Abstract

Background: Nickel-containing devices, such as the Amplatzer PFO Occluder and Gore® Cardioform Septal Occluder (GSO), are used for transcatheter patent foramen ovale (PFO) closure. However, the impact of nickel hypersensitivity on post-procedural outcomes remains poorly understood. This study aimed to evaluate the risk of adverse events, in patients with nickel hypersensitivity undergoing PFO closure. Methods: Our study was a prospective, double-blinded, randomized study enrolling patients with cryptogenic stroke and PFO-related ischemic stroke to receive either the Amplatzer or GSO device. Nickel hypersensitivity was assessed using skin patch testing. The primary endpoint was the incidence of device syndrome, a composite of patient-reported symptoms (chest pain, palpitations, migraines, dyspnea, and rash). Results: Of the 96 patients, 28 (29.2%) had nickel hypersensitivity. The incidence of device syndrome was significantly higher in patients with nickel hypersensitivity compared to those without (71.4% vs. 20.6%, p < 0.001). Specifically, new-onset or worsening migraines and palpitations were more frequent in nickel-hypersensitive patients. No significant differences were observed in documented arrhythmias, bleeding, or stroke. Multivariable analysis showed that nickel hypersensitivity was associated with a 10.5-fold increase in the odds of device syndrome (aOR = 10.53, 95% CI: 3.17-35.00, p < 0.001). The incidence of device syndrome was similar for both devices. Conclusions: Patients with nickel hypersensitivity are at significantly higher risk for developing device syndrome after PFO closure. Both the Amplatzer and GSO devices demonstrated comparable safety and efficacy in this population. These findings highlight the need for further research to optimize device selection and improve outcomes in nickel-hypersensitive patients.

有或没有镍过敏的患者的卵圆孔未闭:一项随机试验。
背景:含镍装置,如Amplatzer PFO闭塞器和Gore®Cardioform Septal occlder (GSO),用于经导管卵圆孔未闭(PFO)闭合。然而,镍超敏对术后预后的影响仍然知之甚少。本研究旨在评估镍过敏患者进行PFO闭合的不良事件风险。方法:我们的研究是一项前瞻性、双盲、随机研究,纳入隐源性卒中和pfo相关缺血性卒中患者,接受Amplatzer或GSO装置。采用皮肤贴片试验评估镍超敏反应。主要终点是器械综合征的发生率,这是患者报告的症状(胸痛、心悸、偏头痛、呼吸困难和皮疹)的组合。结果:96例患者中有28例(29.2%)发生镍过敏。镍超敏患者的器械综合征发生率明显高于无镍超敏患者(71.4% vs. 20.6%, p < 0.001)。具体来说,新发或恶化的偏头痛和心悸在镍过敏患者中更常见。在记录在案的心律失常、出血或中风方面没有观察到显著差异。多变量分析显示,镍超敏与器械综合征发生率增加10.5倍相关(aOR = 10.53, 95% CI: 3.17-35.00, p < 0.001)。两种器械的器械综合征发生率相似。结论:镍超敏患者在PFO闭合后发生器械综合征的风险显著增加。Amplatzer和GSO装置在该人群中均显示出相当的安全性和有效性。这些发现强调了进一步研究优化设备选择和改善镍过敏患者预后的必要性。
