Alcohol Drinking Clinical Trials

The research study is being conducted in health controls to better understand the effects of ketosis on brain functioning after 3 different, randomly assigned, 3-day dietary interventions and the acute effects of alcohol after consuming about 4-5 alcohol beverages. The labs visits will use magnetic resonance imaging (MRI) scans to study the brain, measuring levels of nicotinamide adenine dinucleotide (NAD), lactate, neurotransmitters glutamate, and Gamma-aminobutyric acid (GABA).

The purpose of this research is to study how a nutritional ketone ester may effect brain function and alcohol consumption in regular alcohol users. The study will see how the brain responds, once after drinking the ketone ester and once after drinking a "placebo", which will look and taste the same as the ketone ester drink. Metabolic ketosis induced by a ketogenic diet has been previously shown to elevate brain ketone bodies and reduce alcohol withdrawal symptoms in humans with AUD, and reduce alcohol consumption in alcohol-dependent rats. The study investigates whether metabolic ketosis induced by a one-dose nutritional ketone ester (KE) reduces brain reactivity to alcohol cues (fMRI), alcohol craving and alcohol consumption in humans with AUD, and if KE elevates ketone bodies using proton spectroscopy. This study uses a double blind, random ordered, 2-way crossover design in n=20 non-treatment seeking AUD who come in on two separate testing days: on one testing day the participants consume KE ((R)-3-hydroxybutyl (R)-3-hydroxybutyrate), and on another testing day a drink with isocaloric dextrose (DEXT), after which participants are scanned for 1H-MRS and fMRI and complete an alcohol consumption paradigm each day after scanning.

This is a single blinded, randomized trial to evaluate the immediate subjective and objective effects of alcohol after a dose ketone supplement compared to a placebo in 10 health volunteers. Subjects will complete 2 lab visits where they consume a dose of alcohol (based on weight), to bring their breath alcohol concentration to about 0.050%. Participants will randomly receive ketone supplement at one lab and the placebo at the next lab. Read Less

Background: - Scientists know that alcohol use disorders affect brain structure. They want to know more about the effects of alcohol use disorders on a person s behavior. They want to develop tasks that can be done inside a scanner that can help them better understand these effects in later studies. Objective: - To develop tasks that investigate a person s behavior that can be used in later studies. Eligibility: Inpatient participants of another study. They must be physically healthy right-handed adults 18-60 years old. Healthy right-handed volunteers 18-65 years old. Design: Participants will be screened with medical history and physical exam. They will have an EKG to record heart activity. They will give blood and urine samples and have a psychiatric interview. Participants will have between one and three visits. Participants will be asked about their alcohol drinking to see if they have an alcohol use disorder. Participants will complete one of three simple computerized tasks either inside the magnetic resonance imagining (MRI) scanner or outside of it. The MRI scanner takes pictures of the brain. The scanner is a metal cylinder. Participants lie on a table that can slide in and out of the cylinder. They will be in the scanner for about 60 minutes. They may have to lie still for up to 20 minutes. The scanner makes loud knocking noises, but they will get earplugs. Read Less

This study has two phases: Phase 1 is to examine blood pressure, microvascular function, and sympathetic nerve activity in mid-life adult binge drinkers vs. alcohol abstainers/moderate drinkers. Phase 2 is to examine the effect of 8-week aerobic exercise training on blood pressure, microvascular function, and sympathetic nerve activity in mid-life adult binge drinkers Read Less

Alcohol use disorders (AUDs) affect up to 60% of individuals with bipolar disorder during their lifetime and is associated with worse illness outcomes, yet few studies have been performed to clarify the causes of this comorbidity. Understanding biological risk factors that associate with and predict the development of AUDs in bipolar disorder could inform interventions and prevention efforts to reduce the rate of this comorbidity and improve outcomes of both disorders. Identifying predictors of risk requires longitudinal studies in bipolar disorder aimed at capturing the mechanisms leading to the emergence of AUDs. Previous work in AUDs suggest that subjective responses to alcohol and stress-related mechanisms may contribute to the development of AUDs. In bipolar disorder, altered developmental trajectory of critical ventral prefrontal networks that modulate mood and reward processing may alter responses to alcohol and stressors; consequently, the disruption in typical neurodevelopment may be an underlying factor for the high rates of comorbidity. No longitudinal data exist investigating if this developmental hypothesis is correct. To address this gap, the investigators will use a multimodal neuroimaging approach, modeling structural and functional neural trajectories of corticolimbic networks over young adulthood, incorporating alcohol administration procedures, clinical phenotyping, and investigating effects of acute stress exposure and early life stress. Research aims are to identify biological risk factors-i.e., changes in subjective response to alcohol and associated neural trajectories-that are associated with the development of alcohol misuse and symptoms of AUDs over a two-year longitudinal period in young adults with bipolar disorder and typical developing young adults. Longitudinal data will be collected on 160 young adults (50% with bipolar disorder, 50% female; aged 21-26). This study is a natural extension of the PI's K01 award. How acute exposure to stress and childhood maltreatment affects subjective response to alcohol and risk for prospective alcohol misuse and symptoms of AUDs will be investigated. The investigators will test our hypothesis that developmental differences in bipolar disorder versus typical developing individuals disrupt corticolimbic networks during young adulthood, increase sensitivity to stress, and lead to changes in subjective response to alcohol and placebo response increasing risk for developing AUDs.

Individuals with posttraumatic stress disorder (PTSD) have greater prevalence of alcohol use disorders (AUDs), with this comorbidity associated with worse illness outcomes, yet there remains limited mechanistic understanding of how PTSD confers risk for AUD. Understanding risk factors that associate with and predict the development of AUDs in PTSD could inform interventions and prevention efforts to reduce the rate of this comorbidity and improve outcomes of both disorders. Identifying predictors of risk requires longitudinal studies in PTSD aimed at capturing the mechanisms leading to the emergence of AUDs. There is growing evidence PTSD is related to biased decision-making during approach-avoidance conflict. Alcohol is also suggested to alter approach-avoidance decision-making. AUDs and acute alcohol intoxication is associated with a bias to seek out reward despite the possibility of threat (e.g., contributing to relapse following alcohol cue exposure and risky behavior during intoxication respectively). Alcohol-induced changes in approach-avoidance decision-making have not been investigated in the context of PTSD, but emerging data support the investigators' hypothesis that an interaction between alcohol and approach-avoidance conflict in PTSD may occur and contribute to risk for alcohol misuse and development of alcohol problems. No current data, cross-sectional or longitudinal, have tested the role of alcohol-induced changes in approach-avoidance conflict as a mechanism of risk for AUD among individuals with PTSD. To address this gap, the investigators propose to leverage the group's expertise in placebo-controlled alcohol administration procedures, longitudinal modeling, functional neuroimaging, and computational neuroscience approaches to investigate the effects of acute alcohol on approach-avoidance decision-making and mediating changes in multivariate neurocircuitry patterns in limbic, striatal, and salience networks.

Over one-quarter of American adults engage in hazardous drinking (i.e., a pattern of alcohol consumption that increases risk for harmful consequences), which is the third leading cause of preventable death in the U.S. Rates of hazardous drinking are significantly higher among individuals with (vs. without) chronic pain. Moreover, 20% of individuals prescribed opioids endorse concurrent alcohol and opioid use, which may interfere with chronic pain treatment and lead to dangerous/potentially fatal health effects. No interventions to date have targeted either hazardous drinking or concurrent use of alcohol and opioids in the context of chronic pain. The current four-year R01 builds upon our past work by developing a brief, single-session, computer-based, personalized feedback intervention (PFI) designed to enhance knowledge regarding adverse pain-alcohol-opioid interrelations, increase motivation and intention to reduce hazardous drinking, and reduce positive attitudes and intention regarding concurrent use of alcohol and prescription opioid medications. Specifically, we will develop an integrated PFI for hazardous drinkers with chronic pain who are prescribed opioids (PA-PFI). Our approach will follow a staged model consistent with NIH guidelines for developing and standardizing behavioral interventions. Phase IA activities will involve collecting qualitative and quantitative feedback from three iterative focus groups (N = 21) to refine intervention content and evaluate treatment acceptability and feasibility. Phase IB activities will include a proof-of-concept and highly rigorous randomized clinical trial designed to compare PA-PFI to control PFI (C-PFI) among a sample of 174 hazardous drinkers with chronic pain who are currently prescribed opioid medications. This study represents an important and pivotal step in the larger landscape of translating basic research to more efficacious strategies for reducing hazardous drinking among underserved populations with medical comorbidities. This intervention would be highly disseminable and relevant to millions of hazardous drinkers with chronic pain. Given the collective public health impact of chronic pain, hazardous drinking, and concurrent alcohol-prescription opioid use, we believe the current study will yield findings that enhance scientific knowledge, enhance our understanding of mechanisms in reciprocal pain-alcohol-opioid relations, and inform the development of novel treatments for hazardous drinkers with chronic pain that are adaptable and easily implemented across a variety of healthcare settings.

The purpose of this study is to evaluate the effects of two programs to prevent/reduce alcohol misuse among youth primary care patients. Depending on their study condition, youth will receive a brief web-based computer program or the web program + 8 weeks of supportive text messages. Parents/caregivers of youth are encouraged to use a freely available app to guide conversations with their child about drinking. This study will have significant impact by evaluating response to these scalable interventions which can be deployed widely in clinical care settings. Read Less
