概括
大脑脊髓液 (CSF) 胰岛素样生长因子结合蛋白7 (IGFBP7) 在多发性硬化症 (MS) 中显示出诊断潜力. 将IGFBP7与瘤坏死因子-α (TNF-α) 结合起来,显著提高了MS的诊断准确性.
科学领域:
- 神经免疫学 神经免疫学
- 生物标志物发现发现
- 多发性硬化症的发病因子
背景情况:
- 神经炎症是多发性硬化症 (MS) 的关键,由细胞因子驱动,但它们的诊断效用是不一致的.
- 胰岛素样生长因子结合蛋白7 (IGFBP7) 在MS炎症和修复中的作用尚不清楚.
研究的目的:
- 在MS中评估血清/CSF细胞因子和IGFBP7的诊断和临床相关性.
- 评估IGFBP7与细胞因子的结合是否提高了MS的诊断歧视.
主要方法:
- 追溯 (139个MS与148个对照) 和前性 (20个MS与40个对照) 队列.
- 通过免疫试验/ELISA量化TNF-α,IL-1β,IL-6,IL-8和IGFBP7.
- 分析了群体差异,多发性硬化症亚型,残疾相关性和诊断性能.
主要成果:
- 在MS患者中血清/CSFTNF-α和IL-8的水平较高.
- 在MS中,CSF IGFBP7与CSF TNF-α正相关 (P < 0.001).
- 脑脊髓中TNF-α (AUC=0.711) 和IGFBP7 (AUC=0.885) 显示出诊断效用;组合改善了它 (AUC=0.939).
结论:
- 脑脊髓IGFBP7与脑脊髓TNF-α有关,表明在MS中具有潜在的诊断价值.
- 一个双标记模型 (CSF IGFBP7 + TNF-α) 提高了MS诊断性能.
- IGFBP7可能反映出与MS相关的炎症过程.

Correlations
36.6K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Correlation and Causation
43.0K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Correlation
15.2K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Inflammatory Response
17.1K
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,...

Inflammatory Response II: Inflammatory Exudate and Tissue Repair
8.1K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...
