<b><i>Background:</i></b> Atrial natriuretic peptide (ANP) is well known in psychiatric disorders to modulate hypothalamic-pituitary-adrenal axis activity. Disturbances of ANP have been described in early abstinent alcohol-dependent patients. This is the first longitudinal investigation on cytosine-phosphatidyl-guanine (CpG)-island promoter methylation of the <i>ANP</i> gene in the blood of tobacco-dependent patients. <b><i>Methods:</i></b> In a longitudinal approach, we investigated whether changes in ANP serum levels correlated to CpG methylation of the respective gene promoters on days 1, 7, and 14 of tobacco withdrawal. <b><i>Results</i></b> <b><i>and Conclusion:</i></b> Compared to non-smokers, promoter-related deoxyribonucleic acid methylation of the ANP promoter was significantly elevated on days 7 and 14 of withdrawal in tobacco-dependent patients. Baseline methylation status of the ANP promoter was not significantly different from controls, arguing for an impaired regulation during withdrawal.

Zusammenfassung. Ziel der Studie: Untersucht wurden die Einstellungen gegenüber Menschen mit Alkoholabhängigkeit und die Akzeptanz neurobiologischer sowie sozialer Krankheitsursachen. Methodik: Mit einem 75-Item Fragebogen wurden die Ansichten von 254 Teilnehmern erfragt und die Einstellungen gegenüber alkoholabhängigen Patienten von Betroffenen und gesunden Menschen verglichen. Die betroffenen alkoholabhängigen Patienten (n = 122) wurden während einer stationären qualifizierten Entzugsbehandlung befragt, nachdem der körperliche Entzug vorüber war. In den Vergleichsgruppen wurden medizinisches Personal (n = 70) sowie Studierende (n = 62) ohne medizinisches Hintergrundwissen befragt. Ergebnisse: Zwischen den Betroffenen und dem medizinischen Personal fanden wir keine Unterschiede bezüglich der Zuschreibung neurobiologischer Faktoren als Ursachen der Alkoholabhängigkeit. Studierende hielten neurobiologische Faktoren für weniger ursächlich für Alkoholabhängigkeit als Betroffenen und als medizinisches Personal. Bezüglich der sozialen Faktoren als Ursachen der Alkoholabhängigkeit ergaben sich keine signifikanten Unterschiede zwischen den drei Gruppen. Die Betroffenen bewerteten die Charaktereigenschaften alkoholabhängiger Patienten insgesamt positiver als das medizinische Personal und die Studierenden.Schlussfolgerung: Betroffene berichten positivere Einstellungen gegenüber Menschen die an einer Alkoholabhängigkeit leiden, als medizinisches Personal und als Studierende.

<b><i>Introduction:</i></b> Preclinical studies have shown that calcium seems to be the active component of the anti-craving drug acamprosate (Ca²⁺ bis-acetyl-homotaurinate). Clinical effects in humans have also indicated an association between increased calcium plasma concentration due to acamprosate treatment and better outcome relating to time to relapse and cumulative abstinence. In contrast, low calcium concentration in alcohol-dependent patients was related with craving for alcohol. The main goal of the trial was to investigate whether an oral calcium administration is able to affect craving, withdrawal, and relapse risk in alcohol-dependent patients. <b><i>Methods:</i></b> We conducted a single-blind, randomized, monocentric, controlled clinical two-arm trial in alcohol-dependent patients (Clinical Trials Registration: DRKS00011293). A total of 55 alcohol-dependent subjects received calcium carbonate (800 mg + 5 μg vitamin D) versus sodium bicarbonate (1,000 mg) daily during the 14 days of inpatient alcohol-withdrawal treatment. <b><i>Results:</i></b> Based on an intention-to-treat protocol, withdrawal intensity (assessed with CIWA-Ar) in the calcium carbonate group attenuated faster than in the sodium bicarbonate subgroup. Alcohol craving (assessed with OCDS) in the calcium carbonate subgroup was also significantly reduced versus the sodium bicarbonate subgroup. <b><i>Conclusion:</i></b> Our data support earlier findings and show that treatment with calcium carbonate during alcohol withdrawal reduces symptoms of alcohol withdrawal as well as alcohol craving in a controlled clinical pilot study. Mode of actions will need to be determined to allow the further development of pharmacological interventions beyond Ca²⁺ bis-acetyl-homotaurinate.

Background: Borderline personality disorder (BPD) is one of the most common personality disorders among persons with substance use disorders (SUDs) and is characterized by severe clinical symptoms. The aim of this study was to investigate if the effect of dialectical behavior therapy for substance use disorders (DBT-S) inpatient treatment on psychopathological symptom load in patients suffering from both BPD and SUD can be augmented by weekly 60-min "Trauma Informed Hatha Yoga" sessions. Materials and Methods: Thirty-nine patients suffering from comorbid BPD and SUD were consecutively in time included in this quasi-experimental pilot study (first intervention then control group). In the intervention group, weekly Trauma Informed Hatha Yoga sessions were added to standard DBT-S for 8 weeks. The participants of the control group received standard DBT-S. All participants completed several self-report questionnaires to assess symptoms of depression, anxiety, symptoms of BPD, and their subjective stress perception at three points in time during the study course. Results: A repeated measures analysis of variance with patients' psychopharmacological medication as covariate revealed a significant main effect of time for each of the psychometric scales (State and Trait Anxiety Inventory subscale for state anxiety [STAI-S] p = 0.001, Beck Depression Inventory [BDI] p < 0.001; Borderline Symptom List 23 [BSL] p = 0.036) indicating that the psychopathological symptom load of the patients was significantly lower at the end of the DBT-S therapy compared to the beginning in both study groups. Moreover, there was a significant interaction effect of group*time on the psychometric scales STAI-T (subscale for trait anxiety) sum score (p = 0.010) and the sum score of the Perceived Stress Scale (PSS) (p = 0.043). This was expressed by the fact that the participants of the intervention group showed a significant reduction of the STAI-T sum score as well as the sum score of the Perceived Stress Scale (PSS), while the control group did not. Due to the exploratory nature of this study, correction for multiple testing was omitted. Conclusion: Although they are very preliminary, our results suggest that practicing Trauma Informed Hatha Yoga on a regular basis in addition to DBT-S inpatient treatment seems to reduce the level of trait anxiety and perceived stress significantly more than DBT-S inpatient treatment alone. Nevertheless, the effectiveness of Trauma Informed Hatha Yoga in reducing trait anxiety and perceived stress in patients suffering from SUD und BPD must be tested in large randomized controlled trials.

<b><i>Aims:</i></b> The nerve growth factor (NGF) and the vascular endothelial growth factor-A (VEGF-A) may be of importance for psychiatric diseases including substance use disorders. The aim of the study was to identify differences in the regulation of both neuropeptides via the DNA-methylation status of the promotor regions of NGF and VEGF-A in different forms of maintenance therapy for opioid dependence and the related stress regulation via the hypothalamic-pituitary-adrenal axis. <b><i>Methods:</i></b> We compared methylation levels of opioid-dependent patients receiving treatment with diamorphine (<i>n</i> = 28) or levomethadone (<i>n</i> = 54) and similar levels in a healthy control group (<i>n</i> = 72). <b><i>Results:</i></b> There was a significantly higher methylation of VEGF-A in opioid-maintained patients with levomethadone compared to that in the control group (estimated marginal means [EMM] [SE]): 0.036 [0.003] vs. 0.020 [0.003]; <i>p</i> &#x3c; 0.001). We performed a cluster analysis for NGF, splitting up the results in 4 clusters. We found significant changes in methylation rates of the opioid-maintained patients compared to the controls in cluster I ([EMM] [SE]: 0.064 [0.005] vs. 0.084 [0.006]; <i>p</i> = 0.03), cluster II ([EMM] [SE]: 0.133 [0.013] vs. 0.187 [0.014]; <i>p</i> &#x3c; 0.001) and cluster III ([EMM] [SE]: 0.190 [0.014] vs. 0.128 [0.016]; <i>p</i> &#x3c; 0.001). <b><i>Conclusions:</i></b> The results are of importance, as they indicate that long-term changes in stress regulation regulated by neurotrophines are a crucial part of the symptomatology of opioid dependence, thus influencing drug consumption and the different forms of opioid-maintenance therapies.
