系统性红斑狼疮(SLE)和其他自身免疫病的治疗/治愈问题一直困扰着医药学界。过去近40年没有一个新治疗药获得批准,不过现时在研发中的一些药物可能会有希望。然而,一家独立的市场分析公司Datamonitor的一篇最新报告提到,由于对临床试验要求存在分歧,阻碍了这些药物获准的机会,但这并不防碍医生超标签范围使用这些药物。 相似文献

类风湿性关节炎,多发性硬化,1型糖尿病和狼疮都是自身免疫疾病。这样的命名是因为免疫系统错误地把人体自己的蛋白质作为外来的入侵者识别,并开始产生攻击健康细胞和组织的抗体。估计遭受自身免疫疾病的5000万美国人的75%是妇女。妇女患上自身免疫疾病比男人高三倍。为什么?一种理论解释说:妇女比男人具有增强的免疫系统,这增强了妇女对许多类型的感染的抵抗力,但也更易受自身免疫疾病的影响。 相似文献

人体正常的免疫系统由于某种原因而出现免疫功能紊乱,导致自身免疫异常疾病,如类风湿性关节炎(RA),重症肌无力,红斑狼疮,痛风,多皮硬化症,视网膜炎等。目前治疗这类疾病主要为抑制异常并且亢进的免疫系统,治疗RA的药物有消炎镇痛和激素类的非特异性药物; 制剂和中药制剂的特异性药物。又分为一线药物和二线药物,临床上分为甾体类,非甾体类抗炎药物,症状缓解药物以及免疫抑制剂或调节剂,采用口服某些外源蛋白质,通过肠粘膜上淋巴组织,激活T细胞,释放出抑制性细胞素,降低患者病灶处的发炎细胞数,从而抑制炎症反应。目前,采用口服外源蛋白质治疗此类疾病的研究有:牛髓磷脂蛋白治疗多皮硬化症,鸡Ⅱ型胶原蛋白治疗RA,牛S抗原治疗视网膜炎,碱性髓磷脂蛋白治疗脑脊髓炎,人胰岛素治疗I型糖尿病等。口服Ⅱ型胶原蛋白治疗RA已进入临床研究,显示了明显的药效作用并具有良好的安全性。由于口服某些抗原蛋白而产生免疫耐受反应,机理明确,疗效显著,不良反应小,这类药物极有可能临床用于治疗各种自身免疫异常疾病的常用药物。 相似文献

Background: C-C chemokine receptor 2 (CCR2) antagonists belong to a group of chemokine blockers, which represent a new strategy for inflammatory diseases treatment by interfering with the complex system of chemokines and their receptors. A number of CCR2 antagonists are being developed for treatment of autoimmune diseases by different pharmaceutical and biotechnological companies. Objective: In this article the dark and the bright side of therapeutic CCR2 antagonism is discussed, with a view to its potential efficacy in various autoimmune diseases, in which clinical trials are already in progress, such as multiple sclerosis and rheumatoid arthritis. We describe different modes of possible interactions with CCR2–chemokine CC motif ligand 2 (CCL2) axis, usefulness of experimental animal models, continuing clinical trials and future perspectives of CCR2 antagonists. Methods: Until now only a few peer-reviewed articles providing data on the progress of preclinical and clinical trials with CCR2 antagonists have been published; therefore, we also present data based on preliminary reports, obtained from a number of press releases, conference communications and from the PharmaProjects database. Results/Conclusion: Although there is growing evidence for a great therapeutic potential of CCR2 blockade in autoimmune diseases, especially well documented in experimental animal models, so far clinical trials with CCR2 antagonists in humans have been moderately encouraging or even disappointing, indicating a need to further elucidate the complex system of chemokine interactions. 相似文献

Background: IL-6, a glycoprotein composed of 212 amino acids in human, has a wide range of biological activity, including regulation of immune response, support of hematopoiesis, generation of acute-phase reactions and induction of inflammation and oncogenesis. Several approaches including inhibition of IL-6 production, blockage of IL-6 binding to IL-6 receptor, blockage of IL-6/IL-6R complex binding to gp 130 and blockage of the intracytoplasmic signal through gp 130 can be used to block IL-6 functions. Objective: To summarize pre-clinical development and efficacy and safety of anti-IL-6 therapies in the treatment of inflammatory and autoimmune diseases. Methods: Journal articles found within a PubMed search and data presented in abstract form from international conferences up to May 2009 are described in this review. Results/conclusions: Tocilizumab, which blocks IL-6 binding to IL-6 receptor, used as monotherapy or in combination with methotrexate for RA therapy leads to significant clinical response and amelioration of joint damage, which is superior to methotrexate. Some adverse events such as liver function disorders, hyperlipidemia, neutropenia, diarrhea and infection are observed in clinical trials. IL-6 blockers targeting directly IL-6 rather than the IL-6 receptor and fully human monoclonal antibody targeting the IL-6 receptor are currently under development. Overall, targeting IL-6 has provided a promising approach in the management of some inflammatory and autoimmune diseases. 相似文献

血脂异常是系统性红斑狼疮患者应用糖皮质激素治疗引起的较为常见的并发症。长期大量的使用外源性糖皮质激素引起了胰岛素抵抗并且抑制了血中胆固醇的转化,从而影响了总胆固醇(TC)、总甘油三酯(TG)、低密度脂蛋白(LDL)和高密度脂蛋白(HDL)水平,造成血脂异常。随着糖皮质激素在临床上的广泛应用,系统性红斑狼疮患者的血脂异常发生率也在不断升高,该文就其研究现状及发病机制等予以综述。 相似文献

As a cellular bulk degradation and survival mechanism, autophagy is implicated in diverse biological processes. Genome-wide association studies have revealed the link between autophagy gene polymorphisms and susceptibility of autoimmune diseases including systemic lupus erythematosus (SLE) and inflammatory bowel disease (IBD), indicating that autophagy dysregulation may be involved in the development of autoimmune diseases. A series of autophagy modulators have displayed protective effects on autoimmune disease models, highlighting the emerging role of autophagy modulators in treating autoimmune diseases. This review explores the roles of autophagy in the autoimmune diseases, with emphasis on four major autoimmune diseases [SLE, rheumatoid arthritis (RA), IBD, and experimental autoimmune encephalomyelitis (EAE)]. More importantly, the therapeutic potentials of small molecular autophagy modulators (including autophagy inducers and inhibitors) on autoimmune diseases are comprehensively analyzed. 相似文献

Leflunomide modulates T-cell responses and induces a shift from the Th1 to Th2 subpopulation. This process results in a beneficial effect in diseases in which there is good evidence that T cells play a major role in both initiation and perpetuation of the inflammatory condition. Leflunomide has been successfully used for treating rheumatoid arthritis and psoriatic arthritis for many years. The active metabolite of leflunomide is teriflunomide, which has been approved for treating multiple sclerosis. Teriflunomide, just like the mother drug, inhibits dihydro-orotate dehydrogenase and synthesis of pyrimidine. The present review presents and discusses the safety profiles of leflunomide and teriflunomide, two drugs that are indeed the same, considering that much can be learned from the reported side effects of both. 相似文献

阿贝莫司钠(abetimus sodium,LJP-394)是美国La Jolla制药公司历时20多年研究开发的拟用于治疗系统性红斑狼疮的新药。阿贝莫司钠属于B细胞耐受原,可与B细胞抗dsDNA抗体交联而诱导B细胞产生免疫耐受。在Ⅲ期临床试验中,阿贝莫司钠能降低部分狼疮性肾炎患者抗dsDNA抗体水平,但对肾炎复发无明显的保护作用。因此,2009年La Jolla制药公司宣布终止了阿贝莫司钠的临床试验。本文对就阿贝莫司钠的作用特点和研究脉络作一综述,为研究开发治疗系统性红斑狼疮的新药提供借鉴。 相似文献

α4β1整合素在多发性硬化发病机制的最早环节中起关键作用,阻断α4整合素可防止自身免疫细胞通过与中枢神经的微血管粘附而进入中枢神经系统,从而减轻炎症性脱髓鞘反应。那他珠单抗是针对整合素的α4亚单位的单克隆抗体,临床试验表明主要通过抑制粘附过程而防止出现新病灶,对已有病灶也有减轻炎症反应的作用,从而减少复发。 相似文献
