简介:Azathioprine当前是在煽动性的肠疾病的维护治疗的关键药。然而,仍然有要决定的一些实际问题:一个人是我们多长必须维持这药。给疾病是标明日期长期的、非可医好的条件的那煽动性的肠,治疗应该是不定的,仅仅功效的损失或严肃的副作用的外观可以引起退却。关于到功效和他们的维护随着时间的过去,证据从长远的观点看支持这药的连续实用性:事实上,它的退却很实质地增加恶化的风险。关于副作用,azathioprine是一很好相对容忍了药和甚至不定的使用似乎安全。延长使用的主要理论风险将是癌症的骨髓中毒性,hepatotoxicity,和发展。事实上,严肃的骨髓抑制或严肃的肝损坏是不平常的,并且能与这药的合适的使用被最小化。最近的遇见的分析建议淋巴瘤的风险是真实的,但是单个风险是相当低的,并且决定分析从长远的观点看建议有利利益/风险比率。在有azathioprine谁有效、很好容忍的煽动性的肠疾病的病人,因此,这药不应该被停止。这个建议作为单个维护药使azathioprine的使用担心,并且对收到伴随物生物制品疗法的病人未必适用。

简介:煽动性的肠疾病(IBD)包括二个实体,Crohn的疾病和ulcerative。两个是有经常的复杂并发症和外科的过程的长期的条件,一个伟人影响病人生命的质量。thiopurine抗代谢物azathioprine和6-mercaptopurine广泛地在IBD病人被使用。当前的指示包括维护治疗,类固醇家属疾病,管闭合,infliximabimmunogenicity的预防和Crohn的疾病复发的预防。令人惊讶地,在最后十年的抑制免疫力的药的宽使用没减少外科的需要,可能因为这些治疗在疾病路线在太迟了的阶段被介绍。immunossupressants的更早的使用现在被一些作者倡导。合理包括:(1)修改现在的治疗学的途径的IBD自然科学的失败,(2)那个azathioprine罐头导致粘膜的愈合的示范,为Crohn的疾病和ulcerative的一个相关预示的因素,并且(3)早immunossupression有的示范很积极的影响在上小儿科,最近诊断的Crohn的疾病病人。我们现在正在等候新研究的结果,诊断了成年Crohn的疾病病人(阿兹台克人学习),与infliximab(声音的学习)相比澄清azathioprine的贡献,并且在最近表明azathioprine的实用性。
