Association of plasma calcium concentrations with alcohol craving: New data on potential pathways

Recently, calcium was suggested to be the active moiety of acamprosate. We examined plasma calcium concentrations in association with severity of alcohol dependence and its interaction with regulating pathways and alcohol craving in alcohol-dependent patients. 47 inpatient alcohol-dependent patients undergoing detoxification treatment underwent laboratory testing, including calcium, sodium, liver enzymes as well as serum concentrations of calcitonin, parathyroid hormone and vitamin D. The psychometric dimension of craving was analyzed with the Obsessive Compulsive Drinking Scale (OCDS). The severity of withdrawal was measured with the Alcohol Dependence Scale (ADS) and with the Alcohol Dependence Scale for high-risk sample (ADS-HR). The main findings of our investigation are: a) a negative correlation of plasma calcium concentrations with alcohol craving in different dimensions of the OCDS; b) a negative correlation of plasma calcium concentrations with breath alcohol concentration; c) lowered calcitonin concentration in the high-risk sample of alcoholics; d) lowered plasma vitamin D concentrations in all alcoholic subjects. Our study adds further support for lowered plasma calcium concentrations in patients with high alcohol intake and especially in patients with increased craving as a risk factor for relapse. Lowered calcitonin concentrations in the high-risk sample and lowered vitamin D concentrations may mediate these effects. Calcium supplementation could be a useful intervention for decreasing craving and relapse in alcohol-dependent subjects.

Tobacco smoking modulates activity in the hypothalamic‐pituitary‐adrenal (HPA) axis and is used to cope with stress, especially by females. The single nucleotide polymorphism (SNP) rs1360780, linked to FK506‐binding protein 51 (FKBP5), has been shown to affect HPA axis functioning, and has thus been suggested as a promising candidate for indicating vulnerability to stress‐related disorders. The aim of this study was to investigate the interaction between nicotine consumption and rs1360780 on cortisol plasma levels in females. A total of 296 female smokers (assessed by the Fagerström Test for Nicotine Dependence; FTND) were genotyped for the SNP rs1360780. We measured participants’ cortisol plasma concentration in blood plasma collected 3 h after standardized tobacco smoking exposure. In the 36 TT‐homozygotes, we found a significant negative correlation between the FTND sum score and cortisol plasma concentrations. Using linear regression analysis, we found that the FTND sum score accounted for 12.4% of the variance of cortisol plasma levels. This association was not detected in C‐allele carriers. Our results suggest that nicotine is an important confounder in the modulation of HPA axis activity by FKBP5. In light of these findings, future studies on FKBP5 should seek to include data on nicotine consumption as a covariate.

The impact of the appetite-regulating, orexigenic peptide ghrelin on alcohol use disorders: A systematic review of preclinical and clinical data

Anne Koopmann; Rilana Schuster; Falk Kiefer

Ghrelin, which is mainly released from the stomach, is the most important orexigenic regulator of food intake, inducing appetite, enhancing adiposity and releasing growth hormone. Besides the hypothalamus, ghrelin receptors (GHS-R1A) are also expressed in the mesolimbic dopaminergic system, which increases the possibility that ghrelin plays an important role in reward regulation for substance use disorders such as alcohol addiction, especially through activating the cholinergic-dopaminergic reward link. In this review we focus on the impact of ghrelin on the development and maintenance of alcohol addiction/dependence, alcohol consumption, alcohol craving and alcohol withdrawal, attempting to integrate preclinical and clinical studies concerning the intriguing relationship between appetite regulation, reward and alcohol addiction. Integrating the existing preclinical and clinical data on ghrelin antagonism, specifically at the GHS-R1A receptor in mesolimbic dopaminergic pathways, may reveal a new and innovative target for the treatment of alcohol dependence in the future.

P02-165 - Impact of disease concepts on attitudes towards alcohol dependent patients

Introduction Stigmatizing attitudes regarding mentally ill people are common (Rusch et al., 2010). Study result suggest that the degree of stigmatization may depend on concepts of psychiatric diseases (Crisafulli et al., 2008). Aims We aimed to investigate the impact of a sole neurobiological vs. a sole sociodynamic disease concept on the attitudes of students towards the alcohol dependent patients (Crisafulli et al., 2008). Methods 200 students were randomly assigned to read information explaining alcohol dependence sole neurobiologically/sociodynamically. Subsequently, the students completed a series of questionnaires (adapted from Crisafulli et al. (2008)) regarding their attitudes towards the alcohol dependent patients. Attitudes were compared to attitudes of students not exposed to any disease concept. Results Consistent with former study results we found increased blaming and decreased willingness to finance therapy in those students exposed to the sociodynamic explanation. Attitudes regarding blaming and harmfulness of the alcohol dependent patients were increased in the neurobiological and sociodynamic group compared to the un-exposed control group. Conclusions Information regarding possible causalities regarding the development of alcohol dependence is associated with more negative attitudes towards alcohol dependent patients in the questioned students compared to unexposed controls. This may be reasoned by the recognition of alcohol dependence as a manifestation of mental illness and the subsequent inclusion of the alcohol dependent patients in the prejudices and acts of discrimination commonly leveled against the mentally ill. Therefore, multimodal interventions rather than medicinal information seem to be necessary in order to decrease stigmatization of the alcohol dependent patients.
