Psychosocial and medication interventions to stop or reduce alcohol consumption during pregnancy.

BACKGROUND: Despite the known harms, alcohol consumption is common in pregnancy. Rates vary between countries, and are estimated to be 10% globally, with up to 25% in Europe. OBJECTIVES: To assess the efficacy of psychosocial interventions and medications to reduce or stop alcohol consumption during pregnancy. SEARCH METHODS: We searched the Cochrane Drugs and Alcohol Group Specialised Register (via CRSLive), Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, Web of Science, and PsycINFO, from inception to 8 January 2024. We also searched for ongoing and unpublished studies via ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). All searches included non-English language literature. We handsearched references of topic-related systematic reviews and included studies. SELECTION CRITERIA: We included randomised controlled trials that compared medications or psychosocial interventions, or both, to placebo, no intervention, usual care, or other medications or psychosocial interventions used to reduce or stop alcohol use during pregnancy. Our primary outcomes of interest were abstinence from alcohol, reduction in alcohol consumption, retention in treatment, and women with any adverse event. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures. MAIN RESULTS: We included eight studies (1369 participants) in which pregnant women received an intervention to stop or reduce alcohol use during pregnancy. In one study, almost half of participants had a current diagnosis of alcohol use disorder (AUD); in another study, 40% of participants had a lifetime diagnosis of AUD. Six studies took place in the USA, one in Spain, and one in the Netherlands. All included studies evaluated the efficacy of psychosocial interventions; we did not find any study that evaluated the efficacy of medications for the treatment of AUD during pregnancy. Psychosocial interventions were mainly brief interventions ranging from a single session of 10 to 60 minutes to five sessions of 10 minutes each. Pregnant women received the psychosocial intervention approximately at the end of the first trimester of pregnancy, and the outcome of alcohol use was reassessed 8 to 24 weeks after the psychosocial intervention. Women in the control group received treatment as usual (TAU) or similar treatments such as comprehensive assessment of alcohol use and advice to stop drinking during pregnancy. Globally, we found that, compared to TAU, psychosocial interventions may increase the rate of continuously abstinent participants (risk ratio (RR) 1.34, 95% confidence interval (CI) 1.14 to 1.57; I2 =0%; 3 studies; 378 women; low certainty evidence). Psychosocial interventions may have little to no effect on the number of drinks per day, but the evidence is very uncertain (mean difference -0.42, 95% CI -1.13 to 0.28; I2 = 86%; 2 studies; 157 women; very low certainty evidence). Psychosocial interventions probably have little to no effect on the number of women who completed treatment (RR 0.98, 95% CI 0.94 to 1.02; I2 = 0%; 7 studies; 1283 women; moderate certainty evidence). None of the included studies assessed adverse events of treatments. We downgraded the certainty of the evidence due to risk of bias and imprecision of the estimates. AUTHORS' CONCLUSIONS: Brief psychosocial interventions may increase the rate of continuous abstinence among pregnant women who report alcohol use during pregnancy. Further studies should be conducted to investigate the efficacy and safety of psychosocial interventions and other treatments (e.g. medications) for women with AUD. These studies should provide detailed information on alcohol use before and during pregnancy using consistent measures such as the number of drinks per drinking day. When heterogeneous populations are recruited, more detailed information on alcohol use during pregnancy should be provided to allow future systematic reviews to be conducted. Other important information that would enhance the usefulness of these studies would be the presence of other comorbid conditions such as anxiety, mood disorders, and the use of other psychoactive substances.

[Disulfiram encephalopathy: an underrecognized complication of accidental overdose]. / Disulfiramencefalopathie: een mogelijke complicatie bij accidentele overdosering.

In this paper we discuss the case of a 52-year-old man who consulted the emergency department because of confusion. Based on anamnesis, clinical presentation, various technical investigations and recovery after discontinuation of disulfiram, the diagnosis of disulfiram encephalopathy is made. This is a less common but serious complication of a frequently used therapy and underscores the importance of early recognition and careful but also controlled prescription of disulfiram. We describe the pathophysiology behind this complication and reflect on some important numbers.

Characterizing alcohol cue reactive and non-reactive individuals with alcohol use disorder.

PURPOSE: Exposure to alcohol-related cues is thought to elicit a conditional response characterized by increased craving in individuals with alcohol use disorder (AUD). In the context of AUD research, it is important to consider that not all individuals with an AUD are alcohol cue reactive. This study systematically examined subjective alcohol cue reactivity and its clinical and drinking correlates in individuals with an AUD enrolled in a human laboratory pharmacotherapy trial. METHODS: Individuals with current moderate-to-severe AUD (N = 52) completed a standard alcohol cue exposure paradigm and individual difference assessments as part of a human laboratory pharmacotherapy trial (NCT04249882). We classified participants as cue reactive (CR+) and cue non-reactive (CR-), as indicated by self-reported, subjective alcohol urge, and examined group differences in baseline clinical characteristics and drinking outcomes over the course of the trial. RESULTS: Twenty participants (38%) were identified as CR+, while 32 participants (62%) were identified as CR-. The CR+ and CR- groups did not differ in baseline drinking and AUD clinical characteristics, but the groups differed in race composition (p = 0.02) and smoking prevalence (p = 0.04) such that the CR+ group had lower prevalence of smokers. The CR+, compared with the CR-, group drank more during the trial titration period (p = 0.03). Both groups reduced drinking across the trial (p's < 0.001), but the CR+ group exhibited a smaller reduction in drinking, compared with the CR- group (time x group, p = 0.029; CR-, p < 0.0001; CR+: p = 0.01). CONCLUSION: Results indicate that cue reactivity is a heterogenous construct. Recognizing this heterogeneity, and the clinical factors associated with it, is critical to advancing this paradigm as an early efficacy marker in AUD research.

Medications for Alcohol Use Disorder.

Excessive alcohol use is a leading cause of preventable death in the United States, with alcohol-related deaths increasing during the pandemic. The Substance Abuse and Mental Health Services Administration recommends that physicians offer pharmacotherapy with behavioral interventions for patients diagnosed with alcohol use disorder. Several medications are available to help patients reduce drinking and maintain abstinence; however, in 2019, only 7.3% of Americans with alcohol use disorder received any treatment, and only 1.6% were prescribed medications to treat the disorder. Strong evidence shows that naltrexone and gabapentin reduce heavy-drinking days and that acamprosate prevents return-to-use in patients who are currently abstinent; moderate evidence supports the use of topiramate in decreasing heavy-drinking days. Disulfiram has been commonly prescribed, but little evidence supports its effectiveness outside of supervised settings. Other medications, including varenicline and baclofen, may be beneficial in reducing heavy alcohol use. Antidepressants do not decrease alcohol use in patients who do not have mood disorders, but they may help patients who meet criteria for depression to decrease their alcohol intake. Systematic policies are needed to expand the use of medications when treating alcohol use disorder in inpatient and outpatient populations.

Patient Perspectives on Pharmacotherapy of Alcohol Dependence.

INTRODUCTION: Pharmacotherapy with drugs like naltrexone or acamprosate is a well-evaluated element in the treatment of alcohol dependence (AD). However, in many countries, these medications are rarely administered. The objective of the present study was to identify from patients' perspective factors that prevent the initiation and compliance with pharmacological treatment of AD. METHODS: Patients from inpatient alcohol withdrawal treatment underwent a standardized interview. Questions included socio-demographic data, history of AD, treatment history, knowledge and personal experience regarding pharmacotherapy of AD, and personal views about the causes of AD. RESULTS: Three hundred patients (mean age 47.3 years, 27.7% female, mean duration of AD 8.9 years, 67% with a history of previous inpatient withdrawal treatment) were included. The majority of patients (58.7%) already knew drugs for the pharmacotherapy of AD. Thirty percent had ever used such medications, most often acamprosate. Except for disulfiram, pharmacotherapy of AD had lasted only a few weeks, on average. Medication usually had been applied without additional psychotherapy. No severe side effects were reported. Patients had often stopped pharmacotherapy on their own, when assuming they had reached stable abstinence. Openness to start pharmacotherapy for AD was currently stated by 67% of the total sample. In multiple logistic regression, openness was predicted by having a concept of AD as a medical disease and by a shorter duration of AD. DISCUSSION: To improve the administration of pharmacotherapy for AD implementation strategies should be systematically developed and evaluated with a focus on the concept of AD as a medical disease.

Pharmacotherapy for Alcohol Use Disorder: A Systematic Review and Meta-Analysis.

Importance: Alcohol use disorder affects more than 28.3 million people in the United States and is associated with increased rates of morbidity and mortality. Objective: To compare efficacy and comparative efficacy of therapies for alcohol use disorder. Data Sources: PubMed, the Cochrane Library, the Cochrane Central Trials Registry, PsycINFO, CINAHL, and EMBASE were searched from November 2012 to September 9, 2022 Literature was subsequently systematically monitored to identify relevant articles up to August 14, 2023, and the PubMed search was updated on August 14, 2023. Study Selection: For efficacy outcomes, randomized clinical trials of at least 12 weeks' duration were included. For adverse effects, randomized clinical trials and prospective cohort studies that compared drug therapies and reported health outcomes or harms were included. Data Extraction and Synthesis: Two reviewers evaluated each study, assessed risk of bias, and graded strength of evidence. Meta-analyses used random-effects models. Numbers needed to treat were calculated for medications with at least moderate strength of evidence for benefit. Main Outcomes and Measures: The primary outcome was alcohol consumption. Secondary outcomes were motor vehicle crashes, injuries, quality of life, function, mortality, and harms. Results: Data from 118 clinical trials and 20 976 participants were included. The numbers needed to treat to prevent 1 person from returning to any drinking were 11 (95% CI, 1-32) for acamprosate and 18 (95% CI, 4-32) for oral naltrexone at a dose of 50 mg/d. Compared with placebo, oral naltrexone (50 mg/d) was associated with lower rates of return to heavy drinking, with a number needed to treat of 11 (95% CI, 5-41). Injectable naltrexone was associated with fewer drinking days over the 30-day treatment period (weighted mean difference, -4.99 days; 95% CI, -9.49 to -0.49 days) Adverse effects included higher gastrointestinal distress for acamprosate (diarrhea: risk ratio, 1.58; 95% CI, 1.27-1.97) and naltrexone (nausea: risk ratio, 1.73; 95% CI, 1.51-1.98; vomiting: risk ratio, 1.53; 95% CI, 1.23-1.91) compared with placebo. Conclusions and Relevance: In conjunction with psychosocial interventions, these findings support the use of oral naltrexone at 50 mg/d and acamprosate as first-line pharmacotherapies for alcohol use disorder.

Repurposing disulfiram, an alcohol-abuse drug, in neuroblastoma causes KAT2A downregulation and in vivo activity with a water/oil emulsion.

Neuroblastoma, the most common type of pediatric extracranial solid tumor, causes 10% of childhood cancer deaths. Despite intensive multimodal treatment, the outcomes of high-risk neuroblastoma remain poor. We urgently need to develop new therapies with safe long-term toxicity profiles for rapid testing in clinical trials. Drug repurposing is a promising approach to meet these needs. Here, we investigated disulfiram, a safe and successful chronic alcoholism treatment with known anticancer and epigenetic effects. Disulfiram efficiently induced cell cycle arrest and decreased the viability of six human neuroblastoma cell lines at half-maximal inhibitory concentrations up to 20 times lower than its peak clinical plasma level in patients treated for chronic alcoholism. Disulfiram shifted neuroblastoma transcriptome, decreasing MYCN levels and activating neuronal differentiation. Consistently, disulfiram significantly reduced the protein level of lysine acetyltransferase 2A (KAT2A), drastically reducing acetylation of its target residues on histone H3. To investigate disulfiram's anticancer effects in an in vivo model of high-risk neuroblastoma, we developed a disulfiram-loaded emulsion to deliver the highly liposoluble drug. Treatment with the emulsion significantly delayed neuroblastoma progression in mice. These results identify KAT2A as a novel target of disulfiram, which directly impacts neuroblastoma epigenetics and is a promising candidate for repurposing to treat pediatric neuroblastoma.

Reported Risky Alcohol Use Among US Adults Prescribed 3 Classes of Chronic Alcohol-Interactive Medications.

This study uses data from the 2013­March 2020 National Health and Nutrition Examination Survey to assess contemporary patterns of risky alcohol use among adults taking high-risk alcohol-interactive medications (benzodiazepine receptor agonists, opioids, and antiepileptics).

Overview of Alcohol Use Disorder.

Alcohol is regularly consumed throughout most of the world, including by nearly half the U.S. population age 12 or older. Heavy drinking, which is also common, contributes to multiple adverse medical, psychiatric, and social outcomes and more than 140,000 deaths annually in the United States. It is the major risk factor for alcohol use disorder (AUD), whose current U.S. prevalence is 11%. However, AUD is undertreated, with less than 15% of individuals with a lifetime diagnosis receiving any treatment. Risk of AUD is nearly equally genetic and environmental. AUD is responsive to psychosocial treatments, including cognitive-behavioral therapy and motivational enhancement therapy. Alcohol affects multiple neurotransmitter systems, and thus pharmacotherapy for AUD is also effective. The three medications approved in the United States to treat AUD-disulfiram, naltrexone (oral and long-acting injectable formulations), and acamprosate-are underprescribed, despite being considered first-line treatments in clinical practice guidelines. Two medications not approved for treating AUD, topiramate and gabapentin, have shown efficacy in treating the disorder and are used off-label. Recent studies of novel drug candidates, including psychedelics and phosphodiesterase-4 inhibitors, are promising additions for the treatment of AUD, although they require further evaluation before being used clinically. Despite the growing availability of efficacious psychosocial and pharmacological treatments for AUD, it remains a highly stigmatized condition. Research aimed at enhancing the identification and treatment of AUD, including precision therapeutics, could broaden the acceptability of AUD treatment, benefiting affected individuals and their families and reducing the stigma associated with the disorder.

Medications for alcohol use disorder improve survival in patients with hazardous drinking and alcohol-associated cirrhosis.

BACKGROUND: Medications for alcohol use disorder (MAUD) are highly effective in achieving and maintaining abstinence in patients with alcohol use disorder (AUD). Our aim was to evaluate the effect of MAUD on all-cause mortality in patients with alcohol-associated cirrhosis and active alcohol use. METHODS: This was a retrospective cohort study of patients with alcohol-associated cirrhosis and high-risk alcohol use disorder in the Veterans Outcomes and Costs Associated with Liver Disease (VOCAL) database. Propensity score matching for exposure to MAUD (acamprosate or naltrexone) within a year after cirrhosis diagnosis was performed to account for potential confounders, and the association between MAUD and all-cause mortality was subsequently evaluated using Cox regression analysis. RESULTS: A total of 9131 patients were included, of whom 886 (9.7%) were exposed to MAUD (naltrexone: 520, acamprosate: 307, both medications: 59). The duration of MAUD exposure was >3 months in 345 patients (39%). The strongest positive predictor of MAUD prescription was an inpatient diagnosis code for AUD, followed by a concurrent diagnosis of depression; the strongest negative predictor was a history of cirrhosis decompensation. After propensity score matching (866 patients in each group) with excellent covariate balance (absolute standardized mean differences <0.1), MAUD exposure was associated with improved survival, with an HR of 0.80 relative to no MAUD exposure (95% CI: 0.67-0.97, p = 0.024). CONCLUSION: MAUD are underutilized in patients with alcohol-associated cirrhosis with high-risk alcohol use behavior but are associated with improved survival after adjustment for confounders such as the severity of liver disease, age, and engagement in the healthcare system.

Medications for the Treatment of Alcohol Dependence-Current State of Knowledge and Future Perspectives from a Public Health Perspective.

No single effective therapy for alcohol abuse has been found, despite it being a serious sociological and economic problem for hundreds of years. It seems difficult to find a single drug as a panacea for the alcohol problem due to the complexity of the pathophysiology of alcohol dependence. The purpose of this narrative review is to review existing and potentially future pharmaceuticals for the treatment of alcohol dependence in the most affordable way possible. Psychotherapy is the mainstay of treatment for alcoholism, while few drugs approved by legislators are available in the augmentation of this treatment, such as acamprosate, disulfiram, and naltrexone, approved by the FDA, and nalmefene by the EMA. There are recent reports in the literature on the possibility of using baclofen, topiramate, varenicline, and gabapentin in the treatment of alcohol dependence. Moreover, the results of recent clinical trials using psychoactive substances such as psilocybin and MDMA appear to be a breakthrough in the modern treatment of alcohol abuse. Despite this initial optimism, a lot of scientific effort is still needed before new pharmacological methods supporting the treatment of alcohol dependence syndrome will be widely available.

Impact of policy changes and drug shortages on acamprosate and naltrexone use in Ontario, Canada.

BACKGROUND: Acamprosate and naltrexone, evidence-based pharmacotherapies for alcohol use disorder (AUD), are publicly covered by the Ontario Drug Benefit (ODB) programs; however, their availability has changed over time, with expanded formulary access in July 2018, followed by an acamprosate shortage in February 2019 and ending in July 2020. We evaluated the impact of these events on the use of these medications in Ontario, Canada. METHODS: We conducted a time-series analysis among individuals with AUD dispensed acamprosate or naltrexone through the ODB from July 2016 to December 2020. Outcomes included monthly rates of those with AUD on therapy (primary), and rate of initiation (secondary) overall and by treatment type. We used autoregressive moving average models to evaluate the impact of expanded coverage and the acamprosate shortage on rates of use, and reported characteristics at first dispensation. RESULTS: Over the study period, 10,637 individuals (61.0% male) initiated acamprosate or naltrexone. Expanded coverage increased monthly utilization rates of acamprosate (p = 0.0004), naltrexone (p < 0.0001), and either AUD pharmacotherapy (p < 0.0001). The acamprosate shortage led to a 98.1% reduction in acamprosate use (p = 0.0003) but did not impact naltrexone (p = 0.51). Our secondary analysis yielded consistent results with respect to the shortage; however, the expanded formulary listing did not impact the rate of new acamprosate patients (p = 0.3). By December 2020, 5.3% of ODB recipients with AUD were accessing pharmacotherapy. CONCLUSIONS: Although coverage expansion increased access to medications that treat AUD, the shortage of acamprosate led to large reductions in its use, with no responsive increase in naltrexone prescribing.

Looking Back, Looking Forward: Current Medications and Innovative Potential Medications to Treat Alcohol Use Disorder.

This article is part of a Festschrift commemorating the 50th anniversary of the National Institute on Alcohol Abuse and Alcoholism (NIAAA). Established in 1970, first as part of the National Institute of Mental Health and later as an independent institute of the National Institutes of Health, NIAAA today is the world's largest funding agency for alcohol research. In addition to its own intramural research program, NIAAA supports the entire spectrum of innovative basic, translational, and clinical research to advance the diagnosis, prevention, and treatment of alcohol use disorder and alcohol-related problems. To celebrate the anniversary, NIAAA hosted a 2-day symposium, "Alcohol Across the Lifespan: 50 Years of Evidence-Based Diagnosis, Prevention, and Treatment Research," devoted to key topics within the field of alcohol research. This article is based on Dr. Mason's presentation at the event. NIAAA Director George F. Koob, Ph.D., serves as editor of the Festschrift.

Disulfiram's journey from rubber vulcanization to T-cell activation.

Disulfiram, a drug prescribed for the treatment of alcohol use disorders for more than 60 years, has recently been repurposed for cancer treatment. New work in The EMBO Journal now describes a disulfiram role in immunotherapy of cancer, involving direct binding to Lck to mediate activation of tumor-infiltrating T cells.

Identifying chronic alcoholism drug disulfiram as a potent DJ-1 inhibitor for cancer therapeutics.

As a key regulator involved in tumor development and progression, DJ-1 has been proposed as a potential therapeutic target against cancer. Also, the development of DJ-1 inhibitors holds great interests in cancer treatment. In the current study, by utilizing a small molecule covalent compounds library screening, we found that disulfiram (DSF), an FDA-approved chronic alcoholism drug, is a potent DJ-1 inhibitor. Glyoxalase assay and microscale thermophoresis analysis suggested that DSF exhibits strong inhibitory activity and high affinity to DJ-1 protein. Additionally, DSF similarly inhibited the methylglyoxal detoxification function of DJ-1 protein at the intracellular level. Notably, we discovered that DSF could significantly enhance N-(4-hydroxyphenyl) retinamide-based proliferation inhibition and apoptosis induction in different types of cancer cell lines, but not in normal tissue lines. Thus, our data suggest DSF functions as a potential inhibitor targeting DJ-1, which may provide a potential synergistic treatment option for cancer therapy.
