Objective The objective of this study was to examine the potential relationship between leukocytoclastic vasculitis (LCV), a small-vessel vasculitis, and neuropathy. While LCV primarily affects the skin, its systemic involvement, including the development of neuropathy, has been increasingly recognized. This study aimed to assess whether LCV patients have a higher risk of developing neuropathy compared to a demographically matched control group. Materials and methods This retrospective cohort study utilized data from the TriNetX database (TriNetX, LLC, Cambridge, Massachusetts, USA). A total of 4,519 patients diagnosed with LCV were matched with 4,519 control patients based on demographic factors such as age, sex, and race to ensure comparable baseline characteristics between groups. Neuropathy in both groups was identified using the ICD-10-CM diagnostic code G62.9. Statistical analysis was performed to evaluate the relative risk of neuropathy in LCV patients compared to the control group. Results The analysis revealed that 5.4% of LCV patients were diagnosed with neuropathy, while 4.6% of the control group were affected. This difference was statistically significant, with a relative risk (RR) of 1.209, indicating that LCV patients have a 20.9% higher risk of developing neuropathy than controls (95% confidence interval (CI): 1.009-1.448, p = 0.0396). These findings suggest that LCV may contribute to the development of neuropathy. Conclusion This study provides evidence supporting the association between LCV and an increased risk of neuropathy. The findings highlight the potential for systemic neurological complications in patients with LCV, which may be attributed to vasculitic damage to the nerve blood supply. Despite the challenges in diagnosing LCV-associated neuropathy, the study underscores the importance of vigilant monitoring for neurological symptoms in LCV patients.
目的 本研究的目的是探讨白细胞破碎性血管炎(LCV,一种小血管血管炎)与神经病变之间的潜在关系。虽然LCV主要影响皮肤,但其全身性累及,包括神经病变的发生,已越来越受到认可。本研究旨在评估与人口统计学匹配的对照组相比,LCV患者发生神经病变的风险是否更高。
材料和方法 这项回顾性队列研究利用了TriNetX数据库(美国马萨诸塞州剑桥市的TriNetX有限责任公司)的数据。根据年龄、性别和种族等人口统计学因素,将总共4519例诊断为LCV的患者与4519例对照患者进行匹配,以确保两组之间具有可比的基线特征。使用ICD-10-CM诊断代码G62.9识别两组中的神经病变。进行统计分析以评估LCV患者与对照组相比发生神经病变的相对风险。
结果 分析显示,5.4%的LCV患者被诊断为神经病变,而对照组中有4.6%受到影响。这种差异具有统计学意义,相对风险(RR)为1.209,表明LCV患者发生神经病变的风险比对照组高20.9%(95%置信区间(CI):1.009 - 1.448,p = 0.0396)。这些发现表明LCV可能促成神经病变的发生。
结论 本研究提供了支持LCV与神经病变风险增加之间关联的证据。研究结果突出了LCV患者发生全身性神经并发症的可能性,这可能归因于血管炎对神经血液供应的损害。尽管诊断LCV相关神经病变存在挑战,但该研究强调了对LCV患者的神经症状进行密切监测的重要性。
