检查点阻断剂诱导的炎症性关节炎中的阴道液
严重的免疫检查点抑制剂诱导的炎症性关节炎 (ICI-IA) 可以模仿败血性关节炎. 这种罕见的疾病表现为关节炎症和白细胞升高,需要仔细诊断以避免治疗延迟.
科学领域:
- 在瘤学瘤学.
- 类风湿病学 类风湿病学
- 免疫学 免疫学 免疫学
背景情况:
- 免疫检查点抑制剂 (ICI) 对于治疗晚期癌症至关重要,但可以诱导与免疫相关的不良影响.
- 炎症性关节炎是ICI已知的不良影响之一,严重病例罕见且定义不佳.
- 区分严重的ICI诱导炎症性关节炎 (ICI-IA) 和其他疾病,如败血性关节炎是具有挑战性的.
研究的目的:
- 描述严重ICI-IA的临床特征.
- 审查关于严重ICI-IA的文献,并将其与败血性关节炎进行比较.
- 突出ICI-IA的诊断挑战和潜在的管理策略.
主要方法:
- 一个患有转移性尿路细胞癌,接受ICI治疗的患者的病例报告,该患者患有严重的多关节性炎症性关节炎.
- 原生关节和假肢关节的关节切除术,以分析结膜液.
- 关于已发表的严重ICI-IA病例的综合文献综述.
主要成果:
- 患者的突液显示白细胞 (WBC) 数量升高,中性粒细胞占主导地位,模仿败血性关节炎.
- 感染性工作结果是负面的,导致ICI-IA的诊断.
- 文献审查显示,类似的病例具有多关节性呈现,炎症标志物升高,并且没有其他类风湿性疾病.
结论:
- 严重的ICI-IA可以呈现出性关节炎的重叠特征,导致诊断不确定性.
- 与中性粒细胞占主导地位的白细胞升高的突流体发现并不排除ICI-IA.
- 建议在怀疑ICI-IA时提前考虑使用类固醇治疗.
