| 目的:探讨血液恶性肿瘤患儿造血干细胞移植后发生阿萨希毛孢子菌血流感染的治疗药物选择。方法:分析1 例造血
干细胞移植后处于免疫抑制状态下血流感染阿萨希毛孢子菌的病例资料,结合既往文献,讨论并分析阿萨希毛孢子菌血流感染
的药物治疗方案。结果:患儿在艾沙康唑治疗过程中发生了阿萨希毛孢子菌血流感染,调整为伏立康唑和两性霉素B 脂质体联
合治疗后,体温恢复正常,炎性指标好转,但由于患儿移植后出现了严重的肺部排斥反应,肺出血未能得到有效控制,最终放弃
治疗。结论:血液恶性肿瘤患儿血流感染阿萨希毛孢子菌病死率高,在临床实践中应结合病情、体外药敏试验结果选择单药或
联合治疗。阿萨希毛孢子菌应首选唑类药物,体外活性最强的是伏立康唑。两性霉素B 抗真菌活性不充分,但与伏立康唑的联
合治疗方案可能较伏立康唑单药或艾沙康唑单药治疗更具优势。 |

| Abstract: |
| Objective: To explore the selection of therapeutic drugs for the treatment of bloodstream infection with Trichosporon asahii
after hematopoietic stem cell transplantation in children with hematologic malignancies. Methods: Clinical data of a child with
bloodstream infection with T. asahii after hematopoietic stem cell transplantation in the immunosuppressed state were analyzed, combined with previous literature, the therapeutic treatment of bloodstream infection with T. asahii was discussed and analyzed. Results:
Bloodstream infection with T. asahii occurred during the treatment of isavuconazole. After adjusting to the combination treatment of
voriconazole and amphotericin B liposome, the body temperature and inflammatory indicators were improved. However, due to the severe
pulmonary rejection after transplantation, the pulmonary hemorrhage could not be effectively controlled, and finally the treatment was
discontinued. Conclusion: Children with hematological malignancies have a high mortality rate due to bloodstream infection with T.
asahii. In clinical practice, single or combination therapy should be selected based on patients’ condition and in vitro drug sensitivity
results. The preferred selection for T. asahii is triazole drugs, with voriconazole being the most active in vitro. Amphotericin B has
insufficient antifungal activity, yet the combination therapy with voriconazole may be more advantageous than voriconazole or
isavuconazole monotherapy. |
