Current guidelines recommend complete extraction of cardiovascular implantable electronic devices (CIEDs) in the case of persistent or recurrent fungemia without other identifiable sources, though supporting evidence is lacking. We sought to evaluate the prognosis of patients with candidemia and CIEDs.
Twelve consecutive patients (54 ± 12 years, 8 male) with CIED and concurrent candidemia were reviewed.
At the time of diagnosis with candidemia, seven patients were immunocompromised, six were on long-term antibacterial therapy, two were intravenous drug users, four were on chronic hemodialysis, and six had a central venous catheter. Four patients were confirmed as definite CIED infection as vegetation was visible on lead by echocardiogram. The other 8 patients were considered possible CIED infection with candidemia of unknown focus. All patients with visible vegetation underwent CIED removal without complications, and other patients were initially managed non-operatively. After 1 year of follow-up, 7 patients had died and at extended follow-up, all patients without lead removal died while 3 of 4 patients with lead extraction survived. Of note, 50% of deaths in the patients without lead removal were associated with fungal sepsis.
Candida fungemia is associated with a high mortality. CIED removal should be an early consideration in these patients even if lead vegetations are not seen.
目前的指南建议在持续性或复发性真菌血症且无其他明确来源的情况下,彻底取出心血管植入式电子设备(CIED),尽管缺乏支持证据。我们旨在评估并发念珠菌血症和 CIED 的患者的预后。
回顾了 12 例连续的(54±12 岁,8 名男性)CIED 合并念珠菌血症患者。
在诊断为念珠菌血症时,7 名患者免疫功能低下,6 名患者长期接受抗菌治疗,2 名患者为静脉吸毒者,4 名患者接受慢性血液透析,6 名患者有中心静脉导管。4 名患者被确认为明确的 CIED 感染,因为超声心动图可见导线上有赘生物。其余 8 例患者被认为是可能的 CIED 感染,其念珠菌血症的来源不明。所有可见赘生物的患者均无并发症地进行了 CIED 移除,其他患者最初接受非手术治疗。在 1 年的随访中,7 名患者死亡,在延长的随访中,所有未移除导线的患者均死亡,而 4 名移除导线的患者中有 3 名存活。值得注意的是,未移除导线的患者中有 50%的死亡与真菌感染性败血症有关。
念珠菌血症与高死亡率相关。即使未看到导线赘生物,也应早期考虑移除 CIED。
