概括
关节骨关节炎 (OA) 不会增加肺癌患者患检查点抑制剂诱导的炎症性关节炎 (ICI-IA) 的风险. 然而,ICI-IA在本研究中与降低死亡率有关.
科学领域:
- 在瘤学瘤学.
- 类风湿病学 类风湿病学
- 放射学 放射学是一门学科.
背景情况:
- 检查点抑制剂治疗是各种癌症的关键治疗方法.
- 免疫相关的不良事件,包括炎症性关节炎,是常见的副作用.
- 预先存在的疾病,如关节骨关节炎在这些不良事件的发展中的作用尚未得到充分理解.
研究的目的:
- 调查关节骨关节炎是否是检查点抑制剂诱导炎症性关节炎 (ICI-IA) 的危险因素.
主要方法:
- 对接受ICI治疗的胸腺癌患者的回顾性分析.
- 使用CT扫描来评估关节骨关节炎 (Kellgren-Lawrence等级≥2).
- 使用统计模型,使用关节骨质炎和没有关节骨质炎的患者之间的ICI-IA发病率和整体存活率进行了比较.
主要成果:
- 在309名患者中,有103名患者在CT扫描上患有部骨关节炎.
- 在患有关节骨质炎和没有关节骨质炎的患者之间,ICI-IA的发病率没有显著差异 (p=0.78).
- 更高的BMI与较低的ICI-IA风险相关 (HR 0.93,p=0.049),而ICI-IA和更高的BMI与更好的生存率相关.
结论:
- 在CT检测下发现的关节骨关节炎并不是肺癌患者患ICI-IA的重要危险因素.
- 在这个患者队列中,ICI-IA与死亡率的降低有关.
- 进一步的研究可能会探索对ICI-IA发展有助于的其他因素.

The JAK-STAT Signaling Pathway
12.1K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
493
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...

Inflammatory Response
16.0K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Autoimmune Disorders
1.5K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.
