The President released his FY 2019 budget, including an addendum, in February, requesting $33 billion for NIH, a $1 billion decrease from FY 2017, and $469.1 million for NIAAA, a $13.4 million decrease from FY 2017.

 

COLLABORATIVE RESEARCH ON ADDICTION AT NIH (CRAN) UPDATE  

Adolescent Brain and Cognitive Development (ABCD) Study

The ABCD Study (https://abcdstudy.org/) continues to meet enrollment targets and is now focusing on including subjects from population subgroups in sufficient numbers to allow the best opportunity for analyses. To date, more than 9,000 youth and their families have been recruited for the study, which is on target to meet the overall recruitment goal.

In late February 2018, in accordance with the commitment of NIAAA and the National Institute on Drug Abuse to make the ABCD Study data available to the widest possible number of researchers as soon as possible, the first curated data release was announced. Approximately 30 terabytes of data obtained from the first 4,500 participants were made available to scientists worldwide to conduct research on the many factors that influence brain, cognitive, social, and emotional development. This interim release provides high-quality baseline data on the sample of 9- to 10-year-old children, including basic participant demographics, assessments of physical and mental health, substance use, culture and environment, neurocognition, tabulated structural and functional neuroimaging data, and minimally processed brain images, as well as biological data such as pubertal hormone analyses. The data are made available through the National Institute of Mental Health (NIMH) Data Archive (https://data-archive.nimh.nih.gov/abcd) and can be accessed by researchers who obtain a free NIMH Data Archive account (https://data-archive.nimh.nih.gov/abcd/request-access). All personally identifiable information is removed from the data to ensure participant confidentiality and anonymity.

NIAAA RESEARCH HIGHLIGHTS

Digoxin Suppresses Pyruvate Kinase M2-Promoted HIF-1A Transactivation in Steatohepatitis

Significance: Hypoxia is a common feature observed in animal models of alcohol-induced liver disease and, more recently, in the liver of human binge drinkers. A highly conserved host-protective response to hypoxia is orchestrated by the transcription factor HIF-1 alpha. A persistent HIF-1 alpha response to hypoxia in a host, similar to chronic inflammation, is thought to contribute to the development of many medical conditions, including alcohol-associated liver diseases (AALD). The current study provides further evidence supporting this concept and also demonstrates the potential of digoxin, a widely used medication for heart disease, in treatment of AALD via the HIF-1 alpha pathway.

Sterile inflammation after tissue damage is a ubiquitous response, yet it has the highest amplitude in the liver. This has major clinical consequences, for alcoholic and non-alcoholic steatohepatitis (ASH and NASH) account for the majority of liver disease in industrialized countries and both lack therapy. Requirements for sustained sterile inflammation include increased oxidative stress and activation of the HIF-1α signaling pathway. We demonstrate the ability of digoxin, a cardiac glycoside, to protect from liver inflammation and damage in ASH and NASH. Digoxin was effective in maintaining cellular redox homeostasis and suppressing HIF-1α pathway activation. A proteomic screen revealed that digoxin binds pyruvate kinase M2 (PKM2), and independently of PKM2 kinase activity results in chromatin remodeling and downregulation of HIF-1α transactivation. These data identify PKM2 as a mediator and therapeutic target for regulating liver sterile inflammation, and demonstrate a novel role for digoxin that can effectively protect the liver from ASH and NASH.

Apoptosis of Enterocytes and Nitration of Junctional Complex Proteins Promote Alcohol-Induced Gut Leakiness and Liver Injury

Significance: The molecular mechanisms through which binge alcohol-induced gut leakiness contributes to endotoxemia and inflammatory liver disease are poorly understood. This study demonstrated the critical roles that apoptosis of enterocytes (cells of the intestinal lining) and nitration of intestinal junctional complex proteins followed by ubiquitin-dependent proteolytic degradation play in promoting binge alcohol-induced gut leakiness.

Binge alcohol causes gut leakiness, contributing to increased endotoxemia and inflammatory liver injury, although the molecular mechanisms are still elusive. This study was aimed at investigating the roles of apoptosis of enterocytes and nitration followed by degradation of intestinal tight junction (TJ) and adherent junction (AJ) proteins in binge alcohol-induced gut leakiness. The levels of intestinal (ileum) junctional complex proteins, oxidative stress markers and apoptosis-related proteins in rodents, T84 colonic cells and autopsied human ileums were determined by immunoblot, immunoprecipitation, immunofluorescence, and mass-spectral analyses. Binge alcohol exposure caused apoptosis of gut enterocytes with elevated serum endotoxin and liver injury. The levels of intestinal CYP2E1, iNOS, nitrated proteins and apoptosis-related marker proteins were significantly elevated in binge alcohol-exposed rodents. Differential, quantitative mass-spectral analyses of the TJ-enriched fractions of intestinal epithelial layers revealed that several TJ, AJ and desmosome proteins were decreased in binge alcohol-exposed rats compared to controls. Consistently, the levels of TJ proteins (claudin-1, claudin-4, occludin and ZO-1), AJ proteins (β-catenin and E-cadherin) and desmosome plakoglobin were very low in binge-alcohol exposed rats, wild-type mice, and autopsied human ileums but not in Cyp2e1-null mice. Additionally, pretreatment with specific inhibitors of CYP2E1 and iNOS prevented disorganization and/or degradation of TJ proteins in alcohol-exposed T84 colonic cells. Furthermore, immunoprecipitation followed by immunoblot confirmed that intestinal TJ and AJ proteins were nitrated and degraded via ubiquitin-dependent proteolysis, resulting in their decreased levels. These results demonstrated for the first time the critical roles of CYP2E1, apoptosis of enterocytes and nitration followed by ubiquitin-dependent proteolytic degradation of the junctional complex proteins in promoting binge alcohol-induced gut leakiness and endotoxemia, contributing to inflammatory liver disease.

Implications of Altered Maternal Cytokine Concentrations on Infant Outcomes in Children with Prenatal Alcohol Exposure

Significance: This study represents the efforts of the Collaborative Initiative on Fetal Alcohol Spectrum Disorders (CIFASD), an interdisciplinary consortium of investigators supported by NIAAA. Using a sample of children enrolled in a prospective CIFASD cohort in Ukraine, the researchers examined the relationship between maternal alcohol consumption, maternal immune profile, and risk of FASD in the offspring. They found that late pregnancy increases in the ratios of two pro-inflammatory cytokines (IL-6 and TNF- α) to the anti-inflammatory cytokine IL-10 had a negative impact on mental development at 12 months of age as well as psychomotor development at 6 and 12 months of age. Furthermore, maternal alcohol use was associated with an increase in cytokine levels throughout pregnancy; however, subjects whose anti-inflammatory IL-10 levels in the third trimester did not increase to maintain a proper balance of pro- and anti-inflammatory cytokines had an elevated risk of having a child with FASD. These results extend findings in animal models and support the premise that an imbalance between pro- and anti-inflammatory maternal cytokines may contribute to neurobehavioral impairments of, and alter the risk for, FASD.

Excessive alcohol consumption has been shown to increase serum plasma levels of numerous immune cytokines. Maternal immune activation and elevated cytokines have been implicated in certain neurological disorders (e.g., autism and schizophrenia) in the offspring. We investigated the hypothesis that elevated cytokines during pregnancy are a risk factor in women who gave birth to a child with Fetal Alcohol Spectrum Disorder (FASD) or a child with neurobehavioral impairment, regardless of prenatal alcohol exposure. Moderate to heavy alcohol-exposed (AE) (N = 149) and low or no alcohol-exposed (LNA) (N = 92) women were recruited into the study during mid pregnancy (mean of 19.8 ± 5.8 weeks' gestation) in two regions of Ukraine: Khmelnytsky and Rivne. Maternal blood samples were obtained at enrollment into the study at early to mid-pregnancy and during a third-trimester follow-up visit and analyzed for plasma cytokines. Children were examined at 6 and/or 12 months of age and were classified as having FASD if their mothers reported alcohol use and if they had at least one standardized score (Bayley Scales of Infant Development II Mental Development Index [MDI], or Psychomotor Development Index [PDI]) below 85 with the presence or absence of physical features of FASD. In multivariate analyses of maternal cytokine levels in relation to infant MDI and PDI scores in the entire sample, increases in the ratio of TNF-α/IL-10 and IL-6/IL-10 were negatively associated with PDI scores at 6 months (p = 0.020 and p = 0.036, respectively) and 12 months (p = 0.043 and p = 0.029, respectively), and with MDI scores at 12 months (p = 0.013 and p = 0.050, respectively). A reduction in the odds ratio of having an FASD child was observed with increasing levels of IL-1β, IL-2, IL-4, IL-6, and IL-10 in early to mid-pregnancy and IL-1β and IL-10 during late pregnancy. However, women that failed to increase IL-10 levels in the third trimester in order to maintain the balance of pro- and anti-inflammatory cytokines had an elevated risk of having an FASD child, specifically a significant increase in the odds ratio of FASD with every one-unit log increase in late pregnancy TNF-α/IL-10 levels (aOR: 1.654, CI: 1.096-2.495, p = 0.017). These data support the concept that disruptions in the balance between pro- and anti-inflammatory cytokines may contribute to neurobehavioral impairment and alter the risk of FASD.

Prevalence of Fetal Alcohol Spectrum Disorders in 4 US Communities

Significance: In this study, May and colleagues used active-case ascertainment, the most reliable approach for estimating the prevalence of FASD, to determine new prevalence estimates among four U.S. communities with varied demographics. They observed prevalence estimates between 1 percent to 5 percent across the four regions. These new estimates are consistently higher than a recent meta-analysis of 6 studies from the United States with a pooled prevalence of 2 percent. Although their findings may not be generalizable to all U.S. communities, they are likely more accurate than previously reported estimates for the United States. Given that children with FASD often go undiagnosed or misdiagnosed, it is important for clinicians and researchers to be aware of the prevalence of FASD. 

IMPORTANCE: Fetal alcohol spectrum disorders are costly, life-long disabilities. Older data suggested the prevalence of the disorder in the United States was 10 per 1000 children; however, there are few current estimates based on larger, diverse US population samples. OBJECTIVE: To estimate the prevalence of fetal alcohol spectrum disorders, including fetal alcohol syndrome, partial fetal alcohol syndrome, and alcohol-related neurodevelopmental disorder, in 4 regions of the United States. DESIGN, SETTING, AND PARTICIPANTS: Active case ascertainment methods using a cross-sectional design were used to assess children for fetal alcohol spectrum disorders between 2010 and 2016. Children were systematically assessed in the 4 domains that contribute to the fetal alcohol spectrum disorder continuum: dysmorphic features, physical growth, neurobehavioral development, and prenatal alcohol exposure. The settings were 4 communities in the Rocky Mountain, Midwestern, Southeastern, and Pacific Southwestern regions of the United States. First-grade children and their parents or guardians were enrolled. EXPOSURES: Alcohol consumption during pregnancy. MAIN OUTCOMES AND MEASURES: Prevalence of fetal alcohol spectrum disorders in the 4 communities was the main outcome. Conservative estimates for the prevalence of the disorder and 95% CIs were calculated using the eligible first-grade population as the denominator. Weighted prevalences and 95% CIs were also estimated, accounting for the sampling schemes and using data restricted to children who received a full evaluation. RESULTS: A total of 6639 children were selected for participation from a population of 13 146 first-graders (boys, 51.9%; mean age, 6.7 years [SD, 0.41] and white maternal race, 79.3%). A total of 222 cases of fetal alcohol spectrum disorders were identified. The conservative prevalence estimates for fetal alcohol spectrum disorders ranged from 11.3 (95% CI, 7.8-15.8) to 50.0 (95% CI, 39.9-61.7) per 1000 children. The weighted prevalence estimates for fetal alcohol spectrum disorders ranged from 31.1 (95% CI, 16.1-54.0) to 98.5 (95% CI, 57.5-139.5) per 1000 children. CONCLUSIONS AND RELEVANCE: Estimated prevalence of fetal alcohol spectrum disorders among first-graders in 4 US communities ranged from 1.1% to 5.0% using a conservative approach. These findings may represent more accurate US prevalence estimates than previous studies but may not be generalizable to all communities.

Binge Drinking Above and Below Twice the Adolescent Thresholds and Health-Risk Behaviors

Significance: Previous research indicates that binge drinking thresholds for reaching a blood alcohol level (BAL) of .08% in youth are age- and gender-specific, and are lower than the adult binge thresholds. The current study explored whether drinking at levels at or more than twice the age-/gender-specific binge thresholds for adolescents was associated with increased health-risk behaviors among high-school students, compared with non-binge-drinking adolescents. The study found that 7 percent of high schoolers binged at levels greater than twice the age-/gender-specific thresholds, 9 percent binged at levels that were less than twice the thresholds but more than the binge thresholds, and 14 percent drank less than the binge thresholds. Significantly higher percentages of binge drinkers who consumed alcohol at or greater than twice the age-/gender-specific thresholds reported illegal drug and tobacco use, risky sexual and traffic behaviors, physical fights, suicide, less school-night sleep, and poorer school grades, compared with the other categories of drinkers. The findings suggest that adolescent alcohol-misuse screening should ask about the maximum number of drinks consumed per occasion and the frequency of such consumption. Also, because drinking at levels at or greater than twice the thresholds was a strong predictor of numerous health-risk behaviors, surveillance surveys should investigate which interventions can reduce consumption at these levels as well as related risky behaviors.

BACKGROUND: Underage drinking has been associated with health-risk behaviors: unintentional and unprotected sex; physical and sexual assault; suicide; homicide; traffic and other unintentional injuries; and overdoses. Five drinks consumed over 2 hours by adult males and 4 drinks by adult females typically produce blood alcohol levels (BALs) of ≥0.08%, which the National Institute on Alcohol Abuse and Alcoholism considers binge drinking. Being smaller, young adolescents can reach adult binge-drinking BALs of ≥0.08% with fewer drinks. Previous research indicates boys ages 9 to 13 would reach ≥0.08% with 3 drinks, 4 drinks at ages 14 to 15, and 5 drinks at ages ≥16. For girls, ≥0.08% is reached with ≥3 drinks at ages 9 to 17 and ≥4 drinks at ages ≥18. This study explores whether, among a national sample of high school students, adolescent binge drinking at ≥twice versus <twice the age-/gender-specific thresholds versus nonbinge drinking heightens associations of drinking with health-risk behaviors. METHODS: In 2015, the Youth Risk Behavior Survey asked a national probability sample of 15,624 high school students grades 9 to 12 (response rate 60%) about their past-month drinking and past-month or past-year health-risk behaviors. Logistic regressions with pairwise comparisons examined the association between different drinking levels and selected risk behaviors, adjusting for age, sex, race/ethnicity, and drinking frequency. RESULTS: Seven percent binged ≥twice and 9% <twice the age-/gender-specific thresholds, and 14% drank less than the binge thresholds. Significantly higher percentages of binge drinkers at ≥twice versus <twice the thresholds versus other drinkers reported illegal drug and tobacco use, risky sexual and traffic behaviors, physical fights, suicide, less school-night sleep, and poorer school grades. CONCLUSIONS: Adolescent alcohol misuse screening should query the maximum number of drinks consumed per occasion and frequency of such consumption. State and national surveillance surveys should include those questions to investigate which individual, family, school, community, and policy interventions reduce consumption beyond binge thresholds and related health-risk behaviors.

What "Likes" Have Got To Do With It: Exposure to Peers' Alcohol-Related Posts and Perceptions of Injunctive Drinking Norms

Significance: These findings suggest that underage college students, who lack ample first-hand experience observing alcohol use among close friends, may rely on social network sites, specifically the “Likes” attached to peers' alcohol-related posts, to estimate injunctive drinking norms. For first-year college students who have not yet initiated drinking, observing peers' alcohol-related posts receive abundant "likes" may increase perceptions of peer approval for risky drinking.

OBJECTIVE: Examine 1) whether observed social reinforcements (i.e., "likes") received by peers' alcohol-related social media posts are related to first-year college students' perceptions of peer approval for risky drinking behaviors; and 2) whether associations are moderated by students' alcohol use status. PARTICIPANTS: First-year university students (N = 296) completed an online survey in September 2014. METHOD: Participants reported their own alcohol use, friends' alcohol use, perceptions of the typical student's approval for risky drinking, and ranked 10 types of social media posts in terms of the relative numbers of "likes" received when posted by peers. RESULTS: Observed social reinforcement (i.e., "likes") for peers' alcohol-related posts predicted perceptions of peer approval for risky drinking behaviors among non-drinking students, but not drinking students. CONCLUSIONS: For first-year college students who have not yet initiated drinking, observing peers' alcohol-related posts to receive abundant "likes" may increase perceptions of peer approval for risky drinking.

The OPRM A118G Polymorphism: Converging Evidence Against Associations with Alcohol Sensitivity and Consumption

Significance: Numerous studies have associated the A118G functional genetic polymorphism in the mu-opioid receptor gene (OPRM1) with alcohol consumption and sensitivity; however, larger genome-wide association studies have yet to demonstrate an association between A118G and having a diagnosis of AUD. This study examined the effect of the A118G on alcohol self-administration, subjective response, and craving in a sample of social drinkers; the results indicated no significant effects. Also, analysis of alcohol consumption data in a larger sample of 965 participants of European ancestry found no relationship between OPRM1 genotype and alcohol consumption in participants with or without AUD. These findings suggest that there may not be an association between OPRM1 A118G genotype and alcohol consumption or sensitivity in individuals of European ancestry.

The endogenous opioid system may be involved in the development and maintenance of alcohol use disorder (AUD) and is a target for existing AUD pharmacotherapies. A functional polymorphism of the mu-opioid receptor gene (OPRM1 A118G, rs1799971) may alter the risk of developing AUD. Human laboratory studies have demonstrated that minor allele carriers self-administer more alcohol, show greater sensitivity to alcohol's effects, and exhibit increased alcohol-induced dopamine release. On the other hand, large genome-wide association studies and meta-analyses of candidate gene studies have not found an association between this genotype and alcohol dependence diagnosis. Given this discrepancy, the present study sought to verify whether OPRM1 A118G was associated with alcohol self-administration, subjective response to alcohol, and craving in a sample of 106 social drinkers of European ancestry who completed an intravenous alcohol self-administration session. We found no relationship between OPRM1 rs1799971 genotype and subjective response to alcohol or craving. OPRM1 genotype was not associated with total alcohol exposure or likelihood of attaining a binge-level exposure (80 mg%) during the intravenous alcohol self-administration session. Analysis of 90-day Timeline Followback interview data in a larger sample of 965 participants of European ancestry found no relationship between OPRM1 genotype and alcohol consumption in either alcohol dependent or non-dependent participants. These findings suggest that there may not be an association between OPRM1 rs1799971 genotype and alcohol consumption or sensitivity in individuals of European ancestry.

Advancing Analytic Approaches to Address Key Questions in Mechanisms of Behavior Change Research

Significance: Over the past two decades, there has been considerable interest in understanding the mechanisms of behavior change (MOBC) that underlie how behavioral treatments for AUD work. Mediation analysis frameworks have been the primary approach used to evaluate MOBC, but a greater understanding of how MOBC operate requires the application of advanced analytic techniques that consider the dynamic and non-linear change processes that take place in AUD treatment. This article highlights and reviews several statistical approaches (i.e., growth curve modeling, time-varying effect modeling, moderated mediation, and dynamic-systems modeling) that may enhance our understanding of MOBC in AUD treatment.

OBJECTIVE: Interest in studying mechanisms of behavior change (MOBCs) in substance use disorder (SUD) treatments has grown considerably in the past two decades. Much of this work has focused on identifying which variables statistically mediate the effect of SUD treatments on clinical outcomes. However, a fuller conceptualization of MOBCs will require greater understanding of questions that extend beyond traditional mediation analysis, including better understanding of when MOBCs change during treatment, when they are most critical to aiding the initiation or maintenance of change, and how MOBCs themselves arise as a function of treatment processes. METHOD: In the present study, we review why these MOBC-related questions are often minimally addressed in empirical research and provide examples of data analytic methods that may address these issues. We highlight several recent studies that have used such methods and discuss how these methods can provide unique theoretical insights and actionable clinical information. Results: Several statistical approaches can enhance the field’s understanding of the timing and development of MOBCs, including growth curve modeling, time-varying effect modeling, moderated mediation analysis, dynamic systems modeling, and simulation methods. CONCLUSIONS: Adopting greater diversity in methods for modeling MOBCs will help researchers better understand the timing and development of key change variables and will expand the theoretical precision and clinical impact of MOBC research. Advances in research design, measurement, and technology are key to supporting these advances. (Hallgren KA, Wilson AD, Witkiewitz K J Stud Alcohol Drugs 2018; 79: 182–189)

 

Development and Initial Characterization of a Novel Ghrelin Receptor CRISPR/CAS9 Knockout Wistar Rat Model

Significance: The hormone ghrelin is known for its role in regulating appetite and food intake, and previous studies have shown that ghrelin also involved in the brain's reward and stress pathways. The current study describes the development of a novel transgenic rat model lacking the ghrelin receptor that will enable future research on the role of the ghrelin system in substance use disorders and other behaviors.

BACKGROUND/OBJECTIVES: Ghrelin, a stomach-derived hormone implicated in numerous behaviors including feeding, reward, stress, and addictive behaviors, acts by binding to the growth hormone secretagogue receptor (GHSR). Here, we present the development, verification, and initial characterization of a novel GHSR knockout (KO) Wistar rat model created with CRISPR genome editing. METHODS: Using CRISPR/Cas9, we developed a GHSR KO in a Wistar background. Loss of GHSR mRNA expression was histologically verified using RNAscope in wild-type (WT; n = 2) and KO (n = 2) rats. We tested the effects of intraperitoneal acyl-ghrelin administration on food consumption and plasma growth hormone (GH) concentrations in WT (n = 8) and KO (n = 8) rats. We also analyzed locomotion, food consumption, and body fat composition in these animals. Body weight was monitored from early development to adulthood. RESULTS: The RNAscope analysis revealed an abundance of GHSR mRNA expression in the hypothalamus, midbrain, and hippocampus in WTs, and no observed probe binding in KOs. Ghrelin administration increased plasma GH levels (p = 0.0067) and food consumption (p = 0.0448) in WT rats but not KOs. KO rats consumed less food overall at basal conditions and weighed significantly less compared with WTs throughout development (p = 0.0001). Compared with WTs, KOs presented higher concentrations of brown adipose tissue (BAT; p = 0.0322). CONCLUSIONS: We have verified GHSR deletion in our KO model using histological, physiological, neuroendocrinological, and behavioral measures. Our findings indicate that GHSR deletion in rats is not only associated with a lack of response to ghrelin, but also associated with decreases in daily food consumption and body growth, and increases in BAT. This GHSR KO Wistar rat model provides a novel tool for studying the role of the ghrelin system in obesity and in a wide range of medical and neuropsychiatric disorders.

Unique Treatment Potential of Cannabidiol for the Prevention of Relapse to Drug Use: Preclinical Proof of Principle

Significance: This study supports the therapeutic potential of cannabidiol (CBD), a non-psychoactive constituent of cannabis, in preventing alcohol relapse. Using animal models, the researchers demonstrated beneficial effects of CBD on drug-seeking behavior, anxiety, and impulsivity, as well as long-lasting effects with only brief treatment. The results suggest that CBD can target concurrent behaviors associated with relapse risk, which may be more effective than targeting a single behavior.

BACKGROUND: Cannabidiol (CBD), the major non-psychoactive constituent of Cannabis sativa, has received attention for therapeutic potential in treating neurologic and psychiatric disorders. Recently, CBD has also been explored for potential in treating drug addiction. Substance use disorders are chronically relapsing conditions and relapse risk persists for multiple reasons including craving induced by drug contexts, susceptibility to stress, elevated anxiety, and impaired impulse control. Here, we evaluated the “anti-relapse” potential of a transdermal CBD preparation in animal models of drug seeking, anxiety and impulsivity. Rats with alcohol or cocaine self-administration histories received transdermal CBD at 24 h intervals for 7 days and were tested for context and stress-induced reinstatement, as well as experimental anxiety on the elevated plus maze. Effects on impulsive behavior were established using a delay-discounting task following recovery from a 7-day dependence-inducing alcohol intoxication regimen. CBD attenuated context-induced and stress-induced drug seeking without tolerance, sedative effects, or interference with normal motivated behavior. Following treatment termination, reinstatement remained attenuated up to ≈5 months although plasma and brain CBD levels remained detectable only for 3 days. CBD also reduced experimental anxiety and prevented the development of high impulsivity in rats with an alcohol dependence history. The results provide proof of principle supporting potential of CBD in relapse prevention along two dimensions CBD: beneficial actions across several vulnerability states, and long-lasting effects with only brief treatment. The findings also inform the ongoing medical marijuana debate concerning medical benefits of non-psychoactive cannabinoids and their promise for development and use as therapeutics.

The Role of Aging, Drug Dependence, and Hepatitis C Comorbidity in Alcoholism Cortical Compromise

Significance: Alcohol misuse over time can have deleterious effects on brain structure and function.  Comorbid factors such as drug dependence or hepatitis C infection may also play a role. An often-overlooked comorbid factor is the aging process. The current study examined changes in regional brain volumes in alcohol-dependent individuals and age-matched controls ages 25 to 75 who received one or more magnetic resonance imaging (MRI) scans over a 14-year period. Individuals in the alcohol-dependent group had significant age-related changes, most prominently in the frontal cortex, beyond the normal aging effects seen in matched controls. Drug dependence or hepatitis C infection compounded the alcohol-related effects. These findings suggest that alcohol misuse contributes to accelerated age-related impairments in brain function. 

IMPORTANCE: The prevalence of alcohol misuse increased substantially over a decade in adults, particularly in those aged 65 years or older. Ramifications for brain structural integrity are significant, especially in older adults. OBJECTIVES: To combine cross-sectional, longitudinal data to test age-alcoholism interactions and examine the association between prevalent comorbidities (drug dependence and hepatitis C virus [HCV] infection) and cortical volume deficits in alcohol dependence. DESIGN, SETTING, AND PARTICIPANTS: During 14 years, 826 structural magnetic resonance images were acquired in 222 individuals with alcohol dependence and 199 age-matched control participants (aged 25-75 years at initial study), parcellated with a common atlas, and adjusted for brain volume. Longitudinal data were available on 116 participants with alcoholism and 96 control participants. DSM-IV criteria determined alcohol and drug diagnoses; serology testing determined HCV status. The study was conducted at SRI International and Stanford University School of Medicine from April 11, 2003, to March 3, 2017. MAIN OUTCOMES AND MEASURES: Magnetic resonance imaging-derived regional cortical volumes corrected for supratentorial volume and sex. RESULTS: Of the 222 participants with alcoholism, 156 (70.3%) were men; mean (SD) age was 48.0 (10.0) years; the mean age for the 199 control participants was 47.6 (14.0) years. Participants with alcohol dependence had volume deficits in frontal (t = -5.732, P < .001), temporal (t = -3.151, P = .002), parietal (t = -5.063, P < .001), cingulate (t = -3.170, P = .002), and insular (t = -4.920, P < .001) cortices; deficits were prominent in frontal subregions and were not sex dependent. Accelerated aging occurred in frontal cortex (t = -3.019, P < .02) and precentral (t = -2.691, P < .05) and superior gyri (t = -2.763, P < .05) and could not be attributed to the amount of alcohol consumed, which was greater in younger-onset than older-onset participants with alcoholism (t = 6.1191, P < .001). Given the high drug-dependence incidence (54.5%) in the alcoholism group, analysis examined drug subgroups (cocaine, cannabis, amphetamines, opiates) compared with drug-dependence-free alcoholism and control groups. Although the alcohol plus cocaine (t = -2.310, P = .04) and alcohol plus opiate (t = -2.424, P = .04) groups had smaller frontal volumes than the drug-dependence-free alcoholism group, deficits in precentral (t = -2.575, P = .01), supplementary motor (t = -2.532, P = .01), and medial (t = -2.800, P = .01) volumes endured in drug-dependence-free participants with alcoholism compared with control participants. Those with HCV infection had greater deficits than those without HCV infection in frontal (t = 3.468, P = .01), precentral (t = 2.513, P = .03), superior (t = 2.533, P = .03), and orbital (t = 2.506, P = .03) volumes, yet total frontal (t = 2.660, P = .02), insular (t = 3.526, P = .003), parietal (t = 2.414, P = .03), temporal (t = 3.221, P = .005), and precentral (t = 3.180, P = .01) volume deficits persisted in the uninfected participants with alcoholism compared with control participants with known HCV status. CONCLUSIONS AND RELEVANCE: Drug dependence and HCV infection compounded deleterious effects of alcohol dependence on frontal cortical volumes but could not account for the frontally distributed volume deficits in the drug-free participants with alcoholism. We speculate that age-alcohol interactions notable in frontal cortex put older adults at heightened risk for age-associated neurocompromise even if alcohol misuse is initiated later in life.

Working Memory Training Improves Alcohol User’s Episodic Future Thinking: A Rate-Dependent Analysis

Significance: One of the hallmarks of addictive behavior is the inability to postpone immediate rewards (e.g., consuming the drink in front of you) and to discount or not select potentially larger rewards that occur later in time, also known as delay discounting. The current study used working memory training in alcohol-dependent individuals to reduce delay discounting and expand their temporal window for future rewards. Working memory training significantly improved episodic future thinking in alcohol-dependent individuals who had the highest discounting rates at baseline. This study suggests that working memory training can have the beneficial effect of improving the ability to postpone immediate awards in individuals with alcohol dependence. 

BACKGROUND: Episodic thinking, whether past or future, uses similar neural machinery, and individuals with alcohol dependence have clear challenges with both. Moreover, alcohol-dependent individuals' narrowed temporal window likely gives rise to greater valuation of immediate rewards. We aimed to strengthen working memory (WM) in alcohol-dependent individuals and measure performance on near-transfer (novel WM) and far-transfer delay discounting (DD) tasks, including episodic future thinking (EFT) performance. Importantly, heterogeneous intervention responses could obscure a treatment effect due to individuals' baseline differences. Therefore, we considered WM, DD, and EFT DD scores using rate-dependent analyses. METHODS: A total of 50 alcohol-dependent individuals received either 20 active (Trained) or sham (Control) WM training sessions using the Cogmed adaptive WM training program. Participants completed a near-transfer novel WM task and far-transfer DD and EFT DD tasks before and after training. RESULTS: Active WM training improved performance on the near-transfer task. As determined by Oldham's correlation [rmean(x,y), y - x], initially low near-transfer task scores improved more than initially high scores (i.e., rate dependence) in the Trained group only. Moreover, Trained group individuals with the highest rates of EFT DD at baseline rate-dependently decreased following training, whereas WM training had no effect on DD alone. CONCLUSIONS: These data support the notion that WM training improves near-transfer task performance and may enhance the effects of EFT DD in a subset of alcohol-dependent individuals trapped within the narrowest temporal window. Rate-dependent changes highlight that we should attend to baseline performance to better identify individuals who would most benefit from an intervention.
