To report 2 cases of donor-to-host transmission of Candida albicans interface keratitis after Descemet stripping automated endothelial keratoplasty (DSAEK).
We performed clinical and microbiologic examinations on 2 patients who underwent DSAEK for pseudophakic corneal edema.
Two patients underwent uneventful DSAEK surgery using corneal tissue from the same donor. The donor corneoscleral rims were cultured at the time of surgery and both rims subsequently grew C. albicans and Candida glabrata. Approximately 5 weeks after surgery, infiltrates were noted in the DSAEK interface in both of these patients. Despite treatment with antifungal therapy, the Candida keratitis was unable to be controlled medically and required surgical intervention in each case, after which there was no recurrence of infection.
Candida interface keratitis can occur after DSAEK. These 2 cases emphasize the importance of donor corneoscleral rim cultures, especially with the increase in lamellar and endothelial keratoplasty, which can make such interface infections more difficult to diagnose and treat. Patients with fungal positive donor corneal rim cultures should be prophylactically treated with antifungal therapy.
报告2例在Descemet膜剥除自动内皮角膜移植术(DSAEK)后发生供体到宿主的白色念珠菌性界面角膜炎的病例。
我们对2例因人工晶状体性角膜水肿接受DSAEK手术的患者进行了临床和微生物学检查。
2例患者使用来自同一供体的角膜组织顺利接受了DSAEK手术。手术时对供体角膜巩膜缘进行了培养,随后两个边缘均培养出白色念珠菌和光滑念珠菌。术后约5周,这2例患者的DSAEK界面均出现浸润。尽管进行了抗真菌治疗,但念珠菌性角膜炎在药物治疗下无法得到控制,每例均需要手术干预,术后感染未复发。
DSAEK术后可发生念珠菌性界面角膜炎。这2例病例强调了供体角膜巩膜缘培养的重要性,尤其是随着板层和内皮角膜移植术的增加,此类界面感染可能更难诊断和治疗。供体角膜缘培养真菌阳性的患者应接受抗真菌预防性治疗。
