Macatee RJ, Cannon MJ, Schermitzler BS, Preston TJ, Afshar K. Biological sex and hormonal contraceptive associations with drug cue reactivity in cannabis use disorder. J Psychiatr Res 2024; 174:121-128. [PMID: 38626562 PMCID: PMC11195151 DOI: 10.1016/j.jpsychires.2024.04.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 02/18/2024] [Accepted: 04/09/2024] [Indexed: 04/18/2024]
Abstract
Biological sex differences in Cannabis Use Disorder (CUD) progression, cannabis withdrawal severity, and pharmacotherapy response have been reported, suggesting that CUD mechanisms may differ by sex. Drug cue reactivity is an established predictor of drug use behavior, but the literature on sex differences in drug cue reactivity is mixed, including in CUD. One possible moderator of sex differences in drug cue reactivity is hormonal contraceptive (HC) use. The aim of the present study was to test whether sex differences in neural cannabis cue reactivity and craving varied by female HC use in a CUD sample. As part of a larger study, 152 adults reporting frequent cannabis use completed a drug cue reactivity task during electrocenphalogram recording. Late positive potential (LPP) amplitude modulation by cannabis cues was used to measure neural cue reactivity. Craving after the cue reactivity task was also assessed. Males (n = 74) and naturally-cycling females (n = 26), who did not differ from each other, showed significantly greater LPP enhancement to cannabis vs. neutral cues compared to HC-using females (n = 52), an effect mostly driven by neutral cues. Craving was significantly higher in naturally-cycling but not HC-using females compared to males, but only in covariate-unadjusted analyses. Exploratory analyses of HC and menstrual phase characteristics indicate a progesterone-related mechanism may underlie HC effects on cannabis cue reactivity. The present study's results suggest that mixed findings on drug cue reactivity sex differences may be due to variability in HC use, which has implications for sex-specific models of CUD progression and treatment.

Abstract
Over the last 20 years, there has been an alarming increase in alcohol use and AUD prevalence among women, narrowing the historical gender gap. Concurrently, there has also been a significant rise in alcohol-associated liver disease (ALD) prevalence, severity, and mortality among women. Despite this, there are no recent reviews that have sought to evaluate both sex and gender differences at the intersection of AUD and ALD. In this narrative review, we address the escalating rates of ALD and AUD in the United States, with a specific focus on the disproportionate impact on women. Sex and gender play an important and well-known role in the pathogenesis and epidemiology of ALD. However, sex and gender are also implicated in the development and prevalence of AUD, as well as in the treatment of AUD, all of which have important consequences on the approach to the treatment of patients with ALD and AUD. A better understanding of sex and gender differences in AUD, ALD, and the intersection of the 2 is essential to enhance prevention, diagnosis, and management strategies. These data underscore the urgent need for awareness and preventive efforts to mitigate the potential long-term health consequences.

Pupillary response to percutaneous auricular vagus nerve stimulation in alcohol withdrawal syndrome: A pilot trial. Alcohol 2024; 114:61-68.

Abstract
BACKGROUND Autonomic symptoms in alcohol withdrawal syndrome (AWS) are associated with a sympathetic-driven imbalance of the autonomic nervous system. To restore autonomic balance in AWS, novel neuromodulatory approaches could be beneficial. We conducted a pilot trial with percutaneous auricular vagus nerve stimulation (pVNS) in AWS and hypothesized that pVNS will enhance the parasympathetic tone represented by a reduction of pupillary dilation in a parasympatholytic pharmacological challenge. METHODS Thirty patients suffering from alcohol use disorder, undergoing AWS, and stable on medication, were recruited in this open-label, single-arm pilot trial with repeated-measure design. Peripheral VNS (monophasic volt impulses of 1 msec, alternating polarity, frequency 1 Hz, amplitude 4 mV) was administered at the left cymba conchae for 72 h, followed by pupillometry under a tropicamide challenge. We assessed craving with a visual analog scale. We used pupillary mean as the dependent variable in a repeated-measures ANOVA (rmANOVA). RESULTS A repeated-measures ANOVA resulted in a significant difference for pupillary diameter across time and condition (F(2,116) = 27.97, p < .001, ηp2 > .14). Tukey-adjusted post hoc analysis revealed a significant reduction of pupillary diameter after pVNS. Alcohol craving was significantly reduced after pVNS (p < .05, Cohen's d = 1.27). CONCLUSION Our study suggests that pVNS activates the parasympathetic nervous system in patients with acute AWS, and that this activation is measurable by pupillometry. To this end, pVNS could be beneficial as a supportive therapy for AWS. Potential confounding effects of anti-craving treatment should be kept in mind.

Abstract
OBJECTIVES Alcohol misuse remains a major concern in college student populations and rates of risky and problematic drinking are specifically on the rise for women. One important factor that has been shown to be positively associated with substance use/misuse for women from historically marginalized or minoritized racial/ethnic backgrounds is exposure to racial discrimination and possible resulting traumatic stress reactions. Questions remain about the relationship between race-based traumatic stress and risky drinking particularly among diverse female college students who are at greater risk due to their marginalized status in their racial/ethnic and gender groups. DESIGN The current study examined race-based traumatic stress as a unique predictor of risky drinking when controlling for negative affectivity and general trauma symptoms, additional risk factors for risky drinking in women. RESULTS Hierarchical linear regressions revealed that race-based traumatic stress made a significant and unique contribution to the amount of variance in risky drinking, above negative affectivity, and general trauma symptoms. CONCLUSION These findings highlight the importance of considering experiences of racism as risk factors in substance use prevention and intervention, specifically for female college students from marginalized or minoritized racial/ethnic backgrounds.

Abstract
Objective: Compared to their male counterparts, women with alcohol use disorders (AUD) alone and those with symptoms of co-occurring emotional disorders (posttraumatic stress disorder, PTSD, and depression) are particularly likely to have increased alcohol craving in response to negative affect and daily stressors. Emotion dysregulation is one transdiagnostic construct that may underlie heightened craving in response to stress within this population. In a secondary data analysis, the current study examined emotion dysregulation as a mediator of the associations of posttraumatic stress symptoms (PTSS) and depression symptoms with heightened stress-induced alcohol craving, as measured in the lab. Given the overlap in symptoms, the relative associations of PTSD and depression symptom clusters with stress-induced craving were explored. Method: 50 women Veterans (84% White, 88% Non-Hispanic, Mage=45.68) attended two in-lab sessions. Self-report measures of emotion dysregulation, PTSD, and depression symptoms were administered at baseline. During session two, participants reported on alcohol craving and negative affect at baseline and again after a personalized stress induction procedure. Results: Emotion dysregulation mediated the association of greater PTSS with heightened stress-induced craving, although emotion dysregulation was not a mediator of the association between depression and stress-induced craving. Greater alcohol craving after the stress induction was positively associated with cognitive-affective symptoms in PTSD and depression (and not with other symptom clusters of these diagnoses, e.g., avoidance, somatic-vegetative symptoms). Conclusions: Emotion dysregulation may be a transdiagnostic factor that helps to explain greater alcohol cravings and drinking in stressful contexts among women Veterans with heightened symptoms of co-occurring emotional disorders.

Research protocol of the efficacy of probiotics for the treatment of alcohol use disorder among adult males: A comparison with placebo and acceptance and commitment therapy in a randomized controlled trial. PLoS One 2023; 18:e0294768. [PMID: 38051740 PMCID: PMC10697511 DOI: 10.1371/journal.pone.0294768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 10/30/2023] [Indexed: 12/07/2023] Open
Abstract
BACKGROUND AND AIM Primarily, this study compares the efficacy of probiotic and acceptance and commitment therapy (ACT) in alleviating the severity of alcohol craving and alcohol use disorder (AUD) among patients who had undergo two weeks of in-patient detoxification. Secondarily, this study compares the efficacy of probiotic and ACT in mitigating the severity of comorbid depression and anxiety symptoms; decreasing serum level of pro-inflammatory cytokines, such as interleukin 1β (IL-1β), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α); changing the event-related potential in electroencephalogram (EEG) and restoring microbiota flora in the gut of AUD patients. METHODS AND ANALYSIS Initially, during Phase I of the study, the serum level of IL-1β, IL-6 and TNF-α; ERP changes in the EEG and fecal microbiota content will be compared between 120 AUD patients and 120 healthy controls. Subsequently in Phase II of the study, 120 AUD patients will be randomized by stratified permuted block randomization into the probiotic, ACT and placebo groups in a 1:1:1 ratio. Participants in the probiotic and placebo groups will be administered one sachet per day of Lactobacillus spp. probiotic and placebo, respectively for 12 weeks. While those in the ACT group will receive one session per week of ACT for 8 weeks. Outcome measures will be administered at four timepoints, such as t0 = baseline assessment prior to intervention, t1 = 8 weeks after intervention began, t2 = 12 weeks after intervention and t3 = 24 weeks after intervention. Primary outcomes are the degrees of alcohol craving, alcohol withdrawal during abstinence and AUD. Secondary outcomes to be assessed are the severity of co-morbid depression and anxiety symptoms; the serum levels of IL-1β, IL-6 and TNF-α; changes in ERP and fecal microbiota content.

JMIR Form Res 2023; 7:e42194. [PMID: 37934561 PMCID: PMC10664013 DOI: 10.2196/42194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 01/23/2023] [Accepted: 09/28/2023] [Indexed: 11/08/2023] Open
Abstract
BACKGROUND Alcohol use disorder (AUD) has become a major global health problem. Therapy for this condition is still a great challenge. Recently, it has become increasingly evident that computer-based training is a valuable addition to the treatment of addictive disorders. OBJECTIVE This study aims to evaluate the web-based serious game SALIENCE (Stop Alcohol in Everyday Life-New Choices and Evaluations) as an add-on therapy for AUD. It combines the cue-exposure therapy approach with elements of decision-making training, enhanced by interactive panoramic images. The effects of SALIENCE training on levels of craving, attention, and cognitive bias are investigated. METHODS In a randomized controlled trial, 62 participants with AUD undergoing 3 weeks of an extended alcohol detoxification program were randomly allocated to an intervention and a control group. A total of 49 individuals (mean age 44.04 y; 17/49, 35% female) completed all sessions and were included in the analysis. Only pretreatment data were available from the other 13 patients. Participants answered questionnaires related to alcohol consumption and craving and completed neuropsychological tasks at the beginning of the study and 2 weeks later to evaluate levels of attention and cognitive biases. During the 2-week period, 27 of the participants additionally performed the SALIENCE training for 30 minutes 3 times a week, for a total of 6 sessions. RESULTS We observed a significant decrease in craving in both groups: the control group (mean 15.59, SD 8.02 on the first examination day vs mean 13.18, SD 8.38 on the second examination day) and the intervention group (mean 15.19, SD 6.71 on the first examination day vs mean 13.30, SD 8.47 on the second examination day; F1,47=4.31; P=.04), whereas the interaction effect was not statistically significant (F1,47=0.06; P=.80). Results of the multiple linear regression controlling for individual differences between participants indicated a significantly greater decrease in craving (β=4.12; t36=2.34; P=.03) with the SALIENCE intervention. Participants with lower drinking in negative situations reduced their craving (β=.38; t36=3.01; P=.005) more than people with higher drinking in negative situations. CONCLUSIONS The general effectiveness of SALIENCE training as an add-on therapy in reducing alcohol craving was not confirmed. Nevertheless, taking into account individual differences (gender, duration of dependence, stress, anxiety, and drinking behavior in different situations), it was shown that SALIENCE training resulted in a larger reduction in craving than without. Notably, individuals who rarely consume alcohol due to negative affect profited the most from SALIENCE training. In addition to the beneficial effect of SALIENCE training, these findings highlight the relevance of individualized therapy for AUD, adapted to personal circumstances such as drinking motivation.

Abstract
BACKGROUND Males consume more alcohol than females, and alcohol use disorder (AUD) is more prevalent in males than females. However, females progress faster to AUD. Sex differences in neural alcohol cue reactivity were previously observed in young social drinkers, indicating a role of hypersensitivity to alcohol-related cues in very early stages of addiction. To our knowledge, this is the first study on patients diagnosed with AUD to test sex differences in neural reactivity to alcohol cues in order to widen previous findings. METHODS We analyzed data from previous studies, using a well-established functional magnetic resonance imaging (fMRI) paradigm to compare neural reactivity to alcohol cues between 42 female and 124 male patients with AUD (mean age 45 and 46 years) in predefined regions of interest that were implicated by previous studies (ventral and dorsal striatum as well as caudate, putamen, amygdala, hippocampus, insula, anterior cingulate cortex, and medial prefrontal cortex) using independent samples t-tests. Post-hoc, effect size calculations were performed. RESULTS Throughout all nine regions of interest, we found no statistically significant sex differences in neural reactivity toward alcoholic pictures alone or in comparison to neutral pictures (p > 0.05, FDR-corrected). Post-hoc effect size estimates indicated a magnitude between 0.137 and 0.418 (Hedge's g) on alcohol reactivity to alcohol cues compared to neutral cues and indicate very small to less than medium effect sizes in the direction of higher cue reactivity in female patients. CONCLUSION Previous studies showed sex differences in neural alcohol cue reactivity in younger social and problematic alcohol drinkers, i.e., stronger striatal cue-reactivity in males. After correction for multiple comparisons, we did not observe significant sex differences in a cohort of middle-aged females and males with AUD. Sex differences that are present during early phases of addiction development might disappear at later stages of AUD and might thus be considered as clinically less relevant in patients with more severe AUD.

Childhood Trauma and Dissociation Correlates in Alcohol Use Disorder: A Cross-Sectional Study in a Sample of 587 French Subjects Hospitalized in a Rehabilitation Center. Brain Sci 2022; 12:brainsci12111483.

Abstract
This study aimed to determine whether dissociative symptoms and childhood trauma (CT) may help identify a specific subgroup of patients among those hospitalized for alcohol use disorder (AUD). We assessed 587 patients hospitalized for an AUD in a French addiction rehabilitation center (cross-sectional study) regarding dissociative symptoms (DES-taxon), childhood trauma (CTQ), depression (BDI), anxiety (STAI-state and STAI-trait), posttraumatic stress disorder (PTSD; PCL-5), and AUD symptoms (AUDIT). We ran a hierarchical cluster analysis and compared the clusters in terms of dissociation and CT, as well as AUD, depressive, anxiety, and PTSD symptoms. We identified three clusters of patients: (1) patients with low AUD severity and low dissociation (LALD); (2) patients with high AUD severity and low dissociation (HALD); (3) patients with high AUD severity and high dissociation (HAHD). Patients from the HAHD group had significantly higher dissociation and more severe depression, anxiety, and PTSD symptoms than those with LALD and HALD. They also reported more emotional and sexual abuse than those with LALD. Among patients with an AUD, those with high dissociation may constitute an independent subgroup that exhibits a higher prevalence for CT and higher AUD severity, as well as higher depression, anxiety, and PTSD symptoms. Patients with more severe AUD and associated psychiatric symptoms should be systematically screened for dissociation and provided with tailor-based treatments.

Abstract
Women with alcohol use disorder (AUD) often present to treatment with heightened negative emotionality, including negative affect, anxiety, stress, and depression. Negative emotionality might impact women's alcohol abstinence self-efficacy (AASE), or confidence in their ability to remain sober, which is an important predictor of treatment outcomes. It is also plausible that other variables, such as alcohol craving, influence AASE. The present work examined the indirect effect of negative emotionality on AASE via alcohol craving as a mediator cross-sectionally among a sample of women enrolled in AUD treatment reporting co-occurring depressive symptoms (N = 73). Participants completed baseline measures of negative emotionality (e.g. anxiety and depression symptoms, stress, negative affect), alcohol craving, and AASE. All indices of negative emotionality were positively correlated with each other and alcohol craving (r's ranging from 0.244 to 0.671) and all but depression were inversely associated with AASE (r's ranging from -0.341 to -0.234; p <.05). In separate simple mediation models, we found that alcohol craving mediated the association of each of the four measures of negative emotionality with AASE. Further longitudinal and experimental work is necessary to determine if teaching skills to cope with alcohol craving in the context of co-occurring negative emotionality might lead to better therapeutic outcomes.

Abstract
BACKGROUND A sizeable literature highlighted that negative affectivity and craving are both known to be implicated in relapses. OBJECTIVES The present study synthetized the existing litterature to determine strength of the interaction between negative affectivity and craving for substance-related disorders including illicit drugs, alcohol and tobacco. METHODS We conducted a systematic review in accordance with PRISMA guidelines followed by a meta-analysis. Online computer databases PubMed, PsycINFO and Web of Science were searched systematically and thoroughly. Jamovi 1.8.1 Current version was used to conduct meta-analysis. RESULTS Thirty studies were included in the review, and 14 of these, including 2257 subjects, were used for meta-analysis. The raw correlation ranged from 0.17 to 0.58, which indicated weak to moderate association between negative affects and craving. In total, approximately 90% of the selection revealed a positive correlation between negative affects and craving. Alcohol and tobacco use disorders have received the most attention. Additionally, negative affectivity was often defined as a transient state rather than a stable personality trait. CONCLUSIONS In both of our meta-analyses and in the narratively reported studies, we found that negative affectivity is an important component related to craving, but individual differences in craving reactivity existed.

Abstract
Alcohol use disorder (AUD) is a chronic relapsing disease associated with malnutrition, metabolic disturbances, and gut microbiota alterations that are correlated with the severity of psychological symptoms. This study aims at supplementing AUD patients with prebiotic fiber during alcohol withdrawal, in order to modulate the gut microbiota composition and to evaluate its effect on gastrointestinal tolerance, metabolism, and patient's behavior. A randomized, double-blind, placebo-controlled study included 50 AUD patients assigned to inulin versus maltodextrin daily supplementation for 17 days. Biological measurements (fecal microbial 16S rDNA sequencing, serum biology), dietary intake, validated psychological questionnaires, and gastrointestinal tolerance assessment were performed before and after the intervention. Inulin significantly decreased the richness and evenness and induced changes of 8 genera (q < 0.1) including Bifidobacterium and Bacteroides. Prebiotic had minor effects on gastrointestinal symptoms and nutritional intakes compared to placebo. All patients showed an improvement in depression, anxiety, and craving scores during alcohol withdrawal regardless of the intervention group. Interestingly, only patients treated with inulin significantly improved the sociability score and had an increased serum level of brain-derived neurotrophic factor. This pilot study shows that inulin is well tolerated and modulates the gut microbiota and the social behavior in AUD patients, without further improving other psychological and biological parameters as compared to placebo.

Augmented tendency to act and altered impulse control in alcohol use disorders. NEUROIMAGE-CLINICAL 2021; 31:102738. [PMID: 34198038 PMCID: PMC8255248 DOI: 10.1016/j.nicl.2021.102738] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/16/2021] [Revised: 05/14/2021] [Accepted: 06/20/2021] [Indexed: 11/22/2022]
Abstract
Action preparation relies on the operation of control processes that modulate the excitability of the corticospinal tract. On the one hand, excitatory processes prepare the motor system for the forthcoming response; the stronger these influences, the stronger the tendency to act. On the other hand, inhibitory influences allow to suppress inappropriate actions and, more generally, to ensure some sort of impulse control. Because an impairment in these processes could foster inappropriate drinking behavior, the present study aimed at evaluating the motor correlates of such excitatory and inhibitory influences in non-treatment seeking heavy drinkers (HDs) and inpatients suffering from severe alcohol use disorder (SAUDs). Besides, as cue-elicited craving might further alter these processes, we also assessed the impact of an alcohol-related exposure. To do so, 15 healthy controls (HCs), 15 HDs and 15 SAUDs performed a choice reaction time task after having been immersed in a neutral or an alcohol-related environment, using virtual reality videos. Importantly, single-pulse transcranial magnetic stimulation was applied over the left and the right primary motor cortex during the task to elicit motor-evoked potentials in a set of hand muscles allowing us to specifically probe the impact of excitatory and inhibitory processes on motor activity. Our data indicate that excitatory influences are particularly high in both HDs and SAUDs, especially in the dominant hand, an effect that was not observed in HCs. By contrast, inhibitory influences were found to be perfectly normal in HDs, while they were lacking in SAUDs. Furthermore, the alcohol-related exposure enhanced the level of self-reported craving, but this effect only arose in HDs and did not significantly alter the strength of excitatory and inhibitory influences. Overall, although these results have to be taken with caution due to the small sample sizes, this study suggests that enhanced excitatory processes characterize both HDs and SAUDs, while weaker inhibitory influences only concern SAUDs. Hence, an abnormally strong tendency to act could represent a common feature of hazardous drinking, leading individuals to excessive alcohol consumption, whereas deficient impulse control would be a hallmark of more severe forms of AUD, potentially due to the chronic neurotoxic effects of alcohol. Finally, although an alcohol-related exposure does not seem to affect excitatory and inhibitory processes at play during action preparation per se, future works should evaluate changes in corticospinal excitability during the preparation of responses specifically targeting alcohol-related cues.

Abstract
Zusammenfassung. Hintergrund: Feldtheoretische Überlegungen veranlassten uns, entgegen dem in Katamnesestudien üblichen Vorgehen, eine getrennte Auswertung für Frauen und Männer verschiedener Altersgruppen vorzunehmen. Unsere Fragestellung lautete, inwiefern sich je nach Geschlecht und Alter unterschiedliche Prädiktoren für Abstinenz ergeben? Methode: Katamnesestudie alkoholabhängiger Personen nach stationärer verhaltenstherapeutischer Behandlung, in der retrospektiv mittels binärer logistischer Regression und Mann-Whitney-U Tests Unterschiede zwischen zur Ein-Jahres-Katamnese rückfälligen und abstinenten Patientinnen (N=712) und Patienten (N=1019) getrennt für verschiedene Altersgruppen analysiert wurden. Zur Erreichung ausreichender Stichprobengrößen wurden die Altersgruppen mittels Quartilen gebildet: 19-41, 42-48, 49-54, 55-79 Jahre. Ergebnisse: Frauen und Männer unterschieden sich nicht in der Abstinenzquote, mit Ausnahme der über 54-jährigen. Mit zunehmendem Alter steigt bei beiden Geschlechtern die Wahrscheinlichkeit für Abstinenz. Signifikante Prädiktoren (p<.01) mit mittlerer Effektstärke für Rückfall waren: vorherige stationäre Entwöhnungsbehandlungen bei den 42- bis 48-jährigen Frauen (OR: 3.6) und den über 54-jährigen Männern (OR: 4.5) und psychische Belastung bei den 42- bis 54-jährigen Männern (r=0.30). Rückfallkritische motivationale Schemata waren hohe Werte der Unzufriedenheit im Bereich das „Leben genießen“ (r=31) und „Leistung“ (r=36) bei den über 54-jährigen Frauen, „Kontrolle haben“ (r=30) bei den 42- bis 48-jährigen Männern und „Alleinsein“ bei den 49- bis 54-jährigen Männern (r=30). Schlussfolgerungen: Unsere Ergebnisse sprechen für eine geschlechter- und alterssensible Forschung und Behandlung unter Einbeziehung sozioökonomischer Merkmale und motivationaler Schemata. Insbesondere bei den unter 42-jährigen Frauen und Männern besteht wegen der hohen Rückfallquote und fehlender Prädiktoren erhöhter Forschungsbedarf.

Transcriptomics identifies STAT3 as a key regulator of hippocampal gene expression and anhedonia during withdrawal from chronic alcohol exposure. Transl Psychiatry 2021; 11:298.

Abstract
Alcohol use disorder (AUD) is highly comorbid with depression. Withdrawal from chronic alcohol drinking results in depression and understanding brain molecular mechanisms that drive withdrawal-related depression is important for finding new drug targets to treat these comorbid conditions. Here, we performed RNA sequencing of the rat hippocampus during withdrawal from chronic alcohol drinking to discover key signaling pathways involved in alcohol withdrawal-related depressive-like behavior. Data were analyzed by weighted gene co-expression network analysis to identify several modules of co-expressed genes that could have a common underlying regulatory mechanism. One of the hub, or highly interconnected, genes in module 1 that increased during alcohol withdrawal was the transcription factor, signal transducer and activator of transcription 3 (Stat3), a known regulator of immune gene expression. Total and phosphorylated (p)STAT3 protein levels were also increased in the hippocampus during withdrawal after chronic alcohol exposure. Further, pSTAT3 binding was enriched at the module 1 genes Gfap, Tnfrsf1a, and Socs3 during alcohol withdrawal. Notably, pSTAT3 and its target genes were elevated in the postmortem hippocampus of human subjects with AUD when compared with control subjects. To determine the behavioral relevance of STAT3 activation during alcohol withdrawal, we treated rats with the STAT3 inhibitor stattic and tested for sucrose preference as a measure of anhedonia. STAT3 inhibition alleviated alcohol withdrawal-induced anhedonia. These results demonstrate activation of STAT3 signaling in the hippocampus during alcohol withdrawal in rats and in human AUD subjects, and suggest that STAT3 could be a therapeutic target for reducing comorbid AUD and depression.

Effects of ketogenic diet and ketone monoester supplement on acute alcohol withdrawal symptoms in male mice. Psychopharmacology (Berl) 2021; 238:833-844.

Abstract
RATIONALE After alcohol ingestion, the brain partly switches from consumption of glucose to consumption of the alcohol metabolite acetate. In heavy drinkers, the switch persists after abrupt abstinence, leading to the hypothesis that the resting brain may be "starved" when acetate levels suddenly drop during abstinence, despite normal blood glucose, contributing to withdrawal symptoms. We hypothesized that ketone bodies, like acetate, could act as alternative fuels in the brain and alleviate withdrawal symptoms. OBJECTIVES We previously reported that a ketogenic diet during alcohol exposure reduced acute withdrawal symptoms in rats. Here, our goals were to test whether (1) we could reproduce our findings, in mice and with longer alcohol exposure; (2) ketone bodies alone are sufficient to reduce withdrawal symptoms (clarifying mechanism); (3) introduction of ketogenic diets at abstinence (a clinically more practical implementation) would also be effective. METHODS Male C57BL/6NTac mice had intermittent alcohol exposure for 3 weeks using liquid diet. Somatic alcohol withdrawal symptoms were measured as handling-induced convulsions; anxiety-like behavior was measured using the light-dark transition test. We tested a ketogenic diet, and a ketone monoester supplement with a regular carbohydrate-containing diet. RESULTS The regular diet with ketone monoester was sufficient to reduce handling-induced convulsions and anxiety-like behaviors in early withdrawal. Only the ketone monoester reduced handling-induced convulsions when given during abstinence, consistent with faster elevation of blood ketones, relative to ketogenic diet. CONCLUSIONS These findings support the potential utility of therapeutic ketosis as an adjunctive treatment in early detoxification in alcohol-dependent patients seeking to become abstinent.

Abstract
Objectives Alcohol craving is often associated with mood symptoms and predicts alcohol use in individuals with alcohol dependence. However, little is known about the impact of mood symptoms on alcohol craving in comorbid mood disorders and alcohol dependence. This study examines the predictive value of depressive and anxiety symptoms for obsessive and compulsive aspects of alcohol craving in adults with comorbid Major Depressive Disorder (MDD) and Alcohol Dependence. Methods Fifty-five adults (47% female; mean age of 39.35 (SD=8.80)) with DSM-IV diagnoses of comorbid MDD and alcohol dependence were prospectively assessed over a six-month period. They completed the Hamilton Rating Scales for Depression and Anxiety, the Alcohol Timeline Followback, the Obsessive Compulsive Drinking Scale (OCDS), the Alcohol Dependence Scale (ADS), and the Addiction Severity Index (ASI). The linear mixed model analyses for repeated measures was used to test weather depressive and anxiety symptoms predict OCDS subscale scores. Results Depressive and anxiety symptoms were strongly associated with obsessive and compulsive subscales of the OCDS. Baseline ASI-alcohol scores were associated with both the obsessive and compulsive and with the obsessive subscale scores in the predictive model including depressive symptoms, and that including anxiety symptoms respectively. Conclusions Results suggest that depressive and anxiety symptoms predict obsessive and compulsive aspects of alcohol craving in adults with comorbid MDD and alcohol dependence. Assessing the severity of depressive and anxiety symptoms and alcohol use in this population may identify those more likely to experience intense alcohol craving states and at increased risk of relapse.

Abstract
The current article provides a brief summary of biopsychosocial gender differences in alcohol use disorder (AUD), then reviews existing literature on gender differences in treatment access, retention, outcomes, and longer-term recovery. Among psychotherapies for AUD, there is support for the efficacy of providing female-specific treatment, and for female-only treatment settings but only when female-specific treatment is included. However, despite mandates from the National Institutes of Health to do so, there is little work thus far that directly compares genders on outcomes of specific psychotherapies or pharmacotherapies for AUD. Although existing research has mixed findings on sex and gender differences in overall outcomes, there are more consistent findings suggesting different mechanisms of behavior change among men and women in AUD treatment and long-term recovery. Thus, more work is needed that attends to gender and sex differences, including planning studies that are structured to examine not only gender-differentiated outcomes in treatment response, but equally important, differences in treatment access and attendance as well as differences in mechanisms of change in drinking behavior.

Abstract
AIMS The aim of the present study was to evaluate the relation between anhedonia and depression in alcohol use disorders (AUD) during detoxification: Is trait anhedonia measured at the beginning of detoxification predictive of depressive symptoms observed at the end? Does state anhedonia recover during detoxification as depression does? Gender differences that have been previously observed for depression in AUD were also explored. METHODS 81 AUD inpatients were tested at T1 (day 1) and T2 (day 14-18) of withdrawal with the trait Physical Anhedonia Scale, the state anhedonia Snaith-Hamilton Pleasure Scale, the Beck depression inventory and the Spielberger State Anxiety Inventory and compared to 34 control participants, matched for age and gender. RESULTS AUD patients scored significantly higher than controls on depression, anxiety and state and trait anhedonia when they just entered the detoxification unit. Depression, anxiety and state anhedonia decreased between T1 and T2 in AUD patients. In women, state anhedonia at T1 was predictive of depressive symptoms at T2 over and above anxiety and depression at T1. CONCLUSION In AUD, state anhedonia recovers during detoxification, concurrently to other affective-related symptoms. However, in women, trait anhedonia predicts the level of depression at the end of detoxification, above and beyond anxiety. This finding stresses the importance of addressing anhedonia in the treatment of AUD and emphasizes the need for targeted interventions within clinical settings in this gender. Clinical consequences are discussed.

Abstract
BACKGROUND/OBJECTIVE Determining the predictive variables associated with levels of alcohol craving can ease the identification of patients who can benefit from treatments. This study aimed to describe changes (improvement or no change/deterioration) in alcohol craving levels and explore the predictors of these changes from admission to discharge in outpatients with alcohol use disorder (AUD) undergoing treatment-as-usual (TAU), or treatment-as-usual supplemented with virtual reality cue-exposure therapy (TAU + VR-CET). METHOD A prospective cohort study was conducted amongst 42 outpatients with AUD (n = 15 TAU + VR-CET and n = 27 TAU) from a clinical setting. Changes in the levels of alcohol craving between admission and discharge were assessed with the Multidimensional Alcohol Craving Scale. Sociodemographic characteristics (age, gender, education, and socioeconomic and civil status), cognitive-affective behavioral patterns (AUD severity, abstinence duration, psychiatric comorbidity, state anxiety, attentional bias, and substance use), and type of treatment (TAU + VR-CET and only TAU) were also evaluated. RESULTS The TAU + VR-CET group showed greater changes of improvement in the levels of alcohol craving than the TAU group (χ2 = 10.996; p = 0.001). Intragroup changes in alcohol craving from pre to post-treatment were significant in the TAU + VR-CET group (χ2 = 13.818; p = 0.003) but not within the TAU group (χ2 = 2.349; p = 0.503). The odds of an improvement in any of the craving levels between pre- and post-test was 18.18 (1/0.055) times higher in the TAU + VR-CET group with respect to the TAU group. The use of illicit drugs in the month prior to the test increased the odds of having a positive change by 18.18 (1/0.055) with respect to not having consumed. CONCLUSIONS Including VR-CET in TAU programs may provide benefits in the treatment of AUDs mainly among patients with intense alcohol craving and individuals having used illicit substances prior to treatment.

Zhang J, Hu Y, Wang Z, Wang M, Dong GH. Males are more sensitive to reward and less sensitive to loss than females among people with internet gaming disorder: fMRI evidence from a card-guessing task. BMC Psychiatry 2020; 20:357. [PMID: 32635911 PMCID: PMC7341652 DOI: 10.1186/s12888-020-02771-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 06/29/2020] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND Many studies have found an interesting issue in the Internet gaming disorder (IGD): males are always observed to be the majority. However, there are little research to exploring the differences in the neural mechanisms between males and females in decision-making process among people with IGD. Therefore, explore the reward/loss processing between different gender with IGD could help in understanding the underlying neural mechanism of IGD. METHODS Data from functional magnetic resonance imaging (fMRI) were collected from 111 subjects (IGD: 29 males, 25 females; recreational internet game user (RGU): 36 males, 21 females) while they were performing a card-guessing task. We collected and compared their brain features when facing the win and loss conditions in different groups. RESULTS For winning conditions, IGD group showed hypoactivity in the lingual gyrus than RGU group, male players showed hyperactivity in the left caudate nucleus, bilateral cingulate gyrus, right middle frontal gyrus (MFG), right precuneus and inferior parietal lobule relative to the females. And significant sex-by-group interactions results showed higher brain activities in the thalamus, parahippocampal gyrus and lower brain activities in Inferior frontal gyrus (IFG) were observed in males with IGD than females. For losing conditions, IGD group showed hypoactivity in the left lingual gyrus, parahippocampal gyrus and right anterior cingulate cortex (ACC) compared to the RGU group, male players showed hyperactive left caudate nucleus and hypoactive right middle occipital gyrus relative to females. And significant sex-by-group interactions results showed that compared to females with IGD, males with IGD showed decreased brain activities in the IFG and lingual gyrus. CONCLUSIONS First, there appeared to be no difference in reward processing between the IGD and RGU group, but IGD showed less sensitivity to loss. Secondly, male players showed more sensitivity to rewards and less sensitivity to losses. Last but not least, males and females showed opposite activation patterns in IGD degree and rewards/losses processing. And male IGD subjects are more sensitive to reward and less sensitive to loss than females, which might be the reason for the gender different rates on IGD.

A real-world study on clinical predictors of relapse after hospitalized detoxification in a Chinese cohort with alcohol dependence. PeerJ 2019; 7:e7547.

Abstract
BACKGROUND The relapse rate of alcohol dependence (AD) after detoxification is high, but few studies have investigated the clinical predictors of relapse after hospitalized detoxification in real-world clinical practice, especially among Chinese patients. METHODS This longitudinal cohort study followed up 122 AD patients who were discharged from January 1, 2016 to January 30, 2018 from their most recent hospitalization for detoxification. These patients were interviewed by telephone from May 20, 2017, to June 30, 2018, at least 6 months after discharge. During the interview, the relapse were assessed by using a revised Chinese version of the Alcohol Use Disorder Identification Test. Candidate predictors, such as therapeutic modalities during hospitalization and at discharge, medical history data related to alcohol use, and demographic information, were obtained from the medical records in the hospital information system. RESULTS During the 6-24 months (with a median of 9 months) follow-up period, the relapse rate was 53.3%. Individuals with a college education level and those who had not been treated with the brief comprehensive cognitive-motivational-behavioural intervention (CCMBI) were more likely than their counterparts to relapse after hospitalized detoxification, and their adjusted HRs (95% CIs) were 1.85 (1.09, 3.16) and 2.00 (1.16, 3.46), respectively. The CCMBI use predicted a reduction in the relapse rate by approximately one-fifth. CONCLUSION Undergoing the CCMBI during detoxification hospitalization and having less than a college-level education could predict a reduced risk of AD relapse. These findings provide useful information both for further clinical research and for real-world practice.

The histone deacetylase inhibitor suberoylanilide hydroxamic acid (SAHA) alleviates depression-like behavior and normalizes epigenetic changes in the hippocampus during ethanol withdrawal. Alcohol 2019; 78:79-87. [PMID: 30851364 PMCID: PMC6612300 DOI: 10.1016/j.alcohol.2019.02.005] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Revised: 02/14/2019] [Accepted: 02/26/2019] [Indexed: 12/27/2022]
Abstract
Withdrawal from chronic alcohol drinking can cause depression, leading to an inability to function in daily life and an increased risk for relapse to harmful drinking. Understanding the causes of alcohol withdrawal-related depression may lead to new therapeutic targets for treatment. Epigenetic factors have recently emerged as important contributors to both depression and alcohol use disorder (AUD). Specifically, acetylation of the N-terminal tails of histone proteins that package DNA into nucleosomes is altered in stress-induced models of depression and during alcohol withdrawal. The goal of this study was to examine depression-like behavior during alcohol withdrawal and associated changes in histone acetylation and expression of histone deacetylase 2 (HDAC2) in the hippocampus, a brain region critical for mood regulation and depression. Male Sprague-Dawley rats were treated with the Lieber-DeCarli ethanol liquid diet for 15 days and then underwent withdrawal. Rats were treated with the HDAC inhibitor, suberoylanilide hydroxamic acid (SAHA), during withdrawal and were tested for depression-like behavior. In a separate group of rats, the hippocampus was analyzed for mRNA and protein expression of HDAC2 and levels of histone H3 lysine 9 acetylation (H3K9ac) during chronic ethanol exposure and withdrawal. Rats undergoing ethanol withdrawal exhibited depression-like behavior and had increased HDAC2 and decreased H3K9ac levels in specific structures of the hippocampus. Treatment with SAHA during withdrawal ameliorated depression-like behavior and normalized changes in hippocampal HDAC2 and H3K9ac levels. These results demonstrate that ethanol withdrawal causes an altered epigenetic state in the hippocampus. Treatment with an HDAC inhibitor can correct this state and alleviate depression-like symptoms developed during withdrawal. Targeting histone acetylation may be a novel strategy to reduce ethanol withdrawal-induced depression.

Abstract
BACKGROUND Sex-related differences in the susceptibility, progression, and treatment response in alcohol-dependent subjects have been repeatedly reported. In this study, we aimed to investigate the associations of the sex-related hormone/protein levels with alcohol dependence (AD) and alcohol craving in male and female subjects. METHODS Plasma sex-related hormones (estradiol, estrone, total testosterone, progesterone, follicle stimulated hormone [FSH], luteinizing hormone), and sex hormone binding globulin were measured by mass spectrometry or automated immunoassays from 44 recently-abstained subjects (29 males and 15 females; mean age = 45.9 ± 15.6) meeting DSM-IV-TR criteria for AD and 44 age-, sex- and race-matched non-AD controls. Conditional logistic regression was conducted to examine the association of sex-related hormone and protein levels with AD risk, accounting for matching variables. Their associations with alcohol craving scales (Penn Alcohol Craving Scale and Inventory of Drug-Taking Situations) were assessed in AD subjects. RESULTS Plasma FSH level was significantly higher in AD males (10.3 ± 9.8 IU/L) than control males (8.0 ± 15.9 IU/L; p = 0.005, pcorrected = 0.035). We also found a significant inverse correlation of FSH level with propensity to drink in negative emotional situations (Spearman's rho=-.540; p = 0.021) and positive correlations between progesterone level and craving intensity (Spearman's rho=.464; p = 0.020) and between total testosterone level and propensity to drink under temptations (adjusted for no-drinking days; β=6.496; p = 0.041) in AD males. CONCLUSIONS These results suggest that FSH, progesterone, and testosterone levels may be associated with AD and alcohol craving in AD males. Future research is needed to replicate these findings and investigate the underlying biological mechanisms.

Abstract
The gastrointestinal tract is the natural habitat for a huge community of microorganisms, comprising bacteria, viruses, fungi and yeast. This microbial ecosystem codevelops with the host throughout life and is subject to a complex interplay that depends on multiple factors including host genetics, nutrition, life-style, stress, diseases and antibiotics use. The gut microbiota, that refers to intestinal bacteria, has profound influence on the host immune system, metabolism and nervous system. Indeed, intestinal bacteria supply the host with essential nutrients such as vitamins, metabolize bile acids and undigested compounds, defend against pathogen invasion, participate to the development of the intestinal architecture and the intestinal immune system and play an important role in the maintenance of the gut barrier function. More recently, the gut microbiota has been shown to influence brain functions, such as myelin synthesis, the blood-brain barrier permeability and neuroinflammatory responses but also mood and behavior. The cross-talk between microbes and the host implicates a vast array of signaling pathways that involve many different classes of molecules like metabolites produced by the bacteria from dietary or endogenous sources of carbohydrates and proteins (i.e. short-chain fatty acids (SCFAs), indole), neurotransmitters and inflammatory cytokines. This review will focus on the involvement of the gut microbiota in the pathophysiological aspects of alcohol dependence related to the gut barrier function, liver damage and psychological disturbances. We will also discuss the possibility to create new and realistic humanized animal models of alcohol dependence by the use of fecal transplantation.

Abstract
Background: Alcohol dependence is highly prevalent in the general population; some differences in alcohol use and dependence between women and men have been described, including outcomes and ranging from biological to social variables. This study aims to compare the severity of alcohol dependence with clinical and psychopathological characteristics between sexes. Methods: A cross-sectional descriptive study was conducted in alcohol-dependent outpatients; the recruitment period was 7 years. The assessment of these patients was carried out by obtaining sociodemographic characteristics and using the Semi-structured Clinical Interview for Axis I and II (SCID-I and SCID-II), European version of the Addiction Severity Index (EuropASI), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI) scales. Variables were compared and analyzed. Results: The sample was composed of 178 patients (74.2% males and 25.8% females) with a mean age of 46.52 ± 9.86. No sociodemographic differences were found between men and women. Females had a higher rate of suicide attempts and depression symptoms at the treatment onset. When results of EuropASI were compared, females had worse psychological and employment results than males. According to consumption variables, males had an earlier onset of alcohol use, had more regular alcohol use, and develop alcohol dependence earlier than females. Conclusions: According to results, there are sex-dependent differences (severity and other variables such as mood or suicide) in alcohol dependence. Thus, this may implicate the need of future specific research and treatment programs based on the specific necessities of each sex.

Abstract
Background: Alcohol craving is common among adolescents, stronger among those with more alcohol-related problems, and predicts drinking levels in their daily lives. Yet, the conditions that predict momentary changes in craving in real time among adolescents remain unclear. Objectives: This study examined the interactive effects of momentary risk-taking propensity and affect on adolescents' alcohol craving by leveraging ecological momentary assessment (EMA) methods. Methods: Participants were 29 adolescents ages 15-19 years (55% female; 69% White; 10% Black; 17% Hispanic); 45% met criteria for alcohol dependence. Following a laboratory session that captured self-report and behavioral assessments, including the well-established Balloon Analog Risk Task (BART), participants completed multiple daily assessments of alcohol craving, positive and negative affect, and risk propensity for approximately one week. Momentary risk propensity was captured in real-world settings via an EMA behavioral task ("Balloon Game"). Results: Mixed-effects models with EMA reports (Level 1) nested within participants (Level 2) revealed the majority (74%) of variability in "Balloon Game" performance was due to within-person, momentary, fluctuations. Greater momentary positive affect predicted increased alcohol craving, but only when participants exhibited heightened risk-taking propensity. Negative affect did not influence the relation between momentary risk-taking and craving. Conclusions/Importance: Momentary fluctuations in positive affect predicted acute increases in craving but only in moments when adolescents demonstrated higher levels of risk-taking propensity, as captured with an EMA-delivered behavioral task. Momentary risk-taking assessments offer new avenues to substantiate dominant theories on the driving mechanisms of craving and alcohol use among adolescents.

Abstract
Alcohol misuse is associated with thalamic dysfunction. The thalamus comprises subnuclei that relay and integrate information between cortical and subcortical structures. However, it is unclear how the subnuclei contribute to thalamic dysfunctions in problem drinking. We investigated resting-state functional connectivity (rsFC) of thalamic subregions in 107 nondependent drinkers (57 women), using masks delineated by white matter tractography. Thalamus was parceled into motor, somatosensory, visual, premotor, frontal association, parietal association, and temporal association subregions. Whole-brain linear regression, each against Alcohol Use Disorders Identification Test (AUDIT) and positive alcohol expectancy (AE) score with age as a covariate, was performed for each seed, for men and women combined, and separately. Overall, problem drinking was associated with increased thalamic connectivities, whereas AE was associated with a mixed pattern of increased and decreased connectivities. Motor, premotor, somatosensory, and frontal association thalamic connectivity with bilateral caudate head was positively correlated with AUDIT score in men and women combined. Connectivity of the right caudate head with frontal association and premotor thalamus was also positively correlated with AE score in men and women combined. In contrast, motor and premotor thalamic connectivity with a number of cortical and subcortical structures showed sex differences in the correlation each with AUDIT and AE score. In mediation analyses, AE score completely mediated the correlation between thalamic caudate connectivity and AUDIT score, whereas the model where AE contributed to problem drinking and, in turn, altered thalamic caudate connectivity was not supported. To conclude, thalamic subregional rsFCs showed both shared and distinct changes and sex differences in association with problem drinking and AE. Increased thalamic caudate connectivity may contribute to problem drinking via enhanced AE. The findings suggest the importance of examining thalamic subdivisions and sex in investigating the functional roles of thalamus in problem drinking.

Alcohol Clin Exp Res 2018; 42:634-645.

Abstract
BACKGROUND Craving and negative affect are distressing and commonly experienced during alcohol use disorder (AUD) treatment. Patients may assume that initiating abstinence will intensify their cravings and negative affect despite limited empirical data to support this assumption. This study extends and replicates, under improved methodological conditions, previous work that found reductions in daily craving associated with initiating abstinence. METHODS Seventy-eight adults (80.8% male, 57.1% Caucasian) in a clinical trial testing prazosin for AUD provided daily reports of drinking, craving, and negative affect for up to 12 weeks (mean = 64.77 daily reports). Participants were classified into 3 subgroups based on whether and when they initiated 14 days of continuous abstinence, including (i) "abstinence initiators" who quit drinking during treatment (n = 17), (ii) "already abstainers" who were abstinent at the start of treatment (n = 20), and (iii) "continued drinkers" who never initiated abstinence (n = 41). The timing and degree of change in craving and negative affect were compared across these groups using multivariate growth curve modeling. RESULTS All participant subgroups reported gradual reductions in craving over the course of treatment, with "abstinence initiators" reporting additional sudden reductions in craving upon initiating abstinence from alcohol. "Continued drinkers" reported higher levels of craving than "already abstainers" throughout the full course of treatment. Negative affect followed a different pattern of change, with "abstinence initiators" experiencing gradual reductions in negative affect after initiating abstinence but no changes prior to or immediately upon initiating abstinence, and with "already abstainers" and "continued drinkers" experiencing no changes in negative affect over time. CONCLUSIONS Initiating abstinence is associated with immediate reductions in craving, followed by gradual reductions in both craving and negative affect. Results provide insight into the timing and magnitude of changes in theoretically and clinically important variables and may help patients anticipate when to expect improvement in craving and negative effect.

Gender Differences in Anxiety and Depression before and after Alcohol Detoxification: Anxiety and Depression as Gender-Related Predictors of Relapse. Eur Addict Res 2018; 24:163-172. [PMID: 30016803 PMCID: PMC6172794 DOI: 10.1159/000490046] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2017] [Accepted: 05/09/2018] [Indexed: 11/19/2022]
Abstract
BACKGROUND/AIMS The aim of this prospective study was to estimate gender differences in anxiety, depression, and alcohol use severity among patients with alcohol use disorder (AUD) before and after detoxification program and within 12 months after discharge. METHODS AUD severity, state and trait anxiety, and depression were assessed in 187 patients entering an inpatient alcohol detoxification program. Follow-up assessments were performed at 6 and 12 months after discharge. A between- and within-subjects analyses explored gender differences. The predictive value of anxiety and depression for alcohol relapse was analyzed by logistic and linear regression in both genders. RESULTS Females had higher levels of anxiety and depression than males both at admission and after discharge. Trait anxiety and depression significantly increased 6 months after discharge in males and females respectively. Both state and trait anxiety levels at the 6-month follow-up predicted alcohol relapse at the 12-month follow-up in males. Conversely, in females, depression level at the 6-month follow-up was a predictor of relapse at the 12-month follow-up. CONCLUSIONS In both genders, the psychopathological dimension that showed the most significant worsening at 6-month follow-up (i.e., anxiety in males and depression in females) was found to be a significant predictor of relapse at the 12-month follow-up.
