真菌血症31例临床分析

目的对真菌血症的临床及微生物学特征进行分析,为临床诊治提供参考。方法收集2004年8月—2005年12月期间我院31例真菌血症患者的临床资料进行回顾分析。结果超过80%的真菌血症患者患有2种或以上的基础疾病。半数以上患者均有导管留置,而且83．9%患者在血培养采样前1周内均不同程度使用抗菌药物。31例真菌血症中,24例(77．4%)与念珠菌有关,但仅3例由白念珠菌引起,念珠菌血症患者的病死率为45．8%。不同念珠菌对抗真菌药物存在不同程度的耐药率。结论真菌血症多发生于基础疾病严重者,由非白念珠菌导致的败血症在真菌血症中占很大比例;部分真菌对氟康唑、伊曲康唑耐药。

Clinical analysis of 31 patients with fangemia

Objective To investigate the epiderniology of fungemia and provide evidence for clinical therapy.Methods A retro- spective survey was done with the 31 cases of fungemia in our hospital from August 2004 to November 2005.Results More than 80% of the patients suffered from two and more underlying diseases.Over a half of infections developed following placement of catheters.And 83.9% of the patients had a history of antimicrobial agents use before blood culture.The pathogens of 24 (77.4%) cases were associated with Candida spp.Only 3 strains were C.albicans.The mortality rate of candidemia was 45.8%.Different Candida species had different resistance rates to antifungal agents.Conclusions Fungemia patients often have serious underlying diseases.Most fungemia cases were candidemia caused by non-C.albicans.Some fungal pathogens are re- sistant to fluconazole and itraconazole.
