, a yeast frequently mistaken for , has emerged in recent years as an opportunistic fungal pathogen, showing a predilection towards patients with immunosuppression, or those with long-term central venous access. This report describes a central line associated bloodstream infection (CLABSI) due to , in a young child, which was successfully treated.
The patient is a 5-year-old male with a history of short gut syndrome, and total parenteral nutrition (TPN) dependence who presented to the emergency room with a two-day history of productive-cough, rhinorrhea, and fever. Antibiotic therapy was initiated with cefepime and vancomycin for suspected CLABSI. However, within the first twenty-four hours of his admission, his initial blood culture from his central venous catheter became positive for yeast so fluconazole was added due to suspicion of candidemia. During his admission, his initial central line and peripheral blood culture were later speciated as , with susceptibilities to fluconazole (MIC: 4 μg/mL) and micafungin (MIC: 0.125 μg/mL). After evaluating the susceptibilities, he was transitioned to micafungin.
This case report further acknowledges that while rare, is an emerging pathogen that has the potential to be life threatening if not accurately identified and treated with the optimal, empiric antifungal therapy. Due to potentially high mortality and antifungal resistance, this yeast species should be on the differential in patients that present with a central venous catheter and/or other underlying risk factors. Favorable outcomes can be achieved by removing indwelling catheters and administering optimal antifungal therapy.
近年来,一种常被误认为其他菌种的酵母菌已成为一种机会性真菌病原体,它倾向于感染免疫抑制患者或长期有中心静脉通路的患者。本报告描述了一名幼儿因该酵母菌引起的中心静脉导管相关血流感染(CLABSI),该感染已成功治愈。
患者为一名5岁男性,有短肠综合征病史,依赖全胃肠外营养(TPN),因咳嗽、流涕和发热两天到急诊室就诊。因怀疑CLABSI开始使用头孢吡肟和万古霉素进行抗生素治疗。然而,在入院后的头24小时内,他中心静脉导管的首次血培养酵母菌呈阳性,由于怀疑念珠菌血症,加用了氟康唑。在他住院期间,他最初的中心静脉导管和外周血培养后来鉴定为该酵母菌,对氟康唑(MIC:4μg/mL)和米卡芬净(MIC:0.125μg/mL)敏感。评估药敏结果后,他改用米卡芬净。
本病例报告进一步确认,虽然罕见,但该酵母菌是一种新兴病原体,如果不能准确识别并用最佳经验性抗真菌治疗,可能会危及生命。由于潜在的高死亡率和抗真菌耐药性,在有中心静脉导管和/或其他潜在危险因素的患者中,应将这种酵母菌列入鉴别诊断。通过拔除留置导管并给予最佳抗真菌治疗,可以取得良好的治疗效果。
