药物遗传学可以通过识别遗传变异来优化对炎症性肠病 (IBD) 的生物选择. 本综述强调了与治疗反应相关的单核酸多态 (SNP),有助于个性化医疗策略.
科学领域:
- 胃肠病学 胃肠病学
- 药物遗传学 药物遗传学
- 免疫学 免疫学 免疫学
背景情况:
- 炎症性肠病 (IBD),包括克罗恩氏病和性结肠炎,是一种具有显著发病率的慢性消化系统疾病.
- 目前用于IBD的生物疗法虽然具有革命性,但在有效性和毒性方面表现出相当大的个体间变异性,导致治疗失败.
- 需要个性化治疗策略来最大限度地提高治疗效益,并最大限度地减少IBD患者的不良事件至关重要.
研究的目的:
- 审查有关IBD中对生物剂反应相关的遗传变异的当前知识.
- 确定潜在的预测生物标志物,以优化IBD管理中的生物选择.
- 探索药物遗传学在定制IBD治疗策略中的作用.
主要方法:
- 在多个数据库中进行了全面的文献搜索.
- 在选择相关研究时,采用了包含和排除的标准.
- 这次审查包括了28份报告,从最初的1685个结果.
主要成果:
- 遗传变异,特别是单核酸多态性 (SNP),与对IBD生物药物的差异性反应有关,如infliximab,adalimumab,ustekinumab和vidolizumab.
- 发现的显著SNP主要与免疫系统功能有关,包括免疫力,细胞因子生产和免疫认知.
- 这些SNP显示出作为患者分层和治疗反应的预测生物标志物的潜力.
结论:
- 药物遗传学为优化IBD生物治疗选择提供了一个有希望的途径.
- 识别特定的SNP可以帮助预测患者对生物制剂的反应,从而实现个性化治疗方法.
- 对这些遗传生物标志物的进一步研究对于推进IBD精准医学至关重要.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
