RESUMO

BACKGROUND: More than a decade ago disulfiram lost its approval for use in Germany. Nonetheless, a considerable number of psychiatric hospital outpatient departments as well as practicing physicians continue to prescribe it. These professionals have formed the "Network for Alcohol Aversive Pharmacotherapy" (NAP) to maintain a high quality of this treatment approach. OBJECTIVE: To describe the current use of disulfiram with respect to patient numbers and characteristics, side effects, and use of concomitant multimodal treatment forms. MATERIAL AND METHODS: Since 2019 the NAP has conducted an annual retrospective survey among its members regarding the aforementioned parameters. RESULTS: From 2019 to 2023 a total of 1579 treatment cases were described by 33 centers, 152 patients reported a total of 241 drinking events, 26 of them resulting in hospitalization but none causing complications or permanent harm. The most frequent side effects, in descending order, were unpleasant body odor (2.5%), fatigue, male sexual dysfunction, mildly elevated liver enzymes, allergic skin reactions and polyneuropathy (0.8%). More than one quarter of the patients suffered from comorbid depression, and approximately 5% from ADHD, borderline or other personality disorders, trauma-related disorders and anxiety disorders, respectively. Of the patients 33% were treated with antidepressants and 12% with sedating antipsychotics. Various forms of concomitant group therapy were offered to 66% of the patients. CONCLUSION: Treatment with disulfiram is legally possible, generally well-tolerated and safe. It is offered in most treatment centers as part of a comprehensive treatment plan that includes multimodal treatment of comorbid psychiatric disorders.

RESUMO

BACKGROUND: Substance use disorders (SUD) often co-occur with attention deficit hyperactivity disorder (ADHD). Although the short-term effects of some specific interventions have been investigated in randomized clinical trials, little is known about the long-term clinical course of treatment-seeking SUD patients with comorbid ADHD. AIMS: This paper presents the protocol and baseline clinical characteristics of the International Naturalistic Cohort Study of ADHD and SUD (INCAS) designed and conducted by the International Collaboration on ADHD and Substance Abuse (ICASA) foundation. The overall aim of INCAS is to investigate the treatment modalities provided to treatment-seeking SUD patients with comorbid ADHD, and to describe the clinical course and identify predictors for treatment outcomes. This ongoing study employs a multicentre observational prospective cohort design. Treatment-seeking adult SUD patients with comorbid ADHD are recruited, at 12 study sites in nine different countries. During the follow-up period of nine months, data is collected through patient files, interviews, and self-rating scales, targeting a broad range of cognitive and clinical symptom domains, at baseline, four weeks, three months and nine months. RESULTS: A clinically representative sample of 578 patients (137 females, 441 males) was enrolled during the recruitment period (June 2017-May 2021). At baseline, the sample had a mean age (SD) of 36.7 years (11.0); 47.5% were inpatients and 52.5% outpatients; The most prevalent SUDs were with alcohol 54.2%, stimulants 43.6%, cannabis 33.1%, and opioids 14.5%. Patients reported previous treatments for SUD in 71.1% and for ADHD in 56.9%. Other comorbid mental disorders were present in 61.4% of the sample: major depression 31.5%, post-traumatic stress disorder 12.1%, borderline personality disorder 10.2%. CONCLUSIONS: The first baseline results of this international cohort study speak to its feasibility. Data show that many SUD patients with comorbid ADHD had never received treatment for their ADHD prior to enrolment in the study. Future reports on this study will identify the course and potential predictors for successful pharmaceutical and psychological treatment outcomes. TRIAL REGISTRATION: ISRCTN15998989 20/12/2019.

RESUMO

BACKGROUND: A link between attention-deficit/hyperactivity disorder (ADHD) and alcohol use disorder (AUD) has been widely demonstrated. In this study, we used neuroimaging to investigate the connectivity traits that may contribute to the comorbidity of these disorders. METHODS: The study included an AUD group (N = 18), an ADHD group (N = 17), a group with AUD + ADHD comorbidity (N = 12) and a control group (N = 18). We used resting-state functional connectivity in a seed-based approach in the default mode networks, the dorsal attention network, and the salience network. RESULTS: Within the default mode networks, all affected groups shared greater connectivity toward the temporal gyrus when compared to the control group. Regarding the dorsal attention network, the Brodmann area 6 presented greater connectivity for each affected group in comparison with the control group, displaying the strongest aberrations in the AUD + ADHD group. In the salience network, the prefrontal cortex showed decreased connectivity in each affected group compared to the control group. CONCLUSIONS: Despite the small and unequal sample sizes, our findings show evidence of common neurobiological alterations in AUD and ADHD, supporting the hypothesis that ADHD could be a risk factor for the development of AUD. The results highlight the importance of an early ADHD diagnosis and treatment to reduce the risk of a subsequent AUD.

RESUMO

International Consensus Statement for the Screening, Diagnosis, and Treatment of Adolescents with Concurrent Attention-Deficit/Hyperactivity Disorder and Substance Use Disorder Abstract. Background: Childhood attention-deficit/hyperactivity disorder (ADHD) is a risk factor for substance misuse and substance use disorder (SUD) in adolescence and (early) adulthood. ADHD and SUD also frequently co-occur in treatment-seeking adolescents, which complicates diagnosis and treatment and is associated with poor treatment outcomes. Research on the effect of treatment of childhood ADHD on the prevention of adolescent SUD is inconclusive, and studies on the diagnosis and treatment of adolescents with ADHD and SUD are scarce. Thus, the available evidence is generally not sufficient to justify robust treatment recommendations. Objective: The aim of the study was to obtain a consensus statement based on a combination of scientific data and clinical experience. Method: A modified Delphi study to reach consensus based upon the combination of scientific data and clinical experience with a multidisciplinary group of 55 experts from 17 countries. The experts were asked to rate a set of statements on the effect of treatment of childhood ADHD on adolescent SUD and on the screening, diagnosis, and treatment of adolescents with comorbid ADHD and SUD. Results: After 3 iterative rounds of rating and adapting 37 statements, consensus was reached on 36 of these statements representing 6 domains: general (n = 4), risk of developing SUD (n = 3), screening and diagnosis (n = 7), psychosocial treatment (n = 5), pharmacological treatment (n = 11), and complementary treatments (n = 7). Routine screening is recommended for ADHD in adolescent patients in substance abuse treatment and for SUD in adolescent patients with ADHD in mental healthcare settings. Long-acting stimulants are recommended as the first-line treatment of ADHD in adolescents with concurrent ADHD and SUD, and pharmacotherapy should preferably be embedded in psychosocial treatment. The only remaining no-consensus statement concerned the requirement of abstinence before starting pharmacological treatment in adolescents with ADHD and concurrent SUD. In contrast to the majority, some experts required full abstinence before starting any pharmacological treatment, some were against the use of stimulants in the treatment of these patients (independent of abstinence), while some were against the alternative use of bupropion. Conclusion: This international consensus statement can be used by clinicians and patients together in a shared decision-making process to select the best interventions and to reach optimal outcomes in adolescent patients with concurrent ADHD and SUD.

RESUMO

AIMS: This open-label study in patients with alcohol dependence and evidence of elevated liver stiffness and/or hepatic steatosis was designed to explore the efficacy of nalmefene (18 mg) in reducing alcohol consumption and its subsequent effects on a variety of clinically relevant liver parameters. METHODS: Adult patients with a diagnosis of alcohol dependence and evidence of elevated liver stiffness and/or hepatic steatosis (liver stiffness >6 kPa or controlled attenuation parameter (CAP) >215 dB/m as measured by transient elastography) were recruited at two study sites in Germany. During the 12-week treatment period, patients were instructed to take nalmefene each day they perceived a risk of drinking alcohol. RESULTS: All 45 enrolled patients took at least one dose of nalmefene and 39 completed the study. After 12 weeks of study treatment with nalmefene patients showed a reduction in alcohol consumption of -13.5 days/month heavy drinking days and -45.8 g/day total alcohol consumption. Most liver parameters showed modest changes at Week 12; there was a 13% decrease in liver stiffness and 10% reduction in CAP values. Results indicated non-significant negative associations between alcohol consumption and liver stiffness and/or CAP over this 12-week study. Nalmefene was generally well tolerated, and most adverse events were mild or moderate, the most frequent being dizziness. CONCLUSIONS: Patients treated with nalmefene for 12 weeks had reductions in alcohol consumption by ~50% relative to baseline and showed trends to improvement in liver stiffness and CAP.

RESUMO

INTRODUCTION: Alcohol dependence (AD) is frequently associated with attention-deficit/hyperactivity disorder (ADHD) as well as with posttraumatic stress disorder (PTSD). OBJECTIVE: Aim of this study was to investigate whether in patients with AD, ADHD is associated with an increased rate of exposure to potentially traumatic events (PTEs) and PTSD, with increased PTSD severity and higher impact on daily functioning. METHODS: Patients with AD were thoroughly assessed for ADHD during long-term residential treatment. Participants also completed the Posttraumatic Diagnostic Scale (PDS). The PDS is a 49-item self-report instrument that assesses exposure to different PTEs, DSM-IV criteria for PTSD, severity of PTSD, and related functional impairment. RESULTS: Of 341 patients with AD, 66 were diagnosed with ADHD (19%). ADHD was associated with a more frequent exposure to PTEs (88 vs. 65%, p < 0.001). In patients with PTEs (n = 237), odds for PTSD were higher in ADHD versus no-ADHD patients (OR 8.9, 95% CI 3.9-20.5). Furthermore, PTSD severity and functional impairment were increased in ADHD patients. CONCLUSIONS: ADHD in patients with AD is associated with a higher frequency of PTEs and PTSD with more severe and more impairing PTSD symptoms. In alcohol-dependent patients with ADHD, regular screening for PTSD should be considered.

RESUMO

AIMS: To examine the role of attention deficit/hyperactivity disorder (ADHD) and impulsive personality disorders in nicotine addiction severity among treatment-seeking substance use disorder (SUD) patients. METHODS: In a cross-sectional study, we examined data from the second International ADHD in Substance Use Disorders Prevalence Study (IASP-2) on 402 adults in SUD treatment from Puerto Rico, Hungary, and Australia using diagnostic interviews for ADHD, antisocial (ASP) and borderline (BPD) personality disorders, and the self-report Fagerström Test of Nicotine Dependence (FTND). We compared SUD patients with and without ADHD on nicotine addiction severity. We tested direct and indirect pathways from ADHD to nicotine addiction and mediation through ASP and BPD. RESULTS: Overall, 81.4% of SUD patients reported current cigarette smoking. SUD patients with ADHD had higher FTND scores and smoked more cigarettes than those without ADHD, with an earlier onset and more years of smoking. ASP mediated the effect of ADHD on all aspects of nicotine addiction severity, whereas BPD did so only on some aspects of nicotine addiction severity. CONCLUSIONS: SUD patients with comorbid ADHD show more severe nicotine addiction than those without, which is largely explained by comorbid impulsive personality disorders. In SUD patients, it is important to screen for adult ADHD and other psychiatric disorders, especially those with impulse control deficits such as ASP and BPD.

RESUMO

Among patients with substance use disorders (SUD), adult attention deficit hyperactivity disorder (ADHD) is one of the most frequently co-occuring disorder. Those SUD patients with comorbid ADHD show earlier onset of substance use, more severe SUD and poor treatment outcomes. Therefore, early recognition of ADHD is highly rele - vant within this patient population. The results of available screening instruments may lay the foundation of timely ADHD diagnosis. Considering the integrated treatment of patients with a dual ADHD+SUD diagnosis, the applica tion of combined pharmaco- and psychotherapy is recommended. Based on the evidence-and consensus-based suggestions, prescription of long-acting methylphenidate, extended-release amphetamines and atomoxetine with up-titration might be the best choice in the treatment of patients who are either unresponsive to standard dose or characterized by therapy resistance. The main purpose of this manuscript is to establish a standing-ground for the effective screening, diagnosis and treatment of ADHD+SUD patients.

RESUMO

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a common comorbidity in adult patients with substance use disorders (SUDs). The diagnostics and treatment of ADHD with SUD are often a challenge, also with respect to the prescription of stimulants. Recently, a group of international experts developed a consensus paper on the diagnosis and treatment of comorbid ADHD and SUD. In addition, the German S3 guidelines on ADHD have been published, which also give advice on the treatment of ADHD in comorbid SUD. The German S3 guidelines on alcohol-related disorders and methamphetamine-related disorders also address ADHD as a comorbidity. METHODS: Summary of consensus and guideline recommendations, supplemented with the most recent literature. CONCLUSION: In recent years new findings on the comorbidity of ADHD in patients with SUD have emerged. A series of screening and diagnostic instruments have meanwhile been evaluated in this patient group. The consensus paper and various guidelines therefore provide clinicians with specific help in detecting ADHD in patients with SUD and in conducting further diagnostics and treatment of both disorders. For example, the importance of stimulants in the treatment of patients with SUD and ADHD has significantly changed and first studies on psychotherapeutic interventions specific to this comorbidity are now available.

RESUMO

BACKGROUND: Routine screening using self report questionnaires for attention deficit/hyperactivity disorder (ADHD) in patients with alcohol use disorder is recommended due to its high prevalence and the time-consuming and demanding diagnostic assessment. The psychometric properties of such self-report instruments have hardly been investigated in this patient group. METHODS: The performance of the ADHD self-report scale (ADHD-SR) and the German short form of the Wender Utah Rating Scale (WURS-k) was determined in 402 patients with alcohol dependence during long-term residential weaning treatment. The diagnosis of adult ADHD had been confirmed in 85 of these patients using an extensive, standardized diagnostic procedure. RESULTS: The ADHD-SR at a cut-off ≥15 showed the best psychometric properties (sensitivity 75.3%, specificity 94.0%, positive predictive value, PPV 77.1%, negative predictive value, NPV 93.4%). The results of the WURS-k were unsatisfactory at the established cut-off ≥30 and also at lower cut-offs with more false positive screening results compared to the ADHD-SR. The combination of both instruments (ADHD-SR ≥ 15 and/or WURS-k ≥ 30) increased sensitivity (86.9%) albeit at the expense of a higher rate of false positive screening results (specificity 87.7%, PPV 65.2%). CONCLUSION: The ADHD-SR is a suitable instrument for routine screening of ADHD in alcohol dependent patients. To improve sensitivity, a lower cut-off (≥15) should be applied. The WURS-k as a single screening instrument cannot be recommended in alcohol dependent patients. If a higher sensitivity is desired, a combination of ADHD-SR and WURS-k is feasible.

RESUMO

Adult attention deficit/hyperactivity disorder (ADHD) often co-occurs with substance use disorders (SUD) and is associated with early onset and more severe development of SUD and with reduced treatment effectiveness. Screening tools allow for a good recognition of possible ADHD in adults with SUD and should be used routinely, followed by an ADHD diagnostic process initiated as soon as possible. Simultaneous and integrated treatment of ADHD and SUD, using a combination of pharmaco- and psychotherapy, is recommended. Long-acting methylphenidate, extended-release amphetamines, and atomoxetine with up-titration to higher dosages may be considered in patients unresponsive to standard doses. This paper includes evidence- and consensus-based recommendations developed to provide guidance in the screening, diagnosis and treatment of patients with ADHD-SUD comorbidity.

RESUMO

Rationale: Attention deficit/hyperactivity disorder (ADHD) is common in alcohol use disorder (AUD). Continuous performance tests (CPTs) allow to measure ADHD related deficits in a laboratory setting. Most studies on this topic focused on CPTs measuring inattention or impulsivity, disregarding hyperactivity as one of the core symptoms of ADHD. Methods: We examined N = 47 in three groups (ADHD N = 19; AUD N = 16; ADHD + AUD N = 12) with questionnaires on ADHD core symptoms, executive functioning (EF), mind wandering, and quality of life (QoL). N = 46 (ADHD N = 16; AUD N = 16; ADHD + AUD N = 14) were examined with a CPT (QbTest®) that also measures motor activity objectively. Results: Inattention and impulsivity were significantly increased in AUD vs. ADHD and in AUD vs. ADHD + AUD. Hyperactivity was significantly higher in ADHD + AUD vs. ADHD and ADHD + AUD vs. AUD, but not in ADHD vs. AUD. EF was lower in both ADHD groups vs. AUD. Mind wandering was increased in both ADHD groups vs. AUD. QoL was significantly lower in ADHD + AUD compared to AUD. In contrast, results of the QbTest were not significantly different between groups. Conclusion: Questionnaires are more useful in assessing ADHD core symptoms than the QbTest®. Hyperactivity appears to be a relevant symptom in ADHD + AUD, suggesting a possible pathway from ADHD to AUD. The lower QoL in ADHD + AUD emphasizes the need for routine screening, diagnostic procedures and treatment strategies for this patient group.

RESUMO

Treatment resistance in alcohol use disorders (AUD) is a major problem for affected individuals and for society. In the search of new treatment options, few case studies using deep brain stimulation (DBS) of the nucleus accumbens have indicated positive effects in AUD. Here we report a double-blind randomized controlled trial comparing active DBS ("DBS-EARLY ON") against sham stimulation ("DBS-LATE ON") over 6 months in n = 12 AUD inpatients. This 6-month blind phase was followed by a 12-month unblinded period in which all patients received active DBS. Continuous abstinence (primary outcome), alcohol use, alcohol craving, depressiveness, anxiety, anhedonia and quality of life served as outcome parameters. The primary intention-to-treat analysis, comparing continuous abstinence between treatment groups, did not yield statistically significant results, most likely due to the restricted number of participants. In light of the resulting limited statistical power, there is the question of whether DBS effects on secondary outcomes can nonetheless be interpreted as indicative of an therapeutic effect. Analyses of secondary outcomes provide evidence for this, demonstrating a significantly higher proportion of abstinent days, lower alcohol craving and anhedonia in the DBS-EARLY ON group 6 months after randomization. Exploratory responder analyses indicated that patients with high baseline alcohol craving, depressiveness and anhedonia responded to DBS. The results of this first randomized controlled trial are suggestive of beneficial effects of DBS in treatment-resistant AUD and encourage a replication in larger samples.

RESUMO

Despite a growing literature on the complex bidirectional relationship of ADHD and substance use, reviews specifically focusing on alcohol are scarce. ADHD and AUD show a significant genetic overlap, including genes involved in gluatamatergic and catecholaminergic neurotransmission. ADHD drives risky behavior and negative experiences throughout the lifespan that subsequently enhance a genetically increased risk for Alcohol Use Disorders (AUD). Impulsive decisions and a maladaptive reward system make individuals with ADHD vulnerable for alcohol use and up to 43 % develop an AUD; in adults with AUD, ADHD occurs in about 20 %, but is vastly under-recognized and under-treated. Thus, routine screening and treatment procedures need to be implemented in AUD treatment. Long-acting stimulants or non-stimulants can be used to treat ADHD in individuals with AUD. However, it is crucial to combine medical treatment for ADHD with pharmacotherapy and psychotherapy for AUD, and other comorbid disorders. Identification of individuals at risk for AUD, especially those with ADHD and conduct disorder or oppositional defiant disorder, is a key factor to prevent negative outcomes.

RESUMO

Rationale: Both attention deficit-/hyperactivity disorder (ADHD) and alcohol use disorder (AUD) are accompanied by deficits in response inhibition. Furthermore, the prevalence of comorbidity of ADHD and AUD is high. However, there is a lack of research on whether the same neuronal subprocesses of inhibition (i.e., interference inhibition, action withholding and action cancellation) exhibit deficits in both psychiatric disorders. Methods: We examined these three neural subprocesses of response inhibition in patient groups and healthy controls: non-medicated individuals with ADHD (ADHD; N = 16), recently detoxified and abstinent individuals with alcohol use disorder (AUD; N = 15), and healthy controls (HC; N = 15). A hybrid response inhibition task covering interference inhibition, action withholding, and action cancellation was applied using a 3T functional magnetic resonance imaging (fMRI). Results: Individuals with ADHD showed an overall stronger hypoactivation in attention related brain areas compared to AUD or HC during action withholding. Further, this hypoactivation was more accentuated during action cancellation. Individuals with AUD recruited a broader network, including the striatum, compared to HC during action withholding. During action cancellation, however, they showed hypoactivation in motor regions. Additionally, specific neural activation profiles regarding group and subprocess became apparent. Conclusions: Even though deficits in response inhibition are related to both ADHD and AUD, neural activation and recruited networks during response inhibition differ regarding both neuronal subprocesses and examined groups. While a replication of this study is needed in a larger sample, the results suggest that tasks have to be carefully selected when examining neural activation patterns of response inhibition either in research on various psychiatric disorders or transdiagnostic questions.

RESUMO

Objective: ADHD is common in patients with alcohol dependence, but prevalence results are inconsistent. We investigated ADHD prevalence in a complex design to avoid over- or underdiagnosing. Method: Patients with alcohol dependence starting long-term residential treatment were included. A structured interview (Diagnostic Interview for ADHD in Adults [DIVA]) was conducted on all patients. DIVA results indicating childhood or adulthood ADHD were assessed in successive diagnostic interviews by two expert clinicians. Results: 415 of 488 patients had completed the entire diagnostic assessment. ADHD prevalence was 20.5%. DIVA results correlated moderately with experts' diagnoses. In patients with ADHD, a higher comorbid illicit substance use was prevalent and alcohol dependence started earlier and was more severe. Conclusion: This study provides the largest sample on ADHD prevalence in alcohol dependent inpatients. Despite great efforts to avoid overestimation, we found every fifth patient to have ADHD. ADHD diagnosis should not be based solely on a structured interview but should be clinically confirmed.

RESUMO

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a common comorbid disorder that is frequently overlooked in adults with alcohol use disorder (AUD). Moreover, identifying ADHD in AUD patients is time-consuming and difficult. The aim of this study was to assess the clinical utility of two self-report screening instruments for adult ADHD in AUD patients. METHODS: 404 adults seeking residential treatment for AUD were screened using the Conners' Adult ADHD Rating Scale Screening Self-Rating (CAARS-S-SR) and the Adult ADHD Rating Scale (ASRS). Results were compared with ADHD diagnosis obtained from a stepped approach: first, a structured interview (Diagnostic Interview for ADHD in adults 2.0.; DIVA) was applied; second, probable ADHD diagnoses had to be confirmed by two expert clinicians. RESULTS: At the previously reported cut-off values, ASRS and CAARS-S-SR showed low sensitivities of 57.1 and 70.6%. A high number of false negative results (NPV ASRS: 89.5%; CAARS-S-SR: 92.3%) indicates underreporting of ADHD symptoms. Sensitivity improved at lower cut-off (ASRS ≥ 11; CAARS-S-SR ≥60) or with a combination of both instruments at lower cut-offs. Area Under the Curve (AUC) for the combination of ASRS and CAARS-S-SR was superior to the AUCs of the single questionnaires. CONCLUSIONS: Underreporting of ADHD symptoms in ASRS and CAARS-S-SR of AUD patients requires lower cut-off values to detect the majority of ADHD, albeit at the expense of an increased rate of false-positive results. Cut-off values should be adjusted to the clinical setting. Clinicians should take into consideration that a negative screening result does not necessarily imply absence of ADHD.

RESUMO

ADAM10 is a metalloproteinase acting on the amyloid precursor protein (APP) as an alpha-secretase in neurons. Its enzymatic activity results in secretion of a neuroprotective APP cleavage product (sAPP-alpha) and prevents formation of the amyloidogenic A-beta peptides, major hallmarks of Alzheimer's disease (AD). Elevated ADAM10 levels appeared to contribute to attenuation of A-beta-plaque formation and learning and memory deficits in AD mouse models. Therefore, it has been assumed that ADAM10 might represent a valuable target in AD therapy. Here we screened a FDA-approved drug library and identified disulfiram as a novel ADAM10 gene expression enhancer. Disulfiram increased ADAM10 production as well as sAPP-alpha in SH-SY5Y human neuronal cells and additionally prevented A-beta aggregation in an in vitro assay in a dose-dependent fashion. In addition, acute disulfiram treatment of Alzheimer model mice induced ADAM10 expression in peripheral blood cells, reduced plaque-burden in the dentate gyrus and ameliorated behavioral deficits. Alcohol-dependent patients are subjected to disulfiram-treatment to discourage alcohol-consumption. In such patients, enhancement of ADAM10 by disulfiram-treatment was demonstrated in peripheral blood cells. Our data suggest that disulfiram could be repurposed as an ADAM10 enhancer and AD therapeutic. However, efficacy and safety has to be analyzed in Alzheimer patients in the future.
