概括
克罗恩病患者中中肠脂肪组织 (MAT) 体积增加预示着对抗TNF-α治疗的反应较差. 较高的MAT体积与更大的剂量调整需求和手术风险增加有关.
科学领域:
- 胃肠病学 胃肠病学
- 免疫学 免疫学 免疫学
- 放射学 放射学是一门学科.
背景情况:
- 克罗恩氏病 (CD) 的特征是炎症,并可能涉及中肠脂肪组织 (MAT) 过度缩小.
- 在CD中,MAT体积和治疗反应之间的关系尚未完全理解.
研究的目的:
- 为了调查中肠脂肪组织 (MAT) 体积是否预测了在生物原始的克罗恩病患者中对抗瘤坏死因子-α (抗TNF-α) 治疗的反应.
- 评估MAT体积作为治疗结果的潜在生物标志物.
主要方法:
- 分析了一组50名生物原始的CD患者,在开始抗TNF-α治疗之前接受CT或MRI.
- 量化了中肠脂肪组织 (MAT) 的体积,不包括大型血管.
- 多变量逻辑回归确定了MAT体积作为抗TNF-α治疗反应的预测指标,评估了剂量强化,手术和3个月和12个月的戒断.
主要成果:
- 较高的中腔脂肪组织 (MAT) 容量独立地与12个月内对抗TNF-α剂量强化更大的需求有关 (aOR:1.36).
- 增加的MAT体积也预测了在3个月内更高的克罗恩病手术风险 (aOR:1.65).
- MAT体积与患者体重和年龄有正相关性.
结论:
- 介质脂肪组织 (MAT) 体积是生物先验克罗恩病患者对抗TNF-α治疗反应不佳的重要预测指标.
- MAT体积可以作为一种有价值的工具,用于识别可能需要治疗升级或手术的患者.
- 这一发现可能有助于克罗恩病的个性化治疗策略.

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
755
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
880
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...
