    Approaches to the development of medications for the treatment of methamphetamine dependence

    ADDICTION, Issue 2007
    Frank J. Vocci
    ABSTRACT Background Methamphetamine abuse has become an increasing problem in both the United States and globally with concomitant increases in adverse medical, social and environmental sequelae. Behavioral therapies have been used with some success to treat methamphetamine abusers and dependent individuals, but are not universally efficacious. Methamphetamine has a rich pharmacology that theoretically provides many opportunities for potential pharmacotherapeutic intervention. Nevertheless, there are no approved medications with an indication for treating methamphetamine abusers or addicts at this time. Aim To describe briefly how methamphetamine functions and affects function in brain and report how basic researchers and clinicians are attempting to exploit and exploiting this knowledge to discover and develop effective pharmacotherapies. Results Scientifically based approaches to medications development by evaluating medications that limit brain exposure to methamphetamine; modulate methamphetamine effects at vesicular monoamine transporter-2 (VMAT-2); or affect dopaminergic, serotonergic, GABAergic, and/or glutamatergic brain pathways that participate in methamphetamine's reinforcing effects are presented. Conclusion The evidence supports the rationale that pharmacotherapies to decrease methamphetamine use, or reduce craving during abstinence may be developed from altering the pharmacokinetics and pharmacodynamics of methamphetamine or its effects on appetitive systems in the brain.

    Concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) and AUDIT zones in defining levels of severity among out-patients with alcohol dependence in the COMBINE study

    ADDICTION, Issue 12 2006
    Dennis M. Donovan
    ABSTRACT Aims To examine among alcohol-dependent out-patient clients the concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) total score and ,zones' suggested by the World Health Organization for defining levels of severity of alcohol use problems. Design Participants were classified into AUDIT zones (AUDIT total score = 8,15, 16,19, 20,40) and compared on measures of demographics, treatment goals, alcohol consumption, alcohol-related consequences, severity of dependence, physiological dependence, tolerance, withdrawal and biomarkers of alcohol use. Setting Eleven out-patient academic clinical research centers across the United States. Participants Alcohol dependent individuals (n = 1335) entering out-patient treatment in the Combined Pharmacotherapies and Behavioral Interventions (COMBINE) study. Measurements The AUDIT was administered as part of an initial screening. Baseline measures used for concurrent validation included the Structured Clinical Interview for Diagnostic and Statistical Manual, 4th edition (DSM-IV) Disorders, the Alcohol Dependence Scale, the Drinker Inventory of Consequences, the Obsessive-Compulsive Drinking Scale, the University of Rhode Island Change Assessment, the Thoughts about Abstinence Scale, the Form-90, %carbohydrate-deficient transferrin and gamma-glutamyl transferase. Findings Indicators of severity of dependence and alcohol-related problems increased linearly with total score and differed significantly across AUDIT zones. The highest zone, with scores of 20 and above, was markedly different with respect to severity from the other two zones and members of this group endorsed an abstinence goal more strongly. Conclusions The AUDIT total score is a brief measure that appears to provide an index of severity of dependence in a sample of alcohol-dependent individuals seeking out-patient treatment, extending its potential utility beyond its more traditional role as a screening instrument in general populations.

    The Impact of Chronic Cigarette Smoking on Recovery From Cortical Gray Matter Perfusion Deficits in Alcohol Dependence: Longitudinal Arterial Spin Labeling MRI

    ALCOHOLISM, Issue 8 2009
    Anderson Mon
    Background:, Neuroimaging studies reported cerebral perfusion abnormalities in individuals with alcohol use disorders. However, no longitudinal magnetic resonance imaging (MRI) studies of cerebral perfusion changes during abstinence from alcohol have been reported. Methods:, Arterial spin labeling MRI was used to evaluate cortical gray matter perfusion changes in short-term abstinent alcohol dependent individuals in treatment and to assess the impact of chronic cigarette smoking on perfusion changes during abstinence. Seventy-six patients were scanned at least once. Data from 19 non-smoking (17 males, 2 females) and 22 smoking (21 males, 1 female) patients scanned at 1 and 5 weeks of abstinence were used to assess perfusion changes over time. Twenty-eight age-equated healthy controls (25 males, 3 females) were scanned for cross-sectional comparison, 13 of them were scanned twice. Given the age range of the cohort (28 to 68 years), age was used as a covariate in the analyses. Mean perfusion was measured in voxels of at least 80% gray matter in the frontal and parietal lobes and related to neurocognitive and substance use measures. Results:, At 1 week of abstinence, frontal and parietal gray matter perfusion in smoking alcoholics was not significantly different from that in non-smoking alcoholics, but each group's perfusion values were significantly lower than in controls. After 5 weeks of abstinence, perfusion of frontal and parietal gray matter in non-smoking alcoholics was significantly higher than that at baseline. However, in smoking alcoholics, perfusion was not significantly different between the time-points in either region. The total number of cigarettes smoked per day was negatively correlated with frontal gray matter perfusion measured at 5 weeks of abstinence. Lobar perfusion measures did not correlate significantly with drinking severity or cognitive domain measures at either time-point. Conclusion:, Although cerebral perfusion in alcohol dependent individuals shows improvement with abstinence from alcohol, cigarette smoking appears to hinder perfusion improvement. [source]

    The Impact of Depressive Symptoms on Alcohol and Cigarette Consumption Following Treatment for Alcohol and Nicotine Dependence

    ALCOHOLISM, Issue 1 2008
    Molly M. Kodl
    Background:, Although depression is common among alcohol and tobacco dependent patients, its impact on treatment outcomes is not well established. The purpose of this study was to examine the impact of depressive symptoms on abstinence from tobacco and alcohol after treatment for alcohol dependence and nicotine dependence. Methods:, The Timing of Alcohol and Smoking Cessation Study (TASC) randomized adults receiving intensive alcohol dependence treatment, who were also smokers, to concurrent or delayed smoking cessation treatment. The sample consisted of 462 adults who completed depression and substance use (alcohol and smoking) assessments at treatment entry and 6, 12, and 18 months posttreatment. Longitudinal regression models were used to examine the relationships between depression and subsequent abstinence from alcohol and tobacco after baseline characteristics, including alcohol and smoking histories, were considered. Results:, Depressive symptoms were prospectively related to nonabstinence from alcohol. Depressive symptoms at the previous assessment increased the odds of drinking at the subsequent time point by a factor of 1.67 (95% CI 1.14, 2.43), p < 0.01. Depressive symptoms were not significantly related to subsequent abstinence from cigarettes. Conclusions:, Depression is an important negative predictor of the ability to maintain abstinence from alcohol within the context of intensive alcoholism and smoking treatment. It may be important to include depression-specific interventions for alcohol and tobacco dependent individuals to facilitate successful drinking treatment outcomes. [source]

    fMRI BOLD Response to the Eyes Task in Offspring From Multiplex Alcohol Dependence Families

    ALCOHOLISM, Issue 12 2007
    Shirley Y. Hill
    Background:, Increased susceptibility for developing alcohol dependence (AD) may be related to structural and functional differences in brain circuits that influence social cognition and more specifically, theory of mind (ToM). Alcohol dependent individuals have a greater likelihood of having deficits in social skills and greater social alienation. These characteristics may be related to inherited differences in the neuroanatomical network that comprises the social brain. Methods:, Adolescent/young adult participants from multiplex AD families and controls (n = 16) were matched for gender, age, IQ, education, and handedness and administered the Eyes Task of Baron-Cohen during functional magnetic resonance imaging (fMRI). Results:, High-risk (HR) subjects showed significantly diminished blood oxygen level dependent (BOLD) response in comparison with low-risk control young adults in the right middle temporal gyrus (RMTG) and the left inferior frontal gyrus (LIFG), areas that have previously been implicated in ToM tasks. Conclusions:, Offspring from multiplex families for AD may manifest one aspect of their genetic susceptibility by having a diminished BOLD response in brain regions associated with performance of ToM tasks. These results suggest that those at risk for developing AD may have reduced ability to empathize with others' state of mind, possibly resulting in diminished social skill. [source]

    Both Global Gray Matter Volume and Regional Gray Matter Volume Negatively Correlate with Lifetime Alcohol Intake in Non,Alcohol-Dependent Japanese Men: A Volumetric Analysis and a Voxel-Based Morphometry

    Background: Non,alcohol-dependent heavy drinkers, as well as alcohol-dependent individuals, show brain atrophy. The purpose of this study was to evaluate whether there are correlations between global and regional gray matter volumes and the lifetime alcohol intake using volumetric analysis and voxel-based morphometry (VBM) among Japanese non-alcohol,dependent male individuals. Methods: High-resolution three-dimensional magnetic resonance images were acquired from 405 Japanese non-alcohol,dependent male individuals. The collected images were normalized, segmented for volumetric analysis, and additionally smoothed for VBM. For volumetric analysis, the partial correlation coefficient was estimated between the gray matter ratio, which represents the percentage of gray matter volume in the intracranial volume, and the lifetime alcohol intake adjusted for the age of each subject. Multiple regression analysis was performed among regional gray matter volume, lifetime alcohol intake, and age using VBM. Results: Volumetric analysis revealed that gray matter ratio showed a negative correlation with the lifetime alcohol intake adjusted for age (p=0.059, partial correlation coefficient=,0.091). The VBM revealed that the gray matter volumes of the bilateral middle frontal gyri showed a significant negative correlation with the lifetime alcohol intake adjusted for age and systolic blood pressure (left side, p=0.006, Z=4.77; right side, p=0.023, Z=4.45, and p=0.046, Z=4.27). Conclusions: Our study suggests that non-alcohol,dependent Japanese male individuals show that both global gray matter volume and regional gray matter volume have negative correlations with the lifetime alcohol intake. Our study may contribute to clarifying the mechanism underlying the brain structural changes because of alcohol influence in healthy non-alcohol,dependent individuals. [source]

    Pain and Substance-Related Pain-Reduction Behaviors among Opioid Dependent Individuals Seeking Methadone Maintenance Treatment

    THE AMERICAN JOURNAL ON ADDICTIONS, Issue 2 2009
    Declan T. Barry PhD
    We surveyed 293 opioid dependent individuals seeking methadone maintenance treatment about their pain experiences and their substance-related pain reduction behaviors. Among the 213 respondents reporting recent pain of at least moderate typical pain intensity, two-thirds had a lifetime history of chronic pain. In comparison to those without a lifetime history of chronic pain, those with a lifetime history were older, reported higher pain frequency, were more likely to endorse accident or surgery and less likely to endorse "don't know" as the genesis of their recent pain, and endorsed comparable levels of substance-related pain reduction behaviors. These findings may have implications for resource and program planning in MMT programs. [source]

    Treatment of Cannabis Use Disorders: A Review of the Literature

    THE AMERICAN JOURNAL ON ADDICTIONS, Issue 5 2007
    Benjamin R. Nordstrom MD
    Cannabis is the most widely used illicit drug in the United States. Despite the fact that there are large numbers of people with cannabis dependence, relatively little attention has been paid to the treatment of this condition. This article seeks to critically review the existing literature about the various psychosocial and pharmacologic treatments of cannabis dependence. We begin with a discussion of the early treatment literature which draws primarily from anecdotal experience and open, uncontrolled trials and proceed through two recent, large, randomized controlled trials of psychotherapies for the treatment of cannabis dependence. We conclude that while a number of psychotherapies have been found to be effective in treating this disorder, with the exception of adding vouchers to reinforce negative urine toxicology screens, no form of psychotherapy has been found to be more effective than any other. In addition, we review the only two clinical pharmacotherapy trials for cannabis dependence as well as the pre-clinical laboratory pharmacotherapy trials in cannabis dependent individuals. We also review pertinent dual-diagnosis pharmacotherapy trials and discuss potential future directions in treatment research for the pharmacotherapy of cannabis dependence. [source]
