概括
多巴胺受体D1 (DRD1) 基因影响了戒断期间酒精渴望的严重程度. 特定的DRD1单核酸多态 (SNP) 与渴望增加有关,可能引导个性化酒精使用障碍治疗.
科学领域:
- 神经遗传学 神经遗传学
- 成精神病学成精神病学
背景情况:
- 酒精使用障碍 (AUD) 是一种慢性复发性疾病,其中渴望是复发的关键因素.
- 之前的横截面研究没有发现多巴胺受体D1 (DRD1) 基因单核酸多态 (SNPs) 与渴望严重程度之间的关联.
- 在戒断期间,渴望的严重程度可能会发生变化,因此需要进行纵向研究以了解其动态.
研究的目的:
- 为了研究DRD1基因SNP与AUD患者在两周禁食期间的渴望动态之间的关联.
- 检查DRD1特异性SNP如何与戒酒后渴望严重程度的变化有关.
主要方法:
- 招募了221名严重AUD的台湾汉族患者和117名健康对照.
- 在基线,戒断第一周和第二周使用强迫性饮酒量表 (OCDS) 评估酒精渴望.
- 通过全基因组归算和执行SNP和单种型分析,基因型特定的DRD1SNP (rs12518222, rs4867798, rs686, rs4532, rs5326, rs265981) 进行了基因型分析.
主要成果:
- DRD1 SNPs rs12518222和rs5326与AUD有显著的相关性.
- 特定小等位基因 (rs12518222-T,rs4867798-C,rs5326-A) 和主要等位基因 (rs686-A,rs4532-T,rs265981-G) 的携带者表现出更高的戒断后渴望.
- 包含这些等位基因的特定单元型 (TCATTG) 与更严重的渴望有关.
结论:
- 在患有AUD的个体中,DRD1基因在戒断后阶段调节渴望变化的作用.
- 与更强的渴望相关的已识别的DRD1SNP可能作为复发风险的生物标志物.
- 研究结果支持开发个性化治疗策略,以改善AUD的渴望管理.

Drug Abuse and Addiction: Pharmacological Phenomena
1.1K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Drug Dependence

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Substance Use Disorders Affecting Sleep
400
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

CNS Depressants: Alcohol and Nicotine
1.0K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
