Environment and Alcohol: A Pilot Study

Background: Alcohol use disorder (AUD) is a chronic disease that causes more than 140,000 US deaths each year. AUD treatment often includes therapy and medication. Some people with AUD may also benefit from behavioral and lifestyle changes. Objective: To evaluate the effects of different activities and environments on drinking behaviors and mental health in people with AUD. Eligibility: People aged 21 years and older with AUD. Design: Participants will have up to 10 study visits in Baltimore. Participants will have a baseline visit. They will have a physical exam with blood and urine tests. They will have a breath test for alcohol and a test that measures body composition. They will answer questions about their alcohol and substance use; mental and physical health; mood and anxiety; and sleep quality. Participants will download an app called MetricWire. The app will send 3 sets of questions to be answered at different times throughout the day. The study visits will include 2 stages: 1. Active stage. On these visits, participants will use a virtual reality system called the Meta Quest Pro (MQP) as they choose. Then they may choose among video games, puzzles, books, crafts, and other activities.. These sessions will last for 3 hours. 2. Passive stage. On these visits, participants will watch videos selected by the research team. These sessions will last for 3 hours. On the last visit of each stage, participants will sit in a room that looks like a bar. They will answer questions about their cravings, their urge to drink, and how many drinks they would buy. Participants will be served 1 drink containing alcohol. They will be asked about their cravings and subjective effects of alcohol after drinking it.

The Impact of Heavy Alcohol Use on Saliva and Oral Health

Background: People with alcohol use disorder (AUD) have a higher rate of dental and gum disease. Poor oral health can increase the risk of other diseases, such as diabetes and stroke. Researchers want to learn more about how to identify developing inflammation in the mouth. They also want to know how improved oral health education and behaviors can affect inflammation in people with AUD. Objective: This study has 2 goals: (1) to test the usefulness of a new questionnaire about oral health and (2) to learn more about how oral health behaviors affect inflammation in people with AUD. Eligibility: People aged 18 years and older who are staying on an inpatient unit being treated for AUD. Healthy volunteers are also needed. Design: The study is divided into 2 parts: People will participate in either one part or the other. In part 1, participants will have 1 visit. They will have a physical exam. They will answer 18 questions for a survey about how they care for their teeth. In part 2, participants with AUD will have a physical exam. They will provide saliva and blood samples. They will have a dental exam with X-rays. They will fill out questionnaires about their health, mental health, social habits, diet, and sleep. They will keep a diary of their nicotine use for 4 weeks while inpatient. Healthy volunteers will have 1 visit. They will have a physical exam and provide blood and saliva samples. They will have a dental exam with X-rays. They will fill out questionnaires.

GLP-1 RA on Alcohol Consumption, Metabolism and Liver Parameters in Patients With Obesity and Fatty Liver Disease

There is evidence that alcoholic beverage consumption significantly interacts with food energy intake. Furthermore, there is accumulating evidence showing independent, combined, and modifying effects of alcohol and metabolic factors on the onset and progression of chronic liver disease. Preclinical and clinical data have showed that GLP-1 RA can decrease alcohol consumption, particularly in obese patients. Moreover there is evidence that semaglutide can improve the liver sinusoidal milieu in pre-clinical models of cirrhosis. In this study, the investigators aim to assess if patients treated with semaglutide and receiving counselling will achieve a significantly higher alcohol abstinence compared to patients only receiving counselling.

AAT for Alcohol Use Disorder in Veterans

The proposed study will test a novel treatment for alcohol use disorders (AUD) to determine if it helps Veterans reduce their hazardous drinking and recover from alcohol-related functional impairments across social, occupational, and domestic domains. To do so, the investigators will evaluate clinical, cognitive, and neural effects of a computer-delivered Approach Avoidance Training (AAT) treatment - which changes implicit tendencies to approach alcohol-related cues - in conjunction with standard VA care. The project will support RR\&D's mission to improve Veterans' participation in their lives and community by determining if this innovative alternative technique can improve recovery outcomes for Veterans with AUD and exploring how the intervention works.

PET Imaging of Phosphodiesterase-4B (PDE4B) in Alcohol Use Disorder

Background: People with alcohol use disorder (AUD) also often have bouts of depression called major depressive episodes (MDEs). People having MDEs have been found to have low levels of a protein called PDE4B in the brain. Researchers want to find out if people with AUD also have low levels of PDE4B. This research may help lead to better treatments for AUD. Objective: To find out (1) if PDE4B levels are lower in people who are withdrawing from AUD and (2) if their PDE4B levels go up after they abstain from alcohol for 3 to 4 weeks. Eligibility: Adults aged 18 to 70 years with AUD. They must be enrolled in protocol 14-AA-0181. Design: Participants enrolled in protocol 14-AA-0181 will stay in the clinic for 3 to 4 weeks for alcohol withdrawal. During this stay, they will have some added procedures for the current study. Within the first week, participants will have a positron emission tomography (PET) scan of the brain. A needle will be used to guide a thin plastic tube (catheter) into a vein in one arm. An experimental substance called a radioactive tracer will be injected through the catheter. This tracer binds to PDE4B and makes it easier to see the protein in the brain. For the scan, participants will lie on a table that slides into a doughnut-shaped machine. Participants will have a second PET scan toward the end of their stay in the clinic. Participants may also have a magnetic resonance imaging (MRI) scan of the brain. They will lie on a bed that slides into a tube....

Acute Effects of Alcohol on PET Imaging of Phosphodiesterase-4B (PDE4B)

Background: Phosphodiesterase-4B (PDE4B) is a protein in the brain that may play a role in several mental health disorders. Researchers want to know if drinking alcohol increases the binding of a radioactive tracer to PDE4B in the brain because of increased activity and/or amount of the protein. This knowledge may help create new ways to treat people with alcohol use disorder (AUD). Objective: To learn if alcohol increases PDE4B activity in the brain. Eligibility: Healthy people aged 21 to 70 years who drink socially but do not have AUD. They must be enrolled in protocol 14-AA-0181"NIAAA Natural History Protocol". Design: Participants will have up to 4 clinic visits with up to 3 imaging scans of the brain; these will include 1 or 2 positron emission tomography (PET) scans and 1 magnetic resonance imaging (MRI) scan. The first PET scan will be a baseline. Participants will receive a radioactive tracer through a tube inserted into a vein. A second tube will be inserted so that blood can be drawn during the scan. Participants will lie on a bed that slides into a doughnut-shaped machine. This visit will take about 6 hours. For the next PET scan, participants will receive alcohol (ethanol) through a tube in a vein until they have a blood alcohol concentration that is equal to the legal driving limit. This is the same as 4 or 5 drinks for most people. After the scan, participants must remain at the clinic for a few hours until their blood alcohol drops. This visit will take 14 to 16 hours. The MRI scan of the brain will take up to 2 hours in a separate clinic visit.

Cessation or Reduction of Alcohol Consumption in Veterans: A Randomized Controlled Trial for Alcohol Use Disorder (CRAVE)

This clinical trial aims to test the effectiveness and safety of semaglutide, a GLP-1 receptor agonist, in treating moderate to severe alcohol use disorder (AUD) in Veterans. Participants who qualify will be randomly assigned to receive either semaglutide injections or placebo injections over a 24-week period, followed by a 4-week post-treatment safety assessment period. Participants receiving semaglutide will start with a low dose, gradually increasing to a maximum of 2.4 milligrams (mg) per week, depending on their tolerance. The primary measure of success will be a reduction in risky drinking, assessed through a reliable calendar-based interview method called the Timeline Follow-Back (TLFB), a well-validated calendar-based interview technique for recording daily alcohol consumption. The purpose of this research is to gather information on the safety and effectiveness of semaglutide for treating AUD, potentially offering a new and more appealing treatment option.

Tirzepatide in MetALD

Background: People with alcohol use disorder (AUD) often develop metabolic alcohol-associated liver disease (MetALD). MetALD is a term for the heart, liver, obesity, and other issues that can accompany AUD. MetALD can be fatal. An approved weight management drug (Tirzepatide) may be able to help people with AUD and MetALD control their alcohol intake. Objective: To test Tirzepatide in people with AUD and MetALD. Eligibility: People aged 21 years and older with AUD and MetALD. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have a test of their heart function. They will have a Fibroscan: This test uses ultrasound to measure how stiff the liver is. They will answer questions about their alcohol drinking, eating habits, and mental health. Participants may opt to have imaging scans of their brain and liver. These tests will be repeated in a baseline visit. This visit will take up to 6 hours. Tirzepatide is injected under the skin once a week for 12 weeks. Participants will visit the clinic to receive each injection. Some participants will get a placebo. A placebo is given just like a Tirzepatide injection but contains no medicine. The physical exam and other tests will be repeated during clinic visits. The Fibroscan will be repeated every 2 weeks during the study. Each weekly visit will take up to 3 hours. All tests will be repeated on the last visit. These tests will include the imaging scans and Fibroscan. Participants will learn about treatment options for AUD; they will be given recommendations on ways to reduce alcohol intake. This visit will take up to 6 hours.

Self-Concept and Autobiographical Memory in Alcohol Use Disorder

This study has two objectives. First, to evaluate the effectiveness of psychotherapy sessions based on self-concept and autobiographical memory in patients suffering from alcohol use disorders (AUD). Second, investigate the relationship between drinking identity and AUD. These objectives will be investigated according to a longitudinal design. In this study, the drinking identity is evaluated on its implicit dimension and on its explicit dimension. Levels of alcohol use and dependence are assessed by the amount and frequency of drinking, the duration of abstinence, and the intensity of AUD symptoms. These assessments consist three visits: on the day of inclusion, then at three months and six months after the first visit. The psychotherapy sessions consist of four individual sessions. They are inspired by the Social Identity Mapping in Addiction Recovery (SIM-AR) by Beckwith et al. (2019), combined with autobiographical reasoning exercises. Patients with an AUD, participants in the study, are recruited from the addiction department of the Etablissement Public de Santé Mentale de la Marne. To investigate the effects of individual psychotherapy sessions, two groups of patients are constituted randomly. The first group will have four psychotherapy sessions between the first visit and the second vist. The second group will not follow psychotherapy sessions but will benefit from the usual addiction treatments. The first hypothesis is that patients who have completed the psychotherapy sessions will have lower alcohol consumption (frequency, quantities, peaks) and symptoms of AUD (cravings, drinking refusal self-efficacy and feeling of recovery) than those who have not benefited from the program. The second hypothesis is that implicit and explicit levels of drinking identity will predict alcohol consumption (frequencies, quantities, peaks) and symptoms of dependence (cravings, drinking refusal self-efficacy and feeling of recovery) for all participants.

Effects of Ketogenic Diet on Alcohol Intoxication

The research study is being conducted to better understand the effects of ketosis on brain functioning and the acute effects of alcohol. Participants will be asked to undergo \~4 weeks of ketogenic diet intervention. The study involves three lab visits: Lab 1 before starting the diet, Lab 2 after about 2 weeks after starting the diet, and Lab 3 after being on the diet for 4 weeks. All of the labs will include an alcohol tolerance test, and blood draws. Lab 1 and Lab 3 will also include an Magnetic resonance imaging scan. Due to scheduling, study procedures at 2 and 4 weeks may occur +/- 3 days. Magnetic resonance imaging (MRI) of the brain will measure levels of nicotinamide adenine dinucleotide (NAD) (a coenzyme that is important for energy metabolism), lactate (a metabolite produced during energy metabolism), and neurotransmitters glutamate and GABA. Alcohol tolerance will be tested using a dose of alcohol (approximately 4-5 alcohol beverages) to will elevate breath alcohol levels to approximately 0.08% to measure the acute effects of alcohol. Blood samples will be collected to measure varying metabolites.

Spironolactone in Alcohol Use Disorder (SAUD)

Background: Alcohol use disorder (AUD) affects about 29.5 million people in the United States. Only 3 medicines have been approved by Food and Drug Administration to treat AUD. Researchers want to find better treatments for AUD. Animal studies found that a medicine called spironolactone, may decrease the amount of alcohol the animals drank. Spironolactone is approved to treat high blood pressure, or heart failure in people. It is not approved to treat AUD. Objective: To test a medicine (spironolactone) in people who sometimes drink excessive alcohol in order to understand how the body breaks down spironolactone and if there are any side effects in people who drink alcohol while taking this medicine. Eligibility: People aged 21 and older with AUD. Design: Participants will have 4 separate 7-day stays at a clinic in Baltimore over 2 months. Spironolactone is a capsule you swallow. Participants will take a capsule twice a day for 5 days during each clinic stay. During 1 of their 4 stays, they will take a placebo instead of the medicine. The placebo capsule looks just like the spironolactone capsule but contains no medicine. Participants will not know when they are taking the medicine or the placebo. Participants will not drink alcohol until day 6 of each clinic stay. Then they will be asked to drink alcohol in a bar-like area in the clinic. Their breath and blood alcohol levels and their well-being will be measured. Participants will undergo other tests in the clinic: A DEXA (dual energy X-ray absorptiometry) scan uses X-rays to measure bone density and muscle mass. Participants will lie on an open-top, padded table, then a small arm will scan the full length of their body. The radiation participants will get in this study is about the same as from one regular x-ray. Blood tests. Participants may feel some discomfort at the site of needle entry. Electrocardiogram. This test records the heart activity. Sensors are attached to the skin with stickers and removed after a few minutes. Urine tests. All urine will be collected over a 3-day period during each stay. We will measure the amount of urine, and different hormones and salts in the urine. Questionnaires and tasks. Participants will answer questions about their alcohol use. They will perform tasks to test mood, craving, mental and physical coordination, and how much they feel an effect from alcohol after drinking.

Optimizing Treatment of Co-occurring Smoking and Unhealthy Alcohol Use Among PWH in Nairobi, Kenya

People with HIV (PWH) smoke tobacco cigarettes and drink alcohol at higher rates than the general population, both in the US and internationally, including low- and middle-income countries. Now that effective antiretroviral therapy is available throughout most of the world, PWH are surviving long enough to manifest the lethal consequences of both their smoking and drinking. In this project, the investigational team aims to advance the knowledge and understanding of treatment strategies (i.e. individual intensive counseling ± pharmacotherapy with cytisine) that target both tobacco and alcohol use among PWH in Kenya, a resource constrained environment, and to generate outcome data that may benefit co-users of tobacco and alcohol throughout the world.

Pomegranate Dietary Supplements in AUD and ALD

The goal of this project is to determine an individual's ability to generate active gut microbial metabolites called urolithins upon consumption of pomegranate dietary supplements. Recent publications have reported that urolithins are the major active metabolites responsible for the beneficial effects of eating pomegranates, berries, or walnuts. However, the production of urolithins from the parent compound ellagic acid (EA) is dependent upon the presence of certain bacteria in the human gut. In this trial, we propose to investigate variations in gut microbiota and their capacity to metabolize pomegranate dietary supplements (PDS) into active urolithins. We will measure the levels of urolithins in blood as well as inflammatory cytokines in plasma samples upon consumption of PDS.

Temporally-Resolved Electrophysiology of Acamprosate Treatment of Alcohol Use Disorder

Background: Chronic heavy drinking can cause alcohol use disorder (AUD). AUD changes how the brain works. People with AUD may drink compulsively or feel like they cannot control their alcohol use. Acamprosate is an FDA-approved drug that reduces anxiety and craving in some, but not all, people with AUD. Objective: To learn more about how acamprosate affects brain function in people with AUD. Eligibility: People aged 21 to 65 years with moderate to severe AUD. Design: Participants will stay in the clinic for 21 days after a detoxification period of approximately 7 days. Acamprosate is a capsule taken by mouth. Half of participants will take this drug 3 times a day with meals. The other half will take a placebo. The placebo looks like the study drug but does not contain any medicine. Participants will not know which capsules they are taking. Participants will have a procedure called electroencephalography (EEG): A gel will be applied to certain locations on their scalp, and a snug cap will be placed on their head. The cap has sensors with wires. The sensors detect electrical activity in the brain. Participants will lie still and perform 2 tasks: they will look at different shapes and press a button when they see a specific one; and they will listen to tones and press dedicated buttons when they hear the corresponding tones. Participants will have 2 EEGs: 1 on day 2 and 1 on day 23 of their study participation. They may opt to have up to 4 more EEG studies (one on day 13 and one on each of the three follow-up visits) and 2 sleep studies, in which they would have sensors attached to their scalp while they sleep. Participants may have up to three follow-up visits for 6 months.
