慢性肝衰竭患者侵袭性真菌感染的危险因素分析

目的 探讨慢性肝衰竭(Chronic liver failure,CLF)患者合并侵袭性真菌感染(Invnsivefunsal infections,IFl)的危险因素及防治措施.方法 回顾性分析52例CLF合并IFI患者的I临床特点、危险因素以及预后,并与随机选取同期住院的52例CLF未合并真菌感染患者作为对照.结果 52例真菌感染者发生了69例次不同部位感染,感染部位虽然以浅部口腔为主,但是其他部位感染有上升趋势,尤其是肺部感染;感染真菌种属虽然仍以白色念珠菌为主,但是新型隐球菌及曲霉菌有上升趋势;卡方检验、多因素Logistic回归模型及Ridit检验分析显示,危险因素为细菌感染的种类、总胆红素水平、住院天数、抗细菌药物累积时间、侵袭性操作次数、抗细菌药物的种类以及合并腹水的程度;CLF合并IFI死亡率远高于未出现真菌感染患者.结论 CLF合并IFI预后差,有效的预防措施为:积极治疗原发病,缩短住院时间,严密监测患者体液标本,尽早明确感染源,合理使用抗生素,减少或避免侵袭性操作,给予免疫激活剂,注意定期空气消毒.

Analysis of risk factors of patients with chronic liver failure complicated invasive fungal infections

Objective To evaluate the risk factors of chronic liver failure(CLF) complicated invnsive fungal infections(IFI) and prevention and treatment. Methods The clinical data and risk factors of 52 patients with CLF complicated IFI were analyzed retrospectively and were compared with those not complicated IFI. Risk factors were analyzed by chi-square test and Logistic regression test and Ridit test. Results In 52 patients with CLF complicated IFI, there were 69 fungal infections in different tissue and organs, the most were in oral cavity, but other tissue and organs especially bellows infections were rising. Candida albieans infeefions were the most, but cryptococcus neoformans infections and aspergillus infections were rising. The risk factors included species of bacteria infections, serum total bilimbin, hospital days, times of antibiotics using, number of invasive operation,species of antibiotics and degrees of aseites. The mortality of patients with CLF complicated IFI were much higher than those not complicated IFI. Conclusion Patients with CLF complicated IFI have poor progress and prognosis. The effective prevent methods are treating primary disease actively, reducing hospital days, detecting patients' body fluids closely, identifying source of infection as early as possible, using antibiotics correctly, reducing or avoiding invasive operation, using immunoactivators and disinfecting air regularly.
