Aims: The present study investigated platelet monoamine oxidase-B (MAO-B) activity in male alcohol-dependent subjects in sustained full remission (minimum 1 year), to exclude possible transient changes in platelet MAO-B activity, which occur up to several months after the end of alcohol intake.

Methods: MAO-B activity was examined in 16 alcohol-dependent subjects, characterized as type 1 alcoholics, with an abstinence period of 6 +/- 7 years (mean +/- SD) and in 12 healthy controls.

Results: The long-term abstinent alcohol-dependent subjects did not differ from controls in platelet MAO-B activity.

Conclusions: Type 1 male alcohol-dependent subjects appear to have normal platelet MAO-B activity. The possibility, however, cannot be excluded that type 2 long-term abstinent alcoholics may have lower platelet MAO-B activity.

Article Synopsis
  • Alcohol dependence (AD) and sleep disturbance (SD) both negatively impact gut microbiota, but the interaction between SD and gut flora in AD patients is not well understood.
  • This study involved 32 AD patients and 20 healthy controls, analyzing fecal samples throughout the day to explore differences in gut microbiota between AD patients with poor sleep (ADwPS) and good sleep (ADwGS).
  • Results showed significant differences in gut microbiota composition and diurnal patterns, with the ADwPS group exhibiting higher anxiety, depression, and greater fluctuation in pathogenic bacteria compared to the ADwGS group.

Background: Acute gamma-aminobutyric acid (GABAergic) effects of alcohol consumption are well-known, whereas prior research has yielded inconsistent findings regarding on adaptations of the GABAergic neurotransmitter system to chronic alcohol use. Previous studies indicate either elevated or reduced GABA levels in cortical regions such as the anterior cingulate cortex (ACC) in persons with alcohol use disorder (AUD). We tested the hypothesis that active alcohol consumption compared to abstinence contributes to GABA levels as observed in prior research on chronic alcohol use.

Introduction Post-pandemic alcohol consumption is on the rise due to people starting to adapt themselves to the practice of consuming alcoholic beverages at home. In addition to the direct effects of intoxication and addiction, estimates suggest that alcohol contributes to approximately 20-30% of global cases of oesophagal cancer, liver cancer, cirrhosis of the liver, homicide, epilepsy, and motor vehicle accidents. In India, one-fifth of alcohol consumers were found to be alcohol dependent.

Genetic features of alcohol dependence have been extensively investigated in recent years. A large body of studies has underlined the important role of genetic variants not only in metabolic pathways but also in the neurobiology of alcohol dependence, mediated by the neuronal circuits regulating reward and craving. Serotonin transporter (5-HTT), encoded by the SLC6A4 gene (Solute carrier family 6-neurotransmitter transporter-member 4), is targeted by antidepressant drugs such as selective serotonin reuptake inhibitors (SSRIs) and plays a pivotal role in serotoninergic transmission; it has been associated with psychiatric diseases and alcohol dependence.

Background: The negative impact of Paternal Alcohol Use Disorder (PAUD) on children's psychosocial well-being is an overlooked issue that warrants more global research attention. Alcohol dependence is often seen as a hidden problem with subtle yet harmful effects, especially on the children of those with alcohol dependence. These children often remain invisible due to their loyalty and unwillingness to disclose their dysfunctional family situation.
