免疫检查点抑制剂 (ICI) 可以通过破坏抗炎途径引起免疫介导性结肠炎 (ImC). 需要新的治疗方法来管理这种副作用,而不会影响癌症治疗.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 胃肠病学 胃肠病学
背景情况:
- 免疫检查点抑制剂 (ICI) 改善癌症的结果,但可以导致免疫介导性结肠炎 (ImC).
- ImC的结果是抑制自然的抗炎机制,导致显著的发病率和死亡率.
- 了解IMC的病理生理学对于管理这种不良事件至关重要.
研究的目的:
- 审查ICI诱导的免疫介导性大肠炎 (ImC) 的临床和病理生理方面.
- 突出目前和新的治疗策略来管理IMC.
- 强调需要治疗方法,平衡癌症反应和副作用管理.
主要方法:
- 对ICI诱导性结肠炎的临床研究和病理生理学研究的文献综述.
- 分析T细胞,髓状细胞和肠道微生物群在IMC发育中的作用.
- 对ImC的现有和新兴治疗选择的评估.
主要成果:
- ICI激活T细胞,并在结肠中招募髓质细胞,导致炎症.
- 肠道微生物群在免疫失调和IMC的屏障功能障碍中发挥着重要作用.
- 目前的治疗包括皮质类固醇,抗TNF-α和抗整体素α4β7抗体.
结论:
- 由ICI引起的结肠炎是一个重大问题,需要有效的管理策略.
- 新的治疗方法对于避免损害抗瘤免疫力至关重要.
- 需要进一步研究IMC的发病和治疗.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
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...
