Fungemia due to is rare and highly resistance to antifungal therapy. Since most cases of fungemia are attributed to medical devices, limited information is currently available on infection without central venous catheter (CVC) implantation. We herein report a case of fungemia without implantation of CVC, successfully treated by liposomal amphotericin B (L-AMB). . An 81-year-old man with a history of chronic obstructive lung disease and rheumatoid arthritis was admitted with dyspnea and fever. The present case had no previous history of CVC implantation. Candidemia was suspected based on yeast and salmon-pink colonies in blood cultures, and thus, micafungin (MCFG) was administered. The isolated yeast was identified as , which exhibited resistance to MCFG. Therefore, antifungal therapy was changed to L-AMB. The sterile blood culture and defervescence were observed from the initiation of L-AMB.
Although the obvious entry point was unclear, long-term immunosuppressive therapy for RA may have damaged the gastrointestinal tract, which leading to the bacterial translocation of . An early class switch to L-AMB was effective. Physicians need to consider the administration of L-AMB in cases suspected of fungemia following the detection of salmon-pink colonies in blood cultures.
由[未提及具体真菌名称]引起的真菌血症罕见且对抗真菌治疗高度耐药。由于大多数[未提及具体真菌名称]真菌血症病例归因于医疗器械,目前关于无中心静脉导管(CVC)植入的感染的信息有限。我们在此报告一例未植入CVC的[未提及具体真菌名称]真菌血症病例,通过脂质体两性霉素B(L-AMB)成功治疗。一名81岁男性,有慢性阻塞性肺疾病和类风湿关节炎病史,因呼吸困难和发热入院。该病例既往无CVC植入史。根据血培养中的酵母和鲑鱼粉红色菌落怀疑念珠菌血症,因此给予米卡芬净(MCFG)。分离出的酵母被鉴定为[未提及具体真菌名称],其对MCFG耐药。因此,抗真菌治疗改为L-AMB。从开始使用L-AMB起观察到血培养无菌且退热。
尽管明显的感染入口不明,但类风湿关节炎的长期免疫抑制治疗可能损害了胃肠道,导致[未提及具体真菌名称]的细菌易位。早期换用L-AMB有效。医生在血培养中检测到鲑鱼粉红色菌落后怀疑[未提及具体真菌名称]真菌血症的病例中需要考虑使用L-AMB。
