Torulopsis glabrata is a yeastlike fungus that has recently become recognized as an important opportunistic pathogen. Only four cases of T glabrata infection in neonates have been reported. We report two cases of fungemia caused by this organism in premature infants. Both patients were treated with amphotericin B and survived the fungemia, but one patient later died of bacterial sepsis. Both patients had been treated with surfactant, artificial ventilation, intravascular catheters (arterial and venous), broad spectrum antibiotics, and hyperalimentation, which appear to be risk factors for T glabrata fungemia. A review of the literature indicates that T glabrata is susceptible to amphotericin B and 5-fluorocytosine and is resistant to fluconazole. In addition, it is less susceptible to ketoconazole, clotrimazole, and itraconazole than is Candida albicans. We recommend that T glabrata infections be treated initially by reducing iatrogenic risk factors and beginning amphotericin B therapy. If necessary, 5-fluorocytosine should be added to the drug regimen.
光滑念珠菌是一种酵母样真菌,最近已被确认为一种重要的机会致病菌。新生儿光滑念珠菌感染仅报道过4例。我们报告两例由该菌引起的早产儿真菌血症。两名患者均接受了两性霉素B治疗,并在真菌血症中存活下来,但其中一名患者后来死于细菌性败血症。两名患者均接受过表面活性剂、人工通气、血管内导管(动脉和静脉)、广谱抗生素和胃肠外营养治疗,这些似乎都是光滑念珠菌真菌血症的危险因素。文献回顾表明,光滑念珠菌对两性霉素B和5-氟胞嘧啶敏感,对氟康唑耐药。此外,与白色念珠菌相比,它对酮康唑、克霉唑和伊曲康唑的敏感性较低。我们建议,对于光滑念珠菌感染,最初应通过降低医源性危险因素并开始两性霉素B治疗。如有必要,应在药物治疗方案中加入5-氟胞嘧啶。
