- 遗传学 是一个遗传学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 抗抑郁药是中度至重度抑郁症的第一线治疗方法.
- 选择正确的抗抑郁药可能是具有挑战性的,因为潜在的不良事件,包括增加自杀倾向.
- 需要个性化医疗方法来优化抗抑郁药的选择并最大限度地降低风险.
研究的目的:
- 调查多基因分数 (PGS) 在预测抗抑郁药对自杀念头差异性影响的有用性.
- 评估遗传倾向如何影响抗抑郁药治疗期间自杀念头的风险.
主要方法:
- 利用一个目标试验模拟框架与遗传和临床数据超过7000名儿童和成年人患有严重抑郁症在我们所有人研究计划.
- 对比了选择性血清素再吸收抑制剂 (SSRI) 与血清素和上腺素再吸收抑制剂 (SNRIs) 和布罗的启动.
- 分析了各种精神疾病PGS的子组效应,重点关注与自杀念头的关联.
主要成果:
- 对于注意力缺陷多动症 (ADHD) 的PGS较高的患者,在启动SSRI与布罗治疗时,自杀想法的可能性增加 (HR1.66对1.06,P-相互作用=0.01).
- 对精神分裂症PGS观察到类似的趋势,尽管在统计学上并不显著 (HR 1.52对1.17,P-相互作用=0.16).
- 在PGS中没有发现SSRI与SNRI影响的显著差异.
结论:

Human Genetics
732
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Polygenic Traits
66.6K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...

Antidepressant Drugs: MAOIs and Other Agents
372
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Antidepressant Drugs: Overview
777
Antidepressant drugs are a class of medications primarily used for treating various mood disorders, including major depression, anxiety disorders, and other related conditions. These medicines work by modulating the neurotransmitter balance within the brain, alleviating depressive symptoms. Antidepressants can be broadly categorized into several groups according to their mechanism of action and chemical structure: Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine...

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs
588
Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...

Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance
302
The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.
