肿瘤化疗患者深部真菌医院感染现状分析

目的调查肿瘤化疗患者深部真菌感染现状,加强感染的防治。方法回顾调查2003年1月-2005年12月,102例肿瘤化疗患者并真菌感染的临床资料,对真菌感染的危险因素、真菌的种类及其耐药性进行单因素分析。结果102例真菌感染以下呼吸道为主,占61.8%,其次为口腔,占16.7%,各种感染性标本培养出真菌102株,以白色念珠菌为主,占71.6%,其次为热带念珠菌,占14.7%,白色念珠菌对氟康唑敏感率最高,为96.2%,对咪康唑的敏感率最低,为78.4%。结论本组肿瘤化疗患者发生真菌感染的原因与原发肿瘤疾病、患者年龄、外周血白细胞数、抗菌药物使用及化疗次数等因素密切有关。

Deep Fungal Isolates from Hospital-acquired Infection in Tumor Patients after Chemotherapy

OBJECTIVE To investigate the pattern of fungal isolates from hospital-acquired infection in tumor patients after chemotherapy. METHODS The clinical information of fungus isolates from 102 tumor patients after chemotherapy was investigated.We analyzed the risk factors,species and drug-resistance of isolates. RESULTS The lower respiratory tract and mouth infection accounted for 61.8% and 16.7% in 102 cases with fungal infection and 102 isolates were isolated from various clinical specimens.Among above 102 isolates,Candida albicans and C.tropicalis accounted for 71.6% and 14.7%.The resistant rate of C.albicans to fluconazole and miconazole were 96.2% and 61.4%,respectively. CONCLUSIONS Hospital-acquired infection resulted from fungi in tumor patients after chemotherapy is related to primary tumor,age,the amount of white cell and use of antibiotics.
