住院精神分裂症并发糖尿病患者与抗精神病药物应用的关系分析 总被引:3,自引:0,他引:3
目的探索抗精神病药物与精神分裂症伴发糖尿病的临床关系。方法观察445例住院精神分裂症患,将氯丙嗪、氯氮平、利培酮及氯氮平合并氯丙嗪分组比较,研究药物种类、住院治疗时间对血糖的影响程度。结果血糖增高和糖尿病的发生率分别为19.78%和12.13%,都以氯氮平合并氯丙嗪组最高,氯氮平次之;氯丙嗪组、氯氮平组及氯氮平合并氯丙嗪组末次血糖浓度明显高于首次血糖浓度。除利培酮组外,住院治疗1~10年的血糖浓度明显增高,但10年后氯氮平组仍有增高趋势。结论氯氮平合并氯丙嗪对血糖代谢影响最大,氯氮平具有更长远的不利影响,使用抗精神病药物时应定期监测血糖。 相似文献

抗精神病药与精神分裂症认知功能 总被引:2,自引:0,他引:2
本文综述了精神分裂症存在的主要认知缺陷,测试方法和抗精神病药对精神分裂症认知功能的影响。认知功能缺陷是克雷丕林所描述精神分裂症的核心特征,且不能由精神症状等精神病理学解释。精神分裂症的认知缺陷主要包括注意障碍、记忆障碍、抽象思维障碍和信息整合障碍4个方面。注意障碍包括听觉和视觉注意障碍,是引起病人信息加工困难的主要原因。注意障碍又可分注意分散和监控性注意障碍,注意专注和转移困难,选择性注意障碍和警觉性降低。记忆障碍一般是广泛性的,涉及记忆系统的各个部分。精神分裂症的记忆缺陷可表现为故事的复述,言… 相似文献

Caveolin-1 (Cav-1) is a scaffolding protein important for regulating receptor signaling cascades by partitioning signaling molecules into membrane microdomains. Disruption of the CAV1 gene has recently been identified as a rare structural variant associated with schizophrenia. Although Cav-1 knockout (KO) mice displayed no baseline behavioral disruptions, Cav-1 KO mice, similar to schizophrenic individuals, exhibited increased sensitivity to the psychotomimetic N-methyl--aspartate receptor antagonist phencyclidine (PCP). Thus, PCP disruption of prepulse inhibition (PPI) and PCP-induced mouse locomotor activity were both enhanced by genetic deletion of Cav-1. Interestingly, genetic deletion of Cav-1 rendered the atypical antipsychotics clozapine and olanzapine and the 5-HT2A-selective antagonist M100907 ineffective at normalizing PCP-induced disruption of PPI. We also discovered that genetic deletion of Cav-1 attenuated 5-HT2A-induced c-Fos and egr-1 expression in mouse frontal cortex and also reduced 5-HT2A-mediated Ca2+ mobilization in primary cortical neuronal cultures. The behavioral effects of the 5-HT2A agonist (2,5-dimethoxy-4-iodoamphetamine) including head twitch responses and disruption of PPI were also attenuated by genetic deletion of Cav-1, indicating that Cav-1 is required for both inverse agonist (that is, atypical antipsychotic drug) and agonist actions at 5-HT2A receptors. This study demonstrates that disruption of the CAV1 gene—a rare structural variant associated with schizophrenia—is not only pro-psychotic but also attenuates atypical antipsychotic drug actions. 相似文献

BACKGROUND: Previous correlational research with schizophrenic patients has suggested that the second-generation antipsychotic medication clozapine helps to induce remissions of substance use disorder in patients with co-occurring psychosis and substance abuse. This research, however, could be biased by selection factors. Studying patients who are currently in substance abuse remission could control for level of motivation to stop using substances and other methodological confounds. METHODS: To test whether clozapine was associated with prevention of substance abuse relapses, we examined patients with schizophrenia or schizoaffective disorder who were in their first 6-month remission of substance use disorder during a prospective 10-year follow-up study. All patients received yearly multimodal assessments of substance use. Antipsychotic medications were prescribed by community doctors as part of usual clinical care. RESULTS: Patients using clozapine at the first 6-month period of substance abuse remission (n = 25) were much less likely to relapse over the next year compared with those on other antipsychotic medications (n = 70): 8.0% vs 40.0%, chi(2) = 8.73 (df = 1), P = .003. Although medication assignment was not randomized, several potential confounders were similar between the groups. CONCLUSION: Clozapine should be considered for the treatment of patients with schizophrenia and co-occurring substance use disorder to prevent relapses to substance abuse. 相似文献

OBJECTIVE: Schizophrenic patients who are only partially responsive to clozapine pose a therapeutic challenge. In these circumstances some clinicians would consider adding in a second antipsychotic. We present a case report and review evidence for the efficacy of such augmentation strategies. METHOD: Single case report and literature review. RESULTS: The total number of patients in studies and case reports of combining clozapine with other antipsychotics is small. There has been only one randomized controlled trial. This found the addition of sulpiride to clozapine resulted in clinical improvement in some patients. CONCLUSION: Further randomized controlled studies of augmentation of clozapine therapy are needed to provide scientific justification for this clinical practice. 相似文献

In this research we investigated the effects of 4 antipsychotic drugs with different anticholinergic components on different memory functions of schizophrenic patients. Drugs were administered in cumulative doses and memory was tested 90 min after each drug was administered. The results show that chlorpromazine and thioridazine impaired short-term verbal memory after 6 h of sequential administration. Trifluoperazine and haloperidol improved short-term verbal memory from the third to the fifth administration. Immediate memory, long-term memory and visual short-term memory were not impaired by any drug. 相似文献

In this commentary, we review recent research suggesting that (a) second-generation antipsychotics (SGAs) may be no more effective than first-generation antipsychotics (FGAs), (b) the reduced risk of EPS and tardive dyskinesia with SGAs is more weakly supported by the research literature than has been appreciated, and (c) benefits may be offset by greater metabolic risks of some SGAs and their substantially greater cost. Bearing in mind, as well, that risperidone, currently the least expensive SGA, will soon be available as an even less expensive generic drug, we propose a new algorithm for maintenance antipsychotic therapy. We further outline a cautious implementation procedure that relies on standardized documentation and feedback, without a restrictive formulary that would limit physician choice. The algorithm outlined here and the process for its implementation are intended as a stimulus for discussion of potential policy responses, not as a finalized proposition. 相似文献
