Schizophrenia is associated with a high preva- lence of cigarette-smoking and abnormal lipid profiles. The purpose of this study was to determine whether the profiles differ between schizophrenic smokers and non-smokers and whether the lipid profiles are related to psychopathological symptoms. Serum lipid profiles were measured in 130 male inpatients with DSM-IV-defined schizophrenia： 104 smokers and 26 non-smokers. Symptoms were assessed using the Positive and Negative Syndrome Scale （PANSS）. Our results showed that positive PANSS symp- toms were fewer in smokers than in non-smokers, while the negative symptoms were fewer in those who smoked more cigarettes. Total protein and globulin levels were significantly lower in the smokers than in the non-smokers. However, there was no significant difference in total cholesterol, triglycerides, high-density lipoprotein choles terol （HDL-c）, low-density lipoprotein cholesterol, apolipoprotein A1, or apolipoprotein B between the smokers and non-smokers. However, the PANSS positive subscale had a significant negative correlation with the HDL-c levels （a protective factor） in the smokers but not in the non-smokers. Our findings suggest that schizophrenic patients who smoke have fewer psychotic symptoms, but contrary to expectation, smoking does not alter lipid profile levels.

Pharmacogenetic Treatments for Alcohol and Stimulants

Pharmacogenetic Treatments for Alcohol and Stimulants

Pharmacogenetics uses genetic tests to predict the effectiveness of medication treatments for individual patients with drug dependence such as alcohol and opiates. An important shared neurobiological component of the reinforcement and dependence on alcohol and opiates is alcohol’s enhancement of β- endorphin release. The physiological and subjective effects of both alcohol and opiates are associated with β-endorphin and the mu opiate system. A pharmacotherapy that has been effective for both disorders is naltrexone, which increases baseline β-endorphin release blocking further release by alcohol. Naltrexone’s action as an alcohol pharmacotherapy is facilitated by a putative functional single nucleotide polymorphism (SNP) in the opioid mu receptor gene (Al18G) which alters its receptor function. Patients with this SNP have significantly lower relapse rates to alcoholism when treated with naltrexone. This SNP is particularly common among northern Chinese suggesting an important role for naltrexone treatment of alcoholism in China. Another important genetic polymorphism related to stimulant and perhaps other types of dependence frequently occurs (about 40% of the population) in the promoter region of the gene coding for dopamine beta hydroxylase (DβH). This polymorphism leads to 10 to 100 times lower levels of the DβH enzyme, which converts dopamine to norepinephrine in neurons. Stimulant abusers with normal levels of this enzyme show significant reductions in stimulant abuse when treated with DβH inhibitors, while those with the polymorphism for low DβH levels show no treatment efficacy with these medications. Pharmacogenetics has great potential for improving treatment outcome as we identify gene variants that affect pharmacodynamic as well as the more commonly studied pharmacokinetic factors. These mutations can guide pharmacotherapeutic agent choice for optimum treatment of alcohol and stimulant abuse and reduce relapse after successful initial abstinence.

遗传药理学使用基因检测的方法预测药物治疗对酒精或阿片类物质依赖患者个体的有效性。酒精和阿片类物质产生强化效应和依赖的共同神经生物学基础是增加β-内啡肽释放。酒精和阿片类物质引起的生理和主观效应都与β-内啡肽和μ阿片受体有密切的关系。纳曲酮治疗是一种对酒精和阿片依赖均有效的治疗方法,其能增加β-内啡肽的基础释放量,从而抑制酒精引起的β-内啡肽进一步释放。纳曲酮在治疗酒精依赖中的作用被认为与μ阿片受体基因(Al18G)的功能性单核苷酸多态性(SNP)有关。具有这种单核苷酸多态性的酒精依赖患者使用纳曲酮治疗后复发率低。这种单核苷酸多态性在中国北方人中较为常见,因此提示了纳曲酮治疗酒精依赖在中国的重要性。另一个与精神活性物质或其他药物依赖相关的重要基因多态性多发生于编码多巴胺β-羟化酶(DβH)基因的启动子区域。这种基因多态性可导致多巴胺β-羟化酶水平降低10 -100倍,使神经元中的多巴胺转化为去甲肾上腺素。多巴胺β-羟化酶水平正常的精神活性物质依赖患者采用多巴胺β-羟化酶抑制剂治疗能明显减少药物滥用,而多巴胺β-羟化酶水平低的患者采用该疗法治疗无效。遗传药理学在改善治疗效果方面有巨大的潜力。我们已经鉴别出能影响药效学和药代动力学因素的基因变异体。这些变异能够指导药物治疗的选择,使酒精和精神活性物质滥用患者得到最优化的治疗,降低戒断后的复吸率。
