The Effect of NK1R Antagonism on Alcohol Craving and PTSD Symptoms in Alcohol Dependent Patients...
AlcoholismAlcohol Dependence1 moreObjective: Alcoholism is highly co-morbid with post traumatic stress disorder (PTSD). Since stress and negative affective states are major relapse triggering factors for alcohol use, the negative symptoms associated with PTSD are thought to promote alcohol dependence. Substance P, which is released in the amygdala in response to stress, acts at NK1 receptors (NK1Rs) to mediate behavioral stress responses. Blockade of the NK1R represents a novel approach for anti-stress actions. In a recent double blind, placebo controlled study involving detoxified anxious alcoholics, we found that NK1R antagonism decreased alcohol cravings, attenuated cortisol response to stress, and significantly decreased insula activation in response to negative sensory input. The present study is intended to expand the findings and determine whether the NK1R is a candidate target for treating alcohol dependent patients with PTSD. Study Population: On hundred twenty participants with PTSD and co-morbid alcohol dependence will be recruited and stratified by PTSD etiology (60 participants each with civilian and combat PTSD, resp). Within each stratum, the treatment groups will be balanced for sex using urn randomization. Stratification is indicated since civilian and combat-related PTSD can theoretically have a different pathophysiology. Civilians typically experience a single trauma exposure of invariably high magnitude, resulting in symptoms immediately. Combat-related PTSD typically results from multiple traumatic exposures over a prolonged period of time, of variable magnitude, and frequently with delayed emergence of symptoms. Design: Participants will be admitted to the National Institute on Alcohol Abuse and Alcoholism (NIAAA) research inpatient unit at the NIH Clinical Research Center (CRC) under protocol number 05-AA-0121 for assessment and treatment of people with alcohol drinking problems, which provides diagnostic assessments and standard withdrawal treatment if needed. Participants will enter into the present protocol once such treatment, if needed is completed. Following inclusion, all participants will receive 1 week of single blind placebo, and will then be randomized to double blind treatment with aprepitant or placebo. Randomized treatment will be for 3 weeks. Spontaneous cravings for alcohol, and ratings of psychopathology will be obtained twice weekly on the inpatient unit throughout the study. Cravings as well as endocrine and immune responses will also be assessed in a challenge session that combines a social stressor and exposure to physical alcohol cues. During the final week, three sessions utilizing scripts will be carried out, on separate days in counter-balanced order, exposing the participant to personalized trauma, alcohol-associated or neutral stimuli. Cravings as well as endocrine and immune responses will also be assessed during the script presentations. A functional magnetic resonance imaging (fMRI) session will be carried out last to assess responses to affective stimuli. Participants will remain hospitalized throughout the study, and will remain on the unit for a three day post-medication monitoring period. Outcome Measures: The primary outcome will be craving alcohol and changes in PTSD symptoms resulting from the script sessions. Secondary outcomes will include cravings and changes in PTSD symptoms resulting from the combined social stress-alcohol cure challenge session, spontaneous craving and PTSD symptoms during hospitalization, and brain responses on the fMRI session. Changes in PTSD symptoms and cravings for alcohol are intended to be surrogate markers for the overall effect of the drug treatment and are not intended to represent global improvement for either PTSD or alcoholism.
Neuromodulation of Trauma Memories in PTSD & Alcohol Dependence
Alcohol DependencePTSDThe purpose of this study is to examine the effect of propranolol versus placebo on craving, distress and cue reactivity to trauma and alcohol cues.
The Effects of Levetiracetam on Alcohol Dependent Subjects
AlcoholismThis study will attempt to examine whether Levetiracetam (Keppra (TM)) can help people with alcohol dependence cut down on their alcohol consumption. In addition, the investigation will assess the effectiveness of Keppra on reducing withdrawal symptoms post alcohol cessation. Matched group of historical controls of alcohol dependent patients receiving placebo will be used for comparison.Based on the mechanism of action of Keppra we hypothesize that it may be effective in promoting abstinence and reducing drinking behavior in alcohol dependent patients.
Reinforcement of Abstinence and Continuing Care in Substance Abuse Treatment
Substance Use DisordersAlcohol Abuse3 moreThe Contracts, Prompts, and Social Reinforcement (CPR) intervention was designed to address the continuing care adherence needs of veterans presenting for substance use disorder (SUD) treatment. Final results of our recently completed HSR&D clinical trial suggest CPR meaningfully impacts aftercare adherence and abstinence rates. However, CPR did not impact abstinence rates at earlier follow-up points, other important measures of treatment outcome, or AA/NA support group attendance. Furthermore, the generalizability of CPR to other sites has not been established. Thus, the intervention has been modified and pilot testing of this improved version of CPR, which includes contingent reinforcement of abstinence and improved prompting of AA/NA attendance (CPR+), shows promising results. We are conducting a multi-site randomized clinical trial to examine the effectiveness of CPR+. We recruited 183 veterans seeking residential treatment at the Salem and Jackson VAMCs. Our primary hypothesis is that the CPR group will have higher 1-year abstinence rates compared to the STX group. Our secondary hypotheses are that the CPR will be particularly effective for individuals with co-morbid psychiatric disorders, and that the CPR+ group will remain in AA/NA and in aftercare for a longer duration, have fewer days of substance use, fewer hospitalizations, and lower costs of care. Treatment outcome will be measured 3-, 6-, and 12-months after participants enter treatment and compared to baseline levels. The current study will seek to extend past findings to show longer-term effectiveness of the CPR+ intervention on continuing care adherence and greater impact on treatment outcome. Dissemination and implementation efforts will be ongoing for this brief, inexpensive intervention, which offers an important means to improve participation and outcome for individuals seeking SUD treatment within the VAMC. Data collection and analysis has been completed.
An Internet-based Intervention for Problem Drinking
AlcoholismThe main aim of this randomized controlled trial is to evaluate the efficacy of an Internet-delivered self-help intervention for problem drinkers in the general population. Adult problem drinkers with home access to the Internet will be recruited from the CAMH Monitor. Subjects will be randomly assigned to receive a website address where they can obtain personalized feedback about their drinking, or to a no intervention control group. Three-month and six-month follow-up surveys will be conducted by mail to assess drinking over the following three month periods. Collaterals will be requested and interviewed after the six-month follow-up. Subjects will be paid $40.00 and collaterals will be paid $20.00 for their participation. Drinking at three- and six-months will be compared between the groups. Subjects in the control group will be provided with the website address following the six-month follow-up.
Acamprosate Initiated During Alcohol Detoxification
Alcohol Use DisorderAcamprosate is approved by the Food and Drug Administration (FDA) for the treatment of alcoholism. The purpose of this study is to see if initiating acamprosate early in alcohol detoxification instead of waiting until detoxification has been completed effects the course of detoxification, adverse events during detoxification, drop out rate during the rehabilitative treatment phase, or overall efficacy of acamprosate for those with alcohol dependence who plan to receive at least two months of rehabilitative pharmacotherapy with acamprosate.

Treatment of Patients With Alcoholism and Attention Deficit Disorder
AlcoholismAttention Deficit DisorderThis study of persons with both alcoholism and ADHD will determine whether adding the drug methylphenidate to a standard treatment program will decrease alcohol use. In approximately half of patients with ADHD, symptoms persist into adulthood, and the untreated condition is associated with a significantly increased incidence of substance use disorder. Also, more than one-third of adults with substance use disorder have symptoms of ADHD. This study will evaluate the effectiveness of adding methylphenidate to a standard alcohol treatment program in improving patients' treatment compliance and decreasing adverse consequences of drinking, as well as monitoring their attention deficit/hyperactivity symptoms, People 21 to 65 years of age with alcoholism and attention deficit hyperactivity disorder (ADHD) may be eligible for this study. Participants are randomly assigned to receive either slow-release methylphenidate (an approved medication for ADHD) or placebo. All subjects participate in NIAAA's alcohol treatment program, which includes a standardized 12-week behavioral therapy course and treatment with naltrexone, a medication to prevent relapse. Patients are assessed once a week with the standard NIAAA treatment evaluation battery, including: Timeline Followback: A validated self-report method to assess a person's drinking over a defined interval in time Addiction Severity Index: A validated interview that measures problem severity in seven areas related to drug and alcohol abuse Biomarkers for alcohol abuse Conners Adult ADHD Rating Scale (a rating scale for ADHD symptoms and severity)
Placebo Controlled Trial of Depakote ER in Alcohol Dependent Patients With Mood and/or Anxiety Symptoms...
AlcoholismAlcohol Related Disorders1 moreThe purpose of this study is to test the safety and effectiveness of an extended release form of a medication called divalproex sodium (Depakote ER) for the treatment of people with alcohol dependence who have mood and/or anxiety symptoms. This medication has helped reduce symptoms of acute alcohol withdrawal as well as stabilize mood symptoms in bipolar disorder and other mental health disorders. This study will test the hypothesis that divalproex sodium will help reduce mood and anxiety symptoms during early abstinence from alcohol and in turn reduce relapse and craving for alcohol.
Health Behavior Feedback Study for Veterans With Hepatitis C
AlcoholismAlcohol Abuse2 moreThe purpose of this study was to explore whether a brief (3 session) intervention would impact health behavior of veterans with hepatitis C. The main focus of the intervention was on reduction of heavy drinking with patients who have liver disease. Other study goals were to increase the likelihood that patients would seek out substance use treatment and/or hepatitis C health care services. The study also tested the use of a liver function test called CDT/GGT in detecting heavy drinking. The main hypothesis was that a 3 session intervention with personalized feedback about health behavior would result in a reduction in alcohol use and increased use of substance use treatment and hepatology health care.
