肺部白色念珠菌与非白色念珠菌感染危险因素的比较

摘要

目的 探讨肺部白色念珠菌与非白色念珠菌感染危险因素的差异.方法 对近5年我院176例侵袭性肺部真菌感染病例进行回顾性分析.结果 176例患者感染白色念珠菌120株(60.3%),非白色念珠菌79株(39.7%).除神经系统疾病分布倾向于非白色念珠菌组外,其他各系统疾病两组间分布比较无明显差异.年龄≥65岁患者趋向于感染白色念珠菌,年龄<65岁,入住ICU,接受各种医源性操作(气管插管/切开,机械通气,留置导尿管)的患者则趋向于感染非白色念珠菌.年龄≥65岁为白色念珠菌感染的独立危险因素,非白色念珠菌感染的危险因素为留置导尿管.结论 肺部白色念珠菌与非白色念珠菌感染危险因素的不同,有助于预防性抗真菌治疗药物的选择.%Objective This study we sought to identify differences in risk factors of invasive pulmonary fungous infection caused by Candida albicans and non-albicans candida species.Methods A retrospective chart review was conduct which including 176 patients with invasive pulmonary fungous infection during 2003-2005 in Wuhan Union Hospital.Results There were 176 patients to be infected with 120 strains of Candida albicans (60.3%) and 79 strains of non-albicans candida(39.7%).Except the nervous system disease,there was no significant different distribution of other underlaying diseases between the two groups.Patients whose age≥65 years were more likely to be infected with Candida albicans,while age<65years,in the intensive unit care and accept iatrogenic operations(tracheal intubation/incision, anical ventilation,urethral catheter in) were more likely to have non-albicans candida species infection.Multiple regression analysis showed the significant risk factor for Candida albicans was age≥65 years,and urethral catheter in was the significant risk factor for non-albicans candida species.Conclution The different in the risk factors between Candida albicans and non-albicans candida species may provide help to initiate empiric therapy.
