概括
在全膝关节整形术 (TKA) 患者中,金属过敏不常见,诊断率低且稳定. 患有金属过敏的患者的TKA修订率较高,但占所有修订的不到1%.
科学领域:
- 整形外科 整形外科 整形外科
- 过敏和免疫学 过敏和免疫学
- 医疗器械研究 医疗器械研究
背景情况:
- 金属过敏是膝关节全关节整形术 (TKA) 中未被认可的问题.
- 了解金属过敏的临床负担对于患者管理和设备开发至关重要.
研究的目的:
- 分析在一般人群和TKA人群中对金属过敏性诊断的国家趋势.
- 为了比较具有和没有金属过敏症的患者之间的TKA修订率.
- 为了追踪"金属敏感"的骨科植入物的市场发布.
主要方法:
- 商业和医疗保险补充数据库 (2018-2023) 的 Merative MarketScan 追溯分析.
- 使用ICD-10代码识别金属过敏症.
- 发生率和TKA修订率的计算.
主要成果:
- 金属过敏的发病率低 (0.019%-0.025%一般,0.133%-0.165%TKA) 和稳定.
- 在TKA患者中,金属过敏诊断率显著增加 (p<0.001).
- 金属过敏症患者的TKA修订率较高 (14.03%与3.15%,p<0.001),占修订率的0.68%.
结论:
- 金属过敏是一种罕见的疾病,在TKA患者中发生率稳定.
- 虽然金属过敏与更高的修订率有关,但它只影响了很小一部分修订案例.
- 目前的流行病学数据可能不支持利基"金属敏感"植入物的发展.

01:19Hypersensitivity Reactions: Immune-Complex Reactions
70
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum...

97
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
