概括
肥胖不会改变诊断周围假肢关节感染 (PJI) 的生物标志物水平. 对肥胖患者来说,C-反应蛋白 (CRP) 是最好的,而对非肥胖患者来说,CRP-白蛋白比率 (CAR) 是最好的.
科学领域:
- 整形外科 整形外科 整形外科
- 传染性疾病 传染性疾病
- 生物标志物 生物标志物
背景情况:
- 周围假肢关节感染 (PJI) 是关节置换手术后的一种严重并发症.
- 肥胖是一个日益关注的问题,可能会影响PJI的诊断.
- 准确和及时诊断PJI对于有效的治疗和患者的结果至关重要.
研究的目的:
- 调查肥胖对PJI各种生物标志物的诊断准确性的影响.
- 为了比较生物标志物的疗效,如CRP,ESR,纤维素,D-二次体,CAR,CLR和CMR在肥胖患者和非肥胖患者的PJI.
主要方法:
- 一组254名患者被根据BMI分为肥胖 (n=59) 和非肥胖 (n=195) 组.
- 患者进一步分为PJI和无菌性失败 (AF) 组.
- 评估了生物标志物水平和诊断性能 (ROC曲线分析).
主要成果:
- 在PJI患者中,生物标志物水平明显高于两组AF患者 (P < 0.001).
- 肥胖和非肥胖群体之间的生物标志物水平相似.
- 在肥胖群体中,C-反应蛋白 (CRP) 的诊断值最高 (AUC=0.982),而CRP-白蛋白比率 (CAR) 在非肥胖群体中最有效 (AUC=0.935).
结论:
- 肥胖不会影响PJI诊断的总体生物标志物水平.
- 肥胖患者中CRP和ESR的诊断值较高,需要谨慎,以避免假阳性.
- CRP和CAR是对分别肥胖和非肥胖患者诊断PJI的最有效生物标志物.

Obesity
358
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
