Genome-wide Association Study of Alcohol Dependence
2009
Context Alcohol dependence is a serious and common public health problem. It is well established that genetic factors play a major role in the development of this disorder. Identification of genes that contribute to alcohol dependence will improve our understanding of the mechanisms that underlie this disorder. Objective To identify susceptibility genes for alcohol dependence through a genome-wide association study (GWAS) and a follow-up study in a population of German male inpatients with an early age at onset. Design The GWAS tested 524 396 single-nucleotide polymorphisms (SNPs). All SNPs with P −4 were subjected to the follow-up study. In addition, nominally significant SNPs from genes t…
Association of Low Striatal Dopamine D2Receptor Availability With Nicotine Dependence Similar to That Seen With Other Drugs of Abuse
2008
All drugs of abuse induce a phasic dopamine release within the striatum that does not undergo habituation. Prolonged substance consumption impairs the natural function of the mesolimbic dopamine system, as shown by a decrease in the availability of striatal dopamine 2 (D(2)) receptors in patients suffering from cocaine, heroin, amphetamine, and alcohol dependence. However, it is unclear whether similar changes can also be observed in heavy-smoking nicotine-dependent smokers.In vivo D(2)/D(3) receptor availability was determined with [ (18)F]fallypride positron emission tomography in 17 heavy-smoking nicotine-dependent subjects and in 21 age-matched never-smoking comparison subjects. The smo…
Reliability and validity of the form 90 interview.
2004
<i>Objective:</i> Alcohol consumption is a central variable in substance abuse research and treatment. The study reports the psychometric characteristics of the German version of the Form 90 interview for the assessment of recent alcohol consumption. <i>Method:</i> Reliability was evaluated in a test-retest study (7 days) with 30 consecutively admitted psychiatric inpatients with alcohol dependence. Validity of Form 90 was assessed with a second sample of 60 alcohol-dependent inpatients. <i>Results:</i> Form 90 demonstrated good to excellent retest reliability for the central variables of alcohol consumption. Retest reliability Pearson correlation coeffic…
Alcohol-related seizures may be associated with more severe depression, alcohol dependence syndrome, and more pronounced alcohol-related problems.
2018
Severe alcohol abuse and related medical and social functioning risks, as well as clinically significant depression, are common in patients who are admitted to hospital with alcohol-related seizures (ARS) and significantly affect the quality of life of the patient. Compared with studies involving patients with alcohol dependence, no large-scale studies with the aim of finding the prevalence and severity of depression and its most commonly affected aspects for patients with ARS have been carried out in Latvia yet. The habits and frequency of alcohol use in correlation to depression and its severity are also not known. One hundred ten patients were included in the study - 60 patients with ARS…
Norepinephrine transporter gene polymorphism is not associated with susceptibility to alcohol dependence
2002
Abnormalities in monoamine neurotransmission have been implicated in the pathogenesis of alcoholism, mood disorders and schizophrenia. Murine norepinephrine transporter gene (NET) has been mapped to a region on chromosome 8 where a quantitative trait locus for ethanol sensitivity. Therefore we tested whether norepinephrine transporter (NET) gene variants confer susceptibility to either alcohol dependence or severe alcohol withdrawal symptoms. There is a highly polymorphic silent G1287A mutation in the NET gene. In our study 157 alcoholics and 185 healthy unrelated matched control subjects were analyzed for a silent G1287A mutation. No significant differences in allele and genotype distribut…
Evidence for the importance of the human dopamine transporter gene for withdrawal symptomatology of alcoholics in a German population
2002
Two new polymorphisms in the 3' untranslated region (3'UTR) of the dopamine transporter (DAT1) gene, adjacent to the known variable number of tandem repeats (VNTR) polymorphism, have been investigated in the present population-based association study including 351 alcoholics and 336 controls. The DraI restriction site was not polymorphic in our population. The G2319A polymorphism was not significantly different with respect to genotype or allele distribution between alcoholics and controls. Subsequently, in individuals with VNTR homozygosity for the ten repeat allele, we found a higher prevalence of A/A homozygosity in patients with seizure history (P = 0.001, odds ratio (OR) = 7.913), with…
Symptom-Triggered versus Standard Chlormethiazole Treatment of Inpatient Alcohol Withdrawal: Clinical Implications from a Chart Analysis
2003
To evaluate clinical effectiveness and safety of 2 different detoxification treatment protocols, a chart analysis of hospital inpatients consecutively admitted for alcohol withdrawal during one year was undertaken. Records of 33 patients receiving symptom-triggered treatment (using a modified version of the revised Clinical Institute Withdrawal Assessment for Alcohol Scale) were compared with those of patients treated by applying a fixed-dose regimen (n = 32). Patients (45.3 ± 9.8 years, 21% female) of both groups were comparable regarding illness severity, epidemiologic parameters as well as complications during the observed treatment period. Under symptom-triggered therapy, chlormethiazol…
Activity of the adenylyl cyclase in lymphocytes of male alcoholic patients is state dependent.
1998
A decreased basal and/or stimulated activity of the G-protein/adenylyl cyclase (AC) system in peripheral blood cells has been proposed to represent a trait marker for alcoholism. However, AC activity may underlie state-dependent changes, which may impair a proper interpretation of AC activity measurements. Our study examined systematically the AC activity in peripheral lymphocytes of 73 male alcohol-dependent patients (according to DSM-IV criteria) at three different time points of measurement during the clinical course of detoxification (day 0 = at admission, while still ethanol-affected; day 2 = at the presumed peak of withdrawal symptoms; day E = after detoxification). Basal and stimulat…
Tolerability profile of thiopurines in inflammatory bowel disease: a prospective experience
2017
The occurrence of thiopurine-related adverse events (AEs) may complicate the management of patients with inflammatory bowel disease (IBD). We aimed to evaluate the tolerability of thiopurines in a current IBD setting.All consecutive patients who started a treatment with azathioprine (AZA) from January 2010 to March 2016 were entered in a prospectively maintained database, and the AEs which led to the permanent discontinuation of the drug were reported.Two hundred and fifty three patients were included. Median total follow-up was 32 months (range: 0.2-75 months). At the end of the study, AZA was discontinued in 160 patients (63.2%). The main reason leading to drug withdrawal was the occurren…
Cue exposure in alcohol dependent patients: preliminary evidence for different types of cue reactivity.
2000
Craving is considered to be an important phenomenon in addictive behaviours. However, there is still an unresolved debate on what craving for alcohol means, how it is best measured and which clinical and therapeutical consequences its presence or absence may imply. Cue reactivity paradigms have been developed to elicit craving under standardized experimental conditions. Here we present preliminary results characterizing alcohol-dependent patients with regard to subjective and psychophysiological aspects of exposure to alcohol-associated cues in a cue reactivity paradigm. Thirty-six patients fulfilling at least 5 criteria of alcohol dependence according to DSM-IV criteria were studied after …
