BACKGROUND The neuropeptides leptin and ghrelin are involved in the appetite regulating network consisting of distinct orexigenic (ghrelin) and anorexigenic (leptin) circuitries. Recently, it has been shown that elevated leptin levels are associated with alcohol craving in patients suffering from alcoholism. Therefore, the aim of the present pilot study was(More)
BACKGROUND Alpha synuclein has been found elevated in dopamine neurons of cocaine abusers and in rats whose alcohol preference is inbred. METHODS The alpha synuclein mRNA expression level was measured by quantitative polymerase chain reaction in the blood of 75 male alcoholics and 69 nondrinking healthy control subjects. Alcohol craving was assessed by(More)
Preclinical study results suggest that brain-derived neurotrophic factor (BDNF) and glial cell line-derived neurotrophic factor (GDNF) modulate addictive behaviour. Therefore we investigated alterations in BDNF (81 male patients) and GDNF serum levels (52 male patients) in alcohol-dependent patients during alcohol withdrawal (day 1, 7 and 14) in comparison(More)
BACKGROUND A role of appetite-regulating peptides like leptin and ghrelin in the neurobiology of alcohol craving has been proposed by several studies. Aim of this analysis was to search for differences regarding an association between these peptides and alcohol craving with respect to different subtypes and beverage consumption patterns in patients with(More)
BACKGROUND Alpha synuclein has been found to be increased in dopamine neurones of cocaine abusers and in rats whose alcohol preference is inbred. Furthermore, increased alpha-synuclein messenger RNA expression has been linked to craving in patients with alcoholism. The aim of the current study was to investigate whether protein levels of alpha synuclein in(More)
Recent studies have described an association of leptin serum levels and craving in alcohol dependent patients. The aim of the present study was to investigate a large patients' sample using a power-based statistical analysis. We included 156 male and 33 female patients suffering from alcohol dependence admitted for detoxification treatment. Leptin serum(More)
The level of epigenetic DNA methylation is an important factor in the pathogenesis of various human diseases. As smoking may influence DNA methylation, we investigated the effect of smoking habits on global DNA methylation in 298 genomic DNA samples (73 fathers, 69 mothers and 156 offspring). We did not find a direct effect of smoking on global DNA(More)
OBJECTIVE There is growing evidence, that genetic variants contribute to the pathogenesis of anorexia nervosa and bulimia nervosa. Genetic studies have revealed candidate genes, but no satisfactory associations with the disorders have been found so far. The aim of the present study was to evaluate, whether behavioral and attitudinal traits of the disorders(More)
AIMS To investigate a possible association of nicotine dependence and alcohol craving. DESIGN A prospective cross-sectional study on patients diagnosed with alcohol dependence. SETTING Detoxification unit of a regional psychiatric hospital. PARTICIPANTS A total of 127 smoking male patients were included in the study at admission for detoxification(More)
Gray matter abnormalities have been found in anorexia nervosa (AN) in several brain regions. However, little is known about white matter abnormalities under the condition of AN. To comprehensively assess the microstructural integrity of white matter pathways in women with anorexia nervosa, we performed voxel-based Diffusion Tensor Imaging (DTI). 21 women(More)
