导言:滥用甲基苯丙胺等兴奋剂是一个全球性的公共卫生问题。甲基苯丙胺使用障碍的一个重要神经化学机制可能是多巴胺能神经传递的改变。例如,以前使用正电子发射断层扫描(PET)的研究一直表明,纹状体多巴胺D2型受体的可用性(定量为结合潜力; BPND)在甲基苯丙胺使用障碍中较低。此外,已知甲基苯丙胺的使用通过多种生理途径诱导慢性神经炎症。因此,D2型受体的上调和/或神经炎症的减弱可以为这种疾病提供治疗效果。体外研究表明,阻断腺苷2A(A2 A)受体可以防止D2受体下调和神经炎症相关的脑损伤。然而,目前还没有研究对这一假设进行检验。 方法和分析:使用受试者内设计,本试验将评估选择性A2 A受体拮抗剂istradefylline主要对纹状体D2型BPND的影响,其次是对甲基苯丙胺使用障碍个体全脑神经炎症的影响。研究假设是,istradefylline将增加纹状体D2型BPND和减轻神经炎症。将招募20名患有甲基苯丙胺使用障碍的受试者(年龄20-65岁),在40 mg/天的伊司特福林给药前和给药后各接受一次[11 C]雷氯必利PET(针对每名受试者)和[11 C] DAA 1106 PET(如适用),持续2周。将在PET扫描的同一天进行神经心理学测量。
Introduction: The misuse of stimulant drugs such as methamphetamine is a global public health issue. One important neurochemical mechanism of methamphetamine use disorder may be altered dopaminergic neurotransmission. For instance, previous studies using positron emission tomography (PET) have consistently shown that striatal dopamine D2-type receptor availability (quantified as binding potential; BPND) is lower in methamphetamine use disorder. Further, methamphetamine use is known to induce chronic neuroinflammation through multiple physiological pathways. Upregulation of D2-type receptor and/or attenuation of neuroinflammation may therefore provide a therapeutic effect for this disorder. In vitro studies have shown that blockage of adenosine 2A (A2A) receptors may prevent D2-receptor downregulation and neuroinflammation-related brain damage. However, no study has examined this hypothesis yet. Methods and Analysis: Using a within-subject design, this trial will assess the effect of the selective A2A receptor antagonist, istradefylline, primarily on D2-type BPND in the striatum, and secondarily on neuroinflammation in the whole brain in individuals with methamphetamine use disorder. The research hypotheses are that istradefylline will increase striatal D2-type BPND and attenuate neuroinflammation. Twenty participants with methamphetamine use disorder, aged 20–65, will be recruited to undergo [11C]raclopride PET (for every participant) and [11C]DAA1106 PET (if applicable) once before and once after administration of 40 mg/day istradefylline for 2 weeks. Neuropsychological measurements will be performed on the same days of the PET scans.
