWA score or other physiologic variables was not substantially different between the two agents. The overall utility of benzodiazepines and enteral ethanol remains unclear for this population and further study is needed to determine superiority.

    Previous studies have suggested that sensory cues associated with cigarette smoking can suppress certain smoking withdrawal symptoms, including craving for cigarettes. In this study we investigated the subjective effects of a cigarette substitute delivering a vapor of black pepper essential oil. Forty-eight cigarette smokers participated in a 3-h session conducted after overnight deprivation from smoking. Subjects were randomly assigned to one of three conditions: one group of smokers puffed on a device that delivered a vapor from essential oil of black pepper; a second group puffed on the device with a mint/menthol cartridge, and a third group used a device containing an empty cartridge. Subjects puffed and inhaled ad libitum from the device throughout the session during which no smoking was allowed. Reported craving for cigarettes was significantly reduced in the pepper condition relative to each of the two control conditions. In addition, negative affect and somatic symptoms of anxiety were alleviated in the pepper condition relative to the unflavored placebo. The intensity of sensations in the chest was also significantly higher for the pepper condition. These results support the view that respiratory tract sensations are important in alleviating smoking withdrawal symptoms. Cigarette substitutes delivering pepper constituents may prove useful in smoking cessation treatment.

    Glial activation is hypothesized to contribute directly to opioid withdrawal. This study investigated the dose-dependent effects of a glial cell modulator, ibudilast, on withdrawal symptoms in opioid-dependent volunteers after abrupt discontinuation of morphine administration. Non-treatment-seeking heroin-dependent volunteers (n = 31) completed the in-patient, double-blind, placebo-controlled, within-subject and between-group study. Volunteers were maintained on morphine (30 mg, QID) for 14 days and placebo (0 mg, QID) for the last 7 days of the 3-week study. Volunteers also received placebo (0 mg, PO, BID) capsules on days 1-7. On days 8-21, volunteers were randomized to receive ibudilast (20 or 40 mg, PO, BID) or placebo capsules. Subjective and clinical ratings of withdrawal symptoms were completed daily using daily using the Subjective Opioid Withdrawal Scale (SOWS) and Clinical Opioid Withdrawal Scale (COWS). Medication side effects were also monitored. Relative to the first 2 weeks, all groups exhibited withdrawal during the third week as assessed by the SOWS and COWS (P ≤ 0.0001). Although overall SOWS scores did not differ between groups, exploratory analyses pooling the two ibudilast groups demonstrated that they had lower ratings of withdrawal symptoms on SOWS items ('anxious,' 'perspiring,' 'restless,' 'stomach cramps') during detoxification relative to the placebo group. Ibudilast was well tolerated; no serious adverse events occurred during the study. Pharmacological modulation of glial activity with ibudilast decreased some subjective ratings of opioid withdrawal symptoms. These exploratory findings are the first to demonstrate the potential clinical utility of glial modulators for treating opioid withdrawal in humans.

    Alcohol misuse and related morbidity continues to represent a challenge to the both the National Health Service (NHS) and the Defence Medical Services (DMS). A significant part of the management of patients who misuse alcohol involves planned assisted withdrawal for dependent drinkers. Traditionally, assisted alcohol withdrawal has been conducted in an in-patient setting owing to the perceived risks of carrying out this treatment. Current evidence shows that community-based approaches offer a safe and effective alternative to the traditional in-patient model with significant cost savings. This article proposes a model for community-assisted alcohol withdrawal (CAAW) for use within the DMS. It considers current guidelines and models already in operation within the NHS, offering evaluation and adjustments to fit the requirements that are applicable to the UK Armed Forces medical environment.

    2012-06-01

    The current investigation explored the main and interactive effects of anxiety sensitivity (AS) and state anxiety in predicting acute nicotine withdrawal symptoms experienced during the initial 14 days of smoking cessation. Participants included 123 adult daily smokers (84 women; Mage = 45.93 years, SD = 10.34) undergoing psychosocial-pharmacological cessation treatment. Results indicated that after controlling for the effects of participant sex and nicotine dependence, state anxiety but not AS significantly predicted initial levels of nicotine withdrawal symptoms. Results also demonstrated that both state anxiety and AS were significantly related to the change in nicotine withdrawal symptoms over time. Finally, our results revealed a significant interaction between AS and state anxiety. Specifically, higher levels of AS were associated with a stronger relation between state anxiety and nicotine withdrawal symptoms experienced during the cessation attempt. Results suggest that among high AS persons, state anxiety may be more relevant, compared to those low in AS, in regard to experiencing withdrawal symptoms as more intense during the early phases of quitting.

    We have previously shown that coadministration of the dopamine (DA) agonist phentermine plus the serotonergic agonist fenfluramine suppresses alcohol intake and withdrawal seizures in rats. In the present study, phentermine and the serotonin (5-HT) precursor, 5-hydroxy-L-tryptophan (5-HTP), were administered alone, or in combination, to rats fed on a 6% alcohol-containing diet or an isocaloric control diet. Following a 9-h withdrawal period from the alcohol-containing diet, phentermine enhanced the effects of 5-HTP on both reduction of alcohol withdrawal seizures as well as changes in striatal serotonin. Food intake was monitored for 24 h after drug treatment, and neurochemical measures were examined at various time points. Phentermine alone reduced food intake in all diet conditions, but this anorectic effect was followed by hyperphagia in control rats. Phentermine plus 5-HTP reduced the consumption of the alcohol-containing diet, while its effects on consumption of control diets were mixed. In vivo microdialysis in rat nucleus accumbens revealed that phentermine increased extracellular DA, whereas 5-HTP caused marked elevations in extracellular 5-HT. Coadministration of phentermine and 5-HTP evoked simultaneous elevations in extracellular DA and 5-HT that mirrored the effects of each drug alone. Collectively, these findings show that coadministered phentermine plus 5-HTP is effective in reducing alcohol intake and suppressing alcohol withdrawal seizures. These therapeutic actions may be related to elevations in synaptic DA and 5-HT in critical brain regions.

    Background. Dextromethorphan is a noncompetitive N-methyl D-aspartate receptor antagonist that is clinically feasible for relieving the opioid withdrawal symptoms. This study compares the efficacy of a combination therapy with dextromethorphan and clonidine to treatment with clonidine alone. Methods and Materials. In this double-blind randomized clinical trial, patients were selected from inpatients of detox and rehabilitation ward of Razi Hospital, Tabriz, Iran. They were randomly allocated to two groups receiving either clonidine (0.4–1.2 mg/day) or clonidine and dextromethorphan (300 mg/day). Withdrawal symptoms were evaluated in the first day of admission and again 24, 48, and 72 hours later. Results. Thirty male patients completed the trial in each group. Withdrawal symptoms began to decrease in the second day in patients receiving dextromethorphan and clonidine while patients receiving clonidine experienced the more severe symptoms in 72 hours. Analysis of variance of the symptom severity score revealed a significant group × time interaction (F = 14.25; P < 0.001), so that patients receiving dextromethorphan plus clonidine had milder symptoms during three days in all of the measurements compared to clonidine group. Conclusion. Combination therapy of dextromethorphan and clonidine would result in milder opioid withdrawal symptoms compared to clonidine alone with a reduction beginning at the second day.

    It is known that the glutamatergic pathways are hyperfunctioning during alcohol withdrawal syndrome. It has been demonstrated that hyperfunctioning of this system causes a great damage to the superior cortical activity, the ability to concentrate and the control of impulses. Recent studies show that the cations zinc and magnesium modulate the glutamatergic function, reducing it to non-toxic levels, yet not reducing it to the point of depriving this neurotransmitter of its normal activity. New perspectives of treatment focus on the modulation of this system, having, as a result, reestablishment of impulse control abilities, damage prevention to the hippocampus and the amygdala and prevention of future relapses.

    Purpose: Benzodiazepines (BDZs) are the drugs of choice to prevent the symptoms of alcohol withdrawal syndrome (AWS). Various treatment protocols are published and have been shown to be effective in both office-managed and facility-managed treatment of AWS. The aim of this scientific commentary is to demonstrate the differences in the expected exposure to BDZs during AWS treatment using different treatment regimens available in the literature, in patients with or without alcoholic liver cirrhosis. Methods: Diazepam and lorazepam AWS protocols were examined and reviewed in the literature, and blood plasma levels were examined and compared, respectively. Results: Considerable variation in the blood levels with the different dosing schedules was found. Because the drugs are metabolized differently, we have also shown that liver disease affects the blood levels of diazepam, but not of lorazepam. Conclusions: Differences in treatment regimens, the choice of BDZ, as well as the presence of liver cirrhosis can substantially alter the exposure of patients to drugs used for AWS treatment. Outpatient treatment of AWS has been shown to be relatively safe and effective for the treatment of AWS but patients should be carefully monitored. PMID:26322116

    Despite years of neurobiological research that have helped to identify potential therapeutic targets, we do not have a reliable pharmacological treatment for alcoholism. There are a range of possible explanations for this failure, including arguments that alcoholism is a spectrum disorder and that different population subtypes may respond to different treatments. This view is supported by categorisations such as early- and late-onset alcoholism, whilst multifactorial genetic factors may also alter responsivity to pharmacological agents. Furthermore, experience of alcohol withdrawal may play a role in future drinking in a way that may distinguish alcoholism from other forms of addiction. Additionally, our neurobiological models, based largely upon results from rodent studies, may not mimic specific aspects of the human condition and may reflect different underlying phenomena and biological processes from the clinical pattern. As a result, potential treatments may be targeting inappropriate aspects of alcohol-related behaviours. Instead, we suggest a more profitable approach is (a) to identify well-defined intermediate behavioural phenotypes in human experimental models that reflect defined aspects of the human clinical disorder and (b) to develop animal models that are homologous with those phenotypes in terms of psychological processes and underlying neurobiological mechanisms. This review describes an array of animal models currently used in the addiction field and what they tell us about alcoholism. We will then examine how established pharmacological agents have been developed using only a limited number of these models, before describing some alternative novel approaches to achieving homology between animal and human experimental measures.

    This paper examined whether adult children of alcoholics (ACOAs) would report more depressive mood symptoms as compared to non-ACOAs, whether coping behaviors differed as a function of ACOA status, and whether specific coping behaviors were related to depressive mood symptoms in ACOAs. Participants were 136 college students categorized as ACOAs and 436 college students categorized as non-ACOAs as determined by scores on the Children of Alcoholics Screening Test (CAST; J.W.Jones, 1983 The children of alcoholics screening test: test manual. Chicago: Camelot). As compared to non-ACOAs, ACOAs reported significantly more symptoms of depressive mood as measured by the Profile of Mood States (POMS; McNair, Lorr, and Droppleman, 1992 POMS manual: profile of mood states. San Diego, CA: Edits). On the COPE Inventory (Carver, Scheier, and Weintraub, 1989 Assessing coping strategies: a theoretically based approach. Journal of Personality and Social Psychology, 56:267-283), ACOAs reported higher use of the following coping strategies: Behavior Disengagement, Denial, Focus on and Venting of Emotions, Humor, and Substance Use. For both the ACOA and non-ACOA groups, the use of Positive Reinterpretation and Growth and the use of Planning were significantly associated with fewer depressive symptoms, whereas Mental Disengagement, Focus on and Venting of Emotions, Denial, Behavior Disengagement, Substance Use, and Suppression of Competing Activities were associated with higher depressive mood scores.

    Introduction: Virtual reality (VR) has been shown to be effective in eliciting responses to nicotine cues in cigarette smokers. The primary aim of this study was to investigate whether cigarette-deprived smokers would exhibit increased craving and changes in heart rate when viewing cigarette related cues as compared to non-smoking cues in a VR environment, and the secondary aim was to assess the extent to which self-assessed measures of withdrawal and dependence correlated with VR craving. Methods: Nicotine-dependent cigarette smokers were recruited for a 2 day study. On Day 1, participants smoked as usual and on Day 2 were deprived from smoking overnight. On both days, participants completed self-assessment questionnaires on withdrawal, craving, and nicotine-dependence. Participants completed a VR session during the cigarette deprivation condition only (Day 2). During this session, they were exposed to active smoking and placebo (non-smoking) cues. Results: The data show that self-reported levels of “craving” (p < .01) and “thinking about cigarettes” (p < .0001) were significantly greater after exposure to the active cues versus non-smoking cues. Significant increases in heart rate were found for 3 of 4 active cues when compared to non-smoking cues (p < .05). Finally, significant positive correlations were found between self-reported craving prior to the VR session and craving induced by active VR cues (p < .01). Conclusions: In this report, active VR cues elicited craving during cigarette deprivation. This is the first study to demonstrate that self-reported craving, withdrawal symptoms, and nicotine dependence severity predict cue-induced craving in the VR setting. PMID:25475087

    Separate and combined effects of nicotine and the nicotinic antagonist mecamylamine were studied in 32 healthy volunteer smokers after overnight abstinence from smoking. Subjects participated in three sessions (3 h each), during which they wore skin patches delivering either 0 mg/24 h, 21 mg/24 h or 42 mg/24 h nicotine. Thirty-two subjects were randomly assigned to two groups receiving oral mecamylamine hydrochloride (10 mg) vs. placebo capsules. Two and one-half hours after drug administration, subjects were allowed to smoke ad lib, rating the cigarettes for rewarding and aversive effects. Transdermal nicotine produced a dose-related reduction in the subjective rewarding qualities of smoking. Nicotine also reduced craving for cigarettes and this effect was attenuated, but not eliminated, by mecamylamine. Mecamylamine blocked the discriminability of high vs. low nicotine puffs of smoke, and increased nicotine intake substantially during the ad lib smoking period. Some of the psychophysiological effects of each drug (elevation in blood pressure from nicotine, sedation and decreased blood pressure from mecamylamine) were offset by the other drug. The results supported the hypothesis that nicotine replacement can alleviate tobacco withdrawal symptoms even in the presence of an antagonist such as mecamylamine. Mecamylamine did not precipitate withdrawal beyond the level associated with overnight cigarette deprivation, suggesting its effects were primarily due to offsetting the action of concurrently administered nicotine as opposed to blocking endogenous cholinergic transmission.

    Exposure to smoking cues increases craving for cigarettes and can precipitate relapse. Whereas brain imaging studies have identified a distinct network of brain regions subserving the processing of smoking cues, little is known about the influence of individual difference factors and withdrawal symptoms on brain cue reactivity. Multiple regression analysis was used to evaluate relations between individual difference factors and withdrawal symptoms and event-related blood oxygen level-dependent responses to visual smoking cues in a sample of 30 smokers. Predictors were self-report nicotine dependence (Fagerström test of nicotine dependence, FTND), prescan withdrawal symptoms (craving and negative affect), and sex. The unique variance of each predictor was examined after controlling for each of the others. Positive associations were observed between FTND and reactivity to cues in right anterior cingulate and orbitofrontal cortex (OFC) whereas negative associations were observed between prescan craving and reactivity in ventral striatum. Higher negative affect or being male was associated with greater reactivity in left hippocampus and left OFC. Women exhibited greater cue reactivity than men in regions including the cuneus and left superior temporal gyrus. Individual difference factors and withdrawal symptoms were uniquely associated with brain reactivity to smoking cues in regions subserving reward, affect, attention, motivation, and memory. These findings provide further evidence that reactivity to conditioned drug cues is multiply determined and suggest that smoking cessation treatments designed to reduce cue reactivity focus on each of these variables.

    Cessation of chronic ethanol consumption can increase the sensitivity of the brain to excitotoxic damages. Cannabinoids have been proposed as neuroprotectants in different models of neuronal injury, but their effect have never been investigated in a context of excitotoxicity after alcohol cessation. Here we examined the effects of the pharmacological activation/inhibition of the endocannabinoid system in an in vitro model of chronic ethanol exposure and withdrawal followed by an excitotoxic challenge. Ethanol withdrawal increased N-methyl-D-aspartate (NMDA)-evoked neuronal death, probably by altering the ratio between GluN2A and GluN2B NMDA receptor subunits. The stimulation of the endocannabinoid system with the cannabinoid agonist HU-210 decreased NMDA-induced neuronal death exclusively in ethanol-withdrawn neurons. This neuroprotection could be explained by a decrease in NMDA-stimulated calcium influx after the administration of HU-210, found exclusively in ethanol-withdrawn neurons. By contrast, the inhibition of the cannabinoid system with the CB1 receptor antagonist rimonabant (SR141716) during ethanol withdrawal increased death of ethanol-withdrawn neurons without any modification of NMDA-stimulated calcium influx. Moreover, chronic administration of rimonabant increased NMDA-stimulated toxicity not only in withdrawn neurons, but also in control neurons. In summary, we show for the first time that the stimulation of the endocannabinoid system is protective against the hyperexcitability developed during alcohol withdrawal. By contrast, the blockade of the endocannabinoid system is highly counterproductive during alcohol withdrawal.

    Neuropeptide Y (NPY)- and acetylcholine-containing interneurons of the nucleus accumbens (NAc) seem to play a major role in the rewarding effects of alcohol. This study investigated the relationship between chronic alcohol consumption and subsequent withdrawal and the expression of NPY and acetylcholine in the NAc, and the possible involvement of nerve growth factor (NGF) in mediating the effects of ethanol. Rats ingesting an aqueous ethanol solution over 6months and rats subsequently deprived from ethanol during 2months were used to estimate the total number and the somatic volume of NPY and cholinergic interneurons, and the numerical density of cholinergic varicosities in the NAc. The tissue content of choline acetyltransferase (ChAT) and catecholamines were also determined. The number of NPY interneurons increased during alcohol ingestion and returned to control values after withdrawal. Conversely, the number and the size of cholinergic interneurons, and the amount of ChAT were unchanged in ethanol-treated and withdrawn rats, but the density of cholinergic varicosities was reduced by 50% during alcohol consumption and by 64% after withdrawal. The concentrations of dopamine and norepinephrine were unchanged both during alcohol consumption and after withdrawal. The administration of NGF to withdrawn rats significantly increased the number of NPY-immunoreactive neurons, the size of cholinergic neurons and the density of cholinergic varicosities. Present data show that chronic alcohol consumption leads to long-lasting neuroadaptive changes of the cholinergic innervation of the NAc and suggest that the cholinergic system is a potential target for the development of therapeutic strategies in alcoholism and abstinence.

    Alcohol use disorders (AUDs) are associated with functional and morphological changes in subfields of the prefrontal cortex. Clinical and preclinical evidence indicates that the orbitofrontal cortex (OFC) is critical for controlling impulsive behaviors, representing the value of a predicted outcome, and reversing learned associations. Individuals with AUDs often demonstrate deficits in OFC-dependent tasks, and rodent models of alcohol exposure show that OFC-dependent behaviors are impaired by chronic alcohol exposure. To explore the mechanisms that underlie these impairments, we examined dendritic spine density and morphology, and NMDA-type glutamate receptor expression in the lateral OFC of C57BL/6J mice following chronic intermittent ethanol (CIE) exposure. Western blot analysis demonstrated that NMDA receptors were not altered immediately following CIE exposure or after 7 days of withdrawal. Morphological analysis of basal dendrites of layer II/III pyramidal neurons revealed that dendritic spine density was also not affected immediately after CIE exposure. However, the total density of dendritic spines was significantly increased after a 7-day withdrawal from CIE exposure. The effect of withdrawal on spine density was mediated by an increase in the density of long, thin spines with no change in either stubby or mushroom spines. These data suggest that morphological neuroadaptations in lateral OFC neurons develop during alcohol withdrawal and occur in the absence of changes in the expression of NMDA-type glutamate receptors. The enhanced spine density that follows alcohol withdrawal may contribute to the impairments in OFC-dependent behaviors observed in CIE-treated mice.

    A growing number of laboratory studies have shown that acute bouts of aerobic exercise favorably impact affect and cravings among smokers. However, randomized trials have generally shown exercise to have no favorable effect on smoking cessation or withdrawal symptoms during quit attempts. The purpose of the present study was to explore this apparent contradiction by assessing acute changes in affect and cravings immediately prior to and following each exercise and contact control session during an eight-week smoking cessation trial. Sixty previously low-active, healthy, female smokers were randomized to an eight-week program consisting of brief baseline smoking cessation counseling and the nicotine patch plus either three sessions/week of moderate intensity aerobic exercise or contact control. Findings revealed a favorable impact of exercise on acute changes in positive activated affect (i.e., energy), negative deactivated affect (i.e., tiredness), and cigarette cravings relative to contact control. However, effects dissipated from session to session. Results suggest that aerobic exercise has potential as a smoking cessation treatment, but that it must be engaged in frequently and consistently over time in order to derive benefits. Thus, it is not surprising that previous randomized controlled trials-in which adherence to exercise programs has generally been poor-have been unsuccessful in showing effects of aerobic exercise on smoking cessation outcomes.

    Mental health is likely to be influenced by contextual variables that emerge only at the level of the group. We studied the effect of two such group-level variables, within-state income inequality and alcohol tax policy, on symptoms of current depression and alcohol dependence in a US national sample, controlling for state-level and individual characteristics. A cross-sectional US national probability sample provided the individual-level data. State income data were obtained from the 1990 US census. The Gini coefficient (raw and adjusted) indicated income inequality. Outcome measures included current symptoms of depression and alcohol dependence. Controlling for individual-level variables and state median income, the odds of depressive symptoms was not positively associated with state income inequality. Controlling for individual-level variables, state median income and alcohol distribution method, a weak negative association between Gini and alcohol dependence was observed in women, but this association disappeared after additional adjustment for beer tax. No association was observed in men. Higher state beer tax was significantly associated with lower prevalence of alcohol dependence symptoms for both men and women. The results suggest that state income inequality does not increase the experience of alcohol dependence or depression symptoms. However, evidence was found for a protective effect of increased beer taxation against alcohol dependence symptoms, suggesting the need to further consider the impact of alcohol policies on alcohol use disorders.

    Both alcohol withdrawal syndrome (AWS) and benzodiazepines can cause delirium. Benzodiazepine-associated delirium can complicate AWS and prolong hospitalization. Benzodiazepine delirium can be diagnosed with flumazenil, a GABA-A receptor antagonist. By reversing the effects of benzodiazepines, flumazenil is theorized to exacerbate symptoms of AWS and precludes its use. For patients being treated for alcohol withdrawal, flumazenil can diagnose and treat benzodiazepine delirium without precipitating serious or life-threatening adverse events. Hospital admission records were retrospectively reviewed for patients with the diagnosis of AWS who received both benzodiazepines and flumazenil from December 2006 to June 2012 at a university-affiliated inpatient toxicology center. The day of last alcohol consumption was estimated from available blood alcohol content or subjective history. Corresponding benzodiazepine, flumazenil, and adjunctive sedative pharmacy records were reviewed, as were demographic, clinical course, and outcome data. Eighty-five patients were identified (average age 50.3 years). Alcohol concentrations were detectable for 42 patients with average 261 mg/dL (10-530 mg/dL). Eighty patients were treated with adjunctive agents for alcohol withdrawal including antipsychotics (n = 57), opioids (n = 27), clonidine (n = 35), and phenobarbital (n = 23). Average time of flumazenil administration was 4.7 days (1-11 days) after abstinence, and average dose was 0.5 mg (0.2-1 mg). At the time of flumazenil administration, delirium was described as hypoactive (n = 21), hyperactive (n = 15), mixed (n = 41), or not specified (n = 8). Response was not documented in 11 cases. Sixty-two (72.9 %) patients had significant objective improvement after receiving flumazenil. Fifty-six patients required more than one dose (average 5.6 doses). There were no major adverse events and minor adverse effects included transiently increased anxiety

    To determine fetal growth and the incidence of withdrawal symptoms in term infants exposed to methamphetamine in utero, we retrospectively identified neonates whose mothers used methamphetamine during pregnancy and matched them to unexposed newborns. Exclusion criteria included multiple and preterm gestations. Although there were no differences in infant growth parameters between the methamphetamine-exposed and methamphetamine-unexposed neonates, methamphetamine exposure throughout gestation was associated with decreased growth relative to infants exposed only for the first two trimesters. In addition, there were significantly more small for gestational age infants in the methamphetamine group compared with the unexposed group. Methamphetamine-exposed infants whose mothers smoked had significantly decreased growth relative to infants exposed to methamphetamine alone. Withdrawal symptoms (as determined by a previously reported scoring system) requiring pharmacologic intervention were observed in 4% of methamphetamine-exposed infants. These preliminary findings indicate that methamphetamine use is associated with growth restriction in infants born at term.

    Dexmedetomidine is currently used in the US in the treatment of alcohol withdrawal syndrome (AWS) in the intensive care unit (ICU) setting, although data to support this practice are limited. Dexmedetomidine targets the noradrenergic system, an important but frequently overlooked secondary mechanism in the development of AWS, and, in doing so, may reduce the need for excessive benzodiazepine use which can increase the risk of γ-aminobutyric acid (GABA)-mediated deliriogenesis and respiratory depression. The purpose of this narrative review is to evaluate available literature reporting on the safety and efficacy of dexmedetomidine for AWS in the ICU setting. An English-language MEDLINE search (1966 to July 2013) was performed to identify articles evaluating the efficacy and safety of dexmedetomidine for AWS. Case series, case reports and controlled trials were evaluated for topic relevance and clinical applicability. Reference lists of articles retrieved through this search were reviewed to identify any relevant publications. Studies focusing on the safety and efficacy of dexmedetomidine for AWS in humans were selected. Studies were included if they were published as full articles; abstracts alone were not included in this review. Eight published case studies and case series were identified. Based on a limited body of evidence, dexmedetomidine shows promise as a potentially safe and possibly effective adjuvant treatment for AWS in the ICU. Prospective, well-controlled studies are needed to confirm the safety and efficacy of the use of dexmedetomidine in AWS.

    The relationship between anxiety and alcohol use in adolescence remains unclear, with evidence for no association and for risk and protective effects of anxiety. Considering developmental trajectories may be important for understanding the association between anxiety and alcohol use and may help clarify prior mixed findings. The present study examined trajectories of alcohol use, social anxiety symptoms, and general anxiety symptoms in early to middle adolescence through the use of univariate and parallel process growth models. Social anxiety and general anxiety symptoms declined, while alcohol use increased with age. Parallel process growth models suggested that less rapid declines in social anxiety and general anxiety symptoms were associated with more rapid escalation in alcohol use. These results suggest that young adolescents who do not show normative declines in social anxiety or general anxiety symptoms may be at risk for more rapid increases in alcohol use.

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

    2005-12-14

    Repeated cycles of chronic ethanol exposure and withdrawal result in sensitization of withdrawal-related CNS hyperexcitability that generally reflects an imbalance in activity of GABA and glutamate systems. Many pharmacological treatments for ethanol withdrawal target neuroadaptive changes in GABA and glutamate neurotransmission. The present study utilized a mouse model of repeated withdrawals to evaluate the ability of lorazepam and MK-801 treatments to antagonize behavioral and electroencephalographic (EEG) measures of sensitized withdrawal seizure activity. Adult male C3H/He mice received chronic intermittent ethanol vapor exposure in inhalation chambers (16 h/day) and during each withdrawal cycle, separate groups of mice were evaluated for handling-induced convulsions (HIC) or abnormal EEG (high-voltage "brief spindle episodes" (BSE)) activity. Lorazepam (0.5-1.0 mg/kg) or MK-801 (0.1-0.3 mg/kg) treatment at 1 h into each of three withdrawal cycles reduced behavioral (HIC) and electrographic (BSE) signs of seizure activity in a dose-related fashion compared to vehicle-treated mice. During a subsequent untreated withdrawal, mice previously treated with lorazepam or MK-801 for earlier withdrawals exhibited reduced HIC activity during the acute phase but exacerbated HIC activity during the protracted phase of this final (fourth) withdrawal cycle. Both lorazepam and MK-801 treatment conditions resulted in enhanced BSE activity during the entire fourth (untreated) withdrawal episode. Collectively, these results suggest that while treatment of repeated ethanol withdrawals with a benzodiazepine (lorazepam) or an NMDA receptor antagonist (MK-801) may have some initial benefits in ameliorating the development of sensitized withdrawal excitability, such treatment may also render subjects more vulnerable to seizure activity at later time points.

    Background Smokeless, spitless tobacco products are being introduced and marketed as cigarette substitutes. Data are needed regarding how smokers interested in cessation would use these products, the levels of resultant toxicant exposure and the feasibility of using these products as aids for tobacco cessation. Methods Smokers were randomized to receive Camel Snus (n=51), Taboka (n=52) or medicinal nicotine (n=27) and required to quit smoking for 4 weeks. Measures of toxicant exposure and symptoms of craving and withdrawal were assessed prior to and during product use. Results Concentrations of exhaled carbon monoxide, urinary cotinine, urinary total NNAL and urinary total NNN were significantly (p values <0.05) lower at the end of treatment in each group except for total NNN in those receiving Camel Snus (p=0.066). A significant group × time effect was observed for total NNAL concentrations (p=0.002) with the decrease greatest in the medicinal nicotine group and smallest decrease in the Camel Snus group. No significant differences between groups were found in craving and withdrawal symptoms. Conclusions Enrolling smokers into a cessation study utilizing newer smokeless tobacco products is feasible. Camel Snus and Taboka use was not found to be superior to medicinal nicotine in reducing withdrawal symptoms but decreases in NNAL were smaller in users of Camel Snus.

    Excess activation of glutamatergic neurotransmission in the cerebral cortex following ethanol withdrawal is considered to contribute to significant behavioural disturbances, and to alcohol craving. Astrocytes may play a role in these manifestations because astrocytes are essential in the regulation of released glutamate and its conversion to glutamine through the enzyme glutamine synthetase (GS). However, it is unclear if withdrawal from free-choice ethanol drinking causes changes in the numbers of astrocytes expressing GS or the cytoskeletal protein of astrocytes glial fibrillary acidic protein (GFAP). Alcohol-preferring (P) rats exposed to free-choice ethanol drinking were either maintained without forced interruption of ethanol drinking, subjected to a 3-day withdrawal period at the end of 2 months, or subjected to three 3-day withdrawal periods along 6 months. At 2 months, P rats were also compared with alcohol-naïve alcohol non-preferring rats (NP) rats. Packing density of GS and GFAP-immunoreactive (IR) astrocytes was measured in sections from the prelimbic cortex (PLC) using the optical disector probe. An alcohol deprivation effect was observed in P rats with withdrawals during a 6-month ethanol drinking period. Ethanol withdrawal significantly increased the packing density of GS- and GFAP-IR astrocytes in the PLC of P rats as compared with P rats with continuous access to ethanol. In addition, there was a positive correlation between the pre-withdrawal ethanol consumption and the packing density of GS-IR astrocytes. The present results suggest the involvement of astrocytes in the regulation of the glutamatergic activation associated with withdrawal from free-choice ethanol consumption and point to differential adaptations of GS and GFAP to prolonged alcohol drinking in the PLC of P rats.

    Aims: The aim of this study was to examine alcohol abuse/dependence symptoms among hospital employees exposed to a severe acute respiratory syndrome (SARS) outbreak, and the relationship between types of exposure to the SARS outbreak and subsequent alcohol abuse/dependence symptoms. Methods: A survey was conducted among 549 randomly selected hospital employees in Beijing, China, concerning the psychological impact of the 2003 SARS outbreak. Subjects were assessed on sociodemographic factors and types of exposure to the outbreak, and on symptoms of post-traumatic stress (PTS), alcohol abuse/dependence and depression. Results: Current alcohol abuse/dependence symptom counts 3 years after the outbreak were positively associated with having been quarantined, or worked in high-risk locations such as SARS wards, during the outbreak. However, having had family members or friends contract, SARS was not related to alcohol abuse/dependence symptom count. Symptoms of PTS and of depression, and having used drinking as a coping method, were also significantly associated with increased alcohol abuse/dependence symptoms. The relationship between outbreak exposure and alcohol abuse/dependence symptom count remained significant even when sociodemographic and other factors were controlled for. When the intrusion, avoidance and hyperarousal PTS symptom clusters were entered into the model, hyperarousal was found to be significantly associated with alcohol abuse/dependence symptoms. Conclusions: Exposure to an outbreak of a severe infectious disease can, like other disaster exposures, lead not only to PTSD but also to other psychiatric conditions, such as alcohol abuse/dependence. The findings will help policy makers and health professionals to better prepare for potential outbreaks of diseases such as SARS or avian flu. PMID:18790829

    With the widespread use of atypical or second-generation antipsychotics, switching treatment has become current practice and more complicated, as the pharmacological profiles of these agents differ substantially despite their similarity in being 'atypical'. All share the ability to block dopamine D₂ receptors, and most of them also block serotonin 5-HT2A receptors. Apart from these common features, some atypical antipsychotics are also able to block or stimulate other dopamine or serotonin receptors, as well as histaminergic, muscarinergic or adrenergic receptors. As a result of the varying receptor affinities, in switching or discontinuing compounds several possible pitfalls have to be considered, including the occurrence of withdrawal and rebound syndromes. This article reviews the pharmacological background of functional blockade or stimulation of receptors of interest in regard to atypical antipsychotics and the implicated potential withdrawal and rebound phenomena. A MEDLINE search was carried out to identify information on withdrawal or rebound syndromes occurring after discontinuation of atypical antipsychotics. Using the resulting literature, we first discuss the theoretical background to the functional consequences of atypical antipsychotic-induced blockade or stimulation of neurotransmitter receptors and, secondly, we highlight the clinical consequences of this. We then review the available clinical literature on switching between atypical antipsychotics, with respect to the occurrence of withdrawal or rebound symptoms. Finally, we offer practical recommendations based on the reviewed findings. The systematic evaluation of withdrawal or rebound phenomena using randomized controlled trials is still understudied. Knowledge of pharmacological receptor-binding profiles may help clinicians in choosing adequate switching or discontinuation strategies for each agent. Results from large switching trials indicate that switching atypical antipsychotics can be

    Although previous studies show that children of alcoholic parents have higher rates of externalizing symptoms compared to their peers, it remains unclear whether the timing of children's externalizing symptoms is linked to that of their parent's alcohol-related symptoms. Using a multilevel modeling approach, we tested whether children aged 2 through 17 showed elevated mother-, father- and child-reported externalizing symptoms (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the study period (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the study period (distal effects). We used integrative data analysis to combine samples from two prospective studies to test these hypotheses. Distal effects of parent alcoholism on increased child externalizing symptoms were large and consistent. In addition, proximal and time-varying effects of parent alcohol symptoms were also found. Implications for preventing escalations in externalizing symptoms among this high-risk population are discussed.

    Striatal-enriched protein tyrosine phosphatase (STEP) is abundantly expressed in the striatum, which strongly expresses dopamine and opioid receptors and mediates the effects of many drugs of abuse. However, little is known about the role of STEP in opioid receptor function. In the present study, we generated STEP-targeted mice carrying a nonsense mutation (C230X) in the kinase interaction domain of STEP by screening the N-ethyl-N-nitrosourea (ENU)-driven mutant mouse genomic DNA library and subsequent in vitro fertilization. It was confirmed that the C230X nonsense mutation completely abolished functional STEP protein expression in the brain. STEPC230X−/− mice showed attenuated acute morphine-induced psychomotor activity and withdrawal symptoms, whereas morphine-induced analgesia, tolerance and reward behaviors were unaffected. STEPC230X−/− mice displayed reduced hyperlocomotion in response to intrastriatal injection of the μ-opioid receptor agonist DAMGO, but the behavioral responses to δ- and κ-opioid receptor agonists remained intact. These results suggest that STEP has a key role in the regulation of psychomotor action and physical dependency to morphine. These data suggest that STEP inhibition may be a critical target for the treatment of withdrawal symptoms associated with morphine. PMID:26915673

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

    Alcohol and nicotine are often used together, and there is a high rate of co-occurrence between alcohol and nicotine addiction. Most animal models studying alcohol and nicotine interactions have utilized passive drug administration, which may not be relevant to human co-addiction. In addition, the interactions between alcohol and nicotine in female animals have been understudied, as most studies have used male animals. To address these issues, we developed models of alcohol and nicotine co-consumption in male and female mice that utilized voluntary, oral consumption of unsweetened alcohol, nicotine and water. We first examined drug consumption and preference in single-drug, sequential alcohol and nicotine consumption tests in male and female C57BL/6 and DBA/2J mice. We then tested chronic continuous and intermittent access alcohol and nicotine co-consumption procedures. We found that male and female C57BL/6 mice readily co-consumed unsweetened alcohol and nicotine. In our continuous co-consumption procedures, we found that varying the available nicotine concentration during an alcohol abstinence period affected compensatory nicotine consumption during alcohol abstinence, and affected rebound alcohol consumption when alcohol was re-introduced. Consumption of alcohol and nicotine in an intermittent co-consumption procedure produced higher alcohol consumption levels, but not nicotine consumption levels, compared with the continuous co-consumption procedures. Finally, we found that intermittent alcohol and nicotine co-consumption resulted in physical dependence. Our data show that these voluntary co-consumption procedures can be easily performed in mice and can be used to study behavioral interactions between alcohol and nicotine consumption, which may better model human alcohol and nicotine co-addiction.

    The current investigation explored the main and interactive effects of panic attacks in response to laboratory-induced bodily sensations and anxiety sensitivity in predicting acute nicotine withdrawal symptoms among daily smokers making a self-guided quit attempt. Participants were 99 daily smokers (58% women; M(age) = 28.4 years, SD = 11.7) who completed a battery of questionnaires, a voluntary hyperventilation challenge, and a measure of nicotine withdrawal symptoms 12 hr after making a self-guided quit attempt. Results indicated that the interaction of anxiety sensitivity and panic responsivity to the challenge predicted quit-day nicotine withdrawal symptom severity above and beyond the main effects (p < .05). The form of the interaction indicated that the relationship between postchallenge panic attack status and acute nicotine withdrawal was more robust among individuals who were low in anxiety sensitivity. Individuals who did not experience a panic attack posthyperventilation who were also low in anxiety sensitivity reported the lowest levels of nicotine withdrawal. Results suggest that anxiety sensitivity may be less relevant with regard to acute nicotine withdrawal severity among individuals with panic-related problems.

    Background Adenosine is involved in several neurological and behavioral disorders including alcoholism. In cultured cell and animal studies, type 1 equilibrative nucleoside transporter (ENT1, slc29a1), which regulates adenosine levels, is known to regulate ethanol sensitivity and preference. Interestingly, in humans, the ENT1 (SLC29A1) gene contains a non-synonymous single nucleotide polymorphism (647 T/C; rs45573936) that might be involved in the functional change of ENT1. Principal Findings Our functional analysis showed that prolonged ethanol exposure increased adenosine uptake activity of mutant cells (ENT1-216Thr) compared to wild-type (ENT1-216Ile) transfected cells, which might result in reduced extracellular adenosine levels. We found that mice lacking ENT1 displayed increased propensity to ethanol withdrawal seizures compared to wild-type littermates. We further investigated a possible association of the 647C variant with alcoholism and the history of alcohol withdrawal seizures in subjects of European ancestry recruited from two independent sites. Analyses of the combined data set showed an association of the 647C variant and alcohol dependence with withdrawal seizures at the nominally significant level. Conclusions Together with the functional data, our findings suggest a potential contribution of a genetic variant of ENT1 to the development of alcoholism with increased risk of alcohol withdrawal-induced seizures in humans.

    Alcohol withdrawal and therapies may affect nerve growth factor (NGF), brain-derived neurotrophic growth factor (BDNF), glial-derived neurotrophic growth factor (GDNF), and epinephrine (EPI). This study evaluated dexmedetomidine (DEX) on NGF, BDNF, GDNF, and EPI in severe alcohol withdrawal and related their plasma concentrations to DEX concentrations. Twenty-four subjects were randomized to DEX 1.2 mcg/kg/hour (high dose [HD]), 0.4 mcg/kg/hour (low dose [LD]), or placebo. Blood was collected at 0 (T0), 48 (T48), and 96-120 (T96) hours after starting the study drug, and concentrations of these transmitters and DEX were determined. Similar NGF suppression occurred at T48 and T96 across all groups. BDNF and GDNF levels increased insignificantly at T48 in the placebo group but steadily declined in both DEX groups, with a trend toward significance in the HD group at T48. EPI concentrations declined significantly in the HD group at T48, only to increase at T96. Median DEX concentrations during the study were insignificantly higher in HD than LD. T0 values of BDNF (r = -0.47, p = 0.02) and GDNF (r = -0.37, p = 0.05) were inversely associated with the need for mechanical ventilation before study enrollment. No other clinical parameter was associated with the plasma concentrations of these transmitters. Daily lorazepam requirements were associated with the severity of withdrawal (r = 0.7, p < 0.0001) and DEX concentrations were inversely related to daily lorazepam requirements (r = -0.33, p = 0.008). DEX utilization suppressed EPI (r = -0.57, p = 0.004). EPI concentrations were associated with BDNF values at T0 (r = 0.55, p = 0.04) and throughout the study (r = 0.25, p = 0.04). In summary, the plasma concentrations of NGF, BDNF, GDNF, and EPI during alcohol withdrawal are variable and the effects of DEX were marginal. DEX administration and higher DEX concentrations attenuated lorazepam administration in the short-term and suppressed EPI.

    Problematic alcohol use has been shown to negatively impact cognitive functions germane to achieving optimal HIV health outcomes. The present study, a secondary data analysis, examined the impact of problematic alcohol use on aspects of everyday memory functioning in a sample of 172 HIV-infected individuals (22 % female; Mage = 48.37 years, SD = 8.64; 39 % Black/non-Hispanic). Additionally, we tested whether self-reported memory functioning explained the relation between problematic alcohol use and HIV symptom severity. Results indicated that problematic patterns of alcohol use were associated with lower total memory functioning, retrieval (e.g., recall-difficulty) and memory for activity (e.g., what you did yesterday) and greater HIV symptom severity. Memory functioning mediated the relation between problematic alcohol use and HIV symptom severity. However, the direction of this relation was unclear as HIV symptom severity also mediated the relation between problematic alcohol use and memory functioning. Findings highlight the importance of integrated care for HIV and alcohol use disorders and suggest that routine alcohol and cognitive screenings may bolster health outcomes among this vulnerable population.

    Objective The purpose of this study was to examine how emotion dysregulation (ED) might help explain the relationship between posttraumatic stress disorder (PTSD) and alcohol dependence (AD) symptoms in females. Method Participants included 260 women from primary, diabetes, and gynecological clinics of an urban public hospital. This is a primarily African American sample (96.9%), including individuals reporting exposure to at least 1 traumatic event. We examined the associations and predictability patterns between severity of PTSD symptoms, ED, and AD symptoms. Results Using linear regression analyses, PTSD avoidance and numbing symptoms and ED were significant predictors of AD symptoms. When looking at specific dimensions of ED, one's inability to engage in goal‐directed behavior under strong emotional influences showed a full indirect effect on the relationship between PTSD avoidance and numbing symptoms and AD symptoms. Conclusion Our findings suggest that having poor emotion regulation skills may help explain why females with PTSD become dependent on alcohol. PMID:27467499

    Alcoholism, HIV, and depressive symptoms frequently co-occur and are associated with impairment in cognition and life function. We administered the Beck Depression Inventory-II (BDI-II), measures of life function, and neurocognitive tests to 67 alcoholics, 56 HIV+ patients, 63 HIV+ alcoholics, and 64 controls to examine whether current depressive symptom level (significant, BDI-II>14 vs. minimal, BDI-II<14) was associated with poorer cognitive or psychosocial function in alcoholism-HIV comorbidity. Participants with significant depressive symptoms demonstrated slower manual motor speed and poorer visuospatial memory than those with minimal depressive symptoms. HIV patients with depressive symptoms showed impaired manual motor speed. Alcoholics with depressive symptoms showed impaired visuospatial memory. HIV+ alcoholics with depressive symptoms reported the poorest quality of life; alcoholics with depressive symptoms, irrespective of HIV status, had poorest life functioning. Thus, significant depressive symptoms were associated with poorer selective cognitive and life functioning in alcoholism and in HIV infection, even though depressive symptoms had neither synergistic nor additive effects on cognition in alcoholism-HIV comorbidity. The results suggest the relevance of assessing and treating current depressive symptoms to reduce cognitive compromise and functional disability in HIV infection, alcoholism, and their comorbidity.

    The study evaluated how spiritual and religious functioning (SRF), alcohol-related problems, and psychiatric symptoms change over the course of treatment and follow-up. Problem drinkers (n = 55, including 39 males and 16 females) in outpatient treatment were administered questionnaires at pretreatment, post-treatment, and follow up, which assessed two aspects of SRF (religious well-being and existential well-being), two aspects of alcohol misuse (severity and consequences), and two aspects of psychiatric symptoms (depression and anxiety). Significant improvements in SRF, psychiatric symptoms and alcohol misuse were observed from pretreatment to follow-up. Although SRF scores were significantly correlated with psychiatric symptoms at all three time points, improvement in the former did not predict improvement in the latter. When measured at the same time points, SRF scores were not correlated with the measures of alcohol misuse. However, improvement in SRF (specifically in existential well-being) over the course of treatment was predictive of improvement in the alcohol misuse measures at follow-up. These results suggest that the association between SRF, emotional problems, and alcohol misuse is complex. They further suggest that patients who improve spiritual functioning over the course of treatment are more likely to experience improvement in drinking behavior and alcohol-related problems after treatment has ended.

    Hazardous alcohol consumption among medical students appears to occur at a level comparable to the general population; however, among medical students, it has been found that the motivation to use alcohol partially stems from unique stressors related to their professional training. Although veterinary students may also experience psychological distress in association with their training, little work has focused on the way that these students use alcohol to cope with their distress. The current study sought to examine the severity of depressive symptoms and alcohol consumption among veterinary students as well as students' specific motives for drinking alcohol. The majority of our sample reported experiencing at least one depressive symptom, and a significant proportion engaged in high-risk drinking, with men reporting more harmful alcohol use patterns. Drinking motives related to managing internal bodily and emotional states accounted for variance in drinking patterns. Further, drinking to ameliorate negative emotions partially accounted for the relationship between psychological distress and high-risk drinking. The results of this study suggest that depressive symptoms among veterinary students may be related to harmful drinking patterns, due to alcohol being used as a coping mechanism to regulate emotions. The findings from this study can be used to develop targeted interventions to promote psychological well-being among veterinary students.

    Adopting a developmental epidemiology perspective, the current study examines sources of risk heterogeneity for internalizing symptomatology among children of alcoholic parents (COAs). Parent-based factors, including comorbid diagnoses and the number of alcoholic parents in the family, as well as child-based factors, namely child gender, formed the indicators of heterogeneity. Following a novel approach to cross-study methods, we present a three-stage analysis involving measurement development using item response theory, examination of study effects on latent trajectories over time using latent curve modeling, and prediction of these latent trajectories testing our theoretically derived hypotheses in two longitudinal investigations across both mother- and self-reported symptomatology. Specifically, we replicated previous findings that parent alcoholism has a unique effect on child internalizing symptoms, above and beyond those of both parent depression and antisocial personality disorder. However, we also found important subgroup differences, explaining heterogeneity within COAs' risk profile in terms of the number of alcoholic parents in the family, comorbid diagnoses for the alcoholic parent and, for self-reported symptoms, child gender. Such factors serve to refine the definition of risk among COAs, suggesting a more severely impaired target group for preventive interventions, identifying the significance of familial alcoholism in individual differences underlying internalizing symptoms over time, and further specifying the distal risk matrix for an internalizing pathway to alcohol involvement.

    Objective: This study examined initiation of alcohol use among adolescents, in relation to their earlier traumatic experiences and symptoms of posttraumatic stress disorder (PTSD). Method: Data were from a longitudinal study of children of Puerto Rican background living in New York City's South Bronx and in San Juan, Puerto Rico. The subsample (n = 1,119; 51.7% male) of those who were 10–13 years old and alcohol naive at baseline was used in the analyses. Results: Alcohol-use initiation within 2 years after baseline was significantly more common among children reporting both trauma exposure and 5 or more of a maximum of 17 PTSD symptoms at baseline (adjusted odds ratio = 1.84, p 7 < .05) than among those without trauma exposure, even when potentially shared correlates were controlled for. Children with trauma exposure but with fewer than five PTSD symptoms, however, did not differ significantly from those without trauma exposure, with regard to later alcohol use. Conclusions: PTSD symptoms in children 10–13 years old may be associated with early onset of alcohol use. It is important to identify and treat PTSD-related symptoms in pre-adolescent children.

    Abuse and dependence to heroin has evolved into a global epidemic as a significant clinical and societal problem with devastating consequences. Repeated exposure to heroin can induce long-lasting behavioral sensitization and withdrawal. Pharmacological activation of 5-HT2C receptors (5-HT2CRs) suppresses psychostimulant-induced drug-seeking and behavioral sensitization. The present study examined the effect of a selective 5-HT2CR agonist lorcaserin on behavioral sensitization and naloxone-precipitated withdrawal symptoms in heroin-treated mice. Male mice received heroin (1.0 mg/kg, s.c.) twice a day for 3 days and then drug treatment was suspended for 5 days. On day 9, a challenge dose of heroin (1.0 mg/kg) was administered to examine the expression of behavioral sensitization. Lorcaserin administered during the development, withdrawal or expression stage suppressed heroin-induced behavioral sensitization on day 9. Another cohort of mice received increasing doses of heroin over a 4.5-day period. Lorcaserin, or the positive control clonidine (an α2-adrenoceptor agonist) suppressed naloxone-precipitated withdrawal symptoms in heroin-treated mice. These findings suggest that activation of 5-HT2CRs suppresses behavioral sensitization and withdrawal in heroin-treated mice. Thus, pharmacological activation of 5-HT2CRs may represent a new avenue for the treatment of heroin addiction.

    Alcoholism is a major public health problem and resembles, in many ways, other chronic relapsing medical conditions. At least 2 separate dimensions of its symptomatology offer targetable pathophysiological mechanisms. Systems that mediate positive reinforcement by alcohol are likely important targets in early stages of the disease, particularly in genetically susceptible individuals. In contrast, long term neuroadaptive changes caused by chronic alcohol use primarily appear to affect systems mediating negative affective states, and gain importance following a prolonged history of dependence. Feasibility of pharmacological treatment in alcoholism has been demonstrated by a first wave of drugs which consists of 3 currently approved medications, the aldehyde dehydrogenase blocker disulfiram, the opioid antagonist naltrexone (NTX) and the functional glutamate antagonist acamprosate (ACM). The treatment toolkit is likely to be expanded in the near future. This will improve overall efficacy and allow individualized treatment, ultimately taking in account the patient's genetic makeup. In a second wave, early human efficacy data are available for the 5HT3 antagonist ondansetron, the GABA-B agonist baclofen and the anticonvulsant topiramate. The third wave is comprised of compounds predicted to be effective based on a battery of animal models. Using such models, a short list of additional targets has accumulated sufficient preclinical validation to merit clinical development. These include the cannabinoid CB1 receptor, receptors modulating glutamatergic transmission (mGluR2, 3 and 5), and receptors for stress-related neuropeptides corticotropin releasing factor (CRF), neuropeptide Y (NPY) and nociceptin. Once novel treatments are developed, the field faces a major challenge to assure their delivery to patients.

    Plasma concentrations of lipoprotein (a) (Lp(a)) were studied in 11 male alcoholics at the end of a drinking period and monitored during subsequent abstinence. Lp(a) levels showed a daily increase for four consecutive days after the beginning of abstinence, the values for the third and the fourth day being significantly higher than those of the first day. The changes in Lp(a) showed no association with the changes in low density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol levels. In one alcoholic subject with a heterozygous form of familial hypercholesterolemia who was monitored for 11 days, the Lp(a) levels rose up to the fourth day and remained at a high level thereafter. These results suggest that ethanol ingestion may be associated with a lower of Lp(a) levels, which may contribute to the delayed progression of atherosclerosis observed in alcohol drinkers.

    Objective Posttraumatic stress disorder (PTSD), alcohol use, and alcohol-related consequences have been linked to emotion dysregulation. Sex differences exist in both emotion regulation dimensions and alcohol use patterns. This investigation examined facets of emotion dysregulation as potential mediators of the relationship between PTSD symptoms and alcohol-related consequences and whether differences may exist across sexes. Methods Participants included 240 college students with a trauma history who reported using alcohol within the past three months and completed measures of PTSD symptoms, emotion dysregulation, alcohol consumption, alcohol-related consequences, and negative affect. The six facets of emotion dysregulation were examined as mediators of the relationship between PTSD symptoms and alcohol-related consequences in the full sample and by sex. Results There were differences in sexes on several variables, with women reporting higher PTSD scores and Lack of Emotional Awareness. Men reported significantly higher drinks per week in a typical week and a heavy week. There were significant associations between the variables for the full sample, with PTSD showing associations with five facets of emotion dysregulation subscales: Impulse Control Difficulties when Upset, Difficulties Engaging in Goal-Directed Behavior, Nonacceptance of Emotional Responses, Lack of Emotional Clarity, and Limited Access to Emotion Regulation Strategies. Alcohol-related consequences were associated with four aspects of emotion dysregulation: Impulse Control Difficulties when Upset, Difficulties Engaging in Goal-Direct Behavior, Nonacceptance of Emotional Reponses, and Limited Access to Emotion Regulation Strategies. Two aspects of emotion regulation, Impulse Control Difficulties and Difficulties Engaging in Goal Directed Behavior, mediated the relationship between PTSD symptoms and alcohol-related consequences in the full sample, even after adjusting for the effects of negative affect

    Benzodiazepines (BZDs) are the drug of choice for the suppression of alcohol withdrawal symptoms. Gabapentin, a drug approved for use as adjunctive therapy in the treatment of partial seizures, has none of the BZD-type difficulties (drug interactions, abuse potential). We retrospectively report on the use of gabapentin for ethanol withdrawal in 49 patients. Thirty-one patients were treated in the outpatient program and 18 in the general inpatient psychiatric unit. Positive outcomes as evidenced by completion of gabapentin therapy were achieved in 25 out of 31 outpatients and 17 out of 18 inpatients. Statistical significance was reached regarding the positive relationship between prior ethanol use and inpatient "as needed" benzodiazepine use. Both sets of data suggest that gabapentin works well for the mild to moderate alcohol withdrawal patient.

    Gamma-aminobutyric acid (GABA) dysfunction is a known feature of alcoholism. We investigated GABA-B receptor activity in 3-week abstinent alcoholics using the growth hormone (GH) response to baclofen, a GABA-B receptor agonist. The study aimed to investigate the relationship between GABA-B receptor activity and alcohol withdrawal. GH response to baclofen was measured in alcohol-dependent males without depression (n = 22) who were on day 21 of alcohol abstinence and in healthy control male subjects (n = 23). After 20mg baclofen was given orally to the subjects, blood samples for GH assay were obtained every 30 min for the subsequent 150 min. The patients were divided into two subgroups (continuing withdrawal and recovered withdrawal subgroups) according to their withdrawal symptom severity scores on day 21 of alcohol cessation. Baclofen administration significantly altered GH secretion in the controls, but not in the patients. When GH response to baclofen was assessed as DeltaGH, it was lower in the patients with continuing withdrawal symptoms than in the controls and in the recovered withdrawal group. Impaired GH response to baclofen in all patients mainly pertained to the patients whose withdrawal symptoms partly continued. Our results suggest that reduced GABA-B receptor activity might be associated with longer-term alcohol withdrawal symptoms in alcoholic patients.

    Posttraumatic stress disorder (PTSD) and alcohol dependence (AD) frequently co-occur, although results of both cross-sectional and longitudinal studies evaluating the nature of their relationship have been mixed. There has been varied support for competing models explaining how these conditions influence one another. To assess both the self-medication and mutual maintenance models, as well as examine the potential moderating role of drinking motives, the current study used Generalized Estimating Equations to evaluate daily associations for an average of 7.3 days between PTSD symptoms and alcohol use in a mixed-gender sample of individuals who met criteria for both PTSD and AD. Results generally supported a self-medication model with elevated PTSD symptoms predictive of greater alcohol use on that same day and on the following day. Contrary to a mutual maintenance model prediction, drinking did not predict next-day PTSD symptoms. Results also indicated that both coping and enhancement drinking motives were significant moderators of the PTSD and drinking relationships, suggesting that these relationships may be more or less salient depending on an individual’s particular drinking motivations. For example, among those higher on coping drinking motives, a 1-unit increase in PTSD symptom severity was associated with a 37% increase in amount of alcohol consumed the same day, while among those low on coping drinking motives, a 1-unit PTSD increase was associated with only a 10% increase in alcohol consumption. We discuss implications of these findings for the larger literature on the associations between PTSD and alcohol use as well as for clinical interventions. PMID:24661174

    A total of 54 patients with alcoholism were studied during abstinence. Of these, 29 patients in the experimental group received basal therapy supplemented with physical treatment consisting of transcranial dynamic magnetotherapy (TcDMT), while the control group of 25 patients received only basal therapy. Comparison of the status of patients in the experimental and control groups during treatment demonstrated advantages of TcDMT in relation to improving the functional state of the CNS, memory, and attention, the autonomic nervous system, and the psychoemotional status of the patients (with decreases in the severity of anxiety and depression).

    Relationships among adult children of alcoholics (ACOAs) and parent and peer relations and depressive mood were examined among 136 ACOAs and 436 non-ACOAs. As compared to non-ACOAs, ACOAs reported less positive relationships to mothers, fathers, and peers, and more depressive mood; however, more positive relationships to parents and peers significantly reduced the strength of the association between ACOA categorization and depressive mood. Examination of data from ACOAs alone revealed that maternal alcoholism was related to less positive relationships to their mothers and to their peers; however, paternal alcoholism did not predict the quality of the relationship to fathers, mothers, or peers. Attachment to parents and peers and the gender of the alcohol-abusing parent were associated with depressive symptoms among ACOAs.

    In the weeks following the terrorist attacks of September 11, 2001, social commentators argued that America had profoundly "changed." In light of these arguments and the literature on disasters, we examine the immediate and longer-term mental health consequences of September 11th using a national sample of full-time American workers. We model the effects of temporal proximity to the attacks on depressive symptoms and alcohol consumption, while controlling for demographic characteristics. Our data revealed a significant increase in the number of depressive symptoms reported during the 4 weeks after the attacks. In the subsequent weeks, levels of depressive symptoms returned to pre-September 11th levels. Contrary to expectations, there was some indication of decreased alcohol consumption after September 11th, although these effects were modest. These analyses provide little support for popular assertions that September 11th resulted in lasting and measurable impacts on Americans' well-being.

    Opioid abuse and dependence have evolved into an international epidemic as a significant clinical and social problem with devastating consequences. Repeated exposure to the opioid, for example morphine, can induce profound, long-lasting behavioral sensitization and physical dependence, which are thought to reflect neuroplasticity in neural circuitry. Central serotonin (5-HT) neurotransmission participates in the development of dependence on and the expression of withdrawal from morphine. Serotonin 5-HT2C receptor (5-HT2CR) agonists suppress psychostimulant nicotine or cocaine-induced behavioral sensitization and drug-seeking behavior; however, the impact of 5-HT2CR agonists on behaviors relevant to opioid abuse and dependence has not been reported. In the present study, the effects of 5-HT2CR activation on the behavioral sensitization and naloxone-precipitated withdrawal symptoms were examined in mice underwent repeated exposure to morphine. Male mice received morphine (10 mg/kg, s.c.) to develop behavioral sensitization. Lorcaserin, a 5-HT2CR agonist, prevented the induction and expression, but not the development, of morphine-induced behavioral sensitization. Another cohort of mice received increasing doses of morphine over a 7-day period to induce morphine-dependence. Pretreatment of lorcaserin, or the positive control clonidine (an alpha 2-adrenoceptor agonist), ameliorated the naloxone-precipitated withdrawal symptoms. SB 242084, a selective 5-HT2CR antagonist, prevented the lorcaserin-mediated suppression of behavioral sensitization and withdrawal. Chronic morphine treatment was associated with an increase in the expression of 5-HT2CR protein in the ventral tegmental area, locus coeruleus and nucleus accumbens. These findings suggest that 5-HT2CR can modulate behavioral sensitization and withdrawal in morphine-dependent mice, and the activation of 5-HT2CR may represent a new avenue for the treatment of opioid addiction.

    Background Alcohol withdrawal syndrome is a potentially life-threatening condition, which can occur when patients with alcohol use disorders undergo general anesthesia. Excitatory amino acids, such as glutamate, act as neurotransmitters and are known to play a key role in alcohol withdrawal syndrome. To understand this process better, we investigated the influence of isoflurane, sevoflurane, and desflurane anesthesia on the profile of excitatory and inhibitory amino acids in the nucleus accumbens (NAcc) of alcohol-withdrawn rats (AWR). Methods Eighty Wistar rats were randomized into two groups of 40, pair-fed with alcoholic or non-alcoholic nutrition. Nutrition was withdrawn and microdialysis was performed to measure the activity of amino acids in the NAcc. The onset time of the withdrawal syndrome was first determined in an experiment with 20 rats. Sixty rats then received isoflurane, sevoflurane, or desflurane anesthesia for three hours during the withdrawal period, followed by one hour of elimination. Amino acid concentrations were measured using chromatography and results were compared to baseline levels measured prior to induction of anesthesia. Results Glutamate release increased in the alcohol group at five hours after the last alcohol intake (p = 0.002). After 140 min, desflurane anesthesia led to a lower release of glutamate (p < 0.001) and aspartate (p = 0.0007) in AWR compared to controls. GABA release under and after desflurane anesthesia was also significantly lower in AWR than controls (p = 0.023). Over the course of isoflurane anesthesia, arginine release decreased in AWR compared to controls (p < 0.001), and aspartate release increased after induction relative to controls (p20min = 0.015 and p40min = 0.006). However, amino acid levels did not differ between the groups as a result of sevoflurane anesthesia. Conclusions Each of three volatile anesthetics we studied showed different effects on excitatory and inhibitory amino acid concentrations. Under

    Objective: There is strong evidence that depression anticipates later drinking problems among adults. These associations have not been consistently documented during adolescence, perhaps because little attention has been given to individual differences in peer relationships, which are the primary setting for adolescent alcohol consumption. This study investigated associations between depressive affect and alcohol misuse as moderated by peer group acceptance. Method: A community sample of 1,048 Swedish youth provided self-reports of depressive symptoms and intoxication frequency at annual intervals across the middle school years (seventh grade: M = 13.21 years old; eighth grade: M = 14.27 years old; ninth grade: M = 15.26 years old). Peer nominations provided a measure of individual acceptance. Results: Growth curve analyses revealed differences in the extent to which initial levels of depressive symptoms predicted the slope of increase in intoxication frequency. Higher levels of depressive symptoms at the outset anticipated sharp increases in intoxication frequency from seventh to ninth grades for low-accepted youth but not for average- or high-accepted youth. Conclusions: poor peer relations and depressive affect are vulnerabilities that set the stage for escalating adolescent alcohol misuse. Across the middle school years, when most youth have their first experiences with alcohol, peer difficulties exacerbated the tendency of depressed youth to drink to excess. PMID:26098034

    This single site retrospective observational study assessed the evolution of sedation therapy for severe alcohol withdrawal syndrome in the intensive care unit. Patient records for 2 intervals were reviewed: Interval 1, which included 87 intensive care unit patients admitted January 2005 through September 2007, for whom benzodiazedpine monotherapy was utilized; and Interval 2, January 2010 through December 2010, for whom 54 of 84 (64.3%) intensive care unit patients, including all those intubated, received adjunctive agents, including dexmedetomidine or propofol. Clinical management was similar for both intervals, as well as prevalence of alcohol withdrawal syndrome versus total adult hospital admissions and comorbid conditions. Overall, respiratory failure (53 versus 39%), seizures (36 versus 18%), and pneumonia (51 versus 38%) were less frequent during Interval 2 (all p < .05), with lower benzodiazedpine basal dose requirements for those given adjunctive therapy. However, if instances of pneumonia or respiratory failure related to seizures prior to intensive care unit admission are excluded, the prevalence of these complications was similar (p = ns) for Interval 1 and Interval 2. Intensive care unit and hospital length of stay were not altered by adjunctive therapy, which was typically employed for more severely affected patients. High intensity sedation with adjunctive drugs led to few cardiovascular adverse events and may have facilitated management, but did not alter intensive care unit course of severe alcohol withdrawal syndrome.

    Depressive symptoms and alcohol use are frequently positively associated during adolescence. This study aimed to assess the heritability of each phenotype across adolescence; to assess potential shared liabilities; to examine changes in the nature of shared liabilities across adolescence; and to investigate potential causal relationships between depressive symptoms and alcohol use. We studied a longitudinally assessed sample of adolescent Finnish twins (N = 1,282) to test hypotheses about genetic and environmental influences on these phenotypes within and across ages, using data from assessments at ages 12, 14, and 17.5 years. The heritability of depressive symptoms is consistent across adolescence (~40–50%), with contributions from common and unique environmental factors. The heritability of alcohol use varies across time (a2 = .25–.44), and age 14 alcohol use is heavily influenced by shared environmental factors. Genetic attenuation and innovation were observed across waves. Modest to moderate genetic (rA = .26–.59) and environmental (rC = .30–.63) correlations between phenotypes exist at all ages, but decrease over time. Tests for causal relationships between traits differed across ages and sexes. Intrapair MZ difference tests provided evidence for reciprocal causation in girls at ages 14 and 17.5. Formal causal models suggested significant causal relationships between the variables in both boys and girls. The association between depressive symptoms and alcohol use during adolescence is likely due to a combination of shared genetic and environmental influences and causal influences. These influences are also temporally dynamic, complicating efforts to understand factors contributing to the relationship between these outcomes. PMID:20890653

    Background Endogenous cannabinoids such as anandamide and 2-arachidonoylglycerol (2-AG) exert important regulatory influences on neuronal signaling, participate in short- and long-term forms of neuroplasticity, and modulate stress responses and affective behavior in part through the modulation of neurotransmission in the amygdala. Alcohol consumption alters brain endocannabinoid levels, and alcohol dependence is associated with dysregulated amygdalar function, stress responsivity and affective control. Methods The consequence of long-term alcohol consumption on the expression of genes related to endocannabinoid signaling was investigated using quantitative RT-PCR analyses of amygdala tissue. Two groups of ethanol-exposed rats were generated by maintenance on an ethanol liquid diet (10%): one group received continuous access to ethanol for 15 days, while the second group was given intermittent access to the ethanol diet (5 days/week for 3 weeks). Control subjects were maintained on an isocaloric ethanol-free liquid diet. To provide an initial profile of acute withdrawal amygdala tissue was harvested following either 6 or 24 hours of ethanol withdrawal. Results Acute ethanol withdrawal was associated with significant changes in mRNA expression for various components of the endogenous cannabinoid system in the amygdala. Specifically, reductions in mRNA expression for the primary clearance routes for anandamide and 2-AG (FAAH and MAGL, respectively) were evident, as were reductions in mRNA expression for CB1, CB2 and GPR55 receptors. Although similar alterations in FAAH mRNA were evident following either continuous or intermittent ethanol exposure, alterations in MAGL and cannabinoid receptor-related mRNA (e.g. CB1, CB2, GPR55) were more pronounced following intermittent exposure. In general, greater withdrawal-associated deficits in mRNA expression were evident following 24 versus 6 hours of withdrawal. No significant changes in mRNA expression for enzymes involved in

    Objective: This study considered the processes linking functional limitation and pain with depressive symptoms and two alcohol-related outcomes (past-month drinking and problematic drinking) over a 3-year period. Method: Data were drawn from a two-wave Miami-Dade County community study of people with physical disabilities (N = 559). Structural equation modeling was used to assess whether depressive symptoms mediated the associations among functional limitation, bodily pain, and the alcohol-related outcomes considered, and whether these associations were moderated by gender. Results: When the effects of the sociodemographic control variables were controlled for, depressive symptoms partly explained the effects of Wave 1 functional limitation and bodily pain on problematic drinking at Wave 2. The mediating effects of depressive symptoms on problematic drinking were significantly greater for men than for women. Conclusions: The findings demonstrate clear linkages between two physical health indicators, depressive symptoms and drinking, and highlight the circumstances in which gender matters most for understanding these associations.

    Purpose Attention-deficit/hyperactivity disorder (ADHD) has been shown to be related to a higher risk of developing psychiatric problems such as depressive disorders, substance use disorder, and impulsivity. Adults who have comorbid ADHD and alcohol use disorder (AUD) are at greater risk of negative outcomes. Thus, it is important to evaluate the relationship of ADHD symptoms and the severity of alcohol-related problems among patients with AUD. The aim of the present study was to evaluate the effect of ADHD symptoms on severity of alcohol-related problems, while controlling the effects of depression and impulsivity in a sample of inpatients with AUD. Patients and methods Participants (n=190) were evaluated with the Beck Depression Inventory, the Short Form Barratt Impulsiveness Scale, the Michigan Alcohol Screening Test, and the Adult ADHD Self-Report Scale. Results Severity of the scale scores was positively correlated with each other. Although severity of depression and impulsivity (particularly non-planning impulsivity) predicted the severity of alcohol-related problems in a linear regression model, when severity of ADHD symptoms was included in the analysis, the inattentive subscale score, in particular, predicted the severity of alcohol-related problems together with non-planning impulsivity, whereas depression was no longer a predictor. Conclusion These findings suggest that, together with non-planning impulsivity, symptoms of ADHD (particularly inattentive factor) are an important factor that predict alcohol-related problems, while controlling the severity of depressive symptoms among inpatients with AUD.

    Binge-drinking is the most prevalent form of alcohol abuse and while an early life history of binge-drinking is a significant risk factor for subsequent alcoholism and co-morbid affective disorders, relatively little is known regarding the biobehavioral impact of binge-drinking during the sensitive neurodevelopmental period of adolescence. In adult mice, a month-long history of binge-drinking elicits a hyper-glutamatergic state within the nucleus accumbens (Acb), coinciding with hyper-anxiety. Herein, we employed a murine model of binge-drinking to determine whether or not: (1) withdrawal-induced changes in brain and behavior differ between adult and adolescent bingers; and (2) increased behavioral signs of negative affect and changes in Acb expression of glutamate-related proteins would be apparent in adult mice with less chronic binge-drinking experience (14 days, approximating the duration of mouse adolescence). Adult and adolescent male C57BL/6J mice were subjected to a 14-day binge-drinking protocol (5, 10, 20 and 40% alcohol (v/v) for 2 h/day), while age-matched controls received water. At 24 h withdrawal, half of the animals from each group were assayed for negative affect, while tissue was sampled from the shell (AcbSh) and core (AcbC) subregions of the remaining mice for immunoblotting analyses. Adult bingers exhibited hyper-anxiety when tested for defensive marble burying. Additionally, adult bingers showed increased mGlu1, mGlu5, and GluN2b expression in the AcbSh and PKCε and CAMKII in the AcbC. Compared to adults, adolescent mice exhibited higher alcohol intake and blood alcohol concentrations (BACs); however, adolescent bingers did not show increased anxiety in the marble-burying test. Furthermore, adolescent bingers also failed to exhibit the same alcohol-induced changes in mGlu and kinase protein expression seen in the adult bingers. Irrespective of age, bingers exhibited behavioral hyperactivity in the forced swim test (FST) compared to water

In an integrative data analysis, we combined observations over ages 2 through 17 from two longitudinal studies of children of alcoholic parents and matched controls recruited from the community. Using a mixed modeling approach, we tested whether children showed elevated mother- and child-reported internalizing symptoms (a) at the same time that parents showed alcohol-related consequences (time-varying effects), (b) if parents showed greater alcohol-related consequences during the study period (proximal effects), and (c) if parents had a lifetime diagnosis of alcoholism that predated the study period (distal effects). No support for time-varying effects was found; proximal effects of mothers’ alcohol-related consequences on child-reported internalizing symptoms were found and distal effects of mother and father alcoholism predicted greater internalizing symptoms among COAs. Implications for the time-embedded relations between parent alcoholism and children’s internalizing symptoms are discussed. PMID:17891557

    Background Current initiatives to update diagnostic criteria for alcohol use disorders (AUDs) have stimulated dialogue about the usefulness of indicators of alcohol consumption in the diagnosis of AUDs. Methods This study used Rasch model analyses to examine the properties of alcohol consumption descriptors and AUD symptoms among 3,382 treatment-seeking adolescents, aged 12–18 years, in the DATOS-A (USDHHS, 1993–1995) baseline assessment, and evaluated the predictive validity of different scoring methods (with and without alcohol consumption) for 12-month alcohol involvement. Results Rasch model analyses supported the unidimensionality of indices of alcohol consumption and AUD symptoms. Test information functions showed that adding consumption items provides further information at all points of the alcohol involvement severity spectrum. Combining AUD symptoms with indices of alcohol consumption provided better prediction of alcohol involvement after treatment than either AUD symptoms counts or DSM-IV dependence diagnosis alone. Differential item functioning (DIF), however, was observed for select items. Generally, indices of drinking “too much too fast” were more severe for females, African Americans and Hispanics, while the opposite was true for items measuring “too much too often”. For age, “too much too often” items were more severe for the younger (12–14yrs) age group, and AUD symptoms were more severe for the older (15–18yrs) age group. Conclusions Indices of alcohol consumption can be validly scaled along with AUD symptoms in this population, and their inclusion provides statistical measurement advantages. Nevertheless, caution is necessary in using consumption items in measuring alcohol involvement due to DIF observed across sex, race and age. PMID:21146941

    Aims Alcohol consumption and internalizing symptoms, which often co-occur, pose considerable risk to the developing adolescent and have lasting public health consequences. Previous research has documented concurrent associations between alcohol use and symptoms of anxiety and depression, but the dearth of longitudinal research, particularly for ethnic minority youth, raises questions about the replicability and causal direction of these effects. The goal of the present research was to clarify these issues, and investigate whether different facets of anxiety and depression are uniquely associated with alcohol use in adolescence. Method The present research examined cross-lagged relations between frequency of alcohol use and internalizing symptoms, using data from a longitudinal study of 674 Mexican-origin youth (50% female) assessed at ages 14 and 16. Results Alcohol use at age 14 prospectively predicted increases in overall internalizing symptoms, and overall internalizing symptoms at age 14 prospectively predicted increases in alcohol use. Reciprocal effects were consistently found for the general distress and anxious arousal facets, but not for anhedonic depression and a scale measuring the cognitive aspects of anxiety. Conclusions The findings provide evidence of reciprocal relations between alcohol use and internalizing symptoms, but also highlight the danger of treating all symptoms of anxiety and depression as interchangeable components of a single broad domain. Instead, symptoms common to both anxiety and depressive disorders (e.g., general distress) have the most robust reciprocal relations with alcohol use. Thus, intervention programs aimed at reducing early alcohol use by Mexican-origin youth should target this component of the internalizing domain. PMID:26999352

    Negative symptoms of schizophrenia (NSS), related to hypodopaminergic activity in the mesocortical pathway and prefrontal cortex, are predictive of poor outcomes and have no effective treatment. Use of dopamine-enhancing drugs (eg, psychostimulants) has been limited by potential adverse effects. This multicenter study examined lisdexamfetamine dimesylate (LDX), a d-amphetamine prodrug, as adjunctive therapy to antipsychotics in adults with clinically stable schizophrenia and predominant NSS. Outpatients with stable schizophrenia, predominant NSS, limited positive symptoms, and maintained on stable atypical antipsychotic therapy underwent a 3-week screening, 10-week open-label adjunctive LDX (20–70 mg/day), and 4-week, double-blind, randomized, placebo-controlled withdrawal. Efficacy measures included a modified Scale for the Assessment of Negative Symptoms (SANS-18) and Positive and Negative Syndrome Scale (PANSS) total and subscale scores. Ninety-two participants received open-label LDX; 69 received double-blind therapy with placebo (n=35) or LDX (n=34). At week 10 (last observation carried forward; last open-label visit), mean (95% confidence interval) change in SANS-18 scores was −12.9 (−15.0, −10.8; P<0.0001). At week 10, 52.9% of participants demonstrated a minimum of 20% reduction from baseline in SANS-18 score. Open-label LDX was also associated with significant improvement in PANSS total and subscale scores. During the double-blind/randomized-withdrawal phase, no significant differences (change from randomization baseline) were found between placebo and LDX in SANS-18 or PANSS subscale scores. In adults with clinically stable schizophrenia, open-label LDX appeared to be associated with significant improvements in negative symptoms without positive symptom worsening. Abrupt LDX discontinuation was not associated with positive or negative symptom worsening. Confirmation with larger controlled trials is warranted. PMID:23756608

    Temperament and character factors are strongly related to the developmental, clinical, and treatment aspects of alcohol dependence. This study had the aim of revealing the underlying personality structure and individual differences in the symptoms of alcohol dependence measured by multiple severity indicators. Patients with alcohol dependence exhibited higher levels of novelty seeking and harm avoidance, and lower levels of persistence, self-directedness, and cooperativeness. Especially novelty seeking was connected with more severe alcohol dependence. These characteristics could be useful targets of interventions and Temperament and Character Inventory is therefore a useful measurement to identify patients with more severe alcohol-related problems.

    Previous research has established a link between ethnic discrimination and poor mental health, yet the process by which this relationship occurs remains unclear. It has been hypothesized that the potential mechanisms accounting for the negative consequences of ethnic discrimination may be through stress responses and health behaviors (Pascoe & Smart Richman, 2009). The present study sought to examine the role of traumatic stress symptoms and alcohol use in mediating the relationship between ethnic discrimination and depressive symptoms. Two aspects of ethnic discrimination were assessed, namely source of discrimination and reaction to discrimination. The sample for the current study included 244 adult Latinos averaging approximately 40 years of age (SD = 15.29; range 18-85). Participants, which were comprised of mainly women (66%, n = 156), completed a series of paper-and-pencil questionnaires. Multiple mediator analyses revealed that, among U.S.-born but not foreign-born Latinos, both source of discrimination and reaction to discrimination were related to increased traumatic stress symptoms, which, in turn, was associated with depressive symptomatology. The traumatic stress symptoms pathway showed a robust indirect effect while alcohol use was not a statistically significant mediator. These major findings suggest that, while ethnic discrimination has a direct effect on depression, increased traumatic stress can account for this relationship particularly for U.S.-born Latinos. The findings are discussed within a stress and coping framework. (PsycINFO Database Record

    Heavy drinking causes hangover symptoms, because the action of alcohol dehydrogenase forms acetaldehyde, which is metabolized by acetaldehyde dehydrogenase into acetate. Red ginseng shows positive effects on alcohol metabolism in animal studies. We investigated the effects of red ginseng on relieving alcohol and hangover symptoms in 25 healthy men in a randomized crossover study. At each visit (0, 1, and 2 weeks), the subjects drank 100 mL whiskey (40% alcohol) and either 100 mL water or 100 mL of a 0.321 mg mL(-1) red ginseng anti-hangover drink (RGD). We took blood samples periodically until 240 min after alcohol consumption, and we investigated the blood profiles, alcohol levels, and acetaldehyde levels. We also measured anthropometric parameters, expiratory air-alcohol levels, and hangover symptoms. The plasma alcohol concentrations within the RGD group were significantly lower than those within the placebo group after 30 min (p = 0.002), 45 min (p = 0.016), and 60 min (p = 0.009); the areas under the response curves revealed a positive effect of RGD (p = 0.051). Furthermore, the expiratory alcohol concentration was significantly lower after 30 min (p = 0.005) and 60 min (p = 0.065), and the areas under the response curves (p = 0.058) likewise revealed a positive effect of RGD. The plasma acetaldehyde level was significantly elevated at 120 min (p = 0.020), but the areas under the response curves showed a similar trend (p = 0.054). While the plasma acetaldehyde concentration slightly increased, the RGD showed positive effects on hangover symptoms. Considering the reduction of plasma alcohol levels, expiratory concentrations, and hangover severity, we conclude that red ginseng relieves the symptoms of alcohol hangover.

    Extensive genetic and genomic studies of the relationship between alcohol drinking preference and withdrawal severity have been performed using animal models. Data from multiple such publications and public data resources have been incorporated in the GeneWeaver database with >60,000 gene sets including 285 alcohol withdrawal and preference-related gene sets. Among these are evidence for positional candidates regulating these behaviors in overlapping quantitative trait loci (QTL) mapped in distinct mouse populations. Combinatorial integration of functional genomics experimental results revealed a single QTL positional candidate gene in one of the loci common to both preference and withdrawal. Functional validation studies in Ap3m2 knockout mice confirmed these relationships. Genetic validation involves confirming the existence of segregating polymorphisms that could account for the phenotypic effect. By exploiting recent advances in mouse genotyping, sequence, epigenetics, and phylogeny resources, we confirmed that Ap3m2 resides in an appropriately segregating genomic region. We have demonstrated genetic and alcohol-induced regulation of Ap3m2 expression. Although sequence analysis revealed no polymorphisms in the Ap3m2-coding region that could account for all phenotypic differences, there are several upstream SNPs that could. We have identified one of these to be an H3K4me3 site that exhibits strain differences in methylation. Thus, by making cross-species functional genomics readily computable we identified a common QTL candidate for two related bio-behavioral processes via functional evidence and demonstrate sufficiency of the genetic locus as a source of variation underlying two traits.

    Background Peroxisome proliferator-activated receptor (PPAR) agonists reduce voluntary ethanol consumption in rat models and are promising therapeutics in the treatment of drug addictions. We studied the effects of different classes of PPAR agonists on chronic ethanol intake and preference in mice with a genetic predisposition for high alcohol consumption and then examined human genome wide association data for polymorphisms in PPAR genes in alcohol-dependent subjects. Methods Two different behavioral tests were used to measure intake of 15% ethanol in C57BL/6J male mice: 24-hour two-bottle choice and limited access (3-hour) two-bottle choice, drinking in the dark. We measured the effects of pioglitazone (10 and 30 mg/kg), fenofibrate (50 and 150 mg/kg), GW0742 (10 mg/kg), tesaglitazar (1.5 mg/kg) and bezafibrate (25 and 75 mg/kg) on ethanol intake and preference. Fenofibric acid, the active metabolite of fenofibrate, was quantified in mouse plasma, liver, and brain by LC-MS/MS. Data from a human genome wide association study (GWAS) completed in the Collaborative Study on the Genetics of Alcoholism (COGA) was then used to analyze the association of single nucleotide polymorphisms (SNPs) in different PPAR genes (PPARA, PPARD, PPARG, and PPARGC1A) with two phenotypes: DSM-IV alcohol dependence (AD) and the DSM-IV criterion of withdrawal. Results Activation of two isoforms of PPARs, α and γ, reduced ethanol intake and preference in the two different consumption tests in mice. However, a selective PPARδ agonist or a pan agonist for all three PPAR isoforms did not decrease ethanol consumption. Fenofibric acid, the active metabolite of the PPARα agonist fenofibrate, was detected in liver, plasma, and brain after 1 or 8 days of oral treatment. The GWAS from COGA supported an association of SNPs in PPARA and PPARG with alcohol withdrawal and PPARGC1A with AD but found no association for PPARD with either phenotype. Conclusions We provide convergent evidence using both

    Attention deficits are often observed in children with prenatal alcohol exposure and attention-deficit/hyperactivity disorder (ADHD) is commonly diagnosed in this population. This study used an objective assessment tool to examine differences between alcohol-exposed and non-exposed children on core symptoms of ADHD: inattention, impulsivity, and hyperactivity. Two groups of individuals, aged 7-14years, participated in the study: alcohol-exposed children (AE, n=43), and non-exposed children (CON, n=54). Subjects were evaluated with the Quotient ADHD System, which provides objective data on ADHD core symptoms by combining an infrared motion tracking system and a computerized continuous performance task. Twelve separate ANCOVAs controlling for the effects of age and sex, were conducted on attention and motion variables. Results revealed that in comparison to the CON group, the AE group was significantly (p's<.05) less accurate, made an increased number of omission errors, had longer response latencies, and increased variability in response time. Moreover, the AE group spent less time staying still, and made an increased number of head movements, which traveled a larger distance, covered a greater area, and demonstrated a less complex movement pattern. No significant group differences were observed on the number of commission errors and temporal scaling. Our findings provide further support for the notion that inattention is a core deficit in children prenatally exposed to alcohol. Results from this study are also consistent with parent reports of increased hyperactivity. The Quotient ADHD System may be a useful objective measure of ADHD symptomatology in children with FASD.

    Background/Aims Nonsteroidal anti-inflammatory drugs relieve osteoarthritis (OA) symptoms but cause adverse effects. D-002, a mixture of beeswax alcohols, is effective against experimental OA. A pilot study found that D-002 (50 mg/day) for 8 weeks improves OA symptoms. The aim of this study was to investigate the effects of D-002 (50 to 100 mg/day) administered for 6 weeks on OA symptoms. Methods Patients with OA symptoms were double-blindly randomized to D-002 (50 mg) or placebo for 6 weeks. Symptoms were assessed by the Western Ontario and McMaster Individual Osteoarthritis Index (WOMAC) and the visual analog scale (VAS) scores. Patients without symptom improvement at week 3 were titrated to two daily tablets. The primary outcome was the total WOMAC score. WOMAC pain, joint stiffness and physical function scores, VAS score, and use of rescue medications were secondary outcomes. Results All randomized patients (n = 60) completed the study, and 23 experienced dose titration (two in the D-002 and 21 in the placebo groups). At study completion, D-002 reduced total WOMAC (65.4%), pain (54.9%), joint stiffness (76.8%), and physical function (66.9%) WOMAC scores, and the VAS score (46.8%) versus placebo. These reductions were significant beginning in the second week, and became enhanced during the trial. The use of rescue medication by the D-002 (6/30) group was lower than that in the placebo (17/30) group. The treatment was well tolerated. Seven patients (two in the D-002 and five in the placebo group) reported adverse events. Conclusions These results indicate that D-002 (50 to 100 mg/day) for 6 weeks ameliorated arthritic symptoms and was well tolerated. PMID:24648802

In contrast to previous results, we observed no significant interactions between DRD4 and childhood adversity. Overall, results further highlight the need for longitudinal studies of gene × environment interaction in the behavioral sciences and the difficulty of identifying candidate gene × environment interaction effects that are consistent across studies.

    The aims of the present study were to characterize the relationship between plasma racemic methadone and its enantiomers' concentrations with respect to their pharmacodynamic effects and to investigate the influence of potential covariates on the pharmacodynamic parameters in patients on methadone maintenance treatment (MMT). Eighty-eight regular subjects at the Sheffield Care Trust Substance Misuse Services were studied. Samples of blood and urine were collected before the daily dose of methadone. Blood samples were taken up to 5 hours after dose. Total plasma concentrations of (RS)-methadone and total and unbound plasma concentrations of both enantiomers were measured by liquid chromatography-mass spectrometry. The Total Mood Disturbance Score (TMDS), the Objective Opioid Withdrawal Scale (OOWS), and the Subjective Opioid Withdrawal Scale (SOWS) were used as measures of mood and withdrawal. Population pharmacokinetic/pharmacodynamic analysis and subsequent multiple regression analysis were used to determine the factors influencing the pharmacodynamic effects of methadone. Significant decreases (P ≤ 0.04) were observed in the scores for the TMDS, SOWS, and OOWS for 5 hours after methadone dosage. The TMDS had returned to baseline by 10 hours after dose (P = 0.98), at which time the SOWS remained significantly below baseline (P = 0.001). Multiple regression analysis revealed that 33% of the overall variation in unbound (R)-methadone EC50 was explained by 3 variables, namely CYP3A activity (9%), age (16%), and sex (8%). Age also accounted for 8% and 9% of the variation in total (rac)- and (R)-methadone EC50. The present study has confirmed that the duration of mood change in the present study was shorter than the effect of methadone in stabilizing withdrawal symptoms. Thus, it is likely that a once-daily dose of methadone, albeit effective for preventing withdrawal, may not be sufficient to improve mood in some patients. Finally, it was established that CYP3A

    Problematic alcohol use and risk for dependence peak during late adolescence, particularly among first-year college students. Although students matriculating into college with depressive symptoms experience elevated risk for alcohol problems, few studies have examined the intervening mechanisms of risk. In this study, we examined depressed mood at college entry on prospective alcohol expectancies, drinking motives, and alcohol outcomes during the first year of college, adjusting for pre-college factors. Participants (N = 614; 59% female, 33% non-White) were incoming college students from three universities who completed online self-report surveys prior to matriculating into college and at the end of their first year in college. We utilized path analysis to test our hypotheses. In women, the path that linked depressive symptoms to consequences was primarily attributable to the effect of pre-college drinking to cope on drinking to cope in college, which in turn was associated with alcohol consequences. In men, the effect of depressive symptoms on alcohol consequences in college was independent of pre-college and college factors, thus indicating the need for research that identifies mechanisms of risk in males. Interventions that address coping deficits and motivations for drinking may be particularly beneficial for depressed adolescent females during this high-risk developmental period.

    Gabapentin is an antiepileptic drug shown to be effective in the treatment of pain disorders and appears to be useful as well for several psychiatric disorders, including bipolar disorder, anxiety disorders, alcohol withdrawal and cocaine dependence. Gabapentin, at a dose of 600 mg three times a day, was evaluated as an add-on medication to a standard detoxification regime in seven heroin dependent individuals undergoing outpatient opiate withdrawal treatment. All seven patients successfully completed opiate detoxification and commenced opiate antagonist treatment with naltrexone on day five of withdrawal treatment, as scheduled. No adverse event was noted. Gabapentin appeared to lead a reduction in symptomatic medication and an overall beneficial effect on symptoms of heroin withdrawal.

    The objective of the present study was to examine prospective, bidirectional associations among posttraumatic stress disorder (PTSD) symptoms, coping style, and alcohol involvement (use, consequences), in a sample of trauma-exposed students just entering college. We also sought to test the mechanistic role that coping may play in associations between PTSD symptoms and problem alcohol involvement over time. Participants (N=734) completed measures of trauma exposure, PTSD symptoms, coping, and alcohol use and consequences in September of their first college year (Y1) and again each September for the next two years (Y2–3). We observed reciprocal associations between PTSD and negative coping strategies. In our examination of a mediated pathway through coping, we found an indirect association from alcohol consequences and PTSD symptoms via negative coping, suggesting that alcohol consequences may exacerbate posttraumatic stress over time by promoting negative coping strategies. Trauma characteristics such as type (interpersonal vs. non-interpersonal) and trauma re-exposure did not moderate these pathways. Models also were invariant across gender. Findings from the present study point to risk that is conferred by both PTSD and alcohol consequences for using negative coping approaches, and through this, for posttraumatic stress. Interventions designed to decrease negative coping may help to offset this risk, leading to more positive outcomes for those students who enter college with trauma exposure. PMID:25528048

    Research on depression and effort has suggested "depressive blunting"-lower cardiovascular reactivity in response to challenges and stressors. Many studies, however, find null effects or higher reactivity. The present research draws upon motivational intensity theory, a broad model of effort that predicts cases in which depressive symptoms should increase or decrease effort. Because depressive symptoms can influence task-difficulty appraisals-people see tasks as subjectively harder-people high in depressive symptoms should engage higher effort at objectively easier levels of difficulty but also quit sooner. A sample of adults completed a mental effort challenge with four levels of difficulty, from very easy to difficult-but-feasible. Depressive symptoms were assessed with the CESD and DASS; effort-related cardiac activity was assessed via markers of contractility (e.g., the cardiac pre-ejection period [PEP]) obtained with impedance cardiography. The findings supported the theory's predictions. When the task was relatively easier, people high in depressive symptoms showed higher contractility (shorter PEP), consistent with greater effort. When the task was relatively harder, people high in depressive symptoms showed diminished contractility, consistent with quitting. The results suggest that past research has been observing a small part of a larger trajectory of trying and quitting, and they illustrate the value of a theoretically grounded analysis of depressive symptoms and effort-related cardiac activity.

    Drug addiction is a chronically relapsing disorder characterized by compulsion to seek and take the drug, loss of control in limiting intake and, eventually, the emergence of a negative emotional state when access to the drug is prevented. Both dopamine and corticotropin-releasing factor (CRF)-mediated systems seem to play important roles in the modulation of alcohol abuse and dependence. The present study investigated the effects of alcohol consumption on anxiety and locomotor parameters and on the activation of dopamine and CRF-innervated brain regions. Male Wistar rats were given a choice of two bottles for 31 days, one containing water and the other a solution of saccharin + alcohol. Control animals only received water and a solution of 0.2% saccharin. On the 31st day, animals were tested in the elevated plus-maze and open field, and euthanized immediately after the behavioral tests. An independent group of animals was treated with ethanol and used to measure blood ethanol concentration. Results showed that alcohol intake did not alter behavioral measurements in the plus-maze, but increased the number of crossings in the open field, an index of locomotor activity. Additionally, alcohol intake increased Fos-immunoreactivity (Fos-ir) in the prefrontal cortex, in the shell region of the nucleus accumbens, in the medial and central amygdala, in the bed nucleus of the stria terminalis, in the septal region, and in the paraventricular and dorsomedial hypothalamus, structures that have been linked to reward and to approach/withdrawal behavior. These observations might be relevant to a better understanding of the behavioral and physiological alterations that follow alcohol consumption.

    Purpose: To evaluate risk factors for deterioration of lower urinary tract symptoms (LUTS) in elderly men in a community-based, prospective longitudinal cohort study. Methods: In a suburban area in Korea, 1,514 subjects aged ≥45 years were randomly selected by systematic sampling. A total of 918 elderly subjects were enrolled in this in-depth clinical study in 2004. Of these, 547 participants were followed up for 3 years and the data was analyzed in 2014. Standard questionnaires were administered face-to-face by trained interviewers. After excluding women, 224 male participants with complete data including transrectal ultrasonography were included in the final analysis. LUTS were diagnosed using the International Prostate Symptom Score (IPSS) questionnaire. Symptom deterioration was defined as a score of ≥8 points during the 3-year follow-up period. Results: LUTS prevalence increased to 13.1% and the mean IPSS increased by 2.6 points during the 3-year period. After adjusting for confounders, a smoking history of ≥50 pack-years was an independent risk factor for deterioration of LUTS and storage subsymptoms compared with no history of smoking (3.1 and 5.1 odds, respectively). Physical activity had a protective effect on voiding subsymptoms. However, high protein diet and alcohol intake were not associated with LUTS deterioration. Conclusions: The LUTS prevalence among elderly men living in a suburban area increased to 13.1% and the IPSS increased by 2.6 points during the 3-year period. A history of heavy smoking, low physical activity, and high protein intake were associated with LUTS deterioration. However, there was no significant association between alcohol intake and LUTS deterioration. PMID:26620903

    Alcohol is a drug consumed at some time in life by up to 80% of the population according to western statistics. Wide differences in socioeconomic status in India contribute to various degrees and severity of alcoholism and its associated complications. The symptoms of alcohol withdrawal range from such minor ones as insomnia and tremulousness to severe complications such as withdrawal seizures and delirium tremens. Although alcohol withdrawal syndrome has been reported in the literature in post-operative periods and in Intensive Care Unit, there is paucity of information on treatment and preparation of a patient with alcohol withdrawal syndrome coming for emergency surgical procedures. The surgical stress and deranged liver function in such cases poses an additional challenge to the anaesthesiologist. Here, we report the successful management of a case of acute alcoholic delirium tremens who presented with hollow viscous perforation for emergency exploratory laparotomy. PMID:22701216

    2013-01-01

    Alcoholism (alcohol dependence) is characterized by a compulsion to seek and ingest alcohol (ethanol), loss of control over intake, and the emergence of a negative emotional state during withdrawal. Animal models are critical in promoting our knowledge of the neurobiological mechanisms underlying alcohol dependence. Here, we review the studies involving operant alcohol self-administration in rat models of alcohol dependence and withdrawal with the focus on the alcohol vapor model. In 1996, the first articles were published reporting that rats made dependent on alcohol by exposure to alcohol vapors displayed increased operant alcohol self-administration during acute withdrawal compared with nondependent rats (i.e., not exposed to alcohol vapors). Since then, it has been repeatedly demonstrated that this model reliably produces physical and motivational symptoms of alcohol dependence. The functional roles of various systems implicated in stress and reward, including opioids, dopamine, corticotropin-releasing factor (CRF), glucocorticoids, neuropeptide Y (NPY), γ-aminobutyric acid (GABA), norepinephrine, and cannabinoids, have been investigated in the context of alcohol dependence. The combination of models of alcohol withdrawal and dependence with operant self-administration constitutes an excellent tool to investigate the neurobiology of alcoholism. In fact, this work has helped lay the groundwork for several ongoing clinical trials for alcohol dependence. Advantages and limitations of this model are discussed, with an emphasis on what future directions of great importance could be. PMID:24290310

    The study examined the effect of adult children's disability on parents' physical health in later life and the extent to which parents' symptoms of alcoholism in mid-life moderates the link between children's disability and later life parental health. Analyses are based on data from the Wisconsin Longitudinal Study. The analytic sample included parents of children with developmental disabilities (n = 145) or mental health problems (n = 200) and 2,432 parents of unaffected children. The results showed that the negative health consequences in later life of having a child with a developmental disability were greater for those who showed more symptoms of alcoholism in mid-life. However, symptoms of alcoholism in mid-life did not significantly moderate the impact of an adult child's mental health problems on parents' later life physical health. The findings suggest a potential area where gerontological social workers could intervene, given the negative impact of symptoms of alcoholism on the health of aging parents of children with a disability who may be significantly more susceptible to the negative health impacts of alcohol compared to their younger counterparts.

    The goal of this study is to evaluate whether coping motives mediate the relationship between self-reported symptoms of social anxiety and alcohol problems across different age groups, building on previous research conducted among emerging adults. This study focuses on adult drinkers, including emerging adults (aged 18-25 years; n = 148), young adults (aged 26-39 years; n = 68), and middle-aged adults (aged 40-65 years; n = 51). All participants completed measures of social anxiety symptoms, alcohol problems, and coping motives, administered via the Web. Invariance tests using structural equation modeling suggested that among emerging adults (and to some degree middle-aged adults), coping motives mediated the positive relationship between symptoms of social anxiety and alcohol problems. Interestingly, coping motives appeared to suppress a negative relationship between social anxiety and alcohol problems in young adults. Results suggest that it is critical to consider age differences when attempting to understand the relationships between symptoms of social anxiety, alcohol problems, and coping motives.

    Studies have shown that environmental factors, such as exposure to childhood maltreatment, might shift the course of addiction. Little is known, however, about whether childhood physical neglect (PN) influences the severity of withdrawal and depressive symptoms during the detoxification period. This is a 3 weeks follow-up study. The participants were divided into 2 groups: those with a history of PN (PN+) (n=32) and those without a history of PN (PN-) (n=48). Clinical variables were assessed with the SCID-I, BDI-II, Childhood Trauma Questionnaire, Addiction Severity Index and Cocaine Selective Severity Assessment. Depressive symptom assessments were repeated at three time points. Withdrawal symptom assessments were repeated at five different points following detoxification. A repeated measures analysis of covariance indicated that the PN+ group exhibited a significantly lower reduction in the severity of withdrawal symptoms compared to the PN- group (p<0.05). Post hoc analyses showed that after 12 days of treatment, the severity of withdrawal symptoms in the PN+ group did not decrease in the same level as was observed in the PN- group. Moreover, a strong correlation was found between the severity of depression and the intensity of the abstinence symptoms during treatment. Patients who reported more depressive symptoms also exhibited more severe withdrawal symptoms. The ASI-6 indicated higher severity problems related to alcohol and psychiatric disorders in the PN+ groups. Our data support the role of childhood PN in the contingencies of the detoxification process of crack cocaine-dependent women.

  20. Ecological Momentary Assessment of Acute Alcohol Use Disorder Symptoms: Associations With Mood, Motives, and Use on Planned Drinking Days

    Several theories posit that alcohol is consumed both in relation to one’s mood and in relation to different motives for drinking. However, there are mixed findings regarding the role of mood and motives in predicting drinking. Ecological momentary assessment (EMA) methods provide an opportunity to evaluate near real-time changes in mood and motives within individuals to predict alcohol use. In addition, endorsement of criteria of an alcohol use disorder (AUD) may also be sensitive to changes within subjects. The current study used EMA with 74 moderate drinkers who responded to fixed and random mood, motive, alcohol use, and AUD criteria prompts over a 21-day assessment period. A temporal pattern of daytime mood, evening drinking motivation, and nighttime alcohol use and acute AUD symptoms on planned drinking days was modeled to examine how these associations unfold throughout the day. The results suggest considerable heterogeneity in drinking motivation across drinking days. Additionally, an affect regulation model of drinking to cope with negative mood was observed. Specifically, on planned drinking days, the temporal association between daytime negative mood and the experience of acute AUD symptoms was mediated via coping motives and alcohol use. The current study found that motives are dynamic, and that changes in motives may predict differential drinking patterns across days. Further, the study provides evidence that emotion-regulation-driven alcohol involvement may need to be examined at the event level to fully capture the ebb and flow of negative affect motivated drinking.

    The Z-category hypnotics are promoted for their relative safety. However, this view is challenged by the emerging clinical evidence in the form of zolpidem related intoxication delirium and seizures, and dependence and complicated withdrawal. We report the case of a zolpidem-naive alcohol-dependent inpatient that, while undergoing alcohol de-addiction, was prescribed zolpidem for insomnia and developed delirium during taper-off. He was successfully detoxified for alcohol, treated for delirium and put on disulfiram prophylaxis. The case highlights the need for being cautious while using zolpidem for insomnia in alcohol dependent subjects. PMID:22144786

    This study examined whether urgency, a disposition to rash action under conditions of strong emotion, moderates associations between internalizing symptoms and alcohol use and related expectancies. Data from the Camden Youth Development Study, a longitudinal, community-based study of early adolescents (N = 144, mean age at intake = 11.9 years; 65% Hispanic, 30% African-American; 50% male), were used. Self-report questionnaire measures of depressive symptoms, social and generalized anxiety symptoms, urgency, alcohol use, and alcohol expectancies were used. Mixed models were used to examine the effects of internalizing symptoms, urgency, and their interaction on alcohol use and expectancy trajectories over time. Depressive symptoms interacted with urgency such that youth with high levels of both tended to have elevated levels of global positive alcohol expectancies. Social anxiety symptoms interacted with urgency to be associated with increasing levels of social behavior alcohol expectancies such that youth with high levels of both tended to experience particular increases in these expectancies over time. Generalized anxiety was not found to be associated with alcohol-related constructs. Therefore, high levels of urgency combine with depressive and social anxiety symptoms to be associated with particularly increased risk for alcohol expectancies that are associated with later alcohol use and problems, indicating particular risk for youth with these combinations of personality traits and psychopathology symptoms.

    Objective College matriculation begins a period of transition into adulthood, one that is marked by new freedoms and responsibilities. This transition also is marked by an escalation in heavy drinking and other drug use, and a variety of use-related negative consequences. Trauma and symptoms of posttraumatic stress disorder (PTSD) may affect alcohol and drug problems, and thus may be a point of intervention. Yet no studies have examined trauma, PTSD, and alcohol and drug problem associations during this developmental period. The present study provides such an examination. Method Matriculating college students (N=997) completed surveys in September (T1) and at five subsequent time points (T2-T6) over their first year of college. With latent growth analysis, trajectories of alcohol and drug-related consequences were modeled to examine how trauma (No Criterion A Trauma, Criterion A Only, No PTSD symptoms) and PTSD (partial or full) symptom status predicted these trajectories. Results Results showed substantial risk for alcohol- and other drug-related negative consequences that is conferred by the presence of PTSD at matriculation. Those with both partial and full PTSD started the year with more alcohol and drug consequences. These individuals showed a steeper decrease in consequences in the first semester, which leveled off as the year progressed. Both alcohol and drug consequences remained higher for those in the PTSD group throughout the academic year. Hyper-arousal symptoms showed unique effects on substance consequence trajectories. Risk patterns were consistent for both partial and full PTSD symptom presentations. Trajectories did not vary by gender. Conclusions Interventions that offer support and resources to students entering college with PTSD may help to ameliorate problem substance use and may ultimately facilitate a stronger transition into college and beyond.

    Little research has examined social development in the young adult years relative to childhood and adolescence. This study tested the hypothesized pathways of the social development model (SDM) in young adulthood for predicting symptoms of alcohol use disorder (AUD) and positive functioning at age 30. A longitudinal panel study originally drawn from Seattle, Washington, elementary schools was examined. The sample included 808 participants with high retention and was gender balanced and ethnically diverse. Analyses focused on ages 21, 27, and 30. SDM constructs were assessed with self-reports of past-year behavior and combined multiple life domains. AUD symptoms corresponding to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (American Psychiatric Association, 1994) criteria were assessed using the Diagnostic Interview Schedule. Positive functioning combined measures of constructive engagement in work and school, civic engagement, physical exercise, and lack of depressive symptoms. The study found that AUD symptoms were moderately stable from age 21 to 30; however, developmental pathways hypothesized by the SDM at age 27 played a significant role in partially mediating this association. Alcohol-specific factors were key mediating mechanisms, whereas prosocial factors played little role. Conversely, prosocial factors had an important role in predicting positive functioning at age 30, whereas there were no significant pathways involving alcohol-specific factors. Findings suggest that age 27 is not too late for interventions targeting adult social development to help diminish alcohol use disorder symptoms by age 30. Alcohol-specific factors such as reducing perceived opportunities or rewards for heavy alcohol use or challenging beliefs accepting of drunkenness are likely to be key ingredients of effective adult interventions.

    Prior research has indicated that childhood sexual abuse (CSA), alcohol use, and posttraumatic stress disorder (PTSD) symptoms are important risk factors for adult sexual assault (ASA). A notable limitation of this prior work, however, is that it has almost exclusively focused on heterosexual women. The present study sought to remedy this by examining the extent to which CSA, alcohol use, and PTSD symptoms related to ASA among lesbians (n = 122) and gay men (n = 117). Using structural equation modeling, we found that alcohol use was the best predictor of ASA among lesbians whereas CSA was the best predictor of ASA among gay men. These results suggest that certain risk factors may be differentially related to ASA among groups with different sexual orientations. Such findings deepen our current understanding of ASA and offer important directions for reducing the risk of ASA for lesbian and gay individuals.

    Background The U.S.-Mexico border displays elevated rates of hazardous alcohol and drug use. Whether the co-occurrence of alcohol and drug use and disorders is also high in the border area is unknown. Methods Data are from the U.S.-Mexico Study on Alcohol and Related Conditions, a cross-sectional survey of randomly selected respondents interviewed from 2011–2013. Participants included 1,690 Mexican Americans from Texas (572 in an off-border city and 1,118 from 3 border cities) and 1,293 Mexicans from Nuevo Leon and Tamaulipas (415 in an off-border city and 878 from 3 Mexican cities bordering Texas) who reported drinking in the last 12 months. Participants were interviewed regarding the prevalence of and risk factors for: a) co-occurring hazardous alcohol use (5+/4+ at least monthly) and drug use (medical and illicit), and b) co-occurring presence of a DSM-5 alcohol use disorder (AUD) and 2 symptoms (hazardous use and quit/control) of drug use disorders (DUD symptoms). Results Co-occurring hazardous alcohol and drug use was more common in the U.S. border cities (14.7%) than off-border (7.2%), but similar for Mexican border (1.2%) and off-border (1.4%) cities. Co-occurrence of AUD and DUD symptoms was likewise more common at the U.S. border (6.8%) than off-border (3.3%), as well as at the Mexican border (1.3%), compared to off-border (0.6%), but not statistically significant for Mexico. In models adjusting for demographics, mobility factors and exposure to the U.S. culture, border residence in both countries related to a nearly two-fold increase in prevalence ratios (PR) of co-occurring AUD and DUD symptoms (PR=1.97, 95%CI=1.36–2.85). Conclusions Increased rates of co-occurring alcohol and drug use disorders suggest an added negative impact on already difficult conditions of the border population. PMID:25833029

    Alcoholic patients who have undergone multiple detoxifications/relapses show altered processing of emotional signals. We performed functional magnetic resonance imaging during performance of implicit and explicit versions of a task in which subjects were presented with morphs of fearful facial emotional expressions. Participants were abstaining, multiply detoxified (MDTx; n=12) or singly detoxified patients (SDTx; n=17), and social drinker controls (n=31). Alcoholic patients were less able than controls to recognize fearful expressions, and showed lower activation in prefrontal areas, including orbitofrontal cortex and insula, which mediate emotional processing. The decrease in activation was greater in MDTx patients who also showed decreased connectivity between insula and prefrontal areas, and between amygdala and globus pallidus. In the explicit condition, the strength of connectivity between insula and areas involved in regulation of emotion (inferior frontal cortex and frontal pole) was negatively correlated with both the number of detoxifications and dependency (measured by the severity of alcohol dependency (SADQ) and control over drinking score (Impaired Control questionnaire, ICQ)). In contrast, increased connectivity was found between insula and the colliculus neuronal cluster, and between amygdala and stria terminalis bed nucleus. In the implicit condition, number of detoxifications and ICQ score correlated positively with connectivity between amygdala and prefrontal cortical areas involved in attentional and executive processes. Repeated episodes of detoxification from alcohol are associated with altered function both in fear perception pathways and in cortical modulation of emotions. Such changes may confer increased sensitivity to emotional stress and impaired social competence, contributing to relapse.

    Background Literature has demonstrated the adaptive function of identity development and parenting toward manifestation of problem behaviors in adolescence. These dimensions act on both internalizing and externalizing symptoms. Methods The objective is to investigate the relationship between identity status, parenting, and adolescent problems, which may manifest through internalized (phobias, obsessions, depression, eating disorders, entropy) and externalized modes (alcohol use and school discomfort). The research involved 198 Italian students (104 males and 94 females) in the 4th year (mean =16.94 years, standard deviation =0.35) and 5th year (mean =17.94 years, standard deviation =0.43) of senior secondary schools, who live in Caltanissetta, a town located in Sicily, Italy. The research lasted for 1 school year. The general group consisted of 225 students with a mortality rate of 12%. They completed an anamnestic questionnaire to provide 1) basic information, 2) alcohol consumption attitude in the past 30 days, and 3) their beliefs about alcohol; the “Ego Identity Process Questionnaire” to investigate identity development; the “Parental Bonding Instrument” to measure the perception of parenting during childhood; and the “Constraints of Mind” to value the presence of internalizing symptoms. Results Data show that identity status influences alcohol consumption. Low-profile identity and excessive maternal control affect the relational dependence and the tendency to perfectionism in adolescents. Among the predictors of alcohol use, there are socioeconomic status, parental control, and the presence of internalizing symptoms. Conclusion Family is the favored context of learning beliefs, patterns, and values that affect the broader regulatory social environment, and for this reason, it is considered the privileged context on which to intervene to reduce the adolescents’ behavior problems. This deviance could be an external manifestation of the difficulty

    This study prospectively examines the association between social and generalized anxiety symptoms and alcohol and cigarette use in early adolescence and how injunctive (perceived peer approval of use) and descriptive (perceived peer use) norms may moderate the association. Sex differences were also examined. Data were taken from a longitudinal study investigating problem behavior and adolescent substance use. The community sample (N=387) was assessed annually, and data from the first two waves of assessment were used for this study. Early adolescents were between the ages of 11 and 13 at the first assessment (mean age=11.05, SD=0.55, 55% female). Peer norms moderated the association between both social and generalized anxiety symptoms and the likelihood of alcohol and cigarette use for girls, but not for boys. Specifically, girls with elevated levels of generalized anxiety symptoms were at risk for use when perceived peer use was low, and protected from use when perceived peer use was high. Girls with elevated levels of social anxiety symptoms were at risk for use when perceived peer approval of use was high, and protected from use when perceived peer approval of use was low. Past studies have found inconsistent support for an association between anxiety and adolescent substance use, and our findings provide some clarity regarding for whom and when anxiety operates as a risk/protective factor. Social context and sex are critical for understanding the role of different forms of anxiety in the etiology of adolescent alcohol and cigarette use. PMID:23380488

    The previously published randomized controlled trial, EARLY, tested the efficacy of a Motivational Interviewing (MI) plus Feedback condition against a Video Information (VI) condition and an Informational Brochure (IB) condition in reducing drinking and/or increasing contraception effectiveness, and found that drinking and rates of effective contraception improved in all conditions. In this reanalysis of the data from EARLY, potential moderating effects of depressive, global distress, and anxiety symptoms in response to the 3 brief interventions to reduce alcohol exposed pregnancy risk were examined. Women with higher levels of depression at baseline reported greater improvements in the MI plus Feedback condition versus the VI and IB conditions with depression moderating both drinking and contraceptive effectiveness. Global distress moderated only drinking behavior in the MI plus Feedback but not other groups and anxiety was not a moderator of outcome in any of the intervention groups. Depressed or distressed women at risk for AEP may benefit from an AEP risk reduction intervention that incorporates interaction with a treatment provider versus educational information provided via video or written materials.

    Unhealthy drinking is a significant problem contributing to poor health and performance of military personnel. The Iowa Army National Guard and the Iowa Department of Public Health have collaborated with the Substance Abuse and Mental Health Administration to better identify unhealthy substance use via Screening, Brief Intervention, and Referral to Treatment program (SBIRT). Yet, little research has been conducted on the Guard's use of SBIRT. This study examined depression, age, deployment status, and sex as factors contributing to unhealthy drinking. Of the Guardsmen who took part in SBIRT, 3.7% (n=75) met the criteria for unhealthy drinking and 3.9% (n=78) had some level of depression. The overall multivariate model significantly predicted unhealthy drinking (χ(2)(5)=41.41, p<0.001) with age moderating the association of depressive symptoms and unhealthy alcohol (Wald χ(2)(1)=7.16, p=0.007). These findings add to the existing understanding of factors contributing to unhealthy drinking suggesting the association between the presence of depression and unhealthy drinking depends on age of the Guradsman. This age and depression interaction may be an important diagnostic feature to consider for unhealthy drinking in the Guard. Furthermore, previous research on the general military population finds similar percentages, providing support for SBIRT as an effective screening tool in the Guard.

    Background Activation of the kynurenine pathway of tryptophan metabolism results in increased production of potentially depressogenic tryptophan catabolites and a reduction in tryptophan availability for serotonin synthesis. Since alcohol consumption affects tryptophan metabolism and disposition, we determined serum levels of kynurenine, tryptophan and the kynurenine/tryptophan ratio (KT ratio) in alcohol-use disorder (AUD) patients and compared their levels considering abstinence duration, AUD severity and comorbid depression. Methods The study sample included 169 AUD inpatients from eight alcohol treatment facilities in Kathmandu, Nepal. The Composite International Diagnostic Interview was administered to generate the AUD diagnosis. The Alcohol Use Disorder Identification Test (AUDIT) captured AUD severity and patterns of alcohol use. The Hopkins Symptom Checklist-25 was used to reveal current depressive symptoms. Serum kynurenine and tryptophan levels were determined by high-performance liquid chromatography and tryptophan degradation was measured by KT ratio (kynurenine/tryptophan × 103). Results Patients with above average AUDIT scores had higher mean serum levels of kynurenine (2.1μM±0.7 vs 1.8 μM ±0.6, p= 0.006) and KT ratios (48.6±17.6 vs 40.4±14.3, p=0.002) than those with below average scores. Patients with current depressive symptoms had higher mean tryptophan concentrations (49.9 μM ±13 vs 45.7 μM±14.1, p= 0.047) and lower KT ratios (41.4 μM ±14 vs 47.5 μM ±17.6, p=0.028) compared to patients whose reported depressive symptoms were below the standard cut-off. Higher tryptophan levels and lower KT ratios in the depressed group was specific to patients with longer abstinence and higher AUD severity. Conclusions Depression-related deregulation in tryptophan metabolism was found to depend on length of abstinence and on AUD severity. Together, results suggest that in AUD populations, peripheral tryptophan metabolism is subject to interactions

    Veterans returning from Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF) have been found to be at increased risk for post-traumatic stress disorder (PTSD) and alcohol use disorders, leading to negative mental health-related quality of life (MHRQoL). The current study examined the unique impact of alcohol consumption levels versus alcohol-related consequences on the relationship between PTSD symptoms and MHRQoL in a sample of OEF/OIF combat veterans (N = 205, median age 29, 95% men). Mediation analyses indicated that the effect of PTSD symptoms on MHRQoL was explained only by alcohol-related consequences and not by alcohol consumption. Findings highlight the importance of including alcohol-related consequences in clinical assessment and intervention programs for OEF/OIF veterans. Additionally, this study enhances knowledge regarding the underlying mechanisms of functional impairment related to PTSD and alcohol use disorders.

  3. CHRONIC ALCOHOL NEUROADAPTATION AND STRESS CONTRIBUTE TO SUSCEPTIBILITY FOR ALCOHOL CRAVING AND RELAPSE

    2010-01-01

    Alcoholism is a chronic relapsing disorder. Major characteristics observed in alcoholics during an initial period of alcohol abstinence are altered physiological functions and a negative emotional state. Evidence suggests that a persistent, cumulative adaptation involving a kindling/allostasis-like process occurs during the course of repeated chronic alcohol exposures that is critical for the negative symptoms observed during alcohol withdrawal. Basic studies have provided evidence for specific neurotransmitters within identified brain sites being responsible for the negative emotion induced by the persistent cumulative adaptation following intermittent-alcohol exposures. After an extended period of abstinence, the cumulative alcohol adaptation increases susceptibility to stress- and alcohol cue-induced negative symptoms and alcohol seeking, both of which can facilitate excessive ingestion of alcohol. In the alcoholic, stressful imagery and alcohol cues alter physiological responses, enhance negative emotion, and induce craving. Brain fMRI imaging following stress and alcohol cues has documented neural changes in specific brain regions of alcoholics not observed in social drinkers. Such altered activity in brain of abstinent alcoholics to stress and alcohol cues is consistent with a continuing ethanol adaptation being responsible. Therapies in alcoholics found to block responses to stress and alcohol cues would presumably be potential treatments by which susceptibility for continued alcohol abuse can be reduced. By continuing to define the neurobiological basis of the sustained alcohol adaptation critical for the increased susceptibility of alcoholics to stress and alcohol cues that facilitate craving, a new era is expected to evolve in which the high rate of relapse in alcoholism is minimized. 250 PMID:20951730

    Exploring the relationships among PTSD, alcohol misuse, and women's use of intimate partner violence (IPV) is vital to develop our understanding of the etiologies of women's use of IPV, which can serve to maximize intervention efforts for women. This study examined the extent to which posttraumatic stress disorder (PTSD) symptom clusters are directly and indirectly related to women's use of IPV through pathways involving alcohol misuse while controlling for severity of women's IPV victimization. The sample was comprised of substance using, low socioeconomic status community women (n = 143) currently experiencing IPV victimization. The majority of the sample was African American (n = 115, 80.42%). This sample had a mean annual household income of $14,368.68 (SD = $12,800.68) and the equivalent of a high school education (11.94 years, SD = 1.32). Path analyses indicated that the strongest statistical relationship emerged between women's use of IPV and women's IPV victimization. PTSD re-experiencing and numbing symptom severity were related to women's use of psychological, minor physical, and severe physical IPV, however these relationships were indirect through alcohol misuse. Findings lend preliminary support for the application of the self-medication hypothesis to the study of PTSD, alcohol misuse, and IPV among women. PMID:23868671

    Depressed mood often co-exists with frequent drug and alcohol use. This trial examined the feasibility of screening, recruitment, randomization and engagement of drug and alcohol users in psychological interventions for depression symptoms. A total of 50 patients involved in community drugs and alcohol treatment (CDAT) were randomly allocated to behavioral activation delivered by psychological therapists (n = 23) or to cognitive behavioral therapy based self-help introduced by CDAT workers (n = 27). We examined recruitment and engagement rates, as well as changes in depression (PHQ-9) symptoms and changes in percent days abstinent (PDA within last month) at 24 weeks follow-up. The ratio of screened to recruited participants was 4 to 1, and the randomization schedule successfully generated 2 groups with comparable characteristics. Follow-up was possible with 78% of participants post-treatment. Overall engagement in psychological interventions was low; only 42% of randomized participants attended at least 1 therapy session. Patients offered therapy appointments co-located in CDAT clinics were more likely to engage with treatment (odds ratio = 7.14, p = .04) compared to those offered appointments in community psychological care clinics. Intention-to-treat analyses indicated no significant between-group differences at follow-up in mean PHQ-9 change scores (p = .59) or in PDA (p = .08). Overall, it was feasible to conduct a pragmatic trial within busy CDAT services, maximizing external validity of study results. Moderate and comparable improvements in depression symptoms over time were observed for participants in both treatment groups.

  12. Assessment of affective and somatic signs of ethanol withdrawal in C57BL/6J mice using a short term ethanol treatment

    PubMed Central

    Perez, EE; De Biasi, M

    2015-01-01

    Alcohol is one of the most prevalent addictive substances in the world. Withdrawal symptoms result from abrupt cessation of alcohol consumption in habitual drinkers. The emergence of both affective and physical symptoms produces a state that promotes relapse. Mice provide a preclinical model that could be used to study alcohol dependence and withdrawal while controlling for both genetic and environmental variables. The use of a liquid ethanol diet offers a reliable method for the induction of alcohol dependence in mice, but this approach is impractical when conducting high throughput pharmacological screens or when comparing multiple strains of genetically engineered mice. The goal of this study was to compare withdrawal associated behaviors in mice chronically treated with a liquid ethanol diet vs. mice treated with a short-term ethanol treatment that consisted of daily ethanol injections containing the alcohol dehydrogenase inhibitor, 4-methylpyrazole. Twenty-four hours after ethanol treatment, mice were tested in the open field arena, the elevated plus maze, the marble burying test or for changes in somatic signs during spontaneous ethanol withdrawal. Anxiety-like and compulsive-like behavior, as well as physical signs, were all significantly elevated in mice undergoing withdrawal, regardless of the route of ethanol administration. Therefore, a short-term ethanol treatment can be utilized as a screening tool for testing genetic and pharmacological agents before investing in a more time consuming ethanol treatment.

    Michelsen, H; Bildt, C

    2003-01-01

    Background: Psychiatric epidemiology has revealed a number of associations between gender, socioeconomic status, and psychiatric disorders. Aims: To examine psychosocial conditions on and off the job in relation to psychological ill health. Methods: Longitudinal design with 24 year follow up of employed persons (190 women, 177 men). Interview and questionnaire data on work and leisure conditions were collected in 1969 and 1993. Risk analyses were performed in relation to three outcomes in 1993: depression within the preceding 12 months, impaired psychological wellbeing, and heavy alcohol use. Results: Thirteen per cent of the women and 11% of the men showed symptoms of depression, 21% and 22% had impaired psychological wellbeing, and 7% and 15% respectively were heavy alcohol users. Dissatisfaction with the quality (women) or quantity (men) of social contacts 24 years earlier was a significant risk factor for depression. Dissatisfaction with the quality of social contacts was also associated with impaired psychological wellbeing (among women), and dissatisfaction with leisure time activities was associated with heavy alcohol use (among men). Frequent overtime work 24 years earlier was associated with heavy alcohol use among women. Cross sectional analyses also showed associations between psychological ill health and some work related factors (mentally demanding work and lack of job pride). Conclusions: Perceived inadequacies in social contacts, and practical obstacles to social relationships are viewed as risk factors for depression. In this longitudinal study, work related factors, including mental demands and time pressure, do not appear sufficiently associated with psychological ill health. PMID:12819282

    PubMed

    Müller-Vahl, K R; Kolbe, H; Dengler, R

    1997-12-01

    Gilles de la Tourette syndrome (TS) is a neuropsychiatric spectrum disorder of unknown etiology. While several studies have provided evidence that nicotine causes an improvement, only anecdotal reports suggest that alcohol and marijuana influence the symptomatology. Using a structured interview, we questioned a larger group of patients with Tourette syndrome (n = 47) about the use of nicotine, alcohol, and marijuana and their subjective experiences. Of 28 smoking patients only 2 (7%) reported a tic reduction when smoking. Of 35 patients drinking alcohol 24 (69%) noted an improvement. Thirteen patients reported the use of marijuana, of whom 11 (85%) noted a marked improvement. Our results provided strong evidence that the use of both alcohol and marijuana causes much more improvement in TS than nicotine smoking. We suggest that marijuana influences an assumed interaction between cannabinoid and dopamine receptors and, by this, influences the dopaminergic processes in basal ganglia and motor activity.

    We present the case of a non-alcoholic man, who, following severe malnutrition, presented with dysphagia that necessitated gastrostomy tube placement. The patient subsequently developed encephalopathy, at which point thiamine deficiency was suspected and thiamine supplementation initiated. The encephalopathy and the dysphagia resolved, but the patient was left with a dense amnestic deficit consistent with Korsakoff syndrome. MRI at the time of the encephalopathy revealed lesions consistent with Wernicke-Korsakoff syndrome. This case represents a remarkable example of Wernicke-Korsakoff syndrome that for a prolonged time period had as its sole manifestation severe dysphagia. To our knowledge, there is only one similar case reported in the literature. This case serves to alert neurologists that isolated dysphagia may be the presenting symptom of this classic neurological syndrome even in the absence of alcoholism.

    The present study evaluated the role of pecan nut (Carya illinoensis) shells aqueous extract (AE) against oxidative damage induced by cigarette smoke exposure (CSE) and behavioral parameters of smoking withdrawal. Mice were passively exposed to cigarette smoke for 3 weeks (6, 10, and 14 cigarettes/day) and orally treated with AE (25 g/L). CSE induced lipid peroxidation in brain and red blood cells (RBC), increased catalase (CAT) activity in RBC, and decreased plasma ascorbic acid levels. AE prevented oxidative damage and increased antioxidant defenses of mice exposed to cigarette smoke. In addition, AE reduced the locomotor activity and anxiety symptoms induced by smoking withdrawal, and these behavioral parameters showed a positive correlation with RBC lipid peroxidation. Our results showed the beneficial effects of this by-product of the pecan industry, indicating its usefulness in smoking cessation.

    Despite the prevalence of depression and alcohol use among HIV-infected individuals, few studies have examined their association together in relation to nonadherence to antiretroviral therapy in sub-Saharan Africa. This study examined depressive symptoms, alcohol use, and other psychosocial factors (stigma, demographic characteristics) in relation to nonadherence to antiretroviral therapy among clinic-attending, HIV-infected individuals in South Africa (n = 101). Nonadherence was assessed using event-level measurement (missed doses over the past weekend). Multivariable logistic regression analyses revealed that only alcohol use, over and above depressive symptoms and education level, was associated with antiretroviral therapy nonadherence(AOR = 1.15; 95%CI = 1.02-1.29; p < .05). Findings point to the independent association of alcohol use and nonadherence to antiretroviral therapy above and beyond depressive symptoms.

    We present a descriptive, retrospective study of initial symptoms, comorbidity, and alcohol withdrawal in 73 alcoholic patients with subsequent Korsakoff syndrome. In 25/73 (35%) of the patients the classic triad of Wernicke's encephalopathy with ocular symptoms, ataxia and confusion, was found. In at least 6/35 (17%) of the initial deliria (95% confidence interval: 10-25%) we observed no other underlying causes, thus excluding other somatic causes, medication, (recent) alcohol withdrawal, or intoxication. We suggest that these deliria may have been representing Wernicke's encephalopathy. A high frequency (15%) of diabetics may reflect a contributing factor of diabetes mellitus in the evolution of the Wernicke-Korsakoff syndrome.

Biochemical parameters of hepatic function and severity of withdrawal state were also assessed. Significantly elevated values of plasma HGH were found in alcoholics as a group. Nineteen percent and eight percent of the patient had elevated serum PRL and HGH levels respectively. Evidence of advanced liver disease was scant and withdrawal symptoms were by and large mild.

    Alcohol use disorders (AUD) are defined as alcohol abuse and alcohol dependence, which create large problems both for society and for the drinkers themselves. To date, no therapeutic can effectively solve these problems. Understanding the underlying mechanisms leading to AUD is critically important for developing effective and safe pharmacological therapies. Benzodiazepines (BZs) are used to reduce the symptoms of alcohol withdrawal syndrome. However, frequent use of BZs causes cross-tolerance, dependence, and cross-addiction to alcohol. The FDA-approved naltrexone and acamprosate have shown mixed results in clinical trials. Naltrexone is effective to treat alcohol dependence (decreased length and frequency of drinking bouts), but its severe side effects, including withdrawal symptoms, are difficult to overcome.

    Alcohol use disorders (AUD) are defined as alcohol abuse and alcohol dependence, which create large problems both for society and for the drinkers themselves. To date, no therapeutic can effectively solve these problems. Understanding the underlying mechanisms leading to AUD is critically important for developing effective and safe pharmacological therapies. Benzodiazepines (BZs) are used to reduce the symptoms of alcohol withdrawal syndrome. However, frequent use of BZs causes cross-tolerance, dependence, and cross-addiction to alcohol. The FDA-approved naltrexone and acamprosate have shown mixed results in clinical trials. Naltrexone is effective to treat alcohol dependence (decreased length and frequency of drinking bouts), but its severe side effects, including withdrawal symptoms, are difficult to overcome. Acamprosate showed efficacy for treating alcohol dependence in European trials, but two large US trials have failed to confirm the efficacy.

    The negative reinforcement model of addiction posits that individuals may use alcohol to reduce with negative affective (NA) distress. The current study investigated the mediating effect of daily NA on the relationship between daily PTSD symptoms and same-day and next-day alcohol involvement (consumption and desire to drink) in a sample of 54 non-treatment-seeking female rape victims who completed 14 days of interactive voice response assessment. The moderating effect of lifetime alcohol use disorder diagnosis (AUD) on daily relationships was also examined. Multilevel models suggested that NA mediated the relationship between PTSD and same-day, but not next-day alcohol involvement. NA was greater on days characterized by more severe PTSD symptoms, and alcohol consumption and desire to drink were greater on days characterized by higher NA. Further, daily PTSD symptoms and NA were more strongly associated with same-day (but not next-day) alcohol consumption and desire to drink for women with an AUD than without. Results suggest that NA plays an important role in female rape victims’ daily alcohol use. Differences between women with and without an AUD indicate the need for treatment matching to sub-types of female rape victims. PMID:24731112

  8. Alcohol hangover: mechanisms and mediators.

    PubMed

    1998-01-01

    Hangovers are a frequent, though unpleasant, experience among people who drink to intoxication. Despite the prevalence of hangovers, however, this condition is not well understood scientifically. Multiple possible contributors to the hangover state have been investigated, and researchers have produced evidence that alcohol can directly promote hangover symptoms through its effects on urine production, the gastrointestinal tract, blood sugar concentrations, sleep patterns, and biological rhythms. In addition, researchers postulate that effects related to alcohol's absence after a drinking bout (i.e., withdrawal), alcohol metabolism, and other factors (e.g., biologically active, nonalcohol compounds in beverages; the use of other drugs; certain personality traits; and a family history of alcoholism) also may contribute to the hangover condition. Few of the treatments commonly described for hangover have undergone scientific evaluation.

    Research has indicated that Hispanics have high rates of heavy drinking and depressive symptoms during late adolescence. The purpose of this study was to test a bicultural transaction model composed of two enthnocultural orientations (acculturation and enculturation); and stressful cultural transactions with both the U.S. culture (perceived ethnic discrimination) and Hispanic culture (perceived intragroup marginalization) to predict alcohol use severity and depressive symptoms among a sample of 129 (men=39, women=90) late adolescent Hispanics (ages 18-21) enrolled in college. Results from a path analysis indicated that the model accounted for 18.2% of the variance in alcohol use severity and 24.3% of the variance in depressive symptoms. None of the acculturation or enculturation domains had statistically significant direct effects with alcohol use severity or depressive symptoms. However, higher reports of ethnic discrimination were associated with higher reports of alcohol use severity and depressive symptoms. Similarly, higher reports of intragroup marginalization were associated with higher depressive symptoms. Further, both ethnic discrimination and intragroup marginalization functioned as mediators of multiple domains of acculturation and enculturation. These findings highlight the need to consider the indirect effects of enthnocultural orientations in relation to health-related outcomes.

    The aim of this study was to examine the association between cigarette smoking, alcohol consumption and depressive symptoms among adolescents, with a particular focus on gender differences. A total of 19,578 middle and high school students in Chongqing Province were surveyed. Self-reported cigarette smoking, alcohol consumption, depressive symptoms, and family- and school-related factors were assessed. A total of 8.8% adolescents reported smoking cigarettes. Tobacco use by boys (16.5%) was significantly higher than by girls (1.9%). Approximately 23.5% of adolescents reported alcohol consumption. Consumption in boys (31.5%) was significantly higher than in girls (16.2%). Depressive symptoms were prevalent in 9.1% of the sample. Girls reported significantly more symptoms (10.4%) than boys (7.7%). Multiple logistic regression analyses showed that the association between alcohol consumption and depressive symptoms was stronger among girls (AOR = 2.1, 95% CI = 1.8–2.5) than boys (AOR = 1.7, 95% CI = 1.4–2.1). A significant association (AOR = 2.3, 95% CI = 1.6–3.4) between cigarette smoking and depressive symptoms was revealed in girls only. The significant gender differences found above may provide a basis for the early identification of individuals at high risk for depression. PMID:26639938

    Few studies have described movement disorders as withdrawal symptoms during psychostimulant detoxification. Although dystonia has been reported as an uncommon adverse effect of methylphenidate treatment, it has not been described in the context of methylphenidate withdrawal. We report a case of dystonia as the main withdrawal symptom in a methylphenidate-dependent adult participating in an inpatient methylphenidate detoxification program. Although movement disorders such as dystonia are very rare adverse effects of methylphenidate withdrawal, practitioners need to be alert to this risk in order to initiate appropriate treatment.

    This study explored differences in the factor structure of depressive symptoms in patients with and without alcohol abuse, and differences in the severity of depressive symptoms between the two groups. In a sample of 358 patients without alcohol problems and 167 patients with comorbid alcohol problems, confirmatory factor analysis revealed that the same factor structures, Beck et al.'s two-factor Somatic Affective-Cognitive (SA-C) model, and Buckley et al.'s three-factor Cognitive-Affective- Somatic (C-A-S) model, demonstrated the best fit to the data in both groups. The SA-C model was preferred due to its more parsimonious nature. Evidence for strict measurement invariance across the two groups for the SA-C model was found. MIMIC (multiple-indicator-multiple-cause) modeling showed that the level of depressive symptoms was found to be highest on both factors in the group with comorbid alcohol problems. The magnitude of the differences in latent mean scores suggested a moderate difference in the level of depressive symptoms between the two groups. It is argued that patients with comorbid depression and alcohol abuse should be offered parallel and adequate treatment for both conditions.

    Objective This study examined the impact of coping motives for cannabis and alcohol use on the relation between social anxiety/depressive symptoms and severity of substance use for alcohol, tobacco, and cannabis among treatment-seeking smokers who also use cannabis and alcohol. Methods The sample included 197 daily cigarette smokers (MAge 34.81 yrs, SD = 13.43) who reported using cannabis and alcohol. Results Hierarchical multiple regression analyses were conducted wherein separate models were constructed for each dependent variable. Among individuals with higher social anxiety, alcohol coping motives were associated with heavier drinking, and this was more pronounced among those low in depressive symptoms. Similarly, those at greater risk for nicotine dependence were anxious individuals with lower depressive symptoms who endorse coping-oriented motives for using cannabis. Further, among those with higher social anxiety, cannabis coping motives were associated with marginally greater drinking, particularly for those high in depressive symptoms. Conclusions The present findings support the perspective that among multi-substance users, the interplay between social anxiety, depressive symptoms, and coping-oriented motives for using one substance (e.g., cannabis or alcohol) may pose difficulties in refraining from other substances (e.g., tobacco). This observation highlights the importance of tailoring multi-substance treatments to specific needs of multi-users for whom single-substance interventions may be less effective. Findings also support previous work exploring the benefits of concurrently treating co-occurring substance use and lend credence to the perspective that motivation to use substances for coping reasons is of central theoretical and clinical relevance.

    The molecular mechanisms underlying the neuronal signaling changes in alcohol addiction and withdrawal are complex and multifaceted. The cortico-striatal circuit is highly implicated in these processes, and the striatum plays a significant role not only in the early stages of addiction, but in the developed-addictive state as well, including withdrawal symptoms. Transcriptional analysis is a useful method for determining changes in gene expression, however, the results do not always accurately correlate with protein levels. In this study, we employ label-free proteomic analysis to determine changes in protein expression within the striatum during chronic ethanol use and early withdrawal. The striatum, composed primarily of medium spiny GABAergic neurons, glutamatergic and dopaminergic nerve terminals and astrocytes, is relatively homogeneous for proteomic analysis. We were able to analyze more than 5000 proteins from both the dorsal (caudate and putamen) and ventral (nucleus accumbens) striatum and identified significant changes following chronic intermittent ethanol exposure and acute (8 h) withdrawal compared to ethanol naïve and ethanol exposure groups respectively. Our results showed significant changes in proteins involved in glutamate and opioid peptide signaling, and also uncovered novel pathways including mitochondrial function and lipid/cholesterol metabolism, as revealed by changes in electron transport chain proteins and RXR activation pathways. These results will be useful in the development of novel treatments for alcohol withdrawal and thereby aid in recovery from alcohol use disorder. PMID:27014007

    Background Genetic risk for alcohol dependence has been shown to overlap with genetic factors contributing to variation in dimensions of personality. Though drinking motives have been posited as important mediators of the alcohol-personality relation, the extent to which the genetic covariance between alcohol use disorder (AUD) symptoms (i.e. abuse and dependence criteria) and personality is explained by genetic factors contributing to variation in drinking motives remains unclear. Methods Using data from 2,904 young adult female twins, the phenotypic and genetic associations among personality dimensions (constraint [measured by the Multidimensional Personality Questionnaire; Tellegen, 1982], conscientiousness, neuroticism, and agreeableness [measured by the NEO-PI; Costa & McCrae, 1985]), internal drinking motives (enhancement and coping motives [measured by the Drinking Motive Questionnaire; Cooper, 1994]), and AUD symptoms were tested. Results Significant genetic associations were found between all personality measures and AUD symptoms. Coping motives showed significant genetic overlap with AUD symptoms and most personality measures, whereas enhancement motives were not significantly heritable. Adjusting for coping motives, genetic correlations between AUD symptoms and traits of neuroticism and agreeableness were no longer statistically significant. Conclusions Findings suggest that genetic variation in drinking to cope might account for a considerable proportion of the genetic covariance between specific personality dimensions and AUD symptoms.

    The increasing prescription of opioids is fueling an epidemic of addiction and overdose deaths. Morphine is a highly addictive drug characterized by a high relapse rate – even after a long period of abstinence. Serotonin (5-HT) neurotransmission participates in the development of morphine dependence, as well as the expression of morphine withdrawal. In this study, we examined the effect of blockade of 5-HT2A receptors (5-HT2ARs) on morphine-induced behavioral sensitization and withdrawal in male mice. 5-HT2AR antagonist MDL 11,939 (0.5 mg/kg, i.p.) suppressed acute morphine (5.0 mg/kg, s.c.)-induced increase in locomotor activity. Mice received morphine (10 mg/kg, s.c.) twice a day for 3 days and then drug treatment was suspended for 5 days. On day 9, a challenge dose of morphine (10 mg/kg) was administered to induce the expression of behavioral sensitization. MDL 11,939 (0.5 mg/kg, i.p.) pretreatment suppressed the expression of morphine-induced behavioral sensitization. Another cohort of mice received increasing doses of morphine over a 7-day period to induce morphine-dependence. MDL 11,939 (0.5 mg/kg, i.p.) prevented naloxone-precipitated withdrawal in morphine-dependent mice on day 7. Moreover, chronic morphine treatment increased 5-HT2AR protein level and decreased the phosphorylation of extracellular signal-regulated kinases in the prefrontal cortex. Together, these results by the first time demonstrate that 5-HT2ARs modulate opioid dependence and blockade of 5-HT2AR may represent a novel strategy for the treatment of morphine use disorders. Highlights (i) Blockade of 5-HT2A receptors suppresses the expression of morphine-induced behavioral sensitization. (ii) Blockade of 5-HT2A receptors suppresses naloxone-precipitated withdrawal in morphine-treated mice. (iii) Chronic morphine exposure induces an increase in 5-HT2A receptor protein level and a decrease in ERK protein phosphorylation in prefrontal cortex. PMID:28082900

    The literature indicates a close relationship between family dynamics and psychoactive substance use among adolescents, and multi-causality among substance use-related problems, including personal adolescent characteristics as potential influential aspects in this relationship. The purpose of this study is to investigate the role of emotional symptoms and sensation seeking as mediators in the relationship between family dynamics and alcohol and marijuana use among adolescents. The sample consisted of 571 high school students with a mean age of 14.63, who completed the Communities That Care Youth Survey in its Spanish version. We propose and test a mediation-in-serial model to identify the relationships between the study variables. The results of the mediation models indicate that, in most cases, the relationship between family dynamics and the substance use variables is meaningfully carried through the proposed mediators, first through negative emotional symptoms, and then through sensation seeking. The meaning of the mediation varies as a function of the facet of family dynamics (conflict or attachment) and the use aspect (age of onset, frequency of use, and use intention). We discuss the implications of these findings for intervention and prevention strategies.

    Epidemiological studies usually show a link between personality disorders and addictions. Dimensional models of personality, such as that of Cloninger, are able to diagnose and discriminate between transient dysfunctional behavior styles and relatively more stable traits. Certain brain areas have been proposed, as trait locations, based on their activation. This paper explores differences in personality traits among a sample of alcohol abusers (N= 95) and a control group of non-clinical population (N= 95), matched in sociodemographic variables, using the TCI-R-67 and the FrSBe-Sp. It is hypothesized that such differences are associated with frontal symptomatology. The existence of different subgroups of addicts based on certain combinations of traits is also analyzed. Results showed significant differences in two temperament traits (Novelty Seeking and Harm Avoidance) and a characterial trait (Self-Direction). We also found a correlation with a large effect size between these traits and frontal symptomatology. Cluster analysis classified the participants into several subtypes with different combinations of traits that matched diverse frontal symptomatology. Possible neurobiological explanations of these differences and their importance in the clinical practice are discussed.

    Socially withdrawn children frequently refrain from social activities in the presence of peers. The lack of social interaction in childhood may result from a variety of causes, including social fear and anxiety or a preference for solitude. From early childhood through to adolescence, socially withdrawn children are concurrently and predictively at risk for a wide range of negative adjustment outcomes, including socio-emotional difficulties (e.g., anxiety, low self-esteem, depressive symptoms, and internalizing problems), peer difficulties (e.g., rejection, victimization, poor friendship quality), and school difficulties (e.g., poor-quality teacher-child relationships, academic difficulties, school avoidance). The goals of the current review are to (a) provide some definitional, theoretical, and methodological clarity to the complex array of terms and constructs previously employed in the study of social withdrawal; (b) examine the predictors, correlates, and consequences of child and early-adolescent social withdrawal; and (c) present a developmental framework describing pathways to and from social withdrawal in childhood.

    Since the 1990s, we have suggested the concept of pre-alcoholism which encompasses patients who have drunk a great deal of alcohol leading to alcohol related problems such as health issues, domestic violence, drunken driving and black-outs. Pre-alcoholism excludes alcohol-dependent patients who have experienced continuous drinking or withdrawal symptoms. We have treated many outpatients with pre-alcoholism for several years. Our regimen demands that the patients must be abstinent for half a year at the beginning of their treatment. After half a year they can choose whether they will continue to be abstinent or they will resume drinking with the aim of reducing their total alcohol consumption. The study clarified the character of pre-alcoholism by investigation of the patients' background and re-diagnosis of the patients based on the International Classification of Diseases, 10th Revision (ICD-10). A remarkable ratio of pre-alcoholic patients was diagnosed with alcohol dependence under ICD-10. We classified pre-alcoholic patients into two groups, one diagnosed as having ICD-10-classed alcohol dependence and the other which did not fulfill the ICD-10 diagnostic criteria of alcohol dependence, and examined the therapeutic processes of the two groups. It was shown that most pre-alcoholic patients could finally take required courses of treatment by themselves without regard to diagnosis under ICD-10, even if they chose any treatment and made alcohol related mistakes on the way. Our findings suggested that pre-alcoholic patients, a portion of whom may have exhibited mild alcohol dependence, could select drinking reduction as a primary goal of treatment after a certain period of abstinence.

    Suicide is an escalating public health problem, and alcohol use has consistently been implicated in the precipitation of suicidal behavior. Alcohol abuse may lead to suicidality through disinhibition, impulsiveness and impaired judgment, but it may also be used as a means to ease the distress associated with committing an act of suicide. We reviewed evidence of the relationship between alcohol use and suicide through a search of MedLine and PsychInfo electronic databases. Multiple genetically-related intermediate phenotypes might influence the relationship between alcohol and suicide. Psychiatric disorders, including psychosis, mood disorders and anxiety disorders, as well as susceptibility to stress, might increase the risk of suicidal behavior, but may also have reciprocal influences with alcohol drinking patterns. Increased suicide risk may be heralded by social withdrawal, breakdown of social bonds, and social marginalization, which are common outcomes of untreated alcohol abuse and dependence. People with alcohol dependence or depression should be screened for other psychiatric symptoms and for suicidality. Programs for suicide prevention must take into account drinking habits and should reinforce healthy behavioral patterns. PMID:20617037

    Purpose Common advice for lower urinary tract symptoms (LUTS) of frequency, urgency and related bother includes elimination of potentially irritating beverages (coffee, tea, alcohol, and carbonated and/or artificially sweetened beverages). The purpose of this study was to determine compliance with standardized instruction to eliminate these potentially irritating beverages, whether LUTS improved after instruction, and if symptoms worsened with partial reintroduction. Design The three-phase fixed sequence design was: 1) baseline, 2) eliminate potentially irritating beverages listed above, and 3) reintroduce at 50% of baseline volume, with a washout period between each 3-day phase. We asked participants to maintain total intake volume by swapping in equal amounts of non-potentially irritating beverages (primarily water). Subjects and Setting The study sample comprised 30 community-dwelling women recruited through newspaper advertisement. Methods Quantification measures included 3-day voiding diaries and detailed beverage intake, and LUTS questionnaires completed during each phase. Results During Phase 2, we found significant reduction in potentially irritating beverages but complete elimination was rare. Despite the protocol demands, total beverage intake was not stable; mean (± standard deviation) daily total intake volume dropped by 6.2±14.9oz (p=0.03) during Phase 2. In Phase 3, the volume of total beverage intake returned to baseline, but intake of potentially irritating beverages also returned to near baseline rather than 50% as requested by protocol. Despite this incomplete adherence to study protocols, women reported reduction in symptoms of urge, inability to delay voiding, and bother during both phases (p≤0.01). The number of voids per day decreased on average by 1.3 and 0.9 voids during phases 2 and 3 respectively (p=0.002 and p=0.035). Conclusions Education to reduce potentially irritating beverages resulted in improvement in LUTS. However, eliminating

    Alcohol withdrawal seizures are part of the symptomatology of severe alcohol dependence and are believed to originate from long-term neural adaptations that counter the central nervous system depressant effects of alcohol. Upon alcohol withdrawal, however, the increased neural excitability that was adaptive in the presence of alcohol becomes counter-adaptive and produces an imbalanced hyperactive nervous system. For some individuals, the uncovering of this imbalance by alcohol abstention can be sufficient to generate a seizure. Using the Drosophila model organism, we demonstrate a central role for the BK-type Ca(2+) -activated K(+) channel gene slo in the production of alcohol withdrawal seizures.

    High Alcohol Withdrawal (HAW) and Low Alcohol Withdrawal (LAW) mice were selectively bred from a foundation population of C57BL6/J (B6) x DBA/2J (D2) F2 intercross progeny for display of intense or mild handling-induced withdrawal convulsions, respectively, following a single injection of a hypnotic dose of ethanol (alcohol; 4 g/kg). The HAW line had significantly greater alcohol withdrawal severity scores compared to the LAW line after only a single generation of selection; the magnitude of the line difference was 8-fold by the fourth selected generation. We tested these lines for severity of withdrawal convulsions following the benzodiazepine, diazepam; the gaseous anesthetic, nitrous oxide; the imidazopyridine, zolpidem and the barbiturate, pentobarbital. In all cases, HAW mice had significantly greater withdrawal severity than mice of the LAW line. These results indicate that some genes influencing withdrawal convulsion severity following ethanol also affect withdrawal from other CNS depressants. D2 mice are more sensitive to a variety of convulsants than B6 mice (and have more severe withdrawal convulsions). We, therefore, tested separate groups of mice of both selectively bred lines for threshold sensitivity to pentylenetetrazol (PTZ), N-methyl-D-aspartate (NMDA) and kainic acid (KA). No line differences were detected. These results indicate that genes influencing severity of withdrawal from several depressant drugs are largely different from those affecting susceptibility to GABAergic or glutamatergic convulsants.

    Several studies examining alcohol use and depression in youth have focused on documenting prevalence of overlap, or temporal ordering in longitudinal samples. Fewer studies have examined pathways connecting alcohol use and depression over time. This study examined gender differences between depression and alcohol use across adolescence while examining peer and family pathways as possible mediators of effects. Data was collected longitudinally from 593 families from three urban public middle schools in the United States. Participants were recruited in 6th grade and followed through 9th grade. We examined gender differences using a nested model comparison approach. Results indicated the association between depression and alcohol use differs by gender. For males, depression and alcohol use were independent across adolescence, and no significant indirect pathways were observed. For females, bidirectional effects were found between alcohol use and depression, as well as an indirect effect from depression to alcohol use via peer deviance.

    Context • Nonsteroidal, anti-inflammatory drugs effectively relieve osteoarthritis (OA) symptoms but also induce adverse effects (AEs) that limit their long-term use, which drives a search for safer treatments. D-002, a mixture of beeswax alcohols, and D-003, a mixture of sugarcane wax acids, have been effective in experimental and clinical studies for patients with OA. Objective • The study intended to investigate the effects on OA symptoms of a combined therapy using D-002 and D-003 (D-002/D-003), which were administered for 6 wk. Design • The study was a randomized, double-blind, placebo-controlled trial. Setting • The study was conducted at the Surgical Medical Research Center in Havana, Cuba. Participants • Participants were patients with mild-to-moderate OA. Intervention • Participants were randomly assigned to 1 of 4 groups-(1) a control group, which received a placebo; (2) the D-002 group (intervention group), which received 50 mg/d of D-002; (3) the D-003 group (intervention group), which received 10 mg/d of D-003; or (4) the D-002/D-003 group (intervention group), which received a combined therapy of 50 mg/d of D-002 plus 10 mg/d of D-003. The control group received tablets that were indistinguishable in appearance from the D-002 and D-003 tablets and had a similar composition, except that the active ingredients were replaced by lactose. The groups took the medications once per day for 6 wk. Outcome Measures • Symptoms were assessed using the Western Ontario and McMaster Individual Osteoarthritis Index (WOMAC) and a visual analogue scale (VAS). The primary outcome was the reduction in the total WOMAC score. The subscale scores on the WOMAC for pain, stiffness, and physical function, the VAS scores, and the use of rescue medications were secondary outcomes. Results • Of the 120 enrolled participants, 116 completed the study. The treatments with D-002, D-003, and D-002/D-003 reduced the mean total WOMAC scores significantly from baseline to

    A 30-year-old man with a history of epilepsy and substance misuse presented to the hospital with status epilepticus. Difficult seizure control necessitated anaesthetising the patient followed by intubation and ventilation. A clonidine infusion was started as the patient developed withdrawal syndrome and was difficult to wean off mechanical ventilation. Once the withdrawal syndrome was controlled, the clonidine was abruptly stopped. Two hours after stopping the infusion, the patient developed high-grade fever, severe hypertension, tachycardia, profound sweating and lacrimation. The patient then developed respiratory distress syndrome secondary to acute pulmonary oedema. Clonidine withdrawal as a cause of such response was proposed. Reversal of symptoms and successful reweaning was achieved by restarting a low-dose clonidine infusion followed by slow downward titration and use of oral clonidine as a step-down measure. The patient was subsequently discharged from the intensive care unit.

    Child sexual abuse and adult sexual assault have been linked to increased self-blame, posttraumatic stress symptoms, and alcohol use. The current study aims to examine (a) whether these constructs explain women's risk for later adult sexual assault and revictimization, (b) whether such factors differentially confer risk for specific types of adult sexual assault (i.e., substance-facilitated and forcible), and (c) if self-blame confers risk indirectly through other risk factors. Multiple types of self-blame, posttraumatic stress, and alcohol use were examined among 929 female college students as serial mediators of the relationship between child sexual abuse and adult sexual assault and as risk factors for sexual revictimization among child sexual abuse survivors. In the model predicting risk for substance-facilitated adult sexual assault, child sexual abuse indirectly predicted greater risk for substance-facilitated adult sexual assault mediated through two separate paths: global blame-to-posttraumatic-stress and global blame-to-alcohol use. In the model predicting risk for forcible adult sexual assault, child sexual abuse directly predicted greater risk for forcible adult sexual assault, and this relation was mediated by the global blame-to-posttraumatic-stress path. Among child sexual abuse survivors, child sexual abuse specific characterological and behavioral self-blame directly predicted greater risk for forcible and substance-facilitated revictimization, but the pathways were not mediated by posttraumatic stress or alcohol use. Results emphasize the importance of assessing different types of self-blame in predicting posttraumatic stress symptoms as well as examining risk for sexual victimization and revictimization. Findings did not support hypotheses that increased posttraumatic stress would predict increased alcohol use but did indicate that heightened self-blame is consistently associated with heightened posttraumatic stress and that heightened global self

    Abstract Purpose: Research linking family rejection and health outcomes in sexual minority people is mostly limited to North America. We assessed the associations between negative treatment by family members and depressive symptoms, life satisfaction, suicidality, and tobacco/alcohol use in sexual minority women (SMW) in Viet Nam. Methods: Data were from an anonymous internet survey (n = 1936). Latent class analysis characterized patterns of negative treatment by family members experienced by respondents. Latent class with distal outcome modeling was used to regress depressive symptoms, life satisfaction, suicidality, and tobacco/alcohol use on family treatment class, controlling for predictors of family treatment and for two other types of sexual prejudice. Results: Five latent family treatment classes were extracted, including four negative classes representing varying patterns of negative family treatment. Overall, more than one negative class predicted lower life satisfaction, more depressive symptoms, and higher odds of attempted suicide (relative to the non-negative class), supporting the minority stress hypothesis that negative family treatment is predictive of poorer outcomes. Only the most negative class had elevated alcohol use. The association between family treatment and smoking status was not statistically significant. The most negative class, unexpectedly, did not have the highest odds of having attempted suicide, raising a question about survivor bias. Conclusion: This population requires public health attention, with emphasis placed on interventions targeting the family to promote acceptance and to prevent negative treatment, and interventions supporting those SMW who encounter the worst types of negative family treatment.

    Background Previous studies suggest patients with co-occurring alcohol use disorders (AUDs) and severe mental health symptoms (SMHS) are less satisfied with standard AUD treatment when compared to patients with an AUD alone. This study compared patient satisfaction with standard AUD treatment among patients with and without SMHS and explored how standard treatment might be improved to better address the needs of these patients. Methods Eighty-nine patients receiving treatment for an AUD either at an inpatient hospital, outpatient clinic, inpatient detoxification, or residential/therapeutic community services were surveyed. Patient satisfaction with treatment was assessed using the Treatment Perception Questionnaire (range: 0–40). Patients were stratified according to their score on the Depression Anxiety Stress Scale. Forty patients scored in the extremely severe range of depression (score >14) and/or anxiety (score >10) (indicating SMHS) and 49 patients did not. An inductive content analysis was also conducted on qualitative data relating to areas of service improvement. Results Patients with SMHS were found to be equally satisfied with treatment (mean =25.10, standard deviation =8.12) as patients with an AUD alone (mean =25.43, standard deviation =6.91). Analysis revealed that being an inpatient in hospital was associated with reduced treatment satisfaction. Patients with SMHS were found to be significantly less satisfied with staffs’ understanding of the type of help they wanted in treatment, when compared to patients with AUDs alone. Five areas for service improvement were identified, including staff qualities, informed care, treatment access and continuity, issues relating to inpatient stay, and addressing patients’ mental health needs. Conclusion While findings suggest that AUD treatment services adequately meet the needs of patients with SMHS in treatment, patients with SMHS do feel that staff lack understanding of their treatment needs. Findings have

    Background and Aims Questions over the clinical significance of cannabis withdrawal have hindered its inclusion as a discrete cannabis induced psychiatric condition in the Diagnostic and Statistical Manual of Mental Disorders (DSM IV). This study aims to quantify functional impairment to normal daily activities from cannabis withdrawal, and looks at the factors predicting functional impairment. In addition the study tests the influence of functional impairment from cannabis withdrawal on cannabis use during and after an abstinence attempt. Methods and Results A volunteer sample of 49 non-treatment seeking cannabis users who met DSM-IV criteria for dependence provided daily withdrawal-related functional impairment scores during a one-week baseline phase and two weeks of monitored abstinence from cannabis with a one month follow up. Functional impairment from withdrawal symptoms was strongly associated with symptom severity (p = 0.0001). Participants with more severe cannabis dependence before the abstinence attempt reported greater functional impairment from cannabis withdrawal (p = 0.03). Relapse to cannabis use during the abstinence period was associated with greater functional impairment from a subset of withdrawal symptoms in high dependence users. Higher levels of functional impairment during the abstinence attempt predicted higher levels of cannabis use at one month follow up (p = 0.001). Conclusions Cannabis withdrawal is clinically significant because it is associated with functional impairment to normal daily activities, as well as relapse to cannabis use. Sample size in the relapse group was small and the use of a non-treatment seeking population requires findings to be replicated in clinical samples. Tailoring treatments to target withdrawal symptoms contributing to functional impairment during a quit attempt may improve treatment outcomes. PMID:23049760

  1. The Role of the Gut-Brain Axis in Alcohol Use Disorders

    Gorky, Jonathan; Schwaber, James

    2015-01-01

    Neuroimmune and inflammatory processes have been locally associated with the amygdala in alcohol exposure and withdrawal. We and others have suggested that this inflammation in the amygdala may cause disturbance of neural function observed as anxiety and autonomic distress in withdrawal. Despite the potential importance of the robust neuroinflammatory response, the mechanisms contributing to this response are not well understood. We review literature that suggests the effects of alcohol, and other substances of abuse, cause dysbiosis of the gut microbiome. This peripheral response may modulate neuroprotective vagal afferent signaling that permits and exacerbates a neuroinflammatory response in the amygdala. We will examine the mounting evidence that suggests that (1) gut dysbiosis contributes to neuroinflammation, especially in the context of alcohol exposure and withdrawal, (2) the neuroinflammation in the amygdala involves the microglia and astrocytes and their effect on neural cells, and (3) amygdala neuroinflammation itself contributes directly to withdrawal behavior and symptoms. The contribution of the gut to an anxiogenic response is a promising therapeutic target for patients suffering with withdrawal symptoms given the safe and well-established methods of modulating the gut microbiome.

    This study aims to analyse mental symptoms, psychotropic drug use and alcohol consumption, in immigrant women born in Finland, the other Nordic countries, Eastern Europe, Western Europe and countries outside Europe, compared with Swedish-born women, and furthermore, to study if age at immigration may have an influence. All women (n=10,766) aged 50-59 years and living in the Lund area of southern Sweden received a postal invitation to a health survey named the Women's Health in Lund Area; 64.2% (n=6917) participated. The participants answered a questionnaire including prevalence of mental symptoms during the past 3 months, regular use of psychotropic drugs, alcohol consumption during an average week, country of birth and age at immigration. Severe mental symptoms were more common among most immigrant groups compared with native Swedes, but the association to country of birth was not significant after adjustment for possible confounders. Regular use of hypnotics was more common among Nordic immigrants only (odds ration, OR = 4.4). East European and non-European immigrants less often were alcohol consumers (OR = 1.6 and OR = 3.8). Heavy drinking was more common among non-Nordic immigrants who immigrated at a younger age than at an older age. Furthermore, it was found that although East European and non-European immigrants had a higher educational level, they were less often gainfully employed compared with native Swedes. In middle-aged women, country of birth as well as age at immigration are important factors to consider in relation to alcohol consumption, but these factors may be of less importance considering mental health.

    The aim of the present study was to evaluate relationship of PTSD symptom severity with severity of ADHD symptoms while controlling the effect of childhood trauma in a sample of male inpatients with alcohol use disorder (AUD). Participants included 190 male inpatients with AUD. Participants were evaluated with the Childhood Trauma Questionnaire (CTQ-28), the Adult ADHD Self-Report Scale (ASRS) and PTSD Checklist Civilian version (PCL-C). PTSD and ADHD scores were mildly correlated with severity of childhood trauma and types of traumas, the only exception was emotional neglect, which was not correlated with PTSD and ADHD. Severity of ADHD symptoms was associated with the severity of PTSD symptoms, together with the severity of childhood trauma in a linear regression model. In another linear regression model where dimensions of ADHD and childhood trauma were considered as independent variables, emotional abuse and both inattentive and hyperactive/impulsive dimensions of ADHD were associated with the severity of PTSD. These findings suggest that the severity of adult ADHD symptoms is related with the severity of PTSD symptoms, while severity of childhood trauma, particularly emotional abuse may have an mediating role on this relationship among male inpatients with AUD.

    Nalmefene (Selincro®) is a selective opioid receptor antagonist, licensed in April 2014 in Switzerland for the reduction of alcohol consumption in adults with a high drinking risk level. 200 reports of adverse drug reactions of nalmefene have been documented worldwide in the WHO global pharmacovigilance database between 7th March 1997 to 1st March 2015. In 21 cases (10,5%) nalmefene and an opioid were administered concomitantly, causing withdrawal symptoms. Until now, the regional pharmacovigilance center in Zurich received four cases of nalmefene combined with opioids. This combination should be avoided.

    Alcohol use disorder (AUD) is associated with depression. Although attendance at Alcoholics Anonymous (AA) meetings predicts reductions in drinking, results have been mixed about the salutary effects of AA on reducing depressive symptoms. In this single-group study, early AA affiliates (n = 253) were recruited, consented, and assessed at baseline, 3, 6, 9, 12, 18, and 24 months. Lagged growth models were used to investigate the predictive effect of AA attendance on depression, controlling for concurrent drinking and treatment attendance. Depression was measured using the Beck Depression Inventory (BDI) and was administered at baseline 3, 6, 12, 18, and 24 months. Additional predictors of depression tested included spiritual gains (Religious Background and Behavior questionnaire [RBB]) and completion of 12-step work (Alcoholics Anonymous Inventory [AAI]). Eighty-five percent of the original sample provided follow-up data at 24 months. Overall, depression decreased over the 24 month follow-up period. AA attendance predicted later reductions in depression (slope = -3.40, p = .01) even after controlling for concurrent drinking and formal treatment attendance. Finally, increased spiritual gains (RBB) also predicted later reductions in depression (slope = -0.10, p = .02) after controlling for concurrent drinking, treatment, and AA attendance. In summary, reductions in alcohol consumption partially explained decreases in depression in this sample of early AA affiliates, and other factors such as AA attendance and increased spiritual practices also accounted for reductions in depression beyond that explained by drinking.

    Sexual assault occurring when the victim is unable to consent or resist due to the use or administration of alcohol or drugs (i.e., incapacitated/drug-or-alcohol facilitated rape; IR/DAFR) is a particularly prevalent form of victimization experienced by college women. By definition, substance use precedes IR/DAFR; however, few studies have examined other potential risk factors for IR/DAFR that may be unique from those associated with forcible rape (FR; i.e., sexual assault occurring due to threats or physical restraint). The present investigation tested a model of risk for IR/DAFR and FR suggesting that child or adolescent sexual abuse (CASA) leads to posttraumatic stress disorder (PTSD) symptoms, which in turn increase the likelihood of IR/DAFR, but not FR. Results revealed full mediation for PTSD hyperarousal symptoms in the pathway between CASA and IR/DAFR, and partial mediation for hyperarousal symptoms in the pathway between CASA and FR. Theoretical and clinical implications are discussed. PMID:22929343

    PubMed

    Calixto, E

    2016-01-28

    The sudden interruption of the increase of the concentration of the gamma-aminobutyric acid (GABA), determines an increase in neuronal activity. GABA withdrawal (GW) is a heuristic analogy, with withdrawal symptoms developed by other GABA receptor-agonists such as alcohol, benzodiazepines, and neurosteroids. GW comprises a model of neuronal excitability validated by electroencephalogram (EEG) in which high-frequency and high-amplitude spike-wave complexes appear. In brain slices, GW was identified by increased firing synchronization of pyramidal neurons and by changes in the active properties of the neuronal membrane. GW induces pre- and postsynaptic changes: a decrease in GABA synthesis/release, and the decrease in the expression and composition of GABAA receptors associated with increased calcium entry into the cell. GW is an excellent bioassay for studying partial epilepsy, epilepsy refractory to drug treatment, and a model to reverse or prevent the generation of abstinences from different drugs.

  14. Epigenetic basis of the dark side of alcohol addiction.

    2017-02-04

    Alcoholism is a complex brain disease characterized by three distinct stages of the addiction cycle that manifest as neuroadaptive changes in the brain. One such stage of the addiction cycle is alcohol withdrawal and the negative affective states that promote drinking and maintain addiction. Repeated alcohol use, genetic predisposition to alcoholism and anxiety, and alcohol exposure during crucial developmental periods all contribute to the development of alcohol-induced withdrawal and negative affective symptoms. Epigenetic modifications within the amygdala have provided a molecular basis of these negative affective symptoms, also known as the dark side of addiction. Here, we propose that allostatic change within the epigenome in the amygdala is a prime mechanism of the biological basis of negative affective states resulting from, and contributing to, alcoholism. Acute alcohol exposure produces an anxiolytic response which is associated with the opening of chromatin due to increased histone acetylation, increased CREB binding protein (CBP) levels, and histone deacetylase (HDAC) inhibition. After chronic ethanol exposure, these changes return to baseline along with anxiety-like behaviors. However, during withdrawal, histone acetylation decreases due to increased HDAC activity and decreased CBP levels in the amygdala circuitry leading to the development of anxiety-like behaviors. Additionally, innately higher expression of the HDAC2 isoform leads to a deficit in global and gene-specific histone acetylation in the amygdala that is associated with a decrease in the expression of several synaptic plasticity-associated genes and maintaining heightened anxiety-like behavior and excessive alcohol intake. Adolescent alcohol exposure also leads to higher expression of HDAC2 and a deficit in histone acetylation leading to decreased expression of synaptic plasticity-associated genes and high anxiety and drinking behavior in adulthood. All these studies indicate that the

    We examined the associations between depressive symptoms and four indicators of alcohol consumption (high frequency of drinking, frequency of heavy episodic drinking, problem drinking, and possible alcohol dependence). We also explored whether personal importance of religious faith as well as healthy lifestyle had any modifying roles in these relationships. During 2007-2008, 3,220 students at seven UK universities completed a questionnaire containing questions on CAGE, frequency alcohol use, heavy episodic drinking, modified Beck-Depression Inventory, physical activity and sleep, and importance of religious faith. Multivariate logistic regressions were performed separately for four alcohol consumption indicators, stratified by gender. Controlling for demographic variables, depressive symptoms were positively associated with problem drinking and possible alcohol dependence for both genders. Religiosity was negatively associated with frequency of drinking and heavy episodic drinking among both genders, while healthy lifestyle was not associated with any of the four measures of alcohol consumption among both genders. No evidence suggested that either religiosity or healthy lifestyle modified the relationships between depressive symptoms and any of the four measures of alcohol consumption. This study shows a link between hazardous drinking and mental ill health and suggests religiosity as a protective factor for high alcohol consumption. Promotion of students' mental and spiritual health could have a preventive role in hazardous drinking at universities.

    Background: Currently, benzodiazepines are the preferred drugs in the management of alcohol withdrawal symptoms. Chlordiazepoxide and diazepam, the most frequently used drugs have a long duration of action and are converted to active metabolites in the liver, while lorazepam is shorter acting, with no active metabolites. Objective: To compare and evaluate the safety and efficacy of lorazepam and chlordiazepoxide in patients with alcohol dependence syndrome with symptoms of alcohol withdrawal. Materials and Methods: This was a prospective, randomized, double-blind, study carried out at a teaching hospital in Bangalore. Sixty patients aged ≥18 y with alcohol dependence syndrome with mild-to-moderate withdrawal symptoms were allocated at a ratio of 1:1 to either lorazepam or chlordiazepoxide, by means of a computer-generated randomization chart. Thirty patients each were started with lorazepam tablets 8 mg/day and chlordiazepoxide 80 mg/day. For both treatment groups, the dose was tapered and at the end of 8 days, the patients were drug-free. The severity of alcohol dependence was assessed using the Severity of Alcohol Dependence Questionnaire (SADQ). The CIWA-Ar was used for quantification of withdrawal symptoms. Liver function tests were performed at baseline and at the end of the study. Results: Of the 60 patients included in the study, 15 patients each had mild and moderate withdrawal symptoms in the chlordiazepoxide group and 17 and 13 patients respectively in the lorazepam group, based on the SADQ score. At baseline, the mean CIWA-Ar scores were similar in both the treatment groups: 24.77±5.98 in the chlordiazepoxide group and 24.90±6.12 in the lorazepam group. There was a significant intragroup decrease in the CIWA-Ar scores measured from baseline to the end of 8 days (p<0.0001) and 12 days (p<0.0001) in both treatment groups; however, there was no significant difference between the two groups. There was no significant difference observed in the liver

    Aggression and suicidality are two serious public health concerns among U.S. veterans that can co-occur and share many overlapping risk factors. The current study aims to elucidate the contribution of posttraumatic stress disorder (PTSD) symptom clusters defined by a five-factor model and alcohol misuse in predicting aggression and suicide attempts among veterans entering residential treatment for PTSD. Participants were 2570 U.S. veterans across 35 Veterans Health Administration sites. Multinomial logistic regression models were used to identify correlates of aggression only (n = 1471; 57.2%), suicide attempts only (n = 41; 1.6%), co-occurring aggression and suicide attempts (n = 202; 7.9%), and neither behavior (n = 856; 33.3%) over the past four months. When compared to veterans endorsing neither behavior, greater PTSD re-experiencing symptoms were related to suicide attempts (odds ratio [OR] = 1.58, 95% confidence interval [CI] = 1.09-2.30), aggression (OR = 1.13, 95% CI = 1.02-1.26), and co-occurring aggression and suicide (OR = 1.38, 95% CI = 1.13-1.68), and higher PTSD dysphoric arousal symptoms and alcohol misuse symptoms were related to aggression (OR = 1.54, 95% CI = 1.38-1.71; OR = 1.30, 95% CI = 1.18-1.44, respectively) and co-occurring aggression and suicide (OR = 1.66, 95% CI = 1.35-2.04; OR = 1.50, 95% CI = 1.28-1.75, respectively). Our findings suggest that assessment of PTSD symptom clusters and alcohol misuse can potentially help to identify veterans who endorse suicide attempts, aggression, or both concurrently. These results have important implications for risk assessment and treatment planning with U.S. veterans seeking care for PTSD.

    Introduction: Melissa officinalis is a medical and aromatic plant that is used for its hypnotic, sedative, and spasmolytic effects. This report presents a case study of30-year-old patient who was admitted to an emergency department with restlessness, tremor, distractibility, and sweating following a discontinuation of Melissa officinalis consumption. Case report: In this case, withdrawal symptoms may be related to the dependence effect caused by long-term use of Melissa officinalis. Although Melissa officinalis, a plant, is preferred by many patients as an alternative to pharmaceutical drugs, patients should be made aware that it may have a risk of dependency and can lead to withdrawal symptoms.

    The objective of this multicentre, randomised, double-blind study was to compare a combined oral contraceptive (COC) containing oestradiol valerate/dienogest (E2V/DNG) administered in a dynamic dosing regimen with a monophasic COC containing ethinyloestradiol/levonorgestrel (EE/LNG), with regard to their ability to reduce the frequency and intensity of headache and pelvic pain in women with hormone withdrawal-associated symptoms (HWAS). Women aged 18-50 years received E2V/DNG in an oestrogen step-down and progestin step-up regimen (26/2 regimen; n = 223) or EE 20 μg/LNG 100 μg (21/7 regimen; n = 218) over six cycles. Headache and pelvic pain were assessed using a visual analogue scale (VAS) during cycle days 22-28. Rescue medication use was also assessed. E2V/DNG was superior to EE/LNG with regard to reducing the frequency and intensity of headache and pelvic pain from baseline to cycle 6 (change from baseline in the average of the three highest VAS values [mean ± standard deviation]: 47.7 ± 29.4 vs 34.5 ± 25.7 mm, respectively; p < 0.0001). The use of rescue medication was also significantly reduced with E2V/DNG compared with EE/LNG (p < 0.05). E2V/DNG may be a good option for women who experience HWAS with traditional 21/7-day regimen COCs.

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

    Young adults with psychiatric illnesses are more likely to use cannabis and experience problems from use. It is not known whether those with a lifetime psychiatric illness experience a prolonged cannabis withdrawal syndrome with abstinence. Participants were fifty young adults, aged 18-25, recruited from the Boston-area in 2015-2016, who used cannabis at least weekly, completed the Structured Clinical Interview for DSM-IV to identify Axis I psychiatric diagnoses (PD+ vs PD-), and attained cannabis abstinence with a four-week contingency management protocol. Withdrawal symptom severity was assessed at baseline and at four weekly abstinent visits using the Cannabis Withdrawal Scale. Cannabis dependence, age of initiation, and rate of abstinence were similar in PD+ and PD- groups. There was a diagnostic group by abstinent week interaction, suggesting a difference in time course for resolution of withdrawal symptoms by group, F(4,46)=3.8, p=0.009, controlling for sex, baseline depressive and anxiety symptoms, and frequency of cannabis use in the prior 90days. In post hoc analyses, there was a difference in time-course of cannabis withdrawal. PD- had significantly reduced withdrawal symptom severity in abstinent week one [t(46)=-2.2, p=0.03], while PD+ did not report improved withdrawal symptoms until the second abstinent week [t(46)=-4.1, p=0.0002]. Cannabis withdrawal symptoms improved over four weeks in young people with and without a lifetime psychiatric diagnosis. However, those with a psychiatric illness reported one week delayed improvement in withdrawal symptom severity. Longer duration of cannabis withdrawal may be a risk factor for cannabis dependence and difficulty quitting.

    Alcoholism, a worldwide disorder, is the cause of a variety of neurologic disorders. In this article we discuss the cellular pathophysiology of ethanol addition and abuse as well as evidence supporting and refuting the role of inheritance in alcoholism. A genetic marker for alcoholism has not been identified, but neurophysiologic studies may be promising. Some neurologic disorders related to longterm alcoholism are due predominantly to inadequate nutrition (the thiamine deficiency that causes Wernicke's encephalopathy), but others appear to involve the neurotoxicity of ethanol on brain (alcohol withdrawal syndrome and dementia) and peripheral nerves (alcoholic neuropathy and myopathy).

    Objective To assess whether the combined oral contraceptive (COC) ethinylestradiol (EE) 20 μg/drospirenone 3 mg taken in a 24/4-day regimen (ie, 4-day hormone-free interval) is more effective than an EE 20 μg/desogestrel (DSG) 150 μg COC taken in a 21/7-day regimen (ie, 7-day hormone-free interval) in reducing hormone withdrawal-associated symptoms (HWAS). Methods This double-blind, randomized study (NLM identifier: NCT01076582) was conducted at 34 centers in 12 countries. Otherwise healthy women who experienced ≥2 HWAS of headache, pelvic pain, and/or bloating when using their current COCs in a 21/7-day regimen were recruited. Subjects rated the severity of their HWAS daily on a seven-point Likert scale during a baseline cycle and during four 28-day cycles with EE/drospirenone 24/4 (n=290) or EE/DSG 21/7 (n=304). The primary variable was the mean change from baseline to cycle 4 in the composite HWAS score (sum of scores for all three symptoms) during cycle days 22–28. Results In the EE/drospirenone 24/4 group, the mean (standard deviation) composite HWAS score during cycle days 22–28 was reduced from 42.2 (24.8) at baseline to 12.8 (13.4) at cycle 4 (change from baseline: −30.3 [22.9]). In the EE/DSG 21/7 group, the corresponding value was reduced from 41.9 (25.8) to 14.3 (13.2) (change from baseline: −27.7 [24.8]), not significantly different versus EE/drospirenone 24/4. Bleeding pattern, treatment response, rescue medication use, compliance, quality of life, and tolerability were similar between treatments. Conclusion Both EE/drospirenone 24/4 and EE/DSG 21/7 reduced the composite HWAS score from baseline to cycle 4 in otherwise healthy women. The differences between treatments were too small to be statistically significant. PMID:26056491

    2016-01-01

    The large class of CNS-depressant medications-the benzodiazepines-have been extensively used for over 50 years, anxiety disorders being one of the main indications. A substantial proportion (perhaps up to 20-30 %) of long-term users becomes physically dependent on them. Problems with their use became manifest, and dependence, withdrawal difficulties and abuse were documented by the 1980s. Many such users experience physical and psychological withdrawal symptoms on attempted cessation and may develop clinically troublesome syndromes even during slow tapering. Few studies have been conducted to establish the optimal withdrawal schedules. The usual management comprises slow withdrawal over weeks or months together with psychotherapy of various modalities. Pharmacological aids include antidepressants such as the SSRIs especially if depressive symptoms supervene. Other pharmacological agents such as the benzodiazepine antagonist, flumazenil, and the hormonal agent, melatonin, remain largely experimental. The purpose of this review is to analyse the evidence for the efficacy of the usual withdrawal regimes and the newer agents. It is concluded that little evidence exists outside the usual principles of drug withdrawal but there are some promising leads.

    Animal research suggests that anhedonia is a tobacco withdrawal symptom, but this topic has not been addressed definitively in research with humans. This research sought to determine whether anhedonia is (a) an element of the tobacco withdrawal syndrome in humans and (b) an impediment to successful tobacco cessation. Data were from 1,175 smokers (58.3% women; 85.5% White) participating in a randomized double-blind, placebo-controlled trial of smoking cessation pharmacotherapies. Ecological momentary assessments for 5 days before and 10 days after the target quit day were used to assess anhedonia and other established withdrawal symptoms. Consistent with drug withdrawal, anhedonia showed an inverted-U pattern of change in response to tobacco cessation and was associated with the severity of other withdrawal symptoms and tobacco dependence. Postquit anhedonia was associated with decreased latency to relapse (hazard ratio = 1.09, 95% confidence interval [CI] [1.02, 1.17]) and with lower 8-week point-prevalence abstinence (odds ratio = .91, 95% CI [.86, .97])-relations that remained significant when other withdrawal symptoms were included as predictors. Finally, nicotine replacement therapy nearly fully suppressed the increase in abstinence-related anhedonia (β = -.66, p < .001), suggesting agonist suppression of withdrawal. Results suggest that anhedonia is a unique and motivationally significant element of the tobacco withdrawal syndrome in humans. These results have implications for defining and assessing tobacco use disorder and for understanding and treating tobacco addiction.

    Cessation from chronic alcohol abuse often produces a dysphoric state that can persist into protracted withdrawal. This dysphoric state is theorized to function as a negative reinforcer that maintains excessive alcohol consumption and/or precipitates relapse in those struggling to abstain from alcohol. However, we know relatively little regarding the impact of cessation from binge drinking on behavioral measures of negative affect and related neurobiology. Male C57BL/6J mice were given access to unsweetened 20% alcohol for 6 weeks under modified Drinking-in-the-dark procedures, followed by behavioral testing beginning either 1 or 21 days into withdrawal. Mice were administered a behavioral test battery consisting of: the elevated plus maze, light/dark box, novel object test, marble burying test, Porsolt forced swim test and sucrose preference test to assess anxiogenic and depressive signs. Egr1 immunostaining was used to quantify cellular activity within the central nucleus of the amygdala (CEA), basolateral amygdala (BLA), bed nucleus of the stria terminalis (BNST), and the nucleus accumbens (Acb) shell (AcbSh) and core (AcbC). Compared to water controls, alcohol-drinking mice exhibited higher indices of emotionality in the majority of behavioral assays. The hyper-emotionality exhibited by binge drinking mice was apparent at both withdrawal time-points and correlated with higher Egr1+ cell counts in the CEA and BNST, compared to controls. These data show that affective symptoms emerge very early after cessation of binge drinking and persist into protracted withdrawal. A history of binge drinking is capable of producing enduring neuroadaptations within brain circuits mediating emotional arousal.

    Naloxone-induced withdrawal was studied in seven patients currently dependent only on injecting buprenorphine, within 3 to 6 hours of their last dose. Withdrawal severity began to rise from 5 minutes and reached a peak at 60 minutes after 1.2 mg naloxone given intravenously. The mean withdrawal severity score was significantly higher at 30, 60 and 90 minutes compared to the baseline. The most frequent withdrawal signs and symptoms were mydriasis, systolic hypertension, tachypnoea, muscle pains, yawning, anxiety, restlessness and craving.

    Given that prior research implicates smoking abstinence in increased premenstrual symptoms, tobacco withdrawal, and smoking behaviors, it is possible that women with more severe premenstrual symptoms have stronger expectancies about the effects of smoking and abstaining from smoking on mood and withdrawal. However, such relations have not been previously explored. This study examined relations between premenstrual symptoms experienced in the last month and expectancies that abstaining from smoking results in withdrawal (i.e., smoking abstinence withdrawal expectancies), that smoking is pleasurable (i.e., positive reinforcement smoking expectancies), and smoking relieves negative mood (i.e., negative reinforcement smoking expectancies). In a cross-sectional design, 97 non-treatment seeking women daily smokers completed self-report measures of smoking reinforcement expectancies, smoking abstinence withdrawal expectancies, premenstrual symptoms, mood symptoms, and nicotine dependence. Affect premenstrual symptoms were associated with increased negative reinforcement smoking expectancies, but not over and above covariates. Affect and pain premenstrual symptoms were associated with increased positive reinforcement smoking expectancies, but only affect premenstrual symptoms remained significant in adjusted models. Affect, pain, and water retention premenstrual symptoms were associated with increased smoking abstinence withdrawal expectancies, but only affect premenstrual symptoms remained significant in adjusted models. Findings from this study suggest that addressing concerns about withdrawal and alternatives to smoking may be particularly important in women who experience more severe premenstrual symptoms, especially affect-related changes.

    Inadequate effort during neuropsychological examination results in inaccurate representations of an individual's true abilities and difficulties. As such, performance validity tests (PVTs) are strongly recommended as standard practice during adult-based evaluations. One concern with using PVTs with children is that failure reflects immature cognitive ability rather than non-credible effort. The current study examined performance on the Medical Symptom Validity Test (MSVT) in two large pediatric clinical samples with strikingly different neuropsychological profiles: (1) mild traumatic brain injury (mTBI; n = 510) and (2) fetal alcohol spectrum disorder (FASD; n = 120). Despite higher IQ scores and reading ability, the mTBI group performed significantly worse than the FASD group on all effort indices. Sixteen percent of the mTBI group failed the MSVT, whereas only 5% of the FASD group did. Our findings support the idea that the MSVT measures effort, not ability, in most cases and help to justify incorporating PVTs into pediatric neuropsychological batteries.

    This longitudinal study extended previous work of Wiesner and Capaldi (2003) by examining the validity of differing offending pathways and the prediction from the pathways to substance use and depressive symptoms for 204 young men. Findings from this study indicated good external validity of the offending trajectories. Further, substance use and depressive symptoms in young adulthood (i.e., ages 23-24 through 25-26 years) varied depending on different trajectories of offending from early adolescence to young adulthood (i.e., ages 12-13 through 23-24 years), even after controlling for antisocial propensity, parental criminality, demographic factors, and prior levels of each outcome. Specifically, chronic high-level offenders had higher levels of depressive symptoms and engaged more often in drug use compared with very rare, decreasing low-level, and decreasing high-level offenders. Chronic low-level offenders, in contrast, displayed fewer systematic differences compared with the two decreasing offender groups and the chronic high-level offenders. The findings supported the contention that varying courses of offending may have plausible causal effects on young adult outcomes beyond the effects of an underlying propensity for crime.

    Suicidal ideation and aggression are common correlates of posttraumatic stress disorder (PTSD) among U.S. Iraq and Afghanistan war veterans. The existing literature has established a strong link between these factors, but a more nuanced understanding of how PTSD influences them is needed. The current study examined the direct and indirect relationships between PTSD symptom clusters and suicidal ideation in general aggression (without a specified target) regarding depression, alcohol misuse, and trait anger. Participants were 359 (92% male) U.S. Iraq/Afghanistan war veterans. Path analysis results suggested that the PTSD numbing cluster was directly (β = .28, p < .01) and indirectly (β = .17, p = .001) related through depression. The PTSD hyperarousal cluster was indirectly related to suicidal ideation through depression (β = .13, p < .001). The PTSD reexperiencing cluster was directly related to aggression (β = .17, p < .05), whereas the PTSD numbing and hyperarousal clusters were indirectly related to aggression through trait anger (β = .05, p < .05; β = .20, p < .001). These findings indicate that adjunct treatments aimed at stabilizing anger, depression, and alcohol misuse may help clinicians ameliorate the maladaptive patterns often observed in veterans. These results also point to specific manifestations of PTSD and co-occurring conditions that may inform clinicians in their attempts to identify at risk veterans and facilitate preventative interventions.

    Cannabinoid CB1 receptor antagonists have potential therapeutic benefits, but antagonist-elicited cannabis withdrawal has not been reported in humans. Ten male daily cannabis smokers received 8 days of increasingly frequent 20-mg oral Δ9-tetrahydrocannabinol (THC) dosages (40–120 mg/d) around-the-clock to standardize cannabis dependence while residing on a closed research unit. On the ninth day, double-blind placebo or 20- (suggested therapeutic dose) or 40-mg oral rimonabant, a CB1-cannabinoid receptor antagonist, was administered. Cannabis withdrawal signs and symptoms were assessed before and for 23.5 hours after rimonabant. Rimonabant, THC, and 11-hydroxy-THC plasma concentrations were quantified by mass spectrometry. The first 6 subjects received 20-mg rimonabant (1 placebo); the remaining 4 subjects received 40-mg rimonabant (1 placebo). Fourteen subjects enrolled; 10 completed before premature termination because of withdrawal of rimonabant from clinical development. Three of 5 subjects in the 20-mg group, 1 of 3 in the 40-mg group, and none of 2 in the placebo group met the prespecified withdrawal criterion of 150% increase or higher in at least 3 visual analog scales for cannabis withdrawal symptoms within 3 hours of rimonabant dosing. There were no significant associations between visual analog scale, heart rate, or blood pressure changes and peak rimonabant plasma concentration, area-under-the-rimonabant-concentration-by-time curve (0–8 hours), or peak rimonabant/THC or rimonabant/(THC + 11-hydroxy-THC) plasma concentration ratios. In summary, prespecified criteria for antagonist-elicited cannabis withdrawal were not observed at the 20- or 40-mg rimonabant doses. These data do not preclude antagonist-elicited withdrawal at higher rimonabant doses. PMID:21869692

    1982-01-01

    The diazepam withdrawal syndrome was studied in 10 patients who had abused the drug for 3 to 14 years. In the previous 6 months their consumption of diazepam had ranged from 60 to 120 mg daily; none had used other drugs during this period. The withdrawal period lasted about 6 weeks. The intensity of the symptoms and signs was high initially, fell during the first 2 weeks, then rose again in the third week, before finally declining. Three groups of symptoms and signs were identified. Group A symptoms occurred throughout withdrawal and included tremor, anorexia, insomnia and myoclonus. Group B symptoms and signs were largely confined to the first 10 days and were those of a toxic psychosis. Group C symptoms reached a peak in the third and fourth weeks of withdrawal and were characterized by sense perceptions that were either heightened or lowered. The symptom groups, the presence of tremor and myoclonus, and the relief of symptoms by a test dose permit diazepam withdrawal to be distinguished from anxiety. The biphasic course of the symptoms is probably related to the pharmacokinetics of diazepam. PMID:7139456

    Substantial evidence suggests that both partial dopamine agents and mixed 5-HT1A/2A receptor drugs independently show significant efficacy in reducing alcohol use in both animals and humans. Aripiprazole, which acts as a dopamine/5-HT system stabilizer, approaches the optimal characteristics sought in medication to be considered for testing in the treatment of alcohol dependence. In this randomised, double-blind, confrontation trial with naltrexone, we aimed to investigate the efficacy of aripiprazole on alcohol-drinking indices. Craving and psychiatric symptom improvements were the secondary end points. Seventy-five alcohol dependent subjects were detoxified and were subsequently randomised into two groups, receiving 50 mg of naltrexone and 5-15 mg of aripiprazole, respectively. Craving (Visual Analogue Scale; Obsessive and Compulsive Drinking Scale) and withdrawal (Clinical Institute Withdrawal Assessment) rating scales were applied; psychiatric symptoms were evaluated through the Symptom Check List 90-Revised. The number of subjects remained alcohol free for the entire study period (16 weeks) and the number of subjects relapsed were not significantly different in the two groups. The survival function showed that patients treated with aripiprazole remained abstinent from any alcohol amount for a longer time with respect to those treated with naltrexone. As for craving scores, patients treated with naltrexone showed a better outcome. Results from this study globally place aripiprazole at the same range of efficacy of naltrexone, one of the approved drugs used in alcohol relapse prevention. If it could be demonstrated in placebo-controlled trials that aripiprazole is efficacious in decreasing alcohol use, lessening craving, and attenuating psychopathological symptom severity, we will have gained a powerful agent for the treatment of alcohol-dependent subjects.

  2. The negative effects of alcohol hangover on high-anxiety phenotype rats are influenced by the glutamate receptors of the dorsal midbrain.

    Alcoholism is a chronic disorder characterized by the appearance of a withdrawal syndrome following the abrupt cessation of alcohol intake that includes symptoms of physical and emotional disturbances, anxiety being the most prevalent symptom. In humans, it was shown that anxiety may increase the probability of relapse. In laboratory animals, however, the use of anxiety to predict alcohol preference has remained difficult. Excitatory amino acids as glutamate have been implicated in alcohol hangover and may be responsible for the seizures and anxiety observed during withdrawal. The dorsal periaqueductal gray (DPAG) is a midbrain region critical for the modulation/expression of anxiety- and fear-related behaviors and the propagation of seizures induced by alcohol withdrawal, the glutamate neurotransmission being one of the most affected. The present study was designed to evaluate whether low- (LA) and high-anxiety rats (HA), tested during the alcohol hangover phase, in which anxiety is the most prevalent symptom, are more sensitive to the reinforcing effects of alcohol when tested in a voluntary alcohol drinking procedure. Additionally, we were interested in investigating the main effects of reducing the excitatory tonus of the dorsal midbrain, after the blockade of the ionotropic glutamate receptors into the DPAG, on the voluntary alcohol intake of HA and LA motivated rats that were made previously experienced with the free operant response of alcohol drinking. For this purpose, we used local infusions of the N-metil D-Aspartato (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-kainate receptors antagonist DL-2-Amino-7-phosphonoheptanoic acid - DL-AP7 (10 nmol/0.2 μl) and l-glutamic acid diethyl ester - GDEE (160 nmol/0.2 μl), respectively. Alcohol intoxication was produced by 10 daily bolus intraperitonial (IP) injections of alcohol (2.0 g/kg). Peak-blood alcohol levels were determined by gas-chromatography analysis in order to assess blood-alcohol

    The aim of the present study was to evaluate relationship of self-mutilative behaviour (SMB) with the severity of childhood trauma and adult attention-deficit/hyperactivity disorder (ADHD) symptoms in a sample of inpatients with alcohol use disorder (AUD). Participants included 188 inpatients with AUD. Participants were evaluated with the Self-mutilative Behaviour Questionnaire, the Childhood Trauma Questionnaire (CTQ-28) and the Adult ADD/ADHD DSM-IV Based Diagnostic Screening and Rating Scale (Adult ADHD Scale). Among inpatients with AUD those who have a history of SMB constituted the SMB group (n = 57, 30.3%), and those without a history of SMB constituted the group without SMB (n = 131, 69.7%). Risk of high ADHD risk was 2.5 times higher among those with SMB. Adult ADHD Scale and CTQ-28 scores were also higher in the group with SMB. In the first backward logistic regression model, the severity of ADHD symptoms predicted the presence of SMB, together with the severity of childhood trauma, whereas in the second model, physical neglect and inattentive (IN) dimension of ADHD predicted the presence of SMB. These findings suggest that the higher severity of physical neglect and adult IN dimension of ADHD may be related to SMB among inpatients with AUD.

  5. Effectiveness of alcohol-based hand disinfectants in a public administration: Impact on health and work performance related to acute respiratory symptoms and diarrhoea

    PubMed Central

    2010-01-01

    Background The economical impact of absenteeism and reduced productivity due to acute infectious respiratory and gastrointestinal disease is normally not in the focus of surveillance systems and may therefore be underestimated. However, large community studies in Europe and USA have shown that communicable diseases have a great impact on morbidity and lead to millions of lost days at work, school and university each year. Hand disinfection is acknowledged as key element for infection control, but its effect in open, work place settings is unclear. Methods Our study involved a prospective, controlled, intervention-control group design to assess the epidemiological and economical impact of alcohol-based hand disinfectants use at work place. Volunteers in public administrations in the municipality of the city of Greifswald were randomized in two groups. Participants in the intervention group were provided with alcoholic hand disinfection, the control group was unchanged. Respiratory and gastrointestinal symptoms and days of work were recorded based on a monthly questionnaire over one year. On the whole, 1230 person months were evaluated. Results Hand disinfection reduced the number of episodes of illness for the majority of the registered symptoms. This effect became statistically significant for common cold (OR = 0.35 [0.17 - 0.71], p = 0.003), fever (OR = 0.38 [0.14-0.99], p = 0.035) and coughing (OR = 0.45 [0.22 - 0.91], p = 0.02). Participants in the intervention group reported less days ill for most symptoms assessed, e.g. colds (2.07 vs. 2.78%, p = 0.008), fever (0.25 vs. 0.31%, p = 0.037) and cough (1.85 vs. 2.00%, p = 0.024). For diarrhoea, the odds ratio for being absent became statistically significant too (0.11 (CI 0.01 - 0.93). Conclusion Hand disinfection can easily be introduced and maintained outside clinical settings as part of the daily hand hygiene. Therefore it appears as an interesting, cost-efficient method within the scope of company health

    Chronic alcohol consumption can induce alterations in the function and morphology of most if not all brain systems and structures. However, the exact mechanism of brain damage in alcoholics remains unknown. Partial recovery of brain function with abstinence suggests that a proportion of the deficits must be functional in origin (i.e. plastic changes of nerve cells) while neuronal loss from selected brain regions indicates permanent and irreversible damage. There is growing evidence that chronic alcoholism is associated with a derangement in the sulfur amino acid metabolism. Recently, it has been shown that excitatory amino acid (EAA) neurotransmitters and homocysteine levels are elevated in patients who underwent withdrawal from alcohol. Furthermore, it has been found that homocysteine induces neuronal cell damage by stimulating NMDA receptors as well as by producing free radicals. Homocysteine neurotoxicity via overstimulation of N-methyl-D-aspartate receptors may contribute to the pathogenesis of both brain shrinkage and withdrawal seizures linked to alcoholism.

    PubMed

    Santos, Cynthia; Olmedo, Ruben E

    2017-03-01

    Sedative-hypnotic drugs include gamma-Aminobutyric acid (GABA)ergic agents such as benzodiazepines, barbiturates, gamma-Hydroxybutyric acid [GHB], gamma-Butyrolactone [GBL], baclofen, and ethanol. Chronic use of these substances can cause tolerance, and abrupt cessation or a reduction in the quantity of the drug can precipitate a life-threatening withdrawal syndrome. Benzodiazepines, phenobarbital, propofol, and other GABA agonists or analogues can effectively control symptoms of withdrawal from GABAergic agents. Managing withdrawal symptoms requires a patient-specific approach that takes into account the physiologic pathways of the particular drugs used as well as the patient's age and comorbidities. Adjunctive therapies include alpha agonists, beta blockers, anticonvulsants, and antipsychotics. Newer pharmacological therapies offer promise in managing withdrawal symptoms.

    Maternal use of certain drugs during pregnancy can result in transient neonatal signs consistent with withdrawal or acute toxicity or cause sustained signs consistent with a lasting drug effect. In addition, hospitalized infants who are treated with opioids or benzodiazepines to provide analgesia or sedation may be at risk for manifesting signs of withdrawal. This statement updates information about the clinical presentation of infants exposed to intrauterine drugs and the therapeutic options for treatment of withdrawal and is expanded to include evidence-based approaches to the management of the hospitalized infant who requires weaning from analgesics or sedatives.

    1981-01-01

    Long-term, normal-dose benzodiazepine treatment was discontinued in 16 patients who were suspected of being dependent on their medication. The withdrawal was gradual, placebo-controlled, and double-blind. All the patients experienced some form of withdrawal reaction, which ranged from anxiety and dysphoria to moderate affective and perceptual changes. Symptom ratings rose as the drugs were discontinued, but usually subsided to prewithdrawal levels over the next two to four weeks. Other features of the withdrawal included disturbance of sleep and appetite and noticeable weight loss. Electroencephalography showed appreciable reduction in fast-wave activity as the drugs were withdrawn, and an improvement in psychological performance was recorded by the Digit Symbol Substitution Test. Because of the risk of dependence on benzodiazepines these agents should probably not be given as regular daily treatment for chronic anxiety. PMID:6114776

    Ample data suggest alcohol dependence represents a heritable condition, and several research groups have performed linkage analysis to identify genomic regions influencing this disorder. In the present study, a genome-wide linkage scan for alcohol dependence was conducted in a community sample of 565 probands and 1080 first-degree relatives recruited through the UCSF Family Alcoholism Study. The Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA) was used to derive DSM-IV alcohol dependence diagnoses. Although no loci achieved genome-wide significance (i.e., LOD score > 3.0), several linkage peaks of interest (i.e., LOD score > 1.0) were identified. When the strict DSM-IV alcohol dependence diagnosis requiring the temporal clustering of symptoms served as the phenotype, linkage peaks were identified on chromosomes 1p36.31–p36.22, 2q37.3, 8q24.3, and 18p11.21–p11.2. When the temporal clustering of symptoms was not required, linkage peaks were again identified on chromosomes 1p36.31–p36.22 and 8q24.3 as well as novel loci on chromosomes 1p22.3, 2p24.3–p24.1, 9p24.1–p23, and 22q12.3–q13.1. Follow-up analyses were conducted by performing linkage analysis for the 12 alcohol dependence symptoms assessed by the SSAGA across the support intervals for the observed linkage peaks. These analyses demonstrated that different collections of symptoms often assessing distinct aspects of alcohol dependence (e.g., uncontrollable drinking and withdrawal vs. tolerance and drinking despite health problems) contributed to each linkage peak and often yielded LOD scores exceeding that reported for the alcohol dependence diagnosis. Such findings provide insight into how specific genomic regions may influence distinct aspects of alcohol dependence. PMID:20817416

    2010-01-01

    Psychostimulant drugs have powerful reinforcing and hedonic properties and are frequently abused. Cessation of psychostimulant administration results in a withdrawal syndrome characterized by anhedonia (i.e., an inability to experience pleasure). In humans, psychostimulant withdrawal-induced anhedonia can be debilitating and has been hypothesized to play an important role in relapse to drug use. Hence, understanding the neural substrates involved in psychostimulant withdrawal-induced anhedonia is essential. In this review, we first summarize the theoretical perspectives of psychostimulant withdrawal-induced anhedonia. Experimental procedures and measures used to assess anhedonia in experimental animals are also discussed. The review then focuses on neural substrates hypothesized to play an important role in anhedonia experienced after termination of psychostimulant administration, such as with cocaine, amphetamine-like drugs, and nicotine. Both neural substrates that have been extensively investigated and some that need further evaluation with respect to psychostimulant withdrawal-induced anhedonia are reviewed. In the context of reviewing the various neurosubstrates of psychostimulant withdrawal, we also discuss pharmacological medications that have been used to treat psychostimulant withdrawal in humans. This literature review indicates that great progress has been made in understanding the neural substrates of anhedonia associated with psychostimulant withdrawal. These advances in our understanding of the neurobiology of anhedonia may also shed light on the neurobiology of nondrug-induced anhedonia, such as that seen as a core symptom of depression and a negative symptom of schizophrenia.

    Dysregulated catecholamine signaling has long been implicated in drug abuse. Although much is known about adaptations following chronic drug administration, little work has investigated how a single drug exposure paired with withdrawal influences catecholamine signaling in vivo. We used fast-scan cyclic voltammetry in freely moving rats to measure real-time catecholamine overflow during acute morphine exposure and naloxone-precipitated withdrawal in two regions associated with the addiction cycle: the dopamine-dense nucleus accumbens (NAc) and norepinephrine-rich ventral bed nucleus of the stria terminalis (vBNST). We compared dopamine transients in the NAc with norepinephrine concentration changes in the vBNST, and correlated release with specific withdrawal-related behaviors. Morphine increased dopamine transients in the NAc, but did not elicit norepinephrine responses in the vBNST. Conversely, dopamine output was decreased during withdrawal, while norepinephrine was released in the vBNST during specific withdrawal symptoms. Both norepinephrine and withdrawal symptoms could be elicited in the absence of morphine by administering naloxone with an α2 antagonist. The data support reciprocal roles for dopamine and norepinephrine signaling during drug exposure and withdrawal. The data also support the allostasis model and show that negative-reinforcement may begin working after a single exposure/withdrawal episode.

    Chronic alcohol drinking has been associated with the development of a number of abnormalities, including neuron-behavioral disorders, liver, pancreas, and heart-related diseases and inflammation and immune disorders. Because diverse mechanisms are involved in the development of these disorders, the commonly used receptor- or enzyme-specific drugs do not provide comprehensive protection against the adverse effects of alcoholism. This study describes possible therapeutic potency of puerarin (PU) from kudzu root, polyenylphosphatidylcholine from soy (SPCh), and curcumin (CU) from turmeric against alcohol's addiction-related and inflammatory-related abnormalities in alcohol-preferring P rats receiving free choice water and 15% ethanol in water. P-rats were fed once daily either the vehicle (for control) or different doses of PU, SPCh, CU, PU + SPCh, or PU + CU. The rats were divided in two groups: one received water alone, and the other free choice water and ethanol. Four rats from each group were fitted with electroencephalogram (EEG) electrodes for EEG recording. After 70 days of alcohol drinking, alcohol was withdrawn for 2 weeks, and the withdrawal symptoms were assessed. This study showed that alcohol drinking for 70 days (1) caused liver inflammation characterized by elevated tumor necrosis factor-alpha, interleukin-1beta, and matrix metalloproteinase-9 expression and (2) dysregulated lipopolysaccharide (LPS)-induced pleurisy. Alcohol withdrawal after 70 days of drinking generated severe withdrawal symptoms including seizure-type EEG activity. PU suppressed the addiction-mediated abnormalities but did not affect the inflammation-related abnormalities, while SPCh or CU suppressed only the inflammation-related abnormalities in alcohol-drinking rats subjected to LPS-induced pleurisy. A combination of PU with SPCh or CU suppressed both the addiction-related and inflammation-related abnormalities of alcohol drinking. Therefore, a mixture consisting of PU and either

    Over the past decade, bupropion has become a major pharmacotherapy for smoking cessation in the Western world. Unlike other smoking cessation pharmacotherapies, bupropion is a non-nicotine treatment. Compared with a placebo control, bupropion approximately doubles smoking quit rates. Most smoking cessation pharmacotherapies are thought to work, in part, by reducing nicotine withdrawal and craving. This article reviews preclinical, human laboratory and clinical trial studies of the effect of bupropion on nicotine withdrawal and craving. Preclinical studies demonstrate that in rats undergoing nicotine withdrawal, bupropion can dose-dependently lower changes in brain-reward threshold and somatic signs of nicotine withdrawal. Human laboratory studies have demonstrated that bupropion can alleviate some nicotine withdrawal symptoms, including depressed mood, irritability, difficulty concentrating and increased appetite. Moreover, bupropion has shown some efficacy in alleviating craving to smoke. Clinical trials of bupropion have offered mixed support of its ability to reduce nicotine withdrawal, weight gain during treatment and craving. Strong mediational evidence of bupropion's action through relief of withdrawal and craving in smoking cessation is growing. Greater understanding of the psychological mechanisms of bupropion action will likely be obtained through advances in the conceptualization and measurement of withdrawal and craving. Improvements in the efficacy of bupropion may be achieved through pharmacogenetic studies, with particular emphasis on its metabolites. Ultimately, the efficacy of bupropion may be augmented by combination with other agents that target withdrawal and craving through complementary neurobiological processes.

    Intrathecal baclofen (ITB) infusion has become a common treatment for severe spasticity. Many complications of these drug delivery systems have been reported such as those related to improper dosing, mechanical failure of the implanted pump or catheter, or post-operative wound issues. We report a case of ITB withdrawal after pseudomeningocele aspiration. A 21 year-old male with spastic quadriparesis due to traumatic brian injury (TBI) presented with a pseudomeningocele surrounding an ITB pump (215 mcg/day, continuous) implanted in the abdomen. The pseudomeningocele was percutaneously aspirated and approximately 15 hours later the patient developed signs and symptoms of acute baclofen withdrawal. As a result, the patient underwent an exploration of the ITB infusion system with an intraoperative epidural blood patch. The symptoms of ITB withdrawal improved over the next 18 hours. The subcutaneous cerebrospinal fluid (CSF) collection partially recurred 48 hours later, but this resolved after a second epidural blood patch. The case illustrates a unique presentation of a serious complication of ITB infusion. This underscores that timely diagnosis and treatment of acute baclofen withdrawal is key to optimal outcomes.

  16. Rodent Models of Genetic Contributions to Motivation to Abuse Alcohol

    PubMed Central

    Crabbe, John C.

    2016-01-01

    The distinction between alcohol use (normative) and abuse (unfortunately common) implies dysregulation of motivation directed toward the drug. Genetic contributions to abuse risk are mediated through personality differences, other predispositions to drink excessively, and differences in sensitivity to the acute and chronic consequences of the drug. How to assess motivation in laboratory animals is not straightforward but risk factors for and consequences of alcohol abuse can be modeled with reasonable fidelity in laboratory rodents. Remarkably few rodent studies focus on the genetic contributions to alcohol’s reinforcing value: almost all examine preferential drinking of unflavored alcohol over water. Such studies will likely never avoid the confounding role of taste preferences and most often yield intake levels insufficient to yield a pharmacologically significant blood alcohol level. Genotypes that avoid alcohol probably do so based on pre-ingestive sensory cues; however, post-ingestive consequences are also important. Thus, the quest for improved measures of reinforcing value continues. We have genetic differences aplenty, but still lack evidence that any genotype will readily self-administer alcohol to the devastating extent that many alcoholics will. Encouraging results that are emerging include improved behavioral methods for elevating alcohol intake and inferring alcohol reinforcement, as well as new genetic animal models. Several ingenious assays to index alcohol’s motivational effects have been used extensively. Alcoholic drinking that attempts to prevent or to alleviate withdrawal symptoms has been modeled. Another characteristic of alcoholic drinking is its persistence despite abundant evidence to the drinker of the damaging effects of the excessive drinking on work, relationships, and/or health. Modeling such persistence in rodents has been uncommon to date. New genetic animal models include lines of mice selectively bred for chronic high drinking

    This article reviews the neurocognitive and neuroimaging literature regarding the effect of alcohol use on human adolescent brain structure and function. Adolescents who engage in heavy alcohol use, even at subdiagnostic levels, show differences in brain structure, function, and behavior when compared with non-drinking controls. Preliminary longitudinal studies have helped disentangle premorbid factors from consequences associated with drinking. Neural abnormalities and cognitive disadvantages both appear to predate drinking, particularly in youth who have a family history of alcoholism, and are directly related to the neurotoxic effect of alcohol use. Binge drinking and withdrawal and hangover symptoms have been associated with the greatest neural abnormalities during adolescence, particularly in frontal, parietal, and temporal regions.

    Physiological dependence and associated withdrawal episodes are thought to constitute a motivational force that sustains alcohol use and abuse and may contribute to relapse in dependent individuals. Although no animal model duplicates alcoholism, models for specific factors, like withdrawal, are useful for identifying potential genetic and neural determinants of liability in humans. Previously, we identified a quantitative trait locus (QTL) and gene (Mpdz, which encodes the multi-PDZ domain protein) on chromosome 4 with a large effect on alcohol withdrawal in mice. Using congenic mice that confirm this QTL and c-Fos expression as a high-resolution marker of neuronal activation, we report that congenic mice demonstrate significantly less neuronal activity associated with alcohol withdrawal in the rostroventral caudate putamen (rvCP), but not other parts of the striatum, compared with background strain mice. Moreover, bilateral rvCP lesions significantly increase alcohol withdrawal severity. Using retrograde (fluorogold) and anterograde (Texas Red conjugated dextran amine) tract tracing, we found that ~25% of c-Fos immunoreactive rvCP neurons project to caudolateral substantia nigra pars reticulata (clSNr), which we previously found is crucially involved in withdrawal following acute and repeated alcohol exposure. Our results expand upon work suggesting that this QTL impacts alcohol withdrawal via basal ganglia circuitry associated with limbic function, and indicate that an rvCP-clSNr projection plays a critical role. Given the growing body of evidence that the syntenic region of human chromosome 9p and MPDZ are associated with alcohol abuse, our results may facilitate research on alcohol dependence and associated withdrawal in clinical populations.

    Introduction In the general population, alcohol use disorder and depression more often occur together than any other combination of a mental illness with a substance use disorder. It is important to have a cost-effective intervention that is able to reach at-risk individuals in the early stages of developing alcohol use disorders and depression disorders. Methods and analysis This paper presents the protocol for a 3-arm multicentre randomised controlled trial (RCT) to test the efficacy and cost-effectiveness of the combined internet-based self-help intervention Take Care of You (TCOY) to reduce alcohol misuse and depression symptoms in comparison with a waiting list control group and a comparable intervention focusing on problematic alcohol use only. The active interventions consist of modules designed to reduce alcohol use, based on the principles of motivational interviewing and methods of cognitive behavioural therapy, together with additional modules in the combined study arm to reduce symptoms of depression. Data will be collected at baseline, as well as at 3 and 6 months postrandomisation. The primary outcome is the quantity of alcohol used in the past 7 days. A number of secondary outcome measures will be studied. These include the Centre of Epidemiologic Studies of Depression Scale (CES-D) and a combined measure with the criteria of values below the cut-off for severe alcohol use disorder and for CES-D. Data analysis will follow the intention-to-treat principle using (generalised) linear mixed models. In order to investigate the interventions’ cost-utility and cost-effectiveness, a full economic evaluation will be performed. Ethics and dissemination This RCT will be executed in compliance with the Helsinki Declaration and has been approved by 2 local Ethics Committees. Results will be reported at conferences and in peer-reviewed publications. Participant-friendly summaries of trial findings will be published on the TCOY websites. Trial registration

    2011-01-01

    Background Alcohol dependence during withdrawal and also in abstinent period in many cases is related to reduced inhibitory functions and kindling that may appear in the form of psychosensory symptoms similar to temporal lobe epilepsy frequently in conditions of normal EEG and without seizures. Because temporal lobe epileptic activity tend to spread between hemispheres, it is possible to suppose that measures reflecting interhemispheric information transfer such as electrodermal activity (EDA) might be related to the psychosensory symptoms. Methods and Findings We have performed measurement of bilateral EDA, psychosensory symptoms (LSCL-33) and alcohol craving (ACQ) in 34 alcohol dependent patients and 32 healthy controls. The results in alcohol dependent patients show that during rest conditions the psychosensory symptoms (LSCL-33) are related to EDA transinformation (PTI) between left and right EDA records (Spearman r = 0.44, p<0.01). Conclusions The result may present potentially useful clinical finding suggesting a possibility to indirectly assess epileptiform changes in alcohol dependent patients. PMID:21541318

  2. Human GABAA receptor alpha 1 and alpha 3 subunits genes and alcoholism.

    PubMed

    Parsian, A; Cloninger, C R

    1997-05-01

    gamma-Aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the brain. GABA effects are largely mediated by binding to the postsynaptic GABAA receptor, causing the opening of an integral chloride-ion channel. The GABAA antagonists picrotoxin and bicuculline reduce some ethanol-induced behaviors, such as motor impairment, sedation, and hypnosis. The role of this receptor in alcoholism is further supported by effective alleviation of alcohol withdrawal symptoms by GABAA agonists. To determine the role of the GABAA receptor (GABR) genes in the development of alcoholism, we have used alpha 1 and alpha 3 simple sequence repeat polymorphisms in a sample of unrelated alcoholics, alcoholic probands with both parents, and psychiatrically normal controls. For the GABR alpha 1 gene, the differences between allele frequencies, when all alleles were compared together, were not significant between total alcoholics, subtypes of alcoholics, and normal controls. However, for GABR alpha 3, the differences between total alcoholics and normal controls were significant when all alleles were compared together. The differences between subtypes of alcoholics and normal controls were not significant. The results of haplotype relative risk analysis for both genes, GABR alpha 1 and GABR alpha 3, were also negative. It is possible that the sample size in the haplotype relative risk is too small to have power to detect the differences in transmitted versus nontransmitted alleles. There is a need for a replication study in a large family sample that will allow haplotype relative risk or affected sib-pair analysis.

  9. Insomnia related to biperiden withdrawal in two schizophrenic patients.

    PubMed

    Hirose, S

    2000-11-01

    It is not uncommon for patients who are receiving antipsychotic medication to be given anticholinergic agents, such as biperiden, despite the relative absence of neurological side-effects. Two cases of schizophrenia are reported in which insomnia developed after biperiden withdrawal or reduction. The insomnia continued until biperiden treatment was reinstated, despite the fact that the patients did not exhibit signs or report symptoms indicative of antipsychotic drug-induced neurological side-effects. The occurrence of insomnia following the withdrawal of biperiden or reduction in the dose has not been previously reported. One potential explanation for the insomnia is cholinergic rebound following the withdrawal of biperiden.

    New drugs of abuse continue to emerge, including synthetic cannabinoids, synthetic cathinones, and hallucinogens. It is important to recognize their individual psychopharmacologic properties, symptoms of intoxication, and symptoms of withdrawal. Providers must be vigilant of acute medical or psychiatric complications that may arise from use of these substances. Treatment of the patient also includes recognition of any substance use disorders as well as comorbid psychiatric disorders. Although pharmacologic treatments for substance use disorder (of the drugs included in this article) are limited, there are a variety of psychotherapeutic modalities that may be of some benefit.

    2016-01-01

    Introduction: Craving is recognized as a formidable barrier in the management of patients with alcohol dependence. Among pharmacological agents that have been used in experimental studies for reduction in craving, baclofen appears to have a significant advantage over other agents. Methodology: The study is retrospective chart review of patients (n = 113) who have been treated with baclofen for alcohol dependence in a tertiary hospital of North India. Baseline assessments included sociodemography, motivation, quantity-frequency of alcohol use, and other alcohol-related clinical parameters. Weekly assessments, for a period of 4 weeks, were extracted from records which included dose of baclofen, craving intensity, and alcohol consumption. Results: The study sample was predominantly male, mean age of 41.49 (±9.75) years, most having a family history of substance use (70.97%), and many reporting binge use pattern in last year (49.46%). Baseline assessment revealed 48.7% of the sample was in precontemplation phase for alcohol use and 70% reported severe and persistent craving. This persistent craving was reported by only 15% of the sample by the end of 4 weeks treatment with baclofen (20–40 mg/day). Thirty-four percent of patients reported continued problematic use of alcohol by the end of 4 weeks. Conclusion: Our clinical experience suggests that baclofen reduces craving and alcohol consumption including in those with poor motivation. The drug causes few side effects and does not add to the intoxication effect of alcohol. Considering that baclofen is safe in those with liver cirrhosis and reduces withdrawal symptoms due to alcohol, a controlled trial comparing it with standard treatment is required. PMID:28163402

  14. Molecular mechanisms of synaptic remodeling in alcoholism.

    PubMed

    Kyzar, Evan J; Pandey, Subhash C

    2015-08-05

    Alcohol use and alcohol addiction represent dysfunctional brain circuits resulting from neuroadaptive changes during protracted alcohol exposure and its withdrawal. Alcohol exerts a potent effect on synaptic plasticity and dendritic spine formation in specific brain regions, providing a neuroanatomical substrate for the pathophysiology of alcoholism. Epigenetics has recently emerged as a critical regulator of gene expression and synaptic plasticity-related events in the brain. Alcohol exposure and withdrawal induce changes in crucial epigenetic processes in the emotional brain circuitry (amygdala) that may be relevant to the negative affective state defined as the "dark side" of addiction. Here, we review the literature concerning synaptic plasticity and epigenetics, with a particular focus on molecular events related to dendritic remodeling during alcohol abuse and alcoholism. Targeting epigenetic processes that modulate synaptic plasticity may yield novel treatments for alcoholism.

    Reports of symptoms when regular caffeine consumption is stopped have appeared in the medical literature, but the frequency and significance of this phenomenon have remained controversial. The objective of this study was to collect information on the prevalence and severity of caffeine withdrawal in the general population and determine the incidence and type of symptoms reported on blind abrupt and gradual caffeine cessation among coffee drinkers reporting past episodes of caffeine-withdrawal symptoms. A community-based telephone survey was followed by a stratified, randomized, double-blind controlled study. Participants included 11,112 persons spontaneously calling to inquire about studies not related to caffeine and 57 regular caffeine users selected from among the callers because of self-reported caffeine-withdrawal symptoms. Gradual or abrupt withdrawal from caffeine was compared to continuation of the same caffeine level. In a survey of 11,112 persons, 61% reported daily caffeine consumption, and 11% of the caffeine consumers reported symptoms upon stopping caffeine. Among the regular caffeine users, only 0.9% of males and 5.5% of females reported symptoms significant enough to interfere with normal activities when they abruptly stopped caffeine. A group of those reporting withdrawal symptoms were randomly assigned to three subsamples. In the group subjected to abrupt withdrawal (N = 18), 6 (33.3%) reported symptoms (e.g., headaches and tiredness). Including decreases in functional ratings, a total of 7 of the 18 (38.8%) could be considered to have experienced caffeine withdrawal. The gradual withdrawal group (N = 20) reported minimal if any caffeine withdrawal symptoms. A third group (N = 18) was kept on a level dose of caffeine for comparison. When participants are unaware of the caffeine-withdrawal focus of the study, these results suggest that both the frequency and severity of caffeine-withdrawal symptoms are much lower than found in some previous reports

  1. A 'crash' course on psychostimulant withdrawal as a model of depression.

    PubMed

    2002-10-01

    Most drugs of abuse generate diverse behavioral and neurochemical effects in mammals. However, one feature common to many such drugs is the phenomenon of the withdrawal syndrome that results from termination of drug administration. Early drug withdrawal, often referred to as the 'crash' phase in humans, is characterized by adverse psychological and/or somatic symptoms. Withdrawal from psychostimulant drugs precipitates a transient and primarily psychological condition that bears remarkable similarity to the symptoms of major depressive disorder in humans. Rodent paradigms of psychostimulant withdrawal faithfully model the human condition. Associated behavioral deficits in these animals can be reversed by treatments with antidepressant properties, suggesting that psychostimulant withdrawal might provide the basis for an animal model of depression. Current advances and limitations in the development of this model, together with recent evidence that psychostimulant withdrawal in rodents can be used to screen for novel, rapidly acting antidepressant treatments, are discussed.

    Objective: Alcohol-dependent patients in early abstinence show an impairment of cognitive functions which can be seen in poor implementation of newly learned skills for avoiding relapse. Executive dysfunction may persist during abstinence in alcohol-dependent persons, thus mitigating long-term abstinence. This study assessed visual memory function and choice of organizational strategies in alcoholics, as these are major factors necessary to implement ongoing behavior changes which are required for maintaining abstinence. Methods: We investigated 25 severely alcohol-dependent male patients between days 7 to 10 of abstinence, immediately after clinical withdrawal symptoms have ceased, compared to 15 healthy age, sex, and education matched controls. Pharmacological therapy had been terminated at least four half-lifes before inclusion into the study. Visual perceptual learning and organizational strategies were assessed with the Rey-Osterrieth Complex Figure Test (R-OCF). Results: There were no group differences in copying or recalling the figure, but time differences occurred. Alcoholics and healthy controls performed worse in recalling than in copying. But, alcoholics used less effective organizational strategies. Conclusions: There was a deficit in choice of organizational strategy in newly abstinent and unmedicated alcohol-dependent patients. Due to the imperfect organizational strategies, alcoholics might need auxiliary therapeutic care to strengthen their cognitive ability. PMID:21160546

    Alcohol use disorders (AUDs) are a major public health issue and have an enormous social and economic burden in developed, developing, and third-world countries. Current pharmacotherapies for treating AUDs suffer from deleterious side effects and are only effective in preventing relapse in a subset of individuals. This signifies an essential need for improved medications to reduce heavy episodic drinking and alcohol-related problems. Growing literature has provided support for the use of anticonvulsants in suppressing symptoms induced by alcohol withdrawal. Emerging clinical and preclinical evidence suggests that a number of well-tolerated anticonvulsants may also decrease alcohol drinking. This review will focus on recent evidence supporting the efficacy of novel anticonvulsants in reducing voluntary alcohol consumption in rodent models. The data demonstrate that anticonvulsants reduce drinking in standard home cage two-bottle choice paradigms, self-administration of alcohol in operant chambers, and cue- and stress-induced reinstatement of alcohol seeking behaviors in rats and mice. This review also highlights evidence that some anticonvulsants were only moderately effective in reducing drinking in select strains of rodents or models. This suggests that genetics, possible neuroadaptations, or the pharmacological target affect the ability of anticonvulsants to attenuate alcohol consumption. Nonetheless, anticonvulsants are relatively safe, have little abuse potential, and can work in combination with other drugs. The results from these preclinical and clinical studies provide compelling evidence that anticonvulsants are a promising class of medication for the treatment of AUDs.

    On isolated rat brains we studied native EEC and its derivates (mean EEC amplitude and power spectrums - Fourier transformation) during perfusion with ethanol (65 Mm/ L) and after its withdrawal. Previously rats were undergone ethanol burden for 6 days according to Majchrowicz procedures to get alcohol withdrawal syndrome. Duration perfusion without ethanol was 5, 10 and 20 min depending on the experimental schedule. Ethanol infusion between periods of withdrawal comprised 20 min. 55% of isolated brains shown epileptiform activity after 1-2 min of ethanol withdrawal but others manifested only increased mean amplitude and the power spectrums of EEC as well as an appearance of single or batch spikes. Differences between in vivo and in vitro conditions can be explained by the accelerated rate of ethanol elimination. The high positive correlation was obtained between EEC findings at the 5-th min of the first ethanol withdrawal and the same findings at the 5-th min of ethanol withdrawal in the second and the third episodes of ethanol withdrawal. Prolongation of withdrawal period more than 5th min caused brain death showing epileptiform activity. Isolated rat brain is the convenient subject to study pathogenesis of excitability of neurons and examination of drugs to treat alcohol withdrawal syndrome.

  6. Neuroticism and Conscientiousness as Moderators of the Relation Between Social Withdrawal and Internalizing Problems in Adolescence.

    Social withdrawal, or refraining from social interaction in the presence of peers, places adolescents at risk of developing emotional problems like anxiety and depression. The personality traits of neuroticism and conscientiousness also relate to emotional difficulties. For example, high conscientiousness predicts lower incidence of anxiety disorders and depression, while high neuroticism relates to greater likelihood of these problems. Based on these associations, socially withdrawn adolescents high in conscientiousness or low in neuroticism were expected to have lower levels of anxiety and depressive symptoms. Participants included 103 adolescents (59 % female) who reported on their personality traits in 8th grade and their anxiety and depressive symptoms in 9th grade. Peer ratings of social withdrawal were collected within schools in 8th grade. A structural equation model revealed that 8th grade withdrawal positively predicted 9th grade anxiety and depressive symptoms controlling for 8th grade anxiety and depressive symptoms, but neuroticism did not. Conscientiousness moderated the relation of withdrawal with depressive symptoms but not anxiety, such that high levels of conscientiousness attenuated the association between withdrawal and depressive symptoms. This buffering effect may stem from the conceptual relation between conscientiousness and self-regulation. Conscientiousness did not, however, moderate the association between withdrawal and anxiety, which may be partly due to the role anxiety plays in driving withdrawal. Thus, a conscientious, well-regulated personality partially protects withdrawn adolescents from the increased risk of emotional difficulties.

  7. Chronic alcohol exposure alters transcription broadly in a key integrative brain nucleus for homeostasis: the nucleus tractus solitarius.

    Chronic exposure to alcohol modifies physiological processes in the brain, and the severe symptoms resulting from sudden removal of alcohol from the diet indicate that these modifications are functionally important. We investigated the gene expression patterns in response to chronic alcohol exposure (21-28 wk) in the rat nucleus tractus solitarius (NTS), a brain nucleus with a key integrative role in homeostasis and cardiorespiratory function. Using methods and an experimental design optimized for detecting transcriptional changes less than twofold, we found 575 differentially expressed genes. We tested these genes for significant associations with physiological functions and signaling pathways using Gene Ontology terms and the Kyoto Encyclopedia of Genes and Genomes (KEGG) database, respectively. Chronic alcohol exposure resulted in significant NTS gene regulation related to the general processes of synaptic transmission, intracellular signaling, and cation transport as well as specific neuronal functions including plasticity and seizure behavior that could be related to alcohol withdrawal symptoms. The differentially expressed genes were also significantly enriched for enzymes of lipid metabolism, glucose metabolism, oxidative phosphorylation, MAP kinase signaling, and calcium signaling pathways from KEGG. Intriguingly, many of the genes we found to be differentially expressed in the NTS are known to be involved in alcohol-induced oxidative stress and/or cell death. The study provides evidence of very extensive alterations of physiological gene expression in the NTS in the adapted state to chronic alcohol exposure.

    N-acetylcysteine (NAC), a glutamate-modulating agent with antioxidant and anti-inflammatory properties, has been considered as a potential anti-addictive drug. Beneficial effects were reported for cocaine, cannabis, and tobacco addicts, but the effect of NAC in alcoholics or in alcohol animal models is unknown. The aggravation of alcohol withdrawal symptoms, such as anxiety, has been associated with increased levels of serum corticosterone and leptin. Thus, the aim of this study was to assess the effects of NAC on anxiety, as well as corticosterone and leptin serum levels, after cessation of chronic alcohol treatment in rats. Male Wistar rats were treated with 2 g/kg ethanol, twice daily, by gavage for 30 days; control animals received an appropriate dose of glucose to balance caloric intake. Rats were treated for 4 days with NAC (60 and 90 mg/kg, intra-peritoneally [i.p.]) or saline after alcohol cessation. Twenty-four hours after the last treatment, rats were exposed to a 5-min session in the open-field test (OF). Corticosterone and leptin serum levels were determined by ELISA in samples collected within 30 min after the OF. Results showed that rats were hypoactive (decreased rearing, peripheral, and total crossings), and that corticosterone and leptin levels were increased 5 days after alcohol cessation. Four days of NAC prevented the behavioral and biochemical changes brought about by alcohol cessation. We suggest that, in addition to the anti-addictive properties reported for other drugs of abuse, NAC is potentially useful in the management of alcohol withdrawal.

    Nicotine use is common among people with posttraumatic stress disorder (PTSD). Resilience, which is reflected in one's ability to cope with stress, has been shown to be associated with lower cigarette smoking and posttraumatic stress symptoms, but relationships among these three variables have not been examined. This study investigates the relationships of resilience and nicotine withdrawal with each other and in relation to PTSD symptoms. Participants were 118 cigarette smokers with PTSD seeking treatment for PTSD and nicotine use. Data were randomly cross-sectionally sampled from three time points: week 0, week 12, and week 27 of the study. Hierarchical multiple regression analyses revealed main effects of both resilience and nicotine withdrawal symptoms on PTSD severity, controlling for the sampled time point, negative affect, and expired carbon monoxide concentration. Consistent with prior research, PTSD severity was higher among individuals who were less resilient and for those who had greater nicotine withdrawal. There was an interaction between resilience and nicotine withdrawal on self-reported PTSD severity, such that greater resilience was associated with lower PTSD severity only among participants with low nicotine withdrawal symptoms. Among individuals with high nicotine withdrawal, PTSD severity was high, regardless of resilience level. These results suggest that resilience is a protective factor for PTSD severity for those with low levels of nicotine withdrawal, but at high levels of nicotine withdrawal, the protective function of resilience is mitigated.

  16. Alcohol disrupts sleep homeostasis.

    PubMed

    Thakkar, Mahesh M; Sharma, Rishi; Sahota, Pradeep

    2015-06-01

    Alcohol is a potent somnogen and one of the most commonly used "over the counter" sleep aids. In healthy non-alcoholics, acute alcohol decreases sleep latency, consolidates and increases the quality (delta power) and quantity of NREM sleep during the first half of the night. However, sleep is disrupted during the second half. Alcoholics, both during drinking periods and during abstinences, suffer from a multitude of sleep disruptions manifested by profound insomnia, excessive daytime sleepiness, and altered sleep architecture. Furthermore, subjective and objective indicators of sleep disturbances are predictors of relapse. Finally, within the USA, it is estimated that societal costs of alcohol-related sleep disorders exceeds $18 billion. Thus, although alcohol-associated sleep problems have significant economic and clinical consequences, very little is known about how and where alcohol acts to affect sleep. In this review, we have described our attempts to unravel the mechanism of alcohol-induced sleep disruptions. We have conducted a series of experiments using two different species, rats and mice, as animal models. We performed microdialysis, immunohistochemical, pharmacological, sleep deprivation and lesion studies which suggest that the sleep-promoting effects of alcohol may be mediated via alcohol's action on the mediators of sleep homeostasis: adenosine (AD) and the wake-promoting cholinergic neurons of the basal forebrain (BF). Alcohol, via its action on AD uptake, increases extracellular AD resulting in the inhibition of BF wake-promoting neurons. Since binge alcohol consumption is a highly prevalent pattern of alcohol consumption and disrupts sleep, we examined the effects of binge drinking on sleep-wakefulness. Our results suggest that disrupted sleep homeostasis may be the primary cause of sleep disruption observed following binge drinking. Finally, we have also shown that sleep disruptions observed during acute withdrawal, are caused due to impaired

    Development of medications that attenuate symptoms of nicotine withdrawal may be useful for facilitating smoking cessation. The neuropeptide oxytocin (OXY) decreases withdrawal signs and other addiction-related effects of several drugs of abuse in animals, but has not been examined in a preclinical model of nicotine addiction. The goal of this study was to examine the effects of OXY on nicotine withdrawal in rats, measured as increases in somatic signs and elevations in intracranial self-stimulation (ICSS) thresholds (anhedonia-like behavior) during antagonist-precipitated withdrawal from a chronic nicotine infusion. Effects of OXY on baseline ICSS thresholds in non-dependent rats were also evaluated. OXY (0.06 - 1.0mg/kg, i.p.) blocked withdrawal-induced elevations in somatic signs in nicotine-dependent rats without affecting somatic signs in non-dependent rats. In contrast, OXY did not affect nicotine withdrawal-induced elevations in ICSS thresholds. Relatively high doses of OXY (0.75 or 2.0mg/kg) elevated baseline ICSS thresholds in non-dependent rats. These findings demonstrate that OXY blocks somatic signs but not elevations in ICSS thresholds during antagonist-precipitated nicotine withdrawal. The ability of higher OXY doses to elevate baseline ICSS thresholds in non-dependent rats may reflect an aversive and/or motoric effect. These data suggest that OXY-based medications may be useful for treating the somatic component of the nicotine withdrawal syndrome, but may not be effective in attenuating withdrawal-induced anhedonia.

    Family, twin, and adoption studies have demonstrated that genes play an important role in the development of alcoholism. We investigated the association between alcoholism and the genetic polymorphisms of the GABAA receptor genes on chromosome 5q33-34 in Korean population. The genotype of the GABAA receptor gene polymorphisms were determined by performing polymerase chain reaction genotyping for 172 normal controls and 162 male alcoholics who are hospitalized in alcoholism treatment institute. We found a significant association between the genetic polymorphisms of the GABAA alpha1 and GABAA alpha6 receptor gene and alcoholism. The GG genotype of the GABAA alpha1 receptor gene was associated with the onset age of alcoholism and alcohol withdrawal symptoms, and a high score on the Korean version of the ADS. However, there was no association between the genetic polymorphisms of the GABAA beta2 and gamma2 receptor gene and alcoholisms. Our finding suggest that genetic polymorphisms of the GABAA alpha1 and GABAA alpha6 receptor gene may be associated with the development of alcoholism and that the GG genotype of the GABAA alpha1 receptor gene play an important role in the development of the early onset and the severe type of alcoholism.

    A 41-year-old male with a previous orthotopic liver transplant began experiencing insomnia, anxiety, diaphoresis, headaches, and palpitations that progressed over a 2-day period. As part of his home medication regimen, the patient was taking gabapentin for peripheral neuropathy. His acute onset of increasing symptoms coincided with an inadvertent discontinuation of gabapentin. After reinitiation of gabapentin therapy, the symptoms slowly improved over the next 24 hours and the episode of gabapentin withdrawal syndrome resolved.

    Cocaine-exposed planarians displayed abstinence-induced withdrawal behavior when placed into cocaine-free, but not cocaine-containing, water. The effect, manifested and quantified using a new spontaneous locomotor velocity metric, was dose-dependently related to cocaine exposure (8x10(-9) to 8x10(-5) M). Ultraviolet light (254 nm=7.83x10(-19) J), which was previously shown to interfere with drug-receptor interactions in Planaria, enhanced the abstinence-induced decreased locomotor velocity.

    The effects of alcoholism on cognitive and motor functioning are heterogeneous. While the role of some factors (patterns of alcohol consumption, eating habits or associated liver disease) has been hypothesized, the origins of this heterogeneity remain difficult to establish. The goals of the present study were thus to identify the clinical and biological risk factors for alcohol-related neuropsychological impairments and to determine the threshold beyond which these risk factors can be considered significant. Thirty alcoholic patients and 15 healthy controls had a blood test and underwent a neuropsychological examination. Alcohol severity measures, and liver, thiamine and malnutrition variables, were included in logistic regression models to determine the risk factors for cognitive and motor impairments (executive functions, visuospatial abilities, verbal episodic memory, ataxia), as well as those related to the severity of patients’ overall neuropsychological profile (moderate or severe impairments). Liver fibrosis was found to be a risk factor for executive impairments and also for ataxia, when it was associated with long-term alcohol misuse and symptoms of withdrawal. Altered thiamine metabolism was solely predictive of verbal episodic memory impairments. This combination of biological abnormalities was associated with a profile of moderate neuropsychological impairments. Malnutrition was associated with a profile of more severe impairments. Malnutrition, altered liver function and thiamine metabolism explain, at least partially, the heterogeneity of alcohol-related neuropsychological impairments. Our findings could allow clinicians to identify patients at particular risk of severe neuropsychological impairments before the onset of irreversible and debilitating neurological complications.

    We report the case of a woman with a history of chronic alcohol abuse who was hospitalized with diarrhea, severe hypokalemia refractory to potassium infusion, nausea, vomiting, abdominal pain, alternations of high blood pressure with phases of hypotension, irritability and increased urinary 5-hydroxyindoleacetic acid and cortisol. Although carcinoid syndrome was hypothesized, abdominal computed tomography and colonoscopy showed non-specific inflammatory bowel disease with severe colic wall thickening, and multiple colic biopsies confirmed non-specific inflammation with no evidence of carcinoid cells. During the following days diarrhea slowly decreased and the patient's condition progressively improved. One year after stopping alcohol consumption, the patient was asymptomatic and serum potassium was normal. Chronic alcohol exposure is known to have several deleterious effects on the intestinal mucosa and can favor and sustain local inflammation. Chronic alcohol intake may also be associated with high blood pressure, behavior disorders, abnormalities in blood pressure regulation with episodes of hypotension during hospitalization due to impaired baroreflex sensitivity in the context of an alcohol withdrawal syndrome, increased urinary 5-hydroxyindoleacetic acid as a result of malabsorption syndrome, and increased urinary cortisol as a result of hypothalamic-pituitary-adrenal axis dysregulation. These considerations, together with the regression of symptoms and normalization of potassium levels after stopping alcohol consumption, suggest the intriguing possibility of a alcohol-related acute inflammatory bowel disease mimicking carcinoid syndrome.

    Alcohol withdrawal is associated with affective-behavioral disturbances in both human alcoholics and in animal models. In general, these phenomena are potentiated by increased alcohol exposure duration and by prior withdrawal episodes. Previous studies have also reported locomotor hypoactivity during ethanol withdrawal in rats and mice, but only in novel test environments, not in the home-cage. In the present study, we examined the effects of withdrawal from chronic intermittent ethanol (CIE) vapor exposure on the level and circadian periodicity of wheel-running activity in C57BL/6J mice. CIE treatment resulted in reductions in wheel-running activity relative to plain-air controls that persisted for about one week after withdrawal. Analysis of circadian waveforms indicated that reduced activity occurred throughout the night phase, but that daily activity patterns were otherwise unaltered. CIE failed to alter free-running circadian period or phase in animals maintained under constant darkness. These results show that ethanol withdrawal can result in locomotor hypoactivity even in the habitual, home-cage environment, and suggest that withdrawal-related reductions in wheel-running activity may reflect the specific motivational significance of this behavior.

    1987-09-01

    This study evaluated 44 separate medication withdrawal periods in 17 subjects who were attending a hospital anticoagulation clinic for management of anticoagulation medication. The data suggest that when anticoagulant withdrawal is needed for particular dental procedures, a 2-day hold is an effective period of medication withdrawal. No thromboembolic events were observed after any of the withdrawal periods. Further, no posttreatment hemorrhagic episodes were observed when the anticoagulant medication was reinstituted after dental treatment. Prothrombin time blood levels should be determined in the immediate pretreatment period, however, because the prothrombin time can fluctuate even in the best maintained patients.

  9. Role of Altered Structure and Function of NMDA Receptors in Development of Alcohol Dependence

    PubMed Central

    Nagy, József; Kolok, Sándor; Boros, András; Dezső, Péter

    2005-01-01

    Long-term alcohol exposure gives rise to development of physical dependence on alcohol in consequence of changes in certain neurotransmitter functions. Accumulating evidence suggests that the glutamatergic neurotransmitter system, especially the N-methyl-D-aspartate (NMDA) type of glutamate receptors is a particularly important site of ethanol’s action, since ethanol is a potent inhibitor of the NMDA receptors (NMDARs) and prolonged ethanol exposition leads to a compensatory “upregulation” of NMDAR mediated functions supposedly contributing to the occurrence of ethanol tolerance, dependence as well as the acute and delayed signs of ethanol withdrawal. Recently, expression of different types of NMDAR subunits was found altered after long-term ethanol exposure. Especially, the expression of the NR2B and certain splice variant forms of the NR1 subunits were increased in primary neuronal cultures treated intermittently with ethanol. Since NMDA ion channels with such an altered subunit composition have increased permeability for calcium ions, increased agonist sensitivity, and relatively slow closing kinetics, the abovementioned alterations may underlie the enhanced NMDAR activation observed after long-term ethanol exposure. In accordance with these changes, the inhibitory potential of NR2B subunit-selective NMDAR antagonists is also increased, demonstrating excellent potency against alcohol withdrawal-induced in vitro cytotoxicity. Although in vivo data are few with these compounds, according to the effectiveness of the classic NMDAR antagonists in attenuation, not only the physical symptoms, but also some affective and motivational components of alcohol withdrawal, novel NR2B subunit selective NMDAR antagonists may offer a preferable alternative in the pharmacotherapy of alcohol dependence.

    It is well known that the controlled production of monodisperse simple and composite emulsions possesses uncountable applications in medicine, pharmacy, materials science and industry. Here we present both experiments and slender-body theory regarding the generation of simple emulsions using a configuration that we have called Confined Selective Withdrawal, since it is an improved configuration of the classical Selective Withdrawal. We consider two different situations, namely, the cases when the outer flow Reynolds number is high and low, respectively. Several geometrical configurations and a wide range of viscosity ratios are analyzed so that the physics behind the phenomenon can be fully understood. In addition, we present both experiments and theory regarding the generation of composite emulsions. This phenomenon is only feasible when the outer flow Reynolds number is low enough. In this case, we propose a more complex theory which requires the simultaneous resolution of two interfaces in order to predict the shape of the jet and the sizes of the drops formed. The excellent agreement between our slender-body approximation and the experimental evidence fully validates our theories.

    2013-01-01

    Drug tolerance and withdrawal are insidious responses to drugs of abuse; the first increases drug consumption while the second punishes abstention. Drosophila generate functional tolerance to benzyl alcohol sedation by increasing neural expression of the slo BK-type Ca2+ activated K+ channel gene. After drug clearance this change produces a withdrawal phenotype—increased seizure susceptibility. The drug-induced histone modification profile identified the 6b element (60 nt) as a drug responsive element. Genomic deletion of 6b produces the allele, sloΔ6b, that reacts more strongly to the drug with increased induction, a massive increase in the duration of tolerance, and an increase in the withdrawal phenotype yet does not alter other slo-dependent behaviors. The 6b element is a homeostatic regulator of BK channel gene expression and is the first cis-acting DNA element shown to specifically affect the duration of a drug action. PMID:24086565

    Despite their addictive potential, benzodiazepines belong to the most often prescribed drugs. We report on a patient with alprazolam dependence, who initially was treated with carbamazepine because of severe withdrawal symptoms. Due to liver enzyme elevation related to carbamazepine, we had to stop this treatment and instead of that started gabapentin treatment. Under this new therapy, the patient showed a dramatic relief of withdrawal symptoms and of the panic attacks recurring during withdrawal. Hence, due to their effectiveness and tolerability, newer anticonvulsants could be considered as medication for benzodiazepine withdrawal and as an alternative for benzodiazepine treatment in panic disorders.

  5. Psychostimulant withdrawal as an inducing condition in animal models of depression.

    Barr, Alasdair M; Markou, Athina

    2005-01-01

    A large body of evidence indicates that the withdrawal from high doses of psychostimulant drugs in humans induces a transient syndrome, with symptoms that appear isomorphic to those of major depressive disorder. Pharmacological treatment strategies for psychostimulant withdrawal in humans have focused mainly on compounds with antidepressant properties. Animal models of psychostimulant withdrawal have been shown to demonstrate a wide range of deficits, including changes in homeostatic, affective and cognitive behaviors, as well as numerous physiological changes. Many of these behavioral and physiological sequelae parallel specific symptoms of major depressive disorder, and have been reversed by treatment with antidepressant drugs. These combined findings provide strong support for the use of psychostimulant withdrawal as an inducing condition in animal models of depression. In the current review we propound that the psychostimulant withdrawal model displays high levels of predictive and construct validity. Recent progress and limitations in the development of this model, as well as future directions for research, are evaluated and discussed.

    A number of lines of evidence suggest that negative emotional symptoms of withdrawal involve reduced activity in the mesolimbic dopamine system. This study examined the contribution of dopaminergic signaling in structures downstream of the ventral tegmental area to withdrawal from acute morphine exposure, measured as potentiation of the acoustic startle reflex. Systemic administration of the general dopamine receptor agonist apomorphine or a cocktail of the D1-like receptor agonist SKF82958 and the D2-like receptor agonist quinpirole attenuated potentiated startle during morphine withdrawal. This effect was replicated by apomorphine infusion into the nucleus accumbens shell. Finally, apomorphine injection was shown to relieve startle potentiation during nicotine withdrawal and conditioned place aversion to morphine withdrawal. These results suggest that transient activation of the ventral tegmental area mesolimbic dopamine system triggers the expression of anxiety and aversion during withdrawal from multiple classes of abused drugs.

  8. Molecular basis of alcoholism.

    PubMed

    Most, Dana; Ferguson, Laura; Harris, R Adron

    2014-01-01

    Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy.

    The objective of this study was to determine the effect of memantine on schizophrenia-like symptoms in a ketamine-induced social withdrawal model in rats. We examined therapeutic effects of memantine, an NMDA antagonist, and haloperidol, a classic antipsychotic drug, on this behavioral model. Administration of memantine (10 or 15 mg·kg-1) significantly reduced ketamine-induced social withdrawal, and this effect was more effective than that of haloperidol (0.25 mg·kg-1) by restoring the social interaction between rats with no modification in general motor activity. These results suggest that memantine could have a therapeutic potential for schizophrenia. PMID:23585718

  10. Ectopic hippocampal neurogenesis in adolescent male rats following alcohol dependence.

    2014-07-01

    The adolescent hippocampus is highly vulnerable to alcohol-induced damage, which could contribute to their increased susceptibility to alcohol use disorder. Altered adult hippocampal neurogenesis represents one potential mechanism by which alcohol (ethanol) affects hippocampal function. Based on the vulnerability of the adolescent hippocampus to alcohol-induced damage, and prior reports of long-term alcohol-induced effects on adult neurogenesis, we predicted adverse effects on adult neurogenesis in the adolescent brain following abstinence from alcohol dependence. Thus, we examined neurogenesis in adolescent male rats during abstinence following a 4-day binge model of alcohol dependence. Bromodeoxyuridine and Ki67 immunohistochemistry revealed a 2.2-fold increase in subgranular zone cell proliferation after 7 days of abstinence. Increased proliferation was followed by a 75% increase in doublecortin expression and a 56% increase in surviving bromodeoxyuridine-labeled cells 14 and 35 days post-ethanol exposure, respectively. The majority of newborn cells in ethanol and control groups co-localized with NeuN, indicating a neuronal phenotype and therefore a 1.6-fold increase in hippocampal neurogenesis during abstinence. Although these results mirror the magnitude of reactive neurogenesis described in adult rat studies, ectopic bromodeoxyuridine and doublecortin positive cells were detected in the molecular layer and hilus of adolescent rats displaying severe withdrawal symptoms, an effect that has not been described in adults. The presence of ectopic neuroblasts suggests that a potential defect exists in the functional incorporation of new neurons into the existing hippocampal circuitry for a subset of rats. Age-related differences in functional incorporation could contribute to the increased vulnerability of the adolescent hippocampus to ethanol.

    This naturalistic telephone survey study compared perceptions of withdrawal severity in 67 daily cannabis users and 54 daily tobacco cigarette smokers who made quit attempts during the prior 30 days. A Withdrawal Symptom Checklist assessed the severity of abstinence symptoms and a Likert scale assessed perceived relations between abstinence symptoms and relapse. A composite Withdrawal Discomfort Score did not differ significantly between groups (M = 13.0 for cannabis, vs. M = 13.2 for tobacco). Individual symptom severity ratings were also of similar magnitude, except craving and sweating were slightly higher for tobacco. Both groups reported that withdrawal contributed substantially to relapse, and the strength of these ratings was similar across groups. The diverse convenience sample examined in this study adds external validity and generalizability to prior studies that included only users not planning to quit or excluded many common types of cannabis users. The comparable withdrawal experience from these heterogeneous cannabis and tobacco users supports previous findings from controlled laboratory studies and indicates that real-world, frequent cannabis users perceive that withdrawal symptoms negatively affect their desire and ability to quit.

    The aim of this study was to evaluate the effectiveness of opium tincture versus methadone syrup in the management of acute withdrawal syndrome in opium dependent patients during the detoxification period. In this double-blind randomized controlled study, a total of 74 adult male raw opium dependent patients were treated with opium tincture or methadone syrup 2 times daily for 5 consecutive days. Detoxification was initiated by tapered dose reductions to reach abstinence. At the end of the 10th day, the medications were discontinued. The Objective Opioid Withdrawal Scale was used to assess withdrawal symptoms every day. Significant decreases on the Objective Opioid Withdrawal Scale were found for both treatment methods during the study period (p < .0001). However, there was no significant difference between groups on the total Objective Opioid Withdrawal Scale, and adverse effects existed. Opium tincture can be considered as a potential substitute for methadone syrup for suppression of raw opium withdrawal symptoms, with minimal adverse effects.

    The upregulation of glutamatergic excitatory neurotransmission is thought to be partly responsible for the acute withdrawal symptoms and craving experienced by alcohol-dependent patients. Most physiological evidence supporting this hypothesis is based on data from animal studies. In addition, clinical data show that GABAergic and anti-glutamatergic drugs ameliorate withdrawal symptoms, offering indirect evidence indicative of glutamatergic hyperexcitability in alcohol-dependent subjects. We used proton magnetic resonance spectroscopy to quantify the glutamate (Glu) levels in healthy control subjects and in alcohol-dependent patients immediately after detoxification. The volumes of interest were located in the nucleus accumbens (NAcc) and the anterior cingulate cortex (ACC), which are two brain areas that have important functions in reward circuitry. In addition to Glu, we quantified the levels of combined Glu and glutamine (Gln), N-acetylaspartate, choline-containing compounds, and creatine. The Glu levels in the NAcc were significantly higher in patients than in controls. Craving, which was measured using the Obsessive Compulsive Drinking Scale, correlated positively with levels of combined Glu and Gln in the NAcc and in the ACC. The levels of all other metabolites were not significantly different between patients and controls. The increased Glu levels in the NAcc in alcohol-dependent patients shortly after detoxification confirm the animal data and suggest that striatal glutamatergic dysfunction is related to ethanol withdrawal. The positive correlation between craving and glutamatergic metabolism in both key reward circuitry areas support the hypothesis that the glutamatergic system has an important role in the later course of alcohol dependence with respect to abstinence and relapse.

    We report two serious and unusual complications of benzodiazepine withdrawal in a single patient: takotsubo cardiomyopathy and catatonia. This 61-year-old female patient was brought to the emergency department with lethargy and within hours had declined into a state of catatonia. Although there was never a complaint of chest pain, ECG showed deep anterior T-wave inversions and cardiac enzymes were elevated. An echocardiogram was consistent with takotsubo cardiomyopathy. She later received 1 mg of midazolam and within minutes had resolution of catatonic symptoms. Careful history revealed that she had omitted her daily dose of lorazepam for 3 days prior to admission. To our knowledge, the case presented herein is the first report of simultaneous catatonia and takotsubo cardiomyopathy in the setting of benzodiazepine withdrawal. The pathogenesis of both conditions is poorly understood but may be indirectly related to the sudden decrease in γ-aminobutyric acid (GABA) signaling during benzodiazepine withdrawal. PMID:27547472

    The present study explored the relationship between psychopathology and the experience of nicotine withdrawal among 191 adolescent smokers deprived of nicotine during a psychiatric hospitalization. Using methods based in item response theory, we demonstrated the ability of symptoms of nicotine withdrawal to cohere in measuring the withdrawal syndrome. After controlling for nicotine dependence, we found that several disorders showed significant but modest univariate relationships with individual withdrawal symptoms. After controlling for comorbidity with other disorders, we found that depressive and conduct disorders maintained significant but modest relationships with increased withdrawal severity. Item analyses across groups suggested that girls, individuals with a depressive disorder, and individuals with a conduct disorder tended to report higher levels of nicotine withdrawal but did not appear to inflate their scores because of disorder- or gender-specific reporting bias. Although levels of acute distress were related to withdrawal severity, the six-item withdrawal index showed good discriminant validity in this sample by demonstrating stronger correlations with craving and level of dependence than could be accounted for by levels of distress alone.

  18. Alcoholism: genes and mechanisms.

    PubMed

    Oroszi, Gabor; Goldman, David

    2004-12-01

    Alcoholism is a chronic relapsing/remitting disease that is frequently unrecognized and untreated, in part because of the partial efficacy of treatment. Only approximately one-third of patients remain abstinent and one-third have fully relapsed 1 year after withdrawal from alcohol, with treated patients doing substantially better than untreated [1]. The partial effectiveness of strategies for prevention and treatment, and variation in clinical course and side effects, represent a challenge and an opportunity to better understand the neurobiology of addiction. The strong heritability of alcoholism suggests the existence of inherited functional variants of genes that alter the metabolism of alcohol and variants of other genes that alter the neurobiologies of reward, executive cognitive function, anxiety/dysphoria, and neuronal plasticity. Each of these neurobiologies has been identified as a critical domain in the addictions. Functional alleles that alter alcoholism-related intermediate phenotypes include common alcohol dehydrogenase 1B and aldehyde dehydrogenase 2 variants that cause the aversive flushing reaction; catechol-O-methyltransferase (COMT) Val158Met leading to differences in three aspects of neurobiology: executive cognitive function, stress/anxiety response, and opioid function; opioid receptor micro1 (OPRM1) Asn40Asp, which may serve as a gatekeeper molecule in the action of naltrexone, a drug used in alcoholism treatment; and HTTLPR, which alters serotonin transporter function and appears to affect stress response and anxiety/dysphoria, which are factors relevant to initial vulnerability, the process of addiction, and relapse.

    Gatch, Michael B.; Nguyen, Jacques D.; Carbonaro, Theresa; Forster, Michael J.

    2011-01-01

    Aims Carisoprodol is a muscle relaxant that acts at the GABAA receptor. Concerns about the abuse liability of carisoprodol are increasing, but evidence that carisoprodol produces tolerance and a significant withdrawal syndrome has yet to be established. The purpose of the current study was to determine if repeated administration of carisoprodol produces tolerance and withdrawal signs in a mouse model. Methods Carisoprodol (0, 100, 200, 300, or 500 mg/kg bid, i.p.) was administered to Swiss-Webster mice for 4 days and loss-of-righting reflex was measured 20 to 30 minutes following each administration. On the fourth day, bemegride (20 mg/kg), flumazenil (20 mg/kg), or vehicle was administered following carisoprodol and withdrawal signs were measured. Separate groups of mice receiving the same treatment regimen and dose range were tested for spontaneous withdrawal at 6, 12 and 24 hr after the last dose of carisoprodol. Results The righting reflex was dose-dependently impaired following the first administration of carisoprodol. A 75 to 100% decrease in the magnitude of the impairment occurred over the four days of exposure, indicating the development of tolerance to the carisoprodol-elicited loss-of-righting reflex. Withdrawal signs were not observed within 24 hours following spontaneous withdrawal; however, bemegride and flumazenil each precipitated withdrawal within 15 to 30 min of administration. Conclusions Carisoprodol treatment resulted in tolerance and antagonist-precipitated withdrawal, suggesting it may have an addiction potential similar to that of other long-acting benzodiazepine or barbiturate compounds.

    Previous studies have shown that withdrawal from psychostimulant drugs such as d-amphetamine or methamphetamine decreases motivation to work for a natural reinforcement, which is thought to be associated with the withdrawal-induced depressive state and hypofunction of the mesolimbic dopamine system. However, to our knowledge, studies exploring the effect of morphine withdrawal on motivation for a natural reinforcement are lacking. The purpose of the present study was to examine whether motivation to work for a natural reinforcement changes during morphine withdrawal. Three groups of male Sprague-Dawley rats were trained to respond on a nose poke for a 4% sucrose solution under a progressive ratio schedule and were subsequently administered a 10-day regimen of injection of high or low dose of morphine or saline. Their duration of break point and withdrawal symptoms were assessed. The finding showed that break points were significantly reduced on day 1 and persisted to at least day 10 of withdrawal without change in locomotor activity. There were hardly any differences bear mentioning when comparing the magnitude of the decrease between the high- and the low-dose group, whereas the withdrawal scales were significant greater in the high-dose group than in the low-dose group. The results suggest that the morphine withdrawal resulted in decreased motivation to obtain the natural reinforcement. The progressive ratio procedure may be a useful technique for evaluation of changes in motivation for natural reinforcing stimuli following withdrawal from opiates.

    Background Alcohol-dependent patients usually experience negative affects under the influence of alcohol, and these affective symptoms have been shown to decrease as a result of alcohol-withdrawal treatment. A recent cognitive–affective model suggests an interaction between drug motivation and affective symptoms. The aim of this multicenter study was to evaluate the psychological changes in subjects undergoing a residential rehabilitation program specifically designed for alcohol addiction, and to identify at discharge patients with greater affective symptoms and therefore more at risk of relapse. Materials and methods The sample included 560 subjects (mean age 46.91±10.2 years) who completed 28-day rehabilitation programs for alcohol addiction, following a tailored routine characterized by short duration and high intensity of medical and psychotherapeutic treatment. The psychological clinical profiles of anxiety, depression, psychological distress, psychological well-being, and self-perception of a positive change were assessed using the Cognitive Behavioral Assessment – Outcome Evaluation questionnaire at the beginning and at the end of the program. The changes in the psychological variables of the questionnaire were identified and considered as outcome evaluation of the residential intervention. Moreover, differences in the psychological functioning between patients with different characteristics were investigated. Results The score measured by the Cognitive Behavioral Assessment – Outcome Evaluation showed significant improvements in all the psychological characteristics assessed, and the profile at discharge was within the normal scores. Some significant differences were found in relation to specific characteristics of the sample, such as age, sex, level of education, type of intervention, and polysubstance use. Conclusion This study shows the changes in psychological profile in subjects undergoing residential rehabilitation from alcohol and how this

  9. The role of GABA(A) receptors in the development of alcoholism.

    PubMed

    Enoch, Mary-Anne

    2008-07-01

    Alcoholism is a common, heritable, chronic relapsing disorder. GABA(A) receptors undergo allosteric modulation by ethanol, anesthetics, benzodiazepines and neurosteroids and have been implicated in the acute as well as the chronic effects of ethanol including tolerance, dependence and withdrawal. Medications targeting GABA(A) receptors ameliorate the symptoms of acute withdrawal. Ethanol induces plasticity in GABA(A) receptors: tolerance is associated with generally decreased GABA(A) receptor activation and differentially altered subunit expression. The dopamine (DA) mesolimbic reward pathway originating in the ventral tegmental area (VTA), and interacting stress circuitry play an important role in the development of addiction. VTA GABAergic interneurons are the primary inhibitory regulators of DA neurons and a subset of VTA GABA(A) receptors may be implicated in the switch from heavy drinking to dependence. GABA(A) receptors modulate anxiety and response to stress; important elements of sustained drinking and relapse. The GABA(A) receptor subunit genes clustered on chromosome 4 are highly expressed in the reward pathway. Several recent studies have provided strong evidence that one of these genes, GABRA2, is implicated in alcoholism in humans. The influence of the interaction between ethanol and GABA(A) receptors in the reward pathway on the development of alcoholism together with genetic and epigenetic vulnerabilities will be explored in this review.

  10. Cannabis Withdrawal, Posttreatment Abstinence, and Days to First Cannabis Use Among Emerging Adults in Substance Use Treatment: A Prospective Study

    2015-01-01

    Very little prospective research investigates how cannabis withdrawal is associated with treatment outcomes, and this work has not used the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) thresholds for cannabis withdrawal. The sample included 110 emerging adults entering outpatient substance use treatment who were heavy cannabis users with no other drug use and limited alcohol use. We used survival analyses to predict days to first use of cannabis and logistic regression to predict whether participants were abstinent and living in the community at 3 months. Those meeting criteria for cannabis withdrawal were more likely to return to use sooner than those not meeting criteria for cannabis withdrawal. However, the presence of cannabis withdrawal was not a significant predictor of 3-month abstinence. Emerging adults with DSM-5 cannabis withdrawal may have difficulty initiating abstinence in the days following their intake assessment, implying the need for strategies to mitigate their more rapid return to cannabis use.

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

    PubMed

    Saveika, Joseph A; Shelton, Jean E

    2007-12-01

    Intrathecal baclofen withdrawal syndrome is a known complication of intrathecal baclofen pumps. Its origin is postulated as an independent form of a serotonergic syndrome occurring from loss of gamma-aminobutyric acid B receptor-mediated inhibition of serotonin. Prodromal symptoms include pruritus, a return of deep tendon reflexes, and increased spastic hypertonia. Previous reports have documented use of cyproheptadine in treatment of this syndrome in adults with positive results. We present the case of a 14-yr-old child with cerebral palsy who developed pruritus and worsening spastic hypertonia 18 mos after pump implantation. She had been previously treated with 520 microg/day of intrathecal baclofen. Progression of her symptoms was successfully arrested by the administration of both oral and intrathecal baclofen and 6 mg of oral cyproheptadine every 6 hrs for 1 day. We postulate that cyproheptadine should be considered a valuable adjuvant therapy for treatment of suspected intrathecal baclofen withdrawal syndrome.

    Withdrawal from opioids leads to the expression of aversion behaviors. Previous studies have shown that the serotonergic system has an important role in morphine withdrawal syndrome. The 5-HT7 receptor is a recently discovered member of the 5-HT receptor family that has been shown to be involved in these behaviors. The aim of the present study was to test the role of the 5-HT7 receptor in withdrawal syndrome in morphine-dependent mice with AS19 and SB269970, a selective agonist and antagonist of this receptor, respectively. Dependence was induced by the repeated administration of morphine for five consecutive days. The morphine-dependent mice received AS19 (3, 5, or 10mg/kg, intraperitoneal) or SB269970 (1, 3, or 10mg/kg, intraperitoneal) 15 min prior to the precipitation of morphine withdrawal syndromes by naloxone (3mg/kg, subcutaneous). Withdrawal symptoms, including percent weight loss, jumping, teeth chattering, writhing, body and face grooming, sniffing, standing, and head and limb shaking, were recorded for 30 min after the naloxone injection. The morphine-dependent mice had significantly more withdrawal symptoms than naive control mice. The administration of AS19 reduced most of the morphine withdrawal symptoms. However, SB2699 increased some of the withdrawal symptoms, including teeth chattering, face grooming, jumping, and head and limb shaking. These findings suggest that the 5-HT7 receptor is involved in morphine withdrawal. Its activation decreased and its inactivation increased the morphine withdrawal syndrome. Further studies are recommended to better understand the role of the 5-HT7 receptor in morphine dependence and withdrawal.

    Psychological individual differences, such as personality, affectivity, and general mental ability, have been shown to predict numerous work-related behaviors. Although there is substantial research demonstrating relationships between psychological individual differences and withdrawal behaviors (i.e., lateness, absenteeism, and turnover), there is no integrative framework providing scholars and practitioners a guide for conceptualizing how, why, and under what circumstances we observe such relationships. In this integrative conceptual review we: (a) utilize the Cognitive-Affective Processing System framework (Mischel & Shoda, 1995) to provide an overarching theoretical basis for how psychological individual differences affect withdrawal behaviors; (b) create a theoretical model of the situated person that summarizes the existing empirical literature examining the effect of psychological differences on withdrawal behavior; and (c) identify future research opportunities based on our review and integrative framework.

  18. Cognitive control deficits during mecamylamine-precipitated withdrawal in mice: Possible links to frontostriatal BDNF imbalance

    Nicotine is a major psychoactive and addictive component of tobacco. Although cessation of tobacco use produces various somatic and affective symptoms, withdrawal-related cognitive deficits are considered to be a critical symptom that predict relapse. Therefore, delineating the cognitive mechanisms of nicotine withdrawal may likely provide gainful insights into the neurobiology of nicotine addiction. The present study was designed to examine the effects of nicotine withdrawal induced by mecamylamine, a non-specific nicotinic receptor (nAChR) antagonist, on cognitive control processes in mice using an operant strategy switching task. Brain-derived neurotrophic factor (BDNF) modulates synaptic transmission in frontostriatal circuits, and these circuits are critical for executive functions. Thus, we examined the effects of mecamylamine-precipitated nicotine withdrawal on prefrontal and striatal BDNF protein expression. Mice undergoing precipitated nicotine withdrawal required more trials to attain strategy switching criterion as compared to the controls. Error analysis indicated that impaired performance in these animals was mostly related to their inability to execute the new strategy. The striatal/prefrontal BDNF ratios robustly increased following precipitated nicotine withdrawal. Moreover, higher BDNF ratios were associated with longer task acquisition. Collectively, our findings illustrate that mecamylamine-induced nicotine withdrawal disrupts cognitive control processes and that these changes are possibly linked to perturbations in frontostriatal BDNF signaling.

  19. A drug-paired taste cue elicits withdrawal and predicts cocaine self-administration.

    Nyland, Jennifer E; Grigson, Patricia S

    2013-03-01

    Addiction is a chronic disease where periods of abstinence are riddled with instances of craving, withdrawal, and eventual relapse to escalated drug use. Cues previously associated with drug use can have a deleterious effect on this cycle by precipitating withdrawal symptoms. Here we focus specifically on the relationship between avoidance of a drug-paired taste cue and the ability of the drug-paired cue to elicit withdrawal and, ultimately, drug seeking and taking. We used a rat model of drug addiction and naloxone-induced loss of body weight to test whether a taste cue elicits withdrawal in anticipation of drug availability. Experiment 1 investigated the ability of a taste cue to elicit signs of withdrawal when it predicted experimenter-administered morphine (15 mg/kg, i.p.). In Experiment 2, a saccharin taste cue was paired with the opportunity to actively self-administer cocaine (0.167 mg/infusion, i.v.). The results show that presentation of a morphine- or cocaine-paired taste cue is sufficient to elicit naloxone-induced withdrawal symptoms, and greater withdrawal predicts greater cocaine self-administration in rats.

    Symptom control has become increasingly recognized as an important goal in patient care. In this article, advances in symptom assessment, and various definitions of symptom improvement are reviewed. Theoretical concepts underlying symptom control and clinically significant change are presented, as well as the role of symptom control as an endpoint in clinical trials. Symptom control is then surveyed in two broad categories for selected symptoms. The first area is therapy related symptoms, secondary to chemotherapy, radiation, hormonal therapy, and surgery. Symptoms reviewed include chemotherapy related mucositis, emesis, fatigue; hot flashes; and radiation related dermatitis, xerostomia, and mucositis. The second area is palliative oncologic approaches to disease-related symptoms. Results in palliative chemotherapy, palliative radiation therapy, cancer pain, and lack of appetite are summarized. Areas requiring further research are noted. Findings are presented in both a clinical and research context to help guide the reader with interpreting symptom control studies.

We tested the hypothesis that in order to precipitate withdrawal, opioids need to convert the inactive opioid receptor site via protein kinase C into a constitutively active form on which the antagonist precipitates withdrawal. Acute microg/kg), given for 6 days, which was followed by the antagonist naltrexone (20 microg/kg i.v.) in the awake trained canine (n = 10). Abrupt displacement of opioid binding resulted in acute withdrawal symptoms: increase in blood pressure, heart rate, increase in amplitude height of somatosensory evoked potential, reduced tolerance to colon distention and a significant increase in grading of vegetative variables (restlessness, panting, thrashing of the head, whining, yawning, gnawing, salivation and/or rhinorrhoea, mydriasis, stepping of extremities and vomiting). Following a washout period of 14 days, the same animals were given the highly specific protein kinase C inhibitor H7 (250 microg/kg) prior to the same dosages of sufentanil and naltrexone. Such pretreatment was able to either attenuate or completely abolish the acute withdrawal symptoms. The data suggest that for precipitation of withdrawal, intracellular phosphorylation is a prerequisite in order to activate the opioid mu-receptor. In such a setting, naltrexone acts like an 'inverse agonist' relative to the action of the antagonist on a non-preoccupied receptor site not being exposed previously to a potent opioid agonist.

    Clinical evidence suggests that individuals experiencing drug withdrawal can become conditioned to environmental situations, whereby previously neutral stimuli can produce symptoms of withdrawal. It is believed that this "conditioned withdrawal" can have motivational significance, but the neurobiological basis for conditioned withdrawal is unknown. The goal of this study was to determine adaptations in endogenous opioid systems that may be responsible for expression of conditioned withdrawal. Opioid-dependent rats trained to lever press for food were exposed to tone and scent cues in the presence of naloxone or saline. Naloxone but not saline predictably suppressed responding for food. One month later and in a post-dependent state, all rats again were exposed to the cues but not naloxone. The conditioned cues alone suppressed responding for food in the rats previously paired with naloxone, but no suppression was seen in rats previously paired with saline. Radioimmunoassay (RIA) analysis for nociceptin/orphanin FQ (nociceptin), met-enkephalin-Arg-Phe (MEAP), and dynorphin A (dyn A) was performed from dissections of various brain regions of the rats undergoing conditioned withdrawal. Significant reductions in nociceptin peptide levels were seen in the frontal cortex and olfactory tubercle of these rats. Unconditioned opioid withdrawal and unconditioned footshock stress produced different patterns of opioid peptide regulation in separate groups of rats. These results shed light on adaptations of endogenous opioid systems to conditioned cues, stress, and withdrawal, all factors that play a role in motivating drug intake.

    Increased anxiety is a prominent withdrawal symptom in abstinent smokers, yet the neuroanatomical and molecular bases underlying it are unclear. Here we show that withdrawal-induced anxiety increases activity of neurons in the interpeduncular intermediate (IPI), a subregion of the interpeduncular nucleus (IPN). IPI activation during nicotine withdrawal was mediated by increased corticotropin releasing factor (CRF) receptor-1 expression and signalling, which modulated glutamatergic input from the medial habenula (MHb). Pharmacological blockade of IPN CRF1 receptors or optogenetic silencing of MHb input reduced IPI activation and alleviated withdrawal-induced anxiety; whereas IPN CRF infusion in mice increased anxiety. We identified a mesointerpeduncular circuit, consisting of ventral tegmental area (VTA) dopaminergic neurons projecting to the IPN, as a potential source of CRF. Knockdown of CRF synthesis in the VTA prevented IPI activation and anxiety during nicotine withdrawal. These data indicate that increased CRF receptor signalling within a VTA-IPN-MHb circuit triggers anxiety during nicotine withdrawal.

    Topographic measures of electroencephalographic (EEG) amplitude were used to compare recovered alcoholics (n = 14) with sex- and age-matched control subjects. Delta, alpha, and beta activity did not distinguish the groups, but regional differences in theta distribution did. Recovered alcoholics showed more uniform distributions of theta amplitudes in bilateral anterior and posterior regions compared with controls. Because a minimum of 5 years had elapsed since the recovered alcoholic subjects fulfilled DSM-III-R criteria for alcohol abuse or dependence, it is unlikely these EEG theta differences reflect the effects of withdrawal.

    Withdrawal from long-term ethanol consumption results in overexcitation of glutamatergic neurotransmission in the amygdala, which induces an anxiety-like syndrome. Most alcoholics that suffer from such symptoms frequently depend on habitual drinking as self-medication to alleviate their symptoms. Metabotropic glutamate receptor subtype 5 (mGlu5) and protein kinase C (PKC) epsilon have been reported to mediate acute and chronic effects of ethanol. This study explores the changes in mGlu5 and PKC epsilon in the amygdala following acute administration of ethanol during ethanol withdrawal (EW) induced anxiety. Male Wistar rats were fed a modified liquid diet containing low-fat cow milk, sucrose, and maltodextrin, with a gradual introduction of 2.4%, 4.8% and 7.2% ethanol for 20 days. Six hours into EW, the rats were intraperitoneally injected with normal saline and ethanol (2.5 g/kg, 20% v/v), and exposed to open-field and elevated plus maze tests. Then, amygdala tissue was dissected from the rat brain for Western blot and gene expression studies. EW-induced anxiety was accompanied by a significant increase in mGlu5, total PKC epsilon, and phosphorylated PKC epsilon protein levels, and also of mRNA of mGlu5 (GRM5) in the amygdala. Acute administration of ethanol significantly attenuated EW-induced anxiety as well as an EW-induced increase in GRM5. The acute challenge of ethanol to EW rats had little effect on the phosphorylated and total protein levels of PKC epsilon in the amygdala. Our results demonstrate that amygdala PKC epsilon may not be directly involved in the development of anxiety following EW.

    Alcohol withdrawal syndrome (AWS) is a medical emergency situation which appears after abrupt cessation of ethanol intake. Decreased GABA-A function and increased glutamate function are known to exist in the AWS. However, the involvement of glutamate transporters in the context of AWS requires further investigation. In this study, we used a model of ethanol withdrawal involving abrupt cessation of binge ethanol administration (4 g/kg/gavage three times a day for three days) using male alcohol-preferring (P) rats. After 48 h of withdrawal, P rats were re-exposed to voluntary ethanol intake. The amount of ethanol consumed was measured during post-withdrawal phase. In addition, the expression of GLT-1, GLAST and xCT were determined in both medial prefrontal cortex (mPFC) and nucleus accumbens (NAc). We also measured glutamine synthetase (GS) activity, and the tissue content of glutamate, glutamine, dopamine and serotonin in both mPFC and NAc. We found that binge ethanol withdrawal escalated post-withdrawal ethanol intake, which was associated with downregulation of GLT-1 expression in both mPFC and NAc. The expression of GLAST and xCT were unchanged in the ethanol-withdrawal (EW) group compared to control group. Tissue content of glutamate was significantly lower in both mPFC and NAc, whereas tissue content of glutamine was higher in mPFC but unchanged in NAc in the EW group compared to control group. The GS activity was unchanged in both mPFC and NAc. The tissue content of DA was significantly lower in both mPFC and NAc, whereas tissue content of serotonin was unchanged in both mPFC and NAc. These findings provide important information of the critical role of GLT-1 in context of AWS.

    The aim of this paper was to provide insights into alcohol misuse within UK veterans to inform as to whether their presentations differ from the general public. This was done by exploring differences in the severity of alcohol misuse between UK veterans and the general public admitted to a general NHS hospital over an 18 month period using retrospective data. All patients admitted to the hospital were screened for alcohol misuse. Those deemed as experiencing problems were referred for specialist nurse-led support. A total of 2331 individuals were referred for this supported and administered with a standardised assessment that included measures of the severity of alcohol difficulties (AUDIT), dependency levels (LDQ), and assessed for the presence of withdrawal symptoms (CIWA-Ar). In addition, information was collected on service utilisation, referral category (medical or mental health), other substance misuse, and demographic characteristics. No differences were found between the severity of reported alcohol difficulties between veterans and non-veterans. Evidence was found to suggest that veterans were more likely to be referred for support with alcohol difficulties at an older age and to be admitted to hospital for longer periods of time. This could have considerable cost implications for the NHS. It was more common for veterans to present at hospital with physical health difficulties prior to being referred for support for alcohol.

    Treatment of alcohol dependence consist of alcohol detoxification with withdrawal alleviation and relapse prevention or maintenance therapy. Drugs of choice for alcohol withdrawal cure are benzodiazepines and anticonvulsants are an alternative for them. Relapse prevention and alcohol abuse alleviation are carried out using disulfiram, acamprosate, naltrexone and nalmefene. Moreover, therapeutic possibilities of memantine, gabapentine, pregabalin, baclofen, modafinil, ondansetron D-cycloserine and aripiprazole are studying nowadays. Use of selective serotonin reuptake inhibitors including fluvoxamine for alcohol patients is of great importance due to frequent comorbidity of alcoholism, depression and anxiety. There are some doubtful methods of alcoholism treatment accepted in Russian addictive medicine such as clearance detoxification and use of antipsychotics for craving elimination.

    To characterize the factors affecting the decision to withdraw from dialysis, the authors compared patients withdrawing from dialysis (n=62) with patients dying from all other causes (n=242) over 21 years (1976-1996) in a single dialysis unit. Compared with those who died from other causes, patients who withdrew were older (67+/-11 vs 61+/-11 years); were more likely to have severe physical impairment (87% vs 62%) and severe restriction of activities of daily living (77% vs 46%); and had higher frequencies of congestive heart failure (81 % vs 62%), myocardial infarction (60% vs 42%), peripheral vascular disease (71 % vs 40%), and diabetes mellitus (66% vs 36%) (p < or = 0.014). Dialysis modality; duration of dialysis; the degree of family support; index of disease severity; the use of tobacco, alcohol, or illicit drugs; and the frequency of ischemic heart disease, dysrhythmia, pericarditis, cardiac arrest, cerebrovascular accident, hypertension, obstructive lung disease, cancer, and human immunodeficiency virus did not differ between the two groups. Stepwise logistic regression showed that dialysis during 1990-1996, severe limitation of activities of daily living, and diabetes mellitus were independent risk factors for withdrawal. During 1990-1996, 44% of the deaths were caused by withdrawal from treatment. In addition to other factors, dialysis in the 1990s is a strong predictor of withdrawal from dialysis. The reasons for the increased rate of withdrawal from dialysis in recent years, and the effect of this increased rate of withdrawal on mortality, need further evaluation.

  13. The alpha2 adrenergic receptor antagonist idazoxan, but not the serotonin-2A receptor antagonist M100907, partially attenuated reward deficits associated with nicotine, but not amphetamine, withdrawal in rats.

    Based on phenomenological similarities between anhedonia (reward deficits) associated with drug withdrawal and the negative symptoms of schizophrenia, we showed previously that the atypical antipsychotic clozapine attenuated reward deficits associated with psychostimulant withdrawal. Antagonism of alpha(2) adrenergic and 5-HT(2A) receptors may contribute to these effects of clozapine. We investigated here whether blockade of alpha(2) or 5-HT(2A) receptors by idazoxan and M100907, respectively, would reverse anhedonic aspects of psychostimulant withdrawal. Idazoxan treatment facilitated recovery from spontaneous nicotine, but not amphetamine, withdrawal by attenuating reward deficits and increase the number of somatic signs. Thus, alpha(2) adrenoceptor blockade may have beneficial effects against nicotine withdrawal and may be involved in the effects of clozapine previously observed. M100907 worsened the anhedonia associated with nicotine and amphetamine withdrawal, suggesting that monotherapy with M100907 may exacerbate the expression of the negative symptoms of schizophrenia or nicotine withdrawal symptoms in people, including schizophrenia patients, attempting to quit smoking.

    Iatrogenic Cushing's syndrome is the most common form of hypercortisolism. Glucocorticoids are widely used for the treatment of various diseases, often in high doses that may lead to the development of severe hypercortisolism. Iatrogenic hypercortisolism is unique, as the application of exogenous glucocorticoids leads to the simultaneous presence of symptoms specific for hypercortisolism and the suppression of the endogenous hypothalamic-pituitary-adrenal axis. The principal question of its therapy is related to the problem of glucocorticoid withdrawal. There is considerable interindividual variability in the suppression and recovery of the hypothalamic-pituitary-adrenal axis, therefore, glucocorticoid withdrawal and substitution can only be conducted in a stepwise manner with careful clinical follow-up and regular laboratory examinations regarding endogenous hypothalamic-pituitary-adrenal axis activity. Three major complications which can be associated with glucocorticoid withdrawal are: i. reactivation of the underlying disease, ii. secondary adrenal insufficiency, iii. steroid withdrawal syndrome. Here, the authors summarize the most important aspects of this area based on their clinical experience and the available literature data.
